Abstract
Magnesium is one of the most important micronutrients for the human body, is involved in many physiological pathways and is essential for the maintenance of normal cell and organ function. Magnesium deficiency in healthy individuals on a balanced diet is quite rare, but needs may change over the course of life. In women, in particular, there are various physiopathological conditions that may increase magnesium requirements, useful for both disease prevention and treatment. Indeed magnesium is well recognized in obstetrics and gynecology area. Magnesium use in women, both in terms of prevention and treatment, is extended to many health issues from PCOS to pre-menstrual syndrome, from pregnancy to menopause and beyond.

... Acute changes in plasma magnesium levels are noticeable during a continuous bout of moderate-to-high intensity exercise [94]. There is growing evidence to support an essential role of magnesium in various physiological outcomes for women as they age [140]. Normal serum magnesium levels range between 0.75 and 0.95 mmol/L, and magnesium deficiency consists of magnesium levels < 0.75 mmol/L. ...
... Overall, magnesium deficiency in healthy individuals consuming a balanced diet is rare, but dosing requirements may change in response to hormonal variations and training adaptations. Specifically, there are various pathophysiological conditions across the female lifespan, such as use of OCs, pregnancy, and menopause, that may increase magnesium requirements (Fig. 4) [140]. Magnesium supplementation in pre-menopausal women may improve premenstrual syndrome symptoms through decreasing inflammatory markers [141]. ...
... Additionally, as women traverse through menopause, there is an increased risk for hypertension. Emerging data suggest magnesium has an inverse relationship with hypertension risk, suggesting magnesium supplementation may have cardioprotective benefits [140], especially for women. The recommended dietary allowance for magnesium in women is 310-320 mg per day, but magnesium supplementation may be needed if the recommended dietary allowance is not met through the diet alone. ...
Women are the largest consumers of dietary supplements. Dietary supplements can play a role in health and performance, particularly for women. Growing evidence and innovations support the unique physiological and nutrient timing needs for women. Despite the need for more nutrition and exercise-specific research in women, initial data and known physiological differences between sexes related to the brain, respiration, bone, and muscle support new product development and evidence-based education for active women regarding the use of dietary supplements. In this narrative review, we discuss hormonal and metabolic considerations with the potential to impact nutritional recommendations for active women. We propose four potential areas of opportunity for ingredients to help support the health and well-being of active women, including: (1) body composition, (2) energy/fatigue, (3) mental health, and (4) physical health.
... Немаловажен факт роста количества женщин со злокачественными новообразованиями женской репродуктивной системы. Ввиду увеличения числа пациенток, страдающих онкогинекологическими заболеваниями, сохранение их КЖ является приоритетом при оказании реабилитации [6][7][8]. ...
... Кроме того, к причинам возникновения гипомагниемии относят изменение гормонального фона, связанное с ожирением, синдром поликистозных яичников (СПКЯ), диабет 2-го типа, метаболический синдром, системное воспаление, недостаточное алиментарное потребление, повышение скорости метаболизма, в частности при беременности, высоком уровне физической активности, потоотделении. Известно, что многие женщины в современном обществе потребляют недостаточное количество магния [8,18]. В зависимости от страны и возраста рекомендованная норма для женщин от 18 лет варьируется от 232 до 357 мг/сут [19]. ...
Background. In the 21st century, there is a clear trend towards an increase in the proportion of women with climacteric syndrome (CS) and surgical menopause. Medical care for such patients usually includes menopausal hormone therapy (MHT), which often causes changes in magnesium and pyridoxine metabolism and their deficiency, leading to the development of adverse reactions. Therefore, it is necessary to improve rehabilitation programs designed to increаse the quality of life (QoL) for this category of gynecological patients.
Objective : to assess the profile of women with CS and surgical menopause receiving and not receiving MHT and to identify the significance of magnesium deficiency (MD) effect on the recovery process.
Material and methods . The observational non-interventional study included a total of 9168 women, of which 1528 patiеnts with CS and surgical menopause were taking MHT (Group 1), and 1528 patients with CS and surgical menopause were not taking MHT (Group 2). The Magnesium Deficiency Questionnaire (MDQ) was used to determine the number of participants with MD. A biochemical blood test was also performed, including determination of plasma magnesium concentration. The patients’ profile was analyzed for general somatic pathologies, obstetric and gynecological history, complaints, and MD symptoms using visual analogue scale. To assess QoL before the start of 4-week MD replenishing course and at the end of therapy, the World Health Organization Quality of Life Questionnaire (WHOQL-26) was applied.
Results. The MDQ data showed that the prevalence of DM in Group 1 was higher compared to Group 2. In both groups, women with hypomagnesemia had a higher incidence of viral infections, vegetative-vascular dystonia, osteochondrosis and arterial hypertension, more pronounced sleep disorders, irritability, back pain, rapid fatigue, and higher MDQ scores. After completion of the course of therapy with magnesium citrate and pyridoxine combination, the MDQ scores in patients with DM decreased along with an increase in plasma magnesium concentration. Besides, women's satisfaction with their physical, psychological, social wellbeing and microsocial support increased, and self-perception improved. A decrease in the severity of DM and a significant improvement in QoL according to WHOQOL-26 were demonstrated in patients with CS and surgical menopause after therapy.
Conclusion. The profile of patients with CS and surgical menopause, regardless of MHT, is often characterized by DM and decreased QoL. It seems reasonable to include blood magnesium level monitoring and DM correction in the comprehensive rehabilitation program for such patients.
... The specific supplements that achieved consensus in this study included magnesium and liver and adrenal gland support. Supplementation with magnesium has been shown to improve insulin resistance and glucose metabolism and thus may assist fertility parameters in women with PCOS and metabolic disorders (Porri et al. 2021;Skoracka et al. 2021). Magnesium also plays a role in the stress response and studies show that psychological stress could result in a magnesium deficiency; conversely, magnesium deficiency could increase one's susceptibility to stress (Pickering et al. 2020). ...

Homeopathy offers an alternative treatment option for female infertility; however, there is currently no research describing how homeopaths manage this condition in their practice.Aim: To determine homeopathic practitioners’ approaches to managing female infertility.Method: The electronic Delphi technique consisting of three rounds was used to establish consensus among homeopaths. Twelve registered homeopaths with a minimum of 5 years of clinical experience in managing female infertility participated, 11 of whom completed the study. In round one, participants elaborated on interventions found beneficial in clinical practice for female infertility. Responses were qualitatively analysed to create a structured list of items; participants rated their level of agreement with these items on a 5-point Likert scale in the second and third rounds. Consensus was determined for items that reached an agreement level of 75% or more.Results: Thirty-two statements achieved expert consensus, which were placed into the following categories: homeopathic treatment, dietary and lifestyle modifications, supplementation and referrals.Conclusion: The results of this study provide a baseline depicting the homeopathic approach to treating female infertility. Several research gaps have been identified and further studies are necessary to explore these interventions to improve future patient care.Contribution: This study highlights the various approaches used by homeopathic practitioners in the management of female infertility.
... The deficiency of magnesium can lead to insulin resistance, impairing glucose delivery into cells, resulting in high blood glucose levels, fatigue, increased thirst and urination, impaired vision, and other symptoms. The chronic hyperglycemia can cause severe complications over time, including cardiovascular disease, renal damage, and nerve damage (Porri et al., 2021). As a treatment for DM and its consequences, MgNPs show promising effects, and studies on animals and cells indicate that MgNPs increase insulin sensitivity, enhancing cellular response to insulin, lowering glucose level in blood, and decreasing the risk of T2DM. ...
Diabetes mellitus (DM), a metabolic disease, has been rising annually all across the world based on epidemiology. An effective treatment is essential for diabetic patients to improve their quality of life and to prevent the development of chronic diseases. Microelements, also known as trace elements or nanoparticles, are small amounts of chemicals that are present in human body, and are essential for the growth, and development of the body. Over the last several years, there has been a lot of interest in nanoparticles as a novel class of nanomedicines for antidiabetic application. The nanomedicines are based on trace elements or nanoparticles that have the potential to significantly enhance the care and treatment of diabetes by controlling glucose metabolism. According to several researches, nanoparticles can prevent diabetes in various ways, including lowering blood sugar, promoting insulin secretion, reducing glucose intolerance, enhancing insulin sensitivity, modifying lipid profiles, and reducing inflammation and antioxidant stress. This chapter includes a detailed analysis of the physiological functions of nanoparticles, the pathophysiology of diabetes, the current status of diabetes therapy, and many emerging nanoparticles particularly for diabetes. To conclude, nanoparticles can be used as dietary supplements or as nanomedicines to effectively treat diabetes.
... The value of Calcium and Magnesium was in the range of 78-155 mgL −1 and 28-54 mgL −1 respectively in the ground water [16]. Magnesium is essential for maintenance of normal cell functions in various biochemical pathways [17]. The concentration of Magnesium at S3 was 8126 ppb, at S1 was 11634 ppb, at S2 was 31315 ppb and was not found to be significant (S1vs S3 with P value 0.80) may be due to more release of pharma pollutants. ...
Present light was to determine elemental load in Sirsa river ecosystem to know the concentration of toxicants in this Sutlej river's tributary that act as a gutter for industrial effluents of Baddi region. The inductively coupled plasma mass spectroscopy was used to detect concentration of elements in the department of biochemical engineering and biotechnology at IIT Delhi and the collected data was further analyzed statistically using one way ANOVA at (p≤0.05) followed by post hoc Duncan's test to predict degree of variations and comparative profile in Table 1. The application of metal index was also performed to estimate water quality and co-related it with health hazards. Variations in concentration of elements was reported near common effluent treatment plant on pollutant Nallah (S2) in deceasing order read as Mg>Na>Ca>B>Zn>Cu>Mn>Fe>Mo>Al>Tl>Se in ppb. The concentration of elements reported at S1, S2, S3 were within permissible limit of WHO and Bureau of 488 Indian Standards, except the value of Boron, Magnesium and Thallium were exceeded these guidelines constantly at site S2 of study area.The metal index values at S1, S2 and S3 were 1.55, 5.80 and 2.57 respectively. The site S2 was affected strongly due to presence of elemental dust and untreated waste water discharged by chemical industrial units of Baddi region. This site (S2) was nearer to common effluent treatment plant on the bank of Sirsa river and found to be unsuitable at all with more value of metal index. It was also viewed to adopt such scale indices to estimate drinking water quality with respect to concentration of elements after equal interval of time; as there may be seasonal change in the load of debris due to rate of pollutants dumping in the riverine ecosystem which is directly proportional to the content of elements. The load of pollutants in water system was underlined to know the impact of inorganic waste discharges on water quality of river in this region of Himachal Pradesh along industrial belt.
... Trace elements play important roles in biological processes relevant to breast cancer, especially those elements that are essential components of antioxidants [16]. Magnesium is one of the most important element micronutrients for the human body, is involved in many physiological pathways and is essential for the maintenance of normal cell and organ function [17]. Magnesium also plays a role in the progression of breast cancer, and the inherent physiological changes of the disease induce disturbances in the homeostasis of this element, which favors tumorigenesis [18][19][20]. ...
The objective of this study was to evaluate the association of serum vitamin D, serum Calcium, serum Phosphorus and serum Magnesium levels with Breast Cancer risk in Iraqi women. In current study, participated 100 women's, 60 women's with Breast Cancer and 40 women healthy. The status divided to two group's pre-menopausal and post-menopausal group. Concentration of Calcium, Phosphorus and Magnesium were measured using Semi-Auto Analyzer and level of vitamin D were determined by the enzyme-linked fluorescence assay (ELFA) technique. In pre and post-menopausal patients, the mean serum vitamin D, Calcium and Magnesium levels was significantly lower than in control, while serum Phosphorus level in case was higher than in control. A negative correlation was observed between vitamin D, Calcium, Magnesium and Phosphorus with pre-menopausal patients. In post-menopausal patients was observed a negative correlation between vitamin D and Magnesium, while observed a positive correlation between Calcium and Phosphorus with breast cancer. Based on these findings, it can be concluded that vitamin D, Magnesium and Calcium deficiency and high levels of Phosphorus can be considered as risk factors for women's with breast cancer. Therefore, routine screening of these parameters in womans with Breast Cancer is recommended to reduce the incidence of disease. .
... This underscores the necessity for a holistic treatment approach that addresses both mental, and reproductive health. Enlightening the associations of IL-18 Levels as a mediator of the causal links between major depression, anxiety and reproductive health could potentially have an effect on future clinical practice by introducing magnesium supplementation for improving women's overall and reproductive health and well-being [30]. ...
This research has suggested a link between major depressive disorder (MDD) and infertility, with interleukin-18 (IL-18) being proposed as a potential mediator due to its connections to both conditions. A Mendelian randomization (MR) approach was utilized in this study, which drew on genetic data from 500,199 European participants studied for MDD, along with additional IL-18 and reproductive health data from the FinnGen consortium and GWAS datasets. Single nucleotide polymorphisms were employed as instrumental variables to examine the causal relationships between MDD, genetically predicted IL-18 levels, and infertility. In our study, bidirectional MR analysis revealed a significant inverse causal relationship between MDD and genetically predicted IL-18 levels, with a higher genetic predisposition to MDD, correlating with reduced IL-18 levels (β: −0.40; 95% confidence interval (CI): −0.69 to −0.11; P = 7.09 × 10⁻³). Additionally, MDD is found to significantly increase the risk of female infertility. Notably, genetically predicted IL-18 levels demonstrated a protective effect against female infertility (odds ratio (OR): 0.92; 95% CI: 0.86–0.98; P = 1.17 × 10⁻²). Mediation analysis indicated that genetically predicted IL-18 levels partially mediated the impact of MDD on female infertility associated with cervical, vaginal, other or unspecified origin, accounting for up to 14.61% of this effect. No evidence of pleiotropy or heterogeneity was detected. The role of genetic predispositions to MDD in influencing genetically predicted IL-18 levels, and subsequently, female infertility, was highlighted by our study, offering insights into the complex interplay between mental health and reproductive biology. These findings contribute to a deeper understanding of the genetic and molecular pathways influencing these conditions, suggesting new directions for research and potential therapeutic interventions.
... Those insects could therefore be considered as excellent sources of Mg. Magnesium is indispensable in the metabolism of calcium, but is also necessary for the proper functioning of the heart, it is a cofactor of many enzymes involved in energy production in the body [81] and plays an important role in insulin sensitivity [82]. ...
Insects, a traditional food in many parts of the world, are highly nutritious and especially rich in proteins and thus represent a potential food and protein source. They are rich in essential amino acids and unsaturated fatty acids and provide ample quantities of minerals such as Fe, Zn, Mn, Ca, and P essential for human health. The objective of this study was to assess the nutritional value of dried edible caterpillars with an exclusive focus on mineral content. Quantitative analysis of seven essential minerals for humans was analyzed for two dried edible caterpillars currently commercialized in Bukavu town, South Kivu province (eastern DR Congo) central market including Bunaeopsis aurantiaca (Lepidoptera: Saturniidae) and Imbrasia oyemensis (Lepidoptera: Saturniidae). Mineral content analysis of Ca, Mg, Na, Fe, Zn, and Mn were carried out using the Atomic Absorption Spectrophotometer (AAS) while the P content was analyzed using the Colorimetric method, then the mineral content was compared to the recommended daily intakes (mg/day). On a dry weight basis, we find that mineral content differed with type of caterpillar. I. oyemensis had the highest concentrations of most minerals tested compared to B. aurantiaca, which nevertheless had the greatest amount of phosphorus (P). P was significantly the most abundant mineral detected (605.70 ± 6.08 mg/100g; p < 0.001), followed by Mg and Na in I. oyemensis with 220.11 ± 6.10 mg/100g and 216.43 ± 1.08 mg/100g respectively. Oligo-minerals Zn and Fe, were the lowest in the caterpillar samples. All the edible caterpillars analyzed met the recommended daily mineral intake. The consumption of < 28 g and < 8 g of these caterpillars covers daily RNI in adults for Fe and Mn respectively. Thus, edible caterpillars in this study have shown that they can be excellent contributors to people's mineral requirements and should be sustainably utilized. Aside from direct consumption, there is a huge potential for using these caterpillars as raw material and food fortification. The mineral content of commonly eaten caterpillars was analyzed to inform consumers among indigenous populations in the Democratic Republic of Congo about the micro-nutritional quality of the insects.

Introduction
Menopause is an important milestone in the lives of women. Despite it being a natural phenomenon, menopause brings a lot of changes in a woman's life, which significantly affects their health and well-being. Menopause involves the cessation of hormone production necessary for menstrual cycles and fertility of females. The absence of these hormones may disturb the homeostasis of minerals, blood glucose, and lipid parameters and predispose women to several health conditions affecting different organs. Obesity has been identified as one of the several conditions that influence the health of women. Therefore, assessing women's health before menopause may improve understanding of their well-being and predict problems during and after menopause. The present study evaluated the activities of calcium, magnesium, phosphorous, fasting blood glucose (FBG), and lipid parameters in obese and nonobese premenopausal women.
Methods
The present study included 90 obese and 110 nonobese premenopausal women attending the General Medicine and Obstetrics and Gynaecology Departments of Gandhi Medical College and Hospital (GMC&H), Secunderabad, Telangana, India. The body mass index (BMI) was measured in all the study participants to put them under obese and nonobese categories. Blood samples were collected from all the study participants for the estimation of the activities of minerals like calcium, magnesium, phosphorous, FBG, and lipid parameters including total cholesterol (TC), triglycerides (TG), very low-density lipoproteins (VLDL), low-density lipoproteins (LDL), and high-density lipoproteins (HDL).
Results
The results demonstrated a significant difference in the activities of lipid parameters (TC-obese (158.90 ± 20.20 mg/dl) versus nonobese (148.7 ± 18.6 mg/dl), p < 0.05; TG-obese (143.1 ± 58.2 mg/dl) versus nonobese (118.40 ± 55.80 mg/dl), p < 0.01; VLDL-obese (28.30 ± 11.50 mg/dl) versus nonobese (23.30 ± 11 mg/dl), p < 0.05; LDL-obese (92 ± 30.30 mg/dl) versus nonobese (73.90 ± 26.10 mg/dl), p < 0.01; HDL-obese (61.60 ± 12.50) versus nonobese (65.30 ± 11.25 mg/dl), p < 0.01), FBG (obese (106.80 ± 32.20 mg/dl) versus nonobese (88.50 ± 42.60 mg/dl); p < 0.01)), and magnesium (obese (1.79 ± 0.36 mg/dl) versus nonobese (2.42 ± 0.67 mg/dl); p < 0.01)). However, the activities of calcium (obese (9 ± 0.54 mg/dl) vs. nonobese (8.9 ± 0.58); p > 0.05)) and phosphorous (obese (3.84 ± 0.53 mg/dl) versus nonobese (3.75 ± 0.46 mg/dl); p > 0.05)) was found to be similar in obese and nonobese premenopausal women.
Conclusions
The results suggest that obese premenopausal women revealed lowered activities of magnesium that can predispose them to chronic diseases like cardiovascular diseases. In addition, obese women showed higher activities of FBG that predisposes them to type 2 diabetes mellitus (T2DM). There was significant variation in the lipid parameters among obese and nonobese women. However, serum calcium and phosphorous were similar in obese and nonobese premenopausal women.
... The role of Mg 2+ as an essential cofactor in enzymatic ATP hydrolysis activation highlights its critical importance in the realm of energy metabolism and muscle function [51]. Maintaining adequate levels of Mg 2+ has long been recognized as crucial in the prevention of fatigue and the alleviation of muscle cramps and spasms, issues commonly encountered not only by endurance athletes but also by females dealing with menstrual syndromes [52,53]. Elevated levels of muscle Mg 2+ in the EF phase may effectively counteract Ca 2+ to mitigate muscle spasms or twitches resulting from excessive muscle contraction due to Ca 2+ accumulation. ...
The natural variation in estrogen secretion throughout the female menstrual cycle impacts various organs, including estrogen receptor (ER)-expressed skeletal muscle. Many women commonly experience increased fatigue or reduced energy levels in the days leading up to and during menstruation, when blood estrogen levels decline. Yet, it remains unclear whether endogenous 17β-estradiol, a major estrogen component, directly affects the energy metabolism in skeletal muscle due to the intricate and fluctuating nature of female hormones. In this study, we employed 2D 31P FID-MRSI at 7T to investigate phosphoryl metabolites in the soleus muscle of a cohort of young females (average age: 28 ± 6 years, n = 7) during the early follicular (EF) and peri-ovulation (PO) phases, when their blood 17β-estradiol levels differ significantly (EF: 28 ± 18 pg/mL vs. PO: 71 ± 30 pg/mL, p < 0.05), while the levels of other potentially interfering hormones remain relatively invariant. Our findings reveal a reduction in ATP-referenced phosphocreatine (PCr) levels in the EF phase compared to the PO phase for all participants (5.4 ± 4.3%). Furthermore, we observe a linear correlation between muscle PCr levels and blood 17β-estradiol concentrations (r = 0.64, p = 0.014). Conversely, inorganic phosphate Pi and phospholipid metabolite GPC levels remain independent of 17β-estradiol but display a high correlation between the EF and PO phases (p = 0.015 for Pi and p = 0.0008 for GPC). The robust association we have identified between ATP-referenced PCr and 17β-estradiol suggests that 17β-estradiol plays a modulatory role in the energy metabolism of skeletal muscle.
... Instead, its protection on membrane integrity may result from its hydrophobic interaction with the fatty acid moiety of MPLs, presumably through the membrane-bound receptors ERα and ERβ located in lipid rafts (44), 8 The role of Mg2+ as an essential cofactor in enzymatic ATP hydrolysis activation highlights its critical importance in the realm of energy metabolism and muscle function (48). Maintaining adequate levels of Mg2+ has long been recognized as crucial in the prevention of fatigue and the alleviation of muscle cramps and spasms, issues commonly encountered not only by endurance athletes but also by females dealing with menstrual syndromes (49,50). Furthermore, it's noteworthy that natural postmenopausal women typically exhibit lower serum estrogen levels in conjunction with higher magnesium levels when compared to healthy premenopausal women (51). ...

This manuscript focuses on the production of polymeric matrices enriched in minerals and antioxidant compounds. The biopolymers employed are obtained from different by-products of the agro-food industry (porcine plasma protein, pea protein concentrate and soy protein isolate), which helps to revalorize them. Two different manufacturing techniques are employed to produce these matrices: 3D-printing and injection molding. Bioactivity was enhanced through immersion of the samples in magnesium glutamate and iron lactate solutions. To incorporate these minerals and bioactive compounds into the matrices, two additional stages are required: (1) an immersion stage in a mineral/bioactive containing solution, which allows simultaneous removal of the glycerol employed as plasticizer and entrapment of the minerals and bioactive compounds; and (2) a subsequent freeze-drying stage. Matrices produced through these manufacturing processes were assessed through water uptake capacity, mineral analysis, bioactivity and color measurements. The studied matrices have great potential in the food industry, as the threshold for claiming a significant mineral content was reached after the immersion stage. The presence of bioactive compounds could avoid the degradation of these matrices when food processing includes stages at relatively high temperatures.

... Although cardiovascular risk factors are critically important for clinicians to incorporate into their HC treatment recommendations, there are many other health-relevant variables that can impact women's positive and negative responses to HC treatment. For example, research finds that factors such as pre-existing iron deficiencies and environmental factors that impact women's nutritional status and endocrine function (Alvergne et al., 2017Bradley et al., 2009;Mernissi, 1975;Meskele & Mekonnen, 2014) can impact women's moods (e.g., Porri et al., 2021) and responses to HC treatment. ...
Women’s psychological and behavioral responses to hormonal contraceptive (HC) treatment can be highly variable. One of the great challenges to researchers seeking to improve the experiences of women who use HCs is to identify the sources of this variability to minimize unpleasant psychobehavioral side-effects. In the following, we provide recommendations for programs of research aimed at identifying sources of heterogeneity in women’s experiences with HC. First, we review research demonstrating person- and prescription- based heterogeneity in women’s psychobehavioral responses to HCs. Next, we identify several promising person- and prescription- based sources of this heterogeneity that warrant future research. We close with a discussion of research approaches that are particularly well-suited to address the research questions raised in article. Together, this review provides researchers with several promising research pathways to help support the development of a precision medicine approach to HC treatment.

Objectives:
Diabetes mellitus (DM) is a significant public health challenge in Serbia, mirroring the situation in other European middle-income countries. The aims of this study were to examine the disease-related characteristics and management of diabetes, as well as the prevalence of use of dietary supplements (DS) among diabetes patients in Serbia, and to analyze the effects of the coronavirus pandemic on DM patients in Serbia.
Methods:
The study was carried out as an online, observational, cross-sectional study involving 422 adult diabetes type 1 (DM1) and type 2 (DM2) patients residing in Serbia.
Results:
DM1 patients were more likely than DM2 patients to self-control glucose levels (p < 0.001). Almost one-third of DM2 patients (31.4%) did not know their HbA1c value. Polypharmacy has been reported by 9.7% of DM1 patients and 23.5% of DM2 patients. During the coronavirus pandemic increased anxiety levels for one-third of respondents was noticed. The prevalence of DS use among DM patients was very high (95.3%), with vitamin C, zinc, vitamin D and magnesium being the most commonly used. Women were more likely to use vitamin D (p = 0.001) and magnesium DS (p = 0.005) than men. Most patients (76.9%) faced limited access to healthcare services during the coronavirus pandemic with, sometimes, detrimental consequences. A significant portion of respondents (41.2%) consulted a pharmacist more often in 2021 than in previous years.
Conclusions:
Special caution is needed regarding the potential interactions of DS with chronic therapy. To enhance diabetes care, Serbia needs more accessible mental health support, improved diabetes education, expanded CGM availability, and carefully planned emergency healthcare measures for chronic patients.
Background. The increase in the proportion of patients with menopausal syndrome (MS) and surgical menopause, including women in the recovery phase after radical surgical treatment of the reproductive system cancer, is a characteristic trend of the 21st century. Part of them receive menopausal hormone therapy (MHT). This determines the relevance of the analysis of the specified cohort of patients to enhance rehabilitation programs designed to improve the quality of life (QoL) in this category of gynecological patients.
Objective: subanalysis of primary data from the MAGYN study cohort of MHT treated women with MS and surgical menopause.
Material and methods. The MAGYN observational non-interventional study of the real clinical practice included 9168 women, of whom 1528 represented a group of previously not characterized MHT treated women with MS and surgical menopause. To determine the number of patients with magnesium deficiency (MD), a Magnesium Deficiency Questionnaire (MDQ) was used, a biochemical blood test with an indicator of serum magnesium concentration was evaluated. The profile of the participants was analyzed by the presence of general somatic pathologies, obstetric, gynecological history, complaints, symptoms of MD on a visual-analog scale. The QoL was assessed with the help of The World Health Organization Quality of Life Brief Version (WHOQOL-BREF) before the start of a 4-week course of MD supplementation and after treatment.
Results. According to the MDQ results, the prevalence of DM was 79.4%, which exceeded the results of all other groups in the study. Women with MD had a higher incidence of viral infections (19.2% vs. 22.7%; p=0.028), vegetative-vascular dystonia (26.2% vs. 29.7%; p=0.0466) and osteochondrosis (42.9% vs. 46.8%; p=0.0453). A subgroup of participants with verified MD demonstrated significantly more pronounced symptoms, such as irritability (4.9±3.5 vs. 4.6±3.4 points in the general group; p=0.0437), sleep disorders (4.4±2.3 vs. 4.2±2.3 points; p=0.0491), back pain (3.9±2.0 vs. 3.7±2.0; p=0.0405), and increased fatigue (4.6±2.3 vs. 4.4±2.3 points; p=0.0444). After the end of the course of therapy with fixed dose combination of magnesium citrate and pyridoxine, the sum of MDQ scores decreased from 46.0±12.7 to 29.2±15.1 points (p<0.001) in combination with an increase in the plasma concentration of magnesium to 0.79±0.23 mmol/l; women's satisfaction with their physical, psychological, social well-being increased (from 21.1±4.5 to 26.2±3.5 points; from 24.8±4.9 to 28.1±4.4 points, and from 9.3±2.7 to 11.0±2.8 points, respectively; p<0.001); self-perception increased from 18.2±3.7 to 22.2±3.6 points. Thus, there was a significant decrease in the severity of MD and a significant improvement in QoL according to WHOQOL-BREF, which is important in the rehabilitation of such patients.
Conclusion. The profile of patients with MS and surgical menopause receiving MHT, including the period of recovery after radical surgical treatment of reproductive cancer, is characterized by MD and decreased QoL. It seems effective to introduce MD correction into the complex rehabilitation program of such patients. It is necessary to conduct further studies to improve the rehabilitation measures in this cohort of patients.
The flowers of Quararibea funebris tree are an important component of tejate, a traditional Mexican beverage. The flowers exhibited a high concentration of total polyphenolic compounds, total carotenoids, and vitamin C. UPLC analysis revealed the presence of salicylic acid, kaemferol-3-O-glucoside, trans-cinnamic acid, rutin, scopoletin, l-phenylalanine, 4-coumaric acid and quercetin-3-glucoside, among others metabolites. The flowers exhibited volatile compounds as isolongifolene, α-cedrene, 2,5,5-trimethyl-2,3,4,5,6,7-hexahydro-1H-2,4a-ethanonaphthalene, while that linoleic acid, palmitic acid, and linolenic acid were the major fatty acids present in the oil extract. Magnesium, potassium, and calcium were the minerals most abundant in the flowers. In addition the methanolic extract of the flowers exhibited antimicrobial properties against the tested pathogenic microbial strains. In conclusion, these results showed that the Q. funebris flowers not only have an aromatic and flavoring power for the Tejate beverage, but also contains compounds with antioxidant, antimicrobial, and nutraceutical potential, which helps to explain its therapeutic uses.
The unusual intrinsic properties of nanomaterials, such as small size and high surface-to-volume ratio, have invited their applications in various animal and human nutrition sectors. Since the recent past, there has been a tremendous surge in demand for animal-derived food due to the concomitant increase in the human population. The quantity and quality of animal-derived food are mainly dependent on the health and wellness of the livestock. Dietary mineral elements are well known to play an essential role in maintaining the livestock's nutrition. However, poor bioavailability of administered mineral elements leads to malnutrition and associated health issues in animals. Feeding nanoparticles to livestock has showed promising results including increased growth performance, immunity, reproduction ability, and quality animal products. This review provides a comprehensive discussion on the need for animal nutrition, major bottlenecks of the field, and the use of nanotechnologies as an alternative to the traditional pattern of mineral element supplementation. A significant emphasis has also been given to the possible approaches for developing nanominerals suitable for livestock nutrition. Availability of consumer market for nanotechnology-based food may drive this field to develop different strategies for food sensing, packaging, nutrition, and immunity booster.
The reported incidence of eclampsia is 1.6-10 per 10,000 deliveries in developed countries, where as it is 50-151 per 10,000 deliveries in developing countries. In addition, low resource countries have substantially higher rates of maternal and perinatal mortalities and morbidities. This disparity in incidence and pregnancy outcomes maybe related to universal access to prenatal care, early detection of preeclampsia, timely delivery, and availability of health care resources in developed as compared to developing countries. Because of its infrequency in developed countries, many obstetric providers and maternity units have minimal to no experience in acute management of eclampsia and its complications. Therefore, clear protocols for prevention of eclampsia in those with severe preeclampsia and acute treatment of eclamptic seizures at all levels of health care are required for better maternal and neonatal outcomes. Eclamptic seizure will occur in 2% of women with preeclampsia with severe features who are not receiving magnesium sulfate, and in less than 0.6% in those receiving magnesium. The pathogenesis of an eclamptic seizure is not well understood, however blood brain barrier (BBB) disruption with passage of fluid, ions and plasma protein into the brain parenchyma remains the leading theory. New data suggest that BBB permeability may increase by circulating factors found in preeclamptic women plasma such as vascular endothelial growth factor and placental growth factor. The management of an eclamptic seizure will include supportive care to prevent serious maternal injury, magnesium sulfate for prevention of recurrent seizures and promoting delivery. While routine imagining following eclamptic seizure is not recommended, the classic finding is referred to as posterior reversible encephalopathy syndrome (PRES). The majority of patients with PRES will show complete resolution of the imaging finding within 1-2 weeks, but routine imaging follow up is unnecessary unless there are findings of intracranial hemorrhage, infraction or ongoing neurologic deficit. Eclampsia is associated with increased risk for maternal mortality and morbidity such as placental abruption, disseminated intravascular coagulation, pulmonary edema, aspiration pneumonia, cardiopulmonary arrest and acute renal failure. Furthermore, a history of eclamptic seizure is may be related to long-term cardiovascular risk and cognitive difficulties related to memory and concentration years after the index pregnancy. Finally, limited data suggest that placental growth factor levels in preeclamptic women are superior to clinical markers in prediction of adverse pregnancy outcomes. This data may be extrapolated to prediction of eclampsia in future studies. This summary of available evidence provides data and expert opinion on possible pathogenesis of eclampsia, imagining findings, differential diagnosis, and stepwise approach regarding management of eclampsia prior to delivery and during the postpartum, as well as current recommendations for prevention of eclamptic seizure in women with preeclampsia.
Owing to hormonal changes, women experience various psychophysiological alterations over a wide age range, which may result in decreased quality of life as well as in increased risks of diseases, such as cardiovascular diseases. Although studies have been performed to research complementary methods, such as meditation, the research field still requires an adequate amount of studies for public health guidelines. This pilot cross-sectional study aims to investigate a potential association of meditation with menopausal symptoms and blood chemistry for healthy women. In this study, data of 65 healthy women (age range 25-67) including 33 meditation practitioners and 32 meditation-naïve controls were analyzed to compare the Menopausal Rating Scale scores and blood chemistry with 7 more dropouts in the blood chemistry. For blood chemistry, nine components including glucose (GLU) and high-density lipoprotein cholesterol (HDL) were measured. Two-way analysis of variance was performed by dividing the total participants into 2 groups: premenopausal and postmenopausal participants. Compared to the control group, the meditation group showed a trend of reductions in the Menopausal Rating Scale total score (P = .054) and its 2 subcomponents: depressive mood (P = .064) and irritability (P = .061). In HDL level, there was a significant interaction between group and menopausal state (P = .039) with following post hoc results: among the premenopausal participants, a significant increase in the meditation group compared to the control group (P = .005); among the control group, a significant increase in the postmenopausal compared to the premenopausal participants (P = .030). In GLU level, there was a mild interaction between group and menopausal state (P = .070) with following post hoc results: among the postmenopausal participants, a trend of increase in the control group compared to the meditation group (P = .081); among the control group, a significant increase in the postmenopausal compared to the premenopausal participants (P = .040). Our research suggests a potential association of practicing meditation with alleviations in menopausal symptoms and changes in blood chemistry, warranting further studies with a longitudinal study design and larger populations to understand the underlying causal relationships.
In this study, we aimed to systematically review the literature to evaluate the effects of magnesium (Mg) supplementation on blood pressure (BP) and obesity measure among patients with type 2 diabetes mellitus (T2DM). Major electronic databases of Web of Science, the Cochrane library, PubMed, and Scopus were searched completely from the inception until 15 October 2019 to identify randomized clinical trials (RCTs) pertaining to the topic of interest. All outcomes were pooled using a random-effects model and expressed as weighted mean differences (WMD) with 95% confidential intervals (CI). Heterogeneity, sensitivity analysis, and publication bias were also assessed using standard methods. The pooled analysis of five RCTs showed that Mg supplementation did not affect body weight (WMD: − 0.01 kg, 95% CI: − 0.36 to 0.33), BMI (WMD: − 0.07, 95% CI: − 0.18 to 0.04), and waist circumference (WMD: 0.12, 95% CI: − 1.24 to 1.48) in T2DM patients compared to the control groups of the patients who received placebo. However, pooling seven RCTs together showed significant reduction of systolic blood pressure (WMD: − 5.78 mmHg, 95% CI: − 11.37 to − 0.19) and diastolic blood pressure (WMD: − 2.50 mmHg, 95% CI: − 4.58 to − 0.41) in T2DM patients. Furthermore, subgroup analysis by dose of intervention, intervention duration, and type of intervention suggested that Mg supplementation for > 12 weeks, in doses higher than 300 mg/day or inorganic forms, could significantly decrease both systolic and diastolic BP in T2DM patients. Based on the findings, Mg supplementation has beneficial effects on BP in type 2 diabetes patients independent of body weight status. However, further investigations are needed to provide more reliable evidences.
Background:
Fetal programming during in utero life defines the set point of physiological and metabolic responses that lead into adulthood; events happening in "the first 1,000 days" (from conception to 2-years of age), play a role in the development of non-communicable diseases (NCDs). The infant gut microbiome is a highly dynamic organ, which is sensitive to maternal and environmental factors and is one of the elements driving intergenerational NCDs' transmission. The A.MA.MI (Alimentazione MAmma e bambino nei primi MIlle giorni) project aims at investigating the correlation between several factors, from conception to the first year of life, and infant gut microbiome composition. We described the study design of the A.MA.MI study and presented some preliminary results.
Methods:
A.MA.MI is a longitudinal, prospective, observational study conducted on a group of mother-infant pairs (n = 60) attending the Neonatal Unit, Fondazione IRCCS Policlinico San Matteo, Pavia (Italy). The study was planned to provide data collected at T0, T1, T2 and T3, respectively before discharge, 1,6 and 12 months after birth. Maternal and infant anthropometric measurements were assessed at each time. Other variables evaluated were: pre-pregnancy/gestational weight status (T0), maternal dietary habits/physical activity (T1-T3); infant medical history, type of feeding, antibiotics/probiotics/supplements use, environment exposures (e.g cigarette smoking, pets, environmental temperature) (T1-T3). Infant stool samples were planned to be collected at each time and analyzed using metagenomics 16S ribosomal RNA gene sequence-based methods.
Results:
Birth mode (cesarean section vs. vaginal delivery) and maternal pre pregnancy BMI (BMI < 25 Kg/m2 vs. BMI ≥ 25 Kg/m2), significant differences were found at genera and species levels (T0). Concerning type of feeding (breastfed vs. formula-fed), gut microbiota composition differed significantly at genus and species level (T1).
Conclusion:
These preliminary and explorative results confirmed that pre-pregnancy, mode of delivery and infant factors likely impact infant microbiota composition at different levels.

Background
Polycystic ovary syndrome (PCOS) is the most common endocrinopathy among reproductive age women. Although its cardinal manifestations include hyperandrogenism, oligo/anovulation, and/or polycystic ovarian morphology, PCOS women often display also notable metabolic comorbidities. An array of pathogenic mechanisms have been implicated in the etiology of this heterogeneous endocrine disorder; hyperandrogenism at various developmental periods is proposed as a major driver of the metabolic and reproductive perturbations associated with PCOS. However, the current understanding of the pathophysiology of PCOS-associated metabolic disease is incomplete, and therapeutic strategies used to manage this syndrome's metabolic complications remain limited.
Scope of review
This study is a systematic review of the potential etiopathogenic mechanisms of metabolic dysfunction frequently associated with PCOS, with special emphasis on the metabolic impact of androgen excess on different metabolic tissues and the brain. We also briefly summarize the therapeutic approaches currently available to manage metabolic perturbations linked to PCOS, highlighting current weaknesses and future directions.
Major conclusions
Androgen excess plays a prominent role in the development of metabolic disturbances associated with PCOS, with a discernible impact on key peripheral metabolic tissues, including the adipose, liver, pancreas, and muscle, and very prominently the brain, contributing to the constellation of metabolic complications of PCOS, from obesity to insulin resistance. However, the current understanding of the pathogenic roles of hyperandrogenism in metabolic dysfunction of PCOS and the underlying mechanisms remain largely incomplete. In addition, the development of more efficient, even personalized therapeutic strategies for the metabolic management of PCOS patients persists as an unmet need that will certainly benefit from a better comprehension of the molecular basis of this heterogeneous syndrome.
Polycystic ovary syndrome (PCOS) is a common infertility disorder affecting a significant proportion of the global population. It is the main cause of anovulatory infertility in women and is the most common endocrinopathy affecting reproductive-aged women, with a prevalence of 8–13% depending on the criteria used and population studied. The disease is multifactorial and complex and, therefore, often difficult to diagnose due to overlapping symptoms. Multiple etiological factors have been implicated in PCOS. Due to the complex pathophysiology involving multiple pathways and proteins, single genetic diagnostic tests cannot be determined. Progress has been achieved in the management and diagnosis of PCOS; however, not much is known about the molecular players and signaling pathways underlying it. Conclusively PCOS is a polygenic and multifactorial syndromic disorder. Many genes have been associated with PCOS, which affect fertility either directly or indirectly. However, studies conducted on PCOS patients from multiple families failed to find a fully penetrant variant(s). The present study was designed to review the current genetic understanding of the disease. In the present review, we have discussed the clinical spectrum, the genetics, and the variants identified as being associated with PCOS. The mechanisms by which variants in the genes confer risk to PCOS and the nature of the physical and genetic interaction between the genetic elements underlying PCOS remain to be determined. Elucidation of genetic players and cellular pathways underlying PCOS will certainly increase our understanding of the pathophysiology of this syndrome. The study also discusses the current status of the treatment modalities for PCOS, which is important to find new ways of treatment.
Polycystic ovary syndrome (PCOS) affects ∼1 in 10 women worldwide. Hypomagnesemia may worsen insulin resistance (IR) due to the role magnesium (Mg) plays in glucose metabolism. This review explores the relation between serum Mg and IR among women with PCOS. A review of primary research focusing on both serum Mg and women with PCOS was conducted from 2011 to 2019. Studies reviewed included human subjects, written in the English language, and limited to community-dwelling women aged ≥18 y. A total of 7 articles were reviewed. The findings from 4 epidemiological analytic studies evaluating serum Mg status suggest there may be a relation between serum Mg concentrations and IR among women with PCOS. However, among the 3 experimental trials, Mg supplementation inconsistently impacted IR among women with PCOS. Women with PCOS are more likely to underconsume Mg-rich foods and have a greater likelihood of lower serum Mg concentrations. Although it remains unclear if dietary Mg and/or supplementation should be a nutritional strategy for all women with PCOS, current research indicates an association between adequate Mg status and improved IR. Further research evaluating dietary interventions and supplementation is warranted.
Objective:
Our initial understanding of the menopause transition (MT) has been framed by clinical samples of women seeking treatment rather than by population-based studies. The Study of Women's Health Across the Nation (SWAN) initiated in 1996 with an overall goal to define the MT, to characterize its biological and psychosocial antecedents and sequelae in an ethnically and racially diverse sample of midlife women.
Methods:
This review summarizes the central findings of SWAN to date that can inform women and their healthcare providers about the impact of the MT and midlife aging on overall health and well-being.
Results:
SWAN characterized changes in reproductive axis and menstrual cycle patterns that informed the development of the reproductive aging staging system Staging of Reproductive Aging Workshop+10; MT-related symptoms and mental health (vasomotor symptoms, sleep complaints, psychological symptoms, cognitive performance, and urogenital and sexual health); and physiological systems and functions (cardiovascular and cardiometabolic health, bone health, physical function performance) that are influenced by the MT. SWAN demonstrated substantial interrelations among these changes and significant racial/ethnic differences in the rate and magnitude of change in multiple health indictors in midlife women. The findings point to midlife as a critical stage for adopting healthy behavior and preventive strategies.
Conclusions:
Over the past 23 years, SWAN has advanced our understanding of the impact of the MT and midlife aging on health and well-being in women. SWAN will be instrumental to determine whether MT-related changes during midlife are related to unfavorable health and well-being in early old age.
Polycystic ovary syndrome (PCOS) is a common female condition typified by reproductive, hyperandrogenic, and metabolic features. Polycystic ovary syndrome is a genetic condition, exacerbated by obesity. There is a close link between obesity and PCOS based on epidemiological data, and more recently corroborated through genetic studies. There are many mechanisms mediating the effects of weight-gain and obesity on the development of PCOS. The metabolic effects of insulin resistance and steroidogenic and reproductive effects of hyperinsulinaemia are important mechanisms. Adipokine production by subcutaneous and visceral fat appears to play a part in metabolic function. However, given the complexity of PCOS pathogenesis, it is important also to consider possible effects of PCOS on further weight-gain, or at least on hampering attempts at weight-loss and maintenance through lifestyle changes. Possible mediators of these effects include changes in energy expenditure, mental ill health, or physical inactivity. In this brief review, we discuss the main mechanisms that underlie the association between obesity and PCOS, from divergent perspectives of weight-gain contributing to development of PCOS and vice versa. We also consider novel management options for women with obesity and PCOS.
Background:
Inflammation and insulin resistance play crucial roles in the development of type 2 diabetes mellitus (T2DM). We aim to examine the temporal relationship between high-sensitivity C-reactive protein (hsCRP) and insulin resistance in non-diabetic adults and their joint effect on the development of hyperglycemia.
Methods:
The longitudinal cohort from the Bogalusa Heart Study consisted of 509 non-diabetic adults (360 whites and 149 blacks, mean age = 42.8 years at follow-up) who had hsCRP, fasting glucose and insulin measured twice at baseline and follow-up over 6.8 years. Cross-lagged panel model was used to examine the temporal relationship between hsCRP and homeostasis model assessment for insulin resistance (HOMA-IR). Information on incident T2DM was collected in a survey in 6.1 years after the follow-up survey.
Results:
After adjusting for race, sex, age, body mass index, smoking, alcohol drinking and follow-up years, the path coefficient from baseline hsCRP to follow-up HOMA-IR (β2 = 0.105, p = 0.009) was significant and greater than the path from baseline HOMA-IR to follow-up hsCRP (β1 = 0.005, p = 0.903), with p = 0.011 for the difference between β1 and β2. This one-directional path from baseline hsCRP to follow-up HOMA-IR was significant in the hyperglycemia group but not in the normoglycemia group. In addition, participants with high levels of baseline hsCRP and follow-up HOMA-IR had greater risks of T2DM (odds ratio, OR = 2.38, p = 0.035), pre-T2DM (OR = 2.27, p = 0.006) and hyperglycemia (OR = 2.18, p = 0.003) than those with low-low levels.
Conclusions:
These findings suggest that elevated hsCRP is associated with future insulin resistance in non-diabetic adults, and their joint effect is predictive of the development of T2DM.
Objectives:
The ratio of calcium to magnesium (Ca: Mg) intake has gained immense attention in recent years, since a ratio above 2:1 has been associated with increased risk of metabolic, inflammatory and cardiovascular disorders. The objective of this study was to assess Ca: Mg ratios across age groups and to determine the relationship between Ca: Mg ratios and markers of inflammation.
Methods:
Adult men and women, 18 to 60 years of age, completed a demographic form, a magnesium food frequency questionnaire and a calcium food frequency questionnaire. In a subset of individuals, biochemical assays were completed for inflammation markers such as interleukin-6 (IL-6), monocyte chemoattractant protein-1 (MCP-1), C-reactive protein (CRP) and matrix metallopeptidase 9 (MMP-9). Means, standard deviations, medians and interquartile ranges were calculated, and Pearson's correlations were conducted to determine the relationship between Ca: Mg ratio and markers of inflammation.
Results:
Fifty-six adults were included in this analysis, and were categorized into four age categories: 18 to 29 years, 30 to 39 years, 40 to 49 years and 50 to 59 years. On average, participants were 28.87 ± 10.16 years of age, with a body mass index of 24.54 ± 3.72 kg/m2. Mean magnesium intake, calcium intake and Ca: Mg ratio for each age group were: 249.08 mg, 763.89 mg and 3.37 for the 18-29 years group, 226.59 mg, 730.50 mg and 3.58 for the 30 to 39 years group, 252.63 mg, 731.29 mg and 3.19 for the 40 to 49 years group and 286.03 mg, 595.03 mg and 2.79 mg for the 50 to 59 years group. All study groups had lower magnesium and calcium intakes compared to the Recommended Daily Allowances for these nutrients; however, the Ca: Mg ratio was higher than the optimal ratio of 2:1 in all age groups. In a subset, Ca: Mg ratio was significantly associated with IL-6 (r = 0.626, P = 0.017).
Conclusions:
All age groups had a high Ca: Mg ratio above the optimal 2:1 ratio and in a subset of participants, a higher Ca: Mg ratio was associated with greater inflammation. Interventional studies should target lowering the Ca: Mg ratio in the diet and assess the effect of lowering Ca: Mg ratio on changes in metabolic markers.

A number of studies have assessed the association between serum magnesium (Mg) and premenstrual syndrome (PMS) in different population, but the findings have been inconclusive. Herein, we systematically reviewed available observational studies to elucidate the overall relationship between Mg and PMS. PubMed, Cochrane’s library, ScienceDirect, Scopus, Google Scholar, and ISI web of science databases were searched for all available literature until January 2019 for studies evaluating the association between Mg and PMS. The Newcastle-Ottawa Quality Assessment Scale was used to assess the quality of observational studies. A total of 13 studies out of 196 met our inclusion criteria and were included in our systematic review and meta-analysis. There were no associations between serum magnesium and PMS (WMD − 0.04; 95% CI, − 0.14 to 0.06; P = 0.46) during follicular or serum/erythrocyte magnesium (WMD − 0.37; 95% CI, − 1.01 to 0.27; P = 0.25)/(WMD − 0.04; 95% CI, − 0.10 to 0.03; P = 0.26) and during luteal phase except for the sub-group of studies done outside of the US in which recent association became significant and means that serum Mg is lower in PMS subjects. According to what have been discussed, although our study did not show any significant association between serum/erythrocyte Mg and PMS except for serum Mg in luteal phase in the sub-group of studies done outside of the USA, heterogeneity between studies should be taken into accounts when interpreting these results. Additional well-designed clinical trials should be considered in future research to develop firm conclusions on the efficacy of magnesium on PMS.

We evaluated the associations of the ages at menarche and menopause with blood pressure (BP) and hypertension using the baseline data of 7893 women from the China Health and Retirement Longitudinal Study, a nationally representative survey among Chinese adults aged ≥45 years. Multivariate linear and logistic regression analyses were performed to evaluate the associations of the ages at menarche and men`opause with BP and hypertension, respectively. Nonlinear associations were evaluated using spline analyses. After controlling for age, education, marital status, living areas, smoking, drinking, and medication use if necessary, an early onset of menarche by 1 year was associated with a 6% (95% confidence interval [CI]: 3–9%) higher odds of hypertension and 0.82 mm Hg (P < 0.001) and 0.41 mm Hg (P < 0.001) higher systolic and diastolic BP, respectively. When further controlling for the body mass index (BMI), blood glucose, and lipids, the associations were still significant. Spline analyses did not support U-shaped relationships between menarche age and hypertension risk (P = 0.35), systolic BP (P = 0.60), or diastolic BP (P = 0.70). When stratified by location of residence, menarche age was only associated with BP and hypertension among women living in rural areas. The age of menopause was positively associated with hypertension (odds ratio [OR] = 1.02 per year delay of menopause, 95% CI: 1.01–1.03). However, when further controlling for BMI, such an association no longer existed (OR = 1.01, P = 0.32). These findings indicated that the associations of menarche age with BP and hypertension may be modified by factors related to the area of residence in China, and the association between menopause age and hypertension was driven by BMI.
Background:
Previous in vitro and in vivo studies indicate that enzymes that synthesize and metabolize vitamin D are magnesium dependent. Recent observational studies found that magnesium intake significantly interacted with vitamin D in relation to vitamin D status and risk of mortality. According to NHANES, 79% of US adults do not meet their Recommended Dietary Allowance of magnesium.
Objectives:
The aim of this study was to test the hypothesis that magnesium supplementation differentially affects vitamin D metabolism dependent on baseline 25-hydroxyvitamin D [25(OH)D] concentration.
Methods:
The study included 180 participants aged 40-85 y and is a National Cancer Institute independently funded ancillary study, nested within the Personalized Prevention of Colorectal Cancer Trial (PPCCT), which enrolled 250 participants. The PPCCT is a double-blind 2 × 2 factorial randomized controlled trial conducted in the Vanderbilt University Medical Center. Doses for both magnesium and placebo were customized based on baseline dietary intakes. Subjects were randomly assigned to treatments using a permuted-block randomization algorithm. Changes in plasma 25-hydroxyvitamin D3 [25(OH)D3], 25-hydroxyvitamin D2 [25(OH)D2], 1,25-dihydroxyvitamin D3, 1,25-dihydroxyvitamin D2, and 24,25-dihydroxyvitamin D3 [24,25(OH)2D3] were measured by liquid chromatography-mass spectrometry.
Results:
The relations between magnesium treatment and plasma concentrations of 25(OH)D3, 25(OH)D2, and 24,25(OH)2D3 were significantly different dependent on the baseline concentrations of 25(OH)D, and significant interactions persisted after Bonferroni corrections. Magnesium supplementation increased the 25(OH)D3 concentration when baseline 25(OH)D concentrations were close to 30 ng/mL, but decreased it when baseline 25(OH)D was higher (from ∼30 to 50 ng/mL). Magnesium treatment significantly affected 24,25(OH)2D3 concentration when baseline 25(OH)D concentration was 50 ng/mL but not 30 ng/mL. On the other hand, magnesium treatment increased 25(OH)D2 as baseline 25(OH)D increased.
Conclusion:
Our findings suggest that optimal magnesium status may be important for optimizing 25(OH)D status. This trial was registered at clinicaltrials.gov as NCT03265483.
Synergistic approach of magnesium and vitamin E may benefit clinical symptoms of patients with polycystic ovary syndrome (PCOS) through improving their metabolic profiles and reducing oxidative stress and inflammation. This study was designed to determine the effects of magnesium and vitamin E co-supplementation on hormonal status and biomarkers of inflammation and oxidative stress in women with PCOS. This randomized, double-blind, placebo-controlled trial was conducted among 60 women with PCOS, aged 18–40 years old. Participants were randomly divided into two groups to take 250 mg/day magnesium plus 400 mg/day vitamin E supplements or placebo (n = 30 each group) for 12 weeks. Fasting blood samples were taken at baseline and after the 12-week intervention to quantify related variables. Magnesium and vitamin E co-supplementation resulted in a significant reduction in hirsutism (β − 0.37; 95% CI, − 0.70, − 0.05; P = 0.02) and serum high-sensitivity C-reactive protein (hs-CRP) (β − 0.67 mg/L; 95% CI, − 1.20, − 0.14; P = 0.01), and a significant increase in plasma nitric oxide (NO) (β 3.40 μmol/L; 95% CI, 1.46, 5.35; P = 0.001) and total antioxidant capacity (TAC) levels (β 66.32 mmol/L; 95% CI, 43.80, 88.84; P < 0.001). Overall, magnesium and vitamin E co-supplementation for 12 weeks may benefit women with PCOS on hirsutism, serum hs-CRP, plasma NO, and TAC levels.

Magnesium is essential for maintaining normal cellular and organ function. In-adequate magnesium balance is associated with various disorders, such as skeletal deformities, cardiovascular diseases, and metabolic syndrome. Unfortunately, routinely measured serum magnesium levels do not always reflect total body magnesium status. Thus, normal blood magnesium levels eclipse the wide-spread magnesium deficiency. Other magnesium measuring methods, including the magnesium loading test, may provide more accurate reflections of total body magnesium status and thus improve identification of magnesium-deficient individuals, and prevent magnesium deficiency related complications.
Background: The present study was planned to study the role of Mg in preeclampsia and its correlation with dietary intake of proteins and calories by analyzing serum Mg at 20 weeks, delivery, and cord blood Mg levels. Methods: The study was conducted in 102 pregnant women aged 17–36 years attending the outpatient department (OPD) before 20 weeks of gestation. The study samples were drawn twice: once before 20 weeks during visit in the OPD and second within 1 h of childbirth. Serum was analyzed for Mg levels using spectrophotometric method. Furthermore, thyroid-stimulating hormone and glucose challenge test were done as per the standard methods. Results: In normal pregnant women, the mean serum Mg level at
Background: Obesity is a complex, multifactorial condition in which excess body weight may put a female at risk of serious health problems such as hypertension, dyslipidemia, diabetes mellitus and cardiovascular diseases. Magnesium deficiency is reported to be associated with obesity in children and adolescents. An inverse relationship has been reported between serum magnesium and estrogen levels in women. It is not known whether magnesium deficiency may have a role in genesis of obesity in women after menopause. Therefore, the present study was planned to compare serum magnesium levels in obese and non-obese postmenopausal women and to find out the relationship, if any, between serum magnesium levels and obesity.Methods: This cross-sectional study was conducted in the department of Biochemistry at National Institute of Medical Sciences and Research, Jaipur, Rajasthan on fifty subjects over a period of six months. Twenty-five obese postmenopausal women (BMI ≥ 30) having their final menstrual period at least one year prior to the study were taken as the study group and twenty-five non-obese (BMI ≤ 22.9) post-menopausal women were taken as control group. All subjects were asked to give detailed dietary history using Food Frequency Questionnaire (FFQ). Venous blood samples were collected after an overnight fast for estimation of serum total magnesium in all subjects.Results: Obese postmenopausal women had significantly higher weight (78.36±0.064kg) and BMI (32.68±1.7kg/mt2) compared to non-obese postmenopausal women (wt. 54.72±4.80kg and BMI 21.75±1.68kg/mt2). The mean±SD serum magnesium concentration found in the obese postmenopausal women was 1.40±0.45mg/dl as compared to 2.03±0.49 mg/dl in the non-obese group. Pearson’s correlation analysis showed a significant (r = -0.9) negative correlation between BMI and serum magnesium in postmenopausal women.Conclusions: Serum magnesium was lower in obese postmenopausal women as compared to that in non-obese postmenopausal women. Serum magnesium was negatively correlated with BMI. Magnesium supplementation may be useful in prevention of obesity after menopause.
Vitamin B6 is one of the most central molecules in cells of living organisms. It is a critical co-factor for a diverse range of biochemical reactions that regulate basic cellular metabolism, which impact overall physiology. In the last several years, major progress has been accomplished on various aspects of vitamin B6 biology. Consequently, this review goes beyond the classical role of vitamin B6 as a cofactor to highlight new structural and regulatory information that further defines how the vitamin is synthesized and controlled in the cell. We also discuss broader applications of the vitamin related to human health, pathogen resistance, and abiotic stress tolerance. Overall, the information assembled shall provide helpful insight on top of what is currently known about the vitamin, along with addressing currently open questions in the field to highlight possible approaches vitamin B6 research may take in the future.
Background:
Magnesium and vitamin E are known to exert multiple beneficial effects, such as anti-glycemic and anti-lipidemic properties. The aim of this study was to determine the effects of magnesium and vitamin E co-supplementation on metabolic status of women with gestational diabetes (GDM).
Methods:
This randomized, double-blinded, placebo-controlled trial was conducted among 60 subjects diagnosed with GDM, aged 18-40 years. Subjects were randomly allocated into two groups to receive 250 mg/day magnesium oxide plus 400 IU/day vitamin E supplements or placebo (n = 30 each group) for 6 weeks. Participants' blood samples were taken to determine their metabolic profiles.
Results:
Subjects who received magnesium plus vitamin E supplements had significantly lower fasting plasma glucose (β - 5.20 mg/dL; 95% CI, - 7.88, - 2.52; P = 0.002), serum insulin levels (β - 2.93 μIU/mL; 95% CI, - 5.68, - 0.18; P = 0.02) and homeostasis model of assessment-insulin resistance (β - 0.78; 95% CI, - 1.42, - 0.14; P = 0.01), and higher quantitative insulin sensitivity check index (β 0.01; 95% CI, 0.005, 0.02; P = 0.002) compared with placebo. In addition, magnesium plus vitamin E supplementation resulted in a significant reduction in serum triglycerides (β - 50.31 mg/dL; 95% CI, - 67.58, - 33.04; P < 0.001), VLDL- (β - 10.06 mg/dL; 95% CI, - 13.51, - 6.60; P < 0.001), total- (β - 26.10 mg/dL; 95% CI, - 41.88, - 10.33; P = 0.004), LDL- (β - 15.20 mg/dL; 95% CI, - 29.50, - 0.91; P = 0.03) and total-/HDL-cholesterol ratio (β - 0.46; 95% CI, - 0.72, - 0.19; P < 0.001) compared with placebo. Magnesium and vitamin E co-supplementation did not affect HDL-cholesterol levels.
Conclusions:
Overall, magnesium and vitamin E co-supplementation for 6 weeks in women with GDM significantly improved glycemic control and lipid profiles, except for HDL-cholesterol levels.

Introduction: The aim of the study was to undertake a systematic review and meta-analysis of prospective studies to determine the effect of magnesium (Mg) supplementation on C-reactive protein (CRP). Design: Systematic review and meta-analysis of randomised controlled trials (RCTs).
Material and methods: Data sources: PubMed-Medline, Web of Science, Co-chrane Database, and Google Scholar databases were searched (up until December 2016). Eligibility criteria: Randomized controlled trials evaluating the impact of Mg supplementation on CRP. We used random effects models meta-analysis for quantitative data synthesis. For sensitivity analysis was used the leave-one-out method. Heterogeneity was quantitatively assessed using the I 2 index. Main outcome: Level of CRP after Mg supplementation.
Results: From a total of 96 entries identified via searches, eight studies were included in the final selection. The meta-analysis indicated a significant reduction in serum CRP concentrations following Mg supplementation (weighted mean difference (WMD)-1.33 mg/l; 95% CI:-2.63 to-0.02, het-erogeneity p < 0.123; I 2 = 29.1%). The WMD for interleukin 6 was-0.16 pg/dl (95% CI:-3.52 to 3.26, heterogeneity p = 0.802; I 2 = 2.3%), and 0.61 mg/dl (95% CI:-2.72 to 1.48, p = 0.182, heterogeneity p = 0.742; I 2 = 6.1%) for fasting blood glucose. These findings were robust in sensitivity analyses. Random-effects meta-regression revealed that changes in serum CRP levels were independent of the dosage of Mg supplementation (slope:-0.004; 95% CI:-0.03, 0.02; p = 0.720) or duration of follow-up (slope:-0.06; 95% CI:-0.37, 0.24; p = 0.681).
Conclusions: This meta-analysis suggests that Mg supplementation significantly reduces serum CRP level. RCTs with a larger sample size and a longer follow-up period should be considered for future investigations to give an unequivocal answer.
Background
Magnesium (Mg ²⁺ ) has received considerable attention with regards to its potential role in the pathophysiology of the mood disorders, but the available evidence seems inconclusive.
Aims
To review and quantitatively summarise the human literature on Mg ²⁺ intake and Mg ²⁺ blood levels in the mood disorders and the effects of Mg ²⁺ supplements on mood.
Method
Systematic review and meta-analyses.
Results
Adherence to a Mg ²⁺ -rich diet was negatively associated with depression in cross-sectional (odds ratio = 0.66) but not in prospective studies. Mg ²⁺ levels in bodily fluids were on average higher in patients with a mood disorder (Hedge's g = 0.19), but only in patients treated with antidepressants and/or mood stabilisers. There was no evident association between Mg ²⁺ levels and symptom severity. Mg ²⁺ supplementation was associated with a decline in depressive symptoms in uncontrolled ( g = −1.60) but not in placebo-controlled trials ( g = −0.21).
Conclusion
Our results provide little evidence for the involvement of Mg ²⁺ in the mood disorders.

Arterial hypertension is a disease with a complex pathogenesis. Despite considerable knowledge about this socially significant disease, the role of magnesium deficiency (MgD) as a risk factor is not fully understood. Magnesium is a natural calcium antagonist. It potentiates the production of local vasodilator mediators (prostacyclin and nitric oxide) and alters vascular responses to a variety of vasoactive substances (endothelin-1, angiotensin II, and catecholamines). MgD stimulates the production of aldosterone and potentiates vascular inflammatory response, while expression/activity of various antioxidant enzymes (glutathione peroxidase, superoxide dismutase, and catalase) and the levels of important antioxidants (vitamin C, vitamin E, and selenium) are decreased. Magnesium balances the effects of catecholamines in acute and chronic stress. MgD may be associated with the development of insulin resistance, hyperglycemia, and changes in lipid metabolism, which enhance atherosclerotic changes and arterial stiffness. Magnesium regulates collagen and elastin turnover in the vascular wall and matrix metalloproteinase activity. Magnesium helps to protect the elastic fibers from calcium deposition and maintains the elasticity of the vessels. Considering the numerous positive effects on a number of mechanisms related to arterial hypertension, consuming a healthy diet that provides the recommended amount of magnesium can be an appropriate strategy for helping control blood pressure.
Magnesium is the fourth most abundant cation in the body. It has several functions in the human body including its role as a cofactor for more than 300 enzymatic reactions. Several studies have shown that hypomagnesemia is a common electrolyte derangement in clinical setting especially in patients admitted to intensive care unit where it has been found to be associated with increase mortality and hospital stay. Hypomagnesemia can be caused by a wide range of inherited and acquired diseases. It can also be a side effect of several medications. Many studies have reported that reduced levels of magnesium are associated with a wide range of chronic diseases. Magnesium can play important therapeutic and preventive role in several conditions such as diabetes, osteoporosis, bronchial asthma, preeclampsia, migraine, and cardiovascular diseases. This review is aimed at comprehensively collating the current available published evidence and clinical correlates of magnesium disorders.
Nutrients usually act in a coordinated manner in the body. Intestinal absorption and subsequent metabolism of a particular nutrient, to a certain extent, is dependent on the availability of other nutrients. Magnesium and vitamin D are 2 essential nutrients that are necessary for the physiologic functions of various organs. Magnesium assists in the activation of vitamin D, which helps regulate calcium and phosphate homeostasis to influence the growth and maintenance of bones. All of the enzymes that metabolize vitamin D seem to require magnesium, which acts as a cofactor in the enzymatic reactions in the liver and kidneys. Deficiency in either of these nutrients is reported to be associated with various disorders, such as skeletal deformities, cardiovascular diseases, and metabolic syndrome. It is therefore essential to ensure that the recommended amount of magnesium is consumed to obtain the optimal benefits of vitamin D.
Objective:
We investigated the effects of magnesium supplementation on glucose tolerance, insulin sensitivity, oxidative stress as well as the concentration of insulin receptor and glucose transporter-4 in streptozotocin-nicotinamide induced type-2 diabetic (T2D) rats.
Methods:
Rats were divided into four groups designated as: 1) control (CTR); 2) diabetic untreated (DU); 3) diabetic treated with 1 mg of Mg/kg diet (Mg1-D); and 4) diabetic treated with 2 mg of Mg/kg diet (Mg2-D). T2D was induced with a single intraperitoneal (i.p.) injection of freshly prepared streptozotocin (55 mg/kg) aft er an initial i.p. injection of nicotinamide (120 mg/kg). Glucose tolerance, insulin sensitivity, lipid profile, malondialdehyde (MAD) and glutathione content, insulin receptors (INSR) and glucose transporter-4 (GLUT4), fasting insulin and glucose levels were measured, and insulin resistance index was calculated using the homeostatic model assessment of insulin resistance (HOMA-IR).
Results:
Magnesium supplementation improved glucose tolerance and lowered blood glucose levels almost to the normal range. We also recorded a noticeable increase in insulin sensitivity in Mg-D groups when compared with DU rats. Lipid perturbations associated T2D were significantly attenuated by magnesium supplementation. Fasting glucose level was comparable to control values in the Mg-D groups while the HOMA-IR index was significantly lower compared with the DU rats. Magnesium reduced MDA but increased glutathione concentrations compared with DU group. Moreover, INSR and GLUT4 levels were elevated following magnesium supplementation in T2D rats.
Conclusion:
These findings demonstrate that magnesium may mediate effective metabolic control by stimulating the antioxidant defense, and increased levels of INSR and GLUT4 in diabetic rats.
Because serum magnesium does not reflect intracellular magnesium, the latter making up more than 99% of total body magnesium, most cases of magnesium deficiency are undiagnosed. Furthermore, because of chronic diseases, medications, decreases in food crop magnesium contents, and the availability of refined and processed foods, the vast majority of people in modern societies are at risk for magnesium deficiency. Certain individuals will need to supplement with magnesium in order to prevent suboptimal magnesium deficiency, especially if trying to obtain an optimal magnesium status to prevent chronic disease. Subclinical magnesium deficiency increases the risk of numerous types of cardiovascular disease, costs nations around the world an incalculable amount of healthcare costs and suffering, and should be considered a public health crisis. That an easy, cost-effective strategy exists to prevent and treat subclinical magnesium deficiency should provide an urgent call to action.
The scientific literature provides extensive evidence of widespread magnesium deficiency and the potential need for magnesium repletion in diverse medical conditions. Magnesium is an essential element required as a cofactor for over 300 enzymatic reactions and is thus necessary for the biochemical functioning of numerous metabolic pathways. Inadequate magnesium status may impair biochemical processes dependent on sufficiency of this element. Emerging evidence confirms that nearly two-thirds of the population in the western world is not achieving the recommended daily allowance for magnesium, a deficiency problem contributing to various health conditions. This review assesses available medical and scientific literature on health issues related to magnesium. A traditional integrated review format was utilized for this study. Level I evidence supports the use of magnesium in the prevention and treatment of many common health conditions including migraine headache, metabolic syndrome, diabetes, hyperlipidemia, asthma, premenstrual syndrome, preeclampsia, and various cardiac arrhythmias. Magnesium may also be considered for prevention of renal calculi and cataract formation, as an adjunct or treatment for depression, and as a therapeutic intervention for many other health-related disorders. In clinical practice, optimizing magnesium status through diet and supplementation appears to be a safe, useful, and well-documented therapy for several medical conditions.
Although >50% of U.S. adults use dietary supplements, little information is available on the impact of supplement use frequency on nutrient intakes and deficiencies. Based on nationally representative data in 10,698 adults from the National Health and Nutrition Examination Surveys (NHANES) 2009 to 2012, assessments were made of intakes from food alone versus food plus multi-vitamin/multi-mineral supplements (MVMS) of 17 nutrients with an Estimated Average Requirement (EAR) and a Tolerable Upper Intake Level (UL), and of the status of five nutrients with recognized biomarkers of deficiency. Compared to food alone, MVMS use at any frequency was associated with a lower prevalence of inadequacy (p < 0.01) for 15/17 nutrients examined and an increased prevalence of intakes >UL for 7 nutrients, but the latter was ≤4% for any nutrient. Except for calcium, magnesium, and vitamin D, most frequent MVMS use (≥21 days/30 days) virtually eliminated inadequacies of the nutrients examined, and was associated with significantly lower odds ratios of deficiency for the examined nutrient biomarkers except for iron. In conclusion, among U.S. adults, MVMS use is associated with decreased micronutrient inadequacies, intakes slightly exceeding the UL for a few nutrients, and a lower risk of nutrient deficiencies.
The prevalence of PCOS was investigated in many studies in different continents. However, there is no established prevalence of PCOS for distinct ethnic groups. In the current analysis, we conducted searches in PubMed, The Cochrane Library, EMBASE, CINAHL up to Jan. 2017 to identify studies reporting prevalence of PCOS in the general female population. Forty-two studies were identified, with 13 eligible for evidence synthesis. The prevalence among different ethnicity was estimated using random effect modelling. Our results suggested the lowest prevalence in Chinese women(2003 Rotterdam criterion: 5.6% 95% interval: 4.4-7.3%), and then in an ascending order for Caucasians (1990 NIH criterion: 5.5% 95% interval: 4.8-6.3%), Middle Eastern (1990 NIH 6.1% 95% interval: 5.3-7.1%; 2003 Rotterdam 16.0% 95% interval: 13.8-18.6%; 2006 AES 12.6% 95% interval: 11.3-14.2%), and Black women (1990 NIH: 6.1% 95% interval: 5.3-7.1%).There is variation in prevalence of PCOS under different diagnostic criteria and across ethnic groups. This emphasises the need for ethnicity-specific guidelines for PCOS to prevent under- or over-diagnosis of the condition given that under-diagnosis may lead to rapid conversion of metabolic disorders for patients whereas over-diagnosis may exert negative psychological effects on patients which worsens the major symptoms of PCOS.
Data on the effects of magnesium-zinc-calcium-vitamin D co-supplementation on hormonal profiles, biomarkers of inflammation, and oxidative stress among women with polycystic ovary syndrome (PCOS) are scarce. The objective of this study was to assess the effects of magnesium-zinc-calcium-vitamin D co-supplementation on hormonal profiles, biomarkers of inflammation, and oxidative stress in women with PCOS. Sixty PCOS women were randomized into two groups and treated with 100 mg magnesium, 4 mg zinc, 400 mg calcium plus 200 IU vitamin D supplements (n = 30), or placebo (n = 30) twice a day for 12 weeks. Hormonal profiles, biomarkers of inflammation, and oxidative stress were assessed at baseline and at end-of-treatment. After the 12-week intervention, compared with the placebo, magnesium-zinc-calcium-vitamin D co-supplementation resulted in significant reductions in hirsutism (−2.4 ± 1.2 vs. −0.1 ± 0.4, P < 0.001), serum high sensitivity C-reactive protein (−0.7 ± 0.8 vs. +0.2 ± 1.8 mg/L, P < 0.001), and plasma malondialdehyde (−0.4 ± 0.3 vs. +0.2 ± 1.0 μmol/L, P = 0.01), and a significant increase in plasma total antioxidant capacity concentrations (+46.6 ± 66.5 vs. −7.7 ± 130.1 mmol/L, P = 0.04). We failed to find any significant effect of magnesium-zinc-calcium-vitamin D co-supplementation on free androgen index, and other biomarkers of inflammation and oxidative stress. Overall, magnesium-zinc-calcium-vitamin D co-supplementation for 12 weeks among PCOS women had beneficial effects on hormonal profiles, biomarkers of inflammation, and oxidative stress.
Background:
Many women report gaining weight as they transition through menopause. For most, the weight gain is modest and can be reduced with a conscious effort to limit energy intake and increase energy expenditure. However, many women who are already overweight and obese will gain more weight as they approach menopause.
Objective:
The aims of this paper are to explain the reasons for menopausal weight gain and to detail a method for achieving and sustaining a substantial weight loss.
Discussion:
Weight gain during menopause is predominantly due to a reduction in spontaneous activity. For women who are lean, advice about controlling energy intake and increasing physical activity may be all that is required to prevent weight gain. For women who are overweight and obese rapid weight loss is best achieved with the help of a very low energy diet. This must be followed by lifelong behaviour modification with or without the help of hunger-suppressing pharmacotherapy.
Background:
Polycystic ovary syndrome (PCOS) is a common reproductive disorder associated with metabolic disturbances including obesity, insulin resistance, and diabetes mellitus. Here we investigate whether changes in the metabolic profile of PCOS women are driven by increased tendency to obesity or are specific features of PCOS related to increased testosterone levels.
Design and methods:
We conducted an NMR metabolomics association study of PCOS cases (n=145) and controls (n=687) nested in a population-based birth cohort (n=3,127). Subjects were 31 years old at examination. The main analyses were adjusted for waist circumference (WC) as a proxy measure of central obesity. Subsequently, metabolite concentrations were compared between cases and controls within pre-defined WC strata. On each stratum, additional metabolomics association analyses with testosterone levels were conducted separately among cases and controls.
Results:
Overall, women with PCOS showed more adverse metabolite profiles than the controls. Four lipid fractions in different subclasses of very low density lipoprotein (VLDL) were associated with PCOS, after adjusting for WC and correction for multiple testing (P<0.002). In stratified analysis the PCOS women within large WC strata (≥98 cm) had significantly lower high density lipoprotein (HDL) levels, ApoA1 and albumin values compared to the controls. Testosterone levels were significantly associated with VLDL and serum lipids in PCOS cases with large WC but not in the controls. The higher testosterone levels, adjusted for WC, adversely associated with insulin levels and HOMA IR in cases but not in the controls.
Conclusions:
Our findings show that both abdominal obesity and hyperandrogenism contribute to the dyslipidaemia and other metabolic traits of PCOS which all may negatively contribute to the long term health of women with PCOS.International Journal of Obesity accepted article preview online, 26 May 2017. doi:10.1038/ijo.2017.126.
Background
The findings of prospective cohort studies are inconsistent regarding the association between dietary magnesium intake and serum magnesium concentration and the risk of hypertension. We aimed to review the evidence from prospective cohort studies and perform a dose-response meta-analysis to investigate the relationship between dietary magnesium intake and serum magnesium concentrations and the risk of hypertension.
Methods
We searched systematically PubMed, EMBASE and the Cochrane Library databases from October 1951 through June 2016. Prospective cohort studies reporting effect estimates with 95% confidence intervals (CIs) for hypertension in more than two categories of dietary magnesium intake and/or serum magnesium concentrations were included. Random-effects models were used to combine the estimated effects.
Results
Nine articles (six on dietary magnesium intake, two on serum magnesium concentration and one on both) of ten cohort studies, including 20,119 cases of hypertension and 180,566 participates, were eligible for inclusion in the meta-analysis. We found an inverse association between dietary magnesium intake and the risk of hypertension [relative risk (RR) = 0.92; 95% CI: 0.86, 0.98] comparing the highest intake group with the lowest. A 100 mg/day increment in magnesium intake was associated with a 5% reduction in the risk of hypertension (RR = 0.95; 95% CI: 0.90, 1.00). The association of serum magnesium concentration with the risk of hypertension was marginally significant (RR = 0.91; 95% CI: 0.80, 1.02).
Conclusions
Current evidence supports the inverse dose-response relationship between dietary magnesium intake and the risk of hypertension. However, the evidence about the relationship between serum magnesium concentration and hypertension is limited.

Calcium, phosphorus, magnesium and vitamin D have important biological roles in the body, especially in bone metabolism. We aimed to study the reported intake, the disparity between the reported consumption and the level needed for adequacy and food sources of these four nutrients in the Spanish population. We assessed the reported intake for both, general population and plausible reporters. Results were extracted from the ANIBES survey, n = 2009. Three-day dietary reported intake data were obtained and misreporting was assessed according to the European Food Safety Authority (EFSA). Mean ± SEM (range) total reported consumption of calcium, phosphorus, magnesium, and vitamin D for the whole population were 698 ± 7 mg/day (71–2551 mg/day), 1176 ± 8 mg/day, (331–4429 mg/day), 222 ± 2 mg/day (73–782 mg/day), and 4.4 ± 0.1 µg/day (0.0–74.2 µg/day), respectively. In the whole group, 76% and 66%; 79% and 72%; and 94% and 93% of the population had reported intakes below 80% of the national and European recommended daily intakes for calcium, magnesium and vitamin D, respectively; these percentages were over 40% when the plausible reporters were analysed separately. The main food sources were milk and dairy products for calcium and phosphorus, cereals and grains for magnesium and fish for vitamin D. In conclusion, there is an important percentage of the Spanish ANIBES population not meeting the recommended intakes for calcium, magnesium and vitamin D.
Proton pump inhibitors (PPI)-related hypomagnesemia is a potentially life-threatening adverse event first described in 2006. PPIs are widely used in the general population. Information regarding prevalence and risk factors is scarce. We conducted a cross-sectional study in inpatients to evaluate prevalence and associated factors with hypomagnesemia in chronic PPIs users. This is a cross-sectional study of hospitalized adult patients with chronic use of PPIs from January 01, 2012, to December 31, 2018. Chronic use was defined as taking PPIs at least 6 months before hospital admittance. Data were collected from informatized medical records from a University Hospital (Hospital Italiano de Buenos Aires). Hypomagnesemia was defined as a value equal to or less than 1.7 mg/dl. The first hospitalization measurement was retrieved. Thirty-six percent of patients (95% CI 30–43) with chronic PPI use presented hypomagnesemia at admission. Patients with hypomagnesemia presented a higher prevalence of chronic kidney disease (18.6% vs 8%, p < 0.05), more use of oral magnesium supplementation (20.9% vs 8%, p < 0.05), use of corticosteroids (32.6% vs 19.3%, p = 0.06) and calcineurin inhibitors (17.4% vs 6.7%, p < 0.05). Regarding laboratory findings, they presented lower hematocrit (28.7% vs 32.8%, p < 0.05), phosphatemia (3 mg/dl vs 3.4 mg/dl, p < 0.05), natremia (135 mg/dl vs 136 mg/dl, p < 0.05) and albumin levels (2.8 g/dl vs 3.2 g/dl p < 0.05) when compared to those who presented normomagnesemia. Hypocalcemia was more frequent among patients with hypomagnesemia (57% vs 38.7%, p < 0.05). In the multivariate analysis, hyponatremia, decreasing levels of hematocrit (odds ratio, OR 0.93–CI 95% 0.88–0.98) and malignant bone compromise (OR 2.83–CI 95% 1.04–7.7) were associated with hypomagnesemia. Adult patients with long-term use of PPIs have a high prevalence of hypomagnesemia. Increasing age, female sex, concomitant use of drugs that impair tubular function and chronic kidney disease may enhance this phenomenon. Anemia, hyponatremia and malignant bone compromise were associated factors with PPIs-related hypomagnesemia.
Context:
Experimental studies suggest that magnesium levels in pregnant women may affect the length of gestation, as magnesium affects the activity of smooth muscle in the uterus. Little is known about the association between magnesium levels or supplementation and the rate of preterm birth.
Objective:
The aim of this systematic review was to summarize the data on magnesium soil levels and preterm birth rates from ecological, observational, and interventional studies.
Data sources:
Soil magnesium levels were obtained from US Geological Survey data, and preterm birth rates were acquired from the March of Dimes Foundation. Relevant epidemiological and clinical studies published until April 2019 in peer-reviewed journals were retrieved from PubMed, Google Scholar, and related reference lists.
Study selection:
Original studies published in English, conducted in humans, and in which magnesium (dietary/supplemental intake or biomarkers) was an exposure and preterm birth was an outcome were included.
Data extraction:
Eleven studies were included in the systematic review. Meta-analysis was performed on 6 studies. Overall relative risk (RR) and corresponding 95%CIs for risk of preterm birth in relation to magnesium supplementation were estimated by a random-effects model.
Results:
The ecological study revealed an inverse correlation between magnesium content in soil and rates of preterm birth across the United States (r = -0.68; P < 0.001). Findings from 11 observational studies generally support an inverse association between serum magnesium levels and rates of preterm birth. Of the 6 eligible randomized controlled trials, which included 3068 pregnant women aged 20 to 35 years and 352 preterm infants, the pooled RR was 0.58 (95%CI, 0.35-0.96) for women in the magnesium supplementation group compared with women in the control group.
Conclusions:
Accumulated evidence from ecological, observational, and interventional studies consistently indicates that adequate magnesium intake during pregnancy may help reduce the incidence of preterm birth.
Objectives:
The aims of this study were to examine the relationships between menopausal symptoms, sense of coherence (SOC), coping strategies, and quality of life, and to test the mediating effects of SOC and coping strategies on the relationships between menopausal symptoms and quality of life among Chinese women during menopausal transition.
Methods:
Two hundred one women aged 40 to 60 years and currently undergoing menopausal transition were recruited at community centers between June and August 2017. Menopausal symptoms, SOC, coping strategies, and quality of life were assessed by the Menopause Rating Scale, the Sense of Coherence Scale, the Brief COPE Inventory, and the Medical Outcomes Study Short-Form-36, respectively. Data were analyzed by path analysis.
Results:
Menopausal symptoms were associated with poorer quality of life, and both SOC and maladaptive coping were found to mediate the effects of menopausal symptoms on quality of life. The results suggest that SOC might alleviate the adverse effects of menopausal symptoms on quality of life, whereas maladaptive coping strategies might aggravate the adverse effects of menopausal symptoms on quality of life.
Conclusions:
The results provide new insights into the importance of considering SOC and coping strategies and their interactions with menopausal symptoms and quality of life in the situation of menopausal transition.
Background
Depression is an important public health problem. The aim of the present study is to examine the association of dietary magnesium intake with risk of depression.
Methods
We assessed the association between dietary magnesium intake and risk of depression in a nationally representative sample of 17,730 adults from the 2007–2014 National Health and Nutrition Examination Survey. Magnesium intake was assessed by 24 h dietary recalls. Depression was assessed using the Patient Health Questionnaire-9. Logistic regression and restricted cubic spline models were applied to assess the relationship between dietary magnesium intake and risk of depression.
Results
Dietary magnesium intake was inversely associated with risk of depression, and the multivariate adjusted odds ratio (95% confidence interval) of depression for the highest vs lowest category of dietary magnesium intake was 0.47(0.34–0.66). In subgroup analysis, dietary magnesium intake was inversely associated with risk of depression among women whereas no association was found among man. The inverse association between dietary magnesium intake and risk of depression was statistically significant among all age groups. A linear relationship (Pfor nonlinearity = 0.34) was found between dietary magnesium intake and risk of depression in dose–response analysis.
Limitations
This was a cross-sectional study, thus causality cannot be inferred. In addition, data was based on self-reports.
Conclusions
Dietary magnesium intake was inversely associated with the risk of depression in a linear manner, which still needs to be confirmed by larger prospective studies.
Collective evidence underpinning the Developmental Origins of Health and Disease (DOHaD) hypothesis demonstrates that interventions to improve the nutritional environment during early life offer an important opportunity for primary prevention of DOHaD-related noncommunicable diseases (NCDs). This evidence has led to important programs targeting pregnancy and early childhood. However, addressing the full potential of the DOHaD paradigm also requires consideration of the periconceptional period, and therefore health behaviors prior to pregnancy and parenthood, alongside the complex array of personal and societal factors influencing these behaviors. Therefore, adolescence, the life stage during which cognitive, psychosocial, and lifestyle behaviors that persist into adulthood are formed, should be a key DOHaD intervention point. Schools and tertiary institutions play a major role in the lives of adolescents, supporting the development of capabilities associated with engaged citizenship including scientific and health literacies and key life competencies. Providing young people who are developing these capabilities with opportunities to examine evidence about NCD risk and prevention can empower adolescents to engage in development of and/or participation in evidence-based actions that can contribute toward interrupting the transgenerational conditioning/programming of NCD vulnerability. Realizing the potential of interventions that target the adolescent life stage requires effective cross-sectoral partnerships between education, science, and public health. Education should be a key partner, bringing important expertise alongside that of health and science to facilitate the task of the translation of DOHaD evidence to adolescents within community settings.
Data on the effects of magnesium and vitamin E co-supplementation on glycemic control and markers of cardio-metabolic risk of patients with polycystic ovary syndrome (PCOS) were collected. This investigation was conducted to evaluate the effects of magnesium and vitamin E co-supplementation on glycemic control and markers of cardio-metabolic risk in women with PCOS. This randomized, double-blind, placebo-controlled trial was carried out on 60 women with PCOS, aged 18–40 years old. Participants were randomly divided into two groups to receive 250 mg/day magnesium plus 400 mg/day vitamin E supplements or placebo (n=30 each group) for 12 weeks. Fasting blood samples were taken at baseline and after the 12-week intervention to quantify related variables. After the 12-week intervention, compared with the placebo, magnesium and vitamin E co-supplementation led to a significant reduction in serum insulin levels (–1.1±3.0 vs. +1.6±3.7 μIU/ml, p=0.003) and homeostatic model of assessment for insulin resistance (–0.2±0.7 vs. +0.4±0.9, p=0.002), and a significant increase in the quantitative insulin sensitivity check index (+0.01±0.01 vs. –0.009±0.02, p=0.003). Furthermore, magnesium plus vitamin E supplementation significantly decreased serum triglycerides (–15.0±24.4 vs. +6.7±22.2 mg/dl, p=0.001) and VLDL-cholesterol concentrations (–3.0±4.9 vs. +0.6±2.4 mg/dl, P=0.01) compared with the placebo. A trend toward a greater decrease in total cholesterol levels was observed in magnesium plus vitamin E group compared to placebo group (–7.0±32.6 vs. +8.1±26.6 mg/dl, p=0.05). In conclusion, magnesium and vitamin E co-supplementation for 12 weeks to PCOS women had beneficial effects on parameters of insulin metabolism and few markers of cardio-metabolic risk.
Hypertension accounts for 1 in 5 deaths among American women, posing a greater burden for women than men, and is among their most important risk factors for death and development of cardiovascular and other diseases. Hypertension affects women in all phases of life, with specific characteristics relating to risk factors and management for primary prevention of hypertension in teenage and young adult women; hypertension in pregnancy; hypertension during use of oral contraceptives and assisted reproductive technologies, lactation, menopause, or hormone replacement; hypertension in elderly women; and issues of race and ethnicity. All are detailed in this review, as is information relative to women in clinical trials of hypertension and medication issues. The overarching message is that effective treatment and control of hypertension improves cardiovascular outcomes. But many knowledge gaps persist, including the contribution of hypertensive disorders of pregnancy to cardiovascular disease risk, the role of hormone replacement, blood pressure targets for elderly women, and so on.
Research considering the relationship between dietary Mg and osteoporosis as well as fractures are sparse and conflicting. We therefore aimed to investigate Mg intake and the onset of fractures in a large cohort of American men and women involved in the Osteoarthritis Initiative over a follow-up period of 8 years. Dietary Mg intake (including that derived from supplementation) was evaluated through a FFQ at baseline and categorised using sex-specific quintiles (Q); osteoporotic fractures were evaluated through self-reported history. Overall, 3765 participants (1577 men; 2071 women) with a mean age of 60·6 ( sd 9·1) years were included. During follow-up, 560 individuals (198 men and 368 women) developed a new fracture. After adjusting for fourteen potential confounders at baseline and taking those with lower Mg intake as reference (Q1), men (hazard ratio (HR) 0·47; 95 % CI 0·21, 1·00, P =0·05) and women (HR 0·38; 95 % CI 0·17, 0·82, P =0·01) in the highest quintile reported a significantly lower risk for fracture. Women meeting the recommended Mg intake were at a 27 % decreased risk for future fractures. In conclusion, higher dietary Mg intake has a protective effect on future osteoporotic fractures, especially in women with a high risk for knee osteoarthritis. Those women meeting the recommended Mg intake appear to be at a lower risk for fractures.
A growing amount of evidence suggests that magnesium deficiency may play an important role in several clinical conditions concerning women health such as premenstrual syndrome, dysmenorrhea, and postmenopausal symptoms. A number of studies highlighted a positive correlation between magnesium administration and relief or prevention of these symptoms, thus suggesting that magnesium supplementation may represent a viable treatment for these conditions. Despite this amount of evidence describing the efficacy of magnesium, few and un-systematize data are available about the pharmacological mechanism of this ion for these conditions. Herein, we review and systematize the available evidence about the use of oral magnesium supplementation in several gynecological conditions and discuss the pharmacological mechanisms that characterize these interventions. The picture that emerges indicates that magnesium supplementation is effective in the prevention of dysmenorrhea, premenstrual syndrome, and menstrual migraine and in the prevention of climacteric symptoms.
