Background: Children and young people (CYP) with comorbid physical and/or mental health conditions often struggle to receive a timely diagnosis, access specialist mental health care, and more likely to report unmet healthcare needs. Integrated healthcare is an increasingly explored model to support timely access, quality of care and better outcomes for CYP with comorbid conditions. Yet, studies evaluating the effectiveness of integrated care for paediatric populations are scarce. Aim and methods: This systematic review synthesises and evaluates the evidence for effectiveness and cost-effectiveness of integrated care for CYP in secondary and tertiary healthcare settings. Studies were identified through systematic searches of electronic databases: Medline, Embase, PsychINFO, Child Development and Adolescent Studies, ERIC, ASSIA and British Education Index. Findings: A total of 77 papers describing 67 unique studies met inclusion criteria. The findings suggest that integrated care models, particularly system of care and care coordination, improve access and user experience of care. The results on improving clinical outcomes and acute resource utilisation are mixed, largely due to the heterogeneity of studied interventions and outcome measures used. No definitive conclusion can be drawn on cost-effectiveness since studies focused mainly on costs of service delivery. The majority of studies were rated as weak by the quality appraisal tool used. Conclusions: The evidence of on clinical effectiveness of integrated healthcare models for paediatric populations is limited and of moderate quality. Available evidence is tentatively encouraging, particularly in regard to access and user experience of care. Given the lack of specificity by medical groups, however, the precise model of integration should be undertaken on a best-practice basis taking the specific parameters and contexts of the health and care environment into account. Agreed practical definitions of integrated care and associated key terms, and cost-effectiveness evaluations are a priority for future research.
An overdenture is a denture supported partly by soft tissues and partly by retained teeth or implants. Magnetic tooth-retained overdentures are used to increase support, retention, and stability but also prevent alveolar ridge resorption. Magnetic attachments increase the retention of partial or complete dentures regardless of the path of the insertion and, in addition, can be used for abutment teeth with periodontal disease. This paper discusses two oral rehabilitation cases with total and partial tooth-retained overdenture.
Helicobacter pylori (Hp), a well-known human pathogen, causes one of the most common chronic bacterial infections and plays an important role in the emergence of chronic progressive gastric inflammation and a variety of gastrointestinal diseases. The prevalence of Hp infection varies worldwide and is indirectly proportional to socio-economic status, especially during childhood. The response to the eradication therapy significantly depends on the antibiotic resistance specific to each geographical region; thus, currently, given the increasing prevalence of antimicrobial resistance (especially to clarithromycin, metronidazole, and levofloxacin), successful treatment for Hp eradication has become a real challenge and a critical issue. The most incriminated factors associated with multidrug resistance (MDR) in Hp proved to be the overuse or the improper use of antibiotics, poor medication adherence, and bacterial-related factors including efflux pumps, mutations, and biofilms. Up to 30% of first-line therapy fails due to poor patient compliance, high gastric acidity, or high bacteremia levels. Hence, it is of great importance to consider new eradication regimens such as vonoprazan-containing triple therapies, quintuple therapies, high-dose dual therapies, and standard triple therapies with probiotics, requiring further studies and thorough assessment. Strain susceptibility testing is also necessary for an optimal approach.
The middle ear represents the anatomic space between the external auditory canal and the inner ear (Cochlea). It is comprised of the tympanic membrane, the ossicular chain [malleus (hammer), incus (anvil) and stapes (stirrup)] with the corresponding muscles and ligaments and the cavity of the middle ear. The main function of the middle ear is to convey vibratory energy (sound pressure) from the air to the cochlear fluids of the internal ear via the ossicular chain. Tympanoplasty represents a number of procedures used to re‑establish the continuity of sound transmission from the tympanic membrane to the inner ear. Ever since the beginning of otologic surgery, various materials have been tested for ossicular chain reconstruction (OCR). The present review aimed to present, in a chronological sequence, the evolution of knowledge regarding this field of medicine, and to also discuss the advantages and disadvantages of different materials and designs of ossicular prostheses. The constant search for more efficient, easily tolerated and lighter materials has improved the acoustic rehabilitation process and has markedly reduced the rate of functional failure of these small prostheses. Contents 1. Introduction 2. Data collection 3. History and evolution of ossicular chain reconstruction 4. Conclusions and future perspectives
Castleman’s disease is a benign lymphoproliferative disorder. The coexistence of Hodgkin’s lymphoma and multicentric Castle-man’s disease is a rare phenomenon. We discuss a case of a 48-year-old female patient who had been in the records of the Colentina Hematology Clinic since 2019, with the diagnosis of classic Hodgkin’s Lymphoma, nodular sclerosis type I BNLI, stage IIXB. For this, she underwent 3 courses of ABVD and 2 courses of BEACOPP, without showing complete remission on PET/CT evaluation at the end of treatment. After that, we initiated rescue therapy and performed 4 IGEV courses, followed by autologous stem cell transplantation. For maintenance treatment, we opted for Brentuximab, but it was discontinued after the first administration due to the appearance of adverse reactions. Subsequently, we decided to perform radiotherapy with 20 fractions cumulating a total dose of 36 Gy. Shortly after the radiotherapy, symptoms reappeared which were suspected to be in the context of a relapse of the disease. For confirmatory diagnosis, we performed a new PET-CT which highlighted metabolically active ganglion images. Further, were carried out lymph node biopsy for histopathological and immunohistochemical examinations were carried out. The underlying disease was diagnosed as plasmacytic subtype, HHV8 negative, multicentric Castleman’s disease. For treatment, we relied on administrations of Siltuximab treatment therapy that showed complete remission. Castleman’s disease presents a unique diagnostic challenge, but a confirmatory diagnosis can be based on a biopsy examination, advisable after each relapse.
Immune tolerance at the feto-maternal interface is crucial for the growth of the semi-allograft fetus in the womb. The outcome of pregnancy is dependent on a fine balance between various immunological forces. For a long time, the potential role of the immune system in pregnancy disorders has remained enigmatic. Current evidence has revealed that natural killer (NK) cells are the predominant immune cell population in the uterine decidua. NK cells cooperate with T-cells to provide an optimal microenvironment for the growth of the developing fetus by producing cytokines, chemokines, and angiogenic factors. These factors support trophoblast migration and angiogenesis which regulates the process of placentation. NK cells differentiate between “self” and “non-self” through their surface receptors known as killer-cell immunoglobulin-like receptors (KIRs). They induce immune tolerance through communication via their KIR and fetal human leucocyte antigens (HLA). KIRs are surface receptors of NKs that comprise both activating and inhibiting receptors. Due to the wide diversity manifested by its genes, the KIR repertoire is different in each individual. Significant evidence has implicated KIRs in recurrent spontaneous abortion (RSA); however, maternal KIR gene diversity in RSA is still unclear. Research has shown that immunological aberrancies including activating KIRs, NK abnormalities, and T cell downregulation are risk factors for RSA. In this review, we discuss relevant data from experimental studies on NK cell abnormalities, KIR, and T-cells in the incidence of recurrent spontaneous abortion.
Studies have shown that an organization’s corporate social responsibility (CSR) activities affect customer behaviors such as loyalty and satisfaction. In spite of this, the role of social media in informing customers about a brand’s CSR activities and in fostering customer advocacy behavior (CADB) has been underexplored. To fill this knowledge gap, this study investigates the relationship between the CSR-related communication of a banking organization and CADB. This study also examines how emotions such as customer–company identification (CCI) and gratitude as a mediator and a moderator. Using a self-administered questionnaire (n = 302), we collected data from banking customers. Hypotheses were evaluated by using structural equation modeling, which revealed that CSR positively predicts CADB, whereas there are mediating and moderating functions of CCI and GA. Theoretically, this study highlights the role of human emotions in behavior formation from the standpoint of social media. Practically, this study provides important insights for the banking sector’s administrators to realize the important role of CSR communication, using different social networking websites, for converting customers into brand advocates.
Orthodontic treatment can be effective only with the proper adhesion strength of the bonded elements on the teeth. The aim of the study was to analyze the influence of different remineralization products on the brackets (Evolve Low Profile Brackets 0.022 Roth prescription (DB Orthodontics Ltd., Silsden, England) shear bond strength (SBS)). In all, 40 teeth were investigated for this study; n = 30 demineralized (immersed in 0.1% citric acid for 30 min, twice a day, for 20 consecutive days) and n = 10 immersed only in artificial saliva. After the demineralization process, remineralization agents were applied to each group (n = 10): Group I: Elmex Sensitive professional® toothpaste (CP, Gaba GmbH, Witten, Germany) and GC MI Paste Plus® (GC, Leuven, Belgium), Group II: Elmex Sensitive professional® toothpaste (CP, Gaba GmbH, Germany) and GC Tooth Mousse® (Leuven, Belgium), Group III: Elmex Sensitive professional® toothpaste (CP, Gaba GmbH, Germany). For the teeth in control group C, Elmex Sensitive professional® toothpaste was used. SBS tests were performed by means of an advanced materials-testing machine that generated maximum load and tensile strength values. The data obtained underwent statistical analysis (ANOVA and Tuckey test) with a statistical threshold of p < 0.05. The SBS values were higher for group II (14.20 MPa) and I (10.36 MPa) and lower for group III (4.25 MPa) and C (4.11 MPa), with statistically significant differences between groups I and II when compared with groups III and C (p < 0.05). In conclusion, GC Tooth Mousse® and MI-Paste Plus® have no adverse effect on brackets SBS and are recommended to be used for enamel remineralization during orthodontic treatment.
In recent years, the concern for durable electrical and electronic products as well as the recovery and recycling of electrical and electronic waste has increased, simultaneously with new initiatives aimed not only at protecting the environment, but ensuring consumer's health, while consolidating their fundamental rights. The research aims to identify the factors that influence the sustainable behaviour of the Romanian consumer of electrical and electronic products. In this sense, the ecological attitude, the purchasing behaviour of these goods, and also the recovery/recycling attitude of electrical and electronic waste were taken into account. Data were collected through an online questionnaire from 421 Romanian respondents and processed with the lavaan software package version 0.6-12 of R for structural equation modelling. The novelty of the article lies in how variables such as propensity to recover/recycle, tendency of purchasing durable goods, ecological behaviour, are put in a new context, combining environmental and consumers' protection. The research makes theoretical contributions by proposing and testing specific consumer protection constructs, which do not appear in the literature. From the environmental public policies point of view, the work highlights the factors that can contribute to the development of a responsible behaviour of both the population and public authorities, to stimulate the purchase of sustainable goods, and to ensure an increase in the collection rate of electrical and electronic products in Romania. Keywords: electrical and electronic products (EEP), the sustainable consumer behavior, consumer's rights, electrical and electronic equipment waste (WEEE), recycling/recovering.
Cerebral venous thrombosis (CVT) is a rare type of stroke, with a complex clinical presentation that can make it a diagnostic challenge for the swift initiation of anticoagulation. When a hemorrhagic transformation is added, therapeutic management becomes even more complex. We describe a series of four cases, aged between 23 and 37 years old, with cerebral venous thrombosis. They were admitted to our clinic between 2014 and 2022. All cases presented significant challenges in either diagnostic, therapeutic or etiologic evaluation, at different stages of the disease. Late complications such as epilepsy or depression and other behavioral disorders represent long-term sequelae for the patient. Therefore, through its late complications, CVT is not only an acute disease but a chronic disorder with long-term follow-up requirements. The first case of the series is of a postpartum woman with focal neurological deficit caused by CVT with hemorrhagic transformation that presented multiple thrombotic complications and severe depression. The second case is of a man with extensive cerebral thrombosis who developed bilateral papillary edema under therapeutic anticoagulation treatment. The third case is of a woman with bilateral cavernous sinus thrombosis who later developed depressive disorder and focal seizures. The fourth case is of a pregnant woman in the first trimester presenting with a steep decline in consciousness level secondary to deep cerebral vein thrombosis requiring intensive care and subsequently developing a memory disorder. For a long period of time, due to being underdiagnosed, few things were known about CVT. Nowadays, we have all the tools to diagnose, treat, and follow up cases of CVT.
This study does not propose to elucidate how adiponectin secretion is regulated, but how its adiponectin concentration is an indicator of heart disease. About adiponectin, it is not known whether it is functionally an enzyme, or very likely a cytokine/chemokine/hormone, secreted by fat cells/adipocytes in the abdomen. Abdominal fat secretes 67 hormones, and all of which cause disease. For example, adiponectin generates diabetes and ischaemic heart disease via dyslipidemia. Based on clinical symptoms, electrocardiographic and echocardiographic parameters, a group of 208 patients with diastolic cardiac dysfunction with or without preserved systolic function, developed on a background of painful chronic ischaemic heart disease, stable angina on exertion, was constituted. The serum levels of adiponectin, total cholesterol, LDL cholesterol, HDL cholesterol and triglycerides were measured. Using the identified values, it was appreciated whether adiponectin correlates with the type of any of the two conditions, so that it can be recognised as a diagnostic and risk stratification marker.
The problems that have arisen in recent years in Romania (the financial crisis, the COVID-19 pandemic, the accelerated growth of inflation and unemployment) have led many people to give less and less importance to dental hygiene, which has led to an increase in the number of people with dental medical problems. In addition, poor information about the need for regular visits to the dentist, the low importance given to this field, and insufficient financial resources led people to turn to dental medical services less often. Moreover, the two-month closure of medical practices during the COVID-19 pandemic made individuals more reluctant to make appointments with dentists for fear of coming into contact with a person infected with the new SARS-CoV-2 virus. All this led to the occurrence of dental complications among patients, which made the number of dental implants increase. Patients suffering from diabetes mellitus present a series of particularities due to a series of risks generated by this condition that may appear in their case. The aim of this research is to identify the main factors that can influence the decision of patients with diabetes mellitus to have a dental implant. The data collection was performed with the help of a questionnaire, and the analysis of the database was performed with the help of IBM SPSS software. Following the analysis, it was noted that this decision is largely influenced by the reputation of the medical practice, the perceived risks, the quality of the materials used, the warranty of the dental implant, the quality of the services provided, and the costs.
The functional sequelae grouped under the name “long COVID” most often bring the patient in front of a team of specialists in pulmonary rehabilitation. The aim of this study was to evaluate clinical features and paraclinical findings in patients with SARS CoV-2 (Severe Acute Respiratory Syndrome-Corona Virus-2) pneumonia and to also evaluate the impact of rehabilitation in this category of patients. This study included 106 patients diagnosed with SARS CoV-2. The division of the patients into two groups was performed based on the presence of SAR-CoV-2 pneumonia. Clinical symptoms, biochemical parameters, and pulmonary functional and radiological examinations were recorded and analyzed. The Lawton Instrumental Activities of Daily Living (IADL) scale was applied to all patients. Patients in group I were included in the pulmonary rehabilitation program. Among demographic characteristics, age over 50 years (50.9%; p = 0.027) and the female sex (66%; p = 0.042) were risk factors for pneumonia in patients with SARS CoV-2. Over 90% of the 26 patients included in the rehabilitation program were less able to feed, bathe, dress, and walk. After 2 weeks, approximately 50% of patients were able to eat, wash, and dress. It is important to provide longer rehabilitation programs in cases of moderate, severe, and very severe COVID-19 patients, in order to significantly improve patients’ participation in daily activities and their quality of life.
Background Laparoscopic Sleeve Gastrectomy (LSG) is the most attractive bariatric procedure, but the postoperative intrathoracic gastric migration (ITM) and “de novo” GERD are major concerns. The main objective of our study was to evaluate the efficiency of the concomitant HHR with or without partial reconstruction of phreno-esophageal ligament (R-PEL) to prevent ITM after LSG. The secondary objectives focused on procedure’s metabolic and GERD-related outcomes. Patients and method Consecutive patients who underwent primary LSG and concomitant HHR were included in a single-center prospective study. According to the HHR surgical technique, two groups were analyzed and compared: Group A included patients receiving crura approximation only and Group B patients with R-PEL. The patients’ evolution of co-morbidities, GERD symptoms, radiologic, and endoscopic details were prospectively analyzed. Results Two hundred seventy-three patients undergoing concurrent HHR and LSG were included in the study (Group A and B, 146 and 127 patients) The mean age and BMI were 42.6 ± 11.3 and 43.4 ± 6.8 kg/m². The 12-month postoperative ITM was radiologically found in more than half of the patients in Group A, while in group B, the GEJ’s position appeared normal in 91.3% of the patients, meaning that R-PEL reduced 7 times the rate of ITM. The percentage of no-improvement and “de novo” severe esophagitis (Los Angeles C) was 4 times higher in group A 3.4% vs. 0.8% with statistical significance, and correlated to ITM. The GERD symptoms were less frequent in Group B vs Group A, 21.3% vs 37%, with statistical significance. No Barrett’s esophagus and no complication were recorded in any of the patients. Conclusion Concurrent LSG and HHR by crura approximation only has a very high rate of ITM in the first postoperative year (over 50%). R-PEL is an innovative technique which proved to be very efficient in preventing the ITM after HHR.
Total knee arthroplasty (TKA) remains a lifesaving procedure for advanced gonarthrosis. However, patella resurfacing (PR) in TKA remains a controversial procedure, leading to extensive discussions amongst orthopedic surgeons, regarding its indications and results. Based on these premises, we present a clinical case of a 70-year-old Caucasian woman admitted for pain, swelling and limitation of left knee joint mobility. Her medical history records an Ahlback stage IV gonarthrosis with simultaneous bilateral TKA surgery performed in different hospital, when two NexGen cemented total prostheses were implanted with patellar resurfacing being performed only on the right side. Our clinical (American Knee Society Score, Lonner and Feller scales) and radiological evaluations (CT scan and Xray) revealed left patellar arthrosis and a slight lateral subluxation of the patella. The chosen treatment plan was revision surgery for PR and patellar prosthesis with a cemented patellar component, cross-linked polyethylene, no 32 NexGen model with 8.5 mm thickness. The immediate and distant postoperative evolution was favorable. Extensive literature review shows that, at present, PR remains at surgeon`s discretion mainly based on his previous results. Therefore, we believe there is an imperative need to develop high quality studies based on accurate scientific evidence to universally establish valid guidelines for PR in TKA.
Background: Hemorrhoidal disease (HD) is considered a low-severity pathology by both general population and physicians, but the lengthy conservative therapy and postoperative complications suggest otherwise. Aim: To assess the effectiveness of different treatment options, both conservative and surgical, in contrast with some preexisting comorbidities. Methods: We conducted a retrospective, 10-yearlong study between January 2011 and December 2021 in two surgical centers, a private and a state-owned hospital. We compared the efficacy and safety of several treatment options, such as open hemorrhoidectomy, stapled hemorrhoidopexy, rubber band ligation and infrared coagulation in terms of complication rates and types and their correlation with different preexisting comorbidities such as inflammatory bowel disease (IBD), use of anticoagulant medication (AM) and liver cirrhosis. We also conducted a 20-years long PubMed research (1.263 articles) for relevant comparisons. Results: Our study recorded 10940 patients with HD, 10241 with conservative and 699 with surgical treatment. Out of these, the male-to-female ratio of 1.3, and a peak in age distribution between 59 and 68 years old (32% of patients). For the entire study, we recorded a 90% incidence of immediate pain, immediate bleeding in 1.5% (11 cases), delayed bleeding in 1.0% (7 cases), and 0.6% surgical site infections. Urinary retention was also present, with 0.2% of patients, anal stricture in 1% and fecal incontinence for 0.5% of patients (4 cases). We recorded no severe complications such as Fournier`s gangrene or rectovaginal perforations. IBD accounted for 6% of the patients, with ulcerative colitis in 12% and Chron`s disease in 10.5%. 6.6% of the patients had AM, determining 4% immediate and 2% delayed bleeding, in surgically treated patients. Conclusion: Our study determined that most common complications (pain, urinary retention, bleeding, and stricture) are correlated with each surgical technique and pre-existing comorbidities.
The incidence of isolated iliac artery aneurysms is approximately 2% and common iliac artery pseudoaneurysms are even rarer. A pseudoaneurysm is a localized hemorrhage as opposed to an actual aneurysm, which affects the entire vascular wall. They are typically asymptomatic and only detectable accidentally while looking for other causes. If large and symptomatic, they typically exhibit pressure symptoms as a result of the compression of the structures around them. Common symptoms include generalized stomach pain, urological problems, gastrointestinal bleeding, and neurological symptoms such as leg paralysis or sciatica-like back pain. Rarely, they may exhibit hemodynamic instability together with an aneurysm rupture, which has a high fatality rate. Due to the unique presentation, the diagnosis is typically rarely made and there is little experience with treating it. We report two cases of common iliac artery pseudoaneurysm found in two patients who had no notable medical history and who we chose to repair through the endovascular technique in the first case, an approach that has gained more ground for vascular repair worldwide, making it the current go-to method, and for the second case we chose a more traditional approach, through open surgery.
Because of the fast rise of Internet commerce, a firm now has access to a plethora of new communication channels in addition to conventional ones and the problem is determining the best balance of physical and online channels. Due to the fact that their role in the value chain is to be close to green consumers, these businesses can effectively implement multichannel communication strategies. The purpose of this study is to determine how the use of integrated digital communication could change how green customers act in multichannel retail. The data from 396 respondents with multichannel retailing experience were collected to conduct an empirical investigation on social media platforms, i.e., Twitter, Facebook, and Instagram, which was then analyzed using structural equation modeling (SEM). The study’s findings emphasized the significance of planning, implementing, and regulating multichannel communication on the one hand and the impacts of recognizing the unique demands of integrated information and communication of green customers in multichannel retail on the other. The relevance of this study is that it provides insights into green consumer decision-making research and integrated digital communication to manage consumer relationships.
Dicrotic wave fiducial point can represent a useful key metric for vasomotor activity evaluation and its morphology during a complete cardiac cycle gives insight about hemodynamic activity, especially for changes in blood pressure values. As an important fiducial point, despite of human evaluation, its behavior is rarely interpreted by an automated algorithm. The last approach is suitable for individual monitoring, but a drawback from scalability point of view. This paper proposes an algorithm for dicrotic wave detection in various blood pressure signal morphologies, extracted from photoplethysmography waveforms. Four major classes with an easy nomenclature to be understand are defined, based on different signals morphologies. A total of high quality 400 periods where visual inspected and selected to build a reference database for algorithm performance testing. An overall performance of 95.25% is obtained, but this detection rate is pulled down especially by depicted classes where dicrotic wave is almost absent and affected by the artifacts. The tested dataset has discarded unrealistic waveform suffering from artifact effect. The main source of error is due to multiple weak inflection points during one cardiac cycle, comparable in morphology with the investigated fiducial points.
