Background The prevalence of inflammatory bowel disease (IBD) is increasing worldwide, affecting millions of individuals. The highest incidence and prevalence are found in Northern Europe and Northern America. There is a lack of new epidemiological studies in the Eastern European region. The objective of this study was to assess changes in the prevalence of IBD in Lithuania during two last decades. Methods Data on the prevalence of Crohn's disease (CD) and ulcerative colitis (UC) (ICD-10 code K50, K51) in Lithuania during 2001-2020 were obtained from the Institute of Hygiene, where the data were systematized from the Mandatory Health Insurance Information System. Changes in the prevalence trends in men and women, children and adults during 2001-2020 were assessed using Joinpoint regression analysis. Results In 2020, the overall prevalence of CD was 33/100,000 and the prevalence of UC was 117/100,000. Gender differences in the prevalence of IBD were not significant. The prevalence of CD among adults in Lithuania has increased 3-fold over 20 years, while the prevalence of UC has increased 4-fold. During 2001-2020, the average annual increase in UC prevalence (8.0%/year, p<0.001) was higher than in CD (6.3%/year, p<0.001). Also, it shows increased UC/CD ratio: in 2001, the ratio was 2.5:1, while in 2020, was observed a higher UC/CD ratio 3.5:1. When comparing changes in the prevalence of IBD, some differences were observed between adults and children. During 2001-2020, the average annual growth rate of CD in children increased not significantly (2.1%/year, p>0.05), while for adults, a significant increase was observed (6.8%/year, p<0,001). Similar trends were noticed in the assessment of the prevalence changes of UC: during 2001-2020, the prevalence of UC in children increased slightly (3.1%/year, p>0.05), while significant growth was observed for adults (7.8%/year, p<0.001). When comparing the children prevalence ratio of CD and UC, it remained almost the same over 20 years, and it was found that CD is more commonly diagnosed in children than UC (CD/UC ratio in 2001 was 1.8:1, while in 2020, it was 1.7:1). In adults, CD/UC ratio was opposite of children, and has changed during 2001-2020: CD/UC ratio in 2001 was 1:2.9, while in 2020, it was 1:3.7. Conclusion The results show that the prevalence of IBD in adults is steadily increasing, while the number of cases in children has not changed significantly over 20 years. Also, it was observed, that Crohn's disease is diagnosed at younger age than ulcerative colitis, which is more commonly diagnosed in older age.
Background Common infections are becoming almost untreatable, all because of the emergence and spread of drug-resistant pathogens. The highest risk is carried by rapidly spreading multi and pan-resistant bacteria that cause infections untreatable with existing antibiotics. Nowadays the biggest concern is Klebsiella bacteria which reportedly has resistance percentages of 25% or higher for third-generation antimicrobial medicine (WHO, 2022). Orally delivered recombinant bacteriocins, like klebicins, could be employed as oral antimicrobials to eradicate multidrug-resistant Klebsiella from the intestinal tract before hospitalization. Methods This study aimed to investigate the antimicrobial efficacy of orally delivered Eudragit - coated klebicin (KvarM) in a murine gastrointestinal tract model of K. pneumoniae infection. Biomodels were used (5 animals/group) to test the antimicrobial efficacy of orally delivered klebicin KvarM: vehicle-only control group (K. pneumoniae, Eudragit coating) and experimental group with K. pneumoniae and KvarM coated to be released in small and large intestines. Faecal samples were used for the analysis of Klebsiella haemolysin gene (khe), which is highly specific for Klebsiella species, using RT-PCR. Results The gastrointestinal model of K. pneumoniae infection in mice was achieved per os without any antibiotic pretreatment following the introduction of coated klebicin KvarM therapy once per day for four days. In the first experimental group, the amounts of K. pneumoniae changed from 6,15 x 106 CFU/50 mg after K. pneumoniae administration to 4,68 x 106 CFU/50 mg after the last dose of therapy (23,9 percent efficacy) in the experimental group. Nonetheless, there was a significant difference between the vehicle-control group and the first group after klebicin administration (p=0,023). Conclusion Our study shows that the K. pneumoniae infection in the intestinal tract of mice was reduced by 23,9 percent and can be significantly lowered in bacterial counts using orally delivered klebicin.
Background The Epi-IBD cohort is a prospective European population-based cohort of 1,390 patients diagnosed in 2010 and 2011 with inflammatory bowel disease (IBD) according to Copenhagen criteria in centres from Eastern and Western European countries. The study aims at describing differences in incidence, treatment strategies, disease course and prognosis of Crohn’s disease (CD) across Eastern and Western Europe. Methods CD patients were followed prospectively from the time of diagnosis until December 31st, 2020, death, emigration or loss of follow-up. Clinical data on surgery, hospitalizations, and medical treatment, were captured throughout the follow-up period and entered into a validated web-database, Associations between surgery and covariates were analysed by multivariate Cox regression analyses. Results In total, 482 CD patients aged ≥15 years from 21 centres in 5 Eastern and 11 Western European countries were included. At 10-years follow-up, 101 (21%) patients underwent first intestinal resection and 11 out of these 101 patients (11%) underwent additional resections. Furthermore, 176 (37%) patients had at least one CD related hospitalization. Cancer was diagnosed in 21 (4%) patients, including 4 gastrointestinal cancers. The use of IBD medication was comparable between Eastern and Western European centres apart from 5-aminosalicylic acid agents (Table 1). During follow-up, 60 out of 360 patients (17%) progressed from non-stricturing-non-penetrating disease (B1) at diagnosis to stricturing or penetrating disease (B2 or B3) while 13 out of 83 patients (16%) with stricturing disease (B2) progressed to penetrating disease (B3). The median time to progression was 28 (IQR: 9-64) months from diagnosis. No patients from Eastern Europe were exposed to biological therapy prior to change in behaviour, compared to 23 out of 66 patients (35%) from Western Europe. Multivariate Cox regression analysis showed no difference in risk of surgery according to European region (Eastern vs. Western Europe, HR: 0.54, 95%CI: 0.24-1.21). Early intervention with biological therapy (within 6 months) did not influence the risk of surgery (HR:0.75, 95%CI: 0.31-1.83), however early introduction of immunomodulators reduced the risk significantly (HR:0.54, 95%CI: 0.30-0.98). Progression in behaviour from B1 was associated with higher risk of surgery (HR:7.62, 95%CI: 3.91-14.87). Conclusion After 10 years of follow-up, 21% underwent intestinal resection and 10% required additional resections. Despite the widespread use of immunomodulators and biological therapy, 16% of the patients had disease behavioural progression, which was associated with higher risk of surgery. Early introduction of immunomodulators was found to be beneficial.
Background The advent of new therapeutic agents and the improvement of supporting care might change the management of acute severe ulcerative colitis (ASUC) to avoid colectomy and change the natural history of the disease. The effectiveness and safety of sequential treatment should be evaluated in this scenario. Main aim To evaluate colectomy-free survival in patients with ASUC refractory to intravenous steroids who had failed infliximab (IFX) or ciclosporin (CyA) and received a second salvage therapy. Secondary aims: To evaluate the short-term and long-term effectiveness and to assess the safety of this strategy. Methods Multicentre study of patients admitted with ASUC refractory to corticosteroids who failed CyA or IFX and had received a second salvage therapy during the same hospital stay. Clinical activity was classified based on partial Mayo score and Lichtiger activity index. Patients who stopped second-line therapy due to disease activity or adverse events were considered as failures. Short-term colectomy-free survival was assessed by logistic regression analysis while long-term colectomy-free survival was evaluated by Kaplan-Meier curves and Cox regression models. Results Results: A total of 78 patients from 24 centres were included. As first-line therapy, IFX was administered to 32 patients, and CyA to 46. Baseline characteristics are detailed in table 1. The prescribed salvage therapy was IFX in 45 patients, CyA in 17, tofacitinib in 13, and ustekinumab in 3 (Figure 1). Colectomy was required in 29 patients (37%) during the follow-up (median 14 days, IQR 3-23). Colectomy-free survival curves are shown in figure 2-A and 2-B. Second-line salvage therapy with CyA was associated with a higher rate of colectomy (Figure 2-C). A total of 39 patients (55%) at week 12 and 20 patients (33%) at month 12 had clinical response; 31 patients (44%) at week 12 and 18 (30%) at month 12 were in clinical remission. At the last visit of the study, 26 patients (33%) were still under the second-line therapy. Adverse events (AE) were recorded in 26 patients (33%), being serious in 15. Resolution with no sequelae was observed in 20 patients (77%). No differences in AE between the second-line therapies prescribed were observed. There were two deaths: one due to cerebral thrombophlebitis and another due to bacteriemia after colectomy, both when CyA was the salvage therapy prescribed (Table 2). Conclusion A second-line salvage therapy avoids colectomy in a considerable percentage of patients admitted by ASUC and therefore it could be considered after IFX or CyA failure. The individual therapeutic approach must be discussed with patients due to the risk of serious adverse events.
Background It is well known that skin lesions may be frequent extraintestinal manifestations of inflammatory bowel diseases (IBD). During literature analysis we found out that there is an obvious lack of epidemiological data regarding this issue. Therefore, the aim of our study was to establish the prevalence of skin lesions among consecutive IBD patients in outpatient department. Methods Prospective study included out-patients with IBD who were managed in the hospital of Lithuanian University of Health Sciences from January to October of 2022. Patients completed the questionnaires including the demographic and the IBD data and history or present state of cutaneous lesions. We considered skin lesions related to IBD or its treatment if they were diagnosed following the diagnosis of IBD. Skin lesions which were reported before the diagnosis of IBD were considered as not related to IBD. Results 152 patients were included, mean age (MA) – 42.0±13.9 years. There were 88 (57.9%) males and 64 (42.1%) females. Ulcerative colitis (UC) was diagnosed in 110 (72.4%) patients, Crohn’s disease (CD) – in 42 (27.6%) patients. MA of UC patients was 42.3±13.6, CD – 41.1±14.9, p>0.05. In total, skin lesions were indicated by 65 (42.8%) subjects. According to our criteria, in 46 (30.3%; 95% CI: 23-38%) cases, skin lesions were considered as obviously related to IBD or its treatment. We further analyzed latter cases. Among UC patients, 32 (29.1%; 95% CI: 20-38%) had skin lesions related to IBD, among CD patients – 14 (33.3%; 95% CI: 18-48%), p>0.05. Erythema nodosum was diagnosed in 6 (3.9%) patients, pyoderma gangrenosum – 5 (3.3%), acne – 1 (0.7%), psoriasis – 9 (5.9%), vitiligo – 2 (1.3%), epidermolysis bullosa acquisita – 1 (0.7%), hemorrhagic vasculitis – 1 (0.7%), eczema – 9 (5.9%), allergic rash – 4 (2.6%). The comparison of different skin lesions among UC and CD patients is presented in table 1. Among the patients with UC proctitis, skin lesions were reported in 2 of 15 (13.3%) patients; among left-sided colitis – in 8 of 27 (29.6%); among pancolitis – in 22 of 67 (32.8%), p=0.03 between the groups of proctitis and pancolitis. Comparing the different forms of CD, skin lesions were reported in 3 of 15 (20.0%) patients with ileitis, 4 of 10 (40.0%) patients with colitis and 7 of 17 (41.2%) patients with ileocolitis; p>0.05 between different groups. Conclusion In our series the prevalence of skin lesions obviously related to IBD or its treatment is 30.3%. There were no differences in the prevalence of skin lesions between the UC and CD patients. The most common skin lesions in UC were psoriasis and skin eczema, in CD – erythema nodosum and skin eczema. Cutaneous lesions were significantly more prevalent in extensive UC compared to distal disease.
Background In steroid refractory acute severe ulcerative colitis (ASUC), cyclosporine or infliximab are potential rescue treatments to avoid colectomy. Our objective is to assess the short-term and long-term efficacy and safety of cyclosporine versus infliximab as rescue agents. Methods We performed a retrospective analysis of 121 patients admitted with ASUC to a single gastroenterology centre during 2010-2020. ASUC was defined by the Truelove & Witts criteria. Primary outcome was short-term colectomy-free rate, secondary outcomes were severe adverse events, re-hospitalization or need of treatment with steroids within 2 years due to flare ups and colectomy rate at 2-year follow-up. Results 119 patients initially received intravenous corticosteroids, while 2 patients underwent emergency colectomy on the first day. Sixty-four (53%) were females, median age of all patients was 33 (IQR 27-49) years. 66 (55%) patients responded to intravenous corticosteroids (IVS), while 53 (45%) failed to respond to steroid therapy: 45 (37%) patients received second-line rescue therapy (29 with cyclosporine, 16 with infliximab). Evaluating the short-term efficacy of treatment there was no significant difference between cyclosporine and infliximab: during admission colectomy was performed in 10.3% vs. 12.5% of patients, respectively (p=0.826). In terms of long-term outcomes, the colectomy rate was higher in the infliximab group at 2-year follow-up, although the difference did not reach statistical significance (10.3% vs. 31.2%, p=0.079). The need for oral steroids during follow-up was comparable in both groups (38,5% vs. 50%, p=0.481). Comparing patients who did not undergo colectomy, patients in the infliximab group were more often re-hospitalized due to the need for IVS at 2-year follow-up (7.7% vs. 50%, p=0.002). No severe side effects due to infliximab and cyclosporine were observed. Conclusion In the treatment of steroid refractory ASUC infliximab and cyclosporine were equally effective in short-term period and there was no difference in safety, however cyclosporine treated patients trended to have better long-term outcomes, with significantly rarer re-hospitalization. Additional analysis is needed for other factors that may have contributed to differences in long-term outcomes between the cyclosporine and infliximab groups.
Background Ulcerative Colitis (UC) is a chronic, relapsing inflammatory disease of the lower gastrointestinal tract. The frequency of UC is increasing worldwide, however, existing methods for both diagnostics and treatment of this disease are not efficient enough. It is known that besides comprised immune response, environmental and genetic factors, gut microbiota play a major role in the onset and course of UC. Therefore, efforts are currently being made to find and develop new gut microbiome-based tools to improve the management of UC. The aim of this study was to identify changes in the gut microbiome during active and quiescent UC. Methods Study included 72 subjects, who were divided into three age- and sex-matched groups: control (n=25), active UC (n=27) and quiescent UC (n=20). Total DNA was extracted from faeces, which was further subjected to the next generation sequencing of 16S rRNA-coding gene V1-V2 hypervariable region on MiSeq (Illumina) platform. Further, bioinformatics and statistical analysis were performed. Results Bacterial α-diversity, as assessed by Richness, Shannon and Simpson diversity indexes, revealed that control patients had highest α-diversity compared to patients with active UC or quiescent UC (p<0.05), but there were no differences between UC disease states (p>0.05). Significant microbial community clusters (β-diversity), as assessed by the Bray-Curtis dissimilarity index, were identified between control subjects and patients with active or quiescent UC (p=0.02, p<0.01, respectively). However, no significant clusters were found between different disease states (p=0.22). In-between samples dissimilarity assessed by Bray-Curtis dissimilarity index showed that samples from control subjects had higher in-between sample similarity (mean 0.542 ± 0.117) than patients with active (mean 0.638 ± 0.161) and quiescent (0.6 ± 0.145) UC. In addition, 16, 13 and 27 core taxa were identified in active, quiescent UC and control group, respectively. Differential abundance of Cuneatibacter, Faecalibacterium and Prevotellamassilia genera was detected when comparing control vs UC (both active and quiescent), Paraprevotella and Cuneatibacter genera – control vs active UC, Faecalibacterium, Prevotellamassilia, Mediterraneibacter and Cuneatibacter genera – control vs quiescent UC. Conclusion In conclusion, this study revealed both qualitative and quantitative gut microbiota changes in active and quiescent UC. Study was funded by the Research Council of Lithuania (Grant No. S-MIP-20-56).
Background The Epi-IBD cohort is a prospective European population-based cohort of 1,390 patients diagnosed in 2010 and 2011 with inflammatory bowel disease (IBD) according to Copenhagen criteria in centres from Eastern and Western European countries. The study aims at describing differences in incidence, treatment strategies, disease course and prognosis of ulcerative colitis (UC) Eastern and Western Europe. Methods UC patients were followed prospectively from the time of diagnosis until December 31st, 2020, death, emigration or loss of follow-up. Clinical data on surgery, hospitalizations and medical treatment were captured throughout the follow-up period and entered in a validated web-database, Associations between colectomy and covariates were analysed by multivariate Cox regression analyses. Results A total of 816 UC patients aged ≥15 years from 21 centres in 5 Eastern and 11 Western European countries were included. Overall, 51 (6%) patients underwent colectomy. A total of 190 (23%) patients were hospitalized at least once for their UC. Cancer was diagnosed in 28 (3%) patients, including 4 colorectal cancers. The use of medical therapy was comparable across Eastern and Western European centres (Table 1). During follow-up, 121 out of 776 (16%) patients with limited UC (proctitis or left-sided colitis) progressed to extensive colitis. The median time to progression was 21 (IQR: 8-48) months from diagnosis. No patients from Eastern Europe were exposed to biological therapy prior to change in disease extent, compared to 6 out of 98 patients (6%) from Western Europe. Multivariate Cox regression analysis showed no difference in risk of colectomy according to European region (Eastern vs. Western Europe, HR: 1.05, 95%CI: 0.48-2.29). Early intervention with biologicals (within 6 months) was associated with higher risk of colectomy (HR: 3.06, 95% CI: 1.23-7.58), and so was early introduction of immunomodulators (HR: 2.35, 95%CI: 1.16-4.76). Progression in disease extent to extensive colitis was significantly associated with higher risk of surgery (HR: 5.30, 95% CI: 2.36-11.90) and similarly extensive colitis at diagnosis compared to proctitis (HR: 3.48, 95% CI: 1.12-10.82). Conclusion After 10 years of follow up in this European multicentre study, only 6% percent had a colectomy performed. Despite the widespread use of immunomodulators and biologicals, 16% of patients with limited disease extent progressed to extensive colitis which was associated with higher risk of surgery. The need for early introduction of biological therapy and immunomodulators might predict risk of surgery.
Physical exercise is considered a potent countermeasure against various age-associated physiological deterioration processes. We therefore assessed the effect of 12 weeks of resistance training on brain metabolism in older adults (age range: 60–80 years). Participants either underwent two times weekly resistance training program which consisted of four lower body exercises performed for 3 sets of 6–10 repetitions at 70–85% of 1 repetition maximum ( n = 20) or served as the passive control group ( n = 21). The study used proton magnetic resonance spectroscopy to quantify the ratio of total N-acetyl aspartate, total choline, glutamate-glutamine complex, and myo-inositol relative to total creatine (tNAA/tCr, tCho/tCr, Glx/tCr, and mIns/tCr respectively) in the hippocampus (HPC), sensorimotor (SM1), and prefrontal (dlPFC) cortices. The peak torque (PT at 60°/s) of knee extension and flexion was assessed using an isokinetic dynamometer. We used repeated measures time × group ANOVA to assess time and group differences and correlation coefficient analyses to examine the pre-to-post change (∆) associations between PT and neurometabolite variables. The control group showed significant declines in tNAA/tCr and Glx/tCr of SM1, and tNAA/tCr of dlPFC after 12 weeks, which were not seen in the experimental group. A significant positive correlation was found between ∆PT knee extension and ∆SM1 Glx/tCr, ∆dlPFC Glx/tCr and between ∆PT knee flexion and ∆dlPFC mIns/tCr in the experimental group. Overall, findings suggest that resistance training seems to elicit alterations in various neurometabolites that correspond to exercise-induced “preservation” of brain health, while simultaneously having its beneficial effect on augmenting muscle functional characteristics in older adults.
A randomized inter-group trial comparing more intensive treatment strategies to a common standard arm 3 + 7 (CSA) was conducted in patients with non-M3 AML. Untreated patients ≥ 60 years were allocated to the CSA ( n = 132) or to the study group arms ( n = 1154) of the AMLCG (TAD/HAM versus HAM/HAM ± G-CSF followed by TAD and maintenance) and the OSHO (intermediate-dose ara-C/mitoxantrone followed by ara-C/mitoxantrone). Median age of the 1147 eligible patients was 69 (range 60–87) years. CR/CRi status at 90 days was not significantly different between the CSA (54% (95%CI: 45–64)) and the study group arms (53% (95%CI: 47–60) and 59% (95%CI: 58–63)). The five-year event-free survival (EFS) probability (primary endpoint) was 6.2% (95%CI: 2.7–14.0) in the CSA, 7.6% (95%CI: 4.5–12.8) in study group A and 11.1% (95%CI: 9.0–13.7) in B. The 5-year OS was 17.2% (95%CI: 11.0–26.9), 17.0% (95%CI: 2.0–23.9), and 19.5% (95%CI: 16.7–22.8) in CSA, study group A and B, respectively. Neither study group differed significantly from the CSA regarding EFS, OS, or relapse-free survival. In multivariate analyses, allocation to the treatment strategy was not significantly associated with the time-to-event endpoints. The evaluation of more intensive treatment strategies did not show clinically relevant outcome differences when compared to CSA.
Background: Occupational skin diseases have led the occupational disease statistics in Europe for many years. Especially occupational allergic contact dermatitis is associated with a poor prognosis and low healing rates leading to an enormous burden for the affected individual and for society. Objectives: To present the sensitization frequencies to the most relevant allergens of the European baseline series in patients with occupational contact dermatitis (OCD) and to compare sensitization profiles of different occupations. Methods: The data of 16022 patients considered having OCD after patch testing within the ESSCA network between January 2011 and December 2020 were evaluated. Patients (n=46652) in whom an occupational causation was refuted served as comparison group. Results: The highest percentages of OCD were found among patients working in agriculture, fishery and related workers, metal industry, chemical industry, followed by building and construction industry, health care, food and service industry. Sensitizations to rubber chemicals (thiurams, carbamates, benzothiazoles) and epoxy resins were associated with at least a doubled risk of OCD. After a decline from 2014 onwards, the risks to acquire an occupation-related sensitization to methyl(chloro)isothiazolinone (MCI/MI) and especially to methylisothiazolinone (MI) seem to increase again. Sensitization rates to formaldehyde were stable, and to methyldibromo glutaronitrile (MDBGN) slightly decreasing over time. Conclusions: Among allergens in the European Baseline Series, occupational relevance is most frequently attributed to rubber accelerators, epoxy resins and preservatives.

Purpose Results of laryngeal squamous cell carcinoma (LSCC) treatment and the 5 year survival rate of these patients remain poor. To purify therapeutic targets, investigation of new specific and prognostic blood-based markers for LSCC development is essential. Methods In the present study, we evaluated five single nucleotide polymorphisms (SNPs): IL1RAP rs4624606, IL1RL1 rs1041973, IL-6 rs1800795, BLK rs13277113, and TIMP3 rs9621532, and determined their associations with the patients’ 5 year survival rate. Also, we performed a detailed statistical analysis of different LSCC patients’ characteristics impact on their survival rate. Results Three hundred fifty-three LSCC patients and 538 control subjects were included in this study. The multivariable Cox regression analysis revealed a significant association between patients’ survival rate and distribution of IL1RAP rs4624606 variants: patients carrying AT genotype at IL1RAP rs4624606 had a lower risk of death ( p = 0.044). Also, it was revealed that tumor size (T) ( p = 0.000), tumor differentiation grade (G) ( p = 0.015), and IL1RAP rs4624606 genotype ( p = 0.044) were effective variables in multivariable Cox regression analysis prognosing survival of LSCC patients. The specific-LSCC 5 year survival rate was 77%. Conclusions In summary, our findings indicate that the genotypic distribution of IL1RAP rs4624606 influences the 5 year survival rate of LSCC patients. The results of the present study facilitate a more complete understanding of LSCC at the biological level, thus providing the base for the identification of new specific and prognostic blood-based markers for LSCC development.
Introduction For decades in Lithuania, the threat of illicit trade has been used to weaken evidence-based tobacco control policies and to undermine efforts to reduce smoking prevalence and its attributable burden, while also depriving the government of much-needed tax revenue. The aim of this study is to estimate the size of the illicit cigarette market in Lithuania using data from a nationally representative discarded pack collection. Methods The study employed a two-stage cluster design by first randomly selecting 65 well-defined population settlements (30 cities and 35 townships), representing both urban and rural areas, in all 10 counties in Lithuania. Next, we randomly selected 358 polling districts within these settlements. Each polling district had one route along which discarded packs were collected between September 2019 and September 2020. Results In total, 28.9% (95% CIs=27.7 to 30.1) of discarded cigarette packs were classified as illicit. The vast majority (90.1%) of illicit packs originated from Belarus, with most (86.9%) packs produced in the Grodno Tobacco Factory Neman. Tax stamps were present on 93.6% of legal packs, but also on 76% of illegal packs. Conclusions Data from this study suggest that the illicit cigarette trade in Lithuania is more widespread than indicated by other methods and is primarily supplied by the neighbouring Belarus state-owned tobacco factory in Grodno. This signals the need to adopt Belarus-specific border control and security measures. Implications This study presents data from the first national industry-independent study on illicit tobacco trade in Lithuania using discarded cigarette pack collection method. As customs seizure data show, our results also indicate that the illicit cigarette market is primarily supplied by Belarus state-owned Grodno Tobacco Factory Neman, known for filling Europe with cheap cigarettes. An estimate derived from this study is higher than both the industry-independent estimate obtained by the survey method and the estimates offered by the tobacco industry. This adds to the evidence that the difference in estimates obtained by different methods reflects the strengths and weaknesses of each. The study also demonstrates the impact of a rogue neighbour on the illicit market in an adjacent country and offers suggestions on how to address it.
Background Puberty marks the transition from childhood to adulthood and is initiated by activation of a pulsatile GnRH secretion from the hypothalamus. MKRN3 functions as a pre-pubertal break on the GnRH pulse generator and hypothalamic expression and circulating levels of MKRN3 decrease peri-pubertally. In rodents, microRNA miR-30b seems to directly target hypothalamic MKRN3 expression – and in boys, circulating levels of miR-30b-5p increase when puberty is pharmacologically induced. Similarly, miR-200b-3p and miR-155-5p have been suggested to inhibit expression of other proteins potentially involved in the regulation of GnRH secretion. Here we measure circulating levels of these three miRNAs as boys progress through puberty. Materials and Methods Forty-six boys from the longitudinal part of the Copenhagen Puberty Study were included. All boys underwent successive clinical examinations including estimation of testis size by palpation. miR-30b-5p, miR-200b-3p, and miR-155-5p were measured in serum by RT-qPCR using a kit sensitive to the phosphorylation status of the miRNAs. Thirty-nine boys had miRNA levels measured in three consecutive samples (pre-, peri-, and post-pubertally) and seven boys had miR-30b-5p levels measured in ten consecutive samples during the pubertal transition. Results When circulating levels of miR-30b-5p in pre- and peri-pubertal samples were compared with post-pubertal levels, we observed a significant increase of 2.3 and 2.2-fold (p-value<6.0×10 ⁻⁴ ), respectively, and a larger fraction of miR-30b-5p appeared to be phosphorylated post-pubertally indicating an increase in its bioactivity. We also observed a negative correlation between circulating levels of miR-30b-5p and MKRN3. The inter-individual variation in circulating miR-30b levels was substantial and we could not define a clinical threshold for miR-30b-5p suggestive of imminent puberty. Also, miR-155-5p showed significantly increasing levels from the peri- to the post-pubertal stage (p=3.0×10 ⁻³ ), whereas miR-200b-3p did not consistently increase. Conclusion Both circulating levels of miR-30b-5p and its bioactivity increase during the pubertal transition in boys supporting its role in the activation of the HPG axis at the onset of physiologically normal puberty.
Importance The common use of isothiazolinones as preservatives is a global cause of allergic contact dermatitis. Differences in allowable concentrations of methylisothiazolinone (MI) exist in Europe, Canada, and the US. Objective To compare the prevalence of positive patch test reactions to the methylchloroisothiazolinone/methylisothiazolinone (MCI/MI) combination and MI alone in North America and Europe from 2009 to 2018. Design, Setting, and Participants This retrospective analysis of North American Contact Dermatitis Group, European Surveillance System on Contact Allergies (ESSCA), and the Information Network of Departments of Dermatology (IVDK) databases included data from patients presenting for patch testing at referral patch test clinics in North America and Europe. Exposures Patch tests to MCI/MI and MI. Main Outcomes and Measures Prevalence of allergic contact dermatitis to MCI/MI and MI. Results From 2009 to 2018, participating sites in North America and Europe patch tested a total of 226 161 individuals to MCI/MI and 118 779 to MI. In Europe, positivity to MCI/MI peaked during 2013 and 2014 at 7.6% (ESSCA) and 5.4% (IVDK) before decreasing to 4.4% (ESSCA) and 3.2% (IVDK) during 2017 and 2018. Positive reactions to MI were 5.5% (ESSCA) and 3.4% (IVDK) during 2017 and 2018. In North America, the frequency of positivity to MCI/MI increased steadily through the study period, reaching 10.8% for MCI/MI during 2017 and 2018. Positive reactions to MI were 15.0% during 2017 and 2018. Conclusions and Relevance The study results suggest that in contrast to the continued increase in North America, isothiazolinone allergy is decreasing in Europe. This trend may coincide with earlier and more stringent government regulation of MI in Europe.
Pain affects every fifth adult worldwide and is a significant health problem. From a physiological perspective, pain is a protective reaction that restricts physical functions and causes responses in physiological systems. These responses are accessible for evaluation via recorded biosignals and can be favorably used as feedback in active pain therapy via auricular vagus nerve stimulation (aVNS). The aim of this study is to assess the significance of diverse parameters of biosignals with respect to their deflection from cold stressor to deep breathing and their suitability for use as biofeedback in aVNS stimulator. Seventy-eight volunteers participated in two cold pressors and one deep breathing test. Three targeted physiological parameters (RR interval of electrocardiogram, cardiac deflection magnitude Z AC of ear impedance signal, and cardiac deflection magnitude PPG AC of finger photoplethysmogram) and two reference parameters (systolic and diastolic blood pressures BP S and BP D) were derived and monitored. The results show that the cold water decreases the medians of targeted parameters (by 5.6, 9.3%, and 8.0% of RR, Z AC, and PPG AC, respectively) and increases the medians of reference parameters (by 7.1% and 6.1% of BP S and BP D, respectively), with opposite changes in deep breathing. Increasing pain level from relatively mild to moderate/strong with cold stressor varies the medians of targeted and reference parameters in the range from 0.5% to 6.0% (e.g., 2.9% for RR, Z AC and 6.0% for BP D). The physiological footprints of painful cold stressor and relaxing deep breathing were shown for auricular and non-auricular biosignals. The investigated targeted parameters can be used as biofeedback to close the loop in aVNS to personalize the pain therapy and increase its compliance.
The study aims to assess the role of social support, sociocultural adjustment, and other social and demographic factors in international students' mental health. In total, 193 international first-year students studying Health and Technology Sciences in Lithuania filled out a self-report questionnaire. The study revealed that overall 59% of international students had symptoms of depression and 36%—of anxiety. Students' well-being was sufficient in 56% of the cases. The regression analyses were conducted to test the role of sociocultural adjustment, social support, English reading skills, and the study field for mental health and well-being. The multivariate regression model revealed that sociocultural adjustment is a stronger predictor compared to social support for depressiveness (βs = 0.42), anxiety (βs = 0.30), psychosomatic symptoms (βs = − 0.24), and subjective health (βs = 0.16), though social support was a stronger independent predictor for well-being (βs = 0.37). Moreover, sociocultural adjustment and social support were stronger predictors than gender, while English reading skills and study field were non-significant indicators.
Background: In addiction medicine training, self-assessment is increasingly used to support self-regulation learning by identifying standards of excellence, competence gaps, and training needs. To ensure psychiatrists in Lithuania also develop specific addiction competencies, the Lithuanian Health Sciences University faculty in Kaunas developed an addiction psychiatry curriculum. Objectives: The aim of this research is to explore the efficacy of the AM-TNA scale to measure individual and group differences in proficiency in the core competencies of addiction medicine. A cross-sectional study and a convenience sample were used. Method: We studied the differences in performance in addiction medicine competencies between 4 successive year groups and analysed the variance to determine the statistical differences between the means of 4 year groups with biases, resulting from repeated measurement statistically corrected-for. Results: Of the psychiatrists in training, 41% or 59% completed the scale. The assessment of competencies suggested that all but 2 competencies differ significantly (p < 0.05) between the 4 groups. The post hoc analyses indicated that mean scores for 24 of the 30 core competencies differed significantly between the year groups (p < 0.05) and showed a gradual increase in scores of self-assessed competencies over the 4 year groups. We found adequate scale variance and a gradual increase in self-assessed competencies between the 4 year groups, suggesting a positive association between the results of incremental professional training and improved self-assessed substance use disorders (SUD) competency scores. Conclusions: This study illustrates the efficacy of the AM-TNA scale as an assessment instrument in a local training context. Future research should aim to have larger sample sizes, be longitudinal in design, assess individual progress, and focus on comparing and combining self-reported competencies with validated objective external assessment and feedback.
Background. Electrical injuries are not common, however these injuries are severe. The burns cause damage for both superficial and deep layers of skin, as well as deeper tissues, and can lead to necrosis. Morbidity and mortality from electrical injuries are quite high and have physical and psychological consequences. Epidemiological analysis of electrical burns helps to understand patterns of these devastating injuries and to plan further treatment strategies. The objective of the study is to evaluate the number of patients affected by electrical injuries in Lithuania from 2016 to 2020. Methods. Data for the study were used from the Health Information Center of the Institute of Hygiene, calculated from the information system SVEIDRA of the State Health Insurance Fund under the Ministry of Health of Lithuania. Statistical analysis of the data was performed using IBM SPSS statistics 23.0 software. Using the Mann-Whitney criterion, a comparison was made between the percentage distributions of electrical injuries during the study period. Results. During five years (2016–2020), 355 peop­le in total, 85 of them children, were affected by electrical injuries. Men were more likely to suffer from electric injuries. 80.4 percent males were affected and 19.6 percent females. Overall, electrical injuries decreased by 8.45 percent. The number of electrical injuries decreased by 3.66% in the children group and 4.79% in the adult group. Conclusions. After reviewing the research data, it can be concluded that from 2016 to 2020, there was decreased tendency of electrical injuries in Lithuania by 15.3% among children and by 6.29% among adults. Men were more likely to experience electrical injuries. Ongoing prevention strategies and measures in society and raising social awareness are key factors in reducing electrical injuries.
Background Taxation increases which reduce the affordability of alcohol are expected to reduce mortality inequalities. A recent taxation increase in Lithuania offers the unique possibility to test this hypothesis. Methods Census-linked mortality data between 2011 and 2019 were used to calculate monthly sex- and education-stratified age-standardized mortality rates for the population aged 40 to 70 years. As primary outcome, we analysed the difference in age-standardized all-cause mortality rates between the population of lowest versus highest educational achievement. The impact of the 2017 taxation increase was evaluated using interrupted time series analyses. To identify whether changes in alcohol use can explain the observed effects on all-cause mortality, the education-based mortality differences were then decomposed into n = 16 cause-of-death groupings. Results Between 2012 and 2019, education-based all-cause mortality inequalities in Lithuania declined by 18% among men and by 14% among women. Following the alcohol taxation increase, we found a pronounced yet temporary reduction of mortality inequalities among Lithuanian men (− 13%). Subsequent decomposition analyses suggest that the reduction in mortality inequalities between lower and higher educated men was mainly driven by narrowing mortality differences in injuries and infectious diseases. Conclusions A marked increase in alcohol excise taxation was associated with a decrease in mortality inequalities among Lithuanian men. More pronounced reductions in deaths from injuries and infectious diseases among lower as compared to higher educated groups could be the result of differential changes in alcohol use in these populations.
