Background: Emerging issues in the management of major depressive disorder (MDD) comprise a nonadherence to treatment and treatment failures, depressive recurrence and relapses, misidentification of incoming exacerbated phases and consequently, a chronification of depression. While antidepressant drugs constitute the standard of care for MDD, effective psychosocial interventions are needed to reduce rehospitalizations and other adverse events. The present study primarily investigated the effects and impact of implementing a structured psychoeducational intervention on the clinical course of MDD., Methods: A non-randomized comparative, pragmatic, pilot, single-center study of adults with nonpsychotic moderate or severe episode of MDD recently discharged from a psychiatric hospitalization. The consecutive subjects were allocated either to the intervention group ( N =49) or to the attention control group ( N =47), based on their preference. The psychoeducational intervention was based on a modified Munoz's Depression Prevention Course. Subjects were followed up prospectively for two years., Results: The absolute changes in Beck anxiety inventory scale, Zung's depression questionnaire, and Montgomery and Äsberg depression rating scale (MADRS) total scores at 6-month follow-up were comparable between the two groups. There were lower rates of the rehospitalization within one year (2.1% vs. 16.7%; P <0.001) and less rehospitalizations after one year (6.3% vs. 25%; P <0.001), lower rates of the ongoing sickness absence (11.5% vs. 29.2%; P <0.001), less persons with disability due to MDD at 1-year follow-up (1% vs. 11.5%; P =0.002), and less nonadherent subjects who self-discontinued treatment (6.3% vs. 28.1%; P <0.001) among participants in the intervention group compared to the control group. The disability due to MDD at 1-year follow-up was predicted by the absence of the psychoeducational intervention ( P =0.002) and by the MADRS total score at 6-month follow-up (OR 1.10; 95% CI 1.003-1.195; P =0.044). Qualitative data indicated the intervention was desired and appreciated by the participants, as well as being practical to implement in Slovakian clinical settings., Conclusion: The results suggest the psychoeducational intervention based on a modified Munoz's Depression Prevention Course has beneficial effects in adults with MDD recently discharged from a psychiatric hospitalization. The findings implicate the psychoeducational intervention may offer a new approach to the prevention of depressive relapses., Competing Interests: The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest., (Copyright © 2024 Breznoscakova, Pallayova, Izakova and Kralova.)

Alzheimer's disease (AD) is an age-related neurodegenerative disorder characterised by progressive loss of memory. In the AD brain, matrix metalloproteinases (MMPs) are involved in the disruption of the blood-brain barrier resulting in a neuroinflammatory response. The objective of our investigation was to assess the association of MMP2 rs243866 and rs2285053 polymorphisms with susceptibility to AD, to assess the interaction of MMP2 variants with APOE ε4 risk allele, and to evaluate their influence on the age at disease onset and MoCA score. A total of 215 late-onset AD patients and 373 control subjects from Slovakia were genotyped for MMP2 rs243866 and rs2285053 polymorphisms. The MMP2 association with AD risk and clinical parameters was evaluated by logistic and linear regression analyses. No statistically significant differences in either MMP2 rs243866 and rs2285053 allele or genotype frequencies between AD patients and the control group have been observed ( p > 0.05). However, the correlation with clinical findings revealed a higher age at disease onset in MMP2 rs243866 GG carriers in the dominant model as compared to other MMP2 genotype carriers ( p = 0.024). Our results suggest that MMP2 rs243866 promoter polymorphism may have an impact on the age at AD onset in the patients.

Fecal microbiota transfer may serve as a therapeutic tool for treating obesity and related disorders but currently, there is no consensus regarding the optimal donor characteristics. We studied how microbiota from vegan donors, who exhibit a low incidence of non-communicable diseases, impact on metabolic effects of an obesogenic diet and the potential role of dietary inulin in mediating these effects. Ex-germ-free animals were colonized with human vegan microbiota and fed a standard or Western-type diet (WD) with or without inulin supplementation. Despite the colonization with vegan microbiota, WD induced excessive weight gain, impaired glucose metabolism, insulin resistance, and liver steatosis. However, supplementation with inulin reversed steatosis and improved glucose homeostasis. In contrast, inulin did not affect WD-induced metabolic changes in non-humanized conventional mice. In vegan microbiota-colonized mice, inulin supplementation resulted in a significant change in gut microbiota composition and its metabolic performance, inducing the shift from proteolytic towards saccharolytic fermentation (decrease of sulfur-containing compounds, increase of SCFA). We found that (i) vegan microbiota alone does not protect against adverse effects of WD; and (ii) supplementation with inulin reversed steatosis and normalized glucose metabolism. This phenomenon is associated with the shift in microbiota composition and accentuation of saccharolytic fermentation at the expense of proteolytic fermentation.

Background: Population's mental health surveillance is essential for knowing the distribution of mental well-being and mental disorders in the society. This allows for the establishment, evaluation, and revision of preventive measures and curative services. The results of such monitoring should serve as a database for evidence-based mental health policy. Mental disorders are among the top ten causes of burden globally and crisis situations such as the pandemic increase the risk of mental health problems, as they cause constant fear of contagion and the implementation of restrictive measures. The impact of the coronavirus disease 2019 (COVID-19) pandemic on the general population of the Slovak Republic has not yet been studied. The hypothesis was that more than one fifth of the population (women to a greater extent) will have symptoms of anxiety and depression., Aim: To assess the mental health of the general Slovak population aged 15 years and older in the summer of 2021 by determining the prevalence of depressive and anxiety symptoms., Methods: An anonymous cross-sectional survey was implemented in a sample of 1501 respondents in the summer of 2021 during the COVID-19 pandemic. The inclusion criteria were age of 15 years and older and ability to complete the survey questionnaire online or in a face-to-face interview. The survey assessed anxiety symptoms by the seven-item general anxiety disorder and depressive symptoms by the nine-item patient health questionnaire instruments. Recognized cut-off scores of 10 or greater were used for both., Results: Anxiety symptoms were present in 19.32% and depression in 24.65% of the sample. Symptoms of both disorders were more common in females: 15.00% of males and 24.00% of females experienced anxiety symptoms, and 19.00% of males and 30.00% of females experienced symptoms of depression. Symptoms of both disorders were the most common in the youngest age group (15-25 years old): One fifth of males (20.29%) and one third of females (35.32%) had symptoms of anxiety, and 26.09% males and 43.79% females had symptoms of depression. Mean score for anxiety was 5.44 [standard deviations (SD) = 4.96] for the overall sample, 6.15 (SD = 5.14) for females, and 4.67 (SD = 4.63) for males. The youngest females of the 15-25 years age group had the highest score (7.55, SD = 5.27) among all age groups, for both sexes. Mean score for depression was 6.74 for the overall sample (SD = 5.75), 7.43 for females (SD = 5.87), and 5.99 (SD = 5.52) for males. The highest depression score was observed in the youngest females of the 15-25 years age group (9.34, SD = 6.07). We found a significant association between anxiety or depressive symptoms and younger age [odds ratio (OR): 1.69, 95% confidence interval (CI): 1.16-2.45 and OR: 1.65, 95%CI: 1.17-2.34, respectively], being female (OR: 1.86, 95%CI: 1.42-2.42 and OR: 1.76, 95%CI: 0.20-0.29, respectively), and having primary education (OR: 1.66, 95%CI: 1.08-2.54 and OR: 1.65, 95%CI: 1.16-2.63, respectively)., Conclusion: Results of our study indicate that anxiety and depression are frequent in the Slovak Republic during the COVID-19 pandemic. This important observation should serve as an information basis for the development of effective mental health policies, consisting of preventive programs, and early detection and effective treatment services. The study results provide strong argument for the necessity of mental health reform that is currently being shaped in the Slovak Republic., Competing Interests: Conflict-of-interest statement: There are no conflicts of interest to report., (©The Author(s) 2022.

Background and Aim: Plant-based diets are associated with potential health benefits, but the contribution of gut microbiota remains to be clarified. We aimed to identify differences in key features of microbiome composition and function with relevance to metabolic health in individuals adhering to a vegan vs. omnivore diet. Methods: This cross-sectional study involved lean, healthy vegans ( n = 62) and omnivore ( n = 33) subjects. We assessed their glucose and lipid metabolism and employed an integrated multi-omics approach (16S rRNA sequencing, metabolomics profiling) to compare dietary intake, metabolic health, gut microbiome, and fecal, serum, and urine metabolomes. Results: The vegans had more favorable glucose and lipid homeostasis profiles than the omnivores. Long-term reported adherence to a vegan diet affected only 14.8% of all detected bacterial genera in fecal microbiome. However, significant differences in vegan and omnivore metabolomes were observed. In feces, 43.3% of all identified metabolites were significantly different between the vegans and omnivores, such as amino acid fermentation products p-cresol, scatole, indole, methional (lower in the vegans), and polysaccharide fermentation product short- and medium-chain fatty acids (SCFAs, MCFAs), and their derivatives (higher in the vegans). Vegan serum metabolome differed markedly from the omnivores (55.8% of all metabolites), especially in amino acid composition, such as low BCAAs, high SCFAs (formic-, acetic-, propionic-, butyric acids), and dimethylsulfone, the latter two being potential host microbiome co-metabolites. Using a machine-learning approach, we tested the discriminative power of each dataset. Best results were obtained for serum metabolome (accuracy rate 91.6%). Conclusion: While only small differences in the gut microbiota were found between the groups, their metabolic activity differed substantially. In particular, we observed a significantly different abundance of fermentation products associated with protein and carbohydrate intakes in the vegans. Vegans had significantly lower abundances of potentially harmful (such as p-cresol, lithocholic acid, BCAAs, aromatic compounds, etc.) and higher occurrence of potentially beneficial metabolites (SCFAs and their derivatives)., Competing Interests: The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest., (Copyright © 2022 Prochazkova, Budinska, Kuzma, Pelantova, Hradecky, Heczkova, Daskova, Bratova, Modos, Videnska, Splichalova, Sowah, Kralova, Henikova, Selinger, Klima, Chalupsky, Sedlacek, Landberg, Kühn, Gojda and Cahova.)

Alzheimer's disease (AD) is a chronic neurodegenerative disease of the central nervous system with higher prevalence in elderly people. Despite numerous research studies, the etiopathogenesis of AD remains unclear. Matrix metalloproteinases (MMPs) are endopeptidases involved in the cleavage of extracellular matrix proteins and basement membrane compounds. In the brain, the pathological role of MMPs includes the disruption of the blood-brain barrier leading to the induction of neuroinflammation. Among various MMPs, MMP-2 and MMP-3 belong to candidate molecules related to AD pathology. In our study, we aimed to evaluate the association of MMP2 rs243865 and MMP3 rs3025058 polymorphisms with AD susceptibility and their influence on age at onset and MoCA score in patients from Slovakia. Both MMP gene promoter polymorphisms were genotyped in 171 AD patients and 308 controls by the PCR-RFLP method. No statistically significant differences in the distribution of MMP2 rs243865 (-1306 C>T) and MMP3 rs3025058 (-1171 5A>6A) alleles/genotypes were found between AD patients and the control group. However, correlation with clinical findings revealed later age at disease onset in MMP2 rs243865 CC carriers in the dominant model as compared to T allele carriers (CC vs. CT+TT: 78.44 ± 6.28 vs. 76.36 ± 6.39, p = 0.036). The results of MMP3 rs3025058 analysis revealed that 5A/6A carriers in the overdominant model tended to have earlier age at disease onset as compared to other MMP3 genotype carriers (5A/6A vs. 5A/5A+6A/6A: 76.61 ± 5.88 vs. 78.57 ± 6.79, p = 0.045). In conclusion, our results suggest that MMP2 rs243865 and MMP3 rs3025058 promoter polymorphisms may have influence on age at onset in AD patients., Competing Interests: The authors report no conflict of interests., (Copyright © 2021 Vladimira Durmanova et al.)

Objectives: The aim of our study was to examine the role of low density lipoprotein (LDL)-subfractions in individuals with the atherogenic and non-atherogenic phenotype and the gender differences in lipoprotein subfractions including small dense LDL (sdLDL) and small high density lipoprotein (sHDL) subfractions representing the most atherogenic lipoprotein subfractions., Design & Methods: 35 persons in the atherogenic group (AG) (with sdLDL 3-7 subfractions ≥6 mg/dl) and 104 individuals in the non-atherogenic group (NAG) (sdLDL 3-7 subfractions <6 mg/dl) were included in our study. To analyze plasma lipoprotein subfractions, a polyacrylamide gel electrophoresis-the Lipoprint system was used., Results: Males compared to females in the AG had significantly higher levels of atherogenic lipoprotein subfractions such as HDL 8, HDL 9 and HDL 10 . All participants in AG had significantly lower levels of intermediate density lipoprotein IDL-A than those in NAG but significantly higher levels of IDL-B and IDL-C. Males in the AG compared to NAG had significantly lower levels of LDL 1 and higher levels of LDL 2 and LDL 3-7 subfractions. In the NAG LDL 2 positively correlated with sHDL subfractions while in the AG with the large HDL subfraction., Conclusion: Results of our study demonstrate more atherogenic profile in males compared to females and a double role of LDL2 subfraction in the atherogenic process depending on the phenotype (atherogenic/non-atherogenic) of individuals., Competing Interests: Declaration of Competing Interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2020 The Canadian Society of Clinical Chemists.

Objectives: Theory of Mind (ToM), the ability to understand other people's mental states, is essential in everyday social interactions. The relationship between cognitive domains and ToM impairment in Parkinson disease (PD) has been receiving growing attention with ambiguous findings. The objective of the current study was to ascertain which cognitive domain predicts understanding of intentions and the impact of PD-specific clinical measures on ToM performance. A secondary aim was to evaluate whether cognitive impairment mediates the relationship between severity of illness and ToM impairment., Methods: Fifty-one nondemented patients with idiopathic PD, ranging from early to advanced stages, were enrolled. A comprehensive neurocognitive battery and 2 ToM tasks (Hinting Task and Comic Strip Task) were administered during the patients' best "on" medication state., Results: Only the task of measuring working memory capacity was significantly associated with both ToM tasks (Hinting Task Spearman rank correlation [ rs] = 0.309, P ≤ .05; Comic Strip Task rs = 0.595, P ≤ .01). Patients with more progressed disease and higher doses of dopaminergic medication performed significantly worse in the Comic Strip Task. Based on the mediation analysis, relationship between the severity of the illness and understanding of intentions was mediated by cognitive flexibility., Conclusion: In PD, understanding of intentions is related to neurocognition, with working memory and cognitive flexibility playing a crucial role. The severity of PD predicts ToM performance.

Alzheimer's disease (AD) is the most prevalent cause of dementia in elderly people worldwide. Many studies support the hypothesis that the inflammation of the CNS contributes to the neurodegeneration and disease progression. The integrin molecule α 4 β 1, also known as very late antigen 4 (VLA-4), belongs to adhesion molecules that activate the inflammatory process through the migration of immune cells into the CNS. Therefore, the objective of our study was to analyze the association between two polymorphisms located in the ITGA4 gene encoding the α 4 subunit of VLA-4 and the risk of AD. 104 late-onset AD patients and 206 control subjects from Slovakia were genotyped for ITGA4 gene SNP polymorphism rs113276800 (-269C/A) and rs1143676 (+3061A/G). The same study cohorts were also genotyped for the APOE - ε 4, which is a known genetic factor associated with increased risk of AD developing. ITGA4 polymorphism analysis revealed significantly higher frequency of the +3061AG carriers in AD group compared to the controls ( P ≤ 0.05). Following the APOE - ε 4 stratification of study groups, the association remained significant only in APOE - ε 4 noncarriers. Our study suggests a novel association of ITGA4 +3061A/G polymorphism with AD and its possible contribution to the disease pathology.

Background/aims: Dementia and psychiatric disorders are common in assisted living facilities (ALFs) and have suboptimal rates of recognition and treatment. Therefore, we aimed to obtain a direct estimate of the prevalence of cognitive impairment and especially dementia among residents of ALFs in western Slovakia and their rates of primary recognition and adequate treatment., Methods: We conducted two cross-sectional studies. Ten ALFs within the city of Bratislava were chosen for the study in 2004, and again in 2011. A total of 866 residents in ALFs were examined in 2004, and 821 residents in ALFs were examined in 2011. The rate and characterization of dementia, its primary recognition and adequate treatment were investigated in both cross-sectional studies., Results: In 2004, 57% of the participants had dementia. Only 7.2% of the participants with probable Alzheimer disease were treated with acetylcholinesterase inhibitors. In 2011, we observed a significant improvement in primary diagnostics and therapy. 66.9% of the cases of dementia were adequately evaluated, and 52.1% were adequately treated., Conclusion: Cognitive deficit and dementia are significantly underdiagnosed and undertreated in assisted living settings. In the second cross-sectional study we detected significant but not complete improvement in the primary recognition and adequate therapy of dementia., (© 2018 S. Karger AG, Basel.)
