Introduction: Irritable Bowel Syndrome (IBS) is a chronic gastrointestinal disorder affecting a substantial portion of the global population. While the prevalence of IBS is well-documented worldwide, limited research has explored its occurrence and associated factors among medical students in Bangladesh, a population exposed to high academic stress. This cross-sectional study aimed to assess the prevalence of IBS among medical students and investigate its potential association with stress levels and the dormitory lifestyle. Methods: Data were collected from 402 medical students using a self-administered questionnaire covering sociodemographic information, academic stress, lifestyle factors, and the Rome III Criteria for diagnosing IBS. Statistical analysis included bivariate and logistic regression analyses to identify significant associations and predictors of IBS prevalence. Results: This study among 402 university students found an overall irritable bowel syndrome (IBS) prevalence of 22.88 %, with 35.87 % diarrhea-predominant, 26.08 % constipation-predominant, and 38.04 % mixed subtype. Hostel residents had 2.11 times higher adjusted odds of IBS (95 % CI: 1.05–4.25, p 3 years of hostel stay. Age 23–28 years (OR = 1.86, p = 0.030), lack of senior support (OR = 2.36, p = 0.05), second study phase (OR = 2.43, p = 0.002), inadequate exercise (OR = 2.11, p = 0.036), and frequent fatty food intake (OR = 2.98, p = 0.03) increased IBS risk. Higher academic stress (OR = 2.03, p = 0.002) predicted IBS, with 54.44 % vs. 43.78 % (p = 0.035) high stress among hostel residents who exercised less (48.23 % vs. 51.77 %) and consumed more fatty foods (53.33 % vs. 46.67 %). Mediation analysis revealed dormitory living impacts stress, physical activity, and diet - established IBS risk factors. Conclusion: The high prevalence of IBS among medical students in Bangladesh highlights the need for interventions to address changeable factors like academic stress, dormitory living conditions, lack of physical activity, and unhealthy eating habits to improve their health and wellness.

As major depressive disorder (MDD) is such a diverse condition, there are currently no clear ways for determining its severity, endophenotype, or therapy response. The distinctive nature of depression, the variability of analysis in literature and the large number of conceptually complicated biomarkers are some of the many reasons for the lack of progress. Markers are involved in the process of neurotrophic, metabolic, and inflammation as well as neuroendocrine and neurotransmitter systems’ components. Some clinical indicators are strong enough so that can be measured using assessments of proteomic, genetic, metabolomics, neuroimaging, epigenetic and transcriptomic. Markers of oxidative stress, endocrine, inflammatory, proteomic, and growth indicators are currently among the promising biologic systems/markers identified in this analysis. This narrative review examines succinct studies which investigated cytokines of inflammatory factors, peripheral factors of development, metabolic and endocrine markers as pathophysiological biomarkers of MDD, and treatment responses. Endocrine and metabolic alterations have also been linked to MDD in various studies. So, this study summarizes all of the numerous biomarkers that are significant in the detection or treatment of MDD patients. The paper also provides an overview of various biomarkers which are important for the regulation and its effects on MDD.

Background: The COVID-19 outbreak spillovers mental health burden where suicide is a common psychological public health issue that affects people all over the world. This study aimed to explore the factors associated with suicidal behavior among university students in Bangladesh after one year of the COVID-19 outbreak. Methods: An online cross-sectional survey was conducted among 2100 Bangladeshi university students aged ≥18 years from April 29 to May 15, 2021. The survey questionnaire contained socio-demographic information, COVID-19 related physical and psychosocial factors (CRPPF), preventive response to psychological stress, and the Suicidal Behaviors Questionnaire-Revised (SBQ-R) scale. Descriptive statistics along with logistic regression were performed for statistical analysis. Results: About 47.90% of the students were at risk of suicidal behavior, and female students were very likely to be at risk of suicidal behavior than their male counterparts (AOR = 2.28; 95% CI: 1.86 to 2.81). Keeping distance from friends or family (AOR = 1.66; 95% CI: 1.34 to 2.04), having relationship problems (AOR = 2.20; 95% CI: 1.79 to 2.70), feeling own selves as burden to families (AOR = 2.50; 95% CI: 2.02 to 3.11), and being stressed of lockdown (AOR = 1.56; 95% CI: 1.19 to 2.03) were highlighted as some of the significant factors associated with increased risk of suicidal behavior. Conclusion: University students were exposed to several factors that impose the risk of developing suicidal behavior. Concerned authorities should design & implement appropriate strategies for ensuring suicidal prevention besides their mental well-being.
