Estimation of Years Lived with Disability Using a Prevalence-Based Approach: Application to Major Psychiatric Disease in Korea

The P2X7 receptor in mood disorders: Emerging target in immunopsychiatry, from bench to bedside

Psychiatric disorders are among the most burdensome disorders worldwide. Though therapies have evolved over the last decades, treatment resistance still affects many patients. Recently, neuroimmune systems have been identified as important factors of mood disorder biology. The underlying dysregulation in neuroimmune cross-talk is driven by genetic risk factors and accumulating adverse environmental influences like chronic psychosocial stress. These result in a cluster of proinflammatory cytokines and quantitative and functional changes of immune cell populations (e.g., microglia, monocytes, T cells), varying by disease entity and state. Among the emerging immune targets, purinergic signalling revolving around the membranous and ATP specific P2X7 receptor (P2X7R) has gained wider attention and clinical studies making use of antagonistic drugs are on-going. Still, no clinically meaningful applications have been identified so far. A major problem is the often overly simplified approach taken to translate findings from bench to bedside. Therefore, the present review focuses on purinergic signalling via P2X7R in the context of recent advances in immunopsychiatric mood disorder research. Our aim is to provide an overview of the current P2X7R-related findings, from bench to bedside. First, we summarize the characteristics of purinergic signalling and P2X7R, followed by a depiction of genetic and clinical data connecting P2X7R to mood disorders. We close with our perspective on current developments and discuss changes necessary to translate the evident potential of P2X7R signalling modulation into meaningful clinical application. This article is part of the Special Issue on 'Purinergic Signaling: 50 years'.

Disability Weights and Years Lived with Disability of Depression with and Without Suicidality

Background

Globally, depression is a silent epidemic, and more than 350 million people suffer from depression. For a long time, the belief prevailed that children and young people cannot suffer from depressive disorders, and depression is slowly becoming one of the leading health problems among the young population.

Objective

This research aims to determine the mental health disorders burden attributed to depression, anxiousness, and fear with and without suicidal ideation among youth in Bosnia and Herzegovina.

Methods

A prospective cross-sectional study was performed as screening of depression by Hamilton standardized screening instrument from May 3, 2018, to April 4, 2019, among young people, students in secondary schools, and the Faculty of Pharmacy and Medical Faculty of the University of Tuzla in the most populous Tuzla Canton in the Federation of Bosnia and Herzegovina. In achieving the research goals, we expressed the burden attributed to depression with and without suicidality, anxiousness, and fear as Disability Weight (DW) and Years Lived with Disability (YLD). For the population level, YLD was calculated by multiplying DW by the prevalence rate of depression, anxiousness, and fear per thousand of the population (YLD= DW x prevalence/1000), and DW was adjusted for suicidality.

Results

The participants' ages ranged from 16 to 24 years, with a mean of 20,6 ± 1,9 years. The Body mass index (BMI) of 21,9 ± 2,7 is the recommended reference value of 18.5-24.9 kg/m2. The depression score of all participants ranged from 0 to 32 with a mean of 7.4± 6.3, which for our population of respondents at the sample level implies entry into the zone of presence of depressive symptoms. Descriptive statistics and differences per gender in sociodemographic variables (age, education state, and secure monthly existence); and modified factors attributed to satisfaction needs (life satisfaction, hope for the future, support from person of influence). Most participants belong to the age group 19-21 years, 71,44% (n=180), and the same 14,28% (n=36) other age groups (16-18 and 22-24 years), and sixty-two percent of participants are university students, and twenty percent are university failures.

Conclusion

Based on our findings, the very high burden of depression in Bosnia and Herzegovina was found greatly not recognized and unsolved problem among the young population aged 16-24 years. Recognizing and screening depression in young people is the first step to prevention.

Exploring the trend of Schizophrenia at Hiwot Fana specialized university referral hospital, Eastern, Ethiopia (2016-2020): A 5-year retrospective analysis

Schizophrenia is one of the most troublesome psychiatric problems requiring long-term antipsychotic treatments. There is a scarcity of data regarding its overtime trend in Ethiopia.
