In their study, Stavropoulos et al. (2023) capitalized on supervised machine learning and a longitudinal design and reported that the User-Avatar Bond could be accurately employed to detect Gaming Disorder (GD) risk in a community sample of gamers. The authors suggested that the User-Avatar Bond is a “digital phenotype” that could be used as a diag...

Background While beta-blockers have been shown to improve outcomes after acute coronary syndromes (ACS), most trials predate the advent of reperfusion therapy and modern secondary prevention. Recent trial data in the reperfusion era found no all-cause or cardiovascular mortality benefit in patients with a left ventricular ejection fraction (LVEF) >...

Aims The benefit of long-term beta-blocker therapy after acute coronary syndromes (ACS) without heart failure in the reperfusion era is uncertain. Two recent randomized trials found conflicting results. The present study assessed the safety of beta-blocker discontinuation within 12 months following ACS with LVEF ≥40%. Methods In a multicentre pros...

Aims Healthcare staff use coercive measures to manage patients at acute risk of harm to self or others, but their effect on patients’ mental health is underexplored. This nationwide Swiss study emulated a trial to investigate the effects of coercive measures on the mental health of psychiatric inpatients at discharge. Methods We analysed retrospe...

(Abstracted from N Engl J Med 2024;390:601–610 In a recent systematic review of randomized controlled trials (RCTs), e-cigarettes were found to be more effective for tobacco smoking cessation than nicotine replacement therapy (NRT). Yet, limited evidence exists on the safety and efficacy of e-cigarettes over standard-of-care cessation counseling an...

Introduction. Robust empirical data on suicide awareness are needed, to better plan and evaluate suicide prevention interventions. However, there is a lack of validated measures of suicide awareness. This is especially true for perceived suicide awareness, which focuses on perceived knowledge about suicide, willingness, and confidence to talk about...

There is an important gap in health knowledge about vulnerable and hard-to-reach groups. The development of research projects and the implementation of interventions require strategies adapted to the particularities of these groups. This article reviews some of the main issues through the lens of recent projects conducted in French-speaking Switzer...

While applying a diagnostic approach (i.e., comparing “clinical” cases with “healthy” controls) is part of our methodological habits as researchers and clinicians, this approach has been particularly criticized in the behavioral addictions research field, in which a lot of studies are conducted on “emerging” conditions. Here we exemplify the pitfal...

Background: During the 2020/2021 winter, the labour market was under the impact of the COVID-19 pandemic. Changes in socioeconomic resources during this period could have influenced individual mental health. This association may have been mitigated or exacerbated by subjective risk perceptions, such as perceived risk of getting infected with SARS-...

The use of coercive practices, i.e., interventions against a person’s will, is controversial. Recent observational studies highlighted their potential detrimental effects on patients’ mental health, but this topic remains understudied. This study investigated the effect of a common coercive practice, seclusion (i.e., being locked in a closed room),...

Background Cyberchondria is characterized by repeated and compulsive online searches for health information, resulting in increased health anxiety and distress. It has been conceptualized as a multidimensional construct fueled by both anxiety and compulsivity-related factors and described as a “transdiagnostic compulsive behavioral syndrome,” which...

However, empirical evidence on the impact of the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) pandemic in prison is still scarce. This study aims to estimate the seroprevalence rates of anti-SARS-CoV-2 in the largest and most crowded Swiss prison and compare them with the s...

Importance: Few studies are available on informed consent (IC) among detained persons, even with ethics being a critical aspect of prison research. In IC research, audiovisual material seems to improve understanding and satisfaction compared with conventional paper-based material, but findings remain unclear. Objective: To compare audiovisual an...

The burden of mental health problems in detained persons is high. At the same time, mental health problems are discussed as possible predictors of criminal recidivism. During detention, mental health tends to improve. The aims of the study were twofold: First, to identify group-based trajectories of mental health problems over the course of detenti...

As on-demand streaming technology rapidly expanded, binge-watching (i.e., watching multiple episodes of TV series back-to-back) has become a widespread activity, and substantial research has been conducted to explore its potential harmfulness. There is, however, a need for differentiating non-harmful and problematic binge-watching. This is the firs...

The emergence of each novel SARS-CoV-2 variant of concern (VOC) requires investigation of its potential impact on the performance of diagnostic tests in use, including antigen-detecting rapid diagnostic tests (Ag-RDTs). Although anecdotal reports have been circulating that the newly emerged Omicron-BA.1 variant is in principle detectable by Ag-RDTs...

Background: The SARS-CoV-2 pandemic was particularly devastating for elderly people, and the underlying mechanisms of the disease are still poorly understood. In this study, we investigated fusion inhibitory antibodies (fiAbs) in elderly and younger COVID-19 patients and analyzed predictive factors for their occurrence. Methods: Data and samples...

AIMS OF THE STUDY: Suicide is one of the leading causes of death in young people. Therefore, suicide prevention in this age group is a public health priority. There is increasing evidence of the efficacy of suicide prevention programmes, but robust empirical studies are still needed. More precisely, data are needed for school-aged children, brief i...

People living in detention are at high risk of suicidal behaviour, with an incidence of suicides 3- to 9-fold higher compared to the general population. During the SARS-CoV-2 pandemic, suicidality among some disadvantaged populations increased and this trend was also observed in Swiss prisons. This article describes the clinical, psychosocial, inst...

Healthcare workers have potentially been among the most exposed to SARS-CoV-2 infection as well as the deleterious toll of the pandemic. This study has the objective to differentiate the pandemic toll from post-acute sequelae of SARS-CoV-2 infection in healthcare workers compared to the general population. The study was conducted between April and...

Objectives Serological assays for the presence of anti-SARS-CoV-2 antibodies are crucially needed for research and monitoring of the SARS-CoV-2 pandemic. Antibodies are reliability detected in capillary blood, a minimally invasive and cost-effective alternative to venous blood testing. However, there is a limited knowledge on feasibility of capilla...

The validity of the constructs of problematic Internet or smartphone use and Internet or smartphone addiction has been extensively debated. The spectrum hypothesis posits that problematic online behaviors (POBs) may be conceptualized within a spectrum of related yet distinct entities. To date, the hypothesis has received preliminary support, and fu...

Background: SARS-CoV-2 infection triggers different auto-antibodies, including anti-apolipoprotein A-1 IgGs (AAA1), which could be of concern as mediators of persistent symptoms. We determined the kinetics of AAA1 response over after COVID-19, and the impact of AAA1 on the inflammatory response and symptoms persistence. Methods: All serologies w...

The Pathological Narcissism Inventory (PNI) and the Narcissistic Personality Inventory (NPI) are often used to screen for pathological narcissism but have rarely been validated against a clinician-administered diagnostic interview. Our study evaluated the convergent validity of the PNI and NPI against a diagnostic interview for narcissistic persona...

This study investigated correlates of domestic homicide (DH) and other violent crimes. Data were collected retrospectively from criminal justice files on 617 persons in Switzerland (DH = 47).

Correctional officers adhered less to preventive measures than other staff memb...

Mis-diagnosis of attention deficit hyperactivity disorder (ADHD) is an important public health concern because the disease is treatable, yet can have a disastrous effect on the life of those affected. ADHD is associated with delinquency, criminality, and recidivism; and thus, people living in detention are especially at risk of having ADHD. This st...

Background: Our main objective was to provide estimates of the prevalence rates of psychiatric disorders and comorbidities among youths in a juvenile detention center in Geneva, Switzerland. We also aimed to investigate potential positive effects of intensive psychotherapeutic and educational services this center provides. Finally, we examined psyc...

To date, most of the evidence suggests that smoking is negatively associated with testing positive for SARS-CoV-2. However, evidence has several methodological limitations. Using an outpatient sample population, we analyzed the association of testing positive for SARS-CoV-2 and smoking considering comorbidities, socioeconomic and demographic factor...

Background: Oncological patients have a higher risk of prolonged SARS-CoV-2 shedding, which, in turn, can lead to evolutionary mutations and emergence of novel viral variants. The aim of this study was to analyze biological samples of a cohort of oncological patients by deep sequencing to detect any significant viral mutations. Methods: High-thr...

SARS-CoV-2 infection in children is less severe than in adults. We perform a longitudinal analysis of the early innate responses in children and adults with mild infection within household clusters. Children display fewer symptoms than adults despite similar initial viral load and mount a robust anti-viral immune signature typical of SARS-CoV-2 inf...

Background Nosocomial outbreaks of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) are frequent despite implementation of conventional infection control measures. We performed an outbreak investigation using advanced genomic and statistical techniques to reconstruct likely transmission chains and assess the role of healthcare workers (...
