Substance use and its association with mental health among Swiss medical students: A cross-sectional study.

Background: Studies on mental health and substance use among medical students indicated worrying prevalence but have been mainly descriptive.

Aim: To evaluate the prevalence of substance use in a sample of medical students and investigate whether mental health variables have an influence on substance use.

Methods: The data were collected as part of the first wave of the ETMED-L, an ongoing longitudinal open cohort study surveying medical students at the University of Lausanne (Switzerland).

Subtypes of major depressive disorders and objectively measured physical activity and sedentary behaviors in the community.

Background: Lack of physical activity (PA) and high sedentary behavior (SB) may enhance mental health problems, including depression, and are associated with increased mortality. Aside from a large body of research on major depressive disorder (MDD) assessed as an entity and either PA or SB, few studies have examined associations among subtypes of MDD and both PA and SB simultaneously derived from wrist-worn accelerometers. Accordingly, our aim was to explore the associations among MDD subtypes (atypical, melancholic, combined atypical-melancholic and unspecified) and four actigraphy-derived behaviors combining the levels of PA and SB.

[Psychiatric dimensions of post-COVID-19 condition : an overview].

In the aftermath of the SARS-CoV-2 pandemic, many patients developed a set of persistent and disabling symptoms, commonly referred to as "long COVID" and defined as "post-COVID-19 condition" by the World Health Organization. The multi-systemic impairments caused by this condition include neuropsychiatric symptoms characterized by the presence of fatigue, cognitive and sleep disturbances, and increased rates of mood and anxiety disorders. Despite their high incidence and a significant risk of chronicity, they remain poorly understood.

[Multidisciplinary assessment and management of neurocognitive complaints in people living with HIV].

Current recommendations for the management of neurocognitive complaints in people living with HIV (PLWH) include a series of evaluations that may start with the exclusion of depression followed by a stepwise approach comprised by neurological, neuropsychological and psychiatric assessment, alongside the performance of an MRI and a lumbar puncture. This extensive evaluation is time demanding, and face PLHW with multiple medical consultations and waiting lists. As a response to these challenges, we have developed a one-day Neuro-HIV platform where PLWH undergo a state of the art multidisciplinary assessment in order to provide the necessary diagnoses and interventions to improve their quality of life.
