A chronotype is generally defined as the variability of the phase angle of entrainment, while the latter reflects the relationship between the timing of a certain rhythm (e.g., the sleep–wake cycle) and the timing of an external temporal cue. Individuals can be placed on a spectrum from "morning types" (M types) to "evening types" (E types). E-chronotype has been proposed as a transdiagnostic risk factor for psychiatric conditions, and it has been associated with psychopathological dimensions. Eveningness seems to be correlated with both suicidal ideation (SI) and suicidal behavior (SB) through several possible mediating factors. Immunological alterations have also been linked to later chronotypes and SI/SB. This narrative review aims to summarize the evidence supporting the possible association between chronotypes and suicide and the eventual mediating role of neuroinflammation and several psychopathological dimensions. A search of the literature (2003–2023) was conducted using various databases: PUBMED, EMBASE, Scopus, UpToDate, PsycINFO, and Cochrane Library. English-language articles were collected and screened for eligibility. Despite the apparent absence of a direct correlation between E-chronotype and suicidality, E-chronotype promotes a chain of effects that could be involved in an increased risk of SB, in which with neuroinflammation possibly plays an intriguing role and some psychopathological dimensions may stand out.

Due to the rapid spread of the novel coronavirus pandemic, a reorganization of the health care sector was needed. Many questions arose concerning the specificity of psychiatric care in this unprecedented situation. In Geneva, Switzerland, the department of psychiatry decided to open a new ward for its infected patients. Beyond the challenge of setting it up quickly, we faced the challenges of taking care of a heterogeneous group of patients and of incorporating protection measures we were not accustomed to, which add a significant amount of time to the daily care of patients. The staff recruitment on a voluntary basis, close supervision, availability of the personal protective material as well as support from the infection prevention and control unit have enabled proper functioning of the ward., Competing Interests: Les auteurs n’ont déclaré aucun conflit d’intérêts en relation avec cet article.
