[Sleep in a performance artist: Eight days and seven nights sitting inside a metal sculpture].

Sleep in extreme situations has been little studied. The artist Abraham Poincheval (AP) is known for his performances in confined spaces. For his show at the Perrotin Gallery in Paris, he was enclosed for 8days and 7nights in a metal sculpture of his body in a seated position, with his head facing a work by Hans Hartung at the end of a cone system placed in front of his eyes which occluded all other visual stimuli.

Management of obstructive sleep apnea syndrome type 1 in children and adolescents - A French consensus.

This document is the outcome of a group of experts brought together at the request of the French Society of Sleep Research and Medicine to provide recommendations for the management of obstructive sleep apnea syndrome type 1 (OSA) in children. The recommendations are based on shared experience and published literature. OSA is suspected when several nighttime respiratory symptoms related to upper airway obstruction are identified on clinical history taking.

Efficacy of melatonin and ramelteon for the acute and long-term management of insomnia disorder in adults: A systematic review and meta-analysis.

Melatonin has gained growing interest as a treatment of insomnia, despite contradictory findings, and a low level of evidence. A systematic review and meta-analysis was conducted following PRISMA criteria, to assess the efficacy of melatonin and ramelteon compared with placebo on sleep quantity and quality in insomnia disorder, while also considering factors that may impact their efficacy. This review included 22 studies, with 4875 participants, including 925 patients treated with melatonin, 1804 treated with ramelteon and 2297 receiving a placebo.

Posttraumatic stress disorder and depression after the 2018 Strasbourg Christmas Market terrorist attack: a comparison of exposed and non-exposed police personnel.

Police personnel are among the first responders exposed to terrorist attacks, raising in number in the late decades. Due to their profession, they are also exposed to repetitive violence, increasing their vulnerability to PTSD and depression. Our study aims at comparing the prevalence of PTSD and depression, and the risk factors associated with these conditions among directly and indirectly exposed versus non-exposed police personnel during the Strasbourg Christmas Market terrorist attack.

French Neonatal Society issues recommendations on preventing nasal injuries in preterm newborn infants during non-invasive respiratory support.

Aim: To issue practical recommendations regarding the optimal care of nasal skin when non-invasive ventilation support is used.

Methods: We performed a systematic search of PubMed to identify relevant papers published in English or French through December 2019. Different grades of evidence were evaluated.

Predictive biosignature of major depressive disorder derived from physiological measurements of outpatients using machine learning.

Major Depressive Disorder (MDD) has heterogeneous manifestations, leading to difficulties in predicting the evolution of the disease and in patient's follow-up. We aimed to develop a machine learning algorithm that identifies a biosignature to provide a clinical score of depressive symptoms using individual physiological data. We performed a prospective, multicenter clinical trial where outpatients diagnosed with MDD were enrolled and wore a passive monitoring device constantly for 6 months.

V-ATPase modulates exocytosis in neuroendocrine cells through the activation of the ARNO-Arf6-PLD pathway and the synthesis of phosphatidic acid.

Although there is mounting evidence indicating that lipids serve crucial functions in cells and are implicated in a growing number of human diseases, their precise roles remain largely unknown. This is particularly true in the case of neurosecretion, where fusion with the plasma membrane of specific membrane organelles is essential. Yet, little attention has been given to the role of lipids.

Pupillometry to differentiate idiopathic hypersomnia from narcolepsy type 1.

Idiopathic hypersomnia is poorly diagnosed in the absence of biomarkers to distinguish it from other central hypersomnia subtypes. Given that light plays a main role in the regulation of sleep and wake, we explored the retinal melanopsin-based pupil response in patients with idiopathic hypersomnia and narcolepsy type 1, and healthy subjects. Twenty-seven patients with narcolepsy type 1 (women 59%, 36 ± 11.

Light therapy in insomnia disorder: A systematic review and meta-analysis.

In the management of insomnia, physicians and patients are seeking alternative therapeutics to sleeping pills, in addition to sleep hygiene and cognitive behavioural therapy. Bright light therapy (LT) has proven its efficacy in circadian and mood disorders. We conducted a systematic literature review and meta-analysis according to Cochrane and PRISMA guidelines and using the databases Medline, Cochrane, and Web of Science, with a special focus on light therapy and insomnia.

Sleep Immune Cross Talk and Insomnia.

Sleep and immunity have bidirectional relationships. In this chapter, we review the links between sleep and immunity, focusing on immune changes occurring in the insomnia disorder. During physiological sleep, there is a decrease of pro-inflammatory cytokines (IL-1, IL-6 and TNF-α) and a decrease of anti-inflammatory cytokines (IL-4, IL-10).

Systematic Item Content and Overlap Analysis of Self-Reported Multiple Sleep Disorder Screening Questionnaires in Adults.

Sleep disorders are defined on the basis of diagnostic criteria presented in medical classifications. However, no consensus has emerged on the exact list of operational symptoms that should be systematically investigated in the field of sleep medicine. We propose a systematic analysis of sleep symptoms that figure in a set of self-reported multiple sleep disorder screening questionnaires for adult populations, to identify the content overlap of symptoms that probe the presence of central sleep symptoms, and to highlight the potential level of heterogeneity among sleep disorder questionnaires.

[How oxytocin became overtime the attachment-mediating hormone].

Oxytocin is a pleiotropic molecule which, in addition to its facilitating action during parturition and milk ejection, is involved in social and prosocial behaviors such as attachment. This article presents, after a brief historical review, the action of oxytocin during the milk ejection reflex. Oxytocin is indeed essential for this vital function in mammals.

Effect of lockdown on sleep-wake rhythm and alcohol use.

The global covid-19 pandemic has imposed radical changes in daily lives. This study reflects upon sociodemographic and clinical characteristics (sleep-wake rhythm, psychiatric symptoms, and alcohol use behavior) during the full lockdown, comparing individuals who increased their alcohol use (iAU), those who maintained a stable use (sAU), and those who did not consume alcohol (AnoU). Participants were recruited via e-mails and they were required to complete an online survey that included questionnaires, during the last week of the full lockdown.

Sleep Complaints Among Adults With Major Depressive Episode Are Associated With Increased Risk of Incident Psychiatric Disorders: Results From a Population-Based 3-Year Prospective Study.

Sleep alterations have been suggested as a cause and consequence of psychiatric disorders. In this context, we evaluated the incidence of psychiatric disorders following sleep complaints in adults with major depressive episode (MDE). In a large, nationally representative 3-year prospective survey, the National Epidemiologic Survey on Alcohol and Related Conditions conducted in 2001-2002 (Wave 1) and 2004-2005 (Wave 2), we used structural equation modeling to examine shared and specific effects of trouble falling asleep, early morning awakening, and hypersomnia on incidence of common comorbid disorders among patients with MDE.

A comparison of four methods to estimate dim light melatonin onset: a repeatability and agreement study.

Dim light melatonin onset (DLMO) is considered the most reliable circadian phase marker in humans. However, the methods to calculate it are diverse, which limits the comparability between studies. Given the key role of DLMO to diagnose circadian rhythm sleep-wake disorders and determine the optimal timing of chronotherapies, the establishment of clear and validated guidelines on the methodology to assess DLMO is very important.

Association between the experience of sexual violence and insomnia in a national sample of French adults.

Purposel: The experience of sexual violence has been associated with sleeping disorders; however, few studies have examined this association using a large sample of the general population. This study investigates whether lifetime experience of sexual violence and childhood experience of sexual violence are associated with insomnia.

Methods: Our study is based on data from the 2017 French Health Barometer, a general population phone cross-sectional survey, which included 25 319 adults aged 18-75 years in 2017.

Early skin-to-skin contact and risk of late-onset-sepsis in very and extremely preterm infants.

Background: To evaluate the association between exposure to early skin-to-skin contact (SSC) and incidence of late-onset sepsis (LOS) in extremely and very preterm infants.

Methods: Observational study using the national population-based EPIPAGE-2 cohort in 2011. A propensity score for SSC exposure was used to match infants with and without exposure to SSC before day 4 of life and binomial log regression used to estimate risk ratios and CIs in the matched cohort.

The Intertwining of Posttraumatic Stress Symptoms, Alcohol, Tobacco or Nicotine Use, and the COVID-19 Pandemic: A Systematic Review.

Background: Posttraumatic stress symptoms (PTSSs) and alcohol, tobacco, or nicotine use are frequently associated conditions. The COVID-19 pandemic has been a stressful situation globally and has worsened mental health conditions and addictions in the population. Our systematic review explores the links between PTSSs and (1) alcohol use and (2) tobacco or nicotine use during the COVID-19 pandemic.

Validation of a data collection set for the psychiatric, addiction, sleep and chronobiological assessments of patients with depression: A Delphi study for the SoPsy-depression French national cohort.

Objectives: Despite international efforts to identify biomarkers of depression, none has been transferred to clinical practice, neither for diagnosis, evolution, nor therapeutic response. This led us to build a French national cohort (through the clinical and research network named SoPsy within the French biological psychiatry society (AFPBN) and sleep society (SFRMS)), to better identify markers of sleep and biological rhythms and validate more homogeneous subgroups of patients, but also to specify the manifestations and pathogeneses of depressive disorders. Before inclusions, we sought to provide a predefined, standardized, and robust set of data to be collected in all centers.
