Sleep medicine catalogue of knowledge and skills – Revision

The 'catalogue of knowledge and skills' for sleep medicine presents the blueprint for a curriculum, a textbook, and an examination on sleep medicine. The first catalogue of knowledge and skills was presented by the European Sleep Research Society in 2014. It was developed following a formal Delphi procedure. A revised version was needed in order to incorporate changes that have occurred in the meantime in the International Classification of Sleep Disorders, updates in the manual for scoring sleep and associated events, and, most important, new knowledge in sleep physiology and pathophysiology. In addition, another major change can be observed in sleep medicine: a paradigm shift in sleep medicine has taken place. Sleep medicine is no longer a small interdisciplinary field in medicine. Sleep medicine has increased in terms of recognition and importance in medical care. Consequently, major medical fields (e.g. pneumology, cardiology, neurology, psychiatry, otorhinolaryngology, paediatrics) recognise that sleep disorders become a necessity for education and for diagnostic assessment in their discipline. This paradigm change is considered in the catalogue of knowledge and skills revision by the addition of new chapters

Sleep disturbances in early clinical stages of psychotic and bipolar disorders: A meta-analysis

International audienceObjective: To provide a qualitative view and quantitative measure of sleep disturbances across and between early stages – clinical ultra high-risk and first episode – of psychotic and bipolar disorders. Methods: Electronic databases (PubMed, Cochrane, Embase, PsychINFO) were searched up to March 2021 for studies comparing sleep measures between individuals with an early stage and controls. Standard mean deviations (Cohen’s d effect sizes) were calculated for all comparisons and pooled with random-effects models. Chi-square tests were used for direct between-subgroups (ultra high-risk vs first episode) comparisons of standard mean deviations. The effects of age, sex ratio, symptoms and treatment were examined in meta-regression analyses. Results: A database search identified 13 studies that contrasted sleep measures between individuals with an early stage ( N = 537) and controls ( N = 360). We observed poorer subjective sleep quality (standard mean deviation = 1.32; 95% confidence interval, [1.01, 1.62]), shorter total sleep time (standard mean deviation =−0.44; 95% confidence interval, [−0.67, −0.21]), lower sleep efficiency (standard mean deviation = −0.72; 95% confidence interval, [−1.08, −0.36]), longer sleep onset latency (standard mean deviation = 0.75; 95% confidence interval, [0.45, 1.06]) and longer duration of wake after sleep onset (standard mean deviation = 0.49; 95% confidence interval, [0.21, 0.77]) were observed in early stages compared to controls. No significant differences were observed for any of the reported electroencephalographic parameters of sleep architecture. No significant between-subgroups differences were observed. Meta-regressions revealed a significant effect of the age and the antipsychotic status on subjective measures of sleep. Conclusion: The early stage population presents with significant impairments of subjective sleep quality continuity, duration and initiation. Systematic assessments of sleep in early intervention settings may allow early identification and treatment of sleep disturbances in this population

ASSOCIATION BETWEEN OBSTRUCTIVE SLEEP APNEA SYMPTOMS AND INCIDENCE OF DE NOVO HYPERTENSION IN A LARGE FRENCH POPULATION-BASED EPIDEMIOLOGICAL COHORT

International audienceObjective: There is a strong association between Obstructive Sleep Apnea (OSA) and hypertension but the effects of OSA symptoms on the risk of incident hypertension in previously normotensive individuals are not well documented. The aim of this prospective cohort study was to examine whether OSA symptoms (snoring and sleepiness) are associated with the incidence of hypertension independently of confounding factors including body mass index. Design and method: Data from the French population-based CONSTANCES cohort were analyzed. Participants, aged 18 to 69 years, were included between 2012 and 2016, and screened for OSA in 2017 using the Berlin Questionnaire. Snoring and sleepiness were assessed from the questionnaire, and considered as severe when they were declared to occur at least three times a week. Individuals who had a history of treated OSA, cardiovascular diseases or hypertension (defined either by blood pressure of 140/90 mmHg or more at the inclusion visit, or by self-reported hypertension or antihypertensive drugs delivering until 2017) were excluded from these analyses. We used Cox models, adjusted for age, gender, smoking, alcohol consumption, physical activity, education level, household income and body mass index, to compute hazards ratios (HR) of incident treated hypertension (defined by antihypertensive drugs delivering through linkage to the National Health Data System (SNDS)) until December 2020. Results: Among 36,798 normotensive subjects, the prevalence of high risk of OSA according to Berlin questionnaire was 7.6% and the incidence of treated hypertension was 4.2%. Risk of de novo treated hypertension increased significantly in participants who declared symptoms of severe snoring (adjusted HR [95% CI] = 1.17 [1.04-1.31]), severe sleepiness after sleep (adjusted HR [95% CI] = 1.18 [1.03-1.36]) and severe sleepiness during waking time (adjusted HR [95% CI] = 1.40 [1.23-1.64]), and increased with the weekly frequency of these symptoms with a dose-dependent relationship (p for trend <0.005). Conclusions: Self-declared snoring and sleepiness are associated with an increased risk of developing de novo hypertension. Our results suggest that primary care patients should be routinely screened for these symptoms, not only to identify possible OSA, but also to encourage preventive measures and regular blood pressure monitoring
