Article Abstract
We sought to investigate the influence of sarcopenia as defined by muscle strength and skeletal muscle mass (SMM) on sleep disturbance as evaluated by the Japanese version of Pittsburgh Sleep Quality Index (PSQI-J) in chronic liver diseases (CLDs) ( = 419). Muscle strength and muscle mass were determined by grip strength (GS) and SMM using bioimpedance analysis. Patients were classified into four types: type A ( = 61); decreased GS and decreased SMM; type B ( = 45); decreased GS and non-decreased SMM; type C ( = 102); non-decreased GS and decreased SMM; and type D ( = 211); non-decreased GS and non-decreased SMM. Factors associated with PSQI-J score 6 or more were examined. PSQI-J score 0⁻5 (normal) was found in 253 (60.4%); 6⁻8 (mild) in 97 (23.2%); 9⁻11 (moderate) in 45 (10.7%) and 12 or more (severe) in 24 (5.7%). Univariate analysis identified three factors to be significantly associated with PSQI-J score 6 or more: presence of liver cirrhosis (LC) ( = 0.0132); our classification of type A; B; C and D ( < 0.0001) and serum albumin level ( = 0.0041). Multivariate analysis showed that type A ( = 0.0021) and type B ( = 0.0220) were significant independent factors. In conclusion, sarcopenia in CLDs appears to be closely associated with sleep disturbance mainly due to muscle strength decline.

Evolution of Motor and Nonmotor Characteristics in an Idiopathic/Isolated REM Sleep Behavior Disorder Cohort.

Montreal Neurological Institute-Hospital, McGill University, Montreal, Canada.
Background And Objectives: Years before diagnosis of Parkinson disease (PD), dementia with Lewy bodies (DLB), or multiple system atrophy (MSA), mild prodromal manifestations can be detected. Longitudinal follow-up of people with prodromal synucleinopathy, particularly idiopathic/isolated REM sleep behavior disorder (iRBD), enables in-depth clinical phenotyping of early disease, which could facilitate stratification for clinical trials, provide the definition of appropriate end points, or predict phenoconversion more precisely. The aim of this study was to update and expand on previous studies assessing clinical evolution from iRBD to clinically diagnosed disease, up to 14 years before diagnosis.

Importance: There is an unmet need for long-term, safe, effective, and hormone-free treatments for menopausal symptoms, including vasomotor symptoms (VMS) and sleep disturbances.
Objective: To evaluate the 52-week efficacy and safety of elinzanetant, a dual neurokinin-targeted therapy, for treating moderate to severe VMS associated with menopause.
Design, Setting, And Participants: OASIS-3 was a double-blind, placebo-controlled, randomized phase 3 clinical trial that was conducted at 83 sites in North America and Europe from August 27, 2021, to February 12, 2024, and included postmenopausal women aged 40 to 65 years who were seeking treatment for moderate to severe VMS (no requirement for a minimum number of VMS events per week).

Sleep paralysis, colloquially known as "ghost pressing" is a state of momentary bodily immobilization occurring either at the onset of sleep or upon awakening. It is characterized by atonia during rapid eye movement (REM) sleep that continues into wakefulness, causing patients to become temporarily unable to talk or move but possessing full consciousness and awareness of their surroundings. Sleep paralysis is listed in the International Classification of Sleep Disorders, 3rd Edition (ICSD-3) as a parasomnia occurring during REM sleep that be classified as either isolated or narcolepsy-associated.

Study Objectives: To examine whether there is a temporal association between sleep disturbance and multimorbidity.
Methods: We performed a cross-sectional and longitudinal observational analysis in people aged 40 years or more, recruited from the knee pain and related health in the community cohort study. The primary exposure was the Sleep Problems Index II score in tertiles measured at baseline.
Associations between a novel measure of sleep health and cognitive functioning in middle childhood: a crosssectional Environmental Influences on Child Health Outcomes cohort study.

Study Objectives: Research linking children's sleep to cognitive outcomes is inconsistent and has largely focused on one aspect of sleep, such as duration, rather than measuring multiple dimensions of sleep health. We hypothesized that children's sleep health would be positively associated with inhibitory control and cognitive functioning.
Method: We cross-sectionally assessed 1595 participants (ages 7-11) from the Environmental influences on Child Health Outcomes cohort using the NIH Toolbox Cognition Battery, Environmental influences on Child Health Outcomes Sleep Health of Children and Adolescents questionnaire, and Patient Reported Outcome Measurement Information System Sleep Disturbance/Sleep-related Impairment instruments.
