Marti, ‘massima convergenza’ in Commissione Istruzione al Senato

Objectives
There are limited data on the relationship between sleep duration and possible sarcopenia. Hence, this study aimed to investigate the associations of sleep duration with possible sarcopenia and its defining components based on the China Health and Retirement Longitudinal Study (CHARLS).

Design
A retrospective cohort study.

Setting
This study was conducted on participants aged over 45 years applying the 2011 baseline and 2015 follow-up survey from CHARLS covering 450 villages, 150 counties and 28 provinces.

Participants
Data from 5036 individuals (2568 men and 2468 women) free of possible sarcopenia at baseline were analysed.

Primary and secondary outcome measures
The dose-response relationship between sleep duration and possible sarcopenia.

Results
During 4 years of follow-up, 964 (19.14%) participants developed possible sarcopenia. Compared with participants who slept 6–8 hours per night, those with shorter sleep duration (8 hours per night) was not significantly associated with incident possible sarcopenia. The plots of restricted cubic splines exhibited an atypical inverse J-shaped association between sleep duration and possible sarcopenia. Subgroup analysis showed a stronger association between sleep duration and possible sarcopenia in participants aged 45–59 years and composed of male populations.

Conclusions
Short sleep duration was a potential risk factor for possible sarcopenia and low handgrip strength. The improvement of sleep duration should be considered a target in early preventive and administrative strategies against the development of handgrip strength decline and further reduced the occurrence of sarcopenia.

Serve un sistema che integri i dati che arrivano da varie fonti

Objective
This review aims to provide an estimate of sarcopenia prevalence and its impact on clinical characteristics in patients with systemic sclerosis (SSc).

Design
Systematic review and meta-analysis.

Data sources
Embase, Medline, Web of Science and the Cochrane Central Register of Controlled Trials were systemically searched from inception to 24 May 2023.

Eligibility criteria for selecting studies
We included observational studies that reported the prevalence of sarcopenia in patients with SSc.

Data extraction and synthesis
Two reviewers independently performed study selection and data extraction using standardised methods. Risk of bias was assessed using the Agency for Healthcare Research and Quality Scale and the Newcastle–Ottawa Scale. Meta-analysis was conducted using random effects models.

Results
A total of 4583 articles were screened and 9 studies with data from 815 patients were included in the analysis (8 cross-sectional studies and 1 retrospective cohort study). The overall prevalence of sarcopenia in patients with SSc was 22% (95% CI 17% to 28%). Patients with SSc with sarcopenia had a poorer quality of life (mean difference –12.02; 95% CI –19.11 to –4.93) and higher C reactive protein (CRP) levels (standardised mean difference 0.67; 95% CI 0.35 to 1.00).

Conclusions
Sarcopenia is common in patients with SSc. Patients with SSc with sarcopenia had a worse quality of life and higher CRP levels, based on our findings. Given the detrimental impact of sarcopenia on quality of life, future efforts aimed at early identification of sarcopenia in the clinical assessment of patients with SSc may have significance.

Introduction
Sarcopenia is the age-associated loss of muscle mass and strength. Nicotinamide adenine dinucleotide (NAD) plays a central role in both mitochondrial function and cellular ageing processes implicated in sarcopenia. NAD concentrations are low in older people with sarcopenia, and increasing skeletal muscle NAD concentrations may offer a novel therapy for this condition. Acipimox is a licensed lipid-lowering agent known to act as an NAD precursor. This open-label, uncontrolled, before-and-after proof-of-concept experimental medicine study will test whether daily supplementation with acipimox improves skeletal muscle NAD concentrations.

Methods and analysis
Sixteen participants aged 65 and over with probable sarcopenia will receive acipimox 250 mg and aspirin 75 mg orally daily for 4 weeks, with the frequency of acipimox administration being dependent on renal function. Muscle biopsy of the vastus lateralis and MRI scanning of the lower leg will be performed at baseline before starting acipimox and after 3 weeks of treatment. Adverse events will be recorded for the duration of the trial. The primary outcome, analysed in a per-protocol population, is the change in skeletal muscle NAD concentration between baseline and follow-up. Secondary outcomes include changes in phosphocreatine recovery rate by 31P magnetic resonance spectroscopy, changes in physical performance and daily activity (handgrip strength, 4 m walk and 7-day accelerometry), changes in skeletal muscle mitochondrial respiratory function, changes in skeletal muscle mitochondrial DNA copy number and changes in NAD concentrations in whole blood as a putative biomarker for future participant selection.

Ethics and dissemination
The trial is approved by the UK Medicines and Healthcare Products Regulatory Agency (EuDRACT 2021-000993-28) and UK Health Research Authority and Northeast – Tyne and Wear South Research Ethics Committee (IRAS 293565). Results will be made available to participants, their families, patients with sarcopenia, the public, regional and national clinical teams, and the international scientific community.

Morto a 92 anni per i postumi di un incidente a Forlì

Objectives
The association between sarcopenia severity and fall history remains under-researched at present. Accordingly, this study was developed to evaluate the relationship between sarcopenic status and prior fall events in a multiethnic group of older community-dwelling adults in Western China.

Design
A retrospective survey study, the data comes from the West China Health and Aging Trend study.

Setting
The study was based in Western China.

Participants
In total, this retrospective analysis incorporated data from 2719 older adults (59.2% women).

Primary and secondary outcome measures
Grip strength, gait speed and skeletal muscle mass index values were analysed for all participants, and the Asian Working Group for Sarcopenia (AWGS) 2014 and 2019 consensus criteria were leveraged to assess sarcopenia status in these individuals. Prior fall history was defined by any incidents in which an individual unintentionally came to rest on the floor within the past year. The association between sarcopenia status and fall history was examined through a binary logistic regression approach, with p
