Low muscle strength is an important heritable indicator of poor health linked to morbidity and mortality in older people. In a genome-wide association study meta-analysis of 256,523 Europeans aged 60 years and over from 22 cohorts we identify 15 loci associated with muscle weakness (European Working Group on Sarcopenia in Older People definition: n = 48,596 cases, 18.9% of total), including 12 loci not implicated in previous analyses of continuous measures of grip strength. Loci include genes reportedly involved in autoimmune disease (HLA-DQA1 p = 4 × 10), arthritis (GDF5 p = 4 × 10), cell cycle control and cancer protection, regulation of transcription, and others involved in the development and maintenance of the musculoskeletal system. Using Mendelian randomization we report possible overlapping causal pathways, including diabetes susceptibility, haematological parameters, and the immune system. We conclude that muscle weakness in older adults has distinct mechanisms from continuous strength, including several pathways considered to be hallmarks of ageing.

Postoperative fatigue (POF) and perioperatively acquired muscle weakness (POAW) are significant yet often under-recognised interlinked postoperative complications that can significantly hinder postoperative recovery and diminish overall quality of life after surgery. Despite advancements in surgical and anaesthetic techniques and the widespread implementation of Enhanced Recovery After Surgery (ERAS) protocols, these conditions remain prevalent. In the weeks following surgery, reported incidences of fatigue of any severity range from 10% to as high as 90%, depending on the patient population.

Introduction: Glycogen storage disease type IX (GSD type IX) is caused by a deficiency in phosphorylase b kinase (PHK) and is classified into hepatic (IXa-c) and muscular (IXd) subtypes. GSD type IXd leads to exercise intolerance, rhabdomyolysis, and myoglobinuria owing to impaired glycogen breakdown. It is a rare and mild metabolic disorder, with only 19 reported cases of mutations.

Cerebral infarction is a rare but serious complication after pulmonary resection for lung cancer. A 78-year-old man with hypertension and diabetes underwent video-assisted thoracoscopic right middle lobectomy for stage IA2 adenocarcinoma. On postoperative day 1, he developed acute right hemiparesis and motor aphasia.

For lumbar spinal canal stenosis, endoscopic spine surgery typically employs a unilateral approach. While this approach has the advantage of early access to the lamina, it risks damage to the facet joint on the entry side. Additionally, decompression of the ipsilateral lateral recess can be challenging, sometimes resulting in inadequate decompression laterally, leading to incomplete symptom relief.

Rationale: This study reports a rare case of both AA amyloidosis and elderly-onset Still disease presenting as fever following carpal tunnel syndrome surgery.
Patient Concerns: A 79-year-old man reported numbness, pain, and muscle weakness in his right hand for several months.
Diagnoses: We performed carpal tunnel opening surgery and a synovial biopsy because of significant synovial tissue in the carpal tunnel.
