Study Design: Cross-sectional study.
Objective: Describe and compare ambulatory performance and cognitive capacity in relation to muscle function in an adult cohort with spina bifida. Also, explore factors associated with ambulation in participants with muscle function level 3.
Setting: Specialist clinic for adults with spinal cord disorders in Stockholm, Sweden.
Methods: A total regional cohort of adults (n = 219) with spina bifida was invited, 196 (104 women, mean age 35 years, SD 13 years) participated. Mode of mobility, cognitive capacity and muscle function were investigated. For participants with muscle function level 3, factors associated with ambulation were investigated using multivariate logistic regression analysis.
Results: In all, 84 participants (42%) were community ambulators, 22 (12%) household ambulators and 90 (46%) wheelchair users. There was a linear association between the lower degree of muscle function and scoliosis (P < 0.001). Mode of mobility varied despite similar muscle prerequisites in participants with muscle function level 3 (n = 58). Factors associated with ambulation in participants with muscle function level 3 were the absence of scoliosis, lower BMI and higher cognitive capacity.
Conclusions: Cognitive capacity and mode of mobility varied widely across the cohort. However, in participants with muscle function level 3, despite similar muscular prerequisites, a large variation in the mode of mobility was found, suggesting that other factors were involved. It is important to prevent scoliosis, support a healthy lifestyle, as well as offer cognitive screening and support to promote ambulatory function and optimise independence in the everyday lives of adults with spina bifida.

Background: Crohn's disease and irritable bowel syndrome may both cause abdominal pain and diarrhea. Irritable bowel syndrome not only is an important differential diagnosis for Crohn's disease but also occurs in one out of three patients with Crohn's disease in remission in parallel. If not adequately diagnosed and treated, additional functional symptoms such as fatigue and/or muscle pain may develop, indicating a more severe course.

Background: Increased levels of inflammation in cancer patients and survivors can make them more prone to muscle wasting and sarcopenia. Diet can be an appropriate treatment for alleviating patient complications. Therefore, this study was performed to determine the association between sarcopenia and its components with the dietary inflammatory index (DII) among breast cancer survivors.

Background: Maintaining the connection between skeletal muscle fibers and the surrounding basement membrane is essential for muscle function. Dystroglycan (DG) serves as a basement membrane extracellular matrix (ECM) receptor in many cells, and is also expressed in the outward-facing membrane, or sarcolemma, of skeletal muscle fibers. DG is a transmembrane protein comprised of two subunits: alpha-DG (α-DG), which resides in the peripheral membrane, and beta-DG (β-DG), which spans the membrane to intracellular regions.

This review comprehensively explores the critical role of calcium as an essential small-molecule biomessenger in skeletal muscle function. Calcium is vital for both regulating muscle excitation-contraction coupling and for the development, maintenance, and regeneration of muscle cells. The orchestrated release of calcium from the endoplasmic reticulum (ER) is mediated by receptors such as the ryanodine receptor (RYR) and inositol 1,4,5-trisphosphate receptor (IP3R), which is crucial for skeletal muscle contraction.

Background: Sarcopenia is an age-related syndrome marked by a gradual decline in skeletal muscle mass and function. While various factors influencing sarcopenia have been studied, the link between daily sedentary time and sarcopenia remains underexplored.
Method: This study analyzed the association between daily sitting time and sarcopenia using data from the National Health and Nutrition Examination Survey (NHANES 2011-2018).
