Aims: Sarcopenia, one of the primary diseases of the older adult population, is a condition characterized by loss of skeletal muscle mass, strength and functionality. Due to its considerable economic impact, preventive interventions for sarcopenia play an important role in the older adult population. Urine includes many indicators of physiology and pathophysiology. Urine analysis is used to diagnose many different diseases. The goal of this cohort study was to examine the relationship between urine pH level and skeletal muscle mass.

Methods: This community-based cross-sectional study was carried out among 9712 Taiwanese individuals (4992 men and 4720 women). We used urine pH as an independent variable and skeletal muscle mass as a dependent variable. Bioelectric impedance analysis was used to measure the percentage of skeletal muscle mass (PSMM). We collected first fasting morning urine samples after overnight fasting, and urine pH was measured with a dipstick. In the by-sex and by-obesity analyses, we stratified the sample into two subgroups and a linear regression model was used for covariate adjustment.

Results: In the fully adjusted model, all-subject analysis showed a statistically significant association between urine pH and the PSMM with a β coefficient of 0.820 (95% CI 0.615-1.025; P < 0.001). Additionally, by-sex analysis showed that urine pH was related to the PSMM in both sexes, with β coefficients of 0.261 (95% CI 0.006-0.516; P = 0.045) in men and 0.179 (95% CI 0.029-0.328; P = 0.019) in women. By-obesity status analysis showed that urine pH was related to the PSMM in the body mass index <27 group with a β coefficient of 0.284 (95% CI 0.101-0.466; P = 0.002) after full adjustment. However, for the body mass index ≥27 group, there was no significant relationship between urine pH and the PSMM (P > 0.05).

Conclusion: The results showed the impacts of urine pH levels on skeletal muscle mass in both sexes and non-obese populations. Due to its easily accessible and economical characteristics, urine analysis is a convenient way to approach patients with low skeletal muscle mass and predict sarcopenia.

Purpose Muscle atrophy progresses with age. The motor function may be estimated by measuring the muscle mass; however, if muscle quality deteriorates due to an increase in connective tissue within the muscle, a decline in motor function may be missed by measuring muscle mass alone. Therefore, it is important to understand the relationship between muscle mass, muscle quality, and motor function.

An uncommon and recently identified Müllerian anomaly is the accessory cavitated uterine mass (ACUM). It is distinguished by the presence of a noncommunicating auxiliary cavity inside the uterus, located near and surrounded by uterine smooth muscle, and bordered by functioning endometrium beneath the round ligament's insertion, with a perfectly healthy uterus, ovaries, tubes, and cavity. Given that it is a congenital ailment with a persistent Müllerian duct at the level of the round ligament, primarily resulting from gubernaculum dysfunction, it usually manifests clinically as childhood dysmenorrhea in girls.

Background: This video article describes the use of bone-anchored prostheses for patients with transtibial amputations, most often resulting from trauma, infection, or dysvascular disease. Large studies have shown that about half of all patients with a socket-suspended artificial limb experience limited mobility and limited prosthesis use because of socket-related problems. These problems occur at the socket-residual limb interface as a result of a painful and unstable connection, leading to an asymmetrical gait and subsequent pelvic and back pain.

Prevalence of Sarcopenia in Connective Tissue Disease Associated Interstitial Lung Diseases: A Single-Centre Study from India.

Department of Pulmonary Medicine, Kalinga Institute of Medical Sciences, KIIT University, Bhubaneswar, Odisha, India.

Background: Sarcopenia, a progressive loss of skeletal muscle strength and mass, can lead to decreased quality of life, physical disability, and mortality. Early identification of sarcopenia is crucial in limiting morbidity and mortality in connective tissue disease associated interstitial lung diseases (CTDILD) patients.

Objective: The objectives of this study are to determine the prevalence of sarcopenia in CTD-ILD patients and to correlate the severity of sarcopenia with pulmonary function tests, spirometry, and 6-minute walk test (6MWT).

Cultured meat aims to produce meat mass by culturing cells and tissues based on the muscle regeneration mechanism, and is considered an alternative to raising and slaughtering livestock. Hydrogel building blocks are commonly used as substrates for cell culture in tissue engineering and cultured meat because of their high water content, biocompatibility, and similar three-dimensional (3D) environment to the cellular niche . With the characteristics of precise manipulation of fluids, microfluidics exhibits advantages in the fabrication of building blocks with different structures and components, which have been widely applied in tissue regeneration.
