Sarcopenia is characterized by loss of muscle mass during aging, which can have consequences for the individuals’ health. There are many ways to detect it, among them, with the use of blood biomarkers such as albumin, although the association between the two has not been confirmed yet. This review synthesizes the knowledge on the association between sarcopenia and serum albumin among elderly individuals through a systematic review and meta-analysis focused on the etiology and risk factors. We used the Joanna Briggs Institute software for the review and conducted a search in MEDLINE, Embase, CINAHL, and LILACS databases while two reviewers conducted an independent manual search. EpiDat, version 3.1 was used for the meta-analysis; mean differences with the albumin scores disaggregated by sarcopenia were analyzed by the random-effects model. The degree of heterogeneity was assessed with the DerSimonian and Laird Q test. We analyzed 630 articles and finally included 14 in the review. Higher blood albumin levels were found in the meta-analysis, which was statistically significant among the elderly adults who did not present sarcopenia compared to those who did. Although there are studies exploring the association between albumin and sarcopenia, there is a need to continue evaluating its association with biological markers and comparing them to verify which can be used to detect sarcopenia among the elderly.

Nephrology Department, Changzhou Traditional Chinese Medicine Hospital, Changzhou City, China.
To evaluate the effectiveness and feasibility of the copper bianstone scraping combined with Chinese modified termination hypertension dietary therapy program by comparing and analyzing the improvement of blood pressure, blood lipids and blood glucose in hypertensive patients who received copper bianstone scraping combined with Chinese modified termination hypertension dietary therapy intervention. We selected 160 cases of hypertensive patients from July 2022 to March 2024 for the study. They were divided into 80 cases in the comparison group and 80 cases in the observation group according to whether or not they underwent copper bianstone scraping combined with Chinese modified dietary therapy for termination of hypertension.

Previous studies have provided relatively limited evidence in examining the impact of preoperative serum albumin levels on the length of hospital stay (LOS) in patients with hip fractures. This study aimed to elucidate the association between preoperative serum albumin levels and LOS in elderly patients with hip fractures. This retrospective cohort study included 1444 elderly patients undergoing surgical treatment for hip fractures at the Second People's Hospital of Shenzhen from January 2012 to December 2021.

This study aimed to determine the association between chronic schizophrenia, extrapyramidal symptoms (EPSs), body composition, nutritional status, and dynapenia/sarcopenia. Data from 68 chronic patients with schizophrenia were analyzed using Spearman's rho correlation coefficients, Kruskal-Wallis test, Mann-Whitney U test, and Cramér's V statistics. Among the participants, 32.

Introduction: In chronic kidney disease (CKD) patients, elevated parathyroid hormone (PTH) is linked to cardiovascular mortality and morbidity. Levels of PTH are influenced by serum phosphate (P) and calcium (Ca), but little is known about the impact of magnesium (Mg) on PTH. Hence, this study investigated the relationship between PTH and Mg in peritoneal dialysis (PD) patients and non-dialysis patients from three hospitals in China.
