AI Article Synopsis
- Metabolic syndrome affects over a third of adults and increases the risk of diabetes, heart disease, and mortality, with muscle insulin resistance being a key factor in its development.
- Research in mice suggests that the phospholipid composition of skeletal muscle sarcoplasmic reticulum (SR) impacts insulin sensitivity.
- A study comparing skeletal muscle SR from sedentary individuals with and without metabolic syndrome revealed lower levels of specific phosphatidylcholine (PC) and phosphatidylethanolamine (PE) in those with metabolic syndrome, especially in females, linking decreased SR PC content to higher insulin resistance.
Article Abstract
Metabolic syndrome affects more than one in three adults and is associated with increased risk of diabetes, cardiovascular disease, and all-cause mortality. Muscle insulin resistance is a major contributor to the development of the metabolic syndrome. Studies in mice have linked skeletal muscle sarcoplasmic reticulum (SR) phospholipid composition to sarcoplasmic/endoplasmic reticulum Ca-ATPase activity and insulin sensitivity. To determine if the presence of metabolic syndrome alters specific phosphatidylcholine (PC) and phosphatidylethanolamine (PE) species in human SR, we compared SR phospholipid composition in skeletal muscle from sedentary subjects with metabolic syndrome and sedentary control subjects without metabolic syndrome. Both total PC and total PE were significantly decreased in skeletal muscle SR of sedentary metabolic syndrome patients compared with sedentary controls, particularly in female participants, but there was no difference in the PC:PE ratio between groups. Total SR PC levels, but not total SR PE levels or PC:PE ratio, were significantly negatively correlated with BMI, waist circumference, total fat, visceral adipose tissue, triglycerides, fasting insulin, and homeostatic model assessment for insulin resistance. These findings are consistent with the existence of a relationship between skeletal muscle SR PC content and insulin resistance in humans.

Modern treatment, a healthy diet, and physical activity routines lower the risk factors for metabolic syndrome; however, this condition is associated with all-cause and cardiovascular mortality worldwide. This investigation involved a randomized controlled trial, double-blind, parallel study. Fifty-eight participants with risk factors of metabolic syndrome according to the inclusion criteria were randomized into two groups and given probiotics (Lacticaseibacillus paracasei MSMC39-1 and Bifidobacterium animalis TA-1) (n = 31) or a placebo (n = 27).

To assess whether metabolic syndrome can be used as a reference index to evaluate the efficacy of neoadjuvant chemotherapy treatment for breast cancer (BC). Seventy cases of female BC patients who received neoadjuvant chemotherapy treatment and surgical treatment at the Glandular Surgery Department of Hebei Provincial People's Hospital from January 2021 to December 2023 were retrospectively collected, and clinical data such as puncture pathology were recorded. The clinical data were analyzed by 1-way analysis using the χ2 test, and further multifactorial logistic regression analysis was performed for statistically significant differences.

Background: Hearing impairment is a prevalent clinical feature in Morquio syndrome (mucopolysaccharidosis IVA or MPS IVA) patients, often presenting in diverse forms: conductive, sensorineural, or a combination known as mixed hearing loss. The mixed form entails a blend of both conductive and sensorineural elements, typically exhibiting a progressive trajectory. This scoping review aimed to comprehensively analyze available evidence pertaining to the pathophysiology, classification, epidemiology, and clinical management of hearing loss in individuals with MPS IVA.

Bisphenol A (BPA) is an "environmental obesogen" and this study aims to investigate the intergenerational impacts of BPA-induced metabolic syndrome (MetS), specifically focusing on unraveling mechanisms. Exposure to BPA induces metabolic disorders in the paternal mice, which are then transmitted to offspring, leading to late-onset MetS. Mechanistically, BPA upregulates Srebf1, which in turn promotes the Pparg-dependent transcription of Dicer1 in spermatocytes, increasing the levels of multiple sperm microRNAs (miRNAs).

Background: While several studies have suggested a connection between Metabolic Syndrome (MetS) and Hidradenitis Suppurativa (HS), a definitive analysis confirming the association between lipid abnormalities and HS based on actual lipid values is lacking. Previous research, using odds ratios from ICD codes, indicates links between elevated triglycerides and low high-density lipoprotein levels with HS. However, these findings may not fully represent real-life situations, as no comprehensive analysis using actual lipid measurements has been performed.
