Background: Few studies have examined the effect of insulin resistance on the association between alanine aminotransferase (ALT) and metabolic syndrome. The association between ALT levels and metabolic syndrome were determined, independently of insulin resistance in Korean populations.
Methods And Results: The association between ALT and metabolic syndrome were examined in 28,456 subjects who visited 7 Health Promotion Centers at University Hospitals in Korea from 2006 to 2008. HOMA-IR index was used to represent insulin resistance index. ALT levels were found to be positively associated with metabolic syndrome after adjusting for age, alcohol intake, and smoking status. Furthermore, when additional adjustment was made for insulin resistance, this association between ALT and metabolic syndrome, although slightly attenuated, remained strongly significant. Subjects in the highest ALT quartile were found to have a higher risk of having metabolic syndrome than those in the lowest quartile (odds ratio (OR)=4.45, 95% confidence interval (CI)=3.96-4.99 for men and OR=3.51, 95%CI=2.73-4.52 for women). In addition, the association between ALT level and the risk of metabolic syndrome was significantly higher in the relatively low risk group.
Conclusions: ALT levels were found to be significantly associated with metabolic syndrome independently of insulin resistance and with an interaction by age. Further cohort studies are needed to determine the usefulness of ALT levels for predicting the risk of metabolic syndrome.

Innovative and easy-to-implement strategies are needed to improve the pathogenicity assessment of rare germline missense variants. Somatic cancer driver mutations identified through large-scale tumor sequencing studies often impact genes that are also associated with rare Mendelian disorders. The use of cancer mutation data to aid in the interpretation of germline missense variants, regardless of whether the gene is associated with a hereditary cancer predisposition syndrome or a non-cancer-related developmental disorder, has not been systematically assessed.

Menopause is a complex period in women's life, when weight gain and predisposition to obesity are frequent. Moreover, even during menopause transition, women begin to lose lean mass up to 0.5% and, therefore, an increase in the percentage of fat mass with central distribution and an increased risk of metabolic syndrome.

Bullous pemphigoid (BP) is a chronic autoimmune subepidermal blistering disease, affecting mostly the elderly. Metabolic syndrome (MetS) is a set of metabolic disorders including obesity, hypertension, glucose intolerance, and dyslipidemia. Observational studies have revealed a correlation between BP and MetS with controversial results and the causal relationship needs to be clarified.

The discovery of the functioning of intra- and extracellular ion compartments and cell membranes' operation opened the possibility of extending Claude Bernard's theory to intracellular ions. In contrast, by underestimating the role of ions, many misconceptions have prevailed. The author points out that maintaining the constancy of carbon dioxide is especially important.

Polycystic Ovary Syndrome (PCOS) is the most common endocrine-metabolic disorder in female adolescents, and it is associated with metabolic, cardiovascular, and reproductive complications. Recent findings also suggest an association with psychiatric pathology, both affected patients and their offspring. In this update, we synthesized the recent literature on mental health in women and adolescents with PCOS through a systematic search in PubMed, Epistemonikos, and Scielo for articles published in the last 5 years.
