Skeletal muscle is regarded as an endocrine and paracrine organ. Muscle-derived secretory proteins, referred to as myokines, mediate interactions between skeletal muscle mass and other organs such as the liver, adipose tissue, pancreas, bone, and the cardiovascular system. As individuals age, reduced levels of physical activity and sarcopenia (loss of skeletal muscle mass and strength) are associated with physical frailty and disability. Recently, several studies have suggested that the loss of

Background: As the use of continuous glucose monitoring (CGM) has increased, time in range (TIR) and other core CGM metrics are now emerging as the core metrics for clinical targets and assessing diabetic complications, beyond HbA1c. This study investigated the association between the CGM-derived TIR, hyperglycemia, hypoglycemia metrics, and albuminuria. Methods: A total of 866 subjects with type 2 diabetes who underwent 3 or 6 days of CGM and had urinary albumin-to-creatinine ratio (ACR) measur

An increase in relative skeletal muscle mass over time has a potential preventive effect on developing metabolic syndrome, independently of baseline skeletal muscle mass and glycometabolic parameters.

Relationship on new statin use and the risk of hepatocellular carcinoma (HCC) in patients with incident type 2 diabetes mellitus (T2DM), who might be at the risk of developing HCC, is uncertained. A nationwide population-based nested case-control study was conducted within the National Health Insurance Service National Sample Cohort 2002-2013 in Korea. Newly prescribed statin after newly diagnosed T2DM was defined as statin use. Controls were matched to case patients on age, sex, follow-up time,

BACKGROUND: Heart failure with preserved ejection fraction is an emerging global health issue attributed to an ageing population. However, the association between low skeletal muscle mass, sarcopenic obesity, and left ventricular diastolic dysfunction remains unclear. In the current study, we aimed to investigate the relationship between low skeletal muscle mass, sarcopenic obesity, and diastolic dysfunction in a large cohort of Korean adults. METHODS: We conducted a cross-sectional study of 31

Our findings indicate visceral adiposity is strongly associated with the alteration of myocardial glucose uptake evaluated by (18)FDG-PET, and its association further relates to T2DM.

The presence of significant liver fibrosis assessed via TE was independently associated with low BMD in NAFLD subjects.

Pneumonia is an inflammatory disease of thelung, responsible for high morbidity and mortality worldwide. It is caused by bacteria, viruses, fungi, or othermicroorganisms. Streptococcus pneumoniae, a gram-positivebacterium with over 90 serotypes, is the most commoncausative agent. Moreover, comorbid factors includingheart failure, renal disease, and pulmonary disease couldincrease the risk of pneumococcal pneumonia. Since theadvent of the pneumococcal vaccine in the 1980s, theincidence of pneumon

Statins, or 3-hydroxy-3-methylglutaryl coenzyme A (HMG-CoA) reductase inhibitors, are widely used to treat hypercholesterolemia for primary and secondary prevention of cardiovascular disease. Statins inhibit HMG-CoA reductase, the rate-limiting step in cholesterol synthesis, and modulate the downstream signaling of the mevalonate pathway. In addition to the primary effect, the antitumor effect of statins can be associated with mevalonate pathway-mediated and nonmevalonate pathway-mediated mechan

BACKGRUOUND: Given the association between nonalcoholic fatty liver disease and metabolic risks, a new term, metabolic dysfunction- associated steatotic liver disease (MASLD) has been proposed. We aimed to explore the association between MASLD and all-cause, cause-specific mortalities. METHODS: We included individuals with steatotic liver disease (SLD) from the Korean National Health Insurance Service. Moreover, SLD was defined as a fatty liver index ≥30. Furthermore, MASLD, metabolic alcohol-as

People can be easily exposed to manganese (Mn), the twelfth most abundant element, through various exposure routes. However, overexposure to Mn causes manganism, a motor syndrome similar to Parkinson disease, via interference of the several neurotransmitter systems, particularly the dopaminergic system in areas. At cellular levels, Mn preferentially accumulates in mitochondria and increases the generation of reactive oxygen species, which changes expression and activity of manganoproteins. Many
