Abstract Background Diabetic retinopathy (DR) is the leading cause of preventable blindness worldwide. Machine learning (ML) systems can enhance DR in community-based screening. However, predictive power models for usability and performance are still being determined. Objective This study used data from 3 university hospitals South Korea to conduct a simple accurate assessment ML-based risk prediction development that be universally applied adults with type 2 diabetes mellitus (T2DM)....

Prolactin is a hormone secreted from lactotroph cells in the anterior pituitary gland to induce lactation after birth. Hyperprolactinemia unrelated common cause of amenorrhea women childbearing age, and consequent decrease gonadotropin-releasing (GnRH) by high prolactin level can result decreased bone mineral density. Osteoporosis skeletal disorder characterized density (BMD) quality, which results strength. In patients with hyperprolactinemia, changes BMD be induced indirectly inhibition...

Sodium-glucose co-transporter 2 inhibitors, such as enavogliflozin, offer promising metabolic benefits for patients with type diabetes (T2D), including glycemic control and improved cardiac function. Despite the clinical evidence, real-world evidence is needed to validate their safety effectiveness. This study aims evaluate effects of weight loss enavogliflozin administration in T2D a setting over 24 weeks. large-scale, prospective, multicenter, non-interventional observational will be...

<title>Abstract</title> Background This study analyzed the prevalence of metabolic syndrome (MetS) among Korean adults aged 19 and older over past 15 years. Methods A cross-sectional data from Korea National Health Nutrition Examination Survey (KNHANES) 2007 to 2022 was conducted. The included 87,397 subjects. MetS defined according Cholesterol Education Program-Third Adult Treatment Panel (NCEP-ATP) III Society for Study Obesity (KOSSO) criteria. Results increased 22.8% in 28.6% but showed...

While endocrine disruptors are emerging as a cause of nonalcoholic fatty liver disease (NAFLD), little is known about the link between NAFLD and organochlorine pesticides (OCPs), one disruptors. We retrospectively analyzed U.S. National Health Nutrition Examination Survey 2003-2004 compared baseline demographics in individuals according to presence (fatty index [FLI] ≥ 60). Logistic regression analysis was performed determine whether OCP concentration affected prevalence subgroup analyses...

Background Several machine learning (ML) prediction models for neurodegenerative diseases (NDs) in type 2 diabetes mellitus (T2DM) have recently been developed. However, the predictive power of these is limited by lack multiple risk factors. Objective This study aimed to assess validity and use an ML model predicting 3-year incidence ND patients with T2DM. Methods We used data from independent cohorts—the discovery cohort (1 hospital; n=22,311) validation (2 hospitals; n=2915)—to predict ND....

Acute inhalation exposure to high levels of manganese (Mn) is associated with pulmonary edema and impaired function. The immune-mediated lung epithelium injury Mn in vivo vitro experiments has been well characterized, whereas its apoptotic effect not defined. Our results show that human bronchial epithelial (16HBE) cells undergo caspase-9-mediated cell death response Mn. Loss mitochondrial membrane potential (ΔΨm), the formation reactive oxygen species release cytochrome c were regulated...
