Context: Adiponectin is a hormone secreted by adipocytes that acts as an antidiabetic adipokine. Adiponectin exists as multimers in plasma, and high molecular weight (HMW) adiponectin is particularly thought to be the active form of the protein.
Objective: The aim of the study was to assess whether decreased total and HMW adiponectin are independent risk factors for the development of type 2 diabetes.
Design: Study subjects were Japanese-Americans enrolled in the Hawaii-Los Angeles-Hiroshima study between 1992 and 2002. Duration of follow-up was an average of 5.4 yr.
Participants: We investigated 321 men and 445 women who were nondiabetic Japanese-Americans. Glucose tolerance was evaluated according to 1997 American Diabetes Association criteria, and 112 subjects developed type 2 diabetes during the follow-up period.
Main Outcome Measure: The influence of baseline total and HMW adiponectin on the development of type 2 diabetes was the main outcome measure.
Results: Subjects who developed type 2 diabetes had significantly decreased plasma total and HMW adiponectin compared with those who did not develop the disease (P < 0.001, respectively). In a Cox proportional hazards model, both decreased total and HMW adiponectin levels were independent risk factors for the progression to type 2 diabetes after adjusting for sex, age, body mass index, waist-to-hip ratio, homeostasis model assessment, and classification of 75-g glucose tolerance test (hazards ratio: total, 0.600, P = 0.018; HMW, 0.614, P = 0.001, respectively). Dividing tertiles of adiponectin, hazards ratios in the lowest vs. highest tertile were total, 1.787 (95% confidence interval, 1.006-3.173); and HMW, 2.493 (95% confidence interval, 1.342-4.632), after similar adjustments.
Conclusions: Decreased total adiponectin is an independent risk factor for the progression to type 2 diabetes in Japanese-Americans. Moreover, HMW adiponectin more closely associates with the progression to type 2 diabetes when compared with total adiponectin.

Aerobic exercise (AE) is associated with a significant hypoglycemia risk in individuals with type 1 diabetes mellitus (T1DM). However, the mechanisms in the liver and skeletal muscle governing exercise-induced hypoglycemia in T1DM are poorly understood. This study examined the effects of a 60-minute bout of AE on hepatic and muscle glucose metabolism in T1DM rats.

The global epidemiology of HCC is shifting due to changes in both established and emerging risk factors. This transformation is marked by an emerging prevalence of metabolic dysfunction-associated steatotic liver disease (MASLD) and type 2 diabetes, alongside traditional risks such as viral hepatitis (HBV and HCV), and exposure to chemical agents like aflatoxin, alcohol, tobacco, and air pollution. This review examines how environmental exposures and evolving liver pathology, exacerbated by lifestyle and metabolic conditions, are contributing to the rising worldwide incidence of HCC.

Objectives: to understand the perspective of nurses on the use of telemonitoring in the management of people with type 2 diabetes mellitus and arterial hypertension in primary care.
Methods: this qualitative research involved sixteen nurses from eight municipalities in Paraná. Data were collected between November 2022 and January 2023 through inperson or remote interviews, which were audio-recorded and subjected to content analysis.

Objective: Calorie restriction and exercise are commonly used first interventions to prevent the progression of prediabetes and alleviate the symptoms of type 2 diabetes. Our study was designed to determine the effect of the energy deficit caused by long-term (12-week) calorie restriction and exercise programs on appetite responses in obese individuals with prediabetes and type 2 diabetes.
Methods: Calorie restriction and exercise programs appropriate for age, gender, and work environment were applied to 22 individuals with prediabetes and 22 with type 2 diabetes participating in the study for a period of 12 weeks.

Background: Rural populations in the United States face a diabetes mortality penalty. Self-management is a core component of treatment for type 2 diabetes, but there is low uptake of self-management education and support interventions in rural areas. Rural structural barriers to diabetes self-management have been described, yet the role of rural culture has not been extensively explored.
