The accumulation of an excessive amount of body fat can cause type 2 diabetes, and the risk of type 2 diabetes increases linearly with an increase in body mass index. Accordingly, the worldwide increase in the prevalence of obesity has led to a concomitant increase in the prevalence of type 2 diabetes. The cellular and physiological mechanisms responsible for the link between obesity and type 2 diabetes are complex and involve adiposity-induced alterations in β cell function, adipose tissue biology, and multi-organ insulin resistance, which are often ameliorated and can even be normalized with adequate weight loss.

Background And Aim: There is paucity of data about the prevalence of cirrhosis and portal hypertension in the US general population.

Methods: We used National Health and Nutrition Examination Surveys (NHANES 2017-2020) to estimate the prevalence of cirrhosis and clinically significant (CS)-portal hypertension in alcoholic liver disease (ALD), MetALD, viral hepatitis (VH) to include chronic hepatitis B (CHB) and chronic hepatitis C (CHC), and metabolic dysfunction-associated steatotic liver disease (MASLD). Cirrhosis was evaluated using liver stiffness measurement (LSM) by transient elastography or FIB-4 score; CS-portal hypertension was defined via LSM and platelet count or the use of non-selective beta-blockers in the presence of cirrhosis.

Objective: to map the available evidence on the characteristics of care coordination between Primary Health Care and Specialized Outpatient Care for users with diabetes and hypertension.

Method: this is a scoping review with 40 articles as the final sample, evaluated by means of Content Analysis, of the thematic-categorical type, with the aid of a technological tool.

Results: care coordination was defined by means of eight categories: information and communication, integration of care, improvement and quality, care management, care sharing, fundamental attribute, health professionals and health service users, with the results of the articles concentrating mainly on four categories, with information and communication standing out, followed by the category of care management and the category of care sharing, in parallel with improvement and quality.

Objective: Type1Screen offers islet autoantibody testing to Australians with a family history of type 1 diabetes (T1D) with the dual aims of preventing diabetic ketoacidosis (DKA) and enabling use of disease-modifying therapy. We describe screening and monitoring outcomes 2 years after implementing in-home capillary blood spot sampling.

Research Design And Methods: Data from 2,064 participants who registered between July 2022 and June 2024 were analyzed: 1,507 and 557 chose blood spot and venipuncture screening respectively.
