Current Diabetes Reports最新文献

Purpose of review: Type 2 diabetes is frequently accompanied by obesity, nonalcoholic fatty liver disease, chronic kidney disease, and cardiovascular disease, which collectively contribute to the high burden of cardiometabolic disease. This review discusses cardiometabolic disease management, strategies to implement cardiometabolic centers to deliver care, and dedicated programs to train the next generation of cardiometabolic experts.

Recent findings: Sodium-glucose cotransporter 2 inhibitors, glucagon-like peptide 1 receptor agonists, and a nonsteroidal mineralocorticoid receptor antagonist have demonstrated beneficial effects across cardiometabolic conditions. However, utilization of effective pharmacotherapies is low in clinical practice, in part due to clinical inertia and traditional sharp delineation in clinical responsibilities of specialists. Multidisciplinary clinics and population-health models can provide comprehensive care but require investment in physical and information technology infrastructure as well as in training and accreditation. Post-internal medicine residency cardiometabolic health training programs have been proposed. Implementing cardiometabolic centers in health systems involves reshaping current practices. Training programs focused on cardiometabolic health are needed to address the growing burden of disease and specific training needs in this ever-expanding area.

Purpose of review: Type 2 diabetes (T2D) is a multifactorial, heritable syndrome characterized by dysregulated glucose homeostasis that results from impaired insulin secretion and insulin resistance. Genetic association studies have successfully identified hundreds of T2D risk loci implicating many genes in disease pathogenesis. In this review, we provide an overview of the recent T2D genetic studies from the past 3 years with particular focus on the effects of sample size and ancestral diversity on genetic discovery as well as discuss recent work on the use and limitations of genetic risk scores (GRS) for T2D risk prediction.

Recent findings: Recent large-scale, multi-ancestry genetic studies of T2D have identified over 500 novel risk loci. The genetic variants (i.e., single nucleotide polymorphisms (SNPs)) marking these novel loci in general have smaller effect sizes than previously discovered loci. Inclusion of samples from diverse ancestral backgrounds shows a few ancestry specific loci marked by common variants, but overall, the majority of loci discovered are common across ancestries. Inclusion of common variant GRS, even with hundreds of loci, does not substantially increase T2D risk prediction over standard clinical risk factors such as age and family history. Common variant association studies of T2D have now identified over 700 T2D risk loci, half of which have been discovered in the past 3 years. These recent studies demonstrate that inclusion of ancestrally diverse samples can enhance locus discovery and improve accuracy of GRS for T2D risk prediction. GRS based on common variants, however, only minimally enhances risk prediction over standard clinical risk factors.

Purpose of review: This review focuses on new clinical data involving a novel class of drugs, nonsteroidal mineralocorticoid receptor antagonists (NS-MRAs), specifically, finerenone and its effects on cardiovascular and diabetic kidney disease outcomes.

Recent findings: NS-MRAs are a novel class of agents for treating diabetic kidney disease (DKD). While they are chemically and pharmacologically distinct from steroidal MRAs (spironolactone, eplerenone), they effectively inhibit the MR receptor differently. Inhibition of MR receptor activation reduces inflammatory and profibrotic pathways involving the cardiorenal/vascular systems. Small diabetic kidney disease (DKD) clinical studies demonstrate that steroidal MRAs reduce albuminuria relative to placebo, although hyperkalemia is a major adverse event that has precluded large outcome trials. The NS-MRA, finerenone, demonstrated slowed progression of DKD and reduction of cardiovascular death primarily driven by reduced heart failure incidence in two separate randomized controlled clinical trials (FIDELIO and FIGARO). Use of NS-MRAs, therefore, provides a third "pillar of therapy" to reduce cardiorenal events added to blockers of the renin-angiotensin system and SGLT2 inhibitors. If the pending outcome trial, FLOW, is positive, potentially, GLP1-RAs may also be part of this "pillar" structure.

Purpose of review: To introduce behavioral economics (BE), provide a description of how recent prevention and treatment interventions in persons with diabetes have incorporated BE in their intervention strategies, and discuss how BE could be used to inform new treatments for the clinical setting or research.

Recent findings: In most of the trials described, researchers incorporated BE into their design in the form of incentives, which can align with present bias, optimism bias, and loss aversion. With only two exceptions, these trials reported preliminary support for using incentives to promote lifestyle modifications and diabetes-related tasks. Additionally, two trials reported promising results for behavior change strategies informed by default bias, while three trials reported promising results for behavior change strategies informed by social norms. Recent trials incorporating BE in prevention and treatment interventions for persons with diabetes generally report promising results, though gaps exist for research and clinical deployment.
