Objective: To test whether diabetic polyneuropathies (DPNs), retinopathy, or nephropathy is more prevalent in subjects with impaired glycemia (IG) (abnormality of impaired fasting glucose [IFG], impaired glucose tolerance [IGT], or impaired HbA(1c) [IA1C]) than in healthy subjects (non-IG).
Research Design And Methods: Matched IG and non-IG volunteers were randomly identified from population-based diagnostic and laboratory registries, restudied, and reclassified as non-IG (n = 150), IG (n = 174), or new diabetes (n = 218).
Results: Frequency (%) of DPN in non-IG, IG, and new diabetes was 3 (2.0%), 3 (1.7%), and 17 (7.8%) narrowly defined (no other cause for polyneuropathy) and 19 (12.7%), 22 (12.6%), and 38 (17.4%) broadly defined. Mean and frequency distribution of composite scores of nerve conduction and quantitative sensation tests were not significantly different between IG and non-IG but were worse in new diabetes. Frequency of retinopathy and nephropathy was significantly increased only in new diabetes. In secondary analysis, small but significant increases in retinopathy and nephropathy were found in IGT, IFG, and IGT combined groups.
Conclusions: In population studies of Olmsted County, Minnesota, inhabitants, prevalence of typical DPN, retinopathy, and nephropathy was significantly increased only in subjects with new diabetes-not in subjects with IG as defined by American Diabetes Association (ADA) criteria of abnormality of IFG, IGT, or IA1C. For atypical DPN, such an increase was not observed even in subjects with new diabetes. In medical practice, explanations other than IG should be sought for patients with atypical DPN (chronic idiopathic axonal polyneuropathy) who have IG.

Clonal haematopoiesis of indeterminate potential (CHIP) is associated with macrovascular diseases, including coronary artery disease and stroke. However, the effects of CHIP on microvascular complication have not been evaluated in individuals with type 2 diabetes (T2D). This study included 20,712 T2D participants without prevalent diabetic microvascular complication (DMCs) and hematologic malignancy at baseline.

G protein-coupled receptors (GPCRs) are a superfamily of transmembrane proteins that initiate signaling cascades through activation of its G protein upon association with its ligand. In all mammalian vision, rhodopsin is the GPCR responsible for the initiation of the phototransduction cascade. Within photoreceptors, rhodopsin is bound to its chromophore 11-cis-retinal and is activated through the light-sensitive isomerization of 11-cis-retinal to all-trans-retinal, which activates the transducin G protein, resulting in the phototransduction cascade.

Telomere shortening has been linked to type 2 diabetes (T2D) and its complications. This study aims to determine whether leukocyte telomere length (LTL) could be a useful marker in predicting the onset of complications in patients suffering from T2D. Enrolled study subjects were 147 T2D patients.

Inositol polyphosphate-5-phosphatase E (INPP5E) is a 5-phosphatase critically involved in diverse physiological processes, including embryonic development, neurological function, immune regulation, hemopoietic cell dynamics, and macrophage proliferation, differentiation, and phagocytosis. Mutations in cause Joubert and Meckel-Gruber syndromes in humans; these are characterized by brain malformations, microphthalmia, situs inversus, skeletal abnormalities, and polydactyly. Recent studies have demonstrated the key role of INPP5E in governing intracellular processes like endocytosis, exocytosis, vesicular trafficking, and membrane dynamics.

Introduction Diabetes is a rapidly growing global health concern, with the World Health Organization (WHO) estimating that 300 million adults will have diabetes by 2025. This chronic condition is associated with complications, including nephropathy, retinopathy, neuropathy, cardiovascular disease, and diabetic foot ulcers (DFUs), which can lead to amputation. Diabetic septic foot (DSF), a severe form of diabetic foot disease, is defined by the WHO as the presence of infection, ulceration, or tissue destruction in the lower limb, often accompanied by neurological abnormalities, peripheral vascular disease, and metabolic complications of diabetes.
