Abstract
Diagnosis of type 2 diabetes and prediabetes is mandatory. Chronic hyperglycemia in diabetes is associated with long-term micro- and macrovascular as well as with neurological complications. Prediabetes predisposes patients to develop diabetes and macrovascular disease.
Diagnosis of diabetes is established on (at least) one of the following criteria: a fasting plasma glucose ≥ 126 mg/dl (7.0 mmol/l), a casual plasma glucose ≥ 200 mg/dl (11.1 mmol/l) in the presence of symptoms, a 2-h plasma glucose during the 75-g oral glucose tolerance test (OGTT) ≥ 200 mg/dl (11.1 mmol/l) and/or an HbA1c ≥ 6.5%.
Prediabetes is defined by the Position Statement of the American Diabetes Association as a fasting plasma glucose between 100 and 125 mg/dl (5.6 - 6.9 mmol/l) [a condition called Impaired Fasting Glucose] and/or by a 2-h plasma glucose during OGTT 140 - 199 mg/dl (7.8 - 11.0 mmol) [Impaired Glucose Tolerance] and/or a HbA1c level 5.7 - 6.4%, with however some potential discordance between tests.
The threshold of fasting plasma glucose defining Impaired Fasting Glucose as well as the adequacy of HbA1c as a correct diagnostic tool for prediabetes is still debated.

Advancing Diabetic Wound Healing: Mechanisms and Interventions
In recent years, diabetic wounds have become a global health concern with the increase in the incidence of diabetes. Diabetic wounds are a kind of chronic and refractory ulcer. It is generally due to the microcirculatory disturbances and the reduced levels of endogenous growth factors. Delayed cutaneous wound healing is ...read more
Oxidative and inflammatory responses in the development of secondary diabetic complications
Diabetes, along with its associated secondary complications, represents a significant global health challenge, contributing significantly to morbidity and mortality. Unhealthy lifestyle habits, reduced physical activity, environmental pollutants, and stress are pivotal factors in the onset of diabetes, particularly type-2 diabetes. Poorly managed hyperglycemia can lead to various complications, including neuropathy, ...read more
