ABSTRACT The recently proposed cardio-kidney-metabolic (CKM) framework underscores the interconnected nature of cardiovascular, renal, and metabolic diseases and represents an important step toward preventive, integrated care. However, its application in kidney care remains limited and dependent on additional supportive evidence. Chronic kidney disease (CKD) is often underrecognized in cardiovascular risk models and receives delayed attention within the CKM pathway. Nephrologists face unique challenges – including workforce shortages, late referrals, and fragmented care systems – particularly in lowand middleincome countries. Early […]

ABSTRACT Objective: To identify maternal and neonatal outcomes in pregnancies with early versus late gestational diabetes mellitus (GDM) diagnosis, considering healthcare access in a low- to middle-income area of Brazil. Subjects and methods: This retrospective study included women diagnosed with either early GDM (diagnosed before 20 weeks, based on fasting plasma glucose) or late GDM (diagnosed by 24-28 weeks, via oral glucose tolerance test), according to the IADPSG criteria, who received prenatal care at a hospital in southern Brazil. Maternal […]

Abstract Objective: To investigate the association of copeptin levels in the postpartum period with previous gestational diabetes mellitus, as well as its cardiometabolic phenotypes and biomarkers. Methods: In this cross-sectional analysis, women followed at a specialized gestational diabetes mellitus outpatient clinic were studied. Eligibility criteria included age ≥ 18 years and body mass index > 25 kg/m2. Participants were divided into two groups: those with (n = 42) and without gestational diabetes mellitus (n = 43). In the postpartum period […]

ABSTRACT Objective: This study investigated the acute effects of cocoa flavanol (CF) supplementation on glucose homeostasis, aerobic performance, and lactate concentration in rats with type 1 diabetes mellitus (T1DM), type 2 diabetes mellitus (T2DM), and normoglycemia (NORM). Materials and methods: The study included 28 male Wistar rats (220-290 g). Induction of T1DM (n = 8) was achieved through intraperitoneal injection of streptozotocin, while T2DM (n = 10) was induced using an ad libitum high-fat diet combined with a fructose-rich beverage. […]

ABSTRACT Objective: Diabetic neuropathy (DN) is an important complication of diabetes mellitus. Autophagy is considered to be potentially involved in the regulation of DN. Metformin is broadly utilized in the first-line treatment of diabetes. The present work aimed to assess whether and how metformin exerts protective effects in DN. Materials and methods: A DN rat model induced by streptozotocin (STZ) was established. Metformin was administered to examine its effect on sciatic nerve pathology, and the possible mechanisms involved in this […]

ABSTRACT Objective To identify predictors of mental health disorders and self-care worsening in patients with diabetes through 15 months of COVID-19 pandemic. Subjects and methods Prospective study following patients with type 1 and type 2 diabetes during the COVID-19 pandemic in Southern Brazil. Participants were evaluated through phone calls in two moments: first three months of the outbreak, and 15 months later. The outcomes were the assessment of worsening in mental health disorders (increase ≥ 10% in the total score […]

ABSTRACT Objective To evaluate, characterize and search for trends in the underreporting of diabetes mellitus (DM) as the cause of death in Bauru, São Paulo, Brazil, over 40 years. Subjects and methods This was a documental study. Clinical and mortality data were collected from individuals known to have type 1 (DM1) and type 2 diabetes mellitus (DM2), residing in Bauru, State of São Paulo, followed at a local endocrinology clinic from 1982 to 2021, who deceased during this period. Results […]

ABSTRACT Objective: This study sought to investigate the regulation of long noncoding RNA (lncRNA) XIST on the microRNA (miR)-101-3p/vascular endothelial growth factor A (VEGFA) axis in neovascularization in diabetic retinopathy (DR). Materials and methods: Serum of patients with DR was extracted for the analysis of XIST, miR-101-3p, and VEGFA expression levels. High glucose (HG)-insulted HRMECs and DR model rats were treated with lentiviral vectors. MTT, transwell, and tube formation assays were performed to evaluate cell viability, migration, and angiogenesis, and […]

ABSTRACT The proportion of deaths attributable to cancer is rising, and malignant neoplasms have become the leading cause of death in high-income countries. Obesity and diabetes are now recognized as risk factors for several types of malignancies, especially endometrial, colorectal, and postmenopausal breast cancers. Mechanisms implicated include disturbances in lipid-derived hormone secretion, sex steroids biosynthesis, hyperinsulinemia, and chronic inflammation. Intentional weight loss is associated with a mitigation of risk for obesity-related cancers, a phenomenon observed specially with bariatric surgery. The […]

ABSTRACT Objectives: To evaluate the effect of sitagliptin treatment in early type 2 diabetes mellitus (T2DM) and the impact of different macronutrient compositions on hormones and substrates during meal tolerance tests (MTT). Materials and methods: Half of the drug-naive patients with T2DM were randomly assigned for treatment with 100 mg of sitagliptin, q.d., or placebo for 4 weeks and then submitted to 3 consecutive MTT intercalated every 48 h. The MTTs differed in terms of macronutrient composition, with 70% of […]

ABSTRACT The prevalence of diabetes mellitus is increasing and is related to sedentary lifestyles and obesity. Many studies were published on the effect of lifestyle interventions on glucose regulation and delay the onset of diabetes in adults with impaired glucose tolerance (IGT) or prediabetes. This study aimed to investigate the role of lifestyle interventions in individuals with IGT or prediabetes using a meta-analytic approach. PubMed, Embase, and the Cochrane Central Register of Controlled Trials databases were searched from their inception […]

ABSTRACT Objective: Flash glucose monitoring (FGM) is increasingly used in type 1 diabetes mellitus (T1D) management. This study aimed to assess glycated hemoglobin (HbA1c) and body mass index (BMI) in the first year of FGM use in patients with T1D and to identify predictive factors of benefit associated with its use. Subjects and methods: Retrospective study of T1D patients, using FGM for ≥ 6 months and under intensive insulin therapy with multiple daily injections. Results: In 179 patients with a […]
