Proteinuria in early referral to spectral domain optical coherence tomography for macular edema detection in type 2 diabetes individuals: results from the Brazilian diabetes study.

BACKGROUND: Measurement of retinal thickness by optical coherence tomography (OCT) shows higher diagnostic accuracy for diabetic macular edema (DME) than fundus photography alone. The expanding gap between the rising number of type 2 diabetes (T2D) individuals and the availability of OCT devices demands a targeted selection of individuals at higher risk of DME who would benefit the most from early referral. We sought to appraise if proteinuria should be considered in a targeted referral of T2D individuals to OCT examination. METHODS: This study was a cross-sectional analysis of 576 consecutive patients enrolled in the Brazilian Diabetes Study between June/2016 and December/2021 who underwent OCT exam and urinalysis to assess ME and proteinuria status, respectively. Differences in the prevalence of DME between proteinuria groups and across a range of diabetic retinopathy (DR) stages were evaluated. RESULTS: Among 1134 eyes included in this analysis, the prevalence of proteinuria was 22% and 18.2% of eyes had DME. Proteinuria was related to an increased prevalence of DME (13.2% vs 38.7% for control vs proteinuria, respectively; p < .001), with an OR of 4.08 [95% confidence interval (CI): 2.50-6.64, p < .001), after adjustment for covariates. Proteinuria was independently related to DME also among eyes with non-apparent DR [OR: 2.82; 95%CI: 1.34-5.93; p = .003] and non-proliferative DR (OR of 5.94, 95%CI 2.13-16.62, p < .001). Fundus photography spotted only half of the DME cases detected by OCT. CONCLUSION: In T2D individuals, early referral to OCT examination should be pursued for all individuals with concurrent proteinuria. TRIAL REGISTRATION: ClinicalTrials.gov Identifier: NCT04949152.

Rationale and design of the Brazilian diabetes study: a prospective cohort of type 2 diabetes.

BACKGROUND: Optimal control of traditional risk factors only partially attenuates the exceeding cardiovascular mortality of individuals with diabetes. Employment of machine learning (ML) techniques aimed at the identification of novel features of risk prediction is a compelling target to tackle residual cardiovascular risk. The objective of this study is to identify clinical phenotypes of T2D which are more prone to developing cardiovascular disease. METHODS: The Brazilian Diabetes Study is a single-center, ongoing, prospective registry of T2D individuals. Eligible patients are 30 years old or older, with a confirmed T2D diagnosis. After an initial visit for the signature of the informed consent form and medical history registration, all volunteers undergo biochemical analysis, echocardiography, carotid ultrasound, ophthalmologist visit, dual x-ray absorptiometry, coronary artery calcium score, polyneuropathy assessment, advanced glycation end-products reader, and ambulatory blood pressure monitoring. A 5-year follow-up will be conducted by yearly phone interviews for endpoints disclosure. The primary endpoint is the difference between ML-based clinical phenotypes in the incidence of a composite of death, myocardial infarction, revascularization, and stroke. Since June/2016, 1030 patients (mean age: 57 years, diabetes duration of 9.7 years, 58% male) were enrolled in our study. The mean follow-up time was 3.7 years in October/2021. CONCLUSION: The BDS will be the first large population-based cohort dedicated to the identification of clinical phenotypes of T2D at higher risk of cardiovascular events. Data derived from this study will provide valuable information on risk estimation and prevention of cardiovascular and other diabetes-related events. CLINICALTRIALS.GOV IDENTIFIER: NCT04949152.

Dapagliflozin increases retinal thickness in type 2 diabetic patients as compared with glibenclamide: A randomized controlled trial.

AIM: In patients with type 2 diabetes mellitus (T2DM) a progressive thinning in the central retinal thickness (CRT) is mainly related to neuroretinal degeneration and occurs before the decline in visual acuity or capillary density. We investigated the change in CRT by optical coherence tomography (OCT) in T2DM patients after 12 weeks of treatment with dapagliflozin or glibenclamide. METHODS: Ninety-seven patients (57 ± 7 years) with T2DM and clinical or subclinical atherosclerosis were randomized 1:1 to dapagliflozin (10 mg/day) or glibenclamide (5 mg/day) on top of metformin XR 1.5 g/day. OCT was obtained in all patients enrolled in the study, both at the time of randomization and at the end of the study. RESULTS: Baseline and post-treatment values of fasting glucose and glycated hemoglobin were equivalent in the two arms. There was no difference in change in diabetic retinopathy status after therapy. The center subfield thickness changed by +2(6)µm in the dapagliflozin group and by -1(7) µm in the glibenclamide group (P = 0.001). CONCLUSION: A short-term treatment with dapagliflozin may increase CRT as compared with equivalent glycemic control with glibenclamide.

Precarização do trabalho do agente comunitário de saúde: um desafio para a gestão do SUS / Precariousness of the work of the Community health: a challenge for SUS management

INTRODUÇÃO: A discussão do tema precarização do emprego exige que sejam consideradas algumas conexões que envolvem as relações de trabalho e poder. OBJETIVO: estudar as condições de trabalho do agente comunitário de saúde. MATERIAL E MÉTODO: estudo descritivo com abordagem predominantemente qualitativa e teve como foco as formas de inserção no trabalho dos agentes comunitários de saúde de duas áreas do Rio Grande do Norte. RESULTADOS: a discussão da contratação do agente comunitário de saúde é mais complexa no que aparenta, pois ela não é resultado de uma simples decisão do setor saúde em contratar desta ou de outra forma. CONCLUSÃO: as secretarias municipais de saúde convivem com uma situação entre o reconhecimento do papel e da importância do agente comunitário de saúde nos serviços municipais e sua incapacidade, ou falta de vontade, de vincular esse profissionais de forma permanente à instituição e, o que é pior, sua incapacidade de vinculá-lo por meio de um contrato de trabalho que lhe garanta direitos, como férias, licenças, décimo terceiro salário, aposentadoria.
