Brazilian Morus nigra

Morus nigra has been used popularly for several proposes, including diabetic. In an attempt to support medicinal value, the acute hypoglycemic, hypolipidemic, and antioxidant effects of the ethanolic extract of Morus nigra (EEMn 200 or 400 mg/kg b.w.) were evaluated in normal and alloxan-induced diabetic treated for 14 days. Serum biochemical and antioxidant analysis were performed at the end of experiment. Oral glucose tolerance test was performed at 10th and 15th days. Chromatographic analysis by HPLC-DAD of EEMn was performed. Insulin was used as positive control to glycemic metabolism as well as fenofibrate to lipid metabolism. EEMn (400 mg/kg/day) reduced fasting and postprandial glycaemia, improved oral glucose tolerance, and reduced lipolysis and proteolysis in diabetic rats. EEMn decreased the blood levels of total cholesterol and increased HDL level when compared to the diabetic control rats. At higher levels, EEMn reduced triglycerides and VLDL levels in diabetic rats. Also, EEMn reduced malondialdehyde and increased the reduced glutathione levels in liver of diabetic rats. Chromatographic analysis identified the presence of the flavonoids rutin, isoquercetin, and kaempferitrin. Acute EEMn treatment reduced hyperglycemia, improved oral glucose tolerance, and minimized dyslipidemia and oxidative stress leading to a reduction in atherogenic index in alloxan-induced diabetic rats

Uso de inibidores do cotransportador sódio-glicose 2 e sua relação com infecções geniturinárias

Introdução: Os Inibidores do Cotransportador Sódio-Glicose 2 (SGLT2) representam uma classe de antidiabéticos que têm se apresentado como uma alternativa promissora para o controle glicêmico de pacientes diabéticos. Ademais, sua aplicação estende-se ao tratamento de indivíduos com insuficiência cardíaca sintomática, atribuída aos efeitos de depleção de volume e às propriedades cardioprotetoras associadas. Todavia, surge um importante questionamento clínico sobre a possível relação entre o aumento da excreção urinária de glicose e o potencial incremento nas taxas de bacteriúria, bem como outras manifestações de infecções geniturinárias, incluindo infecções do trato urinário (ITU). Objetivo: Investigar, interpretar e revisar os achados sobre o uso de inibidores do SGLT2, averiguando e quantificando a incidência de infecções geniturinárias nesses pacientes ao decorrer do tratamento. Metodologia: Utilizou-se a base Medical Literature Analysis and Retrieval System Online (MEDLINE/PubMed), sob os descritores Urinary Tract Infection AND Sodium Glucose Co-Transporter 2 Inhibitor, com seleção de artigos de revisão e artigos originais nos últimos seis anos, seguindo os critérios de elegibilidade. Foram encontrados 93 artigos, dos quais foram selecionados 46 elegíveis. Resultados: Ao analisar os dados e evidências apresentados, infere-se que, embora haja um aumento na taxa de infecções devido à glicosúria induzida por esses agentes farmacológicos, os benefícios associados a esses inibidores emergem como elementos mais preponderantes. Os inibidores do SGLT2 demonstraram eficácia notável no controle glicêmico e na redução de eventos cardiovasculares, além de proporcionarem benefícios renais. A compreensão holística do perfil de riscos e benefícios sugere que os ganhos terapêuticos superam os potenciais riscos inerentes, consolidando assim a importância e a viabilidade do uso desses inibidores no manejo clínico de pacientes com diabetes mellitus tipo 2

Development and validation of the MMCD score to predict kidney replacement therapy in COVID-19 patients

Abstract Background Acute kidney injury (AKI) is frequently associated with COVID-19, and the need for kidney replacement therapy (KRT) is considered an indicator of disease severity. This study aimed to develop a prognostic score for predicting the need for KRT in hospitalised COVID-19 patients, and to assess the incidence of AKI and KRT requirement. Methods This study is part of a multicentre cohort, the Brazilian COVID-19 Registry. A total of 5212 adult COVID-19 patients were included between March/2020 and September/2020. Variable selection was performed using generalised additive models (GAM), and least absolute shrinkage and selection operator (LASSO) regression was used for score derivation. Accuracy was assessed using the area under the receiver operating characteristic curve (AUC-ROC). Results The median age of the model-derivation cohort was 59 (IQR 47–70) years, 54.5% were men, 34.3% required ICU admission, 20.9% evolved with AKI, 9.3% required KRT, and 15.1% died during hospitalisation. The temporal validation cohort had similar age, sex, ICU admission, AKI, required KRT distribution and in-hospital mortality. The geographic validation cohort had similar age and sex; however, this cohort had higher rates of ICU admission, AKI, need for KRT and in-hospital mortality. Four predictors of the need for KRT were identified using GAM: need for mechanical ventilation, male sex, higher creatinine at hospital presentation and diabetes. The MMCD score had excellent discrimination in derivation (AUROC 0.929, 95% CI 0.918–0.939) and validation (temporal AUROC 0.927, 95% CI 0.911–0.941; geographic AUROC 0.819, 95% CI 0.792–0.845) cohorts and good overall performance (Brier score: 0.057, 0.056 and 0.122, respectively). The score is implemented in a freely available online risk calculator ( https://www.mmcdscore.com/ ). Conclusions The use of the MMCD score to predict the need for KRT may assist healthcare workers in identifying hospitalised COVID-19 patients who may require more intensive monitoring, and can be useful for resource allocation
