Objective: The aim of this study was to determine the haemodynamics of the intrarenal arteries from the relationship between resistivity index (RI) and kidney function, and to identify the predictors of high RI among patients with diabetic nephropathy (DN) and those with diabetes mellitus (DM) without DN.
Methods: This was a cross-sectional survey of 133 participants, comprising 40 subjects with DM without DN, 53 with DM with DN and 40 healthy controls. Information obtained was demographics, lifestyle, medical and medication histories, while anthropometric and blood pressure measurements were taken. Albuminuria and estimated glomerular filtration rate were determined and RI was measured using a Doppler ultrasound scan.
Results: The mean intrarenal artery RIs were higher among the patients with DM without DN (0.60 ± 0.04) and the group with DM with DN (0.61 ± 0.04) than in the controls (0.56 ± 0.04) (p = 0.02). Glycated haemoglobin (HbA1c) predicted high RI in the DM without DN group (OR 2.81; CI: 1.73–9.03) while hypertension (OR 3.60; CI: 1.06–12.22) predicted high RI in the DM with DN group.
Conclusion: Elevated intrarenal artery RI was prevalent among patients with DM without DN and those with DM with DN, while elevated HbA1c level and hypertension predicted elevated RI in subjects with DM without DN and those with DM with DN.

Introduction: A daily handful of walnuts every day for two years modestly lowered levels of low-density lipoprotein (LDL) cholesterol, known as ‘bad cholesterol’ and reduced the number of total LDL particles and small LDL particles in healthy, older adults, according to a study in the American Heart Association’s flagship journal Circulation.

Introduction: Up to three cups of coffee per day is associated with a lower risk of stroke, fatal heart disease and all-cause mortality in a population without diagnosed heart disease over 10 to 15 years, according to a large study presented at the European Society of Cardiology Congress 2021. Coffee may reverse some of the detrimental effects of ageing on the heart, said the lead author. Imaging analysis indicated that compared with participants who did not drink coffee regularly, daily consumers had healthier sized and better functioning hearts.

Introduction: Middle- to older-aged adults who ate at least three servings of whole grains daily had smaller increases in waist size, blood pressure and blood sugar levels over time compared with those who ate less than one-half serving per day, according to researchers at the Jean Mayer USDA Human Nutrition Research Center on Aging (HNRCA) at Tufts University, USA.

Introduction: The 5:2, or intermittent fasting diet, is just as effective as a conventional energy-restricting diet, enabling women greater choice and flexibility when it comes to weight loss, found a University of South Australia study in the American Journal of Clinical Nutrition. The 5:2 diet allows five days of normal eating each week while substantially restricting calories over two days a week, as opposed to a typical diet that requires moderate energy restrictions daily.

Introduction: Use of the diabetes drug metformin, before a diagnosis of COVID-19, is associated with a three-fold decrease in mortality in COVID-19 patients with type 2 diabetes, according to a racially diverse study at the University of Alabama at Birmingham. Diabetes is a significant co-morbidity for COVID-19. ‘This beneficial effect remained, even after correcting for age, sex, race, obesity and hypertension or chronic kidney disease and heart failure,’ said Dr Anath Shalev, director of UAB’s Comprehensive Diabetes Centre and leader of the study.

Introduction: Breakthrough results for empagliflozin confirm EMPERORPreserved as the first successful trial for heart failure with preserved ejection fraction (HFpEF), Boehringer Ingelheim and Eli Lilly and Company have announced. Full results from the EMPEROR-Preserved trial were presented at the European Society of Cardiology (ESC) Congress 2021 on 27 August.
