The proceedings contain 45 papers. The topics discussed include: neuropeptide levels effect on blood pressure in chronic kidney disease patients with hypertension;dry weight gain and incidence of intradialytic hypertension: a cross-sectional study in rural hospital;why they don't take the pill: a qualitative study of antihypertensive medication nonadherence in East Borneo primary health care;antihypertensive effect of nigella sativa (Habbatus Sauda) supplementation in population with cardiometabolic risk factors: a systematic review and meta-analysis of randomized controlled trials;risk factors of peripheral artery disease in the hypertensive chronic kidney disease patients on hemodialysis;impact of day-to-day blood pressure variability to in-hospital mortality in patients with COVID-19 and efficacy of antihypertensive agents;and systolic blood pressure as risk factor associated with persisting proteinuria after delivery in women with preeclampsia.

Background and Purpose: Stroke is a serious complication of COVID-19. However, the risk factors for this complication are poorly understood. We hypothesize that genetic predisposition to cardioand cerebrovascular disease (CVD) leads to an increased risk of stroke in patients with COVID-19 infection. Methods: We evaluated data from a nested cohort study conducted within the UK Biobank focused on persons with documented COVID-19. Incident strokes (ischemic and hemorrhagic) were identified by combining inpatient data (including critical care and discharge diagnostic codes) and primary care data, the latter entered by providers within 30 days of a positive COVID-19 test. Genetic predisposition to CVD was evaluated through a polygenic risk score that integrated genomic information on 2,176 independent genetic risk variants for stroke, coronary artery disease and cardiometabolic risk factors. This score was divided into low (0-20th percentile), intermediate (20th- 80th percentile), and high (80 -100 percentile) genetic risk. Results: A total of 11,882 study participants (mean age 65.8, SD [8.6], female sex 6,306 [53.1%]) with documented COVID-19 infection were included in this study, including 99 (0.8%) persons that ustained a stroke during the infection. Compared to persons with low genetic predisposition to CVD, those with intermediate and high genetic risk had 35% (OR 1.35, 95%CI 1.14-1.55) and 2.4- fold (OR 2.38, 95% CI 1.71-3.05) higher risk of stroke (test for trend p=0.004). Sub-scoring analyses evaluating one polygenic risk score per CVD trait of interest indicated that genetic predisposition to hypertension (p=0.017) and smoking (p=0.03) were the most important genetic risk factors. Conclusions: Genetic predisposition to CVD is associated with a higher risk of stroke in persons with acute COVID-19 infection. Genetic risk factors for hypertension and smoking appear to mediate a significant portion of this association. Genetic information should be considered in the multiple ongoing efforts to create risk-stratification strategies to identify COVID-19 patients at high risk of stroke.

Background: Growing interest in very low carbohydrate diets, and in particular the ketogenic diet, has been met with some resistance. Important gaps exist regarding what diet to compare to the ketogenic diet. The objective of this study was to compare a Well Formulated Ketogenic Diet (WFKD) with a Mediterranean-Plus diet (Med-Plus;Mediterranean with emphasis on eliminating added sugars and refined grains), in a crossover study, stratified by diabetes status (T2D vs Prediabetes). Methods: The intervention involved having participants follow the WFKD and Med-Plus, for 12 weeks each, in random order. All meals were provided for the first 4 weeks of each diet phase (food delivery);then participants were responsible for purchasing and preparing their own foods (self-provided). The primary outcome was glycosylated hemoglobin (HbA1c). Secondary outcomes included weight, glucose as measured by continuous glucose monitor (CGM), and cardiometabolic risk factors, such as fasting insulin, glucose, and lipids. Results: Among participants randomized (n = 42), 33 had complete data at both diet phases (some missing data attributable to COVID disruptions). Participants were 60 ± 9 (mean ± sd) years of age, 61% men, with BMI 31 ± 5 kg/m2. Adherence for both diets was higher during the food delivery than the self-provided phase, but similar between diets for both phases. HbA1c concentrations were not significantly different between diets, but average CGM glucose levels were significantly lower during the WFKD compared to Med-Plus (p = 0.03). Additionally, WFKD induced a significantly greater decrease in triglycerides (-16% vs -5%, p = 0.02) and greater increase in LDL-C levels (10% vs -5%, p = 0.01), compared to Med-Plus. Weight change on WFKD vs Med-Plus was -8% vs -7% (p = 0.05). Sensitivity analyses largely confirmed the main findings. Conclusions: Participants improved in glucose control and weight management on both diets relative to baseline;however, glucose control was superior on the WFKD. Some caution is warranted when interpreting these results due to pandemic disruptions and a small sample size. A fair comparison of the two diets should also take into consideration non-glycemic effects.
