Rationale, design, and baseline characteristics of the Salt Substitute in India Study (SSiIS): The protocol for a double-blinded, randomized-controlled trial.
Reduced-sodium, added-potassium salt substitutes have favorable effects on blood pressure, but have not been tested in India. The Salt Substitute in India Study (SSiIS) is a double-blinded, randomized-controlled trial designed to investigate the effects of reduced-sodium, added-potassium salt substitution to replace usual cooking salt use and blood pressure (BP) among hypertensive patients in rural India. The primary objective is to assess effects on systolic blood pressure at 3 months. ⋯ The overall mean average 24-hour urinary sodium excretion was 2825 (SD, 1166) mg/L, which corresponds to a urinary salt excretion of 10.4 g/d. Baseline findings suggest sodium intake in this population significantly exceeds World Health Organization recommendations. The SSiIS trial has successfully recruited participants and is well placed to determine whether salt substitution is an effective means of lowering blood pressure for rural Indian patients with hypertension.

Observational StudyUse of distinct anti-hypertensive drugs and risk for COVID-19 among hypertensive people: A population-based cohort study in Southern Catalonia, Spain.
The use of some anti-hypertensive drugs in the current COVID-19 pandemic has become controversial. This study investigated possible relationships between anti-hypertensive medications use and COVID-19 infection risk in the ambulatory hypertensive population. This is a population-based retrospective cohort study involving 34 936 hypertensive adults >50 years in Tarragona (Southern Catalonia, Spain) who were retrospectively followed through pandemic period (from 01/03/2020 to 30/04/2020). ⋯ Considering anti-hypertensive drugs, receiving diuretics (HR: 1.22; 95% CI: 0.90-1.67; P = .205), calcium channel blockers (HR: 1.29; 95%CI: 0.91-1.82; P = .148), beta-blockers (HR: 0.97; 95% CI: 0.68-1.37; P = .844), and angiotensin-converting enzyme inhibitors (HR: 0.83; 95% CI: 0.61-1.13; P = .238) did not significantly alter the risk of PCR-confirmed COVID-19, whereas receiving angiotensin II receptor blockers was associated with an almost statistically significant reduction risk (HR: 0.67; 95% CI: 0.44-1.01; P = .054). In conclusion, our data support that receiving renin-angiotensin-aldosterone system inhibitors does not predispose for suffering COVID-19 infection in ambulatory hypertensive people. Conversely, receiving angiotensin II receptor blockers could be related with a reduced risk.
