A randomized controlled trial evaluating a theory driven, complex intervention centered on task sharing and mobile health to improve selfcare and outcomes in heart failure - The PANACEA-HF RCT: Design and rationale.

Background: We developed a three-pronged complex intervention to improve selfcare and deliver whole person care for patients with heart failure, underpinned by the 'extant cycle' theory - a theory based on our formative work.

Methods: This is a 3 centre, 2-arm, 1:1, open, adaptive stratified, randomized controlled trial. We included patients aged ≥ 18 years with heart failure, taking any of the key guideline directed medical treatments, with a history of or currently on a high ceiling diuretic.

Non-alcoholic fatty liver disease and diabetic retinopathy: Is there an association?

Background: Studies have not proven whether an association exists between diabetic retinopathy (DR) and non-alcoholic fatty liver disease (NAFLD). The reports from various parts of the world have not used uniform criteria, and hence, results are inconclusive. Both DR and NAFLD are common conditions encountered in primary care.

Molecular markers for early stratification of disease severity and progression in COVID-19.

COVID-19 infections have imposed immense pressure on the healthcare system of most countries. While the initial studies have identified better therapeutic and diagnostic approaches, the disease severity is still assessed by close monitoring of symptoms by healthcare professionals due to the lack of biomarkers for disease stratification. In this study, we have probed the immune and molecular profiles of COVID-19 patients at 48-h intervals after hospitalization to identify early markers, if any, of disease progression and severity.

The effect of l-arginine supplementation on amelioration of oxygen support in severe COVID-19 pneumonia.

Background & Aims: l-Arginine (l-Arg) has been shown to help reduce respiratory support requirements in coronavirus disease 2019 (COVID-19), in an Italian study. We investigated the effect of l-Arg supplementation on the reduction in respiratory support for patients with severe COVID-19 pneumonia in an Indian population.

Methods: A parallel-group, triple-blinded, randomized controlled trial (RCT) was conducted on patients with severe COVID-19 pneumonia on oxygen (O) support.
