Projected impact of fast-tracking of anti-retroviral treatment coverage on vertical transmission of HIV in India.

One of the five high-level goals under Phase V of the National AIDS and STD Control Programme (NACP) of the Government of India is the elimination of vertical transmission of HIV. In this paper, we estimate the potential impact of maintaining and enhancing the anti-retroviral treatment under the NACP in terms of averting new infections and vertical transmission rates vis-à-vis no intervention scenario. We used India's HIV Estimates 2022 models to create treatment coverage scenarios of no interventions, status quo, business as usual, on-track and fast-track scenarios from 2023 to 2030.

Association between COVID-19 Vaccination (ChAdOx1-S) and Thromboembolic, Thrombocytopenic, Hemorrhagic Events: A Systematic Review and Meta-analysis of Analytical Epidemiological Studies.

We conducted a systematic review of analytical epidemiological studies to assess the association between ChAdOx1-S vaccination and thromboembolic, thrombocytopenic, and hemorrhagic events. We searched Medline, Embase, Google Scholar, WHO-COVID-19 database, and medRxiv for studies evaluating the association between ChAdOx1-S and vascular events. Primary outcomes of interest were cerebral venous sinus thrombosis, peripheral venous thrombosis (PVT), and thrombocytopenia.

"TB drug stock planning in advance is a futile activity" health system's perceived challenges and suggested solutions pertaining to Nikshay Aushadhi portal in central India.

Background: The National TB elimination programme (NTEP) is facilitating sub-national certification of "TB Free" status with benchmarks at every 20% reduction in incidence from the baseline of 2015. Drug consumption/sale is essential criteria to claim for the award. During the certification process in 10 districts of Madhya Pradesh in 2022, it was found that Nikshay Aushadhi (a web-based supply chain management portal) entries were incomplete or vacant in most of the districts and it was observed that quarterly drug requests were not sent using Nikshay Aushadhi.

Safety profile of BCG revaccination for COVID prevention among elderly individuals in India.

BCG vaccination is known to be safe in infants and a part of immunization schedule in high tuberculosis (TB) burden countries. In the conquest to bring down the severity of the COVID 19 pandemic, many drugs were repurposed in research mode including BCG vaccination/revaccination in various populations. We did a study among the elderly population (>60 years of age) to assess the role of BCG revaccination in preventing the severity of COVID 19 disease.
