An Analysis of Levels and Trends in HIV Prevalence Among Pregnant Women Attending Antenatal Clinics in Karnataka, South India, 2003-2019.

Background And Objective: Periodic tracking of the trends and the levels of HIV prevalence at regional and district levels helps to strengthen a state's HIV/AIDS response. HIV prevalence among pregnant women is crucial for the HIV prevalence estimation of the general population. Karnataka is one of the high HIV prevalence states in India.

Space time analysis of dengue fever diagnosed through a network of laboratories in India from 2014-2017.

Background & Objectives: The Department of Health Research and the Indian Council of Medical Research, Government of India, have established Virus Research and Diagnostic Laboratory Network (VRDLN) to strengthen the laboratory capacity in the country for providing timely diagnosis of disease outbreaks. Fifty-one VRDLs were functional as on December 2017 and had reported about dengue fever across Indian states. The objectives of the study were to detect space time clusters and purely temporal clusters of dengue using Kulldorff's SaTScan statistics using patient level information; and to identify regions at greater risk of developing the disease using Kriging technique aggregating at district level.

Epidemiology of chikungunya based on laboratory surveillance data-India, 2016-2018.

Background: We analysed the laboratory surveillance data generated by the network of virology laboratories from January 2016 to July 2018 to describe the epidemiology of chikungunya in India.

Methods: Suspected patients reporting to virology laboratories are investigated for the presence of immunoglobulin M (IgM) antibodies against chikungunya virus (CHIKV) as evidence of recent infection. We analysed the data to describe the distribution of seropositive individuals by time, place and demographic characteristics.

Epidemiology of dengue fever in India, based on laboratory surveillance data, 2014-2017.

Objectives: The Indian Council of Medical Research and the Department of Health Research have established a network of Virus Research and Diagnostic Laboratories (VRDL) to strengthen laboratory capacity in India. We analyzed the data generated by the 52 VRDLs during 2014-2017 to describe the epidemiology of dengue fever (DF) in India.

Methods: As per the laboratory protocol, suspected DF patients reporting to various hospitals where VRDLs are located, or samples from suspected DF outbreaks are investigated for the presence of NS1 antigen or IgM antibodies against dengue.

Metal-Rich Oxametallaboranes of Group 5 Metals: Synthesis and Structure of a Face-Fused μ-Boride Cluster.

Aerobic oxidation of metallaborane compounds is an unexplored field apart from the few reports on accidental oxidation leading to oxametallaboranes. An effective method for the synthesis of group 5 oxametallaboranes has been developed by the oxidation of [(Cp*M)(BH)] (M = Ta/Nb) (Cp* = η-CMe). The reaction of [(Cp*M)(BH)] (M = Ta/Nb) with O gas at room temperature yielded oxametallaboranes [(Cp*M)(BHO)] (for 1, M = Nb; for 2, M = Ta).
