Background & objectives We aimed to assess the impact of COVID-19-related disruptions on ongoing and future projects related to neuroscience research and young researchers in India. Methods We conducted a countrywide online survey using a structured, self-administered questionnaire involving medical trainees, post-doctoral fellows, PhD students, early career faculty members and basic neuroscience researchers. The purpose was to assess the impact of the COVID-19 pandemic on the respondents' ongoing/planned research activities and capture their concerns related to future research. ⋯ Interpretation & conclusions In our survey, an overwhelming majority of the respondents reported that the pandemic adversely impacted their study. This trend was independent of sex, designation, and research output of individual subjects. The serious impact of the COVID-19 pandemic on neurosciences research warrants the attention and concerted efforts of the research supervisors, institutional heads, funding agencies and other stakeholders.

Background & objectives Despite the evidence of population differences in miRNA expression, limited information is available about the expression profile of miRNAs in Indian tuberculosis (TB) patients. The present study aimed to investigate the expression profile of candidate serum exosomal microRNAs in Indian patients with and without HIV-TB coinfection. Methods The pool samples of serum exosomes of study participants (HIV-TB coinfection, extra-pulmonary TB, HIV mono-infection, pulmonary TB) and healthy humans were processed for the isolation of total RNA followed by miRNA analysis using miRCURY LNA human focus PCR panel by real-time PCR. ⋯ The set of three (hsa-let-7i-5p, hsa-miR-24-3p, hsa-miR-92a-3p), three (hsa-miR-20a-5p, hsa-let-7e-5p, hsa-miR-26a-5p) and four (hsa-miR-21-5p, hsa-miR-19a-3p, hsa-miR-19b-3p, hsa-miR-146a-5p) miRNAs were exclusively significantly differentially expressed in study participants with HIV-TB coinfection, extra-pulmonary TB and pulmonary TB, respectively. Most of the target genes of exclusively differentially expressed miRNAs were enriched in pathways in cancer, MAPK signalling pathway and Ras signalling pathway. Interpretation & conclusions The present study demonstrates a distinct expression profile of miRNAs in serum exosomes of the study participants and identified crucial miRNAs which may have a significant impact on the biomarker analysis and pathogenesis of TB in Indian patients.

Background & objectives Candida spp. cause candidiasis in humans under conditions disrupting the host defence. While Candida albicans is the most reported cause of candidiasis, there is a surge in the incidence of infections by non-albicans Candida species (NACs), such as C. tropicalis, C. glabrata and C. auris. These species can infect all organs of the human body. ⋯ This resource is integrated with visualization tools. Interpretation & conclusions EpiCandIn will be useful for public health researchers and policymakers as it will help them gain insights into the emerging trends and management of Candida infections in India. It can be accessed at epicandin.bicnirrh.res.in.

Background & objectives Burden estimates of enteric fever are required to make policy decisions on introducing typhoid vaccine in India. Incidence, antimicrobial susceptibility, and out-of-pocket expenditure (OOPE) of enteric fever are estimated in Chandigarh, India. Methods A hybrid (facility and community-based) surveillance system was set up at a secondary care hospital to enrol patients above six months of age, hospitalized with fever, from a defined catchment population from May 2018 to March 2020. ⋯ Paratyphi [INR 8696.6 (USD 116)] was significantly higher than the individuals infected with S. Typhi [INR 7309 (USD 97.5), P=0.01], and among cases who were hospitalized for more than seven days [INR 12,251 (USD 163.3)] as compared with those with a stay of 3-7 days [INR 8038.2 (USD 107.2)] or less than three days [INR 5327.8 (USD 71), P<0.001]. Interpretation & conclusions There was a high incidence of enteric fever, high OOPE, and resistance to ciprofloxacin.

Background & objectives Mumps, a contagious disease caused by the mumps virus (MuV) involves parotid gland inflammation, with potential complications affecting organs other than the parotid glands and central nervous system. Despite successful vaccination, a resurgence of mumps occurred, raising concerns about vaccine effectiveness. This study aimed to examine the entire genome of a representative MuV genotype C from Dibrugarh, Assam, and compare it with references to detect genetic variations in the circulating strain. ⋯ Despite mumps' global effect, genomic studies are limited, particularly in north-east. Our study provides first comprehensive whole-genome report on circulating MuV genotype C in Assam. This research contributes vital genomic data, filling gaps in MuV genetic epidemiology, supporting global research, and assessing vaccine effectiveness.
