Factors associated with stigma and manifestations experienced by Indian health care workers involved in COVID-19 management in India: A qualitative study.

Healthcare personnel who deal with COVID-19 experience stigma. There is a lack of national-level representative qualitative data to study COVID-19-related stigma among healthcare workers in India. The present study explores factors associated with stigma and manifestations experienced by Indian healthcare workers involved in COVID-19 management.

Determinants of Turn-Around-Time for Early Infant Diagnosis of HIV Testing: Retrospective Analysis of National Level PCR Testing Data.

India has been implementing one of the biggest Early Infant Diagnosis (EID) of HIV intervention globally. The turn-around-time (TAT) for EID test is one of the major factors for success of the program. This study was to assess the turnaround time and its determinants.

Upregulation of Profilin 2 on HDAC6 overexpression in mouse GC-1 cells and its putative role in germ cell migration in the testis.

Previous reports from this laboratory have demonstrated the involvement of histone deacetylase 6 (HDAC6) in sperm motility. As the presence of HDAC6 has also been reported in the earlier stage germ cells, studies were undertaken to explore its role during these stages of spermatogenesis. HDAC6 was overexpressed in GC-1spg cells, which represent the stage between type B spermatogonia and primary spermatocyte, and its effect on germ cell transcriptome was investigated by microarray.

Human leukocyte antigens class I and class II alleles associated with vertical human immunodeficiency virus transmission - an exploratory study from Mumbai, India.

Background Human leukocyte antigens (HLA) an important host genetic factor is responsible for influencing human immunodeficiency virus/acquired immunodeficiency syndrome (HIV/AIDS) transmission and disease progression. Contributions of HLA I and II alleles have not been reported in the Indian population with respect to vertical HIV transmission. Aim In the current study we determined the frequencies of HLA class I and class II alleles in a cohort of children exposed to HIV through their mothers.

Qualitative Examination of the Role and Influence of Mothers-in-Law on Young Married Couples' Family Planning in Rural Maharashtra, India.

Unmet need for family planning (FP) continues to be high in India, especially among young and newly married women. Mothers-in-law (MILs) often exert pressure on couples for fertility and control decision making and behaviors around fertility and FP, yet there is a paucity of literature to understand their perspectives. Ten focus group discussions (FGDs) were carried out with MILs of young married women (aged 18-29 years) participating in a couple-focused FP intervention as a part of a cluster-randomized intervention evaluation trial (the CHARM2 study) in rural Maharashtra, India.

Loss to follow-up of HIV-exposed infants for confirmatory HIV test under Early Infant Diagnosis program in India: analysis of national-level data from reference laboratories.

Background: Early Infant Diagnosis was launched in India in 2010 and its effect on the diagnosis of HIV-exposed infants needs to be assessed. The present study was done to find out the median age at DBS sample collection for early infant diagnosis and its trend over years, the median age at diagnosis of HIV among the HIV-exposed infants with DNA PCR tests, and the proportion of infants who completed testing cascades after detection of HIV-1 in a sample.

Methods: DNA PCR data (from 2013 to 2017) maintained at all regional reference laboratories in India was collated with each infant identified by a unique code.

Associations between Contraceptive Decision-Making and Marital Contraceptive Communication and use in Rural Maharashtra, India.

Women's contraceptive decision-making control is crucial for reproductive autonomy, but research largely relies on the Demographic and Health Survey (DHS) measure which asks who is involved with decision-making. In India, this typically assesses joint decision-making or male engagement. Newer measures emphasize female agency.

Evaluation of cytokine profile in cervicovaginal lavage specimens of women having asymptomatic reproductive tract infections.

Reproductive tract infections (RTIs) such as vaginal candidiasis and bacterial vaginosis (BV) are common among sexually active women and can be both symptomatic or asymptomatic. The microbiota of the reproductive tract triggers immune response at the cervicovaginal interface resulting in secretion of cytokines during the course of these RTIs. The objective of this study was to evaluate the cytokine profile in cervicovaginal lavage of women having asymptomatic vaginal infections.

Clinical Profile of SARS-CoV-2-Infected Neonates.

Background There are conflicting data on the mother-to-child transmission of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) and few studies have described the clinical course of neonates infected with SARS-CoV-2. Objectives This study investigates the mother-to-child transmission rate and clinical profile of SARS-CoV-2-infected newborns. Methods Data on 304 newborns of 301 mothers with coronavirus disease 2019 (COVID-19) were prospectively collected and analyzed.

Mechanisms of group B -mediated preterm birth: lessons learnt from animal models.

Unlabelled: Group B (GBS) is an opportunistic pathogenic bacterium which upon colonization in the female reproductive tract can cause preterm births, fetal injury, and demise. Several determinants for GBS pathogenesis have been explored so far through the studies using animal models ranging from mice to non-human primates. The results from these experimental data have identified outer membrane vesicles, β-hemolysin, hyaluronidase, and Cas9 of GBS as major virulence factors leading to preterm births.

Highly dampened HIV-specific cytolytic effector T cell responses define viremic non-progression.

This study reports on HIV-specific T cell responses in HIV-1 infected Viremic Non-Progressors (VNPs), a rare group of people living with HIV that exhibit asymptomatic infection over several years accompanied by stable CD4+ T cell counts in spite of ongoing viral replication. We attempted to identify key virus-specific functional attributes that could underlie the apparently paradoxical virus-host equilibrium observed in VNPs. Our results revealed modulation of HIV-specific CD4+ and CD8+ effector T cell responses in VNPs towards a dominant non-cytolytic profile with concomitantly diminished degranulation (CD107a+) ability.

Killer cell immunoglobulin-like receptor (KIR) gene contents: Are they associated with cervical cancer?

Killer cell immunoglobulin-like receptors (KIRs) are required for natural killer cell function against virus-infected cells or tumor cells. KIR gene content polymorphisms in Indian women with cervical cancer (CaCx) remain unexplored. Hence, we analyzed the frequencies of KIR genes, KIR haplotypes, and Bx subsets to draw their association with CaCx.

Association of traditional marital practices with contraceptive decision-making, couple communication, and method use among couples in rural Maharashtra, India.

In India, traditional social practices around marriage, such as non-involvement of prospective brides in choice of partner and timing of marriage, child/early marriage, dowry and , compromise women's agency at the time of marriage and may also affect contraceptive practices in marriage. This paper examines the associations between traditional marital practices and contraceptive behaviours, including women's control over contraceptive decision-making, couples' communication about contraception, and ever use of contraceptives, among married women aged 18-29 years ( = 1,200) and their husbands in rural Maharashtra, India. Multivariable logistic regression was used to examine the association between these marginalising social practices and family planning behavioural outcomes, adjusting for demographic and parity confounders.

Experiences and challenges during implementation of operational guidelines of Maternal Near Miss Review of the Government of India at tertiary hospitals in Maharashtra.

The Government of India released operational guidelines for Maternal Near Miss-Review (MNM-R) in December 2014 for implementation at all the tertiary hospitals in India. An implementation research study was conducted at two selected tertiary hospitals in Maharashtra to assess the feasibility of implementation of the MNM-R guidelines at these hospitals and document the experiences and challenges during this process. The study findings suggest that for implementation of MNMR guidelines at these tertiary hospitals, there is need of dedicated staff; revision of MNM facility based form and critical review of the criteria for identification of MNM cases.

Aged mice ovaries harbor stem cells and germ cell nests but fail to form follicles.

Background: We recently published evidence to suggest that two populations of stem cells including very small embryonic-like stem cells (VSELs) and ovarian stem cells (OSCs) in ovary surface epithelium (OSE) undergo proliferation/differentiation, germ cell nests (GCN) formation, meiosis and eventually differentiate into oocytes that assemble as primordial follicles on regular basis during estrus cycle. Despite presence of stem cells, follicles get exhausted with advancing age in mice and result in senescence equivalent to menopause in women. Stem cells in aged ovaries can differentiate into oocytes upon transplantation into young ovaries, however, it is still not well understood why follicles get depleted with advancing age despite the presence of stem cells.

Evaluation of a gender synchronized family planning intervention for married couples in rural India: The CHARM2 cluster randomized control trial.

Background: Despite calls for gender transformative family planning interventions to increase male engagement and female reproductive agency, there is limited research involving rigorous evaluation of the integration of these approaches. CHARM2 (counseling Husbands and wives to Achieve Reproductive Health and Marital Equity) builds upon a prior three-session male engagement intervention by integrating female-focused sessions emphasizing women's choice and agency (i.e.
