Characterization of peripheral T helper 17 (Th17) cells phenotype in postmenopausal women with estrogen insufficiency.

Over the past few years, Th17 cells is considered a key player in osteoporosis pathogenesis. Although extensively studied in murine models, comprehensive Th17 cell characterization in osteoporotic women is elusive. We thus aimed to examine peripheral Th17 cells frequency and phenotypes in healthy and osteoporotic women. Our results demonstrated that Th17 cells were primarily CD4+CD45RA-CCR7-HALDR+CCR6lowT-cells. Compared to Pre-N, Post-L showed increased proportion of Th17 with concomitant decrease in Th1 cells. The Th17 cells frequency in effector memory CD4+ T cells was significantly elevated in Post-N with a decrease of Th1 cells in effector memory subsets compared to Pre-N and Post-L. Both Post-N and Post-L had decreased frequency of dual positive Th1-Th17 cells and increased HLA-DR expression on Th17 cells compared to Pre-N. Thus, our study demonstrates increased Th17 cells frequency and reduced Th1 cells frequency with effector memory phenotype in postmenopausal women with estrogen insufficiency and correlates with aging process.

Challenges in screening for sickle cell disease among newborns from the tribal region of Palghar, Maharashtra during the COVID-19 pandemic.

BACKGROUND OBJECTIVES: Despite several adversities imposed by the COVID-19 pandemic, it was crucial to sustain research having public health relevance such as investigations around sickle cell disease (SCD). Against this background, an ongoing ICMR-multicentric study for newborn screening of SCD in the tribal population at Model Rural Health Research Unit (MRHRU-Dahanu) in Palghar District, Maharashtra constituted the current study setting. This was a descriptive study wherein, certain measures were undertaken and strategies were developed in view of the challenges in newborn screening for SCD due to the COVID-19 pandemic during December 2019-September 2021 at Sub District Hospital, MRHRU-Dahanu. METHODS: During the onset of the pandemic, (December 2019-March 2020), the follow up was possible in 26.7 per cent (20/75) of the newborns. Subsequently, challenges such as travel restrictions, fear of COVID-19, shortage of staff were experienced with respect to enrolment and follow up visits. RESULTS: After implementing certain pragmatic strategies (ASHA involvement, usage of virtual platform and flexible visits), follow up rate increased to 47.5 per cent (66/139) between July 2020-April 2021 (post first lockdown) and to 66 per cent (65/98) during the second wave (May 2021-August 2021). INTERPRETATION CONCLUSIONS: The study emphasizes the importance of network building, use of virtual platform and engaging health workers in tribal settings. Such pragmatic approaches have the potential to pave a path for further implementation research involving specific interventions to improve health outcomes in tribal settings.

Outcomes in neonates born to mothers with COVID-19 during the second wave in India.

COVID-19 pandemic has affected all age groups globally including pregnant women and their neonates. The aim of the study was to understand outcomes in neonates of mothers with COVID-19 during the first and second waves of COVID-19 pandemic. A retrospective analysis of 2524 neonates born to SARS-CoV-2-infected mothers was conducted during the first wave (n = 1782) and second wave (n = 742) of the COVID-19 pandemic at five study sites of the PregCovid registry in Maharashtra, India. A significant difference was noted in preterm birth, which was higher in the second wave (15.0%, 111/742) compared to the first wave (7.8%, 139/1782) (P < 0.001). The proportion of neonates requiring NICU admission was significantly higher in the second wave (19.0%, 141/742) as compared to that in the first wave (14.8%, 264/1782) (P < 0.05). On comparing regional differences, significantly higher neonatal complications were reported from Mumbai metropolitan region (P < 0.05). During the second wave of COVID-19, birth asphyxia and prematurity were 3.8- and 2.1-fold higher respectively (P < 0.001). Neonatal resuscitation at birth was significantly higher in second wave (3.4%, 25/742 vs 1.8%, 32/1782) (P < 0.05). The prevalence of SARS-CoV-2 infection in neonates was comparable (4.2% vs 4.6%) with no significant difference between the two waves. CONCLUSION: Higher incidence of adverse outcomes in neonates born to SARS-CoV-2-infected mothers in the second wave of COVID-19 as compared to the first wave. TRIAL REGISTRATION: PregCovid study is registered with the Clinical Trial Registry of India (CTRI/2020/05/025423, Registered on 28/05/2020). WHAT IS KNOWN: • The second wave of COVID-19 was more lethal to pregnant women than the first wave. Newborns are at risk of developing complications. WHAT IS NEW: • Birth asphyxia, prematurity, and neonatal resuscitation at birth were significantly higher in the second wave as compared to those in the first wave of the COVID-19 pandemic in India.

Impact of intervention on nutritional status of under-fives in tribal blocks of Palghar District in Maharashtra, India.

Background: There is a need to improve their nutritional status of under-five children through specific targeted interventions. The present study discusses the impact of intervention on nutritional status among under-five children in Palghar district from Maharashtra. Objective: The objective is to improve the nutritional status of under-five children by implementing multi-component health and nutrition education intervention, focusing on dietary counseling and modification keeping in view the cultural and socio-economic status of population. Methods: A prospective pre- and post-intervention study was conducted in two tribal blocks. Total 480 under-five children were included in pre- and post-intervention survey each. Results: Exclusive breastfeeding rates improved from 48.9% to 50.5% and initiation of complementary feeding at 6 months improved from 48.3% to 72.5% in post intervention survey as compared to preintervention survey. Among other Infant and Young Child Feeding indicators, Minimum Meal Frequency increased significantly to 67.03% from 5.91% and minimum acceptable diet improved from 5.37% to 47.2% in post intervention survey. The prevalence of Severe Acute Malnutrition (SAM) reduced from 5.4% to nil whereas severe stunting and underweight significantly decreased by 17% and 8% respectively in post intervention survey. Severe anemia decreased from 16.24% to nil post intervention. Conclusion: The study reveals a substantial improvement in timely initiation of complementary feeds, nil cases of SAM, stunting, and underweight along with severe anemia in postintervention phase. This highlights the impact of multicomponent health and nutrition education interventions which may be adapted at a programmatic level to reduce child mortality and morbidity in India.

Clinical characteristics, outcomes, & mortality in pregnant women with COVID-19 in Maharashtra, India: Results from PregCovid registry.

Background & objectives: The PregCovid registry was established to document the clinical presentations, pregnancy outcomes and mortality of pregnant and post-partum women with COVID-19. Methods: The PregCovid registry prospectively collects information in near-real time on pregnant and post-partum women with a laboratory-confirmed diagnosis of SARS-CoV-2 from 19 medical colleges across the State of Maharashtra, India. Data of 4203 pregnant women collected during the first wave of the COVID-19 pandemic (March 2020-January 2021) was analyzed. Results: There were 3213 live births, 77 miscarriages and 834 undelivered pregnancies. The proportion of pregnancy/foetal loss including stillbirths was six per cent. Five hundred and thirty-four women (13%) were symptomatic, of which 382 (72%) had mild, 112 (21%) had moderate, and 40 (7.5%) had severe disease. The most common complication was preterm delivery (528, 16.3%) and hypertensive disorders in pregnancy (328, 10.1%). A total of 158 (3.8%) pregnant and post-partum women required intensive care, of which 152 (96%) were due to COVID-19 related complications. The overall case fatality rate (CFR) in pregnant and post-partum women with COVID-19 was 0.8 per cent (34/4203). Higher CFR was observed in Pune (9/853, 1.1%), Marathwada (4/351, 1.1%) regions as compared to Vidarbha (9/1155, 0.8%), Mumbai Metropolitan (11/1684, 0.7%), and Khandesh (1/160, 0.6%) regions. Comorbidities of anaemia, tuberculosis and diabetes mellitus were associated with maternal deaths. Interpretation & conclusions: The study demonstrates the adverse outcomes including severe COVID-19 disease, pregnancy loss and maternal death in women with COVID-19 in Maharashtra, India.

Discordance between TST and QFT-TBGold Plus for Latent Tuberculosis Screening among Under-Five Children: An Interim Analysis.

AIM: To analyze the agreement between tuberculin skin test (TST) and fourth-generation QuantiFERON (QFT)-TB Gold Plus [interferon gamma (INF-γ) release assays (IGRA)] for latent tuberculosis infection (LTBI) diagnosis among under-five children who are undernourished and/or who have history of contact with active tuberculosis (TB) patients. METHODS: Children from the age group of 6 months to 5 years (undernourished or tuberculosis household contacts) were screened through anganwadis (government playschools) and TB Health posts from Mumbai, India during September 2019 to January 2021. Both TST and QFT-TB Gold Plus test were carried out to diagnose LTBI. RESULTS: Out of the total 299, 35 (11.7%) (95% CI 8.1-15.3%) children tested positive by IGRA (QFT-TB Gold Plus) and 68 (22.7%) (95% CI 18.0-27.4%) by TST, suggestive of moderate concordance (κ = 0.483) between both tests. IGRA and TST showed moderate concordance in children <24 months (κ = 0.478). Moreover, 26 (21.1%) children with TB contact had both TST and IGRA positive with moderate concordance (κ = 0.550). A fair concordance (κ = 0.396) was observed between IGRA and TST in undernourished children. Also, 45 (15.0%) children showed discordance of which 39 (13.0%) had positive TST but negative IGRA and 6 (2.0%) had negative TST but positive IGRA. CONCLUSIONS: The study strongly recommends both TST and QFT-TB Gold Plus test for the diagnosis of LTBI in under-five children. A moderate concordance in children <24 months endorses the reliability of QFT-TB Gold Plus in diagnosing LTBI in this age group. This study highlights the need for screening undernourished children for LTBI to consider repeating IGRA testing for TST positives as per the window period and risk of ongoing exposure.

The current study focuses on discordance and concordance between tuberculin skin test (TST) and fourth-generation QuantiFERON (QFT)-TB Gold Plus [interferon gamma (INF-γ) release assays (IGRA)] for latent tuberculosis infection (LTBI) diagnosis among at-risk under-five children who are underweight and/or who have history of contact with active tuberculosis patients. The IGRA prevalence came out to be 11.7% (95% CI 8.1­15.3%) whereas the TST prevalence turned out to be 22.7% (95% CI 18.0­27.4%). A stronger concordance was observed between IGRA and TST among the age group of 2 to 5 years, and a relatively fair one for children below the age of 1 year. The present study strongly recommends to include both TST and IGRA test for the diagnosis of LTBI with respect to Indian pediatric population. This study also suggests the importance of repetition of IGRA for TST positive patients. Another vital opinion that is showcased in the present study is the inclusion of undernourished pediatric population residing in at-risk areas like urban slums for routine LTBI screening programs.

Clinical Characteristics, Management, and Short-Term Outcome of Neonates Born to Mothers with COVID-19 in a Tertiary Care Hospital in India.

INTRODUCTION: We describe the clinical characteristics, management, and short-term outcomes of SARS-CoV-2 neonates born to mothers with COVID-19 in a tertiary care hospital in Mumbai, India. METHODS: The study is a retrospective analysis of 524 neonates born to mothers with COVID-19 admitted from 14th April 2020 to 31st July 2020. RESULTS: SARS-CoV-2 infection was detected in 6.3% of the newborns of the mothers with COVID-19. No significant differences were observed between maturity at gestation, birth weight and sex of SARS-CoV-2 infected and noninfected newborns. The risk of sepsis was 4.09 [95% confidence interval (95% CI) 1.28-13.00] fold higher in the neonates with SARS-CoV-2 as compared to the noninfected group (p = 0.031). Poor feeding was significantly more common among SARS-CoV-2 infected neonates (12.1%) as compared to the noninfected neonates (2.7%) (p = 0.017). There was a total of 13 neonatal deaths, of which 3 deaths occurred in SARS-CoV-2 infected neonates (9%) while 10 (2.04%) in the SAR-CoV-2 negative group. The risk of neonatal death was higher in SARS-CoV-2 infected newborns [odds ratio (OR) 4.8; 95% CI 1.25-18.36]. CONCLUSION: Neonatal SARS-CoV-2 infection is observed in almost 6% of neonates born to mothers with perinatal COVID-19. There is a higher risk of adverse outcomes such as neonatal sepsis and death in the SARS-CoV-2 infected as compared to the noninfected neonates.

The current pandemic of COVID-19 has affected all the countries globally. However, the adverse impact of the pandemic is more seen in the low-income and middle-income countries (LMICs). Although there is evidence on the adverse impact of the SARS-CoV-2 on the health of mothers and neonates, the evidence is mainly from high-income countries. For reducing the mortality and morbidity due to COVID-19 in LMICs, there is a need to generate evidence from the LMICs. The present study is a part of the National Registry of pregnant women with COVID-19 in India (PregCovid registry). Our study demonstrates a higher risk of adverse outcomes such as neonatal sepsis and death in the SARS-CoV-2 infected as compared to the noninfected neonates. The study also showed the risk of SARS-CoV-2 infection in 6.3% of neonates born to mothers with COVID-19.

Significance of Vitamin D Binding Protein in Assessing Vitamin D Status Among Under-Five Children.

Despite ample sunshine, 50-90% Indian children have Vitamin D deficiency (VDD). This enigma of widespread VDD needs exploration especially among under-fives as physiological variations in Vitamin D Binding Protein (VDBP) levels could be potential confounders in the interpretation of total 25-hydroxyvitamin D [25(OH)D]. However, there is scarce information about relevance of VDBP levels in under-five age group. We therefore, explored association of VDBP levels among 1-5 year old children with VDD. Serum levels of 25(OH)D, VDBP, calcium, parathyroid hormone (PTH) and alkaline phosphatase were estimated in 210 apparently healthy children in the age group of 1-5 years. VDD was defined as serum 25(OH)D levels < 20 ng/ml as per the IOM classification. VDBP levels were classified as low if levels were < 168 µg/ml as per the kit. The prevalence of VDD was 79.5% (n = 167) and VDBP levels were low in 48.6% (n = 102) of children. 25(OH)D levels correlated positively with VDBP (r = 0.298, p = 0.0001). A significant number of children (52.7%) with VDD had low VDBP (p = 0.015). and despite adequate sun exposure, 43% of children showed VDD and 56.6% had low VDPB levels. The low VDBP levels largely explain low 25OHD levels without necessarily implying VDD. It may add a new dimension for better understanding of widespread VDD among under-five children. It thus, points towards the need for redefining cut offs and complete evaluation of vitamin D status among under-fives including VDBP.

Estimation of plasma levels of bisphenol-A & phthalates in fertile & infertile women by gas chromatography-mass spectrometry.

BACKGROUND & OBJECTIVES: Bisphenol-A (BPA) and phthalates are utilized widely in consumer products. Due to their ubiquitous presence in the environment, a concern is expressed worldwide about their possible effect on human reproductive health. This study was conducted to compare the internal exposure of BPA and phthalates (using their metabolites as biomarkers) in plasma samples of infertile and fertile women. METHODS: A sensitive gas chromatographic-mass spectrometric (GC-MS) method was developed to simultaneously quantify BPA and four phthalate monoester metabolites [namely mono-methyl phthalate (MMP), mono-benzyl phthalate (MBzP), mono-2-ethylhexyl phthalate (MEHP) and mono-(2-ethyl-5-hydroxyhexyl) phthalate (MEHHP)] in human plasma. The method was validated using charcoal-stripped human plasma. Activated charcoal was also utilized to reduce contamination from reagents. The method was designed to account for and/or eliminate background contamination from all sources. RESULTS: The limit of quantification for the method was 5 ng/ml for MMP and MBzP, while 1 ng/ml for BPA, MEHP and MEHHP, respectively. The precision and accuracy were well within the acceptable range. BPA was detectable in 77 per cent of plasma samples of infertile women and 29 per cent of fertile women. All the four phthalate metabolites were detected in plasma samples of both fertile and infertile women. INTERPRETATION & CONCLUSIONS: A GC-MS was developed and validated to estimate the BPA and four phthalate monoester metabolites in human plasma. It was utilised to analyse the plasma samples from fertile and infertile women. The infertile women showed significantly higher plasma concentrations of MBzP, BPA and MEHHP as compared to fertile women. The levels of MMP and MEHP were not significantly different between the two groups. Further studies need to be done to confirm these preliminary findings.

Impact of training on awareness and Knowledge of Birth Defects among Community Health Workers in tribal district of Maharashtra, India.

OBJECTIVE: Early identification, referrals and timely treatment is crucial to improve the outcome of Birth Defects (BDs). The role of Community Health Workers (CHWs) in India is largely fulfilled by Accredited Social Health Activists (ASHAs) who can play an important role in community-based reporting and referrals of BDs in newborn. In the study area, ASHAs have been previously trained for identification of BDs under Rashtriya Bal Swasthya Karyakram (RBSK); however, reporting through them was found to be sub-optimal. METHODS: To strengthen the community based reporting of BDs through ASHAs, audio visual based training was provided to 1225 ASHAs in 6 tribal blocks of Palghar district in Maharashtra, India. The change in knowledge about BDs before and after training among 1023 participants was analyzed using paired sample t test & McNemar test. RESULTS: Findings reveal a significant increase in the knowledge of participants with regards to prevention, risk factors and identification of BDs after intervention as compared to before intervention. DISCUSSION: The study suggests that audio-visual based refresher training increased knowledge of ASHAs with respect to identification, prevention and risk factors of BDs which may eventually improve reporting and referrals of BDs at community level.

Relevance of augmented kisspeptin signaling through H364 KISS1R in central precocious puberty.

Understanding the pathophysiology of idiopathic central precocious puberty (ICPP) is essential, in view of its consequences on reproductive health and metabolic disorders in later life. Towards this, estimation of circulating levels of the neuropeptides, viz; Kisspeptin (Kp-10), Neurokinin B (NKB) and Neuropeptide Y (NPY), acting upstream to Gonadotropin-Releasing Hormone (GnRH), has shown promise. Insights can also be gained from functional studies on genetic variations implicated in ICPP. This study investigated the pathophysiology of ICPP in a girl by exploring the therapeutic relevance of the circulating levels of Kp-10, NKB, NPY and characterizing the nonsynonymous KISS1R variant, L364H, that she harbours, in a homozygous condition. Plasma levels of Kp-10, NKB and NPY before and after GnRH analog (GnRHa) treatment, were determined by ELISA. It was observed that GnRHa treatment resulted in suppression of circulating levels of Kp-10, NKB and NPY. Further, the H364 variant in KISS1R was generated by site directed mutagenesis. Post transient transfection of either L364 or H364 KISS1R variant in CHO cells, receptor expression was ascertained by western blotting, indirect immunofluorescence and flow cytometry. Kp-10 stimulated signalling response was also determined by phospho-ERK and inositol phosphate production. Structure-function studies revealed that, although the receptor expression in H364 KISS1R was comparable to L364 KISS1R, there was an enhanced signalling response through this variant at high doses of Kp-10. Thus, elevated levels of Kp-10, acting through H364 KISS1R, contributed to the manifestation of ICPP, providing further evidence that dysregulation of Kp-10/KISS1R axis impacts the onset of puberty.

Latent TB in Indian pediatric population: An update on evidence gaps and research needs.

The main aim of this article is to review various studies conducted in relation to diagnosis, treatment and management of Latent TB Infection (LTBI) in under-five children, thus highlighting research gaps and further scope of improvements with respect to Indian context. The methodology involved literature review of various online review articles and research papers along with current published guidelines for LTBI management by World Health Organization (WHO) and National tuberculosis Elimination Program (NTEP). There is a dearth of statistically significant data regarding prevalence of LTBI among under-five children in India. LTBI prevalence in Indian adults has been reported between 21 and 48%. The exact prevalence of pediatric LTBI in India is still not clear, however, as per few studies, the LTBI prevalence ranges around 40% and 22% in adolescent followed by under-5 population. Studies to fill in the research gap of scarcity of prevalence data, regarding pediatric LTBI in high TB burden areas of India, is a pivotal step to curb the global pandemic of TB disease. There is a massive undervaluation of the true burden of childhood LTBI as the influence of environmental reservoir in childhood LTBI and TB are not accounted for in pediatric LTBI regimens. Also, there is no substantiate amount of data that highlights the other aspects of LTBI in pediatric population, like awareness regarding LTBI condition and other physiological adverse effects of LTBI in pediatric population, which have been often observed in under-five children suffering from LTBI.

Dysregulated serum and seminal plasma levels of surfactant protein D and MCP-1 in men with genital tract infection/inflammation.

PROBLEM: Surfactant protein D (SP-D), a multimeric collectin expressed by testicular mucosal epithelia and is positively regulated by testosterone. It exerts antimicrobial effects, modulates inflammation and rescued spermatogenesis in a murine model. Various cytokines and chemokines, including MCP-1, play a key role in regulating the inflammation in rat and human testis. The study aimed to investigate the role of SP-D and involvement of chemokines and cytokines in the male infertility associated with urogenital infections or inflammation. METHOD OF STUDY: The cross-sectional study evaluated levels of SP-D, testosterone, estradiol and the cytokines/chemokines including MCP-1 in the serum and semen samples of fertile and infertile Indian men with and without urogenital infections/inflammation (n = 76). RESULTS: Both fertile and infertile males with urogenital infection/inflammation had significantly lower levels of SP-D and higher levels of the chemokine, Monocyte chemoattractant protein 1 (MCP-1) in the serum and seminal plasma. Seminal plasma of these males exhibited significantly higher proportion of proteolytically degraded forms of SP-D. The serum SP-D levels positively correlated with testosterone/estradiol (TE) ratio. There was no significant correlation between the SP-D levels in seminal plasma and sperm count/motility. With a significant area under the Receiver Operating Characteristic curves, the serum and seminal plasma SP-D levels exhibited significant potential to predict infertility with high sensitivity and specificity in men with genital infections/inflammation. CONCLUSIONS: The circulating and seminal plasma SP-D levels were decreased in men with urogenital infection and inflammation. This could be due to their engagement at the site of infection, dysregulated expression owing to the altered hormonal profile and increased proteolytic degradation.

Yoga Intervention Improves the Metabolic Parameters and Quality of Life among Infertile Women with Polycystic Ovary Syndrome in Indian Population.

Background: The heterogenic manifestations of polycystic ovarian syndrome have led to various treatment approaches that include improving hormonal imbalance, weight management, and improving quality of life (QoL). Yoga therapy being a versatile treatment approach benefits physical and mental well-being and can be recommended to women with polycystic ovary syndrome (PCOS). Objective: The objective of this study was to study the effect of structured yoga intervention on anthropometric, metabolic, hormonal, biochemical, ovarian morphology, and infertility-related QoL parameters among infertile women with PCOS. Settings and Design: A prospective, controlled before and after study was conducted at a Multidisciplinary PCOS Clinic in Mumbai, Maharashtra, India. Methodology: Infertile women with PCOS (26 participants in each group which includes intervention and control arm) seeking treatment for infertility at the Multidisciplinary PCOS Clinic at National Institute for Research in Reproductive and Child Health. The intervention group received 90 min of structured yoga intervention for 3 months. Statistical Analysis: The median change in parameters between baseline and after 12 weeks of intervention was analyzed using IBM SPSS software, version 26 to perform descriptive analyses and Wilcoxon test to analyze pre- and postintervention parameters in the intervention and control group. Results: There was a significant difference in the weight, basal metabolic rate, postglucose insulin, anti-Müllerian hormone, cholesterol, high-density lipoprotein, low-density lipoprotein, serum glutamic pyruvic transaminase, ultrasound parameters such as stromal thickness, follicle number per ovary, and QoL in infertility domain in the intervention group compared to the control group. Within 1 year of initiation of the study, 13 participants became pregnant in the yoga intervention group as compared to 7 participants in the control group. Conclusion: The metabolic comorbidities of PCOS have adverse effects on the QoL and pregnancy outcome among infertile women with PCOS. This pilot study demonstrated that a 12-week yoga intervention brought overall improvement in anthropometric, hormonal, biochemical, ovarian morphology, and infertility-related QoL parameters compared to the control group. Integration of yoga in infertility management will help to improve the QoL and to optimize prepregnancy metabolic parameters among infertile women with PCOS.

Challenges in Accessing and Delivering Maternal and Child Health Services during the COVID-19 Pandemic: A Cross-Sectional Rapid Survey from Six States of India.

BACKGROUND/OBJECTIVES: Globally, the COVID-19 pandemic and its prevention and control policies have impacted maternal and child health (MCH) services. This study documents the challenges faced by patients in accessing MCH services, and the experiences of health care providers in delivering those services during the COVID-19 outbreak, explicitly focusing on the lockdown period in India. METHODS: A cross-sectional study (rapid survey) was conducted in 18 districts from 6 states of India during March to June, 2020. The sample size included 540 MCH patients, 18 gynaecologists, 18 paediatricians, 18 district immunisation officers and 108 frontline health workers. Bivariate analysis and multivariable analysis were used to assess the association between sociodemographic characteristics, and challenges faced by the patients. RESULTS: More than one-third of patients (n = 212; 39%) reported that accessing MCH services was a challenge during the lockdown period, with major challenges being transportation-related difficulties (n = 99; 46%) unavailability of hospital-based services (n = 54; 23%) and interrupted outreach health services (n = 39; 18.4%). The supply-side challenges mainly included lack of infrastructural preparedness for outbreak situations, and a shortage of human resources. CONCLUSIONS/RECOMMENDATIONS: A holistic approach is required that focuses on both preparedness and response to the outbreak, as well reassignment and reinforcement of health care professionals to continue catering to and maintaining essential MCH services during the pandemic.

Association of OPG and RANKL gene polymorphisms with bone mineral density in Indian women.

Osteoprotegerin (OPG) and receptor activator of the NF-kB ligand (RANKL) are key players in bone remodelling. Reports show that OPG and RANKL gene polymorphisms are associated with osteoporosis and fracture risk. The aim of this study was to examine the influence of 5 single nucleotide polymorphisms (SNPs) in OPG and RANKL gene on bone mineral density (BMD) in Indian women. The study included 374 healthy Indian women. Kompetitive Allele Specific PCR (KASP) was used for genotyping. There was a significant difference in the BMD at spine between genotypes of OPG rs2073618 (CC: 0.988 ± 0.167 CG: 1.023 ± 0.17 GG: 1.053 ± 0.155; p = 0.039) which was lost upon adjustment for age and BMI (p = 0.087). Multiple linear regression revealed that genotypes of OPG rs2073618 (ß = 0.098; p = 0.027) and rs3102735 (ß = 0.092; p = 0.038) are predictors of BMD at spine in Indian women. We did not observe any association of SNPs in RANKL gene with BMD. Thus, SNPs rs2073618 and rs3102735 in OPG gene may influence BMD at spine in Indian women.

Proteomic and genetic dissection of testis-specific histone 2B in infertile men reveals its contribution to meiosis and sperm motility.

OBJECTIVE: To investigate testis-specific histone 2B (TSH2B) and its gene anomalies in infertile men. DESIGN: Case-control study. SETTING: Basic science laboratory. PATIENT(S): Fertile and infertile men. INTERVENTION(S): Not applicable. MAIN OUTCOME MEASURE(S): The histone and protamine status of sperm was studied by aniline blue and chromomycin A3 staining, respectively. Testis-specific histone 2B, total H2B, and phosphorylated TSH2B (pTSH2B) were estimated by Western blot analysis. The frequency of genetic polymorphisms and rare variants in H2BC1 was studied by Sanger sequencing. Phosphosites on TSH2B in sperm were identified by reverse-phase high-performance liquid chromatography purification of TSH2B followed by mass spectrometric analysis. RESULT(S): Aniline blue and chromomycin A3 staining revealed significantly higher histone retention and low protamine in sperm of infertile men. Sperm TSH2B and total H2B levels were significantly lower in oligozoospermic and oligoasthenozoospermic men (in both groups). The TSH2B levels were comparable in asthenozoospermic men; however, the pTSH2B level was significantly low. The H2BC1 gene sequencing identified 6 variants, of which 2 are rare variants (rs368672899 and rs544942090) and 4 (rs4711096, rs4712959, rs4712960 and rs4712961) are single nucleotide polymorphisms. Minor allele frequency of 5'-untranslated region variant rs4711096 was significantly lower in infertile men (OR = 0.65). The rare nonsynonymous variant, rs368672899, p.Ser5Pro was seen in 1 oligoasthenoteratozoospermic individual. Interestingly, mass spectrometric analysis identified a site on TSH2B to bear a phosphate group in the sperm of fertile men. CONCLUSION(S): Our study reveals a defect in the replacement of somatic histones with testis-specific variants in infertile men. Chromatin compaction positively correlates with sperm motility, which is suggestive of its utility in diagnostic semen analysis of infertile individuals. Our observations with TSH2B and its cognate gene in sperm of infertile men indicate an essential role for TSH2B in meiosis and its phosphorylation in sperm motility, respectively.

Protocol for a prospective, hospital-based registry of pregnant women with SARS-CoV-2 infection in India: PregCovid Registry study.

INTRODUCTION: Pregnant women are at increased risk of contracting COVID-19 due to several factors and therefore require special attention. However, the consequences of the COVID-19 pandemic on pregnant women and their newborns remain uncharted. The PregCovid registry aims to document the impact of SARS-CoV-2 infection on pregnant, postpartum women and their newborns. The aim of the registry is also to determine mother-to-child transmission of SARS-CoV-2 infection in India. METHODS AND ANALYSIS: PregCovid is a hospital-based registry for capturing information of pregnant, postpartum women with COVID-19 and their newborns in India. Medical case records of pregnant and postpartum women with a laboratory-confirmed diagnosis of COVID-19 will be captured in real-time using an online electronic patient record software. The data analysis will be carried out for symptoms, the severity of COVID-19, pregnancy complications, maternal morbidity and mortality, neonatal complications, mother-to-child transmission, etc. Data analysis will be carried out for different waves of the COVID-19 pandemic for rapid response and developing strategies well in advance to manage pregnant women infected with SARS-CoV-2. The evidence generated from the registry will be regularly shared with the appropriate authorities for policy decisions. Thus, the registry data may be useful for planning the strategies for better management of pregnant women with COVID-19. ETHICS AND DISSEMINATION: The study has been approved by the Institutional Ethics Committees of all the participating study sites under the Medical Education and Drugs Department, Government of Maharashtra, Topiwala National Medical College & BYL Nair Charitable Hospital, Mumbai and ICMR-National Institute for Research in Reproductive and Child Health, Mumbai, India.
