Impact of training on awareness and Knowledge of Birth Defects among Community Health Workers in tribal district of Maharashtra, India. Birth Defects Res 2024; 116:e2264. [PMID: 37933599 DOI: 10.1002/bdr2.2264] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/24/2023] [Revised: 09/06/2023] [Accepted: 10/16/2023] [Indexed: 11/08/2023]
Abstract
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.

Challenges in screening for sickle cell disease among newborns from the tribal region of Palghar, Maharashtra during the COVID-19 pandemic. Indian J Med Res 2023; 158:378-383. [PMID: 38006343 DOI: 10.4103/ijmr.ijmr_3220_21] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/03/2021] [Indexed: 11/27/2023] Open
Abstract
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.

Latent TB in Indian pediatric population: An update on evidence gaps and research needs. Indian J Tuberc 2023; 70 Suppl 1:S8-S13. [PMID: 38110266 DOI: 10.1016/j.ijtb.2023.04.008] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/16/2021] [Revised: 03/31/2023] [Accepted: 04/05/2023] [Indexed: 12/20/2023]
Abstract
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. Am J Reprod Immunol 2023; 89:e13588. [PMID: 35771685 DOI: 10.1111/aji.13588] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/08/2022] [Revised: 05/06/2022] [Accepted: 06/13/2022] [Indexed: 02/01/2023] Open
Abstract
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.

INTERNATIONAL JOURNAL OF ENVIRONMENTAL RESEARCH AND PUBLIC HEALTH 2023; 20:1538. [PMID: 36674296 PMCID: PMC9865999 DOI: 10.3390/ijerph20021538] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Figures] [Subscribe] [Scholar Register] [Received: 09/16/2022] [Accepted: 11/24/2022] [Indexed: 06/17/2023]
Abstract
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.

Proteomic and genetic dissection of testis-specific histone 2B in infertile men reveals its contribution to meiosis and sperm motility. F&S SCIENCE 2022; 3:322-330. [PMID: 35840050 DOI: 10.1016/j.xfss.2022.07.003] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 05/19/2022] [Revised: 07/07/2022] [Accepted: 07/07/2022] [Indexed: 06/15/2023]
Abstract
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.

Abstract
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 (β = 0.098; p = 0.027) and rs3102735 (β = 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.

Abstract
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.

Abstract
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.

Indian J Med Microbiol 2021; 40:144-146. [PMID: 34772538 DOI: 10.1016/j.ijmmb.2021.10.003] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/16/2021] [Revised: 09/22/2021] [Accepted: 10/07/2021] [Indexed: 11/27/2022]
Abstract
Cervicitis is an inflammatory condition of cervix, when presented along with vaginal discharge; it is termed as cervico-vaginitis. These can be infective, hence important to diagnose due to risk of spreading to upper genital tract. This cross-sectional study was undertaken to evaluate the microbiological spectrum in cervicitis or cervico-vaginitis among 100 sexually active women by Gram stain and Multiplex Real time polymerase chain reaction. Bacterial vaginosis 21(21%) was the most common RTI. Among STIs, genital mycoplasmas were the predominant infections hence further research is required to understand their pathogenesis.

Abstract
BACKGROUND SARS-CoV-2 has infected a large number of pregnant women. OBJECTIVE To compare clinical, perinatal outcomes of women with COVID-19 from high-income countries (HICs) and low- to middle-income countries (LMICs). SEARCH STRATEGY Online databases were searched. SELECTION CRITERIA Original studies on pregnant women with COVID-19 were included. DATA COLLECTION AND ANALYSIS Information on clinical presentation, co-morbidities, pregnancy outcomes, neonatal outcomes, and SARS-CoV-2 infection in neonates was extracted. MAIN RESULTS The pooled estimate of SARS-CoV-2 positive neonates is 3.7%. Symptomatic presentations are less common in LMICs compared to HICs (odds ratio [OR] 0.38). Diabetes (OR 0.5), hypertension (OR 0.5), and asthma (OR 0.14) are commonly reported from HICs; hypothyroidism (OR 2.2), anemia (OR 3.2), and co-infections (OR 6.0) are commonly reported in LMICs. The overall risk of adverse pregnancy outcomes is higher in LMICs compared to HICs (OR 2.4). Abortion (OR 6.2), stillbirths (OR 2.0), and maternal death (OR 7.8) are more common in LMICs. Preterm births and premature rupture of membranes are comparable in both groups. Neonatal deaths (OR 3.7), pneumonia (OR 7.5), and neonatal SARS-CoV-2 infection (OR 1.8) are commonly reported in LMICs. CONCLUSIONS In LMICs, pregnant women and neonates are more vulnerable to adverse outcomes due to COVID-19. PROSPERO registration no: CRD42020198743.

Abstract
A community-based study was undertaken in an urban slum in Mumbai, between October, 2015 and September, 2017 among 426 healthy children (aged 1-5 years) to assess prevalence of vitamin D deficiency (VDD) and its determinants. VDD was classified as 25(OH)D <20 ng/mL. The prevalence of VDD was 76.8% (n=327), and sun-exposure, male sex, and calcium and vitamin D supplementations during infancy were important determinants. Routine supplementation with vitamin D in infancy is likely to reduce the occurrence of VDD in children.

Abstract
Osteoporosis is one of the chronic and often neglected bone diseases in aging postmenopausal women that affect the quality of life. Studies on ovariectomized mice models indicated the reciprocal role of Th17 cells and Treg cells in the aetiology of osteoporosis. While Th17 cells promote osteoclastogenesis, Treg cells exhibit anti-osteoclastogenic activity. This exploratory study aimed to determine the difference in the frequency of these T-cell subtypes in pre-and postmenopausal women and to examine their association with BMD. In our study, the frequency of Treg cells, analyzed by flow cytometry, did not differ between pre-and postmenopausal women. However, plasma levels of IL-10 along with IL-10+CD4+T cells were higher in post- compared to premenopausal women. The frequency of Th17 cells was higher in postmenopausal women irrespective of their BMD, however, only postmenopausal women with low BMD had elevated IL-17 levels and their T-scores were associated with Th17 frequency. Collectively, the results suggest that estrogen insufficiency in postmenopausal women may lead to increased Th17 cell frequency and elevated IL-17 levels which are associated with low BMD. This study highlights, Th17 cells and IL-17 as key players in the pathogenesis of osteoporosis and they can be the potential targets for immunotherapy in the treatment of osteoporosis.

Abstract
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.

Abstract
BACKGROUND Biological relevance of the major testis specific histone H2B variant (TH2B) in sperm is not fully understood. Studies in TH2A/TH2B double knockout male mice indicate its role in chromatin compaction and male fertility. Additionally, the presence of TH2B and TH2A reportedly generates more dynamic nucleosomes, leading to an open chromatin structure characteristic of transcriptionally active genome. Given that mature human sperm are transcriptionally and translationally inactive, the presence of TH2B in mature sperm is intriguing. To address its role in sperm, we investigated the genome-wide localization of TH2B in sperm of fertile men. RESULTS We have identified the genomic loci associated with TH2B in fertile human sperm by ChIP-seq analysis. Bioinformatic analysis revealed ~ 5% sperm genome and 5527 genes to be associated with TH2B. Out of these 105 (1.9%) and 144 (2.6%) genes showed direct involvement in sperm function and early embryogenesis, respectively. Chromosome wide analysis for TH2B distribution indicated its least distribution on X and Y chromosomes and varied distribution on autosomes. TH2B showed relatively higher percentage of gene association on chromosome 4, 18, 3 and 2. TH2B enrichment was more in promoter and gene body region. Gene Ontology (GO) analysis revealed signal transduction and associated kinase activity as the most enriched biological and molecular function, respectively. We also observed the enrichment of TH2B at developmentally important loci, such as HOXA and HOXD and on genes required for normal sperm function, few of which were validated by ChIP-qPCR. The relative expression of these genes was altered in particular subgroup of infertile men showing abnormal chromatin packaging. Chromatin compaction positively correlated with sperm- motility, concentration, viability and with transcript levels of PRKAG2 and CATSPER B. CONCLUSION ChIP-seq analysis of TH2B revealed a putative role of TH2B in sperm function and embryo development. Altered expression of TH2B associated genes in infertile individuals with sperm chromatin compaction defects indicates involvement of TH2B in transcriptional regulation of these genes in post meiotic male germ cells. This altered transcriptome may be a consequence or cause of abnormal nuclear remodeling during spermiogenesis.

Abstract
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.

Effect of Vitamin D Levels on Bone Remodeling in Healthy Women. Int J Endocrinol Metab 2020; 18:e100656. [PMID: 32636886 PMCID: PMC7322670 DOI: 10.5812/ijem.100656] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/31/2019] [Revised: 03/26/2020] [Accepted: 03/30/2020] [Indexed: 02/03/2023] Open
Abstract
BACKGROUND Vitamin D deficiency is prevalent among Indian women. Subclinical vitamin D deficiency is a significant risk factor for osteopenia and fractures. However, its effect on bone metabolism and bone mineral density (BMD) is still debatable. OBJECTIVES This study aimed to determine relationships of the vitamin D status with bone turnover markers, carboxy-terminal telopeptide of type-I collagen (CTX), N-terminal propeptide of type I procollagen (PINP), and BMD in healthy Indian women. METHODS In this cross-sectional study, we determined serum levels of 25-hydroxy vitamin D (25(OH)D), parathyroid hormone, serum CTX, and PINP using commercial ELISA kits in 310 healthy Indian women aged 25 - 65 years who underwent BMD measurements with DXA scan. RESULTS The prevalence of vitamin D deficiency was 53.87% and vitamin D insufficiency 31.29%. A direct correlation of BMD with vitamin D levels was not observed. PINP negatively correlated with vitamin D in both premenopausal (Spearman's r = -0.169, P < 0.05) and postmenopausal (Spearman's r = -0.241, P < 0.05) women. However, CTX positively correlated with vitamin D in both premenopausal (Spearman's r = 0.228, P < 0.01) and postmenopausal (Spearman's r = 0.244, P < 0.05) women. CONCLUSIONS Vitamin D deficiency is more prevalent in premenopausal women than in postmenopausal ones. Although vitamin D does not show any association with BMD, it affects bone remodeling, which is reflected by changes in the bone formation marker PINP and the bone resorption marker CTX.

Abstract
Ballet dancers have finite careers due to the demands placed upon their bodies throughout years of training, study, and performance. The average age a dancer retires is 34 due to persistent stress on their joints and injuries due to mechanical overload or overuse. Proper form is crucial to prevent injury. The aim of this study was to establish benchmarks for normal movement patterns among professional dancers. Ten professional ballerinas were studied. Reflective markers were placed on the pelvis, left and right anterior superior iliac spine (ASIS), and posterior iliac spine (PSIS) to evaluate motion during Barre movements: plié, grand battement, and développé. Pelvis flexion/extension, mediolateral rotation, and torsion were analyzed. These motions test different skills. The plié is a controlled coordinated motion using both legs. The grand battement and développé both require leg extension, one with a quick motion that creates momentum and one using controlled motion that requires strength. Each requires core and pelvis stability to perform accurately and with less injury. Dancers' motions were consistent. Maximum pelvis range of motion for the plié, grand battement, and développé were 8.0, 42, and 50 deg, respectively. This represents usable benchmarks with which other dancers may be compared, for example, those who are at different levels of training, injured, predisposed to injury, or recovering from injury. Early recognition of pathologic movement patterns could benefit professional and amateur dancers by helping to prevent injuries, and potentially improve the quality and length of their careers.

Abstract
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.

Abstract
BACKGROUND AND OBJECTIVES Vitamin D is a key determinant of bone health and calcium homeostasis in children. Vitamin D deficiency (VDD) in early years may have an effect on total bone mass and risk of osteoporosis. Despite widespread prevalence of VDD among children, there is limited information in under-five age group. The objectives of the current study were to estimate the community-based prevalence of VDD and to identify the factors associated with children aged 1-5 years. MATERIALS AND METHODS A community-based cross-sectional study was conducted among 201 apparently healthy children (aged 1-5 years) in an urban slum of the selected geographical area in Mumbai. VDD was defined as serum 25-hydroxy Vitamin D (25[OH]D) levels <20 ng/ml as per the US Endocrine society classification. RESULTS The prevalence of VDD was found to be 74.6% (95% of confidence interval [68.6-80.6]). It was significantly higher (P = 0.04) among children staying indoors (44.8%). 25(OH)D was negatively correlated with parathyroid hormone (PTH) ([r = -0.199, P = 0.005]) and Alkaline phosphatase ([r = -0.140, P = 0.05]). However, the increase in PTH was observed when 25(OH)D levels were <10 ng/ml unlike anticipated increase at <20 ng/ml. CONCLUSION The study revealed a high prevalence of VDD in 1-5 years age group. It was observed that the outdoor activities and sun exposure have a significant association with Vitamin D status. Majority of children had normal PTH levels despite VDD. The study endorses the importance of sun exposure and throws light on that fact that functional cutoffs for VDD may be lower in under-five children and also highlights the need of redefining cutoffs of Vitamin D among the Indian children.

Binding mitochondria to cryogel monoliths allows detection of proteins specifically released following permeability transition. Anal Biochem 2006; 348:209-21. [PMID: 16310157 DOI: 10.1016/j.ab.2005.08.032] [Citation(s) in RCA: 14] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/13/2005] [Revised: 08/12/2005] [Accepted: 08/19/2005] [Indexed: 10/25/2022]
Abstract
Following proapoptotic signals such as calcium-induced mitochondrial permeability transition or translocation of proapoptotic proteins, mitochondria induce cell death through release of apoptogenic proteins. The mechanism of release and the identity of the released proteins are currently debated. Earlier attempts at identification of the apoptogenic proteins have been hampered by a high nonspecific background. Our aim was to develop a novel method where background release was eliminated, allowing proteins specifically released from mitochondria following proapoptotic stimulation to be identified. Liver mitochondria were immobilized and washed on cryogel monoliths prior to induction of protein release (calcium or Bid/Bax). Immobilized mitochondria exhibited normal morphology and swelling response and retained respiratory activity. The released proteins were collected, concentrated, separated on polyacrylamide gels which were cut into pieces, trypsin-digested, and analyzed using liquid chromatography-tandem mass spectrometry. Control samples contained no protein, and stimulation with calcium and Bid/Bax resulted in identification of 68 and 82 proteins, respectively. We conclude that, in combination with the robust proteomic approach, immobilization on cryogel monoliths is a fruitful approach for studying specific protein release from isolated mitochondria. We propose that this method is a powerful tool to further characterize the role of mitochondria in cell death induction.
