RESUMO

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.

RESUMO

PURPOSE: The vaginal microbiome contributes significantly to women's reproductive health and fluctuates due to various physiological and pathological factors. The study's objective is to map the vaginal microbiome of non-pregnant women and evaluate variations based on various potential factors influencing vaginal milieu. METHODS: Fifty-two sexually active, non-pregnant women between 18 and 45 years were recruited from a community clinic and clinical history was recorded. Vaginal swabs were collected to assess the vaginal microbiome by sequencing the V3-V4 region of the 16S rRNA using the Illumina HiSeq platform, followed by data analysis with QIIME 2. Vaginal milieu was assessed by Nugent score and profiling cytokines in the cervico-vaginal lavage. RESULTS: Lactobacillus iners (34.3%) were the most abundant species in all women. Significant changes in abundance of genera (Lactobacillus, Prevotella and Anaerococcus), expression of pro-inflammatory cytokine IFN-γ and changes in alpha and beta diversity was observed in women having asymptomatic bacterial vaginosis (BV). Differences in beta diversity were seen between healthy women and women exhibiting presence of Candida spp. Variations in the abundance of genera (Lactobacillus, Bifidobacterium, Porphyromonas) were observed in women who had delivery less than twelve months back, probably as more of these women (50%, 53.7%) had higher abnormal Nugent score. CONCLUSION: Lactobacillus iners was the most prevalent vaginal species in women from a Mumbai community clinic. Maximum variations in the vaginal microbiome characterized by a perturbation of the Lactobacillus predominant vaginal microbiota are seen in those women who have asymptomatic BV and childbirth within last twelve months.

RESUMO

Background: Polycystic ovary syndrome (PCOS) is one of the most common endocrine disorder having most impact on women of reproductive age group, affecting their quality of life (HRQOL) and psychological well-being. Objective: This paper aims to determine QOL among women affected with PCOS attending a multidisciplinary clinic using PCOSQ tool and its association with socio-economic status, phenotypes, anxiety, depression and metabolic comorbidities and evaluate the coping strategies adapted by these women. Design: Retrospective study. Setting: Integrated multidisciplinary PCOS clinic. Patients: Two hundred and nine women diagnosed with PCOS as per Rotterdam criteria. Results: Infertility was an important condition for reduced HRQOL and psychological morbidity across all socio-economic status and phenotypes. The poor psychological status and obesity were identified as determinants of HRQOL among women affected with PCOS. Those who suffered from anxiety, depression and showed lower HRQOL used emotional maladaptive coping strategies. Conclusion: Results reveal that HRQOL of PCOS women is worsened in the presence of comorbidities. Maladaptive and disengagement coping strategies used by women may worsen their psychological status. Holistic assessment of comorbidities and its management can help improve HROL of affected women. Personalised counselling based on the assessment of coping strategies used by women could empower women to cope better with PCOS.

RESUMO

BACKGROUND: The COVID-19 pandemic and the associated social restrictions may have disrupted the provision of essential services, including family planning (FP) and contraceptive services. This protocol is adapted from a generic study protocol titled "Health systems analysis and evaluations of the barriers to availability and readiness of sexual and reproductive health services in COVID-19 affected areas," conducted by the World Health Organization (WHO) Department of Reproductive Health and Research. OBJECTIVE: This study aims to assess the availability and use of FP and contraceptive services in primary health facilities during and after the COVID-19 pandemic; assess the risk perceptions of COVID-19 stigma, barriers to access, and quality of services from clients' and providers' perspectives in the COVID-19-affected areas; and assess the postpandemic recovery of the facilities in the provision of FP and contraceptive services. METHODS: In-depth interviews will be conducted with clients-women in the reproductive age group and their male partners who visit the selected health facilities for FP and contraceptive services-and health providers (the most knowledgeable person on FP and contraceptive service provision) at the selected health facilities. Focus group discussions will be conducted with clients at the selected health facilities and in the community. The in-depth interviews and focus group discussions will help to understand clients' and health service providers' perspectives of FP and contraceptive service availability and readiness in COVID-19-affected areas. A cross-sectional health facility assessment will be conducted in all the selected health facilities to determine the health facility infrastructure's ability and readiness to provide FP and contraceptive services and to capture the trends in FP and contraceptive services available during the COVID-19 pandemic. Scientific approval for this study is obtained from the WHO Research Project Review Panel, and the WHO Ethics Review Committee has given ethical approval in the 3 countries. RESULTS: Using a standardized research protocol will ensure that the results from this study can be compared across regions and countries. The study was funded in March 2021. It received ethics approval from the WHO Ethics Review Committee in February 2022. We completed data collection in September 2022. We plan to complete the data analysis by March 2023. We plan to publish the study results by Summer 2023. CONCLUSIONS: The findings from this study will provide a better understanding of the impact of the COVID-19 pandemic on FP and contraceptive services at the facility level, which will help policy makers and health managers develop and strengthen FP policies and services in health facilities to be more responsive to community needs.

RESUMO

OBJECTIVE: To study the genome wide alterations in sperm DNA methylation in male partners of idiopathic recurrent pregnancy loss (iRPL) cases and note regions as potential diagnostic markers. DESIGN: Case-control study and methylome analysis of human sperm. SETTING: Obstetrics and Gynaecology clinics. PATIENT(S): Control group consists of apparently healthy fertile men having fathered a child within the last 2 years (n = 39); and case group consists of male partners of iRPL cases having ≥2 consecutive 1st trimester pregnancy losses (n = 47). INTERVENTION(S): None. MAIN OUTCOME MEASURE(S): Sperm DNA samples of controls and cases were selected for whole genome bisulfite sequencing analysis based on the previously set thresholds of global methylation levels and methylation levels of imprinted genes (KvDMR and ZAC). Whole genome bisulfite sequencing of selected sperm genomic DNA was performed to identify differentially methylated CpG sites of iRPL cases compared with fertile controls. Pathway analysis of all the differentially methylated genes was done by Database for Annotation, Visualization, and Integrated Discovery annotation tool and Kyoto Encyclopedia of Genes and Genomes tool. Differentially methylated CpGs within genes relevant to embryo and placenta development were selected to further validate their methylation levels in study population by pyrosequencing. RESULT(S): A total of 9497 differentially methylated CpGs with highest enrichment in intronic regions were obtained. In addition, 5352 differentially methylated regions and 2087 differentially methylated genes were noted. Signaling pathways involved in development were enriched on pathway analysis. Select CpGs within genes PPARG, KCNQ1, SETD2, and MAP3K4 showed distinct hypomethylated subpopulations within iRPL study population. CONCLUSION(S): Our study highlights the altered methylation landscape of iRPL sperm, and their possible implications in pathways of embryo and placental development. The CpG sites that are hypomethylated specifically in sperm of iRPL subpopulation can be further assessed as predictive biomarkers.

RESUMO

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.

RESUMO

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. Measurement of vaginal cytokines was done for various interleukins including IL-1ß, IL-6, IL-8, IL-10, IL-12/IL23p40, IL-17A, tumour necrosis factor alpha (TNF-α) and interferon gamma (IFN-γ) by ProcartaPlex™ Multiplex Immunoassay. Women having vaginal Candida infection had increased concentration of IL-1ß (p=.01), IL-6 (p=.007), IL-8 (p=.327), IL-12/IL23p40 (p=.049) and IFN-γ (p=.125). The results of our study suggest that evaluation of these cytokines could be explored as an additional measure to determine host inflammatory response in women having asymptomatic vaginal candidiasis.Impact StatementWhat is already known on this subject? Studies assessing the vaginal cytokine profile to assess the vaginal milieu in various cohorts such as post-menopausal women, pregnant women, women with history of preterm birth, CIN and scheduled IVF cycle are being undertaken. Variable cytokine response has been reported in literature in women with symptomatic bacterial vaginosis and Candida infection. However, much less is known about vaginal cytokine profile in asymptomatic infection.What do the results of this study add? The results of the study show increased concentration of the pro-inflammatory cytokines IL-1ß, IL-6 IL-8, IL-12/IL23p40 and interferon gamma (IFN-γ) in women having asymptomatic Candida, vaginal leucocytosis and raised vaginal pH.What are the implications of these findings for clinical practice and/or further research? Evaluation of vaginal cytokine profile (IL-1ß, IL-6 IL-8, IL-1ß, IL-12/IL23p40 and IFN-γ) could be explored as an additional measure to determine inflammation in asymptomatic women. Vaginal cytokines (IL-1ß, IL-6 IL-8, IL-1ß, IL-12/IL23p40 and IFN-γ) could be used further for development of a point of care test.

RESUMO

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.

RESUMO

Background & objectives: Non-communicable diseases (NCDs) and cancers of breast, oral cavity and cervix contribute to around 5.87 million (60%) deaths in India. Despite this, there is limited evidence on preparedness of the tribal health system in mitigating these conditions. This mixed-methods study aimed at identifying enablers and challenges using a multistakeholder approach for the screening of NCDs and common cancers in a tribal block of Maharashtra, India. Methods: This study was conducted in a tribal community of Dahanu taluka in Palghar district of Maharashtra. A total of nine focus group discussions (FGDs) among tribal women and accredited social health activists (ASHAs), 13 key informant interviews (KIIs) among auxiliary nurse midwives (ANMs) and community health officers (CHO) and facility surveys of five public health facilities were conducted. The FGDs and KIIs were conducted using guides, recorded digitally, transcribed, analyzed and triangulated to identify emerging themes. Results: The tribal women had limited knowledge about NCDs and common cancers. Paucity of health facilities, out-of-pocket expenditure, misconceptions, belief on traditional healers and inability to prioritize health were identified as major challenges. The ASHAs were recognized as a key connecting link between health system and community while provision of culturally appropriate IEC materials and adequate training were recognized as critical enablers by healthcare providers in implementing screening for NCDs and common cancers. Interpretation & conclusions: The study recommends incorporating socioculturally relevant strategies in the tribal population and strengthening health facilities in terms of infrastructure and training with involvement of ASHAs for successful implementation of the National Programme for Prevention and Control of Cancer, Diabetes, Cardiovascular Diseases and Stroke (NPCDCS) through health and wellness centres.

RESUMO

Despite adequate treatment of reproductive tract infection, there is persistence of symptoms in some patients. This raises the possibility of existence of other silent microbes with pathogenic potential. Apart from the common sexually transmitted organisms such as Chlamydia trachomatis and Neisseria gonorrhoeae, there are other silent and emerging pathogens, like genital mycoplasma, which have been associated with cervicitis, pelvic inflammatory disease, infertility, and pregnancy-related complications in women. Although these organisms were identified decades ago, they are still overlooked or ignored. There is a need to understand the role played by these organisms in Asian populations and their susceptibility to the standard line of treatment. Data on genital mycoplasma infections in Indian women is heterogeneous, with limited evidence of pathogenicity. Although known for their wide spectrum of reproductive morbidities in western counterparts, these microorganisms are yet to gain the attention of Indian clinicians and microbiologists. There is paucity of adequate information in India regarding these infections, so Indian literature was compiled to get an overview of these pathogens, their association with reproductive morbidities, and their response to treatment. Thus, there is a need to explore genital mycoplasma infections in Indian women, especially in the arena of antimicrobial resistance among genital mycoplasma, which has the potential to become a major problem. A literature search with keywords focusing on "genital mycoplasma", "sexually transmitted infections India", "sexually transmitted mycoplasma", and "characteristic of mycoplasma" was carried out through computerized databases like PubMed, MEDLINE, Embase, and Google Scholar.

RESUMO

PURPOSE: The aim of the present work is the development of a simple mathematical model for the time course concentration profile of topically administered drugs in the anterior chamber aqueous humor and investigation of the effects of various model parameters on the aqueous humor concentration of lipophilic and hydrophilic drugs. METHOD: A simple pharmacokinetic model for the transient drug transport in the anterior segment has been developed by using the conservation of mass in the precorneal tear film, Fick's law of diffusion and Michaelis-Menten kinetics of drug metabolism in cornea, and the conservation of mass in the anterior chamber. An analytical solution describing the drug concentration in the anterior chamber has been obtained. RESULT: The model predicts that an increase in the drug metabolic (consumption) rate in the corneal epithelium reduces the drug concentration in the anterior chamber for both lipophilic and hydrophilic molecules. A decrease in the clearance rate and distribution volume of the drug in the anterior chamber raises the aqueous humor concentration significantly. It is also observed that decay rate of drug concentration in the anterior chamber is higher for lipophilic molecules than that for hydrophilic molecules. CONCLUSION: The bioavailability of drugs applied topically to the eye may be improved by a rise in the precorneal tear volume, diffusion coefficient in corneal epithelium and distribution coefficient across the endothelium anterior chamber interface, and by reducing the drug metabolism, drug clearance rate and distribution volume in anterior chamber.
