Public Health System's Preparedness to Address Polycystic Ovarian Syndrome: A Rapid Assessment Survey of Health-care Providers in India.

BACKGROUND: Polycystic ovarian syndrome (PCOS) is one of the most common endocrine disorders largely affecting women of reproductive age group. OBJECTIVES: This study aimed to understand the Indian public health-care systems' preparedness in addressing PCOS. MATERIALS AND METHODS: A multicentric rapid assessment cross-sectional study was undertaken among 173 health-care providers serving across various public health-care facilities in India. This study was a component of a larger task force study that aimed to estimate the community-based prevalence of PCOS in India. Information on PCOS cases reported that knowledge about PCOS diagnosis, management practices, availability of diagnostic facilities, and drugs was explored. RESULTS: Irregular menstrual cycle was the most commonly reported PCOS symptom. Most of the health-care providers (HCPs) lacked correct knowledge about diagnostic criteria and investigation needed for the diagnosis of PCOS. Diagnostic facilities and drugs were inadequate. However, some facilities had access to investigations through public-private partnerships. Awareness programs on PCOS in the community were negligible, and PCOS cases were not documented. Training HCPs on PCOS along with the availability of specialists and strengthening diagnostic facilities were some major demands from the HCPs. CONCLUSION: Results suggest the need for training HCPs, strengthening infrastructure with good referral linkages, and adequate supply of drugs to help improve PCOS management at public health-care facilities in India. There is a need to develop national technical and operational guidelines to address PCOS using a multidisciplinary approach across all levels of care. Creating demand for services and advocating healthy lifestyles through community awareness can help early diagnosis and prevention of complications.

Aged garlic extract preserves beta-cell functioning via modulation of nuclear factor kappa-B (NF-κB)/Toll-like receptor (TLR)-4 and sarco endoplasmic reticulum calcium ATPase (SERCA)/Ca2+ in diabetes mellitus.

BACKGROUND: Peripheral insulin resistance and compromised insulin secretion from pancreatic ß-cells are significant factors and pathogenic hallmarks of diabetes mellitus (DM). NF-κß/TLR-4 and SERCA/Ca2+ pathways have been identified as potential pathways regulating insulin synthesis by preserving pancreatic ß-cell functioning. The current study aimed to evaluate the therapeutic effect of aged garlic extract (AGE) against DM in a streptozotocin (STZ)-induced rat model with particular emphasis on pancreatic ß-cell functioning. METHODS: AGE was characterized by gas chromatography-mass spectrometry (GC-MS), Fourier-transform infrared spectroscopy (FTIR), and scanning electron microscopy (SEM) to evaluate its physio-chemical characteristics followed by in-vitro anti-diabetic and antioxidant potential. This was followed by the induction of DM in laboratory animals for investigating the therapeutic action of AGE by evaluating the role of NF-κß/TLR-4 and the SERCA/Ca2+ pathway. The parameters assessed in the present experimental setup encompassed antioxidant parameters, metabolic indicators, insulin concentration, intracellular calcium levels, apoptotic markers (CCK-8 and Caspase Glo-8), and protein expression (P-62 and APACHE-II). RESULTS: AGE characterization by SEM, GC-MS, and X-ray diffraction (XRD) revealed the presence of phenylalanine, alliin, S-allylmercaptocysteine (SAMC), tryptophan, 1-methyl-1,2,3,4-tetrahydro-ß-carboline-3-carboxylic acid as major bioactive constituents of AGE. Metabolic studies, including intraperitoneal glucose tolerance test (IPGTT), revealed significantly lower blood glucose levels in the AGE group compared to the disease control group. In contrast, the intraperitoneal insulin tolerance test (ITT) exhibited no significant difference in insulin sensitivity between the AGE supplementation group and the DM control group. Interestingly, AGE was found to have no significant effect on fasting glucose and serum insulin levels. In contrast, AGE supplementation was found to cause significant hypoglycaemia in postprandial blood glucose and insulin levels. Importantly, AGE causes restoration of intracellular Ca2+ levels by modulation of SERCA/Ca2 functioning and inhibition NF-κB/TLR-4 pathway. AGE was found to interact with and inhibit the DR-5/ caspase-8/3 apoptotic complex. Furthermore, microscopic studies revealed degeneration and apoptotic changes in pancreatic ß-cells of the DM control group, while supplementation of AGE resulted in inhibition of apoptotic pathway and regeneration of pancreatic ß-cells. CONCLUSION: The current study suggests that AGE enhance glucose homeostasis by exerting their effects on pancreatic ß-cells, without ameliorating peripheral sensitivity. Moreover, AGEs promote an increase in ß-cell mass by mitigating the apoptosis of pancreatic ß-cells. These findings suggest that AGE could aid in developing a viable alternative therapy for diabetes mellitus (DM).

Primary hyperoxaluria: a case series.

BACKGROUND: Primary hyperoxaluria (PH) is a rare genetic disorder characterized by the excessive production and accumulation of oxalate. We present five cases of PH, each exhibiting varying manifestations of the disorder including a case presenting as postpartum kidney failure. Notably, three of these cases involve a previously unreported mutation. CASE PRESENTATIONS: We evaluated five Indian patients who presented with varying manifestations of PH. The first case, a 30 year old woman, presented as post-partum kidney failure and was found to be having oxalate nephropathy precipitated by dietary oxalate overload in the setting of previously undiagnosed PH. Genetic analysis revealed a previously unreported mutation in the alanine-glyoxylate aminotransferase gene. The patient underwent simultaneous kidney liver transplant. The second and third cases, 26 and 28 year old women respectively, were asymptomatic siblings of the first patient, who were diagnosed through screening. The fourth case is a 12 year boy with PH type 1 presenting as nephrolithiasis and rapidly worsening kidney function requiring combined kidney liver kidney transplant. Case 5 is a 6 year old male child with type 2 PH presenting with nephrolithiasis, nephrocalcinosis and normal kidney function. All the patients were born to consanguineous parents. CONCLUSIONS: Due to limited clinical suspicion and inadequate diagnostic resources in certain countries with limited resources, it is possible for PH to go undiagnosed. The manifestations of the disease can range from no noticeable symptoms to severe disease. Interestingly, in some individuals with primary hyperoxaluria, the disease may not exhibit any symptoms until it is triggered by a high intake of dietary oxalate.

Prevalence, Regional Variations, and Predictors of Overweight, Obesity, and Hypertension Among Healthy Reproductive-Age Indian Women: Nationwide Cross-Sectional Polycystic Ovary Syndrome Task Force Study.

BACKGROUND: A clear understanding of the anthropometric and sociodemographic risk factors related to BMI and hypertension categories is essential for more effective disease prevention, particularly in India. There is a paucity of nationally representative data on the dynamics of these risk factors, which have not been assessed among healthy reproductive-age Indian women. OBJECTIVE: This cross-sectional polycystic ovary syndrome (PCOS) task force study aimed to assess the anthropometric and sociodemographic characteristics of healthy reproductive-age Indian women and explore the association of these characteristics with various noncommunicable diseases. METHODS: We conducted a nationwide cross-sectional survey from 2018 to 2022 as part of the Indian Council of Medical Research-PCOS National Task Force study, with the primary aim of estimating the national prevalence of PCOS and regional phenotypic variations among women with PCOS. A multistage random sampling technique was adopted, and 7107 healthy women (aged 18-40 years) from 6 representative geographical zones of India were included in the study. The anthropometric indices and sociodemographic characteristics of these women were analyzed. Statistical analysis was performed to assess the association between exposure and outcome variables. RESULTS: Of the 7107 study participants, 3585 (50.44%) were from rural areas and 3522 (49.56%) were from urban areas. The prevalence of obesity increased from 8.1% using World Health Organization criteria to 40% using the revised consensus guidelines for Asian Indian populations. Women from urban areas showed higher proportions of overweight (524/1908, 27.46%), obesity (775/1908, 40.62%), and prehypertension (1008/1908, 52.83%) categories. A rising trend of obesity was observed with an increase in age. Women aged 18 to 23 years were healthy (314/724, 43.4%) and overweight (140/724, 19.3%) compared with women aged 36 to 40 years with obesity (448/911, 49.2%) and overweight (216/911, 23.7%). The proportion of obesity was high among South Indian women, with 49.53% (531/1072) and 66.14% (709/1072), using both World Health Organization criteria and the revised Indian guidelines for BMI, respectively. BMI with waist circumference and waist-to-height ratio had a statistically significant linear relationship (r=0.417; P<.001 and r=0.422; P<.001, respectively). However, the magnitude, or strength, of the association was relatively weak (0.3<|r|<0.5). Statistical analysis showed that the strongest predictors of being overweight or obese were older age, level of education, wealth quintile, and area of residence. CONCLUSIONS: Anthropometric and sociodemographic characteristics are useful predictors of overweight- and obesity-related syndromes, including prehypertension, among healthy Indian women. Increased attention to the health of Indian women from public health experts and policy makers is warranted. The findings of this study can be leveraged to offer valuable insights, informing health decision-making and targeted interventions that mitigate risk factors of overweight, obesity, and hypertension.

Pre-polycystic ovary syndrome and polymenorrhoea as new facets of polycystic ovary syndrome (PCOS): Evidences from a single centre data set.

OBJECTIVE: Polycystic ovary syndrome (PCOS) is a complex disorder with diverse metabolic implications. Diagnosis typically relies on oligo-amenorrhoea (OA), hyperandrogenism (HA), and polycystic ovarian morphology (PCOM). However, the role of polymenorrhoea in PCOS remains understudied. Additionally, limited information exists regarding metabolic disturbances in women with partial PCOS phenotypes that do not meet diagnostic criteria. This extensive database aims to provide substantial evidence on the metabolic implications of polymenorrhoea and partial PCOS phenotypes. DESIGN: Prospective observational study. PATIENTS AND MEASUREMENTS: In this single-centre study, 6463 women with PCOS-like characteristics and 3142 age-matched healthy women were included. The study compared clinical (anthropometry, modified Ferriman Gallwey [mFG] score), hormonal (serum testosterone), and metabolic (plasma glucose, serum lipids, insulin) characteristics between women diagnosed with PCOS, those with partial PCOS phenotypes, and the healthy control group RESULTS: In all, 5174 women met Rotterdam criteria for PCOS diagnosis, while 737 were classified as Pre-PCOS, including HA (n = 538), OA (n = 121), or PCOM (n = 78). Common clinical features included oligomenorrhoea (75.5%), hirsutism (82.9%), obesity (27.2%), hypertension (1.6%), metabolic syndrome (19.6%), and diabetes mellitus (5.6%). Women diagnosed with PCOS, HA only, and OA only exhibited higher average body mass index, plasma glucose levels (both fasting and 2 h after the oral glucose tolerance test), and lipid fractions in comparison to those with PCOM and the healthy controls. However, indices of insulin resistance were similar among women with PCOS, HA, PCOM, and OA, albeit higher than in the healthy controls. The polymenorrhoea subgroup (5.9%) had lower BMI and serum testosterone, but similar mFG score, plasma glucose, insulin, and lipid levels as the oligomenorrhoea subgroup. CONCLUSION: The metabolic disturbances observed in Pre-PCOS women highlight the need to reassess diagnostic criteria. Including the polymenorrhoea subcategory in PCOS criteria is recommended due to similar metabolic dysfunctions as the oligomenorrhoea group.

Normative range of various serum hormonal parameters among Indian women of reproductive age: ICMR-PCOS task force study outcome.

Background: The hormonal profile varies considerably with age, gender, ethnicity, diet or physiological state of an individual. Limited population-specific studies have studied the variations in hormonal parameters among apparently healthy women. We aimed to analyse the biological reference interval for various hormonal parameters in the reproductive-aged healthy Indian women. Methods: Out of 3877 participants that were clinically evaluated, 1441 subjects were subjected to laboratory investigations. All participants underwent a detailed clinical, biochemical and hormonal profiling. The hormone analysis was carried out at a single centre using a uniform methodology. Among the participants evaluated for biochemical and hormonal parameters, subjects that presented any abnormal profile or had incomplete investigations (n = 593) were excluded for further analysis. Findings: The mean age (±SD) of the subjects retained in the final analysis (n = 848) was 29.9 (±6.3) years. In the present study, the biological reference interval (2.5th-97.5th centile) observed were: serum T4: µg/dL (5.23-12.31), TSH: µg/mL (0.52-4.16) and serum prolactin: ng/mL (5.13-37.35), LH: mIU/mL (2.75-20.68), FSH: mIU/mL 2.59-15.12), serum total testosterone: ng/mL (0.06-0.68), fasting insulin: mIU/mL (1.92-39.72), morning cortisol: µg/dL (4.71-19.64), DHEAS:µg/dL (50.61-342.6) and SHBG: nmol/L (21.37-117.54). Unlike T4, TSH, LH, and E2, the biological reference interval for prolactin, FSH, testosterone, C-peptide insulin and DHEAS varied when the subjects were stratified by age (p < 0.05). The comparative analysis showed marginal differences in the normative ranges for the hormones analysed among different populations. Interpretation: Our first large composite data on hormonal measures will benefit future endeavours to define biological reference intervals in reproductive-aged Indian women. Funding: The study was financially supported by the grant-in-aid from ICMR vide file No:5/7/13337/2015-RBMH.

Do Pleiotropic Effects of Spironolactone in Women with PCOS Make it More than an Anti-androgen? Evidence from a Systematic Review and Meta-analysis.

BACKGROUND: Spironolactone use as a treatment for hirsutism and other dermatological conditions among polycystic ovary syndrome (PCOS) and idiopathic hirsutism shows varied results. OBJECTIVE: This study thus summarizes the entire evidence to better define its impact on Ferriman-Gallwey (FG) score in addition to other derangements associated with PCOS. METHODS: PubMed, Embase, Scopus and bibliographies of relevant articles were searched. Randomized controlled trails (RCTs) investigating the efficacy of spironolactone in PCOS and idiopathic hirsutism were included. Pooled mean difference (MD) was calculated using random effects model and relevant subgroup analysis was done. Potential heterogeneity and publication bias was assessed. RESULTS: Of 1041 retrieved studies, 24 RCTs were included. Spironolactone (100 mg/daily) exhibited a significant reduction in FG score in idiopathic hirsutism compared to finasteride (MD: -2.43; 95% C.I: -3.29, -1.57) and cyproterone acetate (MD: -1.18; 95% C.I: -2.10, -0.26), however, no significant difference was found among PCOS subjects in comparison to flutamide and finasteride. A lower dose of spironolactone (50 mg/day) exhibited no significant difference relative to metformin on FG Score (MD: -0.61; 95% C.I: -1.76, 0.54, I2 = 57%), serum total testosterone (MD: -0.61; 95% C.I: -1.76, 0.54), I2 = 57% and HOMA-IR (MD: 1.03; 95% C.I: -1.22, 3.29), I2 = 60% among PCOS women. The main side effects reported by the studies were menstrual irregularity, mild nausea, vomiting and diarrhea. CONCLUSION: Spironolactone is well tolerated among idiopathic hirsute and PCOS women. The drug significantly improved hirsutism in the former group and shows a positive trend in the latter women, however, displays no effect on FSH, LH, menstrual cyclicity, BMI, and HOMA-IR in PCOS women.

Insight into Oncogenic Viral Pathways as Drivers of Viral Cancers: Implication for Effective Therapy.

As per a recent study conducted by the WHO, 15.4% of all cancers are caused by infectious agents of various categories, and more than 10% of them are attributed to viruses. The emergence of COVID-19 has once again diverted the scientific community's attention toward viral diseases. Some researchers have postulated that SARS-CoV-2 will add its name to the growing list of oncogenic viruses in the long run. However, owing to the complexities in carcinogenesis of viral origin, researchers across the world are struggling to identify the common thread that runs across different oncogenic viruses. Classical pathways of viral oncogenesis have identified oncogenic mediators in oncogenic viruses, but these mediators have been reported to act on diverse cellular and multiple omics pathways. In addition to viral mediators of carcinogenesis, researchers have identified various host factors responsible for viral carcinogenesis. Henceforth owing to viral and host complexities in viral carcinogenesis, a singular mechanistic pathway remains yet to be established; hence there is an urgent need to integrate concepts from system biology, cancer microenvironment, evolutionary perspective, and thermodynamics to understand the role of viruses as drivers of cancer. In the present manuscript, we provide a holistic view of the pathogenic pathways involved in viral oncogenesis with special emphasis on alteration in the tumor microenvironment, genomic alteration, biological entropy, evolutionary selection, and host determinants involved in the pathogenesis of viral tumor genesis. These concepts can provide important insight into viral cancers, which can have an important implication for developing novel, effective, and personalized therapeutic options for treating viral cancers.

Efficacy and safety of various oral regimens (three oral doses) and schedules (daily v. monthly) of cholecalciferol in North Indian adults with low vitamin D status: evidence from a randomised controlled trial.

Vitamin D (VD) deficiency (serum 25 hydroxy vitamin D (25(OH)D) concentration of < 20 ng/ml), in endemic proportions, demands a supplementation strategy with optimal dosing regimens. A randomised parallel-group, active-controlled trial was conducted among apparently healthy, VD-deficient subjects, aged 18-60 years who received 600 µg/d (Group A), 1000 µg/d (Group B), 2000 µg/d (Group C) and 60 000 µg/month (Group D) of oral cholecalciferol. The intervention was carried in two phases (I and II) of 12 weeks each, with same dose, separated by a washout phase of 12 weeks. Serum 25(OH)D, intact parathyroid hormones (iPTH), Ca, phosphorous (PO4), alkaline phosphatase (ALP) and spot urine Ca/Cr were measured at baseline, 12, 24 and 36 weeks following the intervention, and adverse events were recorded at each occurrence and at 12, 24 and 36 weeks. A statistically significant time-group interaction was found in serum 25(OH)D concentration (P < 0·05). Serum 25(OH)D concentration increased significantly from baseline to 12 weeks (P < 0·05) in all the groups with no change at 24 weeks but further increase at 36 weeks (P < 0·05). At the end of the study, Group C had maximum increment in serum 25(OH)D concentration, while as Groups C and D (95 %, and 90 %) had higher proportion of subjects VD sufficient than Groups A and B (65 % and 78 %) (P < 0·05). No significant time-dose interactions were observed in serum iPTH, Ca, PO4 and ALP or urine Ca/Cr ratio. Three subjects (two in Group C and one in Group D) developed transient hypercalciuria. Supplementation with daily 2000 µg or monthly 60 000 µg of oral cholecalciferol among adults seems optimal and safe.

Ambulatory Blood Pressure Monitoring versus Office Blood Pressure Monitoring to Identify the True Hypertension Status of Living Kidney Donors.

Ambulatory blood pressure monitoring (ABPM) is a reliable modality and is preferred over office blood pressure monitoring (OBPM) for detecting hypertension. However, despite its advantages, the utilization of 24-h ABPM in evaluating living kidney donors has not been universally adopted by transplant centers, partly because of the lack of data about the utility of ABPM. This study aimed to identify patients with masked and white-coat hypertension, thereby ensuring appropriate identification of their true hypertension status and assessments of the risk to donors. This study included 73 potential living kidney donors. BP was measured in the office using a standardized protocol as well as by ABPM. Detailed clinical and biochemical parameters were assessed. Target organ damage was assessed in all the donors by assessing proteinuria, hypertensive retinopathy, and echocardiography. Out of the 73 donors, 64.4% were females and 35.6% were males. The average age of individuals in our donor population was 42.0 ± 11.28 years. In total, 31.5% were detected to be hypertensive by OBPM. With ABPM, only 21.9% of donors were hypertensive. The overall prevalence of white-coat hypertension was 30.4%; that of masked hypertension was 6.0%. In donors diagnosed as hypertensive by OBPM, three individuals were identified as having target organ damage. However, two additional donors who were initially missed as hypertensive using OBPM had target organ damage. OBPM overestimated the prevalence of hypertension compared with ABPM. ABPM is the better modality in terms of diagnosing white coats and masked hypertension. ABPM also more reliably correlates with target organ damage than OBPM.

Stereoselective Routes to Hexahydropyrroloindoles and Tetrahydropyrroloquinolines from Activated Aziridines and Electron Deficient 3H-Indoles.

An unprecedented and novel synthetic route to hexahydropyrrolo[2,3-b]indoles bearing cis-contiguous stereocenters with excellent stereoselectivities (ee of >99%, dr of ≤99:1) has been disclosed that proceeds through the ring opening of activated aziridines with electron deficient 4-substituted indoles followed by a novel cyclization in a domino fashion, thereby obviating the use of 3-substituted indoles as the prerequisite nucleophile. Another efficient synthetic route to tetrahydropyrrolo[4,3,2-de]quinolines in excellent yields (≤93%) and excellent enantioselectivity (ee of >99%) has been established via ring opening of activated aziridines with 4-bromo-1-methyl-1H-indole at relatively higher temperatures followed by Cu(I)-catalyzed intramolecular C-N cyclization in the same pot. The stability and the formation of products at different temperatures are explained by computational studies.

Clinical profile of patients presenting with thiamine-responsive upper-gastrointestinal upset: A pointer toward gastric beriberi.

OBJECTIVES: Although beriberi is considered a forgotten disease in the West, Kashmir has a rice-eating population that has beriberi in endemic proportions. Patients with a thiamine deficiency (TD) occasionally present with gastrointestinal (GI) symptoms, including nausea, recurrent vomiting, loss of appetite, and abdominal discomfort. Together these often respond to thiamine, which points to gastric beriberi. METHODS: Patients with GI symptoms suggestive of TD were recruited from the Department of Medicine at the Government Medical College and its associated hospital, SMHS, in Srinagar, India. Patients were evaluated for serum thiamine levels, serum lactate, biochemical parameters, and transabdominal ultrasonography after ruling out the usual causes of acute abdominal pain and vomiting. RESULTS: A total of 27 patients were recruited with a mean age of 47.28 ± 20.84 y. The mean lactate of patients at the time of admission was 6.43 ± 5.22 mmol/L, and the mean lactate at the time of discharge was 1.23 ± 0.50 mmol/L. All patients had a history of consuming polished rice, washed two to three times before cooking, as the staple diet. The most common GI symptoms were recurrent vomiting, nausea, and loss of appetite. All of the patients responded to the thiamine treatment, and showed improvement in their GI symptoms and decreased serum lactate levels within 2 to 6 h of their hospital stay. CONCLUSIONS: Gastric beriberi is a rare presentation of TD that can lead to severe GI symptoms and lactic acidosis. Given the rapid response to thiamine, it is the standard-of-care treatment in such cases. Thus, clinicians should suspect TD when patients present with either mild or moderate-to-severe GI symptoms and raised blood lactate.

Insights into New Therapeutic Approaches for the Treatment and Management of Polycystic Ovary Syndrome: An Updated Review.

BACKGROUND: Polycystic ovary syndrome (PCOS) is a long-term, highly prevalent, complex heterogeneous, polygenic endocrine disorder characterized by both metabolic and reproductive disorders. It affects 6-23% of reproductive-age women globally. OBJECTIVE: This review aims to facilitate an understanding of novel PCOS management approaches and highlight the results from relevant interventional animal and human studies. METHODS: Manual search on PubMed, Cochrane, and Scopus databases was performed for relevant articles, preclinical and clinical trials based on related keywords. RESULTS: According to a multitude of studies, PCOS has evolved over time, but a substantial lag remains in management approaches. New insights into the cross-talk between muscle, brain, fat, and ovaries pointed out new therapeutic targets. This review has highlighted the efficacy of a wide spectrum of novel therapeutic agents [Phosphodiesterase-4 Inhibitors, Glucagon-like peptide-1 receptor agonists, nutritional supplements (Vitamins D and K, omega-3, prebiotics, probiotics and synbiotics), fecal microbiota transplantation (FMT) and intestinal cytokine IL-22] as PCOS therapeutic options. These novel therapies combine anti-inflammatory, insulinsensitizing, and anti-obesity activities, along with the restoration of the gut microbiota and thus hold the potential to address the basic pathogenic mechanisms of PCOS. CONCLUSION: Exhaustive, multicentric and multiethnic studies are vital to generating a network of normative data to better figure out the PCOS trajectory and change prognostic outcomes. Preclinical and clinical data are warranted to corroborate the new therapeutics and direct health care resources accordingly.

Evaluation of the Prevalence, Regional Phenotypic Variation, Comorbidities, Risk Factors, and Variations in Response to Different Therapeutic Modalities Among Indian Women: Proposal for the Indian Council of Medical Research-Polycystic Ovary Syndrome (ICMR-PCOS) Study.

BACKGROUND: There is scanty data in India on polycystic ovary syndrome (PCOS) from several small, undersized, convenience-based studies employing differing diagnostic criteria and reporting varied regional prevalence. It is difficult to draw clear-cut conclusions from these studies; therefore, the present multicentric, well-designed, large-scale representative countrywide epidemiological study on PCOS across India was conceived with the aim to generate the actual prevalence rates of PCOS in India with a total sample size of approximately 9000 individuals. OBJECTIVE: The primary objectives of the study are to estimate the national prevalence of PCOS in India and the burden of comorbidities and to compare the variation in efficacy of standard therapeutic modalities for metabolic dysfunction in women with PCOS. METHODS: This multicentric umbrella study consists of three different substudies. Substudy 1 will involve recruitment of women aged 18-40 years using a multistage sampling technique from randomly selected polling booths across urban and rural areas to estimate national prevalence, phenotypic variation, and risk factors among regions. Substudy 2 involves recruitment of subjects from the community pool of substudy 1 and the institutional pool for quantitation of comorbidities among women with PCOS. Substudy 3, an interventional part of the study, aims for comparison of variation in efficacies of common treatment modalities and will be conducted only at 2 centers. The eligible consenting women will be randomized in a 1:1 ratio into 2 arms through a blinding procedure. All these women will undergo clinical, biochemical, and hormonal assessment at baseline and at 3 and 6 months. The data generated will be analyzed using the reliable statistical software SPSS (version 26). RESULTS: The study is ongoing and is likely to be completed by April 2022. The data will be compiled and analyzed, and the results of the study will be disseminated through publications. CONCLUSIONS: The Indian Council of Medical Research-PCOS study is the first of its kind attempting to provide accurate and comprehensive data on prevalence of PCOS in India.

Prevalence of diabetes and prediabetes in tribal population of Kashmir: Lessons for the future.

AIMS: Considering a surge in the incidence of Diabetes mellitus (DM) across all ethnic groups and lack of any representative data from the tribal communities of Jammu and Kashmir, the present study aimed to assess the prevalence of DM and prediabetes in them. METHODS: Subjects were recruited from five districts of Kashmir valley using multistage cluster sampling by probability proportional to size (PPS) technique. Data collection included recording of socio-demographic, medical facts, assessment of anthropometric parameters and biochemical evaluation HbA1c and random blood glucose measurements as per the American Diabetes Association (ADA) criteria were used for diagnosis of DM. RESULTS: A total of 6808 subjects were recruited in this study including 2872 (42%) men and 3936 (58%) women with mean age of 39.60 ± 20.19 years and 35.17 ± 16.70 years, respectively. Around 8.60% subjects were obese, 38.9% were found to be hypertensive, 73% had dyslipidemia and 3.75% had metabolic syndrome. About 1.26% (0.5% males and 0.9% females) had DM and 11.64% had prediabetes based on HbA1c cut offs. Increasing age, body mass index and family history portend significant risk factors while smoking and sedentary lifestyle increased the risk marginally. CONCLUSIONS: Although the prevalence of DM among tribals of Kashmir valley is lower than general population, the higher prediabetes to DM ratio may indicate a future trend of increasing DM prevalence in this disadvantageous subpopulation.

Differential Impact of Insulin Sensitizers vs. Anti-Androgen on Serum Leptin Levels in Vitamin D Replete PCOS Women: A Six Month Open Labeled Randomized Study.

Women with PCOS are linked to insulin resistance, inflammation, and vitamin D (VD) deficiency. The study endeavors to comprehend the differential impact of insulin sensitizers vs. anti-androgen on serum leptin levels among women with PCOS rendered vitamin D replete with high VD oral supplement. This was open-labeled randomized study that screened 180 eligible women presenting to Endocrine clinic with oligomenorrhea or features of hyperandrogenism. Ninety-nine women who furnished written informed consent and fulfilled the Rotterdam 2003 criteria for diagnosis of PCOS were randomized into 3 drug treatment arms to receive either spironolactone (50 mg/d; n=30), metformin (1000 mg/d; n=30) or pioglitazone (30 mg/d; n=30). These women were also administered oral VD (4000 IU/day) in addition to the allocated drug for a period of 6 months. Detailed history, clinical examination, and laboratory evaluation was carried out at baseline and 6 months after intervention. Number of menstrual cycles/year increased while as Ferriman-Gallwey score, blood glucose, HOMA-IR, and plasma insulin levels significantly decreased in all the three arms with better outcomes in spironolactone and pioglitazone arms (p<0.05). Similarly, serum leptin levels superiorly improved in spironolactone and pioglitazone group. Pioglitazone group showed better efficacy in lowering serum total testosterone (p<0.05). Co-supplementation of high dosage VD with spironolactone or pioglitazone are more effective in reducing plasma leptin levels than metformin, and thus might prove to be better therapeutic strategies for women with PCOS.

A synthetic route to 1,4-disubstituted tetrahydro-ß-carbolines and tetrahydropyranoindoles via ring-opening/Pictet-Spengler reaction of aziridines and epoxides with indoles/aldehydes.

A simple and efficient synthetic route to various 1,4-disubstituted tetrahydro-ß-carbolines and tetrahydropyrano[3,4-b]indoles in high yields and stereoselectivity via LiClO4-catalyzed SN2-type ring opening of aziridines and epoxides with indoles followed by p-toluenesulfonic acid (PTSA) catalyzed Pictet-Spengler reaction is described.

Stereoselective Syntheses of Highly Functionalized Imidazolidines and Oxazolidines via Ring-Opening Cyclization of Activated Aziridines and Epoxides with Amines and Aldehydes.

A mild one-pot stereospecific synthetic route to highly functionalized imidazolidines and oxazolidines via SN2-type ring-opening of the corresponding activated aziridines and epoxides with amines followed by p-toluenesulfonic acid (PTSA)-catalyzed intramolecular cyclization with aldehydes has been developed. The methodology tolerates a variety of functional groups and furnishes the desired products in high yields (up to 92%) with excellent stereoselectivities (de, ee > 99%). Interestingly, imidazolidines were formed as the cis-isomers, whereas oxazolidines were produced as trans-isomers exclusively.

Epidemiology, pathogenesis, genetics & management of polycystic ovary syndrome in India.

Polycystic ovary syndrome (PCOS) is a common endocrine disorder predominantly affecting women of reproductive age. Clinical manifestations are diverse including hyperandrogenism, anovulation, infertility and increased risk of metabolic diseases besides psychosocial dysfunction. This review provides information on the problem of PCOS in India, its pathophysiology, genetics and an overview of current management options to instigate further research in this field. Prevalence of PCOS in India ranges from 3.7 to 22.5 per cent depending on the population studied and the criteria used for diagnosis. Abnormalities in leptin-adiponectin (adipocyte biology), oxidative stress and autoimmunity are among the mechanisms studied regarding pathogenesis of PCOS. Many candidate gene studies have shown associations with PCOS in various studies. Studies have consistently demonstrated the relationship between the well-known manifestation of hyperandrogenism among Indian PCOS women and the metabolic morbidities including insulin resistance, glucose intolerance and cardiovascular risk. Management of individual components of PCOS can be achieved by medications or surgical methods, though further clarification regarding pathogenesis of PCOS is needed to sharpen our therapeutic armamentarium.

A Comparison between Silent and Symptomatic Renal Stones in Primary Hyperparathyroidism.

BACKGROUND: Nephrolithiasis is a common complication of primary hyperparathyroidism (PHPT), and in a subgroup of patients stones are clinically silent. Patients with silent and symptomatic stones may differ biochemically. There is a scarcity of data available comparing patients with silent and symptomatic renal stones in PHPT. AIMS: To characterize patients with PHPT with nephrolithiais and to compare patients with silent and symptomatic stones. MATERIALS AND METHODS: We reviewed clinical data of 186 patients with PHPT managed at our center from January 1996 to December 2017. Silent renal stones were defined as ultrasonography finding of renal stones without symptoms. Symptomatic renal stones were defined as those with symptoms or a history of graveluria or any procedure for nephrolithiasis. A 5-mm diameter was set as the cut-off between micro- and macrolithiasis. We compared those with (n = 95) and without (n = 91) stones, and, among stone formers, those with symptoms (n = 66) and silent (n = 29) were compared. RESULTS: There was no significant difference between stone formers and nonstone formers with respect to biochemical parameters. Patients with silent renal stones had significantly lower serum calcium and higher phosphate, than those with symptomatic stones. Most (75%) patients with silent renal stones had microlithiais, while only a fifth (22%) with symptomatic renal stones had microlithiasis. CONCLUSION: Nephrolithiasis is a common complication of PHPT. Most patients with silent renal stones had microlithiasis and biochemical features of less severe disease. Patients with silent renal stones may represent early mild stage of PHPT.
