RESUMO

Preterm birth is a leading cause of perinatal morbidity and mortality and Preterm premature rupture of the membranes (PPROM) is a major risk factor contributing to approximately one third of preterm deliveries. Vaginal infections are often associated with PPROM and are characterised by loss of lactobacillin normal vaginal flora and overgrowth of other pathogenic microorganisms. Probiotics appear to have an emerging role in prolonging pregnancy after PPROM. This trial compared the efficacy of a vaginal probiotic in combination with standard antibiotic prophylaxis versus only antibiotic in prolongation of latency period and on perinatal outcome in cases of PPROM between 24 and 34 weeks. Although no significant difference was observed in the mean latency period (p = 0.937) and mean gestational age at birth (p = 0.863) between the two groups, the overall neonatal outcome was better in the study group. There is need of further large-scale clinical trials to demonstrate effectiveness of probiotics.IMPACT STATEMENTWhat is already known on this subject? PPROM is an important cause of preterm birth. Prematurity leads significant global burden of neonatal morbidity and mortality. Antibiotics in PPROM have a proven benefit to prolong latency period from start of PPROM to birth. Probiotics have a role in improving vaginal flora and reducing infections and have been tried in PPROM.What do the results of this study add? The usefulness of probiotics in prolonging latency period and improving neonatal outcome has been reported in limited trials. In our study it has shown an improvement in neonatal outcome overall but not statistically significant compared to few studies which have reported significant beneficial effects. This might be due to existence of variation in the type of the vaginal microflora in different study population.What are the implications of these findings for clinical practice and/or further research? Preliminary results suggest that use of probiotic may benefit women with PPROM. This also implies need of multicentric larger scales trials with different types of probiotics so as to clarify whether any intervention in vaginal microflora can lead to any benefits in reducing the prematurity and its consequence, both on the neonate and heath care infrastructure.

RESUMO

BACKGROUND: Maternal morbidity occurs several times more frequently than mortality, yet data on morbidity burden and its effect on maternal, foetal, and newborn outcomes are limited in low- and middle-income countries. We aimed to generate prospective, reliable population-based data on the burden of major direct maternal morbidities in the antenatal, intrapartum, and postnatal periods and its association with maternal, foetal, and neonatal death in South Asia and sub-Saharan Africa. METHODS AND FINDINGS: This is a prospective cohort study, conducted in 9 research sites in 8 countries of South Asia and sub-Saharan Africa. We conducted population-based surveillance of women of reproductive age (15 to 49 years) to identify pregnancies. Pregnant women who gave consent were include in the study and followed up to birth and 42 days postpartum from 2012 to 2015. We used standard operating procedures, data collection tools, and training to harmonise study implementation across sites. Three home visits during pregnancy and 2 home visits after birth were conducted to collect maternal morbidity information and maternal, foetal, and newborn outcomes. We measured blood pressure and proteinuria to define hypertensive disorders of pregnancy and woman's self-report to identify obstetric haemorrhage, pregnancy-related infection, and prolonged or obstructed labour. Enrolled women whose pregnancy lasted at least 28 weeks or those who died during pregnancy were included in the analysis. We used meta-analysis to combine site-specific estimates of burden, and regression analysis combining all data from all sites to examine associations between the maternal morbidities and adverse outcomes. Among approximately 735,000 women of reproductive age in the study population, and 133,238 pregnancies during the study period, only 1.6% refused consent. Of these, 114,927 pregnancies had morbidity data collected at least once in both antenatal and in postnatal period, and 114,050 of them were included in the analysis. Overall, 32.7% of included pregnancies had at least one major direct maternal morbidity; South Asia had almost double the burden compared to sub-Saharan Africa (43.9%, 95% CI 27.8% to 60.0% in South Asia; 23.7%, 95% CI 19.8% to 27.6% in sub-Saharan Africa). Antepartum haemorrhage was reported in 2.2% (95% CI 1.5% to 2.9%) pregnancies and severe postpartum in 1.7% (95% CI 1.2% to 2.2%) pregnancies. Preeclampsia or eclampsia was reported in 1.4% (95% CI 0.9% to 2.0%) pregnancies, and gestational hypertension alone was reported in 7.4% (95% CI 4.6% to 10.1%) pregnancies. Prolonged or obstructed labour was reported in about 11.1% (95% CI 5.4% to 16.8%) pregnancies. Clinical features of late third trimester antepartum infection were present in 9.1% (95% CI 5.6% to 12.6%) pregnancies and those of postpartum infection in 8.6% (95% CI 4.4% to 12.8%) pregnancies. There were 187 pregnancy-related deaths per 100,000 births, 27 stillbirths per 1,000 births, and 28 neonatal deaths per 1,000 live births with variation by country and region. Direct maternal morbidities were associated with each of these outcomes. CONCLUSIONS: Our findings imply that health programmes in sub-Saharan Africa and South Asia must intensify their efforts to identify and treat maternal morbidities, which affected about one-third of all pregnancies and to prevent associated maternal and neonatal deaths and stillbirths. TRIAL REGISTRATION: The study is not a clinical trial.

RESUMO

We studied bone mineral content (BMC), bone mineral density (BMD), and body composition in offspring of women supplemented with vitamin D during pregnancy. Pregnant women were randomized to receive oral cholecalciferol 60,000 units 4 weekly (group 1), 8 weekly (group 2), or placebo (group 3). All received 1 g calcium daily (groups 1 and 2 without, and group 3 with 400 units vitamin D). Offspring at 12-16 months underwent dual-energy X-ray absorptiometry. Maternal hypovitaminosis D at recruitment was common (serum 25OHD <50 nmol/L in 88 %) and severe (25OHD <25 nmol/L in 46 %). Groups 1 and 2 (n = 23 and 13, median age 14 months) had higher cord blood 25OHD (47.8 ± 13.8 and 31.0 ± 14.0 nmol/L) versus group 3 (n = 16, median age 16 months, 17.8 ± 13.5 nmol/L, p < 0.001). Babies in group 3 had higher whole-body BMC (250.8 ± 42.5 gm) and BMD (0.335 ± 0.033 gm/cm2) compared to group 1 (213.1 ± 46.2 gm and 0.295 ± 0.041 gm/cm2) and group 2 (202.9 ± 29.9 gm and 0.287 ± 0.023 gm/cm2) (p = 0.006 and 0.001, respectively). In multivariate analysis, age, weight z score, and lean body mass remained significant contributors to BMC. Parameters of body composition were comparable among the groups. Vitamin D supplementation to pregnant women with severe deficiency in doses that improved cord blood 25OHD did not result in improved bone health or body composition in offspring at 12-16 months, compared to a dose too small to improve 25OHD levels.

RESUMO

We assessed the effect of vitamin D supplementation on related biochemistry, infection and dentition of the infant. In a double-blind, placebo-controlled trial conducted in Lucknow, India (latitude 26°N), 230 mother -newborn pairs were randomised to receive, for 9 months, 3000µg/month oral vitamin D3 by the mother (group A) or 10µg/d by the infant (group B) or double placebo (group C). All babies received 15 min of sun exposure (unclothed) during massage. Infants' median 25-hydroxyvitamin D (25(OH)D) was lower in group C (median 45·3; interquartile range (IQR) 22-59·5 nmol/l) than in groups A (median 60·8; IQR 41·3-80·5 nmol/l (P7.5µkat/l) was significantly more frequent in group C babies (16 %) than in group A (4 %) or group B (0 %) babies. The number of days with respiratory or diarrhoeal infection by 9 months of age was higher in group C (median 46·5; IQR 14·8-73·3 d) than in group A (median 18·5; IQR 8·8-31·0 d (P<0·01)) or group B (median 13·0; IQR 7·0-28·5 (P<0·05)). We conclude that monthly maternal or daily infant supplementation with vitamin D along with sun exposure is superior to sun exposure alone in maintaining normal infant 25(OH)D at 3·5 months, and provide protection from elevated alkaline phosphatase and infectious morbidity.

RESUMO

BACKGROUND & OBJECTIVES: Despite their high occurrence and associated significant level of morbidity manifesting as spectrum of clinical symptoms, the pathogenesis of uterine leiomyomas (ULs) remains unclear. We investigated expression profile of tumour suppressor genes PTEN (phosphatase and tensin homolog deleted on chromosome ten) and LKB1 (liver kinase B1), and key signaling components of P13K (phosphatidylinositol 3-kinase)/Akt (protein kinase B)/mTOR (mammalian target of rapamycin) pathway in leiomyomas and adjacent normal myometrium in women of reproductive age, to explore the possibility of targeting this pathway for future therapeutic implications. METHODS: Real time PCR (qPCR) was used to quantify relative gene expression levels of PTEN, Akt1, Akt2, mTOR, LKB1 and VEGFA (vascular endothelial growth factor A) in leiomyoma as compared to adjacent normal myometrium. Immunohistochemistry was subsequently performed to analyze expression of PTEN, phospho-Akt, phospho-mTOR, phospho-S6, LKB1 and VEGFA in leiomyoma and adjacent normal myometrium. RESULTS: Significant upregulation of PTEN (2.52 fold; P=0.03) and LKB1 (3.93 fold; P0.01), and downregulation of VEGFA (2.95 fold; P=0.01) genes were observed in leiomyoma as compared to normal myometrium. Transcript levels of Akt1, Akt2 and mTOR did not vary significantly between leiomyoma and myometrium. An increased immunoexpression of PTEN (P=0.015) and LKB1 (P<0.001) and decreased expression of VEGFA (P=0.01) was observed in leiomyoma as compared to myometrium. Immunostaining for activated (phosphorylated) Akt, mTOR and S6 was absent or low in majority of leiomyoma and myometrium. INTERPRETATION & CONCLUSIONS: Upregulation of PTEN and LKB1 in concert with negative or low levels of activated Akt, mTOR and S6 indicates that PI3K/Akt/mTOR pathway may not play a significant role in pathogenesis of leiomyoma.

RESUMO

BACKGROUND: Verbal autopsy (VA) is recognized as the only feasible alternative to comprehensive medical certification of deaths in settings with no or unreliable vital registration systems. However, a barrier to its use by national registration systems has been the amount of time and cost needed for data collection. Therefore, a short VA instrument (VAI) is needed. In this paper we describe a shortened version of the VAI developed for the Population Health Metrics Research Consortium (PHMRC) Gold Standard Verbal Autopsy Validation Study using a systematic approach. METHODS: We used data from the PHMRC validation study. Using the Tariff 2.0 method, we first established a rank order of individual questions in the PHMRC VAI according to their importance in predicting causes of death. Second, we reduced the size of the instrument by dropping questions in reverse order of their importance. We assessed the predictive performance of the instrument as questions were removed at the individual level by calculating chance-corrected concordance and at the population level with cause-specific mortality fraction (CSMF) accuracy. Finally, the optimum size of the shortened instrument was determined using a first derivative analysis of the decline in performance as the size of the VA instrument decreased for adults, children, and neonates. RESULTS: The full PHMRC VAI had 183, 127, and 149 questions for adult, child, and neonatal deaths, respectively. The shortened instrument developed had 109, 69, and 67 questions, respectively, representing a decrease in the total number of questions of 40-55%. The shortened instrument, with text, showed non-significant declines in CSMF accuracy from the full instrument with text of 0.4%, 0.0%, and 0.6% for the adult, child, and neonatal modules, respectively. CONCLUSIONS: We developed a shortened VAI using a systematic approach, and assessed its performance when administered using hand-held electronic tablets and analyzed using Tariff 2.0. The length of a VA questionnaire was shortened by almost 50% without a significant drop in performance. The shortened VAI developed reduces the burden of time and resources required for data collection and analysis of cause of death data in civil registration systems.

RESUMO

BACKGROUND: Reliable data on the distribution of causes of death (COD) in a population are fundamental to good public health practice. In the absence of comprehensive medical certification of deaths, the only feasible way to collect essential mortality data is verbal autopsy (VA). The Tariff Method was developed by the Population Health Metrics Research Consortium (PHMRC) to ascertain COD from VA information. Given its potential for improving information about COD, there is interest in refining the method. We describe the further development of the Tariff Method. METHODS: This study uses data from the PHMRC and the National Health and Medical Research Council (NHMRC) of Australia studies. Gold standard clinical diagnostic criteria for hospital deaths were specified for a target cause list. VAs were collected from families using the PHMRC verbal autopsy instrument including health care experience (HCE). The original Tariff Method (Tariff 1.0) was trained using the validated PHMRC database for which VAs had been collected for deaths with hospital records fulfilling the gold standard criteria (validated VAs). In this study, the performance of Tariff 1.0 was tested using VAs from household surveys (community VAs) collected for the PHMRC and NHMRC studies. We then corrected the model to account for the previous observed biases of the model, and Tariff 2.0 was developed. The performance of Tariff 2.0 was measured at individual and population levels using the validated PHMRC database. RESULTS: For median chance-corrected concordance (CCC) and mean cause-specific mortality fraction (CSMF) accuracy, and for each of three modules with and without HCE, Tariff 2.0 performs significantly better than the Tariff 1.0, especially in children and neonates. Improvement in CSMF accuracy with HCE was 2.5%, 7.4%, and 14.9% for adults, children, and neonates, respectively, and for median CCC with HCE it was 6.0%, 13.5%, and 21.2%, respectively. Similar levels of improvement are seen in analyses without HCE. CONCLUSIONS: Tariff 2.0 addresses the main shortcomings of the application of the Tariff Method to analyze data from VAs in community settings. It provides an estimation of COD from VAs with better performance at the individual and population level than the previous version of this method, and it is publicly available for use.

RESUMO

BACKGROUND: Monitoring progress with disease and injury reduction in many populations will require widespread use of verbal autopsy (VA). Multiple methods have been developed for assigning cause of death from a VA but their application is restricted by uncertainty about their reliability. METHODS: We investigated the validity of five automated VA methods for assigning cause of death: InterVA-4, Random Forest (RF), Simplified Symptom Pattern (SSP), Tariff method (Tariff), and King-Lu (KL), in addition to physician review of VA forms (PCVA), based on 12,535 cases from diverse populations for which the true cause of death had been reliably established. For adults, children, neonates and stillbirths, performance was assessed separately for individuals using sensitivity, specificity, Kappa, and chance-corrected concordance (CCC) and for populations using cause specific mortality fraction (CSMF) accuracy, with and without additional diagnostic information from prior contact with health services. A total of 500 train-test splits were used to ensure that results are robust to variation in the underlying cause of death distribution. RESULTS: Three automated diagnostic methods, Tariff, SSP, and RF, but not InterVA-4, performed better than physician review in all age groups, study sites, and for the majority of causes of death studied. For adults, CSMF accuracy ranged from 0.764 to 0.770, compared with 0.680 for PCVA and 0.625 for InterVA; CCC varied from 49.2% to 54.1%, compared with 42.2% for PCVA, and 23.8% for InterVA. For children, CSMF accuracy was 0.783 for Tariff, 0.678 for PCVA, and 0.520 for InterVA; CCC was 52.5% for Tariff, 44.5% for PCVA, and 30.3% for InterVA. For neonates, CSMF accuracy was 0.817 for Tariff, 0.719 for PCVA, and 0.629 for InterVA; CCC varied from 47.3% to 50.3% for the three automated methods, 29.3% for PCVA, and 19.4% for InterVA. The method with the highest sensitivity for a specific cause varied by cause. CONCLUSIONS: Physician review of verbal autopsy questionnaires is less accurate than automated methods in determining both individual and population causes of death. Overall, Tariff performs as well or better than other methods and should be widely applied in routine mortality surveillance systems with poor cause of death certification practices.

RESUMO

Endometriosis, affecting approximately 10% of reproductive-aged women globally, poses significant challenges, including chronic pelvic pain, dysmenorrhea, and infertility. In low- and middle-income countries like India, accessibility to affordable infertility care remains a concern. This multicenter prospective cohort study, conducted across six tertiary care hospitals in India from 2017 to 2022, aims to explore the natural progression of conception and pregnancy outcomes in women with endometriosis. Of the 257 participants, 19.1% conceived during the study, revealing significant geographic and income-based variations (p < 0.001, p = 0.01). Dysmenorrhea (p < 0.001) and dyspareunia (p=0.027) were correlated with conception, while no such associations were found with chronic pelvic pain or menstrual factors. Lesion type, number, and severity showed no conclusive link with conception. Natural conception occurred in 70% of cases, with an average post-surgery conception time of 282.1 days. Live birth rate was 85.7%, while complications included placenta previa (16.4%), preeclampsia (4.1%), and preterm births (4.1%). This study, one of the first in India on endometriosis-related fertility progression, emphasizes the need for comprehensive understanding and management of conception and pregnancy outcomes. Considering India's substantial endometriosis burden, the study recommends prioritizing larger multicenter investigations for a better understanding and effective strategies for infertility management.

RESUMO

BACKGROUND & OBJECTIVES: Asymptomatic bacteriuria during pregnancy if left untreated, may lead to acute pyelonephritis, preterm labour, low birth weight foetus, etc. Adequate and early treatment reduces the incidence of these obstetric complications. The present study was done to determine presence of asymptomatic bacteriuria (ASB) and obstetric outcome following treatment in early versus late pregnancy. METHODS: A prospective cohort study was conducted at a tertiary care teaching hospital of north India. Pregnant women till 20 wk (n=371) and between 32 to 34 wk gestation (n=274) having no urinary complaints were included. Their mid stream urine sample was sent for culture and sensitivity. Women having > 10 [5] colony forming units/ml of single organism were diagnosed positive for ASB and treated. They were followed till delivery for obstetric outcome. Relative risk with 95% confidence interval was used to describe association between ASB and outcome of interest. RESULTS: ASB was found in 17 per cent pregnant women till 20 wk and in 16 per cent between 32 to 34 wk gestation. Increased incidence of preeclamptic toxaemia (PET) [RR 3.79, 95% CI 1.80-7.97], preterm premature rupture of membrane (PPROM)[RR 3.63, 45% CI 1.63-8.07], preterm labour (PTL) [RR 3.27, 95% CI 1.38-7.72], intrauterine growth restriction (IUGR)[RR 3.79, 95% CI 1.80-79], low birth weight (LBW) [RR1.37, 95% CI 0.71-2.61] was seen in late detected women (32-34 wk) as compared to ASB negative women, whereas no significant difference was seen in early detected women (till 20 wk) as compared to ASB negative women. INTERPRETATION & CONCLUSIONS: Early detection and treatment of ASB during pregnancy prevents complications like PET, IUGR, PTL, PPROM and LBW. Therefore, screening and treatment of ASB may be incorporated as routine antenatal care for safe motherhood and healthy newborn.

RESUMO

BACKGROUND: Breast pain and non-discrete breast nodularity are common in women. METHODS: We did a randomized, double-blind, placebocontrolled trial of oral ormeloxifene 30 mg, a selective oestrogen receptor modulator (SERM) or placebo twice a week for 3 months in 20-50-year-old women with breast pain with or without lumpiness. Women with a discrete benign lump or cancer were excluded from the study. Serial assessments of pain on a visual analogue scale and nodularity grade on a 5-point ordinal Lucknow-Cardiff scale were done. A total of 151 patients were randomly allocated to two interventions using a block size of 4. RESULTS: Of the 151 patients, 121 (active 57, placebo 64) were available for efficacy analysis. The mean pain level showed a systematic downward trend over five visits (F=105.23, p<0.0001) that significantly reduced in the active group compared to that in the placebo group (F=18.66, p<0.0001). The patterns of variation in pain over time for the individual groups differ from the overall mean pattern for the two groups and thus from one another (F=44.43, p<0.0001). Cumulative frequencies of breast nodularity grades during successive visits showed significant improvement (p=0.001) compared to placebo at the end of the third month. The effect of the active drug persisted till the completion (6 months) of treatment (p<0.001). At the last visit, 93.3% of women in the active group had grade 2 or lower nodularity as compared to 71.1% in the placebo group. Oligomenorrhoea alone was reported by 12 patients. CONCLUSION: Ormeloxifene showed significant efficacy for treating breast pain and nodularity.

RESUMO

Background: Preeclampsia affects 2% to 8% of pregnant women and significantly increases the risk for maternal and perinatal morbidity, especially in low- and middle-income countries. There is increasing evidence to support the use of biochemical markers such as placental growth factor and soluble fms-like tyrosine kinase-1 in predicting the severity of preeclampsia and to rule out severe disease in clinical conditions masquerading as severe preeclampsia. OBJECTIVE: This study aimed to assess the role of the sFlt-1/PlGF ratio in predicting adverse perinatal and maternal outcomes in women with preeclampsia in a South Asian population with a higher rate of the disease and its associated complications. STUDY DESIGN: This was a prospective cohort study of women diagnosed with preeclampsia or suspected to have preeclampsia who underwent biophysical and biochemical investigations to measure the severity, including determining maternal hemodynamic indices, mean arterial pressure, fetal biometric and Doppler parameters, and soluble fms-like tyrosine kinase-1 and placental growth factor levels. The performance of these markers, individually or in combination, in predicting adverse perinatal and maternal outcomes was then assessed using receiver operating characteristic curve analysis. An adverse maternal outcome was defined as 1 or more of severe hypertension; admission to the intensive care unit; eclampsia; placental abruption; hemolysis, elevated liver enzymes, low-platelet count syndrome; disseminated intravascular coagulation; platelets <100×109/L; creatinine >1.1 mg/dL; and alanine aminotransferase >100 U/L. An adverse perinatal outcome was defined as 1 or more of preterm birth ≤34+0 weeks' gestation, neonatal intensive care unit admission for >48 hours, respiratory distress syndrome, intraventricular hemorrhage, hypoxic ischemic encephalopathy, necrotizing enterocolitis, retinopathy of prematurity, and confirmed fetal infection. RESULTS: We recruited 91 women with preeclampsia with a mean gestational age of 30.63±2.86 weeks. Women who had adverse maternal events had higher median maternal concentrations of soluble fms-like tyrosine kinase (11,500.0 pg/mL vs 3051.0 pg/mL; P<.001), lower concentrations of placental growth factor (44.88 pg/mL vs 148.50 pg/mL; P<.001), and a higher sFlt-1/PlGF ratio (306.22 vs 30.63; P<.001) than women who did not. Pregnancies with an adverse perinatal outcome also had a higher soluble fms-like tyrosine kinase concentration (12,100.0 pg/mL vs 3051.0 pg/mL; P<.001), lower placental growth factor concentration (27.2 pg/mL vs 148.50 pg/mL; P<.001), and higher sFlt-1/PlGF ratio (378.45.4 vs 30.63; P<.001). The area under the receiver operating characteristic curve showed that soluble fms-like tyrosine kinase and placental growth factor were the best biomarkers when compared with other biochemical markers to predict adverse maternal (area under the curve, 0.81; 95% confidence interval, 0.72-0.90) and fetal (area under the curve, 0.88; 95% confidence interval, 0.80-0.96) outcomes in preeclampsia. CONCLUSION: The sFlt-1/PlGF ratio correlates better with adverse maternal and perinatal outcomes than any other biochemical marker in an Indian population. The incorporation of the sFlt-1/PlGF ratio in women with preeclampsia can help in predicting the severity of the condition and the timings of the delivery.

RESUMO

Introduction: Gestational diabetes is defined as the carbohydrate intolerance of variable severity with onset or first recognition during pregnancy. Gestational glucose intolerance (GGI) is used to indicate pregnant women whose 2-h postprandial glucose is > 120 mg/dl and below 140 mg/dl (Diabetes in Pregnancy Study Group of India, DIPSI criteria). Aim: This study was planned to see whether intervention in GGI group helps to improve feto-maternal outcomes. Methodology: This open-label randomized control trial was conducted in Department of Obstetrics and Gynaecology of King George's Medical University, Lucknow. Inclusion criteria were all the antenatal women attending the antenatal clinic and diagnosed as GGI, and exclusion criteria were overt diabetes. Results: Total of 1866 antenatal women were screened, and among them, 220 (11.8%) women were diagnosed as gestational diabetes; 412 (22.1%) women were diagnosed as GGI. The mean fasting blood sugars in the women with GGI who had medical nutrition therapy were much lower than the women with GGI who did not have any intervention. The present study showed the women with GGI had higher complications like polyhydramnios, PPROM, foetal growth restriction, macrosomia, preeclampsia, preterm labour and vaginal candidiasis more in the women with GGI as compared to euglycaemic women. Conclusion: The present study of nutritional intervention in GGI group has shown trend towards lesser complication if we start medical nutrition therapy reflected by delayed development of GDM and less neonatal hypoglycaemia and hyperbilirubinemia.

RESUMO

Hypovitaminosis D is common in India. In the present prospective partially randomised study of vitamin D (D3) supplementation during pregnancy, subjects were randomised in the second trimester to receive either one oral dose of 1500 µg vitamin D3 (group 1, n 48) or two doses of 3000 µg vitamin D3 each in the second and third trimesters (group 2, n 49). Maternal 25-hydroxyvitamin D (25(OH)D) at term, cord blood (CB) alkaline phosphatase (ALP), neonatal serum Ca and anthropometry were measured in these subjects and in forty-three non-supplemented mother-infant pairs (usual care). Median maternal 25(OH)D at term was higher in group 2 (58·7, interquartile range (IQR) 38·4-89·4 nmol/l) v. group 1 (26·2, IQR 17·7-57·7 nmol/l) and usual-care group (39·2, IQR 21·2-73·4 nmol/l) (P = 0·000). CB ALP was increased (>8.02 µkat/l or >480 IU/l) in 66·7 % of the usual-care group v. 41·9 % of group 1 and 38·9 % of group 2 (P = 0·03). Neonatal Ca and CB 25(OH)D did not differ significantly in the three groups. Birth weight, length and head circumference were greater and the anterior fontanelle was smaller in groups 1 and 2 (3·08 and 3·03 kg, 50·3 and 50·1 cm, 34·5 and 34·4 cm, 2·6 and 2·5 cm, respectively) v. usual care (2·77 kg, 49·4, 33·6, 3·3 cm; P = 0·000 for length, head circumference and fontanelle and P = 0·003 for weight). These differences were still evident at 9 months. We conclude that both 1500 µg and two doses of 3000 µg vitamin D3 had a beneficial effect on infant anthropometry, the larger dose also improving CB ALP and maternal 25(OH)D.

RESUMO

PI3K-Akt-mTOR and MAP kinase are two important cell signaling pathways that are activated by steroid hormones and growth factors leading to cellular events including gene expression, cell proliferation and survival. These pathways are considered as an attractive target for the development of novel anticancer molecules, and selective inhibitors specifically targeting different components of these cascades have been developed. This review summarizes the current available knowledge on the PI3K-Akt-mTOR and MAPK pathways and their targeting in estrogen-dependent benign gynecological disorders viz. polycystic ovarian syndrome, uterine leiomyomas and endometriosis, which are a significant cause of high morbidity in women of reproductive age group. Increasing knowledge about the role of the two growth regulatory pathways in the pathogenesis of these disorders may give the opportunity to use specific signal transduction inhibitors for management of these patients in future.

RESUMO

BACKGROUND: Various reports suggest that HLA-G molecule plays an important role in feto-maternal interface, protecting the allogenic fetus from maternal immune attack. It is shown that steroid hormones may upregulate the HLA-G gene expression. In the present study, we have made an attempt to upregulate the HLA-G gene expression in a HLA-G(+ve) cell line (JEG-3) by using two glucocorticoids drugs, i.e., dexamethasone and hydrocortisone. METHODS: Choriocarcinoma JEG-3 (HLA-G(+ve)), JAR (HLA-G(-ve)) and erythroleukemia K-562 (HLA-G(-ve)) cell lines were obtained from American Type Culture Collection. These cell lines were treated with glucocorticoids (dexamethasone and hydrocortisone). HLA-G gene transcription was determined by standard and real-time RT-PCR analysis, and protein expression was evaluated by both flow cytometry and Western blotting. RESULTS: Dose-dependent increase in HLA-G mRNA and protein expression was observed in HLA-G(+ve) JEG-3 cells, while no expression was recorded in JAR and K-562 (HLA-G(-ve)) cell lines. CONCLUSION: We were able to upregulate HLA-G expression only in HLA-G(+ve) cell line. On the basis of our results, we hypothesize that the HLA-G gene expression can be upregulated only when the cell lines/cells have the basal expression and not in the cells that totally lack its expression. We have further hypothesized that these drugs may be used only in those women with recurrent miscarriages who show minimum basal expression level of HLA-G.

RESUMO

Background: Interpregnancy interval (IPI) is spacing between live birth and beginning a new pregnancy. Both long and short IPIs have been associated with adverse maternal outcomes. There is paucity in the Indian literature regarding the impact of IPI on maternal outcomes. Materials and Methodology: The cross-sectional study was conducted in the Department of Obstetrics and Gynecology, King George's Medical University, Lucknow, from July 2019 to June 2020. Women with previous abortions, previous stillbirth, nulliparity, or multiple pregnancies were excluded. A pre-structured pro forma was used for demographic details. IPI was categorized as <6 months, 6 to <24 months, 24 to <60 months, and 60 months. Maternal outcomes were studied, and odds ratios were calculated. Results: There were 6984 deliveries in the period. A total of 4812 women were enrolled after following the inclusion and exclusion criteria. Of 4812 women, 142 (2.9%) had IPI <6 months, 3336/4812 women (69.3%) had IPI 6 to <24 months, 1144/4812 women (23.7%) had IPI 24 to <60 months, and 3.9% women (190/4812) had IPI ≥60 months. High risk of fetal malposition (OR 3.84), fetal growth restriction (OR 2.06), and hypertension (OR 1.86) were seen in women with short IPI <6 months. Women with longer IPI (≥ 60 months) had higher chances of preterm labor (OR 3.82), oligoamnios (OR 2.54), gestational diabetes (OR 2.19), and anemia (OR 1.45). Conclusion: Three-fourths of women had IPI less than 24 months recommended as minimum interval by WHO. Efforts are needed to increase awareness and availability of contraceptive choices for postpartum women to ensure adequate spacing.

RESUMO

OBJECTIVE: To study clinical, surgical characteristics and the relationship between endometriosis lesion types and conception rate after surgery in infertile women with endometriosis. METHODS: A prospective, multicenter cohort of 204 women (age 20-35 years) with endometriosis was followed up post-surgery between November 2017 and February 2020 at three tertiary-care hospitals. RESULTS: Based on the severity of endometriosis lesion type, deep infiltrating endometriosis (DIE) (81/204, 39.7%) was the most common lesion; followed by ovarian endometriosis (OMA) (64/204, 31.4%), and superficial peritoneal endometriosis (SUP) (59/204, 28.9%). Endometriosis patients had a single lesion type (94/204, 46.1%), two lesion types (77/204, 37.7%), or three lesion types (33/204, 16.2%) with significant differences between regions (P < 0.001). Around 40% (37/95) of obese women had SUP (P = 0.003) whereas 78% (14/18) of underweight women had DIE (P < 0.001). Significant differences in mean Endometriosis Fertility Index scores between endometriosis lesion types and patients with one, two, and three types of lesions were observed (P < 0.001). The majority (22/32, 68.8%) of the women conceived naturally after the surgery. Half (16/32; 50%) of the women with a single lesion type conceived after the surgery; of which most (13/16, 81.2%) had SUP, followed by OMA (2/16, 12.5%), and DIE (1/16, 6.3%). CONCLUSION: Women with SUP and only one type of endometriotic lesion were more likely to conceive post-surgery.

RESUMO

BACKGROUND: Verbal autopsy methods are critically important for evaluating the leading causes of death in populations without adequate vital registration systems. With a myriad of analytical and data collection approaches, it is essential to create a high quality validation dataset from different populations to evaluate comparative method performance and make recommendations for future verbal autopsy implementation. This study was undertaken to compile a set of strictly defined gold standard deaths for which verbal autopsies were collected to validate the accuracy of different methods of verbal autopsy cause of death assignment. METHODS: Data collection was implemented in six sites in four countries: Andhra Pradesh, India; Bohol, Philippines; Dar es Salaam, Tanzania; Mexico City, Mexico; Pemba Island, Tanzania; and Uttar Pradesh, India. The Population Health Metrics Research Consortium (PHMRC) developed stringent diagnostic criteria including laboratory, pathology, and medical imaging findings to identify gold standard deaths in health facilities as well as an enhanced verbal autopsy instrument based on World Health Organization (WHO) standards. A cause list was constructed based on the WHO Global Burden of Disease estimates of the leading causes of death, potential to identify unique signs and symptoms, and the likely existence of sufficient medical technology to ascertain gold standard cases. Blinded verbal autopsies were collected on all gold standard deaths. RESULTS: Over 12,000 verbal autopsies on deaths with gold standard diagnoses were collected (7,836 adults, 2,075 children, 1,629 neonates, and 1,002 stillbirths). Difficulties in finding sufficient cases to meet gold standard criteria as well as problems with misclassification for certain causes meant that the target list of causes for analysis was reduced to 34 for adults, 21 for children, and 10 for neonates, excluding stillbirths. To ensure strict independence for the validation of methods and assessment of comparative performance, 500 test-train datasets were created from the universe of cases, covering a range of cause-specific compositions. CONCLUSIONS: This unique, robust validation dataset will allow scholars to evaluate the performance of different verbal autopsy analytic methods as well as instrument design. This dataset can be used to inform the implementation of verbal autopsies to more reliably ascertain cause of death in national health information systems.

RESUMO

AIM: This study was undertaken to evaluate the impact of grandmultiparity on obstetric outcome in a low resource setting. MATERIAL & METHODS: Two hundred and eighty-two antenatal grandmultiparous women (parity ≥ 4) were compared with consecutive 564 antenatal women with parity 1-3. RESULTS: There were 13 403 deliveries over the study period from Jan 2006-December 2008 at CSMMU, Lucknow. The prevalence of grandmultipara was 2.3%. Grandmultipara were older (P < 0.001) and more commonly from rural areas (P < 0.001) as compared to the control group. The percentage of Muslims among grandmultipara (23.8%) was higher than among controls (16.5%), P < 0.01. Grandmultipara had significantly higher prevalence of anemia (P < 0.001), malpresentation (P = 0.01) and rupture uterus (P < 0.001). Abruptio placenta, placenta previa and obstructed labor were seen more often in grandmultipara, and the difference was statistically significant (P < 0.01 in each group). There was no difference in terms of mode of delivery, sex of newborn or the prevalence of low birthweight (<2.5 kg) babies. Stillbirths were more common in grandmultiparas (P < 0.001). There was one maternal death in the study group. CONCLUSION: Grandmultiparity continues to be of grave concern with an adverse impact on obstetric and perinatal outcome.
