RESUMO
Putting an end to the silent pandemic of unsafe abortion is a major public health concern globally. Adoption of post-abortion contraception is documented as a significant contributor to reduce the number of unintended pregnancies and number of induced abortions. This study aimed at investigating the post abortion contraceptive behavior of Indian women exploring the determinants of post-abortion contraceptive uptake. Retrospective calendar data for 6,862 women aged 15-49 years from fifth round of National Family Health Survey (2019-2021) was used for the study. Multinomial logistic regression method was used to model the determinant factors to post-abortion contraceptive uptake. 72.6% women reported adopting no method of contraception after the abortion procedure. A total of 27.4% women adopted some method of contraception after abortion. 14% women preferred adopting short term modern methods. Women in early reproductive age group which is the most vulnerable group in experiencing unintended pregnancies are less likely to adopt any contraceptive method after abortion. Uptake of post abortion contraception is quite low in India. Effort should be taken in the direction of bringing awareness through provision of targeted contraceptive counselling after abortion.

A BroÌ·nsted acid-driven protocol to access substituted monoarylindene esters, biarylindane esters, and indeno[a]indenones from simple ortho-formylcinnamate esters and external arenes has been revealed. Remarkably, this single-pot process enabled the construction of two, three, and four new C-C bonds in building monoarylindene esters, biarylindane esters, and indeno[a]indenones, respectively, under metal-free and mild reaction parameters via triggering the inactive cinnamate ester moiety. In addition, the present strategy is investigated with widespread substrate scope.
RESUMO
BACKGROUND: Women in their reproductive age have tremendous health implications that affect their health and well-being. Anaemia is an indicator of inadequate dietary intake and poor health. Maternal malnutrition significantly impacts maternal and child health outcomes, increasing the mother's risk of dying during delivery. High-risk fertility behaviour is a barrier to reducing mother and child mortality. This study aims to examine the level of high-risk fertility behaviour and anaemia among ever-married urban Indian women and also examine the linkages between the both. METHODS: Based on the National Family Health Survey's fifth round of data, the study analyzed 44,225 samples of ever-married urban women. Univariate and bivariate analysis and binary logistic regression have been used for the analysis. RESULTS: Findings suggested that more than half (55%) of the urban women were anaemic, and about one-fourth (24%) of women had any high-risk fertility behaviour. Furthermore, the results suggest that 20% of women were more vulnerable to anaemia due to high-risk fertility behaviour. For the specific category, 19% and 28% of women were more likely to be anaemic due to single and multiple high-risk fertility. However, after controlling for sociodemographic factors, the findings showed a statistically significant link between high-risk fertility behaviour and anaemia. As a result, 16% of the women were more likely to be anaemic due to high-risk fertility behaviour, and 16% and 24% were more likely to be anaemic due to single and multiple high-risk fertility behaviour, respectively. CONCLUSIONS: The findings exposed that maternal high-risk fertility behaviour is a significant factor in raising the chance of anaemia in ever-married urban women of reproductive age in forms of the short birth interval, advanced maternal age, and advanced maternal age & higher order. Policy and choice-based family planning techniques should be employed to minimize the high-risk fertility behaviour among Indian urban women. This might aid in the reduction of the malnutrition status of their children.

Herein, a straightforward BroÌ·nsted acids-promoted domino pathway to build substituted benzo[b]carbazoles has been described from easily accessible ortho-formyl (or ortho-acyl) cinnamate esters and indoles. Noticeably, the protocol was amenable to protecting group-free indoles. Notably, this methodology is based on a single-pot regioselective construction of two new C-C bonds and aromatization sequences under mild and metal-free reaction conditions. The mechanistic studies suggested the initial formation of bis-indole substituted intermediate via a dual aromatic substitution with two indole molecules at the carbonyl carbon of ortho-formyl (or ortho-acyl) cinnamate ester followed by intramolecular cyclization and aromatization with exclusion of a second indole molecule. Besides, the efficacy of this approach was also illustrated by scale-up and derivatization reactions, including the photophysical properties study.
RESUMO
BACKGROUND AND AIMS: Gastric varices (GVs) are reported in up to 20% of patients with portal hypertension, and bleeding is often more severe and challenging than esophageal variceal bleeding. Data are limited on prophylaxis of GV bleeding or management in the acute setting, and different techniques are used. This study evaluated outcomes after EUS-guided placement of coils in combination with thrombin to manage GVs. METHODS: We retrospectively reviewed all patients treated with combination EUS-guided therapy with coils and thrombin between October 2015 and February 2020. RESULTS: Twenty patients underwent 33 procedures for GV therapy; 16 of 20 (80%) had type 1 isolated GVs and 4 patients had type 2 gastroesophageal varices. The median follow-up was 842 days (interquartile range [IQR], 483-961). Seventeen patients (85%) had underlying cirrhosis, the most common etiologies being alcohol-related liver disease and nonalcoholic steatohepatitis. The median Child-Pugh score was 6 (IQR, 5-7). In 11 patients (55%), the indication was secondary prophylaxis to prevent recurrent bleeding; in 2 of 20 patients (10%), the bleeding was acute. Technical success was achieved in 19 patients (95%). During follow-up, the obliteration of flow within the varices was achieved in 17 patients (85%). The 6-week survival rate was 100%, and 2 adverse events, recurrent bleeding at day 5 and at day 37, were reported; both recurrent bleeding events were successfully managed endoscopically. CONCLUSIONS: EUS-guided GV obliteration combining coil placement with thrombin, in our experience, was technically safe with good medium-term efficacy. A multicenter randomized controlled trial comparing different treatment strategies is desirable to understand options better.

OBJECTIVE: The present study was carried out to describe contraceptive adoption following pregnancy terminations that resulted in outcomes other than live birth. METHOD: Retrospective calendar data on 31486 women who had experienced a pregnancy loss within the last 60 months prior to the survey date were drawn from a nationally representative dataset. Logistic regression was employed to model the associated factors with contraceptive uptake. RESULTS: Overall, 57.8% reported not adopting any method following the end of the recent pregnancy. There was a significant association between the choice of contraceptive method and timing of adoption. Women with living children were significantly more likely to adopt contraception as compared to women without any child. CONCLUSION: Contraceptive uptake following a non-live birth is considerably low in India. Interventions in reproductive health should focus on provision of different contraceptive methods and counseling emphasizing on effectiveness and correct use of the methods at the end of any pregnancy.

Vitamin D deficiency is a serious issue in developing nations, including India. This study investigates the determinants of vitamin D deficiency among Indian adolescents and assesses their relative importance using dominance analysis. Data from the Comprehensive National Nutrition Survey (CNNS) conducted between 2016 and 2018 were utilized in this study. Vitamin D levels were assessed based on serum 25-hydroxyvitamin D concentration, with a sample size encompassing 13,065 adolescents aged between 10 and 19 years. Backward stepwise multivariate logistic regression was used to identify the correlates of vitamin D deficiency, and the relative importance of these factors was assessed using dominance analysis. The study identified nine predictors that were significantly associated with vitamin D deficiency at a 1% level of significance (α = 0.001). Among these factors, sex was found to be the most significant predictor, with female adolescents being 2.66 (95% CI: 95% CI: 2.39-2.96) times more likely to be vitamin D deficient compared to male adolescents. Lifestyle and behavioral factors, such as "sex," "wealth index," and "place of residence," were more dominant in predicting vitamin D deficiency than biological indicators like "BMI" and "serum creatinine." This underscores the vital role of sunlight exposure in maintaining sufficient vitamin D levels. In summary, this study sheds light on the multifaceted factors contributing to vitamin D deficiency among Indian adolescents, emphasizing the significance of targeted interventions and public health awareness campaigns to mitigate this pressing issue.
RESUMO
Developing mild and effective synthetic strategies for producing significant molecules starting from readily available starting materials is indispensable in organic synthesis. Herein, we present a triflic acid-driven dual cyclization pathway to produce functionalized indeno[2,1-c]chromen-6(7H)-ones from simple 2-formyl (or 2-acyl) cinnamate esters and phenols. Notably, this protocol enabled the construction of two C-C bonds and one C-O bond under metal-free reaction conditions via the activation of the unreactive ester moiety in a single pot. The isolation of intermediate indenol-ester might suggest self-intramolecular cycloaddition by the proximate double bond of the enoate ester with the o-carbonyl moiety, followed by an electrophilic attack with phenol and a subsequent cyclocondensation pathway. In addition, the photophysical properties have also been examined.
RESUMO
AIM: Recent National Family Health Survey results portray striking improvements in most population and health indicators, including fertility, family planning, maternal and child health, gender treatment, household environments, and health insurance coverage of the Pradhan Mantri Jan Arogya Yojana (PM-JAY), with all India resonance. However, the prevalence of any anaemia (< 11 g/dl) among children under age five has exhibited a reversed trajectory in recent years. Therefore, the present study explores key drivers of the reversal of the trend in the prevalence of childhood anaemia between 2015 and2021. METHODS: Data of four rounds of the National Family Health Survey (NFHS) were used to show the overall trend of anaemia among children. However, for the analysis of key drivers of the reversal trend of childhood anaemia, only the recent two rounds (NFHS-4 & NFHS-5) were used. Descriptive, bivariate multivariable analysis and Fairlie decomposition model were used to explore the drivers of the reversal of the trend in childhood anaemia. RESULTS: During the past two decades, India has seen a decline in the prevalence of childhood anaemia (NFHS-2 to NFHS-4). However, a reversal of trend was observed recently. The prevalence of anaemia among children aged 6-59 months increased from 59 percent in NFHS-4 to 67 percent in NFHS-5. In addition, the prevalence of mild anaemia increased from 23.3 percent in NFHS-2 to 28.7 percent in NFHS-5. However, the prevalence of moderate and severe anaemia declined considerably from NFHS-2 (40 percent and 4.1 percent) to NFHS-4 (28.7 percent and 1.6 percent), but showed an increase in the prevalence in NFHS-5 (36.3 percent and 2.2 percent). Among others, mothers' educational attainment, anaemia status and socio-economic status emerge as the key drivers of the change in the prevalence of childhood anaemia. CONCLUSION: These findings may have vital implications for the ongoing Anaemia Mukt Bharat Programme, one of the government's dream projects in India.

BACKGROUND AND AIMS: Bleeding from parastomal varices causes significant morbidity and mortality. Treatment options are limited, particularly in high-risk patients with significant underlying liver disease and other comorbidities. The use of EUS-guided embolisation coils combined with thrombin injection in gastric varices has been shown to be safe and effective. Our institution has applied the same technique to the treatment of parastomal varices. METHODS: A retrospective review was performed of 37 procedures on 24 patients to assess efficacy and safety of EUS-guided injection of thrombin, with or without embolisation coils for treatment of bleeding parastomal varices. All patients had been discussed in a multidisciplinary team meeting, and correction of portal hypertension was deemed to be contraindicated. Rebleeding was defined as stomal bleeding that required hospital admission or transfusion. RESULTS: All patients had significant parastomal bleeding at the time of referral. 100% technical success rate was achieved. 70.8% of patients had no further significant bleeding in the follow-up period (median 26.2 months) following one procedure. 1-year rebleed-free survival was 80.8% following first procedure. 7 patients (29.1%) had repeat procedures. There was no significant difference in rebleed-free survival following repeat procedures. Higher age was associated with higher risk of rebleeding. No major procedure-related complications were identified. CONCLUSIONS: EUS-guided thrombin injection, with or without embolisation coils, is a safe and effective technique for the treatment of bleeding parastomal varices, particularly for patients for whom correction of portal venous hypertension is contraindicated.

In recent years, developing and developed countries are witnessing delayed childbearing among women contributing to the overall decline in fertility rates. The age at which a woman has her last child impacts maternal and child health, especially in a country with high maternal and perinatal mortality rates. This study aims to investigate the trends of age at the last birth among Indian women and to identify the potential factors contributing towards higher maternal age. The present study uses the data from five consecutive rounds (1992-1993, 1998-1999, 2004-2005, 2015-2016, and 2019-2021) of the National Family Health Survey (NFHS). We have used descriptive statistics, bivariate, Cox proportional hazard regression analysis, multiple classification analysis (MCA), Kaplan-Meier curve, life table survival analysis, hierarchical clustered heat map, multivariate decomposition analysis (MDA) and geospatial mapping to fulfill the objective of the study. Results show that the proportion of women with age at last birth before reaching the age of 30 years was less than half (nearly 35%) during NFHS-I while during NFHS-V proportion becomes more than half and reaches 64.3% among 40-49 years women. Within three decades (1992-2021) there has been a decline of 15.8% in median age at last birth among women aged 40-49 years. Additionally, the highest percentage decline in predicted mean age at last birth was noted among individuals from rural area (10.7%, 3.3 years), Hindu religion (10.8%, 3.3 years), poor wealth quantile (12.5%, 4.0 years) and those with mass media exposure (10.6%, 3.2 years) from NFHS-I (1992-1993) to NFHS-V (2019-2021). Although there exists the need to delay age at first childbirth, the age at last childbirth also plays an important role in women's and child health status. Hence, it is important to address the healthcare needs of those delaying their childbirth.

The disproportionate share of contraceptive use by women makes family planning services women-centric in India. The meagre and declining share of male-based contraceptive use, along with the overwhelming prevalence of female sterilization, has its underpinning in the lack of emphasis on fertility regulation with the use of temporary methods. The recent trends in the share of contraceptive choices not only contest the most touted cafeteria approach but also serves counter to the National Health Policy target of increasing vasectomy prevalence. Hence an inspection of trends in vasectomy may help in course correction needed to realise NHP targets.
RESUMO
INTRODUCTION: Reproductive health events have changed fertility and family planning needs, depicting the changing life patterns of women and the population to which they belong. Understanding the pattern at which these events occur helps in understanding the fertility pattern, family formation and the idea about health essential needs for women. This paper attempts to see the variation in reproductive events (first cohabitation, first sex and first birth) over three decades and also to see potential contributing factors among the reproductive age group of women using secondary data from Data Source: All rounds of the National Family Health Survey (1992-93 to 2019-2021) have been utilized. METHODS AND RESULTS: Cox Proportional Hazard Model illustrates that all regions have initiated their first birth later than women who belong to the east region similar pattern has been obtained for first cohabitation and first sex except for the central region. Multiple Classification Analysis (MCA) depicts the increasing pattern in the predicted mean age at first cohabitation, sex and birth for all demographic characteristics; the highest increment was found in SC women, Uneducated women and Muslim women. Kaplan Meier Curve demonstrates that women with no education, primary or secondary education are shifting towards higher educated women. Most importantly, the results of the multivariate decomposition analysis (MDA) revealed that education played the largest contribution among the compositional factors in the overall increase in mean ages at key reproductive events. CONCLUSIONS: Though reproductive health has long been essential in women's lives, they are still very confined to specific domains. Over time the government has formulated several proper legislative measures relating to various domains of reproductive events. However, given that the large size and heterogeneity in social and cultural norms result in changing ideas and choices regarding the initiation of reproductive events, national policy formulation needs to be improved or amended.

Reproductive health and well-being of a woman are associated with factors such as menarche, first marriage, first sex, first birth, and menopause. The beginning of these events also brings about significant changes in women's lives. Despite marrying early being acknowledged as a detrimental and discriminatory socio-cultural global practice, a huge proportion of girls are being married at an early age, often detrimental to maternal and child health. Adding to the current national debate for the revision of the minimum age at marriage for girls from 18 to 21 years it becomes important to understand the past scenario and current situation of age at marriage in India. In this study, first five rounds of the National Family Health Survey (NFHS) have been used as a data source. Cox Proportional Hazard Model, Multiple Classification Analysis (MCA), Kaplan Meier Curve, Life table survival analysis, hierarchical clustered heat map, Multivariate Decomposition Analysis (MDA), and geospatial mapping were used to fulfill the objective of the study. The results showed that almost 65.9% of women got married before reaching the age of 18 years in the year 1992-93 which reduced to 23.2% among women aged 20-24 years in 2019-21. Region, respondent's level of education, caste, religion, wealth, and mass media exposure were significantly associated with the age at first marriage. The hazard of age at marriage declined significantly with higher educational attainment [higher education- AHR:0.37; CI:0.36 to 0.37], improving household wealth [richest wealth- AHR:0.91; CI:0.90 to 0.91], and mass media exposure [AHR:0.96; CI:0.95 to 0.96]. Since, the age at marriage has a substantial impact on fertility pattern and has a strong association with maternal & child health, policies regarding improving the age at marriage and better enforcement of the concerned laws are required to meet the SDG targets.
RESUMO
India has a very high prevalence of female sterilisation compared to other countries in the world, with a prevailing situation of very low level of information about contraceptive options given to women. It is well established in demographic research that, there exists a strong association between knowledge of contraceptive methods and type of contraception chosen. Present study uses data from 3 consecutive rounds of National Family Health Survey (3, 4 & 5). The sample contains currently married women who started using the current method 5 years prior to each round of survey. Multilevel Logistic Regression and Fairlie Decomposition Model are used to analyse the effect of information given to respondents and decision-making power regarding contraceptive methods on choice of female sterilisation. Women, who are informed about available methods, have lower chance (45.8%, 37.5% & 40% for NFHS 3, 4 & 5 respectively) to opt for sterilisation after controlling all other factors. If woman is the sole decision maker for contraceptive choice, the chance of sterilisation reduces than cases where decision is taken only by husband or jointly. Information about other methods also contributes towards reducing the chance of female sterilisation over the time. Information about contraceptive methods is found to be a major factor in controlling choice of temporary or permanent method. Thus, major focus for the policy makers should be to make information regarding contraceptives more accessible for women.

BACKGROUND: Vitamin D deficiency has been found to associated with numerous skeletal and non-skeletal diseases including Diabetes Mellitus. Insulin Resistance (IR) is considered as one of the primary reasons of Type-2 Diabetes Mellitus (T2DM). The association between vitamin D deficiency and IR has been extensively explore in previous studies, but none of them focused on Indian adolescents, and none of them used the TyG index as IR marker. Hence, this population-based cross-sectional study investigates the relationship between insulin resistance (IR) assessed using the Triglycerides Glucose Index (TyG index) and vitamin D measured by serum 25-hydroxyvitamin-D (25(OH)D). METHODS: For this study, we utilized data from the Comprehensive National Nutrition Survey (CNNS, 2016-18). The study is based on a sample size of 10,167 adolescents aged 10-19 years. The TyG index cut-off value of 4.65 was used to classify IR. We examined associations between the TyG index and serum 25(OH)D using multiple linear regression models adjusted for potential confounders. Odds of Insulin Resistance among vitamin D deficient/insufficient adolescents were assessed using multivariable logistic regression. RESULTS: A significant negative association was found between serum 25(OH)D and the TyG index, where a 10% increase in serum 25(OH)D was associated with 0.56 (95% CI = -0.67, -0.45) unit decrement in the TyG index. The odds of having IR were 90% higher among vitamin D deficient adolescents (OR: 1.90; 95% CI = 1.62-2.23) compared to adolescents with adequate levels of vitamin D. The association between vitamin D deficiency and IR was independent of sex; in other words, the association between vitamin D and IR was significant in both the sexes. CONCLUSION: Independent of sex, this study found a significant inverse association between vitamin D and insulin resistance in Indian adolescents. The findings of this study highlight the utility of TyG index and the importance of vitamin D in lowering the risk of T2DM in future generations of the country.
RESUMO
BACKGROUND: In a patriarchal society, women often keep their use of contraceptives secret in order to meet their reproductive goals and satisfy their reproductive preferences. Nevertheless, to our knowledge, women's covert contraceptive use and its association with husband's gender attitude have not been studied in the Indian settings. The present study estimates the extent of covert modern contraceptive use (CCU) among women and its linkage with husbands' gender attitudes in India. METHODS: The study is based on fecund and monogamous couples using modern, reversible contraceptive methods. The numbers of such couples were 4,825 and 7,824 in the national family health surveys 2005-06 and 2015-16 respectively. The outcome variable in the study was CCU, while the independent variables were husband's gender attitude, women's education, freedom of mobility, freedom to spend money independently, surviving number of children, concordance regarding additional children, couple-level information such as age and educational gap between spouses, and some socioeconomic status (SES) variables. We used latent class analysis to measure the gender attitude and used bivariate descriptive analysis and multivariate binary logistic regression to assess the linkages between husband's gender attitude and CCU. RESULTS: This study found that the prevalence of CCU increased from 15% in 2005-06 to 27% in 2015-16. In both the time periods, contraceptive pills were the most preferred covert method, followed by intrauterine device (IUD). The results of the multivariate logistic regression show that women with husbands of moderate and low egalitarian gender attitudes were, respectively, 50% and 40% more likely to hide their contraceptive use than those with husbands of a high gender attitude. Women's education, wealth index, number of living children, and region of residence were also found to be significantly associated with CCU. CONCLUSION: The study reveals that husband's low egalitarian gender attitude can be a potential barrier between spouses, preventing them from opening up about their fertility preferences and contraceptive needs to each other. A couple-oriented approach to family planning is needed so that both members of a couple can satisfy their fertility desires and preferences eventually.

OBJECTIVES: The transition to small family size is at an advanced phase in India, with a national TFR of 2.2 in 2015-16. This paper examines the roles of four key determinants of fertility-marriage, contraception, abortion and postpartum infecundability-for India, all 29 states and population subgroups. METHODS: Data from the most recent available national survey, the National Family Health Survey, conducted in 2015-16, were used. The Bongaarts proximate determinants model was used to quantify the roles of the four key factors that largely determine fertility. Methodological contributions of this analysis are: adaptations of the model to the Indian context; measurement of the role of abortion; and provision of estimates for sub-groups nationally and by state: age, education, residence, wealth status and caste. RESULTS: Nationally, marriage is the most important determinant of the reduction in fertility from the biological maximum, contributing 36%, followed by contraception and abortion, contributing 24% and 23% respectively, and post-partum infecundability contributed 16%. This national pattern of contributions characterizes most states and subgroups. Abortion makes a larger contribution than contraception among young women and better educated women. Findings suggest that sterility and infertility play a greater than average role in Southern states; marriage practices in some Northeastern states; and male migration for less-educated women. The absence of stronger relationships between the key proximate fertility determinants and geography or socio-economic status suggests that as family size declined, the role of these determinants is increasingly homogenous. CONCLUSIONS: Findings argue for improvements across all states and subgroups, in provision of contraceptive care and safe abortion services, given the importance of these mechanisms for implementing fertility preferences. In-depth studies are needed to identify policy and program needs that depend on the barriers and vulnerabilities that exist in specific areas and population groups.

This report illustrates BF3·OEt2 promoted intramolecular cascade cycloaromatization of 1,7-ynones toward synthesizing structurally diverse benzofluorene scaffolds. Remarkably, the present protocol promotes the formation of two consecutive C-C bonds intramolecularly and undergoes aromatization under mild reaction conditions to afford the tetracyclic benzo[a]fluorene frameworks. Besides, the formation of indenes was observed when 1-bromo-2-iodoarenes are relatively more electron-rich when compared with the one originating from the terminal arylacetylenes, under controlled conditions, wherein triple bond polarity has been just reversed due to the change of electronic effects exerted by the strong +M group of 1-bromo-2-iodoarenes, which is in conjugation to the connected triple bond. The same concept to generate indenes has also been extended by using aliphatic alkyne tethered ynones. Further, it was noticed that 1,7-ynones bearing the more electron-rich 1-bromo-2-iodoarenes than the arene ring arriving from the terminal arylacetylenes lead to benzo[b]fluorenes, under thermodynamic conditions, instead of delivering the benzo[a]fluorenes. In addition, this method features metal-free conditions, easily accessible starting materials, operational simplicity, gram-scale synthesis, and a wide range of substrate scopes.
