Response of Iron and Cadmium on Yield and Yield Components of Rice and Translocation in Grain: Health Risk Estimation

Rice consumption is a major dietary source of Cd and poses a potential threat to human health. The aims of this study were to examine the influence of Fe and Cd application on yield and yield components, dynamics of Cd in pore water, translocation factors, daily dietary intake, and estimation of human health risks. A pot experiment was performed under glasshouse conditions where rice cultivars (Langi and Quest) were cultivated in two dissimilar soils under different levels of Cd (0, 1.0, and 3.0 mg kg−1) and Fe (0, 1.0, and 2.0 g kg−1). The results showed that variation in two rice cultivars in terms of yield and yield-related components was dose dependent. Cadmium concentration in soil pore water was decreased over time and increased with increasing Cd levels but decreased with Fe application. Translocation factors (TFs) from root to straw (TFroot-straw) or straw to husk (TFstraw-husk) were higher than root to grain (TFroot-grain) or straw to grain (TFstraw-grain). The Quest cultivar had 20% lower Cd than the Langi cultivar. Application of Fe at the rate of 1 and 2 g kg−1 soil reduced Cd by 23 and 46%, respectively. Average daily intake (ADI) of Cd exceeded the permissible limit (5.8 × 10−3 mg −1 kg−1 bw per week) when rice plant subjected 1 and 3 mg kg−1 Cd stress with or without Fe application. Results also indicated that ADI value was lower in the Quest cultivar as compared to the Langi cultivar. Estimation of human health risk revealed that the non-carcinogenic risks (HQ > 1) and carcinogenic risks (CR > 1.0 × 10−4) increased with increasing Cd levels in the soil. The application of Fe decreased the human health risks from rice consumption which is more pronounced in Fe 2.0 than in Fe1.0 treatments. The rice cultivar grown in soil-1 (pH 4.6) showed the highest health risks as compared to soil-2 (pH 6.6) and the Quest cultivar had lower health risks than the Langi cultivar

Exploring the factors contributing to increase in facility child births in Bangladesh between 2004 and 2017-2018

Although Bangladesh has gained rapid improvement in births at health facilities, yet far behind to achieve the SDG target. Assessing the contribution of factors in increased use of delivery at facilities are important to demonstrate. To explore the determinants and their contribution in explaining increased use of facility child births in Bangladesh. Reproductive-aged women (15-49 years) of Bangladesh. We used the latest five rounds (2004, 2007, 2011, 2014, 2017-2018) of Bangladesh Demographic and Health Surveys (BDHSs). The regression based classical decomposition approach has been used to explore the determinants and their contribution in explaining the increased use of facility child birth. A sample of 26,686 reproductive-aged women were included in the analysis, 32.90% (8780) from the urban and 67.10% (17,906) from the rural area. We observed a 2.4-fold increase in delivery at facilities from 2004 to 2017-2018, in rural areas it is more than three times higher than the urban areas. The change in mean delivery at facilities is about 1.8 whereas, the predicted change is 1.4. In our full sample model antenatal care visits contribute the largest predicted change of 22.3%, wealth and education contributes 17.3% and 15.3% respectively. For the rural area health indicator (prenatal doctor visit) is the largest drivers contributing 42.7% of the predicted change, hereafter education, demography and wealth. However, in urban area education and health contributed equally 32.0% of the change followed by demography (26.3%) and wealth (9.7%). Demographic variables (maternal BMI, birth order, age at marriage) contributing more than two-thirds (41.2%) of the predicted change in the model without the health variables. All models showed more than 60.0% predictive power. Health sector interventions should focus both coverage and quality of maternal health care services to sustain steady improvements in child birth facilities. [Abstract copyright: © 2023 The Authors.

Systematic review and meta-Analysis of global birth prevalence of clubfoot: A study protocol

IntroductionClubfoot is a common congenital birth defect, with an average prevalence of approximately 1 per 1000 live births, although this rate is reported to vary among different countries around the world. If it remains untreated, clubfoot causes permanent disability, limits educational and employment opportunities, and personal growth. The aim of this systematic review and meta-analysis is to estimate the global birth prevalence of congenital clubfoot.Methods and analysisElectronic databases including MEDLINE, Cumulative Index to Nursing and Allied Health Literature (CINAHL), Embase, Global Health, Latin American &amp; Caribben Health Science Literature (LILACS), Maternity and Infant Care, Web of Science, Scopus and Google Scholar will be searched for observational studies based on predefined criteria and only in English language from inception of database in 1946 to 10 November 2017. A standard data extraction form will be used to extract relevant information from included studies. The Joanna Briggs Institute appraisal checklist will be used to assess the overall quality of studies reporting prevalence. All included studies will be assessed for risk of bias using a tool developed specifically for prevalence studies. Forest plots will be created to understand the overall random effects of pooled estimates with 95% CIs. An I2test will be done for heterogeneity of the results (P&gt;0.05), and to identify the source of heterogeneity across studies, subgroup or meta-regression will be used to assess the contribution of each variable to the overall heterogeneity. A funnel plot will be used to identify reporting bias, and sensitivity analysis will be used to assess the impact of methodological quality, study design, sample size and the impact of missing data.Ethics and disseminationThis review will be conducted completely based on published data, so approval from an ethics committee or written consent will not be required. The results will be disseminated through a peer-reviewed publication and relevant conference presentations.PROSPERO registration numberCRD42016041922.</jats:sec

Knowledge and involvement of husbands in maternal and newborn health in rural Bangladesh

Abstract Background Access to skilled health services during pregnancy, childbirth and postnatal period for obstetric care is one of the strongest determinants of maternal and newborn health (MNH) outcomes. In many countries, husbands are key decision-makers in households, effectively determining women’s access to health services. We examined husbands’ knowledge and involvement regarding MNH issues in rural Bangladesh, and how their involvement is related to women receiving MNH services from trained providers. Methods We conducted a cross-sectional survey in two rural sub-districts of Bangladesh in 2014 adopting a stratified cluster sampling technique. Women with a recent birth history and their husbands were interviewed separately with a structured questionnaire. A total of 317 wife-husband dyads were interviewed. The associations between husbands accompanying their wives as explanatory variables and utilization of skilled services as outcome variables were assessed using multiple logistic regression analyses. Results In terms of MNH knowledge, two-thirds of husbands were aware that women have special rights related to pregnancy and childbirth and one-quarter could mention three or more pregnancy-, birth- and postpartum-related danger signs. With regard to MNH practice, approximately three-quarters of husbands discussed birth preparedness and complication readiness with their wives. Only 12% and 21% were involved in identifying a potential blood donor and arranging transportation, respectively. Among women who attended antenatal care (ANC), 47% were accompanied by their husbands. Around half of the husbands were present at the birthplace during birth. Of the 22% women who received postpartum care (PNC), 67% were accompanied by their husbands. Husbands accompanying their wives was positively associated with women receiving ANC from a medically trained provider (AOR 4.5, p < .01), birth at a health facility (AOR 1.5, p < .05), receiving PNC from a medically trained provider (AOR 48.8, p < .01) and seeking care from medically trained providers for obstetric complications (AOR 3.0, p < 0.5). Conclusion Husbands accompanying women when receiving health services is positively correlated with women’s use of skilled MNH services. Special initiatives should be taken for encouraging husbands to accompany their wives while availing MNH services. These initiatives should aim to increase men’s awareness regarding MNH issues, but should not be limited to this

Arsenic in Peruvian rice cultivated in the major rice growing region of Tumbes river basin

Arsenic (As) exposure from surface and groundwater in Peru is being recognised as a 16 potential threat but there are limited studies on As in the food-chain and none on As in 17 Peruvian rice. In this study, we have determined the As content in rice cultivated in the 18 Tumbes river basin located in the northern province of Peru, an area known for extensive rice 19 cultivation. We collected rice and soil samples from agricultural fields, soil was collected 20 using grid sampling technique while rice was collected from the heaps of harvested crop 21 placed across the fields. The average total As concentration in rice was 167.94 ± 71 μg kg-1 22 (n=29; range 68.39-345.31 μg kg-1). While the rice As levels were not highly elevated, the As 23 content of few samples (n=7) greater than 200 μg kg-1 could contribute negatively to human health upon chronic exposure. Average concentration of As in soil was 8.63 ± 7.8 mg kg-1 25 (n=30) and soil to grain transfer factor was 0.025 ± 0.018 for 12 matched samples. Compared 26 to our previous pilot study in 2006 (samples collected from the same agricultural fields but 27 not from exact locations) there was a 41% decrease in As soil concentration in this study. 28 Rice samples collected in 2006 (n=5) had a mean concentration of 420 ± 109 μg kg-1. Our 29 data provides a baseline of rice grain As concentrations in Peruvian province of Tumbes and 30 warrants further studies on factors affecting uptake of As by the rice varieties cultivated in 31 Peru and any potential human health risks

A community-based cluster randomised controlled trial in rural Bangladesh to evaluate the impact of the use of iron-folic acid supplements early in pregnancy on the risk of neonatal mortality: The Shonjibon trial

Abstract Background Iron-deficiency is the most common nutritional deficiency globally. Due to the high iron requirements for pregnancy, it is highly prevalent and severe in pregnant women. There is strong evidence that maternal iron deficiency anaemia increases the risk of adverse perinatal outcomes. However, most of the evidence is from observational epidemiological studies except for a very few randomised controlled trials. IFA supplements have also been found to reduce the preterm delivery rate and neonatal mortality attributable to prematurity and birth asphyxia. These results combined indicate that IFA supplements in populations of iron-deficient pregnant women could lead to a decrease in the number of neonatal deaths mediated by reduced rates of preterm delivery. In this paper, we describe the protocol of a community-based cluster randomised controlled trial that aims to evaluate the impact of maternal antenatal IFA supplements on perinatal outcomes. Methods/design The effect of the early use of iron-folic acid supplements on neonatal mortality will be examined using a community based, cluster randomised controlled trial in five districts with 30,000 live births. In intervention clusters trained BRAC village volunteers will identify pregnant women & provide iron-folic acid supplements. Groundwater iron levels will be measured in all study households using a validated test kit. The analysis will follow the intention to treat principle. We will compare neonatal mortality rates & their 95% confidence intervals adjusted for clustering between treatment groups in each groundwater iron-level group. Cox proportional hazards mixed models will be used for mortality outcomes & will include groundwater iron level as an interaction term in the mortality model. Discussion This paper aims to describe the study protocol of a community based randomised controlled trial evaluating the impact of the use of iron-folic acid supplements early in pregnancy on the risk of neonatal mortality. This study is critical because it will determine if antenatal IFA supplements commenced in the first trimester of pregnancy, rather than later, will significantly reduce neonatal deaths in the first month of life, and if this approach is cost-effective. Trial registration This trial has been registered with the Australian New Zealand Clinical Trials Registry (ANZCTR) on 31 May 2012. The registration ID is ACTRN12612000588897

Problematic internet use in Bangladeshi students: the role of socio-demographic factors, depression, anxiety, and stress

Problematic Internet Use (PIU) has become a concern for public mental health across the globe. However, there are few studies assessing PIU in Bangladesh. The present cross-sectional study estimated the prevalence rate of PIU and its associated risk factors among 405 university students in Bangladesh between June and July 2018. The measures included sociodemographic questions, internet and health-related variables, the Internet Addiction Test (IAT) and the Depression, Anxiety and Stress Scale (DASS-21). The prevalence of PIU was 32.6% among the respondents (cut-off score of ≥50 on the IAT). The prevalence of PIU was higher in males in comparison to females, although the difference was not statistically significant. Internet-related variables and psychiatric comorbidities were positively associated with PIU. From the unadjusted model, more frequent use of the internet and more time spent on the internet were identified as strong predictors of PIU, whereas the adjusted model showed depressive symptoms and stress only as strong predictors of PIU. It is hoped this preliminary study will facilitate further study on PIU along with other psychiatric disorders in Bangladesh

Investigating the prevalence and associated factors of depression, anxiety, and loneliness among people with type-2 diabetes in Bangladesh: a community-based study

Diabetes mellitus is a major worldwide health concern. Diabetes has been associated with a number of adverse mental health conditions including depression, anxiety, and loneliness that can negatively impact diabetes outcomes. This study aimed to investigate factors associated with depression, anxiety, and loneliness in people, in the community, suffering with diabetes in Bangladesh. A cross-sectional study was conducted with 600 people with type-2 diabetes (54.83% females; mean age: 52.70 ± 11.56 years) between July and September 2022. Purposive sampling method was used to recruit the participants. A validated semi-structured questionnaire was used to collect demographic and other data. Depression, anxiety, and loneliness were measured using the PHQ-9, GAD-7, and UCLA Loneliness scale, respectively. Bivariate and multivariable linear regression analyses were conducted to ascertain factors that were significantly associated with these mental health conditions. The prevalence of depression, anxiety, and loneliness was 31.17%, 21.83%, and 28.00%, respectively. A lack of formal education, and not taking part in physical activities were significantly associated with all three mental health states. Duration of diabetes and being on medication for high cholesterol were also associated with depression and anxiety. Older age and being widowed were significantly associated with loneliness. This study found that depression, anxiety, and loneliness are prevalent among Bangladeshi people with diabetes, with certain sociodemographic and diabetes-related factors associated with increased risk. The findings emphasize the need for targeted interventions to people within the communities, at grassroot levels in order to improve reduce health inequality, and improve the mental health of people living with diabetes.</p

Polypoid gall bladder lesions: Is it necessary for immediate surgery?

Ultrasonographic study of hepatobiliary system was done in 481 patients with acute right hypochondriac pain to find out any pathology in hepatobiliary system. A total of 57 patients with polypoid lesions in gall bladder were diagnosed and underwent extensive follow-up. In 31 patients, who underwent surgery, the histological findings were cholesterol polyp/cholesterosis (n=14), cholesterosis with fibrous displasia of gall bladder (n=7), adenomyomatosis (n=3), hyperplastic cholecystosis (n=5) and adenocarcinoma (n=2). Remaining 26 patients were under follow-up up to 18 months from first diagnosis. Though most of the polyps diagnosed on ultrasound appeared to be benign without any risk of malignant transformation, it, however, may be recommended to go for surgery in a persistent symptomatic patient
