Abstract Child marriage negatively affects women’s socio-economic empowerment, particularly in education and employment. This study aimed to explore women’ perspectives on the timing of their marriages, considering their educational and employment status at the time. It also sought to identify factors influencing early married women’s perception of their marriages as timely. We analyzed both quantitative and qualitative data. The quantitative data included a sample of 5,596 women aged 15–24 from the 2017/18 Bangladesh Demographic and Health Survey. Additionally, we collected qualitative data through six in-depth interviews, two focus group discussions, and 13 key informant interviews. We used a multilevel mixed-effects Poisson regression model to examine the relationship between women’s formal employment, education, and child marriage. Thematic analysis was employed for the qualitative data. Around 62% of the total women analysed reported their married occurred early with the mean age at marriage was 15.2 years. Approximately 55% of the total early married women believed their marriages occurred at the right time, especially among those who were employed at the time of their marriage. Among this subset, we also noticed a higher likelihood of discontinuing work and education following marriage. Qualitative findings revealed reasons behind this perception, such as escaping poverty, safety concerns, limited job prospects, and the impact of non-marital relationship and societal norms. While many early-married women perceived their marriage as timely, particularly those initially employed, this decision often coincides with a subsequent withdrawal from work and education. This underscores the pressing need for policies and programs aimed at educating women about the legal age for marriage and the negative consequences associated with early marriage while also equipping them with knowledge and resources for informed decision-making.

Abstract Background COVID-19 vaccine uptake among individuals with disabilities is crucial for safeguarding their health and well-being. However, the extent of vaccine uptake among this group remains largely unknown in low- and middle-income countries. This study aims to assess the COVID-19 vaccine uptake among persons with functional difficulty, disability and/or comorbidity in Bangladesh and their associated factors. Methods Data from 9,370 respondents extracted from the 2021 National Household Survey on Persons with Disability were analysed. The outcome variable was the uptake of at least one dose of the COVID-19 vaccine (yes, no). Key explanatory variables included the presence of disability (yes, no), comorbidity (yes, no), and both comorbidity and disability (yes, no) among persons with functional difficulty. The relationship between the outcome and explanatory variables was determined using mixed-effects multilevel logistic regressions adjusted for covariates. Results The overall uptake of at least one dose of the COVID-19 vaccine among persons with functional difficulty was 57.37%, among persons with functional difficulty and disability was 48.63% and among persons with functional difficulty and single (57.85%) or multi-comorbidity (60.37%). Compared to the respondents with functional difficulty only, the adjusted odds ratio (aOR) of not receiving any dose of the COVID-19 vaccine for individuals with both functional difficulty and disability was 1.37 (95% CI, 1.22–1.53), and for individuals with functional difficulty, disability and one or more comorbid conditions was 1.30 (95% CI, 1.15–1.47). The aOR of receiving at least one dose of the COVID-19 vaccine among individuals with functional difficulty and one or more comorbid conditions was significantly higher than among those with functional difficulty only. Conclusion In Bangladesh, COVID-19 vaccine uptake was relatively low among individuals with disabilities. The existing COVID-19 vaccine rollout programs and similar future programs should prioritise individuals with disabilities and include targeted strategies to reach them.

Abstract This study investigates the potential of renewable energy sources to address the growing energy demands of developing nations while ensuring environmental sustainability. Here, a model-based analysis to assess the feasibility of utilizing rice straw pyrolysis as a renewable energy source is investigated. The thermogravimetric analysis identified the optimal temperature range for pyrolysis (230–400 °C) and the Coats–Redfern model was employed for kinetic analysis. Diffusion models, particularly D3, exhibited the best fit with an activation energy of 16–18 kJ/mol. Thermodynamic analysis confirmed the endothermic nature of the process, with positive enthalpy and negative entropy changes indicating an increase in energy and a more ordered product. These findings suggest that rice straw pyrolysis holds promise as a viable renewable energy option. This study contributes to understanding the rice straw pyrolysis mechanism which could be helpful for its effective utilization at commercial scale.

Abstract Background Sustainable Development Goal (SDG) 3.7 aims to ensure universal access to sexual and reproductive healthcare services, where antenatal care (ANC) is a core component. This study aimed to examine the influence of health facility availability and readiness on the uptake of four or more ANC visits in Bangladesh. Methods The 2017/18 Bangladesh Demographic and Health Survey data were linked with the 2017 Health Facility Survey and analyzed in this study. The associations of health facility-level factors with the recommended number of ANC uptakes were determined. A multilevel mixed-effect logistic regression model was used to determine the association, adjusting for potential confounders. Results Nearly 44% of mothers reported four or more ANC uptakes, with significant variations across several areas in Bangladesh. The average distance of mothers' homes from the nearest health facilities was 6.36 km, higher in Sylhet division (8.25 km) and lower in Dhaka division (4.45 km). The overall uptake of the recommended number of ANC visits was positively associated with higher scores for the management (adjusted odds ratio (aOR) 1.85; 95% CI, 1.16–2.82) and infrastructure (aOR, 1.59; 95% CI, 1.09–2.19) of health facilities closest to mothers' homes. The odds of using the recommended number of ANC in mothers increased by 3.02 (95% CI, 2.01–4.19) and 2.36 (95% CI, 2.09–3.16) folds for each unit increase in the availability and readiness scores to provide ANC services at the closest health facilities, respectively. Every kilometer increase in the average regional-level distance between mothers' homes and the nearest health facilities reduced the likelihood of receiving the recommended number of ANC visits by nearly 42% (aOR, 0.58, 95% CI, 0.42–0.74). Conclusion The availability of healthcare facilities close to residence, as well as their improved management, infrastructure, and readiness to provide ANC, plays a crucial role in increasing ANC services uptake. Policies and programs should prioritize increasing the availability, accessibility, and readiness of health facilities to provide ANC services.

The liver is one of the most essential organs in the body, which helps with metabolism and keeping the body healthy. Successful treatments and better patient outcomes depend on early and correct Liver Disease (LD) diagnosis and identification. This study proposes a system for predicting the LD by combining the techniques of Machine Learning (ML) algorithms that include the Decision Tree, Random Forest, Extra Tree Classifier (ETC), LightGBM, and Adaboost, with the Tree-Structured Parzen Estimator (TPE) method for hyperparameter tuning. No previous literature research has utilized ML algorithms with TPE to predict LD. For this research, the Indian Liver Patients’ Dataset with 583 instances and 11 attributes was used. In the pre-processing of the data, techniques such as upsampling have been utilized to address the class imbalance problem. Normalization has been employed to scale the dataset, and feature selection has been applied to choose important features. The proposed model has been analyzed and compared using a 10-fold cross-validation process, with various evaluation metrics including accuracy, precision, recall, and F1-score. The model proposed in this study achieved the best level of accuracy while employing the ETC with the TPE approach, with a recorded accuracy of 95.8%.

Background: Depression, anxiety and stress among university students present a growing global challenge. This study aims to explore the prevalence of depression, anxiety, and stress and identifying their associated factors among university students in Bangladesh. Methods: We analyzed data of 738 university students collected through a cross-sectional survey. Outcome variables considered were depression, anxiety, and stress levels. Explanatory variables considered were several socio-demographic characteristics. Multinomial logistic regression analysis was employed to explore the association of the outcome variables with explanatory variables. Results: We found a notable prevalence of moderate to severe levels of depression, anxiety, and stress among university students in Bangladesh, ranging from 25 % to 71 %. Among students from extended families, there was a 32 % lower likelihood of experiencing moderate depression (relative risk ratio [RRR], 0.68; 95 % confidence interval [CI], 0.47–0.97) and a 35 % lower likelihood of experiencing stress (RRR, 0.65; 95 % CI, 0.44–0.97) compared to their counterparts without depression and stress. Furthermore, students enrolled in the business faculty reported a significantly higher likelihood of stress, with a 2.28 times greater odds (95 % CI, 1.32–3.93) compared to students in the Science and Engineering faculty. Conclusion: This study underscores the pressing necessity for tailored interventions to address the elevated prevalence of depression, anxiety, and stress among university students in Bangladesh. The findings accentuate the importance of recognizing diverse risk factors and implementing mental health support programs.

Abstract Background Early marriage is highly prevalent in Bangladesh. It is linked with a range of adverse outcomes, including maternal and child mortality. However, research on regional variations and factors associated with early marriage is scarce in Bangladesh. This study aimed to explore the geographical variations and predictors of early marriage in Bangladesh. Methods Data of women aged 20–24 in the Bangladesh Demographic and Health Survey 2017–18 were analysed. The occurrence of early marriage was the outcome variable. Explanatory variables were several individual-, household- and community-level factors. Geographical hot spots and cold spots of early marriage were first determined using Global Moran’s I statistic. Multilevel mixed-effect Poisson regression was used to determine the association of early marriage with individual-, household-, and community-level factors. Results Almost 59% of women aged 20–24 reported they were married before reached 18. The hotspots of early marriage were mainly concentrated in Rajshahi, Rangpur and Barishal, and the cold spots were in Sylhet and Chattogram divisions. The prevalence of early marriage was lower among higher educated (adjusted prevalence ratio (aPR): 0.45; 95% CI: 0.40, 0.52), and non-Muslim women (aPR: 0.89; 95% CI: 0.79, 0.99) than their counterparts. Higher community-level poverty was significantly associated with early marriage (aPR, 1.16; 95% CI: 1.04, 1.29). Conclusion The study concludes that promoting girls’ education, awareness-building programs about the adverse effects of early marriage and proper application of the child marriage restraint act, particularly in disadvantaged communities are recommended.

A rapid growth in world population is putting a pressure on agricultural products due to their worldwide demand. Contrastively, agricultural activities developed during green revolution are becoming unsustainable in current climatic change and surging population. Therefore, innovative techniques are the need of time to combat the rising world food demand. Nanotechnology, that is offering more sustainable and resilient agricultural system with improvement in food security, is an important driver to bring the agri-tech revolution. Here, we explored the opportunities of nanotechnology application to combat biological and environmental stress in plants. We present the application of various kinds of nanosensors for different environmental stresses and emphasized on the need to design and propose new nanotechnologies. This review also highlights the challenges for safely moving from labs to field studies and the strategies on how these challenges can be surmounted. Different strategies that may be helpful in bringing the agricultural sustainability includes prioritizing the agricultural research and development through full life cycle field studies on nanosensors application, interconnecting the different organizations to take actions regarding regularization of nanosensors application in agriculture, collaboration with policy makers and stakeholders for sustainable execution.

Abstract Objectives To explore relationship among perceived stress regarding loneliness, interpersonal trust and institutional trust of expatriates during the early COVID-19 period (from 30th March to 30th May 2020). Methods Data from 21,439 expatriates were extracted from COVIDiSTRESS global survey. The outcome variable was perceived stress. The explanatory variables were age, perceived loneliness, trust (interpersonal and institutional). Pairwise correlation, and structural equation modelling were used to determine relationship among outcome and explanatory variables. Results The majority of the expatriates were female (73.85%), married (60.20%), had college degree (47.76%), and employed (48.72%). Over 63% of the total expatriates reported that the COVID-19 pandemic changed their lives. The average age of the respondents was 40.4 years (± 13.7), and the average score of perceived stress, loneliness, interpersonal and institutional trust were 25.5, 7.4, 14.2 and 40.4, respectively. We found a moderate correlation of perceived stress with age, perceived loneliness, interpersonal trust and institutional trust (p

This study aims to explore the intricate behavior of soliton-like pulses within a nonlinear and lossy electrical transmission line. The transmission line is described by a mathematical model called the “beta derivative”, which is specifically designed to characterize the propagation of electrical solitons in media with both nonlinearity and dispersion properties. To achieve this goal, the (G′/G2)-expansion method is applied to a periodically loaded nonlinear beta derivative lossy transmission line with symmetric voltage-dependent capacitances. Soliton-like pulses, including periodic singular, dark, bright, and singular waves, are obtained using the (G′/G2)-expansion method based on the voltage equation. Three-dimensional and two-dimensional graphs of some of the obtained novel solutions satisfying relevant equations are provided to understand the underlying mechanisms of the soliton family. In terms of fractionality, the profiles of dark or bright waveforms maintain their complete forms, but their smoothness increases as the fractional parameters increase. On the other hand, periodic wave solutions exhibit an increase in periodicity. By adjusting the parameters of the model, the characteristics of the waves can be modified to generate desired wave profiles. Additionally, the study involves a comprehensive comparison among solutions derived from models incorporating the beta, conformable, and M−truncated derivatives. It examines how the amplitude of the solitons is influenced by the fractional parameter, utilizing graphs to visualize this impact by assigning specific fractional parameter values. These pulse-like solitons offer promising potential for integration within telecommunication systems, where they can function as information carriers, facilitating heightened data bit rates. By leveraging the findings of this study, advancements in telecommunication technology can be pursued, leading to enhanced efficiency and improved performance.

Livestreaming has gained popularity as a new e-commerce platform, communication tool, social network, and source of entertainment for millions of users. It is important to examine the nature and history of this developing area of e-commerce since it has the potential to be exploited to overcome the COVID-19 pandemic’s challenges. Therefore, this study critically explores the consumer livestreaming purchasing behavior and proposes a model, which composed of stimulus, organism, and response as the extension of stimuli-organism-organism model. The structural equation modeling approach applies for analyzing 434 survey responses from a convenience sample. The results suggest that the stimulus variable (source credibility, response capability, platform interactivity) significantly affects the organism variables (customer engagement, swift guanxi), which in turn significantly contribute to creating responses (purchase intentions, actual purchase behavior). Customer engagement and swift guanxi also have potent mediating effects in the model. We offer novel insights into new consumer behaviors in livestream commerce that can underpin future research to promote businesses and services even under challenging conditions.

Key Clinical Message This case report documents the unusual co‐occurrence of immune thrombocytopena (ITP) and chickenpox in a 15‐year‐old girl. Initial symptoms included shortness of breath, chest pain, and heavy menstrual bleeding. Laboratory results revealed significant anemia and thrombocytopenia. Treatment involved blood transfusions, prednisolone, and iron supplementation. The patient's vesicular skin rash emerged 8 weeks later, prompting the combined diagnosis of ITP and chickenpox. Antiviral treatments, blood transfusions, and supportive care were used in the course of treatment, leading to full recovery. This case emphasizes the importance of prompt diagnosis, appropriate management, and regular follow‐up for patients with both chickenpox and ITP. The coexistence of chickenpox and ITP poses a clinical challenge due to the complex interaction between the viral infection and the immune system. The exact mechanism linking these two conditions remains unclear, making it a baffling case that warrants investigation and further understanding. As low is the occurrence of hemorrhagic chickenpox, the presentation of simultaneous chicken pox with or following ITP was found to be rarer, and thus is this enigmatic case presented. Healthcare providers should remain vigilant about such co‐occurrences to prevent complications. In order to improve treatment for instances with comparable clinical presentations and advance our collective knowledge, further study is required to better understand the mechanisms relating viral infections and ITP.

Propagation of the pressure waves in a liquid with gas bubbles is an important topic in the field of fluid dynamics and mathematical physics. The Kudryashov-Sinelshchikov equation is one of the models that describe the propagation of nonlinear waves in a bubbly liquid taking into consideration the viscosity of the liquid and the heat transfer. To explain such behaviors, we mainly focus in this study to explain the dynamics of localized waves and their variety of interaction solutions to a dimensionally reduced (2 + 1)-dimensional Kudryashov-Sinelshchikov equation with the aid of the Hirota bilinear method from N-soliton solutions. Four different forms of localized waves, including solitons, lumps, breathers, and rogues, are derived from the aforesaid equation based on the long wave limit approach. In particular, the localized waves can be used to find interaction solutions, which are the single breather or single lump formed by two solitons; interaction between one line soliton and one breather, as well as one line soliton and one lump soliton among the three solitons; interaction of the two-line soliton and one periodic breather, two periodic breathers, periodic breather and one lump soliton from the four solitons. The direction of propagation, phase shifts, shape, energy, and the variety of interaction solutions of localized waves are affected by these parameters. Moreover, analytical and graphical illustrations of these interaction solutions and their propagation properties are shown by the three-dimensional and density plots with the help of Maple 17. These newly discovered solutions in this study can be used to illustrate the interaction phenomenon of localized waves on ocean surfaces.

Educating boys about puberty and menstruation has been hypothesized to aid in reducing menstrual stigma and negative attitudes about menstruation. We developed and piloted a school-based intervention for girls and boys to increase knowledge about puberty and foster a more supportive environment for menstruating schoolgirls. In this sub-study, we conducted 24 formative in-depth interviews and four group vignette exercises for schoolboys to develop the intervention package. We then carried out pre- and postintervention surveys and conducted four follow-up focus group discussions to determine the feasibility, acceptability, and effects of the intervention package among schoolboys and to develop recommendations for scale up. During the formative phase, boys reported minimal knowledge concerning puberty but felt puberty education was vital for all. Following the intervention, boys' awareness of menstruation increased compared to baseline [PD: 15%; 95% confidence interval (CI): 2, 29]. The reported comfort level of discussing puberty-related issues in a school club or with friends also increased [PD: 13%; 95% CI: 2, 24]. In focus groups, boys reported finding the sessions helpful and informative. Engagement of schoolboys, combined with well-delivered intervention materials and social and behavior change communication interventions is feasible and can contribute to a more supportive and girl-friendly environment in schools. HIGHLIGHTS Establishing a common pool of accurate information about puberty and menstruation creates room for open discussion and destigmatization of menstruation.; Engagement of schoolboys, combined with well-delivered intervention materials and social and behavior change communication interventions can contribute to more supportive and girl-friendly environments in schools. This in turn may contribute to lower school dropout rates.;

Abstract The objective of this study was to investigate the effects of health facility-level factors, including the availability of long-acting modern contraceptives (LAMC) at the nearest health facility and its distance from women’s homes, on the occurrence of unintended pregnancy that resulted in a live birth. We analysed the 2017/18 Bangladesh Demographic and Health Survey data linked with the 2017 Bangladesh Health Facility Survey. The weighted sample comprised 5051 women of reproductive age, who had at least one live birth within 3 years of the survey. The outcome variable was women’s intention to conceive at their most recent pregnancy that ended with a live birth. The major explanatory variables were the health facility level factors. A multi-level multinomial logistic regression model was used to assess the association of the outcome variable with explanatory variables adjusting for individual, household, and community-level factors. Nearly 21% of the total respondents reported that their most recent live birth was unintended at conception. Better health facility management systems and health facility infrastructure were found to be 14–30% protective of unintended pregnancy that resulted in a live birth. LAMC availability at the nearest health facility was associated with a 31% reduction (95% CI 0.50–0.92) in the likelihood of an unwanted pregnancy that resulted in a live birth. Health facility readiness to provide LAMC was also associated with a 14–16% reduction in unintended pregnancies that ended with a birth. The likelihood of unintended pregnancy that resulted in a live birth increased around 20–22% with the increased distance of the nearest health facility providing LAMC from the women’s homes.The availability of health facilities near women’s homes and access to LAMC can significantly reduce unintended pregnancy. Policies and programs to ensure access and affordability of LAMC across current health facilities and to increase the number of health facilities are recommended.

Salinity and waterlogging stresses have catastrophic effects on plants. Physiological and molecular mechanisms of plant responses to individual salinity and waterlogging stresses have been widely investigated. Several research studies have been conducted to understand the combined effects of salinity and waterlogging on plant growth, photosynthesis, and mineral homeostasis, but no systematic review has been performed yet to comprehend the cumulative effects of salinity and waterlogging on plants. This work employed a systematic approach to examine how plants respond to combined salinity and waterlogging stress compared to individual stresses, and to identify potential research gaps in this field. Our analysis indicates that combined salinity and waterlogging stress inhibits growth processes more strongly than salinity or waterlogging stress alone. In addition, the combined effect of salinity and waterlogging on photosynthesis and ionic homeostasis is greater than the sum of the individual effect of each. Our analysis further implies that tolerance to combined salinity and waterlogging stress is mostly determined by salinity tolerance. An examination of subgroups found that hydrophytes are more vulnerable to combined salinity and waterlogging than halophytes. We identified several research gaps that should be addressed in future research to enhance plant salinity and waterlogging stress tolerance.

Abstract Background Globally, many countries are adopting evidence-based workforce planning that facilitates progress towards achieving sustainable development goals for reproductive, maternal newborn and child health. We reviewed case studies on workforce planning for reproductive maternal newborn child health services at primary care level facilities using workload indicators of staffing need in five countries. Method Using available workload indicators for staffing need reports from Bangladesh, Ghana, Kenya, Sultanate of Oman and Papua New Guinea, we generated descriptive statistics to explore comparable workload components and activity standards, health service delivery models with an emphasis on the primary care levels and the specific health occupations offering interventions associated with reproductive maternal, newborn and child health services. Results The health services delivery models vary from one country to another. The results showed variability in the countries, in the workload components and activity standards of each regardless of facility level or occupational groups involved. All the countries have decentralized health services with emphasis on comprehensive primary care. Reproductive, maternal and new-born child health care services include antenatal, postnatal, immunization, family planning, baby wellness clinics, delivery and management of integrated minor childhood illnesses. Only Sultanate of Oman offers fertility services at primary care. Kenya has expanded interventions in the households and communities. Conclusion Since the health care services models, health services delivery contexts and the health care worker teams vary from one country to another, the study therefore concludes that activity standards cannot be adopted or adapted from one country to another despite having similar workload components. Evidence based workforce planning must be context-specific, and therefore requires that each country develop its own workload components and activity standards aligned to their local contexts.

Abstract The purpose of this study was to estimate the age‐standardised prevalence, awareness, treatment, and control of hypertension and to identify their risk factors in Bangladeshi adults. Data from 12 904 adults aged 18–95 years, available from the most recent nationally representative 2017–2018 Bangladesh Demographic and Health Survey were used. Hypertension was defined as having systolic blood pressure ≥140 mmHg and/or a diastolic blood pressure ≥90 mmHg, and/or taking anti‐hypertensive drugs to control blood pressure. Age‐standardized prevalence of hypertension and management were estimated with direct standardisation. A multilevel mixed‐effects Poisson regression model with a robust variance was used to identify risk factors associated with hypertension and its awareness, treatment, and control. The overall age‐standardized prevalence of hypertension was 26.2% (95% CI, 25.5‐26.9); (men: 23.5%, women: 28.9%). Among those with hypertension (n = 3531), 36.7% were aware that they had the condition, and only 31.1% received anti‐hypertensive medication. The prevalence of controlled hypertension was 12.7% among those with hypertension and 43.6% among those treated for hypertension (n = 1306). Factors independently associated with hypertension were increasing age, higher body mass index, being women, having diabetes, and residing in selected administrative divisions. A declining trend of hypertension control was observed with increasing age and low education. Hypertension is highly prevalent (one in four) in Bangladeshi adults, while awareness, treatment, and control are low. Irrespective of the risks associated with hypertension and its management, programs to increase its awareness, treatment, and control should be given high priority in reducing hypertension prevalence and improving hypertension control in Bangladesh.

Purpose – Purpose of the study is to build an integrated model of tourist destination advocacy explaining how tourists’ revisit intention is affected by its direct and mediating effects, integrated with destination experience, tourist satisfaction, and destination image. Design/methodology/approach – Data is collected online using a self-administered structured questionnaire tool, and the survey is hosted in a Google Doc. SPSS and SEM-Amos are used to analyze the data (443 samples) after successful data cleaning and outlier elimination. Findings – All of the hypotheses were shown to be true in this investigation, with the exception of two. The findings confirmed that tourists’ destination experiences improve tourists’ satisfaction, destination advocacy and destination image but not destination revisit intention. The likelihood of revisit intention is significantly influenced by destination satisfaction and image. Furthermore, destination satisfaction, destination advocacy and destination image significantly mediate the link between destination experience and revisit intention. Originality/value – This study contributes to the existing literature on consumer behavior in tourist destinations, and would guide practitioners towards effective destination management. Research limitations – Due to the lack of control factors on the relationship between all predecessors, destination revisit intentions, and all of the data gathered from domestic visitors, the current study may have limited the applicability of its findings. Therefore, additional research is necessary to validate these results across a variety of samples in order to draw generalizations.

In this paper, the lumps with their interactions (lump-single and lump-double stripes), and breather wave solutions are constructed to the new integrable (2 + 1)-dimensional Boussinesq equation via the Hirota bilinear method. The propagations of the obtained lumps, lump-stripes, and breather wave solutions of the aforesaid equation are presented through some 3D and 2D graphs. All of the graphs are given to show their correct wave profiles. The graphical outputs demonstrate that lump waves propagate in all directions throughout space. However, the amplitudes and forms of lump waves remain constant during their propagation in any direction. On the other hand, the lump wave travels along with the stripes for the lump and stripes solutions. Furthermore, two homoclinic test approaches are used to produce the breather wave solutions to the aforesaid equation. It is found that breather waves propagate in a specific direction on a constant period. In addition, the effects of constant coefficients of the model are presented also graphically. It is found that the amplitudes of all obtained wave solutions are changed with the change of constant coefficients of the model..The outcomes of the study can be useful for a better understanding of wave propagation dynamics in shallow water under gravity.

Objective: This study aimed to explore the seroprevalence of Brucella spp. in goats in some selected areas of Bangladesh. Materials and Methods: This study was conducted in different goat-populated regions of Bangladesh from July 2017 to June 2018. A total of 208 serum samples were randomly collected from goats in Jashore (n = 50), Jhenidah (n = 22), Tangail (n = 40), Savar (n = 46), Thakurgaon (n = 18), and Bandarban (n = 32) areas. The samples were subjected to determine the presence of antibodies against Brucella spp. by rose bengal plate test (RBPT) and competitive enzyme-linked immunosorbent assay (c-ELISA). Results: Overall, the seroprevalence of Brucellosis in goats was 4.33% (n = 9/208) by RBPT and 2.40% (n = 5/208) by c-ELISA. The seroprevalence of brucellosis on the basis of RBPT was 6% (buck: 0%, doe: 6%) in Jashore, 4.5% (buck: 0%, doe: 4.5%) in Jhenidah, 2.5% (buck: 0%, doe: 2.5%) in Tangail, 4.35% (buck: 0%, doe: 4.35%) in Savar, 6.25% (buck: 0%, doe: 6.25%) in Bandarban, and 5.56% (buck: 0%, doe: 5.56%) in Thakurgaon. On the other hand, the seroprevalence of brucel¬losis by c-ELISA was 4% (buck: 0%, doe: 4%) in Jashore, 4.5% (buck: 0%, doe: 4.5%) in Jhenidah, 3.13% (buck: 0%, doe: 3.13%) in Bandarban, and 5.56% (buck: 0%, doe: 5.56%) in Thakurgaon. Brucellosis was more prevalent (p > 0.001) in does aging 34 years. Conclusion: Goats from different areas of Bangladesh are caring antibodies against Brucella organisms. Further bacteriological investigations are necessary. [J Adv Vet Anim Res 2021; 8(1.000): 123-128]

Objective: In this study, we investigated the efficacy and safety of remdesivir and tocilizumab combination therapy against dexamethasone for the management of severe COVID-19 patients.Methods: This was a multicenter study. Cases were randomly chosen and divided into two groups using an odd–even ratio of 1:1 applied to the hospital registration number. Group A received remdesivir [5 mg/kg (40 kg) on day 1 and then 2.5 mg/kg (40 kg) daily] + tocilizumab [8 mg/kg up to 800 mg highest 12 h apart], and group B was the control and received dexamethasone 6 mg/day. In addition, a broad-spectrum antibiotic and other essential treatments were received by all patients. To evaluate the mortality risk, the sequential organ failure assessment (SOFA) score was calculated on day-1. Treatment outcomes were measured as time to clinical improvement; mortality rate; duration of ICU stay; total period of hospitalization; the rate of (Supplementary Material) oxygen use; time to clinical failure; National Early Warning Score-2 (NEWS), and the percentage of lung recovery on CT of chest on discharge. Clinical trial registration ID: NCT04678739.Results: Remdesivir-Tocilizumab group had a lower mortality rate (25.49%) than the control (30.77%). The time to clinical improvement (Group A-9.41; B-14.21 days), NEWS-2 on discharge (Group A-0.89; B-1.2), duration of ICU stay (Group A-7.68; B-10.58), and duration of hospitalization (Group A-9.91; B-14.68) were less in the treatment group. Group A had a better percentage of lung recovery on chest CT than the control (Group A-22.13; B-11.74). All these differences were statistically significant (p=

Abstract Background Access to washroom facilities and a place to dispose of menstrual waste are prerequisites for optimal menstrual hygiene management in schools. Like other low- and middle-income countries, Bangladeshi schools lack facilities for girls to change and dispose of their menstrual absorbents. We explored existing systems for disposing of menstrual absorbent wastes in urban and rural schools of Bangladesh and assessed the feasibility and acceptability of alternative disposal options. Methods We explored how girls dispose of their menstrual products, identified girls’ preferences and choices for a disposal system and piloted four disposal options in four different schools. We then implemented one preferred option in four additional schools. We explored girls’, teachers’, and janitors’ perspectives and evaluated the acceptability, feasibility, and potential for sustainability of the piloted disposal system. Results Barriers to optimal menstrual hygiene management included lack of functional toilets and private locations for changing menstrual products, and limited options for disposal. Girls, teachers, and janitors preferred and ranked the chute disposal system as their first choice, because it has large capacity (765 L), is relatively durable, requires less maintenance, and will take longer time to fill. During implementation of the chute disposal system in four schools, girls, teachers, and janitors reported positive changes in toilet cleanliness and menstrual products disposal resulting from the intervention. Conclusions The chute disposal system for menstrual products is a durable option that does not require frequent emptying or regular maintenance, and is accepted by schoolgirls and janitors alike, and can improve conditions for menstrual hygiene management in schools. However, regular supervision, motivation of girls to correctly dispose of their products, and a long-term maintenance and management plan for the system are necessary.

Abstract Background Worldwide people in disorder of sex development (DSD) faces multiple barriers while seeking their social rights, particularly healthcare services. We aimed to explore the healthcare opportunities available to them, using patterns of healthcare utilization and difficulties faced by DSD population in accessing healthcare services in Bangladesh. Methods Data from a total of 945 DSD population and 71 medical staff were analyzed, collected from three major divisions (Dhaka, Chittagong, and Rajshahi) in Bangladesh during the period of January to December of 2017. A structured questionnaire was used to collect data via face-to-face interviews. Descriptive statistic was used to determine the frequencies of the visit by the DSD population in healthcare facilities as well as to analyze difficulties experienced by the DSD population in getting healthcare services. Multivariate regression analysis was used to explore the association between perceived barriers in getting healthcare services and failures of the DSD population to receive the healthcare services. Results Present data revealed that around 80% of DSD population sought healthcare services from government healthcare facilities, where the overall success rate in getting healthcare services was less than 50%. The DSD population reported a number of reasons for failures in getting healthcare services, including non-friendly interaction by non-clinical hospital’s staff, non-friendly interaction by physicians, public fright as general people do not want to mingle with a DSD person, undesirable excess public interest in DSD individuals, and limitation of the treatment opportunities of hospitals to merely male or female patients. Among the stated reasons, the most frequently reported reason was non-friendly interaction by physicians (50.27%), followed by undesirable excess public interest in DSD individuals (50.16%). Conclusion DSD population in Bangladesh have limited access to healthcare facilities and facing multiple barriers to get healthcare services. Initiatives from the government and social organizations are important to ensure their access to healthcare services.

Abstract Several definitions and criteria of the first-flush are being used to assess and control the nonpoint source (diffuse) pollution. The common consensus is that the first-flush is generally noticed in the small catchments (e.g. 10 ha) without on-site monitoring being conducted. However, it is also recommended to come up with a simplistic approach of designing the best management practices (BMPs) to capture and treat certain depth of the initial storm runoff (e.g. first 20 mm), which will help reduce the effect of nonpoint source (NPS) pollution.

To estimate the age-standardized prevalence of diabetes and prediabetes and identify factors associated with these conditions at individual, household, and community levels. Data from 11952 Bangladeshi adults aged 18–95 years available from the most recent Bangladesh Demographic and Health Survey 2017–18 were used. Anthropometric measurements and fasting blood glucose samples were taken as part of the survey. Prevalence estimates of diabetes and prediabetes were age-standardized with direct standardization, and risk factors were identified using multilevel mix-effects Poisson regression models with robust variance. The overall age-standardised prevalence of diabetes was 9.2% (95%CI 8.7–9.7) (men: 8.8%, women: 9.6%), and prediabetes was 13.3% (95%CI 12.7–13.9) (men: 13.0%, women: 13.6%). Among people with diabetes, 61.5% were unaware that they had the condition. 35.2% took treatment regularly, and only 30.4% of them had controlled diabetes. Factors associated with an increased prevalence of having diabetes were increasing age, male, overweight/obesity, hypertension, being in the highest wealth quintile, and living in the Dhaka division. People currently employed and living in the Rangpur division were less likely to have diabetes than those currently not employed and living in the Barishal division. Diabetes and prediabetes affect a substantial proportion (over one-quarter) of the Bangladeshi adult population. Continuing surveillance and effective prevention and control measures, focusing on obesity reduction and hypertension management, are urgently needed.

The Sustainable Development Goals 3 targets significant reductions in maternal and under-five deaths by 2030. The prevalence of these deaths is significantly associated with short birth intervals (SBI). Identification of factors associated with SBI is pivotal for intervening with appropriate programmes to reduce occurrence of SBI and associated adverse consequences. This study aimed to determine the factors associated with SBI in Bangladesh. A total of 5,941 women included in the 2017/18 Bangladesh Demographic and Health Survey 2017/18 and 1,524 healthcare facilities included in the 2017 Bangladesh Health Facility were linked and analysed. The sample was selected based on the availability of the birth interval data between the two most recent subsequent live birth. SBI was defined as an interval between consecutive births of 33 months or less, as recommended by the World Health Organization and was the outcome variable. Several individual-, households-, and community-level factors were considered as exposure variables. We used descriptive statistics to summarise respondents’ characteristics and multilevel Poisson regression to assess the association between the outcome variable with exposure variables. Around 26% of live births occurred in short intervals, with a further higher prevalence among younger, uneducated, or rural women. The likelihoods of SBI were lower among women aged 20–34 years (PR, 0.14; 95% CI, 0.11–0.17) and ≥35 years (PR, 0.03; 95% CI, 0.02–0.05) as compared to the women aged 19 years or less. Women from households with the richest wealth quintile experienced lower odds of SBI (PR, 0.61; 95% CI, 0.45–0.85) compared to those from the poorest wealth quintile. The prevalences of SBI were higher among women whose second most recent child died (PR, 5.23; 95% CI, 4.18–6.55), those who were living in Chattogram (PR, 1.52; 95% CI, 1.12–2.07) or Sylhet (PR, 2.83, 95% CI, 2.08–3.86) divisions. Availability of modern contraceptives at the nearest healthcare facilities was 66% protective to the occurrence of SBI (PR, 0.34; 95% CI, 0.22–0.78). Also, the prevalence of SBI increased around 85% (PR, 1.85; 95% CI, 1.33–2.18) for every kilometer increase in the distance of nearby health facilities from women’s homes. Targeted and tailored regional policies and programmes are needed to increase the awareness of SBI and associated adverse health outcomes and availability of modern contraception in the healthcare facilities.

In this work, four different metakaolin samples (C01, A6060, B6075, and C12090) were investigated to determine their constituent elements and the relative quantities of the oxide contents associated with each of the elements. Kaolin samples were collected from different sites at Okpella, a village in the Edo state of Nigeria, West Africa. The metakaolin was produced by calcination at 750℃, which was followed by the dealumination process. The prepared samples were characterized by Field Emission Scanning Electron Microscope (FE-SEM), Energy Dispersive X-ray Spectroscopy (EDS), Fourier Transform Infrared Resonance (FTIR) spectroscopy, and X-ray diffraction (XRD) technique. Digital images were obtained and analyzed to determine the texture and porosity of the samples. FE-SEM images showed a slight difference in the morphology of the samples. Differing percentages of metal oxides were determined from the samples using EDS analysis. The major oxides present in all the samples were Silica (Silicon oxide) and Alumina (Aluminium dioxide). Aluminium was completely absent in C12090 but had a large percentage of silicon (36%).

In this paper, the distribution of thermodynamic variables in the protoplanets formed by gravitational instability in the mass range 0.3−10MJ (1MJ=1 Jupiter mass = 1.8986×1030 gm) is investigated in their initial state by solving the structure equations via the Adomian decomposition method. Concerning the heat transfer in the protoplanets, the mode of convection is taken into account. The outcomes indicate that there is a reasonably good agreement between the Adomian semi-analytical solution containing only first 8 terms and the numerical results.

As an edible oil, palm oil is also safe and reliable in dyeing, and the residual palm oil after dyeing can be recycled and used continuously, which is green and environmentally friendly and has great research prospects. In this research, raw ramie yarn, used for traditional grass cloth, was dyed in a palm oil medium using Reactive Blue 194. Studying the adsorption and diffusion behaviour in the dyeing process is necessary. Additionally, the kinetics and isotherm model of dyeing raw ramie yarn with Reactive Blue 194 in palm oil is studied, and the adsorption behaviour between them is discussed. For a better understanding, the raw ramie yarn dyeing adsorption behaviour was also carried out in a water medium. It was found that the dyeing rates in palm oil are distinctly faster than in water. Kinetics data suggested that the pseudo-second-order model fitted for both dyeing mediums (palm oil and water) of the adsorption of the Reactive Blue 194 dye onto raw ramie yarn. Afterward, the adsorption isotherms’ results denote that the Langmuir model was suitable for palm oil dyeing medium while the Freundlich model was suited for water medium. Overall, this study has demonstrated that raw ramie yarn dyeing in a palm oil medium could be a sustainable colouration route for textile fibres with a greater dye exhaustion percentage.

In this study, we focus on extracting soliton solutions to the differential equation of fractional order governing wave propagation in low-pass electrical transmission lines by the (G'/G2)-expansion method. By a simple linear fractional transformation, we convert the model equation to an ordinary differential equation. Thereupon, through the use of the (G'/G2)-expansion method, various types of solitary wave solutions to the equation of interest are achieved. All the received solutions are verified using Maple software. To show the dynamical behavior of some of the acquired solutions representing singular-periodic, singular, anti-kink, periodic, and bright soliton solutions, their two and three-dimensional profiles are displayed by selecting suitable values of the solutions’ free parameters. Impacts of the fractionality and free parameters on the dynamical behavior of the attained soliton solutions are presented graphically and discussed elaborately. A comparison of our explored solutions with those obtained in the literature is also made. The comparison, wherever available, shows no noticeable difference between our attained results and the published ones. The results that came out through this investigation expose the productivity and powerfulness of the adoptive method for excerpting a diversity of wave solutions to nonlinear evolution equations arising in the fields of mathematics, engineering, and physics.

In the light of computational chemistry, based on morpholinium cation-based Ionic Liquid, their different types of physical, chemical, and biological properties is highlighted. The physical properties are evaluated through the Density Functional Theory (DFT) of Molecular Mechanics and also examine the chemical and biological properties. The difference between Highest Occupied Molecular Orbital (HOMO) and Lowest Unoccupied Molecular Orbital (LUMO) is starting from 11.19 to 4.00, which means that their chemical reactions change as soon as an anion change is done. Biological activity of predictions given by QSAR calculation is forecasted. Where the value of all the LogP that is available is positive, which indicates hydrophobic, on the other hand, PIC50 calculations are found that all the values below 5 are biologically active. To identify these molecules, computational data is used to determine the vibrational spectrum and electronic spectrum.

Abstract Background Anxiety is a common psychiatric disorder among adolescents in developing countries. This study aimed to examine the risk factors of anxiety disorder and the adverse consequences of anxiety disorder among adolescents in Bangladesh. Methods A total of 2,989 adolescent data of the 2014 Global School‐based Student Health Survey (GSHS), Bangladesh, was analyzed WHO. The prevalence of anxiety disorder across psychosocial and socio‐environmental factors was calculated as descriptive statistics, whereas their effects on occurring anxiety disorder were determined using the unadjusted and adjusted multivariable binary logistic regression model. The consequences of anxiety disorder were also determined using the multivariable binary logistic regression model. Results The prevalence of anxiety disorder was 4.7%, which was found higher among female than their male counterparts. The psychosocial factors were found associated with the anxiety disorder are loneliness (AOR: 2.26, 95% CI: 1.08–4.72), being bullied (AOR: 6.00, 95% CI: 3.14–11.47), and physical abuse (AOR: 2.12, 95% CI: 1.07–4.21). Moreover, poor understandings with parents (AOR: 1.75, 95% CI: 1.02–3.01) and lack of peer support (AOR: 2.23, 95% CI: 1.18–4.23) were the socio‐environmental factors that found associated with the anxiety disorder. Subgroup analysis across gender found these associations were consistent for adolescent male and female. Moreover, the likelihood increased with the increasing number of the adverse psychosocial, or socio‐environmental factors. Conclusions Around 5% of school‐going adolescents in Bangladesh reported anxiety associated with the exposure of single or multiple adverse psychosocial and socio‐environmental factors including bullying and physical abuse. Early screening and interventions are essential, targeted to adolescent at risk, which could reduce the rate of anxiety disorder among adolescent in Bangladesh.

5-fluorouracil (5-FU) has been shown to have suffered from resistance which demands a solution entailing the development of 5-FU analogues. Our study aims to design a number of analogues of 5-FU and evaluate their effectiveness against thymidylate synthase (TS) in silico compared to parent 5-FU with an effort to obtain better hit(s). All the molecules were optimized by molecular mechanics method utilizing MM2 forcefield parameters. Molecular docking of these molecules against TS was performed to catch on the binding strength of these molecules, determination of binding energy & interaction types of each ligand-target complex as well as subsequent analysis. PRA10 showed highest binding affinity (-9.1 Kcal/mol). Although binding energy of PRA6 & PRA14 are slightly lower than PRA10, they can be of special interest since they interact with crucial amino acids for binding and exhibit substantial non-bonded interactions. Residue analysis revealed that Arg50A, Arg175B, Arg215A, Ser216A, Arg176B and Asn226A of TS active site were crucial for binding/interaction. The best scored drug candidates demonstrated considerable pharmacokinetic as well as druglike properties. The present study also revealed that PRA6, PRA10 and PRA14 can be potential anticancer drugs for further development.

Mesenchymal stem cells therapy opened new perspective in the management of osteoarthritis. This study focuses on a randomized controlled trial pilot on 10 patients of osteoarthritis knees to evaluate the intra-articular injections of mesenchymal stem cells could improve the symptoms, functional limitation and regeneration of cartilage. Mesenchymal stem cells were obtained from peripheral blood after mobilization of blood cell with granulocyte colony stimulating factor by apheresis machine. Single dose of mesenchymal stem cells were injected into the affected joints, WOMAC questionnaires scale used to record pre and post-treatment improvement, cartilage thickness measured by high frequency ultrasonogram. Four patients were having Grade II and six were having Grade III osteoarthritis. Kellgren-Lawrence scale was used for radiological grading. Pain score were decreased at the end of 24th weeks from 14.8 ± 2.2 to 4.1 ± 1.3, Stiffness score decreased from 5.8 ± 0.6 to 0.7 ± 0.6, Physical function limitation score reduced from 46.7 ± 6.5 to 20.3 ± 2.5. There was minor improvement of range of motion and cartilage thickness changes. This study demonstrates that mesenchymal stem cells injections improves all parameters of knee osteoarthritis and minimal regeneration of damaged cartilage.

A 60-year-old diabetic male patient presented with persistent left shoulder joint pain for the last 6 months following coronary artery bypass graft (CABG) surgery. The pain was insidious onset, non-radiating, and dull which aggravated by movement as well as on left lateral position during sleep. However, the pain was not associated with morning stiffness. He had been treated with oral anti-diabetic medications for diabetes mellitus for the last 15 years. However, recently he required to switch to premixed insulin injection for good control of his glycemic status. Apart from post CABG status and diabetes mellitus, he was relatively well and had no other significant medical records like direct trauma over the shoulder joint.

This study examined inequalities in the utilization of maternal reproductive health care services in urban Bangladesh. Data of 6,617 urban women were extracted from most recent two rounds of Bangladesh Demographic and Health Survey, conducted in the years 2011 and 2014. Inequalities in the utilization of antenatal checkup, receiving care from a skilled birth attendant, delivery in health care facilities, and postnatal care were investigated through concentration index. Contributions of selected predictors to inequalities were estimated by using the regression-based decomposition method. Noticeable inequalities were observed. Concentration index for utilization of at least one antenatal care visit was 0.09, four or more antenatal visits was 0.17, care from skilled birth attendant was 0.16, delivery care in health care facilities was 0.17, and postnatal care within 2 days of delivery was 0.19. Exposure to mass media, educational status of women and their spouses, wealth status, employment, birth order, and age of pregnancy were significant determinants of inequalities. There was a gradient in the utilization of services when examined across wealth status. Those with unfavorable social determinants of health reported low levels of utilization. Alongside providing tailored health care services to urban poor women, efforts should be made to reduce inequalities in social determinants of health.

Abstract Background Despite growing evidence in support of exclusive breastfeeding (EBF) among infants in the first 6 months of birth, the debate over the optimal duration of EBF continues. This study examines the effect of termination of EBF during the first 2, 4 and 6 months of birth on a set of adverse health and nutritional outcomes of infants. Methods Three waves of Bangladesh Demographic and Health Survey data were analysed using multivariate regression. The adverse health outcomes were: an episode of diarrhea, fever or acute respiratory infection (ARI) during the 2 weeks prior to the survey. Nutritional outcomes were assessed by stunting (height-for-age), wasting (weight-for-height) and underweight (weight-for-age). Population attributable fraction was calculated to estimate percentages of these six outcomes that could have been prevented by supplying EBF. Results Fifty-six percent of infants were exclusively breastfed during the first 6 months. Lack of EBF increased the odds of diarrhea, fever and ARI. Among the babies aged 6 months or less 27.37% of diarrhea, 13.24% of fever and 8.94% of ARI could have been prevented if EBF was not discontinued. If EBF was terminated during 0–2 months, 2–4 months the odds of becoming underweight were 2.16 and 2.01 times higher, respectively, than babies for whom EBF was not terminated. Conclusion Children who are not offered EBF up to 6 months of their birth may suffer from a range of infectious diseases and under-nutrition. Health promotion and other public health interventions should be enhanced to encourage EBF at least up to six-month of birth. Trail registration Data of this study were collected following the guidelines of ICF International and Bangladesh Medical Research Council. The registration number of data collection is 132,989.0.000 and the data-request was registered on September 11, 2016.

Objective To compare the prevalence of unintended pregnancy measured by the Demographic and Health Survey (DHS) and the London Measure of Unplanned Pregnancy in Bangladesh, and explore the extent of discordance between the measures and the factors associated with the discordance. Methods In 2023, we conducted a cross-sectional survey in four randomly selected districts in Bangladesh: Kurigram, Mymensingh, Pabna and Satkhira. We randomly selected 20 hospitals, five from each district. We collected data from 1200 women who had recently delivered a baby and were visiting the hospitals for postnatal care. We interviewed the women about their pregnancy intention in their last pregnancy using questions in the DHS and the London Measure of Unplanned Pregnancy and examined the discordance in their responses. We used multivariable logistic regression analysis to identify factors associated with discordant responses in reported pregnancy intention. Findings The prevalence of unintended pregnancy was 24.3% (292/1200) using the DHS measure and 31.0% (373/1200) using the London Measure of Unplanned Pregnancy. Discordance in responses to pregnancy intention between the two measures was 27.1% (325/1200). Factors associated with discordance were older age, female sex of the last child born, having more than two children, being in a poorer wealth quintile, living in a rural area and living in Kurigram district. Conclusion The prevalence of unintended pregnancy in Bangladesh measured by the DHS measure may be an underestimate, suggesting that the adverse effects of unintended pregnancy are greater than realized and emphasizing the need to bolster Bangladesh's family planning programme. Objectif Comparer la prevalence des grossesses non desirees mesuree par l'Enquete demographique et de sante (EDS) et par la London Measure of Unplanned Pregnancy au Bangladesh et explorer letendue de la discordance entre les mesures et les facteurs associes a cette discordance. Methodes En 2023, nous avons mene une enquete transversale dans quatre districts du Bangladesh choisis au hasard: Kurigram, Mymensingh, Pabna et Satkhira. Nous avons choisi au hasard 20 hopitaux, cinq par district. Nous avons recueilli des donnees aupres de 1200 femmes qui avaient recemment accouche et qui se rendaient a l'hopital pour des soins postnatals. Nous avons interroge ces femmes sur le desir de leur derniere grossesse en leur posant des questions issues de l'Enquete demographique et de sante et de la London Measure of Unplanned Pregnancy. Nous avons ensuite examine la discordance entre leurs reponses. Nous avons applique une analyse de regression logistique multivariable afin d'identifier les facteurs associes aux reponses discordantes dans les intentions de grossesse declarees. Resultats La prevalence des grossesses non desirees etait de 24,3% (292/1200) selon l'Enquete demographique et de sante et de 31,0% (373/1200) selon la London Measure of Unplanned Pregnancy. La discordance dans les reponses portant sur l'intention de grossesse entre les deux mesures etait de 27,1% (325/1200). Les facteurs associes a la discordance etaient l'age avance, le sexe feminin du dernier enfant ne, le fait d'avoir plus de deux enfants, d'appartenir a un quintile de richesse inferieur, de vivre dans une zone rurale et de vivre dans le district de Kurigram. Conclusion Il se peut que la prevalence des grossesses non desirees au Bangladesh, telle que mesuree par l'Enquete demographique et de sante, soit sous-estimee, ce qui suggere que les effets defavorables des grossesses non desirees sont plus importants qu'on ne le pense et souligne la necessite de renforcer le programme de planification familiale du Bangladesh. Objetivo Comparar la prevalencia del embarazo no deseado medida por la Encuesta Demografica y de Salud (EDS) y la London Measure of Unplanned Pregnancy en Bangladesh, y explorar el grado de discordancia entre las medidas y los factores asociados con la discordancia. Metodos En 2023, se realizo una encuesta transversal en cuatro distritos de Bangladesh seleccionados al azar: Kurigram, Mymensingh, Pabna y Satkhira. Se seleccionaron al azar 20 hospitales, cinco de cada distrito. Se recopilaron datos de 1200 mujeres que habian dado a luz recientemente y acudian a los hospitales para recibir atencion posnatal. Se entrevisto a las mujeres sobre su intencion de embarazo en su ultimo embarazo utilizando preguntas de la EDS y la London Measure of Unplanned Pregnancy, y se examino la discordancia en sus respuestas. Se utilizo un analisis de regresion logistica multivariable para identificar los factores asociados a las respuestas discordantes en la intencion de embarazo declarada. Resultados La prevalencia de embarazos no deseados fue del 24,3% (292/1200) utilizando la medida EDS y del 31,0% (373/1200) utilizando la London Measure of Unplanned Pregnancy. La discordancia en las respuestas a la intencion de embarazo entre las dos medidas fue del 27,1% (325/1200). Los factores asociados a la discordancia fueron la edad avanzada, el sexo femenino del ultimo hijo nacido, tener mas de dos hijos, pertenecer a un quintil de riqueza mas pobre, vivir en un area rural y vivir en el distrito de Kurigram. Conclusion La prevalencia de embarazos no deseados en Bangladesh medida por la EDS puede ser una subestimacion, lo que sugiere que los efectos adversos de los embarazos no deseados son mayores de lo que se cree y subraya la necesidad de reforzar el programa de planificacion familiar de Bangladesh., Introduction Globally, about half of pregnancies (roughly 121 million) are unintended, with low- and middle-income countries bearing the brunt due to lower use of modern contraception and higher unmet contraceptive [...]

Background: Reproductive health (RH) is a critical component of women’s health and overall well-being around the world, especially in developing countries. We examine the factors that determine knowledge of RH care among female university students in Bangladesh. Methods: Data on 300 female students were collected from Rajshahi University, Bangladesh through a structured questionnaire using purposive sampling technique. The data were used for univariate analysis, to carry out the description of the variables; bivariate analysis was used to examine the associations between the variables; and finally, multivariate analysis (binary logistic regression model) was used to examine and fit the model and interpret the parameter estimates, especially in terms of odds ratios. Results: The results revealed that more than one-third (34.3%) respondents do not have sufficient knowledge of RH care. The X2 -test identified the significant (p < 0.05) associations between respondents’ knowledge of RH care with respondents’ age, education, family type, watching television; and knowledge about pregnancy, family planning, and contraceptive use. Finally, the binary logistic regression model identified respondents’ age, education, family type; and knowledge about family planning, and contraceptive use as the significant (p < 0.05) predictors of RH care. Conclusions and Global Health Implications: Knowledge of RH care among female university students was found unsatisfactory. Government and concerned organizations should promote and strengthen various health education programs to focus on RH care especially for the female university students in Bangladesh.
