Introduction: Diarrhoea is one of the leading causes of under-5 childhood mortality and accounts for 8% of 5.4 million global under-5 deaths. In severely malnourished children, diarrhoea progresses to shock, where the risk of mortality is even higher. At icddr,b Dhaka Hospital, the fatality rate is as high as 69% in children with severe malnutrition and fluid refractory septic shock. To date, no study has evaluated systematically the effects of inotrope or vasopressor or blood transfusion in children with dehydrating diarrhoea (eg, in cholera) and severe acute malnutrition (SAM) or severe underweight who are in shock and unresponsive to WHO-recommended fluid therapy. To reduce the mortality of severely malnourished children presenting with diarrhoea and fluid refractory shock, we aim to compare the efficacy of blood transfusion, dopamine and epinephrine in fluid refractory shock in children who do not respond to WHO-recommended fluid resuscitation., Methods and Analysis: In this randomised, three-arm, controlled, non-masked clinical trial in children 1-59 months old with SAM or severe underweight and fluid refractory shock, we will compare the efficacy of dopamine or epinephrine administration versus blood transfusion in children who failed to respond to WHO-recommended fluid resuscitation. The primary outcome variable is the case fatality rate. The effect of the intervention will be assessed by performing an intention-to-treat analysis. Recruitment and data collection began in July 2021 and are now ongoing. Results are expected by May 2023., Ethics and Dissemination: This study has been approved by the icddr,b Institutional Review Board. We adhere to the 'Declaration of Helsinki' (2000), guidelines for Good Clinical Practice. Before enrolment, we collect signed informed consent from the parents or caregivers of the children. We will publish the results in a peer-reviewed journal and will arrange a dissemination seminar., Trial Registration Number: NCT04750070., Competing Interests: Competing interests: None declared., (© Author(s) (or their employer(s)) 2023.

Objective: This study aimed to identify the associated factors of low and medium household (HH) dietary diversity (DD) compared with high DD among marginalised households in rural Bangladesh., Methods: Through the Suchana baseline survey, data on 5440 households from Sylhet and Moulvibazar districts of Bangladesh was collected between November 2016 and February 2017. Household DD was categorised as low, medium or high based on number of food groups consumed during the last 24 hours. Primary outcome measure was household DD; multinomial logistic regression was to determine independent correlations between outcome and independent variables., Results: Of the households examined, 0.72%, 31.8% and 67.5% had low, medium and high DD, respectively. Around 99% and 97% of households consumed cereals and vegetables. Cereals, fruits and legumes accounted for 36%, 18% and 16% of total food expenditure; vegetables only represented 8% of total expenditure; 70% of total monthly expenditure was on food items. Compared with high DD, low DD was significantly associated with severe food insecurity, not receiving remittance, not being supported by social safety-net programs, household size of 6-10, household income and expenditure on food below-median. Severe food insecurity was the strongest predictor of low DD. Age, occupation and educational status of the household head, amount of land owned and presence of a homestead garden, fish production and domestic violence were not significantly associated with DD., Conclusion: Our findings suggest that nine out of ten households were food insecure, and nearly two-thirds of households had high DD. Severe food insecurity was significantly associated with low DD. Expenditure on food items amounted to nearly two-thirds of total household expenditure. Diversification of income-generating activities would provide more sources of income to the households, allowing the households to spend more on non-cereal food items and increase the household dietary diversity., Competing Interests: Competing interests: None declared., (© Author(s) (or their employer(s)) 2022.

Objectives: Women's decision-making power is a dimension of empowerment and is crucial for better physical and psychosocial outcomes of mothers. Suchana , a large-scale development programme in Bangladesh, actively provided social interventions on behaviour change communication to empower women belonging to the poorest social segment. This paper aims to assess the impact of the Suchana intervention on various indicators related to women's decision-making power., Design, Setting and Participants: The evaluation design was a cluster randomised pre-post design with two cross-sectional surveys conducted among beneficiary women with at least one child aged <23 months from randomly selected poor or very poor beneficiary households in Sylhet division., Outcome Measure: Decision-making indicators included food purchases, major household purchases, food preparation, children's healthcare as well as women's own healthcare and visiting family and relatives., Results: Our findings suggest that 45% of women were able to make decisions on food purchases, 25% on major household purchases, 78% on food preparation, 59% on children's healthcare, 51% on their own healthcare and 43% on visiting family and relatives at baseline in the intervention group, whereas the results were almost the same in the control group. In contrast, at the endline survey, the respective proportions were 75%, 56%, 87%, 80%, 77% and 67% in the intervention group, which were significantly improved when compared with the control group. The prevalence of those outcome indicators were 64%, 41%, 80%, 71%, 68% and 56%, respectively, in the control group. As per multiple logistic regression analysis and structural equation modelling, the Suchana intervention had a substantial influence on the latent variable of women's decision-making power., Conclusion: In terms of food purchases, major household purchases, children's healthcare, their own healthcare and visiting family and relatives, the Suchana intervention favourably influenced the decision-making power of rural women living in a vulnerable region of Bangladesh., Trial Registration Number: RIDIE-STUDY-ID-5d5678361809b., Competing Interests: Competing interests: None declared., (© Author(s) (or their employer(s)) 2022.

Introduction: Despite economic development and augmented literacy rates, Bangladeshi households are still discriminating against girls when it comes to seeking medical care. We examined gender disparities in diarrhoeal disease severity and the treatment outcomes of under-5 children., Setting: A tertiary level diarrhoeal disease hospital in Dhaka, Bangladesh., Participants: 13 361 under-5 children admitted to the hospital between January 2008 and December 2017., Outcome Variables and Methods: The primary outcome of interest was severity of diarrhoea, defined as 'dehydrating diarrhoea' or 'non-dehydrating diarrhoea'. Multivariable logistic regression analyses were performed to assess the association between 'gender' and admission to hospital for dehydrating diarrhoea., Results: Data on 13 321 children under 5 years of age were analysed, of whom 61.5% were male and 38.5% were female. The mean (±SD) age of children with diarrhoea was 5.63 (±3.49) months. The median distance travelled to come to the hospital for admission was 10 miles (IQR: 6-25) and was significantly higher for boys (10 miles, IQR: 6-25) than girls (9.5 miles, IQR: 6-23) (p<0.001). Girls had 1.11 times higher odds (adjusted OR: 1.11, 95% CI 1.03 to 1.20, p=0.007) of presenting with dehydrating diarrhoea than boys at the time of hospital admission. Almost 20% of children received two or more medications during the period of hospital admission and this did not differ by gender. The median duration of hospital stay was 11 hours and was similar in both sexes. No gender-based disparity was observed in the management of diarrhoea and in the hospital outcome of children., Conclusion: We found that girls were more likely to have dehydrating diarrhoea when they were presented to the Dhaka hospital of International Centre for Diarrhoeal Disease Research, Bangladesh. No gender-based disparity was observed in the hospital outcome of children., Competing Interests: Competing interests: None declared., (© Author(s) (or their employer(s)) 2020.
