RESUMEN
BACKGROUND: Lead, a potent neurotoxin, causes irreversible damage to the nervous system, and low- and middle-income countries face huge health and economic productivity losses due to childhood lead exposure. In Bangladesh, informal Used Lead Acid Battery (ULAB) recycling sites are an important source of lead pollution. Little is known about lead awareness among communities exposed to ULAB recycling. Therefore, this study aims to assess knowledge, attitudes, and practices related to lead pollution among caregivers of young children and adolescents living adjacent to informal ULAB sites. METHODS: A cross-sectional study was conducted among 732 mothers of young children and adolescents in 4 districts of Bangladesh (survey and observation). Simple and multiple linear regression was conducted to describe patterns and predictors of lead-related knowledge and practices. RESULTS: 60% of respondents had heard the name 'lead' ("shisha"). The mean knowledge score was low (19 out of 44). Residents of high-risk districts, male respondents, and those with more than 5 years of schooling were significantly more likely to have higher knowledge scores than others. In terms of attitude, 52% of respondents perceived lead to be risky for human health but 43% thought lead pollution was controllable. Observation of households for lead exposure revealed that 63% of children and adolescents play or pass by ULAB sites, 29% ate non-food items, 41% of households had visible paint chips on the walls, 59% households used polished turmeric and 15% used lead-soldered cans to store foods. Among protective practices, 70% reported cleaning floors, 84% consumed iron-rich foods, and 48% consumed calcium-rich foods. CONCLUSIONS: The population had a high potential for lead exposure. Their knowledge about lead was limited, and risk perception was moderate. To reduce lead exposure and increase knowledge and awareness among the at-risk population, it is crucial to take measures such as mass awareness campaigns through media and schools. It is important to strengthen the implementation of existing policies, such as policies on leaded gasoline, paints, and lead-acid batteries, that can address the sources of lead exposure for the community.

BACKGROUND: Although under-five mortality has declined appreciably in Bangladesh over the last few decades, neonatal mortality still remains high. The objective of the study is to assess the level and determinants of preterm birth and the contribution of preterm birth to neonatal mortality. METHODS: Data for this study came from selected slums in and around Dhaka city, where; since 2015, icddr,b has been maintaining the Health and Demographic Surveillance System (HDSS). The HDSS data were collected by female Field Workers by visiting each household every three months; however, during the visit, data on the Last Menstrual Period (LMP) were also collected by asking each eligible woman to ascertain the date of conception. Gestational age was estimated in complete weeks by subtracting LMP from the date of the pregnancy outcome. In this study, 6,989 livebirths were recorded by HDSS during 2016-2018, and these births were followed for neonatal survival; both bivariate and multivariate analyses were performed. RESULTS: Out of total births, 21.7% were born preterm (before 37 weeks of gestation), and sub-categories were: 2.19% for very preterm (28 to 31 weeks), 3.81% for moderate preterm (32 to 33 weeks), and 15.71% for late preterm (34 to 36 weeks). The study revealed that preterm babies contributed to 39.6% of neonatal deaths; however, the probability of death was very high on the 1st day of birth (0.124 for very preterm, 0.048 for moderate preterm, 0.024 for late preterm, and 0.013 for term birth), and continued until the 3rd day. In the regression analysis, compared to the term neonates, the odds of neonatal mortality were 8.66 (CI: 5.63, 13.32, p<0.01), 4.13 (CI: 2.69, 6.34, p<0.01) and 1.48 (CI: 1.05, 2.08, p<0.05) respectively for very, moderate, and late preterm birth categories. The population attributable fraction for neonatal mortality was 23%, and sub-categories were 14% for very preterm, 10% for moderate preterm, and 6% for late preterm. CONCLUSIONS: Although urban slums are in proximity to many health facilities, a substantial proportion of preterm births contribute to neonatal deaths. So, pregnant women should be targeted, to ensure timely care during pregnancy, delivery, and post-partum periods to improve the survival of new-borns in general and preterm birth in particular.

BACKGROUND: Globally, major emphasis has been placed on understanding the physiological consequences of losing a pregnancy. However, its mental health impact on socially disadvantaged women remains unexplored. To further inform the field the present study investigated the prevalence and factors associated with the development of depressive symptoms and anxiety among women with a history of spontaneous abortion living in the urban slums of Dhaka, Bangladesh. METHODS: Information was obtained from 240 women who experienced a spontaneous abortion from July 2020 to December 2021. It was obtained through the urban health and demographic surveillance system (UHDSS) survey. Generalized Anxiety Disorder (GAD-7) and Patient Health Questionnaire (PHQ-9) were used to measure mental health symptoms. Bivariate and multivariate linear regression analyses were performed to assess the associated factors with the mental health outcomes. RESULTS: Of the 240 women, majority (77.50%) of the women experienced mild to severe depressive symptoms and more than half (58.75%) of the respondants experienced mild to severe anxiety, within one and half years of experiencing spontaneous abortion. A higher level of education and being employed were protective factors for anxiety and depressive symptoms, respectively. However, women with higher sexual and reproductive health rights (SRHR) knowledge had significantly increased anxiety and depressive symptoms. In contrast, receiving post-abortion care (PAC) was associated with decreased anxiety and depressive symptoms. CONCLUSION: The findings indicate that ensuring access to affordable PAC services and integrating mental health services into the standard PAC service package is crucial. This study also emphasizes the importance of providing education for women living in urban slums and encouraging them to participate in economic activities.

Background: Autism Spectrum Disorder (ASD) is a pervasive developmental disorder, which affects various multiple areas of a child's development. The objective of this study was to systematically review the available literature and appraise the effect of floortime in engaging autism disorder among children. Materials and Methods: A systematic review was performed using PubMed, PsycINFO, Science Direct, Scopus, Google Scholar, and Medline. The search terms used were DIR/floor time, ASD, floortime and autism, relationship therapy and autism, floortime, and ASDs. The studies, which described floortime in engaging children with ASD, full-text available in English, the sample had no comorbid psychiatric diagnosis, and the articles published in English from 2010 to 2020 were included in the review. Twelve studies meeting the inclusion criteria were included in the review. Results: The results showed substantial progress in different levels of functioning of autistic children with floortime. Home-based floortime improved emotive functioning, communication, and daily living skills, the parent-child interactions were improved as expressed by mothers, and also certain demographic factors of the parents have significantly influenced the floortime outcome. There were no adverse events to children or parents during floortime. Conclusions: In general, we concluded that floortime is a cost-effective, completely child-led approach, which could be initiated as early as possible. If started early by healthcare professionals, it can be vital in improving social and emotional development among children.
RESUMEN
BACKGROUND: Common psychosocial health problems (PHPs) have become more prevalent among adolescents globally during the COVID-19 pandemic. However, the psychosocial health of school-going adolescents has remained unexplored in Bangladesh due to limited research during the pandemic. The present study aimed to estimate the prevalence of PHPs (i.e., depression and anxiety) and assess associated lifestyle and behavioral factors among school-going adolescents in Bangladesh during the COVID-19 pandemic. METHODS: A nationwide cross-sectional survey was conducted among 3,571 school-going adolescents (male: 57.4%, mean age: 14.9±1.8 years; age range: 10-19 years) covering all divisions, including 63 districts in Bangladesh. A semi-structured e-questionnaire, including informed consent and questions related to socio-demographics, lifestyle, academics, pandemic and PHPs, was used to collect data between May and July 2021. RESULTS: The prevalence of moderate to severe depression and anxiety were 37.3% and 21.7%, respectively, ranging from 24.7% in the Sylhet Division to 47.5% in the Rajshahi Division for depression, and from 13.4% in the Sylhet Division to 30.3% in the Rajshahi Division for anxiety. Depression and anxiety were associated with older age, reports of poor teacher cooperation in online classes, worries due to academic delays, parental comparison of academic performance with other classmates, difficulties coping with quarantine situations, changes in eating habits, weight gain, physical inactivity and having experienced cyberbullying. Moreover, being female was associated with higher odds of depression. CONCLUSIONS: Adolescent psychosocial problems represent a public health problem. The findings suggest a need for generating improved empirically supported school-based psychosocial support programs involving parents and teachers to ensure the well-being of adolescents in Bangladesh. School-based prevention of psychosocial problems that promote environmental and policy changes related to lifestyle practices and active living should be developed, tested, and implemented.

INTRODUCTION: Children's early development is affected by caregiving experiences, with lifelong health and well-being implications. Governments and civil societies need population-based measures to monitor children's early development and ensure that children receive the care needed to thrive. To this end, the WHO developed the Global Scales for Early Development (GSED) to measure children's early development up to 3 years of age. The GSED includes three measures for population and programmatic level measurement: (1) short form (SF) (caregiver report), (2) long form (LF) (direct administration) and (3) psychosocial form (PF) (caregiver report). The primary aim of this protocol is to validate the GSED SF and LF. Secondary aims are to create preliminary reference scores for the GSED SF and LF, validate an adaptive testing algorithm and assess the feasibility and preliminary validity of the GSED PF. METHODS AND ANALYSIS: We will conduct the validation in seven countries (Bangladesh, Brazil, Côte d'Ivoire, Pakistan, The Netherlands, People's Republic of China, United Republic of Tanzania), varying in geography, language, culture and income through a 1-year prospective design, combining cross-sectional and longitudinal methods with 1248 children per site, stratified by age and sex. The GSED generates an innovative common metric (Developmental Score: D-score) using the Rasch model and a Development for Age Z-score (DAZ). We will evaluate six psychometric properties of the GSED SF and LF: concurrent validity, predictive validity at 6 months, convergent and discriminant validity, and test-retest and inter-rater reliability. We will evaluate measurement invariance by comparing differential item functioning and differential test functioning across sites. ETHICS AND DISSEMINATION: This study has received ethical approval from the WHO (protocol GSED validation 004583 20.04.2020) and approval in each site. Study results will be disseminated through webinars and publications from WHO, international organisations, academic journals and conference proceedings. REGISTRATION DETAILS: Open Science Framework https://osf.io/ on 19 November 2021 (DOI 10.17605/OSF.IO/KX5T7; identifier: osf-registrations-kx5t7-v1).

INTRODUCTION: Women experience high rates of depression, particularly during pregnancy and the postpartum periods. Using population-based data from Bangladesh and Pakistan, we estimated the burden of antenatal depression, its risk factors, and its effect on preterm birth. METHODS: The study uses the following data: maternal depression measured between 24 and 28 weeks of gestation using the 9-question Patient Health Questionnaire (PHQ-9); data on pregnancy including an ultrasound before 19 weeks of gestation; data on pregnancy outcomes; and data on woman's age, education, parity, weight, height, history of previous illness, prior miscarriage, stillbirth, husband's education, and household socioeconomic data collected during early pregnancy. Using PHQ-9 cutoff score of ≥12, women were categorized into none to mild depression or moderate to moderately severe depression. Using ultrasound data, preterm birth was defined as babies born <37 weeks of gestation. To identify risk ratios (RR) for antenatal depression, unadjusted and adjusted RR and 95% confidence intervals (CI) were calculated using log- binomial model. Log-binomial models were also used for determining the effect of antenatal depression on preterm birth adjusting for potential confounders. Data were analyzed using Stata version 16 (StataCorp LP). RESULTS: About 6% of the women reported moderate to moderately severe depressive symptoms during the antenatal period. A parity of ≥2 and the highest household wealth status were associated with an increased risk of depression. The overall incidence of preterm birth was 13.4%. Maternal antenatal depression was significantly associated with the risk of preterm birth (ARR, 95% CI: 1.34, 1.02-1.74). CONCLUSION: The increased risk of preterm birth in women with antenatal depression in conjunction with other significant risk factors suggests that depression likely occurs within a constellation of other risk factors. Thus, to effectively address the burden of preterm birth, programs require developing and providing integrated care addressing multiple risk factors.

OBJECTIVE: We aimed to rapidly assess the health system impact of COVID-19 in the urban slums of Bangladesh. DESIGN: Setting and participantsA cross-sectional survey among 476 households was conducted during October-December 2020 in five selected urban slums of Dhaka North, Dhaka South and Gazipur City Corporation. In-depth interviews with purposively selected 22 slum dwellers and key informant interviews with 16 local healthcare providers and four policymakers and technical experts were also conducted. OUTCOME MEASURES: Percentage of people suffering from general illness, percentage of people suffering from chronic illness, percentage of people seeking healthcare, percentage of people seeking maternal care, health system challenges resulting from COVID-19. RESULTS: About 12% of members suffered from general illness and 25% reported chronic illness. Over 80% sought healthcare and the majority sought care from informal healthcare providers. 39% of the recently delivered women sought healthcare in 3 months preceding the survey. An overall reduction in healthcare use was reported during the lockdown period compared with prepandemic time. Mismanagement and inefficient use of resources were reported as challenges of health financing during the pandemic. Health information sharing was inadequate at the urban slums, resulting from the lack of community and stakeholder engagement (51% received COVID-19-related information, 49% of respondents knew about the national hotline number for COVID-19 treatment). Shortage of human resources for health was reported to be acute during the pandemic, resulting from the shortage of specialist doctors and uneven distribution of health workforce. COVID-19 test was inadequate due to the lack of adequate test facilities and stigma associated with COVID-19. Lack of strong leadership and stakeholder engagement was seen as the barriers to effective pandemic management. CONCLUSION: The findings of the current study are expected to support the government in tailoring interventions and allocating resources more efficiently and timely during a pandemic.

Infant and child mortality are often used to monitor the progress of national population health programs. The data for this study was collected from selected urban slums where icddr,b has maintained the Health and Demographic Surveillance System (HDSS). Using the HDSS database, 6,666 married women were selected and interviewed in 2018 to collect data on socioeconomic status, pregnancy history and safe motherhood practices. The study examined levels and trends of infant and under-five mortality for three periods: 1990-1999 (Period 1), 2000-2009 (Period 2), and 2010-2018 (Period 3) and examined socio-demographic differentials of infant and under-five mortality for Period 3. From Period 1 to Period 3, under-five mortality declined by 68.2%, with child mortality (1-4 years) declining more than infant mortality (84% vs. 65%). In the regression models for Period 3, infant and under-five mortality were higher for working than non-working mothers (infant: OR = 1.35*, CI: 0.98, 1.86; under-five: OR = 1.34*, CI: 0.99, 1.82), lower for girls than boys (infant: OR = 0.77*, CI: 0.57, 1.03; under-five: OR = 0.77*, CI: 0.58, 1.03), higher for small-size than normal/big-size babies (infant: OR = 4.11***, CI: 3.00, 5.64; under-five: OR = 3.68***, CI: 2.70, 5.02), higher for babies delivered vaginally than by caesarean section (infant: OR = 1.79**, CI: 1.14, 2.97; under-five: OR = 1.87***, CI: 1.21, 2.88), higher for babies delivered with complications than no complication (infant: OR = 2.16***, CI: 1.48, 3.15; under-five: OR = 2.21***, CI: 1.55, 3.18), and higher for babies born after a short (<24 months) birth interval (infant: OR = 1.71*, CI: 0.96, 3.05; under-five: OR = 1.63*, CI: 0.93, 2.86) than firstborns. While substantial progress has been made in reducing under-five and infant mortality, neonatal mortality have declined less slowly. Targeted population health interventions addressing the socio-demographic drivers of infant mortality, with a focus on the urban poor, will help Bangladesh achieve Sustainable Development Goal 3.
RESUMEN
BACKGROUND: The study aimed to assess the health-related quality of life (HRQoL) and its associated factors among urban slum dwellers who migrated from different rural parts of Bangladesh. METHODS: The present study analyzed data from a Migration and Mobility Determinants on Health survey and was conducted in 2017 among 935 migrant slum dwellers of Dhaka city (North & South) and Gazipur City Corporations, as a part of the icddr,b's Urban Health and Demographic Surveillance System (UHDSS). The face-to-face interviews were conducted with the adult population by using a semi-structured questionnaire that included variables related to socio-demographics, migration, occupation, and HRQoL (SF-12). Bivariate and multiple linear regression analyses were performed to determine the factors associated with HRQoL. RESULTS: The mean (±SD) scores of physical component summary (PCS), and mental component summary (MCS) were 57.40 ± 22.73 and 60.77 ± 22.51, respectively. As per multiple regression analysis, lower PCS scores were associated with having older age, being female, and not having any job. Mean MCS scores were significantly lower among participants who reported having older age, not having any job, not working/ less working hours (≤8 h/day), as well as increased work-related stress in the current urban slum. CONCLUSIONS: The findings suggest that available urban social protection programs should include a comprehensive social safety net for the improvement of the slum infrastructure as well as proper health care and risk mitigation plans at workplaces.

BACKGROUND: Competencies represent sets of general abilities and attributes that graduating nurses must acquire. Most nursing programs adopt competency based assessment and training approaches to prepare their students to enter the clinical environment. However, some concern has been raised regarding their interpretation and implementation in everyday clinical training. To operationalize competencies for better use in clinical practice, the Entrustable Professional Activities framework (EPAs) was introduced in 2005 by ten Cate. AIM: The aim of this study is to develop a framework of EPAs for an Undergraduate Nursing Program. METHOD: Through using a participatory action design approach, the participants developed a set of EPAs linked with competencies for an Undergraduate Nursing Program. Thematic analysis was performed, and EPAs framework validity was constructed. RESULT: A total of eight core EPAs were developed and each one was operationalized by a brief description and nested within the related core competency domains. Supervision levels and entrustment decisions were determined. CONCLUSION: The development of EPAs specific to undergraduate nursing programs may offer the opportunity to have standardized language to evaluate students' progress toward competency in nursing. It is recommended to conduct further research to improve the developed EPAs.

Community health workers (CHWs) are key to implementing community-based health interventions and quality can be enhanced by better understanding their lived experiences. The WASH Benefits, Bangladesh trial engaged 540 female CHWs to promote varying health intervention packages. We report on factors influencing their lived experiences during the trial, to aid future recruitment, training and retention of CHWs. Nine focus groups and 18 in-depth interviews were conducted with CHWs. Focus groups and interviews were transcribed and thematic content analysis performed to summarize the results. All CHWs described experiencing positive working conditions and many benefits both socially and financially; these contributed to their retention and job satisfaction. Their honorarium was commonly applied towards their children's education and invested for income generation. CHWs gained self-confidence as women, to move unaccompanied in the community and speak in public. They earned respect from the community and their family members who helped them manage their family obligations during work and were viewed as a resource for advice on health and social issues. Many participated in family decision-making from which they were previously excluded. Health programs should foster a positive experience among their CHWs to aid the recruitment, retention and development of this important human resource.

Observational data suggest maternal handwashing with soap prevents neonatal mortality. We tested the impact of a chlorhexidine-based waterless hand cleansing promotion on the behavior of mothers and other household members. In rural Bangladesh in 2014, we randomized consenting pregnant women to chlorhexidine provision and hand cleansing promotion or standard practices. We compared hand cleansing with chlorhexidine or handwashing with soap before baby care, among mothers and household members in the two groups, and measured chlorhexidine use in the intervention arm. Chlorhexidine was observed in the baby's sleep space in 97% of 130 intervention homes, versus soap in 59% of 128 control homes. Hand cleansing before baby care was observed 5.6 times more frequently among mothers in the intervention arm than in the controls (95% CI = 4.0-7.7). Hand cleansing was significantly more frequently observed in the intervention arm among women other than the mother (RR = 10.9) and girls (RR = 37.0). Men and boys in the intervention arm cleansed hands before 29% and 44% of baby care events, respectively, compared with 0% in the control arm. The median number of grams consumed during the neonatal period was 176 (IQR = 95-305 g), about 7.8 g/day (IQR = 4.2-13.8 g). Promotion of waterless chlorhexidine increased hand cleansing behavior among mothers and other household members. Discrepancy between observed use and measured chlorhexidine consumption suggested courtesy bias in structured observations. A waterless hand cleanser may represent one component of the multimodal strategies to prevent neonatal infections in low-resource settings.

INTRODUCTION: Special cooperation is required among surgeons and anesthetists in airway management during repair of panfacial fractures, due to problems of shared airway and occlusion. Several methods have been proposed for airway management and sequencing of repair of panfacial fractures. The main objective of the current study was to share our experience in the airway management and sequencing of repair of panfacial fractures. METHODS: This was a retrospective study of panfacial fractures in the Kingdom of Saudi Arabia from January 2008 to December 2018. Data collected included demographics, type of airway management, sequence of repair (as primary variables), and outcome of surgery (secondary variable), while surgeon and anesthetic expertise are confounders. Data were analyzed using IBM SPSS Statistics for Windows Version 25 (Armonk, NY, USA: IBM Corp). Results were presented as simple frequencies and descriptive statistics. Pearson Chi-square was used to compare categorical variables such as airway management and sequencing of repair with the panfacial fractures. Statistical significance was set at P ≤ 0.05. RESULTS: Overall, 1057 patients sustained different categories of maxillofacial bone fractures with 23 females and 1034 males (M:F of 46:1). A total of 43 male patients out of 1057 patients had panfacial fractures during the study period, giving a prevalence rate of 4.1%. Only the 43 male patients with panfacial fractures were analyzed. All cases were as a result of motor vehicular accident. Six (13.9%) patients had tracheostomy while 37 (86.1%) patients had submental intubation. "Bottom-up" and "outside-in" approach was used in 33 (76.7%) patients, while "top-bottom" and "inside-out" approach was used in 10 (23.3%) patients. DISCUSSION: Submental intubation was the major airway management of panfacial fracture, and "bottom-up" and "outside-in" approach was the main sequence of repair in our series. These approaches have been mentioned in the literature. CONCLUSION: From our study, victims of pan-facial fractures were found to be exclusively male with MVA as the sole etiological factor. Barring severe head injuries, which may necessitate the use of tracheostomy to sustain breathing over a longer period, submental intubation is extremely reliable as a mode of airway management during surgical treatment of panfacial fractures. The sequencing of repair of panfacial fractures can only be determined according to the case presentation rather than a predetermined one.
RESUMEN
BACKGROUND: The Cholera-Hospital-Based-Intervention-for-7-Days (CHoBI7) is a handwashing with soap and water treatment intervention program delivered by a health promoter bedside in a health facility and through home visits to diarrhea patients and their household members during the 7 days after admission to a health facility. In a randomized controlled trial among cholera patient households in Bangladesh, the 7-day CHoBI7 program resulted in a significant reduction in cholera among household members of cholera patients and sustained improvements in drinking water quality and handwashing with soap practices 12 months post-intervention. In an effort to take this intervention to scale across Bangladesh in partnership with the Bangladesh Ministry of Health and Family Welfare, this study evaluates the feasibility and acceptability of mobile health (mHealth) programs as a low-cost, scalable approach for CHoBI7 program delivery. METHODS: Formative research for the development of the CHoBI7 mHealth intervention included 40 semi-structured interviews, 4 mHealth workshops, 2 group discussions, and a pilot study of 52 households to assess the feasibility and acceptability of the developed mHealth program. Thematic analysis of the interviews and group discussions was conducted by two individuals separately based on emergent themes, and then themes were compared and discussed. RESULTS: A theory- and evidence-based approach using qualitative research methods was implemented to design the CHoBI7 mHealth program. Semi-structured interviews with government stakeholders identified perceptions and preferences for scaling the CHoBI7 mHealth program. Group discussions and semi-structured interviews with diarrhea patients and their family members identified beneficiary perceptions of mHealth and preferences for CHoBI7 mHealth program delivery. mHealth workshops were conducted as an interactive approach to draft and refine mobile message content based on stakeholder preferences. The pilot findings indicate that the CHoBI7 mHealth program has high user acceptability and is feasible to deliver to diarrhea patients that present at health facilities for treatment in Bangladesh. Both text and voice messages were recommended for program delivery. Dr. Chobi, the sender of mHealth messages, was viewed as a credible source of information that could be shared with others. CONCLUSION: This study presents a theory- and evidence-based approach that can be implemented for the development of future water, sanitation, and hygiene mHealth programs in low-resource settings.

RESUMEN
OBJECTIVE: The behavioural effect of large-scale handwashing promotion programmes has been infrequently evaluated, and variation in the effect over time has not been described. We assess the effect of a large-scale handwashing promotion programme on handwashing outcomes in a community setting in Dhaka, Bangladesh. METHODS: We analysed data from a cluster-randomised trial that included three arms: vaccine-and-behaviour-change intervention (VBC), vaccine-only (V) and no intervention (Control). Data collectors randomly selected different subsets of households each month during the study period and assessed: (i) temporal variation in availability of soap and water at handwashing place; (ii) the use of water and soap by participants when asked to demonstrate handwashing, and; (iii) handwashing behaviour according to structured observation. We used log-binomial regression analyses to calculate prevalence ratios (PRs) and 95% confidence intervals and compare outcomes by study arms. RESULTS: Data collectors surveyed 9325 households over 28 months. In VBC, there was a significant positive trend on availability of water and soap from baseline to 9 months after the start of the intervention (P-for-trends <0.001), and no significant trend during months 10-28 (P-for-trend = 0.297). In the entire study period, availability of water and soap was higher in VBC (43%) than in V (23%) (PR = 1.92; CI = 1.72, 2.15) and Control (28%) (PR = 1.53; CI = 1.38, 1.69) households. There were no differences between study arms with regard to use of soap during handwashing demonstrations. Observed handwashing with soap after toilet use was higher in VBC (17%) than in V (8%) (PR = 1.47, CI = 0.58, 3.75) and Control (2%) (PR = 3.47, CI = 0.48, 23.33) groups. At other possible pathogen transmission events, the prevalence of handwashing with soap was ≤3%. CONCLUSION: VBC households maintained soap and water for handwashing, but the prevalence of observed handwashing was low in all study arms. The results underscore the need to strengthen scalable behaviour change approaches.
OBJECTIF: L'effet sur le comportement des programmes de promotion du lavage des mains à grande échelle a été rarement évalué et aucune variation de cet effet dans le temps n'a été décrite. Nous évaluons les effets d'un programme de promotion du lavage des mains à grande échelle sur les résultats dans un cadre communautaire à Dhaka, au Bangladesh. MÉTHODES: Nous avons analysé les données d'un essai randomisé par grappes comprenant 3 groupes: intervention vaccin-changement de comportement (VBC), vaccin uniquement (V) et aucune intervention (contrôle). Les collecteurs de données ont sélectionné au hasard différents sous-ensembles de ménages chaque mois au cours de la période d'étude et ont évalué: 1) la variation temporelle de la disponibilité de savon et d'eau sur le lieu de lavage des mains, 2) l'utilisation d'eau et de savon par les participants lorsqu'on leur a demandé de faire la démonstration du lavage des mains, 3) le comportement du lavage des mains selon une observation structurée. Nous avons utilisé des analyses de régression log-binomiales pour calculer les ratios de prévalence (PR) et les intervalles de confiance à 95%, ainsi que pour comparer les résultats par groupe d'étude. RÉSULTATS: Les collecteurs de données ont interrogé 9325 ménages au cours de 28 mois. Dans le groupe VBC, il y avait une tendance positive significative sur la disponibilité d'eau et de savon de la ligne de base à 9 mois après le début de l'intervention (p-pour-tendances <0,001) et aucune tendance significative au cours des mois 10 à 28 (p-pour- tendance = 0,297). Sur l'ensemble de la période d'étude, la disponibilité en eau et en savon était plus élevée dans le groupe VBC (43%) que dans le groupe V (23%) (PR = 1,92; IC: 1,72 - 2,15) et dans le groupe contrôle (28%) (PR = 1,53; IC: 1,38 - 1,69). Il n'y avait pas de différence entre les groupes d'étude en ce qui concerne l'utilisation de savon lors de démonstrations de lavage des mains. Le lavage des mains observé avec du savon après l'utilisation des toilettes était plus élevé dans le groupe VBC (17%) que dans le groupe V (8%) (PR = 1,47; IC: 0,58 - 3,75) et dans le groupe témoin (2%) (PR = 3,47, IC: 0,48 - 23,33). Lors d'autres événements possibles de transmission d'agents pathogènes, la fréquence du lavage des mains au savon était ≤ 3%. CONCLUSION: Les ménages du groupe VBC ont maintenu du savon et de l'eau pour se laver les mains, mais la prévalence du lavage des mains observé était faible dans tous les groupes de l'étude. Les résultats soulignent la nécessité de renforcer les approches évolutives de changement de comportement.

To explore the consistency in impact evaluation based on reported diarrhea, we compared diarrhea data collected through two different surveys and with observed diarrhea-associated hospitalization for children aged ≤ 5 years from a non-blinded cluster-randomized trial conducted over 2 years in urban Dhaka. We have previously reported that the interventions did not reduce diarrhea-associated hospitalization for children aged ≤ 5 years in this trial. We randomly allocated 90 geographic clusters comprising > 60,000 low-income households into three groups: cholera vaccine only, vaccine plus behavior change (cholera vaccine and handwashing plus drinking water chlorination promotion), and control. We calculated reported diarrhea prevalence within the last 2 days using data collected from two different survey methods. The "census" data were collected from each household every 6 months for updating household demographic information. The "monthly survey" data were collected every month from a subset of randomly selected study households for monitoring the uptake of behavior change interventions. We used binomial regression with a logarithmic link accounting for clustering to compare diarrhea prevalence across intervention and control groups separately for both census and monthly survey data. No intervention impact was detected in the census (vaccine only versus control: 2.32% versus 2.53%; P = 0.49; vaccine plus behavior change versus control: 2.44% versus 2.53%; P = 0.78) or in the vaccine only versus control in the monthly survey (3.39% versus 3.80%; P = 0.69). However, diarrhea prevalence was lower in the vaccine-plus-behavior-change group than control in the monthly survey (2.08% versus 3.80%; P = 0.02). Although the reasons for different observed treatment effects in the census and monthly survey data in this study are unclear, these findings emphasize the importance of assessing objective outcomes along with reported outcomes from non-blinded trials.

PURPOSE: To provide new insights into how protein-surfactant competitive adsorbtion and corresponding surface tension reduction properties at the air-water and oil-water interface are impacted by the type of protein and the associated protein surface rheology. METHOD: Interfacial Rheology was utilized to obtain surface G' and G" as a function of frequency. Force tensiometry was utilized to obtain changes in surface tension as a function of surfactant concentration. The impact on surface properties of two different proteins i.e. BSA and Lysozyme was investigated as a function of surfactant concentration i.e. polysorbates PS 20, PS 80 and Poloxomer (Kolliphor P188). RESULTS: Surface tension and interfacial tension measurements for BSA showed that in mixed BSA/polysorbate surfactant systems, BSA dominates the interfacial behavior at both the air-water and oil-water interfaces, until a high polysorbate concentration of 0.1 mg/ml. At these high polysorbate concentrations a mixed BSA-Polysorbate interfacial layer is formed as corroborated by the surface elasticity values being lower than that of pure BSA but higher than that of pure Polysorbate. For Kolliphor, it was observed that Kolliphor was unable to displace BSA at any concentration. This is corroborated by the high surface elasticity of the BSA which is maintained in the presence of Kolliphor. Surface and interfacial tension measurements for lysozyme show that for mixed lysozyme/polysorbate surfactant systems, the surface tension values are lower than that exhibited by either the lysozyme or the polysorbate surfactants. This potentially indicates the formation of a mixed layer of lysozyme and polysorbate. At the high polysorbate concentrations probed, the surface elasticity values are however closer to that of pure polysorbates, indicating that the mixed layer may be more heavily polysorbate dominated, especially at high polysorbate concentrations. For Kolliphor, the response was similar to that seen in the Kolliphor-BSA system in which the Kolliphor was not able to displace the protein i.e. Lysozyme. CONCLUSIONS: In conclusion, it was seen that competitive adsorption between proteins and common excipient surfactants is dictated by the type of protein and its effective structuring/rigidity at the surface as reflected through surface elasticity and surface tan delta values. BSA was seen to exhibit a higher surface elasticity than lysozyme, and therefore has a more rigid structure and is more competitive at the interface.

We assessed the impact of handwashing promotion on reported respiratory illness as a secondary outcome from among > 60,000 low-income households enrolled in a cluster-randomized trial conducted in Bangladesh. Ninety geographic clusters were randomly allocated into three groups: cholera-vaccine-only; vaccine-plus-behavior-change (handwashing promotion and drinking water chlorination); and control. Data on respiratory illness (fever plus either cough or nasal congestion or breathing difficulty within previous 2 days) and intervention uptake (presence of soap and water at handwashing station) were collected through monthly surveys conducted among a different subset of randomly selected households during the intervention period. We determined respiratory illness prevalence across groups and used log-binomial regression to examine the association between respiratory illness and presence of soap and water in the handwashing station. Results were adjusted for age, gender, wealth, and cluster-randomized design. The vaccine-plus-behavior-change group had more handwashing stations with soap and water present than controls (45% versus 25%; P < 0.001). Reported respiratory illness prevalence was similar across groups (vaccine-plus-behavior-change versus control: 2.8% versus 2.9%; 95% confidence interval [CI]: -0.008, 0.006; P = 0.6; cholera-vaccine-only versus control: 3.0% versus 2.9%; 95% CI: -0.006, 0.009; P = 0.4). Irrespective of intervention assignment, respiratory illness was lower among people who had soap and water present in the handwashing station than among those who did not (risk ratioadjusted: 0.82; 95% CI: 0.69-0.98). With modest uptake of the handwashing intervention, we found no impact of this large-scale intervention on respiratory illness. However, those who actually had a handwashing station with soap and water had less illness. This suggests improving the effectiveness of handwashing promotion in achieving sustained behavior change could result in health benefits.
