Comparison of Cardiovascular Health Profiles Across Population Surveys From 5 High- to Low-Income Countries. CJC Open 2024; 6:582-596. [PMID: 38559335 PMCID: PMC10980894 DOI: 10.1016/j.cjco.2023.11.021] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/05/2023] [Accepted: 11/28/2023] [Indexed: 04/04/2024] Open
Abstract
Background To facilitate the shift from risk-factor management to primordial prevention of cardiovascular disease, the American Heart Association developed guidelines to score and track cardiovascular health (CVH). How the prevalence and trajectories of a high level of CVH across the life course compare among high- and lower-income countries is unknown. Methods Nationally representative survey data with CVH variables (physical activity, cigarette smoking, body mass index, blood pressure, blood glucose, and total cholesterol levels) were identified in Ethiopia, Bangladesh, Brazil, England, and the US for adults (aged 18-69 years and not pregnant). Data were harmonized, and CVH metrics were scored using the American Heart Association guidelines, as high (2), moderate (1), or low (0), with the prevalence of high scores (better CVH) across the life course compared across countries. Results Among 28,092 adults (Ethiopia n = 7686, 55.2% male; Bangladesh n = 6731, 48.4% male; Brazil n = 7241, 47.9% male; England n = 2691, 49.5% male, and the US n = 3743, 50.3% male), the prevalence of high CVH scores decreased as country income level increased. Declining CVH with age was universal across countries, but differences were already observable in those aged 18 years. Excess body weight appeared to be the main driver of poor CVH in higher-income countries, and the prevalence of current smoking was highest in Bangladesh. Conclusions Our findings suggest that CVH decline with age may be universal. Interventions to promote and preserve CVH throughout the life course are needed in all populations, tailored to country-specific time courses of the decline. In countries where the level of CVH remains relatively high, protection of whole societies from risk-factor epidemics may still be feasible.

Exploring the knowledge and practices on road safety measures among motorbikers in Dhaka, Bangladesh: a cross-sectional study. Inj Prev 2023:ip-2023-045071. [PMID: 38050086 DOI: 10.1136/ip-2023-045071] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/08/2023] [Accepted: 10/30/2023] [Indexed: 12/06/2023]
Abstract
INTRODUCTION Road traffic injuries (RTIs), particularly motorbike injuries, are one of the leading causes of death worldwide and have been a serious concern in low- and middle-income countries like Bangladesh. Therefore, this study aimed to assess the level of knowledge and practices on road safety measures among motorbikers in Dhaka, Bangladesh. METHODS This cross-sectional study was conducted from January 2022 to December 2022 among 350 motorbikers of Dhaka city via a series of face-to-face interviews. Motorbikers who regularly ride a motorcycle were interviewed about their road safety knowledge and practices through a two-stage cluster sampling technique. Frequency distribution, independent sample t-test and one-way analysis of variance (ANOVA) were performed in data analysis. RESULTS Out of the 350 motorbikers, only 54.6% had good knowledge and 16.9% had poor knowledge on the signs and safety regulations of roads. Moreover, only 50.6% of respondents followed good practices while 23.4% followed poor practices of road safety measures. One-way ANOVA analysis demonstrates that the average knowledge score was significantly (p<0.05) higher among higher-educated, unmarried and non-smokers. Additionally, higher education level, non-smoking status and being Muslim were significantly (p<0.05) associated with good road safety practices. CONCLUSIONS The overall good knowledge level and practices of road safety measures among the motorbikers was not satisfactory although the majority of them knew individual signs and regulations. Therefore, this study suggests that education and strict enforcement of traffic rules may increase their knowledge and practice behaviour regarding road safety which in turn would minimise traffic injuries and fatalities.

Abstract
Aims With the greatest burden of cardiovascular disease morbidity and mortality increasingly observed in lower-income countries least prepared for this epidemic, focus is widening from risk factor management alone to primordial prevention to maintain high levels of cardiovascular health (CVH) across the life course. To facilitate this, the American Heart Association (AHA) developed CVH scoring guidelines to evaluate and track CVH. We aimed to compare the prevalence and trajectories of high CVH across the life course using nationally representative adult CVH data from five diverse high- to low-income countries. Methods Surveys with CVH variables (physical activity, cigarette smoking, body mass, blood pressure, blood glucose, and total cholesterol levels) were identified in Ethiopia, Bangladesh, Brazil, England, and the United States (US). Participants were included if they were 18-69y, not pregnant, and had data for these CVH metrics. Comparable data were harmonized and each of the CVH metrics was scored using AHA guidelines as high (2), moderate (1), or low (0) to create total CVH scores with higher scores representing better CVH. High CVH prevalence by age was compared creating country CVH trajectories. Results The analysis included 28,092 adults (Ethiopia n=7686, 55.2% male; Bangladesh n=6731, 48.4% male; Brazil n=7241, 47.9 % male; England n=2691, 49.5% male, and the US n=3743, 50.3% male). As country income level increased, prevalence of high CVH decreased (>90% in Ethiopia, >68% in Bangladesh and under 65% in the remaining countries). This pattern remained using either five or all six CVH metrics and following exclusion of underweight participants. While a decline in CVH with age was observed for all countries, higher income countries showed lower prevalence of high CVH already by age 18y. Excess body weight appeared the main driver of poor CVH in higher income countries, while current smoking was highest in Bangladesh. Conclusion Harmonization of nationally representative survey data on CVH trajectories with age in 5 highly diverse countries supports our hypothesis that CVH decline with age may be universal. Interventions to promote and preserve high CVH throughout the life course are needed in all populations, tailored to country-specific time courses of the decline. In countries where CVH remains relatively high, protection of whole societies from risk factor epidemics may still be feasible.

Post-traumatic stress disorders and coping strategies of health professionals during COVID-19 pandemic in Bangladesh: Findings of a countrywide cross-sectional study. THE LANCET REGIONAL HEALTH. SOUTHEAST ASIA 2022; 11:100131. [PMID: 36575773 PMCID: PMC9780642 DOI: 10.1016/j.lansea.2022.100131] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 06/28/2022] [Revised: 11/30/2022] [Accepted: 12/09/2022] [Indexed: 12/24/2022]
Abstract
Background COVID-19 pandemic imposed a devastating effect on the psychological health of health professionals as they worked nonstop to withstand the hardship of the pandemic. The present study intended to determine the post-traumatic stress disorders (PTSD) and coping strategies among health professionals during the COVID-19 pandemic in Bangladesh. Methods This country-wide cross-sectional study was conducted from July to December 2021 among 1394 health professionals (596 physicians, 713 nurses, 85 medical technologists) who served COVID-19 patients at the secondary, tertiary, and specialized government healthcare facilities in Bangladesh and completed at least one month after exposure to COVID-19 patient-care. Data were collected through face-to-face interviews using a semi-structured questionnaire and analyzed by SPSS software. All the ethical issues were maintained strictly. Findings Most of the participants, 877(62∙9%) [95% CI: 60∙3-65∙5], were female, and 327(23∙5%) [95% CI: 21∙3-25∙8] developed PTSD. Females (AOR:1∙42 [95% CI: 1∙083-1∙868] p=0∙011), having an elderly family member (AOR:1∙515 [95% CI: 1∙173-1∙956] p=0∙0014), working in specialized hospitals (AOR:2∙685 [95% CI: 1∙928-3∙739] p<0∙001), and working ≥8 hours/day (AOR:1∙897 [95% CI: 1∙350-2∙666] p=0∙0002) had higher odds of developing PTSD. Most of the participants adopted spiritual approaches 96(29∙4%) [24∙5-34∙6] and distraction by watching TV/YouTube 59(18∙0%) [14∙0-22∙6] as coping strategies. Interpretation The study findings would be helpful for health policymakers and managers to develop comprehensive measures for restoring the mental well-being of health professionals by alleviating PTSD induced by a pandemic like COVID-19. Funding The study got funding from the Directorate General of Medical Education under the Ministry of Health and Family Welfare, Bangladesh.

Abstract
Background: Community Clinics (CC) has been established to provide basic healthcare services at the doorstep of the community people in Bangladesh. Besides health care, government has taken a development program through CC to improve maternal health care with an aim to reduce the maternal mortality. This study was an attempt to find out the role of community women in the utilization and participation of CC management.
Methods: This cross-sectional study was carried out in 32 randomly selected CCs from 16 randomly selected districts. A total of 63 service providers, 2238 service users (patients) and 3285 community members were included as the respondents of this study. For data collection respondents were interviewed face to face by using a pretested questionnaire.
Results: The majority of the service providers of the CC were from the local community, and a higher proportion of them were female (52.4%). The providers provided healthcare services both in CC and at community level. A total of 2238 patients visited the 32 studied CCs per day for getting treatment and significantly a higher proportion of them were female (71.2%). Most of the patients (83.0%) expressed satisfaction with the services provided in the CCs and most of them were female (83.8%). Of the total 3285 respondents, 60.3% were the women from the catchment communities. The activities of the CC were known by all of them (98.3%) and they participated in the management of CC.
Conclusions: The study revealed that because of utilization and participation in the management of CC, the women became an imperative person in the community, thus empowering them in healthcare development.

Abstract
<b><i>Methodology:</i></b> Biochemically confirmed type 2 diabetes mellitus (T2DM) patients (<i>n</i> = 1,114) were recruited from the outpatient department of 2 tertiary care hospitals in Dhaka, Bangladesh. Face-to-face interview was conducted using a semi-structured questionnaire containing sociodemographic parameters and relevant information about depression and diabetes. Biochemical test results and treatment-related information were taken from patients’ records. The Hospital Anxiety and Depression Scale (HADS) was used to screen all patients for psychiatric manifestation. Those diagnosed by HADS were subsequently reassessed using structured clinical interview for DSM-5 Disorders – Clinician Version. T2DM diagnosed at age <40 years were considered as early onset T2DM. Association between age of onset category and depression was assessed using multivariable mixed-effect logistic regression adjusting for random variation of the area of residence and plausible confounders. <b><i>Results:</i></b> Around a third of the participants (32.5%) were diagnosed with T2DM before the age of 40 years. Early onset T2DM patients were found to have 57% increase in the risk of developing depression (OR 1.57; 95% CI 1.13–2.28; <i>p</i> = 0.011) in comparison to those with usual onset T2DM (≥40 years). Among other factors a positive family history for diabetes (OR 1.33; 95% CI 1.03–1.78; <i>p</i> = 0.038), poor glycemic control (OR 1.31; 95% CI 1.03–1.68; <i>p</i> = 0.028), presence of 1, or more diabetic complications (OR 1.37; 95% CI 1.03–1.78; <i>p</i> = 0.011) also showed increased risk of depression. <b><i>Conclusion:</i></b> Early onset T2DM patients are at greater risk of developing depression. The finding is likely to help in setting preventive strategies aiming to reduce the presence of concomitant depression symptoms among diabetes.

Megacities as drivers of national outbreaks: The 2017 chikungunya outbreak in Dhaka, Bangladesh. PLoS Negl Trop Dis 2021; 15:e0009106. [PMID: 33529229 PMCID: PMC7880496 DOI: 10.1371/journal.pntd.0009106] [Citation(s) in RCA: 12] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/29/2020] [Revised: 02/12/2021] [Accepted: 01/04/2021] [Indexed: 01/11/2023] Open
Abstract
BACKGROUND Several large outbreaks of chikungunya have been reported in the Indian Ocean region in the last decade. In 2017, an outbreak occurred in Dhaka, Bangladesh, one of the largest and densest megacities in the world. Population mobility and fluctuations in population density are important drivers of epidemics. Measuring population mobility during outbreaks is challenging but is a particularly important goal in the context of rapidly growing and highly connected cities in low- and middle-income countries, which can act to amplify and spread local epidemics nationally and internationally. METHODS We first describe the epidemiology of the 2017 chikungunya outbreak in Dhaka and estimate incidence using a mechanistic model of chikungunya transmission parametrized with epidemiological data from a household survey. We combine the modeled dynamics of chikungunya in Dhaka, with mobility estimates derived from mobile phone data for over 4 million subscribers, to understand the role of population mobility on the spatial spread of chikungunya within and outside Dhaka during the 2017 outbreak. RESULTS We estimate a much higher incidence of chikungunya in Dhaka than suggested by official case counts. Vector abundance, local demographics, and population mobility were associated with spatial heterogeneities in incidence in Dhaka. The peak of the outbreak in Dhaka coincided with the annual Eid holidays, during which large numbers of people traveled from Dhaka to other parts of the country. We show that travel during Eid likely resulted in the spread of the infection to the rest of the country. CONCLUSIONS Our results highlight the impact of large-scale population movements, for example during holidays, on the spread of infectious diseases. These dynamics are difficult to capture using traditional approaches, and we compare our results to a standard diffusion model, to highlight the value of real-time data from mobile phones for outbreak analysis, forecasting, and surveillance.

Abstract
OBJECTIVES To determine the national prevalence of risk factors of non-communicable diseases (NCD) in the adult population of Bangladesh. DESIGN The study was a population-based national cross-sectional study. SETTING This study used 496 primary sampling units (PSUs) developed by the Bangladesh Bureau of Statistics. The PSUs were equally allocated to each division and urban and rural stratum within each division. PARTICIPANTS The participants were adults aged 18 to 69 years, who were usual residents of the households for at least 6 months and stayed the night before the survey. Out of 9900 participants, 8185 (82.7%) completed STEP-1 and STEP-2, and 7208 took part in STEP-3. PRIMARY AND SECONDARY OUTCOME The prevalence of behavioural, physical and biochemical risk factors of NCD. Data were weighted to generate national estimates. RESULTS Tobacco use was significantly (p<0.05) higher in the rural (45.2%) than the urban (38.8%) population. Inadequate fruit/vegetable intake was significantly (p<0.05) higher in the urban (92.1%) than in the rural (88.9%) population. The mean salt intake per day was higher in the rural (9.0 g) than urban (8.9 g) population. Among all, 3.0% had no, 70.9% had 1 to 2 and 26.2% had ≥3 NCD risk factors. The urban population was more likely to have insufficient physical activity (adjusted OR (AOR): 1.2, 95% CI: 1.2 to 1.2), obesity (AOR: 1.5, 95% CI: 1.5 to 1.5), hypertension (AOR: 1.3, 95% CI: 1.3 to 1.3), diabetes (AOR: 1.6, 95% CI: 1.6 to 1.6) and hyperglycaemia (AOR: 1.1, 95% CI: 1.1 to 1.1). CONCLUSIONS Considering the high prevalence of the behavioural, physical and biochemical risk factors, diverse population and high-risk group targeted interventions are essential to combat the rising burden of NCDs.

Abstract
Diverse risk factors intercede the outcomes of coronavirus disease 2019 (COVID-19). We conducted this retrospective cohort study with a cohort of 1016 COVID-19 patients diagnosed in May 2020 to identify the risk factors associated with morbidity and mortality outcomes. Data were collected by telephone-interview and reviewing records using a questionnaire and checklist. The study identified morbidity and mortality risk factors on the 28th day of the disease course. The majority of the patients were male (64.1%) and belonged to the age group 25-39 years (39.4%). Urban patients were higher in proportion than rural (69.3% vs. 30.7%). Major comorbidities included 35.0% diabetes mellitus (DM), 28.4% hypertension (HTN), 16.6% chronic obstructive pulmonary disease (COPD), and 7.8% coronary heart disease (CHD). The morbidity rate (not-cured) was 6.0%, and the mortality rate (non-survivor) was 2.5%. Morbidity risk factors included elderly (AOR = 2.56, 95% CI = 1.31-4.99), having comorbidity (AOR = 1.43, 95% CI = 0.83-2.47), and smokeless tobacco use (AOR = 2.17, 95% CI = 0.84-5.61). The morbidity risk was higher with COPD (RR = 2.68), chronic kidney disease (CKD) (RR = 3.33) and chronic liver disease (CLD) (RR = 3.99). Mortality risk factors included elderly (AOR = 7.56, 95% CI = 3.19-17.92), having comorbidity (AOR = 5.27, 95% CI = 1.88-14.79) and SLT use (AOR = 1.93, 95% CI = 0.50-7.46). The mortality risk was higher with COPD (RR = 7.30), DM (RR = 2.63), CHD (RR = 4.65), HTN (RR = 3.38), CKD (RR = 9.03), CLD (RR = 10.52) and malignant diseases (RR = 9.73). We must espouse programme interventions considering the morbidity and mortality risk factors to condense the aggressive outcomes of COVID-19.

Abstract
Internet-related problems such as excessive internet use, problematic internet use (PIU), and internet addiction, are becoming increasingly studied among Bangladeshi adult students, but there has been little research among adolescents. In Bangladesh, there has been no research examining the role of parental mediation in their children's internet use. Therefore, the present structured interview study investigated Bangladeshi adolescent PIU and its associated socio-demographics, internet use behaviors, and the parental mediation role among 350 high school students residing in Dhaka. The results showed that 84 of adolescents (24.0%) were classified as having PIU (cut-off score of ≥ 50 on the Internet Addiction Test) and nine adolescents (2.6%) were classified as having a severe dependency on the internet (cut-off score of >80 on the Internet Addiction Test). According to hierarchical regression analysis, significant PIU correlates included lower academic results, both parents' lower education, mother working outside the home, more than four days' weekly internet use, more than two hours daily internet use, and active mediation. Additionally, internet use behaviors (i.e., internet use locations, devices, purposes, and applications) and parental internet mediation dimensions other than active mediation (i.e., restrictive mediation, active mediation internet safety, monitoring, and technical mediation) were significantly related to PIU in t-tests and correlation analysis respectively. However, they were non-significant in the hierarchical regression analysis when included into equation altogether. The present study's findings will be helpful in developing country-level policymaking decisions and facilitating future research in the country.

Efficacy of a single-dose regimen of inactivated whole-cell oral cholera vaccine: results from 2 years of follow-up of a randomised trial. THE LANCET. INFECTIOUS DISEASES 2018; 18:666-674. [PMID: 29550406 DOI: 10.1016/s1473-3099(18)30108-7] [Citation(s) in RCA: 51] [Impact Index Per Article: 8.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Subscribe] [Scholar Register] [Received: 07/26/2017] [Revised: 01/12/2018] [Accepted: 01/15/2018] [Indexed: 11/24/2022]
Abstract
BACKGROUND A single-dose regimen of inactivated whole-cell oral cholera vaccine (OCV) is attractive because it reduces logistical challenges for vaccination and could enable more people to be vaccinated. Previously, we reported the efficacy of a single dose of an OCV vaccine during the 6 months following dosing. Herein, we report the results of 2 years of follow-up. METHODS In this placebo-controlled, double-blind trial done in Dhaka, Bangladesh, individuals aged 1 year or older with no history of receipt of OCV were randomly assigned to receive a single dose of inactivated OCV or oral placebo. The primary endpoint was a confirmed episode of non-bloody diarrhoea for which the onset was at least 7 days after dosing and a faecal culture was positive for Vibrio cholerae O1 or O139. Passive surveillance for diarrhoea was done in 13 hospitals or major clinics located in or near the study area for 2 years after the last administered dose. We assessed the protective efficacy of the OCV against culture-confirmed cholera occurring 7-730 days after dosing with both crude and multivariable per-protocol analyses. This trial is registered at ClinicalTrials.gov, number NCT02027207. FINDINGS Between Jan 10, 2014, and Feb 4, 2014, 205 513 people were randomly assigned to receive either vaccine or placebo, of whom 204 700 (102 552 vaccine recipients and 102 148 placebo recipients) were included in the per-protocol analysis. 287 first episodes of cholera (109 among vaccine recipients and 178 among placebo recipients) were detected during the 2-year follow-up; 138 of these episodes (46 in vaccine recipients and 92 in placebo recipients) were associated with severe dehydration. The overall incidence rates of initial cholera episodes were 0·22 (95% CI 0·18 to 0·27) per 100 000 person-days in vaccine recipients versus 0·36 (0·31 to 0·42) per 100 000 person-days in placebo recipients (adjusted protective efficacy 39%, 95% CI 23 to 52). The overall incidence of severe cholera was 0·09 (0·07 to 0·12) per 100 000 person-days versus 0·19 (0·15 to 0·23; adjusted protective efficacy 50%, 29 to 65). Vaccine protective efficacy was 52% (8 to 75) against all cholera episodes and 71% (27 to 88) against severe cholera episodes in participants aged 5 years to younger than 15 years. For participants aged 15 years or older, vaccine protective efficacy was 59% (42 to 71) against all cholera episodes and 59% (35 to 74) against severe cholera. The protection in the older age groups was sustained throughout the 2-year follow-up. In participants younger than 5 years, the vaccine did not show protection against either all cholera episodes (protective efficacy -13%, -68 to 25) or severe cholera episodes (-44%, -220 to 35). INTERPRETATION A single dose of the inactivated whole-cell OCV offered protection to older children and adults that was sustained for at least 2 years. The absence of protection of young children might reflect a lesser degree of pre-existing natural immunity in this age group.

Abstract
Unsafe food is linked to the deaths of an estimated two million people annually. Food containing harmful agents is responsible for more than 200 diseases ranging from diarrhoea to cancers. A one-sample pilot intervention study was conducted to evaluate the role of courtyard counselling meetings as the means of intervention for improving food safety knowledge and practices among household food handlers in a district of Bangladesh. The study was conducted in three phases: a baseline survey, the intervention and an end-line survey between April and November 2015 where 194 food handlers took part. Data were collected through observations and face-to-face interviews. The mean age of the respondents was 38.8 (±12.4) years, all of whom were females. Hand washing before eating, and washing utensils with soap were significantly improved at the end-line in comparison to the baseline (57% vs. 40% and 83% vs. 69%, respectively). Hand washing with soap was increased by 4%. The mean score of food handling practices was significantly increased after the intervention (20.5 vs. 22.1; P<0.001). However, hand washing after use of toilet was unchanged after the intervention (75% vs.76%). Knowledge about safe food and the necessity of thorough cooking were significantly increased after the intervention (88% from 64% and 34% from 21%, respectively). Mean scores of knowledge and practice on food safety were significantly increased by 1.9 and 1.6, respectively after the one month intervention. Thus this food safety education in rural communities should be scaled up and, indeed, strengthened using the courtyard counselling meetings in Bangladesh.

Abstract
The risk factor profiles, management and outcome have significant difference between stroke subsets. Aim of this study was to investigate the risk for the two most common subtypes of stroke in Bangladeshi population. Seventy cases of hemorrhagic stroke (HS) and 105 cases of confirmed ischemic stroke (IS) were recruited from the Shaheed Suhrawardy Medical College Hospital (ShSMCH) and Dhaka Medical College Hospital between January-June 2011. Total 171 age, sex matched controls were selected from the hospitalized patients with history of no stroke ever. Average hemorrhagic stroke patients (60.4±12.3 years) were younger than both ischemic strokes (63.5±13 years). Family history of premature cardiovascular death was found more in HS patients (p=0.001). Multivariate logistic regression showed, in IS model less fruit consumption (OR 4.6), table salt intake (OR 8.15), psychosocial stress (OR 3.5), abnormal ECG (OR 3.6) and Increased WHR (OR 6.9) appeared as significant predictors adjusted for all potential candidate confounders. In HS model less fruit consumption (OR 5.0), table salt intake (OR 9.9), Stress (OR 4.1), family history of cardiovascular disease (CVD) death (OR 11.3), hypertension (OR 43), aspirin intake (OR 4.5) and increased WHR (OR 3.7) remained as significant predictors.

Abstract
BACKGROUND Cholera is endemic in Bangladesh with epidemics occurring each year. The decision to use a cheap oral killed whole-cell cholera vaccine to control the disease depends on the feasibility and effectiveness of vaccination when delivered in a public health setting. We therefore assessed the feasibility and protective effect of delivering such a vaccine through routine government services in urban Bangladesh and evaluated the benefit of adding behavioural interventions to encourage safe drinking water and hand washing to vaccination in this setting. METHODS We did this cluster-randomised open-label trial in Dhaka, Bangladesh. We randomly assigned 90 clusters (1:1:1) to vaccination only, vaccination and behavioural change, or no intervention. The primary outcome was overall protective effectiveness, assessed as the risk of severely dehydrating cholera during 2 years after vaccination for all individuals present at time of the second dose. This study is registered with ClinicalTrials.gov, number NCT01339845. FINDINGS Of 268,896 people present at baseline, we analysed 267,270: 94,675 assigned to vaccination only, 92,539 assigned to vaccination and behavioural change, and 80,056 assigned to non-intervention. Vaccine coverage was 65% in the vaccination only group and 66% in the vaccination and behavioural change group. Overall protective effectiveness was 37% (95% CI lower bound 18%; p=0·002) in the vaccination group and 45% (95% CI lower bound 24%; p=0·001) in the vaccination and behavioural change group. We recorded no vaccine-related serious adverse events. INTERPRETATION Our findings provide the first indication of the effect of delivering an oral killed whole-cell cholera vaccine to poor urban populations with endemic cholera using routine government services and will help policy makers to formulate vaccination strategies to reduce the burden of severely dehydrating cholera in such populations.

Abstract
Not all cases of rheumatic fever (RF) end up as rheumatic heart disease (RHD). The fact raises the possibility of existence of a subgroup with characteristics that prevent RF patients from developing the RHD. The present study aimed at exploring the risk factors among patients with RHD. The study assessed the risk of RHD among people both with and without RF. In total, 103 consecutive RHD patients were recruited as cases who reported to the National Centre for Control of Rheumatic Fever and Heart Disease, Dhaka, Bangladesh. Of 309 controls, 103 were RF patients selected from the same centre, and the remaining 206 controls were selected from Shaheed Suhrawardy Medical College Hospital, who got admitted for other non-cardiac ailments. RHD was confirmed by auscultation and colour Doppler echocardiography. RF was diagnosed based on the modified Jones criteria. An unadjusted odds ratio was generated for each variable, with 95% confidence interval (CI), and only significant factors were considered candidate for multivariate analysis. Three separate binary logistic regression models were generated to assess the risk factors of RF, risk factors of RHD compared to non-rheumatic control patients, and risk factors of RHD compared to control with RF. RF and RHD shared almost a similar set of risk factors in the population. In general, age over 19 years was found to be protective of RF; however, age of the majority (62.1%) of the RHD cases was over 19 years. Women [odds ratio (OR) = 2.2, 95% CI 1.1-4.3], urban resident (OR = 3.1, 95% CI 1.2-8.4), dwellers in brick-built house (OR = 3.6, 95% CI 1.6-8.1), having > 2 siblings (OR = 3.1, 95% CI 1.5- 6.3), offspring of working mothers (OR = 7.6, 95% CI 2.0-24.2), illiterate mother (OR = 2.6, 95% CI 1.2-5.8), and those who did not brush after taking meals (OR = 2.5, 95% CI 1.0-6.3) were more likely to develop RF. However, more than 5 members in a family showed a reduced risk of RF. RHD shared almost a similar set of factors in general. More than three people sharing a room also showed an increased risk of RHD (OR = 1.9, 95% CI 1.0-3.4), in addition to the risk factors of RF. Multivariate model also assessed the factors that may perpetuate RHD among RF patients. Overcrowding (OR = 2.4, 95% CI 1.2-4.7) and illiteracy (OR = 2.4, 95% CI 1.1-5.2) posed the risk of RHD in the RF patients. The study did not find new factors that might pose an increased risk, rather looked for the documented risk factors and how these operate in the population of Bangladesh.

Abstract
This prospective study included 50 patients receiving anterior cervical discectomy and fusion (ACDF) was conducted at Mymensingh Medical College Hospital, Mymensingh, Bangladesh. The study period was 1st July 2006 to 30th June 2010. This study was done to see the functional outcome of surgery in relation to duration of symptoms and age of the patient. The clinical information and relevant imaging of 50 consecutive patients, 41 male and 9 female, was reviewed at 1 year after surgery. All surgery was performed at no more than 2 contiguous levels, by one surgeon. After anterior discectomy alone, or combined with posterior vertebral body margin osteophytectomy, anterior bone grafting was performed at each level using a tricortical autogenous iliac crest bone block inserted under compression. All surgery was completed without internal fixation. A postoperative semirigid cervical collar was prescribed for 2 months. In 50 patients, there were 4 pseudarthroses (8%). Only 4% of the 50 patients had pain related to the donor site. The functional outcome was excellent to good (87.5%) when duration of symptoms less than 1 year and outcome was excellent to good (85.29%) when the age less than 50 years. These results tend to confirm published reports of most expected outcome related to young age and short duration of symptoms. Patients with technically successful fusions were less likely to have postoperative neck pain. Donor site pain was not a significant postoperative complication. ACDF is a safe, cheap and effective procedure for cervical spondylosis. In this series no major operative complications have occurred. No extra expenditure for plate and screw in this procedure.

Abstract
Subdural empyema is a known disease entity; however, calcified subdural empyema is uncommon. The authors present a case of an 11-year-old boy in whom there was diagnosed a chronic calcified subdural empyema 10 years after an attack of meningitis. The patient had suffered from generalized tonic clonic seizures occurring 2-6 times in a month. A large fronto-temporo-parietal craniotomy was carried out and the subdural empyema filled with numerous uncharacteristic tissue fragments with thick pus together with the partially calcified and ossified capsule was removed. The empyema mass was found to be sterile for bacteria. After the operation, no epileptic seizure occurred and the boy is on sodium valporate. We must emphasize the unusual occurrence of the chronic subdural empyema presenting with calcification-ossification and large size as observed in our case.

Abstract
Obesity in pregnancy remains a significant health problem that result in physiological, emotional, social and economic consequences on woman, their families and society. Obesity is considered one of the nutritional problems complicating pregnancy in our country. This study was conducted in antenatal clinic at out patient department of Obstetrics & Gynecology, BIRDEM Hospital, one of the countries largest tertiary level hospitals, during January 2007 to December 2008. During the study period of two years, a total no. of 100 cases were enrolled in two groups. Out of this 50 were control and 50 were over weight and obese. In this study, Mean of height, weight and BMI of the over weight and obese group were 5.21±0.21, 79.35±13.66, 32.36±4.76 respectively. The Mean of birth weight, APGAR score after 1 min and after 5 min of the over weight and obese group were 3.07±0.75, 7.10±1.11, 9.92±0.98 respectively and in normal weight group were 2.74±0.55, 7.40±1.56, 9.92±1.83 respectively. There was significant difference in birth weight, APGAR score after 1 min between the groups (p<0.05) but there was no significant difference in APGAR score after 5 min between groups (p>0.05). Regarding the fetal outcome in this study, 20% of the over weight and obese group delivered macrosomic baby in comparison to only 4% in the normal weight group. On the other hand 46% of the case group had to refer their babies to the neonatal unit in comparison to only 12% in the control group. Gestational Diabetes Mellitus (GDM) (46%) and Preeclampsia (44%) developed more in obese group. Eighty eight (88%) of obese and overweight mother experienced in caesarean delivery. Asphyxia, Respiratory Distress Syndrome (RDS), congenital anomaly and prenatal death were more in the over weight and obese group than normal weight group. Thus, overweight and obesity has got significant deleterious effect on maternal and perinatal outcomes of pregnancy.
