Dengue outbreak 2019: clinical and laboratory profiles of dengue virus infection in Dhaka city.

BACKGROUND: Dengue fever has been one of the most common mosquito-transmitted diseases in the world, affecting more than 128 countries in both tropical and subtropical regions. Bangladesh has been sufferring from dengue outbreaks almost annually since 2000, and in 2019, Bangladesh faced the worst outbreak of dengue to date. This study aimed to provide clinical and biochemical profiles of Bangladesh's dengue-infected patients. METHODS: This cross-sectional study was conducted from August through December 2019 in three tertiary private hospitals in Dhaka, Bangladesh. We collected information on demographic data, clinical characteristics, and laboratory profiles for 542 confirmed hospitalized acute dengue cases using a structured questionnaire. RESULTS: The average age of the enrolled patients was 26.15 years, and about 50% of patients belonged to the age group of 20-40 years. The most frequent among the prevalent clinical symptoms were fever (93.1%), abdominal pain (29.5%), skin rash (25.3%), and diarrhea (19.7%). 316 patients had some complications, such as breathing problems (41.4%), pleural effusion (38.9%), gum bleeding (11.1%), etc. More than 90% of the patients showed seropositivity for the DENV-NS1 antigen. CONCLUSIONS: Over the last couple of years, dengue fever has become a major health issue for Bangladesh. To reduce the burden of this disease, timely diagnosis and prompt treatment are necessary. This analysis thus yields the clinical features, laboratory profiles, and seropositivity test results of dengue patients from Bangladesh. The research results may help clinicians understand the circumstantial diagnosis of dengue patients and facilitate early intervention

Neonatal mortality within 24 hours of birth in six low- and lower-middle-income countries

OBJECTIVE: To assess the rates, timing and causes of neonatal deaths and the burden of stillbirths in rural Uttar Pradesh, India. We discuss the implications of our findings for neonatal interventions. METHODS: We used verbal autopsy interviews to investigate 1048 neonatal deaths and stillbirths. FINDINGS: There were 430 stillbirths reported, comprising 41% of all deaths in the sample. Of the 618 live births, 32% deaths were on the day of birth, 50% occurred during the first 3 days of life and 71% were during the first week. The primary causes of death on the first day of life (i.e. day 0) were birth asphyxia or injury (31%) and preterm birth (26%). During days 1–6, the most frequent causes of death were preterm birth (30%) and sepsis or pneumonia (25%). Half of all deaths caused by sepsis or pneumonia occurred during the first week of life. The proportion of deaths attributed to sepsis or pneumonia increased to 45% and 36% during days 7–13 and 14–27, respectively. CONCLUSION: Stillbirths and deaths on the day of birth represent a large proportion of perinatal and neonatal deaths, highlighting an urgent need to improve coverage with skilled birth attendants and to ensure access to emergency obstetric care. Health interventions to improve essential neonatal care and care-seeking behavior are also needed, particularly for preterm neonates in the early postnatal period

Association between place of delivery, assistance during delivery and fistula occurrence in Afghanistan

Background: Obstetric fistula is one of themost serious and devastating childbirth-related injuries women suffer worldwide. This study investigated the association between delivery characteristics and the occurrence of obstetric fistula in Afghanistan. Methods: The study analysed data from the 2015 Afghanistan Demographic and Health Survey. The association between place of delivery and assistance during delivery with experience of fistula symptoms was investigated by fitting two binary logistic regression models. Results: Findings from this study revealed that 23.4% of the women surveyed ever heard about obstetric fistula and 3% reported symptoms of fistula. Women whose deliveries were assisted by traditional birth attendants were significantly more likely to experience fistula compared with those whose deliveries were assisted by doctors. Similarly, women whose deliveries were assisted by others were significantly more likely to experience fistula compared with women whose deliveries were assisted by doctors. Regarding place of delivery, women whose deliveries took place at a government hospital were less likely to experience fistula compared with those whose deliveries took place at home. Conclusions: This study highlights the importance of skilled delivery in reducing the risk for obstetric fistula among women in Afghanistan. Therefore, it is important for the various stakeholders in Afghanistan's healthcare delivery system, including healthcare providers, local authorities and international non-governmental organisations, to collaborate and institute measures that will promote health facility deliveries and improve access to skilled delivery

The role of age, ethnicity and environmental factors in modulating malaria risk in Rajasthali, Bangladesh

Background: Malaria is endemic in the Rajasthali region of the Chittagong Hill Tracts in Bangladesh and the Rajasthali region is the most endemic area of Bangladesh. Quantifying the role of environmental and socioeconomic factors in the local spatial patterns of malaria endemicity can contribute to successful malaria control and elimination. This study aimed to investigate the role of environmental factors on malaria risk in Rajasthali and to quantify the geographical clustering in malaria risk unaccounted by these factors

COVID-19 vaccination coverage is extremely low among older population in Bangladesh : findings from a cross-sectional study

This cross-sectional study was conducted in September 2021 among 1,045 Bangladeshi older adults aged 60 years or above to explore the COVID-19 vaccination coverage and its associated factors. We used a semi-structured questionnaire to collect data on participants’ sociodemographic and lifestyle characteristics, and COVID-19 related information (selected based on an extensive literature review). A multinomial logistic regression model was used to identify the factors independently associated with vaccine receipt. Nearly, two-thirds of the participants (64.5%) were unvaccinated and 12.5% received a single dose. Among the unvaccinated, approximately 94% reported that there was a problem in accessing the vaccine. We found that participants with formal schooling had 42% lower risk of being unvaccinated (RRR (Relative Risk Ratio) = 0.58, 95% CI 0.42–0.80) or 39% lower risk of receiving a single dose (RRR = 0.61, 95% CI 0.39–0.96) than the participants having no formal schooling. The middle family monthly income groups had 65% higher risk (RRR = 1.65, 95% CI 1.17–2.32) and rural participants had 84% higher risk (RRR = 1.84, 95% CI 1.26–2.70) of not receiving vaccines compared to their counterparts. Also, the participants with non-communicable chronic conditions had a significantly lower risk of being unvaccinated (RRR = 0.49, 95% CI 0.35–0.68) or receiving a single dose (RRR = 0.49, 95% CI 0.31–0.77) compared to their counterparts. This finding may help strengthen the existing efforts to maximize vaccine coverage among older populations in Bangladesh and reach herd immunity to break the transmission chain and gain greater overall population protection more rapidly

Neonatal mortality within 24 hours of birth in six low- and lower-middle-income countries.

Objective: To estimate neonatal mortality, particularly within 24 hours of birth, in six low- and lower-middle-income countries. Methods: We analysed epidemiological data on a total of 149 570 live births collected between 2007 and 2013 in six prospective randomized trials and a cohort study from predominantly rural areas of Bangladesh, Ghana, India, Pakistan, the United Republic of Tanzania and Zambia. The neonatal mortality rate and mortality within 24 hours of birth were estimated for all countries and mortality within 6 hours was estimated for four countries with available data. The findings were compared with published model-based estimates of neonatal mortality. Findings: Overall, the neonatal mortality rate observed at study sites in the six countries was 30.5 per 1000 live births (range: 13.6 in Zambia to 47.4 in Pakistan). Mortality within 24 hours was 14.1 per 1000 live births overall (range: 5.1 in Zambia to 20.1 in India) and 46.3% of all neonatal deaths occurred within 24 hours (range: 36.2% in Pakistan to 65.5% in the United Republic of Tanzania). Mortality in the first 6 hours was 8.3 per 1000 live births, i.e. 31.9% of neonatal mortality. Conclusion: Neonatal mortality within 24 hours of birth in predominantly rural areas of six low- and lower-middle-income countries was higher than model-based estimates for these countries. A little under half of all neonatal deaths occurred within 24 hours of birth and around one third occurred within 6 hours. Implementation of high-quality, effective obstetric and early newborn care should be a priority in these settings

Incidence and risk factors of neonatal infections in a rural Bangladeshi population: a community-based prospective study

Background: Infections cause about one fifth of the estimated 2.7 million annual neonatal deaths worldwide. Population-based data on burden and risk factors of neonatal infections are lacking in developing countries, which are required for the appropriate design of effective preventive and therapeutic interventions in resource-poor settings. Methods: We used data from a community-based cluster-randomized trial conducted to evaluate the impact of two umbilical cord cleansing regimens with chlorhexidine solution on neonatal mortality and morbidity in a rural area of Sylhet District in Bangladesh. Newborns were assessed four times in the first 9 days of life by trained community health workers (CHWs) using a WHO IMCI-like clinical algorithm. Cumulative incidence of the first episode of infections in the first 9 days of life was estimated using survival analysis technique accounting for survival bias and competing risk of death before the occurrence of infection. A multivariable generalized estimating equation log-binomial regression model was used to identify factors independently associated with infections. Results: Between 2007 and 2009, 30,267 newborns who received at least one postnatal assessment visit by a CHW within the first 9 days of life were included in this study. Cumulative incidence of infections in the first 9 days of life was 14.5% (95% CI 14.1\u201314.9%). Significant risk factors included previous child death in the family [RR 1.10 (95% CI 1.02\u20131.19)]; overcrowding [RR 1.14 (95% CI 1.04\u20131.25)]; home delivery [RR 1.86 (95% CI 1.58\u20132.19)]; unclean cord care [RR 1.15 (95% CI 1.03\u20131.28)]; multiple births [RR 1.34 (95% CI 1.15\u20131.56)]; low birth weight [reference: 65 2500 g, RR (95% CI) for < 1500, 1500\u20131999, and 2000\u20132499 g were 4.69 (4.01\u20135.48), 2.15 (1.92\u20132.42), and 1.15 (1.07\u20131.25) respectively]; and birth asphyxia [RR 1.65 (1.51\u20131.81)]. Higher pregnancy order lowered the risk of infections in the study population [compared to first pregnancy, RR (95% CI) for second, third, and 65 fourth pregnancy babies were 0.93 (0.85\u20131.02), 0.88 (0.79\u20130.97), and 0.79 (0.71\u20130.87), respectively]. Conclusion: Neonatal infections and associated deaths can be reduced by identifying and following up high-risk mothers and newborns and promoting facility delivery and clean cord care in resource-poor countries like Bangladesh where the burden of clinically ascertained neonatal infections is high. Further research is needed to measure the burden of infections in the entire neonatal period, particularly in the second fortnight and its association with essential newborn care. Trial registration: NCT00434408. Registered February 9, 2007

Factors associated with the intention of telehealth service utilization among Bangladeshi people: a cross-sectional study [version 2; peer review: 2 approved]

Background Telehealth is comprised of telecommunications and electronic information systems to support and maintain long-distance healthcare services. Although it has not been thoroughly explored, the intention of using the service among the general public is critical to its success. We investigated the factors associated with the intention to utilize telehealth services among the general population of Bangladesh. Methods This cross-sectional study was conducted between May 22, 2021 and June 15, 2021 in Bangladesh, where the total number of participants was 1038. The Pearson chi-square test and Kruskal-Wallis H tests were used to examine the unadjusted relationship between the explanatory variables and the intention to use telehealth services. A multinomial logistic regression model was fitted to determine the adjusted association. Shapiro-Wilk tests were used to check the normality of continuous data. Data were processed and analyzed by software STATA-16. Results The probability of utilizing the service increased significantly with increasing knowledge, perceived benefit, and predisposition levels among respondents. However, when perceived concern increased, the likelihood of utilizing the service dropped significantly. Age, marital status, educational status, profession, residence, and perceived health status were significantly associated with the participants’ intention to utilize the telehealth service. Conclusions The influencing aspects of telehealth service utilization should be recognized by the respective authorities. Possible activities to enhance usability among people are also recommended

Risk factors associated with clinical malaria episodes in Bangladesh: A longitudinal study

Malaria is endemic to Bangladesh. In this longitudinal study, we used hydrologic, topographic, and socioeconomic risk factors to explain single and multiple malaria infections at individual and household levels. Malaria incidence was determined for 1,634 households in 54 villages in 2009 and 2010. During the entire study period 21.8% of households accounted for all (n = 497) malaria cases detected; 15.4% of households had 1 case and 6.4% had ≥2 cases. The greatest risk factors for malaria infection were low bed net ratio per household, house construction materials (wall), and high density of houses. Hydrologic and topographic factors were not significantly associated with malaria risk. This study identifies stable malaria hotspots and risk factors that should be considered for cost-effective targeting of malaria interventions that may contribute to potential elimination of malaria in Bangladesh.
