Pattern and risk factors of acute poisoning in a tertiary hospital of Central Bangladesh

Objective: Acute poisoning is a common cause of hospital admission in Bangladesh. But, risk factors and characteristics of victims of different modes of poisoning have not been evaluated for possible intervention strategies. So, in this study we aimed to describe the pattern of acute poisoning in central Bangladesh as well as identifying risk factors for various mode of poisoning. Methods: A prospective observational study was undertaken in Dhaka Medical College Hospital in 2015. Consenting adult acute poisoning victims were included as study subjects. A pretested structured case record form was used to systematically record the cases. The poisoning cases were defined by clinical toxidrome (sympathomimetic, antimuscarinic, opioids, cholinergic, sedative, etc) during acute presentation with suspected poisoning and groups accordingly. SPSS 20 was used for data analysis and statistical tests including mean ± standard division (SD), percentage, t test and chi-square were used accordingly. Results: Total poisoning cases were 1155. Suicidal (62.25%, n = 719), commuter poisoning (24.16%, n = 279) and accidental poisoning (12.38%, n = 143) were main types of poisoning. Risk factors of suicidal poisoning were young females of 11 to 30 years, married, housewives and students (P < 0.0001). Stressful relationship was the commonest reason of suicidal poisoning. Pesticides and sedatives were frequently chosen for easy availability. Commuter poisoning was common in males and urban areas (P < 0.0001). Accidental poisoning was more in males and rural areas (P < 0.0001) and snake envenomation was the main cause. Conclusion: Poisoning burden is high in central Bangladesh. Identified risk factors will help develop poisoning prevention strategies

Evaluation of feasibility phase of adaptive version of locally made bubble continuous positive airway pressure oxygen therapy for the treatment of COVID-19 positive and negative adults with severe pneumonia and hypoxaemia

BACKGROUND: Bubble continuous positive airway pressure (bCPAP) oxygen therapy has been shown to be safe and effective in treating children with severe pneumonia and hypoxaemia in Bangladesh. Due to lack of adequate non-invasive ventilatory support during coronavirus disease 2019 (COVID-19) crisis, we aimed to evaluate whether bCPAP was safe and feasible when adapted for use in adults with similar indications.METHODS: Adults (18-64 years) with severe pneumonia and moderate hypoxaemia (80 to &lt;90% oxygen saturation (SpO 2) in room air) were provided bCPAP via nasal cannula at a flow rate of 10 litres per minute (l/min) oxygen at 10 centimetres (cm) H 2O pressure, in two tertiary hospitals in Dhaka, Bangladesh. Qualitative interviews and focus group discussions, using a descriptive phenomenological approach, were performed with patients and staff (n = 39) prior to and after the introduction (n = 12 and n = 27 respectively) to understand the operational challenges to the introduction of bCPAP. RESULTS: We enrolled 30 adults (median age 52, interquartile range (IQR) 40-60 years) with severe pneumonia and hypoxaemia and/or acute respiratory distress syndrome (ARDS) irrespective of coronavirus disease 2019 (COVID-19) test results to receive bCPAP. At baseline mean SpO 2 on room air was 87% (±2) which increased to 98% (±2), after initiation of bCPAP. The mean duration of bCPAP oxygen therapy was 14.4 ± 24.8 hours. There were no adverse events of note, and no treatment failure or deaths. Operational challenges to the clinical introduction of bCPAP were lack of functioning pulse oximeters, difficult nasal interface fixation among those wearing nose pin, occasional auto bubbling or lack of bubbling in water-filled plastic bottle, lack of holder for water-filled plastic bottle, rapid turnover of trained clinicians at the hospitals, and limited routine care of patients by hospital clinicians particularly after official hours. DISCUSSION: If the tertiary hospitals in Bangladesh are supplied with well-functioning good quality pulse oximeters and enhanced training of the doctors and nurses on proper use of adapted version of bCPAP, in treating adults with severe pneumonia and hypoxaemia with or without ARDS, the bCPAP was found to be safe, well tolerated and not associated with treatment failure across all study participants. These observations increase the confidence level of the investigators to consider a future efficacy trial of adaptive bCPAP oxygen therapy compared to WHO standard low flow oxygen therapy in such patients.CONCLUSION: s Although bCPAP oxygen therapy was found to be safe and feasible in this pilot study, several challenges were identified that need to be taken into account when planning a definitive clinical trial.</p

Perceptions about Telemedicine among Populations with Chronic Diseases amid COVID-19: Data from a Cross-Sectional Survey

Chronic diseases, including non-communicable diseases (NCDs), have arisen as a severe threat to health and socio-economic growth. Telemedicine can provide both the highest level of patient satisfaction and the lowest risk of infection during a pandemic. The factors associated with its usage and patient adherence are not visible in Bangladesh's resource-constrained settings. Therefore, this study aimed to identify perceptions about telemedicine among populations with chronic diseases amid the COVID-19 pandemic. A closed-ended self-reported questionnaire was created, and the questionnaire was written, reviewed, and finalized by a public health investigator, a psychiatrist, and an epidemiologist. The data for this study were collected from individuals using simple random sampling and snowball sampling techniques. Ethics approval was granted, and written/verbal consent was taken before interviews. Most of the participants showed a positive attitude towards telemedicine. People aged 35-54 years old and a higher level of education were less frequently associated with willingness to receive telemedicine services for current chronic disease (WRTCCD) than their counterparts. People living in urban areas and lower-income participants were more strongly associated with WRTCCD. Additionally, people who did not lose their earnings due to the pandemic were less strongly associated with WRTCCD. However, the main strength of this research is that it is a broad exploration of patient interest in several general forms of telehealth. In Bangladesh, there are many opportunities for telemedicine to be integrated into the existing healthcare system, if appropriate training and education are provided for healthcare professionals

Construction of copy number variation landscape and characterization of associated genes in a Bangladeshi cohort of neurodevelopmental disorders

Introduction: Copy number variations (CNVs) play a critical role in the pathogenesis of neurodevelopmental disorders (NDD) among children. In this study, we aim to identify clinically relevant CNVs, genes and their phenotypic characteristics in an ethnically underrepresented homogenous population of Bangladesh. Methods: We have conducted chromosomal microarray analysis (CMA) for 212 NDD patients with male to female ratio of 2.2:1.0 to identify rare CNVs. To identify candidate genes within the rare CNVs, gene constraint metrics [i.e., “Critical-Exon Genes (CEGs)”] were applied to the population data. Autism Diagnostic Observation Schedule-Second Edition (ADOS-2) was followed in a subset of 95 NDD patients to assess the severity of autism and all statistical tests were performed using the R package. Results: Of all the samples assayed, 12.26% (26/212) and 57.08% (121/212) patients carried pathogenic and variant of uncertain significance (VOUS) CNVs, respectively. While 2.83% (6/212) patients’ pathogenic CNVs were found to be located in the subtelomeric regions. Further burden test identified females are significant carriers of pathogenic CNVs compared to males (OR = 4.2; p = 0.0007). We have observed an increased number of Loss of heterozygosity (LOH) within cases with 23.85% (26/109) consanguineous parents. Our analyses on imprinting genes show, 36 LOH variants disrupting 69 unique imprinted genes and classified these variants as VOUS. ADOS-2 subset shows severe social communication deficit (p = 0.014) and overall ASD symptoms severity (p = 0.026) among the patients carrying duplication CNV compared to the CNV negative group. Candidate gene analysis identified 153 unique CEGs in pathogenic CNVs and 31 in VOUS. Of the unique genes, 18 genes were found to be in smaller (<1 MB) focal CNVs in our NDD cohort and we identified PSMC3 gene as a strong candidate gene for Autism Spectrum Disorder (ASD). Moreover, we hypothesized that KMT2B gene duplication might be associated with intellectual disability. Conclusion: Our results show the utility of CMA for precise genetic diagnosis and its integration into the diagnosis, therapy and management of NDD patients

National Guideline of Rabies Prophylaxis-2010

Background: Rabies has been the subject of fear ever since the disease was recognized. Worldwide the number of deaths annually, due to rabies, is estimated to be between 35,000 to 50,000 approximately Rabies continues to be a major public health problem in Bangladesh killing an estimated 2000 people annually and 100,000 people receive post-exposure treatment in the country. In this regard the post-exposure treatment of animal bite cases is of prime importance. Materials and Methods: Communicable disease control(CDC) of, Directorate General of Health Services (DGHS) took the noble initiative to establish the national rabies elimination programme 2010 with an comprehensive approach of care for human and control of rabid animal.  An expert group meeting for strategic plan and finalizing the guidelines for prevention and control of rabies cases was held in 2010, under CDC of DGHS to bring out uniformity in post-exposure treatment practices. . The participants in the meeting included practitioners managing anti-rabies clinics, laboratory medicine practitioners, policy makers, public health experts from both public and private sector. The guideline, which emerged out of consensus of expert groups, is summarized in this paper. Results: Until recently the Nervous Tissue Vaccine (NTV) was the mainstay for post-exposure prophylaxis in Bangladesh. As per WHO recommendations, the production and use of this reactogenic vaccine should be gradually phased out from our country. Modern, safe and effective anti-rabies Cell Culture Vaccines (CCVs) will be used for post-exposure prophylaxis in public sectors. The limitation is the high cost of this vaccine and also the cost and unavailability of Anti Rabies Immunoglobulin. WHO recommended the use of intra-dermal (ID) route of application of CCVs. Considering the recommendations of experts, results of clinical trials and international experience, experts of Bangladesh recommends ID regimen phase wise. In first phase, only Dhaka Infectious Disease Hospital will serve as Anti-rabies centre for ID regimen. After its successful implementation, ID regimen will spread out to Division and then to District level hospitals. National experts suggested and recommended the use of cost-effective vaccination schedules such as abbreviated multisite IM Zagreb protocol (4 dose, 3 visits) and updated Thai Red Cross (TRC) intradermal regimen(2-2-2-0-2) to phase out NTV and to make available modern rabies vaccine in public sector. Conclusion: This guideline will be extremely useful for the country to make rational use of modern rabies vaccine and phase out NTV by 2011. The guideline will be of immense use for better management of animal bite cases and availability and affordability of modern rabies vaccine will be of great help for physician to manage appropriately for preventing  the deadly disease rabies.
