BackgroundIn Bangladesh, pneumonia has a higher mortality among malnourished children aged <5 years. Evaluating pneumonia etiology among malnourished children may help improve empiric treatment guidelines.

Background: Hypertension (HTN) is well established as a leading cause of common serious illnesses worldwide. We carried out this qualitative research to understand perception of and experiences related to HTN among rural Bangladeshi hypertensive women. Methods: A total of 74 female hypertensive participants who were diagnosed as HTN were purposively recruited in a rural community in Mirzapur, Bangladesh. A focus group discussion(FGD) was applied to share their perception and experiences. Transcripts were read in an iterative process, and a thematic analysis was performed. This paper is reported followed by COREQ checklist. Results: Three main themes were generated; (i) Perception of HTN based on experiences, (ii)Knowledge of management of HTN, and (iii) Barriers of management of HTN. Under the themes, seven subthemes were identified. The participants only knew about their high blood pressure(HBP) when they had symptoms, and they applied traditional remedies in the rural context to deal with those symptoms. Even though more than half of participants had relevant knowledge of how to manage HTN, but still there were social-cultural and economic barriers and lack of social infrastructure to access healthcare, existed to practice them. Conclusion: Based on our study reports, health education programs at the household and community level could be a potential starting point for any preventive and containment strategy in rural communities of Bangladesh.

Background An improved understanding of childhood pneumonia aetiology is required to inform prevention and treatment strategies. Lung aspiration is the gold standard specimen for pneumonia diagnostics. We report findings from analyses of lung and pleural aspirates collected in the Pneumonia Etiology Research for Child Health (PERCH) study. Methods The PERCH study enrolled children aged 1–59 months hospitalized with World Health Organization defined severe or very severe pneumonia in 7 countries in Africa and Asia. Percutaneous trans-thoracic lung (LA) and pleural fluid (PF) aspiration was performed on a sample of pneumonia cases with radiological consolidation and/or pleural fluid in 4 countries. Venous blood and nasopharyngeal/oropharyngeal swabs were collected from all cases. Multiplex quantitative PCR and routine microbiologic culture were applied to clinical specimens. Results Of 44 LAs performed within 3 days of admission on 622 eligible cases, 13 (30%) had a pathogen identified by either culture (5/44) or by PCR (11/29). A pathogen was identified in 12/14 (86%) PF specimens tested by either culture (9/14) or PCR (9/11). Bacterial pathogens were identified more frequently than viruses. All but one of the cases with a virus identified were co-infected with bacterial pathogens. Streptococcus pneumoniae (9/44 [20%]) and Staphylococcus aureus (7/14 [50%]) were the predominant pathogen identified in LA and PF, respectively. Conclusions Bacterial pathogens predominated in this selected subgroup of PERCH participants drawn from those with radiological consolidation or pleural fluid, with S. pneumoniae and S. aureus the leading pathogens identified.

The efficacy of commonly used antibiotics for treating severe cholera has been compromised over time because of the reduced antibiotic susceptibility. This study aimed to describe the rate of detection of Vibrio cholerae O1 from fecal samples and antimicrobial susceptibility profiles of V. cholerae O1 serotypes to commonly used antibiotics.
