ObjectiveThis study aimed to explore the knowledge, attitude and behaviour regarding male infertility among medical students and healthcare workers in Bangladesh.DesignThis was a cross-sectional study.SettingThis study covered eight divisions of Bangladesh.ParticipantsThe participants were medical students or healthcare professionals of Bangladesh who were surveyed anonymously on their knowledge, attitude and perception regarding male infertility.Primary outcome measuresThe level of knowledge, attitude and perception regarding male infertility.AnalysisThe mean knowledge and attitude scores were then correlated with sociodemographic factors using χ2and two-independent sample t-tests. Finally, we performed binary logistic regression to explore predictors of good knowledge and positive attitude.ResultAmong 556 participants, 49.82% did not have good male infertility knowledge, and nearly 60.79% had negative attitudes regarding male infertility. Young (23–26 years) healthcare professionals and medical students were more likely to have good knowledge than others (OR: 1.81; 95% CI 1.099 to 2.988). Surprisingly, women were more likely to have a positive attitude (OR=1.48; 95% CI 1.002 to 2.19, p=0.049) than men. Among all the professions, Bachelor of Medicine and Surgery doctors were most likely to have good knowledge and a positive attitude regarding male infertility. Good knowledge of male infertility predicted a positive attitude (OR=1.61; 95% CI 1.105 to 2.346, p=0.013) and vice versa.ConclusionOur research found that healthcare professionals and medical students in Bangladesh had inadequate knowledge and negative attitudes regarding male infertility despite favourable opinions. This emphasises the need for interdisciplinary training programmes, standardisation of healthcare worker guidelines and curricular adjustments for medical students.

Background Bangladesh’s population commonly utilizes Complementary and alternative medicine (CAM) to treat their health issues. Despite the increasing interest in CAM, it has been excluded from conventional medical training in Bangladesh for many years. Therefore, this study assessed and compared the knowledge level, attitude, perceived effectiveness, and self-practice of CAM among undergraduate students of Bangladesh. Methods This cross-sectional group comparison study was conducted among undergraduate (both medical and non-medical) students of Bangladesh between November and December 2021. Data was collected using a self-reported pretested semi-structured online questionnaire. The questionnaire contained questions regarding background information, knowledge regarding CAM, source of CAM knowledge, attitude towards CAM, interest in attaining CAM knowledge, perceived effectiveness of CAM, perceived adverse effects of CAM, self-practice of CAM, and whether would they refer CAM to others. A total of 576 students responded and the data gathered allowed for the following: (1) an overview of the study groups, (2) respondents’ general perception and knowledge regarding CAM, and (3) a comparison of respondents’ CAM knowledge, general perception, and usage by area of study. Data were analyzed using STATA (v.16) and descriptive statistics, Pearson’s chi-square test, and Mann-Whitney U test were performed. Results A total of 329 medical students and 247 non-medical students participated in the study. The mean age of the participants was 21.57 ± 1.8 years and 56.2% of them were male. The most known CAM among medical (M) students was homeopathy (44.6%) and among non-medical (NM) students were herbal medicine (45.7%). Non-medical students had significantly better knowledge about nine out of twelve CAM modalities included in the study, and no significant differences were present for the rest of the modalities. Medical (81.1%) and non-medical students (86.2%) perceived traditional Chinese medicine and homeopathy to be the most effective respectively. “Incorporating CAM with conventional medicine would result in increased patient satisfaction” showed the most statistically significant (p = 0.0002) difference among both groups. Yoga was the most often practiced modality among medical students and homeopathy among non-medical students. Conclusion Medical students have a lacking of knowledge and a positive attitude towards CAM, despite its very common practice among the people of Bangladesh. Therefore, emphasis should be put on the inclusion of CAM modules in medical training.

Background When caring for COVID-19 patients, using personal protective equipment (PPE) may significantly lower the risk of infection of health care workers (HCWs). However, adverse responses due to PPE use have been observed during the 2003 SARS pandemic. This study will highlight the different adverse reactions caused by face mask use, one of the essential components of PPE in the HCWs, and identify the factors associated with these problems. Methods This cross-sectional survey was conducted between September and October 2021. 404 HCWs were selected by snowball sampling from four randomly selected healthcare facilities of Bangladesh. Trained volunteers collected data by face-to-face interview using a pretested structured questionnaire. Data were analyzed using STATA (v.16) and summarized using frequency and relative frequency. Later, the chi-square test was used to explore bivariate relationships, and the binary logistic regression model was fit to identify the predictors. Results The majority of the respondents were 26–36 years (70.30%), male (69.80%), and doctors (74.50%). 48.76% of the respondents had unfavorable skin responses beneath the face masks; female gender, physicians, professionals working more than 32 hours a week, wearing N95, and more than one mask were predictors of skin problem. 28.47% and 60.15% of all participants suffered from some form of oral and neurological problems, respectively. Conclusion Face mask use sequelae, especially skin, oral and neurological problems, are prevalent among health care workers. Therefore, necessary precautionary measures should be taken to safeguard our frontlines.

BackgroundPatients with severe atherosclerosis have been found to exhibit considerable changes in blood pressure (BP) between arms. The objective of our study was to investigate the predictive value of interarm blood pressure difference (IABPD) for coronary artery disease (CAD) severity.MethodsIt was a cross-sectional study conducted in the Department of Cardiology, Chittagong Medical College Hospital, Chattogram from May 2020 to November 2020. The study conveniently selected 110 individuals who visited the department for a coronary angiography during the study period. The BP of both arms were synchronously measured 1–2 days before the coronary angiography and IABPD were calculated. After coronary angiography, two blinded interventional cardiologists visually estimated the amount of coronary artery obstruction and determined the Gensini score.ResultsAmong the participants, more than three-fourths of the patients were above 50 years of age (64.66%), and the majority were male (86.67%). 14.7% of participants had no occlusion in their coronary artery, 38.0% of participants had insignificant occlusion, 26.7% participants had mild occlusion, 10.3% participants had moderate occlusion, 3.3% participants had significant occlusion and 6.0% participants had total occlusion. Corrected pulse IABPD (cIABPDpulse) showed the greatest area under the receiver operating characteristic curve (0.73) for predicting a high Gensini score (>median). Multiple regression analysis revealed a significant relationship between corrected systolic IABPD (cIABPDsys) and the Gensini score (B=0.057, pConclusionThe differences in BP between the arms were found to be having a strong positive correlation with CAD severity.

Following the worldwide COVID-19 pandemic, individuals have begun to take preventive measures to avoid exposure. Among the precautionary measures, facemask was mostly emphasized. This study aimed to determine the prevalence of dermatological symptoms linked with face mask usage and explore other associated factors. This cross-sectional survey was conducted throughout all eight divisions of Bangladesh. 1297 people were approached using a fixed-step procedure on a random route sample where 803 fulfilled the inclusion criteria. The overall prevalence of dermatological manifestation in this study was 40.85%. The common dermatological manifestations due to facemasks use were acne (26%), allergy symptoms (24%), traumatic symptoms (24%), and other symptoms (26%). Two important frequently reported risk factors were previous history of skin diseases and obesity. Females were more likely to have acne (CI: 1.199, 3.098; p = .007) and allergy issues (CI: 1.042, 2.359; p = .031). N95 and KN95 masks were more likely to produce allergic symptoms, while surgical mask users were more likely to develop acne. Acne was prevalent more than twice (CI: 1.42, 4.26; p = 0.001) in persons with a COVID-19 infection history. Further exploration is required to find out the reason. Surgical mask users reported more complaints than other types of masks, and prolonged use caused more skin symptoms. Modifications in the pattern of facemask usage and planning for work recesses might also be advised to provide for a pause from uninterrupted facemask use.
