Prevalence of Carotid Artery Stenosis in Patients Undergoing Coronary Artery Bypass Grafting: A Single-Centre Study in Bangladesh.

Coronary artery disease (CAD) is one of the important causes of mortality worldwide. South Asians, notably Indians are unduly prone to develop CAD with its incidence being doubled in the last three decades among both rural and urban settlers. CAD prevalence of in Bangladesh is not known. There are merely a limited number of small-scale epidemiological studies are existing. Recent data indicates CAD prevalence in our country to lie between 1.85-3.4% in rural and 19.6% in an urban sample of working professionals. Despite marked disparity in values, the disease seems to be in rising trend. Patients with concomitant CAD and carotid artery disease are at increased risk of developing peri-operative neurological events including stroke. By far, the prevalence of carotid artery disease in candidates of CABG has not yet been determined in our country. There is a lack of pre-operative guidelines as well for the necessary vascular investigations that should be performed on CABG candidates before they go to the operation table. Pre-operative non-invasive carotid Doppler ultrasonography is a useful screening tool for carotid artery disease in all patients undergoing CABG. This was a cross-sectional observational study, was conducted in the Radiology & Imaging department of Ibrahim Cardiac Hospital & Research Institute, Dhaka, Bangladesh from January 2017 to June 2017. The present cross-sectional study was intended to determine the prevalence of concurrent occurrence of carotid and coronary artery disease in elderly patients undergoing CABG. Total 210 elderly (from 60 & above) patients scheduled for CABG taken as study population. There was bilateral carotid atherosclerotic plaque in 15(12.2%) patients. Right carotid plaque was in 69(56.0%) patients, left carotid plaque in 54(43.9%) patients. Carotid stenosis grading was done in percentage (%). There was significant (>50.0%) stenosis of right carotid system in 12 patients (17.4%) and significant stenosis of left carotid system in 18 patients (33.3%). Right carotid system & bulb was the most common site of plaque formation. We can conclude from this study that a substantial proportion of patients after a particular age possess carotid artery disease simultaneously with coronary artery disease, routine evaluation of carotid arteries of the elderly patients scheduled for CABG is strongly suggested.

Observation of Myocardial Involvement in Patients Recovered From COVID-19 by Using Cardiac Magnetic Resonance Imaging, In a Tertiary Care Hospital, Bangladesh.

It was previously reported that coronavirus caused myocardial injury in hospitalized patients. However, delayed cardiac involvement in symptomatic patient recovery from COVID-19 is not yet well known. The objective of this study was to evaluate cardiac involvement by using cardiac magnetic resonance (CMR) in symptomatic post-COVID-19 recovered patients. Thirty (30) patients who recovered from COVID-19 and had recently reported cardiac symptoms were studied in a prospective observational study performed at Popular Medical College Hospital, Dhaka, Bangladesh from March 2021 to September 2021. They underwent CMR examinations. CMR scanning protocol included the following: black blood, cine sequence, both short-axis and long-axis, T2-weight short tau inversion recovery (STIR) sequence, T2- weighted imaging (T2WI) and late gadolinium enhancement (LGE) and quantitative mapping sequences-native T1/T2 mapping and post-contrast T1 mapping. Myocardial edema and late gadolinium enhancement were assessed in all patients. Quantitative evaluation of native T1/T2 and ECV value and cardiac function were evaluated. There were 30 people in all in this study. The average age of the participants in the study was 36.6 years. Fourteen (46.6%) of the patients had abnormal cardiac MRI results, while the remaining 15(53.3%) had negative CMR findings. Among positive findings patients, 8(57.1%) of 14 had increased T2 signal. Increased myocardial edema was found in the same no of patients, involving 53.2% (128 of 224) of LV segments. Only 2 cases (2 of 14) showed mid myocardial and subepicardial LGE, involving 18 of 224, 8.03% of myocardial segments. Global native T1, T2 and ECV values are significantly elevated in all CMR positive findings patients. Native T1 1231ms (IQR: 1281.25-1257.5 versus 1155.5 (IQR: 1137.25-1172.75), T2 40 (IQR: 34.5-43.25) versus 35.5 (IQR: 34-37), ECV 31 (29.75-33.25) versus 23.5 (21.25-24.0), p<0.001; p<0.011 and p<0.001 respectively. Reduced RV functional were found in positive as compared with negative CMR findings patients, EF, 32.05 (IQR: 25.25-39.0) versus 54.5 (IQR: 52.0-57.75) and EDV, 117.5 (IQR: 102.0-134.25) versus 95.0 (IQR: 71.75-99.75), p<0.001 and p<0.001 respectively. In this study cardiac involvement was found in the post-COVID-19 recovered patient with cardiac symptoms. Cardiac MRI findings included myocardial edema, fibrosis and reduced right ventricular function. So attention should be paid to symptomatic post-COVID-19 recovered patients.

Prioritisation of teaching topics in obstetrics and gynaecology: a Delphi survey of postgraduate trainees.

Topics for theoretical teaching during the obstetrics and gynaecology specialty training programme are often chosen by tutors, with little input from the trainees. However, it is important to actively involve adults in their learning process to maintain their learning ownership and motivation. The Delphi methodology is a generic social science technique used to aggregate views and opinions of experts, the community and service users. In this study, we conducted a two generational Delphi study to achieve consensus between a group of trainees in obstetrics and gynaecology, regarding what they considered important topics for inclusion in their protected teaching programme. A total of 25 trainees from one deanery, participated in this study. We were able to produce a list of 26 topics in obstetrics and 30 in gynaecology, prioritised according to their importance for inclusion in the specialty protected teaching programme, as viewed by these trainees.

Using village theatre to increase knowledge about eclampsia in Bangladesh.

OBJECTIVE: To assess the impact of a theatre based educational initiative on the knowledge and attitudes to eclampsia and its treatment in a rural Bangladeshi village. METHODS: An established theatre company, Theatre Centre for Social Development, performed scenarios regarding eclamptic pregnant women to a diverse audience of village observers. Before the performance 15 men and 15 women were randomly selected from the audience and asked a series of questions regarding eclampsia. After the performance the series of questions were repeated to the same people. RESULTS: The plays were enthusiastically received by the villagers. The level of knowledge of the villagers interviewed increased significantly after seeing the two plays. CONCLUSION: The intervention successfully raised both the awareness of eclampsia and the level of knowledge of effective treatments for eclampsia. Village theatre has shown the potential to be a very effective tool in Bangladeshi rural society.
