Results of the arterial switch operation for Taussig-Bing variants in the setting of a lower-middle income country: a single institution experience

Background: This study was conducted to evaluate the surgical results of the arterial switch operation for Taussig-Bing variants, at a single institution in a lower-middle income country. Methods: Between June 2010 and December 2018, all consecutive patients diagnosed with Taussig-Bing variants who underwent the arterial switch operation and ventricular septal defect closure were included in the study. Results: A total of 72 patients of Taussig-Bing variants who underwent arterial switch operation and ventricular septal defect closure. There were 10 early deaths (13.9%) and 2 late deaths (2.8%). Intraoperative ventricular septal defect enlargement [hazard ratio (HR) 7.23, 95% confidence interval (CI) 3.1294-16.7167; P < 0.001], secondary aortic cross clamping (HR 28.38, 95% CI 4.8427-166.3484; P < 0.001), post-operative pneumonia (HR 5.64, 95% CI 1.2724-24.9917; P = 0.023), and post-operative sepsis (HR 5.28, 95% CI 1.3512-20.6553; p = 0.017) were risk factors for overall mortality by competing risk analysis. Sixty patients (83.3%) required septoparietal trabeculation division/resection during the arterial switch operation in an attempt to avoid right ventricular outflow tract obstruction. The reoperation rate for right ventricular outflow tract obstruction at last follow up was 6% (3 patients). The estimated freedom from reoperation for right ventricular outflow tract obstruction at 1 year, 5 year and 9 year was 98.3%, 91.9% and 91.9 , respectively. Conclusions: The results of arterial switch operation for Taussig-Bing variants were satisfactory in the operative setting of a lower-middle income country, and performing extensive septoparietal trabeculation division might reduce the reintervention rate for right ventricular outflow tract obstruction in these patients.

Review on Infectious Diseases in India and their respective diagnostic platforms.

India is a lower-middle-income country with improved industrial output and expansion of innovative technologies (information, biopharmaceutical) with some notable health benefits in controlling very few infectious diseases due to an inadequate health system. It mainly focuses on providing medical care for urban population and lacks a common health framework that plays a critical role in illness prevention. However, these diseases are caused not only by a lack of sanitation and population density but also by environmental and behavioural changes. This study reviewed the literature on infectious diseases that cause deaths in India, such as tuberculosis, lower respiratory infections, and Transfusion Transmitted Infections (TTIs), diagnostic procedures for treatment and disease burden. Keywords: lower-middle-income country, Infectious diseases, Transfusion Transmitted Infections (TTIs), disease burden.

Role of Vaccine Hesitancy, eHealth Literacy, and Vaccine Literacy in Young Adults’ COVID-19 Vaccine Uptake Intention in a Lower-Middle-Income Country

Various control measures, including vaccination, have been taken to flatten the COVID-19 epidemic curve across the globe. However, in Bangladesh, many young adults, considered the asymptomatic transmitter of the disease, are waiting to get their first shot. Therefore, the potential predictors of the young adults’ vaccine uptake intention are significant to ensure their maximum vaccination when available to them. This study examined how vaccine hesitancy, eHealth literacy, and vaccine literacy are associated with young adults’ COVID-19 vaccine uptake intention in a lower-middle-income country. A total of 343 young adults participated in the study. Using ordinary least square and probit estimation, we examined the effect of the explanatory variables of interest on vaccine uptake intention. Vaccine hesitancy emerged as the strongest predictor of vaccine uptake intention. eHealth literacy shared a positive association with vaccine uptake intention, while vaccine literacy had no significant association. To make young adults feel more confident about the vaccine, transmitting the latest vaccine safety updates through authentic channels is essential. The government can aim to enhance the eHealth literacy of young adults as an increased level of eHealth literacy will enable young adults to extract reliable health-related information more efficiently than ever.
