Publication Early Canities among Undergraduate Medical Students of a Medical College: A Descriptive Cross-sectional Study(Nepal Medical Association, 2023) Chaudhary, Sonam; Mahotra, Narayan BahadurAbstract Introduction: Early canities are the premature greying of hair before the age of 25 years in Asians. The condition is a matter of concern for young adults aesthetically. This study aimed to find out the prevalence of early canities among undergraduate medical students of a medical college. Methods: A descriptive cross-sectional study was carried out from 1 December 2021 to 30 June 2022 among undergraduate medical students at a medical college. The study was conducted after receiving ethical approval from the Institutional Review Committee [Reference number: 146(6-11)C-2 078/079]. The participants with ages less than 25 years without a history of vitiligo, intake of chemotherapeutic drugs, progeria, pangeria and recent dyeing of hair were enrolled. A convenience sampling method was used. Point estimate and 95% Confidence Interval were calculated. Results: Out of 235 students, 95 (40.42%) (34.15-46.69, 95% Confidence Interval) had early canities. The most prevalent premature greying was grade I early canities i.e.79 (83.15%) of participants. Among the participants with early canities, 56 (58.94%) were male, 41 (43.15%) had a positive family history for early canities, 67 (70.52%) had normal body mass index and 38 (40%) had O+ve blood group. Conclusions: The prevalence of early canities among undergraduate medical students was lower than in other studies done in similar settings. The grade I early canities was seen more among the participants with premature greying of hair.Publication Pattern of Blood Products Consumption in a Teaching Hospital(Nepal Health Research Council, 2024) Shrestha, Lava; Gurung, Numaya; Mahotra, Narayan Bahadur; Pradhan, Sait; Ghimire, Ananda; Pokhrel, Kailash Mani; Khanal, Kapil; Dhungana, Reechashree; Gautam, Naveen; Kandel, Sabita; Chaudhary, SonamBackground: Blood transfusions are lifesaving, but resource limitations and inadequate utilization patterns pose challenges in low- and middle-income countries. In Nepal, detailed analyses of blood use practices, are needed to inform resource allocation and policy decisions. The objective of this study was to study the overall and component-specific use, explore temporal trends in utilization of blood and blood products. Methods: We conducted an observational study analyzing data from Blood Bank of Tribhuvan University Teaching Hospital (TUTH), a tertiary hospital (January 1st - December 31st, 2019). Data included patient demographics, blood groups, blood products requested and transfused, and facility type. Data analysis was conducted with SPSS v20. Results: Patients from TUTH had substantially higher blood product requests, requesting 25,716 units compared to only 1855 units across other centers combined. Blood groups A positive (8089, 31.4%) and and O positive (7851, 30.6%) were the most requested blood groups. Whole blood (11358, 44.2%) and packed red blood cells (9565, 37.2%) were most frequently requested. We observed monthly fluctuations in demand with peak of 2742 requests in December with a trough in June (1947 units). Notably, only approximately 46% of blood products requested from patients admitted to TUTH were ultimately transfused. Conclusions: Whole blood and packed red blood cells were the most frequently requested blood products. Eventhough whole blood was the most frequently requested blood product, the most transfused one was packed red cells. Peak demand was observed in December. Our study provides valuable insights into blood utilization patterns, underscoring the need for specific strategies to improve blood transfusion management practices.
