November 2025 in “American Journal of Tropical Medicine and Hygiene” In this study, researchers observed that approximately 1.15% of dengue fever patients experienced alopecia, predominantly among females. The hair loss usually occurred during the recovery phase and was often identified as telogen effluvium, with lower platelet count and hematocrit levels potentially serving as risk factors.
This retrospective cohort study found that lower postoperative nadir hematocrit levels were significantly associated with higher 28-day mortality and worse secondary outcomes after coronary artery bypass grafting, with an optimal survival benefit observed when nadir hematocrit ranged from 27% to 31%.
