Low bone mineral content (BMC) and bone mineral density (BMD) have been identified in human immunodeficiency virus (HIV)-infected children and adolescents. The direct adverse effects of HIV infection and combined antiretroviral therapy (ART) negatively contribute to bone metabolism. A direct relationship between muscle strength levels and BMD in HIV-infected adults and older adults has been described. However, it is unknown whether handgrip strength (HGS) is associated with bone mass in pediatric populations diagnosed with HIV. ⋯ HGS was directly associated with BMD and BMC in HIV-infected children and adolescents.

The role of transient obstructive cholestasis on liver histology remains undetermined. ⋯ Transient cholestasis was associated with significant histopathological changes, even after its resolution. Longer duration of obstruction correlated with greater severity of histopathological changes, especially cholestasis and ductular proliferation. This emphasizes the need for early treatment of obstructive cholestasis.

Critical diseases usually cause hypercortisolemia via activation of the hypothalamic-pituitary-adrenal axis. ⋯ Very high cortisol levels are associated with severe illness and increased risk of death, among COVID-19 patients in the ICU.
