Background: Determining a therapeutic window for maintaining antiretroviral drug concentrations within an appropriate range is required for identifying effective dosing regimens. The limits of this window are typically calculated using predictive models. We propose that target concentrations should instead be calculated based on counterfactual probabilities of relevant outcomes and describe a counterfactual framework for this.

December 2024

College of Veterinary Medicine (CVM), China Agricultural University, Beijing, China.

Lumpy skin disease virus (LSDV), a member of the capripoxvirus genus, induces lumpy skin disease (LSD) in cattle and buffalo populations. The initial documentation of LSD dates back to 1929 in Zambia, with subsequent rapid dissemination within the cattle community in Africa and Asia. Described as the "smallpox" equivalent in cattle, LSD manifests through clinical features such as fever, extensive cutaneous nodules, body wasting, lymph node enlargement, and skin edema.

Article Synopsis
  • Stunting is a major global health issue, with research indicating that boys are more affected than girls, as seen in a study of 7,486 Zambian infants where the stunting rates were 34.5% for boys compared to 25.7% for girls.
  • The study looked at various risk factors associated with stunting such as maternal characteristics and caregiving, finding few differences in exposure based on sex, although maternal marital status had some differential effects.
  • Overall, despite boys being longer than girls, both sexes showed similar patterns in growth measures, suggesting that factors influencing growth are complex and not solely dependent on sex.
