Facultative scavenging can be observed across a large range of carnivorous mammals but is an uncommon behavioural trait in cheetahs (). Very few incidents of cheetahs scavenging have been reported, with no explanation given as to why it may occur. In this paper, we provide three more observations of cheetahs scavenging between 2019 and 2023 in three different protected areas in South Africa and Malawi.

Objectives:  Traditionally, midline vertical skin incisions have been utilized during surgery for placenta accreta spectrum (PAS), as it is considered to maximize exposure and allow for a uterine incision to avoid the placenta. However, literature directly comparing outcomes of vertical versus transverse incisions in PAS is sparse. Our objective was to compare maternal outcomes between patients who underwent a vertical versus a transverse skin incision for PAS.

Article Synopsis
  • A study on the effects of statin therapy in people living with HIV (PWH) found that while it did not reduce the overall incidence of COVID-19, it may lower the risk of severe cases of COVID-19 before vaccination.
  • The study analyzed data from 6,905 PWH and included variables such as age, gender, and race, showing that a majority had received COVID-19 vaccinations by the end of the study period.
  • Statin therapy demonstrated a potential protective effect against serious COVID-19 cases, as evidenced by a hazard ratio of 0.75, but the results were inconclusive due to fewer cases than expected.
