The cheetah the fastest living land mammal, is an atypical member of the family Felidae. The extinct feline known as the North American cheetah, is thought to have convergently evolved with to pursue fast and open-country prey across prairies and steppe environments of the North American Pleistocene. The brain of is unique among the living felids, but it is unknown whether the brain of the extinct is convergent to that of . Here, we investigate the brain of from a cranium endocast, using a comparative sample of other big cats. We demonstrate that the brain of was different from that of the living . Indeed, its brain shows a unique combination of traits among living cats. This suggests that the case of extreme convergence between and its living Old World vicar should be reconsidered.

Despite efforts to address inequities, research on women's health conditions (defined as those that uniquely or differently affect women and female individuals) remain significantly understudied. As directed by Congress, the National Institutes of Health (NIH) Office of Research on Women's Health requested the National Academies of Sciences, Engineering, and Medicine (National Academies) to conduct an assessment of the state of women's health research at the NIH. The findings of the National Academies committee include: 1) a significant funding inequity, with less than 8% of the total NIH grant budget for fiscal year 2023 allocated to women's health research; 2) a need for improved strategic NIH-wide priority setting, oversight, and adherence to existing policies to support women's health research; 3) a need for a specific institute for research on conditions specific to women's health; and 4) a need for sufficient training and additional funding to grow and retain the women's health research workforce.

Case: We report a case of a 29-year-old woman who sustained a left lateral sternoclavicular joint (SCJ) dislocation. Imaging demonstrated a 30-mm gap between the sternum and medial clavicle. Given well-preserved shoulder range of motion and well-controlled pain, she was ultimately treated nonoperatively.

Despite having an overall lower lifetime risk for skin cancer, Latine/Hispanic individuals experience increased morbidity and mortality in skin cancer outcomes compared to non-Hispanic White individuals. The reasons for these disparate outcomes are multifactorial, but challenges in early skin cancer detection, limited awareness of risks, and inequitable access to care and/or treatment among this patient population likely are contributory. In this article, we review cutaneous malignancies in the Latine/Hispanic population and explore factors that impact overall prognosis, including unique clinical features, inadequate health coverage, medical mistrust, language barriers, differing cultural perspectives, and inadequate research.

Importance: Reducing the burden of stroke is a public health priority. While higher stroke incidence among ethnic minority populations (defined in the context of this study as individuals who are not White) is well established, reports on ethnic inequalities in care or outcomes are conflicting and often limited to hospital-admitted patients and short-term outcomes.
Objective: To investigate ethnic differences in stroke care and outcomes up to 5 years after stroke and describe temporal trends and contributory factors.
