BACKGROUND Acute respiratory distress syndrome (ARDS) due to coronavirus 2019 (COVID-19) can result in severe disease requiring mechanical ventilatory support. A subset of these patients, however, demonstrate refractory hypoxemia/hypercarbia requiring veno-venous extracorporeal membrane oxygenation (V-V ECMO) as adjunctive therapy. The primary goal of V-V ECMO is a "bridge" to recovery of native lung function; however, patients may progress to irreversible pulmonary damage requiring lung transplantation.

The Moche archaeological culture flourished along Peru's North Coast between the 4th and 10th centuries CE and was characterized by a complex social hierarchy dominated by political and religious elites. Previous archaeological evidence suggests kinship was a key factor in maintaining political authority within Moche society. To test this hypothesis, we applied archaeological, genetic, and isotopic methods to examine familial relationships between six individuals, including the prominent Señora de Cao (), buried together in a pyramid-like, painted temple, Huaca Cao Viejo, in the Chicama Valley, Peru.

Introduction: The adoption of colorectal endoscopic submucosal dissection (ESD) is still limited in the West. A recent randomized trial showed that ESD is more effective and only slightly riskier than piecemeal endoscopic mucosal resection; reproducibility outside expert centers was questioned. We evaluated the results according to the annual case volume in a multicentric prospective cohort.

Negative associations of health disorders with reproductive performance, often measured with pregnancy per AI or the risk of pregnancy loss, have been demonstrated extensively. Most studies investigated common clinical diseases but did not include subclinical disorders comprehensively. They often evaluated cows subjected to hormonal synchronization protocols for timed AI, limiting the ability to understand how disease may affect spontaneous reproductive function, which is essential for targeted management programs with selective hormonal intervention.

Research that involves agricultural animal welfare has typically aimed to improve welfare by decreasing disease, distress, and pain. Positive welfare does not necessarily occur with the absence of suffering but in combination with opportunities for behaviors or affective states desired by animals. Our objectives were to describe Canadian bovine veterinarians' and veterinary students' attitudes, professional normative values, and perceived ability to promote positive welfare for dairy cows, and to explore participants' provided rationale.
