Perspectives of Canadian Plastic Surgeons on the Surgical Management of Pressure Injuries.

Pressure injuries, particularly among patients with spinal cord injuries and the elderly, significantly contribute to morbidity, mortality, and financial sequelae. Surgical interventions, including debridement and flaps, may improve outcomes, especially for stage 3 and 4 pressure injuries. This survey assesses Canadian plastic surgeons' perspectives and practices regarding the surgical management of these injuries.

Automation for lateral flow rapid tests: Protocol for an open-source fluid handler and applications to dengue and African swine fever tests.

Lateral flow rapid diagnostic tests (RDTs, RTs) are cost-effective with low infrastructure requirements for limited-resource settings, and in any setting can represent a bridge between early disease monitoring at outbreak onset and fully-scaled molecular testing for human or animal diseases. However, the potential of RTs to handle higher throughput testing is hampered by the need for manual processing. Here we review dengue virus and African swine fever virus rapid tests, and present a novel protocol that employs an open-source fluid handler to automate the execution of up to 42 RTs per run.

Nested admixture during and after the Trans-Atlantic Slave Trade on the island of São Tomé.

Human admixture history is rarely a simple process in which distinct populations, previously isolated for a long time, come into contact once to form an admixed population. In this study, we aim to reconstruct the complex admixture histories of the population of São Tomé, an island in the Gulf of Guinea that was the site of the first slave-based plantation economy, and experienced successive waves of forced and deliberate migration from Africa. We examined 2.
