Shared Decision-Making in Total Hip and Knee Arthroplasty: Understanding Surgeon and Patient Perspectives Regarding When It Is Time for Surgery.

Background: Although total hip and total knee arthroplasty are highly successful operations, the decision of whether and when to undergo surgery is highly subjective and discretionary, and specific guidelines regarding readiness for surgery remain elusive. The nature of these decisions underscores the importance of shared decision-making, which is founded on the concept that patients substantially contribute to determining their own readiness for surgery. The OPTION survey was developed as a conversation aid to facilitate shared decision-making in the context of total joint arthroplasty.

Summer primary production of Arctic kelp communities is more affected by duration than magnitude of simulated marine heatwaves.

Fjord systems in the Norwegian Arctic are experiencing an increasing frequency and magnitude of marine heatwaves. These episodic heat stress events can have varying degrees of acute impacts on primary production and nutrient uptake of mixed kelp communities, as well as modifying the biogeochemical cycling in nearshore systems where vast areas of kelp create structural habitat. To assess the impact of future marine heatwaves on kelp communities, we conducted a 23 day mesocosm experiment exposing mixed kelp communities to warming and heatwave scenarios projected for the year 2100.

Acute colonic pseudo-obstruction in polytrauma patients.

Background: Acute colonic pseudo-obstruction (ACPO) is characterized by severe colonic distension without mechanical obstruction. It has an uncertain pathogenesis and poses diagnostic challenges. This study aimed to explore risk factors and clinical outcomes of ACPO in polytrauma patients and contribute information to the limited literature on this condition.

Productivity of mixed kelp communities in an Arctic fjord exhibit tolerance to a future climate.

Arctic fjords are considered to be one of the ecosystems changing most rapidly in response to climate change. In the Svalbard archipelago, fjords are experiencing a shift in environmental conditions due to the Atlantification of Arctic waters and the retreat of sea-terminating glaciers. These environmental changes are predicted to facilitate expansion of large, brown macroalgae, into new ice-free regions.
