An interdisciplinary approach to improving conservation outcomes for parasites.

Parasites represent a significant proportion of Earth's biodiversity and play important roles in the ecology and biology of ecosystems and hosts, making them an important target for conservation. Despite increasing calls to prioritize protection for parasites in the academic literature, they remain undervalued and underrepresented in global biodiversity conservation efforts, not least due to the perception that the interests of parasite and host conservation are opposing and the common misconception that parasites are a threat, rather than a benefit, to conservation. We considered whether taking an interdisciplinary approach to parasite conservation research will generate novel insights and solutions concerning why and how parasite conservation should be practiced for the benefit of parasites, their hosts, ecosystems, and people.

Survivorship and Outcomes of Hip Arthroplasty for Elective Care Versus Fracture in Patients Who Have Solid Organ Transplant: Lung Transplant Patients Do Worse.

Background: With continued improvement in patient outcomes following solid organ transplant (SOT), more SOT recipients may benefit from hip arthroplasty. This study sought to compare the perioperative complications and survivorship of SOT recipients undergoing hip arthroplasty for elective care versus for fracture.

Methods: A single-institution retrospective review yielded 95 hip arthroplasty procedures (80 patients) performed between August 2016 and May 2023 with a mean follow-up of 35 months.

Persistent pollutant exposure impacts metabolomic profiles in polar bears and ringed seals from the High Arctic and Hudson Bay, Canada.

Metabolomics measures low molecular weight endogenous metabolites and changes linked to contaminant exposure in biota. Few studies have explored the relationship between metabolomics and contaminants in Arctic wildlife. We analyzed 239 endogenous metabolites and ∼150 persistent organic pollutants (POPs), including total mercury (THg), in the liver of polar bears and their ringed seal prey harvested from low Canadian Arctic (western Hudson Bay; WHB) and high Arctic (HA) locations during 2015-2016.

Core Components of Cardiac Rehabilitation Programs: 2024 Update: A Scientific Statement From the American Heart Association and the American Association of Cardiovascular and Pulmonary Rehabilitation: Endorsed by the American College of Cardiology.

The science of cardiac rehabilitation and the secondary prevention of cardiovascular disease has progressed substantially since the most recent American Heart Association and American Association of Cardiovascular and Pulmonary Rehabilitation update on the core components of cardiac rehabilitation and secondary prevention programs was published in 2007. In addition, the advent of new care models, including virtual and remote delivery of cardiac rehabilitation services, has expanded the ways that cardiac rehabilitation programs can reach patients. In this scientific statement, we update the scientific basis of the core components of patient assessment, nutritional counseling, weight management and body composition, cardiovascular disease and risk factor management, psychosocial management, aerobic exercise training, strength training, and physical activity counseling.

Enhancing single-cell transcriptomics using interposed anchor oligonucleotide sequences.

Single-cell transcriptomics, which utilises barcodes and unique molecular identifiers (UMIs) for polyA+ mRNA capture, is compromised by oligonucleotide synthesis errors. To address this, we modified the oligonucleotide capture design and integrated an interposed anchor between the barcode and the UMI. This design significantly reduces the need to discard reads due to synthesis inaccuracies.
