The range sizes of sediment-dwelling deep-sea species are largely unknown. Such knowledge is important because a deep sea composed in large part of species with 100-km-scale ranges would be very different from one composed predominantly of species with 1000-km-scale ranges. For example, the total species richness would be much greater in the first case than in the second. As a step towards the determination of the distribution of species' range sizes in the deep sea, we asked whether harpacticoid copepods (Crustacea) on the continental rise in the northeastern Pacific had 1000-km-scale range sizes. We chose harpacticoids because they occur widely in deep-sea sediments and thus are a typical deep-sea taxon. In addition, they have no pelagic stage in their life history, so they allow a conservative test of hypotheses about species' range sizes. We used morphology and gene-sequence data to assign individuals to species. At least 13.3% of the species we studied had 1000-km-scale ranges, raising the question of how these species maintain genetic continuity.

Current Role of Pneumatic Compression Therapy in Lymphedema Care: A Scoping Review of Persistent Debates and New Applications.
Lymphology

Vascular Medicine Unit, Cholet Hospital, Cholet, France.
Access to trained lymphedema care providers remains limited making patient-driven management solutions essential. One such option, sequential intermittent pneumatic compression (IPC), has gained traction as a supportive tool for lymphedema management. While newer IPC devices and innovative applications are being introduced to the market, questions regarding the safety and efficacy of this technology persist.

Objectives: Pathways Community Hub (PCH) programs help connect pregnant women to healthcare and social services. A scoping review of peer-reviewed studies on PCHs that reported quantitative outcomes was conducted.
Methods: A search of academic databases from 1901 to 2024 initially yielded a total of 1,312 articles, which was ultimately reduced to 4 articles after duplicates were removed, and two levels of screening were conducted to determine whether studies met the inclusion criteria of evaluating a community hub for pregnant women, was written in English, was peer-reviewed, and reported quantitative outcomes.

Evidence suggests that sodium nitrite may be effective in the treatment of hypertension and pulmonary hypertension. However, its use remains debated due to safety concerns. In response, a scoping review was conducted to map current knowledge on the efficacy and safety of sodium nitrite in patients with hypertension or pulmonary hypertension, addressing the question: What evidence supports the effectiveness and safety of using sodium nitrite in these patients? The databases MEDLINE (PubMed), EMBASE, Scopus, Web of Science, and LILACS were searched for clinical studies on hypertensive patients at any disease stage without restrictions on age, sex, ethnicity, publication date, or status.

Recovery support services as part of the continuum of care for alcohol or drug use disorders.

Background: The definition of 'recovery' has evolved beyond merely control of problem substance use to include other aspects of health and wellbeing (known as 'recovery capital') which are important to prevent relapse to problematic alcohol or other drug (AOD) use. Developing a Recovery Oriented System of Care (ROSC) requires consideration of interventions or services (Recovery Support Services, RSS) designed to build recovery capital which are often delivered alongside established treatment structures. Lived experience and its application to the process of engaging people, changing behaviour and relapse prevention is an essential part of these services.
