Secondary contact erodes Pleistocene diversification in a wide-ranging freshwater mussel (Quadrula).

The isolated river drainages of eastern North America serve as a natural laboratory to investigate the roles of allopatry and secondary contact in the evolutionary trajectories of recently diverged lineages. Drainage divides facilitate allopatric speciation, but due to their sensitivity to climatic and geomorphological changes, neighboring rivers frequently coalesce, creating recurrent opportunities of isolation and contact throughout the history of aquatic lineages. The freshwater mussel Quadrula quadrula is widely distributed across isolated rivers of eastern North America and possesses high phenotypic and molecular variation across its range.

Implementing Evidence-Based Pain Management Interventions Into an Emergency Department: Outcomes Guided by Use of the Ottawa Model of Research Use.

Aim: To implement strategies to improve the care of patients with acute pain in the emergency department (ED).

Design: Pre-post implementation study using a Type 2 hybrid effectiveness-implementation design.

Methods: Implementation strategies were introduced and monitored through the Ottawa Model of Research Uses' assessment, monitoring and evaluation cycles, supported by focused and sustained facilitation.

The impact of age and renal function on the pharmacokinetics and protein binding characteristics of fludarabine in paediatric and adult patients undergoing allogeneic haematopoietic stem cell transplantation conditioning.

Aim: To evaluate the population pharmacokinetics of unbound F-Ara-A (the circulating metabolite of fludarabine) in 211 patients (age range, 0.1-63.4 years) undergoing allogeneic haematopoietic stem cell transplantation conditioning.

Low-Level BCR::ABL1 Transcript at Diagnosis in Childhood Leukemia: A 10-Year Single Institution Study.

Introduction: Philadelphia chromosome-positive (Ph+) acute lymphoblastic leukemia (ALL) is a high risk form of ALL associated with dismal outcomes in the pre-tyrosine kinase inhibitor (TKI) era. Addition of a TKI to chemotherapy improves outcomes. Therefore, testing for the presence of the Philadelphia chromosome by at least two methods at the time of diagnosis is critical.
