Direct factor Xa inhibitors versus low molecular weight heparins or vitamin K antagonists for prevention of venous thromboembolism in elective primary hip or knee replacement or hip fracture repair.

Background: People undergoing major orthopaedic surgery are at increased risk of postoperative thromboembolic events. Low molecular weight heparins (LMWHs) are recommended for thromboprophylaxis in this population. New oral anticoagulants, including direct factor Xa inhibitors, are recommended as alternatives.

and Fungi Improve Performance of Plants Grown in Sandy Substrate with Added Sewage Sludge.

The use of living organisms to treat human by-products, such as residual sludge, has gained interest in the last years. Fungi have been used for bioremediation and improving plant performance in contaminated soils. We investigated the impact of the mycorrhizal fungus (MF) and the saprophytic fungus (SF) on the survival and growth of seedlings cultivated in a sandy substrate supplemented with residual sludge.

Research Attitudes Questionnaire scores and retention in a recruitment registry.

Background: Recruitment registries are maximally effective when registrants are retained to the point of referral. The Research Attitudes Questionnaire (RAQ) has previously been shown to predict research participation behaviors, including Alzheimer's disease clinical trial completion.

Objective: To test the hypothesis that RAQ score is associated with retention behaviors in a local recruitment registry.

Changes in Emergency Department Practices After Implementation of a Standardized Heavy Menstrual Bleeding Guideline.

Objective: The aim of the study is to assess the effect of an emergency department (ED) standardized clinical guideline for adolescent heavy menstrual bleeding on the rate of return ED visits and ED provider history-taking and management of this condition.

Methods: This was a retrospective cohort study. Patients less than 18 years old presenting to a single academic children's hospital ED between 2010 and 2020 with a chief complaint of heavy menstrual bleeding were included.

Programming the elongation of mammalian cell aggregates with synthetic gene circuits.

A key goal of synthetic morphogenesis is the identification and implementation of methods to control morphogenesis. One line of research is the use of synthetic genetic circuits guiding the self-organization of cell ensembles. This approach has led to several recent successes, including control of cellular rearrangements in 3D via control of cell-cell adhesion by user-designed artificial genetic circuits.
