Intraoperative physician assessment during total hip arthroplasty correlates with DXA parameters.

Purpose: Orthopedic surgeons can assess bone status intraoperatively and recommend skeletal health evaluation for patients with poor bone quality. Intraoperative physician assessment (IPA) at the time of total knee arthroplasty correlates with preoperative DXA-measured bone mineral density (BMD). This study evaluated IPA during total hip arthroplasty (THA) as a quantitative measure of bone status based on tactile assessment.

Hemiarthroplasty for Femoral Neck Fractures: Does Surgeon Subspecialty Affect Perioperative Outcomes?

Objectives: To determine if surgeon subspecialty training affects perioperative outcomes for displaced femoral neck fractures treated with hemiarthroplasty.

Design: Retrospective comparative study.

Setting: One health system with 2 hospitals (Level I and Level III trauma centers).

Progress and challenges in coupled hydrodynamic-ecological estuarine modeling.

Numerical modeling has emerged over the last several decades as a widely accepted tool for investigations in environmental sciences. In estuarine research, hydrodynamic and ecological models have moved along parallel tracks with regard to complexity, refinement, computational power, and incorporation of uncertainty. Coupled hydrodynamic-ecological models have been used to assess ecosystem processes and interactions, simulate future scenarios, and evaluate remedial actions in response to eutrophication, habitat loss, and freshwater diversion.

Gene expression changes in the MAPK pathway in both Fragile X and Down syndrome human neural progenitor cells.

The two most common genetic developmental disorders that cause intellectual disability are Down syndrome (DS) and Fragile X syndrome (FXS). Although the genetics and behavioral hallmarks of these two disorders are distinct, common underlying defects in neural development may lead to the cognitive impairment characteristic of both. Human neural progenitor cells (hNPCs) enable the study of prenatal human brain development in these developmental disorders.
