Computed-tomography-based three-dimensional analysis of bilateral differences in phalanges.

Three-dimensional analysis of bones, especially for preoperative planning of corrective osteotomy in fracture malunion, assumes that the bilateral extremities exhibit a symmetrical mirror image when projected onto each other. No studies are available for phalanges. Three-dimensional bone models of all phalanges of 20 healthy participants (40 hands) were created from computed tomography data.

Neutrophil CRACR2A Promotes Neutrophil Recruitment in Sterile Inflammation and Ischemic Stroke.

Background: Ca release-activated Ca channel regulator 2A (CRACR2A) has been linked to immunodeficiency attributable to T-cell dysfunction in humans. We discovered that neutrophil CRACR2A promotes neutrophil adhesive and migratory functions by facilitating Ca mobilization and β2 integrin activation.

Methods: Myeloid-specific cracr2a conditional knockout mice and intravital microscopy were used to investigate the physiologic role of neutrophil cracr2a in neutrophil recruitment in vascular inflammation.

Hospitalized Advanced Heart Failure With Preserved vs Reduced Left Ventricular Ejection Fraction: A Global Perspective.

Background: Outcomes of hospitalized patients with heart failure (HF) and characteristics of advanced HF stage may vary across left ventricular ejection fraction (LVEF) and world regions.

Objectives: This study sought to analyze characteristics of hospitalized advanced HF patients across LVEF spectrum, world regions, and country income.

Methods: Among 18,553 hospitalized patients with acute HF (7,902 new-onset HF and 10,651 decompensated chronic HF) enrolled in the global registry REPORT-HF (International Registry to Assess Medical Practice With Longitudinal Observation for Treatment of Heart Failure), we analyzed characteristics and outcomes of patients with advanced HF, defined as previously diagnosed HF; severe symptoms before current admission (NYHA functional class III/IV); and ≥1 HF-related hospitalization in the preceding 12 months, excluding the current.

Catch the shift: Ultrasound diagnosis of scapholunate lesion during Watson test.

Scapholunate ligament lesion is the most common ligament lesion in the wrist. We assessed the reliability of sonography in detecting it during Watson test. Twenty patients with scapholunate ligament lesion confirmed on MRI and intraoperatively were assessed preoperatively between July 2020 and April 2023.

Dome versus single-cut osteotomies for correction of long bone deformities-technical considerations.

Corrective osteotomy allows to improve joint loading, pain and function. In complex deformities, the biggest challenge is to define the optimal surgical solution, while considering anatomical, technical and biomechanical factors. While the single-cut osteotomy (SCOT) and focal dome osteotomy (FDO) are well-established treatment options, their mathematical relationship remain largely unclear.
