Regression tools for chemical release modeling: An additive manufacturing case study.

Chemical release data are essential for performing chemical risk assessments to understand the potential exposures arising from industrial processes. Often, these data are unknown or unavailable and must be estimated. A case study of volatile organic compound releases during extrusion-based additive manufacturing is used here to explore the viability of various regression methods for predicting chemical releases to inform chemical assessments.

Prehospital Trauma Compendium: Vasopressors in Trauma - a Position Statement and Resource Document of NAEMSP.

Acutely injured trauma patients may develop shock from several potential mechanisms, including hypovolemic shock from hemorrhage, neurogenic shock from traumatic brain injury (TBI) or spinal cord injury, obstructive shock from tension pneumothorax or pericardial tamponade, or a mix of several of these mechanisms. Regardless of the cause, restoration of adequate perfusion is of critical importance to reduce the morbidity and mortality of trauma patients with shock. Multiple interventions including hemorrhage control, volume resuscitation with intravenous fluids or blood products, and pleural decompression procedures are used to address some of these issues and are discussed elsewhere in the trauma compendium.

Advanced Multi-Layer Watertight Closure versus Conventional Closure in Total Hip and Knee Replacement Surgery.

Background: In total joint replacement procedures, surgeons have increasingly adopted advanced multi-layer, watertight closure. The objective of the study was to compare the clinical and economic outcomes for advanced multi-layer, watertight closure patients to those with conventional closure with sutures and skin staples.

Methods: Patients aged ≥18 years were included in the study if they underwent total joint arthroplasty of the hip or knee as an elective, primary, inpatient procedure between January 2014 and March 2019.

Systematic Reporting of Eosinophils in Transbronchial Biopsies After Lung Transplantation Defines a Distinct Inflammatory Response.

Background: Descriptions of eosinophils in transbronchial biopsy (TBBx) pathology reports after lung transplantation (LTx) are associated with poor long-term outcomes. The absence of routine reporting and standardization precludes accurate assessment of this histologic predictor. A systematic reporting scheme for the presence of TBBx eosinophils after LTx was implemented.

Robotic-assisted total knee arthroplasty reduces soft-tissue releases which improves functional outcomes: A retrospective study.

Background: There is increasing use of Robotic-Assisted (RA) and personalized alignment techniques in total knee arthroplasty (TKA). The hypothesis of this study was that RA TKA would result in fewer soft-tissue releases, and that fewer soft-tissue releases would be associated with improved clinical outcomes.

Methods: A retrospective review of an internal company registry was conducted for all primary TKAs performed from Jan 1, 2014, through a database extract date of Nov 4, 2022.
