Alpha-gal (AG) allergy is an IgE-mediated allergic reaction to galactose-alpha-1,3-galactose found in mammalian meat. Heparin, being derived from porcine intestinal tissue, may have a degree of cross-reactivity with AG antigen and thus place patients at risk for allergic and even anaphylactic reactions. This is especially important in patients with myocardial infarction (MI) and mechanical circulatory support, such as a left ventricular assist device (LVAD), since anticoagulation is immediately required.

Surgical smoke evacuators may reduce the concentration of alcohol vapors from skin preparations at the site of electrosurgical device activation, decreasing operating room fire risk. Our aim was to compare the incidence of flames with and without smoke evacuation in a porcine ex vivo model. A monopolar device was activated after application of either 70% isopropyl alcohol/2% chlorhexidine gluconate (CHG-IPA) or 74% isopropyl alcohol/0.

The objective of this feasibility study was to determine the extent to which data from randomized controlled trials (RCTs) may serve as a useful source for collecting health care resource use (HCRU) for the purposes of estimating costs of managing adverse events (AEs), specifically, grade 3-4 nausea and thrombocytopenia, which may be experienced during chemotherapy treatment. The feasibility study was conducted in four steps: (1) HCRU data were extracted from patient narratives in four phase 3 RCTs in non-small cell lung cancer; (2) missing HCRU data were imputed; (3) unit costs were applied to the resulting HCRU data set and costs of managing AEs were estimated; and (4) the overall utility of using RCT data as a source for estimating costs of AEs was evaluated. 33 nausea and 68 thrombocytopenia AEs met eligibility criteria and were evaluated in this study.

Introduction: The majority of older patients with a transtibial amputation are prescribed a standard (more rigid, not self-aligning) prosthesis. These are mostly suitable for level walking, and cannot adjust to different sloped surfaces. This makes walking more difficult and less energy efficient, possibly leading to longer term disuse.
