Intraoperative Epoprostenol in Type II Heparin-Induced Thrombocytopenia During Left-Ventricular Assist Device Implantation: A Case Series and Review of Literature.

Type II heparin-induced thrombocytopenia and thrombosis (type II HITT) is a rare but serious complication in patients receiving heparin for anticoagulation. In type II HITT, an immune-mediated reaction against platelet factor four-heparin complexes results in thrombocytopenia and an elevated risk of thrombosis. This poses significant challenges for patients with advanced heart failure requiring urgent left-ventricular assist device (LVAD) implantation.

Cardiothoracic operating room blood gas workflow performance improvement initiative.

Objectives: To evaluate the current workflow of blood gas ordering and testing in a cardiothoracic operating room to identify opportunities to streamline the process, using performance improvement methodologies.

Methods: Issues with specimen relabeling were identified that lead to delayed results and potential patient safety concerns. Blood gas specimen relabeling was evaluated for operating room cases from August 2018 to December 2022.

Economic Evaluations of Establishing Opioid Overdose Prevention Centers in 12 North American Cities: A Systematic Review.

Objectives: Overdose prevention centers (OPCs) provide a safe place where people can consume preobtained drugs under supervision so that a life-saving medical response can be provided quickly in the event of an overdose. OPCs are programs that are established in Canada and have recently become legally sanctioned in only a few United States jurisdictions.

Methods: We conducted a systematic review that summarizes and identifies gaps of economic evidence on establishing OPCs in North America to guide future expansion of OPCs.

DEXTENZA versus Topical Steroid or Antihistamine Therapy for Treatment of Allergic Conjunctivitis.

Purpose: To compare clinical outcomes and patient preference for the dexamethasone intracanalicular insert (DEX) versus topical loteprednol (LOT) or olopatadine (OLO) for the treatment of allergic conjunctivitis in a real-world model of allergen exposure.

Methods: This was a prospective comparative trial. Adults with testing-confirmed bilateral allergic conjunctivitis received DEX in the more symptomatic eye and either LOT 2 times daily or OLO once daily for 30 days in the fellow eye.

Cessation of grazing causes biodiversity loss and homogenization of soil food webs.

There is widespread concern that cessation of grazing in historically grazed ecosystems is causing biotic homogenization and biodiversity loss. We used 12 montane grassland sites along an 800 km north-south gradient across the UK, to test whether cessation of grazing affects local - and -diversity of below-ground food webs. We show cessation of grazing leads to strongly decreased -diversity of most groups of soil microbes and fauna, particularly of relatively rare taxa.
