New records of rove beetles from the Province of Quebec, and additional provincial records in Canada (Coleoptera, Staphylinidae).

We newly report 25 provincial records of rove beetles (Coleoptera: Staphylinidae) from the province of Quebec from the following subfamilies: Steninae (1), Euaesthetinae (1), Omaliinae (2), Oxyporinae (1), Paederinae (1), Proteininae (1), Pselaphinae (2), Scaphidiinae (2), Scydmaeninae (2), Staphylininae (11) and Tachyporinae (1). Among these, two species are also reported for the first time from Ontario, two from Nova Scotia, and five are new Canadian records. We also report the first supporting data for (Fabricius, 1792) and Erichson, 1840 for Quebec, and of Fauvel, 1878, (Fauvel, 1878), and (Erichson, 1839) for Ontario.

Total Hip Arthroplasty: Direct Anterior Approach Versus Posterior Approach in the First Year of Practice.

Background: The direct anterior approach (DAA) for total hip arthroplasty (THA) has been popularized as a less invasive technique, however outcomes within the first year of practice after fellowship have not been investigated. The primary aim was to determine differences in complications and outcomes between DAA and posterior approach (PA) in the first year of practice. The secondary aim was to determine if there was a learning curve factor in DAA and PA after fellowship training.

Preoperative Opioid Usage, Male Sex, and Preexisting Knee Osteoarthritis Impacts Opioid Refills After Isolated Arthroscopic Meniscectomy: A Population-Based Study.

Purpose: To identify risk factors for opioid consumption after arthroscopic meniscectomy using a large national database.

Methods: Patients undergoing primary arthroscopic meniscectomy from 2007 to 2016 were retrospectively accessed from the Humana database. Patients were categorized as those who filled opioid prescriptions within 3 months (OU), within 1 month (A-OU), between 1 and 3 months (C-OU), and never filled opioid prescriptions (N-OU) before surgery.

Medicare's Hospital-Acquired Conditions Policy: A Problem of Nonpayment After Total Joint Arthroplasty.

Background: Total joint arthroplasty (TJA) utilization continues to increase, and optimizing efficiency while reducing complications is critical to provide a sustainable product. Recent policy has defined several hospital-acquired conditions (HACs) that are the target of reducing complications with significant financial implications. The present study defines the incidence of HACs after TJA as well as patient and hospital factors associated with HACs.
