Introduction: Little research has investigated the relationship between musculoskeletal pain and body mass index (BMI) in the context of pain-associated psychological distress. This study aims to determine if independent associations exist between BMI, obesity, demographic variables, and psychological distress in patients presenting with hip pain.

Materials And Methods: Using a retrospective cross-sectional study design, 428 patients completed the Optimal Screening for Prediction of Referral and Outcome Yellow Flag (OSPRO-YF) and were categorized into pain-associated psychological distress phenotypes using latent class analysis.

Article Synopsis
  • A study analyzing intraoperative EEG data from 1,081 patients found that higher alpha power (8-12Hz) during surgery is associated with lower post-operative mortality and better cognitive outcomes.
  • The research indicated significant correlations between alpha power and mortality within various time frames: 30, 90, 180 days, and 1 year post-surgery.
  • These findings suggest that measuring intraoperative EEG alpha power could be a valuable tool for predicting patient outcomes and improving perioperative risk assessment.

Article Synopsis
  • Late identification of SARS-CoV-2 outbreaks in long-term care homes is linked to higher rates of secondary infections and mortality among residents.
  • A study of outbreaks in Ontario from March to November 2020 showed that 36.4% were identified late, leading to significantly increased infection (10.3%) and mortality rates (3.2%) compared to early identified outbreaks (3.3% and 0.9% respectively).
  • The findings suggest timely outbreak identification is crucial for better management and response to respiratory infections in LTC homes, helping to reduce adverse effects on residents.

Chondral defects in the athlete's hip are a relatively common occurrence, often presenting with debilitating pain and activity limitation. Preoperative identification of cartilage defects is challenging and there are many different modalities for treatment. Nonsurgical interventions, including activity modification, physical therapy, and injections, play a vital role, especially in less severe cases and as adjuncts to surgical intervention.

The average time to degree for completing a life sciences PhD in the United States is longer for single-degree than dual-degree trainees, supporting a perception that the PhD training of MD-PhDs is less rigorous or fulsome. To determine whether degree format influences the duration and impact of graduate training, we analyzed data for the 2011-2016 graduates of 3 Harvard Medical School PhD programs. Linear mixed effects models were used to determine the association between degree type (MD-PhD vs.

At present, Ontario, like most other jurisdictions in Canada, uses a syndromic-based surveillance definition for acute respiratory infection (ARI) outbreaks in institutions and public hospitals. Confirmed outbreaks are defined as either two or more ARIs in 48 hours with any common epidemiological link and at least one that is laboratory-confirmed; or three cases of ARIs occurring within 48 hours with any common epidemiological link, and not necessarily with lab confirmation. However, with the adoption of broader test-based approaches for sick patients/residents throughout the pandemic, new challenges have surfaced regarding the declaration and management of ARI outbreaks with a variety of scenarios in respiratory testing results.

Hip arthroscopy continues to increase in popularity and has an ever-expanding range of indications; however, the steep learning curve introduces significant risk of iatrogenic chondrolabral injury when accessing the joint and establishing arthroscopic portals. This article presents a technique for establishing the modified midanterior portal and is particularly useful when the available space is tight. We present "the air-lift" as a safe and simple adjunct to standard portal creation when performing hip arthroscopy in the supine position.

Background: Mental health characteristics such as negative mood, fear avoidance, unhelpful thoughts regarding pain, and low self-efficacy are associated with symptom intensity and capability among patients with hip and knee osteoarthritis (OA). Knowledge gaps remain regarding the conceptual and statistical overlap of these constructs and which of these are most strongly associated with capability in people with OA. Further study of these underlying factors can inform us which mental health assessments to prioritize and how to incorporate them into whole-person, psychologically informed care.

Preoperative knowledge of expected postoperative pain can help guide perioperative pain management and focus interventions on patients with the greatest risk of acute pain. However, current methods for predicting postoperative pain require patient and clinician input or laborious manual chart review and often do not achieve sufficient performance. We use routinely collected electronic health record data from a multicenter dataset of 234,274 adult non-cardiac surgical patients to develop a machine learning method which predicts maximum pain scores on the day of surgery and four subsequent days and validate this method in a prospective cohort.

Patient-reported outcome (PRO) measures offer a unique opportunity to systematically incorporate patient perspectives of their health and wellbeing into treatment, view progress over time, and develop opportunities related to clinical decision support, shared decision making, and outcomes-driven payment and practice transformation. As healthcare institutions increasingly look toward adopting PRO measures in their practices, more information is needed regarding the practicalities of implementing a successful PRO program outside of the research setting. This article offers a stepwise approach to implementing a PRO program while overcoming barriers and leveraging facilitators that commonly exist in the realms of human contribution or team building, technological infrastructure, and process design.
