The coronavirus-19 (COVID-19) pandemic has been an unprecedented time for healthcare and has substantially changed resource availability in surgeons' work practices and routines. Many orthopaedic departments suspended elective surgery, and some re-deployed orthopaedic residents to stressful nonorthopaedic tasks; long hours were commonplace. Stress-reaction symptoms such as anxiety and depression have been reported in about 10% of healthcare workers during previous infectious-diseases outbreaks (including the Ebola virus), but little is known about the psychological needs of residents faced with this global disaster.

(1) Have anxiety and depression symptoms among orthopaedic residents worsened from the period before to the period after the lockdown in Italy? (2) Are there differences in anxiety and depression symptoms between residents who worked in a COVID-19 department and those who did not?

The Italian Association of Orthopaedic and Traumatology Residents is comprised of 365 members who were recruitedy and depression, over time, for residents who worked in a COVID-19 department compared with those who did not. The evaluation of anxiety and depression through standardized questionnaires could help to identify residents at risk of higher psychological distress who could be referred to regular psychological counseling as a possible prevention strategy during stressful times. Future studies should confirm the long-term effects of these findings.

Postoperative gait speed, especially comfortable gait speed, is an important factor for predicting function after total hip arthroplasty (THA). In this study, we examined factors related to gait speed, including preoperative lower and upper-limb functional parameters and postoperative lower-limb alignment. In addition, we examined factors related to postoperative good comfortable gait speed (≥1.34 m/s one indicator of a good clinical outcome). The purpose of this study was to determine if better preoperative functional parameters had a positive effect on postoperative gait speed.

This prospective case-control study included 91 patients with hip osteoarthritis who underwent unilateral THA. Patients who had undergone a prior hip surgical procedure or had Crowe type-3 and 4 hips, complications after THA, knee osteoarthritis-related pain, and severe lumbar conditions were excluded. The 1-leg standing time (OLST) and knee extensor strength of the operatively treated side and the contralateral side and the funcnificant factor (p = 0.027) for preoperative comfortable gait speed.

The preoperative contralateral-side, lower-limb functional status is a significant factor for postoperative gait speed. Early surgical intervention before the contralateral-side function declines or a preoperative rehabilitation intervention on the contralateral side may improve THA outcome.

Women have historically been underrepresented as editors of peer-reviewed medical journals. Studies have demonstrated that there are differences in editorial board reviewer behavior based on gender, suggesting that greater representation by women on editorial boards may improve the quality and diversity of the review process. Therefore, the current representation of women on the editorial boards of orthopaedic journals, particularly compared with peer-reviewed surgical and medical journals, is of interest.

(1) What is the representation of women as members of editorial boards of prominent orthopaedic surgery journals? (2) How does it compare with representation on the editorial boards of journals in general surgery and internal medicine?

The top 15 journals with a strong clinical emphasis based on Impact Factor (Clarivate Analytics) calculated by the 2018 Journal Citation Reports were identified for orthopaedic surgery, general surgery (and all general surgical subspecialties), and internal medicine (wireasing representation of women on editorial boards may improve the diversity of perspectives and quality of future published research, generate visible role models for young women considering orthopaedics as a career, and improve patient care through enriching the diversity of our specialty.
Patients with existing coronary artery stents are at an increased risk for major adverse cardiac events (MACEs) when undergoing noncardiac surgery (NCS). Although the use of antifibrinolytic (AF) therapy in NCS has significantly increased in the past decade, the relationship between perioperative AF use and its association with MACEs among patients with existing coronary artery stents has yet to be assessed. In this study, we aim to evaluate the association of MACEs in patients with existing coronary artery stents who receive perioperative AF therapy during orthopedic surgery.

A single-center retrospective cohort study was conducted in adult patients with existing coronary artery stents who underwent orthopedic surgery from 2008 to 2018. Two cohorts were established patients with existing coronary artery stents who did not receive perioperative AF and patients with coronary artery stents who received perioperative AF. Associations between AF use and the primary outcome of MACEs within 30 days postoperativospective studies, powered to detect differences in MACEs, are needed to assess the safety of perioperative AF in patients with existing coronary artery stents and to clarify the mechanism of perioperative MACEs in this high-risk population.
As part of a market-driven response to the increasing costs of hospital-based surgical care, an increasing volume of orthopaedic procedures are being performed in ambulatory surgery centers (ASCs). The purpose of the present study was to identify recent trends in orthopaedic ASC procedure volume, utilization, and reimbursements in the Medicare system between 2012 and 2017.

This cross-sectional, national study tracked annual Medicare claims and payments and aggregated data at the county level. Descriptive statistics and multivariate regression models were used to evaluate trends in procedure volume, utilization rates, and reimbursement rates, and to identify demographic predictors of ASC utilization.

A total of 1,914,905 orthopaedic procedures were performed at ASCs in the Medicare population between 2012 and 2017, with an 8.8% increase in annual procedure volume and a 10.5% increase in average reimbursements per case. ASC orthopaedic procedure utilization, including utilization across all subspecialtiesrocedure volume in recent years, driven by increases in hand procedure volume. Medicare reimbursements per case have steadily risen and outpaced the rate of inflation over the study period. However, as orthopaedic practice overhead continues to increase, other Medicare expenditures such as hospital payments and operational and implant costs also must be evaluated. These findings may provide a source of information that can be used by orthopaedic surgeons, policy makers, investors, and other stakeholders to make informed decisions regarding the costs and benefits of the use of ASCs for orthopaedic procedures.Arterial blood gas (ABG) analysis is used in critical care units to determine the degree of oxygenation, adequacy of ventilation, and the presence and severity of acid-base disturbances in the body. However, arterial puncture may result in complications, and the difficulty in acquiring arterial blood may delay care. Central venous blood gas (VBG) is a potentially more accessible alternative to ABG sampling. Current evidence suggests that pH and Pco2 obtained via peripheral VBG correlate well with ABG measurement. Nevertheless, the value of using central VBG to guide clinical decisions or as a surrogate for ABG is unclear. The purpose of this review is to explore the relationship between ABGs and central VBGs in critically ill patients. We performed a MEDLINE search using the following search terms venous blood gas, arterial blood gas, and central venous blood gas. We excluded studies that did not involve human subjects, and only pH and Pco2 values were reviewed and examined from the studies included. All cited references from included studies were also reviewed to identify relevant literature. We identified 7 studies that met our criteria. In studies of hemodynamically stable patients, the mean difference between arterial and central venous pH and Pco2 was 0.03 units and 4-6.5 mm Hg, respectively. However, in patients with circulatory failure, the difference between central venous and arterial pH/Pco2 was 4-fold greater. We concluded that central VBG parameters of pH and Pco2 are potentially good surrogates for determining arterial pH and Pco2 in a stable patient without severe acid-base disturbances. Furthermore, central VBG can be used as a useful screening tool for arterial hypercapnia. In addition, we derived an adjustment formula for ABG conversion from central VBG (1) arterial pH = venous pH + 0.05 units and (2) arterial Pco2 = venous Pco2 - 5 mm Hg.
Watkins, CM, Storey, A, McGuigan, M, and Gill, ND. Implementation and efficacy of plyometric training Bridging the gap between practice and research. J Strength Cond Res 35(5) 1244-1255, 2021-Plyometric training is an effective method for improving speed and acceleration. However, a gap seems to exist between research recommendations and practitioner's actual programs. Some reports suggest as many as 400 jumps per session, while anecdotally some strength and conditioning coaches are using as few as 15-40 jumps even with elite athletes. Thus, the purposes of this study were to obtain a clearer understanding of the practitioner's perspective on plyometric training strategies as compared to literary recommendations and to compare any trends across competition level or sport categories. An integrative mixed-methods model was used. Globally, 61 strength and conditioning practitioners completed an anonymous online survey, containing 5 sections 1.

MacLennan, RJ, Mota, JA, Thompson, BJ, and Stock, MS. Effects of strength and conditioning on maximal isometric strength, motor unit behavior, and concentric isokinetic peak torque in middle-school boys. J Strength Cond Res XX(X) 000-000, 2020-It has long been theorized that improvements in muscle strength in young athletes are mediated by motor unit adaptations. The ability to decompose surface electromyographic signals obtained during isometric contractions now allow for such research questions to be answered. We examined changes in isometric and concentric isokinetic strength, as well as vastus lateralis motor unit behavior, after 16 weeks of strength training and conditioning in middle-school aged boys. Nine boys (mean ± SD age = 12 ± 1 years) participated in training. Five boys (age = 13 ± 1 years) served as control subjects. The training subjects performed 90 minutes of high-intensity, multi-joint exercise twice per week. Assessments of unilateral maximal voluntary isometric contraction (MVIC) force of the knee extensors, concentric peak torque at velocities of 60, 180, and 300°·s-1, and vastus lateralis motor unit data during 50 and 80% MVIC tests were performed.
