Understanding the Value of Total Shoulder Arthroplasties at Physician-Owned Hospitals.

J Am Acad Orthop Surg 2020 Dec;28(23):e1066-e1072

From the Department of Orthopaedics, The Ohio State University Wexner Medical Center, Columbus, OH.

Background: Owing to concerns regarding higher cost, low quality of care and cherry-picking in physician-owned hospitals (POHs), the Affordable Care Act imposed sanctions that prevented the formation of new POHs. With an increasing utilization of total shoulder arthroplasties (TSAs), there is a need for re-evaluation and assessment of quality and cost of TSAs performed at these POHs.

Methods: The 2011 to 2014 Medicare 100% Standard Analytical Files was used to identify patients undergoing a reverse TSA or anatomic TSA at POHs and non-POHs. Read More

PLoS One 2021 7;16(5):e0251260. Epub 2021 May 7.

Institute and Policlinic of Occupational and Social Medicine (IPAS), Faculty of Medicine Carl Gustav Carus, TU Dresden, Germany.

Introduction: Work-life conflicts (WLC) may impact health, but few studies prospectively consider the impact of WLC on objective outcomes such as cardiovascular disease. Using data from the Gutenberg Health Study (GHS), we examined if WLC at baseline was associated with an increased five-year incidence of cardiovascular events (myocardial infarct, stroke, atrial fibrillation, peripheral artery disease, coronary artery disease, chronic heart failure, sudden cardiac death). We also considered if WLC was associated with incident hypertension and arterial stiffness and if the effects of WLC on cardiovascular health differ for men and women. Read More

Coronary Microvascular Adaptations Distal to Epicardial Artery Stenosis.

Am J Physiol Heart Circ Physiol 2021 May 7. Epub 2021 May 7.

Department of Physiology and Pharmacology and Michael E. DeBakey Institute for Comparative Cardiovascular Science and Biomedical Devices, College of Veterinary Medicine and Biomedical Sciences, Texas A&M University, College Station, TX 77843, United Statesgrid.264756.4.

Until recently, epicardial coronary stenosis has been considered the primary outcome of coronary heart disease and clinical interventions have been dedicated primarily to identification and removal of flow-limiting stenoses. However, a growing body of literature indicates that both epicardial stenosis and microvascular dysfunction contribute to damaging myocardial ischemia. In this review, we discuss the co-existence of macro- and microvascular disease, and how the structure and function of the distal microcirculation is impacted by the hemodynamic consequences of an epicardial, flow-limiting stenosis.

Colchicine and the heart.

Eur Heart J 2021 May 7. Epub 2021 May 7.

GenesisCare, 3/140 Mounts Bay Rd, Perth, Western Australia, Australia.

Colchicine is a unique, sophisticated anti-inflammatory agent that has been used for decades for the prevention of acute inflammatory flares in gout and familial Mediterranean fever. In recent years, clinical trials have demonstrated its potential in a range of cardiovascular (CV) conditions. Colchicine is avidly taken up by leucocytes, and its ability to bind to tubulin and interfere with microtubular function affects the expression of cytokines and interleukins, and the ability of neutrophils to marginate, ingress, aggregate, express superoxide, release neutrophil extracellular traps, and interact with platelets.
