The effect of vascular health factors on white matter microstructure mediates age-related differences in executive function performance.

Cortex 2021 May 25;141:403-420. Epub 2021 May 25.

The University of Texas at Dallas, School of Behavioral and Brain Sciences, Center for Vital Longevity, Dallas, TX, USA. Electronic address:

Even within healthy aging, vascular risk factors can detrimentally influence cognition, with executive functions (EF) particularly vulnerable. Fronto-parietal white matter (WM) connectivity in part, supports EF and may be particularly sensitive to vascular risk. Here, we utilized structural equation modeling in 184 healthy adults (aged 20-94 years of age) to test the hypotheses that: 1) fronto-parietal WM microstructure mediates age effects on EF; 2) higher blood pressure (BP) and white matter hyperintensity (WMH) burden influences this association.

Same-day discharge arthroplasty has a higher overall complications rate than fast-track arthroplasty: a systematic review and meta-analysis.

Arch Orthop Trauma Surg 2021 Jun 15. Epub 2021 Jun 15.

Department of Orthopedics, Orthopedic Research Institute, West China Hospital, Sichuan University, 37# Guoxue Road, 610041, Chengdu, Sichuan, People's Republic of China.

Background: Published studies have reported many inconsistent results regarding the comparison of same-day discharge total joint arthroplasty (TJA) and inpatient TJA. More notably, many recent studies comparing same-day discharge TJA with fast-track TJA presented higher rates of complications for same-day discharge TJA, which raises concerns about the safety of same-day discharge TJA.

Methods: We systematically searched the MEDLINE, Embase, and Cochrane Central Register of Controlled Trials databases up to June 2020 for studies comparing mortality, readmission, and complications in same-day discharge and inpatient total hip or knee arthroplasty. Read More

Perioperative Statin Use May Reduce Postoperative Arrhythmia Rates After Total Joint Arthroplasty.

J Arthroplasty 2021 May 25. Epub 2021 May 25.

Department of Orthopaedic Surgery, Stanford Hospital and Clinics, Redwood City, CA.

Background: Postoperative arrhythmias are associated with increased morbidity and mortality in total joint arthroplasty (TJA) patients. HMG-CoA (3-hydroxy-3-methyl-glutaryl-CoA) reductase inhibitors (statins) decrease atrial fibrillation rates after cardiac surgery, but it is unknown if this cardioprotective effect is maintained after joint reconstruction surgery. We aim to determine if perioperative statin use decreases the incidence of 90-day postoperative arrhythmias in patients undergoing primary TJA. Read More
