Cardiovascular Disease, Drug Therapy, and Mortality in Covid-19.
Coronavirus disease 2019 (Covid-19) may disproportionately affect people with cardiovascular disease. Concern has been aroused regarding a potential harmful effect of angiotensin-converting-enzyme (ACE) inhibitors and angiotensin-receptor blockers (ARBs) in this clinical context. ⋯ Our study confirmed previous observations suggesting that underlying cardiovascular disease is associated with an increased risk of in-hospital death among patients hospitalized with Covid-19. Our results did not confirm previous concerns regarding a potential harmful association of ACE inhibitors or ARBs with in-hospital death in this clinical context.

Hydroxychloroquine or chloroquine with or without a macrolide for treatment of COVID-19: a multinational registry analysis.
Hydroxychloroquine or chloroquine, often in combination with a second-generation macrolide, are being widely used for treatment of COVID-19, despite no conclusive evidence of their benefit. Although generally safe when used for approved indications such as autoimmune disease or malaria, the safety and benefit of these treatment regimens are poorly evaluated in COVID-19. ⋯ William Harvey Distinguished Chair in Advanced Cardiovascular Medicine at Brigham and Women's Hospital.

Randomized Controlled Trial Comparative Study Retracted Publication
Thoracolumbar interfascial plane block provides effective perioperative pain relief for patients undergoing lumbar spinal surgery; a prospective, randomized and double blinded trial.
Background: Although bilateral ultrasound-guided thoracolumbar interfascial plane (TLIP) block provides effective analgesia to the lumbar spinal region, a few previous studies for the TLIP block have only been reported up to the present. We aimed to study whether the TLIP block in combination with general anesthesia would provide more effective pain relief compared to general anesthesia alone. ⋯ Bilateral TLIP block combined with general anesthesia provides more effective perioperative pain relief than that provided by general anesthesia alone in patients who undergo lumbar spinal surgery.
