Association of Antihypertensive and Statin Medication Usage With Postoperative Stiffness After Arthroscopic Rotator Cuff Repair: A Retrospective Cohort Study.

Background: Angiotensin-converting enzyme inhibitors (ACEi), angiotensin receptor blockers (ARB), and statins may be able to modulate postoperative stiffness, a major cause of morbidity after arthroscopic rotator cuff repair (aRCR).

Purpose: To determine whether there is an association between ACEi, ARB, or statin usage and stiffness after aRCR.

Study Design: Cohort study; Level of evidence, 3.

Lack of gastric emptying at autopsy eleven days after heat trauma in the sauna- a forensic autopsy case report.

A man in his mid-70s passed out in a public 90-degree sauna and remained unconscious for at least half an hour. He suffered third-degree burns to approximately 50% of his body surface area. Despite immediate transport to a burn center and intensive care therapy, he did not regain consciousness and died eleven days later.

Higher socioeconomic status is associated with greater rates of surgical resource utilization prior to spine fusion surgery.

Background Context: Previous research has demonstrated an association between socioeconomic status (SES) and patient health, specifically noting that patients of lower SES have poor health outcomes. Understanding how social factors, including socioeconomic status (SES), relate to disparities in health outcomes is critical to closing gaps in equitable care to patients. While several studies have examined the effect of SES on postoperative spine outcomes, there is limited spine literature evaluating SES in the context of barriers to spine care.

Distal Mononeuropathy and Nerve Release After Open and Arthroscopic Shoulder Surgery: A Matched Cohort Analysis.

Purpose: The purpose of this study was to determine if patients who have undergone prior open or arthroscopic shoulder surgery and develop distal mononeuropathy (DMN) achieve the same clinical benefit after nerve release compared with those who did not have a prior shoulder procedure.

Methods: Patients were identified by Current Procedural Terminology code for shoulder arthroplasty, shoulder stabilization, and rotator cuff repair and if they had an ensuing nerve release (cubital or carpal tunnel) within 2 years of shoulder surgery. Another cohort that underwent nerve release surgery for DMN with no prior history of shoulder surgery was identified and subsequently matched to the first cohort by a 3:1 (control:case) ratio.

CHARMM at 45: Enhancements in Accessibility, Functionality, and Speed.

Since its inception nearly a half century ago, CHARMM has been playing a central role in computational biochemistry and biophysics. Commensurate with the developments in experimental research and advances in computer hardware, the range of methods and applicability of CHARMM have also grown. This review summarizes major developments that occurred after 2009 when the last review of CHARMM was published.
