Surrogates of Muscle Mass on Cardiac MRI Correlate with Exercise Capacity in Patients with Fontan Circulation.

Background: Sarcopenia is an increasingly recognized marker of frailty in cardiac patients. Patients with a history of congenital heart disease and Fontan procedure have a higher risk of developing progressive muscle wasting. Our objective was to determine if we could use routine cardiac MRI (CMR) for the surveillance of muscle wasting.

Shift Work and Obesity Risk-Are There Sex Differences?

Purpose Of Review: Shift work is prevalent among the working population and is linked to an array of adverse health outcomes. This review summarizes current evidence on the relation between shift work and risk of obesity, with a particular emphasis on potential sex differences.

Recent Findings: Observational data strongly point towards an association between shift work and heightened risk of prevalent and incident obesity, and particularly abdominal obesity.

Multireader evaluation of radiologist performance for COVID-19 detection on emergency department chest radiographs.

Background: Chest radiographs (CXR) are frequently used as a screening tool for patients with suspected COVID-19 infection pending reverse transcriptase polymerase chain reaction (RT-PCR) results, despite recommendations against this. We evaluated radiologist performance for COVID-19 diagnosis on CXR at the time of patient presentation in the Emergency Department (ED).

Materials And Methods: We extracted RT-PCR results, clinical history, and CXRs of all patients from a single institution between March and June 2020.

Normative and isolated rapid eye movement sleep without atonia in adults without REM sleep behavior disorder.

Study Objectives: Values for normative REM sleep without atonia (RSWA) remain unclear. Older age and male sex are associated with greater RSWA, and isolated elevated RSWA has been reported. We aimed to describe normative RSWA and characterize isolated RSWA frequency in adults without REM sleep behavior disorder (RBD).

Trauma-Associated Sleep Disorder: A Posttraumatic Stress/REM Sleep Behavior Disorder Mash-Up?

Abstract: Trauma-associated sleep disorder (TASD) is a parasomnia sharing characteristics of post-traumatic stress disorder (PTSD) and REM sleep behavior disorder (RBD) including dream-enactment behavior (DEB). Here we report REM sleep without atonia (RSWA) and other neurological features in a patient with complex vocal and motor DEB following traumatic combat military exposure. Post-discharge, his wife observed frequent yelling and jerking during sleep with dream mentation reminiscent of traumatic military experiences.

Multimodal Analgesia in Breast Surgical Procedures: Technical and Pharmacological Considerations for Liposomal Bupivacaine Use.

Enhanced recovery after surgery is a multidisciplinary perioperative clinical pathway that uses evidence-based interventions to improve the patient experience as well as increase satisfaction, reduce costs, mitigate the surgical stress response, accelerate functional recovery, and decrease perioperative complications. One of the most important elements of enhanced recovery pathways is multimodal pain management. Herein, aspects relating to multimodal analgesia following breast surgical procedures are discussed with the understanding that treatment decisions should be individualized and guided by sound clinical judgment.

Sinusitis Treatment Guideline Adherence in the E-Visit Setting: A Performance Improvement Project.

Background: Studies demonstrate poor guideline adherence by health care providers for the treatment of upper respiratory infections, particularly acute bacterial rhinosinusitis (ABRS), in the appropriate prescribing of antibiotic medications.

Objective: The purpose of this quality improvement project was to evaluate the effect of implementing interventions for improving adherence to a clinical practice guideline for the management of ABRS for patients treated in the e-visit setting. Interventions included: providing a report to providers of their adherence to the ABRS clinical guideline prior to the intervention, providing updated education on the ABRS guideline, and implementing a clinical decision support system reminder.

Anesthesia duration as a marker for surgical complications in office-based plastic surgery.

Background: Office-based plastic surgery has continued to rise in the past 2 decades with the increased demand for cosmetic surgery. Although several large studies have shown the safety of office-based surgery, current regulations place some restrictions on ambulatory office-based surgical facilities. To provide further evidence-based literature on the safety of office-based plastic surgery, we examine surgical complication rates as a function of anesthesia duration.

Quality of care in the retail health care setting using national clinical guidelines for acute pharyngitis.

Rates of adherence to an acute pharyngitis practice guideline in the retail clinic setting were measured as an indicator of clinical quality. An analysis of 57,331 patient visits for the evaluation of acute pharyngitis was conducted. In 39,530 patients with a negative rapid strep test result, nurse practitioner and physician assistant staff adhered to guidelines in 99.

Direct injection of blood into the labrum enhances the stability provided by the glenoid labral socket.

We tested the hypothesis that the stabilizing function of the labrum can be enhanced by inflating it with blood. In 6 fresh cadaveric glenoids, the anteroinferior stability provided by the glenoid was quantitated by measuring the maximal angle between the glenoid centerline and the direction of the force applied via a ball in the glenoid before the ball dislocated from the glenoid. This stability angle was measured for each of 4 different applied loads.

The effect of total shoulder arthroplasty on self-assessed deficits in shoulder function in patients with capsulorrhaphy arthropathy.

The objective of this study was to characterize self-assessed functional deficits before and after total shoulder arthroplasty (TSA) in a consecutive series of 24 patients treated for capsulorrhaphy arthropathy. Deficits were determined by use of the Simple Shoulder Test. The effects of age, type of original stabilization surgery, duration of time since the initial repair, and pattern of glenoid erosion were analyzed.

Deficits in shoulder function and general health associated with sixteen common shoulder diagnoses: a study of 2674 patients.

The purpose of this study is to define the self-assessed deficits in function and general health perceived by a large cohort of patients with common shoulder diagnoses. For a 10-year period, all new shoulder patients presenting to the senior author were characterized by diagnosis, age, gender, and self-assessed shoulder function and general health status. This report concerns the 2674 patients having 1 of the 16 most prevalent diagnoses.

Do progressive tension sutures really decrease complications in abdominoplasty?

The purpose of this study is to evaluate the efficacy of progressive tension sutures (PTS) in preventing or reducing seroma formation and local wound complications in patients undergoing abdominoplasty. Forty-nine patients who underwent abdominoplasty procedures with the use of PTS were retrospectively compared with a historical control group of 54 patients who underwent standard abdominoplasty. Primary outcomes measured were seroma formation and local wound complications, including hypertrophic scar formation, umbilical distortion, and wound necrosis.

Characterizing the effect of diagnosis on presenting deficits and outcomes after total shoulder arthroplasty.

This study compared self-assessed deficits in comfort, function, and health status before and after total shoulder arthroplasty for 4 different diagnoses: degenerative joint disease (DJD), secondary DJD (2 degrees DJD), rheumatoid arthritis (RA), and capsulorrhaphy arthropathy (CA). Deficits were assessed by the Simple Shoulder Test and Short Form 36 (SF-36) questionnaires. There was a significant difference among diagnoses for preoperative and postoperative functional deficits.

Patient functional self-assessment in late glenoid component failure at three to eleven years after total shoulder arthroplasty.

Failure of the glenoid component is the most common indication for late revision of a total shoulder arthroplasty (TSA). This is the first study to characterize the deterioration in patient self-assessment of shoulder function occurring with glenoid component failure at times remote from the index surgery. Of 115 total shoulders, 11 had revision by the original surgeon for isolated glenoid loosening.

Optimizing the glenoid contribution to the stability of a humeral hemiarthroplasty without a prosthetic glenoid.

Background: In a shoulder requiring arthroplasty, if the glenoid is flat or biconcave, the surgeon can restore the desired glenoid stability by using a glenoid prosthesis with a known surface geometry or by modifying the surface of the glenoid to a geometry that provides the desired glenoid stability. This study tested the hypotheses that (1) the stability provided by the glenoid is reduced by the removal of the articular cartilage; (2) the stability contributed by the glenoid is compromised by loss of its articular cartilage, and this lost stability can be restored by spherical reaming along the glenoid centerline; and (3) the stability of a reamed glenoid is comparable with that of a native glenoid and with that of a polyethylene glenoid with similar surface geometry; and (4) the glenoid stability can be predicted from the glenoid surface geometry.

Methods: The stability provided by the glenoid in a given direction can be characterized by the maximal angle that the humeral joint reaction force can make with the glenoid centerline before the humeral head dislocates; this quantity is defined as the balance stability angle in the specified direction.

Glenohumeral arthritis and its management.

Glenohumeral arthritis has many different etiologies, including osteo-arthritis, secondary degenerative joint disease, rheumatoid arthritis,avascular necrosis, cuff tear arthropathy, and capsulorrhaphy arthropathy. Each of these diagnoses may have different underlying pathoanatomy and pathomechanics. The treating physician must recognize how these characteristics impair shoulder function so that the prescribed course of treatment addresses the root causes of shoulder dysfunction.

The distribution of shoulder replacement among surgeons and hospitals is significantly different than that of hip or knee replacement.

Practice is the repetition of an action to improve its quality. The value of the practice effect is recognized in sports, music, and surgery. The number of times a surgical procedure is performed may have a bearing on how well it is done.

A prospective multipractice investigation of patients with full-thickness rotator cuff tears: the importance of comorbidities, practice, and other covariables on self-assessed shoulder function and health status.

Background: Rotator cuff tears are among the most common conditions of the shoulder. One of the major difficulties in studying patients with rotator cuff tears is that the clinical expression of these tears varies widely and different practices may have substantially different patient populations. The goals of the present prospective multipractice study were to use patient self-assessment questionnaires (1) to identify some of the characteristics of patients with rotator cuff tears, other than the size of the cuff tear, that are correlated with shoulder function, and (2) to determine whether there are significant differences in these characteristics among patients from the practices of different surgeons.
