Background: Patients with skin and soft tissue infections (SSTIs) are often admitted by the emergency department for intravenous antibiotic therapy and surgical drainage of abscesses if necessary. As part of the initial diagnostic workup, blood cultures are routinely drawn at our institution in patients with SSTIs. This study seeks to identify the utility of performing blood cultures in patients with upper extremity abscesses as it relates to the number of incision and drainage (I&D) procedures performed, patient readmission rates, and length of hospital stay.

Background: Breast implant illness (BII) is a term popularized by social media to describe systemic symptoms that patients ascribe to their breast implants. Though the concept of implants as an underlying cause for a systemic illness remains controversial, few studies have delineated the implant characteristics, capsular histology, and outcomes of patients who undergo explantation for BII.

Methods: We retrospectively reviewed the demographics, presenting symptoms, outcomes, capsular histology, and culture results of all women who presented to the senior author with symptoms attributed to BII and underwent breast implant removal with capsulectomy from August 2016 to February 2020.

Background: Prior research suggests that physician attire has an important effect on patient perceptions, and can influence the patient-physician relationship. Previous studies have established the effect of specialty, location, and setting on patient preferences for physician attire, and the importance of these preferences and perceptions on both the physician-patient relationship and first impressions. To date, no studies have examined the influence of attire in the inpatient orthopaedic surgery setting on these perceptions.

Impaired fundic accommodation (FA) limits fundic relaxation and the ability to act as a reservoir for food. Assessing intragastric meal distribution (IMD) during gastric emptying scintigraphy (GES) allows for a simple measure of FA. The 3 goals of this study were to evaluate trained readers' (nuclear medicine and radiology physicians) visual assessments of FA from solid-meal GES; develop software to quantify GES IMD; and correlate symptoms of gastroparesis with IMD and gastric emptying.

Objectives: The present study was undertaken to test the hypothesis that gene delivery of BCL2-Associated Athanogene 3 (BAG3) to the heart of mice with left ventricular dysfunction secondary to a myocardial infarction could enhance cardiac performance.

Background: BAG3 is a 575 amino acid protein that has pleotropic functions in the cell including pro-autophagy and anti-apoptosis. Mutations in BAG3 have been associated with both skeletal muscle dysfunction and familial dilated cardiomyopathy and BAG3 levels are diminished in non-familial heart failure.

Bcl-2-associated athanogene 3 (BAG3) is an evolutionarily conserved protein expressed at high levels in the heart and the vasculature and in many cancers. While altered BAG3 expression has been associated with cardiac dysfunction, its role in ischemia/reperfusion (I/R) is unknown. To test the hypothesis that BAG3 protects the heart from reperfusion injury, in vivo cardiac function was measured in hearts infected with either recombinant adeno-associated virus serotype 9-expressing (rAAV9-expressing) BAG3 or GFP and subjected to I/R.

Regulatory mechanisms underlying constitutive and inducible NFκB activation in cancer remain largely unknown. Here we investigated whether a novel NIK- and IKK2-binding protein (NIBP) is required for maintaining malignancy of cancer cells in an NFκB-dependent manner. Real-time polymerase chain reaction analysis of a human cancer survey tissue-scan cDNA array, immunostaining of a human frozen tumor tissue array and immunoblotting of a high-density reverse-phase cancer protein lysate array showed that NIBP is extensively expressed in most tumor tissues, particularly in breast and colon cancer.
