Article Synopsis
  • - This study aimed to explore the link between semimembranosus tendinosis and medial meniscal tears using MRI scans of patients' knees.
  • - Out of 150 MRI scans, semimembranosus tendinosis was found in 44% of patients, and a significant 81% of those with meniscal tears also had tendinosis.
  • - The research indicated that individuals with semimembranosus tendinosis were seven times more likely to have meniscal tears, which could influence rehabilitation strategies after knee surgeries.

Cohesin mediates the 3-D structure of chromatin and is involved in maintaining genome stability and function. The cohesin core comprises Smc1 and Smc3, elongated-shaped proteins that dimerize through globular domains at their edges, called head and hinge. ATP binding to the Smc heads induces their dimerization and the formation of two active sites, while ATP hydrolysis results in head disengagement.

Background: Matted nodes in human papillomavirus (HPV)-mediated oropharyngeal squamous cell carcinoma (OPC) is an independent predictor of distant metastases and decreased overall survival. We aimed to classify imaging patterns of metastatic lymphadenopathy, analyze our classification system for reproducibility, and assess its prognostic value.

Methods: The metastatic lymphadenopathy was classified based on radiological characteristics for 216 patients with HPV-mediated OPC.

Purpose: Though gabapentin is increasingly used as a perioperative analgesic, data regarding effectiveness in children are limited. The purpose of this study was to evaluate gabapentin as a postoperative analgesic in children undergoing appendectomy.

Methods: A 12-month retrospective review of children undergoing appendectomy was performed at a two-hospital children's institution.

Background: Recommendations regarding performance of magnetic resonance imaging (MRI) in non-MRI conditional pacemaker and defibrillator recipients are evolving. Previous studies have suggested low adverse event rates with MRI in nonconditional cardiac implantable electronic device (CIED) recipients, but low power limits optimal characterization of risk.

Objective: The purpose of this study was to perform a systematic review and meta-analysis to characterize the clinical risk associated with MRI in CIED recipients in order to improve power.

Background: The decision to abandon or extract superfluous sterile leads is controversial.

Objective: The purpose of this study was to compare procedural outcomes and long-term survival of patients with and those without abandoned leads undergoing lead extraction (LE).

Methods: Retrospective review of all patients who had undergone transvenous LE at our institution from January 2007 to May 2016 was performed.

Background: Octogenarians account for a significant percentage of patients with indwelling pacemakers or defibrillators.

Objectives: To determine procedural outcomes and long-term survival after lead extraction (LE) in octogenarians.

Methods: We retrospectively identified all patients who underwent defibrillator or pacemaker LE at our institution between January 1, 2007 and May 31, 2016.

Background: Little is known about advance directive (AD) utilization in implantable cardioverter-defibrillator (ICD) recipients.

Objective: The purpose of this study was to define the prevalence and predictors of ADs in patients with ICDs.

Methods: We identified ICD recipients with ADs at our institution.

Objectives: This study compared risks associated with magnetic resonance imaging (MRI) in patients with non-MRI conditional and MRI conditional pacing and defibrillator systems with particular attention to clinically actionable outcomes.

Background: While recipients of new MRI conditional pacemaker and defibrillator systems may undergo MRI scanning with very low risk, safety and regulatory concerns persist regarding such scanning in recipients of non-MRI conditional systems.

Methods: Patients with any cardiac device who were referred for MRI were prospectively enrolled at a single center and underwent scanning at 1.

Article Synopsis
  • - The study investigates the need and outcomes of using the femoral approach for lead extraction (LE) in patients, finding that only about 5% required this method; it is often used when other approaches fail.
  • - Key predictors for needing femoral extraction included longer lead dwell time, a greater number of leads extracted, and infection as a reason for extraction.
  • - The success rates for femoral extraction were notably lower compared to other methods, indicating that it is usually a last-resort option for more complicated cases.

Background: Extraction of pacemaker and defibrillator leads in young adults may be technically challenging because of more extensive fibrosis and calcification in this patient population.

Objective: The purpose of this study was to examine outcomes of lead extraction (LE) in young adults at our institution.

Methods: We retrospectively identified all patients who underwent LE at our institution between January 1, 2007, and May 31, 2016.

Aims: End-stage renal disease (ESRD) increases the risk of implantable cardioverter-defibrillator (ICD) infection. We sought to define outcomes of lead extraction in patients with ESRD.

Methods And Results: Implantable cardioverter-defibrillator lead extractions at our institution from January 2006 to March 2014 were stratified by absence (Control-Ex, n = 465) or presence (ESRD-Ex, n = 43) of ESRD.

Objective: Our aim was to implement a standardized US report that included secondary signs of appendicitis (SS) to facilitate accurate diagnosis of appendicitis and decrease the use of computed tomography (CT) and admissions for observation.

Methods: A multidisciplinary team implemented a quality improvement (QI) intervention in the form of a standardized US report and provided stakeholders with monthly feedback. Outcomes including report compliance, CT use, and observation admissions were compared pretemplate and posttemplate.

Introduction: Ultrasound (US) is the preferred imaging modality for evaluating appendicitis. Our purpose was to determine if including secondary signs (SS) improve diagnostic accuracy in equivocal US studies.

Methods: Retrospective review identified 825 children presenting with concern for appendicitis and with a right lower quadrant (RLQ) US.

Evaluation of patients that present to the emergency department with concerns for the diagnosis of pulmonary embolism can be difficult. Modalities including computerized tomography (CT) of the chest, pulmonary angiography, and ventilation perfusion scans can expose patients to large quantities of radiation especially if the study has to be repeated due to poor quality. This is particularly a concern in the pregnant population that has an increased incidence of pulmonary embolism and may not be able to undergo multiple radiographic studies due to fetal radiation exposure.

The molecular mechanisms by which the anti-HER2 antibodies trastuzumab and its murine equivalent 4D5 inhibit tumor growth and potentiate chemotherapy are not fully understood. Inhibition of signaling through the phosphatidylinositol 3-kinase (PI3K)-AKT pathway may be particularly important. Treatment of breast cancer cells that overexpress HER2 with trastuzumab inhibited HER2-HER3 association, decreased PDK1 activity, reduced Thr-308 and Ser-473 phosphorylation of AKT, and reduced AKT enzymatic activity.
