BACKGROUND It is unclear whether procalcitonin is an accurate predictor of bacterial infections in patients with renal impairment, although it is used as a biomarker for early diagnosis of sepsis. We determined the sensitivity, specificity, positive and negative predictive values, accuracy and best predictive value of procalcitonin for predicting bacterial(More)
IMPORTANCE Laparoscopic ventral hernia repair (LVHR) using mesh is a well-established intervention for ventral hernia, but pain control can be challenging. OBJECTIVE To determine whether instillation of a long-acting local anesthetic between the mesh and the peritoneum after LVHR reduces pain or narcotic requirements. DESIGN, SETTING, AND PARTICIPANTS A(More)
OBJECTIVE. For full-field digital mammography (FFDM), federal regulations prohibit lossy data compression for primary reading and archiving, unlike all other medical images, where reading physicians can apply their professional judgment in implementing lossy compression. Faster image transfer, lower costs, and greater access to expert mammographers would(More)
Patients on anticoagulation are at increased risk for intracranial hemorrhage (ICH) after trauma. This is important for geriatric trauma patients, who are increasing in number, frequently fall, and often take anticoagulants. This study sought to evaluate whether prehospital use of dabigatran, a newer anticoagulant, is associated with outcome differences in(More)
Background : Hepatitis C (HCV) direct acting antiviral agents (DAAs) are safe, effective, and tolerable. Most contraindications to interferon-based treatment are no long applicable. The aims of this study were to understand the predictors of approval to drug accessibility. Methods : We studied all consecutive patients with HCV prescribed DAAs between(More)
Antiplatelet and anticoagulant medication increases the risk of intracranial hemorrhage (ICH) after a fall in geriatric patients. We sought to determine whether there were differences in ICH rates and outcomes based on type of anticoagulant or antiplatelet agent after a ground-level fall (GLF). Our institutional trauma registry was used to identify patients(More)
BACKGROUND Small bowel obstruction (SBO) is commonly encountered by surgeons and has traditionally been handled via an open approach, especially when small bowel resection (SBR) is indicated, although recent series have shown improved outcomes with a laparoscopic approach. In this retrospective study, we sought to evaluate outcomes and identify risk factors(More)
AIM To compare age-related morbidity and mortality after transjugular intrahepatic portosystemic shunts (TIPS). METHODS We performed a retrospective chart review of patients who underwent TIPS at the University of California Los Angeles Medical Center between 2008 to 2014. Elderly patients (65 y and older) were matched with nonelderly patients (controls,(More)
BACKGROUND AND AIMS All-oral interferon-free antivirals are highly effective in treating recurrent hepatitis C (HCV) infection in liver transplant (LT) recipients. The aim of the study was to assess immunosuppression needs after achieving a sustained viral response (SVR). METHODS We compared immunosuppression needs before and after achieving a SVR in(More)
