Intro: It has long been established that corticosteroids have a negative impact on the human immune system’s ability to function at an optimal level. Many past studies have shown that patient’s will have higher rates of infection if they are taking chronic steroids. What has yet to be established is just how much of an increased risk patients on chronic steroids have for infection after undergoing lumbar decompression surgeries, of which there are thousands per year. We hypothesize that patients on chronic steroids will have higher rates of surgical site infections and higher rates of other infections (UTI, pneumonia, etc.) …

BACKGROUND: Questions remain about the therapeutic durability of transoral incisionless fundoplication (TIF). In this study, clinical outcomes were evaluated at 5 years post-TIF 2.0.

METHODS: A total of 63 chronic gastroesophageal reflux disease (GERD) sufferers with troublesome symptoms refractory to proton pump inhibitor (PPI) therapy, absent or ≤2 cm hiatal hernia, and abnormal esophageal acid exposure were randomized to the TIF group or PPI group. Following the 6-month evaluation, all patients in the PPI group elected for crossover to TIF; therefore, all 63 patients underwent TIF 2.0 with EsophyX

RESULTS: Of 63 patients, 60 were available at 1 year, 52 …

Introduction: To determine the impact of standardization of postoperative transitions of care to the pediatric intensive care unit on handover efficiency and the quality of healthcare data exchange.

Methods: This was a prospective, pre–post observational study after standardization of postoperative transitions in a 44-bed pediatric intensive care unit in a 313-bed tertiary care pediatric hospital from April to July 2015. Standardization was completed using a multidisciplinary handover checklist. Primary outcomes were efficiency expressed as mean handover duration and the comprehensiveness of healthcare data exchange.

Results: Forty-seven postoperative transitions were observed of which 23 were preintervention and 24 were postintervention. After …

New diagnostic catheters can be developed by delivering and acquiring light through a small fiberoptic bundle. This can provide a useful real time feedback guidance to observe tissue damage caused by thermal injury used to treat cardiac arrhythmias. Yet, little is known about the exact spectral changes caused by radiofrequency ablation (RFA) in different types of cardiac tissue. We hypothesized that the most sensitive optical ranges for characterizing thermal injury can be revealed by comparing spectral information from different areas of the heart before and after RF ablation. Freshly excised porcine hearts were used to acquire and analyze excitation emission …
