Short gamete co-incubation (SGCO) consists in decreasing the duration of contact between oocytes and sperm from the standard overnight insemination (SOI) toward 2 hours. However, the effectiveness of this technique to improve in vitro fertilization and embryo transfer (IVF-ET) outcomes remains controversial. Our study was designed to evaluate the efficiency of SGCO in a poor prognosis population with a history of fragmented embryos defined by the presence of at least 50% of the embryos with more than 25% of cytoplasmic fragments...

Given prior studies that suggest the use of angiotensin system inhibitors (ASIs) is associated with prolonged overall survival (OS) in glioblastoma (GBM) patients, we evaluated the effect of ASIs in glioma patients receiving chemotherapy and/or bevacizumab (BEV). Using retrospective IRB-approved electronic chart review of newly diagnosed WHO grade 2-4 glioma patients from the Kaiser Permanente Tumor Registry of Northern California, we evaluated the impact of ASIs on OS by Cox proportional hazard model analysis for subgroups who received cytotoxic therapy, cytotoxic therapy with BEV, or BEV alone, as well as those with recurrent GBM (rGBM)...

PURPOSE: The practice of radiology often includes routine communication of diagnostic test results directly to patients in breast imaging and interventional radiology. There is increasing interest in expanding direct communication throughout radiology. Though these conversations can substantially affect patient well-being, there is limited evidence indicating that radiology residents are specifically taught methods to effectively convey imaging results to patients. Our purpose is to evaluate resident experience communicating imaging results to patients...

AGC(®) (Automatic Gas Control) is the FLOW-i's automated low flow tool (Maquet, Solna, Sweden) that target controls the inspired O2 (FIO2) and end-expired desflurane concentration (FAdes) while (by design) exponentially decreasing fresh gas flow (FGF) during wash-in to a maintenance default FGF of 300 mL min(-1). It also offers a choice of wash-in speeds for the inhaled agents. We examined AGC performance and hypothesized that the use of lower wash-in speeds and N2O both reduce desflurane usage (Vdes). After obtaining IRB approval and patient consent, 78 ASA I-II patients undergoing abdominal surgery were randomly assigned to 1 of 6 groups (n = 13 each), depending on carrier gas (O2/air or O2/N2O) and wash-in speed (AGC speed 2, 4, or 6) of desflurane, resulting in groups air/2, air/4, air/6, N2O/2, N2O/4, and N2O/6...

BACKGROUND: Identification of optimal surgical site antisepsis preparations may reduce cesarean-related surgical site infections. Two recently published investigations examined efficacy of chlorhexidine-alcohol and iodine-alcohol preparations. No previous randomized controlled trial has compared chlorhexidine-alcohol to povidone-iodine aqueous scrub and paint in reduction of cesarean-related surgical site infection. OBJECTIVE: The purpose of the study was to determine if chlorhexidine-alcohol would result in less surgical site infections than povidone-iodine when used as skin antisepsis preparation prior to cesarean delivery...

Alan R Tait, Michael E Geisser
BACKGROUND: There is currently no consensus from the relevant stakeholders regarding the operational and construct definitions of child assent for research. As such, the requirements for assent are often construed in different ways, institutionally disparate, and often conflated with those of parental consent. Development of a standardized operational definition of assent would thus be important to ensure that investigators, institutional review boards, and policy makers consider the assent process in the same way...

BACKGROUND: Correction of fixed spinal imbalance in a sagittal and/or coronal plane frequently needs a tricolumnar wedge resection when the deformity is rigid. Complications associated with deformity correction surgery are pseudoarthrosis and implant failure located along the construct. The purposes of this study were to assess comparative rates of pseudoarthrosis (implant failure) at weaker points along lumbosacral junction and level of osteotomy, estimate overall incidence of implant failure, and comparatively analyze failures at different points along the construct...

Alzheimer's disease (AD) is a common, chronic expensive debilitating neurodegenerative disease with no current treatments to prevent the physical deterioration of the brain and the consequent cognitive deficits. The current pathophysiology of Alzheimer's disease is the accumulation of neurofibrillary tangles (NFTs) of hyperphosphorylated tau protein and amyloid-beta (Aβ) plaques. Antibody therapy of Tau and Amyloid beta, vaccines and other methods to decrease Tau and or Amyloid have not been successful after considerable pharmaceutical and biotech efforts...
