OBJECTIVE We previously showed that in asphyxiated fetal lambs the duration of hypotension correlated well with the severity of histologic damage to the brain, whereas the duration of bradycardia did not. This study compares fetal heart rate patterns with the degree of histologic damage to the brain. STUDY DESIGN Twelve chronically instrumented near-term(More)
OBJECTIVE Several non-commercial rapid urease tests have been designed with the objective of reducing the cost of Helicobacter Pylori infection diagnosis. The objective of the present prospective trial is to assess one of these tests, using the histologic evaluation for the presence of Helicobacter Pylori, as the standard reference of diagnosing this(More)
Physicians' biases for skin color and obesity may negatively affect health-care outcomes. Identification of these biases is the first step to address the problem. We randomized 128 U.S medical students into one of four animated videos of avatar physician-patient counseling sessions, varying the weight and skin color of an elderly patient avatar: white-thin,(More)
OBJECTIVES The study analyzed the phase relationship between fetal heart rate and arterial blood pressure fluctuation during sinusoidal heart rate patterns in fetal lambs. STUDY DESIGN Thirty-two fetal lambs were placed on extracorporeal membrane oxygenation after cesarean delivery at ages ranging between 113 and 133 days' gestation. Sinusoidal heart rate(More)
Virtual worlds could offer inexpensive and safe three-dimensional environments in which medical trainees can learn to identify home safety hazards. Our aim was to evaluate the feasibility, usability, and acceptability of virtual worlds for geriatric home safety assessments and to correlate performance efficiency in hazard identification with spatial(More)
OBJECTIVES To implement and pilot test our Self-Management Internet-Based Program for Older Adults with Overactive Bladder (OAB-SMIP) in a group of older adults with overactive bladder (OAB) to determine its usability and outcomes, including knowledge, self-efficacy, perception of bladder condition, and health-related quality of life. METHODS In a(More)
OBJECTIVES To evaluate the effectiveness of the hysteroscopic polypectomy in terms of the decrease of the abnormal uterine bleeding. METHODS A cross-sectional and analytical study was done with patients to whom a hysteroscopic polypectomy was done for treating the abnormal uterine bleeding, between January 2009 and December 2013. The response to the(More)
BACKGROUND Avatars and virtual worlds offer medical educators new approaches to assess learners' competency in home-safety assessments that are less time-consuming and more flexible than traditional home visits. We sought to evaluate the feasibility and acceptability of implementing an avatar-mediated, 3-dimensional (3-D) home simulation as a virtual(More)
