Ovarian transplantation was first conducted at Utah State University in 1963. In more recent work, heterochronic transplantation of mammalian ovaries is being used to investigate the health-protective effects of young ovaries in young females. The current procedures employ an orthotopic transplantation method, where allogenic ovaries are transplanted back to their original position in the ovarian bursa. This is in contrast to the more commonly used heterotopic transplantation of ovaries/ovarian tissue subcutaneously or under the kidney capsule...

PURPOSE: To study the role of individual semen parameters on the offspring birth weight and body mass index (BMI) from a population of men evaluated in an assisted reproduction technology (ART) clinic compared to fertile controls. METHODS: We performed a retrospective study using a cohort with fertile, age-matched controls of men evaluated with semen analysis at the University of Utah Andrology Clinic from 1996 to 2011 and Intermountain Healthcare from 2002 to 2011...

PURPOSE: To evaluate intraocular lens (IOL) power, modulation transfer function (MTF), light transmission, and light scattering of a blue light-filtering IOL before and after power adjustment by a femtosecond laser obtained through increased hydrophilicity of targeted areas within the optic, creating the ability to build a refractive-index-shaping lens within an existing IOL. SETTING: John A. Moran Eye Center, University of Utah, Salt Lake City, Utah, USA. DESIGN: Experimental study...

Neutrophil-to-lymphocyte ratio is a strong predictor for overall survival and disease free survival in many cancers. Our study is the first investigation aiming to determine the predictive value of neutrophil-to-lymphocyte ratio on prognosis of patients with stage III melanoma. This retrospective study utilized a cohort of 107 patients with stage III melanoma treated at Huntsman Cancer Institute, University of Utah, from May 2002 to March 2016. The optimal cutoff of neutrophil-to-lymphocyte ratio was determined by the significance of log-rank tests...

Editor's note: On July 26, 2017, Alex Wubbels, the charge nurse on the burn unit at the University of Utah Hospital in Salt Lake City, was arrested for refusing to allow a police officer to draw blood from an unconscious patient in her care. Her arrest, during which she was forcefully placed in handcuffs and dragged out of the hospital, was documented on body camera video and drew national attention. We asked our ethical and legal contributing editors to provide some insight on the issues of this case.

BACKGROUND: Adding value in a university-based academic health care system provides unique challenges when compared to other health care delivery models. Herein, we describe our experience in adding value to joint arthroplasty care at the University of Utah, where the concept of value-based health care reform has become an embraced and driving force. METHODS: To improve the value, new resources were needed for care redesign, physician leadership, and engagement in alternative payment models...

OBJECTIVE: To determine the comparative diagnostic characteristics of neuropathy measures in an obese population. METHODS: We recruited obese participants from the University of Michigan's Weight Management Program. Receiver operative characteristic analysis determined the area under the curve (AUC) of neuropathy measures for distal symmetric polyneuropathy (DSP), small fiber neuropathy (SFN), and cardiovascular autonomic neuropathy (CAN). The best test combinations were determined using stepwise and Score subset selection models...

BACKGROUND: Muscle mass deficits endure after hip fracture. Strategies to improve muscle quality may improve mobility and physical function. It is unknown whether training after usual care yields muscle quality gains after hip fracture. OBJECTIVES: To determine whether muscle quality improves after hip fracture with high-intensity resistance training and protein supplementation. DESIGN: Case series. SETTING: University of Utah Skeletal Muscle Exercise Research Facility...

INTRODUCTION: Annually, residents are expected to take an in-service examination to gauge their understanding of plastic surgery knowledge and prepare them for the American Board of Plastic Surgery written examination. In addition, in-service score are now being used as an assessment tool for fellowship applicants. Because of the breadth of Plastic Surgery material, it is difficult to prepare a resident for such a comprehensive examination. At the University of Utah, a weekly conference was instituted to help prepare residents for the in-service and board examination with the goal of improving scores...

BACKGROUND AND PURPOSE: Up to 30% of acute stroke evaluations are deemed stroke mimics, and these are common in telestroke as well. We recently published a risk prediction score for use during telestroke encounters to differentiate stroke mimics from ischemic cerebrovascular disease derived and validated in the Partners TeleStroke Network. Using data from 3 distinct US and European telestroke networks, we sought to externally validate the TeleStroke Mimic (TM) score in a broader population...

OBJECTIVE: The objective of this communication is to provide an evolutionary description of an attempt to replicate the success of the Rampahl Cardiac Simulator using perfused abdominal organ blocks the way that the Rampahl Simulator uses ex vivo porcine hearts. DESIGN: This descriptive paper makes no attempt to prove the effectiveness of the described educational tool, but rather, outlines the successes and failures in development. The proven value of a perfused organ teaching tool, as the Rampahl Simulator, suggests that others can build upon the work described in this paper so that, in the future, perfused abdominal organs will be available to students of general surgery as a routine part of their pre-operative preparation...

Background: Arterial puncture for blood gas analysis is a common procedure in hospitals. The aim of the study is to determine if standardizing technique elements of the arterial puncture process could improve the success rate of technicians through the full scope of an academic medical center. Methods: The study is conducted by the Blood Gas Laboratory at University of Utah Health's main campus. During the baseline period, technicians tallied whether arterial puncture attempts were successful or unsuccessful from December 2014 through February 2015...

Because of a previous association of pseudotumor cerebri (PTC) with levonorgestrel, we wished to evaluate the use of levonorgestrel-eluting intrauterine devices ("levonorgestrel intrauterine systems", LNG-IUS) in our University of Utah and Rigshospitalet PTC patients. In our retrospective series, PTC prevalence was approximately 0.18% and 0.15% in the LNG-IUS population versus 0.02% and 0.04% in the non-LNG-IUS population (Utah and Rigshospitalet, respectively), with no significant differences in PTC signs and symptoms among the two groups...

PURPOSE: To assess the effect of varying levels of torsional power on phacoemulsification efficiency using an active-fluidics phacoemulsification platform with a 0.7 mm Sonata tip. SETTING: John A. Moran Eye Center Laboratories, University of Utah, Salt Lake City, Utah, USA. DESIGN: Experimental study. METHODS: A 0.7 mm tip was used to emulsify 2.0 mm porcine lenses that had been hardened in formalin. The torsional power was varied from 10% to 100% at intervals of 10%, and efficiency and chatter were recorded...

INTRODUCTION: We aimed to describe the strategies of surgical revision for catheterizable channel obstruction and their outcomes, including restenosis and new channel incontinence. METHODS: We retrospectively queried the charts of adults who underwent catheterizable channel revision or replacement from 2000-2014 for stomal stenosis, channel obstruction, or difficulty with catheterization at the Universities of Minnesota, Michigan, and Utah. The primary endpoint was channel patency as measured by freedom from repeat surgical intervention...
