Disruption of circadian rhythms is commonly reported in individuals with Alzheimer's disease (AD). Neurons in the primary circadian pacemaker, the suprachiasmatic nucleus (SCN), exhibit daily rhythms in spontaneous neuronal activity which are important for maintaining circadian behavioral rhythms. Disruption of SCN neuronal activity has been reported in animal models of other neurodegenerative disorders; however, the effect of AD on SCN neurophysiology remains unknown. In this study we examined circadian behavioral and electrophysiological changes in a mouse model of AD, using male mice from the Tg-SwDI line which expresses human amyloid precursor protein with the familial Swedish (K670N/M671L), Dutch (E693Q), Iowa (D694N) mutations...

Growing populations and industrialized agriculture practices have eradicated much of the United States wetlands along river floodplains. One program available for the restoration of floodplains is the Conservation Reserve Program (CRP). The current research explores the effects CRP land change has on flooding zones, utilizing Flood Modeller and HEC-RAS. Flood Modeller is proven a viable tool for flood modeling within the United States when compared to HEC-RAS. Application of the software is used in the Nodaway River system located in the western halves of Iowa and Missouri to model effects of introducing new forest areas within the region...

Rates of short interval pregnancies resulting in unintended pregnancies remain high in the United States and contribute to adverse reproductive health outcomes. Long-acting reversible contraception (LARC) methods have annual failure rates of less than 1% compared with 9% for oral contraceptive pills, and are an effective strategy to reduce unintended pregnancies. To increase access to LARCs in the immediate postpartum period, several State Medicaid programs, including those in Iowa (IA) and Louisiana (LA), recently established reimbursement policies to remove the barriers to reimbursement of immediate postpartum LARC insertion...

This study examined the impact of neighborhood racial discrimination on the development of major depressive disorder (MDD) in a sample of African American women. Participants were 499 women from Georgia and Iowa with no history of MDD who were followed for 9 to 11 years. Several neighborhood characteristics (community social disorder, community cohesion, and community racism) and individual characteristics (negative life events, financial strain, personal outlook, religious involvement, relationship quality, negative affectivity, and individual experiences of racism) were employed as predictors of whether or not the women met criteria for MDD during this period of time...

INTRODUCTION: Hydralazine is an antihypertensive medication that has been associated with drug-induced lupus erythematosus (DIL) as well as ANCA-associated vasculitis (AAV). Although rare, early diagnosis is critical since drug cessation is the mainstay of therapy. This retrospective study aims to characterize the clinical, laboratory, and histopathologic features of this disease. METHODS: Once approval was obtained from the Institutional Review Board at the University of Iowa, all patients carrying a diagnosis of vasculitis (ICD9 code: 447...

Objective: To evaluate the impact of Iowa's prescription monitoring program (PMP), implemented in 2009, on opioid pain reliever (OPR) prescribing patterns. Methods: We conducted interrupted time series analyses using 2003-2014 health insurance claims from a private health insurer in Iowa. OPR prescriptions for all beneficiaries were included. Another data set included only OPR prescription for new opioid users required to have six months of insurance coverage. We evaluate four OPR prescribing patterns: 1) average daily dosage in morphine milligrams equivalents (MME), 2) MME per prescription, 3) average days' supply per prescription, and 4) prescription rate per 1,000 insured person-years...

OBJECTIVE: Acute limb ischemia (ALI) in a pediatric patient is a rare condition but may result in lifelong disability. A paucity of evidence exists to derive treatment guidelines; some surgeons advocate conservative management over invasive measures. The purpose of this study was to evaluate the role of surgical revascularization in the pediatric population and outcomes of conservative vs surgical management. METHODS: The Healthcare Cost and Utilization Project State Inpatient Database (California, Iowa, and New York) between 2007 and 2013 was queried using International Classification of Diseases, Ninth Revision codes...

Veterinary diagnostic laboratories (VDLs) play a significant role in the prevention and mitigation of endemic animal diseases and serve an important role in surveillance of, and the response to, outbreaks of transboundary and emerging animal diseases. They also allow for business continuity in livestock operations and help improve human health. Despite these critical societal roles, there is no academic literature on the economic impact of VDLs. We present a case study on the economic impact of the Iowa State University Veterinary Diagnostic Laboratory (ISUVDL)...

This review summarizes evidence developed at the University of Iowa concerning the management and outcomes of developmental dysplasia of the hip beginning with the observations and analyses of Dr Arthur Steindler in the early 1900s. The strong evidence-based practice tradition established by Steindler 100 years ago continues as we critically evaluate our procedures and patient outcomes, only altering approaches when warranted by strong personal and research evidence. Our practice continues to be conservative in that we strive to produce the best environment possible for the hip to develop on its own and operate only when less invasive methods have failed...

BACKGROUND: Patients with follicular lymphoma have heterogeneous outcomes. Predictor models to distinguish, at diagnosis, between patients at high and low risk of progression are needed. The objective of this study was to use gene-expression profiling data to build and validate a predictive model of outcome for patients treated in the rituximab era. METHODS: A training set of fresh-frozen tumour biopsies was prospectively obtained from 160 untreated patients with high-tumour-burden follicular lymphoma enrolled in the phase 3 randomised PRIMA trial, in which rituximab maintenance was evaluated after rituximab plus chemotherapy induction (median follow-up 6·6 years [IQR 6·0-7·0])...
