Iowa Paid Clinical Trials

The purpose of this study is to evaluate the safety and efficacy of OMS721 in patients with IgA nephropathy. The study will assess proteinuria by 24-hour urine protein excretion (UPE) in g/day at 36 weeks from beginning of treatment. Read Less

Recent adolescent-based research shows that inference making improves across grades 6-12, uniquely accounts for variance in sentence- and passage-level comprehension, and that individual differences in inference making relate in a principled way to variations in reading comprehension for readers of all abilities (Barth et al., 2015; Barnes et al., 2015). These findings suggest that comprehension requires inference making and that comprehension fails when readers do not possess relevant knowledge (i.e., availability) or slowly retrieve (i.e., accessibility) and integrate knowledge from text or semantic memory during reading (Kendeou, 2015). To date, only one study has examined the effects of knowledge availability and accessibility on inference making among adolescents. To extend this limited body of research, this project will conduct two experimental studies designed to examine (a) the extent to which knowledge-base availability and accessibility relates to the accuracy and rate of constructing inferences using that knowledge (Aim 1) and (b) the extent to which retrieval practice (i.e., spaced practice testing) increases knowledge availability and accessibility and improves the accuracy and rate of forming inferences using that knowledge-base among middle grade readers (Aim 2). In addition, this project will integrate investigative research into an undergraduate Honors Research Program by developing an investigative laboratory component that engages undergraduates in conducting applied research (Aim 3). The research design uses 558 students in grades 5-8. To address Aim 1, mixed effects explanatory item response models will fit to the trial-by-trial reading accuracy and speed data. Repeated measures analysis of variance models will address Aim 2 with analysis of variance models used for Aim 3. The expected outcomes of the proposed research include (a) understanding how knowledge availability and accessibility relate to inference making among adolescent readers; (b) understanding the sources of inference making difficulty; and (c) methods for improving knowledge availability and accessibility and inference making to broadly implement in secondary grade classrooms.

This is an observational, multicenter study to determine the prevalence of Cerebrotendinous Xanthomatosis (CTX) in patient populations diagnosed with early-onset idiopathic bilateral cataracts. Patients who are potentially eligible for study participation will be identified through a chart review of patients who were seen at each study site prior to that site's initiation, or by entering care at the site while the site is participating in the trial.

The purpose of the study is to evaluate the hypothesis that patients receiving remote ischemic conditioning using the autoRIC device show statistically significant reduction in the prevalence of ischemia-reperfusion injury to the myocardium as compared to patients in the autoRIC Sham device arm (within 12-24 hours post non-emergent PCI with stent implantation).

In parturients undergoing Cesarean section under spinal anesthesia, co-loading of 1 liter of crystalloids, with placing the spinal, along with administering a phenylephrine infusion and glycopyrrolate, enables placing a spinal with minimal perioperative nausea and vomiting and good intra and post-operative pain relief.

Colorectal cancer is a preventable and/or a treatable cancer, but at least 43% of the United States population is not up-to-date with screening. Although 90% of colorectal cancer screening is done using colonoscopy, most other countries use fecal immunochemical tests, reserving colonoscopy for those with a positive fecal immunochemical test. This project will provide the foundation for a paradigm shift for colorectal cancer screening in the United States by identifying how well 5 different FITs work for detecting screening relevant neoplasia, thus reducing morbidity and mortality for colorectal cancer.

This study will assess whether an implantable defibrillator will increase the likelihood of survival in patients who have had a heart attack in the prior 5 years, have abnormal test results from a 24 hour heart monitor, and who have low normal heart function. Read Less
