Cognitive Fatigue

Military service members are called upon to perform critical mission tasks 24/7 with the presence of cognitive fatigue (CF) due to sleep deprivation and circadian misalignment. These mission tasks require immense readiness, alertness and high-level performance, which cognitive fatigue can severely effect. Thus, gaining a deep understanding of cognitive fatigue (CF) is needed to help military and civilian settings deal with the potentially devastating risks associated with performance gaps from CF.

RAIVEN

This randomized, active comparator trial will compare the clinical efficacy of recombinant influenza vaccine (RIV) to standard-dose egg-based inactivated influenza vaccine (SD IIV) among adults aged 18-64 years. The primary study hypothesis is that the clinical efficacy of RIV is superior to that of SD IIV to prevent and attenuate influenza-like illness (ILI)-associated influenza virus infection.

Evaluation Study of Eye Conditions or Potential Eye Conditions

This study will allow the University of Arizona (UA) physicians and researchers the opportunity to examine people with or without eye disease, whether the diagnosis is known or not. In this study, no treatment will be offered. Participants undergo various tests and procedures to diagnose or evaluate their eye disease.

Control of irregular bleeding with Nexplanon contraceptive implants

Are you interested in trying the Nexplanon contraceptive implant? You may qualify for a research study helping to understand how vaginal bleeding patterns change on the implant and how use of oral contraceptive pills plus the implant can make those bleeding changes more manageable.

An observational study to determine the clinical characteristics in children unlikely to have a pulmonary embolism

No study has been performed to prospectively record the presenting complaints, signs, symptoms and comorbidities of children who raised the suspicion of pulmonary embolism (PE). Clinicians must extrapolate what is known about PE in adults to children. Perhaps as a result, the mortality rate of PE is the same in children as it is in adults. On the other hand, tens of thousands of low risk children and adolescents are unnecessarily exposed to increased lifetime cancer risk from ionizing radiation from CT scans done to search for PE they do not have.

2B-Alert Study

The purpose of this research study is to determine how well individualized caffeine dosing recommendations work to recover performance during continuous extended sleep loss. Results from this study will be used to help develop technology that can be deployed in the field to prevent sleep loss related declines in performance in soldiers. Work has been done to develop models that predict behavior based on previous sleep patterns, but these models have not been tested against laboratory results. This study aims to test how well one specific version of this model works.

The role of gut microbiome in epilepsy

The propose of this pilot study is to test the hypothesis that children with epilepsy have changes in gut microbiome as compared to their siblings and controls.

Our specific aims are:

1. To compare the taxonomy of gut microbiome in patients with new onset epilepsy versus siblings and controls.

2. To compare the taxonomy of gut microbiome in patients with new onset epilepsy versus chronic and refractory epilepsy.

Tissue Acquisition and Repository for Gastrointestinal and Hepatic Systems (TARGHETS)

The TARGHETS biorepository works with various gastrointestinal clinical trials and research studies within Arizona. The primary focus is to discover more effective treatments as well as diagnostics for gastrointestinal diseases. We approach a variety of donors, including normal or healthy volunteers, for consent and collection of biospecimens (urine, stool, saliva, blood, and gastrointestinal tissue) from the Banner Medical Center facilities (Main, South, and North campuses). Specimens are then aliquoted and stored for current and future research.
