The goal of this clinical trial is to determine if adding avocados to the diet of impacts cognition in 70 older adults, age 65-85, without dementia. We will test for change in functional MRI, cognitive performance, and brain blood flow. Intervention group participants will be asked to consume 1 avocado per day for 12 weeks. Participants in the control group will be asked to continue their normal intake for 12 weeks. Throughout the study, participants will be asked to perform cognitive tests, MRI, blood tests, and questionnaires. Read Less

Many neighborhoods in Chicago experience daily exposure to stressors including economic inopportunity and violent crime in public spaces. There is mounting evidence that chronic psychosocial stress can facilitate carcinogenesis by modulating the gut microbiome and immune system. The proposed research aims to study the practice of mindfulness to mitigate CPS and reduce colorectal cancer risk factors among Black American women at elevated risk. Read Less

This study is a double-blind, randomized controlled trial comparing the effectiveness of oral acetaminophen, diclofenac, and tramadol in reducing the consumption of narcotic doses (primary outcome) and minimizing patients' exposure to narcotics (secondary outcome) following an ultrasound-guided percutaneous needle tenotomy procedure on the lateral elbow.

In the critically ill population, fluid administration in an unstable patient is perhaps the most common intervention that is performed. Uncorrected hypovolemia with inappropriate vasopressors lead to organ hypoperfusion where as overzealous fluid administration especially in ARDS (Adult respiratory distress syndrome) can increase mortality. It has been estimated that only 50% of hemodynamically unstable critically ill patients are volume responsive, hence dynamic assessment of preload responsiveness has been proposed to better identify those individuals who would benefit from fluid bolus.

This is a single-centre prospective observational study aimed to determine if Pocc (occlusion pressure at 100 msec), TCe ( Expiratory time constant ), Mechanical Stress power, Ventilatory ratio and C20/Cdyn would predict outcomes in patients with moderately severe ARDS (Acute respiratory distress syndrome), who are on mechanical ventilation Read Less

Zavegepant (Zavzpret) is approved for the acute treatment of migraine with or without aura in the US. The purpose of this study is to investigate the effectiveness and tolerability of zavegepant for the acute treatment of migraine attacks amongst participants who are using calcitonin gene-related peptide (CGRP) migraine preventive treatments.

This project will use intracranial recordings and stimulation of the human brain to understand the unique contributions of the posterior cingulate cortex (PCC) to episodic memory behavior. The goal is to test how distinct subregions of the PCC differentially contribute to memory-based decisions (e.g., have I seen this picture before?). The ability to perform invasive studies of the human brain is through routine clinical monitoring of brain activity which occurs during the neurosurgical treatment of epilepsy. However, this project only focuses on the basic science of PCC and memory behavior. Specifically, the investigators will use single-0cell and population measures of brain activity to test a new theory of PCC function which focuses on the executive processes needed to support memory retrieval and memory-based decisions. By studying the PCC, a convergence zone of memory and executive brain systems, progress can be made in elucidating how the failure to successfully leverage past experiences in daily behavior can occur as a common symptom of both neurodegenerative disease (e.g., Alzheimer's disease) and multiple psychiatric conditions (e.g., schizophrenia) implicating PCC dysfunction.

This project addresses the significant challenge of providing evidence-based non-pharmacologic pain management to rural-dwelling Veterans in the VA healthcare system who have chronic pain. For this preparatory phase (UG3) the investigators will conduct a pilot study of 40 rural VA patients with chronic pain to assess the feasibility of delivering RAMP (experimental intervention for the UH3 trial) in terms of recruitment and engagement, intervention fidelity and adherence, data collection, and other key metrics.

The purpose of this study is to observe predictors of pituitary tumor recurrence and markers of persistent disease activity in patients harboring pituitary mass lesions of all types. Read Less

The purpose of this study is to prospectively collect specimens from pediatric patients with diffuse intrinsic pontine glioma or brainstem glioma, either during therapy or at autopsy, in order to characterize the molecular abnormalities of this tumor. Read Less
