Loss of reading ability due to stroke, called alexia, likely affects over a million Americans at any given time and causes difficulty performing many daily life functions, such as paying bills, using email/text, reading for pleasure, and reading signs in the community. Understanding the brain and cognitive basis of alexia could improve diagnosis and treatment of this important problem. In this study, the investigators will perform a large-scale behavioral and brain imaging study of stroke survivors and typical older adults to improve our understanding of the brain and cognitive basis of reading in both of these groups. Participants will complete a battery of tests of reading, speech, language, and thinking abilities. In addition, some participants will complete an MRI. Sessions will be completed across approximately 2-6 weeks, but may be extended depending on participants' schedules and availability. Some participants will be invited to repeat these procedures once or twice in approximately 3-12 months to monitor for changes in reading abilities and MRI measurements over time.

EGFR gene mutations are some of the most commonly occurring mutations in non-small cell lung cancer. Investigators have developed a DNA instability model that estimates a risk score to assess the likelihood of an individual acquiring a cancer-linked mutation. The aim of this study is to collect blood from both those diagnosed with EGFR positive lung cancer and healthy individuals, evaluate their gene sequence surrounding the EGFR landscape and use the cancer positive and healthy sequences to validate the risk assessment model, which may one day be used to provide insight on susceptibility of getting EGFR positive lung cancer or potentially other cancer types.

In addition to chronically elevated MSNA, there is a growing recognition that hypertension in states of insulin resistance and obesity may also be attributed to an increased vascular sensitivity to MSNA (1, 2, 13, 36-38). To study this phenomenon, we quantify vascular sensitivity to MSNA using an innovative, moment-to-moment assessment of the blood pressure response following individual bursts of muscle sympathetic nerve activity (MSNA), (10, 11, 34, 37). This approach is termed 'sympathetic-vascular transduction (SVT).' We will examine the hypothesis that SVT is exaggerated in obesity and insulin resistance and is attenuated by suppression of oxidative stress. Oxidative stress is the overabundance of reactive oxygen species and is another hallmark of hypertension, obesity, and insulin resistance. Oxidative stress can be safely reduced via intravenous infusion of ascorbic acid (Vit C) (4, 28). Therefore, we will use a randomized, double-blinded, placebo-controlled approach to test the hypothesis that elevated SVT will be attenuated by suppression of oxidative stress via ascorbic acid I.V. infusion compared with saline I.V. infusion (placebo) in obese adults with insulin resistance. Our study will identify a unique mechanism that can be targeted to reduce the excessively high prevalence of hypertension and risk for CVD in obesity and insulin resistance.

Health inequalities, social isolation, and family adversity impact a child's development. Play is the context for child development in all areas. A parent's ability to support children at play while being playful contributes to their psychological adjustment. The proposed tier 1, strengths-based educational program for parents of children aged 2 to 5 years with and without disabilities combines elements of a play-based approach and tips on effective parenting to support children's development by equipping parents with knowledge and empowering them to become change agents in their children's lives.

The primary objective of this prospective study is to investigate the effects of Blood Flow Restriction (BFR) training compared to traditional low-weight resistance training on grip strength in young adults. Despite the growing interest in BFR training and its potential benefits, there is limited research specifically investigating its impact on grip strength. Understanding the effects of BFR training on grip strength could have significant implications for individuals seeking to optimize their grip performance, rehabilitation settings, and sports performance enhancement. Additionally, examining the safety and efficacy of BFR training for this specific outcome will contribute valuable insights to the scientific community.

Having spine surgery and recovery is a vulnerable period when opioid naive patients may transition into long-term use of opioids, and when previously opioid tolerant patients may be at risk to continue towards long-term opioid use and dependence. However, little is known about risk for developing opioid misuse, taking opioids differently than indicated or prescribed, and later OUD. This study addresses the question of whether behavior, cognitive features, and genomic markers can predict misuse of opioids, persistent pain and disability in individuals after spine surgery. To determine if impulsivity, inhibitory control, drug choice, and/or cognitive distortions predict opioid misuse and disability in spine surgery patients with differential gene expression. This is a prospective observational longitudinal study characterizing behavioral phenotypes in adults undergoing spine surgery using both patient-reported survey measures, cognitive testing and blood sampling. Outcome measures include correlations between impulsivity measures, opioid drug choice responses and cognitive distortion scores, and opioid misuse with spine related disability, and gene expression counts.
