This project will (a) examine the relationship between knowledge retrieval and inferencing; (b) determine the effectiveness of an intervention that improves knowledge retrieval and inferencing among struggling readers; and (c) expand research opportunities for undergraduates. The research design uses 316 struggling readers in grades 4-6 of diverse backgrounds. The effects of knowledge retrieval (accuracy and speed) on inferencing will be modeled without dichotomizing the distribution. Linear mixed effect models will be fit to determine whether reader characteristics make unique contributions to inferencing across the posttest and follow-up data collection time points. First, several structural models will be considered as students may be nested in teachers, schools, and tutors. Unconditional models will estimate the intraclass correlation for each level of the study design. If significant interclass correlations emerge, multilevel models will be fit to evaluate the effectiveness of the intervention while controlling for covariates such as pre-test performance on inference-related measures and child-attributes such as English learner status. The primary analysis plan assumes an intent-to-treat model in which the efficacy of two intact conditions will be tested. Effect sizes will be estimated to report the magnitude of difference between the two conditions. Expected outcomes include (a) the identification of a method that effectively facilitates knowledge retrieval and the application of relevant knowledge to form inferences among elementary struggling readers from diverse backgrounds; (b) the validation of an intervention that teaches struggling readers how to activate, retrieve, and interweave relevant knowledge with information in the text and accurately form inferences while reading that can be broadly implemented in general education classrooms; and (c) expansion of undergraduate research opportunities, particularly among students from diverse backgrounds who have been historically underserved.

This research aims to collect comprehensive data on the clinical trial experience of OCD patients. Its goal is to identify the factors that limit patients' ability to join or complete a trial successfully. Clinical trial participation often favors specific demographic groups, and limited research exists on the impact of trial attributes on participation. Therefore, this study aims to analyze data from various demographic groups and identify any recurring trends that could provide valuable insights for future OCD patients.

This phase II trial studies the effect of the combination of ramucirumab and trifluridine/tipiracil or paclitaxel in treating patients with previously treated gastric or gastroesophageal junction cancer that has spread to other places in the body (advanced). Ramucirumab may damage tumor cells by targeting new blood vessel formation. Trifluridine/tipiracil is a chemotherapy pill and that may damage tumor cells by damaging their deoxyribonucleic acid (DNA). Paclitaxel may block cell growth by stopping cell division which may kill tumor cells. Giving ramucirumab and trifluridine/tipiracil will not be worse than ramucirumab and paclitaxel in treating gastric or gastroesophageal junction cancer.

Despite advances in HIV diagnostics, care and prevention strategies, infection rates among adolescent and young adult sexual and gender minorities (SGM) continue to rise in the United States (US). There is an urgent need to describe the epidemiology and trajectories of HIV acquisition in this population and to offer age and culturally appropriate scalable prevention interventions to those at highest risk of infection in the US. This project will engage and retain young SGM in an innovative longitudinal cohort, enroll participants in a dynamic established digital health retention platform (HMP; HealthMPowerment), monitor HIV risk and prevention behaviors and explore the socioecological factors that influence the use of new HIV prevention technologies (UG3 phase), while also allowing targeted testing of novel digital health interventions (UH3 phase). In Aim 1, the investigators will enroll and retain a large (n=6000; 3000/year), diverse cohort of sexually active, SGM adolescents and young adults, ages 13-34, using innovative digital recruitment, engagement and retention strategies. Over the course of the study, the investigators will longitudinally characterize the sexual behavior, HIV transmission risk, and PrEP uptake trajectories of SGM youth utilizing epidemiological trajectory analyses to identify the most effective points of intervention (Aim 2). This study will capitalize upon productive existing partnerships and digital health expertise to articulate the drivers of the ongoing HIV epidemic among the most vulnerable populations in the US in order to identify the most effective, expeditious and scalable strategies to address this ongoing public health crisis.

Aortic stenosis (AS) is a serious and common condition that affects 2-3% of the population >65 years of age in Western countries. It is also responsible for extraordinarily high healthcare expenditures, estimated to be over $6 billion annually,2 in part because the primary treatment for severe AS is aortic valve replacement (AVR) which is resource-intensive. Valve abnormalities are frequently recognized before AS becomes severe, or before there is need for guideline-directed procedural intervention, thereby providing an opportunity for pharmacologic intervention to slow disease progression. Yet, all attempts to prevent AS progression in those with degenerative non-congenital forms of disease have failed. The only non-procedural intervention that benefits patients with moderate or greater AS is the aggressive treatment of hypertension, which reduces net left ventricular (LV) afterload (valvulo-arterial impedance [Zva]) and can slow secondary LV remodeling. The overall goal of this proposal is to integrate advanced imaging and vascular biology to study how von Willebrand factor (VWF) and platelet adhesion promote AS progression through many parallel pathways, thereby representing a potential therapeutic target. We are hypothesizing that blood markers of abnormal VWF proteolysis and platelet-derived factors, and abnormal valve shear patterns which can be detected by advanced analysis of spectral Doppler on echocardiography are predictors for progressive AS.

The objective is to better identify suspicious breast lesions that need to be biopsied for malignancy in women currently recommended for biopsy. The long-term goal is to reduce unnecessary biopsies and increase biopsy yield. To do this, the investigators have developed an innovative way to use FDA-approved breast imaging protocols to acquire multispectral images to measure the composition of suspicious breast lesions. The central hypothesis is that breast tissue composition in combination with analysis of morphological and textural tissue characteristics on digital breast tomosynthesis (DBT) imaging will yield significantly higher breast cancer specificity than conventional interpretation of DBT alone.
