Scoliosis is a three-dimensional deformity affecting the orientation and position of the spine. Locally, the shape of the vertebra is also affected. The most common form is adolescent idiopathic scoliosis (AIS) with a prevalence of 1-3% affecting primarily young adolescent females. AIS can either be treated using a brace and in some cases necessitate surgical correction to prevent progressive deformity. Risk factors for progression include female gender, curve magnitude and location, skeletal maturity and growth velocity. However, these risk factors have been shown to be inconsistent in predicting curve progression. Over the past 6 years, the investigators have developed a predictive model of the final Cobb angle in AIS based on 3D spinal parameters. This analysis was based on a prospective cohort of 195 patients that were enrolled upon their initial visit and followed until maturity. This predictive model has a determination coefficient of 0.702. The proposed new study aims at refining and testing the external validity of this model in a larger cohort. The next step towards using the new model in the clinical setting is to redesign the model and to externally validate the model by measuring the agreement between the new method and the traditional Cobb angle at maturity in a larger multicenter study. The objective of this study is to characterize the risk of scoliosis progression based on local three-dimensional vertebral and pelvic measurements present on initial evaluation. Three-dimensional reconstructions will be derived from stereo-radiographs acquired with a new biplanar low-dose radiographic system installed in all 8 clinical sites (EOS system, EOS-Imaging, Paris). These calibrated radiographs will then be used to reconstruct the vertebrae and intervertebral disks at each level as well as the geometry of the pelvis. A series of local and regional parameters will then be calculated from these 3D reconstructions. Correlation analysis will help determine if intervertebral disk wedging, vertebral wedging, transverse plane rotation or pelvic geometry can be used as early predictors of curve progression in AIS. Identifying a new 3D measure of scoliosis associated with rapid curve progression could help predict which curves need early treatment to prevent further progression. The ultimate goal of this research project will be to validate this new predictive model and finally transfer this new predictive tool in the hands of clinicians treating AIS. Read Less

Develop an app-based nationwide study of individuals who routinely use a smartwatch or other wearable activity tracker to determine if individualized tracking of changes in heart rate, activity and sleep can provide an early indication of influenza-like illnesses (ILI) and possibly other viral infections.

Gender diverse individuals who use gender-affirming testosterone therapy (GATT) to reduce gender dysphoria may also use progestins for contraception and to manage or suppress uterine bleeding. Research is limited, however, regarding expected bleeding patterns for individuals who choose to initiate GATT concurrently with a progestin. Clinicians who prescribe GATT do not have sufficient data to adequately counsel patients on side effects of concurrent progestin use and therefore extrapolate from studies conducted in cisgender women. This study is a prospective cohort study evaluating bleeding patterns and satisfaction among patients initiating GATT with or without concurrent initiation of a progestin contraceptive. The results from this study will enable clinicians to more accurately counsel patients using GATT on how the use of a progestin might affect their bleeding and whether this differs by progestin method.

This is a prospective, observational, multi-center cohort study of pediatric cardiac arrests. The purpose of the study is to determine the association between chest compression mechanics (rate, depth, flow fraction, compression release) and patient outcomes. In addition, the investigators will determine the association of post cardiac arrest care with patient outcomes. Read Less

The proposed project aims to integrate team-based implementation strategies with an established school-based intervention for children with ADHD, the Collaborative Life Skills Program (CLS), to enhance its implementation and optimize its effectiveness. The investigators will tailor three empirically-supported team development interventions, Team Charters, Team Communication Training (Student Handoff Protocols), and Team Performance Monitoring, and integrate them into a team-enhanced CLS implementation protocol (CLS-T). Team Charters are a written document developed collaboratively by the team at the outset of their work together outlining expectations, goals, roles and responsibilities, and relevant policies and procedures for team collaborative operations. Research shows that Team Charters strengthen affective emergent states, such as trust and cohesion among team members, as well as cognitive emergent states, such as shared mental models. They also strengthen team processes, such as goal specification, communication, and coordination to optimize team effectiveness. Handoff protocols are widely used interventions for ensuring continuity in patient care and minimizing errors in medical settings. They have also been found to improve affective (e.g., trust, cohesion) and cognitive (e.g., shared mental models, situation awareness) emergent states among team members, enhancing team communication and coordination. Finally, Team Performance Monitoring provides feedback to teams that can motivate performance, provide opportunities for adaptation in the event of challenges, and prompt communication among team members. The investigators will conduct a Hybrid Type III cluster randomized trial in 24 schools in two large urban school districts, to evaluate whether CLS-T implementation results in improved implementation outcomes and child outcomes in comparison to standard CLS implementation.

ARGONAUT is a longitudinal, prospective, observational study that will enroll up to 5,000 advanced-stage cancer patients of diverse racial backgrounds to collect data used to develop precision microbiome medicines and for the identification of clinically actionable cancer-specific biomarkers to guide therapeutic decisions. Four types of solid tumor cancers will be profiled including non-small cell lung cancer (NSCLC), triple negative breast cancer (TNBC), colorectal cancer (CRC) and pancreatic cancer. Healthy control subjects without a cancer diagnosis will also be studied, comprised of individuals at high risk for CRC and healthy individuals at low risk for CRC. Risk assessment will be based on family history or past neoplastic findings during CRC screening. Data collected from this study will be used to develop the most effective new therapies, via microbiome optimization, all to the benefit of patients and the physicians treating them. Stool and blood samples will be collected longitudinally and analyzed to determine the impact of gut microbiome composition and function on the immune system and efficacy of the treatment. Currently enrolling the CRC, high risk, and low risk cohorts. Subjects who meet the entry criteria will provide up to 5 samples each of blood and stool over a 2-year period. Approximately 10%-20% of the subjects will provide colon tissue samples, either from research biopsies during Standard of Care (SOC) screening colonoscopy or retained surgical tissue from colectomy. Electronic health records will be obtained at various times for up to 8 years, to collect tumor imaging results and any other updated medical data, with no additional samples collected. In select cases, stool and blood samples will be collected beyond 2 years. Read Less

Aspirin-Exacerbated Respiratory Disease (AERD), although uncommon in the general population, is an important phenotype of severe asthma and nasal polyposis where it occurs in 15% of severe asthmatics, and up to 30% of those with nasal polyposis. An important therapy for AERD is aspirin therapy after desensitization (ADAT). This is an inexpensive and proven therapy to improve the burden of sinus disease in AERD. Aspirin desensitization is the mechanism by which tolerance is induced in AERD patients. This is a 1-2 day outpatient procedure whereby increasing doses of aspirin are administered and the patients invariably experience some degree of hypersensitivity reactions. It is important to understand the effect of medications on the aspirin desensitization. It is known that the leukotriene modifier medications decrease the severity of the reactions in AERD. Other treatments such as antihistamines and the biologic agent omalizumab might have an effect on either blocking or blunting reactivity in AERD during desensitization. Dupilumab is a new respiratory biologic approved for atopic dermatitis, eosinophilic asthma and nasal polyposis. As such, it is well situated to be used for many AERD patients whose disease cannot be well controlled. The effect of dupilumab on the aspirin desensitization process and reaction is unknown and is the topic of this investigation. The primary objective is to determine the effect of dupilumab on reactions during aspirin challenge/desensitization. Read Less

The goal of this observational study is to learn about the utility of biopatches predicting 30-day readmissions in patients discharged from the hospital with sepsis. The main question\[s\] it aims to answer are: • Does the application of a biopatch provide data that can improve prediction of an unplanned 30-day readmission following a hospitalization for sepsis. Participants will be asked to wear a biopatch on their chest for 30-days following hospital discharge or until readmission to the hospital. Read Less
