The two main objectives of this study are to demonstrate safety and effectiveness of implanting the PanOptix Trifocal IOL in patients who have had previous myopic Lasik. The primary objectives to demonstrate clinical safety will be the quality of vision questionnaire (QUVID) which will demonstrate the patient's perception of halos, glares, and starbursts before and after the implantation of the trifocal IOL. The primary objective to demonstrate clinical effectiveness will be done by measuring visual outcomes at distance, intermediate, and near. In addition, the patients will also fill out the spectacle independence questionnaire (IOLSAT Questionnaire) to determine their level of glasses independence postoperatively. In addition, at the conclusion of the study the patient will also fill out a patient satisfaction survey. Read Less

We will recruit 216 subjects meeting the eligibility criteria. After completing a baseline battery session via secure video conferencing and 3-week phone survey period, adolescents will be randomly assigned to receive 1 of 3 web-based single session interventions (SSIs) at a second secure video conference session. This second session for the intervention will take place within 2-3 weeks after the phone survey period. Immediately pre- and post-SSI, adolescents will complete a limited number of self-report questionnaires to index shifts in proximal outcomes. Participants, both adult and youth, will complete additional follow-up questionnaires 3, 6, 12, 18, and 24 months post-intervention. Participants will complete the intervention, including the pre- and post- SSI questionnaires, and follow-up surveys on their own. Read Less

Severe Acute Respiratory Infection (SARI) is defined by the World Health Organization (WHO) as acute respiratory infection with a history of fever ≥38°C and cough for less than 10 days duration that requires hospital admission. SARI-PREP is a multi-center consortium funded by the CDC Foundation being assembled with the goal of providing the infrastructure to rapidly collect prospective data on clinical risks and outcomes, hospital-level stress, and biologic specimens that will aid in the rapid development of diagnostic and treatment approaches. A current example of a form of SARI to be targeted by SARI-PREP is COVID-19 the acute respiratory infectious disease caused by SARS-CoV-2 infection. COVID-19 has a broad set of manifestations and severity with a subset of affected patients developing severe disease leading to respiratory failure and other forms of organ dysfunction. As with many outbreaks of novel viral pathogens causing SARI there was no efficacious therapeutic intervention at the beginning of the COVID-19 pandemic. Furthermore, while there is emerging knowledge of clinical risks for severe COVID-19, there remains a paucity of information about the viral dynamics and host responses that might indicate a patient is at high risk for poor outcomes. The COVID-19 pandemic will be the initial target of the SARI-PREP consortium with the overall goal of developing a multi-institutional collaborative network of Acute Care Hospitals that will rapidly enroll, sample, and follow patients admitted with severe COVID-19 and to develop research protocols to rapidly determine demographic, clinical, host molecular, virologic, and institutional correlates of outcome. Overall, the information gained from this effort will help to rapidly inform and improve clinical management of epidemic/pandemic SARI patients. Read Less

Veye Lung Nodules (Aidence B.V., Amsterdam, the Netherlands) is a medical software device that is intended to assist radiologists with pulmonary nodule management on CT chest scans. This clinical trial aims to assess the clinical performance of Veye Lung nodules via a standalone performance evaluation and a reader study. Read Less

This research will test the hypothesis that immune system disequilibrium / dysfunction explains why preoperative cognitive impairment is a strong predictor of postoperative morbidity in older surgical patients. The investigators propose that cognitive impairment influences surgical morbidity because of underlying immune disequilibrium / dysfunction (risk marker) and that this shapes the immune response to surgery and defines immunological hallmarks of postoperative morbidity (disease marker). The overarching goal of this application therefore is to define and better understand the clinical immunology underlying the relationship between cognition and geriatric surgical morbidity.

Continuous glucose monitoring (CGM) is an emerging field for diabetes management. CGMs are small devices primarily placed on a patient's upper arm that allow providers and patients to individualize therapy by looking at real time glucose levels. While the accuracy of these devices is extensively researched, there are no large-scale studies evaluating the differences between left and right arm glucose readings in the diabetic population. Additionally cinnamon and aloe vera are supplements commonly used by diabetic patients to help improve glycemic control. However, there remains a shortage of studies researching the effects of cinnamon and aloe vera on diabetic patients' glycemic control. The purpose of this study is to determine if there is a difference between glucose levels in the right arm and left arm in diabetic patients and to evaluate if cinnamon and aloe vera supplements impact glycemic control in diabetic patients.

The investigators seek to construct a novel, multimodal, distributed system that facilitates a new paradigm of home-based medical surveillance and treatment for frail older adults centered on timely diagnosis of movement system impairments and personalized intervention. Measurements from a heterogeneous set of complementary sensors will be combined with clinically-informed and data-learned dynamic models of human motion to enable real-time activity recognition (e.g., sitting, standing, walking) and movement assessments (e.g., speed, repetition, quality). As the study progresses, the system will be integrated with wearable assistive technology to provide "smart", activity-specific assistance of movement deficits or the activation of caregivers if a decline in function is detected. Finally, the investigators will test the combined assessment and intervention system in the clinic and the home, identifying challenges and solutions for the scaling up to unconstrained real-world settings.
