Every unit in the Connecticut Army National Guard has a Suicide Intervention Officer to provide suicide intervention education awareness for their unit, monitor for soldiers in crisis and connect soldiers with helping resources and agencies. Suicide Intervention Officers need support in this difficult role, yet there is limited guidance on how to help them. This study will shed light on how to support Suicide Intervention Officers and whether this support results in reduced suicide risk in their units. Read Less

Older people with HIV (OPH) often live with significant mental health challenges such as social isolation, loneliness, and depression. The objectives of this study are to develop and test the usability and feasibility of a technology-based psychosocial intervention program designed to: enhance social engagement and support; facilitate resource access and education; reduce loneliness; and improve well-being among older adults with HIV who are long-term survivors (diagnosed with HIV ≥ 20 years). The program, Connecting Older Positive People to Enhance Health and Resilience (COPPEhR), will build on Dr. Sara Czaja's PRISM (A Personal Reminder and Information Management System for Seniors) platform, and will be an easy-to-use software application (app), preloaded onto a standard device, designed to support social connectivity, memory, and access to resources for older adults at risk for isolation and the programs and services available at the Center for Special Studies (CSS) at Weill Cornell Medicine (WCM). This protocol covers Phase 2 of the study, which will be a pilot randomized controlled efficacy trial will compare the COPPEhR intervention to a device-only control condition. Participants in the control condition will receive the same device as those in the COPPEhR condition without the COPPEhR application. The specific aims of this developmental project are to evaluate the feasibility, usefulness, and usability of a state-of-the art technology-based multicomponent COPPEhR intervention for aging adults with HIV. Our hypothesis is the COPPEhR intervention will be feasible, usable and useful. The hypothesis is that those that use the COPPEhR app will experience less loneliness, less depression, and less social isolation and more social support, more resilience, and more connectivity than those that do not use the COPPEhR app. Read Less

Investigators will assess the usefulness of using ultrasound in office procedures for laryngology interventions. Participants who qualify will be adults who are undergoing superior laryngeal nerve block, injection laryngoplasty, swallowing evaluation, voice evaluation and voice therapy. Read Less

This is a phase 2b open-label trial to characterize histopathological biomarkers of disease in immunoglobulin A nephropathy (IgAN) and demonstrate potential changes in response to sibeprenlimab. Read Less

This randomized clinical trial (RCT) evaluates whether metformin can reduce systemic inflammation and improve immune function in individuals with a history of injection drug use, with or without HIV. Participants will receive metformin or placebo and undergo immune system assessments, including vaccine response evaluations. Read Less

This study has been initiated to evaluate the question, "What is the best way to protect the palate after a gum graft is removed?" The overall objective is to determine if there is a difference in PROMs of donor site healing using different palatal post-operative protection techniques. Read Less

The primary goal of this research is to evaluate the effect of daily whole-cooked chickpea and lentil consumption for 8-weeks on gut health, including microbiome-metabolome arrays and gut epithelial/barrier function, in healthy young adults. Secondary Objectives include: * To examine the effect of daily whole-cooked chickpea and lentil consumption for 8-weeks on the measures of metabolic health and inflammation in healthy young adults. * To determine the feasibility of healthy young adults to successfully incorporate and sustain the recommended daily intake of pulses into their diets for eight consecutive weeks Research Interventions: Participants will be asked to consume a normal diet supplemented daily with either A) whole-cooked canned lentils, or B) whole-cooked canned chickpeas. The control condition will be instructed to consume a normal diet while restricting all pulse intake throughout the study. Read Less

Naturalistic developmental behavioral interventions (NDBIs) are a newer class of evidence-based interventions for young autistic children to promote their positive developmental or behavioral outcomes. These are often delivered by family members or other natural change agents given the emphasis on naturalistic transactions between an adult and a child. Despite the emerging evidence, there are practical difficulties that hinder wider dissemination and implementation of NDBIs, including low level of access to some of these branded, packaged NDBIs. To mitigate these difficulties related to access, we have created a series of video modules that demonstrate nine commonly used core components in NDBI strategies. In this study, caregivers will receive training and coaching using these modules and both synchronous and asynchronous coaching from a clinician. In this type 1 hybrid implementation trial, there are two groups of participants: (1) caregivers of young autistic children or children with other developmental disabilities/delays, (2) children, and (3) clinicians. Caregivers will meet with clinicians virtually weekly to (a) watch the newly developed NDBI videos that demonstrate the strategy use, (b) discuss how this might be applied to their own child, (c) receive individualized homework planning, (d) record and upload videos of their practice of strategy use with their own child, and (e) review the videos with clinicians to receive individualized feedback on their strategy use. This will occur for 10 weeks. Each session will be video recorded to assess the clinicians' intervention fidelity. After 10 weeks, pre-post tests will be conducted to assess parents' confidence on implementing these strategies, their child's social communication, and satisfaction of providers and caregivers. Qualitative data will also be collected via interviews with some selected participants to gain a deeper understanding of their perceptions. Read Less

This study will use a randomized placebo-controlled trial to examine smaller doses of choline and whether a signal in the brain is detectable using fMRI. This study will examine if an even smaller doses of choline can show these similar brain activation and connectivity patterns to the 1650 mg dose. This will be a dose ranging study of 550 mg and 1100 mg oral choline compared to placebo. Read Less

The study will explore the effects of early intensive antiretroviral therapy (ART) with or without a broadly neutralizing antibody (bNAb) on achieving HIV remission (HIV RNA below the limit of detection of the assay) among infants living with HIV. Read Less

Traumatic injury is a leading cause of morbidity and mortality in young adults, and remains a substantial economic and health care burden. Despite decades of promising preclinical and clinical investigations in trauma, investigators understanding of these entities is still incomplete, and few therapies have shown success. During severe trauma, bone marrow granulocyte stores are rapidly released into the peripheral circulation. This release subsequently induces the expansion and repopulation of empty or evacuated space by hematopoietic stem cells (HSCs). Although the patient experiences an early loss of bone marrow myeloid-derived cells, stem cell expansion is largely skewed towards the repopulation of the myeloid lineage/compartment. The hypothesis is that this 'emergency myelopoiesis' is critical for the survival of the severely traumatized and further, failure of the emergency myelopoietic response is associated with global immunosuppression and susceptibility to secondary infection. Also, identifying the release of myeloid derived suppressor cells (MDSCs) in the circulation of human severe trauma subjects. This process is driven by HSCs in the bone marrow of trauma subjects. Additionally, MDSCs may have a profound effect on the nutritional status of the host. The appearance of these MDSCs after trauma is associated with a loss of muscle tissue in these subjects. This muscle loss and possible increased catabolism have huge effects on long term outcomes for these subjects. It is the investigator's goal to understand the differences that occur in these in HSCs and muscle cells as opposed to non-injured and non-infected controls. This work will lead to a better understanding of the myelopoietic and catabolic response following trauma. Read Less
