Many youth and young adults (YYAs) with type 1 diabetes (T1D) and type 2 diabetes (T2D), particularly those of minority race/ethnicity, do not achieve optimal glycemic control and household food insecurity (HFI) may be a key barrier. HFI is the limited or uncertain availability of nutritionally adequate and safe foods. The SEARCH Food Security (SFS) cohort study is designed as an ancillary study to the ongoing NIH/NIDDK-funded SEARCH for Diabetes in Youth 4 Cohort study. The aims of the SFS study are to (1) Initiate a food insecurity cohort study of 1,187 YYAs aged 15-35 years (53% minority) with T1D and T2D by adding two data collection time points to the ongoing SEARCH 4 study in three of the five SEARCH sites, including South Carolina, Colorado and Washington; (2) Evaluate how HFI influences changes in glycemic control in YYAs with T1D and T2D; (3) Identify the pathways through which food insecurity may act; and (4) Evaluate the influence of HFI on changes in health care utilization and medical and non-medical health care costs in YYAs with T1D and T2D.
This research will develop and test a nutrition-focused mobile-support program for head and neck cancer patients and their caregivers at the end of treatment.
Phase I: To guide system development, we will conduct interviews with 15 individuals with head and neck cancer and their caregivers to understand the nutritional challenges faced at the end of treatment. We will also recruit 35 oncology dietitians to complete online surveys to identify key caregiver nutritional support tasks and caregiver demands.
Phase II: After system development, we will recruit 33 head and neck cancer patients and their main supporters to pretest our nutrition support system. Participants will be asked to complete two surveys and a one-time clinic session. The clinic session will include information and resources about symptoms and concerns and after the visit, the program will provide follow-up resources and support online for one month. Lastly, we we will conduct individual/small group interviews with 10 head and neck health care providers to evaluate feasibility and recommendations for future system development.
The information from this study may help us to improve supportive care programs in the future to help others as they complete head and neck cancer treatment.
This study will recruit adolescents who are enrolled in a Teen Health Careers Program to participate in a community-engaged study. This study will seek to understand the barriers and facilitators to physical activity and nutritious foods throughout their daily lives. Adolescents will use take digital images to capture aspects of their daily lives using photography.
We are conducting the INSIGHT COPD study because symptoms of chronic obstructive pulmonary disease (COPD) and high body mass index (BMI) overlap. There are many medications for patients with COPD, but there is little mention of weight loss as a possible treatment in current research. We are trying to find out if a lifestyle program that promotes modest weight loss and increased physical activity will improve COPD symptoms and lead to better exercise tolerance for those with a high BMI. We are also looking at the effects on shortness of breath, quality-of-life, and cardiovascular disease risk factors. The INSIGHT COPD trial is taking place at many sites across the United States including MUSC, and is planning to enroll approximately 1000 people.
Low vitamin d levels are common among patients undergoing orthopedic surgery. However, very little is known about how vitamin d affects outcomes in patients undergoing total joint replacement surgery. Our study will look at how common low vitamin d status is among patients undergoing total hip and total knee replacement surgery. We will also look at how vitamin d levels affect complication rates and hospital readmission rates.
The Sponsor is conducting a clinical study with STP206 for the prevention of Necrotizing Enterocolitis (NEC) in preterm infants weighing less than 4.4 lbs. (2000g). NEC is the most common serious disease of the gut in preterm infants. The purpose of this study is to look at the safety of STP206 in babies born early, and to get early information on whether STP206 may prevent NEC.
STP206 is an investigational product, meaning it is not yet approved by the US Food and Drug Administration for use in the United States. STP206 contains live bacteria and is considered a Live Biotherapeutic. The two types of bacteria are Lactobacillus and Bifidobacteria. These bacteria are used in foods such as cheese, yogurt, sauerkraut, and pickles, and have been consumed safely for years and are commonly contained in probiotic products that are currently sold throughout the world. These bacteria also are normally present in parts of the body such as bowel, mouth, skin, and the vagina. These bacteria generally do not cause disease. There have been studies of probiotic bacteria in premature babies that suggest these types of bacteria are effective in preventing NEC. The purpose of this study is to determine the safety of STP206 and if it is effective in preventing NEC.
In this study, we will evaluate the impact of the dietary supplement of krill oil concentrate, which contains the omega-3 HUFAs, on the success of U.S. Army officers training outcomes in Infantry Basic Officer Leadership Course (IBOLC) training Part I) and Ranger training (Part II). We are researching the effects on key performance measures from the two parts of their training, as well as underlying psychological and cognitive functioning that are components of success. The questions addressed by this study are:
1. Will treatment with krill oil concentrate containing the omega-3 HUFAs improve cognitive and psychiatric functioning during U.S. Army Infantry Basic Officer Leadership Course (Part I)?
2. Will treatment with krill oil concentrate containing the omega-3 HUFAs improve the performance of officers during portions of the U.S. Army Infantry Basic Officer Leadership Course (Part I) and Ranger training (Part II)? This phase will combine the cognitive and physiological challenges from which we measure performance outcomes.
3. Do effects of the supplements continue once a person stops taking them? Are there any group differences in functioning observed 2 months after treatment is discontinued (i.e., after Ranger training)?
A small sub-study will address the same questions among older, more experienced Army personnel in Part I only.
