Diabetes Clinical Trials in Columbus, OH

This research study is called 'PRenatal and Obstetric Maternal Exposures and ISlet Autoantibodies in Early Life: The PROMISE Study'. The purpose of this study is to find out more about how exposures during pregnancy, such as having an infection, diet and growth may impact later risk of type 1 diabetes (TID) and islet autoimmunity in the child. We are also interested in finding out more about why having a father or sibling with T1D increases risk of autoimmunity in the child more than having a mother with T1D. We are enrolling women who are pregnant and either have T1D or another first degree relative (father or full sibling) of the baby has T1D. The biological father is also invited to enroll in study, as it is important to understand how the father's health and genetics may contribute to the child's risk of developing T1D. The study procedures for the mother, father and baby are explained below. Mother: Pregnant women will be asked to complete a visit once per trimester (3 visits) during pregnancy and one visit up to 12 weeks after delivery. At each visit, mothers will consent to a blood draw, collection of biological samples and the completion of questionnaires. . Mothers who have T1D will also be asked to download any diabetes device data they have, such as continuous glucose monitor or insulin pump data. Father: The (biological) father will be invited to enroll in a single visit. He will consent to a blood draw and completion of questionnaires. Fathers with T1D will also be asked to download any diabetes device data they have, such as continuous glucose monitor or insulin pump data. Baby: The baby will have blood collected at birth to determine the genetic risk for T1D. Families will consent to the completion of questionnaires about growth, health and diet at 6, 12, 18 and 24 months of age and between 5-7 years of age, and to complete blood testing for islet autoantibodies at 24 months and between 5-7 years of age. For those children with a high genetic risk score, we will also collect blood for autoantibody testing at 6, 12, and 18 months of age. Read Less

We propose a pragmatic, unblinded, randomized controlled, single center trial of 56 pregnant individuals with Gestational diabetes mellitus (GDM). Our study proposes a pragmatic randomized control trial of patient led rapid titration of basal insulin compared to standard therapy. There is a planned subgroup analysis of patients with and without concomitant metformin usage. Patients will continue routine clinic visits. Patients who are initiated on basal insulin or started on night-time basal insulin within 7 days will be approached about the study. Patients who agree to be enrolled will sign informed consent.

This study is being done to evaluate how a ketone ester (KE) beverage affects heart function and health in people with heart failure compared to a placebo beverage (a beverage made with standard food ingredients that do not contain ketone esters). Read Less

Lower attainment of cardiovascular health (CVH), indicated by the American Heart Association's Life's Simple 7 (LS7; physical activity, diet, cholesterol, blood pressure, body mass index, smoking, glycemia) and Life's Essential 8 (LE8; LS7+sleep) metrics, is a major contributor to Black men having the shortest life-expectancy of any non-indigenous race/sex group. Unfortunately, a paucity of literature exists on interventions aimed at improving CVH among Black men. The team of clinician scientists and community partners co-developed a community-based lifestyle intervention titled Black Impact: a 24-week intervention for Black men with less-than-ideal CVH (<4 LS7 metrics in the ideal range) with 45 minutes of weekly physical activity, 45 minutes of weekly health education, and engagement with a health coach, group fitness trainer, and community health worker. Single-arm pilot testing of the intervention (n=74) revealed high feasibility, acceptability, and retention and a 0.93 (95% confidence interval: 0.40, 1.46, p<0.001) point increase in LS7 score at 24 weeks. Secondary outcomes included improvements in psychosocial stress (i.e., perceived stress, depressive symptoms), patient activation, and social needs. Thus, robustly powered clinical trials are needed to determine the efficacy of Black Impact and to evaluate the underlying interpersonal and molecular pathways by which Black Impact improves psychosocial stress and CVH. Thus, the investigators propose a randomized, wait-list controlled trial of Black Impact. This novel, community-based intervention to provide a scalable model to improve CVH and psychosocial stress at the population level and evaluate the biological underpinnings by which the intervention mitigates cardiovascular disease risk. The proposed study aligns with American Heart Association's commitment to addressing CVH equity through innovative, multi-modal solutions. Read Less

Gestational Diabetes Mellitus (GDM) is a common metabolic complication of pregnancy defined as new onset hyperglycemia during gestation. GDM conveys significant risk of morbidity and mortality for both mother and infant. An estimated 268,900 infants were born to mothers with GDM in the USA, accounting for approximately 6.9% of births. Although individual correlations have been found between elevated GGT and uric acid levels and later development of GDM, no research has established and validated combined criteria for GGT and uric acid levels that would lead to their use in identifying women at high risk of GDM in the first trimester. Central Hypothesis: Serum GGT and serum uric acid collected between >9-14.0 weeks gestation will be significantly elevated in women who later develop GDM compared to those who do not. Combined analysis of serum uric acid and GGT levels within the first trimester allows for accurate prediction of the development of GDM. Study population includes women between 9-14 weeks gestation undergoing a standard first trimester blood draw. Additional blood will be drawn during the standard blood draw to assess GGT and uric acid levels. Research participants will be tracked afterwards to determine whether they tested positive for gestational diabetes during the standard testing process which typically occurs at 24-28 weeks gestation. The data will then be analyzed to estimate the sensitivity, specificity, positive and negative predictive values of the first trimester GGT and uric acid tests. The GGT and uric acid levels which maximize the area under the receiver-operator characteristic curve will be identified. Read Less

Diabetes mellitus affects roughly 8% of pregnancies but is associated with significant perinatal and maternal morbidity, with 6% of pregnancies affected by gestational diabetes mellitus (GDM). Best practice guidelines recommend universal screening for gestational diabetes mellitus between 24-28 weeks of pregnancy in all women who do not have a diagnosis of pre-gestational diabetes mellitus. Among high-risk populations, performing an early diabetes screen is suggested at the initiation of prenatal care to evaluate for pre-gestational diabetes mellitus. Prior studies have demonstrated a difference in perinatal outcomes by comparing women with negative screening tests to those who fail a screen but pass a diagnostic test and those who are ultimately diagnosed with GDM. The investigators aim to use continuous glucose monitoring systems to study glycemic control in the early third trimester to further elucidate the differences between pregnant women with euglycemia, glucose intolerance, and GDM.

Diabetes mellitus (DM) affects roughly 8% of pregnancies and is associated with significant perinatal and maternal morbidity. Current obstetric practice is complicated by the emergence of the SARS-COV-2 pandemic, resulting in morbidity and mortality secondary to complications of COVID-19. Care coordination among the teams caring for women admitted for antepartum, intrapartum, and postpartum care with suspected or confirmed COVID-19 is required to conserve PPE and minimize staff exposure. The investigators propose a pilot proof of concept randomized study to evaluate the utility of Dexcom-G6 continuous glucose monitors for assessment of glycemic control in pregnant and postpartum women with insulin-requiring diabetes mellitus during hospitalizations, as a proof of concept in the efforts to reduce the number of point of care glucose tests needed, reduce staff exposure, and conserve PPE use.
