This post-market surveillance study is primarily designed to demonstrate the ongoing safety of the Control-IQ system, the ongoing performance of glycemic control and quality of life with Control-IQ system use, and the rate of use of the Control-IQ system. The system will be assessed in all approved populations during the first 12 months of use.

The goal of this study is to learn if treating insomnia with a therapy intervention in people with type 1 diabetes will help to better control sugar levels, sleep, and quality of life. The questions this study aims to answer include: Will this intervention help the insomnia symptoms? Will obtaining better sleep aid in the control of diabetes through measures like sugar levels? Will the intervention help with quality of life factors like mood and fatigue? Researchers will compare participants receiving the therapy intervention for sleep with those in the "healthy living" intervention to see if the outcomes are different based on the treatment. Participants in the therapy intervention group will: * meet virtually with a therapist for 8 sessions via Zoom. Once a week for the first 4 weeks and then every other week for the last 4 sessions. Participants in the healthy living group will: * receive weekly health education emails * receive brief weekly calls from a coach to answer any questions Participants, regardless of intervention, over the 12 week study period will: * monitor their sleep for 2 weeks through a sleep-monitoring watch * share their continuous glucose monitoring data throughout the study * answer questionnaires prior to the intervention, halfway through the intervention and then after the intervention * attend 3 in person office visits

The purpose of this study is to evaluate how well LY4057996 is tolerated and what side effects may occur in healthy participants and participants with Type 1 and Type 2 Diabetes. The study drug will be administered either subcutaneously (SC) (under the skin) or intravenously (IV) (into a vein in the arm). Blood tests will be performed to check how much LY4057996 gets into the bloodstream and how long it takes the body to eliminate it. The study will last 11 weeks for Part A1-A2, 4 weeks for A3-A5, 6 weeks for Part B and 7 weeks for Part C, all approximations, excluding a screening period.

The goal of this prospective, single-arm observational study is to characterise a home-based setup and telemonitoring care model for an advanced hybrid closed-loop insulin pump system (Tandem Control-IQ) in adults with type 1 diabetes. The study characterises safety, glycaemic outcomes, direct healthcare costs, and impact on quality of life and user experience over 12 months. The main research questions are: * What is the safety profile of initiating the insulin pump system at home, measured by the percentage of sensor time spent below 54 mg/dL at 12 months? * What longitudinal changes in glycaemic metrics (such as Time in Range) are observed within the cohort following home-based initiation? * What changes in quality of life, technology satisfaction and healthcare experience are observed during follow-up? * What are the direct healthcare costs and resource utilization patterns associated with this care pathway from a public healthcare system perspective? Participants will: * Complete an online technical training course prior to system activation. * Receive a home visit from a specialised nurse to configure and start the insulin pump system. * Have their continuous glucose monitoring data reviewed remotely every 14 days by the nursing team to manage automated clinical alerts. * Attend scheduled clinical follow-up assessments at 1, 3, 6, and 12 months. * Complete questionnaires assessing quality of life, patient experience, and device satisfaction.

This retrospective multicenter cohort study aims to evaluate the effectiveness of an interprofessional cooperative protocol allowing dietitians to adjust prandial insulin-to-carbohydrate ratios in adults living with type 1 diabetes receiving functional insulin therapy. Glycemic outcomes will be assessed using continuous glucose monitoring data collected during routine clinical care. The primary endpoint is the change in Time in Range (TIR) between baseline and 6 months.

The goal of this clinical trial is to evaluate the effects of low-level light therapy on cellular energy and oxidative stress in healthy adults and patients with Type 1 diabetes. The main questions it aims to answer are: Does light therapy change adenosine triphosphate (ATP) levels and cytochrome c oxidase activity in blood cells? How does the intervention affect oxidative stress markers, specifically glutathione and malondialdehyde concentrations? Researchers will compare blood samples collected before the light therapy to those collected afterward to see if the intervention alters mitochondrial function. Researchers will also compare the responses of healthy volunteers to those of diabetic patients. Participants will: Provide a baseline blood sample. Receive red and near-infrared light exposure (660 nm and 850 nm) on their arms for 10 to 20 minutes using a therapy pad. Provide a final blood sample immediately after the light exposure.

Diabetes technology has revolutionized T1D management, disparities in technology access are evident among racial-ethnic minorities, patients with lower socioeconomic status and those with poorly controlled T1D (A1c\>8.5%). In order to examine whether diabetes technology can reduce diabetes care burdens and enhance outcomes among some of highest need patients, diabetes technology clinical trials must be expanded beyond the very select populations included in studies thus far (ie., mostly White, higher SES). Therefore, the investigators propose to perform a pilot RCT of hybrid closed-loop insulin pump therapy (HCL) in 40 diverse adult patients with poorly controlled T1D (HbA1c \>8.5%) from the largest academic and safety net health systems in the Los Angeles region to determine the feasibility of a RCT in this population and identify facilitators and barriers of effective use of closed loop insulin pump therapy in patients with poorly controlled T1D.

The main purpose of this study is to learn more how tirzepatide affects stomach emptying in participants with Type 1 Diabetes Mellitus (T1DM) and overweight or obesity. Participation in this study will last about 8 weeks, including screening and follow-up.

The goal of this controlled pre-post-trial is to test the Accu-Chek SmartGuide continuous glucose monitoring (CGM) system and whether its predictive features provide additional benefits for adults with type 1 diabetes or insulin- treated type 2 diabetes. The main questions this study aims to answer are: * Does using the Accu-Chek SmartGuide together with the Predict App change participants' fear of hypoglycemia? * Does the Predict App affect other psychological and behavioral outcomes, such as sleep quality, confidence in preventing hypoglycemia, diabetes- related distress, and diabetes empowerment? * Does the use of the predictive features affect glucose levels and the way participants use and respond to CGM alarms and trend information? Participants will use the Accu-Chek SmartGuide for 6 weeks. During the first 2 weeks, participants will use the CGM system without the predictive features. During the following 4 weeks, participants will use the system together with the Accu-Chek SmartGuide Predict App. Participants will complete online questionnaires at two time points (after 2 and after 6 weeks) and answer short questions twice a day through a smartphone app during the first 2 weeks and the last 2 weeks of the study. CGM data will be collected throughout the study. A subgroup of 10 participants will also be invited to take part in an online interview about their experiences with the predictive features.

The investigators will test the hypothesis that, in adults with type 1 diabetes (T1D), glucagon-like peptide-1 receptor agonism (GLP-1RA, i.e. dulaglutide) enhances insulin-mediated skeletal muscle microvascular perfusion via attenuating endothelial oxidative stress and thereby improving endothelial function.

This study seeks to address the multifaceted challenges posed by food disparities and their negative consequences on health outcomes, via a comprehensive community health intervention program. Study objectives include: 1. To describe the social-demographic and clinical factors associated with food insecurity in the hospitalized diabetic population. 2. To design, implement and evaluate a nutrition program targeting the hospitalized diabetic population. The investigators will prospectively randomize the target population into either a nutrition program (Intervention), or state-of-art standard of care (SOC) in a 4:1 ratio. Participants in the intervention group will be provided the following two resources in addition to SOC: 1) Enhanced access to nutritious food (twice daily meal delivery up to 90 days post-discharge) 2) Education at discharge and continuing outreach to enhance knowledge for better diet and food options. 3. To enhance community engagement and develop a systematic implementation plan for long-term roll-out of the nutrition program.

A pilot study to evaluate and compare glucose metrics using a real-time continuous glucose monitor (FreeStyle Libre 3 sensor) between patients with diabetes and gastroparesis and those with diabetes without gastroparesis.

50 children/adolescents (ages 6 to \<18yrs) with T1D in suboptimal control (HbA1c≥8.0%) and lower SES (below 200% poverty line) on insulin therapy (either injections or open-loop pumps) will be recruited at Nemours \~ 1/3 each AA, Hispanic/Latino, non-Hispanic whites. All families that qualify and agree to transition to closed-loop technologies will be recruited to allow data to be gathered before and after use of devices. They will go through the process of approval with the assistance of an insurance navigator in clinic. Those not a CGM will be prescribed one as well. Diabetes care will be 'real life', devices will be prescribed, and care per clinic routine with periodic device downloads. Principal outcome, time-in-range, will be analyzed at 3-months compared to baseline, each participant their own control. Secondary outcomes including HbA1c, other glucose metrics and questionnaires related to use of technology and diabetes distress will be also analyzed. All outcomes will also be collected at 6-months. Results could have important and fast applicability to the field and help better inform decision makers, including payers, clinicians, and patients and families and could serve to decrease health care disparities in this needy population.

The main purpose of the study is to check: * Can therapy with a preparation of regulatory cells (Tregs lymphocytes) and/or an anti-CD20 antibody preparation (rituximab) be successfully used in children with pre-diabetes to treat or delay type 1 diabetes? * Is therapy with a preparation of regulatory cells (Tregs lymphocytes) and/or a preparation of antiCD20 antibodies (rituximab) safe for children with pre-diabetes, and what side effects may be associated with it? The study will include patients at high risk for type 1 diabetes whose laboratory tests have confirmed preserved normal/high insulin production. First (part 1 of the study), tests will be performed to determine the risk of the disease (determination of autoantibodies that characterize the autoimmune background). In order to confirm the effectiveness of the therapy, not all patients will receive the study treatment. The study will be a so-called blinded randomized trial. This means that in this trial, all participants will undergo the same study procedures, but the participant will be randomly assigned to one of four (4) groups that will receive different treatment regimens before entering the study. The participant will be randomly assigned to one of four groups: * Group I will receive a preparation of regulatory cells (Tregs lymphocytes) along with a preparation of antiCD20 antibodies, * Group II will receive a preparation of regulatory cells (Tregs lymphocytes) together with an inert substance (placebo) * Group III will receive a preparation of antiCD20 antibodies along with a sham treatment (inert substance) * Group IV will receive an agent containing an inert substance and sham treatment. Approximately 150 patients aged 3-18 who are at risk of developing type 1 diabetes will be enrolled in the study, which will last up to 96 months. Each enrolled participant will remain in the study for up to five years.

This investigator-initiated study will enroll about 30 adults 18 to 65 years of age with type 1 diabetes (T1D) who are using the Tandem t:slim X2 insulin pump or Tandem Mobi insulin pump with Control-IQ or Control-IQ+ technology ("Control-IQ" which will refer to either Control-IQ or Control-IQ+). The study is being done to find out if inhaled insulin given for a meal is safer and better to use than a bolus of insulin through your pump when you exercise following a meal. Participants are asked to complete three study exercise visits in the clinic.

This is a prospective randomized placebo-controlled double-blind crossover pilot study determining the effect of dichloroacetate on brain function under clamped hypoglycemia in T1DM.

Reason for the study The participants have been diagnosed with type 1 diabetes and are being treated with standard insulin therapy. The sponsor of the study is developing a new insulin-based medicine that can be taken by mouth (orally). For this reason, the investigational product named SCD0503 is to be tested in the study. The sponsor wants to investigate the course of blood concentrations and the blood sugar-lowering effect of the investigational product and to find out whether SCD0503 is safe. Investigational product tested in this study The investigational product tested, SCD0503, is still under clinical evaluation and has not yet been approved for your treatment. The active ingredient is regular human insulin, which has been used for many years in approved medicines for the treatment of diabetes. SCD0503 is being used in humans for the first time in this study. Study procedures The study will last for approximately 1 to 4 months. During this time, the participant will come to the investigational site 8 times for visits. During 4 visits the participant will undergo a clamp examination. The blood sugar-lowering effect of the investigational product is determined using a clamp device, a computer-controlled device that maintains blood sugar at a constant level within the normal range. This is achieved by infusing a sugar solution. During 2 further visits the participant will have a meal test. During the meal test, the blood sugar-lowering effect of the investigational product is determined after intake of a standardized meal as breakfast. You will have catheters in your arms to take blood, measure your blood sugar level and to infuse glucose (sugar) or insulin, if needed. SCD0503 is compared with a regular human insulin already approved for the treatment of diabetes. The participant will receive SCD0503 and the comparator product during different visits to the investigational site. The participant will also receive a placebo together with the investigational or the comparator product. The placebo looks identical but contains no active ingredient. As the investigational product is administered orally and the comparator product is injected under the skin, two placebos are used in this study. The order of medications given will be decided by chance, using a pre-defined method called randomization (a procedure similar to flipping a coin). Neither the participant nor the study physician will know which of the 2 medicines is administered at the respective dosing occasion. However, in case of emergency, this information will be quickly available.

The goal of this observational study is to evaluate the predictive value of the genetic risk score for type 1 diabetes in the progression to insulin deficiency in diabetic patients. The main question it aims to answer is: 1. To investigate the predictive efficacy of the genetic risk score for T1DM in determining whether diabetic patients will progress to insulin deficiency; 2. To compare the differences in genetic characteristics between the insulin-deficient cohort and the non-insulin-deficient cohort. This study is a nested case-control study, in which a case group and a control group are set up for the collection of observational indicators. Case group: Diabetic patients who "progressed to insulin deficiency" and those who "progressed to severe insulin deficiency". Control group: Patients who did not progress to insulin deficiency. The study period is 3 years.
