Recurrent Hypoglycemia in Type 1 Diabetes (Aim 2)
This study will explore the cerebral mechanisms of impaired awareness of hypoglycemia (IAH) in type 1 diabetics following exposure to experimental recurrent hypoglycemia (HG). To induce IAH, patients with T1D identified to have normal awareness of hypoglycemia (NAH) will undergo three 2-hour long hypoglycemic clamps. Neurochemical profiles will be measured by high field MRS before and after induction of IAH. Subject glycemic variability and activity/sleep for 1 week before each study will be monitored as all factors have been shown to alter responses to HG.

Cellular Therapy for Type 1 Diabetes Using Mesenchymal Stem Cells
The goal of this study is to determine the safety and efficacy of fresh metabolically active allogeneic umbilical cord-derived mesenchymal stromal cells (UC-MSCs) for the treatment of new-onset type 1 diabetes (T1D) and to understand the mechanisms of protection. If proven effective, such a strategy can be used as a therapeutic option for T1D patients and potentially other autoimmune disorders.

Hybrid Closed Loop Effectiveness Trial in Adults With Type 1 Diabetes
Minoritized individuals with type 1 diabetes (T1D) have approximately 2% higher average A1c levels and twice the rate of hospitalizations, complications, and mortality as their white counterparts. However, the efficacy trials establishing the benefits of hybrid closed loop (HCL) pump therapy in T1D have been in more socially advantaged and predominantly non-Hispanic white patients. Use of this technology by individuals with T1D from underserved communities remains very low. The investigators plan to conduct a randomized effectiveness trial - with broader eligibility criteria (including markedly elevated A1c) and longer follow up than the previous HCL efficacy trials - to evaluate the benefits, safety risks and treatment complications of HCL use in underserved adults with T1D. A comprehensive mixed-methods approach will be implemented to capture information about the user experience. Participants will be randomized (3:1 ratio) to one of three FDA-approved HCL systems or continuous glucose monitoring and multiple daily injection therapy. Subjects will be followed for 9 months to collect data on effectiveness (glucose % time-in-range 70-180 mg/dL and % time \< 70 mg/dL), safety (diabetic ketoacidosis and severe hypoglycemia events) and patient experience using the systems (including benefits and burdens, the impact of life stressors on HCL use, and how the match between HCL system functionality and the individual's needs and expectations impacts on user experience).

Diabetes Multimorbidity Typology, Trajectory, and Feasibility of an Audio Diary Mobile Application to Support Self-management
The goal of this clinical trial is to evaluate whether an audio diary mobile application (Fabla-diabetesMM) is feasible to use and may support self-management in older adults with type 1 or 2 diabetes and multimorbidity. The main questions it aims to answer are: * Is it feasible to adapt and implement the Fabla-diabetesMM audio diary mobile app among 30 older adults with diabetes and multimorbidity * Does the use of the audio diary mobile app affect self-management outcomes

Efficacy and Safety of a Ketogenic Diet in Type 1 Diabetes
Despite strong evidence that tight control of blood sugar reduces the risk of diabetes complications, most people with type 1 diabetes do not achieve recommended blood sugar targets. This randomized controlled trial will test whether a very-low- carbohydrate ketogenic diet can effectively and safely improve blood sugar control in adults with type 1 diabetes.

Menstrual Cycle Mapping While Using Closed-Loop Insulin Delivery
The hypothesis is that menstrual cyclicity affects glucose and energy metabolism in women with type 1 diabetes. The rationale of the hypothesis on cycle effects builds on the assumption that fluctuations of female sex hormones across the menstrual cycle cause changes in physiological parameters of glucose metabolism and energy homeostasis and/or lifestyle aspects involved in the regulation of blood glucose and body weight. It is expected that hormone fluctuations affect insulin sensitivity, gastric emptying, eating behaviour and energy expenditure. It is anticipated that insulin sensitivity is highest in the pre-ovulatory phase and lowest in the mid-luteal phase. It is further expected that gastric emptying peaks in the follicular phase, and highest energy expenditure and dietary intake during the mid-luteal phase. The primary objective of this study is to characterize glucose and energy metabolism throughout the menstrual cycle in natural cycling women with type 1 diabetes. Further objectives are to assess the impact of the menstrual cycle on glucose control and insulin requirements, investigate how fluctuations in sex hormone levels influence glucose and energy metabolism, and quantify both inter- and intra-individual variability in metabolic changes related to the menstrual cycle. Additionally, the study will evaluate whether changes in key physiological components of glucose metabolism and behavioural factors mediate menstrual cycle-related variations in glucose control and insulin requirements.

Genetics Of Autoimmunity In Type I Diabetes
The purpose of this study is to gain more information about the step-by-step process that causes someone to develop type 1 diabetes. Scientists think that a person's own immune system, directed by genetic and environmental factors play a major role in its development. Participation involves a blood draw, a brief medical history questionnaire and measurements of height and weight. Some participants will be asked to return for annual follow-up visits for 10 years.

Food Insecurity Reduction & Strategy Team
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.
