Effectiveness of a Combined mHealth-CBT Psychological Intervention to Improve Psychological Well-Being in Young Patients With T1D

Type 1 diabetes (T1D) can lead to psychological adjustments that impact the acceptance and management of this health condition, as well as the overall quality of life of patients, especially among the young. Therefore, there is a need for psychological interventions aimed at enhancing the psychological well-being of children and adolescents with T1D. The goal of this non-randomized controlled trial is to evaluate whether a combined intervention comprising mHealth (using an app) and face-to-face psychological sessions based on Barlow's protocol and cognitive-behavioral therapy techniques (CBT) is effective in enhancing psychological well-being in children and adolescents with T1D. The main hypotheses are: * H1: The primary results expected to be obtained are a significant increase in psychological well-being, which means a decreased diabetes distress (DDS) (H1a) an increased subjective well-being (PANAS) (H1b) and a better self-efficacy for managing their emotions (RESE) (H1c). * H2: As secondary outcomes, it is also expected that the combined mHealth-CBT intervention would increase the level of positivity (P-Scale) (H2a), the self-esteem (RSES) (H2b) and the satisfaction with life (SWLS) (H2c).

Starting Technology in At Risk Type 1 Diabetes Study

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.

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 are expected 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.

Testing an Integrated Care Model Trial

This study aims to test the use of an adapted collaborative care model for improving the health outcomes of adults diagnosed with type 1 diabetes (T1D).

Effects of HBO on Glucose in Patients With DM

The purpose of this Research Study is: 1. To determine the reliability and performance of the Dexcom G6® continuous glucose monitoring (CGM) system in patients with diabetes undergoing hyperbaric oxygen (HBO2) exposure. The study-specific blood glucose meter and CGM system are approved by the FDA (U.S. Food and Drug Administration). 2. To determine whether HBO2 exposure causes blood glucose to drop as a result of the treatment. 3. To determine whether HBO2 causes a change in blood glucagon (a hormone that raises blood glucose). Investigators will be comparing changes in blood glucose and glucagon in volunteers with diabetes who will be exposed to a single hyperbaric oxygen treatment (pressurization to 2.4 atmospheres absolute for 90 minutes) to a control period of 2 hours where volunteers will simulate a hyperbaric treatment while sitting in an examination room breathing room air at sea level pressure. Investigators will be measuring blood glucose with a variety of devices including a continuous glucose monitor, two point-of-care glucometers, and the hospital inpatient laboratory measurement of venous blood.
