Crisis Response Planning is an efficacious, one-session intervention that increases positive affect, decreases negative affect and psychiatric hospitalizations, and reduces suicide attempts by 76% among Servicemembers. Crisis Response Planning is hypothesized to reduce suicidality by identifying a variety of personalized strategies that are designed to strengthen and/or promote emotion regulation processes.Research in nonmilitary samples suggests the effectiveness of emotion regulation strategies varies across situations. The applicability of these findings to suicidality among Servicemembers is unknown. Improved understanding of what strategies work under which circumstances and for whom will significantly advance our ability to prevent suicide among Servicemembers. Hypotheses include: 1. Use of self-management strategies, thinking about reasons for living, and seeking social support at time t will be associated with significant reductions in suicidal ideation at time t+1. 2. Use of distraction, reappraisal, and interpersonal emotion regulation strategies at time t will be associated with significant reductions in suicidal ideation at time t+1. 3. Affect intensity and social context will significantly moderate the time-lagged effects of Crisis Response Planning and emotion regulation strategy use on suicidal ideation. 4. Distinct profiles of demographic (e.g., gender, age), historical (e.g., prior suicide attempts), and psychological characteristics (e.g., emotion dysregulation, symptom severity) will predict who experiences a decrease in suicidal ideation following the use of Crisis Response Planning and emotion regulation strategies. 5. (Exploratory): Individuals who utilize their Crisis Response Planning more frequently and perceive Crisis Response Planning as more effective will be more likely to engage in mental health treatment at follow-up.

Several studies have reported that diabetic subjects have lower plasma vitamin C concentrations than non-diabetic subjects. Although urinary vitamin C loss in diabetic subjects was reported to be increased in two studies, these are difficult to interpret due to lack of controlled vitamin C intake, inadequate sampling, lack of control subjects, or methodology uncertainties in vitamin C assay and sample processing. Consequently, it is unclear whether diabetic subjects truly have both low plasma and high urine vitamin C concentrations. We propose that low plasma vitamin C concentrations in diabetic subjects are due in part to inappropriate renal loss of vitamin C in these subjects but not in healthy controls. We will study nondiabetic controls and cohorts with diabetes. Vitamin C concentrations in plasma, RBCs, and urine will be measured in outpatients. In those willing to be admitted to the Clinical Center, we will measure vitamin C pharmacokinetics to determine the relative bioavailability for vitamin C in individuals with and without abnormal urinary loss of vitamin C (or renal leak). Single nucleotide polymorphisms (SNPs) will be determined in genomic DNA responsible for the two proteins mediating sodium dependent vitamin C transport, SVCT1 and SVCT2. We will also explore mechanisms underlying abnormal urinary vitamin C loss.

Background: Negative emotional states can affect a person s behavior as they make decisions. For example, hunger may make people more impatient; they may then make riskier choices. Other negative emotional states that can change behavior include stress, pain, and sadness. By learning more about how emotions affect thinking and behavior in healthy people, researchers hope to better understand how to identify and treat people with mental disorders. Objective: To learn how negative emotions affect the brain and decision-making behavior. Eligibility: Healthy people aged 18 to 55 years. Design: Participants will have 3 clinic visits in 3 weeks. Participants will fill out questionnaires. They will be asked about their personal history, their personality, and state of mind. For 2 visits, participants will be assigned to different groups. Each group will experience 1 type of emotional stressor: Some participants will watch a video. Some will have to do arithmetic problems. Some will have heat applied to an arm or leg. Some will experience cold by immersing their hand in ice water. For a snack craving test, some will be tempted by food after a 4-hour fast. During these tests, participants will have sensors attached to their bodies. They will be videotaped. Saliva samples will be collected. After the stressors, participants will do tasks on a computer. They will need to make choices. Some participants will perform these decision-making tasks while lying in a brain scanner for functional magnetic resonance imaging. The brain scan involves lying on a table that slides into a cylinder that takes images of the brain. ...

This project proposes to use telemedicine-delivered cognitive-behavioral therapy (CBT) enhanced with continuous glucose monitor (CGM) review to target diabetes distress in adults with type 1 diabetes. The efficacy of CBT for diabetes distress (CBT-DD) will be tested in comparison to commercial FDA-approved CGM only in a randomized controlled clinical trial. The investigators' central hypothesis is that the addition of a CBT intervention that targets diabetes distress and self-management directly will yield clinically significant improvements in both diabetes distress and glycemic control relative to CGM alone. The investigators propose to recruit 93 adults (age 18-64) with type 1 diabetes from a national population for an entirely virtual 6-month study over four years, with targeted recruitment of racial/ethnic minorities. In addition to standard measurement of HbA1c for glycemic control and validated patient-reported outcome (PRO) surveys, the investigators plan to innovatively integrate momentary psychological and behavioral data via smartphone-based ecological momentary assessment with CGM data to assess day-to-day changes in diabetes distress, affect, self-management, and glycemia over the course of the trial.

The purpose of this study is to develop and evaluate the usefulness of MRI using 129Xe gas for regional assessment of pulmonary function. Specifically, three forms of 129Xe MRI contrast will be the investigators focus - 1) imaging of the 129Xe ventilation distribution, 2) imaging the alveolar microstructure via the 129Xe apparent diffusion coefficient (ADC), and 3) imaging 129Xe that dissolves in the pulmonary blood and tissues upon inhalation. Such imaging of 129Xe gas transfer is expected to be uniquely sensitive to pathologies affecting gas exchange (fibrosis, emphysema, pulmonary hypertension) and provide new insights regarding the normal resting heterogeneity of pulmonary gas exchange.

This study will examine the safety of giving the experimental drug, resiniferatoxin (RTX), to treat severe pain in patients with advanced cancer. RTX is a chemical extracted from a cactus-like plant. It is similar to capsaicin, the active ingredient in hot pepper. RTX has relieved pain and reduced the need for pain medication in several animal experiments. It works by destroying nerves that transmit pain information. People at least 18 years of age with severe pain from advanced cancer at or below the level of the chest that cannot be controlled with standard treatments may be eligible for this study. Participants undergo the following procedures: Pretreatment Visit Before beginning treatment with RTX, patients give a medical history and undergo a physical examination that includes: - Electrocardiogram (EKG) - Blood draw - Urinalysis - Neurological examinations - Peak expiratory flow rate (PEFR) - Eye examination - MRI - Urology assessment - Pregnancy test, when appropriate - Questionnaires to collect information on health, personality, mood, pain levels and symptoms. 2-Day Hospitalization Patients are hospitalized for 2 days for RTX injection and monitoring, as follows: - RTX injection: RTX is injected in the operating room under general anesthesia. It is given through a catheter placed in the patient s spine. The catheter is also used to obtain samples of cerebrospinal fluid (CSF) the clear fluid that bathes the spinal cord. The fluid is examined to assess drug effects and side effects, chemical changes in the content of the CSF associated with RTX, and how RTX is handled by the body. - Post-injection monitoring, including: - Surveys about symptoms such as pain or weakness - Neurological examinations - Blood and CSF sampling - EKG - AEs Outpatient followup - Vitals - Blood draw, Urinalysis, neurological and sensory testing, EKG on days 7, 14 and 30 after the injection - MRI scans of the head and back, Urology assessment and PEFR on day 15 after the injection - Eye examination - Follow-up phone calls monthly for 6 months
