This phase III trial compares the effect of selumetinib versus the standard of care treatment with carboplatin and vincristine (CV) in treating patients with newly diagnosed or previously untreated low-grade glioma (LGG) that does not have a genetic abnormality called BRAFV600E mutation and is not associated with systemic neurofibromatosis type 1. Selumetinib works by blocking some of the enzymes needed for cell growth and may kill tumor cells. Carboplatin and vincristine are chemotherapy drugs that work in different ways to stop the growth of tumor cells, either by killing the cells or by stopping them from dividing. The overall goal of this study is to see if selumetinib works just as well as the standard treatment of CV for patients with LGG. Another goal of this study is to compare the effects of selumetinib versus CV in subjects with LGG to find out which is better. Additionally, this trial will also examine if treatment with selumetinib improves the quality of life for subjects who take it.

This phase III trial studies if selumetinib works just as well as the standard treatment with carboplatin/vincristine (CV) for subjects with NF1-associated low grade glioma (LGG), and to see if selumetinib is better than CV in improving vision in subjects with LGG of the optic pathway (vision nerves). Selumetinib is a drug that works by blocking some enzymes that low-grade glioma tumor cells need for their growth. This results in killing tumor cells. Drugs used as chemotherapy, such as carboplatin and vincristine, work in different ways to stop the growth of tumor cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. It is not yet known whether selumetinib works better in treating patients with NF1-associated low-grade glioma compared to standard therapy with carboplatin and vincristine.

Pheochromocytomas and paragangliomas are neural crest-derived tumors of the nervous system that are often inherited and genetically heterogeneous. Genetic screening is recommended for patients and their relatives, and can guide clinical decisions. However, a mutation is not found in all cases. The aims of this proposal are to: 1) to map gene(s) involved in pheochromocytoma, and 2) identify genotype-phenotype correlations in patients with pheochromocytoma/paraganglioma of various genetic origins.

Military service members admitted to inpatient psychiatry for self-injurious thoughts and behaviors (SITBs) represent an at-risk group for continued SITBs and rehospitalizations in the post-discharge period. However, there is an absence of evidence-based interventions designed to be delivered on inpatient psychiatric units to reduce the risk of post-discharge SITBs. To address this gap, the investigator's research group developed Written Exposure Therapy for Suicide Prevention (WET-SP), a brief, scalable, suicide-specific psychotherapy based on the written disclosure paradigm. Written disclosure, in which an individual writes about a personally stressful experience and the related thoughts and feelings, yields improvements across physical and psychiatric domains. Pilot data suggest that written exposure also yields reductions in SITBs. Yet, no study has adapted the written exposure paradigm specifically to target the amelioration of distress associated with suicidal crises and examined whether implementing WET-SP reduces the risk of subsequent SITBs and suicide-related hospitalizations. The primary objective of this randomized controlled trial (RCT) is to evaluate the efficacy of WET-SP, in reducing the incidence and severity of SITBs in active duty military service members following a psychiatric hospitalization due to suicidal ideation, suicide plans, or a suicide attempt. Secondary objectives are to evaluate a potential mechanism of change (i.e., decreases in thwarted belongingness [cf. social disconnectedness]) and moderator of outcomes (i.e., arc of narrative [cf. linguistical parameters of the written narratives generated during treatment]). Participants randomized to WET-SP + TAU will receive five sessions of WET-SP delivered by the study team during their psychiatric hospitalization plus treatment-as-usual (TAU). Participants randomized to TAU will receive daily contact and patient-centered care delivered by the acute psychiatric inpatient unit provider team (e.g., psychiatrists, therapists, case managers). TAU includes psychiatric assessment, initial stabilization, nurse case management, medication management, treatment of medical comorbidities, group and individual therapy, and discharge planning. Outcome assessments will be administered at pretreatment, posttreatment, and 10-, 20-, and 30-week follow-ups.

The purpose of this randomized pragmatic trial is to assess the effect of monthly booster contacts on long-term Brief Cognitive Behavioral Therapy for Chronic Pain (BCBT-CP) pain outcomes compared to BCBT-CP without a booster in 716 Military Health Systems (MHS) beneficiaries referred to a Behavioral Health Consultant (BHC) for pain management using BCBT-CP. Patients will be randomly assigned to receive either standard BCBT-CP (working with a BHC in the medical home clinic) or standard BCBT-CP with adjunctive monthly booster contacts. Additionally, patient participants and clinic providers and staff will be offered the opportunity to participate in separate post-treatment Focus Groups using a semi-structured interview format designed to assess the usability, ease of use, perceived effectiveness, helpfulness, and barriers to the pain management intervention. Patient participants will be assessed 3-, 6-, 12- and 18-Months following their first appointment for BCBT-CP.

This phase II/III trial compares the effect of adding chemotherapy before and after surgery versus after surgery alone (usual treatment) in treating patients with stage II-III gallbladder cancer. Chemotherapy drugs, such as gemcitabine and cisplatin, work in different ways to stop the growth of tumor cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Giving chemotherapy before surgery may make the tumor smaller; therefore, may reduce the extent of surgery. Additionally, it may make it easier for the surgeon to distinguish between normal and cancerous tissue. Giving chemotherapy after surgery may kill any remaining tumor cells. This study will determine whether giving chemotherapy before surgery increases the length of time before the cancer may return and whether it will increase a patient's life span compared to the usual approach.

The rapid growth rate and unique challenges as a new immigrant group call for a better understanding of the social and health needs of the older Asian Americans (AAs) population. Overwhelming numbers of AAs, a fast-growing first-generation immigrant group, suffer from type 2 diabetes (T2D) and its consequences of poorly controlled blood glucose. For the older AAs, there are higher prevalence rates, worse diabetes control, and higher rates of complications due to limited English proficiency and health literacy. Despite the evidence concerning the effects of dietary interventions on glycemic control by well-controlled feeding studies in mainstream Americans, a lack of clinical trials of culturally tailored interventions often imposes serious barriers to translate and implement such fruitful and innovative approaches in individuals from ethnic minority communities such as AAs. The proposed study will use a randomized, controlled design with a sample of 60 AAs aged 65 years or older. Metabolomics methodologies will be incorporated into this research to provide a global picture of metabolites' responses to personalized behavioral nutrition (PBN) intervention. The study results will obtain the necessary information to conduct a meaningful community-based clinical trial to test the effectiveness of PBN in improving dietary patterns and glycemic control in older AAs.

RYGB (roux-en-y gastric bypass) has been reported to reverse type 2 diabetes (T2DM) immediately after surgery before any significant weight loss. In addition, a growing number of patients have been recognized with life-threatening hyperinsulinemic hypoglycemia several years following their surgery. While the mechanisms by which RYGB improves glucose metabolism or alters islet cell function in patients after RYGB are not understood, recent studies suggest that increased secretion of GI hormones, primarily glucagon-like peptide 1 (GLP-1), as well as alteration in neural activity may contribute to enhanced insulin secretion in general, and to a greater extent in patients with hypoglycemia. The proposed research is designed to address the role of RYGB on insulin secretion by evaluating the contribution of stimulatory factors (neural and GI hormone) on islet cell function and the islet cell responsiveness to the physiologic stimulatory factors, in RYGB patients with and without hypoglycemia and non-operated controls.

This study examines the impact of social and genetic factors on outcomes in adolescent and young adult (AYA) cancer survivors of Hodgkin or non-Hodgkin lymphoma. Compared to both older adult and childhood cancer patients, AYAs with cancer experience different diagnoses and specific biological, clinical, psychological and social factors that affect their risks for post-treatment morbidity and premature death. Collecting samples of blood samples and health and treatment information from cancer survivors of Hodgkin or non-Hodgkin lymphoma may help doctors identify conditions that increase the likelihood of AYAs getting sick and dying after treatment of cancer and better understand how to address the needs of adolescent and young adult cancer survivors.

The goal of this randomized pilot trial is to assess the feasibility of administering a combination of 100mg intramuscular (IM) ketamine and Crisis Response Plan (a short psychosocial intervention) for patients with acute suicidality in the context of the Emergency Department setting. This study will assess a combination of a pharmacologic intervention and a psychosocial one. The pharmacologic intervention is a one-time dose of 100mg ketamine delivered intramuscularly (IM) while the patient is in the ED. The psychosocial intervention under study is a brief, patient-centered therapy which takes, on average, 30 minutes to administer. Both interventions will be administered only once. The main questions this study aims to answer are: - Determine if 100mg of IM ketamine and Crisis Response Plan in combination results in greater short-term reductions in suicidal ideation in adult patients who report acutely elevated suicide risk during an ED visit. - Examine potential weight-based dose response differences in the reductions in suicidal ideation to determine if future treatment protocols with IM ketamine may benefit from weight-based dosing.
