Interstitial cystitis/bladder pain syndrome (IC/BPS) is a severe pain condition affecting 3-8 million people in the United States lacking treatments that work. Emotional suffering is common in IC/BPS and known to make physical symptoms worse, and studies show patient sub-groups respond differently to treatment. By creating and testing a psychosocial intervention specific to IC/BPS, we will learn if this intervention improves patient wellness, who the intervention works best for, and how the body's pain processing influences outcomes.

Deficits in cognitive control are core features of late-life depression, contributing both to emotion dysregulation and problems with inhibiting irrelevant information, conflict detection, and working memory. Clinically characterized as executive dysfunction, these deficits are associated with poor response to antidepressants and higher levels of disability. Improvement of cognitive control network (CCN) dysfunction may benefit both mood and cognitive performance, however no current pharmacotherapy improves CCN deficits in LLD. Supported by pilot data, Investigators propose that nicotine acetylcholine receptor agonists enhance CCN function and resultantly improve mood and cognitive performance in late-life depression. The objective of this initial R61-phase trial is to first determine whether transdermal nicotine enhances CCN neural activity in an exposure-dependent fashion during an emotional response inhibition task (the emotional Stroop task). Investigator's approach for the R61 phase is to examine in 36 older adults with Major Depressive Disorder whether transdermal nicotine patches enhance CCN activity over 12 weeks as measured during fMRI with the emotional Stroop task while measuring nicotine and nicotine metabolite levels. Transdermal nicotine has a mechanism of action that is distinct from current antidepressants, potentially making it a potentially important antidepressant augmentation agent. If hypotheses are correct, as patches are commercially available, this approach could be rapidly moved into definitive studies and may have applicability to other psychiatric disorders characterized by CCN dysfunction.

Neurofibromatosis Type 1 (NF1) is a common genetic disorder that is associated with a four times greater risk of learning disabilities, including reading disabilities, and a deficiency of neurofibromin - a protein important in a signaling pathway that regulates learning and memory. Our previous work (NS49096) demonstrated that school-age children with NF+RD can respond to standard phonologically-based reading tutoring originally developed to treat reading disability in the general population. Combining our work with that by other researchers suggesting that a medication (Lovastatin) may counteract the effects of the deficient neurofibromin, and possibly ameliorate learning disabilities in NF1, the investigator propose to examine the synergistic effects of medication plus reading tutoring.

A phenome-wide association study (PheWAS) identified an association between a loss of function variant in the human alpha 2B adrenergic receptor gene and trigeminal nerve disorders. Guanfacine is the oldest alpha-2 adrenergic agonist in clinical use and is approved for hypertension and attention deficit hyperactivity disorder. We hypothesize that guanfacine will be an effective adjunct to lidocaine for the treatment of neuropathic pain by enhancing and prolonging pain relief due to its activation of alpha-2 adrenergic receptors. The objectives of the study will be to evaluate the efficacy and safety of guanfacine in combination with lidocaine for trigeminal nerve block procedures for pain management in trigeminal neuralgia patients. This study will evaluate the efficacy of guanfacine in reducing acute pain and extending duration of pain relief when delivered in combination with lidocaine as a trigeminal nerve block, measured by Visual Analog Scale (VAS) data collected at specific time points after each injection.

The overall purpose of this study is to learn more about the metabolic effects of angiotensin-(1-7) in the insulin resistant state associated with obesity. Pharmacologic approaches to increase angiotensin-(1-7) levels or its actions are currently in development for treatment of metabolic-related diseases such as obesity and type II diabetes, based on findings from animal studies. It is unclear if this peptide contributes to the regulation of metabolism in humans. The investigators will test if angiotensin-(1-7) infusion can improve insulin sensitivity measured by hyperinsulinemic-euglycemic clamp methods in individuals with obesity and insulin resistance. The investigators will also examine for changes in blood pressure and related hemodynamic and hormonal changes following angiotensin-(1-7) infusion.

Rationale: The accrual of data from the laboratory and from epidemiologic and prevention trials has improved the understanding of the etiology and pathogenesis of type 1 diabetes mellitus (T1DM). Genetic and immunologic factors play a key role in the development of T1DM, and characterization of the early metabolic abnormalities in T1DM is steadily increasing. However, information regarding the natural history of T1DM remains incomplete. The TrialNet Natural History Study of the Development of T1DM (Pathway to Prevention Study) has been designed to clarify this picture, and in so doing, will contribute to the development and implementation of studies aimed at prevention of and early treatment in T1DM. Purpose: TrialNet is an international network dedicated to the study, prevention, and early treatment of type 1 diabetes. TrialNet sites are located throughout the United States, Canada, Finland, United Kingdom, Italy, Germany, Sweden, Australia, and New Zealand. TrialNet is dedicated to testing new approaches to the prevention of and early intervention for type 1 diabetes. The goal of the TrialNet Natural History Study of the Development of Type 1 Diabetes is to enhance our understanding of the demographic, immunologic, and metabolic characteristics of individuals at risk for developing type 1 diabetes. The Natural History Study will screen relatives of people with type 1 diabetes to identify those at risk for developing the disease. Relatives of people with type 1 diabetes have about a 5% percent chance of being positive for the antibodies associated with diabetes. TrialNet will identify adults and children at risk for developing diabetes by testing for the presence of these antibodies in the blood. A positive antibody test is an early indication that damage to insulin-secreting cells may have begun. If this test is positive, additional testing will be offered to determine the likelihood that a person may develop diabetes. Individuals with antibodies will be offered the opportunity for further testing to determine their risk of developing diabetes over the next 5 years and to receive close monitoring for the development of diabetes.

Mothers of adolescents with type 1 diabetes experience high levels of depressive symptoms, which impair their ability to monitor and manage diabetes treatment effectively. Further, maternal depressive symptoms are one of the strongest predictors of negative outcomes in adolescents, including deteriorating glycemic control, problems with adherence, poorer quality of life, and greater risk for depression. Given that adolescents are a high-risk population for suboptimal glycemic control - with only 17% meeting treatment goals - there is a critical need for novel interventions to improve outcomes in adolescents with T1D. Yet, previous behavioral interventions for youth with diabetes have had only modest effects on glycemic control, and none have directly targeted maternal depressive symptoms. Building on effective interventions to treat depression in adults, and our own pilot work in this population, the proposed study will use a rigorous approach to evaluate the efficacy of a cognitive-behavioral intervention for mothers of adolescents with type 1 diabetes to promote the use of adaptive coping strategies and positive parenting practices. The aims of this study are to: 1) evaluate the effects of the Communication & Coping intervention on diabetes-related outcomes; 2) evaluate the effects of the Communication & Coping intervention on psychosocial outcomes; and 3) explore the differential impact of the intervention across demographic factors. Mothers who are randomized to the Communication & Coping Intervention will receive individual cognitive-behavioral therapy sessions by phone, as well as access to a Facebook group to augment the material covered in calls and provide social support. Mothers randomized to the Attention Control condition will receive educational materials and phone check-ins, as well as a Facebook group with educational posts. Adolescents and their mothers will be assessed at baseline and again post-intervention, at 3 months, 6 months, and 12 months.

Late-Life Depression (LLD), or depression in older adults, often presents with motivational deficits, deficits in performance in cognitive domains including processing speed and executive dysfunction, and mobility impairments. This triad of findings implicate dopaminergic dysfunction as a core pathophysiologic feature in depression, and may contribute to cognitive decline and motor disability. Normal aging results in brain-wide dopamine declines, decreased D1/D2 receptor density, and loss of dopamine transporters. Although brain changes associated with depression and aging converge on dopamine circuits, the specific disturbances in LLD and how responsive the system is to modulation remain unclear. In this collaborative study between Columbia University /New York State Psychiatric Institute and Vanderbilt University Medical Center, investigators are testing integrative model that aging, in concert with pro-inflammatory shifts, decreases dopamine signaling. These signally changes affects behaviors supported by these circuits, in the context of age-associated cortical atrophy and ischemic microvascular changes, resulting in variable LLD phenotypes. Investigators propose a primary pathway where dopaminergic dysfunction in depressed elders contributes to slowed processing speed and mobility impairments that increase the effort cost associated with voluntary behavior. The central hypothesis of this study is that late-life depression is characterized by dysfunction in the dopamine system and, by enhancing dopamine functioning in the brain. By improving cognitive and motor slowing, administration of carbidopa/levodopa (L-DOPA) will improve depressive symptoms.

The primary objective is to evaluate the overarching hypothesis that obese and black individuals have relatively lower circulating natriuretic peptide levels compared with lean and white individuals. Conventional clinical assays for measurement of circulating natriuretic peptides display substantial overlap, precluding determination of the basis of the relative natriuretic peptide deficiency previously observed in these groups. We will study lean or obese, black or white, healthy adult subjects with intravenous (IV) saline infusion as a stimulus for natriuretic peptide production and release.
