This 3-year study is a trial of cognitive behavioral therapy (CBT), with or without oxytocin (OT) augmentation, in young adults with autism spectrum disorders. Participants will be randomly assigned to receive either a social skills-focused CBT intervention or a stress management/relaxation training CBT intervention. Participants will also be randomized to receive either a) intranasal oxytocin or b) a placebo drug, prior to the psychotherapy. The design of the study will enable examination of the efficacy of CBT for young adults with autism spectrum disorders. The design of the study will also allow examination of whether oxytocin enhances the efficacy of CBT. The investigators will perform functional (fMRI) and structural (MRI) imaging with all participants prior to treatment. This will enable examination of the relations between measures of brain function and structure, and improvements in target symptoms over the course of treatment. The aim is to discover whether there are neural characteristics that can identify which participants with autism spectrum disorders are most likely to respond to CBT interventions and/or oxytocin treatment.

The purpose of this study is to explore the effects of synthetic gonadotropin-releasing hormone (GnRH) upon the pituitary and ovaries of women with infertility. Women diagnosed with GnRH deficiency, hypothalamic amenorrhea or acquired hypogonadic hypogonadism, will participate in this study. It is hoped that administration of GnRH will lead to proper stimulation of the pituitary gland and to normal ovulation and menstruation. **WE ARE CURRENTLY RECRUITING ONLY WOMEN WITH A DIAGNOSIS OF IDIOPATHIC HYPOGONADIC HYPOGONADISM (IHH)** Pulsatile GnRH has been approved by the FDA for use in women with primary amenorrhea due to complete GnRH deficiency. The overall goals of this protocol are to continue to use pulsatile GnRH in GnRH-deficient and other anovulatory women for ovulation induction and to examine specific physiologic hypotheses, which can only be addressed in this patient population.

The objective of this study is to determine the level of symptoms, functional disability, and changes in quality of life that breast cancer patients experience from changes in their arm(s) during and after treatment for breast cancer. These problems are often associated with transient or chronic lymphedema, numbness, reduced shoulder flexibility, and an altered ability to use the arm for functional activities of daily living. The goal of this study is to collect data to support the hypothesis that swelling and other impairments in the upper extremities, causes a significant level of symptoms, functional disability and diminished quality of life for patients. Furthermore the investigators hope to evaluate how symptoms in the upper extremity (such as decreased functionality, sensory changes, pain or stiffness) are related to early, low volume lymphedema.

The purpose of this study is to see if repeat bacillus Calmette-Guérin (BCG) vaccinations can confer a beneficial immune and metabolic effect on Type 1 diabetes. Published Phase I data on repeat BCG vaccinations in long term diabetics showed specific death of some of the disease causing bad white blood cells and also showed a short and small pancreas effect of restored insulin secretion. In this Phase II study, the investigators will attempt to vaccinate more frequently to see if these desirable effects can be more sustained. Eligible volunteers will either be vaccinated with BCG in a repeat fashion over a period of four years or receive a placebo treatment. The investigators hypothesize that each BCG vaccination will eliminate more and more of the disease causing white blood cells that could offer relief to the pancreas for increased survival and restoration of insulin secretion from the pancreas.

The main purpose of this study is to examine the outcome of a combined bone marrow and kidney transplant from a partially matched related (haploidentical or "haplo") donor. This is a pilot study, you are being asked to participate because you have a blood disorder and kidney disease. The aim of the combined transplant is to treat both your underlying blood disorder and kidney disease. We expect to have about 10 people participate in this study. Additionally, because the same person who is donating the kidney will also be donating the bone marrow, there may be a smaller chance of kidney rejection and less need for long-term use of anti-rejection drugs. Traditionally, very strong cancer treatment drugs (chemotherapy) and radiation are used to prepare a subject's body for bone marrow transplant. This is associated with a high risk for serious complications, even in subjects without kidney disease. This therapy can be toxic to the liver, lungs, mucous membranes, and intestines. Additionally, it is believed that standard therapy may be associated with a higher risk of a complication called graft versus host disease (GVHD) where the new donor cells attack the recipient's normal body. Recently, less intense chemotherapy and radiation regimens have been employed (these are called reduced intensity regimens) which cause less injury and GVHD to patients, and thus, have allowed older and less healthy patients to undergo bone marrow transplant. In this study, a reduced intensity regimen of chemotherapy and radiation will be used with the intent of producing fewer toxicities than standard therapy. Typical therapy following a standard kidney transplant includes multiple lifelong medications that aim to prevent the recipient's body from attacking or rejecting the donated kidney. These are called immunosuppressant drugs and they work by "quieting" the recipient's immune system to allow the donated kidney to function properly. One goal in our study is to decrease the duration you will need to be on immunosuppressant drugs following your kidney transplant as the bone marrow transplant will provide you with the donor's immune system which should not attack the donor kidney.

: Stages III and IV serum ovarian cancer are the most lethal of all gynecologic cancers; however, some advanced-stage ovarian cancer patients are long-term survivors. These patients may provide the key to long-term survival and bring hope to all women with Stages III and IV ovarian cancer. There is no meaningful explanation of why some patients with ovarian cancer become long-term survivors and what their quality of life is long after their initial diagnosis. This research project will specifically determine molecular features within tumors along with genetic, quality of life, and lifestyle features that predict for long-term survival for patients with Stages III and IV ovarian cancer. It will bring together sophisticated molecular techniques, researchers with longstanding interest, a wide spectrum of consumer advocates (a number being long-term survivors), and quality of life experts to analyze the most carefully maintained patient database in the world—the Gynecologic Oncology Group database. We anticipate the results from this project will identify specific biochemical pathways and genetic features associated with long-term survival that can be used to improve the treatment, survival, and survivorship of patients with this disease. There is clearly something unique among patients who survive Stage III or IV ovarian cancer long term, and we believe that when we understand what this is, we can increase the number of long- and longer-term survivors.

The purpose of the study is to explore the way in which gonadotropins (pituitary hormones) are released into the body. The knowledge acquired in this study will be used for the diagnosis and treatment of reproductive endocrine disorders. We seek to investigate the baseline characteristics of the GnRH-induced gonadotropin pulsations of patients with the following diagnoses: - Hypothalamic Amenorrhea (HA) - Idiopathic hypogonadotropic hypogonadism (IHH) - Polycystic ovarian disease (PCOD) - Acquired hypogonadotropic hypogonadism (AHH) - Premature Ovarian Failure (POF) **WE ARE CURRENTLY RECRUITING ONLY SUBJECTS WITH A DIAGNOSIS OF IHH.** This has been an extremely productive and pivotal protocol in the studies of female reproductive physiology and pathophysiology and continues to be critical for defining the neuroendocrine abnormalities in patients with reproductive disorders. In some cases, it is also helpful in the planning of subsequent therapy if so desired. It is important to note that minors have been included in this protocol, as many patients are extremely anxious to know more about their neuroendocrine disorder. With minors who would like to know if their disorder is correctable, this protocol may be followed up with administration of pulsatile gonadotropin-releasing hormone (GnRH).
