This trial studies how well paclitaxel, trastuzumab, and pertuzumab work in eliminating further chemotherapy after surgery in patients with HER2-positive stage II-IIIa breast cancer who have no cancer remaining at surgery (either in the breast or underarm lymph nodes) after pre-operative chemotherapy and HER2-targeted therapy. Drugs used in chemotherapy, such as paclitaxel, 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. Trastuzumab and pertuzumab are both a form of "targeted therapy" because they work by attaching themselves to specific molecules (receptors) on the surface of tumor cells, known as HER2 receptors. When these drugs attach to HER2 receptors, the signals that tell the cells to grow are blocked and the tumor cell may be marked for destruction by the body's immune system. Giving paclitaxel, trastuzumab, and pertuzumab may enable fewer chemotherapy drugs to be given without compromising patient outcomes compared to the usual treatment.

Despite the advent of safer HIV therapies, high levels of markers of systemic inflammation and increased cardiovascular risk threaten the well-being of individuals living with HIV and present a significant challenge for HIV providers. These risks may be accentuated in HIV-infected individuals who are active intravenous drug users (IVDU); however, this population has been specifically excluded from prior studies assessing immune activation and cardiovascular risk in people living with HIV. In this study, the investigators will specifically target HIV-infected participants who are active IVDU, and co-enroll a control group of HIV-infected participants who never used IV drugs. The investigators will study the specific alterations in immune activation and several mechanisms felt to be potential drivers of immune activation outside of the IVDU population, namely gut integrity alteration, microbial translocation, and oxidized lipids. The investigators will also study the effect of IVDU on markers of arterial inflammation and vascular function. Importantly, the investigators will study the reversibility of immune activation, gut dysfunction, and cardiovascular markers after cessation of IVDU, and to that effect, compare strategies for IVDU cessation-buprenorphine/naloxone versus methadone or vivitrol maintenance treatment.

This phase II/III trial studies the side effects of nivolumab and ipilimumab when given together with or without sargramostim and to see how well they work in treating patients with stage III-IV melanoma that cannot be removed by surgery (unresectable). Immunotherapy with monoclonal antibodies, such as ipilimumab and nivolumab, may help the body's immune system attack the cancer, and may interfere with the ability of tumor cells to grow and spread. Colony-stimulating factors, such as sargramostim, may increase the production of white blood cells. It is not yet known whether nivolumab and ipilimumab are more effective with or without sargramostim in treating patients with melanoma.

Gastroesophageal reflux disease related symptoms are reported by 10-20% of the adult population and of those 50-75% report symptoms during sleep time. The prevalence of nocturnal GERD (nGERD) is estimated to be about 25% in general population. nGERD causes sleep fragmentation, difficulty falling asleep, daytime sleepiness, reduced work productivity and decreased quality of life. Additionally, nighttime gastroesophageal reflux has been associated with increased risk of GERD-related complications such as severe erosive esophagitis, peptic stricture, esophageal ulcer, Barrett's esophagus, and esophageal adenocarcinoma. Furthermore, nocturnal gastroesophageal reflux has been noted to be associated with atypical and extra-esophageal manifestations as well as sleep disturbances. Overall, patients with nocturnal gastroesophageal reflux are more likely to develop a more severe form of GERD. The mainstay of treatment of nighttime gastroesophageal reflux is a proton pump inhibitor (PPI). However, nighttime heartburn is the most common breakthrough symptom in patients with GERD, who failed PPI treatment. Other important therapies for nighttime GERD include, lifestyle modifications, such as elevating the head of the bed, avoiding eating at least three hours before bedtime, maintaining appropriate sleep hygiene and avoiding the right decubitus position. Elevating the upper torso by raising the head of the bed and avoiding the right-lateral decubitus position have been shown to improve nocturnal symptoms. Several studies have shown that sleeping in the left decubitus position decrease esophageal acid exposure by reducing 13-76% of the reflux episodes. Studies have shown that the right decubitus position increases the rate of transient lower esophageal sphincter relaxations (TLESRs) accompanied by acid reflux, as compared with the left recumbent position. Moreover, maintaining the left lateral recumbent position, reduced by 87% esophageal acid exposure and nocturnal symptoms. LEFT is a novel electronic wearable device that was developed as a sleep position therapy for patients who suffer from nighttime gastroesophageal reflux symptoms. It is simple, noninvasive and low-cost technology which has been developed by Side Sleep Technologies B.V. Singel, Amesterdam, The Netherland. This technology is designed to train patients to sleep on their left side by a gentle vibration signal once it detects that they are sleeping on their back or right side. Thus, this technique may reduce gastroesophageal reflux and thus provides relief of heartburn and regurgitation during sleep time. The purpose of this study is to determine the usefulness of positional therapy, using the LEFT device, as a nonmedical tool to control GERD-related nocturnal symptoms.

This randomized phase III trial studies radiation therapy and cisplatin with triapine to see how well they work compared to the standard radiation therapy and cisplatin alone in treating patients with newly diagnosed stage IB2, II, or IIIB-IVA cervical cancer or stage II-IVA vaginal cancer. Radiation therapy uses high energy protons to kill tumor cells and shrink tumors. Drugs used in chemotherapy, such as 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. Triapine may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. It is not yet known whether radiation therapy and cisplatin are more effective with triapine in treating cervical or vaginal cancer.

Minimal change disease (MCD), focal segmental glomerulosclerosis (FSGS), and Membranous nephropathy (MN), generate an enormous individual and societal financial burden, accounting for approximately 12% of prevalent end stage renal disease (ESRD) cases (2005) at an annual cost in the US of more than $3 billion. However, the clinical classification of these diseases is widely believed to be inadequate by the scientific community. Given the poor understanding of MCD/FSGS and MN biology, it is not surprising that the available therapies are imperfect. The therapies lack a clear biological basis, and as many families have experienced, they are often not beneficial, and in fact may be significantly toxic. Given these observations, it is essential that research be conducted that address these serious obstacles to effectively caring for patients. In response to a request for applications by the National Institutes of Health, Office of Rare Diseases (NIH, ORD) for the creation of Rare Disease Clinical Research Consortia, a number of affiliated universities joined together with The NephCure Foundation the NIDDK, the ORDR, and the University of Michigan in collaboration towards the establishment of a Nephrotic Syndrome (NS) Rare Diseases Clinical Research Consortium. Through this consortium the investigators hope to understand the fundamental biology of these rare diseases and aim to bank long-term observational data and corresponding biological specimens for researchers to access and further enrich.

This is a study investigating the best way to treat diabetic ketoacidosis (DKA) with intravenous (IV) fluids in the hospital. The purpose of this study is to determine whether the "two bag" system of administering IV fluids for the treatment of adults with DKA leads to a shorter time requiring intravenous insulin (a shorter time to anion gap closure), when compared to usual care the traditional "one bag" system of IV fluids. Participants will be assigned randomly to either the usual care group or the "two bag" system group. Based on studies performed in the past, the investigators predict that patients treated with the two bag system of IV fluids for DKA will have a significantly shorter time requiring treatment with intravenous insulin when compared to the traditional one bag system.
