Background: Systemic lupus erythematosus (SLE) is a disease that affects females nine times more often than males. People with SLE are often treated with cyclophosphamide (CYC). But CYC can damage a woman s ovaries; it may cause infertility. A drug called GnRHa is sometimes given to protect the ovaries during CYC therapy. But no one really knows how effective GnRHa treatment is. This natural history survey will compare women who received GnRHa during CYC therapy with those who did not. Objective: To find out whether GnRHa can help protect women s ovaries during CYC. Eligibility: Women under age 40 years starting CYC treatment with or without GnRHa. Design: This study will do 2 things: It will conduct patient surveys. It will collect data from medical records. Participants will complete a one-time survey. They will answer questions about their menstrual cycle. They will be asked about their history of pregnancy or infertility. Participants can take the survey in 4 ways: On paper, sent through the mail. Online, in a secure web page managed by the NIH. By phone. In person, during a routine visit to the NIH clinic. The survey will take about 30 minutes. Participants medical records will be reviewed. Researchers will look for data about the participants SLE disease. This may include their symptoms and the results of their blood tests. It may also include the details of prior treatments. Researchers will also collect data about participants reproductive history. This may include their personal or family history of infertility. It may include any fertility treatments and any sexually transmitted infections.
The objective is to evaluate the resultant thickness of the FS200 created LASIK flap compared to plan at the surgical visit.
The AIRB research team will compare the use and effectiveness of each intervention (Mind the Gap, Remaking Recess and Self Determined Learning Model of Instruction) with and without the addition of our implementation strategy, UNITED. In all groups, the research team will train community practitioners using remote delivery of professional development modules specific to the intervention and active coaching as dictated by the intervention procedures. The research team will pair UNITED with three interventions that cover the ages of early childhood, childhood, and adolescence. These include Mind the Gap (MTG), a family navigation intervention for children newly diagnosed under age 8, Remaking Recess (RR), a school-based social/peer engagement intervention for children ages 5-12, and Self-Determination Learning Model of Instruction (SDMLI), a self-advocacy intervention for adolescents (13-22 years; 22 is the upper age limit of high school for individuals with disabilities). For the SDLMI, school personnel will be trained to work with adolescents with ASD using the SDLMI model. This model will help students with ASD set their own goals and help attain them. The total time commitment for the school personnel is 1 school year (2 semesters) for about 47 hours. The total time commitment for the parent of the student with ASD is about 1 hour (sign consent/fill out demographic survey). The total time commitment for the student with ASD is 1 school year (2 semesters) for about 25.25 hours.
Subjects with resectable melanoma will receive neoadjuvant nivolumab followed by surgical resection. Post-operatively, subjects will receive open-label treatment with up to 1 year of adjuvant nivolumab or ipilimumab plus nivolumab as determined by pathologic response at the time of resection.
The Scientific Premise of this study is that the high level of obesity displayed by African American (AA) women is due to the ability to secrete large amounts of insulin when sugary foods are consumed. When AA women eat a diet rich in starchy or sugary food (a "high-glycemic" diet that stimulates insulin secretion), the food that is eaten is stored as fat rather than being burned as fuel. The investigators previous research has suggested that AA women have an easier time losing weight and keeping it off when eating a low-glycemic diet. The proposed study will be the first randomized clinical trial to test the effect of high and low glycemic diets for weight loss and weight-loss-maintenance in obese AA women.
This proposed follow-up study aims to recruit participants from the original BioImage cohort for a one-time follow-up examination. The repeat ultrasound scan of the carotid arteries will provide information on the natural history of carotid atherosclerosis and factors that contribute to plaque progression. Renewal of the HIPAA authorization will also be sought for 5 years to continue to monitor claims and other information for major cardiovascular events, other outcomes and healthcare utilization.
The effect of tinted filters and illumination on the visual performance of patients with low vision (i.e., individuals with reduced vision that is uncorrectable with glasses, surgery or treatments) has been a topic of research and discussion for many years, yet there is no current consensus or practice standard for the evaluation and recommendation of colored filters and/or illumination intensity. Anecdotally, there have been many subjective reports of improvement in visual function and comfort with the use of tinted lenses. Previous studies have attempted to elucidate the subjective improvements observed using vision tests, such as visual acuity and contrast sensitivity, and the findings have been inconsistent. Traditionally, filters and optimal illumination are prescribed clinically through a trial and error method, which involves trying various filters and lamps haphazardly to determine which if any are preferred by the patient. The investigators are proposing to evaluate whether the illumination and filters chosen in office by participants using a new assessment tool the LuxIQ/2 translate to overall patient comfort and improved speed, accuracy and print size while reading, and to evaluate whether participants have the same illumination and colored filter preference determined by the LuxIQ/2 in a clinical office setting and in their home environment. The investigators will evaluate whether participants prefer lighting determined by the new assessment tool the LuxIQ/2 in comparison to lighting determined by the OttLite Cobra in office.
Comparing renal outcomes based on a Mean Arterail Pressure (MAP) of 65-7085mmhg versus a MAP of greater than or equal to 85mmhg
The purpose of this study is to determine the number of Medication Treatment Modifications (MTMs) made by the clinician at every visit when antipsychotic medication plasma levels (AMPL) results are available compared to when AMPL results are not available.
This study is a Phase III, randomised, open label, multi-centre study assessing the efficacy and safety of MEDI4736 (durvalumab) versus Standard of Care in NSCLC patients with PD-L1 positive tumours and the combination of MEDI4736 (durvalumab) plus tremelimumab (MEDI4736+treme) versus Standard of Care in NSCLC patients with PD-L1-negative tumours in the treatment of male and female patients with locally advanced or metastatic NSCLC (Stage IIIB-IV), who have received at least 2 prior systemic treatment regimens including 1 platinum-based chemotherapy regimen for NSCLC. Patients with known EGFR (Epidermal growth factor receptor) tyrosine kinase (TK) activating mutations and anaplastic lymphoma kinase (ALK) rearrangements are not eligible for the study (prospective testing is not planned within this study). The Standard of Care options are: an EGFR tyrosine kinase inhibitor (erlotinib \[TARCEVA®\]), gemcitabine or vinorelbine (NAVELBINE®)
Data from subjects who had previously been dosed with Flutemetamol (18F) Injection and imaged in Study GE-067-007, and who died on or before 10 June 2013, will be analyzed. The PET brain images previously obtained in Study GE-067-007 will be interpreted visually in randomized by 5 independent readers who are blinded to all other subject information, and the images will be classified as abnormal (positive for abnormal neuritic plaque density) or normal (negative for abnormal neuritic plaque density). The numbers of images in each category will be used to calculate sensitivity and specificity.
The purpose of this study is to determine whether adding primidone will improve the metabolism of clopidogrel thereby increasing metabolite levels within the blood stream and platelet response to clopidogrel in patients who were previously found to lack adequate response to clopidogrel. This information could help overcome clopidogrel resistance in patients who are at risk for stroke or transient ischemic attack (TIA).
This is a double-blind study with respect to the diluents used, with patients known to be allergic to the specific allergen tested. Three study sites will be involved, each testing one allergen (Cat, Mite, Timothy grass pollen). Subjects who are known to be allergic to the allergen in question will be tested with serial three-fold dilutions to determine the ID 50 and relative extract potency using the method described by Turkeltaub.
Pilot prospective two group observational study to create a model of the carotid plaque composition based on ultrasonic backscattered signals and select clinical data.
Atrial fibrillation (AF), the most common sustained heart rhythm disorder, is becoming increasingly prevalent in the Western world. The number of people with AF in the United States is projected to roughly double by the year 2050, to an estimated 6-12 million. For many patients with AF, rate control with atrioventricular (AV) node blockers is a widely accepted therapeutic strategy. These agents control heart rate, thus preventing symptoms and systolic heart failure associated with tachycardia due to a rapid ventricular response to AF. Beta-blockers are widely accepted as first line agents for rate control in AF, especially when patients have concomitant hypertension (HTN), coronary artery disease, cardiomyopathies, or heart failure (HF). As a class, beta-blockers are among the most commonly prescribed cardiovascular medications. Among patients with AF treated with beta-blockers, the heart rate (HR) response varies substantially. Sometimes, adequate rate control can be achieved by titration of the beta-blocker dose; but frequently, additional AV nodal blockers and/or digoxin are necessary. In some cases, adequate rate control cannot be achieved even with the simultaneous use of multiple AV nodal blockers, necessitating mechanical ablation of the AV node and permanent pacemaker implantation. Patient-specific variables that influence the response to beta-blockers include comorbid conditions, weight, age, and level of physical activity. Ethnic differences in the response to beta-blockers for the treatment of HTN and HF are well-described. However, the contribution of genetic variants to beta-blocker efficacy in AF is unknown. We propose to study whether the ADRB1 Gly389Asp SNP reduces response to beta-blockade in subjects with permanent AF.
The aim of this study is to determine the yield of 3 weeks outpatient mobile cardiac monitoring for detection of atrial fibrillation in patients with history of stroke of known cause.
The purpose of the Heart Failure and Risk of re-Admissions Determined by Abnormal REVEAL Parameters (HF RADAR) study is to evaluate the ability of cardiac rhythm (Cardiac Compass) data to predict future cardiac events in heart failure (HF) patients recently discharged after a hospitalization for heart failure who have or plan to have a implanted loop recorder (ILR), specifically, the Reveal XT device. The study will enroll 40 HF patients (with LV function ≥ 40%) admitted to an acute care facility (observation status or hospital stay) for heart failure who either have a Reveal XT device in place or plan to have the ILR device inserted for clinical indication within 14 days of discharge from the hospitalization. HF patients will be followed for 6 months. Device date will be captured during normal clinic visits and at 6 months.
The purpose of this study is to test whether the incidence of sore throat and other tracheal co-morbidities such as dysphagia and hoarseness can be lessened by use of a cuff manometer at the beginning of surgery to inflate to the proper pressure compared to the standard technique. The investigators hypothesis is that inflation of the endotracheal balloon using a cuff manometer immediately after intubation will reduce the incidence of sore throat and other tracheal co-morbidities.
The primary objective: \*To measure the difference in the number of Ranibizumab therapies needed in 12 months in the Posterior Vitreous Detachment (PVD) positive and Posterior Vitreous Detachment (PVD) negative group. Secondary Objective: * To measure the mean change in visual acuity from Baseline to Month 12. * To measure the mean change in central retinal thickness per OCT from Baseline to Month 12
Diagnosis of diffuse intrinsic pontine glioma (DIPG) for decades has relied on imaging studies and clinical findings. Histologic confirmation has been absent with surgical biopsy of brainstem tumors not believed to have acceptable safety. The prognosis of DIPG has remained quite poor and novel therapeutic strategies are needed. This DIPG Biology and Treatment Study (DIPG-BATS) study incorporates a surgical biopsy at presentation using strict preoperative neurosurgical planning and stratifies participants to receive FDA-approved agents chosen on the basis of specific biologic targets. This is the first prospective national clinical trial to examine the feasibility and safety of incorporating surgical biopsy into potential treatment strategies for children with DIPG.
To evaluate tear film stability of a market lubricant therapeutic eye drop versus saline when using Evaporometry and Interferometry in patients with a diagnosis of Keratoconjunctivitis Sicca (KCS). The purpose of this research is to evaluate evaporative parameters and tear film quality when using Systane lubricating eye drops versus saline in the eyes of dry eye patients at pre-instillation and at 30 and 60 minutes post instillation of drop(s).
This is a single-center, open-label, parallel group study designed to investigate the effect of CYP3A induction and inhibition following multiple doses of phenytoin (Part A) and itraconazole (Part B), respectively, on the pharmacokinetics of sonrotoclax in healthy volunteers.
Our study will be a prospective observational study of all patients in the Norton Children's Hospital NICU (Neonatal Intensive Care Unit) who undergo a transcatheter PDA occlusion or medical closure of PDA to compare the two populations regarding changes in organ perfusion determined by using NIRS monitoring to follow the regional saturation of oxygen (rSO2) of the cerebral and renal regions. We suspect that medical treatment will have no significant change in rSO2 as described in previous literature. We also suspect that transcatheter occlusion will have minimal effects on rSO2 and be comparable to medical therapy.
The purpose of this study is to learn more about how well a questionnaire about food intake works. The study team will compare questionnaire responses to several other measurements of food intake. There is a special emphasis on fruit and vegetable intake.
