Filter by:The primary objective of the clinical trial portion of this study is to assess whether an individualized dietary plan based on a commercial food sensitivity assay provides specific benefit in a randomized controlled trial in adults with irritable bowel syndrome (IBS).
Hypothesis: the effectiveness of treatment of Pompe disease with rhGAA enzyme replacement therapy (ERT) is limited at least in part because patients develop antibodies against the provided rhGAA enzyme. Treatment with Zavesca® prior to infusion may dampen or eliminate the anti-rhGAA immune response in patients receiving ERT, thereby allowing for greater ERT efficacy. Treatment with Zavesca® before a enzyme replacement therapy (ERT) may decrease the severity of, or eliminate infusion associated reactions (IAR) in people with Pompe Disease receiving ERT.
The aim of the intervention is to examine the effect of a combination of the two bacterial strains BB-12 and LGG, provided for 6 month, on the prevalence of infections and allergic manifestations in small children, and how a combination of BB-12 and LGG affects the immune system, gastrointestinal tract and the microbiota. Children are enrolled during 2 winter seasons.
Purpose: This study will evaluate a new ultrasound imaging technology called acoustic angiography. Acoustic angiography uses an ultrasound contrast agent, already FDA approved for use in cardiology, to enhance imaging of blood vessels. Since acoustic angiography uses ultrasound, and not x-rays, the patient is not exposed to ionizing radiation, unlike traditional angiography and mammography. Specific goals will be to evaluate the quality of the images provided by acoustic angiography in the human breast, and furthermore to evaluate whether or not acoustic angiography provides additional diagnostic information over traditional ultrasound which could provide an improvement in assessing breast lesions. Specifically, this additional diagnostic information will hopefully enable us to reduce false positive tests and discriminate lethal cancers from non-lethal disease. Participants: The investigators are recruiting 60 patients from the UNC Breast Clinic who are undergoing core needle biopsy or surgical biopsy (BIRADS 4 and 5 breast lesions). Procedures (methods): Acoustic Angiography imaging will be performed in conjunction with standard diagnostic imaging, including b-mode ultrasound . Then, a reader study will be conducted to compare these modalities. Finally, the images will be analyzed with image processing techniques to determine quantitative metrics exhibited by the blood vessel morphology in the images. These metrics will be utilized to develop a "malignancy score" equation to predict malignancy of a lesion.
The French cooperative group GINECO proposes to implement an observational study to describe a real situation, in daily practice tolerance and methods of administration of trabectedin (Yondelis®)-Pegylated liposomal doxorubicin(Caelyx)®, in ovarian platinum sensitive cancer relapse.
This is a pilot trial in cat allergic participants, designed to compare allergic responses in each participant to a specific allergen by two methods of exposure. The methods of exposure to be used are: the environment exposure chamber (EEC) and nasal allergen challenge (NAC). Potential participants will be screened for evidence of cat allergy. Participants with a range of allergic sensitivities to cat allergen will be enrolled. To help ensure some breadth in the level of allergic sensitivity among participants, individuals with both high and low exposures to cat allergens in their daily lives will be enrolled.
The goal of this clinical research study is learn if varenicline or the nicotine patch can help people with different types of emotion and attention levels to quit smoking.
Propeller Health is collaborating with the City of Louisville and other local partners to carry out a focused demonstration project that will evaluate the effectiveness of the Propeller Health approach to asthma management while exploring means to use real-time data on asthma exacerbations in a public health setting. The Asthma Data Innovation Demonstration Project (ADID) will use wireless sensor technology to develop spatial and temporal data on the use of rescue inhalers by 120 study subjects with asthma in the Louisville metropolitan area. Propeller Health will process these data to support two general strategies. Asthma self management: Rescue inhaler actuation data will be compiled into individualized feedback reports to support asthma self management. Propeller Health will combine information on individual rescue inhaler actuations with evidence-based asthma management tips into real-time reports that will be provided to subjects. ADID staff will evaluate any resulting improvements in asthma control that may be based on this information. Subjects may share reports with their healthcare providers. Municipal purposes: The second strategy is to provide aggregated and de-identified, spatial and temporal asthma rescue inhaler actuation data to City personnel and authorized public health researchers in Louisville. These data will show the times and locations of the use of rescue inhalers by the 120 study subjects throughout the greater Louisville area. ADID staff will work with City personnel and researchers to investigate how this unprecedented level of detailed information on exacerbations can be used best to increase public awareness of environmental triggers while supporting public health surveillance efforts around respiratory diseases.
The investigators will conduct low-dose intranasal allergen challenges on children/adolescents with a diagnosis of food allergy to egg/cow's milk/soya/wheat/peanut. The data will be used to determine the safety and potential utility of intranasal food challenges in the diagnosis of food allergy.
1000 women with infertility who are already decided to be treated with ICSI will be subjected to full history taking and clinical examination. On the second day of menstruation serum FSH, LH, Prolactin and Oestradiol will be assessed and the antral follicular count (AFC) will be assessed using a vaginal ultrasound scan. AFC will be defined as the number of follicles measuring 3-10mm. All patients will have standard pituitary down-regulation followed by (Human menopausal gonadotrophin (HMG) stimulation until the day of (Human chorionic gonadotrophin (HCG) administration. On the day of HCG administration, ovarian ultrasound scan will be performed using a transvaginal probe and the Preovulatory follicle count (PC) will be assessed, (PFC) is defined as number of follicles measuring≥16mm. Follicular sensitivity index (FSI) will be calculated as: (FSI =PFC*10000/AFC*Total dose of FSH)
