Digital Breast Tomosynthesis (DBT) is a technology that has been developed to improve lesion detection in dense breasted women. Even though DBT has been regarded as a study for dense breasted women, it may also improve lesion detection at an earlier stage and smaller size in women with less dense breast tissue. The overlapping of tissue on a standard of care 2D mammogram leads to decreased cancer detection, it also contributes to pseudo lesions that mimic cancers. This leads to patients being asked to come back for additional imaging including mammogram and/or ultrasound images. DBT has shown to decrease call back rates by up to 43% in reader studies. Even though these results are promising they were not done in a realistic clinical setting.The purpose of this study is to evaluate the FDA-approved combination standard digital mammography (DM) and DBT technology and its impact on our clinical practice.
The purpose of this study is to evaluate the effect of atorvastatin on the pharmacokinetic profile of irinotecan and SN-38. To further evaluate the safety of atorvastatin in combination with FOLFIRI. To further evaluate the safety and of irinotecan in combination with atorvastatin.
To evaluate the efficacy of continuous renal replacement therapy (CRRT) during orthotopic liver transplantation (OLT) in clearing excess solutes and improving acid-base parameters. The investigators hypothesize that the use of intra-operative CRRT in OLT recipients is associated with increased solute removal and improved acid-base statues when compared to controls who do not receive CRRT
Ocular surface disease (OSD) is a significant health problem that affects more than 10 million persons in the United States alone. OSD is highly prevalent among medically treated patients with glaucoma and is associated with the number of intraocular pressure (IOP)-lowering medications used. The purpose of this study is to determine the potential effectiveness of anoritega-3 fatty acid nutritional supplement in the treatment of ocular surface disease associated"with the use of glaucoma eye drops
The overall objective of this proposal is to develop a non-invasive, inexpensive and accurate device that detects VOCs in exhaled breath for lung cancer screening. Toward this goal, the team will design and fabricate a biophotonic platform consists of arrays of silicon micro-ring resonator sensors coated with polymers with different organic functionalities, in which each sensor is widely responsive to a variety of VOCs for the detection of lung cancer by means of breath testing. The team will identify signature VOCs as lung cancer biomarkers by comparison VOC contents between alveolar gas that directly sampled from the nodule or mass and exhaled breath using gas chromatography/ mass spectrometry. The specific aims of this proposal are as followings: Aim 1: To develop a biophotonic platform for the detection of VOCs Aim 2: To achieve multiplex detection of VOCs with high sensitivity and specificity using a novel biophotonic device. Aim 3: To evaluate the device as a lung cancer screening tool by testing both healthy and lung cancer breath samples
Anaphylaxis is defined as a serious allergic reaction mediated by IgE that is often difficult to diagnose due to the wide heterogeneity of clinical manifestations. The inciting agent is often difficult to pinpoint and may include food, environmental allergens in patients undergoing allergen immunotherapy, insect stings, and medications. Evidence of allergy by demonstration of a positive skin test to the inciting agent, is helpful only if skin testing is available. The only diagnostic modality that is useful in the diagnosis of anaphylaxis when IgE skin testing is not available and the inciting agent is unknown, is an elevated serum tryptase level. However, a diagnosis of anaphylaxis can be made without a tryptase level or if the tryptase level is normal. A simple, non-invasive test for patients with anaphylaxis is not currently available and would be helpful to diagnose and to guide further management options. Patients who develop anaphylaxis to environmental allergens or venoms during routine outpatient subcutaneous allergen or venom immunotherapy are an ideal population to study as we are able to evaluate these specific reactions in a controlled, clinical environment. Although anaphylaxis is uncommon, the incidence has been estimated to vary between 0.01 and 4 percent of all allergy injections. Subcutaneous allergen or venom immunotherapies are a well established form of therapy for patients with allergic rhinitis, allergic asthma, or a confirmed sensitivity to stinging insects. Serial blood sampling can be performed in this group of patients during a reaction and at baseline one week after a reaction, thereby allowing each patient to serve as his or her own biological control. Metabolomics is the study of metabolic pathways and the unique biochemical molecules which result from the regulatory response to physiological stressors, disease processes, drug therapy, or allergen or venom immunotherapy. By measuring changes in metabolite concentrations, the range of biochemical effects and therapeutic intervention can be determined. The investigator plans to use metabolic profiling of blood samples collected at the time of anaphylaxis and one week after, to see if a simple, non-invasive test for patients with anaphylaxis could be developed.
The purpose of this study is to see if MR-guided laser ablation can effectively treat prostate tumor recurrences.
The purpose of this research study is to investigate whether breast density measured by a safe, painless imaging method (called Diffuse Optical Spectroscopic Imaging - DOSI) can detect the decrease of breast density in subjects who receive tamoxifen when compared to patients who do not receive any drug. If decreased density can be reliably detected, it may help determine which subjects will benefit by taking tamoxifen or other chemoprevention drugs.
Step 1: Identification and characterisation of the TREM1L protein from samples already available characterised at the hospital Central of Nancy Step 2: Study of the isoforms of TREM1L in correlation with the prognosis of sepsis, Step 3: implementation of assay methods for TREM1L (ELISA or SUPRA MS) Step 4: Validation of assays for TREM1L and its isoforms in a larger number of subjects (inclusion of samples from Dijon CHU and Besançon CHU)
This pilot clinical trial studies isolated limb perfusion with melphalan in treating patients with stage IIIB-IV melanoma or sarcoma. Drugs used in chemotherapy, such as melphalan, work in different ways to stop the growth of tumor cells, either by killing the cells or by stopping them from dividing. Heating a chemotherapy solution and infusing it directly into the arteries around the tumor may kill more tumor cells.
