Filter by:Participating in genetic cancer risk assessments (GCRA) for hereditary breast and ovarian cancer can inform treatment and risk management decisions and improve breast cancer outcomes. However, Latina and Black women underuse GCRA services, which may increase breast cancer disparities. This study will adapt and test the impact of an easily scalable novel Tutoring System intervention to enhance GCRA use and improve psychosocial outcomes in a clinical sample of underserved Latina and Black women at risk of hereditary breast and ovarian cancer.
Several methods are available to measure ankle brachial index (ABI) non-invasively. A recent scientific statement of the AHA considers the Doppler method as the reference. However because Doppler devices are not widely available in primary care, several attempts have been made to propose alternative methods, among whom oscillometric methods (automatic blood pressure machines) have attracted most attention. We hypothesize that: - the diagnostic characteristics (i.e. sensitivity, specificity and AUC) of the oscillometric method would be very good as compared to the Doppler method. the oscillometric method would have better intra- and inter-observer reproducibilities as compared to the Doppler method.
The existence of an adipose tissue microbiota causally involved in the triggering of a low grade inflammation could resemble what observed in liver fibrosis. To generate microbial hypotheses putatively responsible for the onset of liver fibrosis we sequenced the 16SrDNA gene from liver biopsies from 36 obese patients (ROLIVER cohort) and describe an original mathematical approach to decipher signatures of early stage of liver fibrosis F0, F1, F2.
Non specific chronic low back pain (LBP) is a debilitating disorder characterized by tremendous personal and socioeconomic impact, with long-term sick leave, low quality of life, and very high financial costs. Evidence suggests that patients with non specific LBP presented with altered muscle activity pattern when compare with healthy people. It has been reviewed that exercise therapy was effective for modulation of muscle dysfunction in chronic low back pain. However, there is a lack of objective assessment of the pain relief in low back pain rehabilitation. Clinical application of surface electromyography (EMG) may provide a quantitative and objective tool to evaluate the rehabilitation outcome in patients with non specific chronic low back pain before and after treatment. Objectives: To verify the usefulness of surface electromyography (EMG) in low back pain (LBP) rehabilitation assessment. Setting: Out-patient physiotherapy musculoskeletal rehabilitation
A prospective cohort study that will be conducted at Sultan Qaboos University Hospital. It aims to determine the outcomes, in terms of, activity level, functional level, subjective knee function, range of motion, stability, and failure, among patients with acute ACL injuries, who undergo arthroscopic primary ACL repair; and to compare these results with patients who undergo arthroscopic ACL reconstruction. To the investigators' knowledge, there is a dearth of studies looking into the outcomes of arthroscopic primary ACL repair and this going to be the first study in the Middle East. The investigators believe that arthroscopic primary ACL repair is superior to arthroscopic ACL reconstruction; and conducting this research project will elucidate the previously abandoned facts about acute ACL repair; and will eventually have a huge impact in the field of orthopedic surgery.
The overall objective of this study is to use patient-centered in vitro and in vivo models to answer the fundamental question of whether or not pathogenic mutations in BRCA1/2 result in an increased risk of CV disease
Hemophagocytic lymphohistiocytosis in adults (HLH) is at 68% mortality whereas 78% of all cases remain undiagnosed though therapies are available which clearly reduce mortality. The investigators aim to systematically investigate this life-threatening hyperinflammatory syndrome in intensive care units (ICU) in order to detect biomarkers that are highly sensitive and highly specific for HLH in ICU compared to patients with sepsis.
The study evaluates the effects of the drug Metformin on the oxygen content in cancer tissue. Low oxygen concentration in cancer tissue accelerates cancer growth. Moreover, the response to radiation therapy is worse when tissue oxygen is low, because radiation therapy depends on oxygen to unfold therapeutic effects. Metformin has been used to treat type II diabetes for over 50 years and features additional properties that could slow down cancer growth. One of these properties is the improved oxygen concentration in cancer tissue. This effect has been proven for various cancers. This study was planned to verify this effect in head and neck cancer. Patients who suffer from cancer of the mouth and are planned for surgical removal of the cancer will be given Metformin for 9 to 14 days. The tissue removed in the subsequent surgery will be compared to a tissue sample that had been taken from the same patient prior to Metformin intake. To evaluate the oxygen content in the tissue samples, the expression of genes that react to oxygen levels will be measured and compared between the samples taken before and after treatment with Metformin. A secondary aim is to evaluate whether changes in the oxygen content within the tumor can be visualized by means of magnetic resonance imaging (MRI). Therefore, participants undergo an MRI scan, before and after Treatment with Metformin. The changes in the MRI will be correlated to the changes measured in gene expression.
Electrosurgery is fundamental to the precise, fast and bloodless preparation of internal thoracic artery grafts in cardiac surgery. The PEAK PlasmaBlade is a monopolar electrosurgical device that uses pulsed radiofrequency energy to generate a plasma-mediated discharge along an insulated electrode, creating a cutting edge while the blade stays near body temperature. The aim of this study is to compare the histological samples, cardiac computed-tomography of graft patency, and clinical outcomes of patients after off-pump coronary artery bypass grafting with preparation of the internal thoracic arteries by a conventional electrosurgical device and the PlasmaBlade.
