Filter by:Mesenteric traction syndrome (MTS) is defined as hypotension, tachycardia and facial flushing in the first hour of surgery, caused by mesenteric traction/abdominal exploration. MTS occurs frequently during abdominal surgery, with incidence around 80 % during open surgery, and lower during minimally invasive surgery. MTS can be divided into different severities using the degree of facial flushing, with the most severe level of MTS being associated with increased postoperative morbidity. Today MTS is diagnosed and graded subjectively by the surgical team, with marked difficulty and limitations. Therefore the investigators developed a cut-off value using the Laser Speckle Contrast Imaging (LSCI), which the investigators wish to confirm in a new cohort, while also examining whether LSCI is interchangeable with digital thermography, which is simpler and cheaper to perfom. The investigators will measure facial perfusion during the first hour of surgery and take blood samples at predefined timepoints to use for biochemical verification of the different severities of MTS. Three cohorts we planned to include 45 open esophagectomies or gastrectomies 50 whipple surgery 20 robot assisted esophagectomies or gastrectomies These patients will be use in multiple articles examining different aspects of MTS One study examining LSCI and thermography for the identification and grading of MTS will use 60 patients undergoing open esophagectomy or gastrectomy or whipple surgery, in this study patients will not be excluded if they are found to be disseminated. However we ended up including 37 open esophagectomies - due to few patients undergoing open esophagectomy, this were included over a time period of almost 2,5 years 50 whipple 11 Robotic esophagectomies - due to LSCI being impossible to use on robotic esophagectomies and thermography being diffciult to fit on these patients and as such not being feasible
The investigator will apply 16 sessions of repetitive transcranial magnetic stimulation (rTMS) over 4 consecutive days for adult patients suffering from Tourette's Syndrome. Following rTMS, patients will undergo 8 sessions of Comprehensive Behavioral Intervention for Tics (CBIT) over 10 weeks via telemedicine. Clinical improvement in tic severity will be the primary outcome measure. Secondary outcome measures including underlying physiological effects will be measured via functional magnetic resonance imaginge (fMRI), high-density electroencephalograhy (HD-EEG), and TMS.
Although proprioceptive neuromuscular facilitation (PNF) techniques have been used in the treatment of different shoulder problems, PNF techniques in scapular and upper trunk patterns with extremity pattern have not been considered as a possible option for the treatment of Subacromial Impingement Syndrome (SIS). The aim of this study was to evaluate the effects of different PNF patterns in SIS.
The TILE pilot study will be a multicenter, open-label, assessor-blinded RCT (randomized control trial) comparing extended LMWH (Low Molecular Weight Heparin) vs. DOAC (Direct Oral Anticoagulants) to PTS (prevent post thrombotic syndrome) in patients with DVT (Deep Vein Thrombosis).
This research study is determining if a drug called Pimavanserin if safe and effective in the treatment of the symptoms of Tourette Syndrome. Pimavanserin is an investigational drug for Tourette Syndrome, which means it has not been approved by the United States Food and Drug Administration (FDA) to treat Tourette Syndrome. Pimavanserin has been approved by the FDA as a treatment for hallucinations in Parkinson's Disease. It is currently marketed under the name NUPLAZID (pimavanserin) capsules by Acadia Pharmaceuticals.
The SARS-CoV2 pandemic and resulting COVID-19 infection has led to a large increase in the number of patients with acute respiratory distress syndrome (ARDS). ARDS is a severe, life-threatening medical condition characterised by inflammation and fluid in the lungs. There is no proven therapy to reduce fluid leak, also known as pulmonary oedema, in ARDS. However, recent studies have discovered that imatinib strengthens the cell barrier and prevents fluid leak in the lungs in inflammatory conditions, while leaving the immune response intact. The investigators hypothesize that imatinib limits pulmonary oedema observed in ARDS due to COVID-19, and may thus help to reverse hypoxemic respiratory failure and to hasten recovery. The hypothesis will be tested by conducting a randomised, double-blind, parallel-group, placebo-controlled multi-centre clinical study of intravenous imatinib in 90 mechanically-ventilated, adult subjects with COVID-19-related ARDS. Study participants will receive the study drug (imatinib or placebo) twice daily for a period of 7 days. The effect of the intervention will be tested by measuring extravascular lung water (i.e. pulmonary oedema) difference between day 1 and day 4, using a PiCCO catheter (= pulse contour cardiac monitoring device). Other measurements will include regular blood tests to investigate the safety and the pharmacokinetic properties of imatinib, as well as biomarkers of inflammation and cellular dysfunction. Furthermore, parameters of ventilation and morbidity and mortality will be recorded as secondary outcome measures.
N-acetylcysteine (NAC) allows the elimination of reactive oxygen species (ROSs) and it has an anti-inflammatory effect. For this reason, NAC has been used and researched for treatment of several diseases, such as autoimmune diseases. In these diseases there are a process of oxidative stress due to chronic inflammation, which promotes an imbalance between ROSs levels and the cellular capacity to eliminate reactive intermediates and repair the resulting damage through antioxidants. The imbalance between the production of free radicals from oxygen and antioxidant species may also be involved in the pathogenesis of primary Sjögren's syndrome (pSS). In fact, increased levels of oxidative stress markers were detected in biopsy samples from minor salivary glands in these patients. Treatment of pSS is not well established and it is also not able to modify the evolution of the disease, being often only symptomatic. In addition, there is little data in the literature regarding the true efficacy of NAC in the treatment of pSS and the few existing studies have evaluated heterogeneous populations (including patients with other causes of sicca syndrome) and validated instruments to measure the symptom index and disease activity were not use in these previous studies. Thus, the present randomized double-blind clinical study aims to evaluate the efficacy of NAC in the control of sicca syndrome symptoms in a homogeneous population of patients with pSS (not only regarding the classification criteria, but also regarding the low rate of systemic disease activity at study inclusion) through tests widely accepted in the literature. Additionally, the investigators will study the possible role of NAC on oxidative stress in peripheral blood and saliva of these patients.
Characterization of patients with long COVID syndrome including symptoms, medical history and persistent organ damage.
This study aimed to investigate the relationship between CCTA-based pericoronary inflammation and plaque features as well as local immune-inflammatory biomarkers in ACS patients. It is hypothesized that perivascular FAI might serve as a reliable sensor of coronary immune-inflammatory disorder, and closely related to the plaque vulnerability.
Colorectal cancer (CRC) is the second cause of cancer-related death in western countries. CRC prevention and screening are major public health issues. Better knowledge of colorectal carcinogenesis could lead to better prevention. Gut microbiota (GM) is a complex community of bacteria, fungi, protozoa, viruses and bacteriophages which live in a symbiotic and epigenetic relationship with the host. GM can promote either digestive health or CRC through inflammatory and proliferative effects. Lynch syndrome (LS) is the most common familial CRC syndrome with a lifetime CRC risk of 52% in women and 69% in men. The risk of CRC depends upon type of altered mismatch-repair gene and environmental factors (diet, exercise, obesity, tobacco and alcohol intake, etc.). Regular surveillance including annual or biannual colonoscopy is recommended in LS patients. Chemoprevention has the potential to represent a cost-effective intervention in these high-risk patients and could allow a delay in colonoscopy surveillance. Regular low dose aspirin use is associated with a 20 to 30% reduction in the risk of sporadic colonic adenomas and CRC. The real benefit of aspirin is still to be consolidated. AAS-Lynch trial is an ongoing prospective multicenter (n=37), double-blind, placebo-controlled, randomized clinical trial, designed to investigate whether daily aspirin, at a dose of 100 or 300 mg compared with placebo, would decrease the occurrence or recurrence of colorectal adenomas in LS patients. The primary endpoint is the number of patients with at least one adenoma detected by chromo-endoscopy 48 months after initial colon clearance. At randomization and at the end of study, stool collection, blood collection, quality of life questionnaire, validated food frequency questionnaire (SU-VI-MAX2) and physical activity questionnaire are performed. The ongoing AAS-Lynch study allow accessing to a unique fecal collection in very well characterized LS patients including a comprehensive dietary evaluation at high risk for colorectal neoplasia and planned colonoscopy surveillance during a 48 months follow-up, exposed or not exposed to chronic low dose aspirin. The expertise of the scientific consortium with state of the art microbiota analysis, the comprehensive collection of data and the prospective design of the study will allow the evaluation of the true role of gut microbiota in CRC carcinogenesis.
