NCT01820793
Escherichia coli is the primary cause of urinary tract infections and Gram-negative bacteremia worldwide. Since the early years of the 21st century, E.coli has acquired a new mechanism of resistance to antibiotics: extended spectrum β-lactamase (ESBL), type CTX-M. These ESBL inactivate most β-lactams, the preferred class of antibiotics for the treatment of severe E.coli infections. Moreover, the strains that produce these ESBL are often resistant to other classes of antibiotics. Their rapid spread constitutes a major public health concern because of a serious risk of therapeutic impasse. Treatment options in cases of infection with ESBL-producing E.coli are often limited to carbapenems, a class of more recently developed β-lactams. Carbapenems have a very wide spectrum of activity but their effectiveness is threatened by the emergence of strains producing carbapenemases. The development of therapeutic alternatives to treat ESBL-producing E.coli infections is therefore essential. Cephamycins, including cefoxitin, are β-lactams marketed in the seventies but their use was practically abandoned when wide spectrum antibiotics became available. They are distinguished by the presence of an α-methoxy group in position 7 which interferes with the action of the extended-spectrum β-lactamase and renders it ineffective against cephamycins. Cefoxitin is therefore active in vitro against ESBL-producing E.coli and offers the advantage of a narrower antibacterial spectrum, thus reducing the selection pressure and the emergence of resistance. However, the in vivo activity of cefoxitin for the treatment of ESBL-producing E.coli infections has never been measured. Furthermore, available pharmacokinetic and pharmacodynamic (PK/PD) data for cefoxitin are dated and incomplete, which raises many questions concerning the optimal dosage regimen. We have shown in a mouse model of ESBL-producing E. coli CTX-M pyelonephritis that cefoxitin efficacy is comparable to that of carbapenems without selecting resistant mutants. Cefoxitin could thus constitute an alternative to carbapenems for the treatment of pyelonephritis caused by ESBL-producing E.coli.
NCT03396380
The aim of this work is to evaluate the effect of vitamin D supplementation in overweight infertile women with PCOs undergoing induction of ovulation.
NCT03395535
This is a randomized study with two treatment arms: 'initial Selective Laser Trabeculoplasty (SLT) followed by conventional medical therapy as required' ('Laser-1st') and 'medical therapy without laser ('Medicine-1st'). It compares quality of life in the two arms at three years, while also examining the incremental cost and cost-effectiveness of Laser-1st versus Medicine-1st.
NCT03226665
Small bowel obstruction (SBO) is a common presentation to the emergency department (ED) and represents 15% of hospital admissions for acute abdominal complaints. Plain radiography, although traditionally recommended as the initial diagnostic imaging modality of choice, has a sensitivity of only 59% to 77%. When clinical and radiographic assessment is indeterminate, computed tomography (CT) becomes the test of choice due to its superior resolution and increased ability to identify both obstruction and its aetiology Aim: this is a prospective study in a sample of patients presenting to the emergency department (ED) with abdominal pain, vomiting, or other symptoms suggestive of a SBO (history of previous surgeries, constipation, abnormal bowel sounds, and abdominal distention). Patients will be evaluated with US prior to x-ray and CT, with possible diagnostic confirms by endoscopy or surgery.
NCT03394586
TNF inhibitors have improved treatment options for patients with inflammatory bowel disease (IBD) and three TNF inhibitors, infliximab, adalimumab and golimumab are available for treatment of ulcerative colitis in Switzerland. However, these drugs have been tested under ideal conditions in randomized controlled trials. Real-world data are needed to complement this information. It is the aim of our study to test, whether patients with ulcerative colitis can be effectively treated with golimumab in a real world setting in Switzerland. The investigators will use data from the Swiss IBD cohort study (SIBDC) in Switzerland. They will identify all SIBDC patients with UC treated with Golimumab and perform a retrospective chart review. The investigators will acquire patient reported outcomes and objective measures for inflammation at baseline, at 6-10 weeks and at 6 and 12 months after golimumab treatment. Primary endpoint will be clinical response (i.e. meaningful improvement) at 6-10 weeks. Secondary endpoints will be clinical response at 6 and 12 months and clinical remission (i.e. free of symptoms of disease).
NCT02505594
Obstructive sleep apnea (OSA) is a common disorder with major cardiovascular sequelae. A recent study confirmed that OSA is associated with impaired exercise capacity and increasing OSA severity predicts worsening exercise capacity, which is a marker of potential increased cardiovascular risk. However, potential mechanisms of decreased exercise capacity caused by OSA remain unclear. Several pathophysiologic mechanisms of OSA have been proposed and investigators hypothesize that endothelial dysfunction leading to exercise-induced right ventricular dysfunction and associated pulmonary hypertension is the potential mechanism for impaired exercise capacity in OSA.
NCT02306473
This is a clinical trial designed to test the hypothesis that measuring the absorption and excretion of inhaled mannitol will provide a clinically useful marker of airway epithelial permeability in asthma.
NCT01061671
To determine the effect of daily administration of 40 mgms simvastatin taken for at least 12 months (range 12-36 months) on the frequency of exacerbations of chronic obstructive lung disease (COPD) in patients with moderate to severe COPD who are prone to exacerbations and do not have other indications for statin treatment.
NCT03387306
Purpose: To analyze the relationship between normal-tension glaucoma (NTG) and serum bilirubin levels. Materials and Methods: This research included 38 patients with NTG and 38 healthy controls with similar age and sex distribution, for a total of 76 subjects. Serum samples were taken from all of the subjects, direct serum bilirubin, indirect serum bilirubin and the total serum bilirubin were measured.
NCT00867529
This phase II trial studies giving rituximab before and after a donor peripheral blood stem cell transplant in patients with B-cell lymphoma that does not respond to treatment (refractory) or has come back after a period of improvement (relapsed). Monoclonal antibodies, such as rituximab, can interfere with the ability of cancer cells to grow and spread. Giving rituximab before and after a donor peripheral blood stem cell transplant may help stop cancer from coming back and may help keep the patient's immune system from rejecting the donor's stem cells.
NCT02510924
Airtraq sp has been proven effective for intubating patients presenting with difficult airway. The Airtraq sp allows visualisation of the tracheal inlet only for the intubator. By adding a smartphone with a dedicated app (Airtraq Mobile) to the Airtraq sp, the visualisation of the tracheal inlet is possible for all the airway providers. The investigators aim to demonstrate that the addition of the Airtraq Mobile app improves success rate of intubation (primary endpoint), as well as confort of the airway provider, shortens time for intubation and reduces injury to the patients.
NCT03387345
The purpose of this research was to investigate 5 different formulations of whole grain barley and refined white rice against a control of white bread on post-prandial glycemic response, as well as self-reported hunger/satiety in a randomized cross-over trial.
NCT03386201
