There are about 21062 clinical studies being (or have been) conducted in Italy. The country of the clinical trial is determined by the location of where the clinical research is being studied. Most studies are often held in multiple locations & countries.
The purpose of this study is 1) to investigate whether the use of BIS as a guide to the administration of inhaled anesthetic (sevoflurane or desflurane) compared with the use of hemodynamic parameters (blood pressure and heart rate) would affect the occurrence of implicit memory and /or dreams recall and 2) to check whether the occurrence of implicit memory and/or dreams recall is related with MAC (Minimal Alveolar Concentration) of inhalational anesthetics and/or preoperative anxiety levels.
1. To investigate whether the auditory stimulation causes changes in hormones levels (cortisol+prolactin) during general anesthesia. 2. To determine if there is a correlation between hormones levels (cortisol+prolactin) and dreams recall. 3. To investigate whether, in patients receiving auditory stimulation, there is a correlation between hormones levels (cortisol+prolactin), serum remifentanil concentration and detection of implicit memory. 4. To investigate the presence of primary auditory cortex activation (temporal lobe) in patients with implicit memory and in those with dreams recall using the EEG-ERP 128 channels GES300 EGI system.
TegaCHG is a multicentric randomized study aimed at evaluating the possibility that the use of TegaDerm CHG dressing may reduce the incidence of catheter related blood stream infections (CRBSI). It implies the comparison between the incidence of CRBSI in patients with central venous catheter dressed with TegaDerm without chlorhexidine gluconate (CHG) and with CHG. The primary endpoint is the occurrence of CRBSI and the secondary endpoints are: catheter colonization (growth of microbes from the culture of catheter tip, > 15 CFU according to semi-quantitative method or > 1000 CFU according to quantitative method); incidence of catheter exit site infection; occurrence of catheter related infections/sepsis or other severe infection-related complications; safety profile evaluation: occurrence of hypersensitivity to the dressing on the basis of local objectivity (erythema, edema, other) or on that of patient symptoms (itch, burning sensation); relating to the device performance: incidence of high/medium/low dressing edge lift, ability to visualize the catheter insertion site, easiness of removal, easiness of dressing application; incidence of unscheduled dressing change. The study hypothesis implies that the use of slow release device containing chlorhexidine may decrease the incidence of CRBSI. This has already been showed for chlorhexidine impregnated sponges. Scope of the study is to verify if this property is also true for TegaDerm CHG,which is a new chlorhexidine-releasing dressing in which the medication is directly released by an integrated transparent gel pad, so that the catheter exit site remains visible and easy to inspect without removing the dressing.
Recruitment of at least 10 adult patients (men and women) among individuals affected and admitted to the hospitals identified for the clinical study. All patients shall be between 18 and 75 years of age, with confirmed diagnosis of cryptococcosis or aspergillosis . During therapy (14 days) and examination (28 days), the patients will be subject to 7 doctor's visits (day 1,3,7,10,14,21, and 28).
The ESOS (Endoscopic Saphenous harvesting with an Open CO2 System) trial is a prospective randomized trial for coronary artery bypass grafting (CABG) surgery to compare endoscopic open CO2 harvesting system versus conventional vein harvesting.
Helicobacter pylori colonises an estimated 50% of the world´s population (Taylor & Blaser, 1991; Go, 2002). Despite clear clinical guidelines on the treatment of this infection (Malfertheiner et al. 2007) there is a drive to find alternative ways to control this infection in a wider perspective without the complications of induction of antibiotic resistance in the pathogen. L. reuteri has been widely studied in clinical trials and has been shown to have probiotic, health-promoting effects in both adults and children (Connolly 2004; Casas & Dobrogosz, 2000). L. reuteri has been shown in numerous studies to be safe for human consumption and it has been shown to colonise the human gastrointestinal tract (Wolf et al., 1995, Valeur et al., 2004). Studies using supplementation with L. reuteri in both symptomatic and non-symptomatic H. pylori-infected subjects show a clear reduction of infection load after 4 weeks of use and this was concomitant with a reduction in symptoms associated with the infection (Imase et al. 2007; Francavilla et al. 2007, unpublished data). Further, dietary supplementation with L. reuteri during and after the period of H. pylori eradication therapy has also been shown to reduce the side effects of this therapy without affecting the degree of eradication (Lionetti et al., 2007). It is also feasible, through the inhibitory action of L. reuteri on H. pylori, that pre-exposure to L. reuteri may weaken H. pylori and make it more susceptible to antibiotic attack during eradication. However, an earlier pilot study was not been able to demonstrate a reduction in gastric inflammation caused by H. pylori. This pilot study was performed with L. reuteri ATCC 55730 that has since been found to lack anti-inflammatory activity in in vitro screens. Recent selection of natural, human L. reuteri strains has identified a specific strain with strong anti-inflammatory properties in vitro (Lin et al, 2007 and submitted 2007). A combination of this strain, together with the earlier proven L. reuteri strain, is expected to lead to both a reduction of H. pylori load as well as a reduction in the gastric inflammation related to the pathogen.
This is a prospective, observational, multicenter study. The primary aim of the study is to assess the accuracy of spiral CT scan to detect right ventricular dysfunction as compared to current 'gold standard'in patients with pulmonary embolism. At the purpose of this study right ventricular dysfunction as assessed by transthoracic echocardiography and serum levels of troponin are considered as gold standard. The secondary aim of the study is to assess the prognostic value of right ventricular dysfunction as assessed by spiral CT scan.
RATIONALE: It is not yet known whether a J-pouch colorectal anastomosis is more effective than a straight colorectal anastomosis in treating patients with rectal cancer who have undergone surgery to remove the tumor. PURPOSE: This randomized clinical trial is studying J-pouch colorectal anastomosis to see how well it works compared with straight colorectal anastomosis in treating patients with rectal cancer who have undergone surgery to remove the tumor.
Primary Hypothesis: Prophylactic Vitamin C Intravenous Infusion at the time of percutaneous coronary intervention (PCI) would limit the size of the infarct, assessed by measurements of cardiac biomarkers, during acute myocardial infarction. Secondary Hypotheses: Prophylactic Vitamin C Intravenous Infusion at the time of percutaneous coronary intervention (PCI) would limit the size of the infarct, as measured by the area of delayed hyperenhancement that was seen on cardiac magnetic resonance imaging (MRI), assessed on day 5 after infarction, during acute myocardial infarction.
The notable development and diffusion of prosthetic surgery of the abdominal wall over the last few years has led to the introduction of light weight meshes. The efficacy of inguinal hernia repair with light weight prosthesis, as well as the better or worse biotolerability with respect to those of light weight, remains questionable in literature, where a clear answer still remains to be given. If there exists a connection between the quantity of material implanted, the immunological reaction to the mesh, the induced oxidative stress and the degree of cicatrization, and consequently the long-term result of the efficacy of the operation, remains to be demonstrated. There are few studies on the immunological reaction to polypropylene meshes, and none on the oxidative stress induced by the mesh. Moreover, only one study has been published that clearly correlates the immunological reaction to the amount of prosthetic material, but was carried out on only a few patients. The aim of this research is to show if there is a relationship between the amount of prosthetic material used and immunological reactions as well as postoperative oxidative stress, and thus to evaluate, if present, the differences in the biological reaction and biotolerability between light-weight and heavy-weight meshes on a statistically significant number of patients.
