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.
Pulmonary embolism (PE) should be suspected in patients with dyspnea, chest pain, syncope, shock/hypotension, or cardiac arrest. Discriminating patients in different categories of pre-test probability of PE has become a key step in all diagnostic algorithms for PE. The most frequently used clinical prediction rule is the Wells score ("PE likely" > 4 points and "PE unlikely" ≤ 4 points). PE can be safely ruled out in patients with a "PE unlikely" associated with a negative d-dimer test result. Conversely, patients with "PE likely" or positive d-dimer level should undergo further diagnostic testing, like multidetector computed tomography pulmonary angiography (MCTPA). Wells score accuracy is not optimal. Vein and lung US can be rapidly performed at bedside as an extension of physical examination and have a high specificity. The aim of this study is to evaluate if the combination of clinical data reported in the Wells score and US data obtained from vein and lung US (US Wells score) has a better diagnostic accuracy compared to traditional Wells score. In adult patients suspected of PE traditional Wells score will be calculated and vein and lung US (multiorgan US) will be performed in all patients and and US Wells score calculated. The US Wells score differs from the traditional Wells score in the following items: "signs and symptoms of DVT", replaced by "vein US showing DVT", and "alternative diagnosis less likely than PE" replaced by "alternative diagnosis less likely than PE after multiorgan US". This latter item is considered positive if at least one subpleural infarct is detected at lung US, and negative if no subpleural infarcts are detected and an alternative diagnosis like pneumonia, pleural effusion or diffuse interstitial syndrome may explain the symptoms of presentation. If no findings are detected at lung US, the points for the item remain the same assigned by traditional Wells score. Final diagnosis of PE will be preferentially established by MCTPA and in patients discharged without a second level imaging test because of negative Wells or d-dimer, and patients with not conclusive second level diagnostic test, will enter the 3 months follow-up protocol. The diagnostic performance of traditional and US Wells scores will be assessed by calculating sensitivity, specificity, positive, and negative predictive value, and likelihood ratios. Failure rate and efficacy of d-dimer in patients stratified as "PE likely" and "PE unlikely" will also be calculated.
BACKGROUND Unpredicted difficult tracheal intubation (DTI) with Macintosh laryngoscopy occurs frequently in obese patients. We investigated the incidence of DTI using the GlideScope® videolaryngoscope (GVL) with an algorithm based on a pre-operative assessment with the El Ganzouri Risk Index (EGRI). METHODS We prospectively enrolled morbidly obese patients (BMI>40 kg/m2) undergoing abdominal surgery. Patients were scheduled for flexible fibre optic bronchoscopic intubation (FFBI) or GVL intubation if the EGRI score was ≥7 or <7, respectively. The primary outcome was the occurrence of DTI that was defined as Cormack and Lehane (C&L) grades ≥III, Intubation Difficulty Scale (IDS)>5 and modified IDS (mIDS)>5. A numeric rating scale (NRS) was also used. Secondary outcomes included intubation success during the first attempt, the time to Cormack (TTC), the time to intubation (TTI), failure to intubate, oxygen desaturation and difficult ventilation.
Clinical study suggests that beta-blockers by decreasing heart rate together with an increase in stroke volume do not negatively affect cardiac output allowing an economization of cardiac work and oxygen consumption in patients with septic shock. Whether this hemodynamic profile leads to an amelioration of myocardial performance is still unclear. The objective of the present study is therefore to elucidate whether a reduction in heart rate with esmolol is associated to an improvement of cardiac efficiency in patients with septic shock who remained tachycardic after hemodynamic optimization.
This open-label, international, multicenter study will investigate the safety and efficacy of venetoclax (GDC-0199) in combination with bendamustine plus rituximab (venetoclax + BR) compared with BR alone in participants with relapsed and refractory fNHL, comparing two chemotherapy-containing regimens (Chemotherapy-Containing Cohort). In addition, an exploratory analysis of the safety and efficacy of venetoclax in combination with rituximab (venetoclax + rituximab), a chemotherapy-free regimen, will be performed (Chemotherapy-Free Cohort). Assignment to the Chemotherapy-Containing or Chemotherapy-Free Cohort will be decided at the discretion of the Investigator, unless one of the cohorts is not open to enrollment; in which case, participants may be enrolled only to the open cohort. The first 6 participants enrolled in the Chemotherapy-Containing Cohort (or more if required) will comprise the Safety Run-In group for Treatment Arm B, dosing venetoclax at 600 milligrams (mg) in combination with BR. Once a dose has been chosen from the Safety Run-In Period, randomization to the two treatment arms of the Chemotherapy-Containing Cohort (Arms B and C) will begin.
The current study will compare PK, efficacy, safety, and immunogenicity of PF-05280014 (Trastuzumab-Pfizer) in combination with Taxotere® and Carboplatin (Paraplatin) versus Herceptin® (Trastuzumab-EU) approved in the EU in combination with Taxotere® and Carboplatin (Paraplatin) in patients with operable HER2 positive, breast cancer in the neoadjuvant setting. The hypothesis to be tested in this study is the percentage of patients with steady state Cycle 5 Ctrough (Cycle 6 pre-dose) >20 µg/mL of trastuzumab-Pfizer is similar to EU-approved trastuzumab, using a margin of -12.5%.
The purpose of this study is to compare the safety, efficacy and calcium metabolism of up to 8 weeks of treatment with calcitriol 3 mcg/g ointment versus its vehicle, when used twice daily, without occlusion, to treat children aged 2 to 12 years, with plaque psoriasis.

This protocol is a phase I/II multicenter study designed to assess the safety and the efficacy of the proposed combinations in relapsed and/or refractory Multiple Myeloma (MM) patients.
The present study aims at studying how safe and tolerable a new therapy for patients with Acute Lymphoblastic Leukemia (ALL) is. This new therapy consists of an immunotherapy, that is an approach focusing on the immune system, and it targets ALL patients in complete remission but who may still have the disease at a cellular level (this is called 'minimal residual disease'). For any further information, please, discuss with your treating physician.
Treatment of acute ischemic stroke (AIS) is aimed at salvaging viable but ischemic brain by opening the occluded artery and restoring anterograde perfusion as quickly as possible. Time saved while making critical decisions correctly is vital in AIS management. Conventional angiography is invasive, resource intensive and not feasible as a fast diagnostic tool. Perfusion CT and MRI are both susceptible to patient motion, need trained personnel to process and take at least 10-30 min to acquire and interpret. The investigators have developed a new imaging tool, multi-phase CT Angiography (CTA), which generates multiple time resolved images of backfilling arteries beyond a blocked artery filled by collaterals. Investigators seek to determine: i) if patients with AIS will have a differential clinical response to early recanalization based on collateral status assessed on multi-phase CTA, ii) if the extent to which collateral assessment on multi-phase CTA resembles perfusion CT in predicting which patients will have good clinical outcome with early recanalization, iii) Identify determinants of variability in native collateral status in patients with acute ischemic stroke. Investigators hypothesize that patients with good and intermediate collaterals on multi-phase CTA achieve good clinical outcome with early recanalization (within 4 hours of baseline imaging); patients with poor collaterals do not do well even with early recanalization. Prove-IT is a prospective multi-center hospital-based cohort study of 500 consecutive patients with acute ischemic stroke presenting within 12 hours of stroke symptom onset with evidence of intracranial occlusion on routine CTA over 3 years. Calgary and seven other comprehensive stroke centers will recruit patients into this study. Primary outcome is defined as a National Institute of Health Stroke Scale (NIHSS) score of 0 to 2 at 24 hours or an 8-point drop in NIHSS score from baseline to 24 hours. Secondary outcomes are a) 90-day modified Rankin Score (mRS) 0-2 or equal to the pre-stroke mRS; b) percent neurologic improvement comparing NIHSS at baseline to 24 hours; c) 90-day NIHSS score 0-2; d) infarct volume on 24 hour imaging and e) parenchymal intracerebral hemorrhage type 1 and 2 (ECASS II criteria) at 24 hrs. Prove-IT looks to establish the ideal imaging selection tool for intra-arterial (IA) and thrombolysis decisions in the setting of AIS which is widely available, and can quickly and reliably detect salvageable brain.
