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.
Blood loss during liver resection surgery affects patients morbidity, short and long-term mortality. Among non-surgical interventions to minimize intraoperative blood loss and perioperative blood products transfusion, maintaining conditions of low central venous pressure is considered as standard of care. In animals undergoing laparoscopic hepatectomy, reducing airway pressures represents a minimally invasive measure to reduce central venous pressure and therefore bleeding from the hepatic vein. Neuromuscular blocking agents are usually administered during anesthesia to facilitate endotracheal intubation and to improve surgical conditions: a deep level of neuromuscular blockade has already been shown to reduce peak airway pressures and plateau airway pressures in non-abdominal procedures. Such airway pressures reduction can potentially limit bleeding from hepatic veins during transection phase in liver surgery. The aim of the present study is to evaluate the impact of deep neuromuscular blockade on bleeding (as a consequence of reduced airway peak pressure and plateau pressure) in hepatic laparoscopic resections. Patients undergoing laparoscopic liver resection will be randomized to achieve, using intravenous Rocuronium, either a deep neuromuscular blockade (post-tetanic count = 0 and/or = 1 and train of four count = 0) or moderate neuromuscular blockade (train of four count ≥ 1 and/or post-tetanic count > 5) during surgery. Neuromuscular blockade measurements will be performed every 15 minutes. The primary endpoint is to assess the total blood loss at the end of the resection phase.
Main indications for distal pancreatectomy (DP) are pancreatic body and tail tumors including ductal adenocarcinoma, neuroendocrine tumors, and cystic neoplasms. Despite a less invasive operation with lower morbidity compared to pancreatic head surgery, DP is burdened by the occurrence of clinically-relevant postoperative pancreatic fistula (CR-POPF) in a significant proportion of patients. Drain fluid amylase (DFA) on POD 1 (postoperative day 1) > 2,000 U/L appears as the best performing threshold to predict the occurrence of CR-POPF after distal pancreatectomy. Although there is preliminary evidence that early drain removal in the subgroup of patients with DFA1 < 2,000 U/L may reduce POPF, no prospective study has yet evaluated the impact of an early drain removal strategy compared to standard management. The research question of this study is to evaluate to what extent early postoperative drain removal according to a validated DFA1 impact on clinically-relevant POPF rate after distal pancreatectomy in comparison to standard drain management. The primary hypothesis is that, early drain removal will result in a reduced proportion of patients experiencing grade B-C POPF according to ISGPS definition. The proposed study is a two-group, assessor-blind, randomized trial. Participants will be randomly assigned with a 1:1 ratio into one of two groups: (1) standard drain management or (2) early drain removal strategy. In this study adults (>18 years) patients with pancreatic body or tail diseases planned for distal pancreatectomy with or without splenectomy will be enrolled.The primary outcome is the POPF at 90 days after surgery, defined as grade B or C POPF according to ISGPS definition. Participants will be asked to complete some questionnaires in order to assess their general health status, and they will be evaluated at time of hospital admission, at 15 days, at 30 days after surgery (via telephone follow-up), and at 90 days after surgery (via telephone follow-up).
Survivors of critical illness may suffer from persistent physical, cognitive and mental impairments, such as muscle weakness, dysfunction in the memory and executive domains, post-traumatic stress disorders, depression, and anxiety. This syndrome is referred to as Post Intensive Care Syndrome (PICS). This study aims to assess the frequency of impairments, their evolution over time, and to understand the pathogenetic mechanisms and the association between long-term sequelae and acute care events.
Abnormalities of the oculomotor system may represent an early sign of diabetic neuropathy and are currently poorly studied. The investigators designed an eye-tracking-based test to evaluate the oculomotor function in patients with type 1 diabetes. The investigators used the SRLab -Tobii TX300 Eye tracker®, an eye-tracking device, coupled with a software that we developed to test abnormalities of the oculomotor system. The software consists in a series of screens divided in 5 classes of parameters (Resistance, Wideness, Pursuit, Velocity and Optokinetic Nystagmus [OKN]) to evaluate both smooth and saccadic movement in different directions. 40 healthy volunteers and 40 patients with long-standing type 1 diabetes will be enrolled to analyze the alterations in the oculomotor system and function.
The aim of this study is to compare the efficacy of continuous ibrutinib monotherapy with fixed-duration venetoclax plus obinutuzumab and fixed-duration ibrutinib plus venetoclax by measuring progression-free survival (PFS) in patients with previously untreated CLL.
The purpose of this study is to determine whether oral etrasimod is a safe and effective treatment for moderately active ulcerative colitis in adult participants.
This is a randomized, double-blind, placebo-controlled, global, multicenter, Phase 3 trial evaluating the impact of trilaciclib on myelopreservation and anti-tumor efficacy when administered prior to FOLFOXIRI/bevacizumab in patients with pMMR/MSS mCRC who have not received systemic therapy for metastatic disease.
The purpose of this study is to evaluate two study medicines (encorafenib plus cetuximab) taken alone or together with standard chemotherapy for the potential treatment of colorectal cancer that: - has spread to other parts of the body (metastatic); - has a certain type of abnormal gene called "BRAF"; and - has not received prior treatment. Participants in this study will receive one of the following study treatments: - Encorafenib plus cetuximab: These participants will receive encorafenib by mouth at home every day and cetuximab once every two weeks by intravenous (IV) infusion (an injection into the vein) at the study clinic. - Encorafenib plus cetuximab with chemotherapy: These participants will receive encorafenib and cetuximab in the way described in the bullet above. Additionally, they will receive standard chemotherapy by IV infusion and oral treatment at home. - Chemotherapy alone: These participants will receive chemotherapy, the standard treatment for this condition, by IV infusion at the study clinics and oral treatment at home. This study is currently enrolling participants who will receive either encorafenib plus cetuximab with chemotherapy or chemotherapy alone. The study team will monitor how each participant responds to the study treatment for up to about 3 years.
Activation is the amount of voluntary recruitment of a muscle during voluntary contraction. Full activation implies the recruitment of all muscle fibres at their tetanic frequency. In healthy subjects, and even in sports performances, full activation may be rarely achieved despite a subjectively maximal effort. Highly decreased activation has been observed in patients affected by various orthopaedic and neurological disorders. In these subjects, paresis may be caused or aggravated by primitive impairments of the central nervous system and/or, by stimuli arising from peripheral damaged tissues that inhibit the corticospinal or the intraspinal recruitment of motoneurones ("arthrogenous muscle weakness"). There are numerous investigations in the literature on activation measured during isometric contractions, while they are substantially missing as far as isokinetic concentric contractions are concerned. There are reasons to suppose that, contrary to what has been demonstrated for healthy subjects, in patients with various motor impairments the activation is diminished the more, the higher is the joint rotation speed. The present study aims to investigate the amount of activation of the quadriceps femoris during subjectively maximal isometric contractions at 40° knee flexion (0°=complete extension) and isokinetic concentric contractions at an angular velocity of 100°/s in patients with various orthopaedic and neurologic conditions. Activation will be measured on an isokinetic dynamometer, through the "interpolated twitch technique". This consists of stimulating a representative sample of the muscle belly through an electric shock. If the shock does not generate an extra force during contraction, all muscle fibres belonging to the sample reached by the electric shock can be claimed to be recruited at their tetanic frequency. Otherwise, following the stimulus, a twitch can be observed revealing submaximal voluntary recruitment of the muscle.
Recently, a CNN-based artificial intelligence (AI) system for polyp characterization has been developed by Fujifilm Co., Tokyo, Japan. It works in conjunction with BLI system. In the present study we prospectively evaluate whether the evaluation of the endoscopist combined with the CAD system output achieve > 90% accuracy in characterization (i.e. as adenomas or non-adenomas) of diminutive rectosigmoid polyps having histopathology as reference standard. Consecutive adult outpatients undergoing elective colonoscopy, in which at least one diminutive (<5 mm) rectosigmoid polyp is detected are included. During endoscopic procedures all polyps identified by the endoscopist are documented for size, location and morphology. All diminutive polyps are characterized by a three sequential steps process: I) endoscopist prediction: the endoscopist evaluates the polyp by using BLI through the BASIC classification; the confidence level (high vs. low) in histology prediction is recorded; II) AI prediction: the AI system is switched on and the output of the automatic evaluation is recorded; this outcome is rated as stable or unstable, depending of the consistency over time of the outcome; III) combined prediction: a final classification is provided by endoscopist in light of the results of the first and of the second step; the confidence level is recorded. All polyps are resected and retrieved in separate jars and sent for pathology assessment. Only polyps characterized with high confidence will be included in the per-polyp analysis; the high-confidence characterization rate will be also calculated; the rate of polyps characterized with a CAD stable outcome will be calculated. Operative characteristics (sensitivity, specificity, positive and negative predictive value and accuracy) in distinguishing adenomatous from non-adenomatous polyps, evaluated with high confidence, will be calculated for each diminutive polyp and for each diminutive rectosigmoid polyp, having histopathology report as reference standard. The post-polypectomy surveillance intervals will be calculated on the basis of polyp histology (reference standard) in all patients according to both USMSTF and ESGE guidelines.
