NCT ID: NCT03363516 Recruiting - Clinical trials for Mild Cognitive Impairment

1-hour Post-load Hyperglycemia and Mild Cognitive Impairment

Start date: October 2016
Phase: N/A
Study type: Observational

Insulin resistance (IR), beyond its well-defined role in the appearance and progression of diabetes mellitus (DM), is the recognized pathogenetic factor underlying vascular aging. Recently, the existence of a "cerebral" IR, responsible of the appearance and progression of many forms of dementia and mild cognitive impairment (MCI), has been hypothesized. On the other hand, it is well known that DM acts as a cardiovascular (CV) risk factor per se. In the last years it has been demonstrated that also glucose normotolerant subjects who exhibit plasma glucose levels >155 mg/dL 1h-post load, have a CV risk similar to that of diabetic patients. Thus, these category of subjects is characterized by IR and, being MCI the expression of IR in the brain, the principal hypothesis of our study is that these subjects may also develop neuropsychological alterations, earlier with respect of the general population.

NCT ID: NCT03363412 Recruiting - Cirrhosis Clinical Trials

Tips Underdilatation in Patients With Cirrhosis

Start date: June 1, 2010
Phase: N/A
Study type: Interventional

The transjugular intrahepatic portosystemic shunt (TIPS) is a well-established procedure for the treatment of portal hypertensive bleeding, refractory ascites and vascular diseases of the liver. The major drawbacks of this procedure are shunt dysfunction and portosystemic encephalopathy (PSE). The availability of self-expandable polytetrafluoroethylene-covered stentgrafts (PTFE-SGs) has dramatically improved the long-term patency of TIPS. However, the incidence of PSE remains a threatening complication in about 50% of patients. The Investigators hypothesized that under-dilated PTFE-SGs would not self-expand to nominal diameter and their under-dilation would be safe and could reduce the rate of post-TIPS encephalopathy, while maintaining clinical efficacy. Aim of this proof-of-concept exploratory study is to determine whether "under-dilated TIPS" is a feasible procedure that reduces the incidence of PSE while maintaining clinical efficacy.

NCT ID: NCT03363373 Recruiting - Neuroblastoma Clinical Trials

Naxitamab for High-Risk Neuroblastoma Patients With Primary Refractory Disease or Incomplete Response to Salvage Treatment in Bone and/or Bone Marrow

Start date: April 3, 2018
Phase: Phase 2
Study type: Interventional

Children and adults diagnosed with high-risk neuroblastoma patients with primary refractory disease or incomplete response to salvage treatment in bone and/or bone marrow will be treated for up to 101 weeks with naxitamab and granulocyte-macrophage colony stimulating factor (GM-CSF). Patients will be followed for up to five years after first dose. Naxitamab, also known as hu3F8 is a humanised monoclonal antibody targeting GD2

NCT ID: NCT03361332 Recruiting - Motor Activity Clinical Trials

The Sense of Agency

SOA
Start date: April 8, 2017
Phase: N/A
Study type: Observational

The ability to recognize of being the actors of the behaviour and its consequences, the so-called "Sense of Agency" (SoA), is a crucial component of self-awareness. One key aspect is the distinction from a mere inference about the causality between an act and its consequences and the sense of being the agent of it. Despite a large number of behavioural studies, there is unsatisfactory evidence on the functional anatomical underpinnings of the SoA and the distinction between causality and the SoA proper. Here, the investigators use an implicit measurement of the SoA and its modulations during fMRI: the intentional binding phenomenon (IB). The ivestigators also study how the SoA and the ensuing neurophysiological correlates are modulated by the presence of a movement disorders, such as Gilles de la Tourette Syndrome.

NCT ID: NCT03360981 Recruiting - Clinical trials for Coronary Artery Disease

Epicardial Fat and Clinical Outcomes After Coronary Artery Bypass Grafting in Diabetics vs. Non Diabetics

Start date: September 20, 2017
Phase: Phase 4
Study type: Interventional

Cardiovascular disease (CVD) is a group of diseases including both the heart and blood vessels, thereby including coronary heart disease (CHD). To date, diabetics have a higher incidence and prevalence of multivessels CHD. Treatments in multivessels CHD in diabetics include full medical anti ischemic therapy, and revascularization therapy (Percutaneous coronary intervention (PCI) and/or Coronary artery bypass grafting (CABG)). Randomized trials comparing multivessel PCI to CABG have consistently demonstrated the superiority of CABG in reducing mortality, myocardial infarctions and need for repeat revascularizations. After the CABG treatment, diabetics vs. non-diabetics evidenced a worse prognosis, and an increased mortality. Numerous molecular, epigenetics (as microRNAs), and other metabolic risk factors may condition the worse prognosis in diabetics vs. non diabetics after CABG. In this context, an increased epicardial fat tissue thickness may be independently associated with the prevalence of diabetes, and diabetics have an higher epicardial fat tissue thickness, volumetry, and enhanced metabolism. Therefore, after CABG, lifestyle and medical improvements may lead to the reduction of epicardial fat thickness, extension, and metabolism in both non-diabetics, and diabetics, ameliorating the prognosis. At moment, epicardial tissue function in diabetics is not well investigated in literature, and no data has been reported about new hypoglycemic drugs, and its pleiotropic effects on diabetics after CABG. Indeed, our study hypothesis was that, epicardial fat tissue dimension, and metabolic activity may be related to a different expression of inflammatory, oxidative, and apoptotics molecules, and epigenetic effectors in diabetics vs. non-diabetics. Secondary, these effectors, and epicardial tissue dimension and activity, may be controlled, after CABG, by incretin treatment in diabetics. Therefore, incretin therapy may be associated to the reduction in epicardial fat tissue thickness, and extension, with down regulation of different inflammatory, oxidative and apoptotics molecules, and epigenetic effectors involved in epicardial fat metabolism. Moreover, in this study authors will evaluate in diabetics vs. non diabetics, and in diabetic incretin-users vs. never.-incretin-users, all cause mortality, cardiac mortality, and Major adverse cardiac events (MACE) after CABG in diabetics vs. non diabetics, and diabetic incretin-users (6 months of incretin therapy) vs. diabetic never-incretin-users. Authors will correlate these clinical endpoints to the study of the epicardial fat anatomy and metabolism before and after CABG, and to circulating inflammatory and pro-apoptotic markers, epigenetic effectors, and stem cells in diabetics vs. non diabetics, and diabetic incretin-users (6 months of incretin therapy) vs. diabetic never-incretin-users.

NCT ID: NCT03360591 Recruiting - Clinical trials for Coronary Artery Disease

Functional Assessment In TAVI: FAITAVI

FAITAVI
Start date: November 24, 2017
Phase: N/A
Study type: Interventional

The aim of this study is to compare the clinical outcome of patients with severe aortic valve stenosis and associated significant coronary artery disease treated with TAVI and a percutaneous myocardial revascularization dictated according to two different strategies: 1. the Angiographically-guided strategy; 2. the Physiologically-guided strategy.

NCT ID: NCT03358160 Recruiting - Orthopedic Disorder Clinical Trials

Motor Representations in Orthopedic Patients

Start date: May 31, 2016
Phase: N/A
Study type: Observational

The aim of this study is to investigate the possible effects that a motor limitation at the peripheral level might have on the ability to visually discriminate others' actions. Previous literature has shown that specific motor skills (motor expertise) facilitate the visual discrimination of domain-specific actions, and that these motor experts' superior abilities might be mediated by areas not only responsible for the visual recognition of movements (as it happens in non-expert subjects) but also involved in motor planning. Similarly, impairment in the motor system due to neurological damage modulates not only the ability to perform movements but also the ability to discriminate and predict the temporal course of observed actions. Based on these findings, it has been hypothesized that the motor representations of gait, despite being a hyper-learned motor pattern, might be subjected to modification as a result of an impairment of walking caused by a peripheral functional limitation in the lower limbs as the one characterizing orthopaedic patients who underwent a surgical operation for total knee arthroprosthesis. In this protocol, patients are thus required to perform visual discrimination tasks based on the observation of movements performed with either the upper or lower limbs, and their performance is expected to correlated with their functional impairments in movement execution. These results would indicate that the (in)ability to perform a movement might have an impact on its representation at the central level and on internal motion simulation capabilities, which also influence the ability to visual discriminate others' actions through action-perception transfer: this would suggest that rehabilitation in orthopaedic patients should take into account (and restore) such a central impairment in motor representations.

NCT ID: NCT03354247 Recruiting - Clinical trials for Non-Alcoholic Fatty Liver Disease

Lifestyle Intervention in Fatty Liver (NAFLD)

FOIEGRAS
Start date: July 1, 2017
Phase: N/A
Study type: Interventional

Non-Alcoholic Fatty Liver Disease (NAFLD), including its more pathologic consequence, non-alcoholic steatohepatitis (NASH), is believed to be the most common chronic liver disease worldwide, affecting between 6 to 37% of the population. NAFLD is a so called 'silent killer', as clinical symptoms only surface at late stages of the disease, when it is no longer treatable: untreated, NAFLD/NASH can lead to cirrhosis and hepatocellular carcinoma, culminating in liver failure. Several factors may contribute to the pathogenesis of NAFLD, including genetic assessment and mitochondrial dysfunction. Patients with NAFLD/NASH display disturbances of intestinal permeability, and gut microbiota. In the most of cases, NAFLD/NASH is strongly linked to other metabolic conditions, including visceral adiposity. Currently the best method of diagnosing and staging the disease is liver biopsy, a costly, invasive and somewhat risky procedure, not to mention unfit for routine assessment. Weight loss is the first step approach with reasonable evidence suggesting it is beneficial and safe in NAFLD/NASH patients. However, the efficacy of weight reduction for the treatment of NAFLD/NASH has not been carefully evaluated. Several studies on the effects of weight reduction on NAFLD/NASH have been uncontrolled, used poorly defined patient populations and non-standardized weight loss interventions, and lacked a well-accepted primary outcome for NASH. The objective of the project is to conduct a randomized controlled trial of 1 year-long weight reduction in the management of NAFLD/NASH patients using a lifestyle-dietary intervention program. Overweight or obese individuals with biopsy or ultrasonography (US) -proven NAFLD/NASH will be randomized to receive either standard medical care and educational sessions related to NAFLD/NASH, healthy eating, weight loss, and exercise (control group); or to an intensive weight management with a goal of at least 7-10 % weight reduction (lifestyle intervention group). The weight loss intervention will be modelled on Mediterranean-intervention-diet. The investigators hypothesize that a 7-10% weight reduction through intensive lifestyle intervention will lead to improvement of clinical, US, anthropometric, and biochemical features on patients diagnosed with NAFLD/NASH.

NCT ID: NCT03354052 Recruiting - Stroke Clinical Trials

Efficacy of rTMS on Pain Following Stroke.

Start date: December 1, 2017
Phase: N/A
Study type: Interventional

Pain is a common symptom experienced by people following stroke and can significantly interfere with participation in the activities of daily living and adversely affect health-related quality of life. Repetitive Transcranial Magnetic Stimulation (rTMS) promotes the modulation of brain activity and its prolonged and continuous application can effect plastic modification. Combining rTMS with rehabilitation treatment for primary motor cortex activation (using Gloreha® device) may have effect in reducing pain in stroke survivors. This is a pilot randomized control trial to test the effects of rTMS in stroke-related pain rehabilitation, its efficacy on pain, upper limb function, sensory function and autonomy in daily livings activities. Furthermore, we will explore the effects on pressure pain threshold, cortical excitability and EEG recording.

NCT ID: NCT03351959 Recruiting - Rectal Cancer Clinical Trials

Complete Pathologic Response Rectal Cancers

CORSiCA
Start date: January 1, 2018
Phase:
Study type: Observational

Background. About 20% of rectal cancers who underwent neoadjuvant treatment (neoCHT-RT) achieve a pathological complete response in the surgical specimen(ypT0); however, about 10% of ypT0 present metastatic nodes (N+). Although seldom analyzed, ypT0N+ identification could be crucial in order to tailor treatments. Hypotheses. The two hypotheses to test are if we can identify ypT0N+ and if N+ is an independent prognostic factor. Aim 1. To create a large Database (DB) of ypT0. Aim 2. To compare ypT0N0 vs ypT0N+ with respect of their clinical/radiological/molecular features. Aim 3. To investigate long term results. Preliminary Study. Dr Lorenzon is the PI of an Italian retrospective multicentric study conducted on 260 ypT0 focused on treatment and outcomes. Design. The PI will operate in partnership with the European Society of Surgical Oncology (ESSO). A DB will be used by ESSO-affiliated centres for collecting the clinical, pathological and radiological data of ypT0N0/N+, previously treated (last 5 years) and prospectively enrolled (6 months + 2 years of follow-up); each centre will provide a junior (<40 yrs) member for data collection and a senior investigator .for data validation; all the analyses will be centralized by the PI. ypT0N0 and ypT0N+ will be compared for the clinical/pathological variables, for the gene expression profiles of pre-neoCHT-RT biopsies (grant requested). Uni-multivariate survival analyses (end-points: OS, DFS, DSS) will be conducted at 2 years of follow-up. Impact. This is the first study aimed to investigate ypT0N+ features; their accurate identification could lead to treat safely thousands of ypT0N0/year with local excisions leaving major surgery for N+ patients. Results will change practice and reduce considerably health-related costs; moreover, the molecular profiles will open new frontiers of research.
