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 investigators propose to create a prospective Crohn Disease cohort, where patients receiving the most up-to-date therapies with a treat-to-target strategy, will be closely followed to characterize the progression of Crohn Disease by measuring the Lémann Index over time. The goal of the CROCO Study - "Crohn's Disease Cohort Study" is to promote a greater understanding of the long-term evolution of Crohn Disease , to describe prospectively the impact of different therapeutic strategies and develop accurate predictors of bowel disease damage and disability.
Non-alcoholic fatty liver disease (NAFLD) is a multifactorial disease affecting a quarter of the world population. Pathological accumulation of fat, into the hepatocytes, is the first hit and is due to altered hepatic and extrahepatic lipogenesis, lipolysis and lipophagy of the large lipid droplets. Lipophagy plays a key role in the onset of NAFLD, in the autolysosomes, small droplets of fat are catabolized by Lysosomal Acid Lipase (LAL) enzyme which hydrolyzes cholesterol esters and triglycerides forming cholesterol and free fatty acids. Our research group demonstrated that, subjects affected by NAFLD, present a reduced enzymatic activity either compared to patients with chronic liver disease of different etiology, but comparable staging, either compared to healthy control subjects. Leukocytes are the main site of enzymatic activity in the blood, however, our research group has shown that it can also be detected inside the platelets, demonstrating how the LAL activity can be exchanged between cells. Furthermore, our group has shown, for the first time, how the intracellular enzymatic activity is reduced, independently of the platelets and leukocytes count and progressively from chronic liver disease up to cirrhosis. Among factors which contribute to altered lipid metabolism, the genetic predisposition to the accumulation of hepatic fat must be counted. Several variants of genes that code for proteins implicated in the digestion or storage of fats, are involved. In this study were considered: patatin-like phospholipase domain-containing 3 (PNPLA3), Transmembrane 6 superfamily 2 (TM6SF2) and 17β-Hydroxysteroid dehydrogenase type 13 (HSD17B13). The rs738409 variant (C> G, p.I148M) of the PNPLA3 gene consists of a protein in which the catalytic site is not entirely accessible to the substrate which, consequently, accumulates in the storage site. This variant is commonly found in NAFLD subjects and it has been widely reported how the variant carriers progress faster towards severe disease (steatohepatitis) than wild type subjects. The TM6SF2 gene encodes a membrane transporter involved in the triglycerides movement, the rs58542926 (C> T E167K) variant has been associated with an increased predisposition towards liver fibrosis in NAFLD subjects. This is likely due to the loss of protein function resulting in hepatic retention of triglycerides and cholesterol. Unlike PNPLA3 and TM6SF2, the rs72613567 (TA> TAA) variant of the HSD17B13 gene has a protective effect against NAFLD progression. It is characterized by a protein loss of function that protects against chronic liver damage and mitigates the progression of the disease although how the protective effect occurs is still under study. Due to the multifactorial etiology of the disease, to the need of carrying out a targeted surveillance in predisposed genetic subjects and, in order to prevent NALFD progression towards severe pathological forms characterized by an increased mortality, in this study, 316 subjects will be enrolled. They will be divided as follows: Italian Caucasians, aged> 18 and <70 years, with non-cirrhotic NAFLD and carriers of the PNPLA3 I148M variant, and, 158 Italian Caucasian subjects, aged> 18 and <70 years, with non-cirrhotic NAFLD and carriers of the wild type allele. The following exclusion criteria will be considered: any type of malignant disease in the past 5 years, any type of inflammatory or autoimmune disease, corticosteroids for systemic use, any type of drug that may affect body weight or body composition, insufficiency kidney (GFR <90 mL / min), heart failure (NYHA classes II-IV), any type of liver disease rather than NAFLD, excessive alcohol intake (> 140 g / week for men and 70 g / week for women), participation in a weight reduction program in the past 3 months, bile salts, cholestyramine in the last 6 months prior to enrollment, previous cholecystectomy, gallbladder disease. Peripheral blood will be withdrawn in order to measure haematic lipids (total cholesterol and fractions, triglycerides), total blood LAL activity, to perform genetic analysis and finally to evaluate lipase activity into the platelets. Hepatic elastography will be also executed, in 100 patients, according to the presence/absence of the PNPLA3 variant, in order to weigh up the genetic predisposition on NAFLD development or progression Finally, in subjects who present a lipase activity 30% lower than the normal value (0.88 ± 0.38 (mean ± SD), the methylation of the LIPA promoter will be studied.
The study objective is to determine the biomarker status of a participant's tumor tissue and use that status to determine eligibility for a linked Roche clinical trial.
The objective of this study is to verify which is the most effective type of rehabilitation treatment (rehabilitation based on core strengthening vs pilates) in patients suffering from low back pain. The secondary objective is to verify whether the use of Kinesio Tape (KT) associated with rehabilitation treatment can have greater effects in the motor and functional recovery of patients suffering from Low Back Pain than traditional rehabilitation.
Retrospective/ prospective, multicentre, international observational study on long-responders with non-small cell lung carcinoma patients treated with anti Programmed cell Death 1/ Programmed cell Death Ligand 1 (anti-PD1/PD-L1) in any line of treatment for at least 24 months with response partial/complete response or disease stability. Patients will be divided into two cohorts based on whether they stopped treatment at 24 months (not for toxicity) or continued by clinical choice and stratified according to treatment line and baseline PD-L1 expression.
Periodontal treatment relies on a sequential series of different phases that are usually incapsulated in three main phases: non-surgical treatment, surgical phase and, finally, supportive phase. Whilst, on the one hand not all patients may undergo surgical interventions, on the other hand non-surgical periodontal and supportive treatment are administered to all subjects affected by periodontitis. Both phases are constituted by closed, non-surgical, root instrumentation which is often carried out with similar techniques. Thus, non-surgical periodontal treatment (NSPT) is the one key stone of the treatment of periodontitis. NSPT is very efficacious. A significant majority of the diseased sites are usually managed non-surgically (Graziani et al., 2017)). Moreover, bleeding on probing and symptoms are significantly decreased by NSPT. Importantly, NSPT is also capable to reduce systemic inflammation (Teeuw et al., 2014), improve glycaemic control (Sanz et al., 2018) and overall ameliorate oral health related quality of life (Graziani, Music, et al., 2019). Lastly, NSPT is cost effective as its costs are moderate and it may be performed by both dentists and hygienists. Nevertheless, NSPT is often uncapable to solve an entire clinical case and surgical treatment is advocated as in fact the complete closure of the pockets ranges from 57 to 75% according to a follow-up of 3⁄4 months or 6/8 respectively (Solini et al., 2019). Periodontal surgery is also effective, but it is nonetheless a surgical intervention which cannot be defined as deprived of side effects (Graziani et al., 2018). Thus, in order to improve the outcome of NSPT numerous adjunctive treatment modalities have been advocated (Braun et al., 2008; Graziani et al., 2017; Haffajee et al., 2003). Yet the objective of reducing the need for surgery has been rarely evaluated. Recently, our group ran a trial in which enamel matrix derivatives (EMD) has been applied as non-surgical adjunct. The findings highlighted that EMD application lowers systemic inflammation, increases blood clot stability and, locally, reduces of the need for surgery by 32% compared to the control group without EMD. Thus, a multicentre responding to the following questions: - Flapless application of EMD reduce the need for periodontal surgery? - Are the results stable over time? - Can the results be generalized among different clinicians? EMD is a resorbable, implantable material and supports periodontal regeneration, which takes place over more than a year. It consists of hydrophobic enamel matrix proteins extracted from developing embryonal enamel of porcine origin in a propylene glycol alginate carrier. The gel has a suitable viscosity to facilitate application directly onto root surfaces exposed during periodontal surgery. Once applied onto an exposed root surface the protein self assembles into an insoluble three-dimensional matrix and creates a suitable environment for selective periodontal cell migration and attachment, which re-establishes lost tooth supporting tissues. Subsequent to formation of new attachment, alveolar bone can also be regenerated due to the osteogenic capacity of the restored periodontal ligament. EMD is degraded by enzymatic processes of normal wound healing.

The prevalence of critical ab extrinsic compression of left main coronary artery (LMCA) is very high in patients with pulmonary arterial hypertension (PAH) symptomatic for angina (up to 40% according to a recent study of 121 patients with PAH). The element that most of all correlates with the degree of coronary stenosis is the diameter of the pulmonary artery (PA). In particular, a diameter ≥ 40 mm has a sensitivity of 83% and a specificity of 70% in patients with angina. Critical stenosis of LMCA is a risk factor for sudden death and in these condition percutaneous coronary angioplasty with stent implantation has proven to be a safe and effective long-term procedure. Preliminary data from a retrospective analysis of the registry of patients with PAH in Bologna (ARCA registry, 109/2016/U/Oss) highlights that even in PAH patients asymptomatic for angina, compression of LMCA can occur in up to 13% of patients and the main predictive parameter of compression was found to be a diameter ≥ 42 mm (with a sensitivity of 87% and a specificity of 77%). Performing a screening test by coronary-CT scan in all subjects suffering of PAH with a PA diameter ≥ 40 mm even if asymptomatic for angina could therefore help to identify patients with PAH at increased risk for sudden death at an early stage.
