Colorectal cancer screening showed an increased incidence of malignant colorectal polyps pT1 after endoscopic excision. Their management is not yet standardized, for the presence of histological features increasing early lymph node involvement. The literature has proposed several histopathological criteria, for which the risk of lymph node metastasis can vary (6-20%), but final data are not yet available. Aim 1.To collect data about patients undergoing an endoscopic polypectomy with histologic finding of pT1, retrospectively and prospectively, dividing both databases into two groups, endoscopic group (EG) and surgical group (SG) Aim 2. To analyze retrospectively which pathological criteria can increase the risk of lymph node metastasis and to elaborate a prognostic score for lymph node metastatic risk Aim 3. To verify prospectively the prognostic score capacity on predicting lymph node metastasis Aim 4. To calculate the disease free survival, overall survival, local recurrence rate and distal recurrence rate and verify if there is a difference between EG and SG According to literature, the most important histopathological criteria to establish the high risk of lymph node metastasis are: 1. Lateral margin of healthy tissue (high risk: <1mm and piecemeal polypectomy) 2. Depth of submucosa invasion (high risk: >1000 μM or sm2-sm3 for sessile polyps; Haggitt level 4 for pedunculated polyps) 3. Vascular invasion (high risk: presence) 4. Lymphatic invasion (high risk: presence) 5. Tumor budding (high risk: presence) 6. Tumor differentiation (high risk: grade G3-G4 or mucinous) A database will be used by all participating centres for collecting clinical and pathological data. All the analyses will be centralized by the PI. Uni-multivariate analyses will be conducted at the end of data collection for retrospective arm and at 2 years of follow-up for prospective arm. Impact: This study aimed to investigate pathological risk factors for lymph node metastasis in pT1 colorectal polyps after endoscopic polypectomy; their accurate identification could lead to improve their management, avoiding useless complementary surgery. Results could change clinical practice and reduce health-related costs.
The purpose of this extension trial is to evaluate the long-term safety of tralokinumab.
Background: Achalasia is a primary rare esophageal motor disorder of the esophagus (annual incidence of 1:100,000 persons). Recently, a new endoscopic technique, Per-Oral Endoscopic Myotomy (POEM), has been introduced with excellent success rates. Several studies have evaluated complications of POEM but there is a lack of knowledge on the potential risk of bacteremia or microbial translocation during the endoscopic intervention and, also, there aren't evidences regarding the use of antibiotics before/after POEM. Microbial translocation (MT) is the passage of both viable and nonviable microbes across the anatomically intact GI barrier to the mesenteric lymph nodes, and possibly other tissues. Gram-negative bacteria contain lipopolysaccharides (LPSs) coating their thin peptidoglycan cell wall. The presence of LPS, an endotoxin, in the plasma has been correlated to sepsis and septic shock through the activation of the inflammatory host defence via binding to soluble CD14 (sCD14) which initiates downstream cytokines (like IL-6, IL-8 and tumor necrosis factor (TNF-α)) and, also, through the production of sCD14 and LPS-binding protein (LBP) by the innate immune system. Objectives: Considering POEM a clean-contaminated procedure, it should be assessed whether the post-POEM fever or systemic inflammation is a cytokinin-mediated or an infection-related fever. Thus, aim of the study is to evaluate the presence of inflammation mediators, bacteremia and microbial translocation post POEM, to guide future antibiotic prophylaxis/therapy in patients undergoing this procedure. Methods: All patients who will undergo POEM at _Investigator's Department from June 2017 to June 2019 will be enrolled in a prospective, interventional randomized clinical trial (RCT). Patients will be randomized in two groups. The Group A, prophylaxis group, will receive antibiotics (Cefazolin 2 gr i.v.) only before procedure whereas Group B, short therapy group, will receive antibiotics before POEM (Cefazolin 2 gr i.v.), continued for the first 24 hours and then per os (Amoxicilline/Clavulanic Acid 3 gr/die) for 3 days. For each patient we will be evaluated: dosage of IL-6, IL-1β, TNF-α, sCD4, LPB, LPS and blood cultures. Expected results: we expect that the prophylaxis group vs short therapy group, has a prevalence of fever and/or systemic inflammation not higher than 10% difference of the fever related to the procedure.
The study aims at evaluating the introduction of tomosynthesis in mammography screening, analyzing the benefits, disadvantages and feasibility in current clinical practice. It involves women aged 45-46 that will be divided, by drawing lots, into two groups: one group will do the 2D digital mammography (control group), while the other group (intervention group) will do tomosynthesis. In the intervention group the 2D two-dimensional mammography will be reconstructed starting from tomosynthesis without exposing women to other radiation.
To establish baseline prospective efficacy data of current FIX prophylaxis replacement therapy in the usual care setting of hemophilia B subjects, who are negative for nAb to AAV-Spark100, prior to the Phase 3 gene therapy study. To establish baseline prospective efficacy data of current FVIII prophylaxis replacement therapy in the usual care setting of hemophilia A subjects, who are negative for nAb to AAV6, prior to the Phase 3 gene therapy study. The enrollment for hemophilia A participants is completed. At this time participants are only being enrolled for hemophilia B cohort.
The principal objective is to test non-inferiority of the CRT-DX system as compared to a conventional CRT-D system, in terms of the combined endpoint of mortality, hospitalizations due cardiovascular causes, any complication leading to loss of lead functionality, in the subset of patients without evidence of sinus dysfunction on optimal therapy.
Cow's milk (CM) allergy is the most frequent food allergy in the first years of life, with prevalence rates estimated in the range of 2-3%. The elimination of CM is the mainstay of treatment, but accidental exposure to CM proteins is not uncommon, with a considerable risk of severe allergic reactions. Recent evidence suggests that early oral exposure in young children may protect to the development of allergy. On the same way, strategies have been developed for the use of oral exposure as immunotherapy for the treatment of children with established food allergy even if available data on the use of oral immunotherapy in infants with food allergy are very limited. The aim of this study is to evaluate the feasibility of an oral immunotherapy protocol, started in the first year of life, in children with CM allergy.
Oncologic laryngeal surgery is a challenge for anesthesiologists and awake fiberoptic intubation (AFOI) is mandatory to manage difficult airways and prevent the Can't Intubate Can't Oxigenate (CICO). Laryngospasm and oversedation are dangerous complication often life-threatening in this kind of patient. Superior laryngeal nerve block (SLNB) could be an alternative technique useful to reduce risks and to improve patient comfort. Aim of this study is to assess the procedural comfort of the SLNB during AFOI, in a population of patients suffering from severe airways obstruction undergoing pharyngeal-laryngeal surgery. 40 patients will be randomized in two groups(20 for each group) and will be treated with continuous infusion of remifentanil, topic anesthesia of the base of the tongue and intercricoid block. In group A will be associated the SLNB; placebo will be administered in group B.
HHT or Rendu-Osler-Weber disease is a genetic disease with an autosomal dominant inheritance pattern, characterized by widespread telangiectases that can involve several organs including the intestinal tract and the liver. Liver involvement by HHT is characterized by widespread diffuse liver vascular malformations that give origin to arteriovenous, arterioportal and portovenous shunts. The prevalence of hepatic involvement in HHT can reach 78%. Less commonly, patients may also develop porto-systemic encephalopathy (PSE). However, there are no studies on the possibility that patients with HHT might develop mHE, a highly plausible hypothesis considering the presence of diffuse macroscopic and microscopic porto-systemic shunt in this pathological condition.
The study will analyze differentially regulated genes involved in oxidative stress and toxicology in peripheral blood mononuclear cells (PBMCs) of patients who underwent arthroplasty under three different anesthetic methods. The investigator hypothesized that anesthesia procedures trigger toxicity, thus inducing changes in the messenger ribonucleic acid (mRNA) profile. The results may provide a more profound understanding of the molecular mechanism of anesthesia and in overcoming the adverse effects arising from their use.
