NCT ID: NCT04774133 Recruiting - Prostatic Neoplasm Clinical Trials

The Immunodynamic Effect of Radiotherapy in Prostate Cancer Patients.

Start date: February 14, 2019
Phase: N/A
Study type: Interventional

Radiotherapy has an important role in the treatment of prostate cancer both as curative treatment and postoperative or salvage ones. Several studies demonstrated a significant reduction of lymphocytes during RT but there are only a few studies monitoring these cells in the treatment of prostate cancer. This study will enroll 50 patients with hystologically proven prostate cancer who will undergo to radiotherapy according to Institutional protocols. This study aims to evaluate the effect of RT on immuno-regulatory B, NK, T, B and T lymphocyte subpopulations (Breg and Treg) and plasma cells, quantitative / qualitative changes,their correlations with the clinical course of the disease and acute and late toxicity. In parallel, using multicolor panels (12 colors) we will evaluate the expression of inhibitory checkpoints and TGFβ signaling. The final objective is to identify new therapeutic targets to be combined with RT.

NCT ID: NCT04771949 Recruiting - Periodontitis Clinical Trials

Prevalence and Environmental Risk Indicators for Periodontitis. A Cross-sectional Study

Start date: February 20, 2021
Phase:
Study type: Observational

Periodontitis is a biofilm-mediated chronic inflammatory disease with a multi-factorial etiology; it belongs to the group of diseases classified as "Non-communicable Diseases" (NCDs). According to the results of the Global Burden of Disease Study of 2017, it is the sixth most prevalent disease worldwide and it constitutes a heavy burden on health costs. Risk factors for such disease include non-modifiable risk factors, i.e. familiarity, diabetes, cardiovascular diseases, metabolic syndrome, as well as modifiable risk factors, i.e. diet, stress and low physical exercise. Given the significant impact of oral health on the quality of life and overall well being of the individual, many studies investigated the importance of risk factors for oral health. In particular, there is some evidence that more severe manifestations of periodontitis are associated with lower physical activity (De Oliveira Ferreira et al., 2019), poor sleep quality (Karaaslan & Dikilitaş, 2019) and more perceived stress (Coelho et al., 2020). With regards to diet, despite the high number of studies demonstrating an anti-inflammatory effect of the Mediterranean Diet, no study has ever investigated the adherence to Mediterranean Dieta to the oral health status. From a methodological standpoint, investigations regarding environmental factors are mainly carried out through questionnaires administration, whose validity and reproducibility had been previously demonstrated. The novelty introduced by the present study would be a complete analysis of the effects of lifestyles (diet, sleep quality, physical exercise, perceived stress) on the periodontal status of the individual.

NCT ID: NCT04771468 Recruiting - Ischemic Stroke Clinical Trials

"Hemodynamic Changes During Endovascular Revascularization for Acute Stroke. An Observational Study".

Start date: October 1, 2021
Phase:
Study type: Observational

Neurocardiology is an emerging specialty that addresses the interaction between the brain and the heart, i.e. the effects of cardiac injury on the brain, and the effects of brain injury on the heart. Accumulating clinical and experimental evidence suggests a causal relationship between brain damage and heart dysfunction.

NCT ID: NCT04770974 Recruiting - Bladder Cancer Clinical Trials

Urothelial Cancer Tumor Bio-markers and Physical-spectroscopic Characteristic

Start date: December 10, 2020
Phase:
Study type: Observational

Our multicenter observational study is a non-profit prospective study. The study was born from the Amplitude Project, which comprise the SOD of Minimally Invasive Robotic Urological Surgery and Renal Transplants of AOU Careggi with the University of Florence, as well as with the National Research Council (CNR) and the University of Milan Bicocca (UNIMIB) The study consists of a phase of enrollment of patients who will be admitted to the SOD of Mini Invasive Robotic Urological Surgery and Renal Transplantation of AOU Careggi. Enrollment in the study does not alter normal clinical practice and does not involve additional risks for patients. Patients will have to meet the inclusion and exclusion criteria of the study and will be enrolled sequentially, until the established sample size is reached. Patients undergoing surgery for the removal of bladder neoplasm, be it endoscopic or surgical with radical intent (cystectomy), will be taken a fragment of tumor bladder tissue, on which histopathological analysis will be performed. In patients undergoing radical cystectomy only, a fragment of healthy urothelial tissue, free from neoplasia, will also be removed. The samples will be performed in patients under general and / or spinal anesthesia in case of TURB, thus not causing pain or discomfort to the patient, or ex-vivo on the operative piece in case of radical cystectomy, without causing further damage or pain to the patient. From these samples, specially stored in solutions that keep their characteristics unaltered, a 3D culture model (organoid) will be obtained both from cells obtained from bladder cancer and from healthy tissue on which biomolecular, metabolomic and spectroscopic characterization studies will be tested and carried out. with a view to staging and grading bladder neoplasia.

NCT ID: NCT04770376 Recruiting - Ovarian Cancer Clinical Trials

Evaluation of the Predictive Value of Blood Levels of Angiopoietin 1 and Endothelial Internal Tunica Cell Kinase 2 in Patients With Ovarian Cancer Treated With Chemotherapy Associated to Bevacizumab

Start date: October 12, 2020
Phase:
Study type: Observational

This is a monocentric prospective observational pilot study of translational research in women with advanced ovarian epithelial cancer. The main purpose of this study is to evaluate the predictive value of response to treatment with bevacizumab of the circulating levels of Ang1, Tie2 and VEGF before start of therapy. Secondary aims of the study are to explore the predictive value of response / resistance to bevacizumab of changes in circulating levels of Ang1 and Tie2 during treatment and at progression of disease, and to explore the possible role of circulating VEGF in the modulation of bioavailability of bevacizumab.

NCT ID: NCT04769947 Recruiting - Clinical trials for Chronic Myeloid Leukemia

Italian Treatment Free Remission Registry

Start date: August 9, 2021
Phase:
Study type: Observational [Patient Registry]

The investigator propose an extension of the previous National, multicentric study, promoting an observational registry, both retrospective and prospective, in order to expand and further characterize the series of Italian patients with Philadelphia-positive, chronic phase CML (CP-CML) who discontinue TKIs in an off-protocol setting. As safety concerns may arise for patients receiving long-term treatments, and due to the growing number of patients discontinuing TKIs in clinical practice, the study aim to collect all available data regarding feasibility and freedom from progression of the cohort of patients.

NCT ID: NCT04769895 Recruiting - Clinical trials for Steroid Refractory GVHD

MaaT013 as Salvage Therapy in Ruxolitinib Refractory GI-aGVHD Patients

ARES
Start date: March 25, 2022
Phase: Phase 3
Study type: Interventional

MaaT013 showed interesting results in steroids and ruxolitinib-resistant aGVHD patients with gut involvement (55% ORR at D28) and 47% and 39% OS at 6 and 12 months respectively (Malard 2020), therefore warrant being tested as salvage therapy in steroid and JAK inhibitors-resistant GI-aGvHD patients. Given the absence of an approved 3rd line strategy or 2nd line strategy in ruxolitinib intolerant patients and the extremely poor prognosis of these patients, who are mostly left with no viable therapeutic option, a single-arm open-label design was proposed.

NCT ID: NCT04769622 Recruiting - Periodontitis Clinical Trials

Influence of Environmental Factors on the Efficacy of Non-surgical Periodontal Treatment. A Pre-post Quasi-experimental Study

Start date: February 16, 2021
Phase:
Study type: Observational

Periodontitis is a biofilm-mediated chronic inflammatory disease which causes the destruction of the supporting tissues of the tooth. Risk factors for periodontitis include familiarity for periodontal diseases, diabetes, cardiovascular diseases, metabolic syndrome, obesity and stress. Some studies demonstrated how these risk factors negatively influence the patients' response to non-surgical periodontal treatment. The success of non-surgical periodontal therapy is defined through the treat-to-target concept (i.e. a maximum of 4 sites with Probing Pocket Depth >5mm and presence of Bleeding on Probing); therefore, periodontal treatment is successful whenever this threshold is reached. Moreover, given the available data regarding the association between more severe forms of periodontitis and a lower frequency of physical activity, a worse sleep quality and more perceived stress, it is reasonable to hypothesize that these factors could influence the patients' response to non-surgical periodontal treatment. With regards to diet, despite many studies appraised the anti-inflammatory effect of the mediterranean diet, no study has ever related adherence to Mediterranean Diet to oral health status. The novelty that the present study would introduce is the evaluation of how environmental factors (i.e. diet, physical exercise, perceived stress) influence patients' response to non-surgical periodontal therapy.
