NCT ID: NCT03378375 Completed - Clinical trials for Amyotrophic Lateral Sclerosis

Resting Energy Expenditure Equations in Amyotrophic Lateral Sclerosis, Creation of a ALS-specific Equation

Start date: November 1996
Phase: N/A
Study type: Observational

Introduction: Resting energy expenditure (REE) formulas for healthy people (HP) are used to calculate REE (cREE) in amyotrophic lateral sclerosis (ALS) patients. In ALS an increase of measured REE (mREE) in indirect calometry (IC) compared to cREE is found in 50-60%. The aims were (i) to assess accuracy of cREE assessed using eleven formulas as compared to mREE and (ii) to create if needed a specific cREE formula for ALS patients. Method: ALS patients followed in the ALS expert center of Limoges between 1996 and 2014 and with a nutritional evaluation were included. mREE assessed with IC and cREE calculated with eleven predictive formulas (Harris Benedict (HB) 1919, HB 1984, WSchofield, De Lorenzo, Johnstone, Mifflin, WHO/FAO, Owen, Fleisch, Wang and Rosenbaum) were collected at time of diagnosis. Fat free mass (FFM) and fat mass (FM) were measured with impedancemetry. A Bland and Altman analysis was carried out. The percentage of accurate prediction ± 10%of mREE, and intraclass correlation coefficients (ICC) were calculated. Using a derivation sample, a new REE formula was created using multiple linear regression according to sex, age, FFM and FM. Accuracy of this formula was assessed in a validation sample.

NCT ID: NCT03378193 Completed - Clinical trials for Cancer of Head and Neck

Prognostic Value of 18FDG PET/CT Textural Indices in HNSCC

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

Head and neck (HN) cancer is the sixth most common malignancy worldwide, with around 800,000 new cases and 320,000 deaths in 2015. These malignancies encompass cancers of the oral cavity, oropharynx, hypopharynx and larynx and concerned squamous cell carcinomas (SCC) 90% of the time. Despite aggressive treatment strategies, the five-year survival rate has only marginally improved in the past decade especially because of a high rate (up to 40%) of loco-regional recurrence. Moreover, two-third of local relapse and lymph node metastases occur in the first 2 years after treatment. Hence, predicting tumor response to therapy remains a real challenge in head and neck cancers. Usual prognostic factors include the tumor size, the lymph node involvement, the presence of distant metastasis, the anatomic subsite, and the human papilloma virus (HPV 16, 18) infection status. However, pre-treatment selection of patients with poor prognosis or who require intensified therapy remains difficult despite their careful evaluation. HNSCC also present a high biologic heterogeneity with hypoxic area, necrotic regions, zones of high cellular proliferation and intra-tumoral angiogenic heterogeneity. A better characterization of tumor heterogeneity could help classify patients in different risk subgroups in order to improve their therapeutic management. Pre-therapeutic 18F-fluorodeoxyglucose positron-emission tomography (FDG PET/CT) is recommended by guidelines to assess remote extension of locally advanced HNSCC and/or to look for synchronous cancer. Its prognostic significance has already been suggested and a selection of patients at risk of recurrence appears possible using different quantitative parameters. Indeed, static (SUV = Standardized Uptake Value), volumetric (MTV = Metabolic Tumor Volume, TLG = Total Lesion Glycolysis) and kinetic (RI = Retention Index) parameters were demonstrated to be independent prognostic factors in several studies. Texture analysis is currently highly studied in order to characterize tumor heterogeneity, and consists in extracting texture indices from different imaging modalities such as FDG PET/CT. Calculating texture indices relies on choosing a contouring method to delineate a tumor volume of interest and selecting several parameters such as the resampling method, matrix definitions and indices formula. Several studies conducted on small series of patients with HNSCC have showed promising results to predict survival, analyzing various cancer anatomic subsites, tumor segmentation methods and texture indices. The objective of this study is to assess the prognostic value of texture indices in a large cohort of patients with HSNCC, including any anatomic subtype and staging.

NCT ID: NCT03376360 Completed - Prostate Cancer Clinical Trials

Functional Medical Imaging Quantization in Prostate Cancer

QUIP
Start date: October 1, 2015
Phase:
Study type: Observational

Prostate cancer is the most common cancer in men over 50 years old and the third leading cause of cancer death. Because of the variety of prostate cancers, different treatments exist. Several criteria guide this management in daily practice: PSA level; TNM stage (digital rectal examination, trans-rectal ultrasound and classical visual imaging) and pathological differentiation with the Gleason score, to which can be added other prognostic criteria: growth and doubling time of the serum PSA, number of positive biopsies and percentage of cancer lesions by biopsy. Functional imaging by PET and MRI is increasingly used in daily clinical practice to characterize prostate cancer, either during initial discovery or during recurrence. In this context, it is the qualitative visual analysis that is mainly used. Quantitative image analysis could add new criteria to guide patient management. Consequently, the objective of this study were: - Optimization of 18F-choline PET/CT Acquisition in Prostate Cancer - Comparison the quantitative parameters obtained by 18F-Choline PET / CT and both perfusion MRI and histological parameters.

NCT ID: NCT03374618 Completed - Clinical trials for Systemic Lupus Erythematosus

Neutrophil Extracellular Traps in Systemic Sclerosis

NET-SSC
Start date: February 23, 2018
Phase: N/A
Study type: Interventional

Systemic sclerosis (SSC) is a systemic disease characterized by limited or diffuse cutaneous sclerosis, microangiopathy, overproduction of autoantibodies and variable organ damage due to vasculopathy and/or fibrosis. The loss of self-tolerance is believed to be caused by the dysregulation of both innate and adaptive immune systems and may involve reactive oxygen species (ROS). Neutrophils are potent producers of ROS and may play a role in endothelial cells and fibrobasts dysfunction, as in autoantibodies generation. However, their role in SSC pathogenesis remains to be determined. Recent studies discovered abnormal regulation of neutrophil extracellular traps (NETs) in other auto-immune diseases such as systemic lupus erythematosus (SLE). NETs are web-like structures composed of chromatin backbones and granular molecules. They are released by activated neutrophils through a process called "NETosis". Nets were first described in 2004 as a novel host defense mechanism to trap and kill foreign pathogens. Recent evidence shows that NETs also participate in the pathogenesis of a variety of inflammatory and autoimmune diseases, including SLE. We hypothesis that this phenomenon could be dysregulated in SSC as in SLE and could play a prominent role in the induction of autoimmunity, as well as in the induction and perpetuation of organ damages.
