Filter by:Adult patients (>18 years) with newly diagnosis of Ph negative myeloproliferative neoplasms (MPNs) according to WHO 2016 criteria, will be recruited to this study. This study is the result of the collaboration the Hematology Division of Federico II University Medical School of Naples (Italy), that performed the US investigation and the IRCCS SYNLAB SDN where the patients carried out MR. The study is conducted in accordance with the Declaration of Helsinki. All subjects gave informed consent to receive both US and MR scans of the spleen. All spleen US scans were performed by the same operator (with>10 years of experience in abdominal US), who used an EPIQ 5 Philips instrument with a 1-5 MHz broadband curvilinear probe. The spleen was scanned in patients who were fasting, in the longitudinal and transverse planes by using an intercostal approach, a subcostal approach, or both. The patient was placed in a supine or right-sided position until complete organ visualization was achieved. Perimeter, longitudinal diameter (LD), and area, defined as the maximum measurements with splenic borders and angles clearly defined, were measured, and SV (in milliliters) was calculated automatically. For each subject, the mean value of 3 measurements repeated on the same imaging session was calculated and recorded for final analysis. Within two weeks from the US, each patient underwent an MRI of the upper abdomen to evaluate the splenic volume. MRI examinations were performed using a 3T Biograph mMR scanner (Siemens Healthcare, Erlangen, Germany) with 4-channel flex phased-array body coil. Routine clinical abdominal MRI acquisition includes coronal T2W Half-Fourier Acquisition Single-shot Turbo spin Echo imaging (HASTE), axial T1 Dual-echo FSE, axial T2 TSE Fat Sat, and an axial diffusion-weighted imaging (DWI). The DWI includes an apparent diffusion coefficient (ADC) map that was automatically generated at the time of acquisition. At last, an isotropic 2mm3 axial Volumetric Interpolated Breath-hold Examination (VIBE) sequence for SV evaluation was acquired. For the latter, attention was paid to optimize the field of view to the spleen, in order to reduce patient's apnea and possible respiratory artifacts. A radiologist with mote than 10 years of experience in abdominal MRI reporting performed measurement of the three orthogonal diameters of the spleen for each patient. Subsequently, SV was calculated using ITK-SNAP software and semi-automatic 3D segmentation approach, firstly based on a signal threshold.
The main purpose of this study is to develop a computer-aided prediction model for NAC treatment response. Based on the heterogeneity of internal parametric tumor composition commonly observed, this study will utilize the histologic characteristics and treatment response to investigate the image features as input data for predicting treatment response using Deep Learning technology. Using this technique, preoperative treatment evaluation may be facilitated by tumor heterogeneity analysis from developed dynamic radiomics, and the possibility of personal medicine can be realized not far ahead. In the first two years of this study using images from DCE-MRI, PET/CT and QDS-IR, we plan to develop the image processing algorithms, including segmenting breast and tumor region, extracting image feature which reflects angiogenic properties and permeability of tumor, which are highly correlated with NAC treatment response. During the third year of the project, the morphology and texture features from first two years can be combined for PET/MRI and prediction model can be achieved in accordance with the features extracted from dynamic features extraction using longitudinal images of PET/MRI.
The goal of this study was to identify the prevalence of mechanical ventilation-associated complications and co-morbidities in pediatric patients admitted to the PICU of Benha University Hospital, uncover how often these problems occur, their types, factors linked to them and to compare the epidemiology of MV-associated complications.
Aim of the study was to evaluate the color stability of lithium disilicate ceramic veneers and zirconia reinforced lithium silicate ceramic veneers by using two different types of resin cements including light cured and dual cured cements.
To verify the efficacy and tolerability of Activated Piroctone Olamine (Blue Cap Foam, label volume 100 ml) by CATALYSIS, S. L. Madrid, applied in the management of all types of dermatitis (atopic, seborrheic, eczema) in patients with significant manifestations of the disease in varying areas of the body of varying extent and to assess differences in individual tolerability and the final effect in a group of selected patients aged 3 to 18 years.
To assess the safety and of a single dose of IV infusion of placenta derived Mesenchymal Stem Cells (PLMSCs) in patients with secondary progressive Multiple Sclerosis (SPMS) disease. Monitoring will be encompassed baseline assessments and follow-ups over subsequent months, evaluating clinical signs, Expanded Disability Status Scale (EDSS), cytokines, diffusion tensor imaging (DTI), functional MRI (fMRI), cognitive & psychological evaluations, and flow cytometry for B cell markers.
Introduction: The aim of this study comparing the post operative pain after the retreatment of asymptomatic and symptomatic teeth that during single visit treatment with rotary and reciprocal nickel titanium files. Methods: One hundred and forty one patients scheduled for non-surgical endodontic retreatment were included for evaluation. Eighty five patients who needed endodontic retreatment were assingned to 2 groups according to semptomatic or asemptomatic teeth and 4 subgroups with rotary and resiprocal files. Endodontic filling material was removed with One Flare and MicroMega REMOVER files in the retreatment kit. Patients then recorded their postoperative pain on a VAS scale at 24h, 48h, 72h, 7 days and 14 days post-treatment. Results were analyzed using the Shapiro-Wilk, Mann-Whitney U, Kruskal-Wallis, Dunn-Bonferroni and Pearson Chi-square tests.
The goal of this clinical trial is to compare the airway management effects of flexible reinforced laryngeal mask and endotracheal tube in childhood adenotonsillectomy. Participants will be randomly allocated to two groups: endotracheal tube group (ETT) and flexible reinforced laryngeal mask group (FLMA). For those in ETT group: they will be intubated after induction of anesthesia .For those in FLMA group: they will be put in flexible reinforced laryngeal mask after induction of anesthesia . The investigators will compare FLMA with ETT to see if flexible reinforced laryngeal mask can be used safely and effectively in childhood adenotonsillectomy，and if there will be less severe adverse events in FLMA.
To compare the efficacy of topical tapping vs vibration in lowering pain scores for periocular anesthesia injections.
The goal of this study is to compare the impact of metabolic surgery and a class of anti-diabetes medications (Glucagon-like peptide-1 receptor agonists,GLP-1 RAs) on occurrence of diseases involving small and large vessels such as heart disease, kidney disease, and disease of the retina (a part of the eye), as well as deaths.
