Population Patients with a diagnosis of Rheumatoid Arthritis (RA), moderate or high clinical disease activity (CDAI>10) despite conventional synthetic (cs)DMARD(s) therapy for ≥3 months, naïve to biological (b) and targeted synthetic (ts)DMARDs therapy and a maximum of 2 swollen joints (out of 44 joints) Study design Randomised multicentre, parallel-arm clinical study Primary objective Non-inferiority of the experimental arm (i.e. clinical therapy together with ultrasound guided treatment decision) in comparison to the control arm (clinically guided decision) concerning the proportion of patients reaching low disease activity (CDAI ≤10) and a minimal clinical important improvement (MCII: improvement of ≥6 points if starting from moderate disease activity, any case starting from high disease activity and achieving low disease activity) or remission according to ACR/EULAR index-based remission criteria (CDAI ≤2.8/Boolean remission) at week 24. Intervention This is a randomised multicentre, national, parallel-arm clinical study. Patients with a diagnosis of RA, moderate or high clinical disease activity (CDAI>10) despite conventional synthetic (cs)DMARD(s) therapy for ≥3 months, naïve to biological (b) and targeted synthetic (ts)DMARDs therapy and a maximum of 2 swollen joints (out of 44 joints) will be included and randomized to one of the following two strategic arms: 1. Clinical decision strategy: All patients receive a TNF-alpha blocker while continuing background csDMARD(s) therapy. If a CDAI ≤10 is not achieved after 12 weeks, patients are switched to a bDMARD or tsDMARD. The decision on which b/tsDMARD to use at week 12 is at the discretion of the investigator. 2. Clinical plus ultrasound-based decision strategy. All patients in this group will be evaluated by ultrasound at 44 joints. In case of clinically-verified plus ultrasound verified inflammation, patients will receive a TNF-alpha blocker while continuing background csDMARD(s) therapy. If a CDAI ≤10 is not achieved after 12 weeks, patients are again evaluated by ultrasound at 44 joints. In case clinically-verified plus ultrasound-verified inflammation is present, patients are switched to a bDMARD or tsDMARD. The decision on which b/tsDMARD to use is at the discretion of the investigator. In case clinically-verified plus ultrasound-verified inflammation is absent, patients receive step-up pain therapy while background csDMARD(s) will be continued. Sample size 110 patients Time plan - Total duration of the study: 42 months - Active phase for each patient: 48 weeks (24 weeks for the interventional treatment strategy and 24 weeks for follow-up visit) - Recruitment: 30 months
This study is set up as a phase I prospective, single center, device interventional pilot study carried in office setting under local anesthesia. It will assess the tolerance and safety of target fusion ablation of prostate cancer tumors using Laser Induced Thermal Therapy (TFA-LITT) guided by fusion imaging in men 50 to 80 years of age with low to intermediate risk prostate cancer Prostate Cancer is currently managed with in a discrete fashion where patients either enroll in active surveillance protocols (No intervention) or undergo full intervention via whole gland treatments - most commonly radical surgery or radiation. These treatments have not shown definitive gains in all cause survival and not uncommonly harbor undesirable adverse effects, most notably: impotency and incontinence. Such events elicit significant and noticeable changes on a male lifestyle and for most prostate cancer tumors are considered overtreatment. This study aims to evaluate the use of TFA-LITT in the office setting under local anesthesia - greatly decreasing patient perioperative surgical risk - focused on the organ sparing cancer lesion ablation, where organ function is preserved. The fundamental objective is to determine the tolerance and safety of TFA-LITT in men with low to intermediate risk prostate cancer, successful performed in the outpatient office-based setting under local anesthesia directed by fusion imaging. Secondary objectives include: 1-Biopsy proven cancer control of ablated areas 12 months after procedure; 2-Uroflowmetry and urinary function Patient Reported Outcome Measures (PROMs) at one, three, six, nine and 12 months; 3- Sexual function Patient Reported Outcome Measures (PROMs) at one, three, six, nine and 12 months; 4- MRI changes of ablated area one, three and 12 months after TFA-LITT; 5- Absence or presence of ejaculation after TFA-LITT.
This study aims to investigate the accuracy and viability of transcutaneous laryngeal ultrasound (US) in detecting impairments of vocal fold movement in people with neurological disorders. The accuracy and viability of laryngeal US compared with reference standard fibreoptic nasendoscopic examination (FNE) will be evaluated. The study also includes measurements of clinician reliability in US image acquisition and interpretation, and assess the acceptability of US assessment to people with neurological disorders. Data will be used to assess the ability of US to detect other laryngeal pathology, and to calculate the sample size required for a validation study.
This study seeks to define the ultrasound profile of patients with COVID-19, and document the progression of these ultrasound findings to develop prognostication and clinical decision instruments that can help guide management of patient with COVID-19. Primary aims include the development of ARDS, refractory hypoxemia, acute cardiac injury, pulmonary embolism, pneumothorax or death. Secondary aims include potential change in CT and plain film utilization given the use of POCUS, as well as emergency department and inpatient LOS (length of stay).
The aim of this study was to investigate the added value of contrast-enhanced ultrasound (CEUS) for differentiating low risk patients with breast nodules categorized as 4A using the Breast Imaging Reporting and Data System (BI-RADS).
The purpose of this study is to evaluate reliability of Point-of-Care ultrasound evaluation performed by general practitioners.
We hypothesize that recovered COVID-19 patients suffer long term cardiovascular and pulmonary complications, which can be detected by point of care ultrasound. The goal is to comprehensively delineate the long term cardiovascular and pulmonary ultrasound findings in recovered COVID-19 patients, identify risks factors for prolonged heart/lung injury, evaluate long term effects of applied treatment, and assess late medication/vaccine side effects in COVID-19 patients.
Sonazoid as a new generation of ultrasound contrast agent.This study based on the features of Sonazoid specific angiography and high mechanical index,the role of Sonazoid in the differential diagnosis of breast benign and malignant tumors was explored.
To assess the prognostic performance of an early global LUS score with respect to the mortality in ICU and duration of ventilation.
