Active clinical trials for "Disease Progression"

The present case-control study is designed to investigate the disease characteristics of IR-CAD by comparing the demographics, clinical features, lab results, imaging findings, and prior treatment between 20 patients with IR-CAD and 10 patients with AS-CAD.

The CATALINA study is a prospective interventional cohort study embedded within CICERO (Collaboration In COPD ExaceRbatiOns, a European Respiratory Society supported Clinical Research Collaboration), designed to collect standardised, longitudinal clinical data and biological samples in 20 pan-European centres.

The goal of this observational study is to assess in the cohort of CLL patients enrolled in the front-line GIMEMA LLC1114 study who discontinued ibrutinib the time to subsequent treatment. The main question it aims to answer is: • The 12 and 24-month TTNT measured from the time of ibrutinib discontinuation due to reasons other than CLL progression, Richter syndrome, malignancy or death, or lost to the follow-up. Participants will be observed for the duration of the study.

In this study, the investigator would conduct an ambispective cohort study to build a prediction model of HCV-related disease after DAAs.

The purpose of the study is to prospectively assess longitudinal changes in biomarkers (MECP2, potential biomarkers of target engagement and disease activity) in cerebrospinal fluid (CSF) and blood; characterize longitudinal changes in performance on clinical scales (clinician-reported measures of neurodevelopment and functioning) and caregiver-reported outcome assessments (communication, gastrointestinal, social-emotional-adaptive behavioral measures); evaluate longitudinal changes in caregiver-reported health-related quality-of-life measures; and assess the frequency, type, and severity of seizures over time.

Objective: To determine the effectiveness of proficiency based inter-professional communication training in an online environment on medical student's use of the ISBAR (Identify, Situation, Background, Assessment, Recommendation) communication escalation protocol in the deteriorating patient Setting: The study will be conducted in University College Cork, Ireland. Participants: Fifth year medical students, who are scheduled to undertake ISBAR training as part of the National Early Warning Score (NEWS) programme. Intervention: Participants will be prospectively randomized to one of three groups for training before undertaking a performance assessment of an ISBAR communication relevant to a deteriorating patient in a low fidelity simulation environment: HSE group (the national e-learning programme only); S group (national e- learning plus access to online scenarios and facilitator when requested) and PBP group (national e-learning plus access to online scenarios training course with in-built proficiency-based progression, and facilitator when requested). Main outcome and measures: A proficiency benchmark on the performance of ISBAR communication in the context of an acutely deteriorating patient.

To see if an extract of green tea can affect certain markers of breast cancer and breast cancer progression in women with a recent biopsy positive for cancer and who are scheduled for surgery.

Importance: Clinical communication is an important source of medical error and preventable adverse events. Objective: To determine the effectiveness of proficiency-based progression (PBP) simulation training for ISBAR (Identify, Situation, Background, Assessment, Recommendation) communication in the deteriorating patient. Setting: The study will be conducted in University College Cork, Ireland. Participants: Third year undergraduate nursing and fifth year medical students, who are scheduled to undertake ISBAR training as part of the National Early Warning Score (NEWS) programme. Intervention: Participants will be prospectively randomized to one of three groups before undertaking a performance assessment of an ISBAR communication relevant to a deteriorating patient in a high fidelity simulation laboratory: HSE group (the national e-learning programme only); S group (national e- learning plus simulation training) and PBP group (national e-learning plus proficiency-based progression simulation). Main outcome and measures: A proficiency benchmark on the performance of ISBAR communication in the context of an acutely deteriorating patient.

Multiple system atrophy (MSA) is a rare and fatal neurodegenerative disease characterised by a variable combination of parkinsonism, cerebellar impairment and autonomic dysfunction. The neuropathological hallmark is the accumulation of alpha-synuclein in oligodendrocytes. While some symptomatic treatments exist, neuroprotective treatments for MSA remain an urgent, unmet need. Moreover, at present there is not a single surrogate biomarker of MSA which could be used to inform clinical trials. This study seeks to characterise the natural history of MSA on a panel of candidate biomarkers, pre-selected for being putative surrogates of the underlying neurodegenerative process

Identifying the critical lesion of coronary artery disease and determining the interventional plan are significant for reducing adverse cardiovascular adverse events. The assessment of critical lesion requires the consideration of plaque morphology, tissue composition, and endometrial stress which leading to rupture. In summary, accurate assessment of critical lesions has high application value. In this study, patients with critical coronary artery disease were divided into two groups: an accurate assessment group and a simple assessment group, with the aim to compare the diagnosis and treatment efficiency as well as prognosis, potential cardiovascular risk, possible "excessive" intervention.
