This is a single-arm, multicentre study that aims to assess whether Radiomics combining multiparametric MRI and clinical data could be a good predictor of the responses to neoadjuvant chemotherapy in Breast Cancer.

EBI2 is a risk gene for inflammatory bowel diseases (rs9557195). Patients of the Swiss IBD cohort study have been genotyped for the allelic status of EBI2. The investigators will test the influence of rs9557195 genoty (TT or CC allel), inflammatory activity and current treatment (infliximab vs. vedolizumab) on expression and activity of EBI2 on blood lymphocytes, mRNA expression of EBI2 and UBAC2 (located on the opposite DNA strand of EBI2) and activity of lymphocytes on a migraton assay.

To generate pilot data to investigate the potential to use in vivo iron- and neuromelanin-quantification as imaging tools for the diagnostic evaluation of movement disorders with predominant dystonia / parkinsonism. To this end we are planning to compare the MR imaging neuromelanin and iron-pattern and content in midbrain, striatum and further brain structures in clinically similar entities and respective, sex- and age-matched healthy controls.

RIKADA is a prospective study performing systematic family screening including clinical and genetic testing in pediatric patients with primary cardiomyopathy and their first-degree relatives with the aim to facilitate risk stratification.

Objectives: to evaluate the current diagnostic and therapeutic approaches for sepis-associated disseminated intravascular coagulation (DIC) in a large prospective registry. Design: prospective, multicenter, international registry. Study population: patients 18 years or older with severe infection to be potentially associated with DIC will be eligible for the study. The clinical visits and monitoring of the patients will follow local routine practices. No specific imaging tests or laboratory evaluations will be required and patients will be evaluated and treated according to local policy. All the involved centers will be asked to update information on included patients at 2, 4, 6, 8, 10 and 28 days after severe infection diagnosis. Study outcomes: The primary outcome of the study is the development of DIC. Secondary outcomes are thrombotic (arterial and venous) and bleeding events, overall mortality at 28 days. Study sample, feasibility, and analysis plan: We plan to enroll a minimum of 1000 patients.

Stroke can be ischemic, hemorrhagic, or both. Early recognition and treatment of pediatric stroke are critical in optimizing long-term functional outcomes, reducing morbidity and mortality, and preventing recurrent stroke. Neuroimaging plays a vital role in achieving this goal. Neuroimaging is usually the first step in diagnosis, helping discriminate between ischemic/hemorrhagic strokes and also in the identification of underlying potential causes. Multiparametric magnetic resonance imaging (MRI) plays a crucial role in assessing pediatric cerebral stroke including diffusion-weighted imaging (DWI), susceptibility weighted imaging (SWI) and magnetic resonance angiography (MRA).

Focusing on patients with diabetes complicated with pulmonary infection, the purpose of this study is: 1) to identify the epidemiology, etiologic spectrum and status of diagnosis and treatment; 2) to develop a symptom score scale , clarify the risk factors and create a precise warning model; 3) to develop a rapid detection of pathogen of lower respiratory infection, to establish clinical pathways of early diagnosis and treatment of diabetes complicated with pulmonary infections (including bacterial, tuberculosis and fungal infections) and then make an application in clinic.

Among patients admitted to the intensive care unit (ICU), early recognition of those with the highest risk of death is of paramount importance. Since clinical judgment is sometimes uncertain biomarkers could provide additional information likely to guide critical illness management. We want to evaluate the prognostic value of leucocyte surface expression of CD64. Blood samples for CD64 biomarker measurement will be obtained daily during the patient's hospitalization. The primary outcome was all-cause death at D28 after admission

Background: Patients at increased risk for sudden cardiac death (SCD) may receive an implantable cardioverter defibrillator (ICD). The primary criterion for a primary prevention ICD implantation is a left ventricular ejection fraction (LVEF) below 35%, but refinement of ICD criteria is important since only a small proportion of ICD patients receives appropriate device therapy (ATP or a shock) during follow-up. Post-extrasystolic potentiation (PESP) may be a new risk marker for SCD. PESP is defined as a temporary increase in contractility that follows an extrasystolic beat (ESB) and is associated with myocardial calcium handling. In heart failure, changes in calcium homeostasis may lead to afterdepolarisations and thus predispose for SCD. PESP can be measured indirectly and non-invasively as post-extrasystolic blood pressure potentiation (PESP-BP). Abnormal PESP-BP was previously found to be an independent predictor of increased mortality in post-myocardial infarction patients with a reduced LVEF. However, it is unknown if this increased mortality in heart failure patients with abnormal PESP-BP is caused by an increased risk of SCD. Hypothesis: The investigators hypothesize that PESP-BP might be a new predictor of the occurrence of SCD, and can be used to enhance patient selection for primary prevention ICD therapy. Design: During scheduled device replacement ESB with various extrasystolic and post-extrasystolic coupling intervals will be evoked by electrical stimulation via the right atrial and ventricular device leads of the patient. Throughout the stimulation study blood pressure will be measured non-invasively a continuous electrocardiogram will be recorded. Either before or after the procedure, patients will undergo a 30-minutes assessment of spontaneous ESB, again with blood pressure and ECG recordings. Study population: 30 patients who are scheduled for device replacement or reposition, are eligible for this study; (1) 10 ICD patients who previously received appropriate device therapy (ADT); (2) 10 ICD patients who are free from ADT and (3) 10 dual-chamber pacemaker patients (control group). Outcomes: (1) Evoked PESP-BP (i.e. blood pressure differences between baseline, ESB and post-ESB); (2) Spontaneous PESP-BP (i.e. blood pressure differences between baseline, ESB and post-ESB); (3) Timing parameters (in ms): the basic cycle length interval; Extra-systolic interval (ESI); Post-extrasystolic interval (PESI).

Pneumonia continues to be a leading cause of death in children under five years of age worldwide. Many studies have evaluated clinical signs and symptoms that may predict pneumonia. A recent meta-analysis found that no singular physical exam finding predicted pneumonia. The World Health Organization (WHO) Criteria diagnose pneumonia based on fast breathing; however, tachypnea has not been shown to strongly predict pneumonia. This study will evaluate accuracy of clinical history, physical exam and WHO criteria, laboratory findings, and lung ultrasound compared with chest radiograph for the diagnosis of pneumonia in children under five years of age in a resource limited setting. Determining diagnostic accuracy of these findings may help derive a clinical decision rule that may more accurately predict which children have pneumonia than current WHO guidelines.
