We were able to demonstrate a predictive value of serum HER2 (sHER2) in patients receiving trastuzumab in the neoadjuvant GeparQuattro trial. However, the role of sHER2 in patients receiving neoadjuvant therapy (NT) with lapatinib is still unclear. The neoadjuvant GeparQuinto trial compared trastuzumab vs lapatinib in addition to chemotherapy in ...

CD163 is expressed on cells of monocyte-macrophage lineage and is the main hemoglobin-haptoglobin receptor. Inflammation and monocyte activation are predisposing factors to vaso-occlusion and pulmonary hypertension, which are serious complications in sickle cell disease (SCD). Siblings of SCD patients may have the same pathophysiology without displaying symptoms. We assessed soluble ...

RESULTS: Serum neopterin levels were substantially higher ...

BACKGROUND: Fatigue is one of the most prevalent symptoms in chronic kidney disease (CKD). However, fatigue mechanisms are poorly understood due in part to nonspecific definitions. This study investigates exertional fatigue during simulated activities of daily living, focusing on oxygen delivery and utilization. STUDY DESIGN: "Explanatory" matched-cohort study. PARTICIPANTS & ...

Colchicine has been used in a number of disorders. Because colchicine is partially excreted from the kidney, there is a need for dose reduction in case of renal functional impairment. There are no data with regards to safe dosing schedule of colchicine in hemodialysis patients. We aimed to evaluate adverse ...

OBJECTIVE: Idiopathic atrial fibrillation (AF) refers to a clinically lacking cardiovascular or pulmonary disease generating the pathophysiological substrate for the arrhythmia. However, since idiopathic AF is associated with an increased event rate, it could be a harbinger of as yet undetected underlying heart disease. We studied the prevalence of coronary ...

BackgroundNormocalcemic Primary Hyperparathyroidism (PHPT-N) is a condition which may have similar long-term implications than Primary Hyperparathyroidism (PHPT); however parathyroids disorders differential diagnosis and treatment are not clearly defined. We investigated the effect of an oral peptone and an oralcalcium load on calcium-regulating hormones in PHPT-N compared to PHPT and healthy ...

Cardioembolism in paroxysmal atrial fibrillation (pxAF) is a frequent cause of ischemic stroke. Sensitive detection of pxAF after stroke is crucial for adequate secondary stroke prevention; the optimal diagnostic modality to detect pxAF on stroke units is unknown. We compared 24-hour Holter electrocardiography (ECG) with continuous stroke unit ECG monitoring ...

BACKGROUND: Left ventricular noncompaction (LVNC) is characterized by a two-layered myocardium consisting of a noncompacted inner and a compacted outer layer. The ratio of the thicknesses of these two layers is a major diagnostic criterion, which is, however, often difficult to apply in clinical practice. METHODS: Transthoracic echocardiography was performed in ...
