Analgosedierung mit Fentanyl/Midazolam nach Korrektur angeborener Herzfehler

1995

Abstract There is no standard therapy in the management of postoperative pain control following corrective cardiac surgery of congenital heart disease. Assessment in the preverbal age is difficult. In a randomized study we compared a combined treatment of fentanyl and midazolam, given as continuous infusion versus single dose application. A pain assessment score was used to measure the effectiveness of analgosedation in addition to recording nurseries observations. Fentanyl and midazolam are an appropriate combination for postoperative pain treatment. Continuous application is considered to be more effective concerning basic anxiety, cumulative dosage and to avoid volume overload in infants…

Antigen carbohydrate 125 in heart failure: Not just a surrogate for serosal effusions?

2011

Wehave readwith interest the letter CA-125andheart failure:Deja vu or “still to be seen” by Topatan B and Basaran A [1] where the authors concisely reviewed the current pathophysiological knowledgeof CA125 in heart failure (HF). As discussed by these authors, the pathogenesis of this biomarker's elevation inHF is complex andmultifactorial,with apparently different driven forces. For instances, a proinflammatory stimulus (IL-1, tumour necrosis factor-α, lipopolysaccharide) and mesothelial-induced stress appear thekeymechanisms related to the increaseof this biomarker in HF [1–5]. However, no clear evidence exists in regard to how these two mechanisms differentially participate in CA-125 elev…

Pharmacological Therapy in Children with Atrial Fibrillation and Atrial Flutter

2008

Heart rhythm disorders in children are not different, on electrocardiographic trace, from heart rhythm disorders in adults with the exception of incidence which is different according to the age. Paticularly, atrial flutter (FlA) and fibrillation (FA) are very uncommon arrhythmias in the general pediatric population. Generally atrial fibrillation and atrial flutter, in our experience, is a temporary heart rhythm disturbance connected to specifical and resovable reasons with the exception of Fontains surgical correction of congenital heart diseases or cardiopathies with dilatation of both atria. Presenting symptoms, symptom history (e.g., frequency, duration, and severity), risk assessment, …

Serum uric acid and outcomes in patients with chronic heart failure through the whole spectrum of ejection fraction phenotypes: Analysis of the ESC-E…

2021

Background: Retrospective analyses of clinical trials indicate that elevated serum uric acid (sUA) predicts poor outcome in heart failure (HF). Uric acid can contribute to inflammation and microvascular dysfunction, which may differently affect different left ventricular ejection fraction (LVEF) phenotypes. However, role of sUA across LVEF phenotypes is unknown. Objectives: We investigated sUA association with outcome in a prospective cohort of HF patients stratified according to LVEF. Methods: Through the Heart Failure Long-Term Registry of the European Society of Cardiology (ESC-EORP-HFLT), 4,438 outpatients were identified and classified into: reduced (= 50% HFpEF) LVEF. Endpoints were t…

LARP7 variants and further delineation of the Alazami syndrome phenotypic spectrum among primordial dwarfisms: 2 sisters.

2019

Abstract Alazami syndrome (AS) (MIM# 615071 ) is an autosomal recessive microcephalic primordial dwarfism (PD) with recognizable facial features and severe intellectual disability due to depletion or loss of function variants in LARP7. To date, 15 patients with AS have been reported. Here we describe two consanguineous Algerian sisters with Alazami PD due to LARP7 homozygous pathogenic variants detected by whole exome sequencing. By comparing these two additional cases with those previously reported, we strengthen the key features of AS: severe growth restriction, severe intellectual disability and some distinguishing facial features such as broad nose, malar hypoplasia, wide mouth, full li…

Home is the new gym: exergame as a potential tool to maintain adequate fitness levels also during quarantine

2020

Purpose With the coronavirus outbreak, the preventive measures include staying at home and isolation, increasing sedentary behaviours and risk for worsening of chronic diseases To explore alternative forms of home-based physical activity, the study aim was to evaluate physiological (heart rate [HR], respiratory exchange ratio [RER], oxygen consumption [ O2], energy expenditure [EE], metabolic equivalent task [MET]) and psychological (session rating of perceived exertion [sRPE], enjoyment) parameters of real (Zumba® class [ZC]) and exergame (Zumba® Fitness Rush [ZFR]) activities in relation to sex Methods Overall, 12 female (age: 24 7 ± 0 9 years) and 8 male (age: 25 3 ± 2 1 years) college s…

Nickel release after implantation of the Amplatzer occluder.

2003

Background Transcatheter closure of atrial septal defects is a new and less traumatic technique than open heart surgery. In recent years, patients with a patent foramen ovale sustaining potential paradoxical embolism have also become candidates for interventional closure devices. One of the more popular occluding devices is the Amplatzer septal occluder, which, like many other occluders, is made of nitinol. Nitinol-based alloys are widely used in medical products, for example, in orthopedics and orthodontics. However, the clinical use of nitinol, which contains 55% nickel, is still controversial because of concerns about its biocompatibility. Therefore, we examined the systemic nickel relea…

Quantification of myocardial blood flow and blood flow reserve in the presence of arterial dispersion: A simulation study

2002

Myocardial blood flow (MBF) can be quantified using dynamic T1-weighted MRI of diffusible tracers and a mathematical model of underlying vasculature. Quantification of MBF by means of T1- weighted MRI requires knowledge of the arterial input function (AIF). The AIF can be estimated from the left ventricular (LV) cavity. However, dispersion may occur between the LV and the tissue of interest because of the laminar blood flow profiles, branching of venules, and because of stenosis. To evaluate the influence of dispersion on the results of MBF quantification, a simulation study was performed. The dispersion was described as a convolution of the AIF with an exponential residue function. Synthet…

Blood urea nitrogen to creatinine ratio in acute heart failure: an old concept brought to reality?

2016

Renal dysfunction is one of the most important comorbidities in patients with chronic heart failure (HF) and frequently accentuated in the setting of acute HF (AHF).1 In either context, renal dysfunction has important clinical implications that deserve to be highlighted: (A) the added increase in risk of adverse clinical outcomes2 and (B) at greater degrees of renal failure, well evidenced therapies are lacking and current management remains mostly empirical.1 The pathophysiology of renal dysfunction in AHF is complex, multifactorial and not completely understood, which may potentially explain why patients with worsening renal function (WRF) show mixed clinical response and outcomes.1 An im…
