BACKGROUND Patients with systemic sclerosis (SSc) may develop exercise intolerance due to musculoskeletal involvement, restrictive lung disease, left ventricular dysfunction, or pulmonary vasculopathy (PV). The latter is particularly important since it may lead to lethal pulmonary arterial hypertension (PAH). We hypothesized that abnormalities during cardiopulmonary exercise testing (CPET) in p...
BACKGROUND Chronic heart failure is an important cause for morbidity and mortality in adults with congenital heart disease (ACHD). While NT-proBNP is an established biomarker for heart failure of non-congenital origin, its value in ACHD has limitations. Asymmetrical dimethylarginine (ADMA) correlates with disease severity and independently predicts adverse clinical events in heart failure of no...
STUDY OBJECTIVE To develop an integrated strategy for the identification and subsequent management of high-risk patients in order to reduce both morbidity and mortality. DESIGN Prospective consecutive series in which all patients underwent cardiopulmonary exercise (CPX) testing. SETTING CPX laboratory and level 3 ICU and high-dependency unit (HDU) of a metropolitan teaching hospital. PATI...
From 2010 to 2012, large outbreaks of EV-A71-related- hand foot and mouth disease (HFMD) occurred annually in China. Some cases had neurological complications and were closely associated with fatal cardiopulmonary collapse, but not all children with central nervous system (CNS) involvement demonstrated a poor prognosis. To identify which patients and which neurological complications are more li...
Use of an inspiratory impedance valve has recently been shown to increase the efficacy of standard and active compression-decompression cardiopulmonary resuscitation. We evaluated the effects of a prototypic impedance valve on the relationship between the active decompression and intra-thoracic pressure using a mechanical model lung system. Intermittent impedance to inspiratory flow of respirat...
BACKGROUND To decrease the surgical trauma in heart procedures, minimally invasive (MI) techniques were alternatively introduced. OBJECTIVE To compare MI surgical access with median sternotomy (MS) for the treatment of mitral valve (MV) disease and atrial septal defect (ASD). METHODS Forty patients underwent surgery for correction of MV disease or ASD. Patients were divided into group A (GA...
BACKGROUND Emergencies can occur at any time during pregnancy. In addition to obstetricians and midwives, anesthesiologists should also be familiar with pregnancy-related emergencies. The aim of this study was to assess the basic and advanced knowledge regarding the management of pregnancy-related emergencies of anesthesiologists. METHODS An anonymous questionnaire was distributed to anesthes...
The hypoxia-inducible factors (HIFs; isoforms HIF-1α, HIF-2α, HIF-3α) mediate many responses to hypoxia. Their regulation is principally by oxygen-dependent degradation, which is initiated by hydroxylation of specific proline residues followed by binding of von Hippel-Lindau (VHL) protein. Chuvash polycythemia is a disorder with elevated HIF. It arises through germline homozygosity for hypomorp...
Background—Cardiopulmonary exercise testing is often used to evaluate exercise capacity in adults with congenital heart disease including women who are considering pregnancy. The relationship between cardiopulmonary exercise testing parameters and pregnancy outcome has not been defined. Methods and Results—We conducted a multicenter retrospective observational study of women with congenital hea...
BACKGROUND Neurodevelopmental delays in motor skills and white matter (WM) injury have been documented in congenital heart disease and after pediatric cardiac surgery. The lack of a suitable animal model has hampered our understanding of the cellular mechanisms underlying WM injury in these patients. Our aim is to identify an optimal surgical strategy for WM protection to reduce neurological in...
