Association between patent ductus arteriosus flow and home oxygen therapy in extremely preterm infants.

Background: Central blood flow measurements include the estimation of right and left ventricular output (RVO, LVO), superior vena cava (SVC) flow, and calculated patent ductus arteriosus (PDA) flow. We aimed to provide an overview of the maturation patterns of these values and the relationship between PDA flow and the need for home oxygen therapy.

Methods: This prospective single-center study was conducted in infants born at <26 weeks of gestation.

Long-term outcomes of intravenous fibrinolysis in central retinal artery occlusion.

Central retinal artery occlusion (CRAO) is an ophthalmologic emergency that can lead to irreversible loss of vision. Intravenous thrombolysis (IVT) has been used experimentally for its treatment. Our study aimed to evaluate the effect of emergency IVT on CRAO and its impact on visual acuity outcomes.

Adenotonsillar pathology in mucopolysaccharidoses - lysosomal storage predominates in paracortical CD63+ cells.

Despite the adenoids are regularly removed in patients with mucopolysaccharidoses (MPS), the underlying tissue and cellular pathologies remain understudied. We characterized an (immuno)histopathologic and ultrastructural phenotype dominated by lysosomal storage changes in a specific subset of adenotonsillar paracortical cells in 8 MPS patients (3 MPS I, 3 MPS II, and 2 MPS IIIA). These abnormal cells were effectively detected by an antibody targeting the lysosomal membrane tetraspanin CD63.

Detailed Phenotype of GLA Variants Identified by the Nationwide Neurological Screening of Stroke Patients in the Czech Republic.

Fabry disease (FD) is a rare X-linked disorder of glycosphingolipid metabolism caused by pathogenic variants within the alpha-galactosidase A (GLA) gene, often leading to neurological manifestations including stroke. Multiple screening programs seeking GLA variants among stroke survivors lacked detailed phenotype description, making the interpretation of the detected variant's pathogenicity difficult. Here, we describe detailed clinical characteristics of GLA variant carriers identified by a nationwide stroke screening program in the Czech Republic.

Anesthesia for cesarean delivery in the Czech Republic: a 2011 national survey.

Background: The purpose of this national survey was to determine current anesthesia practices for cesarean delivery in the Czech Republic.

Methods: In November 2011, we invited all departments of obstetric anesthesia in the Czech Republic to participate in a prospective study to monitor consecutive peripartum obstetric anesthesia procedures. Data were recorded online in the TrialDB database (Yale University, New Haven, CT).
