Brain injury and neurodevelopmental outcomes in children undergoing surgery for congenital heart disease.

Objectives: Brain injury is commonly seen on magnetic resonance imaging in infants with complex congenital heart disease. The impact of perioperative brain injury on neurodevelopmental outcomes is not well understood. We evaluate the association of brain injury and other markers on neurodevelopmental outcomes in patients undergoing surgery for congenital heart surgery during infancy.

Determinants of neurological outcome in neonates with congenital heart disease following heart surgery.

Background: The objective was to determine the association between perioperative risk factors and brain imaging abnormalities on neurologic outcome in neonates with hypoplastic left heart syndrome (HLHS) or d-Transposition of the great arteries (d-TGA) who underwent cardiac surgery including cardiopulmonary bypass.

Methods: A retrospective analysis of neonates with HLHS or d-TGA undergoing cardiac surgery including cardiopulmonary bypass between 2009 and 2017 was performed. Perioperative risk factors and Andropoulos' Brain Injury Scores from pre- and postoperative brain magnetic resonant images (MRI) were correlated to outcome assessments on patients between 5 and 23 months of age.

Prenatal Diagnosis and Postnatal Outcome of Eight Cases with Criss-Cross Heart - A Multicenter Case Series.

Objective:  Criss-cross heart (CCH) is a rare congenital cardiac defect defined by crossing of ventricular inflow streams contributing to less than 0.1 % of all congenital heart anomalies. Due to its rarity and complexity, prenatal diagnosis in these patients remains challenging.

Atrial and Ventricular Deformation Analysis in Normal Fetal Hearts Using Two-Dimensional Speckle Tracking Echocardiography.

Objective: Two-dimensional speckle tracking echocardiography (2D-STE)-based strain values of the left and the right ventricle have been established; however, less is known about atrial deformation. The aim of our study was to assess both atrial strain and ventricular strain using 2D-STE in a cardiac 4-chamber view and to investigate the effect of possible influencing factors such as gestational age.

Methods: Fetal echocardiography was performed on a Toshiba Aplio 500 ultrasound system.

Anaemia is associated with severe RBC dysfunction and a reduced circulating NO pool: vascular and cardiac eNOS are crucial for the adaptation to anaemia.

Anaemia is frequently present in patients with acute myocardial infarction (AMI) and contributes to an adverse prognosis. We hypothesised that, besides reduced oxygen carrying capacity, anaemia is associated with (1) red blood cell (RBC) dysfunction and a reduced circulating nitric oxide (NO) pool, (2) compensatory enhancement of vascular and cardiac endothelial nitric oxide synthase (eNOS) activity, and (3) contribution of both, RBC dysfunction and reduced circulatory NO pool to left ventricular (LV) dysfunction and fatal outcome in AMI. In mouse models of subacute and chronic anaemia from repeated mild blood loss the circulating NO pool, RBC, cardiac and vascular function were analysed at baseline and in reperfused AMI.

Red Blood Cell Function and Dysfunction: Redox Regulation, Nitric Oxide Metabolism, Anemia.

Significance: Recent clinical evidence identified anemia to be correlated with severe complications of cardiovascular disease (CVD) such as bleeding, thromboembolic events, stroke, hypertension, arrhythmias, and inflammation, particularly in elderly patients. The underlying mechanisms of these complications are largely unidentified. Recent Advances: Previously, red blood cells (RBCs) were considered exclusively as transporters of oxygen and nutrients to the tissues.

MicroRNA-205, a novel regulator of the anti-apoptotic protein Bcl2, is downregulated in prostate cancer.

Decreased expression of the microRNA miR-205 has been observed in multiple tumour types due to its role in the epithelial to mesenchymal transition, which promotes metastasis. We determined the expression of miR-205 in 111 archival samples of prostate carcinoma and found it to be strongly reduced in most samples, with a median expression level of 16% in comparison to benign tissue from the same patient. Lower miR-205 expression correlated significantly with tumour size and miR-205 levels decreased with increasing Gleason score from 7a=3+4 to 8=4+4.
