TAVI children

Coarctation of the aorta (CoA) is a relatively common congenital heart anomaly, and bicuspid aortic valve (BAV) is a common congenital heart disease that coexists with CoA. In larger children and adults with CoA, transcatheter intervention has gained acceptance, but for surgical high-risk patients with aortic stenosis, the use of transcatheter aortic valve implantation (TAVI) has been established. Recently, although favorable data have been reported for TAVI when treating BAV, simultaneous transcatheter intervention for CoA and BAV will prove to be a challenge because of the unique anatomy involved requires multiple procedural steps and also has problems of site access...

BACKGROUND: Water-related injuries and fatalities pose serious public health issues, especially to African American youth, a demographic group that drowns at disproportionately high rates. AIM: The purpose of this study was to determine if a social marketing intervention targeting the parents and guardians of inner-city youth (U.S. Midwest) could positively influence their perceptions concerning water safety. METHOD: Researchers employed a quasi-experimental design using matched pairs to evaluate the intervention...

Lower vagal activity is associated with psychopathology independent of age. Research suggests that alterations of vagal activity precede the development of psychopathology. The present review aimed to quantify sex differences in vagal activity in children and adolescents. Studies reporting on sex differences on measures of vagally-mediated heart rate variability derived from short-term recordings under resting conditions in boys and girls were included. Drawing on data from more than 5,000 children and adolescents, we provide evidence that healthy young girls display lower vagal activity and greater mean heart rate compared to boys, a finding that may have implications for risk associated with the development of internalizing psychopathology and somatic ill-health...

Neural stem/progenitor cells (NPCs) generate new neurons in the brain throughout an individual's lifetime in an intricate process called neurogenesis. Neurogenic alterations are a common feature of several adult-onset neurodegenerative diseases. The neuronal ceroid lipofuscinoses (NCLs) are the most common group of inherited neurodegenerative diseases that mainly affect children. Pathological features of the NCLs include accumulation of lysosomal storage material, neuroinflammation and neuronal degeneration, yet the exact cause of this group of diseases remains poorly understood...

BACKGROUND: Animal models show that prenatal bisphenol A (BPA) exposure leads to sexually dimorphic disruption of the neuroendocrine system in offspring, including the hypothalamic-pituitary-adrenal (HPA) neuroendocrine system, but human data are lacking. In humans, prenatal BPA exposure is associated with sex-specific behavioural problems in children, and HPA axis dysregulation may be a biological mechanism. The objective of the current study was to examine sex differences in associations between prenatal maternal urinary BPA concentration and HPA axis function in 3 month old infants...

Whereas significant advances have been made in understanding how exposure to early adversity "gets under the skin" of children to result in long term changes in developmental outcomes, the processes by which positive social relationships become biologically embedded remain poorly understood. The aim of this study was to understand the pathways by which maternal and infant social environments become biologically embedded in infant cortisol reactivity. Two hundred seventy-two pregnant women and their infants were prospectively assessed during pregnancy and at 6 months postpartum...

BACKGROUND: Clinically significant psychological distress in pregnancy is common, with epidemiological research suggesting that between 15 and 25 % of pregnant women experience elevated symptoms of stress, anxiety, and depression. Untreated psychological distress in pregnancy is associated with poor obstetrical outcomes, changes in maternal physiology, elevated incidence of child physical and psychological disorders, and is predictive of maternal postpartum mood disorders. Despite the wide-ranging impact of antenatal psychological distress on mothers and their children, there is a gap in our knowledge about the most effective treatments that are available for psychological distress experienced in pregnancy...

Studies investigating the possible benefits of transcranial direct current stimulation on left dorsolateral prefrontal cortex in children and adolescents with attention-deficit hyperactivity disorder (ADHD) have not been performed. This study assesses the effect of transcranial direct current stimulation in children and adolescents with ADHD on neuropsychological tests of visual attention, visual and verbal working memory, and inhibitory control. An auto-matched clinical trial was performed involving transcranial direct current stimulation in children and adolescents with ADHD, using SNAP-IV and subtests Vocabulary and Cubes of the Wechsler Intelligence Scale for Children III (WISC-III)...

Sphingolipids are sphingosine-based phospholipids, which are present in the plasma and endomembranes of many eukaryotic cells. These lipids are involved in various cellular functions, including cell growth, differentiation, and apoptosis. In addition, sphingolipid and cholesterol-enriched membrane microdomains (also called "lipid rafts") contain a set of proteins and lipids, which take part in the signaling process in response to intra- or extracellular stimuli. Recent findings suggest that sphingolipids, especially glucosylceramide, play a critical role in inducing encystation and maintaining the cyst viability in Giardia...

Exposure to airborne manganese (Mn) has been associated with neurotoxic effects, including motor and cognitive deficits. The main deficits related to excessive exposure to Mn are predominantly the dysfunction of fronto-striatal and dopaminergic circuits observed in animal experimental studies, which are involved in attention, working memory and motor function. The present study aims to assess the association between elevated Mn exposure and performance on executive function and attention neuropsychological tests in children living in two communities near a ferro-manganese alloy plant...

OBJECTIVES: To determine if attitudes associated with body checking, emotional empathy, and aggression differ between players in body checking and non-body checking hockey leagues and to determine the influence of these attitudes on injury rates. DESIGN: Prospective cohort. SETTING: Participants were randomly recruited by team from the Calgary Minor Hockey Association at the beginning of the 2006-2007 season. PARTICIPANTS: There were 283 participants from Pee Wee (aged 11-12 years), Bantam (aged 13-14 years), and Midget (aged 15-16 years) teams...

PURPOSE: Pediatric central venous catheters (CVCs) traditionally have been placed surgically, guided by anatomic landmarks. Increasingly, interventional radiology services are inserting CVCs using ultrasound image guidance. This study compares the frequency of delayed complications in CVCs placed surgically or radiologically in a pediatric oncology population. METHODS: Data on CVCs placed in one academic institution over 10 years were collected and analyzed retrospectively...

The authors present the normative data of a computerized test (TAVIS) that address visual attention in children and adolescents being the first neuropsychological instrument as such devised and developed in Brazil. Selective, alternate and sustained attention aspects are evaluated through three different tasks. Omission and action errors as well as time reaction are evaluated. The advantages and limitations of the test are commented.
