BACKGROUND: Obesity affects a third of adults in the US and results in an increased risk of cardiovascular mortality. While the mechanisms underlying this increased risk are not well understood, animal models of obesity have shown direct effects on the heart such as steatosis and fibrosis, which may affect cardiac function. However, the effect of obesity on cardiac function in animal models is not well-defined. We hypothesized that diet-induced obesity in mice reduces strain, torsion, and synchrony in the left ventricle (LV).
METHODS: Ten 12-week-old C57BL/6 J mice were randomized to a high-fat or low-fat diet. After 5 months on …

The chromatin remodelling protein ATRX is associated with the rare genetic disorder ATR-X syndrome. This syndrome includes developmental delay, cognitive impairment, and a variety of skeletal deformities. ATRX plays a role in several basic chromatin-mediated cellular events including DNA replication, telomere stability, gene transcription, and chromosome congression and cohesion during cell division. We have used a loss-of-function approach to directly investigate the role of Atrx in the adult skeleton in three different models of selective Atrx loss. We specifically targeted deletion of Atrx to the forelimb mesenchyme, to cartilage and to bone-forming osteoblasts. We previously demonstrated that loss of ATRX …

The Ciliary Protein Cystin Forms A Regulatory Complex With Necdin To Modulate Myc Expression, Maoqing Wu, Chaozhe Yang, Binli Tao, Su Bu, Lisa Guay-Woodford
Pediatrics Faculty Publications
Cystin is a novel cilia-associated protein that is disrupted in the cpk mouse, a well-characterized mouse model of autosomal recessive polycystic kidney disease (ARPKD). Interestingly, overexpression of the Myc gene is evident in animal models of ARPKD and is thought to contribute to the renal cystic phenotype. Using a yeast two-hybrid approach, the growth suppressor protein necdin, known to modulate Myc expression, was found as an interacting partner of cystin. Deletion mapping demonstrated that the C-terminus of cystin and both termini of necdin are required for their mutual interaction. Speculating that these two proteins may function to regulate gene expression, …

Pediatrics Faculty Publications
The main purpose of this study was to address gaps in existing research by examining the relationship between academic performance and attention problems with juvenile firesetting. Two datasets from the Achenbach System for Empirically Based Assessment (ASEBA) were used. The Factor Analysis Dataset (N = 975) was utilized and results indicated that adolescents who report lower academic performance are more likely to set fires. Additionally, adolescents who report a poor attitude toward school are even more likely to set fires. Results also indicated that attention problems are predictive of self-reported firesetting. The National Survey Dataset (N = 1158) …

Student and Faculty Publications
Invasive pulmonary aspergillosis is a rare and fatal complication in patients with cystic fibrosis (CF) who lack concomitant risk factors. The few documented cases in children have all resulted in deaths during hospitalisation. We present the case of a 12-year-old boy with CF who was admitted for an exacerbation which was unresponsive to antibiotic therapy. The findings on imaging raised concerns about a possible fungal infection. As a result, voriconazole therapy was started prior to his respiratory deterioration. He was later found to be β-D glucan and Aspergillus Ag galactomannan positive confirming the suspicion for invasive pulmonary aspergillosis. Three months …

BACKGROUND: Frequent painful vaso-occlusive crises (VOCs) were associated with mortality in the Cooperative Study of Sickle Cell Disease (CSSCD) over twenty years ago. Modern therapies for sickle cell anemia (SCA) like hydroxyurea are believed to have improved overall patient survival. The current study sought to determine the relevance of the association between more frequent VOCs and death and its relative impact upon overall mortality compared to other known risk factors in a contemporary adult SCA cohort.
METHODS: Two hundred sixty four SCA adults were assigned into two groups based on patient reported outcomes for emergency department (ED) visits or hospitalizations …

The basal ganglia have traditionally been viewed as motor processing nuclei; however, functional neuroimaging evidence has implicated these structures in more complex cognitive and affective processes that are fundamental for a range of human activities. Using quantitative meta-analysis methods we assessed the functional subdivisions of basal ganglia nuclei in relation to motor (body and eye movements), cognitive (working-memory and executive), affective (emotion and reward) and somatosensory functions in healthy participants. We document affective processes in the anterior parts of the caudate head with the most overlap within the left hemisphere. Cognitive processes showed the most widespread response, whereas motor processes …

Techniques For The Isolation Of High-Quality Rna From Cells Encapsulated In Chitosan Hydrogels, Claire Yu, Stuart Young, Valerio Russo, Brian G. Amsden, Lauren E. Flynn
Paediatrics Publications
Extracting high-quality RNA from hydrogels containing polysaccharide components is challenging, as traditional RNA isolation techniques designed for cells and tissues can have limited yields and purity due to physiochemical interactions between the nucleic acids and the biomaterials. In this study, a comparative analysis of several different RNA isolation methods was performed on human adipose-derived stem cells photo-encapsulated within methacrylated glycol chitosan hydrogels. The results demonstrated that RNA isolation methods with cetyl trimethylammonium bromide (CTAB) buffer followed by purification with an RNeasy® mini kit resulted in low yields of RNA, except when the samples were preminced directly within the buffer. In …

For decades, researchers have investigated how events in the prenatal period impact women and their infants. These studies, particularly by researchers in the medical, neuroscience, and behavioral science fields, led to discoveries of important information regarding the prenatal events that were strongly associated with mortality (or death) and morbidity (or incidences of injury, pathology and abnormalities/anomalies, and neurobehavioral sequelae) in the neonatal and infancy periods. Among the many common findings from early research studies, two are particularly noteworthy. First, maternal and fetal risk conditions arising in the prenatal period do not do so in isolation. Sameroff and Chandler characterized this …

Diagnosis, Treatment And Follow-Up In Four Children With Biotinidase Deficiency From Pakistan, Bushra Afroze, Mohammad Wasay
Department of Medicine
Biotinidase deficiency is an inherited disorder in which the vitamin biotin is not recycled. If untreated, affected individuals develop neurological and cutaneous symptoms. Untreated individuals with biotinidase deficiency either succumb to disease or are left with significant morbidity. We describe clinical course and follow-up of 4 children from Pakistan. All 4 presented with classical symptoms of biotinidase deficiency and responded dramatically to oral biotin within days to weeks. Biotinidase deficiency is reported in Pakistani children from different part of world, however; there is no such report from Pakistan. This highlights lack of awareness of biotinidase deficiency among physicians in Pakistan

Department of Medicine
Primary neoplasms of the respiratory tract are rarely encountered in the paediatric population. Inflammatory myofibroblastic tumour (IMT) is a rare soft tissue mesenchymal tumour but a distinct disease entity accounting for less than 1% of all primary lung tumours. We report a case of a 10-year-old boy who presented with respiratory failure and left lung collapse. On flexible fiberoptic bronchoscopy, a pedunculated mass in the lower part of the trachea originating from the left main stem bronchus was identified. The patient subsequently underwent a left-sided pneumonectomy with complete resection of the mass. The histopathological analysis was consistent with IMT. Two …

In utero exposure to opiates may affect autonomic functioning of the fetus and newborn. We investigated heart rate variability (HRV) as a measure of autonomic stability in prenatal opiate-exposed neonates (n = 14) and in control term infants (n = 10). Electrocardiographic data during both non-nutritive and nutritive sucking were evaluated for RR intervals, heart rate (HR), standard deviation of the consecutive RR intervals (SDRR), standard deviation of the differences of consecutive RR intervals (SDDRR), and the power spectral densities in low and high frequency bands. In controls, mean HR increased significantly, 143-161 per min (p = …

Fire is the rapid oxidation of a material in the exothermic chemical process of combustion, releasing heat, light, and various reaction products. Fire is intriguing and therefore something that will attract a curious child from an early age.
In 2010, the United States fire department responded to 44,900 fires started by someone, usually a child, playing with fire. These fires caused 90 civilian deaths, 890 civilian injuries, and $210 million in direct property damage. Preschoolers and kindergartners are most likely to start these fires, while playing with matches or lighters and most likely to die in these fires. Most fire-play …

BACKGROUND:
Hepatitis E virus (HEV) infection has become relevant to blood transfusion practice because isolated cases of blood transmission have been reported and because HEV has been found to cause chronic infection and severe liver disease in immunocompromised patients.
STUDY DESIGN AND METHODS:
We tested for immunoglobulin (Ig)G and IgM antibodies to the HEV and for HEV RNA in 1939 unselected volunteer US blood donors. Subsequently, we tested the same variables in pre- and serial posttransfusion samples from 362 prospectively followed blood recipients to assess transfusion risk.
RESULTS:
IgG anti-HEV seroprevalence in the total 1939 donations was 18.8%: 916 of …
