Introduction: Open fractures are associated with a high risk of infection. The prevention of infection is the single most important goal, influencing perioperative care of patients with open fractures. Using data from 2,500 participants with open fracture wounds enrolled in the Fluid Lavage of Open Wounds trial, we conducted a multivariable analysis to determine the factors that are associated with infections 12 months postfracture. Methods: Eighteen predictor variables were identified for infection a priori from baseline data, fracture characteristics, and surgical data from the Fluid Lavage of Open Wounds trial. Twelve predictor variables were identified for deep infection, which included …

Targeted Expression Profiling Reveals Distinct Stages Of Early Canine Fibroblast Reprogramming Are Regulated By 2-Oxoglutarate Hydroxylases, Ian C. Tobias, Mian Mian C. Kao, Thomas Parmentier, Hailey Hunter, Jonathan Lamarre, Dean H. Betts

Paediatrics Publications

Background: Ectopic expression of a defined set of transcription factors allows the reprogramming of mammalian somatic cells to pluripotency. Despite continuous progress in primate and rodent reprogramming, limited attention has been paid to cell reprogramming in domestic and companion species. Previous studies attempting to reprogram canine cells have mostly assessed a small number of presumptive canine induced pluripotent stem cell (iPSC) lines for generic pluripotency attributes. However, why canine cell reprogramming remains extremely inefficient is poorly understood. Methods: To better characterize the initial steps of pluripotency induction in canine somatic cells, we optimized an experimental system where canine fetal fibroblasts …

The Use Of Induced Pluripotent Stem Cells In Domestic Animals: A Narrative Review, Rachel A. Scarfone, Samantha M. Pena, Keith A. Russell, Dean H. Betts, Thomas G. Koch

Paediatrics Publications

Induced pluripotent stem cells (iPSCs) are undifferentiated stem cells characterized by the ability to differentiate into any cell type in the body. iPSCs are a relatively new and rapidly developing technology in many fields of biology, including developmental anatomy and physiology, pathology, and toxicology. These cells have great potential in research as they are self-renewing and pluripotent with minimal ethical concerns. Protocols for their production have been developed for many domestic animal species, which have since been used to further our knowledge in the progression and treatment of diseases. This research is valuable both for veterinary medicine as well as …

Synergistic Stabilization By Nitrosoglutathione-Induced Thiol Modifications In The Stromal Interaction Molecule-2 Luminal Domain Suppresses Basal And Store Operated Calcium Entry, Matthew J. Novello, Jinhui Zhu, Meng Qi Zhang, Qingping Feng, Peter B. Stathopulos

Paediatrics Publications

Stromal interaction molecule−1 and −2 (STIM1/2) are endoplasmic reticulum (ER) membrane-inserted calcium (Ca2+) sensing proteins that, together with Orai1-composed Ca2+ channels on the plasma membrane (PM), regulate intracellular Ca2+ levels. Recent evidence suggests that S-nitrosylation of the luminal STIM1 Cys residues inhibits store operated Ca2+ entry (SOCE). However, the effects of thiol modifications on STIM2 during nitrosative stress and their role in regulating basal Ca2+ levels remain unknown. Here, we demonstrate that the nitric oxide (NO) donor nitrosoglutathione (GSNO) thermodynamically stabilizes the STIM2 Ca2+ sensing region in a Cys-specific manner. We uncovered a remarkable synergism in this stabilization involving the …

Perfusion Bioreactor Culture Of Human Adipose-Derived Stromal Cells On Decellularized Adipose Tissue Scaffolds Enhances In Vivo Adipose Tissue Regeneration, Tim Tian Y. Han, Lauren E. Flynn

Paediatrics Publications

Tissue-engineering approaches hold promise to address the need in plastic and reconstructive surgery for new therapies that promote stable adipose tissue regeneration. Previous studies have demonstrated the potential of combining decellularized adipose tissue (DAT) scaffolds with adipose-derived stromal cells (ASCs) for volume augmentation applications. With the goal of enhancing in vivo angiogenesis and adipogenesis, this study evaluated the effects of culturing human ASCs on DAT scaffolds within a perfusion bioreactor. Using this system, the impact of both dynamic culture and hypoxic preconditioning were explored in vitro and in vivo. Initial studies compared the effects of 14 days of culture within …

Data on daily temperature and precipitation were gathered from the …

Exploring Attitudes, Subjective Norms And Perceived Behavioural Control In A Genetic-Based And A Population-Based Weight Management Intervention: A One-Year Randomized Controlled Trial, Justine R. Horne, Jason A. Gilliland, Marie Claude Vohl, Janet Madill

Paediatrics Publications

Background: Several studies demonstrate that the provision of personalized lifestyle advice, based on genetics, can help motivate individuals to engage in greater nutrition and physical activity changes compared to the provision of population-based advice. The theoretical mechanism behind this phenomenon is poorly understood. The objective of this study was to determine the impact of providing genetically tailored and population-based lifestyle advice on key constructs of the Theory of Planned Behaviour (TPB). Materials and Methods: A pragmatic, cluster randomized controlled trial (n = 140) took place at the East Elgin Family Health Team, in Aylmer, Ontario, Canada. Participants were primarily Caucasian …

Two-Week Isocaloric Time-Restricted Feeding Decreases Liver Inflammation Without Significant Weight Loss In Obese Mice With Non-Alcoholic Fatty Liver Disease, Rachel B. Wilson, Richard Zhang, Yun Jin Chen, Kia M. Peters, Cynthia G. Sawyez, Brian G. Sutherland, Krisha Patel, John P. Kennelly, Kelly Ann Leonard, René L. Jacobs, Rennian Wang, Nica M. Borradaile

Paediatrics Publications

Prolonged, isocaloric, time-restricted feeding (TRF) protocols can promote weight loss, improve metabolic dysregulation, and mitigate non-alcoholic fatty liver disease (NAFLD). In addition, 3-day, severe caloric restriction can improve liver metabolism and glucose homeostasis prior to significant weight loss. Thus, we hypothesized that short-term, isocaloric TRF would improve NAFLD and characteristics of metabolic syndrome in diet-induced obese male mice. After 26 weeks of ad libitum access to western diet, mice either continued feeding ad libitum or were provided with access to the same quantity of western diet for 8 h daily, over the course of two weeks. Remarkably, this short-term TRF …

Paediatrics Publications

BACKGROUND: Epilepsy extends far beyond seizures; up to 80% of children with epilepsy (CWE) may have comorbid cognitive or mental health problems, and up to 50% of parents of CWE are at risk for major depression. Past research has also shown that family environment has a greater influence on children's and parents' health-related quality of life (HRQOL) and mental health than epilepsy-related factors. There is a pressing need for low-cost, innovative interventions to improve HRQOL and mental health for CWE and their parents. The aim of this randomized controlled trial (RCT) is to evaluate whether an interactive online mindfulness-based intervention …

Characterization Of Mutational Status, Spheroid Formation, And Drug Response Of A New Genomically-Stable Human Ovarian Clear Cell Carcinoma Cell Line, 105c, Bart Kolendowski, Yudith Ramos Valdes, Hal Hirte, Hiroaki Itamochi, Wonjae Lee, Mark Carey, Trevor G. Shepherd, Gabriel E. Dimattia

Paediatrics Publications

Ovarian clear cell carcinoma (OCCC) is a rare subtype of gynecological cancer for which well-characterized and authenticated model systems are scarce. We provide an extensive characterization of '105C', a cell line generated from an adenocarcinoma of the clear cell histotype using targeted next-generation sequencing, cytogenetic microarrays, along with analyses of AKT/mTOR signaling. We report that that the 105C cell line is a bona fide OCCC cell line, carrying PIK3CA, PTEN, and ARID1A gene mutations, consistent with OCCC, yet maintain a stable genome as reflected by low copy number variation. Unlike KOC-7c, TOV-21G, and RMG-V OCCC lines also mutated for the …

Palmitic Acid Induces Inflammation In Placental Trophoblasts And Impairs Their Migration Toward Smooth Muscle Cells Through Plasminogen Activator Inhibitor-1, Amanda M. Rampersaud, Caroline E. Dunk, Stephen J. Lye, Stephen J. Renaud

Paediatrics Publications

A critical component of early human placental development includes migration of extravillous trophoblasts (EVTs) into the decidua. EVTs migrate toward and displace vascular smooth muscle cells (SMCs) surrounding several uterine structures, including spiral arteries. Shallow trophoblast invasion features in several pregnancy complications including preeclampsia. Maternal obesity is a risk factor for placental dysfunction, suggesting that factors within an obese environment may impair early placental development. Herein, we tested the hypothesis that palmitic acid, a saturated fatty acid circulating at high levels in obese women, induces an inflammatory response in EVTs that hinders their capacity to migrate toward SMCs. We found …

Three types of evidence evaluation were used in this review: systematic reviews, scoping reviews, and evidence updates. Per agreement with the evidence evaluation recommendations of the International Liaison Committee on Resuscitation, only systematic reviews could result in a new or revised treatment recommendation. Systematic reviews performed for this 2020 CoSTR for pediatric life support included the topics of sequencing of airway-breaths-compressions versus compressions-airway-breaths …

Physical Activity Throughout Pregnancy Is Key To Preventing Chronic Disease, Taniya S. Nagpal, Michelle F. Mottola

Paediatrics Publications

According to The Developmental Origins of Health and Disease theory, the intrauterine environment of the developing fetus may impact later life physiology, including susceptibility to chronic disease conditions. Maternal exposures during pregnancy can affect the intrauterine environment and result in fetal programming for chronic diseases through changes in the structure or function of specific organs. Negative maternal exposures, such as poor nutrition intake, have been shown to increase the risk for later life chronic diseases. On the contrary, healthful behaviors, such as physical activity, may have a positive and protective effect against chronic disease risk. This narrative review summarizes literature …

Tp63-Mutation As A Cause Of Prenatal Lethal Multicystic Dysplastic Kidneys, Isabel Friedmann, Carla Campagnolo, Nancy Chan, Ghislain Hardy, Maha Saleh

Paediatrics Publications

BACKGROUND: Ectrodactyly-ectodermal dysplasia-clefting syndrome 3 (EEC) is one of the six overlapping syndromes caused by mutations in the tumor protein p63 gene (TP63). EEC is suspected when patients have cleft hands or feet, polydactyly, and syndactyly, abnormal development of the ectodermally derived structures, and orofacial clefting. Genitourinary (GU) anomalies have been identified in patients with EEC, yet these are often under-recognized and under-reported. The available literature on sonographic prenatal findings is sparse, especially when considering GU anomalies.

METHODS: We present the case of a male stillborn fetus, who was found antenatally to have multicystic dysplastic kidneys and anhydramnios. Following the …

Paediatrics Publications

BACKGROUND: Spinal muscular atrophy (SMA) is a devastating rare disease that affects individuals regardless of ethnicity, gender, and age. The first-approved disease-modifying therapy for SMA, nusinursen, was approved by Health Canada, as well as by American and European regulatory agencies following positive clinical trial outcomes. The trials were conducted in a narrow pediatric population defined by age, severity, and genotype. Broad approval of therapy necessitates close follow-up of potential rare adverse events and effectiveness in the larger real-world population.

METHODS: The Canadian Neuromuscular Disease Registry (CNDR) undertook an iterative multi-stakeholder process to expand the existing SMA dataset to capture items …

Yousif, Michele D. Calder, Jin Tong Du, Kelsey N. Ruetz, Kylie Crocker, Brad L. Urquhart, Dean H. Betts, Basim Abu Rafea, Andrew J. Watson

Paediatrics Publications

Obesity is associated with altered fatty acid profiles, reduced fertility, and assisted reproductive technology (ART) success. The effects of palmitic acid (PA), oleic acid (OA), and their combination on mouse preimplantation development, endoplasmic reticulum (ER) stress pathway gene expression, lipid droplet formation, and mitochondrial reactive oxygen species (ROS) were characterized. Two-cell stage mouse embryos collected from superovulated and mated CD1 females were placed into culture with KSOMaa medium, or PA alone or in combination with OA for 46 h. PA significantly reduced blastocyst development in a concentration-dependent manner, which was prevented by co-treatment with OA. PA and OA levels in …
