Treatment With Aicar Inhibits Blastocyst Development, Trophectodermdifferentiation And Tight Junction Formation And Function In Mice, Michele D. Calder, Nicole A. Edwards, Dean H. Betts, Andrew J. Watson

Paediatrics Publications

STUDY QUESTION: What is the impact of adenosine monophosphate-activated protein kinase (AMPK) activation on blastocyst formation, gene expression, and tight junction formation and function? SUMMARY ANSWER: AMPK activity must be tightly controlled for normal preimplantation development and blastocyst formation to occur. WHAT IS KNOWN ALREADY: AMPK isoforms are detectable in oocytes, cumulus cells and preimplantation embryos. Cultured embryos are subject to many stresses that can activate AMPK. STUDY DESIGN, SIZE, DURATION: Two primary experiments were carried out to determine the effect of AICAR treatment on embryo development and maintenance of the blastocoel cavity. Embryos were recovered from superovulated mice. First, …

The Role Of Adverse Childhood Experiences As Determinants Of Non-Suicidal Self-Injury Among Children And Adolescents Referred To Community And Inpatient Mental Health Settings, Philip Baiden, Shannon L. Stewart, Barbara Fallon

Paediatrics Publications

The objectives of this study were to examine the prevalence of, and determine the effect of adverse childhood experiences on non-suicidal self-injury among children and adolescents referred to community and inpatient mental health settings. Data for this study were obtained from the interRAI Child and Youth Mental Health dataset. A total of 2038 children and adolescents aged 8–18 years (M = 12.49; SD = 2.88, 61.1% males) were analyzed. Binary logistic regression was fitted to identify predictors of non-suicidal self-injury as a function of adverse childhood experiences, depression, and social support while simultaneously controlling for age, gender, type of patient, …

Intranasal Ketamine For Procedural Sedation And Analgesia In Children: A Systematic Review, Naveen Poonai, Kyle Canton, Samina Ali, Shawn Hendrikx, Amit Shah, Michael Miller, Gary Joubert, Michael Rieder, Lisa Hartling

Paediatrics Publications

Background Ketamine is commonly used for procedural sedation and analgesia (PSA) in children. Evidence suggests it can be administered intranasally (IN). We sought to review the evidence for IN ketamine for PSA in children. Methods We performed a systematic review of randomized trials of IN ketamine in PSA that reported any sedation-related outcome in children 0 to 19 years. Trials were identified through electronic searches of MEDLINE (1946±2016), EMBASE (1947±2016), Google Scholar (2016), CINAHL (1981±2016), The Cochrane Library (2016), Web of Science (2016), Scopus (2016), clinical trial registries, and conference proceedings (2000±2016) without language restrictions. The methodological qualities of studies …

Guideline For The Prevention Of Oral And Oropharyngeal Mucositis In Children Receiving Treatment For Cancer Or Undergoing Haematopoietic Stem Cell Transplantation, Lillian Sung, Paula Robinson, Nathaniel Treister, Tina Baggott, Paul Gibson, Wim Tissing, John Wiernikowski, Jennifer Brinklow, L Lee Dupuis

Paediatrics Publications

PURPOSE: To develop an evidence-based clinical practice guideline for the prevention of oral mucositis in children (0-18 years) receiving treatment for cancer or undergoing haematopoietic stem cell transplantation (HSCT).

METHODS: The Mucositis Prevention Guideline Development Group was interdisciplinary and included internationally recognised experts in paediatric mucositis. For the evidence review, we included randomised controlled trials (RCTs) conducted in either children or adults evaluating the following interventions selected according to prespecified criteria: cryotherapy, low level light therapy (LLLT) and keratinocyte growth factor (KGF). We also examined RCTs of any intervention conducted in children. For all systematic reviews, we synthesised the occurrence …

Pu.1 Regulates Ig Light Chain Transcription And Rearrangement In Pre-B Cells During B Cell Development, Carolina R. Batista, Stephen K.H. Li, Li S. Xu, Lauren A. Solomon, Rodney P. Dekoter

Paediatrics Publications

B cell development and Ig rearrangement are governed by cell type- and developmental stage-specific transcription factors. PU.1 and Spi-B are E26-transformation-specific transcription factors that are critical for B cell differentiation. To determine whether PU.1 and Spi-B are required for B cell development in the bone marrow, Spi1 (encoding PU.1) was conditionally deleted in B cells by Cre recombinase under control of the Mb1 gene in Spib (encoding Spi-B)-deficient mice. Combined deletion of Spi1 and Spib resulted in a lack of mature B cells in the spleen and a block in B cell development in the bone marrow at the small …

How Does The Social “Get Under The Gums”? The Role Of Socio-Economic Position In The Oral-Systemic Health Link, Noha Gomaa, Belinda Nicolau, Arjumand Siddiqi, Howard Tenenbaum, Michael Glogauer, Carlos Quiñonez

Paediatrics Publications

OBJECTIVES: To evaluate the extent of association between systemic inflammation and periodontal disease in American adults, and to assess whether socio-economic position mediated this relationship. METHODS: We used data from the National Health and Nutrition Examination Survey (NHANES IV) (2001-2010). Systemic inflammation was defined by individual and aggregate (cumulative inflammatory load) biomarkers (C-reactive protein, white blood cell counts, neutrophil counts, and neutrophil: lymphocyte ratio). Loss of attachment and bleeding on probing were used to define periodontal disease. Poverty:income ratio and education were indicators of socio-economic position. Covariates included age, sex, ethnicity, smoking, alcohol, and attendance for dental treatment. Univariate and …
