2.  Accidental exposures to peanut in a large cohort of Canadian children with peanut allergy 
Background
We previously estimated that the annual rate of accidental exposure to peanut in 1411 children with peanut allergy, followed for 2227 patient-years, was 11.9% (95% CI, 10.6, 13.5). This cohort has increased to 1941 children, contributing 4589 patient-years, and we determined the annual incidence of accidental exposure, described the severity, management, location, and identified associated factors.
Findings
Children with physician-confirmed peanut allergy were recruited from Canadian allergy clinics and allergy advocacy organizations from 2004 to May 2014. Parents completed questionnaires regarding accidental exposure to peanut over the preceding year. Five hundred and sixty-seven accidental exposures occurred in 429 children over 4589 patient-years, yielding an annual incidence rate of 12.4% (95% CI, 11.4, 13.4). Of 377 accidental exposures that were moderate or severe, only 109 (28.9%) sought medical attention and of these 109, only 40 (36.7%) received epinephrine. Of the 181 moderate/severe accidental exposures treated outside a health care facility, only 11.6% received epinephrine. Thirty-seven percent of accidental exposures occurred at home. In multivariate analyses, longer disease duration, recruitment through an allergy advocacy association, and having other food allergies decreased the likelihood of accidental exposures. Age ≥ 13 years at study entry and living with a single parent increased the risk.
Conclusion
Despite increased awareness, accidental exposures continue to occur, mainly at home, and most are managed inappropriately by both health care professionals and caregivers. Consequently, more education is required on the importance of strict allergen avoidance and the need for prompt and correct management of anaphylaxis.

3.  CSACI position statement: systemic effect of inhaled corticosteroids on adrenal suppression in the management of pediatric asthma 
Asthma is a chronic inflammatory disease of the airways that affects a growing number of children and adolescents. Inhaled corticosteroids (ICS) are the mainstay of treatment in persistent asthma, with a stepwise approach to increasing doses of ICS depending on asthma severity and control. ICS have known local and systemic side effects, of which adrenal suppression is still under-recognized. The latter is associated with chronic exposure and higher doses, although it has rarely been reported in children receiving low doses for a short period of time. The Canadian Society of Allergy and Clinical Immunology (CSACI) therefore recommends that physicians screen for adrenal suppression in children receiving high doses for more than 6 months and to consider screening those on medium dose if the risk is deemed higher by factors that increase an individual’s systemic corticosteroid exposure. Morning serum cortisol level can be used as a screening tool and abnormal results or normal results with a high index of suspicion should be confirmed with low-dose ACTH stimulation tests.

5.  Dietary exposures and allergy prevention in high-risk infants 
Paediatrics & Child Health  2013;18(10):545-549.
Allergic conditions in children are a prevalent health concern in Canada. The burden of disease and the societal costs of proper diagnosis and management are considerable, making the primary prevention of allergic conditions a desirable health care objective. This position statement reviews current evidence on dietary exposures and allergy prevention in infants at high risk for developing allergic conditions. It revisits previous dietary recommendations for pregnancy, breastfeeding and formula feeding, and provides an approach for introducing solid foods to high-risk infants. While there is no evidence that delaying the introduction of any specific food beyond six months of age helps to prevent allergy, the protective effect of early introduction of potentially allergenic foods (at four to six months of age) remains under investigation. Recent research appears to suggest that regularly ingesting a new, potentially allergenic food may be as important as when that food is first introduced.

7.  IgE-Mediated allergy to wheat in a child with celiac disease – a case report 
Introduction
Celiac disease and immediate type hypersensitivity to wheat are immune responses with different pathogenic mechanisms. Both diseases are well known entities but their coexistence in the same patient is rarely reported. This is a unique case presentation of a patient with celiac disease who developed concomitant IgE-mediated wheat allergy and presented with immediate symptoms in two body systems.
Case presentation
We report the case of a girl with celiac disease who subsequently developed IgE-mediated hypersensitivity to wheat. The patient is a Caucasian female who was diagnosed with celiac disease at 18 months of age after presenting with recurrent vomiting and failure to thrive. Her anti-tTG antibody level was greater than 200 E.U. and biopsy results from endoscopy were consistent with celiac disease. Specific IgE antibody to wheat was negative at 2 years of age. Around seven years of age, she developed immediate symptoms of urticaria, cough and shortness of breath with accidental exposures to wheat. Specific IgE antibody testing was repeated and positive to wheat (42.5 kU/L), as well as rye (33.9 kU/L), barley (53.4 kU/L) and oat (11.3 kU/L). At 9 years of age, skin prick testing was positive to wheat, barley and rye but negative to oat. The patient has subsequently tolerated an open oral food challenge to oat. She continues to avoid wheat, rye and barley and carries an epinephrine autoinjector at all times.
Conclusion
To our knowledge, this is the first report of a patient with celiac disease and concomitant IgE-mediated allergy to wheat presenting with immediate symptoms in two body systems. Although the pathophysiology of these diseases is different, this case demonstrates that they are not exclusive of one another. In patients who develop unexplained symptoms consistent with IgE-mediated allergy, an allergy assessment should be considered.

8.  Inhibition of KRAS-driven tumorigenicity by interruption of an autocrine cytokine circuit 
Cancer discovery  2014;4(4):452-465.
Although the roles of mitogen-activated protein kinase (MAPK) and phosphatidylinositol-3 kinase (PI3K) signaling in KRAS-driven tumorigenesis are well established, KRAS activates additional pathways required for tumor maintenance, inhibition of which are likely to be necessary for effective KRAS-directed therapy. Here we show that the IKK-related kinases TBK1 and IKKε promote KRAS-driven tumorigenesis by regulating autocrine CCL5 and IL-6 and identify CYT387 as a potent JAK/TBK1/IKKε inhibitor. CYT387 treatment ablates RAS-associated cytokine signaling and impairs Kras-driven murine lung cancer growth. Combined CYT387 and MEK inhibitor therapy induces regression of aggressive murine lung adenocarcinomas driven by Kras mutation and p53 loss. These observations reveal that TBK1/IKKε promote tumor survival by activating CCL5 and IL-6 and identify concurrent inhibition of TBK1/IKKε, JAK, and MEK signaling as an effective approach to inhibit the actions of oncogenic KRAS.

10.  The roles of sphingosine kinase 1 and 2 in regulating the Warburg effect in prostate cancer cells 
Cellular signalling  2013;25(4):1011-1017.
SUMMARY
Two isoforms of sphingosine kinase, SK1 and SK2, catalyze the formation of the bioactive lipid sphingosine 1-phosphate (S1P) in mammalian cells. We have previously shown that treatment of androgen-sensitive LNCaP prostate cancer cells with a non-selective SK isoform inhibitor, 2-(p-hydroxyanilino)- 4-(p-chlorophenyl)thiazole (SKi), induces the proteasomal degradation of SK1. This is concomitant with a significant increase in C22:0-ceramide and sphingosine levels and a reduction in S1P levels, resulting in the apoptosis of LNCaP cells. In contrast, we show here that a SK2-selective inhibitor, (R)-FTY720 methyl ether (ROME), increases sphingosine and decreases S1P levels but has no effect on ceramide levels and does not induce apoptosis in LNCaP cells. We also show that several glycolytic metabolites and (R)-S-lactoylglutathione are increased upon treatment of LNCaP cells with SKi, which induces the proteasomal degradation of c-Myc. These changes reflect an indirect antagonism of the Warburg effect. LNCaP cells also respond to SKi by diverting glucose 6-phosphate into the pentose phosphate pathway to provide NADPH, which serves as an antioxidant to counter an oxidative stress response. SKi also promotes the formation of a novel pro-apoptotic molecule called diadenosine 5′,5‴-P1,P3-triphosphate (Ap3A), which binds to the tumor suppressor fragile histidine triad protein (FHIT). In contrast, the SK2-selective inhibitor, ROME, induces a reduction in some glycolytic metabolites and does not affect oxidative stress. We conclude that SK1 functions to increase the stability of c-Myc and suppresses Ap3A formation, which might maintain the Warburg effect and cell survival, while SK2 exhibits a non-overlapping function.

11.  Early exposure to food and food allergy in children 
Canadian Family Physician  2014;60(4):338-339.
Abstract
Question I have been under the impression that infants should avoid potential allergenic foods such as nuts, cow’s milk, and eggs in order to avoid developing allergic reactions. What advice should I give parents regarding the introduction of food in infancy and the development of food allergy?
Answer There is no evidence that delaying the introduction of any specific food beyond 6 months of age helps to prevent allergy. A recent Canadian Paediatric Society statement recommends no delay in the introduction of food in infancy. Recent research also appears to suggest that early introduction of potentially allergenic foods (at 4 to 6 months of age) might actually provide a form of protection and help prevent allergy, but more research is needed.

12.  Exposition précoce aux aliments et allergies alimentaires chez les enfants 
Canadian Family Physician  2014;60(4):e208-e210.
Résumé
Question J’étais sous l’impression qu’on devrait éviter de donner aux nourrissons des aliments potentiellement allergènes comme des noix, du lait de vache et des œufs pour prévenir le développement de réactions allergiques. Quels conseils devrait-on donner aux parents concernant l’introduction des aliments durant la petite enfance et le développement des allergies alimentaires?
Réponse Il n’y a pas de données probantes indiquant que retarder l’introduction d’aliments particuliers après l’âge de 6 mois aide à prévenir les allergies. Une récente déclaration de la Société canadienne de pédiatrie ne recommande aucun délai quant à l’introduction d’aliments durant la petite enfance. De récentes études de recherche semblent aussi faire valoir que l’introduction précoce (entre 4 et 6 mois) d’aliments possiblement allergènes procure une forme de protection et contribue à prévenir les allergies, mais il faudrait plus de recherche à ce sujet.

13.  Structure and ubiquitination-dependent activation of Tank-Binding Kinase 1 
Cell reports  2013;3(3):10.1016/j.celrep.2013.01.033.
Summary
Upon stimulation by pathogen-associated inflammatory signals, the atypical IκB kinase TBK1 induces type-I interferon expression and modulates NF-κB signaling. Here we describe the 2.4 Å-resolution crystal structure of nearly full-length TBK1 in complex with specific inhibitors. The structure reveals a novel dimeric assembly, created by an extensive network of interactions among the kinase, ubiquitin-like (ULD) and scaffold/dimerization (SDD) domains. An intact TBK1 dimer undergoes K63-linked polyubiquitination on Lysine 30 and Lysine 401, and these modifications are required for TBK1 activity. The ubiquitination sites and dimer contacts are conserved in the close homolog IKKε, but not in the canonical IκB kinase IKKβ, which assembles in an unrelated manner. The multidomain architecture of TBK1 provides a structural platform for integrating ubiquitination with kinase activation and IRF3 phosphorylation. The structure of TBK1 will facilitate studies of the atypical IκB kinases in normal and disease physiology and will further development of more specific inhibitors that may be useful as anti-cancer or anti-inflammatory agents.

15.  Regulation of nutrient-sensitive autophagy by uncoordinated 51-like kinases 1 and 2 
Autophagy  2013;9(3):361-373.
Macroautophagy, commonly referred to as autophagy, is a protein degradation pathway that occurs constitutively in cells, but can also be induced by stressors such as nutrient starvation or protein aggregation. Autophagy has been implicated in multiple disease mechanisms including neurodegeneration and cancer, with both tumor suppressive and oncogenic roles. Uncoordinated 51-like kinase 1 (ULK1) is a critical autophagy protein near the apex of the hierarchal regulatory pathway that receives signals from the master nutrient sensors MTOR and AMP-activated protein kinase (AMPK). In mammals, ULK1 has a close homolog, ULK2, although their functional distinctions have been unclear. Here, we show that ULK1 and ULK2 both function to support autophagy activation following nutrient starvation. Increased autophagy following amino acid or glucose starvation was disrupted only upon combined loss of ULK1 and ULK2 in mouse embryonic fibroblasts. Generation of PtdIns3P and recruitment of WIPI2 or ZFYVE1/DFCP1 to the phagophore following amino acid starvation was blocked by combined Ulk1/2 double knockout. Autophagy activation following glucose starvation did not involve recruitment of either WIPI1 or WIPI2 to forming autophagosomes. Consistent with a PtdIns3P-independent mechanism, glucose-dependent autophagy was resistant to wortmannin. Our findings support functional redundancy between ULK1 and ULK2 for nutrient-dependent activation of autophagy and furthermore highlight the differential pathways that respond to amino acid and glucose deprivation.

16.  The sphingosine kinase inhibitor 2-(p-hyroxyanilino)-4-(p-chlorophenyl) thiazole reduces androgen receptor expression via an oxidative stress-dependent mechanism 
British Journal of Pharmacology  2013;168(6):1497-1505.
Background and Purpose
Sphingosine kinase catalyses the formation of sphingosine 1-phosphate and is linked with androgen receptor signalling in prostate cancer cells. Therefore, we investigated the effect of sphingosine kinase inhibitors on androgen receptor expression.
Experimental Approach
Androgen-sensitive LNCaP cells were treated with SKi (2-(p-hydroxyanilino)-4-(p-chlorophenyl)thiazole), which inhibits sphingosine kinases 1 and 2 activity, and the effect on androgen receptor expression was measured.
Key Results
Treatment of cells with SK1 inhibitors reduced the expression of the androgen receptor and prostate-specific antigen, while (R)-FTY720 methyl ether (a sphingosine-kinase-2-selective inhibitor), at a concentration that eliminates sphingosine kinase 2 from cells, had no significant effect on androgen receptor expression. The effect of SKi on androgen receptor expression was independent of the SKi-induced proteasomal degradation of SK1 and was post translational, although androgen receptor mRNA transcript was reduced. Fumonisin B1 (a ceramide synthase inhibitor) also failed to reverse the effect of SKi on androgen receptor expression, thereby excluding a role for ceramide derived from the salvage pathway. The effect of SKi on androgen receptor expression was reversed by N-acetylcysteine, which was used to scavenge reactive oxygen species.
Conclusion and Implications
Inhibition of sphingosine kinase 1 activity abrogates androgen receptor signalling via an oxidative stress-induced, p53-independent mechanism in prostate cancer cells. Therefore, SK1 inhibitors may offer therapeutic potential in promoting the removal of AR receptors from prostate cancer cells, resulting in an increased efficacy, which is likely to be superior to inhibitors that simply reversibly inhibit AR signalling.

Autophagy  2012;8(4):445-544.
In 2008 we published the first set of guidelines for standardizing research in autophagy. Since then, research on this topic has continued to accelerate, and many new scientists have entered the field. Our knowledge base and relevant new technologies have also been expanding. Accordingly, it is important to update these guidelines for monitoring autophagy in different organisms. Various reviews have described the range of assays that have been used for this purpose. Nevertheless, there continues to be confusion regarding acceptable methods to measure autophagy, especially in multicellular eukaryotes. A key point that needs to be emphasized is that there is a difference between measurements that monitor the numbers or volume of autophagic elements (e.g., autophagosomes or autolysosomes) at any stage of the autophagic process vs. those that measure flux through the autophagy pathway (i.e., the complete process); thus, a block in macroautophagy that results in autophagosome accumulation needs to be differentiated from stimuli that result in increased autophagic activity, defined as increased autophagy induction coupled with increased delivery to, and degradation within, lysosomes (in most higher eukaryotes and some protists such as Dictyostelium) or the vacuole (in plants and fungi). In other words, it is especially important that investigators new to the field understand that the appearance of more autophagosomes does not necessarily equate with more autophagy. In fact, in many cases, autophagosomes accumulate because of a block in trafficking to lysosomes without a concomitant change in autophagosome biogenesis, whereas an increase in autolysosomes may reflect a reduction in degradative activity. Here, we present a set of guidelines for the selection and interpretation of methods for use by investigators who aim to examine macroautophagy and related processes, as well as for reviewers who need to provide realistic and reasonable critiques of papers that are focused on these processes. These guidelines are not meant to be a formulaic set of rules, because the appropriate assays depend in part on the question being asked and the system being used. In addition, we emphasize that no individual assay is guaranteed to be the most appropriate one in every situation, and we strongly recommend the use of multiple assays to monitor autophagy. In these guidelines, we consider these various methods of assessing autophagy and what information can, or cannot, be obtained from them. Finally, by discussing the merits and limits of particular autophagy assays, we hope to encourage technical innovation in the field.

21.  What are the beliefs of pediatricians and dietitians regarding complementary food introduction to prevent allergy? 
Background
The timing of complementary food introduction is controversial. Providing information on the timing of dietary introduction is crucial to the primary prevention of food allergy. The American Academy of Pediatrics offers dietary recommendations that were updated in 2008.
Objective
Identify the recommendations that general pediatricians and registered dietitians provide to parents and delineate any differences in counselling.
Methods
A 9-item survey was distributed to pediatricians and dietitians online and by mail. Information on practitioner type, gender, length of practice and specific recommendations regarding complementary food introduction and exposure was collected.
Results
181 surveys were returned with a 54% response rate from pediatricians. It was not possible to calculate a meaningful dietitian response rate due to overlapping email databases. 52.5% of all respondents were pediatricians and 45.9% were dietitians. The majority of pediatricians and dietitians advise mothers that peanut abstinence during pregnancy and lactation is unnecessary. Dietitians were more likely to counsel mothers to breastfeed their infants to prevent development of atopic dermatitis than pediatricians. Hydrolyzed formulas for infants at risk of developing allergy were the top choice of formula amongst both practitioners. For food allergy prevention, pediatricians were more likely to recommend delayed introduction of peanut and egg, while most dietitians recommended no delay in allergenic food introduction.
Conclusions
In the prophylaxis of food allergy, pediatricians are less aware than dietitians of the current recommendation that there is no benefit in delaying allergenic food introduction beyond 4 to 6 months. More dietitians than pediatricians believe that breastfeeding decreases the risk of atopic dermatitis. Practitioners may benefit from increased awareness of current guidelines.

22.  Huntingtin and Huntingtin-Associated Protein 1 Influence Neuronal Calcium Signaling Mediated by Inositol-(1,4,5) Triphosphate Receptor Type 1 
Neuron  2003;39(2):227-239.
Summary
Huntington’s disease (HD) is caused by polyglutamine expansion (exp) in huntingtin (Htt). The type 1 inositol (1,4,5)-triphosphate receptor (InsP3R1) is an intracellular calcium (Ca2+) release channel that plays an important role in neuronal function. In a yeast two-hybrid screen with the InsP3R1 carboxy terminus, we isolated Htt-associated protein-1A (HAP1A). We show that an InsP3R1-HAP1A-Htt ternary complex is formed in vitro and in vivo. In planar lipid bilayer reconstitution experiments, InsP3R1 activation by InsP3 is sensitized by Httexp, but not by normal Htt. Transfection of full-length Httexp or caspase-resistant Httexp, but not normal Htt, into medium spiny striatal neurons faciliates Ca2+ release in response to threshold concentrations of the selective mGluR1/5 agonist 3,5-DHPG. Our findings identify a novel molecular link between Htt and InsP3R1-mediated neuronal Ca2+ signaling and provide an explanation for the derangement of cytosolic Ca2+ signaling in HD patients and mouse models.
