Removing barriers to accessing medical cannabis for paediatric patients

Medical cannabis (MC) may offer therapeutic benefits for children with complex neurological conditions and chronic diseases. In Canada, parents, and caregivers frequently report encountering barriers when accessing MC for their children. These include negative preconceived notions about risks and benefits, challenges connecting with a knowledgeable healthcare provider (HCP), the high cost of MC products, and navigating MC product shortages. In this manuscript, we explore several of these barriers and provide recommendations to decision-makers to enable a family-centered and evidence-based approach to MC medicine and research for children.

Source of human milk (mother or donor) is more important than fortifier type (human or bovine) in shaping the preterm infant microbiome

Milk fortifiers help meet the nutritional needs of preterm infants receiving their mother’s own milk (MOM) or donor human milk. We conducted a randomized clinical trial (NCT03214822) in 30 very low birth weight premature neonates comparing bovine-derived human milk fortifier (BHMF) versus human-derived fortifier (H2MF). We found that fortifier type does not affect the overall microbiome, although H2MF infants were less often colonized by an unclassified member of Clostridiales Family XI. Secondary analyses show that MOM intake is strongly associated with weight gain and microbiota composition, including Bifidobacterium, Veillonella, and Propionibacterium enrichment. Finally, we show that while oxidative stress (urinary F2-isoprostanes) is not affected by fortifier type or MOM intake, fecal calprotectin is higher in H2MF infants and lower in those consuming more MOM. Overall, the source of human milk (mother versus donor) appears more important than the type of milk fortifier (human versus bovine) in shaping preterm infant gut microbiota.

•

Milk fortifier type (human versus bovine) has little impact on the preterm microbiome

•

Milk source (mother versus donor) is strongly associated with microbiome composition

•

Feeding mother’s own milk is linked to better weight gain and less gut inflammation

L’assurance médicaments au Canada : le point de vue de la pédiatrie

Le système d’assurance médicaments du Canada est l’un des plus coûteux au monde, mais des millions de Canadiens peinent pourtant à accéder aux médicaments dont ils ont besoin. C’est pourquoi les gouvernements fédéral, provinciaux et territoriaux envisagent des propositions de polices d’assurance médicaments publiques pour tous les Canadiens. Les polices d’assurance médicaments permettent de prioriser les enfants et les adolescents, dont les besoins pharmacologiques particuliers ont longtemps été négligés. La prise de médicaments sur ordonnance est courante au sein de cette population, puisqu’environ la moitié des enfants et des adolescents canadiens ont besoin d’au moins une ordonnance au cours d’une année donnée. La prise de médicaments demeure toutefois concentrée au sein des populations atteintes de maladies complexes, chroniques ou graves. Les enfants et les adolescents recourent largement aux préparations magistrales et aux médicaments dans un emploi non conforme à l’étiquette, ce qui a une incidence sur l’innocuité, l’efficacité, la palatabilité et les coûts. Les organes décisionnels en matière de remboursement n’accordent pas toute l’importance qu’ils devraient aux avantages uniques des médicaments pédiatriques, ce qui inclut les formulations adaptées à la pédiatrie, une meilleure qualité de vie pour les enfants et les familles et les économies à l’extérieur du système de santé. Quel que soit le modèle d’assurance médicaments finalement adopté, il est essentiel d’offrir une couverture d’assurance médicaments sur ordonnance complète, universelle et transférable pour tous les enfants et les adolescents. C’est pourquoi les experts des médicaments pédiatriques doivent créer un formulaire national de médicaments pédiatriques fondé sur des données probantes. Santé Canada doit également améliorer les processus pour que les formulations et médicaments commerciaux adaptés à la pédiatrie deviennent plus disponibles et accessibles. À cette fin, le gouvernement fédéral doit également soutenir la recherche-développement des médicaments pédiatriques.

A clinical tool for reducing central nervous system depression among neonates exposed to codeine through breast milk

Background

Neonates are commonly exposed to maternal codeine through breast milk. Central Nervous System (CNS) depression has been reported in up to 24% of nurslings following codeine exposure. In 2009, we developed guidelines to improve the safety of codeine use during breastfeeding based on previously established pharmacogenetic and clinical risk factors. The primary objective of this study was to prospectively evaluate the effectiveness of these guidelines in ensuring neonatal safety.

Methods and Findings

Women taking codeine for pain following caesarean section were given safety guidelines, including advice to use the lowest codeine dose for no longer than four days and to switch to a non-opioid when possible. Mothers provided a saliva sample for analysis of genes involved in opioid disposition, metabolism and response. A total of 238 consenting women participated. Neonatal sedation was reported in 2.1% (5/238) of breastfeeding women taking codeine according to our safety guidelines. This rate was eight fold lower than that reported in previous prospective studies. Women reporting sedated infants were taking codeine for a significantly longer period of time (4.80±2.59 days vs. 2.52±1.58 days, p = 0.0018). While following the codeine safety guidelines, mothers were less likely to supplement with formula, reported lower rates of sedation in themselves and breastfed more frequently throughout the day when compared to previously reported rates. Genotyping analysis of cytochrome p450 2D6 (CYP2D6), uridine-diphosphate glucuronosyltransferase (UGT) 2B7, p-glycoprotein (ABCB1), the mu-opioid receptor (OPRM1) and catechol-o-demethyltransferase (COMT) did not predict codeine response in breastfeeding mother/infant pairs when following the safety guidelines.

Conclusions

The only cases of CNS depression occurred when the length of codeine use exceeded the guideline recommendations. Neonatal safety of codeine can be improved using evidence-based guidelines, even in those deemed by genetics to be at high risk for toxicity.
