BackgroundCurrent fetal-infant growth references have an obvious growth disjuncture around 40 week gestation overlapping where the fetal and infant growth references are combined. Graphical smoothening of the disjuncture to connect the matching percentile curves has never been validated. This study was designed to compare weight gain patterns of contemporary preterm infants with a fetal-infant growth reference (derived from a meta-analysis) to validate the previous smoothening assumptions and inform the revision of the Fenton chart.MethodsGrowth and descriptive data of preterm infants (23 to 31 weeks) from birth through 10 weeks post term age were collected in three cities in Canada and the USA between 2001 and 2010 (n = 977). Preterm infants were grouped by gestational age into 23–25, 26–28, and 29–31 weeks. Comparisons were made between the weight data of the preterm cohort and the fetal-infant growth reference.ResultsMedian weight gain curves of the three preterm gestational age groups were almost identical and remained between the 3rd and the 50th percentiles of the fetal-infant-growth-reference from birth through 10 weeks post term. The growth velocity of the preterm infants decreased in a pattern similar to the decreased velocity of the fetus and term infant estimates, from a high of 17–18 g/kg/day between 31–34 weeks to rates of 4–5 g/kg/day by 50 weeks in each gestational age group. The greatest discrepancy in weight gain velocity between the preterm infants and the fetal estimate was between 37 and 40 weeks; preterm infants grew more rapidly than the fetus. The infants in this study regained their birthweight earlier compared to those in the 1999 National Institute of Child Health and Human Development report.ConclusionThe weight gain velocity of preterm infants through the period of growth data disjuncture between 37 and 50 weeks gestation is consistent with and thus validates the smoothening assumptions made between preterm and post-term growth references.

Child-parent perceptions of HRQOL in a multiethnic population with CD are comparable to healthy reference populations, but significantly higher than in parent/child GI-CON. Adherence to the GFD in ethnically diverse youth with CD was related to GI symptoms, age of the child, and ethnicity of the parent-child.

BackgroundFew studies in recent years have demonstrated the effect of maternal diet on fatty acid composition of human milk.MethodsFourteen free-living lactating women participated in a cross-over dietary intervention study, consuming a low fat diet (17.6% of energy as fat, 14.4% of energy as protein, 68.0% of energy as carbohydrate) and a high fat diet (40.3% of energy as fat, 14.4% of energy as protein, 45.3% of energy as carbohydrate) each for periods of 4 days, in randomised order. Each mother was her own control. Mature milk samples were collected during each period and analysed for medium and long chain fatty acids.ResultsThe concentration of medium chain fatty acids (MCFA), was 13.6% in breast milk for the low fat diet compared to 11.4% for the high fat (p < 0.05). Arachidonic acid (C20:4n-6) levels were significantly higher in breast milk when women consumed the low fat diet. Increased dietary intake of stearic acid (C18:0) and alpha-linolenic acid (C18:3n-3) on the high fat diet significantly increased proportions of these fatty acids in breast milk (p < 0.05) in 4 days.ConclusionsChanging maternal dietary fat intake has a rapid response in terms of changes to fatty acids in breast milk.

The Integrated Nutrition Pathway for Acute Care (INPAC) is an evidence and consensus based pathway developed to guide health care professionals in the prevention, detection, and treatment of malnutrition in medical and surgical patients. From 2015 to 2017, the More-2-Eat implementation project (M2E) used a participatory action research approach to determine the feasibility, and evaluate the implementation of INPAC in 5 hospital units across Canada. Based on the findings of M2E and consensus with M2E stakeholders, updates have been made to INPAC to enhance feasibility in Canadian hospitals. The learnings from M2E have been converted into an online toolkit that outlines how to implement the key steps within INPAC. The aim of this short report is to highlight the updated version of INPAC, and introduce the implementation toolkit that was used to support practice improvements towards this standard.Electronic supplementary materialThe online version of this article (10.1186/s12937-017-0310-1) contains supplementary material, which is available to authorized users.

The findings articulate the KSA, training needs, and barriers to precepting considered significant for dietitian preceptors. The results are important for the advocacy for resources to support the training and development of preceptors, upon whom sustainability of the profession depends.

In-hospital malnutrition and inadequate food intake have been associated with negative outcomes (e.g., prolonged length of stay, readmission, mortality, and increased hospital costs). Studies examining the factors associated with low food intake in hospital, commonly defined as the consumption of ≤50% of meals, have produced mixed results. We examined the correlates of food intake including patient socioeconomic, demographic, and health characteristics, institutional factors, and common clinical strategies in 1129 medical patients from 5 Canadian hospitals. Low food intake was found in 35% of patients (41% of females and 29% of males) (p < 0.001). In multivariate analyses, sex, socioeconomic status, demographics, and diagnoses were not significantly related to food intake. Patients assessed as malnourished (subjective global assessment (SGA) B/C) (odds ratio (OR), 2.41; p = 0.003) or as not at risk of malnutrition (OR, 1.67; p = 0.040) were more likely to have low intake when compared with those assessed as well nourished (SGA A). Patient reports of mealtime challenges (OR, 2.70; p < 0.001) and barriers to food intake (OR, 1.11; p = 0.008) were positively related to low intake throughout the study sample. Higher 12-Item Short Form Health Survey Mental Component Summary scores were related to better food intake (OR, 0.98; p < 0.001). Clinical strategies such as between-meal snacks lowered the likelihood of low food intake (OR, 0.55; p = 0.037), whereas a group of "other strategies" increased the odds (OR, 2.77; p = 0.001). These results offer a better understanding of the correlates of in-hospital low food intake. The conclusion discusses some avenues for improving food intake in the clinical setting, such as better mealtime monitoring and a reduction in barriers to food intake.
