Abstract
Women with a history of gestational diabetes (GDM) have difficulty maintaining a healthy diet after delivery. The theory of planned behavior (TPB) is effective in identifying the determinants of adopting a healthy diet. The objectives were to identify the determinants of the intention to adopt a healthy diet among the TPB constructs in women with (GDM+) and without (GDM-) a history of GDM, and to identify the beliefs associated with these constructs. The study was conducted in Québec (Canada) between 2009 and 2017. Data from 213 GDM+ and 91 GDM- women were analyzed. Women completed a questionnaire on the determinants of intention to adopt a healthy diet, defined as adherence to 2007 Canada's Food Guide. The subjective norm and perceived behavioral control (PBC) constructs were associated with the intention to adopt a healthy diet among GDM+ women (β = 2.21 and β = 4.37, respectively, p < 0.0001), whereas among GDM- women, PBC was the only construct associated with intention (β = 0.78; p < 0.0001). More specifically among GDM+ women, the disapproval of a family member other than the partner (β = 1.49; p = 0.0005), not feeling capable of adopting a healthy diet with access to food treats (β = 1.58; p < 0.0001), lack of free time (β = 1.31; p = 0.002), lack of information about healthy eating (β = 1.02; p = 0.015) or lack of easy recipes to prepare (β = 0.84; p = 0.042) was associated with a lower intention to adopt a healthy diet. Overall, among GDM+ women, different beliefs related to the subjective norm and PBC could be targeted to improve the eating habits of this specific population.

Abstract
The gut microbiota and the endocannabinoidome (eCBome) play important roles in regulating energy homeostasis, and both are closely linked to dietary habits. However, the complex and compositional nature of these variables has limited our understanding of their interrelationship. This study aims to decipher the interrelation between dietary intake and the gut microbiome-eCBome axis using two different approaches for measuring dietary intake: one based on whole food and the other on macronutrient intakes. We reveal that food patterns, rather than macronutrient intakes, were associated with the gut microbiome-eCBome axis in a sample of healthy men and women (n = 195). N-acyl-ethanolamines (NAEs) and gut microbial families were correlated with intakes of vegetables, refined grains, olive oil and meats independently of adiposity and energy intakes. Specifically, higher intakes in vegetables and olive oil were associated with increased relative abundance of Clostridiaceae, Veillonellaceae and Peptostreptococaceae, decreased relative abundance of Acidominococaceae, higher circulating levels of NAEs, and higher HDL and LDL cholesterol levels. Our findings highlight the relative importance of food patterns in determining the gut microbiome-eCBome axis. They emphasize the importance of recognizing the contribution of dietary habits in these systems to develop personalized dietary interventions for preventing and treating metabolic disorders through this axis.

Abstract
BACKGROUND Bioactive lipids produced by human cells or by the gut microbiota might play an important role in health and disease. Dietary intakes are key determinants of the gut microbiota, its production of short-chain (SCFAs) and branched-chain fatty acids (BCFAs), and of the host endocannabinoidome signalling, which are all involved in metabolic diseases. This hypothesis-driven longitudinal fixed sequence nutritional study, realized in healthy participants, was designed to determine if a lead-in diet affects the host response to a short-term dietary intervention. Participants received a Mediterranean diet (MedDiet) for 3 days, a 13-day lead-in controlled diet reflecting the average Canadian dietary intake (CanDiet), and once again a MedDiet for 3 consecutive days. Fecal and blood samples were collected at the end of each dietary phase to evaluate alterations in gut microbiota composition and plasma levels of endocannabinoidome mediators, SCFAs, and BCFAs. RESULTS We observed an immediate and reversible modulation of plasma endocannabinoidome mediators, BCFAs, and some SCFAs in response to both diets. BCFAs were more strongly reduced by the MedDiet when the latter was preceded by the lead-in CanDiet. The gut microbiota response was also immediate, but not all changes due to the CanDiet were reversible following a short dietary MedDiet intervention. Higher initial microbiome diversity was associated with reduced microbiota modulation after short-term dietary interventions. We also observed that BCFAs and 2-monoacylglycerols had many, but distinct, correlations with gut microbiota composition. Several taxa modulated by dietary intervention were previously associated to metabolic disorders, warranting the need to control for recent diet in observational association studies. CONCLUSIONS Our results indicate that lipid mediators involved in the communication between the gut microbiota and host metabolism exhibit a rapid response to dietary changes, which is also the case for some, but not all, microbiome taxa. The lead-in diet influenced the gut microbiome and BCFA, but not the endocannabinoidome, response to the MedDiet. A higher initial microbiome diversity favored the stability of the gut microbiota in response to dietary changes. This study highlights the importance of considering the previous diet in studies relating the gut microbiome with lipid signals involved in host metabolism. Video Abstract.

Abstract
Background: Gestational diabetes mellitus (GDM) is known to affect human milk composition. Aims of this study were to compare macronutrient and energy content of human milk of women with (GDM+) and without GDM (GDM-), to assess the association between maternal health and human milk macronutrient and energy content and association between human milk macronutrient and energy content and infant growth. Study Design and Methods: Two months after delivery, hindmilk samples were collected. Triglyceride (TG), lactose, and protein content of human milk were measured. An oral glucose tolerance test was performed. Infant weight and length at birth and 2 months were collected. Weight-for-age (WAZ) and weight-for-length z-scores were calculated. Results: Twenty-four GDM+ and 29 GDM- women were included. Protein, lactose, and energy content of human milk were similar between groups. TG concentration was higher in GDM+ than in GDM- women (6.3 ± 2.0 versus 5.3 ± 1.2, p = 0.04). This difference was no longer significant after adjustment for maternal age and infant sex (p = 0.23). Maternal age was associated with TG (r = 0.28, p = 0.04) and lactose (r = -0.30, p = 0.03), while fasting glucose was associated with proteins (r = 0.30, p = 0.03) and tended to be associated with TG (r = 0.27, p = 0.05) and energy (r = 0.24, p = 0.08). TG levels in human milk were associated with weight (β: 0.26, 95% confidence interval [CI]: 0.02 to 0.50) and WAZ (β: 0.40, 95% CI: 0.05 to 0.75) at 2 months among children unexposed (GDM-) to GDM, but not among children exposed (GDM+) Conclusions: In conclusion, GDM status, maternal age, and fasting glucose level were associated with human milk composition. Finally, TG in human milk was associated with infant growth among GDM- children but not among GDM+ children. ClinicalTrials.gov NCT02872402.

Abstract
The extended endocannabinoid system, also termed endocannabinoidome, participates in multiple metabolic functions in health and disease. Physical activity can both have an acute and chronic impact on endocannabinoid mediators, as does diet. In this crossover randomized controlled study, we investigated the influence of diet on the peripheral response to acute maximal aerobic exercise in a sample of active adult women (n = 7) with no underlying metabolic conditions. We compared the impact of 7-day standardized Mediterranean diet (MedDiet) and control diet inspired by Canadian macronutrient intake (CanDiet) on endocannabinoidome and short-chain fatty acid metabolites post maximal aerobic exercise. Overall, plasmatic endocannabinoids, their congeners and some polyunsaturated fatty acids increased significantly post maximal aerobic exercise upon cessation of exercise and recovered their initial values within 1 h after exercise. Most N-acylethanolamines and polyunsaturated fatty acids increased directly after exercise when the participants had consumed the MedDiet, but not when they had consumed the CanDiet. This impact was different for monoacylglycerol endocannabinoid congeners, which in most cases reacted similarly to acute exercise while on the MedDiet or the CanDiet. Fecal microbiota was only minimally affected by the diet in this cohort. This study demonstrates that endocannabinoidome mediators respond to acute maximal aerobic exercise in a way that is dependent on the diet consumed in the week prior to exercise.

Abstract
OBJECTIVES To evaluate the association between individual and environmental determinants of diet quality with diet quality of children exposed to gestational diabetes mellitus (GDM+) and unexposed (GDM-); to study the association between mother and child vegetables and fruit (VF) intakes. DESIGN Cross-sectional study. PARTICIPANTS One hundred forty-two children (104 GDM+; 38 GDM-) aged 6.2 ± 2.5 years. VARIABLES Canadian Healthy Eating Index 2007 (HEI-C) and VF were obtained with 2 24-hour dietary recall questionnaires in children. Maternal VF was obtained by a validated food frequency questionnaire, and weight and height were measured. Sociodemographic determinants were obtained by questionnaires. ANALYSIS Linear regression models were used to evaluate the association between individual and environmental determinants and the HEI-C score with interaction for GDM status. RESULTS Family meals were associated with HEI-C among GDM- but not GDM+ children (β = 9.97, P = 0.01 and β = -0.41, P = 0.84, respectively; P for interaction = 0.02). Children's age (β = -1.45; 95% confidence interval, -2.19 to -0.72; P < 0.001) was a determinant of HEI-C among all children. Maternal VF intakes were positively associated with children's VF intake (r = 0.30, P < 0.001, r2 = 0.09), with association of larger variance among GDM- children (r = 0.38, r2 = 0.14, P = 0.02) than GDM+ children (r = 0.23, r2 = 0.05, P = 0.02). CONCLUSIONS The food environment at home was associated differently with the diet quality of GDM+ and GDM- children. Whether targeting family meals and maternal diet quality is a good strategy to improve children's diet quality among GDM+ children needs to be further investigated.

Abstract
Bread is a highly consumed food and an important source of nutrients in the diet of Canadians, underlining the need to improve its nutritional quality. The Food Quality Observatory (Observatory) aimed to evaluate the nutritional value of the sliced bread products available in Quebec (Canada), according to their grain type and main flour. Analyses included comparing the bread’s sodium content to Health Canada’s daily values (DV) and sodium voluntary targets, comparing the bread’s fibre content thresholds with the source of fibre mentioned, and assessing whether the main flour was associated with the nutrient content. The nutritional values of 294 sliced breads available in Quebec were merged with sales data (from October 2016 to October 2017), with 262 products successfully cross-referenced. The results showed that 64% of the breads purchased were ‘low’ in fibre (i.e., below 2 g per two slices), while 47% were ‘high’ in sodium (i.e., above 15% DV per two slices). Attention should be paid to 100% refined grain bread and to bread with refined flour as the main flour, since they are great sellers, while showing a less favourable nutrient content. This study shows that there is room for improvement in the nutritional content of Quebec’s bread offer, particularly regarding sodium and fibre content.

Abstract
Background Rates of adherence to available recommendations for dose adjustments in patients with severe obesity are generally low. Hence, antimicrobials are often underdosed in these patients. Antimicrobial stewardship programmes can improve the use of antimicrobials in hospitalised patients. The aim of the study was to analyse the impact of an antimicrobial stewardship programme based on a computerised clinical decision support system for optimal dosing and antimicrobial use in inpatients with severe obesity. Methods This quasi-experimental retrospective study using interrupted time series was conducted in an academic centre in Canada from August 2008 to June 2018. The Antimicrobial Prescription Surveillance System was implemented in August 2010 (intervention 1) and specific rules targeting patients with class III obesity (body mass index ≥ 40 kg/m2) were added in June 2014 (intervention 2). Data were collected from all hospitalised adults receiving antimicrobials which required dose adjustment for severe obesity and were stratified by body mass index. Segmented regression analysis of interrupted time series was used to evaluate the impact of the Antimicrobial Prescription Surveillance System on the proportion of inappropriate days of therapy according to posology and on antimicrobial consumption. Results Overall, 65 205 antimicrobial prescriptions (68% non-obese, 25% class I-II obesity, and 7% class III obesity) were analysed. In patients with class III obesity, the intervention was associated with a decrease in the proportion of inappropriate days of therapy (trend after the first intervention, −0.8% per 2-month period [95% CI −1.1 to −0.5], p < 0.001; intercept, 11.3% [95% CI 8.2 to 14.5], p < 0.001), which led to a reduction of 35% over an eight-year period (from pre-intervention level of 19.1%). Intervention 1 resulted in a downward trend in antimicrobial consumption, followed by an increasing trend after intervention 2. In these patients, the most frequent interventions made by pharmacists targeted posology (46%). Conclusions Antimicrobial Prescription Surveillance System had a positive impact on dosing optimisation and antimicrobial consumption in patients with class III obesity. Improving antimicrobial prescriptions in these patients is important because suboptimal dosing could be associated with unfavourable outcomes.

Abstract
BACKGROUND Outcomes associated with physician responses to recommendations from an antimicrobial stewardship program (ASP) at an individual patient level have not yet been assessed. We aimed to compare clinical characteristics and mortality risk among patients for whom recommendations from an ASP were accepted or refused. METHODS A prospective cohort study was performed with hospitalized adults who received intravenous or oral antimicrobials at a 677-bed academic centre in Canada in 2014-2017. We included patients with an alert produced by a clinical decision support system (CDSS) for whom a recommendation was made by the pharmacist to the attending physician. The outcome was 90-day in-hospital all-cause mortality. RESULTS We identified 3,197 recommendations throughout the study period, of which 2,885 (90.2%) were accepted. The median length of antimicrobial treatment was significantly shorter when a recommendation was accepted (0.26 versus 1.78 d; p < 0.001). Refusal of a recommendation was not associated with mortality (odds ratio 1.32; 95% confidence interval, 0.93 to 1.89; p = 0.12). The independent risk factors associated with in-hospital mortality were age, Charlson Comorbidity Index score, admission to a critical care unit, duration between admission and recommendation, and issuance of a recommendation on a carbapenem. CONCLUSIONS The duration of antimicrobial treatment was significantly shorter when a recommendation originating from a CDSS-assisted ASP program was accepted. Future prospective studies including potential residual confounding variables, such as the source of infection or physiological derangement, might help in understanding whether CDSS-assisted ASP will have a direct impact on patient mortality.

Abstract
The impact of adjusted treatment on clinical outcomes in patients with severe obesity is unclear. This study included adults with severe obesity admitted for bloodstream infections between 2005 and 2015. The patients were grouped according to the percentage of the appropriateness of the dosage of their antimicrobial treatment: 80–100% = good, 20–79% = moderate, and 0–19% = poor. The association between antimicrobial adjustment and a composite of unfavourable outcomes [intensive care unit stay ≥72 h, duration of sepsis >3 days, length of stay ≥7 days or all-cause 30-day mortality] was assessed using logistic regression. Of 110 included episodes, the adjustment was rated good in 47 (43%) episodes, moderate in 31 (28%), and poor in 32 (29%). Older age, Pitt bacteremia score ≥2, sepsis on day 1, and infection site were independent risk factors for unfavourable outcomes. The level of appropriateness was not associated with unfavourable outcomes. The number of antimicrobials, consultation with an infectious disease specialist, blood urea nitrogen 7–10.9 mmol/L, and hemodialysis were significantly associated with adjusted antimicrobial dosing. While the severity of the infection had a substantial impact on the measured outcomes, we did not find an association between dosing optimization and better outcomes.

Abstract
The endocannabinoidome encompasses several fatty acid (FA)-derived mediators, including the endocannabinoid anandamide (AEA) and 2-arachidonoyl-glycerol (2-AG), which served as targets for anti-obesity drug development, and their congener N-acyl-ethanolamines (NAEs) and 2-monoacyl-glycerols (2‑MAGs), which are involved in food intake and energy metabolism. Body weight and fat distribution have been suggested as determinants of peripheral endocannabinoid levels. We aimed at investigating factors, beyond body fat composition, that are associated with circulating NAE and 2-MAG levels in a heterogeneous human population. Plasma NAEs and 2-MAGs were measured using LC–MS/MS in a cross-sectional sample of healthy men and women (n = 195) covering a wide range of BMI and individuals before and after a 2-day Mediterranean diet (n = 21). Circulating levels of all 2-MAGs and NAEs, other than N-oleoyl-ethanolamine (OEA), correlated with body fat mass and visceral adipose tissue (0.26 < r < 0.54). NAE levels were elevated in individuals with elevated fat mass, while 2-MAGs were increased in individuals with predominantly visceral body fat distribution. Dietary intakes of specific FAs were associated with 2-AG and omega-3-FA-derived NAEs or 2-MAGs, irrespective of the body fat distribution. Some gut bacterial families (e.g. Veillonellaceae, Peptostreptococcaceae and Akkermansiaceae) were associated with variations in most NAEs or omega-3-FA-derived 2‑MAGs, independently of fat mass and dietary FA intake. Finally, a 2-day Mediterranean diet intervention increased circulating levels of NAEs and 2-MAGs in agreement with changes in FA intake (p < 0.01). Self-reported intake and short-term dietary intervention increased in oleic acid and EPA and DHA intake as well as certain gut microbiota taxa are associated to circulating NAEs and 2‑MAGs independently of adiposity measures, thus highlighting the potential importance of these variables in determining endocannabinoidome signaling in humans.

Abstract
The regulation of food intake and eating behaviours involves interactions between different systems. The endocannabinoidome, comprising several fatty acid-derived mediators, plays a central role in the regulation of food intake. Alterations of this system have been suggested to intervene in the aetiology of eating disorders. This study aimed to examine the associations between non-pathological eating behaviours and circulating endocannabinoidome mediators in a heterogeneous human population. Plasma 2-monoacyl-glycerol and N-acyl-ethanolamine congeners were measured by LC-MS/MS in a sample of 190 men and women. Eating behaviours were assessed using the Three-Factor Eating Questionnaire (TFEQ) and the Intuitive Eating Scale-2 (IES-2). Following adjustment for body mass index and age, plasma levels of omega-3 polyunsaturated fatty acid-derived 2-monoacyl-glycerols, 2-eicosapentaenoyl-glycerol (2-EPG) and 2-docosapentaenoyl-glycerol (2-DPG), were associated with higher intuitive eating scores (0.15 ≤ rho ≤ 0.20; p < 0.05). These associations were independent of the dietary intake of the fatty acid precursors of these 2-monoacyl-glycerols. However, almost no association was found between plasma levels of N-acyl-ethanolamine congeners and the TFEQ or the IES-2 scores. The results of the present study suggest the association of 2-monoacyl-glycerols, especially 2-EPG and 2-DPG, in the regulation of intuitive eating and the potential implication therein of bioactive lipids.

Abstract
Abstract
Objective
To evaluate very long-term survival of Total Arterial Revascularization (TAR) in patients with severe coronary artery disease (CAD) undergoing Coronary Artery Bypass Grafting (CABG).
Methods
Between January 1992 and December 2017, 13798 patients aged 70 years or less underwent primary isolated CABG with at least two grafts in our department. Patients receiving TAR were matched by propensity-score analysis to the rest of the population. All pre- and peri-operative data were collected prospectively in our institutional database. Long-term survival was assessed using provincial vital statistics data. The primary outcome was very-long time survival, secondary outcomes were operative mortality and early complications.
Results
Propensity-score matching identified 602 pairs with similar preoperative characteristics. In the matched control group, 65.4% and 30.9% of patients received 1 and 2 arterial grafts, respectively, whereas 3 or more arterial grafts were used in 3.6%. Less distal anastomoses (2.57±0.77 vs 3.39±0.97, p<0.0001) were performed in TAR patients, who therefore had a shorter cross-clamping time (44.2±14.7 vs 52.9±19.6, p<0.0001). Operative mortality was similar (0.5% vs 1.0%, p=0.51) and there was no difference in the rate of mediastinitis (2.5% vs 0.8%, p=0.28)for the TAR and matched control groups, respectively. TAR patients were less likely to receive blood transfusions (34.9% vs 40.7%, p=0.04). The average follow-up was 13.4±6.7 years. Cox-adjusted survival was significantly better in patients receiving TAR compared to the matched population, up to 25 years postoperatively (HR 0.87 [0.86–0.88], p<0.0001, Figure 1).

Conclusion
Total arterial revascularization is not associated with increased perioperative risk of complications and provides long-term survival benefits up to 25 years postoperatively.

Abstract
AIMS The objectives of this study were to assess the profile of lifestyle habits among children exposed (GDM+) or unexposed (GDM-) to GDM and to assess whether a healthy lifestyle profile is associated with lower adiposity values among these children. METHODS A total of 105 GDM+ and 38 GDM- children aged 2-14 years were included. Vegetables and fruit intakes were collected using two 24-h dietary recalls. Physical activity and sedentary time were measured with accelerometers. Screen and sleep time were assessed using questionnaires. Weight, height and waist circumference were measured. Body composition was assessed by absorptiometry. RESULTS GDM+ children had lower moderate-to-vigorous physical activity practice (p = 0.043) and fruit intake (p = 0.020) than GDM- children. Among children with an unhealthy lifestyle (meeting 0-2 lifestyle recommendations), GDM+ children had greater percentage of fat mass (p = 0.021) and android fat mass (p = 0.020) than GDM- children. Moreover, among GDM+ children, children with a healthy lifestyle (meeting 3-4 lifestyle recommendations) tended to have lower percentage of fat mass (p = 0.053) and android fat mass (p = 0.071) than those with an unhealthy lifestyle. CONCLUSION Improving lifestyle habits among GDM+ children could represent a promising approach to prevent deteriorated adiposity values.

Abstract
OBJECTIVES To assess the level and factors of compliance of carbapenem prescriptions with guidelines and to determine the impact of an antibiotic stewardship team in a university hospital. PATIENTS AND METHODS Five-month prospective study in the intensive care, surgery, and medicine units to measure the compliance of carbapenem prescriptions with guidelines from French scientific societies; compliance was assessed by an infectious disease specialist warned by the pharmacy, and the prescribers' compliance with the infectious disease specialist's advice was then assessed. RESULTS One hundred and four treatment initiations for 94 patients were included. Prescriptions were mostly empirical (64%), for pulmonary (35%), urinary tract (23%), and intra-abdominal (17%) infections. Prescriptions were mostly made in an intensive care unit (50%), by a junior physician (66%), with the use of imipenem (74%), and were followed by an objective reassessment (80%). Compliance with guidelines (82%) was significantly higher for empirical than documented prescriptions (91% vs 65%, P<0.001). Compliance was higher in intensive care units than medicine units (87% vs 61%, P=0.037). No change in the compliance rate was observed during the study. Compliance with the infectious disease specialist's advice (68%) improved, although not significantly (P=0.066). CONCLUSIONS Because of a higher than expected compliance of carbapenem prescriptions with guidelines and a lower than expected inclusions in the study, we did not show any impact. The diffusion of guidelines and long-term control of carbapenem prescriptions seem to be possible and necessary in hospitals to limit their ecological impact.

Abstract
Children born from mothers with gestational diabetes mellitus (GDM) are at high-risk of obesity and type 2 diabetes. To date, there is a lack of effective strategies to prevent these complications. The aim of this study was to evaluate the association between diet quality and anthropometric and glycemic profiles of children exposed (GDM+) and unexposed (GDM⁻) to GDM. A total of 104 GDM+ and 38 GDM⁻ children were included. Two 24-h dietary recall questionnaires were used to assess dietary intakes. The Healthy Eating Index adapted for the Canadian population (HEI-C) was used to assess diet quality. Spearman correlations adjusted for children's age and sex were computed. Mean age was 6.0 ± 2.5 and 6.8 ± 2.3 years for GDM+ and GDM⁻, respectively (p = 0.03). Total HEI-C score was negatively associated with the android-to-gynoid fat mass ratio (r = -0.29, p = 0.03) and homeostasis model assessment for insulin resistance (HOMA-IR) index (r = -0.22, p = 0.04) in GDM+ children only. The prevalence of being overweight or obese during childhood was 4-fold higher among GDM+ children with a HEI-C score ≤70 compared to GDM+ children with a HEI-C score >70. Results of this study show that a healthy diet is associated with a better cardiometabolic health profile in GDM+ children, including a lower risk of being overweight or obese.

Abstract
BACKGROUND Children exposed to gestational diabetes mellitus (GDM) in utero are at high-risk of obesity. Given that nutritional habits can track from infancy to childhood, the aim of this study was to evaluate the association between the timing of fruit juice introduction in infancy and later consumption of sweet-tasting foods and beverages among children exposed (GDM+) and unexposed (GDM-) to GDM. METHODS A total of 107 GDM+ and 59 GDM- participated in the project. Data on the timing of fruit juice introduction during infancy were retrospectively collected for 62 GDM+ and 32 GDM- children. Current dietary intakes were collected with two 24-hour dietary recall questionnaires. Children were divided into groups according to the median timing of juice introduction (9 months). RESULTS Mean age of children was 6.3 ± 2.6 and 7.6 ± 3.7 years for GDM+ and GDM- children, respectively (p = 0.08). Mean age of fruit juice introduction was similar between groups (p > 0.05). Consuming >1 serving of fruit juice per day was 2.72 times more prevalent among GDM+ children introduced to fruit juice <9 months, compared to GDM+ children introduced ≥9 months (CI: 1.19-6.20). This association was not observed in the GDM- group. The timing of fruit juice introduction was not associated with later consumption of sweets, desserts and sweet-tasting beverages when adjustment for children's age was made among GDM+ and GDM- children. CONCLUSION Early introduction of fruit juice in infant diet is associated with higher prevalence of consumption of >1 serving of fruit juice per day in GDM+ children.

Abstract
The aim of this cohort study was to compare body composition and regional body fat distribution between children exposed (GDM+) or unexposed (GDM-) in utero to gestational diabetes mellitus (GDM) and to investigate the association with the glycaemic and the insulin profile. Data from 56 GDM+ and 30 GDM- were analysed. Height, weight and waist circumference were measured. Total and regional body composition was measured by dual-energy X-ray absorptiometry. Insulin, glucose and HbA1c were obtained from a fasting plasma sample, and the HOMA-IR index was calculated. anova was performed to compare adiposity measures between GDM+ and GDM-. Associations between the glycaemic and insulin profile and adiposity measures were studied using partial Pearson correlations. Mean age was 6.6 ± 2.3 years. Waist circumference, fat mass percentage, android fat mass, android fat mass percentage and android-to-gynoid fat mass ratio were higher among GDM+, and lean mass percentage was lower (P < 0.05). Among GDM+ children, body mass index (BMI) z score, waist circumference, fat mass percentage, android fat mass percentage and android-to-gynoid fat mass ratio were all positively correlated with HbA1C (r = 0.32-0.43, P < 0.05). Prenatal exposure to GDM is associated with increased total and abdominal adiposity. This increased adiposity observed among GDM+ children is associated with an altered glycaemic profile. This study is registered in the Clinical Trials.gov registry (NCT01340924).

Abstract
PURPOSE Women with prior gestational diabetes mellitus (GDM) are at higher risk of type 2 diabetes (T2D). The aim of this study was to investigate the association between fruit and vegetables (FV) intake and abnormal glucose tolerance (AGT) among women with prior GDM. METHODS A total of 281 women with prior GDM have been recruited a mean of 6 years after their pregnancy in this cohort study. FV intake was obtained with a validated food frequency questionnaire (FFQ). Anthropometric and glycemic components were measured during their clinical visit and women were stratified according to normal glucose tolerance (NGT) or AGT. RESULTS A cross-sectional analysis showed that a total of 155 women had NGT and 126 AGT. Women with AGT had significantly lower FV (6.5 ± 0.2) and vegetables servings (3.9 ± 0.2) and tended to have lower fruit servings (2.6 ± 0.2) than women with NGT (7.4 ± 0.2, 4.5 ± 0.2 and 3.0 ± 0.1, respectively) (p = 0.001, p = 0.04 and p = 0.10, respectively, adjusted for age and BMI). FV intake, per one serving increase, was associated with a reduced likelihood of having AGT [OR = 0.88 (0.81-0.97) after adjustment for age and BMI]. Vegetables or fruit intake tended to be associated with a reduced likelihood of having AGT [OR = 0.88 (0.78-1.00) and OR = 0.88 (0.76-1.02), respectively, after adjustment for age and BMI]. CONCLUSIONS Higher intake of FV may be associated with a lower likelihood of AGT among women with prior GDM. Further studies are needed to confirm these results in this high-risk population.

Abstract
Objectives : Prospective audit and feedback interventions are the core components of an antimicrobial stewardship programme. Herein, we describe the sustained impact of an antimicrobial stewardship programme, based on a novel clinical decision-support system (Antimicrobial Prescription Surveillance System; APSS), on antimicrobial use and costs, hospital length of stay (LOS) in days and the proportion of inappropriate antimicrobial prescriptions. Methods A quasi-experimental, retrospective study was conducted using interrupted time series between 2008 and 2013. Data on all hospitalized adults receiving antimicrobials were extracted from the data warehouse of a 677 bed academic centre. The intervention started in August 2010. Prospective audit and feedback interventions, led by a pharmacist, were triggered by APSS based on deviations from published and local guidelines. Changes in outcomes before and after the intervention were compared using segmented regression analysis. Results APSS reviewed 40 605 hospitalizations for 35 778 patients who received antimicrobials. The intervention was associated with a decrease in the average LOS (level change -0.92, P < 0.01; trend -0.08, P < 0.01; intercept 11.4 days), antimicrobial consumption in DDDs/1000 inpatient days (level change -32.4, P < 0.01; trend -1.12, P < 0.02; intercept 243 DDDs per 1000 days of hospitalization), antimicrobial spending in Canadian dollars (level change -19 649, P = 0.01; trend -1881, P < 0.01; intercept $74 683) and proportion of non-concordance with local guidelines for prescribing antimicrobials (level change -2.3, P = 0.04; intercept 41%). Conclusions The implementation of the APSS-initiated strategy was associated with a positive impact on antimicrobial use and spending, LOS and inappropriate prescriptions. The high rate of accepted interventions may have contributed to these results.

Abstract
Children exposed to gestational diabetes mellitus (GDM) in utero are at high risk of developing many health problems such as obesity. There is an urgent need to find new strategies to prevent obesity development among high-risk populations such as those children. Accordingly, the aim of this review was to summarize current knowledge on the postnatal prevention of childhood obesity in offspring born from mothers with GDM. Specifically, this review addresses the impact of breastfeeding, complementary feeding practices as well as dietary intake and physical activity during childhood on obesity risk of children exposed to GDM in utero. Furthermore, breast milk composition of diabetic mothers and its potential impact on growth is discussed. According to the available literature, breastfeeding may reduce obesity risk in children exposed to GDM in utero but a longer duration seems necessary to achieve its protective effect against obesity. Detailed analysis of breast milk composition of mothers with GDM will be necessary to fully understand the relationship between breastfeeding and obesity in this specific population. This review highlights the need for more studies addressing the impact of complementary feeding practices and lifestyle habits during childhood on obesity risk of children exposed to GDM in utero.

Abstract
This randomised controlled trial verified the efficacy of an implementation intentions intervention ( n = 24) to promote fruit and vegetable consumption among childbearing age women at risk for gestational diabetes mellitus against a control condition based on the question–behaviour effect ( n = 26). There was only a significant time effect ( F(2,85) = 5.69, p = 0.0048). Both groups increased their vegetable consumption compared to baseline at 3 months ( p = 0.0022) and 6 months ( p = 0.0042). There were no significant effects on weight, waist circumference and blood glucose levels. Implementation intentions and the question–behaviour effect appear to be effective behaviour change techniques to promote vegetable intake among this high-risk population.

Abstract
Background Short instruments measuring frequency of specific foods, such as fruit and vegetable (FV), are increasingly used in interventions. The objective of the study was to verify the validity and test-retest reliability of such an instrument among pregnant women. Methods Pregnant women from the region of Quebec City, Quebec, Canada, were recruited through e-mails sent to female students and employees of the local university from October 2014 to April 2015. To assess the validity of the fruit and vegetable questionnaire (FVQ) developed by Godin et al. (Can J Public Health 99: 494-498, 2008), pregnant women were asked in a first mailing to complete the FVQ assessing FV intake over the past 7 days and a 3-day estimated food record. A subsample (n = 33) also gave a fasting blood sample and completed a validated semi-quantitative FFQ administered by a trained registered dietitian during a visit at the research center. FV intakes for all instruments were calculated in terms of servings of FV based on Canada’s Food Guide definition of a serving of fruit or vegetable. In order to assess its test-retest reliability, respondents were asked to complete the FVQ 14 days later in a second mailing. Results Forty-eight pregnant women from all three trimesters completed the questionnaires in the first mailing. FV intake assessed using the FVQ was correlated to FV consumption measured using the food record (r = 0.34, p = 0.0180) and the FFQ (r = 0.61, p = 0.0002). Results were similar when controlling for energy intake and the experience of nausea in the past month. Only β-cryptoxanthin was significantly correlated to FV intake assessed by the FFQ when adjusted for the presence of nausea (r = 0.35, p = 0.0471). Data on the test-retest reliability was available for 44 women and the intra-class coefficient for the FVQ was 0.72 at a mean 28-day interval. Conclusions The FVQ has acceptable validity and test-retest reliability values, but seems to underestimate FV servings in pregnant women. It represents an interesting alternative for researchers or clinicians interested in estimating quickly FV intake among pregnant women, such as in large trials or during prenatal visits. The FVQ should however be coupled with other self-reported measures, such as a food record, for assessing precise individual FV intake.

Abstract
Materials with interacting magnetic degrees of freedom display a rich variety of magnetic behaviour that can lead to novel collective equilibrium and out-of-equilibrium phenomena. In equilibrium, thermodynamic phases appear with the associated phase transitions providing a characteristic signature of the underlying collective behaviour. Here we create a thermally active artificial kagome spin ice that is made up of a large array of dipolar interacting nanomagnets and undergoes phase transitions predicted by microscopic theory. We use low energy muon spectroscopy to probe the dynamic behaviour of the interacting nanomagnets and observe peaks in the muon relaxation rate that can be identified with the critical temperatures of the predicted phase transitions. This provides experimental evidence that a frustrated magnetic metamaterial can be engineered to admit thermodynamic phases.

Abstract
Thin films of zinc have been deposited on steel substrates by electrodeposition process and further functionalized with ultra-thin films of commercial silicone rubber, in order to obtain superhydrophobic properties. Morphological feature, by scanning electron microscope (SEM), shows that the electrodeposited zinc films are composed of micro-nano rough patterns. Furthermore, chemical compositions of these films have been analyzed by X-ray diffraction (XRD) and infra-red (IRRAS). An optimum electrodeposition condition, based on electrical potential and deposition time, has been obtained which provides superhydrophobic properties with a water contact angle of 155±1°. The corrosion resistance properties, in artificial seawater, of the superhydrophobic zinc coated steel are found to be superior to bare steel. Similarly, the measured ice adhesion strength on superhydrophobic surfaces, using the centrifugal adhesion test (CAT), is found to be 6.3 times lower as compared to bare steel. This coating has promising applications in offshore environment, to mitigate corrosion and reduce ice adhesion.

Abstract
We study the thermal relaxation of artificial spin ice with photoemission electron microscopy, and are able to directly observe how such a system finds its way from an energetically excited state to the ground state. On plotting vertex-type populations as a function of time, we can characterize the relaxation, which occurs in two stages, namely a string and a domain regime. Kinetic Monte Carlo simulations agree well with the temporal evolution of the magnetic state when including disorder, and the experimental results can be explained by considering the effective interaction energy associated with the separation of pairs of vertex excitations.

Abstract
Abstract
Introduction: Trastuzumab is indicated for the treatment of patients with breast cancer whose tumors overexpress the HER2 protein. Brain metastases have been observed in breast cancer patients, being the highest in women with HER2-overexpressing tumors. The blood-brain barrier, however, may prevent trastuzumab from reaching appropriate concentrations in the cerebrospinal fluid (CSF). Case studies have been reported in which trastuzumab was intrathecally administered for the treatment of metastatic brain cancer in humans. However, no extensive preclinical safety evaluation has been performed for intrathecal application after repeat-dosing in a trastuzumab cross-reactive species using doses equivalent to or higher than those used in patients. To evaluate the potential of local effects, a 28-day toxicology study with weekly intrathecal administration of trastuzumab was performed in cynomolgus monkeys, a trastuzumab cross-reactive species. Preservative-free trastuzumab was used in this preclinical safety study, as caution has been raised for the intrathecal use of benzyl alcohol-containing solutions. Methods: Five male and five female monkeys were evaluated per dose group, of which two monkeys/sex/group were evaluated after a 4-week recovery period. Animals were assigned to 3 groups which received 4 weekly 30-minute intrathecal infusions at 0, 3, or 15 mg per dose at an infusion rate of 1.5 mL/hour. Endpoints evaluated included clinical signs, body weight, appetite, neurological examinations, clinical pathology, gross pathology, and histopathology of the brain (with inclusion of meninges), spinal cord, and infusion site. In addition, CSF and serum samples were collected for toxicokinetic evaluations. Results and Discussion: No test article-related effects on clinical signs, body weight, appetite, neurological examinations, clinical pathology, gross pathology or histopathology were noted. Of note is the absence of demyelination as was discussed as an uncertainty of intrathecally administered proteins. The doses used of 3 and 15 mg per dose resulted in 0.051 and 0.24 mg/g brain doses, respectively. Doses administered in clinical case reports ranged from 5 to 100 mg per dose. For a 1500 g human brain weight, these intrathecal doses would be equivalent to 0.0033 and 0.067 mg/g brain weight. At the high dose of 15 mg, maximum CSF concentrations (Cmax) were as high as 403 µg/mL. The applied doses and CSF concentrations achieved in the current study greatly exceeded those reported in patients (6.4 µg/mL at an intrathecal dose of 20 mg). Conclusion: The results of this 4-week toxicology study in monkeys with the results of the clinical case studies support future studies to evaluate intrathecal application of trastuzumab in patients with brain metastasis in HER2-positive breast cancer.

Abstract
BACKGROUND The durability of bioprosthetic valves is limited by structural valve degeneration (SVD) leading to bioprostheses (BPs) stenosis or regurgitation. We hypothesized that a lipid-mediated inflammatory mechanism is involved in the SVD of BPs. MATERIAL AND METHODS Eighteen Freestyle stentless BP valves were explanted for SVD at a mean time of 5.9 +/- 3 years after implantation and were analysed by immunohistochemistry and transmission electron microscopy (TEM). RESULTS The mean age of the patients was 65 +/- 8 years and there were 11 male and seven female patients. Two of the 18 BPs had macroscopic calcification, whereas the other valves had minimal or no macroscopic calcification. Tears at the commissures leading to regurgitation was present in 16 BPs. Immunohistochemistry showed the presence of oxidized low-density lipoprotein (ox-LDL) and glycosaminoglycans in the fibrosa layer of 13 BPs. Areas with ox-LDL were infiltrated by macrophages (CD68(+)) co-expressing the scavenger receptor CD36 and metalloproteinase-9 (MMP-9). Zymogram showed the active form of MMP-9 within explanted BPs. EM studies revealed the presence of lipid-laden cells featuring foam cells and fragmented collagen. Nonimplanted control BPs obtained from the manufacturer (n = 4) had no evidence of lipid accumulation, inflammatory cell infiltration or expression of MMP9 within the leaflets. CONCLUSIONS These results support the concept that lipid-mediated inflammatory mechanisms may contribute to the SVD of BPs. These findings suggest that modification of atherosclerotic risk factors with the use of behavioural or pharmacological interventions could help to reduce the incidence of SVD.
