Abstract
Over 85% of parents use social media; however, limited research has investigated the associations between parental social media use and food parenting practices. The objectives of this study were to: 1) describe how mothers and fathers use social media focused on topics related to child feeding and family meals; and 2) examine associations between parental social media use focused on child feeding and family meals and mothers' and fathers' food parenting practices. Data were obtained from 179 mothers and 116 fathers of children aged 3-8 years enrolled in a family-based obesity prevention intervention. We used descriptive statistics to describe parents' social media use in relation to child feeding and family meals and linear regressions with generalized estimating equations to explore associations between parents' social media use and food parenting practices. Models were stratified by parent gender and adjusted for household income, parent ethnicity, parent age, child sex, and intervention status. A higher percent of mothers than fathers reported using social media to seek information related to child feeding and family meals (64.8% mothers; 25.0% fathers) and to share and compare family meals and food choices (41.9% mothers; 19.8% fathers). While social media use was not associated with food parenting practices in mothers, fathers' social media use to share and compare family meals and food choices was associated with negative food parenting practices, i.e., greater use of food for emotional regulation (β = 0.37, p = 0.02) and greater use of food for reward (β = 0.34, p = 0.02). Study results can inform strategies to promote healthy social media use among parents of young children.

Abstract
We aimed to evaluate the impact of a web-based school nutrition intervention on eating behavior traits, body weight concern, body size perception and body size dissatisfaction in adolescents. Ten classes of secondary students in Canada (13.6 ± 0.8 years) were randomized into an intervention (n = 162 students) or control group (n = 75 students). Adolescents in the intervention, conducted between 2011 and 2013, participated in an online nutrition challenge to increase their consumption of vegetables, fruits and dairy products using a web-based platform over six weeks. Measurements were taken at baseline (PRE) and post-intervention (POST). No significant negative changes were observed between the intervention and control groups for eating behavior traits, body weight concern, body size perception and dissatisfaction. However, results suggest a trend for a positive effect of the intervention on susceptibility to hunger in boys (group × time interaction, p = 0.10). Specifically, boys experienced a reduction in their susceptibility to hunger in response to the intervention (PRE: 6.1 ± 3.8, POST: 4.8 ± 3.7, p = 0.009). An intervention aimed at improving the eating habits of adolescents did not negatively influence body size preoccupations. In response to the intervention, boys tended to show a lower susceptibility to hunger, which might help them to prevent overeating and adopt healthy eating habits.

Abstract
PURPOSE/OBJECTIVE(S) To report the feasibility and early toxicities of dose-escalated SCRT in rectal cancer patients receiving total neoadjuvant therapy (TNT). MATERIALS/METHODS This retrospective cohort study included 13 patients treated via a TNT approach (guided by RAPIDO trial) for locally advanced rectal cancer. The planned radiation was a standard dose of 25 Gy in 5 fractions to the primary tumor and at-risk lymphatics (PTV_Low). The dose-escalation was achieved via SIB delivering 30 Gy to the primary tumor (PTV_Mid) and 40 Gy (PTV_High) to inoperable lateral pelvic lymph nodes (LN), when present, over 5 fractions. A 5 mm margin was added to the rectal tumor and lateral pelvic LN to create the SIB targets. All patients were planned for intensity modulated radiation therapy via Varian EclipseTM (Palo Alto, CA) treatment planning system. Prior to treatment patients underwent kV and cone beam CT (CBCT) imaging for image guidance. Shifts were not performed solely to accommodate the boost target volume if it was felt to compromise the coverage of at-risk lymphatics. Normal tissue constraints were prioritized over boost coverage. Early toxicities were assessed for 30 days following treatment and graded using the Common Terminology Criteria for Adverse Events version 5.0. Offline image review was performed to determine the frequency at which the gross tumor volume (GTV) was captured within the 5 mm planning target volume (PTV_Mid) margin on daily CBCT scans. If a misalignment (tumor crossing outside of PTV_High) was discovered, the direction of misalignment (lateral/anterior/posterior) and location (superior/inferior) in relation to the superior border of the pubic symphysis was documented. An additional 5 mm margin from the PTV_Mid was created to determine if this would have captured the target. RESULTS Twelve of the 13 patients were ≥ 30 days from treatment completion and were included in the toxicity analysis. The most common grade 1-2 toxicities were proctitis and diarrhea, which occurred in 42% and 25% of patients, respectively. Other toxicities were new onset rectal bleeding (17%), rectal pain (17%) and radiation dermatitis (8%). No grade 3+ toxicities were observed. Given five fractions for each of the 13 patients, a total of 65 CBCTs were reviewed and compared to the planning CT obtained at simulation. A total of 14/65 (22%) misalignments were discovered across six patients. All occurred above the superior edge of the pubic symphysis. Four misalignments were multi-directional. Nine were anterior, 6 were lateral, and 1 was posterior. Twelve of the 14 (86%) would have been covered within the additional 5 mm expansion volume. CONCLUSION In this cohort of patients who received dose-escalated SCRT, the composite rate of acute toxicity was expectedly low. Feasibility of treatment delivery was established but could be improved upon with an addition 5 mm expansion, specifically in locations cranial to the superior edge of the pubic symphysis.

Abstract
Introduction Whether a late distribution of food intake impacts obesity through increased energy intake remains uncertain and the behavioural characterization of late eating needs to be further investigated. The first objective of this study was to assess the associations between late eating and body mass index (BMI) and total energy intake (TEI), and whether TEI mediates the association between late eating and BMI. The second objective was to assess the associations between late eating and eating behaviour traits or psychosocial factors and whether eating behaviour traits mediate the association between late eating and TEI. Methods Baseline data from 301 individuals (56% women, age = 38.7 ± 8.5 years; BMI = 33.2 ± 3.4 kg/m2), who participated in four weight loss studies were used in this cross-sectional study. Total energy intake was assessed using a three-day food record from which the percentage of TEI after 17:00 and after 20:00 was calculated. Eating behaviour traits and psychosocial factors were assessed with questionnaires. Pearson correlations and mediation analyses adjusted for age, sex, underreporting of energy intake, sleep duration and bedtime were performed. Results Percent TEI after 17:00 and after 20:00 were associated with TEI (r = 0.13, p = 0.03 for both), and TEI mediated the association between percent TEI after 17:00 and BMI (β = 0.01 ± 0.01, 95% CI: 0.001, 0.02). Percent TEI after 17:00 was associated with disinhibition (r = 0.13, p = 0.03) and percent TEI after 20:00 was associated with susceptibility to hunger (r = 0.13, p = 0.03), stress (r = 0.24, p = 0.002) and anxiety (r = 0.28, p = 0.0004). In women, disinhibition mediated the association between percent TEI after 17:00 and TEI (β = 3.41 ± 1.43, 95% CI: 0.92, 6.47). Susceptibility to hunger mediated the association between percent TEI after 20:00 and TEI (β = 0.96 ± 0.59, 95% CI: 0.02, 2.34) in men and women. Conclusion Late eating is associated with TEI and suboptimal eating behaviours which could contribute to explaining the association between timing of food intake and obesity.

Abstract
While engaging in Mind-Body Practices (MBPs) may be related to better diet quality, its association with eating behaviours is unclear. This cross-sectional study explores whether eating behaviour traits and regulation style of eating behaviours mediate the association between MBP engagement and diet quality. A total of 418 women and 482 men, aged between 18 and 65 years and recruited as part of the PREDISE study cohort, reported whether they currently practice one or more MBP (e.g., yoga or meditation). Canadian Healthy Eating Index (C-HEI) was calculated from three 24h dietary recalls. Intuitive Eating Scale (IES-2), and Regulation of Eating Behaviour Scale were completed online. Mann-Whitney tests were conducted to compare C-HEI scores of individuals who currently engage in MBPs (practitioners) to those who do not (non-practitioners). Multiple regression analyses and bootstrapping were performed to test whether eating behaviours and regulation style of eating behaviours mediate the association between MBPs and diet quality. Overall, 88 women and 43 men were practitioners. They had higher C-HEI scores than non-practitioners (62.9 ± 13.0 vs. 55.6 ± 14.3; p = 0.001). Parallel mediation model showed significant indirect effects of the IES-2 subscale relating to Body-Food Choice Congruence (β = 1.57, SE = 0.41, 95% CI: 0.86, 2.43), self-determined motivation (β = 1.51, SE = 0.39, 95% CI:0.81, 2.32) and non-self-determined motivation (β = 0.39, SE = 0.21, 95% CI: 0.03, 0.85) on the association between practitioner status and C-HEI. These findings suggest that the current practice of MBPs is associated with better diet quality, mainly through practitioners' higher intuitive eating skills and more self-determined regulation of eating behaviours. Further studies should investigate the potential impacts of MBPs on the development and maintenance of positive eating habits.

Abstract
The main aim of this study was to evaluate the effects of Na intake and cardiorespiratory fitness (CRF) on body composition. The study was also intended to assess whether Na intake and/or CRF mediate the genetic susceptibility to obesity. Analyses were performed on a sample of 526 adult participants from the Quebec Family Study for whom a complete data set was available for nutrient and energy intake, CRF and body composition variables. The effects of Na, CRF and their interaction were analysed by comparing sex-specific tertiles using general linear mixed models. In both males and females, we observed a significant effect of Na intake and CRF on all body composition variables. However, in females only, we found that the effect of Na intake on body composition variables varies according to CRF level such that high Na intake was associated with increased body fatness, but only in females with low CRF. This interaction effect remained significant after statistical adjustment for total sugar, fat and energy intake. Using mediation analysis, we also found Na intake and CRF to be significant mediators of the relationship between a polygenic risk score of obesity based on > 500 000 genetic variants and BMI or waist circumference. In conclusion, the current study shows that Na intake influences body composition via mechanisms that interact with aerobic fitness, especially in females. Furthermore, both Na intake and CRF seem to be involved in the expression of the genetic susceptibility to obesity.

Abstract
Whether eating behaviour traits represent factors that could explain the susceptibility to overeating in individuals with low satiety responsiveness remain to be extensively examined. This study aimed to assess if eating behaviours mediate the association between satiety responsiveness and energy intake. Baseline data from individuals with overweight or obesity (n = 303; age = 38.7 ± 8.4 years; BMI = 33.2 ± 3.4 kg/m2, 56% women) who participated in four weight-loss studies were included in this cross-sectional study. Satiety responsiveness was determined by the satiety quotient (SQ) based on fullness sensations in response to a standardized breakfast. Energy intake was self-reported in a three-day food record and measured by an ad libitum buffet meal. Eating behaviours were assessed with questionnaires. Mediation analyses adjusted for age and sex, and for underreporting for the food record, were performed using a regression-based and bootstrapping approach. The association between SQ and self-reported total energy intake was mediated by susceptibility to hunger (β = -2.51 ± 1.26, 95% CI, -5.38 to -0.52) and its subscales, internal and external locus of hunger (β = -2.00 ± 1.10, 95% CI, -4.50 to -0.28 and β = -2.42 ± 1.29, 95% CI, -5.30 to -0.30, respectively). Susceptibility to hunger (β = -2.71 ± 1.13, 95% CI, -5.29 to -0.84), internal and external locus of hunger (β = -1.84 ± 0.95, 95% CI -4.00 to -0.30 and β = -3.42 ± 1.31, 95% CI, -6.39 to -1.24, respectively), cues that may trigger food cravings (β = -5.43 ± 2.91, 95% CI, -11.83 to -0.44) and state-craving as a physiological state (β = -4.31 ± 2.51, 95%CI, -10.14 to -0.44) also mediated the association between SQ and measured energy intake. These results suggest that susceptibility to hunger and food cravings partly explained the susceptibility to overeating among individuals with low satiety responsiveness. Interventions targeting susceptibility to hunger and food cravings may thus be helpful to prevent overeating among these individuals.

Abstract
BACKGROUND The importance of adopting healthy eating habits at a young age to prevent obesity and chronic diseases justifies the need for effective interventions. OBJECTIVE This study evaluated the impact of a family web-based nutrition intervention on vegetable and fruit (V/F) and dairy product (DP) consumption, nutrient intakes, diet quality and BMI or BMI z-scores. METHODS Forty-three families with children aged 8-16 years were randomized to either the family web-based intervention, or web-based general nutrition guidelines (control) over 8 weeks. Nutritional variables were assessed with three-day dietary records while anthropometry (body weight and height) was assessed with standardized measures at baseline (PRE), immediately after the intervention (POST 1) and 3-6 months after the intervention (POST 2). Linear mixed models for repeated measures were used to assess the main effects and their interactions followed by post hoc tests. RESULTS The intervention had an effect on DP, total sugar, potassium, magnesium, and calcium in children (Group x Time, P = 0.02 to 0.03) and on DP, V/F juice, carbohydrates, total sugar, saturated fat, protein and calcium in parents (Group x Time, P = 0.01 to 0.03). Post hoc tests revealed children in the intervention group increased their DP intakes immediately after the intervention (POST1) but decreased at follow-up (POST2). No effect of the intervention on V/F, diet quality or BMI was observed. CONCLUSION Compared to general nutrition guidelines, this family web-based nutrition intervention had a modest effect on nutrient intakes, but beneficial effect on DP intakes in the short term.

Abstract
Abstract
Background
Pulmonary vein isolation (PVI) is the cornerstone of atrial fibrillation (AF) ablation. Data regarding additional substrate modification has been conflicting, both in paroxysmal and persistent atrial fibrillation.
Purpose
To assess the effect of additional linear substrate modification during de novo AF ablation on AF recurrence.
Methods
We reviewed 1575 AF ablations in 1254 patients from January 2013 to June 2021 at a single academic medical center. There were 1096 de novo ablations. We defined substrate modification as linear ablations including cavotricuspid isthmus (CTI), superior vena cava isolation, intercaval line, mitral isthmus, and left atrial roof and floor lines. We evaluated clinical and procedural characteristics to identify risk factors for AF recurrence and complications. Patients were followed for a minimum of 6 months.
Results
The 1096 de novo ablations included 65.5% males with mean age 61.1 years, mean BMI 31.3, 81.8% paroxysmal AF and 18.2% persistent AF. There were four AF ablation subgroups: PVI alone (41.6%), PVI and CTI ablation (37.1%), PVI with CTI and additional substrate modification (15.6%), and PVI with substrate modification without CTI ablation (5.7%). Overall, AF recurred in 36.9% cases. AF recurrence with PVI only ablation was 41% compared to 32.7% in patients with PVI and CTI ablation (p=0.02). When looking at patients with paroxysmal and persistent AF, results were similar, with decreased AF recurrence with the addition of CTI ablation in both paroxysmal (37.3% v. 29.2%, p=0.03) and persistent AF (58.1% v. 40.0%, p=0.02). Additional substrate modification did not result in significant difference in outcome in either paroxysmal or persistent AF (Figure 1).
Conclusions
In de novo AF ablations, addition of CTI ablation to de novo PVI ablation is associated with lower AF recurrence in both paroxysmal and persistent AF. Additional linear substrate modification did not impact outcomes.

Abstract
Abstract
Background
Atrial fibrillation (AF) ablation is an outpatient procedure with traditionally an overnight hospital observation (OHO). Recently, there has been a trend towards same day discharge (SDD).
Purpose
Compare AF ablation procedure safety outcomes with SDD vs. OHO.
Methods
We reviewed consecutive AF procedures performed from January 2013 to June 2021 at a single academic center. Patients underwent OHO until June 2020, after which patients had SDD whenever feasible. Adverse events were assessed at three months, which included pericardial effusion, pericarditis, post-procedure hypotension, embolic events, and vascular complications. We also assessed emergency department (ED) visits and procedure-related hospital admissions.
Results
There were 1254 patients who underwent 1575 AF ablations. 1440 patients underwent OHO and 135 had SDD. Mean age was 62.2 years, BMI 33 kg/m2, 65% were male, and 27.6% had persistent AF, without significant differences in baseline characteristics between OHO and SDD. We found that SDD was not associated with increased complications (OHO 0.20% v. SDD 0.49%; p>0.05), ED visits, or hospital admissions (2% v. 5%; p>0.05) (Figure 1, 2). There were no gender or age-related disparities in all outcomes (p>0.05).
Conclusion
SDD protocol after AF ablation is feasible and not associated with higher incidence of complications, ED visits, and procedure-related hospitalizations.

Abstract
Abstract
Background
There are conflicting reports in the literature regarding whether body-mass index (BMI) influences the success and procedural complication rates of atrial fibrillation (AF) ablation.
Purpose
To determine if differences in BMI affect AF ablation outcomes
Methods
At a single academic center, AF ablation procedures were reviewed from 2013 to 2021. Primary outcomes were AF recurrence (after a 90 day blanking period), procedure-related complications, emergency department visits or hospital admission (ED/HOSP). Patients had a minimum of 6 months follow-up
Results
We analyzed 1569 AF ablation consecutive procedures (1093 de novo, 476 repeat ablation) using either radiofrequency or cryoablation. The study population was 65% male with a mean age 62 years, with 28% persistent AF. BMI was separated into three cohorts: <25 kg/m2 (N=218), 25–30 kg/m2 (N=547), and >30 kg/m2 (N=804). There were no significant differences in the type of AF, left atrial diameter, or left ventricular ejection fraction in the BMI subgroups. There was a direct relationship between the prevalence of co-morbid conditions and increasing BMI: hypertension (49.1%, 59.9%, 60.2%; p 0.04), diabetes (6.4%, 13.5%, 21.3%; p 0.01), and obstructive sleep apnea (5.5%, 10.8%, 26.7%; p<0.01). There were no significant differences in AF recurrence, procedural complications or ED/HOSP among the BMI cohorts (p>0.05) (Figure 1). No gender related disparities were noted in outcomes (p>0.05).
Conclusion
Higher BMI was not associated with AF recurrence, complications, or ED/HOSP after AF ablation despite a higher prevalence of comorbid medical conditions

Abstract
PURPOSE The Adult Eating Behaviour Questionnaire (AEBQ) is a newly developed questionnaire adapted from the widely used Child Eating Behaviour Questionnaire. This questionnaire assesses four food approach scales, namely hunger, food responsiveness, emotional overeating (EOE) and enjoyment of food, and four food avoidance scales, namely satiety responsiveness (SR), emotional undereating (EUE), food fussiness and slowness in eating (SE). This study aimed to validate a French version of the AEBQ in controlled conditions among French-speaking adults from Quebec, Canada. METHODS The AEBQ was pre-tested through structured interviews with 30 individuals. Participants of the validation study (n = 197, aged 19-65 years) had their height and weight measured and completed the AEBQ, Three-Factor Eating Questionnaire (TFEQ) and Intuitive Eating Scale-2 to assess factorial structure, internal consistency and construct validity. Test-retest reliability over 2 weeks was assessed among 144 participants. RESULTS Confirmatory factor analysis indicated an excellent model fit (NNFI = 0.98, CFI = 0.98, RMSEA = 0.03, χ2/df = 1.17) and provided support for the use of the original 8-factor questionnaire. Internal consistency was adequate for most scales (Cronbach's alpha = 0.66-0.94) and moderate to excellent test-retest reliability was observed for all scales (ICC = 0.70-90). Women showed higher levels of EOE and SR, and individuals with overweight and obesity showed higher levels of EOE and lower levels of EUE and SE. Construct validity was also supported by expected correlations with disinhibition and susceptibility to hunger from the TFEQ and intuitive eating. CONCLUSION This study indicates that the French AEBQ is a valid and reliable tool to measure eating behaviours in the adult population of Quebec. LEVEL OF EVIDENCE Level III: Evidence obtained from well-designed cohort or case-control analytic studies. The data are cross-sectional, but all measurement were undertaken in controlled laboratory conditions and the study provided new information.

Abstract
BACKGROUND Obesity results from complex interactions between genetic susceptibility to weight gain and poor eating and lifestyle behaviors. The approach that has been traditionally used in genetics to investigate gene-environment/lifestyle interaction in obesity is based on the concept of moderation, or effect modification. Another approach called mediation analysis can be used to investigate gene-environment interaction in obesity. The objective of this review article is to explain the differences between the concepts of moderation and mediation and summarize the studies that have used mediation analysis to support the role of eating or lifestyle behaviors as putative mediators of genetic susceptibility to obesity. SUMMARY Moderation is used to determine whether the effect of an exposure (genes associated with obesity) on an outcome (obesity phenotype) differs in magnitude and/or direction across the spectrum of environmental exposure. Mediation analysis is used to assess the extent to which the effect of the exposure on the outcome is explained by a given set of hypothesized mediators with the aim of understanding how the exposure could lead to the outcome. In comparison with moderation, relatively few studies used mediation analyses to investigate gene-environment in obesity. Most studies found evidence that traits related to appetite or eating behaviors partly mediated genetic susceptibility to obesity in either children or adults. Key messages: Moderation and mediation represent two complementary approaches to investigate gene-environment interaction in obesity and address different research questions pertaining to the cause-effect relationship between genetic susceptibility to obesity and various obesity outcomes. More studies relying on mediation are needed to better understand the role eating and lifestyle habits in mediating genetic susceptibility to obesity.

Abstract
Hintergrund Anhand der vom Institut für das Entgeltsystem im Krankenhaus (InEK) kalkulierten Fallpauschalen ist ein Vergleich der eigenen Leistungsdaten gegenüber allen nach der DRG („diagnosis-related groups“, diagnosebezogene Gruppen) abrechnenden Kliniken in Deutschland möglich. Ziel der vorliegenden Arbeit ist es, Über- oder Unterschreitungen von CT- oder MRT-Untersuchungen im Vergleich mit den InEK-Daten zu ermitteln und mögliche Verbesserungspotenziale zu erschließen. Methodik Die InEK-Kalkulationsdaten für 2021 wurden zur Bildung von Vergleichskennzahlen der CT- und MRT-Diagnostik auf DRG-Ebene herangezogen. Auf Fallebene wurden Daten eines universitären Maximalversorgers auf Gesamthaus‑, Klinik‑, DRG- und Hauptdiagnosen-Ebene gegenübergestellt. Ergebnis Auf Gesamthausebene zeigt sich eine Überschreitung der MRTs um 1025 und der CTs um 371 gegenüber InEK. Die Analyse nach Fachabteilungen ergab am Beispiel der Neurologie eine Überschreibung der MRTs gegenüber InEK um 489 sowie eine Unterschreitung der CTs um \documentclass[12pt]{minimal}

\begin{document}$$-$$\end{document}-620. Der Benchmark der DRGs zeigte in beiden Untersuchungsmodalitäten insbesondere die DRG B70B als Treiber der Abweichungen (MRT + 42,7; CT − 273). Die identifizierten Abweichungen lassen sich auf Hauptdiagnosen-Ebene weiter herunterbrechen. Diskussion Das Bewusstsein über eine überdurchschnittliche Schnittbilddiagnostik kann einen wichtigen Anstoß zur Weiterentwicklung der Behandlungspfade einer Klinik bilden. Die Methodik des InEK-Benchmarks ist für jedes Krankenhaus anwendbar und identifiziert valide bereits erbrachte Leistungen und Prozesse mit einem Verbesserungspotenzial. Die Prüfung beeinflussender Faktoren sowie die Bewertung durch Mediziner und Kaufleute bildet die Voraussetzung für Akzeptanz und Erfolg der daraus generierten Maßnahmen.

Abstract
Although nutrition influences performance, many athletes, including football players, do not meet nutritional requirements for their sport. The objective of this study was to determine the impact of a nutrition intervention combining nutrition education and cooking workshops on nutrition knowledge, intention, and perceived behavioral control in the preparation of healthy meals, dietary intakes, and diet quality in male university football players. Athletes ( n = 23; age: 22 ± 1 year) were randomly assigned to an intervention (2 h/week) ( n = 13) or control group ( n = 10) over three weeks. Questionnaires were completed before (pre), immediately after (post 1), and two months after the intervention (post 2). Dietary intakes and diet quality were evaluated from three web-based 24-h dietary recalls per visit. Mixed linear models for repeated measures with Tukey’s post hoc test were performed to determine the effects of the intervention on all outcomes. There was a group by time interaction for nutrition knowledge ( p = 0.002) that was higher immediately after and two months after the intervention compared to the control group. No differences on other outcomes were observed. Combining nutrition education and cooking workshops improved nutrition knowledge, but did not affect intention and perceived behavioral control in the preparation of healthy meals, dietary intakes, and diet quality in male university football athletes.

Abstract
BACKGROUND Recent studies showed that eating behaviors such as disinhibition, emotional and external eating, and snacking mediate genetic susceptibility to obesity. It remains unknown if diet quality and intake of specific food groups also mediate the genetic susceptibility to obesity. OBJECTIVE This study aimed to assess if diet quality and intakes of specific food groups mediate the association between a polygenic risk score (PRS) for BMI and BMI and waist circumference (WC). We hypothesized that poor diet quality, high intakes of energy-dense food groups, and low intakes of nutrient-dense food groups mediate the genetic susceptibility to obesity. METHODS This cross-sectional study included 750 participants (56.3% women, aged 41.5 ± 14.9 y, BMI 27.8 ± 7.5 kg/m2) from the Quebec Family Study. A PRSBMI based on >500,000 genetic variants was calculated using LDpred2. Dietary intakes were assessed with a 3-d food record from which a diet quality score (i.e. Nutrient Rich Food Index 6.3) and food groups were derived. Mediation analyses were conducted using a regression-based and bootstrapping approach. RESULTS The PRSBMI explained 25.7% and 19.8% of the variance in BMI and WC, respectively. The association between PRSBMI and BMI was partly mediated by poor diet quality (β = 0.33 ± 0.12; 95% CI: 0.13, 0.60), high intakes of fat and high-fat foods (β = 0.46 ± 0.16; 95% CI: 0.19, 0.79) and sugar-sweetened beverages (β = 0.25 ± 0.14; 95% CI: 0.05, 0.60), and low intakes of vegetables (β = 0.15 ± 0.08; 95% CI: 0.03, 0.32), fruits (β = 0.37 ± 0.12; 95% CI: 0.17, 0.64), and dairy products (β = 0.17 ± 0.09; 95% CI: 0.02, 0.37). The same trends were observed for WC. CONCLUSIONS The genetic susceptibility to obesity was partly mediated by poor diet quality and intakes of specific food groups. These results suggest that improvement in diet quality may reduce obesity risk among individuals with high genetic susceptibility and emphasize the need to intervene on diet quality among these individuals.

Abstract
BACKGROUND AND PURPOSE Cone-beam CT is being increasingly used in head and neck imaging. We compared cone-beam CT with multidetector CT to assess postoperative implant placement and delineate finer anatomic structures, image quality, and radiation dose used. MATERIALS AND METHODS This retrospective multicenter study included 51 patients with cochlear implants and postoperative imaging via temporal bone cone-beam CT (n = 32 ears) or multidetector CT (n = 19 ears) between 2012 and 2017. We evaluated the visualization quality of single electrode contacts, the scalar position of the electrodes, cochlear walls, mastoid facial canal, metallic artifacts (using a 4-level visual score), and the ability to measure the insertion angle of the electrodes. The signal-to-noise ratio and radiation dose were also evaluated. RESULTS Cone-beam CT was more sensitive for visualizing the scalar position of the electrodes (P = .046), cochlear outer wall (P = .001), single electrode contacts (P < .001), and osseous spiral lamina (P = .004) and had fewer metallic artifacts (P < .001). However, there were no significant differences between both methods in visualization of the modiolus (P = .37), cochlear inner wall (P > .99), and mastoid facial canal wall (P = .07) and the ability to measure the insertion angle of the electrodes (P > .99). The conebeam CT group had significantly lower dose-length product (P < .001), but multidetector CT showed a higher signal-to-noise ratio in both bone and air (P = .22 and P = .001). CONCLUSIONS Cone-beam CT in patients with cochlear implants provides images with higher spatial resolution and fewer metallic artifacts than multidetector CT at a relatively lower radiation dose.

Abstract
This study aimed to measure the influence of the Chefs in Action program (3 cooking workshops) on cooking skills, nutrition knowledge, and attitudes towards healthy eating in children attending summer day camps and compare it with a single cooking workshop. Groups of children (8–12 years) were randomly assigned to the intervention group (n = 25) or to 1 of 3 comparison groups performing a single workshop (group 1, n = 16; group 2, n = 36; group 3, n = 24). Two dietitians evaluated cooking skills during the workshops. Nutrition knowledge and attitudes towards healthy eating were assessed before and after the intervention. No improvement in cooking skills was observed in the intervention group (P = 0.25). The intervention group’s cooking skills score was significantly higher than comparison group 1 (P < 0.001). Nutrition knowledge was significantly improved in the intervention group and the comparison group 3 (P < 0.0001) but no effect on attitudes towards healthy eating was observed (Pgroup × time = 0.36). In conclusion, the Chefs in Action program positively impacted nutrition knowledge in children. The results also suggest that the type of recipe may influence nutrition knowledge and cooking skills. Further studies are needed to better assess the degree of difficulty required in cooking workshop recipes to improve cooking skills in children.

Abstract
Individual variability in weight loss in response to a weight loss intervention is commonly observed. Recently, the timing of food intake has been identified as one possible factor implicated in obesity and weight loss. The objective of this study was to further characterize low weight loss responders by assessing the pre-diet distribution of daily energy and macronutrient intakes. A pooled cohort of men and women (n = 122; aged 39.1 ± 8.2 years; body mass index [BMI] 33.1 ± 3.8 kg/m2 ) who participated in a 12 to 15 week energy-restricted intervention (-500 to -700 kcal/d) were included in this study. Participants were categorized into two weight loss groups (ie, low [-1.3 ± 2.3 kg] and high [-6.1 ± 2.1 kg] weight loss). Food intake and distribution of energy and macronutrient intakes were assessed using a 3-day food record at baseline. The daily distribution of energy intake (% of total energy intake) was similar in the two weight loss groups with the exception of the low weight loss group who consumed a slightly lower proportion of their total energy intake before 9:00 am compared with the high weight loss group (12.5% ± 5.8% vs 15.0% ± 6.6%, respectively, P = .03). In the low weight loss group, the percentage of energy intake consumed after 8:00 pm was positively associated with total energy intake (r = 0.27, P = .04). The results of this study suggest that the timing of food intake measured prior to a weight loss intervention does not permit the characterization of low weight loss responders.

Abstract
BACKGROUND Coaches are considered as an important source of nutrition information by their athletes. However, their knowledge in this area is often insufficient for proper guidance and may lead to the dissemination of misinformation regarding sports nutrition. The aim of this study was to assess coaches' intentions as well as psychosocial determinants underlying their intentions to provide sports nutrition recommendations to their high school athletes. METHODS Coaches (n = 47) completed a Web-based questionnaire based on the theory of planned behaviour, to assess their intentions to provide three different sports nutrition recommendations and their determinants. Multiple regression analyses were used to identify the variables that were most strongly related to the intentions. RESULTS Forty-six, 44.7 and 91.9% of coaches had the intention to recommend a higher consumption of foods rich in carbohydrates, foods rich in proteins and an increase in hydration to their athletes, respectively. Subjective norm was the only significant determinant of coaches' intention to recommend a higher consumption of foods rich in carbohydrates (R2 = 53.7%, β = 0.73 ± 0.12, P < 0.0001). Subjective norm and perceived behavioural control were significantly associated with coaches' intentions to recommend a higher consumption of foods rich in proteins (R2 = 25.9%, β = 0.50 ± 0.16, P = 0.002 and R2 = 17.2%, β = 0.39 ± 0.17, P = 0.01, respectively) and an increase in hydration (R2 = 26.8%, β = 0.38 ± 0.13, P = 0.001 and R2 = 46.3%, β = 0.58 ± 0.11, P < 0.0001, respectively). CONCLUSIONS The results of this study suggest that subjective norm and perceived behavioural control represent important determinants of coaches' intentions to provide recommendations on sports nutrition. These findings should be considered in future interventions aimed at facilitating proper general sports nutrition recommendations provided by coaches to their athletes.

Abstract
BACKGROUND Patients with single-sided deafness (SSD) are limited by their asymmetric hearing in various areas of everyday life. OBJECTIVE The aim of this investigation was to perform an age-correlated comparison of the hearing threshold of the better ear of SSD patients with a normal-hearing (NH) reference cohort. In addition, the potential influence of etiology, duration of deafness, and cochlear implantation (CI) of the poorer ear on the peripheral hearing ability of the better ear was investigated. MATERIALS AND METHODS In a multicenter study, the mean bone conduction hearing threshold of the better ear of 413 adult SSD patients was compared with that of an NH cohort drawn from ISO 7029:2017 for the frequencies 0.5, 1, 2, and 4 kHz. RESULTS SSD patients showed significantly poorer hearing in the better ear compared to the age-correlated group of NH subjects. CI, duration of deafness, and etiology had no significant effect on the hearing ability of the better ear. CONCLUSION The origin of the poorer hearing of the better-hearing ear of SSD patients compared to an age-correlated NH cohort is still unclear. It is most likely a combination of different anatomical, immunological, etiological, and microcirculatory causes, which lead to poorer hearing of the better-hearing ear in SSD patients.

Abstract
Abstract
Background
Cardiovascular mortality is higher in developing countries. Part of that is suboptimal testing. Cardiac magnetic resonance (CMR) is the gold standard for measuring structure, function of the heart and adds incremental value by imaging scarring and to assess iron level. Despite the existence of MRI units, CMR is identified as a complex test, with poor training and availability in developing countries.
Purpose
To assess the potential impact of a faster CMR protocol at a multicentre level in developing countries; implementing it with an education program, for the assessment cardiomyopathies.
Methods
An international partnership. A rapid CMR protocol for the evaluation of cardiac volumes, function and tissue characterization (Cardiac Iron T2* and LGE for scar) Figure 1a. We deployed the protocol as a multicentre study: Argentina, Peru, India and South Africa accompanied by a program of education. Pre-scan clinical information, scanning data: complications, image quality and post-scan follow-up of participants for the assessment on impact, between 3 to 24 months.
Results
510 scans (4 countries, 6 cities, 12 centres) were performed with the rapid CMR protocol. Contrast studies in 378 (74%). There were no scan-related complications. Quality of the studies was maintained in a high level as an average of 89%. 97% of studies responded referral's question. All patients with contrast CMR scan have had at least one 2D echocardiogram before CMR. Average scan duration was 21±6 mins for contrast studies and 12±3 for non-contrast T2* protocol. The most common underlying diagnoses were non-ischaemic cardiomyopathy in 73% of participants (including cardiac iron level assessment in 26%, HCM in 17%, DCM in 15%), 27% for ischaemic cardiomyopathy and 15% for other pathologies. 4 of the 12 participant centres started to incorporate CMR for the first time. Findings impacted management in 60% of patients, including new diagnosis in 21% of participants. See table 1, figure 1b. For just cardiac iron assessment: 1/3 of participants had iron deposited in the heart with 14% of patients in severe levels.
Conclusions
CMR can be delivered faster and easier. When this abbreviated protocol is enabled with education, it can be implemented in developing countries with existing technology. This protocol shows high quality exam, with an important impact on patient's management.

Abstract
Background Genome-wide association studies (GWASs) have identified several genes associated with obesity. The mechanisms through which these genes affect body weight are not fully characterized. Recent studies suggest that eating behavior (EB) traits could be involved, but only a few EB traits were investigated. Objective This study aimed to investigate whether genetic susceptibility to obesity is mediated by EB traits (cognitive restraint, disinhibition, hunger) and their subscales. We hypothesized that EB traits, and their subscales, partly mediate this association. Design Adult individuals (n = 768) who participated in the Quebec Family Study were included in this cross-sectional study. A genetic risk score (GRS) of obesity was calculated based on the 97 genetic variants recently identified in a GWAS meta-analysis of body mass index (BMI). EB traits and their subscales were assessed with the use of the Three-Factor Eating Questionnaire. Regression analyses with age and sex as covariates were used to investigate the associations between GRS, EB traits, BMI, and WC and whether the association between GRS and obesity is mediated by EB traits, which represents the indirect effect of GRS on obesity. Results The GRS of obesity was positively associated with BMI (β = 0.19 ± 0.04, P < 0.0001) and WC (β = 0.46 ± 0.10, P < 0.0001). Regression analyses also revealed that the association between GRS of obesity and BMI was partly mediated by disinhibition and susceptibility to hunger (βindirect = 0.09 ± 0.03, P = 0.0007, and βindirect = 0.04 ± 0.02, P = 0.02, respectively). Habitual and situational susceptibility to disinhibition (βindirect = 0.08 ± 0.03, P = 0.002 and βindirect = 0.05 ± 0.02, P = 0.003, respectively) as well as internal and external locus of hunger (βindirect = 0.03 ± 0.02, P = 0.03 for both) were also found to mediate the association between GRS of obesity and BMI. The same trends were observed with WC. Conclusions The results of this study indicate that the genetic susceptibility to obesity is partly mediated through undesirable EB traits, which suggests that they could be targeted in obesity treatment and prevention. This trial was registered at clinicaltrials.gov as NCT03355729.

Abstract
This paper summarizes the gaps and challenges related to animal production, health, and food safety as discussed by a panel at the 1st International Symposium of Food Safety (ISFS) in Santiago, Chile, in December 2016. Participating representatives of academia, industry, and government and statements from the audience confirmed that food safety is essential for increasing food security. First, panelists identified the need for a science-based regulatory framework to implement effective regulations. Second, they highlighted the importance of a risk analysis framework to quantify the risk of the potential for antimicrobial resistance associated with the use of antimicrobials, and the need of studies to evaluate foodborne prevention/control strategies. Third, the challenges of filling the gaps between industry and academia were addressed, including examples of successful collaboration, opportunities, and weakness identified by industry. Finally, challenges in animal food production included issues related to changing consumer preferences, animal welfare, the use of antimicrobials, and sustainable animal production. The symposium provided a regional platform to share experiences from the implementation of methods and approaches for food safety. The roundtable successfully explored the future science and technology challenges that are of strategic importance for Chile and the region in animal health and food safety.

Abstract
BACKGROUND Ethnicity is a risk factor for disparate Emergency Department (ED) analgesia. We aimed to explore ethnic variations in the administration of ED analgesia to children with acute appendicitis in Israeli government hospitals. METHODS Children discharged with an International Classification of Disease-Ninth Revision diagnosis of acute appendicitis between 2010 and 2015 were included. The association between patient ethnicity (Jewish, Arab) and analgesia administration (any, opioid) was assessed. Age, gender, triage category, pain score and time of arrival were tested as possible confounders. The effect of patient-nurse ethnic discordance (PNED) was examined. RESULTS Overall, 4714 children with acute appendicitis, 3520 Jewish and 1194 Arab, were cared for in the EDs; 1516 (32.2%) received any analgesia and 368 (7.8%) opioid analgesia. Stratified by pain score, no statistical differences were found in the administration of any or opioid analgesia between Jewish and Arab patients with either severe pain or moderate pain. In multivariate modelling adjusted for pain score and triage category, the rates of any analgesia for Arab and Jewish patients were 31.8% (95% CI, 30.9-32.6) and 36.5% (95% CI, 36.0-36.9), adjusted OR (aOR) = 1.16 (95% CI, 0.98-1.38), respectively. The rates of opioid analgesia for Arab and Jewish patients were 8.5% (95% CI, 8.2-8.9) and 7.9% (95% CI, 7.3-8.7), aOR = 0.77; (95% CI, 0.59-1.22), respectively. Jewish and Arab nurses treated proportionally fewer patients from the opposite ethnicity with any analgesia (p < 0.01). CONCLUSION Emergency Department analgesia was markedly low, and not associated with patient ethnicity. PNED was associated with decreased rates of analgesia. SIGNIFICANCE Emergency Department analgesia for children with acute appendicitis in Israeli government hospitals is markedly low. Patient-provider ethnic discordance may negatively influence the provision of analgesia. Significant efforts should be undertaken in order to increase analgesia provision rates and reduce social inequality.

Abstract
SummaryTotal (or near total) thyroidectomy (TE) followed by radioiodine (131I) ablation (RIA) of residual thyroid tissue is considered to be the ideal treatment for differentiated thyroid carcinoma. However, the actual guideline of the DGN (German Society of Nuclear Medicine) recommends for the so-called papillary micro-carcinoma of the thyroid (PMC) no further therapeutic strategy (no complete TE, no 131I-ablation of the remaining lobe). PMC has been defined as papillary carcinoma measuring 1 cm (T1) in maximal diameter according to the World Health Organization classification system for thyroid tumours (1988). The new WHO-classification (starting in 2003) defines the T1-tumour measuring 2 cm in maximal diameter. The authors demand a new, modern guideline, following the new WHO classification. This includes, that despite the overall excellent prognosis for patients with PMC, the treatment of patients with T1-tumours of the new WHO-classification (including the “old” PMC) should be no different from the treatment of patients with conventional papillary thyroid carcinoma, i.e. complete surgery (TE and central lymph node dissection) followed by RIA of residual thyroid tissue. The authors argue that it is not appropriate to consider the tumour size as the single most important key factor for therapy and prognosis. Even small tumours may have poor prognostic factors, such as lymph node metastasis, multifocality or molecular characteristics (expression of oncogenes).

Abstract
Ubiquitin-dependent sorting of membrane proteins in endosomes directs them to lysosomal degradation. In the case of receptors such as the epidermal growth factor receptor (EGFR), lysosomal degradation is important for the regulation of downstream signalling. Ubiquitinated proteins are recognised in endosomes by the endosomal sorting complexes required for transport (ESCRT) complexes, which sequentially interact with the ubiquitinated cargo. Although the role of each ESCRT complex in sorting is well established, it is not clear how the cargo is passed on from one ESCRT to the next. We here show that flotillin-1 is required for EGFR degradation, and that it interacts with the subunits of ESCRT-0 and -I complexes (hepatocyte growth factor-regulated tyrosine kinase substrate (Hrs) and Tsg101). Flotillin-1 is required for cargo recognition and sorting by ESCRT-0/Hrs and for its interaction with Tsg101. In addition, flotillin-1 is also required for the sorting of human immunodeficiency virus 1 Gag polyprotein, which mimics ESCRT-0 complex during viral assembly. We propose that flotillin-1 functions in cargo transfer between ESCRT-0 and -I complexes.

Abstract
OBJECTIVE To evaluate the effectiveness of a theory-based intervention to reduce the intention to use restrictive dietary behaviors for losing weight among adolescent female athletes involved in aesthetic sports. DESIGN Cluster-randomized controlled trial. SETTING Aesthetic sport teams of adolescent female athletes aged 12-17 years. PARTICIPANTS Two teams (n = 37 athletes) in the intervention group and 3 teams (n = 33) in the comparison group. INTERVENTIONS The 2 groups received nutrition education during 3 weekly 60-minute sessions. The intervention group was further exposed to a theory-based intervention targeting the specific determinant of intention to use restrictive dietary behaviors for losing weight, namely attitude. MAIN OUTCOME MEASURES Difference over time between groups in intention to use restrictive dietary behaviors for losing weight and in nutrition knowledge. ANALYSIS Mixed models for repeated measures. RESULTS The theory-based intervention contributed to maintaining a low intention of using restrictive dietary behaviors for losing weight over time in the intervention group compared with the comparison group (P < .03). Nutrition knowledge score increased equally in both groups. CONCLUSION AND IMPLICATIONS Complementing nutrition education with theory-based behavior change intervention may help maintain a low intention of using restrictive dietary behaviors for losing weight among female high school athletes involved in aesthetic sports.

Abstract
The Earth System Prediction Suite (ESPS) is a collection of flagship U.S. weather and climate models and model components that are being instrumented to conform to interoperability conventions, documented to follow metadata standards, and made available either under open source terms or to credentialed users. The ESPS represents a culmination of efforts to create a common Earth system model architecture, and the advent of increasingly coordinated model development activities in the U.S. ESPS component interfaces are based on the Earth System Modeling Framework (ESMF), community-developed software for building and coupling models, and the National Unified Operational Prediction Capability (NUOPC) Layer, a set of ESMF-based component templates and interoperability conventions. This shared infrastructure simplifies the process of model coupling by guaranteeing that components conform to a set of technical and semantic behaviors. The ESPS encourages distributed, multi-agency development of coupled modeling systems, controlled experimentation and testing, and exploration of novel model configurations, such as those motivated by research involving managed and interactive ensembles. ESPS codes include the Navy Global Environmental Model (NavGEM), HYbrid Coordinate Ocean Model (HYCOM), and Coupled Ocean Atmosphere Mesoscale Prediction System (COAMPS®); the NOAA Environmental Modeling System (NEMS) and the Modular Ocean Model (MOM); the Community Earth System Model (CESM); and the NASA ModelE climate model and GEOS-5 atmospheric general circulation model.

Abstract
BACKGROUND AND PURPOSE Cervical MR imaging has demonstrated a utility for detecting soft tissue injury in nonaccidental trauma. The purpose of this study was to identify the incidence and types of cervical spine injury on MR imaging in nonaccidental trauma and to correlate cervical spine injury with parenchymal injury on brain MR imaging and findings on head CT. MATERIALS AND METHODS A retrospective review of children diagnosed with nonaccidental trauma in a tertiary referral pediatric hospital over 8 years was performed. Inclusion criteria were children younger than 5 years of age, a confirmed diagnosis of nonaccidental trauma, and cervical spine MR imaging within 1 week of presentation. Brain and cervical spine MR imaging, head CT, cervical radiographs, and skeletal surveys were reviewed. RESULTS There were 89 patients included in this study (48 males; mean age, 9.1 months [range, 1-59 months]). Cervical spine injury on MR imaging was found in 61 patients (69%). Ligamentous injury was seen in 60 patients (67%), with interspinous ligaments being most commonly involved. Abnormal capsular fluid (atlanto-occipital and atlantoaxial) was present in 28 patients (32%). Cervical spine injury on MR imaging was significantly associated with parenchymal restricted diffusion on brain MR imaging and parenchymal injury on head CT (P = .0004 and P = .0104, respectively). Children with restricted diffusion on brain MR imaging were 6.22 (point estimate) times more likely to have cervical spine injury on MR imaging. CONCLUSIONS There is a high incidence of cervical spine injury in pediatric nonaccidental trauma. Positive findings may affect management and suggest a traumatic etiology.
