Tympanostomy Tubes Under Local Versus General Anesthesia for Children: A Prospective Long-Term Study.

OBJECTIVES: Tympanostomy tube insertion (TTI) under local anesthesia (LA) is gaining popularity but literature comparing long-term outcomes for children undergoing TTI under LA versus general anesthesia (GA) is limited. This study compares the long-term quality of life (QoL) between LA and GA in children undergoing TTI. Secondary objectives included long-term behavioral changes, parental satisfaction, tube durability, and postoperative complications. METHODS: We prospectively followed children aged under 6 who underwent TTI, under LA or GA, 2 years prior. We assessed QoL using validated scales (OM6, PedsQL), analyzed behavioral changes and parental satisfaction through qualitative scales, and retrieved data on tube durability and non-immediate complications. RESULTS: A total of 84 children (LA = 42; GA = 42) had complete data and a minimum of 1 year of follow-up. Demographic data were similar, except for younger patients in the LA group (1.4 vs. 1.9 years, p = 0.02). LA group exhibited increased fear of health care professionals following TTI (LA: Likert scale 2.1/5, GA: 1.5/5, p = 0.04). Tube retention rate was shorter in the LA group (at 15 months: GA:72%, LA:50%, p = 0.039). Two years post-TTI, there were no differences regarding QoL (OM-6 score; LA: 15.2/100, GA: 21.4/100, p = 0.18, and PedsQL score; LA: 84.3/100, GA: 83.8/100, p = 0.90), parental satisfaction with anesthesia (GA: 4.5/5, LA: 4.6/5, p = 0.56), and postoperative complications (GA: 3/42, LA: 7/42, p = 0.18). CONCLUSIONS: TTI under LA in children is associated with an increased fear of health care professionals and shorter functionality of tympanostomy tubes as compared to GA. No difference was observed in long-term QoL, parental satisfaction, and complications rate. LEVEL OF EVIDENCE: Level 3 Laryngoscope, 2024.

Descriptive and Content Analysis of Questionnaires Used to Assess Evidence-Based Practice Among Dietitians: A Systematic Review.

BACKGROUND: Evidence-based practice (EBP) is described as the integration of the following 3 main dimensions in health professionals' decision making: best currently available research evidence, professional expertise, and patient's values and circumstances. Barriers to EBP at an individual level have been assessed using questionnaires. Knowing which EBP dimensions are actually explored in these questionnaires is essential to promote EBP and its adoption. OBJECTIVE: The aim of this review was to identify and describe questionnaires that have been used among dietitians to evaluate knowledge, skills, attitudes, and/or behaviors related to EBP, and to perform a content analysis of these, drawn on the EBP dimensions explored. METHODS: Questionnaires were identified through a systematic review in MEDLINE, Embase and the Cumulative Index to Nursing and Allied Health Literature (last search was November 2022). Eligibility criteria were studies using, evaluating, or developing questionnaires meant to evaluate knowledge, skills, attitudes, and/or behaviors related to EBP among dietitians. The content analysis was conducted to identify the EBP dimensions explored (ie, research evidence, professional expertise, and/or patient's values and circumstances). Questionnaire items were categorized as follows: 1 sole EBP dimension, a combination of dimensions, or no identifiable dimension. RESULTS: Thirty reports (25 studies) were included. The analysis of the 847 items extracted from the 25 questionnaires used showed that the main EBP dimension explored was the integration of research evidence into decision making, found in 75% of items, solely or in combination with another dimension. Professional expertise was explored in 18% of the items, patient's values and circumstances were found in 3%, and the combination of these 3 dimensions was found in <1%. CONCLUSIONS: The important imbalance of explored EBP dimensions in the questionnaires used may lead to a partial and misleading evaluation that prevents efficient strategies to foster EBP. There is an important need to develop more integrative and accurate evaluations of EBP targeting dietitians to promote and develop high-quality dietetics practice.

Comparison of Tympanostomy Tubes Under Local Anesthesia Versus General Anesthesia for Children.

OBJECTIVE: Tympanostomy tube insertion (TTI) is typically accomplished under general anesthesia (GA) in the operating room. We aimed to compare pain between GA and local anesthesia (LA) in surgically naïve children undergoing TTI. Secondary objectives examined patient's quality of life (QoL) and parent's satisfaction. STUDY DESIGN: Prospective single-center study. SETTING: Tertiary pediatric academic center. METHODS: Consecutive children who underwent TTI under GA were compared to patients under LA. Pain standardized observational pain scales (Face, Legs, Activity, Cry, Consolability Scale [FLACC], Children's hospital of Eastern Ontario Pain Scale [CHEOPS]) were completed pre-procedure, during the first tympanostomy and second tympanostomy, and post-procedure, as well as 1 week postoperatively. General health-related QoL (PedsQL) and QoL specific to otitis media (OM-6) were measured before insertion and 1 month postoperatively. Parental satisfaction was also evaluated using a qualitative scale. RESULTS: LA group had statistically significant higher pain levels at the beginning (7.3 vs. 0), during the first tympanostomy (7.8 vs. 0), during the second tympanostomy (7.7 vs. 0), and at end of the procedure (6.9 vs. 0) with the FLACC scale (all p < 0.01). Results were similar with the CHEOPS scale. No pain was noted 1 week after surgery in either group. Both groups had similar improvement in their QoL (p > 0.05). Minor complication occurred at a similar rate (p > 0.05). Parents were equally satisfied with their choice of anesthesia in both groups when initially questioned after the procedure (p > 0.05). CONCLUSIONS: Children experienced significantly less pain under GA than LA. If LA is to be used, pain and distress-reducing strategies are critical. Shared decision-making with families is essential.

Beliefs about Healthy Sleep Habits in Adults with Diabetes Compared to Adults without Diabetes: A Reasoned Action Approach Elicitation Study.

Objective Sleep is part of a healthy lifestyle and in adults with diabetes, inadequate sleep is associated with risks of developing complications. The objective was to compare beliefs about healthy sleep habits (HSHs) in adults with versus without diabetes based on the Reasoned Action Approach. Methods A total of 56 adults with and 98 without diabetes answered open-ended questions regarding their beliefs about: avoiding screen use in bed; having a regular sleep schedule; or avoiding caffeine, alcohol, and cigarettes before bedtime. A qualitative content analysis was used to identify the most important beliefs, similarities, and differences between both groups. Results Both groups reported that adopting HSHs could improve sleep. Having a regular sleep schedule was perceived to facilitate diabetes management in adults with diabetes. Negative consequences specific to adopting each HSH were identified in both groups. Adopting HSHs was associated with mainly negative emotions (e.g., stress, anxiety, fear) in both groups. Avoiding screen use in bed was associated with anxiety of not knowing blood glucose levels at night in adults with diabetes. Partners, parents, and friends were considered the most important individuals who would approve of adopting HSHs, but they were often perceived as unlikely to adopt HSHs themselves in both groups. Adults with diabetes perceived more barriers to adopting HSHs. Facilitating factors for both groups included removing triggers of unhealthy sleep habits, behavior substitution, using reminders, time management, and social support. Discussion These beliefs can guide the development of behavioral sleep interventions, including interventions specifically for adults with diabetes.

E-learning to teach medical students about acute otitis media: A randomized controlled trial.

OBJECTIVES: Acute otitis media (AOM) is extremely prevalent among children but its diagnosis remains challenging. Our primary objective was to measure the impact of an e-learning module on medical students' accuracy in diagnosing paediatric AOM. METHODS: This randomized controlled trial was performed at a single tertiary care paediatric emergency department (ED). Medical students on their paediatric rotation were randomized to a locally developed e-learning module or a small-group lecture on AOM. They then had to examine at least 10 ears of patients at risk for AOM. The primary outcome was diagnostic accuracy and secondary outcomes included knowledge test scores and learning modality preference. RESULTS: Between May 2017 and September 2018, 201 medical students were randomized. Eighty-three evaluated at least 10 ears and were included in the primary analysis. Diagnostic accuracies (76.5% for the e-learning group versus 76.4% for the lecture group, difference of 0.1%; 95%CI: -6.2 to 6.4%) and post-test scores (difference of 0.5/20 points; 95%CI: -0.8 to 1.2/20 points) were similar between the groups. Sixty-two per cent of participants preferred the e-learning module to the lecture, while 15% had no preference. CONCLUSIONS: Diagnostic accuracy for AOM was similar between students exposed to an e-learning module or a small-group lecture. E-learning was the preferred learning modality.

A Rapid Review of Territorialized Food Systems and Their Impacts on Human Health, Food Security, and the Environment.

The global food system is facing multiple problems, including rising food insecurity, degrading environments, and an increased incidence of diet-related chronic diseases. International organizations are thus calling for a transition toward territorialized food systems to alleviate some of these challenges. Yet, limited evidence supporting the benefits of territorialized food systems is available. Our objective was to summarize the current body of literature on territorialized food systems and their impacts on human health, food security, and the environment using a rapid review methodology. Articles were retrieved from three databases and analyzed using keywords and inclusion criteria corresponding to territorialized food systems, environment, human health, and food security. Six relevant publications were identified. While this limited evidence suggests that territorialized food systems may have positive effects on all three dimensions, data are not consistent across publications. For example, territorialized food systems may contribute to improved diet quality, provide agroecosystem services, and contribute to food security. However, food produced within these food systems may have a higher carbon footprint and be less available than industrially produced food. This rapid review also highlights the siloed nature of the current research on territorialized food systems and emphasizes the need for more holistic and interdisciplinary research.

Changes in diet quality and food security among adults during the COVID-19-related early lockdown: results from NutriQuébec.

BACKGROUND: The impact that the coronavirus disease 2019 (COVID-19)-related early lockdown has had on dietary habits of the population and on food insecurity is unknown. OBJECTIVE: The aim of this study was to document the change in diet quality and in food insecurity observed during the COVID-19-related early lockdown. We hypothesized that the lockdown was associated with a deterioration in overall diet quality and an increase in food insecurity. METHODS: Data are from a COVID-19 subsample of NutriQuébec, a web-based cohort destined to study temporal changes in dietary habits among adults in Quebec, Canada. Participants completed questionnaires before (between June 2019 and February 2020) and during (April to May 2020) early lockdown, including a validated web-based 24-h recall (n = 853) and a questionnaire on food security (n = 922). Primary study outcomes were temporal changes in diet quality measured by the Healthy Eating Index (HEI)-2015 and in the prevalence of food insecurity. RESULTS: There was a small increase in the HEI-2015 during the COVID-19 early lockdown compared with baseline (+1.1 points; 95% CI: 0.6, 1.5), mostly due to small improvements in the intakes of whole grains, greens and beans, refined grains, total vegetables, total dairy, seafood and plant proteins, added sugar, and total protein subscores of the HEI-2015. Exploratory analyses suggested that individuals aged 18-29 y (+3.6 points; 95% CI: 2.4, 4.7), participants with lower education (+1.9 points; 95% CI: 1.3, 2.6), or with obesity (+3.8 points; 95% CI: 2.7, 4.8) showed particularly important increases in the HEI-2015. The prevalence of food insecurity was reduced from 3.8% at baseline to 1.0% during the early lockdown (prevalence ratio = 0.27; 95% CI: 0.08, 0.94). CONCLUSIONS: Contrary to our hypotheses, diet quality has slightly improved and prevalence of food insecurity was reduced in this sample of adults from Quebec during the COVID-19-related early lockdown. These results may be generalizable only to relatively healthy populations.

Environmental Scan on Canadian Interactive Knowledge Translation Tools to Prevent Diabetes Complications in Patients With Diabetes.

In this study, we identify existing interactive knowledge translation tools that could help patients and health-care professionals to prevent diabetes complications in the Canadian context. We conducted an environmental scan in collaboration with researchers and 4 patient partners across Canada. We conducted searches among the research team members, their networks and Twitter, and through searches in databases and Google. To be included, interactive knowledge translation tools had to meet the following criteria: used to prevent diabetes complications; used in a real-life setting; used any instructional method or material; had relevance in the Canadian context, written in English or French; developed and/or published by experts in diabetes complications or by a recognized organization; created in 2013 or after; and accessibility online or on paper. Two reviewers independently screened each record for selection and extracted the following data: authorship, objective(s), patients' characteristics, type of diabetes complications targeted, type of knowledge users targeted and tool characteristics. We used simple descriptive statistics to summarize our results. Thirty-one of the 1,700 potentially eligible interactive knowledge translation tools were included in the scan. Tool formats included personal notebook, interactive case study, risk assessment tool, clinical pathway, decision support tool, knowledge quiz and checklist. Diabetes complications targeted by the tools included foot-related neuropathy, cardiovascular diseases, mental disorders and distress and any complications related to diabetes and kidney disease. Our results inform Canadian stakeholders interested in the prevention of diabetes complications to avoid unnecessary duplication, identify gaps in knowledge and support implementation of these tools in clinical and patients' decision-making.

Factors influencing engagement and dietary behaviour change of mothers and their children in a blog-delivered healthy eating intervention: a process evaluation of a randomised controlled trial.

OBJECTIVE: A randomised controlled trial found no evidence of an impact of a blog written by a registered dietitian (RD) on vegetables and fruit and milk and alternatives (e.g. soya-based beverages, yogurt and cheese) consumption - two food groups included in the 2007 version of the Canadian Food Guide - in mothers and their children compared with a control condition. To investigate these null findings, the current study explored participants' perceptions of engagement with the blog and its influence on their dietary behaviours. DESIGN: Mixed methods process evaluation using a post-intervention satisfaction questionnaire and a content analysis of mothers' comments on the blog (n 213 comments). SETTING: French-speaking adult mothers living in Quebec City, Quebec, Canada (n 26; response rate = 61·9 % of the total sample randomised to exposure to the blog). RESULTS: Most mothers (n 20/26; 76·9 %) perceived the blog useful to improve their dietary habits - with the most appreciated blog features being nutritional information and healthy recipes and interactions with fellow participants and the RD. Mothers reported several facilitators (e.g. meal planning and involving children in household food activities) and few barriers (e.g. lack of time and children's food preferences) to maternal and child consumption of vegetables and fruit and milk and alternatives. Lack of time was the principal reported barrier affecting blog engagement. CONCLUSIONS: The findings from the current study suggest that blogs written by an RD may be an acceptable format of intervention delivery among mothers, but may not alleviate all the barriers to healthy eating and engagement in a dietary intervention.

NutriQuébec: a unique web-based prospective cohort study to monitor the population's eating and other lifestyle behaviours in the province of Québec.

INTRODUCTION: The epidemic of non-communicable diseases including cardiovascular diseases and type 2 diabetes is attributable in large part to unhealthy eating and physical inactivity. In the fall of 2016, the Québec government launched its first-ever Government Health Prevention Policy (Politique gouvernementale de prévention en santé (PGPS)) to influence factors that lead to improved health status and quality of life as well as reduced social inequalities in health in the population of Québec. NutriQuébec is a web-based prospective open cohort study whose primary aim is to provide essential data for the evaluation of the PGPS on the Québec population's eating and other lifestyle behaviours over time. METHODS AND ANALYSIS: Over a first phase of 3 years, NutriQuébec will enrol 20 000 adults living in the province of Québec in Canada through a multimedia campaign designed to reach different segments of the population, including subgroups with lower socioeconomic status. Participants will be invited to complete on a web platform nine core questionnaires on a yearly basis. Questionnaires will assess several dimensions related to lifestyle, including eating and physical activity behaviours, as well as a large number of personal characteristics and global health status. Temporal trends in eating and lifestyle behaviours will be analysed in relation to the implementation of the PGPS to provide essential data for its evaluation at a population level. Data analyses will use sociodemographic weights to adjust responses of participants to achieve, so far as is possible, representativeness of the adult Québec population. ETHICS AND DISSEMINATION: Université Laval Research Ethics Board approved the NutriQuébec project. Data analysis, presentations in conferences and publication of manuscripts are scheduled to start in 2020. TRIAL REGISTRATION NUMBER: NCT04140071.

Recruitment and retention of mothers of preschoolers and school-aged children in a social media-delivered healthy eating intervention: lessons learned from a randomized controlled trial.

BACKGROUND: Social media represent cost-effective platforms to advance the dissemination and uptake of health research to improve population health. However, there is limited evidence available to support researchers overcome methodological challenges related to recruitment and retention of participants in studies using social media for delivering behavior change interventions. This study aims to describe the recruitment and the retention strategies used in a randomized controlled trial (RCT) that evaluated a blog-delivered healthy eating intervention among mothers of preschoolers and school-aged children. METHODS: Eighty-four adult mothers of children aged between two and 12 years old living in Quebec City, Quebec, Canada, were recruited between October 2015 and February 2017 using traditional methods (e.g. institutional email lists, flyers, newspapers, and word of mouth) and Facebook advertisements. Retention rates were calculated at the end of the 6-month intervention and at a 12-month follow-up assessment. Sociodemographic characteristics, Internet use behaviors and retention rates of mothers recruited through traditional methods and Facebook were compared using Wilcoxon-Mann-Whitney tests and Fisher exact tests. RESULTS: Of the 196 mothers who responded to the recruitment call, 87 (44.4%) were eligible and 84 (42.9%) were randomized to the trial, representing a recruitment success of 76.4% (84/110) from the planned sample size target. Among those, a minority (3.6%) were recruited using Facebook. Those mothers presented similar sociodemographic characteristics to those recruited using traditional methods. Retention rates were 73.8% and 66.7% at 6 and 12 months, respectively, with similar rates between mothers recruited using Facebook and traditional methods. Various challenges associated with population retention were highlighted with lack of time being mothers' main reason for withdrawing from the study. CONCLUSIONS: The methodological challenges experienced during the conduct of the blog-delivered healthy eating intervention allowed to draw upon several lessons regarding the recruitment process and the retention of mothers of preschoolers and school-aged children to inform future social media-delivered research. Recommendations for future research include exploring mothers' perceptions and preferences to tailor social media recruitment, ensure that interventions are delivered to them using social media platforms that are already integrated into their routine, and are providing remote outcome assessments to increase participant retention.

A cross-sectional survey examining motivation and beliefs to participating in a web-based prospective cohort study on nutrition and health among individuals with a low socioeconomic status.

BACKGROUND: Prospective cohort studies may support public health efforts in reducing health inequalities. However, individuals with a low socioeconomic status (SES) are generally underrepresented in health research. This study aimed to examine the intention and determinants of intention of individuals with a low SES towards participation in a Web-based prospective project on nutrition and health (NutriQuébec) in order to develop recruitment and retention strategies. METHODS: A cross-sectional survey based on the Theory of planned behaviour was conducted in the Province of Québec, Canada. Low SES individuals (high school or less and annual household income < $55,000 CAN) were recruited through a Web panel of a polling firm to assess intention, attitude, subjective norm and perceived behavioural control (PBC) towards participation in the NutriQuébec project. Linear regression and logistic regression analyses were conducted. RESULTS: Mean age of respondents (184 women, 141 men) was 57.6 y (SD = 13.6). Attitude (ß = 0.54, 95%CI: 0.41-0.68) and PBC (ß = 0.50, 95%CI: 0.37-0.63) were significantly associated with intention. Participants who agreed that participating in the study would contribute to an improvement in 1) collective health (odds ratio [OR] = 2.15, 95%CI: 1.27-3.64) and in 2) one's lifestyle habits (OR = 1.70, 95%CI: 1.04-2.78) were more likely to express positive intention compared to participants who did not agree with these statements. Participants who agreed to participate in the study even 1) in the absence of a financial incentive (OR = 1.43, 95%CI: 1.04-1.99) and even 2) if the completion of questionnaires took up to two hours (OR = 1.78, 95%CI: 1.27-2.48) were also more likely to express high intention. Receiving a personalized brief health assessment (OR = 1.61, 95%CI: 1.13-2.30) and the use of simple questions in the questionnaires (OR = 1.54, 95%CI: 1.05-2.25) were facilitating factors associated with high intention. Participants believing that participation would be too time-consuming were less likely to have positive intention (OR = 0.57, 95%CI: 0.43-0.75). CONCLUSIONS: The development of a positive attitude and a high PBC towards participation in the NutriQuébec project will be necessary to obtain representative data of low SES adults.

Long-term effects of a healthy eating blog in mothers and children.

In the context of low consumption of vegetables and fruits and milk and alternatives among Canadian mothers and children, novel strategies are needed to improve maternal and child nutrition. This study evaluated the long-term effects of an evidence-informed healthy eating blog on dietary intakes and food-related behaviours of mothers and their child. The study presents a secondary outcome analysis of a randomised controlled trial in which 84 mothers (mean age of 37.6 ± 6.7 years) of 2- to 12-year-old children living in Quebec City, Canada, were randomly assigned to a dietary intervention delivered through a healthy eating blog written by a registered dietitian (RD; n = 42) or a control group (n = 42) during a period of 6 months. Dietary intakes, maternal eating behaviours, food parenting practices, and body weight were measured at baseline, 3 months, at the end of the intervention (6 months), and 6-month post-intervention (12 months). Differences between groups were assessed with mixed linear models. Globally, this study found no evidence of long-term differences in mean dietary intakes in mothers exposed to the blog and their children as well as other food-related outcomes and body weight compared with the control condition. Potential predictors of adherence to dietary recommendations in mothers and children (e.g., involvement of children in household food activities) were identified. In conclusion, a healthy eating blog written by an RD did not result in evidence of any long-term differences in dietary intakes and food-related behaviours in mothers and their children compared with the control condition.

Effects of an Evidence-Informed Healthy Eating Blog on Dietary Intakes and Food-Related Behaviors of Mothers of Preschool- and School-Aged Children: A Randomized Controlled Trial.

BACKGROUND: Although social media such as blogs are still considered innovative communication technologies, some registered dietitians (RDs) are using them to promote healthy eating; however, evidence regarding the effects of healthy eating blogs on users' diet is lacking. OBJECTIVE: This study evaluated the effects of an evidence-informed healthy eating blog written by an RD on dietary intakes, with a focus on vegetables and fruit and milk and alternatives consumption, and food-related behaviors of Canadian mothers. DESIGN: This study was a parallel, randomized, controlled trial. PARTICIPANTS/SETTING: Data were collected from 84 French-speaking adult mothers of children aged between 2 and 12 years living in Quebec City, Quebec, Canada, who were recruited between October 2015 and February 2017 using institutional e-mail lists, flyers, newspapers, social media advertisements, and word of mouth. INTERVENTION: The intervention was exclusively delivered through an evidence-informed healthy eating blog-integrating theory-based intervention methods to improve diet quality by increasing vegetables and fruit and milk and alternatives consumption in mothers-for 6 months at a dose of one new post written by an RD each week. Mothers could engage with the RD and fellow participants by posting comments on the blog. MAIN OUTCOME MEASURES: Main outcomes were daily intakes of vegetables and fruit and milk and alternatives. Outcome assessments were performed at baseline, 3 months, and at the end of the 6-month intervention. STATISTICAL ANALYSIS: Differences between the groups were examined using mixed linear models. RESULTS: At 6 months, no significant difference was observed between groups for intakes of vegetables and fruit (P=0.923), milk and alternatives (P=0.271), or food-related behaviors and body weight (P=0.180). CONCLUSIONS: A healthy eating blog, at a dose of 1 post per week, had no effects on dietary intakes, food-related behaviors, and body weight of mothers after 6 months. Methodologic issues are discussed to inform future health behavior research using blogs to promote healthy eating.

Beliefs Related to Participation in a Large Web-Based Prospective Survey on Diet and Health Among Individuals With a Low Socioeconomic Status: Qualitative Study.

BACKGROUND: NutriQuébec is a Web-based prospective study on the relationship between diet and health as well as the impact of food-related health policies in the adult population of Québec, Canada. Recruitment and retention of individuals with a low socioeconomic status (SES) in such a study are known to be challenging, yet critical for achieving representativeness of the entire population. OBJECTIVE: This study aimed to identify the behavioral, normative, and control beliefs of individuals with a low SES regarding participation in the NutriQuébec project and to identify their preferences regarding recruitment methods. METHODS: A total of four focus groups were conducted in community centers located in low-income areas of Québec City, Canada. On the basis of the theory of planned behavior, participants' beliefs associated with attitude, subjective norm, and perceived behavioral control regarding hypothetical participation in the NutriQuébec project were identified. Focus groups were recorded, transcribed, and coded by two analysts. RESULTS: Participants (16 men and 12 women) were aged between 28 and 72 years, and a majority of the participants had an annual household income of Can $19,999 or less. The main perceived advantages of participating in the NutriQuébec project were contributing to improved collective health and supporting research. The only disadvantage identified was the risk of having to fill out too many questionnaires. Participants could not, in general, identify persons from their entourage who would approve or disapprove their participation in the study. The main facilitators identified were obtaining a brief health assessment and the ability to complete questionnaires in a way that is not Web-based. The main barrier was the lack of internet access. The preferred means of recruitment were through social media, television, and community centers. CONCLUSIONS: These results provide insightful information regarding the best methods and messages to use in order to recruit and retain individuals with a low SES in a population-based prospective study on lifestyle and health on the internet.

Gastrointestinal hemodynamic changes during therapeutic hypothermia and after rewarming in neonatal hypoxic-Ischemic encephalopathy.

BACKGROUND: Hypoxic-ischemic encephalopathy (HIE) is associated with disturbances in visceral blood flow velocities. Therapeutic Hypothermia (TH) is a standard of care; however, its impact on gastrointestinal blood flow in infants with HIE is unknown. The objective of this study was to assess gastrointestinal (GI) blood flow and left ventricle output (LVO) in infants with hypoxic-ischemic encephalopathy during whole body TH and after rewarming. METHODS: Serial echocardiography and Doppler evaluation of intestinal blood flow (celiac (CA) and superior mesenteric (SMA) arteries) were prospectively performed in a cohort of 20 newborn infants with HIE at 4 time points during hypothermia and after rewarming. Demographic, clinical and biochemical data were collected and analyzed for their relevance. RESULTS: Median gestational age and birth weight was 40 weeks (37-41) and 3410 g (2190-4950) respectively. Celiac and mesenteric artery flow remained low during hypothermia and rose significantly after rewarming [peak systolic velocity in CA (0.63 m/s to 0.77 m/s, p = 0.004) and SMA (0.43 m/s to 0.55 m/s, p = 0.001)]. This increase was temporally associated with increased left ventricular output (106 ml/kg/min to 149 ml/kg/min, p < 0.0001). Median age to reach 25% of the feeds was 5 days (1-7 days). All patients survived. CONCLUSIONS: CA and SMA blood flow velocity and LVO did not vary during hypothermia but rose after rewarming. This may suggest protective effect of therapeutic hypothermia on gastrointestinal system. The association of these physiological changes with neonatal outcome needs further assessment.

Characteristics of children with refractory acute otitis media treated at the pediatric emergency department.

INTRODUCTION: Refractory acute otitis media (rAOM) is defined as the persistence of signs and symptoms of AOM for more than 48 to 72 hours after the initiation of antibiotic treatment. These patients are often referred to the pediatric emergency department (PED). We sought to study rAOM cases referred to our PED, and to evaluate their clinical characteristics and response to our local management guidelines. METHODS: A retrospective chart review of all children treated for rAOM between 1/2012-3/2014 was performed. Data recorded included demographics, clinical presentation, antibiotic treatments, need for surgery, and culture results. RESULTS: A total of 255 patients were included with a mean age of 19 months. Prior to admission, all the children had received at least one course of antibiotics. Amoxicillin was the most common first-line antibiotic prescribed while amoxicillin-clavulanic acid was the most common second and third-line antibiotic given. Intravenous ceftriaxone was the treatment administered at the PED. Myringotomy and pressure equalizing tube (PET) insertion were required in 60% of cases. Middle ear cultures (55 ears) were positive for Streptococcus pneumoniae in two, and Moraxella catarrhalis in only one culture. There were no differences between the mean age of children who had PET insertion and those who did not with regards to fever, rhinorrhea, and preschool or school attendance. Children presenting with otorrhea were less likely to undergo surgery (P = 0.013). CONCLUSIONS: This is the first study evaluating the established local practice guideline with regards to clinical characteristics and need for surgical management. We showed that myringotomy and PET insertion due to antibiotic failure is commonly performed for cases of rAOM. The majority of the middle ear cultures were sterile.

Comparing Interviewer-Administered and Web-Based Food Frequency Questionnaires to Predict Energy Requirements in Adults.

Traditional food frequency questionnaires (FFQs) are influenced by systematic error, but web-based FFQ (WEB-FFQs) may mitigate this source of error. The objective of this study was to compare the accuracy of interview-based and web-based FFQs to assess energy requirements (mERs). The mER was measured in a series of controlled feeding trials in which participants daily received all foods and caloric drinks to maintain stable body weight over 4 to 6 weeks. FFQs assessing dietary intakes and hence mean energy intake were either interviewer-administered by a registered dietitian (IA-FFQ, n = 127; control method) or self-administered using a web-based platform (WEB-FFQ, n = 200; test method), on a single occasion. Comparison between self-reported energy intake and mER revealed significant under-reporting with the IA-FFQ (-9.5%; 95% CI, -12.7 to -6.1) and with the WEB-FFQ (-11.0%; 95% CI, -15.4 to -6.4), but to a similar extent between FFQs (p = 0.62). However, a greater proportion of individuals were considered as accurate reporters of energy intake using the IA-FFQ compared with the WEB-FFQ (67.7% vs. 48.0%, respectively), while the prevalence of over-reporting was lower with the IA-FFQ than with the WEB-FFQ (6.3% vs. 17.5%, respectively). These results suggest less accurate prediction of true energy intake by a self-administered WEB-FFQ than with an IA-FFQ.

Is eating pleasure compatible with healthy eating? A qualitative study on Quebecers' perceptions.

Given that traditional interventions promoting the adoption of a healthy diet are having limited impacts on the population's food choices and eating behaviours, researchers and health practitioners could explore alternative strategies such as the use of eating pleasure to promote healthy eating. To inform future interventions using this approach, this study aimed to explore how a sample of Quebecers perceives and defines eating pleasure and healthy eating. Specific objectives were to verify what commonalities can be found between their definitions of eating pleasure and healthy eating, and what differences can be observed in their answers based on their sex and body mass index (BMI). Twelve focus groups were conducted in Quebec City, Canada, among women and men with a normal weight and with obesity (n = 92). Verbatim transcripts were double-coded using NVivo10. Participants mostly defined eating pleasure through food characteristics related to sensory qualities and psychosocial contexts. In contrast, they mostly mentioned food characteristics related to nutritional quality and ways to regulate eating behaviours to define healthy eating. Most salient perceptions were similar among subgroups based on sex or BMI. Results showed that in participants' perceptions, the concepts of eating pleasure and healthy eating were different, but appeared to be mostly compatible, which makes the integration of eating pleasure a promising avenue for interventions promoting healthy eating.

Diagnosing acute otitis media using a smartphone otoscope; a randomized controlled trial.

BACKGROUND: The CellScope Oto® is a smartphone otoscope attachment allowing physicians to share diagnostic-quality images of the ears. Our primary objective was to evaluate the residents' accuracy in diagnosing acute otitis media in children using the CellScope Oto® attachment compared to traditional otoscope. METHODS: A randomized crossover controlled trial was performed at a single, tertiary care, pediatric emergency department. Participants were a convenience sample of preschool children, consulting for fever and respiratory symptoms. All children were evaluated by two residents randomized to use the CellScope Oto® smartphone device or a traditional otoscope. The primary outcome was the diagnostic accuracy of residents in ear evaluation compared to pediatric otolaryngologist's using binocular microscopy. Secondary outcomes included the need for a second ear exam by the treating physician and parental preference. RESULTS: Between August 2015 and June 2016, 90 residents examined 100 patients. Six patients were excluded, leaving 94 children evaluated twice. Diagnostic accuracies were 0.69 (95% CI: 0.52 to 0.75) for the residents using a traditional otoscope and 0.74 (95% CI: 0.68 to 0.80) for those using the CellScope Oto® for an absolute difference of 0.06 (95% CI: -0.03 to 0.15). The emergency physicians reported no need for a control exam in 49/91 (54%) situations. Finally, 44 (47%) families preferred the CellScope Oto®, 26 (28%) the traditional otoscope and 23 (25%) had no preference. CONCLUSIONS: Residents using the CellScope Oto® had accuracies as good as those using the traditional otoscope to evaluate the ears of young children at risk of acute otitis media. www.clinicaltrials.gov: Identifier NCT02521597.
