The association of age and adverse events of PEG-asparaginase in a pediatric tertiary care hospital; a retrospective review.

BACKGROUND: Pediatric patients have a better survival rate for lymphoid malignancies than adolescents and young adult patients (AYA) and current evidence suggests that asparaginase plays a role in improved response to treatment. This study aimed to evaluate if increasing age as a continuous variable demonstrated increasing toxicities to PEG-asparaginase (PEG-ASP) for those patients treated at a tertiary care pediatric hospital. METHODS: A retrospective chart review from 2007 to 2017 was conducted in the pediatric population at the Children's Hospital of Eastern Ontario (CHEO). Patients having received PEG-ASP were included. Event incidence and risk related to age at diagnosis were assessed through parameter estimates and Wald chi-square analysis. RESULTS: In total, 75 adverse events were observed: 34/186 (18.3%) experienced allergic reactions, 8/186 (4.3%) pancreatitis, 31/186 (16.7%) thrombosis, and 2/186 (1.1%) hemorrhage. One hundred and eighty two patients had complete information for inclusion in our model. A correlation between age at diagnosis and higher risk of allergic reaction (p < .001) and pancreatitis (p < .035) was observed. CONCLUSION: Allergic reaction and pancreatitis following administration of PEG-ASP have a higher risk of occurrence as age of diagnosis increases up to 18 years of age. This includes the lower limit of traditionally defined AYA population of 15-39 and warrants precaution as PEG-ASP is included in older populations treatment regimens at pediatric centers.

An examination of cannabis-related information typically asked by consumers at retail cannabis locations: A Canadian survey of budtenders and managers.

Background: Since cannabis has been legalized in Canada for medicinal and recreational use, there has been an increased demand on pharmacists for cannabis counselling. The aim of the study was to examine typical questions posed by consumers to managers and budtenders working at licensed recreational cannabis stores in Canada and to assess how often consumers seek unlicensed medical advice to treat various conditions using cannabis. Methods: An online survey was synthesized, consisting of 22 questions capturing demographics and Likert scale responses to survey questions, and was distributed online across Canada from January to June 2021. Results: There were 211 survey respondents: 91 budtenders and 120 managers. A total of 87.7% (n = 185) of respondents indicated that they receive questions related to cannabis use for medical purposes and/or perceived medical benefit, with the same number indicating that they have been told by a customer that their physician sent them to obtain a cannabis-containing product for medical purposes. The most common cannabis component asked about in an average day was THC (42% of responses). Conclusion: An alarming proportion of budtenders and managers in Canada report that they are fielding medical cannabis questions. This situation has the potential to put individuals at risk for drug-drug interactions and drug-disease interactions and to increase unnecessary hospitalizations due to adverse effects.

Health literacy for children and families.

The relationship between reading ability and health, known as health literacy, broadly reflects the skills and competencies required to operate within the healthcare environment. It is only recently that we have seen attempts to conceptualize health literacy in the context of medication use by using terms such as medication literacy. Health literacy changes over one's lifetime and is dependent on factors such as numeracy, education, income, gender and country. Low health literacy and low medication literacy have been identified as significant risk factors for poor health outcomes of adults and children. With an evaluation of common tools used to assess health literacy and medication literacy, the aim of this review is to describe the shared responsibility between patients and healthcare providers for the communication of health and medication information. Key strategies and interventions to improve two-way communication between patients and healthcare providers are highlighted, with a focus on how health literacy can impact child health outcomes.

Two-month administration of methylphenidate improves olfactory sensitivity and suppresses appetite in individuals with obesity.

Olfaction contributes to feeding behaviour and is modulated by changes in dopamine levels. Methylphenidate (MPH) increases brain dopamine levels and has been shown to reduce appetite and promote weight loss in patients with attention deficit hyperactivity disorder. The objectives of this study were to test the effect of MPH on olfaction, appetite, energy intake, and body weight (BW) on individuals with obesity. In a randomized, double-blind study, 12 participants (age 28.9 ± 6.7 years) with a body mass index (BMI) of 36.1 ± 4.5 kg/m2 were assigned to MPH (0.5 mg/kg) (n = 5) or placebo (n = 7) twice daily for 2 months. Appetite (visual analog scale), odour threshold (Sniffin' Sticks®), energy intake (food menu), and BW (DEXA scan) were measured at day 1 and day 60. MPH intake significantly increased odour threshold scores (6.3 ± 1.4 vs. 9.4 ± 2.1 and 7.9 ± 2.3 vs. 7.8 ± 1.9, respectively; p = 0.029) versus placebo. There was a significantly greater suppression of appetite sensations (desire to eat (p = 0.001), hunger (p = 0.008), prospective food consumption (p = 0.003)) and an increase in fullness (p = 0.028) over time in the MPH versus placebo. MPH suppressed appetite and improved olfactory sensitivity in individuals with obesity. These data provide novel findings on the favourable effects of MPH on appetite and weight regulation in individuals living with obesity.

Pictograms for safer medication handling by health care workers: a validation study in nursing students in Poland.

BACKGROUND AND OBJECTIVE: Medication use often causes errors that are dangerous to the health of patients. Previous studies indicate that the use of pharmaceutical pictograms can effectively reduce medication errors. The purpose of this study was to determine the comprehensibility, representativeness, and recall rate of nine medication safety pictograms in a sample of nursing students in Poland in order to validate these images. METHODS: A pictogram validation study was conducted in two phases among nursing students at the Hipolit Cegielski State University of Applied Sciences, Gniezno, Poland. All experimental protocols were approved by the Children's Hospital of Eastern Ontario Research Ethics Board (REB Protocol No: 19/122X). All methods were carried out in accordance with relevant guidelines and regulations. In phase 1, the participants' first exposure to the pictograms, the students were asked to guess the meaning of the pictograms without any additional information in order to assess the pictograms' comprehensibility. To be considered valid, according to ISO standards, the pictograms had to be correctly understood by at least 66.7% of participants. After testing all pictograms, students were given explanations and meanings of the pictograms and asked to rate the representativeness of pictograms. To do so, participants were asked to select a number on a seven-point Likert-style scale to indicate the perceived strength of the relationship between the pictogram and its intended meaning for each pictogram. To be considered valid, a pictogram had to be rated at least five on this scale by at least 66.7% of participants. Phase 2 took place four weeks later, during which recall of the intended meaning and representativeness were assessed following the same procedure. RESULTS: A total of 66 third-year nursing students participated in both phases. In phase 1, of the nine pictograms, six met ISO requirements for comprehensibility and seven met ISO requirements for representativeness. In phase 2, all nine pictograms were correctly understood and rated at least 5 by at least 66.7% of participants. Therefore, all nine pictograms are considered valid. CONCLUSIONS: The nine medication safety pictograms can be deployed, but must be combined with training and a written hazard statement to improve comprehension.

Patient satisfaction with pharmacist-administered COVID-19 vaccines in Poland: a survey study in the vaccination centres context.

BACKGROUND: Since 2021, pharmacists in Poland have been authorised to administer vaccinations against COVID-19, which is of particular significance in the efforts towards preventing the spread of the pandemic. The primary objective of this study was to evaluate the patients' satisfaction with delivering vaccinations through national vaccination centres. METHODS: This study was conducted in 2021. The research tool was an anonymous questionnaire distributed to patients after vaccination. The questionnaire was developed specifically for the purpose of the study. Ultimately, 628 patients participated in this study. RESULTS: Nearly 97% of the respondents agreed that the administration of vaccinations by pharmacists had been convenient, and pharmacists possessed the relevant skills to provide this service. Almost 90% of the respondents expressed their readiness to be vaccinated by pharmacists again. Nearly all the respondents indicated that pharmacists should also provide other vaccinations. CONCLUSIONS: Patients in Poland have a positive attitude toward vaccinations administered by pharmacists in national vaccination centres.

Cannabis use in patients with insomnia and sleep disorders: Retrospective chart review.

Background: Medical cannabis has been increasingly used in Canada after being sanctioned by Health Canada in 2001. Insomnia and sleep disorders are among the most common conditions for which patients report using cannabis. Current research shows cannabis may have a beneficial effect in sleep disorders and may improve patient-reported sleep scores. Methods: A retrospective chart review was conducted at Hybrid Pharm community pharmacy in Ottawa, Ontario, and included patients who were interested in, or already using, medical cannabis for sleep disorders. A qualitative, exploratory approach was taken to evaluate the descriptive efficacy and safety of medical cannabis when prescribed for insomnia or comorbid conditions. The comprehensive data collection also involved investigating the impact of cannabis on other medication used for insomnia. Results: A total of 38 patients were identified as having adequate follow-up documentation to assess the impact of medical cannabis. At time of data collection, 15 patients (39%) were able to reduce or completely discontinue a prescription medication indicated for sleep. On follow-up, 27 patients (71%) reported a subjective improvement in their sleep or related condition. Only 8 patients (21%) reported any adverse effects from medical cannabis use, and these were manageable and did not require discontinuation of cannabis. Conclusion: This study highlights the importance of a pharmacist's role in the management of cannabis-based therapy, including ongoing supportive care, follow-up and medication management.

Concerns, beliefs and attitudes of pharmacists and pharmacy students on cannabis use in Canada.

Background: Since cannabis has been legalized in Canada for medical and recreational use, there has been an increased demand on pharmacists for cannabis counselling. The objective of this study was to determine the concerns, beliefs and attitudes of Canadian pharmacists and pharmacy students towards using cannabis. Methods: An online survey was synthesized under 3 broad themes: concerns, beliefs and attitudes about cannabis, consisting of 27 questions capturing demographics and Likert scale responding to survey questions. We examined whether there were differences in responses by geographic location (i.e., Ontario, Quebec, Canada), sex or practice setting (i.e., community, hospital). Results: Across Canada, there were 654 survey respondents, with 399 in Ontario and 95 in Quebec. Approximately 24% indicated they had used cannabis since legalization, 69% indicated they believed cannabis should be available for medical and recreational use and 34% indicated their perceptions towards cannabis had become more positive since legalization. Relative to Quebec or the rest of Canada, respondents from Ontario were significantly more likely to be comfortable providing counselling to and answering questions of patients on the safety and efficacy of medical cannabis use. Examining sex differences across Canada, male respondents were more comfortable than female counselling patients on the safety and efficacy of medical cannabis. Conclusion: The current results reinforce the perceived need by pharmacists and pharmacy students for targeted education, and future research in cannabis education should consider potential gender differences in attitudes and beliefs surrounding cannabis therapy.

Evaluating the psychometric properties of the parent-rated Strengths and Difficulties Questionnaire in a nationally representative sample of Canadian children and adolescents aged 6 to 17 years.

BACKGROUND: The Strengths and Difficulties Questionnaire (SDQ) is a brief measure of children's and adolescents' mental health. There are different versions of the questionnaire: a version for children and adolescents to complete by self-reporting, a version for parents and guardians to complete ("parent-rated"), and a version for teachers to complete. The purpose of this study was to examine the psychometric properties of the parent-rated SDQ with a nationally representative sample of Canadian children and adolescents. DATA AND METHODS: Data are from cycle 1 (2007 to 2009), cycle 2 (2009 to 2011), cycle 3 (2012 to 2013) and cycle 4 (2014 to 2015) of the Canadian Health Measures Survey. Data include 7,451 Canadian children and adolescents aged 6 to 17 years (49.3% female). Parents and guardians completed the SDQ by reflecting on their child's behaviour over the past six months. Factorial validity was examined via confirmatory factor analysis, which included testing the original five-factor SDQ model and alternative three-factor and higher-order models. Reliability was assessed through composite reliability scores. Measurement invariance across subgroups was also assessed. RESULTS: The original five-factor (i.e., emotional symptoms, conduct problems, peer problems, hyperactivity and prosocial behaviour) SDQ fit the data satisfactorily, demonstrated evidence of reliability, and was invariant across sex (male vs. female), age (children vs. adolescents) and survey language (English vs. French). The higher-order solution fit the data acceptably, and the three-factor solution did not fit the data well. DISCUSSION: The original five-factor, parent-rated SDQ demonstrates evidence of factorial validity and reliability as a population measure of mental health difficulties among Canadian children and adolescents.

Brain on Fire: Incentive Salience, Hedonic Hot Spots, Dopamine, Obesity, and Other Hunger Games.

This review examines human feeding behavior in light of psychological motivational theory and highlights the importance of midbrain dopamine (DA). Prospective evidence of both reward surfeit and reward deficit pathways to increased body weight are evaluated, and we argue that it is more complex than an either/or scenario when examining DA's role in reward sensitivity, eating, and obesity. The Taq1A genotype is a common thread that ties the contrasting models of DA reward and obesity; this genotype related to striatal DA is not associated with obesity class per se but may nevertheless confer an increased risk of weight gain. We also critically examine the concept of so-called food addiction, and despite growing evidence, we argue that there is currently insufficient human data to warrant this diagnostic label. The surgical and pharmacological treatments of obesity are discussed, and evidence is presented for the selective use of DA-class drugs in obesity treatment.

Changes in the Brain-Derived Neurotrophic Factor Are Associated with Improvements in Diabetes Risk Factors after Exercise Training in Adolescents with Obesity: The HEARTY Randomized Controlled Trial.

Obesity in youth increases the risk of type 2 diabetes (T2D), and both are risk factors for neurocognitive deficits. Exercise attenuates the risk of obesity and T2D while improving cognitive function. In adults, these benefits are associated with the actions of the brain-derived neurotrophic factor (BDNF), a protein critical in modulating neuroplasticity, glucose regulation, fat oxidation, and appetite regulation in adults. However, little research exists in youth. This study examined the associations between changes in diabetes risk factors and changes in BDNF levels after 6 months of exercise training in adolescents with obesity. The sample consisted of 202 postpubertal adolescents with obesity (70% females) aged 14-18 years who were randomized to 6 months of aerobic and/or resistance training or nonexercise control. All participants received a healthy eating plan designed to induce a 250/kcal deficit per day. Resting serum BDNF levels and diabetes risk factors, such as fasting glucose, insulin, homeostasis model assessment (HOMA-B-beta cell insulin secretory capacity) and (HOMA-IS-insulin sensitivity), and hemoglobin A1c (HbA1c), were measured after an overnight fast at baseline and 6 months. There were no significant intergroup differences on changes in BDNF or diabetes risk factors. In the exercise group, increases in BDNF were associated with reductions in fasting glucose (ß = -6.57, SE = 3.37, p = 0.05) and increases in HOMA-B (ß = 0.093, SE = 0.03, p = 0.004) after controlling for confounders. No associations were found between changes in diabetes risk factors and BDNF in controls. In conclusion, exercise-induced reductions in some diabetes risk factors were associated with increases in BDNF in adolescents with obesity, suggesting that exercise training may be an effective strategy to promote metabolic health and increases in BDNF, a protein favoring neuroplasticity. This trial is registered with ClinicalTrials.gov NCT00195858, September 12, 2005 (funded by the Canadian Institutes of Health Research).

Screen time is associated with depressive symptomatology among obese adolescents: a HEARTY study.

UNLABELLED: Obese adolescents spend a disproportionate time in screen-based activities and are at higher risk for clinical depression compared to their normal-weight peers. While screen time is associated with obesity and cardiometabolic risk factors, little is known about the relationship between screen time and mental health. This cross-sectional study examines the association between duration and types of screen time and depressive symptomatology (subclinical symptoms) in a sample of 358 (261 female; 97 male) overweight and obese adolescents aged 14-18 years. Self-report measures assessed depressive symptoms and time spent in different types of screen behavior (TV, recreational computer use, and video games). After controlling for age, ethnicity, sex, parental education, body mass index (BMI), physical activity, caloric intake, carbohydrate intake, and intake of sugar-sweetened beverages, total screen time was significantly associated with more severe depressive symptomatology (ß = 0.21, p = 0.001). After adjustment, time spent playing video games (ß = 0.13, p = 0.05) and recreational computer time (ß = 0.18, p = 0.006) was associated with depressive symptoms, but TV viewing was not. CONCLUSIONS: Screen time may represent a risk factor or marker of depressive symptomatology in obese adolescents. Future intervention research should evaluate whether reducing screen exposure reduces depressive symptoms in obese youth, a population at increased risk for psychological disorders. WHAT IS KNOWN: • Screen time is associated with an increased risk of obesity in youth. • Screen time is associated with an adverse cardio-metabolic profile in youth. What is New: • Screen time is associated with more severe depressive symptoms in overweight and obese adolescents. • Time spent in recreational computer use and playing video games, but not TV viewing, was associated with more severe depressive symptoms in overweight and obese adolescents.

The mediating role of energy intake on the relationship between screen time behaviour and body mass index in adolescents with obesity: The HEARTY study.

Adolescents spend up to 6-8 h/day in sedentary screen behaviour and screen time is an independent risk factor for obesity. However, the mechanisms by which screen time confers obesity risk remain unclear. Via community level recruitment this study examined whether the relationship between screen time behaviours and body mass index (BMI: kg/m2) was mediated by total energy intake or macronutrient consumption. In a cross-sectional study of post-pubertal adolescents (N = 283: 86M, 197F) with overweight or obesity at baseline of an intervention for weight control, we examined self-reported total energy intake (mean Calories from 3 day food diary), macronutrient intake (grams/day of carbohydrate, fat, protein) and total screen time (aggregate of hours/day watching TV, playing seated video games, and recreational computer use). BMI was objectively measured and converted to standardized scores (z-BMI). Simple and multiple mediation analyses were conducted using the bootstrapping approach described by Preacher and Hayes. Covariates included age, sex, ethnicity, parental education, Tanner stage, and self-reported physical activity. The relationship between screen time and z-BMI was significantly mediated by energy intake. Higher levels of carbohydrate intake, but not fat or protein intake, significantly mediated the relationship between screen time and z-BMI (95% bias-corrected and accelerated confidence interval [0.0004, 0.0074]). Higher carbohydrate intake mediated the relationship between TV viewing and z-BMI, and video gaming and z-BMI. In conclusion, the relationship between screen time and BMI appears to be mediated by increased energy intake, primarily in the form of higher carbohydrate intake. It is possible that reducing time spent watching TV and playing video games may reduce food intake and help promote dietary adherence needed for weight management in obese adolescents. CLINICAL TRIAL REGISTRATION: ClinicalTrials.gov ID: NCT00195858.

Screen time is independently associated with health-related quality of life in overweight and obese adolescents.

AIM: Excessive screen time and diminished health-related quality of life (HRQoL) are greater problems for obese than nonobese adolescents, but no research has examined the relationship between these two variables. This study examined the association between screen time and HRQoL in overweight and obese adolescents. METHODS: A sample of 358 overweight and obese adolescents aged 14-18 years were assessed at baseline between 2005 and 2010 as part of the Canadian Healthy Eating, Aerobic and Resistance Training in Youth (HEARTY) trial. We used the Pediatric Quality of Life (PEDS-QL) and other self-report measures to assess HRQoL and screen time, defined as how long the 261 females and 97 males spent viewing TV, using the computer and playing video games. RESULTS: After adjusting for socio-demographic variables, adiposity, physical activity and diet, screen time duration was associated with reduced overall HRQoL (adjusted r = -0.16, ß = -0.16, p = 0.009) and psychosocial HRQoL (adjusted r = -0.16, ß = -0.18, p = 0.004), but not physical HRQoL. No differences were found between males and females. CONCLUSION: Screen time was associated with reduced overall and psychosocial HRQoL in overweight and obese adolescents. Future research should determine whether reducing screen time improves overall and psychosocial HRQoL in obese adolescents.

Effects of 2 months of methylphenidate on energy expenditure in individuals with obesity: A randomized, double-blind, placebo-controlled pilot study.

Methylphenidate (MPH) has been previously shown to increase resting energy expenditure (REE) in individuals of normal weight; however, the effects on individuals living with obesity are currently unknown. Ten individuals living with obesity were randomly assigned to undergo 60 days of MPH administration with a daily dose of 0.5 mg/kg body weight or a placebo control. REE was measured before and after the 60-day intervention. There was a trend toward significance for group × time interaction on REE (p = 0.082) with a large effect size (η2 = 0.331), with MPH administration increasing REE compared to a decrease in placebo control. Preliminary findings from this pilot study show that MPH has the potential to counter the adaptive thermogenic process commonly seen in weight loss. This is a unique finding among pharmacotherapies, as no approved obesity drugs measurably impact REE.

The BDNF Val66Met polymorphism and health-related quality of life in youth with obesity.

The brain derived-neurotrophic factor (BDNF) Val66Met polymorphism causes functional changes in BDNF, and is associated with obesity and some psychiatric disorders, but its relationship to health-related quality of life (HRQoL) remains unknown. This study examined, in youth with obesity, whether carriers of the BDNF Val66met polymorphism Met-alleles (A/A or G/A) differed from noncarriers (G/G) on HRQoL. The participants were 187 adolescents with obesity. Ninety-nine youth were carriers of the homozygous Val/Val (G/G) alleles, and 88 were carriers of the Val/Met (G/A) or Met/Met (A/A) alleles. Blood samples were drawn in the morning after an overnight fast for genotyping. HRQoL was measured using the Pediatric-Quality of Life core version. Compared to carriers of the Val66Met Val (G/G) alleles, carriers of the Met-Alleles reported significantly higher physical -HRQoL (p = 0.02), school-related HRQoL, (p = 0.05), social-related HRQoL (p = 0.05), and total HRQoL (p = 0.03), and a trend for Psychosocial-HRQoL. Research is needed to confirm our findings and determine whether carriers of the BDNF Val66Met homozygous Val (G/G) alleles may be at risk of diminished HRQoL, information that can influence interventions in a high-risk population of inactive youth with obesity.

The TaqIA RFLP is associated with attenuated intervention-induced body weight loss and increased carbohydrate intake in post-menopausal obese women.

INTRODUCTION: Polymorphisms of the dopamine receptor D2 (DRD2) gene have been associated with obesity phenotypes. Our aim was to examine if the genotype of TaqIA Restriction Fragment Length Polymorphism (RFPL) was related to an attenuated weight loss response or to changes in energy expenditure (EE) and food preference before and after weight loss. methods: Obese post-menopausal women (age=57.1 ± 4.6 yr, weight=85.4 ± 15.4 kg and BMI=32.8 ± 4.5 kg/m(2)) were genotyped for TaqIA (n=127) by using PCR-RFLP analysis and categorized as possessing at least one copy of the A1 allele (A1(+)) or no copy (A1(-)). Women were randomized into two groups, caloric restriction (CR) and caloric restriction+resistance training (CRRT) and in this study were further classified as follows: A1(+)CR, A1(+)CRRT, A1-(-)CR and (-)A1(-)CRRT. Body composition, total daily EE, physical activity EE, Resting EE (REE), and energy intake were obtained at baseline and post-intervention using DXA, doubly-labeled water, indirect calorimetry, and 3-day dietary records, respectively. RESULTS: Overall, all of the anthropometric variables and REE significantly decreased post-intervention (p<0.001). Women in the CRRT group lost significantly more fat mass (FM) than the CR women (p<0.05). There were significant time by group by allele interactions for attenuated body weight (BW), BMI, and FM loss for A1(+) (vs. A1(-)) in CRRT (p<0.05) and for increased % carbohydrate intake (p<0.01). CONCLUSION: TaqIA genotype was associated with body weight loss post-intervention; more specifically, carriers of the A1 allele lost significantly less BW and FM than the A1(-) and had increased carbohydrate intake in the CRRT group.

Critical Appraisal Tools to Aid Pharmacists in Evidence-Based Practice: A Narrative Review.

Background: Pharmacists and allied health researchers need to ensure that their practice is supported by current, evidence-based information. Critical appraisal tools have been developed to aid in this process. Objectives: To analyze the current landscape of critical appraisal tools and to create an aid for pharmacists and other allied health researchers to use in comparing various tools and choosing the best one for each particular study design. Data Sources: A literature search of the PubMed, University of Toronto Libraries, and Cochrane Library databases was conducted in December 2021, to generate an up-to-date list of critical appraisal tools. The tools were then summarized in a descriptive table. Study Selection and Data Extraction: Review articles, original manuscripts, and tool webpages were examined to develop a comparison chart based on the user-friendliness, efficiency, comprehensiveness, and reliability of each tool. Results: Fourteen tools were found through the literature search. These tools were compared using the findings of included review articles, and a comparison chart was created to aid pharmacists and allied health researchers in selecting the appropriate tool for their practice. Conclusions: There are many standardized critical appraisal tools that can help in assessing the quality of evidence, and the summary list of tools developed and reported here can help health care researchers to compare among them and choose the best one. No tools were found that have been specifically adapted to serve the needs of pharmacists when assessing scientific articles. Future research should examine how existing critical appraisal tools can better identify common data elements that are essential to evidence-based decision-making in pharmacy practice.

Contexte: Les pharmaciens et les chercheurs en soins de la santé doivent faire en sorte que leur pratique soit étayée par des informations actualisées et fondées sur des données probantes. Des outils d'évaluation critique ont été développés pour faciliter ce processus. Objectifs: Analyser le paysage actuel des outils d'évaluation critique et créer une aide que les pharmaciens et les autres chercheurs paramédicaux peuvent utiliser pour comparer divers outils et choisir le meilleur pour chaque conception d'étude particulière. Sources des données: Une recherche documentaire dans trois bases de données (PubMed, les University of Toronto Libraries et la Cochrane Library) a été menée en décembre 2021 afin de générer une liste actualisée d'outils d'évaluation critique qui ont ensuite été résumés dans un tableau descriptif. Sélection des études et extraction des données: Des articles de synthèse, des manuscrits originaux et des pages Internet d'outils ont été examinés pour dresser un tableau comparatif basé sur la convivialité, l'efficacité, l'exhaustivité et la fiabilité de chaque outil. Résultats: Quatorze outils ont été trouvés grâce à la recherche documentaire. Ils ont été comparés à l'aide des résultats des articles de synthèse inclus, et un tableau comparatif a été créé pour aider les pharmaciens et les chercheurs en soins de la santé à sélectionner l'outil approprié pour leur pratique. Conclusions: De nombreux outils d'évaluation critique normalisés peuvent aider à évaluer la qualité des données probantes, et la liste récapitulative des outils développés et rapportés ici peut aider les chercheurs en soins de santé à les comparer et à choisir le meilleur. Aucun outil spécifiquement adapté pour répondre aux besoins des pharmaciens lors de l'évaluation d'articles scientifiques n'a été trouvé. Les recherches futures devraient se pencher sur la manière dont les outils d'évaluation critique existants peuvent mieux identifier les éléments de données communs qui sont essentiels à la prise de décision fondée sur des données probantes dans la pratique de la pharmacie.

Exploring the Role of Pictograms in the Comprehension of Pain.

Introduction: Pain is both difficult to see and to articulate and this is challenging for both patients and clinicians. The aim of this study was to develop and test pictograms to describe different pain qualities. Methods: 22 pictograms were developed for evaluation based on pain qualities of the short form McGill Pain Questionnaire, version 2 (SF-MPQ-2). An online matching survey was conducted and disseminated via social media in 2021. Results: An overall matching of 66% or higher between pictogram and pain qualities descriptors was considered a proper matching. This study was carried out internationally (males = 57, age=41y.o. ±16; females = 155, age=41y.o.±17) and in Poland (males=49, age =35y.o.±17; females = 164, age=35y.o.±16). There were 14 pictograms that did not achieve 66% matching in any country. 8 pictograms mutually in all subgroups achieved a matching score of ≥66% regardless of geographic location, sex, income, or education level. Discussion and Conclusions: These 8 pictograms can be used clinically once they have been redrawn to improve consistency, and future research in the design of pictograms representing pain qualities of the SF-MPQ-2 should focus on design improvements for the remaining 14 pain qualities with poor comprehensibility.

Effects of the HEARTY exercise randomized controlled trial on eating behaviors in adolescents with obesity.

Background: There are well-recognized benefits of behavioral interventions that include exercise for children and adolescents with obesity. However, such behavioral weight management programs may precipitate unintended consequences. It is unclear if different exercise modalities impact eating behaviors differently in youth with obesity. Objectives: The purpose of this study was to examine the effects of aerobic, resistance, and combined aerobic and resistance exercise training on eating attitudes and behaviors (uncontrolled eating, restrained eating, emotional eating, external eating and food craving) among adolescents with overweight and obesity. Methods: N = 304 (70% female) adolescents with overweight and obesity participated in the 6-month Healthy Eating Aerobic and Resistance Training in Youth (HEARTY) randomized controlled trial. All participants were inactive post-pubertal adolescents (15.6 ± 1.4 years) with a mean BMI = 34.6 ± 4.5 kg/m2. The Food Craving Inventory (food cravings), Dutch Eating Behavior Questionnaire (restrained eating, emotional eating, external eating), and the Three-Factor Eating Questionnaire (uncontrolled eating) were used to assess eating attitudes and behaviors. Results: All exercise groups showed within-group decreases in external eating and food cravings. Participants randomized to the Combined training group and were more adherent showed the greatest improvements in eating behaviors and cravings. Conclusions: A 6-month exercise intervention produced improvements in disordered eating behaviors and food cravings, but effects may be gender and modality-specific. Findings highlight the need to tailor exercise intervention to participant characteristics for the promotion of healthier eating and weight management outcomes in youth with obesity.Clinical Trial Registration # and Date: ClinicalTrials.Gov NCT00195858, September 12, 2005.
