Introduction: Despite being legal in Canada, the vaporized liquid of vaping systems contains several chemicals presenting unknown risks to lung health and little is known about their use in patients visiting the emergency department (ED). This study explores associations between exposure to inhaled products and respiratory presentations in the ED. Methods: A cross-sectional lung health survey among patients presenting to a Canadian ED was conducted, exploring the association between inhaled toxic exposures (e.g., vaping, cannabis and cigarette smoking) and visits related to respiratory symptoms. Eligible participants were ambulatory (CTAS 2 to 5), stable, adults (≥ 17 years) visiting the ED from July to November, 2019. Results are described as frequencies and percentages (categorical variables) and medians with interquartile range (IQR, continuous variables). Univariate and multivariate logistic regression models report associations as odds ratios (OR) with 95% confidence intervals (CIs). The Health Research Ethics Board approved the study. Results: From 1433 eligible patients, 1024 (71%) completed the survey. The median age was 43.5 (IQR: 29, 60), and 51% were female. Overall, 177 (17%) reported ≥1 respiratory symptoms and 83 (8%) reported using any vaping products. In a univariate regression analysis, exposure to vaping was positively associated with ED visits related to respiratory symptoms (OR 2.11, 95% CI: 1.26 to 3.54). In the multivariate model, vaping and a previous diagnosis of ≥1 respiratory conditions showed positive association with respiratory-related ED visits (OR 1.86, 95% CI: 1.03 to 3.33; and OR 2.13, 95% CI: 1.50 to 3.02, respectively). There was evidence of an additive effect of the combined exposure to cigarettes and vaping and respiratory-related ED visits (OR 3.22, 95% CI: 1.61 to 6.43). Smoking cannabis and cigarettes alone were not associated with increased risk of respiratory-related visits. Conclusion: Using vaping products increased the occurrence of respiratory-related ED visits, particularly in people with pre-existing lung conditions. A dose-response relationship exists where the risk is highest in patients inhaling a combination of toxins. Contrary to previous assumptions, the use of vaping products has a negative impact on lung health.

Introduction: Inhaled toxins from tobacco smoking, cannabis leaf smoking as well as vaping/e-cigarette products use are known causes of cardio-respiratory injury. While tobacco smoking has decreased among Canadian adults, there are now several other forms of legal inhalant products. While legal, the evidence of benefit and safety of vaping is limited. Of concern, cases of e-cigarette or vaping products use associated lung injury (EVALI) have been accumulating in the U.S. and now in Canada. Despite this, very little is known about the inhalation exposure of emergency department (ED) patients; this study was designed to explore lung health in the ED. Methods: We investigated the prevalence of exposure to vaping, tobacco and cannabis among patients presenting to a Canadian ED from July to November 2019. Ambulatory (CTAS 2 to 5), stable, adult (≥ 17 years) patients were prospectively identified and invited to complete a survey addressing factors related to lung health (previous diagnosis of respiratory conditions and respiratory symptoms at the ED presentation) and information on current exposure to vaping, tobacco and cannabis smoking. Categorical variables are reported as frequencies and percentages; continuous variables are reported as medians with interquartile range (IQR). The study was approved by the Health Research Ethics Board. Results: Overall, 1024 (71%) of 1433 eligible patients completed the survey. The median age was 43.5 (IQR: 29, 60), and 51% were female. A total of 351 (31%) participants reported having been previously diagnosed with ≥1 respiratory conditions, and 177 (17%) were visiting the ED as a result of ≥1 respiratory symptoms (e.g., cough, shortness of breath, wheezing). Daily tobacco smoking was reported by 190 (19%), and 83 (8%) reported using vaping/e-cigarette products. Cannabis use within 30 days was described by 80 (15%) respondents. Exposure to tobacco and vaping products was reported by 39 (4%) participants, 63 (6%) reported using tobacco in combination with cannabis smoking, and 3% reported combining vaping and cannabis use. Conclusion: Patients seeking care in the ED are exposed to a large quantity of inhaled toxins. Vaping products, considered the cause of the most recent epidemic of severe lung injury, are used in isolation and in combination with other smoking products in Canada. These exposures should be documented and may increase the risk of lung health injuries and exacerbations of chronic respiratory conditions.

Abstract Vaso-occlusive crises (VOC) are a common cause of emergency department (ED) visits for children with sickle cell disease (SCD). To better understand our patient population and compare with reports from other centers, we sought to describe the presentation, management, and disposition of children with VOC at our center’s ED. We also aimed to identify predictors of hospital admission. We retrospectively reviewed hospital records of all patients with SCD, age 8–19 years, who presented to our urban pediatric ED in 2003 with a chief complaint of pain. We identified all subjects diagnosed with VOC and not another cause of pain. We obtained the following data for each: SCD genotype; duration of VOC and treatment prior to ED presentation; the nature of analgesia and use of intravenous fluids (IVF) in the ED; hemoglobin (Hgb) concentration; and disposition (admitted, discharged, discharged with subsequent ED visit for same crisis). Categorical variables were evaluated by the χ2 and Fisher exact tests and continuous variables by the t-test. Odds ratios (OR) and 95% confidence intervals (CI) were calculated where appropriate. In 2003, there were 320 ED visits for patients with SCD and pain. Among these, there were 279 diagnoses of VOC in 105 individual patients: 45 had one visit, 25 two visits, and 16 ≥5 visits. Mean number of visits per patient was 2.7; 23 (22%) patients accounted for 145 (55%) visits. Homozygous sickle cell anemia (Hgb SS) was present in 73/105 patients, accounting for 222 (79%) ED visits. Overall admission rate was 179/279 (64%), with 167/179 admitted on their first visit and 12 on their return visit. Subjects with Hgb SS accounted for 147/179 (82%) admissions. Among those discharged who later returned to the ED during the same VOC, the admission rate was 86% (5 returned in 24 hours, 5 in 48 hours, 3 in 72 hours, and one 4 days later). Pre-ED home opioid use was reported in 75% of visits and was associated with increased likelihood of discharge (OR 1.63, CI 0.94–2.84, p=0.082). Duration of VOC before presentation did not significantly affect admission rate and averaged 53.2 hours for admitted patients and 49.7 hours for those discharged (p=0.689). Patients who received IVF in the ED (219/279; 79%) were less likely to be admitted (31% vs 56%, p<0.001). Hgb concentration was increased in 61%, decreased in 36% and unchanged in 3% of patients from steady-state values and was not associated with admission. After receiving 2 doses of morphine, 31 patients were discharged from the ED, while only 5 patients were discharged after receiving 3 or 4 doses of morphine. A departmental VOC protocol was followed for 25.4% of patients, with no impact on admission rate (p=0.290). In this retrospective analysis of a large series of pediatric sickle cell ED visits, patients presented later in their VOC, and admission rate was higher than previously reported. A small proportion of older patients with SCD accounted for most ED visits and hospitalizations. Hgb variation from steady-state was neither clinically significant nor predictive of admission or discharge. In contrast to previous studies, receiving IVF in the ED was associated with a greater likelihood of discharge. Home opioids prior to ED presentation seemed to decrease hospital admission. Adherence to our center’s VOC protocol did not appear to influence disposition from the ED.

Skipping Breakfast

Objectives: To find out the prevalence of skipping breakfast and its association with different domains of cognitive function. Materials and Methods: Using inclusion and exclusion criteria, a representative sample of 184 under graduate students were included. Cognitive function was assessed using previously validated scales of measurement like FDS (Forward Digit Span) and BDS (Backward Digit Span) for assessing short-term and working memory respectively and MMSE (Mini Mental Scale Examination) for assessing global cognitive function. Categorical variables were expressed as a percentage and continuous variables were expressed in terms of mean and median. Mann Whitney U test was used to compare the medians. A P-value of <0.05 was considered statistically significant. Results: Almost three-quarter of the study participants were found to have skipped breakfast either once or more than once in a week. All the three scores (FDS, BDS and MMSE) were higher among those who took breakfast. However; only the differences in BDS and MMSE scores were statistically significant. Conclusion: It was observed that those who took breakfast had higher BDS and MMSE scores indicating positive association between having breakfast and certain domains of cognitive function. Further, studies with robust study designs are needed to elicit the association of skipping breakfast and cognitive function, which would contribute further to our existing knowledge.

Fall Injury

Background: Child unintentional injuries have become a hot topic worldwide, and substantial regional disparities existed in causes and characteristics. To date, limited data are available to investigate the causes and characteristics of child unintentional injuries from hospitals for children in China.Methods: A cross-sectional study was conducted between January 2017 and December 2018 in Shanghai, China. Patients aged &lt;18 years with an unintentional injury presented to the emergency department were enrolled. Demographic information, Pediatric Risk for Mortality III score, and outcome variables were retrieved from electronic health records (EHRs). Frequencies and proportions of categorical variables and means and SDs of continuous variables are presented. Chi-square test and Student's t-test were used for the comparison between groups, as appropriate. Logistic regression analysis was used to estimate potential risk factors for admission to the hospital.Results: A total of 29,597 cases with unintentional injuries were identified between January 2017 and December 2018, with boys vs. girls ratio of 1.75. Preschool children account for approximately two-thirds of unintentional injuries in the emergency department. A distinctive pattern of mechanisms of unintentional injuries between gender was documented, and sports injury was significantly higher in boys than in girls (10.2 vs. 7.8%). Compared with Canadian Emergency Department Triage and Acuity Scale (CTAS) Grade 3 patients, Grade 2 [odds ratio (OR) = 2.99, 95% CI = 1.93–4.63, P &lt; 0.001] and Grade 1 (OR = 74.85, 95% CI = 12.93–433.14, P &lt; 0.001) patients had higher risk of inhospital admission. For causes of injuries, compared with falling, foreign body and poison had a lower risk of inhospital admission, while transport injury (OR = 1.31, 95% CI = 1.07–1.59, P = 0.008) and high fall injury (OR = 2.58. 95% CI =1.48–4.49, P &lt; 0.001) had a significantly higher risk of admission.Conclusions: There was a significant relationship between age-groups and unintentional injuries between gender, with decreased injuries among girls growing up older. Preventive measures should be taken to reduce transport injury and high fall injury, which had a significantly higher risk of admission.

Abstract Background. Some studies have reported a positive association between parents and their offspring’s physical activity (PA), but few have examined the difference in these associations concerning both genders. The objective of this study was to establish the association between moderate-vigorous physical activity (MVPA) and mode of commuting (MC) of the parents with their offspring’s MC, by gender and age group. Methods. This cross-sectional study included 686 parents (mothers: 52.8%) and their offsprings (33.8% girls). Each participant completed a questionnaire on PA and MC. Chi-square test, Odds Ratio for categorical variables and lineal regressions for continuous variables were used to examine the associations between the parents and their offspring. Results. An inverse association was found between fathers-children in the weekend MVPA in children and between mothers-adolescents in out-of-school and weekend MVPA in adolescents, specifically, an inverse association was found in MVPA between mothers-girls and 2) the different parents’ MC to work were positively associated with the MC to school in children and adolescents except for the association AC parents-adolescents and specifically, the AC was mainly associated between mothers and girls and boys. Conclusion. This study emphasizes the importance of involving parents in school-based interventions to create a positive ripple effect in PA-related behaviours.

Background. Workplace violence (WPV) is a major healthcare problem with important consequences in healthcare areas and may impact negatively not only healthcare workers but also the quality and safety of patient care. Objectives: This an observational online web-based survey using Google® Modules, specifically aiming to investigate the phenomenon of WPV in Italian healthcare services. Methods. Data collection for this study lasted one month, with the questionnaire available from 1 May 2021 to 31 May 2021. Continuous variables were considered as either mean ± standard deviation (SD) or median and interquartile range (IQR) based on their distribution. Comparison between groups was assessed by unpaired t-test or Mann–Whitney U test according to variable distribution. Categorical variables were analyzed using the chi-squared test. Results. The study population consisted of 203 healthcare workers, represented by nurses (61.6%), medical doctors (16.8%), patient care assistants (4.9%), and others (16.7%). Female gender was associated with a 2.6 times higher risk for the presence of aggression (p = 0.034), and nurse as a job with about 4 times increased risk for the presence of aggression (p = 0.006). The risk for aggression increased by 5% for each year of work experience. Conclusions. WPV is still matter of concern in Italian healthcare services. A strong organizational effort is demanded from healthcare institutions in order prevent internal and external violence in healthcare settings.

Factors Affecting

11040 Background: Although women outnumber men in US medical school enrollment, women constitute < 50% of faculty in academic oncology. This study aimed to determine factors affecting women oncologists’ decisions to pursue academic versus non-academic oncology in Hematology/Oncology (HO), Pediatric Oncology (PO), Radiation Oncology (RO), and Surgical Oncology (SO), and to characterize the challenges women oncologists face. Methods: A survey was designed to collect cross-sectional data on factors affecting career choices among US women oncologists. The survey was distributed via email and social media. Data were collected anonymously and analyzed using t-tests for continuous variables and Chi-squared tests for categorical variables. Results: Six hundred sixty-seven women oncologists responded: 245 (45.3%) specialized in HO, 173 (25.9%) RO, 88 (13.2%) PO, 56 (8.4%) SO, and 48 (7.2%) other. Four-hundred twenty-two (63.2%) women identified as an academic oncologist (AO); 245 (36.8%) women identified as a non-academic oncologist (non-AO). Approximately ¼ of women oncologists reported their partner (156, 23.5%) or family (176, 26.4%) extremely or moderately impacted their decision whether to pursue academic practice. There was no difference in the timing of childbearing between AO and non-AO. AO perceived the biggest sacrifice of pursuing academics to be time with loved ones (181, 42.9%). Non-AO perceived the biggest sacrifice for AO to be pressure for academic promotion (102, 41.6%), which was the third most common response (44, 18.0%) among AO. Thirty-three (7.9%) AO and 5 (2.0%) non-AO reported feeling that they rarely or never have a sense of belonging in their work environment (p < 0.01). AO and non-AO had significantly different perceptions on how their gender impacted their ability to obtain a chosen job (p < 0.01), with 100 (23.8%) AO and 52 (21.2%) non-AO reporting a negative or somewhat negative impact, and 116 (27.6%) AO and 101 (41.2%) non-AO reporting a positive or somewhat positive impact. More than half of women surveyed (230 AO, 54.6%; 123 non-AO, 50.6%; p = 0.61) felt that they were somewhat or much less likely to be promoted compared to male colleagues. The majority of women reported they would choose the same career path again (71% of AO, 69% of non-AO); however, 92 (21.9%) of AO responded that they were likely or very likely to pursue a career outside academics in the next 5 years. Conclusions: While partners/family have a substantial impact on 1 in 4 women oncologists, this does not differ between AO and non-AO. Significantly more non-AO find their gender to have positively impacted their ability to obtain their chosen job. In contrast, a meaningful number of AO report a poor sense of belonging and perceived discrimination in obtaining jobs and being promoted; 1 in 5 are considering leaving academia. Academic oncology remains at high risk for continued gender inequality if the culture is not addressed.

Introduction: Emergency Department (ED) Transition Coordinators (TC) have been introduced to many EDs. In Alberta, the EDTC role was designed to evaluate the home needs of senior patients (75 years of age) to enable safe return home after an ED visit, thereby mitigating admissions and return ED visits. The effectiveness of this role at achieving its objectives has received limited evaluation. Methods: TCs assess all ED patients 75 years old, and physicians request TC assessment for patients <75 years. The TC assessment includes completing a Transitional Assessment Referral (TAR) form that collects information on comorbidities, living arrangements, connections to community and homecare services, independence in activities of daily living (ADLs), and referrals, and disposition. Trained research staff extracted data from consecutive TARs for patients presenting during April 2017 into a REDCap database. The proportions of patients seen by TCs who were admitted, had an unplanned return to the ED within the study period, or received a new homecare referral were assessed. Categorical variables are reported as proportions; continuous variables are reported as mean and standard deviation (SD) or median and interquartile range (IQR), as appropriate. Results: In April 2017, there were 9849 visits to the ED; of these, TCs assessed 478 patients during 500 visits. The mean age was 82 (SD=11.2) and 41% were male; 22 patients presented twice during April 2017. Patients had a median of 2 (IQR: 1, 5) co-morbidities and 40 (8%) patients reported falls in the past 90 days (median=1; IQR: 1, 2). Overall, 144 (29%) patients lived in a care facility, while 204 (41%) lived at home; residence was unclear or not documented for 152 (30%). Patients reported being independent in a median of 9/14 (IQR: 3, 13) ADLs. An existing homecare connection or receipt of homecare services was documented for 185 patients (37%). Finally, 59 (12%) visits included a new or updated homecare referral, while 200 (33%) ED visits ended in admission. Conclusion: Elderly patients seen in the ED assessed by EDTCs are complex, and despite being well connected, they frequently need hospitalization. In a small proportion of cases, additional or new home care resources are required prior to ED discharge; however, few patients returned to the same ED during the one month study period. Given the high proportion of patients assessed, further evaluation of outcomes is warranted.

Polymyositis (PM) and dermatomyositis (DM) are autoimmune-mediated multisystemic myopathies, characterized mainly by proximal muscle weakness. A connection between epilepsy and PM/DM has not been reported previously. Our study aim is to evaluate this association. A case–control study was conducted, enrolling a total of 12,278 patients with 2085 cases (17.0%) and 10,193 subjects in the control group (83.0%). Student’s t-test was used to evaluate continuous variables, while the chi-square test was applied for the distribution of categorical variables. Log-rank test, Kaplan–Meier curves and multivariate Cox proportional hazards method were performed for the analysis regarding survival. Of the studied 2085 cases, 1475 subjects (70.7%) were diagnosed with DM, and 610 patients (29.3%) with PM. Participants enrolled as cases had a significantly higher rate of epilepsy (n = 48 [2.3%]) as compared to controls (n = 141 [1.4%], p < 0.0005). Using multivariable logistic regression analysis, PM was found only to be significantly associated with epilepsy (OR 2.2 [95%CI 1.36 to 3.55], p = 0.0014), whereas a non-significant positive trend was noted in DM (OR 1.51 [95%CI 0.99 to 2.30], p = 0.0547). Our data suggest that PM is associated with a higher rate of epilepsy compared to controls. Physicians should be aware of this comorbidity in patients with immune-mediated myopathies.

Background/Aim: Obesity in adolescents is increasing; as such, the aim of this study was to determine the prevalence of obesity in Mexican adolescents and examine its possible association with hours of sleep. Methods: A school-based cross-sectional study was carried out. This study included 863 adolescents aged between 11 and 16 years. The prevalence of obesity was estimated using the body mass index (BMI). The duration of sleep (and other information) was assessed by a self-reported questionnaire. The Cochran–Mantel–Hansel test for categorical variables and a general linear model for continuous variables were used to evaluate the interaction effect of BMI and sex with respect to sleeping and assessed activity conditions. Results: It was found that 47.6% of the adolescents were overweight/obese. Men were more frequently overweight/obese than women (52.6% vs. 41.8%, p = 0.002). Moreover, overweight/obese adolescents were younger and spent fewer daily hours watching television (p < 0.05). Men practiced sports more hours per week than women (p = 0.04). However, women spent more daily time on the internet (p = 0.05), and overweight/obese adolescent women slept fewer hours than overweight/obese men and adolescents with normal weight (p = 0.008). Conclusions: The development of strategies for the prevention of overweight/obesity and the improvement of sleep duration should include a gender perspective to improve health habits in Mexican adolescents.
