Prevalence of Asthma and Risk Factors for Asthma-Like Symptoms in Aboriginal and Non-Aboriginal Children in the Northern Territories of Canada

BACKGROUND: Few studies have investigated the prevalence and risk factors of asthma in Canadian Aboriginal children.OBJECTIVE: To determine the prevalence of asthma and asthma-like symptoms, as well as the risk factors for asthma-like symptoms, in Aboriginal and non-Aboriginal children living in the northern territories of Canada.METHODS: Data on 2404 children, aged between 0 and 11 years, who participated in the North component of the National Longitudinal Survey of Children and Youth were used in the present study. A child was considered to have an asthma-like symptom if there was a report of ever having had asthma, asthma attacks or wheeze in the past 12 months.RESULTS: After excluding 59 children with missing information about race, 1399 children (59.7%) were of Aboriginal ancestry. The prevalence of asthma was significantly lower (P<0.05) in Aboriginal children (5.7%) than non-Aboriginal children (10.0%), while the prevalence of wheeze was similar between Aboriginal (15.0%) and non-Aboriginal (14.5%) children. In Aboriginal children, infants and toddlers had a significantly greater prevalence of asthma-like symptoms (30.0%) than preschool-aged children (21.5%) and school-aged children (11.5%). Childhood allergy and a mother’s daily smoking habit were significant risk factors for asthma-like symptoms in both Aboriginal and non-Aboriginal children. In addition, infants and toddlers were at increased risk of asthma-like symptoms in Aboriginal children. In analyses restricted to specific outcomes, a mother’s daily smoking habit was a significant risk factor for current wheeze in Aboriginal children and for ever having had asthma in non-Aboriginal children.CONCLUSIONS: Asthma prevalence appears to be lower in Aboriginal children than in non-Aboriginal children. The association between daily maternal smoking and asthma-like symptoms, which has been mainly reported for children living in urban areas, was observed in Aboriginal and non-Aboriginal children living in northern and remote communities in Canada.

Meta Analyses

Introduction: Cancer patients are at increased risk of experiencing cardiotoxicity during their fluoropyrimidine-based chemotherapy. However, risk factors for fluoropyrimidine-induced cardiotoxicity (FIC) are not entirely understood. Methods: We searched PubMed, PsycINFO, IPA, CINAHL, Web of Science and ClinicalTrials.gov for studies published between January 1, 1990 and December 31, 2019, examining risk factors for cardiotoxicity induced by 5-fluorouracil, capecitabine or floxuridine. Two reviewers independently assessed publication quality and extracted study-level data into standardized evidence tables. Review Manager 5 software was used to convert data to risk ratios (RRs) and calculate pooled RRs for meta-analyses using a random-effects method. We conducted a Cochran’s Q test and obtained I 2 index to quantify study heterogeneity in each meta-analysis, with prediction interval (PI) to show the expected range of true effects in future similar studies. Results: Of 690 publications identified for abstract and title screening, 22 unique studies were included in the final review, and 20 of them had sufficient data for meta-analyses. Results indicated that patients undergoing capecitabine-based combination therapy had a higher risk of FIC than those with capecitabine monotherapy (pooled RR=1.61, 95% CI=1.01-2.55, I 2 =0%, 95% PI=0.08-31.71). Also, patients with pre-existing cardiac disease (pooled RR=3.01, 95% CI=2.02-4.49, I 2 =42%, 95% PI=1.03-8.78), hypertension (pooled RR=1.52, 95% CI=1.20-1.93, I 2 =0%, 95% PI=1.08-2.13) or smoking habit (pooled RR=2.22, 95% CI=1.03-4.78, I 2 =39%, 95% PI=0.15-32.46) had a significantly higher risk of FIC than their counterparts, while gender and comorbidities including diabetes, hyperlipidemia, and obesity were not significant risk factors of FIC. Conclusions: Cancer patients with pre-existing cardiac disease, hypertension, and smoking behavior had a higher risk of FIC when they are undergoing fluoropyrimidine-based treatments. Further research is needed to develop risk assessment tools for a risk prediction of FIC among cancer patients, which could advance risk stratification strategies and improve patient outcomes during the application of fluoropyrimidine-based treatments.

Background. Some studies with inconclusive results have reported a link between sarcoidosis and an increased risk of pulmonary embolism (PE). This study aimed at assessing a possible correlation between potential risk factors and PE in sarcoidosis patients. Methods. A total of 256 sarcoidosis patients (84 males and 172 females; mean age at diagnosis 49 ± 13) were enrolled after giving written informed consent. Clinical evaluations, laboratory and radiology tests were performed to evaluate the presence of pulmonary embolism. Results. Fifteen sarcoidosis patients with PE (4 males and 11 females; mean age at diagnosis 50 ± 11), diagnosed by lung scintigraphy and 241 sarcoidosis patients without PE (80 males and 161 females; mean age at diagnosis 47 ± 13), were observed. There was a statistically significant increase of the presence of antiphospholipid antibodies in the sarcoidosis group with pulmonary embolism. There was no statistically significant difference between the two groups as to smoking habit, obesity or hereditary thrombophilia frequency (p > 0.05, respectively). Conclusions. This study demonstrates a significant correlation between the presence of antiphospholipid antibody positivity and the pulmonary embolism events in our sarcoidosis patients. Furthermore, we propose screening for these antibodies and monitoring, aimed at timely treatment.

Abstract Background Post-bariatric patients present a surgical challenge within abdominoplasty because of residual obesity and major comorbidities. In this study, we analyzed complications following abdominoplasty in post-bariatric patients and evaluated potential risk factors associated with these complications. Objectives The authors sought to determine the complications and risk factors following abdominoplasty in post-bariatric patients. Methods A retrospective study of patients who underwent abdominoplasty was performed from January 2009 to December 2018 at our institution. Variables analyzed were sex, age, body mass index (BMI), smoking, surgical technique, operative time, resection weight, drain output, and complications. Results A total of 406 patients were included in this study (320 female and 86 male) with a mean age of 44.4 years and a BMI of 30.6 kg/m2. Abdominoplasty techniques consisted of traditional (64.3%), fleur-de-lis technique (27.3%), and panniculectomy without umbilical displacement (8.4%). Overall complications recorded were 41.9%, the majority of these being wound-healing problems (32%). Minor and major complications were found in 29.1% and 12.8% of patients, respectively. A BMI value of ≥30 kg/m2 was associated with an increased risk for wound-healing problems (P = 0.001). The frequency of total complications was significantly related to age (P = 0.007), BMI (P = 0.004), and resection weight (P = 0.001). Abdominoplasty technique tended to influence total complications. Conclusions This study demonstrates in a fairly large sample of post-bariatric patients (n = 406) that abdominoplasty alone can be performed safely, with an acceptable complication rate. Age, BMI, and resection weight are shown to be significant risk factors for total complications. The role of surgical technique needs to be evaluated further. Level of Evidence: 4

Abstract Background Post-thyroidectomy haemorrhage occurs in 1–2 per cent of patients, one-quarter requiring bedside clot evacuation. Owing to the risk of life-threatening haemorrhage, previous British Association of Endocrine and Thyroid Surgeons (BAETS) guidance has been that day-case thyroidectomy could not be endorsed. This study aimed to review the best currently available UK data to evaluate a recent change in this recommendation. Methods The UK Registry of Endocrine and Thyroid Surgery was analysed to determine the incidence of and risk factors for post-thyroidectomy haemorrhage from 2004 to 2018. Results Reoperation for bleeding occurred in 1.2 per cent (449 of 39 014) of all thyroidectomies. In multivariable analysis male sex, increasing age, redo surgery, retrosternal goitre and total thyroidectomy were significantly correlated with an increased risk of reoperation for bleeding, and surgeon monthly thyroidectomy rate correlated with a decreased risk. Estimation of variation in bleeding risk from these predictors gave low pseudo-R2 values, suggesting that bleeding is unpredictable. Reoperation for bleeding occurred in 0.9 per cent (217 of 24 700) of hemithyroidectomies, with male sex, increasing age, decreasing surgeon volume and redo surgery being risk factors. The mortality rate following thyroidectomy was 0.1 per cent (23 of 38 740). In a multivariable model including reoperation for bleeding node dissection and age were significant risk factors for mortality. Conclusion The highest risk for bleeding occurred following total thyroidectomy in men, but overall bleeding was unpredictable. In hemithyroidectomy increasing surgeon thyroidectomy volume reduces bleeding risk. This analysis supports the revised BAETS recommendation to restrict day-case thyroid surgery to hemithyroidectomy performed by high-volume surgeons, with caution in the elderly, men, patients with retrosternal goitres, and those undergoing redo surgery.

We aimed to evaluate the role of pretreatment carcinoembryonic antigen (CEA) and platelet to lymphocyte ratio (PLR) in predicting brain metastasis after radical surgery for lung adenocarcinoma patients. The records of 103 patients with completely resected lung adenocarcinoma between 2013 and 2014 were reviewed. Clinicopathologic characteristics of these patients were assessed in the Cox proportional hazards regression model. Brain metastasis occurred in 12 patients (11.6%). On univariate analysis, N2 stage (P = 0.013), stage III (P = 0.016), increased CEA level (P = 0.006), and higher PLR value (P = 0.020) before treatment were associated with an increased risk of developing brain metastasis. In multivariate model analysis, CEA above 5.2 ng/mL (P = 0.014) and PLR ≥ 120 (P = 0.036) remained as the risk factors for brain metastasis. The combination of CEA and PLR was superior to CEA or PLR alone in predicting brain metastasis according to the receiver operating characteristic (ROC) curve analysis (area under ROC curve, AUC 0.872 versus 0.784 versus 0.704). Pretreatment CEA and PLR are independent and significant risk factors for occurrence of brain metastasis in resected lung adenocarcinoma patients. Combining these two factors may improve the predictability of brain metastasis.

Background: The prevalence of non-communicable diseases is rising in Dhaka City, Bangladesh. Obesity is one of the significant risk factors for many non-communicable diseases. This research aimed to investigate the current prevalence of overweight and obesity among children in selected schools in Dhaka City through anthropometric evaluation, as well as to assess the correlation of various environmental determinants such as physical activity, dietary behavior, lifestyle habits, are associated with increased risk of obesity in children.Methods: This school-based cross-sectional study was conducted among 106 participants (50 male and 56 female participants) aged 6-14 years selected by convenience sampling from four randomly selected primary schools of different regions of Dhaka city. A pre-tested questionnaire was used to collect data.Results: The prevalence of overweight and obesity among school-going children 24.5%, 68% respectively. Factors associated with being obese included type of game (χ2=34.036; p=0.001), total playtime (χ2=17.788; p=0.000), TV and computer watch time (χ2=27.321; p=0.007), spend money to buy fast food (χ2=26.451; p=0.002), eating days fast food in a week (χ2=24.825; p=0.003), type of tiffin (χ2=19.757; p=0.072).Conclusions: Less playtime, longer watching TV and computer, and eating more fast food are major risk factors for overweight and obesity among school-going children in Dhaka city. Interventions are needed to increase awareness of child overweight weight and obesity risk factors to decrease the prevalence of overweight and obesity.

Purpose: Chronic low back pain (LBP) is one of the main causes of disability in the community. Although there have been studies suggesting an association between smoking and LBP, these studies were limited by the small numbers of patients, and they did not control for confounders. The objective of this study was to determine whether cigarette smoking is associated with an increased risk of chronic LBP among adults. Methods: Using Canadian Community Health Survey (cycle 3.1) data, 73,507 Canadians aged 20 to 59 yr were identified. Self-reported chronic LBP status, smoking habits, sex, age, height, weight, level of activity and level of education were identified as well. Back pain secondary to fibromyalgia was excluded. Multivariate logistic regression analysis was used to detect effect modification and to adjust for covariates. Design effects associated with complex survey design were taken into consideration. Results: The prevalence of chronic LBP was 23.3% in daily smokers and only 15.7% in non-smokers. Age and sex were found to be effect modifiers (P < 0.0001), and the relationship between smoking and chronic LBP risk was dependent on sex and age. The association between daily smoking and the risk of chronic LBP was stronger among younger individuals. Occasional smoking slightly increased the odds of having chronic LBP. Conclusion: Daily smoking increases the risk of LBP among young adults, and this effect seems to be dose-dependent. Back pain treatment programs may benefit from integrating smoking habit modification. Further research is required to develop effective prevention strategies.

BACKGROUND: Few studies have investigated the factors associated with asthma in young Aboriginal children.OBJECTIVE: To characterize the association of demographic, environmental and early life factors with asthma in young Aboriginal children in Canada.METHODS: The 2006 Aboriginal Children’s Survey was conducted among off-reserve Aboriginal children zero to six years of age to obtain information on Aboriginal children’s development and well-being. The prevalence of asthma in Aboriginal children was obtained from the parental report of asthma as diagnosed by a health care professional.RESULTS: The prevalence of reported asthma among off-reserve Aboriginal children zero to six years of age (n=14,170) was 9.4%. Asthma prevalence in both exclusively breastfed children (6.8%) and ever but not exclusively breastfed children (9.0%) was significantly lower than that in nonbreastfed children (11.0%). In the multiple logistic regression analysis, exclusive breastfeeding was protective of asthma compared with nonbreastfeeding (OR 0.59 [95% CI 0.44 to 0.78]). Older age groups, male sex, having two or more older siblings, low birth weight, day care attendance and ear infection were significant risk factors for asthma.CONCLUSIONS: The prevalence of asthma among young Aboriginal children zero to six years of age living off reserve was slightly lower than that reported for all other Canadian children. Breastfeeding, especially exclusively breastfeeding, was protective of asthma in Aboriginal children, which is consistent with what has been observed in non-Aboriginal children in Canada. Public health interventions intended for reducing asthma incidence in young Aboriginal children should include breastfeeding promotion programs.

AbstractPrimary graft dysfunction (PGD) is a form of acute lung injury after transplantation characterized by hypoxemia and the development of alveolar infiltrates on chest radiograph that occurs within 72 hours of reperfusion. PGD is among the most common early complications following lung transplantation and significantly contributes to increased short-term morbidity and mortality. In addition, severe PGD has been associated with higher 90-day and 1-year mortality rates compared with absent or less severe PGD and is a significant risk factor for the subsequent development of chronic lung allograft dysfunction. The International Society for Heart and Lung Transplantation released updated consensus guidelines in 2017, defining grade 3 PGD, the most severe form, by the presence of alveolar infiltrates and a ratio of PaO2:FiO2 less than 200. Multiple donor-related, recipient-related, and perioperative risk factors for PGD have been identified, many of which are potentially modifiable. Consistently identified risk factors include donor tobacco and alcohol use; increased recipient body mass index; recipient history of pulmonary hypertension, sarcoidosis, or pulmonary fibrosis; single lung transplantation; and use of cardiopulmonary bypass, among others. Several cellular pathways have been implicated in the pathogenesis of PGD, thus presenting several possible therapeutic targets for preventing and treating PGD. Notably, use of ex vivo lung perfusion (EVLP) has become more widespread and offers a potential platform to safely investigate novel PGD treatments while expanding the lung donor pool. Even in the presence of significantly prolonged ischemic times, EVLP has not been associated with an increased risk for PGD.

Background: Psoriasis is a chronic immune-mediated inflammatory disorder that affects approximately 2% to 3% of the population, which translates to 17 million in North America and Europe and approximately 170 million people worldwide. Although psoriasis can occur at any age, most cases develop before age 40 years. Some larger studies have noted bimodal age at onset with the first peak occurring at approximately age 30 years and the second peak at around 55 to 60 years, but most patients have a younger age of onset (15-30 years). Psoriasis is associated with multiple comorbidities, decreased quality of life, and decreased longevity of life. Two recent systematic reviews and a meta-analysis concluded that psoriasis patients are at increased risk of major adverse cardiovascular events. Multiple studies confirm that many of the comorbidities found in patients with psoriasis are also important risk factors for cardiovascular disease, stroke, diabetes mellitus, hypertension, hyperlipidemia, obesity, and metabolic syndrome. Methods: We conducted a retrospective cohort study using charts from a dermatology clinic combined with an administrative database of patients with moderate to severe psoriasis in Newfoundland and Labrador, Canada. We examined the role of clinical predictors (age of onset of psoriasis, age, sex, biologic use) in predicting incident myocardial infarction (MI). Results: Logistic regression revealed that age of onset (odds ratio [OR], 8.85; P = .005), advancing age (OR, 1.07; P < .0001), and being male (OR, 3.64; P = .018) were significant risk factors for the development of MI. Neither biologic therapy nor duration of biologic therapy were statistically significant risk factors for the development of MI. Our study found that in patients with psoriasis treated with biologics, there was a nonsignificant trend in reduced MI by 78% (relative risk, 0.18; 95% confidence interval, 0.24-1.34; P = .056). Conclusion: Our study demonstrated a trend toward decreased MI in patients with moderate to severe psoriasis on biologics. Patients with an early age of onset of psoriasis (<25 years) were nearly 9 times more likely to have an MI. Clinicians should consider appropriate cardiovascular risk reduction strategies in patients with psoriasis.
