Abstract Primary Subject area Emergency Medicine - Paediatric Background Healthcare visits, hospitalizations, and deaths due to opioid-related harms continue to rise for children, despite an overall decline in opioid prescriptions. Decision-makers (including patients and families, clinicians, and policy-makers) require high quality syntheses to inform decisions regarding opioid use. Previous research has found that how systematic review (SR) results are presented may influence uptake by decision-makers. Evidence summaries are appealing to decision-makers as they provide key messages in a succinct manner. Objectives 1) To conduct an SR examining the association between short-term therapeutic exposure to opioids in children and development of opioid use disorder, and 2) To gain perspectives from policy decision-makers on the usability and presentation of results through the form of an evidence summary. Design/Methods We conducted an SR following methods recommended by Cochrane. A medical librarian conducted a comprehensive search and two authors were involved in study selection, data extraction and quality assessment. Studies were eligible if they reported primary research in English or French, and study participants had therapeutic exposure to opioids before age 18 years. Results were described narratively. Decision makers were recruited through purposive and snowball sampling methods, and they participated in interviews to discuss an evidence summary based on the SR. Interviews were transcribed and data were analyzed using content analysis. Ethics approval was obtained for the qualitative study. Results Nineteen American studies involving 47,191,990 participants were included. One study demonstrated that short-term therapeutic exposure may be associated with opioid abuse. Four others showed an association without specifying duration of exposure. Fourteen studies provided information on prevalence or incidence of opioid misuse following therapeutic exposure, median 27.8% [interquartile range 21.4% – 30.7%]; notably, 12 of them did not specify duration of therapeutic exposure. Identified risk factors were contradictory and remain unclear. Decision makers had mixed preferences for the presentation of evidence, depending on their degree of involvement in research versus practice. A majority preferred having methods and key characteristics of studies included in the first page of the evidence summary. They noted that the summary should not be text-heavy and details should be appended. Conclusion A number of studies suggest there is an association between lifetime therapeutic opioid use (unknown duration) and future nonmedical opioid use; however, there is limited evidence to determine whether short-term exposure is specifically associated with these outcomes. Policy and decision-makers prefer a succinct evidence summary for this SR, with study-specific details provided as an appendix. PROSPERO Registration: 122681.

Background: No study has compared the respiratory effects of environmental and occupational particulate exposure in healthy adults. Methods: We estimated, by a systematic review and meta-analysis, the associations between short term exposures to fine particles (PM2.5 and PM4) and certain parameters of lung function (FEV1 and FVC) in healthy adults. Results: In total, 33 and 14 studies were included in the qualitative synthesis and meta-analyses, respectively. In environmental studies, a 10 µg/m3 increase in PM2.5 was associated with an FEV1 reduction of 7.63 mL (95% CI: −10.62 to −4.63 mL). In occupational studies, an increase of 10 µg/m3 in PM4 was associated with an FEV1 reduction of 0.87 mL (95% CI: −1.36 to −0.37 mL). Similar results were observed with FVC. Conclusions: Both occupational and environmental short-term exposures to fine particles are associated with reductions in FEV1 and FVC in healthy adults.

Abstract The relationship between diabetes mellitus and short-term exposure to extreme temperatures remains controversial. A systematic review and meta-analysis were performed to assess the association between extreme temperatures and diabetes mellitus morbidity and mortality. PubMed, Embase, the Cochrane Library, Web of Science and the Cumulative Index to Nursing and Allied Health Literature (CINAHL) were searched since inception to January 1, 2019, and updated on November 17, 2020. The results were combined using random effects model and reported as relative risk (RR) with 95% confidence interval (CI). 32 studies met the included criteria. (1) Both heat and cold exposures have impact on diabetes. (2) For heat exposure, the subgroup analysis revealed that the effect on diabetes mortality (RR = 1.139, 95% CI: 1.089–1.192) was higher than morbidity (RR = 1.012, 95% CI: 1.004–1.019). (3) With the increase of definition threshold, the impact of heat exposure on diabetes rised. (4) A stronger association between heat exposure and diabetes was observed in the elderly (≥ 60 years old) (RR = 1.040, 95% CI: 1.017–1.064). In conclusion, both short-term exposure to heat and cold temperatures have impact on diabetes. The elderly is the vulnerable population of diabetes exposure to heat temperature. Developing definitions of heatwaves at the regional level are suggested.

Abstract Background Decreased heart rate variability (HRV) is a predictor of autonomic system dysfunction, and is considered as a potential mechanism of increased risk of cardiovascular disease (CVD) induced by exposure to particulate matter less than 2.5 μm in diameter (PM2.5). Previous studies have suggested that exposure to PM2.5 may lead to decreased HRV levels, but the results remain inconsistent. Methods An updated systematic review and meta-analysis of panel studies till November 1, 2019 was conducted to evaluate the acute effect of exposure to ambient PM2.5 on HRV. We searched electronic databases (PubMed, Web of Science, and Embase) to identify panel studies reporting the associations between exposure to PM2.5 and the four indicators of HRV (standard deviation of all normal-to-normal intervals (SDNN), root mean square of successive differences in adjacent normal-to-normal intervals (rMSSD), high frequency power (HF), and low frequency power (LF)). Random-effects model was used to calculate the pooled effect estimates. Results A total of 33 panel studies were included in our meta-analysis, with 16 studies conducted in North America, 12 studies in Asia, and 5 studies in Europe. The pooled results showed a 10 μg/m3 increase in PM2.5 exposure which was significantly associated with a − 0.92% change in SDNN (95% confidence intervals (95%CI) − 1.26%, − 0.59%), − 1.47% change in rMSSD (95%CI − 2.17%, − 0.77%), − 2.17% change in HF (95%CI − 3.24%, − 1.10%), and − 1.52% change in LF (95%CI − 2.50%, − 0.54%), respectively. Overall, subgroup analysis suggested that short-term exposure to PM2.5 was associated with lower HRV levels in Asians, healthy population, and those aged ≥ 40 years. Conclusion Short-term exposure to PM2.5 was associated with decreased HRV levels. Future studies are warranted to clarity the exact mechanism of exposure to PM2.5 on the cardiovascular system through disturbance of autonomic nervous function.
