Abstract Background The association between influenza vaccination and implantable cardiac defibrillator (ICD) therapies during influenza season is not known and is described in this study. Understanding this association is important since reduction in ICD therapies during influenza season via use of influenza vaccination would benefit patients physically and psychologically. Methods Patients presenting to the Sunnybrook Health Sciences Center ICD clinic between September 1st, 2011 and November 31st, 2011 were asked to complete a survey evaluating their use of the influenza vaccine. The number of patients with any ICD therapy and the total number of ICD therapies in the six months before and the three months during the 2010–2011 influenza season were determined. Poisson regression analysis was employed to assess differences in the average number of ICD therapies received during the influenza season based on vaccine status (vaccinated vs. unvaccinated). The analysis was repeated after limiting the cohort to patients with a left ventricular ejection fraction ≤35%. Results A total of 229 patients completed the survey, 78% of whom received the influenza vaccine. Four patients had more than one ICD shock during the study period. Electrical storm was rare ( n =2). A trend toward more ICD therapies (unadjusted incident rate ratio (IRR)=3.2; P =0.07) and appropriate ICD shocks (unadjusted IRR=9.0; P =0.17) was noted for unvaccinated compared to vaccinated patients. This association persisted when analysis was limited to patients with a left ventricular ejection fraction ≤35% (all ICD therapies: unadjusted IRR=5.8; P =0.045; adjusted IRR=2.6; P =0.33). No patient who received the influenza vaccine, and had a reduced ejection fraction, received an approprite ICD shock during influenza season (unadjusted P <0.002). Conclusion A trend toward more ICD therapies during influenza season was observed in patients who did not receive the influenza vaccine compared to those who did. The association was stronger in patients who received appropriate ICD shocks and in patients with left ventricular systolic dysfunction. Further work to confirm these findings is recommended.

Sugar-sweetened beverages are associated with type 2 diabetes. To assess whether this association holds for the fructose-containing sugars they contain, we conducted a systematic review and meta-analysis of prospective cohort studies. We searched MEDLINE, Embase, CINAHL and the Cochrane Library (through June 2016). We included prospective cohort studies that assessed the relation of fructose-containing sugars with incident type 2 diabetes. Two independent reviewers extracted relevant data and assessed risk of bias. We pooled risk ratios (RRs) using random effects meta-analyses. The overall quality of the evidence was assessed using the Grading of Recommendations Assessment, Development and Evaluation (GRADE) system. Fiffeen prospective cohort studies (251 261 unique participants, 16 416 cases) met the eligibility criteria, comparing the highest intake (median 137, 35.2 and 78 g/d) with the lowest intake (median 65, 9.7 and 25.8 g/d) of total sugars, fructose and sucrose, respectively. Although there was no association of total sugars (RR 0.91, 95% confidence interval [CI] 0.76–1.09) or fructose (RR 1.04, 95% CI 0.84–1.29) with type 2 diabetes, sucrose was associated with a decreased risk of type 2 diabetes (RR 0.89, 95% CI 0.80–0.98). Our confidence in the estimates was limited by evidence of serious inconsistency between studies for total sugars and fructose, and serious imprecision in the pooled estimates for all 3 sugar categories. Current evidence does not allow us to conclude that fructose-containing sugars independent of food form are associated with increased risk of type 2 diabetes. Further research is likely to affect our estimates. ClinicalTrials.gov, no. NCT01608620

Purpose: We conducted a pilot survey among young adults attending a suburban Canadian university to understand: (1) knowledge of the 2019 Canada’s Food Guide (CFG); (2) self-reported food choices and eating habits; (3) perceived influence of the CFG on food choices and eating habits; and (4) suggestions to improve engagement with CFG. Methods: Students were recruited, through posts on social media platforms, to complete an online questionnaire between 7 March and 6 April 2020. Results: One-hundred and twenty-one (70% women) students responded. One-third (33%) of women and 8% of men reported consuming the recommended proportion of vegetables and fruits (i.e., 40%–60% of the plate) at their most recent meal (P = 0.001). Men were more likely to report overconsuming protein foods than women (58% vs 32%, P = 0.005). The perceived influence of the CFG on food choices and eating habits was low, with a mean score 2.2 ± 1.4 out of 7, with 7 indicating “highly influential.” Over 92% of participants believed awareness of the CFG could be improved through social media platforms. Conclusions: Although half of the participants correctly answered all 8 questions that assessed knowledge of the CFG, there is an opportunity for dietitians and related health professionals to improve engagement with CFG.
