Abstract Background On September 4, 2018, a boarding school in the Shunyi District of Beijing, China reported an outbreak of acute gastroenteritis. At least 209 suspected students caused of diarrhea and vomiting. The case was investigated, and control measures were taken to prevent further spread. Methods A retrospective cohort study was conducted among the school students and staff in order to test hypothesis that high risk of food served at the school canteen. We collected information on demographics, refectory records, person to person transmission by uniform epidemiological questionnaire. Risk ratios (RR) and 95% confidence intervals (CI) were calculated. Stool specimens of cases and canteen employees, retained food, water, and environmental swabs were investigated by laboratory analysis. Results We identified 209 cases (including 28 laboratory-confirmed cases) which occurred from August 29 to September 10. All cases were students, and the average age was 20, 52% were male. The outbreak lasted for 13 days, and peaked on September 5. Consumption of Drinks stall and Rice flour stall on September 1 (RR:3.4, 95%CI:1.5–7.8, and RR:7.6, 95%CI:2.8–20.2), Rice flour stall and Fish meal stall on September 2 (RR:4.0, 95%CI:1.2–13.6, and RR:4.6, 95%CI:1.7–12.5), muslim meal stall on September 4 (RR:2.7, 95%CI:1.3–5.4), Barbeque stall on September 5 (RR:3.0, 95%CI:1.2–7.0) were independently associated with increased risk of disease within the following 2 days. Among 35 specimens of rectal swabs or feces from students, 28 specimens were positive. Norovirus GI.6 alone was detected in 23 specimens, Bacillus cereus alone in 3 specimens and both norovirus GI.6 and Bacillus cereus in 2 specimens. Ten specimens of rectal swabs from canteen employees were positive for norovirus GI, and 2 specimens were positive for Bacillus cereus. Four retained food specimens were positive for Bacillus cereus, and environmental samples were negative for any viruses or bacteria. Conclusion Our investigation indicated that canteen employees were infected by two pathogens (norovirus and Bacillus cereus) and transmission may have been possible due to unhygienic practices. Student consumption of food or drink at high-risk stalls was determined as the probable cause of the outbreak.

Abstract Background Perioperative anesthetic management may affect long-term outcome after cancer surgery. This study aimed to investigate the effect of perioperative glucocorticoids on long-term survival in patients after radical resection for pancreatic cancer.Methods In this retrospective cohort study, patients who underwent radical resection for pancreatic cancer from January 2005 to December 2016 were recruited. Baseline and perioperative data including use of glucocorticoids for prevention of postoperative nausea and vomiting were collected. Patients were followed up for tumor recurrence and survival. The primary outcome was the overall survival (OS); the secondary outcome was the recurrence-free survival (RFS). A multivariable Cox proportional hazard model was used to analyze the influence of perioperative glucocorticoid use on OS and RFS after correction for confounding factors.Results A total of 215 patients after radical surgery for pancreatic cancer were included in the study; of these, 112 received perioperative glucocorticoids and 103 did not. Patients were followed up for a median of 74.0 months (95% confidence interval [CI] 68.3-79.7). Both OS and RFS were significantly longer in patients with glucocorticoids than in those without (for OS: median 19.7 months [95% CI 12.3-36.2] vs. 13.9 months [8.0-23.9], P=0.001; for RFS: 12.0 months [6.0-28.0] vs. 6.9 months [4.2-17.0], P=0.002). After correction for confounding factors, perioperative glucocorticoids were significantly associated with prolonged OS (HR 0.692, 95% CI 0.499-0.959, P=0.027) and RFS (HR 0.634, 95% CI 0.459-0.878, P=0.006).Conclusions Perioperative use of low-dose glucocorticoids may improve long-term survival in patients undergoing radical surgery for pancreatic cancer.
