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.

The Impact

Nutritional status is relevant to functional recovery in patients after an acute process requiring rehabilitation. Nevertheless, little is known about the impact of malnutrition on geriatric rehabilitation. This study aimed to determine the association between nutritional status at admission and the evolution of functional and physical outcomes, as well as the capability of nutritional status to identify fallers among patients admitted to geriatric rehabilitation for different reasons. This was a retrospective cohort study of 375 patients. Data collected included age, gender, diagnosis at admission, comorbidities, cognitive and nutritional status, functional and physical measurements, length of stay, mortality and falls. Orthogeriatric patients with worse nutritional status according to the Mini Nutritional Assessment-Short Form (MNA-SF) had a significantly lower Barthel Index at admission and discharge with worse functional gain and poorer outcomes in the Short Physical Performance Battery (SPPB). However, in hospital-deconditioned patients, the MNA-SF score was not significantly associated with functional and physical recovery. Poor nutritional status at admission increased the risk of experiencing at least one fall during rehabilitation in orthogeriatric patients. However, hospital-deconditioned patients who fell had better SPPB scores than those who did not fall. Our results demonstrate the importance of nutritional status in the clinical evolution of orthogeriatric patients throughout the rehabilitation process.

Abstract Background Managing children with minor head trauma remains challenging for physicians who evaluate for the need for computed tomography (CT) imaging for clinically important traumatic brain injury (ciTBI) identification. The Pediatric Emergency Care Applied Research Network (PECARN) prediction rules were adopted in our pediatric emergency department (PED) in December 2013 to identify children at low risk for ciTBI. This study aimed to evaluate this implementation’s impact on CT rates and clinical outcomes. Methods Retrospective cohort study on pediatric patients with head trauma presenting to the PED of the American University of Beirut Medical Center in Lebanon. Participants were divided into pre- (December 2012 to December 2013) and post-PECARN (January 2014 to December 2016) groups. Patients were further divided into < 2 and ≥ 2 years and stratified into groups of low, intermediate and high risk for ciTBI. Bivariate analysis was conducted to determine differences between both groups. Results We included 1362 children of which 425 (31.2%) presented pre- and 937 (68.8%) presented post-PECARN rules implementation with 1090 (80.0%) of low, 214 (15.7%) of intermediate and 58 (4.3%) of high risk for ciTBI. CTs were ordered on 92 (21.6%) pre- versus 174 (18.6%) patients post-PECARN (p = 0.18). Among patients < 2 years, CT rates significantly decreased from 25.2% (34/135) to 16.5% (51/309) post-PECARN (p = 0.03), and dropped in all risk groups but only significantly for low risk patients from 20.7% (24/116) to 11.4% (30/264) (p = 0.02). There was no significant decrease in CT rates in patients ≥2 years (20% pre (58/290) vs 19.6% post (123/628), p = 0.88). There was no increase in bounce back numbers, nor in admission rates or positive CT findings among bounce backs. Conclusions PECARN rules implementation did not significantly change the overall CT scan rate but reduced the CT scan rate in patients aged < 2 years at low risk of ciTBI. The implementation did not increase the number of missed ciTBI.

e15147 Background: Androgen deprivation therapy (ADT) is the cornerstone treatment of advanced PC, but is frequently used in the M0 setting. After a variable period of hormone-sensitivity, most patients develop CR disease (rising prostate-specific antigen [PSA] despite ongoing ADT). These men are at increased risk of developing bone metastases (BMT), particularly in those with higher serum PSA and shorter PSA doubling time (DT). The epidemiology and natural history of M0 CRPC has not been well-studied in a population-based setting. Methods: A retrospective cohort study was conducted using HFHS administrative data and included 691 men diagnosed with M0 PC between 1996 and 2005, who received ADT, with serial PSA measurements to determine CR. Patient records through 12/31/2008 were reviewed for outcomes of interest. CRPC was defined as 2 consecutive PSA rises, with “high risk” defined as PSA ≥8 ng/mL or PSA DT ≤10 months (mos) after the development of CRPC (Smith MR et al. Lancet 379:39-46, 2012). The risk of BMT was estimated for the entire cohort and for the CRPC and high-risk CRPC subsets. Results: Of the 691 patients included in the cohort (median age: 73 years, 48% African American), 98% received only GnRH agonists and 2% had orchiectomy. Median follow-up for the entire cohort after ADT initiation was 49 mos (IQR=45). 101 patients (15%) met criteria for CRPC during follow-up, with a median of 18 mos on active ADT prior to CRPC development (IQR=14). Of CRPC patients, 85% met criteria for high-risk (of those, 16% had PSA ≥8 ng/mL, 12% had PSA DT ≤10 mos, and 72% had both). Among all patients, 12% (n=82) developed BMT during follow-up, with 42% (n=36) of the high-risk CRPC subset developing BMT. Median time from high-risk CRPC to BMT was 9 mos (IQR=17). Conclusions: The HFHS resource allowed for our investigation of PSA characteristics corresponding to disease progression in a racially diverse patient population. A substantial proportion of M0 PC patients on ADT will eventually develop CR disease. Once a patient has CRPC, the risk of BMT is relatively high.
