To address childhood obesity, it is important to help children make better choices with regards to intake of sugary drinks and snacks. The purpose of this study was to evaluate the validity of a novel educational intervention designed to convert grams of sugar into teaspoons on labeled beverages. A convenience sample of children （n = 21） at a charter elementary school in Washington, D. C was studied. A pre-test required an estimation of teaspoons of sugar on labels, followed by a practice demonstration and song. A post-test was given requiring estimation of teaspoons of sugar in on the same labels. Two weeks later, a retention test as well as qualitative questions assessed participant learning and information usage. Test scores revealed increased accuracy from pre-test （26.2%） to post-test （79.8%）. Estimations were more accurate after the demonstration, as evidenced by the decreased range in average variation of responses （＋25.6 tsp to ＋1.8 tsp）. Two-week recall maintained accuracy （66.7%）, with an average variance of ＋3.8 teaspoons. Qualitative responses revealed participants had learned and used the conversion concepts. These results suggest that the educational intervention was effective. Qualitative data suggest behavior change, increased awareness, and the potential for change extending to caregivers.

A CFD–DEM study of the behaviour of single-solid and binary mixtures in a pyramidal spouted bed

Particuology 2019年第1期17卷 79-91页

We simulated a lab-scale cold-flow spouted bed through computational fluid dynamics (CFD), coupled with the discrete element method (DEM) for the solid phase, using a commercial CFD program, ANSYS FLUENT 18.0. To limit the computational expense, we tested both a simplified pseudo-2D geometry and a complete 3D geometry. We found that the Haider and Levenspiel drag model is suitable for the pseudo-2D geometry;however, this model does not correctly predict fluidisation in the 3D geometry. Conversely, the Gidaspow drag model behaves accurately in the 3D geometry but overestimates the motion of particles in the pseudo-2D geometry. We studied several single-solid and binary mixtures to assess the reproducibility of segregation phenomena. The pseudo-2D model was able to predict the onset and minimum spouting flow rates of all mixtures with good accuracy. An analysis of the volume fraction contours of the binary mixtures permitted us to confirm that segregation phenomena were correctly predicted at low gas velocities. We showed that segregation decreased as the inlet gas flow rate was increased. Calculations performed in the complete 3D geometry were preliminarily assessed as more reliable but required almost four times as much computational time as those for the pseudo 2D geometry.

Risk stratification for malignant progression in Barrett's esophagus: Gender, age, duration and year of surveillance

AIM To clarify risk based upon segment length, diagnostic histological findings, patient age and year of surveillance, duration of surveillance and *** Patients registered with the United Kingdom Barrett's Oesophagus Registry from 9 United Kingdom centers were included. The outcome measures were(1) development of all grades of dysplasia;(2) development of high-grade of dysplasia or adenocarcinoma; and(3) development of adenocarcinoma. Prevalent cases and subjects with < 1 year of follow-up were excluded. The covariates examined were segment length, previous biopsy findings, age at surveillance, duration of surveillance, year of surveillance and *** One thousand and one hundred thirty six patients were included(total 6474 patient-years). Fifty-four patients developed adenocarcinoma(0.83% per annum), 70 developed high-grade dysplasia/adenocarcinoma(1.1% per annum) and 190 developed any grade of dysplasia(3.5% per annum). High grade dysplasia and adenocarcinoma increased with age and duration of surveillance. The risk of low-grade dysplasia development was not dependent on age at surveillance. Segment length and previous biopsy findings were also significant factors for development of dysplasia and *** The risk of development of low-grade dysplasia is independent of age at surveillance, but high-grade dysplasia and adenocarcinoma were more commonly found at older age. Segment length and previous biopsy findings are also markers of risk. This study did not demonstrate stabilisation of the metaplastic segment with prolonged surveillance.

The need for preventive and curative services for malaria when the military is deployed in endemic overseas territories: a case study and lessons learned

Background: Sri Lanka has been free from indigenous malaria since November 2012 and received the WHO certificate for malaria-free status in September 2016. Due to increased global travel, imported malaria cases continue to be reported in the country. Military personnel returning home from international peace-keeping missions in malaria endemic countries represent a key risk group in terms of imported malaria. The present study intended to characterize the potential causes of a malaria outbreak among the Sri Lankan security forces personnel deployed in the Central African Republic(CAR).Methods: Data were collected from a cross-sectional survey distributed among Sri Lankan Air Force personnel who had returned from United Nations peace-keeping missions in the CAR region. A pre-tested questionnaire was used for the data collection, and focus group discussions were also ***: One hundred twenty male Air Force personnel were interviewed(out of a group of 122 officers and airmen). All participants were deployed in the CAR for 14 months and were aware of the existence of chemoprophylaxis against malaria. The majority of the subjects(92.5%, 111/120) also knew that prophylaxis should be started prior to departure. However, the regular use of chemoprophylaxis was reported by only 61.7%(74/120) of the sample. Overall, 30.8% of the participants(37/120) had 44 symptomatic episodes of malaria during deployment, and one person succumbed to severe malaria. All cases were associated with noncompliance with ***: Better coordination with overseas healthcare services and the establishment of directly observed chemoprophylaxis may help to avoid similar outbreaks in the future.

Pentoxifylline(PTX)is reported to provide beneficial outcomes in the treatment of neonatal sepsis and serious inflammatory conditions.1,2 In the neonatal intensive care setting,PTX is administered by intravenous(IV)infusion and is routinely co-administered via Ysite with other parenteral medications and/or *** the physicochemical compatibility of PTX with a range of parenteral drugs,IV fluids,and lipid-free parenteral nutrition solutions has been reported,there is an emerging demand for more PTX compatibility data against previously untested medications(ampicillin,cloxacillin,fentanyl,fluconazole,furosemide,hydrocortisone,and ibuprofen lysine)and high-concentration IV drugs(alprostadil,dopamine,epinephrine,midazolam,milrinone,morphine,and norepinephrine)which may be used in fluid-restricted,vulnerable patients.3–5 In order to address this requirement for contemporary information,we investigated the physical and chemical compatibility of PTX with a panel of 20 drugs,in 51 PTX-drug combinations.
