Background  

Murray Valley encephalitis virus (MVEV) is a mosquito-borne Flavivirus (Flaviviridae: Flavivirus) which is closely related to Japanese encephalitis virus, West Nile virus and St. Louis encephalitis virus. MVEV is enzootic in northern Australia and Papua New Guinea and epizootic in other parts of Australia. Activity of MVEV in Western Australia (WA) is monitored by detection of seroconversions in flocks of sentinel chickens at selected sample sites throughout WA.  相似文献

Objectives

The aim of this study was to investigate the distribution of Shiga toxin (Stx) gene-positive stool samples from dairy farmer and slaughterhouse workers in Gyeonggi-Do province.

Methods

A total of 621 samples from healthy farmers and 198 samples from slaughterhouse workers were screened by polymerase chain reaction (PCR) for Shiga toxigenic Escherichia coli (STEC) infection on stool samples.

Results

The PCR product of Stx-encoding genes was detected in 21 (3.4%) of 621 farmers and 15 (7.6%) of 198 slaughterhouse workers’ stool samples. Distribution of the Stx PCR positive workers by age increment revealed an increase in STEC infection with age increment in both workers. Distribution of the Stx PCR positive workers by working years revealed an increase in STEC infection with working years in farmers.

Conclusion

These results of the study show that slaughterhouse workers are at higher risk of STEC infection than farmers. In addition, slaughterhouse workers have a more potential source of food contamination of STEC and transmission.  相似文献

Background

Attention‐deficit hyperactivity disorder (ADHD) is the most commonly diagnosed behavioural disorder of childhood, affecting 3–5% of school‐age children. The present study investigated whether the supplementation of soy‐derived phosphatidylserine (PS), a naturally occurring phospholipid, improves ADHD symptoms in children.

Methods

Thirty six children, aged 4–14 years, who had not previously received any drug treatment related to ADHD, received placebo (= 17) or 200 mg day–1 PS (= 19) for 2 months in a randomised, double‐blind manner. Main outcome measures included: (i) ADHD symptoms based on DSM‐IV‐TR; (ii) short‐term auditory memory and working memory using the Digit Span Test of the Wechsler Intelligence Scale for Children; and (iii) mental performance to visual stimuli (GO/NO GO task).

Results

PS supplementation resulted in significant improvements in: (i) ADHD (< 0.01), AD (< 0.01) and HD (< 0.01); (ii) short‐term auditory memory (< 0.05); and (iii) inattention (differentiation and reverse differentiation, < 0.05) and inattention and impulsivity (< 0.05). No significant differences were observed in other measurements and in the placebo group. PS was well‐tolerated and showed no adverse effects.

Conclusions

PS significantly improved ADHD symptoms and short‐term auditory memory in children. PS supplementation might be a safe and natural nutritional strategy for improving mental performance in young children suffering from ADHD.  相似文献

Background  

Limited evidence suggests that people from non-English speaking backgrounds in Australia have lower than average rates of participation in cancer screening programs. The objective of this study was to examine the distribution of bowel, breast and prostate cancer test use by place of birth and years since migration in a large population-based cohort study in Australia.  相似文献

Background

Shiga-toxin E. coli infections remain a public health concern because of the severity of the gastrointestinal illness and associated complications. Transmission pathways are typically elucidated from outbreaks, with foodborne transmission the primary source. However, most STEC cases are sporadic. This systematic review aimed to identify the most common pathways for sporadic STEC transmission and quantify their importance.

Methods

We systematically reviewed epidemiological studies of sporadic (non-outbreak) STEC cases that investigated potential risk factors. Searches were run in Medline, EMBASE, and Scopus. Included studies needed to confirm STEC infection and investigate ≥20 cases.

Results

31 studies were included, of which 25 were case-control or case-case studies. 62.5% found consumption of undercooked/raw meat associated with STEC infection while 70.4% found contact with animals or their environment a risk factor. Random-effects meta-analysis provided pooled odds ratios and population attributable fraction (PAF). The PAF was 19% for undercooked/raw meat, followed by person to person transmission at 15%. Contact with animals and visiting farm environments had PAFs of 14% and 12% respectively.

Conclusions

Out of potential sources for STEC exposure, undercooked meat and contact with animals and their environment were the most frequently found transmission routes. Decreasing the chances of acquiring the bacteria by these methods would additionally cut down on the other major transmission route, person-to-person spread.  相似文献

Objective

To describe the outcomes of patients transferred to King Edward Memorial Hospital (KEMH) with signs of labour at preterm gestations.

Design

A retrospective observational study of the 69 cases transferred to KEMH during 2015.

Setting

Patient transfers from all locations across Western Australia (WA) to the sole tertiary perinatal centre in Perth.

Participants

Pregnant women within WA with threatened or actual preterm labour (PTL) or preterm prelabour rupture of membranes (PPROM) between 23 and 32 weeks gestation.

Main outcome measures

The occurrence of delivery during the admission and time‐to‐delivery as well as length of admission and association between clinical factors and time‐to‐delivery.

Results

The percentage of the study population delivered during the admission following transfer was 72.5%. Eighty‐six per cent of those who delivered did so within 72 hours of transfer. The median time from transfer to delivery was 1 day. Sixty‐three per cent of those who did not deliver during the admission progressed to 36 weeks gestation. Patients transferred with PPROM were less likely to deliver during the admission compared to those with uterine activity (50% versus 19.6%, P = 0.007) and nulliparas were more likely to deliver (93.5% versus 55.3%, < 0.001).

Conclusion

The majority of women transferred with signs of PTL progress to delivery during the same admission with the highest risk of delivery being the first 72 hours following transfer. If the pregnancy is ongoing at 72 hours, there is a reasonable chance of progression to late preterm gestation supporting the return of woman to their place of origin for antenatal care following discharge.  相似文献

Background

Baby‐led weaning (BLW) where infants self‐feed family foods during the period that they are introduced to solid foods is growing in popularity. The method may promote healthier eating patterns, although concerns have been raised regarding its safety. The present study therefore explored choking frequency amongst babies who were being introduced to solid foods using a baby‐led or traditional spoon‐fed approach.

Methods

In total, 1151 mothers with an infant aged 4–12 months reported how they introduced solid foods to their infant (following a strict BLW, loose BLW or traditional weaning style) and frequency of spoon‐feeding and puree use (percentage of mealtimes). Mothers recalled if their infant had ever choked and, if so, how many times and on what type of food (smooth puree, lumpy puree, finger food and specific food examples).

Results

In total, 13.6% of infants (n = 155) had ever choked. No significant association was found between weaning style and ever choking, or the frequency of spoon or puree use and ever choking. For infants who had ever choked, infants following a traditional weaning approach experience significantly more choking episodes for finger foods (F2,147 = 4.417, P = 0.014) and lumpy purees (F2,131 = 6.46, P = 0.002) than infants following a strict or loose baby‐led approach.

Conclusions

Baby‐led weaning was not associated with increased risk of choking and the highest frequency of choking on finger foods occurred in those who were given finger foods the least often. However, the limitations of noncausal results, a self‐selecting sample and reliability of recall must be emphasised.  相似文献

Background  

In the Arctic, polar bears (Ursus maritimus) bio-accumulate mercury as they prey on polluted ringed seals (Phoca hispida) and bearded seals (Erignathus barbatus). Studies have shown that polar bears from East Greenland are among the most mercury polluted species in the Arctic. It is unknown whether these levels are toxic to liver and kidney tissue.  相似文献

Background  

Encouraging cycling is an important way to increase physical activity in the community. The Cycling Connecting Communities (CCC) Project is a community-based cycling promotion program that included a range of community engagement and social marketing activities, such as organised bike rides and events, cycling skills courses, the distribution of cycling maps of the area and coverage in the local press. The aim of the study was to assess the effectiveness of this program designed to encourage the use of newly completed off-road cycle paths through south west Sydney, Australia.  相似文献
