A small animal veterinarian in Washington State developed leptospirosis after an occupational exposure. Approximately 10 days prior to the onset of illness, he examined a healthy appearing pet rat for fleas, which urinated on his un‐gloved hands. Although the veterinarian washed his hands after the examination, his hands had abrasions from gardening. The veterinarian was hospitalized for 12 days and was able to return to work part‐time 1 month following discharge. This illness may have been prevented if the veterinarian had been wearing gloves during the examination as recommended by the National Association of State Public Health Veterinarians (NASPHV), Veterinary Infection Control Committee, in its Compendium of Veterinary Standard Precautions for Zoonotic Disease Prevention in Veterinary Personnel (2008). This case alerts us to the need for small animal veterinarians to minimize their infection risk by practising recommended infection control procedures. Veterinarians should establish and follow a written infection control plan based on the standardized infection control approach adopted by the NASPHV to minimize their risk of occupational zoonotic infections.  相似文献

The aim of this randomized, double‐blinded, placebo–controlled, cross‐over designed study was to demonstrate the clinical effect, registered by a survey, of a 10‐week period of omega‐3 fatty acid supplementation of the diet (1.53 g eicosapentaenoic acid (EPA) and 0.31 g DHA, both per 1000 kcal ME, equivalent to the complete diet) of 16 cats with radiologically documented, naturally occurring osteoarthritis (OA), in comparison with a 10‐week period of supplementation with corn oil (0.00 g EPA and 0.00 g DHA, both per 1000 kcal ME). Cats on the fish oil revealed higher activity level (p = 0.07), more walking up and down the stairs (p = 0.07), less stiffness during gait (p = 0.03), more interaction with the owner (p = 0.07) and higher jumps (p = 0.03) compared to those on corn oil supplementation. In conclusion, supplementation of long‐chain omega‐3 polyunsaturated fatty acids changes the owner’s perception of some aspects of behaviour and locomotion in cats with naturally occurring OA.  相似文献

Urban parks can bring multiple health benefits to seniors and thus are important to their lives. This study investigated seniors’ spatial distribution, preferred activity zones, and activity intensity during park visits. We used GPS trackers to collect spatial location information and accelerometers to record metabolic equivalent of energy (MET) at an interval of 10 s, and examined differences in activity intensity according to activity zone type. Data from 286 seniors in two large urban parks in Shanghai, China were included. We identified eight park activity zone types: pathway, paved open space, sports area, children’s playground, lawn, water, other natural area, building, and other area. Grid cells of 5 m by 5 m were created and hotspot analysis was utilized to identify the activity zones most frequently used by seniors. ANOVA post-hoc analysis was applied to investigate the variance between activity zone cells in terms of mean visit point counts, total visit point MET, and average MET. We also utilized latent class analysis to identify distinctive subgroups of seniors.The results indicate that seniors’ spatial distributions vary vastly both between and within park activity zones. Of the eight zone types, paved open space was used most frequently, and seniors were most active on pathways. Other natural area also had high usage, and featured higher average activity intensity than sports area, water, and building and other area. Children’s playground had higher average activity intensity than lawn or water. Finally, three distinctive groups of seniors were identified: short-stay active walker, long-stay light walker, and short-stay transient. These findings have direct implications for park design practice. Paved open space and pathways should be carefully designed based on the specific seniors’ activity patterns. Furthermore, seniors’ needs should be considered in the design of playgrounds in parks, where they accompany their grandchildren, and of other natural area, where they stretch their bodies and enjoy fresh air. The diverse activity patterns of the subgroups of seniors should be addressed in future studies.  相似文献

选用我国上市公司的大样本数据,实证检验公司高层中女性比例的高低对上市公司的盈余质量的影响。结果显示,与国外同类研究的结论不一致,在我国上市公司中,盈余反应系数、稳健性、平滑度以及持续性等各个方面的盈余质量均未因女性高管的作用而存在显著差异。  相似文献
