A Campylobacteriosis Outbreak Caused by One Asymptomatic Food Handler Carrier.

In August 2021, three students with diarrhea from the same school visited a local hospital in the S district of Beijing. An epidemic investigation showed that there were more students with diarrhea in the same school and they had one meal together. Campylobacter jejuni was isolated from both patients with diarrhea and asymptomatic food handlers; however, the latter also carried Campylobacter coli. Phylogenomic analysis showed that there was a campylobacteriosis outbreak among the students, and the asymptomatic food handler may have been the source of the infection. Routine inspection and surveillance for Campylobacter is needed for the food producing staff, particularly those cooking in the cafeteria in schools or other public food services.

Survey and coping strategies for job stress of new nurses in pharmacy intravenous admixture service: a pilot study.

To survey the nurse stress and analyze stressors in new nurses from pharmacy intravenous admixture service (PIAS). A questionnaire survey referring to the revised stressor scale was carried out on 52 new nurses of PIAS in four hospitals in Harbin. The average stress score for all participants was 2.43±0.63, as medium level of stress. The stressors were classified into 6 categories: ensuring up-to-date knowledge of professional nursing skills, increased workload and work-time, interpersonal relationship, ensuring knowledge of equipments, attending educational programs, and decreased occupational demand. The most important stressors included fear of medical accident occurrence, fear of failure in performance assessment, fear of occupational injuries, feeling fatigue and lack of sleep. Considering the various kinds of stressors in the working places, it was necessary for managers' to use appropriate strategies to cope with the job stress in new nurses of PIAS.

[Analysis of measles immunity level in persistent populations in Beijing, 2012].

OBJECTIVE: To analyze the measles immunity level of persistent population in Beijing. METHODS: A total of 2125 objects from 10 age groups, who had been living in Beijing for over 6 months, were selected from urban and rural areas in Beijing in 2012. Demographic characteristics, history of measles and vaccine immunization were investigated by questionnaire. 5 ml blood sample of each subject was collected, and the Measles IgG antibody was measured by ELISA assay. RESULTS: Positive rate of measles antibody was 84.71% (1800/2125) and standardized positive rate was 88.07% . Median of antibody was 960.46 IU/L. Positive rate and median of measles antibody were significantly different between population from different age groups (χ(2) = 341.60, P < 0.01; H = 216.27, P < 0.01). Antibody positive rate and median were lowest in the <1 year age group, which were separately 43.06% (90/209) and 185.80 IU/L; and highest in the 1-4 (97.31% (181/186) and 2448.81 IU/L) and 5-9 years age group (96.46% (218/226) and 1910.72 IU/L). The range of antibody positive rate and median in adults of ≥ 15 years were 81.98%-90.14% and 744.38-1474.84 IU/L. Antibody positive rate and median in persistent population, which were separately 82.45% (883/1071) and 899.82 IU/L, were lower than those in migrant population, which were 87.00% (917/1054) and 166.19 IU/L, respectively (χ(2) = 8.51, P < 0.01;U = 538 704.00, P < 0.01). Antibody positive rate and median in population with vaccination history, which were separately 91.95% (891/969) and 1443.11 IU/L, were higher than those population without vaccination history and people whose history unknown (32.95% (57/173) , 127.33 IU/L; 86.67% (852/983) , 923.73 IU/L). The difference showed statistical significance (χ(2) = 399.92, P < 0.01; H = 202.11, P < 0.01). CONCLUSION: Among the persistent population in China, measles antibody level among the children aging 1-9 years old was high enough to prevent outbreak and epidemic of measles. However, we should try our best to strengthen the measles antibody level among the babies younger than 1 year old and the migrant population aging between 15 and 40 years old.

[Application of damage control orthopaedic for the treatment of comminuted fractures of superior tibia in complex injury].

OBJECTIVE: To investigate the treatment of comminuted superior tibial fracture in complex injury according to damage control orthopaedic. METHODS: From Jan. 2007 to Jun. 2009,11 patients suffered from comminuted superior tibial fracture with complex injury, including 8 males and 3 females with an average age of 35.2 years. The external fixator were used to fix tibial fracture in emergency treatment, after 6 weeks when the condition of patients were improved, fix the external tibia by LISS plate through litter incision, fix interior tibia by reconstructed plate or sustained plate. The effect evaluated by Lysholm standard, marking system on the basis of limp, walking stick, angina, knee unsteady, pain, swell, up and down floor, squat. RESULTS: All the postoperative CR showed that the superior tibial fractures were acquired functional reduction, the incision got well and no infection occurred. All 11 patients were followed-up for 12 to 18 months with an average of 14.7 months. According to an evaluation standard of Lysholm, the results were excellent in 5 cases, good in 4 cases, fair in 1 case, poor in 1 case. CONCLUSION: According to damage control orthopaedic, the treatment of comminuted superior tibial fracture by external fixation and LISS plate is a suitable method for the patient with complex injury who undergo comminuted superior tibial fracture.
