ABSTRACT
Objective To understand the infection status and the main risk factors of soil-transmitted nematodes in children in the poverty-stricken areas of Guizhou Province and Sichuan Province,so as to provide the evidences for making suitable control strategies in these areas. Methods A total of 95 villages and 6 primary schools in 6 poor counties in the two provinces were select-ed as investigation sites according to the stratified random sampling method. Eleven preschool children aged 3-5 years in each sam-ple village and 11 school children aged 8-10 years in each sample school were chose as investigation objectives,their feces were collected and examined by Kato-Katz technique. In addition,the village doctor and cadres in each village were investigated by a standardized questionnaire to understand the deworming condition of children and the social economy and sanitary status in 2009. Then the correlation between average soil-transmitted nematode infection rate and its influencing factors was analyzed by the Tobit model. Results A total of 1 707 children from 95 villages in the two provinces were examined. In Guizhou Province,the total in-fection rate of soil-transmitted nematodes in children was 46.1%,and the infection rates of Ascaris lumbricoides,Hookworm,and Trichuris trichiura were 31.1%,4.1% and 10.8% respectively,and the corresponding rates in Sichuan Provinces were 9.8%, 3.6%,3.5%,2.7%,respectively. In the dimension of school,a total of 890 school-aged kids from 46 schools in the two provinces were examined,the infection rates of soil-transmitted nematodes,Ascaris lumbricoides,Hookworm,and Trichuris trichiura in Guizhou Province were 53.8%,32.7%,6.6% and 14.4%,respectively,and the corresponding rates in Sichuan Province were 7.3%,2.2%,2.9% and 2.2%,respectively. The results from Tobit analysis indicated that the proportion of children accepted deworming treatment and the paddy field in the cultivated area were statistically correlated to the infections of soil-transmitted nematodes and Ascaris lumbricoides(all P < 0.05). Conclusions The soil-transmitted nematode infection rates of children are still at a high level in poor areas of southwest China. In order to decrease the infection rates,besides the long-term deworming, water supply and sanitary improvement,and the health education should be strengthened,and the treatment of soil-transmitted nematodes should be covered by the New Rural Cooperative Medical System.
ABSTRACT
OBJECTIVE@#To evaluate the condition of cancer-related fatigue (CRF) in breast cancer patients with chemotherapy and to explore the effect of Yoga on it.@*METHODS@#After the completion of Yoga, 100 breast cancer patients with CRF (CFS>0) were selected and were randomly divided into the Yoga group and the control group (n=50). Patients in the control group only received routine cure and care while patients in the Yoga group received extra Yoga exercise, lasting for 4 months. Cancer fatigue scale (CFS) was evaluated in the 2nd, 4th and 6th round of chemotherapy.@*RESULTS@#At the end, 82 cases qualified for the study, 42 cases for the control group and 40 for the Yoga group. The mean score of body fatigue was 12.67±3.46. There was no significant difference in CRF between the Yago group and the control group before the Yoga intervention (P>0.05). After the 4th round of chemotherapy, the mean scores of CFS and body fatigue in the Yoga group were significantly lower than that in the control group (P<0.05). After the 6th round of chemotherapy, the mean scores of CFS, body fatigue and cognitive fatigue in the Yoga group were lower than that in the control group (P<0.05). Repeated analysis of variance showed that the difference in the overall fatigue, body fatigue and cognitive fatigue between the Yoga group and the control group was significant (P<0.05); the time influence on the overall fatigue, body fatigue and emotional fatigue was significant difference between the 2 groups (P<0.05); there were interactions between the effect of Yago and time on the overall fatigue, body fatigue and cognitive fatigue (P<0.05).@*CONCLUSION@#The body fatigue was more serious in breast cancer patients with chemotherapy. Yoga intervention could significantly reduce body fatigue, cognitive fatigue, thus reduce the overall fatigue in breast cancer patients with chemotherapy.
