ABSTRACT
Objective To monitor the change patterns of the endemic situation of schistosomiasis in Tianmen City from 2015 to 2018, so as to provide the evidence for formulating the schistosomiasis control strategy in the city. Methods A total of 8 schistosomiasis surveillance sites were assigned in Tianmen City from 2015 to 2018, and the endemic situation of schistosomiasis and the related epidemiological factors were monitored. Results During the period from 2015 to 2018, a total of 15 983 local person-times and 3 629 mobile populations were detected for schistosomiasis using an indirect hemagglutination test (IHA) in Tianmen City, and the sero-prevalence was 0.88% to 1.44% and 0.96% to 2.39%, respectively; however, no egg-positives were identified. A total of 1 245 herd-times were detected, and no egg-positives were found in bovines. In addition, the areas of snail habitats were 116.69 to 117.23 hm2 and the mean densities of living snails were 0.07 to 0.17 snails/0.1 m2 during the study period; however, no infections were identified in snails. Conclusions The endemic situation of schistosomiasis appears low in Tianmen City; however, the factors related to schistosomiasis transmission remain in the city. The integrated strategy with emphasis on the control of infectious sources should be still intensified to consolidate the schistosomiasis control achievements.
ABSTRACT
Hip trauma has been a leading cause of death in senile patients for more than a centenary. Although the mortality decreased due to the advanced technique in medication, surgery and nursing, the increasing mortality should not be neglected in elders after orthopedic operation nowadays. Many factors are considered to influence the causes of death after trauma, such as age, gender, personal customs, comorbidities, types of fracture, timing of surgery, procedure, anesthesia, complications, medical treatment, activity of daily living, or even marriage status. This article reviews these causes from the aspects of patient's own factors, iatrogenic factors, medical treatment and other factors and provides some clues for further clinical application according to the recent foreign and domestic researches. According to the present research, it is essential for surgeons to perform a comprehensive estimation for patients suffering from hip trauma.
