ABSTRACT
Objective To assess the prevalence of blood donation and associated factors in men who have sex with men (MSM) in China.Methods Our observational study was conducted between January and August,2017 in 3 cities:Guangzhou,Shenzhen and Wuxi.Eligible participants were MSM (≥ 18 years old) who had either ≥2 male sex partners or unprotected anal sex with casual partners,or had been diagnosed with STI in the past 6 months.A self-completed tablet-based questionnaire was used to collect the information about MSM's socio-demographic characteristics,sexual behaviors and blood donation history.Results A total of 603 MSM were enrolled in our study,including 302 in Guangzhou,152 in Shenzhen and 149 in Wuxi,with a mean age of 27.9 years (SD=7.8).Overall,29.2％ (176/603) of the MSM reported a history of blood donation,and 33.1％ (100/302) in Guangzhou,27.6％ (42/152) in Shenzhen and 22.8％ (34/149) in Wuxi,the differences were not significant (x2=6.421,P=0.093).Multivariate logistic regression analysis indicated that MSM had ever tested for HIV for ≥2 times in the past 12 months (vs.MSM tested for HIV one time,aOR=1.49,95％CI:1.08-2.19) or who had ever used gay dating app (vs.MSM who not used gay dating app,aOR=2.13,95％CI:1.12-4.44) were more likely to donate blood.Conclusions Blood donation was common in MSM in China.Health education about blood donation in MSM should be strengthened to ensure the blood safety.

ABSTRACT
Objective To investigate the prevalence and risk factors of Toxoplasma gondii infection among key populations in Wuxi City,Jiangsu Province,so as to provide evidences for developing preventive and control interventions for T. gondii in-fection. Methods A questionnaire was designed to conduct face-to-face interviews to HIV/AIDS carriers/patients,tumor pa-tients,pregnant women and pet breeders. The blood samples were collected to test anti-Toxoplasma IgM and IgG antibodies by using ELISA method. Results Totally 404 participants were investigated,and 38 were positive in testing T. gondii antibodies (9.4%),and among these,37(97.4%)were IgG positive and 1(2.6%)was IgM positive. The multivariate logistic regression indicated that age,regularly contacting cats/dogs and being HIV positive were associated with the infection of T. gondii(OR=2.1,2.6 and 2.3,all P < 0.05). Breeding pets,being HIV positive and being tumor patients were more likely to infect T. gondii than being pregnant(OR = 1.5,8.1 and 2.8,all P < 0.05). Conclusion The high infection rate of T. gondii is observed among key populations in Wuxi City,so that the effective measurements should be taken to enhance the intervention among key popula-tions including immunocompromised people,pet breeders or people having bad dietary habits of eating raw food.
ABSTRACT
Objective To estimate the rates due to influenza-associated-excess-hospitalization in children aged 0-14 years in Wuxi city,Jiangsu province in 2005-2010. Methods We collected data on hospitalization due to influenza,pneumonia and other respiratory diseases from fourteen 2nd level or above hospitals in Wuxi,as well as data on influenza virological surveillance in southern China to fit the negative binomial regression models,to estimate the rate on influenza-associated-excess hospitalization. Results During 2005-2010,an average annual hospitalization rate appeared as 91.6‰(79.2‰-99.3‰). Among the total hospitalization eases,respiratory diseases accounted for 54.2%,while both influenza and pneumonia accounted for 38.1%. The average annual influenza-associated-excess-hospitalization rates due to influenza and pneumonia appeared as 1.28‰(95%CI:0.29‰-4.84‰),while 2.18‰(95%CI:0.61‰-6.79‰) due to respiratory diseases. In 2009,A(H1N1)pdm induced influenza pandemic caused 993 excess hospitalizations due to influenza/pneumonia and 1 042 excess hospitalizations due to respiratory diseases,with rates as 1.14‰ and 1.20‰ respectively. Conclusion Both seasonal and pandemic A(H1N1)pdm influenza caused considerable burden on hospitalization in children aged 0-14 years in Wuxi.
