[Effectiveness of integrated schistosomiasis control strategy in marshlands of Qixia District, Nanjing City].

Objective: To evaluate the effectiveness of integrated schistosomiasis control strategy in marshlands of Qixia District from 2004 to 2013.

Methods: The endemic situation and integrated control data of schistosomiasis in Qixia District from 2004 to 2013 were collected, and the morbidity and Oncomelania hupensis snail status before and after the implementa- tion of integrated schistosomiasis control strategy were compared.

Results: Following 10-year integrated schistosomiasis control, the human schistosome infection rate gradually decreased in Qixia District, and no infection was detected since 2007.

[Surveillance of schistosomiasis in a national surveillance site, Nanzhong Village, Nanjing City, 2010-2011].

Objective: To understand the dynamic of schistosomiasis epidemic situation in a national surveillance site, Nanzhong Village, Qixia District, Nanjing City, 2010-2011, so as to provide the evidence for evaluating the control effect and formulating prevention countermeasures.

Methods: According to the National Schistosomiasis Monitoring Program, the Oncomelania snail status and the situation of endemic schistosomiasis were surveyed and the data were analyzed statistically.

Results: The emergence rate of frames with living Oncomelania snails decreased by 11.

[Snail control effect of film covering method in fish ponds and ditches].

Objective: To evaluate the snail control effect of a film covering method in fish ponds and ditches.

Methods: Two fish ponds and 2 ditches with Oncomelania snails were selected as pilots, and 1 fish pond as Group A1 and I ditch as Group B1 received niclosamide spraying + film covering, and another fish pond as Group A2 and another ditch as Group B2 received niclosamide spraying only. The snail control effects were observed at 15, 30, 90 d and 360 d after the test, and the fish and other aquatic were also observed.

The relationship of cardiovascular risk factors to Alzheimer disease in Choctaw Indians.

Objectives: To test the hypothesis that cardiovascular risk factors (CRFs) influence predisposition to and the clinical course of Alzheimer disease (AD), the authors compared Choctaw Indians, a group with known high CRF with white persons with AD. In addition to CRF history, the authors investigated the frequency of apolipoprotein E4 (apoE4) genotype andplasma homocysteine (HC) levels.

Method: The authors compared 39 Choctaw Indians with AD and 39 Choctaw Indians without AD to 39 white persons with AD with all groups similar in age.

Brain MRI, apoliprotein E genotype, and plasma homocysteine in American Indian Alzheimer disease patients and Indian controls.

We obtained brain MRIs, plasma homocysteine levels and apolipoprotein E genotyping for 11 American Indian Alzheimer disease (AD) subjects and 10 Indian controls. We calculated white matter hyperintensity volume (WMHV), whole brain volume (WBV), and ratio of white matter hyperintensity volume to whole brain volume (WMHV/WBV). There were no significant differences between AD subjects and controls in gender, history of hypertension, diabetes, or history of high cholesterol, but hypertension and diabetes were more common among AD subjects.
