This paper describes a paper and pencil questionnaire that measures heart disease risk knowledge in people with diabetes. The Heart Disease Fact Questionnaire (HDFQ) is a 25-item questionnaire that was developed to tap into respondents' knowledge of major risk factors for the development of CHD. Approximately half of these items specifically address diabetes-related CHD risk factors. Based on extensive pilot data, the current study analyzed responses from 524 people with diabetes to assess the psychometric properties. The HDFQ is readable to an average 13-year old and imposes little burden. It shows good content and face validity. It demonstrates adequate internal consistency, with Kuder-Richardson-20 formula = 0.77 and good item-total correlations. Item analysis showed a desirable range in P-values. In discriminant function analyses, HDFQ scores differentiated respondents by knowledge of their own cardiovascular health, use of lipid lowering medications, health insurance status, and educational attainment, thus indicating good criterion related validity. This measure of heart disease risk knowledge is brief, understandable to respondents, and easy to administer and score. Its potential for use in research and practice is discussed. Future research should establish norms as well as investigate its test-retest reliability and predictive validity.

Ex Output:
Development of a questionnaire to measure heart disease risk knowledge in people with diabetes: the Heart Disease Fact Questionnaire.

In order to investigate the prevalence of infections with three feline retroviruses feline immunodeficiency virus (FIV), feline leukemia virus (FeLV) and feline syncytial virus (FSV) in Taiwan, we collected a total of 75 blood samples from cats from veterinary hospitals, a breeding cattery and a homeless shelter in 1993 and 1994. We examined the presences of anti-FIV and FSV antibodies and FeLV-p27 antigen in these samples by the indirect immunofluorescence and/or enzyme-linked immunosorbent assays. All of the serum samples positive for FIV were obtained from homeless cats and the overall FIV positive rate was 4%. The overall positive rates of FSV and FeLV were 28% and 1.3%, respectively. From these results, together with previous seroepidemiological surveys by others, it was revealed that the prevalence of FIV and FeLV infections appeared to be lower in Taiwan than in the United States or Japan. In contrast, the prevalence of FSV infection in Taiwan was as high as that in Japan.

Ex Output:
Seroepidemiological survey of feline retrovirus infections in cats in Taiwan in 1993 and 1994.

Although bloodbrain barrier (BBB) compromise is central to the etiology of diverse central nervous system (CNS) disorders, endothelial receptor proteins that control BBB function are poorly defined. The endothelial G-protein-coupled receptor (GPCR) Gpr124 has been reported to be required for normal forebrain angiogenesis and BBB function in mouse embryos, but the role of this receptor in adult animals is unknown. Here Gpr124 conditional knockout (CKO) in the endothelia of adult mice did not affect homeostatic BBB integrity, but resulted in BBB disruption and microvascular hemorrhage in mouse models of both ischemic stroke and glioblastoma, accompanied by reduced cerebrovascular canonical Wnt-catenin signaling. Constitutive activation of Wnt-catenin signaling fully corrected the BBB disruption and hemorrhage defects of Gpr124-CKO mice, with rescue of the endothelial gene tight junction, pericyte coverage and extracellular-matrix deficits. We thus identify Gpr124 as an endothelial GPCR specifically required for endothelial Wnt signaling and BBB integrity under pathological conditions in adult mice. This finding implicates Gpr124 as a potential therapeutic target for human CNS disorders characterized by BBB disruption.

Ex Output:
Gpr124 is essential for bloodbrain barrier integrity in central nervous system disease
