Non-traditional biomarkers in the prediction of cardiovascular events among Chinese
Poster PresentationINTRODUCTION: Biomarkers of subclinical systemic chronic inflammation are increasingly recognised as a key player in atherosclerosis. C-reactive protein, measured using high-sensitivity assay (hsCRP), is the most promising inflammatory marker in predicting the risk of cardiovascular diseases (CVD). As obesity is associated with disregulated expression of various adipokines, either pro-inflammatory or anti-inflammatory, such adipokines may also serve as non-traditional biomarkers for the accelerated atherosclerosis associated with obesity. In this prospective cohort study, we examined the predictive value of a variety of non-traditional biomarkers for CVD among Hong Kong Chinese, and determined if they would …published_or_final_versionThe 17th Medical Research Conference, The University of Hong Kong, Hong Kong, 14 January 2012.

Plasma lipocalin-2 concentration is related to blood pressure and is increased in hypertension
Oral PresentationINTRODUCTION: Lipocalin-2 is secreted by adipocytes and is upregulated in obesity. As obesity is known to be a cause of hypertension, we investigated whether the plasma level of lipocalin-2 is related to blood pressure and hypertension. METHODS: The plasma concentration of lipocalin-2 was measured by immunoassay in 1925 subjects of …published_or_final_versionThe 17th Medical Research Conference, The University of Hong Kong, Hong Kong, 14 January 2012.

Plasma fibrinogen level as a predictor of incident metabolic syndrome in a community-based prospective study in Hong Kong Chinese
BACKGROUND AND AIMS: Metabolic syndrome (MS) comprises a constellation of metabolic abnormalities associated with a high risk of developing diabetes and cardiovascular diseases. Central obesity, with related insulin resistance and inflammation are considered the core of the underlying pathogenesis of MS. Fibrinogen, an acute-phase reactant in the coagulation cascade, has been shown to play pivotal role in determining the extent of local or systemic inflammation. In this study, we examined whether plasma fibrinogen was predictive of incident MS in a community-based Chinese cohort. MATERIALS AND METHODS: Subjects were recruited from the Hong Kong Cardiovascular Risk Factors Prevalence Study (CRISPS) cohort. 2780 subjects were recruited in 1995-6 with baseline assessment performed. 1416 subjects without MS at …postprin
Implication of the type 2 diabetes susceptibility loci identified in genome-wide association studies: long-term follow-up studies in Southern Chinese
Poster PresentationOBJECTIVE: Genome-wide association (GWA) studies have led to the identification of novel susceptibility loci which showed promising associations with type 2 diabetes (T2DM). This project aimed to establish the role of these novel T2DM-susceptibility loci in Southern Chinese. METHODS: Seventeen T2DM-associated single nucleotide polymorphisms (SNPs) were examined …published_or_final_versionThe 17th Medical Research Conference, The University of Hong Kong, Hong Kong, 14 January 2012.

Genetics of Apparently Sporadic Pheochromocytoma and Paraganglioma in a Chinese Population
© Georg Thieme Verlag KG Stuttgart New York.Identification of germline mutation in patients with apparently sporadic pheochromocytomas and paragangliomas is crucial. Clinical indicators, which include young age, bilateral or multifocal, extra-adrenal, malignant, or recurrent tumors, predict the likelihood of harboring germline mutation in Caucasian subjects. However, data on the prevalence of germline mutation, as well as the applicability of these clinical indicators in Chinese, are lacking. We conducted a cross-sectional study at a single endocrine tertiary referral center in Hong Kong. Subjects with pheochromocytomas and paragangliomas were evaluated for the presence of germline mutations involving 10 susceptibility genes, which included NF1, RET, VHL, SDHA, SDHB, SDHC, SDHD, TMEM 127, MAX, and FH genes. Clinical indicators were assessed for their association with the presence of germline mutations. Germline mutations, 2 being novel, were found in 24.4% of the 41 Chinese subjects recruited and 11.4% among those with apparently sporadic presentation. The increasing number of the afore-mentioned clinical indicators significantly correlated with the likelihood of harboring germline mutation in one of the 10 susceptibility genes. (r=0.757, p=0.026). The presence of 2 or more clinical indicators should prompt genetic testing for germline mutations in Chinese subjects. In conclusion, our study confirmed that a significant proportion of Chinese subjects with apparently sporadic pheochromocytoma and paraganglioma harbored germline mutations and these clinical indicators identified from Caucasians series were also applicable in Chinese subjects. This information will be of clinical relevance in the design of appropriate genetic screening strategies in Chinese populations.postprin

Prevalência e fatores associados de infecção pelo M. tuberculosis entre Agentes Comunitários de Saúde.
Introdução: A tuberculose é uma doença milenar e que, ainda hoje, constitui grave problema de saúde pública em todo o mundo. Objetivo: Estimar a prevalência e os fatores associados à infecção latente pelo MTB entre Agentes Comunitários de Saúde atuantes na rede básica de saúde de Municípios prioritários para o controle de TB Cuiabá/MT, Manaus/AM, Salvador/BA e Vitória/ES. Métodos: Estudo de corte transversal no qual os dados foram coletados através de questionário, composto de questões abertas e fechadas sobre características pessoais; informações a respeito da tuberculose; utilização de medidas preventivas, etc. Aplicou-se prova tuberculínica, com leitura após 48-72h por enfermeiros treinados, considerando como ponte de corte positivo 5 e 10 mm de enduração. A análise múltipla foi feita por meio de regressão logística hierarquica. Foram incluídas no modelo as variáveis que mostraram associação com desfecho com p<0,1. Permaneceram no modelo as variáveis independentes que mantiveram associação com desfecho após ajuste (p<0,05). Este estudo obteve aprovação do Comitê de Ética em Pesquisa com seres humanos do Centro de Ciências da Saúde da Universidade Federal do Espírito Santo, n° de registro CEP-07/2010 e das Secretarias Municipais de Saúde, por meio de uma Carta de Apresentação. Resultados: 322 Agentes Comunitários de Saúde (ACS) aceitaram participar voluntariamente do estudo por meio da assinatura do Termo de Consentimento Livre e Esclarecido. Destes, 10 não compareceram para leitura, sendo estes considerados como perdas, além do que um indivíduo foi excluído pelo fato do teste rápido para HIV ter resultado positivo, perfazendo uma amostra final de 311 participantes. Ainda em relação aos ACS triados, a positividade a Prova Tuberculínica, levando-se em consideração o ponto de corte ao teste de 10 mm e de 5 mm de enduração, foi de 37,30% (IC95%: 0,31-0,42) e de 57,88% (IC95%: 0,52-0,63), respectivamente.Conclusões: Faz-se necessário um programa de realização de Prova Tuberculínica, de rotina, combinado com intervenções para reduzir o risco de transmissão nosocomial, bem como a realização de outros estudos para avaliar a eficácia de novos testes para detecção de tuberculose latente
