Background
Adult onset autoimmune enteropathy (AIE) is a rare condition characterized by diarrhea refractory to dietary therapy diagnosed in patients with evidence of autoimmune conditions. Auto-antibodies to gut epithelial cells and other tissues are commonly demonstrated. Despite increasing awareness, the pathogenesis, histologic, immunologic and clinical features of AIE remain uncertain. There remains controversy regarding the diagnostic criteria, the frequency and types of auto-antibodies and associated autoimmune conditions, and the extent and types of histologic and immunologic abnormalities. CD4+ T-cells are thought to at least responsible for this condition; whether other cell types, including B- and other T-cell subsets are involved, …
A Brief Overview Of Adolescent Developmental Problems In Hong Kong, Daniel T. L. Shek, Hing Keung Ma, Rachel C. F. Sun
A Brief Overview Of Adolescent Developmental Problems In Hong Kong, Daniel T. L. Shek, Hing Keung Ma, Rachel C. F. Sun
Pediatrics Faculty Publications
Several adolescent developmental problems in Hong Kong are briefly reviewed in this paper. First, rising adolescent substance abuse trends are described. Second, Internet use problems and Internet addiction among young people are examined. Third, worrying trends in adolescent sexuality are identified. Fourth, phenomena on bullying among young people are reviewed. Finally, phenomena related to adolescent materialistic orientation are focused upon. With reference to these adolescent developmental problems, possible solutions are briefly discussed particularly with reference to the ecological perspective. It is argued that the related scientific literature provides useful pointers for designing the curriculum in the extension phase of the …
Pre- And Post-Bronchodilator Lung Function As Predictors Of Mortality In The Lung Health Study, David M. Mannino, Enrique Diaz-Guzman, Sonia Buist
Pre- And Post-Bronchodilator Lung Function As Predictors Of Mortality In The Lung Health Study, David M. Mannino, Enrique Diaz-Guzman, Sonia Buist

BACKGROUND: Chronic obstructive pulmonary disease (COPD) is supposed to be classified on the basis of post-bronchodilator lung function. Most longitudinal studies of COPD, though, do not have post-bronchodilator lung function available. We used pre-and post bronchodilator lung function data from the Lung Health Study to determine whether these measures differ in their ability to predict mortality.
METHODS: We limited our analysis to subjects who were of black or white race, on whom we had complete data, and who participated at either the 1 year or the 5 year follow-up visit. We classified subjects based on their baseline lung function, according …
No Evidence Of Association Between Hiv-1 And Malaria In Populations With Low Hiv-1 Prevalence, Diego F. Cuadros, Adam J. Branscum, Gisela García-Ramos
No Evidence Of Association Between Hiv-1 And Malaria In Populations With Low Hiv-1 Prevalence, Diego F. Cuadros, Adam J. Branscum, Gisela García-Ramos
Biology Faculty Publications
BACKGROUND: The geographic overlap between HIV-1 and malaria has generated much interest in their potential interactions. A variety of studies have evidenced a complex HIV-malaria interaction within individuals and populations that may have dramatic effects, but the causes and implications of this co-infection at the population level are still unclear. In a previous publication, we showed that the prevalence of malaria caused by the parasite Plasmodium falciparum is associated with HIV infection in eastern sub-Saharan Africa. To complement our knowledge of the HIV-malaria co-infection, the objective of this work was to assess the relationship between malaria and HIV prevalence in …
Response To An Abnormal Ovarian Cancer-Screening Test Result: Test Of The Social Cognitive Processing And Cognitive Social Health Information Processing Models, Michael A. Andrykowski, Edward J. Pavlik
Response To An Abnormal Ovarian Cancer-Screening Test Result: Test Of The Social Cognitive Processing And Cognitive Social Health Information Processing Models, Michael A. Andrykowski, Edward J. Pavlik
Behavioral Science Faculty Publications
All cancer screening tests produce a proportion of abnormal results requiring follow up. Consequently, the cancer-screening setting is a natural laboratory for examining psychological and behavioural response to a threatening health-related event. This study tested hypotheses derived from the social cognitive processing and cognitive-social health information processing models in trying to understand response to an abnormal ovarian cancer (OC) screening test result. Women (n = 278) receiving an abnormal screening test result a mean of 7 weeks earlier were assessed prior to a repeat screening test intended to clarify their previous abnormal result. Measures of disposition (optimism, informational coping style), …

The human ability to flexibly alternate between tasks represents a central component of cognitive control. Neuroimaging studies have linked task switching with a diverse set of prefrontal cortex (PFC) regions, but the contributions of these regions to various forms of cognitive flexibility remain largely unknown. Here, subjects underwent functional brain imaging while they completed a paradigm that selectively induced stimulus, response, or cognitive set switches in the context of a single task decision performed on a common set of stimuli. Behavioral results indicated comparable reaction time costs associated with each switch type. Domain-general task-switching activation was observed in the inferior …
