Given a passage, construct a question on the basis of the information present in the passage. Construct the question in such a way that (i) it is unambiguous, (ii) it is answerable from the passage, (iii) its answer is unique (iv) it answer uses text phrases from the passage. Avoid creating questions that (i) can't be answered correctly without actually understanding the passage and (ii) uses the same words or phrases given in the passage.

Q: Anxiety and depression frequently co-occur in the elderly and in patients with dementia. Prior research has shown that depression is related to the risk of dementia, but the effect of anxiety on dementia remains unclear. We studied whether anxiety symptoms and anxiety disorders are associated with the risk of dementia and cognition.', 'We studied 2,708 nondemented participants from the prospective, population-based Rotterdam Study who underwent the Hospital Anxiety and Depression Scale (HADS) (sample I, baseline 1993-1995) and 3,069 nondemented participants who underwent screening for anxiety disorders (sample II, baseline 2002-2004). In 1993-1995, anxiety symptoms were assessed using the HADS. In 2002-2004, anxiety disorders were assessed using the Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition. In both study samples, participants were continuously monitored for dementia until January 1, 2011. Cognition was tested in 2002-2004 and at a follow-up visit in 2009-2011 in sample II only.', 'In sample I, 358 persons developed dementia, and in sample II, 248 persons developed dementia. We did not find an association with the risk of dementia for anxiety symptoms (hazard ratio 1.05, 95% confidence interval: 0.77-1.43, Wald statistic 0.08, p= 0.77, df= 1) or for anxiety disorders (hazard ratio 0.92, 95% confidence interval: 0.58-1.45, Wald statistic 0.14, p= 0.71, df= 1). We could demonstrate an association of anxiety disorders with poor cognition cross-sectionally, but this attenuated after additional adjustments.

A: Is anxiety associated with the risk of dementia or cognitive decline : the Rotterdam Study?

Q: Coinfection with hepatitis C virus (HCV) is present in one-third of all human immunodeficiency virus (HIV)-infected individuals in the United States and is associated with rapid progression of liver fibrosis and poor response to pegylated interferon (IFN) and ribavirin. In this study we examined gene expression profiles in peripheral blood mononuclear cells (PBMCs) from different groups of individuals who are monoinfected or coinfected with HIV and HCV. Data showed that HIV and HCV viremia up-regulate genes associated with immune activation and immunoregulatory pathways. HCV viremia is also associated with abnormalities in all peripheral immune cells, suggesting a global effect of HCV on the immune system. Interferon-alpha-induced genes were expressed at a higher level in PBMCs from HIV-infected individuals. HCV and HIV infections leave distinct profiles or gene expression of immune activation in PBMCs. HIV viremia induces an immune activated state; by comparison, HCV infection induces immunoregulatory and proinflammatory pathways that may contribute to progression of liver fibrosis.

A: Do human immunodeficiency virus and hepatitis C infections induce distinct immunologic imprints in peripheral mononuclear cells?

Q: Studies using self-report rating scales suggest a considerable overlap regarding symptom complaints in patients with fibromyalgia (FM) and functional dyspepsia (FD), while clinical assessments point to important psychological differences.', 'To test the hypothesis that measurement of psychological state by means of content analysis of speech will demonstrate differentiation between the two patient groups and between patients with these disorders and age-matched population-based random sample controls.', 'The Giessener Symptom Complaints Checklist assessed somatic complaints. The computerised Gottschalk-Gleser content analysis method assessed psychological state in 42 females with FM, 17 females with FD and 48 population-based, randomly selected control subjects.', 'FM patients score higher on mutilation anxiety than FD and control subjects. FD patients had the highest score for death anxiety. Mutilation anxiety and low hope score identified FM patients (sensitivity 68%, specificity 81%, overall classification 75%), but only 19% of the variation in total somatic complaints could be predicted from these or other psychological state scores. In FD patients, however, death anxiety explained 59% of the variance in gastrointestinal complaints.

A:
Does mutilation anxiety differ among females with fibromyalgia and functional dyspepsia and population controls?
