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.

The clinical significance of the hepatitis B virus core-related antigen (HBcrAg) assay in monitoring the antiviral effects of lamivudine is reviewed.', 'The HBcrAg assay simultaneously measured serum levels of hepatitis B core (HBc) and e (HBe) antigens using monoclonal antibodies which recognize common epitopes of these two denatured antigens.', 'Although serum HBcrAg levels correlated linearly with those of hepatitis B virus (HBV) DNA in natural course, the decrease in HBcrAg was significantly slower than in HBV DNA after initiation of lamivudine administration. We analyzed the clinical significance of HBV DNA and HBcrAg levels to predict the occurrence of lamivudine resistance. HBV DNA measurement may be useful to identify patients who are at high risk of developing lamivudine resistance, and HBcrAg measurement may help to detect patients who are at low risk of drug resistance. The measurement of HBcrAg was also found to be a useful prognosticator for reactivation of hepatitis after cessation of lamivudine administration.
Is hepatitis B core-related antigen assay useful for monitoring the antiviral effects of nucleoside analogue therapy?

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\xa0= 0.77, df\xa0= 1) or for anxiety disorders (hazard ratio 0.92, 95% confidence interval: 0.58-1.45, Wald statistic 0.14, p\xa0= 0.71, df\xa0= 1). We could demonstrate an association of anxiety disorders with poor cognition cross-sectionally, but this attenuated after additional adjustments.
Is anxiety associated with the risk of dementia or cognitive decline : the Rotterdam Study?

Trauma centers often receive transfers from lower-level trauma centers or nontrauma hospitals. The aim of this study was to analyze the incidence and pattern of secondary overtriage to our Level I trauma center.', 'We performed a 2-year retrospective analysis of all trauma patients transferred to our Level I trauma center and discharged within 24 hours of admission. Reason for referral, referring specialty, mode of transport, and intervention details were collected. Outcomes measures were incidence of secondary overtriage as well as requirement of major or minor procedure. Major procedure was defined as surgical intervention in the operating room. Minor procedures were defined as procedures performed in the emergency department.', 'A total of 1,846 patients were transferred to our Level I trauma center, of whom 440 (24%) were discharged within 24 hours of admission. The mean (SD) age was 35 (21) years, 72% were male, and mean (SD) Injury Severity Score (ISS) 4 (4). The most common reasons for referral were extremity fractures (31%), followed by head injury (23%) and soft tissue injuries (13%).Of the 440 patients discharged within 24 hours, 380 (86%) required only observation (268 of 380) or minor procedure (112 of 380). Minor procedures were entirely consisted of fracture management (n = 47, 42%) and wound care (n = 65, 58%). The mean (SD) interfacility transfer distance was 45 (46) miles. Mean (SD) hospital charges per transfer were $12,549 ($5,863).
