In this task, you are given a passage which has a question and the context. You have to generate an answer to the question based on the information present in the context.

Ex Input:
Context: In adults with growth hormone (GH) deficiency (GHD), GH treatment restores impaired endothelial function, a precursor of cardiovascular disease. Its effect in children with GHD is unknown.', 'Three months of GH (0.3 mg/kg/wk) were given to nine children with GHD. Endothelial function was measured via reactive hyperemic response. Forearm blood flow (FBF, strain gauge plethysmography) was measured before and after 5 min of upper arm arterial occlusion. Blood pressure and lipid, insulin and glucose levels were measured. Pretreatment endothelial function was compared to 18 previously studied control children.', 'Percent fall in forearm vascular resistance was greater in controls (81.2 +/- 1.9%) than in children with GHD (69.6 +/- 5.3%, p = 0.021) but was not affected by GH (60.6 +/- 7.5%). GH markedly increased HOMAIR (21 +/- 7 versus 43 +/- 8, p = 0.004). Plasma lipid levels did not significantly differ.\Question: Does growth hormone ( GH ) treatment restore endothelial function in children with GH deficiency?

Ex Output:
These results indicate that endothelial function is impaired in children with GHD. GH therapy does not restore the impairment.

Context: We aimed to study the association between cytomegalovirus (CMV) infection and hypertension in Kazakh and Han populations from Xinjiang Province, China.', 'We analyzed data on 800 Kazakhs (467 hypertension patients and 333 healthy control participants) and 800 Hans (482 hypertension patients and 318 healthy control participants) aged 18-84 years old. ELISA and real-time quantitative PCR coupled with restriction fragment length polymorphism analysis were applied for determining CMV infection and glycoprotein B (gB) genotypes, respectively.', 'Serologic evidence of CMV infection was obtained for 95.4% and 90.1% of the Kazakhs and Hans, respectively. The CMV seroprevalence rates among the Kazakh and Han participants with hypertension were 96.8% and 89.8%, respectively. Multiple logistic regression analyses revealed statistically significant independent associations between CMV seropositivity and hypertension in Kazakh males and between CMV antibody titers and hypertension in Hans; significant relationships also existed between CMV antibody titers and blood pressure in Hans. In Kazakhs, 3 CMV gB genotypes were identified: gB2 and genotype mixtures gB1+gB2 and gB2+gB3. In Hans, 4 CMV gB genotypes were identified: gB1, gB2, gB1+gB2, and gB2+gB3. Of the 4 studied genotypes, gB2+gB3 showed a significant independent association with hypertension in Kazakh females.\Question: Is human cytomegalovirus infection associated with essential hypertension in Kazakh and Han Chinese populations?

Ex Output:
CMV infection is associated with essential hypertension in Kazakh males and Hans in Xinjiang. CMV seropositivity is associated with hypertension in Kazakh males, and CMV antibody titers are associated with blood pressure and hypertension in Han males and females. Moreover, the CMV gB2+gB3 genotype mixture is associated independently with essential hypertension in Kazakh females.

Context: Although Alzheimer's disease (AD) is associated with early death, its life expectancy differs greatly between patients. A better understanding of this heterogeneity may reveal important disease mechanisms underlying the malignancy of AD. The aim of this study was to examine the relation between AD pathologies and early death in AD caused by dementia.", 'At a memory clinic, 247 referred consecutive patients with AD were monitored during 12.61.6 years. Multivariate Cox regression analyses were performed with baseline measures of amyloid beta (A) pathology (APOE genotype, cerebrospinal fluid (CSF) A42) tau pathology (CSF phosphorylated tau and total tau), cerebrovascular pathology (white-matter lesions and CSF/serum albumin ratio), neuroinflammatory pathology (CSF soluble vascular cell adhesion molecule-1, sVCAM-1), frontal, temporal, and central brain atrophies, global cognition, sex, and age. Comorbidities and medications also were analyzed. All continuous variables were transformed to z scores to compare hazard ratios (HRs) and 95% confidence intervals (CIs).', 'At follow-up, 89% of the patients had died. The mean survival time was 6.43.0 years. The AD pathology that independently predicted an early death caused by dementia was cerebral inflammation (sVCAM-1; HR, 1.32; 95% CI, 1.07-1.64). Other independent predictors were lower global cognition (HR, 0.51; 95% CI, 0.43-0.61), frontal atrophy (HR, 1.38; 95% CI, 1.12-1.70), and medial temporal atrophy (HR, 1.23; 95% CI, 1.02-1.49). When examining death caused by dementia and related causes (vascular diseases and infections), age (HR, 1.23; 95% CI, 1.04-1.46) and cerebrovascular pathology (white-matter lesions: HR, 1.17; 95% CI, 1.01-1.36; and CSF/serum albumin ratio: HR, 1.16; 95% CI, 1.001-1.34) were also significant risk factors in addition to the previous variables. No comorbidity or medication was significant in the specific-cause models.\Question: Is cerebral inflammation an underlying mechanism of early death in Alzheimer 's disease : a 13-year cause-specific multivariate mortality study?

Ex Output:
This is the first study to link neuroinflammation independently to early death in AD and, hence, a rapidly progressing disease. Frontal and medial temporal atrophies and low cognition were also significant predictors. These are probably downstream biomarkers that reflect neuronal degeneration and late-stage disease. Our results suggest that inflammation, and not amyloid or tau pathology, is an independent underlying mechanism in the malignancy of AD.
