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.

Ex Input:
Longer-term tuberculosis (TB) drug resistance surveillance among children is rare. We determined the prevalence of drug resistance among children with culture-confirmed TB from 2011 to 2013, compared these results with four previous consecutive 2-year periods and documented other mycobacterial isolates identified.', "Surveillance study of mycobacterial culture in all children aged <13 years conducted from March 2011 to February 2013 at the Tygerberg Children's Hospital, Cape Town, South Africa. Drug susceptibility testing against isoniazid (INH) and rifampicin (RMP) was performed using line-probe assay (GenoType(®) MTBDRplus). Clinical data were obtained through folder review.", 'Of 381 children, 323 (84.8%; 324 episodes) had Mycobacterium tuberculosis, 46 (12.1%) had M. bovis bacille Calmette-Guérin and 12 (3.1%) had non-tuberculous mycobacteria isolated. Forty-one (12.7%) children had M. tuberculosis resistant to INH and/or RMP; 15 (4.7%) had multidrug-resistant TB (MDR-TB). The prevalence of INH mono- or polyresistance remained stable; however, RMP monoresistance increased (0/313 in 2003-2005 vs. 6/324, 1.9%, in 2011-2013; P = 0.041); MDR-TB prevalence has declined significantly, from 26/292 (8.9%) in 2007-2009 to 15/324 (4.7%) in 2011-2013 (OR 0.50, 95%CI 0.24-0.99). The prevalence of human immunodeficiency virus co-infection has decreased significantly, from a peak of 29% to 15.3%.

Ex Output:
Does surveillance provide insight into epidemiology and spectrum of culture-confirmed mycobacterial disease in children?


Ex Input:
Hepatic myofibroblasts are relevant for pathogenesis of S. mansoni infection. In normal liver, these perisinusoidal cells are quiescent, express the lipocyte phenotype, and are located in the Disse's space, being the major site of vitamin A storage. When activated, they convert to myofibroblasts and contribute to granulomatous and diffuse liver fibrosis. In the present work, we observed that myofibroblasts obtained from granulomatous periovular inflammatory reactions in schistosome-infected mice (GR-MF) produce in vitro immunomodulatory cytokines for eosinophil activation: IL-5 and eotaxin.", 'The secretory activity of GR-MF was detected after TGF-β and IL-13 stimulation using 2D and 3D cell culture systems. In a mixed co-culture system using GR-MF with hematopoietic bone marrow cells from infected mice, we observed eosinophil survival that was dependent upon IL-5 and eotaxin, since antibodies against this cytokines decreased eosinophil population, as measured by eosinophil peroxidase activity.

Ex Output:
Are hepatic myofibroblasts derived from Schistosoma mansoni-infected mice a source of IL-5 and eotaxin : controls of eosinophil populations in vitro?


Ex Input:
The association between migraine and Parkinson's disease (PD) remains controversial. The purpose of the present population-based, propensity score-matched follow-up study was to investigate whether migraineurs are at a higher risk of developing PD.", 'A total of 41,019 subjects aged between 40 and 90 years with at least two ambulatory visits with a diagnosis of migraine in 2001 were enrolled in the migraine group. A logistic regression model that included age, sex, pre-existing comorbidities and socioeconomic status as covariates was used to compute the propensity score. The non-migraine group consisted of 41,019 propensity score-matched, randomly sampled subjects without migraine. The PD-free survival rate were estimated using the Kaplan-Meier method. Stratified Cox proportional hazard regression was used to estimate the effect of migraine on the risk of developing PD.', 'During follow-up, 148 subjects in the migraine group and 101 in the non-migraine group developed PD. Compared to the non-migraine group, the hazard ratio of PD for the migraine group was 1.64 (95% confidence interval: 1.25-2.14, p\u2009=\u20090.0004). The PD-free survival rate for the migraine group was significantly lower than that for the non-migraine group (p\u2009=\u20090.0041).
