Ex Input:
Question: Is 14-3-3η a novel mediator associated with the pathogenesis of rheumatoid arthritis and joint damage?

Ex Output:
yes


Ex Input:
Question: Does antenatal receipt of sulfadoxine-pyrimethamine exacerbate pregnancy-associated malaria despite the expansion of drug-resistant Plasmodium falciparum : clinical outcomes from the QuEERPAM study?
Answer: In this longitudinal study of malaria at delivery, the receipt of SP as IPTp did not potentiate PAM morbidity despite the increasing prevalence and fixation of SP-resistant P. falciparum haplotypes. Even when there is substantial resistance, SP may be used in modified IPTp regimens as a component of comprehensive antenatal care.

Ex Output:
no


Ex Input:
Question: Does in Heart Failure Patients with Left Bundle Branch Block Single Lead MultiSpot Left Ventricular Pacing Improve Acute Hemodynamic Response To Conventional Biventricular Pacing . A Multicenter Prospective , Interventional , Non-Randomized Study?
Answer: In patients with LBBB MultiSPOT LV pacing demonstrated comparable improvement in contractility to best conventional BiV pacing. Optimization of atrioventricular delay is important for the best performance for both BiV and MultiSPOT pacing configurations.

Ex Output:

no
