Input: Consider 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.

Output: no

Input: Consider Input: Question: Do xenon and nitrous oxide depress cardiac function in an isolated rat heart model?
Answer: Our data suggest that cardiac contractility was decreased by the effects of reduced O2 delivery, but both Xe and N2O did not cause further cardiac depressant effects compared to N2 in this experimental model.

Output: no

Input: Consider Input: Question: Do females have more injury road accidents on Friday the 13th?
Answer: There is no consistent evidence for females having more road traffic crashes on Fridays the 13th, based on deaths or road accident statistics. However, this does not imply a non-existent effect of superstition related anxiety on accident risk as no exposure-to-risk data are available. People who are anxious of "Black Friday" may stay home, or at least avoid driving a car.
Output: no
