question:
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.
answer:
no

question:
Question: Does the usage of overtube have a favorable effect on endoscopic submucosal dissection?

answer:
yes

question:
Question: Does preoperative chemotherapy for lung cancer increase surgical morbidity?
Answer: C+S did not significantly affect morbidity or mortality overall, based on clinical stage, postoperative stage, or extent of resection. The potential for enhanced survival in resectable NSCLC justifies continued study of C+S.

no
