[Q]: 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.
[A]: no


[Q]: Question: Are gSTT1 and GSTM1 gene deletions associated with hepatotoxicity caused by antitubercular drugs?
Answer: Hundred and fifty-one subjects (51 cases, 100 controls) were enrolled. Odds ratio for GSTM1 null genotype was 1.00 (95% CI 0.51-1.97) and GSTT1 null was 2.02 (95% CI 0.39-10.39), respectively, showing that these genotypes are not associated with hepatotoxicity.
[A]:
no
