In this task, you are given a passage which has a question and the context. You have to generate an answer to the question based on the information present in the context.

Context: A malaria management protocol was developed and implemented at a tertiary care children's hospital in September 1999. We retrospectively evaluated children admitted with malaria 10-years preimplementation and 7-years postimplementation to determine the impact the protocol had on management and time delay to appropriate antimalarial therapy.", 'This before and after study compared all admissions with the discharge diagnosis of malaria in the study period. Retrospective chart review was used to determine the time from emergency department (ED) registration to administration of antimalarial treatment. Other outcomes measured included mortality, length of hospital stay, and intensive care unit admission.', 'Fifty-eight admissions were identified during the defined period, most of which were due to Plasmodium falciparum[r] malaria. Thirty-one (53.4%) cases were before implementation of the protocol. Children were more likely to receive appropriate investigations to assess for possible severe malaria before transfer from the ED to the ward after protocol implementation (18% vs. 63%, P = 0.005). Analysis of index cases of malaria, excluding patients diagnosed after the diagnosis of a sibling, showed there was a significant reduction in time to medication administration (8 vs. 5.5 hours, P = 0.036).\Question: Does protocol for management of imported pediatric malaria decrease time to medication administration?
After broad-based implementation of a malaria treatment protocol in a pediatric hospital, children received more thorough investigations, were more likely to receive therapy before leaving the ED and had a shorter delay before receiving appropriate antimalarial therapy.

Context: To determine the extent of genetic variation among internationally collected HIV-1 isolates, to analyse phylogenetic relationships and the geographic distribution of different variants.', 'Phylogenetic comparison of 70 HIV-1 isolates collected in 15 countries on four continents.', 'To sequence the complete gag genome of HIV-1 isolates, build multiple sequence alignments and construct phylogenetic trees using distance matrix methods and maximum parsimony algorithms.', 'Phylogenetic tree analysis identified seven distinct genotypes. The seven genotypes were evident by both distance matrix methods and maximum parsimony analysis, and were strongly supported by bootstrap resampling of the data. The intra-genotypic gag distances averaged 7%, whereas the inter-genotypic distances averaged 14%. The geographic distribution of variants was complex. Some genotypes have apparently migrated to several continents and many areas harbor a mixture of genotypes. Related variants may cluster in certain areas, particularly isolates from a single city collected over a short time.\Question: Does phylogenetic analysis of gag genes from 70 international HIV-1 isolates provide evidence for multiple genotypes?
The genetic variation among HIV-1 isolates is more extensive than previously appreciated. At least seven distinct HIV-1 genotypes can be identified. Diversification, migration and establishment of local, temporal 'blooms' of particular variants may all occur concomitantly.

Context: Complement Factor I (CFI) and the CD46 complement regulator (CD46) play an important role in the complement activation pathways, which is known to affect the development of uveitis. The present study was performed to investigate the association of the CFI and CD46 genes with acute anterior uveitis (AAU).', 'A total of 600 subjects (300 patients with AAU and 300 healthy controls) were recruited for this case-control study. Six CFI single nucleotide polymorphisms (SNP) (rs7356506, rs10029485, rs11726949, rs12512308, rs7438961, rs998538) and four CD46 SNPs (rs12138764, rs2466571, rs2796278, rs7545126) were genotyped using Sequenom MassARRAY technology. Allele and genotype frequencies were compared between patients and controls using the χ(2) test. Analyses were stratified for gender, human leukocyte antigen (HLA)-B27, and ankylosing spondylitis status.', 'Rs7356506 in the CFI gene was found to be protective against AAU. There was a significant increase in the frequency of the A allele (p=0.003, pc=0.03, OR=0.684, CI 0.534 to 0.876) and AA homozygosity (p=0.004, pc=0.04, OR=0.624, CI 0.452 to 0.862) in AAU patients as compared to controls. Stratified analysis, according to gender and HLA-B27 status for AAU, also revealed the association with CFI-rs7356506. None of the tested SNPs of CD46 were associated with AAU.\Question: Is cFI-rs7356506 a genetic protective factor for acute anterior uveitis in Chinese patients?

This study has revealed a significant association between AAU and CFI-rs7356506, suggesting that CFI is involved in the pathogenesis of AAU, and that its influence on AAU may differ depending on gender and HLA-B27 status.
