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.

Q: Context: Bortezomib-induced peripheral neuropathy (BIPN) is a significant neurotoxicity, requiring dose reduction or the delay of treatment. In a multicentre trial including 97 % Caucasians and 3 % Asians, BIPN was shown to occur less frequently in cases in which bortezomib was administered subcutaneously. Considering the different pharmacokinetics between Caucasians and Asians, we analysed BIPN according to the administration route, specifically in Korean myeloma patients.', 'We surveyed the prescribed anticonvulsants for the treatment of BIPN and analysed the data after stratifying the results by the cumulative dose of bortezomib. Exclusion criteria were as follows: treated with <2 doses of bortezomib, change in the administration route during the treatment, or receiving anticonvulsants for other reasons prior to bortezomib administration.', 'A total of 101 patients were enrolled; 60 were treated with bortezomib and dexamethasone, and 37 were treated with bortezomib, melphalan, and prednisolone. The median number of treatment courses was four for each regimens. The median exposure to bortezomib for all patients was 19 mg/m(2). Progression-free survival (PFS) and overall survival rates were not statistically different between the groups. There was no difference in the proportion of patients requiring medical treatment (p = 0.388). After stratifying the results, BIPN developed less frequently when bortezomib was administered subcutaneously rather than intravenously in patients receiving more than 23.4 mg/m(2) of bortezomib (p < 0.05).\Question: Is bortezomib-associated peripheral neuropathy requiring medical treatment decreased by administering the medication by subcutaneous injection in Korean multiple myeloma patients?

A: Since the responses were potent regardless of administration route, the subcutaneous injection of bortezomib should be considered in Asian myeloma patients who are expected to achieve a longer PFS with bortezomib.

Q: 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?

A: 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.

Q: Context: To evaluate whether genotypes of interleukin (IL)-6 gene promoter positions -174 and -572 are associated with histologic chorioamnionitis and neonatal inflammatory disease in preterm infants.', 'DNA from very low birth weight or very preterm infants (n = 107) was genotyped for IL-6-174 and -572 polymorphisms (GG/GC/CC). The placentas were analyzed for histological inflammatory findings. Data on neonatal inflammatory diseases, including chronic lung disease (CLD), necrotizing enterocolitis (NEC), and septicemia, were collected using the definitions of the Vermont Oxford Network database.', 'In univariate analyses, the IL-6-174 GG genotype was associated with a higher incidence of histologic chorioamnionitis. In multivariate analyses, the -174 GG and -572 GC genotypes were correlated with histologic chorioamnionitis (P = .039 and .009, respectively). Gestational age was not associated with genotype polymorphisms. IL-6-174 genotypes were not associated with CLD and/or NEC, but the CC genotype was correlated with septicemia in both univariate and multivariate analyses (P = .027). IL-6-572 genotypes were not associated with neonatal inflammatory disease.\Question: Is interleukin-6 polymorphism associated with chorioamnionitis and neonatal infections in preterm infants?

A:
The IL-6-174 GG and -572 GC genotypes were associated with a higher incidence of histologic chorioamnionitis, and the IL-6-174 CC genotype was associated with septicemia in preterm infants. These findings suggest that the genetic composition of the IL-6 promoter area plays a significant role in the pathogenesis of chorioamnionitis and neonatal infections.
