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.

Ex Input:
Context: Next-generation sequencing (NGS) allows for sampling numerous viral variants from infected patients. This provides a novel opportunity to represent and study the mutational landscape of Hepatitis C Virus (HCV) within a single host.', 'Intra-host variants of the HCV E1/E2 region were extensively sampled from 58 chronically infected patients. After NGS error correction, the average number of reads and variants obtained from each sample were 3202 and 464, respectively. The distance between each pair of variants was calculated and networks were created for each patient, where each node is a variant and two nodes are connected by a link if the nucleotide distance between them is 1. The work focused on large components having > 5% of all reads, which in average account for 93.7% of all reads found in a patient.\Question: Does next-generation sequencing reveal large connected networks of intra-host HCV variants?

Ex Output:
Most intra-host variants are organized into distinct single-mutation components that are: well separated from each other, represent genetic distances between viral variants, robust to sampling, reproducible and likely seeded during transmission events. Facilitated by NGS, large components offer a novel evolutionary framework for genetic analysis of intra-host viral populations and understanding transmission, immune escape and drug resistance.

Ex Input:
Context: To test device integrity and objective auditory reaction for cochlear implant patients intraoperatively.', 'Our protocol for intraoperative testing of the implant device includes device electrode impedance test and neural response telemetry (NRT), which measures the electrically evoked auditory nerve compound action potentials (ECAP).', 'We completed electrode integrity tests and NRT intraoperatively on 40 patients with the Nucleus CI24M cochlear implant. We have measured normal implant function on all 40 patients and obtained ECAP results from 39 patients. Out of 33 patients with normal inner ear, typical ECAPs were recorded in 195 electrodes in all 198 testing electrodes(98.5%). In 7 patients with inner ear Mondini dysphasia, affirmative ECAP waveforms were recorded in 26 electrodes in all 42 testing electrodes. The basal electrode ECAP threshold was higher than that of the epical one.\Question: Do [ The intraoperative application of neural response telemetry with the nucleus CI24M cochlear implant ]?

Ex Output:
The intraoperative measurements of device function and NRT are quite simple, quick and with high accuracy. Inner ear malformation is an important factor that may affect NRT results.

Ex Input:
Context: Cytomegalovirus (CMV) remains the most common viral infection after pancreas-kidney transplantation (PKT). Comparative studies about CMV prophylaxis in PKT have not been developed.', 'We analyzed CMV disease in a cohort of 84 PKT recipients. All received intravenous ganciclovir during treatment with anti-thymocyte globulin and later one of the following options for pre-transplant CMV-seropositive recipients: (a) no prophylaxis (n=10 patients), (b) preemptive therapy (PT) (n=13), or (c) continuous prophylaxis (CP) for 12 weeks (n=29). Pre-transplant CMV-seronegative recipients received CP (n=21).', 'Eleven patients were excluded because of organ explantation in the first 15 days. Incidence of CMV disease in seropositive recipients was 30% under no prophylaxis, 23% under PT, and 6.9% under CP. Incidence of CMV disease under CP was 33.3% in seronegative recipients. Six of 9 episodes of CMV disease under CP occurred after finishing prophylaxis. Under CP, the incidence of CMV disease was significantly higher in seronegative than in seropositive recipients (P<0.05).\Question: Is preemptive therapy adequate for prevention of cytomegalovirus disease in pancreas-kidney transplant recipients?

Ex Output:
According to the results of our study, for CMV-seropositive PKT recipients, CP is a better strategy than PT. For CMV-seronegative recipients, 3 months of CP is an inadequate strategy.
