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: Although successful cochlear implantation of patients with deafness following meningitis is expected, long-term stability of electrical current requirements has not been systematically evaluated. This study evaluated changes in programming for patients deafened by bacterial meningitis and stability of auditory performance over time.', 'In this retrospective descriptive study, cochlear implant (CI) stimulation mode and performance of 14 patients deafened by meningitis were compared with those of an age-matched control group of patients deafened by other causes.', 'There were no significant differences in mean performance between the meningitis group and control group (P > 0.05). However, the postmeningitis group required progressively higher stimulation levels and higher programming modes over time as compared to the control group.\Question: Do changes in programming over time in postmeningitis cochlear implant users?

A: Even with deafness accompanied by labyrinthine ossification attributed to meningitis, neural elements were present and could be stimulated. Because increasing levels of stimulation were required over time, postmeningitic children with CIs, and those with cochlear ossification in particular, may need frequent programming adjustments to maintain performance.

Q: Context: To investigate the clinical logistics of laboratory routines at primary health care centres (PHCs).', 'Prospective registration was carried out for each PHC using questionnaires during 2-week intervals between the end of November 2001 and mid-January 2002. The study included 9 PHCs in the county of Ostergötland and 4 in the county of Jönköping, Sweden, with different numbers of blood tests analysed using point-of-care testing (POCT). Data for B-glucose, HbA1c, C-reactive protein (CRP), erythrocyte sedimentation rate (ESR), thyroid-stimulating hormone (TSH), T4, cholesterol, HDL-cholesterol, LDL-cholesterol and triglycerides were collected. Main outcome measures were median time from sampling to available test result (TATa) and median time from sampling to clinical decision (TATd), and the proportion of patients informed of the outcome of the blood test in question during the sampling occasion.', 'A total of 3542 samples were collected. The median TATa showed that B-glucose, ESR and CRP were immediately analysed at all 13 PHCs. For the other tests, TATa varied from immediately to about two days. The median TATd varied from immediately to about a week. When POCT was used, 30% of the patients were informed about the outcome of the test during the sampling occasion.\Question: Does point-of-care testing have a limited effect on time to clinical decision in primary health care?

A: POCT has a limited effect on the clinical logistics in PHCs.

Q: Context: Alloreactive NK cells play a role in tumor eradication after allogeneic HLA mismatched stem cell transplantation (SCT). The effect of NK alloreactivity in HLA identical SCT is still under debate and in particular in transplantation for chronic myeloid leukemia (CML) the data are very limited and with conflicting outcome. The aim of our study was to evaluate the effect of KIR genes and KIR ligands on leukemia free survival (LFS) and relapse rate in a well-defined, homogeneous group of CML patients phase upon HLA identical sibling SCT.', 'We retrospectively analyzed the effect of KIRs and KIR ligands (C1 and C2) on LFS and relapse in 70 CML patients in 1st chronic phase, who had received an HLA identical sibling graft. For KIR typing we used a single PCR based KIR typing protocol that also included primers allowing for the identification of the KIR binding site on HLA-Cw (AA 77 and 80).', 'The data show clear differences in transplant outcome between patients having both ligands (C1 and C2) as compared to patients having only one ligand (C1 or C2). In the latter group, the stimulatory KIR2DS5 gene was associated with improved leukemia free survival (p=0.007; hazard ratio 4.3; 95% confidence interval 1.3-6.7) and lower relapse rates (p=0.028; HR 4.3, 95% CI 1.1-9.1). In contrast, in patients carrying both ligands, KIR2DS5 was associated with reduced LFS (p=0.0056; HR 0.3; 95% CI 0.1-0.7) and higher relapse rate (p=0.02; HR 0.35, 95% CI 0.1-0.8).\Question: Is kIR2DS5 associated with leukemia free survival after HLA identical stem cell transplantation in chronic myeloid leukemia patients?

A:
Our data indicate a role for an NK mediated anti-CML response after HLA identical sibling SCT that is influenced by KIR ligands and, more importantly, by stimulatory KIRs present in the donor.
