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 Q]: Context: Oral tacrolimus, approved for the prophylaxis of organ rejection in liver or kidney transplants, has been reported to be effective in anecdotal cases of refractory inflammatory bowel disease.', 'To evaluate the usefulness of low-dose oral tacrolimus in refractory inflammatory bowel disease.', "Thirty-one adult Caucasian patients with steroid-dependent (n = 15) or steroid-refractory (n = 16) inflammatory bowel disease (Crohn's disease, n = 6; ulcerative colitis, n = 23; pouchitis, n = 2) were enrolled. Tacrolimus (0.1 mg/kg body weight per day) was administered orally in 30 patients and initially intravenously in one patient (0.01 mg/kg body weight per day), aiming for serum trough levels of 4-6 ng/mL. The median treatment duration was 12 months (range, 1-137 months).", "Twenty-eight patients (90.3%) experienced a clinical and laboratory response and 20 (64.5%) went into remission. One ulcerative colitis patient and two Crohn's disease patients did not improve. Three ulcerative colitis patients (9.7%) were colectomized at 1, 12 and 24 months after tacrolimus initiation. In 19 of 23 patients (82.6%) taking steroids, steroids were reduced or discontinued. Side-effects included a temporary rise of creatinine (n = 3, 9.7%), tremor or paraesthesias (n = 3, 9.7%), hyperkalaemia (n = 1, 3.2%), hypertension (n = 1, 3.2%) and an opportunistic infection (n = 1, 3.2%).\Question: Is rescue therapy with tacrolimus effective in patients with severe and refractory inflammatory bowel disease?
[EX A]: Oral tacrolimus is safe and effective in refractory inflammatory bowel disease.

[EX Q]: Context: Although N-terminal pro-B-type natriuretic peptide (NT-proBNP) has a strong relationship with incident cardiovascular disease (CVD), few studies have examined whether NT-proBNP adds to risk prediction algorithms, particularly in women.', 'This study sought to evaluate the relationship between NT-proBNP and incident CVD in women.', "Using a prospective case-cohort within the WHI (Women's Health Initiative) observational study, we selected 1,821 incident cases of CVD (746 myocardial infarctions, 754 ischemic strokes, 160 hemorrhagic strokes, and 161 other cardiovascular [CV] deaths) and a randomly selected reference cohort of 1,992 women without CVD at baseline.", 'Median levels of NT-proBNP were higher at study entry among incident cases (120.3 ng/l [interquartile range (IQR): 68.1 to 219.5 ng/l]) than among control subjects (100.4 ng/l [IQR: 59.7 to 172.6 ng/l]; p\xa0< 0.0001). Women in the highest quartile of NT-proBNP (≥140.8 ng/l) were at 53% increased risk of CVD versus those in the lowest quartile after adjusting for traditional risk factors (1.53 [95% confidence interval (CI): 1.21 to 1.94]; p for trend\xa0<0.0001). Similar associations were observed after adjustment for Reynolds Risk Score covariables (1.53 [95% CI: 1.20 to 1.95]; p for trend\xa0<0.0001); the association remained in separate analyses of CV death (2.66 [95% CI: 1.48 to 4.81]; p for trend\xa0<0.0001), myocardial infarction (1.39\xa0[95% CI: 1.02 to 1.88]; p for trend\xa0= 0.008), and stroke (1.60 [95% CI: 1.22 to 2.11]; p for trend\xa0<0.0001). When added to traditional risk covariables, NT-proBNP improved the c-statistic (0.765 to 0.774; p\xa0= 0.0003), categorical net reclassification (0.08; p\xa0< 0.0001), and integrated discrimination (0.0105; p\xa0<\xa00.0001). Similar results were observed when NT-proBNP was added to the Reynolds Risk Score.\Question: Do b-type natriuretic peptides improve cardiovascular disease risk prediction in a cohort of women?
[EX A]: In this multiethnic cohort of women with numerous CV events, NT-proBNP modestly improved measures of CVD risk prediction.

[EX Q]: Context: Nasal vaccination is an effective therapeutic regimen for preventing otitis media. Since cholera toxin (CT) is toxic, an alternative adjuvant is required for the development of a nasal vaccine. The efficacy of CpG oligodeoxynucleotide (ODN) as a mucosal adjuvant was examined.', 'Mice were immunized intranasally with P6 protein of non-typeable Haemophilus influenzae (NTHi) and adjuvant, CT, or CpG ODN, and P6-specific antibody responses were examined. The expression of P6-specific cytokine mRNA in splenic CD4 T cells was also determined. In addition, NTHi challenges were performed and the NTHi was quantified in nasal washes.', 'P6-specific IgA in nasal wash and serum IgG titers were elevated significantly after nasal immunization. The IgG1/IgG2a ratio in serum from P6+CpG-immunized mice was less than that of P6+CT-immunized mice. Although IL-6 was expression similarly in both groups, IFN-gamma expression was greater in P6+CpG-immunized mice than in P6+CT-immunized mice. Enhanced clearance of NTHi from the nasopharynx was also shown equally in both groups.\Question: Does nasal vaccination with CpG oligodeoxynucleotide induce protective immunity against non-typeable Haemophilus influenzae in the nasopharynx?
[EX A]:
These results indicate that CpG ODN might be an effective mucosal adjuvant, acting by mechanisms that are different from CT. These findings suggest that nasal vaccination with P6 and CpG ODN might be an effective regimen for the induction of NTHi-specific protective immunity.
