Given a passage, construct a question on the basis of the information present in the passage. Construct the question in such a way that (i) it is unambiguous, (ii) it is answerable from the passage, (iii) its answer is unique (iv) it answer uses text phrases from the passage. Avoid creating questions that (i) can't be answered correctly without actually understanding the passage and (ii) uses the same words or phrases given in the passage.

Q: Toenail onychomycosis is a common disease that can have serious adverse effects on the quality of life (QOL) of patients.', 'To evaluate the impact of itraconazole pulse therapy on the QOL of patients with toenail onychomycosis.', 'A total of 20 patients with disto-lateral subungual toenail onychomycosis were treated with itraconazole 200 mg twice daily for 1 week every 4 weeks for 12 weeks. The patients were asked to complete a QOL questionnaire before treatment and on the last follow-up visit (week 48). A score of 0-4 was given according to the five possible responses to each question and these were summed to give the final score of the patient. The mean of the final scores of the patients before and after treatment were compared using the Wilcoxon matched-pairs test.', 'At 48 weeks after commencing treatment, 14 patients (70%) responded to treatment (nine patients were cured with almost totally clear toenails and five patients improved), and 16 patients (80%) were mycologically cured (negative KOH smear and culture). The mean of the QOL scores of the patients before treatment was 18.0+/-7.8, which reduced to 13.1+/-11.3 after treatment (two-tailed, p=0.009).

A: Does itraconazole pulse therapy improve the quality of life of patients with toenail onychomycosis?

Q: Cadherins are calcium-dependent cell-to-cell adhesion glycoproteins playing a critical role in the formation and maintenance of normal tissue architecture. In normal mammary gland, E-cadherin is expressed by luminal epithelial cells, while P-cadherin is restricted to myoepithelial cells. Changes in the expression of classical E- and P-cadherins have been observed in mammary lesions and related to mammary carcinogenesis. P-cadherin and E-cadherin expressions were studied in a series of feline normal mammary glands, hyperplastic/dysplastic lesions, benign and malignant tumours by immunohistochemistry and double-label immunofluorescence.', 'In normal tissue and in the majority of hyperplastic/dysplastic lesions and benign tumours, P-cadherin was restricted to myoepithelial cells, while 80% of the malignant tumours expressed P-cadherin in luminal epithelial cells. P-cadherin expression was significantly related to high histological grade of carcinomas (p <0.0001), tumour necrosis (p = 0.001), infiltrative growth (p = 0.0051), and presence of neoplastic emboli (p = 0.0401). Moreover, P-cadherin positive carcinomas had an eightfold likelihood of developing neoplastic emboli than negative tumours. Cadherins expression profile in high grade and in infiltrative tumours was similar, the majority expressing P-cadherin, regardless of E-cadherin expression status. The two cadherins were found to be co-expressed in carcinomas with aberrant P-cadherin expression and preserved E-cadherin.

A: Is aberrant P-cadherin expression associated to aggressive feline mammary carcinomas?

Q: To investigate the factors related to communications in home medical care settings, and the association between such factors and a patient's place of death.", 'A questionnaire survey of 295 families of patients who had previously received home medical care was carried out in June and July 2011. The response rate was 83.8% (n\u2009=\u2009227). Following the exclusion of families where the patient was still alive, or where the place of death was unknown, 143 questionnaires were available for analysis. Logistic regression was used to identify significant associations between possible factors related to communication and occurrence of home death.', "Home death was observed in 66.4% (n\u2009=\u200995) of the families analyzed. Home death was significantly associated with the frequency of doctor home-visits per week (OR 2.835, 95% CI 1.436-5.597, P\u2009=\u20090.003). There was no statistically significant association between home death and any of the other variables included: malignant tumors as primary disease, independence in daily activity, duration of home medical care, duration of doctor's visits, experience of doctor-patient communication without family, doctor-family communication without the patient or explanation from the doctor on the phone, existence of home-visit nursing services, existence of family's anxieties and/or questions, age of primary caregiver(s) and sex of primary caregiver(s).

A:
Is home death associated with frequency of physician home medical care visits : a questionnaire survey on communications in home medical care settings?
