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: The aim of this study was to investigate the attitudes and perceptions of staff radiologists regarding the incorporation of a nonanonymous peer review system at an academic hospital.', 'A questionnaire gauging knowledge of, attitudes toward, and perceptions regarding peer review was distributed to all staff radiologists at a large academic hospital. The survey was distributed before the implementation of a nonanonymous peer review system. Data were analyzed using descriptive statistics. Responses were cross-tabulated according to subspecialty and number of years in practice.', 'The majority of respondents agreed that peer review is important for improving patient care (31 of 36 [86%]) and professional development (29 of 36 [81%]), but the vast majority (33 of 36 [92%]) believed that peer review should be anonymous. Twenty-six of 36 respondents (72%) believed that peer review will not be safe from malpractice issues, 24 of 36 (67%) agreed that it has the potential to damage interpersonal relationships within the department, and 15 of 36 (42%) believed that it may influence their job security or rankings within the department. Significant differences were identified between radiologists with more and fewer years of practice experience.\Question: Do survey of radiologist attitudes and perceptions regarding the incorporation of a departmental peer review system?

A: The incorporation of a nonanonymous peer review system generates anxiety and uncertainty within a radiology department. The investigation of physicians' attitudes toward and perceptions about peer review is important for understanding the potential impact not only on patient care but also on radiologists' relationships and psychology in the workplace.

Q: Context: The aim of this prospective, randomized, double-blind study was to compare two doses of intranasal sufentanil for postoperative analgesia, titrated according to individual requirements based upon a numeric rating scale (NRS) from 0 to 10 for pain.', 'Forty patients, American Society of Anesthesiologists physical status I-II, scheduled for herniorrhaphy or hemorrhoidectomy under general anesthesia, were included when postoperative NRS was > 3. Nurses used a nasal puff device delivering a constant volume. Patients were randomized into two groups: Group A patients received a dose of 0.025 microg x kg(-1) /puff, Group B patients a dose of 0.05 microg x kg(-1) /puff. Puffs were administered as often as needed to obtain NRS < or = 3, with an interval time of five minutes. Hemodynamic, respiratory measures and sedation were recorded every five minutes.', 'The probability of persistence of pain in Group B was consistently lower than in Group A. After 20 min, 20% of the patients had a NRS score > 3 in Group B, as opposed to 60% in Group A. At 60 min, no patient had a NRS > 3 in Group B, whereas there was a probability of 20% to record a NRS > 3 for Group A. Hemodynamic, respiratory parameters and sedation remained stable with no intergroup differences.\Question: Is intranasal sufentanil effective for postoperative analgesia in adults?

A: Nasal administration of 0.050 microg x kg(-1) /puff sufentanil allowed a NRS < 4 to be attained within one hour in all patients, with efficacy achieved after 20 min. These findings suggest that the intranasal route is an effective mode of sufentanil administration for immediate postoperative analgesia in adult patients.

Q: Context: The gold standard for the diagnosis of Hirschsprung's disease (HSCR) is the pathologic evaluation of a rectal biopsy that demonstrates the absence of ganglion cells and nerve fibre hypertrophy. However, it has been frequently reported that hypertrophic nerves may not be present in some variants like long-segment HSCR, total colonic aganglionosis, premature and very young infants. The aim of this study was to determine this association.", "We performed a retrospective review of the HSCR database at our tertiary care children's hospital from 2000 to 2013. In order to analyse the relationship between the diameter of the nerve fibres and the level of aganglionosis, we classified the patient sample into two groups-fibres 40 and >40m. The groups were statistically compared with P<0.05 being significant.", 'Rectal biopsies of 92 patients confirmed as HSCR with definitive operation performed at the same institution were reviewed. The mean nerve diameter was 50.1m (range 20-87.5m). Nerve fibre diameter 40m was predictive of transition zone above the sigmoid colon. A specificity of 77.3% and a likelihood ratio of 2.03 supported this perception. No correlation was noted between nerve fibre diameter and gestational age at birth, birth weight or age at biopsy.\Question: Does aganglionosis with the absence of hypertrophied nerve fibres predict disease proximal to rectosigmoid colon?

A:
The absence of nerve fibre hypertrophy in the presence of aganglionosis on rectal biopsy specimens is predictive of long-segment HSCR.
