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: To determine whether macrophages in human reproductive tissues contain luteinizing hormone (LH)/human chorionic gonadotropin (hCG) receptor mRNA and receptor protein that can bind 125I-hCG.', 'Macrophages isolated from term pregnancy human decidua were used for LH/hCG receptor detection by in situ hybridization for receptor mRNA and immunocytochemistry for a macrophage marker, CD68, performed alone and in combination, reverse transcription-nested polymerase chain reaction, Western and ligand blotting. The LH/hCG receptor presence in macrophages in late luteal phase human endometria and corpora lutea was determined by sequential performance of in situ hybridization and immunocytochemistry.', 'The macrophages present in term pregnancy human decidua and late luteal phase human endometria and corpora lutea contain LH/hCG receptors.\Question: Do macrophages in human reproductive tissues contain luteinizing hormone/chorionic gonadotropin receptors?
[A]: This is the first demonstration of macrophages present in human reproductive tissues containing LH/hCG receptors. The receptor presence suggests that LH and hCG may regulate macrophage functions in gonadal as well as in non-gonadal target tissues.

[Q]: Context: Studies on the safety of aprotinin in coronary artery surgery have given conflicting results. Therefore, we studied the possible link between perioperative aprotinin treatment and renal dysfunction in patients undergoing first-time coronary surgery with a high risk of bleeding.', 'We performed a matched cohort study, comparing 200 patients receiving high-dose aprotinin with 200 patients receiving tranexamic acid during primary isolated coronary surgery. Patients were matched according to age, sex, and presence of acute coronary syndrome. Primary outcome was fractional change in creatinine clearance. Secondary outcomes were other evaluations of postoperative renal function, mortality, stroke, reoperation for bleeding, and transfusion requirements.', 'The groups were similar in baseline characteristics except that triple-vessel disease and history of myocardial infarction were more prevalent in the aprotinin group. No significant differences were found in fractional change in creatinine clearance (-11% versus -12%, medians, p = 0.75) or any other assessments of postoperative renal function between the tranexamic acid and the aprotinin group. Adverse event rates were similar: early mortality (3.5% versus 4.5%, p = 0.80), stroke (1.5% versus 2%, p = 1.0), reoperation for bleeding (3.5% versus 2.5%, p = 0.77), and 5-year survival (87% versus 84%, p = 0.17). Patients in the aprotinin group received fewer transfusions (48% versus 60.5%, p = 0.02), fewer units of packed red blood cells (2.0 versus 1.4, p = 0.02) and plasma (1.3 versus 0.5, p < 0.001), but more units of platelets (0.1 versus 0.2, p = 0.02).\Question: Is aprotinin associated with postoperative renal impairment after primary coronary surgery?
[A]:
Aprotinin treatment during primary coronary surgery was not associated with impaired postoperative renal function in comparison with patients treated with tranexamic acid.
