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.

Context: Earlier exposure to laparoscopic techniques is thought to be beneficial for medical students. Reports have demonstrated that practice improves performance in laparoscopies. In this study, we intended to evaluate whether medical students' interest in surgery is affected by the amount of practice and the performance on a laparoscopic simulator.", 'A laparoscopic simulation curriculum was introduced at Taipei Medical University, Wan-Fang Medical Center. Study participants included 36 sixth-year and 14 seventh-year students who were divided according to whether they had indicated an interest (group A) or not (group B) in surgery. The students had twice-a-week practice sessions for 2 weeks. They underwent baseline measurement (BM) before training and posttraining measurement (PTM). Self-guided practice on the simulator was allowed. The learning outcomes were assessed comparing the BM and PTM scores by using the interquartile range (IQR) test. We also tested the correlation between total score and number of self-guided practice sessions.', 'All study participants showed improvement. No differences were observed between BM and PTM scores and between 6th- and 7th-year medical students. Significant differences were found in PTM scores between groups A and B (P < .001). Analysis of variance with a post hoc test for different groups revealed that the PTMs were significantly higher for both the 6th- and 7th-year medical students in group A than for those in group B (P < .001). Total performance scores were improved with a higher number of self-guided practice sessions. Linear regression analysis demonstrated a significant correlation between the number of self-guided practice sessions and total performance score (P < .001).\Question: Does students ' Interest in Surgery affect Laparoscopic Practicing Performance?
Those clerks and interns interested in surgery who had more sessions for self-guided practice, displayed more improvement than those not interested in surgery did. Improvement in performance correlated highly with trainees' number of self-guided practice sessions.

Context: . We aimed to evaluate the effectiveness of a multifaceted intervention, targeting staff-patient communication, in improving emergency department patient satisfaction.', 'We undertook a pre- and post-intervention study in a university-affiliated emergency department, over a 12-month period. The intervention included communication workshops, a patient education film, and a patient liaison nurse. At the patient level, the patient liaison nurse ensured optimal staff-patient community communication and played a role in staff communication education. The intervention was evaluated using patient surveys (containing general and communication-specific satisfaction items scored out of 100), complaint rates, and patient liaison nurse activity data.', "A total of 321 and 545 patients returned questionnaires in the pre- and post-intervention periods, respectively. Significant improvements were observed in patients' perceptions of being 'informed about delays' [score difference, 5.3; 95% confidence interval (CI), 0.6-10.0], that 'staff cared about them as a person' (difference, 4.4; 95% CI, 0.7-8.1), the overall emergency department facility assessment (difference, 3.9; 95% CI, 0.4-7.5) and overall emergency department care (difference, 3.8; 95% CI, 0.3-7.3). Non-significant improvements were seen in all other satisfaction items. In the post-intervention period, there was a 22.5% (95% CI, 14.6-32.8) decrease in the number of complaints received and a decrease in the complaint rate of 0.7 (95% CI, -0.3 to 1.6) complaints per 1000 patients. The patient liaison nurse activities included orientation of the patient including (i) explanation of tests, procedures, and delays; (ii) communication with a range of hospital staff; and (iii) general comfort measures including analgesia quality control.\Question: Does a multifaceted intervention improve patient satisfaction and perceptions of emergency department care?
Significant improvements in a variety of patient satisfaction measures were achieved with an intervention comprising staff communication workshops, a patient education film, and a patient liaison nurse.

Context: Oxidant stress contributes to vascular injury and atherosclerosis. We hypothesized that estrogen treatment of ovariectomized rats decreases O(2)(-) by decreasing the activity of NAD(P)H oxidase and this reduction in O(2)(-) could have a vasculoprotective effect.', 'Ovariectomized rats were treated with 17-beta-estradiol E2 (0.25mg) or oil placebo for 21 days. Aorta were removed for contractility studies and O(2)(-) production was measured by lucigenin enhanced chemiluminescence (230 and 5microM). E2 treatment decreased basal O(2)(-) production but did not alter NADH or NADPH stimulated O(2)(-) production. Total p47phox and p47phox in membrane fractions of cardiac tissue were decreased, which suggests less activation of NAD(P)H oxidase in E2 treated rats. E2 did not change expression of other components of NAD(P)H oxidase in heart, lung, spleen and diaphragm. Expression of eNOS was also lower in E2 treated rats. E2 did not affect the contractile response to phenylepherine, dilation with acetylcholine, dilation with superoxide dismutase or constriction with l-NAME. This argues against changes in bioavailable NO.\Question: Does treatment with 17-beta-estradiol reduce superoxide production in aorta of ovariectomized rats?

E2 decreases activation of p47phox and O(2)(-) production by NAD(P)H oxidase. This did not affect contractile properties of the vessel, but could still potentially alter cell signaling from oxidant increasing stresses.
