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.

Question: We investigated the effects of pulsed ultrasound on swelling, muscle soreness perception, relaxed-elbow extension angle, and muscular strength.', 'Eight sets of concentric and eccentric actions induced delayed-onset muscle soreness of the elbow flexors. Group 1 received 20% pulsed ultrasound treatments (1-MHz, 7 minutes, 1.5 W/ cm(2) temporal peak intensity) twice a day immediately after postexercise assessments and at 3, 24, 27, 48, 51, 72, and 75 hours postexercise. Group 2 received sham treatments immediately after postexercise assessments and at 3,27, 51, and 75 hours postexercise and true treatments of pulsed ultrasound at 24, 48, and 72 hours postexercise. Group 3 received sham treatments of no ultrasonic output immediately after postexercise assessments and at 3, 24, 27, 48, 51, 72, and 75 hours postexercise.', 'Thirty-six college-age females.', 'We recorded upper-arm circumference, perceived soreness, relaxed-elbow extension angle, and elbow-flexion strength before (pretest), immediately postexercise, and at 24, 48, 72, and 96 hours postexercise.', 'We noted differences over time but no treatment effect between groups or interactions between time and group for upper-arm circumference, perceived soreness, relaxed-elbow extension angle, or elbow-flexion strength.

Answer: Does pulsed ultrasound fail to diminish delayed-onset muscle soreness symptoms?


Question: Smoking is an important risk factor for cardiovascular disease. Sympathetic responses to cigarette smoking may be implicated in the link between smoking and cardiovascular disease. We tested the hypothesis that the sympathetic neural responses to smoking are age dependent.', 'We examined the effects of cigarette smoking and sham smoking on muscle sympathetic nerve activity, blood pressure and heart rate in 14 normotensive middle-aged (49 +/- 4 years) and 12 young (29 +/- 4 years) habitual smokers matched for body mass index (25 +/- 2 kg/m2 in both groups).', 'Sham smoking had no significant effect on sympathetic drive, blood pressure or heart rate in either group. Cigarette smoking increased heart rate in both middle-aged subjects and young subjects. In comparison to younger subjects, middle-aged smokers showed similar smoking-related increases in systolic blood pressure (SBP) [10 +/- 3 versus 12 +/- 2 mmHg, respectively, not significant (NS)]. Smoking decreased sympathetic nerve activity by 28 +/- 12% of baseline values (P < 0.01) in young subjects. However, muscle sympathetic nerve activity did not change significantly after smoking in middle-aged subjects (5 +/- 8%, NS), despite the increased blood pressures, which would be expected to inhibit sympathetic activity. By contrast, in young subjects, the heart rate increase (22 +/- 2 bpm) was greater than that seen in middle-aged subjects (13 +/- 2 bpm, P < 0.01).

Answer: Are sympathetic neural responses to smoking age dependent?


Question: There is little information in the literature regarding the use of health care services by workers with occupational contact dermatitis.', 'The objective of the study was to describe the use of health care services by workers with occupational contact dermatitis.', "One hundred workers with hand dermatitis were enrolled and observed for 6 months after assessment at St. Michael's Hospital (Toronto, ON, Canada). Information was collected at the time of diagnosis and 6 months after the assessment. Questionnaires were administered to collect information about clinical presentation and the use of health services.", "A diagnosis of occupational contact dermatitis was made for 78 of the workers. By the time of assessment at the Occupational Health Clinic at St. Michael's Hospital, almost all of the workers had seen their family doctor for their skin problem, and 71% had seen a dermatologist. Although family doctors and dermatologists asked the workers to identify their occupation, they rarely asked about workplace exposures, and the physicians provided minimal advice about job change or modification on return to work. During the 6 months following diagnosis, 62% of the workers saw their family physicians in follow-up, but rarely was advice about job change or modification provided at these follow-up visits.

Answer:
Do health care services use by workers with work-related contact dermatitis?
