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.

To test the effect of substituting a modified-fat cheese product into the diets of hypercholesterolemic adults.', 'A 4-month, randomized, double-blind, crossover substitution trial.', 'General community outpatient study.', 'Twenty-six healthy adult volunteers (17 men, 9 women) with moderate hypercholesterolemia (total cholesterol > 5.69 mmol/L but < 7.24 mmol/L).', "Daily substitution of 100 g of cheese, either partial skim-milk mozzarella or modified-fat (vegetable oil) mozzarella cheese product, into participants' normal diets. Participants consumed an assigned cheese for 2 months, at which time they crossed over to consume the other study cheese.", 'Plasma lipid and apolipoprotein levels were measured at baseline and at 2 and 4 months after initiation of the study. Compliance was assessed by body weight and by biweekly dietary records and interviews.', 'No differences in weight or in the amount or type of calories consumed were found during the study. No statistically significant changes in lipid values resulted from consumption of mozzarella cheese. Modified-fat cheese substitution resulted in a decreased low-density lipoprotein cholesterol level when compared with levels at both baseline (-0.28 mmol/L; 95% Cl, -0.14 to -0.42 mmol/L) and during consumption of the skim-milk mozzarella cheese (-0.38 mmol/L; 95% Cl, -0.2 to -0.70 mmol/L). Findings for total cholesterol were similar. High-density lipoprotein cholesterol, plasma triglyceride, and apolipoprotein A-l and B-100 levels were unaltered. Both sexes responded similarly.
Does a linoleate-enriched cheese product reduce low-density lipoprotein in moderately hypercholesterolemic adults?

There is insufficient knowledge of infectious risk in patients after splenectomy; minimal data exists specifically for trauma patients. This study evaluated patient knowledge and practices regarding infection risk after traumatic splenectomy. Our hypothesis was that patients with poor knowledge regarding their asplenic state would be less likely to pursue medical care in the event of an illness than those with good knowledge.', 'Non-randomized, cohort study of all posttraumatic splenectomy patients < or =11 years after injury in 2 rural trauma centers. Patients received a validated questionnaire; weighted responses determined knowledge about infection risks and appropriate follow-up actions.', 'Fifty-four percent of patients responded to the questionnaire. Overall, 47% of responders were identified as having adequate knowledge regarding infectious risk, and only 28% would pursue appropriate medical care. Of patients with adequate knowledge, 42% were more likely to pursue appropriate care versus 15% of patients with inadequate knowledge (p = 0.06). Patients with adequate knowledge were more likely to receive an annual influenza vaccine (p = 0.03) and contact their provider with fewer symptoms (p = 0.03). Logistic regression revealed significant interactions between knowledge and presence of comorbidities (p = 0.04). Focusing on patients with poor knowledge and absence of comorbidities, none would engage in appropriate action in the event of illness (p < 0.01). A longer time since injury, >3 years, was associated with a diminished likelihood of appropriate action (p = 0.03). The relationship between knowledge and action was not accounted for by other potential confounders.
Do time lapse and comorbidities influence patient knowledge and pursuit of medical care after traumatic splenectomy?

To assess the ability of an adult risk screening questionnaire (RSQ), previously shown to predict attendance at hospital emergency departments, to identify impaired quality of life in adult patients with asthma in general practice.', 'Baseline data from an RCT of asthma clinics in general practice, using the St. George Respiratory Questionnaire (SGRQ) to measure quality of life.', 'Twelve general practices in Adelaide, Australia.', 'A total of 184 adult asthmatics were recruited, with a mean (standard deviation) age of 50.3 years (16.6 years). Age, gender, weight, number of comorbidities, smoking status, FEV1 and percent predicted FEV1 (pre-and post-bronchodilator), peak flow (pre and post), and RSQ were independently related to SGRQ scores. After adjusting for potential confounders, an RSQ score predictive of hospital attendance was also associated with an average increase (worsening) in SGRQ total score of 11.9 (95% CI: 7.6, 16.3), an average increase in activity score of 9.0 (2.5, 15.5), symptom score of 14.8 (8.6, 21.0), and impact score of 13.1 (8.6, 17.6). These represent clinically significant differences.
Does hospital attendance prediction tool also identify impaired quality of life in adults with asthma in general practice?
