Given a passage with a context and an answer, 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.

[EX Q]: Context: Old compared with young adults walk with reduced ankle and increased hip mechanical output. We examined the idea that age, leg strength, or both are related to the age-related changes in mechanical output during gait.', 'Healthy young (n = 32, age 21.5 years) and old adults (n = 32, age 76.8 years) participated in biomechanical gait analyses at 1.5 m/s and were also measured for maximal leg strength.', 'Analysis 1 confirmed previous data as old compared with young adults walked with 50 % more hip positive work and 18 % less ankle positive work. Analysis 2 showed that leg strength did not affect gait kinetics in groups of subjects with similar ages. In a weak young and a strong old group, Analysis 3 showed that old adults still walked with 23 % greater hip positive work. The group by joint interaction in Analysis 4 was suggestive of an even greater reliance on hip and less reliance on ankle work in weak compared with strong old adults.
Answer: Age and leg strength both contribute to the age-related changes in mechanical output during gait. Exercise prescription, normally targeting the knee extensors, should also involve ankle and hip muscles.
[EX A]: Do age and muscle strength mediate the age-related biomechanical plasticity of gait?

[EX Q]: Context: Many bacterial meningitis patients experience neurological or neuropsychological sequelae, predominantly deficits in short-term memory, learning, and attention. Neuropsychological symptoms after viral meningitis are observed less frequently. Sleep disturbance has been reported after both viral and bacterial meningitis.', 'To examine systematically the frequency and extent of sleep disturbance in meningitis patients.', 'Eighty six viral or bacterial meningitis (onset of acute disease at least 1 year previously) patients were examined using two standardised questionnaires (Schlaffragebogen B and the Pittsburgh Sleep Quality Index, PSQI) in conjunction with a standardised neurological examination, and compared to a control group of 42 healthy age-matched volunteers.', 'Patients after both viral and bacterial meningitis described their sleep as reduced in quality and less restful than that of healthy control subjects; both patient groups had a pathological mean PSQI total score. Impaired sleep scores after meningitis were not correlated to either the Glasgow Coma Scale or the Glasgow Outcome Scale. Moreover, no relationship between residual neurological dysfunction or depressivity and sleep quality was observed.
Answer: Impaired sleep is a long-term consequence of meningitis. Additional, so far undetermined, factors other than the severity of concomitant neurological deficits are responsible for the development of this sequela.
[EX A]: Are sleep disorders long-term sequelae of both bacterial and viral meningitis?

[EX Q]: Context: Early recognition and treatment of sepsis improves outcomes. We determined the effects of bedside point-of-care (POC) lactate measurement on test turnaround time, time to administration of IV fluids and antibiotics, mortality, and ICU admissions in adult ED patients with suspected sepsis. We hypothesized that bedside lactate POC testing would reduce time to IV fluids and antibiotics.', 'We compared 80 ED patients with suspected sepsis and a lactate level of 2 mmol/L or greater before and 80 similar patients after introduction of POC lactate measurements. Groups were compared with (2) and Mann Whitney U tests. A sample size of 80 patients in each group had 85% power to detect a 30-minute difference in time to IV fluids or antibiotics.', 'Study groups were similar in age, gender, baseline lactate levels, sepsis severity, and Sequential Organ Failure Assessment (SOFA) scores. Introduction of POC lactate was associated with significant reductions in test turnaround time (34 [26-55] vs. 122 [82-149] minutes; P < 0.001), time to IV fluids (55 [34-83] vs. 71 [42-110] minutes; P = 0.03), mortality (6% vs. 19%; P = 0.02), and ICU admissions (33% vs. 51%, P = 0.02), but not time to IV antibiotics (89 [54-156] vs. 88 [60-177] minutes; P = 0.35).
Answer: Implementation of bedside POC lactate measurement in adult ED patients with suspected sepsis reduces time to test results and time to administration of IV fluids but not antibiotics. A significant reduction in mortality and ICU admissions was also demonstrated, which is likely due, at least in part, to POC testing.
