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.

Input: Consider Input: It is a matter of debate whether or not ordinary heading of the ball in soccer causes injury to brain tissue.', 'To analyse concentrations of the biochemical markers of brain tissue damage S-100B and neurone specific enolase (NSE) in serum of female elite soccer players in association with a competitive game.', 'Venous blood samples were obtained from 44 female soccer players before and after a competitive game for analysis. The number of headers and trauma events (falls, collisions, etc) was assessed from videotape recordings for each player.', 'Concentrations of both brain damage markers were increased after the game (S-100B, 0.18 (0.11) v 0.11 (0.05) microg/l (p = 0.000); NSE, 10.14 (1.74) v 9.05 (1.59) microg/l (p = 0.001)). There was a significant correlation between changes in S-100B concentrations and both the number of headers (r = 0.430, p = 0.004) and the number of other trauma events (r = 0.517, p < 0.001).

Output: Are serum concentrations of two biochemical markers of brain tissue damage S-100B and neurone specific enolase increased in elite female soccer players after a competitive game?

Input: Consider Input: Inadequate nutrition in very-low-birthweight (VLBW) infants is known to be associated with growth failure and poor neurological outcomes. We aimed to investigate the association of early aggressive protein and energy intakes with weight gain and 18-month neurodevelopmental outcomes in VLBW infants.', "A total of 90 infants among 129 infants who survived to discharge were included and divided into two groups (early aggressive nutrition [n = 52] vs conventional nutrition [n = 38]). Clinical findings were compared between the two groups and daily protein and energy intakes were collected for the first 4 weeks of life. Multiple regression analyses tested the association between weekly protein or energy intakes and the result of each category of the Denver Developmental Screening Test II at 18 months' corrected age or weight gain.", "The early aggressive nutrition group had higher rates of normal language development and lower rates of growth failure (<10th percentile) at both 40 weeks' and 18 months' corrected age compared to the conventional nutrition group. After controlling for the confounding variables, higher first week protein and energy intakes each independently contributed to normal language development (odds ratio [95% confidence interval]; 9.4 [1.8-49.6] per 1g/kg of protein increase and 1.7 [1.1-2.8] per 10kcal/kg of energy increase). Higher first-week protein intake was associated with a higher weight at 40 weeks' corrected age (r = 0.41, P = 0.005).

Output: Does early aggressive nutrition enhance language development in very low-birthweight infants?

Input: Consider Input: Recurrence after surgery for secondary hyperparathyroidism is not infrequent. Regrowth of the residual parathyroid tissue after subtotal parathyroidectomy or of the autograft after total parathyroidectomy occurs in many cases. Supernumerary glands are also frequently cited as the offending cause and upon revisiting the neck, the surgeon may be surprised that such an obvious gland was 'missed' at the first operation. Indeed, multiple glands removed in sequential operations have been reported suggesting that they develop over time rather than being present from the start. It is possible that microscopic parathyroid 'rests' of embryological origin proliferate under the ongoing stimulus of renal failure to produce supernumerary glands after apparently adequate initial surgery for hyperparathyroidism. The aim of the present study was to determine whether such rests occur frequently or infrequently.", 'Operative details and pathology results from 60 consecutive parathyroidectomies were reviewed and the occurrence of parathyroid rests noted.', 'Parathyroid rests were found in 37% of extra parathyroidal tissues submitted for analysis. These rests were found commonly in the thymus. The potential significance of such parathyroid rests undergoing hyperplasia in response to the ongoing stimulus of renal failure and leading to recurrent hyperparathyroidism is discussed.
Output: Does embryonic parathyroid rest occur commonly and have implications in the management of secondary hyperparathyroidism?
