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.

[Q]: Context: The etiology of idiopathic scoliosis remains unknown, but growth is a risk factor for progression. Growth pattern differs in children with and without scoliosis. Cartilage oligomeric matrix protein (COMP) may be associated with scoliosis and growth. We, therefore, studied COMP in children with and without idiopathic scoliosis.', 'We included 105 children, with mean age 14.4 years (range 10-16), under observation or treatment for idiopathic scoliosis, and 103 children from an age-matched population-based cohort. COMP was measured in serum at the time of inclusion. Growth velocity was estimated from repeated height measurements. T tests, analysis of covariance or linear regression were used for statistical comparisons.', 'COMP was mean (SD) 11 (5) units/liter (U/L) in children with scoliosis and 13 (5) U/L in the control cohort (p = 0.005, adjusted for sex and sampling time of the day). When patients and controls were analyzed together, high COMP was correlated with high growth velocity ( = 0.19, p = 0.003). When patients and controls were analyzed separately, COMP was correlated with growth velocity in children with scoliosis ( = 0.27, p = 0.007), but not in children without scoliosis ( = 0.02, p = 0.83) (all analyses adjusted for age, sex and sampling time). Low COMP was significantly correlated with large curve size in children with scoliosis ( = -0.29, p = 0.003), but not after adjustment for age, sex and sampling time ( = -0.16; p = 0.14).\Question: Is serum level of cartilage oligomeric matrix protein lower in children with idiopathic scoliosis than in non-scoliotic controls?
[A]: COMP was lower in children with idiopathic scoliosis than in a control cohort. In children with scoliosis, high COMP was modestly correlated with high growth velocity, but not with curve severity.

[Q]: Context: Primary pneumonic plague is a rare but often fatal form of Yersinia pestis infection that results from direct inhalation of bacteria and is potentially transmissible from person to person. We describe a case of primary pneumonic plague in a wildlife biologist who was found deceased in his residence 1 week after conducting a necropsy on a mountain lion.', "To determine cause of death, a postmortem examination was conducted, and friends and colleagues were interviewed. Physical evidence was reviewed, including specimens from the mountain lion and the biologist's medical chart, camera, and computer. Human and animal tissues were submitted for testing. Persons in close contact (within 2 meters) to the biologist after he had developed symptoms were identified and offered chemoprophylaxis.", 'The biologist conducted the necropsy in his garage without the use of personal protective equipment. Three days later, he developed fever and hemoptysis and died approximately 6 days after exposure. Gross examination showed consolidation and hemorrhagic fluid in the lungs; no buboes were noted. Plague was diagnosed presumptively by polymerase chain reaction and confirmed by culture. Tissues from the mountain lion tested positive for Y. pestis, and isolates from the biologist and mountain lion were indistinguishable by pulsed-field gel electrophoresis. Among 49 contacts who received chemoprophylaxis, none developed symptoms consistent with plague.\Question: Do primary pneumonic plague contracted from a mountain lion carcass?
[A]: The biologist likely acquired pneumonic plague through inhalation of aerosols generated during postmortem examination of an infected mountain lion. Enhanced awareness of zoonotic diseases and appropriate use of personal protective equipment are needed for biologists and others who handle wildlife.

[Q]: Context: Patients undergoing chemoradiation for head and neck squamous cell carcinoma (HNSCC) are predisposed to unplanned hospitalizations.', 'To assess the factors associated with prolonged hospitalization and its impact on patient outcomes.', 'We assessed the outcomes of patients hospitalized for 5 days or <5 days in 251 patients with advanced HNSCC who were undergoing radiotherapy during 2000-2012.', 'Patients who had been hospitalized for 5 days were more likely to be admitted for infection, acute renal failure, and/or dehydration. We found no other patient, tumor, or treatment characteristics associated with prolonged hospitalizations. Hospitalizations of 5 days were associated with a higher incidence of delays in radiotherapy (RT; odds ratio [OR], 2.49; 95% confidence index [CI], 1.09-5.69; = .03) and worse performance status after RT (OR, 5.76; 95% CI, 1.85-18.38; = .003). On multivariate analysis, hospitalization of 5 days predicted for worse local-regional control (hazard ratio [HR], 1.85; 95% CI, 1.08-3.17; = .03) and time to treatment failure (HR, 1.64; 95% CI, 1.03-2.61; = .04), and performance status after RT predicted for worse local-regional control, time to treatment failure, progression-free survival, and overall survival.\Question: Do hospitalizations of more than 5 days predict for worse outcomes after radiotherapy for head and neck cancer?
[A]:
As a retrospective review, we report only hypothesis-generating observations, which may have been affected by having incomplete patient information.
