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.

Input: Consider Input: Context: To investigate the impact of prophylactic hyperoxic ventilation with Fio2 0.6 on the physiologic limit of acute normovolemic anemia.', 'Prospective, controlled, randomized experimental study.', 'Experimental animal laboratory of a university hospital.', 'Fourteen anesthetized domestic pigs.', 'Animals were randomly ventilated with either Fio2 0.21 (group 0.21, n = 7) or Fio2 0.6 (group 0.6, n = 7), and acute anemia was induced by isovolemic blood-for-hydroxy-ethylstarch (HES) exchange using a 6% HES solution (130/0.4).', 'The blood-for-HES-exchange was continued until a sudden decrease of total body oxygen consumption indicated the onset of oxygen supply dependency (primary end point); the corresponding hemoglobin (Hb) concentration was defined as "critical" (Hb(crit)). Secondary end points were changes in myocardial function, central hemodynamics, oxygen transport, and tissue oxygenation. Compared with room air ventilation (Fio2 0.21), hyperoxic ventilation with Fio2 0.6 enabled a larger blood-for-HES-exchange (139%, 124/156) of circulating blood volume vs. 87% (68/94, p < .05), until Hb(crit) was reached (1.5 g/dL [1.4/2.1] vs. 2.4 g/dL [2.0/2.8], p < .05). At Hb 2.4 g/dL (i.e., Hb(crit) in group 0.21), animals of group 0.6 still presented with superior oxygen transport, tissue oxygenation, and hemodynamic stability. However, hemodynamic and oxygen transport variables were found deteriorated more severely at Hb 1.5 g/dL (i.e., Hb(crit) of group 0.6) compared with group 0.21 at Hb 2.4 g/dL.\Question: Does hyperoxic ventilation increase the tolerance of acute normovolemic anemia in anesthetized pigs?

Output: During cell-free volume replacement, hyperoxic ventilation with Fio2 0.6 generates a readily usable plasmatic oxygen reserve and thereby increases the tolerance toward acute normovolemic anemia.


Input: Consider Input: Context: Mild hypothermia for 72 hours is neuroprotective in newborns with moderate or severe hypoxic-ischemic encephalopathy. A core temperature of 33.5 degrees C might reduce drug clearance leading to potential toxicity. Gentamicin is nephrotoxic and ototoxic at high serum concentrations. No study has investigated the influence of 72 hours of hypothermia on serum gentamicin concentrations (SGCs) in children of any age. We aimed to compare the SGCs in encephalopathic infants who underwent intensive care with therapeutic hypothermia or normothermia.', 'Data were collected retrospectively from 2 NICUs in Bristol, United Kingdom, that offered cooling therapy within clinical trials since 1998. Eligible infants (n = 55) developed grade 2/3 encephalopathy after birth and fulfilled the entry criteria defined in the CoolCap trial. Encephalopathic infants with similar demographic values were either nursed under normothermia or 72 h-hypothermia. Once-daily gentamicin dosage (4-5 mg/kg) was administered, and trough SGC was recorded with corresponding creatinine concentrations. The time and number of omitted drug doses were noted.', 'Mean trough SGC (pre-second dose) and mean plasma creatinine concentrations for both treatment groups were similar (gentamicin: 2.19 +/- 1.7 [hypothermia] and 2.30 +/- 2.0 [normothermia] mg/L; creatinine: 115.6 +/- 42.8 [hypothermia] and 121.0 +/- 45.1 [normothermia] mumol/L). Forty percent of the trough SGCs in both groups were above the recommended trough concentration of 2.0 mg/L. A significant correlation (r(2) = 0.36) was found between high SGCs and impaired renal function assessed by raised plasma creatinine levels regardless of treatment options.\Question: Are serum gentamicin concentrations in encephalopathic infants affected by therapeutic hypothermia?

Output: Our data confirm that impaired renal function is strongly associated with high SGCs. Reduced body temperatures do not affect the clearance of gentamicin.


Input: Consider Input: Context: The EML4-ALK fusion gene is more frequently found in younger, never smoking patients with lung cancer. Meanwhile, never smokers exposed to secondhand tobacco smoke (SHS) during childhood are diagnosed at a younger age compared with never smoking patients with lung cancer who are not exposed. We, therefore, hypothesized that SHS, which can induce DNA damage, is associated with the EML4-ALK fusion gene.', 'We compared the frequency of the EML4-ALK fusion gene among 197 never smoker patients with lung cancer with and without a history of exposure to SHS during childhood at Mayo Clinic.', 'The EML4-ALK fusion gene was detected in 33% of cases from never smokers with a history of SHS exposure during childhood, whereas 47% of never smoking lung cancer cases without a history of childhood SHS exposure tested positive for the fusion gene.\Question: Is evidence that the lung Adenocarcinoma EML4-ALK fusion gene caused by exposure to secondhand tobacco smoke during childhood?


Output: The EML4-ALK fusion gene is not enriched in tumors from individuals exposed to SHS during childhood.
