Given an abstract, generate a keyword (a noun phrase) that best describes the focus or contribution of the paper. Such keywords can be directly from the given abstract or outside it.
One example is below.
Q: Abstract: Some patients converted from ventricular fibrillation to organized rhythms by defibrillation - trained ambulance technicians(EMT - Ds) will refibrillate before hospital arrival.The authors analyzed 271 cases of ventricular fibrillation managed by EMT - Ds working without paramedic back - up.Of 111 patients initially converted to organized rhythms, 19(17 % ) refibrillated, 11(58 % ) of whom were reconverted to perfusing rhythms, including nine of 11(82 % ) who had spontaneous pulses prior to refibrillation.Among patients initially converted to organized rhythms, hospital admission rates were lower for patients who refibrillated than for patients who did not(53 % versus 76 % , P = NS), although discharge rates were virtually identical(37 % and 35 % , respectively).Scene - to - hospital transport times were not predictively associated with either the frequency of refibrillation or patient outcome.Defibrillation - trained EMTs can effectively manage refibrillation with additional shocks and are not at a significant disadvantage when paramedic back - up is not available.
A: Ventricular Fibrillation
Rationale: This term is directly present in the abstract and it is one of the main topic in it. So can be chosen as the medical subject heading.
Q: Abstract: We conducted a randomized trial comparing a high (120 mg/m2 day 1) v a standard (60 mg/m2 day 1) dose of cisplatin in combination with etoposide (120 mg/m2 days 3, 5, and 7) in advanced non-small-cell lung carcinoma (NSCLC). Two hundred forty-one patients were evaluable for survival and 207 for response. We obtained a 25% objective response rate in the standard-dose arm and 29% in the high-dose arm; this difference was not statistically significant. There was no significant improvement in the overall survival or survival of responders with the high-dose regimen. However, toxicity (mainly myelosuppression) was significantly increased in the patients receiving the higher dose of cisplatin. An analysis of prognostic factors showed that disease progression, loss of body weight, performance status, and prior therapy were predictive parameters of survival.
