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: A family is described in which the father and three (and probably all four) of his children had a decreased capacity for the oxidation of medium-chain fatty acids. One of the children suddenly died at the age of 16 months following an episode of a rapidly deteriorating Reye syndrome-like illness with hypoketotic hypoglycemia and dicarboxylic aciduria, but without any previous alarming symptoms. The eldest sibling had died at the age of 19 months under similar conditions. The other family members had always been healthy. On fasting, all affected family members accumulated in their plasma the medium-chain fatty acids octanoic, decanoic, and cis-4-decenoic acids. Their urinary organic acid excretion profile could be characterized as "dicarboxylic aciduria." A deficiency of medium-chain acyl-coenzyme A dehydrogenase was demonstrated in a postmortem liver sample of the index patient. Cultured fibroblasts from the father and the two healthy children had a decreased rate of [14C]octanoate oxidation. It is suggested that a deficiency of medium-chain acyl-coenzyme A dehydrogenase may lead to a life-threatening illness when other complicating factors such as diarrhea and vomiting result in an abnormal depletion of the body's glycogen stores. Careful monitoring of at-risk patients during a minor illness is necessary.
