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.

Ex Input:
Context: Sepsis is an emergency condition with high mortality and morbidity rate. There are limited data on the association of cancer as a risk factor for mortality in sepsis patients in the emergency department (ED).', 'This retrospective study was conducted at the ED, Faculty of Medicine, Ramathibodi Hospital, Bangkok, Thailand. The study period was between January 1st and December 31st, 2014. The inclusion criteria were as follows: adult patients over 15 years of age who presented at the ED with suspicion of sepsis, received treatment at the ED, and whose blood culture was found to be positive. Clinical data were recorded from medical records including the Mortality in Emergency Department Sepsis score (MEDS score). The primary outcome of this study was mortality at one month. Multivariate logistic regression analysis was used to identify independent factors associated with death.', 'During the study period, there were 775 eligible patients. The two most common pathogens identified from blood cultures were Staphylococcus aureus (193 patients; 24.9%) and Escherichia coli (158 patients; 20.4%). At one month after presenting at the ED, 110 patients (14.2%) had died. There were four significant factors for death, having cancer, being on an endotracheal tube, initial diagnosis of bacteremia, and high MED scores. Having cancer had an adjusted OR of 2.12 (95% CI of 1.29, 3.47).\Question: Do cancer Patients Are at High Risk of Mortality if Presenting with Sepsis at an Emergency Department?

Ex Output:
Cancer patients have double the risk of mortality if presenting with sepsis at the ED.


Ex Input:
Context: Ventriculo-peritoneal shunting is the most commonly used method for the treatment of paediatric hydrocephalus. The programmable valve with the ability to adjust the opening pressure non-invasively has made it easier to find exactly the right opening pressure for each child and reduce the risk of over- or under-drainage. The aim of this investigation was to study our clinical experience with the adult Codman Hakim programmable valve in children, with reference to complications and economic impact.', 'A seven-year retrospective study of 122 hydrocephalic children (aged from children born prematurely to 15 years old) shunted with the adult Codman Hakim programmable valve was performed.', 'The programmable valve was the first shunt in 76 children and in 14 after prior ventricular drainage. The remaining 46 had different non-programmable systems as their first shunt. The most common reason for changing to a programmable valve was over-drainage. With the programmable valve, catheter-related complications, e.g. proximal (36%) or distal obstructions (30%), were the main reasons for surgical revision. Non-invasive pressure adjustment was performed in 73% of the children. Among the children with the programmable valve as their first shunt, 57 (75%) were adjusted, 12 (21%) had severe symptoms of over-drainage and would have required urgent surgical change of the valve if it had not been adjustable. A resetting of the opening pressure after MRI was found in 38% and accidental resetting occurred in 4%. Programmable valves are about twice as expensive as non-programmable valves. We estimated the increased cost of the valve and compared it with the savings from a reduction in the number of re-operations. The total cost for the programmable valve (as the primary shunt) in our study was less than that for expected re-operations due to over- or under-drainage when using non-programmable valves.\Question: Is the programmable adult Codman Hakim valve useful even in very small children with hydrocephalus . A 7-year retrospective study with special focus on cost/benefit analysis?

Ex Output:
The programmable valve was easy to handle; only one size was required and the adjustment made it possible to achieve an optimal intraventricular pressure with a lower total cost, reduced hospital stay as well as an increased quality of life for the children.


Ex Input:
Context: Acute kidney injury (AKI) is common after liver transplantation (OLT) and is associated with high morbidity and mortality. Previous studies have shown that interleukin-18 (IL-18) levels are associated with AKI. The purpose of this study was to determine whether plasma IL-18 levels were early predictors for AKI after liver transplantation.', 'Plasma samples were obtained from 26 patients who underwent OLT at induction of anesthesia (T1), 1 hour after the surgical incision (T2), the time of reperfusion (T3), as well as 1 (T4), 2 (T5), and 4 hours (T6) after reperfusion. Samples were also obtained at 24 hours after surgery (T7). The AKI criteria were taken according to the Acute Kidney Injury Network criteria.', 'Twelve patients (46%) developed AKI after OLT. The area under the receiver operating curve of plasma IL-18 concentrations (T4/T1) to predict AKI occurrence was 0.842 at T5, 0.905 at T6, 0.726 at T7, and 0.726 at T5 to T7.\Question: Is the ratio of plasma interleukin-18 a sensitive biomarker for acute kidney injury after liver transplantation?

Ex Output:

Plasma IL-18 concentrations taken 1 hour after reperfusion were predictive of AKI. Therefore, changing IL-18 ratio may be an early predictor for AKI after OLT.
