Given a passage with a context and an answer, construct a question on the basis of the information present in the passage. Construct the question in such a way that (i) it is unambiguous, (ii) it is answerable from the passage, (iii) its answer is unique (iv) it answer uses text phrases from the passage. Avoid creating questions that (i) can't be answered correctly without actually understanding the passage and (ii) uses the same words or phrases given in the passage.

Input: Consider Input: Context: It has been hypothesized that minichromosome maintenance (MCM) proteins, which are replicative control factors, can be used to detect tumor proliferation. The aim of the present study was to investigate the expression of MCM in colorectal cancer tissues and correlate it to clinical outcomes.', 'The study included 145 patients with colorectal cancer who underwent curative surgery, from January 2002 until December 2004, at the Kurume University Hospital in Fukuoka, Japan. The median follow-up duration was 87 months. The expression of MCM7 in tissues was studied by immuno-histochemical staining. The labeling index (LI) of MCM7 was calculated by dividing the number of positively-stained cells by the total number of cells counted. We divided samples into two groups: positive (MCM7 LI 76% or higher) and negative (MCM7 LI less than 76%).', 'In patients with Dukes A and B, there were no significant differences in either overall survival (OS) or recurrence-free survival (RFS) between patents with MCM7-positive and those with MCM7-negative disease. On the other hand, in patients with Dukes C, there was significantly worse OS and RFS for patients with MCM7-positive compared to those with MCM7-negative disease.
Answer: We found that the expression of MCM7 is an independent risk factor for RFS in patients with Dukes C colorectal cancer. Further studies are required to investigate the validity of MCM7 protein expression for its potential clinical use in colorectal cancer therapy and prognosis.

Output: Is minichromosome maintenance protein 7 a risk factor for recurrence in patients with Dukes C colorectal cancer?


Input: Consider 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).
Answer: Cancer patients have double the risk of mortality if presenting with sepsis at the ED.

Output: Do cancer Patients Are at High Risk of Mortality if Presenting with Sepsis at an Emergency Department?


Input: Consider Input: Context: Minute ventilation (MV) has been proven to be very useful in rate responsive pacing. The aim of this study was to evaluate the feasibility of using implantable cardioverter-defibrillator (ICD) leads as part of the MV detection system.', 'At implant in 10 patients, the transthoracic impedance was measured from tripolar ICD, tetrapolar ICD, and atrial lead vectors during normal, deep, and shallow voluntary respiration. MV and respiration rate (RespR) were simultaneously measured through a facemask with a pneumotachometer (Korr), and the correlations with impedance-based measurements were calculated. Air sensitivity was the change in impedance per change in respiratory tidal volume, ohms (Omega)/liter (L), and the signal-to-noise ratio (SNR) was the ratio of the respiratory and cardiac contraction components.', 'The air sensitivity and SNR in tripolar ICD vector were 2.70 +/- 2.73 ohm/L and 2.19 +/- 1.31, respectively, and were not different from tetrapolar. The difference in RespR between tripolar ICD and Korr was 0.2 +/- 1.91 breaths/minute. The regressed correlation coefficient between impedance MV and Korr MV was 0.86 +/- 0.07 in tripolar ICD.
Answer: The air sensitivity and SNR in tripolar and tetrapolar ICD lead vectors did not differ significantly and were in the range of the values in pacemaker leads currently used as MV sensors. The good correlations between impedance-based and Korr-based RespR and MV measurements imply that ICD leads may be used in MV sensor systems.


Output: Does acute evaluation of transthoracic impedance vectors using ICD lead?
