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.

Example Input: Context: Efforts to improve outcomes from acute kidney injury (AKI) have focussed on timely diagnosis and effective delivery of basic patient care. Electronic alerts (e-alerts) for AKI have attracted interest as a tool to facilitate this. Initial feasibility has already been demonstrated; this review will discuss recent advances in alert methodology, implementation beyond single centres and reported effect on outcomes.', 'On-going descriptions of e-alerts highlight increasing variation in both detection algorithms and alert processes. In England, this is being addressed by national rollout of a standardized detection algorithm; recent data have shown this to have good diagnostic performance. In critical care, fully automated detection systems incorporating both serum creatinine and urine output criteria have been developed. A recent randomized trial of e-alerts has also been reported, in which isolated use of a text message e-alert did not affect either clinician behaviour or patient outcome.\Question: Does recent developments in electronic alert for acute kidney injury?
Example Output: As e-alerts gain popularity, consideration must be given to both the method of AKI detection and the method by which results are communicated to end-users; these aspects influence the degree of these systems' effectiveness. This approach should be coupled to further work to study the effect on patient outcomes of those interventions that have been demonstrated to influence clinician behaviour.

Example Input: Context: Although the C5 variant of cholinesterase is known to be a cause of hypercholinesterasemia, the pathophysiological significance of the C5 variant and the C5 variant-related hypercholinesterasemia in cardiovascular diseases remain unclear. The present study aimed to clarify the pathophysiological significance of the C5 variant as a risk or protective factor for coronary artery disease (CAD) in patients with severe hypercholinesterasemia.', 'Severe hypercholinesterasemia was defined as serum cholinesterase (ChE) activity >= 450 IU/L (>= 2.0 SD). We screened 11,648 consecutive outpatients between 2005 and 2011 at Toho University, Sakura Medical Center. In patients with severe hypercholinesterasemia, phenotyping of the C5 variant was conducted using polyacrylamide gel electrophoresis and alpha-naphthyl butyrate staining.', '157 subjects (1.4% of 11,648 outpatients screened) were diagnosed with severe hypercholinesterasemia (mean serum ChE activity 574 109 IU/L), and the frequency of the C5 variant was 45.2%. Subjects with the C5 variant had higher age, lower body mass index, milder dyslipidemia and liver dysfunction, and lower rates of hypertension and CAD compared with subjects without the C5 variant. Multivariate logistic regression model demonstrated that the presence of C5 variant independently lowered the risk of CAD, with odds ratio 0.071 (95% confidence interval (CI) 0.007 - 0.763, p = 0.029).\Question: Is c5 variant associated with decreased risk of coronary artery disease in outpatients with severe hypercholinesterasemia?
Example Output: The prevalence of the C5 variant was relatively high, and the C5 variant is associated with decreased risk of CAD in outpatients with severe hypercholinesterasemia.

Example Input: Context: To conduct clinical and genetic studies in a European family with autosomal dominant Stargardt-like macular dystrophy (adSTGD-like MD) and to investigate the functional consequences of a novel ELOVL4 mutation.', 'Ophthalmic examination and mutation screening by direct sequencing of the ELOVL4 gene was performed in two affected individuals. Wild-type and mutant ELOVL4 genes were expressed as enhanced green fluorescent protein (EGFP) fusion proteins in transient transfection in NIH-3T3 and HEK293 cells. To determine the subcellular localization of ELOVL4, an endoplasmic-reticulum (ER)-specific marker for pDsRed2-ER was cotransfected with ELOVL4 constructs. Transfected cells were viewed by confocal microscopy. Western blot analysis was performed to assess protein expression using an anti-GFP antibody.', 'Affected patients exhibited macular atrophy with surrounding flecks characteristic of adSTGD-like MD. A novel ELOVL4 p.Tyr270X mutation was detected in affected individuals. In cell-transfection studies, wild-type ELOVL4 localized preferentially to the ER. In contrast, the mutant protein appeared to be mislocalized within transfected cells.\Question: Does a novel mutation in the ELOVL4 gene cause autosomal dominant Stargardt-like macular dystrophy?
Example Output:
In a European family with adSTGD-like MD, a novel ELOVL4 mutation was found to underlie the disorder. Transfection studies indicated that, unlike wild-type ELOVL4, the mutant protein does not localize to the ER but rather appears to be sequestered elsewhere in an aggregated pattern in the cytoplasm. Further analysis of the function of normal and mutant ELOVL4 will provide insight into the mechanism of macular degeneration.
