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.

[Q]: 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?
[A]: 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.


[Q]: Context: Upregulator of cell proliferation 4 (URG4) has been implicated in the oncogenesis of certain cancers. However, the correlation between URG4 expression and clinicopathological significance in human cancer remains unclear. Therefore, this study investigated its expression and clinicopathological significance in cervical cancer patients.', 'URG4 expression was examined using quantitative PCR (qPCR) and western blotting in normal cervical epithelial cells, cervical cancer cells, and eight matched pairs of cervical cancer tissues and adjacent noncancerous tissues from the same patient. In addition, immunohistochemistry (IHC) was used to examine URG4 expression in paraffin-embedded tissues from 167 cervical cancer patients (FIGO stages Ib1-IIa2). Statistical analyses were performed to evaluate associations between URG4 expression and prognostic and diagnostic factors.', 'URG4 was significantly upregulated in the cervical cancer cell lines and tissues compared with the normal cells and adjacent noncancerous cervical tissues. IHC revealed high URG4 expression in 59 out of the 167 (35.13%) cervical cancer specimens. Its expression was significantly correlated with clinical stage (P < 0.0001), tumour size (P = 0.012), T classification (P = 0.023), lymph node metastasis (P = 0.001) and vaginal involvement (P = 0.002). Patients with high URG4 expression, particularly those who received concurrent chemotherapy and radiotherapy (P < 0.0001), showed a shorter overall survival (OS) and disease-free survival (DFS) compared to those with the low expression of this protein. Multivariate analysis revealed that URG4 expression is an independent prognostic factor for cervical cancer patients.\Question: Is uRG4 overexpression correlated with cervical cancer progression and poor prognosis in patients with early-stage cervical cancer?
[A]: Our results demonstrated that elevated URG4 protein expression is associated with a poor outcome in patients with early-stage cervical cancer. URG4 may be a novel prognostic marker and therapeutic target for the treatment of cervical cancer.


[Q]: Context: The putative role of sulfur amino acids such as homocysteine (tHcy) as cardiovascular risk factors is controversial in chronic kidney disease (CKD). Although, S-adenosylhomocysteine (SAH) levels have been linked to CVD in non-renal populations, such relationship has not been evaluated in CKD.', 'Serum concentrations of S-adenosylmethionine (SAM), SAH and total homocysteine (tHcy) were determined by HPLC in 124 CKD stage 5 patients (GFR range 1-11 m/min) and 47 control subjects, and related to renal function, presence of CVD, inflammation and protein-energy wasting (PEW).', 'The levels of SAM and SAH were higher in CKD patients than in controls. Both SAM (rho=-0.19; P<0.05) and SAH (rho=-0.37, P<0.001) were inversely related to GFR. The concentrations of SAH were significantly higher (P<0.001) in patients with CVD than in non-CVD patients, (683 (201-3057) vs 485 (259-2620) nmol/L; median (range)) as opposed to tHcy levels, which were lower in CVD patients. While SAH was not associated with the presence of inflammation or PEW, it was a significant contributor (OR; 4.9 (CI 1.8-12.8), P<0.001) to CVD in a multinomial logistic regression model (pseudo r(2)=0.31).\Question: Are elevated serum levels of S-adenosylhomocysteine , but not homocysteine , associated with cardiovascular disease in stage 5 chronic kidney disease patients?
[A]:
Concentrations of serum SAH and SAM in CKD stage 5 patients are associated with renal function, but not with inflammation or PEW. Among the investigated sulfur amino acids, only SAH was independently associated with the presence of clinical signs of CVD. These findings suggest that while tHcy might be influenced by a number of confounding uremic factors, SAH levels may better reflect the putative increased cardiovascular risk of sulfur amino acid alterations in CKD patients.
