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.

Question: Context: The human RECQ DNA helicase family is involved in genomic stability. Gene mutations of RECQL2, RECQL3, and RECQL4 are associated with genetic disorders and induce early aging and carcinogenesis. Although previous studies have reported that the level of RECQL1 expression is correlated with the prognosis of some of malignancies, the function of RECQL1 is not yet clarified. The present study aimed to examine the relationship between prognosis and the level of RECQL1 expression in epithelial ovarian cancer (EOC), and to identify the role of RECQL1 in EOC cells.', 'The level of RECQL1 expression was determined immunohistochemically in 111 patients with EOC who received initial treatment at Hirosaki University hospital between 2006 and 2011. Effects of RECQL1 on cell growth or apoptosis were examined in vitro using wild-type and OVCAR-3 cells (RECQL1(+) cells) and similar cells transfected with RECQL1 siRNA transfected (RECQL1(-) cells).', 'The level of RECQL1 expression was not related to histological type, clinical stage, or retroperitoneal lymph node metastasis, but the expression level was significantly higher (P\u2009=\u20090.002) in patients with recurrence than those without recurrence, and progression-free survival and complete response rate to chemotherapy were also improved in patients with RECQL1-low expression (n = 39) stage III/IV EOC (P = 0.02 and P <0.05 vs RECQL1-high expression patients (n = ), respectively). A cell proliferation and colony formation assays revealed significantly less growth of RECQL1(-) cells compared to RECQL1(+) cells. A flow cytometry using annexin V -FITC and propidium iodide (PI) staining revealed a significant increase in apoptotic RECQL1(-) cells. Cell cycle analysis showed a significantly greater distribution in subG1 phase indicating apoptotic cells in RECQL1(-) cells than in RECQL1(+) cells.\Question: Is the level of RECQL1 expression a prognostic factor for epithelial ovarian cancer?

Answer: These results suggest that RECQL1 is a prognostic factor for EOC and that RECQL1 contributes to potential malignancy by inhibiting apoptosis.


Question: 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?

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


Question: Context: Oral mucositis (OM) is a relevant adverse effect of anticancer therapy involving ionizing radiation (IR) and doxorubicin (Doxo). Because DNA damage of keratinocytes is causative for the pathogenesis of OM, we aim to identify pharmacological measures for geno- and cytoprotection of keratinocytes.', 'We investigated the influence of the lipid-lowering drug lovastatin on cell death, proliferation and DNA damage response (DDR) mechanisms of human keratinocytes following treatment with IR and Doxo.', 'Lovastatin protected keratinocytes from the cytotoxic and genotoxic effects of IR and Doxo as shown by a diminished induction of apoptosis as well as a reduced formation and slightly improved repair of DNA damage following Doxo and IR treatment, respectively. Lovastatin selectively blocked the activation of Chk1 and ATR kinases following treatment with IR, Doxo and the ribonucleotide reductase inhibitor hydroxyurea, indicating that the statin antagonizes ATR/Chk1-regulated replicative stress responses. Part of the cytoprotective activity of lovastatin seems to rest on a delayed entry of lovastatin treated cells into S-phase. Yet, because the statin also protected non-proliferating keratinocytes from IR- and Doxo-induced cytotoxicity, cell cycle independent protective mechanisms are involved, too.\Question: Does lovastatin protect keratinocytes from DNA damage-related pro-apoptotic stress responses stimulated by anticancer therapeutics?

Answer:
Lovastatin attenuates pro-toxic DNA damage-related responses of keratinocytes stimulated by OM-inducing anticancer therapeutics. The data encourage forthcoming in vivo and clinical studies addressing the usefulness of statins in the prevention of OM.
