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

[EX Q]: Context: To determine whether testosterone levels change as women with the polycystic ovary syndrome (PCOS) grow older.', 'A follow-up cross-sectional study of a cohort of women with PCOS identified up to 20-25 years ago.', 'Women with PCOS were recruited primarily from practice records between 1970 and 1990. Voter registration tapes and household directories were used to identify age-, race-, and neighborhood-matched controls.', 'Eighty-four women with PCOS, 20-57 years of age, and 37 age-matched controls participating in a study of the risk for cardiovascular disease in women with PCOS.', 'Clinical data were collected by questionnaire and fasting blood samples were obtained randomly throughout the menstrual cycle.', 'Total and non-SHBG-bound testosterone levels.', 'Total and non-SHBG-bound testosterone levels were similar in women with PCOS who were 20-42 years of age but were reduced by approximately 50% among women 42-47 years of age and remained stable in women older than 47 years of age. Testosterone levels were increased in younger and older women with PCOS compared with controls but were similar to controls in women 42-47 years of age.\Question: Do serum testosterone levels decrease in middle age in women with the polycystic ovary syndrome?
[EX A]: Hyperandrogenism partly resolves before menopause in women with PCOS. This change may explain the tendency of women with PCOS to cycle regularly as they grow older. Testosterone levels remain elevated in older women with PCOS, however, and may contribute to their increased risk for cardiovascular disease, endometrial cancer, and other diseases.

[EX Q]: Context: High fibroblast growth factor-23 (FGF-23) levels are associated with mortality and cardiovascular events in patients with chronic kidney disease. The aim of this cross-sectional study was to investigate the relationship between plasma FGF-23 levels and coronary artery calcification and carotid artery intima-media thickness (CA-IMT) in hemodialysis (HD) patients.', 'In this cross-sectional study, plasma intact FGF-23 levels were measured in 229 patients who underwent coronary artery calcification scores (CACs) determined by multi-slice computerized tomography and CA-IMT assessed by using high-resolution color Doppler ultrasonography.', 'Median FGF-23 was 53.5 pg/ml (IQR 30.8-249.5). Median CACs was 98 (IQR 0-531), and the frequency of patients with severe calcification (CACs > 400) was 28.8%; 27.5% of cases had no calcification. Mean CA-IMT was 0.78 ± 0.20 mm, and the presence of carotid plaques was 51% with a mean length 2.1 mm. FGF-23 level was positively correlated with serum calcium (r = 0.337, p < 0.001), phosphate (r = 0.397, p < 0.001) and CACs (r = 0.218, p = 0.001). Neither CA-IMT nor the presence of carotid artery plaques correlated with FGF-23 levels. In adjusted ordinal regression analysis, FGF-23 level was an independent predictor for severe CACs together with age, gender, presence of diabetes, time on dialysis and CA-IMT (model r(2) = 0.44, p < 0.001). As a novel finding, the mean CACs was markedly higher in patients with FGF-23 level above median regardless of phosphate levels (p = 0.03).\Question: Are fGF-23 levels associated with vascular calcification , but not with atherosclerosis , in hemodialysis patients?
[EX A]:
In HD patients, plasma FGF-23 level is superior to phosphate in the prediction of coronary artery calcification. However, FGF-23 is not associated with carotid artery atherosclerosis in HD patients.
