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.

Context: To investigate whether the association between APOE-epsilon4 and memory decline is modified by baseline cognition and age in a population-based elderly sample.', 'The study sample consisted of 1,243 subjects, 62 to 85 years old, with a Mini-Mental State Examination (MMSE) score between 21 and 30 and known APOE phenotypes. Memory performance was measured with an abbreviated Auditory Verbal Learning Test (AVLT) at baseline and repeated after 3 years (n = 854). Memory decline was defined as a decrease of at least 1 SD from the mean change score on immediate recall (IR), delayed recall (DR), and retention, based on the AVLT.', 'Multivariate logistic regression analyses showed that APOE-epsilon4 is associated with memory decline in cognitively impaired subjects (MMSE score, 21 to 26) (OR for decline on IR adjusted for age, sex, education, and baseline recall score, 3.8; 95% CI, 1.4 to 10.0; adjusted OR for decline on DR, 2.9; 95% CI, 1.2 to 7.0; adjusted OR for decline on retention, 3.3; 95% CI, 1.1 to 10. 1), but not in cognitively normal subjects (MMSE score, 27 to 30) (adjusted OR for decline on IR, 1.1; 95% CI, 0.6 to 2.0; adjusted OR for decline on DR, 1.0; 95% CI, 0.6 to 1.8; adjusted OR for decline on retention, 1.5; 95% CI, 0.7 to 3.0). In particular, cognitively impaired epsilon4 carriers older than 75 years were at high risk of memory decline (adjusted OR for decline on IR, 4.5; 95% CI, 1.4 to 13.8; adjusted OR for decline on DR, 3.6; 95% CI, 1.2 to 10.8; adjusted OR for decline on retention, 6.6; 95% CI, 1.5 to 29.7).\Question: Is aPOE-epsilon4 associated with memory decline in cognitively impaired elderly?
APOE-epsilon4 was associated with memory decline in subjects with cognitive impairment, but not in normally functioning subjects. Contrary to AD studies, our study suggests that the risk of APOE-epsilon4 on memory decline does not decrease at higher ages.

Context: Familial hypercholesterolemia (FH) is a genetic disorder characterized by elevated levels of total cholesterol (TC) and low-density lipoprotein cholesterol (LDL-C). Guidelines recommend cholesterol-lowering medication from 8 to 10 years of age and dietary recommendations. Little is known about the diet of FH children and the effect of dietary counseling. The aim of the study was to describe the diet of FH children with respect to fat quality, and to investigate if dietary counseling improved lipid profile.', 'Fifty-four FH children (5-18 years) were included in the study and dietary intake was recorded with a pre-coded food diary for four days. Information about plasma lipid levels was obtained.', 'Median intake of total fat, monounsaturated fat, polyunsaturated fat (PUFA) and saturated fat (SFA) was 30.8, 10.4, 5.9 and 12.0E %, respectively. Among non-statin treated FH children, SFA intake was significantly correlated with TC, LDL-C and apolipoprotein (apo) B (rsp=0.55; p=0.004, rsp=0.46; p=0.02, and rsp=0.45; p=0.02, respectively), and PUFA/SFA ratio significantly inversely correlated with TC (rsp=-0.42; p=0.03). Compared to the first visit, non-statin and non-plant sterol treated FH children (n=10) had significantly reduced levels of TC (p<0.01), LDL-C (p=0.01), high-density lipoprotein cholesterol (p=0.02), apo B (p=0.05) and apo A-1 (p=0.02) levels at a later visit.\Question: Is dietary counseling associated with an improved lipid profile in children with familial hypercholesterolemia?
FH children had a higher intake of SFA than recommended and the SFA intake was positively correlated with plasma TC, LDL-C and apo B levels in FH children not using statins. Importantly, the plasma lipid profile was improved in FH children after dietary counseling where focus was on reducing intake of SFA and dietary cholesterol.

Context: Endoscopic ultrasound-guided fine needle aspiration (EUS-FNA) cytology is an effective tool to diagnose pancreatic ductal adenocarcinoma (PDA). Standard morphological criteria are usually reliable. When contaminating gastrointestinal (GI) epithelial cells are prevalent among neoplastic cells, these can be highlighted by carcinoembryonic antigen (CEA) staining. CD10 is a cell-surface metallopeptidase normally expressed by the GI epithelial apical border, whose expression is decreased or lost in PDA. We included CD10 in a panel, together with CEA, to discriminate the GI contaminant cells from PDA cells on cell blocks.', 'Eight cases of EUS-FNA of PDA, featuring both contaminating GI cells and neoplastic cells, whose corresponding cell blocks were available for immunostaining, were selected. CD10 and CEA were stained on cell blocks by standard methods.', 'CD10 strongly labelled only the GI cells, with a well-defined apical membrane signal; conversely, GI cells did not show CEA staining; benign duodenal cells were faintly labelled in only one case. Malignant cells were positive for CEA and negative for CD10, with the exception of one case with labelled neoplastic cells with weak diffuse cytoplasmic positivity. CD10 apical membrane staining was a feature only seen in benign GI cells.\Question: Is cD10 useful to identify gastrointestinal contamination in endoscopic ultrasound-guided fine needle aspiration ( EUS-FNA ) cytology from pancreatic ductal adenocarcinoma?
As a loss of CD10 is a consistent feature of PDA, this marker can be useful, together with CEA, to aid the cytopathologist to identify neoplastic cells in a background rich in GI contaminant cells.
