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.

Input: Consider Input: Context: Cognitive changes after ischemic stroke are often overlooked, particularly acutely and in patients with mild or transient deficits. We assessed patients with transient ischemic attack (TIA)/minor stroke with serial cognitive screening tests. We tested the hypothesis that mild acute deficits are transient and improve after TIA/minor stroke.', 'Patients with acute TIA/minor ischemic stroke, without a history of cognitive impairment, presenting with a National Institute of Health Stroke Scale score 3 were assessed <72 hours of onset. Patients were administered the Mini-Mental State Examination (MMSE) and the Montreal Cognitive Assessment (MoCA) at days 1, 7, 30, and 90. Cognitive impairment was defined as MoCA <26 and MMSE 26.', 'One hundred patients with a median (interquartile range) National Institute of Health Stroke Scale score of 1 (2) and median age of 68 (20) years were included. Baseline median MoCA score (26 [4]) was lower than the MMSE (29 [2]; P<0.0001). Cognitive impairment was detected in 54 of 100 patients (54%) with MoCA and 16 of 100 (16%; P=0.001) with MMSE. MoCA scores improved at day 7 (27 [5]), day 30 (28 [2]), and day 90 (28 [2]; P<0.0001). Resolution of cognitive deficits was because of resolution of recall deficits.\Question: Do serial montreal cognitive assessments demonstrate reversible cognitive impairment in patients with acute transient ischemic attack and minor stroke?

Output: Acute temporary cognitive impairment after TIA/minor stroke is common. The MoCA is sensitive to these changes, but the MMSE is not. Routine cognitive assessment after TIA/minor stroke may be warranted and relevant to return to activities even when other neurological deficits are not evident.

Input: Consider Input: Context: Microalbuminuria and impaired endothelium-dependent vasodilation are both predictors for cardiac events in patients with type 2 diabetes. The aim of the study was to evaluate whether microalbuminuria correlated with coronary endothelium-dependent vasodilation.', 'We evaluated 84 patients (47 men, mean age 50.5 +/- 5.9 years) with type 2 diabetes for 9.4 +/- 3.4 years, without angiographic coronary stenosis and without major cardiovascular risk factors or other confounding factors, for endothelium investigation. Quantitative coronary angiography was used to assess coronary artery response to cold pressor testing, used to assess endothelium-dependent vasodilation, and to isosorbide dinitrate (endothelium-independent vasodilation).', 'Endothelium-dependent vasodilation differed in the patients with and without microalbuminuria (changes in coronary artery diameter during cold pressor testing: -15.0 +/- 1.9% vs. -10.2 +/- 1.3%, respectively, P < 0.05) and correlated with urinary albumin excretion rate (r = -0.39, P = 0.003), diastolic blood pressure (r = 0.29, P < 0.01), and left ventricular mass index (r = -0.24, P < 0.05). Independent predictors for endothelium-dependent vasodilation were urinary albumin excretion rate (beta -0.04 [95% CI -0.07 to -0.01], P < 0.005) and left ventricular mass index (-0.26 [-0.49 to -0.05], P < 0.05). Endothelium-independent vasodilation was similar in both groups.\Question: Is impaired coronary endothelium-dependent vasodilation associated with microalbuminuria in patients with type 2 diabetes and angiographically normal coronary arteries?

Output: Type 2 diabetic patients with microalbuminuria have a more severely impaired coronary endothelium-dependent vasodilation than those with normoalbuminuria. These data suggest a common pathophysiological process for both coronary vasomotor abnormalities and microalbuminuria.

Input: Consider Input: Context: Up-regulated expression of syndecan-1, a member of the transmembranous proteoglycans that serves as a co-receptor for a wide pool of extracellular ligands, has been ascribed to the promotion of growth of various cancers including breast, ovarian, and endometrial cancers. Here, we have extended these observations to gain insight into correlation between the expression level of syndecan-1 and its tumor-promoting characteristics, particularly, cancer invasion, in endometrial cancer.', 'Human syndecan-1 was stably transfected into three human endometrial cancer cell lines, and its effects were examined with respect to cell survival/proliferation and invasion. In addition, the activation of underlying signaling components, including integrins, focal adhesion kinase (FAK), and nuclear factor kappaB (NF-kappaB) was examined. The activity of NF-kappaB as a transcription factor for matrix metalloproteinase (MMP)-9 was assessed.', 'The innate expression level of syndecan-1 was moderate to high in all endometrial cancer cell lines. Overexpression of syndecan-1 promoted tumor cell proliferation concomitant with the activation of NF-kappaB. Furthermore, overexpression of syndecan-1 markedly enhanced the cancer invasion accompanied by enhanced expression of integrin alphav/beta5 and enhanced phosphorylation of FAK. The transcriptional activation of MMP-9 by NF-kappaB was up-regulated in syndecan-1 overexpression.\Question: Does syndecan-1 enhance the endometrial cancer invasion by modulating matrix metalloproteinase-9 expression through nuclear factor kappaB?
Output: These findings provide evidence that supports that syndecan-1 may have a critical role in carcinogenic progression, particularly, contributing to the development of proliferative and invasive phenotype through NF-kappaB-mediated MMP-9 gene expression in endometrial cancer.
