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 present study aimed to identify the relationship between glycemic variability (GV) and the 10-y risk of cardiovascular disease (CVD) in type 2 diabetes mellitus (T2DM) patients with good glycemic control.', 'Two-hundred forty consecutive T2DM patients (HbA1c7.0%) without CVD were included to calculate the 10-y CVD risk by Framingham risk score (FRS), and divided into 3 groups: low-risk group (FRS10%), intermediate-risk group (>10%, 20%) and high-risk group (>20%). Inter-group differences of GV were determined by comparing the SD of blood glucose (SDBG), mean amplitudes of glycemic excursion (MAGE), and mean of daily differences (MODD) gathered from 72-h continuous glucose monitoring system.', 'The levels of SDBG and MAGE significantly increased along with the raises of 10-y CVD risk of T2DM patients (p<0.01). FRS was positively correlated with age, systolic blood pressure, SDBG and MAGE (r=0.717, 0.525, 0.509 and 0.485 respectively, p<0.01), while negatively correlated with the level of HDL-C (r=-0.348, p<0.01). Furthermore, multivariate logistic regression analysis confirmed that increased MAGE [OR: 1.623(1.198-2.316), p<0.001] and patients with high urine albumin excretion rates [OR: 1.743(1.247-2.793), p<0.001] were independent predictors for high 10-y CVD risk.\Question: Is glycemic variability evaluated by continuous glucose monitoring system associated with the 10-y cardiovascular risk of diabetic patients with well-controlled HbA1c?
answer:
GV predicts independently the 10-y CVD risk of T2DM patients with well-controlled HbA1c.

question:
Context: Intermittent hypoxia (IH)-induced activation of pro-inflammatory pathways is a major contributing factor to the cardiovascular pathophysiology associated with obstructive sleep apnea (OSA). Obesity is commonly associated with OSA although it remains unknown whether adipose tissue is a major source of inflammatory mediators in response to IH. The aim of this study was to test the hypothesis that IH leads to augmented inflammatory responses in human adipocytes when compared to cells of non-adipocyte lineages.', 'Human primary subcutaneous and visceral adipocytes, human primary microvascular pulmonary endothelial cells (HUMEC-L) and human primary small airway epithelial cells (SAEC) were exposed to 0, 6 or 12 cycles of IH or stimulated with tumor necrosis factor (TNF)-. IH led to a robust increase in NF-B DNA-binding activity in adipocytes compared with normoxic controls regardless of whether the source of adipocytes was visceral or subcutaneous. Notably, the NF-B response of adipocytes to both IH and TNF- was significantly greater than that in HUMEC-L and SAEC. Western blotting confirmed enhanced nuclear translocation of p65 in adipocytes in response to IH, accompanied by phosphorylation of I-B. Parallel to p65 activation, we observed a significant increase in secretion of the adipokines interleukin (IL)-8, IL-6 and TNF- with IH in adipocytes accompanied by significant upregulation of mRNA expression. PCR-array suggested profound influence of IH on pro-inflammatory gene expression in adipocytes.\Question: Are human adipocytes highly sensitive to intermittent hypoxia induced NF-kappaB activity and subsequent inflammatory gene expression?
answer:
Human adipocytes demonstrate strong sensitivity to inflammatory gene expression in response to acute IH and hence, adipose tissue may be a key source of inflammatory mediators in OSA.

question:
Context: Colorectal cancer screening beginning at age 50 is recommended for all Americans considered at average risk for the development of colorectal cancer regardless of gender or race/ethnicity. We determined the influence of gender and race/ethnicity on the cost-effectiveness of recommended colorectal cancer screening regimens.', 'We determined age-specific colorectal cancer incidence rates; the proportion of left-sided cancers; and the proportion of localized cancers in Asian, black, Latino and white men and women using the California Cancer Registry. We incorporated these data and available data for life expectancy and colorectal cancer survival to model the cost-effectiveness of two 35-year colorectal cancer-screening interventions.', 'Age-specific colorectal cancer incidence rates were highest in black men and lowest in Latino women. Screening beginning at age 50 was most cost-effective in black men and least cost-effective in Latino women (measured as dollars spent per year of life saved) using annual fecal occult blood testing combined with flexible sigmoidoscopy every five years and using colonoscopy every 10 years. The cost-effectiveness of a 35-year screening program in black men beginning at age 45 was similar to the cost-effectiveness of screening white men and black women beginning at age 50 and more cost-effective than screening nonblack women as well as Asian and Latino men beginning at age 50.\Question: Do gender and race/ethnicity affect the cost-effectiveness of colorectal cancer screening?
answer:
Screening is most cost-effective in black men because of high age-specific colorectal cancer incidence rates. Initiation of colorectal cancer screening in this high-risk group prior to age 50 should be strongly considered.
