Given a passage, construct a question on the basis of the information present in the passage. Construct the question in such a way that (i) it is unambiguous, (ii) it is answerable from the passage, (iii) its answer is unique (iv) it answer uses text phrases from the passage. Avoid creating questions that (i) can't be answered correctly without actually understanding the passage and (ii) uses the same words or phrases given in the passage.

Question: Patients with alcoholic liver disease (ALD) display inflammation of the subcutaneous adipose tissue (SAT) which correlates with liver lesions. We examined macrophage markers and polarization in the SAT of alcoholic patients and adipokine expression according to liver inflammation; we studied the consequences of alcohol withdrawal.', 'Forty-seven patients with ALD were prospectively included. SAT and blood samples were collected at inclusion and after 1week of alcohol withdrawal. Pro-inflammatory cytokines/chemokines, inflammasome components and products, adipokine expression levels, macrophage markers and polarization in liver and SAT samples were assessed by RT-PCR arrays.', 'mRNA expression level of chemokines (IL8, semaphorin 7A) correlated with hepatic steatosis in both liver and SAT. Liver expression of inflammasome components (IL1, IL18, caspase-1) and SAT IL6 and CCL2 correlated with liver damage. In patients with mild ALD, 1week of alcohol withdrawal was sufficient to decrease expression level of total macrophage markers in the adipose tissue, to orient adipose tissue macrophages (ATM) towards an anti-inflammatory M2 phenotype and to decrease the mRNA expression of cytokines/chemokines (IL18, CCL2, osteopontin, semaphorin 7A). In patients with severe ALD, 1week of abstinence was also associated with an increase in CCL18 expression.

Answer: Does alcohol withdrawal alleviate adipose tissue inflammation in patients with alcoholic liver disease?

Question: Pituitary tumor-transforming gene (PTTG) is a multifunctional protein involved in several tumorigenic mechanisms, including angiogenesis. PTTG has been shown to promote angiogenesis, a key rate-limiting step in tumor progression, by up-regulation of fibroblast growth factor-2 and vascular endothelial growth factor.', 'To investigate whether PTTG regulates other angiogenic genes in thyroid cells, we performed angiogenesis-specific cDNA arrays after PTTG transfection. Two of the genes [inhibitor of DNA binding-3 (ID3) and thrombospondin-1 (TSP-1)] which showed differential expression in primary thyroid cells were validated in vitro and in vivo.', 'TSP-1 showed a 2.5-fold reduction and ID3 showed a 3.5-fold induction in expression in response to PTTG overexpression in vitro. Conversely, suppression of PTTG with small interfering RNA was associated with a 2-fold induction of TSP-1 and a 2.2-fold reduction in ID3 expression. When we examined TSP-1 and ID3 expression in 34 differentiated thyroid cancers, ID3 was significantly increased in tumors compared with normal thyroid tissue. Furthermore, ID3 expression was significantly higher in follicular thyroid tumors than in papillary tumors. Although mean TSP-1 expression was not altered in cancers compared with normal thyroids, we observed a significant independent association between TSP-1 expression and early tumor recurrence, with recurrent tumors demonstrating 4.2-fold lower TSP-1 expression than normal thyroid tissues.

Answer: Does pituitary tumor-transforming gene regulate multiple downstream angiogenic genes in thyroid cancer?

Question: Examine relationships between adult obesity, childhood overweight, and food insecurity.', 'Cross-sectional retrospective study.', 'Community settings in Hartford, Connecticut.', 'Convenience sample of 200 parents and their 212 children, aged 2-12.', 'Adult obesity (Body Mass Index [BMI] > 30), childhood overweight (BMI-for-age > 95(th) percentile), and household food security (U.S. Department of Agriculture module).', 'Chi-square tests between weight status and socioeconomic characteristics. Multinomial regression analyses to determine risk factors for adult obesity and childhood overweight.', 'Over half of parents (51%) were obese, and almost one-third of children (31.6%) were overweight. Over half of households were food insecure. Food insecure adults were significantly more likely to be obese as those who were food secure (Odds Ratio [OR]=2.45, p = .02). Being a girl and having an obese parent doubled the likelihood of children being overweight (OR=2.56, P = .01; OR=2.32, P = .03). Children with family incomes below 100% of poverty were half as likely to be overweight as those with higher incomes (OR=.47, P = .05). Food insecurity did not increase odds of childhood overweight.

Answer:
Are food insecurity and gender risk factors for obesity?
