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.

[Q]: 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.

[Q]: We designed an assessment and education program which was delivered to patients prior to first outpatient appointment for bariatric surgery. We hypothesised that this program would streamline care and would lead to improved weight loss following bariatric surgery.', 'The program incorporates a structured general practitioners (GP) review, a patient information evening and an on-line learning package. It was introduced in September 2012. Patient flow through the program was recorded. Outcomes of the new program were compared with contemporaneously treated patients who did not undertake the pre-hospital program.', 'All 636 patients on the waiting list for first appointment at the Alfred Health bariatric surgery clinic were invited to participate. There were 400 patients ultimately removed from the waiting list for first appointment. Of the remaining 236 patients, 229 consented to participate in the new program. The mean BMI was 47.89.2. The fail to attend first appointment rate dropped from 12 to 2.1%. At 12months post-bariatric surgery, patients who undertook the new program (n=82) had a mean excess weight loss (EWL) of 41.120.3% where as those treated on the standard pathway (n=61) had a mean EWL 3218.0% (p=0.012).

[Q]: the use of antihypertensive medication in older people in order to prevent cardiovascular events is well established. The use of such agents has been encouraged by incentive schemes in the United Kingdom including the Quality and Outcomes Framework. In addition, many guidelines recommend good blood pressure (BP) control in the elderly. However, in older people antihypertensives can cause adverse effects related to hypotension.', 'the aim of this study was to assess the prevalence of lowBP and impact on outcomes, particularly in the presence of antihypertensive treatment, in a primary care population of older people.', 'a retrospective observational cohort study in people over the age of 70 years registered with primary care providers in Kent.', 'a total of 11,167 patients over 70 years old were analysed, 6,373 female (57%). Systolic blood pressure (SBP) was below 120 mmHg in 1,297 people (844 on antihypertensives), below 110 mmHg in 474 (313 on antihypertensives) and below 100 mmHg in 128 (89 on antihypertensives). Hypotension was independently associated with mortality, acute kidney injury and hospital admission.
