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.

Q: Context: To assess the ability of an adult risk screening questionnaire (RSQ), previously shown to predict attendance at hospital emergency departments, to identify impaired quality of life in adult patients with asthma in general practice.', 'Baseline data from an RCT of asthma clinics in general practice, using the St. George Respiratory Questionnaire (SGRQ) to measure quality of life.', 'Twelve general practices in Adelaide, Australia.', 'A total of 184 adult asthmatics were recruited, with a mean (standard deviation) age of 50.3 years (16.6 years). Age, gender, weight, number of comorbidities, smoking status, FEV1 and percent predicted FEV1 (pre-and post-bronchodilator), peak flow (pre and post), and RSQ were independently related to SGRQ scores. After adjusting for potential confounders, an RSQ score predictive of hospital attendance was also associated with an average increase (worsening) in SGRQ total score of 11.9 (95% CI: 7.6, 16.3), an average increase in activity score of 9.0 (2.5, 15.5), symptom score of 14.8 (8.6, 21.0), and impact score of 13.1 (8.6, 17.6). These represent clinically significant differences.\Question: Does hospital attendance prediction tool also identify impaired quality of life in adults with asthma in general practice?

A: An RSQ score predictive of hospital attendance should alert the general practitioner to explore and address symptom, activity, and impact domains associated with impaired quality of life in adult asthma.

Q: Context: Diabetes mellitus (DM) is a major risk factor for periodontal disease and affects various cellular functions. Periodontal ligament stem cells (PDLSCs) play an important role in periodontal tissue regeneration; however, the effect of hyperglycemia on PDLSCs is unclear. The aim of this study is to investigate whether hyperglycemia affects periodontal tissue regeneration, using human PDLSCs and high-glucose medium as a model of DM.', 'PDLSCs were obtained from healthy adult human mandibular third molars. Cell proliferation, osteoblastic differentiation, and proinflammatory cytokine expression were investigated by culturing PDLSCs in media supplemented with four different glucose concentrations representative of control patients (5.5 mM), patients with postprandial or controlled DM (8.0 mM), and patients with uncontrolled DM (12.0 and 24.0 mM). The molecular effects of hyperglycemia on PDLSC physiology were examined with a focus on the nuclear factor (NF)-(κB signaling pathway. The involvement of NF-κB was investigated with a specific NF-κB inhibitor in PDLSCs under hyperglycemic conditions.', 'High glucose levels inhibited PDLSC proliferation and differentiation into osteoblasts but induced NF-κB activation and subsequent interleukin (IL)-6 and IL-8 expression. Treatment with an NF-κB inhibitor rescued the defects in cell proliferation and osteoblastic differentiation and inhibited the IL-6 expression caused by the high-glucose environment.\Question: Do high Glucose Concentrations Suppress the Proliferation of Human Periodontal Ligament Stem Cells and Their Differentiation Into Osteoblasts?

A: The results of this study demonstrate that hyperglycemia inhibits human PDLSC proliferation and osteoblastic differentiation.

Q: Context: To bring further understanding to the relationship between hormonal therapy (HT) and breast arterial calcification (BAC).', 'Of women arriving for breast cancer screening mammography, 1995 consented to complete a survey and have their mammograms analyzed for the presence of BAC. The survey assessed HT use and major risk factors for CAD.', 'Of the 1919 women with complete data, there were 268 with BAC (14%). When categorized into three age groups, BAC was present in 40.7% of the women > or =65, 10.9% of those 55-64 and 3.0% of those <55. The > or =65 year-old group showed a nearly 50%-point lower prevalence of BAC among HT users compared with women who were not on HT (25.8% versus 74.2%, respectively, p=0.006). With age included as a continuous variable, past use of HT was significantly associated with a lower prevalence of BAC (p<0.03), while the presence of diabetes or a history of stroke were significantly associated with a higher prevalence of BAC (p<0.002).\Question: Is hormonal therapy associated with a lower prevalence of breast arterial calcification on mammography?

A:
Well-established cardiovascular risk factors (diabetes, stroke, and age) appear to be associated with a significantly higher incidence of BAC, while HT during the menopausal years appears to be associated with a significantly lower prevalence of BAC.
