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: The PlA1/A2 polymorphism of platelet glycoprotein IIIa (GPIIIa) has been implicated in the pathogenesis of type 2 diabetes. We studied this polymorphism in a homogenous, extensively phenotyped cohort using the candidate gene approach.', 'The PlA1/A2 polymorphism was determined in 1051 patients with type 2 diabetes and in 2247 individuals without type 2 diabetes.', 'In patients with type 2 diabetes, genotype frequencies were as follows: PlA1/A1 71.4%, PlA1/A2 26.0%, and PlA2/A2 2.7%. In individuals without type 2 diabetes, genotype frequencies were 71.6%, 25.7% and 2.8%, respectively. The PlA2 allele was not associated with fasting and postprandial glucose, glycated haemoglobin, insulin, proinsulin, C-peptide and calculated indices of insulin resistance or pancreatic beta cell function. The PlA2 allele was also not significantly associated with angiographic CHD (adjusted odds ratio [OR] 1.13; 95% CI, 0.93-1.39) or with a history of previous myocardial infarction (adjusted OR 1.09; 95% CI, 0.87-1.37).\Question: Is the PlA1/A2 polymorphism of platelet glycoprotein IIIa associated with the risk of type 2 diabetes . The Ludwigshafen Risk and Cardiovascular Health study?

A: The GPIIIa PlA1/A2 polymorphism is not associated with type 2 diabetes, glucose metabolism, angiographic CHD or myocardial infarction.

Q: Context: Mucus hypersecretion and neutrophil infiltration are important characteristics of airway inflammation. Epidermal growth factor receptor (EGFR) transactivation induces mucus and inflammatory cytokine secretion from airway epithelial cells. To elucidate the roles of EGFR in airway inflammation, the in vitro effects on mucin production and interleukin (IL) 8 secretion from cultured airway epithelial cells and the in vivo effects on mucus hypersecretion and neutrophil infiltration in rat nasal mucosa of the EGFR tyrosine kinase inhibitor AG1478 were examined.', 'The in vitro effects of AG1478 treatment of cultured NCI-H292 cells on lipopolysaccharide (LPS) induced or tumor necrosis factor (TNF) α induced MUC5AC mucin and IL-8 secretion were evaluated. Hypertrophic and metaplastic changes of goblet cells, mucus production and neutrophil infiltration in rat nasal epithelium were induced by intranasal instillation of LPS in vivo, and the inhibitory effects of AG1478 by intraperitoneal injection or intranasal instillation were examined.', 'AG1478 (1-1000 nM) significantly inhibited both LPS-induced and TNF-α-induced secretion of MUC5AC and IL-8 from cultured NCI-H292 cells in a dose-dependent manner. The expression of MUC5AC and IL-8 messenger RNAs was also significantly inhibited. Intranasal instillation of AG1478 one hour after intranasal LPS instillation significantly inhibited LPS-induced goblet cell metaplasia, mucus production, and neutrophil infiltration in rat nasal epithelium, as did intraperitoneal injection of AG1478 one hour before LPS instillation.\Question: Does epidermal growth factor receptor inhibitor AG1478 inhibit mucus hypersecretion in airway epithelium?

A: These results indicated that EGFR transactivation plays an important role in mucin and IL-8 secretion from airway epithelial cells. Intranasal instillation of an EGFR tyrosine kinase inhibitor may be a new therapeutic approach for the treatment of upper airway inflammation.

Q: Context: Several studies have shown excess mortality among hip fracture patients compared with the normal population of the same age. Finnish guidelines for medical treatment of hip fracture patients recommend anti-osteoporosis medication and the daily concomitant use of prescribed calcium and vitamin D supplements. However, whether post-fracture use of calcium and vitamin D supplements is associated with survival in such patients has not been evaluated.', "To study the association between survival in hip fracture patients and patients' sex and age, pre-fracture vitamin D status, American Society of Anesthesiologists - Physical Status (ASA-PS) class, type of fracture and post-fracture use of prescribed calcium plus vitamin D and anti-osteoporotic medication.", "The study population was 221 hip fracture patients primarily treated in acute care for a new hip fracture in 2003-4 in two Finnish hospitals. After a median of 27.5 months from the fracture, a questionnaire was sent to all patients who were still alive at the time (n = 137). The patients were queried about their use of prescribed calcium plus vitamin D supplementation and of anti-osteoporotic drugs. The follow-up time for use of anti-osteoporotic medication and prescribed calcium and vitamin D was 19.5-36 months (median 27.5 months). Data on the use of prescribed calcium plus vitamin D supplementation and anti-osteoporotic drugs were checked against information on reimbursement of drug prescriptions held by the Finnish Social Insurance Institution. A total of 4 years' (48 months') survival data for all patients in the study population was also obtained, with the dates of patient deaths being checked against Official National and Regional population statistics. Patient survival was analysed using both the Bayesian multivariate analysis and the life table method.", 'In the multivariate analysis, the combination of variables that best explained post-fracture survival was as follows: age <80 years; ASA-PS class 1-2 (ASA-PS class 1 and 2 data were combined in calculations); post-fracture use of prescribed calcium plus vitamin D supplements concomitantly with anti-osteoporotic drugs; post-fracture use of prescribed calcium plus vitamin D supplements; post-fracture use of anti-osteoporotic drugs only; and type of fracture (femoral neck or subtrochanteric). This model correctly predicted 74% of cases. At 36 months, we observed a 36% reduction in deaths in females who used prescribed calcium plus vitamin D supplementation and a corresponding 43% reduction in males. Survival of females who used anti-osteoporotic drugs concomitantly was even greater (43% reduction in deaths) over the entire follow-up period. Excess mortality was highest in females and males who used neither anti-osteoporotic drugs nor prescribed calcium and vitamin D.\Question: Is post-fracture prescribed calcium and vitamin D supplements alone or , in females , with concomitant anti-osteoporotic drugs associated with lower mortality in elderly hip fracture patients : a prospective analysis?

A:
Our results indicate a potential relationship between reduced mortality and post-fracture use of prescribed calcium plus vitamin D supplementation and, in females, concomitant use of anti-osteoporotic drugs. However, further investigations are needed to understand the reason for the reduction in the risk of death. Population-based, randomized, placebo-controlled trials with total mortality as the main endpoint should be conducted to verify our results.
