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 study the pulmonary effects of aspirating a mixture of sucralfate in water and sucralfate in hydrochloric acid in an animal model of aspiration pneumonia.', 'Prospective, randomized, controlled study with repeated measures.', 'University research laboratory.', 'Thirty-two in situ, isolated, blood perfused porcine lung preparations.', 'Five control preparations received no aspiration. Twenty-seven preparations received a standard aspiration of 1.5 mL/kg body of a) distilled water (n = 5), b) sucralfate in distilled water (n = 8), c) 1/10 normal hydrochloric acid (n = 6), and d) mixture of sucralfate in distilled water and hydrochloric acid (n = 8).', 'The pH measurements were made of all aspirates. Lung weight, airway pressures, and pulmonary artery pressures were continuously monitored before and for 4 hrs after aspiration. Lung wet/dry weight ratio was measured at the completion of the study.', 'The pH of sucralfate mixed with distilled water was 4.9, pH of 1/10 normal hydrochloric acid was 1.0, and pH of equal volumes of a sucralfate-water suspension mixed with hydrochloric acid was 1.5. Airway pressures and pulmonary arterial pressures increased in all aspirate groups over time compared with those values of control lungs. Control lungs gained 18 +/- 3 (SEM) g over 4 hrs and the wet/dry ratio was 4.951 +/- 0.310. Lungs aspirating distilled water gained 147 +/- 49 g and the wet/dry ratio was 5.198 +/- 0.120. Lungs aspirating sucralfate and distilled water increased their weight by 109 +/- 30 g and the wet/dry ratio was 5.380 +/- 0.076. Lungs aspirating a suspension of sucralfate and water and hydrochloric acid were similar to lungs aspirating hydrochloric acid alone with weight increases of 265 +/- 30 g and 346 +/- 81 g, and the wet/dry ratio of 7.011 +/- 0.273 and 7.230 +/- 0.390, respectively.\Question: Does sucralfate reduce the risk of acid aspiration pneumonitis?

A: Sucralfate has minimal acid buffering effect. Aspiration of sucralfate mixed with distilled water causes lung edema similar to aspiration of water alone. Aspiration of a sucralfate-water suspension mixed with hydrochloric acid causes severe lung edema. These results suggest that patients given sucralfate prophylaxis for stress ulceration are at risk for acid aspiration.

Q: Context: We aimed to evaluate the relationship between estimated glomerular filtration rate (eGFR) and QT dispersion (QTd) in patients with coronary artery disease (CAD).', 'Sixty patients(mean age 62.72 ± 12.48 years) included 46 male, (mean age 60.89 ± 12.70 years)and 14 female (mean age 68.71± 9.86 years) were enrolled in this study. Patients were divided into 2 groups according to their eGFR using the 6 variable MDRD equation. Group 1 consisted of patients with estimated eGFR<60 ml/min/1.73m(2) and Group 2 consisted of patients witheGFR ≥ 60 ml/min/1.73m(2).', 'Baseline patient characteristics were homogeneous in both groups except for age, gender and smoking.Also, the extent of CAD was similar in both groups (p > 0.05) QTd values were found higher in group 1 than those of group 2 (57.23 ± 40.65 ms vs. 31.23 ± 14.47 ms, p = 0.002). After adjustment for age, gender and smoking using one-way ANCOVA test, statistically significant difference in QTd still existedbetween the groups (p=0.038).\Question: Does qT dispersion increase with low glomerular filtration rate in patients with coronary artery disease?

A: QTd tends to be higher in patients with poor renal function independent of severity of angiographical CAD. QTd may be a potentially useful non-invasive test in the management of patients with poor renal function, especially those with CAD.

Q: Context: The study of inter-individual interactions (often termed spatial-temporal interactions, or dynamic interactions) from remote tracking data has focused primarily on identifying the presence of such interactions. New datasets and methods offer opportunity to answer more nuanced questions, such as where on the landscape interactions occur. In this paper, we provide a new approach for mapping areas of spatial-temporal overlap in wildlife from remote tracking data. The method, termed the joint potential path area (jPPA) builds from the time-geographic movement model, originally proposed for studying human movement patterns.', 'The jPPA approach can be used to delineate sub-areas of the home range where inter-individual interaction was possible. Maps of jPPA regions can be integrated with existing geographic data to explore landscape conditions and habitat associated with spatial temporal-interactions in wildlife. We apply the jPPA approach to simulated biased correlated random walks to demonstrate the method under known conditions. The jPPA method is then applied to three dyads, consisting of fine resolution (15 minute sampling interval) GPS tracking data of white-tailed deer (Odocoileus virginianus) collected in Oklahoma, USA. Our results demonstrate the ability of the jPPA to identify and map jPPA sub-areas of the home range. We show how jPPA maps can be used to identify habitat differences (using percent tree canopy cover as a habitat indicator) between areas of spatial-temporal overlap and the overall home range in each of the three deer dyads.\Question: Do mapping areas of spatial-temporal overlap from wildlife tracking data?

A:
The value of the jPPA approach within current wildlife habitat analysis workflows is highlighted along with its simple and straightforward implementation and interpretation. Given the current emphasis on remote tracking in wildlife movement and habitat research, new approaches capable of leveraging both the spatial and temporal information content contained within these data are warranted. We make code (in the statistical software R) for implementing the jPPA approach openly available for other researchers.
