TASK DEFINITION: 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.
PROBLEM: Context: Physical activity is beneficial for cancer survivors, but exercise participation is low in this population. It is therefore important to understand the psychological factors underlying exercise uptake so that more effective interventions can be developed. Social-cognitive theory constructs such as outcome expectancies predict exercise behavior, but self-report measures have several limitations. We examined the associations between implicit (automatic) cognitions and exercise behavior and self-efficacy in endometrial cancer survivors.', 'This was a longitudinal study to examine predictors of exercise behavior in female endometrial cancer survivors who all received an exercise intervention. Participants (N = 100, mean age of 57.0) completed questionnaires to assess self-report exercise-related measures (outcome expectancy and attitudes about and identification with exercise) and reaction time (RT) tasks to assess implicit exercise cognitions (expectancy accessibility, implicit attitudes about exercise, and implicit self-identification with exercise) at baseline and at 2, 4, and 6 months at follow-up. Exercise behavior was measured using accelerometers and self-report. Data were analyzed using linear mixed models.', 'Expectancy accessibility was associated with exercise duration independent of the corresponding self-report measure. Exercise implicit attitudes and self-identification were prospectively associated with exercise self-efficacy only after adjustment for the corresponding self-report measures and baseline self-efficacy. Self-report measures were also associated with study outcomes.\Question: Are self-reported and automatic cognitions associated with exercise behavior in cancer survivors?

SOLUTION: Both self-reported cognitions and implicit cognitions may be useful to identify individuals at risk of failing to exercise. Individuals so identified might be provided with a different or more intensive intervention. The data also suggest cognitive targets for intervention. (PsycINFO Database Record

PROBLEM: Context: Primary pneumonic plague is a rare but often fatal form of Yersinia pestis infection that results from direct inhalation of bacteria and is potentially transmissible from person to person. We describe a case of primary pneumonic plague in a wildlife biologist who was found deceased in his residence 1 week after conducting a necropsy on a mountain lion.', "To determine cause of death, a postmortem examination was conducted, and friends and colleagues were interviewed. Physical evidence was reviewed, including specimens from the mountain lion and the biologist's medical chart, camera, and computer. Human and animal tissues were submitted for testing. Persons in close contact (within 2 meters) to the biologist after he had developed symptoms were identified and offered chemoprophylaxis.", 'The biologist conducted the necropsy in his garage without the use of personal protective equipment. Three days later, he developed fever and hemoptysis and died approximately 6 days after exposure. Gross examination showed consolidation and hemorrhagic fluid in the lungs; no buboes were noted. Plague was diagnosed presumptively by polymerase chain reaction and confirmed by culture. Tissues from the mountain lion tested positive for Y. pestis, and isolates from the biologist and mountain lion were indistinguishable by pulsed-field gel electrophoresis. Among 49 contacts who received chemoprophylaxis, none developed symptoms consistent with plague.\Question: Do primary pneumonic plague contracted from a mountain lion carcass?

SOLUTION: The biologist likely acquired pneumonic plague through inhalation of aerosols generated during postmortem examination of an infected mountain lion. Enhanced awareness of zoonotic diseases and appropriate use of personal protective equipment are needed for biologists and others who handle wildlife.

PROBLEM: Context: The aim of this study was to investigate the smoking status of lung cancer patients and to confirm the risk of smoking for patients undergoing lung cancer surgery.', 'We conducted a retrospective study of patients undergoing lung cancer surgery. Between May 2004 and March 2013, 716 patients underwent lung cancer surgery at our institution. Based on smoking status, the patients were classified into 3 groups: nonsmoker, past smoker, and current smoker. Based on exclusion criteria, a final total of 670 patients were investigated for the association between smoking status and postoperative complications. In addition, we explored the effect of smoking on survival after surgery.', 'There were 254 non-smokers, 246 past smokers, and 170 current smokers. The percent of female patients, adenocarcinoma, and stage IA cancer was highest in the nonsmokers. Respiratory function was significantly impaired in past and current smokers. Respiratory and cardiac complications were found less frequently in non-smokers (11.4%) followed by 17.1% of past smokers and 21.2% of current smokers (p = 0.0226). Univariate analysis showed that smoking was a significantly poor prognostic factor for overall survival. The 5-year survival rates for non-smokers, past, and current smokers were 81.4, 65.4, and 68.8%, respectively (p = 0.0003).\Question: Is smoking a perioperative risk factor and prognostic factor for lung cancer surgery?

SOLUTION:
Smokers with lung cancer tended to have advanced lung cancer, impaired pulmonary function, and high morbidity after lung cancer surgery. Although multivariate analysis did not show that smoking was associated with poor outcome, non-smokers had significantly better overall survival, even for patients with stage IA lung cancers.
