Given a passage with a context and an answer, 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.

Input: Consider Input: Context: No previous studies have investigated the psychiatric characteristics of patients with postherpetic neuralgia (PHN). Similarly, no studies have been performed on patients with different chronic somatic symptoms due to a defined medical disease to compare the characteristics of psychiatric morbidity associated with each etiology.', 'After completing the subscales of the Symptom Checklist 90-R, a psychiatrist administered the Diagnostic Interview Schedule to all subjects. The psychiatric comorbidity in 35 patients with pain due to PHN was compared with a control group of 34 patients with the nonpainful aversive symptom of vertigo due to a peripheral vestibular disorder that caused unilateral hypofunction.', 'PHN patients had significantly more symptoms of major depression and somatization disorder. No significant differences were found between groups for psychiatric diagnoses. Patients with PHN reported significantly less acutely distressing somatic symptoms.
Answer: These results suggest that the psychiatric symptoms of patients with PHN are distinct from nonspecific acute distress and may be related to the experience of suffering from chronic neuropathic pain. Patients with PHN may not meet criteria for a psychiatric diagnosis, but their psychiatric comorbidity places them at substantial risk for increased pain, suicidal ideation, sustained disability, and the numerous complications of excessive medical evaluation and treatment. Patients with PHN should be evaluated specifically for psychiatric symptoms to reduce potential negative consequences through appropriate treatment.

Output: Do psychiatric symptoms and distress differ between patients with postherpetic neuralgia and peripheral vestibular disease?


Input: Consider Input: Context: Formyl peptide receptor 1 (FPR1) as a regulator of innate inflammatory response has been implicated in tumor progression of gliomas. The purpose of the present study was to evaluate the prognostic significance and the ligand-receptor interaction of FPR1 in gastric cancer (GC).', 'FPR1 was immunohistochemically-analyzed in tissue sections originating from 116 GC patients. Reverse transcription-polymerase chain reaction (RT-PCR) was used for the assessment of interaction between FPR1 and the FPR1 ligand annexin A1 (AnxA1) in GC cells.', 'High FPR1 expression was significantly associated with stage IV disease, submucosal invasion, serosal invasion, and clinical outcome of GC. Multivariate analysis showed that high FPR1 expression was an independent risk factor of poor overall survival in GC patients. FPR1 expression increased significantly when AnxA1 overexpression was present in GC cells. A positive feedback regulation of FPR1 was involved in the AnxA1-FPR1 signal transduction.
Answer: FPR1 expression may be used as a novel indicator to predict outcome in GC patients after gastrectomy.

Output: Is formyl Peptide receptor 1 expression associated with tumor progression and survival in gastric cancer?


Input: Consider Input: Context: Excessive time between the first presentation of symptoms of pulmonary tuberculosis (PTB) and diagnosis contributes to ongoing transmission and increased risk of infection in the community, as well as to increased disease severity and higher mortality. People with type 2 diabetes mellitus (T2DM) have a higher risk of developing PTB. However, the effect of T2DM on delayed diagnosis of PTB is not fully understood. This study investigated the effects of hyperglycemia (diabetes and prediabetes) and other factors on PTB patient delay in a rural area of China.', 'In the present community-based investigation, PTB patients aged ≥16\u2009years newly diagnosed at county tuberculosis dispensaries were recruited consecutively between September 2011 and December 2013. Fasting blood glucose was determined in all subjects, and a structured questionnaire was used to collect basic information.', 'Of the 2280 patients, 605 (26.5\xa0%) had hyperglycemia. The median (interquartile range) time to seeking health care was 44 (59) days. Health care seeking was delayed in 1754 subjects, and hyperglycemia was independently associated with an increased probability (odds ratio 2.10; 95\xa0% confidence interval 1.49-2.97) of patient delay in subjects aged ≥30\u2009years. Other factors associated with patient delay were cough, night sweats, and lack of knowledge regarding typical tuberculosis symptoms. The onset of hemoptysis was negatively correlated with patient delay.
Answer: Patient delay appears to be a serious problem in this rural area with a high prevalence of tuberculosis. Hyperglycemia is independently associated with an increased probability of patient delay, which, in turn, may result in more serious clinical manifestations.


Output: Is hyperglycemia associated with increased risk of patient delay in pulmonary tuberculosis in rural areas?
