[EX Q]: Question: Are chronic obstructive pulmonary disease patients with psychiatric disorders at greater risk of exacerbations?
Answer: Patients with psychiatric disorders are at greater risk of exacerbations treated in an outpatient setting but not those treated in an inpatient setting. These outpatient-managed exacerbations account for a significant proportion of the healthcare burden for COPD, so interventions should target patients with psychiatric disorders to improve management of COPD.
[EX A]: yes

[EX Q]: Question: Are fragile histidine triad gene alterations essential for hepatocellular carcinoma development in South Korea?
Answer: Aberrant FHIT transcripts were more common in HCC tissues as compared to non-cancerous liver tissues. However, Fhit expression was lost or reduced in a minor fraction of HCC tissues, while it was strongly expressed in non-cancerous liver tissues. Therefore, our study suggests that FHIT plays a role in relatively few HCC cases in South Korea.
[EX A]: no

[EX Q]: Question: Does chronic periglandular inflammation on prostate needle biopsy increase the likelihood of cancer on subsequent biopsy?
Answer: Although inflammation on initial and subsequent biopsy does not predict prostate cancer in this cohort, we cannot dismiss its role in prostate cancer pathogenesis. Additional research is necessary to explore the relationship between prostate inflammation and prostate cancer development.
[EX A]:
no
