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: Slumped posture is a diagnostic feature of depression. While research shows upright posture improves self-esteem and mood in healthy samples, little research has investigated this in depressed samples. This study aimed to investigate whether changing posture could reduce negative affect and fatigue in people with mild to moderate depression undergoing a stressful task.', 'Sixty-one community participants who screened positive for mild to moderate depression were recruited into a study purportedly on the effects of physiotherapy tape on cognitive function. They were randomized to sit with usual posture or upright posture and physiotherapy tape was applied. Participants completed the Trier Social Stress Test speech task. Changes in affect and fatigue were assessed. The words spoken by the participants during their speeches were analysed.', 'At baseline, all participants had significantly more slumped posture than normative data. The postural manipulation significantly improved posture and increased high arousal positive affect and fatigue compared to usual posture. The upright group spoke significantly more words than the usual posture group, used fewer first person singular personal pronouns, but more sadness words. Upright shoulder angle was associated with lower negative affect and lower anxiety across both groups.\Question: Does upright posture improve affect and fatigue in people with depressive symptoms?
[A]: The experiment was only brief and a non-clinical sample was used.


[Q]: Context: Chronic pancreatitis (CP) and pancreatic cancer (PCa) are characterized by intrapancreatic neuropathic alterations, including increased neural density and hypertrophy, pancreatic neuritis and neural invasion (NI) by cancer cells in PCa. The aim of this study was to identify the influence of these neuropathic changes on the quality of pancreatic innervation, intrapancreatic glia, and visceral pain.', 'Pancreatic nerve fiber qualities were characterized by immunohistochemical visualization of various markers, including those for sympathetic (tyrosine hydroxylase, TH) and cholinergic innervation (choline acetyltransferase, ChAT), as well as the glial transcription factor, Sox10, and the neuroepithelial progenitor cell marker, Nestin, in normal pancreas (NP, n=16), CP (n=20), and PCa (n=20) patients. The neural immunoreactivity scores of these markers were correlated with the severity of intrapancreatic neuropathic changes and with abdominal pain sensation of patients.', 'Pancreatic sympathetic innervation was significantly reduced in CP and PCa, whereas parasympathetic innervation did not show major changes. Nestin neuro-immunoreactivity was stronger, and Sox10-immunoreactivity was weaker in CP and PCa than in NP. Pancreatic sympathetic and cholinergic innervation was noticeably decreased in patients with severe pancreatic neuritis, NI by cancer cells, or abdominal pain. Moreover, the neural immunoreactivity for Sox10 and Nestin also varied with intrapancreatic neuropathic alterations and abdominal pain.\Question: Does pancreatic neuropathy result in `` neural remodeling '' and altered pancreatic innervation in chronic pancreatitis and pancreatic cancer?
[A]: The quality of intrapancreatic nerve fibers and the activation state of intrapancreatic glia in CP and PCa are strikingly different from those in normal pancreas. This novel phenomenon of "neural remodeling" shows how pancreatic neuropathic pain and "visceral neuropathy" are associated with altered pancreatic innervation in CP and PCa.


[Q]: Context: It is unknown whether receiving treatment that is discordant with practice guidelines is associated with improved survival in patients with nasopharyngeal carcinoma. The objectives of this study were to characterise national treatment patterns, analyse whether treatment outside of practice guidelines is associated with overall survival, and identify variables associated with receiving guidelines-discordant care in the USA.', 'This was a retrospective cohort study of 1741 nasopharyngeal carcinoma patients in the National Cancer Data Base (2003-2006). Treatment regimens were compared with the 2004-2006 National Comprehensive Cancer Network guidelines. Statistical analyses included chi-square, Kaplan-Meier, multivariable logistic, and Cox regression.', 'Nearly 26% of our cohort received care discordant with practice guidelines. In multivariable analysis, patients with stage IVC disease (odds ratio 2.59, 95% confidence interval 1.66-4.04) were more likely to receive guidelines-discordant care when compared with those with stage II-IVB disease. The most common treatment deviation for those with stage I disease was overtreatment with chemoradiation therapy. Receiving guidelines-discordant care was associated with an increased risk of death (hazard ratio 1.46, 95% confidence interval 1.25-1.69).\Question: Is receipt of Care Discordant with Practice Guidelines Associated with Compromised Overall Survival in Nasopharyngeal Carcinoma?
[A]:
Many patients with stages I and IVC nasopharyngeal carcinoma do not receive care in accordance with practice guidelines. Receiving guidelines-discordant care is associated with compromised overall survival in the USA.
