TASK DEFINITION: Given a passage classify if the passage has a definite objective/aim/goal or not. Output '1' if the passage has a defininte objective/aim/goal and output '0' if the passage does not have a definite objective/aim/goal.
PROBLEM: Interfacility ground critical care transport (CCT) of patients by ambulance may be stressful. This study evaluated whether playing music during CCT reduces patient anxiety and whether objective evidence is manifested by a change in vital signs.', 'Urban teaching hospital.', 'In this prospective cohort study, music was played for eligible adult patients during CCT while recording vital signs. A questionnaire was subsequently mailed to patients to rate whether the ambulance transport was stressful, the impact music had on transport, whether music changed their anxiety, whether music made them comfortable and relaxed, and whether they would prefer music to be played on future transports. Vital signs were compared between respondents who perceived transport as stressful and those who did not.', 'One hundred two patients were enrolled; 23 respondents (22.5%) constituted the study group. Four patients (17.4%) reported CCT as stressful (average response, 4.75). Nineteen (82.6%) rated CCT as not stressful (average response, 1.63). Subjectively, patients reported a positive impact of music on transport, with improved comfort and relaxation but only a minimal decrease in anxiety. No statistically significant change in vital signs was observed between cohorts; too few patients were enrolled to generate power to detect any difference.

PROBLEM: Anxiety disorders increase risk of future cardiovascular disease (CVD) and mortality, even after controlling for confounds including smoking, lifestyle, and socioeconomic status, and irrespective of a history of medical disorders. While impaired vagal function, indicated by reductions in heart rate variability (HRV), may be one mechanism linking anxiety disorders to CVD, prior studies have reported inconsistent findings highlighting the need for meta-analysis.', 'Studies comparing resting-state HRV recordings in patients with an anxiety disorder as a primary diagnosis and healthy controls were considered for meta-analysis.', "Meta-analyses were based on 36 articles, including 2086 patients with an anxiety disorder and 2294 controls. Overall, anxiety disorders were characterized by lower HRV [high frequency (HF): Hedges' g=-0.29. 95% CI: -0.41 to -0.17, p<0.001; time domain: Hedges' g=-0.45, 95% CI: -0.57 to -0.33, p<0.001] than controls. Panic disorder (n=447), post-traumatic stress disorder (n=192), generalized anxiety disorder (n=68), and social anxiety disorder (n=90), but not obsessive-compulsive disorder (n=40), displayed reductions in HF HRV relative to controls (all ps<0.001).

PROBLEM: To evaluate whether anxiety-prone rats exposed to chronic water avoidance stress (WAS) develop visceral bladder hyperalgesia in addition to increased voiding frequency and anxiety-related behaviors.', 'Female Wistar-Kyoto (WKY) rats were exposed to chronic (10-day) WAS or sham paradigms. Referred hyperalgesia and tactile allodynia were tested using von Frey filaments applied to the suprapubic region and plantar region of the hindpaw, respectively. To confirm that suprapubic nociception represented referred visceral bladder hyperalgesia, we recorded abdominal visceromotor responses (VMR) to slow (100 l/min) and fast (1 cc/sec) bladder filling with room temperature or ice-cold saline. We assessed the development of hyperalgesia over the 10-day WAS protocol and the durability of increased pain sensations over time.', 'Animals exposed to chronic WAS had significantly lower hindpaw withdrawal thresholds post-stress and significant differences in referred hyperalgesia. Rats exposed to chronic WAS demonstrated an increased pain response to suprapubic stimulation and decreased response threshold to mechanical hindpaw stimulation by day 8 of the stress protocol, which persisted for more than one month. Animals exposed to chronic WAS showed increased VMR to fast filling and ice water testing in comparison to sham animals. Cystometry under anesthesia did not show increases in the frequency of non-voiding contractions.
