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.

[EX 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?
[EX A]: The experiment was only brief and a non-clinical sample was used.

[EX Q]: Context: Earlier exposure to laparoscopic techniques is thought to be beneficial for medical students. Reports have demonstrated that practice improves performance in laparoscopies. In this study, we intended to evaluate whether medical students' interest in surgery is affected by the amount of practice and the performance on a laparoscopic simulator.", 'A laparoscopic simulation curriculum was introduced at Taipei Medical University, Wan-Fang Medical Center. Study participants included 36 sixth-year and 14 seventh-year students who were divided according to whether they had indicated an interest (group A) or not (group B) in surgery. The students had twice-a-week practice sessions for 2 weeks. They underwent baseline measurement (BM) before training and posttraining measurement (PTM). Self-guided practice on the simulator was allowed. The learning outcomes were assessed comparing the BM and PTM scores by using the interquartile range (IQR) test. We also tested the correlation between total score and number of self-guided practice sessions.', 'All study participants showed improvement. No differences were observed between BM and PTM scores and between 6th- and 7th-year medical students. Significant differences were found in PTM scores between groups A and B (P < .001). Analysis of variance with a post hoc test for different groups revealed that the PTMs were significantly higher for both the 6th- and 7th-year medical students in group A than for those in group B (P < .001). Total performance scores were improved with a higher number of self-guided practice sessions. Linear regression analysis demonstrated a significant correlation between the number of self-guided practice sessions and total performance score (P < .001).\Question: Does students ' Interest in Surgery affect Laparoscopic Practicing Performance?
[EX A]: Those clerks and interns interested in surgery who had more sessions for self-guided practice, displayed more improvement than those not interested in surgery did. Improvement in performance correlated highly with trainees' number of self-guided practice sessions.

[EX Q]: Context: During cardiopulmonary resuscitation (CPR), myocardial blood flow generated by chest compression rarely exceeds 35% of its normal level. Cardiac output generated by chest compression decreases gradually with the prolongation of cardiac arrest and resuscitation. Early studies have demonstrated that myocardial blood flow during CPR is largely dependent on peripheral vascular resistance. In this study, we investigated the effects of chest compression in combination with physical control of peripheral vascular resistance assisted by tourniquets on myocardial blood flow during CPR.', 'Ventricular fibrillation was induced and untreated for 7 min in ten male domestic pigs weighing between 33 and 37 kg. The animals were then randomized to receive CPR alone or a tourniquet assisted CPR (T-CPR). In the CPR alone group, chest compression was performed by a miniaturized mechanical chest compressor. In the T-CPR group, coincident with the start of resuscitation, the thin elastic tourniquets were wrapped around the four limbs from the distal end to the proximal part. After 2 min of CPR, epinephrine (20 g/kg) was administered via the femoral vein. After 5 min of CPR, defibrillation was attempted by a single 150 J shock. If resuscitation was not successful, CPR was resumed for 2 min before the next defibrillation. The protocol was continued until successful resuscitation or for a total of 15 min. Five minutes after resuscitation, the elastic tourniquets were removed. The resuscitated animals were observed for 2h.', 'T-CPR generated significantly greater coronary perfusion pressure, end-tidal carbon dioxide and carotid blood flow. There was no difference in both intrathoracic positive and negative pressures between the two groups. All animals were successfully resuscitated with a single shock in both groups. There were no significant changes in hemodynamics observed in the animals treated in the T-CPR group before-and-after the release of tourniquets at post-resuscitation 5 min.\Question: Does a tourniquet assisted cardiopulmonary resuscitation augment myocardial perfusion in a porcine model of cardiac arrest?
[EX A]:
T-CPR improves myocardial and cerebral perfusion during CPR. It may provide a new and convenient method for augmenting myocardial and cerebral blood flow during CPR.
