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.

Input: Consider Input: Context: The greater omentum has been found to be immunologically competent in protecting abdominal organs from inflammation. Anastomotic omentoplasty has been used and proven effective in preventing anastomotic leaks after an esophagectomy. However, pulmonary complications are still a substantial problem after an esophagectomy. This study investigated the benefits of mediastinal transposition of the omentum, a modification of the conventional omental wrapping technique, in controlling overall postoperative intrathoracic complications.', "From January 2010 to March 2015, 208 consecutive patients receiving an open Ivor-Lewis esophagectomy at our institution were retrospectively reviewed. One hundred twenty-one patients with omentum mediastinal transposition were assigned to the transposition group and 87 patients without omental transposition were placed in the non-transposition group. The patients' demographics, postoperative short-term outcomes, and in-hospital cost were documented and analyzed.", 'Mediastinal transposition of the omentum led to a shorter postoperative hospital stay (14 vs. 16 d, P=0.038) and a lower intrathoracic infection rate (30.6% vs. 48.3%, P=0.009). Intrathoracic infection was milder in the transposition group (P=0.005), though a non-significant was found in overall complications (P=0.071). The multivariate logistic regression analyses identified omentum mediastinal transposition (P=0.007, OR=0.415) as an independent protective factor for postoperative intrathoracic infection. The total in-hospital cost was comparable in both groups (P>0.05), whereas the pharmacy cost was lower in the transposition group than in the non-transposition group (¥21,668 vs. ¥27,012, P=0.010).\Question: Does mediastinal transposition of the omentum reduce infection severity and pharmacy cost for patients undergoing esophagectomy?

Output: Mediastinal transposition of the omentum decreases the rate and severity of postoperative intrathoracic infection following an open Ivor-Lewis esophagectomy. This result in decreased pharmacy costs, rather than resulting in an increased economic burden sustained by surgical patients.


Input: Consider Input: Context: Helicobater (H.) pylori eradication rates with standard first-line triple therapy have declined to unacceptable levels. To date, amoxicillin-resistant H. pylori strains have rarely been detected. Whether increasing the dosage of amoxicillin in a standard 7 days eradicating regimen may enhance its efficacy is not known. The aim of this paper is to compare the efficacy of a 7 days high-dose amoxicillin based first-line regimen with sequential therapy.', 'We have retrospectively analyzed data from 300 sex and age matched patients, who underwent 3 different therapeutic schemes: (1) standard LCA, lansoprazole 30 mg bid, clarithromycin 500 mg bid and amoxicillin 1000 mg bid for 7 days; (2) high dose LCA (HD-LCA), lansoprazole 30 mg bid, clarithromycin 500 mg bid and amoxicillin 1000 mg tid for 7 days; (3) sequential LACT, lansoprazole 30 mg bid plus amoxicillin 1000 mg bid for 5 days, followed by lansoprazole 30 mg bid, clarithromycin 500 mg bid and tinidazole 500 mg bid for 5 days. Eradication was confirmed by 13C-urea breath test. Compliance and occurrence of adverse effects were also assessed.', 'Eradication rates were: 55% for LCA, 75% for HD-LCA and 73% for LACT. Eradication rates were higher in HD-LCA group compared to LCA (p<0.01), while no significant differences were observed in HD-LCA group compared to LACT (p=ns). Compliance and occurrence of adverse effects were similar among groups.\Question: Is high dose amoxicillin-based first line regimen equivalent to sequential therapy in the eradication of H. pylori infection?

Output: High-dose amoxicillin based eradicating treatment is superior to standard triple therapy and equivalent to sequential therapy; compared to the latter, the shorter duration may represent an advantage.


Input: Consider Input: Context: Work stress is associated with an increased risk for cardiovascular disease (CVD). Exaggerated cardiovascular reactivity to work-related stressors or incomplete recovery after work is a proposed mechanism underlying this increase in risk. This study examined the effects of work stress on 24-hour profiles of the pre-ejection period (PEP), a measure of cardiac sympathetic activity, obtained from ambulatory measurement of the impedance cardiogram.', "A total of 67 male white-collar workers (age 47.1 +/- 5.2) underwent ambulatory monitoring on 2 workdays and 1 non-workday. Work stress was defined according to Siegrist's model as 1) a combination of high effort and low reward at work (high imbalance) or 2) an exhaustive work-related coping style (high overcommitment).", 'High overcommitment was associated with shorter absolute PEP levels during all periods on all 3 measurement days, reduced wake-to-sleep PEP differences and reduced PEP variability, as indexed by the SD.\Question: Is overcommitment to work associated with changes in cardiac sympathetic regulation?


Output: Overcommitment to work was associated with an increase in basal sympathetic drive and a reduction in the dynamic range of cardiac sympathetic regulation. Both findings are compatible with the hypothesis that overcommitment induces beta-receptor down-regulation.
