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: Depression is a prevalent comorbidity of chronic respiratory disease (CRD), and may indicate worse clinical outcomes. The relationship between depression and living with chronic hypoxia due to CRD or residence at altitude has received little attention in resource-poor settings.', 'To investigate the association between CRD conditions and depressive symptoms in four settings in Peru.', 'We collected data on CRD and depressive symptoms in adults aged ⩾35 years. Depressive symptoms were measured according to the Center for Epidemiologic Studies Depression scale. Multivariable ordinal logistic regression was used to assess the adjusted odds of being in a higher category of depressive symptoms as a function of CRD.', 'We analyzed data from 2953 participants (mean age 55.3 years, 49% male). The prevalence of major depressive symptoms was 19%, with significant variation according to setting. Participants with at least one CRD (OR 1.34, 95%CI 1.06-1.69) and those living at altitude (OR 1.64, 95%CI 1.10-2.43) had an increased adjusted odds of being in a higher category of depressive symptoms.\Question: Are chronic respiratory disease and high altitude associated with depressive symptoms in four diverse settings?
[A]: We found a high prevalence of depressive symptoms, and a positive association between depressive symptoms with CRD and with living at altitude, both of which cause chronic hypoxia.


[Q]: 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?
[A]: 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.


[Q]: Context: Several studies on differences in infant outcome by socioeconomic position have been done, but these have usually been based on ad hoc data linkages. The aim of this paper was to investigate whether socioeconomic differences in perinatal health in Finland could be regularly monitored using routinely collected data from one single register.', 'Since October 1990, the Finnish Medical Birth Register (MBR) has included data on maternal occupation. A special computer program that converted the occupation name into an occupational code and into a socioeconomic position was prepared. Perinatal health was measured with five different indicators. The Finnish MBR data for years 1991 to 1999 (n=565 863 newborns) were used in the study. The study period was divided into three, three year periods to study time trends.', 'An occupational code was derived for 95% of women, but it was not possible to define a socioeconomic position for 22% of women, including, for example, students and housewives (the group "Others"). For the rest, the data showed socioeconomic differences in all perinatal health indicators. Maternal smoking explained up to half of the excess risk for adverse perinatal outcome in the lowest socioeconomic group. The socioeconomic differences narrowed during the 1990s: infant outcome improved in the lowest socioeconomic group, but remained at the same level or even deteriorated in other groups. When comparing the lowest group with the highest group, the odds ratios (OR) adjusted for maternal background characteristics at least halved for prematurity (from 1.32 (95% confidence intervals 1.24 to 1.43) in 1991-1993 to 1.16 (1.08 to 1.25) in 1997-1999), for low birth weight (from 1.49 (1.36 to 1.63) to 1.25 (1.17 to 1.40)), and for perinatal mortality (from 1.79 (1.44 to 2.21) to 1.33 (1.07 to 1.66)).\Question: Does register based monitoring show decreasing socioeconomic differences in Finnish perinatal health?
[A]:
Social inequality in perinatal health outcomes exists in Finland, but seems to have diminished in the 1990s. These data showed that routinely collected birth register data provide a good source for studies on socioeconomic health differences in the perinatal period, but that uncertainty, mainly attributable to the large group of women with difficult to classify socioeconomic status, remains.
