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: To determine the role of factor V Leiden and prothrombin gene mutation in the pathogenesis of unexplained second and third trimester nonrecurrent fetal loss.', 'One hundred and fourteen women with unexplained nonrecurrent late fetal loss made up the study group, and 106 normal pregnant women with a history of delivery of at least one healthy fetus and no history of late fetal loss made up the control group. The study group was further divided into two subgroups: second (n = 36) and third (n = 78) trimester fetal loss. All women were tested for factor V Leiden and G20210A prothrombin gene mutations.', 'Twenty-one (18.4%) of the women in the study group and seven (6.6%) of the women in the control group were heterozygous carriers of factor V Leiden mutation (OR = 3.19). Eleven (9.6%) of the women in the study group and three (2.8%) of the women in the control group were heterozygous carriers of prothrombin gene mutation (OR = 3.66). In assessing with regard to trimesters, 18 (23%) factor V Leiden and 10 (12.8%) prothrombin gene mutations were present in the group of third trimester fetal loss (OR = 4.24 and OR = 5.04, respectively). Three (8.3%) factor V Leiden and one (2.7%) prothrombin gene mutation were detected in women with second trimester fetal loss (OR = 1.28 and OR = 0.40, respectively).\Question: Is third trimester nonrecurrent fetal loss associated with factor V Leiden and prothrombin gene mutations?

Output: Factor V Leiden and prothrombin gene mutations were associated with third trimester nonrecurrent fetal loss. These mutations should be screened in women with third trimester but not second trimester unexplained nonrecurrent late fetal loss.


Input: Consider Input: Context: To examine whether differences emerged when the Chinese version of the Movement-Specific Reinvestment Scale (MSRS-C) was administered to community-dwelling older adults with instructions to respond in the context of "general" movements, walking, using chopsticks or dressing. Furthermore, the difference between the six-point Likert scale and four-point Likert scale response formats of the MSRS-C was investigated.', 'The study was implemented in the community of Hong Kong with 52 older adults (mean age 77.4 years). Telephone interviews were carried out on two occasions for each participant. Participants provided a verbal response to each of 10 questions from the MSRS-C with different response formats (i.e., six-point or four-point Likert Scales) and different instructions in the response context (i.e. general, walking, using chopsticks, dressing). The sequence of response format and context was randomized for each participant.', 'Older fallers scored significantly higher on the MSRS-C (general) with six-point or four-point response formats than non-fallers. The MSRS-C (general) and MSRS-C (walking) were not statistically different, and showed good discriminative power for previous older fall status (older fallers or older non-fallers). However, MSRS-C (chopsticks) and MSRS-C (dressing) failed to differentiate older fallers from older non-fallers.\Question: Do instructions influence response to the Chinese version of the Movement-Specific Reinvestment Scale in community-dwelling older adults?

Output: Both the MSRS-C (general) and MSRS-C (walking) with a six-point or a four-point response format showed good discrimination of older fallers from non-fallers. Older adults might respond to the MSRS-C with respect to the most challenging movements (e.g. fall-related movements) in their daily living. Geriatr Gerontol Int 2015; ●●: ●●-●●.


Input: Consider Input: Context: Halogenated anesthetics depress left ventricular function, but their effects on the right ventricle have been less well studied. Therefore, the authors studied the effects of isoflurane and desflurane on pulmonary arterial (PA) and right ventricular (RV) properties at baseline and in hypoxia.', 'Right ventricular and PA pressures were measured by micromanometer catheters, and PA flow was measured by an ultrasonic flow probe. PA mechanics were assessed by flow-pressure relations and by impedance spectra derived from flow and pressure waves. RV contractility was assessed by end-systolic elastance (Ees), RV afterload was assessed by effective PA elastance (Ea), and RV-PA coupling efficiency was assessed by the Ees:Ea ratio. Anesthetized dogs were randomly assigned to increasing concentrations (0.5, 1, and 1.5 times the minimum alveolar concentration) of isoflurane (n = 7) or desflurane (n = 7) in hyperoxia (fraction of inspired oxygen, 0.4) and hypoxia (fraction of inspired oxygen, 0.1).', 'Isoflurane and desflurane had similar effects. During hyperoxia, both anesthetics increased PA resistance and characteristic impedance, increased Ea (isoflurane, from 0.82 to 1.44 mmHg/ml; desflurane, from 0.86 to 1.47 mmHg/ml), decreased Ees (isoflurane, from 1.09 to 0.66 mmHg/ml; desflurane, from 1.10 to 0.72 mmHg/ml), and decreased Ees:Ea (isoflurane, from 1.48 to 0.52; desflurane, from 1.52 to 0.54) in a dose-dependent manner (all P < 0.05). Hypoxia increased PA resistance, did not affect characteristic impedance, increased afterload, and increased contractility. During hypoxia, isoflurane and desflurane had similar ventricular effects as during hyperoxia.\Question: Do isoflurane and desflurane impair right ventricular-pulmonary arterial coupling in dogs?


Output: Isoflurane and desflurane markedly impair RV-PA coupling efficiency in dogs, during hyperoxia and hypoxia, both by increasing RV afterload and by decreasing RV contractility.
