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: Intrathecal magnesium sulfate coinfusion with morphine increases antinociception in normal rats; however, because magnesium also delays the onset of tolerance, it is not clear whether this additional antinociception is a result of potentiated analgesia or tolerance abatement. We examined the antinociceptive interaction of intrathecal (IT) bolus magnesium sulfate and morphine in morphine naive rats and those with mechanical allodynia after a surgical incision. After intrathecal catheter implantation, rats were given preinjections of magnesium or saline, followed by injections of morphine or saline. In morphine naïve rats, IT bolus magnesium sulfate 281 and 375 microg followed by IT morphine 0.25 or 0.5 nmol enhanced peak antinociception and area under the response versus time curve two-to-three-fold in the tail-flick test as compared with morphine alone. Likewise, in rats with incisional pain, IT bolus magnesium sulfate 188 and 375 microg followed by morphine 0.5 nmol reduced mechanical allodynia, whereas morphine 0.5 nmol alone did not. This study suggests that IT magnesium sulfate potentiates morphine at a spinal site of action.\Question: Does magnesium sulfate potentiate morphine antinociception at the spinal level?

Output: Magnesium sulfate potentiates morphine analgesia when coadministered intrathecally in normal rats, and in an animal model of mechanical allodynia after a surgical incision. These results suggest that intrathecal administration of magnesium sulfate may be a useful adjunct to spinal morphine analgesia.


Input: Consider Input: Context: The purpose of this study was to examine the effectiveness of ankle bracing and taping in preventing recurrencess of ankle sprains, specifically in female athletes.', "Varsity soccer players' medical records over a five-year period were retrospectively reviewed at a Division III women's college. Data were extracted regarding any history of ankle sprain(s), type of intervention used as prophylaxis after the ankle sprain, number of exposures, and any incidence of recurrence.", 'All collegiate varsity soccer players who had suffered a previous sprain to either one or both ankles (38 players) were identified as subjects.', 'Each previously injured ankle (n = 56) was considered as a case for the analysis. Ankles that had a previous sprain received one of four interventions: 1) a canvas, laced ankle brace (n = 19), 2) taping (n = 12), 3) a combination of taping and ankle bracing (n = 8), or 4) no treatment (n = 17).', 'The four intervention groups had a total of 1717 practice exposures and 650 competitive game exposures; exposures did not differ among the 4 groups. Ankle sprain recurrence frequency was 0%, 25%, 25%, and 35% for the braced, taped, combination, and untreated groups, respectively. The recurrence incidence for the braced group was significantly lower than that of the other three groups. The ankle sprain recurrence frequency did not differ among the taped, combination, and no treatment groups.\Question: Does ankle brace effectively reduce recurrence of ankle sprains in female soccer players?

Output: We suggest that prophylactic ankle bracing is effective in reducing the incidence of ankle sprains in female soccer players with a previous history of ankle sprains.


Input: Consider Input: Context: To identify the presence or absence of 38 postpartum hemorrhage preparedness elements in hospitals in New Jersey and Georgia as a component of the Postpartum Hemorrhage Project of the Association of Women's Health, Obstetric and Neonatal Nurses.", 'Quality improvement baseline assessment survey.', 'Hospitals (N = 95) in New Jersey and Georgia.', "Key informants were clinicians who were members of their hospitals' obstetric teams and were recognized as knowledgeable about their hospitals' postpartum hemorrhage policies.", "An electronic survey was sent by e-mail to each identified hospital's key informant.", 'The mean number of elements present was 23.1 (SD = 5.2; range = 12-34). Volume of births, students, magnet status, and other hospital characteristics did not predict preparedness. None of the hospitals had all of the 38 preparedness elements available. Less than 50% of the hospitals had massive hemorrhage protocols, performed risk assessments and drills, or measured blood loss. For every 10% increase in the total percentage of African American women who gave birth, there was a decrease of one preparedness element.\Question: Do postpartum Hemorrhage Preparedness Elements Vary Among Hospitals in New Jersey and Georgia?


Output: Objective measures of preparedness are needed, because perceptions of preparedness were inconsistent with the number of preparedness elements reported.
