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 Input:
Context: The aim of this study was to examine the efficacy and surgical success rates of amniotic membrane (AM) transplantation performed for corneal perforation closure using a novel technique.', 'This study included 6 eyes from 6 patients with corneal perforation who had received AM transplantation between May 2011 and April 2012. The AM was collected from human placenta shortly after cesarean section. In surgery, the AM was folded into pleats and used to plug the wound using 10-0 nylon suture. The wound was then covered with an AM seal. After reepithelialization and AM scarring, sutures were removed.', 'All 6 patients had successful wound closure with 1 surgery. One patient underwent optical keratoplasty later, and 1 patient required combined preserved sclera transplantation. The absolute value of astigmatism decreased to <3.50 diopters (D) 3 months after surgery and to <3.00 D 6 months after surgery in patients with peripheral AM transplants. The visual acuity gradually improved over the first 3 months after surgery, and visual acuity gains were maintained at the 6-month postoperative mark.\Question: Do '' Pleats fold '' technique of amniotic membrane transplantation for management of corneal perforations?

Ex Output:
The AM transplantation procedure may be an effective option for treating corneal perforations when the wound is circular or irregular, except for incised wounds. Our "Pleats Fold" AM transplantation technique can achieve definite closure and effectively repair wounds of various sizes. Postoperative astigmatic values were acceptable. Therefore, we recommend this procedure for repairing lesions <3 mm in diameter that do not involve the central cornea and that are infection free.

Ex Input:
Context: To assess the ability of an adult risk screening questionnaire (RSQ), previously shown to predict attendance at hospital emergency departments, to identify impaired quality of life in adult patients with asthma in general practice.', 'Baseline data from an RCT of asthma clinics in general practice, using the St. George Respiratory Questionnaire (SGRQ) to measure quality of life.', 'Twelve general practices in Adelaide, Australia.', 'A total of 184 adult asthmatics were recruited, with a mean (standard deviation) age of 50.3 years (16.6 years). Age, gender, weight, number of comorbidities, smoking status, FEV1 and percent predicted FEV1 (pre-and post-bronchodilator), peak flow (pre and post), and RSQ were independently related to SGRQ scores. After adjusting for potential confounders, an RSQ score predictive of hospital attendance was also associated with an average increase (worsening) in SGRQ total score of 11.9 (95% CI: 7.6, 16.3), an average increase in activity score of 9.0 (2.5, 15.5), symptom score of 14.8 (8.6, 21.0), and impact score of 13.1 (8.6, 17.6). These represent clinically significant differences.\Question: Does hospital attendance prediction tool also identify impaired quality of life in adults with asthma in general practice?

Ex Output:
An RSQ score predictive of hospital attendance should alert the general practitioner to explore and address symptom, activity, and impact domains associated with impaired quality of life in adult asthma.

Ex Input:
Context: Patients with MHI and a positive head computed tomography (CT) scan frequently have a routine repeat head CT (RRHCT) to identify possible evolution of the head injury requiring intervention. RRHCT is ordered based on the premise that significant injury progression may take place in the absence of clinical deterioration.', 'In a Level I urban trauma center with a policy of RRHCT, we reviewed the records of 692 consecutive trauma patients with Glasgow Coma Scale scores of 13-15 and a head CT (October 2004 through October 2005). The need for medical or surgical neurologic intervention after RRHCT was recorded. Patients with a worse and unchanged RRHCT were compared, and independent predictors of a worse RRHCT were identified by stepwise logistic regression.', 'There were 179 patients with MHI and RRHCT ordered. Of them, 37 (21%) showed signs of injury evolution on RRHCT and 7 (4%) required intervention. All 7 had clinical deterioration preceding RRHCT. In no patient without clinical deterioration did RRHCT prompt a change in management. A Glasgow Coma Scale score less than 15 (13 or 14), age higher than 65 years, multiple traumatic lesions found on first head CT, and interval shorter than 90 minutes from arrival to first head CT predicted independently a worse RRHCT.\Question: Is routine repeat head CT for minimal head injury unnecessary?

Ex Output:
RRHCT is unnecessary in patients with MHI. Clinical examination identifies accurately the few who will show significant evolution and require intervention.
