TASK DEFINITION: Given a passage, construct a question on the basis of the information present in the passage. Construct the question in such a way that (i) it is unambiguous, (ii) it is answerable from the passage, (iii) its answer is unique (iv) it answer uses text phrases from the passage. Avoid creating questions that (i) can't be answered correctly without actually understanding the passage and (ii) uses the same words or phrases given in the passage.
PROBLEM: Research has shown that hand gestures affect comprehension and production of speech at semantic, syntactic, and pragmatic levels for both native language and second language (L2). This study investigated a relatively less explored question: Do hand gestures influence auditory learning of an L2 at the segmental phonology level?', 'To examine auditory learning of phonemic vowel length contrasts in Japanese, 88 native English-speaking participants took an auditory test before and after one of the following 4 types of training in which they (a) observed an instructor in a video speaking Japanese words while she made syllabic-rhythm hand gesture, (b) produced this gesture with the instructor, (c) observed the instructor speaking those words and her moraic-rhythm hand gesture, or (d) produced the moraic-rhythm gesture with the instructor.', 'All of the training types yielded similar auditory improvement in identifying vowel length contrast. However, observing the syllabic-rhythm hand gesture yielded the most balanced improvement between word-initial and word-final vowels and between slow and fast speaking rates.

SOLUTION: Does effects of hand gestures on auditory learning of second-language vowel length contrast?

PROBLEM: To describe the epidemiology of acute hand injuries and hand infections and to describe the factors associated with the transfer of these patients to a level 1 trauma center. In addition, we sought to understand management before transfer.', 'Retrospective review of patients with hand trauma or hand infection transferred to our level 1 trauma center from May 2009 to August 2011. We also identified hospitals with emergency departments (EDs) in our region and surveyed ED providers in these hospitals with regard to acute hand care.', 'A level 1 trauma center in the United States.', 'Four hundred sixty consecutive transfers for acute hand care.', 'The average patient age was 38. Most were male (84%), uninsured (51%), and from another county (59%). The average distance of transfer was 51 miles, and 80% were transferred by ground ambulance. The most common reasons for transfer were amputations (24%), infections (21%), lacerations (17%), and fractures/dislocations (16%). Of the 345 hospitals with an ED surveyed, 71% never had hand surgery coverage.

SOLUTION: Do lack of Acute Hand Care in the Southwest United States?

PROBLEM: To define whether laparoscopic gastric banding or laparoscopic Roux-en-Y gastric bypass represents the better approach to treat patients with morbid obesity.', 'Two techniques, laparoscopic gastric bypass or gastric banding, are currently widely used to treat morbid obesity. Since both procedures offer certain advantages, a strong controversy exists as to which operation should be proposed to these patients. Therefore, data are urgently needed to identify the best therapy.', 'Since randomized trials are most likely not feasible because of the highly different invasiveness and irreversibility of these procedures, a matched-pair design of a large prospectively collected database appears to be the best method. Therefore, we used our prospective database including 678 bariatric procedures performed at our institution since 1995. A total of 103 consecutive patients with laparoscopic gastric bypass were randomly matched to 103 patients with laparoscopic gastric banding according to age, body mass index, and gender.', 'Both groups were comparable regarding age, gender, body mass index, excessive weight, fat mass, and comorbidites such as diabetes, heart disease, and hypertension. Feasibility and safety: All gastric banding procedures were performed laparoscopically, and one gastric bypass operation had to be converted to an open procedure. Mean operating time was 145 minutes for gastric banding and 190 minutes for gastric bypass (P < 0.001). Hospital stay was 3.3 days for gastric banding and 8.4 days for gastric bypass. The incidence of early postoperative complications was not significantly different, but late complications were significantly more frequent in the gastric banding group (pouch dilatation). There was no mortality in both groups. Efficiency: Body mass index decreased from 48.0 to 36.8 kg/m in the gastric banding group and from 47.8 to 31.9 kg/m in the gastric bypass group within 2 years of surgery. These differences became significant from the first postoperative month until the end of the follow-up (24 months). The gastric bypass procedure achieved a significantly better reduction of comorbidities.

SOLUTION:
Is laparoscopic gastric bypass superior to laparoscopic gastric banding for treatment of morbid obesity?
