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.

We designed an assessment and education program which was delivered to patients prior to first outpatient appointment for bariatric surgery. We hypothesised that this program would streamline care and would lead to improved weight loss following bariatric surgery.', 'The program incorporates a structured general practitioners (GP) review, a patient information evening and an on-line learning package. It was introduced in September 2012. Patient flow through the program was recorded. Outcomes of the new program were compared with contemporaneously treated patients who did not undertake the pre-hospital program.', 'All 636 patients on the waiting list for first appointment at the Alfred Health bariatric surgery clinic were invited to participate. There were 400 patients ultimately removed from the waiting list for first appointment. Of the remaining 236 patients, 229 consented to participate in the new program. The mean BMI was 47.8\u2009±\u20099.2. The fail to attend first appointment rate dropped from 12 to 2.1\xa0%. At 12\xa0months post-bariatric surgery, patients who undertook the new program (n\u2009=\u200982) had a mean excess weight loss (EWL) of 41.1\u2009±\u200920.3\xa0% where as those treated on the standard pathway (n\u2009=\u200961) had a mean EWL 32\u2009±\u200918.0\xa0% (p\u2009=\u20090.012).
Does a Pre-Hospital Patient Education Program improve Outcomes of Bariatric Surgery?

It has already been demonstrated that the rat esophagus produces retinoic acid from retinol. In this study, this process is further characterized and the effect of acetaldehyde examined to elucidate the possible mechanisms behind the epidemiological evidence that the incidence of esophageal cancer is higher in alcoholics.', 'Rat esophageal samples were incubated with all-trans retinal and newly formed all-trans retinoic acid (ATRA) was quantified using high-performance liquid chromatography (HPLC). Furthermore, beta-nicotinamide adenine dinucleotide (NAD)-dependent acetaldehyde oxidation by the rat esophagus was examined by tracing NAD reduction using a spectrophotometer.', 'Rat esophageal samples produced ATRA from all-trans retinal in a NAD-dependent manner and the potential was significantly attenuated by phenetyl isothiocynate, an ALDH inhibitor, or acetaldehyde depending on the concentration used. Rat esophageal samples also oxidized acetaldehyde of various concentrations NAD dependently. The ATRA formation potential that was temporarily inhibited by acetaldehyde was recovered to the control level by dialysis when the specimen was incubated with up to 50 microM of acetaldehyde.
Does acetaldehyde inhibit the formation of retinoic acid from retinal in the rat esophagus?

This research note discusses a common misconception in speech science and speech-language pathology textbooks that rib torque (i.e., rotational stress) assists resting tidal expiration and conversational speech production.', 'The nature of this misconception is considered.

Does rib torque assist resting tidal expiration or most conversational speech expiration?
