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.

Input: Consider Input: Context: There are few studies of quality interventions to mitigate the risk of transfusion-associated circulatory overload (TACO). Our aim was to reduce TACO risk in patients admitted to internal medicine at our hospital, by addressing gaps in transfusion practice.', 'A 3-month baseline audit of red blood cell (RBC) transfusion orders was conducted. An intervention consisting of a transfusion order set and physician checklist was developed and implemented based on identified gaps, followed by a 3-month post-intervention audit. Compliance with appropriateness criteria for RBC transfusion was ascertained, along with documentation of transfusion rate, diuretic usage and consent.', 'A total of 97 transfusion orders from 68 inpatients and 95 orders from 62 inpatients were audited in the baseline and post-intervention groups, respectively. Compliance with appropriateness criteria was similar pre- and post-intervention (87 versus 85%, P = 0·81). Specification of transfusion rate improved (84 versus 98%, P < 0·01), and diuretics were appropriately ordered more frequently for patients with TACO risk factors (37 versus 64%, P < 0·01). Timing of diuretics shifted from between or post-transfusion to pre-transfusion (35 versus 86%, P < 0·01), without increases in hypokalemia or acute kidney injury. No case of TACO was observed during the study. Documentation of specific risks discussed during consent discussion improved (4 versus 23%, P < 0·01).
Answer: A checklist and order set are tools that can improve the quality of transfusion orders by increasing the judicious use of pre-transfusion diuretics and augmenting the specification of transfusion rate. These interventions could be adapted to electronic order formats to improve transfusion safety.

Output: Do an order set and checklist improve physician transfusion ordering practices to mitigate the risk of transfusion-associated circulatory overload?


Input: Consider Input: Context: Reduced fertilization rates in women with minor endometriosis may be the result of direct effects on the ovary or to primary dysfunction within the hypothalamic-pituitary-ovarian axis. This controlled study was designed to examine the steroidogenic potential of luteinized granulosa cells in women with minor endometriosis.', 'Granulosa cells were harvested at oocyte recovery and incubated for 3 hr in increasing concentrations of luteinizing hormone (LH). The dissociation constant for added concentrations of LH was computed (as Km LH) and the results were compared between women with endometriosis and controls.', 'Women with minor endometriosis had a higher dissociation constant than women with tubal damage [Km 0.98 (0.58-9.24) versus 0.33 (0.28-0.72) ng/mL, P = 0.019], indicating reduced sensitivity to LH.
Answer: In women with endometriosis, granulosa cells were less sensitive to LH stimulation. This provides further evidence for primary ovarian dysfunction as a significant contributory cause of the associated subfertility.

Output: Are pre-ovulatory granulosa cells of infertile women with endometriosis less sensitive to luteinizing hormone?


Input: Consider Input: Context: Current serum testing for the detection of prostate cancer (PCa) lacks specificity. On diagnosis, the optimal therapeutic pathway is not clear and tools for adequate risk assessment of localized PCa progression are not available. This leads to a significant number of men having unnecessary diagnostic biopsies and surgery. A search for novel tumor markers identified macrophage inhibitory cytokine 1 (MIC-1) as a potentially useful marker. Follow-up studies revealed MIC-1 overexpression in local and metastatic PCa whereas peritumoral interstitial staining for MIC-1 identified lower-grade tumors destined for recurrence. Consequently, we sought to assess serum MIC-1 measurement as a diagnostic tool.', 'Using immunoassay determination of serum MIC-1 concentration in 1,000 men, 538 of whom had PCa, we defined the relationship of MIC-1 to disease variables. A diagnostic algorithm (MIC-PSA score) based on serum levels of MIC-1, total serum prostate-specific antigen, and percentage of free prostate-specific antigen was developed.', 'Serum MIC-1 was found to be an independent predictor of the presence of PCa and tumors with a Gleason sum > or =7. We validated the MIC-PSA score in a separate population and showed an improved specificity for diagnostic blood testing for PCa over percentage of free prostate-specific antigen, potentially reducing unnecessary biopsies by 27%.
Answer: Serum MIC-1 is an independent marker of the presence of PCa and tumors with a Gleason sum of > or =7. The use of serum MIC-1 significantly increases diagnostic specificity and may be a future tool in the management of PCa.


Output: Does measurement of serum levels of macrophage inhibitory cytokine 1 combined with prostate-specific antigen improve prostate cancer diagnosis?
