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.

Ex Input:
Context: The goals of this study were to evaluate the complication rate for intraoperative placement of a long-term central venous catheter (CVC) using intraoperative ultrasound (US) and fluoroscopy and to examine the feasibility for eliminating routine postprocedure chest X-ray.', 'Retrospective data pertaining to operative insertion of long-term CVC were collected and the rate of procedural complications was determined.', 'From January 2008 to August 2013, 351 CVCs were placed via the internal jugular vein using US. Of these, 93% had a single, successful internal jugular vein insertion. The complications included 4 arterial sticks (1.14%). Starting in October 2012, postprocedure chest radiography (CXR) was eliminated in 170 cases, with no complications. A total of $29,750 in charges were deferred by CXR elimination.
Answer: This review supports the use of US for CVC placement with fluoroscopy in reducing the rate of procedural complications. Additionally, with fluoroscopic imaging, postprocedural CXR can be eliminated with associated healthcare savings.

Ex Output:
Does image-guided placement of long-term central venous catheters reduce complications and cost?

Context: To determine the prevalence of fathers' attendance at pretest cancer genetic counseling sessions with mothers undergoing BRCA1/2 genetic testing for hereditary breast/ovarian cancer (HBOC) risk, and to identify psychosocial and other correlates of fathers' attendance.", 'One hundred and twenty-one fathers of minor-age children who were spouses/partners of women (mothers) undergoing such counseling and testing were recruited, completed a behavioral self-report survey, and provided data about their sociodemographic backgrounds, father-child cancer communication histories, parenting relationship quality, and information-seeking and perceived knowledge.', 'A total of 27.3% of fathers attended pretest cancer genetic counseling with mothers. Compared to fathers who did not attend pretest cancer genetic counseling, those who did had stronger parenting alliances with mothers, were more likely to have sought out information about BRCA1/2 testing, and felt more informed about testing. In an adjusted logistic regression model of session attendance, the strength of the parenting alliance was associated with a 6% increase in the likelihood of attending genetic counseling (odds ratio [OR]=1.06, 95% confidence interval [CI]=1.01, 1.12, p<.05) and greater perceived knowledge about BRCA1/2 testing was associated with a four-fold increase in the likelihood of session attendance (OR=4.03, CI=1.77, 9.37, p<.001).
Answer: One in three fathers attend pretest cancer genetic counseling with mothers undergoing BRCA1/2 testing; those who do have closer parenting relationships and are more informed about BRCA1/2 testing.

Ex Output:
Does prevalence and correlate of mothers and fathers attending pretest cancer genetic counseling together?

Context: Recent research has reported that high sugar diets increase insulin resistance, without abdominal obesity, in male, but not female Wistar rats. Whether a high sucrose (SU) diet increased insulin resistance in ovariectomized (OVX) rats was determined.', 'Female Sprague Dawley rats, weighing 273 +/- 20 g, had either an ovariectomy or a sham operation (sham). OVX and sham rats were divided into two groups: one group had a 68 En% SU diet and the other a 68 En% starch (ST) diet for 8 weeks.', 'The body weight was higher in the OVX than the sham rats, regardless of dietary carbohydrate subtype. The fasting serum glucose levels did not differ according to diet and ovariectomy. However, the fasting serum insulin levels were higher in the OVX than the sham rats, and in the OVX rats, a high SU diet increased the serum insulin levels more than a high ST diet. The whole body glucose disposal rates, which referred to the state of insulin sensitivity, were lower in the OVX rats fed both the high SU and ST diets, compared to sham rats. Glycogen deposits in the soleus and quadriceps muscles were lower in the OVX rats fed high SU and ST diets than in sham rats. The glucose transporter 4 content and fraction velocity of glycogen synthase in muscles showed similar glucose disposal rates. However, the triacylglycerol content in the muscles were higher in the OVX rats with a high SU diet than those with a high ST diet.
Answer: These results suggested that an OVX increased the weight gain due to higher food intakes, regardless of dietary carbohydrate subtypes. OVX-induced obesity may be involved in the induction of insulin resistance from an increased triacylglycerol content, decreased glucose uptake and glycogen synthesis in skeletal muscles, regardless of dietary carbohydrate subtypes.

Ex Output:

Does a high carbohydrate diet induce insulin resistance through decreased glucose utilization in ovariectomized rats?
