Given a passage with a context and an answer, 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.

Context: To establish a novel approach for quick and high throughput verification of human gene imprinting.', "By use of a pair of dye-labeled probes, 5' nuclease assay was combined with reverse transcriptase-PCR(RT-PCR) to genotype a coding single nucleotide polymorphism (cSNP), rs705(C/T) of a known imprinted gene, small nuclear ribonucleotide protein N (SNRPN), on both genomic DNA and cDNA of human lymphoblast cell lines.", 'Allele discrimination showed a clear monoallelic expression pattern of SNRPN, which was confirmed by RT-PCR based restriction fragment length polymorphisms. Pedigree analysis verified the paternal origin of expressed allele, which is in consistency with previous report.
Answer: Coding SNP is an ideal marker for detecting gene imprinting by 5' nuclease assay. This approach has also a potentiality to discover differential allele expression of non-imprinted genes in order to find gene cis-acting functional polymorphism.
Is [ Coding single nucleotide polymorphism an ideal marker for detecting gene imprinting by 5 ' nuclease assay ]?

Context: Completeness of cytoreduction is a significant predictor of long-term outcome after cytoreductive surgery (CRS) and hyperthermic intraperitoneal chemotherapy (HIPEC). Imaging has limited sensitivity to identify peritoneal metastases and therefore predict whether complete cytoreduction is possible. We reviewed our experience using laparoscopy to determine candidates for complete cytoreduction and HIPEC.', 'This single-center, retrospective study examined patients from 2007 to 2014 who underwent laparoscopy to determine complete cytoreduction (CC-0/1)/HIPEC candidacy. Preoperative, intraoperative, and postoperative data were collected.', 'A total of 145 laparoscopies were performed on 141 patients, 72 (51.1\xa0%) of whom were female, with a median age of 53\xa0years (range 20-79). The primary site was appendiceal in 67 (47.5\xa0%) patients, colorectal in 43 (30.5\xa0%), mesothelioma in 17 (12.1\xa0%), unknown in 9 (6.4\xa0%), small bowel in 3 (2.1\xa0%), gastric in 1, and ovarian in 1 (0.7\xa0% each). Overall, 115 (81.6\xa0%) patients had prior abdominal surgery, 111 (76.6\xa0%) had evidence of disease on imaging, and 117 (80.7\xa0%) underwent prior chemotherapy, with a median of 5.9\xa0weeks between the last treatment and laparoscopy (0.9-498.9\xa0weeks). Four (2.8\xa0%) intraoperative complications were observed (one liver laceration, two enterotomies, and one air embolus), and nine (6.2\xa0%) postoperative complications [four (2.8\xa0%) Clavien grade (CG) I, three (2.8\xa0%) CG II, one (0.7\xa0%) CG III (return to operating room) and one (0.7\xa0%) CG IV (transient ischemic attack)]. Forty-eight patients deemed candidates by laparoscopy underwent CRS/HIPEC (positive predictive value 82.8\xa0%).
Answer: Diagnostic laparoscopy is a safe, feasible, and accurate staging tool in patients with suspected peritoneal metastases being considered for CRS.
Is laparoscopy Safe and Accurate to Evaluate Peritoneal Surface Metastasis Prior to Cytoreductive Surgery?

Context: To describe the prevalence and correlates of hazardous drinking among female sex workers (FSWs) at 13 sites throughout Mexico.', 'FSWs (N = 1089) who were enrolled in a brief sexual risk reduction intervention (Mujer Segura) were queried about their sexual risk and substance use practices and their work contexts. Participants were classified as hazardous or non-hazardous drinkers based on the Alcohol Use Disorders test (AUDIT-C). Logistic regression models were used to examine individual, contextual, and community-level factors as correlates of hazardous drinking.', 'Ninety-two percent of participants reported alcohol consumption in the past month. Among drinkers (N = 1001), 83% met AUDIT-C criteria for hazardous drinking. Factors that were independently associated with hazardous drinking included: drug use in the past month (adjusted odds ratio (AOR) = 3.31; 95% CI 1.29-8.45), being a cigarette smoker (AOR = 1.71; 95% CI 1.13-2.58), being a barmaid or dance hostess (AOR = 3.40; 95% CI 1.95-5.91), alcohol use before or during sex with clients (AOR = 7.78; 95% CI 4.84-12.52), and working in a city with a higher marginalization index (AOR = 1.07; 95% CI 1.04-1.11).
Answer: Findings support the high prioritization by public health authorities of alcohol prevention and treatment programs for FSWs.
