Given a passage classify if the passage has a definite objective/aim/goal or not. Output '1' if the passage has a defininte objective/aim/goal and output '0' if the passage does not have a definite objective/aim/goal.

In recent years, with the introduction of Enhanced Recovery After Surgery (ERAS) or Fast-Track protocols, perioperative care for colonic surgery has changed significantly. This is the experience of a single surgeon within a public hospital in New Zealand.', 'Between October 2005 and July 2007, consecutive patients undergoing segmental colonic resection by the senior author (AGH) were managed within a multimodal structured perioperative care pathway.', 'Thirty-two consecutive patients had elective colonic surgery without a stoma. Two were excluded because of cognitive impairment. The 30 remaining patients had a median age of 68.5 years (range 37-92) and a median daystay of 3 days (range 3-21). There were four (13%) readmissions, including one anastomotic leak.

Single nucleotide polymorphisms (SNPs) in approximately 40 genes have been associated with an increased risk for type 2 diabetes (T2D) in genome-wide association studies. It is not known whether a similar genetic impact on the risk of prediabetes (impaired glucose tolerance [IGT] or impaired fasting glycemia [IFG]) exists.', 'In our cohort of 1442 non-diabetic subjects of European origin (normal glucose tolerance [NGT] n\u200a=\u200a1046, isolated IFG n\u200a=\u200a142, isolated IGT n\u200a=\u200a140, IFG+IGT n\u200a=\u200a114), an impact on glucose homeostasis has been shown for 9 SNPs in previous studies in this specific cohort. We analyzed these SNPs (within or in the vicinity of the genes TCF7L2, KCNJ11, HHEX, SLC30A8, WFS1, KCNQ1, MTNR1B, FTO, PPARG) for association with prediabetes.', 'The genetic risk load was significantly associated with the risk for IGT (p\u200a=\u200a0.0006) in a model including gender, age, BMI and insulin sensitivity. To further evaluate potential confounding effects, we stratified the population on gender, BMI and insulin sensitivity. The association of the risk score with IGT was present in female participants (p\u200a=\u200a0.008), but not in male participants. The risk score was significantly associated with IGT (p\u200a=\u200a0.008) in subjects with a body mass index higher than 30 kg/m(2) but not in non-obese individuals. Furthermore, only in insulin resistant subjects a significant association between the genetic load and the risk for IGT (p\u200a=\u200a0.01) was found.

Patients generally die of cancer after the failure of current therapies to eliminate residual disease. A subpopulation of tumor cells, termed cancer stem cells (CSC), appears uniquely able to fuel the growth of phenotypically and histologically diverse tumors. It has been proposed, therefore, that failure to effectively treat cancer may in part be due to preferential resistance of these CSC to chemotherapeutic agents. The subpopulation of human colorectal tumor cells with an ESA(+)CD44(+) phenotype are uniquely responsible for tumorigenesis and have the capacity to generate heterogeneous tumors in a xenograft setting (i.e. CoCSC). We hypothesized that if non-tumorigenic cells are more susceptible to chemotherapeutic agents, then residual tumors might be expected to contain a higher frequency of CoCSC.', 'Xenogeneic tumors initiated with CoCSC were allowed to reach approximately 400 mm(3), at which point mice were randomized and chemotherapeutic regimens involving cyclophosphamide or Irinotecan were initiated. Data from individual tumor phenotypic analysis and serial transplants performed in limiting dilution show that residual tumors are enriched for cells with the CoCSC phenotype and have increased tumorigenic cell frequency. Moreover, the inherent ability of residual CoCSC to generate tumors appears preserved. Aldehyde dehydrogenase 1 gene expression and enzymatic activity are elevated in CoCSC and using an in vitro culture system that maintains CoCSC as demonstrated by serial transplants and lentiviral marking of single cell-derived clones, we further show that ALDH1 enzymatic activity is a major mediator of resistance to cyclophosphamide: a classical chemotherapeutic agent.
