Krüppel-like factor 10 (KLF10) is a tumor suppressor in multiple cancers. In a murine model of spontaneous pancreatic adenocarcinoma (PDAC), additional KLF10 depletion accelerated distant metastasis. However, Klf10 knockout mice, which suffer from metabolic disorders, do not develop malignancy. The mechanisms of KLF10 in PDAC progression deserve further exploration. KLF10-depleted and KLF10-overexpressing PDAC cells were established to measure epithelial-mesenchymal transition (EMT), glycolysis, and migration ability. A murine model was established to evaluate the benefit of genetic or pharmacological manipulation in KLF10-depleted PDAC cells (PDACshKLF10). Correlations of KLF10 deficiency with rapid metastasis, elevated EMT, and glycolysis were demonstrated in resected PDAC tissues, in vitro assays, and murine models. We identified sirtuin 6 (SIRT6) as an essential mediator of KLF10 that modulates EMT and glucose homeostasis. Overexpressing SIRT6 reversed the migratory and glycolytic phenotypes of PDACshKLF10 cells. Linoleic acid, a polyunsaturated essential fatty acid, upregulated SIRT6 and prolonged the survival of mice injected with PDACshKLF10. Modulating HIF1α and NFκB revealed that EMT and glycolysis in PDAC cells were coordinately regulated upstream by KLF10/SIRT6 signaling. Our study demonstrated a novel KLF10/SIRT6 pathway that modulated EMT and glycolysis coordinately via NFκB and HIF1α. Activation of KLF10/SIRT6 signaling ameliorated the distant progression of PDAC.

BackgroundClostridium difficile infection (CDI) is a nosocomial condition prevalent in patients with hematological disorders. We aimed to identify the risk factors associated with the devel-opment of CDI and assess the mortality rate at 15 and 30 days among hematologic patients admitted to a tertiary care center.MethodsWe conducted a retrospective case-control study from January 2010 to December 2015. Forty-two patients with hematologic malignancy and CDI, and 84 with hematologic dis-ease and without history of CDI were included in the case and control groups, respectively.ResultsUnivariate analysis revealed that episodes of febrile neutropenia [odds ratio (OR), 5.5; 95% confidence interval (CI), 2.3‒12.9; P<0.001], admission to intensive care unit (OR, 3.8; 95% CI, 1.4‒10.2; P=0.009), gastrointestinal surgery (OR, 1.2; 95% CI, 1.1‒1.4; P<0.001), use of therapeutic (OR, 6.4; 95% CI, 2.5‒15.9; P<0.001) and prophylactic antibiotics (OR, 4.2; 95% CI, 1.6‒10.7; P=0.003) in the last 3 months, and >1 hospital-ization (OR, 5.6; 95% CI, 2.5‒12.6; P<0.001) were significant risk factors. Multivariate analysis showed that use of therapeutic antibiotics in the last 3 months (OR, 6.3; 95% CI, 2.1‒18.8; P=0.001) and >1 hospitalization (OR, 4.3; 95% CI, 1.7‒11.0; P=0.002) were independent risk factors. Three (7.1%) and 6 (14.2%) case patients died at 15 and 30 days, respectively.ConclusionThe risk factors for developing CDI were exposure to therapeutic antibiotics and previous hospitalization. Hematological patients who developed CDI had higher early mortality rates, suggesting that new approaches for prevention and treatment are needed.
Exploring Possible Variations of Classroom Interaction in Kindergarten and First - Grade Classrooms

As a small but significant response to current Educational Reform in Taiwan, the study initiates a three-way discussion on the forms and contents of classroom interaction among a college associate professor(the observer), a kindergarten teacher and a first-grade teacher to seek ways to create the $quot;real discussion$quot; in classrooms. The researcher (along with two research assistants) observed and videotaped classroom interactions in the two classrooms weekly, showed some portions of the videotapes to the two classroom teachers every month. After four months` fieldwork, the observation was narrowed down to focus on the Chinese lessons in the first-grade classroom and the diary-picture sharing and discussion time in the kindergarten classroom. While both teachers mentioned the difficulties in making the whole class participate in discussion, after the first three-way discussion session, we have observed changes happening in both classrooms. The first-grade teacher had students teach part of the lesson in turn, that is, acting as $quot;small teachers$quot; to lead the discussion. The kindergarten teacher had the children name their peers to ask questions after talking about their diary-pictures. While students are gaining more opportunities to talk and to lead the discussion, there remain some problems to be solved, such as the teachers` overarching concern of keeping up with the curriculum schedule and the children`s ability in extending the contents of discussion. Teachers` prominent $quot;fear$quot; of letting students talk have to be understood from a more distant context, such as the expectation of teacher role and student role in Taiwan`s culture. Nevertheless, the joint sense-making process in which the three teachers inform one another as to how to organize classroom interaction might provide insights to kindergarten-elementary school transition issues in Taiwan.

Background: Nurses are the most visible, frontline personnel providing health education to patients. In particular, nurse experience with Pap examinations have the potential to influence women's attitudes toward screening for cervical cancer. However, nurses in Taiwan have lower rates of Pap testing than the general population. Understanding the factors predicting nurse intent to have a Pap exam and Pap exam status would inform interventions and policies to increase their Pap exam uptake. Therefore, the present study was undertaken. Materials and Methods: Data were collected by questionnaire from a convenient sample of 504 nurses at a regional hospital in central Taiwan between August and October 2011 and analyzed by descriptive statistics, confirmatory factor analysis, and logistic regression. Results: Nurse intention to have a Pap exam was predicted by younger age, less negative attitudes toward Pap exams, and greater influence of others recommendations. However, nurses were more likely to actually have had a Pap exam if they were older, married, had sexual experience, and had a high intention to have a Pap exam. Conclusions: Nurses who are younger than 34 years old, unmarried, sexually inexperienced, and with low intention to have a Pap exam should be targeted with interventions to educate them not only about the importance of Pap exams in detecting cervical cancer, but also about strategies to decrease pain and embarrassment during exams. Nurses with less negative attitudes and experiences related to Pap exams would serve as role models to persuade women to have Pap exams, thus increasing the uptake rate of Pap exams in Taiwan.

Background: The prevalence of esophageal cancer (EC) with second primary cancers (SPC) is increasing worldwide. This study was aimed to understand the clinical features of EC patients with SPC in the Taiwanese population. Materials and Methods: Clinical and laboratory data for 180 EC patients with or without SPC were collected between January 2009 and December 2013. Information on treatment approaches, location of SPCs and ABO blood type were also collected and stratified. Results: The most common SPC in EC patients was hypopharyngeal cancer, followed by laryngeal cancer and hepatocellular carcinoma in our study. Malignancies of colon, prostate and lung were also found. There was a significant higher portion of blood type A in the EC patients with SPC compared with those without (42.4% vs 19.5%, P=0.006). Conclusions: The frequency and SPC site distribution and blood type A should be considered in clinical evaluation of EC patients with a high risk of developing SPC in the Taiwanese population.
