Introduction

Vaspin (visceral adipose tissue-derived serpin) was first described as an insulin-sensitizing adipose tissue hormone. Recently its anti-inflammatory function has been demonstrated. Since no appropriate data is available yet, we sought to investigate the plasma concentrations of vaspin in sepsis.

Materials and methods

57 patients in intensive care, fulfilling the ACCP/SCCM criteria for sepsis, were prospectively included in our exploratory study. The control group consisted of 48 critically ill patients, receiving intensive care after trauma or major surgery. Patients were matched by age, sex, weight and existence of diabetes before statistical analysis. Blood samples were collected on the day of diagnosis. Vaspin plasma concentrations were measured using a commercially available enzyme-linked immunosorbent assay.

Results

Vaspin concentrations were significantly higher in septic patients compared to the control group (0.3 (0.1-0.4) ng/mL vs. 0.1 (0.0-0.3) ng/mL, respectively; P < 0.001). Vaspin concentration showed weak positive correlation with concentration of C-reactive protein (CRP) (r = 0.31, P = 0.002) as well as with SAPS II (r = 0.34, P = 0.002) and maximum of SOFA (r = 0.39, P < 0.001) scoring systems, as tested for the overall study population.

Conclusion

In the sepsis group, vaspin plasma concentration was about three-fold as high as in the median surgical control group. We demonstrated a weak positive correlation between vaspin and CRP concentration, as well as with two scoring systems commonly used in intensive care settings. Although there seems to be some connection between vaspin and inflammation, its role in human sepsis needs to be evaluated further.Key words: adipocytokine, inflammation, vaspin, CRP, intensive care  相似文献

In this article, three librarians from Santa Fe College, the community college winner of the 2015 ACRL Excellence in Academic Libraries Award, share their successful work in information literacy instruction. While the ACRL award is given for overall achievement, this article focuses upon their creative and varied approaches to instruction, incorporating a wide blend of strategies to reach students across the college. Beginning with targeted approaches to virtual instruction, including broad use of the flipped classroom model, and building in active learning techniques, the librarians at Santa Fe College have built an instruction program that could serve as a model to community college libraries across the country.  相似文献

Staffing rural and remote schools is an important policy issue for the public good. This paper examines the private issues it also poses for teachers with families working in these communities, as they seek to reconcile careers with educational choices for children. The paper first considers historical responses to staffing rural and remote schools in Australia, and the emergence of neoliberal policy encouraging marketisation of the education sector. We report on interviews about considerations motivating household mobility with 11 teachers across regional, rural and remote communities in Queensland. Like other middle-class parents, these teachers prioritised their children's educational opportunities over career opportunities. The analysis demonstrates how teachers in rural and remote communities constitute a special group of educational consumers with insider knowledge and unique dilemmas around school choice. Their heightened anxieties around school choice under neoliberal policy are shown to contribute to the public issue of staffing rural and remote schools.  相似文献

The present study evaluated the effects of the On‐Task in a Box intervention on student on‐task behavior when used as a class‐wide intervention. The intervention package includes self‐monitoring, video modeling, and reinforcement contingency components. A multiple baseline design across three elementary classrooms was used to determine the effects of the intervention on student behavior. Results indicated immediate increases in on‐task behavior in all classrooms. Calculation of nonoverlap of all pairs’ effect sizes indicated strong intervention and maintenance effects on on‐task behavior of students in all classrooms. Social validity data were also collected, which indicated adequate validity of the intervention. Results of the study suggest that the intervention package may be effective for improving class‐wide levels of on‐task behavior.  相似文献

The authors explore the impact of a 3‐week homestay cultural immersion on 10 counselor trainees by analyzing their 210 structured journals using consensual qualitative research. Findings suggest that establishing meaningful relationships and engaging in critical reflection are central to increasing multicultural awareness. Implications for multicultural counseling training and research are provided.  相似文献

Many formal policies have suggested that officers need a college degree; however, policies forced little change in practices of American police organizations. Six hundred-fifty patrol officers employed in 12 medium-sized police departments in three Midwestern states were surveyed as to their current educational attainment and job performance. The purpose of this study was to determine the relationship between educational level and police performance.  相似文献
