Activity of metalloproteinases and adiponectin in obese patients— a possible factor of incisional hernias after bariatric procedures

Purpose

Metalloproteinases are a key component of the pathogenesis of abdominal hernias. Obesity is considered a risk factor in herniogenesis and hernia recurrence. The aim of this study was to evaluate the serum concentrations of metalloproteinase-2 (MMP-2), MMP-9, MMP-13, and adiponectin in morbidly obese and nonoverweight controls.

Materials and methods

The participants were recruited from among patients undergoing bariatric and non-bariatric surgery and divided into two groups: I (body mass index (BMI)≥35 kg/m², n=40) and II (BMI<25 kg/m², n=30). Serum concentrations of MMP-2, MMP-9, MMP-13, and adiponectin were measured using enzyme-linked immunosorbent assay (ELISA).

Results

A statistically significant difference between groups was observed for MMP-2 concentration. The median MMP-9 concentration was higher in the obese group, but the difference was not statistically significant. Median MMP-13 concentrations did not differ between groups. Serum adiponectin concentration was insignificantly higher in the non-obese group.

Conclusions

The elevated serum MMP-2 and MMP-9 concentrations in obese individuals may be related to the higher incidence of incisional hernias in this population.

     

Evaluation of the non‐formal forest education sector in the state of North Rhine‐Westphalia,Germany: organisations,programmes and framework conditions

Although a large number of different organisations offer various forest education programmes within Germany, specific information (i.e., sectoral and programme content and provision at a state level) is lacking. This study used a survey of all 61 forest education organisations (43 respondents) in the state of North Rhine‐Westphalia, Germany, to evaluate its forest education sector, with a specific focus on the organisations, demand for its services, forest educational programmes and framework conditions. Input from expert interviews was also used to develop recommendations. The study indicates that, especially with children as the main target group, many non‐formal programmes are offered to support the formal environmental education sector and to promote leisure activities in the forest. Yet, despite a high demand for forest education, low personnel resources restrict the number of visits and activities, principally owing to limited financial resource. We also discuss the provision of innovative new educational programmes and supplementary services, combined with increased quality management, that could be beneficial to the future development of the sector in NRW.     

Teaching critical thinking: an investigation of a task in introductory macroeconomics

This paper is an investigation of understandings of critical thinking from two teaching perspectives: academic staff and tutors. It explores critical thinking as situated within an assessment task in introductory macroeconomics. This study found that while the two academic staff conceptualized critical thinking as a set of concrete cognitive skills, the tutors challenged this notion. Although tutors used the way of understanding critical thinking identified by the academic staff in their teaching and marking, they also discussed broader notions of critical thinking that they saw as a fundamental aspect of the discipline. The paper examines the multiple constructions of critical thinking in this setting and its broader implications.     

Common legacy,different paths: the transformation of educational systems in the Czech Republic,Slovakia, Hungary and Poland

The goal of this work is to better understand the institutional changes in the educational systems of the Czech Republic, Hungary, Poland and Slovakia. We demonstrate that the educational reforms implemented during the transformation introduced very different institutional arrangements in the four countries, despite the fact that their systems shared many common characteristics at the beginning of the 1990s. Differences between the national approaches to educational reforms are particularly reflected in the modes of education decentralisation, the level of school autonomy, accountability and funding mechanisms. We believe that different institutional arrangements may have contributed to the divergent achievements of the Czech Republic, Slovakia, Hungary and Poland in the PISA programme.     

Revisiting free school meal eligibility as a proxy for pupil socio‐economic deprivation

Whether someone has ever had free school meal (FSM) eligibility over a six‐year period is the measure of socio‐economic disadvantage currently used in the English school system. It is used to monitor the socio‐economic gap in achievement in the education system, to identify particular children at risk of low achievement and to direct funding to particular children and schools. In this paper we assess how well this measure predicts pupil attainment in secondary school in comparison to other measures of socio‐economic background known to influence pupil attainment, such as parental education or income. We ask whether the FSM measure is an adequate proxy for a pupil's socio‐economic disadvantage in an educational context. To do this we draw on the Longitudinal Study of Young People in England and matched administrative data. We find that the FSM eligibility measure correlates highly with other measures of socio‐economic disadvantage, however it does not identify all children living in what would be deemed deprived households. We then compare the extent to which the FSM eligibility measure predicts educational achievement relative to other measures of deprivation and find that its predictive power is only marginally lower than many richer survey measures. This provides some reassurance on its use in policy.     

Enhancing quality with a research-based student feedback instrument: a comparison of veterinary students’ learning experiences in two culturally different European universities

This paper explores the value of a research-based student inventory from the quality assurance point of view in two culturally different European higher education institutions for veterinary education. Perceived heavy workload is a well-known problem in veterinary studies and is a challenge to the quality of learning. First- and third-year students in both institutions responded to an inventory consisting of items regarding their approaches to learning, self-efficacy, study workload and the teaching-learning environment. There were differences in students’ approaches to learning and perceived workload between the two institutions. In both contexts, the strongest predictor of the workload turned out to be the surface approach to learning. Self-efficacy showed a positive correlation with the deep approach to learning and organised studying. The strengths of the teaching-learning environment varied between the institutions. Moreover, the present study discusses how the gained information could be used in improving the teaching-learning environment and students’ learning.
