Designing ELF-aware lessons in high-stakes exam contexts

In ELT contexts, the concept of ELF awareness has been proposed as a means of developing the skills, strategies, and overall outlook that learners require to competently participate in ELF interactions. Depending on the teaching context, this can be a demanding process. We discuss the ELF-aware instructional interventions carried out by two practitioners working in high-stakes exam preparation contexts in Greece. These contexts are predominantly Standard English oriented. The interventions described an attempt to put into practice the principles of ELF-aware pedagogy, namely awareness of language and language use, awareness of instructional practice, and awareness of learning. The innovative aspect of these interventions is that they do not run contrary to the curriculum of these high-stakes exam preparation classes. On the contrary, they complement the courseware used in these contexts with authentic audiovisual materials and original metalinguistic activities that boost learners' self-confidence as ELF speakers and as candidates of these exams. © 2020 The Author(s)

Umbilical Venous Catheters and Peripherally Inserted Central Catheters: Are They Equally Safe in VLBW Infants? A Non-Randomized Single Center Study

Background and Objective: Peripherally inserted central catheters (PICC) and umbilical venous catheters (UVC) are frequently used for vascular access in neonatal intensive care units (NICUs). While there is a significant need for these devices for critically ill neonates, there are many complications associated with their use. We aimed at investigating the incidence of UVC and PICC complications in very low birth weight (VLBW) infants. Materials and Methods: This is an observational study performed with neonates of the tertiary General Hospital of Piraeus, Greece, during an 18 month-period. Seventy-one neonates were recruited and divided into two groups: 34 neonates with PICC and 37 neonates with UVC. We recorded: Catheter dwell time, the causes of catheter removal, other complications, infections, and catheter tip colonization rates. Results: No significant statistical differences were noticed between the 2 study groups with regards to demographic characteristics, causes for catheter removal, catheter indwelling time or the incidence of nosocomial infection. Eleven UVC tips and no PICC tips were proved colonized (p = 0.001) following catheter removal. Conclusions: The incidence of complications associated with the use of UVCs and PICCs in VLBW infants did not significantly differ in our study. Their use seems to be equally safe. Further studies, with larger samples, are necessary to confirm our results

Differential effect of Pistacia vera extracts on experimental atherosclerosis in the rabbit animal model: An experimental study

Background. Lipid-enriched diets and oxidative stress are risk factors for the development of atherosclerosis. The effects of the methanolic (ME) and cyclohexane (CHE) extracts of the Pistacia vera nut, often included in the Mediterranean diet, were studied in the rabbit model of atherosclerosis. Methods and results. Twenty-four New Zealand White rabbits received atherogenic diet (Control Group), supplemented with ME (Group ME) or CHE (Group CHE) for 3 months. Previously, a GC-MS and a UHPLC LC-DAD-ESI(-)-HRMS/MS method were developed to investigate the extracts' chemical profiles. Blood samples at baseline and monthly determined lipid profile, lipid peroxidation and liver function. The aorta, myocardium and liver were examined histologically at 3 months. Groups ME and CHE had significantly higher HDL- and non-significantly lower LDL-cholesterol median % changes from baseline than the Control Group. Triacylglycerol was significantly higher in Group CHE vs. Control. MDA values were significantly lower in Group ME vs. Control and CHE. ALT and AST were significantly higher in Group CHE vs. Control. -GT was lower in Group ME vs. Control. Aortic intimal thickness was significantly less in Groups ME and CHE vs. Control; Group ME atherosclerotic lesions were significantly less extensive vs. Groups Control and CHE. Only Group CHE had significant liver fatty infiltration. Conclusions. During short-term administration concomitantly with atherogenic diet, both P. vera extracts were beneficial on HDL-, LDL-cholesterol and aortic intimal thickness. The ME additionally presented an antioxidant effect and significant decrease of aortic surface lesions. These results indicate that P. vera dietary inclusion, in particular its ME, is potentially beneficial in atherosclerosis management. © 2010 Marinou et al

Outcome assessment of a complex mental health intervention in the workplace. Results from the MENTUPP pilot study

ObjectiveMulticomponent interventions are recommendable to achieve the greatest mental health benefits, but are difficult to evaluate due to their complexity. Defining long-term outcomes, arising from a Theory of Change (ToC) and testing them in a pilot phase, is a useful approach to plan a comprehensive and meaningful evaluation later on. This article reports on the pilot results of an outcome evaluation of a complex mental health intervention and examines whether appropriate evaluation measures and indicators have been selected ahead of a clustered randomised control trial (cRCT).MethodsThe MENTUPP pilot is an evidence-based intervention for Small and Medium Enterprises (SMEs) active in three work sectors and nine countries. Based on our ToC, we selected the MENTUPP long-term outcomes, which are reported in this article, are measured with seven validated scales assessing mental wellbeing, burnout, depression, anxiety, stigma towards depression and anxiety, absenteeism and presenteeism. The pilot MENTUPP intervention assessment took place at baseline and at 6 months follow-up.ResultsIn total, 25 SMEs were recruited in the MENTUPP pilot and 346 participants completed the validated scales at baseline and 96 at follow-up. Three long-term outcomes significantly improved at follow-up (p < 0.05): mental wellbeing, symptoms of anxiety, and personal stigmatising attitudes towards depression and anxiety.ConclusionsThe results of this outcome evaluation suggest that MENTUPP has the potential to strengthen employees’ wellbeing and decrease anxiety symptoms and stigmatising attitudes. Additionally, this study demonstrates the utility of conducting pilot workplace interventions to assess whether appropriate measures and indicators have been selected. Based on the results, the intervention and the evaluation strategy have been optimised
