Expectations and emotions concerning infant transitions to ECEC : international dialogues with parents and teachers

Although a large body of literature recognises the impact of parent-teacher relationships on infant everyday experiences, less is known about the emotional experience and associated expectations of the adults themselves during earliest transitions. In the context of a multi-site international investigation across five countries–Brazil, Finland, Scotland, New Zealand, and the United States–the present paper examines teacher and parent interviews to reveal expectations prior to and after the transition to ECEC, highlighting the associated emotions that arise during this process. Irrespective of whether expectations are met, parents universally express insecurities and fears in relation to the transition. Parents are aware of the impact that the various aspects of the ECEC setting have on their child, and acknowledge difficulty in relinquishing control of the care of their child. Despite these concerns, parents consistently articulate their strong trust in the institution and the professional expertise of the staff. Correspondingly, teachers are keenly aware of the importance of their role in supporting families, and hold certain expectations for how the transition experience will play out accordingly. Regardless of country of context, the study shows that clear communication surrounding both centre and parental expectations establishes high levels of trust and ameliorates anxiety. Teacher-parent dialogues concerning routines, preferences, and anticipations are seen as pivotal in supporting a positive transition for all

Allelic Variants of Melanocortin 3 Receptor Gene (MC3R) and Weight Loss in Obesity: A Randomised Trial of Hypo-Energetic High- versus Low-Fat Diets

INTRODUCTION: The melanocortin system plays an important role in energy homeostasis. Mice genetically deficient in the melanocortin-3 receptor gene have a normal body weight with increased body fat, mild hypophagia compared to wild-type mice. In humans, Thr6Lys and Val81Ile variants of the melanocortin-3 receptor gene (MC3R) have been associated with childhood obesity, higher BMI Z-score and elevated body fat percentage compared to non-carriers. The aim of this study is to assess the association in adults between allelic variants of MC3R with weight loss induced by energy-restricted diets. SUBJECTS AND METHODS: This research is based on the NUGENOB study, a trial conducted to assess weight loss during a 10-week dietary intervention involving two different hypo-energetic (high-fat and low-fat) diets. A total of 760 obese patients were genotyped for 10 single nucleotide polymorphisms covering the single exon of MC3R gene and its flanking regions, including the missense variants Thr6Lys and Val81Ile. Linear mixed models and haplotype-based analysis were carried out to assess the potential association between genetic polymorphisms and differential weight loss, fat mass loss, waist change and resting energy expenditure changes. RESULTS: No differences in drop-out rate were found by MC3R genotypes. The rs6014646 polymorphism was significantly associated with weight loss using co-dominant (p = 0.04) and dominant models (p = 0.03). These p-values were not statistically significant after strict control for multiple testing. Haplotype-based multivariate analysis using permutations showed that rs3827103-rs1543873 (p = 0.06), rs6014646-rs6024730 (p = 0.05) and rs3746619-rs3827103 (p = 0.10) displayed near-statistical significant results in relation to weight loss. No other significant associations or gene*diet interactions were detected for weight loss, fat mass loss, waist change and resting energy expenditure changes. CONCLUSION: The study provided overall sufficient evidence to support that there is no major effect of genetic variants of MC3R and differential weight loss after a 10-week dietary intervention with hypo-energetic diets in obese Europeans

Children’s Initiatives in the Finnish Early Childhood Education Context

Pedagogical practices in early childhood education, which embrace children’s initiatives and agency, have been found to have an effect on children’s learning and competence skills. These initiatives can be seen crucial for children’s well-being and self-motivation. However, children’s initiatives are sometimes considered only as wants and that children are incapable to express meaningful initiatives in educational settings. In this chapter, we introduce children’s initiatives in their educational settings and examine the gap between children’s experiences and teachers’ observations. Children’s initiatives exist in a myriad of ways through the daily practices and processes that nourish motivation to ultimately create meanings through actions. It is essential to focus on children’s participation as it encourages and promotes agency and motivation within early childhood development.Peer reviewe

Cardiac lymphatics in health and disease

The lymphatic vasculature, which accompanies the blood vasculature in most organs, is indispensable in the maintenance of tissue fluid homeostasis, immune cell trafficking, and nutritional lipid uptake and transport, as well as in reverse cholesterol transport. In this Review, we discuss the physiological role of the lymphatic system in the heart in the maintenance of cardiac health and describe alterations in lymphatic structure and function that occur in cardiovascular pathology, including atherosclerosis and myocardial infarction. We also briefly discuss the role that immune cells might have in the regulation of lymphatic growth (lymphangiogenesis) and function. Finally, we provide examples of how the cardiac lymphatics can be targeted therapeutically to restore lymphatic drainage in the heart to limit myocardial oedema and chronic inflammation.Peer reviewe
