Disordered eating attitudes are rapidly increasing, especially among young women in their twenties. These disordered behaviours result from the interaction of several factors, including beauty ideals. A significant factor is social media, by which the unrealistic beauty ideals are popularized and may lead to these behaviours. The objectives of this study were, first, to determine the relationship between disordered eating behaviours among female university students and sociocultural factors, such as the use of social network sites, beauty ideals, body satisfaction, body image and the body image desired to achieve and, second, to determine whether there is a sensitive relationship between disordered eating attitudes, addiction to social networks, and testosterone levels as a biological factor. The data (N = 168) was obtained using validated surveys (EAT-26, BSQ, CIPE-a, SNSA) and indirect measures of prenatal testosterone. The data was analysed using chi-square, Student’s t-test, correlation tests and logistic regression tests. The results showed that disordered eating attitudes were linked to self-esteem (p < 0.001), body image (p < 0.001), body desired to achieve (p < 0.001), the use of social media (p < 0.001) and prenatal testosterone (p < 0.01). The findings presented in this study suggest a relationship between body image, body concerns, body dissatisfaction, and disordered eating attitudes among college women.

Background: People worldwide are concerned with the possibility of climate change, microplastics, air pollution, and extreme weather affecting human health. Countries are implementing measures to reduce environmental impacts. Nurses play a vital role, primarily through Green Teams, in the process of promoting sustainable practices and minimizing the environmental footprint of health care facilities. Despite existing knowledge on this topic, assessing nurses’ environmental awareness and behavior, including the barriers they face, is crucial with regard to improving sustainable health care practices. Aim: To analyze the environmental awareness and behavior of nurses, especially nurse leaders, as members of the Green Team and to identify areas for improvement with regard to the creation of a sustainable environment. Methods: A sequential mixed-method study was conducted to investigate Spanish nurses. The study utilized an online survey and interviews, including participant observation. An online survey was administered to collect quantitative data regarding environmental awareness and behavior. Qualitative interviews were conducted with environmental nurses in specific regions, with a focus on Andalusia, Spain. Results: Most of the surveyed nurses (N = 314) exhibited moderate environmental awareness (70.4%), but their environmental behavior and activities in the workplace were limited (52.23% of participants rarely performed relevant actions, and 35.03% indicated that doing so was difficult). Nurses who exhibited higher levels of environmental awareness were more likely to engage in sustainable behaviors such as waste reduction, energy conservation, and environmentally conscious purchasing decisions (p < 0.05). Additionally, the adjusted model indicated that nurses’ environmental behavior and activities in the workplace depend on the frequency of their environmental behaviors outside work as well as their sustainable knowledge (p < 0.01). The results of the qualitative study (N = 10) highlighted certain limitations in their daily practices related to environmental sustainability, including a lack of time, a lack of bins and the pandemic. Additionally, sustainable environmental behavior on the part of nursing leadership and the Green Team must be improved. Conclusions: This study revealed that most nurses have adequate knowledge, attitudes, and behaviors related to environmental sustainability both inside and outside the workplace. Limitations were associated with their knowledge and behaviors outside of work. This study also highlighted the barriers and difficulties that nurses face in their attempts to engage in adequate environmental behaviors in the workplace. Based on these findings, interventions led by nurses and the Green Team should be developed to promote sustainable behaviors among nurses and address the barriers and limitations identified in this research.

Specific learning disorders affect a significant portion of the population. A total of 80% of its instances are dyslexia, which causes significant difficulties in learning skills related to reading, memorizing and the exposition of concepts. Whereas great efforts have been made to diagnose dyslexia and to mitigate its effects at primary and secondary school, little has been done at the university level. This has resulted in a sensibly high rate of abandonment or even of failures to enroll. The VRAIlexia project was created to face this problem by creating and popularizing an innovative method of teaching that is inclusive for dyslexic students. The core of the project is BESPECIAL, a software platform based on artificial intelligence and virtual reality that is capable of understanding the main issues experienced by dyslexic students and to provide them with ad hoc digital support methodologies in order to ease the difficulties they face in their academic studies. The aim of this paper is to present the conceptual design of BESPECIAL, highlighting the role of each module that composes it and the potential of the whole platform to fulfil the aims of VRAIlexia. Preliminary results obtained from a sample of about 700 dyslexic students are also reported, which clearly show the main issues and needs that dyslexic students experience and these will be used as guidelines for the final implementation of BESPECIAL.

Higher Educational Institutions (HEIs) are responsible for creating healthy and sustainable environments for students and teachers through diverse educational paradigms such as gamification. In this sense, the Healthy People 2030 and the Sustainable Development Goals indicated the imperative to provide inclusive and equitable quality education to promote a healthy environment and life. The principal objective was to analyse the impact of gamification on health development in HEIs, highlighting their positive and negative effects. To achieve such an objective, a bibliometric analysis was carried out. The 257 documents showed no significant increasing trend in the last decade (p > 0.05) related to the pandemic. Most of the publications were conferences (45%), and the few published articles were the documents with more citations (p < 0.001). According to their index in Journal Citation Reports, there were significant differences between the citations of articles published in journals (p < 0.001). The analysis of journal co-citations showed that the leading journals (such as Computers in Human Behavior) had a significant part in the clusters formed (p < 0.001), conditioning also the keywords, especially the term “motivation”. These findings were discussed, concluding that the experimental studies focused on the teachers’ adverse effects are yet to come.

A continuous precipitation and filtration flow system coupled on-line with an atomic absorption spectrometer for the quantitative pre-concentration and determination of lead at the micrograms per litre level is described. Pb^II forms a precipitate with ammonia, which is retained on a stainless-steel filter and then dissolved by a stream of nitric acid. A concentration factor of up to 700 is achieved. Several calibration graphs suited to the degree of enrichment are proposed for the determination of lead(II) in the range 1.2–1500 ng ml^–1; sampling rates of 1–15 h^–1 and relative standard deviations of less than 3.6% are afforded by the proposed method, which has been satisfactorily applied to the determination of lead in tap water.
