Abstract
Because edible insects (EI) have been, in recent years, recommended as a nutritious animal protein food with enormous environmental advantages over other sources of animal protein for human consumption, studies aimed at investigating the consumer perspective have become more prominent. Hence, this study intended to examine the perceptions of participants from different countries about the commercialization and economic and social impacts of edible insects. The study was made using a questionnaire survey, and data were collected in Brazil, Croatia, Greece, Latvia, Lebanon, Lithuania, Mexico, Poland, Portugal, Romania, Serbia, Slovenia, Spain, and Turkey. The final number of received answers was 7222 participants. For the treatment of the results, different statistical techniques were used: factor analysis, internal reliability by Cronbach's alpha, cluster analysis, ANOVA to test differences between groups, and Chi-square tests. The results obtained confirmed the validity of the scale, constituted by 12 out of the 14 items initially considered, distributed by 4 factors: the first related to the economic impact of EIs, the second related to the motivation for consumption of EIs, the third related to the places of purchase of EIs, and the fourth corresponding to a question presented to the participants as a false statement. A cluster analysis allowed identifying three clusters, with significant differences between them according to all the sociodemographic variables tested. Also, it was found that the participants expressed an exceptionally high level of agreement with aspects such as the difficulty in finding EIs on sale, knowledge acting as a strong motivator for EI consumption, and the role of personalities and influencers in increasing the will to consume EIs. Finally, practically all sociodemographic variables were found to be significantly associated with perceptions (country, sex, education, living environment, and income), but not age. In conclusion, the perceptions about EI commercialization were investigated and revealed differences among samples originating from different countries. Moreover, the sociodemographic characteristics of the participants were found to be strongly associated with their perceptions.

Abstract
Objective: Understanding the impact of stress on emotional and external eating behaviors and the psychological and the associated metabolic factors can help in designing subsequent interventions to protect health. In particular, psychological trait-like construct related to eating has been shown to be an important target for intervention. Methods and measures: This study aimed to investigate the biochemical variables associated with a decrease in emotional and external eating behaviors due to 12-week ketogenic diet (12KD) in 35 adult participants (12 males) with obesity. Results: Absolute changes in emotional and external eating were independent of changes in body mass, nutritional intake, and Δ cortisol, but were predicted with increases in serum β-hydroxybutyrate (BHB) and decreases in serum peripheral neuropeptide Y (pNPY) (all p's < 0.050). Decrease in pNPY was also associated with an increase in BHB but was independent of anthropometrical changes, Δ fasting glucose, and Δ insulin. Conclusion: The reductions in emotional and external eating behaviors in participants with obesity were uniquely predicted by an increase in BHB and a decrease in pNPY after 12KD. In ketosis, emotional and external eating dropped independently of body mass change. Change in pNPY predicted changes in emotional and external eating. The role of BHB in modulating eating behavior should be further explored.

Abstract
Formal education is crucial for the development of nurses’ professional identity and can play a decisive role in attracting students to the nursing profession. This is even more important during a public health emergency such as the COVID-19 pandemic. This study aimed to investigate nursing students’ attitudes and feelings toward their future profession and academic studies during the first COVID-19 lockdown. A cross-sectional, descriptive study was conducted on 361 nursing students. The data were collected through the Students’ attitudes toward the nursing profession during the COVID-19 outbreak scale, and the Satisfaction with online learning scale. Nursing students expressed higher levels of commitment and dedication to their profession compared to perceived job security. They were generally satisfied with their distance learning experience in terms of accessibility of study materials, adaptation of lectures and quality of communication with academic staff. However, students perceived the ICT-supported distance learning as moderately effective. Students’ satisfaction with online learning was positively related to their perceived professional commitment. In times of health crisis, faculties should consider students’ perceived quality of nursing education and attitudes toward future profession to promote appropriate professional identity.

Abstract
Food consumption involves several dimensions, being some of them directly associated with the consumers' characteristics. The interrelationships between these domains impact consumer behaviour for food choice and the consequent decisions for food consumption. In these frameworks, economic motivations are determinant. On the other hand, the scientific literature highlights that the economic-based stimuli to choose food is still underexplored. In this perspective, the objective of this study was to assess the main sociodemographic and anthropometric determinants of the economic motivations for food choice. For that, a questionnaire survey was carried out involving 11,919 respondents from 16 countries. A validated questionnaire was used, translated into the native languages in all participating countries, using a back-translation process. First, the information obtained was assessed through factor analysis to reduce the number of variables associated with the economic motivations and to identify indexes. After, and considering the indexes obtained as dependent variables, a classification and regression tree analysis was performed. As main insights, it is highlighted that the main determinants of the economic motivations are country of residence, age, gender, civil state, professional activity, educational level, living environment, responsibility for buying food, weight, height, body mass index, healthy diets and physical exercise practices. Additionally, the results also reveal that economic motivations may be associated with two indexes, one related to convenience attitudes and the other to quality concerns. Finally, the younger persons and the women are the social groups more concerned with healthy diets and food quality. In conclusion, this work confirmed that food choice is to a high extent influenced by several sociodemographic and behavioural factors.

Abstract
BACKGROUND Many risk factors lead to opioid use and drug-related problems. One of the challenges to understand behavioural factors, drug problems and psychopathology is to identify biological markers that are suitable for research on broad substance abuse and dependence involving human participants. AIMS The study has examined the relationships between the self-reported childhood history of trauma, parental bonding, psychopathology, impulsivity, current resiliency, two neuropeptides, possible markers of behaviour and emotion regulation, and severity of drug-related problems. METHODS One hundred and sixty-seven individuals with a history of opioid use completed questionnaires. Serum neuropeptide Y (NPY) and substance P (SP) levels were analysed. Moderating and mediating relationships between variables were examined using structural equation modelling (SEM). RESULTS Antisocial features, depression, impulsivity, SP, NPY, emotional neglect and resilience are associated with severity of drug-related problems. SP is associated with antisocial personality traits. CONCLUSIONS The novelty of this study is the proposed possible link between biochemical markers, antisocial features and behavioural and emotional regulation. Serum NPY and SP levels have a potential to be used as a biomarker in opioid users before and in the treatment process to account for interactions between biological vulnerabilities and childhood risk factors in predicting behavioural adjustment and more severe drug-related problems.

Abstract
BACKGROUND Individuals with long-term chronic body image dissatisfaction may experience excessive stress and negative cognitions and feelings. Changes in negative cognition about body image are often reported as outcomes of obesity treatment. In turn, body image dissatisfaction also influences behavioural adherence and success in weight loss. OBJECTIVES The purpose of the present study was to elucidate psychological changes during 6 months of lifestyle behaviour intervention and the association of these changes with actual weight loss. METHODS The study examined associations between body image dissatisfaction and obesity treatment-related variables among 33 overweight and obese adults (age = 38.9 ± 6.5 years) participating in a 6-month diet and exercise weight loss intervention. Measurements of body image dissatisfaction and anthropometric variables were taken at baseline and after 6-months. DISCUSSION Significant improvements were observed in all physical variables (e.g. weight, percentage of body fat mass, waist and hip circumference) after intervention. Body image dissatisfaction improved significantly over the treatment, and these changes were associated with changes in obesity indicators. CONCLUSIONS Changes in weight and body image probably influence each other dynamically. Results from this study support the inclusion of cognitive intervention aimed at improving body image in weight management programs.

Abstract
The ketogenic diet (KD) is being increasingly promoted as a strategy to fight obesity. Although the KD is effective for weight loss and weight control, comprehensive determination of its relationship with biochemical, physiological and psychological changes is still largely unexplored. We hypothesized that a 12-week KD (12KD) would significantly affect body weight, physical performance, cognitive function, eating behaviors, the metabolic and hormonal profile in obese adults, although differently in men and women. In an uncontrolled intervention, 35 sedentary obese adults (13 men, 25 women), aged 37 ± 7 years with a BMI 36.1 ± 5.6 kg/m2 underwent a 12KD between March 2017 and June 2017 at the University of Primorska. The 12KD resulted in decreased appetite, significant weight loss of participants (-18 ± 9 kg men vs. -11 ± 3 kg women; P < .001), decreased emotional and external eating (P < .001 for both), increased body image satisfaction (P < .001) and improved physical performance (P < .001). Biochemically, a significant drop in glucose (P = .026), and a significant increase in LDL-cholesterol (P = .031), CRP (P = .007), and BDNF (P = .035) were observed in the first 2 weeks; then, all listed parameters returned to baseline. On the other hand, a significant reduction in insulin (P < .001) and leptin levels (P < .001), and a significant increase in adiponectin (P = .008) and NPY (P = .009) were detected throughout the duration of the 12KD. Our results show the efficacy of the 12KD on weight loss, physical performance, cognitive function, eating behaviors and metabolic profile. However, the long-term effects of a KD on these outcomes needs to be further studied before general recommendations can be made.

Abstract
Body dissatisfaction may play some role in the pathophysiology of chronic diseases. This study examined relations between body dissatisfaction and circulating levels of inflammatory biomarkers C-reactive protein, tumour necrosis factor-α, interleukin-6 and anti-inflammatory adiponectin, and to explore positive changes in relevant lifestyle behaviour after these associations. A total of 33 asymptomatic overweight men and women were evaluated at the baseline and after a 6-month lifestyle behaviour intervention. Body dissatisfaction emerged as an important predictor of pro- and anti-inflammatory biomarkers and may promote the production of inflammatory cytokines by reducing the level of anti-inflammatory and increasing the level of pro-inflammatory cytokine production.

Abstract
PURPOSE Low-grade systemic inflammation due to obesity is considered to be the key link between obesity and obesity-related disorders. The hypothesis was tested that significant alterations in inflammatory markers and adipokines would occur over a multidisciplinary intervention and that these changes might also be important for improvement of cardiovascular risk factors. METHODS Thirty-tree overweight adults completed a 6-month multidisciplinary intervention program to evaluate the effects of a personalized dietary program based on the individual's resting metabolic rate (RMR) on anthropometric parameters, aerobic and anaerobic capabilities, metabolic profile, inflammation, and body image satisfaction. Body composition, physical activity, anaerobic capabilities, RMR, metabolic profile, and low-grade inflammation were measured. Diet composition and body image dissatisfaction were also assessed. RESULTS After 6 months of multidisciplinary intervention the participants showed significantly decreased body weight, waist circumference (WC), and the inflammatory markers tumor necrosis factor-α, C-reactive protein, and visfatin. They also showed increased anti-inflammatory adiponectin and consequently decreased serum insulin, HOMA-IR, and total cholesterol. The important findings of the study were that reduction of sugars and saturated fatty acids in the diet, coupled with an increase in exercise, significantly correlated with reduction of WC and body mass index. In addition, positive correlations between ∆ BMI, ∆ WC, ∆ trunk fat, inflammation, and cardiovascular risk factors were demonstrated. CONCLUSIONS Weight loss in combination with increased physical activity, a negative energy balance, and diet adjustment was associated with lower inflammation and consequently with lower cardiovascular risk factors.

Abstract
OBJECTIVE Evidence suggests that body dissatisfaction may relate to biological processes and that negative cognitions can influence physical health through the complex pathways linking psychological and biological factors. DESIGN The present study investigates the relationships between body image satisfaction, inflammation (cytokine levels), aerobic fitness level and obesity in 96 middle-aged men and women (48 normal and 48 overweight). All participants underwent measurements of body satisfaction, body composition, serological measurements of inflammation and aerobic capabilities assessment. RESULTS Body image dissatisfaction uniquely predicted inflammation biomarkers, C-reactive protein and tumour necrosis factor-α, even when controlled for obesity indicators. Thus, body image dissatisfaction is strongly linked to inflammation processes and may promote the increase in cytokines, representing a relative metabolic risk, independent of most traditional risk factors, such as gender, body mass index and intra-abdominal (waist to hip ratio) adiposity. CONCLUSION Results highlight the fact that person's negative cognitions need to be considered in psychologically based interventions and strategies in treatment of obesity, including strategies for health promotion. Results contribute to the knowledge base of the complex pathways in the association between psychological factors and physical illness and some important attempts were made to explain the psychological pathways linking cognitions with inflammation.
