Introduction: Eating disorders (EDs) are serious psychological problems that affect not only the individual, but also their entire environment. The prevalence rates of EDs are higher among the adolescent population. A better understanding of ED risk factors is essential to design effective prevention and intervention programs that focus beyond the areas of weight and appearance.Methods: The main objective of this systematic review was to identify the risk factors of EDs and provide a comprehensive approach, analyzing the interplay between individuals, their inner circle, and the society characteristics. The Web of Science, Scopus, CENTRAL and PsycInfo databases were searched.Results: The initial search produced 8,178 references. After removing duplicates and performing the selection process by three independent reviewers, 42 articles were included in the systematic review according to the pre-specified inclusion criteria. The results suggest the relevance of society and the inner circle on the development of EDs.Discussion: The internalization of the thin ideal, promoted by the current society, and living in an unsupportive, unaffectionate, non-cohesive environment were associated with the onset of EDs symptomatology. Other associated variables with this ED indicator were poor-quality relationships and feeling judged about appearance. These aspects seem to be essential for the development of individual characteristics like self-esteem or adaptative coping during adolescence. This systematic review has shown the complex etiology of EDs and the relevance of the interplay between the different areas involved. Furthermore, this information could be relevant to improve the design of innovative and more effective prevention and intervention programs.Systematic review registration: PROSPERO, identifier CRD42022320881.

Epidermolysis bullosa (EB) is an inherited disorder characterised by skin fragility and the appearance of blisters and wounds. Patient wounds are often colonised or infected with bacteria, leading to impaired healing, pain and high risk of death by sepsis. Little is known about the impact of bacterial composition and susceptibility in wound resolution, and there is a need for longitudinal studies to understand healing outcomes with different types of bacterial colonisation. A prospective longitudinal study of 70 wounds from 15 severe EB patients (Junctional and Recessive Dystrophic EB) from Chile. Wounds were selected independently of their infected status. Wound cultures, including bacterial species identification, composition and Staphylococcus aureus (SA) antibiotic susceptibility were registered. Wounds were separated into categories according to their healing capacity, recognising chronic, and healing wounds. Hundred‐one of the 102 wound cultures were positive for bacterial growth. From these, 100 were SA‐positive; 31 were resistant to Ciprofloxacin (31%) and only seven were methicillin‐resistant SA (7%). Ciprofloxacin‐resistant SA was found significantly predominant in chronic wounds (**P < .01). Interestingly, atoxigenic Corynebacterium diphtheriae (CD) was identified and found to be the second most abundant recovered bacteria (31/101), present almost always in combination with SA (30/31). CD was only found in Recessive Dystrophic EB patients and not related to wound chronicity. Other less frequent bacterial species found included Pseudomonas aeruginosa, Streptococus spp. and Proteus spp. Infection was negatively associated with the healing status of wounds.

Healthcare professionals were especially vulnerable to pandemic, both to become infected and to develop a psychological problem. The aim of this systematic review is to analyze the effectiveness of psychological interventions for healthcare professionals in reducing the experienced psychological impact. From the 405 identified studies, 10 were included in this review. Four databases were searched and the risk of bias of included studies was assessed. The studies considered were randomized controlled trials. The screening and selection process was conducted by two independent reviewers. All studies presented results related with depression, anxiety, and stress during pandemic. Six were delivered using new technologies. The most effective were two psychological interventions with frequent contact and feedback provided by a mental health professional. The psychological interventions compared with non‐intervention groups presented more significant results than those compared with another intervention. The highlights of this systematic review were the urgency of designing effectiveness psychological interventions for healthcare professionals to reduce the emotional burden associate with this job. These interventions should be maintained over the time, supported by a professional and provided from the workplace. These proposals presented promising results but were more psychological resources than psychological interventions.

Background: the study of body dissatisfaction has been focused on their perceptual and cognitive-behavioral components, being the affective component the least analyzed, both in Spain and Chile. Until now, it has been observed more presence of body dissatisfaction in overweight women. This fact has been related with the thinness beauty ideal established by society. Objective: to compare the different components of body dissatisfaction (perceptual, cognitive-behavioral and affective) in adults in a community sample of both sexes of Spain and Chile. Method: the sample consisted of 390 participants and has been divided in two samples by country (n = 179 Chileans; n = 211 Spanish). At the same time, these groups were divided in two groups by body mass index (BMI) and also by sex. The different components of body dissatisfaction were evaluated using specific questionnaires for each of them. Results and conclusion: both in Spain and in Chile, people with overweight show more dissatisfaction in the perceptual and affective areas, especially women. However, cognitive-behavioral component is the only one where differences between countries were found, showing overweight Spanish women more dissatisfaction. These results verify a higher presence of body dissatisfaction in women with overweight (t = 4.14, p < 0.001, d = 0.72, IC = 0.22-1.12), related to the greater pressure on appearance in the female population.

Background: Web-based delivered interventions have become an innovative option to treat health problems, like obesity. The aim of this systematic review and network meta-analysis was to analyze the effectiveness of web-based behavioral treatments for adults with overweight and obesity. Web-based interventions and comparison interventions (traditional weight control programs) were classified according to the following feedback characteristics: frequency, personalization, and provider (human versus machine). Method: From the initial 1789 studies, 15 were included in this review. A network meta-analysis was conducted to analyze the efficacy of web-based programs with traditional interventions, considering direct and indirect comparisons. The main outcome was the weight loss mean difference (kg) between baseline and post-treatment. Heterogeneity and consistency assumptions were validated to conduct the network meta-analysis. Results: Network meta-analysis showed comparisons between different treatment options. The main results were that Intensive Contact Web-based programs were more effective than wait-list (Mean Difference − 1.86 kg; 95% Confidence Interval: − 3.61, − 0.12). Moreover, Intensive Contact Web-based programs were more effective than the other web-based options and self-help traditional interventions. However, the only significant comparison was Intensive Contact Web-based programs versus Guided Self-Help Web-based programs (Mean Difference − 4.31 kg; 95% Confidence Interval: − 5,22, − 3,41). Intensive Contact Web-based programs were the most effective treatment option according the obtained results, achieving the first place in the ranking provided by the network meta-analysis with 98.5% of probabilities. Conclusions: Intensive Contact Web-based interventions have obtained the first position in the ranking, proving the relevance of frequent, personalized, and professional feedback and their association with a better prognosis for people with overweight and obesity. These results provide relevant information to design more effective treatments for people with overweight and obesity, in a new format especially appropriate for the current situation.
