Abstract We use complex systems science to explore the emergent behavioral patterns that typify eusocial species, using collective ant foraging as a paradigmatic example. Our particular aim is to provide a methodology to quantify how the collective orchestration of foraging provides functional advantages to ant colonies. For this, we combine (i) a purpose-built experimental arena replicating ant foraging across realistic spatial and temporal scales, and (ii) a set of analytical tools, grounded in information theory and spin-glass approaches, to explore the resulting data. This combined approach yields computational replicas of the colonies; these are high-dimensional models that store the experimental foraging patterns through a training process, and are then able to generate statistically similar patterns, in an analogous way to machine learning tools. These in silico models are then used to explore the colony performance under different resource availability scenarios. Our findings highlight how replicas of the colonies trained under constant and predictable experimental food conditions exhibit heightened foraging efficiencies, manifested in reduced times for food discovery and gathering, and accelerated transmission of information under similar conditions. However, these same replicas demonstrate a lack of resilience when faced with new foraging conditions. Conversely, replicas of colonies trained under fluctuating and uncertain food conditions reveal lower efficiencies at specific environments but increased resilience to shifts in food location.

La diagramación de preguntas y respuestas originadas durante la dinámica se procesó mediante un análisis temático, y el resultado nos permitió identificar al juego como una herramienta para construir un espacio donde estas habilidades de conciencia de futuros se pueden potencializar, desde sus valores comunitarios.

In Ecuador, about 95.9% of dwellings are built with masonry, however the local production of bricks does not meet technical standards and there is no scientific research on its geometric characterization and the technical state of their production. The geometric characterization of bricks is essential for the standardization of materials and constructions and allows the design of structures with a higher degree of accuracy. This research, conducted in 12 provinces of the 3 continental regions of the country, where 79% of the buildings are concentrated, studies for the first time the geometric characteristics of solid clay bricks in Ecuador. The results show that 67% of the brick production in Ecuador is artisanal and 98% of the factories do not comply with the technical standards for brick production. The authors present the characteristic dimensions of solid bricks produced in different regions of Ecuador. The results show a high variation in brick dimensions depending on the region, and even in a same province the dimensions depend on the factory, since its production does not comply with any standard. Ecuadorian standards regulating brick geometry need to be updated taking into account the real characteristics of the national brick production.

El territorio de la República del Ecuador presenta una alta sismicidad. En Ecuador el 95.9% de estructuras de vivienda son construidas con el uso de mamposterías. Se observa que entre los profesionales de la construcción en Ecuador existe un desconocimiento generalizado sobre las propiedades de los materiales constitutivos de las mamposterías y las normas para su diseño estructural. Tal desconocimiento ha generado la proliferación de construcciones que no cumplen con estándares técnicos de sismorresistencia y seguridad estructural, lo que puede generar considerables pérdidas económicas y sobre todo poner en riesgo la integridad física de las personas. El objetivo de esta investigación es determinar de manera cuantitativa la realidad local sobre el conocimiento técnico y uso de mamposterías en Ecuador. Los resultados evidencian principalmente que, el 82% de profesionales de la construcción son profesionales jóvenes; el 33.8% no supera los 30 años de edad; el 51.2% posee una experiencia profesional menor a 5 años; el 71% nunca o casi nunca realiza el diseño estructural incluyendo las mamposterías como elementos del sistema estructural; el 81% nunca recibió contenidos académicos sobre diseño estructural de mamposterías durante sus estudios superiores en Ecuador; existe un desconocimiento generalizado sobre las propiedades mecánicas de los materiales para mamposterías y la norma ecuatoriana para el diseño de mampostería estructural presenta importantes falencias. Abstract The territory of the Republic of Ecuador has a high seismicity. In Ecuador, 95.9% of housing structures are built with the use of masonry. It is observed that among construction professionals in Ecuador there is a general lack of knowledge about the properties of the constituent materials of masonry and the standards for their structural design. This lack of knowledge has led to the proliferation of constructions that do not comply with technical standards of seismic resistance and structural safety, which can generate considerable economic losses and, above all, put the physical integrity of people at risk. The objective of this research is to quantitatively determine the local reality of the technical knowledge and use of masonry in Ecuador. The results show that 82% of construction professionals are young professionals; 33.8% are under 30 years of age; 51.2% have less than 5 years of professional experience; 71% never or almost never carry out structural design including masonry as elements of the structural system; 81% never received academic content on structural design of masonry during their higher education in Ecuador; there is a general lack of knowledge about the mechanical properties of masonry materials and the Ecuadorian standard for the design of structural masonry has significant shortcomings.

The Itaipu Binational dam is a giant hydroelectric project situated on the Parana River, which began its construction in 1973 and was completed in 1983. It was undertaken by Brazil and Paraguay, two countries with enormous geopolitical and economic differences. With 14,000 MWh of installed power, it is the second largest hydroelectric dam in the world. Both countries are partners in this project, but the socioeconomic results have not been as expected. In this regard, although Paraguay’s GDP per capita, between 1983 and 2020, increased by 341%, Itaipu did not represent a true economic development engine for Paraguay. On the other hand, it had serious negative impacts especially on social, demographic, and environmental aspects. A structural equations model (SEM) was designed, in its Path Analysis modality, which includes 10 variables: 3 exogenous (Royalties from Itaipu, Electric power exports, and External debt) and 7 endogenous (GDP per capita, Proportion of agricultural sector in GDP, Proportion of service sector in GDP, Population with needs unsatisfied, Housing deficit, Changes of land use, and CO2 emissions). The model exposes an adequate simulation range, and the results show a high degree of goodness of fit, using different indices (CMIN, FMIN, CFI, and RMSEA). The corresponding tests upon the model validate the hypotheses raised. JEL Classification: O13, O54, H54, H60, F34, C18

Background Higher social support protects people from developing mental disorders. Limited evidence is available on the mechanism through which social support plays this protective role.Objective To investigate the stress-buffering process of social support on depressive symptoms using a novel longitudinal dynamic symptom network approach.Methods A total of 4242 adult participants who completed the first two waves (from May to October 2020) of the International Covid Mental Health Survey were included in the study. Cross-lagged panel network modelling was used to estimate a longitudinal network of self-reported social support, loneliness and depressive symptoms. Standardised regression coefficients from regularised cross-lagged regressions were estimated as edge weights of the network.Findings The results support a unidirectional protective effect of social support on key depressive symptoms, partly mediated through loneliness: A higher number of close confidants and accessible practical help was associated with decreased anhedonia (weight=−0.033) and negative self-appraisal symptoms (weight=−0.038). Support from others was also negatively associated with loneliness, which in turn associated with decreased depressed mood (weight=0.086) and negative self-appraisal (weight=0.077). We identified a greater number of direct relationships from social support to depressive symptoms among men compared with women. Also, the edge weights from social support to depression were generally stronger in the men’s network.Conclusions Reductions in negative self-appraisal might function as a bridge between social support and other depressive symptoms, and, thus, it may have amplified the protective effect of social support. Men appear to benefit more from social support than women.Clinical implications Building community-based support networks to deliver practical support, and loneliness reduction components are critical for depression prevention interventions after stressful experiences.

Abstract Background The World Health Organization has formally recognized that healthcare professionals are at risk of developing mental health problems; finding ways to reduce their stress is mandatory to improve both their quality of life and, indirectly, their job performance. In recent years, particularly since the COVID-19 pandemic outbreak, there has been a proliferation of online interventions with promising results. The purpose of the present study is twofold: to test the effectiveness of an online, self-guided intervention, MINDxYOU, to reduce the stress levels of healthcare workers; and to conduct an implementation study of this intervention. Additionally, an economic evaluation of the intervention will be conducted. Methods The current study has a hybrid effectiveness-implementation type 2 design. A stepped wedge cluster randomized trial design will be used, with a cohort of 180 healthcare workers recruited in two Spanish provinces (Malaga and Zaragoza). The recruitment stage will commence in October 2022. Frontline health workers who provide direct care to people in a hospital, primary care center, or nursing home setting in both regions will participate. The effectiveness of the intervention will be studied, with perceived stress as the main outcome (Perceived Stress Scale), while other psychopathological symptoms and process variables (e.g., mindfulness, compassion, resilience, and psychological flexibility) will be also assessed as secondary outcomes. The implementation study will include analysis of feasibility, acceptability, adoption, appropriateness, fidelity, penetration, and sustainability. The incremental costs and benefits, in terms of quality-adjusted life years, will be examined by means of cost-utility and cost-effectiveness analyses. Discussion MINDxYOU is designed to reduce healthcare workers’ stress levels through the practice of mindfulness, acceptance, and compassion, with a special focus on how to apply these skills to healthy habits and considering the particular stressors that these professionals face on a daily basis. The present study will show how implementation studies are useful for establishing the framework in which to address barriers to and promote facilitators for acceptability, appropriateness, adoption, feasibility, fidelity, penetration, and sustainability of online interventions. The ultimate goal is to reduce the research-to-practice gap. Trial registration This study was registered in ClinicalTrials.gov on 29/06/2022; registration number: NCT05436717.

This study aimed to investigate the temporal pattern of goal scoring in recent 8 editions of the elite Brazilian Championship. The sample consisted of 3,039 matches (7,170 goals) from the seasons 2012 to 2019 of the 1st division of the Brazilian Championship. The official match reports, which are publicly available on the website of the Brazilian Football Confederation - CBF (www.cbf.com.br), were analyzed. Data collection occurred through the observational methodology. Two experienced observers registered the data. Inter and intra-rater reliability was calculated to guarantee the quality of the observation system. During the 2012-2019 seasons an average of 393.50 goals occurred in the 1st half, and 502.75 in the 2nd half. The average number of goals per match was 2.36. Results indicated a higher incidence of goals scored in the 2nd half of the match (p < 0.05). An upward trend in the number of goals scored was observed as match-play time progressed. Football coaches and practitioners may plan and practice match strategies more effectively according to the time trend of goals in a match.

The death of a loved one has physical, psychological, and social consequences. Between 9.8 and 21.5 % of people who lose a loved one develop Prolonged Grief Disorder (PGD). Internet- and computer-based interventions (i.e., Internet-delivered Cognitive-Behavioral Therapy, iCBT) are cost-effective and scalable alternatives that make it possible to reach more people with PGD. The main goal of the present investigation was to examine the effect and feasibility (usability and satisfaction) of an iCBT (GROw program) for adults with PGD. A secondary objective was to detect adherence to the app (Emotional Monitor) used to measure daily grief symptoms. The study had a single-case multiple-baseline AB design with six participants. The GROw program is organized sequentially in eight modules, and it is based on the dual-process model of coping with bereavement. Evaluations included a pre-to-post treatment assessment of depression, grief symptoms, and typical grief beliefs, along with daily measures of symptom frequency and intensity on the Emotional Monitor App. Treatment opinions and adherence to the App were also collected. Efficacy data were calculated using a Nonoverlap of All Pairs (NAP) analysis and Reliable Change Index (RCI). The mean age of the sample was 29.5 years (SD = 8.19). Two participants dropped out of the study. Adherence to the App varied across patients (4.8 % -77.8 %). Most participants (75 %) showed a clinically significant change (recovered) in depression, and 50 % obtained a clinically significant improvement (recovered) in symptoms of loss and typical beliefs in complicated grief. The participants reported high usability and satisfaction with the treatment content and format. In sum, the GROw program was very well accepted and generally feasible, and it has strong potential for treating PGD. The results support scaling up the treatment by using more complex designs with larger samples (i.e., randomized controlled trials comparing GROw with active conditions).

This study focuses on the modeling and control optimization of the pitch–roll angles orientation in a quad-rotor UAV (unmanned aerial vehicle) drone system. To address the control challenge, PID (proportional–integral–derivative) controllers are used, which have been tuned through a model-based optimization approach. A non-linear model of the system is obtained and further validated experimentally. The model is implemented in Simulink to conduct model-based optimization. The controller design uses an IMC (internal model control) model-based approach to establish the initial parameters for a PID controller. In the subsequent design phase, a multiobjective approach is taken, incorporating weighted cost functions that account for IAE (integral absolute error) and ITAE (integral of time-weighted absolute error) forms, along with battery usage. The outcomes of this design are showcased through simulations and real-world platform testing.

Abstract COVID-19 is spreading rapidly in Brazil, a country of continental dimensions, but the incidence of the disease is showing to be very heterogeneous, affecting cities and regions differently. Thus, there is a gap regarding what factors would contribute to accentuate the differences in the incidence of COVID-19 among Brazilian cities. This work aimed to evaluate the effect of altitude on the incidence of COVID-19 in Brazilian cities. We analyzed the relative incidence (RI), the relative death rate (RDR) of COVID-19, and air relative humidity (RH) in all 154 cities in Brazil with a population above 200 thousand inhabitants, located between 5 and 1135 m in altitude. Pearson's correlation analysis was performed to compare a relationship between altitude with RI and RDR, and between RH with RI and RDR. Altitudes were classified into three classes [low (altitude ≤ 97 m a. s. l), middle (97

Background: More research is needed in the field of Internet-delivered Cognitive Behavioral Treatments (ICBTs) for specific phobia in order to understand which characteristics are important in online exposure scenarios. The aim of the present work was to conduct a feasibility pilot study to explore participants' opinions, preferences, and acceptability ratings of two types of images (still images vs 360° navigable images) in an ICBT for Flying Phobia (FP). A secondary aim was to test the potential effectiveness of the two active treatment arms compared to a waiting list control group. An exploratory aim was to compare the role of navigable images vs. still images in the level of sense of presence and reality judgment and explore their possible mediation in treatment effectiveness. Methods: Participants were randomly allocated to three conditions: NO-FEAR Airlines with still images (n = 26), NO-FEAR Airlines with still and navigable images (n = 26), and a waiting list group (n = 26). Primary outcome measures were participants' opinions, preferences, satisfaction, and acceptance regarding the images used in the exposure scenarios. Secondary outcome measures included FP symptomatology outcomes and measures of sense of presence and reality judgment. Results: Participants in the study preferred navigable images over still images before and after treatment (over 84%), and they considered them more effective and logical for the treatment of their problem. However, adherence in the experimental conditions was low (42.3% dropout rate), and more participants withdrew from the group that included navigable images compared to the group that only included still images (14 vs. 8), with no statistical differences in attrition between the two conditions. NO-FEAR Airlines proved to be effective in reducing FP symptomatology compared to the control group, with large between-group effect sizes on all FP measures (ranging from 0.76 to 2.79). No significant mediation effect was found for sense of presence or reality judgment in treatment effectiveness. Discussion: The results of the current study suggest that participants prefer more immersive images in exposure scenarios, providing data that can help to design useful exposure scenarios to treat specific phobias in the future. They also provide evidence supporting the effectiveness of an ICBT for FP. Trial registration: Registered at Clinicaltrials.gov (NCT03900559) on April 9, 2019. Retrospectively registered.

Abstract In this article, we use the notion of legitimacy to analyse shifts in global humanitarian interventions since the 1990s, culminating in the contested adoption of the Responsibility to Protect (R2P) framework under the United Nationsumbrella in 2005. We assess how this important shift was disputed with narratives of protection and interference, and argue that the engagement of nonhegemonic actors (specifically Brazil and Russia) with the scope of humanitarian protection has influenced the substantive legitimacy of this global governance issue over the past three decades by creating a norm-making process in which the fundamental features of humanitarianism have been tested and challenged.

Esta pesquisa teve como objetivo investigar relações entre o reconhecimento de personagens infantis e a associação de logos e marcas de produtos de tabaco, fast-food, refrigerantes e bebidas alcoólicas em 90 crianças, entre 4-9 anos, da cidade do Rio de Janeiro, sendo a maioria do sexo masculino (56,7%). A escolha da faixa etária se baseou no modelo de comportamento consumidor proposto por McNeal, o qual diz que o consumidor se encontra plenamente formado aos 8 anos de idade.

As pontuações globais para reconhecimento de logos correlacionaram-se significativamente com as pontuações globais para reconhecimento de personagens infantis (r = 0.38, p

BackgroundChronic medical illnesses significantly and negatively affect the quality of life of individuals who suffer them and represent one of the most important challenges faced by healthcare providers and policy-makers due to its rising prevalence and high rates of comorbidity. Compassion-based interventions delivered over the Internet may be a useful approach to facilitate illness management and improve the quality of life of individuals with chronic medical conditions.ObjectivesThe purpose of this study is to describe a protocol for a randomized controlled trial to test the efficacy of the Internet Attachment-Based Compassion Therapy (iABCT) to improve the quality of life and well-being of patients with chronic medical illnesses.MethodA two-arm, parallel-group, randomized controlled trial (RCT) will be carried out, with three assessment points (baseline, 3-month, and 6-month) under two conditions: intervention group and control group (waiting list). The primary outcomes include the quality of life on the EuroQol 5-Dimensions Questionnaire (EQ-5D) and the Pemberton Happiness Index (PHI). Secondary outcomes, such as compassion, self-care behaviors, illness interference, self-criticism, symptomatology, attachment styles, social support, and illness perception, will be considered. Moreover, an assessment on satisfaction and usability will be carried out. A total of 68 participants as minimum will be recruited (34 per arm). Intent-to-treat mixed-model analyses without any ad hoc imputations will be conducted.ConclusionsFindings of this study will provide new insights into the potential of self-applied compassion-based interventions (CBI) delivered online in the context of chronic medical illnesses, considering aspects of their implementation (e.g., facilitators, barriers) and mechanisms of change.Trial registrationThe study is registered under Clinicaltrials.gov (NCT04809610) and it is currently in the participant recruitment phase.

High-salt (HS) diets have recently been linked to oxidative stress in the brain, a fact that may be a precursor to behavioral changes, such as those involving anxiety-like behavior. However, to the best of our knowledge, no study has evaluated the amygdala redox status after consuming a HS diet in the pre- or postweaning periods. This study aimed to evaluate the amygdala redox status and anxiety-like behaviors in adulthood, after inclusion of HS diet in two periods: preconception, gestation, and lactation (preweaning); and only after weaning (postweaning). Initially, 18 females and 9 male Wistar rats received a standard (n = 9 females and 4 males) or a HS diet (n = 9 females and 5 males) for 120 days. After mating, females continued to receive the aforementioned diets during gestation and lactation. Weaning occurred at 21-day-old Wistar rats and the male offspring were subdivided: control-control (C-C)—offspring of standard diet fed dams who received a standard diet after weaning (n = 9–11), control-HS (C-HS)—offspring of standard diet fed dams who received a HS diet after weaning (n = 9–11), HS-C—offspring of HS diet fed dams who received a standard diet after weaning (n = 9–11), and HS-HS—offspring of HS diet fed dams who received a HS diet after weaning (n = 9–11). At adulthood, the male offspring performed the elevated plus maze and open field tests. At 152-day-old Wistar rats, the offspring were euthanized and the amygdala was removed for redox state analysis. The HS-HS group showed higher locomotion and rearing frequency in the open field test. These results indicate that this group developed hyperactivity. The C-HS group had a higher ratio of entries and time spent in the open arms of the elevated plus maze test in addition to a higher head-dipping frequency. These results suggest less anxiety-like behaviors. In the analysis of the redox state, less activity of antioxidant enzymes and higher levels of the thiobarbituric acid reactive substances (TBARS) in the amygdala were shown in the amygdala of animals that received a high-salt diet regardless of the period (pre- or postweaning). In conclusion, the high-salt diet promoted hyperactivity when administered in the pre- and postweaning periods. In animals that received only in the postweaning period, the addition of salt induced a reduction in anxiety-like behaviors. Also, regardless of the period, salt provided amygdala oxidative stress, which may be linked to the observed behaviors.

Gambling Disorder is a prevalent non-substance use disorder, which contrasts with the low number of people requesting treatment. Information and Communication Technologies (ICT) could help to enhance the dissemination of evidence-based treatments and considerably reduce the costs. The current study seeks to assess the efficacy of an online psychological intervention for people suffering from gambling problems in Spain. The proposed study will be a two-arm, parallel-group, randomized controlled trial. A total of 134 participants (problem and pathological gamblers) will be randomly allocated to a waiting list control group (N = 67) or an intervention group (N = 67). The intervention program includes 8 modules, and it is based on motivational interviewing, cognitive-behavioral therapy (CBT), and extensions and innovations of CBT. It includes several complementary tools that are present throughout the entire intervention. Therapeutic support will be provided once a week through a phone call with a maximum length of 10 min. The primary outcome measure will be gambling severity and gambling-related cognitions, and secondary outcome measures will be readiness to change, and gambling self-efficacy. Other variables that will be considered are depression and anxiety symptoms, positive and negative affect, difficulties in emotion regulation strategies, impulsivity, and quality of life. Individuals will be assessed at baseline, post-treatment, and 3-, 6-, and 12-month follow-ups. During the treatment, participants will also respond to a daily Ecological Momentary Intervention (EMI) in order to evaluate urges to gamble, self-efficacy to cope with gambling urges, gambling urge frequency, and whether gambling behaviour occurs. The EMI includes immediate automatic feedback depending on the participant's responses. Treatment acceptance and satisfaction will also be assessed. The data will be analysed both per protocol and by Intention-to-treat. As far as we know, this is the first randomized controlled trial of an online psychological intervention for gambling disorder in Spain. It will expand our knowledge about treatments delivered via the Internet and contribute to improving treatment dissemination, reaching people suffering from this problem who otherwise would not receive help.

While approaches based on physical grounds (such as the drift-diffusion model—DDM) have been exhaustively used in psychology and neuroscience to describe perceptual decision making in humans, similar approaches to complex situations, such as sequential (tree-like) decisions, are still scarce. For such scenarios that involve a reflective prospection of future options, we offer a plausible mechanism based on the idea that subjects can carry out an internal computation of the uncertainty about the different options available, which is computed through the corresponding Shannon entropy. When the amount of information gathered through sensory evidence is enough to reach a given threshold in the entropy, this will trigger the decision. Experimental evidence in favor of this entropy-based mechanism was provided by exploring human performance during navigation through a maze on a computer screen monitored with the help of eye trackers. In particular, our analysis allows us to prove that (i) prospection is effectively used by humans during such navigation tasks, and an indirect quantification of the level of prospection used is attainable; in addition, (ii) the distribution of decision times during the task exhibits power-law tails, a feature that our entropy-based mechanism is able to explain, unlike traditional (DDM-like) frameworks.

Lucid dreaming, a specific phenomenon of dream consciousness, refers to the experience being aware that one is dreaming. The primary aim of this research was to validate a Spanish version of the Lucidity and Consciousness in Dreams scale (LuCiD). A secondary aim was to explore whether meditation experience and mindfulness trait were related to LuCiD scores. Data from 367 Spanish men (34.6%) and women (65.4%) who completed LuCiD, the Five Facets of Mindfulness Questionnaire (FFMQ), and the Positive and Negative Affect Schedule (PANAS) were examined. From the total sample, 40.3% indicated some experience with formal meditation (meditators), while 59.7% did not have any meditation experience (non-meditators). A random subsample of 101 participants, who completed LuCiD for a second time after a period of 10–15days, was used for test–retest reliability analysis. The LuCiD scale comprises 28 items distributed across eight factors: insight, control, thought, realism, memory, dissociation, negative emotion, and positive emotion. Factor structure, reliability by both internal consistency and test–retest reliability, and construct and concurrent validity were tested. Confirmatory factor analysis (CFA) confirmed the original eight-factor model, showing goodness of fit in contrast to a single-factor model. Item 15 was deleted from the Dissociation factor as it performed poorly (i.e., skewness and kurtosis, non-normal distribution of responses, and corrected item–total correlation under 0.40). The scale showed adequate values of internal consistency (between α=0.65 for Memory and α=0.83 for Positive Emotion) and test–retest reliability by significant Pearson correlations (p

Introduction Grief is an emotional reaction to the loss of a loved one with a natural recovery. Approximately 10% of people who lose a loved one develop prolonged grief disorder (PGD). Internet-based and computer-based interventions (ie, internet-delivered cognitive–behavioural therapy, iCBT) are a cost-effective alternative that makes it possible to reach more people with PGD. The main aim of this study is to assess the feasibility of a new iCBT—called GROw—for PGD. As a secondary objective, the potential effectiveness of GROw will be explored.Methods and analysis This study is a two-arm feasibility randomised trial. A total of 48 adults with PGD who meet the eligibility criteria will be randomised to the experimental group (iCBT: GROw) or the active control group (face-to-face CBT treatment). The treatment is organised sequentially in eight modules in the iCBT format and 8–10 sessions in the face-to-face format, and both formats have the same therapeutic components. There will be five assessment points with qualitative and quantitative evaluations: screening, baseline, after the intervention, 3-month follow-up and 12-month follow-up. Consistent with the objectives, the measures are related to the feasibility outcomes for the main aim of the study (participant adherence, expectations and satisfaction with the treatment, preferences, alliance and utility) and psychological and mental health outcomes for secondary analyses (symptoms of grief, symptoms of depression, symptoms of anxiety, affectivity, quality of life, work and social adaptation, post-traumatic growth, purpose in life, mindfulness and compassion).Ethics and dissemination The Ethics Committee of the Universitat Jaume I (Castellón, Spain) granted approval for the study (CD/002/2019). Dissemination will include publications and presentations at national and international conferences.Trial registration number NCT04462146.

Abstract Background Depressive symptoms are quite prevalent in Primary Care (PC) settings. The treatment as usual (TAU) in PC is pharmacotherapy, despite the high relapse rates it produces. Many patients would prefer psychotherapy, but specialized services are overloaded. Studies that apply Mindfulness-Based Interventions (MBIs) for the treatment of depression have obtained significant improvements. Brief low-intensity approaches delivered from PC could be a promising approach. This study aims to compare a low-intensity mindfulness intervention for the treatment of depression in PC using different intervention formats – a face-to-face MBI delivered in a group and the same MBI individually applied on the Internet – to a control group that will receive PC medical treatment as usual. Methods A randomized controlled clinical trial will be conducted in PC, with about 120 depressed patients allocated (1:1:1) to three groups: “face-to-face MBI + TAU”, “Internet-delivered MBI + TAU”, and “TAU alone”. The MBI programs will be composed of four modules. The primary outcome will be depressive symptoms, measured through the Beck Depression Inventory, assessed at pre- and post-treatment and 6- and 12-month follow-ups. Other outcomes will be mindfulness, happiness, affectivity, quality of life, and the use of healthcare services. Intention-to-treat analysis using linear mixed models adjusted for baseline scores and routine sociodemographic analysis that could show baseline differences will be conducted. Per-protocol secondary outcome analyses will also be performed. Discussion This is the first Spanish RCT to apply a low-intensity face-to-face MBI (plus TAU) to treat depression in PC settings compared to TAU (alone). Moreover, this study will also make it possible to evaluate the same MBI program (plus TAU), but Internet-delivered, considering their cost-effectiveness. Positive results from this RCT might have an important impact on mental health settings, helping to decrease the overload of the system and offering treatment alternatives beyond antidepressant medication through high-quality, flexible PC interventions.

Abstract Background There are evidence-based interventions for depression that include different components. However, the efficacy of their therapeutic components is unknown. Another important issue related to depression interventions is that, up to now, their therapeutic components have only focused on reducing negative symptoms rather than on improving positive affect and well-being. Because the low levels of positive affect are more strongly linked to depression than to other emotional disorders, it is important to include this variable as an important treatment target. Positive psychotherapeutic strategies (PPs) could help in this issue. The results obtained so far are consistent and promising, showing that Internet-based interventions are effective in treating depression. However, most of them are also multi-component, and it is important to make progress in investigating what each component contributes to the intervention. Methods The current study will be a three-armed, simple-blinded, randomized controlled clinical trial with a dismantling design. 192 participants will be randomly assigned to: a) an Internet-based Global Protocol condition, which includes traditional therapeutic components of evidence-based treatments for depression (Motivation for change, Psychoeducation, Cognitive Therapy, Behavioral Activation (BA), Relapse Prevention) and PPs component, offering strategies to enhance positive mood and promote psychological strengths; b) an Internet-based BA Protocol condition (without the PPs component), and c) an Internet-based PPs Protocol condition (without the BA component). Primary outcome measures will be the BDI-II and PANAS. Secondary outcomes will include other variables such as depression, anxiety and stress, quality of life, resilience, and wellbeing related measures. Treatment acceptance and usability will also be measured. Participants will be assessed at pre-, post-treatment, 3-, 6- and 12- month follow- ups. The data will be analyzed based on the Intention-to-treat principle. Per protocol analyses will also be performed. Discussion To the best of our knowledge, this is the first randomized dismantling intervention study for depression with the aim of exploring the contribution of a PPs component and the BA component in an Internet-based intervention. The three protocols are online interventions, helping to reach many people who need psychological treatments and otherwise would not have access to them.

Abstract Background Internet-based treatments appear to be a promising way to enhance the in vivo exposure approach, specifically in terms of acceptability and access to treatment. However, the literature on specific phobias is scarce, and, as far as we know, there are no studies on Flying Phobia (FP). This study aims to investigate the effectiveness of an Internet-based exposure treatment for FP (NO-FEAR Airlines) that includes exposure scenarios composed of images and sounds, versus a waiting-list control group. A secondary aim is to explore two ways of delivering NO-FEAR Airlines, with and without therapist guidance. Methods A randomized controlled trial (RCT) was conducted in which 69 participants were allocated to: 1) NO-FEAR Airlines totally self-applied, 2) NO-FEAR Airlines with therapist guidance, 3) a waiting-list control group. Primary outcome measures were the Fear of Flying Questionnaire-II and the Fear of Flying Scale. Secondary outcomes included the Fear and Avoidance Scales, Clinician Severity Scale, and Patient’s Improvement scale. Behavioral outcomes (post-treatment flights and safety behaviors) were also included. Mixed-model analyses with no ad hoc imputations were conducted for primary and secondary outcome measures. Results NO-FEAR Airlines (with and without therapist guidance) was significantly effective, compared to the waiting list control group, on all primary and secondary outcomes (all ps

This article compares two contrasting models of Public Policies in the Fight against Poverty within the framework of the TENONDERÁ Program of the Secretariat of Social Action - SAS and within the framework of the “Sembrando Oportunidades”, Program of the Technical Planning Secretariat - STP. It wants to contribute to illuminate the debate of what would be the model of intervention adapted to the Paraguayan reality to develop social changes in the process of institutional intervention of more efficient and effective public policies against poverty. The study presented finds better results within the framework of a model that incorporates the social dimension and the concept of poverty as exclusion.

Background: Flying Phobia (FP) is a prevalent disorder that can cause serious interference in a person's life. ICBT interventions have already shown their efficacy in several studies, but studies in the field of specific phobias are still scarce. Moreover, few studies have investigated the feasibility of using different types of images in exposure scenarios in ICBTs and no studies have been carried out on the role of sense of presence and reality judgement. The aim of the present study is to explore the feasibility of an ICBT for FP (NO-FEAR Airlines) using two types of images with different levels of immersion (still and navigable images). A secondary aim is to explore the potential effectiveness of the two experimental conditions using two types of images compared to a waiting list control group. Finally, the role of navigable images compared to the still images in the level of anxiety, sense of presence, and reality judgement will also be explored. This paper presents the study protocol. Methods: This study is a three-armed feasibility pilot study with the following conditions: NO-FEAR Airlines with navigable images, NO-FEAR Airlines with still images, and a waiting list group. A minimum of 60 participants will be recruited. The intervention will have a maximum duration of 6 weeks. Measurements will be taken at four different moments: baseline, post-intervention, and two follow-ups (3- and 12-month). Participants' opinions, preference, satisfaction and acceptance regarding the images used in the exposure scenarios will be assessed. FP symptomatology outcomes will also be considered for secondary analyses. The anxiety, sense of presence, and reality judgement in the exposure scenarios will also be analysed. Discussion: This study will conduct a pilot study on the feasibility of an ICBT for FP and it is the first one to explore the evaluation of patients of the two type of images (still and navigable) and the role of presence and reality judgement in exposure scenarios delivered through the Internet. Research in this field can have an impact on the way these scenarios are designed and developed, as well as helping to explore whether they have any effect on adherence.

Background: Police officers' high-stress levels and its deleterious consequences are raising awareness to an epidemic of mental health problems and quality of life (QoL) impairment. There is a growing evidence that mindfulness-based interventions are efficacious to promote mental health and well-being among high-stress occupations.Methods: The POLICE study is a multicenter randomized controlled trial (RCT) with three assessment points (baseline, post-intervention, and 6-month follow-up) where police officers were randomized to mindfulness-based health promotion (MBHP) (n = 88) or a waiting list (n = 82). This article focuses on QoL, depression and anxiety symptoms, and religiosity outcomes. Mechanisms of change and MBHP feasibility were evaluated.Results: Significant group × time interaction was found for QoL, depression and anxiety symptoms, and non-organizational religiosity. Between-group analysis showed that MBHP group exhibited greater improvements in QoL, and depression and anxiety symptoms at both post-intervention (QoL d = 0.69 to 1.01; depression d = 0.97; anxiety d = 0.73) and 6-month follow-up (QoL d = 0.41 to 0.74; depression d = 0.60; anxiety d = 0.51), in addition to increasing non-organizational religiosity at post-intervention (d = 0.31). Changes on self-compassion mediated the relationship between group and pre-to-post changes for all QoL domains and facets. Group effect on QoL overall health facet at post-intervention was moderated by mindfulness trait and spirituality changes.Conclusion: MBHP is feasible and efficacious to improve QoL, and depression and anxiety symptoms among Brazilian officers. Results were maintained after 6 months. MBHP increased non-organizational religiosity, although the effect was not sustained 6 months later. To our knowledge, this is the first mindfulness-based intervention RCT to empirically demonstrate these effects among police officers. Self-compassion, mindfulness trait, and spirituality mechanisms of change are examined.Clinical Trial Registration:www.ClinicalTrials.gov. identifier: NCT03114605.

Emergence of collective, as well as superorganism-like, behaviour in biological populations requires the existence of rules of communication, either direct or indirect, between organisms. Because reaching an understanding of such rules at the individual level can be often difficult, approaches carried out at higher, or effective, levels of description can represent a useful alternative. In the present work, we show how a spin-glass approach characteristic of statistical physics can be used as a tool to characterize the properties of the spatial occupancy patterns of a biological population. We exploit the presence of pairwise interactions in spin-glass models for detecting correlations between occupancies at different sites in the media. Such correlations, we claim, represent a proxy to the existence of planned and/or social strategies in the spatial organization of the population. Our spin-glass approach does not only identify those correlations but produces a statistical replica of the system (at the level of occupancy patterns) that can be subsequently used for testing alternative conditions/hypothesis. Here, this methodology is presented and illustrated for a particular case of study: we analyse occupancy patterns of Aphaenogaster senilis ants during foraging through a simplified environment consisting of a discrete (tree-like) artificial lattice. Our spin-glass approach consistently reproduces the experimental occupancy patterns across time, and besides, an intuitive biological interpretation of the parameters is attainable. Likewise, we prove that pairwise correlations are important for reproducing these dynamics by showing how a null model, where such correlations are neglected, would perform much worse; this provides a solid evidence to the existence of superorganism-like strategies in the colony.

Abstract Background Police officers experience a high degree of chronic stress. Policing ranks among the highest professions in terms of disease and accident rates. Mental health is particularly impacted, evidenced by elevated rates of burnout, anxiety and depression, and poorer quality of life than the general public. Mindfulness training has been shown to reduce stress, anxiety, burnout and promote quality of life in a variety of settings, although its efficacy in this context has yet to be systematically evaluated. Therefore, this trial will investigate the efficacy of a mindfulness-based intervention versus a waitlist control in improving quality of life and reducing negative mental health symptoms in police officers. Methods This multicenter randomized controlled trial has three assessment points: baseline, post-intervention, and six-month follow-up. Active police officers (n = 160) will be randomized to Mindfulness-Based Health Promotion (MBHP) or waitlist control group at two Brazilian major cities: Porto Alegre and São Paulo. The primary outcomes are burnout symptoms and quality of life. Consistent with the MBHP conceptual model, assessed secondary outcomes include perceived stress, anxiety and depression symptoms, and the potential mechanisms of resilience, mindfulness, decentering, self-compassion, spirituality, and religiosity. Discussion Findings from this study will inform and guide future research, practice, and policy regarding police offer health and quality of life in Brazil and globally.

Abstract Background Adjustment Disorder (AjD) is a common and disabling mental health problem. The lack of research on this disorder has led to the absence of evidence-based interventions for its treatment. Moreover, because the available data indicate that a high percentage of people with mental illness are not treated, it is necessary to develop new ways to provide psychological assistance. The present study describes a Randomized Controlled Trial (RCT) aimed at assessing the effectiveness and acceptance of a linear internet-delivered cognitive-behavioral therapy (ICBT) intervention for AjD. Methods A two-armed RCT was designed to compare an intervention group to a waiting list control group. Participants from the intervention group will receive TAO, an internet-based program for AjD composed of seven modules. TAO combines CBT and Positive Psychology strategies in order to provide patients with complete support, reducing their clinical symptoms and enhancing their capacity to overcome everyday adversity. Participants will also receive short weekly telephone support. Participants in the control group will be assessed before and after a seven-week waiting period, and then they will be offered the same intervention. Participants will be randomly assigned to one of the 2 groups. Measurements will be taken at five different moments: baseline, post-intervention, and three follow-up periods (3-, 6- and 12-month). BDI-II and BAI will be used as primary outcome measures. Secondary outcomes will be symptoms of AjD, posttraumatic growth, positive and negative affect, and quality of life. Discussion The development of ICBT programs like TAO responds to a need for evidence-based interventions that can reach most of the people who need them, reducing the burden and cost of mental disorders. More specifically, TAO targets AjD and will entail a step forward in the treatment of this prevalent but under-researched disorder. Finally, it should be noted that this is the first RCT focusing on an internet-based intervention for AjD in the Spanish population. Trial registration ClinicalTrial.gov: NCT02758418.

In this minireview we present the main results regarding the transport properties of stochastic movement with relocations to known positions. To do so, we formulate the problem in a general manner to see several cases extensively studied during the last years as particular situations within a framework of random walks with memory. We focus on (i) stochastic motion with resets to its initial position followed by a waiting period, and (ii) diffusive motion with memory-driven relocations to previously visited positions. For both of them we show how the overall transport regime may be actively modified by the details of the relocation mechanism.

La Escala de Afectos Positivos y Afectos Negativos (PANAS) es hoy uno de los instrumentos más utilizados en la investigación de estados afectivos, tanto en adultos como en niños. El presente estudio fue realizado con el objetivo de evaluar, desde el punto de vista psicométrico, una versión brasileña de esa escala en una muestra nacional. Además de las propiedades psicométricas, se evaluó la validez convergente del instrumento. En total, participaron de esta investigación 2648 estudiantes universitarios, matriculados en los cursos de Psicología e Ingeniería de una universidad privada, en 15 ciudades brasileñas respondiendo al cuestionario electrónico disponible en Internet. Los participantes respondieron a la Escala Analógica Visual de Bienestar Psicológico (FACES), la Escala de Felicidad Subjetiva (SHS) y la Escala Índice de Salud Mental (MHI-5). Los resultados de los análisis indican que el PANAS presenta propiedades psicométricas satisfactorias que autorizan su utilización en Brasil.

Research suggests that mindfulness can induce changes in the social domain, such as enhancing emotional connection to others, prosocial behavior, and empathy. However, despite growing interest in mindfulness in social psychology, very little is known about the effects of mindfulness on social cognition. Consequently, the aim of this study was to explore the relationship between mindfulness and social cognition by comparing meditators with non-meditators on several social cognition measures. A total of 60 participants (meditators, n = 30; non-meditators, n = 30) were matched on sex, age, and ethnic group, and then asked to complete the following assessment measures: Mindful Awareness Attention Scale (MAAS), Five Facet Mindfulness Questionnaire Short Form (FFMQ-SF), Interpersonal Reactivity Index (IRI), Revised Eyes Test, Hinting Task, Ambiguous Intentions and Hostility Questionnaire (AIHQ), Hospital Anxiety and Depression Scale (HADS), and Screening for Cognitive Impairment in Psychiatry (SCIP). The results showed that meditators reported higher empathy (except for the personal distress subscale), higher emotional recognition, higher theory of mind (ToM), and lower hostile attributional style/bias. The findings also demonstrated that dispositional mindfulness (both total score assessed with MAAS and mindfulness facets using the FFMQ) was associated with social cognition, although it was not equally correlated with all social cognition outcomes, and correlation patterns differ when analyses were conducted separately for meditators and non-meditators. In addition, results showed potential predictors for each social cognition variable, highlighting non-reactivity to inner experience as a key component of mindfulness in order to explain social cognition performance. In summary, the findings indicated that the meditator sample performed better on certain qualities (i.e., empathy, emotional recognition, ToM, hostile attributional style/bias) in comparison to non-meditators and, furthermore, support the notion that mindfulness is related to social cognition, which may have implications for the design of mindfulness-based approaches for use in clinical and non-clinical settings.

The study of social cognition (SC) has emerged as a key domain of mental health, supporting the notion that poorer performance in SC tasks is linked to psychopathology, although most studies have primarily addressed only schizophrenia (SZ). Some recent studies have also shown deficits of SC in obsessive-compulsive disorder (OCD) patients; however, little is known about how individuals with OCD may differ on SC performance from individuals with SZ. Moreover, initial research in this field suggests that mindfulness skills may be related to SC abilities such as theory of mind (ToM), emotion processing and empathy. Given the potential benefits of mindfulness for treating OCD and SZ, further efforts are needed to understand the association between mindfulness and SC in these populations. The main objective of this study was to compare samples of patients with SZ and OCD to healthy controls (HCs) on several social cognition (SC) domains and mindfulness measures. In total, 30 outpatients diagnosed with SZ, 31 outpatients diagnosed with OCD and 30 healthy controls were assessed in emotion recognition (the Eyes Test), ToM (the Hinting Task), attributional style (the Ambiguous Intentions and Hostility Questionnaire), empathy (the Interpersonal Reactivity Index) and dispositional mindfulness (the MAAS and the FFMQ). Both clinical groups showed poorer performance in emotion recognition and ToM than the HCs. The OCD and SZ patients did not significantly differ in impairment in SC, but the OCD group had higher scores in attributional style (intentionality and anger bias). With regard to mindfulness, the results found lower levels of acting with awareness for the HCs than for either clinical group and higher non-reactivity to inner experience for the HCs than for the individuals with OCD; the results also yielded significant correlations between SC and mindfulness. In conclusion, these findings revealed that SC abilities were impaired in the SZ and OCD groups compared to the HC group, suggesting a similar disrupted pattern in both clinical groups. Aspects of dispositional mindfulness were differentially associated with SC, which may suggest their potential role in novel transdiagnostic interventions.

The study applies a multiple and simultaneous structural model to demonstrate from the quantitative point of view that poverty is the result not only of simple variables such as income, the basket, the UBN and it was irrefutably demonstrated. This study was based on another study to evaluate the impact of TEKOPORA Program so called to the “conditional cash transfer” as part of state policy to reduce and overcome poverty in general and especially rural poverty. It was a representative sample at the level of the five poorest departments of Paraguay: Caaguazú, Concepcion, Canindeyú, San Pedro and Caazapá with over 2300 sampling units focused on the rural sector. With this assay poverty arises as the result of complex factors linking and interact simultaneously, structural and systemic and it must be taken into account to measure poverty and therefore to design more effective and efficient policies in the struggle for structural overcoming rural poverty. Therefore, measurement of poverty does not have to be reduced in the poverty line, or in the unsatisfied basic needs or in the integrated method. On the contrary, it must be studied through multiple causal, simultaneous and structural model.

The prevalence of childhood obesity continues to increase. Screen time, one of the most documented reasons for the obesogenic environment, enhances childhood obesity, since advertisements for unhealthy food products are still broadcast on channels for children. This is presently one of the main challenges for the government in Spain, since the current laws and obligations are not updated. This study aims to analyze food advertising aimed at children on Spanish television in 2013 and 2018 on children’s and general channels to test the effect of laws and obligations over time. In total, we viewed 512 h of the most viewed channels, two children’s and two general channels, during the week and on weekends during specific periods of 2013 and 2018. Food advertising was categorized as core, non-core, and other food advertisement (CFA, NCFA, and OFA, respectively) according to the nutritional profile. A total of 2935 adverts were analyzed, 1263 in 2013 and 1672 in 2018. A higher proportion of NCFAs were broadcast on children’s channels than in prior years, rising from 52.2% to 69.8% (p < 0.001). Nowadays, the risk of watching NCFAs on children’s channels compared to general channels turns out to be higher (Odds ratio > 2.5; p < 0.001), due to exposure to adverts for high-sugar and high-fat foods such as cakes, muffins, cookies, and fried and frozen meals rich in fat. In conclusion, the trends of nutritional profiles in food advertising on television are worsening over time, since the prevalence of NCFAs was higher in 2018 than in 2013. Currently, CFAs are not mainly broadcast on children’s channels, confirming high-risk exposure to non-core food advertising by watching them. Thus, food advertising laws and obligations should be adapted to increase compliance.

Context. Breast cancer (BC) requires a significant psychological adaptation once treatment is finished. There is growing evidence of how compassion training enhances psychological and physical well-being, however, there are very few studies analyzing the efficacy of compassion-based Interventions on BC survivors. Objective. To study the efficacy of the Cognitively-Based Compassion Training (CBCT) protocol in a BC survivor sample on quality of life, psychological well-being, fear of cancer recurrence, self-compassion, and compassion domains and mindfulness facets. Furthermore, enrollment, adherence, and satisfaction with the intervention were also analyzed. Methods. A randomized clinical trial was designed. Participants (n = 56) were randomly assigned to CBCT (n = 28) or a treatment-as-usual control group (TAU; n = 28). Pre-post intervention and 6-month follow-up measures took place to evaluate health-related quality of life, psychological well-being; psychological stress, coping strategies, and triggering cognitions; self-compassion and compassion; and mindfulness in both intervention and wait-list groups. Results. Accrual of eligible participants was high (77%), and the drop-out rate was 16%. Attendance to CBCT sessions was high and practice off sessions exceeded expectations). CBCT was effective in diminishing stress caused by FCR, fostering self-kindness and common humanity, and increasing overall self-compassion scores, mindful observation, and acting with awareness skillsets. Conclusion. CBCT could be considered a promising and potentially useful intervention to diminish stress caused by FCR and enhance self-kindness, common humanity, overall self-compassion, mindful observation, and acting with awareness skillsets. Nevertheless, future randomized trials are needed and a process of deeper cultural adaptation required.

Background: Individuals with eating disorders might be characterized by lower levels of direct engagement with the eating experience. This study aims to explore similarities and differences in direct experience while eating in four different weight conditions and healthy controls (HCs): anorexia nervosa (AN), bulimia nervosa (BN), eating disorders not otherwise specified (EDNOS), and obesity (OB).Methods: A total sample of 143 women were recruited. Participants were asked to eat an orange slice and write down 10 things about the experience of eating, classifying the focus of these thoughts as either experiential (“direct experience”) or analytical (“thinking about”). A direct experience index (DEI) was calculated by dividing the number of times a participant classified an experience as a “direct experience” (the numerator) by the total number of observations. Participants completed the Five Facet Mindfulness Questionnaire (FFMQ) and rated their level of anxiety after the task.Results: Between-groups significant differences were found on the DEI, with individuals in the OB group scoring higher than AN and BN, and similar to HC. After the task, the AN group reported significantly higher anxiety levels than HC, and EDNOS reported more anxiety than HC and OB. Between-group significant differences were also found for all the FFMQ facets. Conclusion: AN and BN presented lower access to direct experience while eating. Individuals with OB did not respond in the same way as the other clinical groups, showing a similar performance to HC.

O presente estudo consiste em uma revisão da literatura sobre a pesquisa em Ecocentrismo. O termo foi cunhado com o objetivo de especificar um conjunto de valores e crenças do ser humano sobre o seu relacionamento com o meio ambiente. Especialmente a partir da década de 1970, a ciência psicológica se interessou por essas crenças e valores como objeto de estudo. Com o fim de realizar a revisão da literatura, foram consultados indexadores nacionais (BVS-PSI e Scielo) e internacionais (ISI Web of Knowledge e Scopus), reunindo investigações em cinco temas centrais: 1- o papel da informação; 2- personalidade; 3- consumo verde; 4- aspectos culturais e papéis sociais; 5- a medida em ecocentrismo. A presente revisão conclui que é necessário um maior empenho em contribuições nacionais no campo, enquanto no cenário internacional há uma escassez de estudos sobre desenvolvimento humano e estratégias concretas de intervenção para a promoção de comportamentos pro-ambientais.

Regular mindfulness practice benefits people both mentally and physically, but many populations who could benefit do not practice mindfulness. Virtual Reality (VR) is a new technology that helps capture participants' attention and gives users the illusion of "being there" in the 3D computer generated environment, facilitating sense of presence. By limiting distractions from the real world, increasing sense of presence and giving people an interesting place to go to practice mindfulness, Virtual Reality may facilitate mindfulness practice. Traditional Dialectical Behavioral Therapy (DBT®) mindfulness skills training was specifically designed for clinical treatment of people who have trouble focusing attention, however severe patients often show difficulties or lack of motivation to practice mindfulness during the training. The present pilot study explored whether a sample of mindfulness experts would find useful and recommend a new VR Dialectical Behavioral Therapy (DBT®) mindfulness skills training technique and whether they would show any benefit. Forty four participants attending a mindfulness conference put on an Oculus Rift DK2 Virtual Reality helmet and floated down a calm 3D computer generated virtual river while listening to digitized DBT® mindfulness skills training instructions. On subjective questionnaires completed by the participants before and after the VR DBT® mindfulness skills training session, participants reported increases/improvements in state of mindfulness, and reductions in negative emotional states. After VR, participants reported significantly less sadness, anger, and anxiety, and reported being significantly more relaxed. Participants reported a moderate to strong illusion of going inside the 3D computer generated world (i.e., moderate to high "presence" in VR) and showed high acceptance of VR as a technique to practice mindfulness. These results show encouraging preliminary evidence of the feasibility and acceptability of using VR to practice mindfulness based on clinical expert feedback. VR is a technology with potential to increase computerized dissemination of DBT® skills training modules. Future research is warranted.

As fraturas diafisárias de fêmur e tíbia no adulto são, na sua maioria, tratadas cirurgicamente, geralmente através de osteossínteses intramedulares bloqueadas. Algumas fraturas diafisárias cominutivas e/ou muito desviadas podem representar um verdadeiro desafio técnico. As mesas de fraturas (ou ortopédicas), que permitem a estabilização instrumental vertical, horizontal e rotacional do membro, facilitam enormemente as manobras de redução e de colocação do implante e são amplamente utilizadas pelos cirurgiões ortopédicos. As fraturas diafisárias de úmero são, na sua maioria, tratadas não cirurgicamente. Entretanto, algumas requerem o tratamento cirúrgico, cujas indicações estão bem definidas na literatura. Podem ser fixadas através de placas ou de hastes intramedulares por via anterógrada ou retrógrada. No úmero, as manobras de redução da fratura e estabilização do membro para a implantação da haste intramedular são realizadas manualmente, geralmente por dois auxiliares e, por serem sujeitas à fadiga muscular, podem ser menos eficientes. O objetivo deste trabalho é apresentar um dispositivo externo de tração do membro superior para utilização em osteossínteses intramedulares bloqueadas anterógradas de fraturas diafisárias de úmero que permite a estabilização vertical, horizontal e rotacional do membro superior, de maneira similar àquela utilizada para os membros inferiores. O dispositivo é portátil, de construção simples, e pode ser instalado em qualquer mesa cirúrgica equipada com trilhos laterais. Foi utilizado no tratamento cirúrgico de 29 fraturas diafisárias de úmero com haste intramedular bloqueada anterógrada. Nossa experiência foi extremamente positiva. Não tivemos nenhuma complicação relacionada à sua utilização, que acreditamos ter facilitado, de maneira notável, os procedimentos cirúrgicos.Diaphyseal fractures of the femur and tibia in adults are mostly treated surgically, usually by means of intramedullary locked nail. Some comminuted and/or very deviated shaft fractures can represent a real technical challenge. The fracture table, which allows for the vertical, horizontal and rotational instrumental stabilization of the limb, greatly facilitates reduction and implant placement maneuvers and are widely used by orthopedic surgeons. Humeral shaft fractures are mostly treated nonsurgically. However, some whose indications are well defined in literature require surgical treatment. They can be fixed by plates, or by anterograde or retrograde intramedullary nail. In the humerus, limb fracture reduction and stabilization maneuvers for implantation of intramedullary nails are done manually, usually by 2 assistants. Because they are subject to muscle fatigue, this option may be less efficient. The aim of this paper is to present an external traction device for use in anterograde intramedullary fixation of humerus shaft fractures that allows vertical, horizontal and rotational stabilization of the upper limb similarly to that used in the lower limbs. The device is portable, of simple construction, and can be installed on any operating table equipped with side rails. It was used in the surgical treatment of 29 humeral shaft fractures with anterograde locked intramedullary nail. Our experience was extremely positive. We had no complications related to its use and we believe it to have facilitated the surgical procedures in a remarkable way.

O presente trabalho teve como objetivo analisar as relações das variáveis que tratam da percepção do estilo da chefia com os vínculos comprometimento, entrincheiramento e consentimento organizacional. Para tanto, foi construído e submetido a teste empírico um modelo explicativo, com o objetivo de identificar a contribuição das variáveis relativas à percepção do estilo de gestão na diferenciação desses vínculos com a organização. Participaram do estudo 994 trabalhadores de organizações com características diversas. O instrumento utilizado foi composto por escalas que mensuraram os três vínculos e as percepções dos participantes acerca do seu ambiente de trabalho, das políticas de gestão de pessoas da organização e do estilo da sua chefia imediata, além de perguntas sobre a caracterização da amostra. Para o estudo, foram conduzidas análises descritivas, correlações de Pearson e regressão linear (método Enter). Conforme os resultados, a variável que se correlaciona mais fortemente com os vínculos é a percepção de suporte organizacional. No caso do comprometimento e entrincheiramento, os itens que tratam sobre a percepção acerca da chefia foram os terceiros em ordem de força. O conjunto de variáveis independentes inseridas no modelo explicou 48,9% do comprometimento, 36,6% do consentimento e 22,3% do entrincheiramento.

Brain development in fetal life and early infancy is critical to determine lifelong performance in various neuropsychological domains. Metabolic pathologies such as overweight, obesity, and gestational diabetes in pregnant women are prevalent and increasing risk factors that may adversely affect long-term brain development in their offspring.The objective of this research was to investigate the influence of maternal metabolic pathologies on the neurodevelopment of the offspring at 6 and 18 months of life.This was a prospective case-control study of 331 mother- and child pairs from Granada, Spain. The mothers were included during pregnancy into four groups according to their pre-gestational body mass index and their gestational diabetes status; overweight (n:56), obese (n:64), gestational diabetic (n:79), and healthy normal weight controls (n:132). At 6 months and 18 months we assessed the children with the Bayley III scales of neurodevelopment.At 6 months (n=215), we found significant group differences in cognition composite language, and expressive language. Post hoc test revealed unexpectedly higher scores in the obese group compared to the normal weight group and a similar trend in overweight and diabetic group. The effects on language remained significant after adjusting for confounders with an adjusted odds ratio for a value above median in composite language score of 3.3 (95% CI: 1.1, 10.0; p=0.035) for children of obese mothers. At 18 month (n=197), the offspring born to obese mothers had lost five points in language composite scores and the previous differences in language and cognition was replaced by a suggestive trend of lower gross motor scores in the overweight, obese, and diabetic groups.Infants of obese mothers had a temporary accelerated development of cognition and language, followed by a rapid deceleration until 18 months of age, particularly of language scores. This novel observation prompts further confirmative studies to explore possible placental and neurodevelopmental mechanisms involved.
