Published: April 2023

BackgroundCitizens living in disadvantaged neighborhoods experience poorer health than the majority, and this inequality is a public health problem even in a welfare state such as Sweden. Numerous initiatives aimed at improving health and quality of life in these populations are being implemented and evaluated. Given that these populations are predominantly multicultural and multilingual, an instrument such as the WHOQOL-BREF, which is cross-culturally validated and available in multiple languages, may be appropriate. However, this cannot be ascertained since the psychometric properties of WHOQOL-BREF have never been assessed in the Swedish context. Thus, the current study aimed at assessing the psychometric properties of the WHOQOL-BREF questionnaire in citizens from a disadvantaged neighborhood in Southern Sweden.MethodsThe respondents in this study were 103 citizens who participated in the health promotional activities of a Health promotional program and also responded to the 26-item, WHOQOL-BREF questionnaire as a part of an evaluation to assess the impact of the activities on the health-related quality of life of citizens. A Rasch model using WINSTEP 4.5.1 was used to assess the psychometric properties in this study.ResultsFive of the 26 items, including pain and discomfort, dependence on medical substances, physical environment, social support, and negative feelings did not display acceptable goodness-of-fit to the Rasch model. On removing these items, the 21-item WHOQOL-BREF scale had an improved internal scale validity and person-separation reliability than the original 26-item version for this group of citizens from the neighborhood. When assessing the individual domains, three of the five items that were misfits on analyzing the full model also showed misfits in relation to two respective domains. When these items were removed, the internal scale validity of the domains also improved.ConclusionWHOQOL-BREF seemed to be psychometrically inadequate when used in the original form due to internal scale validity problems, while the modified 21-item scale seemed better at measuring the health-related quality of life of citizens living in socially disadvantaged neighborhoods in Sweden. Omission of items shall be done but with caution. Alternatively, future studies may also consider rephrasing the items with misfits and further testing the instrument with larger samples exploring the associations between subsamples and specific item misfit responses.

The obesity epidemic and its health consequences have not spared the population of kidney transplant (KTx) candidates and recipients. In addition, KTx recipients are susceptible to weight gain after transplantation. Overweight and obesity after KTx are strongly associated with adverse outcomes. Therefore, we designed a randomized controlled, mono-center study to specifically test the effectiveness of a primarily cognitive-behavioral approach supplemented by nutritional counseling for weight reduction following KTx as the intervention group (IG) in comparison to a brief self-guided intervention as control group (CG). The study was registered in the German Clinical Trials Register (DRKS-ID: DRKS00017226). Fifty-six KTx patients with a BMI from 27 to 40 kg/m2 were included in this study and randomized to the IG or CG. Main outcome was the number of participants achieving a 5% weight loss during the treatment phase. Additionally, participants were assessed 6 and 12 months after the end of the 6-month treatment phase. Participants significantly lost weight without group differences. 32.0% (n = 8) of the patients in the IG and 16.7% (n = 4) of the patients in the CG achieved a weight loss of 5% or more. Weight loss was largely maintained during follow-up. Retention and acceptance rate in the IG was high, with 25 (out of 28) patients completing all 12 sessions and one patient completing 11 sessions. Short-term, cognitive-behaviorally oriented weight loss treatment seems to be feasible and acceptable for patients after KTx who suffer from overweight or obesity. This clinical trial was ongoing at the onset of the COVID-19 pandemic which might have influenced study conduct and results.Clinical Trial Registration: https://clinicaltrials.gov/ DRKS-ID: DRKS00017226.

IntroductionUnderstanding the modulations of the medial prefrontal cortex (mPFC) in the valence of the stimulus from rewarding and aversive status to neutral status is crucial for the development of novel treatments for drug addiction. This study addressed this issue and examined whether optogenetic ChR2 photostimulation in the cingulate, prelimbic, and infralimbic cortices of the mPFC regulated the valence of saccharin solution consumption from the rewarding property, the aversive property induced by morphine’s conditioning, and the neutral states via saccharin extinction processes after morphine’s conditioning.MethodsAll rats received virus infection, buried optical fiber, optical stimulation, water deprivation, and saccharin solution consumption phases. In Experiment 1, rats were given ChR2 virus infection into the cingulate cortex (Cg1), prelimbic cortex (PrL), and infralimbic cortex (IL) to influence the rewarding saccharin solution consumption under photostimulation. In Experiment 2, rats were given ChR2 or EYFP virus infection into the Cg1, PrL, and IL to alter the saccharin solution consumption in the morphine-induced aversively conditioned taste aversion (CTA) and the saccharin solution consumption in the neutral state following the extinction process under photostimulation. Later, the immunohistochemical staining with c-Fos protein was performed for the Cg1, IL, PrL, nucleus accumbens core, nucleus accumbens shell, central amygdala, basolateral amygdala, ventral tegmental area, and dentate gyrus.ResultsThe results showed that optogenetic PrL stimulation decreased the rewarding valence of saccharin solution consumption and increased the morphine-induced, aversive valence of saccharin solution consumption. PrL stimulation decreased the neutral valence of saccharin solution consumption via the extinction process. Cg1 optogenetic stimulation increased the rewarding valence of saccharin solution consumption and the aversive valence of saccharin solution consumption induced by morphine in conditioning. Optogenetic IL stimulation increased the aversive valence of saccharin solution consumption induced by morphine via conditioning.ConclusionAltogether, optogenetic stimulation in the subareas of the mPFC modulated the reward, aversion, and neutral valences of the stimulus and altered neuronal activity in the mPFC, amygdala, nucleus accumbens, and hippocampus. Notably, the change of valence was temporary alternation during light-on related to the light-off periods. However, the findings may provide insights in the development of novel treatments for addictive symptoms.

BackgroundFunctional near-infrared spectroscopy (fNIRS) identifies neurophysiological differences between psychiatric disorders by assessing cortical hemodynamic function. Few trials have studied differences in brain functional activity between first-episode medication-naïve depression patients (FMD) and recurrent major depression (RMD). We aimed to determine the differences between FMD and RMD in oxygenated hemoglobin concentration ([oxy-Hb]), and to investigate the correlation between frontotemporal cortex activation and clinical symptoms.MethodsWe recruited 40 patients with FMD, 53 with RMD, and 38 healthy controls (HCs) from May 2021 to April 2022. Symptom severity was assessed with the 24-item Hamilton Depression Rating Scale (HAM-D) and the Hamilton Anxiety Rating Scale (HAM-A). A 52-channel fNIRS measured changes in [oxy-Hb] during VFT performance.ResultsBoth patient groups performed poorly during the VFT task compared with HC (FDR p &lt; 0.05), but there was no significant difference between the two patient groups. Analysis of variance showed that mean [oxy-Hb] activation was lower in both the frontal and temporal lobes in the MDD group compared with HCs (FDR p &lt; 0.05). Additionally, patients with RMD had a significantly lower hemodynamic response in the right dorsolateral prefrontal cortex (DLPFC) and dorsal frontal pole cortex (DFPC) than patients with FMD (FDR p &lt; 0.05). No significant correlation was found between changes in mean [oxy-Hb] and either medical history or clinical symptoms (FDR p &lt; 0.05).ConclusionThe presence of different neurofunctional activity in some of the same brain regions in FMD and RMD patients implied a link between the level of complexity activation in frontal regions and the stage of MDD. Cognitive impairment may already be present at the beginning of an MDD episode.Clinical trial registrationwww.chictr.org.cn, identifier ChiCTR2100043432.

IntroductionCOVID-related work changes have seriously disrupted employees’ familiar routines and hampered their lives and work. Although this topic has drawn rising attention, to our knowledge, limited studies have investigated the impact of COVID-related work changes on employees’ mentality and behavior. In this paper, we developed a moderated mediation model based on ego depletion theory to test how and when COVID-related work changes impact employees’ mental health, interpersonal conflict, and aggression behavior.MethodsWe collected 536 valid participants by conducting a questionnaire survey in a large Chinese manufacturing company, and tested our proposed theoretical model and hypotheses using SPSS 26.0 and Mplus 8.1.ResultsThe empirical results showed that COVID-related work changes would harm employees’ mental health and boost their interpersonal conflict and aggression via increasing their ego depletion. Moreover, trait resilience has an intervention in the relationship between COVID-related work changes and employees’ ego depletion, which weakens the indirect impact of COVID-related work changes on mental health, interpersonal conflict, and aggression.DiscussionThese findings suggest that although COVID-related work changes were inevitable, managers should take measures to improve the employees’ mental status and avoid conflicts promptly while taking steps to keep organizations on track.

Background and goal of studyCardiopulmonary resuscitation (CPR) in prehospital care is a major reason for emergency medical service (EMS) dispatches. CPR outcome depends on various factors, such as bystander CPR and initial heart rhythm. Our aim was to investigate whether short-term outcomes such as the return of spontaneous circulation (ROSC) and hospital admission with spontaneous circulation differ depending on the location of the out-of-hospital cardiac arrest (OHCA). In addition, we assessed further aspects of CPR performance.Materials and methodsIn this monocentric retrospective study, protocols of a prehospital physician-staffed EMS located in Munich, Germany, were evaluated using the Mann–Whitney U-test, chi-square test, and a multifactor logistic regression model.Results and discussionOf the 12,073 cases between 1 January 2014 and 31 December 2017, 723 EMS responses with OHCA were analyzed. In 393 of these cases, CPR was performed. The incidence of ROSC did not differ between public and non-public spaces (p = 0.4), but patients with OHCA in public spaces were more often admitted to the hospital with spontaneous circulation (p = 0.011). Shockable initial rhythm was not different between locations (p = 0.2), but defibrillation was performed significantly more often in public places (p &lt; 0.001). Multivariate analyses showed that hospital admission with spontaneous circulation was more likely in patients with shockable initial heart rhythm (p &lt; 0.001) and if CPR was started by an emergency physician (p = 0.006).ConclusionThe location of OHCA did not seem to affect the incidence of ROSC, although patients in public spaces had a higher chance to be admitted to the hospital with spontaneous circulation. Shockable initial heart rhythm, defibrillation, and the start of resuscitative efforts by an emergency physician were associated with higher chances of hospital admission with spontaneous circulation. Bystander CPR and bystander use of automated external defibrillators were low overall, emphasizing the importance of bystander education and training in order to enhance the chain of survival.

Published: April 2023

IntroductionDuring COVID-19, the mental health of Chinese university students has been a pressing concern. But the internal mechanism of perceived campus outdoor environment and learning engagement affecting college students’ mental health during the COVID-19 pandemic has not been fully discussed.MethodsThe current study used cross-sectional data from 45 Chinese universities to explore the relationship among perceptions of campus outdoor environments, learning engagement, and college student mental health, and focused on differences among college students in different grades.ResultsOur study revealed the mental health problems of Chinese college students during the COVID-19 pandemic were more severe. The mental health of postgraduates was generally poor, and their risk of depression was higher than that of undergraduates. More importantly, for postgraduates, the direct impact of the perceived campus outdoor environment on their mental health was stronger. For undergraduates, the indirect impact of learning engagement on the effect of the perceived campus outdoor environment on their mental health was stronger.ConclusionThe results of the study have implications for campus planners, landscape architects, and university planners to pay particular attention to the needs of postgraduates for campus outdoor environments, which is of great significance to improve the overall mental health of students during the COVID-19 pandemic.
La influencia de la inteligencia emocional sobre el síndrome burnout: una revisión sistemática
Authors: Soriano-Sánchez José-Gabriel , Jiménez-Vázquez David 
Published: April 2023

Emotional intelligence consists of the individual's ability to intuit and understand one's own feelings, allowing him/her to give a positive response to the various problems arising from emotions or feelings, while burnout is a state of fatigue or frustration, caused by the dedication to a cause, way of life or relationship, generating chronic work stress. However, a good level of emotional intelligence seems to have a positive influence on the person. Therefore, the aim of the present study was to analyze the relationship between emotional intelligence and burnout. After searching for scientific articles in international databases such as PsycINFO, Psicodoc, PubMed (MEDLINE), Scielo, Scopus, Sciencie Direct and Web of Science, as well as in the national electronic resource Dialnet, a total of 89 scientific articles were obtained which, after applying the established inclusion criteria, left 12 articles for review. The results of the studies included a sample size of 2.298 individuals from different fields, showing the relationship between both constructs. In conclusion, higher levels of emotional intelligence are related to lower burnout scores. Therefore, emotional intelligence is considered a protective variable against work-related stress that, consequently, develops the promotion of leadership, academic and professional engagement and personal well-being.

Published: April 2023

<p>In this paper, an unsupervised federated quantum generative adversarial network (UF-QGAN) is proposed to handle optimization issues in wireless communications. The proposed UF-QGAN considers unsupervised learning so that it could work without labelling for the training dataset. By adopting the federated framework, the computational load could be distributed between the cloud and edge. As a representative example, the proposed UF-QGAN is applied for non-orthogonal multiple access (NOMA). Achievable sum rate and complexity are investigated for the performance measure. Simulation results show that the UF-QGAN, which not requires data labeling, achieved a similar achievable sum rate compared to the supervised learning scheme. </p>

Published: April 2023

<p>The small-scale prosumers' decentralized cooperation and aggregation in energy communities are essential to increase renewable energy penetration and to ensure a successful energy transition. Despite their potential small-scale prosumers are not motivated to participate in local energy value chains due to a lack of trust and decentralized cooperation models for capturing local sustainability preferences, most innovation efforts are focused on financial incentives that are anyway very low. In this paper, we propose a solution for prosumers’ decentralized coordination using a cooperative game on top of a blockchain overlay by considering their complementary energy-related features and flexibility for self-sufficient energy communities. We define a governance model based on cooperative games and blockchain-sharing mechanisms reinforce the prosumers' trust to support the decentralized self-organization in coalitions to balance the renewable generation and demand. Self-enforcing smart contracts are used for the blockchain integration of the governance model to allow the decentralized creation and management of prosumers’ coalitions for optimized payoff distribution towards self-sufficiency and using tokens capturing the beyond-financial community level exchanges. The evaluation results show our solution's effectiveness in enabling prosumers to cooperate and create self-sufficient coalitions in a decentralized fashion with low gas consumption and transactional time overhead. </p>
