RESUMO

Las exigencias impuestas a los profesionales que trabajan con problemas psicológicos pueden resultar en un riesgo de agotamiento (Yang & Hayes, 2020). El objetivo de este estudio fue analizar el posible papel de la resiliencia como variable mediadora en la relación entre autocompasión y fatiga por compasión, burnout y satisfacción por compasión. Se utilizó un diseño de estudio descriptivo transversal. En el estudio participaron sesenta y cinco psicólogos clínicos (50 mujeres y 15 hombres) con edades comprendidas entre 23 y 71 años (M = 33.8, SD = 10.8). Los terapeutas completaron la Escala de Autocompasión, la Escala de Resiliencia de 14 ítems y la Escala de Calidad de Vida Profesional. Se probaron modelos de mediación simples separados para examinar en qué medida cada una de las variables de la escala de Resiliencia atenuó la relación entre Autocompasión y Calidad de Vida Profesional. Se realizaron modelos seriales de mediadores múltiples para explorar si las variables de resiliencia actuaban interactivamente como mediadores en la asociación entre la autocompasión y la calidad de vida profesional. Los análisis de mediación simples mostraron que la competencia personal fue un mediador parcial significativo en la relación entre la autocompasión y la satisfacción por la compasión y el agotamiento. La competencia personal y la aceptación de uno mismo y de la vida no fueron mediadores significativos de la relación entre la autocompasión y el estrés traumático secundario.(AU)


The demands placed on professionals working with psychologi-cal problems can result in a risk of burnout (Yang & Hayes, 2020). The ob-jective of this study was to analyze the possible role of resilience as a medi-ator variable in the relationship between self-compassion and compassion fatigue, burnout, and compassion satisfaction. A descriptive cross-sectional study design was used. Sixty-five clinical psychologists (50 women and 15 men) aged between 23 and 71 years (M= 33.8, SD= 10.8) participated in the study. The therapists completed the Self-Compassion Scale, the 14-Item Resilience Scale, and the Professional Quality of Life Scale. Separate simple mediation models were tested to examine the extent to which each of the Resilience scale variables attenuated the relationship between Self-compassion and Professional Quality of Life. Serial multiple mediator models were performed to explore whether Resilience variables acted in-teractively as mediators in the association between Self-compassion and Professional Quality of Life. Simple mediation analyses showed that Per-sonal Competence was a significant partial mediator in the relationship be-tween Self-Compassion and Compassion Satisfaction and Burnout. Per-sonal Competence and Acceptance of Self and Life were not significant mediators of the relationship between Self-Compassion and Secondary Traumatic Stress.(AU)

RESUMO

Rising ocean temperatures, a consequence of anthropogenic climate change, are increasing the frequency, intensity, and magnitude of extreme marine heatwaves (MHWs). These persistent anomalous warming events can have severe ecological and socioeconomic impacts, threatening ecologically and economically vital organisms such as bivalves and the ecosystems they support. Developing robust environmental and social frameworks to enhance the resilience and adaptability of bivalve aquaculture is critical to ensuring the sustainability of this crucial food source. This review synthesizes the current understanding of the physiological and ecological impacts of MHWs on commercially important bivalve species farmed globally. We propose an integrated risk assessment framework that encompasses environmental monitoring, farm-level preparedness planning, and community-level social support systems to safeguard bivalve aquaculture. Specifically, we examine heatwave prediction models, local mitigation strategies, and social programs that could mitigate the impacts on bivalve farms and vulnerable coastal communities economically dependent on this fishery. At the farm level, adaptation strategies such as selective breeding for heat-tolerant strains, optimized site selection, and adjustments to culture practices can improve survival outcomes during MHWs. Robust disease surveillance and management programs are essential for early detection and rapid response. Furthermore, we highlight the importance of stakeholder engagement, knowledge exchange, and collaborative governance in developing context-specific, inclusive, and equitable safeguard systems. Proactive measures, such as advanced forecasting tools like the California Current Marine Heat Wave Tracker developed by NOAA's Southwest Fisheries Science Center, enable preemptive action before losses occur. Coordinated preparation and response, underpinned by continuous monitoring and adaptive management, promise to protect these climate-vulnerable food systems and coastal communities. However, sustained research, innovation, and cross-sector collaboration are imperative to navigate the challenges posed by our rapidly changing oceans.

RESUMO

Popularly known as dopaminergic detox or dopamine fasting, it is a concept that aims at reducing dependence on instant satisfaction gratification and overstimulation to attain mental clarity, lessen anxiety, and be able to enjoy everyday events again. Digital detox has been a part of the dopamine fasting concept for several years now. However, some critics argue that this notion has no scientific proof behind it and may fail to deal with the problem of dopamine dysregulation. Some intense types of dopamine fasting which include extreme isolation or strict dieting can result in damage to mental health as well as physical fitness. The objective of the article is to understand what dopamine fasting means and see the literature and evidence available on the topic. Indexes like PubMed, Scopus, OVID, Embase, and Google Scholar were searched using the keywords to understand the existing knowledge about dopamine fasting. The literature review was then written to incorporate the understanding in a way that can be implemented practically. Recent studies have shown that individuals who engage in dopamine-fasting-like ideologies may experience reduced impulsive behaviors, increased focus on tasks, and reduced overwhelm. However, extreme forms of dopamine fasting can lead to feelings of loneliness, anxiety, and malnutrition, which can have detrimental effects on mental and physical health. Hence, the effects of dopamine fasting can vary greatly among individuals, and there is no one-size-fits-all approach. It is essential to consider individual needs and preferences when incorporating dopamine fasting into one's lifestyle and explore alternative practices that align with the principles of dopamine fasting. Understanding and respecting these differences is crucial in determining the most suitable strategies for maintaining a balanced dopamine response and overall psychological health. The benefits of dopamine fasting can be tremendous if done correctly but it depends on every individual to find the correct way and in the modern day, the practices can become tough to implement.

RESUMO

Background: The aim of this study was to classify distinct subgroups of adolescents based on the severity levels of their mobile phone addiction and to investigate how these groups differed in terms of their psychosocial characteristics. We surveyed a total of 2,230 adolescents using three different questionnaires to assess the severity of their mobile phone addiction, stress, anxiety, depression, psychological resilience, and personality. Latent class analysis was employed to identify the subgroups, and we utilized Receiver Operating Characteristic (ROC) curves and multinomial logistic regression for statistical analysis. All data analyses were conducted using SPSS 26.0 and Mplus 8.5. Methods: We classified the subjects into subgroups based on their mobile phone addiction severity, and the results revealed a clear pattern with a three-class model based on the likelihood level of mobile phone addiction (p < 0.05). We examined common trends in psychosocial traits such as age, grade at school, parental education level, anxiety levels, and resilience. ROC analysis of sensitivity versus 1-specificity for various mobile phone addiction index (MPAI) scores yielded an area under the curve (AUC) of 0.893 (95% CI, 0.879 to 0.905, p < 0.001). We also determined diagnostic value indices for potential cutoff points ranging from 8 to 40. The optimal cutoff value for MPAI was found to be >14, which corresponded to the maximum Youden index (Youden index = 0.751). Results: The latent classification process in this research confirmed the existence of three distinct mobile phone user groups. We also examined the psychosocial characteristics that varied in relation to the severity levels of addiction. Conclusion: This study provides valuable insights into the categorization of adolescents based on the severity of mobile phone addiction and sheds light on the psychosocial characteristics associated with different addiction levels. These findings are expected to enhance our understanding of mobile phone addiction traits and stimulate further research in this area.

RESUMO

BACKGROUND: Leveraging Alzheimer's disease (AD) imaging biomarkers and longitudinal cognitive data may allow us to establish evidence of cognitive resilience (CR) to AD pathology in-vivo. Here, we applied latent class mixture modeling, adjusting for sex, baseline age, and neuroimaging biomarkers of amyloid, tau and neurodegeneration, to a sample of cognitively unimpaired older adults to identify longitudinal trajectories of CR. METHODS: We identified 200 Harvard Aging Brain Study (HABS) participants (mean age = 71.89 years, SD = 9.41 years, 59% women) who were cognitively unimpaired at baseline with 2 or more timepoints of cognitive assessment following a single amyloid-PET, tau-PET and structural MRI. We examined latent class mixture models with longitudinal cognition as the dependent variable and time from baseline, baseline age, sex, neocortical Aß, entorhinal tau, and adjusted hippocampal volume as independent variables. We then examined group differences in CR-related factors across the identified subgroups from a favored model. Finally, we applied our favored model to a dataset from the Alzheimer's Disease Neuroimaging Initiative (ADNI; n = 160, mean age = 73.9 years, SD = 7.6 years, 60% women). RESULTS: The favored model identified 3 latent subgroups, which we labelled as Normal (71% of HABS sample), Resilient (22.5%) and Declining (6.5%) subgroups. The Resilient subgroup exhibited higher baseline cognitive performance and a stable cognitive slope. They were differentiated from other groups by higher levels of verbal intelligence and past cognitive activity. In ADNI, this model identified a larger Normal subgroup (88.1%), a smaller Resilient subgroup (6.3%) and a Declining group (5.6%) with a lower cognitive baseline. CONCLUSION: These findings demonstrate the value of data-driven approaches to identify longitudinal CR groups in preclinical AD. With such an approach, we identified a CR subgroup who reflected expected characteristics based on previous literature, higher levels of verbal intelligence and past cognitive activity.

RESUMO

The eMalahleni Local Municipality (eLM) in Mpumalanga province, South Africa, has a number of informal settlements because of the influx of people seeking employment in the municipal area. These informal settlements are exposed to a number of hazards, including underground fires, air and water pollution, sinkholes, abandoned mining areas and acid mining drainage. South Africa's National Development Plan (NDP) incorporates the United Nation's Sustainable Development Goals, which are intended to upgrade informal settlements on suitable land. The Department of Human Settlement recognised the gap in the policy because upgrading only included physical structures and did not include adaptive capacity for communities to create resilience to withstand disasters. The researcher used a case study research design for the inquiry intended to recommend adaptive capacity and reduce disaster risks in informal settlements in the eLM. Purposive sampling was used to select 25 participants from eLM, provincial government departments and informal settlements. The data were analysed using thematic analysis based on the study's conceptual framework. The research findings revealed that the government has not done much to involve vulnerable communities during the development of policies to reduce disaster risks within informal settlements. In particular, the failure of the government to promote and reinforce public participation in disaster risk reduction programmes leaves the vulnerable communities defenceless. Contribution: This study strengthens the intergovernmental structures and public participation to reduce disaster risks in communities. This study discourages a silos mentality and encourages coordination between government departments to identify root causes by applying the pressure and release model for effective disaster risk reduction.

RESUMO

BACKGROUND: Social isolation measures by the COVID-19 pandemic have impacted teaching work. In an "Emergency Remote Teaching" (ERT) context, it is relevant to investigate the factors that affect teachers' self-efficacy. METHODS: A total of 289 teachers from schools in southern Spain have participated in this study. They have been asked about their levels of burnout, engagement, and resilience. Comparisons were made by groups in accordance with sex, type of center they belonged to, school social context, and educational level in which the teacher taught. Using a Structural Equations Model, the multivariate relationships between the variables related to burnout, engagement, and resilience were described. RESULTS: During the ERT, teachers' self-efficacy was influenced by the 3 factors: burnout-exhaustion and cynicism-engagement, and resilience. During the ERT, the teachers in semi-private and private centers showed greater self-efficacy. In turn, the teachers in childhood and primary education showed a significantly higher level of work engagement than the teachers in compulsory and post-compulsory secondary education. CONCLUSIONS: The results in relation to ERT are discussed in the context of the exceptionality and universal globality of the pandemic phenomenon and the complex self-perception of the social value of the teaching function.

RESUMO

Background: Meaning in life is a crucial aspect of psychological well-being, often overlooked despite its clinical significance. This warrants further investigation, especially regarding its relationship with frailty and psychological resilience. Objective: This study aims to assess the status and relevance of frailty, psychological resilience, and meaning in life among older adults in Chinese nursing homes. Additionally, it explores the mediating role of psychological resilience between frailty and meaning in life, providing insights to improve the meaning in life for older adults in nursing homes. Methods: Between August 2022 and November 2022, 302 older adults in Chinese nursing homes were selected using convenience sampling. The study utilized the Socio-demographic Characteristics Questionnaire, Tilburg Frailty Indicator, Connor-Davidson Resilience Scale, and the Source of Meaning Scale for Older Adults. A face-to-face questionnaire survey was conducted, and SPSS 27.0 was employed for analyzing correlations between frailty, psychological resilience, and meaning in life. The mediating effect of psychological resilience was assessed using Model 4 in the Process plug-in. Results: Older adults in nursing homes exhibited a frailty total score of 4.00 (2.00, 5.00), with a prevalence of 28.5%. Psychological resilience scored 66.00 (51.75, 76.00), and meaning in life scored 149.00 (132.00, 158.25). Frailty showed a negative correlation with both meaning in life and psychological resilience, while meaning in life demonstrated a positive correlation with psychological resilience. Psychological resilience exhibited a partial mediating effect, accounting for 51.04% of the total effect between frailty and meaning in life. Conclusion: Frailty incidence is high among older adults in nursing homes, with psychological resilience at a general level and meaning in life in the upper middle level. Psychological resilience plays a crucial role as a partial mediator between frailty and meaning in life. Timely assessment of frailty, targeted interventions, and improvements in psychological resilience are essential for enhancing the meaning in life and promoting successful aging.

RESUMO

AIM: The study aimed to determine the factors affecting psychological resilience, self-efficacy and job satisfaction in nurse academics. BACKGROUND: Nurse academics follow an emotionally and mentally intense career path, along which they are required to balance many different roles and responsibilities, including teaching, research and guidance. However, in some cases, this equilibrium is disrupted and may cause functional disruptions; in achieving this balance, resilience, self-efficacy and job satisfaction play important roles. METHODS: The data of this cross-sectional study were collected between January and April 2023, and 446 nurse academics were included in the study. The Descriptive Characteristics Information Form, Brief Psychological Resilience Scale (BPRS), General Self-Efficacy Scale (GSES) and Job Satisfaction Scale (JSS) were used to collect the research data.We adhered to the STROBE checklist for reporting. RESULTS: A significant positive relationship was found between general self-efficacy levels and psychological resilience and job satisfaction levels. There is a significant positive relationship between job satisfaction levels and age, total years of service, psychological resilience and general self-efficacy levels. In addition, it has been noted that family relationships, friend relationships and academic title factors were effective on the nurse academics' psychological resilience, self-efficacy and job satisfaction levels. CONCLUSION: Managers can play an important role in increasing the psychological resilience, self-efficacy and job satisfaction levels of nurse academics by developing strategies for these effective factors. IMPLICATIONS FOR NURSING AND NURSING POLICY: Governments need to ensure that nurse academics have an appropriate career framework that enables them to balance the competing demands on their time and that they have adequate mentoring and support in the early stages of their careers to enable them to adapt to working life as a nurse academic.

RESUMO

The dynamicity of the mitochondrial network is crucial for meeting the ever-changing metabolic and energy needs of the cell. Mitochondrial fission promotes the degradation and distribution of mitochondria, while mitochondrial fusion maintains mitochondrial function through the complementation of mitochondrial components. Previously, we have reported that mitochondrial networks are tubular, interconnected, and well-organized in young, healthy C. elegans, but become fragmented and disorganized with advancing age and in models of age-associated neurodegenerative disease. In this work, we examine the effects of increasing mitochondrial fission or mitochondrial fusion capacity by ubiquitously overexpressing the mitochondrial fission gene drp-1 or the mitochondrial fusion genes fzo-1 and eat-3, individually or in combination. We then measured mitochondrial function, mitochondrial network morphology, physiologic rates, stress resistance, and lifespan. Surprisingly, we found that overexpression of either mitochondrial fission or fusion machinery both resulted in an increase in mitochondrial fragmentation. Similarly, both mitochondrial fission and mitochondrial fusion overexpression strains have extended lifespans and increased stress resistance, which in the case of the mitochondrial fusion overexpression strains appears to be at least partially due to the upregulation of multiple pathways of cellular resilience in these strains. Overall, our work demonstrates that increasing the expression of mitochondrial fission or fusion genes extends lifespan and improves biological resilience without promoting the maintenance of a youthful mitochondrial network morphology. This work highlights the importance of the mitochondria for both resilience and longevity.

RESUMO

BACKGROUND: Resilience-promoting resources are critically needed to support positive caregiving experiences for multiple sclerosis (MS) caregivers. A digital toolkit offers a flexible way to access and use evidence-based resources that align with MS caregivers' interests and needs over time. OBJECTIVE: We explored the perspectives of key knowledge users regarding content areas, features, and other considerations to inform an MS caregiver resilience digital toolkit. METHODS: Twenty-two individuals completed a demographic survey as part of this study: 11 MS family caregivers, 7 representatives of organizations providing support services for people with MS and/or caregivers, and 4 clinicians. We conducted nine semi-structured individual interviews and two focus groups. Data were analyzed using content analysis. RESULTS: Participants recommended that a digital toolkit should include content focused on promoting MS caregivers' understanding of the disease, its trajectory and available management options, and enhancing caregiving skills and caregivers' ability to initiate and maintain behaviours to promote their own well-being. Features that allow for tracking and documenting care recipients' and caregivers' experiences, customization of engagement, and connectivity with other sources of support were also recommended. Participants suggested a digital toolkit should be delivered through an app with web browser capabilities accessible on smartphones, tablets, or laptops. They also acknowledged the need to consider how users' previous technology experiences and issues related to accessibility, usability, privacy and security could influence toolkit usage. CONCLUSION: These findings will guide future toolkit development and evaluation. More broadly, this study joins the chorus of voices calling for critical attention to the well-being of MS family caregivers.

RESUMO

Organisms experience constant nutritional flux. Mechanisms at the interface of opposing nutritional states-scarcity and surplus-enable organismal energy homeostasis. Contingent on nutritional stores, adipocytes secrete adipokines, such as the fat hormone leptin, to signal nutrient status to the central brain. Increased leptin secretion underlies metabolic dysregulation during common obesity, but the molecular mechanisms regulating leptin secretion from human adipocytes are poorly understood. Here, we report that Atg8/LC3 family proteins, best known for their role in autophagy during nutrient scarcity, play an evolutionarily conserved role during nutrient surplus by promoting adipokine secretion. We show that in a well-fed state, Atg8/LC3 promotes the secretion of the Drosophila functional leptin ortholog unpaired 2 (Upd2) and leptin from human adipocytes. Proteomic analyses reveal that LC3 directs leptin to a secretory pathway in human cells. We identified LC3-dependent extracellular vesicle (EV) loading and secretion (LDELS) as a required step for leptin release, highlighting a unique secretory route adopted by leptin in human adipocytes. In Drosophila, mutations to Upd2's Atg8 interaction motif (AIM) result in constitutive adipokine retention. Atg8-mediated Upd2 retention alters lipid storage and hunger response and rewires the bulk organismal transcriptome in a manner conducive to starvation survival. Thus, Atg8/LC3's bidirectional role in nutrient sensing-conveying nutrient surplus and responding to nutrient deprivation-enables organisms to manage nutrient flux effectively. We posit that decoding how bidirectional molecular switches-such as Atg8/LC3-operate at the nexus of nutritional scarcity and surplus will inform therapeutic strategies to tackle chronic metabolic disorders.

RESUMO

There is scant understanding of what supports African emerging adults who are not in employment, education or training (i.e., NEET) to show resilience to NEET-related challenges. This article narrows that gap by reporting an iterative phenomenological study with nine African emerging adults (mean age: 23.44; 66% female) who were NEET for the 18-month duration of the study and living in a resource-constrained community in South Africa. We interviewed each young person three times (June 2021; December 2021; June 2022). A reflexive thematic analysis of these interview transcripts showed that being NEET is a multifaceted challenge. Supported by a mix of personal, relational and environmental resources, young people managed this challenge by resisting or recuperating from destructive coping mechanisms and believing in a successful future self. These findings point to the importance of young people and their social ecologies (families, peers, service providers and policymakers) recognising and enacting their co-responsibility for resilience to the compound challenges of being NEET.

RESUMO

MYC has been implicated in the pathogenesis of a wide range of human tumors and has been described for many years as a transcription factor that regulates genes with pleiotropic functions to promote tumorigenic growth. However, despite extensive efforts to identify specific target genes of MYC that alone could be responsible for promoting tumorigenesis, the field is yet to reach a consensus whether this is the crucial function of MYC. Recent work shifts the view on MYC's function from being a gene-specific transcription factor to an essential stress resilience factor. In highly proliferating cells, MYC preserves cell integrity by promoting DNA repair at core promoters, protecting stalled replication forks, and/or preventing transcription-replication conflicts. Furthermore, an increasing body of evidence demonstrates that MYC not only promotes tumorigenesis by driving cell-autonomous growth, but also enables tumors to evade the host's immune system. In this review, we summarize our current understanding of how MYC impairs antitumor immunity and why this function is evolutionarily hard-wired to the biology of the MYC protein family. We show why the cell-autonomous and immune evasive functions of MYC are mutually dependent and discuss ways to target MYC proteins in cancer therapy.

RESUMO

Northern temperate and boreal forests are large biomes playing crucial ecological and environmental roles, such as carbon sequestration. Despite being generally remote, these forests were exposed to anthropogenic nitrogen (N) deposition over the last two centuries and may still experience elevated N deposition as human activities expand towards high latitudes. However, the impacts of long-term high N deposition on these N-limited forest ecosystems remain unclear. For 18 years, we simulated N deposition by chronically adding ammonium nitrate at rates of 3 (LN treatment) and 10 (HN treatment) times the ambient N deposition estimated at the beginning of the experiment at a temperate sugar maple and a boreal balsam fir forest site, both located in northeastern America. LN and HN treatments corresponded respectively to addition of 26 kgN·ha-1·yr-1 and 85 kgN·ha-1·yr-1 at the temperate site and 17 kgN·ha-1·yr-1 and 57 kgN·ha-1·yr-1 at the boreal site. Between 2002 and 2018, soil solution was collected weekly during summer and concentrations of NO3-, NH4+, Ca2+ and pH were measured, totalling ~12,700-13,500 observations per variable on the study period. N treatments caused soil solution NO3-, NH4+ and Ca2+ concentrations to increase while reducing its pH. However, ion responses manifested through punctual high concentration events (predominantly on the HN plots) that were very rare and leached N quantity was extremely low at both sites. Therefore, N addition corresponding to 54 years (LN treatment) and 180 years (HN treatment) of accelerated ambient N deposition had overall small impacts on soil solution chemistry. Our results indicate an important N retention of northeastern American forests and an unexpected strong resilience of their soil solution chemistry to long-term simulated N deposition, potentially explained by the widespread N-limitation in high latitude ecosystems. This finding can help predict the future productivity of N-limited forests and improve forest management strategies in northeastern America.

RESUMO

BACKGROUND: Severe trauma accounts for a main factor inducing mortality for individuals aged < 45 years in China, which requires admission to intensive care unit (ICU) to receive comprehensive treatment. Family members of patients with unanticipated and life-threatening trauma during their ICU stays often experience psychosocial distress due to illness uncertainty. Previous research has shown that family function and psychological resilience are associated with illness uncertainty, respectively. However, little is known about the current situation and interacting mechanism between family function, psychological resilience, and illness uncertainty of family members for ICU trauma patients. Therefore, this study focused on exploring the current situation and relationships between these three factors in family members for ICU trauma patients. METHODS: The convenience sampling approach was adopted in the present cross-sectional survey, which involved 230 family members for ICU trauma patients from 34 hospitals in Chongqing, China. Related data were extracted with self-reporting questionnaires, which included sociodemographic characteristic questionnaire, the Family Adaptability, Partnership, Growth, Affection and Resolve Scale (APGAR), the 10-item Connor-Davidson Resilience Scale (10-CD-RISC) and the Mishel's Illness Uncertainty Scale for Family Members (MUIS-FM). Pearson correlation analysis was conducted to examine the correlations between various variables. Additionally, a structural equation model was adopted to assess the mediating effect of psychological resilience on family function and illness uncertainty. RESULTS: According to our results, family members for ICU trauma patients experienced high illness uncertainty with moderate family dysfunction and low psychological resilience. Family function directly affected illness uncertainty and indirectly affected illness uncertainty through psychological resilience in family members of ICU trauma patients. CONCLUSIONS: Family function and psychological resilience are the protective factors for reducing illness uncertainty. Healthcare providers should take effective measures, including family-functioning improvement and resilience-focused interventions, for alleviating illness uncertainty in family members of ICU trauma patients.

RESUMO

BACKGROUND: Periodontal diseases are associated with dysbiosis in the oral microbial communities. Managing oral biofilms is therefore key for preventing these diseases. Management protocols often include over-the-counter antimicrobial mouth rinses, which lack data on their effects on the oral microbiome's ecology, bacterial composition, metabolic activity, and dysbiosis resilience. This study examined the efficacy of antimicrobial mouth rinses to halt dysbiosis in in vitro oral biofilms under periodontitis-simulating conditions. METHODS: Multispecies oral biofilms were grown on hydroxyapatite discs (HADs) and rinsed daily with one of six mouth rinses. Positive and negative controls were included. After three rinses, biofilms were analyzed with viability quantitative polymerase chain reaction and visualized using scanning electron microscopy. Supernatants of rinsed biofilms were used for metabolic activity analysis. In addition, human oral keratinocytes were exposed to rinsed biofilms to assess their inflammatory response. All outputs were analyzed for correlation using Spearman coefficient. RESULTS: Product-related changes were observed in the rinsed biofilms. Three of the six tested mouth rinses could significantly prevent dysbiosis with ≥30% reduction in pathobiont abundance relative to the control. These biofilms had lower metabolic activity, and the exposed human oral keratinocyte produced less interleukin-8. Interleukin-8 production correlated to both pathobiont quantity and the metabolic activity of the biofilms. CONCLUSION: Some mouth rinses could support biofilm resilience and stop dysbiosis evolution in the biofilm model, with a clear product-related effect. Such mouth rinses can be considered for patients under maintenance/supportive periodontal therapy to prevent/delay disease recurrence. Others are more useful for different periodontal therapy stages.

RESUMO

BACKGROUND: This study investigates seafarers' loneliness as a mediating variable between psychological well-being and resilience, and tests resilience as a mediating variable between psychological well-being and loneliness. It also examines the challenges faced by seafarers on different types of ships and evaluates the mediating roles of resilience and loneliness. MATERIALS AND METHODS: The research uses descriptive data analysis, reliability analysis, correlation analysis, and mediation analysis with bootstrap-based regression models. An online survey was conducted with 471 active Turkish seafarers using a sociodemographic questionnaire and three standardized scales measuring psychological well-being (PW), loneliness at work (LAW), and psychological resilience (PR). Data were collected between 01/07/2023 and 01/09/2023. RESULTS: The findings indicate that ship type is a significant factor in the mediating roles of loneliness at work and psychological resilience. There is a partial mediating role of loneliness at work and resilience in psychological well-being across different ship types. Specifically, loneliness at work partially mediates the relationship between psychological resilience and psychological well-being among seafarers on tanker or bulk carrier vessels, but not on container vessels. CONCLUSIONS: The study concludes with suggestions to address the mental health challenges faced by seafarers, emphasizing the importance of ship type in the mediating roles of loneliness and resilience. Regarding the mediating role of loneliness at work, it has been determined that there is partial mediation between psychological resilience and psychological well-being among seafarers working on tanker or bulk carrier vessels. However, on container vessels, loneliness at work does not mediate the relationship between psychological well-being and psychological resilience. Based on these findings, the authors conclude by offering a range of helpful solutions to address this problem.

RESUMO

BACKGROUND: Research suggests that maternal ACEs have intergenerational consequences for offspring mental health. However, very few studies have investigated moderators of this association. OBJECTIVES: The objective of this longitudinal study was to examine whether child resilience factors moderated the association between maternal ACEs prior to age 18, and child-reported symptoms of anxiety, depression, hyperactivity, and inattention. PARTICIPANTS AND SETTING: The current study used data from 910 mother-child dyads. Participants were recruited in pregnancy from 2008 to 2010 as part of a longitudinal cohort study. METHODS: Mothers had previously completed an ACEs questionnaire and reported on their child's resilience factors at child age 8-years. Children completed questionnaires about their mental health problems (symptoms of anxiety, depression, hyperactivity, and attention problems) at ages 10 and 10.5 years. Four moderation models were performed in total. RESULTS: Results revealed that maternal ACEs predicted child-reported symptoms of anxiety (ß = 0.174, p = .02) and depression (ß = 0.37, p = .004). However, both these associations were moderated by higher levels of perceived child resilience factors (ß = -0.29, p = .02, ß = -0.33, p = .008, respectively). Specifically, there was no association between maternal ACEs and child mental health problems in the context of moderate and high levels of child resilience factors. CONCLUSIONS: Children who have the ability to solicit support from internal and external sources (e.g., being creative, setting realistic goals, making friends easily) may be buffered against the consequences of maternal ACEs on anxiety and depression. Thus, the effects of maternal ACEs on child mental health problems are not deterministic.

RESUMO

There are many opportunities for urologists to be emotionally impacted, and possibly injured, in the regular course of their work. In particular, urologists are vulnerable to become Second Victims as a result of errors, adverse events, and distressing clinical events. This article reviews best practices that individuals, training programs, hospitals, and healthcare systems can implement to intentionally and programmatically mitigate the short and long-term effects on healthcare professionals.
