RESUMO

Introduction: Forced migration affect the health and wellbeing of millions of women. The aim was to explore experiences of trauma-informed care among women who are forced migrants. Methods: This was an exploratory qualitative study. Eleven women who had concluded treatment at multidisciplinary trauma centers in Sweden were interviewed, recruited through consecutive sampling. Audio-recorded interviews were transcribed and analyzed with systematic text condensation. Results: Women dealt with mental and physical manifestations in a challenging psychosocial situation. Various structural and individual barriers were addressed that hindered access to adequate health services. Women appreciated various benefits of the treatment and recalled the care as supportive and compassionate. However, undergoing treatment was considered demanding, requiring significant determination and energy. Participants suggested that peer support could enhance the support. Conclusions: Migrant women experience a range of health-related burdens and encounter barriers to trauma-informed care. While demanding, treatment has the potential to alleviate symptoms. Health professionals and stakeholders providing trauma-informed care need to ensure that their services are accessible and culturally sensitive towards the unique needs of women. Peer support has the potential to enhance support further, which need further evaluation.

RESUMO

The objective of this scoping review was to systematically review the literature on how non-financial conflicts of interest (nfCOI) are defined and evaluated, and the strategies suggested for their management in health-related and biomedical journals. PubMed, Embase, Scopus and Web of Science were searched for peer reviewed studies published in English between 1970 and December 2023 that addressed at least one of the following: the definition, evaluation, or management of non-financial conflicts of interest. From 658 studies, 190 studies were included in the review. nfCOI were discussed most commonly in empirical (22%; 42/190), theoretical (15%; 29/190) and "other" studies (18%; 34/190) - including commentary, perspective, and opinion articles. nfCOI were addressed frequently in the research domain (36%; 68/190), publication domain (29%; 55/190) and clinical practice domain (17%; 32/190). Attitudes toward nfCOI and their management were divided into two distinct groups. The first larger group claimed that nfCOI were problematic and required some form of management, whereas the second group argued that nfCOI were not problematic, and therefore, did not require management. Despite ongoing debates about the nature, definition, and management of nfCOI, many articles included in this review agreed that serious consideration needs to be given to the prevalence, impact and optimal mitigation of non-financial COI.

RESUMO

BACKGROUND: The increasing costs of nurses' occupational-stress, conflicts, and violence within healthcare services have raised international interest. Yet, research/interventions should consider that perceived stress and conflicts- but also potential resources- within the wards can crossover the healthcare settings, impacting nurses' private lives and viceversa, potentially creating vicious circles exacerbating stress, conflicts/violence or, conversely, virtuous circles of psychological/relational wellbeing. Based on the Demands-Resources-and-Individual-Effects (DRIVE) Nurses Model, and responding to the need to go in-depth into this complex dynamic, this study aims to explore potential vicious circles featured by the negative effects of the interplay (main/mediating effects) between perceived stressors in nursing linked to interpersonal conflicts (Conflicts-with-Physicians, Peers, Supervisors, Patients/their families), work-family inter-role conflicts (Work-Family/Family-Work-Conflicts), and work-related stress (Effort-Reward-Imbalance) on nurses' psychological/relational health (Anxiety, Depression, Somatization, Interpersonal-Sensitivity, Hostility). The potential moderating role of work-resources (Job-Control, Social-Support, Job-Satisfaction) in breaking vicious circles/promoting virtuous circles was also explored. METHOD: The STROBE Checklist was used to report this cross-sectional multi-centre study. Overall, 265 nurses completed self-report questionnaires. Main/mediating/moderating hypotheses were tested by using Correlational-Analyses and Hayes-PROCESS-tool. RESULTS: Data confirmed the hypothesized detrimental vicious circles (main/mediating effects), impairing nurses' psychological health conditions at individual level (Anxiety, Depression, Somatization), but also at relational level (Hostility and Interpersonal-Sensitivity). The moderating role of all work resources was fully supported. CONCLUSION: Findings could be used to implement interventions/practices to effectively prevent the maintenance/exacerbation of vicious circles and promote psychological/relational wellbeing in healthcare settings and beyond.

RESUMO

Nudging, a controversial technique for modifying people's behavior in a predictable way, is claimed to preserve freedom of choice while simultaneously influencing it. Nudging had been largely confined to situations such as promoting healthy eating choices but has been employed in the coronavirus disease 2019 (COVID-19) crisis in a shift towards measures that involve significantly less choice, such as shoves and behavioral prods. Shared decision making (SDM), a method for direct involvement and autonomy, is an alternative approach to communicate risk. Predominantly peer-reviewed scientific publications from standard literature databases like PubMed, PsycInfo, and Psyndex were evaluated in a narrative review. The so-called fear nudges, as well as the dissemination of strongly emotionalizing or moralizing messages can lead to intense psycho-physical stress. The use of these nudges by specialized units during the COVID-19 pandemic generated a societal atmosphere of fear that precipitated a deterioration of the mental and physical health of the population. Major recommendations of the German COVID-19 Snapshot Monitoring (COSMO) study, which are based on elements of nudging and coercive measures, do not comply with ethical principles, basic psychological principles, or evidence-based data. SDM was misused in the COVID-19 crisis, which helped to achieve one-sided goals of governments. The emphasis on utilitarian thinking is criticized and the unethical behavior of decision makers is explained by both using the concept of moral disengagement and the maturity level of coping strategies. There should be a return to an open-ended, democratic, and pluralistic scientific debate without using nudges. It is therefore necessary to return to the origins of SDM.

RESUMO

BACKGROUND: Alcohol industry organisations occupy a prominent position in UK alcohol policy, but their involvement has been contested by public health bodies on the basis that a conflict of interest (COI) exists between their economic objectives and those of public health. There are ongoing debates in the research literature about how to conceptualise COI and mitigate this in health research and practise. However, less attention has been paid to these issues in relation to the alcohol industry specifically. This article explores similarities and differences in beliefs among alcohol policy actors regarding COI and the implications of engagement with the alcohol industry in the context of UK public health policy. METHODS: Semi-structured interviews with a range of policy actors (n=26) including medical professionals, parliamentarians, civil servants, academic researchers, health campaigners, and alcohol industry representatives. Interviews with alcohol industry representatives were supplemented with an analysis of industry responses to a public consultation. All data was thematically coded using NVivo software. RESULTS: Two competing "coalitions" were identified, expressing beliefs about COI linked to alcohol industry engagement. Both divergent and convergent beliefs were expressed by the two coalitions in relation to the type of industry actor, form of engagement, the policy issue under discussion and the stage of policy process. CONCLUSION: Alcohol policy is a complex and contested space in which policy actors have differing, nuanced and contingent understandings of COI and identify varying risks associated with alcohol industry engagement. In identifying the areas of convergence and diversion in both understanding and evaluation of COI in alcohol-specific settings, these findings will assist both decision-makers and non-governmental actors in developing policies and guidelines to manage potential COI in future.

RESUMO

OBJECTIVE: Suicide attempt (SA) is the strongest predictive variable for completed suicide. The Department of Cauca in Colombia has an SA rate higher than the national average, but the factors are unknown. The objective was to identify the profiles of SA in children and adolescents of Cauca. METHODS: Cross-sectional study, which included all SA (Event-356) records from the SIVIGILA platform in children under 18 years of age between 2016 and 2019. The authors described the variables and multiple correspondence analysis with the Burt method, according to the completeness of the data to establish the possible SA profiles using STATA 15.1, and R. The Ethics Committee at Universidad del Cauca approved it. RESULTS: The study found 977 SA during this period, 72.4% female, 97.1% adolescent, 74.4% mestizo, 19.3% indigenous, 45.3% resided in municipalities exposed to the armed conflict, 32.3% expressed ideation and previous attempts, and 15.5% prior attempts. The MCA included 810 SA and identified three profiles: "Classic", which had mestizo adolescents with a history of prior SA, mental illness, or psychoactive substance use problems; "Related to the armed conflict", which included female adolescents with a first SA and residents in municipalities exposed to the armed conflict; "Ethnic" represented by male indigenous, with housing in a rural area. CONCLUSION: The SA profiles found in Cauca were "Classic", "Related to the armed conflict", and "Ethnic"; these can be considered to implement prevention strategies from a cross-cultural, mental health, and gender perspective, with the presence of the state in the territories.

RESUMO

In wildlife management, differing perspectives among stakeholders generate conflicts about how to achieve disparate sustainability goals that include ecological, economic, and sociocultural dimensions. To mitigate such conflicts, decisions regarding wildlife management must be taken thoughtfully. To our knowledge, there exists no integrative modeling framework to inform these decisions, considering all dimensions of sustainability. We constructed a decision-support tool based on stakeholder workshops and a Bayesian decision network to inform management of wild ruminants in the federal state of Lower Austria. We use collaborative decision analysis to compare resource allocations while accounting for trade-offs among dimensions of sustainability. The tool is designed for application by non-technical users across diverse decision-making contexts with particular sets of wildlife management actions, objectives, and uncertainties. Our tool represents an important step toward developing and evaluating a transparent and replicable approach for mitigating wildlife-based conflicts in Europe and beyond.

RESUMO

Introduction: Adolescent suicide is a prevalent issue globally, with various factors contributing to this phenomenon. This study aimed to investigate these factors and their interrelationships to better understand the causes of adolescent suicide and provide evidence for its prevention. Methods: This study conducted among middle school students in Liaoning Province, China, from April to May 2016, A cross-sectional survey was administered to 1,028 students aged 10-19, using instruments such as the Behavior Questionnaire-Revised (SBQ-R), Children's Perception of Interparental Conflict Scale (CPIC), and revised version of Inventory of Parent Attachment (IPPA-R). Result: Binary logistic regression analysis revealed that adolescents aged 15-19, adolescents with strong perceptions of parental conflict were at high risk of suicide intention. Adolescents living in rural areas, adolescents with high mother-child attachment, adolescents with high father-child attachment were at low risk of suicide intention. Furthermore, parent-child attachment played a mediating role between two dimensions of parental conflict perception (resolved situations and response effect) and suicide intention. Discussion: The study concludes that adolescents living in urban areas, older adolescents, adolescents with a high level of parental conflict intensity, and those with low levels of parent-child attachment are at high risk of suicide intention. parent-child attachment played a mediating role between two dimensions of parental conflict perception (resolved situations and response effect) and suicide intention. Interventions aimed at reducing family conflicts and improving parent-child relationships are recommended to decrease the incidence of adolescent suicide.

RESUMO

Introduction: Statistical data indicate a link between war and the spread of sexually transmitted infections (STIs), then it is necessary to carefully analyze the factors that directly affect the identified pattern in order to overcome this problem. Therefore, the purpose of the study was to systematically analyze the factors that influence the spread of STIs during war. Methods: The study included all original research articles and meta-analyses on the impact of war on the spread of sexually transmitted infections that met the following eligibility criteria: (1) articles published exclusively in English; (2) articles published in the period 2013-2023; (3) studies with quantitative, qualitative or mixed design. The search for relevant literature was conducted using four databases: PubMed, Embase, Web of Science, and Ebsco. Results: The articles selected for our systematic review had different research designs and were mainly published as original studies (n = 8) and literature reviews (n = 6). As a result of the evaluation of the selected articles for the systematic review, the authors identified migration, a decrease in access to health care, difficult access to contraception, sexual violence as the most frequent factors directly affecting the spread of STIs during the war. Conclusion: This systematic review systematizes data on the impact of hostilities on the spread of STIs and outlines the main factors that contribute to the dissemination of pathogens far beyond the territory at the epicenter of the conflict.Systematic review registration:https://www.crd.york.ac.uk/prospero/display_record.php?ID=CRD42023479808, CRD42023479808.

RESUMO

The military-industrial complex, military operations, and wars are major contributors to exacerbating both climate change and biodiversity crises. However, their environmental impacts are often shadowed due to national security reasons. The current paper aims to go through the devastating impacts of military operations and wars on climate change and biodiversity loss and challenges that hinder the inclusion of military-related activities into environmental crisis mitigation efforts. The information blind spot induced by concerns about national security reasons jeopardizes the efforts to involve the military-industrial complex and military operations in the global climate and biodiversity agendas. Besides that, many military-related challenges, such as specificity of operational requirements and lifecycles, dependence on fossil fuels, complex supply change, inadequate civilian technologies and innovations, and requirements of structural changes, can hinder emission reduction. Meanwhile, wars and conflicts not only threaten to drain all human and material resources available to tackle environmental problems but also inflict long-lasting destructions, pains, and trauma that can lead to hatred and distrust among nations and parties. With the rising hatred and distrust, global agreement and commitment to address climate change and biodiversity will hardly be achieved. Thus, promoting peace is the humanistic and planetary conscience.

RESUMO

Background: Robotic total knee arthroplasty (R-TKA) utilization and marketing continue to rise. We examined the marketing on surgeon websites regarding R-TKA benefits and sought to determine if the claims were supported by existing literature. Methods: A Google search identified 10 physician websites from each of the 5 largest U.S. markets by population with the term "robotic total knee arthroplasty city, state." Claims on websites about R-TKA were categorized. Literature from 2012-2022 was reviewed for data "for" or "against" each claim. Level of evidence for each publication was collected. Results: Fifty websites were captured that included 59 surgeons. A specific R-TKA platform was mentioned on 68% of websites. Website claims about robotics were placed into 8 major categories. Literature review supported the claims of more precise/accurate, reduced injury to tissue, and less pain with more literature "for" than "against" the claims. Conclusions: Claims made on physician websites regarding the benefits of R-TKA are variable and not definitively supported by existing literature. Most available data can be categorized into levels of evidence III, IV, and V. There is a paucity of level I evidence to support the various marketing statements. Physicians should be cognizant of both the claims made on their websites and the literature that could be used to support or refute those specific claims.

RESUMO

Conflict-based road safety assessments may provide a deeper insight into the processes leading to crashes compared to assessments solely based on field crash data. The evaluation of road safety is conducted on specific road segments using different surrogate measure of safety indicators, such as temporal, spatial, and kinematic proximity measures, depending on the relevant context and applicability of these measures. Therefore, this study endeavored to develop a methodology by adopting safety measures such as post encroachment time (PET) and conflicting speeds of through vehicles for crossing maneuvers and time to collision (TTC) for rear-end collisions at five unsignalized intersections in urban mixed traffic conditions. Critical conflicts are calculated by calculating a speed variable known as the critical speed, which is based on the braking distance. A study found that the motorized two wheeler (MTW) categories involve the highest proportion of critical conflict with right-turning vehicles, followed by cars, autos, and light commercial vehicle (LCVs). Furthermore, crossing conflicts were modeled as a function using the generalized linear regression approach. The findings revealed that the most significant factors were traffic volume and vehicular composition in a conflicting stream. The unsupervised classification technique k-mean clustering was used to determine the defined severity level threshold for rear-end maneuvers. The result observed was that a TTC threshold of less than 1.15 s was identified as high-risk vehicular interaction. Additional investigation indicated that presence of certain moving vehicle categories, including MTWs and cars, led to a higher proportion of critical crossing conflicts. The conceptualized safety framework can be applied to evaluate safety at unsignalized intersections in the mixed traffic scenarios.

RESUMO

The conflict in Gaza presents distinct difficulties that significantly impact the psychological well-being of healthcare workers (HCWs) making it imperative to understand and address their mental health needs in this specific context. This article highlights the unique challenges of the ongoing Gaza conflict and its critical impact on the mental health of HCWs. Observations in the paper revealed that HCWs in Gaza face extraordinary challenges, including the targeting of medical facilities, severe shortages of medical supplies, and the ethical dilemmas of providing care in such constrained conditions. These factors contribute to heightened stress, anxiety, and a pervasive sense of helplessness among HCWs. The paper also notes the compounded emotional burden due to the loss of colleagues and the need to navigate complex interactions with patients' families under extreme conditions. Furthermore, the lack of basic needs like adequate nutrition and safe drinking water for HCWs themselves further compromises their ability to provide care effectively, contributing further to worsened mental health. The paper also notes the lack of sufficient media coverage and support for these workers, contributing to a sense of isolation and neglect. HCWs in Gaza find themselves in a uniquely challenging situation, one that is marked not only by the immediate stresses of the ongoing conflict but also by the deep-seated psychological scars from past wars. The circumstances in Gaza are clinically relevant as they directly affect the HCWs' ability to provide care and maintain their well-being. These findings highlight the need for targeted mental health interventions and support tailored to the specific challenges faced by HCWs in Gaza. Addressing these issues is crucial for their well-being and ability to provide effective healthcare under such demanding and traumatic circumstances.

RESUMO

Background and Aim: Conflicts, akin to other crises, disrupt lives and healthcare infrastructure, disproportionately affecting vulnerable individuals. The ongoing Sudanese conflict, initiated on April 15, 2023, between the Sudanese Armed Forces (SAF) and the Rapid Support Force (RSF), triggers significant population displacement, healthcare facility closures, and a scarcity of medical resources. Amid the intense conflict in Khartoum, reports of deceased individuals in the streets heighten concerns about public health, emphasizing the gravity of the situation. This crisis compounds the challenges faced by Sudan's already fragile healthcare system, impacting over 5 million displaced individuals, including those reliant on life-saving hemodialysis sessions. This commentary aims to illuminate the challenges confronting kidney dialysis patients in war-torn Sudan, emphasizing the impact on the Al-Goled hemodialysis center. Methodology: This commentary relies on reports from the American Society of Nephrology (ASN), European Renal Association (ERA), and The International Society of Nephrology (ISN), along with recent journal articles discussing the consequences of ongoing conflicts. Personal observations in Al-Goled contribute to the insights, and data from the Al-Goled hemodialysis center in Sudan illuminate the struggles faced by kidney dialysis patients during the conflict, presented as a case study. Results: Kidney dialysis patients, crucial for regular hemodialysis sessions, confront severe challenges due to the overwhelming conflict. With an estimated 8000 kidney failure patients in Sudan, disruptions in healthcare services, targeted attacks on medical staff, and a shortage of resources exacerbate their plight. The Al-Goled hemodialysis center, initially designed for 30 daily sessions, experiences a surge in demand, accommodating 85 patients daily-an alarming 183% increase. Limited resources, machine malfunctions, and a shortage of medications contribute to the loss of 13 patients' lives. Conclusions: The conflict in Sudan disproportionately impacts kidney dialysis patients, causing disruptions in essential healthcare services. The surge in demand at the Al-Goled center underscores the broader impact on healthcare institutions nationwide. Local efforts to source medical supplies face bureaucratic hurdles and complex exportation procedures, impeding support for kidney patients. Patients, once receiving 3 weekly sessions, now struggle to secure even one, jeopardizing their well-being. Urgent international intervention is needed to cease the conflict and ensure the safety of healthcare facilities, especially for vulnerable populations like kidney dialysis patients.

RESUMO

Territorial space conflicts (TSCs) in coastal zones stem from the intricate interaction between the land-sea dual system, significantly impacting the sustainable development of these areas. To accurately identify TSCs, our study proposed a theoretical framework based on a land-sea interaction perspective. We also assessed TSCs using the territorial space conflicts index and a social network analysis model. We demonstrated the proposed spatial conflicts assessment methodology through a case study of Wenzhou, a typical city on the east coast of China. Our results indicate that the distribution of TSCs gradually decreased from the coastal zone to the inland zone, with significant variation in the distribution of different conflict types across different zones. The findings also reveal that territorial space use had diverse impacts on the space conflict network, making it urgent to take targeted measures. In the future, it is crucial to comprehensively consider the overall pattern and distribution characteristics of current TSCs, as well as the spatial spillover effect of the overall network, to develop targeted coping strategies and regulation mechanisms that promote the integration and high-quality development of coastal territorial space systems. To maintain a sustainable coastal zone process, we proposed a set of optimization paths for alleviating TSCs and promoting the coordinated development of land and sea regions in China based on our study.

RESUMO

Mobility and environmental benefits of Green Light Optimal Speed Advisory (GLOSA) systems have been reported by many previous research studies, however, there is insufficient knowledge on the safety implications of such an application. For safe deployment of GLOSA system, it is most critical to identify and address potential safety issues in the design process. It can be argued that implementation of GLOSA system can improve safety by reducing traffic conflicts associated with the interrupted traffic flow at signalised intersections. However, more research findings are needed from field and simulation based studies to evaluate the impacts on safety under a variety of real-world scenarios. As part of the LEVITATE (Societal Level Impacts of Connected and Automated Vehicles) project under European Union's Horizon 2020 Programme, the main objective of this study is to examine the safety impacts of GLOSA under mixed traffic compositions with varying market penetration rates (MPR) of connected and automated vehicles (CAVs). A calibrated and validated microsimulation model (developed in Aimsun) of the greater Manchester area was used for this study where three signalised intersections in a corridor were identified for implementing GLOSA system. An improved algorithm was developed by identifying the potential issues/limitations in some of the GLOSA algorithms found in literature. Behaviours of CAVs were modelled based on the findings of a comprehensive literature review. Safety analysis was performed through processing the simulated vehicular trajectories in the surrogate safety assessment model (SSAM) by the Federal Highway Administration (FHWA). The surrogate safety assessment results showed small improvement in safety with the GLOSA implementation at multiple intersections in the test network only at low MPR (20%) scenarios of CAVs, as compared to the respective without GLOSA scenarios. No or rather slightly lower improvement in safety was observed with GLOSA implementation under mixed fleet scenarios with 40 % or higher 1st Generation or 2nd Generation CAVs, as compared to the respective scenarios without GLOSA. The implementation of GLOSA system was also found to have some impact on the traffic conflict types (although not consistent across all MPR scenarios), where rear-end conflicts were found to decrease while a slight increase was observed in lane-change conflicts.

RESUMO

Although climate change has convincingly been linked to the evolution of human civilization on different temporal scales, its role in influencing the spatial patterns of ancient civilizations has rarely been investigated. The northward shift of the ancient Silk Road (SR) route from the Tarim Basin (TB) to the Junggar Basin during ∼420-850 CE provides the opportunity to investigate the relationship between climate change and the spatial evolution of human societies. Here, we use a new high-resolution chironomid-based temperature reconstruction from arid China, combined with hydroclimatic and historical datasets, to assess the possible effects of climate fluctuations on the shift of the ancient SR route. We found that a cooling/drying climate in the TB triggered the SR route shift during ∼420-600 CE. However, a warming/wetting climate during ∼600-850 CE did not inhibit this shift, but instead promoted it, because of the favorable climate-induced geopolitical conflicts between the Tubo Kingdom and the Tang Dynasty in the TB. Our findings reveal two distinct ways in which climate change drove the spatial evolution of human civilization, and they demonstrate the flexibility of societal responses to climate change.

RESUMO

While socioeconomic and institutional factors are crucial in explaining the onset and evolution of conflicts, recent research suggests that climate change is a further indirect driver acting as a "threat multiplier". This paper focuses on the concept of vulnerability to both climate change and conflicts to explain why some locations are more likely to engage in armed conflicts than others in the presence of a similar level of exposure to climatic changes. In particular, by means of a Spatial Autoregressive Model, we identify a set of local-specific vulnerability factors that increase conflict risk in East Africa. We employ a georeferenced database with a resolution of 25 × 25 km, covering the period 1997-2016. Results from our analysis provide some interesting insights: first, climate change does not increase conflict risk per se, but only in the presence of pre-existing vulnerabilities. Second, resource access and socioeconomic factors play a key role in driving the climate-conflict nexus especially in urban areas. In particular, vulnerability is increased whenever power is not distributed in such a way as to ensure an equitable distribution of resources. Overall, our findings suggest that, by addressing vulnerability factors that prevent adaptive capacity and an equitable distribution of resources, societies may benefit in terms of both diminished conflict risk and alleviation of climate change impacts.
