Meta-análisis: Intervalos de confianza e Intervalos de predicción / Meta-analysis: Confidence intervals and Prediction intervals

En los informes meta-analíticos se suelen reportar varios tipos de intervalos, hecho que ha generado cierta confusión a la hora de interpretarlos. Los intervalos de confianza reflejan la incertidumbre relacionada con un número, el tamaño del efecto medio paramétrico. Los intervalos de predicción reflejan el tamaño paramétrico probable en cualquier estudio de la misma clase que los incluidos en un meta-análisis. Su interpretación y aplicaciones son diferentes. En este artículo explicamos su diferente naturaleza y cómo se pueden utilizar para responder preguntas específicas. Se incluyen ejemplos numéricos, así como su cálculo con el paquete metafor en R.(AU)

Several types of intervals are usually employed in meta-analysis, a fact that has generated some confusion when interpreting them. Confidence intervals reflect the uncertainty related to a single number, the parametric mean effect size. Prediction intervals reflect the probable parametric effect size in any study of the same class as those included in a meta-analysis. Its interpretation and applications are different. In this article we explain in de-tail their different nature and how they can be used to answer specific ques-tions. Numerical examples are included, as well as their computation with the metafor Rpackage.(AU)

Using comparative extinction risk analysis to prioritize the IUCN Red List reassessments of amphibians.

Assessing the extinction risk of species based on the International Union for Conservation of Nature (IUCN) Red List (RL) is key to guiding conservation policies and reducing biodiversity loss. This process is resource demanding, however, and requires continuous updating, which becomes increasingly difficult as new species are added to the RL. Automatic methods, such as comparative analyses used to predict species RL category, can be an efficient alternative to keep assessments up to date. Using amphibians as a study group, we predicted which species are more likely to change their RL category and thus should be prioritized for reassessment. We used species biological traits, environmental variables, and proxies of climate and land-use change as predictors of RL category. We produced an ensemble prediction of IUCN RL category for each species by combining 4 different model algorithms: cumulative link models, phylogenetic generalized least squares, random forests, and neural networks. By comparing RL categories with the ensemble prediction and accounting for uncertainty among model algorithms, we identified species that should be prioritized for future reassessment based on the mismatch between predicted and observed values. The most important predicting variables across models were species' range size and spatial configuration of the range, biological traits, climate change, and land-use change. We compared our proposed prioritization index and the predicted RL changes with independent IUCN RL reassessments and found high performance of both the prioritization and the predicted directionality of changes in RL categories. Ensemble modeling of RL category is a promising tool for prioritizing species for reassessment while accounting for models' uncertainty. This approach is broadly applicable to all taxa on the IUCN RL and to regional and national assessments and may improve allocation of the limited human and economic resources available to maintain an up-to-date IUCN RL.

Uso del análisis comparativo del riesgo de extinción para priorizar la reevaluación de los anfibios en la Lista Roja de la UICN Resumen El análisis del riesgo de extinción de una especie con base en la Lista Roja (LR) de la Unión Internacional para la Conservación de la Naturaleza (UICN) es clave para guiar las políticas de conservación y reducir la pérdida de la biodiversidad. Sin embargo, este proceso demanda recursos y requiere de actualizaciones continuas, lo que se complica conforme se añaden especies nuevas a la LR. Los métodos automáticos, como los análisis comparativos usados para predecir la categoría de la especie en la LR, pueden ser una alternativa eficiente para mantener actualizados los análisis. Usamos a los anfibios como grupo de estudio para predecir cuáles especies tienen mayor probabilidad de cambiar de categoría en la LR y que, por lo tanto, se debería priorizar su reevaluación. Usamos las características biológicas de la especie, las variables ambientales e indicadores climáticos y del cambio de uso de suelo como predictores de la categoría en la LR. Elaboramos una predicción de ensamble de la categoría en la LR de la UICN para cada especie mediante la combinación de cuatro algoritmos diferentes: modelos de vínculo acumulativo, menor número de cuadros filogenéticos generalizados, bosques aleatorios y redes neurales. Con la comparación entre las categorías de la LR y la predicción de ensamble y con considerar la incertidumbre entre los algoritmos identificamos especies que deberían ser prioridad para futuras reevaluaciones con base en el desfase entre los valores predichos y los observados. Las variables de predicción más importantes entre los modelos fueron el tamaño de la distribución de la especie y su configuración espacial, las características biológicas, el cambio climático y el cambio de uso de suelo. Comparamos nuestra propuesta de índice de priorización y los cambios predichos en la LR con las reevaluaciones independientes de la LR de la UICN y descubrimos un buen desempeño tanto para la priorización como para la direccionalidad predicha de los cambios en las categorías de la LR. El modelo de ensamble de la categoría de la LR esa una herramienta prometedora para priorizar la reevaluación de las especies a la vez que considera la incertidumbre del modelo. Esta estrategia puede generalizarse para aplicarse a todos los taxones de la LR de la UICN y a los análisis regionales y nacionales. También podría mejorar la asignación de los recursos humanos y económicos limitados disponibles para mantener actualizada la LR de la UICN.

Adverse childhood experiences of Korean mothers with young children: a latent class analysis.

Background: Adverse childhood experiences (ACEs) have negative impacts on women with children, including psychosocial and general health problems. However, there is limited research investigating ACEs identifying the characteristics of distinct subgroups according to the frequency of ACEs.Objective: Utilizing the national dataset of the Family with Children Life Experience 2017, this study aimed to classify patterns of ACEs based on the total number of types of ACEs and the types of predominant events, and to examine differences in general and psychological characteristics, as well as experiences of violence in adulthood among the classes identified.Method: A total of 460 Korean mothers raising infants or toddlers participated. Latent class analysis was performed to classify the patterns of ACEs, while t-tests and Chi-square tests were used to examine differences in general and psychological characteristics and experiences of violence between the ACEs subgroups.Results: The participants were classified into two subgroups: the 'high-ACEs group' and the 'low-ACEs group'. The high-ACEs group exhibited higher rates of child abuse, workplace violence perpetration and victimization, as well as lower self-esteem, higher depression levels, and increased suicidal thoughts compared to those of the low-ACEs group.Conclusion: The findings highlight the significant role of ACEs on the formation of an individual's psychological characteristics and their propensity to experience additional violence even into adulthood, as perpetrators and as victims. It is noteworthy how the influence of ACEs extends across generations through child abuse. These findings offer insights for developing interventions aimed at mitigating the negative effects of experiences of violence on mothers raising young children.

Two distinct subgroups were identified according to the frequency of ACEs: the 'high-ACEs group' and the 'low-ACEs group'.Compared to those of the low-ACEs group, the high-ACEs group presented higher rates of child abuse, workplace violence perpetration and victimization, lower self-esteem, higher depression levels, and increased suicidal thoughts.The low self-esteem induced by ACEs may contribute to the amplification of psychological vulnerabilities and the occurrence of additional violent experiences even in adulthood.

A network perspective on posttraumatic stress disorder and comorbid borderline personality disorder symptoms.

Background: Comorbidity between posttraumatic stress disorder (PTSD) and borderline personality disorder (BPD) is surrounded by diagnostic controversy and although various effective treatments exist, dropout and nonresponse are high.Objective: By estimating the network structure of comorbid PTSD and BPD symptoms, the current study illustrates how the network perspective offers tools to tackle these challenges.Method: The sample comprised of 154 patients with a PTSD diagnosis and BPD symptoms, assessed by clinician-administered interviews. A regularised partial correlation network was estimated using the GLASSO algorithm in R. Central symptoms and bridge symptoms were identified. The reliability and accuracy of network parameters were determined through bootstrapping analyses.Results: PTSD and BPD symptoms largely clustered into separate communities. Intrusive memories, physiological cue reactivity and loss of interest were the most central symptoms, whereas amnesia and suicidal behaviour were least central.Conclusions: Present findings suggest that PTSD and BPD are two distinct, albeit weakly connected disorders. Treatment of the most central symptoms could lead to an overall deactivation of the network, while isolated symptoms would need more specific attention during therapy. Further experimental, longitudinal research is needed to confirm these hypotheses.Trial registration: ClinicalTrials.gov identifier: NCT03833453.

A network analysis of PTSD and BPD symptoms.PTSD and BPD symptoms largely clustered into separate communities.Intrusive memories, loss of interest and physiological cue reactivity seem valuable treatment targets.

Moral injury appraisals and posttraumatic stress symptoms in trauma-exposed police officers: a latent class analysis.

Background: Police officers encounter various potentially traumatic events (PTEs) and may be compelled to engage in actions that contradict their moral codes. Consequently, they are at risk to develop symptoms of Posttraumatic Stress Disorder (PTSD), but also moral stress or moral injury (MI). To date, MI in police officers has received limited attention.Objective: The present study sought to identify classes of MI appraisals and PTSD symptoms among police officers exposed to PTEs, while also investigating potential clinical differences between these classes.Method: For this study, 421 trauma-exposed police officers were assessed on demographics and several clinical measurements including MI appraisals (self-directed and other-directed), PTSD severity, and general psychopathology. Latent class and regression analyses were conducted to examine the presence of different classes among trauma-exposed police officers and class differentiation in terms of demographics, general psychopathology, PTSD severity, mistrust, guilt, self-punishment, and feelings of worthlessness.Results: The following five classes were identified: (1) a 'Low MI, high PTSD class' (28%), (2) a 'High MI, low PTSD class' (11%), (3) a 'High MI, high PTSD class' (17%), (4) a 'Low MI, low PTSD class' (16%), and (5) a 'High MI-other, high PTSD class' (27%). There were significant differences between the classes in terms of age, general psychopathology, PTSD severity, mistrust, guilt, and self-punishment but no differences for gender and feelings of worthlessness.Conclusion: In conclusion, we identified five classes, each exhibiting unique patterns of cognitive MI appraisals and PTSD symptoms. This underscores the criticality of measuring and identifying MI in this particular group, as it allows for tailored treatment interventions.

This study identified classes differing in terms of endorsement of MI appraisals and posttraumatic stress disorder (PTSD) symptoms among police officers exposed to potentially traumatic events.Five classes were identified, each exhibiting unique patterns of MI appraisals and PTSD symptoms.It is important to measure the presence of MI appraisals in addition to PTSD symptoms in traumatized police officers as it can inform treatment interventions.

Validación de test de flexión-relajación para definir un déficit lumbar con electrodos tetrapolares / Validation of the flexion-relaxation test to define a lumbar deficit with tetrapolar electrodes

Introducción y objetivo: Obtener un nuevo punto de corte (PC) para un test de flexión-relajación (FR) lumbar efectuado con electrodos (e.) tetrapolares, desde valores ya definidos con dispositivos bipolares.Materiales y métodosLa muestra del estudio consta de 47 pacientes en situación de incapacidad temporal por dolor lumbar (DL). Fueron evaluados mediante un test de dinamometría isométrica, una prueba cinemática y una valoración del fenómeno FR.Se plantean dos experimentos con curvas ROC. El primero, con 47 pacientes que efectuaron de modo consecutivo el test FR con ambos tipos de electrodos, utilizándose como variable de clasificación el punto de corte conocido para los e. bipolares (2,49uV). En el segundo, con los datos de la EMGs registrados con e. tetrapolares en 17 pacientes, se efectúa un test de DeLong que compara las 2 curvas ROC que construimos, por un lado, al clasificar la muestra desde pruebas de dinamometría y cinemática, y por el otro, al clasificarlos con los valores de la EMGs bipolar.ResultadosUn total de 34 pacientes completaron adecuadamente las valoraciones del primer experimento y 17 pacientes el segundo. El primer estudio arroja un punto de corte de 1,2uV, con un AUC del 87,7%; sensibilidad 84,2% y especificidad 80%. El segundo muestra un PC para los e. bipolares de 1,21uV (AUC 87,5%) y para los e. tetrapolares de 1,43 (AUC 82,5%) con un test de DeLong sin diferencias significativas entre ambas curvas (p>0,4065).ConclusionesLa metodología de validación con curvas ROC ha permitido obtener un nuevo PC para la prueba FR de modo práctico, simplemente simultaneando ambos test sobre el mismo grupo de pacientes hasta obtener una muestra significativa.

Introduction and objective: To obtain a new cut-off point (CP) for a lumbar flexion-relaxation (RF) test established with tetrapolar (e.) electrodes, from values already defined with bipolar devices.Materials and methodsThe study sample consists of 47 patients in a situation of temporary disability due to low back pain (DL). They were evaluated by means of an isometric dynamometry test, a kinematic test and an assessment of the FR phenomenon.Two experiments with ROC curves are proposed. The first, with 47 patients who consecutively performed the RF test with both types of electrodes, using the cut-off point (CP) known for the e. bipolar (2.49μV). In the second, with the EMG data recorded with e. tetrapolar in 17 patients, a DeLong test was performed that compares the 2 ROC curves that were constructed on the one hand, by classifying the sample from dynamometry and kinematic tests, and on the other, by classifying them with the bipolar EMG values.ResultsA total of 34 patients adequately completed the evaluations of the first experiment and 17 patients the second. The first study shows a cut-off point of 1.2μV, with an AUC of 87.7%; Sensitivity 84.2% and Specificity 80%. The second shows a PC for e. bipolars of 1.21μV (AUC 87.5%) and for e. tetrapolar values of 1.43 (AUC 82.5%) with a DeLong test without significant differences between both curves (p>0.4065).ConclusionsThe validation methodology with ROC curves has made it possible to obtain a new PC for the RF test in a practical way, simply by simultaneously performing both tests on the same group of patients until a significant sample is obtained.

Identification, spatial distribution, and associated factors of urban protected areas in China.

The increasing proximity between protected areas (PAs) and urban areas, which can lead to urban protected areas (UPAs), is now commonplace. Use of Euclidean distance to measure the distance between PAs and cities has not correctly portrayed the spatial relationship between PAs and cities. We devised an isochronous circle model to accurately measure the distance between 2706 national PAs in 5 categories and 2844 cities in China based on human accessibility to identify urban human activity-influenced protected areas (UHAIPAs) and to quantitatively analyze their distribution patterns and relationships with China's economy, population distribution patterns, and urban development indicators. Most of the PAs in China were established near cities. Of 2746 PAs in China, 18.35% (n = 504) became UPAs, and 58.27% (n = 1600), 16.72% (n = 459), and 3.31% (n = 91) of PAs were within 0-30, 30-60, and 60-90 min, respectively. Both UPAs and UHAIPAs in China in general exhibited obvious spatial aggregation characteristics (e.g., wetland parks and scenic areas), and there was a significant spatial dependence effect among characteristics. The degree of spatial distribution and aggregation of UPAs was correlated with 16 indicators across urban economic development, urban natural substrate, and urban policy support factors. Based on the results of our study, we call for various governments and scholars to focus on areas where wetland parks and PAs overlap with urban boundaries. It is important to emphasize the potential link between the development of agriculture, forestry, livestock and fisheries industries, and UPAs. Overall, we believe that examining the accessibility of PAs can more accurately measure the distance between PAs and cities, and more realistically reflect the possible impacts of urban human activities on PAs, which is helpful for strengthening the conservation and management of PAs.

Identificación, distribución espacial y factores asociados de las áreas urbanas protegidas en China Resumen La creciente proximidad entre las áreas protegidas (AP) y las áreas urbanas, que puede derivar en áreas urbanas protegidas (AUP), es muy común hoy en día. La distancia euclidiana no ha representado correctamente la distancia entre las AP y las ciudades. Por lo anterior, diseñamos un modelo de círculo isócrono para medir con certeza la distancia entre 2706 AP nacionales en cinco categorías y 2844 ciudades de China con base en la accesibilidad humana para identificar las áreas urbanas protegidas con influencia de actividad humana (AUPIAH). También lo usamos para analizar cuantitativamente los patrones de distribución y su relación con la economía china, los patrones de distribución poblacional y los indicadores de desarrollo urbano. La mayoría de las AP en China están establecidas cerca de las ciudades. De las 2746 AP, el 18.35% (n = 504) se convirtieron en AUP y el 58.27% (n = 1600), 16.72% (n = 459) y 3.31% (n = 91) se encontraban de 0­30 minutos, 30­60 y de 60­90 minutos de una ciudad, respectivamente. Tanto las AUP y las AUPIAH exhibieron características obvias de agregación espacial (p. ej.: parques de humedales y áreas escénicas) y hubo un efecto significativo de dependencia espacial entre dichas características. El nivel de distribución y agregación espacial de las AUP tuvo correlación con 16 indicadores de desarrollo económico urbano, sustrato natural urbano y factores de apoyo para las políticas urbanas. Con base en los resultados de nuestro estudio, hacemos un llamado para que diferentes gobiernos y académicos se enfoquen en las áreas en donde se traslapan las AP y los parques de humedales con los límites urbanos. Es importante resaltar la conexión potencial entre el desarrollo de la agricultura, silvicultura, ganadería y pesquería y las AUP. En general, consideramos que analizar la accesibilidad de las AP puede medir de forma más certera la distancia entre las AP y las ciudades, además de que refleja de forma más realista el posible impacto de las actividades humanas sobre las AP, lo cual es útil para fortalecer la conservación y gestión de las AP.

Combined effect of compassionate and uncompassionate self-responding on Chinese college students' mental health during the initial wave of the COVID-19 pandemic: a response surface analysis.

Background: The initial wave of the COVID-19 pandemic significantly deteriorated mental health, especially among college students. Self-compassion has demonstrated benefits for psychological outcomes such as depressive symptoms, life satisfaction, posttraumatic stress symptoms (PTSS), and posttraumatic growth (PTG). Notably, existing literature suggests that the protective and vulnerable aspects within the Self-Compassion Scale, namely, compassionate and uncompassionate self-responding (CSR and USR), can coexist within individuals and influence their mental health through various coexisting patterns. However, this process has not been sufficiently explored.Objective: This study aimed to explore the combined effects of CSR and USR on college students' depressive symptoms, life satisfaction, PTSS, and PTG during the initial wave of the pandemic.Method: In this cross-sectional study, 4450 Chinese college students (51.9% females, Mage = 20.58 years, SD = 1.49) completed self-report measures amid the COVID-19 pandemic's initial wave in 2020. Response surface analyses were utilised to investigate the combined effects of CSR and USR.Results: Simultaneously increased CSR and USR were associated with a slight increase in depressive symptoms, PTSS, and life satisfaction, but a substantial increase in PTG. Conversely, increased CSR and decreased USR were associated with a considerable decrease in depressive symptoms and PTSS, a significant increase in life satisfaction, and a moderate increase in PTG.Conclusions: CSR and USR demonstrated protective and vulnerable impacts, respectively. It is imperative to analyse their combined effects as an interactive system and consider the specific characteristics of different psychological responses.

Increased CSR and decreased USR were associated with less depressive symptoms and PTSS as well as more life satisfaction.CSR mitigated the negative effects of USR on depressive symptoms, life satisfaction, and PTSS.Simultaneously increased CSR and USR were associated with a substantial increase in PTG.

The utility of 18F-FDG-PET/CT in detecting extracranial large vessel vasculitis in rheumatic polymyalgia or giant cell arteritis. A systematic review and meta-analysis.

OBJECTIVE: Systematic review of current evidence to analyze the prevalence of extracranial large vessel vasculitis (LVV) using 18F-FDG PET/CT in patients with polymyalgia rheumatica (PMR) or giant cell arteritis (GCA). MATERIALS AND METHODS: PubMed and EMBASE were searched and the results were screened by two reviewers. Study quality was assessed using a modified version of the Newcastle-Ottawa scale. Heterogeneity between studies was assessed using the I2 statistic and the Q test. Further subgroup analyses were performed by disease type, study quality, and 18F-FDG PET/CT uptake criteria. Publication bias was assessed by funnel plot and Egger's test. RESULTS: 268 publications were identified, of which 17 met the selection criteria and were included in the meta-analysis. The overall pooled prevalence of extracranial LVV by 18F-FDG PET/CT was 54.5% [95% CI: 42.6%-66.1%]. In patients with GCA the prevalence was significantly higher than in patients with PMR (60.1% vs. 41.8%, P = 0.006). Likewise, studies with a lower risk of bias reported a higher prevalence of extracranial LVV (61.1% vs. 46.9%; P = 0.010). No publication bias was observed. CONCLUSIONS: The 18F-FDG PET/CT test may be useful in the detection of extracranial LVV, both in patients with PMR or GCA. Such involvement is more frequent in patients with GCA, and may vary depending on the quality of the studies.

Rising testicular cancer incidence in Spain despite declining mortality: an age-period-cohort analysis.

BACKGROUND: Testicular cancer, primarily affecting young men, has seen an alarming rise globally. This study delves into incidence and mortality trends in Spain from 1990 to 2019 using the Global Burden of Disease (GBD) database and the Age-Period-Cohort (A-P-C) model. METHODS: We analyzed GBD data on testicular cancer cases and deaths in Spain, calculating age-standardized rates (ASIR and ASMR) and employing Joinpoint regression to identify significant shifts. The A-P-C model further dissected the effects of age, period, and birth cohort on these trends. RESULTS: A striking doubling in testicular cancer incidence was observed, from 3.09 to 5.40 per 100,000 men (1.9% annual increase), while mortality rates remained stable and even decreased in younger age groups (0.34 to 0.26 per 100,000, 0.8% annual decrease). Joinpoint analysis revealed four distinct periods of increasing incidence, with a recent slowdown. The A-P-C model highlighted a consistent rise in incidence risk with each successive generation born after 1935, contrasting with a progressive decline in mortality risk across cohorts, particularly marked for those born since the 1960s. CONCLUSION: While mortality rates are encouraging, Spain reflects the global trend of escalating testicular cancer incidence. The A-P-C analysis suggests a generational influence, but the underlying causes remain elusive. Further research is crucial to understand these trends and implement effective prevention strategies to combat this growing health concern.

Violence Exposure and Disability in Colombian Female Survivors of Intimate Partner Violence: the Mediating Role of Depressive Symptoms.

BACKGROUND: Violence is an important public health problem and one of the main causes of deaths worldwide. The mental health consequences of surviving intimate partner violence (IPV) include depression, anxiety and post-traumatic stress disorder. Previous studies have identified that there is a relationship between depression and level of disability in female survivors of IPV. Estimating the direct, indirect or total effect of an exposure on an outcome makes it possible to identify mediating effects between a group of variables. Detecting mediation effects is useful for identifying casual pathways that generate a final outcome and provides a rationale for designing interventions to target the mediator, which in turn positively affects the outcome. The objective was to identify the mediating role of depressive symptoms on the relationship between IPV and disability. METHODS: This was a cross-sectional study of 94 women over the age of 18 who were survivors of IPV by men. They were recruited from two public hospitals in Cali and Tuluá in southwest Colombia. An analysis of casual relationships was performed using structural equation modelling that was made up of: four exogenous observed variables (age, current relationship status [in a relationship or single], level of schooling, and history of an impairment), intermediate endogenous variables (violence and depressive symptoms), and the main endogenous variable (disability). The analyses were carried out in Stata14.2. RESULTS: The direct effect of IPV severity on the level of disability was not statistically significant (ß=0.09; P=0.63). However, the indirect effect of IPV severity on disability mediated by depressive symptoms was (ß=0.39; P<0.01). The total effect of IPV severity on the level of disability was even greater (ß=0.48; P=0.01). CONCLUSIONS: This study found a complete mediating role of depressive symptoms on the relationship between the severity of IPV and the level of disability for the female participants in this study. The results of this research contribute to defining strategies to prevent and address intimate partner violence, depressive symptoms and disability in this population.

Analysis to retreatment with monoclonal antibodies in chronic/episodic migraine: Real world data. / [Artículo traducido] Análisis del retratamiento con anticuerpos monoclonales en la migraña crónica/episódica: datos en vida real.

OBJECTIVE: To analyze the response to retreatment in patients with chronic/episodic migraine who discontinued therapy with erenumab/fremanezumab after one year of treatment. METHODS: Observational, retrospective, single-center, multidisciplinary study in patients with chronic/episodic migraine who received therapy with erenumab/fremanezumab for at least one year and discontinued it after achieving an adequate response (optimization). The evaluation of the response after retreatment included the following variables: migraine days per month, MIDAS and HIT-6 scales at the beginning of retreatment and 3 months later. The response was evaluated in different subgroups (episodic/chronic, erenumab/fremanezumab and time until retreatment). RESULTS: 48 patients were included. 70.8% (n=34) required retreatment with mAb, with a median of 3.9 (2.9-6.4) months until reintroduction. Clinical response after retreatment was achieved in 67.6% (n=23) of patients. No statistically significant differences were found in the analyzed subgroups. CONCLUSION: Interruption of treatment with erenumab/fremanezumab for chronic/episodic migraine produces a clinical worsening of the disease requiring retreatment in most cases, approximately after 4 months. Two out of three patients respond positively after restarting monoclonal therapy.

Identifying post-traumatic stress symptom typologies in clinical and non-clinical healthcare staff: a latent profile analysis.

Background: There has been growing concern regarding increasing levels of post-traumatic stress (PTS) symptoms experienced by healthcare workers (HCW) in the UK, particularly following the COVID-19 pandemic.Objectives: PTS symptom typologies have been investigated in other adult populations using person-centred latent variable approaches, revealing profiles showing differing symptom levels and patterns. We aimed to explore typologies among clinical and non-clinical healthcare staff to elucidate heterogeneity of presentation.  Methods: This was a retrospective study using referral data from treatment-seeking healthcare staff in the North of England (N = 1600). We employed latent profile analysis using the PTSD International Trauma Questionnaire domains as profile indicators. We included covariates relating to role-type, depression, anxiety and mental health concerns before March of 2020.   Results: A model with six profiles fit the data best. Profile names were given as follows: 'No symptom'; 'Low symptom'; 'Low symptom (moderate Sense of current threat (Th_dx) and Functional impairment (FI))'; 'Moderate symptom (low Th_dx and high Avoidance (Av_dx))'; 'Moderate symptom'; and 'High symptom'. Covariates were shown to have differential predictive power on profile membership. Conclusions: The finding of profiles with pattern differences suggests a need for both differential and specifically targeted treatments, as well as a consideration of early intervention for those individuals with subclinical PTS symptoms. As expected, anxiety and depression were both predictors of several of the symptomatic profiles, with anxiety producing a larger effect. Further research is required to fully understand the link between role-type and PTS symptom typologies among HCW. .

Six distinct profiles of post-traumatic stress symptoms were found in treatment-seeking healthcare staff.Four of the profiles differed only in terms of severity of symptoms. Two of the profiles revealed pattern differences relating to differing severity across avoidance, sense of current threat and functional impairment.Working in a non-clinical role (e.g. hospital porter or admin staff) predicted membership of two of the moderate symptom profiles.Other mental health difficulties, anxiety and depression, predicted membership of several symptomatic profiles.

Complex posttraumatic stress disorder and dissociation in trauma-exposed Chinese adolescents: a latent class analysis.

Background: Preliminary evidence provides support for the proposition that there is a dissociative subtype of Complex posttraumatic stress disorder (CPTSD). Research on this proposition would extend our knowledge on the association between CPTSD and dissociation, guide contemporary thinking regarding placement of dissociation in the nosology of CPTSD, and inform clinically useful assessment and intervention.Objectives: The present study aimed to investigate the co-occurring patterns of CPTSD and dissociative symptoms in a large sample of trauma exposed adolescents from China, and specify clinical features covariates of such patterns including childhood trauma, comorbidities with major depressive disorder (MDD) and generalized anxiety disorder (GAD), and functional impairment.Methods: Participants included 57,984 high school students exposed to the coronavirus disease 2019 (COVID-19) pandemic. CPTSD and dissociative symptoms, childhood traumatic experience, and functional impairment were measured with the Global Psychotrauma Screen for Teenagers (GPS-T). Major depressive disorder (MDD) and generalized anxiety disorder (GAD) symptoms were measured with the Patient Health Questionnaire-9 (PHQ-9) and the Generalized Anxiety Disorder-7 (GAD-7), respectively. Latent class analysis (LCA) was employed to test the co-occurring patterns of CPTSD and dissociative symptoms. Analysis of covariance (ANCOVA) and chi-square tests were respectively used to examine between-class differences in continuous and categorical clinical covariates.Results: A 5-class model emerged as the best-fitting model, including resilience, predominantly PTSD symptoms, predominantly disturbances in self-organization (DSO)symptoms, predominantly CPTSD symptoms, and CPTSD dissociative subtype classes. The CPTSD dissociative subtype class showed the lowest level of functioning and the highest rates of MDD, GAD and childhood trauma.Conclusions: Our findings provide initial empirical evidence supporting the existence of a dissociative subtype of CPTSD, and inform for further research and clinical practice on traumatized individuals.

The present study identified a dissociative subtype of ICD-11 CPTSD among trauma exposed youth.The dissociative subtype of ICD-11 CPTSD was associated with poorer mental health outcomes.Findings of this study provide initial empirical evidence supporting the existence of a dissociative subtype of CPTSD.

Reframing wildlife disease management problems with decision analysis.

Contemporary wildlife disease management is complex because managers need to respond to a wide range of stakeholders, multiple uncertainties, and difficult trade-offs that characterize the interconnected challenges of today. Despite general acknowledgment of these complexities, managing wildlife disease tends to be framed as a scientific problem, in which the major challenge is lack of knowledge. The complex and multifactorial process of decision-making is collapsed into a scientific endeavor to reduce uncertainty. As a result, contemporary decision-making may be oversimplified, rely on simple heuristics, and fail to account for the broader legal, social, and economic context in which the decisions are made. Concurrently, scientific research on wildlife disease may be distant from this decision context, resulting in information that may not be directly relevant to the pertinent management questions. We propose reframing wildlife disease management challenges as decision problems and addressing them with decision analytical tools to divide the complex problems into more cognitively manageable elements. In particular, structured decision-making has the potential to improve the quality, rigor, and transparency of decisions about wildlife disease in a variety of systems. Examples of management of severe acute respiratory syndrome coronavirus 2, white-nose syndrome, avian influenza, and chytridiomycosis illustrate the most common impediments to decision-making, including competing objectives, risks, prediction uncertainty, and limited resources.

Replanteamiento del manejo de problemas por enfermedades de fauna mediante el análisis de decisiones Resumen El manejo actual de las enfermedades de la fauna es complejo debido a que los gestores necesitan responder a una amplia gama de actores, varias incertidumbres y compensaciones difíciles que caracterizan los retos interconectados del día de hoy. A pesar de que en general se reconocen estas complejidades, el manejo de las enfermedades tiende a plantearse como un problema científico en el que el principal obstáculo es la falta de conocimiento. El proceso complejo y multifactorial de la toma decisiones está colapsado dentro de un esfuerzo científico para reducir la incertidumbre. Como resultado de esto, las decisiones contemporáneas pueden estar simplificadas en exceso, depender de métodos heurísticos simples y no considerar el contexto legal, social y económico más amplio en el que se toman las decisiones. De manera paralela, las investigaciones científicas sobre las enfermedades de la fauna pueden estar lejos de este contexto de decisiones, lo que deriva en información que puede no ser directamente relevante para las preguntas pertinentes de manejo. Proponemos replantear los obstáculos para el manejo de enfermedades de fauna como problemas de decisión y abordarlos con herramientas analíticas de decisión para dividir los problemas complejos en elementos más manejables de manera cognitiva. En particular, las decisiones estructuradas tienen el potencial de mejorar la calidad, el rigor y la transparencia de las decisiones sobre las enfermedades de la fauna en una variedad de sistemas. Ejemplos como el manejo del coronavirus del síndrome de respiración agudo tipo 2, el síndrome de nariz blanca, la influenza aviar y la quitridiomicosis ilustran los impedimentos más comunes para la toma de decisiones, incluyendo los objetivos en competencia, riesgos, incertidumbre en las predicciones y recursos limitados.

Female authorship positions in health economic evaluations: a cross-sectional analysis.

OBJECTIVE: To investigate the gender of the authors who publish articles of health economic evaluations in medicine and healthcare journals. METHOD: We evaluated a random sample of economic evaluations indexed in MEDLINE during 2019. Gender of the first, last and corresponding author was determined by review of the author's first name. Data were summarized as frequency and percentage for categorical items and median and interquartile range (IQR) for continuous items. We also calculated the index of authors per paper. RESULTS: We included 200 studies with 1365 authors (median of 6 authors per paper; IQR: 4-9). Gender identification was possible for all authors in the study sample: 802 (59%) were men and 563 (41%) were women. The number of female first, last, and corresponding authors respectively were 78 (39%), 68 (34%), and 80 (40%) for health economic evaluations. DISCUSSION: Female scientists were underrepresented as co-authors and in prominent authorship positions in health economic evaluations. This study serves as a call to action for the scientific community to actively work towards equity and inclusion.

Expression and Clinical Significance of CLCA2 in Pan-Cancer

SUMMARY: The calcium-activated chloride channel (CLCA2) performs a vital function in the intricate process of tumorigenesis. Using a bioinformatics analysis system, we conducted a pan-cancer investigation on CLCA2 to explore its association with tumor prognosis and its involvement in immunology. In order to achieve this objective, we examined the prognostic significance and expression level of CLCA2 in multiple cancer types using the TIMER and Sangerbox databases. The analysis of protein interaction networks revealed proteins linked to CLCA2. To investigate the potential biological functions and enrichment pathways of CLCA2 in cancer, the SangerBox and GSCA databases were utilized. Furthermore, the expression of CLCA2 in different cancer subtypes was evaluated during the analysis. Various functional conditions of cancer cells were then compared with CLCA2 in the CancerSEA database. Using online tools like TISIDB and Assistant for Clinical Bioinformatics, the investigation explored the link between CLCA2 and immune subtypes. Additionally, it assessed immune cell infiltration as part of the analysis. In addition, the application of GDSA was employed to investigate the predictive significance of CLCA2 in relation to drug sensitivity. The research outcomes uncovered abnormal expression patterns of CLCA2 in diverse tumor categories, with its expression level demonstrating a correlation with distinct subtypes of tumors. Strong associations have been observed between enhanced patient survival rates and CLCA2 in specific tumor types. There is a noteworthy connection observed among diverse tumor types, immune cell infiltration, immune subtypes, and CLCA2. The enrichment analysis of KEGG indicates that there may exist a connection between the expression of CLCA2 and renin secretion, pancreatic secretion, as well as other pathways in pan-cancer. CLCA2 appears to primarily activate pathways such as EMT (epithelial-mesenchymal transition), RAS/MAPK, RTK, apoptosis, TSC/mTOR, and PI3K/ AKT in pan-cancer. On the other hand, it seems to inhibit pathways like cell cycle, DNA damage, hormone AR, and hormone ER. Through single-cell functional analysis, it has been confirmed that CLCA2 is associated with diverse cellular functional states, encompassing DNA repair, EMT, hypoxia, invasion, metastasis, and quiescence. Furthermore, a substantial correlation has been observed between the expression of CLCA2 and drug sensitivity towards bosutinib, tipifarnib-P1, as well as other therapeutic agents. This research affirms that various cancer types express CLCA2 and its involvement in tumor advancement and immune penetration. CLCA2 possesses the capability to function as a noteworthy biomarker and target for therapeutic intervention in diverse cancer forms.

El canal de cloruro activado por calcio (CLCA2) desempeña una función vital en el proceso de tumorigénesis. Utilizando un sistema de análisis bioinformático, llevamos a cabo una investigación pan-cáncer en CLCA2 para explorar su asociación con el pronóstico tumoral y su participación en la inmunología. Para lograr este objetivo, examinamos la importancia pronóstica y el nivel de expresión de CLCA2 en múltiples tipos de cáncer utilizando las bases de datos TIMER y Sangerbox. El análisis de las redes de interacción de proteínas reveló proteínas vinculadas a CLCA2. Para investigar las posibles funciones biológicas y las vías de enriquecimiento de CLCA2 en el cáncer, se utilizaron las bases de datos SangerBox y GSCA. Además, durante el análisis se evaluó la expresión de CLCA2 en diferentes subtipos de cáncer. Luego se compararon varias condiciones funcionales de las células cancerosas con CLCA2 en la base de datos CancerSEA. Utilizando herramientas en línea como TISIDB y Assistant for Clinical Bioinformatics, la investigación exploró el vínculo entre CLCA2 y los subtipos inmunes. Además, evaluó la infiltración de células inmunitarias como parte del análisis y se empleó la aplicación de GDSA para investigar la importancia predictiva de CLCA2 en relación con la sensibilidad al fármaco. Los resultados de la investigación descubrieron patrones de expresión anormales de CLCA2 en diversas categorías de tumores, y su nivel de expresión demuestra una correlación con distintos subtipos de tumores. Se han observado fuertes asociaciones entre mayores tasas de supervivencia de los pacientes y CLCA2 en tipos de tumores específicos. Se observa una conexión notable entre diversos tipos de tumores, infiltración de células inmunitarias, subtipos inmunitarios y CLCA2. El análisis de enriquecimiento de KEGG indica que puede existir una conexión entre la expresión de CLCA2 y la secreción de renina, la secreción pancreática y otras vías en el pancáncer. CLCA2 parece activar principalmente vías como EMT (transición epitelial-mesenquimatosa), RAS/MAPK, RTK, apoptosis, TSC/mTOR y PI3K/AKT en pan-cáncer. Por otro lado, parece inhibir vías como el ciclo celular, el daño del ADN, la hormona AR y la hormona ER. Mediante análisis funcional unicelular, se ha confirmado que CLCA2 está asociado con diversos estados funcionales celulares, que abarcan la reparación del ADN, la EMT, la hipoxia, la invasión, la metástasis y la inactividad. Además, se ha observado una correlación sustancial entre la expresión de CLCA2 y la sensibilidad al fármaco hacia bosutinib, tipifarnib-P1, así como a otros agentes terapéuticos. Esta investigación indica que varios tipos de cáncer expresan CLCA2 y su participación en el avance tumoral y la penetración inmune. CLCA2 posee la capacidad de funcionar como un biomarcador notable y como un objetivo para la intervención terapéutica en diversas formas de cáncer.

Evaluación de la consistencia interna y dimensionalidad de la Escala de Capital Social Cognitivo en adultos colombianos

Introducción: durante las últimas dos décadas, el concepto de capital social se ha utilizado con creciente frecuencia en las ciencias de la salud debido a las relaciones directas e indirectas entre el capital social y la salud física y mental de las poblaciones. Por tanto, es necesario construir un instrumento para cuantificar este concepto con seguridad y confiabilidad. Objetivo: analizar la consistencia interna y dimensionalidad de una escala de siete ítems para medir el capital social en adultos de la población general de Colombia. Metodología: se realizó un estudio de validación en línea, que incluyó una muestra de 700 adultos de entre 18 y 76 años, el 68 % eran mujeres. Los participantes completaron una escala de siete ítems llamada Escala de Capital Social Cognitivo (ECSC). El alfa de Cronbach y el omega de McDonald se calcularon para probar la consistencia interna. Se realizaron análisis factoriales exploratorios y confirmatorios para explorar la dimensionalidad de la ECSC. Resultados: la ECSC presentó una consistencia interna baja (alfa de Cronbach de 0,56 y omega de McDonald de 0,59) y pobre dimensionalidad. Seguidamente, se probó una versión de cinco ítems (ECSC-5). La ECSC-5 mostró una alta consistencia interna (alfa de Cronbach de 0,79 y omega de McDonald de 0,80) y una estructura unidimensional con indicadores de bondad de ajuste aceptables. Discusión: la ECSC-5 presenta alta consistencia interna y una estructura unidimensional para medir el capital cognitivo social en adultos colombianos. Se recomienda la ECSC-5 para la medición del capital social en la población general colombiana. Futuras investigaciones deben corroborar estos hallazgos en aplicaciones de lápiz y papel y explorar otros indicadores de confiabilidad y validez.

Introduction: During the last two decades, the concept of social capital has been used increasingly frequently in health sciences due to the direct and indirect relationships between social capital and populations' physical and mental health. Therefore, it is necessary to build an instrument to quantify this concept confidently and reliably. Objective: The study aimed to internal consistency and dimensionality of a seven-item scale to measure social capital in Colombia's general population of adults. Methods: An online validation study included a sample of 700 adults aged between 18 and 76 years; 68% were females. Participants completed a seven-item scale called the Cognitive Social Capital Scale (CSCS). Cronbach's alpha and McDonald's omega were computed to test internal consistency. The authors explore the internal consistency and dimensionality of the CSCS. Results: The CSCS presented a low internal consistency (Cronbach's alpha of 0.56 and McDonald's omega of 0.59) and poor dimensionality. Then, the researchers tested a five-item version (CSCS-5). The CSCS-5 showed high internal consistency (Cronbach's alpha of 0.79 and McDonald's omega of 0.80) and a one-dimension structure with acceptable goodness-of-fit indicators. Discussion: The CSCS-5 presents high internal consistency and a one-dimensional structure to measure cognitive capital social in the Colombian sample. Authors can recommend measuring social capital in the general Colombian population. Further research should corroborate this pencil and paper application findings and explore other reliability and validity indicators.
