Emotional Regulation as a Transdiagnostic Process of Emotional Disorders in Therapy: A Systematic Review and Meta-Analysis.

CONTEXT: Several studies have shown that emotional regulation (ER) is a transdiagnostic construct of emotional disorders. Therefore, if therapy improves ER, it would improve psychological distress. OBJECTIVE: This review assesses and compares the changes in ER due to psychological treatment in different therapies. METHODS: A systematic review and meta-analysis of RCTs published in the databases PubMed, PsycINFO and Web of Science was performed. It was registered in PROSPERO under the number CRD42023387317. Two independent experts in the field reviewed the articles. RESULTS: A total of 18 articles met the criteria for inclusion in the review. Analysis of these studies suggests that in unified protocol (UP), cognitive behaviour therapy, dialectical behaviour therapy (DBT) and mindfulness, there is evidence to support that a moderate effect occurs during treatment. Furthermore, in mindfulness and DBT, the effect was moderate in the follow-up period, while in UP, it was high. LIMITATIONS: Given the heterogeneity of the applied interventions and the methodological limitations found in the reviewed trials, the results should be interpreted with caution. CONCLUSIONS: UP, cognitive behaviour therapy, DBT and mindfulness can improve ER after therapy, while UP, DBT and mindfulness in the follow-up period. Other therapies, such as SKY or Flotation REST, require more research.

INTRODUCCIÓN: Varios estudios han demostrado que la regulación emocional es un constructo transdiagnóstico de los trastornos emocionales. Por lo tanto, si la terapia mejora la regulación emocional, también mejorará el malestar psicológico. OBJETIVO: Evaluar y comparar el cambio en la regulación emocional debido al tratamiento psicológico en diferentes terapias. MÉTODO: Se realizó una revisión sistemática y metaanálisis de ECA publicados en las bases de datos PubMed, PsycINFO y Web of Science. Se registró en PROSPERO con el número CRD42023387317. Dos expertos independientes en la materia revisaron los artículos. RESULTADOS: Un total de 18 artículos cumplieron los criterios de inclusión en la revisión. El análisis de estos estudios sugiere que en el Protocolo Unificado, la Terapia Cognitivo Conductual, la Terapia Dialéctica Conductual y terapias basadas en mindfulness existen evidencias que apoyan que se produce un efecto moderado durante el tratamiento. Además, en las terapias basadas en mindfulness y en la Terapia Dialéctica Conductual, el efecto se moduló en el periodo de seguimiento, mientras que en el Protocolo Unificado fue mayor. LIMITACIONES: Dada la heterogeneidad de las intervenciones aplicadas y las limitaciones metodológicas encontradas en los ensayos revisados, los resultados podrán interpretarse con cautela. CONCLUSIONES: UP, CBT, DBT y mindfulness pueden mejorar la ER tras la terapia, mientras que UP, DBT y mindfulness pueden mejorar la recuperación tras un tiempo de seguimiento. Otras terapias, como SKY o Flotation REST, requieren más investigación.

Can mindfulness-based interventions improve outcomes in cognitive-behavioural therapy for chronic insomnia disorder in the general population? Systematic review and meta-analysis.

Cognitive-behavioural therapy for insomnia (CBT-I) is the recommended first-line therapy for adults with chronic insomnia disorder (ID), which is characterized by hyperarousal. Mindfulness-based interventions (MBIs) are protocols aimed at stress reduction based on non-judgmental attention control in the present moment. However, MBIs have been increasingly used without a clear scientific basis. The objective of this analysis was to examine if MBIs could be useful as a component of the CBT-I therapeutic system through a systematic review and meta-analysis of randomized controlled trials (RCTs) and non-randomized studies (NRS) searched in PubMed, PsycINFO, Cochrane and WoS. The Insomnia Severity Index (ISI) was the primary outcome, while the Pittsburgh Sleep Quality Index (PSQI) and a composite sleep variable (CSV) were secondary outcomes. Thirteen articles corresponding to nine studies (three pragmatic RCTs, three explanatory RCTs and three NRS) were included. The omnibus test found that MBIs had a small to medium effect size on ISI nearing signification when comparing active control groups in the pretest-posttest period [Δ = 0.44, p = 0.07], a medium, non-significant, effect size on PSQI [Δ = 0.52, p = 0.18], and a significant though small effect size on CSV [Δ = 0.05, p < 0.01]. No heterogeneity was found. The analysis could not demonstrate that MBIs, combined with CBT-I components in some studies, positively affected ID in the general adult population. This was probably due to the lack of pragmatic designs and suitable measuring instruments. Recommendations are made for designing further studies to address these issues.

Mindfulness-based and mindfulness-informed interventions in bipolar disorder: A meta-analysis based on Becker's method.

Bipolar disorder is a highly disruptive and debilitating problem. Mindfulness-based and mindfulness-informed interventions have exponentially emerged as third-generation therapies, applied to a wide spectrum of disorders, including bipolar disorder. However, the reviews and meta-analyses published to date are limited in their conclusions, as they are based on single-group pretest-posttest cohort designs and mostly focused on mindfulness-based interventions. The present review and meta-analysis try to address these limitations, including studies on informed mindfulness, controlled and single-group designs. It used a specific meta-analytical procedure that allows an imputation procedure in those designs lacking a comparison group, by means of separate omnibus tests for the experimental and control group. A total of 13 studies (N = 331) were selected. The results showed an absence of effects on depression (g = 0.21) and mania (g = -0.13), but significant moderate effect on anxiety (g = 0.53). In conclusion, both mindfulness interventions showed robust evidence on anxiety symptoms in pretest-posttest periods compared to control groups. Few studies and lack of evidence of follow-up periods were the main limitations found.

Observations of two deep-sea chimaeroids in Icelandic waters.

Long-term survey time series repeated occurrence of the deep-sea chimaeroid species small-eyed rabbitfish Hydrolagus affinis and large-eyed rabbitfish H. mirabilis have been observed at same but few locations in Icelandic waters over 23 years. For H. affinis the catch at one specific station has consisted almost exclusively of mature males over the time period. Identification of potential aggregation locations is of vital importance to natural resource management because such aggregation may render these species vulnerable to potential fishing activities.

Spatial distribution of canine zoonotic enteroparasites in Bahía Blanca, Argentina.

The objectives of this research were: (1) to determine the occurrence of zoonotic enteroparasites in dog feces from Bahía Blanca, Argentina; (2) to characterize the spatial distribution of the parasites found in association with the quality of life index (QLI) in neighborhoods of Bahía Blanca; and (3) to determine if the presence of a particular parasite genus in a stool sample was facilitated or impeded by the presence of other parasite genera. Samples of dog stools (n=475) were collected between December 2012 and December 2013 in areas with varying QLI. The association between QLI values and the presence of parasites was analyzed using logistic regression. Overall enteroparasite occurrence was 36.6%. Parasitic forms found included nematode larvae, cysts of Blastocystis spp., Giardia spp., and oocysts of Cryptosporidium spp., and eggs of Ancylostoma caninum, Toxocara canis, cestodes and Trichuris spp. For certain enteroparasites, we detected significant associations between their occurrence and QLI. Feces collected in areas with medium and low QLI were 2.46 and 5.43 times more likely, respectively, to contain A. caninum than stools from the high-QLI area. Samples from areas with low QLI were 2.36 times more likely to contain Trichuris spp. than those from the high QLI area. Regarding protozoa, feces from areas with low QLI were 2.4 times more likely to be positive than those from areas with high QLI. We demonstrated that canine zoonotic parasites have a wide distribution in the study area, and that occurrence is higher in neighborhoods with lower QLI.

Factors influencing quality of processing in EMDR therapy.

This study presents a preliminary analysis of a new instrument oriented at the analysis of processes in EMDR trauma therapy, the Processing Difficulties Scale (PDS). This scale includes 17 items described by experienced EMDR consultants and practitioners as indicative of problems during memory reprocessing. The proposed factorial solution based on four factors explains a total variance explained of 55% and an adequate goodness of fit, based on the proposed indices: RMSEA = 0.07; TLI = 0.91; CFI = 0.95. Table 1 shows the factorial loads for each of the items. The first factor includes 5 items (7, 8, 9, 10, 11), the second factor includes 6 items (13, 14, 25, 27, 28, 31), the third factor includes 3 items (3, 16, 22) and the fourth factor includes 3 items (19, 23, 24). Confirmatory analysis confirms the factorial solution proposed in the exploratory analysis factor and based on four factors with 17 items. The analysis of internal consistency from Cronbach's alpha and the Omega index shows good internal consistency: Factor 1 (good processing; α = 0.92; ω = 0.94), Factor 2 (lack of generalization and/or absence of changes; α = 0.87; ω = 0.90), Factor 3 (poor emotional processing; α = 0.83; ω = 0.85) an Factor 4 (loss of dual attention; α = 0.82; ω = 0.83). In the case of the total scale, both coefficients exceeded 0.90, with an alpha of 0.92 and an Omega of 0.94. The convergent and discriminant validity criteria were estimated by calculating correlations, exploring the relationship between the factors resulting from the final result, the global severity index (GSI) of the SCL-90 and the level of improvement (NGS). These statistical analyses showed good levels of convergent and discriminant validity for all final factors. The PDS may offer a different perspective to analyze the controversy between clinicians and researchers about the need of a preparation phase in patients with complex early traumatization, dissociative symptoms and/or emotion dysregulation, and the different results in specific research around this topic. Exploring the problems in processing in a transdiagnostic way, in a preliminary analysis, we found that the number of early traumatic events measured with the ACE correlates positively with indicators of a loss of dual attention, while emotional dysregulation measured with the DERS does not predict poor processing. Finally, the dissociation measured with the DES seems to correlate positively with the indicators of a loss of dual attention during processing, not seeming to predict poor processing but did show a negative correlation with the indicators of good general processing. These results partially support the findings of some authors on the involvement of certain variables in the processing of traumatic memories, and it may be interesting to evaluate processing styles and their relationship with various indicators, to develop specific interventions in phase 2 of EMDR therapy, thus improving clinical interventions.

Comparison of two brief mindfulness interventions for anxiety, stress and burnout in mental health professionals: a randomised crossover trial.

Background: Anxiety, stress and burnout are a growing reality among mental health professionals, impacting negatively on them and their clients. Mindfulness-based interventions (MBIs) have demonstrated effectiveness in mitigating these sufferings. Nevertheless, there is a lack of knowledge on the impact of MBIs in Cuba. Objectives: To compare the effectiveness of two brief mindfulness-based interventions for reducing anxiety, work stress and burnout. Methods: A total of 104 mental health professionals from Havana (Cuba) participated in a randomised crossover trial. Group A received first an intervention involving body-centred practices (body scan and Hatha yoga) and a second intervention involving mind-centred practices (focused attention and open monitoring meditation). Group B received the same interventions but in reverse order. Four measures (anxiety, stress, burnout syndrome, and antecedents of burnout) were measured at baseline, posttest1, posttest2, and 6-months follow-up. Results: After the first intervention, there was a between-group difference for burnout syndrome, but the ES was similar for both groups. After the second intervention (implementing both practises), groups showed the largest effect sizes, and there was a between-group difference for antecedents of burnout. Results were partially maintained at 6-month follow-up. Conclusion: These results suggest that mind-centred practises can be as effective as body-centred practises for stress, anxiety and burnout reduction. The combination of both types of practises could be the most effective way of teaching mindfulness. About the sequence of implementation, teaching mind-centred practises first and then body-centred practises could be most effective for reducing antecedents of burnout.Clinical Trial Registration: www.clinicaltrials.gov NCT03296254.

Interactions between Personality and Types of Mindfulness Practice in Reducing Burnout in Mental Health Professionals.

Research on mindfulness-based interventions reports mainly on improvements at the group level. Thus, there is a need to elaborate on the individual differences in their effectiveness. The aim of this study was twofold: (1) to examine which personality factors could influence burnout reduction associated with different types of mindfulness practice and (2) to evaluate the interaction between personality factors and the amount of home practice; both aims were controlled for sociodemographic characteristics. A total of 104 Cuban mental health professionals, who participated in a crossover trial, were included. The effect of personality (Cattell's 16 Personality Factors) was analyzed through regression analysis. First, the results revealed that Emotional Stability and Vigilance could negatively moderate the effectiveness of mindfulness-based interventions. Second, participants who scored low in Sensitivity or Vigilance could benefit more from the body-centered practices (i.e., body scan and Hatha yoga practices), but no significant results for the mind-centered practices (i.e., classical meditation) were found. Third, participants who scored high in Self-reliance could benefit more from informal practice. Other personality factors did not appear to moderate the effect of the interventions, though previous experience in related techniques must be considered. Recommendations and clinical implications are discussed. Trial registration number is NCT03296254 (clinicaltrials.gov).

Mindfulness-Based Interventions for People with Schizophrenia: A Systematic Review and Meta-Analysis.

(1) Background: There is increasing interest in the practice of mindfulness-based interventions (MBIs) to treat people with schizophrenia, as evidenced by the publication of different randomized controlled trials (RCTs). However, no meta-analysis of RCTs has been carried out to date with the exclusive inclusion of this type of interventions. (2) Objective: To analyze empirical evidence regarding the effectiveness of MBIs for the improvement of clinical parameters associated with schizophrenia. Method: A systematic review and meta-analysis was conducted of RCTs published in the databases PsycINFO, PubMed, WOS, and Cochrane Library. (3) Results: A total of 10 articles (n = 1094) fulfilled the criteria for inclusion in the review. The analysis of these studies suggests that MBIs combined with standard interventions are able to generate significant improvements in a variety of clinical schizophrenia-related parameters, such as the intensity of overall symptomatology (g = 0.72), positive symptoms (g = 0.32), negative symptoms (g = 0.40), functioning level (g = 1.28), and awareness of illness (g = 0.65). (4) Conclusions: There is evidence that supports the effectiveness and safety of MBIs for the treatment of people with schizophrenia. The results obtained by MBIs are comparable to those obtained by cognitive-behavioral therapy for psychosis. However, given the heterogeneity of the applied interventions and the methodological limitations found in the reviewed trials, the results should be interpreted with caution.

Effectiveness of mindfulness-based interventions on anxiety for children and adolescents: A systematic review and meta-analysis.

AIM: This paper aims to investigate the extent to which mindfulness-based interventions serve to reduce anxiety in children and adolescents. A heterogeneous sample was used, including clinical and non-clinical population. METHODS: A literature search of controlled intervention studies published up to December 31, 2016, was carried out in PubMed, Lilacs, Cochrane, Embase, PsycInfo, Opengrey and Teseo databases. The effect size was calculated by Cohen's d. The Cochran Q statistic and the I2 index were used for the study of heterogeneity. An analysis was conducted using the random effects model. RESULTS: 829 articles were identified, of which 18 were finally selected. Of these, only three had statistically significant effect sizes. The overall combined result obtained was .013, but it did not result statistically significant (CI95% [-.102, .128].) The Q statistic was statistically significant (Q [18] = 28.497, P = . 39) and the I2 index was 40.34%, indicating a moderate heterogeneity. CONCLUSIONS: This meta-analysis did not obtain statistically significant results that could provide conclusions. In general, the studies analysed are small, of low power and have a marked heterogeneity, which implies that the findings are provisional and need to be supported by more robust studies. Although it cannot be ruled out that mindfulness-based interventions are not effective in the infant-juvenile population, it is also possible that this effect could not be detected due to the limited number of available studies. Larger investigations are needed, with sufficient statistical power and designs that control the variables potentially moderating, to establish clear conclusions.

Long-term success of complex recurrent rectovaginal fistula repair.

Rectovaginal fistulas (RVF) are the cause of major affliction to the affected patient and are a foremost challenge for the attending surgeon. Traditional techniques for treatment of RVF are quite extensive and particularly invasive. A more local procedure, with an acceptable success rate, would be the ideal first approach in treatment of this particular ailment. The aim of the current study is to show the step-by-step technique to correct a complex recurrent RVF (rRVF) using a biomesh implant. A 61-year-old female, who had undergone a prior vaginal hysterectomy, presented with a complex recurrent RVF. A third attempt to repair the RVF was conducted by a surgical team with the utilization of a biomesh, which resulted in no further recurrence of symptoms or RVF for up to 4 years. Complex rRVF repair by the placement of the biomesh allows for a secure and sustainable closure with potentially better prognosis for the patients.

Mindfulness trait and the potential mediating role of emotional regulation strategies in bipolar disorder / Mindfulness rasgo y el potencial papel mediador de las estrategias de regulación emocional en el trastorno bipolar

En este estudio transversal se investiga la asociación entre los principales síntomas del Trastorno bipolar (TB) y las dificultades asociadas a las estrategias de regulación emocional (ERE) adaptativas y desadaptativas. Además, este estudio examina los efectos mediadores de las ERE con el mindfulness rasgo y el TB. Método. Veinticuatro adultos con TB completaron la Escala de Conciencia de Atención Plena (MAAS), el Inventario de Depresión de Beck (BDI-II), la Escala de Autoevaluación de Manía de Altman (ARSM), el Inventario de Ansiedad Rasgo (STAI-R), y el Cuestionario de Regulación Emocional Cognitiva (CERQ). Resultados. El análisis de regresión múltiple mostró cómo la depresión se relacionaba significativa y positivamente con la autoculpabilización, mientras que la ansiedad rasgo estaba positivamente asociada con la autoculpabilización y el catastrofismo. En segundo lugar, el análisis de mediación mostró un efecto de mediación significativo para la autoculpabilidad en la relación entre mindfulness y depresión (a*b = -.15; ICB 95% [-.36, -.03]) y entre mindfulness y ansiedad rasgo (a*b = -.09; ICB 95% [-.27, -.01]). Conclusiones. Nuestros resultados informan del papel de la auto-culpabilidad y el catastrofismo en el TB y de cómo éstas podrían mediar significativamente entre el mindfulness rasgo y el TB. Estos resultados sugieren que una práctica de meditación enfocada en el catastrofismo y la autoculpabilidad puede ser especialmente útil para reducir los síntomas en los pacientes bipolares.(AU)

This cross-sectional study investigates the association between the main symptoms of Bipolar disorder (BD) and emotional regulation dif-ficulties in adaptive and maladaptive emotional regulation strategies (ERS). In addition, this study examines the possible mediating effects of ERS with dispositional mindfulnessand bipolar symptoms. Method.Twenty-four adults diagnosed with BD completed the Mindful Attention Awareness Scale (MAAS), the Beck Depression Inventory (BDI-II), the Altman Mania Self-Assessment Scale (ARSM), the Trait Anxiety Inventory (STAI-R), and the Cognitive Emotional Regulation Questionnaire (CERQ). Results. First, mul-tiple regression analysis showed how depression was significantly positively related to self-blame, whereas trait anxietywas positively associated with self-blame and catastrophizing. Second, the results of the mediation analy-sis have shown a significant mediation effect for the self-blamein the rela-tionship between mindfulnessand depression (a*b = -.15; BCI 95% [-.36, -.03]) and between mindfulnessand trait anxiety (a*b = -.09; BCI 95% [-.27, -.01]). Conclusions. Our results report the role of self-blame and catastrophiz-ing in BD and how these might significantly mediate between dispositional mindfulness and symptoms of depression and anxiety. These results suggest that a meditation practice focused on reducing catastrophizing and self-blame may be especially helpful for symptoms of depression and anxiety in bipolar patients.(AU)

Spatial modelling for low pathogenicity avian influenza virus at the interface of wild birds and backyard poultry.

Low pathogenicity avian influenza virus (LPAIV) is endemic in wild birds and poultry in Argentina, and active surveillance has been in place to prevent any eventual virus mutation into a highly pathogenic avian influenza virus (HPAIV), which is exotic in this country. Risk mapping can contribute effectively to disease surveillance and control systems, but it has proven a very challenging task in the absence of disease data. We used a combination of expert opinion elicitation, multicriteria decision analysis (MCDA) and ecological niche modelling (ENM) to identify the most suitable areas for the occurrence of LPAIV at the interface between backyard domestic poultry and wild birds in Argentina. This was achieved by calculating a spatially explicit risk index. As evidenced by the validation and sensitivity analyses, our model was successful in identifying high-risk areas for LPAIV occurrence. Also, we show that the risk for virus occurrence is significantly higher in areas closer to commercial poultry farms. Although the active surveillance systems have been successful in detecting LPAIV-positive backyard farms and wild birds in Argentina, our predictions suggest that surveillance efforts in those compartments could be improved by including high-risk areas identified by our model. Our research provides a tool to guide surveillance activities in the future, and presents a mixed methodological approach which could be implemented in areas where the disease is exotic or rare and a knowledge-driven modelling method is necessary.

Associations between fish and cold-water coral habitats on the Icelandic shelf.

The association between fish assemblages and cold-water coral habitats was evaluated based on analysis of longline catches in the Lónsdjúp trough, SE-Iceland. In 2009 and 2010, longlines were set in locations with varying coral cover within the trough. The study site is characterised by a depression (50-100 m deep), intersected by several ridges. Colonies of the cold-water coral Lophelia pertusa and other coral species were mainly found on the ridges. Among the fifteen fish species recorded, tusk (Brosme brosme) contributed ∼80% to the total fish abundance in both surveys and their catch per unit effort was twofold greater on the ridges than in adjacent flat areas. Multivariate analyses showed differences between the structure of fish communities on and off the ridges. Constrained redundancy ordinations followed by variance partitioning revealed that the structure of the fish community varied with seabed complexity, cold-water coral coverage and geographical position. It was not possible to separate between the effects of seabed complexity and coral cover, as these were strongly correlated.

Spatial distribution of canine zoonotic enteroparasites in Bahía Blanca, Argentina / Distribución espacial de enteroparásitos zoonóticos de caninos en Bahía Blanca, Argentina

The objectives of this research were: (1) to determine the occurrence of zoonotic enteroparasites in dog feces from Bahía Blanca, Argentina; (2) to characterize the spatial distribution of the parasites found in association with the quality of life index (QLI) in neighborhoods of Bahía Blanca; and (3) to determine if the presence of a particular parasite genus in a stool sample was facilitated or impeded by the presence of other parasite genera. Samples of dog stools (n = 475) were collected between December 2012 and December 2013 in areas with varying QLI. The association between QLI values and the presence of parasites was analyzed using logistic regression. Overall enteroparasite occurrence was 36.6%. Parasitic forms found included nematode larvae, cysts of Blastocystis spp., Giardia spp., and oocysts of Cryptosporidium spp., and eggs of Ancylostoma caninum, Toxocara canis, cestodes and Trichuris spp. For certain enteroparasites, we detected significant associations between their occurrence and QLI. Feces collected in areas with medium and low QLI were 2.46 and 5.43 times more likely, respectively, to contain A. caninum than stools from the high-QLI area. Samples from areas with low QLI were 2.36 times more likely to contain Trichuris spp. than those from the high QLI area. Regarding protozoa, feces from areas with low QLI were 2.4 times more likely to be positive than those from areas with high QLI. We demonstrated that canine zoonotic parasites have a wide distribution in the study area, and that occurrence is higher in neighborhoods with lower QLI.

Los objetivos del presente trabajo fueron los siguientes: a) determinar la ocurrencia de enteroparásitos zoonóticos en heces de perros de Bahía Blanca, Argentina; b) caracterizar la distribución espacial de los parásitos hallados en función del índice de calidad de vida (ICV) en barrios de Bahía Blanca, y c) determinar si la presencia de un género parasitario en particular en las heces fue facilitada o impedida por la presencia de otro/s. Se recolectaron muestras de heces de perro (n = 475) durante el período diciembre 2012-diciembre 2013 en áreas con diferente ICV. La asociación entre el ICV y la presencia de parásitos fue analizada mediante regresión logística. La ocurrencia global de enteroparásitos fue del 36,6%. Las formas parasitarias detectadas correspondieron a larvas de nematodos, a quistes de Blastocystis spp., Giardia spp. y Cryptosporidium spp., y a huevos de Ancylostoma caninum, Toxocara canis, cestodes y Trichuris spp. Se hallaron asociaciones significativas entre ocurrencia de algunos enteroparásitos e ICV. Las heces recolectadas en áreas con ICV medio y bajo mostraron una probabilidad de contener A. caninum 2,46 y 5,43 veces mayor, respectivamente, que las recolectadas en la zona de ICV alto. Las muestras de zonas con ICV bajo tuvieron una probabilidad 2,36 veces mayor de contener Trichuris spp. que aquellas de áreas con ICV alto. En lo referido a protozoos, las heces de áreas con ICV bajo tuvieron una probabilidad 2,4 veces mayor de presentar quistes que las heces de áreas con ICV alto. Se demostró que los parásitos zoonóticos caninos tienen una amplia distribución en el área estudiada y que la ocurrencia es más alta en los barrios con menor ICV.
