RESUMO

Chronic thromboembolic pulmonary hypertension (CTEPH) is a subtype of pulmonary hypertension characterized by the obstruction of pulmonary arteries secondary to chronic thromboembolism. Pulmonary thromboendarterectomy surgery (PTE) is the main treatment for patients with CTEPH, as it removes the chronic thrombi from the pulmonary arteries. Pulmonary reperfusion syndrome is a common complication of the surgery, which involves the development of pulmonary edema in the area where blood perfusion improves after the surgery. The incidence of this syndrome varies from 8 to 91% depending on the criteria used for diagnosis, and it is one of the most serious complications of pulmonary thromboendarterectomy. In such cases, circulatory support with extracorporeal membrane oxygenation (ECMO) has become a valuable therapeutic modality. We present the case of a 60-year-old woman with a history of acute pulmonary embolism due to deep vein thrombosis of the right pelvic limb who was diagnosed later with CTEPH who was admitted for scheduled surgical treatment involving bilateral PTE. However, during the immediate postoperative period, she developed cardiogenic shock and refractory hypoxemia secondary to pulmonary reperfusion syndrome following the surgical procedure. As a result, she required veno-venous ECMO circulatory support for 6 days, leading to resolution of the pulmonary condition and clinical improvement.

La hipertensión pulmonar tromboembólica crónica (HPTEC) es un subtipo de hipertensión pulmonar caracterizada por la obstrucción de las arterias pulmonares secundaria a tromboembolias crónicas. La cirugía de tromboendarterectomía pulmonar (TEAP) es el tratamiento principal para los pacientes con HPTEC, elimina los trombos crónicos de las arterias pulmonares. El síndrome de reperfusión pulmonar es una complicación común de la cirugía, se trata del desarrollo de edema pulmonar en el área en la que la perfusión sanguínea mejora después de la cirugía. La incidencia del síndrome varía del 8 al 91% según los criterios utilizados para diagnosticarlo y es una de las complicaciones más graves de la tromboendarterectomía pulmonar. En tales casos, el soporte circulatorio con oxigenación por membrana extracorpórea (ECMO) se ha convertido en una valiosa modalidad terapéutica. Presentamos el caso de una paciente de 60 años de edad con antecedente de tromboembolia pulmonar aguda secundaria a trombosis venosa profunda de miembro pélvico derecho a quien durante el seguimiento se realizó el diagnóstico de HPTEC e ingresó de manera programada para tratamiento quirúrgico con realización de TEAP bilateral, sin embargo durante el posquirúrgico inmediato presentó choque cardiogénico e hipoxemia refractaria secundarios a síndrome de reperfusión pulmonar, por lo cual requirió soporte circulatorio con ECMO venovenosa durante seis días, con resolución del cuadro pulmonar y mejoría clínica.

RESUMO

Introduction: This study analysed the psychometric properties of the Reward Probability Index (RPI) in an online Colombian sample with 1129 participants. Method: To conduct a cross-validation study, the sample was randomly divided into two subsamples. An exploratory factor analysis was conducted with the first subsample yielding a two-factor structure. Then, the fit of this two-factor model was tested on the second subsample by conducting a confirmatory factor analysis. Results: This model obtained a good fit to the data and measurement invariance across gender was observed. The RPI also showed good internal consistency according to both Cronbach's alpha and McDonald's omega, scoring .88 in both cases. The RPI demonstrated convergent construct validity given its correlations with other related measures such as the Environmental Reward Observation Scale (r = .81), and the full version of the Behavioral Activation Scale for Depression (r = .71). Conclusions: The RPI showed good psychometric properties in this Colombian sample.

Las variables se informaron con mediana (percentiles 25 y 75). Se analizaron con ANOVA de Kruskal-Wallis y ajuste respectivo, correlación de Spearman, el estadístico descriptivo de Bland-Altman y coeficiente de correlación intraclase (intervalo de confianza al 95%). Una p < 0.05 se consideró significativa. Resultados: Se estudiaron 244 muestras sanguíneas de 61 pacientes. Mujeres 30 (49%). Saturación de oxígeno y lactato fueron: arterial 98 (95.3, 99.4)% y 1.7 (1,1, 2.1); venosa periférica 85 (75.4, 94)% y 1.9 (1.35, 2.3); venosa central 68.8 (58.74, 70.2)% y 1.8 (1.3, 2.3); venosa central mezclada 66.8 (61.2, 73.1)% y 1.8 (1.3, 2.2), p < 0.05. El mejor coeficiente de correlación intraclase para la saturación de oxígeno fue de vena central a vena central mezclada: 0.856 (0.760, 0.914); del lactato: 0.954 (0.923, 0.972). Conclusiones: La saturación de oxígeno difiere en el circuito venoso-arterial a diferencia del lactato, donde son similares. Los mejores valores del coeficiente de correlación intraclase para el lactato y la saturación de oxígeno fueron los obtenidos en vena central y vena central mezclada.

Abstract Introduction: Oxygen saturation and lactate are markers of tissue hypoxia; they are obtained from central venous and mixed venous sample of the pulmonary artery. The simultaneous behavior of these parameters in the postoperative period of cardiac surgery is unknown. Objective: To characterize the lactate and oxygen saturation of the venous-arterial circuit of the postoperative patient from cardiac surgery. Methods: Design: Analytical cross-sectional. In consecutive patients after cardiac surgery, serum lactate and oxygen saturation of the venous-arterial circuit were obtained. The variables were reported with median (25.75 percentiles). They were analyzed with Kruskal-Wallis ANOVA and respective adjustment, Spearman correlation, the descriptive Bland-Altman statistic and intraclass correlation coefficient (95% confidence interval). A p < 0.05 was considered significant. Results: 244 blood samples from 61 patients were studied. Women 30 (49%). (Oxygen saturation) [lactate] were: arterial 98 (95.3, 99.4%) and 1.7 (1.1, 2.1); peripheral venous 85 (75.4, 94%) and [1.9 (1.35, 2.3)]; central venous 68.8 (58.74, 70.2%) and 1.8 (1.3, 2.3); mixed central venous 66.8 (61.2, 73.1%) and 1.8 (1.3, 2.2), p < 0.05. The best intraclass correlation coefficient for oxygen saturation were from central vein to mixed central vein 0.856 (0.760,0.914); and lactate: 0.954 (0.923, 0.972). Conclusions: The oxygen saturation differs in the venous-arterial circuit unlike lactate where they are similar. The best values of the intraclass correlation coefficient for lactate and oxygen saturation were those obtained in central vein and mixed central vein.

RESUMO

Telehealth strategies have become essential for responding to the sanitary emergency due to the COVID-19 pandemic. In this context, developing online psychological interventions (OPIs) that can treat and prevent psychological difficulties is gaining more relevance. This article describes an acceptance and commitment therapy (ACT) based OPI focused on repetitive negative thinking (RNT). This OPI is called Disentangled, Aware, and Committed (DAC) and represents an attempt to adapt previous RNT-focused ACT protocols to this format type. Study 1 evaluated content validity through the assessment of four experts in ACT regarding clarity, utility, pertinence, conceptual adjustment, and therapeutic goal fulfillment for each component of the DAC program. In Study 2, forty-one undergraduate clinical psychology trainees rated the components of the DAC program according to its clarity and perceived utility. These participants were enrolled in a randomized controlled trial that analyzed the efficacy of the DAC to prevent the usually observed increase in emotional symptoms and RNT among this population. Expert reviewers in Study 1 rated all DAC components as clear and useful for potential users, following a logical order, theoretically coherent with the ACT model, and successfully fulfilling its stated goals. In Study 2, the participants also rated the DAC components as clear and potentially useful for their lives. In conclusion, the DAC appears to be a feasible transdiagnostic OPI for treating and preventing emotional symptoms, which warrants further studies analyzing its efficacy.

RESUMO

The impact on mortality associated with covid-19 today exceeds five million deaths worldwide, and the number of deaths continues to rise. The complications of the survivors, socio-economic implications at a global level, economic limitations in the health systems, and physical and emotional exhaustion of health personnel are detrimental. Therapeutic strategies are required to limit the evolution of the disease, improve the prognosis of critically ill patients, and, in countries with low purchasing power, create affordable alternatives that can help contain the evolution towards the severity of infected people with mild to moderate symptoms. The misinformation and myths that today are more frequent on social networks and the implementation of practices without scientific support is a problem that aggravates the general panorama. This review aims to concentrate on the best evidence for treating SARS-CoV-2 infection in a simple and summarized manner, addressing therapies from their bases to the most innovative alternatives available today.

RESUMO

BACKGROUND: The Valuing Questionnaire (VQ) is considered as one of the most psychometrically robust instruments to measure valued living according to the acceptance and commitment therapy model. It consists of 10 items that are responded to on a 7-point Likert-type scale and has two factors: Progression and Obstruction. The Spanish version of the VQ showed good psychometric properties in Colombian samples. However, there is no evidence of the psychometric properties of the VQ in Spaniard samples. This study aims to analyze the validity of the VQ in a large Spaniard sample and analyze the measurement invariance with a similar Colombian sample. METHOD: The VQ was administered to a Spaniard sample of 846 adult participants from general online population. Cronbach's alpha and McDonald's omega were computed to analyze the internal consistency of the VQ. The fit of the VQ's two-factor model was tested through a confirmatory factor analysis with a robust maximum likelihood (MLR) estimation method. Afterward, we analyzed the measurement invariance across countries and gender. Convergent construct validity was analyzed with a package of questionnaires that evaluated experiential avoidance (Acceptance and Action Questionnaire-II, AAQ-II), emotional symptoms (Depression Anxiety and Stress Scale-21, DASS-21), life satisfaction (Satisfaction with Life Scale, SWLS), and cognitive fusion (Cognitive Fusion Questionnaire, CFQ). RESULTS: The internal consistency across samples was adequate (alphas and omegas were .85 for VQ-Progress and .84 for VQ-Obstruction). The two-factor model obtained a good fit to the data (RMSEA = 0.073, 90% CI [0.063, 0.083], CFI = 0.98, NNFI = 0.97, and SRMR = 0.053). The VQ showed strict invariance across countries and gender and showed theoretically coherent correlations with emotional symptoms, life satisfaction, experiential avoidance, and cognitive fusion. In conclusion, the Spanish version of the VQ demonstrated good psychometric properties in a large Spaniard sample.

RESUMO

OBJECTIVE: To examine the psychometric properties of the Spanish version of the Valuing Questionnaire (VQ) in Colombian clinical and nonclinical samples. METHOD: The VQ was administered to a total sample of 1820 participants, which included undergraduates (N = 762), general population (N = 724), and a clinical sample (N = 334). The questionnaire packages included measures of experiential avoidance, cognitive fusion, mindfulness, life satisfaction, and psychological difficulties. RESULTS: Across the different samples, internal consistency was good (global Cronbach's alpha of 0.83 for Progress and 0.82 for obstruction). Measurement invariance was found across samples and gender, and the two-factor model obtained a good fit to the data. The latent means of progress and obstruction of the clinical sample were lower and higher, respectively, than the latent means of the nonclinical samples. Correlations with other variables were in the expected direction. CONCLUSION: The Spanish version of the VQ showed good psychometric properties.

RESUMO

Delivering metaphors experientially has been emphasized in several psychotherapies, such as acceptance and commitment therapy. However, few research has analyzed the variables involved in the efficacy of metaphors. This experimental analog study aims to advance in this topic by analyzing the effect of two components involved in the experiential delivery of metaphors in psychotherapy. The first component is presenting the metaphor by asking the individual to imagine herself as the protagonist of the story versus presenting the metaphor in the third person (Self vs. Other). The second component is the inclusion of verbal cues prompting the relational elaboration of the rules derived from the metaphor content versus not including these prompts (Elaboration vs. No Elaboration). The effect of these components was tested in a double-blind, randomized, 2 × 2 factorial experiment that used the cold pressor task (CPT). Eighty-four participants were exposed to the CPT at the pretest. Afterward, participants were randomly assigned to four experimental protocols. The protocols were audiotaped and consisted of the same metaphor presented in four slightly different ways. Specifically, the protocol of Condition A involved a metaphor with Self and Elaboration, Condition B involved Self and No Elaboration, Condition C involved Other and Elaboration, and Condition D involved Other and No Elaboration. Then, participants were re-exposed to the CPT in the posttest. We hypothesized that Condition A (Self and Elaboration) would show a higher mean increase in pain tolerance than the remaining conditions, which would show similar results. The results were consistent with this hypothesis because Condition A showed a higher percentual increase in pain tolerance (Condition A: M = 268.21, SD = 167.47; Condition B: M = 180.86, SD = 73.01; Condition C: M = 204.81, SD = 100.19; Condition D: M = 175.41, SD = 76.00). A Bayesian informative hypothesis evaluation showed that this hypothesis obtained the highest posterior model probability. Thus, the results indicate that introducing metaphors by asking the individual to imagine herself as the protagonist of the story and providing prompts for relational elaboration might increase the therapeutic effect of the metaphor.
