Anti-Xa activity below range is related to thrombosis in patients with severe COVID-19.

OBJECTIVE: We aimed to anlayse the relationship between anti-Xa activity below range and thomboembolic events. DESIGN: Single center prospective observational longitudinal cohort study (February-November 2021). SETTING: Patients admitted to the ICU of a University Hospital. PARTICIPANTS: Patients with severe COVID-19 pneumoniae. INTERVENTIONS: Enoxaparin was used for prophylactic and therapeutic anticoagulation. Enoxaparin dosing and dose adjustment were based on anti-Xa activity according to the hospital protocol. MAIN VARIABLES OF INTEREST: Target: thomboembolic events. PREDICTORS: demographics, pharmacotherapy, anti-Xa measurements, clinical data, and laboratory results. Logistic regression was used to identify independent risk factors for thomboembolic events. RESULTS: Data were available for 896 serum anti-Xa measurements from 228 subjects. Overall, 71.9% were male, with a median age of 62. Most patients needed invasive mechanical ventilation (87.7%) and mortality was 24.1%. A total of 28.9% new thomboembolic events were diagnosed. There were 27.1% anti-Xa measesurements below range. When multivariable logistic regression analysis was performed anti-Xa activity below range (RR, 4.2; p = 0.000), C-reactive protein (25 mg/L increase) (RR, 1.14; p = 0.005) and D-dimer (1000 ng/L increase) (RR, 1.06; p = 0.002) were the independent factors related to new thomboembolic events in patients with severe COVID-19. CONCLUSIONS: Anti-Xa activity below range, C-reactive protein and D-dimer were the independent factors related to thomboembolic events in patients with severe COVID-19. Purposely designed clinical trials should be carried out to confirm the benefit of an anti-Xa monitoring.

Bronchiectasis, lymphadenopathies related to BAFF overexpression and lymphoplasmacytic cystitis as adverse events associated with prolonged use of rituximab in systemic autoimmune rheumatic diseases.

BACKGROUND: The long-term use of rituximab (RTX) has been gaining ground in the treatment of systemic autoimmune diseases. The adverse events (AEs) associated with its use different to infections are being reported. METHODS: A cohort of patients with SAIDs treated at a high-complexity center in Cali (southwestern Colombia) with follow-up from January 2008 to December 2022 were examined to search for potential AEs associated with prolonged use of RTX. RESULTS: From 178 patients with long-term use of RTX 3 (1.68%) had lymphadenopathies with lymphoid follicular hyperplasia related to BAFF overexpression, 4 (2.24%) with bronchiectasis, and 4 (2.24%) with lymphoplasmacytic cystitis. CONCLUSION: Bronchiectasis, lymphoid follicular hyperplasia related to BAFF overexpression, and lymphoplasmacytic cystitis may be life-threatening long-term AEs in patients with prolonged use of RTX.

Invasive assessment of coronary microvascular dysfunction and cardiovascular outcomes across the full spectrum of CHD: a meta-analysis.

INTRODUCTION AND OBJECTIVES: Coronary microvascular dysfunction (CMD) is highly prevalent and is recognized as an important clinical entity in patients with coronary heart disease (CHD). Nevertheless, the association of CMD with adverse cardiovascular events in the spectrum of CHD has not been systemically quantified. METHODS: We searched electronic databases for studies on patients with CHD in whom coronary microvascular function was measured invasively, and clinical events were recorded. The primary endpoint was major adverse cardiac events (MACE), and the secondary endpoint was all-cause death. Estimates of effect were calculated using a random-effects model from published risk ratios. RESULTS: We included 27 studies with 11 404 patients. Patients with CMD assessed by invasive methods had a higher risk of MACE (RR, 2.18; 95%CI, 1.80-2.64; P<.01) and all-cause death (RR, 1.88; 95%CI, 1.55-2.27; P<.01) than those without CMD. There was no significant difference in the impact of CMD on MACE (interaction P value=.95) among different invasive measurement modalities. The magnitude of risk of CMD assessed by invasive measurements for MACE was greater in acute coronary syndrome patients (RR, 2.84, 95%CI, 2.26-3.57; P<.01) than in chronic coronary syndrome patients (RR, 1.77, 95%CI, 1.44-2.18; P<.01) (interaction P value<.01). CONCLUSIONS: CMD based on invasive measurements was associated with a high incidence of MACE and all-cause death in patients with CHD. The magnitude of risk for cardiovascular events in CMD as assessed by invasive measurements was similar among different methods but varied among CHD populations.

Technical complaints about collection bags represent the largest number of notifications in Brazil. The description of outcomes in the use of products for ostomy management is unclear and may lead to the underreporting of significant adverse events such as dermatitis. (AU)

Evaluation of tolerance to mercaptopurine in patients with inflammatory bowel disease and gastrointestinal intolerance to azathioprine / Evaluación de la tolerancia a la mercaptopurina en los pacientes con enfermedad inflamatoria intestinal e intolerancia gastrointestinal a la azatioprina

Background Thiopurines such as azathioprine (AZA) and mercaptopurine (MP) are commonly utilized to treat inflammatory bowel disease (IBD). Their use is frequently restricted due to gastrointestinal intolerance (GI). Previous retrospective studies have reported that AZA-intolerant patients may benefit from a switch to MP; yet the effectiveness of this strategy has not been prospectively evaluated.AimsTo assess GI tolerance to MP in patients who are intolerant to AZA, and to identify clinical predictors of GI intolerance to AZA or MP.MethodsA prospective, observational, single-cohort study was performed in 92 thiopurine-naïve IBD patients. They were started on a 50mg dose of AZA and escalated to 2.5mg/kg per day by week 2. Those with GI intolerance were rechallenged with a 50% dose of AZA, after which another dose escalation attempt was made. If symptoms persisted, they were switched to MP.ResultsThirty (32.6%) of the recruited patients suffered from GI intolerance to AZA. Of these, 15 did not present recurrence of symptoms after rechallenge with lower doses. Of 15 intolerant patients, 14 were switched to MP. Within the MP cohort, 8 patients (57%) were also intolerant to MP, 5 (36%) had no symptoms, and 1 (7%) was lost to follow-up. Female gender was the only independent predictor of GI intolerance to AZA.ConclusionsUp to half of the AZA-intolerant patients tolerated a 50% dose rechallenge that was successfully escalated. A switch to MP was tolerated in over a third of cases whom rechallenge failed. Our strategy (challenge–rechallenge–switch) achieved an overall GI tolerance to thiopurines in most of the patients.

Antecedentes Las tiopurinas como la azatioprina (AZA) y la mercaptopurina (MP) se utilizan comúnmente para tratar la enfermedad inflamatoria intestinal (EII). Su uso está frecuentemente restringido debido a la intolerancia gastrointestinal. Estudios retrospectivos anteriores han informado que los pacientes intolerantes a la AZA pueden beneficiarse de un cambio a MP; sin embargo, la eficacia de esta estrategia no ha sido evaluada prospectivamente.ObjetivosEvaluar la tolerancia gastrointestinal a MP en pacientes que son intolerantes a AZA e identificar predictores clínicos de intolerancia gastrointestinal a AZA o MP.MétodosSe realizó un estudio prospectivo, observacional y de cohorte única en 92 pacientes con EII que nunca habían recibido tiopurinas. Comenzaron con una dosis de 50mg de AZA y se aumentó a 2,5mg/kg por día en la semana 2. En aquellos con intolerancia gastrointestinal se administró una dosis del 50% de AZA que se fue incrementando en función de la tolerancia. Si los síntomas persistían, se cambiaba a MP.ResultadosTreinta (32,6%) de los pacientes reclutados presentaron intolerancia gastrointestinal a la AZA. De estos, 15 no presentaron recurrencia de los síntomas después de la nueva exposición. De los 15 pacientes que no toleraron una dosis más baja, 14 recibieron MP. De los que recibieron MP, 8 pacientes (57%) también eran intolerantes a MP, 5 (36%) no tenían síntomas y uno (7%) se perdió durante el seguimiento. El género femenino fue el único predictor independiente de intolerancia gastrointestinal a la AZA.ConclusionesHasta la mitad de los pacientes intolerantes a la AZA toleran una nueva exposición al 50% de la dosis. Se toleró un cambio a MP en más de un tercio de los casos en los que la reexposición fracasó. Nuestra estrategia logró la tolerancia gastrointestinal a tiopurinas en la mayoría de los pacientes.

Epidemiology of adverse events in Intensive Medicine units.

The severity of the critically ill patient, the practice of diagnostic procedures and invasive treatments, the high number of drugs administered, a high volume of data generated during the care of the critically ill patient along with a technical work environment, the stress and workload of work of professionals, are circumstances that favor the appearance of errors, turning Intensive Medicine Services into risk areas for adverse events to occur. Knowing their epidemiology is the first step to improve the safety of the care we provide to our patients, because it allows us to identify risk areas, analyze them and develop strategies to prevent the adverse events, or if this is not possible, be able to manage them. This article analyzes the main studies published to date on incidents related to safety in the field of critically ill patients.

Perfil de seguridad de nirmatrelvir-ritonavir: evidencia de eventos adversos por interacciones farmacológicas / Safety profile of nirmatrelvir-ritonavir: Evidence of adverse events due to drug-drug interactions

Objetivo: evaluar el perfil de seguridad de nirmatrelvir-ritonavir (NMV-r) en la práctica clínica real y analizar la relevancia clínica de las interacciones farmacológicas en el desarrollo de eventos adversos. Material y métodos: estudio observacional, retrospectivo en el que se evaluaron los datos de seguridad de pacientes tratados con NMV-r entre abril y julio de 2022. Se recopilaron datos demográficos y analíticos antes de comenzar el tratamiento. La duración del seguimiento fue de 28 días y se evaluó el número reacciones adversas reportadas, así como si fueron manejadas de forma ambulatoria o precisaron de asistencia sanitaria especializada y la presencia de deterioro de la función renal y hepática. Se revisó el tratamiento concomitante, identificando interacciones farmacológicas teóricas (IFT) cuya gravedad fue definida mediante la clasificación Lexi-interact. Resultados: el estudio incluyó 146 pacientes, 82 (56,16 %) eran mujeres, cuya mediana de edad fue de 65 años (22-95). El número de IFT detectadas y mantenidas durante el tratamiento con NMV-r fue de 164, siendo el porcentaje de pacientes con al menos una interacción de 62,33%. La mediana de IFT por paciente fue de uno (0-5). En 18 pacientes (11,84%) se reportó al menos un evento adverso (EA). Once EA se relacionaron potencialmente con alguna IFT, 7 pacientes requirieron contacto con asistencia hospitalaria para el manejo del EA, 8 pacientes presentaron deterioro de la función renal y 2 de la función hepática a los 28 días. Los principales grupos de fármacos implicados en la aparición de algún EA fueron los anticoagulantes orales, así como los calcio-antagonistas. Conclusiones: nuestros resultados muestran un elevado número de IFT detectadas entre NMV-r y otros fármacos, aunque la frecuencia de EA asociados fue baja. Este estudio proporciona un mayor conocimiento de los fármacos implicados en dichas interacciones y su potencial relación con la aparición de EA.(AU)

Objective: The aim of the study was to evaluate the safety profile of nirmatrelvir-ritonavir (NMV-r) in real clinical practice and to analyze the clinical relevance of drug-drug interactions in the development of adverse events. Methods: Observational, retrospective study in which safety data of patients treated with NMV-r between April and July 2022 in an outpatient setting were evaluated. The duration of follow-up was 28 days and the number of adverse reactions reported, as well as whether they were managed on an outpatient basis or required health care, and the presence of renal and hepatic function impairment were assessed. Concomitant treatment was reviewed, identifying theoretical drug-drug interactions (TDDIs) whose severity was defined using the Lexi-interact classification. Results: The study included 146 patients, 82 (56,16%) were women, whose median age was 65 years (22-95). The number of TDDIs detected and maintained during treatment with NMV-r was 164, with the percentage of patients with at least one interaction being 62,33%. The median number of TDDIs per patient was 1 (0-5). At least 1 adverse event (AE) was reported in 18 patients (11,84%). Eleven AEs were potentially related to any TDDI. Seven patients required contact with hospital assistance for AE management. Eight patients had impaired renal function and 2 had impaired liver function at 28 days. The main groups of drugs implicated in the occurrence of an AE were oral anticoagulants and calcium antagonists. Conclusions: Our results show a high number of TDDIs detected were detected between NMV-r and other drugs. This study provides greater knowledge of the drugs involved in such interactions and their potential relationship with the occurrence of adverse events.(AU)

Back to school after the pandemic: Adjustment of Spanish children and adolescents / La vuelta al colegio tras la pandemia: Adaptación de los niños y adolescentes españoles

Para frenar la propagación del COVID-19, el gobierno español aplicó medidas restrictivas, como el cierre escolar. Aunque los efectos de la pandemia en el bienestar emocional de los niños han sido estudiados, faltan estudios que examinen la adaptación escolar tras la pandemia y el papel que la infección ha tenido en el proceso de adaptación. El objetivo es analizar la relación entre los eventos estresantes relacionados con la escuela y la adaptación escolar después del confinamiento, incluyendo la ansiedad como mediadora. Los participantes fueron 219 padres de niños y adolescentes españoles de entre 3 y 18 años que completaron encuestas sobre la ansiedad de sus hijos (Spanish Brief Child Version of the Spence Children's Anxiety Scale), los eventos estresantes vividos relacionados con la escuela (Stressful Eventos relacionados con el Inventario de Pandemia), y la adaptación escolar (Escala de Ajuste de los Niños después del Cierre Escolar de la Pandemia). Los resultados mostraron mayor prevalencia en el evento estresante distancia social (87%). Tener COVID-19 y sufrir acoso escolar se relacionó directamente con una mayor ansiedad. Los niños que disminuyeron el contacto social y sufrieron acoso escolar mostraron peor adaptación escolar, siendo la ansiedad un mediador indirecto. Los hallazgos destacan la importancia de supervisar la adaptación escolar y promover estrategias para prevenir problemas emocionales en jóvenes expuestos a situaciones estresantes.(AU)

Aiming to mitigate the COVID-19 spread, the government of Spain applied restrictive measures, like schools’ closure. Although the ef-fects of the pandemic on children's emotional well-being have been stud-ied, there is a lack of studies examining school adjustment following the pandemic and the role that the infection has played in the adjustment pro-cess. The objective is to analyze the relationship between stressful events related to school experienced by children and their adjustment to school after the home confinement, including anxiety as a mediator variable. Par-ticipants were the parentsof 219 Spanish children and adolescents aged 3 and 18 years who completed a survey about their children’s anxiety (Span-ish Brief Child Version of the Spence Children’s Anxiety Scale), the stress-ful events experienced related to school (Stressful Events related to Pan-demic Inventory), and the adjustment to school (Adjustment of Children after Pandemic School Closure Scale). Results showed that social distance was the most reported stressful event (87%). Having COVID-19 and expe-riencing bullying were directly related to a high level of anxiety. Children ́s who decreased social contact and experienced bullying showed a worse ad-justment to school. Anxiety was an indirect mediator of this relationship. Findings highlight the importance of supervising school adaptation and promoting strategies to prevent emotional problems when the youths are exposed to stressful situations.(AU)

Current perspectives on the use of artificial intelligence in critical patient safety.

Intensive Care Units (ICUs) have undergone enhancements in patient safety, and artificial intelligence (AI) emerges as a disruptive technology offering novel opportunities. While the published evidence is limited and presents methodological issues, certain areas show promise, such as decision support systems, detection of adverse events, and prescription error identification. The application of AI in safety may pursue predictive or diagnostic objectives. Implementing AI-based systems necessitates procedures to ensure secure assistance, addressing challenges including trust in such systems, biases, data quality, scalability, and ethical and confidentiality considerations. The development and application of AI demand thorough testing, encompassing retrospective data assessments, real-time validation with prospective cohorts, and efficacy demonstration in clinical trials. Algorithmic transparency and explainability are essential, with active involvement of clinical professionals being crucial in the implementation process.

Taking a trauma and adversity perspective to climate change mental health.

The European Journal of Psychotraumatology has had a long interest in advancing the science around climate change and traumatic stress. In this special issue, we include papers that responded to a special call in this area. Six major themes emerge from these papers and together they contribute to trauma and adversity model of the mental health impacts of climate change. We argue that, in addition to individual vulnerability factors, we must consider the (i) cumulative trauma burden that is associated with exposure to ongoing climate change-related impacts; (ii) impact of both direct and indirect stressors; (iii) individual and community protective factors. These factors can then guide intervention models of recovery and ongoing resilience.

Trauma and adversity are central to understanding the mental health impacts of climate change.We present a trauma and adversity model of the mental health impacts of climate change.

Epidemiology of thromboembolic events in children and adolescents with antiphospholipid syndrome: A systematic review with meta-analysis.

BACKGROUND AND AIM: This was a systematic review and meta-analysis of the prevalence of thromboembolic events in children and adolescents with antiphospholipid syndrome (APS). METHODS: We searched PubMed, EMBASE and Web of Science to select relevant articles published between 1 January 2000 and 27 February 2022. We used the random-effects meta-analysis to estimate pooled point prevalence rates of thromboembolic events in studies with a minimum sample size of 30. RESULTS: We included five studies reporting data of 336 children and adolescents with primary APS and secondary APS (SAPS). Pooled point prevalence rates of initial general thrombosis, arterial thrombosis, venous thrombosis and stroke in individuals with seropositive APS were 98.2% (95% confidence interval [CI] 87.5-100), 27.6% (95% CI 21.4-34.2), 51.1% (95% CI 38.2-63.9) and 13.4% 95% CI (6.3-22.7), respectively. Pooled point prevalence rates of initial arterial and venous thromboses in children and adolescents with SAPS were 45.7% (95% CI 21.1-71.6) and 29.2% (95% CI 14.8-46), respectively. CONCLUSION: Arterio-venous thromboembolism is highly frequent in children and adolescents with SAPS. More studies using thrombotic and non-thrombotic APS classification criteria are warranted to better assess the frequency and predictors of thromboembolism in age- and ancestry-diverse pediatric populations affected by different types of APS.

Antecedentes y objetivo: Se trata de una revisión sistemática y un metaanálisis de la prevalencia de acontecimientos tromboembólicos en niños y adolescentes con síndrome antifosfolípido (SAF). Métodos: Se realizaron búsquedas en PubMed, EMBASE y Web of Science para seleccionar los artículos pertinentes publicados entre el 1 de enero de 2000 y el 27 de febrero de 2022. Se utilizó el metaanálisis de efectos aleatorios para estimar las tasas de prevalencia puntual agrupadas de eventos tromboembólicos en estudios con un tamaño muestral mínimo de 30. Resultados: Se incluyeron cinco estudios con datos de 336 niños y adolescentes con APS primario y APS secundario (SAPS). Las tasas de prevalencia puntual agrupadas de trombosis general inicial, trombosis arterial, trombosis venosa e ictus en individuos con SAF seropositivo fueron de 98,2% (intervalo de confianza [IC] 95%: 87,5-100), 27,6% (IC 95%: 21,4-34,2), 51,1% (IC 95%: 38,2-63,9) y 13,4% (IC 95%: 6,3-22,7), respectivamente. Las tasas de prevalencia puntual agrupadas de trombosis arteriales y venosas iniciales en niños y adolescentes con SAF secundario fueron de 45,7% (IC 95%: 21,1-71,6) y de 29,2% (IC 95%: 14,8-46), respectivamente. Conclusión: La tromboembolia arteriovenosa es muy frecuente en niños y adolescentes con SAF. Se justifica la realización de más estudios que utilicen criterios de clasificación del SCA trombótico y no trombótico para evaluar mejor la frecuencia y los factores predictivos de la tromboembolia en poblaciones pediátricas de edad y ascendencia diversas afectadas por distintos tipos de SCA.(AU)

Introducción: El conocimiento de los eventos adversos (EA) en los hospitales de agudos es un aspecto de especial relevancia en la seguridad del paciente. Su incidencia oscila entre un 3-17% y la cirugía se relaciona con la aparición de entre un 46-65% de todos los EA. Material y métodos: Se realiza un estudio observacional, descriptivo, retrospectivo y multicéntrico, con la participación de 31 hospitales de agudos españoles, para la determinación y análisis de los EA en los servicios de cirugía general. Resultados: La prevalencia de EA fue del 31,53%. Los tipos de EA más frecuentes fueron de tipo infeccioso (35%). Los pacientes con mayores grados de ASA, mayor complejidad y un tipo de ingreso urgente son factores asociados a la presencia de EA. A la mayoría de los pacientes se les atribuyó una categoría de daño F (daño temporal al paciente que requiera iniciar o prolongar la hospitalización) (58,42%). El 14,69% de los EA son considerados graves. El 34,22% de los EA se consideraron evitables. Conclusiones: La prevalencia de EA en los pacientes de cirugía general y del aparato digestivo (CGAD) es elevada. La mayor parte de los EA fueron de tipo infeccioso. El EA más frecuente fue la infección de herida o sitio quirúrgico. Los pacientes con mayores grados de ASA, mayor complejidad y un tipo de ingreso urgente son factores asociados a la presencia de EA. La mayoría de los EA detectados han supuesto un daño leve o moderado sobre los pacientes. Alrededor de un tercio de EA fueron evitables.(AU)

Introduction: Knowledge of adverse events (AE) in acute care hospitals is a particularly relevant aspect of patient safety. Its incidence ranges from 3% to 17%, and surgery is related to the occurrence of 46%-65% of all AE. Material and methods: An observational, descriptive, retrospective, multicenter study was conducted with the participation of 31 Spanish acute-care hospitals to determine and analyze AE in general surgery services. Results: The prevalence of AE was 31.53%. The most frequent types of AE were infectious (35%). Higher ASA grades, greater complexity and urgent-type admission are factors associated with the presence of AE. The majority of patients (58.42%) were attributed a category F event (temporary harm to the patient requiring initial or prolonged hospitalization); 14.69% of AE were considered severe, while 34.22% of AE were considered preventable. Conclusions: The prevalence of AE in General and GI Surgery (GGIS) patients is high. Most AE were infectious, and the most frequent AE was surgical site infection. Higher ASA grades, greater complexity and urgent-type admission are factors associated with the presence of AE. Most detected AE resulted in mild or moderate harm to the patients. About one-third of AE were preventable.(AU)

Value of the tumor inhibitor of cellular immunity PDL-1 in the incidence of venous thrombosis in patients with gastric cancer.

INTRODUCTION: Gastric cancer is one of the cancers most associated with thromboembolic phenomena. The objective of this article is to study if there is a correlation between thromboembolic phenomena in gastric cancer and tumor expression of PDL-1. METHODS: To this end, the association between thromboembolic events and PDL-1 expression was retrospectively studied in a sample of 46 patients from our hospital. RESULTS: The results obtained revealed a statistically significant difference between the percentage of thromboembolic events between positive and negative PDL-1 with an increase in the latter with a P value of 0.034. CONCLUSION: In conclusion, the expression of PDL-1, and with it, of an inhibitory factor of the cellular immune response, correlates with a decrease in thromboembolic events in patients with gastric cancer, which could indicate the crucial role of the immune response in which thromboembolic events occur.

Gammagrafía de perfusión miocárdica en la evaluación del riesgo cardiovascular en el trasplante hepático de adultos / Myocardial perfusion scintigraphy in the assessment of cardiovascular risk in adult liver transplantation

Introducción El estudio diagnóstico no invasivo del riesgo cardiovascular en pacientes que van a ser llevados a trasplante hepático no es claro especialmente en asintomáticos. Respecto a la gammagrafía de perfusión miocárdica (GPM) se ha pensado que la reserva vasodilatadora deteriorada en estos pacientes puede reducir su rendimiento. El objetivo es valorar el papel de la GPM en la evaluación prequirúrgica de los pacientes que van a ser tratados mediante un trasplante hepático. Material y métodos Estudio retrospectivo, descriptivo y observacional. Se incluyó a todos los pacientes adultos llevados a trasplante hepático entre 2017 y 2021 que tuvieran GPM previa. Se describen los hallazgos de la GPM y se correlacionaron con los hallazgos de angiografía invasiva y con la aparición o no de eventos cardiovasculares peri y postrasplante. Resultados De 188 pacientes trasplantados (edad promedio: 57 años, DE: 12), 178 tenían perfusión miocárdica previa, 82 (46%) pacientes no tenían factores de riesgo cardiovascular y 5 (2,8%) tenían antecedente de enfermedad coronaria. De las GPM, 177 fueron con estrés con dipiridamol realizadas en promedio 10 meses antes del trasplante. Únicamente 17/178 (9,5%) estudios fueron anormales. El seguimiento medio fue de 38 meses (DE: 10). De los pacientes con GPM normal, solo 2 (1,2%) presentaron eventos cardiovasculares, ambos con estudios realizados más de 2años atrás. No hubo muertes de origen cardiovascular. Conclusiones La GPM es una técnica segura y confiable en la valoración cardiovascular en pacientes candidatos a trasplante hepático dada la baja tasa de falsos negativos en el seguimiento (AU)

Introduction The non-invasive diagnostic study of cardiovascular risk in patients who are going to undergo liver transplantation is not clear, especially in asymptomatic patients. Regarding myocardial perfusion scintigraphy (MPS), it has been thought that the impaired vasodilator reserve in these patients may reduce its performance. The objective is to assess the role of the MPS in the pre-surgical evaluation of patients who are going to undergo liver transplantation. Material and methods Retrospective, descriptive and observational study was designed. All adult patients undergoing liver transplantation between 2017 and 2021 who had previous MPS were included. The findings of MPS were described and correlated with the findings of invasive angiography and with the appearance or not of peri- and post-transplant cardiovascular events. Results There were a total of 188 transplanted patients (mean age: 57 years, SD: 12), 178 had previous myocardial perfusion, 82 (46%) patients had no cardiovascular risk factors, and 5 (2.8%) had a history of coronary disease. Of the MPS, 177 were with dipyridamole stress performed on average 10 months before transplantation. Only 17/178 (9.5%) studies were abnormal. The mean follow-up was 38 months (SD: 10). Of the patients with normal MPS, only 2 (1.2%) presented cardiovascular events, both with studies performed more than 2years before the procedure. There were no deaths of cardiovascular origin. Conclusions MPS is a safe and reliable technique for cardiovascular assessment of patients who are candidates for liver transplantation, given the low rate of false negatives during follow-up (AU)

Mental health impacts of climate change and extreme weather events on mothers.

Background: The perinatal period is a time of increased vulnerability for perinatal mood and anxiety disorders (PMADs). Emotional trauma is a risk factor for PMAD development and is common among survivors of extreme weather events (EWEs), which are becoming more frequent and intense as the climate crisis progresses. EWE-related stress and anxiety have not been extensively studied in the perinatal population. However, the limited available data suggest a negative impact of EWE exposure on perinatal mental health, warranting further investigation and investment.Objective: To address this knowledge gap, we interviewed new Australian mothers to understand how EWEs affect the mental health of the perinatal population.Method: Australian mothers (18 years of age or older) with a baby under 12 months of age were recruited to participate in a single virtual focus group session (seven group sessions were run in total) and complete an anonymous survey. Participants were asked questions regarding their concerns about extreme weather and its impact, as well as their general maternal functioning. Maternal functioning, depression, and climate distress were measured via the survey.Results: The study sample comprised 31 Australian mothers (Mage = 31.74, SD = 4.86), predominantly located in Queensland. Findings from the focus groups suggested six key themes; however, of focus to this study are three themes related to maternal mental health: health and well-being, helplessness and avoidant coping, and resilience and adaptation. Predominant subthemes focused on trauma resulting from EWE exposure, economic and heat concerns, social isolation, hopelessness about the future, and feelings of resilience.Conclusions: The evidence linking adverse perinatal mental health outcomes with climate change and EWEs highlights the urgent need for interventions in this context to protect perinatal mental health and well-being. By acknowledging the traumatic impact of these experiences on mothers, this study supports advocacy for policies that specifically address this issue.

The extra consideration of navigating climatic events with children represented a complicating factor in addition to the demands of motherhood.Heat presented as a serious concern for participants, often as part of maintaining the balance between protecting their children's health and well-being and preserving their own mental health.Mothers simultaneously were disengaged from climate-related discussion or action and expressed feelings of helplessness in the face of the magnitude of climate change.

Implementation of esophageal endoscopic submucosal dissection in Spain: Results from the nationwide registry. / Implementación de la disección endoscópica submucosa esofágica en España: resultados del registro nacional.

INTRODUCTION AND AIMS: The outcomes of endoscopic submucosal dissection (ESD) in the esophagus have not been assessed in our country. Our primary aim was to analyze the effectiveness and safety of the technique. MATERIAL AND METHODS: Analysis of the prospectively maintained national registry of ESD. We included all superficial esophageal lesions removed by ESD in 17 hospitals (20 endoscopists) between January 2016 and December 2021. Subepithelial lesions were excluded. The primary outcome was curative resection. We conducted a survival analysis and used logistic regression analysis to assess predictors of non-curative resection. RESULTS: A total of 102 ESD were performed on 96 patients. The technical success rate was 100% and the percentage of en-bloc resection was 98%. The percentage of R0 and curative resection was 77.5% (n=79; 95%CI: 68%-84%) and 63.7% (n=65; 95%CI: 54%-72%), respectively. The most frequent histology was Barrett-related neoplasia (n=55 [53.9%]). The main reason for non-curative resection was deep submucosal invasion (n=25). The centers with a lower volume of ESD obtained worse results in terms of curative resection. The rate of perforation, delayed bleeding and post-procedural stenosis were 5%, 5% and 15.7%, respectively. No patient died or required surgery due to an adverse effect. After a median follow-up of 14months, 20patients (20.8%) underwent surgery and/or chemoradiotherapy, and 9 patients died (mortality 9.4%). CONCLUSIONS: In Spain, esophageal ESD is curative in approximately two out of three patients, with an acceptable risk of adverse events.
