Introduction. Acute ischemic stroke is one of the leading global causes of morbidity and mortality. Mechanical thrombectomy has improved the functional prognosis of this condition; however, hemorrhagic transformation is a common complication. Spectral computed tomography (CT) imaging, as a neuroimaging control test, distinguishes contrast extravasation from hemorrhagic transformation due to the differential behavior of materials at dual energy levels. This distinction is valuable in its clinical therapeutic management.Material and methods. A single-center, observational, retrospective study was conducted in which the presence of various clinical, radiological, and therapeutic variables in patients with acute ischemic stroke treated with mechanical thrombectomy at our hospital between July 2022 and March 2023 was investigated using access to a dissociated database and medical records.Results. Out of 155 included patients, spectral cranial CT was performed in 63, and conventional cranial CT in 75. In the spectral CT group, 21 hyperdense images were detected, compared to 28 in the conventional CT group. In 42.8% of cases where hyperdensity was detected in the conventional CT group, it was not possible to distinguish between contrast extravasation and hemorrhagic transformation, in contrast to the 4.8% in the spectral CT group (p < 0.001).Conclusions. Spectral CT provides high diagnostic confidence to the radiologist in identifying the type of detected hyperdensity, thereby offering significant therapeutic confidence to the neurologist in early resuming anticoagulation therapy.

Health-Related Quality of Life in People with Advanced HIV Disease, from 1996 to 2021: Systematic Review and Meta-analysis.

The purpose of the study was to assess the effects of advanced HIV disease (AHD) on health-related quality of life (HRQoL) in PLHIV, the changes in HRQoL outcomes over the last 25 years, and the differences between countries according to level of economic development. We conducted a systematic review and meta-analysis. The search was conducted in PubMed and Web of Science using the terms: "health-related quality of life", "HQRoL", "HIV", "AIDS", "advanced HIV disease" and "low CD4 cells". Studies inclusion criteria were: adult population; initiated after 1996 and published before July 2021; clinical trials, cross-sectional, cohort, and case-control studies; studies analyzing the relationship between AHD and HRQoL; English or Spanish language. Standardized mean differences (d+) were calculated to estimate the effect size for the meta-analyses. Summary statistics were calculated using a random-effects model, and analyses of effect moderators, using mixed-effects models. The meta-analysis included 38 studies. The results indicated that HRQoL is worse in patients with AHD compared to those without. The main HRQoL domains affected were overall health perception and concern and physical and functional health and symptoms. We found a moderate impact for age and gender on some HRQoL domains. There were no differences in relation to socioeconomic inequities, country of residence, or time period analyzed. In conclusion, advanced HIV disease has a negative impact on health and well-being in PLHIV. Our results show that despite all the advances in antiretroviral treatments over the last 25 years, AHD persists as a source of extreme vulnerability, regardless of where PLHIV live.

RESUMEN: El objetivo del estudio fue evaluar los efectos de la enfermedad avanzada de sida (EAS) en la calidad de vida relacionada con la salud (CVRS) en personas que viven con el VIH (PVVIH), los cambios experimentados en la CVRS en los últimos 25 años y las diferencias entre países. Realizamos una revisión sistemática y metaanálisis. La búsqueda se llevó a cabo en PubMed y Web of Science utilizando los términos: "calidad de vida relacionada con la salud", "CVRS", "VIH", "SIDA", "enfermedad avanzada por VIH" y "células CD4 bajas". Los criterios de inclusión de los estudios fueron: población adulta; iniciado después de 1996 y publicado antes de julio de 2021; ensayos clínicos, estudios transversales, de cohorte y de casos y controles; estudios que analizan la relación entre EAS y CVRS; idioma inglés o español. Se calcularon diferencias de medias estandarizadas (d+) para estimar el tamaño del efecto para los metaanálisis. Los efectos promedios se calcularon utilizando un modelo de efectos aleatorios, y el análisis de moderadores utilizando modelos de efectos mixtos. El metaanálisis incluyó 38 estudios. Los resultados indicaron que la CVRS es peor en pacientes con EAS en comparación con aquellos sin EAS. Los principales dominios de CVRS afectados son la percepción de salud general y su preocupación, y la función física y de salud y los síntomas asociados. Encontramos un impacto moderado por edad y género en algunos dominios de CVRS. No encontramos diferencias en cuanto a las desigualdades socioeconómicas, país de residencia o período de tiempo analizado. En conclusión, la enfermedad avanzada por VIH tiene un impacto negativo en la salud y el bienestar en las personas con VIH. Nuestros resultados muestran que, a pesar de todos los avances en los tratamientos antirretrovirales en los últimos 25 años, el EAS persiste como una fuente de extrema vulnerabilidad, independientemente de dónde vivan las personas con VIH.

Quality indicators in the rational management of severe asthma: A Spanish multidisciplinary consensus.

AIM: Severe asthma is a complex, heterogeneous condition that can be difficult to control despite currently available treatments. Multidisciplinary severe asthma units (SAU) improve control in these patients and are cost-effective in our setting; however, their implementation and development can represent an organizational challenge. The aim of this study was to validate a set of quality care indicators in severe asthma for SAU in Spain. METHODS: The Carabela initiative, sponsored by SEPAR, SEAIC, SECA and SEDISA and implemented by leading specialists, analyzed the care processes followed in 6 pilot centers in Spain to describe the ideal care pathway for severe asthma. This analysis, together with clinical guidelines and SEPAR and SEAIC accreditation criteria for asthma units, were used to draw up a set of 11 quality of care indicators, which were validated by a panel of 60 experts (pulmonologists, allergologists, and health-policy decision-makers) using a modified Delphi method. RESULTS: All 11 indicators achieved a high level of consensus after just one Delphi round. CONCLUSIONS: Experts in severe asthma agree on a series of minimum requirements for the future optimization, standardization, and excellence of current SAUs in Spain. This proposal is well grounded on evidence and professional experience, but the validity of these consensus indicators must be evaluated in clinical practice.

Stereotactic Body Radiotherapy for Kidney Cancer: Ready for Prime Time?

The standard treatment for renal cell carcinoma (RCC) is surgery. However, a number of patients will not be candidates for surgical treatment or will reject this therapeutic approach. Therefore, alternative approaches are required. Historically, radiotherapy has been considered an ineffective treatment for RCC due to the radioresistance of renal tumour cells to conventional fractionation and the increased rate of toxicity. Stereotactic body radiotherapy (SBRT) is a radiotherapy technique that provides a non-invasive ablative treatment with remarkable rates of local control in both primary tumours and metastases in several locations, with a low associated morbidity due to the highly conformal dose and the use of image-guided techniques. Current evidence shows that a higher dose per fraction, achieving a higher biological effective dose, can overcome the radioresistance of RCC cells. Therefore, SBRT, as well as the combination of SBRT and new emerging immune therapies, has a potential role in the local treatment of primary RCC and oligometastatic RCC patients.

A differential therapeutic consideration for use of corticosteroids according to established COVID-19 clinical phenotypes in critically ill patients.

OBJECTIVE: To determine if the use of corticosteroids was associated with Intensive Care Unit (ICU) mortality among whole population and pre-specified clinical phenotypes. DESIGN: A secondary analysis derived from multicenter, observational study. SETTING: Critical Care Units. PATIENTS: Adult critically ill patients with confirmed COVID-19 disease admitted to 63 ICUs in Spain. INTERVENTIONS: Corticosteroids vs. no corticosteroids. MAIN VARIABLES OF INTEREST: Three phenotypes were derived by non-supervised clustering analysis from whole population and classified as (A: severe, B: critical and C: life-threatening). We performed a multivariate analysis after propensity optimal full matching (PS) for whole population and weighted Cox regression (HR) and Fine-Gray analysis (sHR) to assess the impact of corticosteroids on ICU mortality according to the whole population and distinctive patient clinical phenotypes. RESULTS: A total of 2017 patients were analyzed, 1171 (58%) with corticosteroids. After PS, corticosteroids were shown not to be associated with ICU mortality (OR: 1.0; 95% CI: 0.98-1.15). Corticosteroids were administered in 298/537 (55.5%) patients of "A" phenotype and their use was not associated with ICU mortality (HR=0.85 [0.55-1.33]). A total of 338/623 (54.2%) patients in "B" phenotype received corticosteroids. No effect of corticosteroids on ICU mortality was observed when HR was performed (0.72 [0.49-1.05]). Finally, 535/857 (62.4%) patients in "C" phenotype received corticosteroids. In this phenotype HR (0.75 [0.58-0.98]) and sHR (0.79 [0.63-0.98]) suggest a protective effect of corticosteroids on ICU mortality. CONCLUSION: Our finding warns against the widespread use of corticosteroids in all critically ill patients with COVID-19 at moderate dose. Only patients with the highest inflammatory levels could benefit from steroid treatment.

Objetivo: Evaluar si el uso de corticoesteroides (CC) se asocia con la mortalidad en la unidad de cuidados intensivos (UCI) en la población global y dentro de los fenotipos clínicos predeterminados. Diseño: Análisis secundario de estudio multicéntrico observacional. Ámbito: UCI. Pacientes: Pacientes adultos con COVID-19 confirmado ingresados en 63 UCI de España. Intervención: Corticoides vs. no corticoides. Variables de interés principales: A partir del análisis no supervisado de grupos, 3 fenotipos clínicos fueron derivados y clasificados como: A grave, B crítico y C potencialmente mortal. Se efectuó un análisis multivariado después de un propensity optimal full matching (PS) y una regresión ponderada de Cox (HR) y análisis de Fine-Gray (sHR) para evaluar el impacto del tratamiento con CC sobre la mortalidad en la población general y en cada fenotipo clínico. Resultados: Un total de 2.017 pacientes fueron analizados, 1.171 (58%) con CC. Después del PS, el uso de CC no se relacionó significativamente con la mortalidad en UCI (OR: 1,0; IC 95%: 0,98-1,15). Los CC fueron administrados en 298/537 (55,5%) pacientes del fenotipo A y no se observó asociación significativa con la mortalidad (HR = 0,85; 0,55-1,33). Un total de 338/623 (54,2%) pacientes del fenotipo B recibieron CC sin efecto significativo sobre la mortalidad (HR = 0,72; 0,49-1,05). Por último, 535/857 (62,4%) pacientes del fenotipo C recibieron CC. En este fenotipo, se evidenció un efecto protector de los CC sobre la mortalidad HR (0,75; 0,58-0,98). Conclusión: Nuestros hallazgos alertan sobre el uso indiscriminado de CC a dosis moderadas en todos los pacientes críticos con COVID-19. Solamente pacientes con elevado estado de inflamación podrían beneficiarse con el tratamiento con CC.

Transition of Adolescents With Severe Asthma From Pediatric to Adult Care in Spain: The STAR Consensus.

OBJECTIVES: To assess the degree of consensus among a multidisciplinary expert panel on the transition of adolescents with severe asthma from pediatric to adult care. METHODS: A 61-item survey was developed based on guidelines for other chronic diseases, covering transition planning, preparation, effective transfer, and follow-up. A 2-round Delphi process assessed the degree of consensus among 98 experts (49 pediatricians, 24 allergists, and 25 pulmonologists). Consensus was established with ≥70% agreement. RESULTS: Consensus was reached for 42 items (70%). Panelists were unable to agree on an age range for initiation of transition. The main goal during the transition identified by the experts is for adolescents to gain autonomy in managing severe asthma and prescribed treatments. The panelists agreed on the importance of developing an individualized plan, promoting patient autonomy, and identifying factors associated with the home environment. They agreed that the adult health care team should have expertise in severe asthma, biologics, and management of adolescent patients. Pediatric and adult health care teams should share clinical information, agree on the criteria for maintaining biological therapy, and have an on-site joint visit with the patient before the effective transfer. Adult health care professionals should closely follow the patient after the effective transfer to ensure correct inhaler technique, adherence, and attendance at health care appointments. CONCLUSION: This consensus document provides the first roadmap for Spanish pediatric and adult teams to ensure that key aspects of the transition process in severe asthma are covered. The implementation of these recommendations will improve the quality of care offered to the patient.

Objetivo: Evaluar el grado de consenso con un panel multidisciplinar de expertos sobre la transición del adolescente con asma grave de los servicios de pediatría a atención de adultos. Métodos: Se elaboró un cuestionario de 61 ítems basado en recomendaciones de transición para otras patologías crónicas, abarcando la planificación de la transición, preparación, transferencia efectiva y seguimiento. Se evaluó el nivel de consenso entre 98 expertos (49 pediatras, 24 alergólogos y 25 neumólogos) mediante un proceso Delphi de dos rondas. El consenso se estableció con un acuerdo ≥70%. Resultados: Cuarenta y dos ítems (70%) alcanzaron consenso. Los panelistas no alcanzaron consenso en el rango de edad para iniciar la transición. El principal objetivo a conseguir durante la transición según los expertos fue que el adolescente gane autonomía en el manejodel asma grave y tratamientos prescritos. Asimismo, alcanzaron acuerdo en la importancia de desarrollar un plan individualizado, promover la autonomía del paciente e identificar los factores clave en el entorno familiar. Los especialistas de adultos deben tener experiencia en asma grave y tratamientos biológicos, así como en el manejo de pacientes adolescentes. Los equipos sanitarios de pediatría y de adultos deben compartir la información clínica, consensuar los criterios para mantener la terapia biológica y realizar una visita conjunta con el paciente antes de la transferencia. Los especialistas de adultos deben realizar un seguimiento estrecho del paciente tras la transferencia para asegurar una correcta técnica inhalatoria, el cumplimiento del tratamiento y la asistencia a las citas sanitarias. Conclusiones: Este documento de consenso proporciona la primera hoja de ruta en España para que los equipos especialistas de pediatría y adultos garanticen aspectos clave del proceso de transición en pacientes adolescentes con asma grave.
