Background: In 2021, the Spanish Ministry of Health launched the CIBERPOSTCOVID project to establish what post COVID was. The present study reports the level of agreement among stakeholders on post COVID and its clinical and diagnostic characteristics in the Spanish health system. Methods: The agreement on post COVID among clinicians, public health managers, researchers and patients’ representatives was explored in a real-time, asynchronous online Delphi. In a two-wave consensus, respondents rated from 1 (total disagreement) to 6 (total agreement) 67 statements related to terminology, duration, etiology, symptoms, impact on quality of life, severity, elements to facilitate diagnosis, applicability in the pediatric population, and risk factors. Consensus was reached when 70 % of ratings for a statement were 5 or 6, with an interquartile range equal or less than 1. Findings: A total of 333 professionals and patients participated in this eDelphi study. There was agreement that post COVID was “a set of multi-organic symptoms that persist or fluctuate after acute COVID-19 infection and are not attributable to other causes” with a minimum duration of 3 months. The highest levels of agreement were found in the most frequent symptoms and its impacts on everyday activities. Aspects related to the diagnostic process and the measurement of its severity reached a lower level of consensus. There was agreement on the need to rule out previous health problems and assess severity using validated functional scales. However, no agreement was reached on the risk factors or specific features in the pediatric population. Interpretation: This policy-based consensus study has allowed the characterization of post COVID generating collective intelligence and has contributed to an operational definition applicable in clinical practice, health services management and useful for research purposes in Spain and abroad. Agreements are consistent with existing evidence and reference institutions at European and international level.

Abstract Aim To investigate the occurrence of traumatic stress symptoms (TSS) among healthcare workers active during the COVID-19 pandemic and to obtain insight as to which pandemic-related stressful experiences are associated with onset and persistence of traumatic stress. Methods This is a multicenter prospective cohort study. Spanish healthcare workers (N = 4,809) participated at an initial assessment (i.e., just after the first wave of the Spain COVID-19 pandemic) and at a 4-month follow-up assessment using web-based surveys. Logistic regression investigated associations of 19 pandemic-related stressful experiences across four domains (infection-related, work-related, health-related and financial) with TSS prevalence, incidence and persistence, including simulations of population attributable risk proportions (PARP). Results Thirty-day TSS prevalence at T1 was 22.1%. Four-month incidence and persistence were 11.6% and 54.2%, respectively. Auxiliary nurses had highest rates of TSS prevalence (35.1%) and incidence (16.1%). All 19 pandemic-related stressful experiences under study were associated with TSS prevalence or incidence, especially experiences from the domains of health-related (PARP range 88.4–95.6%) and work-related stressful experiences (PARP range 76.8–86.5%). Nine stressful experiences were also associated with TSS persistence, of which having patient(s) in care who died from COVID-19 had the strongest association. This association remained significant after adjusting for co-occurring depression and anxiety. Conclusions TSSs among Spanish healthcare workers active during the COVID-19 pandemic are common and associated with various pandemic-related stressful experiences. Future research should investigate if these stressful experiences represent truly traumatic experiences and carry risk for the development of post-traumatic stress disorder.

Antecedentes: La biopsia renal preimplante puede aportar información útil evolutiva postrasplante. Objetivo: Analizar el valor pronóstico de la biopsia renal de donantes de edad avanzada respecto al filtrado glomerular estimado MDRD-4 (FGe) al año del trasplante. Métodos: Estudiamos a 124 receptores de trasplante renal de donantes fallecidos de ≥60 años, con biopsia renal preimplante. Los trasplantes fueron realizados en nuestro centro, entre marzo del 2008 y mayo del 2012. Las biopsias se valoraron según el baremo propuesto por O’Valle et al. y se categorizaron en 3 grupos: 0-3, 4-5, 6-8 puntos. Se descartaron los riñones con una puntuación >8. El 77% de los donantes tenía ≥70 años. Resultados: El FGe medio (DE) del grupo 6-8 al año del trasplante: 38,5 (14,1) mL/min/1,73 m2 fue menor que el del grupo 4-5: 46,3 (15,7) (p = 0,03) y del grupo 0-3: 49,6 (12,5) (p = 0,04). Se registraron 7 (19%) pacientes con FGe

Background: Preimplantation renal biopsy provides potentially valuable information about post-transplant renal function. Objective: To assess the prognostic value of preimplantation kidney biopsy from older donors in determining 1-year post-transplant estimated glomerular filtration rate MDRD-4 (eGFR). Methods: We evaluated a cohort of 124 renal transplant recipients from deceased donors ≥60 years old, performed at our centre between March 2008 and May 2012. Biopsies were assessed by applying the score proposed by O’Valle et al. The overall score was stratified into 3 levels: 0–3, 4–5 and 6–8 points. Kidneys scoring >8 points were discarded. A total of 77% of the donors were ≥70 years. Results: One year post-transplant, mean eGFR (SD) was lower in transplant recipients with 6–8 points (38.5 [14.1] ml/min/1.73 m2) than in the group scoring 4–5 points (46.3 [15.7] [p = 0.03]) and the group scoring 0–3 (49.6 [12.5] [p = 0.04]). Seven patients (19%) had eGFR
