Escala MPN-SAF TSS o MPN-10 de calidad de vida en Policitemia Vera

Poster [PC-240] Introducción: Los síntomas clínicos en las neoplasias mieloproliferativas crónicas suponen un gran impacto en la calidad de vida de estos pacientes. Desde 2.013 la escala MPN-SAF TSS (“The Myeloproliferative Neoplasm Symptom Assessment Form Total Symptom Score”), compuesta por 10 ítems (astenia, saciedad temprana, malestar abdominal, inactividad, problemas al concentrarse, sudoración nocturna, prurito, dolor óseo, fiebre y pérdida de peso), permite una evaluación cuantificable y comparativa de los síntomas. Métodos: Estudio descriptivo y prospectivo de pacientes en seguimiento ambulatorio en el Servicio de Hematología (HUMS) diagnosticados de Policitemia Vera según criterios OMS 2016. Periodo de estudio: Enero 2018-Mayo 2018. Variables analizadas: demográficas, clínicas, hematimétricas y puntuación global e individual por ítems de escala MPNSAF TSS. Puntuación por ítem entre 0 (ausente) y 10 (lo peor posible). Puntuación total posible: 100 puntos. Paciente: alto riesgo: =60 años y episodio trombótico. Paciente: bajo riesgo: <60 años sin episodio previo trombótico. Resultados: Se han estudiado un total de 48 pacientes cuya media de edad fue de 71, 3 años (rango 46-94). La situación hematimétrica de los pacientes en el momento de la encuesta fue la siguiente: la media de Hemoglobina (Hb) y Hematocrito (Hto): 15, 10 g/dL y 46, 47% respectivamente (1 presentaba anemia (Hb =12 g/dL y Hto =38%) y 17 eritrocitosis (Hb =16 g/dL y Hto =48%). Media de leucocitosis: 8, 25.10³/µL (solo 1 presentaba neutropenia) y media de plaquetas: 287. 10³/µL (3 presentaban trombopenia (=130. 10³/µL y 6 trombocitosis (=400. 10³/µL). Del total de pacientes un 43% presentaban esplenomegalia. 34 pacientes pertenecían al grupo de alto riesgo (32 con tratamiento citorreductor) y 14 al de bajo riesgo (8 con flebotomías), todos ellos con tratamiento antiagregante asociado. La mediana global de la escala MPN-SAF TSS fue 17 (rango 2-58). Dentro del grupo de alto riesgo 26 pacientes (76, 47%) se encontraban dentro del primer cuartil (0-25 puntos), 4 pacientes (11, 76%) dentro del segundo cuartil (25-50 puntos), 4 (11, 76%) dentro del tercer cuartil (50-75 puntos) y ninguno superaba los 75 puntos. Dentro del grupo de bajo riesgo, 10 pacientes (71, 42%) dentro del primer cuartil y 4 (28, 57%) dentro del segundo. La puntuación media de cada uno de los síntomas y el porcentaje de pacientes que superaba los 5 puntos en cada ítem fue: “fatiga” 3, 96 (56, 25%), “dolor óseo” 3, 19 (29, 17%), “saciedad precoz” 2, 35 (33, 33%), “problemas de concentración” 2, 35 (27, 08%), “sudoración nocturna” 2, 40 (27, 08%), “malestar abdominal” 1, 50 (18, 75%), “prurito” 1, 65 (12, 05%), “pérdida de peso” 0, 50 (6, 25%) y “fiebre” 0, 10 (0%). La fatiga fue el síntoma más prevalente, tanto en pacientes de alto y bajo riesgo. Conclusiones: La escala MPN-SAF TSS permite una evaluación concisa, válida y precisa de la carga de síntomas, demostrando que gran parte de estos pacientes presentan una calidad de vida mejorable a pesar de presentar estabilidad hematimétrica. Esta herramienta permite detectar sintomatología no previsible analíticamente y dirigir la entrevista clínica y, así, poder llevar a cabo un plan de tratamiento personalizado y dirigido de los síntomas

Search for dark matter produced in association with a hadronically decaying vector boson in pp collisions at sqrt (s) = 13 TeV with the ATLAS detector

A search is presented for dark matter produced in association with a hadronically decaying W or Z boson using 3.2 fb−1 of pp collisions at View the MathML sources=13 TeV recorded by the ATLAS detector at the Large Hadron Collider. Events with a hadronic jet compatible with a W or Z boson and with large missing transverse momentum are analysed. The data are consistent with the Standard Model predictions and are interpreted in terms of both an effective field theory and a simplified model containing dark matter

Elective cancer surgery in COVID-19-free surgical pathways during the SARS-CoV-2 pandemic: An international, multicenter, comparative cohort study

PURPOSE As cancer surgery restarts after the first COVID-19 wave, health care providers urgently require data to determine where elective surgery is best performed. This study aimed to determine whether COVID-19–free surgical pathways were associated with lower postoperative pulmonary complication rates compared with hospitals with no defined pathway. PATIENTS AND METHODS This international, multicenter cohort study included patients who underwent elective surgery for 10 solid cancer types without preoperative suspicion of SARS-CoV-2. Participating hospitals included patients from local emergence of SARS-CoV-2 until April 19, 2020. At the time of surgery, hospitals were defined as having a COVID-19–free surgical pathway (complete segregation of the operating theater, critical care, and inpatient ward areas) or no defined pathway (incomplete or no segregation, areas shared with patients with COVID-19). The primary outcome was 30-day postoperative pulmonary complications (pneumonia, acute respiratory distress syndrome, unexpected ventilation). RESULTS Of 9,171 patients from 447 hospitals in 55 countries, 2,481 were operated on in COVID-19–free surgical pathways. Patients who underwent surgery within COVID-19–free surgical pathways were younger with fewer comorbidities than those in hospitals with no defined pathway but with similar proportions of major surgery. After adjustment, pulmonary complication rates were lower with COVID-19–free surgical pathways (2.2% v 4.9%; adjusted odds ratio [aOR], 0.62; 95% CI, 0.44 to 0.86). This was consistent in sensitivity analyses for low-risk patients (American Society of Anesthesiologists grade 1/2), propensity score–matched models, and patients with negative SARS-CoV-2 preoperative tests. The postoperative SARS-CoV-2 infection rate was also lower in COVID-19–free surgical pathways (2.1% v 3.6%; aOR, 0.53; 95% CI, 0.36 to 0.76). CONCLUSION Within available resources, dedicated COVID-19–free surgical pathways should be established to provide safe elective cancer surgery during current and before future SARS-CoV-2 outbreaks

Elective Cancer Surgery in COVID-19-Free Surgical Pathways During the SARS-CoV-2 Pandemic: An International, Multicenter, Comparative Cohort Study.

Effects of hospital facilities on patient outcomes after cancer surgery: an international, prospective, observational study

Background Early death after cancer surgery is higher in low-income and middle-income countries (LMICs) compared with in high-income countries, yet the impact of facility characteristics on early postoperative outcomes is unknown. The aim of this study was to examine the association between hospital infrastructure, resource availability, and processes on early outcomes after cancer surgery worldwide.Methods A multimethods analysis was performed as part of the GlobalSurg 3 study-a multicentre, international, prospective cohort study of patients who had surgery for breast, colorectal, or gastric cancer. The primary outcomes were 30-day mortality and 30-day major complication rates. Potentially beneficial hospital facilities were identified by variable selection to select those associated with 30-day mortality. Adjusted outcomes were determined using generalised estimating equations to account for patient characteristics and country-income group, with population stratification by hospital.Findings Between April 1, 2018, and April 23, 2019, facility-level data were collected for 9685 patients across 238 hospitals in 66 countries (91 hospitals in 20 high-income countries; 57 hospitals in 19 upper-middle-income countries; and 90 hospitals in 27 low-income to lower-middle-income countries). The availability of five hospital facilities was inversely associated with mortality: ultrasound, CT scanner, critical care unit, opioid analgesia, and oncologist. After adjustment for case-mix and country income group, hospitals with three or fewer of these facilities (62 hospitals, 1294 patients) had higher mortality compared with those with four or five (adjusted odds ratio [OR] 3.85 [95% CI 2.58-5.75]; p&lt;0.0001), with excess mortality predominantly explained by a limited capacity to rescue following the development of major complications (63.0% vs 82.7%; OR 0.35 [0.23-0.53]; p&lt;0.0001). Across LMICs, improvements in hospital facilities would prevent one to three deaths for every 100 patients undergoing surgery for cancer.Interpretation Hospitals with higher levels of infrastructure and resources have better outcomes after cancer surgery, independent of country income. Without urgent strengthening of hospital infrastructure and resources, the reductions in cancer-associated mortality associated with improved access will not be realised

Urinary metals and metal mixtures and oxidative stress biomarkers in an adult population from Spain: The Hortega Study

INTRODUCTION: Few studies have investigated the role of exposure to metals and metal mixtures on oxidative stress in the general population. OBJECTIVES: We evaluated the cross-sectional association of urinary metal and metal mixtures with urinary oxidative stress biomarkers, including oxidized to reduced glutathione ratio (GSSG/GSH), malondialdehyde (MDA), and 8‑oxo‑7,8‑dihydroguanine (8-oxo-dG), in a representative sample of a general population from Spain (Hortega Study). METHODS: Urine antimony (Sb), barium (Ba), cadmium (Cd), chromium (Cr), cobalt (Co), copper (Cu), molybdenum (Mo), vanadium (V) and zinc (Zn) were measured by ICPMS in 1440 Hortega Study participants. RESULTS: The geometric mean ratios (GMRs) of GSSG/GSH comparing the 80th to the 20th percentiles of metal distributions were 1.15 (95% confidence intervals [95% CI]: 1.03-1.27) for Mo, 1.17 (1.05-1.31) for Ba, 1.23 (1.04-1.46) for Cr and 1.18 (1.00-1.40) for V. For MDA, the corresponding GMRs (95% CI) were 1.13 (1.03-1.24) for Zn and 1.12 (1.02-1.23) for Cd. In 8-oxo-dG models, the corresponding GMR (95% CI) were 1.12 (1.01-1.23) for Zn and 1.09 (0.99-1.20) for Cd. Cr for GSSG/GSH and Zn for MDA and 8-oxo-dG drove most of the observed associations. Principal component (PC) 1 (largely reflecting non-essential metals) was positively associated with GSSG/GSH. The association of PC2 (largely reflecting essential metals) was positive for GSSG/GSH but inverse for MDA. CONCLUSIONS: Urine Ba, Cd, Cr, Mo, V and Zn were positively associated with oxidative stress measures at metal exposure levels relevant for the general population. The potential health consequences of environmental, including nutritional, exposure to these metals warrants further investigation

Solve-RD: systematic pan-European data sharing and collaborative analysis to solve rare diseases.

For the first time in Europe hundreds of rare disease (RD) experts team up to actively share and jointly analyse existing patient's data. Solve-RD is a Horizon 2020-supported EU flagship project bringing together >300 clinicians, scientists, and patient representatives of 51 sites from 15 countries. Solve-RD is built upon a core group of four European Reference Networks (ERNs; ERN-ITHACA, ERN-RND, ERN-Euro NMD, ERN-GENTURIS) which annually see more than 270,000 RD patients with respective pathologies. The main ambition is to solve unsolved rare diseases for which a molecular cause is not yet known. This is achieved through an innovative clinical research environment that introduces novel ways to organise expertise and data. Two major approaches are being pursued (i) massive data re-analysis of >19,000 unsolved rare disease patients and (ii) novel combined -omics approaches. The minimum requirement to be eligible for the analysis activities is an inconclusive exome that can be shared with controlled access. The first preliminary data re-analysis has already diagnosed 255 cases form 8393 exomes/genome datasets. This unprecedented degree of collaboration focused on sharing of data and expertise shall identify many new disease genes and enable diagnosis of many so far undiagnosed patients from all over Europe
