COVID-19 infection in adult patients with hematological malignancies:a European Hematology Association Survey (EPICOVIDEHA)
Background: Patients with hematological malignancies (HM) are at high risk of mortality from SARS-CoV-2 disease 2019 (COVID-19). A better understanding of risk factors for adverse outcomes may improve clinical management in these patients. We therefore studied baseline characteristics of HM patients developing COVID-19 and analyzed predictors of mortality. Methods: The survey was supported by the Scientific Working Group Infection in Hematology of the European Hematology Association (EHA). Eligible for the analysis were adult patients with HM and laboratory-confirmed COVID-19 observed between March and December 2020. Results: The study sample includes 3801 cases, represented by lymphoproliferative (mainly non-Hodgkin lymphoma n = 1084, myeloma n = 684 and chronic lymphoid leukemia n = 474) and myeloproliferative malignancies (mainly acute myeloid leukemia n = 497 and myelodysplastic syndromes n = 279). Severe/critical COVID-19 was observed in 63.8% of patients (n = 2425). Overall, 2778 (73.1%) of the patients were hospitalized, 689 (18.1%) of whom were admitted to intensive care units (ICUs). Overall, 1185 patients (31.2%) died. The primary cause of death was COVID-19 in 688 patients (58.1%), HM in 173 patients (14.6%), and a combination of both COVID-19 and progressing HM in 155 patients (13.1%). Highest mortality was observed in acute myeloid leukemia (199/497, 40%) and myelodysplastic syndromes (118/279, 42.3%). The mortality rate significantly decreased between the first COVID-19 wave (MarchâMay 2020) and the second wave (OctoberâDecember 2020) (581/1427, 40.7% vs. 439/1773, 24.8%, p value < 0.0001). In the multivariable analysis, age, active malignancy, chronic cardiac disease, liver disease, renal impairment, smoking history, and ICU stay correlated with mortality. Acute myeloid leukemia was a higher mortality risk than lymphoproliferative diseases. Conclusions: This survey confirms that COVID-19 patients with HM are at high risk of lethal complications. However, improved COVID-19 prevention has reduced mortality despite an increase in the number of reported cases

High-resolution boreal winter precipitation projections over tropical America from CMIP5 models
Climate change projections for boreal winter precipitation in Tropical America has been
addressed by statistical downscaling (SD) using the principal component regression
with sea-level pressure (SLP) as the predictor variable. The SD model developed from
the reanalysis of SLP and gridded precipitation GPCC data, has been applied to SLP
outputs from 20 CGMS of CMIP5, both from the present climate (1971-2000) and for
the future (2071-2100) under the RCP2.6, RCP4.5, and RCP8.5 scenarios. The SD
model shows a suitable performance over large regions, presenting a strong bias only
in small areas characterized by very dry climate conditions or poor data coverage. The
difference in percentage between the projected SD precipitation and the simulated SD
precipitation for present climate, ranges from moderate to intense changes in rainfall
(positive or negative, depending on the region and the SD GCM model considered), as
the radiative forcing increases from the RCP2.6 to RCP8.5. The disparity in the GCMs
outputs seems to be the major source of uncertainty in the projected changes, while
the scenario considered appears less decisive. Mexico and eastern Brazil are the
areas showing the most coherent decreases between SD GCMs, while northwestern and southeastern South America show consistently significant increases. This
coherence is corroborated by the results of the ensemble mean which projects positive
changes from 10ÂșN towards the south, with exceptions such as eastern Brazil, northern
Chile and some smaller areas, such as the center of Colombia, while projected
negative changes are the majority found in the northernmost part.Departamento FĂsica Aplicada, Facultad de Ciencias, Universidad de Granad
