Background: Bladder cancer (BC) is the most common of those affecting the urinary tract, and a significant proportion of the cases are attributable to tobacco use as well as occupational and environmental factors.

Objective: The aim of this study is to estimate the current incidence of BC in an industrialized area in northeastern Spain and to analyze its time trends over three decades from an ecological perspective.

Methods: Patients diagnosed with histologically confirmed primary BC, during 2018-2019, in an area in northeastern Spain (430,883 inhabitants) were included.

The SARS-CoV-2 pandemic, which affects the entire population in general, poses a special risk for patients with chronic kidney disease because of their immunosuppression status, advanced age and the coexistence of significant comorbidity.Renal patients undergoing hemodialysis run the risk not only of suffering but also of transmitting and spreading COVID-19 due to multiple factors, both procedural and logistical, associated with the process. These include the long duration of the technique, collective transfer to and from the centres, and the waiting time before performing the technique, aspects that make strict isolation difficult and therefore increase not only the risk of contagion between patients but also between specialist health professionals, which makes it more difficult to replace professionals.

Background: Tracheostomy is one of the most frequent techniques in intensive care units (ICU). Fiberoptic bronchoscopy (FB) is a safety measure when performing a percutaneous dilatational tracheostomy (PDT), but the controversy surrounding the routine use of FB as part of the procedure remains open. National surveys in some European countries showed that the use of FB is non-standardized.

We retrospectively evaluated 2879 hospitalized COVID-19 patients from four hospitals to evaluate the ability of demographic data, medical history, and on-admission laboratory parameters to predict in-hospital mortality. Association of previously published risk factors (age, gender, arterial hypertension, diabetes mellitus, smoking habit, obesity, renal failure, cardiovascular/ pulmonary diseases, serum ferritin, lymphocyte count, APTT, PT, fibrinogen, D-dimer, and platelet count) with death was tested by a multivariate logistic regression, and a predictive model was created, with further validation in an independent sample. A total of 2070 hospitalized COVID-19 patients were finally included in the multivariable analysis.

Background: The pOV plasmid isolated from the Pasteurella multocida strain PMOV is a new plasmid, and its molecular characterization is important for determining its gene content and its replicative properties in Pasteurellaceae family bacteria.

Methods: Antimicrobial resistance mediated by the pOV plasmid was tested in bacteria. Purified pOV plasmid DNA was used to transform E.
