Biol Res 2018 Sep 4;51(1):32. Epub 2018 Sep 4.

Circulating Tumor Cell Unit, Faculty of Medicine, University Finis Terrae, Av Pedro de Valdivia 1509, Providencia, Santiago, Chile.

Minimal residual disease is that not detected by conventional imaging studies and clinically the patient remains disease free. However, with time these dormant cells will awaken and disease progression occurs, resulting in clinically and radiological detectable metastatic disease. This review addresses the concept of tumor cell dissemination from the primary tumor, the micrometastatic niche and tumor cell survival and finally the clinical utility of detecting and characterizing these tumor cells in order to guide management decisions in treating patients with prostate cancer.

[Co-production of OXA-48 and NDM-1 Carbapenemases in Providencia rettgeri: the first report].

Mikrobiyol Bul 2018 Jul;52(3):300-307

Inonu University Faculty of Medicine, Department of Infectious Diseases and Clinical Microbiology, Malatya, Turkey.

Our country is the epicenter of the OXA-48-like carbapenemase-producing Klebsiella and Escherichia coli; and in the recent years, the concern has been increasing due to both spreading of this resistance to other members of Enterobacteriaceae family and acquiring other carbapenemases by the OXA-48-producing strains. In this study, OXA-48 and NDM-1 co-production was presented in Providencia rettgeri. Two P. Read More

A simple model for estimating changes in rainfall erosivity caused by variations in rainfall patterns.

Environ Res 2018 Nov 6;167:515-523. Epub 2018 Aug 6.

Departamento de Ingeniería Hidráulica y Ambiental, Pontificia Universidad Católica de Chile, Av. Vicuña Mackenna 4860, Macul, Santiago, Chile; Centro de Desarrollo Urbano Sustentable CONICYT/FONDAP/15110020, El Comendador 1916, Providencia, Santiago 7520245, Chile. Electronic address:

A major challenge when coupling soil loss models with precipitation forecasts from Global Circulation Models (GCMs) is that their time resolutions do not generally agree. Precipitation forecasts from GCM must be scaled down; however, the distribution of the rainfall intensity, which can affect soil loss as much as precipitation amounts, is usually not considered in this process. Therefore, the objective of this study was to develop a statistical equation for computing event-based rainfall erosivity under changing precipitation patterns using the least amount of information possible.

Campus Bio-Medico, Unit of Cardiology, University of Rome, Rome, Italy.

Background: Many patients requiring cardiac implantable electronic device (CIED) implantation are on long-term oral anticoagulant therapy. While continuation of warfarin has been shown to be safe and reduce bleeding complications compared to interruption of warfarin therapy and heparin bridging, it is not known which novel oral anticoagulants (NOAC) regimen (interrupted vs uninterrupted) is better in this setting.

Methods: One-hundred and one patients were randomized to receive CIED implantation with either interrupted or uninterrupted/continuous NOAC therapy before surgery. Read More
