Patients with acute exacerbations of chronic obstructive pulmonary disease (COPD) are often hospitalized in internal medicine units (IMUs), and their management is challenging due to a multiplicity factors affecting the outcome, such as correct patient classification, appropriate pharmacologic therapy, discharge, follow-up. In this context, standardized pathway (algorithm) for these patients was designed tested. Specifically, based on information collected through survey COPD IMUs, an...

Abstract Background The burden of cardiovascular (CV) complications in patients hospitalised for community-acquired pneumonia (CAP) is still uncertain. Available studies used different designs and criteria to define CV complications. We assessed the cumulative incidence acute during hospitalisation CAP Internal Medicine Units (IMUs). Methods This was a prospective study carried out 26 IMUs, enrolling consecutively CAP. Defined were: newly diagnosed heart failure, coronary syndrome, new onset...

We propose a model to describe lava tube formation, considering as Newtonian fluid moving downslope in rectangular channel. obtain flow velocity using an analytical steady‐state solution of the Navier‐Stokes equation. Shear stress is also calculated from for incompressible and isotropic fluid. A 2‐D with heat flux assigned at upper surface introduced cooling by radiation into atmosphere temperature. Lava crust considered plastic body, its rheology described through introduction yield...

Summary Few studies have addressed the topic of venous thromboembolism (VTE) in patients hospitalised rehabilitation facilities. This patient population is rapidly growing, and data aimed to better define VTE risk this setting are needed. Primary aim prospective observational study was evaluate frequency symptomatic, objectively confirmed a cohort unselected consecutive admitted facilities, after medical diseases or surgery. Further objectives were assess overall mortality, identify factors...

Venous thromboembolism (VTE) in hospitalized medically ill patients is a significant cause of morbidity and mortality. Guidelines suggest that VTE bleeding risk assessment models (RAMs) should be integrated into the clinical decision-making process on thromboprophylaxis. However, poor evidence available comparing use RAM versus judgement evaluating occurrence.

The introduction of protease inhibitors (PIs) gave a dramatic drop in AIDS-related opportunistic events, mainly due to induced immune reconstitution. Discontinuation prophylaxis against Pneumocystis carinii is considered safe when CD4 > 200 cells/mm3. Ideally, we should have specific functional tests for HIV-1-related decisions.

Bends in lava channels are often observed volcanic fields. The curvature of a channel affects flow dynamics and surface morphology may be trigger for the formation tube. We propose model to describe effects on velocity, shear stress crust at surface. Lava is described as Newtonian, homogeneous, isotropic incompressible fluid. steady-state solution Navier-Stokes equation found unidirectional flow, cylindrical coordinates. levees arcs concentric circumferences, with their centres origin...

We propose a model to explain lava tube formation by the growth of crust slabs from levees channel toward its center, involving solid surface fragments. The flow dynamics are described with steady state solution Navier‐Stokes equation in rectangular channel, for Newtonian, homogeneous, isotropic and incompressible fluid. cooling is mechanism heat conduction into atmosphere. presence taken account both dynamical thermal model.
