BACKGROUND Community-acquired pneumonia (CAP) remains a common and serious condition worldwide. The mortality from severe CAP remains high, and this has reached 50% in some series. This study was conducted to determine the mortality and predictors that contribute to in-hospital mortality for patients who exhibit CAP and acute respiratory failure that requires mechanical ventilation. METHODS W...

Previous reports have suggested a role for weather conditions and air pollution on the variability of sickle cell disease (SCD) severity, but large-scale comprehensive epidemiological studies are lacking. In order to evaluate the influence of air pollution and climatic factors on emergency hospital admissions (EHA) in SCD patients, we conducted an 8-year observational retrospective study in 22 ...

The OpenSees finite element software framework is extended for simulating fluid–structure interaction (FSI) by the particle finite element method (PFEM). At high levels of the framework, new classes handle meshing and interface detection of the fluid and structure domains and implement the fractional step method in order to solve the governing equations of linear momentum and mass conservation....

The Cox proportional hazards model has become the model of choice to use in analyzing the effects of covariates on survival data. However, this assumption has significant restrictions on the behavior of the conditional survival function. The accelerated failure time model, which models the survival time and covariates directly through regression, provides an alternative approach to interpret th...

BACKGROUND We recently reported that the pathologic mode of infiltrative growth (infiltrative [INF]-alpha, INF-beta, and INF-gamma) of colorectal liver metastases had characteristic morphologic findings, and furthermore showed that the INF type was a prognostic factor for disease-free survival after hepatic resection. HYPOTHESIS Preoperative computed tomographic (CT) findings of the liver nod...

Dynamic modulus characterizes the viscoelastic behavior of asphalt materials and is the most important input parameter for design and rehabilitation of flexible pavements using Mechanistic–Empirical Pavement Design Guide (MEPDG). Laboratory determination of dynamic modulus is very expensive and time consuming. To overcome this challenge, several predictive models were developed to determine dyn...

OBJECTIVES To investigate the association between delirium motor subtypes and hospital mortality and 12-month mortality in hospitalized older adults. DESIGN Prospective cohort study conducted from 2009 to 2015. SETTING Geriatric ward of a university hospital in Sao Paulo, Brazil. PARTICIPANTS We included 1,409 consecutive admissions of acutely ill patients aged 60 years and over. We exclu...

the performance of different yield loss models from an exponential family was evaluated in safflower-redroot pigweed systems in two field experiments conducted during 2007 and 2008 growing seasons at the research field of agricultural college of shiraz university, iran. the yield loss of safflower was recorded as relative yield loss in experimental plots laid out in split plot design with three...

Different models with various approaches to strategic positioning have been employed to define it in various industries. As one of the powerful models, BSC analyses all aspect of organization evenly. In this study BSC is used as an instrument to make Shiraz University more efficient in implementing strategic and performance or supporting their strategic plan. Therefore this study aims to desig...
