The association between emergency department (ED) length of stay (EDLOS) with in-hospital mortality (IHM) in older patients remains unclear. This retrospective study aims to delineate the relationship EDLOS and IHM elderly patients. From ED (n = 383,586) who visited an urban academic tertiary care medical center from January 2010 December 2016, 78,478 (age ≥60 years) were identified stratified into three age subgroups: 60-74 (early elderly), 75-89 (late ≥90 years (longevous elderly). We...

Medical emergencies such as anaphylaxis may require immediate use of emergency medication. Because the low adherence chronic patients (ie, carrying anti-anaphylactic medication) and potentially long response time medical services (EMSs), alternative approaches to provide first aid are required. A smartphone-based community (ERC) was established for with allergies enable members share their automatic adrenaline injector (AAI) other who do not have AAI at onset anaphylactic symptoms. The is...

Abstract Background Child injury is a global public health problem. Children spend 25–50% of their daytime in school and risks accidents are high. The purpose this study to perform comprehensive analysis game-related injuries. Methods A nationwide dataset 36,002 events that occurred Israel between 2013 2019 were served by the National EMS, was used. relations different variables demonstrated using multidimensional frequency tables. Z-tests, chi-square tests, ANOVA J48 classification trees...

The ever-growing data acquisition speed represents a challenge for analysis in materials sciences general and the field of solar cells particular. This is because many unsupervised supervised learning algorithms require model re-derivation when presented with new samples which are markedly different from those used construction. Dynamic segmentation addresses this problem by continuously updating clusters structure, example, splitting old or opening ones, as presented. In work we present...

Background Smartphone-based emergency response apps are increasingly being used to identify and dispatch volunteer first responders (VFRs) medical emergencies provide faster aid, which is associated with better prognoses. Volunteers’ availability willingness respond uncertain, leading in recent studies rates of 17% 47%. Dispatch algorithms that select volunteers based on their estimated time arrival (ETA) without considering the likelihood may be suboptimal due a large percentage alerts...

This research reveals failure patterns of firms within the life sciences industry, by utilizing a cluster analysis approach. We uncover hidden in ceased and identify four distinct patterns: false start, promise, realistic management, walking dead. Each pattern represents unique combination firm characteristics that led to their downfall. The study sample consists 230 industry are registered Israel Venture Capital database. By examining similarities dissimilarities between patterns, aims...
