We use a variety of combinatorial techniques to prove several theorems concerning fractional dimension of partially ordered sets. In particular, we settle a conjecture of Brightwell and Scheinerman by showing that the fractional dimension of a poset is never more than the maximum degree plus one. Furthermore, when the maximum degree k is at least two, we show that equality holds if and only if ...

Objective: Patients’ satisfaction (PS) is recognized as an important emergency department service design and it has received a high interest and attention in the health management where many studies have focused on determining factors affecting PS in health-related circumstances. In this study, we aimed to examine PS in emergency department (ED) of the European Gaza Hospital (EGH) in the Gaza S...

PURPOSE To examine the 1-year prevalence and risk of emergency department (ED) use and ambulatory care-sensitive (ACS) ED use by nursing home (NH) residents with different levels of severity of cognitive impairment (CI). DESIGN AND METHODS We used multinomial logistic regression to estimate the effect of CI severity on the odds of any ED visit and any ACS ED visit in a 2006 national random sa...

The Argentinian author Silvina Ocampo (1903-1993) left us a vast body of works which are considered outstanding in many ways. In 1960, she published a short story, entitled "El médico encantador" (The Charming Physician), in the renowned literary magazine Sur. The central character of this piece is a family doctor named Albino Morgan, who had a secret truth: in any house he visited, all variety...

OBJECTIVE Violence is widespread in Australian emergency departments (ED) and most prevalent at triage. The aim of the present study was to identify the causes and common acts of violence in the ED perceived by three distinct groups of nurses. METHODS The Delphi technique is a method for consensus-building. In the present study a three-phase Delphi technique was used to identify and compare w...

BACKGROUND Uncontrolled asthma remains a frequent cause of emergency department (ED) visits and hospital admissions. Improper asthma inhaler device use is most likely one of the major causes associated with uncontrolled asthma and frequent ED visits. OBJECTIVES To evaluate the inhaler technique among asthmatic patients seen in ED, and to investigate the characteristics of these patients and f...

OBJECTIVES To estimate the incidence of erectile dysfunction (ED) in Brazilian men 40 to 69 years old at study entry during an average 2-year follow-up and study the effect of age, socioeconomic status, and medical conditions on the risk of developing ED. METHODS We analyzed data from a randomly sampled cohort of men living in Salvador, Bahia (Brazil), a racially diverse city with a populatio...

Background: Uncontrolled asthma remains a frequent cause of emergency department (ED) visits and hospital admissions. Improper asthma inhaler device use is most likely one of the major causes associated with uncontrolled asthma and frequent ED visits.

PURPOSE To identify the variables associated with severe action decisions (SADs) (unspecified accreditation term, warning status, probation status) by the Liaison Committee on Medical Education (LCME) regarding the accreditation status of established MD-granting medical education programs in the United States and Canada. METHOD The authors reviewed all LCME decisions made on full survey repor...
