OBJECTIVES Analyze changes that have occurred among U.S. hospitals over a 17-year period, 1975 through 1991, in the percentage of Staphylococcus aureus resistant to beta-lactam antibiotics and associated with nosocomial infections. DESIGN Retrospective review. The percentage of methicillin-resistant S aureus (MRSA) was defined as the number of S aureus isolates resistant to either methicillin...

The indigenous South African mussel Perna perna gapes during periods of aerial exposure to maintain aerobic respiration. This behaviour has no effect on the body temperatures of isolated individuals, but when surrounded by conspecifics, beneficial cooling effects of gaping emerge. It is uncertain, however, whether the presence of the invasive mussel Mytilus galloprovincialis limits the ability ...

Following the end-Permian mass extinction, ammonoids were among the fastest clades to recover (Brayard et al., 2006), with at least two diversification phases during the Early Triassic. Diversification first peaked during the Smithian and was followed by a marked extinction phase at the end of this (sub-)stage. It was then followed by a second and massive evolutionary radiation during the Spath...

Although chromatography using a variety of novel bed configurations (e.g. fluidized beds, expanded beds, simulated moving beds, annular rotating beds, etc.) has been of recent interest, the majority of practical applications of analytical and preparative chromatography employ a stationary adsorbent bed into which a feed slug is charged periodically, similar to the technique first described by M...

INTRODUCTION Fair distribution of hospital beds across various regions is a controversial subject. Resource allocation in health systems rarely has focused on those who need it most and, in addition, is often influenced by political interests. The study assesses the distribution of hospital beds in different regions in Tehran, Iran, during 2010-2012. METHODS This cross-sectional study was con...

OBJECTIVES It has been suggested that since 1990, de-institutionalisation of mental healthcare in Western Europe has been reversed into re-institutionalisation with more forensic beds, places in protected housing services and people with mental disorders in prisons. This study aimed to identify changes in the numbers of places in built institutions providing mental healthcare in Western Europe ...

INTRODUCTION In recent years, the World Health Organization (WHO) has emphasized the importance of determining the equality of the distribution of healthcare resources. Inequalities in the healthcare system are one of the world's most important developmental challenges, and the inefficiencies that exist in healthcare systems are the most important reason for these challenges. Thermal burns are ...

OBJECTIVES To study the availability of neurosurgical intensive care for the traumatically brain injured in all 36 neurosurgical centres in the United Kingdom and Ireland receiving head injuries, the response times to referral, and the advice given to the referring hospitals. METHODS Telephone survey of receiving neurosurgeons regarding their bed status and their advice on three hypothetical ...

Correspondence to Professor Stefan Priebe; [email protected] ABSTRACT Objectives: It has been suggested that since 1990, de-institutionalisation of mental healthcare in Western Europe has been reversed into re-institutionalisation with more forensic beds, places in protected housing services and people with mental disorders in prisons. This study aimed to identify changes in the numbers of pl...

The concentration and distribution of a soil fumigant in the subsurface of field plots are two key factors in the determination of the fumigant efficacy. Subsurface concentrations of the biologically active compounds cis- and trans-1,3-dichloropropene (1,3-D) and chloropicrin (CP) were determined in soil at two adjacent injection traces and midpoint between the two traces in plastic-covered fie...
