BACKGROUND: Antiretroviral treatment (ART) service scaling up has been practiced in the Ethiopia since 2006. Regardless of increasing number of primary health care centers providing the service, the existing hospitals are still overcrowded with ART service seeking patients may be because of the common belief that treatment outcome is better for hospital patients than those treated at the primary health centers. However, documented evidence comparing the treatment outcome for the two categories of health facilities is scarce in the study setting...

Cardiovascular risk prediction has developed significantly during recent years, as cardiovascular disease prevention guidelines recommend risk scores to identify patients at high and low risk. Where novel biomarkers were identified in recent years, it is simply impractical and expensive to perform laboratory testing as part of screening for non-communicable diseases in low- and middle-income countries. As part of a broader consortium we compared the ranking performance of a simple, non-laboratory-based risk score to laboratory-based scores in various South African populations...

INTRODUCTION: Caffeine is an adrenergic antagonist that enhances neuronal activity. Psychological stress depresses cognitive function. AIM: To investigate the effects of acute and chronic low dose caffeine on anxiety-like behavior and cognitive functions of acute or chronic psychological stressed rats. MATERIAL-METHOD: Acute or chronic caffeine (3mg/kg) was administered to male Sprague Dawley rats (200-250g, n=42) before acute (cat odor) and chronic variable psychological stress (restraint overcrowding stress, elevated plus maze, cat odor, forced swimming) induction...

Overcrowding in emergency departments generates potential inefficiencies. Using regional administrative data, we investigate the impact that an increase in the accessibility of primary care has on emergency visits in Italy. We consider two measures of avoidable emergency visits recorded at list level for each General Practitioner. We test whether extending practices' opening hours to up to 12 hours/day reduces the inappropriate utilization of emergency services. Since subscribing to the extension program is voluntary, we account for the potential endogeneity of participation in a count model for emergency admissions in two ways: first, we use a two-stage residual inclusion approach...

Commonly thought of as a disease of poverty and overcrowding in resource-poor settings globally, scabies is also an important public health issue in residential care facilities for the elderly (RCFE) in high-income countries such as the UK. We compared and contrasted current local Health Protection Team (HPT) guidelines for the management of scabies outbreaks in RCFE throughout England. We performed content analysis on 20 guidelines, and used this to create a quantitative report of their variation in key dimensions...

The South African health care system is embedded in a background of racial subordination and sexual violence against girls and women and of hierarchical male authority from youth to adulthood. Low wages, unemployment, urban overcrowding, inadequate sanitation, malnutrition, crime, and violence have contributed to economic and health inequality. With more health-insured whites than blacks and the proportion of gross national product spent on health care slowly increasing, two-thirds of health expenditures have been consumed by the private sector at a time when the cost of health insurance has risen to more than 3 times the rate of the consumer price index...

Companion animal overpopulation is a growing problem in the United States. In addition to strays, an average of 324,500 nonhuman animals are relinquished to shelters yearly by their caregivers due to family disruption (divorce, death), foreclosure, economic problems, or minor behavioral issues. As a result, estimates of animals in shelters range from 3 million to 8 million, and due to overcrowding, euthanasia is common. This analysis seeks to determine the appropriate pricing mechanisms to clear animal shelters of dogs in the manner most desirable-that is, through adoption...

A novel photo-responsive nano-container was successfully constructed based on well-defined vesicles formed by an amphiphilic overcrowded alkene switch. The nano-container could adjust its inner volume in reversible photo/heat controlled mode, which could show potential in remote drug delivery systems.

For insects that aggregate on host plants, both attraction and antiaggregation among conspecifics can be important mechanisms for overcoming host resistance and avoiding overcrowding, respectively. These mechanisms can involve multiple sensory modalities, such as sound and pheromones. We explored how acoustic and chemical signals are integrated by the bark beetle Dendroctonus valens to limit aggregation in China. In its native North American range, this insect conducts nonlethal attacks on weakened trees at very low densities, but in its introduced zone in China, it uses mixtures of host tree compounds and the pheromone component frontalin to mass attack healthy trees...

BACKGROUND: Observation units (OUs) have been shown to reduce emergency department (ED) lengths of stay (LOS) and admissions. Most published studies have been on OUs managing single complaints. OBJECTIVE: Our aim was to determine whether an OU reduces ED LOS and hospital admission rates for adults with a variety of presenting complaints. METHODS: We comparatively evaluated two hospitals in British Columbia, Canada (hereafter ED A and ED B) using a pre-post design...

Controlling the excited-state properties of light driven molecular machines is crucial to achieving high efficiency and directed functionality. A key challenge in achieving control lies in unravelling the complex photodynamics and especially in identifying the role played by dark states. Here we use the structure-sensitivity and the high time-resolution of UV-pump/IR-probe spectroscopy, to build a detailed and comprehensive model of the structural evolution of light driven molecular rotors. The photodynamics of these chiral overcrowded alkene derivatives are determined by two close-lying excited electronic states...

The rotational speed of an overcrowded alkene-based molecular rotary motor, having an integrated 4,5-diazafluorenyl coordination motif, can be regulated allosterically via the binding of metal ions. DFT calculations have been used to predict the relative speed of rotation of three different (i.e., zinc, palladium, and platinum) metal dichloride complexes. The photochemical and thermal isomerization behavior of these complexes has been studied in detail using UV-vis and (1)H NMR spectroscopy. Our results confirm that metal coordination induces a contraction of the diazafluorenyl lower half, resulting in a reduction of the steric hindrance in the "fjord" region of the molecule, which causes an increase of the rotational speed...

BACKGROUND: Emergency department (ED) overcrowding is frequently described in terms of input- throughput and output. In order to reduce ED input, a concept called primary triage has been introduced in several Swedish EDs. In short, primary triage means that a nurse separately evaluates patients who present in the Emergency Department (ED) and either refers them to primary care or discharges them home, if their complaints are perceived as being of low acuity. The aim of the present study is to elucidate whether high levels of in-hospital bed occupancy are associated with decreased permeability in primary triage...

Nationally, hospital emergency departments are met with challenges because of increasing patient demands, overcrowding, and the need to protect patient safety. It is imperative that frontline emergency department nurses are prepared to meet the complex needs of diverse patient populations by having appropriate continuing education, training, and institutional resources. Professional certification is associated with improved patient safety, higher organizational performance scores, professional growth, and credibility among nurses...

BACKGROUND: Brazil's National Tuberculosis Control Program seeks to improve tuberculosis (TB) treatment in vulnerable populations. Slum residents are more vulnerable to TB due to a variety of factors, including their overcrowded living conditions, substandard infrastructure, and limited access to healthcare compared to their non-slum dwelling counterparts. Directly observed treatment (DOT) has been suggested to improve TB treatment outcomes among vulnerable populations, but the program's differential effectiveness among urban slum and non-slum residents is not known...
