Experiences of Frequent Users of Emergency Departments in Health Care Setting in French-Speaking Switzerland: A Qualitative Study.

Aims: Frequent users of the emergency department (FUED; five ED visits or more per year) often have negative experiences in health care settings, potentially aggravating their health problems. Scarce research has explored FUED experiences in health care in Europe, none in Switzerland. Thus, this study aimed to conduct an in-depth exploration of FUED experiences in health care settings in Switzerland.

Perspectives of Frequent Users of Emergency Departments on a Case Management Intervention: A Qualitative Study.

Background: Effective management of frequent users of emergency departments (FUED) remains challenging. Case management (CM) has shown to improve patient quality of life while reducing ED visits and associated costs. However, little data is available on FUED's perception of CM outside of North America to further improve CM implementation.

[The health equity issues of an emergency department fee].

In June 2021, the Swiss parliament accepted a legislative proposal calling for the introduction of a fee to fight emergency department (ED) overcrowding. Although this issue remains a major challenge for health policies, the introduction of such a fee raises many questions, notably regarding health equity. However, other more equitable solutions exist: improving the case management of ED frequent users and improving coordination between ED and primary care.

Muscular HSP70 content is higher in elderly compared to young, but is normalized after 12 weeks of strength training.

Purpose: Aging is associated with increased myocellular stress and loss of muscle mass and function. Heat shock proteins (HSPs) are upregulated during periods of stress as part of the cells protective system. Exercise can affect both acute HSP regulation and when repeated regularly counteract unhealthy age-related changes in the muscle.

Cutting-edge microangio-CT: new dimensions in vascular imaging and kidney morphometry.

In the last decades, the contrast-enhanced micro-computed tomography (micro-CT) imaging of a whole animal kidney became increasingly important. The visualization was mainly limited to middle-sized vessels. Since modern desktop micro-CT scanners provide the necessary detail resolution, we developed an approach for rapid visualization and consistent assessment of kidney vasculature and glomeruli number.

Correlative Imaging of the Murine Hind Limb Vasculature and Muscle Tissue by MicroCT and Light Microscopy.

A detailed vascular visualization and adequate quantification is essential for the proper assessment of novel angiomodulating strategies. Here, we introduce an ex vivo micro-computed tomography (microCT)-based imaging approach for the 3D visualization of the entire vasculature down to the capillary level and rapid estimation of the vascular volume and vessel size distribution. After perfusion with μAngiofil®, a novel polymerizing contrast agent, low- and high-resolution scans (voxel side length: 2.

Zebrafish Caudal Fin Angiogenesis Assay-Advanced Quantitative Assessment Including 3-Way Correlative Microscopy.

Background: Researchers evaluating angiomodulating compounds as a part of scientific projects or pre-clinical studies are often confronted with limitations of applied animal models. The rough and insufficient early-stage compound assessment without reliable quantification of the vascular response counts, at least partially, to the low transition rate to clinics.

Objective: To establish an advanced, rapid and cost-effective angiogenesis assay for the precise and sensitive assessment of angiomodulating compounds using zebrafish caudal fin regeneration.

On the stability of large [4n]annulenes.

[reaction: see text] The stabilization energies (B3LYP/6-31G) of planar [4n]annulenes, evaluated by a new indene-isoindene isomerization method (see Abstract graphic), reveal that all 4n pi-electron rings larger than the energetically unfavorable cyclobutadiene are only slightly destabilized by the pi-electron interactions. Cyclooctatetraene prefers the "tub" conformation because of strain effects. Generally, the antiaromatic character of the larger systems with 4n pi-electrons is revealed best by their magnetic properties rather than by their energies.

Aromaticity of butalene and its homologues.

[structure: see text] The aromaticity of a series of fused cyclobutadiene systems is discussed in terms of their resonance energies. While there is considerable variation in their resonance energies per pi electron, all members of the series are calculated to be antiaromatic, though to a lesser degree than the parent cyclobutadiene.

Biologically oriented organic sulfur chemistry. 15. Organic disulfides and related substances. 41. Inhibition of the fungal pathogen Histoplasma capsulatum by some organic disulfides.

In an extension of promising inhibitory results in vitro against Histoplasma capsulatum, correlated earlier using substituent constants developed by regression analysis with 77 disulfides, one symmetrical and 14 unsymmetrical disulfides were prepared (3--17). About half were active in vitro against H. capsulatum (and one against Candida albicans).

Linear regression analysis of inhibitory potency of organic disulfides against Histoplasma capsulatum.

The Free-Wilson equations are derived for the case of symmetrical substitution and are applied, in four modifications, to in vitro inhibitory activity of 77 organic disulfides against Histoplasma capsulatum. Substituent constants are listed to aid in the design of new inhibitory agents against this human pathogen (and perhaps other fungal organisms).
