The aim of the study was to determine the cost of prevention and treatment of pressure sores in an intensive care unit. We studied prospectively the cost of pressure area management for one year from April 1, 1990, collecting data on 2482 patient days. The 638 patients were divided into the 'prevention group' (525 patients), who did not have or develop pressure-related tissue injury, and the 'therapy group' (113 patients), who were admitted with or developed a sore. All items and personnel time employed in pressure area management for both groups of patients were documented and costed. Preventive measures for 525 patients cost £79 080, or £150 per patient. Measures for the 113 patients in the therapy group cost £36 200, or £320 per patient. The overall cost for both groups was £1 15 280, or 5% of the unit's annual budget. Only 5% of patients admitted without a sore developed pressure-related tissue damage. The use of special support surfaces contributed to the low incidence of pressure damage in what was considered to be a very high-risk patient population. This was without a significant increase in the mean cost per patient of providing pressure area care.

Impact of under-assisted ventilation on diaphragm function and structure in a porcine model.
Anesthesiology
January 2025
Department of Anesthesiology and Critical Care Medicine B (DAR B), Saint-Eloi Hospital, University Teaching Hospital of Montpellier, 80 avenue Augustin Fliche, 34295 Montpellier, France.
Background: Long-term controlled mechanical ventilation (CMV) in intensive care unit (ICU) induces ventilatory-induced-diaphragm-dysfunction (VIDD). The transition from CMV to assisted mechanical ventilation is a challenge that requires clinicians to balance over-assistance and under-assistance. While the effects of over-assistance on the diaphragm are well known, we aimed to assess the impact of under-assistance on diaphragm function and structure in piglet model with pre-existing VIDD (after long-term CMV) or without VIDD (short-term CMV).

Purpose: We sought to evaluate the relationship between blood vitamin A levels and myopia in adults aged ≥20 years in Korea.
Methods: We collected data of 15,899 participants aged ≥20 years from the Korean National Health and Nutrition Examination Survey. Participants underwent refraction tests to identify myopia and high myopia, and their blood pressure and obesity levels were measured.
Physical activity and metabolic syndrome in primary care patients in Spain.

Purpose: To determine the relationship between self-reported physical activity and the components of premorbid metabolic syndrome in patients treated in primary care according to sex.
Methods: Cross-sectional descriptive study conducted on a sample of 2,359 patients without cardiovascular disease or diabetes, included in the cohort of the IBERICAN study. Using ANOVA models and adjusting for age, economic status, employment situation, level of education, adherence to a Mediterranean diet, tobacco use and alcohol consumption, we estimated the association of the variables blood pressure, triglycerides, HDL cholesterol, blood glucose and waist circumference with the self-reported level of physical activity (sedentary, moderate, high, very high).
Understanding emotional and health indicators underlying the burnout risk of healthcare workers.
PLoS One

Department of Computer and Information Sciences, University of Northumbria, Newcastle Upon Tyne, United Kingdom.
Burnout of healthcare workers is of increasing concern as workload pressures mount. Burnout is usually conceptualised as resulting from external pressures rather than internal resilience and although is not a diagnosable condition, it is related to help seeking for its psychological sequelae. To understand how staff support services can intervene with staff heading for burnout, it is important to understand what other intrapsychic factors are related to it.
