    Funder: European Society of Intensive Care Medicine; doi: http://dx.doi.org/10.13039/501100013347Funder: Flemish Society for Critical Care NursesAbstract: Purpose: Intensive care unit (ICU) patients are particularly susceptible to developing pressure injuries. Epidemiologic data is however unavailable. We aimed to provide an international picture of the extent of pressure injuries and factors associated with ICU-acquired pressure injuries in adult ICU patients. Methods: International 1-day point-prevalence study; follow-up for outcome assessment until hospital discharge (maximum 12 weeks). Factors associated with ICU-acquired pressure injury and hospital mortality were assessed by generalised linear mixed-effects regression analysis. Results: Data from 13,254 patients in 1117 ICUs (90 countries) revealed 6747 pressure injuries; 3997 (59.2%) were ICU-acquired. Overall prevalence was 26.6% (95% confidence interval [CI] 25.9–27.3). ICU-acquired prevalence was 16.2% (95% CI 15.6–16.8). Sacrum (37%) and heels (19.5%) were most affected. Factors independently associated with ICU-acquired pressure injuries were older age, male sex, being underweight, emergency surgery, higher Simplified Acute Physiology Score II, Braden score 3 days, comorbidities (chronic obstructive pulmonary disease, immunodeficiency), organ support (renal replacement, mechanical ventilation on ICU admission), and being in a low or lower-middle income-economy. Gradually increasing associations with mortality were identified for increasing severity of pressure injury: stage I (odds ratio [OR] 1.5; 95% CI 1.2–1.8), stage II (OR 1.6; 95% CI 1.4–1.9), and stage III or worse (OR 2.8; 95% CI 2.3–3.3). Conclusion: Pressure injuries are common in adult ICU patients. ICU-acquired pressure injuries are associated with mainly intrinsic factors and mortality. Optimal care standards, increased awareness, appropriate resource allocation, and further research into optimal prevention are pivotal to tackle this important patient safety threat

    Objetivo. Descrever os valores de referĂȘncia para chumbo em sangue em uma população urbana do MunicĂ­pio de Londrina, Estado do ParanĂĄ, Brasil. MĂ©todos. A população de referĂȘncia foi constituĂ­da por 520 voluntĂĄrios adultos avaliados de novembro de 1994 a dezembro de 1996. Os critĂ©rios de exclusĂŁo foram: exposição ocupacional ao chumbo, exposição atravĂ©s de hĂĄbitos, fumar mais de 10 cigarros por dia e morar perto de indĂșstrias ou de locais que utilizam o chumbo em seus processos produtivos. TambĂ©m foram excluĂ­dos indivĂ­duos com valores de exames clĂ­nicos e laboratoriais fora da normalidade, doenças crĂŽnicas e distĂșrbios cardiovasculares. Os teores de chumbo em sangue foram determinados por espectrofotometria de absorção atĂŽmica com chama de ar-acetileno. O limite de detecção obtido foi 1,23 mig/dL. ApĂłs as anĂĄlises de chumbo em sangue, foram determinados valor mĂ­nimo, primeiro quartil, mediana, terceiro quartil e valor mĂĄximo; mĂ©dia geomĂ©trica; intervalo de confiança de 95%; intervalo experimental; e valor de referĂȘncia. Resultados. Os valores de referĂȘncia para plumbemia variaram de 1,20 a 13,72 mig/dL. A mĂ©dia geomĂ©trica foi igual a 5,5 mig/dL. ConclusĂ”es. Em geral, os valores obtidos no presente estudo sĂŁo mais baixos do que aqueles obtidos em outros paĂ­ses. Estudos adicionais deveriam enfocar a obtenção de valores de referĂȘncia em outras populaçÔes brasileiras que vivem em regiĂ”es mais industrializadas.<br>Objective. To describe the reference values for lead in blood in an urban population in the city of Londrina, in the state of ParanĂĄ, Brazil. Materials and methods. The reference population was composed of 520 adult volunteers who were assessed from November 1994 to December 1996. Exclusion criteria were: occupational exposure to lead, exposure through personal habits or practices, smoking more than 10 cigarettes per day, and living near industrial plants or other places that use lead in their production processes. Also excluded were individuals with abnormal clinical or laboratory results or with chronic diseases or cardiovascular disorders. Lead blood levels were determined using air-acetylene flame atomic absorption spectrophotometry. The detectable limit was 1.23 mug/dL. After the analyses of lead in blood, the following values were determined: minimum value, first quartile, median, third quartile, and maximum value; geometric mean; 95% confidence interval; experimental interval; and reference value. Results. The reference values for lead in blood ranged from 1.20 mug/dL to 13.72 mug/ dL. The geometric mean was 5.5 mug/dL. Conclusions. In general, the values found in this study are lower than those that have been reported for other countries. Additional data should be gathered from Brazilian populations living in more-industrialized areas
