Liraglutide for the treatment of obesity among patients with hidradenitis suppurativaLiraglutida en el tratamiento de la obesidad en pacientes con hidradenitis supurativa / Liraglutide for the treatment of obesity among patients with hidradenitis suppurativa Liraglutida en el tratamiento de la obesidad en pacientes con hidradenitis supurativa

Background and aims: Hidradenitis suppurativa (HS) is associated with obesity. Weight loss is frequently reflected in an amelioration in the severity of the lesions. Case reports have suggested that liraglutide might improve not only weight but also skin. We aimed to study the effects of liraglutide 3mg in patients with obesity and HS on metabolic and dermatological parameters. Methods: 14 patients started treatment with liraglutide for 3 months. Severity of the lesions was evaluated using the Hurley Staging System and quality of life with the DLQI (Dermatology Quality Index). Results: There was a significant reduction in BMI (39.3±6.2 vs 35.6±5.8; p=0.002), waist circumference (121.3±19.2 vs 110.6±18.1cm; p=0.01), CRP (4.5±2.2 vs 3±2.1mg/L; p=0.04), homocysteine (16.2±2.9 vs 13.3±3μmol/L; p=0.005) and plasma cortisol (15.9±4.8 vs 12.6±4.5μg/dL; p=0.007). Hurley (2.6±0.5 vs 1.1±0.3; p=0.002) and DLQI (12.3±2.8 vs 9.7±6.9; p=0.04) improved significantly. In multiple regression analysis, weight loss did not correlate with any inflammatory parameter or Hurley. Conclusions: Liraglutide 3mg is effective and safe among patients with HS and obesity. Long-term studies are mandatory to assess the effects of liraglutide on skin lesions and inflammatory markers among subjects with HS beyond weight loss.(AU)

Antecedentes y objetivos: La hidradenitis supurativa (HS) se asocia a la obesidad. La pérdida de peso frecuentemente comporta una mejora en la gravedad de las lesiones. Casos aislados han sugerido que la liraglutida podría mejorar no solo el peso sino también la piel. Nuestro objetivo fue estudiar los efectos de liraglutida 3mg en pacientes con obesidad y HS sobre los parámetros metabólicos y dermatológicos. Métodos: Catorce pacientes iniciaron tratamiento con liraglutida durante 3meses. La gravedad de las lesiones se evaluó mediante la Escala de Hurley y la calidad de vida con el Dermatology Quality Index (DLQI). Resultados: Hubo una reducción significativa en el IMC (39,3±6,2 vs 35,6±5,8; p=0,002), la circunferencia de cintura (121,3±19,2 vs 110,6±18,1cm; p=0,01), la PCR (4,5±2,2 vs 3±2,1mg/l; p=0,04), la homocisteína (16,2±2,9 vs 13,3±3μmol/l; p=0,005) y el cortisol plasmático (15,9±4,8 vs 12,6±4,5μg/dl; p=0,007). El Hurley (2,6±0,5 vs 1,1±0,3; p=0,002) y la DLQI (12,3±2,8 vs 9,7±6,9; p=0,04) mejoraron significativamente. En el análisis de regresión múltiple, la pérdida de peso no se correlacionó con ningún parámetro inflamatorio ni con el Hurley. Conclusiones: Liraglutida 3mg es eficaz y segura en pacientes con HS y obesidad. Serán necesarios estudios a largo plazo para evaluar los efectos de la liraglutida sobre las lesiones cutáneas y los marcadores inflamatorios en la HS más allá de la pérdida de peso.(AU)

Gut dysbiosis, inflammation and type 2 diabetes in mice using synthetic gut microbiota from diabetic humans / Disbiose intestinal, inflamação e diabetes tipo 2 em camundongos usando microbiota intestinal sintética de humanos diabéticos

Abstract The study was aimed to assess impact of high fat diet (HFD) and synthetic human gut microbiota (GM) combined with HFD and chow diet (CD) in inducing type-2 diabetes (T2D) using mice model. To our knowledge, this is the first study using selected human GM transplantation via culture based method coupled dietary modulation in mice for in vivo establishment of inflammation leading to T2D and gut dysbiosis. Twenty bacteria (T2D1-T2D20) from stool samples of confirmed T2D subjects were found to be morphologically different and subjected to purification on different media both aerobically and anerobically, which revealed seven bacteria more common among 20 isolates on the basis of biochemical characterization. On the basis of 16S rRNA gene sequencing, these seven isolates were identified as Bacteroides stercoris (MT152636), Lactobacillus acidophilus (MT152637), Lactobacillus salivarius (MT152638), Ruminococcus bromii (MT152639), Klebsiella aerogenes (MT152640), Bacteroides fragilis (MT152909), Clostridium botulinum (MT152910). The seven isolates were subsequently used as synthetic gut microbiome (GM) for their role in inducing T2D in mice. Inbred strains of albino mice were divided into four groups and were fed with CD, HFD, GM+HFD and GM+CD. Mice receiving HFD and GM+modified diet (CD/HFD) showed highly significant (P<0.05) increase in weight and blood glucose concentration as well as elevated level of inflammatory cytokines (TNF-α, IL-6, and MCP-1) compared to mice receiving CD only. The 16S rRNA gene sequencing of 11 fecal bacteria obtained from three randomly selected animals from each group revealed gut dysbiosis in animals receiving GM. Bacterial strains including Bacteroides gallinarum (MT152630), Ruminococcus bromii (MT152631), Lactobacillus acidophilus (MT152632), Parabacteroides gordonii (MT152633), Prevotella copri (MT152634) and Lactobacillus gasseri (MT152635) were isolated from mice treated with GM+modified diet (HFD/CD) compared to strains Akkermansia muciniphila (MT152625), Bacteriodes sp. (MT152626), Bacteroides faecis (MT152627), Bacteroides vulgatus (MT152628), Lactobacillus plantarum (MT152629) which were isolated from mice receiving CD/HFD. In conclusion, these findings suggest that constitution of GM and diet plays significant role in inflammation leading to onset or/and possibly progression of T2D. .

Resumo O estudo teve como objetivo avaliar o impacto da dieta rica em gordura (HFD) e da microbiota intestinal humana sintética (GM) combinada com HFD e dieta alimentar (CD) na indução de diabetes tipo 2 (T2D) usando modelo de camundongos. Para nosso conhecimento, este é o primeiro estudo usando transplante de GM humano selecionado através do método baseado em cultura acoplada à modulação dietética em camundongos para o estabelecimento in vivo de inflamação que leva a T2D e disbiose intestinal. Vinte bactérias (T2D1-T2D20) de amostras de fezes de indivíduos T2D confirmados verificaram ser morfologicamente diferentes e foram submetidas à purificação em meios diferentes aerobicamente e anaerobicamente, o que revelou sete bactérias mais comuns entre 20 isolados com base na caracterização bioquímica. Com base no sequenciamento do gene 16S rRNA, esses sete isolados foram identificados como Bacteroides stercoris (MT152636), Lactobacillus acidophilus (MT152637), Lactobacillus salivarius (MT152638), Ruminococcus bromii (MT152639), Klebsiella aerogenides (MT152640), Bacteroides fragilis (MT152909), Clostridium botulinum (MT152910). Esses sete isolados foram, posteriormente, usados ​​como microbioma intestinal sintético (GM) por seu papel na indução de T2D em camundongos. Linhagens consanguíneas de camundongos albinos foram divididas em quatro grupos e foram alimentadas com CD, HFD, GM + HFD e GM + CD. Camundongos que receberam a dieta modificada com HFD e GM + (CD / HFD) mostraram um aumento altamente significativo (P < 0,05) no peso e na concentração de glicose no sangue, bem como um nível elevado de citocinas inflamatórias (TNF-α, IL-6 e MCP-1) em comparação com os ratos que receberam apenas CD. O sequenciamento do gene 16S rRNA de 11 bactérias fecais obtidas de três animais selecionados aleatoriamente de cada grupo revelou disbiose intestinal em animais que receberam GM. Cepas bacterianas, incluindo Bacteroides gallinarum (MT152630), Ruminococcus bromii (MT152631), Lactobacillus acidophilus (MT152632), Parabacteroides gordonii (MT152633), Prevotella copri (MT152634) e Lactobacillus Gasseri (MT152635D), foram tratadas com dieta modificada / CD) em comparação com as linhagens Akkermansia muciniphila (MT152625), Bacteriodes sp. (MT152626), Bacteroides faecis (MT152627), Bacteroides vulgatus (MT152628), Lactobacillus plantarum (MT152629), que foram isoladas de camundongos recebendo CD / HFD. Em conclusão, esses resultados sugerem que a constituição de GM e dieta desempenham papel significativo na inflamação levando ao início ou/e possivelmente à progressão de T2D.

Factores de riesgo para lesión renal aguda y terapia de reemplazo renal en pacientes con ventilación mecánica invasiva y COVID-19 / Risk factors for acute kidney injury and renal replacement therapy in severe critically ill patients with COVID-19 under invasive mechanical ventilation / Fatores de risco para lesão renal aguda e terapia de substituição renal em pacientes com ventilação mecânica invasiva e COVID-19

Resumen: Introducción: Desde diciembre de 2019, cuando el coronavirus respiratorio tipo 2 y el síndrome de insuficiencia respiratoria agudo (SDRA) por coronavirus tipo 2 (enfermedad por coronavirus 2019 [COVID-19]), se desarrolló en Wuhan, China, se ha convertido en una pandemia mundial, con 105'333.798 casos reportados el 04 de febrero de 2021. El 27 de febrero de 2020, la Ciudad de México reportó el primer caso de COVID-19, seguido de un crecimiento masivo de infecciones en todo el país. El número total de casos hasta hoy es de 1,886.245 con 81,223 casos activos estimados. El 18.77% de los pacientes han requerido hospitalización. El número total de muertes es de 164.290, con una estimación de 184.125. La lesión renal aguda (LRA) se encontró en 28% de los pacientes hospitalizados y en 46% de los pacientes en estado crítico, contribuyendo a una mortalidad significativamente mayor. La identificación de los factores de riesgo es importante para orientar la toma de decisiones tempranas en la clasificación de los pacientes para una monitorización más intensiva y prevenir el aumento de la mortalidad. Objetivo: Analizar el nivel de presión positiva al final de la espiración (PEEP) y factores inflamatorios que intervienen en el desarrollo de LRA e inicio de terapia de reemplazo renal (TRR) en pacientes con COVID-19. Material y métodos: Se realizó un estudio observacional, transversal y retrolectivo en pacientes con ventilación mecánica con SARS-CoV-2 que presentaron LRA y necesidad de TRR ingresados en la Unidad de Cuidados Intensivos Respiratorios del Centro Médico ABC. Se realizó análisis estadístico de medidas de tendencia central, descriptivo; para la identificación de la variable con mayor impacto para el desarrollo de LRA y terapia dialítica se realizó factor predictivo positivo, prueba Pearson para correlacionar con terapia de reemplazo renal. El estudio se aprobó por el Comité de Ética del Centro Médico ABC, Ciudad de México (Folio: ABC TAEABC-22-117). Resultados: Se analizaron en total 210 pacientes con ventilación mecánica con SARS-CoV-2 en la Unidad de Cuidados Intensivos Respiratorios del Centro Médico ABC, de los cuales, 51 (24.17%) desarrollaron LRA y 21 requirieron TRR. Se realizó una curva ROC para predecir el factor con mayor riesgo para presentar LRA, encontrando diferencias significativas en IL-6 con un área bajo la curva ROC de 0.909 (CI: 0.86-0.95). También se encontró significancia estadística en LRA a partir de PEEP por arriba de 13 cmH2O y terapia de reemplazo renal con PEEP > 15 cmH2O. Conclusión: Se encontró una correlación de niveles altos de PEEP y lesión renal aguda. Los marcadores inflamatorios al ingreso del paciente (específicamente IL-6) son parámetros adecuados para guiar el tratamiento; sin embargo, también son de utilidad para orientar a un pronóstico.

Abstract: Introduction: Since December 2019, when respiratory coronavirus type 2 and acute respiratory failure syndrome (ARDS) due to coronavirus type 2 (coronavirus disease 2019 [COVID-19]), developed in Wuhan, China, it has become a global pandemic, with 105,333,798 cases reported on February 4, 2021. On February 27, 2020, Mexico City reported the first case of COVID-19, followed by a massive growth of infections across the country. The total number of cases today is 1,886,245 with 81,223 estimated active cases. 18.77% of patients have required hospitalization. The total number of deaths is 164,290 with an estimated 184,125. AKI was found in 28% of hospitalized patients and 46% of critically ill patients, contributing to significantly higher mortality. Identification of risk factors is important to guide early decision making in triaging patients for more intensive monitoring and prevent increased mortality. Objective: To analyze the level of PEEP and inflammatory factors involved in the development of AKI and onset of RRT in patients with COVID-19. Material and methods: An observational, cross-sectional and retrolective study was performed in mechanically ventilated patients with SARS-CoV-2 who presented AKI and need for RRT admitted to the respiratory intensive care unit of the ABC Medical Center. Statistical analysis of measures of central tendency, descriptive; for the identification of the variable with the greatest impact for the development of AKI and dialytic therapy, a positive predictive factor was performed, Pearson test to correlate with renal replacement therapy. The study was approved by the ethics committee of the ABC Medical Center, Mexico City (Number: ABC TAEABC-22-117). Results: A total of 210 mechanically ventilated patients with SARS-CoV-2 in the Respiratory Intensive Care Unit of the ABC Medical Center were analyzed, of whom 51 patients (24.17%) developed AKI and 21 patients required RRT. An ROC curve was performed to predict the factor with the highest risk of developing AKI, finding significant differences in IL-6 with an area under the ROC curve of 0.909 (CI: 0.86-0.95). Statistical significance was found in AKI with PEEP above 13cmH2O and renal replacement therapy with PEEP > 15cmH2O. Conclusion: A correlation was found between high PEEP levels and acute kidney injury. Inflammatory markers at patient admission (specifically IL-6) are adequate parameters to guide treatment; however, they are also useful to guide prognosis.

Resumo: Introdução: Desde dezembro de 2019, quando o coronavírus respiratório tipo 2 e a síndrome do desconforto respiratório agudo do coronavírus (SDRA) (doença de coronavírus 2019 [COVID-19]), desenvolvida em Wuhan, China, tornou-se uma pandemia em todo o mundo, com 105'333.798 casos relatados em fevereiro 4, 2021. Em 27 de fevereiro de 2020, a Cidade do México relatou o primeiro caso de COVID-19, seguido por um crescimento maciço de infecções em todo o país. O número total de casos até o momento é de 1,886.245, com uma estimativa de 81,223 casos ativos. 18.77% dos pacientes necessitaram de internação. O número total de óbitos é de 164.290, com estimativa de 184.125. A LRA foi encontrada em 28% dos pacientes hospitalizados e 46% dos pacientes críticos, contribuindo para uma mortalidade significativamente maior. A identificação dos fatores de risco é importante para orientar a tomada de decisão precoce na classificação dos pacientes para monitoramento mais intensivo e para evitar o aumento da mortalidade. Objetivo: Analisar o nível de PEEP e fatores inflamatórios envolvidos no desenvolvimento de LRA e início de TRS em pacientes com COVID-19. Material e métodos: Realizou-se um estudo observacional, transversal e retroletivo em pacientes ventilados mecanicamente com SARS-CoV-2 que apresentavam LRA e necessidade de TRS internados na unidade de terapia intensiva respiratória do Centro Médico ABC. Foi realizado análise estatística de medidas de tendência central, descritiva; para identificar a variável de maior impacto no desenvolvimento de LRA e terapia dialítica, realizou-se fator preditivo positivo, o teste de Pearson para correlacionar com a terapia renal substitutiva. O estudo foi aprovado pelo comitê de ética do Centro Médico ABC, Cidade do México (Folio: ABC TAEABC-22-117). Resultados: Foram analisados um total de 210 pacientes com ventilação mecânica com SARS-CoV-2 na unidade de terapia intensiva respiratória do Centro Médico ABC, dos quais 51 pacientes (24.17%) desenvolveram LRA e 21 pacientes requereram TRS. Realizou-se uma curvatura ROC para prever o fator com maior risco para apresentar LRA encontrando diferenças significativas em IL-6 com uma área sob a curvatura ROC de 0.909(CI: 0.86-0.95). Da mesma forma, foi encontrada significância estatística na LRA por PEEP acima de 13 cmH2O e terapia renal substitutiva com PEEP > 15 cmH2O. Conclusão: Encontrou-se uma correlação entre níveis elevados de PEEP e lesão renal aguda. Marcadores inflamatórios na admissão do paciente (especificamente IL-6) são parâmetros adequados para orientar o tratamento; no entanto, eles também são úteis para orientar uma previsão.

Avaliação da influência dos marcadores inflamatórios na mortalidade de pacientes com AVC isquêmico / Evaluation of the influence of inflammatory markers on the mortality of patients with ischemic stroke

INTRODUÇÃO: À medida que a população envelhece e a expectativa de vida aumenta, a incidência global e a prevalência de AVC isquêmico tendem a aumentar significativamente. Nesse contexto, surge a necessidade de avaliar novos marcadores preditores de mortalidade, como a contagem absoluta de monócitos, relação linfócitos sobre monócitos, relação neutrófilos sobre linfócitos e níveis de proteína C reativa ultrassensível, que além de serem de fácil acesso e baixo custo, sugerem indicar desfecho no paciente com AVC agudo. OBJETIVOS: o objetivo deste estudo foi avaliar a associação dos marcadores inflamatórios com a mortalidade de pacientes com AVC isquêmico. MÉTODOS: trata-se de um estudo retrospectivo observacional a partir de prontuários eletrônicos e exames laboratoriais de pacientes com AVC isquêmico em uma unidade hospitalar de Cascavel/PR. Uma análise estatística descritiva foi conduzida para determinar o perfil dos pacientes segundo o desfecho e aplicado um modelo de regressão logística para verificar as variáveis associadas a mortalidade. Foram considerados significativos apenas os dados com p-valor <0,05. RESULTADOS: Dos 65 pacientes que foram admitidos no estudo, 50 receberam alta hospitalar e 15 foram a óbito no hospital. Entre os marcadores inflamatórios, a relação de neutrófilos sobre linfócitos (OR 1,55; p-valor <0,01) mostrou-se significativamente associada a maior chance de óbito. Os pacientes que faleceram apresentaram níveis superiores de PCR ultrassensível, maior contagem absoluta de monócitos, relação linfócitos sobre monócitos diminuída, e relação neutrófilos sobre linfócitos elevada. CONCLUSÃO: a relação de neutrófilos sobre linfócitos elevada pode estar significativamente associada ao desfecho desfavorável após um AVC isquêmico

IINTRODUCTION: As the population ages and life expectancy increases, the global incidence and prevalence of ischemic stroke tends to rise significantly. In this context, the need arises to evaluate new predictive markers of mortality, such as absolute monocyte count, lymphocyte-to-monocyte ratio, neutrophil-to-lymphocyte ratio and C-reactive protein (CRP) levels which, besides being easily accessible and affordable, manage to predict the outcome in patients with acute stroke. OBJECTIVES: the aim of this study was to evaluate the association between inflammatory markers and the mortality in ischemic stroke patients. METHODS: this is a retrospective observational study based on the analysis of electronic medical records and laboratory tests of in-patients who suffered an ischemic stroke in Cascavel/PR. A descriptive statistical analysis was conducted to determine patients´ profile according to the outcome and a logistic regression model was applied in order to verify the variables associated with mortality. Only data with a p-value <0,05 was considered. RESULTS: Out of the 65 patients who suffered an ischemic stroke included in the study, 50 were discharged and 15 died in hospital. Among the inflammatory markers, the neutrophil-tolymphocyte ratio (OR 1.55; p-value <0,01) was associated with a greater chance of death. Patients who died presented with higher levels of ultra-sensitive CRP, higher absolute monocyte count, lower lymphocyte-to-monocyte ratio and higher neutrophil-to- lymphocyte ratio. CONCLUSION: the elevated neutrophil-to-lymphocyte ratio may be significantly associated with negative outcomes following an ischemic stroke

RESUMEN Introducción: el conocimiento de la fisiopatología de la enfermedad ha revolucionado el enfoque tradicional en el tratamiento de las enfermedades causadas por virus respiratorios. Actualmente, se utilizan marcadores de la respuesta inflamatoria para diagnosticar, estratificar y predecir en muchos casos el comportamiento futuro del enfermo de covid-19. Objetivo: caracterizar la naturaleza de la relación entre el índice PO2/FiO2 y los parámetros inflamatorios y de coagulación en pacientes graves por la covid-19, en la región de Lombardía, Italia. Materiales y métodos: se realizó un estudio analítico, longitudinal, retrospectivo con 191 pacientes graves y críticos, que ingresaron con diagnóstico de covid-19 del 1 de abril al 20 mayo de 2020, en el Hospital Mayor de Crema, en la región de Lombardía, Italia. Resultados: las correlaciones evidenciadas fueron las siguientes: proteína C reactiva (-0,417) p = 0; procalcitonina (-0,152) p = 0,018; dímero D (-0,112) p = 0,061; fibrinógeno (-0,272) p = 0,000; creatinina plasmática (-0,320) p = 0,000; conteo de linfocitos (0,028) p = 0,000; troponina (-0,028) p = 0,142, y lactato (-0,191) p = 0,288. Conclusiones: los marcadores inflamatorios en la patogenia de la enfermedad juegan un rol capital, y el enfoque hacia este renglón del tratamiento médico antiinflamatorio de cualquier tipo es mandatorio. Se debe realizar un correcto monitoreo de la coagulación, usar heparinas de bajo peso molecular, así como mantener un adecuado soporte hemodinámico capaz de evitar las disoxias celulares que progresen al fallo multiorgánico (AU).

ABSTRACT Introduction: the knowledge of disease physiopathology has revolutionized the traditional approach in the treatment of diseases caused by respiratory viruses. Currently, the markers of inflammatory answer are used to diagnose, stratify and predict in many cases the future behavior of COVID-19 patients. Objective: to characterize the nature of the relationship between PO2/FiO2 (PAFI, Spanish acronym of PA= presión arterial [arterial pressure], FI=fracción inspirada [inspired fraction]) and coagulation and inflammatory parameters in seriously-ill patients with COVID-19, in the region of Lombardy, Italy. Materials and methods: a retrospective, longitudinal, analytic study was carried out in 191 severe and critical patients who were admitted in Hospadale Maggiori di Crema, in the region of Lombardy, Italy, with the diagnosis of COVID-19, in the period April 1st-May 20, 2020. Results: the evidenced correlations were the following: reactive C protein (-0.417) p=0; procalcitonin (PCT) (-0.152) p=0.018. D dimer (-0.112) p=0.061; Fibrinogen (-0.272) p=0.000; Plasma creatinine (-0.320) p=0.000; lymphocytes count (0,028) p=0,000; troponin (-0.028) p=0.142; and lactate (-0.191) p=0.288. Conclusions: inflammatory markers play a capital role in the disease pathogenesis, and approaching this item of the medical anti-inflammatory treatment is mandatory. It is useful to keep a correct coagulation screening, using low molecular weight heparins, and also keeping an adequate hemodynamic support able to avoid cell dysoxia progressing to multiorgan failure (AU).

Increased levels of ferritin on admission predicts intensive care unit mortality in patients with COVID-19

Background: The aim of this study was to evaluate hyperferritinemia could be a predicting factor of mortality in hospitalized patients with coronavirus disease-2019 (COVID-19).MethodsA total of 100 hospitalized patients with COVID-19 in intensive care unit (ICU) were enrolled and classified into moderate (n=17), severe (n=40) and critical groups (n=43). Clinical information and laboratory results were collected and the concentrations of ferritin were compared among different groups. The association between ferritin and mortality was evaluated by logistic regression analysis. Moreover, the efficiency of the predicting value was assessed using receiver operating characteristic (ROC) curve.ResultsThe amount of ferritin was significantly higher in critical group compared with moderate and severe groups. The median of ferritin concentration was about three times higher in death group than survival group (1722.25μg/L vs. 501.90μg/L, p<0.01). The concentration of ferritin was positively correlated with other inflammatory cytokines, such as interleukin (IL)-8, IL-10, C-reactive protein (CRP) and tumor necrosis factor (TNF)-α. Logistic regression analysis demonstrated that ferritin was an independent predictor of in-hospital mortality. Especially, high-ferritin group was associated with higher incidence of mortality, with adjusted odds ratio of 104.97 [95% confidence interval (CI) 2.63–4185.89; p=0.013]. Moreover, ferritin had an advantage of discriminative capacity with the area under ROC (AUC) of 0.822 (95% CI 0.737–0.907) higher than procalcitonin and CRP.ConclusionThe ferritin measured at admission may serve as an independent factor for predicting in-hospital mortality in patients with COVID-19 in ICU. (AU)

Antecedentes: El objetivo de este estudio fue evaluar si la hiperferritinemia podría ser un factor predictivo de la mortalidad en pacientes hospitalizados con enfermedad por coronavirus de 2019 (COVID-19).MétodosSe incluyó un total de 100 pacientes hospitalizados con COVID-19 en la unidad de cuidados intensivos (UCI), clasificándose como grupos moderado (n=17), grave (n=40) y crítico (n=43). Se recopiló la información clínica y de laboratorio, comparándose los niveles de ferritina entre los diferentes grupos. Se evaluó la asociación entre ferritina y mortalidad mediante un análisis de regresión logística. Además, se evaluó la eficacia del valor predictivo utilizando la curva ROC (receiver operating characteristic).ResultadosLa cantidad de ferritina fue significativamente superior en el grupo de pacientes críticos en comparación con el grupo de pacientes graves. La media de concentración de ferritina fue cerca de 3 veces superior en el grupo de muerte que en el grupo de supervivientes (1.722,25μg/L vs. 501,90μg/L, p<0,01). La concentración de ferritina guardó una correlación positiva con otras citoquinas inflamatorias tales como interleucina (IL)-8, IL-10, proteína C reactiva (PRC) y factor de necrosis tumoral (TNF)-α. El análisis de regresión logística demostró que la ferritina era un factor predictivo independiente de la mortalidad intrahospitalaria. En especial, el grupo de ferritina alta estuvo asociado a una mayor incidencia de la mortalidad, con un valor de odds ratio ajustado de 104,97 [intervalo de confianza (IC) del 95% 2,63-4.185,89; p=0,013]. Además, el valor de ferritina tuvo una ventaja de capacidad discriminativa en el área bajo la curva ROC (AUC) de 0,822 (IC 95% 0,737-0,907] superior al de procalcitonina y PRC.ConclusiónEl valor de ferritina medido durante el ingreso puede servir de factor independiente para prevenir la mortalidad intrahospitalaria en los pacientes de COVID-19 en la UCI.

Negative association between 25-hydroxyvitamin D and inflammatory markers in rheumatologic diseases / Asociación negativa entre 25-hidroxi vitamina D y los marcadores inflamatorios en enfermedades reumatológicas

Objective: The main purpose of this study was to evaluate serum 25-hydroxyvitamin D (25OHD) levels and its association with in"ammatory markers in patients with rheumatologic diseases (RD). Methods: A cross-sectional study in 154 women with RD (rheumatoid arthritis, spondyloarthritis and other connective tissue diseases) and 112 healthy individuals as a control group (CG) was carried out. Results: No differences in serum and urine calcium, serum phosphate, and urinary deoxypyridinoline were found. RD group had lower 25OHD and higher PTH compared to CG. RD group had higher C-reactive protein (CRP) and erythrocyte sedimentation rate (ESR) compared to CG. The overall mean level of 25OHD (ng/ml) was 26.3±12.0 in the CG and 19.4±6.8 in the RD group (p<0.0001). Moreover, CG had lower percentage of individuals with 25OHD de!ciency compared to RD (29.9% vs 53.2%). The femoral neck BMD was signi!cantly lower in postmenopausal RD women compared to CG. 25OHD levels signi!cantly correlated with ESR and CRP as in"ammatory markers. Age, BMI, presence of RD, and CRP were signi!cantly and negatively associated with 25OHD levels through linear regression analysis. According to univariate logistic regression analysis for 25OHD deficiency (<20 ng/ml), a significant and negative association with BMI, presence of RD, ESR and CRP were found. Conclusion: Patients with RD had lower 25OHD levels than controls and the presence of a RD increases by 2.66 the risk of vitamin D de!ciency. In addition, 25OHD has a negative correlation with ESR and CRP as in"ammatory markers. (AU)

Objetivo El objetivo principal de este estudio fue evaluar los niveles séricos de 25-hidroxivitamina D (25OHD) y su asociación con marcadores inflamatorios en enfermedades reumatológicas. Materiales y métodos: Se realizó un estudio transversal en 154 mujeres con enfermedades reumatológicas (artritis reumatoide, espondiloartritis y otras enfermedades del tejido conectivo) y 112 individuos sanos como grupo control (GC). Resultados: No se encontraron diferencias en el calcio sérico y urinario, el fosfato sérico y la desoxipiridinolina urinaria entre el GC y los sujetos con enfermedades reumatológicas. El grupo de pacientes con enfermedades reumatológicas tenía 25OHD más bajo y PTH más alto en comparación con el GC. Asimismo, el grupo de individuos con enfermedades reumatológicas tenía proteína C reactiva (PCR) y velocidad de eritrosedimentación (VES) más altas en comparación con el GC. El nivel de 25OHD (ng/ml) fue 26,3±12,0 en el GC y 19,4±6,8 en el grupo con enfermedades reumatológicas (p<0,0001). Además, el GC presentó un porcentaje menor de deficiencia de 25OHD en comparación con el grupo con enfermedades reumatológicas (29,9% vs 53,2%). La DMO del cuello femoral fue significativamente menor en las mujeres posmenopáusicas con enfermedades reumatológicas en comparación con el GC. La 25OHD correlacionó significativamente con la VES y la PCR como marcadores inflamatorios. El análisis de regresión lineal mostró que la edad, el IMC, la presencia de una enfermedad reumatológica y la PCR se asociaron significativa y negativamente con los niveles de 25OHD. Mientras que el análisis de regresión logística univariada mostró que la deficiencia de 25OHD (<20 ng/ml), se asoció significativa y negativamente con el IMC, la presencia de una enfermedad reumatológica, la VES y los niveles de PCR. Conclusiones: Los pacientes con enfermedades reumatológicas tenían niveles de 25OHD más bajos que los controles y la presencia de una enfermedad reumatológica aumenta en 2.66 el riesgo de deficiencia de vitamina D. Además, la 25OHD mostró correlación negativa con la VES y la PCR como marcadores inflamatorios. (AU)

Niveles de proteína C reactiva, bilirrubina y leucocitos como predictores de evolución anatomopatológica apendicular / Levels of C-reactive Protein, Bilirubin and Leucocytes as Predictors of Anotomopathological Appendicular Evolution

RESUMEN Introducción: La apendicitis aguda es la urgencia quirúrgica más frecuente en cualquier hospital del mundo. Aunque la mayoría de las veces se trata de un proceso intrabdominal banal, en ocasiones presenta una no desdeñable morbilidad y todavía en la época actual. Esta morbimortalidad se asocia, en la mayoría de los casos, a estados avanzados de afección apendicular. Objetivo: Predecir, con la cifra de bilirrubina, la proteína C reactiva y el recuento leucocitario, el estado del proceso apendicular agudo que presentaban los pacientes. Métodos: Se realizó un estudio observacional descriptivo en el que se han incluido aquellos pacientes intervenidos por sospecha de apendicitis aguda durante un periodo de 3 años (2017-2019) que cumplían los criterios de inclusión. Se analizó, como datos de laboratorio, la cifra de leucocitos, proteína C reactiva y bilirrubina. Resultados: Se observó un aumento de las cifras de proteína C reactiva y bilirrubina en los casos apendiculares avanzados, al igual que otros autores han evidenciado en la literatura. Así mismo, estos dos valores han resultado ser un factor de riesgo para presentar formas graves. El nivel de leucocitos sin embargo no ha demostrado relacionarse con la gravedad del proceso. Conclusiones: Vemos relevante el uso de los biomarcadores estudiados para predecir la gravedad apendicular con el objetivo de mejorar la asistencia en estos enfermos y disminuir las complicaciones derivadas del retraso terapéutico(AU)

ABSTRACT Introduction: Acute appendicitis is the most frequent surgical emergency in any hospital worldwide. Although most of the time it is a trivial intraabdominal process, sometimes it presents an unneglectable morbidity. This morbidity and the subsequent mortality are associated, in most cases, with advanced stages of an appendicular disease. Objective: To predict, using the value corresponding to bilirubin, C-reactive protein and leukocyte count, the state of acute appendicular process presented by patients. Methods: A descriptive observational study was carried out, including patients operated on for suspected acute appendicitis during a period of three years (2017-2019) and who met the inclusion criteria. The values for leukocyte count, C-reactive protein, and bilirubin were analyzed as laboratory data. Results: An increase in the values of C-reactive protein and bilirubin levels was observed in advanced appendicular cases, as other authors have shown in the medical literature. Likewise, these two values ​​have turned out to be a risk factor for presenting severe forms. However, the level of leukocytes has not been shown to be related to the severity of the process. Conclusions: We consider the use of the biomarkers studied as relevant to predict appendicular severity in view of improving care of these patients and reducing complications derived from therapeutic delay(AU)

Existe Alteração em Marcadores Inflamatórios em Estudantes de Medicina após Participação em Programa Mente-Corpo? / Is There Any Change in Inflammatory Markers in Medical Students after Participating in a Mind-Body Program?

RESUMO Introdução Estudantes do curso de Medicina estão expostos a carga elevada de estresse, desencadeada por terem que lidar com adoecimento e morte dos pacientes, extensa carga horária, privação de sono, competitividade, cobrança, responsabilidade e medo de errar, entre outros fatores. Algumas técnicas e práticas como a meditação têm sido utilizadas para auxiliar no manejo e redução de estresse, já sendo utilizadas em escolas médicas. O estresse pode ativar componentes do sistema inflamatório, desencadeando uma série de doenças. As desordens causadas pelo estresse podem ser mensuradas por meio de marcadores sorológicos, sendo que os biológicos são os principais utilizados. Objetivo Avaliar os efeitos de um programa de práticas mente-corpo, Redução de Estresse e Desenvolvimento da Empatia na Medicina (Redemed©), nos níveis dos marcadores pró- e anti-inflamatórios de estudantes de medicina. Metodologia Trata-se de um estudo quase-experimental, composto por 86 estudantes, sendo 44 do grupo intervenção, que participaram do programa Redemed© com oito encontros semanais, englobando técnicas de meditação e exercícios de vivências interpessoais, e 42 estudantes do grupo controle. Ambos os grupos, antes e após o curso, coletaram sangue para análise dos marcadores: proteína C reativa (PCR), fator de necrose tumoral-alfa (TNF-alfa), interleucina 06 (IL06) e interleucina 10 (IL10). Resultados Neste estudo, não foi observada alteração estatisticamente significativa nas citocinas pró-inflamatórias: PCR, TNF-α e IL06. No entanto, a IL-10, que é uma citocina anti-inflamatória, apresentou uma variação positiva e estatisticamente significativa (p: 0,009). Ela tem sido utilizada em estudos com práticas integrativas e complementares a fim de demonstrar seus benefícios. Conclusão O programa Redemed© parece beneficiar os estudantes de Medicina por meio da modulação inflamatória e como grupo de acolhimento no qual eles puderam compartilhar seu estresse e treinar estratégias de enfrentamento. Este estudo, mesmo não tendo encontrado diferença estatística significativa nos marcadores pesquisados, com exceção da IL10, traz à tona este tema importante do grande estresse vivenciado por estudantes de Medicina e a necessidade de as escolas médicas terem maior cuidado com seus alunos, acolhendo e trabalhando o estresse desses estudantes de forma a reduzir e gerenciar melhor este fator de adoecimento em suas vidas.

ABSTRACT Introduction Medical students are exposed to high stress levels, triggered by having to deal with their illness and death of their patients, extensive workloads, sleep deprivation, competition, having to fulfil demanding duties, responsibility, and fear of making mistakes, among other factors. Some techniques and practices, such as meditation, are used in medical schools to help manage and reduce stress. Stress can activate components of the inflammatory system, triggering a series of pathologies. The disorders caused by stress can be measured by means of serological markers, with biological markers being the main ones used. Objective. To evaluate the effects of a program of mind-body practices, Reduction of Stress and Development of Empathy in Medicine (REDEMED ©), on pro- and anti-inflammatory markers of medical students. Methodology This is a quasi-experimental study, composed of 86 students: 44 in the intervention group, who participated in the REDMED© program with eight-weekly meetings that included meditation techniques and exercises of interpersonal experiences, and 42 students in the control group. Before and after the course, blood was collected from both groups for analysis of the markers: C-reactive protein (CRP), tumor necrosis factor-alpha (TNF-alpha), interleukin-6 (IL06) and interleukin-10 (IL10). Results No statistically significant changes were observed in the proinflammatory cytokines CRP, TNF-α and IL06. However, IL-10, an anti-inflammatory cytokine, showed a positive and statistically significant variation (p: 0.009). It has been used in studies with integrative and complementary practices to demonstrate its benefits. Conclusion The REDEMED© program seems to benefit medical students through inflammatory modulation and as a group that provides a forum to share their stress and receive coaching in coping strategies. This study, even though it did not find a statistically significant difference in the markers studied, with the exception of IL10, raises the important theme of the high levels of stress that medical students experience, and the need for medical schools to take greater care of their students, addressing stress in order better manage it in their own lives.

The Combined Use of Pleural Fluid Parameters Improves Diagnostic Accuracy in Complicated Pleural Infection/Empyema. / La combinación de la determinación de parámetros bioquímicos del líquido pleural mejora la predicción diagnóstica de la infección pleural complicada/empiema.

INTRODUCTION: Identifying infectious pleural effusions (IPE) that will progress to complicated infection or empyema is challenging. The purpose of this study was to determine whether a model based on multiple biochemical parameters in pleural fluid can predict which IPEs will produce empyema. METHODS: A prospective study was performed of all cases of IPEs treated in our unit. IPEs were classified as uncomplicated or complicated (empyema). Logistic regression was used to estimate the risk for complicated pleural infection (empyema). A predictive model was developed using biochemical parameters in pleural fluid. Discriminatory power (areas under the ROC curve), calibration, and diagnostic accuracy of the model were assessed. RESULTS: A total of 177 patients were included in the study (74 with uncomplicated infectious pleural effusion, and 103 with complicated pleural effusion/empyema). The area under the curve (AUC) for the model (pH, lactate dehydrogenase and interleukin 6) was 0.9783, which is significantly superior to the AUC of the individual biochemical parameters alone (0.921, 0.949, and 0.837, respectively; P<.001 using all parameters). The rate of correct classification of infectious pleural effusions was 96% [170/177: 72/74 (97.3%) for uncomplicated and 98/103 (95.1%) for complicated effusion (empyema)]. CONCLUSION: The multiple-marker model showed better diagnostic performance for predicting complicated infectious pleural effusion (empyema) compared to individual parameters alone.

[Cord blood procalcitonin in the assessment of early-onset neonatal sepsis]. / Procalcitonina en sangre de cordón en la valoración del riesgo de sepsis neonatal precoz.

INTRODUCTION: Early diagnosis of early-onset neonatal sepsis (EONS) is essential to reduce morbidity and mortality. Procalcitonin (PCT) in cord blood could provide a diagnosis of infected patients from birth. OBJECTIVE: To study the usefulness and safety of a procedure for the evaluation of newborns at risk of EONS, based on the determination of PCT in cord blood. PATIENTS AND METHODS: Neonates with infectious risk factors, born in our hospital from October 2013 to January 2015 were included. They were processed according to an algorithm based on the values of cord blood procalcitonin (< 0.6ng/ml versus ≥0.6ng/ml). They were later classified as proved infection, probable, or no infection. RESULTS AND CONCLUSIONS: Of the 2,519 infants born in the study period, 136 met inclusion criteria. None of 120 cases with PCT<0.6ng/ml in cord blood developed EONS (100% negative predictive value). On the other hand, of the 16 cases with PCT ≥0.6ng/ml, 10 were proven or probably infected (62.5% positive predictive value). The sensitivity of the PCT against infection was 100%, with a specificity of 95.2% (area under the receiver operator curve 0.969). The incidence of infection in the study group was 7.4%, and 26.1% in cases with maternal chorioamnionitis. 21 newborn (15.4%) received antibiotic therapy. The studied protocol has shown to be effective and safe to differentiate between patients with increased risk of developing an EONS, in those where the diagnostic and therapeutic approach was more interventionist, versus those with less likelihood of sepsis, who would benefit from a more conservative management.

Efeito do tratamento periodontal não-cirúrgico sobre o controle glicêmico, mediadores inflamatórios e adipocinas em pacientes com diabetes mellitus tipo 2 e periodontite crônica severa / Effect of non-surgical periodontal treatment on glycemic control, inflammatory mediators and adipokines in patients with type 2 diabetes and severe chronic periodontitis

O objetivo do presente estudo foi avaliar o efeito do tratamento periodontal não cirúrgico sobre o controle glicêmico e os níveis séricos de adipocinas e mediadores inflamatórios em pacientes com periodontite crônica e diabetes mellitus tipo 2 (DM2). Foram selecionados 41 pacientes com periodontite crônica severa e com DM2, que foram aleatoriamente alocados em dois grupos: o grupo teste (21 pacientes, idade média de 58,1 ± 8,4 anos, 11 homens e 10 mulheres), que foram submetidos ao tratamento periodontal não cirúrgico; e o grupo controle (20 pacientes, idade média de 54,1 ± 9,9 anos, 14 homens e 6 mulheres), que permaneceram sem tratamento periodontal. Os parâmetros clínicos (profundidade de sondagem ­ PS, nível de inserção clínica ­ NIC, SS - sangramento à sondagem e índice de placa ­ IP), os laboratoriais (hemoglobina glicada ­ HbA1c, colesterol total ­ CT, HDL, LDL e triglicerídeos) e os marcadores inflamatórios (interleucinas - 1ß e -6, fator de necrose tumoral-α, resistina, leptina e adiponectina) foram avaliados inicialmente (dia 0) e 90 dias após a terapia periodontal. Os resultados obtidos indicaram uma redução na % dos sítios com SS, IP e nos sítios com PS ≥ 6mm no grupo teste (P <0.05). Os níveis de HbA1c, glicose estimada, IL-1ß, TNF-α e resistina também diminuíram significativamente neste grupo. Os demais marcadores não tiveram alterações significantes em ambos os grupos. Concluindo, o tratamento periodontal não cirúrgico da periodontite crônica severa foi associado à melhora do controle glicêmico e à diminuição nos níveis de IL-1ß, TNF-α e resistina após 3 meses, em pacientes com diabetes mellitus tipo 2.

The aim of this study was to evaluate the effects of non-surgical periodontal treatment on glycemic control, adipokines and systemic inflammatory mediators levels in patients with severe chronic periodontitis and diabetes mellitus type 2 (DM2). Fourty-one patients with severe chronic periodontitis and DM2 were randomly allocated in the test group (21 patients, mean age 58.1 ± 8.4 years, 11 men and 10 women) underwent nonsurgical periodontal treatment; and the control group (20 patients, mean age 54.1 ± 9.9 years, 14 men and 6 women) who remained untreated. The clinical parameters (probing depth - PD, clinical attachment level - CAL, BOP- bleeding on probing and plaque index - PI), laboratory (glycated hemoglobin - HbA1c, total cholesterol - TC, HDL, LDL and triglycerides) and inflammatory mediators (interleukin - 1ß and -6, tumor necrosis factor-α, resistin, leptin and adiponectin) were evaluated at baseline and 90 days after periodontal therapy. After 90 days, there was a reduction in the% of sites with BOP, PI and sites with PD ≥ 6 mm in the test group. HbA1c levels, estimated glucose, IL-1ß, TNF-α and resistin also significantly decreased in this group. There were no significant changes in the other markers in both groups. In conclusion, non-surgical periodontal treatment improved glycemic control in patients with severe chronic periodontitis and DM2. IL-1ß, TNF-α and resistin levels decreased significantly after 3 months of the treatment.

Avaliação de marcadores inflamatórios séricos em indivíduos com diabetes mellitus tipo 2 após tratamento periodontal intensivo não-cirúrgico: estudo clínico randomizado / Evaluation of serum inflammatory markers in individuals with type 2 diabetes mellitus after intensive non-surgical periodontal therapy: a randomized clinical trial effects

O objetivo deste trabalho foi comparar os efeitos sorológicos e clínicos de dois protocolos de terapias periodontais em indivíduos com diabetes tipo 2 (DMT2) e periodontite crônica. Foram analisados 36 pacientes, randomizados em dois grupos: um grupo recebeu terapia intensiva de raspagem e alisamento radicular (INT; n=18) e outro recebeu apenas raspagem supragengival (SUP; n=18). Os grupos foram avaliados quanto aos parâmetros clínicos periodontais e marcadores inflamatórios séricos, antes e após 6 meses do tratamento periodontal. O exame clínico periodontal avaliou: placa visível (IP), índice gengival (IG), supuração (SUPUR), profundidade clínica de sondagem (PCS) e nível clínico de inserção (NCI). Amostras sanguíneas foram obtidas para análise de marcadores inflamatórios e hemoglobina glicada (HbA1c). Os marcadores de inflamação avaliados foram: interleucina (IL)-1, IL-2, IL-4, IL-5, IL-6, IL-7, IL-8, IL-10, IL-12, IL-13, IL-17, fator estimulador de colônias granulocitárias (G-CSF), fator estimulador de colônias de granulócitos-macrófagos (GM-CSF), interferon- (IFN-), proteína quimiotática de monócito-1 (MCP-1), proteína inflamatória de macrófago-1 (MIP-1) e fator de necrose tumoral (TNF-), através do imunoensaio multiplex (Bioplex). Ambas as terapias resultaram na melhora de quase todos os parâmetros clínicos periodontais (p<0,05), com exceção do NCI (p=0,09) no grupo SUP. Não houve diferença significativa para os níveis de IL-1, IL-4, IL-5, IL-10, IL-13, MIP-1 e TNF- (p>0,05), após tratamento, em ambas as terapias. Houve redução significativa de IL-6 (p=0,01), IL-12 (p=0,04) e MCP-1 (p=0,02) no grupo INT e de GCS-F nos grupos SUP (p=0,04) e INT (p=0,01). Os níveis de IL-2, IL-7, IL-8, IL-17, GM-CSF e IFN- não foram detectados. A terapia INT tem um efeito benéfico na redução dos níveis séricos de IL-6, IL-12 e MCP-1, na redução de PCS em sítios profundos e no ganho de inserção quando comparado à terapia supragengival em um período de 6 meses...

The objective of this study was to compare the serological and clinical effects of two periodontal therapies in individuals with type 2 diabetes (T2DM) and chronic periodontitis. 36 patients were analyzed, randomized into two groups: one group received intensive t of scaling and root planing (INT, n=18) and another received only supragingival scaling (SUP, n=18). The groups were evaluated for periodontal parameters and serum inflammatory markers before and after 6 months of periodontal treatment. The periodontal parameters assessed were: visible plaque (PI), gingival index (GI), suppuration (SUP), probing pocket depth (PPD) and clinical attachment level (CAL). Blood samples were obtained for analysis of inflammatory markers and glycated hemoglobin (HbA1c). The inflammatory markers evaluated were: interleukin (IL)- 1 , IL- 2, IL -4, IL -5, IL -6, IL -7 , IL-8 , IL-10 , IL-12 , IL-13 , IL -17, granulocyte colony-stimulated factor (G -CSF), colony stimulating factor granulocyte-macrophage (GM -CSF), interferon - (IFN - ), monocyte chemotactic protein-1 (MCP-1) , macrophage inflammatory protein-1 (MIP-1 ) and tumor necrosis factor (TNF- ) through a multiplex immunoassay (Bioplex). Both therapies resulted in improvement of almost all periodontal clinical parameters (p<0.05), with the exception of the NCI in SUP group. There was no significant difference for (IL )- 1 , IL- 4, IL -5, IL-10 , IL-13 , MIP- 1 and TNF- after treatment for both therapies (p>0.05). A significant reduction was observed in IL-6 (p=0.01), IL-12 (p=0.04) and MCP-1 (p=0.02) levels for INT group and in GCS- F levels for SUP (p=0.04) and INT (p=0.01) groups. The levels of IL-2, IL -7, IL-8 , IL-17, GM- CSF and IFN- were not detectable. The INT therapy has a beneficial effect in reducing serum levels of IL-6, IL-12 and MCP-1, in reducing PPD of deep sites and in attachment gain when compared to SUP therapy considering a period of 6 months...

Incidence and predictive factors of delirium in hospitalised neurological patients.

INTRODUCTION: Delirium is a condition with a high prevalence in hospitalised patients (10%-30%), and it has important prognostic implications. There are few prospective studies of the incidence of delirium in Spain, and most of these were carried out in surgical wards or intensive care units. Our objective is to calculate the incidence of delirium in a neurological department and describe characteristics of affected patients. METHODS: Longitudinal descriptive study including all patients admitted to the neurology department in an 8-week period. The CAM score for diagnosing delirium was recorded on the first, second and fifth day of hospitalisation and we recorded demographic data, medical history, analytical data (including inflammatory markers), use of anticholinergic treatments, cognitive and functional state at admission, reason for admission, length of stay, and other events during hospitalisation. RESULTS: We studied 115 patients and found an incidence of delirium of 16.52%. There was a significant correlation between delirium and age, cognitive state at admission according to the Pfeiffer test, functional situation at admission according to the Canadian Neurological Scale, kidney failure, history of stroke, anticholinergic treatment, erythrocyte sedimentation rate, and C-reactive protein. These patients were also hospitalised for longer periods of time. CONCLUSIONS: These results confirm a high incidence of delirium in our geographical area. Although additional studies with larger samples are needed, we would like to emphasise the importance of several risk factors which may enable early detection of patients who are at risk for developing delirium during hospitalisation. This would permit preventive action and early treatment for these patients.
