Importance of blood pressure monitoring in the acute phase of stroke. An update.

INTRODUCTION: The evaluation of blood pressure (BP) is essential in the acute phase of stroke. Although ambulatory blood pressure monitoring (ABPM) is a validated method for BP control, there are few studies assessing the usefulness of ABPM in the acute phase of stroke. DEVELOPMENT: A systematic review was carried out according to the PRISMA criteria in the PubMed/Medline and Scopus databases. Those articles that analysed the use of ABPM in the first days after suffering a stroke from 1992 to 2022 were selected. Those articles focused on the post-acute or sequelae phase of the stroke, with a sample size of less than 20 and those where the primary objective was different from the defined one. A total of 28 articles were included. CONCLUSIONS: The use of ABPM in patients with recent stroke demonstrates that the normal circadian profile of BP is altered in more than two-thirds of patients and that this will be fundamentally conditioned by the haemodynamic changes that occur on autoregulation of cerebral blood flow, the type of stroke or the response to treatment. Furthermore, these changes in BP have prognostic implications and are correlated with functional status, stroke recurrence and mortality, among others. However, although they continue to be a growing area of research, new studies are needed to clarify the real role of this technique in patients with acute stroke.

Objetivo: caracterizar clínica y epidemiológicamente a los pacientes con enfermedad pulmonar obstructiva crónica. Métodos: estudio descriptivo retrospectivo trasversal, que incluyó pacientes adultos con diagnóstico de enfermedad pulmonar obstructiva crónica en un hospital universitario de Medellín. Material y métodos: la fuente de información fue secundaria a través de historias clínicas, el análisis se realizó en el programa Jamovi, empleando un análisis univariado. Resultados y discusión: se incluyeron 552 pacientes, la edad mediana fue 76 años con predominio del sexo femenino (56.7%). Respecto a la exposición a sustancias tóxicas respiratorias importantes en el desarrollo de la enfermedad, 24.1% consumían cigarrillo y 23% exposición a biomasa. Al momento del ingreso hospitalario 17.9% fueron clasificados con disnea grado IV; 74.1% recibió beta-agonistas de corta acción y antimuscarínicos de corta acción 60%; 11.6% requirió ingreso a las unidades de cuidados intensivos o especiales y 7.8% fallecieron durante la hospitalización. Conclusiones: se evidencia subdiagnóstico espirométrico de la enfermedad que puede estar relacionado con las limitaciones económicas, tecnológicas y de recurso humano capacitado, lo cual afecta el adecuado diagnóstico y manejo de la enfermedad, así como impacta la calidad de vida de los pacientes.

Objective: clinical and epidemiological characterization of patients with chronic obstructive pulmonary disease (COPD). Methods: a retrospective, cross-sectional, descriptive study, which included adult patients with a diagnosis of COPD in a university hospital in Medellín. Data sources were secondary, based on medical records. The Jamovi program was used to perform a univariate analysis. Results and discussion: 552 patients were included. Median age was 76 years with a female predominance (56.7%). Regarding exposure to major respiratory toxic substances implicated in the development of the disease, 24.1% were tobacco smokers and 23% were exposed to biomass smoke. At the time of hospital admission,17.9% were classified as having grade 4 dyspnea; 74.1% received short acting beta-agonists and 60% short-acting antimuscarinics,11.6% required intensive care unit or special care unit admission, and 7.8% died in hospital. Conclusions: under-diagnosis of COPD by spirometry may be related to economic, technological, and trained human resource limitations, which affect adequate diagnosis and management of the disease, as well as patient ́s quality of life.

Abordaje y tratamiento del ictus isquémico en la fase aguda / Management of acute ischemic stroke

El ictus isquémico es una enfermedad neurológica grave que precisa una atención urgente. Al ser una enfermedad dependiente del tiempo, la asistencia debe ser coordinada y eficaz para que ofrezca el tratamiento adecuado de la forma más precoz posible. El tratamiento de la fase aguda incluye unas medidas generales para garantizar la estabilidad hemodinámica del paciente, el uso de terapias de reperfusión (trombolíticos intravenosos y tratamiento endovascular mediante trombectomía mecánica) y la contribución a la protección cerebral mediante el control de presión arterial, glucemia, temperatura y oxigenación, así como prevenir complicaciones cerebrales y sistémicas. Se debe planificar de manera precoz el tratamiento rehabilitador del paciente. Para evitar las recurrencias precoces se recomienda tratamiento antitrombótico según la etiología del ictus y el control de los factores de riesgo vascular. Todas estas medidas tienen como objetivo revertir los síntomas iniciales, evitar que progrese la lesión, mejorar la situación funcional del paciente y evitar recurrencias (AU)

Ischemic stroke is a serious neurological condition that requires urgent attention. As a time-dependent disease, acute stroke management must be coordinated and effective to provide the best treatment as early as possible. The treatment of the acute phase of ischemic stroke includes general measures to ensure patient hemodynamic stability, the use of reperfusion therapies (intravenous thrombolytics and mechanical thrombectomy), improving cerebral protection by monitoring the homeostasis of certain variables as blood pressure, glycemia, temperature, or oxygenation, as well as preventing cerebral and systemic complications. Also, it is necessary an early planning of comprehensive rehabilitation. To prevent early recurrences, control of vascular risk factors and antithrombotic treatment is recommended. The management of patients with acute ischemic stroke aims to reverse initial symptoms, to prevent further brain damage, improve functional outcomes and avoid ischemic recurrences (AU)

Plasma D-dimer value corrected by inflammatory markers in patients with SARS-CoV-2 infection: Its prognostic value in the diagnosis of venous thromboembolism / Valor del dímero-D corregido por marcadores inflamatorios en pacientes con infección por SARS-CoV-2 en el diagnóstico de enfermedad tromboembólica venosa

Introduction:D-dimer levels are elevated in COVID 19 and they correlate to the levels of other inflammatory markers such us ferritin, fibrinogen and C-reactive protein. It may be possible to correct D-dimer value in function of inflammatory markers, thus identifying patients at higher risk of venous thromboembolism (VTE). Our objectives are estimating a corrected value of plasma D-dimer as a linear function of ferritin, C-reactive protein and fibrinogen and stablishing a cut-off point of high probability of VTE.Patients and methods:Age and sex matched case-control study of all patients diagnosed with COVID 19 and VTE between March and May 2020 in a tertiary hospital in Madrid (Spain). Using linear regression, the best predictive model will be estimated and residual D-dimer values will be obtained and analyzed using ROC curves to determine its discriminative performance.Results:Thirty-eight cases and seventy-six controls were included. There was 63.2% of men and mean age was 68.2. D-dimer was best predicted by a linear model including fibrinogen, ferritin and C-reactive protein. Using residual values, the optimal cutoff point was 2165ng/mL, with a sensitivity of 57.9% and specificity of 98.7%.Conclusion:It is possible to estimate a D-dimer corrected value in function of ferritin, C-reactive protein and fibrinogen. Using the observed and estimated value we can obtain a residual value that performs well as a screening method to detect patients who would benefit for further VTE diagnostic testing.(AU)

Abstract Sedimentation rate is an indirect inflammation measure, it rises when increase proteins (acute phase reactants) during inflammatory disorders, extreme high value (≥100mm / hour) has a high specificity for the diagnosis of infectious, neoplastic, and autoimmune diseases. Objective: To characterize inpatients with an extreme elevation of the sedimentation rate, and to establish the correlation between determinant factors and extreme sedimentation. Methods: Observational and cross-sectional study, including patients older than 18 years, with an extremely sedimentation rate, hospitalized in Hospital Pablo Tobon Uribe in Medellin city, during November of 2016 to June of 2018. Results: We selected 1007 patients from the data base, Infections were the most common diagnosis (743, 73.8%), and the main type were urinary tract infections (133, 13%). We evidence a negative correlation with the hemoglobin -0.092(0.155 a -0.029) and with the hematocrit -0.087(0.150 a -0.024), and a positive and weak significant correlation with the C-reactive protein 0.080 (0.014 a 0.146) p 0.02. Discussion: The infections, as in other studies, represent the main etiology associated with an extreme sedimentation. Different to other analyzed investigations, we observed a direct, weak and statistically significant correlation between the PCR and the extreme VSG. Conclusions: Infections were the main cause of extreme sedimentation rate. We evidence an inverse correlation between the blood sedimentation and the hemoglobin and the hematocrit, and a weak correlation with the C-reactive protein. MÉD.UIS.2021;34(3): 39-45.

Haptoglobin and its association with naturally occurring diseases in Holstein heifer calves / [Haptoglobina e sua associação com doenças ocorridas naturalmente em bezerras da raça Holandesa]

The present study evaluated the use of haptoglobin (Hp) as an indicator of health and performance in 166 Holstein heifer calves reared in an intensive production system. Calves were evaluated at D6-9; D10-13; D20-23; D35-38 and D65-68, corresponding to the days of life. The absence or presence of diseases was evaluated by physical examination and classification of scores. The performance parameters evaluated were body weight, height at withers and hind width. Hp was measured by spectrophotometric technique. The highest prevalence of diarrhea (59.4%; 98/165) was observed in D10-13, bovine respiratory disease (BRD) was on D35-38 (25.8%; 42/163), and umbilical inflammations in D6-D9 (7.8%; 13/166). Highest values of Hp were observed in animals with diarrhea (P=0.02), and umbilical inflammation (P=0.057), in comparison with the group of healthy calves. A significant negative correlation was observed between Hp and performance index. This protein presented an important relation with diarrhea and performance of the calves, opening perspectives on its utilization as a biomarker of diseases.(AU)

O presente estudo avaliou o uso da haptoglobina (Hp) como indicadora de sanidade e desempenho em 166 bezerras Holandesas criadas em um sistema de produção intensivo. As bezerras foram avaliadas nos momentos D6-9; D10-13; D20-23; D35-38 e D65-68, sendo estes correspondentes aos dias de vida. A ausência ou a presença de doenças foi avaliada por meio do exame físico e da classificação por escores. Os parâmetros de desempenho avaliados foram peso corporal, altura de cernelha e largura de garupa. A Hp foi mensurada por técnica espectrofotométrica. A maior prevalência de diarreia (59,4%; 98/165) foi observada em D10-13, doença respiratória bovina (DRB) ocorreu em D35-38 (25,8%; 42/163) e inflamações umbilicais em D6-D9 (7,8%; 13/166). O valor de Hp foi maior nos animais que apresentaram diarreia (P=0,02) e inflamações umbilicais (P=0,057), em comparação ao grupo de bezerras saudáveis. Houve correlação negativa significativa entre a Hp e os índices de desempenho. Essa proteína apresentou uma importante relação com a diarreia e com o desempenho das bezerras, abrindo perspectivas sobre a sua utilização como biomarcadora de doenças.(AU)

Correlation of serum acute-phase proteins with bone repair in rabbits (Oryctolagus cuniculus) submitted to partial radio ostectomy / Correlação do proteinograma sérico com a reparação óssea em coelhos (Oryctolagus cuniculus) submetidos à ostectomia parcial do rádio

ABSTRACT: Bone trauma triggers an acute inflammatory response, which can alter the serum concentration of acute-phase proteins (PFA). We aimed to evaluate the effectiveness of PFA measurement as a laboratory biomarker for inflammation related to bone regeneration. A partial ostectomy of the right radius was performed on 22 young male rabbits. The complete blood count, albumin, ceruloplasmin, haptoglobin, C-reactive protein, and transferrin levels were recorded and correlated with the radiographic evolution of bone healing. Statistically the best correlations with the inflammatory process and radiological findings were reported with haptoglobin and transferrin compared to the other measured PFAs. Haptoglobin and transferrin showed a maximum peak 24 and 36 hours after surgery, respectively. Transferrin displayed signs of decrease in the first 6 hours after surgery, in advance of the leukocyte response. The measurement of acute-phase proteins proved to be viable, considering the conditions in which the present study was carried out. Among all variables studied, haptoglobin and transferrin showed best correlation with the inflammatory process of bone healing. Additional studies are needed to determine the sensitivity of acute-phase proteins as predictors of complications in the treatment of fractures.

RESUMO: Os traumas ósseos desencadeiam resposta inflamatória aguda e consequentemente alteram a concentração sérica das proteínas de fase aguda (PFA), podendo essas representarem um parâmetro para avaliação da evolução do processo inflamatório relacionado à cicatrização óssea, assim como complicações. Objetivou-se avaliar a inter-relação da mensuração de PFAs com a repação óssea em coelhos submetidos à ostectomia parcial do rádio. Foram utilizados 22 coelhos, machos, jovens (160 a 180 dias) e peso médio (3,8 ± 0,3). Para acompanhamento da evolução do processo inflamatório foram realizados hemograma completo e mensuração de albumina, ceruloplasmina, haptoglobina, proteína C reativa e transferrina, além do acompanhamento radiológico. Foi observado a melhor correlação da haptoglobina e da transferrina junto ao processo inflamatório e achados radiológicos frente às demais PFAs mensuradas. A haptoglobina apresentou pico máximo 24 horas do pós-operatório e a transferrina após 36 horas, entretanto, essa última já mostrou indícios de diminuição nas primeiras 6 horas do pós-cirúrgico, antecipadamente à resposta leucocitária. Nas condições em que o presente estudo foi realizado, a mensuração das proteínas de fase aguda mostrou-se factível. Das proteínas estudadas, a haptoglobina e transferrina foram as que mostraram maior correlação com o processo inflamatório da cicatrização óssea. Estudos adicionais são necessários para determinar a sensibilidade das proteínas de fase aguda como previsores de complicações do tratamento das fraturas.

Análisis de los primeros 100 pacientes internados por COVID-19 en el Hospital de Clínicas José de San Martín, Universidad de Buenos Aires / Analysis of the first 100 patients with COVID-19 admitted to internal medicine wards at the Hospital de Clínicas José de San Martin, Buenos Aires University

Resumen Se analiza, en un estudio descriptivo retrospectivo, las características clínicas y epidemiológicas, la evolución de la enfermedad y su asociación con los marcadores del laboratorio de mal pronóstico, en los primeros 100 pacientes internados en clínica médica con COVID-19 en el Hospital de Clínicas José de San Martín de la Universidad de Buenos Aires. El 31% de los pacientes provenían de geriátricos, las manifestaciones clínicas más comunes fueron fiebre, tos y odinofagia. En relación a las comorbilidades, la obesidad fue la más frecuente y la hipertensión arterial la más prevalente en los pacientes con neumonía. La edad y la presencia de neumonía fueron los predictores más importantes de mortalidad. Los pacientes mayores de 70 años presentaron reactantes de fase aguda más elevados mostrando una respuesta inflamatoria exagerada. La mortalidad fue elevada (13%), en comparación con la mayoría de las comunicaciones (5%), probablemente como consecuencia de la edad avanzada de nuestra población y las condiciones clínicas desfavorables que presentaron a su ingreso.

Abstract This retrospective descriptive study analyzes the clinical and epidemiological characteristics, the disease evolution and its association with laboratory markers of poor prognosis of the first 100 patients with COVID-19 admitted to internal medicine wards at the Hospital de Clínicas José de San Martín, University of Buenos Aires. Thirty-one patients were nursing home residents, the most common clinical manifestations were fever, cough and odynophagia. Regarding comorbidities, obesity was the most frequent one and hypertension was the most prevalent in patients with pneumonia. The most important predictors of mortality were age and pneumonia. Patients older than 70 years had higher acute phase reactants showing an exaggerated inflammatory response. Mortality was high (13%), compared to most reports (5%), probably because of the advanced age of our population and the unfavorable clinical conditions they presented at admission.

Acute-phase protein concentration in bronchoalveolar lavage fluid from healthy horses / Proteínas de fase aguda do lavado broncoalveolar de equinos hígidos

Bronchoalveolar lavage fluid (BALF) was analyzed to obtain information on leakage of acute-phase proteins from the blood into the respiratory lumen and about local synthesis. Ceruloplasmin, transferrin, albumin, α1-antitripsin, immunoglobulin G heavy, immunoglobulin G light, immunoglobulin A, haptoglobin, acidic glycoprotein, and P23 were measured in BALF from 30 horses without inflammatory disease by sodium dodecyl sulfate polyacrylamide gel electrophoresis (SDS-PAGE). In serum, the same proteins were identified except for α1-antitrypsin. In conclusion, this study demonstrated that polyacrylamide gel electrophoresis (SDS-PAGE) can be used for the determination of acute-phase proteins in BALF samples from horses. In healthy horses, the values are very low, but they can be compared with reference values to assist in the diagnosis of animals with respiratory diseases.(AU)

O líquido obtido através da lavagem broncoalveolar (LBA) foi analisado para obter informações sobre as proteínas da fase aguda. Ceruloplasmina, transferrina, albumina, α1-antitripsina, imunoglobulina G pesada, imunoglobulina G leve, imunoglobulina A, haptoglobina, glicoproteína ácida e P23 foram medidas nos LBA de 30 cavalos sem doença inflamatória por eletroforese em gel de poliacrilamida com dodecilsulfato de sódio (SDS-PAGE). No soro, as mesmas proteínas foram identificadas, exceto a α1-antitripsina. Em conclusão, este estudo demonstra que a eletroforese em gel de poliacrilamida (SDS-PAGE) pode ser usada para a determinação de proteínas de fase aguda em amostras de LBA em cavalos. Em cavalos saudáveis, os valores são muito baixos, no entanto, podem ser comparados e auxiliar no diagnóstico de animais com doenças respiratórias.(AU)

ELISA of amyloid A in paired bronchoalveolar lavage fluid and serum samples of healthy horses / Detecção de amilóide A no lavado broncoalveolar de equinos hígidos

Pulmonary disorders are common in horses, and treatment efficiency depends on an adequate diagnosis. Amyloid A is the most sensitive indicator of pathology in horses. The objective of this study was to establish the concentration of amyloid A of bronchoalveolar lavage fluid (BALF) in healthy horses. Health condition of horses was considered normal based on physical examination, complete blood count, biochemical parameters, and BALF cytology. Blood and BALF were collected from thirty adult female horses. Amyloid A concentrations in serum and BALF were measured using commercial ELISA tests. Amyloid A was detected in serum (mean ± SD = 3.71±2.51) and BALF (mean ± SD = 0.000745±0.000785) of all horses. In conclusion, SAA can also be measured in bronchoalveolar fluid, affording early detection of respiratory infections or inflammatory conditions.(AU)

Resumen La neumonía en niños es causa frecuente de morbilidad y mortalidad, especialmente en países de bajos ingresos; es indispensable proporcionar una adecuada conducta terapéutica, idealmente orientada por etiología, pues la principal consecuencia de no establecer un diagnóstico etiológico preciso es el abuso de antibióticos. La evaluación clínica y radiológica son los pilares básicos para el diagnóstico de neumonía, y el conocimiento del comportamiento epidemiológico de los gérmenes y los biomarcadores ayudan a su aproximación etiológica. Se revisaron aspectos prácticos sobre el diagnóstico de la neumonía en niños, abordando criterios clínicos y epidemiológicos (edad y género), reactantes de fase aguda, hallazgos radiológicos y modelos de predicción etiológica utilizados como herramientas para la diferenciación de neumonía bacteriana de viral en menores de 18 años, en escenarios donde no se dispone rutinariamente de técnicas más precisas para diagnóstico rápido, como aquellas de tipo inmunológico o moleculares.

Abstract Pneumonia in children is a frequent cause of morbidity and mortality, especially in low-income countries. Due to this, it is indispensable to get a right therapeutic behavior, ideally focused by etiology, because the main consequence of not establishing an accurate etiological diagnosis is the abuse of antibiotics. The radiologic and clinic evaluations are basic pillars for pneumonia diagnosis and the knowledge in epidemiological behavior and biomarkers is very useful for an etiological approximation. Practical aspects were reviewed about pneumonia diagnosis in children, addressing clinic and epidemiological criteria (age and gender), acute phase reactants, radiological findings and etiological prediction models used as tools for differentiation between viral and bacterial pneumonia in children under 18 years old, in scenarios where it is not possible to find techniques for a right diagnostic, as those of immunologic and molecular types.

Analysis of hypothermia through the acute phase in major burns patients: Nursing care. / Análisis de la hipotermia durante la fase aguda del paciente gran quemado: cuidados enfermeros.

Major burns patients usually present hypothermia after suffering a thermal burn, due to exposure during the accident, cooling of the burn and transfer. There are methods of reheating to avoid this heat loss, where nursing care is key. OBJECTIVE: To analyse the constant temperature presented by large burns patients on admission to the Burns Unit and their progression over the first 72hours. METHOD: Retrospective cross-sectional descriptive observational study of patients with thermal burns affecting more than 15% of body surface area, from December 2010 to May 2018. By reviewing databases and clinical records, demographic data, qualitative variables (origin of burn, previous pathologies, mechanical ventilation and ABSI and BOBI scales) and quantitative variables (burn depth and extension, temperature at admission and taken every 8hours for 72hours). Absolute, relative frequencies and the statistics of the quantitative variables were analysed. The study was verified by statistical tests according to the variables and contingency tables. A logistic regression model was developed expressed in a ROC curve. RESULTS: Of the 57 patients included, 79.2% developed hypothermia on admission. They presented burns over 34.56%±16.64 of their body surface, with 28.04%±17.49 being deep burns. Mortality during the stay was 29.8%. The presence of hypothermia during the acute phase was statistically related to death during stay in the unit (p=.033). It was observed that hypothermia is directly related to the extent of the burn (p=.003). CONCLUSIONS: Due to the presence of hypothermia on admission, and to the fact that the average temperature does not exceed 36°C until at least 16hours after the burn, nurses must know and promptly administer adequate reheating measures to improve chances of survival in major burns.

Serum Levels of Alpha1-antitrypsin and Their Relationship With COPD in the General Spanish Population.

BACKGROUND: Low plasma level of alpha1-antitrypsin (AAT) is an established risk factor for early-onset chronic obstructive lung disease (COPD). However, less attention is given to the levels of AAT in the general population. METHODS: This is a part of a multicentre, population-based study conducted at 11 sites throughout Spain. Plasma levels of AAT were available for 837 persons with a mean (SD) age of 58.05 (11.3) years: 328-smokers, 272-ex-smokers and 237 non-smokers. Out of 837, 303 (36.2%) had a diagnosis of COPD, 222 (26.5%) had respiratory symptoms but no COPD, and 312 (37.3%) were healthy controls. RESULTS: In the whole cohort, the mean level of plasma AAT was 1.51 (0.47)g/L. Levels were higher in COPD patients [1.55 (0.45)g/L] and individuals with respiratory symptoms [1.57 (0.47)g/L] than in controls [1.43 (0.47)g/L], p<0.001, a finding which persisted after correction for age and CRP. Plasma AAT levels were negatively associated with FEV1/FVC ratio, after adjustment for age, sex, smoking status, CRP, TNFα, fibrinogen and albumin. The risk for COPD was significantly associated with higher AAT levels in univariate and multivariate models, with odds ratios of 1.8 and 1.5, respectively. In the univariate and multivariate models smoking status, gender, and CRP levels were also associated with COPD probability, demonstrating that they act independently. CONCLUSION: Increased circulating levels of AAT, similarly to CRP and other markers of systemic inflammation, is an important feature of COPD. Our results highlight a complex interrelationship between levels of AAT and health of respiratory system.

Development of an application for mobile phones (App) based on the collaboration between the Spanish Society of Rheumatology and Spanish Society of Family Medicine for the referral of systemic autoimmune diseases from primary care to rheumatology. / Desarrollo de una aplicación para teléfonos móviles (app) basada en la colaboración Sociedad Española de Reumatología/Sociedad Española de Medicina de Familia y Comunitaria para derivación de enfermedades autoinmunes sistémicas.

Management of systemic autoimmune diseases is challenging for physicians in their clinical practice. Although not common, they affect thousands of patients in Spain. The family doctor faces patients with symptoms and non-specific cutaneous, mucous, joint, vascular signs or abnormal laboratory findings at the start of the disease process and has to determine when to refer patients to the specialist. To aid in disease detection and better referral, the Spanish Society of Rheumatology and the Spanish Society of Family Medicine has created a group of experts who selected 26 symptoms, key signs and abnormal laboratory findings which were organized by organ and apparatus. Family doctors and rheumatologists with an interest in autoimmune systemic diseases were selected and formed mixed groups of two that then elaborated algorithms for diagnostic guidelines and referral. The algorithms were then reviewed, homogenized and adapted to the algorithm format and application for cell phone (apps) download. The result is the current Referral document of systemic autoimmune diseases for the family doctor in paper format and app (download). It contains easy-to-use algorithms using data from anamnesis, physical examination and laboratory results usually available to primary care, that help diagnose and refer patients to rheumatology or other specialties if needed.

Proteína C reactiva como indicador de engrosamiento de intima media carotídea en obesos / C reactive protein as indicator of intimate thickening carotid mean in obese

La obesidad constituye un esta- do subclínico de inflamación, que promueve complicaciones cardiovasculares. Objetivo: Establecer la relación entre la concentración de proteína C reactiva ultrasensible (PCRus) y el engrosamiento de la íntima media carotídea en obesos. Método: estudio transversal, descriptivo y comparativo. Se determinaron variables antropométricas, parámetros bioquímicos, concentración de PCRus, y gro- sor de íntima media carotídea (GIMC) en obesos normolipémicos y dislipidémicos. Resultados: se evaluaron 45 pacientes obesos normolipémicos y dislipidémicos, con una edad media de 36±9,23 años y 38,33±8,30 años respectivamente, sin diferencias significativas en peso, talla, circunferencia abdominal y presión arterial. La PCRus se encontró en 0,967±0,73mg/dl en el grupo normolipémi- co, y 1,328±0,75mg/dl, en el grupo dislipidémico, con significancia estadística (p=0,022) y una media de grosor de íntima media de 0,87±0,23mm y 0,95±0,20mm. Los pacientes con valores de PCRus ≥1mg/dl, presentaron un mayor peso, índice de masa corporal (IMC) y circunferencia abdo- minal. Se encontró una correlación de 0,361 entre el GIMC y PCRus, y en el grupo normolipémico, una correlación de 0,423 (p=0,004). Igualmente, se encontró una correlación de 0,336 entre el GIMC y la circunferencia abdominal en los normolipémicos. Conclusión: La PCRus ≥1mg/dl en pacientes obesos, se correlacionó con un mayor peso, el IMC y la circunferencia abdominal, así como aumento del GIMC y presencia de placas de ateroma. En pacientes obesos normolipémicos, se encontró correlación moderada entre el grosor de íntima media carotídea, con la PCRus y circunfe- rencia abdominal(AU)

Obesity is a condition of subclini- cal inflammation, which promotes cardiovascular complications. Objective: To establish the rela- tionship between the concentration of high sensitive C reactive protein (CPRhs) and carotid media- intima thickness in obese normolipidemic patients. Methods: crosssectional, descriptive and comparative study. Anthropometric variables, biochemi- cal parameters, CPRhs concentration, and carotid media-intima thickness (IMT) were determined in normolypemic and dyslipidemic obese patients. Results: 45 normolipidemic and dyslipidemic patients were evaluated, with an average age of 36±9,23 years and 38,33±8,30 years respectively, without significant differences in weight, height, abdominal circumference and blood pressure. The CPRhs was found in 0,967±0,73mg/dl in the normolipidemic group, and 1,328±0,75mg/dl in the dyslipidemic group, with statistical significance (p=0.022) and an average IMT of 0,87±0,23mm and 0,95±0,20mm respectively. Patients with CPRhs ≥1mg/dl values had higher weight, body mass index (BMI) and abdominal circumference. A correlation of 0,361 was found between the IMT and CPRhs, and in the normolipidemic group, a correlation of 0,423 (p=0.004). The correlation of 0,336 was found between IMT and abdominal circumference in normolipidemic patients. Conclusion: CPRhs ≥1mg/dl in obese patients, was correlated with increased weight, BMI and abdominal circumference, as well as increased IMT and presence of atherosclerosis plaques. In obese normolipidemic patients, a moderate correlation was found between carotid media-intima thickness with IMT and abdo- minal circumference, may suggest the use of these markers in primary atherosclerotic disease preven- tion in obese patients(AU)

Relación entre niveles de proteína c-reactiva y Síndrome de Burnout en médicos de postgrado / Relationship between c-reactive proteins and burnout syndrome in postgraduate physicians / Relação entre os níveis de proteína c-reativa e a síndrome de burnout nos médicos pós-graduação

Introducción. El Síndrome de Burnout afecta mundialmente a más de 100,000,000 personas, con prevalencia entre 47 y 76% en médicos residentes. El objetivo de este trabajo fue determinar la relación entre el Síndrome de Burnout y los niveles de proteína C-reactiva ultrasensible en médicos residentes de un hospital universitario en Caracas, Venezuela. Metodología. Estudio transversal y descriptivo. El instrumento de recolección de datos, así como el test Maslach Burnout Inventory, fueron enviados en formato electrónico. Posteriormente, se seleccionó dos submuestras, a quienes se les determinó la concentración de proteína C-reactiva ultrasensible Resultados. La muestra inicial fue de 174 residentes, de los cuales 57 (32.8%) presentaban Burnout. Los residentes positivos para la presencia del síndrome tenían niveles más elevados de proteína C-reactiva ultrasensible (>0.50mg/dl) (р=0.001) con respecto al grupo sin Burnout. Igualmente, los residentes de género femenino (р=0.046), aquellos que dormían menos de 8 horas al día (р=0.032) y que estaban sometidos a estrés familiar (р=0.036) presentaron una asociación estadísticamente significativa para desarrollar el síndrome de bornout. Finalmente, se evidenció cómo los residentes de menor edad tenían mayores puntajes en la subescala despersonalización (p=0.036). Discusión. El estrés crónico (entre ellos el Síndrome de Bornout) puede activar de manera continua ejes fisiológicos estresores (hipotálamo-hipófisis- suprarrenal y simpático-adrenal); conllevando a la producción de citosinas y proteínas de fase aguda (como proteína C-reactiva ultrasensible), promoviendo un estado proinflamatorio en el individuo y el desarrollo de patologías crónicas. Conclusiones. El síndrome de bornout y las variables sociodemográficas/laborales representan una condición de estrés crónico que pueden asociarse entre sí y conducir al desarrollo de distintas enfermedades a largo plazo.

Introduction. Burnout Syndrome affects over 100,000,000 people worldwide, with a prevalence of between 47% and 76% in resident physicians. This project's objective is to determine the relationship between Burnout Syndrome and ultrasensitive C-reactive protein in resident physicians in a university hospital in Caracas, Venezuela. Methodology. Cross-sectional and descriptive study. The data collection tool, as well as Maslach Burnout Inventory test, were sent digitally. Two sub-samples were subsequently collected, whose concentration of us ultrasensitive C-reactive protein was determined. Results. The initial sample was 174 residents, of which 57 (32.8%) had Burnout. Residents who tested positive for the syndrome had higher levels of us-CRP (>0.50mg/dl) (р=0.001) with respect to the group without Burnout. Moreover, female residents (р=0.046), those who slept less than 8 hours every day (р=0.032) and those who were subject to family stress (р=0.036) demonstrated a statistically significant association with developing Burnout Syndrome. Finally, it was evident how younger residents had higher scores on the Depersonalization Subscale (p=0.036). Discussion. Chronic stress (among which is burnout syndrome) can continuously activate physiological stress axes (hypothalamic-pituitary-suprarenal and sympathetic-adrenal), which leads to producing cytosines and acute-phase proteins (such as ultrasensitive C-reactive protein), promoting a proinflammatory state in individuals and the development of chronic pathologies. Conclusion. Burnout Syndrome and sociodemographic/work variables represent a chronic stress condition and can be related to each other. They may lead to developing various long-term diseases.

Introdução. A Síndrome de Burnout afeta mais de 100 milhões de pessoas em todo o mundo, com uma prevalência de 47-76% em médicos residentes. O objetivo deste trabalho foi determinar a relação entre a síndrome de burnout e os níveis de proteína C-reativa ultrassensível em médicos residentes de um hospital universitário em Caracas, Venezuela. Metodologia. Trata-se de um estudo transversal e descritivo. O instrumento de coleta de dados, assim como o teste Maslach Burnout Inventory, foram enviados em formato eletrônico. Posteriormente, foram selecionadas duas subamostras, nas quais foi determinada a concentração de níveis de proteína C-reativa. Resultados. A amostra inicial foi de 174 residentes, dos quais 57 (32.8%) apresentaram Burnout. Os residentes positivos para a presença da síndrome apresentaram níveis mais elevados de níveis de proteína C-reativa (> 0.50mg/dl) (р = 0.001) em comparação com o grupo sem Burnout. Da mesma forma, residentes do sexo feminino (р = 0.046), aqueles que dormiam menos de 8 horas por dia (р = 0.032) e aqueles que foram submetidos a estresse familiar (р = 0.036) apresentaram uma associação estatisticamente significativa para o desenvolvimento da síndrome de burnou. Por fim, evidenciou-se que os residentes mais jovens apresentaram escores mais elevados na subescala de despersonalização (p = 0.036). Discussão. O estresse crônico (incluindo a síndrome de burnout) pode ativar continuamente os eixos fisiológicos dos estressores (hipotálamo-hipófise-suprarrenal e simpático-adrenal), levando à produção de citocinas e proteínas de fase aguda (como níveis de proteína C-reativa), promovendo um estado pró-inflamatório no indivíduo e o desenvolvimento de patologias crônicas. Conclusão. A síndrome de burnout e as variáveis sociodemográficas/laborais representam uma condição de estresse crônico que podem estar associadas entre si e levar ao desenvolvimento de diferentes doenças a longo prazo.
