Usefulness of thoracic ultrasound in the assessment of removal of indwelling pleural catheter in patients with malignant pleural effusion.

INTRODUCTION: There are no defined criteria for deciding to remove a non-functioning indwelling pleural catheter (IPC) when lung re-expansion on chest X-ray is incomplete. Chest computed tomography (chest CT) is usually used. The objective of this work is to validate the usefulness of chest ultrasound performed by a pulmonologist and by a radiologist compared to chest CT. PATIENTS AND METHODS: Prospective, descriptive, multidisciplinary and multicenter study including patients with malignant pleural effusion and non-functioning IPC without lung reexpansion. Decisions made on the basis of chest ultrasound performed by a pulmonologist, and performed by a radiologist, were compared with chest CT as the gold standard. RESULTS: 18 patients were analyzed, all of them underwent ultrasound by a pulmonologist and chest CT and in 11 of them also ultrasound by a radiologist. The ultrasound performed by the pulmonologist presents a sensitivity of 60%, specificity of 100%, PPV 100% and NPV 66% in the decision of the correct removal of the IPC. The concordance of both ultrasounds (pulmonologist and radiologist) was 100%, with a kappa index of 1. The 4 discordant cases were those in which the IPC was not located on the ultrasound. CONCLUSIONS: Thoracic ultrasound performed by an expert pulmonologist is a valid and simple tool to determine spontaneous pleurodesis and remove a non-functioning IPC, which would make it possible to avoid chest CT in those cases in which lung reexpansion is observed with ultrasonography.

Diagnostic performance of a clinical ultrasound-based algorithm for acute heart failure in patients presenting to the emergency department with dyspnea. / Rendimiento diagnóstico de un algoritmo basado en ecografía clínica para el diagnóstico de insuficiencia cardiaca aguda en pacientes que consultan en urgencias por disnea.

OBJECTIVES: To study the diagnostic performance of an ultrasound-based algorithm that includes the deceleration time (DT) of early mitral filling to establish a diagnosis of acute heart failure (AHF) in patients who come to an emergency department because of dyspnea. MATERIAL AND METHODS: Prospective analysis in a convenience sample of patients who came to a hospital emergency department with acute dyspnea. The algorithm included ultrasound findings and 4 echocardiographic findings as follows: mitral annular plane systolic excursion, Doppler mitral flow velocity, tissue Doppler imaging measure of the lateral annulus, and the DT of early mitral filling. The definitive diagnosis was made by 2 physicians blinded to each other's diagnosis and the ultrasound findings. RESULTS: A total of 166 adult patients with a mean (SD) age of 76 (13) years were included; 79 (48%) were women. AHF was the definitive diagnosis in 62 patients (37%). Diagnostic agreement was good between the 2 physicians (κ = 0.71). The algorithm classified all the patients, and there were no undetermined diagnoses. Diagnostic performance indicators for the ultrasound-based algorithm integrating early DT findings were as follows: area under the receiver operating characteristic curve, 0.91 (95% CI, 0.86-0.96); sensitivity, 87% (95% CI, 76%-94%); specificity, 95% (95% CI, 89%-98%); positive likelihood ratio, 18.1 (95% CI, 7.7-42.8); and negative likelihood ratio, 0.14 (95% CI, 0.07-0.26). CONCLUSION: The ultrasound-based algorithm integrating the DT of early mitral filling performs well for diagnosing AHF in emergency patients with dyspnea. The inclusion of early DT allows all patients to be diagnosed.

METODO: Análisis prospectivo de una muestra de conveniencia de pacientes que consultan por disnea aguda en un SUH. El algoritmo ecográfico incluyó la ecografía pulmonar y cuatro parámetros ecocardiográficos, se midió MAPSE (desplazamiento sistólico del plano del anillo mitral), medidas doppler de flujo mitral, medidas doppler tisular en el anillo mitral lateral y TD. El diagnóstico final fue asignado por 2 médicos ciegos entre sí y a los hallazgos ecográficos. RESULTADOS: Se incluyeron 166 pacientes adultos, la edad media fue de 76 años (DE 13) y 79 eran mujeres (48%). Hubo 62 pacientes (37%) con un diagnóstico final de ICA. La concordancia entre asignadores fue buena para el diagnóstico de ICA (κ = 0,71). El algoritmo clasificó a todos los pacientes, no hubo ningún diagnóstico indeterminado. El rendimiento diagnóstico del algoritmo mostró un área bajo la curva de 0,91 (IC 95%: 0,86-0,96), sensibilidad del 87% (IC 95%: 76%-94%), especificidad del 95% (IC 95%: 89%-98%), razón de verosimilitud positiva del 18,1 (IC 95%: 7,7-42,8), razón de verosimilitud negativa del 0,14 (IC 95%: 0,07-0,26). CONCLUSIONES: Un algoritmo ecográfico que incluye el TD tiene un buen rendimiento para el diagnóstico de ICA en pacientes que acuden a SUH por disnea. Además, el uso de TD permite clasificar a todos los pacientes.

Precision medicine: "Point of Care Ultrasound" (PoCUS) in the diagnostic approach to the patient with hyponatremia.

Hyponatremia is a multifactorial disorder defined as a decrease in plasma sodium concentration. Its differential diagnosis requires an adequate evaluation of the extracellular volume (ECV). However, ECV determination, simply based on the clinical history, vital signs, physical examination, and laboratory findings can leads to misdiagnosis and inappropriate treatment. The use of Point-of-Care Ultrasound (POCUS), through the combination of Lung Ultrasound (LUS), Venous Excess UltraSound (VExUS) and Focused Cardiac Ultrasound (FoCUS), allows a much more accurate holistic assessment of the patient's ECV status in combination with the other parameters.

Cost-effectiveness analysis of the diagnosis of temporal arteritis.

Temporal arteritis (TA) is the most common form of systemic vasculitis. Its diagnosis is based on criteria proposed by the American College of Rheumatology (1990), and its treatment is high-dose corticosteroids. Our objective is to assess the cost of diagnosing TA, and secondarily, cost-effective analysis of different diagnostic strategies (clinical, biopsy, doppler ultrasound) and therapeutic strategies (corticosteroid suspension). MATERIAL AND METHOD: Observational, retrospective study has been carried out on patients with AT (2012-2021). Demographic data, comorbidities, signs and symptoms suggestive of AT were collected. AT was diagnosed with a score ≥ 3 according to American College of Rheumatoloy criteria (ACR-SCORE). The costs of diagnosis and treatment modification were analysed. RESULTS: Seventy-five patients have been included, median age 77 (46-87) years. Headache, temporal pain and jaw claudication were significant for the diagnosis of TA. Patients with a halo on Doppler ultrasound and a positive biopsy have significantly elevated ESR and CRP compared to patients who do not. The cost of the AT diagnosis was 414.7 euros/patient. If we use ACR-SCORE ≥ 3-echodoppler it is 167.2 є/patient (savings 59.6%) and ACR-SCORE ≥ 3-biopsy 339.75 є/patient (savings 18%). If the corticosteroid was removed and a biopsy was performed, 21.6 є/patient (94.7% savings), if the corticosteroid was removed and Doppler ultrasound was performed, 10.6 є/patient (97.4% savings). CONCLUSIONS: Headache, temporary pain and jaw claudication are predictors of AT. Elevated ESR and CRP are predictors of positive biopsy and presence of halo on ultrasound. The uses of ACR-SCORE ≥ 3 with Doppler ultrasound or biopsy, and with corticosteroid suspension, are cost-effective.

Detection of subclinical atherosclerosis using vascular ultrasound as a vascular risk assessment method. Simplified protocol. / Detección de aterosclerosis subclínica mediante ecografía vascular como método de evaluación de riesgo vascular. Protocolo simplificado.

Cardiovascular disease secondary to atherosclerosis is the main cause of morbidity and mortality in the world. Cardiovascular risk stratification has proven to be an insufficient approach to detect those subjects who are going to suffer a cardiovascular event, which is why for years other markers have been sought to help stratify each individual with greater precision. Two-dimensional vascular ultrasound is a excellent method for vascular risk assessment.

Análisis coste/efectivo del diagnóstico de la arteritis de la temporal / Cost-effectiveness analysis of the diagnosis of temporal arteritis

La arteritis de la temporal (AT) es la forma más frecuente de vasculitis sistémica, su diagnóstico está basado en criterios propuestos por el Colegio Americano de Reumatología (1990), y su tratamiento son corticoides a dosis elevadas. Nuestro objetivo es valorar el gasto del diagnóstico de la AT, y secundariamente análisis coste/efectivo de distintas estrategias diagnósticas (clínica, biopsia, eco-Doppler) y terapéuticas (suspensión del corticoide). Material y método: Estudio observacional, retrospectivo de pacientes con AT (2012-2021). Se recogieron datos demográficos, comorbilidades, signos y síntomas sugestivos de AT. Se diagnosticó AT con una puntuación ≥3 según los criterios del American College of Reumatology (ACR-SCORE). Se analizaron los gastos del diagnóstico y modificación de tratamiento. Resultados: Setenta y cinco pacientes, mediana edad 77 (6-87) años. Cefalea, dolor temporal y claudicación mandibular fueron significativos para el diagnóstico de AT. Los pacientes con halo en eco-Doppler y biopsia positiva, presentaron elevación de VSG y PCR de forma significativa en comparación con los pacientes que no. El gasto diagnóstico de AT fue de 414,7€/paciente. Si empleamos ACR-SCORE≥3-eco-Doppler serían 167,2€/paciente (ahorro del 59,6%) y ACR-SCORE≥3-biopsia 339,75€/paciente (ahorro del 18%). Si se retiraba corticoide y se realizaba biopsia hubiesen sido 21,6€/paciente (ahorro del 94,7%), si se retiraba corticoide y se realizaba eco-Doppler hubiesen sido 10,6€/paciente (ahorro del 97,4%). Conclusiones: Cefalea, dolor temporal y claudicación mandibular son predictores de AT. La elevación de VSG y PCR son predictores de biopsia positiva y presencia de halo en la ecografía.El empleo de ACR-SCORE≥3 con eco-Doppler o con biopsia, y con suspensión del corticoide son coste/efectivos.(AU)

Medicina de precisión: «Point of Care Ultrasound» (PoCUS) en el abordaje diagnóstico del paciente con hiponatremia / Precision medicine: “Point of Care Ultrasound” (PoCUS) in the diagnostic approach to the patient with hyponatremia

La hiponatremia es un trastorno multifactorial definido como una disminución en la concentración plasmática de sodio. Su diagnóstico diferencial requiere una evaluación adecuada del volumen extracelular. Sin embargo, la determinación del volumen extracelular, simplemente basada en la historia clínica, las constantes vitales, el examen físico y los hallazgos de laboratorio, conducen en ocasiones a un diagnóstico erróneo por lo que el enfoque terapéutico puede ser equivocado. El empleo de ecografía a pie de cama (Point-of-Care Ultrasound [PoCUS]), mediante la combinación de ecografía pulmonar (Lung Ultrasound [LUS]), Venous Excess UltraSound (VExUS) y la ecocardioscopia (Focused Cardiac Ultrasound [FoCUS]) permiten, en combinación con el resto de los parámetros, una valoración holística mucho más precisa del estado del volumen extracelular del paciente.(AU)

[Use of clinical ultrasound in primary care: Multicenter prospective study]. / Uso de la ecografía clínica en Atención Primaria. Estudio prospectivo multicéntrico.

OBJECTIVE: The objective was to describe the characteristics of the use of clinical ultrasound in two health centers (SC) of Health Area VII of the Region of Murcia (CS Murcia-Sur and CS Floridablanca). DESIGN: Observational, descriptive, longitudinal, prospective and multicenter study. SITE: CS Murcia-Sur and CS Floridablanca (Health Area VII of the Region of Murcia). PARTICIPANTS: One hundred and thirty-five patients were included. INTERVENTIONS: Performance of clinical ultrasound in the primary care (PC) consultation. MAIN MEASUREMENTS: Demographic variables (age, sex), as well as clinical variables (reason for consultation, type of ultrasound, results, referrals to the second hospital level, degree of diagnostic agreement) were collected. RESULTS: One hundred and thirty-five patients were included, more than 50% were female. The main reason for consultation was musculoskeletal and soft tissue symptoms (44.4%), followed by digestive symptoms (21.5%). 44.4% of the ultrasounds were classified as normal, while pathological findings were found in 55.6%. Confirmatory tests were requested in 43.7% and the findings were confirmed in 67% of the patients. CONCLUSIONS: The use of ultrasound in PC allows to show the high prevalence of pathological findings in the examination of patients. In a technique that helps the clinician in his diagnostic-therapeutic process. The integration of clinical ultrasound in the PC consultation can save complementary studies and referrals to a second level of care. Its implementation in PC requires proper training of professionals.

Usefulness of ultrasound in clinical decision-making in rheumatology clinical practice: A single-center longitudinal study.

OBJECTIVE: The purpose of the present study is to identify the extent to which it affects clinical decisions in a single-centre observational retrospective study. METHOD: The results of 801 requests and 1174 consecutive individual ultrasound examinations performed over 10 months were analysed. RESULTS: The most frequent indication was diagnostic assistance (39%) followed by assessment of inflammatory activity (34%). By topography, the hand was the most frequently studied region (51%), followed by the foot (18.1%). Of all requests, 67% had an impact on decision-making. The impact on clinical decision-making was associated with a shorter waiting time for the evaluation of the results, being the greatest in those ultrasound scans performed on demand on the same day of the request. In 73% of bilateral ultrasound studies, findings in one of the joints exemplified the overall result reported. CONCLUSIONS: Rheumatological musculoskeletal ultrasound has proven to be a useful decision-making technique, the greater the impact of which is seen the shorter the waiting time before it is performed.

Cardiovascular event in a cohort of rheumatoid arthritis patients in Castilla-La Mancha: Utility of carotid ultrasound.

Rheumatoid Arthritis (RA) has a mortality rate 1,3 to 3 times higher than the general population, with cardiovascular mortality accounting for 40-50% of cases. Currently, cardiovascular disease is considered an extraarticular manifestation of RA (OR: 1,5-4,0). Ultrasound measurement of the intima-media thickness (IMT) of the common carotid artery and the presence of atherosclerotic plaques (AP) is a non-invasive method and a surrogate marker of subclinical arteriosclerosis. OBJECTIVE: To determine if subclinical arteriosclerosis findings through carotid ultrasound can serve as a good predictor of cardiovascular events (CVE) development in a cohort of RA patients over a 10-year period. METHODOLOGY: A cohort of RA patients seen in the Rheumatology outpatient clinic of a hospital in Castilla La Mancha in 2013 was evaluated. A prospective evaluation for the development of CVE over the following 10 years was conducted, and its correlation with previous ultrasound findings of IMT and AP was analyzed. RESULTS: Eight (24%) patients experienced a CVE. Three (9%) had heart failure, three (9%) had a stroke, and two (6%) experienced acute myocardial infarction. RA patients who developed a CVE had a higher IMT (0,97 +/- 0.08 mm) compared to the RA patients without CV complications (0,74 +/- 0.15 mm) (p = 0,003). The presence of IMT ≥ 0.9 mm and AP had a relative risk of 12,25 (p = 0,012) and 18,66 (p = 0,003), respectively, for the development of a CVE. CONCLUSIONS: Carotid ultrasound in RA patients may allow for early detection of subclinical atherosclerosis before the development of CVE, with IMT ≥ 0.9 mm being the most closely associated finding with CVE, unaffected by age.

Tratamiento de la pseudoartrosis de radio con injerto de cresta iliaca y células madre del aspirado de médula ósea. A propósito de un caso / Treatment of radial pseudarthrosis with iliac crest graft and bone marrow aspirate stem cells. A case report

La pseudoartrosis es una complicación caracterizada por la ausencia de consolidación del hueso a los 9 meses desde el inicio de la fractura, con falta de progresión radiológica los últimos 3 meses, siendo sus principales causas el exceso de movimiento en el foco de fractura y una insuficiente vascularización. A pesar de no tratarse de una complicación frecuente, los huesos del antebrazo ocupan el 4.º puesto en incidencia de presentación. El manejo anestésico de la patología quirúrgica del miembro superior se realiza generalmente en régimen ambulatorio con técnicas de anestesia regional guiadas por ecografía. Estas técnicas tienen una doble función: anestesia durante el propio acto quirúrgico con una mínima variabilidad sobre el estado basal del paciente y analgesia en el postoperatorio inmediato, permitiendo de esta manera el alta a domicilio de forma más segura y precoz. Presentamos el caso de un varón de 34 años, con desarrollo de pseudoartrosis atrófica tras fractura diafisaria de radio, en el que se realiza injerto óseo de cresta ilíaca y aspirado de células madre como estímulo de la osteogénesis.(AU)

Pseudarthrosis is a complication characterised by the absence of bone healing 9 months after the onset of the fracture, with a lack of radiological progressionin the last 3 months, and its main causes are excessive movement at the fracture site and insufficient vascularisation. Despite not being a frequent complica-tion, the bones of the forearm occupy the fourth place in incidence of presentation. The anaesthetic management of surgical pathology of the upper limb isgenerally performed on an outpatient basis with regional anaesthesia techniques guided by ultrasound. These techniques have a dual function: anaesthesiaduring the surgical act with minimal variability over the patient’s baseline condition and analgesia in the immediate postoperative period, thus allowing forsafer and earlier discharge home. We present the case of a 34-year-old male with diagnosis of atrophic pseudarthrosis following a diaphyseal fracture of theradius, in whom iliac crest bone grafting and stem cell aspiration were performed to stimulate osteogenesis.(AU)

Utilidad de la ecografía reumatológica en la toma de decisiones en la práctica clínica: Estudio unicéntrico longitudinal / Usefulness of ultrasound in clinical decision-making in rheumatology clinical practice: A single-center longitudinal study

Objetivo: El propósito del presente estudio es identificar en qué medida la ecografía reumatológica afecta a las decisiones clínicas mediante un estudio unicéntrico observacional retrospectivo. Método: Se analizaron los resultados de 801 solicitudes y 1174 ecografías individuales consecutivas realizadas a lo largo de 10 meses. Resultados: La indicación más frecuente fue la asistencia diagnóstica (39%) seguida de la evaluación de actividad inflamatoria (34%). Por topografía, la mano fue la región más estudiada (51%), seguida del pie (18,1%). De todas las solicitudes, en el 67% se constató un impacto en la toma de decisiones. El impacto en la decisión clínica se asoció a un menor tiempo de espera hasta la evaluación de los resultados, siendo el mayor en aquellas ecografías realizadas a demanda el mismo día de su petición. En el 73% de los estudios ecográficos bilaterales, los hallazgos en una de las articulaciones ejemplificaban el resultado global emitido. Conclusiones: La ecografía reumatológica demuestra ser una técnica útil en la toma de decisiones, cuyo mayor impacto se constata cuanto menor es el tiempo de espera hasta la evaluación de los resultados.(AU)

Evento cardiovascular en una cohorte de pacientes con artritis reumatoide en Castilla-La Mancha, utilidad de la ecografía carotídea / Cardiovascular event in a cohort of rheumatoid arthritis patients in Castilla-La Mancha: Utility of carotid ultrasound

La artritis reumatoide (AR) presenta una mortalidad de 1,3-3 veces superior a la población general donde destaca la mortalidad de origen cardiovascular con un 40-50%. Actualmente se considera la enfermedad cardiovascular como una manifestación extraarticular de la AR, siendo un factor de riesgo independiente de los tradicionales, con un riesgo elevado de enfermedad cardiovascular (OR: 1,5-4,0). La medición ecográfica del grosor íntimo medial (GIM) de la arteria carótida común y la presencia de placas ateromatosas es un método no invasivo y marcador subrogado de arterioesclerosis subclínica. Objetivo: Establecer si los hallazgos de arterioesclerosis subclínica por ecografía carotídea pueden ser un buen predictor del desarrollo de eventos cardiovasculares (ECV) en una cohorte de pacientes con AR a 10 años. Metodología: Se evaluó una cohorte de pacientes con AR atendidos en consulta externa de Reumatología de una hospital de Castilla-La Mancha durante el año 2013. Se realizó una evaluación para el desarrollo de ECV a los 10 años siguientes de comenzado el estudio y se analizó su correlación con los hallazgos ecográficos previos de GIM y placas ateromatosas. Resultados: Ocho (24%) pacientes presentaron un ECV. Tres (9%), episodio de fallo cardiaco; 3 (9%) accidente cerebrovascular y 2 (6%) episodio de infarto agudo al miocardio. Los pacientes con AR que desarrollaron un ECV habían presentado un GIM mayor (0,97±0,08mm) en comparación con los pacientes con AR que no tuvieron complicaciones cardiovasculares (0,74±0,15mm) (p=0,003). La presencia de un GIM≥0,9mm y placas ateromatosas representó un riesgo relativo de 12,25 (p=0,012) y 18,66 (p=0,003), respectivamente, para el desarrollo de un ECV. Conclusiones: La ecografía carotídea en pacientes con AR nos podría permitir la detección precoz de aterosclerosis subclínica antes del desarrollo de ECV, siendo fundamentalmente el GIM≥0,9mm el hallazgo más asociado a ECV y no influenciado por la edad.(AU)

The presence of IMT≥0.9mm and atherosclerotic plaques had a relative risk of 12.25 (P=.012) and 18.66 (P=.003), respectively, for the development of a CVE. Conclusions: Carotid ultrasound in RA patients may allow for early detection of subclinical atherosclerosis before the development of CVE, with IMT≥0.9mm being the most closely associated finding with CVE, unaffected by age.(AU)

Empleo de un score semicuantitativo en la valoración de la congestión pulmonar: prevalencia e implicaciones en el manejo diurético tras el alta por insuficiencia cardiaca / Semi-quantitative pulmonary congestion score: prevalence and diuretic management implications after heart failure discharge

Introducción La congestión persistente tras el alta por insuficiencia cardiaca (IC) se asocia a mayor riesgo de reingresos, siendo necesaria su valoración de forma precisa. Material y métodos Un total de 82 pacientes incluidos tras el alta por IC con el objetivo de caracterizar de forma sencilla y semicuantitativa el grado de congestión pulmonar y sus cambios, describiendo la relación entre dichos hallazgos y el manejo diurético. Resultados En la visita postalta, pese a la ausencia de congestión clínica en la mayoría de pacientes, la mitad presentaba algún grado de congestión pulmonar por ecografía. Tras valoración ecográfica y clínica en esta visita inicial se bajó el diurético en 50 pacientes (60%), se mantuvo igual en 16 (20%) y se aumentó en el resto. En los 45 pacientes sin congestión ecográfica, la bajada de diuréticos se intentó en el 80% siendo exitosa esta estrategia en la mayoría de ellos. Conclusiones La ecografía pulmonar, usando métodos de cuantificación sencillos, permite su incorporación real a nuestra práctica clínica ayudándonos en la toma de decisiones. (AU)

Introduction Persistent congestion after heart failure (HF) discharge is associated with a higher risk of readmissions. Material and methods Eighty-two patients included after HF discharge. The aim of the study was to characterize semiquantitatively the degree of pulmonary congestion and its changes, describing the relationship between these findings and diuretic management. Results On the first visit, despite the absence of clinical congestion in the majority of patients, half of the had some degree of pulmonary congestion by ultrasound. After global assessment in this initial visit (clinical and ultrasound) the diuretic was lowered in 50 patients (60%), kept the same in 16 (20%) and it was increased in the rest. In the 45 patients without ultrasound congestion, diuretic reduction was attempted in 80%, being this strategy successful in the majority of them. Conclusions Lung ultrasound, using simple quantification methods, allows its real incorporation into clinical practice, helping us in the decision making process. (AU)

Ultrasound-guided puncture vs conventional technique for arterial blood gas analysis sampling in adults: A systematic review.

AIM: To compare the efficacy of conventional puncture versus ultrasound-guided puncture for arterial blood gas sampling in adults. METHOD: A search protocol was developed and applied to three databases (Medline, Cochrane, and Dialnet). Clinical trials published between January 2013 and January 2023, in Spanish or English, were considered. Outcomes in terms of first-attempt success, number of attempts until success, time taken, self-reported iatrogenic pain, and patient or professional experience were collected. The risk of bias for each included study was assessed. RESULTS: Five randomized clinical trials were selected, with sample sizes ranging from 50 to 238 adult patients treated in emergency settings. Three out of four studies showed higher first-attempt success rates when using ultrasound, and 2 out of 4 studies reported a decrease in iatrogenic pain. Discrepant findings were observed among the studies in terms of time taken and the number of attempts required for success. CONCLUSIONS: Although current evidence is limited and the findings are heterogeneous, ultrasound-guided arterial puncture may have advantages over conventional puncture in terms of first-attempt success and in reducing iatrogenic pain.

Nuevo índice aterogénico para la predicción de aterosclerosis carotídea basado en la ratio proteína C reactiva no ultrasensible/HDL / New atherogenic index for the prediction of carotid atherosclerosis based on the non-ultrasensitive c-reactive protein/HDL ratio

Introducción La valoración del riesgo cardiovascular aparece en las guías clínicas como medida de prevención de enfermedades cardiovasculares, cuya etiología fundamental es la arteriosclerosis. Una de las herramientas que se utiliza para estimar el riesgo en práctica clínica son los índices aterogénicos (IA), cocientes entre fracciones lipídicas con rangos de referencia bien establecidos. A pesar de su uso extendido, existe todavía información limitada sobre su utilidad clínica. En los últimos años, algunas investigaciones han reforzado el papel de la inflamación en la etiología y cronicidad del proceso aterosclerótico. La inclusión de parámetros inflamatorios en el cálculo de IA podría mejorar su rendimiento diagnóstico en la detección de arteriosclerosis. Nos propusimos evaluar un nuevo IA en forma de ratio entre los valores de proteína C reactiva (PCR) no ultrasensible y las cifras de colesterol unido a lipoproteínas de alta densidad (HDL). Métodos Se incluyeron en el estudio 282 pacientes, asintomáticos, y sin historia de enfermedad cardiovascular. Se realizó en todos ellos analítica con perfil lipídico y PCR, y en el plazo inferior a un mes, ecografía carotídea para evaluar la presencia de ateromatosis. El nuevo IA se estableció como el cociente entre el valor de PCR no ultrasensible en mg/dL (multiplicado por 100) y el valor de HDL en mg/dL. Se comparó con los índices de Castelli I y II, y el índice aterogénico del plasma. La curva ROC determinó que el punto de corte óptimo del nuevo IA fue valor=1, con un área bajo la curva de 0,678 (IC 95% 0,60-0,75; p<0,001). ResultadosLa edad media de la muestra fue 60,4±14,5 años. Un total de 118 pacientes (41,8% del total) tenían arteriosclerosis carotídea. Al evaluar el rendimiento diagnóstico de los IA, encontramos que la ratio PCR·100/HDL mostró los valores más elevados de sensibilidad y valor predictivo positivo (0,73 y 0,68, respectivamente) ...

Introduction Current guidelines recommend cardiovascular risk assessment as a preventive measure for cardiovascular diseases, whose fundamental etiology is arteriosclerosis. One of the tools used to estimate risk in clinical practice are atherogenic indices (AI), ratios between lipid fractions with well-established reference ranges. Despite its widespread use, there is still limited information on its clinical utility. In recent years, some research has reinforced the role of inflammation in the etiology and chronicity of the atherosclerotic process. The inclusion of inflammatory parameters in the AI calculation could improve its diagnostic performance in the detection of arteriosclerosis. We sought to evaluate a new AI as a ratio between C-reactive protein (CRP) values and high-density lipoprotein cholesterol (HDL) values. Methods A total of 282 asymptomatic patients with no history of cardiovascular disease were included in the study. Laboratory tests with lipid profile and CRP, and carotid ultrasound to assess the presence of atheromatosis were performed in all of them. The new AI is established as the ratio between non-ultrasensitive CRP value in mg/dL (multiplied by 100) and HDL value in mg/dL. It was compared with the Castelli I and II indices, and the plasma atherogenic index. The optimal cut-off point of the new AI was value=1 as determined by ROC curve, with an area under the curve of 0.678 (95% CI 0.60-0.75; p<0.001).Results Mean age of patients was 60.4±14.5 years. A total of 118 patients (41.8% of total) had carotid arteriosclerosis. When evaluating the diagnostic performance of different AIs, we found that CRP·100/HDL ratio showed the highest values of sensitivity and positive predictive value (0.73 and 0.68, respectively) compared to the Castelli I and II indices, and the plasma atherogenic index. ...

Ecografía en el postoperatorio de cirugía cardíaca / Ultrasound use after cardiac surgery

La complejidad de los procedimientos quirúrgicos, así como la comorbilidad de los pacientes sometidos a cirugía cardiaca, van en aumento. La detección y el tratamiento precoz de las complicaciones posquirúrgicas son parte del éxito en la reducción de la morbimortalidad. La introducción de la técnica ecográfica ha sido fundamental en la valoración cardiopulmonar, hemodinámica y etiológica del paciente crítico, aportando información inmediata, fiable y a veces concluyente, permitiendo aclarar muchas situaciones clínicas sin respuesta terapéutica aceptable, por lo que se trata de una herramienta diagnóstica esencial. En este capítulo nos centraremos, fundamentalmente, en la valoración funcional y hemodinámica, y en la detección de las complicaciones cardiológicas más frecuentes en el postoperatorio de cirugía cardiaca. (AU)

Surgical complexity as well as comorbidities in patients undergoing cardiac surgery is increasing. Early detection and management of post-surgical complications are key points to reduce morbidity and mortality. Ultrasound technique plays a main rol in cardiopulmonary, hemodynamic and etiological assessment of the critically ill, providing immediate, reliable and, sometimes, conclusive information, clarifying many clinical situations with an inappropriate therapeutic response. For all these reasons ultrasound is an essential diagnostic tool. In this chapter we will focus, mainly, on functional and hemodynamic assessment and on the detection of most common cardiological complications in the postoperative period after cardiac surgery.

Semi-quantitative pulmonary congestion score: prevalence and diuretic management implications after heart failure discharge.

INTRODUCTION: Persistent congestion after heart failure (HF) discharge is associated with a higher risk of readmissions. MATERIAL AND METHODS: eighty-two patients included after HF discharge. The aim of the study was to characterize semiquantitatively the degree of pulmonary congestion and its changes, describing the relationship between these findings and diuretic management. RESULTS: On the first visit, despite the absence of clinical congestion in the majority of patients, half of the had some degree of pulmonary congestion by ultrasound. After global assessment in this initial visit (clinical and ultrasound) the diuretic was lowered in 50 patients (60%), kept the same in 16 (20%) and it was increased in the rest. In the 45 patients without ultrasound congestion, diuretic reduction was attempted in 80%, being this strategy successful in the majority of them. CONCLUSIONS: Lung ultrasound, using simple quantification methods, allows its real incorporation into clinical practice, helping us in the decision making process.

Imágenes Doppler de arterias intrapulmonares dentro de la atelectasia y su impacto en la poscarga del ventrículo derecho con ecocardiografía transesofágica / Doppler images of intrapulmonary arteries within atelectasis and its impact on right ventricular afterload with transesophageal echocardiography

La cirugía cardíaca por toracoscopia videoasistida (VATS) requiere ventilación unipulmonar (VUP) y monitorización con ecografía transesofágica (ETE). Utilizando Doppler color y espectral es posible estudiar el patrón de flujo sanguíneo en los vasos pulmonares dentro del pulmón atelectasiado. El objetivo de este reporte de casos es evidenciar la habilidad de la ETE para detectar el flujo sanguíneo dentro del pulmón atelectásico, así como también valorar la resistencia vascular pulmonar (RVP) y poscarga del ventrículo derecho, utilizando esta misma herramienta. Hallazgos: Tres adultos anestesiados y ventilados mecánicamente programados para cirugía cardíaca por VATS fueron escaneados con ETE cardiopulmonar. Una vez que se realizó la VUP quedando el pulmón derecho sin ventilar, la sonda se giró desde el corazón para lograr un escaneo pulmonar 2D y con Doppler color para detectar el flujo de sangre dentro del parénquima pulmonar consolidado. Se pudo identificar el patrón de flujo correspondiente a las ramas de la arteria intrapulmonar. La RVP fue registrada aplicando Doppler pulsado cardíaco, basal luego de la inducción de anestesia general, a los 20min de la VUP y al finalizar la VUP, luego de realizar una maniobra de reclutamiento alveolar (MRA) que condujo a la resolución completa de la consolidación mencionada. Conclusiones: La ETE cardiopulmonar es una herramienta de imagen semiinvasiva que permite no solo el diagnóstico y estudio de atelectasias inducidas por VUP, sino también el análisis del shunt dentro de esta consolidación y sus posibles consecuencias en la RVP.(AU)

Video-assisted thoracoscopy (VATS) cardiac surgery requires one-lung ventilation (OLV) and transoesophageal ultrasound (TOE) monitoring. Colour and spectral Doppler make it possible to study the pattern of blood flow in the pulmonary vessels within the atelectatic lung. In this case report we describe how TOE can be used to detect blood flow within the atelectatic lung and to assess pulmonary vascular resistance (PVR) and right ventricular afterload. Findings: Three anaesthetised, mechanically ventilated adults scheduled for VATS cardiac surgery were monitored using TOE. After left OLV, the transducer was rotated away from the heart to obtain 2D colour Doppler images of blood flow within the consolidated lung parenchyma. We were able to identify the flow pattern of the intrapulmonary branches of the pulmonary artery. PVR was recorded using pulsed cardiac Doppler at baseline, after induction of general anaesthesia, 20min after OLV and at the end of OLV, and after performing an alveolar recruitment manoeuvre (ARM) that led to complete resolution of the aforementioned consolidation. Conclusions: TOE is a semi-invasive imaging tool that can be used to diagnose and study PVR-induced atelectasis and to analyse the resulting pulmonary shunt and its possible effect on PVR.(AU)
