ABSTRACT

RESUMEN Los pseudoaneurismas de la arteria humeral son infrecuentes, pero pueden asociarse a complicaciones de alta morbilidad como la isquemia de miembro superior. Comunicamos un caso de pseudoaneurisma humeral en el pliegue del codo, que se presentó como tumor pulsátil con leve disminución de la temperatura y parestesias en la mano homolateral de un año de evolución, debido a una punción arterial inadvertida durante la venopunción para extracción de sangre. Se trató con éxito mediante resección quirúrgica más reconstrucción vascular con bypass húmero-cubital y bypass húmero-radial ambos con vena safena. Se discuten las diversas opciones terapéuticas disponibles para los pseudoaneurismas humerales considerando las características anatómicas y la sintomatología del paciente.


ABSTRACT Brachial artery pseudoaneurysms are rare but can be associated with severe complications as ischemia of the upper extremity. We report a case of a brachial artery pseudoaneurysm in the crease of the elbow presenting as a pulsating mass with progressive growth over the past year. The ipsilateral hand was sightly cold and presented paresthesia. The lesion was due to inadvertent arterial puncture during venipuncture. The pseudoaneurysm was successfully treated with surgical resection and vascular reconstruction with a brachial to ulnar artery bypass and brachial to radial artery bypass with saphenous vein graft. The different therapeutic options available for brachial artery pseudoaneurysms are discussed, considering the anatomic characteristics and patients' symptoms.

ABSTRACT

Resumo Fundamento Pacientes com HIV têm maior probabilidade de apresentar doenças cardiovasculares quando comparados à população em geral. Objetivo Este foi um estudo de caso-controle que teve como objetivo avaliar quais fatores estavam associados a uma redução na espessura médio-intimal da carótida (IMT) da carótida e ao aumento na dilatação mediada por fluxo (DMF) da artéria braquial em pacientes com HIV que receberam atorvastatina + aspirina por um período de 6 meses. Métodos Foi realizada uma análise secundária de um ensaio clínico, que incluiu pessoas vivendo com HIV e baixo risco cardiovascular. Um total de 38 pacientes alocados para o braço de intervenção e tratados por 6 meses com uma combinação de atorvastatina + aspirina foram incluídos. Todos os participantes foram submetidos a ultrassonografia da carótida e da artéria braquial, tanto no início quanto no final do estudo. Os casos que responderam com aumento >10% da dilatação braquial (DMF) e redução da espessura médio-intimal da carótida (IMT) foram considerados casos, e aqueles que não responderam foram considerados controles. Avaliamos os fatores associados às respostas positivas obtidas através da IMT e DMF. Resultados A redução do IMT não se associou significativamente a nenhum dos fatores de risco avaliados: idade (p = 0,211), sexo (p = 0,260), tabagismo (p = 0,131) ou tempo de diagnóstico do HIV (p = 0,836). Um aumento na DMF foi significativamente associado com a idade entre aqueles na faixa etária de 40-59 anos, p = 0,015 (OR = 4,37; IC 95%: 1,07-17,79). Conclusões Os indivíduos mais velhos foram mais propensos a apresentar um aumento na DMF após 6 meses de tratamento com atorvastatina + aspirina.


Abstract Background Patients with HIV are more likely to present with cardiovascular disease when compared to the general population. Objective This was a case-control study that aimed to assess which factors were associated with a reduction in the carotid intima-media thickness (IMT) and an increase in the brachial artery flow-mediated dilation (FMD) in HIV patients who received atorvastatin + aspirin during a period of 6 months. Methods A secondary analysis of a clinical trial was conducted, which included people living with HIV infection and low cardiovascular risk. A total of 38 patients allocated to the intervention arm and treated for 6 months with a combination of atorvastatin + aspirin were included. All participants underwent a carotid and brachial artery ultrasound, both at the beginning and the end of the study. Cases that responded with an increase of >10% of the brachial dilatation (FMD) and reduction of the carotid intima-media thickness (IMT) were considered cases, and those who did not respond were considered controls. We assessed the factors associated with the positive responses obtained through IMT and FMD. Results A reduction in the IMT was not significantly associated with any of the evaluated risk factors: age (p=0.211), gender (p=0.260), smoking (p=0.131) or time since HIV diagnosis (p=0.836). An increase in the FMD was significantly associated with age amongst those in the 40-59 age group, p = 0.015 (OR = 4.37; 95% CI: 1.07-17.79). Conclusions Older individuals were more likely to present with an increased FMD after 6 months of treatment with atorvastatin + aspirin.

ABSTRACT

ABSTRACT BACKGROUND: Despite widespread usage of central blood pressure assessment its predictive value among elderly people remains unclear. OBJECTIVE: To ascertain the capacity of central hemodynamic indices for predicting future all-cause and cardiovascular hard outcomes among elderly people. DESIGN AND SETTING: Systematic review and meta-analysis developed at the Del Cuore cardiology clinic, in Antonio Prado, Rio Grande do Sul, Brazil. METHODS: 312 full-text articles were analyzed, from which 35 studies were included for systematic review. The studies included needed to report at least one central hemodynamic index among patients aged 60 years or over. RESULTS: For all-cause mortality, aortic pulse wave velocity (aPWV) and central systolic blood pressure (SBP) were significant, respectively with standardized mean difference (SMD) 0.85 (95% confidence interval, CI 0.69-1.01; I2 96%; P < 0.001); and SMD 0.27 (95% CI 0.15-0.39; I2 77%; P 0.012). For cardiovascular mortality brachial-ankle PWV (baPWV), central SBP and carotid-femoral PWV (cfPWV) were significant, respectively SMD 0.67 (95% CI 0.40-0.93; I2 0%; P 0.610); SMD 0.65 (95% CI 0.48- 0.82; I2 80%; P 0.023); and SMD 0.51 (95% CI 0.32-0.69; I2 85%; P 0.010). CONCLUSIONS: The meta-analysis results showed that aPWV was promising for predicting all-cause mortality, while baPWV and central SBP demonstrated consistent results in evaluating cardiovascular mortality outcomes. Thus, the findings support usage of central blood pressure as a risk predictor for hard outcomes among elderly people. REGISTRATION NUMBER IN PROSPERO: RD42018085264

ABSTRACT

Los traumas vasculares periféricos poseen una frecuencia elevada en relación con las lesiones vasculares y conllevan a una incapacidad significativa a pacientes relativamente jóvenes. La identificación oportuna y el manejo inicial adecuado de este tipo de lesión son muy importantes para su posterior evolución. Este artículo tuvo como objetivo exponer la importancia del tratamiento oportuno del trauma vascular en dos pacientes llegados el mismo día al servicio de urgencias del Hospital Militar Central "Dr. Luis Díaz Soto". Se presenta como primer caso a un paciente masculino de 44 años de edad, con antecedentes de salud aparente. Sufrió una herida de aproximadamente 12 cm en el brazo izquierdo, que se acompañó de sangramiento e hipotensión arterial. Se le colocó injerto protésico y se le realizó anastomosis término-terminal en la arteria humeral porque presentaba sección completa de esta; su evolución fue favorable. El segundo caso se trata de un paciente masculino de 60 años de edad, con antecedentes de salud aparente. Sufrió un trauma en el antebrazo izquierdo que le provocó una herida de alrededor de 8 cm, con sangramiento, palidez y frialdad del tercio distal del antebrazo, cianosis reversible de la mano, impotencia funcional, ausencia de pulso radial e hipotensión arterial. Se le realizó anastomosis término-terminal de arteria radial porque presentaba sección completa de esta y su evolución resultó favorable. El tratamiento oportuno y acertado del trauma vascular evitó la pérdida de la vida de los pacientes, disminuyó la presencia de complicaciones, aseguró una evolución rápida y redujo incapacidades en estos(AU)


Peripheral vascular traumas have a high frequency in relation to vascular lesions, and lead to significant disability in relatively young patients. Timely identification and adequate initial management of this type of lesion are very important for its subsequent evolution. This article aimed to show the importance of timely treatment of vascular trauma in two patients who arrived on the same day at the emergency service of Dr. Luis Díaz Soto Central Military Hospital. The first case presented corresponds to a 44-year-old male patient apparently without previous heath conditions. He had a wound of approximately twelve centimeters on the left arm, which was accompanied by bleeding and arterial hypotension. The patient was placed a prosthetic graft and performed an end-to-end anastomosis in the brachial artery because it was completely sectioned. The patient's evolution was favorable. The second case corresponds to a 60-year-old male patient with an apparent health history. He suffered a trauma to his left forearm that caused a wound of about 8 cm, with bleeding, paleness and coldness of the distal third of the forearm, reversible cyanosis of the hand, functional impotence, absence of radial pulse and arterial hypotension. End-to-end anastomosis of the radial artery was performed because the patient presented complete section of the artery and his evolution was favorable. Timely and correct treatment of vascular trauma prevented the loss of life in both patients, reduced the presence of complications, ensured a rapid evolution, and reduced their disabilities(AU)

ABSTRACT

Introducción: Las enfermedades cardiovasculares de mayor prevalencia y la hipertensión arterial tienen como sustento la aterosclerosis y la disfunción endotelial. La evaluación no invasiva de aterosclerosis subclínica constituye un complemento para la estratificación del riesgo cardiovascular en la evaluación del paciente hipertenso. Objetivo: Determinar la utilidad del diámetro basal de la arteria braquial en la evaluación del paciente con hipertensión arterial esencial. Método: Se realizó un estudio transversal analítico que incluyó 30 pacientes con hipertensión arterial esencial, a quienes se les realizó ultrasonografía para medir el diámetro basal de la arteria braquial, la vasorreactividad dependiente del endotelio y el grosor íntima media carotídeo, así como se precisó su riesgo cardiovascular, el tiempo de evolución y grado de la hipertensión arterial. Para determinar la asociación entre el diámetro arterial y el resto de las variables se utilizaron pruebas estadísticas como ANOVA de una vía y el coeficiente de correlación de Pearson. Resultados: La disfunción endotelial estuvo presente en 83,3 por ciento de los pacientes estudiados. Tanto el grosor del complejo íntima media carotídeo como la vasorreactividad dependiente del endotelio fueron adecuados marcadores de la enfermedad aterosclerótica. El diámetro basal de la arteria braquial tuvo una correlación inversa con la vasorreactividad dependiente del endotelio, y mostró valores medios esperados en relación a la presencia del tabaquismo, y con los peores grados de la enfermedad hipertensiva y el riesgo cardiovascular. Conclusiones: El diámetro basal de la arteria braquial no mostró la asociación esperada para la evaluación del paciente hipertenso esencial en la población estudiada(AU)


Introduction: The most prevalent cardiovascular diseases and high blood pressure are supported by atherosclerosis and endothelial dysfunction. The non-invasive assessment of subclinical atherosclerosis complements the cardiovascular risk stratification when evaluating hypertensive patients. Objective: To determine the value of the basal diameter of the brachial artery in assessing patients suffering from essential arterial hypertension. Method: An analytical cross-sectional study was carried out in 30 patients with essential arterial hypertension. They underwent ultrasonography to measure the basal diameter of the brachial artery, endothelium-dependent vasoreactivity and carotid mean intima thickness, as well as the cardiovascular risk, time of evolution and degree of arterial hypertension. Statistical tests such as one-way ANOVA and Pearson's correlation coefficient were used to determine the association between arterial diameter and the rest of the variables. Results: Endothelial dysfunction was present in 83.3% of the studied patients. Both the thickness of the carotid media intima complex and endothelium-dependent vasoreactivity were adequate markers for atherosclerotic disease. The basal diameter of the brachial artery had inverse correlation with endothelium-dependent vasoreactivity, and it showed expected mean values in relation to the presence of smoking, and with the worst degrees of hypertensive disease and cardiovascular risk. Conclusions: The basal diameter of the brachial artery did not show the expected association for the evaluation of essential hypertensive patients in the studied population(AU)

ABSTRACT

ABSTRACT Background The ambulatory arterial stiffness index (AASI), derived from 24 h ambulatory blood pressure monitoring (ABPM) can be a good indicator of arterial stiffness. Aim To assess the correlation between AASI and brachial-ankle pulse wave velocity (baPWV), ankle-brachial index (ABI) and cardio-ankle vascular index (CAVI) in patients with type 2 diabetes mellitus without hypertension. Material and Methods Cross sectional study in 28 diabetic patients aged 49 ± 7 years (40% women). AASI was calculated as 1 minus the regression slope of diastolic on systolic blood pressure, using ABPM data. ABPM was measured in the arm using an oscillometric device. ABI was calculated as the ratio between ankle and brachial systolic blood pressure. CAVI was derived from pulse wave velocity using the Vasera VS-1000 device. Correlations were calculated using a bivariate Spearman correlation. Results The mean values for AASI, ABI, baPWV and CAVI were 0.39 ± 0.14, 1.14 ± 0.09, 15.15 ± 2.71 m/s and 7.60 ± 1.90, respectively. There was a significant negative correlation between AASI and ABI (r = -0.491, p < 0.01). Conclusions In these diabetic patients, there was an association between AASI, an arterial stiffness marker and ABI, an indicator for the presence of atherosclerosis.


Antecedentes El índice de rigidez arterial ambulatorio (AASI), derivado del monitoreo ambulatorio de presión arterial de 24 h (MAPA), puede ser un buen indicador de rigidez arterial. Objetivo Evaluar la correlación entre el AASI y la velocidad de onda de pulso braquial (VOP), el índice tobillo-brazo (ITB) y el índice vascular cardio-tobillo (CAVI) en pacientes con diabetes mellitus tipo 2 sin hipertensión arterial. Material y Métodos Estudio transversal en 28 pacientes con diabetes de 49 ± 7 años (40% mujeres). El AASI se calculó como 1 menos la pendiente de regresión de la presión arterial diastólica sobre la sistólica, usando datos del MAPA de 24 h, el cual se midió en el brazo, usando un dispositivo oscilométrico. El ITB se calculó como la razón entre la presión arterial sistólica del tobillo sobre la del brazo. El CAVI se derivó de la velocidad de onda de pulso medida con el dispositivo Vasera VS-1000. Para el análisis estadístico se utilizó el coeficiente de correlación bivariada de Spearman. Resultados Los valores de AASI, VOP, ITB y CAVI fueron 0.39 ± 0.14, 1.14 ± 0.09, 15.15 ± 2.71 m/s y 7.60 ± 1.90, respectivamente. Hubo una correlación negativa significativa entre AASI e ITB (r = -0.491, p < 0.01). Conclusiones Hay una asociación entre AASI, un marcador de rigidez arterial e ITB, un indicador de aterosclerosis, en estos pacientes con diabetes mellitus tipo 2.

ABSTRACT

Las supracondíleas son el tipo más común de fracturas en la articulación del codo durante la infancia, con un pico de presentación entre los cinco y siete años. Además constituyen el segundo tipo de fracturas más frecuente en la población pediátrica en general. El mecanismo típico de la lesión es una caída desde la altura del paciente sobre la palma de la mano con el codo en hiperextensión. El diagnóstico se basa en la sospecha clínica, según el mecanismo de la lesión y la edad del paciente, además de la radiografía simple del codo en dos proyecciones. La clasificación de Gartland es la más usada para establecer la gravedad de la fractura y guiar el tratamiento, que puede ser ortopédico en fracturas no desplazadas. El método de elección para corrección de las desplazadas es la reducción cerrada y fijación con pines percutáneos. La complicación más común es la neuropraxia del nervio mediano. Otras complicaciones son la lesión de la arteria braquial, el síndrome compartimental, la isquemia de Volkmann, el deslizamiento de los pines y el cúbito varo.


Supracondylar are the most common fractures in the elbow joint during childhood with a peak between the ages five to seven. Besides, they are the second most common type of fracture in the pediatric population in general. The typical cause of the injury is the patient falling from their own height on the palm of the hand with the elbow in hyperextension. The diagnosis is based on the clinical suspicion according to the injury mechanism and the age of the patient, in addition to a standard elbow X-ray from two views. The Gartland classification is the most used instrument to establish the severity of the fracture and to guide the treatment, which can be orthopedic in non-displaced fracture, whereas the method of choice for correction of displaced fractures is closed reduction and percutaneous fixation. The most common complication is the neuropraxia of the median nerve. Others are the brachial artery injury, compartment syndrome, Volkamm ischemic contracture, sliding of the pins and ulna varus.

ABSTRACT

ABSTRACT The present study aimed to evaluate the acute behavior of the brachial artery resistance index (BARI) and popliteal artery resistance index (PARI) in response to low intensity strength exercises involving small (SMG) and large muscle groups (LMG) performed with and without blood flow restriction. Eleven men (age 23 ± 3.29 years) underwent a four-arm, randomized, cross-over experiment: Small muscle group exercise (SMG), small muscle groups with blood flow restriction (SMG+BFR), large muscle groups (LMG) and large muscle groups with blood flow restriction (LMG+BFR). The behavior of BARI and PARI was evaluated at rest, immediately after exercise, and at 15 and 30 minutes during recovery. Data analysis showed a significant reduction of the BARI from rest to post-exercise only in the protocols involving SMG, regardless of the BFR (p <0.05). Protocols involving LMG, with or without BFR, did not affect PARI (p> 0.05), but were efficient to promote significant increases in BARI (p <0.05) immediately after exercise. Our findings indicate that the exercises involving SMG, regardless of BFR, are efficient to promote local vasodilatation (brachial artery), but without systemic effects. None of the analyzed protocols affected the PARI behavior.


RESUMO O presente estudo objetivou avaliar o comportamento agudo do índice de resistência da artéria braquial (IRAB) e da artéria poplítea (IRAP) em resposta a exercícios de força de baixa intensidade envolvendo pequenos (PGM) e grandes grupos musculares (GGM), realizado com e sem restrição de fluxo sanguíneo. Onze homens (idade 23 ± 3,29 anos) realizaram um experimento randomizado, cruzado, com quatro braços: Exercício para pequenos grupos musculares (PGM), pequenos grupos musculares com restrição de fluxo sanguíneo (PGM+RFS), grandes grupos musculares (GGM) e grandes grupos musculares com restrição de fluxo sanguíneo (GGM+RFS). O comportamento de IRAB e IRAP foi avaliado em repouso, mediatamente após o exercício, e aos 15 e 30 minutos da recuperação. A análise dos dados mostrou uma redução significativa do IRAB do repouso para o pós-exercício apenas nos protocolos de PGM com ou sem RFS (p <0,05). Protocolos envolvendo GGM, independentemente do BFR, não afetaram o IRAP (p> 0,05), porém, foram eficientes para promover aumentos significativos do IRAB (p <0,05) imediatamente após o exercício. Nossos achados indicam que os exercícios envolvendo PGM, independentemente da BFR, são capazes de promover a vasodilatação local (artéria braquial), porém, sem efeitos sistêmicos. Nenhum dos protocolos analisados afetou o comportamento do IRAP.

ABSTRACT

SUMMARY OBJECTIVE Our aim is to determine whether radiation affects the endothelial function of hospital staff working in the radiation unit for diagnostic and therapeutic purposes. We have evaluated endothelial function with vascular imaging parameters such as flow-mediated dilatation (FMD) and aortic stiffness index (ASI). METHODS A total of 75 employees, 35 of whom are exposed to radiation due to their profession and 40 as the control group, were included in our single-centered study. Demographic data, FMD, aortic stiffness, and echocardiographic findings of the two groups were compared. RESULTS There were no significant differences in demographic data. Median FMD values tended to be lower in the radiation exposure group [7.89 (2.17-21.88) vs. 11.69 (5.13-27.27) p=0.09]. The FMD value was significantly lower in the catheter laboratory group than in the radiation-exposed (p=0.034) and control (p=0.012) groups. However, there was no statistically significant difference between the non-catheter lab radiation exposed group and the control group (p=0.804). In addition, there was no statistically significant difference in the ASI value between the groups (p=0.201). CONCLUSION We have found that FMD is decreased among hospital staff working in radiation-associated areas. This may be an early marker for radiation-induced endothelial dysfunction.


RESUMO OBJETIVO O nosso objetivo é determinar se a radiação afeta a função endotelial de funcionários do hospital que trabalham em unidades com exposição à radiação para fins diagnósticos e terapêuticos. Avaliamos a função endotelial com parâmetros de imagens vasculares, tais como dilatação fluxo-mediada (FMD) e o índice de rigidez aórtica (ASI). METODOLOGIA Um total de 75 funcionários, 35 expostos à radiação devido à sua ocupação e 40 como grupo de controle, foram incluídos em nosso estudo monocêntrico. Os dados demográficos, de FMD, rigidez aórtica e ecocardiográficos dos dois grupos foram comparados. RESULTADOS Não houve diferenças significativas nos dados demográficos. Os valores médios de FMD, em geral, foram mais baixos no grupo de exposição à radiação [7,89 (2,17-21,88) e 11,69 (5,13-27,27) p=0,09]. O valor de FMD foi significativamente menor no grupo laboratorial com cateter do que no exposto à radiação (p=0,034) e no de controle (p=0,012). No entanto, não houve diferença estatisticamente significativa entre o grupo laboratorial sem cateter e exposto à radiação e o grupo de controle (p=0,804). Além disso, não houve diferença estatisticamente significativa quanto ao valor de ASI entre os grupos (p=0,201). CONCLUSÃO Observamos que a FMD é menor entre funcionários que trabalham em setores hospitalares associados à radiação. Isso pode ser um marcador inicial de disfunção endotelial induzida por radiação.

ABSTRACT

Abstract Background: Psoriasis correlates with metabolic disorders, early atheromatosis and increased cardiovascular risk. Objectives: To assess markers of cardiovascular disease in psoriatic patients. Methods: Cross-sectional, observational study involving 11 psoriatic participants and 33 controls. Anthropometric, biochemical, hemodynamic and imaging parameters were evaluated. Arterial stiffness was assessed by oscillometric measurement of the brachial artery. Intima-media thickness (IMT) and left ventricular diastolic function were assessed by Doppler echography and echocardiography. Between-group comparisons of numerical variables were performed by the Student's t-test or Wilcoxon Mann-Whitney test for independent samples. Significance level was set at 5%. Results: Psoriatic patients showed increased pulse wave velocity (PWV) (9.1 ± 1.8 vs 8.0 ± 2 m/s, p = 0.033), IMT of the left common carotid artery (p = 0.018) and a higher percentage of patients above the 75th percentile according to the ELSA table when compared with controls (54.5 vs 18.2%, p = 0.045). Psoriatic patients also showed an increase in peripheral/central systolic blood pressure (137.1 ± 13.2 vs 122.3 ± 11.6 mmHg, p = 0.004)/(127 ± 13 vs 112.5 ± 10.4 mmHg, p = 0.005), peripheral/central diastolic blood pressure (89.9 ± 8.9 vs 82.2 ± 8, p = 0.022)/(91 ± 9.3 vs 82.2 ± 8.3, p = 0.014), total cholesterol (252 ± 43.5 vs 198 ± 39.8 mg/dL, p < 0.001), LDL cholesterol (167 ± 24 vs 118 ± 40.8 mg/dL, p < 0.001) and C-reactive protein (7.6 ± 35.4 vs 1 ± 1.2 mg/L p < 0.001) compared with controls. Conclusion: Psoriasis patients show increased PWV, IMT, peripheral and central blood pressures, and serum cholesterol and C-reactive protein levels, denoting a higher cardiovascular risk.


Resumo Fundamento: A psoríase correlaciona-se a distúrbios metabólicos, ateromatose precoce e aumento do risco cardiovascular. Objetivos: Avaliar marcadores de doença cardiovascular na população psoriásica. Métodos: Estudo observacional transversal, envolvendo 11 participantes psoriásicos e 33 controles. Foram avaliados parâmetros antropométricos, laboratoriais, hemodinâmicos e de imagem. A rigidez arterial foi avaliada por oscilometria da artéria braquial. A espessura médio-intimal (EMI) e a função diastólica do ventrículo esquerdo foram avaliadas por meio da ecografia e ecocardiografia Doppler.

ABSTRACT

O procedimento da medida indireta da pressão arterial (PA) é usado na prevenção, diagnóstico e tratamento de pacientes com hipertensão arterial nas diversas fases de evolução da doença. Embora o procedimento seja considerado simples e de fácil execução, muitos profissionais realizam-no de forma inapropriada e sem o devido conhecimento científico, o que pode interferir na fidedignidade dos resultados obtidos. Objetivo: Identificar na literatura as falhas no cumprimento da técnica de medida indireta da PA realizada por profissionais de saúde. Método: Trata-se de uma revisão integrativa que analisou estudos publicados entre 2013 e 2017, nas bases de dados Cumulative Index to Nursing and Allied Health Literature, Base de Dados de Enfermagem, Scientific Electronic Library Online, Medical Literature Analysis and Retrieval System, Literatura latino-americana e do Caribe em ciências da saúde, Índice Bibliográfico Espanhol em Ciências da Saúde e Biblioteca COCHRANE. Sete artigos compuseram a amostra do estudo, a qual foi analisada com relação à identificação do artigo, características metodológicas e avaliação do rigor metodológico. Resultados: Cinco estudos foram desenvolvidos no Brasil (71,5%), um no Egito (14,3%) e um nos Estados Unidos (14,3%). Os achados apontaram falhas relacionas à etapa do preparo do paciente, à etapa do procedimento e à etapa do registro da PA. Conclusão: Inúmeras falhas foram identificadas durante a realização do procedimento de medida indireta da PA, o que reforça a necessidade do desenvolvimento de estudos de intervenção que possam promover o conhecimento teórico-prático dos profissionais da saúde


The indirect blood pressure (BP) measurement procedure is used in the prevention, diagnosis and treatment of patients with arterial hypertension in the various phases of disease progression. Although the procedure is considered simple and easy to perform, many professionals perform it incorrectly and without adequate scientific knowledge, which may interfere with the reliability of the results obtained. Objective: To identify in the literature failures in compliance with the technique of indirect BP measurement performed by health professionals. Method: This is an integrated review that analyzed studies published between 2013 and 2017 in the Cumulative Index to Nursing and Allied Health Literature, the Brazilian Nursing Database (BDENF), the Scientific Electronic Library Online, the Medical Literature Analysis and Retrieval System, the Latin American and Caribbean Health Sciences Literature, the Spanish Bibliographical Health Sciences Index, and the COCHRANE Library databases. Seven articles made up the study sample, which was analyzed in terms of article identification, methodological characteristics and assessment of methodological rigor. Results: Five studies were developed in Brazil (71.5%), one in Egypt (14.3%) and one in the United States (14.3%). The findings pointed to failures related to the patient preparation stage, the procedure stage and the BP recording stage. Conclusion: Numerous failures were identified during the indirect BP measurement procedure, which reinforces the need to develop intervention studies that can promote the theoretical-practical knowledge of health professionals

ABSTRACT

Background: Patients with polycystic ovarian syndrome (PCOS) have an increased prevalence of metabolic syndrome and traditional atherosclerotic risk factors, such as dyslipidemia, diabetes and hypertension. Endothelial function and vascular stiffness are surrogate markers of early atherosclerosis, able to predict cardiovascular events. Objective: To compare endothelial function and pulse wave reflection between women with PCOS and healthy controls. Methods: Observational and cross-sectional study that included women with PCOS, age between 18 and 40 years-old and body mass index between 25.0 and 35.0 kg/m2, and healthy controls. Rotterdan criteria was used to diagnose PCOS. Subjects underwent clinical and anthropometric evaluation, laboratory and hormonal assays and imaging tests to measure pulse wave velocity (PWV), augmentation index (AIx) and brachial artery flow-mediated vasodilation (FMD). Kolmogorov-Smirnov test showed normal distribution of most parameters. Unpaired Student t-test was used with significance level established at p < 0.05.Results: A total of 52 patients were included, 29 (56%) in PCOS group and 23 (44%) in control group. Clinical and laboratory parameters were similar between the groups. Women with PCOS had lower FMD (8.8 ± 1.0 vs 12.8 ± 1.2%, p = 0.021); PWV and AIx were similar between the groups (7.5 ± 0.2 vs 7.5 ± 0.3 m/s, p = 0.671 and 21.0 ± 1 vs. 20 ± 2%, p = 0.716, respectively). In the PCOS group, women with higher testosterone levels had higher AIx (25 ± 2 vs. 17 ± 3%, p = 0.045). Conclusions: PCOS women had endothelial dysfunction and those with higher testosterone levels had higher pulse wave reflection as compared with controls

ABSTRACT

Background Elevated arterial stiffness is associated with increased cardiovascular mortality. The relationship between arterial stiffness and critical limb ischemia (CLI) is not well established. Objectives The objective of this study is to analyze the relationship between arterial stiffness indices and the degree of limb ischemia measured by the ankle-brachial index (ABI). Methods A cross-sectional study comparing patients with CLI and controls. Arterial stiffness was measured using brachial artery oscillometry. The arterial stiffness indices pulse wave velocity (PWV) and augmentation index normalized to 75 beats/min (AIx@75) were determined. Multiple linear regression was applied to identify predictors of arterial stiffness indices. Results Patients in the CLI group had higher PWV (12.1±1.9 m/s vs. 10.1±1.9 m/s, p < 0.01) and AIx@75 (31.8±7.8% vs. 17.5±10.8%, p < 0.01) than controls. Central systolic pressure was higher in the CLI group (129.2±18.4 mmHg vs. 115.2±13.1 mmHg, p < 0.01). There was an inverse relationship between AIx@75 and ABI (Pearson coefficient = 0.24, p = 0.048), but there was no relationship between ABI and PWV (Pearson coefficient = 0.19, p = 0.12). In multiple regression analysis, reduced ABI was a predictor of elevated levels of AIx@75 (β = -25.02, p < 0.01). Conclusions Patients with CLI have high arterial stiffness measured by brachial artery oscillometry. The degree of limb ischemia, as measured by the ABI, is a predictor of increased AIx@75. The increased AIx@75 observed in CLI may have implications for the prognosis of this group of patients with advanced atherosclerosis


A rigidez arterial aumentada está associada ao aumento da mortalidade cardiovascular. A relação entre rigidez arterial e isquemia crítica do membro (IC) não está bem estabelecida. Objetivos O objetivo deste estudo é analisar a relação entre índices de rigidez arterial e o grau de isquemia de membro medido pelo índice tornozelo-braço (ITB). Métodos Foi feito um estudo transversal em pacientes com IC e controles. A rigidez arterial foi medida usando a oscilometria da artéria braquial. Os índices de rigidez arterial mensurados foram a velocidade de onda de pulso (VOP) e o índice de aumentação corrigido para a frequência cardíaca de 75 batimentos/min (AIx@75). Regressão linear múltipla foi aplicada para identificar preditores dos índices de rigidez arterial. Resultados Pacientes do grupo IC tiveram VOP (12,1±1,9 m/s vs. 10,1±1,9 m/s, p < 0,01) e AIx@75 (31,8±7,8% vs. 17,5±10,8%, p < 0,01) maiores que controles. Pressão sistólica central foi maior no grupo IC (129,2±18,4 mmHg vs. 115,2±13,1 mmHg, p < 0,01). Houve uma relação inversa entre o AIx@75 e o ITB (coeficiente de Pearson = 0,19, p = 0,12). A análise de regressão múltipla mostrou que o ITB reduzido foi um preditor de elevação do AIx@75 (β = -25,02, p < 0,01). Conclusões Pacientes com IC têm elevada rigidez arterial medida por oscilometria da artéria braquial. O grau de isquemia do membro, medido pelo ITB, é um preditor do AIx@75 elevado. O aumento do AIx@75 na IC pode ter implicações de prognóstico no grupo de pacientes com aterosclerose avançada

ABSTRACT

Background: Iron is a pro-oxidant cofactor that may be linked to cardiovascular disease (CVD) progression and reduction of body iron stores have been hypothesized to reduce the risk of CV disease. Aim: The aim of this study is to assess reduction in CVD risk susceptibility among regular blood donors compared with nondonors using ultrasound brachial artery flow-mediated dilation (BAFMD). Settings and Design: A prospective comparative study designed to establish the difference between mean flow-mediated dilatation (FMD) in the patients who are regular blood donors compared with nondonors recruited from a Teaching Hospital donor clinic. Materials and Methods: Data were collected over 7 months from December 2014 to June 2015. 100 eligible regular male blood donors, aged 21­50 years, were selected from a Teaching Hospital blood donor records and their BAFMD assessed. 50 nondonors/ first time donors, of equivalent age group, consecutively were assessed for comparison. Serum markers of iron stores, markers of oxidative stress and other related cardiac risk factors were also assessed in all patients. Results: BAFMD was significantly greater in regular blood donors when compared with nondonors (13.95% ± 7.02% vs. 8.20% ± 4.19%, P = 0.000). Serum ferritin was significantly decreased in regular blood donors when compared with nondonors (mean value 41.92 ng/ml ± 23.12 ng/ml vs. 61.97 ± 30.19 ng/ml, P = 0.000), but Hb did not differ between the groups. High FMD was significantly associated with high C-high-density lipoprotein and low C-LDL (r = −0.215*, P = 0.032, r = 0.188, P = 0.031, r = 0.193, P = 0.027, r = 0.0279, P = 0.002, r = 0.139, P = 0.084). LDL was decreased in regular blood donors compared with nondonors. Conclusion: The study provides prognostic information for assessing ultrasound BAFMD as a cardiac risk marker. Regular blood donors have enhanced cardiovascular function with increased flow-mediated dilation, decreased body iron stores, and decreased oxidative stress compared with nondonors

ABSTRACT

The authors report a rare variation of the vasculature in the upper limbs of an 84-year-old male cadaver. A high bifurcation of the brachial artery occurred bilaterally at the proximal one-third of each arm. The radial arteries were larger than the ulnar arteries and gave origin to the common interosseous arteries. At the cubital fossa, the ulnar arteries traversed medial to the median nerves, continuing superficial to all forearm muscles except the palmaris longus tendon, characteristic of superficial brachioulnar arteries. The aforementioned variations have rarely been reported in previous literature and demonstrate important clinical significance in relation to accidental intra-arterial injections, errors in blood pressure readings, as well as orthopedic, plastic, and vascular surgeries of the upper limbs.

ABSTRACT

Entrapment neuropathies of the peripheral nervous system are frequently encountered due to anatomical variations. Median nerve is the most vulnerable nerve to undergo entrapment neuropathies. The clinical complications are mostly manifested by median nerve impingement in forearm and wrist areas. Median nerve entrapment could also occur at the arm, due to the presence of ligament of Struthers. Here we report a rare case of proximal entrapment of median nerve and brachial artery in the arm by an abnormally formed musculo-fascial tunnel. The tunnel was formed by the muscle fibers of brachialis and medial intermuscular septum in the lower part of arm. Due to this, the median nerve coursed deep, below the tunnel and continued distally into the forearm, underneath the pronator teres muscle and hence did not appear as a content of cubital fossa. The present entrapment of neurovascular structures in the tunnel might lead to pronator syndromes or other neurovascular compression syndromes.

ABSTRACT

BACKGROUND/AIMS: The strategy of access care at out center involves the use of ultrasound (USG) in case of physical examination (PE) abnormality. USG determines the need of angiography. This study investigated the possible association between the need for percutaneous transluminal angioplasty (PTA) and hemodynamic parameters of USG. The study also assessed the effects of this monitoring strategy on outcomes in comparison with a historical control. METHODS: A retrospective study of the medical records of 127 patients (65 PTA, 62 non-PTA) was conducted. Data were analyzed using logistic regression analysis and receiver operating characteristic curve. Fistula outcomes and intervention rates were calculated and compared with 100 historic controls. RESULTS: Logistic regression analysis showed that brachial artery flow volume (FV) 0.63 was independently associated with the need for PTA. This monitoring strategy showed an a reduction in thromboses (0.02 ± 0.11 events/arteriovenous fistula [AVF]-year vs. 0.07 ± 0.23 events/AVF-year, p = 0.046), reduction in central venous catheter placement (0.01 ± 0.05 events/AVF-year vs. 0.06 ± 0.22 events/AVF-year, p = 0.010), reduction in access loss (0.02 ± 0.13 events/AVF-year vs. 0.19 ± 0.34 events/AVF-year, p = 0.015), and increase in access selective repair (0.49 ± 0.66 events/AVF-year vs. 0.21 ± 0.69 events/AVF-year, p = 0.003), compared to historic control. CONCLUSIONS: There was significant stenosis if brachial artery FV was 0.63 for PE abnormality. These parameters should be used as markers for assessing PTA risk in hemodialysis patients. Addition of USG to determine the need of angiography after detection of PE abnormality leads to decreases in access thrombosis, catheter placement, and access loss despite increasing access intervention rates compared to clinical monitoring.

ABSTRACT

Antiphospholipid antibodies may be produced in cases involving autoimmune diseases and can sometimes be caused by infections, such as Mycoplasma pneumoniae infection. However, antiphospholipid antibodies causing thrombosis associated with M. pneumoniae pneumonia in children have rarely been reported. We report a case of an 8-year-old boy with M. pneumoniae pneumonia with antiphospholipid antibodies, complicated by brachial artery thrombosis. He was found to have antiphospholipid antibodies and low protein S levels. The brachial artery thrombus was removed via thrombectomy. The titers of antiphospholipid antibodies turned normal within 5 months. This is a rare case of M. pneumoniae infection with brachial artery thrombosis associated with transient antiphospholipid antibodies.

ABSTRACT

PURPOSE: Isometric handgrip exercise (IHE) is an easy and accessible form of exercise that has beneficial effects on blood pressure (BP). However, it remains unclear whether IHE is similar benefits on arterial stiffness and endothelial function compared with aerobic exercise (AE) in elderly hypertensive patients. The aim of this study was to compare the effects of IHE versus AE on arterial stiffness and endothelial function in elderly hypertensive patients.METHODS: We conducted a randomized controlled trial with a three-arm design. Fifty-four elderly hypertensive patients (15 men; mean age, 69±6 years; systolic blood pressure, 131.2±14.7; diastolic blood pressure, 80.2±7.9 mm Hg) were randomized to IHE training (n=18), AE training (n=21), or non-exercise control group (n=21) for 12 weeks. Bilateral IHE training was performed four times of 2 minutes at 30% of maximal voluntary contraction with three times per week. AE training was performed brisk walking for 30 minutes at moderate intensity with three times per week. Carotid-femoral pulse wave velocity (PWV), augmentation index heart rate corrected (AIx@75 bpm) and brachial artery flow-mediated vasodilation (FMD) as indices of arterial stiffness and endothelial function were measured at baseline and after the intervention.RESULTS: Following 12-week intervention, resting BP was significantly decreased in both IHE (p=0.001) and AE groups (p=0.002). AIx@75 bpm and FMD were unchanged in the all groups. However, PWV was significantly decreased in both IHE and AE groups (IHE, 10.9±2.3 to 9.9±2.1 m/s [p<0.001]; AE, 10.5±2.0 to 9.4±1.6 m/s [p=0.001]), without any change in the control group.CONCLUSION: These findings suggest that both IHE and AE trainings were comparable effect in improving arterial stiffness in elderly hypertensive patients.
