ABSTRACT

Desde 1995 hasta la fecha la asociación entre patologías derivadas los embarazos hipertensivos y las enfermedades cardiovasculares ha generado un gran volumen de potentes evidencias epidemiológicas y clínicas. Los propósitos de esta revisión son varios. Mostrar la consistencia y magnitud de la evidencia científica. Integrar los riesgos/enfermedades cardiovasculares y los problemas obstétricos a través de la disfunción endotelial. Preconizar el seguimiento postparto de la hipertensa embarazada, como una ventana de oportunidad para beneficiar la salud de las mujeres y sus hijos. Incluir la historia obstétrica como factor de riesgo de enfermedad coronaria. Proponer cuestionarios adaptables a las prácticas locales para facilitar la pronta incorporación de los índices de riesgo obstétrico y cardiovascular en dos etapas de la vida de una mujer. Ha llegado el momento para que los equipos obstétricos, cardiológicos y las pacientes jueguen un rol en la prevención de los riesgos y enfermedades cardiovasculares.


From 1995 onwards the association between hypertensive pregnancies and cardiovascular disease has generated a great volume of epidemiologic and clinical evidence. The purposes of this review are several. To demonstrate the consistence and weight of the scientific evidence. To integrate cardiovascular risks/diseases and obstetric complications through the link of endothelial dysfunction. To advocate postpartum follow-up after a hypertensive pregnancy as a window of opportunity to benefit the health of mothers and offsprings. To include the obstetrical history as a risk factor for coronary disease. To propose questionnaires adaptable to local practices to incorporate cardiovascular and obstetrical indexes in two stages of a woman's lifetime. The time has come for obstetrical teams, cardiologists and patients to play a preventive role regarding cardiovascular risks and diseases.

ABSTRACT

Abstract Background: Lichen planus is a chronic inflammatory mucocutaneous disease. Recent studies have suggested that it is associated with an increased risk of cardiovascular comorbidities. Objective: The purpose of this study was to assess and compare arterial stiffness and cardiovascular hemodynamics in patients with lichen planus and a healthy control group. Methods: Fifty-five patients with lichen planus and 42 healthy controls were enrolled. All patients underwent echocardiographic examination, and arterial stiffness was measured using applanation tonometry. Results: No statistically significant difference was determined between the patient and control groups in terms of arterial stiffness, but stiffness was markedly higher in patients with erosive lichen planus compared to the control group and other patients (p = 0.006, and p = 0.023, respectively). Moderate positive correlation was determined between duration of disease and arterial stiffness. Impairment of systolic and diastolic functions was also determined in patients with lichen planus compared to the control group (p < 0.001, and p = 0.005, respectively). Study limitations: Relatively low number of patients. Conclusion: The positive correlation observed between duration of disease and arterial stiffness in patients with lichen planus suggests that these patients should be followed-up in terms of cardiovascular risk in the presence of resistant and long-term disease, particularly in case of erosive lichen planus.

ABSTRACT

Resumen La pandemia por COVID-19 decretada por la Organización Mundial de la Salud (OMS) desde el 12 de marzo de 2020 está produciendo estragos a nivel mundial y es un verdadero reto económico, social y sanitario. Aunque las manifestaciones clínicas del COVID-19 son síntomas respiratorios, algunos pacientes también tienen síntomas cardiológicos. Dentro de los pacientes con afecciones cardiológicas2 suponen un grupo de mayor riesgo y que de hecho son un grupo especialmente vulnerable, por su mayor riesgo de contagio y mayor gravedad en caso de adquirir la enfermedad1 aquellos con insuficiencia cardiaca (IC), incluyendo al trasplante cardiaco (TC) y las asistencias ventriculares, así como los pacientes con hipertensión arterial pulmonar (HAP). La IC es la principal patología cardiovascular crónica y los pacientes en este grupo son los más vulnerables para el desarrollo de cuadros clínicos más graves tras sufrir la infección, y en mayor medida los casos con IC avanzada3. De hecho, la IC es unas de las complicaciones más frecuentes en los pacientes con COVID-194. De igual forma, los pacientes trasplantados que requieren de los inmunosupresores para evitar el rechazo del injerto, constituyen una población especialmente susceptible a la infección y a desarrollar procesos más graves. Esta situación ha hecho que la Asociación Nacional de Cardiólogos de México (ANCAM) y la Sociedad Mexicana de Cardiología (SMC) junto con sus respectivos capítulos, hayan elaborado las siguientes recomendaciones para el personal médico, que participa en la atención de este grupo especial de pacientes en los diferentes escenarios clínicos, que padezcan o no, COVID-19.


Abstract The COVID-19 pandemic decreed by the World Health Organization (WHO) since March 12, 2020 is wreaking havoc globally and it is a true economic, social and health challenge. Although the clinical manifestations of COVID-19 are respiratory symptoms, some patients also have cardiological symptoms. Among patients with cardiological conditions2 they represent a group of higher risk and, in fact, they are a particularly vulnerable group, due to their higher risk of contagion and greater severity in case of acquiring the disease1 those with heart failure (HF), including heart transplant (CT) and ventricular assists, as well as patients with pulmonary arterial hypertension (PAH). HF is the main chronic cardiovascular disease and patients in this group are the most vulnerable for the development of more serious clinical symptoms after suffering the infection, and to a greater extent cases with advanced HF3. In fact, HF is one of the most frequent complications in patients with COVID-194. Likewise, transplant patients who require immunosuppressants to avoid graft rejection, constitute a population especially susceptible to infection and to develop more serious processes. This situation has made the National Association of Cardiologists of Mexico (ANCAM) and the Mexican Society of Cardiology (SMC) together with their respective chapters, have prepared the following recommendations for medical personnel, who participate in the care of this special group of patients in the different clinical settings, who suffer or not, of COVID-19.

ABSTRACT

ABSTRACT Objective To evaluate the nutritional risk factors in patients eligible for hematopoietic stem cell transplantation. Methods A cross-sectional, descriptive study conducted with patients recruited from an hematology outpatient clinic. Study variables included demographic and clinical data, patient-generated global subjective assessment findings, anthropometric indicators, food intake and oxidative stress levels. The level of significance was set at 5% (p<0.05). Results The sample comprised 72 patients, mean age of 48.93 years (14.5%). Multiple myeloma was the most prevalent condition (51.4%) in this sample. Most patients (55.6%) were overweight according to body mass index and at risk of cardiovascular disease according to waist circumference, conicity index and percentage of body fat. Sarcopenia was associated with risk of cardiovascular disease, hip-to-waist ratio (p=0.021), muscle strength depletion (p<0.001), food intake (p=0.023), reduced functional capacity (p=0.048), self-reported well-nourished status; p=0.044) and inadequate vitamin B6 (p=0.022) and manganese (p=0.026) intake. Elevated oxidative stress, detected in 33.3% of patients in this sample, was not associated with sarcopenia. Conclusion Most patients in this sample were overweight and sarcopenic. Lean mass depletion was associated with risk of cardiovascular disease, reduced muscle strength, food intake changes, reduced functional capacity, self-reported well-nourished status and inadequate intake of vitamin B6 and manganese, but not with oxidative stress.


RESUMO Objetivo Avaliar os fatores de riscos nutricionais em pacientes pré-transplante de célula-tronco hematopoiética. Métodos Estudo transversal, descritivo, realizado com pacientes de um ambulatório de hematologia. As variáveis estudadas foram demográficas, dados clínicos, avaliação subjetiva global produzida pelo próprio paciente, indicadores antropométricos, ingestão alimentar e estresse oxidativo. Os dados foram considerados estatisticamente significativos quando p<0,05. Resultados A amostra do estudo foi constituída por 72 pacientes, com média de idade de 48,93 (14,5%) anos e com mieloma múltiplo (51,4%) como a patologia mais prevalente. Conforme índice de massa corporal, 55,6% dos pacientes encontravam-se com excesso de peso. De acordo com a circunferência da cintura, índice de conicidade e percentual de gordura corporal, houve prevalência de risco para doença cardiovascular. A sarcopenia foi associada ao risco de doença cardiovascular pela relação cintura/quadril (p=0,021), depleção da força muscular (p<0,001), além da ingestão alimentar (p=0,023), da capacidade funcional reduzida (p=0,048) e do diagnóstico de "bem nutrido" (p=0,044), conforme a avaliação subjetiva global, e com consumo inadequado de vitamina B6 (p=0,022) e de manganês (p=0,026). Dentre os avaliados, 33,3% apresentaram estresse oxidativo elevado sem associação com sarcopenia. Conclusão Pacientes do pré-transplante se apresentam, em sua maioria, com excesso de peso, mas com sarcopenia, estando essa ausência de massa magra associada a risco de doença cardiovascular, depleção da força muscular, alteração da ingestão alimentar, redução da capacidade funcional, classificação de "bem nutrido", segundo a avaliação subjetiva global e consumo inadequado de vitamina B6 e manganês, não estando associada a estresse oxidativo.

ABSTRACT

ABSTRACT The coronavirus disease 2019 (covid-19) pandemic has caused a public health emergency worldwide. Risk, severity and mortality of the disease have been associated with non-communicable chronic diseases, such as diabetes mellitus. Accumulated evidence has caused great concern in countries with high prevalence of this morbidity, such as Brazil. This text shows the picture of diabetes in Brazil, followed by epidemiological data and explanatory hypothesis for the association between diabetes and covid-19. We emphasized how the burden of these two morbidities in a middle-income country has aggravated this pandemic scenario. The comprehension of this association and biological plausibility may help face this pandemic and future challenges.

ABSTRACT

Abstract: Gingivitis and periodontitis are associated with a negative impact on Oral Health Related Quality of Life (OHRQoL), exerting a significant influence on aspects related to the patients' function and esthetics. Periodontitis has been associated with several systemic conditions, including adverse pregnancy outcomes, cardiovascular diseases, type 2 diabetes mellitus (DM), respiratory disorders, fatal pneumonia in hemodialysis patients, chronic renal disease and metabolic syndrome. The aim of this paper was to review the results of different periodontal treatments and their impacts on patients' OHRQoL and systemic health. Non-surgical and surgical periodontal treatments are predictable procedures in terms of controlling infection, reducing probing pocket depth and gaining clinical attachment. In addition, the treatment of periodontitis may significantly improve OHRQoL and promote a reduction in the levels of systemic markers of inflammation, including some cytokines associated with cardiovascular diseases. Studies have also suggested that periodontal treatment may improve glycemic control in patients with DM. Strategies and actions for preventing the onset and recurrence of periodontitis, and the challenges facing the field of periodontology in the XXI century are presented in this review.

ABSTRACT

Microbial translocation is associated with the increased risk of cardiovascular disease in HIV-infected individuals. There is scarce information regarding the possible associations between the biomarkers of microbial translocation, inflammation and cardiovascular risk that can be evaluated in clinical laboratories using plasma or serum samples. This systematic review was conducted according to the PRISMA protocol in order to verify the most used soluble biomarkers of microbial translocation, inflammation and cardiovascular risk, as well as possible associations between them, in HIV-infected individuals. A search was performed using the Medline, Scopus and Web of Science databases to identify existing studies regarding the relationship between microbial translocation biomarkers, inflammation and cardiovascular risk in HIV-infected patients. Eleven articles that presented soluble biomarkers of microbial translocation (LPS, rDNA, sCD14, LBP and EndoCAb) were selected. The most frequently evaluated soluble biomarker was sCD14, followed by LPS; the latter were associated with some lipid profile parameters. This systematic review considered soluble blood biomarkers that can be utilized in laboratory diagnosis. The aim was to identify the interconnection between microbial translocation, inflammation and cardiovascular risk. Despite the fact that a large number of inflammation and cardiovascular risk biomarkers have been previously reported, it was noted that important markers involved in the pathophysiology of cardiovascular diseases need to be included in future research.

ABSTRACT

La importancia de la nutrición en modificar el riesgo de enfermedad cardiovascular aterosclerótica (ECVA) se ha enfatizado repetidas veces. Históricamente, el papel de los componentes dietarios ha sido el foco predominante; sin embargo, los alimentos, típicamente, se consumen en combinación más que aisladamente. En los últimos años, se ha puesto una mayor atención a los patrones dietarios y su relación con eventos clínicos del tipo de la ECVA, diabetes mellitus tipo 2 y obesidad; paradójicamente, existe una brecha en la educación nutricional en las escuelas de medicina de todo el mundo. Por lo general, una dieta no saludable está asociada con alteraciones cardiometabólicas, una condición clínica que, gradualmente, puede empeorar y conducir a diversos factores comunes de riesgo de enfermedades crónicas, a mayor morbilidad y mortalidad y menoscabo en la calidad de vida. El público en general debe satisfacer la cantidad de calorías requeridas con una variedad de alimentos densos en nutrientes que abarquen todos los grupos de alimentos para mantener la salud a largo plazo. El estilo de patrones saludables de comer varía individualmente y frecuentemente refleja las preferencias culturales y personales. Una alimentación no saludable puede causar una elevación de la producción posprandial de insulina e hipersecreción crónica de insulina e hiperinsulinemia, lo cual promueve la acumulación de grasa, previene la lipólisis y causa incremento en el riesgo de desarrollar ECVA, obesidad y diabetes tipo(AU)


The importance of nutrition in modifying the risk of atherosclerotic cardiovascular disease (ACVD) has been repeatedly emphasized. Historically, the role of dietary components has been the predominant focus; however, foods are typically consumed in combinations rather than individually. Over the last few years, increasing attention has been given to dietary patterns and their relationship to clinical events such as ACVD, type 2 diabetes and obesity; paradoxically, there is a gap in nutrition education in medical school around the globe. An unhealthy diet is usually associated with cardiometabolic alterations, a clinical situation that can progressively worse, potentially leading to various common risk factors, increased morbidity and mortality, and reduced quality of life. People should aim to fulfill their recommended calorie intake with a variety of nutrient-dense foods that span all food groups to boost long-term health. Healthy eating styles may vary from individual to individual and frequently reflect cultural and personal preferences. An unhealthy diet may cause a high postprandial insulin production and chronic insulin hypersecretion and hyperinsulinemia, which promote fat storage, prevent lipolysis and cause increased the risk for developing ACVD, obesity and type 2 diabetes

ABSTRACT

Se realizó una investigación cuantitativa de tipo correlacional con el objeto de evaluar la asociación entre microalbuminuria (MA), proteína C reactiva ultrasensible (PCR-us) y riesgo cardiovascular (RCV) de acuerdo a la escala de Framingham en pacientes con síndrome metabólico (SM) que asistieron a la consulta del Servicio de Medicina Interna del Hospital Universitario Dr. Luis Gómez López durante el período junio 2017-junio 2018. La muestra la conformaron 30 pacientes con una edad promedio de 49,53 ± 13,35 años y predominio del sexo femenino. El 53,3% de los pacientes no tenía tratamiento. El 73,3% de los pacientes presentaron RCV muy alto y alto de acuerdo a la escala de Framingham. La mayor parte de los pacientes con RCV muy alto presentaron valores elevados de PCR-us. Se observó una correlación positiva entre los valores de PCR-us y el RCV (R=0,533, p < 0.05). Es importante la identificación temprana del SM como factor de riesgo para el desarrollo de enfermedades cardiovasculares(AU)


A correlation-type quantitative investigation was carried out with the aim to evaluate the association between microalbuminuria (MA), high-sensitive C-reactive protein (hs-CRP) and cardiovascular risk (CVR) determined by the Framingham scale in patients with Metabolic Syndrome (MS) who attended the Internal Medicine Service of the Hospital Universitario Dr. Luis Gómez López during the period June 2017-June 2018. Thirty patients were included with an average age of 49.53 ± 13.35 years and female sex predominance. According to the Framingham scale, 73.3% of patients had very high and high CVR. Most patients with very high CVR had elevated levels of hs-CRP. There was a positive and significant correlation between hs-CRP levels and CVR (R=0.533, p <0.05). An early diagnosis of MS is important as a risk factor for the development of cardiovascular disease(AU)

ABSTRACT

abstract Objective: Oral antiplatelet drugs are a key to modern pharmacotherapy in cardiovascular atherothrombotic diseases. Clopidogrel (CLO) constitutes the main preventive treatment of atherothrombosis. However, a considerable inter-individual variation in CLO response has been documented, resulting in suboptimal therapy and an increased risk of recurrent adverse effects in some patients. The enzyme CYP2C19 has been reported to be the CYP isoform that activates CLO to its active metabolite. Several single nucleotide polymorphisms in the CYP2C19 gene have been identified as strong predictors of CLO-impaired pharmacological response. At least 16 variants have been associated with changes in CYP2C19 activity. Materials and Methods: The following research was composed of a total of 102 subjects with high cardiovascular risk in the northeast of Mexico, with a maintenance dose of 75 mg of CLO per day. The platelet reactivity was measured with VerifyNow P2Y12 assay, while the presence of CYP2C19*2 was identified by real-time polymerase chain reaction. Results: Patients were categorized by CYP2C19 metabolizer status based on *2 genotypes using the common consensus star allele nomenclature as normal metabolizer (G/G), intermediate metabolizer (G/A), and poor metabolizer (A/A), respectively. The phenotype frequency for CYP2C19*2 was 74.5% (G/G), 21.6% (G/A), and 3.9% (A/A). The subjects with the A allele presented ≥235 P2Y12 reaction unit levels, classifying them how poor metabolizer. The prevalence of reduced CLO effectiveness was associated with the presence of CYP2C19*2 polymorphism among Mexican patients. Conclusion: The presence of the CYP2C19*2 allele is related to resistance to the antiplatelet effect of CLO (p = 0.003).


Resumen Objetivo: Los antiplaquetarios orales son clave en la farmacoterapia moderna de las enfermedades aterotrombóticas cardiovasculares. Clopidogrel (CLO) constituye el principal tratamiento preventivo de aterotrombosis (AT). Sin embargo, se ha documentado una considerable variación interindividual en la respuesta a CLO, lo que da como resultado una terapia subóptima y mayor riesgo de efectos adversos en algunos pacientes. La enzima CYP2C19 es la isoforma CYP que activa CLO a su metabolito activo. Se han identificado varios polimorfismos de un solo nucleótido en el gen CYP2C19 como fuertes predictores de respuesta farmacológica alterada a CLO. Al menos 16 variantes se han asociado con cambios en la actividad de CYP2C19. Método: Se reclutaron un total de 102 sujetos con alto riesgo cardiovascular del noreste de México, con dosis de mantenimiento de 75 mg de CLO/día. La reactividad plaquetaria se midió con el ensayo Verify Now P2Y12, la presencia de CYP2C19*2 se identificó mediante polymerase chain reaction en tiempo real. Resultado: Los pacientes fueron clasificados por el estado metabolizador CYP2C19*2 utilizando nomenclatura consenso, como metabolizador normal (G/G), metabolizador intermedio (G/A) y metabolizador pobre (A/A), respectivamente. La frecuencia del fenotipo para CYP2C19*2 fue 74.5% (G/G), 21.6% (G/A) y 3.9% (A/A). Los sujetos con alelo A presentaron ≥235 niveles P2Y12 reaction unit, clasificándolos como metabolizadores deficientes. La prevalencia de eficacia reducida a CLO se asoció con la presencia del polimorfismo CYP2C19*2 en pacientes mexicanos. Conclusiones: La presencia del alelo CYP2C19*2 se relaciona con resistencia al efecto antiagregante plaquetario del CLO (p = 0.003).

ABSTRACT

Patients with mental disorders are more susceptible to cardiovascular diseases and metabolic disorders compared to the general population. Objective: To evaluate cardiovascular risk and metabolic syndrome in individuals with mental disorders. Materials and methods: A cross-sectional study, conducted at the Psychosocial Care Centers. Socioeconomic, clinical, biochemical and anthropometric data were collected using a standard form. Cardiovascular risk was assessed by the Framingham risk score. Metabolic syndrome (MS) was determined by the World Health- Organization (WHO), the National Cholesterol Education Program (NCEP) and the International Diabetes Federation (IDF) criteria. Data were analyzed by descriptive statistics, and associations were evaluated by the chi-square test and Fisher's exact test, as well as Odds Ratio. The significance level adopted for all statistical tests was 5%. Results: The chance of individuals diagnosed with MS be at intermediate-to-high cardiovascular risk was greater (12.22, 8.01 and 6.23 times higher according to WHO, NCEP and IDF criteria, respectively) than those without MS. Conclusion: A high percentage of patients with mental disorders were at intermediate / high cardiovascular risk, and this was significantly associated with MS

ABSTRACT

Resumen Los pacientes que sufren una enfermedad cardiovascular requieren de atención médica integral que involucre las terapias y procedimientos necesarios para reintegrarlos de forma óptima a su vida personal, familiar, laboral y social. Las intervenciones dirigidas a alcanzar dichas metas se incluyen en los programas de rehabilitación cardiaca. Estos programas son diseáados para limitar los efectos dañinos tanto fisiológicos como psicológicos de las cardiopatías, reducir el riesgo de muerte súbita o reinfarto, controlar la sintomatología cardiovascular, estabilizar o revertir el proceso de aterosclerosis y mejorar el estado psicosocial y vocacional de los pacientes. Dichos programas existen en México desde la década de 1940 y han evolucionado a lo largo de los años, adaptándose a las condiciones de enfermedad presentes en nuestro país, desde su inicio con terapias para tratar a pacientes cardiopatía reumática hasta la aplicación del ejercicio físico en pacientes con insuficiencia cardiaca, cardiopatías congénitas complejas o hipertensión arterial pulmonar. Estas actividades son de índole transdisciplinaria e implica la integración de cardiólogos, fisioterapeutas, psicólogos y nutriólogos, entre otros. Actualmente, estos programas se han extendido a lo largo de la República Mexicana gracias a cardiólogos rehabilitadores egresados de las principales instituciones de salud del país, como son los Institutos de Salud, el IMSS (Instituto Mexicano del Seguro Social) y el ISSSTE (Instituto de Seguridad y Servicios Sociales para los Trabajadores del Estado). En este documento se expondrán los orígenes de la rehabilitación, desde la época prehispánica hasta la actual, destacando las contribuciones en docencia e investigación de los médicos que han ejercido en esta área en las instituciones previamente mencionadas.


Abstract Patients suffering from cardiovascular disease require comprehensive medical attention that involves therapies and procedures necessary to reintegrate them optimally to their personal, family, work and social life. Interventions aimed at achieving these goals are included in cardiac rehabilitation programs. These programs are designed to limit the harmful physiological and psychological effects of heart disease, reduce the risk of sudden death or reinfarction, control cardiovascular symptoms, stabilize or reverse the atherosclerosis process and improve the psychosocial and vocational status of patients. These programs have existed in Mexico since the 1940's and have evolved over the years, adapting to the disease conditions present in our country, starting with therapies to treat patients with rheumatic heart disease until the application of physical exercise in patients with heart failure, complex congenital heart disease or pulmonary arterial hypertension. These activities are of a transdisciplinary nature and involve the integration of cardiologists, physiotherapists, psychologists, and nutritionists among others. Currently, these programs have spread throughout the Mexican Republic thanks to rehabilitation cardiologists graduating from the main health institutions in the country such as Health Institutes, Mexican Social Security Institute and Institute of Security and Social Services of State Workers. In this document, the origins of rehabilitation from the pre-Hispanic era to the present will be discussed, highlighting the contributions in teaching and research of the physicians who have practiced in this area in the aforementioned institutions.

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. As comparações de variáveis numéricas entre grupos foram realizadas por teste t-Student e Wilcoxon Mann-Whitney para amostras independentes, adotando-se o nível de significância de 5%. Resultados: Os pacientes psoriásicos apresentaram aumento de VOP (9,1 ± 1,8 e 8 ± 2 m/s, p = 0,033), EMI da artéria carótida comum esquerda (p = 0,018) e maior proporção de percentil > 75 pela tabela ELSA (54,5 e 18,2%, p = 0,045) e) quando comparados aos controles. Pacientes psoriásicos também mostraram aumento nos seguintes parâmetros em relação ao grupo controle, respectivamente: pressão arterial sistólica periférica/central (137,1 ± 13,2 e 122,3 ± 11,6 mmHg, p = 0,004)/(127 ± 13 e 112,5 ± 10,4 mmHg, p = 0,005), pressão arterial diastólica periférica/central (89,9 ± 8,9 e 82,2 ± 8 mmHg, p = 0,022) / (91 ± 9,3 e 82,2 ± 8,3 mmHg, p = 0,014), colesterol total (252 ± 43,5 e 198 ± 39,8 mg/dL, p < 0,001), colesterol LDL (167 ± 24 e 118 ± 40,8 mg/dL, p < 0,001) e proteína C reativa (7,6 ± 35,4 e 1 ± 1,2 mg/L, p<0,001). Conclusão: Pacientes psoriásicos apresentam elevações de VOP e EMI, além de maiores pressões arteriais periféricas e centrais, níveis séricos de colesterol e de proteína C reativa, denotando maior risco cardiovascular.

ABSTRACT

ABSTRACT Objective The aim of this study is to evaluate and compare arterial stiffness, which is an independent risk indicator for cardiovascular diseases (CVDs), between patients with overt hyperthyroidism, subclinical hyperthyroidism, euthyroidism by antithyroid therapy and healthy volunteers with pulse wave analysis (PWA). Subjects and methods A total of 102 volunteers were included in the study (30 in the overt hyperthyroid group, 28 in the subclinical hyperthyroid group and 14 with euthyroidism by antithyroid therapy and 30 healthy). The arterial stiffness measurements of the participants in the study were performed with the Mobil-O-Graph PWA device (I.E.M. GmBH, Stolberg, Germany), which makes cuff based oscillometric measurement from the brachial artery. Results Systolic blood pressure, pulse rate, central systolic blood pressure, cardiac output, heart rate-corrected augmentation index (Aix@75) and pulse wave velocity (PWV) measurements were significantly higher in the hyperthyroid group than in the control group. The heart rate and PWV in the subclinical hyperthyroid group were significantly higher than the control group. In the euthyroid group, systolic blood pressure, central systolic blood pressure, cardiac output, cardiac index and PWV were found significantly higher than the control group. There was also a negative correlation between Aix@75 and thyroid-stimulating hormone (TSH), and a positive correlation between Aix@75 and free thyroid hormones. Conclusion In our study, we observed that the arterial stiffness was adversely affected by an overt or subclinical increase in thyroid hormones and this correlated with thyroid hormone levels. We recommend that PWV measurement, which is a simple method for detecting CVD risk, can be used in these patients.

ABSTRACT

ABSTRACT Objective: To verify if there is an association between cardiometabolic risk factors and active daily commuting to school among children and adolescents. Methods: A total of 1,743 schoolchildren aged 7 to 17 years old were evaluated in the city of Santa Cruz do Sul (RS). The way of commuting to school was investigated with a questionnaire, and the cardiometabolic risk factors analyzed were body mass index (BMI), waist circumference (WC), systolic (SBP) and diastolic (DBP) blood pressure, blood glucose, triglycerides, total cholesterol (TC) and fractions, LDL and HDL. Results: The prevalence of active commuting among schoolchildren was 48.0% (95%CI 45.7-50.4), and it was associated, in the crude analysis, with blood glucose and LDL cholesterol levels. Passive schoolchildren had a 1.1 higher prevalence ratio of high glucose and LDL cholesterol levels. However, when sociodemographic variables were included in the model, these associations were not maintained. Conclusions: The prevalence of active commuting in the sample studied is low and it was shown to have a crude association with glucose and LDL cholesterol levels in students. However, sociodemographic factors seem to influence these associations.


RESUMO Objetivo: Verificar se existe associação entre fatores de risco cardiometabólicos e deslocamento ativo à escola em crianças e adolescentes. Métodos: Foram avaliados 1.743 escolares, de sete a 17 anos, do município de Santa Cruz do Sul (RS). A forma de deslocamento até a escola foi investigada por meio de questionário e os fatores de risco cardiometabólicos analisados foram: o índice de massa corpórea (IMC), a circunferência da cintura (CC), a pressão arterial sistólica (PAS) e a diastólica (PAD), glicose, triglicerídeos, colesterol total (CT), LDL e HDL. Resultados: A prevalência de deslocamento ativo entre os escolares foi de 48,0% (IC95% 45,7-50,4) e associou-se, na análise bruta, com os níveis de glicose e colesterol LDL. Escolares que se deslocavam de forma passiva apresentaram uma razão de prevalência (RP) 1,1 vez maior de glicose e colesterol LDL elevados. No entanto, ao serem incluídas variáveis sociodemográficas no modelo, essas associações não se mantiveram. Conclusões: Conclui-se que a prevalência de deslocamento ativo na amostra estudada é baixa e que o deslocamento ativo à escola apresentou associação bruta com os níveis sanguíneos de glicose e de colesterol LDL dos escolares, sendo que se deslocar de forma ativa parece auxiliar na redução desses níveis. Porém, fatores sociodemográficos parecem exercer influência sobre estas associações.

ABSTRACT

Resumen Introducción: Previamente se desarrolló una nueva metodología de ayuda diagnóstica para los registros Holter fundamentada en los sistemas dinámicos y la teoría de probabilidad, a partir de la información registrada en 21 horas. Objetivo: Evaluar la capacidad diagnóstica de esta metodología durante 19 horas, comparándola con los resultados convencionales del Holter y con los resultados del método matemático aplicado en 21 horas. Materiales y Métodos: fueron evaluados 80 casos de pacientes mayores a 20 años, 10 con registro Holter normal y 70 diagnosticados de forma convencional con diferentes patologías cardíacas. Se establecieron los rangos para las frecuencias cardíacas y de número de latidos por hora en 21 y 19 horas; luego, se calculó la probabilidad de ocurrencia de estos, lo que permitió diferenciar estados de normalidad y enfermedad aguda a partir de tres parámetros. Se comparó el diagnóstico físico-matemático con el diagnóstico convencional, tomado como Gold Standard. Resultados: De los casos normales, dos presentaron probabilidad menor o igual a 0,217 y ocho probabilidades mayores o igual a 0,304; ningún caso de enfermedad aguda presentó valores con probabilidad menor o igual a 0,217, mientras que todos presentaron valores mayores o iguales a 0,304, tanto para los registros Holter evaluados en 21 como en 19 horas. Conclusiones: Se confirmó la utilidad clínica de la metodología ante una reducción del tiempo de evaluación a 19 horas, obteniendo diagnósticos objetivos con base en la auto-organización matemática del fenómeno.


Abstract Background: a new method to help evaluate 21-hour holter recordings based on dynamic systems and the theory of probability was previously developed Aim: to evaluate the diagnostic value of this methodology in the analysis of 19 hr compared to conventional holter analysis over a 21-hr recording. Methods: the holter recordings of 80 subjects aged over 20 years old were analyzed. Ten subjects had a normal holter and 70 conventionally diagnosed as abnormal. Ranges for heart rate and number of beats in 21 or 19 hours were determined. The probability of their occurrence was calculated using 3 parameters. The mathematically derived diagnosis was compared to the clinical diagnosis, considered a gold standard. Results: Among normal cases the calculated probability was ≤ 0.217 in 2 cases and ≥0.304 in 8. No case with acute disease presented probability values ≤0.217; all had probability values ≥0.304, both in 21 and 19 hour recordings. Conclusion: the mathematical methodology described was clinically useful allowing a reduction in recording time from 21 to 19 hr. Clinical diagnosis may be inferred from the mathematical organization of a holter recording.

ABSTRACT

Background: Coronary artery bypass grafting (CABG) is a type of surgery where there is a compromise in one or more coronary arteries, with the objective of restoring function to the areas that have been compromised in the heart, possibly leading to respiratory compromise and postoperative complications. The return time of the pulmonary function to the preoperative condition is still indeterminate in the literature. Objective: To describe the behavior of pulmonary function after hospital discharge in patients submitted to CABG. Methods: This is a prospective cohort study. Only patients undergoing MRI, whose lung function was evaluated preoperatively, at hospital discharge and 30 days after surgery, were evaluated. This evaluation consisted of maximum inspiratory pressure (MIP) and expiratory (MEP), vital capacity (VC) and expiratory flow peak (EFP). Results: A total of 30 patients were evaluated, of which 18 (60%) were males, mean age 62 ± 9 years. A reduction in lung function from preoperative time to hospital discharge was observed in all variables. There was improvement in MIP (88 ± 9 vs 109 ± 5, p < 0.001), MEP (67 ± 10 for 90 ± 8, p < 0.001) and EFP (310 ± 59 for 390 ± 32, p < 0.001), high for review. At the time of the review, no variables returned to their preoperative value: MIP (116 ± 5 for 109 ± 5, p = 0.43), MEP (111 ± 8 for 90 ± 8, p < 0.001), VC (45 ± 12 for 39 ± 7, p = 0.33) and EFP (430 ± 40 for 390 ± 32, p < 0.001). Conclusion: It is concluded that MRI surgery reduces lung function and is not reestablished after 30 days of the procedure. Being the expiratory muscular force and the peak of expiratory flow the most affected

ABSTRACT

Los incendios forestales representan un problema creciente de la salud pública a nivel mundial, especialmente para la población más vulnerable (niños, ancianos, embarazadas y portadores de enfermedades cardiovasculares o respiratorias crónicas) expuesta al humo y a otros contaminantes aéreos. A diferencia de la contaminación atmosférica habitual de grandes urbes, aquella derivada de los incendios forestales tiene una composición diferente y su ocurrencia es esporádica y difícil de prever. La exposición a contaminantes atmosféricos derivados de incendios forestales se asocia a aumento de la morbilidad respiratoria y cardiovascular, mediada por una respuesta inflamatoria pulmonar y sistémica, estrés oxidativo y disfunción endotelial. En sujetos expuestos a humo de incendios forestales se ha observado un aumento en la producción de citoquinas pro-inflamatorias, activación endotelial y disfunción del sistema nervioso autónomo, que produce daño tisular, aumento de los mecanismos protrombóticos, aumento de la presión arterial y cambios en el ritmo cardiaco. Esta revisión analiza los mecanismos que han sido involucrados en generar efectos nocivos para la salud de seres humanos expuestos a material particulado y gases emanados de incendios forestales.


Wildfires represent a growing global public health issue, especially to the most vulnerable segment of the population (children, old people, pregnant women, patients with cardiovascular or respiratory diseases) exposed to smoke and other air borne contaminants generated from these events. In contrast to great cities ' usual atmospheric pollution, that derives from forest fires differ in composition and its occurrence is sporadic and usually unpredictable. Exposure to atmospheric pollutants derived from forest fires has been associated to increased respiratory and cardiovascular morbidity, mediated by an inflammatory systemic response, oxidative stress and endothelial dysfunction. In people exposed to forest fire smoke an increased production of pro-inflammatory cytokines, endothelial activation and autonomic nervous system dysfunction has been observed, that leads to tissue injury, increased prothrombotic response, increased blood pressure and changes in heart rhythm. This review analyzes the mechanisms that have been involved in generating harmful health effects in humans exposed to inhaled particulate matter and gases steaming from wildfires.
