Intracranial pressure waveform in patients with essential hypertension.

Background: There is a strong association between hypertension and cerebrovascular diseases, but most of the mechanistic bases to justify this correlation remains misunderstood. Objective: To evaluate intracranial pressure waveform in long-term essential hypertensive patients with a non-invasive device, brain4care (b4c). Methods: Cross-sectional study in patients with hypertension. Office blood pressure was measured with an automatic oscillometric device. Intracranial pressure evaluation was acquired through a strain sensor that could detect and monitor nanometric skull bone displacements for each cardiac cycle. Under normal physiological conditions, P1 is greater than P2, and the normal P2/P1 ratio is <1. Time to peak (TTP) is the measurement in seconds of the beginning of waveform inscription until P1 and normal values are <0.20 s. The cut-off points ≥1.2 and ≥0.25 s were used to define intracranial hypertension (ICHT). Results: 391 consecutive patients were evaluated (75% female, mean age 64.3 ± 12.0 years). Mean value of P2/P1 ratio was 1.18 ± 0.25 and TTP 0.18 ± 0.63 s The obtained P2/P1 ratios were divided in three categories according to results of previous studies of normalcy (<1.0), intracranial compliance disturbance (1.0-1.19) and ICHT (≥1.2). Normal intracranial pressure was observed in 21.7% of patients, intracranial compliance disturbance in 32.7% and intracranial hypertension in 45.6%. Females showed a higher prevalence of ICHT (50.3%). Conclusion: The prevalence of 45.6% intra-cranial hypertension in patients with long-term hypertension, particularly in women, and in those over 65 years old, emphasizes the importance of evaluate intracranial pressure behaviour in these patients and raise a question concerning the real ability of cerebral autoregulation and vascular barriers to protect the brain.

Pulse Wave Velocity of 8.2 m/s as a Threshold Associated with Cardiovascular Target Organ Damage Presence. / Velocidade de Onda de Pulso de 8,2m/s como Limiar Associado à Presença de Lesão de Órgão Alvo Cardiovascular.

BACKGROUND: Previous studies have established normal and reference values for Pulse Wave Velocity (PWV). However, the PWV value that has the strongest association with cardiovascular biomarkers remains poorly understood. OBJECTIVE: This study aimed to determine the PWV value more likely to be associated with left ventricular hypertrophy (LVH), increased intima-media thickness (IMT), and presence of carotid plaques in patients with hypertension. METHODS: This cross-sectional study included 119 patients. Analysis of receiver operating characteristic (ROC) curves was performed for each cardiovascular biomarker. Statistical significance was set at p < 0.05. RESULTS: According to the ROC curve analysis, the PWV values were 8.1 m/s, 8.2 m/s, and 8.7 for the LVH, IMT, and presence of carotid plaques, respectively. A PWV value of 8.2 m/s was identified as the best parameter to determine the three TOD biomarkers. PWV above 8.2 m/s was associated with increased CIMT (p = 0.004) and the presence of carotid plaques (p = 0.003) and LVH (p<0.001). PWV above 8.2 showed greater sensitivity for increased CIMT (AUC = 0.678, sensitivity = 62.2), LVH (AUC = 0.717, sensitivity = 87.2), and the presence of plaques (AUC = 0.649, sensitivity = 74.51) in the ROC curve analysis. CONCLUSION: The PWV value 8.2 m/s was more sensitive in early identifying the existence of cardiovascular biomarkers of TOD.

FUNDAMENTO: Estudos prévios estabeleceram valores de normalidade e de referência da Velocidade de Onda de Pulso (VOP). Porém, qual valor de VOP que apresenta a associação mais forte com biomarcadores cardiovasculares ainda é pouco conhecido. OBJETIVO: Identificar o valor de VOP com maior possibilidade de estar associado com hipertrofia ventricular esquerda (HVE), aumento da espessura íntima-média carotídea (EIMC), e presença de placas carotídeas em pacientes hipertensos. MÉTODOS: Este é um estudo transversal de 119 pacientes. Análise de curvas características de operação do receptor (ROC) foi realizada para cada biomarcador cardiovascular. A diferença estatística foi estabelecida em p<0,05. RESULTADOS: Segundo análises das curvas ROC, valores de VOP de 8,1m/s para HVE, 8,2m/s para EMIC aumentada e 8,7m/s para a presença de placa carotídea foram encontrados, respectivamente. O valor de VOP de 8,2m/s foi definido como melhor o parâmetro para encontrar os três biomarcadores de LOA. A VOP acima de 8,2m/s associou-se ao aumento da EMIC (p = 0,004), à presença de placas carotídeas (p = 0,003) e à HVE (p < 0,001). A VOP acima de 8,2m/s apresentou maior sensibilidade para EMIC aumentada (AUC = 0,678, sensibilidade 62,2), HVE (AUC = 0,717, sensibilidade 87,2), e presença de placas (AUC = 0,649, sensibilidade 74,51) na análise das curvas ROC. CONCLUSÃO: O valor de 8,2m/s de VOP foi mais sensível em identificar, precocemente, a existência de biomarcadores cardiovasculares de LOA.

Hypertension evaluated in the public and private Brazilian health system hypertension in public and private service.

Introduction: Hypertension (HT) remains the leading cause of death worldwide. In Brazil it is estimated that 35% of the adult population has HT and that about 20% of these have blood pressure values within the targets recommended for the reduction of cardiovascular risk. There are some data that point to different control rates in patients treated by cardiologists in public and private referral center and this is an important point to be investigated and discussed. Objective: To compare sociodemographic characteristics, body mass index (BMI), antihypertensive (AH) drugs, blood pressure (BP) and control rate in public (PURC) and private (PRRC) referral centers. Methodology: A cross-sectional multicenter study that analyzed data from hypertensive patients assisted by the PURC (one in Midwest Region and other in Northeast region) and PRRC (same distribution). Variables analyzed: sex, age, BMI, classes, number of AH used and mean values of systolic and diastolic BP by office measurement and home blood pressure measurement (HBPM). Uncontrolled hypertension (HT) phenotypes and BP control rates were assessed. Descriptive statistics and χ2 tests or unpaired t-tests were performed. A significance level of p < 0.05 was considered. Results: A predominantly female (58.9%) sample of 2.956 patients and a higher prevalence of obesity in PURC (p < 0.001) and overweight in PRRC (p < 0.001). The mean AH used was 2.9 ± 1.5 for PURC and 1.4 ± 0.7 for PRRC (p < 0.001). Mean systolic and diastolic BP values were higher in PURC as were rates of uncontrolled HT of 67.8% and 47.6% (p < 0.001) by office measurement and 60.4% and 35.3% (p < 0.001) by HBPM in PURC and PRRC, respectively. Conclusion: Patients with HT had a higher prevalence of obesity in the PURC and used almost twice as many AH drugs. BP control rates are worse in the PURC, on average 15.3 mmHg and 12.1 mmHg higher than in the PRRC by office measurement.

Brazilian Guidelines for In-office and Out-of-office Blood Pressure Measurement ­ 2023 / Diretrizes Brasileiras de Medidas da Pressão Arterial Dentro e Fora do Consultório ­ 2023

Hypertension is one of the primary modifiable risk factors for morbidity and mortality worldwide, being a major risk factor for coronary artery disease, stroke, and kidney failure. Furthermore, it is highly prevalent, affecting more than one-third of the global population. Blood pressure measurement is a MANDATORY procedure in any medical care setting and is carried out by various healthcare professionals. However, it is still commonly performed without the necessary technical care. Since the diagnosis relies on blood pressure measurement, it is clear how important it is to handle the techniques, methods, and equipment used in its execution with care. It should be emphasized that once the diagnosis is made, all short-term, medium-term, and long-term investigations and treatments are based on the results of blood pressure measurement. Therefore, improper techniques and/or equipment can lead to incorrect diagnoses, either underestimating or overestimating values, resulting in inappropriate actions and significant health and economic losses for individuals and nations. Once the correct diagnosis is made, as knowledge of the importance of proper treatment advances, with the adoption of more detailed normal values and careful treatment objectives towards achieving stricter blood pressure goals, the importance of precision in blood pressure measurement is also reinforced. Blood pressure measurement (described below) is usually performed using the traditional method, the so-called casual or office measurement. Over time, alternatives have been added to it, through the use of semi-automatic or automatic devices by the patients themselves, in waiting rooms or outside the office, in their own homes, or in public spaces. A step further was taken with the use of semi-automatic devices equipped with memory that allow sequential measurements outside the office (ABPM; or HBPM) and other automatic devices that allow programmed measurements over longer periods (HBPM). Some aspects of blood pressure measurement can interfere with obtaining reliable results and, consequently, cause harm in decision-making. These include the importance of using average values, the variation in blood pressure during the day, and short-term variability. These aspects have encouraged the performance of a greater number of measurements in various situations, and different guidelines have advocated the use of equipment that promotes these actions. Devices that perform HBPM or ABPM, which, in addition to allowing greater precision, when used together, detect white coat hypertension (WCH), masked hypertension (MH), sleep blood pressure alterations, and resistant hypertension (RHT) (defined in Chapter 2 of this guideline), are gaining more and more importance. Taking these details into account, we must emphasize that information related to diagnosis, classification, and goal setting is still based on office blood pressure measurement, and for this reason, all attention must be given to the proper execution of this procedure.

La hipertensión arterial (HTA) es uno de los principales factores de riesgo modificables para la morbilidad y mortalidad en todo el mundo, siendo uno de los mayores factores de riesgo para la enfermedad de las arterias coronarias, el accidente cerebrovascular (ACV) y la insuficiencia renal. Además, es altamente prevalente y afecta a más de un tercio de la población mundial. La medición de la presión arterial (PA) es un procedimiento OBLIGATORIO en cualquier atención médica o realizado por diferentes profesionales de la salud. Sin embargo, todavía se realiza comúnmente sin los cuidados técnicos necesarios. Dado que el diagnóstico se basa en la medición de la PA, es claro el cuidado que debe haber con las técnicas, los métodos y los equipos utilizados en su realización. Debemos enfatizar que una vez realizado el diagnóstico, todas las investigaciones y tratamientos a corto, mediano y largo plazo se basan en los resultados de la medición de la PA. Por lo tanto, las técnicas y/o equipos inadecuados pueden llevar a diagnósticos incorrectos, subestimando o sobreestimando valores y resultando en conductas inadecuadas y pérdidas significativas para la salud y la economía de las personas y las naciones. Una vez realizado el diagnóstico correcto, a medida que avanza el conocimiento sobre la importancia del tratamiento adecuado, con la adopción de valores de normalidad más detallados y objetivos de tratamiento más cuidadosos hacia metas de PA más estrictas, también se refuerza la importancia de la precisión en la medición de la PA. La medición de la PA (descrita a continuación) generalmente se realiza mediante el método tradicional, la llamada medición casual o de consultorio. Con el tiempo, se han agregado alternativas a través del uso de dispositivos semiautomáticos o automáticos por parte del propio paciente, en salas de espera o fuera del consultorio, en su propia residencia o en espacios públicos. Se dio un paso más con el uso de dispositivos semiautomáticos equipados con memoria que permiten mediciones secuenciales fuera del consultorio (AMPA; o MRPA) y otros automáticos que permiten mediciones programadas durante períodos más largos (MAPA). Algunos aspectos en la medición de la PA pueden interferir en la obtención de resultados confiables y, en consecuencia, causar daños en las decisiones a tomar. Estos incluyen la importancia de usar valores promedio, la variación de la PA durante el día y la variabilidad a corto plazo. Estos aspectos han alentado la realización de un mayor número de mediciones en diversas situaciones, y diferentes pautas han abogado por el uso de equipos que promuevan estas acciones. Los dispositivos que realizan MRPA o MAPA, que además de permitir una mayor precisión, cuando se usan juntos, detectan la hipertensión de bata blanca (HBB), la hipertensión enmascarada (HM), las alteraciones de la PA durante el sueño y la hipertensión resistente (HR) (definida en el Capítulo 2 de esta guía), están ganando cada vez más importancia. Teniendo en cuenta estos detalles, debemos enfatizar que la información relacionada con el diagnóstico, la clasificación y el establecimiento de objetivos todavía se basa en la medición de la presión arterial en el consultorio, y por esta razón, se debe prestar toda la atención a la ejecución adecuada de este procedimiento.

A hipertensão arterial (HA) é um dos principais fatores de risco modificáveis para morbidade e mortalidade em todo o mundo, sendo um dos maiores fatores de risco para doença arterial coronária, acidente vascular cerebral (AVC) e insuficiência renal. Além disso, é altamente prevalente e atinge mais de um terço da população mundial. A medida da PA é procedimento OBRIGATÓRIO em qualquer atendimento médico ou realizado por diferentes profissionais de saúde. Contudo, ainda é comumente realizada sem os cuidados técnicos necessários. Como o diagnóstico se baseia na medida da PA, fica claro o cuidado que deve haver com as técnicas, os métodos e os equipamentos utilizados na sua realização. Deve-se reforçar que, feito o diagnóstico, toda a investigação e os tratamentos de curto, médio e longo prazos são feitos com base nos resultados da medida da PA. Assim, técnicas e/ou equipamentos inadequados podem levar a diagnósticos incorretos, tanto subestimando quanto superestimando valores e levando a condutas inadequadas e grandes prejuízos à saúde e à economia das pessoas e das nações. Uma vez feito o diagnóstico correto, na medida em que avança o conhecimento da importância do tratamento adequado, com a adoção de valores de normalidade mais detalhados e com objetivos de tratamento mais cuidadosos no sentido do alcance de metas de PA mais rigorosas, fica também reforçada a importância da precisão na medida da PA. A medida da PA (descrita a seguir) é habitualmente feita pelo método tradicional, a assim chamada medida casual ou de consultório. Ao longo do tempo, foram agregadas alternativas a ela, mediante o uso de equipamentos semiautomáticos ou automáticos pelo próprio paciente, nas salas de espera ou fora do consultório, em sua própria residência ou em espaços públicos. Um passo adiante foi dado com o uso de equipamentos semiautomáticos providos de memória que permitem medidas sequenciais fora do consultório (AMPA; ou MRPA) e outros automáticos que permitem medidas programadas por períodos mais prolongados (MAPA). Alguns aspectos na medida da PA podem interferir na obtenção de resultados fidedignos e, consequentemente, causar prejuízo nas condutas a serem tomadas. Entre eles, estão: a importância de serem utilizados valores médios, a variação da PA durante o dia e a variabilidade a curto prazo. Esses aspectos têm estimulado a realização de maior número de medidas em diversas situações, e as diferentes diretrizes têm preconizado o uso de equipamentos que favoreçam essas ações. Ganham cada vez mais espaço os equipamentos que realizam MRPA ou MAPA, que, além de permitirem maior precisão, se empregados em conjunto, detectam a HA do avental branco (HAB), HA mascarada (HM), alterações da PA no sono e HA resistente (HAR) (definidos no Capítulo 2 desta diretriz). Resguardados esses detalhes, devemos ressaltar que as informações relacionadas a diagnóstico, classificação e estabelecimento de metas ainda são baseadas na medida da PA de consultório e, por esse motivo, toda a atenção deve ser dada à realização desse procedimento.

SAGE Score in Normotensive and Pre-Hypertensive Patients: A Proof of Concept. / Escore SAGE em Normotensos e Pré-Hipertensos: Uma Prova de Conceito.

BACKGROUND: The SAGE score was developed to detect individuals at risk for increased pulse wave velocity (PWV). So far, studies have been focused on hypertensive patients. OBJECTIVE: To assess the ability of the score to detect non-hypertensive and pre-hypertensive patients at risk for increased PWV. METHODS: Retrospective cross-sectional study of analysis of central blood pressure data and calculation of the SAGE score of non-hypertensive and pre-hypertensive patients. Each score point was analyzed for sensitivity, specificity, positive and negative predictive values, using the cut-off point for positive diagnosis a PVW ≥ 10m/s, ≥9.08 m/s (75thpercentile) and ≥7.30 m/s (50thpercentile). A p<0.05 was considered statistically significant. RESULTS: The sample was composed of 100 normotensive and pre-hypertensive individuals, with mean age of 52.64 ± 14.94 years and median PWV of 7.30 m/s (6.03 - 9.08). The SAGE score was correlated with age (r=0.938, p<0.001), glycemia (r=0.366, p<0.001) and glomerular filtration rate (r=-0.658, p<0.001). The area under the ROC curve was 0.968 (p<0.001) for PWV ≥ 10 m/s, 0.977 (p<0.001) for PWV ≥ 9.08 m/s and 0.967 (p<0.001) for PWV ≥ 7.30 m/s. The score 7 showed a specificity of 95.40% and sensitivity of 100% for PWV≥10 m/s. The cut-off point would be of five for a PWV≥9.08 m/s (sensitivity =96.00%, specificity = 94.70%), and two for a PWV ≥ 7.30 m/s. CONCLUSION: The SAGE score could identify individuals at higher risk of arterial stiffness, using different PWV cutoff points. However, the development of a specific score for normotensive and pre-hypertensive subjects is needed.

FUNDAMENTO: O SAGE foi desenvolvido para identificar hipertensos com chance de velocidade de onda de pulso (VOP) aumentada. Até o momento, as publicações do escore foram em hipertensos. OBJETIVO: Verificar a capacidade do SAGE de identificar os normotensos ou pré-hipertensos com chance de aumento da VOP. MÉTODOS: Transversal retrospectivo, incluiu exames de normotensos e pré-hipertensos que realizaram a medida central da pressão arterial e apresentavam os parâmetros para o cálculo do escore. Para cada pontuação do escore, foi analisada a sensibilidade, especificidade, valor preditivo positivo e negativo utilizando como ponto de corte para o diagnóstico positivo VOP ≥ 10m/s, ≥9,08 m/s (percentil 75) e ≥7,30 m/s (percentil 50). Um valor de p<0,05 foi adotado como estatisticamente significante. RESULTADOS: A amostra foi de 100 participantes normotensos ou pré-hipertensos, com média (DP) de 52,64 (14,94) anos e VOP mediana de 7,30 m/s (6,03 ­ 9,08). O SAGE apresentou correlação com idade (r=0,938, p<0,001), glicemia (r=0,366, p<0,001) e taxa de filtração de glomerular (r=-0,658, p<0,001). A área sob a curva ROC foi de 0,968 (p<0,001) para VOP≥10 m/s, 0,977 (p<0,001) para VOP≥9,08 m/s e 0,967 (p<0,001) para VOP≥7,30 m/s. O escore 7 apresentou especificidade de 95,40% e sensibilidade de 100% para VOP≥10 m/s. O ponto de corte seria cinco para VOP≥9,08 m/s (s=96,00%, e= 94,70%), e dois para VOP≥7,30 m/s. CONCLUSÃO: O SAGE foi capaz de identificar indivíduos com maior chance de apresentar rigidez arterial, utilizando diferentes pontos de corte de VOP. Entretanto, o desenvolvimento de um escore específico para normontensos e pré-hipertensos faz-se necessário.

Cardiovascular risk factors in the elderly: a 10-year follow-up survival analysis.

AIMS: Cardiovascular risk factors present a high prevalence and have an impact on the morbimortality of the elderly; however, studies evaluating the impact of cardiovascular risk factors in the elderly have had short follow-up times and have not allowed specific analyses of the effects of these factors in the aged population, including how they affect the survival of the elderly. This study aimed to analyse the survival of elderly individuals living in the community, considering the presence of cardiovascular risk factors. METHODS AND RESULTS: A prospective 10-year follow-up was initiated in 2008 with a cohort of 418 elderly people living in a community in Central Brazil. The Kaplan-Meier method and the Cox proportional hazards model were used to examine the association between survival and cardiovascular risk factors. The mean age of the participants was 70.6 (±7.1) years; most participants were hypertensive (81.6%) and participated in irregular physical activity (44%), and 43.3% smoked. After a mean follow-up of 8.38 (±2.82) years, 59.3% had survived and 34.1% had died; among the deaths, 14.1% were due to cardiovascular causes. Age [hazard ratio (HR) 1.067, 95% confidence interval (CI) 1.027-1.109], hypertension (HR 3.178, 95% CI 1.144-8.826), and smoking (HR 2.235, 95% CI 1.253-3.987) were confirmed as risk factors for reduced survival, whereas physical activity was a protective factor (HR 0.456, 95% CI 0.206-1.007). CONCLUSION: The results from this study highlight the need for educational policies towards hypertension and smoking prevention among elderly people, and participation in physical activity needs to be encouraged.

Identifying multimorbidity clusters among Brazilian older adults using network analysis: Findings and perspectives.

In aging populations, multimorbidity (MM) is a significant challenge for health systems, however there are scarce evidence available in Low- and Middle-Income Countries, particularly in Brazil. A national cross-sectional study was conducted with 11,177 Brazilian older adults to evaluate the occurrence of MM and related clusters in Brazilians aged ≥ 60 years old. MM was assessed by a list of 16 physical and mental morbidities and it was defined considering ≥ 2 morbidities. The frequencies of MM and its associated factors were analyzed. After this initial approach, a network analysis was performed to verify the occurrence of clusters of MM and the network of interactions between coexisting morbidities. The occurrence of MM was 58.6% (95% confidence interval [CI]: 57.0-60.2). Hypertension (50.6%) was the most frequent morbidity and it was present all combinations of morbidities. Network analysis has demonstrated 4 MM clusters: 1) cardiometabolic; 2) respiratory + cancer; 3) musculoskeletal; and 4) a mixed mental illness + other diseases. Depression was the most central morbidity in the model according to nodes' centrality measures (strength, closeness, and betweenness) followed by heart disease, and low back pain. Similarity in male and female networks was observed with a conformation of four clusters of MM and cancer as an isolated morbidity. The prevalence of MM in the older Brazilians was high, especially in female sex and persons living in the South region of Brazil. Use of network analysis could be an important tool for identifying MM clusters and address the appropriate health care, research, and medical education for older adults in Brazil.

Comparação entre os Efeitos da Ingestão de Sal do Himalaia e de Sal Comum sobre os Valores de Sódio Urinário e Pressão Arterial em Indivíduos Hipertensos / Comparison between the Effects of Hymalaian Salt and Common Salt Intake on Urinary Sodium and Blood Pressure in Hypertensive Individuals

Resumo Fundamento O sal do Himalaia (SH) tornou-se uma alternativa popular para o sal de mesa (SM) devido às suas alegações de benefícios à saúde, principalmente para indivíduos com hipertensão arterial. Porém, apesar do aumento do consumo de SH, ainda faltam evidências clínicas que sustentem a recomendação de seu consumo por profissionais de saúde. Objetivo Este estudo teve como objetivo comparar o impacto da ingestão de SH e SM sobre a pressão arterial sistólica (PAS), pressão arterial diastólica (PAD) e concentração de sódio urinário em indivíduos com PA. Métodos Este estudo recrutou 17 pacientes do sexo feminino com hipertensão arterial que comiam fora de casa no máximo uma vez por semana. Os participantes foram divididos aleatoriamente em dois grupos, para receber e consumir SH ou SM. Antes e depois de cada intervenção, os participantes tiveram sua pressão arterial medida e urina coletada para análise mineral. Um valor de p <0,05 foi considerado estatisticamente significativo. Resultados Não houve diferenças estatisticamente significativas antes e depois da intervenção SH para PAD (70 mmHg vs. 68,5 mmHg; p = 0,977), PAS (118,5 mmHg vs. 117,5 mmHg; p = 0,932) e concentração urinária de sódio (151 mEq / 24h vs. 159 mEq / 24; p = 0,875). Além disso, a análise entre os grupos não mostrou diferenças significativas após a intervenção em relação a PAS (117 mmHg vs 119 mmHg; p = 0,908), PAD (68,5 mmHg vs 71 mmHg; p = 0,645) ou concentração urinária de sódio (159 mEq / 24h vs 155 mEq / 24h; p = 0,734). Conclusão Este estudo sugere que não há diferenças significativas no impacto do consumo de SH em relação ao SM na PA e concentração urinária de sódio em indivíduos com hipertensão arterial.

Abstract Background The Himalayan salt (HS) has become a popular alternative for the traditional table salt (TS) due to its health benefit claims, particularly for individuals with arterial hypertension. However, despite the increase in HS consumption, there is still a lack of clinical evidence to support a recommendation for its consumption by health professionals. Objective This cross-over study aimed to compare the impact of HS and TS intake on systolic blood pressure (SBP) and diastolic blood pressure (DBP), and urinary sodium concentration in individuals with arterial hypertension. Methods This study recruited 17 female patients with arterial hypertension who ate out no more than once a week. Participants were randomized into two groups, to receive and consume either HS or TS. Before and after each intervention, participants had their blood pressure measured and urine collected for mineral analysis. A p-value < 0.05 was considered statistically significant. Results There were no statistically significant differences before and after the HS intervention for DBP (70mmHg vs. 68.5mmHg; p=0.977), SBP (118.5 mmHg vs. 117.5 mmHg; p= 0.932) and sodium urinary concentration (151 mEq/24h vs. 159 mEq/24; p=0.875). Moreover, the between-group analysis showed no significant differences after the intervention regarding SBP (117mmHg vs 119 mmHg; p=0.908), DBP (68.5 mmHg vs. 71mmHg; p= 0,645) or sodium urinary concentration (159 mEq/24h vs. 155 mEq/24h; p=0.734). Conclusion This study suggests that there are no significant differences on the impact of HS consumption compared to TS on blood pressure and sodium urinary concentration in individuals with arterial hypertension.

Antihypertensive effect of Equisetum arvense L.: a double-blind, randomized efficacy and safety clinical trial.

BACKGROUND: Equisetum arvense L. (EA) is a traditional phytomedicine used as a diuretic agent worldwide and regulated strictly by European Medicine Agency (EMA) and Brazilian National Health Surveillance Agency (ANVISA). However, few studies evaluating its efficacy and safety have been published and no clinical trial assessing its antihypertensive effect has been reported to date. PURPOSE: To assess antihypertensive effect, safety and tolerability of EA compared to hydrochlorothiazide (HCTZ). METHODS: This is a double-blind randomized clinical trial, allocating 58 systemic arterial hypertension (SAH) stage I patients (both sexes, 25-65 years old) into two groups (EA and HCTZ). All patients underwent biochemical and cardiologic checkup prior to and during interventions. The EA standardized dry extract (900 mg/day) or HCTZ (25 mg/day) were administered for 3 months and follow-up visits were conducted every 30 days. Efficacy established goals were systolic blood pressure (SBP) and/or diastolic blood pressure (DBP) decreases ≥ 10.0 mmHg and/or casual blood pressure (CBP) < 140/90 mmHg. RESULTS: EA treatment demonstrated a significant antihypertensive effect, promoting a mean decrease of SBP and DBP by 12.6 and 8.1 mmHg, respectively, and resulting a CBP mean of 134.0/84.5 mmHg at the end of intervention on the SAH stage I patients (CBP mean of 148.5/95.7 mmHg). There were no significant statistical differences between EA and HCTZ interventions on blood pressure decrease, and before-after treatments regarding to biochemical tests and signs of acute toxicity, renal, hepatic and hematologic alterations. A slight trend but no significant difference were observed between adverse events from EA (3.58%) and HCTZ (4.68%) groups. CONCLUSION: EA standardized dry extract was successfully applied to the SAH stage I patient treatment, decreasing effectively SBP ad DBP values to the reference normal ranges, and demonstrating a well-tolerability profile similar to HCTZ intervention.

A SAGE score cutoff that predicts high-pulse wave velocity as measured by oscillometric devices in Brazilian hypertensive patients.

We aimed to identify the optimal cutoff SAGE score for Brazilian hypertensive patients who had their pulse wave velocity (PWV) measured with oscillometric devices. A retrospective analysis of patients who underwent central blood pressure measurement using a validated oscillometric device, the Mobil-O-Graph® (IEM, Stolberg, Germany), between 2012 and 2019 was performed. Patients with arterial hypertension and available data on all SAGE parameters were selected. An ROC curve was constructed using the Youden index to define the best score to identify patients at high risk for high PWV. A total of 837 patients met the criteria for SAGE and diagnosis of hypertension. The median age was 59.0 years (interquartile range [IQR]: 47.0-68.0), and 50.7% of the patients were women. The following comorbidities and conditions were present: dyslipidemia (37.4%), diabetes (20.7%), a body mass index score ≥30 kg/m2 (36.6%), use of antihypertensive drugs (69.5%), and smoking (18.3%). The median peripheral blood pressure was 128 mmHg (IQR: 117-138 mmHg) for systolic and 81 mmHg (IQR: 73-90 mmHg) for diastolic blood pressure. The median PWV was 8.3 m/s (7.1-9.8 m/s), and the prevalence of high PWV (≥10 m/s) was 22.9% (192 patients). A cutoff SAGE score ≥8 was effective at identifying a high risk of PWV ≥ 10 m/s, achieving 67.19% sensitivity (95% CI: 60.1-73.8) and 93.95% specificity (95% CI: 91.8-95.7). With this cutoff point, 1 out of every 5 treated hypertensive patients would be referred for a PWV measurement. A SAGE score of ≥8 identified Brazilian hypertensive patients with a high risk of future cardiovascular events (PWV ≥ 10 m/s).

Abstract Objective To analyze scientific publications regarding the challenges for the construction and insertion of health policies aimed at the male population in Brazil and in the world. Methods This is an integrative literature review with the inclusion of studies that discussed men's health policies. Search was performed in July 2020 and January 2022 in the Public/Publish MEDLINE (PubMed), Scopus, Embase and Web of Science databases. Articles in Portuguese, Spanish and English were included, without restriction of publication date. The searches were obtained by crossing the bases with the following descriptors: Men's Health, Health Policy, Men. Results A total of 1,709 articles were identified. After the selection and analysis process, 29 studies made up the sample. It was found that 79.5% of studies were conducted in Brazil, 6.9% in the United Kingdom, 3.4% involving countries on the Asian continent, 3.4% in Ireland and Australia, 3.4% in Scotland and 3.4% in the European Union. They were published between 2008 and 2021. From the analysis, the following categories emerged: Lack of knowledge and recognition of male policies; (De)construction of male policies. Conclusion Regardless of the country, gender stereotypes and the inability of managers, health professionals and men themselves to recognize the policy were the main challenges in the construction and insertion of policies for the male population. It is considered necessary to legitimize comprehensive care for men as a social movement and governmental policy, aiming at improving the quality of management and clinical practice.

Associação da autopercepção da qualidade de vida e saúde, prática de atividade física e desempenho funcional entre idosos no interior do Brasil / Association of self-perceived quality of life and health, physical activity and functional performance among older adults in the interior of Brazil

Resumo Objetivo analisar a autopercepção de saúde e da qualidade de vida associados aos fatores contextuais em idosos não institucionalizados em município rural no interior do Brasil. Método Estudo transversal de base populacional. Foram incluídos indivíduos com 60 anos ou mais, não institucionalizados, residentes em município com características rurais. Foram utilizadas variáveis sociodemográficas, autopercepção da saúde e da qualidade de vida, nível de atividade física e desempenho funcional. Os dados foram coletados em domicílio com aplicação de entrevista e dos instrumentos: WHOQOL BREF, Questionário Internacional de Atividade Física (IPAQ) e teste Timed Up and Go (TUG). Para a análise de comparação e associação foram aplicados os testes qui-quadrado ou exato de Fisher e Razão de Prevalência (RP) e intervalos de confiança (IC). Resultados Participaram do estudo 142 idosos, sendo 58,5% do sexo feminino, com média de idade de 72,4 (±8,0) anos. A autopercepção da saúde foi associada à prática de atividade física (RP=1,13, IC=1,01-1,27) e ao desempenho funcional (RP=1,24, IC=1,03-1,48). A percepção da saúde (RP=1,66, IC=1,57-1,76) e qualidade de vida (RP=1,70, IC=1,60-1,79) boa/muito boa foi associada de forma positiva à prática de atividade física e independência funcional. Conclusão A prática de atividade física e a manutenção da independência funcional contribuem de forma significativa para uma percepção positiva da saúde e qualidade de vida. Porém, idosos insuficientemente ativos e independentes também podem ter boa percepção da saúde. Recomendam-se intervenções nas políticas públicas que considerem características intrínsecas de cada população visando manter ou melhorar a percepção de saúde e qualidade de vida dos idosos.

Abstract Objective to analyze self-perception of health and quality of life associated with contextual factors in non-institutionalized older adults people in a rural municipality in the interior of Brazil. Method Cross-sectional population-based study. Individuals aged 60 years or more, not institutionalized, living in a municipality with rural characteristics were included. Sociodemographic variables, self-perceived health and quality of life, level of physical activity and functional performance were used. Data were collected at home with application of interviews and instruments: WHOQOL BREF, International Physical Activity Questionnaire (IPAQ) and Timed Up and Go test (TUG). For the comparison and association analysis, the chi-square or Fisher's exact test and the Prevalence Ratio (PR) and confidence intervals (CI) were applied. Results The study involved 142 older adults, 58.5% female, with a mean age of 72.4 (±8.0) years. Self-perceived health was associated with the practice of physical activity (PR=1.13, CI=1.01-1.27) and with functional performance (PR=1.24, CI=1.03 -1.48). The perception of good/very good health (PR=1.66, CI=1.57-1.76) and quality of life (PR=1.70, CI=1.60-1.79) was associated with positive to the practice of physical activity and functional independence. Conclusion The practice of physical activity and maintenance of functional independence significantly contribute to a positive perception of health and quality of life. However, elderly people who are insufficiently active and independent may also have a good perception of health. Interventions in public policies that consider the intrinsic characteristics of each population are recommended, aiming to maintain or improve the perception of health and quality of life of the elderly.
