ABSTRACT

This study reports the clinical use of two sevoflurane-based anesthetic techniques in dogs undergoing craniectomy. Twenty-one animals undergoing elective rostrotentorial or transfrontal craniectomy for brain tumor excision, anesthetized with sevoflurane, were enrolled in this retrospective, observational study. Anesthetic records were allocated to two groups: Sevo-Op (sevoflurane and short acting opioid infusion): 8 dogs and Sevo-Dex (sevoflurane and dexmedetomidine infusion): 13 dogs. Average mean arterial pressure (MAP), heart rate, end-tidal carbon dioxide, end-tidal sevoflurane and intraoperative infusion rates during surgery were calculated. Presence of intra-operative and post-operative bradycardia, tachycardia, hypotension, hypertension, hypothermia, hyperthermia was recorded. Time to endotracheal extubation, intraoperative occurrence of atrioventricular block, postoperative presence of agitation, seizures, use of labetalol and dexmedetomidine infusion were also recorded. Data from the two groups were compared with Fisher's exact test and unpaired t tests with Welch's correction. Odds ratio (OR) and 95% confidence interval (CI) were calculated for categorical variables. Intra-operatively, MAP was lower in Sevo-Op [85 (± 6.54) vs. 97.69 (± 7.8) mmHg, p = 0.0009]. Time to extubation was longer in Sevo-Dex [37.69 (10–70) vs. 19.63 (10–25), p = 0.0033]. No differences were found for the other intra-operative and post-operative variables investigated. Post-operative hypertension and agitation were the most common complications (11 and 12 out of 21 animals, respectively). These results suggest that the infusion of dexmedetomidine provides similar intra-operative conditions and post-operative course to a short acting opioid infusion during sevoflurane anesthesia in dogs undergoing elective rostrotentorial or transfrontal intracranial surgery.

ABSTRACT

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


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

ABSTRACT

Los jóvenes con hipertensión arterial pueden manifestar efectos adversos en órganos blanco como el corazón y la vasculatura, incluyendo hipertrofia ventricular izquierda, aumento de la rigidez arterial y aumento del grosor de la carótida. También existe evidencia reciente de efectos adversos debido a hipertensión en el cerebro, hallazgo con implicancias significativas del impacto de la hipertensión arterial primaria en la cognición, tanto durante la infancia como a lo largo de la vida. En los últimos 15 años, estudios de bases de datos y estudios uni y multicéntricos han evidenciado que la presión arterial elevada en niños y adolescentes se asocia con un menor rendimiento en las pruebas neurocognitivas durante la juventud. Se presenta un resumen de la literatura sobre el efecto de la hipertensión arterial en la neurocognición en niños y jóvenes, así como también se analizan posibles mecanismos. El hallazgo de un rendimiento más bajo en las pruebas neurocognitivas en jóvenes hipertensos sugiere que el tratamiento de la hipertensión arterial en la adolescencia podría representar una oportunidad para mejorar el deterioro posterior y, por lo tanto, mejorar la salud cognitiva futura


Youth with hypertension can manifest adverse target-organ effects on the heart and vasculature, including left ventricular hypertrophy, increased arterial stiffness, and increased carotid thickness. There is emerging evidence for hypertensive adverse effects on the brain as well, findings with significant implications for the impact of primary hypertension on cognition both during childhood and later in life. Over the past 15 years, database, single-center, and multicenter studies have provided evidence that elevated BP in children and adolescents is associated with lower performance on neurocognitive testing during youth itself. In this review, we summarize the literature on the effect of hypertension on neurocognition in youth as well as review possible mechanisms of altered cognition. The finding of lower neurocognitive test performance in hypertensive youth suggests that treatment of hypertension from adolescence may represent an opportunity to ameliorate subsequent cognitive decline and thereby improve downstream cognitive health

ABSTRACT

Introduction: Tonsillectomy is one of the most common otolaryngology procedures performed worldwide. It is also one of the first procedures learnt by residents during their training period. Although tonsillectomy is viewed relatively as a low-risk procedure, it can be potentially harmful because of the chance of posttonsillectomy hemorrhage. Objective: The objective of the present study is to analyze the effects of peroperative factors and experience of the surgeon on the incidence and pattern of posttonsillectomy reactionary hemorrhage. Methods: A retrospective review of medical charts was performed from 2014 to 2017 in a tertiary care hospital. A total of 1,284 patients who underwent tonsillectomy and adenoidectomy were included in the study. The parameters assessed were experience of the surgeon, operating time, intraoperative blood loss, difference in mean arterial pressure (MAP) and pulse rate. Results: A total of 23 (1.79%) out of the 1,284 patients had reactionary hemorrhage. Out of those 23, 16 (69.5%) patients had been operated on by trainees, while 7 (30.5%) had been operated on by consultants (p = 0.033, odds ratio [OR] = 0.04). Operating time, intraoperative blood loss, difference in MAP and pulse rate were significantly higher in the reactionary hemorrhage group, and showed a positive association with risk of hemorrhage (p < 0.05; OR >1). Re-exploration to control the bleeding was required in 10 (76.9%) out of the 23 cases. Conclusion: The experience of the surgeon experience and peroperative factors have an association with posttonsillectomy hemorrhage. Close surveillance and monitoring of the aforementioned peroperative factors will help in the identification of patients at risk of hemorrhage (AU)

ABSTRACT

Objetivo: Identificar a melhor evidência científica sobre a correta aferição da pressão arterial. Métodos: revisão sistematizada da literatura com levantamento em ambiente virtual no período de setembro a dezembro de 2016, com textos publicados nas bases virtuais LILACS, PubMed, SciELO e Scopus. O material foi lido e as informações organizadas em quadro. Resultados: foram obtidos 12 artigos, oito abordavam a técnica de aferição em dois tempos, dois discutiram a eficácia de valores obtidos com aparelhos digitais, um debateu a eficácia do rastreômetro, e um comparou a aferição invasiva e não invasiva. Conclusão: o método indireto auscultatório é o mais utilizado para aferição de pressão arterial. Nesse procedimento inclui-se a técnica em dois tempos, considerada padrão ouro na acurácia dos valores e recomendada por normatizações. Recursos como aparelho digital e rastreômetro não apresentam a mesma acurácia, porém são importantes no diagnóstico da hipertensão. São alternativas para garantir a confiabilidade da medida das cifras: estabelecer protocolos para o procedimento, fornecer equipamentos adequados e educação continuada.(AU)


Objective: To identify the best scientific evidence on the correct measurement of arterial pressure. Methods: Systematic review of the literature with a virtual environment survey from September to December 2016, with texts published in the virtual databases LILACS, PubMed, SciELO and Scopus. The material has been read, and the information organized in frame. Results: Twelve articles were obtained, eight were on the technique of measurement in two times, two discussed the effectiveness of values obtained with digital devices, one discussed the effectiveness of the trace meter, and one compared the invasive and noninvasive measurement. Conclusion: the indirect auscultatory method is the most used for blood pressure measurement. This procedure includes the two-stroke technique, considered gold standard in the accuracy of values and recommended by standardization. Features such as digital apparatus and tracker do not present the same accuracy, but are important in the diagnosis of hypertension. They are alternatives to guarantee the reliability of the measurement of the numbers: to establish protocols for the procedure, to provide adequate equipment and continuous education.(AU)

ABSTRACT

RESUMO Objetivo Avaliar modificações cardiorrespiratórias em decorrência de sessão única de oxigenoterapia hiperbárica. Método Estudo aleatorizado com pacientes: grupos-controle e oxigenoterapia hiperbárica. As avaliações ocorreram no início, durante e após a exposição ao oxigênio puro acima de uma atmosfera, durante 2 horas. A pressão arterial sistêmica, saturação periférica de oxigênio, frequência de pulso, volume e capacidade pulmonar, pressões inspiratória e expiratória máximas foram avaliadas. A saturação periférica de oxigênio, frequência de pulso e pressão arterial sistêmica foram avaliadas durante a pressurização na primeira hora. Os dados foram avaliados pelo teste de ANOVA, Mann-Whitney e teste t independente (p<0,05). Resultados Foram avaliados 14 pacientes adultos. No grupo sob terapia (sete sujeitos), idade: 49,57±14,59 anos houve redução da frequência de pulso de 16 batimentos por minuto após 35 minutos de terapia (análise intragrupo), e a saturação periférica de oxigênio foi maior neste mesmo período se comparado ao grupo-controle. Conclusão A oxigenoterapia hiperbárica promove alterações cardiorrespiratórias com o aumento da saturação periférica de oxigênio e redução da frequência de pulso, sem alterar os níveis pressóricos arteriais e a força, volumes e capacidades respiratórios.

ABSTRACT Objective To evaluate cardiorespiratory alterations due to a single session of hyperbaric oxygen therapy. Method Randomized study with patients: a control group and hyperbaric oxygen therapy. Evaluations occurred in the beginning, during, and after exposure to pure oxygen above atmosphere for 2 hours. Systemic blood pressure, peripheral oxygen saturation, pulse rate, lung volume and lung capacity, and maximal inspiratory and expiratory pressures were evaluated. Peripheral oxygen saturation, pulse rate, and systemic blood pressure were evaluated during the pressurizing in the first hour. Data were evaluated by means of ANOVA, Mann-Whitney, and independent t-test (p<0.05). Results A total of 14 adult patients were evaluated. In the group under therapy (seven subjects), aged: 49.57±14.59 years, there was a decrease in the pulse rate of 16 beats per minute after 35 minutes of therapy (intragroup analysis), and the peripheral oxygen saturation was higher within the same period compared to the control group. Conclusion The hyperbaric oxygen therapy promotes cardiorespiratory alterations with the increase of the peripheral oxygen saturation and decrease of the pulse rate, without altering blood pressure levels and the strength, volumes, and respiratory capacities.

ABSTRACT

Resumen La terapia con oxígeno a largo plazo mejoró la supervivencia de los pacientes con enfermedad pulmonar obstructiva crónica. Las medidas propuestas en las guías clínicas para evaluar la indicación y seguimiento de esta terapia son la presión arterial de oxígeno y la saturación arterial de oxígeno. Se ha generalizado el uso de la oximetría de pulso, pero la información para determinar si estas medidas son intercambiables es insuficiente. El objetivo es revisar los fundamentos fisiológicos de las variables relacionadas con la oxigenación y sus formas de medición. En la evaluación del paciente con patología respiratoria, la saturación de pulso es una ayuda clínica valiosa, sin embargo, sus limitaciones no le permiten, en ciertos rangos, reemplazar la valoración directa en sangre arterial (gasometría arterial) de la saturación arterial y la presión arterial de oxígeno, para determinar la indicación de la oxigenoterapia. MÉD.UIS.2019;32(3):19-25


Abstract Long-term oxygen therapy improves the survival of patients with chronic obstructive pulmonary disease. Measures proposed in clinical clinics to evaluate the indication and monitoring of arterial blood pressure therapy and arterial oxygen saturation. The use of pulse oximetry has been widespread, but the information to determine if these measures are interchangeable is insufficient. The objective is to review the physiological foundations of variables related to oxygenation and their forms of measurement. In the assessment of the patient with respiratory pathology, pulse saturation is a valuable clinical aid., however, its limitations do not allow, in certain ranges, to replace direct arterial blood pressure (arterial blood gas) measurement of arterial saturation and arterial oxygen pressure, to determine the indication of oxygen therapy.

ABSTRACT

La exposición a ruido tiene un potencial importante para causar daños a la salud de los trabajadores con efectos auditivos y extra auditivos. El objetivo de la presente investigación fue determinar los niveles de ruido a los que se encuentran expuestos los trabajadores del transporte público de la ciudad de Chihuahua, México, durante la jornada laboral y su asociación con los posibles efectos en la presión arterial. Para ello, se realizaron mediciones de ruido en el ambiente laboral con un dosímetro. Para la medición de presión arterial se utilizó el monitor ambulatorio, el cual mide la presión arterial durante el desarrollo de las actividades laborales. Los parámetros bioquímicos que se midieron fueron colesterol y triglicéridos en ayunas. Con base en los resultados y al análisis de datos se encontró elevada la presión arterial (hipertensión), ruido inestable con variaciones de hasta 106.7 decibeles A (dB A) y un aumento en los lípidos en sangre (triglicéridos). Los resultados nos permiten proponer que la constante exposición al ruido de los choferes de transporte público, es un factor de riesgo importante para el desarrollo de alta presión arterial y un incremento en los niveles de triglicéridos, lo que aumenta el riesgo de sufrir enfermedades cardiovasculares(AU)


Occupational noise exposure can lead to both hearing and non-hearing effects on workers' health. The objective of this study was to measure ambient noise levels that public transportation workers in Chihuahua, Mexico are exposed to, and their association with blood pressure, using a standard noise level dosimeter. We used ambulatory monitors to measure blood pressure over the work shift, and also measured serum cholesterol and triglycerides. Noise levels varied widely, with peaks up to 106.7 decibels (A-scale); we also found elevated blood pressure and triglycerides. Our results suggest that, among public transportation drivers, continuous exposure to noise is a risk factor for elevated blood pressure and triglycerides which, in turn, are risk factors for cardiovascular disease(AU)

ABSTRACT

O presente manuscrito teve por objetivo a revisão de literatura sobre os efeitos do destreinamento (DT) no sistema cardiovascular e em fatores de risco cardiovasculares, tais como massa corporal, adiposidade e perfil lipídico. Para isso, uma ampla pesquisa da literatura nas bases de dados PubMed, Scopus e Web of Science foi realizada, e o conjunto de dados mostrou que o DT promove reversão das adaptações cardiovasculares obtidas com o treinamento físico, tais como redução do VO2máx, do débito cardíaco máximo, do volume sistólico, do volume sanguíneo e da massa ventricular. Além disso, o DT induz aumento da frequência cardíaca de repouso e submáxima, da resistência vascular periférica e da pressão arterial. O curso temporal para que tais efeitos cardiovasculares ocorram é amplo, podendo ocorrer a partir da segunda semana de DT até três meses após o DT. O DT também gera prejuízos aos fatores de risco cardiovasculares, tais como aumento da massa corporal e da adiposidade, aumento do colesterol total, LDL e VLDL, e redução do HDL. Enquanto os efeitos na massa corporal aparecem após quatro semanas de DT, as mudanças no perfil lipídico são mais precoces, com apenas uma semana de DT


The objective of this manuscript is to review the literature about the effects of detraining (DT) on the cardiovascular system and on cardiovascular risk factors such as body mass, adiposity and lipid profile. For this, a wide literature search in the PubMed, Scopus and Web of Science databases was performed, and the data showed that DT promotes the reversal of cardiovascular adaptations obtained with physical training, such as reduction in VO2 max, cardiac output, ejection fraction, blood volume and ventricular mass. In addition, DT induces an increase in resting and submaximal heart rates, peripheral vascular resistance and blood pressure. The timeframe for such cardiovascular effects to be seen is long, which may occur from the second week of DT to 3 months after DT. DT also causes damage to cardiovascular risk factors by inducing an increase in body mass and adiposity, an increase in total cholesterol, LDL and VLDL, and a reduction in HDL. While effects on body mass appear after 4 weeks of DT, changes in lipid profile appear earlier, with only 1 week of DT

ABSTRACT

O exercício físico é recomendado no tratamento da hipertensão arterial. Agudamente, a execução do exercício promove aumento da pressão arterial (PA), mas, no período de recuperação pós-exercício, é possível evidenciar redução da PA e, principalmente, após um período de treinamento físico crônico, pode haver diminuição da PA clínica e de 24 horas dos hipertensos. Apesar desses efeitos serem conhecidos, sua magnitude e mecanismos dependem do tipo de exercício executado e de suas características. Este artigo revê os efeitos agudos e crônicos clássicos do exercício aeróbico e os efeitos mais recentemente estudados dos exercícios resistidos isométrico e dinâmico na PA, seus mecanismos e fatores de influência, ressaltando os pontos que embasam as recomendações atuais sobre o uso do exercício na hipertensão arterial. O conhecimento atual demonstra que: 1) o exercício aeróbico promove aumento da PA sistólica durante sua execução, gera hipotensão pós-exercício clinicamente relevante e reduz a PA clínica e de 24 horas após o treinamento; 2) o exercício resistido isométrico promove aumento progressivo da PA sistólica e diastólica durante sua execução, não produz hipotensão pós-exercício consistente e reduz a PA clínica após o treinamento, mas esse efeito hipotensor ocorre com um protocolo específico de exercício de handgrip; e 3) o exercício resistido dinâmico promove grande aumento da PA sistólica e diastólica durante sua execução, gera hipotensão pós-exercício cuja relevância clínica ainda precisa ser comprovada e parece diminuir a PA clínica, mas não a ambulatorial, após o treinamento. Face a esses conhecimentos, o treinamento aeróbico complementado pelo resistido dinâmico é recomendado na hipertensão


Physical exercise is recommended for hypertension treatment. Acutely, exercise execution increases blood pressure (BP), but, during the recovery period, BP decreases, and after a chronic training period, clinic and ambulatory BP may decrease in hypertensives. Despite these known effects of exercise, their magnitude and mechanisms depend on the type of exercise and its characteristics. This article reviews the classical acute and chronic effects of aerobic exercise and the more recent knowledge about isometric and dynamic resistance exercises on BP, its mechanisms and factors of influence, highlighting the aspects underlying exercise recommendations for hypertension. Current scientific knowledge shows that: 1) aerobic exercise increases systolic BP during its execution, produces a clinically significant post-exercise hypotension, and chronically decreases clinic and 24-hour BP; 2) isometric resistance exercise produces a progressive increase in systolic and diastolic BP during its execution, does not promote consistent post-exercise hypotension, and decreases clinic BP after training, but this hypotensive effect results from a specific protocol of isometric handgrip; and 3) dynamic resistance exercise produces a huge progressive increase in systolic and diastolic BP during its execution, promotes post-exercise hypotension with questionable clinical relevance, and seems to decrease clinic but not ambulatory BP after training. Based on this current knowledge, regular aerobic exercise complemented by dynamic resistance exercise is recommended for hypertension

Neuromuscular electrical stimulation seems to be a promising option to intensify the rehabilitation and improve the exercise capacity of patients in the immediate postoperative period of cardiac surgery. Objective: This study aimed to evaluate the hemodynamic (heart rate, systolic blood pressure, diastolic blood pressure, and mean blood pressure) and respiratory (respiratory rate and oxygen saturation) responses to neuromuscular electrical stimulation in the immediate postoperative period in patients submitted to cardiac surgery and to verify its feasibility and safety. Methods: This is a pilot randomized controlled trial, wherein critical patients in the immediate postoperative period of cardiac surgery were randomly assigned to a control group, using sham neuromuscular electrical stimulation, or an experimental group, submitted to neuromuscular electrical stimulation sessions (FES), for 60 min, with a 50-Hz frequency, 200-µs pulse duration, time on: 3 s, and time off: 9 s. Data distribution was evaluated by the Shapiro-Wilk test. The analysis of variance was used and a p-value < 0.05 was considered significant. Results: Thirty patients were included in the study. The neuromuscular electrical stimulation was applied within the first 23.13 ± 5.24 h after cardiac surgery, and no changes were found regarding the hemodynamic and respiratory variables between the patients who underwent neuromuscular electrical stimulation, and those in the control group. Conclusions: In the present study, neuromuscular electrical stimulation did not promote changes in hemodynamic and respiratory responses of patients in the immediate postoperative period of cardiac surgery

ABSTRACT

Self-selected exercise intensity (SSE) is a simple approach to encourage an active lifestyle. This study aimed to investigate whether a SSE session meet the recommended intensity for hypertension management (i.e. moderate-vigorous), and whether heart rate (HR), rating of perceived exertion (RPE) and affective responses are reproducible. Thirteen inactive hypertensive older women (age: 64.54 ± 4.16 years; blood pressure: 122.51/62.15 mmHg) performed two 30-minute SSE sessions outdoors. HR reserve (HRR), RPE and affective responses were assessed. Paired t-test, intraclass correlation coefficient (ICC) and typical error (TE) were used for the analyzes. Participants exercised at moderate-vigorous intensity (≥ 40% of HRR). No differences were found for HRR (56.46 ± 8.01% vs. 59.08 ± 10.57%), RPE (11.26 ± 1.14 vs. 10.98 ± 1.52) and affective response (3.47 ± 1.13 vs. 3.38 ± 1.23) (p > 0.05). RPE showed excellent reliability (ICC = 0.82; 95%CI: 0.42; 0.94; p = 0.003). There was a poor reliability for HRR (ICC = 0.40; 95%CI: -0.97; 0.82; p = 0.193) and affective responses (ICC = 0.19; 95%CI: -2.10; 0.76; p = 0.369). TE between sessions for HRR, RPE, and affective response were 8.11 bpm, 0.75 and 1.11, respectively. In conclusion, inactive hypertensive older women seem to meet the recommended intensity for hypertension management when they exercise at a self-selected pace and report it as light-moderate and pleasant. Despite only RPE, but not HR and affective response, has shown good reproducibility, the results seem to support the use of SSE as a simple approach to encourage an active lifestyle in this population


O exercício em intensidade autosselecionada (EIA) é uma abordagem simples para encorajar um estilo de vida ativo. Este estudo investigou se o EIA atende a intensidade recomendada para tratamento de hiperten-são (i.e. moderada-vigorosa), e se a frequência cardíaca (FC), percepção de esforço (PSE) e resposta afetiva são reprodutíveis. Treze mulheres idosas hipertensas inativas (idade: 64,54 ± 4,16 anos; pressão arterial: 122,51/62,15 mmHg) realizaram duas sessões de EIA de 30 minutos ao ar livre. FC de reserva (FCR), PSE e resposta afetiva foram avaliadas. Teste t pareado, coeficiente de correção intraclasse (CCI) e erro tí-pico (ET) foram analisados. As participantes se exercitaram em intensidade moderada-vigorosa (≥ 40% da FCR). Não houve diferença na FCR (56,46 ± 8,01% vs. 59,08 ± 10,57%), PSE (11,26 ± 1,14 vs. 10,98 ± 1,52) e resposta afetiva (3,47 ± 1,13 vs. 3,38 ± 1,23; p > 0,05). A PSE apresentou excelente confiabilidade (CCI = 0,82; IC95%: 0,42; 0,94; p = 0,003). Houve baixa confiabilidade da FCR (CCI = 0,40; IC95%: -0,97; 0,82; p = 0,193) e resposta afetiva (CCI = 0,19; IC95%: -2,10; 0,76; p = 0,369). O ET foi de 8,11 bpm, 0,75 e 1,11 para FCR, PSE e resposta afetiva, respectivamente. Em conclusão, mulheres idosas hipertensas inativas parecem atender a intensidade recomendada para tratamento da hipertensão quando realizam EIA e relatam a atividade como leve-moderada e prazerosa. Embora apenas a PSE, e não a FCR e resposta afetiva, tenha mostrado boa reprodutibilidade, os resultados parecem suportar o EIA como uma abordagem simples para encorajar um estilo de vida ativo nessa população

ABSTRACT

O objetivo do presente estudo foi levantar, na literatura atual, estudos relevantes que identifiquem as possíveis respostas hemodinâmicas encontradas em indivíduos hipertensos praticantes do Método Pilates. A revisão sistemática conduzida conforme as recomendações PRISMA em cinco bases de dados eletrônicas (PEDro, PubMed, SciELO, LILACS e Cochrane), disponibilizado desde o início das bases até Março de 2019, com descritores MESH conforme segue: [("Adult" OR "Young adult" OR "Middle Aged" OR "Aged" OR "Elderly") AND ("exercise movement techniques" OR "Pilates-Based Exercises" OR "Pilates Training") AND ("Hemodynamics" OR "Heart Rate" OR "Cardiac Chronotropy" OR "Heart Rate Control" OR "hypertension" OR "Blood Pressure" OR "High Blood Pressure" OR "Systolic Pressure" OR "Diastolic Pressure" OR "High Blood Pressure" OR "Pulse Rate Determination")], posteriormente ajustado para as demais bases. Busca complementar manual nas referências dos artigos incluídos na pesquisa e Google Scholar. Foram incluídos estudos de intervenção, com idade maior ou igual a 18 anos; diagnóstico de hipertensão arterial sistêmica (HAS); submetidos a exercícios de pilates solo e/ou pilates aparelhos como método de intervenção e incluído a descrição de análise das variáveis hemodinâmicas de pressão arterial (PA), frequência cardíaca (FC) e duplo produto (DP). Após processo de seleção foi selecionado apenas um único estudo que tenha contemplado todos os critérios de elegibilidade, totalizando 44 indivíduos do sexo feminino, com média de idade de 50,5 anos (±6,3 anos), hipertensas com utilização de medicação, onde 22 foram submetidas ao pilates solo e 22 permaneceram no grupo controle. O estudo apresentou resultados positivos na frequência cardíaca (FC), pressão arterial (PA) e no duplo-produto (DP) em comparação ao grupo controle. Apesar do número limitado de manuscritos encontrados nesta revisão, os resultados das variáveis hemodinâmicas nos levam a considerar plausível a utilização do Mat pilates em pacientes com HAS. Entretanto, novos estudos devem ser realizados para a confirmação dos achados...(AU)


The aim this study was to raise in the current literature relevant studies that identify the possible hemodynamic responses found in hypertensive individuals practicing the Pilates Method. The systematic review conducted according to PRISMA recommendations in five electronic databases (PEDro, PubMed, SciELO, LILACS and Cochrane), available from the beginning of the databases until March 2019, with MESH descriptors as follows: [("Adult "OR" Young adult "OR" Middle Aged "OR" Aged "OR" Elderly ") AND (" Exercise Movement Techniques "OR" Pilates-Based Exercises "OR" Pilates Training ") AND (" Hemodynamics "OR" Heart Rate " OR "Cardiac Chronotropy" OR "Heart Rate Control" OR "Hypertension" OR "Blood Pressure" OR "High Blood Pressure" OR "Systolic Pressure" OR "Diastolic Pressure" OR "High Blood Pressure" OR "Pulse Rate Determination")] , later adjusted to the other bases. Manual complementary search in the references of the articles included in the search and Google Scholar. Intervention studies, 18 years of age or older were included; diagnosis of systemic arterial hypertension (SAH); submitted to solo pilates exercises and / or pilates apparatus as intervention method and included the description of analysis of hemodynamic variables of blood pressure (BP), heart rate (HR) and double product (SD). After the selection process, only one study was selected that met all the eligibility criteria, totaling 44 female individuals, with a mean age of 50.5 years (± 6.3 years), hypertensive with medication use, where 22 were submitted to solo pilates and 22 remained in the control group. The study showed positive results in heart rate (HR), blood pressure (BP) and double product (SD) compared to the control group. Despite the limited number of manuscripts found in this review, the results of hemodynamic variables lead us to consider the use of Mat pilates in patients with hypertension to be plausible. However, further studies should be performed to confirm the findings...(AU)

ABSTRACT

Hypertensive patients have high blood pressure and poor cardiovascular health and it is known that hypertension negatively affects people's health-related quality of life. Meta-analyses have shown that isometric handgrip training (IHT) reduces blood pressure in hypertensives, but the effects of IHT on health-related quality of life is unknown. Therefore, we tested the hypotheses that the IHT improves health-related quality of life in hypertensives. In this randomized controlled trial, 48 hypertensive individuals were randomly assigned to two groups: IHT and control. IHT was completed thrice weekly (4 × 2 min at 30% of maximal voluntary contraction). Before and after 12 weeks healthrelated quality of life was assessment through Medical Outcomes Study Questionnaire Short Form 36 (SF36). No significant effect was observed for physical function (IHT: 85.6±4.6 vs. 81.1±7.2; Control: 78.6±76.7±4.9), physical problems (IHT: 71.4±10.1vs. 83.9±8.1; Control: 73.8±8.2 vs. 64.3±8.0), general health (IHT: 56.1±3.7 vs. 57.1±1.9; Control: 54.3±1.6 vs. 57.6±2.1), pain (IHT: 23.6±4.6 vs. 30.7±5.8; Control: 32.9±4.5 vs. 31.9±4.3), social aspects (IHT: 46.4±3.6 vs. 50.0±2.3; Control: 48.8±2.7 vs. 48.8±1.7), emotional problems (IHT: 85.7±8.4 vs. 92.9±5.2; Control: 79.4±7.8 vs. 71.4±6.6), mental health (IHT: 61.7±2.8 vs. 58.0±2.5; Control: 54.5±2.4 ± 55.6±1.9), and vitality (IHT: 60.0±4.3 vs. 58.6±4.0; Control: 50.7±2.9 vs. 53.6±3.0) after 12-weeks of supervised IHT (p>0.05 for all). In conclusion, 12-weeks of IHT does not improve health-related quality of life in hypertensives. Therefore, in order to improve quality of life, other exercises should be an indicated for hypertensive patients...(AU)


Pacientes hipertensos têm pressão arterial elevada e saúde cardiovascular prejudicada, e, sabese que a hipertensão também afeta negativamente a qualidade de vida relacionada a saúde. Meta-análises têm demonstrado que o treinamento de exercício isométrico com handgrip (IHT) reduz pressão arterial, mas os efeitos do IHT na qualidade de vida relacionada a saúde são esconhecidos. Portanto, foi testado a hipótese que o IHT melhora a qualidade de vida relacionada a saúde em hipertensos. Nesse ensaio clínico controlado randomizado, 48 hipertensos foram randomizados em IHT e controle. IHT foi realizado três vezes semanais (4 x 2 minutos a 30% da contração voluntária máxima). Antes e após 12 semanas, a qualidade de vida relacionada a saúde foi avaliada pelo Medical Outcomes Study Questionnaire Short Form 36. Nenhum efeito significante foi observado para função física (IHT: 85,6±4,6 vs. 81,1±7,2; Controle: 78,6±76,7±4,9), problemas físicos (IHT: 71,4±10,1 vs. 83,9±8,1; Controle: 73,8±8,2 vs. 64,3±8,0), estado geral de saúde (IHT: 56,1±3,7 vs. 57,1±1,9; Controle: 54,3±1,6 vs. 57,6±2,1), dor (IHT: 23,6±4,6 vs. 30,7±5,8; Controle: 32,9±4,5 vs. 31,9±4,3), aspectos sociais (IHT: 46,4±3,6 vs. 50,0±2,3; Controle: 48,8±2,7 vs. 48,8±1,7), problemas emocionais (IHT: 85,7±8,4 vs. 92,9±5,2; Controle: 79,4±7,8 vs. 71,4±6,6), saúde mental (IHT: 61,7±2,8 vs. 58,0±2,5; Controle: 54,5±2,4 ± 55,6±1,9), e vitalidade (IHT: 60,0±4,3 vs. 58,6±4,0; Controle: 50,7±2,9 vs. 53,6±3,0) após 12 semanas de IHT (p>0.05 para todos). Em conclusão, 12 semanas de IHT não melhora a qualidade de vida relacionada a saúde em hipertensos. Portanto, para melhorar a qualidade de vida, outras modalidades de exercício deveriam ser indicadas para pacientes hipertensos...(AU)

ABSTRACT

La medición de los signos vitales es de gran importancia en el consultorio dental, de esta forma podemos obtener una visión objetiva y anticipada del estado funcional del paciente. Según la información obtenida, se tomarán decisiones terapéuticas. El odontólogo debe saber que el seguimiento clínico y el uso de la técnica adecuada para sus mediciones representan un aspecto muy relevante para prevenir emergencias en el consultorio dental. El odontólogo debe medir los signos vitales antes, durante y después del procedimiento dental y, del mismo modo, debe estar involucrado en la situación individual de cada paciente y proporcionar medidas higiénicodietéticas para mejorar su calidad de vida. La evaluación continua de los signos vitales durante el procedimiento quirúrgico dental, en el que se usan anestésicos locales, es particularmente relevante en este caso, ya que puede ayudarnos a prevenir complicaciones como arritmias cardiacas, crisis hipertensivas o angina de pecho. El objetivo de este artículo es promover en toda la profesión odontológica, el monitoreo de los signos vitales, su técnica de medición correcta y su correlación con otros datos de un historial completo médico y dental (AU)


The measurement of vital signs is of great importance in the dental office, this way we can obtain an objective and anticipated vision of the functional state of the patient. According to the information obtained, therapeutic decisions will be made. The dentist must know that monitoring and using the appropriate technique for its measurements, represents a very relevant aspect for the emergency in the dental office. The dentist must measure the vital signs before, during and after the dental procedure, likewise, they must be involved in the individual situation of each patient and provide hygienic-dietetic measures to improve their quality of life. The continuous assessment of vital signs during the dental surgical procedure, in which local anesthetics are used, is particularly relevant in this case since it can help us prevent complications such as cardiac arrhythmias, hypertensive crisis or angor pectoris. The objective of this article is to promote throughout the dental profession, the monitoring of vital signs, their correct measurement technique and their correlation with other data from a complete medical and dental history (AU)

ABSTRACT

A relação entre a prática de atividade física e pressão arterial (PA) tem sido reportada entre jovens. Contudo, pontos de corte do número de passos para discriminar PA elevada na população pediátrica ainda são incertos. O objetivo do presente estudo foi avaliar quantos passos por dia são suficientes para discriminar PA elevada em crianças e adolescentes. Estudo transversal com 1.044 escolares (456 meninos), de seis a 17 anos de idade, do município de Amargosa, Bahia, Brasil. A PA foi mensurada e a PA elevada foi classificada como sistólica ou diastólica ≥ percentil 95 de acordo com sexo, idade e estatura. O número de passos diários foi estimado por pedômetro. Curvas Receiver Operating Characteristic foram construídas e a área sob a curva, sensibilidade, especificidade e intervalos de confiança (IC) de 95% foram calculados, com análises separadas por sexo. A prevalência de PA elevada foi de 27,8%. O número de passos foi preditor de PA elevada tanto para o sexo masculino (acurácia = 0,55; IC95%: 0,51-0,60) quanto para o feminino (acuraria = 0,58; IC95%: 0,54-0,62). Os pontos de corte com maior equilíbrio entre sensibilidade e especificidade foram 14.228 passos para o sexo masculino e 10.796 passos para o feminino. O número de passos por dia, avaliado por pedômetro, foi preditor de PA elevada nas crianças e adolescentes investigados. Em termos práticos, sugere-se a utilização de 14.000 e 11.000 passos por dia para discriminar PA elevada em jovens do sexo masculino e feminino, respectivamente. Esses achados podem ser úteis para subsidiar ações de enfrentamento à PA elevada na infância e adolescência


The relationship between physical activity and blood pressure (BP) in children and adolescents has been extensively studied. However, step count cut-off points that discriminate high BP in the pediatric population are still uncertain. Thus, this study aimed to determine how many steps per day are enough to discriminate high BP in children and adolescents. Cross-sectional study involving 1,044 schoolchildren (456 boys) aged 6 to 17 years from the city of Amargosa, Bahia, Brazil. Blood pressure was measured and a high BP was defined as a systolic or diastolic value ≥ 95th percentile according to sex, age and height. The number of daily steps was estimated with a pedometer. Receiver operating curves were constructed and the area under the curve, sensitivity, specificity and 95% confidence interval (CI) were calculated, with analyzes separated by sex. The prevalence of high BP was 27.8%. Step count was a predictor of high BP in both boys (accuracy = 0.55; 95%CI: 0.51-0.60) and girls (accuracy = 0.58; 95%CI: 0.54-0.62). The cut-off points with the best balance between sensitivity and specificity were 14,228 steps for boys and 10,796 for girls. Pedometer-de-termined daily step count was a predictor of high BP in the children and adolescents studied. In practical terms, the use of 14,000 and 11,000 steps per day is recommended to discriminate high BP in young boys and girls, respectively. These findings could be useful to support actions designed to cope with high BP in childhood and adolescence

ABSTRACT

O objetivo da pesquisa foi investigar fatores de risco à hipertensão de jaleco branco entre pacientes adultos submetidos a cirurgia oral, particularmente a ansiedade odontológica. Trata-se de um estudo de caso- -controle pareado aninhado em estudo transversal realizado na Universidade Federal de Campina Grande e Faculdades Integradas de Patos, Paraíba, Brasil. Os pacientes tiveram suas pressões aferidas e classificadas de acordo com as V Diretrizes Brasileiras de Hipertensão Arterial (2007) e em seguida foram divididos em dois grupos: hipertensos (casos) e normotensos (controles). Os voluntários dos casos (n = 34) e dos controles (n = 136) foram emparelhados (1: 4) por gênero, faixa etária e escolaridade. Os mesmos responderam uma Escala de Ansiedade de Corah. A hipertensão de jaleco branco foi a variável dependente e a ansiedade odontológica foi a variável independente de interesse. A frequência de visitas ao dentista foi analisada como variável confusa. A análise descritiva, a regressão logística condicional bivariada e multivariada foram utilizadas como testes estatísticos com um nível de significância de 5%. Verificou-se que os pacientes ansiosos foram 11.052 vezes mais propensos à elevação da pressão arterial do que aqueles que não relataram ansiedade (IC 95%: 1.778 ­ 8.818). Os pacientes que nunca visitaram o dentista ou que o fizeram havia mais de dois anos tiveram 2,971 vezes mais chance de ter elevação da pressão arterial (IC 95%: 1,36 ­ 4,75). Conclui-se que ansiedade odontológica influencia a elevação da pressão arterial durante as cirurgias orais menores


The aim of this research was to investigate risk factors for white coat hypertension among adult patients undergoing oral surgery, particularly dental anxiety. This is a matched case-control study nested in a cross--sectional study conducted at the Universidade Federal de Campina Grande and Faculdades Integradas de Patos, Paraíba, Brazil. Patients had their blood pressure checked and classified according to the V Brazilian Guidelines for Hypertension (2007) and then divided into two groups: hypertensive (cases) and normotensive (controls). The volunteers of the cases (n = 34) and the controls (n = 136) were matched (1: 4) by gender, age group and schooling. They answered a Corah Anxiety Scale. White coat hypertension was the dependent variable and dental anxiety was the independent variable of interest. The frequency of visits to the dentist was analyzed as a confounding variable. The descriptive analysis, bivariate and multivariate conditional logistic regression were used as statistical tests with a significance level of 5%. It was found that anxious patients were 11,052 times more likely to raise blood pressure than those who did not report anxiety (95% CI: 1,778 - 8,818). Patients who never visited the dentist or who had been dentist for more than two years had 2,971 times more chance of having blood pressure elevation (95% CI: 1.36 - 4.75). It is concluded that dental anxiety influences elevation of blood pressure during minor oral surgeries.

ABSTRACT

RESUMEN Existe limitada evidencia de la asociación entre actividad física ocupacional y síndrome metabólico. Esto es importante ya que una gran parte del día cotidiano se gasta en el trabajo, el cual es mayormente sedentario. El objetivo del presente estudio fue evaluar la asociación entre niveles de actividad física ocupacional y la presencia de síndrome metabólico. Método: Análisis de datos secundarios usando información de un estudio poblacional en cinco estratos geográficos del Perú. La variable dependiente fue síndrome metabólico definido según consenso internacional; la exposición fue el auto-reporte de actividad física ocupacional (alto, moderado, bajo). Se usaron modelos de regresión de Poisson reportándose razones de prevalencia (RP) e intervalos de confianza al 95% (IC95%). Resultados principales: Datos de 4029 individuos fueron analizados, edad promedio 42,1 años (DE: 15,3) y 2013 (50,0%) fueron mujeres. Un total de 1011 (25,1%; IC95%: 23,8%-26,5%) sujetos presentaban síndrome metabólico. El modelo multivariable mostró asociación entre actividad física ocupacional y síndrome metabólico: comparado con los que reportaron altos niveles de actividad física, aquellos con actividad física moderada y baja tenían RP= 1,51 (IC95%: 1,25-1,81) y RP= 1,71 (IC95%: 1,42-2,06) veces más prevalencia de síndrome metabólico. La asociación fue más fuerte en los varones que en las mujeres (p= 0,001). Conclusiones: Nuestros hallazgos confirman la asociación entre niveles de actividad física ocupacional y la presencia de síndrome metabólico. Además 25% de la población de estudio cumplió con los criterios diagnósticos de síndrome metabólico.


ABSTRACT There is limited evidence about the association between work-related physical activity and metabolic syndrome. This is important as a great part of a usual day is related to work, and most of this is sedentary. The aim on this study was to assess the association between work-related physical activity and metabolic syndrome. Methods: A secondary analysis of data from a population-based study in five geographical strata in Peru. The outcome of interest was metabolic syndrome based on international consensus; exposure was the self-report of work-related physical activity (high, moderate, and low). Crude and adjusted Poisson regression models, with robust variance were used, from which prevalence ratios (PR) and 95% confidence intervals (95%CI) were reported. Results: Data from 4029 individuals were analyzed, mean age 42.1 (SD: 15.3) years, and 2013 (50.0%) were females. A total of 1011 (25.1%; 95%CI: 23.8%-26.5%) subjects had metabolic syndrome. The multivariable model evidenced an association between work-related physical activity and metabolic syndrome: compared to those reporting high levels of physical activity, those with moderate and low physical activity had 1.51 (95%CI: 1.25-1.81) and 1.71 (95%CI: 1.42-2.06) greater prevalence of metabolic syndrome. The association was stronger among males than females (p= 0.001). Conclusions: Our results confirm the association between work-related physical activity and the presence of metabolic syndrome. In addition, 25% of the study population had metabolic syndrome.

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
