Introduction: Propofol and midazolam are the main options for moderate sedation in clinical practice. In addition, these drugs are used to reduce intracranial pressure in cases of intracranial hypertension, and their use in these situations is guided by limited evidence. Objective: To compare the effects of propofol and midazolam on intracranial pressure wave morphology in moderate sedation in patients undergoing upper digestive endoscopy. Methods: Sixty patients were included in this study, being divided into two groups, propofol and midazolam group. Intracranial pressure was monitored during and after upper digestive endoscopy, using non-invasive monitoring equipment developed by the company Brain4care. Arterial pressure was measured before and after the exam. Results: The propofol group had lower intracranial pressure (p=0.037) during moderate sedation compared to intracranial pressure after endoscopy and a significant decrease in systolic (p=0.0001) and diastolic pressure (p=0.001) after sedation. Midazolam, on the other hand, reduced systolic pressure (p=0.001), but didn't change the other parameters after the procedure. There wasn't a significant difference between the propofol and midazolam groups. Conclusion: There was no significant difference between the groups studied, however, analyses within the propofol and midazolam groups indicate that propofol, but not midazolam, causes changes in intracranial pressure in moderate sedation.

Introducción: El edema agudo del pulmón es una enfermedad frecuente en los pacientes que se presentan en los servicios de urgencias. Objetivo: Caracterizar a los pacientes con edema agudo del pulmón en el servicio de urgencias. Método: Se realizó un estudio descriptivo y transversal en 37 pacientes con edema agudo del pulmón, que asistieron al cuerpo de guardia del Hospital Clinicoquirúrgico Docente Dr. Joaquín Castillo Duany de Santiago de Cuba, desde enero a noviembre de 2019. Las variables estudiadas fueron edad, sexo, estado al egreso y uso de la ventilación no invasiva. Resultados: No hubo diferencias entre ambos sexos, predominaron los mayores de 60 años, que padecían de hipertensión arterial. Se comprobó el poco uso de la ventilación no invasiva o invasiva. Conclusiones: El edema agudo del pulmón es más frecuente en pacientes mayores de 60 años, sin distinción de sexo. La mayoría lo presenta relacionado con la hipertensión arterial y existe un escaso uso de la ventilación no invasiva en estos casos.
Introduction: Acute pulmonary edema is a frequent disease among patients in emergency services. Objective: To characterize patients with acute pulmonary edema who attended the emergency services. Methods: A descriptive and cross-sectional study of 37 patients with acute pulmonary edema who attended the emergency services of Dr. Joaquín Castillo Duany Teaching Clinical Surgical Hospital in Santiago de Cuba was carried out, from January to November 2019. The studied variables were age, sex, alive or dead when discharged, noninvasive ventilation usage. Results: There were no differences between the sexes; there was a prevalence of patients older than 60 years of age, who suffered from hypertension. It was demonstrated low noninvasive or invasive ventilation usage. Conclusions: Acute pulmonary edema is more frequent among patients older than 60 years of age in both sexes. Most of the patients suffered from hypertension and there was a deficit in the implementation of noninvasive ventilation in these cases.

Objective:To study the early predictors of refractory septic shock (RSS) in neonates.Methods:From July 2020 to December 2021, clinical data of neonates with septic shock admitted to the Neonatal Department of our hospital were retrospectively reviewed. According to the maximum septic shock score (SSS) during clinical course, the neonates were assigned into RSS group and non-RSS group. Perinatal data, laboratory results and hemodynamic parameters at diagnosis were compared between the two groups. Multiple logistic regression analysis was used to identify independent risk factors of RSS and septic shock-related death. Receiver operating characteristic (ROC) curve was constructed to evaluate the early predictors of poor prognosis.Results:A total of 130 neonates were enrolled, including 54 in RSS group and 76 in non-RSS group. Compared with the non-RSS group, the RSS group had significantly lower pH, base excess (BE), stroke volume index (SVI), cardiac output (CO) and cardiac index (CI).Meanwhile, the RSS group had significantly higher mean arterial pressure (MAP) to CI ratio (MAP/CI) and SSS [including bedside SSS (bSSS), computed SSS (cSSS) and modified version of cSSS (mcSSS)] (all P<0.05). Multiple logistic regression analysis showed that increased MAP/CI was an independent predictor of RSS. The cut-off value of MAP/CI was 11.6 [sensitivity 62%, specificity 87%, positive predictive value (PPV) 79% and negative predictive value (NPV) 77%], with an area under the curve (AUC) of 0.734. Increased mcSSS was an independent predictor of septic shock-related death. The cut-off value of mcSSS was 5.8 (sensitivity 83%, specificity 72%, PPV 21% and NPV 97%), with an AUC of 0.845. Conclusions:Increased MAP/CI (≥11.6) and mcSSS (≥5.8) may be early predictors of RSS and septic shock-related death in neonates.

ABSTRACT Introduction: The Pilates method (PM) combines slow-deep breathing with strengthening and stretching exercises. However, it has been proposed as a method of physical conditioning for several decades and only recently aroused academic/scientific interest, with few reports of the effects of this intervention in hypertensive patients. Objective: to compare PM to aerobic training (AT) effects on hypertensive subjects' blood pressure (BP), functional capacity and autonomic balance. Methods: Twenty-four hypertensive subjects were randomly allocated into two groups: ATG performed three 40 min sessions/week, moderate intensity (40-70% of reserve HR), and PMG performed two 60 min sessions/week; both during the same eight weeks period. Blood pressure (casual and for 24 hours), 6-minute walking test (6-MWT) and autonomic balance were evaluated before and after intervention. Results: There was a reduction on systolic BP (SBP, p=0.007), diastolic (p=0.032) and mean blood pressure (MBP, p=0.016), measured on 24h, on PMG. There was also a 24h SBP reduction on ATG (p=0.021). The PMG had a greater reduction on 24h SBP (-3.4 mmHg, 95% CI -6.6 to -0.2) and MBP (-3.3 mmHg, 95% CI -6.3 to -0.3) than the ATG. ATG held a longer distance in 6-MWT. Casual BP and autonomic balance had no difference. Conclusion: This PM protocol was superior to AT on BP monitored for 24 hours in hypertensive subjects, but AT was better for functional capacity. The eight weeks of training were not enough to change the autonomic balance. Level of Evidence: I; High-quality randomized clinical trial with or without statistically significant difference, but with narrow confidence intervals.
RESUMEN Introducción: el método Pilates (MP) combina la respiración lenta-profunda con ejercicios de fortalecimiento y estiramiento. Aunque se ha propuesto como un método de acondicionamiento físico durante varias décadas, solo recientemente despertó interés académico/científico, con pocos reportes de los efectos de esta intervención en pacientes hipertensos. Objetivo: comparar los efectos del MP con el entrenamiento aeróbico (EA) sobre la presión arterial (PA), la capacidad funcional y el equilibrio autónomo en sujetos hipertensos. Métodos: Veinticuatro sujetos hipertensos fueron asignados aleatoriamente en dos grupos: GEA realizó tres sesiones de 40 min/semana, intensidad moderada (40-70% de la FC de reserva), y GMP realizó dos sesiones de 60 min/semana; ambos durante el mismo período de 8 semanas. La presión arterial (casual y durante 24 horas), la prueba de marcha de 6 minutos y el equilibrio autonómico se evaluaron antes y después de la intervención. Resultados: Hubo una reducción de la PA sistólica (PAS, p = 0,007), diastólica (p = 0,032) y presión arterial media (PAM, p = 0,016), medida a las 24 h, en GMP. También hubo una reducción de PAS en 24 h en GEA (p = 0,021). El GMP tuvo una mayor reducción en la PAS de 24 h (-3,4 mmHg, CI del 95%: -6,6 a -0,2) y la PAM (-3,3 mmHg, CI del 95%: -6,3 a -0,3) que la GEA. GEA mantuvo una mayor distancia en la prueba de marcha de 6 minutos. La PA casual y el equilibrio autónomo no tuvieron diferencias. Conclusión: Este protocolo de MP fue superior al EA en la PA monitoreada durante 24 horas en sujetos hipertensos, pero el EA fue mejor para la capacidad funcional. Las ocho semanas de entrenamiento no fueron suficientes para cambiar el equilibrio autonómico. Nivel de Evidencia: I; Estudio clínico aleatorizado de alta calidad con o sin diferencia estadísticamente significativa, pero con intervalos de confianza estrechos.
RESUMO Introdução: O método Pilates (MP) combina respiração lenta e profunda com exercícios de fortalecimento e alongamento. Embora tenha sido proposto como método de condicionamento físico por várias décadas, só recentemente despertou-se o interesse acadêmico/científico, com poucos relatos dos efeitos dessa intervenção em hipertensos. Objetivos: comparar os efeitos do MP com o treinamento aeróbio (TA) sobre a pressão arterial (PA), capacidade funcional e equilíbrio autonômico em hipertensos. Métodos: Vinte e quatro hipertensos foram alocados aleatoriamente em dois grupos: O grupo GTA realizou três sessões de 40 min/semana, intensidade moderada (40-70% da FC de reserva), e o grupo GMP, que realizou duas sessões de 60 min/semana; ambos durante o mesmo período de 8 semanas. A pressão arterial (casual e após 24 horas), o teste de caminhada de 6 minutos (TC6) e o equilíbrio autonômico foram avaliados antes e depois da intervenção. Resultados: Houve redução da PA sistólica (PAS, p = 0,007), diastólica (p = 0,032) e da pressão arterial média (PAM, p = 0,016), medida em 24h, sem GMP. Também houve redução da PAS em 24h no GTA (p = 0,021). O GMP teve uma redução maior em 24h PAS (-3,4 mmHg, IC 95% -6,6 a -0,2) e PAM (-3,3 mmHg, IC 95% -6,3 a -0,3) do que o GTA. O GTA manteve uma maior distância no TC6. A PA casual e o equilíbrio autonômico não apresentaram diferenças estatísticas. Conclusão: Este protocolo de MP foi superior ao TA na PA monitorada por 24 horas em hipertensos, porém o TA foi superior para a capacidade funcional. As oito semanas de treinamento não foram suficientes para alterar o equilíbrio autonômico. Nível de Evidência: 1; Estudo clínico randomizado de alta qualidade com ou sem diferença estatisticamente significativa, mas com intervalos de confiança estreitos.

Abstract Introduction: Patients with end-stage renal disease often face a challenging routine of hemodialysis, dietary restrictions, and multiple medications, which can affect their hemodynamic function. Home-based, safe, and nonpharmacological approaches such as transcranial direct current stimulation (tDCS) should be combined with conventional treatment. Objective: To assess the safety and feasibility of tDCS on blood pressure and heart rate in patients with end-stage renal disease undergoing hemodialysis. Method: This is a parallel, randomized, sham-controlled trial. Patients undergoing hemodialysis for more than three months were included. The patients received ten non-consecutive 2mA tDCS sessions on the primary motor cortex . Each session lasted 20 minutes. At baseline and after each of the ten sessions, blood pressure and heart rate of the patients were measured hourly for four hours. Results: Thirty patients were randomized to the active or sham group. The mean difference between the groups was calculated as the mean value of the sham group minus the mean value of the active group. Despite there were no statistical changes for all outcomes considering all 10 sessions, we found differences between groups for systolic -10.93 (-29.1;7.2), diastolic -3.63 (-12.4; 5.1), and mean blood pressure -6.0 (-16.3; 4.2) and hear rate 2.26 (-2.5; 7.1). No serious adverse events were found. The active group showed higher blood pressure values at all points, while heart rate was lower in the active group. Conclusion: tDCS is safe and feasible for patients with end-stage renal disease undergoing hemodialysis. Future studies should investigate whether tDCS could potentially induce a hypotensive protective effect during hemodialysis.
Resumo Introdução: Pacientes com doença renal em estágio terminal (DRET) geralmente enfrentam uma rotina desafiadora de hemodiálise, restrições alimentares e diversos medicamentos, podendo afetar sua função hemodinâmica. Abordagens domiciliares, seguras e não farmacológicas, como a estimulação transcraniana por corrente contínua (ETCC), devem ser combinadas com tratamento convencional. Objetivo: Avaliar segurança e viabilidade da ETCC na pressão arterial e frequência cardíaca em pacientes com DRET em hemodiálise. Método: Estudo paralelo, randomizado, controlado por placebo. Foram incluídos pacientes em hemodiálise por mais de três meses. Os pacientes receberam dez sessões não consecutivas de ETCC de 2mA no córtex motor primário. Cada sessão durou 20 minutos. No início do estudo e após cada uma das dez sessões, a pressão arterial e frequência cardíaca dos pacientes foram medidas a cada hora durante quatro horas. Resultados: Trinta pacientes foram randomizados para grupo ativo ou sham. A diferença média entre grupos foi calculada como valor médio do grupo sham menos valor médio do grupo ativo. Apesar de não haver alterações estatísticas para todos os desfechos considerando as 10 sessões, encontramos diferenças entre os grupos para pressão arterial sistólica -10,93 (-29,1; 7,2), diastólica -3,63 (-12,4; 5,1) e média -6,0 (-16,3; 4,2) e frequência cardíaca 2,26 (-2,5; 7,1). Não encontramos eventos adversos graves. O grupo ativo apresentou valores maiores de pressão arterial em todos os pontos, enquanto a frequência cardíaca foi menor no grupo ativo. Conclusão: ETCC é segura e viável para pacientes com DRET submetidos à hemodiálise. Estudos futuros devem investigar se a ETCC pode potencialmente induzir um efeito hipotensor protetor durante a hemodiálise.

Las Ciencias Médicas y Biológicas requieren, prioritariamente, que la investigación y la experimentación sean desarrolladas sobre organismos completos (los modelos animales). Su utilización ha permitido desarrollar innumerables ensayos preclínicos para evaluar los mecanismos patógenos y terapéuticos de diversas enfermedades, así como el estudio de las causas, naturaleza y cura de múltiples desórdenes de la salud humana. En este trabajo se muestra una panorámica general de los biomodelos de hipertensión arterial donde se describen: conceptos, características, origen, importancia, utilidad y procedimientos experimentales durante su fase de inducción. También se pondera la justificación de los biomodelos empleados en los estudios preclínicos de esta enfermedad. De igual forma, se describen los antecedentes para medir las alteraciones, las técnicas y los métodos directos e indirectos de medición de la presión arterial, la cual fue provocada experimentalmente en los animales de laboratorio para realizar los estudios de hipertensión humana.
Medical and biological sciences require, as a priority, that research and experimentation be carried out on complete organisms (animal models). Its use has allowed the development of innumerable preclinical tests to evaluate pathogenic and therapeutic mechanisms of various diseases, as well as to study the causes, nature and cure of multiple human health disorders. In this work, we show a general overview of arterial hypertension biomodels where concepts, characteristics, origin, importance, utility and experimental procedures during their induction phase are described. The justification of the biomodels used in preclinical studies of this disease is also considered. Antecedents are also described to measure alterations, techniques and direct and indirect methods of measurement of arterial pressure, which was provoked experimentally in the laboratory animals to carry out the studies of human hypertension.

La obesidad es una acumulación anormal y excesiva de grasa perjudicial para la salud con impacto negativo en la calidad de vida, asociada comorbilidades como la hipertensión arterial. En 2015 se estimaba 603,7 millones de adultos con obesidad en el mundo. Los datos de NHANES consideran un aumento progresivo de obesidad y sobrepeso en los últimos 30 años que paso de 22,9% a 42,4%. En Ecuador 6 de cada 10 personas tienen sobrepeso u obesidad. La hipertensión en la obesidad está determinada con mayor frecuencia por el envejecimiento vascular acelerado por procesos inflamatorios, estrés oxidativo y resistencia a la insulina. Las modificaciones en el estilo de vida determinan que por cada 1 kg de pérdida de peso disminuye a corto plazo 1 mmHg de la presión arterial sistólica. La cirugía bariátrica posee un impacto en la pérdida de peso y los factores cardiovasculares. Los registros epidemiológicos han demostrado una relación lineal directa entre la obesidad y la presión arterial: a medida que aumenta el peso, aumenta la presión arterial. De la misma manera, el efecto de reducción de la presión arterial sobre la pérdida de peso parece ser lineal: a mayor pérdida de peso mayor disminución de la presión arterial.
Obesity is an abnormal and excessive accumulation of fat that is detrimental to health with a negative impact on quality of life, associated with comorbidities such as arterial hypertension. In 2015, it was estimated that there were 603.7 million obese adults in the world. The NHANES data consider a progressive increase in obesity and overweight in the last 30 years, from 22.9% to 42.4%. In Ecuador 6 out of 10 people are overweight or obese. Hypertension in obesity is most often determined by vascular aging accelerated by inflammatory processes, oxidative stress, and insulin resistance. Changes in lifestyle determine that for every 1 kg of weight loss, there is a short-term reduction of 1 mmHg in systolic blood pressure. Bariatric surgery has an impact on weight loss and cardiovascular factors. Epidemiological records have shown a direct linear relationship between obesity and blood pressure: as weight increases, blood pressure increases. Similarly, the effect of blood pressure reduction on weight loss appears to be linear: the greater the weight loss, the greater the decrease in blood pressure.

ABSTRACT Objective: To explain the rationale and protocol of the methods and analyses to be used in the LIVER-PAM randomized clinical trial, which seeks to understand whether a higher mean arterial pressure is capable of reducing the incidence of renal dysfunction postoperatively after liver transplantation. Methods: LIVER-PAM is an open-label, randomized, controlled, singlecenter clinical trial. Patients randomized to the intervention group will have a mean arterial pressure of 85 - 90mmHg in the initial 24 hours of postoperative management, while patients in the control group will have a mean arterial pressure of 65 - 70mmHg in the same period. A sample of 174 patients will be required to demonstrate a 20% reduction in the absolute incidence of renal dysfunction, with a power of 80% and an alpha of 0.05. Conclusion: If a 20% reduction in the absolute incidence of renal dysfunction in the postoperative period of liver transplantation is achieved with higher target mean arterial pressure in the first 24 hours, this would represent an inexpensive and simple therapy for improving current outcomes in the management of liver transplant patients. ClinicalTrials.gov Registry:NCT05068713
RESUMO Objetivo: Explicitar o racional e o protocolo de métodos e análises a serem utilizadas no ensaio clínico randomizado LIVER-PAM, que busca entender se um nível mais alto de pressão arterial média é capaz de reduzir a incidência de disfunção renal no pós-operatório de transplante hepático. Métodos: O LIVER-PAM é um estudo clínico randomizado, controlado, unicêntrico e aberto. Pacientes randomizados para o grupo intervenção terão como alvo de pressão arterial média 85 - 90mmHg nas 24 horas iniciais do manejo pós-operatório, enquanto pacientes do grupo controle terão como alvo de pressão arterial média 65 - 70mmHg no mesmo período. Uma amostra de 174 pacientes será necessária para demonstrar redução de 20% na incidência absoluta de disfunção renal, com poder de 80% e alfa de 0,05. Conclusão: Se a redução de 20% da incidência absoluta de disfunção renal no pós-operatório de transplante hepático for obtida com alvos maiores de pressão arterial média nas primeiras 24 horas, o manejo do paciente nesse cenário encontraria uma terapia barata e simples para a melhoria dos desfechos atuais.

Resumo Fundamento O aumento de hipertensão em crianças e adolescentes tem atraído a atenção da comunidade científica, especialmente por sua associação com a epidemia da obesidade. Objetivos Descrever a incidência de hipertensão e sua relação com o perfil cardiometabólico e genético em crianças e adolescentes de uma cidade do sul do Brasil em um período de três anos. Métodos Este estudo longitudinal acompanhou 469 crianças e adolescentes com idade entre 7 e 17 anos (43,1% do sexo masculino), avaliados em dois momentos. Avaliamos pressão arterial sistólica (PAS), pressão arterial diastólica (PAD), circunferência da cintura (CC), índice de massa corporal (IMC), porcentagem de gordura corporal (%GC), perfil lipídico, glicemia, aptidão cardiorrespiratória (APCR), e polimorfismo rs9939609 (gene FTO ) ( fat mass and obesity - associated gene ). A incidência cumulativa da hipertensão foi calculada, e realizada regressão logística multinominal. A diferença estatística foi estabelecida em p<0,05. Resultados Após três anos, a incidência de hipertensão foi de 11,5%. Indivíduos com sobrepeso e indivíduos obesos apresentaram maior probabilidade de se tornarem indivíduos classificados como borderline para hipertensão (sobrepeso OR: 3,22; IC95%: 1,08-9,55; obesidade OR: 4,05; IC95%: 1,68-9,75), e indivíduos obesos apresentaram maior probabilidade de se tornarem hipertensos (obesidade OR: 4,84; IC95%: 1,57-14,95). Valores de CC e de %GC considerados de alto risco foram associados com o desenvolvimento de hipertensão (OR: 3,41; IC95%: 126-9,19; OR: 2,49, IC95%: 1,08-5,75, respectivamente). Conclusão Encontramos uma incidência de hipertensão em crianças e adolescentes mais alta em comparação a estudos anteriores. Indivíduos com valores mais altos de IMC, CC e %GC no baseline apresentaram maior probabilidade de desenvolverem hipertensão, sugerindo a importância da adiposidade no desenvolvimento de hipertensão, mesmo em uma população tão jovem.
Abstract Background The increase of hypertension in children and adolescents has attracted the attention of the scientific community largely due to its association with the obesity epidemic. Objectives To describe the incidence of hypertension and its relationship with the cardiometabolic and genetic profile in children and adolescents from a city in southern Brazil in a three-year period. Methods This longitudinal study followed 469 children and adolescents, aged 7-17 years old (43.1% boys), assessed at two-time points. We evaluated systolic and diastolic blood pressures (SBP and DBP), waist circumference (WC), body mass index (BMI), body fat percentage (%BF), lipid profile, glucose, cardiorespiratory fitness (CRF), and rs9939609 Polymorphism ( FTO ). Cumulative incidence of hypertension was calculated, and multinomial logistic regression was conducted. The statistical significance was established as p < 0.05. Results After three years, the incidence of hypertension was 11.5%. Overweight or obese individuals were more likely to become borderline hypertensive (overweight OR: 3.22, 95% CI: 1.08-9.55; obesity OR: 4.05, 95% CI: 1.68-9.75), and obese individuals were more likely to become hypertensive (obesity OR: 4.84, 95% CI: 1.57-14.95). High-risk WC and %BF values were associated with hypertension development (OR: 3.41, 95% CI: 1.26-9.19; OR: 2.49, 95% CI: 1.08-5.75, respectively). Conclusions We found a higher incidence of hypertension in children and adolescents as compared with previous studies. Individuals with higher values of BMI, WC and %BF at baseline were more likely to develop hypertension, suggesting the importance of adiposity in the development of hypertension even in such a young population.

Objective:To investigate the efficacy of phenolamine in the treatment of sepsis-induced myocardial dysfunction and its effect on cardiac function, myocardial injury index, and hemodynamics in patients.Methods:The clinical data of 79 patients with sepsis-induced myocardial dysfunction who received treatment in Huangshi Central Hospital, Edong Healthcare Group from February 2017 to February 2020 were retrospectively analyzed. These patients were divided into a control group (without phenolamine treatment, n = 41) and an observation group (with phenolamine treatment, n = 38) according to whether they received phenolamine treatment or not. Clinical efficacy, cardiac function, myocardial injury index, and hemodynamic index pre- and post-treatment were compared between the two groups. Results:There was no significant difference in 28-day mortality rate between the two groups ( P > 0.05). Intensive care unit length of stay and mechanical ventilation duration in the observation group were (9.33 ± 3.52) days and 83.00 (28.50, 138.00) hours, which were significantly shorter than (12.17 ± 4.15) days and 111.00 (47.50, 169.00) hours in the control group ( t = 3.26, Z = -2.27, both P < 0.05). The response rate in the observation group was significantly higher than that in the control group [81.58% (31/38) vs. 60.98% (25/41), χ2 = 4.05, P < 0.05]. After 7 days of treatment, the left ventricular ejection fraction in each group was significantly increased, and the left ventricular end-diastolic diameter and left ventricular end-systolic diameter in each group were significantly decreased compared with before treatment (all P < 0.05). After 7 days of treatment, the left ventricular ejection fraction in the observation group was significantly higher than that in the control group ( t = 3.29, P < 0.05), and left ventricular end-diastolic diameter and left ventricular end-systolic diameter were significantly lower than those in the control group ( t = 5.94, 11.21, both P < 0.05). N-terminal pro-brain natriuretic peptide and cardiac troponin I levels in each group were significantly decreased with time (both P < 0.05). At 24 and 72 hours and 7 days after treatment, N-terminal pro-brain natriuretic peptide and cardiac troponin I levels in the observation group were significantly lower than those in the control group (both P < 0.05). After 7 days of treatment, heart rate in each group decreased significantly compared with that before treatment (both P < 0.05), mean arterial pressure, cardiac index, and stroke output index in each group increased significantly compared with those before treatment (all P < 0.05). After 7 days of treatment, heart rate in the observation group was significantly lower than that in the control group ( t = 4.90, P < 0.05), and mean arterial pressure, cardiac index, and stroke output index in the observation group were significantly higher than those in the control group ( t = 4.37, 3.23, 6.01, all P < 0.05). Conclusion:Phentolamine can improve hemodynamics, reduce myocardial injury and improve cardiac function in patients with sepsis-induced myocardial dysfunction.

Objective:To investigate the clinical efficacy of combined spinal and epidural anesthesia with isobaric bupivacaine in older adult patients undergoing artificial femoral head replacement.Methods:The clinical data of 50 older adult patients who underwent artificial femoral head replacement in Zhuji Third People's Hospital between January 2016 and January 2020 were retrospectively analyzed. The patients were divided into a control group ( n = 22) and a combined anesthesia group ( n = 28) according to different anesthesia methods. The control group was subjected to epidural anesthesia with bupivacaine. The combined anesthesia group underwent combined spinal and epidural anesthesia with isobaric bupivacaine. The excellent and good rate of anesthesia as well as heart rate and mean arterial pressure measured before and 10 minutes after anesthesia, at 1 hour of surgery and at the end of surgery were compared between the two groups. Time to anesthesia onset and time to block completion were recorded in each group. Results:The excellent and good rate of clinical efficacy in the combined anesthesia group was significantly higher than that in the control group [85.71% (24/28) vs. 59.09% (13/22), χ2 = 4.54, P < 0.05]. There were no significant differences in heart rate and mean arterial pressure between the two groups before and 10 minutes after anesthesia, at 1 hour of surgery and at the end of surgery ( t = 0.83, 0.60, 1.13, 1.21; 0.98, 0.60, 0.85, 0.88, P > 0.05). The time to anesthesia onset and the time to block completion in the combined anesthesia group were shorter than those in the control group ( t = 4.99, 2.29, both P < 0.05). Conclusion:Combined spinal and epidural anesthesia with isobaric bupivacaine can increase the excellent and good rate of anesthesia effects and has no obvious effect on hemodynamics in patients undergoing artificial femoral head replacement. Combined spinal and epidural anesthesia takes a shorter time to anesthesia onset and a shorter time to block completion than spinal or epidural anesthesia.

Resumo Fundamento A mensuração indireta da pressão sanguínea (PS) é sabidamente influenciada por diversos fatores como técnica, observador e equipamento, mas a influência da composição do braço ainda não foi investigada. Objetivo Identificar a influência da gordura do braço sobre a medida indireta da pressão sanguínea, utilizando modelos de inferência estatística e machine learning. Métodos Estudo transversal, com 489 adultos jovens saudáveis de 18 a 29 anos de idade. Foram medidos comprimento (COB), circunferência do braço (CB) e índice de gordura do braço (IGB). A PS foi mensurada em ambos os braços, simultaneamente. Os dados foram processados utilizando-se Python 3.0 e pacotes específicos para análise descritiva, regressão e clusterização. Um nível de significância de 5% foi adotado para todos os cálculos. Resultados A PS e as medidas antropométricas foram diferentes entre os hemicorpos. A pressão sanguínea sistólica (PAS), COB, e IGB foram maiores no braço direito (BD), enquanto CB foi similar em comparação ao braço esquerdo. COB e CB apresentaram correlação positiva com a PAS. Conforme o modelo de regressão, para determinado valor de CB e COB, a leitura da PAS poderá ter uma redução média de 1,80 mmHg no BD, e 1,62 mmHg no braço esquerdo, a cada 10% de aumento na IGB. A clusterização corroborou os resultados da regressão. Conclusão Foi encontrada uma influência significativa do IGB sobre a leitura da PS. A PAS teve correlação positiva com COB e CB, e correlação negativa com IGB, o que sugere a necessidade de mais investigações sobre a relação da PS com as frações de gordura e músculo do braço.
Abstract Background The indirect measurement of blood pressure (BP) is known to be influenced by many factors such as the technique, observer, and equipment; however, the influence of arm composition has not been investigated yet. Objective To identify the influence of arm fat on the indirect measurement of blood pressure using statistical inference and machine learning models. Methods Cross-sectional study, with 489 healthy young adults aged from 18 to 29 years old. Measurements of arm length (AL), arm circumference (AC) and arm fat index (AFI) were taken. BP was measured in both arms simultaneously. Data were processed using Python 3.0 and its specific packages for descriptive analysis, regression and cluster analysis. Significance levels: 5% for all calculations. Results BP and anthropometric measurements were different between the hemi-bodies. In the right arm, systolic blood pressure (SBP), AL and AFI were higher, while AC was similar compared with the left arm. AL and AC showed positive correlation with SBP. According to the regression model, for a fixed value of AC and AL, SBP readings could be reduced by a mean of 1.80 mmHg in the right arm, and 1.62 mmHg in the left arm for every 10% increase in AFI. Clustering analysis corroborated the regression results. Conclusion There was a significant influence of AFI on BP readings. SBP had a positive correlation with AL and AC, and a negative correlation with AFI, suggesting the need for further investigations on the relationship between BP and percentages of arm muscle and fat.

Abstract Background Controlling blood pressure and glycemic levels is a challenge that requires innovative solutions. Objective To assess the feasibility of implementing a text message intervention among low-income primary care patients, as well as to assess self-reported behavioral change. Methods A set of 200 text messages was developed on healthy eating, physical activity, adherence, and motivation. Participants from Vale do Mucuri, MG, Brazil diagnosed with diabetes or hypertension or undergoing screening for those diseases, received 5 to 8 messages per week for 6 months. They answered a questionnaire to report their satisfaction and behavioral changes. Results Of the 136 patients, 117 (86.0%) answered the questionnaire. Most reported that the messages were very useful (86.3%), easy to understand (90.6%), and were very helpful for behavioral change (65.0%); 84.6% reported that they had started eating healthier. The most frequent reported lifestyle changes were: improved diet quality (85.5%), reduced portions (65.8%), and weight loss (56.4%). The majority of patients shared the messages (60.7%) with family or other acquaintances, considered the number of messages to be adequate (89.7%) and would recommend the program to others (95.7%). Conclusion An intervention based on text messages to promote behavioral change in patients with hypertension or diabetes in primary care is feasible in low-resource settings. Future studies are needed to assess the program's long-term effects on clinical outcomes.

Resumo 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.
Abstract 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.

Resumo Fundamento A associação entre resposta exagerada da pressão arterial sistólica ao exercício (REPASE) e isquemia miocárdica é controversa e pouco estudada em indivíduos com síndrome coronariana crônica estabelecida ou suspeita. Objetivo Verificar a relação entre isquemia miocárdica e REPASE em indivíduos submetidos à ecocardiografia sob estresse físico (EEF). Métodos Trata-se de estudo transversal com 14.367 indivíduos submetidos à EEF, de janeiro de 2000 a janeiro de 2022, divididos em dois grupos: G1 - composto por pacientes cuja pressão sistólica de pico apresentou incremento ≥ 90 mmHg (valor correspondente ao percentil 95 da população estudada) -, e G2 - formado por indivíduos que não apresentaram resposta hipertensiva exagerada. Os grupos foram comparados mediante os testes t de Student e qui-quadrado. Foram considerados significativos os valores de p < 0,05. Realizou-se, também, regressão logística para identificação de fatores de risco independentes para isquemia miocárdica, REPASE, queixa de precordialgia típica prévia ao exame e angina durante o teste. Resultados Dos 14.367 pacientes, 1.500 (10,4%) desenvolveram REPASE e 7.471 (52,0%) eram do sexo feminino. Os percentuais de queixa prévia de precordialgia típica, angina durante o teste e isquemia miocárdica dos pacientes com REPASE foram de 5,8%, 2,4% e 18,1% contra 7,4%, 3,9% e 24,2%, em indivíduos sem REPASE, respectivamente (p = 0,021, p = 0,004, p < 0,001). Na análise multivariada, a REPASE foi associada, independentemente, a uma menor probabilidade de isquemia miocárdica (odds ratio: 0,73; intervalo de confiança de 95%: 0,58 a 0,93; p = 0,009). Conclusão O incremento exagerado da pressão arterial sistólica durante a EEF pode ser um marcador de exclusão de isquemia miocárdica.
Abstract Background The association between exaggerated systolic blood pressure response to exercise (ESBPRE) and myocardial ischemia is controversial and little studied in patients with established or suspected chronic coronary syndrome. Objective To verify the relationship between myocardial ischemia and ESBPRE in patients undergoing exercise stress echocardiography (ESE). Methods This is a cross-sectional study with 14,367 patients undergoing ESE, from January 2000 to January 2022, divided into the following 2 groups: G1, composed of patients whose peak systolic pressure increased ≥ 90 mmHg (value corresponding to the 95th percentile of the study population), and G2, patients who did not demonstrate an exaggerated hypertensive response. The groups were compared using Student's t and chi-square tests. P values < 0.05 were considered significant. Logistic regression was also performed to identify independent risk factors for myocardial ischemia, ESBPRE, complaints of typical chest pain prior to the exam, and angina during the test. Results Of the 14,367 patients, 1,500 (10.4%) developed ESBPRE, and 7,471 (52.0%) were female. The percentages of previous complaints of typical chest pain, angina during the test, and myocardial ischemia in patients with ESBPRE were 5.8%, 2.4% and 18.1%, compared to 7.4%, 3.9%, and 24.2%, in patients without ESBPRE, respectively (p = 0.021,p = 0.004, p < 0.001). In multivariate analysis, ESBPRE was independently associated with a lower probability of myocardial ischemia (odds ratio: 0.73; 95% confidence interval: 0.58 to 0.93; p = 0.009). Conclusion Exaggerated increase in systolic blood pressure during ESE may be a marker for excluding myocardial ischemia.
