RESUMEN

Saliva measurements serve as a noninvasive tool for clinically monitoring newborns (NB) and children, a vulnerable population with promising potential for both research and clinical practice. Saliva acts as a repository for various inflammatory biomarkers involved in diverse biological functions. Particularly for children, it offers numerous advantages when compared to plasma and urine sampling. Nevertheless, there is a significant knowledge gap regarding detectable levels of cytokines in the saliva of newborns and children, as well as studies aiming to assess the relationship of this content with physiological and pathological processes. OBJECTIVES: To characterize the levels of 11 inflammatory mediators (IFNg, IL1b, IL2, IL4, IL6, IL8, IL10, IL12, IL17, TNF, and VEGF) in saliva samples from NB on the first and second day of hospitalization in the Neonatal Intensive Care Unit (NICU). METHOD: Exploratory study, descriptive, nested within a primary clinical, observational, and prospective study, conducted in the NICU of a public hospital in São Paulo, Brazil. Demographic data and vital signs were recorded in the clinical records of 90 NB, and five saliva samples from 5 NB were collected between the first and second day of life (D1-D2) at approximately 8-hr intervals (8-9 am, 4-5 pm, and 11-12 pm). Saliva samples were used for the measurement of 11 cytokines (IFNg, IL1b, IL2, IL4, IL6, IL8, IL10, IL12, IL17, TNF, and VEGF). RESULTS: Five NBs participated in this exploratory study, and the vital signs showed variability from the first (D1) to the second day (D2) of hospitalization, variability similar to that of the total population of the primary study. The presence and levels of the 11 cytokines were detected in the saliva samples, as well as a statistical correlation between 10 cytokines (IFNg, IL1b, IL2, IL4, IL6, IL10, IL12, IL17, TNF, and VEGF) and vital signs. CONCLUSIONS: The novelty of measuring inflammatory mediators in saliva samples from hospitalized NBs in the NICU is highlighted, providing support and new perspectives for the development of clinical and experimental research and an opportunity for developing and implementing new salivary biomarkers in different population segments.

RESUMEN

BACKGROUND: Virtual consultations have increased exponentially, but a limitation is the inability to assess vital signs (VS). This is particularly useful in patients with heart failure (HF) for titrating prognosis-modifying medication. This issue could potentially be addressed by a tool capable of measuring blood pressure (BP) and heart rate (HR) accurately, remotely, and conveniently. Mobile phones equipped with transdermal optical imaging technology could meet these requirements. OBJECTIVE: To evaluate the accuracy of a transdermal optical imaging-based app for estimating VS compared to clinical assessment in patients with HF. METHODS: A prospective cohort study included patients evaluated in an HF outpatient unit between February and April 2022. BP and HR were simultaneously assessed using the app and clinical examination (BP with an automated sphygmomanometer and HR by brachial palpation). Three measurements were taken by both the app and clinic for each patient, by two independent blinded physicians. RESULTS: Thirty patients were included, with 540 measurements of BP and HR. The mean age was 66 (± 13) years, 53.3% were male. The mean left ventricular ejection fraction was 37 ± 15, with 63.3% having previous hospitalizations for HF, and 63.4% in NYHA class II-III. The mean difference between the app measurement and its clinical reference measurement was 3.6 ± 0.5 mmHg for systolic BP (SBP), 0.9 ± -0.2 mmHg for diastolic BP (DBP), and 0.2 ± 0.4 bpm for HR. When averaging the paired mean differences for each patient, the mean across the 30 patients was 2 ± 6 mmHg for SBP, -0.14 ± 4.6 mmHg for DBP, and 0.23 ± 4 bpm for HR. CONCLUSION: The estimation of BP and HR by an app with transdermal optical imaging technology was comparable to non-invasive measurement in patients with HF and met the precision criteria for BP measurement in this preliminary study. The use of this new transdermal optical imaging technology provides promising data, which should be corroborated in larger cohorts.

ANTECEDENTES: Las consultas virtuales aumentaron exponencialmente, pero presentan como limitación la imposibilidad de valorar los signos vitales (SV), siendo especialmente útiles en los pacientes con insuficiencia cardiaca (IC) para titular medicación que modifica pronóstico. Este problema podría potencialmente solucionarse mediante una herramienta que pueda medir la presión arterial (PA) y frecuencia cardiaca (FC) de manera precisa, accesible y remota. Los teléfonos móviles equipados con tecnología de imágenes ópticas transdérmicas podrían cumplir con estos requisitos. OBJETIVO: Evaluar la precisión de una app basada en imagen óptica transdérmica para estimar SV en relación con la valoración clínica en pacientes con IC. MÉTODOS: Estudio de cohorte prospectivo, se incluyeron pacientes evaluados en una unidad ambulatoria de IC de febrero a abril del 2022. Se valoró simultáneamente la PA y FC mediante la app y el examen clínico (PA con un esfigmomanómetro automatizado y FC por palpación braquial). Se realizaron tres mediciones por app y clínica en cada paciente, por dos médicos independientes, encontrándose ciegos a los resultados. RESULTADOS: Se incluyeron 30 pacientes, con 540 mediciones de TA y de FC. Edad media de 66 (± 13) años, el 53.3% de sexo masculino. La fracción de eyección del ventrículo izquierdo media fue de 37 ± 15, con hospitalizaciones previas por IC el 63.3%, en CF II-III el 63.4%. La diferencia media entre la medición de la app y su medición de referencia clínica fue de 3.6 ± 0.5 mmHg para PA sistólica (PAS), 0.9 ± ­0.2 mmHg para PA diastólica (PAD) y 0.2 ± 0.4 lpm para FC. Cuando se promedian las diferencias medias emparejadas para cada paciente, la media entre los 30 pacientes es de 2 ± 6 mmHg para PAS, ­0.14 ± 4.6 mmHg para PAD y 0.23 ± 4 lpm para FC. CONCLUSIÓN: La estimación de PA y FC por una app con tecnología de imagen óptica transdérmica fue comparable a la medición no invasiva en pacientes con IC, y cumple los criterios de precisión de la medición de PA en este estudio preliminar. La utilización de esta nueva tecnología de imagen óptica transdérmica brinda datos prometedores, que deberán ser corroborados en cohortes de mayor tamaño.

RESUMEN

The aim of this study was to evaluate the vital signs related with different dental treatments, and correlate with demographic data and participants' anxiety level. This is a prospective clinical study with 60 participants, divided into 3 groups of dental procedures: (1) restorative treatment, (2) extractions and biopsies, and (3) gingival treatment. A level of anxiety questionnaire before dental procedure proposed by Corah's Dental Anxiety Scale was collected. Respiratory rate, systolic and diastolic pressure, temperature and oxygenation were measured before, during and after the procedures. 31 (51.7 %) women and 29 (48.3 %) men were included, with mean age of 41.75 years old. Most participants (50 %) were classified as very little anxious. Diastolic pressure before the procedure was higher for slightly anxious patients when compar ed with very little anxious patients (p=0.028). Systolic pressure before, during and after the procedure was higher for participan ts above 40 years old (p=0,001). Heart rate (p=0,050) and temperature (p=0,041) was higher before the restorative treatment. Anxiety can promote changes in vital signs in the dental environment. Vital signs, sex, age and level of anxiety do influence the blood pressure at different clinical moments. Dental procedures have association with variations in temperature, heart and respiratory rate.

El objetivo de este estudio fue evaluar los signos vitales relacionados con diferentes tratamientos dentales y correlacionarlos con datos demográficos y el nivel de ansiedad de los participantes. Este es un estudio clínico prospectivo con 60 participantes, divididos en 3 grupos de procedimientos dentales: (1) tratamiento restaurador, (2) extracciones y biopsias, y (3) tratamiento gingival. Se recogió un cuestionario de nivel de ansiedad antes del procedimiento odontológico propuesto por la Escala de Ansiedad Dental de Corah. Se midieron la frecuencia respiratoria, la presión sistólica y diastólica, la temperatura y la oxigenación antes, durante y después de los procedimientos. Se incluyeron 31 (51,7 %) mujeres y 29 (48,3 %) hombres, con edad media de 41,75 años. La mayoría de los participantes (50 %) fueron clasificados como muy poco ansiosos. La presión diastólica antes del procedimiento fue mayor en los pacientes ligeramente ansiosos en comparación con los pacientes muy poco ansiosos(p=0,028). La presión sistólica antes, durante y después del procedimiento fue mayor para los participantes mayores de 40 años (p=0,001). La frecuencia cardíaca (p=0,050) y la temperatura (p=0,041) fueron mayores antes del tratamiento restaurativo. La ansiedad puede promover cambios en los signos vitales en el entorno dental. Los signos vitales, el sexo, la edad y el nivel de ansiedad sí influyen en la presión arterial en los diferentes momentos clínicos. Los procedimientos dentales tienen asociación con variaciones de temperatura, frecuencia cardíaca y respiratoria.

RESUMEN

INTRODUÇÃO: A asma brônquica é uma doença crônica inflamatória de alta frequência mundialmente, e em especial no Brasil, onde ocorreram mais de 100.000 internações por ano, segundo dados do DATASUS. Identificar pacientes em admissão hospitalar que poderão necessitar de leito em UTI ou uso de ventilação mecânica por conta de crises asmáticas é um desafio ao profissional de saúde, portanto, faz-se importante analisar variáveis clínicas que possam predispor agravos e avaliar pacientes mais vulneráveis, para que as condutas realizadas sejam efetivas e rápidas. OBJETIVO: Analisar o perfil clínico e epidemiológico de pacientes internados em um hospital do sul do Brasil e avaliar os preditores relacionados ao maior tempo de internação. MÉTODOS: Estudo epidemiológico observacional, do tipo transversal, que utilizou como fonte de informação dados secundários, os quais foram obtidos através de prontuários de pacientes internados em um hospital do sul do Brasil. RESULTADOS: Foram analisados 261 prontuários. Verificou-se que a população menor de 40 anos de idade teve maior prevalência, representando 57% das internações. Além disso, em relação a gênero e etnia, mulheres e caucasianos foram as populações com maiores taxas de hospitalização, sendo 63% e 87% das admissões hospitalares, respectivamente.A necessidade de internação em UTI foi encontrada em 1,1% dos casos (3 pacientes), cerca de 6,9% tiveram internações prolongadas (maiores de 3 dias), e 0,8% vieram à óbito (2 pacientes). Identificou-se que a baixa saturação de oxigênio e a alta frequência cardíaca tiveram relação significativa com internação prolongada. CONCLUSÃO: É importante analisar sinais vitais no momento das admissões hospitalares e o perfil epidemiológico dos pacientes para que as populações mais prevalentes e os fatores preditivos de desfechos mais graves possam ser acompanhados e a conduta a ser tomada seja adequada e efetiva.

INTRODUCTION: Bronchial asthma is a chronic inflammatory disease with a high worldwide frequency, especially in Brazil, where more than 100,000 asthma-related hospitalizations occur annually according to DATASUS data. Identifying patients upon hospital admission who may require an ICU bed or mechanical ventilation due to an asthma attack is a challenge for healthcare professionals. It is important to analyze clinical variables that may predispose to deterioration and evaluate more vulnerable patients to ensure that effective interventions are instituted promptly. OBJECTIVE: To analyze the clinical and epidemiological profile of patients admitted due to asthma in a hospital in southern Brazil and evaluate predictors of longer hospital stay. METHODS: Observational epidemiological study with a cross-sectional design.The source of information were secondary data obtained from medical records of patients admitted to a hospital in southern Brazil. RESULTS: Overall, 261 medical records were analyzed.Patients were predominantly under the age of 40, representing 57% of hospitalizations. In terms of gender and ethnicity, most patients were female (63%) and white (87%).Three patients (1.1%) required ICU admission, approximately 6.9% had prolonged hospitalizations (>3 days), and 2 (0.8%) died. Low oxygen saturation and elevated heart rate correlated significantly with prolonged hospitalization. CONCLUSION: Vital signs at the time of hospital admission and the epidemiological profile of patients should be analyzed, so that the most prevalent populations and predictors of severe outcomes can be monitored, and appropriate and effective measures can be taken.

RESUMEN

A sepse e o choque séptico são as principais preocupações globais de saúde no mundo e um grave problema de saúde no Brasil, sendo uma das principais causas de mortalidade nas unidades de terapia intensiva. O óxido nítrico na fisiopatologia da sepse tem sido usado como um biomarcador de gravidade em pacientes sépticos devido as alterações hemodinâmicas microvascular e sistêmicas, refletindo em alterações dos sinais vitais, causadas pelo excesso de óxido nítrico. O objetivo deste trabalho, foi demonstrar a relevância da verificação dos sinais vitais e análise de exames laboratoriais mais comuns na sepse, correlacionado os mesmos com as concentrações plasmáticas de óxido nítrico, no sentido de monitorar o paciente com sepse e choque séptico. O estudo foi realizado em dois hospitais brasileiros, sendo o hospital A localizado no sul de minas gerais e o hospital B na região noroeste paulista, constituídos de 166 pacientes maiores de 18 anos, sendo 104 pacientes do hospital A e 62 do hospital B, que apresentaram diagnóstico de sepse e choque séptico confirmados e internados nas unidades de clínica médica/cirúrgica, urgência/emergência, maternidade e terapia intensiva. As orientações e aceite em participar do estudo foram realizadas no próprio leito do paciente após sua estabilização clínica e a abordagem aos familiares e/ou responsável legal para aqueles pacientes com instabilidade hemodinâmica. Os dados demográficos, clínicos e laboratoriais foram coletados por meio do prontuário eletrônico, a aferição dos sinais vitais e coleta de sangue após a confirmação do diagnóstico de sepse ou choque séptico, entre março de 2021 a janeiro de 2022. As amostras contendo 3 ml de sangue, identificadas e rotuladas, foram centrifugadas em rotação de 3.500 rpm, por 10 minutos a temperatura de 23ºC a 25ºC. Ao final, o sobrenadante contendo plasma sanguíneo foi desproteinizado por incubação com etanol absoluto 4ºC, mantido por 30 minutos em freezer (-20ºC). Posteriormente submetidas à centrifugação 10.000 rpm por 10 minutos à 23ºC e realizado a técnica de quimiluminescência NO/ozônio. Os resultados evidenciaram maiores concentrações plasmáticas de nitrato em pacientes com piores prognósticos e desfechos, e correlação com sinais vitais e exames laboratoriais da sepse que evidenciam a presença de disfunção orgânica. Quanto maior o nitrato maior foram os níveis de lactato plasmático, ureia, creatinina, potássio e tempo de protrombina, e menores a contagem das plaquetas no sangue. Dentre os sinais vitais, os valores da temperatura corporal, a pressão diastólica e a pressão arterial média foram menores quando evidenciado maiores concentrações de nitrato. Em conjunto, os resultados encontrados mostram que o aumento da concentração do nitrato se associa com a gravidade da sepse e entre as alterações dos sinais vitais, a hipotermia mostrou-se um dado vital de alerta à gravidade clínica dos pacientes. As alterações da frequência respiratória e a pressão sistólica são componentes de escores de gravidade utilizados na prática clínica atual, porém esses sinais vitais não foram evidenciados como sinalizadores de alerta à gravidade de pacientes sépticos.

Sepsis and septic shock are the main global health concerns in the world and a serious health problem in Brazil, being one of the main causes of mortality in intensive care units. Nitric oxide in the pathophysiology of sepsis plays as a biomarker of severity in septic patients due to microvascular and systemic hemodynamic changes, reflecting changes in vital signs caused by excess nitric oxide. The objective of this work was to demonstrate the relevance of checking vital signs and analyzing the most common laboratory tests in sepsis, correlating them with plasma nitric oxide concentrations, in order to monitor patients with sepsis and septic shock. The study was carried out in two Brazilian hospitals - hospital A located in the south of Minas Gerais and hospital B in the northwestern region of São Paulo - consisting of 166 patients over 18 years old, 104 patients from hospital A and 62 from hospital B, which had had a confirmed diagnosis of sepsis and septic shock and were admitted to medical/surgical, urgency/emergency, maternity and intensive care units. The instructions and acceptance to participate in the study were carried out at the patient's own bed after clinical stabilization and the approach to family members and/or legal guardians for those patients with hemodynamic instability. Demographic, clinical and laboratory data were collected through electronic medical records, measurement of vital signs and blood collection after confirmation of the diagnosis of sepsis or septic shock, between March 2021 and January 2022. Samples containing 3 ml of blood, identified and labeled, were centrifuged at 3,500 rpm for 10 minutes at a temperature of 23ºC to 25ºC. Finally, the supernatant containing blood plasma was deproteinized by incubation with absolute ethanol at 4ºC, kept for 30 minutes in a freezer (-20ºC). Subsequently, they were subjected to centrifugation at 10,000 rpm for 10 minutes at 23ºC and the NO/ozone chemiluminescence technique was performed. The results showed higher plasma nitrate concentrations in patients with worse prognoses and outcomes, and correlation with vital signs and sepsis laboratory tests that demonstrate the presence of organic dysfunction. The higher the nitrate, the higher the levels of plasma lactate, urea, creatinine, potassium and prothrombin time, and the lower the blood platelet count. Among vital signs, body temperature, diastolic pressure and mean arterial pressure values were lower when there was higher nitrate concentrations. Altogether, the results found show that the increase in nitrate concentration is associated with the severity of sepsis and among the changes in vital signs, hypothermia proved to be a vital indicator of the clinical severity of patients. Respiratory rate and systolic pressure are components of severity scores used in current clinical practice, but these vital signs have not been demonstrated as warning signs of the severity of septic patients.

RESUMEN

The objective was to evaluate the Modified Early Warning Score in patients hospitalized for COVID-19 plus chronic disease. METHODS: Retrospective observational study, 430 hospitalized patients with COVID-19 and chronic disease. Instrument, Modified Early Warning Score (MEWS). Data analysis, with Cox and logistic regression, to predict survival and risk. RESULTS: Of 430 patients, 58.6% survived, and 41.4% did not. The risk was: low 53.5%, medium 23.7%, and high 22.8%. The MEWS score was similar between survivors 3.02, p 0.373 (95% CI: -0.225-0.597) and non-survivors 3.20 (95% CI: -0.224-0.597). There is a linear relationship between MEWS and mortality risk R 0.920, ANOVA 0.000, constant 4.713, and coefficient 4.406. The Cox Regression p 0.011, with a risk of deterioration of 0.325, with a positive coefficient, the higher the risk, the higher the mortality, while the invasive mechanical ventilation coefficient was negative -0.757. By providing oxygen and ventilation, mortality is lower. CONCLUSIONS: The predictive value of the modified early warning score in patients hospitalized for COVID-19 and chronic disease is not predictive with the MEWS scale. Additional assessment is required to prevent complications, especially when patients are assessed as low-risk.

RESUMEN

OBJECTIVES: To determine the incidence of seizure-like events in a cohort of infants born preterm as well as the prevalence of associated vital sign changes (heart rate [HR], respiratory rate, and pulse oximetry [SpO2]). STUDY DESIGN: We performed prospective conventional video electroencephalogram monitoring on infants born at 23-30 weeks of gestational age during the first 4 postnatal days. For detected seizure-like events, simultaneously captured vital sign data were analyzed during the pre-event baseline and during the event. Significant vital sign changes were defined as HR or respiratory rate >±2 SD from the infant's own baseline physiologic mean, derived from a 10-minute interval before the seizure-like event. Significant change in SpO2 was defined as oxygen desaturation during the event with a mean SpO2 <88%. RESULTS: Our sample included 48 infants with median gestational age of 28 weeks (IQR 26-29) and birth weight of 1125 g (IQR 963-1265). Twelve (25%) infants had seizure-like discharges with a total of 201 events; 83% (10/12) of infants had vital sign changes during these events, and 50% (6/12) had significant vital sign changes during the majority of the seizure-like events. Concurrent HR changes occurred the most frequently. CONCLUSIONS: Individual infant variability was observed in the prevalence of concurrent vital sign changes with electroencephalographic seizure-like events. Physiologic changes associated with preterm electrographic seizure-like events should be investigated further as a potential biomarker to assess the clinical significance of such events in the preterm population.

RESUMEN

ABSTRACT Objective: to analyze the characteristics of the activation of the yellow code in wards and identify the factors associated with adverse events after the Rapid Response Team. Methods: a cross-sectional study with retrospective analysis of medical records of adults admitted to medical or surgical clinic wards of the University Hospital of São Paulo. Results: among the 91 patients, the most frequent signs of triggers (n=107) were peripheral oxygen saturation of less than 90% (40.2%) and hypotension (30.8%). Regarding the associated factors the research identified each minute of attendance of the Rapid Response Team in the wards increased by 1.2% odds of adverse events (twenty-four unplanned admission in the ICU and one cardiac arrest) in the sample (p=0.014). Conclusions: decreased oxygen saturation and hypotension were the main reasons for the triggering, and the length of care was associated with the frequency of adverse events.

RESUMEN

The COVID-19 pandemic further highlighted the need to use low-cost remote monitoring procedures for medical patients. Since the results reported in the literature have shown that the use of Channel State Information (CSI) from Wi-Fi networks to remotely monitor patients can provide means to obtain a powerful medical information package in a non-invasive way and at low cost, a consistent review and analysis of the state of the art on this applied technique is developed in the present work. Initially, a mathematical overview of the CSI technology and its functional model is done. Subsequently, details about the technical approach necessary to use CSI in medical applications and a summary of the studies reported in the literature with such applications are presented. Based on the analyses and discussions carried out throughout this work, a better understanding of the current state of the art is achieved. Challenges and perspectives for future research are also highlighted.

RESUMEN

BACKGROUND: COVID-19 caused more than 622 thousand deaths in Brazil. The infection can be asymptomatic and cause mild symptoms, but it also can evolve into a severe disease and lead to death. It is difficult to predict which patients will develop severe disease. There are, in the literature, machine learning models capable of assisting diagnose and predicting outcomes for several diseases, but usually these models require laboratory tests and/or imaging. METHODS: We conducted a observational cohort study that evaluated vital signs and measurements from patients who were admitted to Hospital das Clínicas (São Paulo, Brazil) between March 2020 and October 2021 due to COVID-19. The data was then represented as univariate and multivariate time series, that were used to train and test machine learning models capable of predicting a patient's outcome. RESULTS: Time series-based machine learning models are capable of predicting a COVID-19 patient's outcome with up to 96% general accuracy and 81% accuracy considering only the first hospitalization day. The models can reach up to 99% sensitivity (discharge prediction) and up to 91% specificity (death prediction). CONCLUSIONS: Results indicate that time series-based machine learning models combined with easily obtainable data can predict COVID-19 outcomes and support clinical decisions. With further research, these models can potentially help doctors diagnose other diseases.

RESUMEN

RESUMO Objetivo: Avaliar a eficácia da solução Welch Allyn Connex® Spot Monitor/Hillrom Connecta™ em acionar o time de resposta rápida em tempo hábil, em comparação com o acionamento manual. Métodos: O estudo Hillrom é um ensaio clínico unicêntrico, aberto, de superioridade, randomizado em clusters em paralelo (taxa de alocação 1:1) realizado em um hospital terciário. Serão incluídos dois grupos de três enfermarias com 28 leitos (um grupo intervenção e um grupo controle). As enfermarias serão distribuídas aleatoriamente para utilizar a solução automatizada Welch Allyn Connex® Spot Monitor/Hillrom Connecta™ (grupo intervenção) ou para manter a rotina habitual (grupo controle) em relação ao acionamento do time de resposta rápida. O desfecho primário será o número absoluto de ocorrências de acionamento do time de resposta rápida em tempo hábil. Como desfechos secundários, características clínicas como mortalidade, parada cardíaca, necessidade de internação em unidade de terapia intensiva e duração da hospitalização serão avaliadas de forma exploratória de acordo com os grupos. Estimou-se uma amostra de 216 acionamentos de time de resposta rápida, para identificar uma possível diferença entre os grupos. O protocolo foi aprovado pelo Comitê de Ética em Pesquisa institucional. Resultados esperados: Espera-se que a solução automatizada Welch Allyn Connex® Spot Monitor/Hillrom Connecta™ seja mais eficaz no acionamento do sistema de chamada de enfermeiros, para acionar o time de resposta rápida em tempo hábil e de maneira adequada, em comparação com o acionamento manual (prática habitual). ClinicalTrials.gov: NCT04648579

ABSTRACT Objective: To evaluate the effectiveness of the Welch Allyn Connex® Spot Monitor/Hillrom Connecta™ solution in activating the rapid response team in a timely manner compared to manual activation. Methods: The Hillrom study is a single-center, open-label, superiority, cluster-randomized, parallel-group (1:1 allocation ratio) clinical trial that will be conducted in a tertiary hospital. Two sets of three wards with 28 beds will be included (one as the intervention cluster and the other as the control). The wards will be randomly assigned to use the Welch Allyn Connex® Spot Monitor/Hillrom Connecta™ automated solution (intervention cluster) or to maintain the usual routine (control cluster) regarding rapid response team activation. The primary outcome will be the absolute number of episodes of rapid response team triggering in an appropriate time; as secondary outcomes, clinical features (mortality, cardiac arrest, need for intensive care unit admission and duration of hospitalization) will be assessed according to clusters in an exploratory way. A sample size of 216 rapid response team activations was estimated to identify a possible difference between the groups. The protocol has been approved by the institutional Research Ethics Committee. Expected results: The Welch Allyn Connex® Spot Monitor/Hillrom Connecta™ automated solution is expected to be more effective in triggering the nurse call system to activate the rapid response team in a timely and adequate manner compared to manual triggering (usual practice).

RESUMEN

OBJECTIVE: To examine the effects of hydrokinesiotherapy in a bucket on physiological parameters and clinical outcomes of hospitalized preterm newborns. METHODS: In this randomized controlled trial, 34 preterm newborns with low birth weight were randomly allocated into experimental (EG) or control (CG) groups and were assessed four times on two alternate days: pre-intervention, post-intervention, 15 min after the intervention, 30 min after post-intervention. On both days, between pre-and post-intervention, the EG underwent hydrokinesiotherapy in a bucket for 10 min and the CG only had the diaper changed. Physiological parameters and body weight gain were considered primary outcomes. Behavioral state and degree of respiratory distress were secondary outcomes. RESULTS: Newborns in the EG presented transitory changes in heart and respiratory rates after the intervention. Oxygen saturation was higher in the EG compared to the CG at post-intervention and up to at least 15 min after post-intervention on both days. The EG was in a more active state than the CG at post-intervention on both days. These changes occurred within normal ranges. Body temperature, degree of respiratory distress, and body weight gain did not differ between groups. CONCLUSION: The hydrokinesiotherapy caused isolated changes in the physiological parameters and led to a more active behavioral state in hospitalized preterm newborns with low birth weight. These changes did not affect the newborns' clinical conditions. The technique was safe, but clinical outcomes, including body weight gain, were not improved.

RESUMEN

OBJECTIVE: To evaluate the predictive capacity of vital signs for the diagnosis of postpartum hemorrhage (PPH). METHODS: A prospective cohort study performed at the University of Campinas, Brazil, between February 2015 and March 2016 with women who delivered vaginally. Vital signs and postpartum bleeding were collected over 24 h. Exploratory data analysis was performed plus receiver operating characteristic curve analysis where the areas under the curve was used to determine the best cutoff points for sensitivity, specificity, likelihood ratio, and diagnostic odds ratio. RESULTS: For the 270 women recruited, mean blood loss after 120 min was 427.49 ± 335.57 ml, while 84 (31.1%) and 22 (8.1%) women had blood loss ≥500 and ≥1000 ml, respectively. Heart rate cutoff point of 105 bpm measured between 21-40 min after birth identified blood loss ≥1000 ml with 90% specificity. A shock index (SI) of 0.965 at 41-60 min after birth identified blood loss ≥500 and ≥1000 ml within 2 h with approximately 95% specificity. CONCLUSION: Shock index and heart rate measured after birth showed high specificity with low sensitivity to identify PPH. In clinical practice, "The rule of 1s" should receive special attention: SI ≥1, or heart rate >100 bpm, or estimated blood loss ≥1 L.

RESUMEN

Avaliar a associação da medida de frequência cardíaca (FC) e saturação periférica de oxigênio (SpO2 ) utilizando um aplicativo de celular e um monitor multiparamétrico. Métodos: Estudo experimental e randomizado entre participantes saudáveis. Investigou o aplicativo Samsung Health® e o monitor multiparamétrico da marca Midway®, modelo: PM-60. O estudo foi estruturado em quatro etapas. Para análise estatística, aplicou correlação de Pearson e Spearman, com nível de significância de 5%. Resultados: Dos 150 participantes a idade média foi de 22,3±4,5 anos, o sexo feminino foi predominante (71,3%). Verificouse forte correlação da FC medida pelo monitor com a FC do aplicativo de celular (r=0,93) indicando correlação positiva (p<0,001). A SpO2 medida por monitor multiparamétrico e pelo aplicativo de celular revelou um r=0,05 (p=0,51), o que atesta uma correlação nula e não significativa. Conclusão: Não houve correlação entre a medida da SpO2 do monitor multiparamétrico e do aplicativo Samsung Health®, não sendo confiável a utilização deste aplicativo para monitorar e gerenciar o sinal vital SpO2 em pessoas saudáveis. A FC medida com o aplicativo é significativa, e pode ser utilizada para monitorar e gerenciar esse sinal vital.
