Acute kidney injury: the experience of a tertiary center of Pediatric Nephrology / Insuficiência renal aguda: experiência de um centro terciário de Nefrologia Pediátrica

ABSTRACT Introduction: Acute kidney injury (AKI) is an abrupt deterioration of kidney function. The incidence of pediatric AKI is increasing worldwide, both in critically and non-critically ill settings. We aimed to characterize the presentation, etiology, evolution, and outcome of AKI in pediatric patients admitted to a tertiary care center. Methods: We performed a retrospective observational single-center study of patients aged 29 days to 17 years and 365 days admitted to our Pediatric Nephrology Unit from January 2012 to December 2021, with the diagnosis of AKI. AKI severity was categorized according to Kidney Disease Improving Global Outcomes (KDIGO) criteria. The outcomes considered were death or sequelae (proteinuria, hypertension, or changes in renal function at 3 to 6 months follow-up assessments). Results: Forty-six patients with a median age of 13.0 (3.5-15.5) years were included. About half of the patients (n = 24, 52.2%) had an identifiable risk factor for the development of AKI. Thirteen patients (28.3%) were anuric, and all of those were categorized as AKI KDIGO stage 3 (p < 0.001). Almost one quarter (n = 10, 21.7%) of patients required renal replacement therapy. Approximately 60% of patients (n = 26) had at least one sequelae, with proteinuria being the most common (n = 15, 38.5%; median (P25-75) urinary protein-to-creatinine ratio 0.30 (0.27-0.44) mg/mg), followed by reduced glomerular filtration rate (GFR) (n = 11, 27.5%; median (P25-75) GFR 75 (62-83) mL/min/1.73 m2). Conclusions: Pediatric AKI is associated with substantial morbidity, with potential for proteinuria development and renal function impairment and a relevant impact on long-term prognosis.

RESUMO Introdução: Insuficiência renal aguda (IRA) é uma deterioração abrupta da função renal. A incidência de IRA pediátrica está aumentando em todo o mundo, em ambientes críticos e não críticos. Nosso objetivo foi caracterizar apresentação, etiologia, evolução e desfechos da IRA em pacientes pediátricos internados em um centro de atendimento terciário. Métodos: Realizamos estudo retrospectivo observacional de centro único de pacientes com idade entre 29 dias a 17 anos e 365 dias internados em nossa Unidade de Nefrologia Pediátrica, de janeiro de 2012 a dezembro de 2021, com diagnóstico de IRA. A gravidade da IRA foi categorizada de acordo com os critérios do Kidney Disease Improving Global Outcomes (KDIGO). Os desfechos considerados foram óbito ou sequelas (proteinúria, hipertensão ou alterações na função renal em avaliações de acompanhamento de 3 a 6 meses). Resultados: Incluímos 46 pacientes com idade mediana de 13,0 (3,5-15,5) anos. Cerca de metade (n = 24; 52,2%) apresentou um fator de risco identificável para o desenvolvimento de IRA. Treze pacientes (28,3%) eram anúricos; todos foram classificados como IRA KDIGO 3 (p < 0,001). Quase um quarto (n = 10; 21,7%) dos pacientes necessitaram de terapia renal substitutiva. Aproximadamente 60% (n = 26) apresentou pelo menos uma sequela, sendo proteinúria a mais comum (n = 15; 38,5%; mediana (P25-75) da relação proteína/creatinina urinária 0,30 (0,27-0,44) mg/mg), seguida de taxa de filtração glomerular (TFG) reduzida (n = 11; 27,5%; mediana (P25-75) da TFG 75 (62-83) mL/min/1,73 m2). Conclusões: A IRA pediátrica está associada à morbidade substancial, com potencial para desenvolvimento de proteinúria e comprometimento da função renal e impacto relevante no prognóstico de longo prazo.

Estimated glomerular filtration rate in clinical practice: Consensus positioning of the Brazilian Society of Nephrology (SBN) and Brazilian Society of Clinical Pathology and Laboratory Medicine (SBPC/ML) / Estimativa da taxa de filtração glomerular na prática clínica: posicionamento consensual da Sociedade Brasileira de Nefrologia (SBN) e Sociedade Brasileira de Patologia Clínica e Medicina Laboratorial (SBPC/ML)

ABSTRACT Chronic kidney disease (CKD) represents one of today's main public health problems. Serum creatinine measurement and estimation of the glomerular filtration rate (GFR) are the main tools for evaluating renal function. There are several equations to estimate GFR, and CKD-EPI equation (Chronic Kidney Disease - Epidemiology) is the most recommended one. There are still some controversies regarding serum creatinine measurement and GFR estimation, since several factors can interfere in this process. An important recent change was the removal of the correction for race from the equations for estimating GFR, which overestimated kidney function, and consequently delayed the implementation of treatments such as dialysis and kidney transplantation. In this consensus document from the Brazilian Societies of Nephrology and Clinical Pathology and Laboratory Medicine, the main concepts related to the assessment of renal function are reviewed, as well as possible existing controversies and recommendations for estimating GFR in clinical practice.

RESUMO A doença renal crônica (DRC) representa um dos principais problemas de saúde pública da atualidade. A dosagem da creatinina sérica e a estimativa da taxa de filtração glomerular (TFG) são as principais ferramentas para avaliação da função renal. Para a estimativa da TFG, existem diversas equações, sendo a mais recomendada a CKD-EPI (Chronic Kidney Disease - Epidemiology). Existem ainda algumas controvérsias com relação à dosagem da creatinina sérica e da estimativa da TFG, uma vez que vários fatores podem interferir nesse processo. Uma importante mudança recente foi a retirada da correção por raça das equações para estimativa da TFG, que superestimavam a função renal, e consequentemente retardavam a implementação de tratamentos como diálise e transplante renal. Neste documento de consenso da Sociedade Brasileira de Nefrologia e Sociedade Brasileira de Patologia Clínica e Medicina Laboratorial são revisados os principais conceitos relacionados à avaliação da função renal, possíveis controvérsias existentes e recomendações para a estimativa da TFG na prática clínica.

Risk factors for acute kidney injury in patients hospitalized with COVID-19 / Fatores de risco para lesão renal aguda em pacientes hospitalizados com COVID-19

Abstract Introduction: Acute kidney injury (AKI) occurs frequently in COVID-19 patients and is associated with greater morbidity and mortality. Knowing the risks of AKI allows for identification, prevention, and timely treatment. This study aimed to identify the risk factors associated with AKI in hospitalized patients. Methods: A descriptive, retrospective, cross-sectional, and analytical component study of adult patients hospitalized with COVID-19 from March 1 to December 31, 2020 was carried out. AKI was defined by the creatinine criteria of the KDIGO-AKI guidelines. Information, regarding risk factors, was obtained from electronic medical records. Results: Out of the 934 patients, 42.93% developed AKI, 60.59% KDIGO-1, and 9.9% required renal replacement therapy. Patients with AKI had longer hospital stay, higher mortality, and required more intensive care unit (ICU) admission, mechanical ventilation, and vasopressor support. Multivariate analysis showed that age (OR 1.03; 95% CI 1.02-1.04), male sex (OR 2.13; 95% CI 1.49-3.04), diabetes mellitus (DM) (OR 1.55; 95% CI 1.04-2.32), chronic kidney disease (CKD) (OR 2.07; 95% CI 1.06-4.04), C-reactive protein (CRP) (OR 1.02; 95% CI 1.00-1.03), ICU admission (OR 1.81; 95% CI 1.04-3.16), and vasopressor support (OR 7.46; 95% CI 3.34-16.64) were risk factors for AKI, and that bicarbonate (OR 0.89; 95% CI 0.84-0.94) and partial pressure arterial oxygen/inspired oxygen fraction index (OR 0.99; 95% CI 0.98-0.99) could be protective factors. Conclusions: A high frequency of AKI was documented in COVID-19 patients, with several predictors: age, male sex, DM, CKD, CRP, ICU admission, and vasopressor support. AKI occurred more frequently in patients with higher disease severity and was associated with higher mortality and worse outcomes.

RESUMO Introdução: Lesão renal aguda (LRA) ocorre frequentemente em pacientes com COVID-19 e associa-se a maior morbidade e mortalidade. Conhecer riscos da LRA permite a identificação, prevenção e tratamento oportuno. Este estudo teve como objetivo identificar fatores de risco associados à LRA em pacientes hospitalizados. Métodos: Realizou-se estudo descritivo, retrospectivo, transversal e de componente analítico de pacientes adultos hospitalizados com COVID-19 de 1º de março a 31 de dezembro, 2020. Definiu-se a LRA pelos critérios de creatinina das diretrizes KDIGO-LRA. Informações sobre fatores de risco foram obtidas de prontuários eletrônicos. Resultados: Dos 934 pacientes, 42,93% desenvolveram LRA, 60,59% KDIGO-1 e 9,9% necessitaram de terapia renal substitutiva. Pacientes com LRA apresentaram maior tempo de internação, maior mortalidade e necessitaram de mais internações em UTIs, ventilação mecânica e suporte vasopressor. A análise multivariada mostrou que idade (OR 1,03; IC 95% 1,02-1,04), sexo masculino (OR 2,13; IC 95% 1,49-3,04), diabetes mellitus (DM) (OR 1,55; IC 95% 1,04-2,32), doença renal crônica (DRC) (OR 2,07; IC 95% 1,06-4,04), proteína C reativa (PCR) (OR 1,02; IC 95% 1,00-1,03), admissão em UTI (OR 1,81; IC 95% 1,04-3,16) e suporte vasopressor (OR 7,46; IC 95% 3,34-16,64) foram fatores de risco para LRA, e que bicarbonato (OR 0,89; IC 95% 0,84-0,94) e índice de pressão parcial de oxigênio arterial/fração inspirada de oxigênio (OR 0,99; IC 95% 0,98-0,99) poderiam ser fatores de proteção. Conclusões: Documentou-se alta frequência de LRA em pacientes com COVID-19, com diversos preditores: idade, sexo masculino, DM, DRC, PCR, admissão em UTI e suporte vasopressor. LRA ocorreu mais frequentemente em pacientes com maior gravidade da doença e associou-se a maior mortalidade e piores desfechos.

Fasting glucose: a cardiometabolic indicator for subclinical atherosclerosis on excess weight adolescents

Abstract Objective: To build a model based on cardiometabolic indicators that allow the identification of overweight adolescents at higher risk of subclinical atherosclerotic disease (SAD). Methods: Cross-sectional study involving 161 adolescents with a body mass index ≥ + 1 z-Score, aged 10 to 19 years. Carotid intima-media complex thickness (IMT) was evaluated using ultrasound to assess subclinical atherosclerotic disease. Cardiometabolic indicators evaluated included nutritional status, central adiposity, blood pressure, lipidic profile, glycemic profile, as well as age and sex. Data was presented using measures of central tendency and dispersion, as well as absolute and relative frequency. The relationship between IMT measurement (outcome variable) and other variables (independent variables) was assessed using Pearson or Spearman correlation, followed by multiple regression modeling with Gamma distribution to analyze predictors of IMT. Statistical analysis was performed using SPSS and R software, considering a significance level of 5 %. Results: It was observed that 23.7 % had Carotid thickening, and the prevalence of abnormal fasting glucose was the lowest. Age and fasting glucose were identified as predictors of IMT increase, with IMT decreasing with age by approximately 1 % per year and increasing with glucose by around 0.24 % per mg/dL. Conclusion: The adolescent at higher risk is younger with higher fasting glycemia levels.

The newborn screening tests in Brazil: regional and socioeconomic prevalence and inequalities in 2013 and 2019

Abstract Objective: To analyze the prevalence evolution of Guthrie, hearing, and eye screening testing among newborns in Brazil, between 2013 and 2019, according to demographic and socioeconomic characteristics. Methods: This is a cross-sectional study with data from 5231 infants from the Pesquisa Nacional de Saude (PNS), in 2013, and 6637 infants, in 2019, for the Guthrie test, hearing, and red reflex tests. The authors analyzed the outcomes according to the region of residence, self-reported color/race, having health insurance, and per capita household income. By using bivariate and multivariate Poisson regression models, the prevalence ratios and their respective 95 % Confidence Intervals (CI95%) were calculated for each year. Results: In 2013, Guthrie test, hearing, and red reflex tests were performed in 96.5 % (95%CI 95,8;97,0), 65.8 % (95%CI 63,9;67,7), and 60.4 % (95%CI 58,5;62,3) of infants, respectively. In 2019, the prevalence was 97.8 % (95%CI 97,3;98,2) in the Guthrie test, 81.6 % (95%CI 80,3;82,9) in the hearing test, and 78.6 % (95%CI 77,1;79,9) in the red reflex test. The testing frequency was higher among residents of the Southeast and South regions of Brazil, among infants whose mother or guardian was white, had health insurance, and was in the higher income strata; and the most evident differences were in the eye and hearing testing. Conclusions: The coverage inequalities according to the region of residence, income, and having health insurance highlight the need to use strategies that enable exams to be carried out, with more information about their importance, encompassing actions from primary care, prenatal care to the puerperium, aiming at universal access and equity.

Behind the Headset: Predictive Accuracy of Patient-Reported Outcome Measures for Voice Symptoms in Call Centers

Objective: This study examines factors predicting self-reported voice symptoms in call center workers. Methods: Multivariate analysis and predictive modeling assess personal, work-related, acoustic, and behavioral factors. Generalized Linear Models (GLMs) and Receiver Operating Characteristic (ROC) curves are employed. Results: Age and sleep patterns impacted voice quality and effort, while workplace factors influenced symptom perception. Unhealthy vocal behaviors related to tense voice and increased effort, while hydration was protective. Voice acoustics showed diagnostic potential, supported by ROC data. These findings emphasize voice symptom complexity in call center professionals, necessitating comprehensive assessment. Limitations: This study recognizes its limitations, including a moderate-sized convenience sample and reliance on PROM metrics. Future research should incorporate more objective measures in addition to self-reports and acoustic analysis. Value: This research provides novel insights into the interplay of personal, occupational, and voice-related factors in developing voice symptoms among call center workers. Predictive modeling enhances risk assessment and understanding of individual susceptibility to voice disorders. Conclusion: Results show associations between various factors and self-reported voice symptoms. Protective factors include sleeping more than six hours and consistent hydration, whereas risk factors include working conditions, such as location and behaviors like smoking. Diagnostic models indicate good accuracy for some voice symptom PROMs, emphasizing the need for comprehensive models considering work factors, vocal behaviors, and acoustic parameters to understand voice issues complexity.

Objetivo: Este estudio examina los factores que predicen los síntomas de voz en los trabajadores de call centers. Métodos: Se utilizan análisis multivariados y modelos predictivos para evaluar factores personales, laborales, acústicos y de comportamiento. Se emplean Modelos Lineales Generalizados (GLM) y curvas ROC. Resultados: La edad y los patrones de sueño afectaron la calidad vocal y el esfuerzo, mientras que los factores laborales influyeron en la percepción de síntomas. Los comportamientos vocales no saludables se relacionaron con voz tensa y mayor esfuerzo, mientras que la hidratación fue protectora. Los parámetros acústicos de voz mostraron potencial diagnóstico respaldado por datos de ROC. Los hallazgos subrayan complejidad de síntomas vocales en profesionales de centros de llamadas, requiriendo una evaluación integral. Limitaciones: Este estudio reconoce sus limitaciones, que incluyen una muestra de conveniencia de tamaño moderado y la dependencia de medidas PROMs. Futuras investigaciones deberían incorporar medidas objetivas, además de los autorreportes y análisis acústico. Importancia: Esta investigación aporta nuevos conocimientos sobre factores personales, laborales y síntomas de voz en trabajadores de call centers. El modelado predictivo mejora la evaluación de riesgos y la comprensión de la susceptibilidad individual a trastornos de la voz. Conclusión: Los resultados muestran asociaciones entre diversos factores y los síntomas vocales reportados. Los factores de protección incluyen dormir más de seis horas y una hidratación constante; los factores de riesgo incluyen las condiciones de trabajo, como la ubicación y comportamientos como fumar. Los modelos de diagnóstico indican una buena precisión para algunas PROMs de síntomas de la voz, lo que subraya la necesidad de modelos integrales que tengan en cuenta los factores laborales, los comportamientos vocales y los parámetros acústicos para comprender la complejidad de los problemas de la voz.

Falta de adherencia al control médico en pacientes pediátricos con antecedente de glomerulonefritis infecciosa

Introducción: La glomerulonefritis pos infecciosa (GNPI) en la infancia es un factor de riesgo para el desarrollo de enfermedad renal crónica a largo plazo. La adherencia al control médico permite realizar la nefroprevención secundaria. Objetivo: evaluar la relación entre los factores de riesgo relacionados a la falta de adherencia al control médico de pacientes con GNPI en una cohorte pediátrica. Metodología: estudio descriptivo de asociación cruzada de cohorte retrospectiva de pacientes internados entre enero de 2000 a diciembre de 2018 en un hospital de referencia. Se analizó la relación entre: hacinamiento, colecho, escolaridad materna y paterna, número de hermanos, de convivientes y procedencia, con la falta de adherencia al control médico. Se utilizaron la prueba de chi cuadrado y regresión logística a un nivel de significancia de 0,05. Resultados: Se incluyeron 148 pacientes (103 niños y 45 niñas) entre 2 a 16 años (edad promedio: 8,5± 3,4 años). La falta de adherencia fue encontrada en 73 pacientes (49,3%) que se asoció a procedencia rural (p= 0,012, RR: 1,50, IC95%: 1,10-2,06), baja escolaridad materna (p= 0,046, IC95%: 1,54:1,14-2,08), baja escolaridad paterna (p= 0,02; RR: 1,483, IC95%: 1,09-2,01), >3 convivientes (p=0,007, RR: 1,630, IC95%: 1,21-2,19), colecho (p=0,026; RR: 1,52, IC95%: 1,02-2,27) y hacinamiento (p<0,0001; RR: 1,92, IC95%: 1,39-2,65). Por regresión logística, el hacinamiento (p=0,005; OR= 4,8) y procedencia rural (p=0,022; OR: 2,4) se mantuvieron asociados a la falta de adherencia. Discusión: El hacinamiento y la procedencia rural se asociaron en forma independiente con la pérdida de seguimiento. Se recomienda mayor intervención de la atención primaria de salud.

Introduction: Post-infectious glomerulonephritis (PIGN) in childhood is a risk factor for the development of long-term chronic kidney disease. Adherence to medical control allows secondary nephroprevention to be carried out. Objective: to evaluate the relationship between risk factors related to non-adherence to medical control of patients with IPGN in a pediatric cohort. Methods: descriptive study, with an analytical component of a retrospective cohort of patients hospitalized between January 2000 and December 2018 in a reference hospital. The relationship between: overcrowding, co-sleeping, maternal and paternal education, number of siblings, cohabitants and origin, with lack of adherence to medical control was analyzed. The chi-square test and logistic regression were used at a significance level of 0.05. Results: a total of 148 patients (103 boys y 45 girls) between 2 and 16 years old (mean age: 8.5± 3.4 years) were included. The lack of adherence was found in 73 patients (49.3%) that was associated with rural origin (p= 0.012, RR: 1.50, 95% CI: 1.10-2.06), low maternal education (p= 0.046, 95%CI: 1.54:1.14-2.08), low paternal education (p= 0.02; RR: 1.483, 95%CI: 1.09-2.01), >3 cohabitants (p=0.007, RR: 1.630, 95% CI: 1.21-2.19), co-sleeping (p=0.026; RR: 1.52, 95% CI: 1.02-2.27) and overcrowding (p<0.0001; RR: 1.92, 95% CI: 1.39-2.65). By logistic regression, overcrowding (p=0.005; OR= 4.8) and rural origin (p=0.022; OR: 2.4) remained associated with lack of adherence. Discussion: Overcrowding and rural origin were independently associated with loss to follow-up. Greater intervention by primary health care is recommended.

Obesidad como factor implicado en la gravedad de la infección por SARS-CoV-2

Las personas obesas enfrentan mayores complicaciones al contraer SARS-CoV-2 debido a su estado proinflamatorio crónico y respuesta inmune reducida, relacionados con el exceso de tejido adiposo. La interacción del virus con los receptores ACE2 y la retención de lípidos ectópicos renales son aspectos clave en este contexto. Objetivo. Analizar las características específicas de la obesidad que aumentan la susceptibilidad a síntomas graves de COVID-19, a partir de artículos publicados entre 2020 y 2022, y promover futuras investigaciones. Metodología. Se realizó una revisión sistemática de artículos originales entre 2020 y 2022 utilizando términos clave y operadores booleanos en bases de datos como PubMed, Scopus, ProQuest, etc. Se excluyeron estudios no originales para obtener investigaciones más específicas. Resultados. De 180 artículos encontrados, 42 fueron seleccionados. Entre estos, se destacó que pacientes obesos, especialmente hombres de edad avanzada, presentaron severas complicaciones. Sin embargo, jóvenes con obesidad severa y personas con bajo peso también mostraron mayor riesgo de mortalidad. La disminución de la función pulmonar, bajos niveles de vitamina D, y la alteración de ACE2 fueron implicados en la gravedad de la infección. La hiperglucemia asociada a la obesidad aumentó el riesgo de ingreso a UCI y ventilación mecánica, mientras que la resistencia a la insulina empeoró el pronóstico. Conclusión. La obesidad emerge como un factor de riesgo importante para la gravedad y mortalidad por COVID-19, señalando la necesidad de una atención específica para este grupo de pacientes y la continuación de investigaciones en el área.

Características de la población femenina carcelaria: un caso de la región Caribe de Colombia / Characteristics of the female prison population: a case from the Caribbean region of Colombia / Características da população carcerária feminina: um caso da região caribenha da Colômbia

El objetivo del presente trabajo fue describir las características de las mujeres privadas de libertad (MPL) de un centro de detención carcelario de la región Caribe de Colombia, a partir de un método cuantitativo, descriptivo, transversal, mediante el uso de unidades de análisis documental de una muestra de 202 archivos psicojurídicos de mujeres privadas de libertad, durante los años 2021 y 2022. En estos archivos se encuentran 25 variables divididas en tres grupos. Primer grupo: características sociodemográficas de la población; segundo grupo: datos históricos, relativos a antecedentes familiares y de salud mental; tercer grupo: aspectos relacionados con la conducta delictiva. De acuerdo con los resultados encontrados, la mayor parte de la población son madres, con escaso acceso a oportunidades laborales, bajo nivel de escolaridad, con precarios ingresos económicos, antecedentes de victimización psicológica, sexual o física, exposición a violencia indirecta, antecedentes de abandono y, en algunos casos, se identificó la presencia de diagnósticos en salud mental, consumo de sustancias, comorbilidad y experiencias traumáticas durante su infancia y adolescencia y la prisionalización de padres o familiares. Estos resultados permiten reconocer la importancia de los aspectos históricos y los antecedentes de la conducta delictiva femenina, lo cual resulta fundamental en la prevención de la criminalidad, haciendo frente a los factores de riesgo previos a la conducta delictiva femenina; igualmente, la relevancia del fortalecimiento de un modelo carcelario de cara a las características y necesidades de la población femenina, una política criminal y un sistema penitenciario de género sensitivo, así como la incorporación de los resultados encontrados en el tratamiento carcelario, en la resocialización y en la prevención del fenómeno criminal.

The aim of this study was to describe the characteristics of women deprived of liberty (MPL) in a prison detention centre in the Caribbean region of Colombia, based on a quantitative, descriptive, cross-sectional method, using units of documentary analysis of a sample of 202 psycho-legal files of women deprived of liberty, during the years 2021 and 2022. These files contain 25 variables divided into three groups. First group: socio-demographic characteristics of the population; second group: historical data, relating to family history and mental health; third group: aspects related to criminal behaviour. According to the results found, most of the population are mothers, with little access to job opportunities, low level of schooling, precarious economic income, history of psychological, sexual or physical victimisation, exposure to indirect violence, history of abandonment and, in some cases, the presence of mental health diagnoses, substance use, comorbidity and traumatic experiences during childhood and adolescence and the imprisonment of parents or relatives were identified. These results allow us to recognise the importance of the historical aspects and background of female criminal behaviour, which is fundamental in the prevention of criminality, addressing the risk factors prior to female criminal behaviour; also, the relevance of strengthening a prison model that takes into account the characteristics and needs of the female population, a criminal policy and a gender-sensitive penitentiary system, as well as the incorporation of the results found in prison treatment, in re-socialisation and in the prevention of the criminal phenomenon

Esses resultados permitem reconhecer a importância dos aspectos históricos e dos antecedentes do comportamento criminoso feminino, o que é fundamental na prevenção da criminalidade, abordando os fatores de risco anteriores ao comportamento criminoso feminino; também, a relevância do fortalecimento de um modelo prisional diante das características e necessidades da população feminina, de uma política criminal e de um sistema prisional sensível ao gênero, bem como a incorporação dos resultados encontrados no tratamento prisional, na ressocialização e na prevenção do fenômeno criminal.

Invisibility and devaluation of nursing work: related factors and coping strategies

Nursing represents the largest professional category in the health field worldwide, with 27.9 million professionals, representing 59% of the entire health workforce.(1) The World Health Organization has warned of the need for greater investments in training, better working conditions and encouraging the development of nursing leadership as one of the means to achieve universal health coverage and the Sustainable Development Goals (SDGs).(1) However, even though they are essential to health systems, these professionals face problems related to the representation of their image, which contributes to a scenario of devaluation, which has proved to be an obstacle to the development of the profession. Thus, in an exercise of understanding this phenomenon, it is considered that the factors that follow contribute greatly to configure the devaluation scenario

Replacing screen time, with physical activity and sleep time: influence on cardiovascular indicators and inflammatory markers in Brazilian children

Abstract Objective: To examine if the substitution of different screen time intervals with light physical activity (LPA), moderate to vigorous physical activity (MVPA) and sleep is associated with cardiovascular indicators and inflammatory markers in children. Methods: This is a cross-sectional study developed with 186 children aged between six and 11 years old from public schools in southern Brazil. CRF was measured with the 6-minute running and walking test, following the Brazil Sports Project procedures. The percentage of fat was evaluated through DXA. LPA and MVPA were measured using accelerometers. Sleep and screen time were assessed by questionnaires answered by parents. Leptin and C-reactive protein were measured by fasting blood collection. Systolic and diastolic blood pressure were determined through a digital sphygmomanometer. Isotemporal substitution models were used for statistical analysis. Results: Replacing 1 h of screen time with MVPA was associated with lower BMI, systolic and diastolic blood pressure, fat percentage, leptin, and C-reactive protein. When screen time was substituted for sleep time, lower waist circumference was observed. Regarding the substitution of 1 h of screen time with LPA, significant values were found only for leptin. Conclusion: The replacement of screen time with physical activities of different intensities and sleep time was associated with benefits in cardiovascular indicators and inflammatory markers in childhood.

INTRODUÇÃO: A dor lombar possui alta prevalência, sendo uma das principais causas de incapacidade no Brasil e no mundo. A dor lombar apresenta etiologia multifatorial, sendo extremamente comum em trabalhadores. OBJETIVOS: Verificar o conhecimento sobre os fatores de risco para dor lombar, crenças e atitudes sobre o manejo da dor lombar entre profissionais de saúde (fisioterapeutas e ergonomistas) atuantes na área ocupacional. MATERIAIS E MÉTODOS: Foi realizado um estudo observacional transversal com 81 profissionais de saúde ocupacional brasileiros. Os participantes preencheram um questionário eletrônico composto por dados profissionais, sociodemográficos, itens sobre fatores de risco para dor lombar e a Brazilian version of the Pain Attitudes and Beliefs Scale for Physiotherapists. Conhecimentos, crenças e atitudes foram analisados por meio do teste do qui-quadrado para fatores de risco para dor lombar e um modelo de regressão linear para crenças e atitudes dos profissionais de saúde. RESULTADOS: Obesidade (7,4%), ficar sentado mais de 2 horas (8,6%), atividade física (9,9%), falta de apoio psicossocial no trabalho (11,1%) e consumo de álcool (37,0%), apresentaram os menores índices de conhecimento sobre fatores de risco da dor lombar pelos profissionais. Itens sobre saúde geral apresentaram o menor conhecimento. Uma orientação biomédica e psicossocial equilibrada de crenças e atitudes sobre o manejo da dor lombar foi observada. CONCLUSÃO: Profissionais de saúde ocupacional brasileiros carecem de conhecimento sobre os fatores de risco não ocupacionais da dor lombar, especialmente o estado geral de saúde. Esses profissionais também possuem conceitos biomédicos e psicossociais equilibrados no manejo da dor lombar.

INTRODUCTION: Low back pain (LBP) is highly prevalent and is one of the main causes of disability in Brazil and around the world. LBP presents a multifactorial etiology, being extremely common in workers. OBJECTIVE: This study aimed to verify the knowledge about the LBP risk factors, beliefs and attitudes about the management of LBP among health professionals (physiotherapists and ergonomists) working in the occupational area. MATERIALS AND METHODS: A cross-sectional observational study was conducted with 81 Brazilian occupational health professionals. Participants completed an electronic questionnaire comprising professional data, sociodemographics, items about LBP risk factors, and the Brazilian version of the Pain Attitudes and Beliefs Scale for Physiotherapists. Knowledge, beliefs and attitudes were analyzed using the chi-square test for LBP risk factors and the linear regression model for health professionals' beliefs and attitudes. RESULTS: Obesity (7.4%), sitting for more than 2 hours (8.6%), physical activity (9.9%), lack of psychosocial support at work (11.1%) and consuming alcohol (37.0%) presented the lowest rate of knowledge about LBP risk factors by professionals. Items about general health showed the lowest knowledge. A balanced biomedical and psychosocial orientation of beliefs and attitudes about managing LBP was observed. CONCLUSION: Brazilian occupational health professionals lack knowledge about non-occupational LBP risk factors, especially general health status. These professionals also have balanced biomedical and psychosocial concepts in managing LBP.

Las poblaciones de mayor riesgo son: hombres, adolescentes y jóvenes; residentes de distritos: de selva, del quintil de mayor pobreza monetaria, del quintil con mayor porcentaje con al menos 1 NBI, y del quintil de menor índice de desarrollo humano. Conclusión. La leishmaniasis tiene amplia distribución en Perú, 56,41% de la población habita en distritos que reportan casos. Existen grupos poblacionales con mayor riesgo absoluto, los cuales pueden ser blanco de intervenciones diferenciadas de prevención y control.

ABSTRACT Introduction. Leishmaniasis is an endemic zoonotic disease widely distributed in Peru. Objectives. Identify transmission scenarios and the population residing in them and identify the characteristics of the affected populations during the period 2010-2022. Methods. Descriptive, cross-sectional, ecological study with district as analysis units. Publicly accessible secondary data sources were used. Results. During the study period, 85,117 cases were reported; 7,374,007 (22.08%) inhabitants live in 543 districts with continuous transmission; 1,146,7420 (34.33%) inhabitants reside in 454 districts with sporadic reports of cases; and 1,455,8983 (43.59%) reside in 893 transmission-free districts. 98.16% of the cases occurred in districts with continuous transmission; 1.84% occurred in districts with sporadic case reports. The mean annual incidence rate was 3.48 cases/10,000 inhabitants. 18 departments report continuous transmission; Madre de Dios (42.45 cases/10,000 inhabitants) and Cusco (15.78 cases/10,000 inhabitants) report the highest rates. The populations with higher absolute risk are men, adolescents, and young people; residents: from jungle districts; from the quintile with the highest monetary poverty; from the quintile with the highest percentage with at least 1 NBI; and from the quintile with the lowest human development index. Conclusion. Leishmaniasis is widely distributed in Peru, with 56.41% of the population living in districts reporting cases. There are population groups with a higher absolute risk, which can be the target of differentiated prevention and control interventions.
