Dificultades alimentarias en la infancia: una revisión narrativa / Feeding difficulties in childhood: A narrative review

Se estima que entre el 25 % y el 40 % de los niños sanos presentan algún síntoma de dificultad alimentaria (DA) durante su crecimiento y desarrollo, y muchas veces no son adecuadamente diagnosticadas. El propósito de este trabajo consistió en realizar una revisión narrativa que reuniera la información disponible sobre las dificultades alimentarias. Se desarrollaron algoritmos de evaluación y abordaje a partir de la evidencia en la literatura. La mayoría de los problemas de alimentación en los niños pequeños (selectividad alimentaria, falta de apetito, miedo a la alimentación) a menudo coexisten y es necesario evaluar el riesgo clínico para planificar una intervención individualizada. Contar con definiciones estandarizadas y terminología común para abordar estas dificultades de manera adecuada y multidisciplinaria es uno de los caminos para optimizar su tratamiento. Involucrar a los diferentes profesionales de la salud y a los padres es fundamental para abordar las dificultades alimentarias.

It has been estimated that between 25% and 40% of healthy children show symptoms of feeding difficulties (FDs) during their growth and development; many times, these are not adequately diagnosed. The objective of this study was to conduct a narrative review that collected the available information on fee ding difficulties. Assessment and management algorithms were developed based on the bibliographic evidence. Most feeding problems in young children (feeding selectivity, loss of appetite, fear of feeding) are often con current, and a clinical risk assessment is necessary to plan an individualized intervention. Having standardized definitions and common terms to address these difficulties in an appropriate and multidisciplinary manner is one of the ways to optimize their treatment. The involvement of different health care providers and parents is critical to address feeding difficulties.

Siniestralidad y apnea obstructiva del sueño. Revisión de la literatura y evaluación de la situación en 3 países latinoamericanos / Accident Rate and Obstructive Sleep Apnea: Literature Review and Assessment of the Situation in Three Latin American Countries

La apnea obstructiva del sueño (AOS) es una condición común en adultos en edad laboral. Incluso, en la actualidad, vemos cómo la edad de retiro se ha ido prolongando de tal manera que adultos mayores, quienes tienen mayor prevalencia de AOS, continúan trabajando incluso en situaciones de alto riesgo de siniestralidad. Uno de los principales síntomas de la AOS es la somnolencia diurna que puede contri- buir de manera directa al riesgo de accidentabilidad, compromiso cognitivo y desem- peño laboral. También se ha demostrado cómo la reducción de la materia gris a nivel cerebral y cerebelar provoca alteraciones en coordinación y capacidad de conducción. El tratamiento con dispositivos de presión positiva mejora el desempeño laboral y redu- ce la incidencia de accidentes de tránsito, pero algunos déficits cognitivos pueden per- sistir incluso después de meses de tratamiento. La evaluación del riesgo de accidentabilidad en conductores es un desafío y los cues- tionarios actuales no son adecuados para el cribado. Los simuladores de conducción y las pruebas de alerta son más prometedores. El futuro de la investigación se centra en estandarizar los resultados de los simulado- res, determinar los mejores predictores de eventos reales y utilizar la inteligencia arti- ficial y los automóviles autónomos para reducir los riesgos relacionados con la somno - lencia al volante. Es necesario que la posición de los entes gubernamentales de nuestros países latinoa- mericanos sea proactiva y orientada a la protección de la salud y la seguridad de la po- blación.

Obstructive sleep apnea (OSA) is a common condition among working-age adults. In today's context, we observe that the retirement age has been extended, with older adults, who have a higher prevalence of OSA, continuing to work even in high-risk situations. One of the main symptoms of OSA is daytime sleepiness, which can directly contribu- te to the risk of accidents, cognitive impairment and reduced work performance. It has also been demonstrated that the reduction of gray matter in the brain, especially in the cerebellum, can lead to coordination and driving capacity impairments. Treatment with positive pressure devices improves work performance and reduces the incidence of traffic accidents, but some cognitive deficits may persist even after months of treatment. Assessing the risk of accidents in drivers is a challenge, and current questionnaires are not suitable for screening. Driving simulators and alertness tests show more promise. The future of research is focused on standardizing simulator outcomes, identifying the best predictors of real-world events, and utilizing artificial intelligence and autonomous vehicles to mitigate risks associated with driver drowsiness. It is imperative that the stance of government entities in our Latin American countries is proactive and aimed at safeguarding the health and safety of the population.

Assessment of obstetric history and cervical length as risk factors for preterm birth / Evaluación de la história obstétrica y la longitud cervical como factores de riesgo para el parto prematuro

Introduction: Preterm birth, before 37 weeks of gestation, is the main determinant of neonatal morbidity and mortality and is associated with serious consequences,including compromised quality of life for the affected individual and physical, psychological, and economic costs. Objective: To evaluate the correlation of obstetric history, cervicovaginal infections, and cervical length with preterm birth. A prospective, blind cohort study evaluated 1,370 pregnant women from Ribeirão Preto between 20 and 25 weeks of gestation. Materials and methods: The correlation between obstetric history, cervical length, and gestational age at birth was obtained by calculating the relative risk of the different variables. Results: The distribution of pregnant women according to cervical length (CL) showed a predominance of women with a cervix longer than 2.5 cm (n = 1,308, 95.8%), followed by women with a cervix between 2 and 2.49 cm (n = 42, 3.1%) and < 2 cm (n = 15, 1.1%). Among the 1,370 pregnant women evaluated, 133 had spontaneous preterm birth (< 259 days); 14 (10.5%) preterm births occurred in women under 19 years of age, 105 (79%) in women between 19 and 35 years, and 14 (10.5%) in women older than 35 years. Microbiological analysis showed the growth of Mycoplasma hominis, Ureaplasma urealyticum, and other bacteria in 8, 17, and 16 women with preterm birth, respectively. Among the 133 women with spontaneous preterm birth, CL was < 2.5 cm in 15 women, < 2 cm in 3, < 1.5 cm in 3, and < 1 cm in 2. Conclusion: The identification of pregnant women at high risk for preterm delivery can reduce the incidence of preterm birth. Although no gold standard test exists for the prediction of preterm birth, this study confirms that the measurement of CL is a good individual predictor.

Introducción: El nacimiento pretérmino, antes de las 37 semanas de gestación, es el principal determinante de la morbimortalidad neonatal y se asocia a graves consecuencias,incluyendo el compromiso de la calidad de vida del individuo afectado y costes físicos, psicológicos y económicos. Objetivo: Evaluar la correlación de los antecedentes obstétricos, infecciones cervicovaginales y longitud cervical con el parto prematuro. Estudio de cohorte prospectivo, ciego, evaluando 1.370 gestantes de Ribeirão Preto entre 20 y 25 semanas de gestación. Material y métodos: La correlación entre los antecedentes obstétricos, la longitud cervical y la edad gestacional al nacer se obtuvo calculando el riesgo relativo de las diferentes variables. Resultados: La distribución de las gestantes según la longitud cervical (LC) mostró un predominio de mujeres con cuello uterino mayor de 2,5 cm (n = 1,308, 95.8%), seguidas de mujeres con cuello uterino entre 2 y 2,49 cm (n = 42, 3.1%) y menor de 2 cm (n = 15, 1.1%). De las 1,370 embarazadas evaluadas, 133 tuvieron un parto prematuro espontáneo (< 259 días); 14 (10.5%) partos prematuros se produjeron en mujeres menores de 19 años, 105 (79%) en mujeres de entre 19 y 35 años, y 14 (10.5%) en mujeres mayores de 35 años. Los análisis microbiológicos mostraron la proliferación de Mycoplasma hominis, Ureaplasma urealyticum y otras bacterias en 8, 17 y 16 mujeres con parto prematuro, respectivamente. Entre las 133 mujeres con parto prematuro espontáneo, la CL fue < 2.5 cm en 15 mujeres, < 2 cm en 3, < 1.5 cm en 3 y < 1 cm en 2. Conclusión: La identificación de las gestantes con alto riesgo de parto prematuro puede reducir la incidencia de parto prematuro. Aunque no existe una prueba de referencia para la predicción del parto prematuro, este estudio confirma que la medición de la longitud cervical es una buena predicción individual.

Standing-Long-Jump Test Application in Identifying Female Adolescents at Risk of Sarcopenic Obesity / Aplicación de la Prueba de Salto de Longitud de Pie para Identificar a Adolescentes con Riesgo de Obesidad Sarcopénica

SUMMARY: The identification of children and adolescents who are at risk of sarcopenic obesity development often requires specialized equipment and expensive test procedures. Therefore, the establishment of cheaper and faster methods would be greatly useful, especially if they could be applied in the field. The study's objective was to establish if identification of female adolescents who suffer the risk of developing sarcopenic obesity can be obtained through the standing-long-jump test application. To achieve the research objectives, various anthropometric and body composition measurements were performed and lower limb explosive strength was assessed using the standing long jump fitness test. The research was conducted on a sample of 535 female respondents randomly selected from 9 elementary schools in the Skopje region of the Republic of North Macedonia. The respondents were divided into quintiles according to BMI z-scores, and the arithmetic means and SD about muscle-to-fat ratio were calculated for each quintile. The cutoff was determined based on the mean and standard deviation of the muscle-to-fat ratio for the 3rd quintile of BMI and the percentage of respondents with sarcopenic obesity was examined. The optimal cut-off value of the long jump fitness test results for predicting sarcopenic obesity in an adolescent girl showed that the area under the ROC curve was 0.781 (95 % CI 0.743-0.815). The standing-long-jump test values, on grounds of odds ratio (OR 95 % CI) about the girls at risk of sarcopenic obesity development, which was identified on muscle-to-fat ratio base, were 8.76 (4.39 - 17.54, p 0.001). It can be used to predict sarcopenic obesity presence in female adolescents, which can be vital in case of health intervention.

La identificación de niños y adolescentes que corren riesgo de desarrollar obesidad sarcopénica a menudo requiere equipos especializados y procedimientos de pruebas costosos. Por lo tanto, el establecimiento de métodos más baratos y rápidos sería de gran utilidad, especialmente si pudieran aplicarse en el campo. El objetivo del estudio fue establecer si la identificación de mujeres adolescentes que sufren riesgo de desarrollar obesidad sarcopénica se puede obtener mediante la aplicación de la prueba de salto de longitud de pie. Para lograr los objetivos de la investigación, se realizaron diversas mediciones antropométricas y de composición corporal y se evaluó la fuerza explosiva de los miembros inferiores mediante la prueba de aptitud de salto de longitud de pie. La investigación se realizó con una muestra de 535 mujeres encuestadas seleccionadas al azar de 9 escuelas primarias de la región de Skopje, en la República de Macedonia del Norte. Los encuestados se dividieron en quintiles según las puntuaciones z del IMC, y se calcularon las medias aritméticas y la DE sobre la relación músculo-grasa para cada quintil. El límite se determinó en función de la media y la desviación estándar de la relación músculo-grasa para el tercer quintil del IMC y se examinó el porcentaje de encuestados con obesidad sarcopénica. El valor de corte óptimo de los resultados de la prueba de condición física de salto de longitud para predecir la obesidad sarcopénica en una adolescente mostró que el área bajo la curva ROC fue 0,781 (IC del 95 %: 0,743-0,815). Los valores de la prueba de salto de longitud de pie, sobre la base del odds ratio (OR IC del 95 %) sobre las niñas en riesgo de desarrollar obesidad sarcopénica, que se identificó sobre la base del ratio músculo-grasa, fueron 8,76 (4,39 - 17,54, p. 0,001). Puede utilizarse para predecir la presencia de obesidad sarcopénica en adolescentes, lo que puede ser vital en caso de intervención sanitaria.

Indice de comorbilidad específico para trasplante alogénico de células progenitoras hematopoyéticas: cohorte retrospectiva de niños y adolescentes con enfermedad maligna / Specific comorbidity index for allogeneic hematopoietic stem cell transplantation: a retrospective cohort of children and adolescents with malignancies

Introducción: Entre las variables que afectan el riesgo de mortalidad relacionada (MRT) al trasplante alogénico de células progenitoras hematopoyéticas (TACPH) se incluyen las comorbilidades previas. Los índices de comorbilidad (IC) buscan mejorar la predicción de eventos combinando factores de riesgo independientes. Objetivos: 1) evaluar el uso de la versión breve y adaptada para niños, adolescentes y adultos jóvenes con enfermedad maligna del índice de comorbilidad específico para trasplante alogénico de células progenitoras hematopoyéticas (smyHCT-CI ); 2) evaluar el uso de los biomarcadores ferritina y albúmina en un índice de comorbilidad ampliado (smyHCT-CIa). Población y métodos: Diseño: cohorte retrospectiva. Periodo 2017- 2022. A cada p se le asignó nuevos puntajes utilizando el smyHCT-CI y el smyHCT-CIa. Los p se clasificaron en grupos de riesgo (GR) bajo (puntaje 0), intermedio (1-2) y alto (>3) con cada índice. Se comparó el n° de p asignado a cada GR grupo de riesgo y la MRT en cada grupo al usar el HCT-CI, el smyHCTCI y el smyHCT-CIa. Resultados: n 75. Frecuencia de p por GR según cada indicador (IC95): HCT-CI bajo 36 (25-47), intermedio 57 (56-69), alto 7 (1-12); smyHCT-CI: bajo 48 (37-59), intermedio 33 (23-44), alto 19 (10-27); smyHCT-CIa: bajo 43 (31-54), intermedio 36 (25-47), alto 21 (12-31). MRT por GR según indicador (IC95): HCT-CI: bajo 6,8 (14-28), intermedio 20,9 (9-33), alto 17,9 (0-55); smyHCT-CIa bajo 12,5 (1-24), intermedio 18,5 (4-33), alto 31,2 (9-54). Conclusión: El smyHCT-CI permitió identificar mejor los pacientes con mayor comorbilidad y riesgo de MRT. La ferritina resultó un biomarcador útil en la estimación del riesgo de MRT (AU)

Introduction: Variables affecting allogeneic hematopoietic stem cell transplantation (HCT) related mortality risk (TMR) include prior comorbidities. Comorbidity indices (CI) aim to improve event prediction by combining independent risk factors. Objectives: 1) to evaluate the use of the brief and adapted version of the HCT-specific comorbidity index for children, adolescents and young adults with malignancies (ymHCT-CI); 2) to evaluate the use of the biomarkers ferritin and albumin in an expanded comorbidity index (expanded ymHCT-CI). Population and methods: Design: retrospective cohort. Period 2017- 2022. Each patient was assigned new scores using the ymHCTCI and expanded ymHCT-CI. The p were classified into low (score 0), intermediate (1-2) and high (>3) risk groups (RG) with each index. The number of patients assigned to each RG and the TMR in each group were compared using the HCTCI, the ymHCT-CI, and the expanded ymHCT-CI. Results: n 75. Frequency of patients per RG according to each indicator (95%CI): HCT-CI low 36 (25-47), intermediate 57 (56-69), high 7 (1-12); ymHCT-CI: low 48 (37-59), intermediate 33 (23-44), high 19 (10-27); expanded ymHCT-CI: low 43 (31-54), intermediate 36 (25-47), high 21 (12-31). TMR by RG according to indicator (95%CI): HCT-CI: low 6.8 (14-28), intermediate 20.9 (9-33), high 17.9 (0-55); expanded ymHCT-CI low 12.5 (1-24), intermediate 18.5 (4-33), high 31.2 (9-54). Conclusion: ymHCT-CI allowed better identification of patients with higher comorbidity and risk of TMR. Ferritin proved to be a useful biomarker to estimate TMR risk (AU)

Distribución de genotipos de virus papiloma humano de alto riesgo en mujeres y hombres atendidos en una red asistencial privada en la Región Metropolitana, Chile / Distribution of high-risk human papillomavirus genotypes in women and men attended in a private healthcare network in the Metropolitan Region, Chile

Introducción: La infección persistente por genotipos de virus papiloma humano de alto riesgo (VPH-AR) es la principal causa del cáncer cérvico-uterino en todo el mundo. Los genotipos 16 y 18 están asociados a la progresión hacia el cáncer de cuello uterino; sin embargo, otros genotipos también presentan alto riesgo oncogénico. Existe escasa evidencia respecto a la distribución de genotipos VPH-AR en la población nacional, siendo un tema que debiese ser abordado en el contexto de un creciente aumento de la inmigración e implementación del programa de inmunización en Chile desde 2015. Objetivo: Dar a conocer la distribución de genotipos de VPH-AR detectados en pacientes de ambos sexos, atendidos en la red de atención privada de Clínica Dávila de Santiago, entre los años 2014 y 2021. Metodología: Se estudiaron muestras genitales y anales provenientes de 3.642 pacientes, incluyendo ambos sexos. La genotipificación fue realizada mediante reacción de la polimerasa en cadena (RPC) en tiempo real (HPV AnyplexTM II HPV28 detection, Seegene, Korea. Resultados: La distribución global de genotipos en mujeres (porcentaje) fue: 16 (14,34%) - 31 (6,20%) - 39 (5,94%) - 58 (5,94%) - 51 (5,68%) - 53 (5,64%) - 52 (5,30%) - 56 (5,27%) - 68 (5,19%) - 66 (4,97% - 18 (3,36%) - 59 (3,29%) - 73 (2,80%) - 35 (2,54%) - 45 (2,13%) - 33 (1,53%) - 82 (1,38%) - 26 (0,49%) y 69 (0,41%). En hombres fue: 16 (8,52%) - 58 (4,39%) - 51 (8,44%) - 26 (0,42%) - 18 (3,21%) - 52 (4,47%) - 39 (5,40%) - 53 (4,56%) - 33 (1,69%) - 35 (2,03%), 73 (2,19%) - 69 (0,59%) - 45 (2,11%) - 59 (4,22%) - 68 (3,04%) - 66 (5,06%) - 31 (4,64%) - 56 (4,81%) y 82 (1,10%). Conclusiones: La distribución de los genotipos de VPH fue concordante con estudios previos nacionales. Se observó una tendencia a la reducción del genotipo 16 en el tiempo, lo cual podría relacionarse a la vacunación, implementada en los últimos años en Chile. Destaca que otros genotipos de VPH-AR tuvieron una alta frecuencia en la población estudiada por lo que sería recomendable evaluar la pesquisa ampliada de genotipos de VPH-AR para valorar el riesgo oncogénico, con fines diagnósticos y terapéuticos.

Background: Persistent infection by high-risk human papillomavirus (HR-HPV) genotypes is the main cause of cervical cancer worldwide. Genotypes 16 and 18 are associated with progression to cervical cancer, however other genotypes also present high oncogenic risk. There is little evidence regarding the distribution of HR-HPV genotypes in the national population, being an issue that should be addressed in the context of a growing increase in immigration and implementation of the immunization program in Chile since 2015. Aim: To show the distribution of HR-HPV genotypes detected in women and men, attended at the private care network of Clinica Davila, Santiago City, between 2014 and 2021. Methods: Genital and anal samples from 3,642 patients were studied, including both sexes. Genotyping was performed by real-time polymerase chain reaction (PCR) (HPV AnyplexTM II HPV28 detection, Seegene, Korea). Results: The global distribution of genotypes in women (percentage) was: 16 (14.34%) - 31 (6.20%) - 39 (5.94%) - 58 (5.94%) - 51 (5.68%) - 53 (5.64%) - 52 (5.30%) - 56 (5.27%) - 68 (5.19%) - 66 (4.97%) - 18 (3.36%) - 59 (3.29%) - 73 (2.80%) - 35 (2.54%) - 45 (2.13%) - 33 (1.53%) - 82 (1.38%) - 26 (0.49%) and 69 (0.41%). In men was: 16 (8.52%) - 58 (4.39%) - 51 (8.44%) - 26 (0.42%) - 18 (3.21%) - 52 (4.47%) - 39 (5.40%) - 53 (4.56%), 33 (1.69%) - 35 (2.03%) - 73 (2.19%) - 69 (0.59%) - 45 (2.11%) - 59 (4.22%) - 68 (3.04%) - 66 (5.06%) - 31 (4.64%) - 56 (4.81%) and 82 (1.10%). Conclusions: The distribution of HPV genotypes was consistent with previous national studies. A tendency to reduce genotype 16 over the years was observed, which could be related to the vaccination, implemented in recent years in Chile. It is remarkable that other HR-HPV genotypes had a high frequency in the population studied, so it would be advisable to evaluate an expanded screening for HR-HPV genotypes to assess the oncogenic risk, for diagnostic and therapeutic purposes.

El puntaje de Framingham ayudaría en la estratificación del riesgo de pacientes con ergometría positiva y SPECT normal / The Framingham score could help in risk stratification of patients with positive ergometry and normal SPECT

Antecedentes. El valor pronóstico de una ergometría positiva en el contexto de imágenes tomográficas de perfusión miocárdica de estrés y reposo (SPECT) normales no está bien establecido. Objetivos. Documentar la incidencia de infarto, muerte y revascularización coronaria en pacientes con una ergometría positiva de riesgo intermedio e imágenes de perfusión SPECT normales, y explorar el potencial valor del puntaje de riesgo de Framingham en la estratificación pronóstica de estos pacientes. Métodos. Cohorte retrospectiva integrada por pacientes que habían presentado síntomas o hallazgos electrocardiográficos compatibles con enfermedad arterial coronaria durante la prueba de esfuerzo, con criterios de riesgo intermedio en la puntuación de Duke y perfusión miocárdica SPECT normal. Fueron identificados a partir de la base de datos del laboratorio de cardiología nuclear del Instituto de Cardiología y Cirugía Cardiovascular de la ciudad de Posadas, Argentina. Resultados. Fueron elegibles 217 pacientes. El seguimiento fue de 3 1,5 años. La sobrevida libre de eventos (muerte,infarto de miocardio no fatal, angioplastia coronaria o cirugía de bypass de arteria coronaria) a uno, tres y cinco años fue significativamente menor (Log-rank test, p= 0,001) en el grupo con puntaje de Framingham alto o muy alto (77, 71y 59 %, respectivamente) que en el grupo de puntaje bajo o intermedio (89, 87 y 83 %). Tomando como referencia a los pacientes con riesgo bajo en el puntaje de Framingham, luego de ajustar por edad, sexo y puntaje de Duke, los pacientes categorizados en los estratos alto y muy alto riesgo del puntaje de Framingham presentaron una incidencia del evento combinado cercana al triple (hazard ratio [HR] 2,81; intervalo de confianza [IC] del 95 % 0,91 a 8,72; p= 0,07 y HR 3,61;IC 95 % 1,23 a 10,56; p= 0,019 respectivamente). Conclusiones. La estimación de riesgo con el puntaje de Framingham sería de ayuda en la estratificación pronóstica de los pacientes con ergometría positiva y SPECT normal. (AU)

Background. The prognostic value of positive exercise testing with normal SPECT myocardial perfusion imaging is not well established. Objectives. To document the incidence of infarction, death, and coronary revascularization in patients with a positive intermediate-risk exercise test and normal SPECT perfusion images and to explore the potential value of the Framingham Risk Score in the prognostic stratification of these patients. Methods. A retrospective cohort comprised patients who presented symptoms or electrocardiographic findings compatible with coronary artery disease during the stress test, with intermediate risk criteria in the Duke score and normal SPECT myocardial perfusion. They were identified from the database of the nuclear cardiology laboratory of the Instituto de Cardiología y Cirugía Cardiovascular of Posadas, Argentina. Results. 217 patients were eligible. Follow-up was 3 1.5 years. Event-free survival (death, non-fatal myocardial infarction, coronary angioplasty, or coronary artery bypass surgery) at one, three, and five years was significantly lower (Log-ranktest, p: 0.001) in the group with a score of Framingham high or very high (77, 71 and 59 %, respectively) than in the lowor intermediate score group (89, 87 and 83 %). Taking as reference the low-risk patients in the Framingham score, after adjusting for age, sex, and Duke score, the patients categorized in the high-risk and very high-risk strata showed about three times higher incidence of the combined event (hazard ratio [HR] 2.81; 95 % confidence interval [CI] 0.91 to 8.72;p=0.07 and HR 3.61; 95 % CI 1.23 to 10.56; p=0.019 respectively). Conclusions. Risk estimation with the Framingham score would be helpful in the prognostic stratification of patients with positive exercise testing and normal SPECT. (AU)

El dilema clínico frente a los pacientes con ergometría positiva y prueba de perfusión miocárdica con SPECT normal / The clinical dilemma facing patients with positive stress test and normal SPECT myocardial perfusion imaging

La evaluación de la perfusión miocárdica con SPECT combina una prueba de esfuerzo (ergometría o estrés farmacológico) junto a imágenes de perfusión con radioisótopos. Este estudio es útil para establecer el diagnóstico de enfermedad arterial coronaria, estratificar el riesgo de infarto y tomar decisiones terapéuticas. Un resultado normal aporta un alto valor predictivo negativo, es decir, una muy baja probabilidad de que el paciente presente eventos cardiovasculares. El hallazgo de signos de isquemia en la ergometría podría poner en jaque el valor predictivo negativo de una perfusión normal. En presencia de este resultado, el paso siguiente es evaluar los predictores de riesgo en la ergometría, el riesgo propio del paciente en función de los antecedentes clínicos y el puntaje cálcico coronario, cuando este se encuentra disponible. Ante la presencia concomitante de otros marcadores de riesgo se sugiere completar la evaluación con un estudio anatómico.El uso de nuevas tecnologías podría mejorar la precisión en la predicción de eventos. (AU)

Assessment of myocardial perfusion with SPECT combines a stress test (ergometry or pharmacological stress) with radioisotope perfusion imaging. This test is helpful to diagnose coronary artery disease, stratify the risk of heart attack, and make therapeutic decisions. A normal result provides a high negative predictive value; therefore, the probability of cardiovascular events is very low. Signs of ischemia on an ergometry could jeopardize the negative predictive value of normal perfusion. In this clinical setting, the next step is to evaluate the risk predictors in the stress test, the individual risk based on the clinical history, and the coronary calcium score when available. Given the simultaneous presence of other risk markers,completing the evaluation with an anatomical study is suggested. The use of new technologies could improve the accuracy of event prediction.

Avaliação de risco agudo à exposição dietética a resíduos de agrotóxicos em tomate / Acute risk assessment of dietary exposure to pesticide residues in tomato

A utilização de agrotóxicos ao redor do mundo é elevada, estimada em mais 2 milhões de toneladas e somente o continente americano emprega 1,2 milhão de toneladas de produtos. O Brasil possui na agricultura a sua principal atividade econômica e utilizou em 2021 aproximadamente 700 mil toneladas de agrotóxicos. O tomate é um dos vegetais mais cultivados e consumidos no mundo e o Brasil figura como o 10º maior produtor. O consumo anual médio de tomate do brasileiro é de 4,2 kg, é um vegetal nutritivo e com propriedades associadas à prevenção de câncer. O tomate é uma das culturas com maior uso de agrotóxicos e durante o período desse estudo, era autorizado o uso de 123 agrotóxicos. Os resíduos desses produtos nos alimentos podem acarretar em diversos problemas à saúde, mesmo em curta exposição (< 24h). Desse modo, uma das maneiras de garantir a segurança alimentar da população é a realização da avaliação de risco de contaminação dietética. No processo de validação 73 ingredientes ativos respeitaram os critérios do protocolo adotado. Para a realização da estimativa de risco de exposição dietética aguda, foram coletadas 30 amostras de tomate in natura e 11 de tomate pelado, entre setembro de 2021 e março de 2022. Para a extração dos compostos de interesse foi utilizado o método QuEChERS e para avaliação dos resíduos, a cromatografia líquida acoplada à espectrometria de massas. Das amostras de tomate in natura, somente seis (20 %) estavam isentas dos compostos pesquisados; 18 (60 %) apresentaram resíduo(s) abaixo do limite (LMR) estabelecido e seis amostras (20 %) foram consideradas impróprias ao consumo. Das amostras de tomate pelado, três estavam isentas dos agrotóxicos pesquisados e oito (72 %) apresentaram resíduo de carbendazim abaixo do LMR. Nenhuma das amostras mostrou potencial de contaminação aguda por agrotóxicos, apesar disso não é possível afirmar que não há risco, pois não há como estimar os potenciais efeitos adversos provenientes do consumo de um alimento com múltiplos compostos.

More than 2 million tons of pesticide products are used annually through the world and only the America continent was used 1,2 million tons of these products. The agriculture is the main economic activity in Brazil, this way in 2021 approximately 700 thousand tons of pesticide were applied in its crops. Tomato is one of the most cultivated and consumed vegetables in the world and Brazil is the 10th largest producer. The Brazilian people consumes an average of 4.2 kg of tomatoes by year, it is a nutritious vegetable with anti-cancer properties. Tomato crop is one of the which highest pesticide usages, during this study 123 compounds were permitted for this crop. Pesticide residues in food may causes several health problems, even in short-term exposition (< 24h), thus one of the ways to ensure the food safety to population is performing the dietary contamination risk assessment. In the validation process 73 active ingredients were within the established criteria. To perform the acute risk assessment of dietary exposure, were collected samples of: fresh tomato (30) and whole peeled tomato (11) in between September of 2021 and March of 2022. To extraction of interest substances was used the QuEChERS method and to residue evaluation the liquid chromatography coupled to mass spectrometry. Of the fresh tomato samples, only six (20 %) were free of searched analytes; 18 (60 %) showed residue(s) bellow the established limits (MRL) and six (20 %) were considered unfit to consumption. Of the whole peeled tomato samples, three were free of searched substances and eight (72 %) showed residue of carbendazim bellow the MRL. None of the samples showed potential for acute contamination by pesticide, however it is not possible to say that there is no risk, as there is no way to estimate the potential adverse effects on health arising from the consumption of a food with several compounds.

Strategies and advances in laboratory tests for primary liver cancer / 中华预防医学杂志

Primary liver cancer is one of the leading causes of cancer-related deaths worldwide, its early diagnosis and early treatment are of great clinical importance. The main detection tools for liver cancer include serological indicators, imaging tests and risk assessment models. With the advancement of technology and research, the sensitivity and specificity of laboratory tests for liver cancer have been substantially improved, but there are still false negatives and low rates of early diagnosis. For different causes and prevalence regions, each country has developed its clinical practice guidelines to guide risk groups for effective prevention, early diagnosis and standardized treatment. It is important to establish a liver cancer diagnosis strategy that is suitable for China's national conditions, concerning the guidelines for the vigilance and prevention of liver cancer. In this article, the advantages and disadvantages of liver cancer-related tests and the impact of future development trends on laboratory strategies are explained from the perspective of laboratory testing strategies, to provide theoretical support for the practical application of liver cancer diagnostic strategies.

Multivariate guard-bands and total risk assessment on multiparameter evaluations with correlated and uncorrelated measured values

Abstract The quality, efficacy, and safety of medicines are usually verified by analytical results. Measurement uncertainty is a critical aspect for the reliability of these analytical results. The pharmacopeial compendia usually adopt a simple acceptance rule that does not consider information from measurement uncertainty. In this work, we compared decision-making using simple acceptance and decision rules with the use of guard-band for multiparameter evaluation of ofloxacin ophthalmic solution and acyclovir topical cream. Ciprofloxacin ophthalmic solution and acyclovir topical cream samples were subject to pharmacopeial tests and assays. Multivariate guard-band widths were calculated by multiplying the standard uncertainty (u) by an appropriate multivariate coverage factor (k'). The multivariate coverage factor (k') was obtained by the Monte Carlo method. According to the simple acceptance rule, all the results obtained for ciprofloxacin ophthalmic solution and acyclovir topical cream are within the specification limits. However, the risk of false conformity decisions increases for ciprofloxacin tests. Decisions made using the simple acceptance rule and decision rules with the use of guard-band may differ. The simple acceptance rule may increase the risk of false conformity decisions when the measured value is close to the regulatory specification limits and/or when the measurement uncertainty value is inappropriately high. Nevertheless, the guard-band decision rule will always reduce the risk of false conformity decisions. Therefore, using information on measurement uncertainty in conformity assessment is highly recommended to ensure the proper efficacy, safety, and quality of medicines.

Introdução: Diabéticos podem apresentar perda de força e massa muscular de forma acentuada. Assim, as triagens SARC-F e SARC-CALF são úteis na investigação do risco de sarcopenia. Objetivo: Associar o risco de sarcopenia em pacientes diabéticos com as variáveis sociodemográficas, econômicas, clínicas, antropométricas e de estilo de vida. Método: Estudo do tipo série de casos realizado com adultos diabéticos tipo 2, de ambos os sexos, com idade entre 20 e 59 anos. A avaliação do risco de sarcopenia se deu pela aplicação dos questionários SARC-F e SARC-CALF. Para caracterização da amostra e associação com o risco de sarcopenia, foram coletados dados sociodemográficos e econômicos, medidas antropométricas, condições clínicas e estilo de vida. Resultados: A amostra foi composta por 69 pacientes, com média de idade de 53±7,5 anos e maior proporção de mulheres (63,8%; IC95%: 50,7-75,4). A frequência do risco positivo para sarcopenia segundo o SARC-F e o SARC-CALF foi de 43,48% e 46,38%, respectivamente. O SARC-F não mostrou associação significativa com as variáveis estudadas; já o SARC-CALF associou-se com índice de massa corporal (p <0,001), circunferência da cintura (p <0,001) e hábito de fumar (p = 0,027). Conclusão: O risco de sarcopenia foi observado em aproximadamente metade dos pacientes avaliados. O instrumento SARC-CALF apresentou associação com as variáveis antropométricas e o hábito de fumar, podendo ser considerado satisfatório para avaliar o risco de sarcopenia e intervir de forma precoce e efetiva.

Introduction: Individuals with diabetes often experience an accentuated loss of muscle mass and strength. Thus, the SARC-F and SARC-CALF screening tools are useful for the investigation of the risk of sarcopenia. Objective: Associate the risk of sarcopenia with sociodemographic, economic, clinical, anthropometric and lifestyle variables in individuals with diabetes. Methods: A case-series study was conducted involving male and female adults with type 2 diabetes between 20 and 59 years of age. The assessment of the risk of diabetes was performed using the SARC-F and SARC-CALF instruments. Data were collected on sociodemographic-economic variables, anthropometric measures, clinical conditions and lifestyle for the characterization of the sample and to test associations with the risk of sarcopenia. Results: The sample was composed of 69 patients, with a mean age of 53 ± 7.5 years and a predominance of women (63.8%; 95%CI: 50.7-75.4). The prevalence of risk of sarcopenia was 43.48% and 46.38% based on the SARC-F and SARC-CALF, respectively. Using the SARC-F, no significant associations were found with the variables of interest. Using the SARC-CALF, however, the risk of sarcopenia was associated with body mass index (p < 0.001), waist circumference (p < 0.001) and smoking habit (p = 0.027). Conclusion: Approximately half of the individuals analyzed were at risk of sarcopenia. The SARC-CALF questionnaire was associated with anthropometric variables and the smoking habit and can be considered adequate for the assessment of the risk of sarcopenia, enabling early, effective interventions.

Consideraciones médico-legales laborales de la fórmula de Balthazard / Occupational medical-legal considerations of the Balthazard formula

La determinación del porcentaje de pérdida en pacientes lesionados con múltiples secuelas por riesgos de trabajo resulta un verdadero reto para el perito, esto adquiere mayor relevancia cuando en el fuero judicial se pueden presentar discrepancias en los criterios para el uso o no de fórmulas matemáticas para el cálculo. La fórmula de suma combinada, creada por el Médico Forense Víctor Balthazard, no es más que un ordenamiento de una regla de tres que ordena los porcentajes otorgados a cada secuela de mayor a menor para evitar que el porcentaje final sobrepase el 100%, o bien que resulte en un porcentaje mayor que una secuela única puntuada en el baremo y que por gravedad en la intensidad de la misma resulte con un porcentaje menor al calculado por la secuela múltiple y que se ha utilizado en fueros laborales y de seguridad social alrededor del mundo. El Baremo contenido en el Código de Trabajo no establece explícitamente la forma en que se calcula el porcentaje de pérdida por secuelas múltiples, lo cual brinda libertad al perito para utilizar fórmulas, como lo es la fórmula de suma combinada, que permite calcular de forma congruente las pérdidas sucesivas sin sobrepasar a la persona más allá de su capacidad general total del 100% o de otorgar porcentajes mayores a secuelas de mayor gravedad que la suma de las pérdidas por el evento que se está valorando.

The determination of the percentage of loss in injured patients with multiple sequelae due to occupational hazards is a real challenge for the expert, this becomes even more relevant when in the judicial system there may be discrepancies in the criteria for the use or not of mathematical formulas for the calculation. The combined sum formula, created by the Forensic Physician Victor Balthazard, is nothing more than an arrangement of a rule of three that orders the percentages given to each sequel from highest to lowest to avoid that the final percentage exceeds 100%, or that it results in a higher percentage than a single sequel scored in the scale and that due to the severity in the intensity of the same results in a lower percentage than that calculated for the multiple sequel and that has been used in labor and social security courts around the world. The Schedule contained in the Labor Code does not explicitly establish the way in which the percentage of loss for multiple sequelae is calculated, which gives the expert the freedom to use formulas, such as the combined sum formula, which allows a congruent calculation of the successive losses without exceeding the person's total general capacity of 100% or to grant higher percentages to sequelae of greater severity than the sum of the losses for the event being valued.

Objetivo: Analisar o impacto da pandemia de COVID-19 no excesso do risco de morrer no Brasil em 2020. Métodos: Estudo ecológico do tipo exploratório, com dados de óbitos por todas as causas de morte do Painel de Monitoramento da Mortalidade do Ministério da Saúde. Calcularam-se taxas brutas e razões de taxas (RT) de mortalidade por todas as causas segundo os capítulos da causa básica de morte, sexo e faixa etária. Verificou-se associação estatística por meio do teste qui-quadrado de Mantel Haenszel quando p<0,05. Resultados: Houve aumento no risco de morrer de 13% em 2020. As regiões com maior incremento na taxa demortalidade foram Norte (RT=1,24; IC95%: 1,23-1,26), Centro-Oeste (RT=1,17; IC95%: 1,16-1,18) e Nordeste (RT=1,15; IC95%: 1,14-1,15). O excesso no risco de morrer foi maior no sexo masculino, na região Norte, por doenças infecciosas e parasitárias, incluindo a COVID-19 (RT=4,58; IC95%: 4,53-4,62), seguida de causas mal definidas (RT=1,33; IC95%: 1,32-1,34), gravidez, parto e puerpério (RT=1,17; IC95%: 1,10-1,25). Conclusão:O excesso de risco de morrer possibilitou reconhecer a magnitude e o impacto da COVID-19 no país e pode subsidiar as autoridades de saúde na organização de ações voltadas para a diminuição dos efeitos dessa emergência de saúde pública.

Objective: To analyze the impact of the COVID-19 pandemic on the excess risk of dying in Brazil in 2020. Methods:An ecological study of the exploratory type conducted with data on deaths due to all causes from the Ministry of Health's Mortality Monitoring Panel. Unadjusted rates and rate ratios (RR) of all-cause mortality were calculated according to underlying cause of death, gender and age group. A statistical association was verified by means of the Mantel Haenszel chi-square test when p<0.05. Results:There was a 13% increase in the risk of dying in 2020. The regions with the highest increase in the mortality rate were North (RR=1.24; 95%CI: 1.23-1.26), Midwest (RR=1.17; 95%CI: 1.16-1.18) and Northeast (RR=1.15; 95%CI: 1.14-1.15). Excess risk of dying was higher in males, in the North region, due to infectious and parasitic diseases, including COVID-19 (RR=4.58; 95%CI: 4.53-4.62), followed by ill-defined causes (RR=1.33; 95%CI: 1.32-1.34) and by pregnancy, delivery and puerperium (RR=1.17; 95%CI: 1.10-1.25). Conclusion: Excess risk of dying allowed recognizing the magnitude and impact of COVID-19 in the country and can support health authorities in organizing actions aimed at reducing the effects of this public health emergency.

Cirugía coronaria sin circulación extracorpórea / Coronary artery revascularization performed without extracorporeal circulation

La cirugía de revascularización coronaria (CABG) es el estándar de tratamiento para la revascularización de la enfermedad de la arteria coronaria izquierda y/o de tres vasos. La cirugía coronaria sin bomba (OPCAB) evita el uso de derivación cardiopulmonar y puede mejorar los resultados a largo plazo al reducir las tasas de lesión miocárdica perioperatoria, accidente cerebrovascular (ACV), deterioro neurocognitivo y mortalidad de causa cardiaca. En la actualidad, se han llevado a cabo diversos ensayos clínicos desde la popularización del OPCAB en la década de los 90. Sin embargo, hasta el momento no se ha demostrado ningún beneficio del OPCAB en comparación con la cirugía tradicional a pesar de las reducciones favorables a corto plazo en los requerimientos de transfusión y otras complicaciones postoperatorias. Además, OPCAB se asocia con una revascularización miocárdica menos eficaz y no previene por completo las complicaciones tradicionalmente asociadas con la circulación extracorpórea (CEC). Este artículo revisa la evidencia actual de OPCAB en comparación con CABG tradicional en cuanto a los resultados clínicos a corto y largo plazo. Se analizan los resultados de la cirugía coronaria sin circulación extracorpórea (CEC) , comparándola con la cirugía convencional (con CEC). La revascularización coronaria sin CEC presenta resultados similares a la convencional, siempre que se cumplan determinadas condiciones en la selección de los pacientes. Una de ellas, muy importante, es la mayor experiencia del cirujano con el procedimiento.

The results of coronary artery revascularization performed without extracorporeal circulation (off pump) are compared to those of the traditional ("on pump") procedure. Compliance with selective conditions are required to obtain similar results. The most important being the experience of the surgeon performing the off pump procedure.
