Prevalência de fissuras labiopalatais no Brasil e sua notificação no sistema de informação / Prevalence of cleft lip and palate in Brazil and its notification in the information system

Introdução: A fissura labiopalatina é a deformidade congênita mais comum, com uma incidência de 1,53/1000 nascidos vivos e o tratamento predominantemente realizado no Sistema Único de Saúde (SUS). Em 1999, o Sistema de Informações sobre Nascidos Vivos (SINASC) implantou a lacuna para preenchimento referente a deformidade congênita. Trabalhos vêm demostrando a subnotificação importante da fissura no SINASC. Método: Foi levantado o número de crianças nascidas por ano no Brasil entre 2012 e 2018 nas respectivas regiões, projetando o número de fissurados nascidos por ano usando a proporção 1,53/1000 nascidos vivos. A partir destes dados, observado o número de fissurados notificados no sistema SUS e comparado com a projeção feita observando uma estimativa de notificação por região. Verificada também a evolução dos gastos governamentais por região com cirurgia de fissura labiopalatina no período de 2012 a 2018. Resultados: Houve uma notificação de 54,1% a 36,7% das crianças nascidas com fissura, sendo a Região Sudeste com melhor índice e o Nordeste com o índice mais baixo de notificação. Os gastos federais em cirurgia de fissura labiopalatina diminuíram entre 2012 e 2018, frente ao número de nascimentos com fissuras, que se manteve estável neste período. Conclusão: Apesar do SINASC ser uma ferramenta importante, as subnotificações expressivas desta afecção impactam nas políticas públicas, pois utilizam dados inconsistentes com a realidade. Outra preocupação é a diminuição dos gastos federais com cirurgias de fissurados, o que demostra que mais crianças estão deixando de receber tratamento adequado.

Introduction: Cleft lip and palate is the most common congenital deformity, with an incidence of 1.53/1000 live births, and treatment is predominantly carried out in the Unified Health System (Sistema Único de Saúde SUS). In 1999, the Live Birth Information System (Sistema de Informações sobre Nascidos Vivos SINASC) implemented the gap to be filled in regarding congenital deformities. Studies have demonstrated the significant underreporting of the fissure in SINASC. Method: The number of children born per year in Brazil between 2012 and 2018 was surveyed in the respective regions, projecting the number of cleft children born per year using the proportion 1.53/1000 live births. From these data, the number of cleft patients notified in the SUS system was observed and compared with the projection made by observing an estimate of notification by region. The evolution of government spending by region on cleft lip and palate surgery in the period from 2012 to 2018 was also verified. Results: There was a notification of 54.1% to 36.7% of children born with cleft, with the Southeast Region having the best rate and the Northeast with the lowest notification rate. Federal spending on cleft lip and palate surgery decreased between 2012 and 2018, compared to the number of births with clefts, which remained stable during this period. Conclusion: Although SINASC is an important tool, the significant underreporting of this condition impacts public policies, as it uses data inconsistent with reality. Another concern is the decrease in federal spending on cleft surgery, which shows that more children are failing to receive adequate treatment.

Prevalencia y análisis clinicopatológico de pacientes con mutación en el gen PIK3CA con cáncer de mama avanzado Rh+/Her2- en el Instituto Oncológico Nacional De Panamá

Antecedentes: La vía de señalización de la fosfoisitol 3-quinasa (PI3K), que promueve el crecimiento y el metabolismo de las células cancerosas, es la vía mutada con mayor frecuencia en el cáncer de mama y es asociada con quimio resistencia y mal pronóstico. En este estudio presentamos el primer análisis en población panameña y de la región, con ataciones precisas de la mutación PIK3CA, las características clinicopatológicas y pronóstico. Métodos: Estudio exploratorio, donde se recolectaron prospectivamente tumores de 74 pacientes con cáncer de mama metastásico RH+/Her2- del Instituto Oncológico Nacional entre 2022 y 2023. Se realizó un ensayo de PCR en tiempo real para análisis de mutación en ADN extraído del material tumoral fijado en formalina e incluido en parafina para detectar mutaciones en los exones 1, 4, 7, 9 y 20 del gen PIK3CA. Resultados: La mediana de edad de las pacientes estudiadas fue 59 años. La mutación en PIK3CA se encontró en 33.8% (25/74) de pacientes con cáncer de mama, entre ellas 44% fueron mutaciones en el exón 20, 38% en el exón 9, 13% en el exón 4 y 5% en el exón 1. Se observó una correlación significativa entre la mutación y el  tener historia de cáncer en la familia (p= 0.005), y en pacientes postmepáusicas (P = 0.045).  encontramos asociación entre la mutación y el tipo histológico, grado, tamaño tumoral ni estatus axilar al momento del diagnóstico. La mediana de supervivencia libre de progresión  se alcanzó en ambos grupos y tampoco demostró una diferencia significativa. Conclusión: La prevalencia de la mutación es relativamente alta comparada con escenarios internacionales, puede ofrecer una ventaja para elegir las mejores opciones de tratamiento por lo que debe evaluarse de forma rutinaria durante las intervenciones clínicas.

Background: The phosphoisitol 3-kinase (PI3K) signaling pathway, which promotes cancer cell growth and metabolism, is the most frequently mutated pathway in breast cancer and is associated with chemoresistance and poor progsis. In this study we present the first analysis in Panamanian and regional population, with precise antations of the PIK3CA mutation, clinicopathological characteristics and progsis. Methods: Exploratory study, where tumors were prospectively collected from 74 patients with RH+/Her2- metastatic breast cancer from the Instituto Oncológico Nacional between 2022 and 2023. A real-time PCR assay for mutation analysis was performed on DNA extracted from formalin-fixed, paraffin-embedded tumor material to detect mutations in exons 1, 4, 7, 9 and 20 of the PIK3CA gene. Results: The median age of the patients studied was 59 years. The mutation in PIK3CA was found in 33.8% (25/74) of patients with breast cancer, among them 44% were mutations in exon 20, 38% in exon 9, 13% in exon 4 and 5% in exon 1. A significant correlation was observed between the mutation and having  history of cancer in the family (P = 0.005), and in postmepausal patients (P = 0.045). We found  association between the mutation and histologic type, grade, tumor size or axillary status at diagsis. Median progression-free survival was t reached in both groups and did t show a significant difference. Conclusion: The prevalence of the mutation is relatively high compared to international settings, it may offer an advantage in choosing the best treatment options and should be routinely evaluated during clinical interventions.

Dental Loss in the Lower Socioeconomic Stratum of a Sample of the Chilean Population Born in the 19TH and 20TH Centuries

SUMMARY: Partial or total dental loss (edentulism) is associated with decreased quality of life. Chile has large socioeconomic gaps, which are also recognized in oral health, but it is not known how Edentulism has evolved throughout the country. The aim of this study was to determine the edentulism in people born during the 19th and 20th centuries in Chile, who died in the 20th century, and to compare it with current data from the Chilean Ministry of Health (MINSAL) to observe its evolution in the country. For this purpose, 60 3D models of skulls from the Subactual Osteological Collection of Santiago were analyzed (30 individuals per sex), in which the presence and absence of teeth in antemortem in the maxilla were analyzed. A high percentage of tooth loss was observed, with 65 % partial edentulism, a 30 % total edentulism, and only 5 % had complete dentition in this osteological collection. In addition, a significant decrease over time was found; in 2017, the percentage of complete dentition at the national level was 32.8 %. A higher frequency of edentulism was also found in females from the osteological collection, with a significant probability of twice as much edentulism as in males. However, this sex difference was smaller than those found in the current study. Our study is the first to compare edentulism in Chile in two different time periods, since, in addition to studying it in the 19th and 20th century, it is carried out with data from the present day and in line with previous research, reveals the importance of socioeconomic and sex variables for dental loss.

La pérdida parcial o total de dientes (edentulismo) se asocia a una disminución de la calidad de vida. Chile tiene grandes brechas socioeconómicas, que también se reconocen en la salud oral, pero se desconoce cómo ha evolucionado el edentulismo en el país. El objetivo de este estudio fue determinar el edentulismo en personas nacidas durante los siglos XIX y XX en Chile y fallecidas en el siglo XX, y compararlo con datos actuales del Ministerio de Salud de Chile (MINSAL) para observar su evolución en el país. Para ello, se analizaron 60 modelos 3D de cráneos de la Colección Osteológica Subactual de Santiago (30 individuos por sexo), en los que se analizó la presencia y ausencia de dientes en dentición antemortem en el maxilar. Se observó un alto porcentaje de pérdida dentaria, con un 65 % de edentulismo parcial y un 30 % de edentulismo total, y sólo un 5 % presentaba dentición completa en esta colección osteológica. Además, se encontró una disminución significativa a lo largo del tiempo; en 2017, la dentición completa a nivel país fue del 32,8 %. También se encontró una mayor frecuencia de edentulismo en las mujeres de la colección osteológica, con una probabilidad significativa del doble de edentulismo que en los hombres. Sin embargo, esta diferencia de sexo fue menor que la hallada en datos actuales. Este estudio es el primero que compara el edentulismo en Chile en dos épocas diferentes, ya que además de estudiarlo en los siglos XIX y XX, se realizó con datos de la actualidad y, en línea con investigaciones previas, revela la importancia de las variables socioeconómicas y de sexo en la pérdida dental.

Caracterización de la conducta suicida en población general de la Región de Coquimbo (Chile) entre 2018 y 2020 / Characterization of suicidal behavior in Coquimbo, Chile, between 2018 and 2020

Introducción La conducta suicida es un problema de salud pública mundial. La Organización Mundial de la Salud estimó en 700 000 los fallecimientos por suicidio para el año 2021. Objetivo El propósito fue estimar la prevalencia de la conducta suicida y describir sus factores relacionados en la Región de Coquimbo, Chile, entre los años 2018 y 2020. Métodos Se analizaron 2190 notificaciones por intentos suicidas del sistema de vigilancia epidemiológica regional, que correspondieron a 1781 personas; junto con 217 informes de personas fallecidas por suicidio del Servicio Médico Legal. Resultados La tasa global de suicidio para la región en el período fue de 9,79 fallecimientos por 100 000 habitantes. Se estandarizaron las tasas del año 2018 según la información disponible, con método directo para la tasa regional (9,55 por 100 000 habitantes) e indirecto para las comunas. Las comunas rurales presentaron mayores tasas que las urbanas. Las mujeres mostraron mayor riesgo de intentos (: 1,28; intervalo de confianza 95%: de 1,23 a 1,33) y menor riesgo de suicidio (0,086; de 0,06 a 0,13) que los hombres. Las personas jóvenes presentaron mayor riesgo de intentos y menor riesgo de suicidio, comparado con personas mayores. Destaca el aumento de la tasa de suicidio en personas mayores (de 70 a 79 años) durante el año 2020. El nivel educacional básico es una variable de riesgo para suicidio (2,21; de 1,15 a 4,23), comparado con educación universitaria. Los intentos de suicidio previos y patología psiquiátrica son factores de riesgo. Conclusiones La prevalencia de suicidio y los factores relacionados son similares a lo reportado en otros estudios e informes nacionales, destacando la ruralidad y mayor riesgo en varones de edad adulta avanzada. A diferencia de los suicidios, los intentos son más frecuentes en mujeres y personas jóvenes. Antecedentes de problemas de salud mental, intentos previos y violencia en la familia son factores de riesgo para ambas conductas. Conocer el comportamiento de la conducta suicida en la población es fundamental para su prevención.

Introduction Suicidal behavior is a public health problem worldwide. The World Health Organization estimated 700 000 deaths for the year 2021. Objective This study aimed to estimate the prevalence of suicidal behavior and describe its related factors in the Coquimbo Region, Chile, between 2018 and 2020. Methods 2190 suicide attempt notifications from the regional epidemiological surveillance system were analyzed, corresponding to 1781 people, along with 217 reports from the Forensic Medical Service of people who died by suicide. Results The overall suicide rate for the region during that period was 9.79 deaths per 100 000 inhabitants. The 2018 rates were standardized according to available information, with direct methods for the regional rate (9.55 per 100 000 inhabitants) and indirect methods for the communes. Rural communes presented higher rates than urban ones. Women showed a higher risk of attempts (OR 1.28; 95% CI 1.23 to 1.33) and a lower risk of suicide compared to men (0.086; 0.06 to 0.13). Young people had a higher risk of suicide attempts and a lower risk of suicide compared to older people. The increased suicide rates in older people (70 to 79 years) during 2020 are noteworthy. Basic education level is a risk variable for suicide (2.21; from 1.15 to 4.23), compared to having higher education. Previous suicide attempts and psychiatric pathology are risk factors. Conclusions Suicide prevalence and related factors are similar to those reported in other studies and national reports, highlighting rurality and higher risk in older male adults. In contrast to suicides, attempts are more frequent in women and young people. A history of mental health problems, previous attempts, and family violence are risk factors for both outcomes. Knowing the patterns of suicidal behavior in the population is fundamental for its prevention.

Differential diagnosis of human Entamoeba infections: Morphological and molecular characterization of new isolates in Argentina / Diagnóstico diferencial de infecciones humanas por Entamoeba: caracterización morfológica y molecular de nuevos aislados en Argentina

Abstract Entamoeba infections occur worldwide, with higher frequency in countries of low socioeconomic status and poor public health. Since Entamoeba histolytica has long been recognized as the only pathogenic species, making a differential diagnosis of other morphologically identical Entamoeba is important. This study aimed to determine the prevalence of Entamoeba species in two populations from Argentina, make a differential diagnosis by PCR and characterize Entamoeba isolates at the SSU rRNA gene. A total of 493 serial fecal samples were obtained from individuals in the provinces of Buenos Aires (n=210) and Misiones (n=283). Samples were examined by conventional methods (formalin-ethyl acetate and Willis flotation) and specific PCRs to differentiate Entamoeba species. Entamoeba isolates were characterized by sequencing a fragment of the SSU rRNA gene. The overall prevalence of Entamoeba infection was 12.4%, being more prevalent in Buenos Aires than in Misiones (14.8% vs. 10.6%). A case of E. histolytica confirmed by PCR and sequence analysis was reported for the first time in Buenos Aires. Moreover, new genetic data on Entamoeba coli and Entamoeba dispar were recorded. The phylogenetic analysis revealed a congruence between morphological characteristics and SSU rRNA gene sequences. This study increases the amount of information on the distribution of these species in Argentina and the region of the Americas.

Resumen Las infecciones por Entamoeba se producen en todo el mundo, con mayor frecuencia en países de bajo nivel socioeconómico y salud pública deficiente. Dado que se ha reconocido a Entamoeba histolytica como la única especie patógena del género, es importante realizar un diagnóstico diferencial respecto de otras especies de Entamoeba morfológicamente idénticas. Este estudio tuvo como objetivos determinar la prevalencia de especies de Entamoeba en 2 poblaciones de Argentina, realizar su diagnóstico diferencial por PCR y caracterizar los aislados de Entamoeba secuenciando un fragmento del gen SSU ARNr. Se obtuvieron 493 muestras fecales seriadas de individuos de las provincias de Buenos Aires (n=210) y Misiones (n=283). Las muestras se examinaron por métodos convencionales (sedimentación de formalina-etil acetato y flotación de Willis) y mediante PCR específicas para diferenciar especies de Entamoeba. Los aislamientos de Entamoeba se caracterizaron por secuenciar un fragmento del gen SSU ARNr. La prevalencia general de la infección por Entamoeba fue del 12,4% y fue mayor en Buenos Aires que en Misiones (14,8 vs. 10,6%). Se informó por primera vez un caso de Entamoeba histolytica en Buenos Aires, confirmado por PCR y análisis de secuencia. Además, se registraron nuevos datos genéticos sobre Entamoeba coli y Entamoeba dispar. El análisis filogenético reveló una congruencia entre las características morfológicas y las secuencias del gen SSU ARNr. A través de este estudio, hemos sumado información acerca de la distribución de estas especies en nuestro país y en la región de las Américas.

Noble hosts: effects of internal parasites on the physiology of an intertidal brooding Sea-star / Huéspedes nobles: los efectos de parásitos internos en la fisiología de una estrella de mar incubadora del intermareal

Abstract Introduction: The endoparasite Dendrogaster argentinensis infects the intertidal brooder sea star Anasterias antarctica. This sea-star species is in the highest trophic level in the Beagle Channel. Objective: To study the effects of parasitism by D. argentinensis on the fitness and reproduction of A. antarctica. Methods: Adults from the brooder sea-star were collected from the rocky intertidal of Ensenada Zaratiegui bay (54°51' S & 68°29' W), Argentina. Eight seasonal samplings were performed (four seasons in two years) in the upper and low intertidal. During dissection, parasites were removed, and all organs were extracted and weighed separately. Results: Dendrogaster argentinensis prevalence was the highest for the region (20.4 %). Parasitized individuals were more frequent in the low intertidal in all seasons, with a higher difference in summer, where it is likely that the higher temperatures and strong winds could make the upper intertidal more challenging for a parasitized individual. Five parasitized individuals were castrated. Generally, the gonadal (GI) and somatic (pyloric caeca, PCI; stomach, SI; body wall, WI) indexes were lower in parasitized than non-parasitized individuals. Conclusions: Parasitism by D. argentinensis negatively affects A. antarctica condition. It affects reproduction because it reduces the GI, and can also produce castration. The parasite competes for the sea-stars' energetic resources, also decreasing the individual's capacity for feeding (reduced stomach) and growth (reduced body wall).

Resumen Introducción: El endoparásito Dendrogaster argentinensis infecta a la estrella de mar Anasterias antarctica, especie que se encuentra en el nivel trófico más alto del Canal Beagle. Objetivo: Estudiar los efectos del parasitismo de D. argentinensis en la condición fisiológica y reproducción de A. antarctica. Métodos: Adultos de la estrella de mar incubadora fueron recogidos del intermareal rocoso de la bahía Ensenada Zaratiegui (54°51' S & 68°29' W). Se realizaron ocho muestreos estacionales (cuatro temporadas en dos años) en el intermareal superior y bajo. Durante la disección, se removieron los parásitos, y todos los órganos, los cuales fueron pesados por separado. Resultados: La prevalencia de D. argentinensis fue la más alta de la región (20.4 %). Los individuos parasitados fueron más frecuentes en el intermareal bajo en todas las estaciones, siendo la mayor diferencia en verano, donde es probable que las temperaturas más altas y los fuertes vientos puedan hacer que el intermareal superior sea más desafiante para un individuo parasitado. Se observaron cinco individuos parasitados que estaban castrados. Generalmente, los índices gonadales (GI) y somáticos (ciego pilórico, estómago, y pared del cuerpo) fueron menores en los individuos parasitados que no parasitados. Conclusiones: El parasitismo de D. argentinensis afecta negativamente la condición fisiológica de A. antarctica. Afecta a la reproducción en términos de bajo GI y puede causar castración. El parásito compite por los recursos energéticos de las estrellas de mar, disminuyendo también la capacidad del individuo para alimentarse (reducción del estómago) y crecer (reducción de la pared del cuerpo).

Epidemiología de la apendicitis aguda en Colombia: Un análisis de las bases de datos administrativas del Ministerio de Salud / Epidemiology of acute appendicitis in Colombia: An Analysis of the Ministry of Health administrative databases

Introducción. La apendicitis aguda es una afección común, con un pico de incidencia entre los 10 y 20 años. La cirugía es el tratamiento preferido y la apendicectomía por laparotomía sigue siendo el estándar, aunque el abordaje laparoscópico ha mostrado menos complicaciones. El objetivo de este artículo fue caracterizar tanto la enfermedad como el tratamiento quirúrgico en Colombia, usando datos de bases oficiales. Métodos. Se accedió a la base de datos del Sistema Integrado de Información para la Protección Social (SISPRO) del Ministerio de Salud de Colombia en febrero de 2023. Se recogieron datos de los pacientes con diagnóstico de apendicitis y con procedimiento de apendicectomía entre 2017 y 2021, y se analizaron por edad, sexo y ubicación geográfica. Resultados. Entre 2017 y 2021 se diagnosticaron 345.618 casos de apendicitis (51,8 % mujeres), con pico de incidencia a los 15-20 años. Se realizaron 248.133 apendicectomías, el 16,7 % por laparoscopia. Los hospitales con más procedimientos reportados estaban en Bogotá, Yopal, Popayán y Florencia. La mortalidad fue de 0,56 % en hombres y 0,51 % en mujeres. Conclusión. La apendicitis es común, con pico a los 10-19 años. Las mujeres tienen mayor probabilidad de apendicectomía, debido a otras afecciones ginecológicas. El acceso a la apendicectomía disminuye la mortalidad; en estos pacientes, el 16 % fue laparoscópica, lo que sugiere que se necesita más entrenamiento y acceso a esta técnica. Este estudio aporta a la comprensión de la epidemiología de la apendicitis y apendicectomías en Colombia.

Introduction. Acute appendicitis is a common condition, with a peak incidence between 10 and 20 years of age. Surgery is the preferred treatment and laparotomy appendectomy remains the standard, although the laparoscopic approach has shown fewer complications. The objective of this article was to characterize both the disease and the surgical treatment in Colombia, using data from official databases. Methods. The Integrated Information System for Social Protection (SISPRO) database of the Ministry of Health was accessed in February 2023. Data with diagnosis of apendicitis and with appendectomy between 2017 and 2021 were collected. Analysis was done by age, gender, and geographic location. Results. Between 2017 and 2021, 345,618 cases of appendicitis were diagnosed (51.8% females), with peak incidence at 15-20 years of age. A total of 248,133 appendectomies were performed, 16.7% by laparoscopy. The hospitals with most reported procedures were located in Bogotá, Yopal, Popayán, and Florencia. Mortality was 0.56% in men and 0.51% in women. Conclusion. Appendicitis is common, peaking at ages 10-19. Women are more likely undergo appendectomy due to other gynecological conditions. Access to appendectomy improves mortality. In these patients, 16% were laparoscopic, suggesting that more training and access to this technique is needed. This study contributes to the understanding of the epidemiology of appendicitis and appendectomies in Colombia.

Cáncer incidental de vesícula: incidencia y factores asociados en pacientes de una institución de la ciudad de Medellín / Incidental gallbladder cancer: Incidence and associated factors in patients from an institution in the city of Medellín

Introducción. El cáncer de vesícula biliar es una de las neoplasias más frecuentes de la vía biliar y la mayoría de los casos se diagnostican de forma incidental o en estadios avanzados. En Colombia existen pocas publicaciones acerca de la prevalencia y características clínicas de pacientes con cáncer insospechado de vesícula biliar. El objetivo de este trabajo fue actualizar la información existente. Métodos. Estudio de tipo transversal basado en registros médicos. Como variable de resultado se definió el hallazgo incidental de patología maligna reportado por un patólogo y el subtipo histológico. Se midieron variables demográficas, clínicas y quirúrgicas. Se calcularon OR con sus respectivos intervalos de confianza (IC95%). Resultados. De los 2630 casos analizados, en cuatro se hizo diagnóstico de cáncer incidental de vesícula, con una prevalencia del 0,15 %. Se encontraron como características asociadas al cáncer incidental de vesícula, la edad, el antecedente de cáncer y la presencia de pólipos. Conclusiones. Esta es una patología poco frecuente en la población evaluada, lo que permite afirmar que no es necesario realizar estudios prequirúrgicos más amplios de forma rutinaria, a menos que el paciente presente alguno de los factores asociados.

Introduction. Gallbladder cancer is one of the most common neoplasms of the bile duct and most cases are diagnosed incidentally or in advanced stages. In Colombia, there are few publications about the prevalence and clinical characteristics of patients with unsuspected gallbladder cancer. The objective of this work was to update the existing information. Methods. Cross-sectional study based on medical records. The incidental finding of malignant pathology reported and the histological subtype were defined as the outcome variable. Demographic, clinical and surgical variables were measured. ORs were calculated with their respective 95% CI. Results. Of the 2630 cases analyzed, four were diagnosed with incidental gallbladder cancer, with a prevalence of 0.15%. Characteristics associated with incidental gallbladder cancer were age, history of cancer and the presence of polyps. Conclusions. This is a rare pathology in the population evaluated, which allows us to recommend that it is not necessary to routinely perform more extensive presurgical studies, unless the patient presents any of the associated factors.

Prevalence and risk factors for falls among older Chinese adults in the community: findings from the CLHLS study

Older adults have a high prevalence of falls due to a decline in physiological functions and various chronic diseases. This study aimed to investigate the prevalence of and risk factors for falls among older individuals in the Chinese Longitudinal Healthy Longevity Survey (CLHLS). We collected information from 9737 older individuals (average age=84.26 years) from the CLHLS and used binary logistic regression analysis to explore the independent risk factors and protective factors for falls. The logistic regression analysis results are reported as adjusted odds ratios (aORs) and 95% confidence intervals (95%CIs). The prevalence of falls among older adults in China was 21.6%, with women (24.6%) having a higher prevalence than men (18.1%). Logistic regression analysis revealed that never (or rarely) eating fresh fruit, difficulty with hearing, cataracts, and arthritis were the common independent risk factors for falls in older Chinese men and women. Among men, age ≥80 years (aOR=1.86), never doing housework (aOR=1.36), and dyslipidemia (aOR=1.47) were risk factors, while eating milk products once a week was a protective factor. Alcohol consumption (aOR=1.40), physical labor (aOR=1.28), and heart disease (aOR=1.21) were risk factors for falls in women, while a daily sleep duration of 6-12 h and garlic consumption once a week were protective factors. The prevalence of falls among older adults in China is 21.6% and is greater in women than in men. These risk and protective factors can be used to formulate reasonable recommendations for living habits, diet, and chronic disease control strategies.

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.

Prevalência de anomalias dentárias e outros achados orais em radiografias panorâmicas de brasileiros com fissura labiopalatal: um estudo retrospectivo / Prevalence of dental anomalies and other oral findings on panoramic radiographs of Brazilian with cleft lip and palate: a retrospective study

Objetivo: avaliar a prevalência de anomalias dentárias (AD) e outros achados orais em radiografias panorâmicas de pacientes com fissuras labiopalatais (FLP) nascidos no Nordeste brasileiro. Métodos: a amostra foi composta por 69 pacientes com fissuras labiopalatais unilateral (FLPu) (n = 51) e bilateral (FLPb) (n = 18), não sindrômicos, de ambos os sexos, idade de 6 a 17 anos, nascidos no Nordeste brasileiro. Foram analisados prontuários e radiografias panorâmicas de pacientes atendidos de janeiro/2020 a julho/2022. Os dados categóricos foram expressos em forma de frequência absoluta e percentual e comparados por teste exato de Fisher ou qui-quadrado de Pearson (SPSS, p < 0,05). Resultados: entre os achados orais, destacaram-se as anomalias de número e as ausências dentárias por trauma, cárie ou doença periodontal. As AD foram identificadas em 34 pacientes (49,3%). As anomalias de número apresentaram maior prevalência, com diferença estatística significativa para pacientes FLPb do sexo masculino (p = 0,047). A agenesia foi a AD mais frequente (n = 24; 34,8%). As ausências dentárias por trauma, cárie ou doença periodontal foram observadas em 44 pacientes (n = 63,8%), com uma diferença estatística significativa entre os grupos FLPu e FLPb (p = 0,018). Conclusões: as AD e as ausências dentárias por trauma, cárie ou doença periodontal apresentaram uma alta prevalência entre pacientes brasileiros com FLP e devem ser consideradas durante o planejamento ortodôntico-cirúrgico desses indivíduos.

Aim: this study aimed to assess the prevalence of dental anomalies (DA) and other oral findings in panoramic radiographs of patients with cleft lip and palate (CLP) born in the Northeast region of Brazil. Methods: the sample consisted of 69 patients with unilateral cleft lip and palate (UCLP) (n = 51) and bilateral cleft lip and palate (BCLP) (n = 18), non-syndromic, of both genders, aged 6 to 17 years, born in the Brazilian Northeast. Patient records and panoramic radiographs from those treated between January 2020 and July 2022 were analyzed. Categorical data were expressed as absolute frequency and percentage and compared using Fisher's exact test or Pearson's chi-square test (SPSS, p < 0.05). Results: among oral findings, anomalies in number and tooth absences due to trauma, caries, or periodontal disease stood out. DAs were identified in 34 patients (49.3%). Anomalies in number showed higher prevalence, with a statistically significant difference for male BCLP patients (p = 0.047). Agenesis was the most frequent DA (n = 24; 34.8%). Tooth absences due to trauma, caries, or periodontal disease were observed in 44 patients (63.8%), with a statistically significant difference between the UCLP and BCLP groups (p = 0.018). Conclusions: DAs and tooth absences due to trauma, caries, or periodontal disease showed a high prevalence among Brazilian patients with CLP and should be considered during the orthodontic-surgical planning for these individuals.

Efecto del confinamiento por COVID-19 en la prevalencia de la enfermedad hepática esteatósica asociada a disfunción metabólica / Effect of COVID-19 lockdown on the prevalence of metabolic dysfunction-associated steatotic liver disease

Introducción. La enfermedad hepática esteatósica asociada a disfunción metabólica (MASLD) es una condición clínica frecuente, relacionada con el sobrepeso, la dislipidemia y la diabetes. Como estos factores de riesgo están a su vez asociados al sedentarismo y la ganancia de peso, se esperaría un impacto como resultado del confinamiento por COVID-19 en la prevalencia de dicha condición. Metodología. Estudio longitudinal retrospectivo en un panel de datos de 132 pacientes de 2017 a 2022, en donde fueron incluidos pacientes con una ecografía hepática y una valoración médica y paraclínica 1,5 años antes y después del periodo de confinamiento (25 de marzo de 2020 a 28 de febrero de 2021). El desenlace primario fue un cambio significativo en la prevalencia de la MASLD, y se utilizó un modelo exploratorio de regresión logística de efectos fijos con panel de datos para hallar los predictores de cambio. Resultados. En un total de 132 pacientes analizados, la prevalencia global de la MASLD antes (31 %; IC95%: 23-39) y después (35,6 %; IC95%: 27,4-43,8) del confinamiento por COVID-19 no cambió significativamente, sin embargo, en las mujeres sí hubo un aumento significativo (RR: 4; IC95%: 1,0004-16). Se encontró una marcada diferencia de prevalencia entre sexos (17 % en mujeres y 46 % en hombres; p=0,001). El confinamiento se asoció a incrementos en la masa corporal (diferencia: +1 kg; IC95%: 0,1-1,9), el colesterol LDL (diferencia: +9,7 mg/dL; IC95%: 4,9-14,4) y al diagnóstico de prediabetes (RR: 2,1; IC95%: 1,4-3,1). La MASLD se asoció positivamente a la preferencia nutricional por la comida rápida (p=0,047). Solo el índice de masa corporal resultó predictor independiente de MASLD (RR: 1,49; IC95%: 1,07-1,93). Conclusión. La prevalencia global de la MASLD no varió después del confinamiento por COVID-19, pero sí se incrementó en mujeres, y algunos de sus factores de riesgo también aumentaron significativamente. Se encontró equivalencia numérica entre la MASLD y la definición previa de la enfermedad. Se requiere un estudio local más grande para desarrollar y validar un mejor modelo predictor del cambio de la MASLD a través del tiempo.

Introduction. Metabolic dysfunction-associated steatotic liver disease (MASLD) is a common clinical condition, related to overweight, dyslipidemia and diabetes. As these risk factors are in turn associated with sedentary lifestyle and weight gain, an impact as a result of the COVID-19 confinement on the prevalence of MASLD would be expected. Methodology. Retrospective longitudinal study in a data panel of 132 patients from 2017 to 2022. Patients with a liver ultrasound and a medical and paraclinical assessment 1.5 years before and after the confinement period (March 25, 2020 to February 28, 2021) were included. The primary outcome was a significant change in the prevalence of MASLD, and an exploratory fixed-effects logistic regression model with panel data was used to find predictors of change. Results. In a total of 132 patients analyzed, the overall prevalence of MASLD before (31%, 95%CI: 23-39) and after (35.6%, 95%CI: 27.4-43.8) confinement by COVID-19 did not change significantly, however, in women there was a significant increase (RR: 4, 95%CI: 1.0004-16). A marked difference in prevalence was found between sexes (17% in women and 46% in men; p=0.001). Confinement was associated with increases in body mass (difference: +1 kg, 95%CI: 0.1-1.9), LDL cholesterol (difference: +9.7 mg/dL, 95%CI: 4.9-14.4) and the diagnosis of prediabetes (RR: 2.1, 95%CI: 1.4-3.1). MASLD was positively associated with nutritional preference for fast food (p=0.047). Only body mass index was an independent predictor of MASLD (RR: 1.49, 95%CI: 1.07-1.93). Conclusion. The overall prevalence of MASLD did not change after the COVID-19 lockdown, but it did increase in women, and some of its risk factors also increased significantly. Numerical equivalence was found between MASLD and the previous definition of the disease. A larger local study is required to develop and validate a better predictor model of MASLD change over time.

Prevalencia y características genotípicas de la infección anal por papilomavirus en una cohorte de hombres que tienen sexo con hombres VIH-positivos / Prevalence and genotypic characteristics of anal papillomavirus infection in a cohort of HIV-positive men who have sex with men

RESUMEN Objetivo: Determinar la prevalencia y las características genotípicas de la infección anal por papilomavirus en hombres que tienen sexo con hombres (HSH) VIH-positivos. Materiales y métodos: Es un estudio observacional prospectivo de corte transversal en HSH VIH-positivos del Hospital Nacional Guillermo Almenara Irigoyen, EsSalud, realizado entre setiembre del 2017 y diciembre del 2018. El estudio del papilomavirus se realizó con una técnica de reacción en cadena de polimerasa evaluando 21 genotipos estratificados según el riesgo oncogénico: seis de bajo riesgo y quince de alto riesgo. Resultados: Se evaluaron 214 HSH VIH-positivos. La prevalencia general de la infección anal por papilomavirus fue de 70% (150/214). 86% (129/150) tuvieron genotipos de alto riesgo oncogénico, de ellos 79% (102/129) tuvieron dos o más genotipos de papilomavirus. Los genotipos de alto riesgo oncogénico más frecuentes fueron: VPH-16, 31% (46/150); VPH-52, 22% (33/150); VPH-33, 21% (31/150); VPH-58, 21% (31/150) y VPH-31, 20% (30/150). El VPH-18 alcanzó el 7% (10/150). Los genotipos de bajo riesgo oncogénico más frecuentes fueron: VPH-6, 30% (45/150) y VPH-11, 29% (44/150). Conclusiones: La prevalencia de la infección anal por papilomavirus en HSH VIH-positivos es muy alta en el hospital investigado. La gran mayoría de estas infecciones se producen con genotipos de alto riesgo oncogénico. El papilomavirus 16 fue el genotipo de alto riesgo más frecuente.

ABSTRACT Objective: To determine the prevalence and genotypic characteristics of anal papillomaviruses in HIV-positive men who have sex with men (MSM). Materials and methods: This is a prospective cross-sectional observational study of HIV-positive MSM at Almenara General Hospital between September 2017 and December 2018. HPV detection and typing was performed using a polymerase chain reaction technique that evaluated 21 genotypes stratified according to oncogenic risk into six low-risk and fifteen high-risk. Results: we evaluated 214 HIV-positive MSM. The overall prevalence of anal infection by papillomavirus infection was 70% (150/214). 86% (129/150) were caused by high-risk genotypes, 79% (102/129) of them were affected by a two or more-papillomavirus genotype. The most frequent high-risk genotypes were HPV-16, 31% (46/150); HPV-52, 22% (33/150); HPV-33, 21% (31/150); HPV-58, 21% (31/150) and HPV-31, 20% (30/150). In addition, HPV-18 reached 7% (10/150). The most frequent low-risk genotypes were HPV-6, 30% (45/150) and HPV 11, 29% (44/150). Conclusions: Prevalence of anal papillomavirus infection in HIV-positive MSM is very high in the hospital investigated. Most of these infections occurs with high-risk oncogenic genotypes. Papillomavirus 16 was the most frequent high-risk genotype.

Trends and age-period-cohort effect on dental caries prevalence from 2008 to 2019 among Brazilian preschoolers

Abstract This study aimed to evaluate trends in the prevalence of dental caries in preschool children and associated factors considering different time variations. This is a time series study performed using data from three cross-sectional studies with pre-school children from southern Brazil in 2008, 2013 and 2019. This children group was born between the years of 2003 to 2018. Dental caries was evaluated by decayed, missing and filled deciduous teeth (dmft index). Demographic, socioeconomic, behavioural and psychosocial variables were also collected. Chi-square test for trends and a hierarchical age-period-cohort (HAPC) analysis using multilevel Poisson regression model for testing the associations between predictor variables and dental caries experience were used. A total of 1,644 pre-school children participated in all surveys. There was a significant difference in caries experience considering all APC effects. The prevalence of dental caries was 25.0% in 2008, 16.3% in 2013, and 19.4% in 2019 (p < 0.01) and no statistical difference was observed. An age effect showed that older children were more likely to experience dental caries. Considering the cohort effect, there is a significant difference between the generations, mainly between 2003 and 2018. Household income, use of dental services, and parent's perception of child oral health were associated with dental caries experience no matter the time variation. Despite recent declines in dental caries prevalence among preschool children, caries levels increased with age and social inequalities persisted through the years, indicating a need of reviewing the policies to reduce the burden of this oral disease.

Is resistance training a protective factor for musculoskeletal injuries in crossfit practitioners? / ¿es el entrenamiento de resistencia un factor protector de las lesiones musculoesqueléticas en crossfit? / Treinamento resistido é um fator de proteção para lesões musculoesqueléticas no crossfit?

ABSTRACT Objective: To evaluate the prevalence and characteristics of musculoskeletal injuries associated with CrossFit® practitioners and the relationship of this prevalence among those who concomitantly perform resistance training (RT). Methods: Cross-sectional study in which adult participants of both sexes were included, who answered a mixed morbidity questionnaire adapted. The participants were allocated into groups according to whether or not they practiced another modality along with CrossFit®, with emphasis on RT. Analytical and descriptive statistics procedures were used, with a statistical significance level of 5% (p<0.05). Results: A total of 179 participants were included in the study. Prevalences of musculoskeletal injuries were observed in the overall study sample of 32.4% and in those who perform CrossFit® with RT of 30.8%. The injury prevalence ratio for this group was 0.95, with lower injury prevalence for the upper limbs (p=0.03) and lower limbs (p=0.02). It is worth noting that 96% of the CrossFit® and RT practitioners did strength training focused only on the upper and/or lower limb musculatures, without specific training for the anatomical segment of the Core (lumbar and pelvis). Conclusion: RT associated with CrossFit® and covering all anatomical segments, can be considered a protective factor for the occurrence of musculoskeletal injuries in CrossFit®. Level of Evidence IV; Case Series.

RESUMEN Objetivo: Evaluar la prevalencia y las características de las lesiones musculoesqueléticas asociadas a los practicantes de CrossFit® y la relación entre esta prevalencia y los que realizan simultáneamente entrenamiento de resistencia (ER). Métodos: Se trató de un estudio transversal en el que participaron adultos de ambos sexos que respondieron a un cuestionario adaptado de morbilidad mixta. Los participantes se dividieron en grupos según practicaran o no otro deporte junto con CrossFit®, en particular entrenamiento de resistencia. Se utilizaron procedimientos estadísticos analíticos y descriptivos, con un nivel de significación estadística del 5% (p<0,05). Resultados: Se incluyó en el estudio a un total de 179 participantes. Hubo una prevalencia de lesiones musculoesqueléticas en la muestra global del estudio del 32,4% y en los que practicaban CrossFit® con ER del 30,8%.El ratio de prevalencia de lesiones para este grupo fue de 0,95, con una menor prevalencia de lesiones en las extremidades superiores (p=0,03) y en las extremidades inferiores (p=0,02).Cabe destacar que el 96% de los practicantes de CrossFit® y ER realizaban entrenamientos de fuerza centrados únicamente en la musculatura de los miembros superiores y/o inferiores, sin realizar entrenamientos específicos para el segmento anatómico del Core (regiones lumbar y pélvica). Conclusión: El ER asociado al CrossFit® y que cubre todos los segmentos anatómicos puede ser considerado un factor protector contra la ocurrencia de lesiones músculo-esqueléticas en CrossFit®. Nivel de Evidencia IV; Serie de Casos.

Conclusão: O TR associado ao CrossFit® e com abrangência a todos os segmentos anatômicos pode ser considerado um fator de proteção para a ocorrência de lesões musculoesquelética no CrossFit®. Nível de Evidência IV; Série de Casos.

Prevalence, trends, and factors associated with hypertensive crisis among Peruvian adults / Prevalencia, tendencias y factores asociados a la crisis hipertensiva en adultos peruanos / Prevalência, tendências e fatores associados à crise hipertensiva em adultos peruanos

There are few studies focused on the epidemiology of hypertensive crisis at the population level in resource-constrained settings. This study aimed to determine the prevalence and trends over time of hypertensive crisis, as well as the factors associated with this condition among adults. A secondary data analysis was carried out using the Peruvian Demographic and Family Health Survey (ENDES). Hypertensive crisis was defined based on the presence of systolic (≥ 180mmHg) or diastolic (≥ 110mmHg) blood pressure, regardless of previous diagnosis or medication use. The factors associated with our outcome were evaluated using multinomial logistic regression, and the trend of hypertensive crisis was evaluated using the Cochrane-Armitage test. Data from 260,167 participants were analyzed, with a mean age of 44.2 (SD: 16.9) years and 55.5% were women. Hypertension prevalence was 23% (95%CI: 22.7-23.4) and, among them, 5.7% (95%CI: 5.4-5.9) had hypertensive crisis, with an overall prevalence of 1.5% (95%CI: 1.4-1.6). From 2014 to 2022, a significant decrease in the prevalence of hypertensive crisis was observed, from 1.7% in 2014 to 1.4% in 2022 (p = 0.001). In the multivariable model, males, increasing age, living in urban areas, high body mass index, and self-reported type 2 diabetes were positively associated with hypertensive crisis, whereas higher educational level, socioeconomic status, and high altitude were inversely associated. There is a need to improve strategies for the diagnosis, treatment, and control of hypertension, especially hypertensive crisis.

Pocos estudios se han centrado en la epidemiología de la crisis hipertensiva a nivel poblacional en entornos de recursos limitados. El objetivo de este estudio fue determinar la prevalencia y tendencia, a lo largo del tiempo, de la crisis hipertensiva y los factores asociados a esta condición en adultos. Se realizó un análisis de datos secundarios utilizando la Encuesta Demográfica de Salud Familiar (ENDES) de Perú. La crisis hipertensiva se definió en función de la presencia de presión arterial sistólica (≥ 180mmHg) o diastólica (≥ 110mmHg), independientemente del diagnóstico previo o del uso de medicamentos. Los factores asociados a los resultados se evaluaron mediante regresión logística multinomial, y la tendencia a la crisis hipertensiva se estimó mediante la prueba Cochran-Armitage. Los datos de 260.167 participantes, con una media de 44,2 años (DE: 16,9) y 55,5% mujeres, fueron analizados. La prevalencia de hipertensión fue del 23% (IC95%: 22,7-23,4), de la cual el 5,7% (IC95%: 5,4-5,9) tuvo crisis hipertensiva, con una prevalencia general del 1,5% (IC95%: 1,4-1,6). En el período 2014-2022 se constató una disminución significativa en la prevalencia de crisis hipertensiva, del 1,7% en 2014 al 1,4% en 2022 (p = 0,001). En el modelo multivariable, el sexo masculino, el aumento de la edad, vivir en áreas urbanas, el alto índice de masa corporal y la diabetes autoinformada se asociaron positivamente con la crisis hipertensiva, mientras que mayor nivel educativo, nivel socioeconómico y elevada altitud estuvieron asociadas de manera inversa. Es necesario mejorar las estrategias para el diagnóstico, el tratamiento y el control de la hipertensión, especialmente de la crisis hipertensiva.

Uma análise de dados secundários foi realizada usando a Pesquisa Demográfica de Saúde Familiar (ENDES) do Peru. Crise hipertensiva foi definida com base na presença de pressão arterial sistólica (≥ 180mmHg) ou diastólica (≥ 110mmHg), independentemente de diagnóstico prévio ou uso de medicação. Os fatores associados aos resultados foram avaliados por meio de regressão logística multinomial, e a tendência de crise hipertensiva foi avaliada pelo teste de Cochrane-Armitage. Os dados de 260.167 participantes, com média de 44,2 anos (DP: 16,9) e 55,5% mulheres, foram analisados. A prevalência de hipertensão foi de 23% (IC95%: 22,7-23,4), dentre eles, 5,7% (IC95%: 5,4-5,9) apresentaram crise hipertensiva, com prevalência geral de 1,5% (IC95%: 1,4-1,6). De 2014 a 2022, observou-se queda significativa na prevalência de crise hipertensiva, de 1,7% em 2014 para 1,4% em 2022 (p = 0,001). No modelo multivariável, sexo masculino, idade crescente, residir em área urbana, índice de massa corporal elevado e diabetes autorreferido associaram-se positivamente à crise hipertensiva, enquanto maior escolaridade, nível socioeconômico e altitude elevada associaram-se inversamente. Há necessidade de aprimorar as estratégias de diagnóstico, tratamento e controle da hipertensão arterial, especialmente da crise hipertensiva.

Racial and ethnic disparities in premature births among pregnant women in the NISAMI cohort, Brazil / Disparidades étnicas e raciais nos partos prematuros entre gestantes da coorte NISAMI, Brasil

Abstract The incidence of premature birth has increased worldwide, unequally distributed by race/ethnicity. Racism generates economic inequalities, educational disparities, and differential access to health care, which increases the risk of preterm birth. Thus, this study aimed to evaluate the factors associated with preterm birth and racial and ethnic disparities in premature birth among pregnant women attending prenatal care at the Brazilian Unified Health System health units in the urban area of Santo Antônio de Jesus, Bahia, Brazil. This study used data from 938 pregnant women aged between 18 to 45 years within the NISAMI prospective cohort. Premature birth prevalence was 11.8%, with a higher prevalence among black than non-black women (12.9% versus 6.0%, respectively). Maternal age between 18 and 24 years was the only factor associated with premature birth. A higher risk of premature birth was found among black women than non-black women (RR 3.22; 95%CI 1.42-7.32). These results reveal the existence of racial and social inequalities in the occurrence of premature birth.

Resumo A incidência de parto prematuro tem aumentado em todo o mundo, distribuída de forma desigual por raça/etnia. O racismo gera desigualdades econômicas, disparidades educacionais e acesso diferenciado à saúde, o que aumenta o risco de parto prematuro. Assim, este estudo teve como objetivo avaliar os fatores associados à prematuridade e disparidades raciais e étnicas no parto prematuro entre gestantes atendidas durante o pré-natal em unidades de saúde do Sistema Único de Saúde na zona urbana de Santo Antônio de Jesus, Bahia, Brasil. Este estudo utilizou dados de 938 mulheres grávidas com idade entre 18 e 45 anos dentro da coorte prospectiva do NISAMI. A prevalência de prematuridade foi de 11,8%, sendo maior entre as negras do que entre as não negras (12,9% versus 6,0%, respectivamente). A idade materna entre 18 e 24 anos foi o único fator associado ao parto prematuro. Foi encontrado maior risco de prematuridade entre as mulheres negras do que entre as não negras (RR 3,22; IC95% 1,42-7,32). Esses resultados revelam a existência de desigualdades raciais e sociais na ocorrência do parto prematuro.

Prevalence and clinical consequences of Hepatitis C virus infection in patients undergoing hematopoietic stem cell transplantation

ABSTRACT Hepatitis C virus (HCV) infection is a significant cause of morbidity and mortality among hematopoietic stem cell transplant (HCT) recipients. In Brazil, its occurrence in HCT recipients remains undetermined. We now report on HCV prevalence in HCT recipients and its clinical consequences. The medical records of all HCT recipients seen at Hospital das Clinicas, Sao Paulo University Medical School, from January 2010 to January 2020 were reviewed to determine HCV serostatus. A retrospective analysis of medical charts was undertaken on all seropositive cases to determine HCV genotype, presence of liver fibrosis, co-infections with other viruses, previous treatments, and clinical evolution of liver pathology after HCT. Of the 1,293 HCT recipients included in the study, seven (0.54%) were HCV antibody-positive and five (0.39%) were also viremic for HCV-RNA. Four of these individuals had moderate to severe liver fibrosis (METAVIR F2/F3) and one was cirrhotic. Two of the viremic patients developed acute liver dysfunction following transplantation. All patients had their acute episode of liver dysfunction resolved with no further complications. Four of the viremic patients were treated for HCV infection with direct acting agents (DAA). Information regarding HCV treatment was lacking for one of the viremic HCV patients due to loss of follow up. Sustained anti-virologic responses were observed in three cases after the use of DAA. The detection of HCV in hematological adults undergoing HCT and its successful treatment with DAA highlight the necessity of testing for HCV both prior to and following transplantation.

Factors Associated with Hyposalivation in Brazilian Adults

ABSTRACT Objective: To determine the occurrence of hyposalivation in Brazilian adults and its association with individual determinants, such as the use of medications, systemic conditions, smoking, and alcohol consumption. Material and Methods: A cross-sectional study with 402 adults was developed. Information was collected on sociodemographic and general health characteristics, and sialometry was performed with stimulated salivary flow. It indicated low salivary flow when ≤ 0.7 mL/min. Bivariate and multivariate analyses were conducted using a decision tree (p<0.05). Results: The sample was comprised predominantly of women (68.2%) aged ≤ 29 years (25.4%). Most participants did not use medication (56.7%). Among systemic diseases, the most cited was hypertension (25.1%). More than a third of the participants presented hyposalivation (40.3%), being associated with the following variables: age between 50 to 59 years (p=0.011), female sex (p<0.001), menopause (p=0.001), use of alcohol (p=0.033), systemic disease (p=0.002) and medication use (p<0.001). In multivariate analysis, in addition to sex (p<0.001) and hypertension (p=0.005), an association was also found between hyposalivation and diabetes (p=0.014). Conclusion: Factors associated with hyposalivation in adults were sex and the presence of hypertension or diabetes.

Introdução: analisar a prevalência e os fatores associados à doença renal crônica em pessoas com hipertensão arterial (HAS) cadastrados na Estratégia de Saúde da Família em Rio Branco, Acre. Método: Trata-se de um estudo transversal realizado com hipertensos cadastrados nas Estratégias de Saúde da Família (ESF), na zona urbana de Rio Branco, Acre, em 2019. A DRC foi definida por TFG < 60 ml/1,72m², estimada a partir da fórmula Chronic Kidney Disease Epidemiology Collaboration (CKD-EPI), ou presença de albuminúria > 29 mg/g. Medidas de associação foram estimadas por regressão logística, com grau de confiança de 95%. Resultados: A prevalência de DRC foi de 27,3% em pessoas com HAS. Observou-se associação estatisticamente significativa nos pacientes hipertensos entre DRC e escolaridade (ensino fundamental ­ OR: 1,56; IC95%:1,09; 2,23; sem escolaridade ­ OR:1,87; IC95%: 1,14; 3,07), não controle da pressão arterial (OR: 2,39; IC95%: 1,45; 3,94), sedentarismo (OR: 1,63; IC95%: 1,02; 2,60). Conclusão: A DRC apresenta alta prevalência nos hipertensos, evidenciando a necessidade de medidas em saúde pública para prevenção de complicações mediante melhor controle da doença e mudanças no estilo de vida.

Introduction: To analyze the prevalence and factors associated with chronic kidney disease in people with hypertension (SAH) registered in the Family Health Strategy in Rio Branco, Acre. Method: This is a cross-sectional study carried out with hypertensive patients registered in the Family Health Strategies (ESF), in the urban area of Rio Branco, Acre, in 2019. CKD was defined by GFR < 60 ml/1.72m², estimated from the Chronic Kidney Disease Epidemiology Collaboration (CKD-EPI) formula, or presence of albuminuria > 29 mg/g. Association measures were estimated using logistic regression, with a 95% confidence level. Results: The prevalence of CKD was 27.3% in people with hypertension. A statistically significant association was observed in hypertensive patients between CKD and education (primary education ­ OR: 1.56; 95% CI: 1.09; 2.23; no education ­ OR: 1.87; 95% CI: 1.14; 3.07), lack of blood pressure control (OR: 2.39; 95% CI: 1.45; 3.94), sedentary lifestyle (OR: 1.63; 95% CI: 1.02; 2.60). Conclusion: CKD has a high prevalence in hypertensive patients, highlighting the need for public health measures to prevent complications through better control of the disease and changes in lifestyle.

Introducción: Se analizó la prevalencia y los factores asociados a la enfermedad renal crónica (ERC) en personas con hipertensión arterial (HTA) inscritas en la Estrategia de Salud Familiar en Rio Branco, Acre. Método: Estudio transversal con hipertensos inscritos en las Estrategias de Salud Familiar (ESF) en la zona urbana de Rio Branco, Acre, en 2019. La ERC se definió por un FG <60 ml/1,72m², estimado a partir de la fórmula de Colaboración de Epidemiología de Enfermedades Renales Crónicas (CKD-EPI), o la presencia de albuminuria >29 mg/g. Se estimaron medidas de asociación mediante regresión logística, con un nivel de confianza del 95%. Resultados: La prevalencia de ERC fue del 27,3% en personas con HTA. Se observó una asociación estadísticamente significativa entre la ERC y la escolaridad (educación primaria ­ OR: 1,56; IC95%: 1,09; 2,23; sin escolaridad ­ OR: 1,87; IC95%: 1,14; 3,07), falta de control de la presión arterial (OR: 2,39; IC95%: 1,45; 3,94), y sedentarismo (OR: 1,63; IC95%: 1,02; 2,60) en pacientes hipertensos. Conclusión: La ERC presenta una alta prevalencia en pacientes hipertensos, lo que destaca la necesidad de medidas de salud pública para prevenir complicaciones mediante un mejor control de la enfermedad y cambios en el estilo de vida.
