Assistência pré-natal às usuárias de substâncias psicoativas: dificuldades elencadas pelos profissionais da saúde / Prenatal care for users of psychoactive substances: difficulties listed by health professionals / Atención prenatal a consumidoras de sustancias psicoactivas: dificultades mencionadas por los profesionales de la salud

Objetivo: conhecer as dificuldades elencadas pelos profissionais de saúde na assistência pré-natal às usuárias de substâncias psicoativas. Método: estudo qualitativo, exploratório-descritivo, realizado nas mídias sociais, com profissionais da área da saúde que realizam atendimento pré-natal. A coleta de dados ocorreu de novembro de 2022 a janeiro de 2023 por meio de questionário eletrônico. Os dados foram analisados por meio da análise temática. Protocolo aprovado pelo Comitê de Ética em Pesquisa. Resultados: os profissionais destacam o déficit de conhecimento para abordar este público em específico. A abordagem superficial e condenatória do uso de substâncias pelas políticas públicas corrobora para que os profissionais se sintam preparados em parte para atender essas gestantes. Considerações finais: a capacitação dos profissionais é necessária para superar práticas condenatórias e retrógradas de cuidado que focam unicamente a abstinência; como também, o investimento na capacitação acerca da rede de atenção à saúde, buscando ampliar sua visibilidade e utilização.

Objective: understanding the difficulties listed by health professionals in prenatal care for users of psychoactive substances. Method: this is a qualitative, exploratory-descriptive study carried out on social media with health professionals who provide prenatal care. Data was collected from November 2022 to January 2023 using an electronic questionnaire. The data was analyzed using thematic analysis. Protocol approved by the Research Ethics Committee. Results: the professionals highlight the lack of knowledge to deal with this specific public. The superficial and condemnatory approach to substance use by public policies contributes to making professionals feel partly prepared to deal with these pregnant women. Final considerations: the training of professionals is necessary to overcome condemnatory and retrograde care practices that focus solely on abstinence; and investment in training about the health care network, seeking to increase its visibility and use.

Exploring the potential of omics technologies in medicinal plant research: a review in Colombia / Explorando el potencial de las tecnologías ómicas en la investigación de plantas medicinales: una revisión en Colombia

This review presents advances in the implementation of high - throughput se quencing and its application to the knowledge of medicinal plants. We conducted a bibliographic search of papers published in PubMed, Science Direct, Google Scholar, Scopus, and Web of Science databases and analyzed the obtained data using VOSviewer (versi on 1.6.19). Given that medicinal plants are a source of specialized metabolites with immense therapeutic values and important pharmacological properties, plant researchers around the world have turned their attention toward them and have begun to examine t hem widely. Recent advances in sequencing technologies have reduced cost and time demands and accelerated medicinal plant research. Such research leverages full genome sequencing, as well as RNA (ribonucleic acid) sequencing and the analysis of the transcr iptome, to identify molecular markers of species and functional genes that control key biological traits, as well as to understand the biosynthetic pathways of bioactive metabolites and regulatory mechanisms of environmental responses. As such, the omics ( e.g., transcriptomics, metabolomics, proteomics, and genomics, among others) have been widely applied within the study of medicinal plants, although their usage in Colombia is still few and, in some areas, scarce.

Sentimentos da mulher frente a gestação de alto risco / Sentimientos de la mujer frente al embarazo de alto riesgo / Women's feelings facing High-Risk pregnancy

Resumo Introdução: A gestação configura-se como um acontecimento único e memorável para a vida de uma mulher. A gravidez de alto risco é uma experiência estressante em razão dos riscos a que estão submetidos a mãe e o bebê e devido às mudanças que afetam negativamente o seu equilíbrio emocional. Objetivo: Identificar os sentimentos vivenciados pela gestante frente à gravidez de alto risco. Método: Descritivo e exploratório com abordagem qualitativa, com amostra por conveniência composta por mulheres com gestação de alto risco, selecionadas de acordo com a disponibilidade do serviço de internamento, até a saturação das entrevistas. A coleta dos dados foi realizada em um período de dois meses através de entrevistas guiadas por um roteiro. Os dados foram analisados por meio da técnica de análise de conteúdo segundo Minayo. Resultados: Fizeram parte 37 mulheres. Os resultados foram oeganizados nas categorias: Como se deu o diagnóstico de alto risco; Sentimentos ao descobrir que a gestação é/era de risco; Sentimentos em relação ao apoio familiar acerca da gestação de alto risco. Os sentimentos relatados pelas gestantes e puérperas que conviveram com a gravidez de alto risco, deixam evidentes os impactos que este evento traz não somente na saúde física sobretudo para a emocional, deixando as gestantes fragilizadas. Conclusão: Assim, o estudo nos permitiu perceber que os sentimentos vivenciados nesse processo podem interfir na vida dessas mulheres, e de forma negativa. Mas, que apesar dessa situação, estas expressam sentimentos ambíguos, pois mesmo com o risco gestacional, muitas mostram-se felizes pela dádiva de ser mãe.

Resumen Introducción: El embarazo se considera un evento único y memorable en la vida de una mujer. El embarazo de alto riesgo es una experiencia estresante debido a los riesgos a los que están expuestas tanto la madre como su bebé y a los cambios que afectan negativamente su equilibrio emocional. Objetivo: Identificar los sentimientos experimentados por las mujeres embarazadas frente a un embarazo de alto riesgo. Metodología: Descriptivo y exploratorio con enfoque cualitativo, con una muestra a conveniencia compuesta por mujeres con embarazos de alto riesgo, seleccionadas según la disponibilidad del servicio de hospitalización, hasta la saturación de las entrevistas. La recopilación de datos se llevó a cabo durante un período de dos meses a través de entrevistas guiadas. Los datos fueron analizados utilizando la técnica de análisis de contenido según Minayo. Resultados: Participaron 37 mujeres y los resultados se organizaron en las siguientes categorías: cómo se realizó el diagnóstico de alto riesgo; sentimientos al descubrir que el embarazo era de riesgo; sentimientos con respecto al apoyo familiar en relación con el embarazo de alto riesgo. Los sentimientos relatados por las mujeres embarazadas y posparto que vivieron un embarazo de alto riesgo evidencian los impactos que tiene este evento no solo en la salud física sino, especialmente, en el bienestar emocional, pues deja a las mujeres embarazadas en un estado de vulnerabilidad. Conclusión: El estudio nos permitió darnos cuenta de que los sentimientos experimentados en este proceso pueden interferir en la vida de estas mujeres de manera negativa. Sin embargo, a pesar de esta situación, muchas de ellas expresan sentimientos ambiguos, porque, incluso con el riesgo gestacional, están agradecidas por el regalo de la maternidad.

Abstract Introduction: Pregnancy is considered a unique and memorable event in a woman's life. High-risk pregnancy is a stressful experience due to the risks to which the mother and the baby are exposed, and due to the changes that negatively affect their emotional balance. Objective: To identify the feelings experienced by pregnant women facing high-risk pregnancy. Method: Descriptive and exploratory, employing a qualitative approach, the study featured a convenience sample of women with high-risk pregnancies, selected based on inpatient service availability, until interview saturation was achieved. Data collection was conducted over a two-month period through scripted interviews. Data analysis was performed utilizing Minayo's content analysis technique. Results: Thirty-seven women participated in the study. The results were categorized as follows: How the high-risk diagnosis was determined; Feelings upon discovering the pregnancy was high-risk; Feelings regarding family support regarding the high-risk pregnancy. The feelings reported by pregnant and postpartum women who experienced high-risk pregnancies clearly reveal the impacts this event has, not only on physical health, but especially on emotional well-being, leaving the pregnant women in a vulnerable state. Conclusion: The study allowed us to realize that the feelings experienced in this process can negatively interfere in the lives of these women. However, despite this situation, many of them express mixed feelings, because even with the gestational risk, they are grateful for the gift of motherhood.

O Treinamento Resistido Atenua a Remodelação Cardíaca Induzida por uma Dieta Hiperlipídica em Roedores: Uma Revisão Sistemática / Resistance Exercise Training Mitigates Cardiac Remodeling Induced by a High-Fat Diet in Rodents: A Systematic Review

Resumo Fundamento A obesidade está associada ao desenvolvimento de doenças cardiovasculares e constitui um grave problema de saúde pública. Em modelos animais, a alimentação com uma dieta hiperlipídica (DH) compromete a estrutura e a função cardíaca e promove estresse oxidativo e apoptose. O treinamento resistido (TR), entretanto, tem sido recomendado como coadjuvante no tratamento de doenças cardiometabólicas, incluindo a obesidade, porque aumenta o gasto energético e estimula a lipólise. Objetivo Na presente revisão sistemática, nosso objetivo foi avaliar os benefícios do TR no coração de ratos e camundongos alimentados com DH. Métodos Foram identificados estudos originais por meio de busca nas bases de dados PubMed, Scopus e Embase de dezembro de 2007 a dezembro de 2022. O presente estudo foi conduzido de acordo com os critérios estabelecidos pelo PRISMA e registrado no PROSPERO (CRD42022369217). O risco de viés e a qualidade metodológica foram avaliados pelo SYRCLE e CAMARADES, respectivamente. Os estudos elegíveis incluíram artigos originais publicados em inglês que avaliaram desfechos cardíacos em roedores submetidos a mais de 4 semanas de TR e controlados por um grupo controle sedentário alimentado com DH (n = 5). Resultados Os resultados mostraram que o TR atenua o estresse oxidativo cardíaco, a inflamação e o estresse do retículo endoplasmático. Também modifica a atividade de marcadores de remodelamento estrutural, apesar de não alterar parâmetros biométricos, parâmetros histomorfométricos ou a função contrátil dos cardiomiócitos. Conclusão Nossos resultados indicam que o TR parcialmente neutraliza o remodelamento cardíaco adverso induzido pela DH, aumentando a atividade dos marcadores de remodelamento estrutural; elevando a biogênese mitocondrial; reduzindo o estresse oxidativo, marcadores inflamatórios e estresse do retículo endoplasmático; e melhorando os parâmetros hemodinâmicos, antropométricos e metabólicos.

Abstract Background Obesity is associated with the development of cardiovascular diseases and is a serious public health problem. In animal models, high-fat diet (HFD) feeding impairs cardiac structure and function and promotes oxidative stress and apoptosis. Resistance exercise training (RT), however, has been recommended as coadjutant in the treatment of cardiometabolic diseases, including obesity, because it increases energy expenditure and stimulates lipolysis. Objective In this systematic review, we aimed to assess the benefits of RT on the heart of rats and mice fed HFD. Methods Original studies were identified by searching PubMed, Scopus, and Embase databases from December 2007 to December 2022. This study was conducted in accordance with the criteria established by PRISMA and registered in PROSPERO (CRD42022369217). The risk of bias and methodological quality was evaluated by SYRCLE and CAMARADES, respectively. Eligible studies included original articles published in English that evaluated cardiac outcomes in rodents submitted to over 4 weeks of RT and controlled by a sedentary, HFD-fed control group (n = 5). Results The results showed that RT mitigates cardiac oxidative stress, inflammation, and endoplasmic reticulum stress. It also modifies the activity of structural remodeling markers, although it does not alter biometric parameters, histomorphometric parameters, or the contractile function of cardiomyocytes. Conclusion Our results indicate that RT partially counteracts the HFD-induced adverse cardiac remodeling by increasing the activity of structural remodeling markers; elevating mitochondrial biogenesis; reducing oxidative stress, inflammatory markers, and endoplasmic reticulum stress; and improving hemodynamic, anthropometric, and metabolic parameters.

Adição da Troponina Ultrassensível à Avaliação de Risco Perioperatório Melhora a Capacidade Preditiva de Morte em Pacientes Submetidos à Cirurgia Não Cardíaca / Addition of High-Sensitivity Troponin to Perioperative Risk Assessment Improves the Predictive Ability of Death in Non-Cardiac Surgery Patients

Resumo Fundamento A estratificação ode risco é uma importante etapa na avaliação perioperatória. No entanto, os principais escores de risco não incorporam biomarcadores em seus conjuntos de variáveis. Objetivo Avaliar o poder incremental da troponina à estratificação de risco tradicional. Métodos Um total de 2230 pacientes admitidos na unidade de terapia intensiva após cirurgia não cardíaca foram classificados de acordo com três tipos de risco: Risco Cardiovascular (RCV), Índice de Risco Cardíaco Revisado (IRCR), e Risco Inerente da Cirurgia (RIC). O principal desfecho foi mortalidade por todas as causas. A regressão de Cox foi usada, assim como a estatística C antes e após a adição de troponina ultrassensível (pelo menos uma medida até três dias após a cirurgia). Finalmente, o índice de reclassificação líquida e a melhoria de discriminação integrada foram usadas para avaliar o poder incremental da troponina para a estratificação de risco. O nível de significância usado foi de 0,05. Resultados A idade média dos pacientes foi 63,8 anos e 55,6% eram do sexo feminino. A prevalência de lesão miocárdica após cirurgia não cardíaca (MINS) foi 9,4%. Pacientes com um RCV elevado apresentaram uma maior ocorrência de MINS (40,1% x 24,8%, p<0,001), bem como pacientes com alto RIC (21,3 x 13,9%, p=0,004) e aqueles com IRCR≥3 (3,0 x 0,7%, p=0,009). Pacientes sem MINS, independentemente do risco avaliado, apresentaram taxa de mortalidade similar. A adição de troponina à avaliação de risco melhorou a capacidade preditiva de mortalidade em 30 dias e de mortalidade em um ano em todas as avaliações de risco. Conclusão A prevalência de MINS é mais alta na população de alto risco. No entanto, sua prevalência na população de risco mais baixo não é desprezível e causa um maior risco de morte. A adição da troponina ultrassensível melhorou a capacidade preditiva da avaliação de risco em todos os grupos.

Abstract Background Risk stratification is an important step in perioperative evaluation. However, the main risk scores do not incorporate biomarkers in their set of variables. Objective Evaluate the incremental power of troponin to the usual risk stratification Methods A total of 2,230 patients admitted to the intensive care unit after non-cardiac surgery were classified according to three types of risk: cardiovascular risk (CVR), Revised Cardiac Risk Index (RCRI); and inherent risk of surgery (IRS). The main outcome was all-cause mortality. Cox regression was used as well as c-statistics before and after addition of high-sensitivity troponin (at least one measurement up to three days after surgery). Finally, net reclassification index and integrated discrimination improvement were used to assess the incremental power of troponin for risk stratification. Significance level was set at 0.05. Results Mean age of patients was 63.8 years and 55.6% were women. The prevalence of myocardial injury after non-cardiac surgery (MINS) was 9.4%. High CVR-patients had a higher occurrence of MINS (40.1 x 24.8%, p<0.001), as well as high IRS-patients (21.3 x 13.9%, p=0.004) and those with a RCRI≥3 (3.0 x 0.7%, p=0.009). Patients without MINS, regardless of the assessed risk, had similar mortality rate. The addition of troponin to the risk assessment improved the predictive ability of death at 30 days and at 1 year in all risk assessments. Conclusion The prevalence of MINS is higher in the high-risk population. However, its prevalence in lower-risk population is not negligible and causes a higher risk of death. The addition of high-sensitivity troponin increased the predictive ability of risk assessment in all groups.

Parameters of pubertal growth spurt in children and adolescents living at high altitude in Peru

Abstract Objectives: The aim was to estimate the pubertal growth height of children and adolescents living in a high-altitude region of Peru using the Preece-Baines model 1 (1 PB). Methods: A cross-sectional study was conducted in schoolchildren from the department of Puno (Peru) between 3841 and 3874 masl. The age range was between 4 and 17 years. Standing height was evaluated. 1 PB was used to infer the mathematical and biological parameters of stature. Results: Mathematical parameters estimated by the 1 PB model reflected small residual standard error (RSE) values in both sexes (0.25 in boys and 0.27 in girls). In boys, the age at which peak velocity was reached (APHV) was estimated at 13.21 ± 0.33years. While in girls it was 9.96 ± 0.26years (p < 0.05). In general, girls reached APHV (y) 3.25 years earlier than boys. On the other hand, the growth velocity of maximum height [APHV (cm/y)] of boys was higher (6.33 ± 6.06 cm/y) relative to girls (6.06 ± 0.32 cm/y). Estimated final adult height (EFAH) in boys was reached at 166.020 ± 0.99 cm and height at maximum growth velocity (HPHV) was 153.07 ± 0.67 cm, while in girls they were significantly lower (EFAH; 153.74 ± 0.44 cm and HPHV: 139.73 ± 0.84 cm). Conclusions: This study showed that girls living in Puno at a high altitude in Peru reached APHV 3 years earlier than boys and at the same time reflected slower PHV. These results suggest that pubertal growth at high altitudes is slower in both sexes and especially in girls. Thus, modeling physical growth may be an important step in understanding the onset of puberty at different latitudes.

Comparison of the effectiveness of different high-flow devices in neonatal care

Abstract Objective: To evaluate the success rate of high-flow nasal cannula (HFNC) therapy using an adapted obsolete mechanical ventilator (MV), Optiflow™ and Vapotherm™ in newborns (NBs). Method: This was a retrospective observational study conducted in the neonatal intensive care unit (NICU). The sample comprised NBs who underwent HFNC therapy due to ventilatory dysfunction, for weaning from non-invasive ventilation (NIV), or post-extubation. The three groups, stratified according to gestational age (GA) and birth weight, and corrected GA and weight at the beginning of HFNC use, were as follows: Optiflow ™, Vapotherm ™, and obsolete Mechanical Ventilator (MV) adapted for high flow therapy. Subsequently, the NBs were divided into a success group (SG) and a failure group (FG). HFNC success was defined as a therapy duration exceeding 72 h. Results: A total of 209 NBs were evaluated, with 31.1 % using HFNC due to ventilatory dysfunction, 2.4 % after extubation, and 66.5 % after NIV weaning. HFNC success rate was observed in 90.9 % of the NBs, with no difference between equipment types (Vapotherm ™, Optiflow ™, and adapted VM). Conclusion: Different types of HFNC equipment are equally effective when used in neonatology for respiratory dysfunction, as a method of weaning from NIV and post-extubation. Adapted obsolete MV can be an alternative for HFCN therapy in resource-constrained settings.

Prevención de la preeclampsia. Desde la dieta hasta la aspirina: revisión de la literatura

Introducción y objetivo: Explorar las estrategias de prevención de la preeclampsia que se han propuesto a lo largo de la historia. Método: Revisión narrativa de la literatura sobre la evidencia científica histórica disponible entre 2016 y 2023 acerca de la aspirina y otras estrategias de prevención de la preeclampsia, en bases de datos bibliográficas computarizadas de estudios publicados en revistas indexadas. Resultados: Varios estudios confirman la efectividad de la aspirina para prevenir la preeclampsia en población de alto riesgo, siendo un medicamento con bajo riesgo de complicaciones, con mayor evidencia de efectividad si se inicia antes de las 16 semanas de gestación y con un aparente efecto dependiente de la dosis. Intervenciones como la disminución del consumo de sal, el reposo en cama, la suplementación con ácidos grasos, antioxidantes, L-arginina, zinc o magnesio, y el uso de diuréticos o de inhibidores de la bomba de protones, no han mostrado su utilidad en la prevención de la preeclampsia. Conclusiones: La aspirina a dosis baja es un medicamento seguro en el embarazo y efectivo para prevenir la preeclampsia en población de alto riesgo. Es la estrategia de prevención más ampliamente estudiada a lo largo de la historia para la disfunción endotelial durante la gestación.

Introduction and objective: To explore the different prevention strategies for preeclampsia that have been proposed throughout the history. Method: A narrative review of the historical, scientific evidence available between 2016 and 2021 on aspirin and other preeclampsia prevention strategies in computerized bibliographic databases of studies published in indexed journals. Results: Several studies confirm the effectiveness of aspirin to prevent preterm preeclampsia in high-risk populations, considering this as a safe drug with low risk of complications, with greater evidence of effectiveness when started before 16 weeks of gestation and apparently with a dose-dependent effect. Interventions such as reducing salt intake, bed rest, supplementation with fatty acids, antioxidants, L-arginine, zinc, magnesium, the use of diuretics or proton pump inhibitors have not shown its usefulness in the prevention of high risk preeclampsia patients. Conclusions: Low-dose aspirin is a safe drug in pregnancy and is effective to prevent preeclampsia in high-risk populations. Is the most widely studied throughout history prevention strategy for endothelial dysfunction during pregnancy.

Percepção dos alunos do ensino médio em relação a uma proposta de ensino das lutas nas aulas de Educação Física / Perception of high school students in relation to a proposal for teaching martial arts in Physical Education classes / Percepción de estudiantes de secundaria en relación a una propuesta de enseñanza de lucha en las clases de Educación Física

O objetivo do estudo foi analisar a percepção dos alunos do Ensino Médio em relação às lutas enquanto unidade temática nas aulas de Educação Física. Para tanto, a pesquisa se caracterizou como de natureza aplicada, do tipo descritiva, com a participação de 17 alunos do Ensino Médio. A pesquisa foi realizada em dois momentos, sendo o primeiro referente ao desenvolvimento de uma intervenção pedagógica do conteúdo de lutas, e o segundo a partir da aplicação de um questionário. Os resultados apontaram que 82% dos participantes usufruíram de uma prática positiva e prazerosa e 94% dos participantes afirmaram ausência de violência. Assim, compreende-se que as lutas na escola se configuram como um mediador na transformação das apreciações de concepções pelos participantes (AU).

The aim of the study was to analyze the perception of high school students in relation to martial arts as a content in Physical Education classes. Therefore, the research was characterized as being of an applied nature, of the descriptive type, with the participation of 17 high school students. The research was carried out in two moments, the first one referring to the development of a pedagogical intervention on the content of martial arts, and the second one based on the application of a questionnaire. The results showed that 82% of the participants en-joyed a positive and pleasant practice and 94% of the participants stated that there was no violence in the classes. Thus, it is understood that the development of martial arts at school was configured as a mediator in the transformation of the appreciation of conceptions by the participants (AU).

La investigación se realizó en dos momen-tos, el primero referido al desarrollo de una intervención pedagógica so-bre el contenido de las peleas, y el segundo a partir de la aplicación de un cuestionario. Los resultados mostraron que el 82% de los participantes disfrutaron de una práctica positiva y agradable y el 94% de los pantes afirmó que no hubo violencia en las clases. Así, se entiende que el desarrollo de las luchas en la escuela se configuró como un mediador en la transformación de la apreciación de las concepciones por parte de los participantes (AU).

Ansiedad en estudiantes de secundaria en tiempos de pandemia: revisión Sistemática / Anxiety in high school students in times of pandemic: systematic Review / Ansiedade em estudantes do ensino médio em tempos de Pandemia: Revisão sistemática

El aislamiento social y el confinamiento forzado debido a la pandemia tuvo graves efectos en la salud mental de los estudiantes, que se manifestó cómo ansiedad y estrés. Objetivo. La investigación tuvo como propósito analizar los niveles de ansiedad en estudiantes de secundaria. Metodología. La búsqueda de información se realizó en las bases de datos Scopus y Ebsco, utilizando las ecuaciones: "Anxiety AND High school students", "Trait Anxiety AND High school students", "State anxiety AND High school students"; la información recabada se almacenó en la bandeja de Mendeley; dicha información fue analizada por títulos, resumen, palabras clave, resultados y conclusiones. El análisis de la información encriptada en Mendeley contó con 35 artículos, de los cuales 30 fueron cuantitativos y 5 cualitativos; además, el análisis por países demostró que las investigaciones sobre este tópico se realizaron con mayor énfasis en Brasil (6), en España (4) y en EE.UU. (4). El análisis de los aportes evidenció que la carencia de aparatos tecnológicos y el cambio de una educación presencial a otra virtual tuvo consecuencias inusuales de estrés y ansiedad en estudiantes y docentes. Además, se observó incremento en la agresividad, problemas en la salud mental, insomnio, pérdida del apetito entre otros. Conclusión. El confinamiento social y los cambios abruptos en la educación generaron en los agentes educativos trastornos en la salud mental y emocional.

Conclusion: the LIFT procedure appears to be an effective and safe alternative for the treatment of low and high transsphincteric fistulas, since it does not alter the anatomy or continence. (AU)

Cánula Nasal de Alto Flujo Asimétrica: una Revisión Narrativa / Asymmetrical High Flow Nasal Cannula: a Narrative Review

Los sistemas de Cánula nasal de alto flujo (CNAF) han sido ampliamente utilizados en el campo clínico como soporte no invasivo en el manejo de la falla respiratoria aguda (sobre todo hipoxémica) y cuidados post extubación. Clínica y fisiológicamente, las cánulas nasales de alto flujo son capaces de entregar un flujo de oxigeno alto que, debido a que ese gas se encuentra optimamente humidificado y calefaccionado, permite una mejor tolerancia por parte del paciente al ser comparada con las cánulas de oxigeno tradicionales. Por otra parte, este alto. Flujo es capaz de generar una presión positiva al final de la espiración (CPAP) en la vía área y favorecer tanto en barrido de dióxido de carbono (CO2) desde la vía aérea superior, lo que disminuye el trabajo respiratorio del paciente y mejora su confort.. Sin embargo; aún existe un alto porcentaje de pacientes que fracasan la terapia con CNAF y requiere soportes mas complejos como la ventilación mecánica, ya sea imvasiva o no. Estos resultados con la terapia CNAF pueden ser influidos por aspectos técnicos como, por ejemplo, la turbulencia que pueden generar estos sistemas a nivel de la región nasal. Por esta razón se han desarrollado nuevas tecnologías en el diseño y uso de interfaces para suministrar este alto flujo. Una de estas innovaciones es el uso de cánulas asimétricas, las que potencian los beneficios fisiológicos que entrega una cánula de alto flujo convencional. La presente revisión pretende exponer las principales diferencias que presenta el sistema de alto flujo convencional versus la nueva interface asimétrica.

High-flow nasal cannula (HFNC) systems have been widely used in the clinical field as non-invasive support in the management of acute respiratory failure (especially hypoxemic) and post-extubation care. Clinically and physiologically, high flow nasal cannulas are capable of delivering a high flow of oxygen which, because this gas is optimally humidified and heated, allows better tolerance by the patient when compared to traditional oxygen cannulas. . On the other hand, this high. Flow is capable of generating positive pressure at the end of expiration (CPAP) in the airway and favoring the sweep of carbon dioxide (CO2) from the upper airway, which reduces the patient's respiratory work and improves their comfort. .. However; There is still a high percentage of patients who fail therapy with HFNC and require more complex supports such as mechanical ventilation, whether invasive or not. These results with HFNC therapy can be influenced by technical aspects such as, for example, the turbulence that these systems can generate in the nasal region. For this reason, new technologies have been developed in the design and use of interfaces to provide this high flow. One of these innovations is the use of asymmetric cannulas, which enhance the physiological benefits provided by a conventional high-flow cannula. The present review aims to expose the main differences that the conventional high flow system presents versus the new asymmetric interface.

Frequência e distribuição do gene da α-actinina-3 e sua associação em atletas brasileiras de voleibol / Frequency and distribution of the α -actinin-3 gene and its association in brazilian volleyball athletes

Introduction: The ACTN3 gene encodes the α-actinin-3 protein in the Z lines of the sarcomere, which anchors the actin protein in the contractile apparatus, present exclusively in type II muscle fibers, presenting greater glycolytic capacity, which is essential for sports with high-energy actions. intensity and short duration as is the case with Volleyball. Objective: To verify the frequency and distribution of the ACTN3 gene, RR and RX genotypes that express α-actinin-3 (EX α-actinin-3), and XX genotype that do not express α-actinin-3 (NE α-actinin-3) and its association with Brazilian volleyball athletes. Materials and Methods: Nine-seven (97) athletes from the women's volleyball super league took part in the study. Body mass, height and age were evaluated to characterize the sample. Salivary samples were analyzed using (PCR) in real time, to determine the genotypes, and, to verify the association of the genotype with the status of volleyball athlete in the three categories (National Teams, Brazilian National Team and Brazilian Olympic Team), the test was carried out Chi-square of independence (χ²). To obtain the odds ratio of the outcome, a log linear regression analysis was performed. All tests were carried out using the JAMOVI 2.4 (2023) statistical software. Results: Among the athletes in the sample competing in the National Teams competition, 91.8% have the EX-α-actinin-3 genotype. When we consider Brazilian National Team competitions, 93.7% have the EX-α-actinin-3 genotype. Athletes who play for the Brazilian Olimpic Team, 100% of the sample have the EX-α-actinin-3 genotype. Considering that in the world population, the frequency is 80%, it is possible to verify that as you approach the athletes who participate in the women's team there is a greater participation of athletes with the EX-α-actinin-3 genotype. Furthermore, there was an association between the genotypes that EX α-actinin-3 and the National category, with the status of elite athlete, where (χ²) obtained the p value (0.023) and the rate ratio (2.71) for the outcome of the genotypes (EX α-actinin-3) being elite athletes. Conclusion: The athlete's genetic characteristics, environment, nutrition, physical, technical and tactical preparation are some of the factors that contribute to sports performance. However, the results of the present study suggest that athletes with RR and RX genotypes that express α-actinin-3, present in type II muscle fibers, seem to confer an advantage when playing high-performance volleyball.

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.
