Barreras y facilitadores del acceso al tamizaje de cáncer colorrectal / Barriers and facilitators of colorectal cancer screening access

Resumen Introducción : El cáncer colorrectal (CCR) es un pro blema de salud a nivel global. En el sector público de Bahía Blanca, el tamizaje de CCR es oportunista, por solicitud de sangre oculta en materia fecal (SOMF). El objetivo de este trabajo es describir el acceso al tamiza je de CCR de la población con cobertura pública exclu siva que reside en el área programática 2 de la ciudad entre 2019 y 2021, y relevar las barreras y facilitadores que lo determinan. Métodos : Se estimó la tasa de uso anual y acumula da de SOMF. Las barreras y facilitadores se relevaron a través de 41 entrevistas individuales semi-estructuradas al personal de salud del área programática, el Hospital Municipal, Secretaría de Salud y usuarios/no usuarios del sistema. Resultados : La tasa acumulada de uso de SOMF en el período fue 4.8%. Entre las barreras al tamizaje per cibidas se destacan: la dificultad en el acceso a estudios de mayor complejidad para pacientes con SOMF+, el desconocimiento y falta de percepción del CCR como un problema de salud por parte de la población y la baja adherencia de los profesionales a los lineamientos. La territorialidad y el vínculo de los centros de salud con la población, y la predisposición de usuarios y profesio nales a incorporar el tamizaje surgen como facilitadores del mismo. Conclusiones : El relevamiento de las barreras orien tará el diseño de estrategias adaptadas al contexto que permitan en el futuro reforzar el tamizaje.

Abstract Introduction : Colorectal cancer (CRC) is a global health problem. In the public sector of Bahía Blanca, CRC screening is opportunistic, through the request of fecal occult blood test (FOBT). The objective of this study is to describe access to CRC screening for the population with exclusive public coverage residing in the program matic area 2 of the city between 2019 and 2021, and to identify the barriers and facilitators that determine it. Methods : The annual and cumulative usage rate was estimated based on the number of patients who requested FOBT. The barriers and facilitators were studied through 41 semi-structured individual inter views to healthcare staff from the area, the Municipal Hospital, Health Secretariat and users/non-users of the system. Results : The cumulative usage rate of FOBT during the period was less than 5%. Among the perceived bar riers to screening, we found: the difficulties in accessing more complex studies for patients with positive FOBT, the lack of population awareness and perception of CRC as a health problem, the low adherence of professionals to guidelines. The territoriality and link of health centers with the population, as well as the willingness of users and professionals to incorporate screening, emerge as facilitators. Conclusion : The identification of barriers and facilita tors will allow the design of context-adapted strategies that will strengthen screening in the future.

Efectividad de estrategias para incrementar la adherencia al tamizaje de cáncer colorrectal: una revisión sistemática / Effectiveness of strategies to increase adherence to colorectal cancer screening: a systematic review

Resumen Introducción : En Argentina la cobertura al tamizaje de cáncer colorrectal (CCR) es muy baja. El objetivo de esta revisión fue relevar y sintetizar la evidencia sobre la efectividad de estrategias dirigidas a incrementar la adherencia al tamizaje de CCR del personal de salud y población con riesgo promedio. Métodos : Revisión de revisiones sistemáticas (RS) que evaluaron la efectividad de dichas estrategias. Bús queda en bases de datos electrónicas, meta-buscadores, biblioteca Cochrane y búsqueda manual. Aplicación de criterios de elegibilidad e inclusión; con evaluación de la calidad de las RS a través del AMSTAR-II y la certeza de la evidencia por el método GRADE. Síntesis temática sobre la base de la taxonomía de estrategias propuesta por Dougherty (dirigidas al paciente/comunidad; a pro fesionales; otro tipo de estrategias). Resultados : Se identificaron 635 estudios; 36 fueron elegibles y 11 se descartaron por no contar con cali dad suficiente, incluyéndose 10 RS. Se identificó una multiplicidad de estrategias de efectividad variada, la mayoría dirigida a la población. Entre estas, destacan la educación, el auto-test con recolección en lugares específicos y recordatorios. En el caso de profesionales, solo educación y recordatorios mostraron ser efectivas. La combinación de estrategias mostró tener mayor efec tividad que las estrategias aisladas. Conclusiones : Es mayor la evidencia sobre estrategias dirigidas a la población que a profesionales. Las estrate gias combinadas demostraron tener mayor efectividad, lo que destaca la necesidad de explorar, en cada con texto, las barreras en la población y en los profesionales para priorizar y combinar aquellas que demostraron ser efectivas y tendrían mayor impacto.

Abstract Introduction : Coverage for colorectal cancer screening in Argentina is very low. The objective of this review is to assess and synthesize the evidence on the effectiveness of strategies aimed at increasing adherence to colorectal cancer screening among healthcare personnel and the general population at average risk. Methods : A review of systematic reviews (SRs) that evaluated the effectiveness of these strategies was con ducted. Searches were performed in electronic data bases, meta-search engines, the Cochrane Library, and through manual searching. Eligibility and inclusion criteria were applied, with assessment of the quality of the SRs using AMSTAR II and the certainty of evidence using the GRADE approach. Thematic synthesis was con ducted based on the taxonomy of strategies proposed by Dougherty (patient/community-targeted, professional-targeted, and other types of strategies). Results : A total of 635 studies were identified, with 36 deemed eligible and 11 excluded due to insufficient quality, resulting in the inclusion of 10 SRs. A multi plicity of strategies with varying effectiveness were identified, with the majority targeting the population. Among these, education, self-testing with specimen collection at specific locations, and reminders stood out. For professionals, only education and reminders showed effectiveness. Combined strategies demonstrated greater effectiveness than isolated strategies. Conclusions : There is more evidence on strategies targeting the population than professionals. Combined strategies showed greater effectiveness, highlighting the need to explore barriers in both the population and professionals in each specific context in order to priori tize and combine those that have proven effective and would have a greater impact.

Prevalência e fatores associados à realização dos exames de triagem neonatal no Brasil: comparação da PNS 2013 e 2019 / Prevalence of neonatal screening and associated factors in Brazil: a comparison of the 2013 and 2019 National Health Surveys

Resumo Analisou-se a prevalência e fatores associados à realização da Triagem Neonatal Completa (TNC) entre crianças (<2 anos de idade) no Brasil incluídas na Pesquisa Nacional Saúde 2013 (n=4.442) e 2019 (n=5.643). Estudo transversal comparou as estimativas de prevalência e intervalos de confiança de 95% (IC95%) da TNC (testes do olhinho, orelhinha e pezinho). Diferenças foram consideradas estatisticamente significante ao nível de 5%. Regressões de Poisson bruta e ajustada foram realizadas para estimar Razões de Prevalência (RP) e IC95% para a associação das variáveis socioeconômicas, demográficas e de saúde com a TNC. Verificou-se aumento estatisticamente significante da TNC: 67,4% (IC95%: 65,5-69,3) em 2019, ante 49,2% (IC95%: 47,1-51,3) em 2013. Porém, ainda existem desigualdades e defasagens entre os estados da federação e variáveis sociodemográficas. Entre os anos, a TNC foi menor nas crianças de cor/raça parda e preta, dos três piores quintis de renda, sem plano de saúde, cadastradas na Estratégia de Saúde da Família, da região norte, de cidades do interior e da zona rural do Brasil. Apesar de o aumento da prevalência de TNC, desigualdades e defasagens individuais e contextuais permaneceram, indicando os desafios das políticas de saúde.

Abstract This study analyzed the prevalence of complete neonatal screening (CNS) of children aged under 2 years in Brazil and associated factors using data from the 2013 (n=4,442) and 2019 (n=5,643) national health surveys. We conducted a cross-sectional study to compare prevalence of CNS (eye, ear and heel prick tests) adopting 95% confidence intervals (95%CI) and a 5% significance level. Crude and adjusted Poisson regression was performed to estimate prevalence ratios (PR) and 95%CI to assess the association between socioeconomic, demographic and health variables and CNS. There was a statistically significant increase in CNS prevalence, from 49.2% (95%CI: 47.1-51.3) in 2013 to 67.4% (95%CI: 65.5-69.3) in 2019. However, large disparities persist across states and between sociodemographic groups. In both years, CNS prevalence was lowest among brown and black children, those from families in the three lowest income quintiles, children without health insurance, those from families registered in the Family Health Strategy and children living in the North, cities outside the state capital/metropolitan regions and rural areas. Despite the increase in prevalence of CNS, deep individual and contextual inequalities persist, posing challenges for health policies.

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

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

Phytochemical Screening and in vitro Anticancer Activity of Some Medicinal Plants Grown in the Kingdom of Saudi Arabia / Cribado Fitoquímico y Actividad Anticancerígena in vitro de Algunas Plantas Medicinales Cultivadas en el Reino de Arabia Saudita

SUMMARY: This study evaluated the phytochemical screening, antioxidant capacity, and in vitro anticancer activities of four plants namely, Gypsophila capillaris, Anabasis lachnantha, Haloxylon salicornicum, and Horwoodia dicksoniae which belong to four different families: Caryophyllaceae, Amaranthaceae, Chenopodiaceae, Brassicaceae, respectively. The total phenolics, anthocyanins, saponins, total antioxidant capacity (TAC), and DPPH assays were determined by spectrophotometer. In vitro anticancer activity was assessed using two human cancer cell lines; hepatocellular carcinoma (HepG-2) and breast adenocarcinoma (MCF-7) to estimate the inhibition concentration 50 % (IC50). The results showed that H. dicksoniae has the highest concentrations of phenolics and saponins, while H. salicornicum has the highest DPPH. The highest concentration of TAC was found in G. capillaries. Among the tested extracts, G. capillaries and H. salicornicum have the potential activity against MCF-7 and HepG-2 cell lines in vitro. The content of polyphenols in G. capillaries was profiled by high-performance liquid chromatography (HPLC). The highest concentration among the phenolic compounds was chlorogenic (60.8 µg/ml) while the highest concentration among the flavonoid compounds was hesperidin (1444.92 µg/ml). In summary, G. capillaries and H. salicornicum extracts have potent anticancer activity against HepG-2 and MCF-7 cell lines.

Este estudio evaluó la detección fitoquímica, la capacidad antioxidante y las actividades anticancerígenas in vitro de cuatro plantas, Gypsophila capillaris, Anabasis lachnantha, Haloxylon salicornicum y Horwoodia dicksoniae, que pertenecen a cuatro familias diferentes: Caryophyllaceae, Amaranthaceae, Chenopodiaceae y Brassicaceae, respectivamente. Los ensayos de fenólicos totales, antocianinas, saponinas, capacidad antioxidante total (TAC) y DPPH se determinaron mediante espectrofotómetro. La actividad anticancerígena in vitro se evaluó utilizando dos líneas celulares de cáncer humano; carcinoma hepatocelular (HepG-2) y adenocarcinoma de mama (MCF- 7) para estimar la concentración de inhibición del 50 % (IC50). Los resultados indicaron que H. dicksoniae tiene las concentraciones más altas de fenólicos y saponinas, mientras que H. salicornicum tiene el DPPH más alto. La mayor concentración de TAC se encontró en G. capillaries. Entre los extractos probados, G. capillaries y H. salicornicum tienen actividad potencial contra líneas celulares MCF-7 y HepG-2 in vitro. El contenido de polifenoles en G. capillaries se perfiló mediante cromatografía líquida de alta resolución (HPLC). La concentración más alta entre los compuestos fenólicos fue clorogénica (60,8 µg/ml), mientras que la concentración más alta entre los compuestos flavonoides fue la hesperidina (1444,92 µg/ml). En resumen, los extractos de Gypsophila capillaris y H. salicornicum tienen una potente actividad anticancerígena contra las líneas celulares HepG-2 y MCF-7.

Antecedentes En Chile, la prevalencia del Trastorno por Déficit de Atención con Hiperactividad (TDAH) se estima en un 10%. Frente a esta realidad, las políticas públicas promueven la detección oportuna de esta condición, suscitándose sin embargo problemas de sobre y sub-diagnóstico atribuibles a la falta de escalas actualizadas. Objetivo El propósito de este estudio fue evaluar las propiedades psicométricas de la escala Conners-3 en su forma abreviada de auto-reporte en niños y adolescentes chilenos. Método Se aplicó el Conners-3, y una medida de validez convergente (BRIEF-2), a una muestra no probabilística (n = 265) de estudiantes de enseñanza básica y media (8-18 años). Se efectuó un análisis de la correlación ítem-test e inter-escalar, seguido de un análisis factorial confirmatorio (AFC), finalizando con un análisis de consistencia interna. Resultados Todos los ítems presentaron una correlación ítem-escala aceptable. La estructura interna de cinco factores del AFC coincide con la original, las cuales además presentaron una consistencia interna aceptable y evidencia de validez convergente así como divergente. Conclusiones La escala Conners-3 presenta propiedades psicométricas aceptables para ser usada en la fase de detección del TDAH, recomendándose su uso como parte de una evaluación integral que incorpore otros métodos de evaluación.

Background In Chile, it is estimated that the prevalence of Attention-Deficit/Hyperactivity Disorder (ADHD) is at 10%. Faced with this reality, public policies promote the timely detection of this condition; however, this situation generates over and underdiagnosis problems attributable to the lack of updated scales. Objective The purpose of this study was to assess the psychometric properties of the Conners-3 Rating Scale in its self-report short form in Chilean children and adolescents. Method The Conners-3 Self-report Scale and a convergent validity measure (BRIEF-2) were applied to a non-probability sample (n = 265) of elementary and high school students (8 to 18 years old). A confirmatory factor analysis (CFA) was carried out, in addition to an internal consistency analysis and an item-total and inter-scale correlation analysis. Results All the items presented an acceptable item-scale correlation. The five-factor internal structure of the CFA coincides with the original. Scales also presented an acceptable internal consistency and evidence of convergent validity. Conclusions the Conners-3 Self-report Scale presents acceptable psychometric properties for use in the detection phase of ADHD; furthermore, its use is suggested as part of a comprehensive assessment that incorporates other assessment methods.

Características de recién nacidos hijos de madre con IgM positiva para el Virus Herpes Simplex

Introducción: El herpes connatal es una entidad infrecuente asociada a elevada morbimortalidad. La probabilidad de transmisión al recién nacido va de 5% al 85%. El diagnóstico se dificulta por falta de clínica, serología no confiable y por la no disponibilidad de PCR en los servicios públicos de países en vías de desarrollo. La IgM en gestantes podría ser utilizada como un marcador de sospecha para evaluar al neonato. Objetivo: Caracterizar a los recién nacidos, hijos de gestantes con IgM positiva para HVS 1-2 y la frecuencia de encefalitis en los infantes. Materiales y métodos : Estudio observacional, descriptivo, prospectivo, realizado de mayo de 2020 a octubre de 2021. Se incluyeron recién nacidos (RN) de madres con IgM positiva para Herpes Virus Simplex (HVS) a partir de la segunda mitad del embarazo. En el RN se realizó serología IgG e IgM, y además, PCR- RT para HVS 1-2 en sangre y/o LCR, excluyéndose los nacidos en otras maternidades y/o sin datos de serología materna. Resultados: 36 pacientes. Edad materna 28 años (DS + 4), 5% con antecedentes de HVS, 61% cesárea. 36% prematuros, 13% RCIU. Síntomas agudos en el RN 22%. De ellos, 19% plaquetopenia, 44% alteración de GOT. 63% PCR HVS en sangre y 44% en LCR. Se encontró hemorragia, hidrocefalia, leucomalacia en 27%. No se encontró diferencias en la expresión clínica por tipo de parto. Conclusiones: Los RN hijos de gestantes con IgM positiva para VHS desde la segunda mitad del embarazo o periparto, presentaron infección por VHS determinada por PCR en sangre o LCR, independiente de la vía del parto. El diagnóstico serológico en embarazadas permite la pesquisa, diagnóstico y tratamiento temprano del RN.

Introduction: neonatal herpes is a rare entity associated with high morbidity and mortality. The probability of transmission to the newborn ranges from 5% to 85%. The diagnosis is difficult due to the lack of clinical signs, unreliable serology and the non-availability of PCR in public services in developing countries. IgM in pregnant women could be used as a suspected marker to evaluate the neonate. Objective: To characterize newborn children of pregnant women with positive IgM for HSV 1-2 and the prevalence of encephalitis in infants. Materials and methods: Observational, descriptive, prospective study, carried out from May 2020 to October 2021. Newborns (NB) of mothers with positive IgM for Herpes Virus Simplex (HSV) from the second half of pregnancy were included. In newborns, IgG and IgM were performed, and in addition, PCR-RT for HSV 1-2 in blood and/or CSF, excluding those born in other hospitales and/or without maternal serology data. Results: We included 36 patients. Maternal age was 28 years (DS + 4), 5% with a history of HSV. 61% were delivered via cesarean section, 36% were premature, 13% had IUGR. 22% of the newborns had acute symptoms. 19% had thrombocytopenia, 44% had GOT alteration. 63% were PCR positive for HSV in serum and 44% were CSF-positive. Hemorrhage, hydrocephalus and leukomalacia were found in 27%. No differences were found in clinical expression by type of delivery. Conclusions: Newborns born to pregnant women with positive IgM for HSV from the second half of pregnancy or peripartum, presented HSV infection as determined by PCR in blood or CSF, regardless of the route of delivery. Serological diagnosis in pregnant women allows early screening, diagnosis and treatment of the NB.

Infección congénita por citomegalovirus, hipoacusia y tamizaje neonatal. Una actualización

El citomegalovirus congénito (CMVc) es la infección congénita más común y la principal causa no genética de hipoacusia congénita. Gran parte de los recién nacidos (RN) con CMVc sintomático desarrolla secuelas graves permanentes, donde la hipoacusia es la más frecuente. Sin embargo, el 90% de los casos se presenta en forma asintomática, pudiendo desarrollar secuelas auditivas tardías. El diagnóstico precoz de CMVc requiere un alto índice de sospecha. Actualmente, técnicas eficientes para su detección están disponibles, lo que facilita el diagnóstico en las primeras 3 semanas de vida. La terapia antiviral es la primera línea de tratamiento para el CMVc sintomático, logrando buenos resultados auditivos. A pesar de los avances en los métodos de detección y beneficios del tratamiento, los RN no son tamizados para CMVc. El tamizaje selectivo de CMVc en pacientes que no pasan el screening auditivo facilita la intervención precoz en los casos identificados, pero no permite detectar el número significativo de niños que presenta hipoacusia de aparición tardía. El tamizaje universal permite hacer seguimiento auditivo a los pacientes en riesgo de desarrollar hipoacusia sensorioneural (HSN) por CMVc, identificando así los casos de hipoacusia de aparición tardía, pero la costo-efectividad es aún controversial. Es necesario avanzar en una estrategia local para el tamizaje de CMVc, buscando reducir su impacto a nivel nacional.

Congenital cytomegalovirus (cCMV) is the most common congenital infection and the main non-genetic cause of congenital hearing loss. A significant number of newborns (NB) with symptomatic cCMV will develop permanent serious sequelae, being hearing loss the most frequent. However, 90% of the cases are asymptomatic and may develop late auditory sequelae. Early diagnosis of cCMV requires a high index of suspicion. Currently, efficient detection techniques for its detection are available, which facilitates diagnosis within the first 3 weeks of life. Antiviral therapy is the first line of treatment for symptomatic cCMV, achieving good hearing results. Despite advances in detection methods and the benefits of antiviral therapy, NB are not routinely screened for cCMV. Selective screening for cCMV in patients who fail newborn hearing screening facilitates early intervention in identified cases but fails to detect a significant number of children with late onset hearing loss. Universal screening allows hearing follow up in patients at risk of developing sensorineural hearing loss (SNHL) due to cCMV, thus identifying late-onset hearing loss cases, but cost-effectiveness is still controversial. It is necessary to advance in a local strategy for cCMV screening, aiming to reduce its national impact.

Profile of sexually transmitted infections among attendees of special clinics (Suraksha) at an apex regional sexually transmitted disease centre in North India ­ a five-year study

Introduction: Sexually transmitted infections (STIs) present significant global and national health challenges, particularly in India. Objective: To estimate the prevalence and characteristics of STIs among attendees at the Suraksha Clinic in the Apex Regional STD Centre, Safdarjung Hospital. Methods:Retrospective data from January 2018 to December 2022 were statistically analyzed using Excel and SPSS. The study included the examination for diagnosis of various STIs, such as syphilis, human immunodeficiency virus (HIV), gonorrhoea, chlamydiasis, trichomoniasis, candidiasis, bacterial vaginosis, chancroid, and genital herpes. Gender distribution and syndromic diagnoses, including vaginal/cervical discharge and genital ulcers, were also considered. Referrals to Integrated Counseling and Testing Centres for HIV testing were analyzed. Results: The outcomes reveal a substantial burden of STIs, with 3.06% showing reactivity to syphilis, 1.74% testing positive for HIV, 3.36% for gonorrhoea, 11.78% for chlamydiasis, 1.05% for trichomoniasis, 26.24% for candidiasis, 9.97% for bacterial vaginosis, 7.80% for chancroid, 11.64% for herpes genitalis, and 4.01% for other non-STIs. Attendees' interactions included 34.36% of referrals to Integrated Counseling and Testing Centres for HIV testing. The gender distribution showed 58.92% male and 40.94% female attendees. Conclusion: Syndromic diagnoses, including vaginal/cervical discharge (21.22%) and genital warts (8.00%), highlight prevalent conditions, necessitating routine screening, early detection, and targeted interventions for effective disease control and prevention. These findings underscore the significance of integrated screening, patient education, and proactive strategies to safeguard public health in the face of rising STI rates. (AU)

Conclusão: Os diagnósticos sindrômicos, incluindo corrimento vaginal/cervical (21,22%) e verrugas genitais (8,00%), destacam condições prevalentes, necessitando de exames de rotina, detecção precoce e intervenções direcionadas para controle e prevenção eficazes de doenças. Estas conclusões sublinham a importância do rastreio integrado, da educação dos pacientes e de estratégias proativas para salvaguardar a saúde pública diante do aumento das taxas de IST. (AU)

Depressive symptoms in pregnant women treated at the Hospital Infantil del Estado de Sonora / Sintomatología depresiva en embarazadas atendidas en el Hospital Infantil del Estado de Sonora

Abstract Introduction Pregnancy, being a situation of vulnerability and with its inherent changes, places women at a great risk of depression. In Mexico, the prevalence of probable depression in pregnant women treated at the Instituto Nacional de Perinatología, was 17.8%, assessed using the Edinburgh Perinatal Depression Scale (EPDS). To date, there are no data regarding this issue in Sonora. Objective To determine the prevalence of depressive symptoms in pregnant women treated at the Hospital Infantil del Estado de Sonora (México). Method An observational, descriptive, transversal, and prospective study was conducted in 2021, applying the EPDS in 168 2nd/3rd trimester pregnant women, selected by non-probabilistic sampling by consecutive cases. Sociodemographic variables, pathological/non-pathological, gynecological, and obstetrical personal history were explored. The analysis was performed using measures of central tendency and dispersion for quantitative variables; for qualitative variables, frequency and percentage; χ2 test to assess differences in distribution of depressive symptomatology by age and the rest of variables. Results A global prevalence of "probable depression" of 14.3% was determined. The majority, within 20-29 age group, with a partner and a planned/desired pregnancy. High school educational level, 50%. History of intimate partner violence, 54.2%. Almost 40%, primigravida. Substance use, denied. Overweight/obesity, in 70%. Discussion and conclusion There is a high prevalence of depressive symptoms during pregnancy, going unnoticed for reasons such as insufficient knowledge (patient/health care providers), since there is no routine screening. It is imperative to work on prevention, detection and treatment, since it entails multiple consequences at a binomial, family, and social level.

Resumen Introducción El embarazo, al ser una situación de vulnerabilidad y los cambios que conlleva, ubica a las mujeres en mayor riesgo de padecer depresión. En México, la prevalencia de probable depresión en embarazadas en el Instituto Nacional de Perinatología, fue del 17.8%, mediante la Escala de Depresión Perinatal de Edimburgo (EPDS). Hasta hoy, no se cuenta con datos en Sonora sobre este problema. Objetivo Determinar la prevalencia de sintomatología depresiva en embarazadas atendidas en el Hospital Infantil del Estado de Sonora (México). Método Se realizó un estudio observacional, descriptivo, transversal y prospectivo en 2021, utilizando la EPDS en 168 embarazadas cursando 2o/3er trimestre, seleccionadas por muestreo no probabilístico por casos consecutivos. Se exploraron variables sociodemográficas, antecedentes patológicos/no patológicos y ginecoobstétricos. El análisis se realizó mediante medidas de tendencia central y dispersión para variables cuantitativas; para cualitativas, frecuencia y porcentaje; prueba de χ2 para evaluar diferencias en distribución de sintomatología depresiva por edad y resto de variables. Resultados Se determinó prevalencia global de "probable depresión" de 14.3%. La mayoría, grupo etario 20-29 años, con pareja y embarazo planeado/deseado. Escolaridad preparatoria, 50%. Antecedente de violencia de pareja, 54.2%. Casi 40%, primigestas. Consumo de sustancias, negado. Sobrepeso/obesidad, en 70%. Discusión y conclusión Existe una alta prevalencia de sintomatología depresiva durante el embarazo, pasando desapercibida por motivos como conocimiento insuficiente (paciente y proveedores de salud), pues no se cuenta con un tamizaje rutinario. Es apremiante trabajar en prevención, detección y tratamiento, ya que conlleva múltiples consecuencias a nivel binomio, familiar y social.

Herramientas para el tamizaje de aneurisma de aorta abdominal / Tools for abdominal aortic aneurysm screening

Introducción. El aneurisma de la aorta abdominal (AAA) es la dilatación de la aorta abdominal mayor de 1,5 veces el diámetro esperado. Su prevalencia es variable, con tasas reportadas de hasta el 12,5 %. Se considera como causa de muerte de más de 10.000 personas al año en los Estados Unidos. El objetivo de esta revisión de la literatura fue describir los factores de riesgo y las herramientas de tamizaje de AAA. Métodos. Se realizó una búsqueda de la literatura utilizando dos ecuaciones en bases de datos electrónicas, empleando términos seleccionados de "Medical Subject Heading" (MeSH) y "Descriptores en Ciencias de la Salud" (DeCS). Se evaluó la calidad de los estudios con la herramienta STROBE (Strengthening the Reporting of Observational Studies in Epidemiology). Resultados. Se recolectaron 40 artículos y a partir de ellos se construyó el texto de revisión, identificando en estos, los factores de riesgo asociados al desarrollo de AAA, tales como sexo masculino, tabaquismo, hipertensión arterial, antecedente familiar y obesidad, entre otros. La diabetes mellitus parece actuar como factor protector. Dentro de los instrumentos de tamizaje, el ultrasonido abdominal es uno de los más usados. Conclusión. El AAA es una patología multifactorial. En la actualidad la ultrasonografía de aorta es el método de elección para el tamizaje, permitiendo la detección precoz. El tamizaje de AAA con métodos no invasivos, como el ultrasonido, es útil sobre todo en zonas con prevalencia alta de la patología y en pacientes con determinados factores de riesgo.

Introduction. Abdominal aortic aneurysm (AAA) is a dilation of the abdominal aorta greater than 1.5 times the expected diameter. Its prevalence is variable, with reported rates of up to 12.5%. It is considered the cause of death of more than 10,000 people a year in the United States. The objective of this literature review was to describe risk factors and screening tools for AAA. Methods. A literature search was conducted using two equations in electronic databases, using terms selected from "Medical Subject Heading" (MeSH) and "Descriptors in Health Sciences" (DeCS). The quality of the studies was evaluated with the STROBE (Strengthening the Reporting of Observational Studies in Epidemiology) tool. Results. Forty articles were collected and from them the review text was constructed, identifying the risk factors associated with the development of AAA, such as male sex, smoking, high blood pressure, family history and obesity, among others. Diabetes mellitus seems to act as a protective factor. Among the screening instruments, abdominal ultrasound is one of the most used. Conclusion. AAA is a multifactorial pathology. Currently, aortic ultrasonography is the method of choice for screening, allowing early detection. Screening for AAA with non-invasive methods, such as ultrasound, is useful especially in areas with a high prevalence of this pathology and in patients with certain risk factors.

Comparison between the KARVI scale and the Child Development Evaluation test (EDI) as a screening tool for suspected neurodevelopmental delay / Comparación entre la escala KARVI y la prueba de Evaluación del Desarrollo Infantil (EDI) como tamizaje para la sospecha de retraso en el neurodesarrollo

Abstract Background: Early detection of suspected neurodevelopmental delay allows for timely diagnosis and appropriate intervention, for which numerous screening tests have been developed. However, most are complex and impractical for health-care workers at the community level. This study aimed to validate the KARVI scale in the neurodevelopment assessment of children under 1 year of age. Methods: We conducted an observational, longitudinal, comparative, inferential, and prospective study. Healthy children without risk factors for developing neurodevelopmental delay from 0 to 12 months of age were evaluated remotely using the Zoom® application. The Child Development Evaluation Test and the KARVI scale were applied once a month for four consecutive months. Results: Fifty individuals were analyzed, with a predominance of males in 52%. Adequate percentages for a screening test were obtained in the first evaluation with a sensitivity of 70% (confidence interval [CI] 95% 34.75-93.33) and a specificity of 75% (CI 95% 58.8-87.31), and in the fourth evaluation with a sensitivity of 100% (CI 95% 29.4-100) and a specificity of 78.72% (CI 95% 64.34-89.3), being significant in both evaluations (p = 0.007 and p = 0.001, respectively). Conclusions: The KARVI scale has the elements to be an effective screening test for suspected neurodevelopmental delay, but more extensive studies are needed to obtain more reliable results.

Resumen Introducción: La identificación temprana de retraso en el neurodesarrollo permite un diagnóstico oportuno y una intervención apropiada. Para ello, se han creado diversas pruebas de tamizaje; sin embargo, la mayoría son complejas y poco prácticas para el personal de la salud a nivel comunitario. El objetivo del estudio fue realizar la validación de la escala KARVI en la valoración del neurodesarrollo en niños menores de un año. Métodos: Se realizó un estudio observacional, longitudinal, comparativo inferencial y prospectivo, en el cual se evaluaron, vía remota mediante la aplicación Zoom®, niños sanos de 0 a 12 meses de edad sin factores de riesgo para desarrollar retraso en el neurodesarrollo. Se aplicaron la prueba EDI (Evaluación del Desarrollo Infantil) y la escala KARVI una vez al mes por cuatro meses consecutivos. Resultados: Se analizaron 50 individuos, con predominio del sexo masculino en el 52%. Se obtuvieron porcentajes adecuados para una prueba de tamizaje tanto en la primera evaluación, con sensibilidad de 70% (IC 95% 34.75-93.33) y especificidad de 75% (IC 95% 58.8-87.31), como en la cuarta, con sensibilidad de 100% (IC 95% 29.4-100) y especificidad de 78.72% (IC 95% 64.34-89.3), con significación estadística en ambas evaluaciones (p = 0.007 y p = 0.001, respectivamente). Conclusiones: Se considera que la escala KARVI cuenta con los elementos para considerarla como una prueba de tamizaje efectiva para detectar retraso del neurodesarrollo, sin embargo. Sin requieren estudios más extensos para obtener resultados más confiables.

Anti-SARS-CoV-2 activity of small molecule inhibitors of cathepsin L / 药学学报

The coronavirus disease 2019 (COVID-19) is an acute infectious disease caused by the new severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection, which has led to serious worldwide economic burden. Due to the continuous emergence of variants, vaccines and monoclonal antibodies are only partial effective against infections caused by distinct strains of SARS-CoV-2. Therefore, it is still of great importance to call for the development of broad-spectrum and effective small molecule drugs to combat both current and future outbreaks triggered by SARS-CoV-2. Cathepsin L (CatL) cleaves the spike glycoprotein (S) of SARS-CoV-2, playing an indispensable role in enhancing virus entry into host cells. Therefore CatL is one of the ideal targets for the development of pan-coronavirus inhibitor-based drugs. In this study, a CatL enzyme inhibitor screening model was established based on fluorescein labeled substrate. Two CatL inhibitors IMB 6290 and IMB 8014 with low cytotoxicity were obtained through high-throughput screening, the half inhibition concentrations (IC50) of which were 11.53 ± 0.68 and 1.56 ± 1.10 μmol·L-1, respectively. SDS-PAGE and cell-cell fusion experiments confirmed that the compounds inhibited the hydrolysis of S protein by CatL in a concentration-dependent manner. Surface plasmon resonance (SPR) detection showed that both compounds exhibited moderate binding affinity with CatL. Molecular docking revealed the binding mode between the compound and the CatL active pocket. The pseudovirus experiment further confirmed the inhibitory effects of IMB 8014 on the S protein mediated entry process. In vitro pharmacokinetic evaluation indicated that the compounds had relatively good drug-likeness properties. Our research suggested that these two compounds have the potential to be further developed as antiviral drugs for COVID-19 treatment.

Prevalence and influencing factors analysis of the polycystic ovary syndrome among female college students in Fuzhou City， Jiangxi Province / 上海预防医学

ObjectiveTo investigate the prevalence of polycystic ovary syndrome （PCOS） among female college students at a university in Fuzhou City， Jiangxi Province， and to facilitate early detection and intervention of PCOS. MethodsUsing a stratified sampling method， a total of 450 female freshmen were randomly selected for PCOS screening. A self-designed questionnaire was used for data collection， covering menstrual status， high androgen signs， lifestyle， dietary habits， and awareness of PCOS. Sample t test and χ2 test were used to compare the basic information and dietary habits between PCOS and non-PCOS cases. The correlation between various indicators and the prevalence of PCOS was analyzed by a logistic regression model. ResultsA total of 12 PCOS cases were identified， with a prevalence rate of 2.99%. PCOS cases exhibited statistically significant differences compared to non-PCOS cases in terms of waist-to-hip ratio， waist circumference， abdominal obesity， the proportion of overweight or obese individuals， and a preference for sweet food （all P<0.05）. Multivariate logistic regression analysis revealed a significant correlation between preference for sweet food and the occurrence of PCOS （OR=4.858， 95%CI=1.199‒19.675，P=0.027）， as well as a significant correlation with PCOS accompanied by abdominal obesity （OR=7.083， 95%CI=0.773‒64.937， P=0.048）. Among the female college students surveyed， 37.90% had never heard of PCOS， 51.62% were only familiar with the name of the disease， and 10.47% had attempted to search for PCOS-related information. ConclusionThe prevalence of PCOS among female college students should not be overlooked and unhealthy dietary habits may be a crucial factor contributing to the occurrence of PCOS during this period. Early screening for PCOS during puberty is crucial.

Prevalence and influencing factors of mild cognitive impairment in the elderly in Songjiang District, Shanghai / 环境与职业医学

Background With the aging of China's population, cognitive impairment in the elderly is receiving increasing public attention. Screening and intervention of people with mild cognitive impairment (MCI) are of great significance to prevent and reduce the occurrence of cognitive impairment. Objective To understand the prevalence and explore potential influencing factors of MCI in the elderly in Songjiang District, Shanghai, and to provide scientific basis for promoting early screening of cognitive impairment and precise intervention of MCI in the elderly in this area. Methods A cross-sectional study design was adopted. From August to October 2022, using multi-stage random sampling, 1800 elderly residents aged 60 years and above were screened for cognitive impairment in 6 neighborhood/village committees in 6 towns in Songjiang District. The survey questionnaires included a sociodemographic questionnaire, a health status and lifestyle questionnaire, the Instrumental Activities of Daily Living (IADL), the Patient Health Questionnaire (PHQ-9), and the Mini-Mental State Examination (MMSE). Prevalence rates of MCI among the elderly by selected social demographic characteristics, health status, and lifestyle were estimated, and potential influencing factors of MCI were evaluated by binary logistic regression. Results A total of 209 elderly residents with MCI and 1591 healthy elderly residents were detected, and the prevalence of MCI in the elderly aged 60 and above was 11.6% in Songjiang District. Being physically active (OR=0.556, 95%CI: 0.399, 0.774) reduced the risk of MCI. Illiteracy (OR=1.810, 95%CI: 1.239, 2.644), primary school education level (OR=3.454, 95%CI: 2.342, 5.092), non-participation in social activities (OR=1.945, 95%CI: 1.360, 2.781), IADL damaged (OR=3.173, 95%CI: 2.137, 4.712), and depression (OR=1.957, 95%CI: 1.112, 3.443) increased the risk of MCI (P＜0.05). Conclusion The prevalence of MCI among the elderly in Songjiang District is lower than the national average. Educational level, physical activity, participation in social activities, IADL, and depression may be the influencing factors of MCI in the elderly. It is recommended to carry out early screening, early detection, and early intervention for cognitive impairment in the elderly. Improving involvement in physical exercise and increasing participation in social activities are encouraged. Special attention should be paid to the needs of vulnerable groups such as low education level and disabled elderly during a community MCI intervention program.
