Hepatitis C virus detection in hospital emergency departments. / Detección de la hepatitis C en los servicios de urgencias hospitalarios.

TEXT: The prevalence of active hepatitis C virus (HCV) infection is higher in hospital emergency departments (EDs) than in the general population. Numerous patients who seek emergency care are unaware that they have detectable viremia, yet they fall outside established ED protocols for HCV screening. Often they belong to groups with difficult access to health care who use the ED as their point of entry to the system. The aim of this consensus paper was to develop an approach to guide ED detection of HCV infection in all Spanish hospitals. Experts from the Spanish Society of Emergency Medicine (SEMES), the Spanish Association for Study of the Liver (AEEH), and the Spanish Society of Infectious Diseases and Clinical Microbiology (SEIMC) met to establish criteria to guide health care professionals' decisions. The experts' review of the literature and discussion in consensus-building meetings resulted in evidence-based recommendations that consider the following aspects: 1) the population to target for HCV screening in the ED, 2) how to inform patients of the process, 3) how to carry out HCV screening, 4) how to order an HCV test, and 5) additional issues such as bundling HCV with other viral tests for comprehensive diagnosis, recording results in medical records, and implementing ways to retain and follow all patients with positive results. This consensus report provides guidelines and tools to facilitate emergency physicians' work and ensure effective detection of HCV infections and subsequent incorporation of patients into the health care system.

TEXTO: La prevalencia de la infección activa por el virus de la hepatitis C (VHC) en los servicios de urgencias hospitalarios (SUH) es superior a la de la población general. Muchos pacientes, desconocedores de su estado de infección y atendidos en urgencias, no cumplen con los criterios establecidos para el cribado del VHC o, muchas veces, son poblaciones de difícil acceso para el sistema sanitario, cuyo único vínculo de entrada son los SUH. Este documento tiene por objetivo elaborar una estrategia que sirva de guía para la detección de VHC en los SUH, de forma que homogenice el abordaje de la infección en todos los hospitales españoles. Un grupo de expertos de la Sociedad Española de Urgencias y Emergencias (SEMES), la Asociación Española para el Estudio del Hígado (AEEH) y la Sociedad Española de Enfermedades Infecciosas y Microbiología Clínica (SEIMC), se reunieron para establecer los criterios que orienten las decisiones de los profesionales sanitarios. Estos se basan en la evidencia científica identificada mediante una revisión bibliográfica, y consensuada en reuniones deliberativas posteriores. Los aspectos abordados son: 1) población diana para la detección del VHC que acude al SUH; 2) información al paciente; 3) realización de la prueba del VHC; 4) solicitud de la prueba del VHC; y 5) otras consideraciones (diagnóstico integral de otras infecciones, registro de la prueba en la historia clínica y estrategias de vinculación y seguimiento). Este consenso proporciona pautas y herramientas para facilitar la labor del urgenciólogo y garantiza la detección efectiva del VHC y la subsiguiente vinculación al sistema sanitario.

Experimental study of specific and nonspecific blood culture bottles for the diagnosis of candidemia.

BACKGROUND: Early diagnosis of candidemia is critical for the correct management and treatment of patients. AIMS: To test the efficacy of different blood culture bottles in the growth of Candida strains. METHODS: We compared the performance of BD BACTEC™ Plus Aerobic/F (Aero) culture bottles with the specific BD BACTEC™ Mycosis IC/F Lytic (Myco) culture bottles using the BD BACTEC™ FX 40 automated blood culture system to determine the mean time-to-detection (TTD) in Candida species. One isolate each of six Candida species was inoculated into blood culture bottles (final concentration, 1-5CFUml-1) and incubated at 37°C until automated growth detection. RESULTS: Candida albicans and Nakaseomyces glabratus (Candida glabrata) were detected earlier in the specific culture bottle, whereas Candida tropicalis was detected earlier in the nonspecific bottle; Candida parapsilosis, Pichia kudriavzevii (Candida krusei), and Meyerozyma guilliermondii (Candida guilliermondii) presented similar TTD in both bottles. CONCLUSIONS: Our study suggests the suitability of using both bottles in clinical laboratories for a faster diagnosis and prompt starting of any treatment.

Integrating adult occurrence and reproduction data to identify conservation measures for amphibians.

Monitoring programs are pivotal to establishing sound management. Due to economic, logistic, and time limitations, monitoring programs often overlook differences among life-history stages. However, species occurrence does not necessarily mean population viability, and it is unclear to what extent monitoring programs that do not consider separately adult presence and reproduction provide effective management indications. Unfortunately, collecting data on certain life stages requires high sampling effort, leading to a trade-off between model reliability and resources needed for monitoring. We collected data on presence and reproduction of amphibians by monitoring 207 waterbodies in Lombardy (northern Italy) in 2017-2022. We then used multistate occupancy models to test whether certain environmental features, namely, pond area, hydroperiod, forest cover, shade, aquatic vegetation, and predators' presence, differentially affected adult occurrence and breeding probabilities of multiple amphibian species. To assess optimal sampling efforts, we modeled the detection probabilities of adults and reproduction across multiple species. Finally, we identified the optimal monitoring strategy under different scenarios of resource availability, comparing adult-only monitoring versus joint assessment of the occurrence of adults and reproduction. In many cases, the main drivers of adult occurrence and reproduction did not coincide because most investigated ecological variables affected one life stage or the other. Forest area, for instance, increased occurrence probabilities of adults of the endemic Rana latastei but showed no effect on their reproduction probabilities. Quantitative estimates of the sampling effort showed that occurrence of adults was easier to spot in 4 out of 7 species. Multicriteria decision analyses showed that when resources were scarce, monitoring adults was the optimal strategy for those 4 species. Conversely, with more resources, monitoring both adults and reproduction emerged as the best strategy for all the considered species. Integrated monitoring of adults and reproduction is essential to comprehensively identify effective conservation measures for amphibians.

Integración de datos de presencia adulta y de reproducción para identificar medidas de conservación para los anfibios Resumen Los programas de monitoreo son fundamentales para establecer una gestión adecuada. Debido a limitaciones económicas, logísticas y de tiempo, los programas de seguimiento suelen pasar por alto las diferencias entre las distintas fases del ciclo de vida. Sin embargo, la presencia de especies no significa necesariamente la viabilidad de la población, y no está claro hasta qué punto los programas de seguimiento que no consideran por separado la presencia de adultos y la reproducción proporcionan indicaciones eficaces para la gestión. Desgraciadamente, la recolección de datos sobre etapas determinadas del ciclo de vida requiere un gran esfuerzo de muestreo, lo que lleva a un compromiso entre la fiabilidad del modelo y los recursos necesarios para el seguimiento. Recopilamos datos sobre la presencia y reproducción de anfibios mediante el monitoreo de 207 cuerpos de agua en Lombardía (norte de Italia) entre 2017 y 2022. Después utilizamos modelos de ocupación multiestado para comprobar si determinadas características ambientales (superficie de los estanques, hidroperiodo, cubierta forestal, sombra, vegetación acuática y presencia de depredadores) afectaban de forma diferencial la presencia de adultos y a las probabilidades de reproducción de múltiples especies de anfibios. Para evaluar los esfuerzos de muestreo óptimos, modelamos las probabilidades de detección de adultos y reproducción de múltiples especies. Por último, identificamos la estrategia de seguimiento óptima en diferentes escenarios de disponibilidad de recursos y comparamos el seguimiento exclusivo de adultos frente a la evaluación conjunta de la presencia de adultos y reproducción. En muchos casos, los principales factores en la presencia de adultos y en la reproducción no coincidían, ya que la mayoría de las variables ecológicas investigadas afectaban a una u otra etapa del ciclo. La cubierta forestal, por ejemplo, aumentó la probabilidad de presencia de adultos de la especie endémica Rana latastei pero no mostraron un efecto sobre su probabilidad de reproducción. Las estimaciones cuantitativas del esfuerzo de muestreo mostraron que la presencia de adultos era más fácil de detectar en cuatro de las siete especies. Los análisis de decisión multicriterio mostraron que, cuando los recursos eran escasos, el seguimiento de los adultos era la estrategia óptima para esas cuatro especies. Por el contrario, con más recursos, el seguimiento tanto de los adultos como de la reproducción resultó ser la mejor estrategia para todas las especies consideradas. El seguimiento integrado de los adultos y la reproducción es esencial para identificar de forma exhaustiva medidas de conservación eficaces para los anfibios.

The Norwegian traumatic grief inventory-self report plus (TGI-SR+): a psychometric evaluation in traumatically bereaved people.

Background: Prolonged grief disorder (PGD) has been added to the ICD-11 and DSM-5-TR. The Traumatic Grief Inventory-Self Report Plus (TGI-SR+) assesses self-rated PGD intensity as defined in ICD-11 and DSM-5-TR. The TGI-SR + is available in multiple languages, but has not been validated yet in Norwegian.Objective: The aim of this study was to evaluate the psychometric properties of the Norwegian TGI-SR + .Method: Bereaved adults (N = 307) whose child or sibling died ≥6 months ago due to a sudden or violent loss completed the TGI-SR + and measures for posttraumatic stress, depression, and precursor PGD symptoms. We examined the factor structure and internal consistency of the ICD-11 and DSM-5-TR PGD items. Convergent validity and known-groups validity was evaluated. Probable PGD cases, pair-wise agreement between diagnostic scoring rules for both PGD criteria-sets, and cut-off scores were calculated.Results: The 1-factor model for ICD-11 and DSM-5-TR PGD showed the best fit and demonstrated good internal consistency. Convergent validity was supported by strong associations between summed ICD-11 and DSM-5-TR PGD scores and summed posttraumatic stress, depression, and precursor prolonged grief scores. Known-groups validity was supported by PGD intensity being related to educational level and time since loss. The perfect pair-wise agreement was reached using the ICD-11 and DSM-5-TR PGD diagnostic scoring rules. The optimal cut-off score for detecting probable PGD cases, when summing all TGI-SR + items, was ≥73.Conclusions: The Norwegian TGI-SR + seems a valid and reliable instrument to assess ICD-11 and DSM-5-TR PGD intensity after losing a child or sibling under traumatic circumstances.

The TGI-SR + is a self-report instrument assessing ICD-11 and DSM-5-TR prolonged grief disorder intensity.The Norwegian TGI-SR + seems to be a valid and reliable instrument to assess prolonged grief disorder intensity.Optimal cut-off for detecting probable prolonged grief disorder cases is ≥73 in this traumatically bereaved sample of parents and siblings.

Delayed diagnosis and missed opportunities in the early detection of atrial fibrillation: a cross-sectional study.

INTRODUCTION: We analysed the frequency of atrial fibrillation (AF) delayed diagnosis and the factors associated with it in newly diagnosed patients. METHODS: This was a descriptive, cross-sectional, multicentre study. Data were collected from newly diagnosed patients with AF through medical records review and interviews during cardiology, internal medicine, primary care and emergency department consultations in Spain. RESULTS: A total of 201 physicians participated in the study (64.2% cardiologists, 21.4% internists). 948 patients (58% men; mean age 72.8 years) were included. In 41.8% of patients, AF was classified as paroxysmal at diagnosis, 30.9% as persistent and 27.3% as permanent. The diagnosis was coincidental in 37%. It was considered that a delayed diagnosis occurred in 49.3% of patients. This delay was associated with the presence of permanent or persistent AF, older age or valvular disease. 74.8% of patients had some contact with the healthcare system in the preceding year. The diagnosis could have been established between 1 and 6 months earlier in 50.7% of cases and more than six months earlier in 20.1%. 54.4% of the patients had experienced AF compatible symptomatology previously. Of these, 32.6% had a consultation without a diagnosis. CONCLUSIONS: In a significant proportion of AF cases, there is a diagnostic delay. Many people with compatible symptoms neither seek consultations nor contact the healthcare system facilities. Consequently, the opportunity for early diagnosis is lost.

Instruments and Warning Signs for Identifying and Evaluating the Frequency of Adverse Events in Intermediate and Long-Term Care Centres: A Narrative Systematic Review.

INTRODUCTION: There is a lack of data about adverse events (AE) in intermediate and long-term care centers (ILCC). We aimed to synthesize the available scientific evidence on instruments used to identify and characterize AEs. We also aimed to describe the most common adverse events in ILCCs. MATERIAL AND METHODS: A narrative systematic review of the literature was conducted according to Prisma recommendations. The PubMed database was searched for articles published between 2000 and 2021. Two reviewers independently screened and reviewed the studies through blind and independent review. We evaluated bias risk with Cochrane's risk of bias tool. Disagreements were resolved by consensus. Discrepancies that were not resolved by discussion were discussed with a third reviewer. Descriptive data was extracted and qualitative content analysis was performed. RESULTS: We found 2191 articles. Based on the inclusion and exclusion criteria, 272 papers were screened by title and abstract, and 66 studies were selected for full review. The instruments used to identify AEs were mostly tools to identify specific AEs or risks of AEs (94%), the remaining 6% were multidimensional. The most frequent categories detected medication-related AEs (n=26, 40%); falls (n=7, 11%); psychiatric AEs (6.9%); malnutrition (4.6%), and infections (4.6%). The studies that used multidimensional tools refer to frailty, dependency, or lack of energy as predictors of AEs. However, they do not take into account the importance of detecting AEs. We found 2-11 adverse drug events (ADE) per resident/month. We found a prevalence of falls (12.5%), delirium (9.6-89%), pain (68%), malnutrition (2-83%), and pressure ulcers (3-30%). Urinary tract infections, lower respiratory tract infections, skin and soft tissue infections, and gastroenteritis were the most common infections in this setting. Transitions between different care settings (from hospitals to ILCC and vice versa) expose AE risk. CONCLUSION: There are many instruments to detect AEs in ILCC, and most have a specific approach. Adverse events affect a significant proportion of patients in ILCC, the nurse-sensitive outcomes, nosocomial infections, and adverse drug events are among the most common. The systematic review was registered with Prospero, ID: CRD42022348168.

Tumor glómico causante de dolor de dedo crónico: la prueba de detección de isquemia es un signo clínico fiable para su diagnóstico. Informe de un caso y revisión de la literatura / Glomus tumor causing chronic finger pain: Ischemia test is a reliable clinical sign for the diagnosis. Case report and review of literature

Los tumores glómicos (TG) son neoplasias benignas raras, que se derivan de la estructura neuroarterial denominada cuerpo glómico, un shunt arteriovenoso especializado implicado en la regulación de la temperatura. Representan menos de 2% de los tumores del tejido blando, y entre 1 y 4,5% de los tumores de la mano. Aun cuando sus primeras descripciones aparecieron hace casi 100 años, son comunes la demora y la ausencia diagnósticas, las cuales originan un sufrimiento terrible. La tríada diagnóstica clásica consiste en dolor espontáneo, sensación de presión y sensibilidad, e hipersensibilidad al frío. La imagen de resonancia magnética (IRM) sigue siendo la modalidad de imagen más útil. La supresión del dolor tras inflar un esfigmomanómetro por encima de los niveles de la presión arterial sistólica (prueba de detección de isquemia) es altamente diagnóstica, por lo que sugerimos el uso rutinario de esta prueba simple en los casos de dolor en la extremidad superior de etiología desconocida. La resección quirúrgica es el tratamiento de elección, y es curativa. (AU)

Glomus tumors are a rare benign neoplasm arising from the neuroarterial structure called the glomus body, a specialized arteriovenous shunt involved in temperature regulation. They represent less than 2% of soft tissue tumors and between 1 and 4.5% of hand's tumors. Even though its first descriptions appeared almost 100 years ago, late and missed diagnoses are common, which leads to terrible suffering. The classic diagnostic triad consists of spontaneous pain, pressure sensation and tenderness, and cold hypersensitivity. Magnetic resonance imaging stills the most useful imaging modality. Abolition of pain after inflating a blood pressure cuff above systolic blood pressure levels (ischemia test) is highly diagnostic, so we suggest the routine use of this simple test in cases of upper limb pain of unknown etiology clear. Surgical excision is the treatment of choice and is curative. (AU)

Intervención educativa para perfeccionar la ejecución del Programa de Detección Precoz del Cáncer Bucal

Introducción: las lesiones premalignas y malignas del complejo bucal se incrementan en la población, lo que demanda una correcta ejecución del Programa de Detección Precoz del Cáncer Bucal (PDCB). En el trabajo se exponen las transformaciones en el nivel de conocimientos de pacientes y estomatólogos acerca de las afecciones concernientes al PDCB para perfeccionar su ejecución. Método: se realizó una intervención educativa en el área de salud Julio Antonio Mella del municipio Camagüey desde mayo de 2022 hasta junio de 2023, con la participación de 36 pacientes y 30 estomatólogos. Las fuentes de información fueron la historia clínica, un cuestionario y una prueba de entrada y salida, aplicados a pacientes y estomatólogos respectivamente, antes y después de la intervención; para constatar las transformaciones. Resultados: antes de la intervención los pacientes estaban mal informados sobre las consecuencias nocivas de hábitos tóxicos, higiénicos y dietéticos, así como desconocimiento de la importancia del correcto autoexamen bucal; los que alcanzaron en su mayoría un alto nivel de conocimientos con la intervención. Los estomatólogos mejoraron sus conocimientos sobre diagnóstico y seguimiento de lesiones pre malignas y malignas del complejo maxilofacial. Discusión: la adecuada ejecución del PDCB descansa tanto en pacientes como en estomatólogos y aunque las investigaciones se enfocan a los primeros por los beneficios reportados; la superación de posgrado constituye una vía para sistematizar conocimientos y fortalecer competencias profesionales que impacten de manera positiva en el PDCB. La intervención educativa se considera satisfactoria al elevar el nivel de conocimientos de pacientes y estomatólogos, lo que demuestra sus potencialidades para perfeccionar la ejecución del PDCB.

Introduction: premalignant and malignant lesions of de oral area increase in the population which demands a correct implementation of the Early Detection of Oral Cancer Program. In this work transformations are exposed knowledge level of both patients and dentists regarding lesions concerning the Early Detection of Oral Cancer Program (EDOCP). Method: educational intervention was carried out in Julio Antonio Mella health area of Camaguey municipality from May 2022 to June 2023 which 36 patients and 30 Deontologists. Information sources were the Clinical History, a questionnaire and a test applied to patients and Deontologists respectively, before and after the intervention, to confirm the transformations in the sample. Results: Prior to intervention patients were poorly informed about consequences of toxic, hygienic and dietetic habits combined with lack of knowledge regarding importance of a correct oral self-examination whose knowledge improved to reach a high level in most of them after the intervention. Deontologists improved their knowledge on diagnosis and follow-up of premalignant and malignant lesions affecting the maxillofacial complex. Discussion: correct application of the EDOCP depends on both patients and deontologists, however reserchers focus on the former due to the reported benefits; the postgraduate training is a way to systematize knowledge and strengthen professional competences with positive impact on EDOCP. The educational intervention was satisfactory since it improved the level of knowledge of both patients and dentists which shows its potential on a correct implementation of the Early Detection of Oral Cancer Program.

Preventive Detection of Driver Drowsiness from EEG Signals using Fuzzy Expert Systems / Detección Preventiva de la Somnolencia del Conductor a partir de Señales EEG Mediante Sistemas Expertos Difusos

Abstract Currently, the percentage of traffic accidents has increased, and according to statistics, this percentage will continue to increase every year, so it is necessary to develop new technologies to prevent this kind of accidents. This paper presents a drowsiness detection system based on electroencephalogram (EEG) signals using a pair of channels (Fp1 and Fp2) applied to drivers before entering their vehicles. First, this model detects the relationship between the area under the curve (AUC) of alpha brain waves, an effective parameter for detecting drowsiness. Then, the extracted information is passed to a fuzzy expert system (FES) that classifies the subject's state as "alert" or "sleepy"; the criterion used was a threshold and training with subjective levels. The proposed system was compared with neural network models, such as support vector machine (SVM), K nearest neighbors (KNN), and random forest (RF). Measurements of one hundred and twenty minutes were performed on each of the ten drivers for two days to test the system. The tests confirm that this system is suitable for preventive measures and that the fuzzy system is superior to traditional neural network methods.

Resumen Actualmente, el porcentaje de accidentes de tráfico ha aumentado, y según las estadísticas, este porcentaje seguirá aumentando cada año, por lo que es necesario desarrollar nuevas tecnologías para prevenir este tipo de accidentes. Este trabajo presenta un sistema de detección de somnolencia basado en señales de electroencefalograma (EEG) utilizando un par de canales (Fp1 y Fp2) aplicado a los conductores antes de entrar en sus vehículos. En primer lugar, este modelo detecta la relación entre el área bajo la curva (AUC) de las ondas cerebrales alfa, un parámetro eficaz para detectar la somnolencia. A continuación, la información extraída se pasa a un sistema experto difuso (FES) que clasifica el estado del sujeto como "alerta" o "somnoliento"; el criterio utilizado fue un umbral y el entrenamiento con niveles subjetivos. El sistema propuesto se comparó con modelos de redes neuronales, como la máquina de vectores de soporte (SVM), K vecinos más cercanos (KNN) y el bosque aleatorio (RF). Se realizaron mediciones de ciento veinte minutos en cada uno de los diez conductores durante dos días para probar el sistema. Las pruebas confirman que este sistema es adecuado para las medidas preventivas y que el sistema difuso es superior a los métodos tradicionales de redes neuronales.

Propiedades Psicométricas de la Escala Conners-3 (SR-S) en Estudiantes Chilenos

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.

Performance on the Latin American version of the Face-Name Associative Memory Exam (LAS-FNAME) distinguishes individuals with Mild Cognitive Impairment from age-matched controls in a sample from Argentina.

INTRODUCTION: The Latin American Spanish version of the Face-Name Associative Memory Exam (LAS-FNAME) has shown promise in identifying cognitive changes in those at risk for Alzheimer's disease (AD). However, its applicability for Mild Cognitive Impairment (MCI) detection in the Latin American population remains unexplored. This study aims to analyze the psychometric properties in terms of validity and reliability and diagnostic performance of the LAS-FNAME for the detection of memory disorders in patients with amnestic MCI (aMCI). MATERIALS AND METHODS: The study included 31 participants with aMCI, diagnosed by a neurologist according to Petersen's criteria, and 19 healthy controls. Inclusion criteria for the aMCI group were to be 60 years of age or older, report cognitive complaints, have a memory test score (Craft Story 21) below a -1.5 z-score and have preserved functioning in activities of daily living. Participants completed LAS-FNAME and a comprehensive neuropsychological assessment. RESULTS: LAS-FNAME showed the ability to discriminate against healthy controls from patients with aMCI (AUC= 75) in comparison with a gold-standard memory test (AUC = 69.1). LAS-FNAME also showed evidence of concurrent and divergent validity with a standard memory test (RAVLT) (r = 0.58, p < .001) and with an attention task (Digit Span) (r = -0.37, p = .06). Finally, the reliability index was very high (α = 0.88). DISCUSSION: LAS-FNAME effectively distinguished aMCI patients from healthy controls, suggesting its potential for detecting early cognitive changes in Alzheimer's prodromal stages among Spanish speakers.

Concordancia inter- e intraobservador del puntaje PI-RADS 2.1 del Colegio Americano de Radiología / Intraobserver and interobserver agreement of the American College of Radiology PI-RADS 2.1 score

Resumen Antecedentes: La resonancia magnética (RM) de próstata es uno de los métodos diagnósticos para la identificación del carcinoma de próstata. La escala PI-RADS (Prostate Imaging and Reporting Data System) es el sistema usado para la interpretación de estas imágenes. Es importante, para su reproducibilidad, la estandarización y la evaluación de dicha escala. Objetivo: Determinar la concordancia inter- e intraobservador de la versión 2.1 del PI-RADS. Material y métodos: Estudio observacional retrospectivo, evaluando 129 RM de pacientes con sospecha de cáncer de próstata por tres radiólogos con diferentes años de experiencia y en dos momentos del tiempo, usando el puntaje PI-RADS 2.1. Se evaluó la concordancia intra- e interobservador. Resultados: La concordancia interobservador fue sustancial (kappa > 0,6) en todos los observadores, siendo la categoría 5 la de mayor acuerdo interobservador. Se observó una alta reproducibilidad intraobservardor, con la mayor kappa siendo de 0,856. Cuando se realizó el análisis según años de experiencia de los radiólogos, la concordancia interobservador fue significativa en todos los casos. Conclusiones: El sistema de clasificación PI-RADS 2.1 es reproducible para las diferentes categorías y aumenta la concordancia cuando se trata de lesiones con mayor probabilidad de cáncer clínicamente significativo.

Abstract Background: Magnetic Resonance Imaging (MRI) of the prostate is a key diagnostic tool for identifying prostate carcinoma. The Prostate Imaging-Reporting and Data System (PI-RADS) scale is the standard system for interpreting these images. Standardizing and evaluating this scale is crucial for ensuring consistent and reproducible results. Objective: This study aims to assess both the interobserver and intraobserver agreement of the PI-RADS version 2.1. Material and methods: In this retrospective observational study, 129 prostate MRI scans from patients with suspected prostate cancer were evaluated. Three radiologists, each with different levels of experience, analyzed these scans at two separate times using the PI-RADS 2.1 scoring system. Both intraobserver and interobserver agreements were measured. Results: The study found substantial interobserver agreement (kappa > 0.6) across all categories, with category 5 showing the highest level of agreement. Intraobserver reproducibility was also high, with the highest kappa value reaching 0.856. Further analysis based on the radiologists’ years of experience revealed significant interobserver agreement in all instances. Conclusions: The PI-RADS 2.1 classification system demonstrates high reproducibility across different categories, particularly for lesions more likely to be clinically significant cancers. This underscores its reliability in varied diagnostic scenarios.

Estandarización de requerimientos mínimos para la formación de centro de detección temprana de cáncer de pulmón en América Latina / Standardization of Minimum Requirements for the Formation of an Early Detection Center for Lung Cancer in Latin America

Introducción: El cáncer de pulmón (CP) es una enfermedad con gran impacto a nivel mundial en el número de muertes y en costos en salud. La alta incidencia y mortalidad de esta enfermedad asociada al diagnóstico tardío, y la mejoría del pronóstico ante una detección temprana, determinan que sea una patología pasible de beneficiarse mediante detección temprana. La tomografía de baja dosis de radiación (TCBD) demostró ser un método que se pue- de realizar periódicamente a un grupo de personas con alto riesgo de desarrollar CP y así reducir la mortalidad por esta enfermedad. Sin embargo, este beneficio es tal cuan- do se encuentra desarrollado bajo un programa organizado y con participación multi- disciplinaria especializada en cáncer de pulmón. Métodos: Se plantea determinar lineamientos básicos para el desarrollo de la detección temprana de cáncer de pulmón en América Latina para que pueda ser realizada en forma uniforme, con el menor riesgo y el máximo beneficio esperado. Se analizaron las principales publicaciones referidas a este tema, contemplando la diversidad de atención y acceso de América Latina. Resultado: Se desarrollan requerimientos mínimos para la implementación de un pro- grama. Discusión: El número de programas en la región es escaso y depende más de esfuerzos individuales que de políticas generales de salud. Consideramos que estos lineamien- tos pueden servir de apoyo para el desarrollo de más programas en la región y de for- ma más homogénea.

Introduction: Lung cancer (LC) is a disease with a great impact worldwide in the number of deaths and health costs. The high incidence and mortality of this disease associated with late diagnosis and the improved prognosis with early detection determine that it is a pathology that can benefit from early detection. Low radiation dose tomography (LDCT) demonstrated a method that can be performed periodically to a group of people at high risk of developing CP and thus reduce mortality from this disease. However, this benefit is such when it is developed under an organized program with multidisciplinary participation specialized in lung cancer. Methods: It is proposed to determine basic guidelines for the development of early de- tection of lung cancer in Latin America so that it can be carried out uniformly, with the lowest risk and the maximum expected benefit. The main publications referring to this topic were analyzed, considering the diversity of care and access in Latin America. Result: Minimum requirements are developed for the implementation of a program. Discussion: The number of programs in the region is small and depends more on individual efforts than on general health policies. We consider that these guidelines can serve as support for the development of more programs in the region and in a more ho- mogeneous way.

Early nutritional risk detection and intervention in COVID-19 hospitalized patients through the implementation of electronic automatized alarms.

INTRODUCTION: Hospitalized COVID-19 patients may present acute malnutrition which could influence morbidity and mortality. In the first wave of the pandemic severe weight loss was observed in many hospitalized patients. This pilot study evaluates the usefulness of an electronic automatized alarm for the early quantification of a low food intake as a predictor of the risk of malnutrition using COVID-19 disease as a model of severe illness. METHODS: Observational prospective nutritional screening with a daily automatized warning message to the Endocrinology and Nutrition Service provided by the Information Systems. All adult patients admitted for COVID-19 from November 2020 to February 2021 were included. When diet intake was <50% during consecutive 48h, an automated message was generated identifying the patient as "at nutritional risk (NR)" and additional specialist nutritional evaluation and therapy was performed within the next 24h. RESULTS: 205 patients out of 1176 (17.4%) were detected by automatized alarm and were considered as presenting high NR; 100% were concordant by the validated nutritional screening SNAQ. Nutritional support after detection was: 77.6% dietary adaptation+oral supplements; 9.3% enteral nutrition (EN); 1.5% parenteral nutrition (PN); 1% EN+PN and 10.7% no intervention is performed due to an end-of-life situation. Median weight loss during admission was 2.5kg (p25 0.25-p75: 6kg). Global mortality was 6.7% while in those detected by automatized alarm was 31.5%. CONCLUSIONS: The implementation of an electronic NR screening tool was feasible and allowed the early nutritional assessment and intervention in COVID-19 hospitalized patients and can be useful in patients hospitalized for other pathologies.

Management of colorectal cancer screening backlog due to the COVID-19 pandemic: A retrospective analysis of the use of a colorectal cancer screening clinical-decision support tool in Argentina

Background The COVID-19 pandemic created a backlog in colorectal cancer (CRC) screening and surveillance colonoscopies. The real impact in Argentina is not fully known. Goal To estimate the impact of the COVID-19 pandemic on CRC prevention by comparing the number of CRC screening and surveillance consults in a clinical decision support-tool used in Argentina before, during and after pandemic lockdown. Methods We analyzed data from May 2019 to December 2021 from CaPtyVa, a clinical decision support tool for CRC screening and surveillance. Queries were divided in pre-pandemic (May 2019 to March 2020), lockdown (April 2020 to December 2020), and post-lockdown (January 2021 to December 2021). The number of CRC monthly screening and surveillance visits were compared among the three periods and stratified according to CRC risk. Results Overall, 27,563 consults were analyzed of which 9035 were screening and 18,528 were surveillance. Pre-pandemic, the median number of screening consults was 346 per month (IQR25–75 280–410). There was a decrease to 156 (80–210)/month (p < 0.005) during lockdown that partially recovered during post-lockdown to 230 (170–290)/month (p = 0.05). Pre-pandemic, the median number of surveillance consults was 716 (560–880)/month. They decreased to 354 (190–470)/month during lockdown (p < .05) and unlike screening, completely recovered during post-lockdown to 581 (450–790)/month. Conclusions There was a >50% decrease in the number of CRC screening and surveillance consults registered in CaPtyVa during lockdown in Argentina. Post-lockdown, surveillance consults recovered to pre-pandemic levels, but screening consults remained at 66% of pre-pandemic levels. This has implications for delays in CRC diagnoses and patient outcomes (AU)

Antecedentes La pandemia de COVID-19 provocó atraso en las colonoscopias de detección y vigilancia del cáncer colorrectal (CCR). Objetivo Estimar el impacto de la pandemia de COVID-19 en la prevención del CCR comparando el número de consultas de pesquisa y vigilancia del CCR en una herramienta digital de apoyo a la decisión clínica utilizada en Argentina antes, durante y después del confinamiento. Métodos Analizamos datos entre mayo 2019 a diciembre 2021 de CaPtyVa, una herramienta digital de apoyo a la toma de decisiones clínicas para la pesquisa y vigilancia del CCR. Las consultas se dividieron en prepandemia (mayo 2019- marzo 2020), confinamiento (abril 2020- diciembre 2020) y post-confinamiento (enero 2021-diciembre 2021). El número de visitas mensuales de pesquisa y vigilancia de CCR se comparó entre períodos y se estratificó según riesgo de CCR. Resultados Prepandemia, la mediana de consultas de detección fue 346 mes (IQR25-75 280-410). Hubo una disminución a 156 (80-210)/mes (p<0,005) durante el confinamiento que ascendió a 230 (170-290)/mes (p=0,05) en el post-confinamiento. Prepandemia, la mediana de consultas de vigilancia fue 716 (560-880)/mes. Disminuyeron a 354 (190-470)/mes durante el confinamiento (p<0,05) y se recuperaron por completo durante el post-confinamiento. Conclusiones Hubo una disminución >50% en el número de consultas de detección y vigilancia de CCR registradas en CaPtyVa durante el confinamiento en Argentina. Post-confinamiento, las consultas de vigilancia se recuperaron a niveles prepandemia, pero las consultas de detección se mantuvieron en el 66 % de niveles históricos. Esto tendría implicaciones en los diagnósticos y pronósticos de CCR (AU)

Glomus tumor causing chronic finger pain: ischemia test is a reliable clinical sign for the diagnosis. Case report and review of literature.

Glomus tumors are a rare, benign neoplasm arising from the neuroarterial structure known as the glomus body, which is a specialized arteriovenous shunt involved in temperature regulation. They account for less than 2% of soft tissue tumors and between 1% and 4.5% of tumors in the hand.. Despite their first descriptions appearing almost 100 years ago, late and missed diagnoses are common, leading to significant suffering. The classic diagnostic triad includes spontaneous pain, a sensation of pressure and tenderness, and cold hypersensitivity. Magnetic resonance imaging remains the most useful imaging modality. The abolition of pain after inflating a blood pressure cuff above the systolic blood pressure level (ischemia test) is highly diagnostic.Therefore, we suggest the routine use of this simple test in cases of upper limb pain of unclear etiology . Surgical excision is the treatment of choice and is curative.

Chilean consensus by expert panel using the Delphi technique for primary and secondary prevention of gastric cancer. / Estrategias para la prevención primaria y secundaria del cáncer gástrico: consenso chileno de panel de expertos con técnica Delfi.

INTRODUCTION: Gastric cancer (GC) is the first cause of cancer-related death in Chile and 6th in Latin America and the Caribbean (LAC). Helicobacter pylori (H. pylori) is the main gastric carcinogen, and its treatment reduces GC incidence and mortality. Esophageal-gastro-duodenoscopy (EGD) allows for the detection of premalignant conditions and early-stage GC. Mass screening programs for H. pylori infection and screening for premalignant conditions and early-stage GC are not currently implemented in LAC. The aim of this study is to establish recommendations for primary and secondary prevention of GC in asymptomatic standard-risk populations in Chile. METHODS: Two on-line synchronous workshops and a seminar were conducted with Chilean experts. A Delphi panel consensus was conducted over 2 rounds to achieve>80% agreement on proposed primary and secondary prevention strategies for the population stratified by age groups. RESULTS: 10, 12, and 12 experts participated in two workshops and a seminar, respectively. In the Delphi panel, 25 out of 37 experts (77.14%) and 28 out of 52 experts (53.85%) responded. For the population aged 16-34, there was no consensus on non-invasive testing and treatment for H. pylori, and the use of EGD was excluded. For the 35-44 age group, non-invasive testing and treatment for H. pylori is recommended, followed by subsequent test-of-cure using non-invasive tests (stool antigen test or urea breath test). In the ≥45 age group, a combined strategy is recommended, involving H. pylori testing and treatment plus non-invasive biomarkers (H. pylori IgG serology and serum pepsinogens I and II); subsequently, a selected group of subjects will undergo EGD with gastric biopsies (Sydney Protocol), which will be used to stratify surveillance according to the classification Operative Link for Gastritis Assessment (OLGA); every 3 years for OLGA III-IV and every 5 years for OLGA I-II. CONCLUSION: A "test-and-treat" strategy for H. pylori infection based on non-invasive studies (primary prevention) is proposed in the 35-44 age group, and a combined strategy (serology and EGD) is recommended for the ≥45 age group (primary and secondary prevention). These strategies are potentially applicable to other countries in LAC.

Missed opportunities for HIV diagnosis among incarcerated people in the Federal District, Brasilia, Brazil

Objective. Evaluate the pattern of contact with the healthcare system, including prison health facilities, and HIV testing. Method. This was a quantitative case-control study of HIV infected and uninfected incarcerated people serving time in 2019 in the Federal District, matched by age. Results. There was no difference in the pattern of contact with the healthcare system or the pattern of testing between HIV-infected and uninfected incarcerated people. Most of the infected patients were diagnosed in the prison environment and had early infections, demonstrating the effectiveness of screening in this scenario. Conclusion: The pattern of contact with the healthcare system among the individuals in this study probably reflects that of young men in general, i.e., less contact with primary care outpatient services and trauma as the main reason for contact in emergency departments. 

Objetivo. Evaluar el patrón de contacto con el sistema sanitario, incluidos los centros sanitarios penitenciarios, y las pruebas del VIH. Método. Estudio cuantitativo de casos y controles de personas infectadas y no infectadas por el VIH que cumplían condena en 2019 en el Distrito Federal, emparejadas por edad. Resultados. No hubo diferencias en el patrón de contacto con el sistema de salud ni en el patrón de realización de pruebas entre personas encarceladas infectadas y no infectadas por VIH. La mayoría de los pacientes infectados fueron diagnosticados en el medio penitenciario y presentaron infecciones precoces, lo que demuestra la eficacia del cribado en este escenario. Conclusiones. El patrón de contacto con el sistema sanitario entre los individuos de este estudio probablemente refleja el de los hombres jóvenes en general, es decir, menor contacto con los servicios ambulatorios de atención primaria y traumatismos como principal motivo de contacto en los servicios de urgencias. 

Objetivo. O estudo avaliou o padrão de contato com o sistema de saúde e de testagem para HIV, incluindo as unidades de saúde prisionais.  Métodos. Trata-se de estudo quantitativo de caso-controle em detentos que cumpriam pena em 2019 no Distrito Federal, pareados por idade. Resultados. Não houve diferença no padrão de contato com o sistema de saúde e padrão de oferta de testagem entre detentos infectados ou não com HIV. A maior parte dos infectados teve o diagnóstico realizado no ambiente prisional e de maneira precoce, evidenciando efetividade do rastreamento nesse cenário. Conclusão. O padrão de contato com o sistema de saúde dos indivíduos neste estudo reflete provavelmente o de homens jovens como um todo: pouco contato com serviços ambulatoriais de atenção primária e trauma como principal motivo de contato, em prontos-socorros.  

Exposing Suspects to Their Sketches in Repeated Interviews to Elicit Information and Veracity Cues / Exponiendo en entrevistas repetidas a los sospechosos a sus esquemas para obtener información e indicios de veracidad

Background/Aim: has shown that sketching while narrating facilitates the elicitation of information and verbal veracity cues in single interviews. We examined if these effects are retained when suspects are shown their sketch after one week in a repeated interview. Method: Participants (N = 173) completed a mock mission and then told the truth or lied about it in an immediate interview (interview 1). Participants either verbally reported the mission (Free recall condition) or sketched it while describing what they were sketching (sketch condition). After one week, all participants were asked for a free recall without sketching (interview 2). Half of the participants in the Sketch condition had access to their sketch while they verbally reported the event whereas the remaining half did not access the sketch. Results: Truth tellers provided more information than lie tellers in both interviews, and sketching elicited more information than a free recall but only in Interview 1. Participants who had access to their sketch in interview 2 repeated more information than those who did not have access, but accessing the sketch did not have an effect on veracity cues. Conclusions: Thus, sketching enhanced the elicitation of information in Interview 1 and access to the sketch in interview 2 seemed helpful for recalling previously reported information. (AU)

Antecedentes/objetivo: La investigación ha revelado que el uso de esquemas mientras se lleva a cabo una narración facilita la obtención de información y de indicios verbales de veracidad en una entrevista. Analizamos si estos efectos se mantienen cuando se somete a los sospechosos a su esquema de los hechos en entrevistas repetidas (una semana después). Método: Los participantes (N = 173) completaron una misión simulada y luego contaban la verdad o mentían sobre la misma en una entrevista realizada de modo inmediato (entrevista 1). Los participantes o bien referían verbalmente la misión (condición de recuerdo libre) o la esquematizaban (condición de esquematización). Después de una semana se pidió a todos los participantes un recuerdo libre sin esquematizar (entrevista 2). La mitad de los participantes de la condición de esquematización podían acceder a su esquema mientras referían verbalmente el suceso y la otra mitad no tenía acceso al esquema. Resultados: Los que contaban la verdad daban más información que los que mentían en ambas entrevistas y el esquema facilitaba más información que el recuerdo libre aunque tan solo en la entrevista 1. Aquellos participantes que tenían acceso a su esquema en la entrevista 2 repetían más información que quienes no tenían acceso, aunque el acceso no tenía efecto alguno en indicios de veracidad. Conclusiones: En conclusión, los esquemas incrementaron la obtención de información en la entrevista 1 y el acceso al esquema en la entrevista 2 resultó útil para recordar la información relatada previamente.

[The necessary response of health services to gender violence. Comprehensive care and provision of integrated services]. / La respuesta necesaria de los servicios de salud ante la violencia de género. Atención integral y prestación de servicios integrados.

Gender violence has multiple and serious consequences for the health of victims and their families, hence the reason for the important role that the health system plays in addressing it. Health professionals have a key role in the response, which must include early detection, care, and follow-up; actions in which primary care, because of its privileged position in the system, can play a fundamental part. This article establishes the necessary characteristics for the intervention to be effective: comprehensive care, multidisciplinary approach, intersectoral coordination, and integrated service provision; all of it community-oriented, person-centered, and adapted to its context (social factors and vulnerabilities) with an intersectional approach. The woman, her sons and daughters, and other cohabitants, as well as the perpetrator, are considered the object of intervention in the response, and specific guidelines for action are provided for detection, care, and follow-up. Reorientation of interventions, with emphasis on a community approach, is also proposed.
