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.

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)

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.

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.

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.

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.  

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.

[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.

Cancer screening in people with HIV: Implementation in clinical practice and barriers perceived by medical specialists in Spain.

OBJECTIVE: To assess the degree of implementation of cancer screening recommendations in people living with HIV (PLHIV) in Spain. METHODS: A self-administered questionnaire was designed on the strategies used for early detection of the main types of cancer in PLHIV. The survey was distributed electronically to HIV physicians participating in the Spanish CoRIS cohort. RESULTS: 106 questionnaires were received from 12 different Spanish Autonomous Communities, with an overall response rate among those who accessed the questionnaire of 60.2%. The majority responded that they followed the CPGs recommendations for the early detection of liver (94.3%), cervical (93.2%) and breast (85.8%) cancers. In colorectal and anal cancer, the proportion was 68.9% and 63.2%, and in prostate and lung cancer of 46.2% and 19.8%, respectively. In hospitals with a greater number of beds, a tendency to perform more cancer screening and greater participation of the Infectious Diseases/HIV Services in the screening programmes was observed. Significant differences were observed in the frequency of colorectal and anal cancer screening among the different Autonomous Communities. The most frequent reasons for not performing screening were the scarcity of material and/or human resources and not being aware of what is recommended in the CPGs. CONCLUSIONS: There are barriers and opportunities to expand cancer screening programmes in PLHIV, especially in colorectal, anal and lung cancers. It is necessary to allocate resources for the early detection of cancer in PLHIV, but also to disseminate CPGs screening recommendations among medical specialists.

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.

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.

Adequação da oferta de procedimentos para a detecção precoce do câncer de mama no Sistema Único de Saúde: um estudo transversal, Brasil e regiões, 2019 / Adequacy of provision of procedures for early detection of breast cancer in the Brazilian Unified National Health System: a cross-sectional study conducted in Brazil and its regions, 2019 / Adecuación de la oferta de procedimientos para la detección precoz del cáncer de mama en el Sistema Único de Salud: un estudio transversal, Brasil y regiones, 2019

Resumo: A detecção precoce é uma das estratégias para o controle do câncer de mama e, para tanto, é fundamental garantir o acesso à investigação dos casos suspeitos para continuidade do cuidado e tratamento oportuno. Este estudo tem por objetivo estimar a necessidade de procedimentos para detecção precoce dessa neoplasia e avaliar a sua adequação no atendimento às mulheres rastreadas e sintomáticas no Sistema Único de Saúde (SUS), no ano de 2019. Foi realizado um estudo descritivo transversal para analisar a oferta de exames de detecção precoce do câncer de mama, comparando a necessidade estimada com os procedimentos realizados no SUS. Foram utilizados os parâmetros disponibilizados pelo Instituto Nacional de Câncer para estimar a população e a necessidade de exames para a detecção precoce. No Sistema de Informações Ambulatoriais do SUS, obteve-se o número de procedimentos realizados em 2019. Observou-se um déficit de mamografias de rastreamento no país (-45,1%), variando entre -31,4% na Região Sul a -70,5% na Região Norte. Se a oferta desse exame fosse direcionada para a população-alvo do rastreamento, o déficit no país reduziria para -14,8% e haveria sobreoferta no Sul (6,2%). Os procedimentos de investigação diagnóstica apresentaram variações entre as regiões, com maiores déficits de punção por agulha grossa (-90,8%) e biópsia/exérese de nódulo da mama (-80,6%) observados no Centro-oeste, e o maior déficit de exames anatomopatológicos no Norte (-88,5%). A comparação entre a produção e a necessidade de procedimentos para detecção precoce do câncer de mama no Brasil identificou déficits e inadequações que devem ser melhor conhecidos e equacionados em nível estadual e municipal.

Abstract: Early detection is a major strategy in breast cancer control and, for this reason, it is important to ensure access to investigation of suspected cases for care continuity and timely treatment. This study aimed to estimate the need for procedures of breast cancer early detection and assess their adequacy for providing care to screened and symptomatic women in the Brazilian Unified National Health System (SUS) in 2019. A descriptive cross-sectional study was conducted to analyze the provision of tests for breast cancer early detection, comparing the estimated need with the procedures performed in the SUS. Parameters provided by the Brazilian National Cancer Institute were used to estimate the population and the need for early detection tests. The number of procedures performed in 2019 was obtained from the Outpatient Information System of the SUS. A deficit in screening mammograms was observed in the country (-45.1%), ranging from -31.4% in the South Region to -70.5 % in the North Region. If this test was offered to the target population, the deficit in the country would reduce to -14.8% and there would be an oversupply in the South Region (6.2%). Diagnostic investigation procedures varied between the regions, with higher deficits in coarse needle biopsy (-90.8%) and breast lump biopsy/excision (-80.6%) observed in the Central-West Region, and the highest deficit in anatomopathological exams in the North Region (-88.5%). The comparison between the production and need for procedures of breast cancer early detection in Brazil and its regions identified deficits and inadequacies that must be better understood and addressed at the state and municipal levels.

Resumen: La detección temprana es una de las estrategias para el control del cáncer de mama y, para ello, es fundamental garantizar el acceso a la investigación de los casos sospechosos para la continuidad del cuidado y el tratamiento oportuno. El presente estudio tiene como objetivo estimar la necesidad de procedimientos para la detección temprana de esta neoplasia y evaluar su adecuación en la atención a las mujeres rastreadas y sintomáticas en el Sistema Único de Salud (SUS) brasileño, en el año 2019. Se realizó un estudio descriptivo transversal para analizar la oferta de pruebas para la detección temprana del cáncer de mama, comparando la necesidad estimada con los procedimientos realizados en el SUS. Se utilizaron los parámetros proporcionados por el Instituto Nacional del Cáncer para estimar la población y la necesidad de pruebas para la detección temprana. El número de procedimientos realizados en el 2019 se obtuvo del Sistema de Información Ambulatoria del SUS. Se observó un déficit de mamografías de tamizaje en el país (-45,1%), oscilando entre el -31,4% en la Región Sur y el -70,5% en la Región Norte. Si la oferta de esta prueba se dirigiera a la población objetivo del rastreo, el déficit en el país se reduciría al -14,8% y habría una sobreoferta en el Sur (6,2%). Los procedimientos de investigación diagnóstica presentaron variaciones entre regiones, observándose mayores déficits en punción con aguja gruesa (-90,8%) y biopsia/escisión de nódulo mamario (-80,6%) en el Centro-Oeste, y el mayor déficit de pruebas anatomopatológicas en el Norte (-88,5%). La comparación entre la producción y la necesidad de procedimientos para la detección temprana del cáncer de mama en Brasil y en las regiones identificó déficits e insuficiencias que deben ser mejor conocidos y abordados a nivel estatal y municipal.

Clinical features of psittacosis in 46 Chinese patients / Características clínicas de 46 pacientes con psittacitis China

Background: Psittacosis is a relatively uncommon cause of community-acquired pneumonia, often leading to diagnostic difficulty.Methods: A retrospective study was conducted on the clinical features of psittacosis patients in China. Forty-six cases of Chlamydophila psittaci infection with atypical pneumonia of varying severity in the last two years were described retrospectively.Results: Fever, relative bradycardia, and other systemic upsets were the main clinical presentation. The most common radiographic abnormality was segmental or lobar shadowing or consolidation. The total white cell counts were usually normal or slightly increased. The concentration of creatine kinase, C reactive protein, and lactic dehydrogenase increased, while albumin decreased remarkably. These cases exhibited good recovery after being treated with tetracycline or quinolone antibiotics.Conclusion: These features may help differentiate psittacosis from other traditional bacterial pneumonia. However, they do not provide a definitive diagnosis. Psittacosis diagnosis must perform the whole-genome sequencing for Chlamydophila psittaci in respiratory, blood, or sputum specimens. Increased awareness of psittacosis can shorten diagnostic delays and improve patient outcomes.(AU)

Antecedentes: La psitacosis es una causa relativamente poco común de neumonía adquirida en la comunidad, y a menudo conduce a dificultades diagnósticas.Métodos: Se realizó un estudio retrospectivo sobre las características clínicas de los pacientes con psitacosis en China, en el que se describen retrospectivamente 46 casos de infección por Chlamydia psittaci con neumonía atípica de gravedad variable en los últimos dos años.Resultados: La fiebre, la bradicardia relativa y otros trastornos sistémicos fueron la presentación clínica principal. La anomalía radiográfica más común fue el sombreado o consolidación segmentaria o lobular. Los recuentos totales de glóbulos blancos fueron generalmente normales o ligeramente aumentados. Las concentraciones de creatina quinasa, proteína C reactiva y deshidrogenasa láctica aumentaron, mientras que la albúmina disminuyó notablemente. Estos casos mostraron una buena recuperación después de ser tratados con antibióticos de tetraciclina o quinolona.Conclusión: Estas características pueden ayudar a diferenciar la psitacosis de otras neumonías bacterianas tradicionales. Sin embargo, no proporcionan un diagnóstico definitivo. El diagnóstico de psitacosis debe realizar la secuenciación del genoma completo de Chlamydia psittaci en muestras respiratorias, sanguíneas o de esputo. Una mayor conciencia de la psitacosis puede acortar los retrasos en el diagnóstico y mejorar los resultados de los pacientes.(AU)

Detección molecular de patógenos en deposiciones en niños consultantes por diarrea aguda en Servicios de Urgencia / Molecular detection of pathogens in stool samples of children consulting for acute diarrhea in emergency services

INTRODUCCIÓN: La diarrea aguda continúa siendo una de las principales causas de morbilidad en niños; sin embargo, el diagnóstico etiológico presenta limitaciones dada la baja sensibilidad de los métodos tradicionales. OBJETIVO: Describir los microorganismos identificados en niños que acudieron al Servicio de Urgencia (SU) de un hospital universitario en Santiago, Chile, por diarrea aguda y a los que se le solicitó panel molecular gastrointestinal. MÉTODOS: Se revisaron fichas clínicas y resultados de panel gastrointestinal realizados entre junio de 2017 y marzo de 2020. RESULTADOS: Se incluyeron 198 pacientes, edad promedio de 54,5 meses y 60,6% (120/198) de sexo masculino. La positividad del panel fue de 78,8% (156/198) con 35,3% (55/156) de las muestras polimicrobianas. Se identificaron 229 microorganismos, de los cuales 72,9% (167/229) corresponden a bacterias, 25,8% (59/229) a virus y 1,3% (3/229) a parásitos. Destacaron Campylobacter spp. y Escherichia coli enteropatógena (ECEP) como las bacterias más frecuentemente identificadas. Los pacientes con detección de Campylobacter spp. presentaron con mayor frecuencia fiebre (p = 0,00). ECEP se aisló principalmente (82,5%) en muestras polimicrobianas. DISCUSIÓN: Los resultados enfatizan el potencial que poseen los estudios moleculares para mejorar el diagnóstico etiológico de la diarrea, pero a la vez llevan a cuestionar el rol patogénico de algunos microorganismos identificados.

BACKGROUND: Acute diarrhea continues to be one of the main causes of morbidity in children, however the etiologica diagnosis presents limitations given the low sensitivity of traditional methods. AIM: To describe the microorganisms identified in children who attended the emergency department (ED) in Santiago, Chile, due to acute diarrhea and to whom a gastrointestinal panel was requested as part of their study. MATERIAL AND METHODS: Clinical records and results of the gastrointestinal panel carried out between June 2017 and March 2020 were reviewed. RESULTS: 198 patients were included, the average age was 54.5 months and 60.6% (120/198) were males. Positivity was 78.8% (156/198) with 35.3% (55/156) of the samples being polymicrobial. 229 microorganisms were identified, of which 72.9% (167/229) corresponded to bacteria, 25.8% (59/229) to viruses, and 1.3% (3/229) to parasites. Campylobacter spp. and enteropathogenic Escherichia coli (EPEC) were the most frequently identified bacteria. Patients with detection of Campylobacter spp. presented a higher frequency of fever (p = 0.00). EPEC was isolated in 82.5% of the cases in polymicrobial samples. DISCUSSION: The results emphasize the potential of molecular studies to improve the etiological diagnosis of diarrhea and at the same time lead to question the pathogenic role of some microorganisms.

Molecular detection of SARS-CoV-2 in Argentina: Evaluation of alternative diagnostic tools for the decentralization of the diagnosis

Abstract The rocketing number of COVID-19 cases highlighted the critical role that diagnostic tests play in medical and public health decision-making to contain and mitigate the SARS-CoV-2 pandemic. This study reports the evaluation and implementation of different tests for the molecular detection of SARS-CoV-2 in the central region of Argentina. We evaluated 3 real time RT-PCR kits (GeneFinder COVID-19 Plus RealAmp Kit, DisCoVery SARS-CoV-2 RT-PCR Detection Kit and WGene SARS-CoV-2 RT Detection), 2 nucleic acid extraction methods [MagaBio plus Virus DNA/RNA Purification Kit II (BioFlux), 35-min vs. 9-min, a pre-analytical reagent (FlashPrep®) and 2 isothermal amplification tests (Neokit Plus and ELA CHEMSTRIP®). The order according to the best performance of the 3 real-time RT-PCR kits evaluated was: DisCoVery > GeneFinderTM> WGene. The 2 RNA extraction methods showed similar good results: MagaBio plus Virus RNA Purification Kit II (BioFlux) 9-min was selected due to its faster performance. FlashPrep® reagent showed excellent results to perform direct RNA detection. Isothermal amplification assays showed acceptable sensitivity and specificity values (>80%), except in samples with Ct> 30. Our data show optimal real time RT-PCR kits and alternative molecular methods for SARS-CoV-2 diagnostic. These alternative assays proved to be aceptable.

Resumen La explosión de casos de COVID-19 resaltó el papel fundamental que desempeñan las pruebas de diagnóstico en la toma de decisiones médicas y de salud pública para contener y mitigar la pandemia de SARS-CoV-2. Este estudio reporta la evaluación y la implementación de diferentes test para la detección molecular de SARS-CoV-2 en la región central de Argentina. Evaluamos tres kits de RT-PCR en tiempo real (GeneFinder COVID-19 Plus RealAmp Kit, DisCoVery SARS-CoV-2 RT-PCR Detection Kit y WGene SARS-CoV-2 RT Detection), dos métodos de extracción de ácidos nucleicos (MagaBio plus Virus DNA/RNA Purification Kit II [BioFlux, 35-min vs. 9-min), un reactivo pre-analítico (FlashPrep®) y dos test de amplificación isotérmica (Neokit Plus and ELA CHEMSTRIP®). El orden de rendimiento de los tres kits de RT-PCR en tiempo real evaluados fue el siguiente: DisCoVery GeneFinder™ WGene. Los dos métodos de extracción de RNA mostraron buenos y similares resultados; se seleccionó MagaBio plus Virus RNA Purification Kit II (BioFlux) 9-min debido a su rápido tiempo de procesamiento. El reactivo FlashPrep® mostró excelentes resultados para realizar detección directa de RNA. Los ensayos de amplificación isotérmica mostraron valores de sensibilidad y de especificidad aceptables (80%), excepto en muestras con Ct 30. Nuestros resultados muestran kits de RT-PCR en tiempo real óptimos, como así también métodos moleculares alternativos para el diagnóstico de SARS-CoV-2 que resultan aceptables para su uso en contextos adversos, de descentralización y en diferentes escenarios epidemiológicos, para la detección rápida y precisa del SARS-CoV-2.
