Quadruple therapies show a higher eradication rate compared to standard triple therapy for Helicobacter pylori infection within the LEGACy consortium. A multicenter observational study in European and Latin American countries.

INTRODUCTION: Gastric cancer (GC) is one of the most lethal malignancies worldwide. Helicobacter pylori is the primary cause of GC; therefore, its eradication reduces the risk of developing this neoplasia. There is extensive evidence regarding quadruple therapy with relevance to the European population. However, in Latin America, data are scarce. Furthermore, there is limited information about the eradication rates achieved by antibiotic schemes in European and Latin American populations. OBJECTIVE: To compare the effectiveness of standard triple therapy (STT), quadruple concomitant therapy (QCT), and bismuth quadruple therapy (QBT) in six centers in Europe and Latin America. METHODS: A retrospective study was carried out based on the LEGACy registry from 2017 to 2022. Data from adult patients recruited in Portugal, Spain, Chile, Mexico, and Paraguay with confirmed H. pylori infection who received eradication therapy and confirmatory tests at least 1 month apart were included. Treatment success by each scheme was compared using a mixed multilevel Poisson regression, adjusting for patient sex and age, together with country-specific variables, including prevalence of H. pylori antibiotic resistance (clarithromycin, metronidazole, and amoxicillin), and CYP2C19 polymorphisms. RESULTS: 772 patients were incorporated (64.64% females; mean age of 52.93 years). The total H. pylori eradication rates were 75.20% (255/339) with STT, 88.70% (159/178) with QCT, and 91.30% (191/209) with QBT. Both quadruple therapies (QCT-QBT) showed significantly higher eradication rates compared with STT, with an adjusted incidence risk ratio (IRR) of 1.25 (p: <0.05); and 1.24 (p: <0.05), respectively. The antibiotic-resistance prevalence by country, but not the prevalence of CYP2C19 polymorphism, showed a statistically significant impact on eradication success. CONCLUSIONS: Both QCT and QBT are superior to STT for H. pylori eradication when adjusted for country-specific antibiotic resistance and CYP2C19 polymorphism in a sample of individuals residing in five countries within two continents.

Behind the Headset: Predictive Accuracy of Patient-Reported Outcome Measures for Voice Symptoms in Call Centers

Objective: This study examines factors predicting self-reported voice symptoms in call center workers. Methods: Multivariate analysis and predictive modeling assess personal, work-related, acoustic, and behavioral factors. Generalized Linear Models (GLMs) and Receiver Operating Characteristic (ROC) curves are employed. Results: Age and sleep patterns impacted voice quality and effort, while workplace factors influenced symptom perception. Unhealthy vocal behaviors related to tense voice and increased effort, while hydration was protective. Voice acoustics showed diagnostic potential, supported by ROC data. These findings emphasize voice symptom complexity in call center professionals, necessitating comprehensive assessment. Limitations: This study recognizes its limitations, including a moderate-sized convenience sample and reliance on PROM metrics. Future research should incorporate more objective measures in addition to self-reports and acoustic analysis. Value: This research provides novel insights into the interplay of personal, occupational, and voice-related factors in developing voice symptoms among call center workers. Predictive modeling enhances risk assessment and understanding of individual susceptibility to voice disorders. Conclusion: Results show associations between various factors and self-reported voice symptoms. Protective factors include sleeping more than six hours and consistent hydration, whereas risk factors include working conditions, such as location and behaviors like smoking. Diagnostic models indicate good accuracy for some voice symptom PROMs, emphasizing the need for comprehensive models considering work factors, vocal behaviors, and acoustic parameters to understand voice issues complexity.

Objetivo: Este estudio examina los factores que predicen los síntomas de voz en los trabajadores de call centers. Métodos: Se utilizan análisis multivariados y modelos predictivos para evaluar factores personales, laborales, acústicos y de comportamiento. Se emplean Modelos Lineales Generalizados (GLM) y curvas ROC. Resultados: La edad y los patrones de sueño afectaron la calidad vocal y el esfuerzo, mientras que los factores laborales influyeron en la percepción de síntomas. Los comportamientos vocales no saludables se relacionaron con voz tensa y mayor esfuerzo, mientras que la hidratación fue protectora. Los parámetros acústicos de voz mostraron potencial diagnóstico respaldado por datos de ROC. Los hallazgos subrayan complejidad de síntomas vocales en profesionales de centros de llamadas, requiriendo una evaluación integral. Limitaciones: Este estudio reconoce sus limitaciones, que incluyen una muestra de conveniencia de tamaño moderado y la dependencia de medidas PROMs. Futuras investigaciones deberían incorporar medidas objetivas, además de los autorreportes y análisis acústico. Importancia: Esta investigación aporta nuevos conocimientos sobre factores personales, laborales y síntomas de voz en trabajadores de call centers. El modelado predictivo mejora la evaluación de riesgos y la comprensión de la susceptibilidad individual a trastornos de la voz. Conclusión: Los resultados muestran asociaciones entre diversos factores y los síntomas vocales reportados. Los factores de protección incluyen dormir más de seis horas y una hidratación constante; los factores de riesgo incluyen las condiciones de trabajo, como la ubicación y comportamientos como fumar. Los modelos de diagnóstico indican una buena precisión para algunas PROMs de síntomas de la voz, lo que subraya la necesidad de modelos integrales que tengan en cuenta los factores laborales, los comportamientos vocales y los parámetros acústicos para comprender la complejidad de los problemas de la voz.

[Reduction in Helicobacter pylori infection among patients referred for upper gastrointestinal endoscopy in Santiago, Chile, between 2010-2020]. / Reducción de la infección por Helicobacter pylori en pacientes derivados a endoscopia digestiva alta en Santiago de Chile entre 2010-2020.

Latin America presents a high prevalence of Helicobacter pylori(Hp) infection. Between1996-2003, the prevalence in Santiago, Chile, was 70%; recent studies indicate a decreasein this infection. Updating the frequency of Hp is crucial due to its associated health impact. OBJECTIVE: Our objective was to describe the trend in Hp infection in patients undergoingambulatory esophagogastroduodenoscopy (EGD) in a Chilean population. MATERIALS AND METHODS: A retrospective observational study was conducted on patients over 18 years old who attended a first EGD with a rapid urease test between 2010-2020. Time trendswere described through time series analysis. A Poisson model was constructed to estimatethe risk of infection, adjusted for age and gender. RESULTS: 11,355 patients were included[66.9% females; mean age 52 years; Hp 41.6%]. Male gender presented a higher frequencyof Hp infection [RR 1.13; (95% CI: 1.08-1.18)].Hp frequency infection decreased significantlyfrom 45.1% in 2010 to 29% in 2020, with a 36% lower probability of Hp infection in 2020 compared to 2010 [RR 0.64;(95% CI: 0.55-0.74)]. A progressive decline in Hp infectiontrend was projected, reaching values close to 25% by year 2025. CONCLUSION: A significantreduction in Hpinfection was observed between 2010-2020. This decrease could be explained by the implementation of public health policies in the last decade associated with socio-sanitary changes.

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.

Reducción de la infección por Helicobacter pylori en pacientes derivados a endoscopia digestiva alta en Santiago de Chile entre 2010-2020 / Reduction in Helicobacter pylori infection among patients referred for upper gastrointestinal endoscopy in Santiago, Chile, between 2010-2020

RESUMEN Latinoamérica presenta una alta prevalencia de infección por Helicobacter pylori (Hp). Entre 1996-2003 la prevalencia en Santiago de Chile fue del 70%; estudios recientes presentan una disminución en esta infección. Actualizar la frecuencia de Hp es fundamental debido a su impacto en la salud asociado. Objetivo: Nuestro objetivo fue describir la tendencia de la infección por Hp en pacientes que asisten a endoscopía digestiva alta (EDA) ambulatoria en una población chilena. Materiales y métodos: Se realizó un estudio observacional retrospectivo de pacientes mayores de 18 años que asistieron a una primera EDA con test rápido de ureasa entre 2010-2020. La tendencia en el tiempo fue descrita mediante análisis de series de tiempo. Se construyó un modelo Poisson para estimar el riesgo de infección, ajustado por edad y sexo. Resultados: Se incluyeron 11 355 pacientes [66,9% mujeres; edad media 52 años; Hp 41,6%]. El sexo masculino presentó una mayor frecuencia de infección por Hp [RR 1,13; (IC95%:1,08-1,18)]. La frecuencia de Hp disminuyó significativamente desde 45,1% en 2010 hasta 29% en 2020, con 36% menor probabilidad de presentar infección por Hp en 2020 con respecto al 2010 [RR 0,64; (IC95%:0,55-0,74)]. Se proyectó un descenso progresivo en la tendencia de infección por Hp hasta valores cercanos al 25% para el año 2025. Conclusión: Se observó una reducción significativa en la infección por Hp entre los años 2010-2020. Esta disminución pudiese ser explicada mediante la incorporación de políticas públicas de salud en la última década asociadas a cambios sociosanitarios.

Association between public health policies on alcohol and worldwide cancer, liver disease and cardiovascular disease outcomes.

BACKGROUND & AIMS: The long-term impact of alcohol-related public health policies (PHPs) on disease burden is unclear. We aimed to assess the association between alcohol-related PHPs and alcohol-related health consequences. METHODS: We conducted an ecological multi-national study including 169 countries. We collected data on alcohol-related PHPs from the WHO Global Information System of Alcohol and Health 2010. Data on alcohol-related health consequences between 2010-2019 were obtained from the Global Burden of Disease database. We classified PHPs into five items, including criteria for low, moderate, and strong PHP establishment. We estimated an alcohol preparedness index (API) using multiple correspondence analysis (0 lowest and 100 highest establishment). We estimated an incidence rate ratio (IRR) for outcomes according to API using adjusted multilevel generalized linear models with a Poisson family distribution. RESULTS: The median API in the 169 countries was 54 [IQR 34.9-76.8]. The API was inversely associated with alcohol use disorder (AUD) prevalence (IRR 0.13; 95% CI 0.03-0.60; p = 0.010), alcohol-associated liver disease (ALD) mortality (IRR 0.14; 95% CI 0.03-0.79; p = 0.025), mortality due to neoplasms (IRR 0.09; 95% CI 0.02-0.40; p = 0.002), alcohol-attributable hepatocellular carcinoma (HCC) (IRR 0.13; 95% CI 0.02-0.65; p = 0.014), and cardiovascular diseases (IRR 0.09; 95% CI 0.02-0.41; p = 0.002). The highest associations were observed in the Americas, Africa, and Europe. These associations became stronger over time, and AUD prevalence was significantly lower after 2 years, while ALD mortality and alcohol-attributable HCC incidence decreased after 4 and 8 years from baseline API assessment, respectively (p <0.05). CONCLUSIONS: The API is a valuable instrument to quantify the robustness of alcohol-related PHP establishment. Lower AUD prevalence and lower mortality related to ALD, neoplasms, alcohol-attributable HCC, and cardiovascular diseases were observed in countries with a higher API. Our results encourage the development and strengthening of alcohol-related policies worldwide. IMPACT AND IMPLICATIONS: We first developed an alcohol preparedness index, an instrument to assess the existence of alcohol-related public policies for each country. We then evaluated the long-term association of the country's alcohol preparedness index in 2010 with the burden of chronic liver disease, hepatocellular carcinoma, other neoplasms, and cardiovascular disease. The strengthening of alcohol-related public health policies could impact long-term mortality rates from cardiovascular disease, neoplasms, and liver disease. These conditions are the main contributors to the global burden of disease related to alcohol use. Over time, this association has not only persisted but also grown stronger. Our results expand the preliminary evidence regarding the importance of public health policies in controlling alcohol-related health consequences.

Impacto de la pandemia por COVID-19 en la conducta alimentaria de niñas, niños y adolescentes con trastorno del espectro autista / Impact of the COVID-19 pandemic on the eating behaviors of children and adolescents with autism spectrum disorder

Introducción. Los niños con trastorno del espectro autista (TEA) presentan dificultades de adaptación a situaciones estresantes, como la pandemia por COVID-19. Objetivo. Evaluar el impacto del primer año de pandemia en las dificultades alimentarias de niños con TEA. Población y métodos. Se invitó a participar a cuidadores de niños con TEA no sindromático (edad: 2-18 años) de una unidad de neurodesarrollo. Los participantes respondieron en línea un cuestionario y la escala de evaluación de problemas de conducta alimentaria (BPFAS por su sigla en inglés) antes y durante el primer año de pandemia. Se calculó un puntaje de prioridad (producto entre promedio de frecuencia y problema) para cada ítem del BPFAS. Resultados. El 56,6 % (86/152) de los cuidadores contestó la encuesta (madre 74,4 %), mediana de edad 6,3 años (p25-p75: 4,7-8,2); el 80,2 % de los niños eran de sexo masculino; el 58,1 % mantuvo terapia durante la pandemia y el 61,6 % presentaba problemas de comportamiento previo a esta. Durante el primer año de pandemia, los niños presentaron mayor intensidad en dificultades conductuales (34,9 %) y de alimentación (61,6 %); sin embargo, el 31,4 % refirió mejoría en la alimentación. No existieron diferencias significativas entre puntajes BPFAS antes y durante la pandemia. Los ítems con mayor puntaje de prioridad fueron "se levanta de la mesa durante la hora de comer", "no probar alimentos nuevos", "no come verduras", "no come frutas". Conclusiones. Hubo alta frecuencia de dificultades en las conductas alimentarias durante el primer año de pandemia. No se presentaron diferencias en las características de estas conductas antes y durante la pandemia.

Introduction. Children with autism spectrum disorder (ASD) have difficulties adapting to stressful situations, such as the COVID-19 pandemic. Objective. To assess the impact of the first year of the pandemic on feeding difficulties in children with ASD. Population and methods. The caregivers of children and adolescents with non-syndromic ASD (age: 2­18 years) from a neurodevelopment unit were invited to participate. Participants completed a questionnaire and the Behavioral Pediatrics Feeding Assessment Scale (BPFAS) online before and during the first year of the pandemic. A priority score (product between the average frequency and the problem) for each BPFAS item was estimated. Results. Among the caregivers, 56.6% (86/152) completed the survey (mother: 74.4%); children's median age was 6.3 years (p25­p75: 4.7­8.2); 80.2% of children were males; 58.1% continued with their therapy during the pandemic; and 61.6% had behavioral problems before the pandemic. During the first year of the pandemic, children had greater behavioral problems (34.9%) and feeding difficulties (61.6%); however, 31.4% of caregivers referred improvements in feeding. There were no significant differences in the BPFAS scores before and during the pandemic. The following items obtained the highest priority scores: gets up from table during meal, does not try new food, does not eat vegetables, does not eat fruits. Conclusions. A high frequency of feeding difficulties was noted during the first year of the pandemic. No differences were observed in feeding characteristics before and during the pandemic.

Barreras para las actividades de investigación en los programas de residencia: estudio de métodos mixtos / Barriers for research activities in residency programs: A mix-methods study

Introducción Las actividades de investigación tienen un impacto positivo en el rendimiento de los médicos residentes. Falta información sobre investigaciones desarrolladas por residentes de países en vías de desarrollo. Nuestro objetivo fue evaluar las barreras y facilitadores para la investigación en programas de residencia en una Facultad de Medicina de América Latina. Métodos Se llevó a cabo un diseño de estudio de metodología mixta. Utilizamos un enfoque de teoría fundamentada para la fase cualitativa, recopilando los datos a través de entrevistas semiestructuradas y grupos focales con profesores y residentes. Para la fase cuantitativa, se administraron encuestas a residentes y profesores. Para evaluar las propiedades psicométricas de las encuestas utilizamos análisis factorial y scree plot (validez); alfa de Cronbach y coeficiente de Correlación Intraclase (confiabilidad). Resultados Se realizaron grupos focales que incluyeron diez profesores y quince residentes, y se identificaron los siguientes dominios: a) facilitadores para la participación de los residentes, b) barreras, c) estrategias para introducir la investigación en el currículo, d) argumentos que respaldan las actividades de investigación durante la residencia, y e) perfil de los residentes motivados en la investigación. Tanto los residentes como el profesorado identificaron la falta de tiempo protegido y la ausencia de tutoría adecuada como las principales barreras. Se encontró una brecha de género relacionada con las publicaciones internacionales (34% vs 66% mujeres/hombres), las mujeres percibieron que las actividades de investigación 'compiten con otras actividades' (OR: 2.04, IC 95% 1.03 a 4.07). Conclusiones Los residentes y profesores de una universidad latinoamericana de alta productividad valoran mucho la investigación. La presencia de brecha de género, la falta de tiempo protegido y de tutorías destacan como las principales barreras. Las estrategias propuestas para mejorar la investigación dentro de los programas de residencia son: establecer un programa de tutoría interdisciplinario entre residentes e investigadores; promover las rotaciones electivas; y premiar propuestas que consideren la equidad de género.

Introduction Research activities have a positive impact on the performance of residents. However, information on research conducted by residents from developing countries is scarce. Our study sought to identify the barriers and facilitators for developing research in medical residency programs in a Latin-American faculty of medicine. Methods A mixed methodology study design was carried out. We used a grounded theory approach for the qualitative phase, collecting data through semi-structured interviews and focus groups with faculty and residents. For the quantitative phase, surveys were administered to residents and teachers. We used factor analysis and scree plot (validity), Cronbach's alpha, and Intraclass correlation coefficient (reliability) to evaluate the surveys' psychometric properties. Results Focus groups involving ten faculty members and 15 residents were conducted, and the following domains were identified: a) facilitators for resident participation, b) barriers, c) strategies for introducing research into the curriculum, d) arguments supporting research activities throughout medical residency, and e) profile of research-motivated residents. Both residents and faculty members identified a lack of protected time and adequate mentoring as the major barriers. A gender gap was found related to international publications (34% vs. 66% women/men); women perceived that research activities 'compete with other activities' (OR: 2.04, 95% CI 1.03 to 4.07). Conclusions Research is highly valued by both residents and faculty members at a Latin-American university with a strong academic output. Major barriers to promoting research in this context include lack of protected time and effective mentoring, and gender gaps. Strategies proposed to improve research within medical residency programs include: establishing an interdisciplinary mentoring program between residents and researchers, promoting elective rotations, and rewarding proposals that consider gender equity.

Evaluation of trefoil factor 3 as a non-invasive biomarker of gastric intestinal metaplasia and gastric cancer in a high-risk population.

BACKGROUND: Adenocarcinoma is preceded by chronic atrophic gastritis, gastric intestinal metaplasia and dysplasia. Trefoil factor 3 (TFF3) is a peptide secreted by goblet cells, which is abundantly present in intestinal metaplasia. AIM: To evaluate the utility of serum TFF3 as a non-invasive biomarker for the diagnosis of intestinal metaplasia and gastric cancer. METHODS: Single-center, cross-sectional study of 274 patients who consecutively underwent upper gastrointestinal endoscopy with gastric biopsies (updated Sydney system). TFF3 levels were measured in serum by a commercial ELISA kit. Patients with normal histology or chronic atrophic gastritis without intestinal metaplasia comprised the control group. In addition, 14 patients with invasive gastric cancer were included as a reference group. The association between TFF3 levels and intestinal metaplasia was assessed by logistic regression. RESULTS: Patients with intestinal metaplasia (n=110) had a higher median TFF3 level as compared to controls (n=164), 13.1 vs. 11.9ng/mL, respectively (p=0.024). Multivariable logistic regression showed a no significant association between TFF3 levels and intestinal metaplasia (OR=1.20; 95%CI: 0.87-1.65; p-trend=0.273). The gastric cancer group had a median TFF3 level of 20.5ng/mL, and a significant association was found (OR=3.26; 95%CI: 1.29-8.27; p-trend=0.013). CONCLUSION: Serum levels of TFF3 do not discriminate intestinal metaplasia in this high-risk Latin American population. Nevertheless, we confirmed an association between TFF3 levels and invasive gastric cancer.

Public Health Measures and Prevention of Alcohol-Associated Liver Disease.

Hazardous alcohol consumption causes approximately 4% of deaths globally, constituting one of the leading risk factors for the burden of the disease worldwide. Alcohol has several health consequences, such as alcohol-associated liver disease, hepatocellular carcinoma, nonliver neoplasms, physical injury, cardiac disease, and psychiatric disorders. Alcohol misuse significantly affects workforce productivity, with elevated direct and indirect economic costs. Due to the high impact of alcohol consumption on the population, public health has led to the development of a range of strategies to reduce its harmful effects. Regulatory public health policies (PHP) for alcohol can exist at the global, regional, international, national, or subnational levels. Effective strategies incorporate a multilevel, multicomponent approach, targeting multiple determinants of drinking and alcohol-related harms. The World Health Organization categorizes the PHP into eight categories: national plan to fight the harmful consequences of alcohol, national license and production and selling control, taxes control and pricing policies, limiting drinking age, restrictions on alcohol access, driving-related alcohol policies, control over advertising and promotion, and government monitoring systems. These policies are supported by evidence from different populations, demonstrating that determinants of alcohol use depend on several factors such as socioeconomic level, age, sex, ethnicity, production, availability, marketing, and others. Although most policies have a significant individual effect, a higher number of PHP are associated with a lower burden of disease due to alcohol. The excessive consequences of alcohol constitute a call for action, and clinicians should advocate for developing and implementing a new PHP on alcohol consumption.

Effect of an intervention on teachers' and teaching assistants' attitudes and academic expectations concerning the educational inclusion of students with Down's Syndrome / Efecto de una intervención en actitudes y expectativas de aprendizaje de profesores y asistentes de la educación hacia la inclusión escolar de estudiantes con síndrome de Down

ABSTRACT Purpose: to assess the effect of an intervention on educational teams' attitudes and academic expectations concerning the inclusion of students with Down's Syndrome (DS), in Chile. Methods: a quasi-experimental single-group study was carried out, with an interdisciplinary pilot intervention held comprising three workshops on inclusive education for teachers and teaching assistants. The Attitudes Towards and Academic Expectations For Down's Syndrome Students questionnaire (CAEASD in Spanish) was used to assess these variables pre- and post-intervention. Results: 48 subjects participated in this study, with 37 in the experimental group and 11 in the control group. No significant differences were observed in the overall CAEASD score, neither before nor after the intervention (p=0.388). However, in the actions part of the attitude component, there was a significant difference in the experimental group (p<0.05), in which, the proportion of positive changes in the overall CAEASD score was also greater than that in the control group. Conclusion: mentoring had a positive impact on educational teams' attitudes towards students with DS, helping to develop an inclusive educational community.

RESUMEN Objetivo: evaluar el efecto de una intervención en las actitudes y expectativas de aprendizaje que presentan profesores y asistentes de la educación hacia la inclusión escolar de estudiantes con síndrome de Down (SD) en Chile. Métodos: se realizó un estudio cuasi-experimental de grupo único donde se implementó una intervención interdisciplinaria piloto de tres talleres sobre orientaciones inclusivas a profesores y asistentes de la educación. Se aplicó el cuestionario de Actitudes y Expectativas de Aprendizajes respecto a los estudiantes con SD (CAEASD) para medir estas variables pre y post intervención. Resultados: 48 sujetos participaron de la intervención, 37 conformaron el grupo experimental y 11 el grupo control. No existieron diferencias significativas en el puntaje global del CAEASD, previo y posterior a la intervención (p=0,388), sin embargo, se observó una diferencia significativa en la medición pre y post en el componente Acción de las actitudes en el grupo experimental (p<0,05). Además, el grupo experimental presentó una mayor proporción de puntuaciones con cambios positivos que el grupo control en el puntaje global del cuestionario CAEASD. Conclusión: la intervención generó cambios positivos en las actitudes del equipo escolar hacia los estudiantes con SD, lo que contribuye en el desarrollo de una comunidad educativa inclusiva.

Auditory effects of recreational and occupational noise exposure among dental students: a cross-sectional study / Efectos auditivos producto de la exposición a ruido recreacional y dental en estudiantes de odontología: un estudio transversal

ABSTRACT Purpose: to determine the auditory effects of noise exposure from recreational and occupational sources among dentistry students. Methods: forty-two dentistry students, routinely exposed to occupational noise, and 72 students from other health science schools were recruited (control group). Audiometric testing, otoacoustic emissions and questionnaires to assess recreational and occupational noise were applied to the sample. The presence of a notch was determined for each participant audiometry´s test based on the criteria proposed by Coles et al. Differences in notch prevalence were analyzed by applying univariate regression models as well as a multivariate model adjusted by covariates. Results: non-significant differences in auditory thresholds between groups were found. The controls exhibited a significantly higher prevalence of a notch at 4 kHz than the group exposed to noise. However, the differences were not statistically significant in the multivariate model adjusted by recreational noise exposure. Conclusions: the occupational noise exposure was not significantly associated to auditory system dysfunction. In addition, the differences in notch prevalence could be related to recreational noise exposure.

RESUMEN Objetivo: determinar los efectos auditivos producto de la exposición a ruido recreacional y ocupacional en estudiantes de Odontología. Métodos: se reclutó a 42 estudiantes de odontología expuestos rutinariamente a ruido ocupacional, y a 72 estudiantes de otras carreras del área de la salud (grupo control). Se evaluó mediante audiometría, emisiones otoacústicas, junto con aplicar cuestionarios para determinar la exposición a ruido ocupacional y recreacional. A partir de los umbrales audiométricos e determinó la presencia de escotoma usando el criterio de Coles et al. Se analizaron las diferencias en prevalencia de escotomas entre los grupos mediante regresiones logísticas, ajustando por otras variables. Resultados: no existieron diferencias significativas en los umbrales audiométricos entre los grupos estudiados. El grupo control mostró mayor prevalencia de escotoma en 4 kHz al ajustar por sexo y edad, sin embargo, dejó de ser significativa al ajustar adicionalmente por exposición a ruido recreacional. Conclusiones: la exposición a ruido ocupacional no se asoció a alteraciones auditivas. Además, las diferencias en prevalencia de escotomas estarían relacionadas a exposición a ruido recreacional.

Abstract Introduction: It is estimated that up to 30% of the population over 65 years of age present hearing loss. A validated intervention for hearing loss in older adults is the use of hearing aids, but the problem is that up to 50% of older adults do not use them. Aim: To estimate the hearing aid adherence in elderly population with hearing loss who are beneficiaries of the GES program "Bilateral hearing loss in people over 65 who require hearing aids" in a hospital in Santiago, Chile. Material and Method: The control arm of a randomized clinical trial was used to estimate adherence to hearing aid with validated and structured questionnaires, by trained interviewers who visited the beneficiaries of the program at three, six, nine and twelve months posterior to the intervention. Results: 101 older adults were included. The average age was 76.3 years. When analyzing adherence as "use for more than 8 hours a day during the last two weeks", adherence at 3 months was 56.8%, at 6 months 62.6%, at 9 months 63.2%, and at 12 months 54.5%. When analyzing considering use between 4-8 h/day, the adherence during the follow-up was between 73.8% and 87.3%. According to Dr. Yueh's questionnaire, adherence at 3 months was 64.7%, at 6 months 63.9%, at 9 months 73.7%, and at 12 months 67.8%. Conclusion: The results of the present analysis show an excellent adherence to hearing aids in a group of Chilean population, which represents a positive outcome regarding the effectiveness of this particular public policy.

Sensibilidad y especificidad del Test ScreeLing en usuarios afásicos en etapa aguda: un análisis preliminar / Sensitivity and Specificity of the Spanish version of the ScreeLing Test in aphasic patients at the acute phase: a pilot study

En Chile, entre un 20% y un 38% de los usuarios que sufren un ataque cerebro-vascular (ACV) presentan afasia. Pese a su alta prevalencia no existen herramientas validadas que permitan realizar una caracterización lingüística temprana de la afasia. Por lo anterior, el objetivo del presente trabajo es analizar la sensibilidad y especificidad de la versión en español del ScreeLing en una muestra de usuarios afásicos después de producido un ACV. Se trata de un estudio transversal analítico en el cual se aplicó el test ScreeLing a 13 usuarios afásicos tras primer evento de ACV en etapa aguda (< 6 semanas tras ACV) y a 56 adultos neurológicamente sanos. Adicionalmente, se evaluó el nivel comprensivo y el lenguaje espontáneo de usuarios con afasia, con la versión abreviada del Token Test y Escala de Severidad de la Afasia (ASRS). Se construyeron modelos mediante regresiones logísticas, obteniendo sus respectivas áreas bajo la curva ROC. Los resultados muestran que el equilibrio entre sensibilidad y especificidad para el puntaje global del test ScreeLing se estableció en 67 puntos, obteniendo una sensibilidad del 94,6% y especificidad del 100%. El área bajo la curva ROC alcanzó 0,99 (IC 95%: 0,97-1,00). En las subpruebas sintáctica y fonológica se alcanzó un puntaje de corte de 21 puntos, mientras que en la subprueba semántica se lograron 22 puntos. Se concluye que el ScreeLing en español posee una alta sensibilidad y especificidad para la detección de déficits lingüísticos post ACV similar a los resultados encontrados en la versión original del test en holandés. Esfuerzos futuros deben concentrarse en ampliar la muestra de usuarios afásicos con distintos perfiles de severidad.

In Chile, aphasia is present in 20% to 30% of stroke patients. Currently, speech and language therapists do not have a standardized test to characterize aphasic patients' linguistics disorders at the acute phase. The aim of this study iso analyze the sensibility and specificity of the Spanish version of the ScreeLing test in aphasic patient post-stroke at the acute stage. To do so, in a transversal study design, acute aphasic patients (< 6 weeks post-stroke) and healthy adults were evaluated with the Spanish version of the ScreeLing test. Additionally, language comprehension and spontaneous speech were assessed with the shortened version of the Token Test and the Aphasia Severity Rating Scale, respectively. We calculated the Area Under ROC Curve (AUC) to choose the cut-off that provided the best balance between sensibility and specificity. We included 13 aphasic patients and 56 healthy adults. The best balance between sensibility and specificity was found to be with 67 points, with a sensibility of 94,6% andspecificity of 100%. The AUC ROC was 0,99 (IC 95%: 0,97-1,00). For the subtest measuring syntax and phonology, the cut-off score was 21 points, and for the semantic subtest, 22 points. In conclusion, the Spanish version of the ScreeLing test, similar to its original Dutch version, demonstrated high specificity and sensibility to detect linguistic deficits in acute aphasic patients post-stroke. Future efforts aim to increase the sample size of patients considering differentlanguage severity profiles.

Aprendizaje interprofesional en los internados de las carreras de la salud del Hospital Josefina Martínez / Interprofessional learning of interns at Josefina Martínez Hospital

Introducción: las dinámicas de atención en salud requieren que los profesionales que componen el equipo de salud trabajen en for-ma colaborativa. Sin embargo, durante su formación, las oportunidades de aprendizaje con otras disciplinas son escasas. Se reportan los resultados del primer proyecto para promover el aprendizaje interprofesional en los internos que rotan por el Hospital Josefina Martínez. Método: de marzo a julio 2018, se realizó un taller constituido por dos sesiones, en cada rotación de internado. Participaron internos de cinco carreras en forma conjunta (kinesiología, odontología, nutrición, fonoaudiología y terapia ocupacional). Se adaptó la encuesta de disposición al aprendizaje interprofesional, para ser aplicada antes y después de cada taller. Se calcularon las medianas, rangos intercuartílicos (Q1; Q3y se compararon los puntajes mediante test de Wilcoxon. Resultados: hubo una disposición positiva inicial al aprendizaje interprofesional, con mejoría significativa después de los talleres en todas las dimensiones de la encuesta: Trabajo en equipo y colaboración (<0,001), trabajo centrado en el paciente (<0,001), y sentido de identidad profesional (<0,05). La diferencia del puntaje global de la encuesta también fue significativa (<0,001). Conclusiones: se demostró un cambio favorable y significativo en las respuestas de los internos después de los talleres, en todas las dimensiones de la encuesta. En los comentarios, destacaron la relevancia de aprender con estudiantes de otras carreras, describiendo que aumentó su conocimiento sobre éstas y reforzando el impacto que dicha integración tiene en mejorar la atención y resolución de problemas en salud.

Background: The dynamics of health care require that the health professionals work collaboratively; however, during their training, learning opportunities with other disciplines are infrequent. The results of the first project to promote interprofessional learning in the clinical internship at Hospital Josefina Martínez are reported. Methods: From March to July 2018, two workshops for each internship rotation were carried. Students from fivecareers participated together (Kinesiology, Dentistry, Nutrition, Speech Therapy, and Occupa-tional Therapy). The readiness to interprofessional scale survey was adapted, to be applied before and after each workshop. Medians, interquartile range (Q1; Q3) were calculated, and the Wilcoxon test was used to compare the results. Results: There was an initial po-sitive readiness for interprofessional learning, with a significant improvement in all the dimensions of the survey, after the workshops: Teamwork and collaboration (<.001), patient-centered care (<.001), and sense of professional identity (<.05). The differences from the overall survey were also significant (<0.001). Conclusions: A favorable change was demonstrated in the responses of the students after the workshops, overalland in all the dimensions of the survey. In the comments, the students highlighted the relevance of learning with students from other careers, describing that it increased their knowledge about different professions and strengthening the impact that this integration has in improving attention and resolving health problems.

Resultados del programa nacional de implantes cocleares y garantías explícitas en salud en beneficiarios pertenecientes al servicio de salud Aconcagua / Results of the national program of cochlear implants and explicit health guarantees in beneficiaries belonging to the Aconcagua health service

Resumen Introducción: En Chile, desde la ejecución de políticas públicas vinculadas a la implementación de implantes cocleares, sólo existen estudios elaborados y publicados en la Región Metropolitana que han buscado describir los resultados que estas han alcanzado en la población. Objetivo: Describir los resultados del Programa Nacional de Implantes Cocleares y Garantías Explícitas en Salud en pacientes beneficiados pertenecientes al Servicio de Salud Aconcagua. Material y Método: Estudio de corte transversal. Se reportan los resultados de la totalidad de pacientes beneficiados implantados en el período 2003-2016 del Servicio de Salud Aconcagua. Resultados: Del total de personas postuladas a nivel nacional, el 3% (n = 17) fueron postuladas desde el Servicio de Salud Aconcagua, de las cuales, el 58,8% (n = 10), fueron beneficiadas con implante coclear. La totalidad de los beneficiados fueron pesquisados a través de consulta en policlínico de Otorrinolaringología. La mediana de diagnóstico auditivo fue 22 meses (Q1-Q3:16-24), implementación de audífonos 24 meses (Q1-Q3:17-25), implementación de implante coclear 50 meses (Q1-Q3:29-56) y encendido de 52 (Q1-Q3:33-57). La mediana de ganancia funcional con implante fue 58,4 dB (Q1-Q3:46-65); estadísticamente significativa (p < 0,05). Conclusión: Los resultados en pacientes usuarios de implante coclear son satisfactorios. Es necesario ampliar la cobertura de estas políticas en el valle del Aconcagua, en coherencia con la mejora de procesos vinculados al diagnóstico oportuno de hipoacusia y posterior implementación de ayudas auditivas en tiempos que la evidencia sugiere pertinentes.

Abstract Introduction: In Chile, since the implementation of public policies linked to the program of cochlear implants, the only published studies were prepared in the Metropolitan Region, that have sought to describe the results that these responses have obtained in the population. Aim: Describe the results of the National Cochlear Implants Program and explicit health guarantees in beneficiary patients belonging to Aconcagua health service. Material and Method: Cross-sectional study. The results of all the patients benefited implanted in the period 2003-2016 are reported. Results: Of the total number of people nominated nationwide, 3% (n = 17) were chosen from the Aconcagua health service, of which 58.8% (n = 10) were benefited with cochlear implants. All the benefited patients were investigated through consultation in the Otolaryngology polyclinic. The median auditory diagnosis was 22 months (Q1-Q3: 16-24), hearing aid implementation 24 months (Q1-Q3: 17-25), cochlear implant implementation 50-month (Q1-Q3: 29-56) and on of cochlear implant 52 months (Q1-Q3: 33-57). The median functional gain with implant was 58.4 dB (Q1-Q3: 46-65); statistically significant (p < 0.05). Conclusion: The results in patients using cochlear implants are satisfactory. It is necessary to expand the coverage of these public policies in the Aconcagua valley, consistent with the improvement of the processes related to the timely diagnosis of hearing loss and subsequent implementation of hearing aids in the times that the relevant evidence.

Metabolic health and its association with lifestyle habits according to nutritional status in Chile: A cross-sectional study from the National Health Survey 2016-2017.

BACKGROUND: Lifestyle habits associate with metabolic health in overall populations. Whether such association is similar among subjects with a different nutritional status has been less studied. We aimed to (i) determine the prevalence of metabolic phenotypes in Chile, and (ii) determine the association between lifestyle habits and metabolic health according to the nutritional status. METHODS: The National Health Survey of Chile 2016-2017 was analyzed. A metabolically unhealthy phenotype was defined as manifesting ≥3 of the following risk factors: elevated blood pressure, elevated triglycerides, elevated glucose, elevated waist circumference, or reduced high-density lipoprotein cholesterol. Individuals manifesting <2 risk factors were considered as healthy. The nutritional status was defined as normal weight (18.5 to <25 kg/m2), overweight (25 to <30 kg/m2) or obesity (≥30 kg/m2). Questionnaires were used to estimate smoking habits, alcohol intake, sedentary behavior, moderate-vigorous physical activity, fruits/vegetables consumption, and fish/seafood consumption. The association (odds ratio [95%CI]) between lifestyle habits and metabolic health was determined within each nutritional status, adjusting for age, sex, BMI (in kg/m2), and education. RESULTS: The prevalence of a metabolically unhealthy phenotype was 36% in the overall sample. Such a prevalence was 7%, 33% and 58% among subjects with normal weight, overweight and obesity, respectively. In subjects with normal weight, the highest quartile of fruits/vegetables consumption was associated with reduced odds of having a metabolically unhealthy phenotype (0.09 [0.01-0.48]). In subjects with obesity, the highest quartile of moderate-vigorous physical activity was associated with reduced odds of having a metabolically unhealthy phenotype (0.29 [0.09-0.91]). CONCLUSION: One third of the Chilean population manifests an unhealthy phenotype. We identified associations between lifestyle habits and metabolic health that are specific to the nutritional status. Thus, emphasizing fruits/vegetables consumption in subjects with normal weight, and physical activity in subjects with obesity, may maximize the benefits of public health interventions.
