Abstract Background Brazil faces notable Breast Cancer (BC) mortality despite lower incidence rates versus developed countries. Despite guidelines from medical societies, Brazilian public policy recommends biennial mammographic screening for women aged 50 to 69. This study investigates sociodemographic and clinical factors related to BC detection methods and clinical stage at diagnosis. Methods The authors conducted a cross-sectional study at a São Paulo tertiary hospital. Patients were divided into ‘symptomatic’ and ‘mammographic’ detection groups. Bivariate analyses by detection method and clinical stage compared groups' profiles in terms of sociodemographic and clinical characteristics. Poisson regression analyses assessed sociodemographic and molecular subtypes´ influence on “mammographic detection” prevalence and “advanced-stage BC”, reporting prevalence ratios and 95 % Confidence Intervals. Results The authors studied 1,536 BC patients admitted from January 2016 to December 2017. The “mammographic detection” group had a higher proportion of patients aged 50‒69 years (62.9 % vs. 44.1 %), white race (63.3 % vs. 51.6 %), Catholic religion (58.2 % vs. 51.1 %), and Luminal A subtype (25.2 % vs. 13.2 %) compared to the “symptomatic detection” group. Patients with early-stage disease were more likely to have higher education levels (8.1 % vs. 5.5 %) and be married (39.8 % vs. 46.6 %) compared to those with advanced-stage. Molecular subtypes were significantly associated with the detection method and stage. The prevalence of advanced-stage disease in "mammographic" (n=313) and "symptomatic" (n=1191) groups was 18.5 % and 55 %, respectively . Mammographic detection significantly reduced advanced-stage BC prevalence (PR = 0.40, 95 % CI 0.31‒0.51). Conclusion Mammographic detection reduces advanced-stage breast cancer prevalence in Brazil, emphasizing the importance of regular screenings, especially among at-risk sociodemographic groups. Enhancing mammographic screening accessibility, lowering the starting age to 40, and extending coverage to include annual mammograms can significantly lower breast cancer mortality in Brazil, benefiting public health and patient outcomes.

ABSTRACT Introduction: With the introduction of minimally invasive cardiac surgery, more commonly cases of lung herniation are starting to appear. Acquired lung hernias are classified as postoperative, traumatic, pathologic, and spontaneous. Up to 83% of lung hernias are intercostal. Herein, we describe patients presenting with intercostal lung hernias following minimally invasive cardiac surgery at a single center in Medellín, Colombia. Methods: We conducted a retrospective search of all patients presenting with intercostal lung hernias secondary to minimally invasive cardiac surgery at our clinic in Medellín since the beginning of our program, from 2010 to 2022. Mini-sternotomies were excluded from our study. We reviewed the incision type and other possible factors leading to intercostal lung hernia development. We also describe the approach taken for these patients. Results: From 2010 up until 2022, 803 adult patients underwent minimally invasive cardiac surgeries through a mini-thoracotomy. At the time of data retrieval, nine patients presented with intercostal lung hernias at the previous incision site. Five hernias (55%) were from right 2nd intercostal parasternal mini-thoracotomies for aortic valve surgeries. Four hernias (45%) were from right 4th intercostal lateral mini-thoracotomies for mitral valve surgeries. Our preferred repair technique is a video-assisted thoracoscopic mesh approach. Conclusion: Minimally invasive cardiac surgical approaches are becoming more routine. Proper wound closure is critical in preventing lung hernias. Additionally, timely diagnosis and opportune hernia surgery using video-assisted thoracoscopic mesh repair can prevent further complications.

Abstract In Argentina, hemolytic uremic syndrome (HUS) caused by Shiga toxin-producing Escherichia coli (STEC-HUS) infection is endemic, and reliable data about prevalence and risk factors have been available since 2000. However, information about STEC-associated bloody diarrhea (BD) is limited. A prospective study was performed during the period October Surveillance; 2018-June 2019 in seven tertiary-hospitals and 18 referral units from different regions, aiming of STEC-HUS cases in the same hospitals and during the same period were also assessed. Twenty-nine (4.1%) of the BD patients were STEC-positive, as determined by the Shiga Toxin Quik Chek (STQC) test and/or the multiplex polymerase chain reaction (mPCR) assay. The highest fre-quencies were found in the Southern region (Neuquén, 8.7%; Bahía Blanca, 7.9%), in children between 12 and 23 month of age (8.8%), during summertime. Four (13.8%) cases progressed to HUS, three to nine days after diarrhea onset. Twenty-seven STEC-HUS in children under 5 years of age (77.8%) were enrolled, 51.9% were female; 44% were Stx-positive by STQC and all by mPCR. The most common serotypes were O157:H7 and O145:H28 and the prevalent geno-types, both among BD and HUS cases, were sfx2a-only or -associated. Considering the endemic behavior of HUS and its high incidence, these data show that the rate of STEC-positive cases is low among BD patients. However, the early recognition of STEC-positive cases is important for patient monitoring and initiation of supportive treatment.

Resumen En Argentina, el síndrome urémico hemolítico asociado a Escherichia coli productor de toxina Shiga (STEC-SUH) es endémico y, desde 2000, de notificación obligatoria. Sin embargo, la información sobre diarrea sanguinolenta (DS) asociada a STEC (DS-STEC) es limitada. Se realizó un estudio prospectivo desde octubre de 2018 hasta junio de 2019 en siete hospitales de tercer nivel y 18 unidades de referencia de diferentes provincias argentinas, con el objetivo de determinar la frecuencia de casos de DS-STEC en 714 niños de 1 a 9 años que tuvieron DS (I) y la tasa de progresión de DS a SUH en dicha cohorte (II). También se evaluó el número y distribución regional de casos de STEC-SUH en los mismos hospitales en dicho período. Veintinueve casos de DS (4,1%) fueron STEC-positivos, determinados por Shiga Toxin Quik Chek (STQC) o PCR múltiple (mPCR). Las frecuencias más altas se encontraron en el sur del área relevada (Neuquén, 8,7%; Bahía Blanca, 7,9%), en niños de 12 a 23 meses (8,8%), en verano. Cuatro casos de DS-STEC (13,8%) progresaron a SUH, de tres a nueve días después del inicio de la diarrea. Se registraron 27 niños con STEC-SUH, estos fueron mayoritariamente <5 anos (77,8%) del sexo femenino (51,9%). El 44% de estos casos fueron Stx-positivos por STQC y todos por mPCR. Los serotipos más comunes fueron O157:H7y O145:H28, y el genotipo predominante fue stx2a, solo o asociado, en DS y SUH. Considerando el comportamiento endémico del SUH y su alta incidencia, estos datos muestran que la tasa de casos de DS-STEC es baja. Sin embargo, su reconocimiento temprano es importante para el seguimiento e inicio del tratamiento de sostén.

ABSTRACT. The crustacean hyperglycemic hormone (CHH) is a multifunctional neuropeptide that plays a central role in crustacean metabolism and physiology. Experiments were conducted to examine the metabolic and osmoionic capabilities of the white shrimp Penaeus vannamei injected with its recombinant CHH-A (rCHHA) peptide and acutely transferred from iso- (26 ppt) to hypo- (10 ppt) and hyper-osmotic (40 ppt) conditions. Hemolymph glucose, protein, osmoregulatory capacity (OC), and ionoregulatory capacity (IC) for sodium, chloride, potassium, and calcium were evaluated at four post-injection times (0.5, 1, 2, and 24 h). The rCHH-A peptide had hyperglycemic activity in all salinity conditions, obtaining maximum values at 1 h post-injection. However, in shrimp transferred to hyper-osmotic condition, rCHH-A caused the most significant reductions in OC (2 h), chloride IC (2 h), and total proteins (0.5-2 h) compared to the phosphate-buffered saline (PBS) control. Contrastingly, in shrimp transferred to hypo-osmotic conditions, rCHH-A decreased OC significantly from 2-24 h, strongly decreased chloride and potassium IC at 1 h post-injection, and increased total protein concentration in the hemolymph (1-2 h) when compared to PBS control. Concerning calcium, the rCHH-A injection decreased calcium IC at 10 ppt (1 h) and 26 ppt (2 h), providing insight into a potential role for CHHA in calcium regulation. The results suggest that glucose and protein mobilization could enhance energy for osmo-ionic regulation under extreme osmotic conditions. This research study contributed to understanding crustacean endocrinology in P. vannamei and related euryhaline crustaceans. Further research should be performed to understand the osmo- and ionoregulatory mechanisms of the different CHH variants in crustaceans exposed to other stress conditions and the relationship with intermediary energy metabolism regulation.

ABSTRACT Introduction: Cardiovascular diseases are the main cause of death due to non-communicable diseases. The detection of modifiable cardiovascular risk factors plays an important role in the prevention of cardiovascular morbidity and mortality. Objectives: To describe the frequency of modifiable cardiovascular risk factors in health career students at the Polytechnic and Artistic University of Paraguay, San Lorenzo branch. Methodology: Observational, descriptive, cross-sectional design. The data was obtained by a telematic survey during the year 2022. Result: One hundred thirty-four students participated, with a predominance of women: 104 (78%) with an average age of 25 ± 7 years, most of them were from the medical career 44 (33%). The cardiovascular risk factors found were: sedentary lifestyle in 83 (62%) participants, unhealthy eating habits in 128 (95%), smoking in 7 (5%), arterial hypertension in 7 (5%), type 2 diabetes mellitus in 3 (2%), and dyslipidemia in 4 (3%). There was loss of data for BMI in 62 cases, so the frequency of overweight or obesity has not been analyzed. The sample studied presented at least 1 cardiovascular risk factor in 131 participants (98%). The sum of cardiovascular risk factors per subject shows a high percentage of 42.5% and 39.5% for 2 and 3 associated risk factors, respectively. Conclusion: In the studied sample, despite being young and in training in health matters, there is a high frequency of at least one modifiable cardiovascular risk factor. The most frequent cardiovascular risk factors were unhealthy eating habits and a sedentary lifestyle. It is striking that, despite being a young population, hypertension, diabetes, and dyslipidemia are already present, assuming a high and early burden of cardiovascular risk.

La detección de los factores de riesgo cardiovascular modificables juega un rol importante en la prevención de la morbimortalidad cardiovascular. Objetivos: describir la frecuencia de factores de riesgo cardiovascular modificables en estudiantes de carreras de salud en la Universidad Politécnica y Artística del Paraguay, filial San Lorenzo. Metodología: diseño observacional, descriptivo, de corte trasversal. Los datos fueron obtenidos por una encuesta telemática durante el año 2022. Resultado: participaron 134 estudiantes, con predomino de mujeres: 104 (78%) con edad promedio de 25 ± 7 años, mayoría de la carrera de medicina 44 (33%). Los factores de riesgo cardiovascular encontrados fueron: sedentarismo en 83 (62%) participantes, hábito alimentario no saludable en 128 (95%), tabaquismo en 7 (5%), hipertensión arterial en 7 (5%), diabetes mellitus tipo 2 en 3 (2%), dislipidemia en 4 (3%). Hubo pérdida de datos para IMC en 62 casos, por lo que no se ha analizado la frecuencia de sobrepeso ni obesidad. La muestran estudiada presentó al menos 1 factor de riesgo cardiovascular 131 participantes (98%). La sumatoria de factores de riesgo cardiovascular por sujeto, muestra alto porcentaje 42,5% y 39,5% para 2 y 3 factores de riesgo asociados, respectivamente. Conclusión: en la muestra estudiada, a pesar de ser jóvenes y en formación en materias de salud, existe una alta frecuencia de al menos un factor de riesgo cardiovascular modificable. Los factores de riesgo cardiovascular más frecuentes fueron el hábito alimentario no saludable y sedentarismo. Llama la atención que a pesar de ser una población joven, la hipertensión, diabetes y dislipidemia ya se encuentran presentes suponiendo una carga alta y precoz de riesgo cardiovascular.

Resumen Objetivo: evaluar la prevalencia de la hipovitaminosis D en pacientes en hemodiálisis (HD) y su relación con el estado nutricional y la calidad de vida (CV). Material y métodos: un total de 120 pacientes fueron incluidos. La escala de Malnutrición-Inflamación (MIS) se utilizó para la detección del riesgo nutricional. La CV fue evaluada por el cuestionario Kidney Disease Quality of Life versión 1.2 (KDQOL-SF). Los pacientes fueron estratificados en tres grupos de acuerdo con el estado de la vitamina D: suficiencia (≥ 30 ng/dl), insuficiencia (29-10 ng/dl) y deficiencia (< 10 ng/dl) Resultados: se observó hipovitaminosis D en el 71 % de los pacientes. El análisis de regresión lineal múltiple mostró que la deficiencia de vitamina D fue el predictor más significativo de peores resultados en el cuestionario KDQOL-SF. La deficiencia de 25(OH)D explicó el 21 % de la varianza en el componente sumatorio de la enfermedad renal, el 27 % en el componente sumatorio físico y el 22 % en el componente sumatorio mental. Cuando evaluamos el estado nutricional, el análisis de regresión logística multivariante mostró que solo la deficiencia de vitamina D presenta un efecto significativo en la desnutrición (OR: 14.6, p < 0,001). Conclusión: de nuestros hallazgos concluimos que la hipovitaminosis D es muy frecuente entre los pacientes en HD y que su deficiencia está asociada un deterioro del estado nutricional y peor percepción de la calidad de vida.

Abstract Objective: to assess the prevalence of hypovitaminosis D in patients undergoing haemodialysis (HD) and to determine its relationship with nutritional status and quality of life (QoL). Material and methods: 120 patients were included in the study. The Malnutrition-Inflammation Score (MIS) was used to detect nutritional risk. QoL was evaluated by Kidney Disease Quality of Life version 1.2 (KDQOL-SF). Patients were stratified into three groups according to their vitamin D status: sufficiency (≥ 30 ng/dl), insufficiency (29-10 ng/dl) and deficiency (< 10 ng/dl). Results: hypovitaminosis D was detected in 71 % of the patients studied. Multiple linear regression analysis showed that vitamin-D deficiency was the most significant predictor of low KDQOL-SF scores. It explained 21 % of the variance in the Kidney Disease Component Summary, 27 % of that in the Physical Component Summary, and 22 % of that in the Mental Component Summary. Multiple logistic regression analysis showed that only vitamin-D deficiency was significantly associated with malnutrition (OR, 14.6, p < 0.001). Conclusion: HD patients frequently present with hypovitaminosis D. There is a significant correlation between vitamin-D deficiency, poorer nutritional status, and worse QoL in dialysed patients.

Resumen Estudiamos los factores de consumo de vino en las rutas enológicas del Centro de México. Para ello, diseñamos un cuestionario aplicado a 402 sujetos en la Ruta del Queso y el Vino, en Querétaro, estructurado en tres secciones: Food Choice Questionnaire para identificar los motivos de consumo, libre asociación de palabras y, finalmente, fueron recopiladas las características sociodemográficas, siendo estas últimas analizadas de manera cualitativa. Con la información recabada se realizó un Análisis Factorial Exploratorio y posteriormente un Análisis Jerárquico de Clúster, así como pruebas no paramétricas para identificar las diferencias estadísticas. Las palabras se analizaron mediante nubes de palabras. Dentro de los resultados, se identificaron 12 motivos de consumo, 14 categorías, ocho dimensiones y tres grupos de consumidores de vino en México en el contexto de la actividad enoturística. Concluimos que el consumo de vino está determinado y configurado por el nivel de relación existente entre el consumidor y referente cultural de la bebida. Además, hay un incremento en el interés del mexicano por consumir vino, adaptándolo a sus particularidades socioculturales y económicas.

Abstract The aim of this article is to study the factors of wine consumption in the oenological routes of Central Mexico. A questionnaire applied to 402 subjects was designed on the Cheese and Wine route, in Querétaro. It was structured in three sections: the Food Choice Questionnaire to identify the reasons for consumption, free word association, and finally, the sociodemographic characteristics were collected, the latter being analyzed qualitatively. With the information collected, an Exploratory Factor Analysis was carried out, and subsequently a Hierarchical Cluster Analysis; as well as non-parametric tests to identify statistical differences. The words were analyzed using word clouds. Within the results, 12 reasons for consumption, 14 categories, eight dimensions and three groups of wine consumers were identified in Mexico in the context of wine tourism activity. It is concluded that the consumption of wine is determined and configured by the level of relationship between the consumer and the cultural reference of the drink. In addition, there is an increase in Mexican interest in consuming wine, adapting it to their socio-cultural and economic particularities.

RESUMEN En general, los medios de comunicación y los boletines meteorológicos informan sobre el índice ultravioleta (UVI) para prevenir la sobreexposición al sol. Sin embargo, esta información no refleja el daño acumulado en la piel inducido por la cantidad total de UVR (radiación ultravioleta por sus siglas en inglés) acumulada en el tiempo, conocida como dosis eritematosa (ED). Este estudio analizó el UVI y el ED medidos a ±30 y ±60 minutos alrededor del mediodía solar (SN) en Arica, Norte de Chile. Los resultados muestran que SN ED superó la Mínima Dosis Eritematosa (MED por sus siglas en inglés) para todos los tipos de piel. Durante el verano, las exposiciones cortas a la luz solar de hasta 1 hora pueden resultar en una exposición solar hasta 10 veces mayor que el límite de seguridad ocupacional aceptable para la piel humana sin protección.

ABSTRACT News media and meteorological bulletins generally report on the ultraviolet index (UVI) to prevent overexposure to the sun. However, this information does not reflect the accumulated damage to the skin induced by the total amount of UVR (ultraviolet radiation) accumulated over time, known as erythemal dose (ED). This study analyzed the UVI and ED measured at ±30 and ±60 minutes around solar noon (SN) in Arica, North of Chile. The results show that SN ED exceeded the Minimum Erythema Dose (MED) for all the skin types. During the summer, shorts exposures to sunlight for up to 1 hour may result in sun exposure up to 10 times greater than the acceptable occupational safe limit for unprotected human skin.

Abstract In this paper, we present an attention classification method using Machine-Learning Algorithms. The EEG signals were recorded from ten engineering students with an EPOC+BCI using the electrodes F3, F4, P7, and P8 while solving some mathematical operations. The recording time for these activities is around 20 minutes. Next, a similar time EEG register is obtained while doing non-academic activities, such as chattering with the staff, checking cell phones, or playing a video game. With these EEG registers, we obtained a set of features to train and evaluate attention using Machine Learning algorithms. This research shows how engineering students interact with math topics in solving mental operations and complex reasoning by increasing brain domain and knowledge for mathematical reasoningrelated processes, such as sustained and shifting attention and logical constructions for object interaction during operations resolution. The Random Forest algorithm (RF) obtained the highest accuracy with 0.7392, an F1 Score of 0.7430, and the highest Specificity/Accuracy with 0.7261.

Resumen Se presenta un método de clasificación de la atención utilizando algoritmos de aprendizaje automático. Con las señales EEG de diez estudiantes de ingeniería adquiridas utilizando los electrodos F3, F4, P7 y P8 de una BCI EPOC+ mientras resuelven productos escalares, multiplicaciones algebraicas simples, simplificaciones e integrales por aproximadamente 20 minutos. Posteriormente, se obtiene un registro EEG de tiempo similar mientras se realizan actividades no académicas, como charlar con el personal, consultar el móvil o jugar a un videojuego. Se obtienen algunas características/parámetros, se entrenan y evalúan varios algoritmos de aprendizaje automático para la clasificación de la atención. Los resultados de esta investigación pueden mejorar la forma en que los estudiantes de ingeniería interactúan con los temas matemáticos en la resolución de operaciones mentales y razonamientos complejos, aumentando el dominio y el conocimiento cerebral para los procesos relacionados con el razonamiento matemático, como la atención sostenida y cambiante y las construcciones lógicas para la interacción con objetos durante la resolución de operaciones. El clasificador Random Forest obtuvo la mayor precisión con 0.7392, una puntuación F1 de 0.7430 y la mayor especificidad/precisión con 0.7261.

Resumen La Altillanura es un ecosistema único de los Llanos colombianos, caracterizado por sabanas bien drenadas y grandes extensiones de bosques ribereños. La Altillanura alberga ricas comunidades poco estudiadas y actualmente amenazadas por la agroindustria a gran escala y no planificada. Además, el número de áreas protegidas públicas en la Altillanura no es suficiente para conservar los hábitats y especies amenazados. Por lo tanto, los esfuerzos de las reservas privadas son cruciales para la conservación de la biodiversidad de la región. Presentamos el primer listado de especies del Tomogrande, reserva natural privada y estación de investigación científica en el municipio de Santa Rosalía, Vichada, Colombia. Después de diez años de investigación en curso, hemos registrado 299 especies de plantas, 189 especies de aves y 47 especies de mamíferos. En comparación con otras reservas naturales privadas en Vichada y con el Parque Nacional Tuparro, el área protegida más grande de la región, Tomogrande hace una contribución sustancial a la conservación de los tres grupos taxonómicos. Abogamos por una mejor planificación del paisaje y que prácticas sostenibles sean obligatorias en la Altillanura, a fin de proteger su biodiversidad y los medios de vida de todos los actores que habitan esta región.

Abstract The Altillanura is a unique ecosystem within the Colombian Llanos, characterized by well-drained savannas and extensive riparian forests. The Altillanura harbors a rich assemblage of species, largely understudied and currently under threat by large-scale and unplanned agribusiness. Moreover, the number of public protected areas in the Colombian Llanos, particularly in the Altillanura, is insufficient to conserve the threatened habitats and species. Therefore, conservation efforts by private reserves are crucial for the protection of the region’s biodiversity. Here we present the first species list of the Tomogrande, a private nature reserve and scientific research field station in the municipality of Santa Rosalía, Vichada, Colombia. After ten years of ongoing research, we have recorded 299 species of plants, 189 species of birds, and 47 species of mammals. Compared to other private nature reserves in Vichada and the Tuparro National Park, the largest protected area in the region, Tomogrande makes a substantial contribution to the conservation of all three taxonomic groups. We advocate that better landscape planning and sustainable practices should become mandatory in the Altillanura to protect its biodiversity and the livelihoods of all stakeholders that inhabit this region.

Resumen Introducción: La carga cognitiva determina la capacidad que tendrá la memoria de trabajo para almacenar y grabar información en la memoria a largo plazo, lo cual condiciona el aprendizaje. Objetivo: Comparar la carga cognitiva entre las distintas actividades de simulación, incluyendo talleres de simulación de anestesiología y cirugía en estudiantes de medicina. Métodos: Estudio observacional analítico tipo corte transversal. Se aplicaron dos escalas de medición de la carga cognitiva (Paas y NASA-TLX) a los estudiantes después de cada taller de simulación. Se realizaron comparaciones de los puntajes obtenidos mediante las escalas. Resultados: Se encontraron diferencias relevantes en cuanto al esfuerzo mental evaluado por la escala de Paas, en relación con el orden de rotación de los estudiantes en el taller de manejo de vía aérea; se encontró mayor esfuerzo en el grupo que rotó primero por cirugía (6,19 vs. 5,53; p = 0,029). El taller con mayores índices de frustración fue el de manejo de vía aérea. Este taller mostró los mayores puntajes en todos los ítems en la escala NASA-TLX, lo que indica una mayor carga cognitiva respecto a los demás. Conclusión: No fue posible diferenciar si los puntajes altos en algunas de las actividades se debieron a la dificultad natural del manejo de vía aérea, o al diseño específico del taller. Por lo que se requieren nuevos estudios que diferencien estos componentes para mejorar el diseño de actividades de aprendizaje.

Abstract Introduction: Cognitive load determines working memory ability to store and retain information in long-term memory, thus conditioning learning. Objective: To compare cognitive loads among different simulation activities, including anesthesia and surgery simulation workshops in medical students. Methods: Cross-sectional analytical observational study. Two cognitive load measurement scales (Paas and NASA-TLX) were given to the students after each simulation workshop. Comparisons were made based on the scores derived from the scales. Results: Relevant differences were found in terms of the mental effort assessed by means of the Paas scale, as relates to student rotation order in the airway management workshop, with a greater effort being found in the group that rotated initially in surgery (6.19 vs. 5.53; p = 0.029). The workshop with the highest associated rate of frustration was the airway management workshop. Higher scores were obtained for this workshop in all the items of the NASA-TLX scale, reflecting a higher cognitive load when compared to the others. Conclusions: It was not possible to determine whether higher scores in some of the activities were associated with the inherent difficulty of airway management or the specific workshop design. Consequently, further studies are required to distinguish between those components in order to improve the way learning activities are designed.

Abstract The objectives of this study were to determine the performance of the BCID panel and to establish the impact of these results on the antimicrobial treatment of patients with bacteremia in 11 hospitals in Latin America. Three hundred and ninety-seven episodes of bacteremia were included and 551 microorganisms isolated from blood cultures were documented. Microbial identification was correct in 91.4% (504/551) of the isolates and in 98.6% (504/511) if only the microorganisms included in the BCID panel are considered. The sensitivity in the detection of the genes mecA, vanA/B and blaKPC was 100% and the specificity was 97%, 100% and 99.6% respectively. Early notification of the outcome allowed therapeutic changes in 242 episodes (60.9%). The BCID panel is a reliable and rapid method for the detection of critical resistance mechanisms and of the microorganisms most frequently isolated from bacteremia and it enables early optimisation of antimicrobial treatment.

ABSTRACT This special report compares the measurement of primary health care (PHC) expenditure proposed by the Organization for Economic Cooperation and Development (OECD) and by the World Health Organization (WHO), according to the global framework for reporting health expenditures (SHA 2011) in three countries in the Region of the Americas. There are conceptual differences: (1) operationalization as basic care, by OECD, versus first contact, by WHO; (2) a wider range of goods and services in the WHO definition (including medicines, administration, and collective preventive services); and (3) consideration only of services in outpatient providers by OECD. PHC expenditures as a percentage of current healthcare spending in 2017 for WHO and OECD: Mexico (43.6% vs. 15.1%); Dominican Republic (41.1% vs. 5.75%), and Costa Rica (31.4% vs. 5.7%). The broad WHO definition of PHC as first contact facilitates inclusion of services that reflect the way countries provide care to their populations. Even so, WHO could improve its category descriptions for the purposes of international comparison. Restricting PHC to outpatient providers (as the OECD does) greatly limits measurement and excludes interventions intrinsic to the concept of PHC, such as collective preventive services. As a transitional step, we recommend that countries should monitor PHC funding and should explain what they include in their definition. SHA 2011 makes it possible to identify and compare these differences.

RESUMO Este informe especial apresenta uma comparação entre a medida do gasto em atenção primária à saúde (APS) conforme as propostas da Organização para a Cooperação e o Desenvolvimento Econômico (OCDE) e da Organização Mundial da Saúde (OMS), usando a metodologia mundialmente aceita para reportar gastos em saúde – o System of Health Accounts (SHA 2011) – em três países da Região das Américas. Observam-se divergências conceituais entre os métodos: 1) operacionalização do conceito como atenção básica pela OCDE ou primeiro contato pela OMS; 2) maior abrangência de bens e serviços de acordo com a definição da OMS (englobando medicamentos, administração e serviços de prevenção em âmbito coletivo) e 3) inclusão exclusivamente de serviços ambulatoriais de acordo com a OCDE. Os gastos em APS como percentual do gasto corrente em saúde (GCS) em 2017, de acordo com os métodos propostos pela OMS e pela OCDE, foram: 43,6% vs. 15,1% no México; 41,1 vs. 5,75% na República Dominicana; e 31,4% vs. 5,7% na Costa Rica. A definição ampla de APS como primeiro contato proposta pela OMS permite incluir os diferentes arranjos de atenção existentes nos países. No entanto, as categorias deveriam ser mais bem detalhadas para facilitar a comparação internacional. Por outro lado, a proposta da OECD restringe a APS aos prestadores de serviços ambulatoriais, o que limita muito a medição e exclui intervenções próprias do conceito de APS, como serviços de prevenção no âmbito coletivo. Numa etapa de transição, recomenda-se aos países monitorar o financiamento da APS, explicitando os itens incluídos na definição empregada. A metodologia SHA 2011 possibilita identificar e comparar essas diferenças.

RESUMEN En este informe especial se compara la medición del gasto en atención primaria en salud (APS) propuesta por la Organización para la Cooperación y el Desarrollo Económico (OCDE) y la Organización Mundial de la Salud (OMS) según el marco mundial para reportar gastos en salud (SHA 2011) en tres países de la región de las Américas. Hay divergencias conceptuales: 1) la operacionalización como atención básica, por OCDE, o primer contacto, por OMS; 2) la mayor amplitud de bienes y servicios en la definición de OMS (incluye medicamentos, administración y servicios preventivos colectivos); 3) la consideración únicamente de servicios en proveedores ambulatorios en OCDE. Los gastos en APS como el porcentaje del gasto corriente en salud (GCS) en 2017 para OMS y OCDE, serían: México (43,6% vs 15.1%); República Dominicana (41,1 vs 5,75%) y Costa Rica (31,4% vs 5,7%).La definición amplia de APS como primer contacto de OMS facilita la inclusión de servicios que reflejan la forma en que los países ofrecen atención a su población. Aun así, la OMS podría mejorar las descripciones de las categorías incluidas para fines de comparación internacional. Restringir la APS a proveedores ambulatorios como hace OCDE limita mucho la medición y excluye intervenciones intrínsecas al concepto de APS, como servicios colectivos de prevención. Como paso transitorio se recomienda a los países que monitoreen el financiamiento de la APS, explicitando qué incluyen en su definición. El SHA 2011 permite identificar y comparar estas diferencias.
