RESUMO
OBJECTIVE: To evaluate the predictive ability of mortality prediction scales in cancer patients admitted to intensive care units (ICUs). DESIGN: A systematic review of the literature was conducted using a search algorithm in October 2022. The following databases were searched: PubMed, Scopus, Virtual Health Library (BVS), and Medrxiv. The risk of bias was assessed using the QUADAS-2 scale. SETTING: ICUs admitting cancer patients. PARTICIPANTS: Studies that included adult patients with an active cancer diagnosis who were admitted to the ICU. INTERVENTIONS: Integrative study without interventions. MAIN VARIABLES OF INTEREST: Mortality prediction, standardized mortality, discrimination, and calibration. RESULTS: Seven mortality risk prediction models were analyzed in cancer patients in the ICU. Most models (APACHE II, APACHE IV, SOFA, SAPS-II, SAPS-III, and MPM II) underestimated mortality, while the ICMM overestimated it. The APACHE II had the SMR (Standardized Mortality Ratio) value closest to 1, suggesting a better prognostic ability compared to the other models. CONCLUSIONS: Predicting mortality in ICU cancer patients remains an intricate challenge due to the lack of a definitive superior model and the inherent limitations of available prediction tools. For evidence-based informed clinical decision-making, it is crucial to consider the healthcare team's familiarity with each tool and its inherent limitations. Developing novel instruments or conducting large-scale validation studies is essential to enhance prediction accuracy and optimize patient care in this population.
RESUMO
Appropriateness is a dimension of quality that evaluates the effective use of technologies, resources or interventions in specific situations or populations, assessing whether our interventions do more benefit than harm. The evidence regarding pain monitoring in the critically ill patient points to the periodic assessment of pain using appropriate tools, with the aim of improving pain management and more efficient use of analgesics in the intensive care unit. The first step would be to assess the patient's ability to communicate or self-report and, based on this, to select the most appropriate pain assessment tool. In patients who are unable to self-report, behavioural pain assessment tools are recommended. When we talk about the suitability of behavioural scales for pain monitoring in critically ill patients unable to self-report, we refer to their use with a clear clinical benefit, i.e. using the right tool for pain assessment to be effective, efficient and consistent with bioethical principles. To our knowledge, there are no published data on the suitability of pain assessment tools in unable to self-report critically ill patients, so, in the framework of continuous quality improvement in pain care, new research should incorporate this approach by integrating the best scientific evidence with current clinical practice.

INTRODUCTION AND OBJECTIVES: Stroke and bleeding risks in atrial fibrillation (AF) are often assessed at baseline to predict outcomes years later. We investigated whether dynamic changes in CHA2DS2-VASc and HAS-BLED scores over time modify risk prediction. METHODS: We included patients with AF who were stable while taking vitamin K antagonists. During a 6-year follow-up, all ischemic strokes/transient ischemic attacks (TIAs) and major bleeding events were recorded. CHA2DS2-VASc and HAS-BLED were recalculated every 2-years and tested for clinical outcomes at 2-year periods. RESULTS: We included 1361 patients (mean CHA2DS2-VASc and HAS-BLED 4.0±1.7 and 2.9±1.2). During the follow-up, 156 (11.5%) patients had an ischemic stroke/TIA and 269 (19.8%) had a major bleeding event. Compared with the baseline CHA2DS2-VASc, the CHA2DS2-VASc recalculated at 2 years had higher predictive ability for ischemic stroke/TIA during the period from 2 to 4 years. Integrated discrimination improvement (IDI) and net reclassification improvement (NRI) showed improvements in sensitivity and better reclassification. The CHA2DS2-VASc recalculated at 4 years had better predictive performance than the baseline CHA2DS2-VASc during the period from 4 to 6 years, with an improvement in IDI and an enhancement of the reclassification. The recalculated HAS-BLED at 2-years had higher predictive ability than the baseline score for major bleeding during the period from 2 to 4 years, with significant improvements in sensitivity and reclassification. A slight enhancement in sensitivity was observed with the HAS-BLED score recalculated at 4 years compared with the baseline score. CONCLUSIONS: In AF patients, stroke and bleeding risks are dynamic and change over time. The CHA2DS2-VASc and HAS-BLED scores should be regularly reassessed, particularly for accurate stroke risk prediction.
RESUMO
BACKGROUND AND OBJECTIVE: The Simplified Psoriasis Index (SPI) is a recently validated tool in Spanish that measures psoriasis severity by integrating 3 different spheres: clinical severity (SPI-s), psychosocial impact (SPI-p), and natural history (SPI-i). Our objective was to study the validity and equivalence of this new scale compared to routinely used scales such as the Psoriasis Area and Severity Index, PASI, and the Dermatology Life Quality Index (DLQI). MATERIALS AND METHODS: This was a cross-sectional and observational study that included 45 patients aged 18 to 74 years. Demographic data and information associated with psoriasis severity and the patients' quality of life were collected, using PASI, DLQI, and SPI simultaneously. The correlation of reference scales (PASI and DLQI) with SPI was examined. The degree of agreement between the 2 versions of SPI completed by the physician (proSPI-s) and self-administered by the patient (saSPI-s), was also studied. RESULTS: The mean age of the study population was 51 years, with a mean psoriasis history of 14.05 years. A strong correlation was found between PASI and proSPI-s (r=0.89), as well as between DLQI and SPI-p (r=0.89), with a moderate correlation being reported between PASI and saSPI-s (r=0.52). The degree of agreement between proSPI-s and saSPI-s was moderate. CONCLUSIONS: These findings represent the initial results of real clinical practice using the validated Spanish version of SPI, making its use truly promising in the routine clinical practice.
RESUMO
OBJECTIVE: To analyze the prognostic accuracy of the scores NEWS, qSOFA, GYM used in hospital emergency department (ED) in the assessment of elderly patients who consult for an infectious disease. METHODS: Data from the EDEN (Emergency Department and Elderly Need) cohort were used. This retrospective cohort included all patients aged ≥65 years seen in 52 Spanish EDs during two weeks (from 1-4-2019 to 7-4-2019 and 30/3/2020 to 5/4/2020) with an infectious disease diagnosis in the emergency department. Demographic variables, demographic variables, comorbidities, Charlson and Barthel index and needed scores parameters were recorded. The predictive capacity for 30-day mortality of each scale was estimated by calculating the area under the receiver operating characteristic (ROC) curve, and sensitivity and specificity were calculated for different cut-off points. The primary outcome variable was 30-day mortality. RESULTS: 6054 patients were analyzed. Median age was 80 years (IQR 73-87) and 45.3% women. 993 (16,4%) patients died. NEWS score had better AUC than qSOFA (0.765, 95CI: 0.725-0.806, versus 0.700, 95%CI: 0.653-0.746; Pâ¯<â¯.001) and GYM (0.716, 95%CI: 0.675-0.758; Pâ¯=â¯.024), and there was no difference between qSOFA and GYM (Pâ¯=â¯.345). The highest sensitivity scores for 30-day mortality were GYMâ¯≥â¯1 point (85.4%) while the qSOFA score ≥2 points showed high specificity. In the case of the NEWS scale, the cut-off point ≥4 showed high sensitivity, while the cut-off point NEWSâ¯≥â¯8 showed high specificity. CONCLUSION: NEWS score showed the highest predictive capacity for 30-day mortality. GYM score ≥1 showed a great sensitivity, while qSOFA ≥2 scores provide the highest specificity but lower sensitivity.
RESUMO
Long covid is a health problem that will entail a high hidden cost attributable to the pandemic years after it because it affects the work capacity of many workers. Given the millions of covid-19 cases worldwide and current research showing that one in 7covid-19 patients remain symptomatic at 12 weeks, the number of long covid patients is likely to be substantial. Long covid is characterized by heterogeneous sequelae that often affect multiple systems, organs with an impact on the functioning and capacity of the worker. Workers with long covid symptoms can return to their occupation but this involves a complex individualized approach to the impact of symptoms on work, adjustments and modifications to the workplace. Patients with long covid typically report prolonged multisystem involvement and signicant disability. The psychological cost to the worker must also be addressed. A survey by the Community of Madrid (CCOO, SATSE, CSIF, AMYTS) in 2022 reveals that 24.5% of those affected by long covid were sick for more than 12 months; 30% of those affected by persistent covid need and adaption to their workplace. In Spain, more than 10million people infected with SARS-CoV-2 have been reported since the pandemic began, so it is estimated that there could be one million people with persistent covid. In 2021 alone there were more than 2.6 million sick leave due to covid-19 in Spain, the average duration of which was 10 days. One hundred million people around the world suffer from persistent covid, but few countries officially count them, nor do they help those affected with employment. In advanced countries, like the United States, long covid is treated as a disability,and the number of people with disabilities working or looking for work increased by 1.36 million, an increase of 23%, between January 2021 and January 2022. In the United Kingdom, some 200,000 people are not working or are not looking for work due to long-term health problems attributable to long covid, since the pandemic began.

PURPOSE: Update the list of medical acts in the specialty of Neurosurgery, eliminating obsolete acts and adding the new surgical techniques developed in recent years, so that they are faithfully adapted to the usual medical practice of our specialty, as well as establishing the general principles and defining the grading criteria, quantitative indicators and assessment scales. METHODS: The elaboration of the new nomenclator was divided into 3 phases: 1) identification and selection of medical acts, 2) establishment of the degree of difficulty of each of them based on the experience and the time necessary for their completion, as well as the percentage and severity of the possible complications and 3) consensus with the members of the SENEC through their individualized submission, making the necessary adjustments and subsequent approval in the general assembly of SENEC. RESULTS: The new nomenclator has 255 medical acts grouped into 4 groups: consultations and visits, therapeutic acts, diagnostic procedures and surgical interventions. 42 procedures included in the OMC nomenclator have been eliminated due to being obsolete, not related to the specialty or being too vague. New techniques have been included and medical acts have been more precisely defined. CONCLUSIONS: This nomenclator provides up-to-date terminology and will serve to offer the portfolio of services, measure and know the relative value of our activity and the approximate costs of the procedures, and additionally, to carry out longitudinal comparative studies. It should be a tool to improve patient care and minimise geographic variability in all healthcare settings.

INTRODUCTION: Multiple scales have been designed to stratify the severity and predict the prognosis in the initial evaluation of patients with aneurysmal subarachnoid hemorrhage (aSAH). Our study aimed to validate the most commonly used prognostic scales for aSAH in our population: Hunt-Hess, modified Hunt-Hess, World Federation of Neurosurgical Societies (WFNS), Prognosis on Admission of Aneurysmal Subarachnoid Hemorrhage (PAASH), and Barrow Aneurysm Institute (BAI) scales. METHODS: This study includes all aSAH cases treated at our institution between June 2019 and December 2020. We developed a retrospective cohort by reviewing medical records and radiologic images performed during hospitalization. The outcome was evaluated using the modified Rankin scale (mRS). It was defined as a poor outcome (mRS 4-5) and mortality (mRS 6). The ROC curves and the area under the curve (AUC) of each of the prognostic scales were calculated to evaluate their prognostic prediction capacity. RESULTS: A total of 142 patients were diagnosed with aSAH. A poor outcome occurred in 52.1% of the patients, whereas mortality was 27.5%. The AUC of the scales studied was similar and no significant difference was found between them for predicting a poor outcome (P = .709) or mortality (P = .715). CONCLUSION: We determined that the prognostic scales for aSAH had a similar predictive value for poor clinical outcomes and mortality in our institution, with no significant difference. Thus, we recommend the most simple and well-known scale used institutionally.

INTRODUCTION AND OBJECTIVES: Hypertension is the most prevalent risk factor globally. Calculation of cardiovascular risk in hypertensive patients before initiation of treatment is recommended. This study aimed to assess the predictive value and clinical utility of the SCORE scale in preventing cardiovascular events and all-cause mortality in patients with hypertension. METHODS: Patients with hypertension from the ESCARVAL-RISK cohort were included. Cardiovascular risk was calculated using the SCORE scale. All deaths and cardiovascular events were recorded during a 5-year follow-up period. Sensitivity, specificity and predictive values were calculated for different cut-off points and the effect of different risk factors on the diagnostic accuracy of SCORE charts were assessed. RESULTS: In a final cohort of 9834 patients, there were 555 cardiovascular events and 69 deaths. The recommended risk value for initiating drug treatment (5%) had a specificity of 92% for death and 91% for cardiovascular events, and a sensitivity of 20% for death and 22% for cardiovascular events. In addition, the scale classified 80.4% of patients who experienced a cardiovascular event and 78.3% of those who died as low risk. Age, body mass index, retinopathy and anticoagulant therapy were associated with reduced predictive ability of the SCORE scale, while being female was associated with better risk prediction. CONCLUSIONS: The predictive ability of the SCORE scale for cardiovascular disease and total mortality in patients with hypertension is limited.

Al desarrollar modelos de predicción para su aplicación en la práctica clínica, los profesionales de la salud suelen categorizar las variables clínicas que son de naturaleza continua. En muchas ocasiones estos modelos constituyen la base para la confección de escalas predictivas, a partir de las cuales se estratifica a los pacientes en varias categorías atendiendo al fenómeno estudiado. En estos casos se requiere la determinación de uno o varios puntos de cortes que permitan dividir el recorrido de la variable, variables continuas o puntuaciones de una escala, en dos o más categorías. El presente trabajo tiene como objetivo la automatización de diferentes métodos para dicotomizar variables continuas en modelos de predicción clínica, donde la variable respuesta es dicotómica, y determinar el punto de corte óptimo en la estratificación de pacientes en dos categorías, a partir de escalas de predicción. Para ello se elaboró un software en el lenguaje de programación R, que implementa diferentes métodos para la determinación del punto de corte óptimo, lo cual agiliza el trabajo investigativo de los especialistas de salud en el proceso de elaboración de modelos predictivos y/o escalas de predicción.
When developing predictive models for application in clinical practice, health professionals often categorize clinical variables that are continuous in nature. In many cases, these models are the basis for the development of predictive scales from which patients are stratified into various categories according to the phenomenon under study. In both cases, it is necessary to determine one or more cut-off points that allow dividing the path of the variable, continuous variables, or scores of a scale into two or more categories. The aim of the present work is to automate different existing methods for dichotomizing continuous variables in clinical prediction models where the response variable is dichotomous, as well as to determine the optimal cut-off point for stratifying patients into two categories, based on prediction scales. For this purpose, a software was developed in the R programming language, which implements different existing methods for the determination of the optimal cut-off point, speeding up the research work of health specialists in the process of developing predictive models and/or prediction scales.
RESUMO
ABSTRACT Objective: To investigate the impact of delirium severity in critically ill COVID-19 patients and its association with outcomes. Methods: This prospective cohort study was performed in two tertiary intensive care units in Rio de Janeiro, Brazil. COVID-19 patients were evaluated daily during the first 7 days of intensive care unit stay using the Richmond Agitation Sedation Scale, Confusion Assessment Method for Intensive Care Unit (CAM-ICU) and Confusion Method Assessment for Intensive Care Unit-7 (CAM-ICU-7). Delirium severity was correlated with outcomes and one-year mortality. Results: Among the 277 COVID-19 patients included, delirium occurred in 101 (36.5%) during the first 7 days of intensive care unit stay, and it was associated with a higher length of intensive care unit stay in days (IQR 13 [7 - 25] versus 6 [4 - 12]; p < 0.001), higher hospital mortality (25.74% versus 5.11%; p < 0.001) and additional higher one-year mortality (5.3% versus 0.6%, p < 0.001). Delirium was classified by CAM-ICU-7 in terms of severity, and higher scores were associated with higher in-hospital mortality (17.86% versus 34.38% versus 38.46%, 95%CI, p value < 0.001). Severe delirium was associated with a higher risk of progression to coma (OR 7.1; 95%CI 1.9 - 31.0; p = 0.005) and to mechanical ventilation (OR 11.09; 95%CI 2.8 - 58.5; p = 0.002) in the multivariate analysis, adjusted by severity and frailty. Conclusion: In patients admitted with COVID-19 in the intensive care unit, delirium was an independent risk factor for the worst prognosis, including mortality. The delirium severity assessed by the CAM-ICU-7 during the first week in the intensive care unit was associated with poor outcomes, including progression to coma and to mechanical ventilation.
RESUMO Objetivo: Investigar como a gravidade do delirium afeta pacientes graves com COVID-19 e sua associação com os desfechos. Métodos: Estudo de coorte prospectivo realizado em duas unidades de terapia intensiva terciárias no Rio de Janeiro (RJ). Os pacientes com COVID-19 foram avaliados diariamente durante os primeiros 7 dias de internação na unidade de terapia intensiva usando a escala de agitação e sedação de Richmond, a Confusion Assessment Method for Intensive Care Unit (CAM-ICU) e a Confusion Assessment Method for Intensive Care Unit-7 (CAM-ICU-7). A gravidade do delirium foi correlacionada com os desfechos e a mortalidade em 1 ano. Resultados: Entre os 277 pacientes com COVID-19 incluídos, o delirium ocorreu em 101 (36,5%) durante os primeiros 7 dias de internação na unidade de terapia intensiva e foi associado a maior tempo de internação na unidade de terapia intensiva em dias (IQ: 13 [7 - 25] versus 6 [4 - 12]; p < 0,001), maior mortalidade hospitalar (25,74% versus 5,11%; p < 0,001) e maior mortalidade em 1 ano (5,3% versus 0,6%, p < 0,001). O delirium foi classificado pela CAM-ICU-7 em termos de gravidade, e escores maiores foram associados à maior mortalidade hospitalar (17,86% versus 34,38% versus 38,46%, IC95%, valor de p < 0,001). O delirium grave foi associado a um risco maior de progressão ao coma (RC de 7,1; IC95% 1,9 - 31,0; p = 0,005) e à ventilação mecânica (RC de 11,09; IC95% 2,8 - 58,5; p = 0,002) na análise multivariada, ajustada por gravidade e fragilidade Conclusão: Em pacientes internados com COVID-19 na unidade de terapia intensiva, o delirium foi fator de risco independente para o pior prognóstico, incluindo mortalidade. A gravidade do delirium avaliada pela CAM-ICU-7 durante a primeira semana na unidade de terapia intensiva foi associada a desfechos desfavoráveis, incluindo a progressão ao coma e à ventilação mecânica.
RESUMO
Introduction: Good bowel preparation is essential for a quality colonoscopy. Thus, evaluating the risk factors associated with poor preparation is necessary. This problem has not been widely addressed in Colombia. Aim: To identify the factors associated with poor intestinal preparation. Materials and methods: Observational, analytical, cross-sectional, multicenter study in patients > 18 years of age who underwent colonoscopy and attended gastroenterology services between January and June 2020 in Bogotá. A Boston scale > 6 was defined as good preparation, and a Boston scale ≤ 6 was defined as poor preparation. Results: 265 patients were included, of whom 205 (77.4%) were well prepared and 60 (22.6%) had inadequate preparation. Factors associated with poor bowel preparation were age older than 60 years (odds ratio [OR]: 1.359; 95% confidence interval [CI]: 1.059-1.745; p = 0.026); male sex (OR: 1.573; 95% CI: 1.128-2.194; p = 0.012); obesity (BMI > 30 kg/m2; OR: 2.539; 95% CI: 1.388-4.645; p = 0.002); constipation (OR: 1.924; 95% CI: 1.154-3.208; p = 0.014); the use of antidepressants (OR: 2.897; 95% CI: 1.199-6.997; p = 0.014) and calcium antagonists (OR: 2.445; 95% CI: 1.292-4.630; p = 0.005), and having abdominopelvic surgeries (OR: 1.325 95% CI: 1.042-1.684, p = 0.034). Regarding the procedure, there was less polyp detection per patient (p = 0.04) and less minute (p = 0.020) and flat (p = 0.047) polyp detection in the poor bowel preparation group. Conclusions: This is the first study in Colombia in which the factors associated with poor intestinal preparation are described and include variables not explored in other studies. The results found are similar to those reported in the literature. These studies should be promoted with more patients, establishing a score for predicting poor preparation.
Introducción: una buena preparación intestinal es fundamental para una colonoscopia de calidad. Por eso es importante evaluar los factores de riesgo asociados a una mala preparación. Este problema no se ha abordado ampliamente en Colombia, por lo cual el objetivo de este estudio es identificar los factores asociados a una mala preparación intestinal. Métodos: estudio observacional, analítico, transversal, multicéntrico en pacientes > 18 años sometidos a colonoscopia que asistieron a los servicios de gastroenterología entre enero y junio de 2020 en la ciudad de Bogotá. Se definió como buena preparación una escala de Boston > 6, y como mala preparación una escala de Boston ≤ 6. Resultados: se incluyeron a 265 pacientes, de los cuales 205 (77,4%) estaban bien preparados y 60 (22,6%) tenían una preparación inadecuada. Los factores asociados a mala preparación intestinal fueron edad mayor de 60 años (odds ratio [OR]: 1,359; intervalo de confianza [IC] del 95%: 1,059-1,745; p = 0,026); sexo masculino (OR: 1,573; IC 95%: 1,128-2,194; p = 0,012); obesidad (IMC > 30 kg/m2; OR: 2,539; IC 95%: 1,388-4,645; p = 0,002); estreñimiento (OR: 1,924; IC 95%: 1,154-3,208; p = 0,014); el uso de antidepresivos (OR: 2,897; IC 95%: 1,199-6,997; p = 0,014) y antagonistas del calcio (OR: 2,445; IC 95%:1,292-4,630; p = 0,005) y tener cirugías abdominopélvicas (OR: 1,325; IC 95%: 1,042-1,684; p = 0,034). En cuanto al procedimiento, hubo una menor cantidad de detección de pólipos por paciente (p = 0,04) y menor detección de pólipo diminuto (p = 0,020) y plano (p = 0,047) en el grupo de mala preparación intestinal. Conclusiones: este es el primer estudio en Colombia en el cual se describen los factores asociados a la mala preparación intestinal e incluye variables no exploradas en otros estudios. Los resultados encontrados son similares a los reportados en la literatura. Se debe impulsar este tipo de estudios con una mayor cantidad de pacientes y plantear un puntaje de predicción de mala preparación.
RESUMO
La anemia afecta a miles de niños. Para el diagnóstico se cuantifica la hemoglobina (Hb); técnica que no se encuentra al alcance de toda la población. Contar con un instrumento validado de fácil aplicación, puede ayudar al diagnóstico. El objetivo de este estudio fue validar una aplicación móvil (APP) para diagnosticar anemia en niños de 2 a 5 años, aplicable por padres o tutores. Estudio de validación de escalas. Mediante búsqueda bibliografía se recopilaron ítems y dominios relacionados con anemia en niños. Una vez reducidos, se construyó un cuestionario para pilotaje, con tres hematólogos pediatras. El resultado de este fue posteriormente validado por 22 expertos mediante aplicación de escalas tipo Likert. Los ítems validados, se contrastaron con la Hb de niños de 267 niños de 2 a 5 años de los andes ecuatorianos (2.560 msnm). Se determinó asociación de los ítems con Hb y con los resultados obtenidos y se construyó la APP. 14 ítems fueron analizados. Todos ellos puntuaron sobre la mediana de la distribución (35,5 puntos) y fueron valorados por, al menos el 50 % de los expertos. Se seleccionaron palidez palmar, astenia y sueño en horas no habituales. Todos mostraron asociación significativa con anemia (p<0,05), y fueron aplicados como preguntas a padres o tutores y contrastados con el valor de Hb. Sensibilidad y especificidad para palidez fue: 85,1 % y 85,0 %; astenia: 72,3 % y 87,7 %; sueño en horas no habituales: 68,1 % y 87,7 %; palidez más astenia o sueño: 95,7 % y 74,6 %; y debilidad más sueño: 92,5 % y 76,8 %. Se desarrolló y validó una APP para diagnóstico de anemia en niños de 2 a 5 años aplicable por padres o tutores.
SUMMARY: Anemia affects thousands of children, and to reach a diagnosis, hemoglobin (Hb) is quantified. This technique however, is not always accessible to the general population. Therefore, the availability of a validated instrument can be useful in the diagnosis. The aim of this study was to validate a mobile application (APP), to diagnose anemia in children from 2 to 5 years old, applicable by parents or guardians. Scale validation study. Through a bibliographic search, items and domains related to anemia in children were collected. Once reduced, a pilot questionnaire was constructed with three pediatric hematologists. The result was later validated by 22 experts through the application of the Likert-type scales. The validated items were contrasted with the Hb of children of 267 children from 2 to 5 years of age from the Ecuadorian Andes (2,560 meters above sea level). The association of the items with Hb and with the results obtained was determined, and the APP was constructed. 14 items were analyzed. All of them scored above the median of the distribution (35.5 points) and were valued by at least 50 % of the experts. Palmar pallor, asthenia, and sleep at unusual hours were selected. All showed a significant association with anemia (p<0.05) and were applied as questions to parents or guardians and contrasted with the Hb value. Sensitivity and specificity for pallor was: 85.1 % and 85.0 %; asthenia: 72.3 % and 87.7 %; sleep at unusual hours: 68.1 % and 87.7 %; paleness plus fatigue or sleepiness: 95.7 % and 74.6 %; and weakness plus sleep: 92.5 % and 76.8 %. An APP for the diagnosis of anemia in children from 2 to 5 years old applicable by parents or guardians was developed and validated.

Abstract The objective of this study was to compare three models: the theory of reasoned action (TRA), the theory of planned behavior (TPB), and its extended form (ETPB), to predict the intention of Chilean consumers for purchasing green products. Five hundred people were surveyed, establishing an inter-rater reliability analysis, and a discriminant, convergent and construct validity using three structural equation models (SEM). The results showed that the ETPB model is useful to explain the consumption behavior intention for green products based on a triple bottom line, whose main contribution is the indirect effect of EC on the model. The study found that of the three variables, PBC was the strongest predictor of purchase intention, followed by attitude. In conclusion, both the ETPB model and the green products purchase intention instrument contribute to broaden the studies about consumer behavior in sustainable marketing in Chile.
Resumen El objetivo del presente estudio fue comparar los modelos de teoría de acción razonada (TAR), teoría de comportamiento planificado (TCP) y su forma extendida (TCPE), para predecir la intención de compra de productos ecológicos en consumidores chilenos. Se encuestaron 500 personas y se estableció un análisis de fiabilidad interjuez, validez discriminante, convergente y de constructo a través de modelos de ecuaciones estructurales (SEM). Los resultados señalan que el modelo TCPE es útil para explicar la intención de comportamiento de consumo ante productos verdes con base en una triple línea de fondo, cuya principal contribución es el efecto indirecto de PA sobre el modelo. De las tres variables, se evidencia que el CCP era la predictora más fuerte de la intención de compra, seguida de la actitud. En conclusión, tanto el modelo TCPE como el instrumento de intención de compra de productos verdes contribuyen a la ampliación de estudios sobre el comportamiento del consumidor en marketing sustentable en Chile.

Capitán, C. y Aragón, L.F. (2023). La sed ¿un mecanismo suficiente para lograr euhidratación?: una revisión narrativa. PENSAR EN MOVIMIENTO: Revista de Ciencias del Ejercicio y la Salud, 21(1), 1-16. El papel de la percepción de sed para mantener el balance hídrico ha sido ampliamente estudiado, tanto durante el ejercicio como después de este. Sin embargo, la forma de evaluarla y la eficacia de los instrumentos existentes son aún áreas que necesitan más investigación. El objetivo de esta revisión fue integrar, de forma general, la información disponible en la literatura sobre el funcionamiento del mecanismo de la sed como respuesta a la deshidratación durante y después del ejercicio. Se explican los mecanismos fisiológicos y las respuestas de estos durante y posterior al ejercicio; además, se describen los instrumentos disponibles en la literatura científica, sus debilidades y fortalezas, y se plantea una serie de preguntas que aún no tienen respuesta en el área. En esta revisión se presenta el aspecto teórico de los mecanismos de la sed, además, se discuten los estudios científicos que respaldan o refutan el comportamiento de estos mecanismos en el ejercicio. Finalmente, se hace un resumen de las principales conclusiones extraídas de la literatura científica sobre la sed como un mecanismo suficiente para prevenir la deshidratación tanto durante como después del ejercicio.

The role of thirst perception for keeping hydric balance, both during and after exercise, has been extensively studied. However, the way to assess it and the effectiveness of the existing instruments are areas that still require further research. The objective of this review is to integrate, in a general way, the information available in the literature on the functioning of the thirst mechanism as a response to dehydration during and after exercise. The physiological mechanisms and their responses during and after exercise are explained. In addition, a description of the instruments available in scientific literature is included, together with their weaknesses and strengths, and a series of as yet unanswered questions in this area are raised. This review presents the theoretical aspect of thirst mechanisms, and discusses the scientific studies that support or refute the behavior of these mechanisms in exercise. Finally, a summary is made of the major conclusions drawn from the scientific literature on thirst as a sufficient mechanism to prevent dehydration both during and after exercise.

O papel da percepção da sede na manutenção do equilíbrio hídrico tem sido amplamente estudado, tanto durante quanto após o exercício. Entretanto, como avaliá-la e a eficácia dos instrumentos existentes ainda são áreas que necessitam de mais pesquisas. Esta revisão visou integrar, de forma geral, as informações disponíveis na literatura sobre o funcionamento do mecanismo da sede em resposta à desidratação durante e após o exercício. Ele explica os mecanismos fisiológicos e suas respostas durante e após o exercício, descreve os instrumentos disponíveis na literatura científica, seus pontos fracos e fortes, e levanta uma série de questões que permanecem sem resposta no campo. Esta revisão apresenta o aspecto teórico dos mecanismos da sede e discute os estudos científicos que respaldam ou refutam o comportamento desses mecanismos no exercício. Finalmente, é feito um resumo das principais conclusões extraídas da literatura científica sobre a sede como mecanismo suficiente para prevenir a desidratação tanto durante quanto após o exercício.

Resumen Objetivo. Analizar las propiedades psicométricas del AAQ-II en población adulta ecuatoriana con tomas presenciales, aumentando la fiabilidad de la muestra. Método. En este estudio se evaluaron las propiedades psicométricas de la Acceptance and Action Questionnaire-II (AAQ-II) en población ecuatoriana. Participaron 450 personas entre 18 y 53 años, de las cuales un 46.7% fueron mujeres y un 53.3% hombres. Resultados. En el análisis factorial confirmatorio se encontró una estructura de tres dimensiones: evitación de recuerdos, evitación emocional y falta de autodominio. Un análisis de invarianza reveló que la escala es invariante entre hombres y mujeres. Se encontró que la escala presenta buena consistencia interna (α = .90). Se discute la validez de la AAQ-II como una herramienta para evaluar la evitación experiencial en población adulta ecuatoriana.
Abstract Objective. To analyze AAQ-II psychometric properties on the Ecuadorian people. Method. In this study, the psychometric properties of the Acceptance and Action Questionnaire-II (AAQ-II) were evaluated in an Ecuadorian population. A total of 450 people between 18 and 53 years of age, 46.7% of whom were women, participated. Results. The confirmatory factor analysis found a three-dimensional structure: memory avoidance, emotional avoidance, and lack of self-control. An analysis of invariance between men and women revealed that the scale is invariant by sex. The scale was found to have good internal consistency (α = .90). The validity of the AAQ-II as a tool to assess experiential avoidance in an Ecuadorian adult population is discussed.

Discusión: Esta revisión integrativa proporciona a los profesionales de salud, y en especial al profesional de enfermería bases conceptuales para la implementación de herramientas de evaluación clínica del dolor, según la edad gestacional, la duración del dolor y el tipo de indicador. Conclusiones: De acuerdo al conocimiento y características de las escalas, no se puede establecer claramente la más adecuada para uso general o patrón de oro, la selección dependerá de diferentes criterios, como tipo de estímulo, la edad gestacional, y del contexto en el que se encuentra el recién nacido.
Introduction: Since infants are not able to express their feelings during the preverbal stage of development, neonatal pain rating scales are good tools for nurses to use in clinical practice. Objective: To describe valid and reliable scales used in nursing practice to assess neonatal pain. Materials and Methods: An integrative review of articles published since 1990 was conducted from 2019 to 2020. The databases consulted were PubMed, Lilacs, ProQuest, ScienceDirect, Embase, VHL, Scopus, and Google Scholar metasearch engine. Twenty-two articles that met the inclusion criteria were analyzed. Results: Unidimensional and multidimensional instruments were found for assessing acute and prolonged pain in preterm and term neonates. Discussion: This integrative review provides healthcare professionals, especially nurses, with a conceptual basis for implementing clinical pain assessment tools according to gestational age, duration of pain, and type of indicator. Conclusions: According to the knowledge and characteristics of the scales, it is not possible to clearly establish the most appropriate one for general use or a gold standard; the selection will depend on different criteria, such as the type of stimulus, gestational age, and the newborn's context.

RESUMO
OBJECTIVE: The COVID-19-12O-score has been validated to determine the risk of respiratory failure in patients hospitalized for COVID-19. Our study aims to assess whether the score is effective in patients with SARS-CoV-2 pneumonia discharged from a hospital emergency department (HED) to predict readmission and revisit. METHOD: Retrospective cohort of patients with SARS-CoV-2 pneumonia discharged consecutively from an HUS of a tertiary hospital, from January 7 to February 17, 2021, where we applied the COVID-19-12O -score, with a cut-off point of 9 points to define the risk of admission or revisit. The primary outcome variable was revisit with or without hospital readmission after 30 days of discharge from HUS. RESULTS: We included 77 patients, with a median age of 59 years, 63.6% men and Charlson index of 2. 9.1% had an emergency room revisit and 15.3% had a deferred hospital admission. The relative risk (RR) for emergency journal was 0.46 (0.04-4.62, 95% CI, p=0.452), and the RR for hospital readmission was 6.88 (1.20-39.49, 95% CI, p<0.005). CONCLUSIONS: The COVID-19-12O -score is effective in determining the risk of hospital readmission in patients discharged from HED with SARS-CoV-2 pneumonia, but is not useful for assessing the risk of revisit.

OBJECTIVES: To compare the ability of the Glasgow Coma Scale (GCS) score, the GCS Pupils (GCS-P) score, and the Pupil Reactivity Score (PRS) to predict mortality in patients with severe head injury. MATERIAL AND METHODS: Retrospective analysis of all patients with severe head injury and initial GCS scores of 8 or lower on initial evaluation for whom records included pupil dilation information and clinical course after admission to intensive care units of participating hospitals. We assessed the ability of each of the 3 scores (GCS, GCS-P, and PRS) to predict mortality using discrimination analysis. Discrimination was estimated by calculating the areas under the receiver operating characteristic curves (AUC) and 95% CIs. RESULTS: A total of 1551 patients with severe head injury and pupil dilation records were studied. The mean age was 50 years, 1190 (76.7%) were males, and 592 (38.2%) died. No pupil dilation was observed in 905 patients (58.3%), 362 (23.3%) had unilateral mydriasis, and 284 (18.3%) had bilateral mydriasis. The GCS-P score was significantly better at predicting mortality, with an AUC of 0.77 (95% CI, 0.74-0.79), versus 0.69 (95% CI, 0.67-0.72) for the GCS, and 0.75 (95% CI, 0.72-0.77) for the PRS. As the GCS-P score decreased, mortality increased. CONCLUSION: The GCS-P was more useful than the GCS for predicting death after severe head injury.
OBJETIVO: Analizar la capacidad para predecir la mortalidad hospitalaria de la Escala de Coma de Glasgow con valoración pupilar (GCS-P) comparado con la Escala de Coma de Glasgow (GCS) y con la escala de reactividad pupilar (PRS) en pacientes con traumatismo craneoencefálico (TCE) grave. METODO: Análisis retrospectivo de cohortes de todos los pacientes con TCE, puntuación en la GCS # 8 en la atención inicial, datos de exploración pupilar inicial y del desenlace hospitalario ingresados en las unidades de cuidados intensivos participantes. Se determinó la capacidad predictiva de mortalidad de la GCS, PRS y la GCS-P mediante un análisis de discriminación. La discriminación se analizó empleando curvas operativas del receptor (COR), el área bajo la curva (ABC) y su intervalo de confianza del 95% (IC 95%). RESULTADOS: Se analizaron 1.551 pacientes con TCE grave y datos sobre exploración pupilar. La edad media fue de 50 años, 1.190 (76,7%) eran hombres, y hubo 592 (38,2%) defunciones. Hubo 905 (58,3%) pacientes sin alteraciones pupilares, 362 (23,3%) con midriasis unilateral y 284 (18,3%) pacientes con midriasis bilateral. El análisis del ABCCOR para predecir la mortalidad hospitalaria mostró de forma significativa una mejor capacidad predictiva del GCS-P con ABC = 0,77 (IC 95% 0,74-0,79) respecto al GCS con ABC = 0,69 (IC 95% 0,67-0,72). La reactividad pupilar mostró un ABC = 0,75 (IC 95% 0,72-0,77). Se observó un incremento de mortalidad con la disminución del GCS-P. CONCLUSIONES: La escala GCS-P presentó mejor rendimiento que la GCS para predecir mortalidad en el TCE grave.

TEXT: The Surviving Sepsis Campaign (SSC) published a 2021 update of its 2016 recommendations. The update was awaited with great anticipation the world over, especially by emergency physicians. Under the framework of the CIMU 2022 (33rd World Emergency Medicine Conference) in Guadalajara, Mexico in March, emergency physiciansreviewed and analyzed the 2021 SSC guidelines from our specialty's point of view. In this article, the expert reviewers present their consensus on certain key points of most interest in emergency settings at this time. The main aims of the review are to present constructive comments on 10 key points and/or recommendations in the SSC 2021 update and to offer emergency physicians' experience- and evidence-based proposals. Secondarily, the review's recommendations are a starting point for guidelines to detect severe sepsis in emergency department patients and prevent progression, which is ultimate goal of what has become known as the Guadalajara Declaration on sepsis.
TEXTO: En noviembre del año 2021, la Surviving Sepsis Campaign (SSC) publicó una actualización de sus recomendaciones y directrices de 2016. Estas fueron recibidas con una enorme expectativa en todo el mundo, especialmente entre los médicos de urgencias y emergencias (MUE). Recientemente, en el marco del CIMU 2022 (33 Congreso Mundial de Medicina de Urgencias celebrado en marzo de 2022 en Guadalajara México) se ha revisado y analizado, desde la perspectiva del MUE, la Guía SSC de 2021. Los expertos que realizaron esa tarea y también consensuaron algunos de los puntos clave que más interesan y preocupan a los MUE en la actualidad han elaborado este documento. Su objetivo principal es analizar de forma constructiva diez de los puntos clave y recomendaciones de la SSC 2021 para complementarlas con argumentos y propuestas desde la experiencia, evidencia y perspectiva del urgenciólogo. Además, de forma secundaria, pretende ser el punto de partida de la elaboración de las guías para detectar, prevenir la progresión y atender a los pacientes con infección grave y sepsis en urgencias, que supone la meta final de lo que desde la MUE ya se conoce como "la Declaración de Guadalajara".
