Resumen El objetivo de este artículo fue generar un modelo reconocimiento automático de voz (RAV) basado en la traducción de la voz humana a texto, a este proceso se lo ha considerado como una de las ramas de la inteligencia artificial. El análisis de voz permite identificar información sobre la acústica, fonética, sintáctica, semántica de las palabras, entre otros elementos que pueden identificar ambigüedad en términos, errores de pronunciación, sintáctica similar pero semántica diferente, que representan características propias del lenguaje humano. El modelo se centró en el análisis acústico de las palabras, proponiendo la generación de una metodología para reconocimiento acústico, a partir de transcripciones del habla de audios que contienen voz humana. Se utilizó la tasa de error por palabra para identificar la precisión del modelo. Los audios son llamadas de emergencia registrados por el Servicio Integrado de Seguridad ECU 911. El modelo fue entrenado con la herramienta CMUSphinx para idioma español sin conexión a internet. Los resultados mostraron que la tasa de error por palabra varía en relación con la cantidad de audios; es decir a mayor cantidad de audios menor cantidad de palabras erróneas y mayor exactitud del modelo. La investigación concluyó haciendo énfasis en la duración de cada audio como variable que afecta la precisión del modelo.

Abstract The objective of the article was to generate an Automatic Speech Recognition (ASR) model based on the translation from human voice to text, being considered as one of the branches of artificial intelligence. Voice analysis allows identifying information about the acoustics, phonetics, syntax, semantics of words, among other elements where ambiguity in terms, pronunciation errors, similar syntax but different semantics can be identified, which represent characteristics of the language. The model focused on the acoustic analysis of words proposing the generation of a methodology for acoustic recognition from speech transcripts from audios containing human voice and the error rate per word was considered to identify the accuracy of the model. The audios were taken from the Integrated Security Service ECU 911 that represent emergency calls registered by the entity. The model was trained with the CMUSphinx tool for the Spanish language without internet connection. The results showed that the word error rate varies in relation to the number of audios; that is, the greater the number of audios, the smaller number of erroneous words and the greater the accuracy of the model. The investigation concluded by emphasizing the duration of each audio as a variable that affects the accuracy of the model.

Resumen Llevamos a cabo un estudio retrospectivo con el objetivo de describir las características clínicas, incidencia y desenlaces de los pacientes con injuria renal aguda (IRA) asociada a la COVID-19. Se incluyeron 162 pacientes con diagnóstico de COVID-19 admitidos en una unidad de cuidados intensivos en un hospital de tercer nivel en la Ciudad de Buenos Aires. Nuestra hipótesis consistió en que la IRA asociada a COVID-19 sería un evento temprano asociado a la gravedad de la hipoxemia y la IRA tardía se relacionaría con complicaciones propias de la UCI. Por ello se clasificó la IRA en temprana y tardía, según sucediera antes o después de los 14 días desde el inicio de síntomas. Se realizó un análisis multivariado mediante regresión logística escalonada para evaluar posibles factores de riesgo. La incidencia de IRA fue de 43.2% (n = 70), 11.1% (n = 18) requirieron terapia de reemplazo renal. La mortalidad intrahospitalaria fue mayor (58.6%) en el grupo con IRA. El diagnóstico de IRA se realizó en una mediana de 10 (IQR = 5.5-17.5) días desde el inicio de los síntomas. El antecedente de hipertensión e insuficiencia cardíaca, la edad y el requerimiento de ventilación mecánica invasiva (VMI) fueron identificados como factores de riesgo para IRA. La IRA tardía (n = 25, 35.7%) estuvo asociada a sepsis y expo sición a nefrotóxicos, mientras que la IRA temprana (n = 45, 64.2%) estuvo temporalmente asociada al inicio de la VMI y en muchos casos no se pudo filiar una etiología. En conclusión, la IRA es una complicación frecuente en pacientes con COVID-19 grave y está asociada a una alta mortalidad intrahospitalaria.

Abstract We conducted a retrospective cohort study to report the clinical characteristics, incidence and out-comes of patients with severe COVID-19 with acute kidney injury (AKI). One-hundred and sixtytwo intensive care unit (ICU) admitted patients in a tertiary level hospital in the city of Buenos Aires with COVID-19 diagnosis were included. We hypothesized that COVID-19 related AKI would develop in the period of more severe hypoxemia as an early event and late AKI would be more probably related to intensive care unit complications. For this purpose, we divided subjects into two groups: those with early AKI and late AKI, before and after day 14 from symptom onset, respectively. A stepwise multivariate analysis was conducted to find possible AKI predictors. AKI incidence was 43.2% (n = 70) of the total patients admitted into ICU with severe COVID-19, 11.1% (n = 18) required renal replacement therapy. In-hospital mortality was higher (58.6%) for the AKI group. AKI occurred on a median time of 10 (IQR 5.5-17.5) days from symptom onset. A history of hypertension or heart failure, age and invasive mechanical ventilation (IMV) requirement were identified as risk factors. Late AKI (n = 25, 35.7%) was associated with sepsis and nephrotoxic exposure, whereas early AKI occurred closer to the timing of IMV initiation and was more likely to have an unknown origin. In conclusion, AKI is frequent among critically ill patients with severe COVID-19 and it is associated with higher in-hospital mortality.

ABSTRACT BACKGROUND: The intensity of the thromboprophylaxis needed as a potential factor for preventing inpatient mortality due to coronavirus disease-19 (COVID-19) remains unclear. OBJECTIVE: To explore the association between anticoagulation intensity and COVID-19 survival. DESIGN AND SETTING: Retrospective observational study in a tertiary-level hospital in Spain. METHODS: Low-molecular-weight heparin (LMWH) status was ascertained based on prescription at admission. To control for immortal time bias, anticoagulant use was analyzed as a time-dependent variable. RESULTS: 690 patients were included (median age, 72 years). LMWH was administered to 615 patients, starting from hospital admission (89.1%). 410 (66.7%) received prophylactic-dose LMWH; 120 (19.5%), therapeutic-dose LMWH; and another 85 (13.8%) who presented respiratory failure, high D-dimer levels (> 3 mg/l) and non-worsening of inflammation markers received prophylaxis of intermediate-dose LMWH. The overall inpatient-mortality rate was 38.5%. The anticoagulant nonuser group presented higher mortality risk than each of the following groups: any LMWH users (HR 2.1; 95% CI: 1.40-3.15); the prophylactic-dose heparin group (HR 2.39; 95% CI, 1.57-3.64); and the users of heparin dose according to biomarkers (HR 6.52; 95% CI, 2.95-14.41). 3.4% of the patients experienced major hemorrhage. 2.8% of the patients developed an episode of thromboembolism. CONCLUSIONS: This observational study showed that LMWH administered at the time of admission was associated with lower mortality among unselected adult COVID-19 inpatients. The magnitude of the benefit may have been greatest for the intermediate-dose subgroup. Randomized controlled trials to assess the benefit of heparin within different therapeutic regimes for COVID-19 patients are required.

Resumo: Atualmente o hotspot da Mata Atlântica tem menos de 11% de sua cobertura original. Porém aproximadamente 300 espécies de répteis são conhecidas por habitar esta ecorregião, das quais 34% são endêmicas. A criação de unidades de conservação representa uma estratégia de preservação de ecossistemas e gestão do uso do solo, e para o manejo adequado dessas áreas protegidas é fundamental a informação sobre a biodiversidade local. Apresentamos aqui a primeira lista de espécies de répteis para a Estação Ecológica e Área de Proteção Ambiental de Murici, duas unidades de conservação parcialmente sobrepostas localizadas no estado de Alagoas, um dos conjuntos de remanescentes florestais mais importantes para a conservação da Mata Atlântica no nordeste do Brasil. A lista de espécies foi construída com base em expedições e encontros ocasionais na área entre 1994 e 2022. Um total de 89 espécies de répteis foram registradas durante os 28 anos de coleta, sendo duas espécies de Crocodylia, três espécies de Testudines e 84 espécies de Squamata. Essa riqueza é de longe uma das maiores já documentadas para a Mata Atlântica. Além disso, duas espécies registradas na área são consideradas ameaçadas segundo a lista nacional (Amerotyphlops paucisquamus e Bothrops muriciensis) e seis são definidas como dados insuficientes para a avaliação de seu status de conservação. Três espécies são registradas pela primeira vez na Mata Atlântica ao norte do rio São Francisco: Dipsas indica, Trilepida salgueiroi e Cercophis auratus. Afirmamos que a lista de espécies aqui fornecida servirá como ponto de partida para novos estudos neste rico “hotspot” de répteis dentro da Mata Atlântica.

Abstract: Currently the Atlantic Forest hotspot has less than 11% of its original coverage. However approximately 300 species of reptiles are known to inhabit this ecoregion, of which 34% are endemic. The creation of protected areas represents a strategy for preserving ecosystems and managing land use, and for attaining the proper management of these protected areas, information on local biodiversity is essential. Herein we provide the first list of reptile species for the Estação Ecológica and Área de Proteção Ambiental de Murici, two overlapping protected areas located in the state of Alagoas, one of the most important sets of forest remnants for the conservation of the Atlantic Forest in the northeast of Brazil. The species list was constructed based on expeditions and occasional encounters in the area between 1994 and 2022. A total of 89 reptile species were obtained during the 28 years of collection, being two species of Crocodylia, three species of Testudines and 84 species of Squamata. This richness is by far one of the greatest ever documented for the Atlantic Forest. Additionally, two species registered in the area are considered threatened according to the national list (Amerotyphlops paucisquamus and Bothrops muriciensis) and six are defined as data deficient for the assessment of their conservation status. Three species are recorded for the first time in the Atlantic Forest north of the São Francisco River: Dipsas indica, Trilepida salgueiroi and Cercophis auratus. We claim that the species list provided here will serve as a starting point for further studies in this rich reptile “hotspot” within the Atlantic Forest.

Abstract The development of low-cost high quality surface finishing methods for silicon carbide (SiC) is an arduous task. Nowadays, the SiC mirrors manufacture involves extensive, complex, and costly finishing processes carried out on highly expensive ultra-precise machines. In this work, a cost-effective surface finishing method has been successfully developed, using conventional machines for the optical finishing of SiC. The results showed that the combination of ductile grinding and polishing in conventional low-cost machines allowed to obtain high-quality surface finish on SiC substrates with low roughness (4 - 10 nm Ra ) and optical figure in the range λ / 4 - λ / 8, at a reduced 32 hours total processing time.

Abstract The classification of Synthetic Aperture Radar (SAR) images by knowledge-based algorithms with elevation and backscatter thresholds were used in several studies to detect the Wet Snow Radar Zone (WSZ) in the Antarctic Peninsula. To identify it more accurately based on its seasonal variations, this study proposed the additional use of a threshold in synthetic images, created by rationing summer and winter sigma linear images. In our algorithm we used the following thresholds to detect the WSZ in Envisat ASAR imageries, using the Radarsat Antarctic Map Digital Elevation Model as ancillary data: i) -25 dB < s0 < -14 dB; ii) slinear summer / slinear winter < 0.4; iii) elevation H < 1,200 m for northern tip and H < 800 m for southern tip of the Antarctic Peninsula. The classified images were post-processed by a focal majority 5 x 5 filter and superimposed by an image of rock outcrops derived from the Antarctic Digital Database. The ratio image threshold allowed discriminating the WSZ from the Dry Snow Radar Zone and radar shadows, as well as transitional areas between this glacier zone and the Frozen Percolation Radar Zone, which would be classified incorrectly if we used only elevation and backscatter thresholds.

ABSTRACT Objective: To evaluate the involvement of orthopedists and orthopedic residents with fragility fractures, in its clinical, therapeutic, and social aspects. Methods: Cross-sectional observational and prospective study that took place in the period from June to August 2020. Results: 540 participants were analyzed. The population consisted of orthopedists (85.56%; N = 462) and residents (14.44%; N = 78), with a greater proportion of individuals from 41 to 50 years of age (36.67%; N = 198) and from the Southeast region (57.22%; N = 309). For 47.04% (N = 254) of the participants, the profile of the patient at risk for fragility fracture corresponds to: woman, sedentary, smoker and over 60 years of age. The consensus among the participants (97.96%; N = 529) is that fragility fractures occur in or near home environments. Moreover, 47.59% (N = 257) believe that the first fragility fracture is the most important predictive risk factor for subsequent occurrences and 63.89% (N = 345) of the participants claim to attend more than 15 cases per year. Regarding treatment, 74.44% (N = 402) are dedicated exclusively to orthopedic aspects (68.33%; N = 369). However, 62.41% (N = 337) of the participants believe that patients with fragility fractures should receive medication and supplements. Likewise, 70.74% (N = 382) of the participants consider that home security measures and training of family members are important, and they attribute the role to the multidisciplinary team. Conclusions: Fragility fractures are frequent in the routine of Brazilian orthopedists. However, they are not familiar with adjuvant treatments for fragility fractures, acting almost exclusively in the orthopedics aspects of these injuries. Level of Evidence II, Prospective Study.

RESUMO Objetivo: Avaliar o entendimento entre ortopedistas e residentes em ortopedia sobre as fraturas por fragilidade, em seus aspectos clínicos, terapêuticos e sociais. Métodos: Estudo transversal, observacional e prospectivo que ocorreu no período de junho de agosto de 2020. Resultados: Foram analisados 540 participantes. A população foi composta por ortopedistas (85,56%; N = 462) e residentes (14,44%; N = 78), com prevalência de idade entre 41 e 50 anos (36,67%; N=198) e oriundos da região Sudeste (57,22%; N = 309). Para 47,04% (N = 254) dos participantes o perfil do paciente em risco para fratura por fragilidade corresponde a: mulher, sedentária, tabagista e acima dos 60 anos de idade. Sendo consenso entre os participantes (97,96%; N = 529) que as fraturas por fragilidade ocorrem em ambientes domiciliares ou próximo a eles. Além disso, 47,59% (N = 257) dos participantes acreditam que a primeira fratura por fragilidade seja o fator de risco preditivo mais importante para novo episódio de fratura e 63,89% (N = 345) dos avaliadores atendem mais de 15 casos por ano. Em relação ao tratamento, 74,44% (N = 402) dedicam-se exclusivamente aos aspectos ortopédicos (68,33%; N = 369). No entanto, 62,41% (N = 337) dos participantes acreditam que paciente devam receber medicamentos e suplementos. Da mesma forma, 70,74% (N = 382) dos avaliadores consideram que medidas de segurança domiciliar e treinamento de familiares sejam importantes e atribuídas a equipe multiprofissional. Conclusão: As fraturas por fragilidade são frequentes na rotina dos ortopedistas brasileiros. No entanto, estes não estão familiarizados com tratamentos adjuvantes nas fraturas consideradas por fragilidade, atuando quase que exclusivamente nos aspectos ortopédicos envolvidos nestas lesões. Nível de Evidência II, Estudo Prospectivo.

The aim of this study was to investigate interprofessional communication and reporting adverse events as a patient care and safety strategy in an intensive care unit. We conducted a qualitative descriptive with 31 health professionals working in an adult intensive care unit using individual interviews. The data was analyzed using content analysis, resulting in two core thematic categories: a) Interprofessional collaboration and communication potential; b) Barriers, impediments and weaknesses, encompassing views of interprofessional collaboration, strategies for putting collaboration into practice, reporting weaknesses, fear, and lack of knowledge. The professionals demonstrated that communication is important for interprofessional reporting of adverse events; however, they need to unite with each other and managers to build a culture of safety and mitigate fears and lack of knowledge of procedures and facilitators.

El objetivo fue conocer la comunicación interprofesional y la notificación de Eventos Adversos como estrategia de promoción del cuidado y seguridad del paciente en la Unidad de Cuidados Intensivos. Como método se utilizó un estudio descriptivo-cualitativo realizado con 31 profesionales de la Unidad de Cuidados Intensivos Adulto por medio de una entrevista de carácter individual con posterior análisis de contenido. Surgieron dos macrocategorías temáticas: a) Trabajo interprofesional y potencialidades para concretar la comunicación y b) Obstáculos, impedimentos y fragilidades, abordando conjuntamente la perspectiva del trabajo interprofesional, estrategias para efectivarlo, fragilidades en las notificaciones, miedos y desconocimiento. Se considera que los profesionales demuestran que la comunicación es importante para la notificación de eventos adversos interprofesionalmente, pero necesitan unificarse entre sí y con los gestores con la finalidad de construir una cultura de seguridad y mitigar miedos y desconocimiento sobre el procedimiento y sus facilitadores.

Objetivou-se conhecer a comunicação interprofissional e a notificação de eventos adversos como estratégia de promoção do cuidado e da Segurança do Paciente na Unidade de Terapia Intensiva. Tomou-se como método um estudo descritivo-qualitativo realizado com 31 profissionais da Unidade de Terapia Intensiva adulto, por meio de entrevista de caráter individual com posterior análise de conteúdo. Emergiram duas macrocategorias temáticas: a) Trabalho interprofissional e potencialidades para concretizar a comunicação e b) Entraves, impedimentos e fragilidades, abordando conjuntamente a perspectiva do trabalho interprofissional, estratégias para efetivá-lo, fragilidades nas notificações, medos e desconhecimento. Considera-se que os profissionais demonstram que a comunicação é importante para a notificação de eventos adversos interprofissionalmente, porém necessitam se unificar, entre eles e com gestores, a fim de construir uma cultura de segurança e mitigar medos e desconhecimento sobre o procedimento e seus facilitadores.

Abstract Pandemics pose a major challenge for public health preparedness, requiring a coordinated international response and the development of solid containment plans. Early and accurate identifica tion of high-risk patients in the course of the current COVID-19 pandemic is vital for planning and making proper use of available resources. The purpose of this study was to identify the key variables that account for worse outcomes to create a predictive model that could be used effectively for triage. Through literature review, 44 variables that could be linked to an unfavorable course of COVID-19 disease were obtained, including clinical, laboratory, and X-ray variables. These were used for a 2-round modified Delphi processing with 14 experts to select a final list of variables with the greatest predictive power for the construction of a scoring system, leading to the creation of a new scoring system: the COVID-19 Severity Index. The analysis of the area under the curve for the COVID-19 Severity Index was 0.94 to predict the need for ICU admission in the following 24 hours against 0.80 for NEWS-2. Additionally, the digital medical record of the Hospital Italiano de Buenos Aires was electronically set for an automatic calculation and constant update of the COVID-19 Severity Index. Specifically designed for the current COVID-19 pandemic, COVID-19 Severity Index could be used as a reliable tool for strategic planning, organization, and administration of resources by easily identifying hospitalized patients with a greater need of intensive care.

Resumen La pandemia por COVID-19 planteó un desafío para el sistema salud, debido a la gran demanda de pacientes hospitalizados. La identificación temprana de pacientes hospitalizados con riesgo de evo lución desfavorable es vital para asistir en forma oportuna y planificar la demanda de recursos. El propósito de este estudio fue identificar las variables predictivas de mala evolución en pacientes hospitalizados por COVID-19 y crear un modelo predictivo que pueda usarse como herramienta de triage. A través de una revisión narrativa, se obtuvieron 44 variables vinculadas a una evolución desfavorable de la enfermedad COVID-19, incluyendo variables clínicas, de laboratorio y radiográficas. Luego se utilizó un procesamiento por método Delphi modificado de 2 rondas para seleccionar una lista final de variables incluidas en el score llamado COVID-19 Severity Index. Luego se calculó el Área Bajo la Curva (AUC) del score para predecir el pase a terapia intensiva en las próximas 24 horas. El score presentó un AUC de 0,94 frente a 0,80 para NEWS-2. Finalmente se agregó el COVID-19 Severity Index a la historia clínica electrónica de un hospital universitario de alta complejidad. Se programó para que el mismo se actualice de manera automática, facilitando la planificación estratégica, organización y administración de recursos a través de la identificación temprana de pacientes hospitalizados con mayor riesgo de transferencia a la Unidad de Cuidados Intensivos.
