Abstract The authors report the case of a 71-year-old woman presented to the Emergency Department with acute ischemic stroke. She was treated with rt-PA and interventional endovascular revascularization and developed rapidly progressing angioedema that led to emergency intubation. The standard treatment was not very effective and the swelling improved after infusion of fresh frozen plasma. Angioedema after rt-PA infusion could be a life-threatening emergency that requires quick airway management by skilled professionals. As this condition is triggered by several factors, such as unregulated histamine and bradykinin production, the traditional treatment recommended by the guidelines may not be sufficient and the use of FFP can be considered as a safe and valuable aid.

RESUMEN El aumento de las fuentes de fertilización será necesario para satisfacer la creciente demanda de alimentos en todo el mundo. Por este motivo, las enmiendas orgánicas surgen como una alternativa a los fertilizantes sintéticos. El compostaje de residuos orgánicos estabiliza el contenido de nitrógeno (N) y retrasa la liberación de N al suelo. La aplicación de enmiendas compostadas al suelo podría reducir las pérdidas de N, incluido el óxido nitroso (N2O), un gas de efecto invernadero con gran potencial de calentamiento global. El objetivo de este trabajo fue evaluar la emisión de N2O desde un suelo Argiudol típico luego de aplicar un fertilizante sintético tradicional, guano de ave crudo y compostado y un suelo control. Las tasas emisión de N2O acumuladas durante los 32 días que duro el ensayo fueron 1273, 965, 423 y 244 g de N2O-N ha-1 desde el suelo con aplicación de urea, guano de ave, compost de guano de ave y control, respectivamente. Nuestros resultados sugieren que la aplicación de compost de guano al suelo produce menores emisiones de N2O que la aplicación de guano de ave crudo o de urea. La presencia de compuestos más estabilizados en el compost de guano disminuye la disponibilidad de nitrato del suelo.

ABSTRACT Diversification in fertilizer sources will be necessary to meet the growing demand for food worldwide. For this reason, organic amendments emerge as a synthetic fertilizers alternative. Composting organic waste stabilizes the nitrogen (N) content and delays N release to the soil. Applying composted amendments to the soil could reduce the losses of N, including nitrous oxide (N2O), a greenhouse gas with great potential for global warming. The objective of this work was to evaluate the N2O emission in typical Argiudol soil after applying a traditional synthetic fertilizer, raw poultry manure, composted poultry manure and control soil. Cumulative N2O emission rates during the 32 days of the trial were 1273, 965, 423, and 244 g N2O-N/ha-1 from the soil using urea, poultry manure, composted poultry manure, and control, respectively. Our results suggest that the application of composted poultry manure to the soil produces lower N2O emissions than the application of raw poultry manure or urea. The presence of more stabilized compounds in the composted manure decreases the soil nitrate availability.

ABSTRACT Background We investigated the mortality rates of patients with Chagas disease (CD) during the coronavirus disease 2019 (COVID-19) pandemic and assessed the association between this mortality and CD clinical presentation and comorbidities. Methods: This was an observational retrospective study with clinical data retrieved from medical records. Results: Comorbidities were more prevalent among patients who died from COVID-19 than those who died from other causes. The proportion of patients according to CD clinical presentation was similar between the two groups. Conclusions: The prevalence of comorbidities seems to be related to a poorer prognosis in CD and COVID-19.

ABSTRACT Objective Phase 1 clinical trial to determine feasibility, safety, and efficacy of a new advanced cell therapy product for treatment of knee articular cartilage injuries. Methods Three participants with knee focal chondral lesions were included, with no signs of osteoarthritis. Chondrocytes were obtained through knee arthroscopy, cultured in collagen membrane for 3 weeks at the laboratory, subjected to tests to release the cell therapy product, and implanted. All patients underwent a specific 3-month rehabilitation protocol, followed by assessments using functional and imaging scales. The main outcome was the incidence of severe adverse events. Results Three participants were included and completed the 2-year follow-up. There was one severe adverse event, venous thrombosis of distal leg veins, which was no associated with therapy, was treated and left no sequelae. The clinical and radiological scales showed improvement in the three cases. Conclusion The preliminary results, obtained with the described methodology, allow concluding that this product of advanced cell therapy is safe and feasible.

ABSTRACT To describe a case of autologous chondrocyte implantation after cell culture contamination by Mycoplasma pneumoniae and the measures taken to successfully complete cell therapy in a patient with focal chondral lesion. A 45-year-old male patient, complaining of chronic pain on the knee and no history of trauma. He had a chondral lesion in the trochlear region of the femur and clinical tests compatible with pain in the anterior compartment of the knee. Conservative treatment failed to alleviate symptoms. Surgical treatment was indicated, but due to the size of the lesion, membrane-assisted autologous chondrocyte implantation was the technique of choice. Cartilage biopsies were collected from the intercondylar region of the distal femur. After isolation, chondrocytes were expanded ex vivo in a trained laboratory, for three weeks, and seeded onto a commercially available collagen membrane prior to implantation in the knee. Two days before surgery, a cell culture sample tested positive for Mycoplasma pneumoniae. The source of contamination was found to be autologous blood serum, extracted from the patient´s peripheral vein, and used to supplement the cell culture medium. After treating the patient with antibiotics, all procedures were repeated and the new final cell product, free from contaminants, was successfully implanted. We discuss the strategies available to deal with this situation, and describe the results of this particular case, which led to modifications in the autologous chondrocyte implant protocol.

ABSTRACT Hypopituitarism is a disorder characterized by insufficient secretion of one or more pituitary hormones. New etiologies of hypopituitarism have been recently described, including head trauma, cerebral hemorrhage, and drug-induced hypophysitis. The investigation of patients with these new disorders, in addition to advances in diagnosis and treatment of hypopituitarism, has increased the prevalence of this condition. Pituitary hormone deficiencies can induce significant clinical changes with consequent increased morbidity and mortality rates, while hormone replacement based on current guidelines protects these patients. In this review, we will first discuss the different etiologies of hypopituitarism and then address one by one the clinical aspects, diagnostic evaluation, and therapeutic options for deficiencies of TSH, ACTH, gonadotropin, and GH. Finally, we will detail the hormonal interactions that occur during replacement of pituitary hormones.

OBJECTIVES: To compare the effects of low-dose conjugated estrogen (CE), raloxifene, and the combination thereof on the endometrium of postmenopausal women. METHODS: Postmenopausal women between 45 and 60 years of age, with Gail score≥1.67 and no endometrial disorders, were randomly assigned to receive low-dose CE (0.3 mg), raloxifene (60 mg), or combined therapy for 1 year. Transvaginal ultrasound was performed at baseline and every 3 months; the Kupperman Index was assessed at baseline and every 6 months. Endometrial biopsies were performed if endometrial thickness (ET) was ≥5 mm or if vaginal bleeding occurred. The primary outcome was the occurrence of ET≥5 mm over the one-year period. RESULTS: Seventy-three women were randomly assigned and analyzed on an intent-to-treat basis. Eight, three, and four women in the CE, raloxifene, and combination groups, respectively, exhibited ET≥5 mm. No genital bleeding was reported in the combination group. Endometrial biopsy revealed atrophy or polyps in all groups, with one patient in the CE group exhibiting a proliferative endometrium without atypia. At 6 months, there was a progressive increase in mean ET in the CE group, but not in the other two groups, with statistically significant differences at 6, 9, and 12 months. Mean scores for vasomotor symptoms and Kupperman Index favored the CE and combination groups over raloxifene. CONCLUSION: Combined raloxifene and low-dose CE decreased the severity of menopausal symptoms to a similar extent as CE alone and had similar effects as raloxifene alone on the endometrium.

Abstract This paper presents major gaps and challenges for implementing the UN Decade of Ocean Science for Sustainable Development (2021-2030) in the Mediterranean region. The authors make recommendations on the scientific knowledge needs and co-design actions identified during two consultations, part of the Decade preparatory-phase, framing them in the Mediterranean Sea’s unique environmental and socio-economic perspectives. According to the ‘Mediterranean State of the Environment and Development Report 2020’ by the United Nations Environment Programme Mediterranean Action Plan and despite notable progress, the Mediterranean region is not on track to achieve and fully implement the Sustainable Development Goals of Agenda 2030. Key factors are the cumulative effect of multiple human-induced pressures that threaten the ecosystem resources and services in the global change scenario. The basin, identified as a climate change vulnerability hotspot, is exposed to pollution and rising impacts of climate change. This affects mainly the coastal zones, at increasing risk of extreme events and their negative effects of unsustainable management of key economic assets. Transitioning to a sustainable blue economy is the key for the marine environment’s health and the nourishment of future generations. This challenging context, offering the opportunity of enhancing the knowledge to define science-based measures as well as narrowing the gaps between the Northen and Southern shores, calls for a joint (re)action. The paper reviews the state of the art of Mediterranean Sea science knowledge, sets of trends, capacity development needs, specific challenges, and recommendations for each Decade’s societal outcome. In the conclusions, the proposal for a Mediterranean regional programme in the framework of the Ocean Decade is addressed. The core objective relies on integrating and improving the existing ocean-knowledge, Ocean Literacy, and ocean observing capacities building on international cooperation to reach the “Mediterranean Sea that we want”.

Resumo Este artigo abre um debate sobre as condições de circulação e recepção transnacional das obras como fator de diferenciação nas carreiras literarias nacionais. O objetivo central é mostrar de que modo as dinâmicas da tradução funcionam como recursos possíveis para reconhecimento e consagração, considerando escritores posicionados nas margens da produção simbólica nacional. O percurso do escritor José Mauro de Vasconcelos, cuja obra descreve movimentos entre a literatura e o audiovisual a partir de 1950, estabelece relações explicativas de alto rendimento analítico com a problemática da recepção transnacional da produção brasileira. A confluência e a transferência entre cânones nacionais, além de aproximar escalas de observação dos regimes de autoria, vinculam-se à circulação da literatura popular sentimental para além dela mesma.

Abstract This article opens a debate about the transnational circulation and reception conditions of the works as a differential factor in the national literary careers. The main objective is to show in which way the dynamics of translation work as possible resources for recognition and consecration, considering writers positioned on the borders of national symbolic production. The path of the writer José Mauro de Vasconcelos, whose work describes movements between literature and audiovisual from 1950, establishes explanatory relations of high analytical performance with the problematics of the Brazilian production transnational reception. The confluence and the transfer between national canons, aside from approximating the observation scales of the authorship regime, is linked to the sentimental popular literary circulation beyond itself.

SUMMARY: The exercise could play a central role to the fat management and glucose metabolism what can be a critical role in the health status of diabetic people, but the high intense exercise remains with controversial data about their effects. To identify the effect of the multimodal high-intensity interval training on body composition, lipid profile, and glucose metabolism in elderly diabetics. Methods: Elderly diabetic individuals (n = 48) were randomly divided in a Sedentary Control (SC) group, a Moderate-Intensity Continuous Training (MICT) group, and a High-Intensity Interval Training (HIIT) group. MICT and HITT were conducted over 60 days, 3x per week, with 40 minutes of exercise. Blood was collected prior to intervention, at four, and at eight weeks subsequently to assess glucose metabolism and lipid profiles. Body composition was determined before and after the intervention period. To verify the normality Kolmogorov-Smirnov statistical test was performed, followed by student "t" test or two-way ANOVA with Bonferroni’s post hoc test with significance of 5 % the Cohen’s f test to indicate the magnitude of the differences. HIIT significantly lowered cholesterol and triglyceride levels, and significantly lowered blood glucose and glycosylated haemoglobin levels (p<0.05). MICT and HIIT significantly increased levels of high-density lipoprotein, decreased total body mass and body mass index. HIIT resulted in significantly smaller waist circumferences, waist-to-hip ratios, and weight-to-height ratios over 60 days of training. HIIT is more effective than MICT for improving lipid and glycaemic profiles, decreasing body fat, and improving fat distribution elderly diabetics.

RESUMEN: El ejercicio podría desempeñar un papel central en el manejo de la grasa y el metabolismo de la glucosa, lo que puede ser un papel crítico en el estado de salud de las personas diabéticas, pero el ejercicio intenso intenso sigue teniendo datos controvertidos sobre sus efectos. El objetivo del estudio fue identificar el efecto del entrenamiento multimodal de intervalos de alta intensidad sobre la composición corporal, el perfil lipídico y el metabolismo de la glucosa en diabéticos de edad avanzada. Los individuos diabéticos de edad avanzada (n = 48) se dividieron aleatoriamente en un grupo de control sedentario (SC), un grupo de entrenamiento continuo de intensidad moderada (MICT) y un grupo de entrenamiento de intervalos de alta intensidad (HIIT). MICT y HITT se realizaron durante 60 días, 3 veces por semana, con 40 minutos de ejercicio. Se recogió sangre antes de la intervención, a las cuatro y a las ocho semanas posteriormente para evaluar el metabolismo de la glucosa y los perfiles de lípidos. La composición corporal se determinó antes y después del período de intervención. Para verificar la normalidad se realizó la prueba estadística de Kolmogorov-Smirnov, seguida de la prueba "t" de Student o ANOVA de dos vías con la prueba post hoc de Bonferroni con una significancia del 5 % de la prueba f de Cohen, indicando las diferencias. HIIT redujo significativamente los niveles de colesterol y triglicéridos, además de reducir de manera importante los niveles de glucosa en la sangre y la hemoglobina glicosilada (p <0.05). MICT y HIIT aumentaron significativamente los niveles de lipoproteína de alta densidad, disminuyeron la masa corporal total y el índice de masa corporal. HIIT resultó en circunferencias de cintura significativamente más pequeñas, relaciones cintura-cadera y relaciones peso-altura durante 60 días de entrenamiento. HIIT es más efectivo que MICT para mejorar los perfiles de lípidos y glucémicos, disminuir la grasa corporal y mejorar la distribución de grasa en los diabéticos de edad avanzada.

Resumen Este artículo presenta una caracterización de la transmisión inalámbrica de señales biomecánicas en un sistema embebido, donde se utiliza un protocolo TCP en una red de comunicaciones IEEE 802.11 (Wi-Fi). El sistema embebido en estudio, denominado Imocap, permite la recogida, análisis y transmisión de señales biomecánicas en tiempo real para diversas aplicaciones, entre las que destacan el análisis del movimiento de las extremidades inferiores y superiores y la activación de diversos sistemas de control. Para este fin, Imocap está equipado con un módulo transceptor Wi-Fi (ESP8266) y varios periféricos de entrada y salida. El desempeño de la comunicación inalámbrica de Imocap, expuesto en este trabajo, fue analizado a través de diferentes pruebas en condiciones diversas como en interiores, exteriores y en presencia de interferencia, ruido y otras redes inalámbricas. Los diferentes protocolos de prueba realizados dan como resultado que el sistema Imocap: 1) tiene un alcance efectivo máximo de 45,6 m cuando está en modo Access Point; 2) tiene un alcance efectivo máximo de 44,3 m cuando está en modo Station. En interior y en las mismas condiciones, el sistema Imocap: 3) tiene un alcance efectivo máximo de 81,25 m2, ya sea en modo Punto de Acceso o en modo Estación. Los resultados mostraron que la transmisión de información biomecánica a través de Wi-Fi utilizando el protocolo TCP es eficiente y robusta, tanto en interiores como en exteriores, incluso en entornos de interferencia de radiofrecuencia. Se destaca el uso de este protocolo ya que su uso permite que la transmisión de paquetes se realice de forma controlada, permitiendo el manejo y recuperación de errores. De esta manera, es posible llevar a cabo una comunicación inalámbrica eficiente y robusta a través de dispositivos embebidos y portátiles, centrándose principalmente en áreas como la medicina, la telemedicina y la telerehabilitación.

Abstract This paper presents a characterization of the wireless transmission of biomechanical signals in an embedded system, where a TCP protocol is used in an IEEE 802.11 communications network (Wi-Fi). The embedded system under study, called Imocap, allows the collection, analysis and transmission of biomechanical signals in real-time for various applications, among which the analysis of the movement of the lower and upper extremities and the operation of various control systems stand out. To accomplish this, Imocap is equipped with a Wi-Fi transceiver module (ESP8266) and various input and output peripherals. The wireless communication performance of Imocap, exposed in this paper, was analyzed through different tests in miscellaneous conditions like indoors, outdoors and in the presence of interference, noise and other wireless networks. The different test protocols conducted result in the Imocap system: 1) has a maximum effective range of 45.6 m when in Access Point mode; 2) has a maximum effective range of 44.3 m when in Station mode. In indoors and under the same conditions, the Imocap system: 3) has a maximum effective range of 81.25 m2, either Access Point or Station mode. The results showed that the transmission of biomechanical information through Wi-Fi using the TCP protocol is efficient and robust, both indoors and outdoors, even in environments of radio frequency interference. The use of this protocol is emphasized since its use allows the transmission of packages to be carried out in a controlled manner, allowing the error handling and recovery. In this way, it is possible to carry out efficient and robust wireless communication through embedded and portable devices, focusing mainly on areas such as medicine, telemedicine and telerehabilitation.

Desta maneira, é possível levar a cabo uma comunicação sem fio eficiente e robusta através de dispositivos embebidos e portáteis, centrando-se principalmente em áreas como a medicina, a telemedicina e a telereabilitação.

Abstract Introduction: socio-economic differences lead to food and nutritional inequalities. Diet is a modifiable risk factor by public health activities, on the way to the prevention of chronic non-communicable diseases. Objective: to estimate food inequalities in Argentina based on the socioeconomic level of the population, analyzing the consumption of different food groups. Methods: Argentine data from the Latin American Study of Nutrition and Health. Sample: 1,266 individuals stratified by gender, socioeconomic level and geographic region. Intake: 2 24-hour reminders with the multi-step technique. Analysis: with the NDS Software average consumption values of 11 food groups were analyzed by socioeconomic level and country region. Results: the population with lower socioeconomic status consumes significantly less fruits, vegetables and dairy products than the population with medium to high socioeconomic level. Fruits: 59 vs. 79.1 and 106.3 g/d, respectively; p = 0.000. Vegetables: 82.3 g/d vs. 112 and 118 g/d; p = 0.000. Dairy products: 114 g/d vs. 165 and 137 g/d; p = 0.000). On the contrary, it consumes a greater volume of soft drinks and industrial juices (680 mL/d vs. 527 and 590 mL/d, respectively; p = 0.000), infusions with added sugar (568 mL/d vs. 385 and 309 mL/d; p = 0.000), bread (85 g/d vs. 75.5 and 66.7 g/d; p = 0.012) and pastries (159 g/d vs. 147 and 122 g/d; p = 0.008). Conclusions: Social vulnerability is an important determinant for diet quality. Interventions designed to reduce social inequalities as linked to nutrition and health are essential.

Resumen Introducción: las diferencias socioeconómicas acarrean desigualdades alimentarias y nutricionales. La dieta es un factor de riesgo modificable con acciones de salud pública, camino a la prevención de enfermedades crónicas no transmisibles. Objetivo: estimar las desigualdades alimentarias en Argentina en función del nivel socioeconómico de la población, analizando el consumo de distintos grupos de alimentos. Métodos: datos argentinos del Estudio Latinoamericano de Nutrición y Salud. Muestra: 1266 individuos estratificados por género, nivel socioeconómico y región geográfica. Ingesta: 2 recordatorios de 24 horas con técnica de pasos múltiples. Análisis: con el NDS Software se analizaron los valores medios de consumo de 11 grupos de alimentos por nivel socioeconómico y región del país. Resultados: la población con menor nivel socioeconómico consume significativamente menos frutas, verduras y lácteos que la población de nivel medio y alto. Frutas: 59 vs. 79,1 y 106,3 g/d, respectivamente; p = 0,000. Verduras: 82,3 vs. 112 y 118 g/d; p = 0,000. Lácteos: 114 vs. 165 y 137 g/d; p = 0,000). Por el contrario, consume un mayor volumen de refrescos y jugos industriales (680 ml/d vs. 527 y 590 ml/d, respectivamente; p = 0,000), infusiones con azúcar agregada (568 ml/d vs. 385 y 309 ml/d; p = 0,000), pan (85 g/d vs. 75,5 y 66,7 g/d; p = 0,012) y bollería (159 g/d vs. 147 y 122 g/d; p = 0,008). Conclusiones: la vulnerabilidad social es un determinante importante de la calidad de la dieta. Intervenciones diseñadas para reducir las desigualdades sociales vinculadas a la nutrición y la salud resultan imprescindibles.

OBJECTIVES: Adolescence is characterized by continuing profound mental, physical, and social changes and entering into the labor market during this phase may have negative consequences on physical and mental health. Common mental disorders (CMD) are characterized as disorders of mental functions, including symptoms of depression and anxiety as well as various nonspecific and somatic complaints such as reduced ability to concentrate, tiredness, irritation, and forgetfulness. Despite its increasing prevalence, few studies have addressed CMD and its association with work, in adolescents. In the present study, we aimed to identify the main factors associated with CMD and evaluated its association with work, in school adolescents. METHODS: A cross-sectional study was conducted with 12 to 17-year-old adolescent students using a self-administered questionnaire with questions related to work. CMD was verified using the General Health Questionnaire of 12 items. In total, 3424 adolescents were studied. RESULTS: The prevalence of CMD and work in the last year was 28.72% and 19.63%, respectively. After adjustment for potential confounding variables, multivariate analysis showed associations of CMD with female gender (OR=2.72) and work (OR=1.70). CONCLUSION: In the present study, a high number of cases of CMD were observed among the studied adolescents. Female gender and work history in the last year were negatively and independently associated with the presence of CMD.

Resumo A evolução da educação a distância (ED) tem satisfeito diversas necessidades educativas, graças ao progresso tecnológico, iniciativas docentes na educação superior e pesquisa educativa. Porém, na ED confluem múltiplas relações entre as capacidades, formas de aprendizagem, participação na toma de decisões dos atores e agentes envolvidos, normas e valores, entre outros. Nesse sentido, este artigo tem como objetivo evidenciar a complexidade das relações entre os elementos do sistema de ED através do pensamento sistêmico. Isto permitirá explicar por que a gestão da ED em centros educativos de educação superior nem sempre tem tido os resultados esperados; e refletir sobre a toma de decisões sob este marco de referência.

Abstract The evolution of distance education (DE) has met various educational needs, thanks to technological progress, teaching initiatives in higher education and educational research. However, many relationships converge between the capacities, the ways of learning, the participation in the decision making by the actors and the agents involved, the norms and values, among others. This article aims to highlight the complexity of the relationships between the elements of the DE system by means of the systemic way of thinking. This will make it possible to explain why the management of DE in higher education institutions has not always had the expected results and to reflect on decision-making under this framework of reference.
