RESUMEN Objetivos. Explorar la frecuencia e impacto de la violencia contra los trabajadores de salud de Argentina y compararlo con el resto de sus pares de Latinoamérica en el contexto de la pandemia por COVID-19. Materiales y métodos. Estudio de corte transversal a través de una encuesta electrónica al personal médico y no médico de Latinoamérica que desempeño tareas asistenciales desde marzo de 2020. Se utilizó una regresión de Poisson para estimar las Razones de Prevalencia crudas (RP) y ajustadas (RPa) con sus respectivos intervalos de confianza al 95%. Resultados. Un total de 3544 participantes de 19 países respondieron la encuesta; 1992 (56,0%) residían en Argentina. Entre los mismos, el 62,9% padeció al menos un hecho de violencia: 97,7% refirió violencia verbal y 11,8% violencia física. El 41,5% de los agredidos padecieron situaciones de violencia al menos una vez por semana. El personal de salud de Argentina vivenció más frecuentemente violencia que los de otros países (62,9% vs. 54,6%, p<0,001), siendo estos eventos más habituales y estresantes (p<0,05). Además, refirieron más frecuentemente haber considerado cambiar sus tareas asistenciales y/o deseos de abandonar su profesión (p<0,001). En la regresión de Poisson, los participantes de Argentina tuvieron una prevalencia de violencia mayor que los trabajadores de salud de la región (14,6%; p<0,001). Conclusiones. Existió una elevada prevalencia de violencia contra el personal de salud de Argentina durante la pandemia por COVID-19. Estos hechos tuvieron un alto impacto negativo entre quienes los padecieron. Nuestros datos sugieren que, esto podría haber sido más frecuente en Argentina respecto de otras regiones del continente.

ABSTRACT Objectives. To explore the frequency and impact of violence against healthcare workers in Argentina and to compare it with the rest of their Latin American peers during the COVID-19 pandemic. Materials and methods. A cross-sectional study was conducted by applying an electronic survey on Latin American medical and non-medical personnel who carried out health care tasks since March 2020. We used Poisson regression to estimate crude (PR) and adjusted (aPR) Prevalence Ratios with their respective 95% confidence intervals. Results. A total of 3544 participants from 19 countries answered the survey; 1992 (56.0%) resided in Argentina. Of these, 62.9% experienced at least one act of violence; 97.7% reported verbal violence and 11.8% physical violence. Of those who were assaulted, 41.5% experienced violence at least once a week. Health personnel from Argentina experienced violence more frequently than those from other countries (62.9% vs. 54.6%, p<0.001), and these events were more frequent and stressful (p<0.05). In addition, Argentinean health personnel reported having considered changing their healthcare tasks and/or desired to leave their profession more frequently (p<0.001). In the Poisson regression, we found that participants from Argentina had a higher prevalence of violence than health workers from the region (14.6%; p<0.001). Conclusions. There was a high prevalence of violence against health personnel in Argentina during the COVID-19 pandemic. These events had a strong negative impact on those who suffered them. Our data suggest that violence against health personnel may have been more frequent in Argentina than in other regions of the continent.

ABSTRACT Objective. To report the progress in Peru, since June 2019, in the implementation of the World Health Organization Global Initiative for Childhood Cancer using the CureAll framework, which can be replicated in low- and middle-income countries. Methods. A mixed method was used of participatory and documentary evaluation. The participatory evaluation included stakeholders from various government institutions, nonprofit organizations, and international partners. The documentary aspect consisted of a review of data on the regulatory environment, national projects, and interventions implemented. The Ministry of Health engaged more than 150 participants to form working committees, which have developed policy and regulatory documents to strengthen care services. Results. Achievements include a decrease in the national treatment abandonment rate from 18.6% to 8.5%, the approval of the Childhood Cancer Law, improvements in the management of patients with febrile neutropenia, and a reduction in rates of events of clinical deterioration and mortality of hospitalized patients. The Cure All implementation framework allows local teams to implement specific strategies and monitor early outcomes in pediatric oncology. Conclusions. The results obtained reflect the teamwork, the leadership of the authorities, the technical support of professionals, and the support of involved organizations. Further actions will be needed to guarantee sustainability, and monitoring tools are needed to assure success in the planned activities.

Abstract Objective: Oral Squamous Cell Carcinoma (OSCC) is conventionally treated by surgical resection, and positive surgical margins strongly increase local recurrence and decrease survival. This study aimed to evaluate whether a Three-Dimensional Segmentation (3DS) image of OSCC confers advantage over Multiplanar Reconstruction (MPR) of OSCC using images of computed tomography scan in surgical planning of tumor resection. Methods: Twenty-six patients with locally advanced OSCC had tumor morphology and dimensions evaluated by MPR images, 3DS images, and Surgical Pathology Specimen (SPS) analyses (gold standard). OSCC resection was performed with curative intent using only MPR images. Results: OSCC morphology was more accurately assessed by 3DS than by MPR images. Similar OSCC volumes and dimensions were obtained when MPR images, 3DS images and SPS measurements were considered. Nevertheless, there was a strong correlation between the OSCC longest axis measured by 3DS and SPS analyses (ICC = 0.82; 95% CI 0.59–0.92), whereas only a moderate correlation was observed between the longest axis of OSCC measured by MPR images and SPS analyses (ICC = 0.51; 95% CI 0.09–0.78). Taking only SPS with positive margins into account, MPR images and 3DS images underestimated the tumor’s longest axis in eight out of 11 (72.7%) and 5 out of the 11 (45.5%) cases, respectively. Conclusion: Our data present preliminary evidence that 3DS model represents a useful tool for surgical planning of OSCC resection, but confirmation in a larger cohort of patients is required.

Resumo A glomerulonefrite rapidamente progressiva é uma emergência médica, com mortalidade em torno de 20%. É caracterizada por glomerulonefrite com crescentes e perda progressiva da função renal, hematúria e proteinúria. Sua classificação é dada pela detecção na imunofluorescência de anticorpos anti-membrana basal glomerular (Anti-MBG), imunocomplexos, ou padrão pauci-imune. Sua etiologia deve ser baseada em resultados clínicos, perfil imunológico, idade, sexo e características histopatológicas. Apresentamos o caso de uma mulher de 27 anos de idade com sintomas consistentes com uma glomerulonefrite rapidamente progressiva e achados de biópsia de uma nefropatia com padrão full-house que evoluiu com desfecho fatal precoce. A associação de um padrão full-house, que possui uma baixa incidência, com um perfil autoimune para lúpus eritematoso sistêmico negativo torna este um caso raro. Foi diagnosticado vasculite associada ao ANCA com doença renal com padrão full-house. Por se tratar de uma condição incomum com até 3% de apresentação e poucos registros na literatura, destacamos a importância de seu relato e sua contribuição para a literatura.

Abstract Rapidly progressive glomerulonephritis is a medical emergency, with mortality around 20%. It is characterized by crescent glomerulonephritis and progressive loss of kidney function, hematuria, and proteinuria. Its classification is given by immunofluorescence detection of antibodies against glomerular basement membrane (Anti-MBG), immunocomplexes, or pauci-immune pattern. Its etiology should be based on clinical findings, immunological profile, age, sex, and histopathological characteristics. We present a case of a 27-year-old woman with symptoms consistent with rapidly progressive glomerulonephritis and biopsy findings of a full-house kidney nephropathy, with an early fatal outcome. An association of low incidence, as it is a case with a full-house pattern, and an autoimmune profile for negative systemic lupus erythematosus makes this a rare case. ANCA-associated vasculitis with full-house kidney disease was diagnosed, an unusual condition with up to 3% presentation and few reports in the literature, highlighting the importance of its reporting and contribution to the literature.

ABSTRACT Introduction: The profession's regulatory instruments declare the need to include in the emergency services rehabilitation nurses. In this context, an attempt was made to understand the relevance of the contribution of rehabilitation nurses in the current context in emergency services. Methodology: Qualitative, exploratory and descriptive study, using a focus group as a data collection technique, in an intentional sample of eight expert nurses, four of them in the urgency area and four rehabilitation nurses. Results: Two categories emerge: organization of care, with greater relevance attributed to the subcategories teams and organization of the emergency services, with a weight of 18.0% and 12.8%, respectively, in the totality of the discourse; and provision of care, with greater relevance attributed to the subcategories prevention of complications and training of the person / caregiver for discharge, with a weight of 11.9% and 11.6%, respectively. Discussion: Corroborating the findings of this study, evidence highlights the relevance of rehabilitation nursing in the domains of leadership and interprofessional care, with gains also perceived at respiratory and motor levels. Conclusion: The participants identify gains from the integration of rehabilitation nurses in emergency services in the organization of the service and in the provision of care, highlighting the complementarity of common and specific competences, thus meeting the profession's references on the need to provide these contexts for these professionals.

ABSTRACT Invasive pulmonary aspergillosis is a condition that mainly occurs in immunosuppressed patients, and it has a high mortality rate. Pneumonia caused by Pneumocystis jirovecii is a potentially lethal opportunistic infection affecting immunosuppressed patients with different etiology. Coinfection by Aspergillus and P. jirovecii in immunocompetent patients is unusual. We report a case of a patient with no common causes of immunosuppression who developed pneumonia coinfection caused by Aspergillus fumigatus and Pneumocystis jirovecii.

RESUMEN La aspergilosis pulmonar invasiva es una enfermedad presente principalmente en pacientes inmunocomprometidos con alta carga de mortalidad. La neumonía por Pneumocystis jirovecii es una infección oportunista potencialmente mortal que afecta a pacientes inmunocomprometidos por diversas etiologías. La coinfección por estos patógenos en pacientes inmunocompetentes es inusual. Reportamos un caso de un paciente sin las causas tradicionales de inmunocompromiso en el desarrollo de una neumonía en coinfección por Aspergillus fumigatus y Pneumocystis jirovecii.

ABSTRACT Bud rot (BR) caused by Phytophthora palmivora and lethal wilt (LW) whose causal agent is unknown, are two diseases currently posing a threat to the oil palm ( Elaeis guineensis . Jacq) industry. BR, first reported in 1964, has destroyed more than 85,000 ha. LW, first reported in 1994 in the Llanos Orientales in Colombia, has destroyed more than 5,000 ha. Chlorophyll a fluorescence is useful as a provider of information about the efficiency of the photosynthetic process when plants are subjected to biotic or abiotic stresses. Oil palms affected by BR and LW showed anomalies in the photosynthetic system, manifested by reductions in Fv / F M and ΦPSII. Changes in ΦPSII, variable fluorescence yield ( Fv ) and maximum fluorescence in light-adapted leaves ( F M ’ ) were observed from the start of BR infection. The most sensitive and early indicators of LW disease were leaf temperature and basal fluorescence ( F 0 ). Fv/F 0 significantly changed in diseased palms, indicating problems with movement of electrons through the electron transport chain. Leaf temperature changed in response to both diseases, but variation was greater in LW. We concluded that damage to the photochemical system caused by the diseases affected the processes by which the plant captures and transports energy, causing a physiological imbalance in the plant reflected in the observed variations in chlorophyll a fluorescence and leaf temperature. The two parameters began to change early in the onset of BR and before visual symptoms appeared in LW, which is very important to the management of both diseases, the foundation of which is early detection.

The first fossil remains of vertebrates, invertebrates, plants and palynomorphs of the Chorrillo Formation (Austral Basin), about 30km to the SW of the town of El Calafate (Province of Santa Cruz), are described. Fossils include the elasmarian (basal Iguanodontia) Isasicursor santacrucensis gen. et sp. nov., the large titanosaur Nullotitan glaciaris gen. et sp. nov., both large and small Megaraptoridae indet., and fragments of sauropod and theropod eggshells. The list of vertebrates is also composed by the Neognathae Kookne yeutensis gen. et sp. nov., two isolated caudal vertebrae of Mammalia indet., and isolated teeth of a large mosasaur. Remains of fishes, anurans, turtles, and snakes are represented by fragmentary material of low taxonomical value, with the exception of remains belonging to Calyptocephalellidae. On the other hand, a remarkable diversity of terrestrial and freshwater gastropods has been documented, as well as fossil woods and palinological assemblages. The Chorrillo Formation continues south, in the Las Chinas River valley, southern Chile, where it is called Dorotea Formation. Both units share in their lower two thirds abundant materials of titanosaurs, whose remains cease to appear in the upper third, registering only elasmarians (Chorrillo Formation) and hadrosaurs (Dorotea Formation). Above both units there are levels with remains of invertebrates and marine reptiles. It is striking that the dinosaurs of the lower two thirds of the Chorrillo and Dorotea formations are represented by large basal titanosaurs and Megaraptoridae coelurosaurs, being the Saltasaurinae and Aeolosaurinae sauropods and Abelisauridae theropods totally absent. In contrast, these taxa are dominant components in sedimentary units of central and northern Patagonia (e.g., Allen, Los Alamitos, La Colonia formations). Such differences could reflect, in part, a greater antiquity (i.e., late Campanian-early Maastrichtian) for the Chorrillo fossils, or, more probably, different environmental conditions. Thus, knowledge of the biota of the southern tip of Patagonia is expanded, particularly those temporarily close to the K-Pg boundary.

Se describen los primeros restos fósiles de vertebrados, invertebrados, plantas y palinomorfos de la Formación Chorrillo (Cuenca Austral), aflorante unos 30km al SW de la localidad de El Calafate (Provincia de Santa Cruz). Los fósiles de dinosaurios no avianos incluyen el elasmariano (Iguanodontia basal) Isasicursor santacrucensis gen. et sp. nov., el titanosaurio gigante Nullotitan glaciaris gen. et sp. nov., Megaraptoridae indet. de tamaños pequeño y grande, y fragmentos de cáscaras de huevo pertenecientes a saurópodos y terópodos. La lista de vertebrados se compone también del Neognathae Kookne yeutensis gen. et sp. nov., dos vértebras caudales aisladas de Mammalia indet., y dientes aislados de un mosasaurio de gran tamaño. Han sido colectados también restos de peces, anuros, tortugas y serpientes los cuales están representados por material fragmentario de escaso valor taxonómico, con la excepción de restos pertenecientes a Calyptocephalellidae. Por otra parte, ha sido documentada una notable diversidad de gasterópodos terrestres y dulceacuícolas, así como leños fósiles y asociaciones palinológicas. La Formación Chorrillo se continúa hacia el sur, en el valle del río Las Chinas, Chile, en donde es denominada Formación Dorotea. Ambas unidades comparten en sus dos tercios inferiores abundante material de titanosaurios, cuyos restos dejan de aparecer en el tercio superior, registrándose solo elasmarianos (Fm Chorrillo) y hadrosaurios (Fm Dorotea). Por encima de ambas unidades existen niveles con restos de invertebrados y reptiles marinos. Llama la atención que los dinosaurios de los dos tercios inferiores de las formaciones Chorrillo y Dorotea estén representados por titanosaurios basales de gran tamaño y celurosaurios Megaraptoridae, estando ausentes los Saltasaurinae, Aeolosaurinae y Abelisauridae, los cuales son componentes dominantes en las unidades sedimentarias del Maastrichtiano de la provincia de Chubut y del norte patagónico (p.ej., formaciones Allen, Los Alamitos y La Colonia, por ejemplo). Estas diferencias podrían reflejar, en parte, una mayor antigüedad (i.e., Campaniano tardío -Maastrichtiano temprano) para los fósiles de Chorrillo. Se amplía así el conocimiento de las biotas del extremo sur de Patagonia, en particular de aquellas temporalmente cercanas al límite K-Pg.

Resumo Objetivo Investigar a associação entre a exposição maternal ao álcool e o baixo peso ao nascer. Método A busca na literatura ocorreu em janeiro de 2017 nas seguintes bases de dados eletrônicas: Medline, Embase, LILACS, SciELO, Web of Science, Scopus, CINHAL, Proquest, e PsychInfo. A estratégia de busca utilizou os seguintes termos: alcohol drinking, binge drinking, alcohol-related disorders, alcoholism, alcohol addiction/use/ abuse/consumption, light/moderate/social/low drinking, low birthweight, case-control studies, retrospective studies, e cohort studies. Não houve restrição de idioma e ano de publicação. A busca na literatura identificou 2.383 artigos, e depois de analisados conforme os critério de elegibilidade, foram incluídos na revisão sistemática 39 estudos, e 38 estudos foram incluídos na metanálise. Resultados A amostra foi composta por 497.023 gestantes. O consumo materno de álcool foi associado ao baixo peso ao nascer entre os estudos de coorte retrospectiva (risco relativo [RR] = 1,37; IC [intervalo de confiança] 95%: 1,10-1,77; I2 = 98,4%; p < 0,01). Os estudos de coorte prospectiva (RR = 1,11; IC95%: 0,98-1,25; I2 = 81,5%; p < 0,01) e caso-controle (razão de chances [OR, na sigla em inglês] = 1,16; IC95%: 0,68-1,97; I2 = 61,2%; p = 0,05) não apresentaram associação entre o consumo e o desfecho. Não foi identificado viés de publicação, e a metarregressão mostrou que o tamanho da amostra influenciou a heterogeneidade entre os estudos de coorte prospectiva. Na análise por subgrupo, houve diferenças entre os grupos por tamanho de amostra, por tipo de ajuste e por ano de publicação. Conclusão Não encontramos associação entre o consumo e o baixo peso ao nascer em todas as análises por subgrupo. Além disso, encontramos alta heterogeneidade entre os estudos primários, e isto se deve possivelmente às diferenças metodológicas na condução destes estudos.

Abstract Objective To investigate the relationship between maternal exposure to alcohol and low birthweight (LBW). Methods The literature search was performed in January 2017 using the following electronic databases: Medline, Embase, LILACS, SciELO, Web of Science, Scopus, CINHAL, Proquest, and PsychInfo. The search strategy used the following terms: alcohol drinking, binge drinking, alcohol-related disorders, alcoholism, alcohol addiction/ use/abuse/consumption, light/moderate/social/low drinking, low birthweight, case-control studies, retrospective studies, and cohort studies. No restrictions regarding language or publication date were considered. The literature search yielded 2,383 articles, and after screening and eligibility assessment, 39 articles were included in the systematic review, and 38 studies were included in the meta-analysis. Results Maternal alcohol consumption was associated with LBWamong retrospective cohort studies (relative risk [RR] = 1.37; 95%CI [confidence interval]:1.10-1.77; I2 = 98.4%; p < 0.01). Prospective cohort studies (RR = 1.11; 95%CI: 0.98-1.25; I2 = 81.5%; p < 0.01), and case-control studies (odds ration [OR] = 1.16; 95%CI: 0.68-1.97; I2 = 61.2%; p = 0.05) showed no association between alcohol and LBW.No publication bias was identified, and the meta-regression showed that the sample size influenced the high heterogeneity among retrospective cohort studies. The subgroup analysis showed differences in association between groups when compared by sample size, type of adjustment, or crude measures and publication year. Conclusions We have not found an association between alcohol consumption during gestation and LBW in the analysis in all of the subgroups. In addition, we have found a high heterogeneity between the primary studies, which is related to methodological differences in the conduction of these studies.

ABSTRACT: The behavior of the Argentine shortfin squid (Illex argentinus) in reaction to a trawl net is reported from images obtained during one fishing tow operated by a commercial trawler in May 2015 in slope grounds off southern Brazil (depth 370-361 m; 33°37’S, 50°49’W). Video analysis utilized criteria to classify the horizontal and vertical distribution of squid in the field of view of the camera, posture (pitch and yaw), squid color patterns, escape reaction, swimming time and use of the tail fin. The monitored bottom trawl operation intercepted dense and patchily distributed schools of I. argentinus that could be observed for brief periods of time swimming ahead of the mouth of the trawl. Individuals were evenly distributed in the water column but concentrated on the center and right sectors of the trawl mouth. Most squids in the path of a trawl tended to swim by jet-propulsion for 10-20 s, tail-first and with regularly spaced fin flaps. Estimated speed (1.24 m s-1) was higher than cruise speed recorded for other ommastrephid squids in nature (0.3 m s-1), possibly reflecting an emergency escape reaction. After a period of sustained swimming ahead of the trawl, squid reacted in different ways including: a) slowing down and swimming into the net tunnel, b) shifting directions to escape through the trawl mouth sides, and c) swimming up, trying to escape over the top trawl panel, sometimes turning around pointing the tail towards the trawl mouth.

RESUMEN El ácaro Tetranychus urticae es considerada una plaga clave en el cultivo de papaya del Valle del Cauca (Colombia) y su control ha sido generalmente con productos químicos sin probar otras alternativas de manejo. Por lo anterior, el objetivo de este estudio fue evaluar en un cultivo de papaya Hibrido Tainung-1, en el municipio de Roldanillo, el efecto de las alternativas: extracto de planta (extracto vegetal de ajo-chile, Alisin®), aceite mineral (complejo de ácidos grasos vegetales, Adimel®), hongo entomopatógeno (Successor®), control químico (spiromesifen, abamectina, fenazaquin), sin manejo (tratamiento control) y prácticas del agricultor (14 aplicaciones de plaguicidas), utilizando un diseño de bloques al azar con tres repeticiones/tratamiento. Se hicieron muestreos cada 8 días midiendo las variables número de hojas/planta, número de hojas infestadas/planta, número de estructuras florales/planta, número de frutos/planta, diámetro del tallo/planta (cada 30 días), población de T. urticae/hoja y rendimiento. Se encontró que las poblaciones de T. urticae /hoja fueron bajas en los tratamientos hongo entomopatógeno (11,978) y control químico (10,548), donde no presentaron diferencias significativas (F>0,05) con respecto a las prácticas del agricultor (3,339); en contraste, las poblaciones del ácaro fueron muy elevadas en los tratamientos extracto de planta (22,086), aceite mineral (20,411) y sin manejo (35,746) con respecto a las prácticas del agricultor. Se presentó una diferencia significativa en todos los tratamientos y prácticas del agricultor para la variable infestación y entre los tratamientos aceite mineral y sin control vs. prácticas del agricultor para número de hojas/planta. Del resto de variables evaluadas no se encontró diferencias significativas entre tratamientos. El hongo entomopatógeno resultó ser la mejor alternativa para un programa de manejo de T. urticae en papaya en el departamento.

ABSTRACT The mite Tetranychus urticae is a key pest in papaya crop in Valle del Cauca (Colombia), and it has been generally controlled with chemical products; other management alternatives have not been used. Therefore, this study aimed to evaluate the effects of alternatives: plant extract (garlic-chili vegetable extract, Alisin®), mineral oil (vegetable fatty acid complex, Adimel®), entomopathogenic fungus (Successor®), chemical control (spiromesifen, abamectin, fenazaquin), untreated (control treatment) and farmer's practices (14 applications of pesticides) in a randomized complete block design with three replications/treatment in a Hybrid Tainung-1 papaya crop in the municipality of Roldanillo. The sampling was done every 8 days by measuring the variables: number of leaves/plant, number of infested leaves/plant, number of floral structures/plant, number of fruits/plant, diameter of stem/plant (every 30 days), population of T. urticae/leaf and yield. It was found that the populations of T. urticae/leaf were low in entomopathogenic fungus (11.978) and chemical control (10.548), with no significant differences (P>0.05) from farmer's practices (3.339). In contrast, the mite populations were very high in plant extract (22.086), mineral oil (20.411) and untreated (35.746), as compared to farmer's practices. There was a significant difference in all treatments for the variable infestation from farmer's practices, and the number of leaves/plant in mineral oil and untreated treatment was significantly different from farmer's practices. No significant differences were found between the treatments in the rest of the evaluated variables. The entomopathogenic fungus turned out to be the best alternative for a management program of T. urticae in papaya in this region.
