Resumen Introducción: En 1994, Claudio Bassi relató un caso de tratamiento médico de la necrosis pancreática infec tada (NPI); luego desde 1996 se publicaron numerosos artículos de serie de casos con tratamiento solo con antibióticos con buenos resultados. Objetivos: Presentar nuestra experiencia en el manejo de la necrosis pancreática infectada con antibióticos (sin drenaje). Métodos: Revisamos retrospectivamente los pacientes con diagnóstico de NPI desde enero de 2018 a octubre del 2020, enfocándonos en aquellos casos que se trata ron de forma conservadora (soporte hidroelectrolítico, nutricional y antibióticos). El diagnóstico se realizó ob servando gas en el retroperitoneo por TC asociado o no a deterioro clínico del paciente con necrosis pancreática sin otro foco. No se realizó punción aspiración con aguja fina (PAAF). Resultados: Identificamos 25 pacientes con diag nóstico de NPI. Once fueron tratados de forma conser vadora. Según la clasificación de Atlanta, modificada en 2012, 3 casos fueron clasificados de forma grave y el resto moderadamente grave. Todos recibieron antibióticos al menos durante 3 semanas. Ninguno requirió nutrición parenteral. El promedio de estan cia hospitalaria fue de 38 días. Tres pacientes fueron readmitidos. A 8 se les realizó colecistectomía luego de haber resuelto el cuadro; los restantes ya estaban colecistectomizados. No hubo muertes en esta serie. Conclusiones: La NPI puede ser tratada de forma con servadora sin drenaje con buenos resultados en casos seleccionados.

Abstract Introduction: In 1994, Claudio Bassi reported a case of medical treatment for infected pancreatic necrosis (IPN); then since 1996 numerous articles of case series were published with treatment only with antibiotics with good outcomes. Objectives: To present our experience in the mana gement of patients with IPN with antibiotics (without drainage). Methods: We retrospectively reviewed cases with a diagnosis of IPN from January 2018 to October 2020, focusing on those cases that were treated conservatively (hydro-electrolyte, nutritional support and antibiotics). The diagnosis was made by observing gas in the re troperitoneum by CT or by clinical deterioration of the patient with pancreatic necrosis without another focus. Fine needle aspiration was not performed. Results: We identified 25 patients with a diagnosis of IPN; eleven were treated conservatively. According to Atlanta, modified in 2012, 3 were classified severely and the rest moderately severe. All received antibiotics for at least 3 weeks. None required parenteral nutrition. The mean hospital stay was 38 days. Three patients were readmitted. 8 underwent cholecystectomy after having resolved the condition; the rest were already cholecys tectomized. There were no deaths in this series. Conclusions: IPN can be treated conservatively without drainage with good results in selected cases.

Abstract This study aimed to evaluate the effect of an elastomeric urethane monomer (Exothane-24) in different concentrations on physicochemical properties, gap formation, and polymerization shrinkage stress of experimental resin composites. All experimental composites were prepared with 50 wt.% of Bis-GMA and 50 wt.% of TEGDMA, to which 0 wt.% (control), 10 wt.%, 20 wt.%, 30 wt.%, and 40 wt.% of Exothane-24 were added. Filler particles (65 wt.%) were then added to these resin matrixes. Ultimate tensile strength (UTS: n = 10), flexural strength (FS: n = 10), flexural modulus (FM: n = 10), hardness (H: n = 10), hardness reduction (HR: n = 10), degree of conversion (DC: n = 5), gap width (GW: n = 10), and polymerization shrinkage stress in Class I (SS-I: n = 10) and Class II (SS-II: n = 10) simulated configuration. All test data were analyzed using one-way ANOVA and Tukey’s test (α = 0.05; β= 0.2). Exothane-24 in all concentrations decreased the H, HR, DC, GW, SS-I, and SS-II (p < 0.05) without affecting the UTS, and FS (p > 0.05). Reduction in FM was observed only in the Exothane 40% and 30% groups compared to the control (p < 0.05). Exothane-24 at concentrations 20% and 30% seems suitable since it reduced GW and polymerization SS without affecting the properties of the composite resins tested, except for H.

Resumo Este estudo teve como objetivo avaliar o efeito de um monômero elastomérico de uretano (Exothane-24) em diferentes concentrações em propriedades físico-químicas, formação de fenda e tensão de contração de polimerização de resinas compostas experimentais. Todos os compósitos experimentais foram preparados com 50% em peso de Bis-GMA e 50% em peso de TEGDMA, nos quais 0% (controle), 10%, 20%, 30% e 40% em peso de Exothane-24 foram adicionados. Partículas de carga (65% em peso) foram então adicionadas as matrizes resinosas. Resistência coesiva (RC: n = 10), resistência à flexão (RF: n = 10), módulo de flexão (MF: n = 10), dureza (D: n = 10), redução de dureza (RD: n = 10), grau de conversão (GC: n = 5), largura de fenda (LF: n = 10) e tensão de contração de polimerização em simulações de cavidades Classe I (TC-I: n = 10) e Classe II (TC-II: n = 10). Todos os dados do teste foram analisados usando one-way ANOVA e teste de Tukey (α = 0,05; β = 0,2). O Exothane-24 em todas as concentrações diminuiu a D, RD, GC, LF, TC-I e TC-II (p < 0,05) sem afetar o RC e RF (p > 0,05). A redução da MF foi observada apenas nos grupos Exothane 40% e 30% em relação ao controle (p < 0,05). O Exothane-24 nas concentrações de 20% e 30% pareceu ser adequado, pois reduziu LF e TC de polimerização sem afetar as propriedades das resinas compostas testadas, exceto para D.

Abstract Non-timber forest products are transcendental for the well-being of rural households, rural and suburban communities, they provide them with priority goods and services for their subsistence. The present work tries to identify the use of non-timber forest resources for the elaboration of handicrafts in the community of Malinalco, State of Mexico; as well as register the habitat where the resources come from and the legal and economic framework for the use of said resources. Through the ethnographic method, the instrument for obtaining the information, which was a questionnaire, was carried out and validated. Key informants were obtained, and interviews were conducted. During five months through semi-structured interviews with three artisans and 17 artisans from the community, a list of 11 different crafts made and marketed in the Malinalco community was obtained. Forest diversity was 15 species, 19 genera and 12 families; of which 4 taxa were identified at the generic level. The most used species are Agave sp. Crescentia alata Kunth and Jacaranda mimosifolia D. Don. The most representative families were Bignoniaceae and Asparagaceae. 43.9% were tree species, and 22% climbers, obtained from the low deciduous forest (58.3%) or from home gardens (18.75%). Regarding the parts used, 46.34% correspond to fruits and 17.07% to seeds. The knowledge about the use of flora in the elaboration of handicrafts allowed us to know the importance of the low deciduous forest and family gardens to obtain resources for the elaboration and commercialization of handicrafts in the community of Malinalco, State of Mexico.

ABSTRACT CROPWAT is a model that uses water balance to study the water factor and productivity in production systems. In this sense, this study aimed to calibrate the CROPWAT for modeling rainfed and irrigated soybean production systems. Climate and soil data from a soybean-producing region in the south of Mato Grosso do Sul, Brazil, were used to implementing simulations in nine agricultural years, and crop shortfalls were calculated and compared with reference data. Statistical indices were applied to evaluate the performance of the model in its calibration. For validation, two field trials with 12 cultivars were implemented under irrigation and rainfed and the mean productivity in each water management was compared with the CROPWAT estimate by Student’s t-test. Accuracy (r) was 0.976 (“very strong”), precision (r2) was equivalent to 95.3%, and the indices of agreement (d) and performance (c) were considered excellent (0.95 and 0.93, respectively) in the calibration. Validation demonstrated that the hypothesis that CROPWAT correctly estimated soybean productivity under irrigated and rainfed systems cannot be rejected at 1 or 5% significance levels.

Abstract The spatial gradients created after the installation of large reservoirs produce a great diversity of biotopes, which affects the distribution and structuring of aquatic communities, mainly fish. Thus, we hypothesized that the fishes living in the lotic stretch (river zone, closest to the natural environment) of the reservoir would have lower overlap and higher niche breadth than fishes living in the lentic stretch. Samples were collected in six sections (lentic and lotic) of the Chavantes Reservoir, middle Paranapanema River. A total of 1478 individuals distributed in 13 species were sampled in both stretches. Many resources were acquired by species, and we observed that nine species present significant differences when comparing the two stretches. Furthermore, only \emph{Schizodon nasutus

ABSTRACT The objective of this study was to evaluate the effect of either a limited forage intake or concentrate supplementation prior to the adaptation to high-concentrate diets on dry matter intake, ruminal pH, bacteria, and protozoa of Nellore cattle. The experiment was designed as a two 3×3 Latin square, and six cannulated Nellore steers were used. Each experimental period was composed by three feeding phases: pre-adaptation (14 days), adaptation (12 days), and finishing (seven days) diet, in a total of 33 days per period. The steers were assigned to one of three pre-adaptation dietary treatments: control (Tifton hay fed ad libitum + mineral supplement), restriction (Tifton hay fed at 1.4% of BW + mineral supplement), and concentrate (Tifton hay fed ad libitum + 0.5% of BW of a mix of concentrate feedstuffs and mineral supplement). The adaptation period consisted of two adaptation diets, which contained 72 and 79% concentrate for six days each. The finishing diet contained 86% concentrate. During the pre-adaptation phase, restricted cattle had higher pH than concentrate-fed cattle. There was a reduction in M. elsdenii relative population in cattle from either restriction or concentrate groups. During adaptation and finishing phases, cattle from concentrate group had smaller F. succinogenes populations compared with the control group. The previous nutritional backgrounds impact ruminal microbiota during adaptation and finishing phases without causing any negative effect on ruminal pH. Feeding concentrate prior to the adaptation positively impacted the transition to high-concentrate diets and promoted increased dry matter intake.

Abstract As a result of human activities and natural dispersal, exotic species can be brought to new areas, where they become established and spread, becoming invaders. These species are responsible for the loss of biodiversity and cause ecosystemic harm throughout the world. In this paper, we report the rapid, broad geographic expansion of the invasive fly Drosophila nasuta in Brazil. An 84% increase was found in its area of occupation in the country compared to previous studies. The present data reveal its arrival to the Pantanal wetlands in a location more than one thousand kilometers from the closest previous record in the Cerrado biome. We present the first record of D. nasuta in the Atlantic Forest in the states of Paraíba and Bahia. We report its introduction in the Amazon Forest in the state of Amazonas approximately 700 kilometers from previous records. The relative abundance of D. nasuta in this biome increased fivefold in comparison to a previous study. In the first decade of invasion in Brazil, D. nasuta has already colonized more than half of the country. The present data reveal its invasive potential and underscore the importance of following up the possible negative effects of this biological invasion.

ABSTRACT Dientamoeba fragilis is a protozoan that parasitizes the large intestine of humans and domestic animals. To date, some aspects regarding D. fragilis life cycle, including hosts, reservoirs, infection mechanism, among others, are not yet clear. Swine are considered natural hosts for this protozoan, therefore their close contact with humans promotes its zoonotic transmission. In Colombia there are no studies on the presence of D. fragilis in animal hosts, including pigs, and data about other intestinal protozoa are scarce. The objective was to determine the prevalence of intestinal protozoan, including D. fragilis, in pigs raised in a farm from a rural area of Medellin (Andean region of Colombia). Fecal samples from 70 pigs in prefattening stage were collected. Direct fecal smear examination, trichrome and modified Ziehl-Neelsen stain were used in the study. Univariate analysis (frequency distribution and central tendency measures) and bivariate analysis were used to explore risk factors. Dientamoeba fragilis was found in 13% of the evaluated fecal samples. Other parasites detected included: Entamoeba spp. (66%), Blastocystis spp. (64%), Balantioides coli (36%), Cryptosporidium spp. (36%), Iodamoeba butschlii (17%), coccidias (4%), and Giardia spp. (1,4%). This is the first report of D. fragilis in swine in Colombia, and the high prevalence of other pathogen protozoa was also observed, which corroborates the role of pigs as important reservoirs for human infections. Studies focused on the evaluation of both swine and swine-exposed farm workers should be done in order to know the dynamics of transmission of this parasite.

RESUMEN Dientamoeba fragilis es un protozoário que parasita el intestino grueso del hombre y animales domésticos. Hasta el momento, aún no son claros aspectos de su ciclo de vida, como el rango de hospedadores, reservorios, mecanismo de infección, entre otros. Se postula que el cerdo es un hospedador natural para este protozoario y que, debido a su cercanía con el humano, podría facilitar una transmisión zoonótica. En Colombia no existen a la fecha estudios sobre la presencia de D. fragilis en hospedadores animales, incluidos los cerdos, y los datos sobre la prevalencia de otros protozoarios intestinales en estos animales son escasos. El objetivo fue determinar la frecuencia de protozoarios intestinales, incluyendo D. fragilis, en cerdos de una granja tecnificada de una zona rural de Medellín (región Andina de Colombia). Se recolectaron muestras de materia fecal de 70 cerdos en etapa de preceba, que fueron evaluadas mediante examen directo, tinción tricrómica y Ziehl-Neelsen modificado. Se realizaron análisis univariados con medidas de frecuencia relativa y tendencia central y análisis bivariados para la exploración de factores de riesgo. Se detectó la presencia de D. fragilis en un 13% de las muestras y de otros parásitos como Entamoeba spp. (66%), Blastocystis spp. (64%), Balantioides coli (36%), Cryptosporidium spp. (36%), Iodamoeba butschlii (17%), coccidias (4%) y Giardia spp. (1,4%). En este primer reporte de D. fragilis en cerdos en Colombia se observó la alta prevalencia de otros protozoarios patógenos, lo que corrobora el papel de los cerdos como importantes reservorios de infecciones humanas. Estudios sobre la presencia de este protozoario tanto en cerdos como en el personal encargado de su manejo contribuirían al conocimiento sobre su dinámica de transmisión.

ABSTRACT Objective: To evaluate the precipitating factors of diabetic ketoacidosis (DKA) in patients with type 1 diabetes hospitalized through the emergency department of a tertiary hospital. Materials and methods: Individuals with type 1 diabetes hospitalized for DKA from January 2005 to March 2010 (first period [P1], n = 75) and from April 2010 to January 2017 (second period [P2], n = 97) were identified through a query of electronic medical records. Data were collected by reviewing medical records. Only the first hospitalization of each participant in each period was included. Results: In P2, 44 patients (45.4%) were women, mean age was 26.2 ± 14.5 years, and 74 patients (76.3%) had a previous diagnosis of type 1 diabetes. Only 1 patient had glycated haemoglobin (HbA1c) below 64 mmol/mol (8.0%). Most patients (62.2%) had had a previous episode of DKA. In P1, non-adherence was the main cause of DKA (38.7%), followed by infection (24.0%). In P2, these rates were 34.0% and 24.7%, respectively; no statistical difference was observed between the two study periods (p = 0.790). Conclusion: Over time, non-adherence remained the main precipitating factor of DKA, followed by infection, and no significant difference was observed between the two study periods. Elevated HbA1c, outside the therapeutic range, indicates suboptimal diabetes care and may explain, at least in part, poor adherence as a precipitating factor of decompensation. Health strategies, such as improved self-management of type 1 diabetes, may contribute to a future reduction in DKA episodes.

Objective: To systematically review the literature focusing on obstetric and perinatal outcomes in women with previous or current eating disorders (EDs) and on the consequences of maternal EDs for the offspring. Methods: The study was performed following the systematic review and meta-analysis (PRISMA) statement. PubMed, SciELO, and Cochrane databases were searched for non-interventional studies published in English or Portuguese from January 1980 to December 2020. Risk of bias was assessed using the Methods guide for effectiveness and comparative effectiveness reviews (American Agency for Healthcare Research and Quality). Results: The search yielded 441 records, and 30 articles were included. The psychiatric outcome associated with EDs in women was mainly perinatal depression. The most prevalent obstetric outcomes observed in women with EDs were vomiting, hyperemesis, bleeding, and anemia. Most studies found maternal anorexia nervosa and bulimia nervosa to be associated with low birth weight and slow fetal growth. Women with binge EDs delivered children with increased birth weight. Of the 30 studies included, methodological quality was good in seven, fair in eight, and poor in 15 studies. Conclusion: A considerable body of evidence was reviewed to assess obstetric and perinatal outcomes in EDs. Acute and lifetime EDs, especially if severe, correlated with poor perinatal, obstetric, and neonatal outcomes. Obstetricians and general practitioners should be vigilant and screen for EDs during pregnancy.

The objective of the study was to determine the outcomes HPB procedures during the COVID-19 pandemic and compare results to the previous year. Methods: IRB approved study of HPB procedures (April, 2020-November, 2020). Primary endpoints: Thirty-day surgical morbidity/mortality, including COVID-19 infection. Secondary endpoints: Comparison between 2019 and 2020 procedures. Results: Twenty-five patients were included. In 2020, HPB procedures decreased 31.6%. About 60% developed complications (Clavien-Dindo Grade III, 20%). Three patients developed post-operative COVID-19 infection (two deaths: 66% COVID-19 mortality). When compared to the previous year, there were more emergency cases, ventilator-assisted patients (p < 0.05) and pre-operative acute renal failure (p = 0.06). Clavien-Dindo complication grades were higher in 2020. Thirty-day mortality was also higher (16% vs. 5.6%). Conclusion: HPB surgical activity was negatively influenced by COVID-19 on 30-day morbidity/mortality. HPB patients who developed post-operative COVID-19 infection had a complicated course with significant mortality.

Resumo O desenvolvimento de um sistema de criação em cativeiro para as espécies de gambá do Caribe amplamente caçadas, Didelphis marsupialis insularis, pode auxiliar bastante no manejo e conservação dessa espécie nos neotrópicos. Embora essa espécie possua características ideais para a criação em cativeiro nessa região (tolerância a altas temperaturas e umidade, alta taxa de reprodução e resistência a doenças), alguns fatores, como o seu comportamento agressivo e informações limitadas sobre seu comportamento reprodutivo, impediram o desenvolvimento de um sistema para D. m. insularis. O presente estudo descreve um sistema de criação e o comportamento reprodutivo dessa espécie em condições de cativeiro. Seis gambás adultos (1 macho e 5 fêmeas) foram mantidos para reprodução durante um período de 10 meses. O tamanho da ninhada em bolsa foi em média de 5 ± 2,5 com um intervalo de 2 a 8. A duração da gestação foi de 13,25 ± 0,96 dias, e 4 ninhadas (n = 23) foram desmamadas com sucesso de 11 a 13 semanas. Verificou-se que o macho D. m. insularis exibe comportamentos de interesse que podem servir como indicadores de receptividade da fêmea, e, em geral, essa espécie pode ser criada com sucesso em condições de cativeiro nos neotrópicos.

Abstract Developing a captive breeding system for the widely hunted Caribbean species of opossum Didelphis marsupialis insularis can greatly aide in the management and conservation of this species in the neo-tropics. Although this species possesses ideal traits for captive breeding in this region (tolerance to high heat and humidity, high reproductive rate, and resistance to disease), challenges due to its aggressive behaviour and limited information on its breeding behaviour have prevented a system from being developed for this species. The present study describes a breeding system, and the reproductive behaviour of this species under captive conditions. Six (1 male; 5 females) adult opossums were maintained and managed for breeding over a ten (10) month period. Pouch litter sizes averaged 5±2.5 with a range of 2 to 8. Gestation length was found to be 13.25±0.96 days and 4 litters (n=23) were successfully weaned at 11-13 weeks. It was found that the male D. m. insularis exhibits behaviours of interest that can serve as indicators for receptivity of the female, and overall, that this species can be successfully reared and bred under captive conditions in the neo-tropics.

Resumo O objetivo deste estudo é avaliar os termos da equação da tendência da energia cinética do distúrbio (K’) nas previsões de 24 h e 48 h dos modelos regionais BRAMS, WRF e ETA. Estes modelos foram integrados operacionalmente no Centro de Previsão de Tempo e Estudos Climáticos (CPTEC). O período de avaliação foi de 1 de junho a 31 de agosto de 2016, sendo que o domínio utilizado foi a região da América do Sul. A resolução horizontal dos modelos é de 5 km e a temporal é de 6 horas. As condições iniciais e de contorno foram obtidas do Global Forecast System (GFS) do National Centers for Environmental Prediction (NCEP), com resolução horizontal de 0,25°. Os modelos foram inicializados apenas com a análise das 1200 UTC. Os modelos foram integrados com a versão não-hidrostática, sendo que o WRF utilizou a parametrização cumulus de Kain-Frisch, o ETA a parametrização culumus de Betts-Miller e o BRAMS Grell e Freitas. Em geral, os três modelos subestimam K’ nas latitudes médias, principalmente sobre os oceanos, porém o ETA é o que menos subestima e o WRF o que tem o maior viés negativo. Com relação aos termos de conversão baroclínica e barotrópica, além do termo de convergência do fluxo ageostrófico, os três modelos apresentam um padrão semelhante aos das análises numéricas do GFS.

Abstract The aim of this study is to evaluate the terms of the eddy kinetic energy (K’) equation in the 24 h and 48 h forecasts of the regional models BRAMS, WRF and ETA. These models were operationally integrated at the Weather Forecast and Climate Studies Center (CPTEC). The evaluation period was from June 1 to August 31, 2016 and the domain was the region of South America. The horizontal resolution of the three models is 5 km and the temporal is 6 h. The initial and boundary conditions were obtained from the Global Forecast System (GFS) of the National Centers for Environmental Prediction (NCEP), with a horizontal resolution of 0.25°. The models were initialized only with the analysis of 1200 UTC. The non-hydrostatic version of the three models was run, with WRF using Kain-Frisch cumulus parameterization, ETA Betts-Miller culumus parameterization and BRAMS Grell and Freitas. In general, the three models underestimate K‘ in mid-latitudes, mainly over the oceans, however, ETA is the one that underestimates the least and WRF the most. Regarding the terms of baroclinic and barotropic conversion, in addition to the term of ageostrophic flow convergence, the three models have a similar pattern of these three terms with that of GFS numerical analysis.

Objective: This study translated, culturally adapted, and validated a Brazilian Portuguese version (SCOFF-BR) of the Sick, Control, One Stone, Fat, Food Questionnaire (SCOFF) to screen eating disorders in young adults. Methods: This study used back-translation to culturally adapt the questionnaire according to International Society of Pharmacoeconomics and Outcome Research principles. The SCOFF-BR validation process involved a sample of men and women aged 18-32 years from a university community. After the participants completed the SCOFF-BR questionnaire, pre-trained researchers interviewed them with the Mini International Neuropsychiatric Interview (MINI). The presence of eating disorders was determined according to DSM-5 criteria. Results: Of the 361 subjects, 9.7% had an eating disorder (2.2% anorexia nervosa, 5% bulimia nervosa, and 2.5% binge-eating disorder). Using a cutoff point of two positive responses, we obtained a sensitivity of 80% and a specificity of 71.5%, with an accuracy of 72.3%. The positive and negative predictive values were 23.1% and 97.1%, respectively. Conclusion: This study demonstrated that the Brazilian version of the SCOFF questionnaire presents satisfactory accuracy and reliability to screen eating disorders among young adults in the Brazilian university community.
