Abstract In Argentina, hemolytic uremic syndrome (HUS) caused by Shiga toxin-producing Escherichia coli (STEC-HUS) infection is endemic, and reliable data about prevalence and risk factors have been available since 2000. However, information about STEC-associated bloody diarrhea (BD) is limited. A prospective study was performed during the period October Surveillance; 2018-June 2019 in seven tertiary-hospitals and 18 referral units from different regions, aiming of STEC-HUS cases in the same hospitals and during the same period were also assessed. Twenty-nine (4.1%) of the BD patients were STEC-positive, as determined by the Shiga Toxin Quik Chek (STQC) test and/or the multiplex polymerase chain reaction (mPCR) assay. The highest fre-quencies were found in the Southern region (Neuquén, 8.7%; Bahía Blanca, 7.9%), in children between 12 and 23 month of age (8.8%), during summertime. Four (13.8%) cases progressed to HUS, three to nine days after diarrhea onset. Twenty-seven STEC-HUS in children under 5 years of age (77.8%) were enrolled, 51.9% were female; 44% were Stx-positive by STQC and all by mPCR. The most common serotypes were O157:H7 and O145:H28 and the prevalent geno-types, both among BD and HUS cases, were sfx2a-only or -associated. Considering the endemic behavior of HUS and its high incidence, these data show that the rate of STEC-positive cases is low among BD patients. However, the early recognition of STEC-positive cases is important for patient monitoring and initiation of supportive treatment.
Resumen En Argentina, el síndrome urémico hemolítico asociado a Escherichia coli productor de toxina Shiga (STEC-SUH) es endémico y, desde 2000, de notificación obligatoria. Sin embargo, la información sobre diarrea sanguinolenta (DS) asociada a STEC (DS-STEC) es limitada. Se realizó un estudio prospectivo desde octubre de 2018 hasta junio de 2019 en siete hospitales de tercer nivel y 18 unidades de referencia de diferentes provincias argentinas, con el objetivo de determinar la frecuencia de casos de DS-STEC en 714 niños de 1 a 9 años que tuvieron DS (I) y la tasa de progresión de DS a SUH en dicha cohorte (II). También se evaluó el número y distribución regional de casos de STEC-SUH en los mismos hospitales en dicho período. Veintinueve casos de DS (4,1%) fueron STEC-positivos, determinados por Shiga Toxin Quik Chek (STQC) o PCR múltiple (mPCR). Las frecuencias más altas se encontraron en el sur del área relevada (Neuquén, 8,7%; Bahía Blanca, 7,9%), en niños de 12 a 23 meses (8,8%), en verano. Cuatro casos de DS-STEC (13,8%) progresaron a SUH, de tres a nueve días después del inicio de la diarrea. Se registraron 27 niños con STEC-SUH, estos fueron mayoritariamente <5 anos (77,8%) del sexo femenino (51,9%). El 44% de estos casos fueron Stx-positivos por STQC y todos por mPCR. Los serotipos más comunes fueron O157:H7y O145:H28, y el genotipo predominante fue stx2a, solo o asociado, en DS y SUH. Considerando el comportamiento endémico del SUH y su alta incidencia, estos datos muestran que la tasa de casos de DS-STEC es baja. Sin embargo, su reconocimiento temprano es importante para el seguimiento e inicio del tratamiento de sostén.

RESUMEN Las diarreas y enteropatías congénitas (CODE por su sigla en inglés) son un grupo de trastornos mo- nogénicos que se han descrito en los últimos años. Dentro de las CODE, la mutación del gen de la dia- cilglicerol o-aciltransferasa 1 (DGAT1) es un trastorno enzimático poco común asociado con diarrea crónica grave de aparición temprana. El objetivo es presentar a dos hermanas que consultaron por diarrea crónica, retraso en el crecimiento, vómitos e hipoalbuminemia en la primera infancia. En ambas pacientes se encontró un compuesto hete- rocigota de la mutación del DGAT1. Esta mutación se describió previamente en la población asiática; sin embargo, estas son las dos primeras pacientes en tener esta mutación en la población latinoamericana. Estos dos casos pueden ampliar nuestro conocimiento sobre las diarreas congénitas en general y las características clínicas de los pacientes con mutaciones en DGAT1 en particular.

In this work, the local electrochemical activity of the zones coupled by Friction Stir Welding (FSW) of an Al-Cu-Li alloy was studied and the results were correlated to the microstructural characteristics of each zone. Electrochemical studies were carried out in the zones affected by welding using cyclic voltammetry (CV) and scanning electrochemical techniques (namely, SECM - Scanning Electrochemical Microscopy and LEIS - Local electrochemical impedance spectroscopy). The results showed that the welding joint (WJ) is predominantly cathodic relatively to the heat affected zones (HAZ). The HAZ was always anodic and showed the highest electrochemical activities among the tested ones. The high electrochemical activity of the HAZ was associated with the effect of galvanic coupling between the cathodic region (WJ) and the anodic region (HAZ). In addition, the advancing side (AS) presented increased electrochemical activity compared to the retreating one (RS).

The antifungal potential of volatile organic compounds (VOCs) produced by actinobacterial strains Streptomyces sp. (ACTB-77) and Amycolatopsis sp. (ACTB-290) from the rhizosphere of Caatinga plants against Colletotrichum musae was investigated. VOCs produced by these microorganisms (axenic and co-culture) were investigated using headspace-solid phase micro-extraction (HS-SPME) and gas chromatography-mass spectrometry (GC-MS). Although no exclusive VOC peaks were observed in the co-culture with ACTB-77, the same experiment involving ACTB-290 yielded five new peaks, including two identified alcohols, suggested as bioreductive products of the corresponding ketones by the fungus. Statistical analysis revealed that co-culture ACTB-77/C. musae has a closer similarity to the fungus than to the actinobacteria, while the co culture ACTB-290/C. musae showed closer similarity to the actinobacteria. These confirmed the more pronounced antifungal activity of the ACTB-290 strain, as observed in the fungus growth inhibition experiments. The antifungal activity of ACTB-290 was associated to its sulfur-containing metabolites, while linalool was suggested as responsible for the ACTB-77 activity.

Abstract Background: Patients using immunosuppressive drugs may have unfavorable results after infections. However, there is a lack of information regarding COVID 19 in these patients, especially in patients with rheumatoid arthritis (RA). Therefore, the aim of this study was to evaluate the risk factors associated with COVID 19 hospitalizations in patients with RA. Methods: This multicenter, prospective cohort study is within the ReumaCoV Brazil registry and included 489 patients with RA. In this context, 269 patients who tested positive for COVID 19 were compared to 220 patients who tested negative for COVID 19 (control group). All patient data were collected from the Research Electronic Data Capture database. Results: The participants were predominantly female (90.6%) with a mean age of 53 ±12 years. Of the patients with COVID 19, 54 (20.1%) required hospitalization. After multiple adjustments, the final regression model showed that heart disease (OR =4.61, 95% CI 1.06–20.02. P < 0.001) and current use of glucocorticoids (OR =20.66, 95% CI 3.09–138. P < 0.002) were the risk factors associated with hospitalization. In addition, anosmia was associated with a lower chance of hospitalization (OR =0.26; 95% CI 0.10–0.67, P < 0.005). Conclusion: Our results demonstrated that heart disease and the use of glucocorticoids were associated with a higher number of hospital admissions for COVID 19 in patients with RA. Trial registration: Brazilian Registry of Clinical Trials RBR 33YTQC.

RESUMO Objetivo: Descrever as práticas de ressuscitação volêmica em unidades de terapia intensiva brasileiras e compará-las com as de outros países participantes do estudo Fluid-TRIPS. Métodos: Este foi um estudo observacional transversal, prospectivo e internacional, de uma amostra de conveniência de unidades de terapia intensiva de 27 países (inclusive o Brasil), com utilização da base de dados Fluid-TRIPS compilada em 2014. Descrevemos os padrões de ressuscitação volêmica utilizados no Brasil em comparação com os de outros países e identificamos os fatores associados com a escolha dos fluidos. Resultados: No dia do estudo, foram incluídos 3.214 pacientes do Brasil e 3.493 pacientes de outros países, dos quais, respectivamente, 16,1% e 26,8% (p < 0,001) receberam fluidos. A principal indicação para ressuscitação volêmica foi comprometimento da perfusão e/ou baixo débito cardíaco (Brasil 71,7% versus outros países 56,4%; p < 0,001). No Brasil, a percentagem de pacientes que receberam soluções cristaloides foi mais elevada (97,7% versus 76,8%; p < 0,001), e solução de cloreto de sódio a 0,9% foi o cristaloide mais comumente utilizado (62,5% versus 27,1%; p < 0,001). A análise multivariada sugeriu que os níveis de albumina se associaram com o uso tanto de cristaloides quanto de coloides, enquanto o tipo de prescritor dos fluidos se associou apenas com o uso de cristaloides. Conclusão: Nossos resultados sugerem que cristaloides são usados mais frequentemente do que coloides para ressuscitação no Brasil, e essa discrepância, em termos de frequências, é mais elevada do que em outros países. A solução de cloreto de sódio 0,9% foi o cristaloide mais frequentemente prescrito. Os níveis de albumina sérica e o tipo de prescritor de fluidos foram os fatores associados com a escolha de cristaloides ou coloides para a prescrição de fluidos.
Abstract Objective: To describe fluid resuscitation practices in Brazilian intensive care units and to compare them with those of other countries participating in the Fluid-TRIPS. Methods: This was a prospective, international, cross-sectional, observational study in a convenience sample of intensive care units in 27 countries (including Brazil) using the Fluid-TRIPS database compiled in 2014. We described the patterns of fluid resuscitation use in Brazil compared with those in other countries and identified the factors associated with fluid choice. Results: On the study day, 3,214 patients in Brazil and 3,493 patients in other countries were included, of whom 16.1% and 26.8% (p < 0.001) received fluids, respectively. The main indication for fluid resuscitation was impaired perfusion and/or low cardiac output (Brazil: 71.7% versus other countries: 56.4%, p < 0.001). In Brazil, the percentage of patients receiving crystalloid solutions was higher (97.7% versus 76.8%, p < 0.001), and 0.9% sodium chloride was the most commonly used crystalloid (62.5% versus 27.1%, p < 0.001). The multivariable analysis suggested that the albumin levels were associated with the use of both crystalloids and colloids, whereas the type of fluid prescriber was associated with crystalloid use only. Conclusion: Our results suggest that crystalloids are more frequently used than colloids for fluid resuscitation in Brazil, and this discrepancy in frequencies is higher than that in other countries. Sodium chloride (0.9%) was the crystalloid most commonly prescribed. Serum albumin levels and the type of fluid prescriber were the factors associated with the choice of crystalloids or colloids for fluid resuscitation.

Abstract Background Insects can be found in numerous diverse environments, being exposed to pathogenic organisms like fungi and bacteria. Once these pathogens cross insect physical barriers, the innate immune system operates through cellular and humoral responses. Antimicrobial peptides are small molecules produced by immune signaling cascades that develop an important and generalist role in insect defenses against a variety of microorganisms. In the present work, a cecropin B-like peptide (AgCecropB) sequence was identified in the velvetbean caterpillar Anticarsia gemmatalis and cloned in a bacterial plasmid vector for further heterologous expression and antimicrobial tests. Methods AgCecropB sequence (without the signal peptide) was cloned in the plasmid vector pET-M30-MBP and expressed in the Escherichia coli BL21(DE3) expression host. Expression was induced with IPTG and a recombinant peptide was purified using two affinity chromatography steps with Histrap column. The purified peptide was submitted to high-resolution mass spectrometry (HRMS) and structural analyses. Antimicrobial tests were performed using gram-positive (Bacillus thuringiensis) and gram-negative (Burkholderia kururiensis and E. coli) bacteria. Results AgCecropB was expressed in E. coli BL21 (DE3) at 28°C with IPTG 0.5 mM. The recombinant peptide was purified and enriched after purification steps. HRMS confirmed AgCrecropB molecular mass (4.6 kDa) and circular dichroism assay showed α-helix structure in the presence of SDS. AgCrecropB inhibited almost 50% of gram-positive B. thuringiensis bacteria growth. Conclusions The first cecropin B-like peptide was described in A. gemmatalis and a recombinant peptide was expressed using a bacterial platform. Data confirmed tertiary structure as predicted for the cecropin peptide family. AgCecropB was capable to inhibit B. thuringiensis growth in vitro.

Abstract The Program for Biodiversity Research (PPBio) is an innovative program designed to integrate all biodiversity research stakeholders. Operating since 2004, it has installed long-term ecological research sites throughout Brazil and its logic has been applied in some other southern-hemisphere countries. The program supports all aspects of research necessary to understand biodiversity and the processes that affect it. There are presently 161 sampling sites (see some of them at Supplementary Appendix), most of which use a standardized methodology that allows comparisons across biomes and through time. To date, there are about 1200 publications associated with PPBio that cover topics ranging from natural history to genetics and species distributions. Most of the field data and metadata are available through PPBio web sites or DataONE. Metadata is available for researchers that intend to explore the different faces of Brazilian biodiversity spatio-temporal variation, as well as for managers intending to improve conservation strategies. The Program also fostered, directly and indirectly, local technical capacity building, and supported the training of hundreds of undergraduate and graduate students. The main challenge is maintaining the long-term funding necessary to understand biodiversity patterns and processes under pressure from global environmental changes.

ABSTRACT Background Triatoma infestans (Hemiptera: Reduviidae) is a hematophagous insect and the main vector of Trypanosoma cruzi (Kinetoplastida: Trypanosomatidae). In the present study, the authors investigated whether a serine protease activity from the saliva of T. infestans has a role in vasomotor modulation, and in the insect-blood feeding by cleaving and activating protease-activated receptors (PARs). Methods T. infestans saliva was chromatographed as previously reported for purification of triapsin, a serine protease. The cleavage activity of triapsin on PAR peptides was investigated based on FRET technology. Mass spectrometry was used to analyze the sites of PAR-2 peptide cleaved by triapsin. NO measurements were performed using the DAN assay (2,3-diaminonapthalene). The vasorelaxant activity of triapsin was measured in vessels with or without functional endothelium pre-contracted with phenylephrine (3 µM). Intravital microscopy was used to assess the effect of triapsin on mouse skin microcirculation. Results Triapsin was able to induce hydrolysis of PAR peptides and showed a higher preference for cleavage of the PAR-2 peptide. Analysis by mass spectrometry confirmed a single cleavage site, which corresponds to the activation site of the PAR-2 receptor. Triapsin induced dose-dependent NO release in cultured human umbilical vein endothelial cells (HUVECs), reaching a maximum effect at 17.58 nM. Triapsin purified by gel-filtration chromatography (10-16 to 10-9 M) was applied cumulatively to mouse mesenteric artery rings and showed a potent endothelium-dependent vasodilator effect (EC30 = 10-12 M). Nitric oxide seems to be partially responsible for this vasodilator effect because L-NAME (L-NG-nitroarginine methyl ester 300 µM), a nitric oxide synthetase inhibitor, did not abrogate the vasodilation activated by triapsin. Anti-PAR-2 antibody completely inhibited vasodilation observed in the presence of triapsin activity. Triapsin activity also induced an increase in the mouse ear venular diameter. Conclusion Data from this study suggest a plausible association between triapsin activity mediated PAR-2 activation and vasodilation caused by T. infestans saliva.

Abstract Objective: The objective of PHASE-MX registry is to validate the efficacy and safety of the pharmacoinvasive strategy in comparison with percutaneous coronary intervention (PCI) in patients with acute myocardial infarction with ST segment elevation (STEMI) in a metropolitan region of Mexico. The primary outcome will consist of the composite of cardiovascular death, re-infarction, stroke and cardiogenic shock. Methods: The PHASE-MX registry will include a prospective cohort of patients with STEMI who received reperfusion treatment (mechanical of pharmacological) in the first 12 h after the onset of symptoms. The registry is designed to compare the efficacy and safety of primary PCI and pharmacoinvasive strategy. The simple size was calculated in 344 patients divided into two groups, with an estimated loss rate of 10%. Patients included in the PHASE-MX cohort will be followed for up to one year. Conclusion: In Mexico, only 5 out of 10 patients with STEMI have access to reperfusion therapy. Pharmacoinvasive strategy is takes advantage of the accessibility of fibrinolysis and the effectiveness of PCI. The present research protocol aims to provide information that serves as a link between information derived from controlled clinical trials and records derived from real world experience.
Resumen Objetivo: El objetivo del registro PHASE-MX es validar la eficacia y seguridad de la estrategia farmacoinvasiva en comparación con la angioplastia coronaria transluminal percutánea primaria (ACTPp) en pacientes con infarto agudo de miocardio con elevación del segmento ST (IAMCEST) en una región metropolitana de México. El desenlace primario es el compuesto de muerte cardiovascular, reinfarto, accidente vascular cerebral y choque cardiogénico. Métodos: El registro PHASE-MX es una cohorte prospectiva de pacientes con IAMCEST que recibieron tratamiento de reperfusión (mecánico o farmacológico) en las primeras 12 horas desde el inicio de los síntomas, atendidos en el Instituto Nacional de Cardiología Ignacio Chávez. El análisis estadístico se basa en la no inferioridad de la estrategia farmacoinvasiva en comparación con la ACTPp. Se calcula un tamaño de muestra de 344 pacientes divididos en dos grupos (angioplastia primaria y estrategia farmacoinvasiva), considerada una tasa de pérdidas de 10%. Los pacientes incluidos en la cohorte PHASE-MX se seguirán durante un año. Discusión: En México, sólo 5 de cada 10 pacientes con IAMCEST tienen acceso al tratamiento de reperfusión. La estrategia farmacoinvasiva aprovecha la accesibilidad de la fibrinólisis y la efectividad de la ACTPp, por lo que podría resultar el método de elección en el tratamiento del IAMCEST en la mayoría de los casos. El presente protocolo de investigación pretende aportar información que sirva como enlace entre la información derivada de los estudios clínicos controlados y los registros derivados de la experiencia del mundo real.

Resumo Objetivo: Caracterizar o frênulo lingual de recém-nascidos a termo, utilizando dois protocolos diferentes e verificar a relação do frênulo lingual com o aleitamento materno. Método: A amostra não probabilística foi constituída por 449 binômios mãe/bebê. Para a avaliação anatomofuncional do frênulo, utilizou-se o protocolo de avaliação do frênulo lingual para bebês “Teste da Linguinha” e o Bristol Tongue Assessment Tool. A mamada foi avaliada com o protocolo proposto pelo UNICEF. Foram criados escores (bom, regular, ruim) para avaliar cada aspecto da mamada a ser observada. Os resultados foram analisados através de estatísticas descritivas e inferenciais e testes de associação (Qui-quadrado de Pearson e Exato de Fisher). Resultados: O estudo mostrou que 14 bebês apresentaram alteração de frênulo lingual, nos quais três com dificuldade durante a sucção, necessitando de frenotomia na primeira semana de vida e 11 sem dificuldades durante a amamentação. Quanto à avaliação da mamada, 410 binômios mãe/bebê apresentaram o escore bom, 36 regular e 3 ruim. Houve associação estatisticamente significativa entre o protocolo “Teste da Linguinha” e amamentação (p = 0,028) e entre o protocolo Bristol Tongue Assessment Tool e amamentação (p = 0,028). Conclusão: Alterações no frênulo lingual estão associadas a interferências na qualidade da amamentação, sendo importante a avaliação do frênulo lingual em recém-nascidos.
Abstract Objective: To characterize the lingual frenulum of full-term newborns using two different protocols and to assess the association of the lingual frenulum with breastfeeding. Methods: This non-probabilistic sample consisted of 449 mother/baby binomials. For the anatomo-functional evaluation of the frenulum, the Neonatal Tongue Screening Test and the Bristol Tongue Assessment Tool were used for the evaluation of the lingual frenulum. Breastfeeding was evaluated using the protocol proposed by UNICEF. Scores were created (good, fair, poor) to evaluate every aspect of the breastfeeding to be observed. The results were analyzed through descriptive and inferential statistics and association tests (Pearson's chi-squared and Fisher's exact test). Results: The study showed that 14 babies had a lingual frenulum alteration, of whom three had difficulties during suction, requiring frenotomy in the first week of life, whereas 11 had no difficulties during breastfeeding. Regarding the breastfeeding evaluation, 410 mother/baby binomials had good, 36 regular, and three had bad scores. There was a statistically significant association between the tongue-tie test protocol and breastfeeding (p = 0.028) and between the Bristol Tongue Assessment Tool protocol and breastfeeding (p = 0.028). Conclusion: Alterations in the lingual frenulum are associated with interferences in the quality of breastfeeding and thus, evaluation of the lingual frenulum in newborns is important.

ABSTRACT Introduction: The objective of this research was to explore the association between the presence of depressive symptoms and the existence of symptoms suggestive of urinary incontinence in a group of women treated in a public hospital in Peru. Material and Methods: Cross-sectional study was conducted in women with “Seguro Integral de Salud” who attended the gynecology consultation room of Hospital Nacional Daniel Alcides Carrión during November and December of 2018. A sample was calculated with Epidat version 3.1 and the participants were selected by convenience. The main variables of interest were urinary incontinence and depression, both measured by validated measurement instruments: ICIQ-SF and self-assessment scale for Zung depression, respectively. Fisher's exact and Kruskall-Wallis were used to explore the association. A total of 186 women aged between 40 and 60 years were studied. Results: A total of 176 women (94,6%) defined themselves as incontinent and 183 as depression (98,4%). No association was found between the symptoms suggestive of depression with symptoms suggestive of urinary incontinence (p>0,05), but there was an association between the degree of depressive symptoms and the incontinence score (p = 0,0001). Conclusions: A considerable proportion of women suffer from depressive symptoms and urinary incontinence. On the other hand, there seems to be a possible association between urinary incontinence score and the severity of depressive symptoms. More studies are needed to explore this possible association to elucidate the impact that urinary incontinence has on the mood of women in Peru.
RESUMEN Introducción: El objetivo fue explorar la frecuencia y asociación entre la presencia de síntomas depresivos con la existencia de síntomas sugestivos de incontinencia urinaria en un grupo de mujeres atendidas en un hospital público del Perú. Material y Métodos: Estudio transversal realizado en mujeres con Seguro Integral de Salud que acudieron al consultorio de ginecología del hospital público de alta complejidad Hospital Nacional Daniel Alcides Carrión durante noviembre y diciembre del 2018. Se calculó una muestra con Epidat versión 3.1 y se seleccionó a las participantes por conveniencia. Las principales variables de interés fueron incontinencia urinaria y depresión, ambas medidas mediante instrumentos de medición validados: ICIQ-SF y escala de autoevaluación para la depresión de Zung, respectivamente. Para explorar la asociación se usó exacta de Fisher y Kruskall-Wallis. Resultados: Se estudió a 186 mujeres con edades entre 40 y 60 años. Un total de 176 mujeres (94,6 %) se definieron como incontinentes y 183 con depresión (98,4 %). No se encontró asociación entre los síntomas depresivos con los síntomas sugestivos de incontinencia urinaria (p>0,05), pero sí en el grado de síntomas depresivos con el puntaje de incontinencia (p=0,0001). Conclusiones: Una proporción considerable de mujeres padece de síntomas depresivos y de incontinencia urinaria. Por otra para, parece existir una posible asociación entre los puntajes de incontinencia urinaria y la severidad de los síntomas depresivos. Se requieren más estudios que exploren esta posible asociación para dilucidar el impacto potencial que la incontinencia urinaria posee sobre el estado anímico de las mujeres en Perú.

Abstract Background: Colonic vascular lesion secondary to verapamil overdose is mediated by free radicals, forming vascular microtrombos and endotoxin generation, being a difficult diagnosis. Clinical Case: A 27-year-old female is admitted with an acute abdomen of 4 days after an event referred for a suicidal attempt due to an overdose of verapamil, operating surgically where there is a right transmural colon necrosis, performing a right hemicolectomy with terminal ileostomy. Conclusions: Recognize and properly treat an acute abdomen, not always reach an adequate diagnosis, so a thorough history could conclude.
Resumen Antecedentes: La lesión vascular colónica secundaria a la sobredosis de verapamilo, es mediada por radicales libres, formando microtrombos vasculares y generación de endotoxinas, siendo un diagnostico difícil. Caso Clínico: Femenino de 27 años, ingresa con abdomen agudo de 4 días posteriores a un evento remitido de intento suicida por sobredosis de verapamilo, interviniéndose quirúrgicamente donde se halla necrosis colónica transmural derecha, realizando hemicolectomía derecha con ileostomía terminal. Conclusiones: Reconocer y tratar de forma adecuada un abdomen agudo, no siempre se suele llegar a un adecuado diagnostico, por lo cual una minuciosa anamnesis lograría concluirlo.
