ABSTRACT Objective To investigate the relationship between the levels of adipokines and other endocrine biomarkers and patient outcomes in hospitalized patients with COVID-19. Methods In a prospective study that included 213 subjects with COVID-19 admitted to the intensive care unit, we measured the levels of cortisol, C-peptide, glucagon-like peptide-1, insulin, peptide YY, ghrelin, leptin, and resistin.; their contributions to patient clustering, disease severity, and predicting in-hospital mortality were analyzed. Results Cortisol, resistin, leptin, insulin, and ghrelin levels significantly differed between severity groups, as defined by the World Health Organization severity scale. Additionally, lower ghrelin and higher cortisol levels were associated with mortality. Adding biomarkers to the clinical predictors of mortality significantly improved accuracy in determining prognosis. Phenotyping of subjects based on plasma biomarker levels yielded two different phenotypes that were associated with disease severity, but not mortality. Conclusion As a single biomarker, only cortisol was independently associated with mortality; however, metabolic biomarkers could improve mortality prediction when added to clinical parameters. Metabolic biomarker phenotypes were differentially distributed according to COVID-19 severity but were not associated with mortality. COVID19.

RESUMO Objetivo Investigar a relação entre os níveis de adipocinas e outros biomarcadores endócrinos e os desfechos em pacientes hospitalizados com COVID-19. Métodos Estudo prospectivo que incluiu 213 indivíduos com COVID-19 internados na unidade de terapia intensiva, em que foram medidos os níveis de cortisol, peptídeo-C, peptídeo-1 semelhante ao glucagon, insulina, peptídeo YY, grelina, leptina e resistina; analisamos suas contribuições para o agrupamento de pacientes, gravidade da doença e previsão de mortalidade hospitalar. Resultados Os níveis de cortisol, resistina, leptina, insulina e grelina diferiram significativamente entre os grupos por gravidade, conforme definido pela escala de gravidade da Organização Mundial da Saúde. Além disso, níveis mais baixos de grelina e mais altos de cortisol foram associados à mortalidade. A adição de biomarcadores aos preditores clínicos de mortalidade melhorou significativamente a precisão na determinação do prognóstico. A fenotipagem de indivíduos com base nos níveis de biomarcadores plasmáticos produziu dois fenótipos diferentes, que foram associados à gravidade da doença, mas não à mortalidade. Conclusão Como único biomarcador, apenas o cortisol foi independentemente associado à mortalidade; no entanto, os biomarcadores metabólicos podem melhorar a previsão de mortalidade quando associados a parâmetros clínicos. Os fenótipos dos biomarcadores metabólicos foram distribuídos diferencialmente, conforme a gravidade da COVID-19, mas não foram associados à mortalidade. COVID19.

ABSTRACT Objective: To assess factors associated with long-term neuropsychiatric outcomes, including biomarkers measured after discharge from the intensive care unit. Methods: A prospective cohort study was performed with 65 intensive care unit survivors. The cognitive evaluation was performed through the Mini-Mental State Examination, the symptoms of anxiety and depression were evaluated using the Hospital Anxiety and Depression Scale, and posttraumatic stress disorder was evaluated using the Impact of Event Scale-6. Plasma levels of amyloid-beta (1-42) [Aβ (1-42)], Aβ (1-40), interleukin (IL)-10, IL-6, IL-33, IL-4, IL-5, tumor necrosis factor alpha, C-reactive protein, and brain-derived neurotrophic factor were measured at intensive care unit discharge. Results: Of the variables associated with intensive care, only delirium was independently related to the occurrence of long-term cognitive impairment. In addition, higher levels of IL-10 and IL-6 were associated with cognitive dysfunction. Only IL-6 was independently associated with depression. Mechanical ventilation, IL-33 levels, and C-reactive protein levels were independently associated with anxiety. No variables were independently associated with posttraumatic stress disorder. Conclusion: Cognitive dysfunction, as well as symptoms of depression, anxiety, and posttraumatic stress disorder, are present in patients who survive a critical illness, and some of these outcomes are associated with the levels of inflammatory biomarkers measured at discharge from the intensive care unit.

Abstract Effects were assessed of the dilutants TRIS and ACP - 101c® with the addition of different guinea fowl (Numida meleagris) egg yolk concentrations. Fifteen ejaculates were collected from five goats of the Anglo Nubian breed. The ejaculates were pooled and then divided into 12 groups, two control groups (GC1 TRIS, with 2.5% Gallus gallus domesticus hen egg yolk GOGD), (GC2 Control Group ACP - 101c®, with the addition of 2.5% Gallus gallus domesticus hen egg yolk GOGD) and ten experimental groups (EG), containing TRIS and ACP added with different concentrations of egg yolk from guinea hen (Numida meleagris) (TRIS 2,5% GONM; TRIS 5% GONM; TRIS 10% GONM; TRIS 15% GONM; TRIS 20% GONM; ACP® 2,5% GONM; ACP® 5% GONM; ACP® 10% GONM; ACP® 15% GONM; ACP® 20% GONM). Then cryopreservation was carried out and the samples stored in liquid nitrogen (-196 °C). After seven days, the samples were thawed and assessed for spermatic kinetics, immunofluorescence and sperm morphology. Analysis of GOMN by the CASA system showed that the various parameters were similar to those of GOGD (P>0.05). The membrane integrity, mitochondrial potential and the acrosome were not influenced by the treatment (P>0.05) nor by the dilutant used for cryopreservation (P>0.05). The spermatic morphology was also preserved by the different GOGD and GONM concentrations in the ACP® and TRIS dilutants, with no statistically significant differences (P<0.05). It was concluded that Numida meleagris egg yolk, as external membrane cryoproctant added to the dilutants ACP-101c® and TRIS, improved goat semen quality.

RESUMO: O objetivo desta revisão foi abordar a aplicabilidade da nanotecnologia na medicina veterinária, com ênfase nas pesquisas no Brasil de 2013 a 2020. Primeiramente, apresentam-se os aspectos gerais da aplicabilidade da nanotecnologia em medicina veterinária e, posteriormente, apontam-se as pesquisas envolvendo nanociência realizadas no Brasil, no período estudado. A nanotecnologia é o campo da ciência capaz de organizar a matéria em estruturas de nanoescala (1 a 100 nm), permitindo inovações em diferentes áreas, incluindo biotecnologia, agricultura, diagnóstico de doenças, indústria de alimentos e vestuário, eletrônica e terapias farmacológicas. Na medicina veterinária, diversos estudos estão sendo realizados no mundo, principalmente nas áreas que envolvem a busca de novas opções de tratamento e o desenvolvimento de imunoterapia, bem como no diagnóstico de doenças. No Brasil, está claro que o uso da nanotecnologia na medicina veterinária ainda é incipiente, mas pode ser considerada uma área em crescimento. Além disso, vários pontos devem ser refletidos e pesquisados, incluindo alguns efeitos adversos e implicações para validar o uso seguro da nanotecnologia na medicina veterinária. Nesta revisão, destaca-se a nanotecnologia como uma alternativa promissora no atual contexto de inovação tecnológica brasileira, envolvendo saúde animal, o diagnóstico e o potencial uso terapêutico no controle de doenças em medicina veterinária. Em relação às perspectivas futuras, acredita-se que maiores investimentos em ciência e tecnologia são fatores fundamentais a contribuir para o avanço e fortalecimento da nanotecnologia no Brasil.

ABSTRACT: The purpose of this review was to address the applicability of nanotechnology in veterinary medicine, with an emphasis on research in Brazil from 2013 to 2020. Firstly, we introduced to the general aspects of applicability of nanotechnology in veterinary medicine, and lately we pointed the research involving nanoscience performed in Brazil, in the studied period. Nanotechnology is the field of science that has the capacity to organize matter in nanoscale structures (1 to 100 nm), enabling innovations in different areas including biotechnology, agriculture, disease diagnosis, food and clothing industry, electronics, and pharmacological therapies. In veterinary medicine, several studies are being carried out in the world, mainly in the areas that involve search of new treatment options and the development of immunotherapy, as well as in the diagnosis of diseases. In Brazil, it is clear that the use of nanotechnology in veterinary medicine is still incipient, but it can be considered a growing area. In addition, several points have to be reflected and researched, including some adverse effects and implications to validate the safe use of nanotechnology in veterinary medicine. Therefore, this review highlighted the nanotechnology as a promise alternative in the current context of Brazilian technological innovation involving animal health, as well as a possible diagnostic tool and highlighting its potential therapeutic use in disease control in veterinary medicine. Regarding future perspectives, we believed that greater investment in science and technology could contribute to the advancement and strengthening of nanotechnology in Brazil.

Abstract Covid-19 is a novel infectious disease whose spectrum of presentation ranges from absence of symptoms to widespread interstitial pneumonia associated with severe acute respiratory syndrome (SARS), leading to significant mortality. Given the systemic pattern of Covid-19, there are many factors that can influence patient's functional capacity after acute infection and the identification of such factors can contribute to the development of specific rehabilitation strategies. Pulmonary impairment is the primary cause of hospitalization due to Covid-19, and can progress to SARS as well as increase length of hospitalization. Moreover, cardiac involvement is observed in approximately 30% of hospitalized patients, with an increased risk of acute myocarditis, myocardial injury, and heart failure, which may compromise functional capacity in the long-term. Thromboembolic complications have also been reported in some patients with Covid-19 and are associated with a poor prognosis. Musculoskeletal complications may result from long periods of hospitalization and immobility, and can include fatigue, muscle weakness and polyneuropathy. Studies that address the functional capacity of patients after Covid-19 infection are still scarce. However, based on knowledge from the multiple systemic complications associated with Covid-19, it is reasonable to suggest that most patients, especially those who underwent prolonged hospitalization, will need a multiprofessional rehabilitation program. Further studies are needed to evaluate the functional impact and the rehabilitation strategies for patients affected by Covid-19.

Resumo O estudo avaliou a atividade ovicida de extratos enzimáticos de Purpureocillium lilacinum e Trichoderma virens sobre ovos de tricostrongilídeos de ovinos. Extrato filtrado (EF) e extrato macerado bruto (EMB) foram preparados a partir de culturas fúngicas em caldo mínimo. No ensaio experimental, 100 ovos de tricostrongilídeos, obtidos de fezes de ovinos naturalmente infectados, foram expostos durante 24 e 48 horas/25ºC aos extratos dos fungos. No grupo controle, os ovos foram incubados em caldo mínimo. O número de larvas L1 foi determinado. Cada tratamento consistiu em quatro repetições e o experimento foi repetido cinco vezes. Observou-se que o efeito ovicida do EF e EMB de P. lilacinum e T. virens diferiu do grupo controle. O EMB de T. virens e P. lilacinum evidenciou atividade ovicida superior ao EF em ambos os períodos avaliados e em 48 horas de exposição, respectivamente. O percentual de redução de eclodibilidade evidenciou que o EMB foi superior ao EF em ambos os fungos. Este estudo demonstra o potencial ovicida desses fungos sobre ovos de tricostrongilídeos. No entanto, estudos adicionais são necessários para identificar as moléculas responsáveis pelo efeito ovicida, bem como avaliar o comportamento dos extratos fúngicos em interações bióticas e abióticas.

Abstract The study evaluated the ovicidal activity of enzymatic extracts of Purpureocillium lilacinum and Trichoderma virens against trichostrongylid eggs from sheep. Filtered extract (FE) and macerated crude extract (MCE) were prepared from fungal cultures in minimal broth. In the experiment, 100 trichostrongylid eggs, obtained from the feces of naturally infected sheep, were exposed to fungal extracts for 24 and 48 hours/25°C. In the control group, eggs were incubated in minimal broth. The number of L1 larvae was ascertained. Each treatment consisted of four repetitions and the experiment was repeated five times. It was observed that the effect of FE and MCE of P. lilacinum and T. virens on egg hatchability differed from that of the control group. MCE of T. virens and P. lilacinum showed higher ovicidal activity than FE over both periods and at 48 hours of exposure, respectively. From the percentage reductions in hatchability of the eggs, MCE was shown to be superior to FE for both fungi. This study demonstrated the ovicidal potential of these fungi against trichostrongylid eggs. However, further studies are needed in order to identify the molecules responsible for the ovicidal effects, and to evaluate the behavior of fungal extracts in biotic and abiotic interactions.

Resumo Purpureocillium lilacinum é um fungo nematófago com potencial para uso no controle biológico de parasitos, incluindo Toxocara canis. Este estudo pesquisou a infectividade de ovos de T. canis embrionados após exposição ao fungo P. lilacinum . Ovos de T. canis foram expostos ao fungo por 15 ou 30 dias e subsequentemente administrados a camundongos Swiss (n=20). O grupo controle consistiu de camundongos que receberam ovos embrionados do parasita sem exposição ao fungo. Quarenta e oito horas após a infecção, coração, pulmão e fígado dos camundongos foram coletados para avaliar a recuperação larval. Os órgãos dos animais que receberam ovos embrionados expostos ao fungo apresentaram menor média de recuperação larval (P<0,05) do que os infectados com ovos sem exposição ao fungo, sugerindo que a exposição dos ovos de T. canis a P. lilacinum foi capaz de reduzir a infecção experimental. Nas condições avaliadas, o tempo de interação entre o fungo e os ovos do parasito não foi um fator significativo na recuperação das larvas. P. lilacinum pode ser considerado um promissor agente de controle biológico de T. canis, no entanto, mais estudos são necessários para avaliar o emprego deste fungo como um agente de controle biológico.

Abstract Purpureocillium lilacinum is a nematophagous fungus used in biological control against some parasites, including Toxocara canis. This study researched the infectivity of embryonated T. canis eggs after exposure to the fungus P. lilacinum. T. canis eggs were exposed to P. lilacinum for 15 or 30 days and subsequently administered to Swiss mice (n=20). Control group consisted of mice who received T. canis embryonated eggs without fungal exposure. Forty-eight hours after infection, heart, lung, and liver from animals of each group were collected to assess larval recovery. The organs of mice that received embryonated eggs exposed to the fungus showed a lower average larval recovery (P<0.05) suggesting that exposure of T. canis eggs to P. lilacinum was able to reduce experimental infection. Under the evaluated conditions, the interaction time between the fungus and the parasite eggs was not a significant factor in larvae recovery. P. lilacinum may be considered a promising T. canis biological control agent. However, further studies are needed to determine a protocol for the use of this fungus as a biological control agent.

RESUMO: O objetivo deste trabalho foi produzir microcápsulas de pectina, contendo Lactobacillus acidophilus por gelificação iônica externa, seguida da adsorção de proteína de soro de leite e multicamadas formadoras de pectina. Além disso, a viabilidade de lactobacilos livres e microencapsulados, após exposição in vitro a condições gastrintestinais, foi avaliada após simulação de tratamentos térmicos e, finalmente, estabilidade a -18 ºC, 5 ºC e 25 ºC durante 120 dias de armazenamento. A exposição a diferentes pHs, simulando a passagem pelo trato gastrointestinal, mostrou que os tratamentos das microcápsulas com apenas pectina (LA/P0) e com uma e duas camadas proteína do soro (tratamentos LA/P1 e LA/P3, respectivamente), foram capazes de proteger o Lactobacillus acidophilus , enquanto as microcápsulas aumentaram a liberação de probióticos do estômago para o intestino. As células livres diminuíram suas contagens no curso do sistema. Em relação aos tratamentos térmicos aplicados, pode-se afirmar que a microcápsula com uma camada de proteína do soro (LA/P1) resistiu e manteve a viabilidade de Lactobacillus acidophilus (9,57 log CFU / g-1). A melhor viabilidade foi obtida no armazenamento a -18 ° C, com uma contagem de 7,86 log CFU / g-1 para essa mesma microcápsula (LA/P1) no final do armazenamento (120 dias) e 6,55 log CFU / g-1 para as microcápsulas com duas camadas de proteína do soro (LA/P3) por 105 dias. Este estudo indica que a gelificação iônica externa é eficaz e pode ser usada para a produção de microcápsulas de pectina com multicamadas de proteína de soro para promover maior proteção e viabilidade ao Lactobacillus acidophilus.

ABSTRACT: This study produced pectin microcapsules containing Lactobacillus acidophilus by external ionic gelation, followed by the adsorption of whey protein and pectin to form multilayers. The viability of free and microencapsulated lactobacilli was evaluated after in vitro exposure to gastrointestinal conditions. They were also assessed by heat treatment, and stability was examined at -18 °C, 5 °C and 25 °C for 120 days. Exposure to different pHs, simulating passage through the gastrointestinal tract, showed that treatment of the microcapsules with only pectin (LA/P0) and with one and two layers of whey protein (treatments LA/P1 and LA/P3, respectively), were able to protect Lactobacillus acidophilus , with microcapsules increasing the release of probiotics from the stomach into the intestines. Free cells showed a decrease in their counts over the course of the simulated gastrointestinal system. Regarding heat treatments, microcapsules with a layer of whey protein (LA/P1) maintained the viability of their encapsulated Lactobacillus acidophilus (9.57 log CFU/g-1). The best storage viability was at -18 °C, with a count of 7.86 log CFU/g-1at 120 days for microcapsule LA/P1,with those consisting of two layers of whey protein (LA/P3)having a 6.55 log CFU/g-1 at 105 days. This study indicated that external ionic gelation was effective and could be used for the production of pectin microcapsules, with multilayer whey protein promoting greater protection and viability of Lactobacillus acidophilus.

Resumo Este estudo verificou a frequência de oocistos de Cryptosporidium spp. em fezes de cães e gatos em cinco municípios da região sul do Rio Grande do Sul e fatores de risco associados à infecção. Amostras de fezes de 110 cães e 18 gatos foram coradas pelo método de auramina. No momento da coleta de fezes aplicou-se um questionário aos tutores dos animais com questões semiabertas e os dados foram submetidos à análise estatística. A frequência verdadeira de oocistos de Cryptosporidium spp. foi de 24,63% (27 cães e 2 gatos). Apenas quatro amostras de fezes caninas eram diarreicas e todas sem oocistos. As variáveis que representaram fatores de risco para a infecção foram: alimentos de preparo caseiro, água não tratada, circulação dos animais em terreno gramíneo e convivência com outros animais, principalmente bovinos. Os resultados sugerem que a frequência de cães parasitados por Cryptosporidium spp. é relevante, reforçando o caráter assintomático da infeção. Destaca-se a importância da adoção de medidas de controle, particularmente das variáveis que representaram fatores de risco à infecção.

Abstract This study investigated the frequency of oocysts of Cryptosporidium spp. in feces from dogs and cats in five municipalities in the southern region of the state of Rio Grande do Sul. The risk factors associated with infection were also investigated. Feces samples from 110 dogs and 18 cats were stained using the auramine method. At the time of feces sampling, a questionnaire with semi-open-ended questions was applied to the animal guardians and all data obtained underwent statistical analysis. The real frequency of oocysts of Cryptosporidium spp. was 24.63% (27 dogs and two cats). Only four samples of dog feces were diarrheic and no presence of oocysts was observed in any of them. Variables that represented risk factors for infection were: homemade food, untreated water, circulation of animals on grassy terrain and living in the same environment as other animals (cattle). The results made it possible to inferring that within the population studied, the frequency of parasitism due to Cryptosporidium spp. in dogs was relevant and emphasize the asymptomatic nature of this infection. The adopting control measures are highlighted, particularly in relation to variables that represent risk factors for this infection.

Resumo A síndrome de Gitelman (SG) é uma forma rara de nefropatia autossômica recessiva perdedora de sal, caracterizada classicamente por hipocalemia, hipomagnesemia, hipocalciúria, alcalose metabólica e pressão arterial baixa. Fadiga, fraqueza muscular e paralisia muscular estão entre seus sintomas mais comuns. Além dos distúrbios eletrolíticos típicos, outros achados laboratoriais incluem a hiperreninemia e o hiperaldosterismo secundário. Nefrocalcinose bilateral pode ocorrer. O tratamento consiste basicamente na reposição de potássio e uso de antagonistas da aldosterona. A melhor abordagem para gestantes portadoras de SG ainda está por ser definida. Entretanto, enfatiza-se a necessidade de suplementação dos íons, o controle do peso como ferramenta clínica de avaliação do balanço hídrico e a monitorização frequente do feto e dos níveis de líquido amniótico. O risco cirúrgico associado à cesariana em paciente com SG não está definido. Apesar dos riscos associados às crises sintomáticas de hipocalemia/hipomagnesemia, a SG apresenta bom prognóstico quando adequadamente tratada. A gravidez impõe a necessidade de controle mais intenso da doença, mas apresenta bom prognóstico para o binômio materno-fetal.

Abstract Gitelman's Syndrome (GS) is a rare autosomal recessive salt-wasting nephropathy, classically characterized by hypokalemia, hypomagnesemia, hypocalciuria, metabolic alkalosis and low blood pressure. Fatigue, muscle weakness and muscle paralysis are common symptoms. Besides the typical electrolyte disturbances, others laboratory findings include hyperreninemia and secondary hyperaldosteronism. Bilateral nephrocalcinosis may occur. The treatment consists of potassium replacement and use of aldosterone antagonists. The best approach to pregnant women with GS is yet to be defined. However, we emphasize the need for ions supplementation, weight control as a clinical tool for assessing the water balance, and frequent monitoring of the fetus and amniotic fluid levels. The surgical risk associated with cesarean section in a patient with GS is not yet defined. Despite the risks related to symptomatic episodes of hypokalemia/hypomagnesemia, GS has a good prognosis when treated properly. Pregnancy imposes the need for more intensive control of the disease, but has a good prognosis for the mother and neonate.

OBJECTIVE: To investigate the pathogenesis of bloodstream infection by Staphylococcus epidermidis, using the molecular epidemiology, in high-risk neonates. METHODS: We conducted a prospective study of a cohort of neonates with bloodstream infection using central venous catheters for more than 24 h. "National Healthcare Safety Network" surveillance was conducted. Genotyping was performed by DNA fingerprinting and mecA genes and icaAD were detected by multiplex-PCR. RESULTS: From April 2006 to April 2008, the incidence of bloodstream infection and central venous catheter-associated bloodstream infection was 15.1 and 13.0/1000 catheter days, respectively, with S. epidermidis accounting for 42.9% of episodes. Molecular analysis was used to document the similarity among six isolates of bloodstream infection by S. epidermidis from cases with positive blood and central venous catheter tip cultures. Fifty percent of neonates had bloodstream infection not identified as definite or probable central venous catheter-related bloodstream infection. Only one case was considered as definite central venous catheter-related bloodstream infection and was extraluminally acquired; the remaining were considered probable central venous catheter-related bloodstream infections, with one probable extraluminally and another probable intraluminally acquired bloodstream infection. Additionally, among mecA+ and icaAD+ samples, one clone (A) was predominant (80%). A polyclonal profile was found among sensitive samples that were not carriers of the icaAD gene. CONCLUSIONS: The majority of infections caused by S. epidermidis in neonates had an unknown origin, although 33.3% appeared to have been acquired intraluminally and extraluminally. We observed a polyclonal profile between sensitive samples and a prevalent clone (A) between resistant samples.

Introduction Nine cases of visceral leishmaniasis occurred recently in Barra Mansa, State of Rio de Janeiro, with a high mortality rate. Methods We reviewed the medical records of the patients. Results Eight were male; 7 were adults. Patients who died progressed to death quickly and presented with aggravating factors: systemic steroid therapy before diagnosis, bleeding, severe liver involvement, infection, and/or refusal to receive transfusion. Conclusions We warn clinicians to be aware of the emergence of visceral leishmaniasis in new areas and to keep in mind the possibility of atypical clinical pictures and aggravating factors, so timely diagnosis can be made and prompt and adequate treatment can be initiated.
