ABSTRACT: Leptospirosis, a disease of significant economic impact on livestock and public health concern, may exhibit unique epidemiological characteristics in indigenous villages, particularly those located within semiarid climates such as the Caatinga biome in Brazil. This environment often presents conditions unfavorable for leptospire survival. This study conducted serological diagnoses of livestock in indigenous villages within the Caatinga biome, Northeastern Brazil. The survey was carried out in the Mãe Maria and Santa Helena indigenous villages, home to the Xukuru de Cimbres tribe, in the county of Pesqueira, Pernambuco State, Brazil, within the Caatinga biome. Blood samples were collected from cattle (n = 42), goats (n = 41), and sheep (n = 19). Out of the 102 samples tested, 73 (71.6%; 95% CI = 62.8% - 80.3%) were seroreactive (cut-off ≥ 100). The seropositivity rates for cattle, goats, and sheep were 54.8%, 80.5%, and 89.5%, respectively. A statistically significant difference was observed in the proportion of seropositive animals between cattle and goats and cattle and sheep (P < 0.05). Icterohaemorrhagiae was identified as the most probable serogroup across all animal species. The study revealed that livestock in indigenous villages within the Caatinga biome are frequently exposed to leptospires. This finding underscores the importance of a One Health approach, emphasizing the need for comprehensive studies in areas where large human and animal populations coexist. Such studies are crucial for investigating zoonotic infections and for planning and implementing control measures against livestock-associated leptospirosis.

RESUMO: A leptospirose causa perdas econômicas na pecuária e é um problema de saúde pública, sendo possível que existam peculiaridades na epidemiologia dessa doença em aldeias indígenas, principalmente naquelas de áreas de clima semiárido, como o bioma Caatinga no Nordeste do Brasil, onde o ambiente é frequentemente adverso à sobrevivência de leptospiras. Assim, o objetivo deste estudo foi realizar o diagnóstico sorológico em rebanhos de aldeias indígenas no bioma Caatinga. A pesquisa foi realizada nas aldeias indígenas Mãe Maria e Santa Helena, tribo Xukuru de Cimbres, município de Pesqueira, estado de Pernambuco, Brasil, dentro do bioma Caatinga. Amostras de sangue foram colhidas de bovinos (n = 42), caprinos (n = 41) e ovinos (n = 19). No geral, das 102 amostras testadas 73 (71,6%; IC 95% = 62,8% - 80,3%) foram sororreativas (ponto de corte ≥ 100). Para bovinos, caprinos e ovinos as taxas de soropositividade foram de 54,8%, 80,5% e 89,5%, respectivamente. Houve diferença estatística na proporção de animais soropositivos entre bovinos e caprinos e bovinos e ovinos (P < 0,05). Icterohaemorrhagiae foi o sorogrupo mais provável em todas as espécies animais. O estudo mostra que animais de produção de aldeias indígenas são comumente expostos a leptospiras no bioma Caatinga, o que constitui uma preocupação do ponto de vista de Saúde Única e demonstra a importância de estudos amplos em que coexistem grandes números de humanos e animais na investigação de infecções zoonóticas e no planejamento e implementação de medidas de controle da leptospirose associada a animais de produção.

Abstract Background Evidence indicates a strong link between Zika virus (ZikV) and neurological complications. Acute myelitis, optic neuritis, polyneuropathy, and encephalomyelitis that mimic inflammatory idiopathic demyelination disorders (HDD) after ZikV infection have been reported in Brazil. Objective The present study aims to investigate the possible occurrence of molecular mimicry between ZikV antigens and Multiple Sclerosis (MS) autoantigens, the most frequent HDD of the central nervous system (CNS). Methods A retrospective cohort study with 305 patients admitted due to suspected arbovirus infection in Rio de Janeiro was performed, all subjects were submitted to neurological examination, and a biological sample was collected for serologic and molecular diagnostic. Bioinformatics tools were used to analyze the peptides shared between ZikV antigens and MS autoantigens. Results Of 305 patients, twenty-six were positive for ZikV and 4 presented IDD patterns found in MS cases. Sequence homology comparisons by bioinformatics approach between NS5 ZikV and PLP MS protein revealed a homology of 5/6 consecutive amino acids (CSSVPV/CSAVPV) with 83% identity, deducing a molecular mimicry. Analysis of the 3D structures revealed a similar conformation with alpha helix presentation. Conclusions Molecular mimicry between NS5 Zika virus antigen and PLP MS autoantigens emerge as a possible mechanism for IDD spectrum in genetically susceptible individuals.

Resumo Antecedentes Evidências indicam uma forte ligação entre o vírus Zika (ZikV) e complicações neurológicas. Mielite aguda, neurite óptica, polineuropatia e encefalomielite que mimetizam distúrbios inflamatórios de desmielinização idiopáticos (DDII) após infecção por ZikV têm sido relatadas no Brasil. Obejtivo O presente estudo tem como objetivo investigar a possível ocorrência de mimetismo molecular entre antígenos do ZikV e autoantígenos da Esclerose Múltipla (EM), a DDII mais frequente do sistema nervoso central (SNC). Métodos Foi realizado um estudo de coorte retrospectivo com 305 pacientes internados por suspeita de infecção por arbovirus no Rio de Janeiro, todos os indivíduos foram submetidos a exame neurológico e coleta de amostra biológica para diagnóstico sorológico e molecular. Ferramentas de bioinformática foram usadas para analisar os peptídeos compartilhados entre antígenos do ZikV e autoantígenos da EM. Resultados Dos 305 pacientes, vinte e seis foram positivos para ZikV e 4 apresentaram padrão IDD encontrado em casos de EM. As comparações de homologia de sequência por abordagem de bioinformática entre a proteína NS5 ZikV e PLP EM revelaram uma homologia de 5/6 aminoácidos consecutivos (CSSVPV/CSAVPV) com 83% de identidade, deduzindo um mimetismo molecular. A análise das estruturas 3D revelou uma conformação semelhante com apresentação em alfa-hélice. Conclusões O mimetismo molecular entre o antígeno NS5 do vírus Zika e o autoantígeno PLP da EM surge como um possível mecanismo para o espectro IDD em indivíduos geneticamente suscetíveis.

ABSTRACT Timely and accurate diagnosis is one of the strategies for managing visceral leishmaniasis (VL). Given the specificities of this infection, which affects different vulnerable populations, the local assessment of the accuracy of the available diagnostic test is a requirement for the good use of resources. In Brazil, performance data are required for test registration with the National Regulatory Agency (ANVISA), but there are no minimum requirements established for performance evaluation. Here, we compared the accuracy reported in the manufacturer’s instructions of commercially available VL-diagnostic tests in Brazil, and the accuracies reported in the scientific literature which were obtained after test commercialization. The tests were identified via the electronic database of ANVISA, and their accuracy was obtained from the manufacturer’s instructions. A literature search for test accuracy was performed using two databases. A total of 28 VL diagnostic tests were identified through the ANVISA database. However, only 13 presented performance data in the manufacturer’s instructions, with five immunoenzymatic tests, three indirect immunofluorescence tests, one chemiluminescence test, and four rapid tests. For most tests, the manufacturers did not provide the relevant information, such as sample size, reference standards, and study site. The literature review identified accuracy data for only 61.5% of diagnostic tests registered in Brazil. These observations confirmed that there are significant flaws in the process of registering health technologies and highlighted one of the reasons for the insufficient control of policies, namely, the use of potentially inaccurate and inappropriate diagnostic tools for a given scenario.

ABSTRACT This work aims at evaluating and discriminating crambe genotypes regarding tolerance to water deficit by means of morpho-agronomic and physiological traits. The trial was carried out in a greenhouse under a randomized complete block design with four blocks, in a 2 x 8 factorial scheme, being two environments (with and without stress) and eight genotypes (FMS CR 1101, FMS CR 1106, FMS CR 1203, FMS CR 1305, FMS CR 1307, FMS CR 1312 and FMS CR 1326 and cultivar FMS Brilhante). The genotypes were evaluated according to physiological and morpho-agronomic traits. The significance of the mean squares was tested by the F test (P < 0.05) and the genetic parameters were estimated as ratio b between the genetic (CVg) and experimental (CVe) coefficients of variation, broad-sense heritability at genotypic mean level ( h ^ m 2), intraclass correlation (r) and selective accuracy (Ac). In general, water deficit did not cause severe physiological limitations to the plants. Plant height (PH), total dry mass (TDM) and grain yield (GY) were the traits that stood out for presenting the highest estimates of ratio b, h ^ m 2), CVg and r, revealing the possibility of genetic gains with the selection. Nevertheless, after evaluating the performance of genotypes in terms of physiological and morpho-agronomic traits, it was concluded that cultivar FMS Brilhante and inbred lines FMS CR 1326 and FMS CR 1106 had the most favorable traits for the selection, therefore, presenting potential for water deficit tolerance.

Abstract Objectives: to analyze the consumption of ultra-processed food and its association with body image, physical activity, nutritional status and self-assessment on food of pregnant women enrolled in the Primary Health Care. Methods: this is a cross-sectional study carried out with pregnant women enrolled in the Family Health Strategy in the city of Montes Claros, Minas Gerais. Data were collected through a questionnaire. The dependent variable was the consumption of ultra-processed food, and the independent ones addressed body appearance, physical activity, nutritional status, self-assessment on food and food consumption. Descriptive analysis was carried out and for association of analysis, the linear regression model was used with crude and adjusted associations. Results: 1,185 pregnant women participated in the study. Caloric intake from ultra-processed food represented 32.0% of these women’s daily diet. There was an association between consumption of ultra-processed food and physical activity (β=-0.08; p<0.01), pre-gestional nutritional status (β=-0,12; p<0.01) and body image (β =0.08; p=0.01). Conclusion: the pregnant women presented high consumption of ultra-processed food. Having a negative body image, the lowest level of physical activity, and high pre-gestational nutritional status are conditions that influenced the consumption of these food.

Ter imagem corporal negativa, menor nível de atividade física, estado nutricional pré-gestacional elevado são condições que influenciaram o consumo desses alimentos.

Abstract: Introduction: Although the internet provides various facilities, its inadequate and excessive use can cause Internet Addiction Disorder, especially among university students, who browse the web for entertainment, communication and academic activities, and even more so during the COVID-19 pandemic, when education switched to online. This disorder results in several detrimental consequences such as diminished student performance and aggravation or triggering of other psychiatric conditions. Objective: To evaluate the presence of Internet Addiction Disorder in medical students at the state of Alagoas, Brazil. Methods: Quantitative, cross-sectional and analytic study conducted among medical students from two universities in the state of Alagoas during the first year of the COVID-19 pandemic. The data was gathered through an online form with a social-demographic questionnaire, the Internet Addiction Test, and variables (sex, age, semester of study, city of birth, grade point average). The data was analysed in the SPSS 24 and JASP 0.14 programs. Results: The survey was applied to 325 students, 97.2% of whom affirmed to have increased their internet usage during the pandemic. The average score in the Internet Addiction Test was 32.5, with 80.6% displaying some degree of disorder, 66.8% a mild dependence, and 13.8% moderate dependence. A higher prevalence of the disorder was found among males, who were also shown to be more used to making new friendships through the internet, to hide what they are doing online, and to spend more time logged in than planned. The compulsion was more severe in lower social classes, initial semester and those who came from public university, cities with a population of less than 50.000, and immigrants. There was a negative correlation between lower final semester grades and higher grades in the Internet Addiction Test (Pearson -0,121, p-value: 0,045). Conclusions: The data of this study point to a major possibility of medical students developing Internet Addiction Disorder, with more severe dependence among those who are males, from lower social classes, in earlier periods of study, students from public universities, from cities with a population of less than 50.000 inhabitants and immigrants. The presence of Internet Addiction Disorder was inversely proportional to academic performance.

Resumo: Introdução: Apesar das facilidades proporcionadas pela internet, seu uso inadequado e excessivo pode gerar Transtorno de Uso de Internet, principalmente entre os universitários que a utilizam para entretenimento, comunicação e atividades acadêmicas, como ocorreu durante a pandemia de Covid-19, quando o ensino ficou on-line. Esse transtorno culmina em prejuízos, como a redução no desempenho estudantil e a exacerbação ou o aparecimento de doenças psiquiátricas. Objetivo: Este estudo teve como objetivo avaliar a presença do transtorno de uso de internet entre estudantes de Medicina em universidades do estado de Alagoas, Brasil. Método: Trata-se de um estudo quantitativo, transversal e analítico realizado com estudantes de Medicina de duas instituições de ensino superior do estado de Alagoas durante o primeiro ano de pandemia de Covid-19. A coleta foi feita por um instrumento on-line com uma avaliação sociodemográfica, o Teste de Dependência de Internet e as variáveis sexo, idade, período, cidade de origem e coeficiente acadêmico de rendimento. Os dados foram analisados nos programas SPSS 24 e JASP 0.14. Resultado: Participaram da pesquisa 325 estudantes, dos quais 97,2% afirmaram ter aumentado o consumo da internet durante o período da pandemia. A média de pontuação no teste foi de 32,5, no qual 80,6% apresentaram algum grau de transtorno de uso de internet, sendo 66,8% leve e 13,8% moderado. Constatou-se maior prevalência da dependência no sexo masculino, com achado entre eles de criar novas amizades pela internet, de ocultar revelar o que faz on-line e gastar mais tempo que o planejado navegando. Houve maior gravidade de compulsão nos estudantes de classes sociais mais baixas, em períodos iniciais do curso, provenientes de instituição pública, oriundos de cidades com até 50 mil habitantes e nos imigrantes. Houve uma relação negativa significativa entre menor coeficiente do último período cursado e maior nota no teste (Pearson -0,121, valor de p: 0,045). Conclusão: Os dados apontaram que os estudantes de Medicina estão propensos a desenvolver transtorno de uso de internet e que houve maior gravidade entre o sexo masculino, em classes sociais mais baixas, nos períodos iniciais do curso, nos procedentes de instituição pública, de cidades com até 50 mil habitantes e nos imigrantes. A presença do transtorno foi inversamente proporcional à performance acadêmica.

SUMMARY OBJECTIVE: This study aimed to evaluate the quality of life of patients with endometriosis before and after surgical treatment. METHODS: An observational, longitudinal, and prospective study was conducted with 102 women with pelvic pain and endometriosis that was unimproved by clinical treatment and indicated for surgical treatment. The patients’ quality of life was assessed using the 30-item Endometriosis Health Profile (EHP-30) questionnaire before and 3 and 6 months after surgery. The statistical tests were analyzed using the Statistical Package for Social Sciences version 17.0, and the Friedman test was used. RESULTS: There was a reduction in EHP-30 scores 3 and 6 months after surgery compared to before surgery, as well as 6 months after surgery compared to 3 months after surgery, in the central questionnaire (PART 1) and in Sections A, B, C, E, and F (p<0.0001). For Section D, there was a reduction in scores 6 months after surgery compared to before surgery (p<0.0001). CONCLUSION: Surgical treatment of endometriosis improves quality of life in several areas assessed by the EHP-30 questionnaire.

Abstract Background Data on post-acute COVID-19 in autoimmune rheumatic diseases (ARD) are scarce, focusing on a single disease, with variable definitions of this condition and time of vaccination. The aim of this study was to evaluate the frequency and pattern of post-acute COVID-19 in vaccinated patients with ARD using established diagnosis criteria. Methods Retrospective evaluation of a prospective cohort of 108 ARD patients and 32 non-ARD controls, diagnosed with SARS-CoV-2 infection (RT-PCR/antigen test) after the third dose of the CoronaVac vaccine. Post-acute COVID-19 (≥ 4 weeks and > 12 weeks of SARS-CoV-2 symptoms) were registered according to the established international criteria. Results ARD patients and non-ARD controls, balanced for age and sex, had high and comparable frequencies of ≥ 4 weeks post-acute COVID-19 (58.3% vs. 53.1%, p = 0.6854) and > 12 weeks post-acute COVID-19 (39.8% vs. 46.9%, p = 0.5419). Regarding ≥ 4 weeks post-acute COVID-19, frequencies of ≥ 3 symptoms were similar in ARD and non-ARD controls (54% vs. 41.2%, p = 0.7886), and this was also similar in > 12 weeks post-acute COVID-19 (68.3% vs. 88.2%, p = 0.1322). Further analysis of the risk factors for ≥ 4 weeks post-acute COVID-19 in ARD patients revealed that age, sex, clinical severity of COVID-19, reinfection, and autoimmune diseases were not associated with this condition (p > 0.05). The clinical manifestations of post-acute COVID-19 were similar in both groups (p > 0.05), with fatigue and memory loss being the most frequent manifestations. Conclusion We provide novel data demonstrating that immune/inflammatory ARD disturbances after third dose vaccination do not seem to be a major determinant of post-acute COVID-19 since its pattern is very similar to that of the general population.

Abstract Objectives: to analyze the temporal trend and spatial distribution of infant mortality in Pernambuco from 2001 to 2019. Methods: an ecological study involving all deaths in children under one year of age living in the state. Data were collected from the Mortality Information System and the Live Birth Information System. Four mortality rates were calculated and the temporal analysis was performed by applying the regression model by inflection points of the rates at different spatial levels. Results: 47,949 deaths were recorded, of which 51.0% (n=24,447) occurred in the first six days of life. A statistically significant downward trend was observed in all the rates analyzed (-4.5%/year in overall mortality, -3.6%/year in early neonatal mortality, -1.9%/year in the late neonatal component, and -6.3%/year in the post-neonatal component). Additionally, 64.3% of the municipalities (n=119) showed a declining trend in the overall infant mortality rate. Less than 50% of the municipalities showed a downward trend in early neonatal and late neonatal mortality (41.08%; n=76 and 43.2%; n=80, respectively). In post-neonatal mortality, 57.3% (n=106) showed decreasing trends. Conclusions: there was a temporal trend of decline in overall infant mortality, although there is an important portion of municipalities with a stationary trend, justifying the need to reduce social inequalities and geographical asymmetries.

Resumo Objetivos: analisar a tendência temporal e a distribuição espacial da mortalidade infantil em Pernambuco no período de 2001 a 2019. Métodos: estudo ecológico envolvendo todos os óbitos em crianças menores de um ano residentes no estado. Os dados foram coletados no Sistema de Informações sobre Mortalidade e no Sistema de Informação sobre Nascidos Vivos. Foram calculados quatro coeficientes de mortalidade e a análise temporal foi realizada aplicando o modelo de regressão por pontos de inflexão dos coeficientes em diferentes níveis espaciais. Resultados: foram registrados 47.949 óbitos, dos quais 51,0% (n=24.447) ocorreram nos seis primeiros dias de vida. Foi observada tendência de declínio estatisticamente significativo em todos os coeficientes analisados (-4,5%/ano na mortalidade geral, -3,6%/ano na neonatal precoce, -1,9%/ano no componente neonatal tardio e de -6,3%/ano no componente pós-neonatal). Adicionalmente, 64,3% dos municípios (n=119) apresentaram tendência de declínio no coeficiente de mortalidade infantil geral. Menos de 50% dos municípios apresentaram tendência de redução na mortalidade neonatal precoce e neonatal tardia (41,08%; n=76 e 43,2%; n=80, respectivamente). Na mortalidade pós-neonatal, 57,3% (n=106) apresentaram tendências decrescentes. Conclusões: houve tendência temporal de declínio da mortalidade infantil geral, embora haja importante parcela de municípios com tendência estacionária, justificando a necessidade de reduzir desigualdades sociais e assimetrias geográficas.

RESUMO Objetivo: Investigar a relação entre dispositivos de ventilação não invasiva e incidência de lesão do septo nasal em recém-nascidos pré-termo. Métodos: Este estudo de coorte retrospectivo e unicêntrico incluiu prematuros em uso de ventilação não invasiva. A incidência de lesão nasal foi comparada entre três grupos, de acordo com o dispositivo de ventilação não invasiva (G1 para máscara nasal; G2 para prongas binasais e G3 para alternância entre máscaras e prongas nasais). As lesões nasais foram classificadas de acordo com o National Pressure Ulcer Advisory Panel como estágios 1 - 4. Foram realizadas análises de regressão multivariada para estimar os riscos relativos, a fim de identificar possíveis preditores associados a lesões relacionadas a dispositivos médicos. Resultados: Entre os 300 lactentes incluídos no estudo, a incidência de lesões relacionadas a dispositivos médicos no grupo em uso alternado foi significativamente menor do que a nos grupos de máscara ou prongas de uso contínuo (n = 68; 40,48%; valor de p < 0,01). O grupo de prongas nasais apresentou mais lesões de estágio 2 (n = 15; 55,56%; p < 0,01). A permanência ≥ 7 dias em ventilação não invasiva foi associada a maior incidência de lesões relacionadas a dispositivos médicos, independentemente do dispositivo (63,81%; p < 0,01). Os incrementos diários na ventilação não invasiva aumentaram o risco de lesões nasais em 4% (IC95% 1,02 - 1,06; p < 0,01). Um maior peso ao nascer indicou proteção contra lesões relacionadas a dispositivos médicos. Cada grama extra representou diminuição de 1% no risco de desenvolver lesão do septo nasal (RR: 0,99; IC95% 0,99 - 0,99; p < 0,04). Conclusão: A alternância entre máscaras e prongas nasais reduz a incidência de lesão nasal moderada a grave em comparação com dispositivos únicos. O incremento de dias em uso de ventilação não invasiva parece contribuir para lesões relacionadas a dispositivos médicos, e um maior peso ao nascer é um fator de proteção.

ABSTRACT Objective: To investigate the association between noninvasive ventilation delivery devices and the incidence of nasal septum injury in preterm infants. Methods: This retrospective singlecenter cohort study included preterm infants supported by noninvasive ventilation. The incidence of nasal injury was compared among three groups according to the noninvasive ventilation delivery device (G1 - nasal mask; G2 - binasal prongs; and G3, rotation of nasal mask with prongs). Nasal injury was classified according to the National Pressure Ulcer Advisory Panel as stages 1 - 4. Multivariate regression analyses were performed to estimate relative risks to identify possible predictors associated with medical device-related injuries. Results: Among the 300 infants included in the study, the incidence of medical device-related injuries in the rotating group was significantly lower than that in the continuous mask or prong groups (n = 68; 40.48%; p value < 0.01). The basal prong group presented more stage 2 injuries (n = 15; 55.56%; p < 0.01). Staying ≥ 7 days in noninvasive ventilation was associated with a higher frequency of medical device-related injuries, regardless of device (63.81%; p < 0.01). Daily increments in noninvasive ventilation increased the risk for nasal injury by 4% (95%CI 1.02 - 1.06; p < 0.01). Higher birth weight indicated protection against medical device-related injuries. Each gained gram represented a decrease of 1% in the risk of developing nasal septum injury (RR: 0.99; 95%CI 0.99 - 0.99; p < 0.04). Conclusion: Rotating nasal masks with nasal prongs reduces the incidence of moderate to severe nasal injury in comparison with single devices. The addition of days using noninvasive ventilation seems to contribute to medical device-related injuries, and higher birth weight is a protective factor.

RESUMO: A co-digestão dos dejetos suínos associados a resíduos vegetais é uma alternativa que pode elevar as produções de biogás e metano alcançadas pela digestão isolada do dejeto. No entanto, recomendações que se baseiem na melhor proporção entre dejeto e forragem, assim como na idade de colheita ainda são escassas na literatura. O objetivo do trabalho foi avaliar inclusões crescentes (0, 25, 50, 75 e 100% dos sólidos totais (ST) de capim elefante (Pennisetum purpureum Schum.) colhido em duas idades de corte mediana (MA) aos 45 dias de crescimento e avançada (AA) aos 90 dias, empregado em co-digestão com o dejeto suíno, adotando-se delineamento inteiramente ao acaso, em esquema fatorial 5x2. Foram utilizados biodigestores batelada de bancada, sendo as produções de biogás acompanhadas durante 12 semanas. Houve influência da idade da forragem (P<0,05) na degradação de sólidos e fibra em detergente neutro, com maiores valores para os substratos que continham a forragem MA. Os maiores rendimentos de CH4 foram alcançados pelos substratos que continham forragem MA na inclusão de 27,7 e 31,6 %, sendo de 253,7 e 222,2 L de CH4 por Kg de ST ou sólido volátil adicionado. A idade das forragens influenciou o início e a persistência das produções de biogás ao longo do período de digestão, sendo vantajosa apenas na inclusão de 25% de forragem com MA.

ABSTRACT: The co-digestion of swine manure with vegetable waste is an alternative that can increase the production of biogas and methane generated by the isolated digestion of manure. However, recommendations that are based on the best ratio between manure and forage, as well as the age of harvest, are still scarce in the literature. This study was conducted to evaluate inclusions (0, 25, 50, 75 and 100%) of the total solids (TS) of Elephant grass (Pennisetum purpureum Schum) harvested at two ages medium age (MA) at 45 days of growth and advanced age (AA) at 90 days in co-digestion with swine manure, using an entirely randomized design in a 5x2 factorial scheme. Batch digesters were used and biogas production was monitored for 12 weeks. There was influence of forage age (P <0.05) on the degradation of solids and neutral detergent fiber, with higher values for the substrates containing MA forage. The highest CH4 yields were obtained by the substrates containing MA forage in the inclusion of 27.7 and 31.6%, being 253.7 and 222.2 L of CH4 per Kg of total or volatile solids. The age of the forages influenced the onset and persistence of biogas production, being advantageous only in the inclusion of 25% of MA forage. The AA forage inclusion is not recommended for co-digestion with swine manure.

Abstract: The FACE-Q SFAOS is an instrument developed for esthetic facial procedures and has been validated in patients undergoing rhinoplasty. It consists of ten items that assess the current perception of facial appearance regarding symmetry, harmony, proportion, freshness or vitality, and self-perception of appearance; these items are perhaps important to guide demands in orofacial harmonization (OFH). We aimed to validate the FACE-Q SFAOS scale among professionals working with OFH and verify its acceptance for use in clinical practice. Altogether, 25 OFH specialists were included to evaluate the FACE-Q SFAOS scale and the new technology acceptability model (TAM). Internal validity was measured using Cronbach's α coefficient. Both scales were associated with clinical experience and perceived usefulness using Spearman's correlation and Fisher's exact or chi-square tests (SPSS 20.0, p < 0.05). The FACE-Q SFAOS (α = 0.927) and TAM (α = 0.941) scales demonstrated good internal validity, and most professionals demonstrated good acceptance (TAM >70 = 64%). The mean FACE-Q SFAOS and TAM scores were 64.00±17.03 and 74.60±20.66, respectively. Practitioners with more than two years of experience (p=0.032) who believed the scale was useful for lip filler evaluation (p = 0.017) demonstrated greater acceptance. The number of indications on the scale was directly correlated with higher levels of acceptance (p = 0.002, r = 0.594). Thus, the FACE-Q SFAOS scale has good reproducibility and acceptance among OFH specialists; however, acceptability was shown to be dependent on perceived usability.

Abstract Chronic Lymphocytic Leukemia (CLL) has shown great biological heterogeneity, with a variable prognosis, and a short survival in some patients. In this light, the present study focused on the prognostic utility of circulating microparticles (MPs) and a Thrombin Generation (TG) Profile for thrombotic risk and disease progression in CLL patients. Circulating microparticles and TG were evaluated in 35 patients with CLL and 35 healthy individuals. For circulating microparticles, significant differences were observed among the following groups: MPs derived from endothelial cells (p = 0.002), B lymphocytes (p < 0.001), platelets (p = 0.003), and Tissue Factor MPs in monocytes (p < 0.001). In all cases, MP values were higher for the CLL group. When compared to the controls, CLL patients presented a decrease in TG, characterized by a reduced endogen thrombin potential (ETP) (p = 0.031). When the results were analyzed according to the Binet stage, as compared to the controls, the Binet B+C group also presented lower ETP values (p = 0.009). No significant differences were observed between the control and the Binet A groups or between the Binet A and the Binet B + C groups. Although hemostatic alterations may occur in patients with CLL, these parameters do not seem to be useful to indicate disease progression.

RESUMO: O Brasil é um grande país e com elevada biodiversidade em suas diferentes regiões. Entretanto, espécies de frutas nativas amplamente encontradas no sul do Brasil ainda não foram devidamente exploradas, permanecendo desconhecidas e subutilizadas pela indústria de alimentos. Nesse sentido, o objetivo deste estudo foi avaliar o perfil fenólico, bem como a composição de ácidos orgânicos e de açúcares de polpas de feijoa (Acca sellowiana) e de uvaia (Eugenia pyriformis) provenientes do planalto sul brasileiro. A polpa de uvaia apresentou o maior teor de polifenóis totais e a maior capacidade antioxidante pelos métodos utilizados. A (+)-catequina (6.54 mg 100g-1) foi o principal composto fenólico da polpa da uvaia, o que ainda não foi relatado na literatura para frutas de outras regiões. Além disso, a polpa da feijoa se destacou pela presença de (-)-epicatequina (18.29 mg 100g-1). Dentre os ácidos orgânicos avaliados, as polpas de frutas nativas apresentaram valores para os ácidos cítrico e málico, sendo o ácido málico (553.00 mg 100g-1) o principal na polpa de uvaia, e o cítrico (455.60 mg 100g-1) na polpa de feijoa. Em relação aos açúcares, a polpa da feijoa apresentou o maior teor de açúcar total (11.14 g 100g-1) e foi a única polpa que continha sacarose. Já a polpa da uvaia apresentou a frutose (3.10 g 100g-1) como principal açúcar. Os resultados obtidos neste estudo contribuem para a valorização e conservação das espécies investigadas, representando uma alternativa promissora para a utilização dessas frutas nativas no desenvolvimento de novos produtos.

ABSTRACT: Brazil is a large country with high biodiversity in its different regions. However, species of native fruits widely reported in the southern Brazil have not been properly explored so far, remaining underutilized by the food industry. This study evaluated the polyphenolic profile, as well as the composition of organic acids and sugars of the pulps of the feijoa, and the uvaia from southern brazilian highlands. The uvaia pulp showed the highest total polyphenol content and the highest antioxidant capacity by the methods used. The polyphenol (+)-catechin (6.54 mg 100g-1) was the major phenolic compound in uvaia pulp, which has not yet been reported in the literature for fruits of other regions. In addition, the feijoa pulp stood out for the presence of (-)-epicatechin (18.29 mg 100g-1). The pulps of native fruits in this study only quantified values for citric and malic acids. Malic acid (553.00 mg 100g-1) was the main acid in the uvaia pulp, and citric acid (455.60 mg 100g-1) was the main acid in the feijoa pulp. It is possible to note that the feijoa pulp showed the highest total sugar content (11.14 g 100g-1) and was the only pulp that contained sucrose. The uvaia pulp, conversely, showed fructose (3.10 g 100g-1) as the main sugar. The results obtained in this study contributed to the valuation and conservation of the species investigated, representing a promising alternative for the use of these native fruits in the development of new products.

ABSTRACT The present report describes the implementation of an emergency operations center to coordinate the response to the COVID-19 pandemic in the municipality of Rio de Janeiro, Brazil. Following the public health emergency management framework proposed by the World Health Organization (WHO), this temporary center (COE COVID-19 RIO) started operating in January 2021. The report is organized along five themes: legal framework; structure, planning, and procedures; institutional articulation; health information for decision-making; and risk communication. Major advances obtained with the initiative include improvements in governance for the management of COVID-19, increase in the synergy among sectors and institutions, improved information sharing in relation to COVID-19 prevention and control measures, innovation in epidemiologic analyses, and gains in transparency and decision-making opportunities. In conclusion, even if conceived at an advanced stage of the pandemic in the municipality of Rio de Janeiro, the COE COVID-19 RIO has played a relevant role in shaping the city’s responses to the pandemic. Also, despite its temporary character, the experience will leave a lasting legacy for the management of future public health emergencies in the municipality of Rio de Janeiro.

RESUMO O presente artigo descreve a experiência de implantação de um centro de operações de emergência (COE) para coordenação da resposta à pandemia de COVID-19 no município do Rio de Janeiro, Brasil. Seguindo o modelo de gestão de emergências em saúde pública preconizado pela Organização Mundial da Saúde (OMS), este centro de caráter temporário (COE COVID-19 RIO) foi ativado em janeiro de 2021. O relato foi estruturado com base em cinco eixos temáticos: arcabouço legal; estrutura, planos e procedimentos; articulações institucionais; informações em saúde para apoio decisório; e comunicação de risco. Entre os avanços importantes relacionados ao estabelecimento desta iniciativa, destacaram-se ganhos em governança para a organização do enfrentamento à COVID-19, aumento da sinergia entre setores e instituições, maior compartilhamento de informações em relação às medidas de prevenção e controle da doença, inovação nas análises epidemiológicas e ganhos na transparência e oportunidade na tomada de decisões. Concluiu-se que, mesmo sendo concebido em estágio avançado da pandemia na cidade, o COE COVID-19 RIO teve papel relevante na estruturação da resposta. Ainda, apesar do caráter temporário do COE, a experiência mostrou-se como importante legado para a condução de futuras emergências em saúde pública no município do Rio de Janeiro.

RESUMEN En el presente artículo se describe la experiencia al establecerse un centro de operaciones de emergencia (COE) para coordinar la respuesta a la pandemia de COVID-19 en el municipio de Rio de Janeiro (Brasil). Siguiendo el modelo de gestión de emergencias de salud pública promovido por la Organización Mundial de la Salud (OMS), este centro temporal se activó en enero del 2021. El informe se estructuró con base en cinco ejes temáticos: marco legal; estructura, planes y procedimientos; articulaciones institucionales; información en materia de salud para sustentar las decisiones; y comunicación sobre riesgos. Entre los principales avances relacionados con esta iniciativa cabe destacar los adelantos en cuanto a la gobernanza para organizar la forma de enfrentar la COVID-19, el aumento de la sinergia entre los sectores y las instituciones correspondientes, un mayor intercambio de información sobre las medidas de prevención y control de la enfermedad, innovación en los análisis epidemiológicos, mayor transparencia en la toma de decisiones y decisiones tomadas de manera más oportuna. Se llegó a la conclusión de que este COE, a pesar de que había sido establecido en una fase avanzada de la pandemia en la ciudad, tuvo un papel importante en la estructuración de la respuesta. Sin embargo, a pesar de su carácter temporal, la experiencia demostró ser un importante legado para enfrentar futuras emergencias de salud pública en el municipio de Rio de Janeiro.
