ABSTRACT. We tested the hypothesis that the increase in soil stiffness, induced by variations in bulk density and water content at the tire-soil contact interface, causes a reduction in the contact area. For this, we examined the contact area from different tire-ground contact scenarios and compared the measurements and simulations using a contact area description model. Front and rear tractor tires were used for the measurement of the contact area under tilled soil, sugarcane field, unpaved road, and paved ground scenarios, which induced different bulk densities and water content levels. The results revealed that soil stiffness reduced the tire-soil contact area. The tire-soil contact area increased as the water content increased and the bulk density was reduced. For the front tractor tire, the theoretical contact area was similar to the values found for tilled soil, but there was a large difference between the measurements (2,200 cm2, for the tilled soil) and the theoretical estimates (3,100 cm2) for the rear tractor tire (likely induced by tire dimensions). Our results suggest that increases in soil stiffness reduce the tire-soil contact area. The higher the soil bulk density and the lower the soil moisture, the lower the contact area. The results also revealed that the tire tractor tread might reduce the contact at the hard surface, making the shape of the contact area more geometrically irregular and different from those predicted by models using regular geometry (e.g., cycles, ellipses, or rectangles). This study suggests that two-body (soil and tire) contact models for deformable surfaces should be used in future tire-soil contact models of agricultural field vehicles.

ABSTRACT The limited temporal completeness and taxonomic accuracy of species lists, made available in a traditional manner in scientific publications, has always represented a problem. These lists are invariably limited to a few taxonomic groups and do not represent up-to-date knowledge of all species and classifications. In this context, the Brazilian megadiverse fauna is no exception, and the Catálogo Taxonômico da Fauna do Brasil (CTFB) (http://fauna.jbrj.gov.br/), made public in 2015, represents a database on biodiversity anchored on a list of valid and expertly recognized scientific names of animals in Brazil. The CTFB is updated in near real time by a team of more than 800 specialists. By January 1, 2024, the CTFB compiled 133,691 nominal species, with 125,138 that were considered valid. Most of the valid species were arthropods (82.3%, with more than 102,000 species) and chordates (7.69%, with over 11,000 species). These taxa were followed by a cluster composed of Mollusca (3,567 species), Platyhelminthes (2,292 species), Annelida (1,833 species), and Nematoda (1,447 species). All remaining groups had less than 1,000 species reported in Brazil, with Cnidaria (831 species), Porifera (628 species), Rotifera (606 species), and Bryozoa (520 species) representing those with more than 500 species. Analysis of the CTFB database can facilitate and direct efforts towards the discovery of new species in Brazil, but it is also fundamental in providing the best available list of valid nominal species to users, including those in science, health, conservation efforts, and any initiative involving animals. The importance of the CTFB is evidenced by the elevated number of citations in the scientific literature in diverse areas of biology, law, anthropology, education, forensic science, and veterinary science, among others. publications problem uptodate up date classifications context exception (CTFB http//fauna.jbrj.gov.br/, httpfaunajbrjgovbr http //fauna.jbrj.gov.br/ , jbrj gov br (http://fauna.jbrj.gov.br/) 2015 Brazil 80 specialists 1 2024 133691 133 691 133,69 125138 125 138 125,13 82.3%, 823 82 3 (82.3% 102000 102 000 102,00 7.69%, 769 7 69 (7.69% 11000 11 11,00 . 3,567 3567 567 (3,56 2,292 2292 2 292 (2,29 1,833 1833 833 (1,83 1,447 1447 447 (1,44 1000 1,00 831 (83 628 (62 606 (60 520 (52 50 users science health biology law anthropology education others http//fauna.jbrj.gov.br/ faunajbrjgovbr //fauna.jbrj.gov.br (http://fauna.jbrj.gov.br/ 201 8 202 13369 13 133,6 12513 12 125,1 82.3% (82.3 10200 10 00 102,0 7.69% 76 6 (7.69 1100 11,0 3,56 356 56 (3,5 2,29 229 29 (2,2 1,83 183 83 (1,8 1,44 144 44 (1,4 100 1,0 (8 62 (6 60 52 (5 5 http//fauna.jbrj.gov.br (http://fauna.jbrj.gov.br 20 1336 133, 1251 125, 82.3 (82. 1020 0 102, 7.69 (7.6 110 11, 3,5 35 (3, 2,2 22 (2, 1,8 18 (1, 1,4 14 4 ( 82.

ABSTRACT Purpose: This study aimed to analyze the diagnostic accuracy of dynamic and static ultrasound (DSUS) in detecting vesicoureteral reflux (VUR) and renal scarring in a cohort of children with neurogenic bladder (NB). Materials and Methods: A retrospective, longitudinal, observational study was conducted using the Reporting Diagnostic Accuracy Studies guideline. The DSUS (index test) data were compared with voiding cystourethrography (VCUG) and renal scintigraphy 99mTc-dimercaptosuccinic (reference tests). Overall performance for predicting VUR and renal scarring was assessed using renal pelvic diameter (RPD)/distal ureteral diameter and renal parenchymal thinning on DSUS, respectively. Results: A total of 107 patients (66 girls, median age 9.6 years) participated. Seventeen patients (15.9%) presented VUR, eight bilateral. For overall reflux grade, the AUC was 0.624 for RPD and 0.630 for distal ureteral diameter. The diagnostic performance for detecting high-grade VUR was slightly better for DSUS parameters. The AUC was 0.666 for RPD and 0.691 for distal ureteral diameter. The cut-offs of 5 mm for RPD and 6.5 mm for distal ureteral diameter presented the best diagnostic odds ratio (DOR) to identify high-grade VUR. The increase of RPD during detrusor contractions showed an accuracy of 89.2%. The thinness of renal parenchyma presented an accuracy of 88% for renal scarring. Conclusion: DSUS predicts VUR and renal scarring in children with NB with fair to good accuracy, and all measurements exhibited a high negative predictive value (NPV). The increase in RPD during voiding or detrusor contractions proved to be the most accurate parameter for indicating the presence of VUR in this study. Purpose (DSUS (VUR NB. .

Abstract Few studies on the distribution of oral diseases in older people are available in the literature. This study aimed to investigate the prevalence and demographic characteristics of oral and maxillofacial lesions in geriatric patients (age ≥ 60 years). A retrospective descriptive cross-sectional study was performed. Biopsy records were obtained from archives of three Brazilian oral pathology centers over a 20-year period. Data on sex, age, anatomical site, skin color, and histopathological diagnosis were collected and analyzed. Pearson’s chi-square test was used to evaluate differences in the frequency of the different oral and maxillofacial lesion groups. A total of 7,476 biopsy records of older patients were analyzed. Most cases were diagnosed in patients aged 60 to 69 years (n = 4,487; 60.0%). Females were more affected (n = 4,403; 58.9%) with a female-to-male ratio of 1:0.7 (p < 0.001). The tongue (n = 1,196; 16.4%), lower lip (n = 1,005; 13.8%), and buccal mucosa (n = 997; 13.7%) were the most common anatomical sites. Reactive and inflammatory lesions (n = 3,840; 51.3%) were the most prevalent non-neoplastic pathologies (p < 0.001), followed by cysts (n = 475; 6.4%). Malignant neoplasms were more frequent (n = 1,353; 18.1%) than benign neoplasms (n = 512; 6.8%). Fibrous/fibroepithelial hyperplasia (n = 2,042; 53.2%) (p < 0.001) and squamous cell carcinoma (n = 1,191; 88.03%) (p < 0.001) were the most common oral lesions in older adults. Biopsy data allow the accurate characterization of the prevalence of oral and maxillofacial lesions, supporting the development of public health policies that can enable the prevention, early diagnosis, and appropriate treatment of these lesions. Also, they bring valuable information that helps dentists and geriatricians diagnose these diseases.

Abstract Introduction Febrile neutropenia (FN) is a serious complication of cancer chemotherapy. The present study aimed to identify risk factors for documented infection in pediatric patients with FN and cancer. Methods This prospective cohort study included patients under 18 years from 2016 to 2018. Infection was defined according to the Centers for Disease Control and Prevention criteria. Results A total of 172 febrile neutropenic episodes were evaluated. From univariate analysis, the risk factors were: female gender; monocyte count < 100 cell/mm³, platelets < 50,000, C-reactive protein (CRP) > 90 mg/dl and hemoglobin < 7mg/dl at the onset of an episode; two or more episodes of FN, and; fever onset; positive blood culture at the fever onset. Independent risk factors according to the multivariate analysis were: CRP at the onset of a febrile episode > 90mg/dl, fever onset and first blood culture with a positive result. The lowest probability of infection was related to first episode and to platelets > 50,000 at the onset of fever. Conclusion A CRP > 90 at the onset of a febrile episode, platelets < 50,000, second episode or more, first fever episode during hospitalization and positive first blood culture were found to be associated with a higher risk of infection and they could be useful for the establishment of risk scores for infection in neutropenic children.

Resumo: Introdução: A mobilidade é uma ação básica praticada durante a execução dos cuidados gerais de enfermagem durante a hospitalização. Contudo, quando se trata de pessoas idosas, essa ação geralmente é polemizada por se constituir um risco para quedas. Objetivo: Apreender a estrutura da representação social da equipe de enfermagem acerca da mobilidade para pessoa idosa hospitalizada. Método: Pesquisa descritiva-exploratória de abordagem qualitativa, fundamentada na Teoria das Representações Sociais, com foco na abordagem estrutural. O grupo social estudado foi composto por 100 profissionais da equipe de enfermagem atuantes em unidades destinadas ao cuidado de pessoas idosas, em um hospital universitário, na cidade de Salvador, Bahia, Brasil. A coleta dos dados ocorreu em dois momentos, através da associação livre de palavras e entrevista não- estruturada. Os dados da associação livre de palavras foram processados pelo software EVOC que determinou a estrutura da representação social através do quadro de quatro casas. Para as entrevistas utilizou-se a análise de conteúdo. A discussão envolveu todo o corpus da pesquisa. Resultados: No quadro, considerando a frequência e a ordem média das evocações, os termos “Queda, Acamado e Cuidado” compuseram o núcleo central. Da análise das entrevistas, surgiram três categorias temáticas: cuidados de mobilidade envolvendo os riscos, cuidados de mobilidade, voltados para manter a independência/autonomia e cuidado para lidar com as barreiras à mobilidade. Para a equipe de enfermagem investigada a representação social da mobilidade está associada a deambulação, com movimentos limitados diante dos riscos de queda que interfere na autonomia e independência. Conclusão: A estrutura das Representações Sociais sobre a mobilidade da pessoa idosa hospitalizada está ancorada em situações do cotidiano da prática profissional do grupo investigado, evidenciando conflitos entre promover prevenção/recuperação da incapacidade pela hospitalização e evitar outros danos à saúde pelo risco de quedas.
Abstract: Introduction: Mobility is a basic action practiced during the execution of general nursing care during hospitalization, however, when it comes to elderly people, this action is usually controversial because it constitutes a risk for falls. Objective: To apprehend the structure of the social representations of the nursing team regarding the mobility of the hospitalized elderly person. Methods: This is exploratory descriptive research with a qualitative approach, based on the principles of the Theory of Social Representations, with a focus on the structural approach. The social group studied was composed of 100 professionals from the nursing team who work in units dedicated to the care of the elderly at a university hospital in the city of Salvador, Bahia, Brazil. Data collection took place in two moments, through the free word association and unstructured interview techniques. The free word association data were processed by the EVOC software, which determined the structure of the social representation through the four-place table. Content analysis was used for the interviews. The discussion involved the entire research corpus. Results: In the table, considering the frequency and the average order of evocations, the terms “fall, bedridden and care” composed the central nucleus. From the analyses of interviews, three thematic categories emerged: Mobility care involving risks, mobility care, aimed at maintaining independence/autonomy and care to deal with barriers to mobility. For the nursing team investigated, the social representation of mobility is associated with ambulation, with limited movements in the face of the risk of falling, which stimulates autonomy and independence. Conclusion: The structure of the Social Representations on the mobility of the hospitalized elderly person is anchored in everyday situations of the professional practice of the investigated group, evidencing conflicts between promoting prevention/recovery of incapacity through hospitalization and avoiding other health damages due to the risk of falls.

Abstract Introduction As the Coronavirus Disease 2019 (COVID-19) pandemic unfolds around the world; answers related to the antibody response against the virus are necessary to develop treatment and prophylactic strategies. We attempted to understand part of the immune response of convalescent plasma donation candidates. Method We carried out a cross-sectional, observational, non-intervention study, testing 102 convalescent plasma donation candidates for antibodies against the virus, relating these data to the time interval between symptom onset and sample collection, age, disease severity, and gender. Results In our sample, the individuals who developed a greater antibody response were the ones who had a longer time interval between symptom onset and sample collection, the ones who had been hospitalized and the subjects above 35 years old. Moreover, 17 individuals did not present any reactive antibodies. Conclusion These results are important in that they raise questions about the role of the humoral response against the virus, as some individuals do not develop antibodies to fight it. In addition, they help develop recruitment strategies for convalescent plasma donors, who should be asymptomatic for at least 21 days and are possibly more likely to have reactive antibodies after 35 days without symptoms.

ABSTRACT Purpose: To study the influence of silver nanoparticles (AgNP) on tissue reaction when incorporated into a polymeric matrix of polyacrylic acid-based (Carbopol®) gel as a proposal for a new low-cost type of biomaterial that is simple to manufacture for use as an antimicrobial and antioxidative dressing. Methods: In-vivo tests of implantation in the subcutaneous tissue of the back of rats were performed using polyethylene tubes in three situations: empty, only the gel, and gel incorporated with AgNP. Then, the tissue reaction was studied by counting inflammatory cells. Additionally, in-vitro tests of the antioxidative and antimicrobial activity of AgNP were performed. The radical 2,2 diphenyl-1 picrylhydrazyl (DPPH) was used to test the antioxidative activity of AgNP using electron spin resonance. The antimicrobial activity of AgNP was determined by minimum inhibitory concentration against the microorganisms: Staphylococcus aureus, Pseudomonas aeruginosa, and Escherichia coli. Results: The results indicated that AgNP presents antioxidative activity and was able to inhibit the growth of the microorganisms tested. The addition of AgNP in Carbopol® did not alter the tissue inflammatory response (p>0.05, Kruskal-Wallis’s test). Conclusions: The new biomaterial is promising for future use as a dressing for its beneficial properties for regenerative processes.

RESUMO Estudo prospectivo, randomizado e duplo-cego com o objetivo de comparar dois protocolos diferentes utilizados para o preparo de cólon em pacientes que realizaram colonoscopia: solução de Manitol; e solução de Picossulfato de Sódio combinado com Óxido de Magnésio. Para avaliar qual protocolo proporciona melhores resultados, 90 pacientes do ambulatório de proctologia da Unidade de Cirurgia Geral do Hospital Regional da Asa Norte (HRAN) compuseram a amostra deste estudo. Tanto os pacientes quanto o colonoscopista não tiveram prévio conhecimento da substância utilizada para o preparo do cólon, a qual foi distribuída randomicamente entre os participantes. Os dois protocolos demonstraram bons e semelhantes resultados acerca da eficiência do preparo do cólon, embora a literatura estudada tenha demonstrado diferença significativa em favor do preparo feito com solução de Manitol em relação a limpeza do cólon durante o exame. Em consonância com a literatura, os pacientes que utilizaram solução de Manitol apresentaram mais efeitos colaterais, destacando-se a diferença significativa encontrada para vômito e distúrbios do sono. O preparo com Picossulfato de Sódio com Óxido de Magnésio foi relevantemente superior em relação à facilidade de ingestão percebida pelos pacientes.
ABSTRACT This prospective, randomized and double-blind study aims to compare two different protocols used for bowel preparation in patients scheduled for colonoscopy. The protocols were composed by solutions of Mannitol or sodium picosulfate combined with magnesium oxide. Patients from the proctology outpatient clinic of the General Surgery Unit of the Regional Hospital of Asa Norte (HRAN) comprised the sample of this study. Both the patients and the colonoscopist had no prior knowledge of the substance used to prepare bowel, which was randomly distributed among the participants. Both protocols demonstrated good and similar results regarding the efficiency of colon preparation, although the review of literature shows a difference in favor of preparation made with Mannitol solution regarding the colon neatness during the exam. In line with the literature, patients who used Mannitol solution had more side effects, highlighting the significant difference found for vomiting and sleep impairment. The preparation with Sodium Picosulfate with Magnesium Oxide was significantly superior in relation to the ease of ingestion perceived by the patients.

ABSTRACT The aim of this study was to compare low- and high-viscosity bulk-fill composites for Knoop microhardness (KHN), microtensile bond strength (MTBS) to dentin in occlusal cavities, and fracture strength (FS) in molars with mesialocclusal- distal restoration. Disk-shaped samples with different thicknesses (2 or 4 mm) of low-viscosity (SDR Flow, Dentsply) and high-viscosity bulk-fill composites (Filtek BulkFill, 3M ESPE; and Tetric-N Ceram Bulk Fill, Ivoclar Vivadent) were prepared for top and bottom KHN analysis (n=10). MTBS to dentin and fracture pattern was evaluated in human molars with occlusal cavities restored with (n=10): conventional nanocomposite (Z350XT, 3M ESPE), low-viscosity (Filtek Bulk-fill Flow, 3M ESPE) or high-viscosity bulk-fill composites (Filtek BulkFill). The FS and fracture pattern of human molar with mesial-occlusal-distal restorations submitted or not to thermomechanical cycling were investigated (n=10) using: intact tooth (control), and restoration based on conventional microhybrid composite (Z250, 3M ESPE), low-viscosity (SDR Flow) or high-viscosity bulk-fill composites (Filtek BulkFill). The data were submitted to split-plot ANOVA (KHN), one-way ANOVA (MTBS), two-way ANOVA (FS) followed by Tukey’s test (α=0.05). For KHN, there was no significant difference for the resin composites between the top and bottom. For MTBS, no significant differences among the materials were detected; however, the low-viscosity composite presented lower frequency of adhesive failures. For FS, there was no significant difference between composites and intact tooth regardless of thermomechanical cycling. Low- and high-viscosity bulk-fill composites have comparable microhardness and microtensile bond strength when used in occlusal restorations. Likewise, the bulk-fill composites present similar fracture strength in molars with mesio-occlusal-distal restorations.
RESUMO O objetivo deste estudo foi comparar resinas compostas bulk- -fill de baixa e alta viscosidade quanto à microdureza Knoop (KHN), resistência de união a microtração (MTBS) em cavidades oclusais e carga à fratura (FS) em molares com restauração mesio-oclusal-distal. Amostras em forma de disco com diferentes espessuras (2 ou 4 mm) de resinas bulk-fill de baixa viscosidade (SDR Flow, Dentsply) e alta viscosidade (Filtek BulkFill, 3M ESPE; e Tetric-N Ceram Bulk Fill, Ivoclar Vivadent) foram obtidas para análise de KHN no topo e na base (n = 10). A MTBS em dentina e o padrão de fratura foram avaliados em molares humanos com cavidades oclusais restauradas com (n = 10): resina composta nanoparticulada convencional (Z350XT, 3M ESPE), resinas bulk-fill de baixa viscosidade (Filtek Bulk-fill Flow, 3M ESPE) ou alta viscosidade (Filtek BulkFill). Foram investigados a FS e o padrão de fratura de molares humanos em restaurações mesial-ocluso-distais sub metidas ou não à ciclagem termomecânica (n = 10), sendo: dente íntegro (controle), e restaurações baseadas em resina composta microhíbrida convencional (Z250, 3M ESPE); resinas bulk-fill de baixa viscosidade (SDR Flow) ou alta viscosidade (Filtek BulkFill). Os dados foram submetidos a split-plot ANOVA (KHN), one-way ANOVA (MTBS), two-way ANOVA (FS) seguidos do teste de Tukey (α = 0,05). Para KHN, não houve diferença significativa entre o topo e a base para as resinas compostas. Para MTBS, não foram detectadas diferenças significativas entre os materiais; entretanto, a resina bulk-fill de baixa viscosidade apresentou menor frequência de falhas adesivas. Para FS, não houve diferença significativa entre os materiais e o dente íntegro, independentemente da ciclagem termomecânica. As resinas bulk-fill de baixa e alta viscosidade têm microdureza e resistência à microtração comparáveis quando usados em restaurações oclusais. Da mesma forma, as resinas bulk-fill apresentam resistência à fratura semelhante em molares com restaurações mesio-oclusal-distais.

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.

Resumo Objetivos: investigar as informações recebidas pela gestante considerando fatores assis-tenciais e educacionais sobre sífilis e a suas associações com o diagnóstico de sífilis congênita em uma maternidade de referência. Métodos: estudo caso-controle realizado em maternidade de referência em Minas Gerais, Brasil, de 2017 a 2018. Grupo caso incluiu mães de recém-nascidos com sífilis congênita presuntiva e o grupo Controle foi considerado mães de recém-nascidos saudáveis. Variáveis clínicas, obstétricas e informações sobre a abordagem educacional materna sobre a sífilis durante a assistência no pré-natal foram obtidas por meio de entrevista e prontuário. Análises descritivas e comparativas foram realizadas. Calculou-se o teste do qui-quadrado ou exato de Fisher e a razão de chances, seguido de regressão logística multivariada. Resultados: sessenta mães foram incluídas no grupo caso e 120 mães foram incluídas no grupo controle. As mães do grupo caso apresentavam menor escolaridade e tiveram 24 vezes mais chances de ter informações sobre os riscos da sífilis congênita e cinco vezes mais chances de ter recebido tratamento anterior para sífilis e as mães do grupo controle tiveram 10 vezes mais chances de receber informações sobre as Infecções Sexualmente Transmissíveis durante a assistência no pré-natal. Conclusão: a assistência a saúde adequada identificando história previa de sífilis da gestante e educação em saúde com melhores informações sobre Infecções Sexualmente Transmissíveis podem ajudar na prevenção de sífilis congênita, o que indica necessidade de melhor abordagem pelos profissionais durante a assistência pré-natal.
Abstract Objectives: to investigate the information received by pregnant women considering assistance care and educational factors on syphilis and its association with the diagnostic of congenital syphilis in a referral maternity. Methods: a case-control study conducted in a referral maternity in Minas Gerais, Brazil, from 2017 to 2018. A case group included newborns’ mothers with presumptive congenital syphilis and A control group was considered healthy newborns ’ mothers. Clinical, obstetrics variables and information about maternal educational approach on syphilis during prenatal care were obtained through interviews and medical records. Descriptive and comparative analyses were performed. Chi-square or Fisher's exact test and odds ratio were calculated followed by multivariate logistic regression. Results: sixty mothers were included in the case group and 120 mothers in the control group. Mothers in the case group presented lower schooling level and they were 24 times more likely to have information about the risks of congenital syphilis and five times more likely to had received previous treatment for syphilis and mothers in the control group were 10 times more likely to receive information about Sexually Transmitted Infections during prenatal care. Conclusion: adequate health assistance identifying previous history of syphilis and health education improving its information about Sexually Transmitted Infections can help prevent congenital syphilis, which indicates the necessity of a better approach by the professionals during prenatal care.

ABSTRACT The plasmid-mediated colistin-resistance gene named mcr-1 has been recently described in different countries and it became a public health challenge. Of note, few studies have addressed the spread of Escherichia coli harboring the mcr-1 gene in both, community and hospital settings. A total of seven colistin-resistant E. coli carrying mcr-1, collected from 2016 to 2018, from community (n=4), healthcare-acquired infections (n=2) and colonization (n=1) were identified in three high complexity hospitals in Sao Paulo, Brazil. These colistin-resistant isolates were screened for mcr genes by PCR and all strains were submitted to Whole Genome Sequencing and the conjugation experiment. The seven strains belonged to seven distinct sequence types (ST744, ST131, ST69, ST48, ST354, ST57, ST10), and they differ regarding the resistance profiles. Transference of mcr-1 by conjugation to E. coli strain C600 was possible in five of the seven isolates. The mcr-1 gene was found in plasmid types IncX4 or IncI2. Three of the isolates have ESBL-encoding genes (blaCTX-M-2, n=2; blaCTX-M-8, n=1). We hereby report genetically distinct E. coli isolates, belonging to seven STs, harboring the mcr-1 gene, associated to community and healthcare-acquired infections, and colonization in patients from three hospitals in Sao Paulo. These findings point out for the potential spread of plasmid-mediated colistin-resistance mechanism in E. coli strains in Brazil.

OBJECTIVES: We designed a cohort study to describe characteristics and outcomes of patients with coronavirus disease (COVID-19) admitted to the intensive care unit (ICU) in the largest public hospital in Sao Paulo, Brazil, as Latin America becomes the epicenter of the pandemic. METHODS: This is the protocol for a study being conducted at an academic hospital in Brazil with 300 adult ICU beds dedicated to COVID-19 patients. We will include adult patients admitted to the ICU with suspected or confirmed COVID-19 during the study period. The main outcome is ICU survival at 28 days. Data will be collected prospectively and retrospectively by trained investigators from the hospital’s electronic medical records, using an electronic data capture tool. We will collect data on demographics, comorbidities, severity of disease, and laboratorial test results at admission. Information on the need for advanced life support and ventilator parameters will be collected during ICU stay. Patients will be followed up for 28 days in the ICU and 60 days in the hospital. We will plot Kaplan-Meier curves to estimate ICU and hospital survival and perform survival analysis using the Cox proportional hazards model to identify the main risk factors for mortality. ClinicalTrials.gov: NCT04378582. RESULTS: We expect to include a large sample of patients with COVID-19 admitted to the ICU and to be able to provide data on admission characteristics, use of advanced life support, ICU survival at 28 days, and hospital survival at 60 days. CONCLUSIONS: This study will provide epidemiological data about critically ill patients with COVID-19 in Brazil, which could inform health policy and resource allocation in low- and middle-income countries.

Resumo A pesquisa objetivou conhecer a percepção ambiental de pescadores da Ilha de Itaoca acerca dos efeitos do avanço urbano/industrial na Baía de Guanabara sobre seus espaços de pesca e moradia. Por meio da pesquisa qualitativa exploratória puderam ser entendidas as interações desses pescadores com o espaço em que estão inseridos na Baía de Guanabara e que percepções fazem das externalidades que chegam à sua comunidade. Os resultados apontaram que o avanço urbano/industrial, resultante do atual ciclo de desenvolvimento regional relacionado ao petróleo, vem se constituindo numa ameaça à sobrevivência da atividade pesqueira, tanto pelos impactos ambientais aos ecossistemas da região que a prejudicam significativamente, como pela pressão exercida sobre seus espaços de moradia e de pesca.
Abstract The objective of this research was to obtain the environmental perception of fishermen of Itaoca Island regarding the effects of urban/industrial expansion in Guanabara Bay on their fishing and housing spaces. Through exploratory qualitative research, it was possible to understand the interactions of these fishermen with the space in which they are inserted in Guanabara Bay and their perceptions on the externalities that reach their community. The results showed that the urban/industrial advance, resulting from the current cycle of regional development related to petroleum, has been a threat to the survival of fishing activity, both by the environmental impacts to the region’s ecosystems that significantly damage it, and by the pressure exerted on their living and fishing spaces.
