Toward an Integrated View of Operational Tolerance in Human Renal Transplantation: A Systems Biology Perspective.

Operational tolerance (OT) is the phenomenon occurring in human renal and liver transplantation in which the body does not reject the organ after discontinuing immunosuppression for at least a year. We revisited the data generated by The Brazilian Multicenter Study on Operational Tolerance involving different conceptual fields - antigen-specific cytokine response, immune cell numbers and repertoire, signaling pathways, and epigenetics. We integrated our data to pave the way to systems biology thinking and harness debate on potential mechanisms in OT. We present original data on systems biology in OT, connecting potential mechanistic players. Using bioinformatics, we identified three dominant features that discriminate OT from its opposing clinical outcome, chronic rejection (CR). The OT-CR discriminative molecules were FOXP3, GATA3 and STAT6, each corresponding to a differential profile: (1) In FOXP3, OT presents preserved regulatory T cell (Treg) numbers but decreased numbers in CR; (2) in GATA3, increased expression is seen in OT; and (3) in STAT6, decreased monocyte activation is seen in OT. With these variables, we built molecular networks to identify interactions related to OT versus CR. Our first systems biology endeavor gave rise to novel potentially relevant interconnected players in OT mechanisms: FOXP3 connecting to interleukin-9 (IL-9) and IL-35 signaling, suggesting their immunoregulatory involvement in OT. Likewise, GATA3/FOXP3 interactions incrementing/stabilizing FOXP3 transcription suggest participation in keeping healthy FOXP3+ Tregs in OT. We envision that systems biology thinking will greatly contribute to advancing knowledge in human transplantation tolerance in an interactive perspective.

Regulatory/inflammatory cellular response discrimination in operational tolerance.

BACKGROUND: Antigen-specific cellular response is essential in immune tolerance. We tested whether antigen-specific cellular response is differentially modulated in operational tolerance (OT) in renal transplantation with respect to critical antigenic challenges in allotransplantation-donor antigens, pathogenic antigens and self-antigens. METHODS: We analysed the profile of immunoregulatory (REG) and pro-inflammatory (INFLAMMA) cytokines for the antigen-specific response directed to these three antigen groups, by Luminex. RESULTS: We showed that, in contrast to chronic rejection and healthy individuals, OT gives rise to an immunoregulatory deviation in the cellular response to donor human leucocyte antigen DR isotype peptides, while preserving the pro-inflammatory response to pathogenic peptides. Cellular autoreactivity to the N6 heat shock protein 60 (Hsp60) peptide also showed a REG profile in OT, increasing IL4, IL-5, IL-10 and IL-13. CONCLUSIONS: The REG shift of donor indirect alloreactivity in OT, with inhibition of interleukin (IL)-1B, IL-8, IL-12, IL-17, granulocyte colony-stimulating factor, Interferon-γ and monocyte chemoattractant protein-1, indicates that this may be an important mechanism in OT. In addition, the differential REG profile of cellular response to the Hsp60 peptide in OT suggests that REG autoimmunity may also play a role in human transplantation tolerance. Despite cross-reactivity of antigen-specific T cell responses, a systemic functional antigen-specific discrimination takes place in OT.

Screening Aedes aegypti (Diptera: Culicidae) Populations From Pernambuco, Brazil for Resistance to Temephos, Diflubenzuron, and Cypermethrin and Characterization of Potential Resistance Mechanisms.

Resistance to chemical insecticides detected in Aedes aegypti (L.) mosquitoes has been a problem for the National Dengue Control Program (PNCD) over the last years. In order to provide deeper knowledge of resistance to xenobiotics, our study evaluated the susceptibility profile of temephos, diflubenzuron, and cypermethrin insecticides in natural mosquito populations from the Pernambuco State, associating these results with the local historical use of such compounds. Furthermore, mechanisms that may be associated with this particular type of resistance were characterized. Bioassays with multiple temephos and diflubenzuron concentrations were performed to detect and quantify resistance. For cypermethrin, diagnostic dose assays were performed. Biochemical tests were carried out to quantify the activity of detoxification enzymes. In addition, a screening of mutations present in the voltage-gated sodium channel gene (NaV) was performed in samples previously submitted to bioassays with cypermethrin. The populations under study were resistant to temephos and showed a positive correlation between insecticide consumption and the resistance ratio (RR) to the compound. For diflubenzuron, the biological activity ratio (BAR) ranged from 1.3 to 4.7 times, when compared to the susceptible strain. All populations showed resistance to cypermethrin. Altered enzymatic profiles of alpha, p-nitrophenyl acetate (PNPA) esterases and glutathione-S-transferases were recorded in most of these samples. Molecular analysis demonstrated that Arcoverde was the only population that presented the mutated form 1016Ile/Ile. These findings show that the situation is critical vis-à-vis the effectiveness of mosquito control using chemical insecticides, since resistance to temephos and cypermethrin is widespread in Ae. aegypti from Pernambuco.

Antimicrobial Resistance in Streptococcus pneumoniae before and after the Introduction of Pneumococcal Conjugate Vaccines in Brazil: A Systematic Review.

Streptococcus pneumoniae causes serious illnesses, such as pneumonia, bacteremia, and meningitis, mainly in immunocompromised individuals and those of extreme ages. Currently, pneumococcal conjugate vaccines (PCVs) are the best allies against pneumococcal diseases. In Brazil, the 10-valent and 13-valent PCVs have been available since 2010, but the threat of antimicrobial resistance persists and has been changing over time. We conducted a systematic review of the literature with works published since 2000, generating a parallel between susceptibility data on isolates recovered from colonization and invasive diseases before and after the implementation of PCVs for routine childhood use in Brazil. This systematic review was based on the Cochrane Handbook for Systematic Reviews of Interventions and Preferred Reporting Items for Systematic Literature Reviews and Meta-Analyses (PRISMA) guidelines. Despite the inclusion of PCVs at a large scale in the national territory, high frequencies of non-susceptibility to important drugs used in pneumococcal diseases are still observed, especially penicillin, as well as increasing resistance to macrolides. However, there are still drugs for which pneumococci have a comprehensive sensitivity profile.

CRISPR-Cas systems in enterococci.

Enterococci are members of the microbiota of humans and other animals. They can also be found in the environment, associated with food, healthcare infections, and hospital settings. Due to their wide distribution, they are inserted in the One Health context. The selective pressure caused by the extensive use of antimicrobial agents in humans, animals, and agriculture has increased the frequency of resistance to various drugs among enterococcal species. CRISPR-Cas system, an important prokaryotic defense mechanism against the entry of mobile genetic elements, may prevent the acquisition of genes involved in antimicrobial resistance and virulence. This system has been increasingly used as a gene editing tool, which can be used as a way to recognize and inactivate genes of interest. Here, we conduct a review on CRISPR systems found in enterococci, considering their occurrence, structure and organization, mechanisms of action and use as a genetic engineering technology. Type II-A CRISPR-Cas systems were shown to be the most frequent among enterococcal species, and the orphan CRISPR2 was the most commonly found system (54.1%) among enterococcal species, especially in Enterococcus faecalis. Distribution of CRISPR systems varied among species. CRISPR systems had 1 to 20 spacers, with size between 23 and 37 bp and direct repeat sequences from 25 to 37 bp. Several applications of the CRISPR-Cas biotechnology have been described in enterococci, mostly in vitro, using this editing tool to target resistance- and virulence-related genes.

Long-term predominance in childhood colonization of the multidrug-resistant lineage 6C/ST386 of Streptococcus pneumoniae after universal immunization with the 10-valent pneumococcal conjugate vaccine in Brazil.

BACKGROUND: A study conducted in the city of Niterói/RJ, four years after the introduction of the pneumococcal conjugate vaccine in Brazil, reported the emergence of non-vaccine serotype 6C Streptococcus pneumoniae associated with carriage in children. The multidrug-resistant (MDR) lineage ST386 was predominant among 6C isolates. A subsequent study, in 2019, reported the continued prevalence of 6C as the main serotype. This study aims to determine the genetic lineages of serotype 6C S. pneumoniae obtained from the 2019 study and evaluate the status of ST386 in this population. METHODS: Serotype 6C S. pneumoniae isolates were obtained during the 2019 study. Lineages were determined by MLST and changes in ST386 status between 2014 and 2019 were verified by a two-tailed Fisher's exact test. RESULTS: Of the 16 serotype 6C isolates recovered during 2019, 10 (62.5 %) belonged to ST386, remaining predominant in the population. The second most frequent was ST2777 represented by four (25 %) isolates. Both ST63 and ST3280 only had one (6.25 %) isolate each. Comparison of ST386 proportion between 2014 and 2019 showed no significant changes within the population. CONCLUSIONS: This study was able to confirm the stability on the occurrence of the MDR lineage ST386 in children in our setting nine years after the introduction of PCV10 in Brazil.

Responding to STI epidemics among young people: a characterization of the language employed in educational materials. / Enfrentamento de epidemias de ISTs em população jovem: caracterização da linguagem dos materiais educativos.

This article aims to characterize the language employed in educational and communications materials about STIs, HIV/AIDS and viral hepatitis produced by the Ministry of Health between 2010 and 2019, identifying elements related to health promotion and disease prevention. We conducted an exploratory descriptive study. The materials were selected by performing a systematic search of the Ministry of Health website focusing on the period 2010-2019. The materials were analyzed to determine the educational approaches adopted. The preventive, educational and personal development approaches were identified in 100% (201), 24.87% (50) and 7.96% (16) of the materials, respectively. The radical and popular education for health approaches were not observed. The almost exclusive focus on the preventive approach reveals that promoting changes in individual habits and behavior alone is not sufficient to combat and solve the problem of STIs, HIV/AIDS and viral hepatitis in Brazil.

O objetivo do artigo é caracterizar a linguagem utilizada nos materiais educativos e comunicacionais vinculados à temática das IST, do HIV/Aids e hepatites virais produzidos e veiculados pelo Ministério da Saúde no período de 2010 a 2019, identificando elementos de promoção à saúde e de prevenção de doenças. Metodologia descritiva exploratória para a caracterização da linguagem utilizada nos materiais educativos e comunicacionais sobre as IST, do HIV/Aids e hepatites virais. Para a seleção dos materiais educativos, adotou-se a estratégia de busca sistemática realizada no site do Ministério da Saúde do Brasil por um período de dez anos: de 2010 a 2019. Os materiais foram observados por meio dos enfoques educativos. O enfoque preventivo foi identificado em 100% dos materiais analisados (201). O enfoque educativo foi encontrado em 24,87% (50) dos materiais, e o enfoque de desenvolvimento pessoal foi encontrado em 7,96% (16). Os enfoques radical e da educação popular em saúde não foram observados. A atenção quase exclusiva ao enfoque preventivo revela que cuidados individuais isoladamente não são suficientes para combater e sanar o problema das IST, do HIV/Aids e das hepatites virais no Brasil.

Telehealth and Speech Therapy: usability assessment of an orientation and prevention program of orofacial myofunctional changes, during the COVID-19 pandemic.

PURPOSE: To assess the effect of an virtual speech-language orientation program, as well as the prevention of orofacial myofunctional alterations. METHODS: Fifty-five volunteer residents aged between 18 and 50 years of age residents of Federal District participated in the study, 14 men and 41 women with an average of 28. The orientation program was divided into five stages (1) The preparation of material to be used in the orientation program, (2) The completion of a semi-structured questionnaire made available through Google Forms, (3) Completion of a pre-orientation program questionnaire, (4) utilization of the speech therapy orientation program, (5) Completion of the post-orientation program questionnaire. To analyze the results the McNemar statistical test was used considering the absolute frequency (N), enabling comparison through a paired sample. The significance level adopted was 5%. RESULTS: Statistically significant differences were seen in 10 of the 19 questions asked in the pre and post-orientation program questionnaires, proving the effect of the orientation program and improvement in participants' knowledge. In addition the participants were satisfied with the program and the content. CONCLUSION: The orientation program focused on health promotion and prevention of orofacial myofunctional alterations and combined with telehealth brought significant changes to the reality of the participants, favoring the quality of life of these individuals and changing their reality.

Prevalence, capsular types, antimicrobial resistance and risk factors associated with pneumococcal carriage among children after long-term 10-valent pneumococcal conjugate vaccine use in Brazil.

BACKGROUND: The 10-valent pneumococcal conjugate vaccine (PCV10) was introduced for childhood vaccination in Brazil's National Immunization Program in 2010. After nine years of PCV10 use, we investigated the carriage prevalence, capsular types, antimicrobial resistance and risk factors among children living in Niterói city, RJ, Brazil. METHODS: Between September and December 2019, we conducted a cross-sectional study and recruited children under 6 years of age. Antimicrobial susceptibility was evaluated by the disk-diffusion method and MICs to beta-lactams and macrolides were determined by E-test®. Capsular types were deduced by multiplex PCR. Logistic regression was used to predict risk factors for pneumococcal carriage. RESULTS: Seventy-five (17.4%) of the 430 children were pneumococcal carriers. The most frequent capsular types were 6C/D (14.7%), 11A/D (13.3%), and 23B (9.3%). PCV10 serotypes represented 5.3%. All isolates were susceptible to levofloxacin, linezolid, rifampicin, and vancomycin. Penicillin non-susceptible pneumococci (PNSP) made up 37.3%, with penicillin and ceftriaxone MICs ranging from 0.12 to 4.0 µg/ml and 0.064-4.0 µg/ml, respectively. Of the 19 (25.3%) erythromycin-resistant (ERY-R) isolates (macrolide MICs of 6 to >256 µg/ml), most had the cMLSB phenotype (84.2%) and carried the erm(B) gene (73.7%). We detected 17 (22.6%) multidrug-resistant (MDR) isolates, strongly associated with serotype 6C/D. Presence of any symptoms, chronic diseases, childcare center attendance, living with young siblings, slum residence, and unstable income were predictors of pneumococcal carriage. CONCLUSIONS: Long-term universal childhood use of PCV10 has nearly eliminated carriage with PCV10 serotypes, but the high frequency of MDR isolates, especially associated with serotype 6C/D, remains a concern. Replacing PCV10 with PCV13 should reduce the proportion of ERY-R isolates and PNSP by at least 14% and 18%, respectively.

[Prevalence of respiratory symptoms in areas of the Federal District, Brazil]. / Prevalência de sintomáticos respiratórios em regiões do Distrito Federal, Brasil.

The identification of individuals with respiratory symptoms (RS) is important for the early detection of tuberculosis. The aim of this study was to estimate the prevalence of RS in three administrative regions of the Federal District, Brazil. For this, we used the 30 by 7 cluster sampling technique proposed by the World Health Organization. Individuals with RS were defined as those aged 15 years or older living in the administrative regions of Estrutural, Itapoã, or Varjão and reporting a cough lasting at least 3 weeks at the date of the interview. The prevalence of RS was 5.7% in Estrutural and Varjão (95% CI: 2.4-9.0) and 4.8% in Itapoã (95%CI: 1.6-7.9), with a design effect close to 1.0. In Estrutural and Itapoã, fewer years of schooling, and in Itapoã and Varjão, lower income, were associated with RS. Cigarette smoking was associated with the presence of RS in all regions. The prevalence of RS in the three administrative regions investigated is consistent with that of other areas with a similar socioeconomic profile.

Assessment of safety culture in organ donation.

OBJECTIVES: To evaluate the perception of safety culture by health professionals who work with organ and tissue donation. METHODS: A quantitative, descriptive study developed with 185 health professionals who act directly and indirectly with organ and tissue donation from two hospitals in the South of Brazil. The data collection was performed between January and July 2017 by using the Safety Attitudes Questionnaire. The analysis took place through descriptive statistics. RESULTS: The mean score of the domains evaluated ranged from 41.6, for Perception of management of the unit, and 80.9 for Job satisfaction. Positive perception of safety culture in this study was evidenced only for Job satisfaction with a score higher than 75. CONCLUSIONS: Of the six domains evaluated, only one had a positive score, evidencing the need to elaborate effective strategies for implanting safety culture in these institutions.

Laser therapy increases the proliferation of preosteoblastic MC3T3-E1 cells cultured on poly(lactic acid) films.

This study aimed to verify the efficacy of low-level laser irradiation (LLLI) on the proliferation of MC3T3-E1 preosteoblasts cultured on poly(lactic acid) (PLA) films. The produced films were characterized by contact angle tests, scanning electron microscopy (SEM), atomic force microscopy, differential scanning calorimetry, and X-ray diffraction. The MC3T3-E1 cells were cultured as three different groups: Control-cultured on polystyrene plastic surfaces; PLA-cultured on PLA films; and PLA + Laser-cultured on PLA films and submitted to laser irradiation (660 nm; 30 mW; 4 J/cm2 ). Cell proliferation was analyzed by Trypan blue and Alamar blue assays at 24, 48, and 72 h after irradiation. Cell viability was assessed by Live/Dead assay, apoptosis-related events were evaluated by Annexin V/propidium iodide (PI) expression, and cell cycle events were analyzed by flow cytometry. Cell morphology on the surface of films was assessed by SEM. Cell counting and biochemical assay results indicate that the PLA + Laser group exhibited higher proliferation (p < 0.01) when compared with the Control and PLA groups. The Live/Dead and Annexin/PI assays indicate increased cell viability in the PLA + Laser group that also presented a higher percentage of cells in the proliferative cell cycle phases (S and G2/M). These findings were also confirmed by the higher cell density observed in the irradiated group through SEM images. The evidence from this study supports the idea that LLLI increases the proliferation of MC3T3-E1 cells on PLA surfaces, suggesting that it can be potentially applied in bone tissue engineering.

Differential microRNA Profile in Operational Tolerance: A Potential Role in Favoring Cell Survival.

Background: Operational tolerance (OT) is a state of graft functional stability that occurs after at least 1 year of immunosuppressant withdrawal. MicroRNAs (microRNA) are small non-coding RNAs that downregulate messenger RNA/protein expression of innumerous molecules and are critical for homeostasis. We investigated whether OT in kidney transplantation displays a differential microRNA profile, which would suggest that microRNAs participate in Operational Tolerance mechanisms, and may reveal potential molecular pathways. Methods: We first compared serum microRNA in OT (n = 8) with chronic rejection (CR) (n = 5) and healthy individuals (HI) (n = 5), using a 768-microRNA qPCR-panel. We used the Thermo Fisher Cloud computing platform to compare the levels of microRNAs in the OT group in relation to the other study groups. We performed validation experiments for miR-885-5p, by q-PCR, in a larger number of study subjects (OT = 8, CR = 12, HI = 12), as individual samples. Results: We detected a differential microRNA profile in OT vs. its opposing clinical outcome-CR-suggesting that microRNAs may integrate transplantation tolerance mechanisms. Some miRNAs were detected at higher levels in OT: miR-885-5p, miR-331-3p, miR-27a-5p vs. CR; others, we found at lower levels: miR-1233-3p, miR-572, miR-638, miR-1260a. Considering highly predicted/experimentally demonstrated targets of these miRNAs, bioinformatics analysis revealed that the granzyme B, and death receptor pathways are dominant, suggesting that cell death regulation integrates transplantation tolerance mechanisms. We confirmed higher miR-885-5p levels in OT vs. CR, and vs. HI, in a larger number of subjects. Conclusions: We propose that epigenetics mechanisms involving microRNAs may integrate human transplantation tolerance mechanisms, and regulate key members of the cell death/survival signaling. miR-885-5p could favor cell survival in OT by diminishing the levels of CRADD/RAIDD and CASP3. Nonetheless, given the nature of any complex phenomenon in humans, only cumulative data will help to determine whether this microRNA differential profile may be related to the cause or consequence of operational tolerance.

Changing the molecular profile of primary and metastatic breast cancer identified by Foundation One: case report

Objective: To describe a case report of a patient who presented with bilateral breast cancer with progression to metastatic disease, in which immunohistochemical profile of the primary and metastatic tumor was divergent. Methods: This was a study with a descriptive narrative and reflective design, of the case report type, based on secondary data, with information and images obtained from the electronic medical records of the MVSoul system used in the oncology center of a private hospital in the Federal District in Brazil. Data collection was derived from the analysis of data and images of the electronic medical record. Case report: A patient presented with bilateral metastatic breast cancer, and the primary and metastatic breast tumors showed a difference in immunohistochemical profile. Accordingly, we highlight the rarity of the case, the need for biopsies of metastatic lesions because of the molecular heterogeneity of breast cancer and possible discrepancy between the primary tumor and metastases. Spreading knowledge about diagnostic tests and personalized treatment according to tumor molecular characteristics is also essential, especially when the patient does not have a satisfactory therapeutic response, as in the reported case, since the patient had metastases with different molecular profiles confirmed only by of tumor DNA sequencing.

Deaths from HIV/AIDS in aged adults in the Federal District: an analysis from 2007 to 2016 / Óbitos por HIV/AIDS em idosos no Distrito Federal: uma análise de 2007 a 2016

Introduction: Infection with the human immunodeficiency virus/acquired immunodeficiency syndrome (HIV/AIDS) in Brazil experienced a significant increase in the last decade among individuals aged over 60 years. This scenario indicates the need to know the mortality profile from AIDS in aged adults, in order to promote educational and preventive actions, in addition to professional development to improve the care provided to these patients. Objective: To describe the epidemiological profile of aged adults who died of AIDS in the Federal District (FD) from 2007 to 2016. Methods: This is a descriptive ecological study, based on secondary data from the Brazilian Mortality Information System, obtained through the Health Situation Analysis and Data Management of the Health Department of the FD. The analysis was carried out in the Statistical Package for the Social Sciences (SPSS). Results: Deaths occurred more frequently among men (74.1%), especially those aged from 60 to 69 years (70.4%). The gender ratio was 2.85. Most of them only had primary school education (42.0%), were married or in a common-law marriage (43.0%), and were white/Caucasian (52%). Regarding the place of residence, Plano Piloto was the place with the highest incidence (45.7%), followed by Ceilândia (12.3%) and Taguatinga (8.6%). Conclusion: It was found that AIDS, among aged adults, follows the national trend, occurring most frequently in older males, demonstrating that it is necessary to improve the implementation of prevention practices among this population. It is necessary to better study AIDS-related stigma and prejudice barriers, both among older adults and health professionals, to overcome them, to increase life expectancy of these patients and to improve their quality of life.

Introdução: A infecção pelo vírus da imunodeficiência humana/síndrome da imunodeficiência adquirida (HIV/AIDS) no Brasil experimentou um aumento importante na última década entre os indivíduos com mais de 60 anos. Esse cenário aponta a necessidade de se conhecer o perfil da mortalidade por AIDS em idosos, no sentido de se adotar ações educativas e preventivas, além da capacitação profissional para o cuidado desses pacientes. Objetivo: Descrever o perfil epidemiológico de idosos que morreram por AIDS no Distrito Federal (DF) no período de 2007 a 2016. Métodos: Estudo descritivo, do tipo ecológico, com base em dados secundários do Sistema de Informação sobre Mortalidade, obtidos por meio da Gerência de Informação e Análise de Situação em Saúde da Secretaria de Saúde do DF. A análise foi realizada no Statistical Package for the Social Sciences (SPSS). Resultados: Os óbitos foram predominantes em homens (74,1%), especialmente entre 60 e 69 anos (70,4%). A razão por sexo foi de 2,85. Os de ensino fundamental (42,0%), casados/união estável (43,0%) e de raça/cor branca (52%) foram a maioria. Quanto ao local de residência, o Plano Piloto apresentou maior ocorrência (45,7%), seguido de Ceilândia (12,3%) e Taguatinga (8,6%). Conclusão: Observou-se que a AIDS, entre os idosos, segue a tendência nacional, predominância em idosos jovens do sexo masculino, demonstrando que as ações de prevenção necessitam obter maior alcance nessa população. As barreiras relacionadas ao preconceito e ao estigma da doença, tanto dos idosos quanto dos profissionais de saúde, precisam ser melhor estudadas no sentido de superá-las para aumentar a sobrevida e a qualidade de vida desses pacientes.

Abstract Objective To evaluate the development of a safety culture in the organ donation and transplantation process as it is available in the scientific literature. Methods An integrative literature review was conducted in the CINAHL, LILACS, PubMed, Scopus, and Web of Science databases, and the electronic library, SciELO, from 2012 to 2016, using a syntax of keywords and descriptors for each database; fourteen articles were selected for analysis. Results One thousand six hundred and fifty nine studies were found, 33 complete articles were read, and 14 studies were selected for analysis. The information obtained was analyzed critically and grouped into two categories. Category 1 - patient safety culture for the use of medications in the post-transplant period: the involvement of the multidisciplinary team is essential in the orientation process for hospital discharge, and the main factors related to errors in the use of medicines. Category 2 - safety culture in the transplant units: issues related to patient safety of those undergoing transplantation in the pre- and intra-operative periods. Conclusion This study showed that the issue of a culture of safety in the donation and organ transplantation process is incipient in the literature; well-designed studies related to the culture of patient safety are necessary for all the stages of the donation and transplant process.
