In silico evaluation of the gene expression profile of syndecan-4 in different breast tumor subtypes

Introduction: Breast cancer is one of the main causes of death in women. Luminal tumors A and B show good response with hormonal treatments, tumors that overexpress HER-2 can be treated with monoclonal antibodies, whereas triple negative tumors have few treatments available because they present low or absent expression of hormone receptors and HER-2, in addition, they present worse tumor progression. Syndecans are heparan sulfate proteoglycans that have the function of interacting with growth factors, cytokines, and extracellular matrix, thus modulating important processes in tumor progression. Objective: Analyze the expression of syndecan-4 in different subtypes of breast tumors. Methods: Bioinformatics is a useful tool for the study of new biomarkers. In the present study, the TCGA database (514 patients) and Metabric (1,898 patients) were analyzed using the cBioportal software. Gene expression data were analyzed by RNA-Seq and Microarray from biopsies of breast tumors. Results: An alteration in syndecan-4 gene expression was observed among the different subtypes of breast tumors. Patients with a triple-negative tumor had decreased expression for syndecan-4 in both databases. Conclusion: Syndecan-4 is a potential biomarker for breast tumor prognosis since decreased expression of syndecan-4 is related to triple-negative breast cancer.

Comparison between inhalational anesthetics in terms of DNA damage and immunological markers.

This study compared genetic damage and immunological markers between surgical patients who underwent inhalational anesthesia with isoflurane or sevoflurane. Blood samples were collected from surgical patients (n = 18 in the isoflurane group and n = 17 in the sevoflurane group) at baseline (before the anesthesia procedure) and the day after anesthesia. DNA damage was detected using an alkaline comet assay; proinflammatory interleukin (IL)-6 was detected by flow cytometry, and white blood cells were detected via an automatic hematology analyzer. The characteristics of both groups were similar, and neither of the two anesthetics induced DNA damage. Similarly, mild neutrophilia was observed after anesthesia in both groups. Increased IL-6 levels were observed 1 day after anesthesia regardless of the type of anesthetic, but this increase was greater in the isoflurane group. Our study suggested that isoflurane and sevoflurane administration may contribute to changes in the immune parameters measured, though no genotoxic hazard was identified, in healthy adult patients who undergo low-stress surgery.

Evolution of adolescents' dietary patterns in Northeast Brazil from 2008 to 2018.

OBJECTIVE: To evaluate the evolution of the dietary patterns of adolescents in the northeast region of Brazil. METHODS: Secondary analysis of data from the Pesquisa de Orçamentos Familiares (POF - Household Budget Surveys), collected by the Brazilian Institute of Geography and Statistics (IBGE) in the years 2008-2009 and 2017-2018. A total of 3,095 adolescents were evaluated in 2008-2009 and 3,015 in 2017-2018. Food consumption was assessed using two dietary records in 2008-2009 and two 24-hour recalls in 2017-2018, applied on non-consecutive days. Based on these data, principal components factor analysis (PCFA) was performed, followed by orthogonal rotation of the varimax type, to derive dietary patterns, stratified by sex. The results were described as means or percentage frequencies, with their respective 95% confidence intervals. RESULTS: Three main dietary patterns were identified among adolescents from the northeast region of Brazil. Among boys, in 2008-2009, the patterns were called snacks, traditional Brazilian, and coffee; and in 2017-2018, traditional Brazilian, snacks, and mixed, in this order of representativeness of the group's eating habits. Among female adolescents, in 2008-2009, the patterns were snacks, traditional Brazilian, and coffee; and in 2017-2018, traditional Brazilian, snacks, and processed meats. CONCLUSION: The dietary patterns identified in 2008-2009 and 2017-2018 were similar in both genders; however, the snacks pattern, which explained most of the data variability in 2008-2009, was replaced by the traditional Brazilian.

Modulation of gene expression and influence of gene polymorphisms related to genotoxicity and redox status on occupational exposure to inhaled anesthetics.

The extensive use of inhalational anesthetics contributes to both indoor and outdoor (environmental) pollution. The influence of genetic susceptibility on DNA damage and oxidative stress and the possible modulation of gene expression have not yet been investigated upon occupational exposure to waste anesthetic gases (WAGs). This study assessed 8-oxoguanine DNA glycosylase 1 (OGG1) and superoxide dismutase 2 (SOD2) gene expression, which are related to oxidized DNA repair and antioxidant capacity, respectively, and the influence of their polymorphisms (OGG1 rs1052133 and SOD2 rs4880) in 100 professionals highly exposed to WAGs and 93 unexposed volunteers (control group). Additionally, X-ray repair cross complementing 1 (XRCC1 rs25487 and rs1799782) and ataxia telangiectasia mutated (ATM rs600931) gene polymorphisms as well as genetic instability (micronucleus-MN and nuclear bud-NBUD) and oxidative stress (malondialdehyde-MDA and ferric reducing antioxidant power-FRAP) biomarkers were assessed in the groups (control and exposed) and in the subgroups of the exposed group according to job occupation (anesthesiologists versus surgeons/technicians). Except for the ATM TT controls (associated with increased FRAP), there were no influences of OGG1, XRCC1, ATM, and SOD2 polymorphisms on MN, NBUD, MDA, and FRAP values in exposed or control subjects. No significant difference in the expression of either gene evaluated (OGG1 and SOD2) was found between the exposed and control groups. Increased OGG1 expression was observed among OGG1 -/Cys individuals only in the control group. Among the exposed group, anesthesiologists had a greater duration of WAG exposure (both h/week and years) than surgeons/technicians, which was associated with increased MDA and decreased antioxidant capacity (FRAP) and SOD2 expression (redox status). Higher expression of OGG1 was found in -/Cys surgeons/technicians than in anesthesiologists with the same genotype. Increased antioxidant capacity was noted in the surgeons/technicians carrying the ATM T allele and in those carrying XRCC1 -/Gln. Increased MN was influenced by OGG1 -/Cys in surgeons/technicians. Anesthesiologists with ATM CC exhibited increased MN, and those carrying the C allele (CC/CT genotype) exhibited increased NBUD. SOD2 polymorphism did not seem to be relevant for WAG exposure. These findings contribute to advancing the knowledge on genetic susceptibility/gene expression/genetic instability/oxidative stress, including differences in job occupation considering the workload, in response to occupational exposure to WAGs.

Epigenetic programming for obesity and noncommunicable disease: From womb to tomb.

Several epidemiological, clinical and experimental studies in recent decades have shown the relationship between exposure to stressors during development and health outcomes later in life. The characterization of these susceptible phases, such as preconception, gestation, lactation and adolescence, and the understanding of factors that influence the risk of an adult individual for developing obesity, metabolic and cardiovascular diseases, is the focus of the DOHaD (Developmental Origins of Health and Disease) research line. In this sense, advancements in molecular biology techniques have contributed significantly to the understanding of the mechanisms underlying the observed phenotypes, their morphological and physiological alterations, having as a main driving factor the epigenetic modifications and their consequent modulation of gene expression. The present narrative review aimed to characterize the different susceptible phases of development and associated epigenetic modifications, and their implication in the development of non-communicable diseases. Additionally, we provide useful insights into interventions during development to counteract or prevent long-term programming for disease susceptibility.

Evolution of adolescents' dietary patterns in Northeast Brazil from 2008 to 2018

Higher atherogenic risk in schoolchildren is associated with MTMR9 rs2293855 gene polymorphism and genetic score.

Childhood dyslipidaemia is associated with the occurrence of cardiovascular diseases in adulthood, so evaluating whether an individual has a genetic predisposition to this pathology is of great importance for early action of prevention and treatment. This study aimed to evaluate the association between the FTO (rs9939609), MC4R (rs17782313) and MTMR9 (rs2293855) polymorphisms, the obesity-related genetic risk score and atherogenic risk in Brazilian children. This is a cross-sectional study conducted in 544 children aged 4-9 years in the city of Viçosa, Minas Gerais state, Brazil. The single nucleotide polymorphisms rs9939609, rs17782313 and rs2293855, were identified by the system TaqMan SNP genotyping and the obesity-related genetic risk score was determined. The lipid profile (serum total cholesterol [TC], high density lipoprotein [HDL] cholesterol, low density lipoprotein [LDL] cholesterol, triglycerides) was analysed and the atherogenic indices (Castelli I and II indices), atherogenic coefficient (AC), lipoprotein combined index (LCI) and plasma atherogenic index (PAI) were calculated. A semi-structured questionnaire was applied, obtaining data on the sociodemographic, economic and lifestyle characteristics of the children. Weight and height measurements were performed in all children, and body composition was evaluated by Dual-Energy X-ray Absorptiometry (DXA). 55.5% of the sample had dyslipidaemia, while 28.5% of the sample had at least one polymorphism and 2.2% had three polymorphisms. Children with the AG/AA genotypes in the rs2293855 polymorphism had lower HDL cholesterol levels and higher TC/HDL cholesterol, LDL/HDL cholesterol ratios and AC. Those with one or more polymorphisms (rs9939609, rs17782313 and rs2293855) in the genetic risk score had lower HDL cholesterol levels and higher TC/HDL cholesterol ratios, AC, LCI and PAI. In conclusion, the risk allele of the rs2293855 polymorphism and a higher obesity-related genetic risk score were positively associated with higher atherogenic risk in Brazilian children.

Methods: Cross-sectional study with 52 patients hospitalized for COVID-19 at Hospital Santa Casa de Misericórdia in Vitória, Espírito Santo. Information was collected at discharge regarding the sociodemographic, clinical, hospitalization and physical function profile, through a semi-structured questionnaire, electronic medical record, scales and tests. The Modified Medical Research Council (mMRC) was used to grade dyspnea, the Medical Research Council (MRC) was used to assess peripheral muscle strength, manovacuometry, through maximal inspiratory and expiratory pressures, to measure respiratory muscle strength and the Independence Measure Functional (MIF) for functionality. The outcome variable, exercise tolerance, was measured by the 1-minute Sit and Stand Test. Results: All participants presented exercise intolerance at discharge. Performance in the 1-minute Sit and Stand Test was inversely correlated with the degree of dyspnea and directly with inspiratory muscle strength, total score on the Independence Measure Functional, self-care domains, locomotion, mobility and sphincter control. Conclusion: The prevalence of exercise intolerance at discharge due to COVID-19 was 100%, and was correlated with the degree of dyspnea, inspiratory muscle strength and functionality for self-care, locomotion, mobility and sphincter control. The assessment of exercise tolerance stands out as an important predictor of sequelae after COVID-19, capable of assessing the interaction between different

Higher serum uric acid is associated with body fat, retinol-binding protein 4, and antioxidative status in Brazilian children.

OBJECTIVE: The aim of this study was to evaluate the association of serum uric acid (SUA) with adiposity, adipokines, and anti- and oxidative markers in Brazilian children. METHODS: This was a cross-sectional investigation with 378 children ages 8 to 9 y in Viçosa, Minas Gerais, Brazil. Information on sociodemographic and lifestyle characteristics was obtained via questionnaires, and body fat was determined by dual energy x-ray absorptiometry. We compared the distributions of adiposity (total and central), adipokines (adiponectin, chemerin, leptin, and retinol-binding protein 4 [RBP4]), anti- and oxidative markers (plasma ferric reducing antioxidant power [FRAP], superoxide dismutase [SOD], and malondialdehyde [MDA]) by SUA categories using linear regression. RESULTS: SUA was positively associated with total and central fat. Every standard deviation (SD) of SUA was related, respectively, to a 3.4 (95% confidence interval [CI], 2.4-4.4), 4 (95% CI, 2.8-5.1), 4.2 (95% CI, 2.9-5.5), and 3.5 (95% CI, 2.4-4.6) units higher of total, truncal, android, and gynoid fat. We found a positive association of SUA with RBP4 and FRAP, and a negative association with MDA. Every SD of SUA was related, respectively, to 0.1 (95% CI, 0.01-0.1) and 7.8 (95% CI, 5.5-10.1) units higher of RBP4 and FRAP; and to -0.3 (95% CI, -0.5 to -0.1) units lower of MDA. CONCLUSIONS: SUA was positively associated with adiposity, RBP4, and antioxidative status in Brazilian children.

High anesthetic exposure leads to oxidative damage and gene expression changes in physicians during medical residency: a cohort study.

Evaluation of the possible toxic effects of occupational exposure to anesthetics is of great importance, and the literature is limited in assessing the possible association between occupational exposure to anesthetics and oxidative stress and genetic damage. To contribute to the gap of knowledge in relation to cause-effect, this cohort study was the first to monitor exposure assessment and to evaluate oxidative stress, DNA damage, and gene expression (OGG1, NRF2, HO-1, and TP53) in young adult physicians occupationally exposed to the most modern halogenated anesthetics (currently the commonly used inhalational anesthetics worldwide) in addition to nitrous oxide gas during the medical residency period. Therefore, the physicians were evaluated before the beginning of the medical residency (before the exposure to anesthetics-baseline), during (1 1/2 year) and at the end (2 1/2 years) of the medical residency. Anesthetic air monitoring was performed in operating rooms without adequate ventilation/scavenging systems, and biological samples were analyzed for lipid peroxidation, protein carbonyl content, primary and oxidative DNA damage, antioxidant enzymes and plasma antioxidant capacity, and expression of some key genes. The results showed induction of lipid peroxidation, DNA damage, glutathione peroxidase activity, and NRF2 and OGG1 expression up to the end of medical residency. Plasma antioxidant capacity progressively increased throughout medical residency; oxidative DNA damage levels started to increase during medical residency and were higher at the end of residency than at baseline. Protein carbonyls increased during but not at the end of medical residency compared to baseline. The antioxidant enzyme superoxide dismutase activity remained lower than baseline during and at the end of medical residency, and HO-1 (related to antioxidant defense) expression was downregulated at the end of medical residency. Additionally, anesthetic concentrations were above international recommendations. In conclusion, high concentrations of anesthetic in the workplace induce oxidative stress, gene expression modulation, and genotoxicity in physicians during their specialization period.

Associations of adiposity and adipokine concentrations with anti- and oxidative markers in Brazilian children.

OBJECTIVE: The aim of this study was to evaluate the association of body fat, anti- and inflammatory adipokines with anti- and oxidative markers. METHODS: We conducted a cross-sectional study with 378 schoolchildren ages 8 to 9 y in Viçosa, Minas Gerais, Brazil. We obtained information on sociodemographic and lifestyle characteristics via questionnaires, measured height and weight, and estimated body fat by dual energy x-ray absorptiometry. Blood sample was collected to analyze the adipokines (adiponectin, leptin, chemerin, and retinol-binding protein 4) by enzyme-linked immunosorbent assay based on the sandwich principle; and anti- and oxidant markers (plasma ferric reducing antioxidant power [FRAP], superoxide dismutase [SOD], and malondialdehyde [MDA]) by enzymatic methods. Concentrations of anti- and oxidant markers were compared by percent body fat quartiles and adipokine concentrations terciles using of linear regression adjusted for potential confounders. RESULTS: Total and central body fat were positively associated with FRAP. Every 1 standard deviation (SD) of total fat was associated with 4.8 higher FRAP (95% confidence interval [CI], 2.7-7). Additionally, every 1 SD of truncal, android, and gynoid fat were associated with, respectively, 5, 4.6, and 4.6 higher FRAP (95% CI, 2.9-7.1; 2.6-6.7; and 2.4-6.8, respectively). However, adiponectin was inversely associated with FRAP; every adiponectin SD was related to -2.2 lower FRAP (95% CI, -3.9 to -0.5). Chemerin was positively associated with SOD [5.4 (95% CI, 1.9-8.8) SOD units per chemerin SD]. CONCLUSIONS: The body fat measures and adiposity-related inflammation (chemerin) were positively associated with antioxidative markers in children, whereas the adiponectin (anti-inflammatory marker) was inversely associated with FRAP (antioxidative marker).

Modulation of gene expression and inflammation but not DNA damage after sevoflurane anesthesia.

This study assessed, for the first time, the expression of the genes hOGG1, TP53, and IL-6 in leukocytes by real-time quantitative polymerase chain reaction in surgical patients before (baseline), during (2 h of anesthesia) and 1 day after sevoflurane anesthesia. Additionally, DNA damage was detected by the comet assay, serum interleukin (IL)-6 was detected by flow cytometry, and differential leukocyte counting was also performed. TP53 and hOGG1 expression was downregulated on the day after anesthesia compared to before anesthesia. However, IL-6 expression did not change, and no DNA damage induction was observed during or after anesthesia. At the systemic level, mild neutrophilia and an increase in IL-6 levels occurred after anesthesia. Our findings suggest that sevoflurane anesthesia downregulates gene expression (hOGG1 and TP53) and contributes to an inflammatory status (increased systemic IL-6 and mild neutrophilia) but is not associated with DNA damage in patients without comorbidities who undergo minor elective surgery.

Development of Immobilized Carreira (Phosphoramidite, Olefin) Ligands and Application in Iridium-Catalyzed Asymmetric Allylic Amination.

A family of polystyrene-supported (phosphoramidite, olefin) ligands L1-L4, based on the original design by Defieber and Carreira, has been developed and applied in iridium-catalyzed asymmetric allylic amination of unmasked allylic alcohols (27 examples, up to 99% ee). Among them, functional resins L1 and L4 exhibit important advantages such as easy preparation, ligand recyclability, and easy handling for sequential use. As a distinctive advantage, the catalytic use of the iridium complexes of L1 and L4 allows the straightforward reuse of a high percentage of the expensive iridium metal involved in the complexes, which is not achievable under homogeneous conditions with the corresponding monomeric complexes.

Evaluation of genetic instability, oxidative stress, and metabolism-related gene polymorphisms in workers exposed to waste anesthetic gases.

Professionals who work in operating rooms (ORs) may be exposed daily to waste anesthetic gases (WAGs) due to the use of inhalational anesthetics. Considering the controversial findings related to genetic damage and redox status in addition to a lack of knowledge about the effect of polymorphisms in genes related to phase I and II detoxification upon occupational exposure to WAGs, this cross-sectional study is the first to jointly evaluate biomarkers of genetic instability, oxidative stress, and susceptibility genes in professionals occupationally exposed to high trace amounts of halogenated (≥ 7 ppm) and nitrous oxide (165 ppm) anesthetics in ORs and in individuals not exposed to WAGs (control group). Elevated rates of buccal micronucleus (MN) and nuclear bud (NBUD) were observed in the exposure group and in professionals exposed aged more than 30 years. Exposed males showed a higher antioxidant capacity, as determined by the ferric reducing antioxidant power (FRAP), than exposed females; exposed females had higher frequencies of MN and NBUD than nonexposed females. Genetic instability (MN) was observed in professionals with greater weekly WAG exposure, and those exposed for longer durations (years) exhibited oxidative stress (increased lipid peroxidation and decreased FRAP). Polymorphisms in metabolic genes (cytochrome P450 2E1 (CYP2E1) and glutathione S-transferases (GSTs)) did not exert an effect, except for the effects of the GSTP1 (rs1695) AG/GG polymorphism on FRAP (both groups) and GSTP1 AG/GG and GSTT1 null polymorphisms, which were associated with greater FRAP values in exposed males. Minimizing WAG exposure is necessary to reduce impacts on healthcare workers.

Estatuto do Idoso: análise dos fatores associados ao seu conhecimento pela população idosa brasileira / Statute of the Elderly: analysis of the factors associated with awareness of the statute among the elderly Brazilian population

Resumo O objetivo deste artigo é analisar os fatores associados ao conhecimento do Estatuto do Idoso pela população brasileira não institucionalizada com 60 anos ou mais. Trata-se de um estudo transversal e exploratório, que utilizou dados do Estudo Longitudinal de Saúde dos Idosos Brasileiros (ELSI-Brasil) realizado nos anos de 2015 e 2016. A análise estatística foi feita por meio do teste qui-quadrado e emprego de modelos logísticos binários. Maiores chances de conhecer o Estatuto do Idoso entre os mais escolarizados (OR: 3,17; IC95%: 2,19-4,60), aqueles pertencentes ao quartil mais alto de riqueza (OR: 2,96; IC95%: 2,00-4,38) e entre os que sofreram discriminação em função da idade (OR: 1,73; IC95%: 1,39-2,16). Em contrapartida, ter 80 anos ou mais (OR: 0,59; IC95%: 0,43-0,82) e menor comunicação com os filhos (OR: 0,56; IC95%: 0,43-0,74) está associado a um menor conhecimento dessa legislação. Muitas desigualdades no conhecimento dessa legislação, em especial as socioeconômicas, foram observadas demonstrando que o conhecimento dos direitos estabelecidos não é homogêneo. O entendimento de toda a população quanto às prerrogativas do Estatuto do Idoso é essencial para avanços quanto a sua aplicabilidade e efetividade.

Abstract The scope of this article is to analyze the factors associated with awareness of the Statute of the Elderly by the non-institutionalized Brazilian population aged 60 years and older. It involves a cross-sectional and exploratory study, which used data from the Longitudinal Study of Health of Elderly Brazilians (ELSI-Brasil) conducted in 2015 and 2016. Statistical analysis was assessed by means of the chi-square test and with the use of binary logistic models. Awareness of the Statute of the Elderly was higher among the better educated elderly group (OR: 3.17; 95%CI: 2.19-4.60), those belonging to the highest quartile of the wealth index (OR: 2.96; 95%CI: 2.00-4.38), and among those who suffered discrimination based on age (OR: 1.73; 95%CI: 1.39-2.16). On the other hand, being 80 years old or older (OR: 0.59; 95%CI: 0.43-0.82) and having less communication with their children (OR: 0.56; 95%CI: 0.43-0.74) is associated with lesser awareness of this legislation. Many inequalities in awareness of the legislation, especially socioeconomic inequalities, were observed, revealing that awareness of established rights is not homogeneous. Awareness of the entire population regarding the prerogatives of the Statute of the Elderly is essential for advances in its applicability and effectiveness.

O objetivo deste artigo é analisar os fatores associados ao conhecimento do Estatuto do Idoso pela população brasileira não institucionalizada com 60 anos ou mais. Trata-se de um estudo transversal e exploratório, que utilizou dados do Estudo Longitudinal de Saúde dos Idosos Brasileiros (ELSI-Brasil) realizado nos anos de 2015 e 2016. A análise estatística foi feita por meio do teste qui-quadrado e emprego de modelos logísticos binários. Maiores chances de conhecer o Estatuto do Idoso entre os mais escolarizados (OR: 3,17; IC95%: 2,19-4,60), aqueles pertencentes ao quartil mais alto de riqueza (OR: 2,96; IC95%: 2,00-4,38) e entre os que sofreram discriminação em função da idade (OR: 1,73; IC95%: 1,39-2,16). Em contrapartida, ter 80 anos ou mais (OR: 0,59; IC95%: 0,43-0,82) e menor comunicação com os filhos (OR: 0,56; IC95%: 0,43-0,74) está associado a um menor conhecimento dessa legislação. Muitas desigualdades no conhecimento dessa legislação, em especial as socioeconômicas, foram observadas demonstrando que o conhecimento dos direitos estabelecidos não é homogêneo. O entendimento de toda a população quanto às prerrogativas do Estatuto do Idoso é essencial para avanços quanto a sua aplicabilidade e efetividade.
