Objetivo: Avaliar a nutrição de pacientes cirúrgicos com neoplasia no trato gastrointestinal em uso de suplemento alimentar. Método: Trata-se de uma revisão sistemática de literatura realizada nas bases de dados Google Scholar, PubMed, Scielo e Web of Science, no período de maio a junho de 2021, sem recorte temporal ou restrição de idioma, através dos descritores: “enteral nutrition e immunenutrition”, “cancerpatients e gastriccancerpatients”, “preoperative, perioperative e postoperative”. Resultados: Foram selecionados 8 estudos, destes, a maioria identificou benefícios na utilização da suplementação em razão da diminuição de células TNF-a, do cortisol e da transferrina, diminuindo o tempo de internação e melhora no estado funcional dos participantes suplementados. Conclusão: Os achados foram positivos, no entanto, houve algumas limitações como a heterogeneidade em abordagens terapêuticas e perda de pacientes durante o estudo, apesar de apresentarem baixo risco de viés, ainda há a necessidade de mais estudos.

The present study used evidence-based dentistry (EBD) to identify clinical studies that described the effects of alcohol on fetal craniofacial development and qualitatively analyze the results found via this systematic review. This systematic review followed the guidelines “Meta-analysis Of Observational Studies in Epidemiology” (MOOSE). As a research strategy, several medical and scientific platforms were chosen, in which studies were sought using keywords defined from medical subject headings (MeSH), following the criterion of choosing keywords that were most related to the proposed theme. A total of 278 studies (116 studies in humans and 162 studies in animals) were identified and, after screening and analysis based on the inclusion criteria, twenty-six observational studies in humans were chosen for the configuration of this systematic review. Studies have reported fetal alterations related to alcohol consumption by mothers such as in the head shape and size, thin upper lip, hypoplastic philtrumbone, short palpebral fissures, micrognathia, flat nasal bridge, among others. These were more often found in patients whose mothers were alcoholics or those who had ingested high doses of alcohol, especially during the first trimester of gestation. Based on the analysis of the results, the impact of maternal alcohol consumption on fetal craniofacial development was evidenced and, as such, these complications can be harmful to the quality of life of the patient, both in childhood and in adulthood, as well as leading to lifelong sequelae. The results also suggest that to avoid craniofacial anatomical abnormalities related to alcohol, the best course of action is to stop alcohol consumption completely or at least reduce it to a minimum level before conception.

Introduction: Inflammatory Bowel Disease (IBD), periodontitis and Systemic Lupus Erythematous (SLE) are multifactorial diseases, one of the factors in the course of these diseases is the rs333 polymorphism in the CC chemokine receptor type five (CCR5) gene. However, the results remain contradictory. Therefore, we aimed to perform a meta-analysis evaluating the relation between this polymorphism and the aforementioned conditions. Material and Methods: A search in the literature was performed in diverse scientific and medical databases for studies published before June 22, 2020. The data were extracted from the studies and the statistical evaluation was performed by the calculations of statistical heterogeneity (I²), Odds Ratio (OR) with 95% of Confidence Intervals (CI) and publication bias. The values of P

This study aimed to examine and recognize the impacts of antinoplastic chemotherapeutics on the development of dental germ, employing a systematic review. A retrieving in the literature was carried out, using several medical and scientifical databases (ClinicalKey, Cochrane Library, Google Scholar, MedLine, PubMed, and ScienceDirect), by two investigators separately. In the end of this systematic search, eight articles met the required criteria for inclusion and, therefore, composed the results. Among these, four articles are about observational studies in humans, and the other four about experimental animal studies. In both cases and species, anomalies such as microdontia, hypodontia/agenesia, and root shortening were observed. The severity and frequency varied according to the nature of the chemotherapeutics applied as well as the administered dosage and the patient's age at the time of first exposure. Through the results, it was possible to show the direct impacts of chemotherapy on the odontogenesis process as well as factors such as the type of chemotherapy, the age of the individual at the time of first exposure and the dosage used. All of those should be taken into account when choosing a therapeutic protocol for an oncology patient. Besides, we observed the need for more studies in this area and that these should be standardized in order to allow an objective and direct analysis of comparable parameters, even when different approaches are used.

Sulfated polysaccharides (PLS) extracted from the marine algae of the genus Gracilaria showed biological activity in different inflammatory models, except for periodontitis. Thus, this study aimed to evaluate the effectiveness of the treatment with PLS from Gracilaria caudata in ligature-induced periodontitis. 40 animals distributed into 5 groups were used (the control group (unligated), the ligated untreated group, and the ligated groups treated with 2.5, 5.0 and 10.0 mg/kg of PLS with intraperitoneal injection, respectively). After 20 days of treatment, the animals were killed and the following parameters were evaluated: Gingival Bleeding Index (GBI), Probing Pocket Depth (PPD), Myeloperoxidase (MPO) activity, Alveolar Bone Loss (ABL) for periodontal tissues; histopathological examination of gingival and liver tissues (Steatosis score); glutathione and malondialdehyde concentrations in the liver, serum levels of alanine aminotransferase and aspartate aminotransferase. The data revealed that treatment with 2.5 mg/kg of PLS showed the best anti-inflammatory effects with reduction of GBI, PPD and MPO activity, as well as oxidative stress and steatosis in liver. Our results indicated that the adjunct treatment with PLS from Gracilaria caudata could prevent the periodontal and hepatic tissue alteration caused by periodontitis.

Dengue fever is a clinical manifestation of dengue virus (DENV) infection well defined by the intense host immune response with the development of high fever, anorexia, headache and muscle pain. Several immune mediators are involved in the pathophysiology of DENV infection, in which polymorphisms in immune molecule genes contribute with the susceptibility and severity of the infection. Several meta-analyses are available with significant findings in the association between genetic variants in immune-mediator genes and dengue, though the results may be false positive. Hence, to solve this issue, we have performed a systematic revaluation with Bayesian approaches to verify the false positive rate in these results. A systematic search was performed for meta-analytic studies on the aforementioned issue. The calculations of false positive report probability (FPRP) and the Bayesian false-discovery probability (BFDP) at the prior probability of 10

Resultados: A administração de GBP foi eficaz na redução das lesões macro e microscópicas, diminuindo significativamente o peso úmido do cólon de camundongos com colite. A droga reduziu a concentração de mieloperoxidase (MPO), malondialdeído (MDA) e interleucina 1 (IL-1) e aumentou o nível de glutationa (GSH) em camundongos com colite em comparação com camundongos normais. O tratamento com antagonistas dos receptores endocanabinóides (ECs) não alterou o efeito do GBP. Conclusão: A gabapentina foi capaz de reduzir os parâmetros inflamatórios na colite induzida por ácido acético, mas seu efeito parece ser independente da via canabinóide.

Latex proteins extracted from Plumeria pudica (LPPp) have anti-inflammatory activity in different experimental models. Considering this relevant result, we evaluated the toxicological aspects of the treatment of mice with LPPp. Acute and subchronic toxicities were determined by daily intraperitoneal administration of 40 mg/kg of LPPp for 10 or 20 days, respectively, and were followed by behavioral, hematological, biochemical and histopathological evaluation. Results showed no significant changes in body weight and organs of animals treated with LPPp. Total and differential blood leukocyte counts of LPPp groups did not differ from controls. There was no significant difference in aspartate aminotransferase, alanine aminotransferase, creatinine and urea measurements for the group treated for 20 days. The level of glutathione in the kidney was significantly higher in animals treated with LPPp in the acute toxicity test, but no differences were observed for the subchronic evaluation. The concentration of malondialdehyde and myeloperoxidase activity in the organs did not differ from controls. Histopathological examination of kidney, spleen and liver tissue of animals treated with LPPp revealed normal structures or reversible alterations. Intraperitoneal LD50 of LPPp was higher than 2,000 mg/kg. The data obtained reveal that LPPp is nontoxic at 40 mg/kg. Las proteínas extraídas del látex de Plumeria pudica (LPPp) tienen actividad antiinflamatoria en diferentes modelos experimentales. Ante este relevante resultado, evaluamos los aspectos toxicológicos del tratamiento de ratones con LPPp. La toxicidad aguda y subcrónica se determinó mediante la administración intraperitoneal diaria de 40 mg/kg de LPPp durante 10 o 20 días, respectivamente, y fueron seguidas por evaluación conductual, hematológica, bioquímica e histopatológica.

Periodontitis is a high prevalent disease into the clinical dentistry. Genetic variations in interleukins (IL) genes were associated with chronic periodontitis (CP) and were focus of several meta-analyses. This study aimed to assess the noteworthiness in the meta-analyses by means of a Bayesian approach to determinate possible false report associations. A systematic search was performed for meta-analyses with associations between gene polymorphisms in interleukins and CP. The calculations for the False-Positive Rate Probability (FPRP) and the Bayesian False Discovery Probability (BFDP) were performed to assess the noteworthiness with a statistical power of 1.2 and 1.5 of Odds Ratio at a prior probability of 10-3 and 10-6. As results, eight meta-analyses approaching the IL1A/rs1800587, IL1B/rs1143634, IL1RN/rs2234663, IL4/rs2243250, IL6/rs1800795/rs1800796, IL17A/rs2275913 and IL18/rs1946518/rs187238 polymorphisms have been identified. Twenty-two from 270 calculations (8.15%) were noteworthy. Herein, we have identified the IL1A and IL1B polymorphisms as noteworthy biomarkers for CP susceptibility.

Background and objective Periodontitis may crosstalk with renal diseases, yet that remains unclear. We investigated whether the renal alterations caused by induced periodontitis are reversible after removal of the ligatures in experimental ligature-induced periodontitis. Material and methods Twenty-four female rats were divided into three groups: control (without periodontitis), periodontitis (20 days of ligature-induced periodontitis), and P20-20 (20 days of ligature-induced periodontitis and 20 days after ligature removal). The following periodontal parameters were assessed: gingival bleeding index, probing pocket depth, myeloperoxidase activity, and alveolar bone height. For renal tissues, histopathology, malonaldehyde (MDA) levels, glutathione (GSH) content, and renal weight were evaluated. In the blood, creatinine, uric acid, albumin, total cholesterol, total protein, and glucose levels were assessed. Total protein and creatinine levels in urine were also investigated. Results Rat renal tissues did not demonstrate reversal of periodontitis-related changes in the P20-20 group in terms of MDA, GSH, and histopathological evaluations when compared to the periodontitis group. Accordingly, only total cholesterol levels were reversible in the P20-20. Conclusion Renal alterations caused by ligature-induced periodontitis persisted even after removal of ligatures in rats.

Several factors are involved in the periodontitis with host response through cytokines and as well as with influence of polymorphisms in cytokine genes, however the results remained contradictory. This study aimed at evaluating the rs1143634 polymorphism in interleukin-1B gene, a cytokine gene, and the risk of chronic periodontitis with conducting a meta-analysis focusing in ethnicity. A review in literature was performed in several databases to studies published before June 2017. Data extraction was performed by two calibrated investigators and the calculations of the meta-analysis were obtained through Review Manager version 5.2 statistical software with Odds Ratio (OR) calculation and Funnel plot (P 0.05) to heterogeneity and the Comprehensive Meta-analysis version 3.3.070 to assessment publication bias by Egger's and Begg's tests. In overall, 54 case/control studies composed the meta-analysis. T allele was significantly associated with patients case (OR = 1.35, 95% CI: 1.24, 1.48, P 0.00001) in the overall analysis. The stratified evaluation showed the rs1143634 polymorphism had significant association with disease in Caucasian, Asian and mixed population was excepted in African ethnicity (P 0.05). No publication bias was found in allelic evaluation. This meta-analysis in 9376 participants with 54 case/control studies revealed the rs1143634 polymorphism was associated with elevated risk of chronic periodontitis in overall analysis as well as Caucasian and Asian ethnicities and Mixed population.

Sulphated polysaccharides extracted from algae have been extensively studied for their diverse biological activities. Thus, the purpose of this study was to evaluate the chemical composition, the anti-diarrhoeal effect and acute toxicity of a sulphated polysaccharide fraction obtained from Gracilaria intermedia (SP-Gi). Initially, the FT-IR of SP-Gi revealed to be an agaran with sulphation at C-6 of the l-galactosyl residues. The anti-diarrhoeal activity of SP-Gi was evaluated in a castor oil-induced diarrhoea model. The effects of SP-Gi on enteropooling, Na +-K +-ATPase activity, gastrointestinal transit, and gastric emptying were then examined. Subsequently, the effect of SP-Gi on diarrhoea induced by cholera toxin (CT) and Escherichia coli was examined. In addition, an acute toxicity test was conducted in accordance with OECD guideline 423. Pre-treatment with SP-Gi reduces the total faeces, total diarrhoeal faeces, and enteropooling. SP-Gi (30mg/kg p.o.) increased Na+/K+-ATPase activity and reduced gastrointestinal transit through anticholinergic mechanisms. ELISA demonstrated that SP-Gi can interact with GM1 receptors and CT. SP-Gi reduced diarrhoea induced by E. coli and prevented weight loss in the animals. Moreover, SP-Gi did not induce any toxicity signs. These results suggest that SP-Gi is a possible candidate for the treatment of diarrhoeal illnesses.

Frutas são alimentos perecíveis, portanto, sua desidratação contribui para o aumento de sua vida útil. A liofilização vem recebendo destaque dentre as operações de secagem, já que os produtos não são submetidos a altas temperaturas. O objetivo do presente trabalho foi modelar a cinética de liofilização de tangerinas e uvas e avaliar sensorialmente as frutas desidratadas. A liofilização foi realizada com frutas congeladas à pressão de 70 Pa e aquecimento a 60 °C por 48 h. Os dados experimentais foram ajustados à lei de Fick e a modelos empíricos/semi empíricos. Foram avaliados sensorialmente cor, sabor, aroma, textura e impressão global dos consumidores com base em uma escala hedônica de nove pontos. A lei de Fick representou satisfatoriamente os dados experimentais de desidratação das frutas. O modelo de Page foi o que melhor representou a liofilização das uvas e o Aproximação da difusão, a das tangerinas. Aproximadamente 65 % das notas atribuídas pelos provadores às frutas desidratadas situaramse entre os termos “gostei ligeiramente” e “gostei muito” para todos os quesitos avaliados. A textura das frutas desidratadas apresentou média superior a 7,0. Os resultados mostraram que há mercado para produtos inovadores, como uvas e tangerinas liofilizadas.

This study aimed to verify noteworthy findings between genetic risk factors and autism spectrum disorder (ASD) by employing the false positive report probability (FPRP) and the Bayesian false-discovery probability (BFDP). PubMed and the Genome-Wide Association Studies (GWAS) catalog were searched from inception to 1 August, 2019. We included meta-analyses on genetic factors of ASD of any study design. Overall, twenty-seven meta-analyses articles from literature searches, and four manually added articles from the GWAS catalog were re-analyzed. This showed that five of 31 comparisons for meta-analyses of observational studies, 40 out of 203 comparisons for the GWAS meta-analyses, and 18 out of 20 comparisons for the GWAS catalog, respectively, had noteworthy estimations under both Bayesian approaches. In this study, we found noteworthy genetic comparisons highly related to an increased risk of ASD. Multiple genetic comparisons were shown to be associated with ASD risk, however, genuine associations should be carefully verified and understood.

BACKGROUND AND OBJECTIVE This study aimed to assess the effectiveness of the treatment with alpha-terpineol (αTPN) complexed with beta-cyclodextrin (βCD) on oral, blood, and hepatic parameters in ligature-induced periodontitis. MATERIAL AND METHODS Forty female rats were distributed among the following groups: control (vehicle solution), periodontitis (ligature + vehicle solution), 5 mg/kg of αTPN-βCD (ligature), and 25 mg/kg of αTPN-βCD (ligature). Compounds were administered daily via intraperitoneal injection over a 20-day period. Periodontitis was induced with the bilateral insertion of ligatures around the first lower molars of each rat. Oral parameters, as well as blood biomarkers, were measured: histopathological assessment of the hepatic tissue was carried out using light and transmission electron microscopy. RESULTS The treatment with αTPN-βCD significantly improved several oral parameters and blood biomarkers in comparison with rats with periodontitis. In addition, the treatment with αTPN-βCD significantly ameliorated the steatosis score and reduced the number of lipid droplets and the amount of foamy cytoplasm in the hepatocytes of rats with periodontitis. CONCLUSION The results obtained suggest that the treatment with αTPN-βCD improves several oral and blood parameters in rats with experimental periodontitis. In addition, hepatic alterations caused by periodontitis were ameliorated in the rats treated with αTPN-βCD.

Periodontitis results from the presence of periodontopathogenic bacterial activity in the region of the gingival sulcus promoting tissue degradation and alveolar bone resorption. Biochemical analysis of the saliva can be used as a less invasive method for disease prognosis. This study aimed to evaluate the relationship between biochemical protein levels in the saliva sample of patients with chronic periodontitis and healthy patients.A literature review was performed using electronic databases (Cochrane Library, Google Scholar, MEDLINE, PubMed, and Web of Science) for studies published before July 2, 2016. The abstracts were evaluated, and the data extraction was performed by two calibrated examiners. The mean difference, and heterogeneity were calculated, and funnel plots were produced.Twenty case-control studies were selected with 2436 patients with chronic periodontitis and 1787 controls. The meta-analysis showed that increased levels of aspartate aminotransferase (AST), alanine aminotransferase (ALT), creatine kinase (CK), lactate dehydrogenase (LDH), alkaline phosphatase (ALP), and acid phosphatase (ACP) were all associated with periodontitis (p 0.05), while blood urea nitrogen (BUN) and osteoprotegerin (OPG) levels did not show statistical differences between cases and controls (p 0.05).This meta-analysis evidenced that increased levels of AST, ALT, CK, gama glutamil transferase (GGT), LDH, ALP, and ACP are associated in patients with chronic periodontitis, while BUN and OPG level in saliva did not present differences between groups.

Background Chronic periodontitis (CP) is an immune-inflammatory disease that promotes tissue damage around the teeth. Among the several inflammatory mediators that orchestrate the periodontitis, there is the interleukin (IL)-2. Genetic variations in IL2 gene may be associated with the risk and severity of the disease. Contrary results are available in the literature with inconclusive findings and none meta-analysis to gather these data. Methods A literature search was performed for studies published before June 11, 2019 in diverse scientific and educational databases. The data was extracted by two investigators and the statistical evaluation was performed by Review Manager statistical program with heterogeneity (I2) and Odds Ratio (OR) with 95% of Confidence Intervals (CI) calculations and a sensitive analysis to assess the accuracy of the obtained results. The publication bias was evaluated by Begg’ and Egger’s test with Comprehensive meta-analysis software. The value of P Results Five studies were identified in diverse ethnical groups with 1425 participants. The − 330 T/G polymorphism in IL2 gene was not significantly associated with CP in allelic evaluation (P > 0.05) as well as in the genotypic comparisons (P = 0.15). The Begg’s test and the linear regression Egger’s test did not show any evidence of publication bias risk (P > 0.05) which was corroborated by the absence of obvious asymmetry in Funnel plot graphic. Conclusions This meta-analysis showed a non-significant association between − 330 T/G polymorphism in IL2 gene and CP in any allelic evaluation.

The association of polymorphisms in genes responsible for immunological mediators with dengue allows the identification of certain genetic alterations that increase or decrease the development risk of the disease. A few number of studies that correlate the interleukin 6–174 G > C (IL6–174 G > C) polymorphism (rs1800795) with dengue. However, there is an inconsistency on the polymorphism influence on the disease which motivated this meta-analysis. So, this study aimed to evaluate the rs1800795 polymorphism with protection or susceptibility for development of dengue. A search of the literature was performed for studies published before 05 September 2020 in various databases. Calculations of Odds Ratio (OR) with 95% of Confidence Intervals (CI) and heterogeneity (I2) were assessed and publication bias was done by Begg’ and Egger's test. The value of P

Objetivo: Desenvolver um modelo de dieta rica em gordura (DRG) que sozinho não resultou em doença hepática gordurosa não alcoólica (DHGNA), permitindo estudar a associação de comorbidades com o modelo de dieta rica em gordura. Material e métodos: Os ratos foram divididos em 2 grupos: dieta padrão e dieta rica em gordura, cada grupo com 8 animais. Os ratos foram submetidos à análise dos seguintes parâmetros no tecido hepático: dosagem de malondialdeído (MDA), glutationa (GSH) e atividade da mieloperoxidase (MPO). As amostras de fígado também foram avaliadas histopatologicamente quanto aos níveis séricos de alanina aminotransferase (ALT), aspartato aminotransferase (AST), albumina (ALB), fosfatase alcalina (FAL), ácido úrico e colesterol total (TC), cálcio (CA), ureia e HDL. Resultados: Mostraram que houve diferença significativa em MDA, GSH, colesterol total (CT), ALT, ALB, ácido úrico (AU), cálcio (CA) e HDL. A avaliação histopatológica apresentou escore baixo, insuficiente para a classificação da DHGNA. Conclusão: Este estudo demonstrou que o modelo de dieta rica em gordura não causou DHGNA. Esse achado permite utilizar a dieta hiperlipídica caracterizada neste estudo para investigar as possíveis alterações hepaticas causadas por outras comorbidades.

The mapping and georeferencing, using Google maps, aim to make the process of territorialization somewhat continuous, favoring the approximation between professionals and the population. Conclusion: Google maps has great potential as a didactic resource, as it proved to be effective in promoting an approximation with the spatial and social reality, contributing to a better understanding of students in the aspects addressed during the process of territorialization in health carried out in primary care.

The aim of this study was to perform a meta-analysis to verify whether MBL-2 gene polymorphisms (rs1800450 and rs1800451) are associated with susceptibility to periodontitis. A search of the literature was performed for studies published before 2, March 2020 in various databases. Calculations of Odds Ratio (OR) with 95% of Confidence Intervals (CI) and heterogeneity (I2) were assessed and publication bias was calculated by Begg’ and Egger's test. The value of P .05). Neither the mutant allele in rs1800450 polymorphisms nor the mutant allele in rs1800451 polymorphisms was associated with periodontitis (OR = 1.11, CI: 0.90–1.38, P = .33; OR = 1.01, CI: 0.75–1.35, P = .96, respectively) with no interference of I2 in these evaluations (I2 = 0%, P = .75 and I2 = 0%, P = .65, respectively) as well as in all calculations. The stratified analyses were composed by Ethnicity in Caucasian and Mixed populations and genotyping methods. In conclusion, this meta-analysis showed a non-significant association among the rs1800450 and 1,800,451 polymorphism in MBL-2 gene and periodontitis in the overall evaluation, Caucasian group and Mixed population.

A number of genome-wide association studies (GWASs) and meta-analyses of genetic variants have been performed in antineutrophil cytoplasmic antibody (ANCA)-associated vasculitis. We reinterpreted previous studies using false-positive report probability (FPRP) and Bayesian false discovery probability (BFDP). This study searched publications in PubMed and Excerpta Medica Database (EMBASE) up to February 2018. Identification of noteworthy associations were analyzed using FPRP and BFDP, and data (i.e., odds ratio (OR), 95% confidence interval (CI), p-value) related to significant associations were separately extracted. Using filtered gene variants, gene ontology (GO) enrichment analysis and protein&ndash, protein interaction (PPI) networks were performed. Overall, 241 articles were identified, and 7 were selected for analysis. Single nucleotide polymorphisms (SNPs) discovered by GWASs were shown to be noteworthy, whereas only 27% of significant results from meta-analyses of observational studies were noteworthy. Eighty-five percent of SNPs with borderline p-values (5.0 &times, 10&minus, 8 &lt, p &lt, 0.05) in GWASs were found to be noteworthy. No overlapping SNPs were found between PR3-ANCA and MPO-ANCA vasculitis. GO analysis revealed immune-related GO terms, including &ldquo, antigen processing and presentation of peptide or polysaccharide antigen via major histocompatibility complex (MHC) class II&rdquo, &ldquo, interferon-gamma-mediated (IFN-&gamma, ) signaling pathway&rdquo, By using FPRP and BFDP, network analysis of noteworthy genetic variants discovered genetic risk factors associated with the IFN-&gamma, pathway as novel mechanisms potentially implicated in the complex pathogenesis of ANCA-associated vasculitis.

Dengue is an acute viral disease whose clinical condition is related to the interaction of factors related to the Dengue virus (DENV), environment and the host, with the immunity of the human host contributing a substantial role in the pathogenesis of DENV infection. Studies have demonstrated that single nucleotide polymorphisms (SNPs) in the promoter regions of cytokine genes such as tumor necrosis factor (TNF-α) affect transcription and/or expression; and therefore, may influence the pathogenesis of infectious diseases, such as dengue. Consequently, the objective of this study was to assess through a case-control study whether there was an association between the presence of SNPs −308G/A and −238G/A in the TNF-α gene and 158 patients with dengue and 123 controls. No association was found between the SNPs and the dengue cases in the study population. We then performed a meta-analysis, retrieving data from case-control studies in the literature for the same polymorphisms. For SNP-308G/A, the GG genotype was associated with dengue fever (DF) risk (OR = 1.24, 1.00–1.53; p = 0.05; I2 = 0%), while the GA genotype (OR = 0.75, 0.60–0.93; p = 0.01; I2 = 0%) and allele A (OR = 0.75, 0.60–0.93; p = 0.01; I2 = 0%) were associated with protection. The genotype GG population in the Asian continent (OR = 1.81 [1.06, 3.09], p = 0.03, I2 = 0%) and American (OR = 1.29 [1.00, 1.65], p = 0.05, I2 = 0%) was also associated with protection in the comparison between the cases versus the control group. In each comparison, the dominant model AA + GA (p

Objective Quantitatively evaluate blood parameters of the erythrocyte lineage in patients with chronic periodontitis and healthy controls by means of a meta-analysis. Material and methods A review of literature was performed in the scientific databases for studies published before September 2016. The abstracts were evaluated and the extraction of data performed by two examiners. The parameters assessed were: hemoglobin levels, number of circulating red blood cells, hematocrit, mean corpuscular hemoglobin and mean corpuscular hemoglobin concentration in patients with chronic periodontitis and healthy controls. The calculations were obtained through the statistical software Review Manager version 5.3, with calculation of Mean Difference, heterogeneity (I²) and funnel plot with P Results Nine case/control studies composed the results with 342 patients with chronic periodontitis and 359 healthy controls. There was a significant decrease in hemoglobin levels (MD = -1.60, 95% CI: -2.72, -0.48, P = 0.005) and number of circulating red blood cells (MD = -0.51, 95% CI: -0.78, -0.24, P = 0.0002), hematocrit (MD = -4.41, IC 95%: -7.13, -1.68, P = 0.002), mean corpuscular hemoglobin (MD = -0.80; IC 95%: -1.38, -0,22, P = 0.007) and mean corpuscular hemoglobin concentration (MD = -0.93, IC 95%: -1.63, -0.23, P = 0.009) in patients with chronic periodontitis when compared to healthy controls. No publication bias was found through the funnel plot asymmetry. Conclusion There is an associated of the reduction of hematological parameters (such as levels of hemoglobin and circulating red blood cells, hematocrit, mean corpuscular hemoglobin and mean corpuscular hemoglobin concentration) to patients with chronic periodontitis.

Background Periodontitis not only causes injury to the periodontium, but also damages other tissues such as: articulate, renal, cardiac, and hepatic. The objective of this study was to investigate periodontitis induced alterations in liver function and structure using an experimental model. Methods Twenty female rats (Rattus norvegicus) were allocated into two groups: control and periodontitis. Gingival bleeding index and oxidative stress parameters and specific circulating biomarkers were measured. Immunohistochemistry was carried out using alkaline phosphatase (AlkP) staining of the liver. Hepatic tissues, cytokines, and lipid contents were measured. Histopathologic evaluation of the liver was carried out using light and electron microscopy. Results Liver histopathologic and immunohistochemistry assessment showed increase in steatosis score, and presence of binucleate hepatocytes and positive cells for AlkP in periodontitis versus control group. Ultrastructural evaluation showed significant increase in size and number of lipid droplets (LD), distance between the cisterns of rough endoplasmic reticulum (RER), mitochondria size, foamy cytoplasm, and glycogen accumulation in the liver of the periodontitis group compared with the control group. In addition, plasma levels of AlkP, high-density lipoprotein (HDL), triglycerides, and total cholesterol were also changed. Conclusion Experimental periodontitis caused immunohistochemistry, histopathologic, ultrastructural, oxidative, and biochemical changes in the liver of rats.

Introduction: Crosswords have been used to complement medical education in a fun way, yet they were not used as a method for the evaluation of students' performance. Objective: The aim of this study was to describe the development of crosswords and verify their validity as a method of performance evaluation in embryology. Materials and Methods: We used crossword based on subjects about stages of embryonic development with different levels of difficulty. To validate the crossword as the evaluation method of teaching, two evaluation methods were applied (the traditional and with crosswords, simultaneously) on students of Federal University of Piaui. The performance of students was analyzed with Pearson's correlation coefficient and data were analyzed to check for normal distribution through the Shapiro-Wilk test with significance level of 0.05. The tests were performed on the BioEstat statistical software version 5.0. Results: As result a total of 28 students were evaluated. It was observed that the resulting score of both the traditional and crossword evaluation methods demonstrating normal distribution (p=0.4127 and p=0.7016, respectively), did not present vices and tendencies. The average scores were 7.1 ± 2.0 and 6.9 ± 1.7 for the traditional and crossword evaluation methods, respectively, showing statistically significant difference (p=0.0001; r=0.67), demonstrating a moderate Pearson's correlation between the methods. Conclusion: In conclusion, crosswords may be used as supplementary material for teaching embryology. Also, crossword functioned as validated and reproducible method of performance evaluation that can be used in as alternative and/or complementary teaching of embryology or other disciplines in the medical ield.

Background Periodontitis is a chronic disease that due to an intense inflammatory response triggers systemic changes such as hepatic alterations. This study aimed to compare hepatic damage in rats that received experimental periodontitis at one or two periodontal sites with ligatures. Material and Methods Eighteen rats were separated into three groups: control, without ligature; periodontitis 1, with one ligature; and periodontitis 2, with two ligatures. The following parameters were assessed: gingival bleeding index, probing pocket depth, tooth mobility, alveolar bone loss, malondialdehyde (MDA) and myeloperoxidase (MPO) activity in periodontal tissue; histopathological evaluation of hepatic tissue (steatosis score); glutathione levels (GSH), MDA, MPO, cholesterol and triglycerides in the liver; and serum levels of alanine aminotransferase (ALT) and aspartate aminotransferase (AST). Results Periodontal evaluation data showed that the periodontitis model worked well. The groups with periodontitis did not differ significantly in relation to MPO activity and MDA levels in the gingival samples, but they were significantly different when compared with the control group. Steatosis was observed in the histological analysis of the groups with periodontitis, but between the periodontitis groups, two ligatures did not cause increase in steatosis score. The levels of GSH, MDA, total cholesterol and triglycerides in the hepatic tissue were not altered between groups with periodontitis, but they showed significant differences in comparison with the control group. The activity of MPO in hepatic tissue and serum levels of AST and ALT did not present significant difference among the three groups. Conclusions In conclusion, our results demonstrated that one or two ligatures inducing periodontitis were both sufficient to cause fatty liver. Steatosis caused by two ligatures did not present larger extension and severity than steatosis caused by one ligature.

Epiisopiloturine (EPI) is an important imidazole alkaloid because of its pharmacological properties. The aim of this study was to investigate the effects of epiisopiloturine on inflammatory parameters of the colonic mucosa in a rat model of Crohn’s disease (CD). For this, we induced colitis using trinitrobenzenosulfonic acid and determined myeloperoxidase (MPO), interleukin 1 β (IL-1β), glutathione (GSH), and malondialdehyde (MDA) levels in the intestinal mucosa. The location and expression of the inflammatory markers in the colon were investigated by immunohistochemistry for NO synthase induced (iNOS), interleukin 1 beta (IL-1β), and cyclooxygenase-2 (COX-2) and western blotting (iNOS and COX-2), respectively. Compared with TNBS alone, epiisopiloturine at 1 mg/kg reduced the macroscopic and microscopic scores, wet weight of the colon, and neutrophilic infiltration and expression of the pro-inflammatory cytokine IL-1β. Epiisopiloturine at 1 mg/kg maintained or restored GSH levels and simultaneously decreased MDA levels. Animals treated with epiisopiloturine exhibited reduced immunostaining for IL-1β, iNOS, and COX-2 and reduced cell count per field. Epiisopiloturine reduced the expression of COX-2 and iNOS in the colon. Based on these findings, we conclude that epiisopiloturine at 1 mg/kg may be an important pharmacological tool against intestinal inflammatory diseases due to its inhibitory action on key enzymes and products involved in inflammation.

This study aimed to investigate the chemical characteristics and the effects of an orabase gel with Cashew Gum Polysaccharide (CG-P) from Anacardium occidentale L. on alveolar bone loss and relative mRNA expression of TNF-α, IL-1β, RANK, RANKL, and OPG in the periodontal tissue of Wistar rats (Rattus norvegicus) subjected to ligature-induced periodontitis. Crude cashew gum was collected and purified by chemical processes; then, the CG-P was mixed with orabase gel. Female rats were randomly divided into four groups of six animals each: saline 0.9% (Sal Group); orabase gel (Gel Group); 50mg CG-P/1g orabase gel (CG-P50 Group) and 150mg CG-P/1g orabase gel (CG-P150 Group). Periodontitis was induced in the animals; they were treated for 20days with one daily topical application. The purification process of CG-P presented high yield and resulted in a protein-free product. The treatment with CG-P150 (150mg CG-P/1g orabase gel) significantly reduced alveolar bone loss, decreased the relative mRNA expression of TNF-α, IL-1β, RANKL and the RANKL/OPG ratio, and caused a significant decrease in myeloperoxidase activity of the gingival tissue. Thus, the CG-P in orabase represents a potential adjuvant drug for the treatment of periodontitis and possible source of new biotechnological discoveries.

Background: Damage caused by periodontitis not only affects periodontal tissues, but also increases the severity of various illnesses such as rheumatoid arthritis, diabetes, and liver diseases. The aim of this study is to investigate the association between induced periodontitis and damage caused through its systemic effects on the liver. Methods: Twenty rats were divided into two groups: control and periodontitis. The following parameters were evaluated: gingival bleeding index (GBI), probing depth (PD), myeloperoxidase (MPO) activity, alveolar bone loss (ABL) for periodontal tissues; histopathologic examination of gingival and liver tissues; immunohistochemistry to cells positive for neural/glial antigen 2 (NG2) expressed in hepatic pericytes, glutathione (GSH), and malondialdehyde (MDA) concentrations in liver; and serum levels of alanine aminotransferase and aspartate aminotransferase. Results: GBI, PD, MPO, ABL, and histopathologic examinations demonstrated the development of periodontitis. There was a significant increase in microvesicular steatosis accompanied by a marked reduction in NG2+ pericytes in the periodontitis group compared with the control group. The periodontitis group had significantly lower GSH and higher MDA concentration in the liver compared with the control group. Conclusions: The present study results link the systemic effects of induced periodontitis with changes in hepatic tissues such as microvesicular steatosis, likely caused by an increase in oxidative stress and lipid peroxidation. The findings from the present study implicate an association between a decrease of pericytes and liver disease caused by ligature-induced periodontitis in rats

Purpose. This work aimed to synthesize the results of recent meta-analysis focusing on polymorphism in inflammatory mediators and its relation with the risk of periodontitis development.Materials and Methods. A systematic search was conducted using databases for publications prior to October 2016. Three examiners extracted data from articles with a clear association between polymorphisms in the inflammatory mediator gene and the development of periodontitis through meta-analysis using the fixed or randomized statistical models to calculate the Odds Ratio with values ofP<0.05considered significant.Results. A total of 13 meta-analysis articles with 25 polymorphisms in seven interleukins (IL-1A, IL-1B, IL-4, IL-6, IL-8, IL-10, and IL-18), three cellular receptors (Fcγreceptors: FCGR2A, FCGR3A, and FCGR3B), and five inflammatory mediators (COX-2, MMP-2, MMP-3, MMP-8, and MMP-9), with a total of 71,531 participants, approaching different classifications of the disease.Conclusion. The study demonstrated that polymorphisms in the IL-1A, IL-1B, IL-6, IL-10, MMP-3 (chronic form), and MMP-9 (chronic form) polymorphisms were significantly associated with the risk of developing periodontitis, whereas other polymorphisms in the IL-4, IL-8, IL-18, Fcγ, COX-2, MMP-2, MMP-3 (aggressive), MMP-8, and MMP-9 (aggressive) polymorphisms had no significant association with risk of developing periodontitis.

Polymorphisms in inflammatory genes such as interleukins 17A and 17F are associated with the risk of development of periodontitis, although the results remain contradictory. Hence, the aim of this study was perform a meta-analysis focusing on two polymorphisms (rs2275913 and rs763780) in interleukins 17A and 17F genes, respectively, in both chronic (CP) and aggressive periodontitis (AgP). A review in literature was performed in several databases for studies published before 25, September 2016. The meta-analysis was obtained through the review manager statistical software (version 5.2) with odds ratio (OR) calculation and funnel plot (P

Background: Our research team believes that the arrangement of the hammock may influence the orthostatic posture. The aim of the present study was to assess the orthostatic posture in right and left views among hammock-users and hammock non-users of northeastern Brazil. Methods: Were included 32 healthy participants, subdivided into two groups: hammock non-users, and hammock-users, both in the last 10 years. The orthostatic posture was performed through photogrammetry analysis (PAS/SAPO). We analyzed body alignment variables: horizontal alignment of the head, vertical alignment of the head, vertical alignment of the trunk, hip angle, body vertical alignments, horizontal alignment of the pelvis, knee angle, and ankle angle. Results: On the right side, there was statistically significant difference in the horizontal alignment of the head ( P = 0.04), hip angle ( P = 0.02), vertical alignment of the body ( P = 0.01) and horizontal alignment of the pelvis ( P = 0.03). In the left side, there was statistically significant difference in horizontal alignment of the head ( P = 0.04) and the horizontal alignment of the pelvis ( P = 0.04). Conclusion: Sleeping in the hammock influenced the orthostatic posture, especially in horizontal alignment of the head, hip angle, the vertical alignment of the body and horizontal alignment of the pelvis in the side views. Our data open new possibilities of research in this area, which has been obscure until this moment, and enable the indication or contraindication to sleep in hammocks.

Background: Low bone mineral density (BMD) predisposes to osteoporosis and elevated risk of fractures. Osteoprotegerin is a soluble molecule associated to metabolism of bone tissue with inhibition of osteoclast-differentiation. Several studies determined the relation among polymorphisms in osteoprotegerin gene and low BMD, but the results are contradictory, so an evaluation about these polymorphisms is necessary. This study carried out a meta-analysis to four polymorphisms in osteoprotegerin gene (A163G, G1181C, T950C, T245G).Methods: A search in literature was made to identify studies with relevant information. The data was extracted by two investigators independently, following a standardized form. The statistical software Review Manager version 5.2 was used to calculation of heterogeneity (I²), Odds Ratio (OR) and Funnel plots with P
