Objectives: It was evaluated epidemiological aspects of primary lip squamous cell carcinoma (LSCC) and its associations with clinicopathological factors. Study design: This retrospective, cross-sectional study analysed a sociodemographic, clinical, and morphological data of HNSCC in a Brazilian population (n=30). Data analysis included descriptive statistics and bivariate analyses using the chi-square and Fisher's exact tests to compare the variables. Results: The LSCC represented 10.8% of all oral cavity squamous cell carcinoma. Lip malignant disease was more prevalent in elderly men, with male-to-female ratio of 5:1. Lower lip was more affected. It was observed high rates of chronic solar exposure, and tobacco and alcohol drinking habits. Clinically, early TNM staging, small tumour lesions, and non-metastatic disease were predominant findings. It was identified a high frequency of well differentiated tumor samples. Worse Karnofsky performance status was associated with cervical metastasis. Conclusions: Our findings showed that LSCC patients exhibited similar epidemiological and clinical profiles as noted in other studies. Still, the occurrence of metastatic disease was associated with a worse physical performance status of the LSCC patients during diagnosis.
Taken together, these results show that chronic high circulating angiotensin-(1-7) levels protect against metabolic stress induced by a high-fat diet decreasing the proinflammatory profile of adipose tissue.
Abstract-Angiotensin (Ang)-(1-7) has been described as an important tool on treating and preventing metabolic disorders. In this study, we aimed to evaluate the effect of an oral formulation of Ang-(1-7) included in hydroxypropylβ-cyclodextrin (HPβCD/Ang- [1][2][3][4][5][6][7]) on hepatic function, steatosis, and on liver inflammatory markers expression in mice treated with a high-fat diet. Male FVB/N mice were divided into 4 groups and fed for 60 days, with each group receiving 1 of the following diets: standard diet+HPβCD, standard diet+Ang-(1-7)/HPβCD, high-fat diet+HPβCD, or highfat diet+Ang-[1-7]/HPβCD. Body weight, food intake, and blood parameters, such as total cholesterol, triglyceride, alaninetransaminases, and aspartate transaminases, were evaluated. Immunohistochemical analyses were performed for inflammatory markers tumor necrosis factor-α and interleukin-6. Expression of angiotensin converting enzyme, angiotensin-converting enzyme-2, interleukin-1β, tumor necrosis factor-α, interleukin-6, transforming growth factor-β, acetyl-CoA carboxylase, carbohydrate-responsive element-binding protein, peroxisome proliferator-activated receptor-γ, and sterol regulatory element-binding proteins-1c was evaluated by quantitative real-time polymerase chain reaction. The major findings of our study included reduced liver fat mass and weight, decreased plasma total cholesterol, triglyceride, and alaninetransaminase enzyme levels in the oral Ang-(1-7)-treated groups compared with the control groups. These results were accompanied by a significant reduction in tumor necrosis factor-α and interleukin-6 mRNA expression in the liver. Analyses of liver adipogenesis-related genes by quantitative real-time polymerase chain reaction showed that acetyl-CoA carboxylase, peroxisome proliferator-activated receptor-γ, and sterol regulatory element-binding proteins1c mRNA expression were significantly suppressed. In conclusion, we observed that treatment with Ang-(1-7) improved metabolism and decreased proinflammatory profile and fat deposition in liver of mice. The renin-angiotensin system (RAS) is now recognized to play an important role in the development of cardiovascular and metabolic disorders. [10][11][12][13] The RAS consists primarily of an enzymatic cascade in which angiotensinogen is converted to angiotensin (Ang) I and subsequently to Ang II by the actions of renin and Ang-converting enzyme (ACE), respectively. 14 Ang-(1-7) is formed mainly from Ang II by ACE-2 and indirectly from Ang I.14 The ACE-2/Ang-(1-7)/Mas axis has been suggested as an important counter-regulatory arm in the RAS with effects opposing those of ACE/Ang II/Ang II receptor, type 1. 13Recent studies showed an important participation of RAS in the nonalcoholic fatty liver disease (NAFLD) development and progression. The Ang II has been implicated as a major player in the altered hepatic lipid metabolism observed in NAFLD. Genetic disruption of several RAS components in rodent models results in a protection from high-fat diet (HFD)-induced obesity. [15...
Analysis of socio-demographic and systemic health factors and the normative conditions of oral health care in a population of the Brazilian elderly Objective: To investigate the association of socio-demographic and systemic health factors according to the normative conditions of oral health care (dental caries, edentulism, periodontal disease and oral mucosal lesion) in elderly individuals. Material and methods: A cross-sectional study was carried out in a group of elderly with access to community health care (n = 200). The normative conditions of oral health were then investigated according to the WHO and the SB Brazil criteria. Bivariate analyses were evaluated by the chi-square test and Fisher's exact test. An estimation of prevalence for the covariates was performed using Poisson's regression models. Results: The prevalence of edentulism and oral mucosal lesions was detected in 58% and 21.5% of elderly patients, respectively. In the dentate subjects, the prevalence of dental caries and periodontal disease was 51.2% and 20.8%, respectively. Older men and individuals from lower-income groups exhibited a higher prevalence of dental caries. Elderly women, illiterate individuals, and individuals over the age of 65 years exhibited a higher prevalence of edentulism. Elderly 60-64 years old and those who are employed had a significant association with periodontal disease. Conclusion: Socio-demographic factors were associated with some notable oral diseases in the elderly.
