RESUMO
In view of the epidemiological relevance of periodontal disease and chronic noncommunicable diseases, the study aimed to evaluate the relationship between them through subclinical indicators of systemic risk in a population group with healthy habits, including alcohol and tobacco abstinence. A complete periodontal examination of six sites per tooth was performed in a sample of 420 participants from the Advento study (Sao Paulo), submitted to anthropometric and laboratory evaluation. Periodontitis was defined and classified based on the Community Periodontal Index score 3 (periodontal pocket = 4-5 mm) and score 4 (periodontal pocket ≥ 6 mm). The prevalence of mild/moderate and severe periodontitis was 20% and 8.2%, respectively. Both categories of periodontal disease had significantly higher levels of triglycerides, C-reactive protein, calcium score, and calcium percentile, whereas blood glucose after tolerance test was significantly higher among people with severe periodontitis and HDL-c levels were lower (p < 0.05). Young adults with severe periodontitis had significantly higher prevalence of obesity, pre-diabetes, hypertension, and metabolic syndrome. Besides these conditions, the older adults with severe periodontitis had significantly higher prevalence of dyslipidemia and subclinical atherosclerosis. The group with periodontitis had also a higher coronary heart disease risk based on the PROCAM score (p < 0.05). The results indicated associations of periodontitis with several systemic indicators for chronic noncommunicable diseases, and highlighted the need for multiprofessional measures in the whole care of patients.

AIMS: To describe the abundance of major phyla and some genera in the gut microbiota of individuals according to dietary habits and examine their associations with inflammatory markers, insulin resistance, and cardiovascular risk profile. METHODS: A total of 268 non-diabetic individuals were stratified into groups of dietary types (strict vegetarians, lacto-ovo-vegetarians, and omnivores). The taxonomic composition and phylogenetic structure of the microbiota were obtained through the analysis of the 16S rRNA gene. Samples were clustered into operational taxonomic units at 97% similarity using GreenGenes 13.5 database. Clinical, biochemical, and circulating inflammatory markers were compared by ANOVA or Kruskal-Wallis test. RESULTS: The sample (54.2% women, mean age 49.5 years) was composed of 66 strict vegetarians, 102 lacto-ovo-vegetarians and 100 omnivores. Considering the entire sample, the greatest abundant phyla were Firmicutes (40.7 ± 15.9%) and Bacteroidetes (39.5 ± 19.9%), and no difference in abundances was found between individuals with normal and excess weight. Stratifying by dietary types, the proportion of Firmicutes was lower and of Bacteroidetes was higher in strict vegetarians when compared to lacto-ovo-vegetarians and omnivores. At the genus level, strict vegetarians had a higher Prevotella abundance and Prevotella/Bacteroides ratio than the other groups. They also had a lower proportion of Faecalibacterium than lacto-ovo-vegetarians, and both vegetarian groups had higher proportions than did omnivores. Succinivibrio and Halomonas from the Proteobacteria phylum were overrepresented in omnivores. The omnivorous group showed higher values of anthropometric data, insulin, HOMA-IR, and a worse lipid profile. Inflammatory markers exhibited a gradual and significant increase from the vegetarians and lacto-ovo-vegetarians to the omnivorous group. CONCLUSIONS: There are differences in gut microbiota composition of individuals with distinct dietary habits, who differ according to their inflammatory and metabolic profiles. Based on the findings relative to bacteria abundances and on their recognized actions in the metabolism, we suggest that exposure to animal foods may favor an intestinal environment which could trigger systemic inflammation and insulin resistance-dependent metabolic disorders.

Resumo Introdução A perda de inserção clínica periodontal (PIP) tem sido indicada como parâmetro determinante para o estudo de indicadores de risco de periodontite crônica. Objetivo Descrever a prevalência, severidade e extensão de PIP em um grupo populacional que se abstém de álcool e tabaco, além de avaliar associações com características sociodemográficas e comportamentais dos participantes. Método Uma amostra de 420 indivíduos adultos, participantes do Estudo Advento (São Paulo), foi submetida ao exame periodontal de seis sítios por dente e respondeu um questionário estruturado. As associações foram verificadas por meio de análise de regressão logística múltipla. Resultado A prevalência de periodontite foi de 20,7% e de gengivite, 38,8%; a PIP média foi de 1,38 mm (± 0,5) e a perda dental, 5,4 (± 9,0). A prevalência de PIP ≥ 3 mm, ≥ 4 mm e ≥ 6 mm foi de 69,7%, 31,7% e 9,6% dos indivíduos, e 11,4%, 4,4% e 1,2% dos dentes por indivíduo, respectivamente. Houve associação significativa de PIP ≥ 4 mm com sexo masculino, idade superior a 55 anos, baixa escolaridade, placa visível, autocuidado irregular, falta de orientação em higiene bucal e doença sistêmica referida. Para PIP ≥ 6 mm, foi observada maior razão de chances para as variáveis idade e doença sistêmica. Conclusão O grupo populacional estudado apresentou baixa extensão e severidade de PIP, possivelmente pelas características da amostra. As associações de risco encontradas confirmam a necessidade de atenção integral ao paciente, incluindo o incentivo à prevenção e ao controle de doenças crônicas, ao lado de orientações específicas para higiene bucal.
Abstract Introduction Clinical attachment loss (CAL) has been indicated as a determining parameter for the study of risk indicators of chronic periodontitis. Objective To describe the prevalence, severity and extent of CAL in a population group that abstains from alcohol and tobacco use and to evaluate associations with sociodemographic and behavioral characteristics of participants. Method A sample of 420 adult individuals, participants of the Advento Study (São Paulo) were submitted to a periodontal examination of six sites per tooth and answered a structured questionnaire. Associations were verified by multiple logistic regression analysis. Result Prevalence of periodontitis was 20.7% and gingivitis 38.8%; mean CAL was 1.38mm (±0.5) and dental loss 5.4 (±9.0). Prevalence of CAL ≥3 mm, ≥4 mm and ≥6 mm was 69.7%, 31.7% and 9.6% of the individuals, affecting 11.4%, 4.4% and 1.2% of the teeth per individual, respectively. After adjustments, there was a significant association of CAL ≥4 mm with males, over 55 years of age, low education, visible plaque, irregular self-care, lack of oral hygiene guidance and reported systemic disease. For CAL ≥6 mm, there was a higher odds ratio for the variables age group and systemic disease. Conclusion The population group studied presented low extension and severity of CAL, possibly due to the sample characteristics. The risk associations found confirm the need for comprehensive patient care, including encouraging prevention and control of chronic diseases, along with specific oral hygiene guidelines.

O infarto agudo do miocárdio é uma importante manifestação da síndrome isquêmica aguda. Suas seqüelas levam a significativas morbidade e mortalidade, a despeito dos avanços no tratamento dessa doença. A estratificação de risco é fator essencial na determinação dos pacientes potencialmente sujeitos a maior número de complicações e na decisão sobre medidas preventivas das mesmas. O objetivodeste artigo é revisar o conhecimento atual sobre a estratificação de risco da síndrome isquêmica aguda com supradesnível do segmento ST.
