in English, Portuguese, O objetivo deste artigo é analisar as práticas e significados em torno da ultrassonografia obstétrica (USG) em mulheres com abortamento na maternidade pública em Salvador, Bahia, Brasil. Trata-se de uma pesquisa qualitativa, etnográfica, que envolveu observação participante das interações entre mulheres, profissionais de saúde médicos e não médicos, na sala de USG de uma maternidade pública, durante três meses. A USG ocupa um lugar central no itinerário abortivo das mulheres e sua prática é incorporada à rotina institucional e definidora de condutas na atenção ao abortamento na maternidade em estudo. Nesse contexto, são produzidas categorias distintas de “mulheres com aborto”, cujo acionamento depende da interpretação da imagem ecográfica. A forma de significar o estado de saúde e a condição moral de uma mulher com suspeita de aborto se relaciona com a presença ou não de um feto vivo no seu útero, além da idade gestacional em que a tentativa ou efetivação do aborto aconteceu. Concluímos que, quando as evidências ecográficas indicam que houve (provavelmente) um aborto em estágios iniciais de uma gravidez, os próprios profissionais colaboram com as mulheres em desativar o processo semiótico que levaria à atribuição de um sentido de natureza humana ao concepto. Quanto mais tarde se interrompeu uma gestação, mais provável é que o processo de significação sobre as imagens sustente a ideia de que ali havia uma Pessoa. A moral hegemônica sobre aborto e sua criminalização modulam as construções simbólicas e as práticas em torno do exame de USG em mulheres com abortamento.[This corrects the article doi 10.1590/1807-3107bor-2019.vol33.0125].Lipoproteins are important bacterial immunostimulating molecules capable of inducing receptor activator of nuclear factor-κB (RANKL) and osteoclast formation in vitro and in vivo . Although these molecules are present in periodontopathogenic bacteria, their role in periodontitis is not known. In this study, we used Pam2CSK4 (PAM2), a synthetic molecule that mimics bacterial lipoprotein, to investigate the effects of lipoproteins on periodontitis in mice. C57BL/6 male mice were randomly divided into three experimental groups 1) Negative control group animals received vehicle injection; 2) Positive control group animals received injection of Escherichia coli lipopolysaccharide (LPS); 3) PAM2 group animals received PAM2 injection. All the injections were performed bilaterally every other day into the palatal mucosa between first and second molars. After twenty-four days, the animals were euthanized to assess alveolar bone volume (micro-CT), cellular and extracellular composition in the gingiva (stereometric analysis), and osteoclast numbers (TRAP staining). Treatment with either PAM2 or LPS induced gingival inflammation, as demonstrated by increased infiltration of inflammatory cells and enhanced angiogenesis, associated with a smaller number of fibroblasts and decreased extracellular matrix. Importantly, treatment not only with LPS but also with PAM2 resulted in a larger number of TRAP+ multinucleated osteoclasts and significant loss of alveolar bone. Collectively, our data demonstrate that PAM2 can induce gingival inflammation and bone loss in mice, broadening the avenues of investigation into the role of lipoproteins in the pathogenesis of periodontal disease.Relevant public policies in oral health have been implemented in Brazil since 2004. Changes in the epidemiological status of dental caries are expected, mainly in the child population. This study aimed to assess the dental caries experience and associated factors among 12-year-old children in the state of São Paulo, Brazil. A cross-sectional population-based study was conducted with data obtained from 415 cities, including a total of 26,325 schoolchildren who were included by the double-stage cluster technique, by lot and by systematic sampling. The statistical model included data from the São Paulo Oral Health Survey (SBSP 2015), the Human Development Index (HDI) and the Social Vulnerability Index (SVI). A theoretical-conceptual model categorized the variables into three blocks, namely, contextual (HDI, SVI, region of residence and fluoridation of water), individual (sex and ethnicity) and periodontal conditions (gingival bleeding, dental calculus and the presence of periodontal pockets), for association with the experience of caries (DMFT). Statistically significant associations were verified by hierarchical multivariate logistic (L) and Poisson (P) regression analyses (p less then 0.05). The results showed that 57.7% of 12-year-old children had caries experience. Factors that determined a greater prevalence of dental caries in both models were nonwhite ethnicity (ORL = 1.113, ORP = 1.154) and the presence of gingival bleeding (ORL = 1.204, ORP = 1.255). Male children (ORL = 0.920 ORP = 0.859) and higher HDI (ORL = 0.022), ORP = 0.040) were associated with a lower prevalence of dental caries experience. Water fluoridation was associated with a lower DMFT index (ORP = 0.766). Dental caries experience is still associated with social inequalities at different levels. Policymakers should direct interventions towards reducing inequalities and the prevalence of dental caries among 12-year-old children.The sense of coherence (SOC) is a measure of global orientation regarding the ability of individuals to cope with stressful situations. https://www.selleckchem.com/products/pf-06952229.html The aim of the present study was to evaluate the association between SOC and quality of life (QoL) and clinical and sociodemographic characteristics among survivors of oral, oropharynx, hypopharynx, or larynx cancer. A cross-sectional study was conducted with 90 cancer patients in follow up at the Santa Maria University Hospital in southern Brazil who had completed conformal 3D radiotherapy at least three months earlier. QoL was assessed using the University of Washington Quality of Life (UW-QOL) questionnaire and SOC was measured using the Brazilian version of the SOC-13 questionnaire. Data on socio-demographic characteristics and the disease were obtained from patients' charts. Oral clinical conditions were also evaluated. Associations between exploratory variables and mean UW-QOL scores were evaluated through Poisson regression and the results were presented as rate ratios (RR) and 95% confidence intervals (CI).
