Levantamentos epidemiológicos em saúde bucal: análise da metodologia proposta pela Organização Mundial da Saúde

Epidemiological surveys are important for obtaining information on the prevalence and etiology of mouth diseases, since the data collected permit health actions to be planned, performed, and assessed. Methodological uniformity is necessary, however, to maintain reproductibility, validity, and reliability, and to allow national and international comparisons. The initiative of the World Health Organization (WHO) as an advisor in ongoing surveys has been extremely useful, stimulating standardization in all countries. In 1991, a Portuguese version of the 1987 third edition of Oral Health Surveys - basic methods, an instruction manual for performing epidemiological surveys, was published and became a reference for many parts of Brazil and the World. The present analysis found conflicting points in relation to the sample size, calibration of the examiners, and criteria for evaluating oral health and treatment needs. In conclusion, due to the dynamic characteristics of scientific knowledge and, considering the regional differences in relation to the development of oral diseases, we recommend that proposals for standardizing surveys be checked periodically. Other important issues may have not been detected in this analysis, urging a thorough discussion within the dentistry community as a whole.

Construção e validação do instrumento de investigação do conhecimento de gestantes sobre sua saúde bucal e a do seu bebê: perspectiva do cuidado em saúde

INTRODUCTION: Humanized and quality prenatal and post-partum care is critical to maternal and newborn health, as well as oral health care. Currently, the National Oral Health Policy is aiming at expanding dental care for pregnant women. Thus, the promotion of oral health and attention to prenatal care policies should be integrated; however, there is still limited participation of pregnant women. Thus, it is necessary to verify the knowledge of pregnant women related to oral health, seeking to estimate the quality of dental care provided during prenatal care, being essential for the Family Health strategy to organize personnel, plan costs and to ensure the quality standard of care. OBJECTIVE: To develop and validate a research instrument on the knowledge of pregnant women about their oral health and of their baby. METHOD: This is a construction and validation study with 93 pregnant women in Family Health Units and specialized private clinics in Obstetrics, in the city of Natal / RN. It was authorized by the Onofre Lopes University Hospital Ethics Committee of the Universidade Federal do Rio Grande do Norte (UFRN) under the registration number 421.163/13. The construction of the instrument followed steps so that it was valid, reliable and sensitive: creation and reduction of the items (drafting of the instrument), content validity and testing of the instrument, and hypotheses validation. Once constructed, the instrument was evaluated by experts who suggested modifications. There was consultation with the target population about the new version of the created instrument, which had the instrument validation verified by internal consistency through intra and inter-calibration and test-retest. Next, the hypotheses were validated. A database was built in the Statistical Package for Social Sciences (SPSS), version 22.0. After creating the hypotheses, an association was found for validating the criteria between each of the specific issues for each established criteria, considering a 5% significance level. Data analysis was carried out by describing the absolute and relative frequencies of the variables pertaining to issues relating to their pregnancy knowledge about their oral health and their baby. The Kappa coefficient was used for the calibration process (Inter and Intra-examiner calibration) and Cronbach's alpha coefficient was used to analyze instrument reproducibility (test-retest). In addition, the chi-square test was used to cross the dependent variable with the (dichotomized) independent variables. RESULTS: The intra and inter agreement analysis presented a Kappa coefficient between 0.400 and 1.000. Internal consistency through the analysis showed that 90% of the instrument's questions showed great reliability in the answers (Cronbach α ˃ 0.7). In the investigation of the relationship between the dependent variable (knowledge about oral health) and the independent variables (trimester of pregnancy, education, income and multiparous), it was found that none of these independent variables were significantly associated. All hypotheses had their Ho confirmed. CONCLUSION: The constructed instrument was validated, considering that it showed to be sensitive with good reliability and good accuracy, and therefore can be used to assess pregnant women’s knowledge about their oral health and the oral health of their baby.

Infant nutrition and the gut microbiota

Establishment of the intestinal microbiota commences at birth and this colonisation is influenced by a number of factors including mode of delivery, gestational age, mode of feeding, environmental factors and host genetics. As this initial establishment may well influence the health of an individual later in life, it is imperative to understand this process. Therefore, this thesis set out to investigate how early infant nutrition influences the development of a healthy gut microbiota. As part of the INFANTMET project, the intestinal microbiota of 199 breastfed infants was investigated using both culture-dependent and culture-independent approaches. This study revealed that delivery mode and gestational age had a significant impact on early microbial communities. In order to understand host genotype-microbiota interactions, the gut microbiota composition of dichorionic triplets was also investigated. The results suggested that initially host genetics play a significant role in the composition of an individual’s gut microbiota, but by month 12 environmental factors are the major determinant. To investigate the origin of hydrogen sulphide in a case of nondrug- induced sulfhemoglobinemia in a preterm infant, the gut microbiota composition was determined. This analysis revealed the presence of Morganella morganii, a producer of hydrogen sulphide and hemolysins, at a relative abundance 38%, which was not detected in control infants. Following on from this, the negative and short term consequences of intrapartum antibiotic prophylaxis exposure on the early infant intestinal microbiota composition were demonstrated, particularly in breast-fed infants, which are recovered by day 30. Finally, the composition of the breast milk microbiota over the first three months of life was characterised. A core of 12 genera were identified amongst women and the remainder comprised some 195 genera which were individual specific and subject to variations over time. The results presented in this thesis have demonstrated that the development of the infant gut microbiota is complex and highly individual. Clear alterations in the intestinal microbiota establishment process in C-section delivered, preterm and antibiotic exposed infants were shown. Taken together, long-term health benefits for infants, particularly those vulnerable groups, may be conferred through the design of probiotic and prebiotic food ingredients and supplements.

Treatment of Clostridium difficile infection: a national survey of clinician recommendations and the use of faecal microbiota transplantation

Adherence to Clostridium difficile infection treatment guidelines is associated with lower recurrence rates and mortality as well as cost savings. Our survey of Irish clinicians indicates that patients are managed using a variety of approaches. FMT is potentially underutilised despite its recommendation in national and European guidelines.

Saúde bucal no Programa de Saúde da Família : o caso do Distrito Sanitário Norte de Natal-RN

The inclusion of the dentist in the Family Health Program (FHP) teams designates a reorganization of the mouth health care in your country and establishes a new scenario in Brazilian odontology, through of a new way to organize the basic health care, creating conditions to consolidate in mouth health practice actions, in the level of the basic attention, the validation of Unique Health System (UHS) constitutional principles. The purpose of this research is to verify if the actuation of mouth health teams (MHT) dentists, in Natal city north sanitary district, is tuned with FHP goals.The target research population was composed by all dentists working in Basic Health Units (BHU) of Natal north sanitary district. Fifth-eight questionnaires were applied and using open and closed questions we look for identify the functional characteristics of each BHU, the dentists professional attributions on each BHU, as well as the clinical procedures that they execute. This research also searched to identify the factors that facilitate and/or difficult the inclusion process and the dentists activities performance on these BHUs, as well as the necessary actions to north sanitary district MHTs to fulfill the objectives proposed by FHP. The results point that the inclusion of mouth health actions in north sanitary district FHPs brought the incorporation of new values to the used practices. Whoever, its necessary a more frequent evaluation of the carried actions, in a way they can be adapted to the real community necessities, and, is fundamental the data accompaniment, for that these serve of base for planning and redirecting activities, in a way that we do not have only a reproduction of traditional practices, fragmented and isolated, but a truly substitution of the traditional practices and a new way of promoting health

Gut Microbiota, Probiotics and Diabetes

Diabetes is a condition of multifactorial origin, involving several molecular mechanisms related to the intestinal microbiota for its development. In type 2 diabetes, receptor activation and recognition by microorganisms from the intestinal lumen may trigger inflammatory responses, inducing the phosphorylation of serine residues in insulin receptor substrate-1, reducing insulin sensitivity. In type 1 diabetes, the lowered expression of adhesion proteins within the intestinal epithelium favours a greater immune response that may result in destruction of pancreatic β cells by CD8+ T-lymphocytes, and increased expression of interleukin-17, related to autoimmunity. Research in animal models and humans has hypothesized whether the administration of probiotics may improve the prognosis of diabetes through modulation of gut microbiota. We have shown in this review that a large body of evidence suggests probiotics reduce the inflammatory response and oxidative stress, as well as increase the expression of adhesion proteins within the intestinal epithelium, reducing intestinal permeability. Such effects increase insulin sensitivity and reduce autoimmune response. However, further investigations are required to clarify whether the administration of probiotics can be efficiently used for the prevention and management of diabetes.

Respiração bucal

Introdução: A respiração nasal é a única considerada fisiológica para o ser humano, e proporciona o normal crescimento e desenvolvimento do complexo craniofacial. Qualquer alteração no mecanismo funcional poderá alterar o equilíbrio e conduzir a desvios da normalidade e a consequentes deformidades. Além de afetar as estruturas craniofaciais, a respiração bucal poderá afetar também as estruturas dentárias. Objetivo: Determinar a influência da respiração oral nas alterações oro-faciais, por meio de uma revisão da literatura publicada sobre o tema. Materiais e métodos: Foi realizado um levantamento bibliográfico de dados utilizando motores de busca eletrónicos, livros científicos e teses de mestrado. Os artigos foram selecionados segundo o seu nível de evidência científica. Resultados: A respiração oral é uma síndrome comum nas crianças em idade escolar, que se encontram em fase de crescimento e de desenvolvimento dos padrões craniofaciais. As possíveis alterações da função respiratória podem dar origem a modificações dentárias e faciais nestes pacientes. Conclusões: O diagnóstico precoce da respiração oral é de extrema importância, uma vez que pode influenciar o correto desenvolvimento da cavidade oral e do complexo craniofacial. Quando detetada deve-se procurar realizar uma avaliação das vias aéreas e dos possíveis hábitos orais do paciente. Em seguida é efetuada uma intervenção adequada e eficaz com o intuito de minimizar as consequências decorrentes da respiração oral.
