RESUMO
Microplastics are ubiquitous contaminants of marine ecosystems around the world and Antarctica is no exception. Microplastics can be influenced by sedimentary dynamics mainly on coastal areas where they are more abundant in Antarctica. This study evaluated microplastic contamination in beach environments from two Antarctic Specially Protected Areas, aiming to identify relationships between microplastic numbers and sedimentological parameters on beach sediments. Low numbers of microplastics were found (> 0.5 mm; fibers excluded) - one particle per sample in 4 of 15 samples analyzed - and there is no evidence of widespread contamination. Sedimentological parameters reveal differences between sampled environments, but low numbers of microplastics impaired statistical comparison. All sediment samples are coarse, denoting highenergy depositional environments that are likely little susceptible to microplastic accumulation. Microplastic contamination in the Antarctic coastal ecosystem is heterogeneous, and their detailed characterization assisted by a systematization of methods can improve the understanding of microplastics distribution patterns in the cold coastal ecosystem.

STATEMENT OF PROBLEM: The accuracy of impressions for implant-supported prostheses is essential to ensure a passive fit of the definitive prosthesis. Intraoral scanners (IOSs) have been developed as an alternative to complete-arch implant-supported restorations; however, whether they are sufficiently accurate when more than 3 nonaligned implants are involved is unclear. PURPOSE: The purpose of this pilot clinical study was to determine whether the fit of complete-arch zirconia implant-supported frameworks processed on a cast obtained with an IOS and adjusted with an auxiliary device is equivalent to a prosthesis obtained from an elastomeric impression. MATERIAL AND METHODS: Twelve consecutive participants who were ready for complete-arch restorations on already osseointegrated implants were enrolled. Two records were made, one open-tray with polyether and splinted impression copings and the second with an IOS. A verification gypsum device was used for the elastomeric impression, and a prefabricated auxiliary device was used to adjust the intraoral scans. Two zirconia frameworks with the same design were processed and evaluated intraorally by 2 independent calibrated observers. RESULTS: In 11 of the 12 participants, the digitally processed prosthesis was preferred over the conventionally processed prosthesis. The clinical fit of the prostheses obtained with the completely digital workflow was better than that of those obtained with the conventional workflow. CONCLUSIONS: The use of a prefabricated auxiliary device after intraoral scanning allowed delivery of complete-arch implant-supported monolithic zirconia prostheses with a fit better than those fabricated from conventional impressions.

OBJECTIVES: To investigate the presence of soft tissue calcifications in the head and neck region on panoramic radiographs of older adults. METHODS: We analysed 1176 panoramic radiographs obtained between January 2013 and December 2018 from individuals of both sexes aged 60 years or older, who were referred by dental specialities to the Dental Imaginology Service of the Federal University of Rio Grande do Norte, Brazil. The types of soft tissue calcification evaluated were as follows: carotid artery calcification (CAC), thyroid cartilage calcifications, triticeous cartilage calcifications, sialoliths, tonsilloliths and lymph node calcifications. The presence of soft tissue calcifications was correlated with age and sex. The chi-square test with continuity correction was used for the calculation of p values and the evaluation of the proposed associations. Prevalence ratios and 95% confidence intervals were also calculated. RESULTS: At least one type of soft tissue calcification was found in 43% of the sample. The main calcifications detected were CAC, thyroid and triticeous cartilage calcifications, tonsilloliths, sialoliths, calcified lymph nodes, and phleboliths. Mean patient age was 67.47 years and there was a predominance of females (62.8%) in the sample. Bivariate analysis showed a statistically significant association between female sex and the presence of thyroid and triticeous cartilage calcifications and between male sex and the presence of tonsilloliths. CONCLUSION: Routine panoramic radiography permits the identification of soft tissue calcifications that may be indicators of future cardiovascular disorders, the referral to a medical service and the establishment of therapies for stroke prevention.

Bulimia is an eating disorder with a great prevalence in young women. Due to its multifactor ethiology, bulimia has systemic consequences. In the literature, necrotising sialometaplasia is seldom associated with bulimia. Its etiopathogenesis is discussed by several authors; nevertheless, the consensus does not consider the relevance of local trauma associated with induced vomiting. A case of necrotising sialomethaplasia, presented with a single hard palatal ulcer in a bulimic woman is described in the present report. The patient did not present significant systemic laboratorial values, nor physical weight variations, which highlights the relevance of performing a complete medical clinical history when diagnosing this rare pathology.

Grit basting is the most common process applied to titanium dental implants to give them a roughness that favors bone colonization. There are numerous studies on the influence of roughness on osseointegration, but the influence of the compressive residual stress associated with this treatment on biological behavior has not been determined. For this purpose, four types of surfaces have been studied using 60 titanium discs: smooth, smooth with residual stress, rough without stress, and rough with residual stress. Roughness was studied by optic interferometry; wettability and surface energy (polar and dispersive components) by contact angle equipment using three solvents; and residual stresses by Bragg-Bentano X-ray diffraction. The adhesion and alkaline phosphatase (ALP) levels on the different surfaces were studied using Saos-2 osteoblastic cultures. The bacterial strains Streptococcus sanguinis and Lactobacillus salivarius were cultured on different surfaces, determining the adhesion. The results showed that residual stresses lead to increased hydrophilicity on the surfaces, as well as an increase in surface energy, especially on the polar component. From the culture results, higher adhesion and higher ALP levels were observed in the discs with residual stresses when compared between smooth and roughened discs. It was also found that roughness was the property that mostly influenced osteoblasts' response. Bacteria colonize rough surfaces better than smooth surfaces, but no changes are observed due to residual surface tension.
RESUMO
Purpose: The purpose of this cross-sectional study was to evaluate the association between clinician-assessed (actual) and self-assessed (perceived) dentofacial features and their association with bullying in schoolchildren. Methods: The sample comprised 519 schoolchildren aged 10 to 12 years old (235 boys and 284 girls) randomly selected from private and public schools. Clinical evaluations were performed to record dento- facial features, and the children were asked a self-reported questionnaire about their personal experience of bullying and perceived dentofacial features. Descriptive statistics (counts and percentages) as well as chi-square to analyze the association between variables were applied. Results: The results showed that 57.2 percent of the children reported being bullied, and the mainly perceived dentofacial features cited were: "crooked teeth" (46.3 percent), "shape or color of teeth" (45.5 percent), "upper front teeth sticking out" (43.8 percent), and "having a gap between the teeth or having missing teeth" (35.5 percent). Statistically significant associations between actual and perceived dentofacial features and involve- ment in bullying were observed for anterior crowding (P=0.01), anterior crossbite (P<0.001), lip competence (P=0.008), and anterior dental trauma (P=0.04). Conclusion: Some actual and perceived dentofacial traits are associated with bullying, so these features and the schoolchil- dren's compliances should be considered to determine the treatment need.

Lipomas can occur anywhere in the body where fat cells are present; however, intraosseous lipomas are rare. Although solitary lesions have already been reported in the gnathic bones, to the best of our knowledge, this is the first case of bilateral intraosseous lipoma. A 62-year-old woman was referred for evaluation of a swelling on both maxillary tuberosities. The radiographic examination showed a mixed radiolucent-radiopaque image with ill-defined borders on the right side of the maxilla, and an ill-defined radiolucency on the left side. Histologically, both sides revealed numerous mature adipocytes surrounded by immature bone and dystrophic calcification. The patient remains under follow-up and free of disease for 8 months. Due to the rarity of the intraosseous lipomas in the jaws, a literature review of the published cases was performed jointly with this unique case report.

PURPOSE: To determine whether the accuracy of two-implant model impressions taken with optical scanners was inferior to that of those taken with elastomeric materials. MATERIALS AND METHODS: Impressions of a resin reference model with two almost parallel implants were taken using three elastomeric impressions (closed tray technique, open tray nonsplinted technique and open tray splinted technique) and scanned with four optical scanners (CEREC Omnicam, 3M True Definition Scanner, 3Shape TRIOS3 and Carestream CS 3600). STL files of the different methods were superimposed and analyzed with control software (Geomagic Control X, 3D systems) to determine the mean deviation between scans. RESULTS: Compared to elastomeric impressions, optical impressions showed a significantly improved mean precision. TRIOS3 and CS3600 showed a significantly improved mean trueness compared to that of closed tray, CEREC Omnicam and TrueDefinition. All methods showed a certain degree of implant rotation over their axes, which was significantly higher in the closed tray and the open tray nonsplinted techniques. CONCLUSIONS: Optical impressions, taken under these in vitro conditions, showed improved accuracy compared with that of elastomeric impressions.

The uncertain relationship between genotype and phenotype can make strain engineering an arduous trial and error process. To identify promising gene targets faster, constraint-based modeling methodologies are often used, although they remain limited in their predictive power. Even though the search for gene knockouts is fairly established in constraint-based modeling, most strain design methods still model gene up/down-regulations by forcing the corresponding flux values to fixed levels without taking in consideration the availability of resources. Here, we present a constraint-based algorithm, the turnover dependent phenotypic simulation (TDPS) that quantitatively simulates phenotypes in a resource conscious manner. Unlike other available algorithms, TDPS does not force flux values and considers resource availability, using metabolite production turnovers as an indicator of metabolite abundance. TDPS can simulate up-regulation of metabolic reactions as well as the introduction of heterologous genes, alongside gene deletion and down-regulation scenarios. TDPS simulations were validated using engineered Saccharomyces cerevisiae strains available in the literature by comparing the simulated and experimental production yields of the target metabolite. For many of the strains evaluated, the experimental production yields were within the simulated intervals and the relative strain performance could be predicted with TDPS. However, the algorithm failed to predict some of the production changes observed experimentally, suggesting that further improvements are necessary. The results also showed that TDPS may be helpful in finding metabolic bottlenecks, but further experiments would be required to confirm these findings.

A 53-year-old female appeared with pain in the right mandible ramus, for the past 9 months, after tooth extraction. Clinical and radiological examination using conventional and advanced computerized tomography diagnostic imaging led to a provisional diagnosis of multiple complex odontomas. Complete conservative excision of the lesion was performed. The clinical diagnosis was confirmed histopathologically. Postoperative period was uneventful with no evidence of recurrence. According to an extensive literature review, this report describes the oldest patient ever diagnosed with multiple odontomas in the literature.
RESUMO
OBJECTIVE: The aim was to correlate radiomorphometric indices and biochemical analyses as an auxiliary method in bone evaluation in male and female patients with chronic kidney disease-mineral and bone disorder (CKD-MBD) and controls. MATERIALS AND METHODS: Nine radiomorphometric indices and four biochemical parameters were obtained: mental index (MI), height at the mental foramen, total mandibular height (THM), panoramic mandibular index (PMI), original height of the mandible, alveolar bone resorption, distance from the mental foramen to the alveolar bone crest (MF-ABC), mandibular cortical index (MCI), trabecular bone pattern, parathyroid hormone (PTH), calcium (Ca), phosphorus (P), and Ca × P product (Ca × P). STATISTICAL ANALYSIS: The Mann-Whitney U-test, chi-squared test, and Spearman's correlation were applied at a significance level of 95%. RESULTS: There was a moderate negative and significant correlation between MI, PMI, and PTH in female patients with CKD-MBD as well as between THM, MF-ABC, and Ca × P. The MCI and trabecular bone pattern indicated altered bone quality in male patients. CONCLUSIONS: The radiomorphometric evaluation was an auxiliary, noninvasive method to detect possible alterations in the cortex and mandibular bone trabeculation in male and female patients with CKD-MBD.
RESUMO
OBJECTIVES: The aim of this study was to investigate the presence and associated factors of carotid artery calcification (CAC) in patients with chronic kidney disease (CKD) undergoing hemodialysis. STUDY DESIGN: A total of 309 panoramic radiographs of patients with CKD (180 men and 129 women; mean age 43.7 years) undergoing hemodialysis were evaluated by a single radiologist to determine the frequency of CAC. An analysis of associated factors, such as age, sex, time spent in hemodialysis, arterial hypertension, diabetes mellitus, biochemical parameters, and other systemic diseases, was also performed. RESULTS: The presence of CAC in patients with CKD, as determined on the basis of panoramic radiography, was 15.9%. The χ2 test revealed that there was a statistically significant association between certain factors, such as age, sex, and diabetes mellitus, and the presence of CAC (P < .05). Multivariate analysis demonstrated that time spent in hemodialysis was significantly associated with the occurrence of CAC. CONCLUSIONS: A significant presence of CAC was detected on digital panoramic radiographs in patients with CKD undergoing hemodialysis. Calcification was more frequent in older patients, women, individuals with diabetes mellitus, and patients who had undergone hemodialysis for longer periods.

OBJECTIVE: To evaluate the relationship between temporomandibular disorders (TMD) and craniocervical posture in the sagittal plane measured from lateral radiographs of the head. METHODS: The sample was comprised of 80 randomly selected students of dentistry at the Federal University of Rio Grande do Norte. Research Diagnostic Criteria for TMD (RDC/TMD) was used to evaluate the signs and symptoms of TMD. Lateral radiographs of each individual were used to measure the position of the hyoid bone, the craniocervical angle, and the occiput-atlas distance. A chi-square test was used to evaluate the relationships between craniocervical posture measures and TMD. RESULTS: No relationship was found between TMD and the craniocervical posture measured by the positioning of the hyoid bone, head rotation, and the extension/flexion of the head (p > 0.05). CONCLUSION: It can be concluded, therefore, that no relationship exists between cervical posture in the sagittal plane and TMD.

Objetivo: Avaliar a prevalência e o grau de gravidade da DTM em policiais militares e analisar a associação entre DTM e hábitos parafuncionais. Métodos: Realizou-se uma pesquisa transversal com abordagem quantitativa. A amostra foi composta por 255 policiais militares, com idade entre 20 a 53 anos, de ambos os gêneros, nos estados do Maranhão, Pará e Tocantins. Foram utilizados três questionários para avaliar variáveis de caracterização amostral, prevalência e gravidade da DTM e hábitos parafuncionais. Os questionários foram enviados por plataforma eletrônica (Google Forms). Foram utilizados o teste qui-quadrado de Pearson ou o teste Exato de Fisher e Odds Ratio. Resultados: Observou-se a presença da Disfunção Temporomandibular em 66,3% dos pesquisados, dos quais 40,4% apresentaram a disfunção no grau leve, 21,6% no grau moderado e 4,3% no grau grave. Houve associação significativa entre os hábitos parafuncionais de ranger e apertar dentes, roer unhas, morder objetos, morder bochecha, mastigar e dormir de um lado só e apoiar a mão da mandíbula com a DTM (p < 0,05). A gravidade leve não apresentou associação estatisticamente significativa com os hábitos, apenas os graus moderado e grave. Conclusão: Concluiu-se que 66,3% dos pesquisados apresentaram DTM, sendo maior a prevalência do grau leve e houve associação entre a DTM e os hábitos parafuncionais, com exceção aos de mascar chiclete e chupar dedo.
Aim: To evaluate the prevalence and severity of Temporomandibular disorder (TMD) in officers of the police force and to analyze the association between TMD and parafunctional habits. Methods: A cross-sectional research with a quantitative approach was carried out. The sample consisted of 255 police officers, from 20 to 53 years of age, of both genders, in the states of Maranhão, Pará, and Tocantins. Three questionnaires were used to evaluate variables of sample characterization, prevalence, and severity of TMD and parafunctional habits. The questionnaires were sent via electronic platform (Google Forms). Pearson's chi-square test or Fisher's exact test and Odds Ratio were used. Results: The presence of Temporomandibular Dysfunction was observed in 66.3% of those surveyed, of whom 40.4% presented the dysfunction in a mild degree, 21.6% in a moderate degree, and 4.3% in a severe degree. A significant association was observed between parafunctional habits of grinding and clenching teeth, biting nails, biting objects, biting cheeks, chewing and sleeping on one side, and resting one Ìs hand on the jaw with TMD (p < 0.05). Mild severity showed no statistically significant association with habits, only moderate and severe degrees. Conclusion: It was concluded that 66.3% of those surveyed had TMD, with a higher prevalence of the mild degree. In addition, an association was observed between TMD and parafunctional habits, with the exception of chewing gum and thumb sucking.

Introdução: A AIDS (Síndrome da Imunodeficiência Adquirida) é a doença causada pela infecção do Vírus da Imunodeficiência Humana (HIV) e é uma infecção sexualmente transmissível. O HIV é um retrovírus, classificado na subfamília dos Lentiviridae. Atualmente, ainda ocorrem casos de discriminação em consultórios odontológicos a pacientes portadores de HIV/AIDS, apesar de todas as informações sobre a doença, na hora do atendimento os profissionais ainda possuem receio e dúvida quanto ao protocolo de atendimento. Objetivo: Avaliar os aspectos éticos do atendimento odontológico de pacientes portadores HIV/AIDS na cidade de Imperatriz-Maranhão, sob a percepção dos mesmos. Material e Método: Foi aplicado um questionário estruturado a 100 pacientes portadores de HIV/AIDS que estavam em tratamento no Centro de Atenção Psicossocial (CAPS) do município de Imperatriz- MA, CAPS III e CAPS AD III, entre os meses de março e abril de 2019. Resultado: Os participantes relataram que sofreram discriminação (41% - 41) em algum momento do atendimento odontológico, 85% (85) dos pacientes não informariam ao cirurgião-dentista que é portador do HIV, sendo o constrangimento (14% - 14) o principal motivo para não informar. Conclusão: O índice de discriminação nos atendimentos odontológicos a pacientes portadores HIV/AIDS no município de Imperatriz-MA é elevado. Há necessidade dos cirurgiões-dentistas buscarem atualizar-se sobre o vírus HIV e a doença AIDS, e sobre aspectos éticos e legais do atendimento a pacientes portadores dessa morbidade, para garantir um atendimento seguro, de qualidade e humanizado.

Acquired inhibitors of coagulation causing bleeding manifestations are rare in children. They emerge, normally in the context of autoimmune diseases or drug ingestion, but transient and self-limiting cases can occur after viral infection. We describe, an otherwise healthy, 7-year-old girl who had gingival bleeding after a tooth extraction. The prothrombin time (PT) and the activated partial thromboplastin time (APTT) were both prolonged with evidence of an immediate acting inhibitor (lupic anticoagulant). Further coagulation studies demonstrated prothrombin (FII) deficiency and prothrombin directed (FII) antibodies. The serological tests to detect an underlying autoimmune disease were all negative. The coagulation studies normalised alongside the disappearance of the antibody. This article presents lupus anticoagulant hypoprothrombinaemia syndrome (LAHS) as a rare case of acquired bleeding diathesis in childhood.

O objetivo deste artigo foi avaliar a condição de saúde bucal de crianças internadas no Hospital Municipal Infantil de Imperatriz - MA. A amostra foi constituída por 80 crianças de ambos os sexos, com idade entre 02 e 12 anos, hospitalizadas por no mínimo 03 dias. Quanto à distribuição da média do ceo-d e CPO-D por idade, as crianças hospitalizadas de 05 a 07 anos apresentaram índice de cárie mais elevado. O IHOS, na faixa etária entre 02 e 05 anos, revelou uma higiene bucal insatisfatória. Constatouse que a saúde bucal das crianças hospitalizadas está comprometida, com um alto índice de cárie na dentição decídua. A higiene bucal não ocorre nem de forma sistemática, nem orientada durante o período de hospitalização, havendo uma baixa adesão aos procedimentos de higiene bucal.
The aim of this paper was to evaluate the oral health status of children hospitalized at Childrens Municipal Hospital Imperatriz - MA. The sample consisted of 80 children of both sexes, aged between 02 to 12 years hospitalized for at least 03 days. As for the distribution of the average ceo-d and CPOD age, hospitalized children 05 to 07 years had higher caries prevalence. The IHOS, aged between 02 to 05, revealed a poor oral hygiene. It was found that the oral health of hospitalized children is committed, with a high index of caries in the primary dentition. The oral hygiene does not occur neither systematically nor targeted during the hospitalization period, with a low adherence to oral hygiene procedures.
RESUMO
O objetivo deste trabalho foi avaliar o grau de conhecimento sobre trauma dentário e uso de protetor bucal entre estudantes do curso de educação física, de uma faculdade particular, da cidade de Imperatriz-MA . Um estudo transversal foi realizado com 46 acadêmicos, através de um questionário contendo questões objetivas sobre avulsão dentária e uso de protetor bucal. Após responderem todo o questionário, os mesmos receberam folhetos explicativos sobre o tema. Os dados obtidos foram trabalhados em planilha Excel e analisados no programa estatístico SPSS versão 18, por meio de análise descritiva, através valores absolutos e percentuais. Os resultados mostraram que 57% dos entrevistados não tiveram no decorrer de sua formação orientações sobre traumatismo dentário e 48% afirmaram que recolocariam no alvéolo um dente decíduo avulsionado. Com relação a correta manipulação do elemento avulsionado, a maioria (61%) manipularia pela raiz ou coroa/raiz juntas e 33% dos alunos colocariam o dente avulsionado em um guardanapo limpo até que a criança fosse ao dentista e apenas 11% acondicionariam o elemento dental em leite fresco. A respeito do método de prevenção do trauma dental, apenas 30% optou pelo uso de protetor bucal. Com isso, pode-se concluir que os estudantes de educação física apresentam carência de informações sobre o tema em questão, evidenciando-se a necessidade de inclusão de cursos e palestras sobre primeiros socorros em relação à avulsão dentária durante a formação desses futuros profissionais
The objective of this study was to evaluate the degree of knowledge about dental trauma and use of mouthguard between undergraduate students of physical education, a private college in the city of Imperatriz-MA. A cross-sectional study was conducted with 46 students through a questionnaire with objective questions about tooth avulsion and a mouth protector. After answering all the quiz, they received brochures on the subject. The data were worked into an Excel spreadsheet and analyzed in SPSS version 18, using descriptive analysis, through absolute and percentage values. The results showed that 57% of respondents did not have in the course of their training guidance on dental injuries and 48% said they recolocariam the alveoli one primary tooth avulsed. Regarding the correct handling of the avulsed element, the majority (61%) manipulate the root or crown / root together and 33% of students would place the tooth avulsed in a clean napkin until the child went to the dentist and only 11% acondicionariam the element dental fresh milk. Regarding dental trauma prevention method, only 30% chose to use mouthguard. Thus, it can be concluded that physical education students have lack of information about the subject in question, demonstrating the need for inclusion of courses and lectures on first aid in relation to dental avulsion during the training of future professionals

Introdução: a violência no idoso é um problema multicausal e complexo, com consequências devastadoras, pois, além de agressões à saúde física e mental acarreta baixa qualidade de vida e falta de segurança. Estudar esta temática verificando os fatores determinantes é relevante para a prevenção da ocorrência de violência em idosos. Objetivo: analisar a ocorrência da violência em idosos e seus fatores determinantes em Betim, Minas Gerais. Método: Estudo transversal, constituído por inquérito populacional realizado por meio de entrevistas estruturadas. A amostra foi estratificada por conglomerados em três estágios: setores censitários, domicílios e o respondente. Ao final, foram visitados 1.129 domicílios, com a participação de 200 idosos. A seleção dos setores censitários e dos domicílios foi realizada eletronicamente por meio do Statistical Package for Social Science (SPSS) versão 20.0 e a seleção do sujeito respondente no domicílio ocorreu segundo a metodologia de Kish, que preconiza a seleção aleatória de uma unidade amostral num domicílio. Inicialmente, os dados foram analisados pelo teste Qui-quadrado, análise bivariada e Análise de Correspondência. Posteriormente, realizou-se uma análise discriminante logística para explorar a estrutura de relações entre as variáveis dependentes (violência no idoso) e independentes. Resultados: As formas mais prevalentes de violência foram: falta de acesso a direitos sociais (31%) seguidos pela violência verbal (22%), moral/psicológica (19%), falta de cuidados necessários (16%); física (6%), sexual (3%) e discriminação (3%). Os homens que sofreram violência não eram dependentes, mantinham o controle do seu dinheiro e possuíam cônjuge. Já nas mulheres encontrou-se um maior número de dependentes, que não tinham controle do seu dinheiro, com escolaridade > 4ª série, sem cônjuge e com alto grau de sintomas depressivos. A associação considerada forte refere-se às idosas que sofreram violência e tiveram o seu dinheiro usado por outra pessoa e que sofreram violência verbal. Conclusão: este estudo permitiu reafirmar o perfil do idoso vítima de violência através da análise de sua ocorrência e seus fatores associados. Os fatores abuso financeiro e ser vítima de violência verbal foram fortemente associados à violência na pessoa idosa resultado que configura um novo olhar para esses fatores, visto que no Brasil, os principais fatores associados descritos anteriormente, foram baixos níveis educacionais, fatores cognitivos, dependência funcional e depressão. Do ponto de vista de investigação para ação, a presente pesquisa traz implicação direta para os setores interessados no enfrentamento do problema da violência no idoso, especialmente para os profissionais de saúde, pois, evidencia que a violência faz parte de um ciclo que geralmente tem fatores associados característicos que fazem parte de um modelo aninhado, principalmente, no relacionamento familiar. Nossa expectativa é que o silêncio do idoso, vítima de violência, sirva para aguçar a escuta dos profissionais de saúde e que os determinantes aqui descritos sejam encarados como disparadores da detecção e prevenção de novos casos. Por fim, cabe-nos destacar que o estudo da violência no idoso reclama, agora, que seus achados sejam subsidiários da práxis em saúde, conferindo novas estratégias e métodos para a cultura de paz e não violência.(AU)
Health and violence in the elderly population of Betim, Minas Gerais Introduction: Violence in the elderly is a multicausal and complex problem, with devastating consequences, as well as aggression to physical and mental health leads to poor quality of life and lack of safety. Studying this thematic one verifying the determining factors is relevant for the prevention of the occurrence of violence in the elderly. Objective: to analyze the occurrence of violence in the elderly and its determinants in Betim, Minas Gerais. Method: A cross-sectional study, consisting of a population survey conducted through structured interviews. The sample was stratified by clusters in three stages: census tracts, households and the respondent. At the end, 1,129 households were visited, with the participation of 200 elderly people. The selection of the census tracts and domiciles was carried out electronically through the Statistical Package for Social Science (SPSS) version 20.0 and the selection of the respondent subject in the household occurred according to the Kish methodology, which recommends the random selection of a sample unit in a household. Initially, the data were analyzed by the Chi-square test, bivariate analysis and Correspondence Analysis. Subsequently, a logistic discriminant analysis was performed to explore the structure of relationships between dependent variables (violence in the elderly) and independent variables. Results: The most prevalent forms of violence were: lack of access to social rights (31%) followed by verbal (22%), moral / psychological (19%), lack of necessary care (16%); physical (6%), sexual (3%) and discrimination (3%). Men who suffered violence were not dependent, kept control of their money, and had a spouse. In the women, a greater number of dependents were found, who did not have control of their money, with education> 4th grade, without a spouse and with a high degree of depressive symptoms. The association considered strong refers to the elderly women who suffered violence and had their money used by another person and who suffered verbal violence. Conclusion: this study allowed reaffirming the profile of the elderly victim of violence through the analysis of their occurrence and its associated factors. The financial abuse factors and being victims of verbal violence were strongly associated with violence in the elderly - a result that sets a new look for these factors, since in Brazil, the main associated factors described previously were low educational levels, cognitive factors, dependence functional and depression. From the point of view of research for action, this research brings direct implication to the sectors interested in coping with the problem of violence in the elderly, especially for health professionals, since it shows that violence is part of a cycle that usually has factors characteristic associates that are part of a model nested mainly in the family relationship. Our expectation is that the silence of the elderly, victim of violence, serves to sharpen the listening of health professionals and that the determinants described here are seen as triggers for the detection and prevention of new cases. Finally, it should be pointed out that the study of violence in the elderly now demands that their findings are subsidiary to the health practice, conferring new strategies and methods for the culture of peace and non-violence.
