Fatores de risco da ulceração aftosa recorrente – uma revisão dos achados atuais

The Recurrent Aphthous Ulceration (RAU) is the most common oral mucosal disorder, attacking mainly non-keratinized areas. It is characterized by painful, recurring, superficial ulcers, surrounded by erythematous haloes. The ulcers are classified, according to clinical characteristics, as minor ulcers, major ulcers and herpetiform ulcers. Its etiology is multifactorial and can be associated with family history and local, systemic and genetic factors. The diagnosis is fundamentally made through anamnesis and clinical exam, because no laboratory procedures exisst to confirm the diagnosis. To date, there is no curative therapy to prevent the recurrence of ulcers, and all available treatment modalities can only reduce the frequency and severity of the lesions. Based in the actual findings, the main objective of this paper is to relate and discuss the main risk factors of the recurrent aphthous ulceration, found in the literature, and so it contributes for better understanding this disorder.A Ulceração Aftosa Recorrente (UAR) é a desordem que afeta a mucosa oral com maior freqüência, acometendo principalmente áreas não ceratinizadas. Caracteriza-se por ulcerações dolorosas, recorrentes, superficiais, circundadas por um halo eritematoso. As úlceras são classificadas de acordo com suas características clínicas em úlceras aftosas menores, úlceras aftosas maiores e úlceras herpetiformes. Sua etiologia é multifatorial, e podem estar associadas com histórico familiar, fatores locais, sistêmicos e genéticos. O diagnóstico é basicamente feito através de uma boa anamnese e um exame clínico, já que não existem exames laboratoriais que confirmem o diagnóstico. Até o momento, não existe tratamento curativo para prevenir a recorrência das ulcerações: todas as modalidades disponíveis podem apenas reduzir a freqüência e a severidade das lesões. Com base nos achados atuais, o objetivo do presente trabalho é relatar e discutir os principais fatores de risco da ulceração aftosa recorrente encontrados na literatura e, assim, colaborar para o melhor entendimento dessa desordem

Masticatory Function and Nutritional Status in Brazilian Institutionalized Elders: Influence of Denture Use

Objective: To evaluate the influence of tooth loss and the use of removable dentures on chewing function and nutritional status of institutionalized elders. Material and Methods: Cross-sectional study with 155 elders from seven long-stay institutions in João Pessoa, Brazil. The participants were classified according to the presence of reminiscent teeth and use of dentures in four levels: toothless, without denture (1); toothless with a complete denture (2); partial toothless without denture (3) and partial toothless with a partial denture (4). Nutritional status was assessed using the Mini-Nutritional Assessment (MNA) instrument and the Body Mass Index (BMI). Swallowing threshold was used for the assessment of masticatory function, using a portion of roasted peanuts (3.7 g). Comparisons among groups were performed using Kruskal-Wallis test with Bonferroni adjustment, considering p<0.05. Results: MNA (p=0.702) and BMI (p=0.884) were not modified in relation to the presence of teeth and denture use. Toothless individuals without dentures had a lower swallowing threshold (p<0.001), whilst partial toothless with dentures had better masticatory function (p>0.05). Conclusion: The presence of reminiscent teeth and the use of dentures do not influence the nutritional status of the elders but interfere with the masticatory function. Prosthetic rehabilitation is desirable for complete toothless individuals

Manejo do sobrepeso e obesidade em crianças e adolescentes por enfermeiras: estudo de métodos mistos

Objective: to analyze the management of overweight and obesity in children and adolescents by nurses of the Family Health Strategy. Method: this is a study of convergent parallel mixed methods, developed in Health Centers of a municipality in northeastern Brazil. In the quantitative stage, data were collected from a questionnaire applied to 98 nurses and analyzed by descriptive statistics. For the qualitative stage, semi-structured interviews were conducted with seven nurses, interpreted by inductive thematic analysis. The quantitative and qualitative results were integrated and presented by a joint display. Results: most nurses rarely checked waist circumference (77.6%), dyslipidemia (55.7%), blood glucose (42.3%), and neither evaluated blood pressure (75.3%). In the qualitative results, we identified that there are nurses who did not classify body mass index according to sex and age. As for medical tests, the requests were mainly related to the routine of childcare. Guidance on physical activity and diet were given in a basic way or attributed to other professionals, and referrals to other services or professionals were not followed up. Conclusion: it is imperative to train nurses for the management of overweight and obesity in primary care for children and adolescents, with a view to quality of care for the prevention of comorbidities.Objetivo: analisar o manejo do sobrepeso e da obesidade de crianças e adolescentes por enfermeiras da Estratégia Saúde da Família. Método: estudo de método misto paralelo convergente, desenvolvido em Unidades Básicas de Saúde, de um município do nordeste brasileiro. Na etapa quantitativa, os dados foram coletados a partir de um questionário aplicado a 98 enfermeiras e analisados por meio de estatística descritiva. Para a etapa qualitativa, foram realizadas entrevistas semiestruturadas com sete enfermeiras, interpretadas pela análise temática indutiva. Os resultados quantitativos e qualitativos foram integrados e apresentados por meio de joint display. Resultados: a maioria dos enfermeiros raramente verificava a circunferência da cintura (77,6%), dislipidemia (55,7%), glicemia (42,3%) e nenhum avaliava a pressão arterial (75,3%). Nos resultados qualitativos, identificamos que há enfermeiros que não classificavam o índice de massa corporal segundo sexo e idade. Quanto aos exames, as solicitações estavam relacionadas principalmente à rotina de puericultura. As orientações sobre atividade física e alimentação foram dadas de forma básica ou atribuídas a outros profissionais, e os encaminhamentos para outros serviços ou profissionais sem seguimento pelos enfermeiros. Conclusão: é imperioso a capacitação dos enfermeiros para o manejo do sobrepeso e obesidade na atenção primária para crianças e adolescentes com vistas a qualidade do atendimento para a prevenção de comorbidades.Objetivo: analizar el manejo del sobrepeso y la obesidad en niños y adolescentes por las enfermeras de la Estrategia Salud de la Familia (ESF). Método: se trata de un estudio de método mixto paralelo convergente, desarrollado en Centros de Salud (UBS) de un municipio del nordeste de Brasil En la etapa cuantitativa, los datos fueron recolectados a partir de un cuestionario aplicado a 98 enfermeras y evaluados mediante estadística descriptiva. Para la etapa cualitativa, se realizaron entrevistas semiestructuradas con siete enfermeras, interpretadas por análisis temático inductivo. Se combinaron los resultados cuantitativos y cualitativos y se mostraron a través de joint display. Resultados: la mayoría de los enfermeros raramente verificaba el perímetro de cintura (77,6%), la dislipidemia (55,7%), la glucemia (42,3%) y tampoco evaluaba la presión arterial (75,3%). En los resultados cualitativos se identificó que hay enfermeras que no clasificaban el índice de masa corporal según sexo y edad. En cuanto a la solicitación de pruebas, las peticiones se trataban principalmente sobre la rutina asociada a la puericultura. Las orientaciones con respecto a la actividad física y nutrición se efectuaban de forma básica o eran asignadas a otros profesionales, y también no se hizo un seguimiento cuando fueron direccionados a otros servicios o profesionales. Conclusión: existen deficiencias en el conocimiento y la práctica de las enfermeras de atención primaria en el control del sobrepeso y la obesidad en niños y adolescentes. Es imperativo capacitar a los enfermeros para el manejo del sobrepeso y la obesidad en la atención primaria de niños y adolescentes, con miras a la calidad de la atención para la prevención de comorbilidades

Wild dogs at stake: deforestation threatens the only Amazon endemic canid, the short-eared dog (Atelocynus microtis)

The persistent high deforestation rate and fragmentation of the Amazon forests are the main threats to their biodiversity. To anticipate and mitigate these threats, it is important to understand and predict how species respond to the rapidly changing landscape. The short-eared dog Atelocynus microtis is the only Amazon-endemic canid and one of the most understudied wild dogs worldwide. We investigated short-eared dog habitat associations on two spatial scales. First, we used the largest record database ever compiled for short-eared dogs in combination with species distribution models to map species habitat suitability, estimate its distribution range and predict shifts in species distribution in response to predicted deforestation across the entire Amazon (regional scale). Second, we used systematic camera trap surveys and occupancy models to investigate how forest cover and forest fragmentation affect the space use of this species in the Southern Brazilian Amazon (local scale). Species distribution models suggested that the short-eared dog potentially occurs over an extensive and continuous area, through most of the Amazon region south of the Amazon River. However, approximately 30% of the short-eared dog's current distribution is expected to be lost or suffer sharp declines in habitat suitability by 2027 (within three generations) due to forest loss. This proportion might reach 40% of the species distribution in unprotected areas and exceed 60% in some interfluves (i.e. portions of land separated by large rivers) of the Amazon basin. Our local-scale analysis indicated that the presence of forest positively affected short-eared dog space use, while the density of forest edges had a negative effect. Beyond shedding light on the ecology of the short-eared dog and refining its distribution range, our results stress that forest loss poses a serious threat to the conservation of the species in a short time frame. Hence, we propose a re-assessment of the short-eared dog's current IUCN Red List status (Near Threatened) based on findings presented here. Our study exemplifies how data can be integrated across sources and modelling procedures to improve our knowledge of relatively understudied species

Metabolically Healthy Obesity and High Carotid Intima-Media Thickness in Children and Adolescents: International Childhood Vascular Structure Evaluation Consortium

OBJECTIVE It has been argued that metabolically healthy obesity (MHO) does not increase cardiovascular disease (CVD) risk. This study examines the association of MHO with carotid intima-media thickness (cIMT), a proxy of CVD risk, in children and adolescents. RESEARCH DESIGN AND METHODS Data were available for 3,497 children and adolescents aged 6–17 years from five population-based cross-sectional studies in Brazil, China, Greece, Italy, and Spain. Weight status categories (normal, overweight, and obese) were defined using BMI cutoffs from the International Obesity Task Force. Metabolic status (defined as "healthy" [no risk factors] or "unhealthy" [one or more risk factors]) was based on four CVD risk factors: elevated blood pressure, elevated triglyceride levels, reduced HDL cholesterol, and elevated fasting glucose. High cIMT was defined as cIMT ≥90th percentile for sex, age, and study population. Logistic regression model was used to examine the association of weight and metabolic status with high cIMT, with adjustment for sex, age, race/ethnicity, and study center. RESULTS In comparison with metabolically healthy normal weight, odds ratios (ORs) for high cIMT were 2.29 (95% CI 1.58–3.32) for metabolically healthy overweight and 3.91 (2.46–6.21) for MHO. ORs for high cIMT were 1.44 (1.03–2.02) for unhealthy normal weight, 3.49 (2.51–4.85) for unhealthy overweight, and 6.96 (5.05–9.61) for unhealthy obesity. CONCLUSIONS Among children and adolescents, cIMT was higher for both MHO and metabolically healthy overweight compared with metabolically healthy normal weight. Our findings reinforce the need for weight control in children and adolescents irrespective of their metabolic status

ATLANTIC-PRIMATES: a dataset of communities and occurrences of primates in the Atlantic Forests of South America

Primates play an important role in ecosystem functioning and offer critical insights into human evolution, biology, behavior, and emerging infectious diseases. There are 26 primate species in the Atlantic Forests of South America, 19 of them endemic. We compiled a dataset of 5,472 georeferenced locations of 26 native and 1 introduced primate species, as hybrids in the genera Callithrix and Alouatta. The dataset includes 700 primate communities, 8,121 single species occurrences and 714 estimates of primate population sizes, covering most natural forest types of the tropical and subtropical Atlantic Forest of Brazil, Paraguay and Argentina and some other biomes. On average, primate communities of the Atlantic Forest harbor 2 ± 1 species (range = 1–6). However, about 40% of primate communities contain only one species. Alouatta guariba (N = 2,188 records) and Sapajus nigritus (N = 1,127) were the species with the most records. Callicebus barbarabrownae (N = 35), Leontopithecus caissara (N = 38), and Sapajus libidinosus (N = 41) were the species with the least records. Recorded primate densities varied from 0.004 individuals/km 2 (Alouatta guariba at Fragmento do Bugre, Paraná, Brazil) to 400 individuals/km 2 (Alouatta caraya in Santiago, Rio Grande do Sul, Brazil). Our dataset reflects disparity between the numerous primate census conducted in the Atlantic Forest, in contrast to the scarcity of estimates of population sizes and densities. With these data, researchers can develop different macroecological and regional level studies, focusing on communities, populations, species co-occurrence and distribution patterns. Moreover, the data can also be used to assess the consequences of fragmentation, defaunation, and disease outbreaks on different ecological processes, such as trophic cascades, species invasion or extinction, and community dynamics.
