FEEDING AND DIABETES MELLITUS: PERCEPTION AND FOOD CONSUMPTION BY ELDERLY PEOPLE IN THE HINTERLANDS OF PERNAMBUCO

Objective: To evaluate the knowledge of diabetes diet and identify factors that may interfere with the adherence to nutritional therapy and food choices of participants in a Community Center for the Elderly in Sairé, PE. Methods: A quantitative, descriptive and cross-sectional study, which evaluated 39 attendees of that center, from July to August 2014, with or without diabetes mellitus. Two questionnaires were applied to assess socioeconomic data, nutrition knowledge and cultural factors, and check the consumption of food with high and low glycemic index. Data was analyzed using the Assistat Program 7.0 Beta version. Results: The majority of the respondents have knowledge about types of foods that may influence the treatment of diabetes mellitus, as 51.2% (n=20) reported knowing some food that can reduce the risk for diabetes onset or assist in its treatment. Most of the participants reported having acquired such knowledge through the television 35% (n=7) and conversation with peers 35% (n=7). Evaluation of the food intake evidenced higher consumption of foods with high glycemic index. However, among diabetic patients, foods with low glycemic index are consumed more times per week. Conclusion: The knowledge about nutrition and diabetes mellitus was considered adequate, but socioeconomic and cultural factors may interfere in the adherence to diet therapy for diabetes or in the food choices made by the individuals. However, food consumption was considered appropriate among diabetics.

CCR2 and CCR5 genes polymorphisms in women with cervical lesions from Pernambuco, Northeast Region of Brazil: a case-control study

Polymorphisms in chemokine receptors play an important role in the progression of cervical intraepithelial neoplasia (CIN) to cervical cancer (CC). Our study examined the association of CCR2-64I (rs1799864) and CCR5-Δ32 (rs333) polymorphisms with susceptibility to develop cervical lesion (CIN and CC) in a Brazilian population. The genotyping of 139 women with cervical lesions and 151 women without cervical lesions for the CCR2-64I and CCR5-Δ32 polymorphisms were performed using polymerase chain reaction-restriction fragment length polymorphism. The individuals carrying heterozygous or homozygous genotypes (GA+AA) for CCR2-64I polymorphisms seem to be at lower risk for cervical lesion [odds ratio (OR) = 0.37, p = 0.0008)]. The same was observed for the A allele (OR = 0.39, p = 0.0002), while no association was detected (p > 0.05) with CCR5-Δ32 polymorphism. Regarding the human papillomavirus (HPV) type, patients carrying the CCR2-64I polymorphism were protected against infection by HPV type 16 (OR = 0.35, p = 0.0184). In summary, our study showed a protective effect of CCR2-64I rs1799864 polymorphism against the development of cervical lesions (CIN and CC) and in the susceptibility of HPV 16 infection.

Investigation of H19/RsaI Polymorphism in Children With Low Birth Weight in Pernambuco, Brazil

Background: H19 is a strong candidate gene for influencing birth weight variation and is exclusively imprinted maternally. In an attempt to understand the relationship of this gene polymorphism with low birth weight children, we investigated association of H19/RsaI polymorphism with low birth weight and normal birth weight in children and their mothers. Objectives: The aim of our study was to establish the association between H19 gene polymorphism and LW in children born in Pernambuco, state of Brazil. Patients and Methods: It were selected 89 children, 40 low birth weight (LW) and 49 normal birth weight (NW) and 71 mothers (40 mothers of newborns NW and 31 mothers of newborns LW) attended at Dom Malan Hospital, Petrolina, Pernambuco - Brazil. Peripheral blood samples were collected from patients and genomic DNA was extracted and detected by electrophoresis agarose gel, stained by Blue Green Loading Dye. DNA PCR amplification was done using the primers H1 (sense) and H3 (antisense). PCR products were digested with RsaI and electrophoresed on agarose gel stained by ethidium bromide. Statistical analyses were performed using the program BioEstat version 5.0. Results: The RsaI polymorphism in the H19 gene showed that genotype frequencies did not differ statistically between low birth weight (AA = 12.5%, AB = 45%, BB = 42.5%) and control (AA = 8.6% AB = 36.73%, BB= 55.10% groups) and the allele frequencies were not significantly different (P = 0.2897). We also did not observe any association between maternal H19 allele polymorphism and low birth weight newborns (P =0.7799) or normal birth weight children (P = 0.8976). Conclusions: The small size of sample may be the explanation for these results; future studies with more patients are needed to confirm the effect of H19/RsaI polymorphism on birth weight of LW newborns.

IDEATIONAL REPRESENTATIONS OF EDENTULISM AND PROSTHETIC REHABILITATION FROM THE POINT OF VIEW OF THE ELDERLY

Objetivo: Identificar as representações ideativas de idosos edêntulos uni ou bimaxilares acerca das perdas dentárias e da reabilitação protética oral. Métodos: Estudo qualitativo, realizado entre janeiro e março de 2011 com sete idosos residentes em uma Instituição Pública de Longa Permanência do Recife-PE, com 14 idosos em atendimento na Clínica de Prótese Dentária da Universidade Federal de Pernambuco (UFPE). Coletaram-se os dados através de uma entrevista semiestruturada que passou por análise de conteúdo. Resultados: Os achados possibilitaram identificar que, para os idosos, os dentes contribuíam tanto para a saúde quanto como para facilitar interações sociais, enquanto o edentulismo foi associado a uma pluralidade de sentimentos negativos. Quanto à reabilitação protética, eles enfatizaram os prejuízos para a saúde devido a próteses mal adaptadas. Conclusão: Os idosos acreditam que o edentulismo e a reabilitação protética estão associados, principalmente, a um conceito mecanicista da profissão, amplamente difundido entre os profissionais que privilegiam mais a odontologia curativa em detrimento da prevenção. Nesse contexto, para que o envelhecimento possa ser considerado uma etapa da vida com as mesmas qualidades e dificuldades de qualquer outra, sugere-se aos gestores e aos próprios profissionais em saúde que se comprometam mais com uma prática odontológica humanizadora e preventiva, a fim de proverem os requisitos mínimos para um envelhecimento com dignidade.

DINÂMICA DA REGENERAÇÃO NATURAL NO SUB-BOSQUE DE Pinus caribaea Morelet. var. caribaea NA RESERVA BIOLÓGICA DE SALTINHO, TAMANDARÉ - PE

O estudo da estrutura e dinâmica da regeneração natural em sub-bosque de plantios com espécies exóticas, como as do gênero Pinus , possibilita dar informações para manejo, conservação e reestabelecimento das espécies nativas de uma comunidade vegetal. O objetivo deste trabalho foi identificar e quantificar a dinâmica da regeneração natural das espécies arbustivo-arbóreas ocorrentes no sub-bosque do povoamento de Pinus caribaea , na Rebio de Saltinho, em Pernambuco. Foram medidas as espécies regenerantes de 10 parcelas permanentes, de 1 x 50 m, e incluídos os indivíduos com circunferência na base a 30 cm do solo (CAB 0,30m) ≤ 15 cm e altura superior a um metro. A altura foi classificada em: Classe 1, indivíduos arbustivoarbóreos, com altura 1 ≤ H ≤ 2; Classe 2 com altura 2 < H ≤ 3; e Classe 3, com altura > 3 m e CAP ≤ 15 cm. Calcularam-se os parâmetros fitossociológicos, a dinâmica da regeneração e os índices de Shannon (H’) e a equabilidade (J’) por Pielou. Protium heptaphyllum teve maior número de indivíduos e valor de importância (VI), e Miconia prasina a melhor frequência nos dois levantamentos. Quanto ao índice H’ de 3,32 nats.ind-1 (2007) passou a 3,07 nats.ind-1 (2012), e a equabilidade de J’ de 0,85 a 0,62, havendo decréscimo tanto para a diversidade, quanto para a distribuição. O levantamento de 2012 registrou aumento de 12,5% do número de indivíduos, e os regenerantes de 2007 tiveram 48,31% de mortalidade. Com relação ao número de indivíduos e área basal, os percentuais de ganhos foram superiores ao das perdas. Conclui-se que a sucessão ecológica da regeneração do sub-bosque do povoamento estudado, encontra-se em modificação positiva, e o povoamento de Pinus caribaea, não está impedindo o surgimento de novos indivíduos e espécies.
