Fusobacterium nucleatum and Prevotella in women with periodontitis and preterm birth.

BACKGROUND: Studies try to explain the hypothesis that maternal periodontitis may be associated with preterm birth. MATERIAL AND METHODS: This is a case-control study with 120, 40 cases (gestational age <37 weeks) and 80 controls (gestational age ≥37 weeks), that were submitted to the clinical periodontal examination and subgingival biofilm collection. Bacterial DNA of subgingival biofilm was performed and processed by qPCR. RESULTS: Periodontitis was statistically significant in the Case group (35%) when compared to the Control group (11.2%) and Gingival Bleeding Index (GBI), sites with PS ≥ 4mm and sites with CAL ≥ 5mm were statistically higher in the Case group (p < 0.05). The proportions of Pi (p = 0.026) and Fn (p = 0.041) of subgingival biofilm were higher in the Case group. A greater number of sites with PS ≥ 4mm (r = -0.202; p = 0.026) and CAL ≥ 5mm (r = -0.322; p < 0.001) were correlated to lower gestational age. CONCLUSIONS: Periodontitis, preterm delivery, and/or low birth weight may have a possible relationship based on clinical parameters and the ratio of Pi and Fn at periodontal sites.

Etnobotânica de plantas medicinais em duas comunidades do município de Picuí, Paraíba, Brasil / Ethnobotanic of medicinal plants in two communities in the municipality of Picuí, Paraíba, Brazil

RESUMO O presente trabalho realizou um levantamento etnobotânico sobre a utilização de plantas medicinais no município de Picuí, Seridó Oriental, Estado da Paraíba, Brasil. Foi analisada uma área urbana (bairro monte santo) e uma rural (sítio massapê). As informações etnobotânicas foram obtidas através de formulários semiestruturados, contendo características socioeconômicas dos entrevistados, características das plantas e seus usos terapêuticos. Para a entrevista foi selecionado o adulto responsável pela residência, “chefe de família”, e utilizou-se a técnica da “bola de neve”. Foram citadas 37 famílias botânicas, 59 gêneros e 64 espécies. As espécies mais citadas foram Vernonia condensata Baker e Chenopodium ambrosioides L. e a família mais indicada foi Fabaceae. O hábito predominante foi o herbáceo, seguido do arbóreo; as partes da planta mais utilizadas foram as folhas e as cascas do caule; os principais modos de preparo dos remédios foram os chás e a água e/ou sumo. A planta com maior CUPc foi Vernonia condensata Baker (41,67%), sendo também uma das plantas com maior FRt junto a Chenopodium ambrosioides L., ambas com 19,6%. Esses resultados demonstraram que as populações estudadas ainda usam plantas medicinais com frequência, entretanto, a maioria das plantas utilizadas não é nativa da caatinga.

ABSTRACT This study conducted an ethnobotanical survey on the use of medicinal plants in the municipality of Picuí, Seridó of Paraíba, Brazil. An urban area (neighborhood monte santo) and a rural area (massapê farm) were analysed. The ethnobotanical information was obtained through semi-structured questionary containing socioeconomic characteristics of the respondents, characteristics of plants and their therapeutic uses. We selected an adult which was the responsible adult of the residence “householder” for the interview and used the technique of “snowball”. 37 plant families, 59 genera and 64 species were cited. The species most frequently cited were Vernonia condensata Baker and Chenopodium ambrosioides L. and the most mentioned family was Fabaceae. The predominant habit was the herbaceous, followed by woody, the parts of the plant which were most used are the leaves and bark of the stem, the main modes of preparation of the medicines were showers and water and / or lushness. The plant with the highest CUPc was Vernonia condensata Baker (41.67%), and it was also one of the plants with greatest FRt along with Chenopodium ambrosioides L., both with 19.6%. These results demonstrated that the studied populations still use medicinal plants often, however, most of the plants used is not native to the caatinga.
