Deterioração físico-conservacionista da sub - bacia hidrográfica do Rio Ibicuí-Mirim - RS

O presente trabalho trata do diagnostico da deterioracao fisico-conservacionista realizado na Sub-bacia hidrografica do Rio Ibicui-Mirim, localizado no estado do Rio Grande do Sul. Em uma area que corresponde a 8.882,50 ha e foi dividida em 49 microbacias. A metodologia consistiu em determinar o coeficiente de rugosidade (RN), a partir das caracteristicas fisicas das microbacias e utiliza-lo para a distribuicao das classes de aptidao de uso da terra. O diagnostico da area mostrou que o nivel de deterioracao fisico-ambiental na Sub-bacia do Rio Ibicui-Mirim e de 30,16%. O estudo da aptidao do solo mostrou que 28,8% da area da sub-bacia tem vocacao florestal, 32,5% para agricultura/urbanizacao, 28,6% para pastagem/urbanizacao e 10,1% para pastagem/floresta.

Deterioração físico-conservacionista da microbacia hidrográfica do riacho Paus Brancos, Campina Grande, PB

The objective of the present study consisted in the diagnosis of the physical conservationist deterioration of the microbasin of the Paus Brancos Stream, Campina Grande, PB, in the semi-arid region of Paraiba state. The microbasin was divided in 11 minibasin. The methodology consisted in determination of the rugosity coefficient (Ruggdeness Number - RN), using the physical characteristics of the minibasins and the distribution of land use classes using the rugosity coefficient. In the studied area the physical conservationist deterioration is high (34.91%), contributing to this the small vegetable covering 232.15 ha (10.05%). There is availability of many areas for the agriculture but their utilization depends on auxiliary diagnosis. Although there are only 172.37 ha (7.48%) in conflicts, for the perfect environmental equilibrium of the microbasin, 1,286.14 ha (55.68%) need to be worked out. No class A minibasin presented excess of agricultural area. The deteriorated area in the studied microbasin is 507.35 ha (21.97%).

Zoneamento ambiental em Pantanais (Banhados)

The environmental zoning in swamp regions allowed the evaluation of the environmental deterioration of the ecosystems in the Ecological Station of Taim (ESEC/TAIM), in Rio Grande and Santa Vitoria of Palmar (in the State of Rio Grande do Sul - Brazil). Two different types of ecosystems were considered: swamp regions (ECO1 = Limnico Ecosystem) and the Marine Plain (ECO2 = Ecosystem Marine Plain). The ECOTOTAL (ECO1 + ECO2) presented 64% of the class APP (Permanent Preservation Area), 27.6% of ACP (Permanent Conservation Area), 5.6% of AUO (Occupation and Use Area), and in a smaller percentage the class AR (Restoration Area) with 2.8%. The environmental deterioration of ESEC/TAIM (ECOTOTAL) was 13.65%. The factorial analysis technique permitted the derivation of the structure of the data, showing the correlations among each variable (exuberance classes) and its respective factor, however this did not allow the separation of the groups or quantify the influence of one or more variables on another of interest (variable answer). It is recommended that the environmental zoning be elaborated by the environmental public organs in the other ecological stations and in the units of conservation.

Edema and gingival bleeding in anterior region have a negative influence on quality of life of adolescents

The aim of the present study was to verify if clinical signs of gingivitis such as color changes, edema, and bleeding in the anterior region influence the OHRQoL of adolescents. We followed a cross-sectional convenience sample of 67 adolescents aged 11 to 16 years receiving dental treatment at the Federal University of Santa Maria (UFSM), in southern Brazil. The participants were evaluated for the following clinical variables: edema, gingival color alteration, and marginal bleeding of the gingival tissues, collected at 6 sites per tooth in the anterior region of the mouth. Socioeconomic variables were collected through questionnaires and OHRQoL was evaluated through the Brazilian version of the Children Perception Questionnaire (CPQ 11-14) short form. A Poisson regression model was used to verify associations between clinical variables and general CPQ11-14 scores. In the unadjusted analysis, edema, color alterations, and marginal bleeding in the anterior region were associated with worse scores of OHRQoL. Edema and marginal bleeding remained associated after adjusting for clinical and sociodemographic variables. Adolescents with higher levels of marginal bleeding and edema in the anterior region had higher mean CPQ11-14 scores. Therefore, the presence of bleeding and gingival edema in the anterior region can be considered clinical signs of gingivitis that are associated with a worse OHRQoL in adolescents.

Oral health related quality of life among pregnant women: a randomized controlled trial.

The aim of the present study was to compare negative impacts of oral conditions in Oral Heath Related Quality of Life (OHRQoL) assessed by the Oral Health Impact Profile-14 (OHIP-14) scores in pregnant women receiving or not comprehensive periodontal treatment. This randomized controlled clinical trial included pregnant women aged between 18 and 35 years old. Participants were randomized in a test group with 96 and a control group with 114 women. Patients in the test group received comprehensive periodontal treatment, supra and subgingival scaling and root-planning and periodontal maintenance appointments. The OHIP-14 was applied before and after treatment. The primary outcome was changes in OHIP-14 scores after follow-up period. The impact of having received or not comprehensive periodontal treatment on the change of the OHIP-14 scores was also investigated. Both groups showed significant reduction in OHIP-14 scores and effect size for the test group was 0.60 and 0.36 for the control group. Multinomial logistic regression analysis showed that participants of the control group had 5.9-fold odds (CI 95% 1.88-18.52) of worsening in OHIP-14 scores and their perception of oral conditions in relation to test group. Comprehensive periodontal treatment during pregnancy can reduce the negative impacts in OHRQoL.
