title: Implications of oral health in the functional area of elderly brazilians

description: Abstract Objective The objective of this study was to identify factors with a high degree of association with functional difficulty (DF) in the Brazilian elderly population, through the National Health Survey (PNS-2013). Material and method A cross-sectional, quantitative study with a data source from the PNS-2013, considering the total sample of individuals aged 60 or over (n = 23,815). For the analysis, two dependent variables were considered: Basic Activities of Daily Living and Instrumental Activities of Daily Living, and 30 independent variables related to sociodemographic and oral health conditions. The Waikato Environment for Knowledge Analysis software was used to perform the analyzes. Initially, the data set was balanced and the dimensionality reduction test was carried out, using the 10 Fold cross validation method. Finally, the variables related to the dependent variables were evaluated through logistic regression. Result The results point to the direct association between the DF of the elderly with: age aspects mainly for octogenarians (ABVD OR = 2.19 and AIVD OR = 2.82) and later, elderly without schooling (AIVD OR = 1.96), those who did not (AIVD OR = 1.65), and aspects of oral health, such as: presence of difficulty to feed due to problems with teeth or prostheses (ABVD OR = 1.73 and AIVD OR = 1.59), non-consultation with a dental surgeon throughout life (ABVD OR = 1.69) and absence of natural teeth (AIVD OR = 1.64). Conclusion Based on the findings, the importance of the strengthening of preventive strategies directed at the portion of individuals with 60 or more years, including oral health, is emphasized.

title: The Hydroclimatological Behavior of the Brazilian State of Rio Grande do Norte and the Municipality of Caicó

description: Abstract The aim of this article is to analyze rainfall patterns in the Brazilian state of Rio Grande do Norte and the municipality of Caicó with the objective of providing inputs to support local water resource management in view of the frequent water shortages in the state and the municipality. The data used for this purpose were annual accumulated precipitation data from all the municipalities in the state (1963-2013) from the SUDENE and EMPARN databases, and precipitation, evaporation, and evapotranspiration data on Caicó (1996-2013) from the INMET database. For the hydroclimatological analysis, other research on the subject was consulted, the quartile coefficient of dispersion and redistribution coefficient were used in the statistical and geospatial analyses, and the aridity index was calculated. The results of the spatial analyses were plotted on maps using ArcGis 10.0. The data showed that there is a spatial pattern of rainfall in the state of Rio Grande do Norte, with the highest rainfall occurring along the east coast, followed by the west of the state, while the central part (including part of the north coast) is the driest. It was found that the spatial distribution of precipitation remained the same whether the year was dry or rainy, with the highest values always appearing along the east coast, followed by the west of the state and the mountainous areas of the sertão, and finally the central region. Caicó was classified as semi-arid and highly susceptible to desertification. In this municipality, potential evaporation was found to be about five times higher than precipitation on average each year, indicating just how vulnerable it is to water shortage.

title: Spatial dependency and correlation of properties of soil cultivated with oil palm, Elaeis guineensis, in agroforestry systems in the eastern Brazilian Amazon

description: ABSTRACT Geostatistics is a tool that can be used to produce maps with the distribution of nutrients essential for the development of plants. Therefore, the present study aimed to analyze the spatial variation in chemical attributes of soils under oil palm cultivation in agroforestry systems in the eastern Brazilian Amazon, and their spatial dependence pattern. Sixty spatially standardized and georeferenced soil samples were collected at each of three sampling sites (DU1, DU2, and DU3) at 0-20 cm depth. Evaluated soil chemical attributes were pH, Al3+, H+Al, K+, Ca2+, Mg2+, cation exchange capacity (CEC), P, and organic matter (OM). The spatial dependence of these variables was evaluated with a semivariogram analysis, adjusting three theoretical models (spherical, exponential, and Gaussian). Following analysis for spatial dependence structure, ordinary kriging was used to estimate the value of each attribute at non-sampled sites. Spatial correlation among the attributes was tested using cokriging of data spatial distribution. All variables showed spatial dependence, with the exception of pH, in one sampling site (DU3). Highest K+, Ca2+, Mg2+, and OM levels were found in the lower region of two sampling sites (DU1 and DU2). Highest levels of Al3+ and H+Al levels were observed in the lower region of sampling site DU3. Some variables were correlated, therefore cokriging proved to be efficient in estimating primary variables as a function of secondary variables. The evaluated attributes showed spatial dependence and correlation, indicating that geostatistics may contribute to the effective management of agroforestry systems with oil palm in the Amazon region.

title: INFLUENCE OF THE MEDIUM RIGIDITY ON THE PHOTOCHROMISM KINETICS OF METAL DITHIZONATES

description: The kinetics of photoisomerization and thermal back reaction of mercury(II) and zinc(II) dithizonates, M(HDz)2, were analyzed by photolysis assays in fluid solution and in poly(methyl methacrylate), PMMA, films. In fluid solution, the photo- and thermoisomerization of both complexes can be described by a single exponential function. The Zn(II) dithizonate exhibits rate constants three orders of magnitude greater than that for Hg(II) complex, which is attributed to the higher charge density of the Zn(II) cation. In PMMA films, the thermal back reaction of both complexes can only be described by bi-exponential functions. On this more rigid medium the rate constants are about one order of magnitude slower than the respective ones in fluid solution and the bi-exponential behavior is related to regions in the polymeric matrix with distinct free volumes. The rate constants for both photo- and thermoisomerization of Zn(HDz)2 in PMMA are reported for the first time and are compared with the well-studied Hg(II) analog. The experimental data provides insights on the role of the metal cation on the photocromic behavior in rigid media, which can lately contribute for technological applications.

title: Initial difficulties with breastfeeding technique and the impact on duration of exclusive breastfeeding

description: Abstract Objectives: the present study aimed to evaluate the influence of initial difficulties in breastfeeding on duration of exclusive breastfeeding. Methods: a prospective study with follow up of nursing mothers and their babies in the first six months of age. The studied population was randomly selected among the Brazilian public health system (SUS, Portuguese acronym) users in three hospitals. The breastfeeding observation protocol was used to collect initial data, which also included socio-demographic, prenatal assistance, delivery care, the postpartum period and the newborn variables. After hospital discharge, data were collected by phone. The multiple regression model was used for statistical analysis. Results: 175 mother-baby binomials were followed. Problems with breasts during the postpartum hospital stay (p= 0.030; OR=2.38; CI95%=1.02-5.48), maternal work outside home (p=0.027; OR=2.12; CI95%=1.03-4.31) and low maternal schooling level (p=0.017; OR=2.13; CI95%=1.10-4.06) were shown to be associated with the early interruption of exclusive breastfeeding before the child has completed 6 months of age. A family income lower than one minimum wage was a protective factor (p=0.048; OR=0.42; CI95%=0.17-0.97). Conclusions: socioeconomic aspects and difficulties in breastfeeding associated with problems with the puerperal breasts stood out as factors which restrict the duration of exclusive breastfeeding.

title: Severe Maternal Morbidity: post-traumatic suffering and social support

description: ABSTRACT Objective: To assess the relationship of post-traumatic stress symptoms and the perception of social support in women submitted to Severe Maternal Morbidity (SMM). Method: A prospective cohort study, with 549 women from public hospitals. The Impact of Events and Social Support scales were used. Results: Women with SMM were from the State countryside (p=0.046), with low schooling (p=0.039) and did not work (p&lt;0.001). They presented higher consumption of alcoholic beverages (p&lt;0.001), did not perform prenatal (p&lt;0.001), and were older (28.15 ± 28 years). Women with SMM had higher mean values of avoidance behavior (24.32, SD: 4.16), intrusive thinking (18.28, SD: 3.80), lower social support (0.11, SD: 0.001) with large effect size and lower social support satisfaction (0.69; SD: 0.19), with small effect size. Conclusion: SMM is a differential and negative factor for women’s mental health, and social support can favor their coping.

title: Vascular epiphyte biomass in a South Brazilian fragment of Atlantic Forest

description: Abstract The present study aimed at sampling the biomass of vascular epiphytes within a protected area in South Brazilian Atlantic Forest. All tree specimens with diameter at breast height equal or greater than 4.8 cm were measured and divided into classes. In each class, 10% of tree specimens were randomly selected for epiphytic biomass measuring. Furthermore, we divided the phorophytes into five tree parts to analyze epiphytic biomass. We generated mathematical models to estimate epiphytic biomass in similar forest areas. We analyzed 55 phorophytes and found an estimated epiphytic biomass of 5.3 Mg/ha. Epiphytic biomass ranged from 0.02 to 135 kg and the lower values were found on small-sized phorophytes. Higher values of epiphytic biomass were found on phorophytes with diameter at breast height between 30 and 36.5 cm. The tree part with higher epiphytic biomass was the outer crown. The epiphytic biomass showed a high correlation with phorophyte diameter, according to the mathematical models. We selected two equations which presented the most similar values to the ones we measured. Our results corroborate that epiphytes play a very important role as to the biomass level within tropical forests.

title: Mother-to-child transmission of HIV in the Southern Region of Santa Catarina, from 2005 to 2015: analysis of risk factors to seroconversion in newborns

description: Abstract Objectives: to analyze both frequency and risk factors for seroconversion among newborns of HIV-positive mothers to HIV. Methods: a cohort study was conducted with children residing in Southern Region of Santa Catarina. Secondary data from the notification files and medical records of newborn's mothers of infected infants were used. The participants were all the newborns from 2005 to 2015 that were exposed to HIV through vertical transmission and attended a municipal health care center. Results: there were 104 cases of infant exposure to HIV. Seroconversion was confirmed in three cases, two of them died of AIDS during the study period. Breastfeeding (PR= 32.7; CI95%= 10.7-99.5; p= 0.002) and non-use of antiretroviral drugs during pregnancy (PR=18.2; CI95%= 2.0-163.0; p= 0.008) were risk factors for HIV seroconversion. Conclusions: seroconversion rates among neonates in Southern Region of Santa Catarina were similar to the national average. Seroconversion was associated with non-use of antiretroviral therapy during pregnancy and breastfeeding.

title: Analysis of the influence of column reinforcement anchorage length in a concrete two-pile cap

description: Abstract This paper describes the parametric analysis applied to assess the influence of column anchorage-reinforcement length on concrete two-pile caps under uniform compression. The non-linear numerical analysis was conducted with the bi-dimensional elements of ATENA 2D software, considering perfect adherence between steel and concrete. Simulation was based on the experimental reference model by Munhoz [1], which was the parameter adopted to validate the numerical modeling. From the validated model, four different anchorage reinforcement lengths were adopted, 34,0 cm, 20,0 cm, 10,0 cm e 3,0 cm, in order to compare pile caps behavior after these changes. Pile cap simulations presented similar behavior, i.e., column anchorage reinforcement length is not a preponderant factor for the internal mechanisms that regulate the function of these elements.

title: Risk-Benefit Assessment of Carotid Revascularization

description: Abstract Severe carotid atherosclerotic disease is responsible for 14% of all strokes, which result in a high rate of morbidity and mortality. In recent years, advances in clinical treatment of cardiovascular diseases have resulted in a significant decrease in mortality due to these causes. To review the main studies on carotid revascularization, evaluating the relationship between risks and benefits of this procedure. The data reviewed show that, for a net benefit, carotid intervention should only be performed in cases of a periprocedural risk of less than 6% in symptomatic patients. The medical therapy significantly reduced the revascularization net benefit ratio for stroke prevention in asymptomatic patients. Real life registries indicate that carotid stenting is associated with a greater periprocedural risk. The operator annual procedure volume and patient age has an important influence in the rate of stroke and death after carotid stenting. Symptomatic patients have a higher incidence of death and stroke after the procedure. Revascularization has the greatest benefit in the first weeks of the event. There is a discrepancy in the scientific literature about carotid revascularization and/or clinical treatment, both in primary and secondary prevention of patients with carotid artery injury. The identification of patients who will really benefit is a dynamic process subject to constant review.
