title: Analysis on the risk factors for organ damage in patients with systemic lupus erythematosus: a cross-sectional single-center experience

description: ABSTRACT BACKGROUND: Organ damage in patients with systemic lupus erythematosus (SLE) occurs as a consequence of the disease itself, the therapy applied and the accompanying conditions and complications. Organ damage predicts further organ damage and is associated with an increased risk of death. OBJECTIVE: This study aimed to assess the degree of irreversible organ changes in SLE patients, using the Systemic Lupus International Collaborating Clinics/American College of Rheumatology (SLICC/ACR) damage index (SDI); to establish correlations between organ damage and disease activity, quality of life, intensity of fatigue and serological factors; and to ascertain the risk factors for organ damage. DESIGN AND SETTING: Cross-sectional single-center study conducted at the Institute for Treatment and Rehabilitation “Niška Banja”, Niš, Serbia. METHODS: 83 patients with SLE were enrolled: 58 patients formed the group with organ damage (SDI ≥ 1), and 25 patients without organ damage served as controls (SDI = 0). RESULTS: Organ damage correlated with age (P = 0.002), disease duration (P = 0.015), disease activity (grade 1, P = 0.014; and grade 2, P = 0.007), poor quality of life, severe fatigue (P = 0.047) and treatment with azathioprine (P = 0.037). The following factors were protective: use of hydroxychloroquine (P = 0.048) and higher scores obtained for the physical (P = 0.011), mental (P = 0.022) and general health (P = 0.008) domains. CONCLUSION: It is very important to evaluate risk factors for organ damage in the body, including physicians’ overall assessment, to try to positively influence better treatment outcomes.

title: Effect of Glass Fiber Post Adaptation on Push-Out Bond Strength to Root Dentin

description: Abstract The aim of this study was to evaluate the effect of different glass fiber posts (GFPs) diameters on the push-out bond strength to dentin. Forty unirradicular human teeth were endodontically treated and used for cementation of GFPs (White Post DC, FGM) with different diameters (n=10): P1 - ø 1.6 mm coronal x 0.85 mm apical; P2 - ø 1.8 mm coronal x 1.05 mm apical; P5 - ø 1.4 mm coronal x 0.65 mm apical; and PC - customized post number 0.5 with composite resin (Tetric Ceram A2, Ivoclair Vivadent). All GFPs were cemented into the root canal using a dual-curing luting composite (Variolink II, Ivoclar Vivadent). One slice (1.7 mm) of each root third of cemented GFP (cervical, middle, and apical) was submitted to push-out testing. Failure modes of all specimens were classified as: adhesive failure between resin cement and post; adhesive failure between dentin and resin cement; cohesive failure within resin cement, post or dentin; and mixed failure. The data were analyzed with two-way ANOVA and Tukey’s test (a=0.05). The highest bond strength values were presented for the P2 and PC groups. There was no statistically significant difference between the GFP thirds in each group. The groups P2, P5, and PC showed predominantly adhesive failure. For P1, the most prevalent type of failure was adhesive between resin cement and post. It may be concluded that a glass fiber post that is well adapted to the root canal presents higher bond strength values, regardless of GFP third.

title: Farm size and TFP Growth in the Southeast region, from 1985 to 2006

description: Abstract The aim of this paper is to measure the Total Factor Productivity (TFP) growth by farm size in Southeast, from 1985, 1995/96 and 2006 agricultural census, as well as to decompose TFP change into its components, technological change and technical efficiency change. The methodology is based on stochastic frontier analysis. Data is aggregated at the municipality level into five size classes: 0-5 ha, 5-20 ha, 20-100 ha, 100-500 ha, and 500 ha and above. It was observed TFP growth in the Southeast; however, it was heterogeneous across size classes. The last size classes, of 100-500 ha and above 500 ha, achieved higher TFP growth than the first three classes (0-5 ha, 5-20 ha and 20-100 ha). However, all size classes had technical inefficiency increased.

title: Ovarian development and spawning of Macrobrachium amazonicum (Crustacea, Decapoda)

description: ABSTRACT Macrobrachium amazonicum (Heller, 1862) is the most important species for aquaculture native to South America. This study evaluates the phenotypic plasticity of females of Macrobrachium amazonicum with respect to the gonadal development, and determines the spawning type. Our study consisted of macro and microscopic analysis of the reproductive tract. Ovaries exhibited the following reproductive cells in developmental sequence: oogonia (OO) - mean diameter and standard deviation of 25.4 ± 6.5 μm; previtellogenic oocyte (PVO) - 61.7 ± 10.7 μm, vitellogenic oocyte (VO) - 113.9 ± 24.5 μm; and mature oocyte (MO) - 308.7 ± 56.3 μm. Ovaries increased in volume due to vitellogenesis and changing of basophilic to acidophilic composition. Follicular cells, atresic oocytes and postovulatory follicles were also analyzed. By combining macro and microscopic analysis, the ovaries of M. amazonicum were classified into six stages: Immature, In maturation, Mature, Spawned in maturation, Spawned and Resting. The ovarian development of M. amazonicum followed a standard pattern even among different populations. Considering our results and the evidence in literature, we conclude that spawning for this species is parceled or multiple, that is, synchronous in more than two groups (clutches of oocytes). Such observations provide basis for further studies addressing sustainable management strategies for species conservation and contribute to elucidate the biology of their specimens.

title: Factors associated with unfavorable outcomes caused by Syphilis infection in pregnancy

description: Abstract Objective: to analyze factors associated with unfavorable outcomes caused by syphilis infection in pregnancy. Methods: descriptive study carried out from May to August 2014, in public maternity hospitals. A questionnaire was administered to all women with a reactive Venereal Disease Research Laboratory (VDRL) test result and the data were supplemented with information from medical records and prenatal files. The bivariate analysis was performed using Pearson's chi-square or Fisher's exact test. For the multivariate analysis, was used through the logistic regression model. Results: a total of 137 puerperal women participated in the study, of which 14.3% had an unfavorable outcome, namely: stillbirth (2.9%), preterm birth (8.8%) and low birth weight (2.9%). In the multivariate analysis the odds ratio for the prevalence of an unfavorable outcome was three-fold higher in women who did not undergo a second VDRL test (OR=3,54; IC95% 1,04-15,33) and two-fold higher in women with a VDRL titer &gt;1:8 (OR=2,15; IC95% 1,11-11,2). Conclusions: The unfavorable outcomes occurred in women who did not undergo the second VDRL test and those whose VDRL titer was &gt;1:8 performed in the maternity hospital.

title: Alticini (Coleoptera, Chrysomelidae, Galerucinae) assemblage in forests fragments in Southwestern Paraná, Brazil

description: ABSTRACT Alticini is the largest tribe of Chrysomelidae and represents a large amount of the phytophagous insects’ fauna. However, the knowledge of this tribe in the southwest of Paraná is inexistent and, in this study, we aimed to seek information about the richness, abundance, diversity and composition of the assemblages in this region. The study was carried out weekly from October/2016 to March/2017 in forest fragments in the municipalities of Planalto, Realeza and Santa Izabel do Oeste, where Malaise traps were used. A total of 1,657 individuals of Alticini were collected, distributed in 20 genera and 59 species, with the majority of them showing few individuals. The most abundant species were Trichaltica sp. 2, Margaridisa sp., Omophoita octoguttata and Epitrix sp. 1, corresponding to 85.8% of all Alticini sampled. Margaridisa sp. was the dominant species in the fragments of Santa Izabel do Oeste and Realeza. Trichaltica sp. 2 was collected only in the Planalto fragment. Regarding to the species composition, the similarity was low, and only four species were shared among all fragments. This was the first survey developed in southwest Paraná, which contributed to knowledge of Alticini species in this region.

title: IMPACT OF PHYSICAL ACTIVITY CORRELATES IN THE ISOLATED AND COMBINED PRESENCE OF INSUFFICIENT LEVEL OF PHYSICAL ACTIVITY AND HIGH SCREEN TIME AMONG ADOLESCENTS

description: ABSTRACT Objective: To identify the impact of physical activity correlates with the isolated and combined presence of insufficient physical activity and high screen time among adolescents. Methods: A cross-sectional representative study was carried out with a sample of 786 adolescents (16.0±1.0 years; 53.9% girls) randomly selected in the schools of São José dos Pinhais, Paraná, Southern Brazil. The physical activity correlates analyzed were sex, nutritional status, economic class and sexual maturation. Physical activity level and screen time were measured and classified according to reference criteria. The associations were tested with Poisson regression and the population attributable fraction (PAF) verified the impact of correlates on the combined presence of insufficient level of physical activity and high screen time by the prevalence ratio (PR). Results: Among the studied adolescents, 84.7% (n=666) were considered insufficiently active, 96.4% (n=758) reported high screen time and 82.1% (n=645) presented the combined presence of these behaviors. The female sex and the high economic status were positively associated with the insufficient level of physical activity (PR=1.19; 95% confidence interval - 95%CI 1.12-1.27; PAF=15.97 - female/adjusted; PR=1,1; 95%CI 1,01-1,19; PAF=9,09 - high/adjusted class). The female sex also was positively associated to high screen time after adjustments (PR=1.18; 95%CI 1.10-1.27; PAF=15.25). The female sex was positively associated with the combined presence of these behaviors (PR=1.18; 95%CI 1.10-1.27) with a 15.25% impact on these behaviors. Conclusions: Physical activity correlates can have an impact on the insufficient level of physical activity and high screen time, especially among girls.

title: PREPARATION AND CHARACTERIZATION OF THIN-FILM COMPOSITE REVERSE OSMOSIS MEMBRANE ON A NOVEL AMINOSILANE-MODIFIED POLYVINYL CHLORIDE SUPPORT

description: ABSTRACT Herein, the influence of pure and modified polyvinyl chloride (PVC) support layers on the performance of thin-film composite (TFC) membranes was investigated in water desalination. Accordingly, the PVC support was modified using (3-Aminopropyl) triethoxysilane (APTES) through bulk modification. The supports were synthesized at different doses of APTES (0-6 wt%) and characterized with various analytical techniques. The results showed that APTES affected considerably both the morphology and surface properties of the support layer. Afterwards, the polyamide (PA) layer was formed via an identical interfacial polymerization (IP). The separation experiments showed that modification of the support improved the performance of the TFC membranes, which stems from the improvement in the degree of cross-linking of the PVC structure. At an appropriate condition, permeate fluxes were 0.89 L.m-2.h-1.bar-1 and 2.70 L.m-2.h-1.bar-1for TFC membranes with pure and modified PVC support layers, respectively. Interestingly, there were no significant changes in salt rejection of the prepared membranes.

title: Temporal variations of larval digenean assemblages parasitizing Heleobia parchappii (Mollusca: Cochliopidae) in two shallow lakes from the Buenos Aires province, Argentina

description: ABSTRACT The larval digenean assemblages in snail hosts are influenced by biotic and abiotic factors and by environmental disturbances due to human activities. Given their susceptibility to different types of impact, they can be useful tools for the study of temporal variations in parasite communities. The study of temporal dynamics in prevalence and species richness of larval digenean assemblages of Heleobia parchappii (D’Orbigny, 1835), in two Pampean lakes, provides a good opportunity to test the supposition that seasonal variations in digenean assemblages are determined by a series of biotic and abiotic factors that operate interdependently. To analyze the temporal variations, and to evaluate how local factors influence these digenean assemblages in Los Padres and La Brava lakes (Buenos Aires province, Argentina), 2,400 specimens of H. parchappii were collected seasonally, during one year. The digenean assemblages in Los Padres and La Brava lakes were composed of 13 and 12 species respectively. These larval digenean assemblages showed similarities in the number and in the seasonal frequency of occurrence of species (eight of which were present in both lakes). However, despite these similarities, the assemblages showed different temporal dynamics in La Brava and Los Padres lakes and, also, different correlations with the abiotic and biotic factors analyzed during this study (temperature, high of the water column and snail relative abundance). Temporal dynamics in prevalence and species richness of larval digenean assemblages of H. parchappii in both lakes seems to be influenced by a series of factors (diversity and abundance of definitive hosts, intermediate and definitive host location, snail relative abundance and anthropogenic disturbances). Our results highlight the importance of analyzing the role and interaction of local factors, especially in studies dealing with spatiotemporal fluctuations or with distance decay of similarities in species richness of parasite assemblages.

title: The Relationship between Lifestyle and Costs Related to Medicine Use in Adults

description: Abstract Background: The unhealthy lifestyle is growing and this can have repercussions on health status demanding actions on the occurrence of diseases and leads to increased expenses. Objective: To examine the interrelationship between the costs of medicine use and lifestyle behaviors. Methods: A cohort study with 118 participants, age around 51.7 ± 7.1 years old. It was collected personal and anthropometric data and information about medicine of continuous use to calculate the costs. Lifestyle variables included habitual physical activity (PA) assessed by pedometer, sedentary behavior by Baecke questionnaire, sleep quality by mini sleep questionnaire and self-report of smoke and alcohol consumption. Statistical analyses were performed by BioEstat (version 5.2) and the significance level set at p-value &lt; 0.05. Results: In 12 months, 62 subjects bought 172 medicines, representing an overall cost of US$ 3,087.01. Expenditures with drugs were negatively related to PA (r = -0.194, p-value = 0.035 and r = -0.281, p-value = 0.002), but positively related with sleep quality (r = 0.299, p-value=0.001 and r = 0.315, p-value = 0.001) and age (r = 0.274, p-value = 0.003). Four multivariate models were executed considering lifestyle behaviors in different moments of cohort and medicine costs, and all these models identify important relationship between lifestyle behaviors with expenditures with drugs. Conclusion: Worse sleep quality seems to increase the costs related to medicine use in adults, while obesity and ageing play a relevant role in this phenomenon and alcohol consumption seems a variable with relevant economic impact.
