Abstract: catfishes of the genus pseudoplatystoma are very important species due to both their high commercial value and their ecological role as voracious predators. they undertake lengthy migratory movements during their life-cycle, this including reproductive migration which occurs from october to december in the rainy season. in the present study, seven microsatellite loci were analyzed to access genetic variability in two samples of p. reticulatum from the upper paraguay basin. the loci were highly polymorphic (mean = 7.28). according to all analysis, the two samples of p. reticulatum revealed pronounced genetic differentiation. fst value was 0.2290, rst value 0.1067 and amova 22.90% (fst) and 10.67% (rst), all being highly significant (p < 0.001). the division of the fishes into two groups was confirmed by microsatellite multi-locus bayesian assignment testing. the results obtained present evidence of genetic structuring in a p. reticulatum population.
Effect of Massage Therapy in Cancer Patients  [PDF]
Marcia Alves, Maria Helena de Agrela Gon?alves Jardim, Bárbara Pereira Gomes

Abstract: The increase in longevity and incidence of chronic diseases reveals an increased importance in terms of public health. The oncologic illness is a debilitating and progressive pathology with need for prevention and symptomatic relief. In order to find the answer to the question: “What is the effect of massage therapy in cancer patients?” we have reviewed the empirical literature indexed in databases online, finding only 21 articles published between 1990 and 2015. It was possible to verify some of the effects of massage therapy, particularly in relieving pain, decreased anxiety, depression and nausea and increased well-being. However, it was not found the effect of this intervention on the relief of suffering and the quality of life of patients. With the heterogeneity of methodologies, studies suggest the development of more homogeneous research, materials and methods to assess the effects of massage therapy in cancer patients.

Abstract: The script fading procedure aims to develop better communication skills of children and youngsters with Autism Spectrum Disorder in relationship with other people. The procedure seeks to incorporate cues in several contexts. Scripts may be organized in day-to-day situations of life, such as playful interactions among children and the scripts may consist in pictorial, textual or auditory stimuli. If a learner, for example, lacks conversation skills, but has good repertoire regarding textual behavior, scripts consisting of written phrases may be presented and the learner has to read them. The listener may interact with the speaker like he is emitting responses free from the control of scripts. With repetitive exposure to the contingency and the establishment of a more fluent repertoire of textual behavior, the script is gradually faded out by word removal one by one. This process continues until the learner’s responses become free from the control of the whole scripts. Previous research has demonstrated the establishment of independent performance, maintenance and generalization to different settings and listeners. The purpose of this study was to assess the efficacy of this procedure in establishing conversation skills in a child aged 9 with ASD. Textual scripts were applied to three sets of conversation. After a baseline condition, training started and the experimental control by the independent variable was established through a multiple baseline design across the three different conversation topics. Independent performance was successfully established through reinforcement of correct performance and error correction. Although the interventions were conducted in a university-based laboratory, the established repertoires generalized to the child’s school classroom and another listeners (another adult and a child). Implications to school inclusion regarding the establishment of conversation among children in school setting were discussed.

Abstract: previous research has explored the impact of culture and socioeconomic status in risk-taking sexual behaviours by adolescents, but currently there are few qualitative studies about sex behaviour in early adolescence and there is little practice-based information concerning interventions designed to reduce risk-taking sexual behaviours, especially in adolescents of specific social environments. therefore, the main objectives of this investigation are t o understand and characterize risk and protective factors associated to sexuality of adolescents, seeking also a comparison of culture and economic status. a qualitative approach was used, in order to collect data (focus groups). various aspects of sexuality in early adolescence were explored . the results highlighted some characteristics of adolescents that belong to specific social environments (migrant or low socioeconomic status). they have less information, communicate less with their parents and have more risk-taking sex behaviour. these features are critical in order to promote a specific intervention in these groups.

Abstract: Introduction: shoulder joint has the greatest range of motion in the human body. The shoulder anatomy promotes high mobility and favors relative sacrifice of articular stability, making it susceptible and more prone to events of instability and dislocation. This review aimed at identifying main complications of surgical treatment of anterior shoulder dislocation. Methodology: This systematic review was conducted according to the International Preferred Reporting Items for Systematic Reviews and Meta-Analyzes (PRISMA) guidelines. Studies which were eligible for this systematic review included: English or Spanish language, studies published from 2000, which mentioned surgical complications of anterior shoulder dislocation in their results, both in open and arthroscopic surgery. Included studies which were required to have at least 1 complication following surgical repair. Only studies from original data were included. Results: We found 228 potentially eligible studies for the survey. Through the inclusion and exclusion criteria and after consensus among reviewers, we chose 9 studies to compose the systematic review. Conclusion: Important information emerges: recurring instability, recurring dislocation, external rotation limitation and arthritis are main surgical complications of anterior shoulder dislocation.

Abstract: Objectives: The purpose of this study was to evaluate and compare the use of propinox hydrochloride and scopolamine hydrochloride in patients presenting abdominal colic (abdominal pain), in terms of treatment efficacy and tolerability. Material & Methods: This was an analytical, retrospective, comparative study based on hospital records of outpatients treated at Serviço de Clínica Médica do Hospital das Clínicas Costantino Otaviano (HCTCO) and at Santa Casa de Misericórdia do Rio de Janeiro, from 1988-1998. Subjects were divided into two groups: patients from Group 1 were treated with propinox hydrochloride, while patients from Group 2 were treated with scopolamine hydrochloride. Statistical analysis was performed using GraphPad Prism version 5.0. For comparison of categorical variables, we used the chi-squared or Fisher’s test, while continuous variables were analyzed using ANOVA or the Student’s T test. Results: A total of 1042 subjects were included, of which 525 were allocated to Group 1 and 517 to Group 2. Mean treatment duration was 9.166 days (±4.208) in Group 1 and 8.795 days (±5.052) in Group 2, with no statistically significant difference in treatment duration between the two groups (p = 0.198). All subjects in Group 1 were treated with propinox 10 mg (2 coated tablets, three times per day) while all subjects in Group 2 were treated with scopolamine hydrochloride 10 mg (2 coated tablets, three times per day). There were no statistically significant between-group differences in weight, BMI, heart rate, and respiratory rate at pre- and post-treatment; with the exception of higher post-treatment systolic blood pressure in Group 1, blood pressure measures also remained homogenous. Adverse events were reported among both treatment groups with no significant between-group difference in incidence (p = 0566). At pretreatment, pain intensity was more severe in Group 1 (p = 0.0257), while at post-treatment, there was no statistically significant difference between the two treatment groups (p = 0.895). There was a statistically significant improvement in pain intensity within both treatment groups (χ2 = 631.4; df = 3; p < 0.0001 for Group 1 and χ2 = 554.3; df = 3; p < 0.0001 for Group 2). Conclusion: The results obtained in this study indicate a therapeutic equivalence between propinox hydrochloride and scopolamine hydrochloride. Both treatments demonstrated good efficacy and tolerability in the treatment of abdominal colic pain, in the population evaluated.

Abstract: coffee is one of the most appreciated drinks in the world. coffee ground is obtained from the fruit of a small plant that belongs to the genus coffea. coffea arabica and coffea canephora robusta are the two most commercially important species. they are more commonly known as arabica and robusta, respectively. two-thirds of coffea arabica plants are grown in south and central america, and eastern africa - the place of origin for this coffee species. contamination by microorganisms has been a major matter affecting coffee quality in brazil, mainly due to the harvesting method adopted. brazilian harvests are based on fruits collected from the ground mixed with those that fall on collection cloths. as the bacillus cereus bacterium frequently uses the soil as its environmental reservoir, it is easily capable of becoming a contaminant. this study aimed to evaluate the contamination and potential of b. cereus enterotoxin genes encoding the hbl and nhe complexes, which were observed in strains of ground and roasted coffee samples sold in rio de janeiro. the pcr (polymerase chain reaction) results revealed high potential of enterotoxin production in the samples. the method described by speck (1984) was used for the isolation of contaminants. the investigation of the potential production of enterotoxins through isolates of the microorganism was performed using the b. cereus enterotoxin reverse passive latex agglutination test-kit (bcet-rpla, oxoid), according to the manufacturer's instructions. the potential of enterotoxin production was investigated using polymerase chain reaction (pcr) methods for hbla, hbld and hblc genes (encoding hemolysin hbl) and for nhea, nheb and nhec genes (encoding non-hemolytic enterotoxin - nhe). of all the 17 strains, 100% were positive for at least 1 enterotoxin gene; 52.9% (9/17) were positive for the 3 genes encoding the hbl complex; 35.3% (6/17) were positive for the three nhe encoding genes; and 29.4% (5/17) were positive for all enterotoxi

Abstract: Introduction: There has been an increase in the proportion of cesarean deliveries, especially in developing countries. Methods: Cross-sectional study of all hospital live births from mothers living in Sao Paulo Metropolitan Area, Brazil. Data were obtained from the Live Birth Information System, which is linked to the National Database of Health Establishments. Hospitals were classified as public, private or mixed. Descriptive analysis and exponential regression were conducted to evaluate time trends. Poisson regression was applied to analyze each hospital type to identify risk factors and the attributable risk fraction for cesarean section. Results: There was an annual increase (1.4%) of cesarean deliveries between 2000 and2013. In2009, the percentage of cesarean deliveries was 53% overall and 83% in private hospitals. The primary risk factor for cesarean delivery was delivery in a private hospital. Other risk factors that were stronger in public hospitals included the following: advanced maternal age, high maternal education, nulliparity, high number of prenatal visits, multiple pregnancy, hospital with low annual volume of deliveries, birth outside the city of residence and white skin color. Discussion: These results may be explained by the obstetric care model of private hospitals, which is not multiprofessional. Prenatal care and delivery are conducted by the same doctor and rarely include the input of another professional, such as a midwife. In addition, the mode of delivery influences the professional’s payment.
