Abstract Objectives: to evaluate the influence of perception of care and maternal protection on breastfeeding practices on the infants’ third month of life. Methods: longitudinal study with mother-infant pairs distributed in five groupsof gestational clinical conditions. The recruitment occurred in the period 2011 to 2016 at three hospitals in the public health systems in Porto Alegre, Brazil. The Parental Bonding Instrument and the Edinburgh Postpartum Depression Scale were assessed. Exclusive and prolonged breastfeeding were analyzed by questionnaires. Data were analyzed by one-way ANOVA with Tukey’s post-hoc test, Kruskal-Wallis with Dunn’s post-hoc test, or Pearson’s chi-squared test. The significance was set at 5%. Results: 209 mother-infant pairs were investigated. Among those who did not practice breastfeeding, a lower perception of care, a higher perception of maternal protection, and a higher score of postpartum depression were observed (p=0.022, p=0.038, and p<0.001, respectively), when compared to peers who practiced. The control group had a significantly higher perception of care when compared to thediabetes mellitus group (p=0.006), and the perception of maternal protection and postpartum depression had no differences between the intrauterine groups (p>0.05). Conclusions: the perception of care and maternalprotection and the postpartum depressive symptomatology influenced breastfeeding at three months. It is possible to assume a transgenerational effect on breastfeeding, suggesting the existence of a complex model related to mental health in a sample of women who had different backgrounds of gestational clinical conditions

Resumo Objetivos: avaliar a influência da percepção do cuidado e da proteção materna sobre as práticas de aleitamento materno em lactentes no terceiro mês de vida. Métodos: estudo longitudinal, com pares mães-lactentes distribuídos em cinco grupos de diferentes condições clínicas gestacionais. O recrutamento ocorreu no período de 2011 a 2016 em três hospitais da rede pública de saúde de Porto Alegre, Brasil. Foram utilizados o Parental Bonding Instrument e o Edinburgh Postpartun Depression Scale. O aleitamento materno exclusivo e continuado foi analisado por questionários. Na análise de dados foram utilizados os testes de ANOVA com post-hoc de Tukey, Kruskal-Wallis com post-hoc de Dunn e Qui-quadrado. Resultados: foram investigados 209 pares mães-lactentes. Entre aqueles que não praticaram o aleitamento materno foi observadouma menor percepção de cuidado materno, uma maior percepção de proteção materna e ummaior escore de depressão pós-parto (p=0,022, p=0,038 e p<0,001, respectivamente) quandocomparados aos pares mães-lactentes que praticaram. O grupo controle teve significativamente maior percepção do cuidado materno quando comparado ao grupo com diabetes mellitus (p=0,006) enquanto a percepção de proteção materna e a depressão pós-parto não apresentaram diferenças entre os cinco grupos intrauterinos (p>0,05). Conclusões: a percepção de cuidado e proteção materna e asintomatologia depressiva pós-parto influenciaram o aleitamento materno aos três meses. É possível assumir um efeito transgeracional no aleitamento materno, sugerindo a existência de um modelo complexo relacionado à saúde mental numa amostra de mulheres que tinham diferentes antecedentes de condições clínicas gestacionais.

Abstract Microplastics are ubiquitous contaminants of marine ecosystems around the world and Antarctica is no exception. Microplastics can be influenced by sedimentary dynamics mainly on coastal areas where they are more abundant in Antarctica. This study evaluated microplastic contamination in beach environments from two Antarctic Specially Protected Areas, aiming to identify relationships between microplastic numbers and sedimentological parameters on beach sediments. Low numbers of microplastics were found (> 0.5 mm; fibers excluded) – one particle per sample in 4 of 15 samples analyzed – and there is no evidence of widespread contamination. Sedimentological parameters reveal differences between sampled environments, but low numbers of microplastics impaired statistical comparison. All sediment samples are coarse, denoting highenergy depositional environments that are likely little susceptible to microplastic accumulation. Microplastic contamination in the Antarctic coastal ecosystem is heterogeneous, and their detailed characterization assisted by a systematization of methods can improve the understanding of microplastics distribution patterns in the cold coastal ecosystem.

Abstract Introduction Suicide is one of the leading causes of death in the world. For every person who commits suicide, twenty or more have attempted to take their own lives. The emotional state of anger is often associated with suicidal behavior. However, this association needs to be further clarified. Objectives This study sought to investigate the profiles of traits and expressions of anger in inpatients admitted to a general emergency hospital after surviving a suicide attempt. Methods In this case-control study, a sample of 28 suicide survivors was matched for sex, age, and educational level with 56 controls. The State-Trait Anger Expression Inventory-2 was used to measure anger traits and expression. Results Suicide survivors scored higher for anger traits and expression and lower for anger control than the control group. They also had lower levels of state anger and willingness to express anger verbally than the control group. Conclusions Patients who attempted suicide and had high scores for anger expression (in and out) are inclined to have extreme difficulty in interpersonal relationships and rigidity towards change and are at higher risk of developing psychopathologies.

Abstract Introduction The Personality Inventory for the DSM-5 – Brief Form (PID-5-BF) – is an instrument for assessment of the five pathological personality traits from the Diagnostic and Statistical Manual of Mental Disorders, 5th edition (DSM-5) alternative model of personality disorders. Objectives To determine the psychometric properties of the version of the PID-5-BF translated and adapted to Brazilian Portuguese. Methods The process of translating and cross-culturally adapting the text was carried out by independent translators and the resulting version was administered to 176 patients in two hospitals in Rio Grande do Sul. The internal structure was tested by means of confirmatory factor analysis. Evidence of reliability was tested by examining the internal consistency of the scales and their convergent and concurrent validity with other methods of psychopathology. Results The five factors were replicated in the present sample with adequate indicators of fit of the data to the model. Appropriate reliability coefficients for the scales and evidence of validity were observed, indicating the clinical usefulness of the PID-5-BF in the Brazilian context. Conclusion The psychometric properties of PID-5-BF proved satisfactory in an initial sample of Brazilians.

Abstract Background: Only few studies have analyzed the pharmaceutical workforce in primary healthcare centers, and a global recommendation calls for better understanding of the trends that shape workforce development and capacity. Objective: To analyze the distribution of the pharmaceutical workforce in primary healthcare centers in the national health system [Sistema Único de Saúde (SUS)] in Brazil. Methods: The study was conducted using data from the National Survey on Access, Use and Promotion of Rational Use of Medicines in Brazil. Secondary data referring to the socioeconomic indicators of each municipality were obtained from national public databases. Data stratification in geographic regions was considered, and data on workers in the management of the municipal pharmaceutical services and medicines dispensing centers were analyzed. Crude and adjusted prevalence ratios were calculated by Poisson regression in the study investigating the factors associated with low and high-density pharmacists per 10,000 inhabitants. Results: The results showed that most Brazilian municipalities have a rate of 1 or more pharmacist per 10,000 inhabitants in primary healthcare public facilities, with a higher concentration of pharmacists in small municipalities. Even in Brazilian municipalities with lower economic capacity, the conditions of access to medicines and pertinent information on medicines were directly related to the number of pharmacists available in these centers. Conclusions: This study showed a high number of pharmacists in the public health system. The higher density of pharmacists in primary healthcare public facilities correlated to increased access to medicines information and better municipal social development.

Abstract Objective To analyze associations between attempted suicide and childhood trauma. Methods A seven month comparative case-control study (28 subjects – patients with suicide attempt; 56 controls – patients without suicide attempt). The following instruments were used: Childhood Trauma Questionnaire (CTQ), Mini International Neuropsychiatric Interview (MINI), and Medical Outcomes Study (MOS). Results The group with suicide attempt had significantly higher scores for some variables: emotional abuse (p < 0.001), physical abuse (p < 0.001), emotional neglect (p < 0.001), and physical neglect (p < 0.001). Conclusions The results suggest that variables related to previous trauma may influence future suicide attempts. The adoption of preventive and therapeutic actions related to mistreatments during child development is a crucial factor in reduction of suicide risk.

ABSTRACT Objectives: To assess the results of a brief antibullying intervention for adolescents in public schools. Method: This was a controlled experimental study whose subjects were 1,043 students in 5th through 9th grades from public schools in Porto Alegre/State of Rio Grande do Sul, conducted between April and November 2015. Adolescents and school teachers randomly assigned to the intervention group participated in two meetings focused on educative aspects of bullying. Outcome was assessed using the Bullying Questionnaire - victim and perpetrator version. Generalized Estimating Equations was used to evaluate the effect of the intervention. Results: Average age of subjects was 12.5 (SD=1.62) years. A total of 613 (58.7%) adolescents participated in interventions. They were compared to 430 (41.3%) participants in the control group. The study did not observe any significant difference in bullying scores after the intervention. Conclusions: This study indicates the usefulness of clarifying precisely what bullying is in schools as part of an initial approach to an educative strategy on this topic.

Resumo Objetivo Verificar a associação entre os níveis de fator neurotrófico derivado do cérebro (brain-derived neurotrophic factor [BDNF]) e transtorno de estresse agudo (TEA) em pacientes que sofreram trauma físico. Métodos Os dados foram coletados em um hospital de emergência de Porto Alegre, Rio Grande do Sul, Brasil. Os participantes eram maiores de 18 anos, vítimas de trauma físico e estavam hospitalizados por um período mínimo de 48 horas. Um total de 117 pacientes hospitalizados que concordaram em participar da pesquisa foram agrupados de acordo com o turno de realização da coleta de sangue (38 sujeitos no turno da manhã e 79 sujeitos no turno da tarde), tiveram seus níveis de BDNF medidos e responderam a outros questionários. Os entrevistados também foram agrupados por idade em três faixas etárias: 18-30, 31-50 e 51-70 anos. Resultados Encontramos uma diferença significativa na distribuição de BDNF entre os turnos, sendo que o grupo da tarde apresentou níveis maiores de BDNF (U = 1906,5, p = 0,018). Houve diferença entre o grupo de 18-30 anos e o de 51-70 anos no turno da tarde (Umanhã = 1107, pmanhã = 0,575; Utarde = 7175, ptarde = 0,028). Conclusões A população cuja coleta ocorreu à tarde apresentou valores significativamente maiores de BDNF em relação à coleta do turno da manhã. Esta mesma população apresentou menores níveis dessa neurotrofina quando associada com os subtipos A1, A2 e A de TEA. É possível hipotetizar que os menores valores de BDNF aferidos na coleta do turno da manhã se devam a uma resposta ao ciclo circadiano do cortisol, cuja ação inibe a expressão de neurotrofinas séricas.

Abstract Objective To assess the association between brain-derived neurotrophic factor (BDNF) levels and acute stress disorder (ASD) in patients who have suffered physical trauma. Methods Data were collected at an emergency hospital in Porto Alegre, state of Rio Grande do Sul, southern Brazil. Participants were over 18 years of age, victims of physical trauma, and had been hospitalized for a minimum of 48 hours. A total of 117 hospitalized patients who agreed to participate in the research were grouped according to the shift in which blood was collected (38 subjects from the morning shift and 79 from the afternoon shift), had their BDNF levels measured and responded to other questionnaires. Respondents were further grouped by age into three ranges: 18-30, 31-50 and 51-70 years. Results We found a significant difference in the distribution of BDNF between the two shifts in which blood samples were collected, with the afternoon group having higher BDNF levels (U = 1906.5, p = 0.018). A difference was observed only between the 18-30 group and the 51-70 group in the afternoon shift (Umorning = 1107, pmorning = 0.575; Uafternoon = 7175, pafternoon = 0.028). Conclusions The population whose blood samples were collected in the afternoon showed significantly higher values of BDNF compared to those of the morning shift. This same population presented lower BDNF levels when associated with ASD subtypes A1, A2, and A. We hypothesize that the lower values of BDNF measured in the morning shift were due to a response to the circadian cycle of cortisol, whose action inhibits the expression of serum neurotrophins.

Resumo Objetivo Diferentes ambientes intrauterinos podem influenciar a variação de peso corporal pré-gestacional materno até 6 meses pós-parto. O objetivo do presente estudo foi verificar a associação de fatores sociodemográficos, obstétricos, nutricionais e comportamentais com a variação de peso em mulheres divididas em quatro grupos: hipertensas (HM), diabéticas (DM), tabagistas (SM) e controles (CM). Métodos Amostra de conveniência de 124 puérperas recrutadas em 3 hospitais públicos da cidade de Porto Alegre, Rio Grande do Sul, Brasil, entre 2011 e 2016. Regressões lineares múltiplas e modelos de equações de estimativas generalizadas (GEE) foram realizados para identificar os fatores associados à variação do peso materno. Para todas as GEE, as medidas de peso materno foram ajustadas para a estatura materna, paridade, escolaridade e tipo de parto, e três medidas de peso (prégravidez, anterior ao parto e 15 dias pós-parto) foram fixadas. Resultados Um modelo hierárquico associou o diagnóstico materno de hipertensão e o índice de massa corporal (IMC) pré-gestacional de sobrepeso com ganho de peso materno medido até o 6° mês pós-parto (diferença entre o peso materno aos 6 meses pós-parto e o peso pré-gestacional). Estes resultados mostraram que o grupo HM e mulheres comsobrepeso aumentaram o peso corporal em ~ 5,2 kg 6 meses pós-parto, em comparação com os demais grupos. Além disso, as mulheres classificadas com sobrepeso tiveram uma variação maior de peso corporal, de 3,150 kg. Conclusão Evidenciou-se a necessidade de diretrizes nutricionais específicas para distúrbios hipertensivos gestacionais, bem como de maior atenção dos serviços de saúde públicos para mulheres com excesso de peso em idade fértil.

Abstract Objective Different intrauterine environments may influence the maternal prepregnancy body weight (BW) variation up to 6 months postpartum. The objective of the present study was to verify the association of sociodemographic, obstetric, nutritional, and behavioral factors with weight variation in women divided into four groups: hypertensive (HM), diabetic (DM), smokers (SM), and control mothers (CM). Methods It was a convenience sample of 124 postpartum women recruited from 3 public hospitals in the city of Porto Alegre, state of Rio Grande do Sul, Brazil, between 2011 and 2016.Multiple linear regressions and generalized estimating equations (GEE) were conducted to identify the factors associated with maternal weight variation. For all GEE, the maternal weight measurements were adjusted for maternal height, parity, educational level, and the type of delivery, and 3 weight measurements (prepregnancy, preceding delivery, and 15 days postpartum) were fixed. Results A hierarchical model closely associated the maternal diagnosis of hypertension and a prepregnancy body mass index (BMI) classified as overweight with maternal weight gain measured up to the 6th month postpartum (the difference between the maternal weight at 6months postpartum and the prepregnancy weight). These results showed that the BW of the HM group and of overweight women increased ~ 5.2 kg 6 months postpartum, compared with the other groups. Additionally, women classified as overweight had a greater BW variation of 3.150 kg. Conclusion This evidence supports the need for specific nutritional guidelines for gestational hypertensive disorders, as well as great public attention for overweight women in the fertile age.

ABSTRACT Ferrimagnetic Fe-oxides are important soil components, which are present in most of the agricultural soils of Brazil. Distinction, origin, and assessment of the influence of these minerals on magnetism and geochemistry is a challenge for mineralogists. This study aimed to characterize mineralogically Fe-rich Rhodic Oxisols ( Latossolos Vermelhos ) originating from several mafic rocks in Brazil, and assess the implications on their magnetic and geochemical properties. We present results on magnetic measurements, chemical dissolutions, X-ray diffractometry, Rietveld refinement, Raman, and Mössbauer spectroscopies of Fe-rich Rhodic Oxisols originating from several mafic rocks. They show that magnetite is inherited from the parent material, and its oxidation leads to the formation of maghemite. In the coarse fractions (sand and silt), magnetite and maghemite coexist and are interstratified with hematite, confirmed by Raman spectroscopy. This limited the distinction between magnetite and maghemite by Mössbauer spectroscopy. Maghemite represents the only ferrimagnetic Fe oxide in the clay fraction. The influence of both ferrimagnetic minerals, magnetite and maghemite, on magnetic susceptibility and total content of trace elements is determined by the pedogenic development, even among highly weathered soils. In general, the coarse fractions contribute with most of the total trace element contents, while the clay fraction contributes to trace elements availability and magnetic susceptibility of soils.

Objective: To evaluate the nutritional status of crack users and to analyze its correlation with drug use profiles. Methods: Cross-sectional study with 108 crack users. Anthropometric data were assessed through body mass index (BMI) and bioimpedance (BIA) measurements. A blood test to analyze hematocrit, hemoglobin, glucose, and lipid profiles was also performed. Crack use was determined through a standardized interview. Results: Based on BMI and BIA, most individuals were eutrophic (about 70%). Regarding hematological parameters, we found that hemoglobin and hematocrit levels were below normal for 32.4 and 30.6% of patients, respectively. Considering normal parameters, a large part of the sample (60.2%) had low levels of HDL cholesterol and high levels of triglycerides (38%). There were no significant correlations between drug profile and nutritional variables. Conclusion: This is a pioneering study that examines the nutritional status of crack users. Our results showed that most crack users present normal anthropometric findings and the prevalence of underweight is low. However, blood analysis showed changes and a specific type of malnutrition.

Abstract This study compared the effects of two metacognitive interventions on writing, working memory (WM), and behavioral symptoms of students with attention-deficit/hyperactivity disorder (ADHD). The disorder was clinically diagnosed by a multidisciplinary team according to DSM-IV criteria. The first approach consisted of a combined intervention in text production and WM while the second focused only on WM. Participants were 47 students from the fifth to ninth grades of two public elementary schools in Porto Alegre (Brazil), randomized to one of the two interventions groups. Writing and WM were assessed before, immediately after, and 3 months after the interventions. The results suggest that both interventions contributed to improving behavior and school performance, whereas only the combined intervention increased the overall quality of narrative text, organization of paragraphs, and denouement.

The objective of this work was to synthesize and characterize Layered Double Hydroxides (MgAl-LDHs, MgFe-LDHs, and MgAlFe-LDHs) containing phosphate anions and study P release kinetics was conducted with the prepared materials. The release kinetics tests were performed in water by the stirred-flow method to verify the P release profile from LDHs materials. Results showed LDHs have similar characteristics to those of reactive sources of P, such as thermophosphates. The LDHs presented gradual P release and the LDH prepared with the molar ratio of cations Mg:Al = 2:1 showed a more sustained profile of P release compared to other produced materials. Thus, the chemical and structural characteristics of the LDHs make them potential materials for the use and storage of slow P release fertilizer.

Objective: Many studies correlate characteristics of family functioning and the development of drug addiction. This study sought to evaluate and compare the family environment styles of two groups of psychoactive substance users: 1) alcohol-only users and 2) crack-cocaine users. Methods: Three hundred and sixty-four users of alcohol, crack-cocaine, and other drugs, recruited from research centers in four Brazilian capitals participated in this study. Subjects were evaluated through the Family Environment Scale and the Addiction Severity Index, 6th version (ASI-6). ASI-6 t-scores were compared by analysis of variance (ANOVA) and post-hoc tests. A final model was obtained using a logistic regression analysis. All analyses were adjusted for partner, age, and psychiatric t-score. Results: We found a significant difference between groups in the cohesion subscale (p = 0.044). The post-hoc test revealed a difference of 1.06 points (95%CI 0.11-2.01) between groups 1 (6.45±0.28) and 2 (5.38±0.20). No significant between-group differences were observed in the other subscales. However, categorical analyses of variables regarding family dynamic showed that crack users more often reported that sometimes people in their family hit each other (30.4% vs. 13.2%, p = 0.007) and that people in their family frequently compared each other regarding work and/or school achievement (57.2% vs. 42.6%, p = 0.041). Conclusion: These results suggest that families of crack-cocaine users are less cohesive than families of alcohol users. This type of family environment may affect treatment outcome, and should thus be adequately approached.
