The influence of perception of care and maternal protection on breastfeeding practices on the infants' third month of life / Influência da percepção do cuidado e da proteção materna sobre as práticas de aleitamento materno em lactentes no terceiro mês de vida

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.

Diagnóstico Psicodinâmico Operacionalizado (OPD-2) em pacientes com comportamento suicida prévio / Operationalized Psychodynamic Diagnosis (OPD-2) in patients with previous suicidal behavior

OBJETIVO: avaliar o funcionamento psicodinâmico de pacientes pós-tentativa de suicídio através do Diagnóstico Psicodinâmico Operacionalizado (OPD-2) e de outros instrumentos complementares. MÉTODOS: estudo de caso utilizando métodos mistos de análise (quali-quantitativa). Os pacientes foram avaliados em follow up 3 anos após a primeira entrevista (que ocorreu logo após a tentativa de suicídio), e dois deles concordaram em participar do follow up. RESULTADOS: observou-se nível moderado de funcionamento global nos pacientes. Os conflitos psíquicos com maior prevalência foram o de 'autoestima' e 'necessidade de ser cuidado' versus 'autossuficiência'. Em suas relações, mostraram-se dependentes, impulsivos e exigentes, o que ocasiona sensação constante de abandono. Nessa perspectiva, o medo de ser abandonado faz com que se distanciem e se isolem. Os fatores protetivos de tendências suicidas foram a qualidade da rede de apoio (MOS), a maior interação social, a maior estabilidade do self, o nível de defesas maduras e o tratamento em saúde mental posterior à alta hospitalar. CONCLUSÃO: o OPD-2 demonstrou-se um instrumento apropriado para uma ampla compreensão psicológica de pessoas que tiveram tentativas de suicídio.(AU)

OBJECTIVE: to evaluate the psychodynamic functioning of patients after suicide attempts through the Operationalization Psychodynamic Diagnosis (OPD-2) and other complementary instruments. METHODS: case study using mixed methods of analysis (quali-quantitative). Patients were evaluated in follow up 3 years after the first interview (which occurred shortly after the suicide attempt), and two of them has agreed in participating of the follow up. RESULTS: a moderate level of overall functioning was observed in the patients. The most prevalent psychic conflicts were 'self-esteem' and 'need to be cared for' versus 'self-sufficiency'. In their relationships, they have shown up to be dependent, impulsive and demanding, which causes a constant feeling of abandonment. In this perspective, the fear of being abandoned causes them to distance themselves and be isolated. The protective factors of suicidal tendencies were the quality of the support network (MOS), the greater social interaction, the greater stability of the self, the level of mature defenses and the mental health treatment after hospital discharge. CONCLUSION: OPD-2 proved to be an appropriate instrument for a broad psychological comprehension of people who had suicide attempts.(AU)

OBJETIVO: evaluar el funcionamiento psicodinámico de pacientes tras intentos de suicidio a través del Diagnóstico Psicodinámico Operacionalizado (OPD-2) y otros instrumentos complementarios. MÉTODOS: estudio de caso utilizando métodos mixtos de análisis (cuali-cuantitativo). Los pacientes fueron evaluados en el seguimiento 3 años después de la primera entrevista (que ocurrió poco después del intento de suicidio), y dos de ellos han aceptado participar del seguimiento. RESULTADOS: se observó un nivel moderado de funcionamiento general en los pacientes. Los conflictos psíquicos más prevalentes fueron la "autoestima" y la "necesidad de ser atendido" versus la "autosuficiencia". En sus relaciones se han mostrado dependientes, impulsivos y exigentes, lo que provoca un constante sentimiento de abandono. En esta perspectiva, el miedo al abandono hace que se distancien y se aíslen. Los factores protectores de las tendencias suicidas fueron la calidad de la red de apoyo (MOS), la mayor interacción social, la mayor estabilidad del yo, el nivel de defensas maduras y el tratamiento de salud mental tras el alta hospitalaria. CONCLUSIÓN: OPD-2 resultó ser un instrumento apropiado para una amplia comprensión psicológica de las personas que tuvieron intentos de suicidio.(AU)

Infant processed food consumption and their interaction to breastfeeding and growth in children up to six months old.

BACKGROUND: Evidences suggest that early processed food (PF) consumption may cause harm to infant health. During the first 6 months of life, it is not known whether the timing and quantity of this food group can impact breastfeeding and growth. The aim of the study was to analyze the associations between time of introduction and quantity of infant PF consumption with duration of breastfeeding and infant growth at 6 months of age. METHODS: Data were longitudinally collected in six interviews, from birth to 6 months, in a sample of Brazilian newborns with adverse intrauterine environments. PF consumption was calculated by gravity score of processed foods (GSPF) in relation to feeding supply quality and time. For the analysis, the scores were divided into tertiles, making scores severities: Null, Mild, Moderate, and Severe. The interaction between GSPF and breastfeeding (exclusive and non-exclusive) and growth parameters (analyzed in Z-scores, by weight for height, weight for age, and body mass index for age) was tested. RESULTS: A total of 236 infants were included in the study. Greater GSPF were associated with better rates of breastfeeding practices and higher growth indicators scores in the sixth month of infants. These findings were confirmed after adjustment for family income, maternal age, pre-gestational body mass index, and growth z scores at birth. CONCLUSION: The harms of eating PF in relation to breastfeeding and infant growth are more evident the greater and earlier they are consumed. Future studies should explore interventions to reduce and delay the consumption of these foods to prevent adverse health outcomes in later life.

Association of physical activity levels and the prevalence of COVID-19-associated hospitalization.

OBJECTIVES: We compared physical activity levels before the outbreak and quarantine measures with COVID-19-associated hospitalization prevalence in surviving patients infected with SARS-CoV-2. Additionally, we investigated the association of physical activity levels with symptoms of the disease, length of hospital stay, and mechanical ventilation. DESIGN: Observational, cross-sectional. METHODS: Between June 2020 and August 2020, we invited Brazilian survivors and fully recovered patients infected with SARS-CoV-2 to respond to an online questionnaire. We shared the electronic link to the questionnaire on the internet. We collected data about clinical outcomes (symptoms, medications, hospitalization, and length of hospital stay) and cofactors, such as age, sex, ethnicity, preexisting diseases, socioeconomic and educational, and physical activity levels using the International Physical Activity Questionnaire (IPAQ short version). RESULTS: Out of 938 patients, 91 (9.7%) were hospitalized due to COVID-19. In a univariate analysis, sex, age, and BMI were all associated with hospitalizations due to COVID-19. Men had a higher prevalence of hospitalization (66.6%, p = 0.013). Patients older than 65 years, obese, and with preexisting disease had a higher prevalence of COVID-19-related hospitalizations. In a multivariate regression model, performance of at least 150 min/wk (moderate) and/or 75 min/wk (vigorous) physical activity was associated with a lower prevalence of hospitalizations after adjustment for age, sex, BMI, and preexisting diseases (PR = 0.657; p = 0.046). CONCLUSIONS: Sufficient physical activity levels were associated with a lower prevalence of COVID-19-related hospitalizations. Performing at least 150 min a week of moderate-intensity, or 75 min a week of vigorous-intensity physical activity was associated with 34.3% reduction in prevalence.

Association between anger expression and attempted suicide at a general emergency hospital in the south of Brazil.

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.

Anxiety Sensitivity and Panic Disorder: Evaluation of the Impact of Cognitive-Behavioral Group Therapy.

Anxiety sensitivity (AS) is a multidimensional construct associated with the etiology and maintenance of panic disorder (PD) symptoms. However, only a few studies have evaluated whether cognitive-behavioral group therapy (CBGT) can modify the condition. The objective of this study was to evaluate the impact of CBGT on AS in patients with PD and to analyze AS and its dimensions as predictors of response to CBGT. In the present clinical trial, an intervention group (n = 37) attended 12 CBGT sessions, while a control group (n = 52) did not receive any intervention. The severity of symptoms and of AS were evaluated before and after CBGT in the intervention group and once in the control group. Significant improvement occurred in all specific PD symptoms and in general anxiety and depressive symptoms. Furthermore, AS scores reduced significantly after intervention. This study confirmed that AS is higher in patients with more severe PD. The effectiveness of CBGT for reducing the physical, cognitive, and social dimensions of AS was also observed, supporting the hypothesis of a positive impact of therapy.

Translation and cultural adaptation of the DSM-5 Personality Inventory - Brief Form (PID-5-BF)

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.

Brief antibullying intervention for adolescents in public schools.

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.

The association between traumatic experiences and suicide attempt in patients treated at the Hospital de Pronto Socorro in Porto Alegre, Brazil.

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.

Associação entre precocidade do trauma psíquico e tentativas de suicídio: uma experiência de pesquisa / Association between precocity of psychic trauma and suicide attempts: a research experience

Experiências traumáticas na infância podem gerar sofrimento psicológico e aumento das vulnerabilidades e predisposições para posterior desenvolvimento de psicopatologias na vida adulta. Sintomas de comportamentos autodestrutivos e tentativas de suicídio estão entre algumas das fortes possibilidades de manifestações. O presente estudo foi realizado em um hospital de emergência, em Porto Alegre/RS, e teve como objetivo principal estudar a correlação entre traumas na infância perpetrados por figuras parentais e a TS na adultez, em uma amostra de pessoas que internaram como sobreviventes de TS. Os resultados apontaram associação entre eventos traumáticos na infância e posterior tentativa de suicídio na vida adulta. Essa correlação realça o papel do trauma psíquico precoce no desejo de interromper a própria vida posteriormente. Fica visível a necessidade de compreensão das consequências dos traumas infantis, bem como a necessidade de serem pensadas intervenções precoces na infância e nos adultos vítimas de trauma. Novos estudos são sugeridos.(AU)

Traumatic childhood experiences can generate psychological distress and the increase vulnerabilities and predispositions for later development of psychopathologies in adulthood. Symptoms of self-defeating behaviors as well as suicide attempts are among some of the strong possibilities for manifestations. The present study was conducted in an emergency hospital in Porto Alegre/RS and its main objective was to study the correlation between childhood trauma perpetrated by parental figures and TS in adulthood, in a sample of people who were hospitalized as TS survivors. The results of the investigation pointed to the association between the presence of trauma in childhood and suicide attempts in adulthood. The results showed an association between traumatic events in childhood and subsequent suicide attempt in adulthood. This correlation highlights the role of early psychic trauma in the desire to interrupt their own lives later. The need to understand the consequences of childhood trauma and the need to think about early interventions in childhood and in trauma victims adults is visible. New studies are suggested.

Evaluation of BDNF levels in patients hospitalized for physical trauma at an emergency hospital in Porto Alegre, southern Brazil / Avaliação dos níveis de BDNF em pacientes hospitalizados por trauma físico em um hospital de emergência de Porto Alegre, sul do Brasil

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 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.

Maternal Weight Variation in Different Intrauterine Environments: An Important Role of Hypertension.

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 6 months 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.

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 (pré-gravidez, 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 com sobrepeso 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.

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.

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.

Markers for Severity of Problems in Interpersonal Relationships of Crack Cocaine Users from a Brazilian Multicenter Study.

Crack cocaine users frequently report difficulties regarding having healthy and rewarding relationships. Factors other than the use of crack cocaine itself may be at play when it comes to being able to develop healthier connections with partners, adult relatives and close friends. To verify which factors, including demographics, substance abuse related factors and psychiatric comorbidities could be markers for a higher severity of problems in interpersonal relationships of crack cocaine users seeking for treatment. This was a cross-sectional study, conducted between April 2011 and November 2012. Participants were 407 crack cocaine users seeking treatment in specialized public facilities of six Brazilian capitals. The relationship of severity of problems in the family/social area and the prevalence of psychiatric disorders, exposure to stressful events, substance use related factors and practice of illicit activities were explored through multivariate analyses. Number of days using crack cocaine in the last 30 days, age of first time using alcohol and feeling its effects, a diagnosis of alcohol abuse, posttraumatic stress disorder, antisocial personality disorder and attention-deficit/hyperactivity disorder were significantly associated with a higher severity of problems in interpersonal relationships with partners, adult relatives and friends. Problems in interpersonal relationships are strongly related to specific psychiatric comorbidities and the frequency of crack cocaine use. Factors identified by this study can make the paths to recovery more challenging. These results support psychosocial interventions that focus in the improvement of interpersonal relationships of crack cocaine users.

Yoga and breathing technique training in patients with heart failure and preserved ejection fraction: study protocol for a randomized clinical trial.

BACKGROUND: Current therapies for heart failure (HF) are followed by strategies to improve quality of life and exercise tolerance, besides reducing morbidity and mortality. Some HF patients present changes in the musculoskeletal system and inspiratory muscle weakness, which may be restored by inspiratory muscle training, thus increasing respiratory muscle strength and endurance, maximal oxygen uptake (VO2), functional capacity, respiratory responses to exercise, and quality of life. Yoga therapies have been shown to improve quality of life, inflammatory markers, and peak VO2 mostly in HF patients with a reduced ejection fraction. However, the effect of different yoga breathing techniques in patients showing HF with a preserved ejection fraction (HFpEF) remain to be assessed. METHODS/DESIGN: A PROBE (prospective randomized open blinded end-point) parallel-group trial will be conducted at two specialized HF clinics. Adult patients previously diagnosed with HFpEF will be included. After signing informed consent and performing a pre-test intervention, patients will be randomized into three groups and provided with either (1) active yoga breathing techniques; (2) passive yoga breathing techniques (pranayama); or and (3) control (standard pharmacological treatment). Follow-up will last 8 weeks (16 sessions). The post-intervention tests will be performed at the end of the intervention period for analysis of outcomes. Interventions will occur continuously according to patients' enrollment. The main outcome is respiratory muscular resistance. A total of 33 enrolled patients are expected. The present protocol followed the SPIRIT guidelines and fulfilled the SPIRIT checklist. DISCUSSION: This trial is probably the first to assess the effects of a non-pharmacological intervention, namely yoga and specific breathing techniques, to improve cardiorespiratory function, autonomic system, and quality of life in patients with HFpEF. TRIAL REGISTRATION: REBEC Identifier: RBR-64mbnx (August 19, 2012). Clinical Trials Register: NCT03028168 . Registered on 16 January 2017).

Leptin levels and its correlation with crack-cocaine use severity: A preliminary study.

BACKGROUND: Crack-cocaine is an important public health problem in Brazil and worldwide. It is a potent form of cocaine which results in rapid and damaging stimulating effects on the central nervous system through inhibition of the dopamine transporter. Some studies have suggested that both food and drugs - including crack, can act on the same brain reward mechanisms, altering the dopamine pathways that modulate behavioral responses. Our hypothesis was that leptin, a well-known peptide that modulates energy metabolism and appetite, can be used as a biomarker for drug use. METHODS: Anthropometric data, drug use profiles, and leptin serum levels were evaluated in a cross-sectional study of 40 crack-cocaine users. RESULTS: Leptin showed an inverse correlation with the severity of crack use, and this correlation remained when corrected by body mass index (BMI) and body composition by bioimpedance (BIA). The majority of subjects were eutrophic or overweight/obese considering BMI and BIA, and these variables were not significantly associated with the severity of crack use, but positively correlated with leptin levels. CONCLUSIONS: Our preliminary findings suggest that leptin could be involved in drug use severity, perhaps through pathways similar to those whereby it modulates food intake. Considering the anthropometric parameters, these findings provide additional evidence that low weight is not predominant in crack users.
