The golden hour for postpartum hemorrhage: Results from a prospective cohort study.

OBJECTIVE: To evaluate the predictive capacity of vital signs for the diagnosis of postpartum hemorrhage (PPH). METHODS: A prospective cohort study performed at the University of Campinas, Brazil, between February 2015 and March 2016 with women who delivered vaginally. Vital signs and postpartum bleeding were collected over 24 h. Exploratory data analysis was performed plus receiver operating characteristic curve analysis where the areas under the curve was used to determine the best cutoff points for sensitivity, specificity, likelihood ratio, and diagnostic odds ratio. RESULTS: For the 270 women recruited, mean blood loss after 120 min was 427.49 ± 335.57 ml, while 84 (31.1%) and 22 (8.1%) women had blood loss ≥500 and ≥1000 ml, respectively. Heart rate cutoff point of 105 bpm measured between 21-40 min after birth identified blood loss ≥1000 ml with 90% specificity. A shock index (SI) of 0.965 at 41-60 min after birth identified blood loss ≥500 and ≥1000 ml within 2 h with approximately 95% specificity. CONCLUSION: Shock index and heart rate measured after birth showed high specificity with low sensitivity to identify PPH. In clinical practice, "The rule of 1s" should receive special attention: SI ≥1, or heart rate >100 bpm, or estimated blood loss ≥1 L.

Understanding How Health Providers Identify Women with Postpartum Hemorrhage: A Qualitative Study / Compreendendo como os profissionais de saúde identificam as mulheres com hemorragia pós-parto: um estudo qualitativo

Abstract Objective To identify how health providers recognize postpartum hemorrhage early and the difficulties involved in it. Methods An exploratory, descriptive study using a qualitative approach through a semi-structured interview technique. In total, 27 health professionals (nursing tech nicians, nurses, medical residents in Gynecology and Obstetrics, hired medical doctors, and medicine professors) working in a tertiary-level hospital of reference in women's health care in the State of São Paulo, Brazil, participated in the study through an invitation. After they accepted the invitation, they signed the free and informed consent form. All interviews were recorded and transcribed, and a thematic analysis was conducted. We found three analysis categories: a) perception of the severity: "there is something wrong with the women"; b) difficulties in the early diagnosis of postpartum hemorrhage; and c) the process to improve obstetrical care. Results Caregivers believe teamwork and communication should be improved. Besides the visual estimation of blood loss, the nursing team is attentive to behavioral symptoms like irritability, while the medical staff follow protocols and look for objective signs, such as altered vital signs. Conclusion Besides the objective evaluations, the subjective perceptions of the providers are involved in the clinical judgement regarding the diagnosis of postpartum hemorrhage, and this should be included in a broader diagnosis strategy.

Resumo Objetivo Identificar como os profissionais de saúde reconhecem precocemente os casos de hemorragia pós-parto e as suas dificuldades. Métodos Realizou-se um estudo exploratório, descritivo, com uma abordagem qualitativa por meio da técnica de entrevista semiestruturada. Por meio de um convite, participaram do estudo 27 profissionais saúde (técnicas de enfermagem, enfermeiras, residentes de Ginecologia e Obstetrícia, e médicos contratados e docentes) que trabalhavam em um hospital de nível terciário de referência no atendimento à saúde da mulher no estado de São Paulo. Depois que os participantes aceitaram o convite, eles assinaram o termo de consentimento livre e esclarecido. Todas as entrevistas foram gravadas, transcritas, e realizou-se uma análise temática. Identificaram-se três categorias de análise: a) percepção da gravidade: "há algo de errado com as mulheres"; b) dificuldades no diagnóstico precoce da hemorragia pós-parto; e c) o processo para melhorar a atenção em obstetrícia. Resultados Os profissionais de saúde acreditavam que o trabalho em equipe e a comunicação deviam ser aperfeiçoados. Além da estimativa visual da perda de sangue, a equipe de enfermagem estava atenta a sintomas comportamentais como irritabilidade, ao passo que o pessoal médico seguia protocolos e procurava sinais objetivos, como sinais vitais alterados. Conclusão Além das avaliações objetivas, as percepções subjetivas dos provedores estão envolvidas no julgamento clínico do diagnóstico de hemorragia pós-parto, e isto deve ser incluído em uma estratégia de diagnóstico mais ampla.

Multidimensional assessment of women after severe maternal morbidity: the COMMAG cohort study.

OBJECTIVES: To perform a multidimensional assessment of women who experienced severe maternal morbidity (SMM) and its short-term and medium-term impact on the lives and health of women and their children. DESIGN: A retrospective cohort study. SETTING: A tertiary maternity hospital from the southeast region of Brazil. PARTICIPANTS: The exposed population was selected from intensive care unit admissions if presenting any diagnostic criteria for SMM. Controls were randomly selected among women without SMM admitted to the same maternity and same time of childbirth. PRIMARY AND SECONDARY OUTCOME VARIABLES: Validated tools were applied, addressing post-traumatic stress disorder (PTSD) and quality of life (SF-36) by phone, and then general and reproductive health, functioning (WHO Disability Assessment Schedule), sexual function (Female Sexual Function Index (FSFI)), substance abuse (Alcohol, Smoking and Substance Involvement Screening Test 2.0) and growth/development (Denver Developmental Screening Test) of children born in the index pregnancy in a face-to-face interview. RESULTS: All instruments were applied to 638 women (315 had SMM; 323 were controls, with the assessment of 264 and 307 children, respectively). SF-36 score was significantly lower in the SMM group, while PTSD score was similar between groups. Women who had SMM became more frequently sterile, had more abnormal clinical conditions after the index pregnancy and a higher score for altered functioning, while proportions of FSFI score or any drug use were similar between groups. Furthermore, children from the SMM group were more likely to have weight (threefold) and height (1.5 fold) for age deficits and also impaired development (1.5-fold). CONCLUSION: SMM impairs some aspects of the lives of women and their children. The focus should be directed towards monitoring these women and their children after birth, ensuring accessibility to health services and reducing short-term and medium-term repercussions on physical, reproductive and psychosocial health.

Postpartum psychoactive substance abuse after severe maternal morbidity.

OBJECTIVE: To evaluate drug use among mothers during the postpartum period after a severe pregnancy-related complication. METHODS: A retrospective cohort study of maternal morbidity including maternal near-miss and control groups conducted in a tertiary hospital in Campinas, Brazil, between July 2008 and June 2012. The Alcohol, Smoking, and Substance Involvement Screening Test (ASSIST) was used to assess drug use during lifetime, pregnancy, and in the previous 3 months. RESULTS: Of 638 women evaluated, drug use was reported by 165 (25.8%). Alcohol was the most common substance used (n=133, 20.6%), followed by tobacco (n=85, 13.2%), and cocaine (n=15, 2.3%). The highest risk for postpartum drug use was among those using drugs during pregnancy. There were no differences between the morbidity and control groups, but there was a significant difference in the need for intervention to reduce alcohol consumption in the severe maternal morbidity group. Risk for substance abuse intervention increased three-fold in women with PTSD criteria, and all aspects of quality of life were worse among drug users. CONCLUSION: Drug use during pregnancy and maternal complications are linked to postpartum drug abuse. These women should be managed during pregnancy; postpartum follow-up requires updated guidance and must go beyond family planning.

Lessons from the Field Beyond the Numbers: Narratives of Professionals on Women who Experienced Severe Maternal Morbidity.

OBJECTIVE: Several factors might affect the health and the quality of life of women who had a severe maternal morbidity (SMM) or a maternal near-miss (MNM) episode. The objective of the present study was to explore the perspectives of the professionals on the repercussions of SMM or of MNM after interviewing women who survived such episodes. METHOD: Selected cases that captured the attention of professionals were reported. The professionals built individually 10 narratives, which were analyzed with the technique of content analysis. RESULTS: According to the perspectives of the professionals, women surviving a severe maternal condition and their families experienced clinical and psychosocial consequences. Some cases portrayed the intense psychological distress in mourning for the loss of the fetus or of their reproductive capacity and changes in family dynamics generating emotional overload, depression, and gender violence. CONCLUSION: The analysis of narratives may offer an idea on the complexity of the perception of care by professionals and on the need for an interdisciplinary follow-up of women surviving an SMM or an MNM episode.

OBJETIVO: Diversos fatores podem afetar a saúde e a qualidade de vida das mulheres que tiveram um episódio de morbidade materna grave (MMG) ou near-miss materno (NMM). O objetivo do presente estudo foi explorar as perspectivas dos profissionais sobre as repercussões da MMG ou do NMM após terem entrevistados mulheres que sobreviveram a um desses episódios. MéTODOS: Casos selecionados que chamaram a atenção dos profissionais foram relatados. Estes profissionais construíram individualmente 10 narrativas, que foram analisadas com a técnica de análise de conteúdo. RESULTADOS: Segundo as perspectivas dos profissionais, as mulheres que sobreviveram a uma condição materna grave e suas famílias vivenciaram consequências clínicas e psicológicas. Alguns casos relataram um intenso estresse psicológico no luto pela perda do feto ou de sua capacidade reprodutiva e de mudanças da dinâmica familiar, gerando sobrecarga emocional, depressão e violência de gênero. CONCLUSãO: A análise das narrativas pode oferecer uma ideia sobre a complexidade da percepção do cuidado de profissionais e sobre a necessidade de um seguimento interdisciplinar das mulheres sobreviventes de um episódio de MMG ou de NMM.

Drug use during pregnancy and its consequences: A nested case control study on severe maternal morbidity / Uso de drogas na gestação e suas consequências: um estudo de caso-controle aninhado sobre morbidade materna grave

Abstract Objective To assess the relationship between the use of psychoactive substances during pregnancy and the occurrence of severe maternal morbidity (SMM), perinatal outcomes and repercussions on the neuropsychomotor development of exposed children. Methods A case-control study nested within a cohort of severe maternal morbidity (COMMAG) was performed. Women with SMM were considered cases. Controls were thosewith low-risk pregnancy,without SMMand admitted during the same time period as the cases. Cohort data were collected retrospectively in hospital records for childbirth. A face-to-face interview was also performed with 638 women (323 without SMM and 315 with SMM) and their children of the index pregnancy between 6 months and 5 years after childbirth. During the interview, substance abuse during pregnancy was assessed by a modified question from the Alcohol, Smoking and Substance Involvement Screening Test 2.0 (ASSIST) and the neuropsychomotor development in the children was assessed by the Denver Developmental Screening Test, 2nd edition. Results The prevalence of licit or illicit drug use during pregnancy was ~ 17%. Among drug users, 63.9% used alcohol, 58.3% used tobacco, 9.2% used cocaine/crack and 4.6% used marijuana. There was no association between drug use during pregnancy and SMM, although tobacco use during pregnancy was associated with bleeding, presence of near-miss clinical criteria (NMCC) and alteration in infant development; alcohol use was associated with neonatal asphyxia; and cocaine/crack use was associated with the occurrence of some clinical complications during pregnancy. Conclusion The use of psychoactive substances during pregnancy is frequent and associated with worse maternal, perinatal and child development outcomes.

Resumo Objetivo Avaliar a relação entre o uso de substâncias psicoativas na gestação e a ocorrência de morbidade materna grave (MMG), resultados perinatais e repercussões no desenvolvimento neuropsicomotor das crianças expostas. Métodos Estudo de caso-controle a partir de uma coorte de morbidade materna grave (COMMAG). Mulheres com MMG foram consideradas casos. Controles foram mulheres com gestação de baixo risco, admitidas no mesmo período que os casos. Os dados da coorte foram coletados retrospectivamente em prontuários de internação para o parto e entrevistas presenciais conduzidas com 638 mulheres e seus filhos da gestação-índice, entre 6 meses e 5 anos após o parto. Na entrevista, o uso de substâncias na gestação foi avaliado com uma pergunta modificada introduzida no questionário para triagem do uso de álcool, tabaco e outras substâncias 2.0 (ASSIST, na sigla em inglês) e o desenvolvimento neuropsicomotor das crianças foi avaliado pelo teste de triagem do desenvolvimento Denver II. Resultados A prevalência do uso de drogas lícitas ou ilícitas na gestação foi de cerca de 17%. Das usuárias, 63,9% usaram álcool, 58,3% usaram tabaco, 9,2% usaram cocaína/crack e 4,6% usaram maconha. Não houve associação entre o uso de drogas na gestação eMMG. Contudo, o uso de tabaco foi associado a hemorragia, presença de critérios clínicos de near miss e alteração no desenvolvimento infantil. O uso de álcool foi associado à asfixia neonatal e o uso de cocaína/crack à ocorrência de alguma complicação clínica na gestação. Conclusão O abuso de substâncias lícitas ou ilícitas na gestação é frequente e associado a piores desfechos maternos, perinatais e do desenvolvimento infantil.

Feline gastric pneumatosis.

CASE SUMMARY: A 9-year-old male neutered domestic shorthair cat was presented with a 2 day history of anorexia and vomiting. A minimum database, including a complete blood count, serum biochemistry profile and urinalysis were unremarkable apart from a toxic neutrophilic left shift and borderline proteinuria. Abdominal ultrasound revealed intramural gas entrapment with thinning of the gastric wall, a hypoechoic pancreas, peritoneal fluid and a small volume of peritoneal gas along with a hyperechoic mesentery. CT was performed and demonstrated gas within the gastric submucosa and gas in the peritoneal cavity. Generalised gastric erythema was present at surgery and histopathology of excised abnormal areas reported gastric erosion with no obvious causative agents; however, pretreatment with dexamethasone may have been a contributing factor. Culture from biopsied gastric tissue was sterile. Clinical signs resolved after partial gastrectomy and medical management. RELEVANCE AND NOVEL INFORMATION: Feline gastric pneumatosis is a rare clinical finding. Imaging is essential for diagnosis and to decide on the appropriate treatment; this is often medical but in cases where there is suspicion or evidence of gastric perforation, surgery is indicated. To our knowledge, this is the first case of feline gastric pneumatosis secondary to gastric ulceration, diagnosed via CT and where dexamethasone may have been a contributing factor.

Post-Traumatic Stress Disorder and severe maternal morbidity: is there an association?

OBJECTIVE: To evaluate the occurrence of Post-Traumatic Stress Disorder among women experiencing a severe maternal morbidity event and associated factors in comparison with those without maternal morbidity. METHODS: In a retrospective cohort study, 803 women with or without severe maternal morbidity were evaluated at 6 months to 5 years postpartum for the presence of Post-Traumatic Stress Disorder. Interviews were conducted by telephone and electronic data was stored. Data analysis was carried out by using χ2, Fisher's Exact test, and logistic regression analysis. RESULTS: There was no significant change in the prevalence of Post-Traumatic Stress Disorder related to a previous severe maternal morbidity experience. There were also no differences in diagnostic criteria for severe maternal morbidity (hypertensive syndromes, hemorrhage, surgical intervention or intensive care unit admission required, among other management criteria). Low parity (2.5-fold risk) and increasing age were factors associated with Post-Traumatic Stress Disorder. CONCLUSIONS: A severe maternal morbidity episode is not associated with Post-Traumatic Stress Disorder symptoms within five years of the severe maternal morbidity event and birth. However, a more advanced maternal age and primiparity increased the risk of Post-Traumatic Stress Disorder. This does not imply that women who had experienced a severe maternal morbidity event did not suffer or need differentiated care.

Validation of the 36-item version of the WHO Disability Assessment Schedule 2. 0 (WHODAS 2.0) for assessing women's disability and functioning associated with maternal morbidity / Validação da versão de 36 itens do WHO Disability Assessment Schedule 2. 0 (WHODAS 2.0) para a avaliação de incapacidade e funcionalidade da mulher associada à morbidade materna

Abstract Objective To validate the translation and adaptation to Brazilian Portuguese of 36 items from the World Health Organizaton Disability Assessment Schedule 2.0 (WHODAS 2.0), regarding their content and structure (construct), in a female population after pregnancy. Methods This is a validation of an instrument for the evaluation of disability and functioning and an assessment of its psychometric properties, performed in a tertiary maternity and a referral center specialized in high-risk pregnancies in Brazil. A sample of 638 women in different postpartum periods who had either a normal or a complicated pregnancy was included. The structure was evaluated by exploratory factor analysis (EFA) and confirmatory factor analysis (CFA), while the content and relationships among the domains were assessed through Pearson's correlation coefficient. The sociodemographic characteristics were identified, and the mean scores with their standard deviations for the 36 questions of the WHODAS 2.0 were calculated. The internal consistency was evaluated byCronbach's α. Results Cronbach's α was higher than 0.79 for both sets of questons of the questionnaire. The EFA and CFA for the main 32 questions exhibited a total variance of 54.7% (Kaiser-Meyer-Olkin [KMO] measure of sampling adequacy = 0.934; p < 0.001) and 53.47% (KMO = 0.934; p < 0.001) respectively. There was a significant correlation among the 6 domains (r = 0.571-0.876), and a moderate correlation among all domains (r = 0.476-0.694). Conclusion The version of the WHODAS 2.0 instrument adapted to Brazilian Portuguese showed good psychometric properties in this sample, and therefore could be applied to populations of women regarding their reproductive history.

A estrutura foi avaliada por análise fatorial exploratória (AFE) e análise fatorial confirmatória (AFC), enquanto o conteúdo e as associações entre os domínios foram avaliados por meio do coeficiente de correlação de Pearson. Foram identificadas características sociodemográficas, e os escores médios do WHODAS 2.0 para as 36 questões foram calculados. A consistência interna foi avaliada pelo método α de Cronbach. Resultados O α de Cronbach foi maior do que 0,79 para os dois conjuntos de perguntas do questionário. A AFE e a AFC para as 32 questões apresentaram uma variância total de 54,7% (medida de adequação da amostra de Kaiser-Meyer-Olkin [KMO] = 0,934; p < 0,001) e 53,47% (KMO = 0,934; p < 0,001), respectivamente. Houve uma correlação significativa entre os 6 domínios (r = 0,571-0,876), e moderada correlação entre todos os domínios (r = 0,476-0,694). Conclusão O instrumento WHODAS 2.0, adaptado para o português do Brasil, mostrou boas propriedades psicométricas nessa amostra e, portanto, pode ser aplicado a populações de mulheres com relação à sua história reprodutiva.

Decreased calorie and protein intake is a risk factor for infection and prolonged length of stay in surgical patients: A prospective cohort study / Diminuição da ingestão de calorias e proteínas é fator de risco para infecção e internação prolongada: estudo de coorte prospectivo

ABSTRACT Objective The aim was to assess whether postoperative calorie and protein intakes increase the risk of infection and prolonged length of stay in a tertiary care university hospital in Southern Brazil. Methods This is a prospective cohort study approved by the hospital's Research Ethics Committee. The sample consisted of adult patients undergoing elective surgery. The exclusion criteria included patients who could not undergo nutritional assessment and those with a planned hospital stay of fewer than 72 hours. Nutritional status was assessed on admission and every seven days thereafter until hospital discharge or death. Demographic and clinical data, as well as information regarding independent and outcome variables, were collected from the patient's records. Food intake assessment was conducted by researchers six times a week. Calorie and protein intakes were considered adequate if equal to or greater than 75% of the prescribed amount, and length of stay was considered prolonged when above the average for specialty and type of surgery. Data was analyzed using Poisson regression. Results Of the 519 study patients, 16.2% had adequate nutritional therapy. Most of these patients were men with ischemic heart disease and acquired immunodeficiency syndrome. After adjusting for confounders, inadequate nutritional therapy increased risk of infection by 121.0% (RR=2.21; 95%CI=1.01-4.86) and risk of prolonged length of stay by 89.0% (RR=1.89; 95%CI=1.01-3.53). Conclusion Most patients did not have adequate nutritional therapy. Those with inadequate nutritional therapy had a higher risk of infection and longer length of stay.

RESUMO Objetivo Avaliar se a quantidade de calorias e proteínas ingeridas no pós-operatório aumenta o risco de infecção e de permanência hospitalar prolongada, em um hospital universitário no Sul do Brasil. Métodos Estudo de coorte prospectivo, aprovado por Comitê de Ética e Pesquisa. A amostra consistiu de adultos hospitalizados submetidos à cirurgia eletiva. Os critérios de exclusão foram pacientes que não tinham condições para avaliação do estado nutricional e aqueles com menos de 72 horas de hospitalização. O estado nutricional foi avaliado na admissão e a cada sete dias até a alta hospitalar ou óbito. Dados clínicos, demográficos, informações sobre as variáveis independentes e os desfechos, foram coletados dos prontuários. Avaliação da ingestão alimentar foi conduzida pelos pesquisadores seis vezes por semana. A quantidade de calorias e proteínas ingeridas foi considerada adequada se igual ou maior que 75% da quantidade prescrita, e permanência hospitalar foi considerada prolongada quando acima da média de acordo com a especialidade e tipo de cirurgia. Os dados foram analisados por meio de regressão de Poisson. Resultados De 519 pacientes avaliados, 16,2% tiveram adequada terapia nutricional. A maioria destes pacientes eram masculinos com doença cardíaca isquêmica e síndrome da imunodeficiência adquirida. Após ajuste para variáveis de confusão, inadequada terapia nutricional aumentou o risco de infecção em 121,0% (RR=2,21; IC95%=1,01-4,86) e o de permanência hospitalar prolongada em 89,0% (RR=1,89; IC95%=1,01-3,53). Conclusão A maioria dos pacientes não recebeu terapia nutricional adequada, aqueles sob inadequada terapia nutricional tiveram aumento do risco de infecção e permanência hospitalar prolongada.

Estratégia de proteção de patentes farmacêuticas: o caso do atazanavir / The strategy of pharmaceutical patent protection: the case of atazanavir / Estrategia de protección de patentes farmacéuticas: el caso de atazanavir

BEHAVIOR OF ADIPOKINES AFTER A YEAR FOLLOW-UP IN THE OBESITY OUTPATIENT CLINIC FOR CHILDREN AND ADOLESCENTS.

OBJECTIVE: demonstrate adipokines progression, along 12 months, in obese children and adolescents who attend the Obesity Outpatient Clinic for Children and Adolescents of the HCPA. METHODS: children and adolescents in medical treatment for obesity were followed for 12 months, assessing anthropometry, blood pressure, waist circumference, lipid profile, fasting blood sugar and insulin, inter leukine- 6, tumor necrosis factor alpha, and adiponectin in two points in time: at inclusion and after 12 months follow-up in the Obesity Outpatient Clinic for Children and Adolescents. RESULTS: 27 children and adolescents were assessed with median age of 10.3 years. The mean BMI z-scores lowered during this period (p < 0.01), HDL-c increased in the period (p = 0.025). The medians of adipokines did not vary during the period: IL-6 (p = 0.470), TNF-α (p = 0.753) and adiponectin (p = 0.943). There was no correlation of IL-6 and TNF-α with central and global obesity along the 12-months follow-up. Adiponectin increased in 45% of the sample, the increase being more pronounced in females. CONCLUSION: children and adolescents in medical treatment for obesity, after one-year follow-up, did not improve their adiponectin profile.

Objetivo: demostrar la evolución de las adipocinas a lo largo de 12 meses en niños obesos usuarios del Ambulatorio de Obesidad Infantojuvenil. Metodología: se hizo el seguimiento de niños y adolescentes en tratamiento clínico para obesidad a lo largo de 12 meses. Se los evaluó en lo tocante a antropometría, presión arterial, circunferencia de cintura, perfil lipídico, glicemia e insulina en ayuno, interleucina 6, factor de necrosis tumoral alfa y adiponectina en dos instancias: inclusión y después de 12 meses de seguimiento en el Ambulatorio de Obesidad Infantojuvenil. Resultados: se evaluaron 27 niños y adolescentes con una media de edad de 10,3 años. Los valores promedio de la puntuación-z del IMC bajaron en el período (p < 0,01), el HDL-c aumentó sus niveles en este período (p = 0,025). Las medianas de las adipocinas no variaron a lo largo del período: IL-6 (p = 0,470), TNF- (p = 0,753) y adiponectina (p = 0,943). No hubo correlación entre la IL-6 y el TNF-con obesidad central y global a lo largo de los 12 meses de seguimiento. El 45% de la muestra aumentó sus valores de adiponectina, siendo mayor este aumento en el sexo femenino. Conclusión: los niños y adolescentes en tratamiento clínico para obesidad tras un año de seguimiento no mejoraron su perfil de adipocinas.

C-reactive protein concentration in obese children followed in a pediatric/adolescent obesity clinic: changes over 12 months / Concentração de proteina C reativa em crianças obesas acompanhadas em Clínica de Obesidade Pediátrica e para Adolescentes: variações em 12 meses

Introduction: The literature provides limited information on the relationship between inflammation and obesity in the pediatric/adolescent population. Aim: To describe the changes in CRP concentration over a 12-month period and investigate whether CRP concentrations are associated with the components of MS in obese children and adolescents followed in an outpatient obesity clinic. Methods: Children and adolescents undergoing clinical treatment for obesity were studied. Assessment included anthropometric evaluation and determination of arterial blood pressure, waist circumference, lipid profile, fasting glucose and insulin, and CRP concentration at three time points: study entry (baseline), 6 months, and 12 months. Results: We evaluated 27 children and adolescents with a median age of 10.3 years. Media CRP values at the three time points were: 1.67 mg/L (0.53-3.99 mg/L), 1.42 mg/L (0.34-2.49 mg/L) and 0.97 mg/L (0.18-2.03 mg/L) (p = 0.083). We observed a reduction in blood pressure level fasting insulin, fasting glucose, HOMA and MS components, however without statistical significance. Individuals with the most marked drop in CRP also improved their lipid profile (p = 0.09) and increased HDL-c (p = 0.028). For the remaining variables, no correlation or only a weak one with the MS was observed. Conclusion: In this study with obese children and adolescents the median CRP concentration decreased over 12 months, however without statistical significance. The percentage of patients with moderate and severe inflammation also decreased. Despite the improvement in HDL and dysplipidemia in individuals with the most marked drop in CRP, an association between hsCRP and MS components was not observed.

EXPERIENCE WITH THE BRAZILIAN NETWORK FOR STUDIES IN REPRODUCTIVE AND PERINATAL HEALTH: THE POWER OF COLLABORATION IN POSTGRADUATE PROGRAMS / EXPERIÊNCIA COM A REDE BRASILEIRA DE ESTUDOS EM SAÚDE REPRODUTIVA E PERINATAL: O PODER DA COLABORAÇÃO NA PÓS-GRADUAÇÃO

The scientific collaboration in networks may be developed among countries, academic institutions and among peer researchers. Once established, they contribute for knowledge dissemination and a strong structure for research in health. Several advantages are attributed to working in networks: the inclusion of a higher number of subjects in the studies; generation of stronger evidence with a higher representativeness of the population (secondary generalization and external validity); higher likelihood of articles derived from these studies to be accepted in high impact journals with a wide coverage; a higher likelihood of obtaining budgets for sponsorship; easier data collection on rare conditions; inclusions of subjects from different ethnic groups and cultures, among others. In Brazil, the Brazilian Network for Studies on Reproductive and Perinatal Health was created in 2008 with the initial purpose of developing a national network of scientific cooperation for the surveillance of severe maternal morbidity. Since the establishment of this Network, five studies were developed, some of them already finished and others almost being completed, and two new ones being implemented. Results of the activities in this Network have been very productive and with a positive impact on not only the Postgraduate Program of Obstetrics and Gynecology from the University of Campinas, its coordinating center, but also on other participating centers. A considerable number of scientific articles was published, master´s dissertations and PhD theses were presented, and post-doctorate programs were performed, including students from several areas of health, from distinct regions and from several institutions of the whole country. This represents a high social impact taking into account the relevance of the studied topics for the country.

As colaborações científicas em rede podem ocorrer entre países, instituições acadêmicas e entre pares de pesquisadores e, uma vez estabelecidas, contribuem para a disseminação do conhecimento e estruturação da pesquisa em saúde. Diversas vantagens são atribuídas ao trabalho em rede como: a inclusão de maior número de participantes nos estudos; gerar evidências mais fortes e com maior representatividade da população (generalização secundária e validade externa); maior facilidade das publicações oriundas dos estudos serem aceitas em periódicos de impacto e abrangência; maior probabilidade de obtenção de verbas para financiamento; maior facilidade na coleta de dados sobre condições raras; inclusão de participantes de diferentes grupos étnicos e culturas, entre outras. No Brasil a Rede Brasileira de Estudos em Saúde Reprodutiva e Perinatal foi criada em 2008 com o objetivo inicial de desenvolver rede nacional de cooperação científica para vigilância da morbidade materna grave. Desde sua formação, cinco estudos foram desenvolvidos, alguns já encerrados e outros em fase de finalização, com outros dois em fase final de implantação. Os resultados das atividades desta Rede têm sido bastante produtivos e impactaram positivamente não apenas no Programa de Pós-Graduação em Tocoginecologia da Universidade Estadual de Campinas, seu centro coordenador, mas também o de outros centros participantes, uma vez que expressivo número de artigos científicos foi publicado, mestrados e doutorados foram defendidos e pós-doutorados finalizados, de alunos de diversas áreas da saúde, de diferentes regiões e de várias instituições de todo o país, com alto impacto social dada a relevância dos temas estudados para o país.

Strategies in searching homogeneity in a faculty of a postgraduate program / Estratégias na busca da homogeneidade do corpo docente de um programa de pós-graduação

The professor plays a fundamental role in a graduate program, considering he/she is who plans and performs a great part of the tasks, and he/she is also responsible for spreading knowledge among students. The professor should use didactical resources for his/her continuous qualification, being responsible for situations favoring the development of students who should learn according to the best and easier way. The homogeneity in the postgraduate program consists of having subgroups of research corresponding to the Areas of Concentration, where each subgroup works with some distinct topics of research. It is desirable that the staff of postgraduate program has a significant and high quality scientific production, homogeneously distributed among them. The professors must systematically search for resources for research in agencies supporting research, not only for sponsoring the studies, but also for adding value to the researchers involved in the whole activities. The postgraduate programs need to support the professional qualification of their staff who should improve their knowledge on epidemiology for clinical studies, ethics in research and teaching skills. Two characteristics of the postgraduate system in Brazil are the nucleation and solidarity, based on the capacity and/or interest of those more structured programs to help those beginners, cooperating with their activities. The Capes (the national governmental agency responsible for coordinating and evaluating all postgraduate programs in Brazil) valorizes the social insertion in the context of postgraduate programs´ activities. It includes the recognition of activities with technological, cultural, educational and social impact as criteria for evaluation of the programs. Does exist an ideal model of postgraduate program? We think that there is no a mathematical formulae nor an ideal model for a postgraduate program. Each institution should make adaptations and search for improvements of their faculty and students´ teams.

O docente tem importância fundamental no programa de pós-graduação, pois é quem planeja e executa grande parte das tarefas, sendo também o responsável por difundir conhecimentos aos alunos. O professor deve utilizar recursos didáticos que o qualifiquem continuamente, criando condições favoráveis para que o aluno se desenvolva e aprenda da melhor maneira e com mais facilidade. A homogeneidade no grupo de pós-graduação consiste da presença de subgrupos de pesquisa correspondentes às Áreas de Concentração, onde cada subgrupo trabalhe com algumas linhas de pesquisas diversificadas. É desejável que o corpo docente tenha significativa produção científica, de qualidade e distribuída homogeneamente entre os docentes. Estes devem sistematicamente buscar recursos em agências de fomento para pesquisa, tanto para o custeio dos estudos, quanto para a valorização dos pesquisadores envolvidos em todas as atividades. Os programas de pós-graduação precisam investir na formação de seus docentes, os quais devem aprimorar seus conhecimentos em epidemiologia de estudos clínicos, ética em pesquisa e em didática. Duas das características do sistema de pós-graduação no Brasil são a nucleação e a solidariedade, embasadas na capacidade e/ou interesse dos mais estruturados se solidarizarem com os programas iniciantes, cooperando com as suas atividades. A Capes valoriza a inserção social no contexto das atividades dos programas de pós-graduação, prevendo nos critérios de avaliação o reconhecimento de atividades com impacto tecnológico, cultural, educacional e social. Existe um modelo ideal de pós-graduação? Partimos do pressuposto de que não há uma fórmula matemática ou modelo ideal de pós-graduação e sim que cada instituição deve se adequar e buscar aperfeiçoar seu corpo docente e discente.

Emissões de óxido nitroso em águas fluviais não poluídas e poluídas da Bacia do Rio Paquequer (Teresópolis, Rio de Janeiro) / Nitrous oxide emissions from unpolluted and polluted rivers of the Paquequer Basin (Teresópolis, Rio de Janeiro)

As concentrações de N2O dissolvido e os fluxos de N2O na interface água-ar (utilizando câmaras estáticas) foram determinados ao longo do Rio Paquequer e em alguns de seus tributários. As concentrações de N2O variaram de 0,32 a 4,7 μgN.L-1, e os fluxos de N2O, de <0,56 a 141 μgN.m- 2 .h-1 . As menores concentrações e fluxos de N2O ocorreram nas cabeceiras do Rio Paquequer e do Córrego Príncipe, e a maiores, nos trechos urbanos e no Córrego Fischer. As concentrações de N2O dissolvido e os fluxos de N2O na interface água-ar foram positivamente correlacionados com a alta variabilidade nas concentrações de NH4+. Espera-se que a taxa de emissão de N2O, em massa de N, no trecho poluído do Rio Paquequer seja maior do que o valor estimado de 0,62 kgN.dia-1, uma vez que a transferência pela purga em razão da turbulência provocada por cascatas, cachoeiras e corredeiras não foi determinada.

Dissolved N2O concentrations and water-air fluxes (using floating chambers) were measured along the Paquequer River and in some tributaries. Concentrations ranged from 0.32 to 4.7 μgN.L-1 and fluxes from <0.56 to 141 μgN.m-2.h-1. The lowest N2O concentrations and fluxes were found in the headwaters of Paquequer river and in Príncipe brook, and the highest within the urban boundaries and in Fischer brook. Dissolved N2O concentrations and water-air fluxes were positively correlated with highly variable NH4+ concentrations. Mass emission rate of N2O in the polluted stretch of Paquequer River is likely to be higher than the estimate 0.62 kgN.day-1 since transfer by turbulent degassing in falls, cascades and rapids were not determined.

Is duration of postoperative fasting associated with infection and prolonged length of stay in surgical patients?

OBJECTIVE: Verify whether the postoperative fasting period increases the risk for infection and prolonged length of stay. METHODS: Prospective cohort study. Elective surgery patients were included. Excluded: those with no conditions for nutritional assessment, admitted in minimal care units, as well as with <72h in-hospital stay. Postoperative fasting was recorded from the days of no nutrition therapy. The length of stay was considered prolonged when above the average according to the specialty and type of surgery. Logistic regression was used to assess associations and adjust for confounding factors. RESULTS: 521 patients were analyzed, 44.1% were fasted for a period ≥1 day, 91% for ≥3 days and 5.6% for more than 5 days. Patients with more than 5 days fasting were more eutrophic, more admitted to intensive care units, and had more postoperative surgical complications. After adjustment for confounding variables, it was noted that ≥1 day of postoperative fasting increased the infection risk by 2.04 (CI95%: 1.20 to 3.50), ≥3 days 2.81 (CI95%: 1.4-5.8), and in fasting for more than 5 days the infection risk was 2.88 times higher (CI95%: 1.17 to 7.16). The risk for prolonged hospitalization was 2.4 (CI95%: 1.48 to 3.77) among patients who had ≥1 day fasting, 4.44 (CI95%: 2.0 to 9.8)and 4.43 times higher (CI95%: 1.73 to 11.3) among patients with ≥3 days fasting and more than 5 days, respectively. CONCLUSION: The longer duration of postoperative fasting was an independent risk factor both for infection and for prolonged hospital stay.
