Exercise of essential competencies for midwifery care by nurses in Sao Paulo, Brazil

General objective: to analyse the exercise of essential competencies for midwifery care by nurses and/or midwives in the public health system of Sao Paulo (eastern zone), Brazil. Specific objectives: to develop a profile of the public health institutions and of the nurses and/or midwives who care for women before, during and following child birth; to identify the activities performed in providing such care, as well as their frequency; and to specify the possible obstacles or difficulties encountered by them when exercising their competencies. Design: a descriptive and exploratory research design , using a quantitative approach. Setting: the study was conducted in all public health services of Sao Paulo (eastern zone), Brazil, namely 59 basic health-care units and six hospitals, during the period of October 2006-December 2007. Participants: the study population consisted of 272 nurses and/or midwives who provide care for pregnant women and newborns at the primary health-care units and maternity hospitals of the public health system. Participants comprised 100% of hospital nurse coordinators (n = 6), 61% of hospital maternity nursing and/or midwifery staff (n = 62) and 64% (n = 204) of nursing and/or midwifery staff working at primary health-care units. Methods and findings: the data collection was based on a single form given to the coordinators and two questionnaires, one handed out to antenatal and postnatal nursing and/or midwifery staff and another handed out to labour and birth nursing and/or midwifery staff. The results showed that nurses and/or midwives providing care for women during pregnancy, labour, birth and the postnatal period did not put the essential competencies for midwifery care into practice, because they encountered institutional barriers and personal resistance, and lacked protocols based on best practice and on the exercise of essential competencies needed for effective midwifery care. Key conclusions: the model of care in the public health services of Sao Paulo (eastern zone) is based much more on hierarchical positions than on professional competencies or on there commendations of the scientific community. As a result, health authorities need to review their midwifery policies to improve maternal-infant care by nurses and/or midwives in order to ensure the implementation of best midwifery practice. Practical implications: the results of this study support actions to improve the quality of care delivered to women and their families, while integrating nursing and midwifery care in Sao Paulo, Brazil.

The relationship between birth weight and insulin resistance in childhood

Chronic diseases that are typical of adulthood may originate in intra-uterine life through inadequate fetal development. The present epidemiological cohort study of 506 healthy children aged 5\20138 years evaluated the relationship between birth weight and insulin resistance in an age group that has been assessed in few similar studies. Insulin concentration was determined by chemiluminescence and insulin resistance by the homeostasis model assessment (HOMA). Blood glucose, total cholesterol and fractions (LDL cholesterol and HDL cholesterol) and TAG concentrations were determined by automated enzymatic methods. Linear regression analysis investigated the relationship between birth weight (assessed as a continuous variable and in three categories: small for gestational age, SGA; adequate for gestational age and large for gestational age) and the HOMA index, using backward stepwise selection and biological models to explain the causal pathway of the relationship. There were negativeassociations between birth weight (P < 0·001), SGA (P = 0·027) and the HOMA index, and a positive association between waist circumference (P < 0·001) and the HOMA index. Considering the significant associations between birth weight and waist circumference (P < 0·001) and waist circumference and insulin resistance (P < 0·001), we can probably suspect that lower birth weight is a common cause of higher waist circumference and insulin resistance. In summary, the results of the present study showed increased insulin resistance in apparently healthy, young children, who had lower weight at birth and higher measurements of waist circumference. There is a need to develop public health policies that adopt preventive measures to promote adequate maternal-fetal and child development and enable early diagnosis of metabolic abnormalities

Sepsis and Neutropenia in Very Low Birth Weight Infants Delivered of Mothers with Preeclampsia

Objective To study the association between maternal preeclampsia and neonatal sepsis in very low birth weight newborns. Study design We studied all infants with birth weights between 500 g and 1500 g who were admitted to 6 neonatal intensive care units of the Brazilian Network on Neonatal Research for 2 years. Exclusion criteria were major malformations, death in the delivery room, and maternal chronic hypertension. Absolute neutrophil count was performed in the first 72 hours of life. Results A total of 911 very low birth weight infants (preeclampsia, 308; non-preeclampsia, 603) were included. The preeclampsia group had significantly higher gestational age, more cesarean deliveries, antenatal steroid, central catheters, total parenteral nutrition, and neutropenia, and less rupture of membranes >18 hours and mechanical ventilation. Both groups had similar incidences of early sepsis (4.6% and 4.2% in preeclampsia and non-preeclampsia groups, respectively) and late sepsis (24% and 22.1% in preeclampsia and non-preeclampsia groups, respectively). Vaginal delivery and neutropenia were associated with multiple logistic regressions with early sepsis, and mechanical ventilation, central catheter, and total parenteral nutrition were associated with late sepsis. Death was associated with neutropenia in very preterm infants. Conclusions Preeclampsia did not increase neonatal sepsis in very low birth weight infants, and death was associated with neutropenia in very preterm infants. (J Pediatr 2010; 157: 434-8).

Implications of Extending the ADHD Age-of-Onset Criterion to Age 12: Results from a Prospectively Studied Birth Cohort

Objective: To evaluate whether including children with onset of symptoms between ages 7 and 12 years in the ADHD diagnostic category would: (a) increase the prevalence of the disorder at age 12, and (b) change the clinical and cognitive features, impairment profile, and risk factors for ADHD compared with findings in the literature based on the DSM-IV definition of the disorder. Method: A birth cohort of 2,232 British children was prospectively evaluated at ages 7 and 12 years for ADHD using information from mothers and teachers. The prevalence of diagnosed ADHD at age 12 was evaluated with and without the inclusion of individuals who met DSM-IV age-of-onset criterion through mothers` or teachers` reports of symptoms at age 7. Children with onset of ADHD symptoms before versus after age 7 were compared on their clinical and cognitive features, impairment profile, and risk factors for ADHD. Results: Extending the age-of-onset criterion to age 12 resulted in a negligible increase in ADHD prevalence by age 12 years of 0.1%. Children who first manifested ADHD symptoms between ages 7 and 12 did not present correlates or risk factors that were significantly different from children who manifested symptoms before age 7. Conclusions: Results from this prospective birth cohort might suggest that adults who are able to report symptom onset by age 12 also had symptoms by age 7, even if they are not able to report them. The data suggest that the prevalence estimate, correlates and risk factors of ADHD will not be affected if the new diagnostic scheme extends the age-of-onset criterion to age 12. J. Am. Acad. Child Adolesc. Psychiatry, 2010;49(3):210-216.

Health in Brazil 2 Maternal and child health in Brazil: progress and challenges

In the past three decades, Brazil has undergone rapid changes in major social determinants of health and in the organisation of health services. In this report, we examine how these changes have affected indicators of maternal health, child health, and child nutrition. We use data from vital statistics, population censuses, demographic and health surveys, and published reports. In the past three decades, infant mortality rates have reduced substantially, decreasing by 5.5% a year in the 1980s and 1990s, and by 4.4% a year since 2000 to reach 20 deaths per 1000 livebirths in 2008. Neonatal deaths account for 68% of infant deaths. Stunting prevalence among children younger than 5 years decreased from 37% in 1974-75 to 7% in 2006-07. Regional differences in stunting and child mortality also decreased. Access to most maternal-health and child-health interventions increased sharply to almost universal coverage, and regional and socioeconomic inequalities in access to such interventions were notably reduced. The median duration of breastfeeding increased from 2.5 months in the 1970s to 14 months by 2006-07. Official statistics show stable maternal mortality ratios during the past 10 years, but modelled data indicate a yearly decrease of 4%, a trend which might not have been noticeable in official reports because of improvements in death registration and the increased number of investigations into deaths of women of reproductive age. The reasons behind Brazil`s progress include: socioeconomic and demographic changes (economic growth, reduction in income disparities between the poorest and wealthiest populations, urbanisation, improved education of women, and decreased fertility rates), interventions outside the health sector (a conditional cash transfer programme and improvements in water and sanitation), vertical health programmes in the 1980s (promotion of breastfeeding, oral rehydration, and immunisations), creation of a tax-funded national health service in 1988 (coverage of which expanded to reach the poorest areas of the country through the Family Health Program in the mid-1990s); and implementation of many national and state-wide programmes to improve child health and child nutrition and, to a lesser extent, to promote women`s health. Nevertheless, substantial challenges remain, including overmedicalisation of childbirth (nearly 50% of babies are delivered by caesarean section), maternal deaths caused by illegal abortions, and a high frequency of preterm deliveries.

The impact of maternal cortisol concentrations on child arterial elasticity

Epidemiological studies suggest that glucocorticoid excess in the fetus may contribute to the pathophysiology of cardiovascular diseases in adulthood. However, the impact of maternal glucocorticoid on the cardiovascular system of the offspring has not been much explored in studies involving humans, especially in childhood. The objective of this study was to assess the influence of maternal cortisol concentrations on child arterial elasticity. One hundred and thirty pregnant women followed from 1997 to 2000, and respective children 5-7 years of age followed from 2004 to 2006 were included in the study. Maternal cortisol was determined in saliva by an enzyme immunoassay utilizing the mean concentration of nine samples of saliva. Arterial elasticity was assessed by the large artery elasticity index (LAEI; the capacitive elasticity of large arteries) by recording radial artery pulse wave, utilizing the equipment HDI/PulseWave CR-2000 Cardiovascular Profiling System (R). The nutritional status of the children was determined by the body mass index (BMI). Insulin concentration was assessed by chemiluminescence, and insulin resistance by the homeostasis model assessment. Blood glucose, total cholesterol and fractions (LDL-c and HDL-c) and triglyceride concentrations were determined by automated enzymatic methods. The association between maternal cortisol and child arterial elasticity was assessed by multivariate linear regression analysis. There was a statistically significant association between maternal cortisol and LAEI (P=0.02), controlling for birth weight, age, BMI and HDL-c of the children. This study suggests that exposure to higher glucocorticoid concentrations in the prenatal period is associated to lower arterial elasticity in childhood, an earlier cardiovascular risk marker.

Congenital eruption cyst: a case report

Congenital pathologies are those existing at or dating from birth. Occurrence of congenital cystic lesions in the oral cavity is uncommon in neonates. Eruption cyst (EC) is listed among these unusual lesions. It occurs within the mucosa overlying teeth that are about to erupt and, according to the current World Health Organization (WHO) classification of epithelial cysts of the jaws, EC is a separate entity. This paper presents a case of congenital EC successfully managed by close monitoring of the lesion, without any surgical procedure or tooth extraction. Eruption of the teeth involved, primary central incisors, occurred at the fourth month of age. During this time neither the child nor mother had any complication such as pain on sucking, refusal to feed, airway obstruction, or aspiration of fluids or teeth.

Oral findings and dental care in a patient with myelomeningocele: case report of a 3-year-old child

Myelomeningocele (MMC) is a congenital malformation of the neural tube that occurs in the first weeks of pregnancy. This malformation refers to the caudal non-closure of the neural tube and neural tissue exposure, which lead to neurological problems, such as hydrocephalus, motor disability, genitourinary tract and skeletal abnormalities and mental retardation. Patients with MMC have an acknowledged predisposition to latex allergy and are usually at a high caries risk and activity due to poor oral hygiene, fermentable carbon hydrate-rich diet and prolonged use of sugar-containing medications. This paper addresses the common oral findings in pediatric patients with MMC, discusses the strategies and precautions to deal with these individuals and reports the dental care to a young child diagnosed with this condition.

Caracterização das mães, partos e recém-nascidos em Campinas, São Paulo, 2001 e 2005

OBJETIVO: Comparar dados pré-natais, dos partos e dos recém-nascidos de Campinas em 2001 e 2005. MÉTODOS: Estudo transversal que analisou 13.656 documentos do Sistema de Informações sobre Nascidos Vivos (Sinasc) de 2005, comparando-as aos resultados de 2001. Analisou-se o local de moradia e parto, idade materna, estado civil, escolaridade, ocupação, paridade, consultas de pré-natal, tipo de parto, duração da gestação e peso ao nascer. Para avaliar a associação entre as variáveis, utilizou-se o teste de qui-quadrado, sendo significante p<0,05. RESULTADOS: Os nascidos nos Distritos de Saúde (DS) com piores índices de condições de vida (ICV) diminuíram em relação a 2001. A taxa de adolescentes passou de 17,7% para 14,7%. Em 2001, 39,4% das mães trabalhavam e, em 2005, 42,9%. Quanto à presença de companheiro, 35,9 e 54,3% não o referiam em 2001 e 2005, respectivamente. A escolaridade passou de 37,8% de mães com até sete anos de estudo para 25,7%, com aumento das que estudaram entre oito e 11 anos e 12 anos ou mais. O comparecimento a mais de seis consultas no pré-natal passou de 74,4 para 86,6%. Houve aumento de cesáreas (54,9 para 60,3%) e de prematuridade (7,1 para 8,9%). Não houve alteração no perfil de peso ao nascimento. CONCLUSÕES: Verificou-se queda da paridade nos DS com piores ICV e no percentual de mães adolescentes. Elevou-se o número de trabalhadoras, mulheres sem companheiro, escolaridade e frequência ao pré-natal.

Litter size, effects of maternal body size, and date of birth in South American scorpions (Arachnida: Scorpiones)

We present new data on litter size and date of birth (month) for 21 South American scorpions species. We provide data for one katoikogenic species, the liochelid Opisthacanthus cayaporum Vellard, 1932 (offspring = 3; birth month: Jan); and for several apoikogenic species, such as the bothriurids Bothriurus araguayae Vellard, 1934 (53; Sep), B. rochensis San Martín, 1965 (22-28; Jan, Aug); the buthids Ananteris balzanii Thorell, 1891 (10-34; Jan-Mar), Physoctonus debilis (Koch, 1840) (2; Sep), Rhopalurus amazonicus Lourenço, 1986 (19; Nov), R. lacrau Lourenço & Pinto-da-Rocha, 1997 (30; Dec), R. laticauda Thorell, 1876 (41; Nov), R. rochai Borelli, 1910 (11-47; Dec-Jan, Mar-Apr), Tityus bahiensis (Perty, 1833) (4-23; Oct-Mar), T. clathratus Koch, 1844 (8-18; Nov-Jan), T. costatus (Karsch, 1879) (21-25; Jan, Apr), T. kuryi Lourenço, 1997 (4-16; Mar), T. mattogrossensis Borelli, 1901(8-9; May), T. obscurus (Gervais, 1843) (16-31; Jan-Feb, May, Jul), T. serrulatus Lutz & Mello, 1922 (8-36; Dec, Feb-Apr), T. silvestris Pocock, 1897 (5-14; Dec-Jan, Apr), T. stigmurus (Thorell, 1876) (10-18; Nov, Jan, Mar), Tityus sp. 1 (T. clathratus group - 7-12; Feb-Apr), Tityus sp. 2 (T. bahiensis group - 2; Mar); and the chactid Brotheas sp. (8-21; Jan, Apr). We observed multiple broods: R. lacrau (offspring in the 2nd brood = 27), T. kuryi (6-16), T. obscurus (2-32), T. silvestris (8), T. stigmurus (4-9), T. bahiensis (offspring in the 2nd brood = 2-18; 3rd = 1), and T. costatus (2nd brood = 18; 3rd = 4). We found statistically significant positive correlation between female size and litter size for T. bahiensis and T. silvestris, and nonsignificant correlation for T. serrulatus.

Investimento materno e história reprodutiva de mães residentes em contextos com diferentes graus de urbanização

A presente pesquisa tem como objetivo caracterizar o investimento materno e a história reprodutiva de mães que vivem em diferentes contextos. Para tal, 150 mães que residiam em três contextos com diferentes graus de urbanização foram entrevistadas. Por meio da análise estatística dos dados constatou-se que houve diferenças significativas entre os contextos, além de correlações positivas entre os núcleos reprodutivos, como idade da primeira relação sexual e idade da mãe no nascimento do primeiro filho. Conclui-se que as estratégias reprodutivas são influenciadas pela história de vida das mães, das condições sociodemográficas atuais e do contexto onde vivem.

A menina mãe: incesto e maternidade

Trata-se de um estudo de caso de uma adolescente de quinze anos, vítima de incesto perpetrado pelo padrasto, que teve como consequência sua gravidez e o nascimento de uma criança. O principal objetivo é discutir a reorganização familiar da adolescente, seu silêncio e o de sua família em relação ao abuso sexual. O contexto de pesquisa foi o Centro de Referência em Assistência Social (CRAS) de uma cidade de periferia. O método utilizado foi a observação participante. A organização das informações possibilitou construir Zonas de Sentido que se constituem em indicadores de vulnerabilidade: sua relação com a violência sofrida; sua relação com a família; sua relação com a filha e sua relação com a escola. Nesse caso, o silêncio, o isolamento e a migração para outra cidade foram opções de proteção. O estudo da gravidez nesta circunstância requer uma compreensão particularizada em relação ao estudo de adolescentes grávidas em geral.

Cobertura vacinal em menores de dois anos a partir de registro informatizado de imunização em Curitiba, PR

OBJETIVO: Avaliar o programa de imunização de crianças de 12 e de 24 meses de idade, com base no registro informatizado de imunização. MÉTODOS: Estudo descritivo em amostra probabilística de 2.637 crianças nascidas em 2002 e residentes em Curitiba, PR. As fontes de dados foram: registro informatizado de imunização do município, Sistema de Informação de Nascidos Vivos e inquérito domiciliar para casos com registro incompleto. As coberturas foram estimadas aos 12 e aos 24 meses de vida e analisadas segundo características socioeconômicas de cada distrito sanitário e o vínculo das crianças aos serviços de saúde. Foram analisadas a abrangência, completude e duplicidades do registro informatizado de imunização. RESULTADOS: A cobertura do esquema de imunização foi de 95,3% aos 12 meses sem diferenças entre os distritos e de 90,3% aos 24 meses, tendo sido mais elevada em um distrito com piores indicadores socioeconômicos (p = 0,01). A proporção de vacinas, segundo o tipo, aplicadas antes e após a idade recomendada foi de até 0,9% e até 32,2%, respectivamente. A cobertura do registro informatizado de imunização foi de 98% na amostra estudada, o sub-registro de doses de vacinas foi de 11% e a duplicidade de registro foi de 20,6%. Os grupos que apresentaram maiores coberturas foram: crianças com cadastro definitivo, aquelas com três ou mais consultas pelo Sistema Único de Saúde e as atendidas em Unidades Básicas de Saúde que adotam plenamente a Estratégia de Saúde da Família. CONCLUSÕES: A cobertura vacinal em Curitiba mostrou-se elevada e homogênea entre os distritos, e o vínculo com os serviços de saúde foi fator importante para tais resultados. O registro informatizado de imunização mostrou-se útil no monitoramento da cobertura vacinal; no entanto, é importante a prévia avaliação do seu custo-efetividade para que seja amplamente utilizado pelo Programa Nacional de Imunização.

MÉTODOS: Estudo transversal envolvendo 566 crianças matriculadas em escolas particulares no município de São Paulo, SP, 2004-2005. A variável dependente foi sobrepeso e obesidade. Para a classificação do estado nutricional das crianças foram utilizadas as curvas de percentis do Índice de Massa Corporal para idade, classificando como sobrepeso valores e"P85 e

Insegurança alimentar, vínculo mãe-filho e desnutrição infantil em área de alta vulnerabilidade social

OBJETIVO: analisar a insegurança alimentar e o vínculo inadequado mãe-filho como dois potenciais determinantes da desnutrição em crianças de quatro a seis anos de idade. MÉTODOS: estudo de caso-controle desenvolvido em Escolas Municipais de Educação Infantil (EMEIs) no Jardim Jaqueline, área de alta vulnerabilidade social do município de São Paulo, Brasil. Foram aplicados a Escala Brasileira de Insegurança Alimentar e o Protocolo de Avaliação do Vínculo Mãe-filho, além de coletadas informações biológicas e socio-econômicas. Para verificação dos efeitos de cada variável independente e controle dos efeitos das demais variáveis incluídas no modelo, foi utilizado o modelo de regressão logística múltipla. RESULTADOS: verificou-se que tanto a insegurança alimentar familiar (OR=3,6) como o vínculo inadequado mãe-filho (OR=9,4) estiveram associados com a desnutrição infantil (p<0,05), mesmo após o controle para o peso ao nascimento da criança e idade, estado conjugal e trabalho maternos. CONCLUSÕES: tanto a insegurança alimentar familiar (OR=3,6) como o vínculo mãe-filho inadequado (OR=9,4) mostraram-se fatores determinantes da ocorrência da desnutrição na população estudada.
