INTRODUÇÃO: Crianças nascidas pequenas para a idade gestacional (PIG) possuem risco aumentado de apresentar baixa estatura na vida adulta. O benefício do tratamento com rhGH (recombinant human growth hormone) está bem estabelecido nas crianças nascidas PIG e com inadequação do catch up de crescimento, sendo importante estudar as variáveis preditoras de ganho estatural nesses indivíduos. OBJETIVO: Avaliar resposta terapêutica e variáveis clínicas associadas à recuperação do crescimento em dois anos de tratamento com rhGH em um grupo de crianças nascidas PIG. MÉTODOS: Foram selecionadas 35 crianças nascidas PIG em uso de rhGH há pelo menos dois anos e avaliadas as seguintes variáveis: sexo, idade gestacional, SDS de peso ao nascimento, SDS de comprimento ao nascimento, índice ponderal ao nascimento, idade cronológica no início do tratamento, SDS de estatura-alvo, dose de rhGH, relação entre idade óssea e idade cronológica, delta SDS de IGF-I. RESULTADOS: A média do SDS de estatura teve um incremento significante de 0,55 SDS (p < 0,01) e 0,86 SDS (p < 0,01), no primeiro e segundo anos de tratamento com rhGH, respectivamente. A dose de rhGH foi identificada como preditora de ganho estatural após um ano de tratamento, enquanto o SDS de comprimento ao nascimento e a idade gestacional se mostraram preditoras de crescimento após dois anos de rhGH. CONCLUSÃO: Foi confirmada uma resposta de crescimento positiva ao tratamento com rhGH nas crianças nascidas PIG sem catch up de crescimento nos primeiros dois anos de vida. A avaliação de características individuais ao nascimento e ao início do rhGH, assim como a identificação das variáveis preditoras do crescimento, são importantes na decisão e otimização do tratamento / INTRODUCTION: Children born small for gestational age (SGA) are at increased risk for short stature in adulthood. Treatment benefits with rhGH (recombinant human growth hormone) is well established in children born SGA and inadequate growth catch up, therefore it is very importante to study height gain predictors in these individuals. OBJECTIVE: To evaluate therapeutic response and clinical variables associated with growth recovery in two years of rhGH treatment in a group of children born SGA. METHODS: Thirty-five children born SGA in use of rhGH for at least two years were selected and the following variables were evaluated: gender, gestational age, birth weight SDS, birth length SDS, birth weight index, chronological age at the beginning of treatment, target-height SDS, rhGH dose, chronological age and bone age relation, and delta IGF-I SDS. RESULTS: The mean height SDS had a significant increase of 0.55 SDS (p < 0.01) and 0.86 SDS (p < 0.01) in the first and second year of treatment with rhGH, respectively. The rhGH dose was identified as a height gain predictor after one year of treatment, while birth length SDS and gestational age were predictors of growth gain after two years of rhGH. CONCLUSION: A positive growth response to rhGH treatment was confirmed in children born SGA with no growth catch up in their first two years of life. Evaluation of individual characteristics at birth and in the beginning of rhGH treatment, as well as the identification growth predictors, are important for the decision and treatment optimization

A gemelaridade apresenta algumas intercorrências específicas, como a discordância de peso entre fetos e recém-nascidos (RNs). O objetivo do presente estudo foi predizer a discordância de peso do exame ultra-sonográfico comparada à do parto e avaliar a morbidade e a mortalidade neonatais nas gestações gemelares discordantes quanto ao peso. Este foi um estudo retrospectivo, com levantamento dos casos do período de 1998 a 2004, no Setor de Gestações Múltiplas da Clínica Obstétrica do HCFMUSP. Na avaliação da predição ultra-sonográfica, foram inseridas 221 gestações gemelares e, na avaliação da morbidade e da mortalidade, 151 gestações com partos nessa instituição. A discordância de peso foi definida como >= 20%, sendo excluídos os casos de malformações fetais (n=43) e da Síndrome da transfusão feto-fetal (n=24). Para análise da adequação do peso ao nascimento, utilizou-se a curva de Alexander et al., 1998, para gêmeos. No estudo da predição, foram utilizados quatro intervalos de tempo em relação ao parto (0 a 7 dias - n = 96; 8 a 14 dias - n = 66; 15 a 21 dias - n = 58; 22 a 28 dias - n = 59 gestações), somando 279 avaliações. No grupo de 0 a 7 dias, a estimativa da sensibilidade foi de 93,6%, especificidade de 79,4%, valor preditivo positivo de 89,2%, valor preditivo negativo de 87,1% e acurácia de 88,6%. Nos demais grupos, a sensibilidade e a acurácia foram de 95,8% e 84,9%, 95,6% e 84,5%, 90,9% e 84,8%, respectivamente. Em relação à morbidade, 111 gestações eram concordantes (73,5%) e 40 discordantes quanto ao peso. No grupo discordante, 75% das gestações gemelares apresentaram pelo menos um recém-nascido com Restrição de Crescimento Fetal (RCF). Nesta análise, as gestações gemelares concordantes monocoriônicas obtiveram menor média de idade gestacional no parto (34,3 versus 36,2 semanas, p=0,004), menor peso médio (2067 versus 2334 gramas, p=0,0016) e maior tempo de internação (10,6 versus 7,3 dias, p=0,0023) que as gestações concordantes dicoriônicas. Nas gestações discordantes, não houve diferença significativa em relação à corionicidade. As gestações discordantes, com pelo menos um RN abaixo do percentil 10, apresentaram menor média de idade gestacional (35,2 versus 36,8 semanas, p=0,009) e maior tempo de internação (17,5 versus 8,2 dias, p=0,026). Não foi observada diferença significativa de morbidade e mortalidade entre RNs concordantes e discordantes, com pesos entre os percentis 10 e 90. Os fetos menores das gestações discordantes demonstraram maior freqüência de índice de Apgar inferior a 7 (27,5% versus 7,5%, p=0,01). A avaliação da mortalidade não demonstrou diferença significativa em relação aos grupos concordantes (3,7%) e discordantes (4,5%; p = 1,00). No presente estudo, conclui-se que os quatro grupos apresentaram adequada correlação entre a discordância de peso à ultra-sonografia e no nascimento, porém com melhor predição até sete dias antes do parto. A morbidade neonatal esteve relacionada à RCF do menor feto. A discordância de peso e a corionicidade não interferiram na mortalidade neonatal. / The aim of this study was to evaluate the ability of prenatal ultrasound scans to predict fetal growth discordance in twin pregnancies and perinatal morbidity/mortality associated with these cases. This was a retrospective study (1998-2004) involving twin pregnancies that were scanned and had their delivery at our Institution (HCFMUSP). Cases with fetal malformations (n=43) or twin to twin transfusion syndrome (n=24) were excluded. The study of ultrasound scans consisted of 221 twin pregnancies. The final morbidity/mortality study group consisted of 151 twin pregnancies. Birth weight was evaluated based on twin growth charts published by Alexander et al (1998) and weight discordance as a difference >= 20%. Small for gestacional age (SGA) was defined as birth weight below the 10th centile. The study of ultrasonographic prediction of interwin discordance was made using four different intervals between ultrasound examination and delivery (0 to 7 days, n = 96; 8 to 14 days, n = 66; 15 to 21 days, n = 58; 22 to 28 days, n = 59 pregnancies), with a total of 279 ultrasound examinations. In group 0 to 7 days, the sensitivity was 93,6%, specificity was 79,4%, positive predicted values was 89,2%, negative predicted values was 87,1% and accuracy was 88,6%. In the groups 8 to 14 days, 15 to 21 days and 22 to 28 days the sensitivity and accuracy were 95,8% and 84,9%, 95,6% and 84,5%, 90,9% and 84,8%, respectively. Birthweight discordance was observed in 40 sets of twins (26.5%) and 12 cases were monochorionic MC (30%). Twenty five cases (22.5%) in the non discordant group were MC. In the non discordant group, monochorionic pregnancies showed lower gestational age at delivery (34.3 versus 36.2 wks, p=0.004), lower mean birth weight (2067g versus 2334g, p=0.0016) and longer length of stay in hospital (10.6 versus 7.3 days, p=0.0023) compared to dichorionic twins. In the group with twin birthweight discordance, there were no significant differences between MC and DC pregnancies and 75% of the cases had at least one newborn with SGA. These cases were showed lower gestational age at delivery (35.2 versus 36.8wks, p=0.009) and longer length of stay in hospital (17.5 versus 8.2 days, p=0.026). In the discordant group, the smaller twin had a higher frequency of first minute Apgar score < 7 (27.5% versus 7.5%, p=0.01). Perinatal mortality rate was similar in both groups (discordant 4.5% and concordant 3.7%, p=1.0). There were no significant differences in morbidity and mortality between concordant and discordant twins when birth weight was between the 10 th and 90 th centile. In conclusion, there was a good correlation between fetal growth discordance predicted by prenatal scan and actual birth weight discordance. Neonatal morbidity was related to SGA. Excluding fetal malformation and TTTS cases, birth weight discordance in twin pregnancies is not a significantly associated with neonatal mortality.

<p>Kangaroo mother care (KMC) was first initiated in Colombia due to shortages of incubators and the incidence of severe hospital infections of new-born infants during hospital stay (Feldman, 2004). Currently it is identified by UNICEF as a universally available and biologically sound method of care for all new-borns, particularly for low birth weight infants (Department of Reproductive Health and Research, 2003) in both developed and developing countries. The Western Cape Provincial Government implemented a policy on KMC as part of their strategy to decrease the morbidity and mortality of premature infants in 2003 (Kangaroo Mother Care Provincial task team, 2003). Essential components of KMC are: skin-to-skin contact for 24 hours per day (or as great a part of the day as possible), exclusive breastfeeding and support to the motherinfant dyad. Successful implementation of KMC requires relevant education of nurses, education of mothers on KMC by nursing staff, monitoring of the implementation of KMC by nurses, planning for a staff mix with varying levels of skill and experience with KMC, the identification of institution specific barriers to the implementation of KMC, and the implementation of institution specific strategies to overcome these barriers (Wallin,et al., 2005 / Bergman &amp / Jurisco, 1994 / Cattaneo, et al., 1998). This study aims to determine the knowledge of and attitude towards kangaroo mother care, of nursing staff and kangaroo mothers in the Eastern sub-district of Cape Town.</p>

Background Reproductive health and health events associated with pregnancy including induced abortions are among the most important factors for the health of fertile women. Adverse outcomes have an impact on women’s reproductive health and their overall health as well as the health of their offspring. Pregnancy and child bearing take place within a cultural context. Risk factors for adverse pregnancy outcomes depend on factors both associated with the individual woman as well as contextual factors. Aims This thesis investigates reproductive health indicators and their determinants for women in a rural district in Vietnam with special focus on adverse pregnancy outcomes and their determinants. In addition, this thesis explores the perspectives and experiences among pregnant women and health care professionals on maternal health care in Vietnam and risks during pregnancy and delivery. Methods The studies used quantitative and qualitative methods.  In the quantitative studies a total of 4,396 women reporting 5,838 pregnancies, and 5,521 infants were included. Parametric and non parametric tests and univariate and multivariate logistic regression analysis was performed.   For the estimation of small for gestational age a population-specific reference curve was constructed based on the mean birth weight at term in the study population. In the qualitative studies data were collected from eight focus group discussions, four with pregnant women and four with health care professionals. Manifest and latent content analysis was applied.  Main findings Women belonging to an ethnic minority or women giving birth at home were at increased risk of stillbirth.  The risk of induced abortion increased with maternal age. Neonatal mortality was estimated to 11.6 per 1000 live births and perinatal mortality to 25.0 per 1000 births. The prevalence of small for gestational age was estimated to 6.4%. Risk factors for small for gestational age included women in farming occupations and post-term birth. There was a marked decrease in perinatal mortality after 33 weeks of gestation. Contextual conditions influenced both pregnant women’s use of maternal health care and the performance of the health care professionals. The use of maternal health care was influenced by economical conditions as well as cultural norms that impeded women’s autonomy. Structural constraints included inadequate financing of the health system, including lack of staff, insufficient professional re-training, and inadequate equipment. Pregnant women in rural Vietnam created a strategy to promote a healthy pregnancy through lifestyle adjustments, gathering of information, and seeking timely medical care. Insights in pregnancy-related conditions were sought from various sources and were influenced both by Vietnamese traditions and modern medical knowledge. Conclusions Knowledge about pregnancy complications and their related signs and symptoms, and a high confidence in the maternal health care probably contribute to the relatively good maternal health status and pregnancy outcomes in Vietnam. To improve perinatal and neonatal outcomes there is a need to ensure access for all pregnant women to delivery units with surgical capacity in case of an obstetrical emergency. Also, a higher proportion of premature infants need to be born at units with access to neonatal care. This may be achieved by an improved system for referral including capacity of medical care during transportation. Other desirable improvements include antenatal identification of small for gestational age foetuses. In our study the induced abortion rate increased with maternal age and was highest among married women, indicating that induced abortions may be used as a method for family planning. The cultural norms in Vietnam limit women’s autonomy and reduce their possibility to make independent decisions about their reproductive health. Our studies emphasize the importance of adequate access for all women to maternal health care adjusted for their individual needs. A better understanding is needed of context-specific factors that influence couples’ choice of family planning methods, place of birth, and maternal health care. The communication between pregnant women and health care professionals needs further investigation. This knowledge is essential in order to develop reproductive health services that are accessible, acceptable and affordable to all.

Background: The role of the placenta in fetal programming has been recognized as a highly significant, yet often neglected area of study. We investigated placental size in relation to psychopathology, in particular attention deficit hyperactivity disorder (ADHD) symptoms, in children at 8 years of age, and later as adolescents at 16 years. Methodology/Principal Findings: Prospective data were obtained from The Northern Finland Birth Cohort (NFBC) 1986. Placental weight, surface area and birth weight were measured according to standard procedures, within 30 minutes after birth. ADHD symptoms, probable psychiatric disturbance, antisocial disorder and neurotic disorder were assessed at 8 years (n = 8101), and ADHD symptoms were assessed again at 16 years (n = 6607), by teachers and parents respectively. We used logistic regression analyses to investigate the association between placental size and mental health outcomes, and controlled for gestational age, birth weight, socio-demographic factors and medical factors, during gestation. There were significant positive associations between placental size (weight, surface area and placental-to-birth-weight ratio) and mental health problems in boys at 8 and 16 years of age. Increased placental weight was linked with overall probable psychiatric disturbance (at 8y, OR = 1.14 [95% CI = 1.04-1.25]), antisocial behavior (at 8 y, OR = 1.14 [95% CI = 1.03-1.27]) and ADHD symptoms (inattention-hyperactivity at 16y, OR = 1.19 [95% CI = 1.02-1.38]). No significant associations were detected among girls. Conclusions/Significance: Compensatory placental growth may occur in response to prenatal insults. Such overgrowth may affect fetal development, including brain development, and ultimately contribute to psychopathology.

Introduction: Prenatal exposure to polycyclic aromatic hydrocarbons (PAH) and to acrylamide has been suggested to reduce fetal growth. The role of diet, the main source of exposure to these compounds in the general population, remains uncertain. This thesis aimed to characterize women’s exposure during pregnancy to dietary acrylamide and the genotoxic PAH benzo(a)pyrene [B(a)P], and to assess the effects of prenatal exposure to these compounds on fetal growth indicators. Methods: This thesis was done within two large European population-based cohort studies conducted in Spain and Norway: the INfancia y Medio Ambiente (INMA; n=657) and The Norwegian Mother and Child Cohort (MoBa; n=50651). Dietary B(a)P and acrylamide intakes were estimated based on information from food frequency questionnaires and the concentrations of these compounds in foods. Results: (i) Smokers had higher dietary intakes of B(a)P and acrylamide compared to non-smokers; (ii) the main predictors of B(a)P intake were shellfish and processed/cured meats while the main predictors of acrylamide intake were snacks, fried potatoes, and crisp bread; (iii) higher prenatal exposure to dietary B(a)P and acrylamide may reduce birth weight and increase the risk of small for gestational age, independently of smoking-related exposure and (iv) stronger effects of dietary B(a)P on fetal growth were observed among women with low vitamin C intake. Conclusions: Dietary B(a)P and acrylamide intakes during pregnancy may impair fetal growth. Therefore, reducing the intake of these compounds from the diet should be recommended in dietary guidelines for pregnant women. Likewise, increasing intakes of fruits and vegetables rich in vitamin C should be recommended given its potential to prevent adverse effects from exposure to such contaminants. / Introducción: La exposición prenatal a los hidrocarburos aromáticos policíclicos (HAP) y a la acrilamida ha sido asociada con la reducción del crecimiento fetal. El papel de la dieta, la principal fuente de exposición a estos compuestos en la población general, sigue siendo incierto. Los objetivos de esta tesis son caracterizar la exposición a través de la dieta a la acrilamida y a los HAP, específicamente el compuesto genotóxico benzo(a)pireno [B(a)P], durante el embarazo, y evaluar los efectos de la exposición prenatal a estos compuestos sobre indicadores del crecimiento fetal. Métodos: Esta tesis se realizó dentro del marco de dos grandes estudios europeos de cohortes de base poblacional realizados en España y Noruega: INfancia y Medio Ambiente (INMA; n=657) y The Norwegian Mother and Child Cohort (MoBa; n=50651). La ingesta de B(a)P y acrilamida fue estimada a partir de información de cuestionarios de frecuencia alimentaria y las concentraciones de estos compuestos en los alimentos. Resultados: (i) Las fumadoras tuvieron mayor ingesta de B(a)P y acrilamida a través de la dieta en comparación con las no fumadoras; (ii) los principales predictores de la ingesta de B(a)P fueron los mariscos y los embutidos, mientras que los principales predictores de la ingesta de acrilamida fueron los aperitivos, las patatas fritas y el pan crujiente; (iii) la exposición prenatal al B(a)P y la acrilamida pueden reducir el peso al nacer y aumentar el riesgo de pequeño para la edad gestacional, independientemente de la exposición relacionada con el tabaco y (iv) los efectos de la ingesta de B(a)P a través de la dieta sobre el crecimiento fetal fueron más fuertes entre las mujeres con baja ingesta de vitamina C. Conclusiones: La ingesta de B(a)P y acrilamida a través de la dieta durante el embarazo, puede perjudicar el crecimiento fetal. Consecuentemente, recomendaciones para la reducción de la ingesta de estos compuestos a través de la dieta deberían ser incluidas en las guías dietéticas para mujeres embarazadas. Asimismo, debería recomendarse un aumento en la ingesta de frutas y verduras con alto contenido en vitamina C por su potencial para prevenir efectos relacionados con la exposición a estos contaminantes.

Nutritional status during pregnancy and the effects of nutritional deficiencies on pregnancy outcomes following bariatric surgery is an important issue that warrants further study. Objective: To investigate pregnancy outcomes and nutritional indices following restrictive and malabsorptive procedures. Setting: University Hospital, Greece. Methods: We investigated pregnancy outcomes of 113 women who gave birth to 150 children following biliopancreatic diversion (BPD), Roux-en-Y gastric bypass (RYGB) and sleeve gastrectomy (SG) between June 1994 and December 2011. Biochemical indices and pregnancy outcomes were compared among the different types of surgery and to overall 20-year hospital data, as well as to 56 pre-surgery pregnancies in 36 women of the same group. Results: Anemia was observed in 24.2% and 15.6% of pregnancies following BPD and RYGB, respectively. Vitamin B12 levels decreased postoperatively in all groups, with no further decrease during pregnancy; however, low levels were observed not only after BPD (11.7%) and RYGB (15.6%), but also after SG (13.3%). Folic acid levels increased. Serum albumin levels decreased in all groups during pregnancy, but hypoproteinemia was seen only after BPD. Neonates after BPD had significantly lower average birth weight without a higher frequency of low birth weight defined as less than 2500gr. A comparison of neonatal data between babies born before surgery (BS) and siblings born after surgery (AS) showed that AS newborns had lower average birth weight with no significant differences in body length or head circumference and no cases of macrosomia. Conclusions: Our study showed reasonably good pregnancy outcomes in this sample population following all types of bariatric surgery provided nutritional supplement guidelines are followed. Closer monitoring is required in pregnancies following malabsorptive procedures especially regarding protein nutrition. / Η θρεπτική κατάσταση κατά τη διάρκεια της εγκυμοσύνης και οι συνέπειες διατροφικών ανεπαρκειών στην έκβαση της, που ακολουθεί μια χειρουργική επέμβαση για κλινική σοβαρή παχυσαρκία αποτελεί θέμα που χρήζει περαιτέρω έρευνας. Σκοπός της συγκεκριμένης μελέτης ήταν η διερεύνηση της θρεπτικής κατάστασης και της έκβασης της εγκυμοσύνης, τόσο στις μητέρες όσο και στα νεογνά, σε γυναίκες που είχαν υποβληθεί στο παρελθόν σε περιοριστικές και δυσαπορροφητικές επεμβάσεις για κλινικά σοβαρή παχυσαρκία. Μελετήθηκαν 113 γυναίκες που γέννησαν 150 παιδιά μετά από χολοπαγκρεατική εκτροπή (BPD), Roux-en-Y γαστρική παράκαμψη (RYGB) και επιμήκη γαστρεκτομή μεταξύ Ιουνίου 1994 και Δεκεμβρίου 2011. Συγκρίθηκαν τα αποτελέσματα των θρεπτικών δεικτών και της έκβασης της εγκυμοσύνης μεταξύ των επεμβάσεων καθώς και με τα 20ετή στοιχεία γεννήσεων του νοσοκομείου μας και τα αποτελέσματα από 56 προεγχειρητικές εγκυμοσύνες σε 36 από τις ίδιες γυναίκες. Αναιμία παρατηρήθηκε σε 24.2% και 15.6% των κυήσεων μετά από BPD και RYGB, αντίστοιχα. Τα επίπεδα της βιταμίνης B12 μειώθηκαν μετεγχειρητικά σε όλες τις ομάδες, χωρίς περαιτέρω μείωση κατά τη διάρκεια της εγκυμοσύνης• όμως, χαμηλά επίπεδα παρατηρήθηκαν σε κάποιες γυναίκες όχι μόνο μετά από BPD (11.7%) και RYGB (15.6%), αλλά και μετά από SG (13.3%). Τα επίπεδα του φυλλικού οξέος αυξήθηκαν μετεγχειρητικά και κατά τη διάρκεια της εγκυμοσύνης. Η τιμή της αλβουμίνης μειώθηκε σε όλες τις ομάδες κατά τη διάρκεια της εγκυμοσύνης, αλλά υποπρωτεϊναιμία παρατηρήθηκε μόνο μετά από BPD. Τα νεογνά μετά από BPD είχαν χαμηλότερο μέσο όρο βάρους γέννησης (p<0.05), χωρίς να υπάρχει μεγαλύτερη συχνότητα χαμηλού βάρους γέννησης (<2500gr). Η σύγκριση μεταξύ των νεογνών που γεννήθηκαν πριν και μετά το χειρουργείο έδειξε ότι τα νεογνά που γεννήθηκαν μετά είχαν χαμηλότερο βάρος (p<0.001) χωρίς σημαντικές διαφορές στη διάρκεια κύησης, στο μήκος ή στην περίμετρο της κεφαλής και καθόλου μακροσωμία. Συμπερασματικά, η δική μας μελέτη έδειξε σχετικά καλή θρεπτική κατάσταση και έκβαση στη εγκυμοσύνη μετά από όλους τους τύπους επεμβάσεων στη συγκεκριμένη πληθυσμιακή ομάδα εφόσον υπάρχει συστηματική παρακολούθηση και ακολουθούνται οι διατροφικές οδηγίες. Πιο στενή παρακολούθηση χρειάζεται μετά από δυσαπορροφητικές επεμβάσεις ιδιαίτερα ως προς το θέμα της πρωτεϊνικής θρέψης

Successful implementation of KMC requires relevant education of nurses, education of mothers on KMC by nursing staff, monitoring of the implementation of KMC by nurses, planning for a staff mix with varying levels of skill and experience with KMC, the identification of institution specific barriers to the implementation of KMC, and the implementation of institution specific strategies to overcome these barriers (Wallin,et al., 2005 / Bergman &amp / Jurisco, 1994 / Cattaneo, et al., 1998). This study aims to determine the knowledge of and attitude towards kangaroo mother care, of nursing staff and kangaroo mothers in the Eastern sub-district of Cape Town.</p>
