Full textINTRODUCTION: The association between intrauterine growth restriction (IUGR) and renal alterations refers to issues such as the relation between reduced renal vascularization in these fetuses and the fetal hemodynamics during pregnancy, which were not sufficiently investigated so far. Considering that the primary cause of nefrons reduction in these fetuses would be the renal hypoflow caused by the redistribution of the fetal hemodynamics resulting from hypoxic stimuli, it would be expected that the severety of the fetal impairment could result in worse renal vascularization in IUGR fetuses. OBJECTIVES: This study aimed at evaluating IUGR fetuses in order to (1) describe the pulsatility index of renal arteries, the renal volume and the renal vascularization indexes, as well as (2) verify correlations of the doppler findings in the umbilical arteries, middle cerebral artery, and venous duct with the pulsatility index of the renal arteries, the renal volume, and the renal vascularization indexes (VI, FI, VFI), and of the pulsatility index of the renal arteries, the renal volume, and the renal vascularization indexes with the amniotic liquid index. METHODS: 81 fetuses with IUGR were assessed with tridimentional power doppler in order to determine data regarding the pulsatility index of the renal arteries, the renal volume, the renal vascularization indexes, the pulsatility indexes of umbilical arteries, middle cerebral artery and venous duct, and the amniotic liquid index. Data were undertaken to statistical analysis for establishing eventual correlations among such assessed parameters. RESULTS: Pulsatility index of renal arteries ranged from 1.50 to 3.44 (median of 2.39 + 0.41); renal volume ranged from 1.90 to 18.90 (median of 8.54 + 3.43); renal VI ranged from 0.05 to 7.75 (median of 1.57 + 1.58); renal FI ranged from 19.04 to 40.0 (median of 28.29 + 5.06); and renal VFI ranged from 0.03 to 5.18 (median of 0.96 + 1.3. There was no correlation between the pulsatility index of renal arteries and the pulsatility indexes of the umbilical arteries, middle cerebral artery, and venous duct; correlations were not observed as well between the renal volume and the pulsatility indexes of the umbilical arteries, middle cerebral artery, and venous duct. Renal VI and VFI correlated negatively with the pulsatility index of the venous duct, and positively with the amniotic liquid index. There was no correlation betweem renal vascularization indexes and doppler findings in umbilical arteries and in middle cerebral artery, neither between pulsatility index of renal arteries, renal volume and renal FI and the amniotic liquid index. CONCLUSION: The pulsatility index of the venous duct was better predictive of alterations in renal vascularization index, suggesting that such alterations are more evident in IUGR fetuses with more severe hemodynamic impairments

Full textThe objective of this study was to compare neonatal morbidity and mortality between late-preterm infants (gestational age at birth: 34 to 36 weeks and 6 days) with and without fetal growth restriction (FGR). A longitudinal study was conducted between October 2004 and October 2006 involving 50 pregnant women with pre-term delivery associated with FGR (group I) and 36 women with spontaneous preterm delivery not associated with FGR (group II). The following postnatal outcomes were evaluated: weight and gestational age at birth, cesarean section rate, 5-minute Apgar score, umbilical artery pH at birth, and need for and duration of orotracheal intubation and hospitalization in the neonatal intensive care unit (NICU), as well as the presence of respiratory distress syndrome (RDS), sepsis, thrombocytopenia, hypoglycemia, intracranial hemorrhage (ICH) and jaundice, need for phototherapy, length of hospital stay, and occurrence of death. The chi-square test, Fishers exact test and nonparametric Kruskal-Wallis test were used for statistical analysis, adopting a level of significance of 5%. Gestational age was similar in groups I and II, with a mean of 35.5 weeks in both groups. A higher frequency of the following adverse postnatal outcomes was observed in group I: lower birth weight (p<0.001), higher incidence of cesarean section (92% versus 25% in group II; p<0.0001), greater need for NICU treatment (58% versus 33%; p=0.041), longer hospital (p<0.001) and NICU stay (p<0.001), higher frequency of ICH (12% versus 0; p=0.037) and hypoglycemia (24% versus 6%; p=0.047), and longer duration of phototherapy (p=0.005). No differences in Apgar scores, cord pH, orotracheal intubation, RDS, thrombocytopenia, sepsis, or jaundice were observed between groups. There were no cases of hyaline membrane disease, bronchopulmonary dysplasia, pulmonary hemorrhage, or neonatal death. In conclusion, the group of late-preterm infants with FGR presented more neonatal complications than the group without FGR

Full textThe aim of this study was to correlate uterine height measurements below the 5th and 10th percentiles using MARTINELLI et al. (2001) curve to fetal growth restriction (FGR) and to compare with the BELIZÁN et al. (1978) curve. During the period of July 2000 and February 2003, 238 pregnant women of high risk were submitted to uterine height measurements between the 20th and 42nd weeks of gestation. The whole group had well-known gestational age, confirmed by early ultrasound. The diagnosis of FGR was confirmed after birth according to RAMOS (1983). Among these women, 50 (21,0%) gave birth to light for gestational age infants. The same observer, using tape measure, performed 1617 uterine height measurements, from the upper border of the symphysis pubis to the fundus uteri. For the diagnosis of FGR, being considered as positive the exam with measurements below the 10th percentile according to MARTINELLI et al. (2001) curve, the sensitivity (SE), specificity (SP), positive predictive value (PPV) and negative predictive value (NPV) were 78,0%, 77,1%, 47,6% and 92,9%, respectively. For the 5th percentile, this curve showed SE= 64,0%, SP= 89,9%, PPV= 62,7% and NPV= 90,4% for the detection of FGR. The BELIZÁN et al. (1978) curve, having the 10th percentile as the limit, yielded SE= 54,0%, SP= 97,3%, PPV= 84,4% and NPV= 88,8% for the identification of FGR. We conclude that, when used for screening FGR, the MARTINELLI et al. (2001) curve showed greater sensitivity and negative predictive value, and presents better results than that of Belizán et al. (1978)

Full textIntroduction: intrauterine growth restriction (IUGR) is an obstetric intercurrence of relevant prevalence and high morbidity and mortality rates. Obstetrical ultrasonography is still limited to diagnose brain impairment in IUGR. Therefore, in order to increase the diagnostic accuracy of brain lesions and impairment of the affected child, some studies using magnetic resonance imaging (MRI) have emerged, but with technical difficulties. Hence, studies that evaluate the brain of fetuses with IUGR and that identify simple biomarkers of chronic and/or acute hypoxia are needed. Objectives: to compare morphometric parameters measured by MRI of the skull and brain of fetuses with normal growth and fetuses with IUGR. Methods: this was a prospective cohort study that included 13 fetuses with normal growth and 13 fetuses with IUGR from singleton pregnancies, in the ratio 1 case: 1 control, from 26 to 38 weeks of gestational age (GI) who underwent ultrasound evaluation to determine the biometry, amniotic fluid volume and fetal Doppler velocimetry and MRI for evaluation of brain and cranial measurements. Variables related to the type of delivery, birth conditions and adverse perinatal outcomes were obtained from medical records. Wilcoxon and Chi-square tests were used for statistical analysis. Results: the measurements of skull and brain biparietal diameter (BPD) and skull occipitofrontal diameter (OFD) of IUGR fetuses were lower than those of controls, as well as the percentiles of these diameters, head circumference and the brain OFD. It has also been observed that the median of the brain BPD/cerebellar diameter ratio of the IUGR fetuses tended to be lower than that of the controls. In addition, measurements of the extracerebral cerebrospinal fluid (CSF) and their percentiles were also lower in IUGR fetuses. There are also differences in the skull OFD/ CSF, brain OFD/ CSF, skull BPD/ CSF and brain BPD/ CSF and extracerebral CSF ratios between the groups of fetuses studied. In addition, measurements of right and left axial interopercular distances were significantly lower in the IUGR fetuses. Conclusions: we can conclude that IUGR fetuses have smaller cranial and brain measures than fetuses with normal growth, besides having reduction of extracerebral CSF. Fetal MRI studies with larger number of subjects, allowing analysis with multivariate logistic regression and those which assess neurological impairment of affected children are needed.

Full textObjective: To examine the association between isolated single umbilical artery (ISUA) and fetal growth restricion. Methods: Case control study with retrospective review of 131 singleton pregnancies with isolated single umbilical artery diagnosed prenataly between 1998 and 2010. Control group consisted of 730 singleton pregnancies prospectively evaluated with histological confirmation of 3 vessels cord. Mean birthweight and frequency of low birthweight ( < 2,500g), very low birthweigh ( < 1,500g) and fetal growth restriction below the 5th and 10th centiles were compared between groups. Odds ratios and 95% confidence intervals were calculated for significant differences. Logistic regression analysis was used to examine the association between fetal growth restriction and significant independent variables. Results: The mean birthweight difference between ISUA (n=131, 2,840+-701g) and control (n=730, 2,983+-671g) pregnancies was 143g (95%CI= 17-269; p= 0.04). Birthweight below the 5th centile was more common in ISUA (21.4% versus 13.6%, p= 0.02, LR= 1.57, 95%CI: 1.07- 2.25); particularly in the subgroup of pregnancies with associated maternal disease or pregnancy complication (28.6% versus 14.1%, p= 0.02, LR= 2.22, 95%CI: 1.12-4.25). No significant differences were observed in low birthweight, very low birthweight or birthweight below the 10th centile. Logistic regression analysis demonstrated that birthweight below the 5th centile was significantly associated with ISUA only. Conclusion: Isolated single umbilical artery is associated with 1.6 times increased risk of birthweight below the 5th centile. In pregnancies with associated maternal disease or pregnancy complication, this risk is increased 2.2 times

Objectives: to evaluate the validity of transverse cerebellar diameter (TCD)/abdominal circumference (AC) ratio as an ultrasonographic diagnosis method of fetal growth restriction (FGR). To calculate by receiver operator characteristic (ROC) curve the best cut-off value of TCD/AC ratio. To verify whether TCD/AC has its accuracy modified according to the dependence of type of FGR (symmetric and asymmetric) or according to the time between ultrasonography and deliverance. To compare TCD/AC ratio at its cut-off with the femur length (FL)/ abdominal circumference (AC) ratio. Method: a prospective cross-sectional study, carried out in 250 pregnant women with singleton pregnancies between 20 and 42 weeks of gestation, known accurate gestational age with ultrasound confirmation, living fetuses. Obstetrics sonographic examinations were accomplished until gestation resolution, but only the last one, within 14 days of the deliverance, was used for analysis. Neonates with TCD/AC ratio greater than the cut-off, established by ROC curve were diagnosed as FGR. The same was considered for FL/AC ratio. We classified as gold standard for FGR in new-born infants, who presented birth weight bellow 10th percentile of gestational age according to the growth curves of Lubchenco et al. (1963), corrected according to their sex. Neonates showing FGR and Rohrer ponderal index between 2,2 and 3,0 were labeled as symmetric FGR. Those showing FGR and ponderal index below 2,2 were labeled as asymmetric FGR. Results: prevalence of FGR among the study group was 12,4%. The best cut-off value calculated by ROC curve for TCD/AC ratio was 16,15. The sensitivity, specificity, accuracy, positive predictive values and negative predictive values, likelihood ratio for positive and negative tests were 77,4%, 82,6%, 38,7%, 96,3%, 82%, 4,5 and 3,7, respectively. In the symmetric FGR, sensitivity and specificity were 80,8% and 81,7%, respectively. In the asymmetric FGR, sensitivity and specificity were 60% and 75%, respectively. Results lower than in the symmetric FGR, but not statistically significant (p > 0,05). In the interval zero to seven days between sonographic examination and deliverance, sensitivity and specificity were 81,5% and 82,1%, respectively. In the interval of eight to 14 days, sensitivity and specificity were 50% and 84,3%, respectively, with no statistically significant difference (p > 0,05). The best cut-off value calculated by ROC curve for FL/AC ratio was 22,65, showing sensitivity, specificity, accuracy, positive predictive values and negative predictive values, likelihood ratio for positive and negative tests of 67,7%, 81,7%, 34,4%, 94,7%, 80%, 3,7 and 2,5, respectively. Conclusions: TCD/AC ratio at cut-off 16,15 proved to be an effective method in antenatal diagnosis of FGR, both symmetric as asymmetric, with no influence of interval between ultrasonography examination and deliverance. As a gestational age-independent method, it is useful enough in the occurrence of cases where these data are unknown. FL/AC ratio proved is not so effective as TCD/AC ratio in diagnosis of FGR.
Objetivos: testar a validade da relação diâmetro transverso do cerebelo (DTC) /circunferência abdominal (CA) como método diagnóstico ultra-sonográfico da restrição de crescimento fetal (RCF). Determinar, através de curva ROC (receiver operator characteristic), o melhor ponto de corte da relação DTC/CA. Verificar se a relação DTC/CA tem sua acurácia modificada na dependência do tipo de RCF (simétrica ou assimétrica) ou do tempo entre a ultra-sonografia e o parto. Comparar DTC/CA, no ponto de corte obtido, com a relação comprimento do fêmur (CF) /circunferência abdominal (CA). Método: estudo prospectivo, seccional, envolvendo 250 gestantes com gravidez única, idade gestacional precisa, feto vivo. Foram realizadas ultra-sonografias obstétricas até a resolução da gestação, mas somente a última foi considerada para análise. Os neonatos cujas relações DTC/CA estiveram maiores do que o ponto de corte determinado pela curva ROC foram considerados acometidos por RCF. Idem para a relação CF/CA. Considerou-se como padrão-ouro para o diagnóstico de RCF os recém-nascidos cujos pesos situaram-se abaixo do percentil 10 para a idade gestacional nas curvas de Lubchenco et al. (1963), corrigidas para sexo. Definiu-se RCF simétrica neonatos com índice ponderal de Rohrer situado entre 2,2 e 3.0. Aqueles com RCF cujos índices fossem < 2,2 foram classificados como RCF assimétrica. Resultados: a prevalência da RCF foi de 12,4%. O ponto de corte da relação DTC/CA determinado pela curva ROC foi 16,15. A sensibilidade, especificidade, valores preditivos positivo e negativo, acurácia, razões de verossimilhança positiva e negativa foram de 77,4%, 82,6%, 38,7%, 96,3%, 82%, 4,5 e 3,7, respectivamente. Na RCF simétrica a sensibilidade e especificidade foram de 80,8% e 81,7%, respectivamente. Na assimétrica a sensibilidade e especificidade foram 60% e 75%, respectivamente. Resultados menores do que na simétrica, porém, não estatisticamente significantes (p > 0,05). No intervalo de zero a sete dias entre a última ultra-sonografia e o parto, a sensibilidade e especificidade foram de 81,5% e 82,1%, respectivamente. No intervalo de oito a 14 dias, a sensibilidade e especificidade foram de 50% e 84,3%, respectivamente, sem diferença estatisticamente significante entre os dois intervalos (p > 0,05). O ponto de corte da relação CF/CA foi de 22,65, com sensibilidade, especificidade, valores preditivos positivo e negativo, acurácia, razões de verossimilhança positiva e negativa de 67,7%, 81,7%, 34,4%, 94,7%, 80%, 3,7 e 2,5, respectivamente. Conclusões: a relação DTC/CA no ponto de corte 16,15 mostrou-se método eficaz no diagnóstico de RCF, tanto simétrica quanto assimétrica, não sendo influenciada pelo tempo entre a última ultra-sonografia e o parto. Sendo método independente da idade gestacional, é especialmente útil nos casos em que este dado é ignorado. A relação CF/CA mostrou-se menos eficaz do que a DTC/CA no diagnóstico da RCF.

Resumo: A restrição do crescimento intrauterino (RCIU) limita o desenvolvimento fetal adequado aumentando a morbidade e mortalidades perinatais. Os mecanismos fetais adaptativos na RCIU podem desencadear alterações endócrinas e metabólicas que explicariam a ocorrência de doenças na idade adulta. O objetivo do estudo foi avaliar na RCIU experimental pela ligadura da artéria uterina se existem alterações na morfometria e histologia do fígado, intesti no e rins e se existem diferenças na expressão dos receptores de insulina, IR-(3, IRS-1, IRS-2, IGF-IR(3 no grupo de fetos submetidos à RCIU. O presente experimento foi submetido ao Comitê de Ética e Experimentação Animal da Universidade Estadual de Campinas (CEEA-UNICAMP) e aprovado como projeto de pesquisa N° 1644-1. Para realização do estudo utilizamos fetos de ratas Sprague Dawley divididos em 3 grupos. Grupo I (RCIU) - 40 fetos submetidos à ligadura da artéria uterina unilateral com 18,5 dias de gestação, Grupo II (Controle-RCIU) - 40 fetos do corno oposto ao da ligadura da artéria uterina e Grupo III (Controle Externo) - 40 fetos sem procedimento cirúrgico ou alimentar. Os resultados mostraram no modelo experimental de RCIU uma diminuição do peso corporal (PC), hepático (PH) e intestinal (PI) (p<0,01) no grupo RCIU, as relações entre PH/PC, PI/PC, PR/PC foram mantidas, fetos RC IU tem diminuição das camadas submucosas e mucosas intestinais (p<0,05); diminuição da camada cortical renal e do número de glomérulos, com aumento do volume glomerular (p<0,05). Na RCIU encontramos menor expressão hepática do IR-(3, IRS-1 e IRS-2, menor expressão do IRS-2 no intestino e rins e maior expressão do IGF-IR(3 em todos os tecidos. O modelo experimental estudado causou uma RCIU simétrica com alterações morfométricas e do metabolismo da glicose que poderiam justificar no futuro um maior risco de doenças metabólicas
Abstract: Intrauterine growth restriction (IUGR) limits appropriate fetal development increasing morbidity and perinatal mortality. Adaptive mechanisms in fetal IUGR may leave to endocrine and metabolic alterations that could explain the occurrence of diseases in adulthood. The aim of this study was to evaluate whether experimental IUGR by uterine artery ligation causes changes in morphology and histology of the liver, intestines and kidneys. We also evaluated if there were differences in the expression of insulin receptors, IR-(3, IRS-1, IRS-2, IGF-IR(3 of fetuses subjected to IUGR. This experiment was submitted to the Ethics and Animal Experimentation of the Campinas State University (UNICAMP CEEA) and was approved as a research project No. 1644-1. The study used fetuses Sprague-Dawley rats divided into 3 groups. Group I (IUGR) - 40 fetuses who underwent uterine artery ligation sided with 18.5 days of pregnancy Group II (Control-IUGR) - 40 fetuses of the horn opposite to the uterine artery ligation, and Group III (External Control) - 40 fetuses without surgery or food The results showed the experimental model of IUGR, a reduction in body weight (BW), liver (PH) and intestine (PI) (p <0.01) in IUGR, the relationship between PH/PC, PI/PC, PR/PC have been retai ned, IUGR fetuses have reduced layers of the intestinal mucosa and submucosa (p<0,05), decreased renal cortical layer and the glomerular number and increased volume rate (p<0,05). In IUGR found lower hepatic expression of IR-(3, IRS-1 and IRS-2, reduced expression of IRS-2 in the intestine and kidney and increased expression of IGF-IR(3 in all tissues. The experimental model studied caused a symmetrical IUGR with histological changes and glucose metabolism that could justify a greater risk of metabolic diseasesin the future

Full textEvaluation of depression, stress, social support and self-esteem in pregnant woman with suspected fetal growth restriction [Dissertation]. São Paulo: Faculdade de Medicina, Universidade de São Paulo; 2017. Introduction: Fetal Growth Restriction (FGR) is the condition in which fetal weight is below the 10th percentile for gestational age. This condition characterizes a high-risk pregnancy and is an important cause of perinatal morbidity and mortality. In addition to biological fetal, maternal and placental factors, the FGR is influenced by psychosocial factors such as depression and stress. This study aims to compare pregnant woman with suspected FGR and pregnant woman without clinical intercurrences in relation to depression, stress, social support and self-esteem. Methods: Cross-sectional study with 79 pregnant women with suspected FGR, met at the Low Fetal Weight Clinic of the PRIME-MD was used to evaluate depression and PPP for stress assessment, social support and self-esteem. Quantitative analysis was performed using the t-test or non-parametric Mann-Whitney test and for comparison of more than two groups was considered the nonparametric Kruskal-Wallis test. The Dunn test, with corrected p values, was used for 2 on 2 comparisons. The Pearson\'s chi-square tests or Fisher\'s exact tests were used for qualitative data analysis. Results: In the present study, pregnant women with a suspicion of FGR had a mean age of 25.89 (SD=6.11), mean gestational age of 33.33 weeks (SD=3.36 weeks) and average gestation numbers of 1.92 (SD=1.22). The pregnant woman without clinical intercurrences presented averages 27,27 (SD=5.90), 32.55 (SD=4.01) and 1.83 (SD=0.93), respectively. A diagnosis of depression was found among 17.7% of pregnant women with suspected FGR and 16.3% of pregnant women without clinical intercurrences. As for stress, peer support, support from other people and self-esteem was found among pregnant women with suspected FGR mean scores of 18.27 (SD=5.50), 55.15 (SD=13.76), 53.77 (SD=13.27) and 32.70 (SD=4.60). Among the pregnant women without clinical intercurrences, the mean scores were 19.72 (SD=5.16), 55.70 (SD=11.37), 51.33 (SD = 13.26) and 34.22 (SD = 4.85), respectively. The statistical significance of stress (p < 0.01) and self-esteem (p < 0.01) were found in the association between the groups with suspected FGR and depression (RCF+D) and with suspected FGR without depression (RCF-D). Among the groups without intercurrences and with depression (BR+D) and without intercurrences and without depression (BR-D), statistical significance was observed between stress (p=0.04) and self-esteem (p < 0.01). Among the RCF+D and BR-D groups, statistical significance was found between self-esteem (p < 0.01). Among the BR + D and RCF-D groups, statistical significance was found between self-esteem (p=0.03). Statistical differences were not found for stress among the RCF+D and BR+D, RCF-D and BR-D, and BR-D and RCF+D groups, and for self-esteem between the RCF+D and BR+D groups, And RCF-D and BR-D. None of the groups studied presented statistical difference regarding the support scores of the companion and the support of other people. Conclusions: In this study, the presence of depression during pregnancy was associated with a higher stress score and lower self-esteem score both among pregnant women with FGR suspicion and among pregnant women without clinical intercurrences

Full textIntroduction: Fetal environment changes can lead to adaptations that are associated with increased risk for obesity, cardiovascular disease, hypertension and diabetes in adult life. Evidence suggests that intrauterine growth restriction (IUGR) can persistently program the subject’s preference for palatable foods. It is believed that feeding behavior alterations can explain, at least in part, the increased risk for chronic diseases in IUGR individuals. Therefore, it becomes important to understand the factors and mechanisms involved in this behavior. The aim of this study was to explore how IUGR affects feeding behavior of animals and humans, as well as to verify the potential mechanisms related to this behavioral programming. Methods: Time-mated pregnant Sprague-Dawley rats were randomly allocated to Control (receiving standard chow ad libitum) or 50% food restricted (FR), receiving 50% of the ad libitum-fed dam’s habitual intake. These diets were provided from day 10 of pregnancy throughout day 21 of lactation. Within 24 hours after birth, pups were crossfostered, forming four groups: Adlib_Adlib, FR_Adlib, FR_FR, Adlib_FR. Standard chow consumption was compared between all groups. Food preference, conditioned place preference to a palatable diet, and the nucleus accumbens tyrosine hydroxylase phosphorylation and D2 receptor levels were analyzed focusing on two groups of interest (Adlib_Adlib and FR_Adlib). In humans, 75 youths were classified regarding IUGR and had anthropometric data, biochemical data, and feeding behavior (food choice task, in which everyone received a monetary value to purchase a snack, and Dutch Eating Behaviour Questionnaire) assessed. Forty three neuroimaging exams were performed and resting state functional connectivity between brain regions related to reward of 28 individuals were processed and analyzed. Results: In the experimental study, standard chow consumption was not different between groups. IUGR adult rats had increased preference for palatable food, but showed less conditioned place preference to a palatable diet compared to controls. At baseline, the accumbal tyrosine hydroxylase phosphorylation was increased in IUGR rats compared to controls. After sweet food exposure, the difference between groups remained only in males. Accumbal D2 receptors levels were decreased in IUGR rats. In the clinical study, it was found that low birth weight ratio (indicative of higher IUGR) and high body mass index predict a restrained eating style as seen by the DEBQ. IUGR individuals used a smaller quantity of a financial resource offered in the food choice task after a fasting period. Resting state functional connectivity data suggest that IUGR individuals had an altered pattern of connectivity between the orbitofrontal cortex, the ventral/dorsal striatum and the amygdala. Conclusion: IUGR was associated with a preference for palatable foods and alterations in the dopaminergic system in the experimental study, as well as changes in the resting state functional connectivity between regions of the mesocorticolimbic pathway in the clinical study. Alterations in the mesolimbic dopaminergic system observed in IUGR rats indicate an important role in the programming of food preferences. Moreover, the IUGR pattern of brain connectivity observed suggests that alterations in certain regions involved in reward processing and evaluation could be associated with changes in eating behavior. Neurobehavioral changes observed confirmed the existence of a fetal programming of feeding behavior associated with IUGR, pointing out to persistent modifications in the brain reward system, which can be seen as a risk factor for the development of obesity and its comorbidities.
