Amino acid composition of parturient plasma, the intervillous space of the placenta and the umbilical vein of term newborn infants BJMBR
Camelo Jr.,J.S.; Jorge,S.M.; Martinez,F.E..
The objective of the present study was to determine the levels of amino acids in maternal plasma, placental intervillous space and fetal umbilical vein in order to identify the similarities and differences in amino acid levels in these compartments of 15 term newborns from normal pregnancies and deliveries. All amino acids, except tryptophan, were present in at least 186% higher concentrations in the intervillous space than in maternal venous blood, with the difference being statistically significant. This result contradicted the initial hypothesis of the study that the plasma amino acid levels in the placental intervillous space should be similar to those of maternal plasma. When the maternal venous compartment was compared with the umbilical vein, we...

Application of continuous positive airway pressure in the delivery room: a multicenter randomized clinical trial BJMBR
Gonçalves-Ferri,W.A.; Martinez,F.E.; Caldas,J.P.S.; Marba,S.T.M.; Fekete,S.; Rugolo,L.; Tanuri,C.; Leone,C.; Sancho,G.A.; Almeida,M.F.B.; Guinsburg,R..
This study evaluated whether the use of continuous positive airway pressure (CPAP) in the delivery room alters the need for mechanical ventilation and surfactant during the first 5 days of life and modifies the incidence of respiratory morbidity and mortality during the hospital stay. The study was a multicenter randomized clinical trial conducted in five public university hospitals in Brazil, from June 2008 to December 2009. Participants were 197 infants with birth weight of 1000-1500 g and without major birth defects. They were treated according to the guidelines of the American Academy of Pediatrics (APP). Infants not intubated or extubated less than 15 min after birth were randomized for two treatments, routine or CPAP, and were followed until hospital...

Association between type of feeding at discharge from the hospital and nutritional status of very low birth weight preterm infants BJMBR
Martins-Celini,F.P.; Gonçalves-Ferri,W.A.; Aragon,D.C.; Bernichi,J.P.; Calixto,C.; Sacramento,E.M.F.; Santos,M.A.; Martinez,F.E..
The ideal feeding for premature babies has been the source of extensive debate. The aim of this study was to assess the association between type of feeding at discharge and the nutritional status of very low birth weight infants. This was a retrospective cohort of preterm babies with birth weight ≤1500 g, born between January 2006 and December 2013. The infants were divided into 3 groups according to type of feeding at discharge: exclusive breast milk (group 1), mixed feeding (group 2) and exclusive artificial formula (group 3). Frequencies of each group were calculated, as well as mean Z-score differences in weight, length and head circumference. Six hundred and forty-nine newborns were included. The mean weight of groups 1, 2, and 3 was 1338.7, 1104.0,...

Examining the side effects of sucrose for pain relief in preterm infants: a case-control study BJMBR
Linhares,M.B.M.; Gaspardo,C.M.; Souza,L.O.; Valeri,B.O.; Martinez,F.E..
Sucrose solution is recommended as relevant pain relief management in neonates during acute painful procedures; however, only a few studies have analyzed the potentially adverse effects of sucrose administration to preterm neonates. The goal of this study was to examine the potential side effects of sucrose for pain relief in preterm infants, assessing feeding and weight gain during hospitalization and their feeding patterns postdischarge. The study sample consisted of 43 preterm neonates divided into two groups: a sucrose group (SG, n=18) and a control group (CG, n=25) in which no sucrose was administered. The SG received 0.5 mL/kg 25% oral sucrose for 2 min prior to all acute painful procedures during three consecutive days. A prospective review of...

Long-term melatonin treatment reduces ovarian mass and enhances tissue antioxidant defenses during ovulation in the rat BJMBR
Chuffa,L.G.A.; Amorim,J.P.A.; Teixeira,G.R.; Mendes,L.O.; Fioruci,B.A.; Pinheiro,P.F.F.; Seiva,F.R.F.; Novelli,E.L.B.; Mello Júnior,W.; Martinez,M.; Martinez,F.E..
Melatonin regulates the reproductive cycle, energy metabolism and may also act as a potential antioxidant indoleamine. The present study was undertaken to investigate whether long-term melatonin treatment can induce reproductive alterations and if it can protect ovarian tissue against lipid peroxidation during ovulation. Twenty-four adult female Wistar rats, 60 days old (± 250-260 g), were randomly divided into two equal groups. The control group received 0.3 mL 0.9% NaCl + 0.04 mL 95% ethanol as vehicle, and the melatonin-treated group received vehicle + melatonin (100 µg·100 g body weight-1·day-1) both intraperitoneally daily for 60 days. All animals were killed by decapitation during the morning estrus at 4:00 am. Body weight gain and body mass index...

Nasal CPAP in the delivery room for newborns with extremely low birth weight in a hospital in a developing country BJMBR
Gonçalves-Ferri,W.A.; Martinez,F.E..
The objective of this study was to determine the feasibility of the use of continuous positive airway pressure installed prophylactically in the delivery room (DR-CPAP), for infants with a birth weight between 500 and 1000 g in settings with limited resources. During 23 months, infants with a birth weight between 500 and 1000 g consecutively received DR-CPAP. A total of 33 infants with low birth weight were enrolled, 16 (48.5%) were females. Only 14 (42.4%) received antenatal corticosteroids and only 2 of those 14 (14.3%) infants weighing 500-750 g were not intubated in the delivery room, and apnea was given as the reason for intubation of these patients. Of the 19 infants in the 751-1000 g weight range, 9 (47.4%) were intubated in the delivery room, 6 due...

Pediatric pain: prevalence, assessment, and management in a teaching hospital BJMBR
Linhares,M.B.M.; Doca,F.N.P.; Martinez,F.E.; Carlotti,A.P.P.; Cassiano,R.G.M.; Pfeifer,L.I.; Funayama,C.A.; Rossi,L.R.G.; Finley,G.A..
The goal of this study was to examine the prevalence, assessment and management of pediatric pain in a public teaching hospital. The study sample consisted of 121 inpatients (70 infants, 36 children, and 15 adolescents), their families, 40 physicians, and 43 nurses. All participants were interviewed except infants and children who could not communicate due to their clinical status. The interview included open-ended questions concerning the inpatients’ pain symptoms during the 24 h preceding data collection, as well as pain assessment and pharmacological/non-pharmacological management of pain. The data were obtained from 100% of the eligible inpatients. Thirty-four children/adolescents (28%) answered the questionnaire and for the other 72% (unable to...

Plasma amino acids in pregnancy, placental intervillous space and preterm newborn infants BJMBR
Camelo Jr.,J.S.; Martinez,F.E.; Gonçalves,A.L.; Monteiro,J.P.; Jorge,S.M..
Plasma amino acid levels have never been studied in the placental intervillous space of preterm gestations. Our objective was to determine the possible relationship between plasma amino acids of maternal venous blood (M), of the placental intervillous space (PIVS) and of the umbilical vein (UV) of preterm newborn infants. Plasma amino acid levels were analyzed by ion-exchange chromatography in M from 14 parturients and in the PIVS and UV of their preterm newborn infants. Mean gestational age was 34 ± 2 weeks, weight = 1827 ± 510 g, and all newborns were considered adequate for gestational age. The mean Apgar score was 8 and 9 at the first and fifth minutes. Plasma amino acid values were significantly lower in M than in PIVS (166%), except for aminobutyric...
