How Much Do Formula-Fed Infants Take in the First 2 Days?

Objective. To document the intake of exclusively formula-fed newborns during the first 2 days of life. Methods. We enrolled a cohort of 50 healthy newborns ≥37 weeks’ gestation and documented their daily formula intake until discharge. We surveyed pediatricians regarding their assessment of the intake of formula fed infants. Results. In all, 37 of 50 newborns stayed for at least 48 hours. The mean ± SD gestational age was 39.5 ± 0.88 weeks. Mean ±SD formula intake for the first 48 hours (n = 37) was 57.2 ± 20.4 mL/kg/d and mean weight loss at 45.7 ± 8.8 hours, was 2.7% of birth weight. Pediatricians underestimated the amounts taken by these infants. Conclusions. In the first 2 days, healthy term newborns, fed formula ad lib, consume about 115 mL/kg, about 2 to 3 times as much as breastfed infants, and they lose only 2.7% of their birthweight by 48 hours. Most pediatricians underestimate the intake of formula-fed infants.

Objective: To evaluate vitamin D serum levels of term newborns and relate them to maternal concentrations and birth weight. Methods: Cross-sectional study carried out with 225 mothers and their term newborns. Data collected were maternal health, prenatal care, gestational, and anthropometric data of the newborns. The following laboratory tests were performed: serum levels of 25(OH)D, calcium, phosphorus, magnesium, and alkaline phosphatase. Results: Of the 225 newborns included in the study, 119 (52.9%) were males, the mean birth weight was 3,198 ± 421.4 g, and the gestational age was 39.1 ± 1.1 weeks. Of these, 20 (8.9%) were small and 12 (5.3%) were large for gestational age. A 25(OH)D sufficiency was found in 25.8% of mothers and 92% of newborns. The mean 25(OH)D concentrations of newborns was higher than that of the mothers 48.7 ± 15.2 ng/mL vs. 26.0 ± 6.7 ng/dL (p < 0.001), correlating inversely with birth weight (r = –0.249; p < 0.001). Small for gestational age (SGA) newborns had higher concentrations of 25(OH)D compared to adequate and large for age (p < 0.001). Conclusion: In conclusion, this study showed strong positive correlation between maternal and neonatal 25(OH)D concentrations, with higher values in newborns. The highest 25(OH)D concentrations were found in SGA term infants. We speculated these findings could be influenced by newborn body composition.

CONTEXT: Mid-arm circumference of the newborn is strongly associated with birth weight and is a very good indicator of low and insufficient birth weight. However, there are few Brazilian studies on the relationship between mid-arm and head circumferences and, thus, this does not form part of the routine evaluation for newborns. OBJECTIVES: To establish the mid-arm circumference and mid-arm/head circumference ratio in a population of term newborns. TYPE OF STUDY: Cross-sectional study carried out between June 1997 and August 1999. SETTING: Hospital Maternidade Leonor Mendes de Barros, São Paulo. PARTICIPANTS: Term newborns (66 males and 65 females) of appropriate growth for gestational age, whose mothers were healthy, were included in the study. MAIN MEASUREMENTS: Arm circumference, arm circumference/head circumference ratio, birth weight and gestational age were measured within 48 hours of birth. Data were considered significant when p < 0.01. RESULTS: The mean values for the mid-arm circumference were 10.76 cm (standard deviation, SD = 0.68) for females and 10.76 (SD = 0.81) for males. The mean value for the mid-arm/head circumference ratio was 0.31 (SD = 0.02) for both sexes. Mid-arm circumference values were significantly related to birth weight and gestational age, whereas mid-arm/head circumference ratio was related only to birth weight. CONCLUSIONS: Mid-arm circumference and mid-arm/head circumference ratio values were established for the studied population. It was possible to obtain curves for both mid-arm circumference and mid-arm/head circumference ratio in relation to birth weight. However, for mid-arm circumference, it was only possible to obtain curves in relation to gestational age. The use of the regression curves did not seem powerful enough to predict the mid-arm circumference and mid-arm/head circumference ratio in this population of term newborns. There were no gender differences for either of the measurements studied.

Severe Hyperbilirubinemia

Hyperbilirubinemia otherwise called ”jaundice” is yellowish-green pigmentation of the sclera and skin brought about by an expansion in bilirubin creation or an imperfection in bilirubin elimination. Prospective randomized comparative correlational study carried out on babies admitted to NICU in Krishna Hospital. All healthy term babies (= 37 weeks) with non haemolytic hyperbilirubinemia with absolute serum bilirubin =20 mg/dl - = 25 mg/dl from second day of life to fourteenth day of life. Out of 811 babies admitted in NICU during the study period, 52 babies were admitted for severe hyperbilirubinemia in NICU. Thus, the incidence rate was 6.4%.out of these 28 (53.84%) were male and 24 (46.15%) were female. The frequency of extreme hyperbilirubinemia was more in inborn babies (78.88%) than out born babies (21.15%). The frequency of extreme hyperbilirubinemia with respect to birth weight were, Weights between 2000 gms-3000gms were 40 (76.9%) and weight above 3000 gms were 12 (23.07%). The percentage weight loss from the time of birth till admission between enhanced and non enhanced gatherings was comparable. In the study, 28 (53.84%) were delivered per vaginally, 24 (46.15%) were born by LSCS. Most neonates in our study, 31 (59.61%) cases presented with in 2-5 days, 20 cases presented between 6-10 days and only one case between 11-14 days. The mean gestational age of presentation in both groups was not significant. By unpaired T test both supplemental and non supplemental groups are comparable i.e., the levels of bilirubin, rate of reduction of bilirubin between 2 groups is not significant. By ANOVA test i.e., the levels of bilirubin, rate of reduction of bilirubin in both the groups is highly significant. The complete length of phototherapy required between2 groups is not significant. This information show that organization of extra intravenous liquid in embittered sound, term, breastfed neonates have no useful impact on the pace of serum bilirubin decrease during phototherapy.

Type Sample

All breastfeeding infants lose some weight in the early days of life. Conventionally, 5% to 7% loss of birth weight has been accepted as the normal and expected amount of weight loss before infants begin to gain weight steadily. When infants lose more than 7% of their birth weight, breastfeeding adequacy is sometimes questioned and formula supplementation is often given. Despite the fact that 5% to 7% is well known and commonly cited, little reliable evidence exists that supports use of this figure as a guide to practice. A systematic review of studies that focused on infant weight loss was conducted. The main objective was to determine the mean amount of weight loss for healthy, full-term exclusively breastfed infants after birth. One previous review and 9 primary studies published since 2008 were examined. The reported mean infant weight loss ranged widely among studies from 3.79% to 8.6%. The point at which most infants have lost the most amount of weight occurs 2 to 4 days after birth. Close examination of the studies, however, revealed significant methodological flaws in the research. Study limitations commonly included gaps in data collection, lack of documented feeding type, sample groups that lacked adequate numbers of exclusively breastfed infants, and the exclusion of breastfed infants who lost the most weight. Well-designed clinical studies that address these limitations are needed.

Background: Preterm premature rupture of membranes (PPROM) is responsible for one?third of all preterm births worldwide. This aim of this study was to investigate the outcome of neonates born after prolonged PPROM with gestational age below 34 weeks. Materials and methods: This retrospective study included 65 patients who were born to mothers with Prolonged PPROM <34 weeks gestation between January 2011 and December 2015 and admitted to the neonatal intensive care unit (NICU) at Jordan University Hospital. Results: The mean gestational age of included patients was (31.9 ± 2.5 weeks), mean birth weight was (1840 ± 583 g) and 43 (66.2%) were males. The mortality rate in those infants was 12.3 %. Gestational age, birth weight, and Apgar score were significantly lower among mortality cases compared to surviving cases (P < 0.05). Conclusion: Prolonged PPROM before the 34th gestational week is associated with high rate of morbidity and mortality, for which early identification of risk factors for developing PPROM can help in reducing the risk for preterm labors and subsequent burden on healthcare system.

Maternal Race

Previous studies suggest that low birth weight black infants have less morbidity and birth-weight-specific mortality during the perinatal period than low birth weight white infants. We studied the effect of maternal race on outcome in preterm infants born at a military hospital that offers free access to obstetric and neonatal care. Between January 1, 1986, and December 31, 1991, data were prospectively collected on all 667 infants delivered at Wilford Hall USAF Medical Center with an estimated gestational age of less than 35 weeks. Three hundred ninety-two white infants and 165 black infants were included in the data analysis. The mean (±SD) birth weight was 1701 ± 65 g for white infants and 1462 ± 66 g for black infants. The mean estimated gestational age was 31.0 ± 3.2 weeks for white infants and 29.9 ± 3.8 weeks for black infants. Preeclampsia was more frequent in black mothers than in white mothers for the entire study population (21% vs 14%), but the birth weight differential between races remained after correction for preeclampsia. There were no significant differences between races in stillbirths, gender, maternal age, maternal transfer status, number of prenatal visits, or percentages of mothers with small-for-gestational-age infants, multiple-gestation infants, prolonged rupture of membranes, or initial prenatal visit during the first trimester. Intraventricular hemorrhage was more frequent in white infants at 27 through 29 weeks estimated gestational age (50% vs 13%). There were no significant differences between the two groups in survival or in the occurrence of severe infraventricular hemorrhage or bronchopulmonary dysplasia. It is concluded that preterm black infants are smaller than preterm white infants when matched for gestational age despite essentially equal utilization of prenatal care. However, maternal race has little direct effect on the survival of liveborn preterm infants in this population.

Abstract Background An increasing number of extremely preterm (EP) infants have survived worldwide. However, few data have been reported from China. This study was designed to investigate the short-term outcomes of EP infants at discharge in Guangdong province. Methods A total of 2051 EP infants discharged from 26 neonatal intensive care units during 2008–2017 were enrolled. The data from 2008 to 2012 were collected retrospectively, and from 2013 to 2017 were collected prospectively. Their hospitalization records were reviewed. Results During 2008–2017, the mean gestational age (GA) was 26.68 ± 1.00 weeks and the mean birth weight (BW) was 935 ± 179 g. The overall survival rate at discharge was 52.5%. There were 321 infants (15.7%) died despite active treatment, and 654 infants (31.9%) died after medical care withdrawal. The survival rates increased with advancing GA and BW (p < 0.001). The annual survival rate improved from 36.2% in 2008 to 59.3% in 2017 (p < 0.001). EP infants discharged from hospitals in Guangzhou and Shenzhen cities had a higher survival rate than in others (p < 0.001). The survival rate of EP infants discharged from general hospitals was lower than in specialist hospitals (p < 0.001). The major complications were neonatal respiratory distress syndrome, 88.0% (1804 of 2051), bronchopulmonary dysplasia, 32.3% (374 of 1158), retinopathy of prematurity (any grade), 45.1% (504 of 1117), necrotizing enterocolitis (any stage), 10.1% (160 of 1588), intraventricular hemorrhages (any grade), 37.4% (535 of 1431), and blood culture-positive nosocomial sepsis, 15.7% (250 of 1588). The multivariate logistic regression analysis indicated that improved survival of EP infants was associated with discharged from specialist hospitals, hospitals located in high-level economic development region, increasing gestational age, increasing birth weight, antenatal steroids use and a history of premature rupture of membranes. However, twins or multiple births, Apgar ≤7 at 5 min, cervical incompetence, and decision to withdraw care were associated with decreased survival. Conclusions Our study revealed the short-term outcomes of EP infants at discharge in China. The overall survival rate was lower than the developed countries, and medical care withdrawal was a serious problem. Nonetheless, improvements in care and outcomes have been made annually.

AbstractObjective:To compare different ultrasonographic fetal weight estimation formulas in predicting the fetal birth weight of preterm premature rupture of membrane (PPROM) fetuses.Methods:Based on the ultrasonographic measurements, the estimated fetal weight (EFW) was calculated according to the published formulas. The comparisons used estimated birth weight (EBW) and observed birth weight (OBW) to calculate the mean absolute percentage error [(EBW–OBW)/OBW×100], mean percentage error [(EBW–OBW)/OBW×100)] and their 95% confidence intervals.Results:There were 234 PPROM patients in the study period. The mean gestational age at which PPROM occured was 31.2±3.7 weeks and the mean gestational age of delivery was 32.4±3.2 weeks. The mean birth weight was 1892±610 g. The median absolute percentage error for 33 formulas was 11.7%. 87.9% and 21.2% of the formulas yielded inaccurate results when the cut-off values for median absolute percentage error were 10% and 15%, respectively. The Vintzileos’ formula was the only method which had less than or equal to 10% absolute percentage error in all age and weight groups.Conclusions:For PPROM patients, most of the formulas designed for sonographic fetal weight estimation had acceptable performance. The Vintzileos’ method was the only formula having less than 10% absolute percentage error in all gestational age and weight groups; therefore, it may be the preferred method in this cohort. Amniotic fluid index (AFI) before delivery had no impact on the performance of the formulas in terms of mean percentage errors.

Mature Weight

The mortality rates, weight changes and associated effects of a. draught in 1969 were observed in a herd of Shorthorn x Hereford (SH), Brahman x SH (BX) and Africander x SH (AX) crossbred cows and small herds of purebred Brahman and Africander cows at 'Belmont', Queensland. About half of the cows calved over a two month period from mid-October 1969. All the cows were weighed in February 1968, February and October 1969 and in January 1970 and the data from the crossbreds analysed by the method of least squares. The weights and weight changes of both the calving and non-calving groups followed a similar pattern though the weight changes of the non-calving group were of greater magnitude. The weights showed that the three crossbreds reached the same mature weight but at different rates. The SH cows reached mature weight least rapidly, had the highest mean weight loss during the drought and had the lowest mean gains after the season broke. Weight changes both during and after the drought were however dependent on lactational status in February 1969. The mean weight loss of cows that weaned a calf in 1969 (wet) was similar for all breeds. However, the mean loss of the dry SH cows was significantly greater than that of the dry BX and AX cows. Previously wet cows exhibited compensatory gains after calving but the gain of the wet SH cows was the lowest of the crossbred means. The mean birth weight of the SH calves was reduced below the long term mean by about 4 kg but birthweights of BX and AX calves were similar to those in other years. During the drought the purebred Brahmans lost the least and the purebred Africanders lost the most weight of all breeds. However, the nature of the data precludes any strict comparisons from being drawn. Mortality rates of breeding cows were recorded from 1960 to 1969. Rates were generally highest for the SH, particularly in the drought years of 1965 and 1969. Some reasons are advanced which may explain the differences in performance of the breed types.

Objectives This study aimed to determine leptin levels in term newborns who were born in the north of Jordan. We also aimed to investigate the relationships of leptin levels with fetal growth parameters, and to assess the difference in leptin levels according to sex and gestational age. Methods A cross-sectional descriptive study that involved 170 term newborns was conducted. A working sheet for data collection was created for each newborn and included sex, weight, length, head circumference, gestational age, and Apgar score. Blood samples were obtained from the umbilical cord vein of newborns after delivery to measure serum leptin levels. Data are shown as frequency, percentages, means, and standard deviations. Results We found that the mean leptin level was 1.17 ± 0.48 ng/mL. The independent t-test showed that the mean leptin level in boys (0.93 ± 0. 34 ng/mL) was significantly lower than that in girls (1.38 ± 0.47 ng/mL). Pearson’s correlations showed that leptin levels of newborns were positively and significantly correlated with weight, length, and head circumference. Conclusion In Jordanian healthy term newborns, leptin levels correlate with sex and intrauterine growth parameters.
