“…Regarding the method of assessing weight change, some authors performed daily weights , others only performed daily weights up to discharge or until newborn infants regained their birthweight . Manganaro et al.…”

“…In the aforementioned studies, newborn weight change was described as the amount and, or, timing and the diversity of descriptions made it even harder to compare study results. Weight change has been previously described as the amount in grams or kilograms lost or gained , as the percentage of birthweight lost or gained , or simply as the day when the newborn infants started to gain weight or when they regained their birthweight . In addition, some authors presented the results as mean weight change , median weight change , range of weight change , number of subjects over or under some predetermined percentage of weight loss or percentile data .…”

“…In our study, although the preterms were analyzed, we found that our rates were more positive because of the large differences in the general clinical situation between the preterms and the weight loss interval. Hossain et al reported that 56% of newborns started to regain weight within the first 5 days in their studies involving low birth weight newborns [14]. Jolly et al reported that 90% started to regain weight within the first 3 days [15].…”

Aim: Survival and complications are very sensitive in preterm infants. Any negative situation in the preterms can lead to unintended consequences. In this study, it was aimed to analyze the data on demographic characteristics, complications, morbidity, mortality, and weight monitoring information of a high number of preterm neonates. Material and Methods: A total of 1091 preterm newborns born before the 37th gestational week in our tertiary care hospital were included in the study. All data were analyzed from hospital records. The weights of the newborns at birth, on the 7th, 15th, and 30th days were recorded.. Results: Of the newborns, 39 (3.6%) died within 30 days after delivery. The cesarean section rate was 91.7%. While 7.9% of the preterms had birth weight below 1000 grams, the preterm rate in normal birth weight (>2500 g) was 15.6%. The mean birth weight was 1909.76 g, the first day mean weight loss was 0.6%, the first 3-day mean weight loss was 3.8% and the first 7-day mean weight loss was 2.5%. The mean birth weight in late preterm infants was significantly lower than in those who were born in the following weeks, while the mean birth weight in late preterm births was significantly higher than in those born before (p<0.001). Discussion: We found that preterm infants and those with lower birth weight had a worse prognosis, and that weight gain after birth was associated with prognosis. We believe that data obtained from our study may be a guide for clinicians and researchers.

“…Indeed, transitioning from in utero (fetus) to ex utero (infant) is a complex metabolic process that varies as a function of both PMA and postnatal age. Hossain et al 25 showed that weight loss in term babies is shorter (5 days) than in preterm babies (10 to 14 days); indeed, PMA was important even in the near-term and term ( 34 weeks' gestation) populations of infants. 26 It seems that in postnatal day 2 of life, weight loss is more marked in breast-fed infants than in formula-fed babies.…”

Infant exposure to ethylmercury (EtHg) has not only increased but is starting earlier as a result of the current immunization schedule that uses thimerosal-containing vaccines (TCVs). Although vaccination schedule varies considerably between countries, infants in less-developed countries continue to be exposed to EtHg derived from more affordable TCVs. We studied the exposure of newborns to EtHg from hepatitis B vaccines; hospital records (21,685) were summarized for the years 2001 to 2005 regarding date of birth, vaccination date, and birth weight. Most of the vaccinations occurred in the first 24 hours postdelivery; over the 5 years, there was an increase in vaccinations within hours of birth (same day), from 7.4% (2001) to 87.8% (2005). Nearly 94.6% of infants are now being vaccinated within the first 24 hours. Range of mercury exposure spread from 4.2 to 21.1 microg mercury/kg body weight for those receiving TCVs with the highest thimerosal concentration; these exposure levels are conservative for 2% of children receiving vaccines within 2 to 3 postnatal days, when they are still going through physiological postnatal weight loss. Because of the particular timing (transitioning from in utero to ex utero metabolism) and specific aspects of exposure (i.e., parenteral mode, bypassing gastroenteric barriers) and dose (related to vaccine manufacturer and with variation in birth weight), this study reveals critical issues that can modulate toxicokinetics and toxicodynamics of organomercurials in neonates.
