“…In the early twentieth century, McNeile and Hammett, working at hospitals in Los Angeles and Boston, compared the breast milk macronutrient composition of 8 women who consumed 1.94 g of dehydrated, encapsulated placenta per day for 11 days postpartum with that of a group of 8 women not consuming the placenta supplement and whose breast milk composition had been analyzed previously . A small discrepancy in participant dose information in this study was reported by the authors in at least 3 published papers The authors initially reported a dose of 0.6 g of placenta given 3 times daily, totaling approximately 1.8 g . Subsequent reports, however, referring to the same study, indicated a dose of 10 grains (equaling approximately 0.65 g) dehydrated placenta given 3 times daily, totaling approximately 1.94 g per day.…”

In their resulting analysis, relying solely on descriptive statistics, the authors concluded that placenta supplementation led to higher average percentages of protein and lactose and lower average percentage of fat in the milk of women supplemented with desiccated human placenta.…”

“…These findings are not consistent with the early 1900s medical literature that reported that neonatal weight gain was positively affected by postpartum supplementation with dehydrated placenta. Although decades‐old research on the effects of dehydrated placenta on neonate growth and breast milk production reported larger average neonatal weight gains and increased breast milk production in women taking placenta supplements, significant flaws in those research designs cast doubts on the validity, reliability, and generalizability of these studies’ results …”

“…In a follow‐up study, Hammett investigated the effect of ingesting desiccated human placenta on neonatal weight gain over the first 13 days postpartum. The analysis compared the weight gain of 537 neonates exclusively breastfed with 177 exclusively breastfed neonates whose mothers were fed 1.94 g per day of desiccated, encapsulated placenta . The comparative analysis, again relying solely on descriptive statistics, concluded that neonates whose mothers ingested placenta supplements showed evidence of increased average weight gain over the study period, as well as less pronounced average postnatal neonatal weight loss at day 3 postpartum, compared with neonates whose mothers were not supplemented with placenta.…”

“…Human maternal placentophagy, the postpartum ingestion of the placenta by the woman who gave birth, has become increasingly popular in recent years among some postpartum women in the United States and other industrialized countries because of its purported benefits, namely, improved mood, increased energy, and recovery of lost hormones and nutrients, among other claims, although little rigorous scientific research has evaluated these claims . Some women have also reported improved lactation after placentophagy, and previous clinical research suggested that ingesting dehydrated placenta can positively affect breast milk quality and quantity . In current practice, the placenta is often dehydrated and encapsulated to be taken as a supplement in the weeks after birth; however, little is known about the effects of encapsulated placenta supplements on breast milk quality or quantity.…”

Introduction:Clinical studies conducted in the early to mid-twentieth century, and recent self-reports by some maternal placentophagy practitioners, suggest that human maternal placentophagy improves breast milk quality and quantity, although little research has evaluated this claim. Some placentophagy providers and advocates suggest that increased prolactin levels after placenta ingestion could account for the purported lactation benefits. The current study was conducted to evaluate these claims by comparing plasma prolactin levels of women consuming steamed, dehydrated, and encapsulated placenta with those of women consuming a placebo. Neonatal weight gain was also compared between the 2 groups. Methods:A randomized, double-blind, placebo-controlled pilot trial was conducted in which postpartum women (N = 27) were given a supplement containing their dehydrated placenta (n = 12) or placebo (n = 15). Plasma prolactin concentrations were measured 4 times across late pregnancy and early postpartum, and neonatal weights were recorded 3 times over the first 3 weeks postpartum. Results:The results showed no statistically significant (P Ͻ .05) differences in either plasma prolactin levels or neonatal weight gain between groups.Discussion: Maternal consumption of steamed, dehydrated, and encapsulated placenta postpartum does not appear to affect maternal postpartum prolactin or neonatal weight in the first 3 weeks postpartum. Further research is needed to investigate the possible effects of variation in placenta preparation methods or daily intake on human lactation.

Observations on the Capacity of the Stomach in the First Ten Days of Postnatal Life

In the transition from intrauterine to extrauterine life few organs of the body are more affected than the stomach. The change influences many characters of the organ's morphology, and the position, the mass, the finer structure, and particularly the capacity are rapidly modified and adjusted to the new conditions and functions of postnatal life.The changes in gastric capacity in this period of transition have not been studied very intensively. As early as 1856 Guillot1 published some data regarding physiologic gastric capacity in the first few days of extrauterine life and this was followed somewhat later by a more extensive study by Bouchaud.2 Since that time further information on the subject has been published by Hillebrand,3 Kruger,4 Ssnitkin,5 Cammerer,6 Tuley,7 Jaschke,8 Landois9 and others. The figures presented in most of these studies are not extensive, and are usually incidental to more general studies of metabolism in the neonatal period. Much of the early work is no longer of more than historic value because the observations were made under conditions 1. Guillot, N.: De la nourrice et du nourrisson, Union m\l=e' \d., 1852, p. 61.2.

A Statistical Analysis of the Causes of Palpable Lymph Glands in the New-Born

The variation in the number of discernible lymph nodes in the new\x=req-\ born has given rise to divergent views concerning the normal occurrence. The epidermis and subcutaneous tissue of an infant are so thin and soft that a nerve or artery, a bony protuberance or tendon can readily be misinterpreted as an enlarged gland. External factors, such as coryza, infection and fever, influence the relatively unstable system of the new-born and bring about enlarged lymph nodes. Prenatal factors, such as syphilis, must also be considered. The purpose of this study is to analyze, in a carefully controlled group of cases, some of the manifold causes which give rise to the palpable glands of the new\x=req-\ born. We are grateful to the Asbury Hospital, Minneapolis, for cooperation in the collection of material, and we are also indebted to Drs. R. E. Scammon and W. P. Larson for their valuable suggestions.The results of previous work done upon this subject are somewhat antagonistic. Jensen 1 published a work upon palpation of the occipital and cervical glands of the new-born during the first nine days of life. He comes to the conclusion, after a study of 240 babies, that no patho¬ logic significance can be attached to the frequent discovery of palpable lymph nodes and that the explanation of this condition on the basis of an infection is illogical. Coerper,2 after a study of 100 new-born infants, concluded that the swelling of the glands must be due entirely to either an infection or a physiologic activity of the lymph system. Baer 3 agrees with Coerper that the palpability of peripheral glands in the new-born signifies nothing pathologic and presupposes, therefore, no preceding sickness. He also arrives at the sensible conclusion that it is extremely difficult to distinguish between normal glands which are just palpable and moderately pathologic enlargements. He advances this explanation as a reason for the variation in the results of different
