“…The baseline serum retinol levels of the study control and supplemented groups are similar to those reported by Fernandes et al [30]; Lima et al [10] and Grilo et al [25], who studied women from the Brazilian northeast region. However, the baseline serum retinol levels of the study control and supplemented groups were higher than those found in India [31], Africa, [32,33], and Ethiopia [34] as these countries have high prevalence of vitamin A deficiency, and in Germany [35], probably because of the very different sample size.…”

Vitamin A and E are important during pregnancy, the neonatal period, and childhood.The objective of this study was to assess whether maternal RRR-α-tocopherol supplementation affects serum and breast milk retinol. Serum was collected at baseline and twenty days later, and breast milk, at baseline, and on days 1, 7, and 20 after delivery.After the baseline serum collection, the supplemented group (n=16) received a single 400 IU of RRR-α-tocopherol. The control group (n=18) was only performed collections.Retinol and alpha tocopherol levels were determined by liquid chromatography. Serum retinol and alpha tocopherol at baseline and 20 days after delivery indicated proper vitamin A (> 20 µg/dL) and E (> 516 μg/dL) statuses in the control and supplemented groups (p > 0.05). Colostrum retinol levels on days 1 and 7 after delivery were significantly higher in the supplemented group (p = 0.018 and p = 0.012, respectively).Maternal vitamin E supplementation increased colostrum retinol by 52.23% and 111.2%, 24 hours and 7 days, respectively. However, retinol in mature milk did not differ between the groups (p > 0.05). In conclusion, the supplementation with 400 IU of RRR-α-tocopherol improved vitamin A bioavailability in breast milk.

“…Maternal age and lactation duration are factors known to affect other aspects of lactation and milk quality (28)(29)(30), so it was reasonable to probe our data for evidence of an association with osmolality. Likely, due to the intrinsically narrow distribution of Mosm it is not a readily scalable variable.…”

Background: It has been demonstrated that human milk osmolality (Mosm) is regulated within an established range, typically 290 to 300 mOsm/kg, and appears to be resistant to effects of maternal dehydration, as refl ected by high urinary osmolality (Uosm). Objective: To determine the degree of association between Mosm and Uosm at a common point in time, as well as the reproducibility of both measures over a one-week interval of sampling. Methods: Mosm and Uosm were measured with a Vogel Löser 450 osmometer on samples of the respective biological fl uids collected concurrently in 31 lactating women, with infants aged between 30 and 340 days. In the fi rst 15 women recruited, collections were repeated 7 days after the initial ones. Results: The median Mosm for the 46 samples collected was 308 mOsm/kg with a range from 288 to 448 mOsm/kg. The corresponding values for Uosm were 598 mOsm/kg with a range from 93 to 1,678 mOsm/kg. The Spearman rank-order correlation coeffi cient for within-individual association of Mosm and Uosm was r = 0.214 (p = 0.153). The median Mosm for the 15 repeat-subjects was 309 mOsm/kg on both occasions, with a within-individual Spearman coeffi cient of r = 0.326 (p = 0.118). By contrast, for the Uosm, the within-subject association was much stronger, with r = 0.699 (p = 0.002). Conclusions: The osmometry technique proved to be a highly stable and reproducible measurement technique. Mosm and Uosm are not signifi cantly associated at a point in time. Intra-subject Mosm varies more across time than intra-subject Uosm.

“…A alta concentração de vitaminas no colostro pode ser um mecanismo compensatório para complementar os neonatos com vitaminas que exibem atividade antioxidante (SZLAGATYS-SIDORKIEWICZ et al, 2012). Lima et al (2014) realizou uma revisão teórica com base em 25 artigos científicos, no qual concluiu que a concentração de vitamina E diminui durante a lactação, até atingir a fase de leite maduro. A mesma pesquisa elucida que a dieta materna não influencia nas concentrações desta vitamina.…”
