Daily Intake of a Functional Synbiotic Yogurt Increases Calcium Absorption in Young Adult Women.
Cornes R, Sintes C, Peña A, Albin S, O'Brien KO, Abrams SA, Donangelo CM. Cornes R, et al. Among authors: o brien ko. J Nutr. 2022 Jul 6;152(7):1647-1654. doi: 10.1093/jn/nxac088. J Nutr. 2022. PMID: 35411924 Free article.
Responders had higher vegetable intake (P = 0.03), tended to have higher potassium and calcium intakes (P 0.08), and had higher total body BMD (P = 0.09), than nonresponders. CONCLUSIONS: Short-term daily consumption of a synbiotic yogurt enhanced calcium absorption relati …

PMID: 35533239 Free Books & Documents. Review.

The evidence comparing never being fed human milk with being fed human milk for shorter-term durations (i.e., < 6 months) and risk of childhood leukemia is mixed. However, the evidence comparing never being fed human milk with being fed human milk for longer-term

Maternal inflammation at delivery affects assessment of maternal iron status.
Lee S, Guillet R, Cooper EM, Westerman M, Orlando M, Pressman E, O'Brien KO. Lee S, et al. Among authors: o brien ko. J Nutr. 2014 Oct;144(10):1524-32. doi: 10.3945/jn.114.191445. Epub 2014 Jul 30. J Nutr. 2014. PMID: 25080540 Free article.
EPO is a sensitive indicator of iron status across gestation, is not affected by systemic inflammation, and may better predict risk of anemia at term. The trial was registered at clinicaltrials.gov as NCT01019902....

Placental heme receptor LRP1 correlates with the heme exporter FLVCR1 and neonatal iron status.
Cao C, Pressman EK, Cooper EM, Guillet R, Westerman M, O'Brien KO. Cao C, et al. Among authors: o brien ko. Reproduction. 2014 Sep;148(3):295-302. doi: 10.1530/REP-14-0053. Epub 2014 Jun 19. Reproduction. 2014. PMID: 24947444 Free PMC article.
Placental LRP1 protein expression was significantly higher in women who exhibited greater decreases in serum Hx from mid-gestation to term (r=0.28, P=0.04). Significant associations were also found between placental LRP1 protein with cord hepcidin (r=-0.29, P=0.03) and pla …
