Natalizumab is a monoclonal antibody that is only used in humans with multiple sclerosis.  It is somewhat toxic, and we were interested to see if this large monoclonal antibody transfers into human milk.  Levels in milk appear low,  but I made a mistake in the timing of the study, and should have drawn milk levels several months longer.  I need to redo this study and go out to about 120 days.   However, at this point, I still think milk levels are subclinical.   TW

One of the most consistent rumors in human lactation for the last 30 years, has been that sore nipples are often caused by Candia Albicans infections.  Several of us have published that his etiology of sore nipples is completely wrong,  but this "syndrome" continues to be discussed in the beastfeeding field.  This study below, again,  clearly suggests that Candida as a cause of sore nipples,  is wrong.  Sorry folks,  its something else.   TWH

Nothing is more important for a fetus than the adequate control of blood pressure in the mom.  We are seeing hypertension more and more often today in pregnant women as the rate of obesity has risen.  This study reviews treatment of hypertension in pregnant women.  TWH

B12 is a really critical vitamin,  particularly in pregnant and breastfeeding women.  We've known for a long time that women who are vegetarians have a higher risk of B12 deficiency,  which may impact their fetus, and breastfed infants.
