Choline (a nutrient found in beef liver, chicken liver, eggs, bacon and pork) status in pregnant moms has been found to affect cortisol levels in newborns. According to a study published by Jiang X, Yan et al., http://lib.bioinfo.pl/paper:22418088, these pregnant women were given either 930 or 480 mg/day of choline in their third trimester for 12 weeks.

The fact sheet for Babesia is up today. Here are a few (disturbing) highlights:
1. Babesia is a parasite that attacks red blood cells. There are three ways Babesia spreads: 1) Through the bite of the blacklegged tick (or deer tick, Ixodes scapularis–the same tick that carries Lyme/B. burgdorferi); 2) Through blood transfusions with contaminated donated blood; 3) From mother to baby during pregnancy or childbirth.
2. The tick that carries Babesia is most likely to infect humans when it’s in its nymphal stage. During this stage, the tick is about the size of a poppy seed. (Maybe this is one reason why Babesia cases are on the rise among older people–they probably have trouble spotting ticks that small!)
3. Many people who have a Babesia infection don’t show any symptoms. When they do show symptoms, they can include fever, chills, sweats, headache, body aches, loss of appetite, nausea, and fatigue. Some develop hemolytic anemia, which causes jaundice and dark urine.
4. Babesia can be deadly if it goes untreated. Here are some possible complications: low and unstable blood pressure; altered mental status; severe hemolytic anemia (hemolysis); very low platelet count (thrombocytopenia); disseminated intravascular coagulation (also known as “DIC” or consumptive coagulopathy), which can lead to blood clots and bleeding; and malfunction of vital organs (such as the kidneys, liver, lungs, and heart).
5. There are two main treatment options for Babesia: a combination of Mepron and Zithromax OR a combination of Clindamycin and Quinine. Children and women who are pregnant should probably not be treated with Mepron.To read more about treatment, go to the Babesia fact sheet.
6. Babesia is sometimes confused with Malaria because they look similar under a microscope and can have similar symptoms. To avoid confusion, doctors should order multiple types of tests for Babesia if patients show symptoms. To read more about available tests, see the fact sheet.
7. There are 4 identified species of Babesia that infect humans: Babesia microti, B. divergens, B. duncani (WA-1), and MO-1 (unnamed strain). Antibody tests for Babesia are species specific, so if you have B. microti and you are tested for B. duncani, the test will come back negative. This means that patients need to undergo multiple blood tests!
8. Even though Babesia infection is known to be transmitted through blood transfusion (As of Sept. 2011, the CDC has identified 159 cases, and at least 12 of those people have died.), donated blood is not tested for Babesia! Donors are asked to fill out a questionnaire asking whether they have Babesia (not whether they’ve had tick bites or Babesia-like symptoms). In other words, we are relying on patient self-reporting to screen the blood supply for this parasite! (Why they don’t screen out all people who’ve had tick bites is beyond me.) The CDC’s response as to whether they will implement testing of donated blood for Babesia in the future: Maybe. They say they are going to “Monitor reports of tick-borne infection to determine if the disease is spreading to other parts of the country and to identify emerging strains of Babesia that may cause human disease.” In other words, they’re going to wait to see how bad it gets before they do anything about the blood supply. Some organizations like the Rhode Island Blood Center have begun screening blood for Babesia using an experimental test, but this is not mandated by CDC policy.
This might prompt you to ask: What are my local health department, hospitals, and blood donation organizations doing about Babesia in the blood supply?
