Folate nutrition status in mothers of the Boston birth cohort, sample of a US urban low-income population.
Researchers examined maternal folic acid supplementation and plasma folate concentrations in the Boston Birth Cohort, a predominantly urban, low-income, minority population. Their findings indicated that fewer than 5 percent of mothers in the Boston Birth Cohort started folic acid supplements before pregnancy, and approximately one third of mothers had either too low or too high plasma folate levels.

Comparing existing resources to represent dietary supplements.
Dietary supplements (DS) are widely consumed despite limited knowledge around their safety/efficacy and any well-established regulatory policies. In this pilot study, five DS resources were evaluated and compared both quantitatively and qualitatively. The authors found fragmented and inconsistent distribution of DS representation in terms of essential data elements across five resources.

Traditional Chinese medicine for acute myocardial infarction in western medicine hospitals in China.
This study examined the use of traditional Chinese medicine (TCM) in patients admitted for acute myocardial infarction (AMI) in China during the first 24 hours of hospitalization. The data came from the China Patient-centered Evaluative Assessment of Cardiac Events Retrospective Study of Acute Myocardial Infarction. A chart review was done of randomly sampled patients in 2001, 2006 and 2011 in 162 Western medicine hospitals across China. Nearly all (99%) hospitals used some form of TCM, with Salvia miltiorrhiza being the most commonly prescribed. This TCM treatment (and others) was used intravenously and use has increased over the span of the study, despite lack of evidence of benefit or harm.

Over-the-counter supplement interventions to prevent cognitive decline, mild cognitive impairment, and clinical Alzheimer-type dementia: a systematic review.
This review summarizes the evidence on efficacy and harms of over-the-counter (OTC) supplements to prevent or delay cognitive decline, mild cognitive impairment (MCI), or clinical Alzheimer-type dementia in adults with normal cognition or MCI but no dementia diagnosis. It concluded that evidence is insufficient to recommend any OTC supplement for cognitive protection in adults with normal cognition or MCI.

Effectiveness of a pediatric primary care intervention to increase maternal folate use: results from a cluster randomized controlled trial.
This study assessed the impact of provision of folate vitamins and a preconception health intervention on folate use among a group of mostly African-American and low-income mothers bringing infants to pediatric primary care. It found that among all participants, daily vitamin intake increased from baseline to 6-month follow-up (33.8 percent vs 42.6 percent).

Calcium and vitamin D use among older adults in U.S.: results from national survey.
The investigators conducted this study to describe a 10-year trend of calcium and vitamin D use from 2000 to 2009 and to evaluate age, gender, and racial disparities using national level health data. They found variability in the access to the medications, despite the observed increases associated with calcium and vitamin D supplements.

Screening for iron deficiency anemia and iron supplementation in pregnant women to improve maternal health and birth outcomes.
This case study quiz involves a 28-year-old woman presents for a routine antepartum visit. She is 33 weeks pregnant and also has a four-year-old son. She has no particular problems, and the findings from your examination are unremarkable. She asks if her blood iron level should be tested. Based on the recommendations of the U.S. Preventive Services Task Force, the quiz asks 3 questions involving screening and treatment.
