Myrciaria dubia (camu-camu) is an Amazon tree that produces a tart fruit with high vitamin C content. It is probably the fruit with the highest vitamin C content among all Brazilian fruit crops and it can be used to supplement daily vitamin C dose. This property has attracted the attention of consumers and, consequently, encouraged fruit farmers to produce it. In order to identify and select potential accessions for commercial exploitation and breeding programs, M. dubia has received considerable research attention...

Objective: To evaluate the impact of clinical decision support (CDS) tools on rates of vitamin D testing. Screening for vitamin D deficiency has increased in recent years, spurred by studies suggesting vitamin D's clinical benefits. Such screening, however, is often unsupported by evidence and can incur unnecessary costs. Materials and Methods: We evaluated how rates of vitamin D screening changed after we implemented 3 CDS tools in the electronic health record (EHR) of a large health plan: (1) a new vitamin D screening guideline, (2) an alert that requires clinician acknowledgement of current guidelines to continue ordering the test (a "hard stop"), and (3) a modification of laboratory ordering preference lists that eliminates shortcuts...

NAD (Nicotinamide Adenine Dinucleotide) biosynthesis is vital for bacterial physiology and plays an important role in cellular metabolism. A naturally occurring vitamin B complex, niacin (nicotinic acid), is a precursor of coenzymes NAD and NADP. Here, we study the impact of niacin on global gene expression of Streptococcus pneumoniae D39 and elucidate the role of NiaR as a transcriptional regulator of niaX, nadC, and pnuC. Transcriptome comparison of the D39 wild-type grown in chemically defined medium (CDM) with 0 to 10 mM niacin revealed elevated expression of various genes, including niaX, nadC, pnuC, fba, rex, gapN, pncB, gap, adhE, and adhB2 that are putatively involved in the transport and utilization of niacin...

Vitamin B12 (B12) adequacy during pregnancy is crucial for maternal health and optimal fetal development; however, suboptimal B12 status has been reported in pregnant Canadian women. Methylmalonic acid (MMA) is a sensitive indicator of B12 status. Since few studies have measured MMA during pregnancy in Canadian women, the objective of this study was to evaluate B12 status in pregnant women living in Metro Vancouver, using both plasma total B12 and MMA. We recruited a convenience sample of 320 pregnant women between 20 and 35 gestational weeks from local healthcare facilities...

Vitamin B12 deficiency is a known cause of megaloblastic anemia and bone marrow failure. Bone marrow biopsies are not frequently performed as part of the diagnostic workup and can demonstrate morphologic features that overlap with myelodysplastic syndrome (MDS) and acute leukemia. We describe a case of a dysplastic bone marrow with increased bone marrow hematogones detected by flow cytometry in a child with vitamin B12 deficiency. Hematogones are normal B cell precursors, and hyperplasia has been described in a variety of often reactive conditions and also disease...

Standardization of 25-hydroxyvitamin D (25OHD) values is still a challenge. We propose standardization by correction of the measured 25OHD values using the linear regression bias from the National Institute of Standards and Technology (NIST) 'total' target values reported by Vitamin D External Quality Assessment Scheme (DEQAS). Our approach could perhaps be a practical solution to the anomaly surrounding non-standardized 25OHD values. INTRODUCTION: Standardization of 25OHD values is still a challenge...
