Diphyllobothrium latum ( D. latum ) infection in humans is uncommon in the United States. Although there has been a drastic decline in the report of D. latum infection in this region, physicians should be aware of an uncommon presentation and its clinical relevance. We report a case of 55-year-old female of Ecuadorian/Peruvian origin who presented with an unknown cause of chronic right lower quadrant abdominal pain for 2 months without other particular symptoms. Initial workup revealed evidence of iron deficiency anemia, and stool occult blood test was positive...

Epidemiologic studies have reported relationships between maternal high folate and/or low B12 status during pregnancy and greater adiposity and insulin resistance in children. The goal of this study was to determine the effects of maternal folic acid supplementation (10 mg/kg diet), with (50 μg/kg diet) and without B12 , on adult, female offspring adiposity and glucose homeostasis. Female C57BL/6J mice were fed 1 of 3 diets from weaning and throughout breeding, pregnancy, and lactation: control (2 mg/kg diet folic acid, 50 μg/kg diet B12 ), supplemental folic acid with no B12 (SFA-B12 ), or supplemental folic acid with adequate B12 (SFA+B12 )...

BACKGROUND/PURPOSE: Our previous study found that 9 of 63 recurrent aphthous stomatitis (RAS)/Behcet's disease (BD) patients have serum gastric parietal cell antibody (GPCA) positivity. This study assessed whether serum GPCA positivity or RAS/BD itself was a significant factor causing hematinic deficiencies and hyperhomocysteinemia in GPCA-positive RAS/BD (GPCA+ RAS/BD) or gastric and thyroid autoantibodies-negative RAS/BD (Abs- RAS/BD) patients. METHODS: The mean blood hemoglobin (Hb), iron, vitamin B12, folic acid, and homocysteine levels were measured and compared between any two of three groups of 9 GPCA+ RAS/BD patients, 41 Abs- RAS/BD patients, and 126 healthy control subjects...

Background Methylmalonic acid (MMA) can detect functional vitamin B12 deficiencies as it accumulates early when intracellular deficits arise. However, impaired clearance of MMA from blood due to decreased glomerular filtration rate (eGFR) also results in elevated plasma MMA concentrations. Alternative to clinical trials, a data mining approach was chosen to quantify and compensate for the effect of decreased eGFR on MMA concentration. Methods Comprehensive data on patient's vitamin B12 , eGFR and MMA concentrations were collected ( n = 2906)...

The rising rates of bariatric surgery (BS) are accompanied by neurological complications related to nutrient deficiencies. One of the risk factors for neurological complications in BS patients is poor vitamin and mineral supplementation. Prevention, diagnosis and treatment of these disorders are necessary parts of lifelong care after BS. Particularly important for optimal functioning of the nervous system are vitamin B1 , B6 , B12 (cobalamin), E, copper and possibly vitamin B11 (folic acid). In this case report, we narrate about a patient with anaemia and multiple vitamin and mineral deficiencies after Roux-en-Y gastric bypass (RYGB) with an alimentary limb of 150 cm and a biliopancreatic limb of 100 cm...

Classical homocystinuria, also known as cystathionine beta synthase deficiency, is a rare disorder of methionine metabolism, leading to an abnormal accumulation of homocysteine and its metabolites in blood and urine. A young child with homocystinuria is discussed, who presented with behavioral abnormalities, involuntary movement, mental retardation, and decreased vision since birth. The diagnosis of homocystinuria was not made at initial presentation. Subtle phenotypic features with developmental delay and MRI brain finding of bilateral medially dislocated lens, eventually provided the first indication at five years of age...

Micronutrient deficiencies are common in pregnant women due to low dietary intake and increased requirements for fetal development. Low maternal micronutrient status is associated with a range of pregnancy pathologies involving placental dysfunction, including fetal growth restriction (FGR), small for gestational age (SGA), pre-eclampsia and preterm birth. However, clinical trials commonly fail to convincingly demonstrate beneficial effects of supplementation of individual micronutrients, attributed to heterogeneity and insufficient power, potential interactions and lack of mechanistic knowledge of effects on the placenta...

Gestational methyl donor (especially B9 and B12 vitamins) deficiency is involved in birth defects and brain development retardation. The underlying molecular mechanisms that are dysregulated still remain poorly understood, in particular in the cerebellum. As evidenced from previous data, females are more affected than males. In this study, we therefore took advantage of a validated rat nutritional model and performed a microarray analysis on female progeny cerebellum, in order to identify which genes and molecular pathways were disrupted in response to methyl donor deficiency...
