Polymorphisms in genes involved in folate metabolism modify the association of dietary and circulating folate and vitamin B-6 with cervical neoplasia

submitted by: LUCIANA TOMITA
High folate intake has been suggested as an important factor for cancer prevention; however, previous studies on the relationship between folate intake, serum folate and plasma homocysteine are controversial. We conducted a hospital-based, case-control study in Brazil investigating associations between dietary and circulating vitamins B-6, B-12 and folate, homocysteine, genotypes of folate-metabolizing enzyme methylenetetrahydrofolate reductase [MTHFR C677T, A1298C],...

Zinc supplementation improves bone density in patients with thalassemia: a double-blind, randomized, placebo-controlled trial

submitted by: efung
BACKGROUND: Patients with thalassemia major (Thal) frequently have low plasma zinc, which has been associated with low bone mass. OBJECTIVE: The objective was to determine the effect of zinc supplementation on bone mass in patients with Thal. DESIGN: Forty-two subjects (21 females aged 10-30 y) with Thal and low bone mass were randomly assigned to receive 25 mg Zn/d or placebo. Bone mineral content (BMC) and areal bone mineral density (aBMD) were assessed by using dual-energy X-ray...

History of Medicine. Plague and Vampirism in the Middle Ages.

submitted by: camdic
The Nachzehrer would be a special kind of vampire who lives in a constant state of numbness in his grave, without understanding what is happening around and just like a child, chewing spasmodically his dress. Martin Böhm wrote in 1601: "We have seen in times of the plague how dead people especially women - who have died of the plague make smacking noises in their graves, like a pig that is eating, and that while this smacking is going on the plague becomes much worse, usually in the...

MWV #81 - Sheldon Campbell - The Singing Microbiologist

submitted by: MicrobeWorld
Sheldon Campbell sings about microbiology. Dr. Campbell teaches microbiology at Yale School of Medicine and he uses music to enhance his lectures. He has one song for every block of lectures he gives on a major topic. Songs he's written include a song about fungi, tick borne disease, tuberculosis and one that reviews all of microbiology in eight minutes. Dr. Campbell hasn't done any testing to see his songs are more effective at getting his message across but he does get the occasional...

Maternal knowledge following nutrition behavior change communication is conditional upon both health workers’ knowledge and knowledge sharing efficacy in rural Haiti

submitted by: mduduzi
In the context of a food assistance program in rural Haiti, we developed measures of the effectiveness of community health worker (CHW)-delivered behavior change communication (BCC). We administered knowledge tests to 954 mothers and 38 CHWs to define 4 measures: CHW knowledge, maternal knowledge, knowledge-sharing efficacy (proportion of CHW knowledge shared), and shared correct knowledge between the CHWs and the mothers with whom they interacted. On the basis of the tests, CHWs had high...
