OBJECTIVE: To assess the effectiveness of conservative therapy in carpal tunnel syndrome. DATA SOURCES: A computer-aided search of MEDLINE and the Cochrane Collaboration was conducted for randomized controlled trials (RCTs) from January 1985 to May 2006. REVIEW METHODS: RCTs were included if: (1) the patients, with clinically and electrophysiologically confirmed carpal tunnel syndrome, had not previously undergone surgical release, (2) the efficacy of one or more conservative treatment options was evaluated, (3) the study was designed as a randomized controlled trial.

BACKGROUND: Nausea, retching and vomiting are very commonly experienced by women in early pregnancy. There are considerable physical and psychological effects on women who experience these symptoms. This is an update of a review of interventions for nausea and vomiting in early pregnancy previously published in 2003. OBJECTIVES: To assess the effectiveness and safety of all interventions for nausea, vomiting and retching in early pregnancy, up to 20 weeks' gestation. SEARCH STRATEGY: We searched the Cochrane Pregnancy and Childbirth Group's Trials Register (28 May 2010).

BACKGROUND: A vegetarian diet is considered to promote health and longevity and reduce the risk of cardiovascular diseases and cancer. However, a vegetarian diet may be deficient in some nutrients. Exclusion of animal products in vegetarian diets may affect the status of certain B-vitamins, and further cause the rise of plasma homocysteine concentration. OBJECTIVE: The nutritional status of various B-vitamins (B(1), B(2), B(6), B(12), folic acid) and the concentration of homocysteine in blood plasma of omnivores (n = 40), vegetarians (n = 36) and vegans (n = 42) in Austria was evaluated.

Metabolic syndrome (MetS) represents a cluster of risk factors for atherosclerosis and is considered a risk factor for cardiovascular disease. The role of diet in the etiology of MetS is poorly understood, especially among Asian subjects. This cross-sectional study assessed the relationship between diet and the number of MetS components among Japanese men (n=609) and women (n=631). Mean (s.d.) age and body mass index were 57.1 (12.1) years and 22.8 (2.8) kg m(-2) for men and 55.5 (12.0) years and 22.0 (3.0) kg m(-2) for women, respectively.

Addiction research focusing on homocysteine metabolism and its association with aspects of alcohol dependence has revealed important findings. Recent literature on this topic has been taken into account for the review provided. Methylenetetrahydrofolate reductase (MTHFR) is a key enzyme in the homocysteine metabolism. Plasma homocysteine levels are influenced by the single-nucleotide polymorphism (SNP) MTHFR C677T. Besides genetic factors, environmental factors have an impact on homocysteine plasma levels too.

OBJECTIVE: To examine the relationship between adherence to prescribed folic acid supplements and folic acid intake, serum folate and plasma homocysteine in hemodialysis patients. The effects of change in adherence patterns from enrollment to 1 year later on changes in these same measures were also assessed. DESIGN: Secondary data analysis. PARTICIPANTS: Eighty-six hemodialysis patients who participated in the Hemodialysis (HEMO) Study's Homocysteine ancillary study. MAIN OUTCOME MEASURES: Folic acid supplement intake, serum folate, and plasma homocysteine.

OBJECTIVE: Folate and other methyl-group nutrients may play a key role in pancreatic carcinogenesis through their effects on DNA integrity. We examined the association between pancreatic cancer and intake of folate, vitamins B(6), B(12) and methionine in a large population-based case-control study. METHODS: Risk factor data were collected during in-person interviews with 532 pancreatic cancer cases diagnosed in 1995-1999 and 1,701 frequency-matched controls in the San Francisco Bay Area.

BACKGROUND: Bariatric surgery is widely performed to induce weight loss. OBJECTIVE: The objective was to examine changes in vitamin status after 2 bariatric surgical techniques. DESIGN: A randomized controlled trial was conducted in 2 Scandinavian hospitals. The subjects were 60 superobese patients [body mass index (BMI; in kg/m(2)): 50-60]. The surgical interventions were either laparoscopic Roux-en-Y gastric bypass or laparoscopic biliopancreatic diversion with duodenal switch. All patients received multivitamins, iron, calcium, and vitamin D supplements.
