Vitamin B6 deficiency and diseases in elderly people--a study in nursing homes.

Background: Vitamin deficiency is a cause of health related problems in elderly people. The aims were to study associations between vitamin B6 (B6) and diseases (primarily functional gastrointestinal disorders) in elderly people in nursing homes, the prevalence of B6 deficiency and factors associated with B6 deficiency.

Methods: This cross-sectional study included residents in nursing homes.

IgG and IgG4 antibodies in subjects with irritable bowel syndrome: a case control study in the general population.

Background: Patients with Irritable Bowel Syndrome (IBS) often relate their symptoms to the intake of food and modify their diet. IgE-mediated food allergy is uncommon in IBS, but the role of IgG-mediated food hypersensitivity remains inconclusive. The primary aim of this study was to compare food- and yeast-specific IgG and IgG4 antibodies in subjects with and without IBS.

Probiotics, symptoms, and gut microbiota: what are the relations? A randomized controlled trial in subjects with irritable bowel syndrome.

Introduction. Knowledge of the mechanism of action of probiotics in subjects with irritable bowel syndrome (IBS) is imperfect. Objective.

Diet in subjects with irritable bowel syndrome: a cross-sectional study in the general population.

Background: Patients with irritable bowel syndrome (IBS) often relate symptoms to the intake of certain foods. This study assesses differences in diet in subjects with and without IBS.

Methods: The cross-sectional, population-based study was conducted in Norway in 2001.

Low intake of vitamin B6 is associated with irritable bowel syndrome symptoms.

Most subjects with irritable bowel syndrome (IBS) experience an association between symptoms and food consumption. Although dietary intake has been the focus of previous research, attention to specific nutrients has been rare. We hypothesized that there is an association between the severity of IBS symptoms and the intake of specific food groups and specific nutrients.

A candidate probiotic with unfavourable effects in subjects with irritable bowel syndrome: a randomised controlled trial.

Background: Some probiotics have shown efficacy for patients with irritable bowel syndrome (IBS). Lactobacillus (L.) plantarum MF1298 was found to have the best in vitro probiotic properties of 22 strains of lactobacilli.
