Primary biliary cirrhosis (PBC) is an autoimmune disease of unknown etiology, often associated with other autoimmune conditions. Controlled studies have so far provided conflicting data on risk factors and comorbidity rates in PBC. We enrolled patients with PBC (n = 1032) from 23 tertiary referral centers for liver diseases in the United States and(More)
Using a genome-wide single nucleotide polymorphism (SNP) panel, we observed population structure in a diverse group of Europeans and European Americans. Under a variety of conditions and tests, there is a consistent and reproducible distinction between "northern" and "southern" European population groups: most individual participants with southern European(More)
European population genetic substructure was examined in a diverse set of >1,000 individuals of European descent, each genotyped with >300 K SNPs. Both STRUCTURE and principal component analyses (PCA) showed the largest division/principal component (PC) differentiated northern from southern European ancestry. A second PC further separated Italian, Spanish,(More)
Probiotics are defined as live microorganisms that, when administered in adequate amounts, confer a health benefit on the host, including the gastrointestinal tract. While this beneficial effect was originally thought to stem from improvements in the intestinal microbial balance, there is now substantial evidence that probiotics can also provide benefits by(More)
A genome-wide association screen for primary biliary cirrhosis risk alleles was performed in an Italian cohort. The results from the Italian cohort replicated IL12A and IL12RB associations, and a combined meta-analysis using a Canadian dataset identified newly associated loci at SPIB (P = 7.9 x 10(-11), odds ratio (OR) = 1.46), IRF5-TNPO3 (P = 2.8 x(More)
BACKGROUND A strong association between obstructive sleep apnea (OSA) and the risk for cardiovascular and cerebrovascular diseases has been reported. Continuous positive airway pressure (CPAP) is the first-line therapy for OSA, able not only to reduce daytime sleepiness but also to improve cardiovascular and metabolic outcomes. Autoadjusting CPAP (APAP), an(More)
OBJECTIVE To review the epidemiology, presentation, diagnosis, treatment, pathogenesis, and genetics of the syndrome known under the acronym of SAPHO for Synovitis, Acne, Pustulosis, Hyperostosis, and Osteitis to heighten awareness of this entity. METHODS We conducted a Medline search using SAPHO syndrome, chronic recurrent multifocal(More)
Patients with primary biliary cirrhosis (PBC) generate a variety of autoantibodies, which are primarily directed against mitochondrial antigens (AMA). However, a subgroup of patient sera are also positive for antibodies to nuclear components (ANAs). At indirect immunofluorescence (IIF), PBC sera mostly produce homogeneous, nuclear dot, speckled, centromere,(More)
BACKGROUND Epidemiology and animal models suggest that dietary monosodium glutamate (MSG) may contribute to the onset of obesity and the metabolic syndrome. METHODS Families (n = 324) from a rural area of Thailand were selected and provided MSG as the sole source for the use in meal preparation for 10 days. Three hundred forty-nine subjects aged 35-55(More)
Cells of fetal origin and cell-free fetal DNA can be detected in the maternal circulation during pregnancy, and it has recently been shown that fetal cells can persist long after delivery. Given the various biological and clinical implications of this fact, we tested the hypothesis that cell-free fetal DNA can be present in maternal plasma decades after(More)
