An Investigation Into What Factors Influence Patterns of Clinical Presentation in Adult-Onset Celiac Disease.

Introduction Anxiety and depression are common in patients with celiac disease (CD), and many psychosocial explanations have been considered. However, as the gut-brain axis is becoming increasingly understood, biological mechanisms have been proposed, including vitamin or mineral deficiencies and gut inflammation. Aim To investigate associations between anxiety/depression and symptom severity, vitamin status, and gut inflammation in untreated adult patients presenting with a serologic indication of celiac disease.

Colonic microbiota is associated with inflammation and host epigenomic alterations in inflammatory bowel disease.

Studies of inflammatory bowel disease (IBD) have been inconclusive in relating microbiota with distribution of inflammation. We report microbiota, host transcriptomics, epigenomics and genetics from matched inflamed and non-inflamed colonic mucosa [50 Crohn's disease (CD); 80 ulcerative colitis (UC); 31 controls]. Changes in community-wide and within-patient microbiota are linked with inflammation, but we find no evidence for a distinct microbial diagnostic signature, probably due to heterogeneous host-microbe interactions, and show only marginal microbiota associations with habitual diet.

Disseminated cryptococcal infection initially presenting as cryptococcal cellulitis in an HIV-negative patient on long-term steroids.

Cryptococcosis is an invasive fungal infection caused by encapsulated yeasts of the species. Inoculation usually occurs by inhalation through the respiratory tract, where it can then spread haematogenously to various sites, such as the central nervous system or the skin, in susceptible patients. We present the case of a 68-year-old male patient on long-term steroids who presented with a right upper limb cellulitis not responding to antibiotics.

Human-accelerated weathering increases salinization, major ions, and alkalinization in fresh water across land use.

Human-dominated land uses can increase transport of major ions in streams due to the combination of human-accelerated weathering and anthropogenic salts. Calcium, magnesium, sodium, alkalinity, and hardness significantly increased in the drinking water supply for Baltimore, Maryland over almost 50 years (p<0.05) coinciding with regional urbanization.
