Early Onset Active Inflammatory Bowel Disease Is Associated With Psychiatric Comorbidities: A Multi-Network Propensity-Matched Cohort Study.

Background: Psychiatric disease burden in patients with Inflammatory bowel disease (IBD) has risen substantially over the past few decades. However, there is limited data on the relationship between IBD disease activity and the incidence of psychiatric comorbidities. We sought to conduct a population-based study to investigate the impact of early onset disease activity in newly diagnosed IBD patients on psychiatric disease diagnoses and medication usage.

Omega-3 Levels in Prenatal Supplements.

Objective:  This study aimed to systematically document the reported omega-3 levels in commercially available prenatal supplements in the United States and Canada, and compare these levels to recommended intakes in pregnancy.

Study Design:  Commercial prenatal supplements were identified using the Dietary Supplement Label Database ( = 50) and the Licensed Natural Health Products Database ( = 18). Mean omega-3 levels and the proportion of products meeting recommendations for pregnant women were tabulated.

Evolution of Large Eyes in Stromboidea (Gastropoda): Impact of Photic Environment and Life History Traits.

Eyes within the marine gastropod superfamily Stromboidea range widely in size, from 0.2 to 2.3 mm - the largest eyes known in any gastropod.

Iron-Catalyzed Transfer Hydrogenation of Allylic Alcohols with Isopropanol.

Herein, we report an iron-catalyzed transfer hydrogenation of allylic alcohols. The operationally simple protocol employs a well-defined bench stable (cyclopentadienone)iron(0) carbonyl complex as a precatalyst in combination with KCO (4 mol %) and isopropanol as the hydrogen donor. A diverse range of allylic alcohols undergo transfer hydrogenation to form the corresponding alcohols in good yields (33 examples, ≤83% isolated yield).
