No cross-sectional and longitudinal association of ferritin and symptoms of attention-deficit-/hyperactivity disorder in a large population-based sample of children: Results from the GINIplus and LISAplus studies.

Attention-deficit/hyperactivity disorder (ADHD) has been associated with alterations in iron metabolism, and low ferritin concentrations in peripheral blood have inconsistently been reported in clinically referred samples of children with ADHD. This study examined whether higher peripheral concentrations of ferritin, the major iron storage protein, are associated with decreased symptoms of ADHD in 2,805 children aged 10 years participating in two large population-based birth cohorts (GINIplus and LISAplus). Whether high ferritin concentrations at age 4 months predict lower ADHD symptoms at age 10 years was also investigated using a longitudinal approach in a subsample of 193 children. No indications for an association between peripheral ferritin concentrations and ADHD symptoms were found in this large population-based study. Re-evaluating iron substitution as a therapeutic measure for ADHD may be warranted

First fossil finds of some Australian Bryozoa (Cheilostomata)

The abundant fossil record of well-preserved Bryozoa in samples from the Tertiary of Victoria and South Australia includes some \u27first fossil finds\u27 which are recorded here. Several are of species known from the Recent of the Australian or Indo-West-Pacific regions, but some represent genera with a much wider temporal and geographical range. Of the 11 species illustrated, six are known, or may be inferred, to have inhabited \u27sand fauna\u27 environments. Specimens of one species are complete enough to allow its formal description as Chlidoniopsis inopina sp. nov. <br /
