Background: At the start of their work, the European Bioanalysis Forum dried blood spots microsampling consortium did not form a dedicated team to investigate the spot homogeneity. However, two teams performed experiments that produced results relating to sample homogeneity.
Results: The data, which were produced via two different approaches (a radiolabeled and a nonradiolabeled approach), are highly complementary and demonstrate clear effects on sample inhomogeneity due to the substrate type, compound and hematocrit levels.
Conclusion: The results demonstrate that sample inhomogeneity is a significant hurdle to the use of dried blood spots for regulated bioanalysis that should be investigated further in the method establishment phase if the whole spot is not sampled.

The European Commission authorized the use of dried yellow mealworm (Tenebrio molitor - TM) as a food ingredient under Regulation EU 2021/882. As TM emerges as an important allergen source, sensitization and allergy to TM in various populations need investigation. The aim of this study was to assess the incidence of sensitization to TM before its introduction as a food ingredient in Poland, as well as checking the occurrence of co-sensitivity to TM and other invertebrate allergenic extracts and molecules.

Background: Newborn screening (NBS) is a simple, non-invasive test that allows for the early identification of genetic diseases within the first days of a newborn's life. The aim of NBS is to detect potentially fatal or disabling conditions in newborns as early as possible, before the onset of disease symptoms. Early diagnosis enables timely treatments and improves the quality of life for affected patients.

Hesperidin exhibits promising potential as a feed additive for augmenting gastric acid secretion in animals. Gastrointestinal function is essential for animal growth and the efficient digestion of dietary nutrients, with gastric acid secretion serving as one of its critical components. The secretion of gastric acid, together with other digestive fluids and substances, significantly influences the digestion and absorption of animal feed, which in turn affects growth performance.

Multiple sulfatase deficiency (MSD) is an ultra-rare lysosomal disease caused by defective activation of cellular sulfatases comprising clinical features of mucopolysaccharidoses, sphingolipidoses, and other sulfatase deficiencies. We present a case of an infant with feeding difficulties related to autism spectrum disorder (ASD) who was diagnosed at 10 months of age with MSD by next-generation sequencing (NGS). Biochemical results obtained in dried blood spot (DBS) samples were inconsistent and not suggesting MSD in the light of identified pathogenic SUMF1 variants.
