Biosensing strategies that employ readily adaptable materials for different analytes, can be miniaturized into needle electrode form, and function in bodily fluids represent a significant step toward the development of clinically relevant in vitro and in vivo sensors. In this work, a general scheme for 1st generation amperometric biosensors involving layer-by-layer electrode modification with enzyme-doped xerogels, electrochemically-deposited polymer, and polyurethane semi-permeable membranes is shown to achieve these goals. With minor modifications to these materials, sensors representing potential point-of-care medical tools are demonstrated to be sensitive and selective for a number of conditions. The potential for bedside measurements or continuous monitoring of analytes may offer faster and more accurate clinical diagnoses for diseases such as diabetes (glucose), preeclampsia (uric acid), galactosemia (galactose), xanthinuria (xanthine), and sepsis (lactate). For the specific diagnostic application, the sensing schemes have been miniaturized to wire electrodes and/or demonstrated as functional in synthetic urine or blood serum. Signal enhancement through the incorporation of platinum nanoparticle film in the scheme offers additional design control within the sensing scheme. The presented sensing strategy has the potential to be applied to any disease that has a related biomolecule and corresponding oxidase enzyme and represents rare, adaptable, sensing capabilities.

Galactosemia is a rare autosomal recessive genetic disorder that causes impaired metabolism of the carbohydrate galactose. This leads to severe liver and kidney insufficiency, central nervous system damage and long-term complications in newborns. We present two clinical cases of classical galactosemia diagnosed at the Lithuanian University of Health Sciences (LUHS) Kaunas Clinics hospital and we compare these cases in terms of clinical symptoms and genetic variation in the GALT gene. The main clinical symptoms were jaundice and hepatomegaly, significant weight loss, and lethargy. The clinical presentation of the disease in Patient 1 was more severe than that in Patient 2 due to liver failure and E. coli-induced sepsis. A novel, likely pathogenic GALT variant NM_000155.4:c.305T>C (p.Leu102Pro) was identified and we believe it could be responsible for a more severe course of the disease, although further study is needed to confirm this. It is very important to suspect and diagnose galactosemia as early in its course as possible, and introduce lactose-free formula into the patient's diet. Wide-scale newborn screening and genetic testing are particularly crucial for the early detection of the disease.
