Biodegradable plastics can enhance food waste utilization in anaerobic digestion (AD) units, but their fate under thermophilic conditions remains unclear. Previous studies using methane production, calorimetry, or spectroscopic analyses often report inconsistent results. This study tracks the biotransformation of polybutylene adipate co-terephthalate (PBAT) in thermophilic AD (55 °C) using H NMR to quantify monomers. While 1,4-butanediol degraded quickly, adipic (AA) and terephthalic acid (TPA) accumulated over time. Monomer analysis estimated PBAT biotransformation at 11.1 ± 1.9 % (TPA) and 10.1 ± 2.3 % (AA). The core microbial community remained stable, indicating intrinsic hydrolytic capacities, which were stable despite TPA and AA accumulation. This workflow provides a robust methodology to evaluate the biotransformation of plastics.

Background: Fermented foods vary significantly by food substrate and regional consumption patterns. Although they are consumed worldwide, their intake and potential health benefits remain understudied. Europe, in particular, lacks specific consumption recommendations for most fermented foods.

Background: Various media are used to enhance public understanding about diseases. While mobile health apps are widely used, there is little proof for using such apps to raise awareness of skin diseases.
Objective: We intend to develop an app, called DEDIKASI-app, to raise awareness of skin diseases, including leprosy.

Introduction: Allogeneic hematopoietic stem-cell transplantation (allo-HSCT) requires reliable vascular access for medication, transfusion, and blood sampling, which often involves painful venipuncture. This prospective study evaluated a novel dual peripherally inserted central venous catheter (PICC) technique to reduce venipuncture frequency in allo-HSCT recipients.
Methods: The study enrolled 29 allo-HSCT recipients.

Background: The "Systematic Screening of Handwriting Difficulties in Parkinson's Disease" (SOS) test is the only tool specifically designed to evaluate handwriting in people with Parkinson's Disease (pwPD). It is language specific.
Objective: To assess the construct validity, intrarater and interrater reliability of the Italian version of the SOS test.

Primary open-angle glaucoma (POAG) is characterized by chronic progressive damage to the retinal ganglion cell layer (GCL) and their axons, leading to gradual visual function loss. Currently, the gold standards for structural and functional assessment of the retina in glaucoma are static automated perimetry (SAP) and optical coherence tomography (OCT). However, in clinical practice, data from SAP and OCT may be insufficient to reliably determine the stage of glaucomatous optic neuropathy, monitor its progression, or differentiate it from other causes of visual dysfunction.
