Polystyrene (PS) is an extremely stable polymer with a relatively high molecular weight and a strong hydrophobic character that makes it highly resistant to biodegradation. In this study, PS was subjected to biodegradation tests by () and () larvae. Specifically, six different experimental diets were compared: (i) fed with bran; (ii) fed only PS; (iii) fed only PS treated with HO; (iv) fed with bran; (v) fed only PS; and (vi) fed only PS treated with HO.

Purpose: Gastroenteropancreatic -neuroendocrine tumours (GEP-NETs) are commonly treated with surgical resection or long-term therapies for tumour growth control. Lutetium [Lu]-DOTA-TATE was approved for the treatment of GEP-NETs after the phase III NETTER 1trial demonstrated improved progression free survival, objective response rates and health-related quality of life (HRQoL) compared to high-dose somatostatin analogues. No real-world data exist on prescribing habits and clinically significant endpoints for [Lu]Lu-DOTA-TATE treatment in Italy.

Methods: The image-quality phantom with (b-NEMA-IQ, BMI = 29.2 kg/m) and without (NEMA-IEC, BMI = 21.
Objective: Interstitial lung disease (ILD) is the leading cause of morbidity and mortality in systemic sclerosis (SSc) patients. We aimed to investigate the impact of sex on SSc-ILD.
Methods: EUSTAR SSc patients with radiologically confirmed ILD and available percentage predicted forced vital capacity (%pFVC) were included.
