    This study aimed to observe the impact of the COVID-19 outbreak on acute general surgery in the first German "hotspot" regions of Heinsberg and Aachen, during the first months of the pandemic. The incidence and severity of acute appendicitis, acute cholecystitis and mechanical bowel obstruction, were compared between March and May 2020 and a control period (same months of the previous three years). Pre-, intra- and postoperative data was compared between three regional hospitals of Heinsberg and the closest maximum care, university hospital. A total of 592 operated patients were included, 141 belonging to the pandemic cohort and 451 to the historic cohort. The pandemic group showed higher rates of clinical peritonitis (38% vs. 27%, p = 0.015), higher rates of mean white blood cell count (13.2±4.4 /nl vs. 12.3±4.7 /nl, p = 0.044) and mean C-reactive protein (60.3±81.1 mg/l vs. 44.4±72.6 mg/l, p = 0.015) preoperatively. Specifically in patients with acute appendicitis, there were less patients with catarrhal appendicitis (23% vs. 35%, p = 0.021) and a tendency towards more advanced histological findings in the pandemic cohort. In the university hospital, a 42% reduction in acute operated cases was observed at the onset of the pandemic (n = 30 in 2020 vs. n = 52 in 2019), whereas in the peripheral hospitals of Heinsberg there was only a 10% reduction (n = 111 in 2020 vs. n = 123 in 2019). The onset of the COVID-19 pandemic in our region was accompanied by advanced preoperative and intraoperative findings in patients undergoing emergency general surgery. A greater reduction in acute operated surgical cases was observed at the university hospital, in contrast to the smaller hospitals of Heinsberg, suggesting a possible shift of emergency patients, requiring immediate operation, from maximum care hospital to the periphery

    Safety assessment of the process Green Loop System, used to recycle polycyclohexylene dimethylene terephthalate glycol-modified (PCTG) plates for use as food contact materials

    The EFSA Panel on Food Contact Materials, Enzymes and Processing Aids (CEP) assessed the safety of the recycling process Green Loop System (EU register number RECYC174), a closed and controlled product loop. The input consists of washed plates of polycyclohexylene dimethylene terephthalate glycol-modified (PCTG) having been used in, e.g. canteens. The plates are ground, converted to new plates, returned to the users of the loop and used as before recycling. The management system to ensure a closed loop is critical, i.e. compliance of the origin of the input with Commission Regulation (EC) No 282/2008 and full traceability from input to final product should be ensured. The Panel concluded that the input of the process Green Loop System originates from product loops that are in a closed and controlled chain, designed to ensure that only materials and articles that have been intended for food contact are used and that contamination other than by food can be ruled out. The recycling process Green Loop System is, therefore, able to recycle PCTG plates intended for repeated use, for contact with aqueous, acidic and fatty food, at low and high temperatures
