Abstract
This study investigated the release of microplastics and nanoplastics from plastic containers and reusable food pouches under different usage scenarios, using DI water and 3% acetic acid as food simulants for aqueous foods and acidic foods. The results indicated that microwave heating caused the highest release of microplastics and nanoplastics into food compared to other usage scenarios, such as refrigeration or room-temperature storage. It was found that some containers could release as many as 4.22 million microplastic and 2.11 billion nanoplastic particles from only one square centimeter of plastic area within 3 min of microwave heating. Refrigeration and room-temperature storage for over six months can also release millions to billions of microplastics and nanoplastics. Additionally, the polyethylene-based food pouch released more particles than polypropylene-based plastic containers. Exposure modeling results suggested that the highest estimated daily intake was 20.3 ng/kg·day for infants drinking microwaved water and 22.1 ng/kg·day for toddlers consuming microwaved dairy products from polypropylene containers. Furthermore, an in vitro study conducted to assess the cell viability showed that the extracted microplastics and nanoplastics released from the plastic container can cause the death of 76.70 and 77.18% of human embryonic kidney cells (HEK293T) at 1000 μg/mL concentration after exposure of 48 and 72 h, respectively.

Abstract
PURPOSE Acute respiratory distress syndrome, with the need for invasive mechanical ventilation (MV) remains a major cause of neonatal mortality and morbidity. Although venovenous extracorporeal lung support (VV-ECLS) has become a standard of care procedure in neonatal patients with acute pulmonary failure there are no reports regarding the use of a double-lumen cannula for extracorporeal minimal invasive lung support via the umbilical vein. METHODS A neonatal lamb model was used (n = 3). Umbilical vein was cannulated with a double-lumen catheter allowing venovenous extracorporeal gas exchange. Cannula was positioned with its tip in the right atrium. VV-ECLS was started and ventilation was stopped. Providing oxygenation and CO2 removal solely through VV-ECLS hemodynamics, blood gases were measured. RESULTS Total VV-ECLS without MV was applied to all three neonatal lambs. Time on venovenous ECLS was 60, 120 and 120 min. Initial pCO2 was 60, 56 and 65 mmHg compared to 31, 32 and 32 mmHg at the end of VV-ECLS. Initial pO2 was 30, 27 and 26 mmHg compared to 22, 19 and 23 mmHg. Initial lactate was 5, 10 and 3.7 mmol/l compared to 13.3, 12.6 and 11.3 mmol/l at the end of VV-ECLS. MAP at baseline was 51, 52 and 65 mmHg compared to 36, 38 and 41 mmHg at the end of VV-ECLS. In all three lambs inotropes were admitted to maintain MAD >35 mmHg. CONCLUSION Even without mechanical ventilation we were able to sufficiently remove pCO2 with our new minimal invasive VV-ECLS using a double-lumen catheter via the umbilical vein, supporting the idea of a lung protective strategy in neonatal acute respiratory failure. pO2 was measured 22, 19 and 23 mmHg, respectively, at the end of VV-ECLS, at least partially caused by recirculation phenomenon, which could possibly be improved by different cannula design. Inotropic support was necessary during VV-ECLS to achieve targeted MAD > 35 mmHg. While technically feasible, this new approach might allow further research in the field of extracorporeal lung support and therefore will follow the concept of a lung protective strategy in acute neonatal respiratory failure.

Abstract
BACKGROUND This study aimed to determine the impact of prior surgery on the feasibility of laparoscopic surgery for children. METHODS A prospective study analyzed 471 consecutive children who underwent laparoscopic surgery over a 4-year period. Laparoscopic procedures were classified "easy," "difficult," or "demanding." The end points of the study were conversion rate, intraoperative events, and duration of operation. RESULTS A total of 89 patients (19%) had undergone previous abdominal surgery. The conversion rate was 18% for the patients with prior surgery versus 9% for those without a prior operation (16/89 vs 35/382; p < 0.05). This difference reflects a significantly higher conversion rate for "easy" procedures among patients with than among those without prior surgery, but not for "difficult" and "demanding" procedures. The type of prior surgery had no significant impact on the mean duration of the operation. Of 71 procedures, 12 (17%) after prior conventional surgery were converted, as compared with 4 (22%) of 18 after prior laparoscopy (p > 0.05). Intraoperative events, mainly attributable to adhesions and lack of overview, occurred in 8% of patients with prior procedures, as compared with 2% without former surgery (7/89 vs 9/382; p < 0.05). Relevant complications were not significantly more frequent after prior surgery. The incidence of conversions decreased with increased time between current and previous surgery. It was 64% for surgeries less than 1 year later, 25% for surgeries 1 to 5 years later, and 5% for surgeries more than 5 years later (7/11 vs 6/24 vs 3/54; p < 0.001). CONCLUSIONS Prior surgery has a limited impact on the feasibility of laparoscopic surgery for children. The conversion rate and the incidence of intraoperative events, mainly because of adhesions and lack of overviewing, is increased, but not the incidence of relevant complications. The feasibility improves considerably with increased time between surgery and prior surgery. The authors consider laparoscopy to be the first-choice technique after prior surgery.

Abstract
8502 Background: Patients undergoing cancer treatment often report cognitive impairment, manifested as problems with concentration and memory. Such cognitive problems may be noticed only by the patient. The purpose of this multicenter longitudinal study was to investigate the frequency and severity of self-reported problems with memory and concentration over time. Methods: Patients undergoing treatment for solid tumors self-rated problems with memory and concentration using an 11-point Likert Scale (0 = Not present to 10 = “As bad as you can imagine”) at baseline before treatment began (T1), at their worst during treatment (T2), and at 6 months following treatment (T3). Any symptom level ≥ 7 was classified as “severe.” T-tests, paired or independent as appropriate, were used to examine differences in symptoms over time and between patients treated with and without chemotherapy. Results: Of 595 participants, 356 (60%) received chemotherapy, with or without radiation and 239 (40%) radiation alone. Concentration problems were reported by 48% of all participants at T1 (5% severe), 67% at T2 (18% severe) and 58% (8% severe) at T3 (p < .001). Memory loss was reported by 53% at T1 (4% severe), 67% (18% severe) at T2 and 68% (11% severe) at T3 (p < .001). The average frequency and severity of both symptoms in patients receiving chemotherapy increased significantly between T1 and T2 (p<.001). Both symptoms were less severe in patients receiving radiation alone at all three measurements (all ps<.001). Symptoms at T3 were significantly higher than T1 for both groups (p<.001). Conclusion: Self-reported problems with memory and concentration are experienced by the majority of cancer patients who receive chemotherapy and radiation. The cognitive problems get worse during treatment and persist at least 6 months following. Controlled studies of interventions for problems of memory loss and concentration are warranted.
