Bioabfallkompost im biologischen Landbau – Auswirkungen auf die Gehalte von bioverfügbaren Schwermetallen im Boden

The accumulation of heavy metals in soils is a potential risk that may keep organic farmers from using biowaste compost. As the ecological effects of metals are related to mobile fractions rather than to total contents in the soil, we measured the total (aqua regia extractable) heavy metal contents, the readily available water soluble and the potentially bioavailable LiCl-extractable fraction of soil heavy metals in a field experiment after ten years with total applications of 95, 175 and 255 t ha-1 biowaste compost (fresh matter). Total soil contents of Cd, Cr, Cu, Ni and Pb in the compost treatments were not significantly higher than in the unfertilized control. Total Zn contents increased in the treatment with the highest application rate. In the mobile fractions Cd and Pb were not detectable. Cr, Ni and Zn contents were in the range published for unpolluted soils in other studies and did not show any differences according to treatment. Easily exchangeable Cu (in LiCl extract) was increased with compost fertilization. In several crops, lower Cd contents were measured with compost fertilization than without fertilization. Potatoes which had received mineral fertilizer had significantly higher Cd contents. Crop Zn contents were increased in the compost treatments. In conclusion, fertilization with high quality biowaste compost at such rates and after ten years of application gives no cause for concern with regard to both total heavy metal contents and available heavy metal fractions

Applying the Transtheoretical Model of Change to Consumer Debt Behavior

The Transtheoretical Model of Change (TMM) provided the framework for developing a measure to assess readiness to get out of credit card debt with consumers who are having credit card debt troubles. Key constructs of TTM include stages of change, decisional balance, self-efficacy, and processes of change. The items for the measure were developed by qualitative interviews with experts in credit counseling and consumers with debt troubles. A survey was then completed with a reliability and validity of the measure. The results have potential for use by counseling practitioners, educators and researchers

Sexual Harassments Related to Alcohol and Drugs Intake: The Experience of the Rape Centre of Turin

A cross-sectional study was conducted that describes the characteristics of sexual violence episodes related to the intake of alcohol and drugs observed among women that turned to the “Centro Soccorso Violenza Sessuale” (SVS) of the Sant’Anna Hospital in Turin between 1 January 2008, and 31 December 2017. Two hundred twenty-two patients were enrolled, 25 of which were minors, 141 were Italians, and most of them knew their aggressor and were raped in a private home. One hundred and fifty-five of them declared to the healthcare personnel to have taken alcoholic substances and/or drugs in conjunction with the event (86 reported having drunk alcohol, 36 having taken drugs and 33 disclosed both alcohol and drug abuse). If the woman knew her abuser, alcohol consumption was described as voluntary in more than 80% of cases, while in relation to drugs the consumption was equally voluntary or fraudulent. About 73% of women who reported having drunk alcohol just had amnesia or amnesia related to other symptoms, while amnesia was present in about 63% of women who reported only drug use. Physicians observed physical injuries on 156 women. Patients who reported to have assumed alcohol presented a significantly higher risk to suffer any physical injury and have a significantly increased risk to suffer injuries to their head and/or neck. The results obtained underline how even in Northern Italy alcohol intake represents the most widespread psychoactive substance in case of drug-facilitated sexual assault. There is therefore a need to promote education and prevention campaigns among citizens, especially among the youngest

Sexual Violence and Alcohol Intake: A Population-Based Explorative Study in a Northwestern Italian Area

Background and Objectives: Sexual violence (SV) is a major global public health concern. While socioeconomic factors and familial relationships have been widely reported to contribute to SV, the role of alcohol consumption should not be ignored. Indeed, alcohol can impair cognition, distort reality, increase aggression, and ease drug-facilitated sexual assault. This retrospective study aims to explore the relationship between alcohol consumption and SV by examining the prevalence, characteristics, and consequences of violence episodes. Materials and Methods: A total of 1481 women accessed the Rape Centre “Centro Soccorso Violenza Sessuale” in Turin, Italy between 2008 and 2019, with 223 reporting alcohol consumption before the assault. Results: The alcohol group had a younger age profile, predominantly within the 18–25-year-old category. SV incidents involving alcohol consumers were more likely to occur in public places or in someone else’s home, while the non-alcoholconsuming group experienced more violence in their own homes. Acquaintances and unknown individuals were primarily responsible, whereas partners were the most common perpetrators of violence against non-alcohol-consuming women. Alcohol consumers sought medical attention sooner after the assault and exhibited more symptoms and injuries, particularly of neurological origin. Concurrent use of recreational drugs was higher among alcohol consumers. The logistic regression analysis revealed higher odds of injury for Italian women and those in the 18–35 age groups after consuming alcohol. Conclusions: This study contributes to the understanding of the relationship between alcohol consumption and SV. The prevalence of alcohol-related sexual aggression is lower compared to that shown in previous studies. Nationality, age, and assailant identity influence SV dynamics. These findings can guide well-targeted interventions and prevention strategies to address SV and inform communities facing similar challenges

Tisagenlecleucel therapy for relapsed or refractory B-cell acute lymphoblastic leukaemia in infants and children younger than 3 years of age at screening : an international, multicentre, retrospective cohort study

Background Children aged younger than 3 years were excluded from the ELIANA phase 2 trial of tisagenlecleucel in children with acute lymphoblastic leukaemia. The feasibility, safety, and activity of tisagenlecleucel have not been defined in this group, the majority of whom have high-risk (KMT2A-rearranged) infant acute lymphoblastic leukaemia and historically poor outcomes despite intensification of chemotherapy, and for whom novel therapies are urgently needed. We aimed to provide real-world outcome analysis of the feasibility, activity, and safety of tisagenlecleucel in younger children and infants with acute lymphoblastic leukaemia. Methods We did an international, multicentre, retrospective cohort study at 15 hospitals across ten countries in Europe. Eligible patients were children aged younger than 3 years at screening between Sept 1, 2018, and Sept 1, 2021, who were screened for tisagenlecleucel therapy for relapsed or refractory B-cell precursor acute lymphoblastic leukaemia according to licensed indications. Patients received a single intravenous infusion of tisagenlecleucel. We tracked chimeric antigen receptor T-cell therapy outcomes using a standardised data reporting form. Overall survival, event-free survival, stringent event-free survival, B-cell aplasia, and toxicity were assessed in all patients who received a tisagenlecleucel infusion. Findings 38 eligible patients were screened, of whom 35 (92%) received a tisagenlecleucel infusion. 29 (76%) of 38 patients had KMT2A-rearranged acute lymphoblastic leukaemia, and 25 (66%) had relapsed after previous allogeneic haematopoietic stem-cell transplantation (HSCT). Patients had previously received a median of 2 lines (IQR 2-3) of (non-HSCT) therapy. Seven (18%) of 38 patients had received inotuzumab and 14 (37%) had received blinatumomab. After a median of 14 months (IQR 9-21) of follow-up, overall survival at 12 months after tisagenlecleucel infusion was 84% (64-93; five patients had died), event-free survival was 69% (47-83; nine events), and stringent event-free survival was 41% (23-58; 18 events). The probability of ongoing B-cell aplasia was 70% (95% CI 46-84; seven events) at 12 months. Adverse events included cytokine release syndrome, which occurred at any grade in 21 (60%) of 35 patients and at grade 3 or worse in five (14%), and neurotoxicity at any grade in nine (26%), none of which were severe. Measurable residual disease-negative complete response with or without haematological recovery occurred in 24 (86%) of 28 patients who had measurable disease. Interpretation These data suggest that tisagenlecleucel has antitumour activity and has an acceptable safety profile for young children and infants with B-cell precursor acute lymphoblastic leukaemia.

Opinion: Why Protect Nature? Rethinking Values and the Environment

A cornerstone of environmental policy is the debate over protecting nature for humans’ sake (instrumental values) or for nature’s (intrinsic values) (1). We propose that focusing only on instrumental or intrinsic values may fail to resonate with views on personal and collective well-being, or “what is right,” with regard to nature and the environment. Without complementary attention to other ways that value is expressed and realized by people, such a focus may inadvertently promote worldviews at odds with fair and desirable futures. It is time to engage seriously with a third class of values, one with diverse roots and current expressions: relational values. By doing so, we reframe the discussion about environmental protection, and open the door to new, potentially more productive policy approaches

Although ADCs are in the spotlight, they still present significant engineering challenges. Therefore, there is an urgent need to develop more stable and effective ADCs. Most rabbit light chains have an extra disulfide bridge, that links the variable and constant domains, between Cys80 and Cys171, which is not found in the human or mouse. Thus, to develop a new generation of ADCs, we explored the potential of rabbit-derived VL-single-domain antibody scaffolds (sdAbs) to selectively conjugate a payload to Cys80. Hence, a rabbit sdAb library directed towards canine non-Hodgkin lymphoma (cNHL) was subjected to in vitro and in vivo phage display. This allowed the identification of several highly specific VL-sdAbs, including C5, which specifically target cNHL cells in vitro and present promising in vivo tumor uptake. C5 was selected for SN-38 site-selective payload conjugation through its exposed free Cys80 to generate a stable and homogenous C5-DAB-SN-38. C5-DAB-SN-38 exhibited potent cytotoxicity activity against cNHL cells while inhibiting DNA-TopoI activity. Overall, our strategy validates a platform to develop a novel class of ADCs that combines the benefits of rabbit VL-sdAb scaffolds and the canine lymphoma model as a powerful framework for clinically translation of novel therapeutics for cancer.This work was supported by the Portuguese Funding Agency, Fundação para a Ciência e Tecnologia, FCT IP (SAICT/2017/32085, PTDC/QUI-OUT/3989/2021 and Ph.D. fellowship SFRH/BD/131468/2017 to ASA and SFRH/BD/90514/2012 to JD).
