Are citizens willing to pay for the ecosystem services supported by Common Agricultural Policy? A non-market valuation by choice experiment.

Public attention to the impact of human activities on the environment is growing over time across several sectors, particularly agri-food. In Europe, the agricultural sector's focus on sustainability has influenced EU policies for at least 40 years. The Common Agricultural Policy (CAP) has for years been proposing tools, commitments, and incentives to mitigate the over-use of natural resources and to increase or maintain the flow of ecosystem services (ES) provide by agro-ecosystems. In the latest reform (23-27), the EU strengthens the commitments required of farmers for environmental issues. The role of farmers in natural capital management and ES provision seems to be recognized, EU subsidies for farmers seem to be more related to sustainability and well-being concerns of European citizen. However, it is necessary to understand whether society recognizes these benefits and legitimizes this transfer of public money for these purposes. This study aims to evaluate non-farmers citizen preference through a Choice Experiment for the potential higher flows of ES provided by three of the reformulated and new Good Agricultural Environmental Conditions - GAEC. The case study developed in Italy collected data from 185 citizens of the Po Valley, one of the most intensely cultivated areas in Europe. Analyses demonstrated how society recognizes the benefits provided by more sustainable agricultural systems, showing a preference for higher ES flows. The results show that there is a hypothetical value recognized by society for ES attributable to new GAECs that will be implemented by CAP farmers. In the case study, this value is higher than what farmers currently receive for general environmental purposes through direct payment for the management of arable land. Analysis it could justify that efforts required by the new CAP reform (23-27) to the farmers to achieve sustainable agricultural systems could be compensate and supported by positive citizens valuation.

Targeting DORIS Remission and LLDAS in SLE: A Review.

Remission is the established therapeutic goal for patients with systemic lupus erythematosus (SLE) and is currently defined by the widely adopted Definition Of Remission In SLE (DORIS) criteria. Attainment of remission is rare in the clinical setting, thus an alternative, pragmatic treatment target of low disease activity, as defined by the Lupus Low Disease Activity State (LLDAS), provides a less stringent and more attainable treatment goal for a wider proportion of patients compared with DORIS remission. Randomized controlled trials and real-world analyses have confirmed the positive clinical benefits of achieving either DORIS remission or LLDAS. The treat-to-target (T2T) approach utilizes practical clinical targets to proactively tailor individual treatment regimens. Studies in other chronic inflammatory diseases using the T2T approach demonstrated significantly improved clinical outcomes and quality-of-life measures compared with established standard of care. However, such trials have not yet been performed in patients with SLE. Here we review the evolution of DORIS remission and LLDAS definitions and the evidence supporting the positive clinical outcomes following DORIS remission or LLDAS attainment, before discussing considerations for implementation of these outcome measures as potential T2T objectives. Adoption of DORIS remission and LLDAS treatment goals may result in favorable patient outcomes compared with established standard of care for patients with SLE.

Systemic lupus erythematosus (SLE) is a complex disease that can affect many organs. It can lead to life-threatening complications and poor quality of life. As SLE is very different in each person, it can be challenging to measure disease activity. Doctors are encouraged to set clinical targets to tailor treatment for each patient. Clinical targets include scoring systems that measure disease improvement. Remission is an established clinical target. When a patient is in remission, disease activity is controlled, and the patient does not experience any symptoms. As remission is difficult to achieve, experts developed a more realistic yet still favorable state. This is the lupus low disease activity state, when lupus symptoms are minimal on stable therapy. Doctors use remission and low disease activity in clinical trials to compare existing SLE drugs with new treatments, including biologic drugs. Biologics target key parts of the immune system to help suppress SLE. In this review, we looked at recent clinical trials and found that biologic drugs can help patients achieve remission or low disease activity. Patients who achieved these clinical targets had slower disease progression and improved quality of life. Clinical trials in SLE should continue to use remission and low disease activity targets to help compare treatments. Doctors are encouraged to use them in their routine clinics as treatment targets to measure SLE disease control. Low disease activity state may be particularly helpful as an initial target for patients who are not yet in remission.

Burden of systemic lupus erythematosus in clinical practice: baseline data from the SLE Prospective Observational Cohort Study (SPOCS) by interferon gene signature.

OBJECTIVE: The longitudinal Systemic Lupus Erythematosus Prospective Observational Cohort Study (SPOCS) aims to assess SLE disease course overall and according to type I interferon 4 gene signature (IFNGS). Here, we describe SPOCS patient characteristics by IFNGS and baseline disease activity. METHODS: SPOCS (NCT03189875) is an international study of patients with SLE according to Systemic Lupus International Collaborating Clinics (SLICC)/American College of Rheumatology (ACR) criteria. Enrolled patients from 135 centres in 8 countries were followed biannually for ≤3 years from June 2017 to November 2022. Baseline demographics, disease characteristics, organ system involvement/damage and flares were analysed descriptively according to SLE Disease Activity Index-2000 score (SLEDAI-2K <10/≥10) and IFNGS status (high/low). RESULTS: The study population (n=823) was 93.2% female, with mean (SD) age 45.3 (13.9) years and 11.1 (9.2) years since diagnosis; 52.4% had baseline SLICC/ACR Damage Index score ≥1. Patients with SLEDAI-2K scores ≥10 (241 of 584, 41.3%) vs <10 were younger (mean 42.8 (13.7) vs 46.6 (14.2) years; nominal p=0.001), had shorter SLE duration (10.4 (8.6) vs 12.4 (9.6) years; nominal p=0.012) and more severe flares (12.9% vs 5.3%; nominal p=0.001). IFNGS-high patients (522 of 739, 70.6%) were younger than IFNGS-low patients at first SLE manifestation (30.0 (12.7) vs 36.8 (14.6) years; nominal p<0.001). Proportions of IFNGS-high patients differed according to race (nominal p<0.001), with higher proportions among Asian (83.3%) and black (86.5%) versus white patients (63.5%). Greater proportions of IFNGS-high versus IFNGS-low patients had haematological (12.6% vs 4.1%), immunological (74.4% vs 45.6%) or dermal (69.7% vs 62.2%) involvement. CONCLUSIONS: We identified key characteristics of patients with high disease activity and/or elevated type I IFN signalling, populations with SLE with high unmet needs. Baseline SLEDAI-2K ≥10 was associated with shorter disease duration and more severe flares. IFNGS-high patients were younger at diagnosis and had distinct patterns of organ involvement, compared with IFNGS-low patients.

Novel optimized biopolymer-based nanoparticles for nose-to-brain delivery in the treatment of depressive diseases.

A valid option to bypass the obstacle represented by the blood-brain barrier (BBB) in brain delivery is the use of the unconventional intranasal route of administration. The treatment of depressive diseases, resulting from the depletion of a neurotransmitter in the inter-synaptic space, such as serotonin, is indirectly treated using molecules that can permeate the BBB unlike the latter. In the present article, a set of nanovectors were produced using a mucoadhesive biopolymer, i.e. alginate (Alg). Optimizing the reaction, polymeric nanoparticles having diameter of 30-70 nm were produced, and water stable multi-walled carbon nanotubes functionalized (MWCNT-COOH)/Alg complexes were obtained. These nanovectors were loaded with serotonin, evaluating drug loading/release. By means of Raman microscopy, the cellular internalization of the (MWCNT-COOH)/Alg complex was demonstrated. A complete biocompatibility on neuronal cells was proved for the whole set of nanovectors. Finally, a method of self-administration was tested, which involves the use of a household apparatus, such as an aerosol machine, observing a fine particulate, able to deliver the nanovectors through the nose.

Pro-apoptotic effect of aurothiomalate in prostate cancer cells.

It has been recently demonstrated that small gold compounds could have a potential anti-tumoral activity. Here, we report that aurothiomalate (ATM), a gold compound already used in clinical therapy for the treatment of rheumatoid arthritis, has a pro-apoptotic effect in aggressive prostate cancer (PC3U) cells. In contrast, treatment of human primary epithelial prostate cells (PrEC) with ATM did not cause apoptosis. We demonstrated that ATM is able to disrupt the PKCiota-Par6 complex in PC3U cells and that this disruption leads to the activation of ERK in a dose-dependent manner. Interestingly, we also showed that ERK acts upstream of the activation of caspase 3, leading to apoptosis. ATM treatment also causes activation of p38 and JNK MAP kinases. Moreover we could link ATM treatment to activation of the mitochondrial or so called intrinsic pathway, as we observed release of cytochrome c from mitochondria to cytoplasm, suggesting that the mitochondrial pathway is involved in the pro-apoptotic effect mediated by ATM. Taken together our data suggest that ATM could be a new promising drug for the treatment of advanced prostate cancer.

The type I TGF-beta receptor engages TRAF6 to activate TAK1 in a receptor kinase-independent manner.

Transforming growth factor-beta (TGF-beta) is a multifunctional cytokine that regulates embryonic development and tissue homeostasis; however, aberrations of its activity occur in cancer. TGF-beta signals through its Type II and Type I receptors (TbetaRII and TbetaRI) causing phosphorylation of Smad proteins. TGF-beta-associated kinase 1 (TAK1), a member of the mitogen-activated protein kinase kinase kinase (MAPKKK) family, was originally identified as an effector of TGF-beta-induced p38 activation. However, the molecular mechanisms for its activation are unknown. Here we report that the ubiquitin ligase (E3) TRAF6 interacts with a consensus motif present in TbetaRI. The TbetaRI-TRAF6 interaction is required for TGF-beta-induced autoubiquitylation of TRAF6 and subsequent activation of the TAK1-p38/JNK pathway, which leads to apoptosis. TbetaRI kinase activity is required for activation of the canonical Smad pathway, whereas E3 activity of TRAF6 regulates the activation of TAK1 in a receptor kinase-independent manner. Intriguingly, TGF-beta-induced TRAF6-mediated Lys 63-linked polyubiquitylation of TAK1 Lys 34 correlates with TAK1 activation. Our data show that TGF-beta specifically activates TAK1 through interaction of TbetaRI with TRAF6, whereas activation of Smad2 is not dependent on TRAF6.
