Supporting Financial Neutrality in Donation of Organs, Cells, and Tissues.

The avoidance of financial gain in the human body is an international ethical standard that underpins efforts to promote equity in donation and transplantation and to avoid the exploitation of vulnerable populations. The avoidance of financial loss due to donation of organs, tissues, and cells is also now recognized as an ethical imperative that fosters equity in donation and transplantation and supports the well-being of donors and their families. Nevertheless, there has been little progress in achieving financial neutrality in donations in most countries.

Toward Equity in Global Access to SoHO-based Therapies: Recommendations for Action.

Therapies derived from substances of human origin (SoHOs) such as organs, cells, and tissues provide life-saving or life-changing treatment for millions of people worldwide each year. However, many people lack timely access to SoHO-based therapies because of insufficient supplies of these exceptional health resources and/or broader barriers in access to healthcare. Despite well-established governmental commitments to promote health equity in general and equity of access to SoHOs in particular, information about inequities in access to most SoHO-based therapies is scarce.

Prevention of Trafficking in Organs, Tissues, and Cells.

Trafficking in human organs, cells, and tissues has long been a source of concern for health authorities and professionals, and several international ethical guidance documents and national laws have affirmed the prohibition of trade in these substances of human origin (SoHOs). However, despite considerable attention to the issue of organ trafficking, this remains a substantial and widespread problem internationally. In contrast, trafficking in cells, tissues, and medical products derived from SoHOs has received comparatively little attention, and the extent and nature of such trafficking remain largely unknown.

From biorepositories to data repositories: Open-access resources accelerate early R&D and validation of equitable diagnostic tools.

Diagnostics are critical tools that guide clinical decision-making for patient care and support disease surveillance. Despite its importance, developers and manufacturers often note that access to specimen panels and essential reagents is one of the key challenges in developing quality diagnostics, particularly in low-resource settings. A recent example, as the COVID-19 pandemic unfolded there was a need for clinical samples across the globe to support the rapid development of diagnostics.

Physical Examination of Potential Deceased Organ and Tissue Donors: An Overview of the European Landscape.

Physical examination (PE) of donors is essential to identify potential risks to the safety and efficacy of donated organs and tissues and is mandatory in the EU. However, no detailed guidance is available as to how PE should be performed. Health authorities (HA) and health professionals (HP) in member states of the European Committee on Organ Transplantation of the Council of Europe (CD-P-TO) and observer countries completed surveys relating to the regulatory requirements for PE and the professional practice of PE in their countries for organ and tissue donors.

THE CEMENTED DOUBLE MOBILITY CUP IN HIP REVISION: DIFFERENT POSSIBILITIES OF USE.

Introduction: The aim of our work is to review those patients who underwent prosthetic hip revision surgery in our hospital considered to be patients at high risk of dislocation or recurrent dislocation, and who underwent a double mobility cemented cup (CMD). Analyzing the different ways to place these cups and the clinical results and reluxations.

Material And Methods: The 69 cases comprised 34 men and 35 women with a mean age of 77,39 years.

A Potential Boron Neutron Capture Therapy Agent Selectively Suppresses High-Grade Glioma: and Exploration.

Glioblastoma (GBM), as the most central nervous system (CNS) intractable disease, has spoiled millions of lives due to its high mortality. Even though several efforts have been made, the existing treatments have had limited success. In this sense, we studied a lead compound, the boron-rich selective epidermal growth factor receptor (EGFR)-inhibitor hybrid , as a potential drug for GBM treatment.

Impact of Plant-Derived Compounds on Amyotrophic Lateral Sclerosis.

Amyotrophic lateral sclerosis (ALS) is a fatal illness characterized by progressive motor neuron degeneration. Conventional therapies for ALS are based on treatment of symptoms, and the disease remains incurable. Molecular mechanisms are unclear, but studies have been pointing to involvement of glia, neuroinflammation, oxidative stress, and glutamate excitotoxicity as a key factor.

PD-1/PD-L1 blockade abrogates a dysfunctional innate-adaptive immune axis in critical β-coronavirus disease.

Severe COVID-19 is associated with hyperinflammation and weak T cell responses against SARS-CoV-2. However, the links between those processes remain partially characterized. Moreover, whether and how therapeutically manipulating T cells may benefit patients are unknown.

The hospital exemption pathway for the approval of advanced therapy medicinal products: an underused opportunity? The case of the CAR-T ARI-0001.

In February 2021, the 'Advanced Therapy Medicinal Product' (ATMP) ARI-0001 (CART19-BE-01), developed at Hospital Clínic de Barcelona (Spain), received authorization from the Spanish Agency of Medicines and Medical Devices (AEMPS) under the 'hospital exemption' (HE) approval pathway for the treatment of patients aged >25 years with relapsed/refractory (RR) acute lymphoblastic leukemia (ALL). The HE pathway foreseen by the European Regulation establishing the legal framework for ATMPs intended to be placed on the market in the EU, allows access to ATMPs prepared on a non-routine basis, according to quality standards, like a custom-made product for an individual patient. Its use is limited to the same Member State where it was developed, in a hospital under the responsibility of a medical practitioner.

Transplantation of Human Induced Pluripotent Stem Cell-Derived Retinal Pigment Epithelium in a Swine Model of Geographic Atrophy.

Background: The aim of this study was to test the feasibility and safety of subretinal transplantation of human induced pluripotent stem cell (hiPSC)-derived retinal pigment epithelium (RPE) cells into the healthy margins and within areas of degenerative retina in a swine model of geographic atrophy (GA).

Methods: Well-delimited selective outer retinal damage was induced by subretinal injection of NaIO into one eye in minipigs ( = 10). Thirty days later, a suspension of hiPSC-derived RPE cells expressing green fluorescent protein was injected into the subretinal space, into the healthy margins, and within areas of degenerative retina.

Is Hospital Exemption an Alternative or a Bridge to European Medicines Agency for Developing Academic Chimeric Antigen Receptor T-Cell in Europe? Our Experience with ARI-0001.

The hospital exemption (HE) allows for the use of advanced therapy medicinal products (ATMPs) next to marketing authorization (MA), but under special conditions. The HE is only applicable to individual patients treated in the hospital setting and it is limited to member states of the European Union (EU); HE is mainly conceded to the academic centers that developed the ATMP, being granted by the national competent authority (NCA), which, in the case of Spain, is the Spanish Agency of Medicines and Medical Devices (AEMPS). The HE follows strict standards of traceability, pharmacovigilance, and quality.

The pathogenic role of c-Kit+ mast cells in the spinal motor neuron-vascular niche in ALS.

Degeneration of motor neurons, glial cell reactivity, and vascular alterations in the CNS are important neuropathological features of amyotrophic lateral sclerosis (ALS). Immune cells trafficking from the blood also infiltrate the affected CNS parenchyma and contribute to neuroinflammation. Mast cells (MCs) are hematopoietic-derived immune cells whose precursors differentiate upon migration into tissues.

Olive oil-derived nitro-fatty acids: protection of mitochondrial function in non-alcoholic fatty liver disease.

Non-alcoholic fatty liver disease (NAFLD) is characterized by excessive liver fat deposition in the absence of significant alcohol intake. Since extra virgin olive oil (EVOO) reduces fat accumulation, we analyzed the involvement of nitro-fatty acids (NO-FA) on the beneficial effects of EVOO consumption on NAFLD. Nitro-fatty acids formation was observed during digestion in mice supplemented with EVOO and nitrite.

Critical pathway for deceased tissue donation: a novel adaptative European systematic approach.

A 'Critical pathway for deceased tissue donation' was developed by the European Committee on Organ Transplantation of the Council of Europe (CD-P-TO) with the aim of providing a common systematic approach to the deceased tissue donation process. Definitions of tissue donors according to the donation stage have been developed so that they can be adapted to different local scenarios. This critical pathway can be used retrospectively to evaluate the potential of tissue donation, assess performance in the tissue donation process and identify areas for improvement.

Passive slow freezing is an efficacious and cost-effective alternative to controlled slow freezing for ovarian tissue cryopreservation.

We aimed to assess the feasibility of passive slow freezing (PSF using Mr. Frosty container, Nalgene) as an alternative to controlled slow rate freezing (CSF using (Freezal™, Air liquide)) for human ovarian tissue (OT) cryopreservation. Validation studies needed were determined after assessing the risk associated (EuroGTP-II ART tool) and were conducted in 66 OT samples from 10 transgender men aged 23.

Sunitinib-Containing Carborane Pharmacophore with the Ability to Inhibit Tyrosine Kinases Receptors FLT3, KIT and PDGFR-β, Exhibits Powerful In Vivo Anti-Glioblastoma Activity.

Malignant gliomas are the most common malignant and aggressive primary brain tumors in adults, the prognosis being-especially for glioblastomas-extremely poor. There are no effective treatments yet. However, tyrosine kinase receptor (TKR) inhibitors and boron neutron capture therapy (BNCT), together, have been proposed as future therapeutic strategies.

A Nitroalkene Benzoic Acid Derivative Targets Reactive Microglia and Prolongs Survival in an Inherited Model of ALS via NF-κB Inhibition.

Motor neuron degeneration and neuroinflammation are the most striking pathological features of amyotrophic lateral sclerosis (ALS). ALS currently has no cure and approved drugs have only a modest clinically therapeutic effect in patients. Drugs targeting different deleterious inflammatory pathways in ALS appear as promising therapeutic alternatives.

CART19-BE-01: A Multicenter Trial of ARI-0001 Cell Therapy in Patients with CD19 Relapsed/Refractory Malignancies.

We evaluated the administration of ARI-0001 cells (chimeric antigen receptor T cells targeting CD19) in adult and pediatric patients with relapsed/refractory CD19 malignancies. Patients received cyclophosphamide and fludarabine followed by ARI-0001 cells at a dose of 0.4-5 × 10 ARI-0001 cells/kg, initially as a single dose and later split into 3 fractions (10%, 30%, and 60%) with full administration depending on the absence of cytokine release syndrome (CRS).

Evaluating risk, safety and efficacy of novel reproductive techniques and therapies through the EuroGTP II risk assessment tool.

Study Question: Can risks associated with novelties in assisted reproduction technologies (ARTs) be assessed in a systematic and structured way?

Summary Answer: An ART-specific risk assessment tool has been developed to assess the risks associated with the development of novelties in ART (EuroGTP II-ART).

What Is Known Already: How to implement new technologies in ART is well-described in the literature. The successive steps should include testing in animal models, executing pre-clinical studies using supernumerary gametes or embryos, prospective clinical trials and finally, short- and long-term follow-up studies on the health of the offspring.

Point-Of-Care CAR T-Cell Production (ARI-0001) Using a Closed Semi-automatic Bioreactor: Experience From an Academic Phase I Clinical Trial.

Development of semi-automated devices that can reduce the hands-on time and standardize the production of clinical-grade CAR T-cells, such as CliniMACS Prodigy from Miltenyi, is key to facilitate the development of CAR T-cell therapies, especially in academic institutions. However, the feasibility of manufacturing CAR T-cell products from heavily pre-treated patients with this system has not been demonstrated yet. Here we report and characterize the production of 28 CAR T-cell products in the context of a phase I clinical trial for CD19+ B-cell malignancies (NCT03144583).

-Carboranyl- and Metallacarboranyl [1,2,3]triazolyl-Decorated Lapatinib-Scaffold for Cancer Therapy Combining Tyrosine Kinase Inhibition and Boron Neutron Capture Therapy.

One of the driving forces of carcinogenesis in humans is the aberrant activation of receptors; consequently, one of the most promising mechanisms for cancer treatment is receptor inhibition by chemotherapy. Although a variety of cancers are initially susceptible to chemotherapy, they eventually develop multi-drug resistance. Anti-tumor agents overcoming resistance and acting through two or more ways offer greater therapeutic benefits over single-mechanism entities.

Banking of corneal stromal lenticules: a risk-analysis assessment with the EuroGTP II interactive tool.

We evaluated the feasibility and performed a risk-benefit analysis of the storage and widespread distribution of stromal lenticules for clinical application using a new systematic tool (European Good Tissue and cells Practices II-EuroGTP II tool), specifically designed for assessing the risk, safety and efficacy of substances of human origin. Three types of potential tissue preparations for human stromal lenticules were evaluated: cryopreserved, dehydrated and decellularized. The tool helps to identify an overall risk score (0-2: negligible; 2-6: low; 6-22: moderate; > 22: high) and suggests risk reduction strategies.
