Meeting the Shortage of Human Cells and Tissues: The Andalusian Quality Assurance Programme for Tissue Donation.

A quality assurance programme for the tissue donation process was launched in Andalusia in 2020 to facilitate the integration of tissue donation into end-of-life care, and to respond to the growing need for human tissue for therapeutic purposes. The results of this programme are presented here. After identifying the hospital departments in which to intensify the detection of tissue donors, expanding training activities and designing a specific data collection system for possible tissue donors who do not donate their tissues, the results of the donation activity were quantified and the causes of non-donation were analysed by applying the critical pathway for deceased tissue donation methodology.

Validation of a scanning technique with minimal compression for measuring muscle volume with freehand 3D ultrasound.

Freehand 3D ultrasound (3D-US) is a promising technique for measuring muscle volume but it requires gel pads or water tanks to limit probe compression on the skin which makes it hard to use in clinical applications. Our objectives were to measure the effect of different compressions on muscle volume in order to assess the clinical applicability of a minimal compression method for lower limb muscles. 4 muscles of the lower limb on 15 healthy volunteers were scanned with a new commercial freehand 3D-US setup accessible to clinical experimentators.

Evolving deferral criteria for blood donation in France: Plasma donation by men who have sex with men.

Background And Objectives: Since the advent of AIDS, men who have sex with men (MSM) have often been deferred from blood donation. In France, quarantine plasma donation by MSM donors with the same deferral rules as for other donors was introduced in July 2016 and continued up to March 2022. At this time, MSM-specific deferral criteria were lifted for all blood or plasma donation.

Inflammatory markers and auto-Abs to type I IFNs in COVID-19 convalescent plasma cohort study.

Background: COVID-19 convalescent plasma (CCP) contains neutralising anti-SARS-CoV-2 antibodies that may be useful as COVID-19 passive immunotherapy in patients at risk of developing severe disease. Such plasma from convalescent patients may also have additional immune-modulatory properties when transfused to COVID-19 patients.

Methods: CCP (n = 766) was compared to non-convalescent control plasma (n = 166) for soluble inflammatory markers, ex-vivo inflammatory bioactivity on endothelial cells, neutralising auto-Abs to type I IFNs and reported adverse events in the recipients.

[Psychiatry of the elderly: a sometimes complex clinical picture].

Psychiatry of the elderly is a discipline that focuses on the subject as a whole. The interaction of psychiatric, neurological and somatic pathologies impacts the elderly subject on a functional, psychological and social level. Multidisciplinary care is therefore essential to build a complete therapeutic project and to accompany the patient in the plurality of his problems.

Extracorporeal Cardiopulmonary Resuscitation and Survival After Refractory Cardiac Arrest: Is ECPR Beneficial?

The level of evidence of expert recommendations for starting extracorporeal cardiopulmonary resuscitation (ECPR) in refractory out-of-hospital cardiac arrest (OHCA) and in-hospital cardiac arrest (IHCA) is low. Therefore, we reported our experience in the field to identify factors associated with hospital mortality. We conducted a retrospective cohort study of all consecutive patients treated with ECPR for refractory cardiac arrest without return to spontaneous circulation, regardless of cause, at the Caen University Hospital.

[Induced abortions for maternal indications: Retrospective study in Western Normandy between 2010 and 2019].

Introduction: Termination of pregnancy for maternal reasons (MTOP) are authorized in France without limit of term when "the continuation of the pregnancy puts in serious danger the health of the woman". The literature on the subject is rare and we wanted to make an inventory in our region.

Methods: Retrospective observational study between 2010 and 2019 at the multidisciplinary center for prenatal diagnosis in Western Normandy.

Maternal obesity in prolonged pregnancy: Labor, mode of delivery, maternal and fetal outcomes.

Introduction: Obesity is currently not a medical indication for elective induction of labor although obese patients may not be eligible for expectant management after 41 W G. Few data on labor and complications in this population undergoing prolonged pregnancy are known. The objective of our study was to evaluate labor, mode of delivery, maternal and fetal outcomes in prolonged pregnancy in obese patients compared to normal body mass index (BMI).

Promoting the ethical use of safe and effective cell-based products: the Andalusian plan on regenerative medicine.

With regard to regenerative medicine, the expectations generated over the last two decades and the time involved in developing this type of therapies, together with the availability of devices that allow point-of-care treatments through the rapid isolation of cellular or plasma products from patients in the operating theater, represent the perfect breeding ground for the offering of unproven or unregulated therapies on a global scale. A multidisciplinary approach-one based on the collaboration of institutions that, from the perspective of their area of competence, can contribute to reversing this worrying situation-to this problem is essential. It is a priority for local health authorities to take measures that are adapted to the particular situation and regulatory framework of their respective territory.

Trends in platelet distributions from 2008 to 2017: a survey of twelve national and regional blood collectors.

Background: This multi-national study evaluated changes in platelet (PLT) unit distributions at 12 national or regional blood collectors over a 10-year period.

Methods: Data on the total number of PLT distributions, the collection method, that is apheresis vs whole blood-derived (WBD), the PLT unit characteristics and post-collection modifications were obtained from 12 national or regional blood collectors from 2008 through 2017. Individual WBD PLT units were converted to apheresis equivalent units (i.

[The regenerative medicine and stem cell business: confusion with legal implications].

The rise of regenerative medicine and the growth of the offer of autologous therapies, obtained from blood, cells or tissues of the patients, have been favoured by the current availability of an increasing number of commercial devices. Most of these devices are easy to use, allowing the elaboration of products and its application within the same procedure. Regardless of the questionable efficacy and safety of many of the treatments offered under the claim of stem cells or regenerative medicine, most of the centres and professionals offering these treatments are unaware of the legal requirements and implications of their use.

Hospitals have to deal strong with economic constraints and increasing requirements in terms of quality and safety of care. To address these constraints, one solution could be the adoption of approaches from the industry sector. Following the decree of April 6, 2011 on the quality management of the medication use process, some of these approaches, such as risk management, are now part of the everyday work of healthcare professionals.

Nanoimmunoassay onto a screen printed electrode for HER2 breast cancer biomarker determination.

A chip format sandwich-type immunoassay based on Nanobodies(®) (Nbs) with the Human Epidermal Growth Factor Receptor (HER2) extracellular domain as antigen model has been developed. The HER2 is considered as an important biomarker because its overexpression causes an aggressive type of breast cancer. Nbs are single domain antigen-binding fragments derived from camelid heavy-chain antibodies.

High-resolution structure of a papaya plant-defense barwin-like protein solved by in-house sulfur-SAD phasing.

The first crystal structure of a barwin-like protein, named carwin, has been determined at high resolution by single-wavelength anomalous diffraction (SAD) phasing using the six intrinsic S atoms present in the protein. The barwin-like protein was purified from Carica papaya latex and crystallized in the orthorhombic space group P212121. Using in-house Cu Kα X-ray radiation, 16 cumulative diffraction data sets were acquired to increase the signal-to-noise level and thereby the anomalous scattering signal.
