Objectives: The aim of this study is to explore the relationship between ganciclovir exposure and clinical efficacy and/or safety in non-renal solid organ transplant (SOT) recipients receiving preemptive therapy with ganciclovir/valganciclovir and undergoing therapeutic drug monitoring (TDM)-guided dosing optimization.
Methods: Non-renal SOT recipients admitted to IRCCS Azienda Ospedaliero-Universitaria of Bologna receiving preemptive therapy with ganciclovir or valganciclovir for active cytomegalovirus (CMV) infection and who underwent at least one TDM were included. Desired ganciclovir C range was set at 1-3 mg/L, and average ganciclovir trough concentrations (C ) were calculated for each patient.
Although the WHO has declared the end of the pandemic emergency, COVID-19 still poses a threat to immunocompromised patients. The COVID-19 pandemic has spread throughout the world over the last two years, causing a significant number of deaths. After three years, SARS-CoV-2 has lost its initial lethality but has shown a significantly worse prognosis for immunocompromised patients, especially those who have undergone lung transplantation, compared with the general population.

Methods: Solid organ transplant recipients receiving SARS-CoV-2 vaccination were prospectively enrolled (March 2021-January 2022) at six hospitals in Italy and Spain. AbR was assessed at first dose (t), second dose (t), 3 ± 1 month (t), and 1 month after third dose (t).
V-A ECMO during bilateral lung transplantation is routinely used when extracorporeal support is needed, in particular in case of patients affected by pulmonary hypertension. We report the case of a patient successfully transplanted with V-A ECMO assistance using a percutaneous double lumen cannula as venous drainage (Protek Duo, CardiacAssist Inc., Pittsburgh, PA) and central aortic cannulation.

Here, our objective was to assess survival and prognostic factors in lung transplant recipients with IIM-ILD. We retrospectively reviewed data for 64 patients who underwent lung transplantation between 2009 and 2021 at 19 European centers.

Objectives: The aim of this study was to assess the effect of borderline PH (BLPH) on survival in COPD and ILD patients.
Method: Survival was analyzed from retrospective data from 317 patients in 12 centers (Italy, Spain, UK) comparing four hemodynamic groups: the absence of PH (NoPH; mPAP <21 mm Hg or 21-24 mm Hg and PVR <3 WU), BLPH (mPAP 21-24 mm Hg and PVR ≥3 WU), mild-moderate PH (MPH; mPAP 25-35 mm Hg and cardiac index [CI] ≥2 L/min/m2), and severe PH (SPH; mPAP ≥35 mm Hg or mPAP ≥25 mm Hg and CI <2 L/min/m2).
Background: PAP is an ultra-rare respiratory syndrome characterized by the accumulation of surfactant within the alveoli. Whole lung lavage (WLL) is the current standard of care of PAP, however it is not a standardized procedure and the total amount of fluid used to wash each lung is still debated. Considering ICU hospitalization associated risks, a "mini-WLL" with anticipated manual clapping and reduced total infusion volume and has been proposed in our center.

According to various pathogenetic mechanisms and aetiologies, PAP is classified as primary, secondary or congenital. Primary PAP is led by a granulocyte-macrophage colony-stimulating factor (GM-CSF) signalling disruption; the autoimmune form is driven by the presence of anti GM-CSF autoantibodies and represents 90% of all the PAP cases; and the hereditary form is the result of mutations in genes encoding GM-CSF receptor.

Methods: Between January 1, 1992, and August 15, 2017, 463 patients underwent lung transplantation.
Results: We found a total of 19 lung cancers (4.
Background: Malignant pleural mesothelioma (MPM) is an aggressive tumor with poor prognosis, mainly associated with work or environmental exposure to asbestos. MPM's molecular profile is largerly unexplored and effective therapies are still lacking. MPM rarely harbours those somatic genetic lesions that usually characterize solid epithelial-derived tumors.

Paediatric biobanks are an important resource for the development of translational research. At the same time, paediatric biobanks are ethically 'sensitive' due to the unique issues they raise.

However, as minors are a vulnerable population they are also in need of adequate protective measures when they are enrolled in research. Research using biobanked biological samples from children poses additional ethical issues to those raised by research using adult biobanks.

So far, a number of studies have considered a variety of the individual issues crucial to pediatric biobanking such as decision making, privacy protection, minor recontact, and research withdrawal by focusing on theoretical or empirical perspectives. Our research attempted to analyze such issues in a comprehensive manner by exploring practices, rules, and researcher opinions regarding proxy consent, minor assent, specimens and data handling, and return of results as faced in 10 European countries.

Study Design And Methods: Questionnaires were distributed in six maternities. This anonymous and self-completed questionnaire included 29 multiple-choice questions based on: 1) sociodemographic factors, 2) awareness and access to information about cord blood banking, 3) banking option preferences, and 4) donating cord blood units (CBUs) to research.
We analysed knowledge, comprehension, opinions, attitudes and choices related to cord blood donation in seven heterogeneous focus groups including pregnant women, future parents, cord blood donors, midwives and obstetricians/gynaecologists. Comparative evaluations focused on attitudes before versus after delivery and preferences of public versus private banking. The study outlined large support to altruistic cord blood donation and need for better health professionals education in this field.

The facility is based on the model of the Biological Resource Center described by the Organisation for the Economic Cooperation and Development in 1999. This model integrates several critical aspects of collection, characterization, storage and use of biological materials for research purposes and therapeutic applications, thus providing potential advantages of optimizing the use of resources, improving standardization, protecting the rights of both donors and recipients of biological materials, and facilitating international cooperation.
