Sinusoidal Obstruction Syndrome/Veno-Occlusive Disease after Autologous or Allogeneic Hematopoietic Stem Cell Transplantation in Children: A Retrospective Study of the Italian Hematology-Oncology Association–Hematopoietic Stem Cell Transplantation Group

Abstract Sinusoidal obstruction syndrome (SOS), also known as veno-occlusive disease (VOD), is a potentially life-threatening complication that may develop after hematopoietic stem cell transplantation (HSCT). The aims of this retrospective multicenter study were to evaluate the incidence of SOS/VOD in a large cohort of children transplanted in centers across Italy by applying the new European Society for Blood and Marrow Transplantation (EBMT) criteria and to analyze the risk factors underlying this complication. We retrospectively reviewed data of pediatric HSCTs performed in 13 AIEOP (Associazione Italiana di Ematologia e Oncologia Pediatrica)-affiliated centers between January 2000 and April 2016. The new pediatric EBMT criteria were retrospectively applied for diagnoses of SOS/VOD and severity grading. Among 5072 transplants considered at risk for SOS/VOD during the study period, 103 children (2%) developed SOS/VOD, and the grade was severe or very severe in all patients. The median time of SOS/VOD occurrence was 17 days after HSCT (range, 1 to 104). Sixty-nine patients (67%) were treated with defibrotide for a median time of 16 days (range, 4 to 104). In multivariable analysis age P  = .0033), and this difference disappeared 5 years after HSCT. Nonrelapse mortality was significantly higher 1 and 5 years after transplantation in patients who developed SOS/VOD (

The potential role of advanced glycation end products in food allergy pathogenesis

prevalence has dramatically increased in the last two decades. Among dietary factors, it has been hypothesized that advanced glycation endproducts(AGEs), present at high level in junk food, could be involved in FA pathogenesis. AGEs are a heterogeneous group of compounds deriving from sugars(sweets and beverages), autoclaved/processed foods, microwaved foods, more roasted/barbecued meat. To evaluate the AGEs levels in FA children compared with healthy controls and subjects with respiratory allergy. Methods: We evaluated paediatric patients with challenge-proven FA, children with respiratory allergy(RA) and age and sex-matched healthy controls. Subcutaneous AGEs levels were evaluated through the AGE reader. Food-frequency questionnaires were evaluated in all study subjects. In vitro studies were performed on human enterocytes(Caco-2 cells) stimulated with 200 mg/ml of BSA-AGE for 24and48 hours to evaluate effects on gut barrier function: mucin2(mucus production), transpithelial electrical resistance(TEER), ZO-1, occludin expression(intestinal permeability). The direct effects elicited on peripheral blood mononuclear cells (PBMCs) after the treatment with 200 mg/ml of BSA-AGE for 48hours, 4and 7days of treatment were also evaluated. RESULTS: 115 subjects were evaluated and subdivided into 3 groups: group 1 patients with FA (n=31); group 2 patients with RA (n=18), group 3 healthy controls (n=66). The consumption of food containing AGEs was higher in subjects with FA compared to RA children and healthy controls (p<0.05). FA and RA children presented significant higher subcutaneous AGEs levels compared to healthy controls (p<0.05). Linear regression analysis confirmed a significant positive correlation between subcutaneous levels of AGEs and consumption of food containing AGEs. Human enterocytes exposed to BSA-AGE treatment showed a reduction of TEER, of Muc2 and tight junction proteins (Occludin and ZO-1). Moreover, the treatment with BSA-AGE on human PBMCs stimulates pro-inflammatory cytokines TNF-α and Th2 cytokines(IL-5 and IL-13)production , but it was unable to modulate IL-10 production. Finally, after7days of treatment with BSAAGE, we found a low percentage of proliferating CD4+T. CONCLUSIONS: Current hypotheses and models of FA do not adequately explain the dramatic increase observed in the last years

Neuroticism and Conscientiousness Moderate the Effect of Oral Medication Beliefs on Adherence of People with Mental Illness during the Pandemic

Background. After the declaration of the pandemic status in several countries, the continuity of face-to-face visits in psychiatric facilities has been delayed or even interrupted to reduce viral spread. Little is known about the personality factors associated with medication beliefs and adherence amongst individuals with mental illness during the COVID-19 pandemic. This brief report describes a preliminary naturalistic longitudinal study that explored whether the Big Five personality traits prospectively moderate the effects of medication beliefs on changes in adherence during the pandemic for a group of outpatients with psychosis or bipolar disorder. Methods. Thirteen outpatients undergoing routine face-to-face follow-up assessments during the pandemic were included (41 observations overall) and completed the Revised Italian Version of the Ten-Item Personality Inventory, the Beliefs about Medicines Questionnaire, the Morisky Medication Adherence Scale-8-item and the Beck Depression Inventory-II. Results. Participants had stronger concerns about their psychiatric medications rather than beliefs about their necessity, and adherence to medications was generally low. Participants who had more necessity beliefs than concerns had better adherence to medications. People scoring higher in Conscientiousness and Neuroticism traits and more concerned about the medication side effects had poorer adherence. Conclusions. These preliminary data suggest the importance of a careful assessment of the adherence to medications amongst people with psychosis/bipolar disorder during the pandemic. Interventions aimed to improve adherence might focus on patients' medication beliefs and their Conscientiousness and Neuroticism personality traits

How future surgery will benefit from SARS-COV-2-related measures: a SPIGC survey conveying the perspective of Italian surgeons

COVID-19 negatively affected surgical activity, but the potential benefits resulting from adopted measures remain unclear. The aim of this study was to evaluate the change in surgical activity and potential benefit from COVID-19 measures in perspective of Italian surgeons on behalf of SPIGC. A nationwide online survey on surgical practice before, during, and after COVID-19 pandemic was conducted in March-April 2022 (NCT:05323851). Effects of COVID-19 hospital-related measures on surgical patients' management and personal professional development across surgical specialties were explored. Data on demographics, pre-operative/peri-operative/post-operative management, and professional development were collected. Outcomes were matched with the corresponding volume. Four hundred and seventy-three respondents were included in final analysis across 14 surgical specialties. Since SARS-CoV-2 pandemic, application of telematic consultations (4.1% vs. 21.6%; p &lt; 0.0001) and diagnostic evaluations (16.4% vs. 42.2%; p &lt; 0.0001) increased. Elective surgical activities significantly reduced and surgeons opted more frequently for conservative management with a possible indication for elective (26.3% vs. 35.7%; p &lt; 0.0001) or urgent (20.4% vs. 38.5%; p &lt; 0.0001) surgery. All new COVID-related measures are perceived to be maintained in the future. Surgeons' personal education online increased from 12.6% (pre-COVID) to 86.6% (post-COVID; p &lt; 0.0001). Online educational activities are considered a beneficial effect from COVID pandemic (56.4%). COVID-19 had a great impact on surgical specialties, with significant reduction of operation volume. However, some forced changes turned out to be benefits. Isolation measures pushed the use of telemedicine and telemetric devices for outpatient practice and favored communication for educational purposes and surgeon-patient/family communication. From the Italian surgeons' perspective, COVID-related measures will continue to influence future surgical clinical practice

An explainable model of host genetic interactions linked to COVID-19 severity

We employed a multifaceted computational strategy to identify the genetic factors contributing to increased risk of severe COVID-19 infection from a Whole Exome Sequencing (WES) dataset of a cohort of 2000 Italian patients. We coupled a stratified k-fold screening, to rank variants more associated with severity, with the training of multiple supervised classifiers, to predict severity based on screened features. Feature importance analysis from tree-based models allowed us to identify 16 variants with the highest support which, together with age and gender covariates, were found to be most predictive of COVID-19 severity. When tested on a follow-up cohort, our ensemble of models predicted severity with high accuracy (ACC = 81.88%; AUCROC = 96%; MCC = 61.55%). Our model recapitulated a vast literature of emerging molecular mechanisms and genetic factors linked to COVID-19 response and extends previous landmark Genome-Wide Association Studies (GWAS). It revealed a network of interplaying genetic signatures converging on established immune system and inflammatory processes linked to viral infection response. It also identified additional processes cross-talking with immune pathways, such as GPCR signaling, which might offer additional opportunities for therapeutic intervention and patient stratification. Publicly available PheWAS datasets revealed that several variants were significantly associated with phenotypic traits such as "Respiratory or thoracic disease", supporting their link with COVID-19 severity outcome.A multifaceted computational strategy identifies 16 genetic variants contributing to increased risk of severe COVID-19 infection from a Whole Exome Sequencing dataset of a cohort of Italian patients

SARS-CoV-2 susceptibility and COVID-19 disease severity are associated with genetic variants affecting gene expression in a variety of tissues

Variability in SARS-CoV-2 susceptibility and COVID-19 disease severity between individuals is partly due to genetic factors. Here, we identify 4 genomic loci with suggestive associations for SARS-CoV-2 susceptibility and 19 for COVID-19 disease severity. Four of these 23 loci likely have an ethnicity-specific component. Genome-wide association study (GWAS) signals in 11 loci colocalize with expression quantitative trait loci (eQTLs) associated with the expression of 20 genes in 62 tissues/cell types (range: 1:43 tissues/gene), including lung, brain, heart, muscle, and skin as well as the digestive system and immune system. We perform genetic fine mapping to compute 99% credible SNP sets, which identify 10 GWAS loci that have eight or fewer SNPs in the credible set, including three loci with one single likely causal SNP. Our study suggests that the diverse symptoms and disease severity of COVID-19 observed between individuals is associated with variants across the genome, affecting gene expression levels in a wide variety of tissue types

Successful Transplant of a Nonagenarian Liver Graft With Fully Replaced Right Hepatic Artery Reconstruction.

Organ shortage and increasing donor age in liver transplant are stimulating transplant centers to accept otherwise discarded grafts due to donor age or vascular abnormalities; nevertheless, the use of nonagenarian donor grafts is uncommon because advanced age is associated with a higher risk of ischemic-type biliary lesions and worse long-term graft survival. We herein report the case of a 90-year-old donor with fully replaced right hepatic artery. After back-table vascular assessment, the donor right hepatic artery was anastomosed end-to-end with the gastroduodenal artery with 2 polypropylene 8/0 running sutures. Even if the back-table reconstruction of a replaced right hepatic artery is not associated with an enhanced risk of posttransplant vascular complications, vascular abnormalities might discourage the use of otherwise acceptable elderly grafts. The present case underscores that elderly liver grafts should not be discarded per se even in the presence of vascular variants
