Neutralizing antibodies to Omicron after the fourth SARS-CoV-2 mRNA vaccine dose in immunocompromised patients highlight the need of additional boosters.

Introduction: Immunocompromised patients have been shown to have an impaired immune response to COVID-19 vaccines.

Methods: Here we compared the B-cell, T-cell and neutralizing antibody response to WT and Omicron BA.2 SARS-CoV-2 virus after the fourth dose of mRNA COVID-19 vaccines in patients with hematological malignancies (HM, n=71), solid tumors (ST, n=39) and immune-rheumatological (IR, n=25) diseases.

Machine-learning prediction model for acute skin toxicity after breast radiation therapy using spectrophotometry.

Purpose: Radiation-induced skin toxicity is a common and distressing side effect of breast radiation therapy (RT). We investigated the use of quantitative spectrophotometric markers as input parameters in supervised machine learning models to develop a predictive model for acute radiation toxicity.

Methods And Materials: One hundred twenty-nine patients treated for adjuvant whole-breast radiotherapy were evaluated.

Safety of third dose of COVID-19 vaccination in frail patients: Results from the prospective Italian VAX4FRAIL study.

Importance: Despite people with impaired immune competence due to an underlying disease or ongoing therapy, hereinafter frail patients, are (likely to be) the first to be vaccinated, they were usually excluded from clinical trials.

Objective: To report adverse reactions of frail patients after receipt of the third dose (booster) administered after completion of a two-dose mRNA vaccination and to compare with those reported after the receipt of the first two doses.

Design: A multicenter, observational, prospective study aimed at evaluating both the safety profile and the immune response of Pfizer-BioNTech or Moderna vaccines in frail patients.

Ovarian tissue cryopreservation and transplantation: 20 years experience in Bologna University.

Objective: To report the 20-year experience in ovarian tissue cryopreservation (OTC) and ovarian tissue transplantation (OTT) of the Bologna clinical center (Bologna, Italy).

Design: Retrospective cohort study.

Patients: 1026 pediatrics and women aged between 2 and 38 years who underwent OTC and OTT between January 2002 to January 2022.

Personalized Automation of Treatment Planning for Linac-Based Stereotactic Body Radiotherapy of Spine Cancer.

Purpose/objectives: Stereotactic ablative body radiotherapy (SBRT) for vertebral metastases is a challenging treatment process. Planning automation has recently reported the potential to improve plan quality and increase planning efficiency. We performed a dosimetric evaluation of the new Personalized engine implemented in Pinnacle3 for full planning automation of SBRT spine treatments in terms of plan quality, treatment efficiency, and delivery accuracy.

Incidence, Risk Factors and Complications of Ocular Graft-Versus-Host Disease Following Hematopoietic Stem Cell Transplantation.

Purpose: The purpose of this research was to evaluate the incidence, risk factors, and complications of ocular graft-versus-host disease (GVHD) in a large single-center study.

Design: Retrospective observational case series.

Methods: This study included 283 patients who underwent hematopoietic stem cell transplantation (HSCT) between 2005 and 2020.
