Background/aim: Cryopreservation of allogeneic hematopoietic cells can be an necessary step in the preparation of a graft for transplantation. The purpose of this study was to evaluate the safety of cryopreservation of allogeneic hematopoietic cells and the clinical outcomes of patients who received a cryopreserved transplant.
Patients And Methods: The study included data from a comparative analysis conducted on a group of 100 patients diagnosed with acute myeloid leukemia who received cryopreserved (50 patients) and fresh (50 patients) transplants. Both quantitative and qualitative parameters of the grafts were evaluated, as well as the patients' hematopoietic recovery.
Results: Statistical analysis of the time to engraftment of neutrophils, nucleated cells, and platelets showed no differences between the group of patients who received cryopreserved transplants and those who received fresh transplants. A higher count of CD34+ cells in the graft significantly reduced the time required for patients to reach their reference values of neutrophils, nuclear cells, and platelets (<0.05).
Conclusion: Cryopreservation of allogenic transplants should be reserved as an option when fresh grafts are not feasible for various reasons.

Background: Global warming has facilitated the spread of mosquito-borne diseases, including dengue, to non-endemic areas like Italy. People living with HIV (PLWH) are at increased risk of severe dengue, especially during secondary infections, but current vaccination options are constrained by safety considerations. This study assesses the seroprevalence of IgG anti-DENV among PLWH in Italy, after the 2023 Italian autochthonous outbreak.

High serum estradiol levels may reduce the success of conception and live birth in both in vitro fertilization and frozen embryo transfer (FET). This retrospective study sought to determine whether an association exists between decreasing the serum estradiol level and the clinical outcome following programmed FET cycles. The analysis retrieved the data of patients who underwent programmed FET cycles at the Center of Reproductive Medicine of Weifang People's Hospital from January 2022 to March 2023.

Objective: This article reports the second live birth in China after frozen-thawed ovarian tissue transplantation to prevent iatrogenic premature ovarian insufficiency (POI).
Method: A patient with aplastic anemia received ovarian tissue cryopreservation before hematopoietic stem cell transplantation, and four ovarian cortex strips were thawed and transplanted into her peritoneal pocket 18 months later.
Results: Pregnancy occurred spontaneously 5 years after grafting, and a healthy girl was born at 39 weeks of gestation.

Objective: Infected femoral artery pseudoaneurysms (IFAPs) are threatening complications of voluntary drug injections in the groin. The purpose of this study is to report the results of open and endovascular repair of IFAPs in intravenous drug abusers.
Methods: The IN-FEMS (INfected Femoral artery psEudoaneurysMs in drug addictS) is a physician-initiated, multicenter and retrospective registry of patients treated for native IFAPs between 2010 and 2023 in 18 different Italian Vascular Surgery Departments.

Background: Gender-affirming treatment for transgender and gender-diverse (TGD) adolescents can consist of puberty suppression (PS) and gender-affirming hormone treatment (GAHT), which may affect fertility.
Aim: This study aims to evaluate the attitudes and decision-making regarding parenthood and fertility preservation from TGD adolescents and their parents and analyze the fertility preservation use and outcome before the start of treatment.
Methods: Adolescents under 18 starting PS or GAHT between November 2021 and March 2024 were enrolled in a multicenter prospective cohort study "ENIGI adolescents," conducted at Amsterdam University Medical Centre, Ghent University Hospital, and Florence University Hospital.
