    The aim of this study was to assess the degree of spermatogenesis defects in sperm analysis in long-term male survivors after allogeneic hematopoietic stem cell transplantation in order to identify the risk factors related to potential infertility after hematopoietic stem cell transplantation and to provide data on longitudinal sperm recovery after hematopoietic stem cell transplantation. Here, the Late Effects Working Party of the European Group for Blood and Marrow Transplantation reports data of sperm analysis from 224 males who underwent hematopoietic stem cell transplantation. Median time between transplantation and sperm analysis was 63 months (8-275 months). At last sperm analysis, presence of any degree of spermatozoa was reported in 70 (31%) and complete azoospermia in 154 (69%) patients. In multivariate analysis, being conditioned with total body irradiation (RR 7.1; 95% CI: 3.4-14.8) and age over 25 years at transplantation (RR 2.4; 95% CI: 1.09-5.2) were significantly associated with higher risk for azoospermia. In patients not conditioned with total body irradiation, ongoing chronic graft-versus-host disease is the main adverse factor for sperm recovery (RR of 3.11; 95% CI: 1.02-9.47; P=0.045). Already established risk factors, such as total body irradiation and age older than 25 years at hematopoietic stem cell transplantation, were seen to be the most relevant adverse risk factor for sperm production after hematopoietic stem cell transplantation. Furthermore, for the first time, ongoing graft-versus-host disease has been shown to be the most relevant adverse factor for sperm recovery, particularly in patients conditioned without total body irradiation. We also introduce a useful scoring system to predict the probability of male long-term survivors' azoospermia.

    BACKGROUND: Literature suggests colonic resection and primary anastomosis (RPA) instead of Hartmann's procedure (HP) for the treatment of left-sided colonic emergencies. We aim to evaluate the surgical options globally used to treat patients with acute left-sided colonic emergencies and the factors that leading to the choice of treatment, comparing HP and RPA.

    METHODS: This is a prospective, international, multicenter, observational study registered on ClinicalTrials.gov. A total 1215 patients with left-sided colonic emergencies who required surgery were included from 204 centers during the period of March 1, 2020, to May 31, 2020. with a 1-year follow-up.

    RESULTS: 564 patients (43.1%) were females. The mean age was 65.9 ± 15.6 years. HP was performed in 697 (57.3%) patients and RPA in 384 (31.6%) cases. Complicated acute diverticulitis was the most common cause of left-sided colonic emergencies (40.2%), followed by colorectal malignancy (36.6%). Severe complications (Clavien-Dindo ≥ 3b) were higher in the HP group (P
