Article Synopsis
  • * A study analyzing 667 bone marrow harvests between 1999 and 2021 found a 13% contamination rate, primarily from common skin bacteria, with male donors showing significantly higher contamination rates (18% vs. 6.8% for females).
  • * The research is notable for being the largest single-center study to explore contamination rates and highlights male donor sex as a key factor, potentially due to differences in skin flora.

Achilles tendinopathy is a disabling condition that affects more than 50% of runners. Pre-clinical studies in a large animal model of naturally-occurring tendinopathy similar to human Achilles tendinopathy has shown benefits of autologous bone marrow-derived mesenchymal stem cell (MSC) implantation. However, MSCs are advanced therapies medicinal products (ATMPs), with strict regulatory requirements.

Disruption of the intestinal microbiome is observed with acute graft-versus-host disease (GVHD) of the lower gastrointestinal (LGI) tract, and fecal microbiota transplantation (FMT) has successfully cured steroid-refractory cases. In this open-label, single-arm, pilot study, third-party, single-donor FMT was administered in combination with systemic corticosteroids to participants with high-risk acute LGI GVHD, with a focus on treatment-naïve cases. Participants were scheduled to receive 1 induction dose (15 capsules per day for 2 consecutive days), followed by 3 weekly maintenance doses, consisting of 15 capsules per dose.

Objectives: Early, accurate diagnosis is crucial for the prognosis of patients with soft tissue sarcomas. To this end, standardization of imaging algorithms, technical requirements, and reporting is therefore a prerequisite. Since the first European Society of Musculoskeletal Radiology (ESSR) consensus in 2015, technical achievements, further insights into specific entities, and the revised WHO-classification (2020) and AJCC staging system (2017) made an update necessary.

BMT CTN 1101 was a Phase III randomized controlled trial comparing reduced-intensity conditioning followed by double unrelated umbilical cord blood transplantation (UCBT) versus HLA-haploidentical related donor bone marrow transplantation (haplo-BMT) for patients with high-risk hematologic malignancies. Here we report the results of a parallel cost-effectiveness analysis of these 2 hematopoietic stem cell transplantation (HCT) techniques. In this study, 368 patients were randomized to unrelated UCBT (n = 186) or haplo-BMT (n = 182).

The Blood and Marrow Transplant Clinical Trials Network study 1101 (BMT CTN 1101; ClinicaTrials.gov identifier NCT01597778) was a multicenter phase III randomized trial comparing the clinical outcomes and quality of life (QoL) of patients with hematologic malignancies undergoing double umbilical cord blood transplantation (dUCBT) or HLA-haploidentical bone marrow transplantation (haplo-BMT) after reduced-intensity conditioning. At a 5-year follow-up, there were no significant differences in progression- free survival (PFS) or overall survival (OS) between the 2 cohorts.

Article Synopsis
  • Close matching of donors and recipients has traditionally been seen as essential for successful allogeneic blood or marrow transplants to minimize complications like graft-versus-host disease (GVHD), yet many patients, particularly from minority groups, struggle to find suitable matches.* -
  • Researchers at Johns Hopkins discovered over 50 years ago that cyclophosphamide could effectively replace total body irradiation in transplant regimens and was successful in animal studies for preventing GVHD.* -
  • High-dose post-transplantation cyclophosphamide (PTCy) has been shown in both animal and human studies to safely reduce GVHD, making it a standard treatment approach even for mismatched transplants, regardless of donor type or other variables.*

Extra-skeletal osteosarcoma is a rare malignant soft tissue sarcoma which can cause a diagnostic challenge due to its non-specific presentation and soft tissue mineralisation, thus potentially mimicking conditions such as myositis ossificans. This review will outline the demographics, clinical presentation, key imaging features, differential diagnosis, management and outcomes of extra-skeletal osteosarcoma and serve as a reference to radiologists and other clinicians involved in the care of patients with soft tissue tumours and tumour-like lesions.

Oncohistones represent compelling evidence for a causative role of epigenetic perturbations in cancer. Giant cell tumours of bone (GCTs) are characterised by a mutated histone H3.3 as the sole genetic driver present in bone-forming osteoprogenitor cells but absent from abnormally large bone-resorbing osteoclasts which represent the hallmark of these neoplasms.

Article Synopsis
  • In a study comparing two types of hematopoietic cell transplantation (dUCB and haplo-BMT), results indicated that both treatments had similar progression-free survival, but haplo-BMT showed lower nonrelapse mortality and better overall survival.
  • A secondary analysis explored how the experience of transplantation centers with these methods affected patient outcomes, categorizing centers based on their prior number of transplants in the year before the study.
  • Findings revealed that haplo-BM centers had significantly lower overall mortality compared to dUCB centers; however, experienced dUCB centers showed no significant difference in mortality compared to haplo-BMT centers, largely due to a higher relapse risk in hap

Proper transitions of care for people with HIV (PWH) are necessary to ensure continuity of care, medication adherence and maintenance of successful clinical outcomes. Three transitions of care may lead to suboptimal outcomes if PWH are not correctly engaged: adolescent to adult, prison to society and the postpartum period. The management of these care transitions is a vital part of engagement in treatment.
