Objective: To describe the recalled medical history, clinical manifestations, and treatment of yaws and syphilis by syphilis seroreactive blood donors in Kumasi, Ghana.
Methods: Of the blood donors at Komfo Anokye Teaching Hospital, Kumasi, Ghana tested with the syphilis rapid diagnostic test (RDT) and later by rapid plasma reagin (RPR) test, 526 were seroreactive. Four hundred and seventy-one (89.5%) of these subjects were confirmed with the Ortho-Vitros Syphilis TP test as the gold standard and were interviewed to determine past or present clinical manifestations of yaws and syphilis.
Results: Of the 471 respondent donors, 28 (5.9%) gave a history of skin lesions and sores; four (14.3%) of these subjects, who were all male and RPR-positive, recalled a diagnosis of syphilis. All four reported having had skin lesions/bumps with slow-healing sores, but only one of them had had these symptoms before the age of 15 years.
Conclusions: A small proportion of confirmed seroreactive donors in this sample had any recall of symptoms or treatment for yaws or syphilis. These data suggest that clinical questioning adds little further information to the current screening algorithm. The relative contribution of yaws and syphilis to frequent positive tests in endemic areas remains speculative.

The immune checkpoint receptors play a crucial role in managing the transplantation outcome including development of acute graft versus host disease (aGVHD) and disease recurrence following allogeneic hematopoietic stem cell transplantation (allo-HSCT) is well established. This study aimed to investigate the expression of immune checkpoint receptors, including PD-1/PD-L1, CTLA-4, TIM-3, and LAG-3 in donors, as well as changes in their expression during the first 90 days (day 30 and day 90) post-HLA-matched allo-HSCT, concerning the development of aGVHD and disease relapse. Forty-one donor/recipient pairs were included in this study.

Variant D antigens can cause variable serologic results when typing with Anti-D reagents. There is limited information regarding the ability of Anti-D reagents to differentiate between D variants defined by genotyping. This study was performed to determine if a panel of 20 U.

Red blood cell (RBC) alloimmunization can occur because of exposure to various sensitizing factors and poses a constant threat in transfusion. Assisted reproductive technology (ART) involves manipulation of sperm, ova, or embryos with the goal of producing a pregnancy. We present an interesting case of ART-induced maternal alloimmunization (AIMA) due to anti-c in a woman carrying a twin pregnancy.

Corneal graft (keratoplasty) is the most common allograft in the world, but the imbalance between the number of donors and the number of patients waiting for transplants is abysmal on a global scale and varies enormously from one country to another. The risk of transmission of systemic diseases from donor to recipient is demonstrably low. In over 50 years and an estimated 2.

Although post-transplant cyclophosphamide (PTCY)-based prophylaxis has become a widely adopted strategy for preventing graft-versus-host disease (GVHD) in 9 out of 10 HLA-mismatched unrelated donors (MMUDs), allogeneic hematopoietic cell transplants (allo-HCTs), data on the safety and efficacy of PTCY in this setting remain limited. This single-center study investigates the outcomes of 94 adults with hematological malignancies undergoing MMUD allo-HCT with PTCY and tacrolimus (Tac) (PTCY-Tac) between 2014 and 2023. The median age was 53 years, and 60.
