An individual's T-cell repertoire constantly changes under the influence of external and internal factors. Cells that do not receive a stimulatory signal die, while those that encounter and recognize a pathogen or receive a co-stimulatory signal divide, resulting in clonal expansions. T-cell clones can be traced by monitoring the presence of their unique T-cell receptor (TCR) sequence, which is assembled de novo through a process known as V(D)J rearrangement. Tracking T cells can provide valuable insights into the survival of cells after hematopoietic stem cell transplantation (HSCT) or cancer treatment response and can indicate the induction of protective immunity by vaccination...

Sexual health concerns are one of the most common late effects facing hematopoietic stem cell transplant (HSCT) survivors. The current study tested whether self-reported depression and anxiety symptoms before transplant were associated with embedded items assessing two specific areas of sexual health-sexual interest and sexual satisfaction-one year post-HSCT. Of the 158 study participants, 41% were diagnosed with a plasma cell disorder (n = 60) and most received autologous transplantation (n = 128; 81%)...

BACKGROUND: Hematopoietic cell signal transducer (HCST) and tyrosine kinase-binding protein (TYROBP) are triggering receptors expressed on myeloid cells 2 (TREM2), which are pivotal in the immune response to disease. Despite growing evidence underscoring the significance of TREM2, HCST, and TYROBP in certain forms of tumorigenesis, a comprehensive pan-cancer analysis of these proteins is lacking. METHODS: Multiple databases were synthesized to investigate the relationship between TREM2, HCST, TYROBP, and various cancer types...

PURPOSE: Inborn errors of IFN-γ immunity underlie Mendelian susceptibility to mycobacterial disease (MSMD). Twenty-two genes with products involved in the production of, or response to, IFN-γ and variants of which underlie MSMD have been identified. However, pathogenic variants of IFNG encoding a defective IFN-γ have been described in only two siblings, who both underwent hematopoietic stem cell transplantation (HCST). METHODS: We characterized a new patient with MSMD by genetic, immunological, and clinical means...

Chimerism testing supports the study of engraftment and measurable residual disease (MRD) in patients after allogeneic hematopoietic stem cell transplant. In chimerism MRD, relapse can be predicted by increasing mixed chimerism (IMC), recipient increase ≥0.1% in peripheral blood, and proliferating recipient cells as a surrogate of tumor activity. Conventionally, the combination of short-tandem repeat (STR) and quantitative PCR (qPCR) was needed to ensure assay sensitivity and accuracy in all chimerism status...

OBJECTIVES: To describe late transplant-associated thrombotic microangiopathy (TA-TMA) as chronic endothelial complication in bone marrow (BM) after allogeneic hematopoietic stem cell transplantation (HSCT). METHODS: BM specimens along with conventional diagnostic parameters were assessed in 14 single-institutional patients with late TA-TMA (more than 100 days after HCST), including 11 late with history of early TA-TMA, 10 with early TA-TMA (within 100 days), and 12 non TA-TMA patients...

There is a limited body of evidence for haploidentical hematopoietic stem cell transplantation (haplo-HSCT) in older patients. Previous studies have used a high proportion of bone marrow-derived grafts and a variety of conditioning regimens. In Australia and New Zealand, haplo-HCST is predominantly performed using peripheral blood (PB) with universal use of post-transplantation cyclophosphamide (PTCy). To characterize the outcomes of older recipients undergoing haplo-HSCT for acute myeloid leukemia (AML) and myelodysplastic syndromes (MDS)...

We present the case of a 58-year-old female patient who presented with an extramedullary B-ALL relapse after prior allogenic HSCT and blinatumomab therapy. The patient died from complications of a drug-induced acute liver failure after a salvage therapy combining inotuzumab ozogamicin (InO)-based induction followed by consolidation with high dose MTX and pegaspargase based on the GMALL protocol for older ALL patients. After a diagnosis of the extramedullary relapse in the form of a retro vesical chloroma, the patient received an individualized multi-agent chemotherapy based on induction chemotherapy for older patients in combination with InO...

Sexual and gender minorities (SGMs) have experienced progressive change over the last 50 years. However, this group still reports worse health and health care experiences. An innovative survey instrument that applies stereotype threat to the health care setting, health care stereotype threat (HCST), offers a new avenue to examine these disparities. We harmonized two national probability data sets of SGMs-Generations and TransPop-capturing 503 gay men, 297 lesbians, 467 bisexuals, and 221 trans people...

Sickle cell disease (SCD) is associated with increased risk of neurocognitive deficits. However, whether functioning changes following nonmyeloablative hematopoietic stem cell transplant (HSCT) remains unclear. This study aimed to examine changes in neuropsychological functioning pre- to post-transplant among patients with SCD and compare patients and siblings. Adults with SCD ( n  = 47; M age  = 31.8 ± 8.9) and their sibling stem cell donors ( n  = 22; M age  = 30...

INTRODUCTION: Pancreatic ductal adenocarcinoma (PDAC) is the most prevalent malignancy of the pancreas, and the incidence of this disease is approximately equivalent to the mortality rate. Immunotherapy has made a remarkable breakthrough in numerous cancers, while its efficacy in PDAC remains limited due to the immunosuppressive microenvironment. Immunotherapy efficacy is highly correlated with the abundance of immune cells, particularly cytotoxic T cells. Therefore, molecular classifier is needed to identify relatively hot tumors that may benefit from immunotherapy...

Pure red cell aplasia (PRCA) is a serious complication after ABO-mismatched allogeneic hematopoietic stem cell transplantation (HSCT). Following HSCT, persistent anti-donor isohemagglutinins against donor ABO antigens are considered the immunological cause of PRCA. Patients with post-transplant PRCA are at risk for graft rejection and prolonged red blood cell transfusion dependency. No standard treatment exists. Recently however, the anti-CD38 monoclonal antibody daratumumab has been reported to be an effective treatment for post-transplant PRCA in patients with complete donor chimerism...

BACKGROUND AND AIMS: inflammation plays an important role in atrial fibrillation (AF). In this study, we investigated the significance of immune cell infiltration in AF and identified the potential Hub genes involved in the regulation of immune cell infiltration in AF. METHODS: we obtained AF datasets from the GEO database and analyzed them for obtaining differentially expressed genes (DEGs) by R software. Then, we performed GO, KEGG, and GSEA enrichment analyses of DEGs...

MATERIALS AND METHODS: Single unsalvageable maxillary anterior teeth were replaced with immediate implant placement and provisionalization with definitive abutments in 22 participants. Digital impressions and CBCT images were obtained presurgery, immediately after surgery, and 6 months after surgery...

BACKGROUND: Since 2019, the SARS-CoV-2 pandemic has become a global issue due to its high fatality rate. Over time, the characteristics of the virus have evolved and led to the creation of an omicron strain with higher infectivity but a significantly decreased fatality rate. For patients in urgent need of hematopoietic stem cell transplantation (HSCT), whether the SARS-CoV-2 infection status of donors has a significant impact on HSCT recipients should be clarified. METHODS: To estimate the transplantation risk of SARS-CoV-2-positive donors, 24 patients who underwent HSCT from December 1, 2022 to January 30, 2023 were retrospectively included...

INTRODUCTION: Deficiency of adenosine deaminase 2 (DADA2) is a rare monogenic autoinflammatory disease, whose clinical phenotype was expanded since the first cases, originally described as mimicker of polyarteritis nodosa, with immunodeficiency and early-onset stroke. METHODS: A systematic review according to PRISMA approach, including all articles published before the 31st of August 2021 in Pubmed and EMBASE database was performed. RESULTS: The search identified 90 publications describing 378 unique patients (55...

INTRODUCTION AND HYPOTHESIS: Clinical trials for stress urinary incontinence (SUI) require a robust, reliable, and responsive tool for objective assessment of SUI post-intervention. The Aberdeen Home Continence Stress Test (HCST) is a novel patient-reported objective assessment tool, aimed to be patient-friendly and reduce attrition rates by avoiding hospital appointments and prolonged pad-wearing. We aim to describe the HCST for the first time and evaluate its reliability, diagnostic accuracy, and response to change...

Healthcare stereotype threat (HCST) is defined as "being reduced to group stereotypes within an individual's healthcare encounter," leading to experiences of stigma and discrimination. This current study explores how older gay men living with HIV attribute their healthcare experiences to their social identities. Using HCST as a guiding framework, a content and structural coding analysis was conducted on transcripts from 11 interviews of older gay men living with HIV. The majority of HCST experiences were connected to the social identities of sexual orientation , HIV status , and age...

Relapsed/refractory (rel/ref) acute myeloid leukemia (AML) has a very high mortality rate. At present, hematopoietic stem cell transplantation (HSCT) is the most effective treatment for rel/ref AML. The remission of the primary disease before HSCT is crucial for the transplantation to be effective. Therefore, it is critical to choose a suitable type of chemotherapy before HSCT. Here, we recorded the outcomes of high-throughput drug sensitivity screening (HDS) in children with rel/ref AML. Thirty-seven pediatric rel/ref AML patients who received HDS from September 2017 until July 2021 were analyzed retrospectively...
