Competing risk analysis of cardiovascular mortality in multiple myeloma survivors.

BackgroundThe survival of multiple myeloma (MM) patients has significantly improved, and several factors increase the risk of cardiovascular death (CVD) mortality in MM. This study aims to determine the prognostic significance of factors associated with long-term CVD risk in MM survivors.MethodsThe data of MM survivors whose survival time was longer than 36 months were retrieved from the Surveillance, Epidemiology, and End Result (SEER) database between 2000 and 2015. Cox proportional hazards regressions and competing risk survival analyses were utilized to assess the CVD-associated risk facto

Patterns of CMV infection after letermovir withdrawal in recipients of posttransplant cyclophosphamide-based transplant.

Reactivation of latent cytomegalovirus (CMV) is increased in recipients of allogeneic hematopoietic cell transplantation (allo-HCT) with seropositive CMV using posttransplant cyclophosphamide (PT-Cy)-based graft-versus-host disease (GVHD) prophylaxis. Letermovir, a novel DNA terminase complex inhibitor, reduces the incidence of clinically significant CMV infection (csCMVi) in this population; however, parameters that predict csCMVi after letermovir withdrawal are not well described. Here, we examined clinical and immunological parameters in 294 recipients of PT-Cy-based allo-HCT, including 157

Beta-2 microglobulin and all-cause mortality in the era of high-flux hemodialysis: results from the Dialysis Outcomes and Practice Patterns Study.

BackgroundBeta-2 microglobulin (β2M) accumulates in hemodialysis (HD) patients, but its consequences are controversial, particularly in the current era of high-flux dialyzers. High-flux HD treatment improves β2M removal, yet β2M and other middle molecules may still contribute to adverse events. We investigated patient factors associated with serum β2M, evaluated trends in β2M levels and in hospitalizations due to dialysis-related amyloidosis (DRA), and estimated the effect of β2M on mortality.MethodsWe studied European and Japanese participants in the Dialysis Outcomes and Practice Patterns St

Haploidentical transplantation in patients with multiple myeloma making use of natural killer cell alloreactive donors.

Disease relapse is an important problem after allogeneic stem cell transplantations in multiple myeloma (MM). To test the hypothesis that natural killer (NK) cell alloreactivity in the setting of a haploidentical stem cell transplantation (haploSCT) can reduce the risk of myeloma relapse, we performed a small prospective phase 2 study in which we transplanted poor-risk MM patients using a killer cell immunoglobulin-like receptor (KIR)-ligand mismatched haploidentical donor. Patients received bone marrow grafts after reduced-intensity conditioning, with post-transplantation cyclophosphamide (PT

Melphalan flufenamide inhibits osteoclastogenesis by suppressing proliferation of monocytes.

Myeloma bone disease is a major complication in multiple myeloma affecting quality of life and survival. It is characterized by increased activity of osteoclasts, bone resorbing cells. Myeloma microenvironment promotes excessive osteoclastogenesis, a process of production of osteoclasts from their precursors, monocytes. The effects of two anti-myeloma drugs, melphalan flufenamide (melflufen) and melphalan, on the activity and proliferation of osteoclasts and their progenitors, monocytes, were assessed in this study. In line with previous research, differentiation of monocytes was associated wi

Clinical Usefulness of Bronchoalveolar Lavage in the Management of Pulmonary Infiltrates in Adults with Hematological Malignancies and Stem Cell Transplantation.

IntroductionPulmonary complications are frequent in patients with hematologic malignancies and stem cell transplantation. Regardless of the microbiological usefulness of bronchoalveolar lavage (BAL), little information exists on both its benefits as a guide for therapeutic decisions and its impact on patients' clinical outcome.MethodsA prospective observational single-center study was performed between July 2011 and July 2016. Consecutive episodes of pulmonary infiltrates were analyzed in subjects over 18 years of age who presented hematologic malignancies and underwent chemotherapy or stem ce

Effects of dose reduction on bone strength prediction using finite element analysis.

This study aimed to evaluate the effect of dose reduction, by means of tube exposure reduction, on bone strength prediction from finite-element (FE) analysis. Fresh thoracic mid-vertebrae specimens (n = 11) were imaged, using multi-detector computed tomography (MDCT), at different intensities of X-ray tube exposures (80, 150, 220 and 500 mAs). Bone mineral density (BMD) was estimated from the mid-slice of each specimen from MDCT images. Differences in image quality and geometry of each specimen were measured. FE analysis was performed on all specimens to predict fracture load. Paired t-tests w

Cost analysis of skeletal-related events in Spanish patients with bone metastases from solid tumours.

PurposeTo estimate the cost per skeletal-related event (SRE) in patients with bone metastases secondary to solid tumours in the Spanish healthcare setting.MethodsPatients diagnosed with bone metastases secondary to breast, prostate or lung cancer were included in this multicentre, observational study. SREs are defined as pathologic fracture (vertebral and non-vertebral fracture), radiation to bone, spinal cord compression or surgery to bone. Health resource utilisation associated with these events (inpatient stays, outpatient, emergency room and home health visits, nursing home stays and proce

Mapping EORTC QLQ-C30 and QLQ-MY20 to EQ-5D in patients with multiple myeloma.

BACKGROUND: In oncology, health-related quality of life (HRQoL) data are often collected using disease-specific patient questionnaires while generic, patient-level utility data required for health economic modeling are often not collected. METHODS: We developed a mapping algorithm for multiple myeloma that relates HRQoL scores from the European Organization for Research and Treatment of Cancer (EORTC) questionnaires QLQ-C30 and QLQ-MY20 to a utility value from the European QoL-5 Dimensions (EQ-5D) questionnaire. Data were obtained from 154 multiple myeloma patients who had participated in a m

In vitro расширила человека CD4+CD25+ регуляционные T клетки, подавляющие распространение Т клеток.

Регулирующие Т клетки (Tregs) оказались критически важными в балансе между автоиммунизацией и терпимостью и были связаны с несколькими аутоиммунными заболеваниями человека. Однако небольшое число трегов в периферии крови ограничивает их терапевтический потенциал. Поэтому мы разработали протокол, который позволит расширить "Трегз" при сохранении их подавляющей активности. Мы изолировали клетки CD4+CD25 hi от человеческой периферической крови и расширили их in vitro в присутствии anti-CD3 и anti-CD28 Магнитные кситы и высокие концентрации внешнего интерлейкина (IL) -2. Траги были эффективно расш

Cardiac Amyloidosis: Tribulations and New Frontiers.

This review article aims to provide an overview of the pathophysiology, diagnosis, and contemporary management of cardiac amyloidosis (CA) as well as identify the knowledge gaps and areas of potential research. CA can be divided into two main groups: transthyretin cardiac amyloidosis (ATTR-CA) and light chain cardiac amyloidosis (AL-CA). The former further separates into wild-type transthyretin (ATTRwt) and hereditary transthyretin (ATTRv). African Americans, males, and people older than 75 are the most common demographics affected by this disease. Thanks to an increased understanding of this

EZH2 serves as a viable therapeutic target for myeloma-induced osteolytic bone destruction.

Myelomatous bone disease is a complication characterized by lytic bone lesions, reduced bone formation, bone pain, and increased fracture risk. Understanding these underlying mechanisms is crucial for developing effective therapeutic approaches. Here we show the role of enhancer of zeste homolog 2 (EZH2) in bone lesions induced by myeloma cells. Our research reveals that cytokines produced by myeloma-associated adipocytes activate the expression of EZH2 in myeloma cells. Furthermore, we find that EZH2 forms a transcriptional repression complex with transcription factor AP2α. This complex promo

Prominent Role of Histone Modifications in the Regulation of Tumor Metastasis.

Tumor aggressiveness and progression is highly dependent on the process of metastasis, regulated by the coordinated interplay of genetic and epigenetic mechanisms. Metastasis involves several steps of epithelial to mesenchymal transition (EMT), anoikis resistance, intra- and extravasation, and new tissue colonization. EMT is considered as the most critical process allowing cancer cells to switch their epithelial characteristics and acquire mesenchymal properties. Emerging evidence demonstrates that epigenetics mechanisms, DNA methylation, histone modifications, and non-coding RNAs participate
