TP53 Mutant Acute Myeloid Leukemia
TP53 mutated/deleted acute myeloid leukemia (AML) stands out as one of the poorest prognosis forms of acute leukemia with a median overall survival not reaching one year in most cases, even in selected cases when allogenic stem-cell transplantation is performed. This aggressive behavior relies on intrinsic chemoresistance of blast cells and on high rates of relapse.

ABCG2 in Acute Myeloid Leukemia
ABCG2 is an efflux transporter responsible for inducing multidrug resistance (MDR) in leukemic cells; through its ability to extrude many antineoplastic drugs, it leads to AML resistance and/or relapse. Moreover, ABCG2 may be co-expressed with other MDR-related proteins and is finely regulated by epigenetic mechanisms.

Acquired Isolated Factor VII Deficiency in Plasma Cell
Acquired isolated factor VII (FVII) deficiency is a rare but important discovery in patients with plasma cell disorders with significant therapeutic and prognostic implications. The discovery of acquired FVII deficiency in a patient with multiple myeloma (MM) or monoclonal gammopathy of uncertain significance (MGUS) should prompt an evaluation for AL amyloidosis, particularly for amyloid hepatosplenic involvement, whenever not previously documented. Acquired FVII deficiency in patients with MM and AL amyloidosis is frequently associated with severe bleeding diathesis, also related to a number of concomitant predisposing factors, adversely affecting the outcome. The prompt institution of a rapidly acting therapy is crucial to prevent severe bleeding complications and positively impact outcome. Recombinant activated factor VII (rVIIa) may represent a useful supportive care measure, both in treating active bleeding and in the peri-procedural setting. However, further clinical experience is needed to optimize the therapeutic management of this rare disorder.

Acute Hematologic Malignancy-Associated ARDS
Acute hematologic malignancies are a group of heterogeneous blood diseases with a high mortality rate, mostly due to acute respiratory failure (ARF). Acute respiratory distress syndrome (ARDS) is one form of ARF which represents a challenging clinical condition.

Acute Lymphoblastic Leukemia Immunotherapy Treatment
Acute lymphoblastic leukemia (ALL) is a blood cancer that primarily affects children but also adults. It is due to the malignant proliferation of lymphoid precursor cells that invade the bone marrow and can spread to extramedullary sites. ALL is divided into B cell (85%) and T cell lineages (10 to 15%); rare cases are associated with the natural killer (NK) cell lineage (<1%). To date, the survival rate in children with ALL is excellent while in adults continues to be poor. Despite the therapeutic progress, there are subsets of patients that still have high relapse rates after chemotherapy or hematopoietic stem cell transplantation (HSCT) and an unsatisfactory cure rate. Hence, the identification of more effective and safer therapy choices represents a primary issue.

Acute Myeloid Leukemia for Elders
Acute myeloid leukemia (AML) is an aggressive hematologic malignancy affecting about 0.5% of people in their lifetime. Over the last few decades, a growing understanding of AML has revealed it to be a heterogenous disease with a widely variable prognosis. This is largely driven by disease biology, the ability to tolerate highly toxic multi-agent chemotherapy and, in most cases, undergo allogeneic stem cell transplantation to be cured of disease.

Adult Post-Transplant Lymphoproliferative Disorder
Post-transplant lymphoproliferative disorder (PTLD) is a rare but severe complication of hematopoietic or solid organ transplant recipients, with variable incidence and timing of occurrence depending on different patient-, therapy-, and transplant-related factors. The pathogenesis of PTLD is complex, with most cases of early PLTD having a strong association with Epstein–Barr virus (EBV) infection and the iatrogenic, immunosuppression-related decrease in T-cell immune surveillance. Without appropriate T-cell response, EBV-infected B cells persist and proliferate, resulting in malignant transformation. Classification is based on the histologic subtype and ranges from nondestructive hyperplasias to monoclonal aggressive lymphomas, with the most common subtype being diffuse large B-cell lymphoma-like PTLD. Management focuses on prevention of PTLD development, as well as therapy for active disease. Treatment is largely based on the histologic subtype.

Advancements and Considerations in HSCT for CML
Hematopoietic stem cell transplantation (HSCT) for chronic myeloid leukemia (CML) patients has transitioned from the standard of care to a treatment option limited to those with unsatisfactory tyrosine kinase inhibitor (TKI) responses and advanced disease stages. In recent years, the threshold for undergoing HSCT has increased. Most CML patients now have life expectancies comparable to the general population, and therefore, the goal of therapy is shifting toward achieving treatment-free remission (TFR). While TKI discontinuation trials in CML show potential for achieving TFR, relapse risk is high, affirming allogeneic HSCT as the sole curative treatment. HSCT should be incorporated into treatment algorithms from the time of diagnosis and, in some patients, evaluated as soon as possible.

Aging of Human Hematopoietic Stem and Progenitor Cells
In human blood and immune system, aging is characterized by a decline of innate immunity and regenerative potential of hematopoietic stem cells. This decline is defined at a molecular level in the  hematopoietic stem and progenitor cells (HSPC) compartment. A series of studies have demonstrated that aging of HSPC is induced by an accumulation of senescent cells in the HSPC compartment of the aging human bone marrow. Multi-omics studies have provided evidence that senescent cells are characterized by elevated central carbon metabolism. This property has rendered an enrichment of senescent HSPC for in depth mechanistic studies possible, and in addition has provided novel targets for senolysis therapy strategies.

Alarmins in Pathogenesis and Progression of Multiple Myeloma
Multiple Myeloma (MM) is a haematological disease resulting from the neoplastic transformation of plasma cells. The uncontrolled growth of plasma cells in the bone marrow and the delivery of several cytokines causes bone erosion that often does not regress, even in the event of disease remission. MM is characterised by a multi-step evolutionary path, which starts with an early asymptomatic stage defined as monoclonal gammopathy of undetermined significance (MGUS) evolving to overt disease.
