Hemostatic Abnormalities in Gaucher Disease
Gaucher disease (GD) is an autosomal recessive lysosomal storage disease that is caused by deficiency of the enzyme β-glucocerebrosidase (β-GCase), which is required for the degradation of glycosphingolipids. Deficiency of β-GCase is responsible for the accumulation of glucosylceramide and its deacylated product glucosylsphingosine into lysosomes of reticuloendothelial cells. These lipid-laden cells are known as Gaucher cells. Gaucher cells are large and characterized by eccentric nuclei, condensed chromatin and cytoplasm with heterogeneous “crumpled tissue paper”. The bone marrow, spleen and liver are particularly infiltrated by these cells in GD, leading to the main clinical signs of the disease at diagnosis.

Pediatric Acute Myeloid Leukemia
Pediatric acute myeloid leukemia is a clonal disorder characterized by malignant transformation of the hematopoietic stem cell. The incidence and the outcome remain inferior when compared to pediatric ALL, although prognosis has improved in the last decades, with 80% overall survival rate reported in some studies. The standard therapeutic approach is a combined cytarabine and anthracycline-based regimen followed by consolidation with allogeneic stem cell transplantation (allo-SCT) for high-risk AML and allo-SCT for non-high-risk patients only in second complete remission after relapse.

Steroid Resistance in Pediatric Acute Lymphoblastic Leukemia
Acute lymphoblastic leukemia (ALL) is the most common malignancy among children.  A typical ALL treatment includes three phases: remission induction and consolidation and maintenance, preceded by a prednisone prephase.

Therapy of Relapsed/Refractory Mantle Cell Lymphoma after BTKis
Mantle cell lymphoma (MCL) is a rare mature B-cell non-Hodgkin lymphoma (B-NHL) with historically poor outcomes. Virtually all patients will eventually experience refractory or relapsed (R/R) disease, with a virulent course of resistance and serial relapses, making treatment challenging. The available therapies for R/R MCL are not curative with conventional therapy, their goal being to palliate and prolong survival. A variety of agents approved for R/R MCL, including Bruton’s tyrosine kinase inhibitors (BTKi), changed the treatment landscape of R/R MCL. In the pre-BTKi era, the median progression-free survival (PFS) in R/R disease was 4–9 months. With the introduction of ibrutinib, the median PFS improved to 13–14.6 months. Despite these impressive results, the duration of response is limited, and resistance to BTKi inevitably develops in a subset of patients. Outcomes after progression on BTKi are extremely poor, with a median overall survival (OS) of 6 to 10 months. Certain therapies, such as chimeric antigen receptor (CAR) T cells, have shown promising results after BTKi failure. The preferred combination and sequencing of therapies beyond BTKi remain unestablished.

Factors Associated with Post-Chimeric Antigen Receptor T Cytopenias
Chimeric Antigen Receptor (CAR) T-cell therapy is a promising treatment option for patients suffering from B-cell- and plasma cell-derived hematologic malignancies and is being adapted for the treatment of solid cancers. CAR T is usually associated with cytopenias. These are often biphasic and sometimes prolonged over several months. Cytopenias often lead to infections, need for transfusions of blood products, and increased CAR T morbidity.

Priapism at Diagnosis of Pediatric Chronic Myeloid Leukemia
Pediatric chronic myeloid leukemia (CML) is a very rare malignancy (age-related incidence 0.1/100,000) typically presenting with leucocyte counts >100,000/µL. However, clinical signs of leukostasis are observed at diagnosis in only approximately 10% of all cases and among these, priapism is infrequent.

MiRNA-Based Therapies in NHL
Non-Hodgkin’s lymphoma (NHL) is a very heterogenous group of lymphoid malignancies originating from different stages of B-cell (~90% of the cases) and T-cell or NK-cell differentiation. Increasing evidence has demonstrated the functional roles of miRNAs and lncRNAs in lymphoma onset and progression, either by acting as tumor-promoting ncRNAs or as tumor suppressors, emphasizing their appeal as lymphoma therapeutics. In fact, their intrinsic ability to modulate multiple dysregulated genes and/or signaling pathways makes them an attractive therapeutic approach for a multifactorial pathology like lymphoma.

Extramedullary Relapse of FLT3-ITD Acute Myeloid Leukemia
FMS-like tyrosine kinase 3 (FLT3) is a receptor tyrosine kinase family member. Mutations in FLT3, as well known, represent the most common genomic alteration in acute myeloid leukemia (AML), identified in approximately one-third of newly diagnosed adult patients. In recent years, this has represented an important therapeutic target. Drugs such as midostaurin, gilteritinib, and sorafenib, either alone in association with conventional chemotherapy, play a pivotal role in AML therapy with the mutated FLT3 gene. A current challenge lies in treating forms of AML with extramedullary localization.

Non-Coding RNAs for Leukemia
Early-stage leukemia identification is crucial for effective disease management and leads to an improvement in the survival of leukemia patients. Approaches based on cutting-edge biomarkers with excellent accuracy in body liquids provide patients with the possibility of early diagnosis with high sensitivity and specificity. Non-coding RNAs have received a great deal of interest as possible biomarkers in leukemia due to their participation in crucial oncogenic processes such as proliferation, differentiation, invasion, apoptosis, and their availability in body fluids. Studies have revealed a strong correlation between leukemia and the deregulated non-coding RNAs. On this basis, these RNAs are also great therapeutic targets.

Mutations and Biomarkers of DNA Damage in Myeloma
Multiple myeloma (MM) is a plasma cell malignancy characterized by several genetic abnormalities, including chromosomal translocations, genomic deletions and gains, and point mutations. DNA damage response (DDR) and DNA repair mechanisms are altered in MM to allow for tumor development, progression, and resistance to therapies.

Clinical Approach to Immune Thrombocytopenia
Primary immune thrombocytopenia (ITP) is a complex autoimmune disease whose hallmark is a deregulation of cellular and humoral immunity leading to increased destruction and reduced production of platelets. The heterogeneity of presentation and clinical course hampers personalized approaches for diagnosis and management.

Hypomethylating Agents Failure
Hypomethylating agents (HMA) such as azacitidine and decitabine are a mainstay in the current management of patients with myelodysplastic syndromes/neoplasms (MDS) and acute myeloid leukemia (AML) as either single agents or in multidrug combinations. Resistance to HMA is not uncommon, and it can result due to several tumor cellular adaptations. Several clinical and genomic factors have been identified as predictors of HMA resistance. However, the management of MDS/AML patients after the failure of HMA remains challenging in the absence of standardized guidelines.

Therapeutic Anticoagulation in COVID-19
Thrombotic complications from COVID-19 are now well known and contribute to significant morbidity and mortality. Different variants confer varying risks of thrombotic complications. Heparin has anti-inflammatory and antiviral effects. Due to its non-anticoagulant effects, escalated-dose anticoagulation, especially therapeutic-dose heparin, has been studied for thromboprophylaxis in hospitalized patients with COVID-19.

Blood Transfusion Donor Sex Influences Newborn Outcomes
The risk of both short- and long-term mortality increases with each red blood cell (RBC) transfusion exposure in critically ill patients. In the extremely preterm newborn, one of the most heavily transfused patient groups, observational data has proposed that the association between RBC transfusion and adverse neonatal outcomes may be influenced by donor sex, although the data remains limited.

Geriatric Assessment-Driven Interventions in Older Adults with Cancer
Comprehensive geriatric assessment is defined as a multi-dimensional, multi-disciplinary diagnostic and therapeutic process that is conducted to determine the medical, mental, and functional problems that older people with frailty have so that a coordinated and integrated plan for treatment and follow-up can be developed. Progress has been made in the definition of the best way to detect problems, but the benefits are mostly based on prognosis stratification and on the adaptation of cancer treatment.
