BCR::ABL1-negative myeloproliferative neoplasms (MPNs) pose a substantial risk of thrombosis, leading to significant morbidity and mortality. Anticoagulant therapy, historically based on vitamin K antagonists (VKAs), has limitations in preventing recurrent thrombotic events and managing bleeding complications. Direct oral anticoagulants (DOACs) offer a potential alternative with improved pharmacokinetics and compliance.

: The Wilms' tumor gene 1 (WT1) plays a critical role in cell development and the regulation of essential genes involved in cell growth and metabolism. In the context of hematopoietic tumors, including acute myeloid leukemia (AML), WT1 has been identified as a potential marker for measurable residual disease (MRD) assessment. Relapse after allogeneic hematopoietic stem cell transplantation (allo-SCT) remains a significant challenge in AML treatment, highlighting the importance of MRD monitoring for risk stratification and treatment decisions.

Background And Aim: Chronic myeloid leukemia (CML) incidence has recently increased in younger individuals. With time, given the nature of the disease and available therapies, as well as the existing paucity and inconsistency of advice, worries about fertility have surfaced. With all these clear unknowns, we designed this study to raise awareness among both physicians and CML patients about whether male and female patients of childbearing age were using contraception at the time of diagnosis, and if so, which methods they were using.

Background: Non-hemolytic acute transfusion reactions (ATRs) are generally not fatal, but they can cause serious increases in workload and costs as a result of blood product wastage.

Methods: A retrospective analysis was made of the data of the 7-year period between January 2016 and December 2022 to identify the possible associations between patient and product characteristics and the development of ATRs.

Results: A total of 113,666 blood products were transfused during the study period.

Article Synopsis
  • Autologous stem cell transplantation (ASCT) is an effective treatment for hematologic cancers, but some patients can't collect enough stem cells with just G-CSF, leading to the use of chemomobilization.
  • In a study of 183 lymphoma and myeloma patients, 43 experienced febrile neutropenia (FN), showing lower preapheresis blood counts and slower platelet and neutrophil recovery post-transplant.
  • Despite the challenges posed by FN, sufficient harvesting of CD34+ stem cells remains possible, indicating the need for prompt treatment of FN and possibly more apheresis sessions.

Introduction: Cyclosporine-A (CsA) and post transplantation cyclophosphamide (PTCy) are common agents used for graft versus host disease (GVHD) prophylaxis in Haploidentical hematopoietic cell transplantation (haplo-HCT). However, the impact of CsA cessation timing in the posttransplant setting on clinical outcomes is uncertain. We aimed to investigate the impact of a novel approach that integrated early CsA cessation with PTCy utilization.

Tissue engineering aims to improve or restore damaged tissues by using scaffolds, cells and bioactive agents. In tissue engineering, one of the most important concepts is the scaffold because it has a key role in keeping up and promoting the growth of the cells. It is also desirable to be able to load these scaffolds with drugs that induce tissue regeneration/formation.

Objective: The objective of this article is to review the efficacy, safety, and evidence for current use and potential future uses of immune-checkpoint inhibitors (ICIs) in the management of resectable non-small cell lung cancer (NSCLC).

Data Sources: A literature review was carried out through PubMed to identify completed and ongoing clinical trials evaluating the use, efficacy, and safety of ICIs in the management of resectable NSCLC.

Data Summary: To date, four phase 3 trials have emerged that have changed our treatment practice concerning the utilization of ICIs during the adjuvant and neoadjuvant settings.

The objective of this study is to generalize the roughness of a fuzzy set-in three-dimensional structure by introducing ternary multiplication. Many results and theorems of rough fuzzy ideals have been extended from semigroup and semiring, to ternary semiring by introducing the definition of a rough fuzzy subset of ternary semiring. By using the concept of set-valued homomorphism and strong set-valued homomorphism, it is proved generalized lower and upper approximations of -fuzzy ideals (semiprime and prime ideals) of ternary semirings are -fuzzy ideals (semiprime and prime ideals) respectively.

Article Synopsis
  • This study investigates the feasibility and success factors of collecting peripheral blood stem cells (PBSC) from healthy donors on the 4th day of mobilization, instead of the usual 5th day, using G-CSF.
  • Data from 141 healthy donors showed that 81.6% had adequate mobilization, with higher CD34+ cell counts linked to successful early collection.
  • The researchers developed a predictive model for clinicians considering early collection, highlighting the importance of donor/recipient weight ratio and CD34+ cell count to maximize success rates.

Cell membrane-derived nanoparticles (NPs) have recently gained popularity due to their desirable features in drug delivery such as mimicking properties of native cells, impeding systemic clearance, and altering foreign body responses. Besides NP technology, adoptive immunotherapy has emerged due to its promise in cancer specificity and therapeutic efficacy. In this research, we developed a biomimetic drug carrier based on chimeric antigen receptor (CAR) transduced T-cell membranes.

Background: Erdheim Chester disease (ECD) is a rare disease with multisystemic involvement in the group of non-langerhans cell histiocytosis. Although nearly 100 years have passed since its definition, the number of cases reported all over the world is below 1000. In addition to the rarity of the disease, low awareness seems to play a role in this.

Purpose: Acromegaly is closely related to increased oxidative stress and endothelial dysfunction (ED). This study aimed to evaluate, for the first time in the literature, signal peptide-CUB-EGF domain-containing protein 1 (SCUBE-1) and endothelial nitric oxide synthase e(NOS) levels in the setting of acromegaly.

Method: A total of 56 acromegaly patients and a control group composed of 30 healthy volunteers were included in this study.

Breast cancer (BC) is the most common heterogeneous disease in women and one of the leading causes of cancer-related death. Surgery, chemotherapy, radiotherapy, hormone, and targeted therapy are the gold standards for BC treatment. One of the significant challenges during the treatment of BC represents resistance to chemotherapeutics, resistance that severely limits the use and effectiveness of the drugs used for BC treatment.

Pes planus, colloquially known as flatfoot, is a deformity defined as the collapse, flattening or loss of the medial longitudinal arch of the foot. The first standard radiographic examination for diagnosing pes planus involves lateral and dorsoplantar weight-bearing radiographs. Recently, many artificial intelligence-based computer-aided diagnosis (CAD) systems and models have been developed for the detection of various diseases from radiological images.

Article Synopsis
  • The study investigates serum levels of kynurenine (KYN) and its metabolites in pregnant women with idiopathic fetal growth restriction (FGR) and oligohydramnios, as KYN is linked to important bodily functions like energy production and immune regulation.
  • Conducted as a case-control study at Ankara City Hospital, it compared pregnant women with FGR and oligohydramnios to low-risk controls, analyzing factors like age, BMI, and serum KYN levels.
  • Results showed significantly lower serum KYN levels in women with FGR and oligohydramnios, especially in those with FGR, indicating that KYN might be crucial in understanding and responding to these pregnancy complications.

Toxoplasmosis is a major health problem and socioeconomic burden, affecting around 30-50% of the global population. Poly(dicarboxylatophenoxy)phosphazene (PCPP) polymer was chosen as adjuvant for the immunogenic peptide antigen. Peptide-loaded PCPP microparticles were synthesized via the coacervation method and the characterization studies of microparticles were conducted to determine their size, charge, morphology, encapsulation efficacy, and loading capacity.
