Acute Kidney Injury in Oncology Patients.

With rapid progress in cancer diagnosis and treatment in the last two decades, outcomes in oncological patients have improved significantly. However, the incidence of acute kidney injury (AKI) in this population has also increased significantly. AKI complicates many aspects of patients' care and adversely affects their prognoses; thus, accurately diagnosing the risk factors for AKI ensures appropriate management. AKI may be caused by pre-renal, intrinsic renal, and post-renal reasons, as well as for combined reasons. This review summarizes the potential etiologies of AKI according to the three

Interventional Cardio-Oncology: Adding a New Dimension to the Cardio-Oncology Field.

The management of cardiovascular disease in patients with active cancer presents a unique challenge in interventional cardiology. Cancer patients often suffer from significant comorbidities such as thrombocytopenia and coagulopathic and/or hypercoagulable states, which complicates invasive evaluation and can specifically be associated with an increased risk for vascular access complications. Furthermore, anticancer therapies cause injury to the vascular endothelium as well as the myocardium. Meanwhile, improvements in diagnosis and treatment of various cancers have contributed to an increase i

A high angiopoietin-2/angiopoietin-1 ratio is associated with a high risk of septic shock in patients with febrile neutropenia.

IntroductionEndothelial barrier breakdown is a hallmark of septic shock, and proteins that physiologically regulate endothelial barrier integrity are emerging as promising biomarkers of septic shock development. Patients with cancer and febrile neutropenia (FN) present a higher risk of sepsis complications, such as septic shock. Nonetheless, these patients are normally excluded or under-represented in sepsis biomarker studies. The aim of our study was to validate the measurement of a panel of microvascular permeability modulators as biomarkers of septic shock development in cancer patients wit

Tumour Cell Size Control and Its Impact on Tumour Cell Function.

Cell size is an important component of cell morphological characteristics. It reflects the characteristics of the cell type, nutritional status, growth stage and physiological function. The cell size of cells of the same type tends to be homogeneous and stable. However, in tumour cells, mutations in cell cycle genes and cytoskeletal genes and overexpression of the corresponding signalling pathways often lead to large variations in tumour cell size. Tumour cells regulate cell size and growth and proliferation through multiple signalling pathways, such as PI3K/Akt/mTOR, Myc and Hippo pathways, w

Osteocytes in the Metastatic Bone Niche: Mechanistic Pathways and Therapeutic Targets.

Osteocytes, once viewed mainly as passive bone-embedded cells, are now recognized as active regulators of the metastatic bone niche. Emerging evidence indicates that these cells integrate mechanical, inflammatory, and tumor-derived cues to influence metastatic seeding, dormancy, reactivation, and lesion progression in bone. This review synthesizes current understanding of osteocyte contributions to skeletal metastasis. We discuss core signaling axes, including osteocyte-derived RANKL/OPG balance, Wnt antagonists (sclerostin/DKK1), mechanotransduction pathways (Piezo1 signaling and connexin-43

Dendritic cell biology and its role in tumor immunotherapy.

As crucial antigen presenting cells, dendritic cells (DCs) play a vital role in tumor immunotherapy. Taking into account the many recent advances in DC biology, we discuss how DCs (1) recognize pathogenic antigens with pattern recognition receptors through specific phagocytosis and through non-specific micropinocytosis, (2) process antigens into small peptides with proper sizes and sequences, and (3) present MHC-peptides to CD4+ and CD8+ T cells to initiate immune responses against invading microbes and aberrant host cells. During anti-tumor immune responses, DC-derived exosomes were discovere

Elucidation of molecular basis of osteolytic bone lesions in advanced multiple myeloma.

Osteolytic bone lesion is a major cause of lower quality of life and poor prognosis in patients with multiple myeloma (MM), but molecular pathogenesis of the osteolytic process in MM remains elusive. Fms-like tyrosine kinase 3 ligand (FLT3L) was reported to be elevated in bone marrow (BM) and blood of patients with advanced MM who often show osteolysis. Here, we investigated a functional link of FLT3L to osteolytic process in MM. We recruited 86, 306, and 52 patients with MM, acute myeloid leukemia (AML), and acute lymphoblastic leukemia (ALL), respectively. FLT3L levels of patients with hemat

Topical Simvastatin Improves Lesions of Diffuse Normolipemic Plane Xanthoma by Inhibiting Foam Cell Pyroptosis.

Xanthoma pathogenesis is speculated to be associated with oxidized low-density lipoprotein (ox-LDL) deposition, although this remains unclear. Most patients with diffuse plane xanthomas present elevated blood lipid levels, and they benefit from treatment with oral lipid-lowering agents. However, there is no available treatment for diffuse normolipemic plane xanthoma (DNPX). In this study, for the first time, we used a topical simvastatin ointment to treat DNPX in three pediatric patients and observed favorable results.

Targeted treatments of bone metastases in patients with lung cancer.

Until now ~30-40% of patients with advanced lung cancer develop bone metastases, but as the newer therapies are extending survival, the chance of developing bone metastases increases. Bone metastases cause skeletal-related events (SREs) such as pathologic fractures, spinal cord compression, radiation therapy or surgery to bone, or hypercalcemia, which can have debilitating consequences affecting patients' health-related quality of life (HR-QOL) and performance status (PS). Poor PS then prevents the patients to receive further lines of treatments, which are available today. SREs are associated
