Cardiotoxicity of immune checkpoint inhibitors.

Cardiac toxicity after conventional antineoplastic drugs (eg, anthracyclines) has historically been a relevant issue. In addition, targeted therapies and biological molecules can also induce cardiotoxicity. Immune checkpoint inhibitors are a novel class of anticancer drugs, distinct from targeted or tumour type-specific therapies. Cancer immunotherapy with immune checkpoint blockers (ie, monoclonal antibodies targeting cytotoxic T lymphocyte-associated antigen 4 (CTLA-4), programmed cell death 1 (PD-1) and its ligand (PD-L1)) has revolutionised the management of a wide variety of malignancies

Targeting Selectins and Their Ligands in Cancer.

Aberrant glycosylation is a hallmark of cancer cells with increased evidence pointing to a role in tumor progression. In particular, aberrant sialylation of glycoproteins and glycolipids has been linked to increased immune cell evasion, drug evasion, drug resistance, tumor invasiveness, and vascular dissemination, leading to metastases. Hypersialylation of cancer cells is largely the result of overexpression of sialyltransferases (STs). Differentially, humans express twenty different STs in a tissue-specific manner, each of which catalyzes the attachment of sialic acids via different glycosidi

Bone cements for percutaneous vertebroplasty and balloon kyphoplasty: Current status and future developments.

Osteoporotic vertebral compression fractures (OVCFs) have gradually evolved into a serious health care problem globally. In order to reduce the morbidity of OVCF patients and improve their life quality, two minimally invasive surgery procedures, vertebroplasty (VP) and balloon kyphoplasty (BKP), have been developed. Both VP and BKP require the injection of bone cement into the vertebrae of patients to stabilize fractured vertebra. As such, bone cement as the filling material plays an essential role in the effectiveness of these treatments. In this review article, we summarize the bone cements

Sympathetic nervous system in tumor progression and metabolic regulation: mechanisms and clinical potential.

Tumor progression is characterized by profound metabolic alterations and dynamic interactions within the tumor microenvironment (TME), which enable rapid proliferation, immunoinvasion, and metastasis. The sympathetic nervous system (SNS), which has been best known for its role in stress regulation, has emerged as a critical regulator of tumor metabolism. The SNS influences glucose, lipid and glutamine metabolism in tumor cells and stromal components by releasing neurotransmitters such as norepinephrine (NE), creating a pro-tumor metabolic and immunosuppressive microenvironment. SNS signaling e

Engagement of Mesenchymal Stromal Cells in the Remodeling of the Bone Marrow Microenvironment in Hematological Cancers.

Mesenchymal stromal cells (MSCs) are a subset of heterogeneous, non-hematopoietic fibroblast-like cells which play important roles in tissue repair, inflammation, and immune modulation. MSCs residing in the bone marrow microenvironment (BMME) functionally interact with hematopoietic stem progenitor cells regulating hematopoiesis. However, MSCs have also emerged in recent years as key regulators of the tumor microenvironment. Indeed, they are now considered active players in the pathophysiology of hematologic malignancies rather than passive bystanders in the hematopoietic microenvironment. Onc

Oncolytic virus therapy in the elderly: immune frailty, challenges, and perspectives.

With global aging accelerating, cancer incidence among older adults is rapidly increasing. Individuals aged ≥65 years now represent 64% of new cancer cases and 71.3% of cancer-related deaths worldwide. This population exhibits a distinct immune imbalance-driven by tumor-induced immunosuppression, immunosenescence, and inflammaging-which contributes to poor tolerance of standard therapies and suboptimal outcomes with PD-1/PD-L1 inhibitors. As an emerging immunotherapeutic strategy, oncolytic viruses (OVs) selectively infect tumor cells, induce immunogenic cell death (ICD), and activate the cGAS

Control of viral infections by epigenetic-targeted therapy.

Epigenetics is defined as the science that studies the modifications of gene expression that are not owed to mutations or changes in the genetic sequence. Recently, strong evidences are pinpointing toward a solid interplay between such epigenetic alterations and the outcome of human cytomegalovirus (HCMV) infection. Guided by the previous possibly promising experimental trials of human immunodeficiency virus (HIV) epigenetic reprogramming, the latter is paving the road toward two major approaches to control viral gene expression or latency. Reactivating HCMV from the latent phase ("shock and k

Global ethylene oxide uses in foods and considerations for food safety.

Ethylene oxide (EtO) is a sterilant widely used for medical devices, but its use is controversial due to its carcinogenicity. In some countries, EtO is also used to fumigate food to eliminate foodborne pathogens, though this practice is banned in others. National regulations on EtO use in food vary widely; exporting countries prioritize trade facilitation and prevention of foodborne illness, while importing countries emphasize maintaining food safety and promoting domestic public health. These divergent public health priorities present challenges to establishing universal maximum residue limit

Cutaneous paraneoplastic syndromes in cats: a comparative clinical review.

PRACTICAL RELEVANCE: Cutaneous paraneoplastic syndromes (CPSs) in cats represent a diverse group of rare dermatological manifestations that occur as indirect consequences of underlying neoplasia. These syndromes are thought to arise due to tumour-associated systemic effects, including dysregulation of immune responses, metabolic disturbances and aberrant production of cytokines or growth factors. Recognising CPSs is clinically relevant, as they may serve as early indicators of occult neoplasia, guiding timely diagnosis and intervention. CLINICAL CHALLENGES: Diagnosing CPSs requires a high ind

This integrative systematic review aimed to identify core competencies for SICs in the context of the Serious Illness Care Program. Methods: Articles published between January 2014 and March 2023 were identified in MEDLINE, PsycINFO, CINAHL, and Pu

A Review of CAR-T Therapy in Pediatric and Young Adult B-Lineage Acute Leukemia: Clinical Perspectives in Singapore.

Approximately 10-15% of pediatric B-cell acute lymphoblastic leukemia (B-ALL) are high risk at diagnosis or relapsed/ refractory. Prior to the availability of chimeric antigen receptor T-cell (CAR-T) in Singapore and the region, the treatment options for these paediatric and young adults are conventional salvage chemotherapy or chemo-immunotherapy regimens as a bridge to allogeneic total body irradiation-based hematopoietic stem cell transplantation (allo-HSCT). This results in significant acute and long-term toxicities, with suboptimal survival outcomes. Finding a curative salvage therapy wit

DESIGN: A qualitative review using directed content analysis of DCNM cases in the Netherlands from 2012 to 2016 published on the RTE website (https://www.euthanasiecommissie.nl/) as of 31 January 2017. RESULTS: Of 33 DCNM cases identified (occurring 2012-2016), 32 case

Ferret coronavirus-associated diseases.

A novel coronavirus of ferrets was first described in 1993. This coronavirus caused an enteric disease called epizootic catarrhal enteritis (ECE). Recently, a ferret systemic coronavirus (FRSCV)-associated disease was discovered. This new systemic disease resembles the dry form of feline infectious peritonitis (FIP) and has been reported in the United States and Europe. This article addresses the clinical signs, pathology, pathogenesis, diagnosis, treatment, and prevention of this ferret FIP-like disease.

Managing anemia in lymphoma and multiple myeloma.

Anemia is common in cancer, and lymphoproliferative disease is no exception. Erythropoiesis-stimulating agents (ESA) have been used for renal anemia since 1986, and considerably later in cancer anemia. The first studies were published around 1993, but the use of ESA did not become common in cancer anemia until in the late 1990s. Cancer anemia is still under-treated. This review gives an overview of the use of ESA in hematologic malignancies. A background is given about this treatment in the cancer field generally. The pathophysiology of cancer anemia is described with special emphasis on the d

Tumor metastasis to bone.

Establishment of skeletal metastasis involves bidirectional interactions between the tumor cell and the cellular elements in the bone microenvironment. A better understanding of the pathophysiology of bone metastasis will be critical in developing the means to prevent bone metastasis or inhibit its progression. The receptor activator of nuclear factor-kappaB (RANK)/RANK ligand pathway has emerged as the key pathway regulating osteolysis in skeletal metastasis. A number of candidate factors, including the Wnt (wingless int) proteins, endothelin-1, and bone morphogenetic proteins, have been impl

The safety and efficacy of the Stryker OptaBlate™ Bone Tumor Ablation system for vertebral body metastases.

BACKGROUND: Metastatic spinal lesions are a significant cause of morbidity and decreased quality of life in those with a high tumor burden. Despite treatment modalities such as medical therapy (e.g., chemotherapy, steroids), spinal augmentation procedures, and radiation therapy, many patients still experience refractory back pain due to neoplastic infiltration of the vertebral body and/or pathologic compression fractures. With the aim to address refractory pain in patients who have exhausted conventional treatment options, Stryker developed the OptablateTM Bone Tumor Ablation system (BTA; Stry

Сопутствующая реанимация острого миелоида лейкемии, связанного с терапией, и ИгГ-МГС во время устного децитабина-седазуридина: доклад по делу.

Фон и клиническая значимость: связь между острой миэлоидной лейкемией (АМЛ) и моноклонной гаммопатией неопределенного значения (МГУС) является редкой и, вероятно, случайной из-за аналогичной эпидемиологии этих двух кровеносных расстройств у пожилых пациентов, которые не имеют права на интенсивную химиотерапию или агрессивное лечение, поскольку они могут быть чрезмерно миэлоспрессивными. Такие методы лечения включают в себя те, которые содержат венетоклакс, легкую для использования разнородную форму децитабина-цедазуридина (DEC-C), которая в настоящее время доступна и утверждена для целей борьб
