Immune monitoring, immune phenotyping, and precision intervention in severe pneumonia: current evidence and translational challenges

Severe pneumonia remains a major cause of mortality in critically ill patients, with severe community-acquired pneumonia representing a clinically important and representative scenario. This review focuses primarily on severe community-acquired pneumonia as the clinical context, in which outcomes are determined by the interplay between pathogen burden and heterogeneity of host responses. Beyond pathogen-directed therapies, severe pneumonia is frequently characterized by dynamic and partially overlapping states of hyperinflammation, immune dysfunction, and subsequent immunosuppression. Differen

Tissue-Resident Myeloid and Histiocytic Cells in Health and Disease: Novel Emerging Concepts.

Although all myeloid cells are considered to derive from hematopoietic stem cells, the cells in each myeloid lineage are heterogeneous populations, and their distribution and functions vary, depending on underlying physiologic and pathologic processes, age, sex, and genetic and epigenetic signatures. In general, myeloid cells can be separated into circulating and tissue-resident cells. Tissue-resident myeloid cells can further be divided into cells derived from circulating monocytes, circulating stem cells, or local tissue-restricted stem or progenitor cells. Depending on underlying diseases a

A review of mitochondrial dysfunction in diabetic sarcopenia: Mechanisms, diagnosis, and treatment approaches.

Diabetic sarcopenia is a common complication of diabetes, substantially impacting patients' quality of life and prognosis. Its pathogenesis is closely related to energy metabolism, with mitochondria-often referred to as the cellular "powerhouse"-playing a central role in this process. This review focuses on the role of mitochondrial dysfunction in diabetic sarcopenia, emphasizing mechanisms such as energy metabolism imbalance, oxidative stress-induced damage, and abnormalities in mitochondrial biogenesis and dynamics. Additionally, we discussed current research on diagnostic and therapeutic st

The Anti-Cancer Effect of Cinnamon Aqueous Extract: A Focus on Hematological Malignancies.

Cinnamon is an evergreen and tropical plant of the family Lauraceae, growing particularly in Sri Lanka, whose aqueous extract has been tested in different studies to evaluate its possible use as an anti-cancer compound. Both in vitro and in vivo experiments seem to confirm that it acts on various cellular pathways, contributing to down-regulating the activity of molecules that stimulate the proliferation and survival of cells such as the transcription factors NF-KB and AP-1, COX-2, dihydrofolate reductase and pro-angiogenic substances such as VEGF, while up-regulating the function of immune ce

Sepsis in multimorbidity: a domain-based framework for systemic vulnerability and precision care.

Sepsis is a leading cause of morbidity and mortality, amplified by multimorbidity. This narrative review synthesizes epidemiological, pathophysiological, and immunological evidence to show how prevalent conditions-type 2 diabetes and obesity, heart failure and cerebrovascular disease, COPD, chronic kidney disease, cancer/HIV, and severe mental illness-reshape sepsis biology and outcomes. Convergent mechanisms include low-grade inflammation, impaired innate and adaptive immunity, endothelial injury with immunothrombosis/NETosis, barrier disruption with dysbiosis, and neuroendocrine maladaptatio

C-X-C chemokine receptor type 4 (CXCR4) antagonism in precision oncology: Clinical applications and future directions.

Physiologically, the C-X-C chemokine receptor type 4 (CXCR4) signalling pathway regulates key aspects of tumor behavior (growth, metastasis, and immune evasion) and modulates immune system function. Anticancer researchers have identified peptide-based CXCR4 antagonists as promising candidates due to their high targeting specificity and favorable safety profiles. This review provides an analytical examination of CXCR4 antagonistic peptides,the selective Mavorixafor (X4P-001), an advanced, selective CXCR4 inhibitor. When Mavorixafor binds to the same location as C-X-C motif chemokine ligand 12 (

The Relevance of Mass Spectrometry Analysis for Personalized Medicine through Its Successful Application in Cancer "Omics".

Mass spectrometry (MS) is an essential analytical technology on which the emerging omics domains; such as genomics; transcriptomics; proteomics and metabolomics; are based. This quantifiable technique allows for the identification of thousands of proteins from cell culture; bodily fluids or tissue using either global or targeted strategies; or detection of biologically active metabolites in ultra amounts. The routine performance of MS technology in the oncological field provides a better understanding of human diseases in terms of pathophysiology; prevention; diagnosis and treatment; as well a

Imaging of abdominal and pelvic infections in the cancer patient.

Infections are the most commonly encountered complications in patients with cancer. The classical signs and symptoms of infections are often not present in this patient population, which makes the diagnosis more challenging. Host factors play a major role in the development and prognosis of infections in cancer patients; these can be related to the underlying type of malignancy (solid organ versus hematological), tumor burden, anatomic obstruction, altered integrity of barriers (skin or mucosa), treatment-related factors (from chemotherapy, radiation treatment, surgery, interventional procedur

Less is more: inverting the paradigm across the cancer care continuum.

Cancer care often operates under the assumption that 'more is better', resulting in frequent testing, intensive treatments, and constant follow-up. However, this approach has unintended consequences and places significant burdens on patients, providers, and healthcare systems. At the same time, cancer care is evolving rapidly and the number of cancer survivors continues to grow, highlighting the urgent need for reform.In the Netherlands, important efforts are taking place to de-escalate and de-implement ineffective practices across the cancer care continuum, from screening to palliative care.

Secondary Neutropenias.

Neutrophils are a critical component of immunity, particularly against bacteria and other pathogens, but also in inflammation and tissue repair. As a consequence, individuals with neutropenia, defined by a reduction in absolute neutrophil counts, exhibit a strong propensity to severe infections that typically present with muted symptoms. Neutropenias encompass a heterogeneous set of disorders, comprising primary neutropenias, in which specific genes are mutated, and the more common secondary neutropenias, which have diverse non-genetic causes. These include hematological and other cancers, inv

Comprehensive Review of Methodology to Detect Reactive Oxygen Species (ROS) in Mammalian Species and Establish Its Relationship with Antioxidants and Cancer.

Evidence suggests that reactive oxygen species (ROS) mediate tissue homeostasis, cellular signaling, differentiation, and survival. ROS and antioxidants exert both beneficial and harmful effects on cancer. ROS at different concentrations exhibit different functions. This creates necessity to understand the relation between ROS, antioxidants, and cancer, and methods for detection of ROS. This review highlights various sources and types of ROS, their tumorigenic and tumor prevention effects; types of antioxidants, their tumorigenic and tumor prevention effects; and abnormal ROS detoxification in

Molecular mechanisms underlying methotrexate-induced intestinal injury and protective strategies.

Methotrexate (MTX) is a folic acid reductase inhibitor that manages various malignancies as well as immune-mediated inflammatory chronic diseases. Despite being frequently prescribed, MTX's severe multiple toxicities can occasionally limit its therapeutic potential. Intestinal toxicity is a severe adverse effect associated with the administration of MTX, and patients are significantly burdened by MTX-provoked intestinal mucositis. However, the mechanism of such intestinal toxicity is not entirely understood, mechanistic studies demonstrated oxidative stress and inflammatory reactions as key fa
