Evolution of Nutritional Status in Patients Undergoing Autologous and Allogeneic Hematopoietic Cell Transplantation or CAR-T Therapy: A Retrospective Observational Study.

Background/objectives: Hematopoietic cell transplantation (HCT) is a curative treatment for various hematological diseases but can lead to complications which increase malnutrition risk, particularly in allogeneic transplantation patients. This study evaluates the nutritional status evolution of patients undergoing HCT during hospitalization and follow-up.

Methods: This retrospective observational study included 365 patients, divided into two groups: 134 underwent allogeneic HCT, while 231 underwent autologous transplantation or CAR-T therapy.

Nutritional Prehabilitation Intervention in Hematological Patients Undergoing Bone Marrow Transplant: A Systematic Review of the Literature.

Background: Nutritional interventions play a critical role in bone marrow transplant (BMT) patients. This review evaluates the effectiveness of nutritional strategies in mitigating post-transplant malnutrition and improving clinical outcomes.

Methods: A systematic review was conducted using PubMed, CINAHL, Cochrane Library, and Embase.

Nutritional Prehabilitation in Patients Undergoing Cystectomy: A Systematic Review.

Background/aim: Nutrition is a key element of the prehabilitation process prior to surgery. The aim of this study was to identify the clinical pathways of nutritional prehabilitation before cystectomy.

Methods: A systematic literature review was conducted in PubMed, the Cochrane Library, CINAHL, Scopus and the Web of Science databases.

Multiplexed Profiling of CDK Kinase Activities in Tumor Biopsies with Fluorescent Peptide Biosensors.

Detection of disease biomarkers constitutes a major challenge for the development of personalized and predictive diagnostics as well as companion assays. Protein kinases (PKs) involved in the coordination of cell cycle progression and proliferation that are hyperactivated in human cancers constitute attractive pharmacological targets and relevant biomarkers. Although it is relatively straightforward to assess the relative abundance of PKs in a biological sample, there is not always a direct correlation with enzymatic activity, which is regulated by several posttranslational mechanisms.

Immune profiles of pre-frail people living with HIV-1: a prospective longitudinal study.

Background: People living with HIV (PLWH) are at risk of frailty, which is predictive for death. As an overactivity of the immune system is thought to fuel frailty, we characterized the immune activation profiles linked to frailty.

Methods: We quantified twenty-seven activation markers in forty-six virological responders (four females and forty-two males; median age, 74 years; median duration of infection, 24 years; median duration of undetectability, 13 years), whose frailty was determined according to the Fried criteria.

Nutritional prehabilitation in head and neck cancer: A systematic review of literature.

Background/scope: Malnutrition is a common problem among patients with head and neck cancer and can have adverse effects on overall health and treatment outcomes. Nutritional and physical prehabilitation are potential strategies to optimize the nutritional status of these patients. This systematic review aimed to identify and describe prehabilitative interventions that can promote an improvement in nutritional status.

Quantitative assessment of mitochondrial morphology relevant for studies on cellular health and environmental toxicity.

Mitochondria are essential organelles that play crucial roles in cellular energy metabolism, calcium signaling and apoptosis. Their importance in tissue homeostasis and stress responses, combined to their ability to transition between various structural and functional states, make them excellent organelles for monitoring cellular health. Quantitative assessment of mitochondrial morphology can therefore provide valuable insights into environmentally-induced cell damage.

Low levels of peripheral blood activated and senescent T cells characterize people with HIV-1-associated neurocognitive disorders.

Background: HIV infection induces a 75% increase in the risk of developing neurocognitive impairment (NCI), which has been linked to immune activation. We therefore looked for immune activation markers correlating with NCI.

Method: Sixty-five people aged 55-70 years living with controlled HIV-1 infection were enrolled in the study and their neurocognitive ability was assessed according to the Frascati criteria.

Low-Bacterial Diet in Cancer Patients: A Systematic Review.

The low-bacterial diet (LBD) is a widely used dietary regimen to reduce the risk of food-borne infections in patients with neutropenic cancer, but its role is controversial due to its unclear benefits. The purpose of this study was to provide an updated analysis of the available evidence on the efficacy of the LBD to reduce the risk of infections, mortality rates, and quality of life (QoL) in neutropenic patients with cancer. A systematic literature search was conducted in the biomedical databases Cochrane Library, PubMed, CINHAL, and EMBASE.

Comparative analysis of transcriptome remodeling in plaque-associated and plaque-distant microglia during amyloid-β pathology progression in mice.

Background: Research in recent years firmly established that microglial cells play an important role in the pathogenesis of Alzheimer's disease (AD). In parallel, a series of studies showed that, under both homeostatic and pathological conditions, microglia are a heterogeneous cell population. In AD, amyloid-β (Aβ) plaque-associated microglia (PAM) display a clearly distinct phenotype compared to plaque-distant microglia (PCM), suggesting that these two microglia subtypes likely differently contribute to disease progression.

Insulin resistance is linked to a specific profile of immune activation in human subjects.

We tested the hypothesis that a particular immune activation profile might be correlated with insulin resistance in a general population. By measuring 43 markers of immune, endothelial, and coagulation activation, we have previously shown that five different immune activation profiles may be distinguished in 150 volunteers. One of these profiles, Profile 2, characterized by CD4+ T cell senescence, inflammation, monocyte, B cell, and endothelial activation, presented elevated insulinemia, glycemia, triglyceridemia, and γ-glutamyl transferase, a marker of liver injury, in comparison with other profiles.

Identification of distinct immune activation profiles in adult humans.

Latent infectious agents, microbial translocation, some metabolites and immune cell subpopulations, as well as senescence modulate the level and quality of activation of our immune system. Here, we tested whether various in vivo immune activation profiles may be distinguished in a general population. We measured 43 markers of immune activation by 8-color flow cytometry and ELISA in 150 adults, and performed a double hierarchical clustering of biomarkers and volunteers.

Ubiquitin and SUMO conjugation as biomarkers of acute myeloid leukemias response to chemotherapies.

Ubiquitin and the ubiquitin-like SUMO are covalently conjugated to thousands of proteins to modulate their function and fate. Many of the enzymes involved in their conjugation are dysregulated in cancers and involved in cancer cell response to therapies. We describe here the identification of biomarkers of the activity of these enzymes and their use to predict acute myeloid leukemias (AML) response to standard chemotherapy (daunorubicin-DNR and cytarabine-Ara-C).

Nonclassical Ligand-Independent Regulation of Go Protein by an Orphan Class C G-Protein-Coupled Receptor.

The orphan G-protein-coupled receptor (GPCR) GPR158 is expressed in the brain, where it is involved in the osteocalcin effect on cognitive processes, and at the periphery, where it may contribute to glaucoma and cancers. GPR158 forms a complex with RGS7-5, leading to the regulation of neighboring GPCR-induced Go protein activity. GPR158 also interacts with o, although no canonical Go coupling has been reported.

Lack of Association for Reported Endocrine Pancreatic Cancer Risk Loci in the PANDoRA Consortium.

Pancreatic neuroendocrine tumors (PNETs) are rare neoplasms for which very little is known about either environmental or genetic risk factors. Only a handful of association studies have been performed so far, suggesting a small number of risk loci. To replicate the best findings, we have selected 16 SNPs suggested in previous studies to be relevant in PNET etiogenesis.
