Our analysis revealed a concerning state of affairs, with a prevalence of suboptimal research methodologies and questionable statistical practices. This includes insufficient sample sizes, inadequate model evaluations, lack of necessary reports of model results, etc. In this regard, we present statistical considerations in the development and validation process of numerous models. This will provide the reader with the statistical knowledge related to prediction model necessary to assess bias in studies, compare other published models and determine the clinical utility of models.Summary: Awareness among authors, reviewers and editors of the required statistical considerations is crucial. Reinforcing these in all studies involving prediction models is needed.

Guidelines suggest to use risk assessment tools to guide decisions about thromboprophylaxis, but current tools have modest discriminatory ability. Genetic information from the germline or tumor has the potential to improve VTE prediction. Here, we provide a clinical overview of the current role of genetics in cancer-associated VTE.Recent findings: Germline mutations, such as factor V Leiden and prothrombin G20210A, are associated with a 2- to 2.5-fold increased VTE risk in patients with cancer. Tumor-specific somatic mutations also contribute to VTE risk, such as ALK rearrangements increasing the risk in nonsmall cell lung cancer and IDH1 mutations decreasing the risk in gliomas. Other somatic mutations associated with VTE independent of tumor type include KRAS , STK11 , MET , KEAP1 , CTNNB1 , and CDKN2B . Incorporating data on germline or somatic mutations in risk scores improves discriminatory ability compared with the Khorana score.Summary: Specific germline and somatic mutations are associated with an increased VTE risk in patients with cancer and potentially improve performance of clinical risk scores. The increasing and widespread use of genetic testing in cancer care provides an opportunity for further development of prediction models incorporating genetic predictors.","PeriodicalId":55196,"journal":{"name":"Current Opinion in Hematology","volume":" ","pages":"138-145"},"PeriodicalIF":3.1,"publicationDate":"2025-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11957438/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143034382","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

There are currently no effective treatments for ALI/ARDS, but clinical outcomes could be improved by inhibiting lung injury and/or promoting post-sepsis vascular repair. In this review, we describe studies of endothelial cell metabolic pathways in sepsis-induced ALI/ARDS and vascular repair and identify areas of research that deserve attention in future studies. We also describe studies of metabolic interventions that aim to inhibit ALI/ARDS and/or promote post-sepsis vascular repair, including those that target endothelial cell metabolites, endothelial cell metabolic signaling pathways, and endothelial cell metabolism.Recent findings: Endothelial cells are integral to both the injury and repair phases of ALI/ARDS. During the injury phase of ALI/ARDS, lung endothelial cell survival decreases, and lung endothelial cell-to-endothelial cell (EC-EC) junctions are weakened. During the repair phase after sepsis-induced lung injury, lung endothelial cell proliferation and lung EC-EC junction reannealing occur. These crucial aspects of ALI/ARDS and post-sepsis vascular repair, that is, endothelial cell viability, growth, and junction integrity, are controlled by a myriad of metabolites and metabolic signaling pathways in endothelial cells.Summary: Metabolic signaling pathways in endothelial cells represent a novel class of putative targets for the prevention and treatment of sepsis-induced inflammatory lung injury. Therapies that target metabolic signaling in endothelial cells are currently being explored as potential treatments for sepsis-induced inflammatory lung injury.","PeriodicalId":55196,"journal":{"name":"Current Opinion in Hematology","volume":" ","pages":"157-167"},"PeriodicalIF":3.1,"publicationDate":"2025-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11949724/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142513343","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This includes evaluating current predictive models and identifying potential improvements to enhance clinical decision-making.Recent findings: Cancer patients are at an elevated risk of developing venous thromboembolism (VTE), which significantly impacts mortality and quality of life. Traditional approaches to risk assessment fail to account for the procoagulant changes associated with cancer, making individualized risk prediction a challenge. Current clinical guidelines as per ASCO recommend risk assessment before chemotherapy and endorse thromboprophylaxis as a standard preventive measure. Since any cancer population is highly heterogeneous in terms of VTE risk, predicting the risk of CAT is an oncological challenge. To address this, different predictive models have been developed to stratify patients by risk, enabling targeted thromboprophylaxis. However, these models vary in accuracy and utility. The present review discusses the pros and cons of these different models.Summary: The review examines existing CAT risk prediction models, highlighting their strengths, limitations, and diagnostic performance. It also identifies additional variables that could enhance these models to improve their effectiveness in guiding clinicians toward better risk stratification and treatment decisions for cancer patients.","PeriodicalId":55196,"journal":{"name":"Current Opinion in Hematology","volume":" ","pages":"168-175"},"PeriodicalIF":3.1,"publicationDate":"2025-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11949696/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143383295","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Symptomatic deep vein thrombi are large and exhibit various phases of time-dependent histological changes. Cancer-associated venous thromboemboli contain invasive cancer cells that penetrate the vascular walls, and small cancer cell aggregates are observed within the thrombi. The thrombus composition in atherosclerotic and cardioembolic ischemic strokes varies from case to case, while the thrombi in cancer-associated ischemic stroke are rich in platelets and fibrin. A pathological study on amniotic fluid embolism identified uterine vein thrombi and massive platelet-rich microthrombi in the lungs.Summary: Atherothrombus formation is induced by plaque disruption and may occlude a narrow lumen within a short time. Venous thrombi may grow to a large size in a multistage or chronic manner. Cancer cells can directly contribute to venous thrombus formation. The thrombus formation in amniotic fluid embolism may explain the occurrence of consumptive coagulopathy and cardiopulmonary collapse.","PeriodicalId":55196,"journal":{"name":"Current Opinion in Hematology","volume":" ","pages":"146-156"},"PeriodicalIF":3.1,"publicationDate":"2025-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11957440/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143061502","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, they face challenges related to sample availability and consistent engraftment in mice. New methods, including specialized mouse strains and human tissue scaffolds, have been developed to address these issues. Induced pluripotent stem cells (iPSCs) offer the advantage of indefinite expansion and genetic modification, making them valuable for in vitro research, though protocols to enhance their engraftment in vivo are still being refined.

This review aims to summarize available evidence regarding qualitative and quantitative changes in RBCs in individuals with cancer prior to treatment and in patients undergoing treatment.Recent findings: The most commonly reported changes in RBCs in cancer patients were increased mean corpuscular volume (MCV) and decreased hemoglobin, RBC count, and hematocrit. There were increased lipid peroxidation products and decreased antioxidants. There were increased polyunsaturated fatty acids (PUFAs) and decreased monounsaturated fatty acids (MUFAs) and saturated fatty acids (FAs).
