Most cases are sporadic, typically presenting at a median age of 18 months, with only 5% occurring after 4 years of age. Clinical presentation often includes an abdominal mass and, less commonly, abdominal pain, weight loss, jaundice and precocious puberty. Low birth weight is a significant risk factor, along with genetic conditions such as Beckwith-Wiedemann syndrome, Simpson-Golabi-Behmel syndrome, familial adenomatous polyposis and trisomy 18. Screening protocols for hepatoblastoma are recommended for children with predisposing conditions. Medical imaging is crucial for hepatoblastoma diagnosis and staging, with abdominal ultrasonography being the initial modality of choice, followed by abdominal contrast MRI for detailed evaluation and monitoring. Chest computer tomography is indicated to evaluate potential lung metastases. The Pretreatment Extent of Disease (PRETEXT) system is employed for hepatoblastoma staging and for guiding treatment strategies such as surgical resection and chemotherapy. Patients with advanced hepatoblastoma may require liver transplantation. Advancements in surgery and chemotherapy have improved survival rates, with 5-year survival rates exceeding 80-90% in localized disease. However, challenges remain in treating individuals with high-risk and metastatic hepatoblastoma. Ongoing research into treatment stratification, the introduction of novel therapies, including targeted and immune therapies, and the application of otoprotectants are essential to address refractory or recurrent hepatoblastoma and to increase the overall survival of patients. Long-term quality of life and the management of treatment-related sequelae are becoming increasingly important as survival rates improve.</p>","PeriodicalId":18910,"journal":{"name":"Nature Reviews Disease Primers","volume":"11 1","pages":"36"},"PeriodicalIF":76.9,"publicationDate":"2025-05-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144128229","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In the past decade, the scientific community has called for the aorta to be viewed as an independent organ, advocating for a holistic approach to understanding thoracic aortic disease, integrating its embryological development, wall composition, pathophysiological mechanisms, surveillance and treatment. Thoracic aortic aneurysm (TAA) is a potentially fatal disease characterized by abnormal dilation of the thoracic aorta, whereby the structural integrity of the vessel wall is compromised. Although epidemiological studies of TAA are confounded by its asymptomatic nature and diagnostic challenges, available evidence suggests that TAA prevalence and treatment outcomes vary according to race, sex and socioeconomic factors. Pathophysiological mechanisms involve interactions between vascular smooth muscle cells and the extracellular matrix, influenced by genetic predisposition and embryological factors as well as arterial hypertension. Diagnosis relies on advanced imaging techniques, with CT angiography considered to be the gold standard diagnostic tool and with genetic screening recommended for heritable conditions. Preventive measures focus on managing cardiovascular risk factors, whereas treatment includes medical management, as well as endovascular and open surgical repair. TAA has a major effect on quality of life, particularly in younger, female and genetically predisposed patients, necessitating further research and tailored interventions.</p>","PeriodicalId":18910,"journal":{"name":"Nature Reviews Disease Primers","volume":"11 1","pages":"34"},"PeriodicalIF":76.9,"publicationDate":"2025-05-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143972391","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Although infection can be asymptomatic, symptomatic disease can vary in severity from mild to severe illness, the latter characterized by icterus and/or multi-organ dysfunction and potentially death. An estimated one million cases of leptospirosis occur globally each year, resulting in ~60,000 deaths. The pathogenesis of severe leptospirosis is poorly understood but is believed to involve an interplay between genetic predisposition, pathogen virulence and dysregulated immune responses that trigger a cytokine storm with associated immunoparesis. Leptospira are susceptible to several low-cost antibiotics, including benzyl penicillin, doxycycline, cephalosporins and macrolides, when used in the early phase of infection. Late disease with organ dysfunction is treated with supportive care, and the benefit of antibiotics during late disease is doubtful. Very few countries have licensed a vaccine for human leptospirosis, and available vaccines only protect against rodent-associated serogroups. Exposure control by behavioural modifications and personal protective measures are the major preventative measures in leptospirosis, and the efficacy of prophylactic antibiotics has not been confirmed in clinical trials. Future research is needed to accurately estimate leptospirosis disease burden across the globe, to understand the pathophysiology of severe leptospirosis to inform the design of targeted immunotherapies and vaccines, and to develop cost-effective and accurate point-of-care diagnostics.</p>","PeriodicalId":18910,"journal":{"name":"Nature Reviews Disease Primers","volume":"11 1","pages":"32"},"PeriodicalIF":76.9,"publicationDate":"2025-05-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144033839","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The disease is divided into cutaneous mastocytosis, systemic mastocytosis (SM) and mast cell sarcoma. SM is further categorized into several non-advanced and advanced forms. The prognosis of cutaneous mastocytosis and non-advanced SM is mostly favourable, whereas prognosis and survival in advanced SM and mast cell sarcoma are poor. During the past 15 years, major advances have been made in the diagnosis, prognosis and management of patients with mast cell neoplasms. Management of mastocytosis consists of symptomatic therapy, including anti-mast cell mediator drugs, and cytoreductive agents for patients with advanced disease and selected individuals with non-advanced disease, as well as recognition and prevention of comorbidities such as osteoporosis and anaphylaxis. The preclinical and clinical development of KIT-D816V-targeting drugs, such as midostaurin or avapritinib, mark a milestone in improving management, the quality of life and survival in patients with SM.
