In epidemiological research, large datasets are essential to reliably capture small variations among comparative groups or detect new unsuspected associations. Although large databases of web-search information, social media, airline traffic and telephone records are already widely used to capture social trends, large databases in medical research are just emerging. With the universal use of electronic medical records underway, vast amounts of health-related information will become available for biomedical research. Accepting such new research tools-based on the analysis of large pre-existing datasets rather than hypothesis-driven, in-depth prospective study-will require a new mindset in clinical research, as data might be 'messy' and only associations, but not causality, can be detected. In spite of such limitations, the utilization of these new resources for medical research harbours great potential for advancing knowledge about digestive diseases.

Pollen metabarcoding reveals a broad diversity of plant sources available to farmland flower visitors near tropical montane forest.
Front Plant Sci
January 2025
Centro de Investigación en Biodiversidad y Ecología Tropical, Universidad de Costa Rica, San José, Costa Rica.
Despite the widely recognized role of pollinators in ecosystem services, we currently have a poor understanding of the contribution of Natural Protected Areas neighboring agricultural landscapes to crop pollinator diversity and plant-pollinator interactions. Here, we conducted monthly surveys over a period of one year to study the diversity of insect visitors in dominant fruit crops-avocado, plum, apple, and blackberry-and used pollen DNA metabarcoding to characterize the community of plant sources in and around low-intensive farmland bordered by protected montane forest in Costa Rica. We found that crops and native plants had distinct communities of flower visitors, suggesting the presence of fine-scale habitat differences.

Introduction: The role of mast cells (MCs) in clear cell renal carcinoma (ccRCC) is unclear, and comprehensive single-cell studies of ccRCC MCs have not yet been performed.
Methods: To investigate the heterogeneity and effects of MCs in ccRCC, we studied single-cell transcriptomes from four ccRCC patients, integrating both single-cell sequencing and bulk tissue sequencing data from online sequencing databases, followed by validation via spatial transcriptomics and multiplex immunohistochemistry (mIHC).
Results: We identified four MC signature genes (TPSB2, TPSAB1, CPA3, and HPGDS).
Primary cardiac lymphoma: a clinicopathological study of 121 cases.
Front Oncol
January 2025
Department of Hematology, Linyi People's Hospital, Linyi, Shandong, China.
Background: Primary cardiac lymphoma (PCL) is an exceedingly uncommon type of lymphoma that primarily affects the heart and/or pericardium, or manifests through cardiac symptoms due to myocardial infiltration. The infrequency of PCL, coupled with its non-specific clinical presentations, often complicates early diagnosis. This study aims to fill the existing gap in clinical knowledge regarding PCL by detailing a case of PCL and examining its clinical features, auxiliary examinations, treatment approaches, and prognostic outcomes, thereby facilitating early detection and enhancing patient care.

Virus Evol

Institute of Western Agriculture, Chinese Academy of Agricultural Sciences, Changji 831100, China.
Advancements in high-throughput sequencing and associated bioinformatics methods have significantly expanded the RNA virus repertoire, including novel viruses with highly divergent genomes encoding "orphan" proteins that apparently lack homologous sequences. This absence of homologs in routine sequence similarity search complicates their taxonomic classification and raises a fundamental question: Do these orphan viral genomes represent viruses? In 2022, an orphan viral genome encoding a large polyprotein was identified in alfalfa () and thrips (), and named Snake River alfalfa virus (SRAV). SRAV was initially proposed as an uncommon flavi-like virus identified in a plant host distantly related to family .

Front Endocrinol (Lausanne)
January 2025
Department of Oncology, The First Affiliated Hospital of Zhengzhou University, Zhengzhou, China.
Background: In recent years, the incidence of patients with colorectal neuroendocrine neoplasms (CRNENs) has been continuously increasing. When diagnosed, most patients have distant metastases. Liver metastasis (LM) is the most common type of distant metastasis, and the prognosis is poor once it occurs.
