Improving predictive accuracy of early recurrence in pancreatic ductal adenocarcinoma: Role of postoperative serum tumor markers.

In a recent study by He , the nomogram integrates postoperative serum tumor markers such as carbohydrate antigen 19-9 and carcinoembryonic antigen, thereby improving the accuracy of identifying high-risk patients compared to relying solely on preoperative markers, which has significant implications for customizing adjuvant therapy and potentially improving outcomes for this aggressive form of cancer. However, the study's single-center design and short follow-up period may limit the generalizability of its findings and potentially introduce reporting bias. Future studies could consider additional confounding factors, such as adjuvant chemotherapy and variations in surgical techniques, to improve the model's accuracy.

How do we measure the costs, benefits, and harms of sharing data from biomedical studies? A protocol for a scoping review.

Introduction: The benefits of sharing participant-level data, including clinical or epidemiological data, genomic data, high-dimensional imaging data, or human-derived samples, from biomedical studies have been widely touted and may be taken for granted. As investments in data sharing and reuse efforts continue to grow, understanding the cost and positive and negative effects of data sharing for research participants, the general public, individual researchers, research and development, clinical practice, and public health is of growing importance. In this scoping review, we will identify and summarize existing evidence on the positive and negative impacts and costs of data sharing and how they are measured.

Proton pump inhibitors and all-cause mortality risk among cancer patients.

Background: Proton pump inhibitors (PPIs) are widely used, including among cancer patients, to manage gastroesophageal reflux and other gastric acid-related disorders. Recent evidence suggests associations between long-term PPI use and higher risks for various adverse health outcomes, including greater mortality.

Aim: To investigate the association between PPI use and all-cause mortality among cancer patients by a comprehensive analysis after adjustment for various confounders and a robust methodological approach to minimize bias.

Noninvasive in vivo imaging of macrophages: understanding tumor microenvironments and delivery of therapeutics.

Macrophages are pivotal in the body's defense and response to inflammation. They are present in significant numbers and are widely implicated in various diseases, including cancer. While molecular and histological techniques have advanced our understanding of macrophage biology, their precise function within the cancerous microenvironments remains underexplored.

Integration of 168,000 samples reveals global patterns of the human gut microbiome.

The factors shaping human microbiome variation are a major focus of biomedical research. While other fields have used large sequencing compendia to extract insights requiring otherwise impractical sample sizes, the microbiome field has lacked a comparably sized resource for the 16S rRNA gene amplicon sequencing commonly used to quantify microbiome composition. To address this gap, we processed 168,464 publicly available human gut microbiome samples with a uniform pipeline.
