Abstract

BACKGROUND: Rheumatoid arthritis (RA) and calcium pyrophosphate deposition (CPPD) disease are forms of inflammatory arthritis which may have similar presentations. There is growing recognition that these conditions can coexist, especially in elderly patients. This systematic literature review aims to examine the epidemiology and clinical characteristics of patients with both RA and CPPD disease. METHODS: A systematic literature search was performed from database inception to 31st January 2026 using the databases EMBASE, MEDLINE, Scopus, PubMed, CINAHL, and Cochrane. Keywords relating to RA, CPPD and chondrocalcinosis were used. Inclusion criteria were studies published in English and those that addressed the co-occurrence of RA and CPPD. RESULTS: The search yielded 24 studies comprising 12 cross-sectional studies, 2 case series, and 10 case reports published between 1965 and 2026. A total of 404 patients had both RA and CPPD, with 397/404 (98.3%) aged over 60 years old. Of 365 patients with serostatus data, 204/339 (60.2%) were seronegative for both rheumatoid factor (RF) and anti-citrullinated protein antibody (ACPA). Radiographic chondrocalcinosis was evident in 271/287 (94.4%). Of 271 patients with chondrocalcinosis, 162 (59.8%) were seronegative for both RF and ACPA. The most prescribed medications were methotrexate and prednisolone, in 75/205 (36.6%) and 64/205 (31.2%) patients, respectively. Colchicine was prescribed for 24/205 (11.7%). CONCLUSION: While the studies were small, RA, which is commonly seronegative, and CPPD can co-exist in the elderly. Higher-quality studies are required to determine the prevalence of co-existent RA and CPPD, thereby improving insight into the epidemiology and potentially enhancing outcomes of these patients.

Global Genomic Surveillance.

Global genomic surveillance has emerged as a foundational pillar of public health in the twenty-first century, enabling real-time tracking of pathogen evolution and informing outbreak response. This chapter examines the strategic architecture of global genomic surveillance, focusing on its application to arboviruses such as chikungunya virus (CHIKV). It explores the integration of genomic data with epidemiological, clinical, and environmental information within a One Health framework, while addressing critical challenges in governance, equity, and interoperability. The discussion covers the entire genomic surveillance workflow, from sample collection and sequencing to bioinformatic analysis and phylogenetic inference, and highlights the transformative role of artificial intelligence (AI) in predictive surveillance. By analyzing global initiatives, operational barriers, and emerging technologies, this chapter underscores the necessity of sustainable, equitable, and interoperable genomic systems to proactively address current and future infectious disease threats.

Systematic Dissection of Key Driver Perturbation Signatures in Single Cells via ECCITE-seq.

CRISPR screens, such as expanded CRISPR-compatible cellular indexing of transcriptomes and epitopes by sequencing (ECCITE-seq), enable the simultaneous measurement of transcriptomes, gRNA identity, and cell-surface protein expression at single-cell resolution to systematically interrogate gene function. This platform provides a powerful and scalable experimental approach for validating disease-associated regulators identified by large-scale association studies and other computational methods, including network-based analyses of multi-omics data. Here, as an example application, we describe an ECCITE-seq framework to characterize the transcriptomic consequences of perturbing multiple neuronal key driver genes associated with Alzheimer's disease (AD) in human-induced pluripotent stem cell (hiPSC)-derived neurons. More broadly, by integrating customized pooled gRNA libraries with different CRISPR effectors across multiple cell types, this approach allows for the assessment of the regulatory impact of candidate genes implicated in development and disease processes.

Identification of Genome-Wide Chromatin Structural Aberration in Cancer by Hi-C Analysis.

Aberrant three-dimensional genome organization is a hallmark of cancer, often driving oncogene activation through mechanisms such as enhancer hijacking. High-throughput chromosome conformation capture (Hi-C) maps these interactions on a genome-wide scale. Unlike earlier dilution-based methods, in situ Hi-C performs proximity ligation within intact nuclei, minimizing random ligation noise and enabling fine-scale structure detection. This chapter describes an optimized in situ Hi-C protocol tailored for cancer cell lines using MboI digestion and biotin-mediated pull-down to generate high-complexity libraries. We further outline a computational workflow that extends beyond standard topological mapping of compartments and topologically associating domains to identify cancer-specific aberrations. Specifically, we focus on detecting chromosomal rearrangements (structural variants) and characterizing the distinct circular topology of extrachromosomal DNA. This integrated experimental and analytical framework provides the necessary tools to dissect the spatial dysregulation underlying tumor evolution.
