Article Abstract
The global aging population brings about various age-related clinical concerns, including sarcopenic obesity (SO), which poses a significant health risk for older individuals. SO is characterized by the coexistence of two phenotypes, namely, sarcopenia and obesity, and its pathogenesis is multifaceted. Current research indicates that both reduced muscle mass and excessive fat accumulation are associated with chronic low-grade inflammatory conditions. In addition, these two issues have the potential to exacerbate each other's effects. This review highlights recent advances in understanding the role of immunity and inflammation in the development of SO. Specifically, we provide a novel perspective by integrating how aging and obesity jointly contribute to SO through immune-inflammatory pathways. Furthermore, we discuss the influence of sex differences in immune responses and inflammatory processes, which may account for the variability observed in SO susceptibility and progression. Finally, we summarize current and emerging therapeutic strategies to provide potential directions for the treatment of SO.

Soft tissue sarcomas (STS) are a heterogeneous group of rare malignant tumors arising from mesenchymal tissues, with extremity and superficial trunk STS (eSTS) comprising the majority of cases. The management of localized eSTS requires a multidisciplinary approach to optimize oncologic and functional outcomes. This review outlines the natural history, diagnostic workup, and treatment principles for localized eSTS, emphasizing the role of histology-specific considerations in guiding management strategies.

Objective: CircRNAs are involved in cancer progression. However, their role in immune escape in non-small cell lung cancer (NSCLC) remains poorly understood.
Methods: This study employed RIP-seq for the targeted enrichment of circRNAs, followed by Western blotting and RT-qPCR to confirm their expression.

The complex interplay between circulating metabolites and immune responses, which is pivotal to disease pathophysiology, remains poorly understood and understudied in systematic research. Here, we performed a comprehensive analysis of the immune response and circulating metabolome in two Western European cohorts (534 and 324 healthy individuals) and one from sub-Saharan Africa (323 healthy donors). At the metabolic level, our analysis revealed sex-specific differences in the correlation between phosphatidylcholine and cytokine responses following ex vivo stimulation.

Small cell lung cancer (SCLC) is a highly aggressive type of lung cancer, characterized by rapid proliferation, early metastatic spread, frequent early relapse and a high mortality rate. Recent evidence has suggested that innervation has an important role in the development and progression of several types of cancer. Cancer-to-neuron synapses have been reported in gliomas, but whether peripheral tumours can form such structures is unknown.

Individuals with progressive liver failure risk dying without liver transplantation. However, our understanding of why regenerative responses are disrupted in failing livers is limited. Here, we perform multiomic profiling of healthy and diseased human livers using bulk and single-nucleus RNA- and ATAC-seq.
