Coronary microembolization (CME) is defined as atherosclerotic plaque erosion, spontaneous rupture, or rupture of the plaque while undergoing interventional therapy resulting in the formation of tiny emboli that obstruct the coronary microcirculatory system. For percutaneous coronary intervention, CME is a major complication, with a periprocedural incidence of up to 25%. ⋯ The aim of this review is to summarize the currently known molecular mechanisms underlying CME. Further investigations of the RCD mechanisms may unravel new avenues for the prevention and treatment of CME.

Aminoglycosides and cisplatin drugs are extensively utilized for their high efficacy in treating various conditions in the clinic, however, their ototoxic side effects warrant significant attention. These drugs could penetrate the inner ear via specific channels or transporters, which not only affect the survival of hair cells but also induce the overproduction of reactive oxygen species. Currently, scientific research mainly addresses this issue through the downstream intervention of reactive oxygen species. ⋯ It is, therefore, imperative to investigate the regulatory role of the MET channel in the up-taking of ototoxic drugs, serving as a pivotal point for the development of preventative and therapeutic approaches. This review aims to highlight the mechanism of inhibition of ototoxic substances absorption by auditory hair cells, explore how to develop novel ear protection methods by targeting these channels and transporters, and provide a new perspective and strategy for addressing drug-induced ototoxicity. The approach to protecting hair cells by targeting these channels and transporters not only broadens our understanding of the underlying mechanisms of ototoxicity, but could also spur further research and progress in the field of auditory protection.

Background: Evidence increasingly indicates that HPV infection plays a pivotal role in the initiation and progression of bladder cancer (BC). Yet, determining the predictive value of HPV-associated genes in BC remains challenging. Methods: We identified differentially expressed HPV-associated genes of BC patients from the TCGA and GEO databases. ⋯ Risk scores were correlated with tumor microenvironment (TME) scores, immune cell infiltration, and sensitivities to both chemotherapy and immunotherapy. Conclusion: We have formulated a risk-assessment model pinpointing 13 central HPV-associated genes in BC. These genes present potential as prognostic indicators and therapeutic targets, emphasizing the intertwined relationship between HPV-induced BC progression and the immune landscape.

Purpose: To evaluate the association between coronary heart disease (CHD) severity and the risk of developing keratopathy. Method: A retrospective cohort study was conducted with data from the Taiwan National Health Insurance Research Database (NHIRD). A total of 593100, 593100 and 296500 patients were included in the control, mild CHD and severe CHD groups, respectively. ⋯ The cumulative incidence of superficial keratopathy was also significantly greater in the severe CHD group than in the mild CHD group (P < 0.001). In the subgroup analyses, the incidence of superficial keratopathy was significantly greater in severe CHD patients than in mild CHD patients older than 70 years, and the correlation between CHD severity and superficial keratopathy incidence was significantly greater in those older than 70 years of age (P = 0.002). Conclusions: Severe CHD is related to a greater risk of developing superficial keratopathy, especially in those older than 70 years of age.

Background: A more accurate assessment of extrahepatic metastases (EHMs) with colorectal cancer liver metastases (CRLMs) improve patient prognosis without unnecessary surgery and economic burden. At present, PET-CT can only be used as a second-line modality. We aimed to construct a predictive model for EHMs, and provide guidance for the selective application of 18F-FDG PET/CT. ⋯ The nomogram model achieved stable and accurate prediction results in the training and validation sets (AUC = 0.768 and 0.733), and was significantly superior to CEA and CA19-9. Moreover, the sensitivity and specificity of 18F-FDG PET/CT for the diagnosis of EHMs were 100% and 88%, respectively. Conclusions: We constructed and validated a nomogram on predicting the risk of EHMs in patients with CRLMs, which can guide clinicians to selective application of 18F-FDG PET/CT.
