The Hospital Ship as a Strategic Asset in21st Century Foreign Policy and Global Health Crises.
Current U.S. hospital ships-USNS Mercy and Comfort-are old, slow, cumbersome, and indefensible, and due for retirement. As new challenges and new threats emerge in the 21st century, the U.S. Navy should field new afloat medical platforms to potentially deal with both mass casualty scenarios and humanitarian disaster relief in a rapid and tactical manner. New hospital ships should be able to defend themselves with more modern weapons and to be interconnected with encrypted communications. They must be fast, nimble, tactical, defensible, and forward deployed in the risky global commons of the 21st century. ⋯ Multiple high-speed medical response vessels-whether reconfigured from an existing ship, or an entirely new platform developed for more robust medical delivery-need to be urgently fielded for future combat operations, humanitarian missions, and participation in cooperative security engagements. These medical platforms need to be able to defend themselves and be tactically interconnected with the Fleet and Fleet Forces.

ReviewA zero-sum game or an interactive frame? Iron competition between bacteria and humans in infection war.
Iron is an essential trace element for both humans and bacteria. It plays a vital role in life, such as in redox reactions and electron transport. Strict regulatory mechanisms are necessary to maintain iron homeostasis because both excess and insufficient iron are harmful to life. ⋯ Meanwhile, researchers have invented detection test strips and coupled antibiotics with siderophores to create tools that take advantage of this battle for iron, to help eliminate pathogens. In this review, we summarize bacterial and human iron metabolism, competition for iron between humans and bacteria, siderophore sensors, antibiotics coupled with siderophores, and related phenomena. We also discuss how competition for iron can be used for diagnosis and treatment of infection in the future.

Cancer is one of the most prevalent diseases worldwide, and poses a threat to human health. Noncoding RNAs (ncRNAs) constitute most transcripts, but they cannot be translated into proteins. Studies have shown that ncRNAs can act as tumor suppressors or oncogenes. ⋯ There is a complex network of interactions between ncRNAs, with some lncRNAs and circRNAs acting as competitive endogenous RNAs (ceRNAs) to decoy miRNAs and repress their expression. The ceRNA network is a part of the ncRNA network and numerous ncRNAs work as nodes or hubs in the network, and disruption of their interactions can cause cancer development. Therefore, the balance and stabilization of this network are important for cancer diagnosis and treatment.

Since January 2022, there has been an increase in reports of cases of acute hepatitis of unknown cause in children. Although cases have been reported across multiple continents, most have been reported in the United Kingdom. Investigations are ongoing to identify the causative agent or agents. ⋯ In this series involving 44 young children with acute hepatitis of uncertain cause, human adenovirus was isolated in most of the children, but its role in the pathogenesis of this illness has not been established.

Epidemic risk assessment and response relies on rapid information sharing. Using examples from the past decade, we discuss the limitations of the present system for outbreak notifications, which suffers from ambiguous obligations, fragile incentives, and an overly narrow focus on human outbreaks. We examine existing international legal frameworks, and provide clarity on what a successful One Health approach to proposed international law reforms-including a pandemic treaty and amendments to the International Health Regulations-would require. In particular, we focus on how a treaty would provide opportunities to simultaneously expand reporting obligations, accelerate the sharing of scientific discoveries, and strengthen existing legal frameworks, all while addressing the most complex issues that global health governance currently faces.
