Background: Individuals with end-stage renal disease may be at increased risk of sudden cardiac arrest (SCA) associated with dialysis therapy. However, community-based studies with comprehensive adjudication of SCA are lacking.

Methods: We conducted a community-based study using a case-case study design in a US population of ≈1 million.

Chikungunya virus (CHIKV) is a mosquito-transmitted alphavirus causing fever, myalgia, and debilitating joint swelling and pain, which in many patients becomes chronic. The frequent epidemics of CHIKV across the world pose a significant public health burden necessitating the development of effective antiviral therapeutics. A cellular imaging-based high-content screening of natural compounds identified withaferin A (WFA), a steroidal lactone isolated from the plant Withania somnifera, as a potent antiviral against CHIKV.

Type VI secretion system (T6SS) is utilized by many Gram-negative bacteria to eliminate competing bacterial species and manipulate host cells. ATCC 17978 utilizes T6SS at the expense of losing pAB3 plasmid to induce contact-dependent killing of competitor microbes, resulting in the loss of antibiotic resistance carried by pAB3. However, the regulatory network associated with T6SS in remains poorly understood.

Article Synopsis
  • The understanding of metabolism is shifting from just powering cells and creating building blocks to recognizing its role in regulating gene expression and coordinating cellular activities.
  • Many bacterial pathogens can quickly adapt to various environments, including hostile conditions inside a host, thanks to their flexible metabolism.
  • This review emphasizes the largely overlooked impact of bacterial 'exometabolomes'—substances released by bacteria—on disease development, drug resistance, and immune system interactions, revealing new insights into how bacteria interact with their hosts.
