The prevention of sudden cardiac death remains one of the greatest challenges in the field of cardiovascular medicine today. Despite the difficulty in predicting which individuals are going to die suddenly, much knowledge has accumulated in recent years in regard to independent risk factors for SCD and moreover, different pharmacological interventions have been evaluated for the prevention of sudden coronary death. Currently, the beta-blockers are the only pharmacological agents that have been shown to reduce sudden cardiac deaths in clinical trials. The reduction in sudden death may involve several mechanisms that include antiatherosclerotic effects, antithrombotic effects, cardiac anti-ischemic effects and antifibrillatory effects.

Vision loss affects more than 7 million Americans and impacts quality of life, independence, social functioning, and overall health. Common and dangerous conditions causing sudden vision loss include acute angle-closure glaucoma, retinal detachment, retinal artery occlusion, giant cell arteritis, and optic neuritis. Acute angle-closure glaucoma features ocular pain, headache, and nausea; treatment includes pilocarpine eye drops, oral or intravenous acetazolamide, and intravenous mannitol.

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.

Sudden unexpected death in epilepsy (SUDEP) is the leading cause of epilepsy-related death, likely stemming from seizure activity disrupting vital brain centres controlling heart and breathing function. However, understanding of SUDEP's anatomical basis and mechanisms remains limited, hampering risk evaluation and prevention strategies. Prior studies using a neuron-specific conditional knockout mouse model of SUDEP identified the primary importance of brain-driven mechanisms contributing to sudden death and cardiorespiratory dysregulation; yet, the underlying neurocircuits have not been identified.

Japan is experiencing a dramatic spike in streptococcal toxic shock syndrome (STSS) cases, exceeding the previous year's statistics. This life-threatening illness, caused by , has been connected not only to the relaxation of COVID-19 precautions but also to the prolonged effects of confinement and lack of contact with the surrounding environment/ecology. The condition is characterized by a sudden onset of symptoms, including high fever, rash, and shock, and demands immediate medical intervention.
