Intercellular mitochondria transfer is an evolutionarily conserved process in which one cell delivers some of their mitochondria to another cell in the absence of cell division. This process has diverse functions depending on the cell types involved and physiological or disease context. Although mitochondria transfer was first shown to provide metabolic support to acceptor cells, recent studies have revealed diverse functions of mitochondria transfer, including, but not limited to, the maintenance of mitochondria quality of the donor cell and the regulation of tissue homeostasis and remodelling.

Patient-reported health status is an important assessment of patients with heart failure, but current approaches have substantial methodological and analytical limitations. Changes in the Kansas City Cardiomyopathy Questionnaire (KCCQ) are commonly presented as a measure of the effect of drugs and devices, most often as the between-group difference in population means or as the odds of showing threshold changes of 5, 10, 15, and 20 points. However, the presentation of mean differences is based on statistical assumptions that are routinely violated in most trials.

In most bacteria, cell division depends on the tubulin-homolog FtsZ that polymerizes in a GTP-dependent manner to form the cytokinetic Z-ring at the future division site. Subsequently, the Z-ring recruits, directly or indirectly, all other proteins of the divisome complex that executes cytokinesis. A critical step in this process is the precise positioning of the Z-ring at the future division site.

There is a new awareness of the widespread nature of metabolic dysfunction-associated steatotic liver disease (MASLD) and its connection to cardiovascular disease (CVD). This has catalyzed collaboration between cardiologists, hepatologists, endocrinologists, and the wider multidisciplinary team to address the need for earlier identification of those with MASLD who are at increased risk for CVD. The overlap in the pathophysiologic processes and parallel prevalence of CVD, metabolic syndrome, and MASLD highlight the multisystem consequences of poor cardiovascular-liver-metabolic health.

Randomized clinical trials (RCTs) for hypertrophic cardiomyopathy (HCM) have long been challenging caused by the condition's rarity, low event rates, and diverse clinical presentations. However, recent advances in targeted therapies have sparked increased interest in HCM research. Despite this, designing effective RCTs remains complex, particularly in identifying clinically meaningful endpoints.
