Purpose of review: This review aims to address the gap in radiation therapy (RT) care for elderly cancer patients. It will discuss the barriers to implementing effective RT in elderly and frail patients with a focus on breast cancer and metastatic settings.

Recent findings: Recent studies indicate that SBRT provides better pain control for bone metastases compared to cEBRT, but elderly patients are underrepresented in these trials. Evidence on the effectiveness of geriatric assessment tools in predicting RT tolerance and toxicity is mixed, with some studies showing a correlation while others do not. Comprehensive geriatric assessments, though promising, are often impractical due to time and resource constraints.

Summary: There is a critical need for more inclusive research to better understand the risks and benefits of RT in elderly patients. Developing streamlined geriatric assessment tools and integrating them into clinical practice can enhance treatment personalization. Future studies should prioritize elderly populations to generate robust data, thereby improving RT outcomes and quality of life for this growing patient group.

Purpose of review: Breathlessness remains a common and distressing symptom among people with serious illness, particularly in advanced disease. This review synthesises recent advances in the development, characteristics, and outcomes of breathlessness support services.

Recent findings: The expanding body of evidence regarding breathlessness support services has broadened and strengthened our understanding of clinical and cost-effectiveness. The expansion of these services, into diverse settings and including digital delivery, has augmented their reach and accessibility to a wider population. Additionally, there is increasing attention to the psychological aspects of breathlessness and its management, including the challenges of optimising breathlessness support services for long-term benefit.

Summary: Recent studies have made substantial progress in enhancing our knowledge of breathlessness support services and their impact on people with serious illness. Innovations extending services into new countries and settings, including use of digital platforms for intervention delivery, plus increased recognition of psychological mechanisms, have the potential to support more people with serious illness to live as best as possible with breathlessness.

Purpose of review: The importance of the gut microbiome for human health and well-being is generally accepted, and elucidating the signaling pathways between the gut microbiome and the host offers novel mechanistic insight into the (patho)physiology and multifaceted aspects of healthy aging and human brain functions.

Recent findings: The gut microbiome is tightly linked with the nervous system, and gut microbiota are increasingly emerging as important regulators of emotional and cognitive performance. They send and receive signals for the bidirectional communication between gut and brain via immunological, neuroanatomical, and humoral pathways. The composition of the gut microbiota and the spectrum of metabolites and neurotransmitters that they release changes with increasing age, nutrition, hypoxia, and other pathological conditions. Changes in gut microbiota (dysbiosis) are associated with critical illnesses such as cancer, cardiovascular, and chronic kidney disease but also neurological, mental, and pain disorders, as well as chemotherapies and antibiotics affecting brain development and function.

Summary: Dysbiosis and a concomitant imbalance of mediators are increasingly emerging both as causes and consequences of diseases affecting the brain. Understanding the microbiota's role in the pathogenesis of these disorders will have major clinical implications and offer new opportunities for therapeutic interventions.

Purpose of review: Cachexia is a devasting syndrome which impacts a large number of patients with cancer. This review aims to provide a comprehensive overview of the central mechanisms of cancer cachexia. In particular, it focuses on the role of the central nervous system (CNS), the melanocortin system, circulating hormones and molecules which are produced by and act on the CNS and the psychological symptoms of cancer cachexia.

Recent findings: A growing body of evidence suggests that a central mechanism of action underpins this multi-system disorder. Recent research has focused on the role of neuroinflammation that drives the sickness behaviour seen in cancer cachexia, with emphasis on the role of the hypothalamus. Melanocortin receptor antagonists are showing promise in preclinical studies. There are also new pharmacological developments to overcome the short half-life of ghrelin. GDF-15 has been identified as a core target and trials of compounds that interfere with its signalling or its central receptor are underway.

Summary: Understanding the central mechanisms of cancer cachexia is pivotal for enhancing treatment outcomes in patients. While emerging pharmacological interventions targeting these pathways have shown promise, further research is essential.

Purpose of the review: Cancer-associated cachexia is a wasting syndrome entailing loss in body mass and a shortened life expectancy. There is currently no effective treatment to abrogate this syndrome, which leads to 20-30% of deaths in patients with cancer. While there have been advancements in defining signaling factors/pathways in cancer-induced muscle wasting, targeting the same in the clinic has not been as successful. Krüppel-like factor 10 (KLF10), a transcription factor implicated in muscle regulation, is regulated by the transforming growth factor-beta signaling pathway. This review proposes KLF10 as a potential convergence point of diverse signaling pathways involved in muscle wasting.

Recent findings: KLF10 was discovered as a target of transforming growth factor-beta decades ago but more recently it has been shown that deletion of KLF10 rescues cancer-induced muscle wasting. Moreover, KLF10 has also been shown to bind key atrophy genes associated with muscle atrophy in vitro .

Summary: There is an elevated need to explore targets in cachexia, which will successfully translate into the clinic. Investigating a convergence point downstream of multiple signaling pathways might hold promise in developing effective therapies for cachexia.
