    Abstract Introduction: Although there is low-quality evidence, there has been an increase in publications on the experience of evaluating and managing cancer-related breathlessness using opioids other than morphine.
    Methods: The author conducted a non-systematic literature review in the PubMed/Medline and Embase until 4 October 2022. Eligible studies have evaluated the efficacy of opioids other than morphine for cancer-related breathlessness. Studies focused on sedation, anaesthesia, paediatric patients, opioid toxicity or basic research were excluded. Reviews/meta-analyses and non-English language publications were also excluded.
    Results: A total of 1556 records were identified, of which 23 studies including 469 patients who were treated with fentanyl (n=223), oxycodone (n=171) and hydromorphone (n=75) were considered eligible. Six phase II randomised clinical trials (RCTs), four observational studies and four case reports of fentanyl were found. For breathlessness on exertion, fentanyl yielded promising results, but no RCT showed significant superiority of fentanyl to placebo or morphine. For terminal breathlessness, three RCTs, five non-randomised or observational studies and one case report on oxycodone or hydromorphone were found. Although the results of the observational studies suggested that oxycodone and hydromorphone might be effective alternatives to morphine, the superiority over placebo or non-inferiority to morphine had not been demonstrated in the RCTs.
    Conclusion: As an alternative to morphine, the author recommends fentanyl for breathless crisis or breathlessness on exertion, and oxycodone or hydromorphone for terminal breathlessness in advanced cancer. Larger and well-designed studies based on firm research policies are needed to confirm this current knowledge.

    Abstract Adipose tissues, such as white, brown, and beige tissues, play pivotal roles in maintaining energy balance and metabolic health. Whereas white adipocytes store energy, brown and beige adipocytes exhibit high energy expenditure owing to their distinct mitochondrial density and UCP1 expression. Dysfunction in these tissues contributes to metabolic disorders such as type 2 diabetes and cardiovascular diseases. Adipose tissue expansion through cell enlargement or increased cell numbers caused by excess energy storage in white adipocytes substantially influences metabolic health. In obesity, hypertrophic adipocytes trigger inflammation, fibrosis, and hypoxia, whereas smaller adipocytes exert favorable metabolic effects, contributing to insulin sensitivity. Brown and beige adipocytes consume energy for thermogenesis to maintain body temperature, contributing to metabolic homeostasis. The intricate interactions between brown adipose tissues and various organs, such as the liver and heart, highlight the systemic implications of adipose tissue functions. Understanding the complex underlying mechanisms may lead to the development of innovative therapies targeting metabolic disorders by modulating the functions of brown adipose tissue and its interactions with other physiological systems. In this review, we discuss insights into the mechanisms underlying the dysregulation of metabolism owing to abnormalities in adipose tissue remodeling. We focus on the endocrine functions of thermogenic brown and beige adipocytes and explore the interorgan interactions that influence whole-body metabolism.

    Abstract There are various research topics such as stochastic resonance, coherent resonance, and neuroavalanche in excitable systems under external noises. We perform numerical simulation of coupled noisy FitzHugh-Nagumo equations on the square lattice. Excitation waves are generated most efficiently at an intermediate noise strength. The cluster size distributions obey a power-law-like distribution at a certain parameter range. However, we consider that this is not a self-organized critical phenomenon, partly because the exponent of the power law is not constant. We have studied the propagation of excitation waves in the coupled noisy FitzHugh-Nagumo equations with a one-dimensional pacemaker region and found that there is a phase-transition-like phenomenon from the short-range propagation to the whole-system propagation by changing the noise strength T. The power-law distribution is observed most clearly near the phase transition of the propagation of excitation waves in the coupled noisy FitzHugh-Nagumo equations without the one-dimensional pacemaker.

    Abstract The prognosis of B-cell acute lymphoblastic leukemia in children, adolescents, and young adults has improved significantly over the second half of the last century, with long-term survival rates reaching 90%, due to risk factor stratification and risk-adjusted treatment intensity. On the contrary, there are relapsed/refractory cases, and antibody-mediated immunotherapy and chimeric antigen receptor T-cell therapy are now being used in combination with conventional chemotherapy and allogeneic hematopoietic cell transplantation; the development of this treatment is expected. Tisagenlecleucel is extensively used in Japan and abroad because of its high complete remission rate in high-risk relapsed/refractory cases, including unresponsive to chemotherapy, relapsed after transplantation, and transplant-unsuitable cases. Several studies have been published in the last 2-3 years that discuss risk factors for relapse after tisagenlecleucel and the need for consolidative therapy. This manuscript presents the direction of these discussions and perspectives.

    Abstract Obesity is a major cause of various metabolic disorders, including type 2 diabetes, nonalcoholic fatty liver disease (NAFLD) and cardiovascular diseases, in modern times. Fat tissue originally evolved as an organ to prepare for food shortages. However, when individuals consume excessive calories and engage in insufficient physical activity, it can lead to the excessive accumulation of lipids in white adipose tissue, potentially causing problems. In response to this excessive lipid accumulation extending to other tissues, insulin resistance is triggered in the body as a physiological response to prevent harmful effects. Additionally, in mammals, brown adipose tissue has evolved to generate energy and maintain body temperature. These inconspicuous defense mechanisms function coordinately to protect against systemic metabolic abnormalities affecting multiple organs. Understanding the dynamic nature of adipose tissues is now crucial for elucidating the details of the molecular abnormalities in obesity-associated metabolic diseases. This review outlines adipocyte plasticity and function with a focus on the physiological relevance and new pathways of insulin signaling.
