Effectiveness of management protocol for insulin balls in diabetics: a scoping review.

Aim: In order to achieve good glycemic control, the prevention and management of insulin balls is important for diabetic patients during insulin therapy. However, insulin balls still occur within the clinical setting. This review evaluated the effectiveness of programs designed to manage insulin balls. Methods: A scoping review was conducted based on the Japanese and English literature available from a systematic literature search conducted from January 1964 to March 2022. Three databases were searched: PubMed, CINAHL, and Ichushi-Web. Results: A total of 33 articles met the inclusion criteria, which consisted of 3 for prevention management of insulin balls and 30 for management after the occurrence of insulin balls. Findings for prevention management suggested that the insulin injection technique education (avoidance of repeated injections to the same site) and providing knowledge (about insulin balls) prevented the appearance of insulin balls. As for post-occurrence management, insulin injection technique education (avoidance of injections to the insulin ball, avoidance of repeated injections to the same site, and switching the injection site) improved blood glucose control. Hypoglycemia was observed in all studies that included an assessment of hypoglycemia. None of the studies evaluated long-term effects of either preventive or post-occurrence management. Conclusions: Providing insulin injection technique education is an effective management protocol for insulin balls. Moreover, education about hypoglycemia is important for patients with insulin balls. Further studies to investigate the long-term effects in the management of insulin balls are needed.

[Introduction of a joint academic project between the Japan Academy of Nursing Science and the Japanese Pharmacological Society: a scoping review on assessment and preventive care of insulin balls].

Japanese Academy of Nursing Science (JANS) and the Japanese Pharmacological Society (JPS) have been conducting human interaction at each other's scientific meeting symposia in a home-and-away fashion since 2018. JANS and JPS have been working on a joint scientific project, "Scoping Review: Insulin Balls" since 2021. At the 95th Annual Meeting of the JPS held in 2022, we reported from a nursing perspective on the theme of "Assessment and preventive care of insulin balls from a scoping review". Subcutaneous injection into insulin balls has been reported to cause poor blood glucose control. Therefore, it is important to prevent insulin balls. In this study, we had the research questions, "What methods are available for assessment of the insulin injection site?" and "What is the care to prevent induration and how effective is it?" and conducted a scoping review. Regarding methods of injection site assessment, most of the literature identified the injection site by palpation, visual examination, and ultrasonography. About the preventive care, there were some reports of insulin balls occurring because patients have been injecting insulin at the same site, even though healthcare professionals instructed them to avoid the same site. Some of the literature had specific teaching methods such as hand site rotation and calendar injection method, and they were reported effective. In the future, we plan to proceed with the review including care after the development of insulin balls.

Crossover trial of the effects of a far-infrared heater that heats the feet with ceramic balls on autonomic nervous activity and mood states.

INTRODUCTION: The accumulation of fatigue and stress creates problems, including reductions in quality of life and productivity. OBJECTIVES: To investigate the effects of a far-infrared heater that heats the feet with ceramic balls on autonomic nervous activity and mood states. METHODS: This study was performed as a crossover trial. Participants comprised 20 women. On different days, each participant underwent 15 min of foot warming with the far-infrared heater (far-infrared group) or remained seated for 15 min (control group). Autonomic nervous activity (low-frequency component/high-frequency component, high-frequency) and mood states scales (Profile of Mood States Second Edition and Two-Dimensional Mood Scale for Self-monitoring and Self-regulation of Momentary Mood States) during the study intervention were measured and compared between groups. RESULTS: Low-frequency/high-frequency was significantly higher in the control group 10 min after the start of intervention than at baseline (P = .033). Low-frequency/high-frequency was significantly lower in the far-infrared group than in the control group at 5 min (P = .027), 10 min (P = .011), and 15 min (P = .015). High-frequency was significantly higher in the far-infrared group at 5 min (P = .008), 10 min (P = .004), and 15 min (P = .015) than at baseline. High-frequency 5 min after the start of intervention was significantly higher in the far-infrared group than in the control group (P = .033). POMS2 scores improved significantly more in the far-infrared group than in the control group, including in fatigue-inertia (P = .019), tension-anxiety (P = .025), and total mood disturbance (P = .019). Finally, the far-infrared group showed greater improvements in Two-Dimensional Mood Scale-Short Term scores such as stability (P = .002) and pleasure (P = .013). CONCLUSION: Using the far-infrared heater to heat the feet with ceramic balls stabilized and improved mood, reduced Fatigue-Inertia and Tension-Anxiety, and alleviated total mood disturbance. Parasympathetic nervous system activation was observed from 5 min after the start of heating, suggesting that short-duration heat stimulation of the feet is effective.
