There are ethical dilemmas faced by clinicians when responding to using unregistered medical devices, such as innovative internet technologies for managing type 1 diabetes mellitus. This chronic disease significantly impacts patients' health, requiring intensive daily activities like blood glucose monitoring, insulin injections, and specific dietary recommendations. Recent technological advances, including continuous glucose monitors and insulin pumps, have been shown to improve glycemic control. Di-it Yourself Artificial Pancreas Systems are emerging open-source automated delivery methods initiated by the diabetes community, although they are not clinically evaluated and present a liability challenge for healthcare providers. To use them or not? Should parents and healthcare providers use such technology that helps, but is not proven?Having all of that in mind, we argue that the World Health Organization's (WHO) definition of health is outdated, advocating for the "Extended Health Hypothesis". This hypothesis claims that health extends beyond traditional biological boundaries to include essential functional structures like diabetes-related technology, making technology a part of a patient's health. This view aligns with the "Extended Mind Hypothesis," suggesting that health should include elements beyond organic material if they are vital to a patient's functions.In the commentary, we highlight that both naturalist and normative conceptions of health support the extended health hypothesis, emphasizing that human health is not confined to organic material. This perspective raises critical questions about whether devices like insulin pumps and continuous glucose monitors are integral to a patient's health and whether their malfunction constitutes a form of disease. Devices are considered integral to health, there is no ethical dilemma in using unregistered medical devices for managing type 1 diabetes. Finally, we call for reevaluating the definitions of health and patients, particularly for children with type 1 diabetes using advanced technologies. It asserts that the optimal use of such devices represents a new form of health, creating a health-device symbiosis that should be evaluated with the child's best interests in mind., Competing Interests: Declarations.

Introduction: Total breast reconstruction with autologous fat transfer (AFT) is a relatively new breast reconstruction method. Although AFT was predominantly used to correct postsurgical defects, the surgical skills of a total breast reconstruction with AFT are different and can be facilitated for novices to accelerate their learning process. This study aims to assess the learning curve of plastic surgeons in total breast reconstruction with AFT in the Netherlands., Methods: A mixed-methods study was performed based on the multicenter randomized clinical BREAST trial data. For the qualitative analysis, semistructured interviews were conducted. To test hypotheses derived from the qualitative data, retrospective data analysis was performed using multilevel linear regression analysis of the patients undergoing AFT as a total breast reconstruction method., Results: The interviews revealed that plastic surgeons need to perform the procedure several times to learn and experience the technical details of total breast reconstruction with AFT. Learning and improving this technique works best by scrubbing in with an expert. Before plastic surgeons learn the optimal volume of fat reinjection over time, they tend to inject too little fat and subsequently too much fat over multiple procedures. With more experience, the rigottomy technique becomes more important. Besides technical details, managing patient expectations before starting treatment is paramount. Multilevel linear regression revealed a significant decrease ( P < 0.001) in the number of surgical procedures and the total injected volume ( P = 0.002) to complete a total breast reconstruction with AFT., Conclusions: This is the first study that explores the learning curve involved in using AFT as a total breast reconstruction method. The feeling of when fat transfer is sufficient, and how to release scars for a good result without causing seromas, is best learned by scrubbing in with experienced colleagues during several procedures, interchanged with starting one's own practice., Competing Interests: The authors have declared they have no conflicts of interest., (Copyright © 2024 Wolters Kluwer Health, Inc.

Technology is increasingly shaping human life, particularly in healthcare, where recent advancements have revolutionized patient care. Despite these advances, the World Health Organization's (WHO) definition of health remains rooted in traditional notions, raising questions about its adequacy in light of technological progress. This paper explores the conceptual and practical limitations of the current definition and argues for its revision to encompass the role of technology in health. This paper examines the evolving landscape of healthcare technology and its philosophical implications, drawing on theories such as the Extended Health Hypothesis and the Extended Mind Hypothesis. It claims that health extends beyond traditional biological boundaries and includes the influence of technology on well-being. This paper advocates for a re-examination of the WHO definition of health to reflect the integral role of technology in modern healthcare. Recognizing technology as part of health necessitates a broader conceptual framework that acknowledges the interconnectedness of biology, technology, and human well-being. Given technology's transformative role in healthcare, this paper argues for a revaluation of the WHO's definition of health to encapsulate the evolving relationship between technology and human well-being. At the end, we propose a new definition recognizing that health is a dynamic state of physical, mental, social, and technological well-being, wherein individuals can achieve optimal quality of life through the harmonious integration of biological, psychological, and technological factors. This state encompasses not only the absence of disease but also the effective utilization of advanced technologies.

LRFN5 is a regulator of synaptic development and the only gene in a 5.4 Mb mammalian-specific conserved topologically associating domain (TAD); the LRFN5 locus. An association between locus structural changes and developmental delay (DD) and/or autism was suggested by several cases in DECIPHER and own records. More significantly, we found that maternal inheritance of a specific LRFN5 locus haplotype segregated with an identical type of autism in distantly related males. This autism-susceptibility haplotype had a specific TAD pattern. We also found a male/female quantitative difference in the amount histone-3-lysine-9-associated chromatin around the LRFN5 gene itself (p < 0.01), possibly related to the male-restricted autism susceptibility. To better understand locus behavior, the prevalence of a 60 kb deletion polymorphism was investigated. Surprisingly, in three cohorts of individuals with DD (n = 8757), the number of deletion heterozygotes was 20%-26% lower than expected from Hardy-Weinberg equilibrium. This suggests allelic interaction, also because the conversions from heterozygosity to wild-type or deletion homozygosity were of equal magnitudes. Remarkably, in a control group of medical students (n = 1416), such conversions were three times more common (p = 0.00001), suggesting a regulatory role of this allelic interaction. Taken together, LRFN5 regulation appears unusually complex, and LRFN5 dysregulation could be an epigenetic cause of autism. LAY SUMMARY: LRFN5 is involved with communication between brain cells. The gene sits alone in a huge genomic niche, called the LRFN5 locus, of complex structure and high mammalian conservation. We have found that a specific locus structure increases autism susceptibility in males, but we do not yet know how common this epigenetic cause of autism is. It is, however, a cause that potentially could explain why higher-functioning autism is more common in males than females., (© 2022 The Authors.
