Lymphatic System and the Kidney: From Lymphangiogenesis to Renal Inflammation and Fibrosis Development.

The lymphatic kidney system plays a crucial role in managing interstitial fluid removal, regulating fluid balance, and tuning immune response. It also assists in the reabsorption of proteins, electrolytes, cytokines, growth factors, and immune cells. Pathological conditions, including tissue damage, excessive interstitial fluid, high blood glucose levels, and inflammation, can initiate lymphangiogenesis-the formation of new lymphatic vessels. This process is associated with various kidney diseases, including polycystic kidney disease, hypertension, ultrafiltration challenges, and complications post-organ transplantation. Although lymphangiogenesis has beneficial effects in removing excess fluid and immune cells, it may also contribute to inflammation and fibrosis within the kidneys. In this review, we aim to discuss the biology of the lymphatic system, from its development and function to its response to disease stimuli, with an emphasis on renal pathophysiology. Furthermore, we explore how innovative treatments targeting the lymphatic system could potentially enhance the management of kidney diseases.

"I Cry. I Simply Cry." An Ethnography of a Lymphedema Summer Camp.

Background: The aim of this study was to explore how self-management is taught, learnt, and experienced during a 3-day educational Lymphedema Camp for parents of children with lymphedema. Methods: Participants (professionals, parents, and children) were observed during camp activities and interviewed informally and formally in focus groups. The embodied nature of the experience expressed by professionals, parents, and researchers became the analytical focus for understanding the felt tensions in the teaching and learning of self-management to families. Findings: The affective sensibilities associated with the uncertainties involved in teaching and learning self-management skills were palpable given that: young people are now expected to take up strict time-consuming self-management regimens (often via the support of a parent) where "evidence-based" outcomes are uncertain or may not match the outcomes wanted by a young person (varying in age and therefore ability or willingness to engage); or where there are tensions within the family; and the variety of different professionals involved means that techniques varied but where these professionals also lacked the necessary skills training to guide them in how to teach self-management. An analytical focus on the distress, doubt, fear, loneliness, guilt, and moralism felt by professionals, parents, and the researchers supports us to identify the character of the problems associated with performing best practice care guidance where there is a lack of practical support or resources for how self-management in this population should be achieved. Conclusion: To avoid these issues more training and research are needed on "how" to self-manage and stop victim-blaming that generates tensions and drives a wedge between the carer and the cared-for. When systemic problems get located with individuals (professionals, parents, or children), this directs our attention and understanding away from systems of care that lack coordination, may be under-resourced, and where effective training is absent.

Development of Self-Efficacy Tools for Parents and Professionals Caring for Children and Young People with Lymphedema (ILF Parent SE and ILF Professional SE).

Background: Self-management is a key aspect of lymphedema treatment and self-efficacy is a key factor linked to long-term adherence to treatment. The study aimed to generate self-efficacy scales to support the care of children and adolescents with lymphedema to support self-management. Methods and Results: Parents of children with lymphedema and the professionals caring for them were recruited during a lymphedema educational camp. Six individual semistructured focus groups were undertaken in Italian, French, and English (three for parents and three for professionals) with simultaneous translation. Scale item generation was developed using interpretative phenomenological analysis and adopted Bandura's self-efficacy concept. Two self-efficacy tools were developed from research with 26 parents and 14 professionals. The parental tool (ILF parent SE) has 6 domains and 44 items: school; home and leisure; understanding the condition and treatment, and managing child and parent emotions. The professional tool (ILF Professional SE) has 4 domains and 21 items. This scale has two parts; the first indicates the level of professional autonomy in decision making, and the second covers assessment and treatment, patient understanding, and managing emotional reactions. Both tools adopt a 0- to 100-point scale using a 10-unit interval with 0 (cannot do) through to 100 (high certainty of being able to do). Initial face validity has been undertaken. Conclusion: Self-efficacy has emerged as a complex issue faced by parents and professionals involved with children and young people with lymphedema. By being able to assess the challenges parents face in self-efficacy individualized programs can be developed that will assist families in managing this complex disease and lead to greater well-being. Increased professional self-awareness will help the development of mentorship programs to support professionals dealing daily with the stress of managing a rare disease in which the outcome may be uncertain.

A Study Using Visual Art Methods to Explore the Perceptions and Barriers of Self-Management in Children and Adolescents with Lymphedema.

Background: The aims of this study were to explore, using visual art methodology, how children and adolescents perceive their lymphedema and conceptualize the barriers and enablers in self-management and to explore the role of an educational camp in promoting self-efficacy. Methods: Participants (speaking English, French, and Italian) were recruited during an educational camp for children with lymphedema. Children and adolescents used different methodologies to depict living and self-managing their condition. Younger children (aged 5-12 years) drew pictures, and all children and adolescents (aged 5-18 years) were given cameras and asked to take photographs that depicted their experience of learning self-management of their condition during the camp. Rose's critical visual methodology framework was used for analysis. Results: Analysis of the data produced five categories: Normal versus altered childhood, living with lymphedema; perceptions of lymphedema and self-care in younger children; adolescents' perception of living and managing lymphedema; learning self-efficacy; and insights into cultural differences in self-care. Conclusions: The study has shown that self-management is complex. Children and adolescents face many daily challenges and frustrations in managing their condition in addition to the normal challenges of development and growth that impact on: home life, time with friends, school activities, and relationships. Children expressed a deep longing for cure and a recognition that their lives were altered by having the condition that led to limitations in sport and wearing fashionable clothes and shoes. The importance of relationships with professionals was critical as was the experience of meeting and learning with other children through the camp experience. Attempts to simplify self-management techniques would appear to be a key priority as would a greater understanding of the self-beliefs young people have of their ability to influence and control their condition and its impact on their life.

A Study to Explore the Professional Conceptualization and Challenges of Self-Management in Children and Adolescents with Lymphedema.

Background: The aim of this study was to explore the professional experience of caring for children and adolescents with lymphedema and to explore the way in which they understand and implement self-management strategies and the influence of their own self-efficacy beliefs on this process. Methods and Results: Participants were recruited during an educational camp for children with lymphedema. Three individual semistructured focus groups were undertaken in English, French, and Italian with simultaneous translation. Data were analyzed using interpretative phenomenological analysis (IPA). Analysis of the data produced three superordinate themes: professional concepts of self-management, professional practice, and redefining the cornerstone of lymphedema care. An additional seven subthemes were as follows: readiness to self-management, professional perspectives on self-management, defining success and treatment failure, emotional burden, traditional views on complex decongestive therapy, new ways to practice, and sole practitioner versus multidisciplinary teams. Conclusions: The purpose of the study was to explore the challenges professionals face when introducing self-management to children and adolescents with lymphedema and their parents and to explore their own sense of self-efficacy in approaching this. The research allowed in-depth discussion about the ways they conceptualize self-management and faced professional challenges. The research highlighted the need to define what is considered an acceptable outcome within a complex and uncertain condition and the self-management strategies that are needed to support this.

A Study to Explore the Parental Impact and Challenges of Self-Management in Children and Adolescents Suffering with Lymphedema.

Background: Limited research has shown the impact lymphedema has on children and families. The aim of this study was to explore the parental experience of caring for a child or adolescent with lymphedema and the daily challenges of self-management and self-efficacy. Methods and Results: Participants were recruited during an educational camp for children with lymphedema (N = 26). Three individual semistructured focus groups were undertaken in English, French, and Italian with simultaneous translation. Data were analyzed using interpretative phenomenological analysis. Analysis identified four superordinate themes; the journey, treatment management, independence, and psychosocial impact. Ten subthemes were identified: bandaging/compression, professional support, holistic care, fear, self-efficacy, acceptance, friendship, guilt, distress, and hope. Conclusions: Parental self-management of children with lymphedema is complex and invades many aspects of life. Lack of professional agreement over what constitutes self-management leads to parental confusion and anxiety. Self-management is demanding, and parents are ambivalent to its effectiveness, but choose to persevere through fear of their child's condition deteriorating. Self-efficacy is evident in complex problem solving, despite parents believing that they are not adequately prepared for this.
