The role of the nurse in the care and management of patients with atopic dermatitis

Background The purpose of this paper is to provide an overview of key aspects of specialised dermatology nursing practice in the management of patients with moderate to severe atopic dermatitis. The role of dermatology nurse specialists in supporting patients and promoting disease understanding, education and treatment adherence continues to evolve. As features of specialised nursing care can also inform other nursing staff in a wide range of care settings, an overview of key components is examined. Observations presented are from a pan-European perspective and represent the collected view of a group of dermatology nurse specialists, dermatologists and patient advocates following two round-table discussions. Discussion Atopic dermatitis is a common, chronic, inflammatory disease characterised by erythematous/scaling skin lesions, with often intense pruritus. Disease course is cyclic with periodic disease flares of varying intensity, presenting management challenges to patients and families. Dermatology nurse specialists play a key role in providing education and substantial patient support to improve treatment outcomes and quality of life to patients and their family, delivered within a multidisciplinary team framework. Nurse-led education and ‘eczema schools’ are of benefit in reducing disease severity and improving quality of life by enhancing self-management, adherence and patient engagement. eHealth tools, such as patient portals or online training platforms, can provide online learning, individualised education, and help to improve engagement. These and other initiatives, such as written action plans, are all essential to improve or maintain treatment adherence, self-management and quality of life. Summary Dermatology nurse specialists play a central role in the assessment and management of moderate to severe atopic dermatitis patients and families. This places them in an ideal position to build strong and often long-term relationships with patients and parents. Such engagement promotes trust, assists in setting realistic expectations of treatment and outcomes, and enhances self-management and engagement in their own care. Providing emotional support, as well as formal and systematic education (including individualised practical advice) all contribute to improved treatment adherence and can enhance the quality of life of patients and their families throughout the course of this long-term condition

Patterns of Multimorbidity in the Aged Population. Results from the KORA-Age Study

Multimorbidity is a common problem in aged populations with a wide range of individual and societal consequences. The objective of the study was to explore patterns of comorbidity and multimorbidity in an elderly population using different analytical approaches. Data were gathered from the population-based KORA-Age project, which included 4,127 persons aged 65–94 years living in the city of Augsburg and its two surrounding counties in Southern Germany. Information on the presence of 13 chronic conditions was collected in a standardized telephone interview and a self-administered questionnaire. Patterns of comorbidity and multimorbidity were analyzed using prevalence figures, logistic regression models and exploratory tetrachoric factor analysis. The prevalence of multimorbidity (≥2 diseases) was 58.6% in the total sample. Hypertension and diabetes (Odds Ratio [OR] 2.95, 99.58% confidence interval [CI] [2.19–3.96]), as well as hypertension and stroke (OR 2.00, 99.58% CI [1.26–3.16]) most often occurred in combination. This association was independent of age, sex and the presence of other conditions. Using factor analysis, we identified four patterns of multimorbidity: the first pattern includes cardiovascular and metabolic diseases, the second includes joint, liver, lung and eye diseases, the third covers mental and neurologic diseases and the fourth pattern includes gastrointestinal diseases and cancer. 44% of the persons were assigned to at least one of the four multimorbidity patterns; 14% could be assigned to both the cardiovascular/metabolic and the joint/liver/lung/eye pattern. Further common pairs were the mental/neurologic pattern combined with the cardiovascular/metabolic pattern (7.2%) or the joint/liver/lung/eye pattern (5.3%), respectively. Our results confirmed the existence of co-occurrence of certain diseases in elderly persons, which is not caused by chance. Some of the identified patterns of multimorbidity and their overlap may indicate common underlying pathological mechanisms

Role and Regulation of Vascularization Processes in Endochondral Bones

Adequate vascularization is an absolute requirement for bone development, growth, homeostasis, and repair. Endochondral ossification during fetal skeletogenesis is typified by the initial formation of a prefiguring cartilage template of the future bone, which itself is intrinsically avascular. When the chondrocytes reach terminal hypertrophic differentiation they become invaded by blood vessels. This neovascularization process triggers the progressive replacement of the growing cartilage by bone, in a complex multistep process that involves the coordinated activity of chondrocytes, osteoblasts, and osteoclasts, each standing in functional interaction with the vascular system. Studies using genetically modified mice have started to shed light on the molecular regulation of the cartilage neovascularization processes that drive endochondral bone development, growth, and repair, with a prime role being played by vascular endothelial growth factor and its isoforms. The vasculature of bone remains important throughout life as an intrinsic component of the bone and marrow environment. Bone remodeling, the continual renewal of bone by the balanced activities of osteoclasts resorbing packets of bone and osteoblasts building new bone, takes place in close spatial relationship with the vascular system and depends on signals, oxygen, and cellular delivery via the bloodstream. Conversely, the integrity and functionality of the vessel system, including the exchange of blood cells between the hematopoietic marrow and the circulation, rely on a delicate interplay with the cells of bone. Here, the current knowledge on the cellular relationships and molecular crosstalk that coordinate skeletal vascularization in bone development and homeostasis will be reviewed.status: publishe

Signaling pathways effecting crosstalk between cartilage and adjacent tissues: Seminars in cell and developmental biology: The biology and pathology of cartilage

Endochondral ossification, the mechanism responsible for the development of the long bones, is dependent on an extremely stringent coordination between the processes of chondrocyte maturation in the growth plate, vascular expansion in the surrounding tissues, and osteoblast differentiation and osteogenesis in the perichondrium and the developing bone center. The synchronization of these processes occurring in adjacent tissues is regulated through vigorous crosstalk between chondrocytes, endothelial cells and osteoblast lineage cells. Our knowledge about the molecular constituents of these bidirectional communications is undoubtedly incomplete, but certainly some signaling pathways effective in cartilage have been recognized to play key roles in steering vascularization and osteogenesis in the perichondrial tissues. These include hypoxia-driven signaling pathways, governed by the hypoxia-inducible factors (HIFs) and vascular endothelial growth factor (VEGF), which are absolutely essential for the survival and functioning of chondrocytes in the avascular growth plate, at least in part by regulating the oxygenation of developing cartilage through the stimulation of angiogenesis in the surrounding tissues. A second coordinating signal emanating from cartilage and regulating developmental processes in the adjacent perichondrium is Indian Hedgehog (IHH). IHH, produced by pre-hypertrophic and early hypertrophic chondrocytes in the growth plate, induces the differentiation of adjacent perichondrial progenitor cells into osteoblasts, thereby harmonizing the site and time of bone formation with the developmental progression of chondrogenesis. Both signaling pathways represent vital mediators of the tightly organized conversion of avascular cartilage into vascularized and mineralized bone during endochondral ossification.status: publishe

City logistics by water : good practices and scope for expansion

Urban freight transport became a specific research topic as the general awareness on the increasing negative effects of these freight delivery activities on the local livability grows. The awareness for external costs (congestion, emissions, noise and road safety) by the public grew. As a result, (local) governments implemented specific policies. Often, these limit the free, flow of traffic, put limits on (un)loading activities and limit urban road capacity. As a result, logistics entrepreneurs innovate their last mile transport operations. An under-investigated opportunity is the use of waterways for urban freight delivery purposes. This chapter lists best practices found in Western Europe. These transport freight towards or in the city. In this chapter, a Dutch concept was translated into a specific case for the Belgian city of Ghent. A cost simulation of an urban delivery concept with an electrically-powered vessel is developed and gives us insight in the actual competitiveness. Based on our own simulation, conclusions are drawn. Further research opportunities are indicated
