Primary Care and Emergency Department Management of the Patient With Duchenne Muscular Dystrophy

Primary care providers (PCPs) are usually the first point of contact with the health care system for patients with Duchenne muscular dystrophy (DMD), and patients often present to emergency departments in which providers have little experience in dealing with this condition. With this article, we give primary care and emergency medicine providers a background in the common issues that affect people with DMD. By acquiring some specialized knowledge about the multisystem medical complications of DMD and by applying general principles of primary care, such as timely immunization, anticipatory safety counseling, behavioral screening, and routine nutritional and developmental assessments, the PCP can be a valued and effective medical provider to patients with DMD. The PCP can provide access to and effective coordination among the patient's specialty caregivers. Moreover, the PCP can become a trusted advisor to the patient and his family about important medical decisions, as well as issues in the psychosocial, behavioral, and educational domains. This article also contains a "pocket guide" used to assess and manage common urgent medical problems that cause patients with DMD to seek care in the emergency department. With the background information discussed in this article, both PCPs and emergency medicine physicians can skillfully care for patients with DMD in their respective settings, optimizing patient outcomes

Moving beyond the 2018 minimum international care considerations for osteoporosis management in duchenne muscular dystrophy (DMD): Meeting report from the 3rd International Muscle-Bone Interactions Meeting 7th and 14th November 2022

This current manuscript summarizes the proceedings of the “Third Muscle-bone interactions in Duchenne Muscular Dystrophy Symposium: Moving Beyond the 2018 Minimum International Standards of Care for Osteoporosis Management”, an event co-organized by the World Duchenne Organization (www.worldduchenne.org) and the International Conference on Children’s Bone Health (www.theiscbh.org). This virtual symposium, held on November 7th and 14th 2022, brought together a total of 385 delegates representing 55 countries registered for the symposium, which included 239 clinicians, 70 researchers, 40 patient representatives and others from pharmaceutical companies and regulators. This symposium aimed to review the evidence base that informed the 2018 international minimum Care Considerations, best practices for implementation of these Care Considerations, and emerging knowledge that has arisen from research since the 2018 Care Considerations that shines light on the path forward. The online symposium and this report cover the following areas: 1. Current understanding of the bone morbidity in DMD, especially in relation to conventional glucocorticoid therapy. 2. The published, 2018 minimum international Care Considerations for osteoporosis monitoring and management in DMD. 3. Real world initiatives and challenges in the implementation of the 2018 minimum international Care Considerations for osteoporosis monitoring and management in DMD. 4. The need to consider strategies to move beyond the 2018 minimum international Care Considerations to prevent first fractures in DMD. 5. New therapies in DMD with potential impact on skeletal outcomes

Moving Beyond the 2018 Minimum International Care Considerations for Osteoporosis Management in Duchenne Muscular Dystrophy (DMD)

Individuals living with Duchenne muscular dystrophy (DMD) are at significant risk of bone fragility due to osteoporosis, with the most potent drivers of fragility fractures in this context stemming from the aggressive myopathy and long term oral glucocorticoid therapy. Young people with DMD have a high fracture burden, with reported total and vertebral fracture rates that are four [1, 2] and 535 times [1] higher than those of healthy growing boys, respectively. Vertebral fractures can occur as early as six months following daily glucocorticoid initiation [3]. Up to 75% of young people with DMD sustain at least one fracture after eight years of glucocorticoid therapy [4]. Fractures in DMD can lead to devastating outcomes, including steeper rates of functional decline, premature and permanent loss of ambulation, chronic pain, and even death from fat embolism syndrome or adrenal crisis following long bone fractures [2, 5–8]. The potential for serious consequences and medical complications linked to fractures has driven efforts to develop effective guidelines for timely bone health surveillance and treatment with more recent efforts to develop fracture prevention strategies.To guide clinicians in the management of DMD and its related co-morbidities (including skeletal health), the first internationally-endorsed, minimum standards of care were published in 2010 under the moniker “Clinical Care Considerations” [9, 10]. This document recommends that osteoporosis monitoring include spine x-rays if back pain or kyphosis is present, followed by initiation of intravenous bisphosphonate therapy if vertebral fractures are identified [10]. In the years following the inaugural 2010 Clinical Care Considerations, studies were published showing that vertebral fractures, a key manifestation of bone fragility among children and adults living with glucorticoid-treated chronic conditions, were frequently asymptomatic, necessitating routine surveillance for early detection [3, 11]. It was also better appreciated that even a single long bone fracture can signal osteoporosis in a persistently high-risk setting such as DMD, and prompt initiation of bone protection therapy is important.With this new knowledge, the latest international, minimum standards of clinical care for DMD published in 2018, known as Care Considerations [12–14], recommended routine, standardized spine imaging for early detection of vertebral fractures, combined with more timely bone-targeted (bisphosphonate) intervention in the presence of vertebral or low trauma long bone fractures [12]. At the same time, the ever-changing therapeutic landscape for the treatment of the underlying condition calls for ongoing examination of the intimate relationship between muscle and bone development in DMD, including the effect of different DMD treatment approaches on the skeletal and endocrine systems. The overall goal of such focus is to harvest discussions about optimal management that will foster bone strength and prevent fractures in this high-risk setting across all underlying disease-targeted treatment paradigms for people with DMD

Stakeholder cooperation to overcome challenges in orphan medicine development: The example of Duchenne muscular dystrophy

Duchenne muscular dystrophy is a rare, progressive, muscle-wasting disease leading to severe disability and premature death. Treatment is currently symptomatic, but several experimental therapies are in development. Implemented care standards, validated outcome measures correlating with clinical benefit, and comprehensive information about the natural history of the disease are essential for regulatory approval of any treatment. However, for Duchenne muscular dystrophy and other rare diseases, these requirements are not always in place when potential therapies enter the clinical trial phase. A cooperative effort of stakeholders in Duchenne muscular dystrophy-including representatives from patients' groups, academia, industry, and regulatory agencies-is aimed at addressing this shortfall by identifying strategies to overcome challenges, developing the tools needed, and collecting relevant data. An open and constructive dialogue among European stakeholders has positively affected development of treatments for Duchenne muscular dystrophy; this approach could serve as a paradigm for development of treatments for rare diseases in general

Directive versus empowering leadership: A field experiment comparing impacts on task proficiency and proactivity

Using a field experiment in the United Arab Emirates, we compared the impacts of directive and empowering leadership on customer-rated core task proficiency and proactive behaviors. Results of tests for main effects demonstrated that both directive and empowering leadership increased work unit core task proficiency, but only empowering leadership increased proactive behaviors. Examination of boundary conditions revealed that directive leadership enhanced proactive behaviors for work units that were highly satisfied with their leaders, whereas empowering leadership had stronger effects on both core task proficiency and proactive behaviors for work units that were less satisfied with their leaders. We discuss implications for both theory and practice. © Academy of Management Journal
