Abstract
INTRODUCTION Studies have reported health-related quality-of-life impacts of Duchenne muscular dystrophy (DMD); however, further research is needed to understand how those with DMD experience their condition and how psychosocial impacts evolve over time in response to disease progression. This qualitative study explores the social and emotional implications of key transitions, challenges and adaptations throughout the disease course from the perspective of patients and family caregivers. METHODS Semi-structured interviews were conducted with men and boys with DMD, and/or their caregivers, in the USA. Thematic analysis was used to examine patterns in data collected across the interviews. RESULTS Nineteen participants were included. Three major themes were identified: (1) barriers to participation are multifaceted; (2) an emotional journey shaped by 'inevitable progression;' (3) family provides critical tangible and emotional support. This study illustrates that psychosocial impacts of DMD are shaped by knowledge of the condition's natural history alongside other factors including the extent of social barriers, personal growth and adaptation, and family support. CONCLUSIONS Findings provide insight into the strength and resilience with which individuals and their families respond to daily challenges and major clinical milestones and highlight the relative importance of loss of upper limb function as a transition in DMD affecting health-related quality-of-life.

Abstract
Neuromuscular diseases (NMDs), in their phenotypic heterogeneity, share quite invariably common issues that involve several clinical and socio-economical aspects, needing a deep critical analysis to develop better management strategies. From diagnosis to treatment and follow-up, the development of technological solutions can improve the detection of several critical aspects related to the diseases, addressing both the met and unmet needs of clinicians and patients. Among several aspects of the digital transformation of health and care, this congress expands what has been learned from previous congresses editions on applicability and usefulness of technological solutions in NMDs. In particular the focus on new solutions for remote monitoring provide valuable insights to increase disease-specific knowledge and trigger prompt decision-making. In doing that, several perspectives from different areas of expertise were shared and discussed, pointing out strengths and weaknesses on the current state of the art on topic, suggesting new research lines to advance technology in this specific clinical field.

Abstract
OBJECTIVES There is increasing interest in expanding the elements of value to be considered when making health policy decisions. To help inform value frameworks, this study quantified preferences for disease attributes in a general public sample and examined which combination of attributes (disease profiles) are considered most important for research and treatment. METHODS A discrete choice experiment (DCE) was conducted in a US general population sample, recruited through online consumer panels. Respondents were asked to select one of a set of health conditions they believed to be most important, characterized by attributes defined by a previous qualitative study: onset age; cause of disease; life expectancy; caregiver requirement; symptom burden (characterized by the Health Utilities Index with varying levels of ambulation independence, dexterity limitations, and degree of pain and discomfort); and disease prevalence. A fractional factorial DCE design was implemented using R, and 60 choice sets were generated (separated into blocks of 10 per participant). Data were analyzed using a mixed-logit regression model, and results used to assess the likelihood of preferring disease profiles. Based on individual attribute preferences, overall preferences for disease profiles, including a profile aligned with Duchenne muscular dystrophy (DMD), were compared. RESULTS Fifty-two percent of respondents (n = 537) were female, and 70.6% were aged 18-54 years. Attributes considered most important were those related to life expectancy (odds ratio [OR], 95% confidence interval [CI] 1.88 [1.56-2.27] for a 50% reduction in remaining life expectancy vs no impact), and symptom burden (OR [95% CI] 1.84 [1.47-2.31] for severe vs mild burden). Greater importance was also found for pediatric onset, caregiver requirement, and diseases affecting more people. As an example of disease profile preferences, a DMD-like pediatric inherited disease with 50% reduction in life expectancy, extensive caregiver requirement, severe symptom burden, and 1:5000 prevalence had 2.37-fold higher odds of being selected as important versus an equivalent disease with adult onset and no life expectancy reduction. CONCLUSIONS Of disease attributes included in this DCE, respondents valued higher prevalence of disease, life expectancy and symptom burden as most important for prioritizing research and treatment. Based on expressed attribute preferences, a case study of an inherited pediatric disease involving substantial reductions to length and quality of life and requiring caregiver support has relatively high odds of being identified as important compared to diseases reflecting differing attribute profiles. These findings can help inform expansions of value frameworks by identifying important attributes from the societal perspective.

Social difficulties and care burden of adult Duchenne muscular dystrophy in Japan: a questionnaire survey based on the Japanese Registry of Muscular Dystrophy (Remudy). Orphanet J Rare Dis 2024; 19:182. [PMID: 38689355 PMCID: PMC11061927 DOI: 10.1186/s13023-024-03087-z] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/28/2023] [Accepted: 02/21/2024] [Indexed: 05/02/2024] Open
Abstract
BACKGROUND Little is known about the social difficulties and health care needs of adult Duchenne muscular dystrophy (DMD) patients in Japan, as well as the financial and physical stress experienced by their caregivers. This study aimed to clarify the social circumstances surrounding adult DMD patients and assess the degree of involvement of family members in their care and the associated economic burden of the disorder in Japan. METHODS Adult DMD patients were identified through the Registry of Muscular Dystrophy (Remudy) in Japan and invited to complete a questionnaire together with a caregiver. Data on health care use, quality of life, work status, informal care, and household expenses were collected to estimate the costs associated with DMD from social and caregiver household perspectives. RESULTS In total, 234 (63.7%) of 367 adult DMD patients (mean age, 27.4 ± 6.0; range, 20-48 years) completed the questionnaire. Of these, 38 (21%) had developmental disorders (mental retardation, autism, and learning disorders), 57 (33%) experienced bullying in school, and 44 (77%) indicated the reason for bullying to be their physical handicap. Employment histories were noted by 72 (31%), although 23 (10%) lost their jobs mainly due to physical difficulties. Of the 234 patients, 164 (74%) lived with their relatives, and 78% of care time was supplied by family members, in particular, their mothers. The mean rate of care work provided by family members was 81%. Household income of families with an adult DMD patient was lower, whereas the rate of living with parent(s) and grandparent(s) was higher, in comparison with the general Japanese population. CONCLUSIONS Adult DMD patients in Japan experience many social difficulties from childhood up to adulthood. As adults, many DMD patients experience bullying and workplace difficulties. Families were found to provide most of the care and financial support for DMD patients. Our results suggest the need to improve public patient care systems, including financial support, to address the physical and economic burdens of care for adult DMD patients in Japan.

Abstract
The dystrophinopathies encompass the phenotypically variable forms of muscular dystrophy caused by pathogenic variants in the DMD gene. The dystrophinopathies include the most common inherited muscular dystrophy among 46,XY individuals, Duchenne muscular dystrophy, as well as Becker muscular dystrophy and other less common phenotypic variants. With increased access to and utilization of genetic testing in the diagnostic and carrier setting, genetic counselors and clinicians in diverse specialty areas may care for individuals with and carriers of dystrophinopathy. This practice resource was developed as a tool for genetic counselors and other health care professionals to support counseling regarding dystrophinopathies, including diagnosis, health risks and management, psychosocial needs, reproductive options, clinical trials, and treatment. Genetic testing efforts have enabled genotype/phenotype correlation in the dystrophinopathies, but have also revealed unexpected findings, further complicating genetic counseling for this group of conditions. Additionally, the therapeutic landscape for dystrophinopathies has dramatically changed with several FDA-approved therapeutics, an expansive research pathway, and numerous clinical trials. Genotype-phenotype correlations are especially complex and genetic counselors' unique skill sets are useful in exploring and explaining this to families. Given the recent advances in diagnostic testing and therapeutics related to dystrophinopathies, this practice resource is a timely update for genetic counselors and other healthcare professionals involved in the diagnosis and care of individuals with dystrophinopathies.

Abstract
Duchenne Muscular Dystrophy (DMD) is an X-linked recessive genetic disorder characterized by progressive and severe muscle weakening and degeneration. Among the various forms of muscular dystrophy, it stands out as one of the most common and impactful, predominantly affecting boys. The condition arises due to mutations in the dystrophin gene, a key player in maintaining the structure and function of muscle fibers. The manuscript explores the structural features of dystrophin protein and their pivotal roles in DMD. We present an in-depth analysis of promising therapeutic approaches targeting dystrophin and their implications for the therapeutic management of DMD. Several therapies aiming to restore dystrophin protein or address secondary pathology have obtained regulatory approval, and many others are ongoing clinical development. Notably, recent advancements in genetic approaches have demonstrated the potential to restore partially functional dystrophin forms. The review also provides a comprehensive overview of the status of clinical trials for major therapeutic genetic approaches for DMD. In addition, we have summarized the ongoing therapeutic approaches and advanced mechanisms of action for dystrophin restoration and the challenges associated with DMD therapeutics.

Abstract
PURPOSE Considering the difficulties and challenges in Duchenne muscular dystrophy (DMD) treatment, such as the adverse effects of glucocorticoids, which are the main medical prescription used by dystrophic patients, new treatment concepts for dystrophic therapy are very necessary. Thus, in this study, we explore the effects of photobiomodulation (PBM; a non-invasive therapy) and Idebenone (IDE) treatment (a potent antioxidant), applied alone or in association, in dystrophic muscle cells and the quadriceps muscle, with special focus on autophagy and regenerative pathways. METHODS For the in vitro studies, the dystrophic primary muscle cells received 0.5J LEDT and 0.06μM IDE; and for the in vivo studies, the dystrophic quadriceps muscle received 3J LEDT and the mdx mice were treated with 200mg/kg IDE. RESULTS LEDT and IDE treatment modulate autophagy by increasing autophagy markers (SQSTM1/p62, Beclin and Parkin) and signaling pathways (AMPK and TGF-β). Concomitantly, the treatments prevented muscle degeneration by reducing the number of IgG-positive fibers and the fibers with a central nucleus; decreasing the fibrotic area; up-regulating the myogenin and MCH-slow levels; and down-regulating the MyoD and MHC-fast levels. CONCLUSION These results suggest that LEDT and IDE treatments enhance autophagy and prevented muscle degeneration in the dystrophic muscle of the experimental model. These findings illustrate the potential efficacy of LEDT and IDE treatment as an alternative therapy focused on muscle recovery in the dystrophic patient.

Abstract
Objective Skeletal muscle weakness and cardiomyopathy can be seen in carriers of dystrophinopathy. Therefore, the health management of caregivers of Duchenne/Becker muscular dystrophy (DMD/BMD) patients who are themselves carriers is an important issue. However, few studies have focused on caregivers who have dystrophin mutations. Methods In this cross-sectional study conducted at five hospitals, the daily living, situation medical treatment status, genetic testing, physical assessment, care burden, and quality of life of caregivers of DMD/BMD patients were surveyed. Results The subjects were 36 main caregivers (mean age 55.7±8.4 years old), of whom 52.8% were diagnosed as carriers, 8.3% were noncarriers, and 38.9% were not confirmed. In addition, half of the caregivers were not examined regularly at medical institutions. Of all caregivers, 54.3% had muscle or cardiac symptoms, and 75% had elevated serum creatine kinase levels. The mean Zarit Caregiver Burden Interview (ZBI) total score of current caregivers was 20.9±13.1. The frequency of a ZBI total score ≥25 was significantly higher in caregivers diagnosed as carriers than in caregivers unexamined as carriers (p=0.04). The health-related quality of life score (Short Form 36; SF-36) in caregivers was slightly lower than the Japanese standard scores in the sections of physical functioning, role limitations-physical, bodily pain, and social functioning. Conclusion Some caregivers of DMD/BMD patients can themselves have muscular or cardiac symptoms and a heavy care burden. It is therefore necessary for carrier caregivers, especially women, to undergo regular health checkups and receive appropriate health management.

Abstract
BACKGROUND AND PURPOSE Advances in multidisciplinary care are extending overall survival in Duchenne muscular dystrophy (DMD) patients. Our research objective was to delineate the clinical characteristics of this particular cohort and identify novel challenges associated with the disease. METHODS Nineteen individuals aged 25-48 years (median 34 years) with a confirmed diagnosis of out-of-frame DMD gene mutation were selected. RESULTS All patients were mechanically ventilated (5/19 via tracheostomy), with different patterns of cardiomyopathy. Swallowing and nutritional issues were frequent (median body mass index 18.95), with six cases requiring artificial enteral feeding (median age at start 29 years), as well as bone density alterations (11/19, 58%). Only 2/19 had been on long-term prednisone therapy. Issues requiring at-home/hospital assistance were respiratory infections (15/19, 79%), gastroenterological symptoms (9/19, 47%, including toxic megacolon and rectal perforation after repeated enemas), metabolic acidosis (2/19, 11%) and recurrent ischaemic strokes (1/19, 5%). From a social perspective, augmented-alternative communication devices were necessary for 7/19 (37%), with most of the patients being assisted at home and 2/19 institutionalized. Eight/19 (42%) patients experienced psychiatric symptoms (median age at presentation 16 years) and 9/19 (47%) chronic pain (median age at onset 23 years), in both cases treated with psychoactive/analgesic drugs without major adverse events. The patients' subjective perception of physical health resulted in unfavourable scores, whilst the subjective assessment of mental health unexpectedly showed more positive values compared to other chronic neurological conditions. CONCLUSIONS The analysis of adults living with DMD reveals several new health-related issues, such as the management of emergencies and safety of pharmacological treatments for psychiatric symptoms, chronic pain management, as well as an increasing caregivers burden.

Abstract
Background Duchenne Muscular Dystrophy (DMD) is a progressive genetic disease with a prevalence of 1 per 3,600-6,000 male births. Individuals with DMD are typically diagnosed at age 4-7 years; median survival is 30 years. They require multidisciplinary care, personal assistance, and often special education. Objective The aim was to assess the burden of disease in DMD in Denmark. This includes incidence, prevalence, use of healthcare services, labour market participation, educational outcomes, and overall attributable costs due to DMD. Impact on the closest relatives (siblings and parents) was also investigated. Methods The comprehensive Danish national health and administrative registers were used to assess the burden of disease following individuals with DMD and closest relatives from five years before, and up to 20 years after DMD diagnosis. Individuals with DMD (and relatives) from 1994-2021 were included. All outcomes were compared to matched control groups without the disease drawn from the Danish population. Results 213 unique individuals with DMD were identified. They had lower grades in school, required more special education and more healthcare and home care compared to their control group. The extra costs of special education summed to EUR 180,900 over the course of 11 years elementary school. They had an annual average productivity loss of EUR 20,200 between the age of 18 to 30. The extra healthcare costs of DMD in the 20 years after diagnosis were estimated to EUR 1,524,000. If an individual with DMD lives to be 30, total extra costs sum to EUR 2,365,800. Conclusions Using national register data this study presented detailed results on the burden of disease of DMD, including impact on closest relatives. With 60 additional hospital admissions and 200 extra outpatient contacts in 20 years healthcare costs, but also costs of home care and special education, increases as disease progresses.

Abstract
Objective The objective of this study was to describe predictors of loss of ambulation in Duchenne muscular dystrophy (DMD). Methods This systematic review and meta-analysis included searches of MEDLINE ALL, Embase, and the Cochrane Database of Systematic Reviews from January 1, 2000, to December 31, 2022, for predictors of loss of ambulation in DMD. Search terms included "Duchenne muscular dystrophy" as a Medical Subject Heading or free text term, in combination with variations of the term "predictor". Risk of bias was assessed using the Newcastle-Ottawa Scale. We performed meta-analysis pooling of hazard ratios of the effects of glucocorticoids (vs. no glucocorticoid therapy) by fitting a common-effect inverse-variance model. Results The bibliographic searches resulted in the inclusion of 45 studies of children and adults with DMD from 17 countries across Europe, Asia, and North America. Glucocorticoid therapy was associated with delayed loss of ambulation (overall meta-analysis HR deflazacort/prednisone/prednisolone: 0.44 [95% CI: 0.40-0.48]) (n = 25 studies). Earlier onset of first signs or symptoms, earlier loss of developmental milestones, lower baseline 6MWT (i.e.,<350 vs. ≥350 metres and <330 vs. ≥330 metres), and lower baseline NSAA were associated with earlier loss of ambulation (n = 5 studies). Deletion of exons 3-7, proximal mutations (upstream intron 44), single exon 45 deletions, and mutations amenable of skipping exon 8, exon 44, and exon 53, were associated with prolonged ambulation; distal mutations (intron 44 and downstream), deletion of exons 49-50, and mutations amenable of skipping exon 45, and exon 51 were associated with earlier loss of ambulation (n = 13 studies). Specific single-nucleotide polymorphisms in CD40 gene rs1883832, LTBP4 gene rs10880, SPP1 gene rs2835709 and rs11730582, and TCTEX1D1 gene rs1060575 (n = 7 studies), as well as race/ethnicity and level of family/patient deprivation (n = 3 studies), were associated with loss of ambulation. Treatment with ataluren (n = 2 studies) and eteplirsen (n = 3 studies) were associated with prolonged ambulation. Magnetic resonance biomarkers (MRI and MRS) were identified as significant predictors of loss of ambulation (n = 6 studies). In total, 33% of studies exhibited some risk of bias. Conclusion Our synthesis of predictors of loss of ambulation in DMD contributes to the understanding the natural history of disease and informs the design of new trials of novel therapies targeting this heavily burdened patient population.

Abstract
BACKGROUND It is important to measure the self-efficacy knowledge of the caregiver of Duchenne muscular dystrophy (DMD) patients in order to overcome the problems that arise and carry out the care process in a healthy manner. OBJECTIVE This research was carried out to develop a self-efficacy scale in caregivers of individuals with DMD. METHODS The study was conducted with 99 volunteer DMD caregivers to evaluate the psychometric properties of the developed scale. Exploratory Factor Analysis (EFA) was performed with the SPSS 25 Package Program to determine the factors of the scale. Confirmatory Factor Analysis (CFA) analysis was performed with AMOS 23 to confirm the factors obtained by EFA. Cronbach's alpha coefficient was used for the internal consistency of the DMD-CSES. RESULTS A valid and reliable scale was obtained to measure the self-efficacy of caregivers of DMD patients. CONCLUSION Although some scales have been developed to evaluate the care burden of family members who care for patient-centered symptoms and functional changes in patients with DMD, there is no single scale that adequately describes the conditions and resources of caregivers on a global scale. The search for a definitive scale is expected to continue until a definitive treatment for the disease is found. Developing a valid and reliable scale to identify the self-efficacy, knowledge, skills and resources of caregivers with a common perspective of physicians and health management team centred on patients with DMD will be effective in practice.

Abstract
Intracellular calcium dysregulation, oxidative stress, and mitochondrial dysfunction are some of the main pathway contributors towards disease progression in Duchenne muscular dystrophy (DMD). This study is aimed at investigating the effects of light emitting diode therapy (LEDT) and idebenone antioxidant treatment, applied alone or together in dystrophic primary muscle cells from mdx mice, the experimental model of DMD. Mdx primary muscle cells were submitted to LEDT and idebenone treatment and evaluated for cytotoxic effects and calcium and mitochondrial signaling pathways. LEDT and idebenone treatment showed no cytotoxic effects on the dystrophic muscle cells. Regarding the calcium pathways, after LEDT and idebenone treatment, a significant reduction in intracellular calcium content, calpain-1, calsequestrin, and sarcolipin levels, was observed. In addition, a significant reduction in oxidative stress level markers, such as H2O2, and 4-HNE levels, was observed. Regarding mitochondrial signaling pathways, a significant increase in oxidative capacity (by OCR and OXPHOS levels) was observed. In addition, the PGC-1α, SIRT-1, and PPARδ levels were significantly higher in the LEDT plus idebenone treated-dystrophic muscle cells. Together, the findings suggest that LEDT and idebenone treatment, alone or in conjunction, can modulate the calcium and mitochondrial signaling pathways, such as SLN, SERCA 1, and PGC-1α, contributing towards the improvement of the dystrophic phenotype in mdx muscle cells. In addition, data from the LEDT plus idebenone treatment showed slightly better results than those of each separate treatment in terms of SLN, OXPHOS, and SIRT-1.

Abstract
Aim: To evaluate treatment effects of eteplirsen among patients with Duchenne muscular dystrophy. Methods: Using real-world claims and electronic medical record data, this retrospective comparative analysis assessed eteplirsen-treated and control cohorts matched by age, disease progression state, and pre-index period healthcare resource utilization. Poisson regression was used to evaluate eteplirsen effects on healthcare resource utilization outcomes. Results: Eteplirsen was associated with statistically significant reductions in rates of hospital encounters (31%), emergency room visits (31%), need for pulmonary management (33%), cardiac management (21%), tracheostomy (86%), and assisted ventilation (39%) versus the control group. Other assessed outcomes favored eteplirsen numerically but did not all reach statistical significance. Conclusion: Eteplirsen-treated patients had reduced rates of multiple healthcare resource utilization measures versus matched controls.

Abstract
BACKGROUND Bardet-Biedl syndrome (BBS) is a rare, genetically heterogeneous obesity syndrome associated with hyperphagia. Given the early onset of BBS symptoms in childhood and multifaceted complications, this study aimed to quantify the caregiver burden associated with BBS. METHODS A cross-sectional, multi-country survey of caregivers from the United States (US), United Kingdom (UK), Canada, and Germany was designed to quantify the extent of caregiver burden associated with obesity and hyperphagia symptoms (i.e., uncontrollable hunger) among patients with BBS. RESULTS A total of 242 caregivers across the four countries met the inclusion criteria and completed the survey. The mean (standard deviation [SD]) age of the caregivers was 41.9 (6.7) years, and the mean (SD) age of individuals with BBS in their care was 12.0 (3.7) years. Hyperphagia contributed to a BBS diagnosis in 230 of 242 individuals (95.0%). On average, caregivers used eight different weight management approaches for those in their care and expressed a strong desire for more effective weight management methods. Based on the Impacts of Hyperphagia: Caregiver version, patients' hyperphagia had a moderate-to-severe impact on caregiver mood (56.6%), sleep (46.6%), and relationships (48.0%). Caregivers reported experiencing a high level of personal strain (mean [SD], 17.1 [2.9]) and family impact (mean [SD] score, 26.0 [3.8]) due to BBS, as measured by the Revised Impact on Family Scale. Among caregivers in the workforce, there also was high impairment in total work productivity (mean [SD], 60.9% [21.4%]) due to caring for patients with BBS according to the Work Productivity and Activity Impairment. More than half (53%) of the caregivers reported spending over 5,000 out-of-pocket in local currency for medical expenses for the patient with BBS in their care. CONCLUSIONS Obesity and hyperphagia have negative impacts on the lives of caregivers of patients with BBS. The burden is demonstrated to be multifaceted, with various components that may interact with and confound each other, including intensive weight management efforts, productivity loses, impaired family dynamics and out-of-pocket medical expenses.

Abstract
Understanding the perceptions and experiences related to the end of life (EoL) of boys and men with Duchenne muscular dystrophy from their own and/or family perspective is limited based on the available qualitative empirical studies. This systematic review was done with a thematic synthesis of qualitative evidence according to the PRISMA Statement Guidelines and the SPIDER search tool. The review included empirical, qualitative, and relevant full-text studies published in 2000-2023 in the EBSCO Discovery Service, ISI Web of Science, Scopus, PubMed, and ProQuest databases. From o total of eight included qualitative studies, four main key themes were identified: "Being a parent/caregiver" - psychosocial aspects, needs, and experiences; "Communication about EoL with healthcare and other professionals" - positive experiences and personal shortcomings; "Discussions about…" - the issue of EoL, dying and death; and "End of life" - end-of-life care, planning and the need for palliative care.

Abstract
This workshop aimed to develop recommendations for psychological interventions to support people living with slowly progressive neuromuscular disorders (NMD). The workshop comprised clinicians, researchers, people living with NMD and their relatives. First, participants considered the key psychological challenges presented by NMD and the impact of NMD on relationships and mental health. Later, several psychological approaches for enhancing well-being in NMD were described. The results of randomised controlled trials of Cognitive Behaviour Therapy and Acceptance and Commitment Therapy for improving fatigue, quality of life, and mood in adults with NMD were examined. Then the group considered ways to adapt therapies for cognitive impairments or neurodevelopmental differences that occur in some NMD, alongside ways to support children and adolescents with NMD and their family members. Based on the evidence from randomised controlled trials, carefully conducted observational studies, and the coherence of these data with the experience of those living with NMD, the group recommends that psychological interventions should be embedded in the routine clinical care offered to people living with NMD.

Abstract
Home mechanical ventilation (HMV) is a treatment for chronic respiratory failure that has shown clinical and cost effectiveness in patients with underlying COPD, obesity-related respiratory failure and neuromuscular disease (NMD). By treating chronic respiratory failure with adequate adherence to HMV, improvement in patient-reported outcomes including health-related quality of life (HRQoL) have been evaluated using general and disease-specific quantitative, semi-qualitative and qualitative methods. However, the treatment response in terms of trajectory of change in HRQoL is not uniform across the restrictive and obstructive disease groups. In this review, the effect of HMV on HRQoL across the domains of symptom perception, physical wellbeing, mental wellbeing, anxiety, depression, self-efficacy and sleep quality in stable and post-acute COPD, rapidly progressive NMD (such as amyotrophic lateral sclerosis), inherited NMD (including Duchenne muscular dystrophy) and obesity-related respiratory failure will be discussed.

Abstract
OBJECTIVE This systematic review aims to update the evidence on Duchenne muscular dystrophy (DMD) in Italy, describing the epidemiology, quality of life (QoL) of patients and caregivers, treatment adherence, and economic impact of DMD. METHODS Systematic searches were conducted in PubMed, Embase and Web of Science up to January 2023. Literature selection process, data extraction and quality assessment were performed by two independent reviewers. Study protocol was registered in PROSPERO (CRD42021245196). RESULTS Thirteen studies were included. The prevalence of DMD in the general population is 1.7-3.4 cases per 100,000, while the birth prevalence is 21.7-28.2 per 100,000 live male births. The QoL of DMD patients and caregivers is lower than that of healthy subjects, and the burden for caregivers of DMD children is higher than that of caregivers of children with other neuromuscular disorders. The compliance of real-world DMD care to clinical guidelines recommendations in Italy is lower than in other European countries. The annual cost of illness for DMD in Italy is € 35,000-46,000 per capita while, adding intangible costs, the total cost amounts to € 70,000. CONCLUSION Although it is a rare disease, DMD represents a significant burden in terms of quality of life of patients and their caregivers, and economic impact.

Abstract
PURPOSE Some parents of children with DMD find their role challenging, affecting quality of life. To inform support methods, we aimed to understand the lived experiences of parents and how these interact with disease progression. MATERIALS AND METHODS PRISMA informed protocol development. Qualitative and mixed methods studies were included. Four databases were searched and study quality was assessed using a standardised measure. Extracted data were analysed using thematic synthesis. RESULTS 26 studies were included, comprising 362 parents. Seven descriptive themes were apparent: "Diagnostic Experiences", "Coping with the Caregiver Role", "Illness Trajectory and Associated Interventions", "Family Communication", "Network of Support", "Navigating Systems" and "Transition Experiences". Four analytical themes were then derived: "The Cyclical Nature of Grief", "Lifelong Expert in the Needs and Experiences of an Individual with DMD", "Navigating Deviation from Typical Life Course" and "Uncertainty as Ever Present". CONCLUSION The extant evidence suggests that the experience of parenting a child with DMD is often characterised by: a cycle of grief that begins at diagnosis, which runs parallel to the development of expertise in caregiving; within this parents notice deviations from their child's and their own expected life course and adjust to the emotions and uncertainty that this can bring.IMPLICATIONS FOR REHABILITATIONProfessionals should be cognisant to the complex grief process associated with DMD, which occurs from diagnosis onwards.There should be continued support for parents following bereavement.Peer support groups may also offer parents ways to maintain well-being.The necessity for parents to function effectively within an uncertain context that induces challenging emotions suggests a role for psychological therapies.

Abstract
Chronic respiratory failure is a common, important complication of many types of neuromuscular and chest wall disorders. While the pathophysiology of each disease may be different, these disorders can variably affect all muscles involved in breathing, including inspiratory, expiratory, and bulbar muscles, ultimately leading to chronic respiratory failure and hypoventilation. The use of home assisted ventilation through noninvasive interfaces aims to improve the symptoms of hypoventilation, improve sleep quality, and, when possible, improve mortality. An increasing variety of interfaces has allowed for improved comfort and compliance. In a minority of scenarios, noninvasive ventilation is either not appropriate or no longer effective due to disease progression, and a transition to tracheal ventilation should be considered.

Abstract
Almost 40% of US adults provide informal caregiving, yet research gaps remain around what burdens affect informal caregivers. This study uses a novel social media site, Reddit, to mine and better understand what online communities focus on as their caregiving burdens. These forums were accessed using an application programming interface, a machine learning classifier was developed to remove low information posts, and topic modeling was applied to the corpus. An expert panel summarized the forums' themes into ten categories. The largest theme extracted from Reddit's forums discussed the personal emotional toll of being a caregiver. This was followed by logistic issues while caregiving and caring for parents who have cancer. Smaller themes included approaches to end-of-life care, physical equipment needs when caregiving, and the use of wearables or technology to help monitor care recipients. The platform often discusses caregiving for parents which may reflect the age of Reddit's users. This study confirms that Reddit forums are used for caregivers to discuss the burdens associated with their role and the types of stress that can result from informal caregiving.

Estimating Societal Cost of Illness and Patients' Quality of Life of Duchenne Muscular Dystrophy in Egypt. Value Health Reg Issues 2023; 33:10-16. [PMID: 36162195 DOI: 10.1016/j.vhri.2022.08.006] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/06/2022] [Revised: 07/16/2022] [Accepted: 08/10/2022] [Indexed: 01/12/2023]
Abstract
OBJECTIVES Duchenne muscular dystrophy (DMD) is a rare neuromuscular disease that causes substantial economic burden. This study aims to measure the DMD cost from societal perspective and the quality of life (QOL) of the Egyptian patients. METHODS We conducted interviews with caregivers of patients with DMD. The questionnaire included demographics, healthcare resource use, and nonmedical and indirect costs. Total disease burden was estimated with a bottom-up approach. QOL was measured with a disease-specific tool. Costs and utilities were stratified by the disease stage. RESULTS Caregivers of 97 patients with DMD were interviewed. The mean annual per-patient cost of $17 485 (SD ± 9240) was estimated resulting in a total burden of $138 217 043 in Egypt. Nonmedical costs made up the largest category representing 54% followed by medical then indirect costs. Informal care made the greatest contribution of nonmedical costs whereas physiotherapy was the largest medical subcategory. Nonmedical costs were highest in stage 3 and lowest at early stages whereas medical costs were almost steady among all stages with differences in individual subcategories. Of all medical costs, 95% were out of pocket. The mean utility score was 0.43 (± 0.31), which decreases with disease progression. CONCLUSION Our study quantified the huge economic burden of DMD on the society and how it differs in different stages. Almost the whole burden is paid by households resulting in catastrophic expenditures, which leads to reduced compliance and quality of care. QOL is also severely compromised. Our findings can inform future healthcare policies and economic evaluation of new DMD therapies.

Abstract
BACKGROUND Carers of people living with rare diseases report heavy burden and a plethora of unmet needs. A previous parental supportive care needs framework has described the needs of parents of children living with rare diseases, but it is not specific to rare inherited diseases (RIDs) and does not include non-parental carers. We conducted a targeted literature review to: (1) ascertain the burden/supportive care needs of informal carers of people living with RIDs, (2) understand the burden/supportive care needs unique to these carers, and (3) develop a conceptual model based on the findings. METHODS A targeted literature review searching Embase and Medline between 2000 and 2020 was conducted to identify journal articles describing the burden/supportive care needs of all types of informal carers of people living with RIDs. Thematic analysis was conducted on the articles to develop a conceptual model. RESULTS After screening and quality appraisal, 31 journal articles were analysed, representing 70 RIDs (including bleeding, bone, central nervous system, multisystem and inherited metabolic disorders). Most articles (74%) focused on parent carer samples. The conceptual model has three overarching domains, encompassing 13 themes: (1) Living with Rare Inherited Disease (Being a Carrier of Rare Disease, Carer Perceptions, Disease Severity); (2) Carer Needs/Burden (Social/Community, Well-being, Information, Practical); and (3) Carer Coping Strategies (Acceptance, Support Systems, Gratitude and Hope, Faith, Quest for Knowledge, Establish a Routine). Our conceptual model uniquely describes carers' transmission guilt, clinically relevant depression and anxiety, worry about future family members living with the RID, and challenging decisions about having more children. Carers often implemented psychological, structural, practical, and social coping strategies to manage their burdens. CONCLUSIONS The identified burdens underscore the need for the provision of information and social support to these carers. Future research should focus on the (1) potential mediators/moderators of carers' burden, (2) needs of carers within the wider family including siblings and grandparents, (3) needs of carers of adults living with RIDs, including spouses and children, and (4) biopsychosocial effect on carers living with a RID themselves. Our conceptual model offers a potential tool for healthcare professionals to utilise during the provision of support to carers.

Abstract
The X-linked inherited neuromuscular disorder Duchenne muscular dystrophy is characterised by primary abnormalities in the membrane cytoskeletal component dystrophin. The almost complete absence of the Dp427-M isoform of dystrophin in skeletal muscles renders contractile fibres more susceptible to progressive degeneration and a leaky sarcolemma membrane. This in turn results in abnormal calcium homeostasis, enhanced proteolysis and impaired excitation-contraction coupling. Biochemical and mass spectrometry-based proteomic studies of both patient biopsy specimens and genetic animal models of dystrophinopathy have demonstrated significant changes in the concentration and/or physiological function of essential calcium-regulatory proteins in dystrophin-lacking voluntary muscles. Abnormalities include dystrophinopathy-associated changes in voltage sensing receptors, calcium release channels, calcium pumps and calcium binding proteins. This review article provides an overview of the importance of the sarcolemmal dystrophin-glycoprotein complex and the wider dystrophin complexome in skeletal muscle and its linkage to depolarisation-induced calcium-release mechanisms and the excitation-contraction-relaxation cycle. Besides chronic inflammation, fat substitution and reactive myofibrosis, a major pathobiochemical hallmark of X-linked muscular dystrophy is represented by the chronic influx of calcium ions through the damaged plasmalemma in conjunction with abnormal intracellular calcium fluxes and buffering. Impaired calcium handling proteins should therefore be included in an improved biomarker signature of Duchenne muscular dystrophy.

Abstract
INTRODUCTION : Duchenne muscular dystrophy (DMD) is a progressive genetic disease characterized by muscular weakness with a global prevalence of 7.1 cases per 100,000 males. DMD is caused by mutations of the dystrophin gene on the X chromosome which is responsible for dystrophin protein production. Dystrophin is a cytoskeletal protein that contributes to structural support in muscle cells. DMD mutations result in dystrophin protein deficiency which leads to muscle damage and the associated clinical presentation. AREAS COVERED : Corticosteroids such as prednisone and deflazacort are routinely given to patients to treat inflammation, but their use is limited by the occurrence of side effects and a lack of standardized prescribing. Exon-skipping medications are emerging as treatment options for a small portion of DMD patients even though efficacy is uncertain. Many new therapeutics are under development that target inflammation, fibrosis, and dystrophin replacement. EXPERT OPINION : Because of side effects associated with corticosteroid use, there is need for better alternatives to the standard of care. Excessive cost is a barrier to patients receiving medications that have yet to have established efficacy. Additional therapies have the potential to help patients with DMD, although most are several years away from approval for patient use.

Abstract
Indigo is a bis-indolic alkaloid that has antioxidant and anti-inflammatory effects reported in literature and is a promissory compound for treating chronic inflammatory diseases. This fact prompted to investigate the effects of this alkaloid in the experimental model of Duchenne muscular dystrophy. The main aim of this study was to evaluate the potential role of the indigo on oxidative stress and related signaling pathways in primary skeletal muscle cell cultures and in the diaphragm muscle from mdx mice. The MTT and Neutral Red assays showed no indigo dose-dependent toxicities in mdx muscle cells at concentrations analyzed (3.12, 6.25, 12.50, and 25.00 μg/mL). Antioxidant effect of indigo, in mdx muscle cells and diaphragm muscle, was demonstrated by reduction in 4-HNE content, H2O2 levels, DHE reaction, and lipofuscin granules. A significant decrease in the inflammatory process was identified by a reduction on TNF and NF-κB levels, on inflammatory area, and on macrophage infiltration in the dystrophic sample, after indigo treatment. Upregulation of PGC-1α and SIRT1 in dystrophic muscle cells treated with indigo was also observed. These results suggest the potential of indigo as a therapeutic agent for muscular dystrophy, through their action anti-inflammatory, antioxidant, and modulator of SIRT1/PGC-1α pathway.

Abstract
Background: Clinical medical management guidelines of Duchenne muscular dystrophy (DMD) emphasize prevention and early identification and treatment. Objective: The objective of our study was to review, synthesize, and grade published evidence of the impact of the timing of clinical interventions in DMD. Methods: We searched PubMed, Embase, and the Cochrane Library for records published from inception up until November 19, 2021, reporting evidence of the impact of the timing of clinical interventions in DMD. We assessed the quality of evidence using the Grading of Recommendations, Assessment, Development and Evaluations (GRADE) framework. Results: We included 12 publications encompassing 1,623 patients with DMD from seven countries (Australia, France, Germany, Italy, Japan, the United Kingdom, and the United States of America). Six (50%) studies reported evidence of an impact of the timing of initiation of glucocorticoids on loss of ambulation, cardiomyopathy, fractures, forced vital capacity, and height and BMI; four (33%) of cardiac medication (i.e., angiotensin-converting enzyme inhibitors, β-blockers, and eplerenone) on left ventricular size and function and survival; one (8%) of lower limb surgery on motor quotient and loss of ambulation; and one (8%) of ataluren on lower extremity and motor function. The overall quality of the body of evidence was low. Conclusion: While there is a clinical rationale for anticipatory diagnostic and therapeutic strategies, evidence of the impact of the timing of initiation of treatments in patients with DMD is still emerging. Further research of this topic is warranted to inform treatment guidelines in this indication.

Abstract
Introduction Duchenne muscular dystrophy is a rare, progressive, life-limiting genetic neuromuscular condition that significantly impacts the quality of life of informal caregivers. Carer quality of life is measured using heterogeneous self-report scales, yet their suitability for Duchenne remains unclear. This review aimed to identify and evaluate the reliability and validity of quality of life instruments in Duchenne carers. Materials and methods Systematic searches were conducted in Embase, MEDLINE, CINAHL, PsycINFO, Cochrane Library and Google Scholar. Full research articles reporting data on multiple-item self-report quality of life instruments in informal Duchenne carers were included. Extracted evidence was qualitatively synthesised and evaluated, including risk of bias, against the Consensus-based Standards for the selection of health Measurement Instruments. Duchenne carer collaborators (N = 17) helped rate the instruments’ content validity. Results Thirty-one articles featuring thirty-two quality of life instruments were included. Content validity was rated as “inconsistent” based on very low quality evidence. For Duchenne carer collaborators, the best instrument was PedsQL Family Impact Module. Only one instrument had evidence for structural validity (rated “unsatisfactory”) and measurement invariance (rated “satisfactory”). Instruments received “satisfactory” ratings for internal consistency and mixed ratings for construct validity and responsiveness. There was no evidence for reliability, measurement error, or criterion validity. Discussion Instruments used to measure Duchenne carer quality of life have limited and often inconsistent supportive psychometric evidence. Further work must investigate instruments’ measurement properties in Duchenne carers and/or the development of new tools. In the interim, we recommend considering the PedsQL Family Impact Module based on Duchenne carer ratings.

Abstract
Background Providing caregiving support to people with Duchenne muscular dystrophy (DMD) is challenging, beginning in early childhood, and continuing through the progression of multidimensional disability. This study addressed the interplay between caregiver impact, out-of-pocket expenditures, and DMD disability. To examine these interconnections, we investigated the association between caregiver impact domains and out-of-pocket expenditures; and the presence of clusters in caregivers on the basis of DMD-related disability domains in the patients for whom they provided caregiving support. Methods This web-based study recruited 566 DMD caregivers (140 males, 426 females; mean age 41.6 years, SD 8.8, range 21–72), examining caregiver impact using the DMD Caregiver Impact Measure, PROMIS-derived parent-proxy (PPP) measures of their child’s disability, and items tapping out-of-pocket expenditures related to home and vehicle accommodations and assistive devices. T-tests compared caregiver impact scores by out-of-pocket expenditures incurred. Latent Profile Analyses (LPA) were conducted to generate impact profiles related to child’s disability as reported by caregiver proxies. Results Higher out-of-pocket expenditures were generally associated with worse impact on the subscales, but several expenditures (e.g., kitchen, bathroom, scooter) were associated with lower impact. LPA indicated that the four-group solution provided the best relative fit and yielded good profile separation (entropy = 0.91). Caregivers with lowest impact reported the highest mobility, cognitive, and upper extremity functioning of their DMD care recipients, whereas the highest caregiver impact was driven by their care recipient’s negative affect and fatigue. The upper-middle impact group showed great variability in proxy-disability domains, whereas the lower-middle group had similar levels of disability across domains. Profiles were represented across all child ages. Conclusion Out-of-pocket expenditures were often associated with worse caregiver impact, but some associated with milder impact (i.e., bathroom or kitchen modification, investing in a ceiling lift or medical scooter). While their son’s level of disability and age were related to impact on the DMD caregiver, the domains giving rise to highest caregiver impact were not the most visible aspects of disability, such as mobility, but rather negative affect and fatigue. Other contextual attributes are likely implicated, and will be addressed in the companion paper.

Abstract
BACKGROUND To describe the reduced health-related quality of life (HRQoL) of duchenne muscular dystrophy (DMD) patients and their caregiver burden and to present its relationship with disease progression. METHODS This cross-sectional study assessed patient HRQoL with the 3-level version of the EuroQol-5D (EQ-5D-3L) and caregiver burden with the Work Productivity and Activity Impairment: General Health questionnaire. DMD patients and their caregivers were identified through Portuguese Neuromuscular Association (APN). RESULTS A total of 46 DMD main caregivers, of eight ambulant and 38 non-ambulant patients, completed the questionnaires. Over half (58.7%) of all non-ambulant patients were on ventilation support, either full-time (15.2%) or non full-time (43.5%). Non-ambulant patients had a lower mean utility scores than ambulant patients (- 0.05 versus 0.51, p value < 0.001). Caregivers of non-ambulant patients reported a significant mean daily activity impairment as compared to caregivers of ambulant patients (68% versus 23%, p value < 0.001). Among non-ambulant patients, both utility scores and caregiver impairment appeared to deteriorate according to a higher need for ventilation support, however, these results were not statistically significant. CONCLUSIONS These results emphasise the significant negative impact that DMD progression has on the patient HRQoL, as well as caregivers' ability to conduct their daily activities. Therapeutic options that stop or slow the disease progression could have a beneficial impact for both patients and caregivers.

Abstract
OBJECTIVE The objective of this study was to assess the face validity of a disease model evaluating the cost-effectiveness of ataluren for the treatment of nonsense mutation Duchenne muscular dystrophy (nmDMD). METHODS This was a Delphi panel study comprising of physicians with first-hand experience of ataluren for the treatment of nmDMD. Consensus was sought for previously unvalidated model data, including patient health status and quality of life measured using the Health Utility Index (HUI), mortality, informal caregiving, and the expected benefit of early ataluren treatment across four states: (1) ambulatory, (2) non-ambulatory, not yet requiring ventilation support, (3) non-ambulatory, night-time ventilation support, and (4) non-ambulatory, full-time ventilation support. RESULTS Nine experts from five countries participated in the Delphi panel. Consensus was obtained for all questions after three panel rounds (except for two HUI-questions concerning hand function [dexterity]). Consensus HUI-derived utilities for state (1) were 1.0000 for ataluren on top of best supportive care (BSC) and 0.7337 for BSC alone. Corresponding estimates for state (2) were 0.3179 and 0.2672, for state (3) 0.1643 and 0.0913, and for state (4) -0.0732 and -0.1163. Consensus mortality rates for states (1), (2), and (3) were 4%, 13%, and 33%, and life expectancy in state (4) was agreed to be 3 years. Panelists further agreed that two informal caregivers typically provide day-to-day care/support to patients with nmDMD, and that starting treatment with ataluren at 2 versus 5 years of age would be expected to delay loss of ambulation by an additional 2 years, and initiation of night-time and full-time ventilation support by an additional 3 years, respectively. LIMITATIONS The main limitation concerns the size of the Delphi panel, govern primarily by the rarity of the disease. CONCLUSION This study confirms the face validity of key clinical parameters and assumptions underlying the ataluren cost-effectiveness model.

[PMID: 34924347 DOI: 10.1016/j.sleh.2021.11.003] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/28/2020] [Revised: 10/29/2021] [Accepted: 11/04/2021] [Indexed: 11/28/2022]
Abstract
BACKGROUND The sleep health of caregivers of children with Duchenne muscular dystrophy (DMD) is often overlooked in clinical practice and research. This study characterizes the sleep health of caregivers of children with DMD (4-17 years) compared to parents of age-matched, unaffected children. We explore potential contributors to parental sleep efficiency and hypothesize that child awakenings will have a considerable influence on parental sleep efficiency. METHODS In this observational study, parents and their children were asked to wear the ActiGraph GT9X Link at night for 1 month. From these data, actigraphy variables (eg, percent sleep efficiency, nocturnal awakenings) were calculated and averaged for parents and children. We also used the Pittsburgh Sleep Quality Index (PSQI) to measure subjective sleep quality. MAIN FINDINGS Parents in the DMD group (n = 25, M = 84.5%) had significantly worse sleep efficiency compared to controls (n = 15, M = 87.8%, p = .048). This difference was sustained after controlling for parent age, child age, and average child awakenings (F(4, 23) = 2.68, p= .057, R2 = .32). Additionally, more parents in the DMD group scored as "poor sleepers" on the PSQI (above 5, 50%) compared to controls (23%), suggesting a strong, yet not statistically significant association between subjective poor sleep and group (χ2(1) = 2.47, p = .116, OR = 3.33). CONCLUSION Parents of children with DMD exhibit both objective and subjective differences suggesting their sleep is impaired. Interestingly, these sleep concerns are not significantly explained by child awakenings as hypothesized. Future research is needed to fully understand the prevalence and cause of poor sleep in a larger group of DMD caregivers as well as direct care for caregivers of children with disabilities.

Abstract
Background This study examined the impact of Duchenne muscular dystrophy (DMD) on family-member caregivers in terms of quality of life, life stress, and indirect costs, as compared to a stratified comparison group of parents of similar-age children without DMD. Methods A web-based survey included DMD caregivers and a nationally representative comparison group of parents of children without DMD stratified by Child Age Group. Outcomes included quality of life, resilience, caregiver impact, stressful life events, financial strain, out-of-pocket expenditures, work productivity and unrealized ambitions. General linear models assessed the main effect of Caregiver Group and the interaction of Caregiver Group with Child-Age-Group, after adjusting for demographic covariates. Results Compared to parents without a DMD child, DMD Caregivers reported better physical health but worse mental health, positive affect/well-being, environmental mastery, difficulty paying bills, and more hours missed from work. Providing caregiving support for DMD teenagers was the most challenging. DMD caregivers curtailed their educational and professional ambitions, and modified their homes to accommodate the disability associated with DMD. Their non-DMD children had to make sacrifices as well. Nonetheless, in resilience and life stress, DMD caregivers were comparable to the comparison group, and showed consistent levels of positive emotions across the age of their DMD child. Conclusion DMD caregivers fared worse on most outcomes and faced more hurdles in work life. They face constraints and hidden costs that impact their health and financial well-being. Caregivers of teenagers with DMD reported higher impact. Nonetheless, parents of DMD children of all ages maintained notable resilience and positivity.

Abstract
PURPOSE Children born with Complex Life-Threatening Conditions (CLTCs) often require complex and specialized services. Parents of children with CLTCs balance the role of caregiver with other responsibilities of employment, education, relationships, and self-care. The purpose of this paper is to describe the challenges for parents serving as caregivers of children with CLTCs and their intersection with health care provider expectations through utilization and adaptation of the role theory framework. DESIGN/METHODS We employed a qualitative descriptive design, secondary analysis of a longitudinal study on parent and provider decision making for children with CLTC. There were 218 interviews from sixty-one parents of 35 infants with prematurity, bone marrow transplant, and/or complex cardiac disease, followed for one year unless death occurred. Content analysis and thematic generation were performed capturing the various parental roles embedded within provider expectations of informal parental caregiving. RESULTS Results showed that parents of children with CLTCs serve multidimensional roles, including that of informal nurse and care coordinator, while maintaining additional personal roles as parent and family provider. Parents experienced challenges as caregivers that were shaped by perceived expectations of health care providers as well as lack of support, often leading to role strain, conflict, overload, and sometimes exit. CONCLUSIONS Parents of children with CLTCs experience both common and unique challenges inn balancing multiple roles as an informal caregiver. Despite utilizing positive coping mechanisms, their status as parent caregiver carries significant risk for role strain and overload. We recommend the implementation of strategies for increasing parental support and family-centered care.

Abstract
INTRODUCTION/AIMS Duchenne and Becker muscular dystrophies (DBMD) are X-linked neuromuscular disorders characterized by progressive muscle weakness, leading to decreased mobility and multisystem complications. We estimate productivity costs attributable to time spent by a parent caring for a male child under the age of 18 y with DBMD, with particular focus on female caregivers of boys with Duchenne muscular dystrophy (DMD) who have already lost ambulation. METHODS Primary caregivers of males with DBMD in the Muscular Dystrophy Surveillance and Research Tracking Network (MD STARnet) were surveyed during 2011-2012 on family quality of life measures, including labor market outcomes. Of 211 respondents, 96 female caregivers of boys with DBMD were matched on state, year of survey, respondent's age, child's age, and number of minor children with controls constructed from Current Population Survey extracts. Regression analysis was used to estimate labor market outcomes and productivity costs. RESULTS Caregivers of boys with DBMD worked 296 h less per year on average than caregivers of unaffected children, translating to a $8816 earnings loss in 2020 U.S. dollars. Caregivers of boys with DMD with ≥4 y of ambulation loss had a predicted loss in annualized earnings of $23,995, whereas caregivers of boys with DBMD of the same ages who remained ambulatory had no loss of earnings. DISCUSSION Female caregivers of non-ambulatory boys with DMD face additional household budget constraints through income loss. Failure to include informal care costs in economic studies could understate the societal cost-effectiveness of strategies for managing DMD that might prolong ambulation.

Abstract
Purpose: To describe and explore carer quality of life (QoL) and night-time attendance to their child in parents of non-ambulant youth with Neuromuscular Disorders.Methods: A cross-sectional population-based, comprehensive survey including the Adult Carer QoL (AC-QoL) questionnaire, measures of social context and youths' physical status. Associations between carer-QoL or frequency of parents' night-time attendance with independent variables were explored using linear and logistic regression models, respectively.Results: Parents' perceived lower carer-QoL (mean 76.5/120, SD 18.5) when they attended to their child twice a night or more (n = 17/35) and with shorter time since their child was prescribed noninvasive ventilation (NIV). Parental night-time attendance was not associated with youth's actual use of NIV, but was more likely when youth required assistance to turn in bed, reported frequent sleep discomfort and had more severe joint contractures.Conclusions: To optimize parent carer-QoL, interventions must address parents' frequency of night-time attendance and youths' sleep comfort.

Abstract
PURPOSE Informal caregivers provide ongoing assistance to a loved one with a health condition. No studies have compared caregiving intensity and perception of burden across chronic medical conditions. MATERIALS AND METHODS Databases were searched from inception through 11 September 2020 to identify studies that included the Level of Care Index or the Zarit Burden Inventory (ZBI) among caregivers for people with chronic diseases. Pooled mean ZBI scores and 95% confidence intervals by medical condition were calculated using a random effects model and heterogeneity with I2. RESULTS Ninety-seven included articles reported on 98 unique samples across 21 chronic diseases. No study used the Level of Care Index. Among 12 disease groups with more than one study, heterogeneity was too high (I2 range: 0-99.6%, ≥76.5% in 11 groups) to confidently estimate burden. The percent of studies rated high risk of bias ranged from 0% to 98%, but all external validity items were rated as high-risk in >50% of studies. CONCLUSIONS Findings highlight the need for studies on caregiver burden to improve sampling techniques; better report sampling procedures and caregiver and care recipient characteristics; and develop a standard set of outcomes, including a measure of caregiving intensity. Systematic Review Registration: CRD42017080962IMPLICATIONS FOR REHABILITATIONThe amount of burden reported by caregivers to loved ones is associated with reduced physical and mental health.We found considerable heterogeneity in perceived burden reported by informal caregivers across different studies within disease groups, which is likely related to methodological issues, including sampling techniques.Health care providers who use research on caregiver burden should assess how representative study samples may be and exercise caution in drawing conclusions.

Abstract
Background Duchenne muscular dystrophy is a rare genetic neuromuscular disorder, which can result in early death due to disease progression. Ataluren is indicated for the treatment of nonsense mutation Duchenne muscular dystrophy, in ambulatory individuals aged two years and older. This study explored the impact of caring for an ambulatory individual with nonsense mutation Duchenne muscular dystrophy, as well as the impact of treatment with ataluren on the caregiver experience, using retrospective recall. Methods Qualitative interviews were conducted with caregivers in the UK. Interviews were conducted by telephone, were recorded and transcribed. Data were analysed using thematic analysis and saturation was recorded. Results Ten interviews were conducted with parents of individuals aged 4–19 years. Caregivers reported proximal impacts (physical, emotional, time-related), and distal impacts (work, relationships, social life) of caring for their sons. The relationships between these impacts were illustrated in a conceptual model. Changes to the caregiver experience since initiation with their son’s treatment were discussed. Conclusion Caring for an ambulatory individual with nonsense mutation Duchenne muscular dystrophy has a substantial multifaceted impact on caregivers. Treatments which have the potential to improve symptoms or delay progression, may also have a positive impact on the quality of life of caregivers.

Abstract
The health-related quality of life and emotional distress among mothers of sons with Duchenne or Becker muscular dystrophies (n = 82) were compared to sex- and age group-matched controls (n = 26). Participants self-reported health-related quality of life for themselves and their son(s), emotional distress, and mood/anxiety-related medication. Mothers reported poorer health-related quality of life across all domains of their health-related quality of life, as well as higher levels of emotional distress. Clinically elevated symptoms of anxiety were reported by 39% of mothers. Mothers' report of poorer health-related quality of life for their son(s) was a significant predictor of worse health-related quality of life and emotional distress for themselves across most domains. Additionally, older age of mothers predicted greater energy/less fatigue and lower levels of anxiety. Results highlight the need for screening emotional distress among mothers, as well as consideration for accessible interventions to improve the psychosocial functioning among these families.

Abstract
There are growing numbers of adults with Duchenne Muscular Dystrophy living well into their fourth decade. These patients have complex medical needs that to date have not been addressed in the International standards of care. We sought to create a consensus based standard of care through a series of multi-disciplinary workshops with specialists from a wide range of clinical areas: Neurology, Cardiology, Respiratory Medicine, Gastroenterology, Endocrinology, Palliative Care Medicine, Rehabilitation, Renal, Anaesthetics and Clinical Psychology. Detailed reports of evidence reviewed and the consensus building process were produced following each workshop and condensed into this final document which was approved by all members of the Adult North Star Network including service users. The aim of this document is to provide a framework to improve clinical services and multi-disciplinary care for adults living with Duchenne Muscular Dystrophy.

Smith J, Damm K, Hover G, Chien J. Lessons from an Experiential Approach to Patient Community Engagement in Rare Disease. Clin Ther 2020; 43:421-429. [PMID: 33375998 DOI: 10.1016/j.clinthera.2020.12.002] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/02/2020] [Revised: 12/01/2020] [Accepted: 12/06/2020] [Indexed: 01/09/2023]
Abstract
Meaningful engagement between biopharmaceutical companies and patient communities has increasingly become an important part of the therapeutic-development process, as such engagement improves the understanding of the multifaceted challenges and unmet needs that communities experience and provides an opportunity to inform the approach to the development of new therapies and services. Presented here are learnings from a community-advisor program designed to engage families of patients with Duchenne muscular dystrophy (DMD) in a manner that enabled caregivers to make valuable contributions to the therapeutic-development process and to the DMD community. Parents of children with DMD, representing the broader DMD community, were identified in partnership with patient-advocacy organizations and invited to participate in a community-advisor meeting with members of Wave Life Sciences. The community-advisor meeting was designed to provide participants with an opportunity to share their personal experiences with DMD, to help to inform the therapeutic-development process, and to identify potential solutions for addressing unmet needs. Three community-advisor meetings were held with a total of 30 parents, representing 36 children with DMD. Key themes that emerged from the advisors' discussion included the importance of the community's emotional and mental support, the inconsistencies in DMD care, the increased challenges and disparities faced by underserved communities, and the need for more comprehensive, holistic approaches to the treatment and management of DMD. The advisors viewed the meetings as an opportunity to share their voices with a biopharmaceutical company, coupled with the advantage of meeting other families living with similar challenges. Most of the advisors stated that this was their first advisor meeting. This community-focused approach empowered participants to voice their needs and perspectives, to brainstorm potential solutions for addressing those needs, and to initiate and foster connections in ways that had a considerable impact on one another and on therapeutic-development programs at Wave Life Sciences.

Tasks and interfaces in primary and specialized palliative care for Duchenne muscular dystrophy - A patients' perspective. Neuromuscul Disord 2020; 30:975-985.

Abstract
In spite of the improvements in care and the emergence of disease-modifying treatments, Duchenne muscular dystrophy (DMD) remains a life-limiting disease of adolescence and (young) adulthood. Palliative care approaches and principles should be integrated from the point of diagnosis and implemented throughout the lifespan. A nationwide cross-sectional survey based on a mixed-method-design of qualitative and quantitative research approaches evaluated the structural implementation and perception of palliative care for DMD in Germany. Data analyses revealed that palliative care was predominantly provided at the primary care level by pediatricians, general practitioners and specialized multi-professional outpatient structures. The majority of patients did not utilize the scopes of specialized palliative structures. Simultaneously, insufficiently treated complex symptoms, emergent and elective hospitalizations and barriers in transitioning into adult care presented a considerable burden. A collaborative integrated model with a close cooperation of patients, families and care providers is proposed involving task areas and interfaces complementing primary and specialized palliative care (1) management of complex symptoms, (2) crisis support, (3) intermittent relief of the strain for caregivers, (4) coordination of care, (5) advance care planning and (6) end-of-life care. Specialized palliative care should be used as an "add-on" approach in time of need rather than as a prognosis or disease stage.

Abstract
OBJECTIVE The aim of this study was to use a structured questionnaire in a large cohort of Duchenne Muscular Dystrophy (DMD) patients to assess caregivers and patients views on respiratory function and to establish if their responses were related to the patients' age or level of functional impairment. METHODS Questionnaires were administered to caregivers in 205 DMD patients of age between 3 and 36 years (115 ambulant, 90 non-ambulant), and to 64 DMD patients (3 ambulant, 61 non-ambulant) older than 18 years, subdivided into groups according to age, FVC, ambulatory and ventilatory status. RESULTS Some differences were found in relation to FVC % values (p = 0.014), ambulatory (p = 0.043) and ventilatory status (p = 0.014). Nearly half of the caregivers expected deterioration over the next years, with the perspective of deterioration more often reported by caregivers of non-ambulant (p = 0.018) and ventilated patients (p = 0.004). Caregivers appeared to be aware of the relevance of respiratory function on quality of life (84%) showing willingness to enter possible clinical trials if these were aiming to stabilize the progression of respiratory function with a very high number of positive responses across the spectrum of age, FVC, ambulatory and ventilatory status. The boys older than 18 years showed similar results. CONCLUSIONS Our study showed that the concern for respiratory function increases with age and with the reduction of FVC or the need for ventilation, but the need for intervention was acknowledged across the whole spectrum of age and functional status.

Abstract
Recently, progress has been observed in the knowledge about Duchenne Muscular Dystrophy (DMD), which is a severe and commonly diagnosed genetic myopathy in childhood, historically resulting in early death. Currently, there are a lot of methods available to improve the clinical course of DMD and extend patients’ life expectancy to more than 30 years of age. The key issue for DMD patients is the period between 16–18 years of age, which is described as a transition from pediatric- to adult-oriented healthcare. Adolescents and adults with DMD have highly complex healthcare needs associated with long-term steroid usage, orthopedic, ventilation, cardiac, and gastrointestinal problems. The current paper provides a comprehensive overview of special healthcare needs related to the transfer of a patient with DMD from child-oriented to adult-oriented care. Additionally, the need to organize effective care for adults with DMD is presented.

Abstract
PURPOSE To investigate the effect of caregiver burden, resilience, and quality of life of the parents of patients who are followed-up in a tertiary pediatric rehabilitation clinic. DESIGN AND METHODS This is a correlational cross-sectional study. Parents of patients who attend to utilize pediatric rehabilitation outpatient clinics of a tertiary center on a regular basis were invited to participate. All participants filled in the Zarit Caregiver Burden (ZCB) scale, Family Resilience scale (FRS) and Nottingham Health Profile (NHP). RESULTS A total of 107 patient and caregiver dyads were included. Fifty-five (51%) patients had cerebral palsy, 10 (9%) had spina bifida and 42 (39%) had other neurodevelopmental disorders. Eighty-one (75%) of the caregivers were mothers. There was a significant difference in the caregiver burden between ambulatory children (Mean ZCB score 30.11 ± 13.56) and non-ambulatory patients (Mean ZCB score 37.22 ± 13.91) (p = .01). There were moderate negative correlations between caregiver burden and FRS commitment to life and FRS self-sufficiency subscales. Caregiver burden significantly positively correlated with all NHP domains. CONCLUSIONS Caregiver burden is significantly higher in parents of non-ambulatory children when compared to ambulatory children in the pediatric rehabilitation setting. Caregiver burden and resilience correlated on moderate levels, but the factors influencing them are still unclear. PRACTICE IMPLICATIONS Healthcare and social support should be given to all caregivers in pediatric rehabilitation setting, but more so to the caregivers of non-ambulatory patients.

Life expectancy at birth in Duchenne muscular dystrophy: a systematic review and meta-analysis. Eur J Epidemiol 2020; 35:643-653. [PMID: 32107739 PMCID: PMC7387367 DOI: 10.1007/s10654-020-00613-8] [Citation(s) in RCA: 109] [Impact Index Per Article: 27.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/01/2019] [Accepted: 02/05/2020] [Indexed: 12/29/2022]
Abstract
Several studies indicate that prognosis for survival in Duchenne muscular dystrophy (DMD) has improved in recent decades. However, published evidence is inconclusive and some estimates may be obsolete due to improvements in standards of care, in particular the routine use of mechanical ventilatory support in advanced stages of the disease. In this systematic review and meta-analysis (PROSPERO identifier: CRD42019121800), we searched MEDLINE (through PubMed), CINAHL, Embase, PsycINFO, and Web of Science for studies published from inception up until December 31, 2018, reporting results of life expectancy in DMD. We pooled median survival estimates from individual studies using the median of medians, and weighted median of medians, methods. Risk of bias was established with the Newcastle–Ottawa Scale. Results were stratified by ventilatory support and risk of bias. We identified 15 publications involving 2662 patients from 12 countries from all inhabited continents except Africa. Median life expectancy without ventilatory support ranged between 14.4 and 27.0 years (pooled median: 19.0 years, 95% CI 18.0–20.9; weighted pooled median: 19.4 years, 18.2–20.1). Median life expectancy with ventilatory support, introduced in most settings in the 1990s, ranged between 21.0 and 39.6 years (pooled median: 29.9 years, 26.5–30.8; weighted pooled median: 31.8 years, 29.3–36.2). Risk of bias had little impact on pooled results. In conclusion, median life expectancy at birth in DMD seems to have improved considerably during the last decades. With current standards of care, many patients with DMD can now expect to live into their fourth decade of life.
