Increased levels of interleukin-6 exacerbate the dystrophic phenotype in mdx mice

Duchenne muscular dystrophy (DMD) is characterized by progressive lethal muscle degeneration and chronic inflammatory response. The mdx mouse strain has served as the animal model for human DMD. However, while DMD patients undergo extensive necrosis, the affected muscles of adult mdx mice rapidly regenerates and regains structural and functional integrity. The basis for the mild effects observed in mice compared with the lethal consequences in humans remains unknown. In this study, we provide evidence that interleukin-6 (IL-6) is causally linked to the pathogenesis of muscular dystrophy. We report that forced expression of IL-6, in the adult mdx mice, recapitulates the severe phenotypic characteristics of DMD in humans. Increased levels of IL-6 exacerbate the dystrophic muscle phenotype, sustaining inflammatory response and repeated cycles of muscle degeneration and regeneration, leading to exhaustion of satellite cells. The mdx/IL6 mouse closely approximates the human disease and more faithfully recapitulates the disease progression in humans. This study promises to significantly advance our understanding of the pathogenic mechanisms that lead to DMD

Use of Telemedicine Healthcare Systems in Pediatric Assistance at Territorial Level: Consensus Document of the Italian Society of Telemedicine (SIT), of the Italian Society of Preventive and Social Pediatrics (SIPPS), of the Italian Society of Pediatric Primary Care (SICuPP), of the Italian Federation of Pediatric Doctors (FIMP) and of the Syndicate of Family Pediatrician Doctors (SIMPeF)

Technological innovation can contribute to a reorganization of healthcare, particularly by supporting the shift in the focus of care from the hospital to the territory, through innovative citizen-centered models, and facilitating access to services in the territory. Health and social care delivery modalities, enabled by telemedicine, are crucial in this regard. The objective of this Consensus document, written by the main Italian Scientific Societies involved in the use of telemedicine in pediatrics, is to define a standard for its use at the territorial level in various declinations in the pediatric field; this paper also identifies priority areas for its application and the types of services that most require intervention and investment. The changes that are underway in digital transformation in all sectors are unstoppable, and for the digital transformation to take place in a productive sense, the contribution of not only all health professionals, but also of patients, is necessary. From this perspective, authors from different backgrounds were involved in the drafting of this Consensus and, in the future, other figures, primarily patients, are expected to be involved. In fact, this belongs to the vision of connected care, in which the citizen/patient actively participates in the treatment path so that they are assisted in a personalized, predictive and preventive way. The future scenario must be able to provide for the involvement of patients from the initial stages of planning any treatment path, even in the pediatric age, and increasing, where possible, the proximity of the health service to the families

Information and Training on the Use of Telemedicine in Pediatric Population: Consensus Document of the Italian Society of Telemedicine (SIT), of the Italian Society of Preventive and Social Pediatrics (SIPPS), of the Italian Society of Pediatric Primary Care (SICuPP), of the Italian Federation of Pediatric Doctors (FIMP), and of the Syndicate of Family Pediatrician Doctors (SIMPeF)

Telemedicine has entered the daily lives of doctors, although the digital skills of healthcare professionals still remain a goal to be achieved. For the purpose of a large-scale development of telemedicine, it is necessary to create trust in the services it can offer and to favor their acceptance by healthcare professionals and patients. In this context, information for the patient regarding the use of telemedicine, the benefits that can be derived from it, and the training of healthcare professionals and patients for the use of new technologies are fundamental aspects. This consensus document is a commentary that has the aim of defining the information on and training aspects of telemedicine for pediatric patients and their caregivers, as well as pediatricians and other health professionals who deal with minors. For the present and the future of digital healthcare, there is a need for a growth in the skills of professionals and a lifelong learning approach throughout the professional life. Therefore, information and training actions are important to guarantee the necessary professionalism and knowledge of the tools, as well as a good understanding of the interactive context in which they are used. Furthermore, medical skills can also be integrated with the skills of various professionals (engineers, physicists, statisticians, and mathematicians) to birth a new category of health professionals responsible for building new semiotics, identifying criteria for predictive models to be integrated into clinical practice, standardizing clinical and research databases, and defining the boundaries of social networks and new communication technologies within health services

Use of Telemedicine Healthcare Systems in Children and Adolescents with Chronic Disease or in Transition Stages of Life: Consensus Document of the Italian Society of Telemedicine (SIT), of the Italian Society of Preventive and Social Pediatrics (SIPPS), of the Italian Society of Pediatric Primary Care (SICuPP), of the Italian Federation of Pediatric Doctors (FIMP) and of the Syndicate of Family Pediatrician Doctors (SIMPeF)

: Telemedicine is considered an excellent tool to support the daily and traditional practice of the health profession, especially when referring to the care and management of chronic patients. In a panorama in which chronic pathologies with childhood onset are constantly increasing and the improvement of treatments has allowed survival for them into adulthood, telemedicine and remote assistance are today considered effective and convenient solutions both for the chronic patient, who thus receives personalized and timely assistance, and for the doctors, who reduce the need for direct intervention, hospitalizations and consequent management costs. This Consensus document, written by the main Italian Scientific Societies involved in the use of telemedicine in pediatrics, has the objectives to propose an organizational model based on the relationships between the actors who participate in the provision of a telemedicine service aimed at minors with chronic pathologies, identifying specific project links between the areas of telemedicine in the developmental age from the first 1000 days of life to the age adult. The future scenario will have to be able to integrate digital innovation in order to offer the best care to patients and citizens. It will have to be able to provide the involvement of patients from the very beginning of the design of any care pathway, increasing where possible the proximity of the health service to citizens

Looking for the best strategy to treat children with new onset juvenile idiopathic arthritis: presentation of the "comparison of STep-up and step-down therapeutic strategies in childhood ARthritiS" (STARS) trial

Background: Although a satisfactory disease control is nowadays achievable in most patients with JIA, a substantial proportion of them still do not respond adequately or reach long-term drug-free remission. According to current recommendations, treatment should be escalated in subsequent steps. A different approach is based on the assumption that the initial start of an aggressive therapy may take advantage of the "window of opportunity" and could alter the biology of the disease, leading to an improvement of long-term outcomes, including the prevention of cumulative joint damage. Objectives: This randomised clinical trial aims to compare the effectiveness of a conventional therapeutic regimen, based on treatment escalation and driven by the treat-to-target approach, with that of an early aggressive intervention based on the initial start of a combination of conventional and biological DMARDs. Methods: JIA patients with oligoarthritis or RF negative polyarthritis aged more than 2 years and with less than 4 months of disease course will be included in the study. Children will be randomised into two arms: patients in Step-up arm with less severe oligoarthritis will undergo an intra-articular corticosteroid injection (IACI) in all affected joints; patients with polyarthritis or severe oligoarthritis will receive IACI and methotrexate. Subsequent treatment will follow a standardised protocol based on the patients' level of disease activity measured with the JADAS, according to a treat-to-target strategy. Patients in Step-down arm will receive a 6-month early combined treatment (methotrexate plus IACI for less severe oligoarthritis, methotrexate plus etanercept for severe oligoarthritis and polyarthritis). The primary endpoint is the frequency of achievement of the status of clinical remission (i.e. persistence of inactive disease for at least 6 months) at the 12-month visit. Safety events, physician-centred measures and parent/patient-reported outcomes will be collected through the Paediatric Rheumatology International Trials Organisation on line database. Expected results: The STARS trial aims to provide important evidence supporting the first-line treatment choices in the care of children with oligoarticular and polyarticular JIA. If the superiority of an early aggressive therapy will be demonstrated, this will demand further studies on the biological definition of the window of opportunity for JIA. Trial registration: The Trial is registered on the ClinicalTrials.gov registry (NCT03728478) on the 31st October 2018 and EU Clinical Trials Register on the 14th May 2018 (EudraCT Number: 2018-001931-27)
