Mega scientific conferences increasingly suffer from the need for short and poster presentations without discussion. An alternative is to organize workshops in hotels large enough to accommodate all participants. This significantly increases the opportunities for constructive discussion during breakfasts, lunches, dinners and long evenings that can bring together experts of scientific and clinical sub-specialties and young fellows. Time for groups' discussions and new collaborations are increased so as the job opportunities for the young researchers. The Padova Muscle Days have offered in the previous thirty-five years these opportunities, which have matured into innovative and multidisciplinary results to the point that it came naturally to underline it with a neologism now included in the title of the 2025 event: "Mobility Medicine", a discipline not yet officially recognised, that makes explicit the call for rejoining knowledges dispersed in sub-specialisations. The included program of the Padua Days on Muscle and Mobility Medicine 2025 (2025Pdm3) will be hosted at the Hotel Petrarca in Euganean Thermae (Padua, Italy) from 25 to 29 March 2025. It further testifies by listing unique Sessions that it is possible to organize valid countermeasures to the inevitable tendencies towards hyperspecialization that the explosive increase in scientific progress brings with it. Furthermore, the European Journal of Translational Myology and Mobility Medicine (Ejtm3) will accept typescripts on results presented at the 2025Pdm3, together with the Special Section: New Trends in Musculoskeletal Imaging of the MDPI (Basel) Journal Diagnostics, because diagnosis is essential to prevent, manage and follow-up not only neuro-metabolic-muscular disorders, but the unavoidable physiologicical decay of performances in early and late aging. Hoping many others share our dreams, we look forward to meeting you at 2025Pdm3 conference.

Reconstruction of the Anterior Cruciate Ligament (ACL) in Skeletally Immature Patients (SIP) poses challenges due to anatomical and developmental factors. This randomized controlled trial evaluated the Functional Recovery (FR) of pediatric patients undergoing ACL Reconstruction (ACLR), comparing Transphyseal Reconstruction (TPR) and physeal-sparing reconstruction (PSR). Forty-three young athletes (mean age 14.1 ± 2.3 years), including 29 boys and 14 girls, were randomized to TPR (n=23) or PSR (n=20). FR was assessed by using the Pediatric International Knee Documentation Committee (Pedi-IKDC) questionnaire at baseline, 8 months, and 12 months post-surgery. At the 12-month follow-up, the TPR group demonstrated a significantly greater improvement in Pedi-IKDC scores, with a 66.95% increase compared to 56.73% in the PSR group, reflecting notable differences in knee function between the groups at both 8 and 12 months (p < 0.001). Additionally, 80% of participants in the TPR group returned to sports, with 56% resuming limited activities, while the PSR group exhibited a slower recovery trajectory. These preliminary findings indicate that TPR provides superior FR and a faster return to sports compared to PSR, underscoring the importance of tailored rehabilitation protocols and long-term follow-up to optimize outcomes in SIP.

This systematic review and meta-analysis aimed to evaluate the efficacy of Low-Level Laser Therapy (LLLT) in the treatment of Rheumatoid Arthritis (RA), focusing on its effects on pain relief, grip strength, and morning stiffness. A comprehensive search was conducted across PubMed, Scopus, and Web of Science, yielding 3,111 articles. After eliminating duplicates and screening titles and abstracts, 94 full-text articles were assessed, and 23 studies met the eligibility criteria for inclusion in the systematic review. Of these, 22 studies were included in the meta-analysis. Data were extracted and analyzed using a random-effects model, with pooled Mean Differences (MD) calculated for the primary outcomes. The meta-analysis revealed that LLLT did not significantly reduce pain compared to placebo (MD = 0.00, 95% CI [-0.09, 0.09], p = 0.97). However, LLLT significantly improved grip strength (MD = -12.38, 95% CI [-17.42, -7.34], p < 0.01) and reduced morning stiffness (MD = -0.84, 95% CI [-1.33, -0.36], p < 0.01), despite substantial heterogeneity in these outcomes. LLLT shows promise in improving grip strength and reducing morning stiffness in RA patients, though it does not significantly impact pain relief. These findings highlight the potential role of LLLT as an adjunctive treatment for RA, with further research needed to optimize treatment protocols and clarify underlying mechanisms.

Surface Functional Electrical Stimulation (FES) is a well-studied intervention for multiple muscular disorders. However, it is still controversially discussed as a complementary therapy for complete facial paralysis. The aim of this intervention is to test a daily home-based ES concept as a pilot study regarding safety, feasibility, and effects on facial functionality and symmetry. In a prospective single-centre pilot study, 10 patients (median 61 years, denervation 130 d) with complete peripheral facial paralysis performed home-based FES of the affected lateral mouth region Stimulation parameters, facial paralysis scores and standardised photographs were assessed in monthly follow-ups. No serious adverse events appeared. Stimulation parameters could be constantly increased indicating effective muscle training while subjectively perceived functionality of the face improved. Thus, smile angle of the paralysed side improved as well. FES is a safe therapy model for application in facial nerve paralysis patients. A feasible stimulation protocol could be applied, which improved the functionality and symmetry of the stimulated facial region. A future controlled, randomised and double-blind follow-up study is needed to investigate these initial results in a further evolved replicable setting.

Functional Electrical Stimulation (FES) is an established intervention for a range of muscular and neurological disorders that has already been studied in numerous publications. However, its application to Peripheral Facial nerve Paralysis (PFP) still needs to be sufficiently investigated. As the first approach known to the authors, this study examines the effect of FES on the facial muscles in complete PFP using ultrasonography as a means of observation. In a prospective single-center observational pilot study, ten patients with complete PFP, confirmed by needle-electromyography (EMG), performed FES of the affected lateral mouth region at home twice daily for 20 minutes. The facial muscles' Cross-Sectional Area (CSA) was regularly assessed using sonographic quantification. While the CSA of most non-stimulated muscles decreased considerably during ongoing paralysis, a significant CSA increase of the Zygomaticus Muscle (ZYG), which was regularly subjected to FES, could be demonstrated. FES can halt the atrophy of denervated ZYG and potentially other facial muscles. Further investigations with a more significant patient collective are recommended. From now on, FES could be established as an additive method in the non-invasive treatment of PFP.

Obsessive-Compulsive Disorder (OCD) and Major Depressive Disorder (MDD) are prevalent psychiatric conditions, each affecting a substantial portion of the global population. When these conditions coexist with a Substance Use Disorder (SUD), the complexity of the clinical presentation is heightened. Herein, we describe two cases of individuals who have comorbid OCD and/or MDD and substance use disorder that highlight the importance of addressing the coexisting psychiatric illness when treating the SUD. These cases highlight the importance of tailored, multidisciplinary care, offering a potential therapeutic strategy based on medications for comprehensive recovery in individuals facing complex comorbid disorders. An integrated treatment approach, encompassing both psychiatric and substance treatment perspectives, is imperative.

Kearns-Sayre Syndrome (KSS) is a variant of mitochondrial disorder caused by a Mitochondrial Deoxyribonucleic Acid (mtDNA) deletion. Clinical manifestations of KSS can include different organ and system involvement. Different organ malfunctions, more often cardiac dysfunction, can lead to death. No effective treatment of this condition exists to date. Here, we report two patients with KSS. Female patient with a large-scale deletion of 7,020 base pairs (bp) suffered from hypogonadism, diabetes mellitus with fluctuating glucose levels, and had poor general health. A male patient with a common 4,977 bp deletion did not have diabetes mellitus but had impaired glucose tolerance. He also had a higher level of general health than our female patient. Both patients had reduced Bone Mineral Density (BMD). In female patients, calcium and vitamin D supplementation combined with metabolic therapy and nutritional drink supplements helped increase BMD (up to 32% in L1-L4). Comparing these two patients suggests that the larger the mtDNA deletion is, the more severe the course of the disease is. Not only does the size of the mtDNA deletion probably determine the severity of the disease, but also such factors as mtDNA heteroplasmy level, presence of mtDNA duplications, and pleioplasmy. Moreover, continuous nonconsecutive metabolic therapy and nutritional supplements are helpful in the prevention of deterioration of symptoms and general health.

Among the numerous changes that occur in skeletal muscle during aging, the reduced regeneration potential after an injury is largely due to the impaired ability of satellite cells to proliferate and differentiate. Herein, using the freeze-fracture electron microscopy technique, we analyzed both the incidence and size of dihydropyridine receptors (DHPRs) tetrads (4 particles) in cultured myotubes from a young subject (28 years) after 9 days of differentiation and from an old subject (71 years) after 9 and 12 days of differentiation. Compared to young myotubes, at 9 days of differentiation old myotubes exhibited: i) a lower incidence and a smaller size of DHPR clusters and ii) a lower number of complete tetrads. At 12 days of differentiation values of incidence, size and number of complete tetrads in old myotubes were instead comparable with those of young myotubes at 9 days of differentiation. Collectively, these results indicate that in aged myotubes the synthesis process of the proteins involved in the excitation-contraction coupling mechanism, such as the DHPR, is somehow slowed, supporting previous studies evidence of a decrease in the differentiation potential of myotubes from elderly individuals.

This study aims to evaluate the efficacy of selective laser trabeculoplasty in improving the intraocular pressure in patients diagnosed with open-angle glaucoma. A comprehensive search was performed across electronic databases, including PubMed, Scopus, and Web of Science, until June 2024, using keywords related to "selective laser trabeculoplasty" and "open-angle glaucoma." Studies were chosen based on set eligibility criteria. Data extraction was carried out by two independent reviewers, and statistical analyses were performed using a random-effects model to calculate the pooled mean differences in IOP reduction and overall success rates. The initial search yielded 3111 articles, with 23 studies included in the systematic review and 22 in the meta-analysis. The pooled MD in IOP reduction between the SLT and control groups was -1.44 mm Hg (95% CI: -2.19 to -0.70, p < 0.01). Subgroup analyses revealed a MD of -0.76 mm Hg (95% CI: -1.31 to -0.21, p < 0.01) when comparing SLT to medication, and -0.42 mm Hg (95% CI: -0.64 to -0.19, p < 0.01) when comparing 180-degree SLT to 360-degree SLT. The pooled success rate favored SLT with an odds ratio (OR) of 0.71 (95% CI: 0.51 to 0.99, p = 0.05). There was significant heterogeneity among the studies (I² = 71%). SLT is effective in lowering IOP in OAG patients, demonstrating significant efficacy compared to medication and different SLT protocols. The findings underscore SLT's potential as a reliable treatment option. However, the observed heterogeneity underscores the necessity for standardized protocols in future research to improve comparability and verify SLT's long-term effectiveness.

Acute muscle pain is muscle soreness that occurs during or within 24 hours of strenuous activity. Possible causes of acute muscle pain include localized muscle trauma, muscle tear, contusion with acute hemorrhage, or acute compartment syndrome. Isolated ruptures of the rectus femoris muscle are rare clinical conditions that result from excessive muscle strain following an abrupt contraction, incorrect movement, or sudden snap that exceeds the physiological limit of strain that the muscle can withstand. To date, there are few published reports evaluating the results of non-invasive treatment of such injuries. Herein, we report an unusual case of isolated distal rectus femoris tear in a 46-year-old female patient with no risk factors, who initially presented with extensor muscle weakness and pain and was treated conservatively with functional rest, physiotherapy, and cryotherapy.
