Background: The aim of the study was to assess gait pattern of patients diagnosed with fibromyalgia (FM) while performing demanding motor and/or cognitive dual tasks while walking. Further, idea was to explore possible correlations of dual task gait pattern alterations to patients’ functional status and presence or absence of clinical symptoms associated with FM. Methods: Twenty-four female FM patients and 24 healthy female subjects performed a basic walking task, a dual motor, a dual mental (cognitive) and a combined, dual motor and cognitive task simultaneously. Quantitative spatial (stride length) and temporal (cycle time, swing time and double support time) gait parameters were measured using GAITRite walkway system and their variability was assessed. Patients underwent clinical examination including assessment of functional status, pain and fatigue level, psychiatric and cognitive manifestations. Results: The motor, cognitive and combined dual tasks affect gait performance in FM patients. Difference in tasks between FM and healthy subjects was found as double support time prolongation. Comparison of tasks showing that cycle time in FM was longer than controls and stride length was shorter in patients for all conditions, while no changes were found in any of the gait parameters variability. Further, mental/cognitive dual tasks had a larger effect than motor tasks. Correlations were also found between depression and functional status of the patients and the gait parameters. Conclusions: Gait is affected in FM patients while dual task walking. No changes in stride-to-stride variability point that patients preserve stability in complex walking situations. Analysis of gait may provide additional information for the FM identification based on presence of clinical features and cognitive status. Correlation of dual task gait alterations with occurrence of clinical symptoms and influence of cognitive changes on gait pattern could additionally define FM subgroups.

Background: Diabetic neuropathy is one of the most common complications of diabetes mellitus. The aim of this study is to evaluate the Moveo device, a novel device that uses a machine learning (ML) algorithm to detect and track diabetic neuropathy. The Moveo device comprises 4 sensors positioned on the back of the hands and feet accompanied by a mobile application that gathers data and ML algorithms that are hosted on a cloud platform. The sensors measure movement signals, which are then transferred to the cloud through the mobile application. The cloud triggers a pipeline for feature extraction and subsequently feeds the ML model with these extracted features. Methods: The pilot study included 23 participants. Eleven patients with diabetes and suspected diabetic neuropathy were included in the experimental group. In the control group, 8 patients had suspected radiculopathy, and 4 participants were healthy. All participants underwent an electrodiagnostic examination (EDx) and a Moveo examination, which consists of sensors placed on the feet and back of the participant’s hands and use of the mobile application. The participant performs six tests that are part of a standard neurological examination, and a ML algorithm calculates the probability of diabetic neuropathy. A user experience questionnaire was used to compare participant experiences with regard to both methods. Results: The total accuracy of the algorithm is 82.1%, with 78% sensitivity and 87% specificity. A high linear correlation up to 0.722 was observed between Moveo and EDx features, which underpins the model’s adequacy. The user experience questionnaire revealed that the majority of patients preferred the less painful method. Conclusions: Moveo represents an accurate, easy-to-use device suitable for home environments, showing promising results and potential for future usage.

Objectives: This study aimed to investigate the efficacy of glucosamine-sulfate (GS), nonanimal chondroitin-sulfate (naCS), and S-adenosylmethionine (SAMe) combination on ultrasound findings, inflammation, pain, and functionality in knee osteoarthritis. Patients and methods: In the prospective, randomized, double-blind, placebo-controlled pilot study conducted between August 2019 and November 2019, 120 participants (28 males, 92 females; mean age: 66.4±7.9 years; range, 42.4 to 74.5 years) were randomized at a 1:1:1 ratio to the placebo group, the first experimental group (a combination of GS, naCS, and SAMe was administered to the experimental groups. The first experimental group received 375 mg of GS, 300 mg of naCS, and 100 mg of SAMe, whereas the second experimental group received 750 mg of GS, 600 mg of naCS, and 200 mg of SAMe). Laboratory (erythrocyte sedimentation rate, C-reactive protein, tumor necrosis factor alpha, interleukin [IL]-1β, IL-6, IL-17), clinical (Visual Analog Scale [VAS], short form health survey [SF-36], the Western Ontario and McMaster Universities Arthritis Index [WOMAC], and the Tegner Lysholm Knee Scoring Scale [TLKS]), and musculoskeletal ultrasound (MSUS) assessments were performed at baseline and after three and six months. Results: A minor increase was observed in the second experimental group after six months using ultrasonography to evaluate articular cartilage thickness (p

Fibromyalgia and osteoarthritis are among the most prevalent rheumatic conditions worldwide. Nonpharmacological interventions have gained scientific endorsements as the preferred initial treatments before resorting to pharmacological modalities. Repetitive transcranial magnetic stimulation (rTMS) is among the most widely researched neuromodulation techniques, though it has not yet been officially recommended for fibromyalgia. This review aims to summarize the current evidence supporting rTMS for treating various fibromyalgia symptoms. Recent findings: High-frequency rTMS directed at the primary motor cortex (M1) has the strongest support in the literature for reducing pain intensity, with new research examining its long-term effectiveness. Nonetheless, some individuals may not respond to M1-targeted rTMS, and symptoms beyond pain can be prominent. Ongoing research aims to improve the efficacy of rTMS by exploring new brain targets, using innovative stimulation parameters, incorporating neuronavigation, and better identifying patients likely to benefit from this treatment. Summary: Noninvasive brain stimulation with rTMS over M1 is a well-tolerated treatment that can improve chronic pain and overall quality of life in fibromyalgia patients. However, the data are highly heterogeneous, with a limited level of evidence, posing a significant challenge to the inclusion of rTMS in official treatment guidelines. Research is ongoing to enhance its effectiveness, with future perspectives exploring its impact by targeting additional areas of the brain such as the medial prefrontal cortex, anterior cingulate cortex, and inferior parietal lobe, as well as selecting the right patients who could benefit from this treatment.

Background: The European League Against Rheumatism (EULAR), in collaboration with the European Scleroderma Trial and Research group (EUSTAR), published the first set of treatment recommendations for systemic sclerosis (SSc) in 2009, with subsequent updates in 2016 and 2023. Objectives: This study aimed to evaluate how rheumatologists’ clinical approaches to the treatment of SSc evolved following the 2016 update of the clinical management guidelines. Methods: Medication use for SSc was analyzed in a cohort of 378 patients. The patients were stratified based on enrollment before (233 patients) and after (145 patients) the guideline update, and medication usage was compared between the two groups. Results: Although all patients presented with Raynaud’s phenomenon (RP), only 35% received calcium channel blockers. Medications such as iloprost, phosphodiesterase type 5 (PDE-5) inhibitors, fluoxetine, and bosentan, recommended for the treatment of RP and digital ulcers, were not approved for SSc by the Republic Health Insurance Fund. Treatment for pulmonary arterial hypertension (PAH) was administered to only 16 patients (4.2%), including 2 who received bosentan, 10 who received PDE-5 inhibitors, and 4 who were treated with riociguat. The use of PDE-5 inhibitors increased following the 2016 update of the guidelines. Cyclophosphamide was consistently prescribed for interstitial lung disease (ILD), with an increased frequency observed after the guideline update. No significant differences were observed in the use of methotrexate for skin involvement, ACE inhibitors for scleroderma renal crisis, or antibiotics for gastrointestinal symptoms. Proton pump inhibitors (PPIs) were prescribed to 87.3% of patients with gastrointestinal involvement, with an increase in use of both PPIs and prokinetic agents following the guideline update. Conclusions: Rheumatologists’ adherence to the EULAR/EUSTAR guidelines varied considerably, with 25% to 100% of eligible patients receiving the recommended treatments. Concordance improved in the management of PAH, ILD, and gastrointestinal involvement after the 2016 guideline update.

Introduction/Objective. The aim of our study was to retrospectively analyze data about efficacy and persistence on different anti-TNF? treatment in spondyloarthritis (SpA). Methods. We retrospectively analyzed SpA patients whose data were entered into the Serbian national SpA registry. All patients were divided in two groups: non-switcher (patients who were treated with one anti-TNF?) and switcher group (who has switched from first to second and third anti-TNF?). Disease activity was measured by the Ankylosing Spondylitis Disease Score and the Bath Ankylosing Spondylitis Disease Activity Index and functional status was measured by the Bath Ankylosing Spondylitis Functional Index. Results. We identified 290 SpA patients ? 250 patients with axial SpA (axSpA) and 40 patients with peripheral SpA (pSpA). Among 250 patients with axSpA, 192 (76.8%) did not change first anti-TNF?, while 58 (23.2%) switched to the second and 14 (5.6%) switched to the third anti-TNF?. Among 40 patients with pSpA, 29 (72.5%) did not change first anti-TNF? while 11 (27.5%) switched to the second and three (7.5%) switched to the third anti-TNF?. Survival on the first anti-TNF? was 35.16 ? 28.5 months (switchers 29.41 ? 21.89 vs. non-switchers 36.89 ? 30.04). ?t the moment of this cross-section 37 (19.3%) patients still had very high disease activity, while only 75 (39%) patients had inactive disease. Conclusions. In real-life clinical practice in our country, as well as in others, there is reluctance to anti- TNF? switch in SpA patients. Administrative limitations and national reimbursement policy could be one of the main reasons limiting treat to target implementation in SpA patients. Additionally, specific drug efficacy on extra-articular manifestations is often the reason for choosing the first line medication or switching to the next one.
