Repetitive Transcranial Magnetic Stimulation in Fibromyalgia: Exploring the Necessity of Neuronavigation for Targeting New Brain Regions.

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.

Wearable Movement Exploration Device with Machine Learning Algorithm for Screening and Tracking Diabetic Neuropathy-A Cross-Sectional, Diagnostic, Comparative Study.

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.

The short-term effect of glucosamine-sulfate, nonanimal chondroitin-sulfate, and S-adenosylmethionine combination on ultrasonography findings, inflammation, pain, and functionality in patients with knee osteoarthritis: A pilot, double-blind, randomized, placebo-controlled clinical trial.

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]-1ß, 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<0.05). The investigational product's superiority in reducing osteoarthritis ultrasonographic findings was not proven. A moderately negative association was found between cartilage thickness and VAS scores at baseline (ρ=-0.36, p<0.01), while the presence of massive osteophytes on MSUS showed a low to moderate association with all clinical outcomes. There was no difference in the delta changes between groups for the VAS, TLKS, WOMAC, and SF-36. The only serum inflammatory marker outside the reference range was IL-1ß, but no significant changes were observed after six months. Conclusion: According to the results of our investigation, treatment for knee osteoarthritis should be evaluated using more objective outcomes. The most important conclusion of our study is that IP may result in a slight increase in articular cartilage thickness, which was associated with a decrease in pain intensity at baseline. Clarification of the potential influence of this combination on radiographic progression and laboratory markers of inflammation requires further exploration.

Assessment of gait in patients with fibromyalgia during motor and cognitive dual task walking: a cross-sectional study.

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.

Problems in surveillance on safe immunization conducting in everyday practice.

PURPOSE: Vaccination is the fastest, most efficient and the cheapest measure to prevent communicable diseases. The purpose of the work was to evaluate the results of primary vaccination as well as the first revaccination by DPT,OPV and MMR vaccines. WORK METHOD: Descriptive epidemiological study was used. The investigation was done in the Primary Health Center in Nis and it involved all the children who were born in 2000, 2001, 2006 and 2007. WORK RESULTS: A total number of 1863 vaccination records were examened. In the sample of examened records of children who were born in 2000 and 2001, there were 155 children (12.05%) who were vaccinated with different vaccines and according to the different vaccination schedules. The number of childern born in 2006 and 2007 was slightly higher and it was (14.70%). In the first group (children who were born in 2000 and 2001) there were 43 children (4.51%) who were not vaccinated (3 children haven't been vaccinated by DPT, and other 40 haven't been vaccinated by MMR). Similar situation was in the second group (children who were born in 2006 and 2007) in which 37 children (4.03%) haven't been vaccinated at all (3 of them by DPT and other 34 by MMR). In both observed groups DPT vaccine immunization started out late. 48.25% of children from the first group haven't been vaccinated with the first dose of DPT on time. 58.53% of children born in 2006 and 2007 haven't been vaccinated with the first dose of DPT on time. The first re-vaccination by DPT was also late in children born 2000 and 2001 (16.6% vs 45.36%). It was also delayed the first revaccination by MMR (10.3% vs 22.53%). DISCUSSION: To achieve the expected effects should be vaccinated at least 95% of planned persons but also make timely vaccinations. While the main goal of immunization is to prevent illness and death, the overriding concern of any public health intervention must be "Primum non nocere". CONCLUSION: A small number of post-vaccinal reactions is registered, and there haven't been registered cases of adverse events following immunization or serious reactions that would be contraindications for further immunization.

[Association of stressful life events with acute myocardial infarction in population in the city of Nis within the period from 1998-2000].

BACKGROUND/AIM: Stressful life events present a very important category of psychosocial stress. A few studies have showed that a psychosocial stress represents a very important risk factor for acute myocardial infarction (AMI), but measures of stress may not be suitable for different countries, cultures and ethnic groups. The aim of this study was to investigate the relation of stressful life events with AMI in the period of 1998-2000 in the population of the city of Nis. METHODS: A case-control study included 100 patients with the first MI (in the period 1998-2000) and 100 healthy subjects, matched with respect to sex and age (+/- 2 years) from the city of Nis. The data of stressful life events were obtained by the Scaling of life events by Paykel ES, modified by the authors consistent with the examined population and the period of investigation. The Yates chi2 test, odds ratio - OR and their 99% interval of confidence were used as statistical procedures. RESULTS: The results showed that stressful life events in the period of investigation were very important risk factors for AMI with a statistically significant level (p = 0.000). Huge financial problems (OR = 202.36, Ci = 24.82-4387.58), violation of law (OR = 168.00, Ci = 10.66-6658.96) and serious illness of family members (OR = 159.60, Ci = 19.05- 3514.81) were the highest risk for AMI. The patients who reported that his/her son or other member of family had been gone to the army (or mobilization) before the illness onset, had 138 times higher risk of AMI (Ci = 14.98-3222.47, chi2 = 40.95, p = 0.000), while the patients who had mobilized themselves had 84 times higher risk (Ci = 7.00-2363.06, chi2= 23.87, p = 0.000). Effect of several stressful life events lead to significantly increased risk of AMI andthat significance is larger as the number of life events is more frequent (one life event: OR = 28.41, Ci = 3.73-593.52; chi2 = 17.40, p = 0.000; ? 4: OR = 336.00, Ci = 28.31-9760.28, chi2 = 50,43, p = 0,000). CONCLUSION: These findings indicate that stressful life events are associated with AMI and that they are very important for further epidemiological investigation of the triggering mechanisms and should improve preventive strategies of this serious disorder.

[An epidemic of tularemia in the Nish area]. / Epidemija tularemije u Niskom okrugu.

Tularaemia, as a rare disease, surprised medical workers in 1999 and 2000 when it was detected and diagnosed in 31 patients. In 1999 patients were registered in villages of the Sokobanja community, and in 2000 also in other communities in the district of Nish. Patients were peasants, mostly housewives. Glandular form of the disease was dominant. The main clinical symptoms were: tonsillitis, pain in the region of enlarged lymphatic glands and temperature, Biohumoral syndrome presented accelerated sedimentation of erythrocytes and elevated fibrinogen values. Antibody titer of Francisella tularensis was extremely high in the majority of patients. The disease was cured in all patients: in 27 patients after the first therapy, in 4 subjects after recidivation and 5 patients were surgically treated.
