Lactylation: A Novel Post-Translational Modification with Clinical Implications in CNS Diseases.

Lactate, an important metabolic product, provides energy to neural cells during energy depletion or high demand and acts as a signaling molecule in the central nervous system. Recent studies revealed that lactate-mediated protein lactylation regulates gene transcription and influences cell fate, metabolic processes, inflammation, and immune responses. This review comprehensively examines the regulatory roles and mechanisms of lactylation in neurodevelopment, neuropsychiatric disorders, brain tumors, and cerebrovascular diseases. This analysis indicates that lactylation has multifaceted effects on central nervous system function and pathology, particularly in hypoxia-induced brain damage. Highlighting its potential as a novel therapeutic target, lactylation may play a significant role in treating neurological diseases. By summarizing current findings, this review aims to provide insights and guide future research and clinical strategies for central nervous system disorders.

Cardiovascular autonomic neuropathy and the risk of diabetic kidney disease.

Background: Cardiovascular autonomic neuropathy (CAN) is known to affect patients with diabetes mellitus (DM) and cause adverse renal outcomes. We aimed to analyze the association between CAN and diabetic kidney disease (DKD). Method: We enrolled 254 DM patients (mean age, 56.7 ± 15.2 years; male: female ratio, 1.17:1) with 19 (7.5%) type 1 DM patients and 235 (92.5%) type 2 DM patients. All patients had undergone cardiovascular autonomic function tests between January 2019 and December 2021 in a tertiary hospital in Korea. Cardiovascular autonomic neuropathy was categorized as normal, early, or definite after measuring three heart rate variability parameters. Diabetic kidney disease refers to a persistently elevated urinary albumin-creatinine ratio (uACR ≥30 mg/g) or reduced estimated glomerular filtration rate (eGFR <60 mL/min/1.73 m2). Logistic and Cox regression analyses were performed. Results: Patients with elevated uACR (n=107) and reduced eGFR (n=32) had a higher rate of definite CAN. After adjusting for covariates, definite CAN was associated with elevated uACR (OR=2.4, 95% CI 1.07-5.36) but not with reduced eGFR (OR=3.43, 95% CI 0.62-18.90). A total of 94 patients repeated uACR measurements within 2 years (mean follow-up, 586.3 ± 116.8 days). Both definite and early CAN were independent risk factors for elevated uACR (HR=8.61 and 8.35, respectively; both p<0.05). In addition, high-density lipoprotein cholesterol, ACE inhibitors/angiotensin receptor blockers and glucagon-like peptide-1 receptor agonists were independent protective factors for elevated uACR (HR=0.96, 0.25, and 0.07, respectively; all p<0.05). Conclusion: Cardiovascular autonomic neuropathy is a potential indicator of DKD. Comprehensive management of DKD in the early stages of CAN may prevent microalbuminuria.

EXPRESS: Human microglia polarization following infection with the Lyme disease spirochete.

Infection with Borrelia burgdorferi (Bb) can spread and cause CNS involvement, known as neuroborreliosis. Microglia phagocytose bacteria, mediate inflammation, and elicit an immune response towards the spirochete. Like other tissue macrophages, microglia can polarize into two different modulatory phenotypes, M1 and M2.We explored human microglial polarization changes upon infection with Bb.HMC3 human microglia cell line was infected with Bb for 24 hours. Expression of polarization markers was evaluated via flow cytometry at 4 and 24 hours. Secreted immunological mediators were evaluated using a multiplex ELISA system at 4,18, and 24 hours.An early decrease followed by a later increase in expression of M1 polarization marker iNOS was observed at 4 hours, and 24 hours, respectively. A decrease in M2 marker CX3CR1 occurred at 24 hours. There were no changes in expression of M1 markers CD14, or in M2 markers CD163 and CD206. Multiplex ELISA evidenced an increase in secretion of activation markers MIP-1α, MIP- 1ß, IP-10, chemotactic factor MCP-1, M1 polarization cytokine IL-8, and VEGF, at 4, 18, and 24 hours.A decrease of iNOS at 4 hours of infection suggests a diminished production of reactive nitrogen species that are a critical component of innate defense against infection. Increased iNOS and simultaneously decreased expression of CX3CR1 at 24 hours, may suggest initiation of neuroprotective regulation of microglia recruitment to neuroinflammation. The dynamics of major inflammatory cytokines appear to be important in the microglial response to Bb should be further studied as these could become therapeutic targets in neuroborreliosis.

[Research progress in osthole for prevention and treatment of central nervous system diseases].

Central nervous system(CNS) disorders can significantly impact patients' daily lives, impairing their ability to work and imposing a substantial financial burden on their families. In recent years, the incidence of CNS diseases has shown a significant increase with the continuous improvement of the quality of life and the aging problem. Therefore, the search for new preventive and curative drugs has been a research hotspot for this group of diseases. Osthole(OST), isolated from Umbelliferae such as Cnidium monnieri, Angelica sinensis, and Heracleum hemsleyanum, possesses a variety of pharmacological effects such as neuroprotective, antioxidant, anti-inflammatory, and antithrombotic effects. There is increasing evidence that OST has demonstrated significant preventive and curative effects in various CNS disease models. This paper systematically reviewed the research progress of OST in preventing and treating CNS diseases by reviewing domestic and international literature to provide more in-depth theoretical support for the future clinical application of OST in the prevention and treatment of CNS diseases.

The psychometric properties of the Quality of Life in Neurological Disorders (Neuro-QoL) measurement system in neurorehabilitation populations: a systematic review.

OBJECTIVE: To systematically review the literature of existing evidence on the measurement properties of the Quality of Life in Neurological Disorders (Neuro-QoL) measurement system among neurorehabilitation populations. DATA SOURCES: The Consensus-based Standards for the selection of health Measurement Instruments (COSMIN) guided this systematic review in which we searched nine electronic databases and registries, and hand-searched reference lists of included articles. STUDY SELECTION: Two independent reviewers screened selected articles and extracted data from 28 included studies. DATA EXTRACTION: COSMIN's approach guided extraction and synthesizing measurement properties evidence (insufficient, sufficient), and the modified GRADE approach guided synthesizing evidence quality (very-low, low, moderate, high) by diagnosis. DATA SYNTHESIS: Neuro-QoL has sufficient measurement properties when used by individuals with Huntington's disease, Multiple Sclerosis, Parkinson's disease, stroke, lupus, cognitive decline, and amyotrophic lateral sclerosis. The strongest evidence is for the first four conditions, where test-retest reliability, construct validity, and responsiveness are nearly always sufficient (GRADE: moderate-high). Structural validity is assessed only in multiple sclerosis and stroke but is often insufficient (GRADE: moderate-high). Criterion validity is sufficient in some stroke and Huntington's disease domains (GRADE: high). Item response theory analyses were reported for some stroke domains only. There is limited, mixed evidence for responsiveness and measurement error (GRADE: moderate-high), and no cross-cultural validity evidence CONCLUSIONS: Neuro-QoL domains can describe and evaluate patients with Huntington's disease, multiple sclerosis, Parkinson's disease, and stroke, but predictive validity evidence would be beneficial. In the other conditions captured in this review, a limited number of Neuro-QoL domains have evidence for descriptive use only. For these conditions, further evidence of structural validity, measurement error, cross-cultural validity and predictive validity would enhance the use and interpretation of Neuro-QoL.

How to optimise medicines management for people with Parkinson's disease in hospital.

RATIONALE AND KEY POINTS: Hospital admissions can be challenging for people with Parkinson's disease, in part because of the lack of understanding, among some healthcare professionals, of the importance of administering antiparkinsonian medicines on time. This article outlines the steps that nurses can take to optimise medicines management for people with Parkinson's disease who are admitted to hospital. • Pharmacotherapy is the primary treatment for Parkinson's disease and aims to increase dopamine levels in the brain to relieve symptoms. • People with Parkinson's disease require careful administration, titration, adjustment and monitoring of their antiparkinsonian medicines regimen, which is highly individualised. • It is crucial that people with Parkinson's disease take their antiparkinsonian medicines at exactly the right time, since the inaccurate timing of these medicines can have significant adverse health implications. REFLECTIVE ACTIVITY: 'How to' articles can help to update your practice and ensure it remains evidence-based. Apply this article to your practice. Reflect on and write a short account of: • How this article might improve your practice when undertaking medicines management for people with Parkinson's disease in hospital. • How you could use this information to educate nursing students or your colleagues on optimising medicines management for people with Parkinson's disease in hospital.

Prerequisites and barriers to telerehabilitation in patients with neurological conditions: A narrative review.

BACKGROUND: A field of study that uses telerehabilitation (TR) is neurorehabilitation; however, standards for medical and technological applications, medicolegal and ethical regulations, and other aspects of neuro-TR are still being developed. OBJECTIVE: To address the prerequisites and barriers for implementing TR in neurorehabilitation in the light of present findings. METHODS: A narrative review was conducted based on specific questions about the prerequisites for neuro-TR and barriers to its implication. According to a foreground search strategy in the context of neurorehabilitation using TR in neurological patient population, PubMed, EMBASE and Cochrane databases were searched and reviewed. RESULTS: Barriers and prerequisites for neuro-TR were mostly grouped under the categories of administrative/organizational, human (beneficiaries/providers), technical, and ethical. Apart from the technical framework, knowledge and the presence of an administrative leader responsible for overseeing TR are crucial prerequisites. The internet and technological constraints rank highest among the barriers. CONCLUSION: Since neuro-TR is relatively new with minimal guidelines and regulations, highly technologic, and lack of established practices, it is imperative to determine and fully comprehend the criteria for its uses. After the prerequisites are established, it is imperative to recognize and address implementation constraints, which may differ depending on the community's infrastructure and neurologic condition.

Group based trajectory modeling identifies distinct patterns of sympathetic hyperactivity following traumatic brain injury.

Background: Paroxysmal Sympathetic Hyperactivity (PSH) occurs with high prevalence among critically ill Traumatic Brain Injury (TBI) patients and is associated with worse outcomes. The PSH-Assessment Measure (PSH-AM) consists of a Clinical Features Scale (CFS) and a Diagnosis Likelihood Tool (DLT), intended to quantify the severity of sympathetically-mediated symptoms and likelihood that they are due to PSH, respectively, on a daily basis. Here, we aim to identify and explore the value of dynamic trends in the evolution of sympathetic hyperactivity following acute TBI using elements of the PSH-AM. Methods: We performed an observational cohort study of 221 acute critically ill TBI patients for whom daily PSH-AM scores were calculated over the first 14 days of hospitalization. A principled group-based trajectory modeling approach using unsupervised K-means clustering was used to identify distinct patterns of CFS evolution within the cohort. We also evaluated the relationships between trajectory group membership and PSH diagnosis, as well as PSH DLT score, hospital discharge GCS, ICU and hospital length of stay, duration of mechanical ventilation, and mortality. Baseline clinical and demographic features predictive of trajectory group membership were analyzed using univariate screening and multivariate multinomial logistic regression. Results: We identified four distinct trajectory groups. Trajectory group membership was significantly associated with clinical outcomes including PSH diagnosis and DLT score, ICU length of stay, and duration of mechanical ventilation. Baseline features independently predictive of trajectory group membership included age and post-resuscitation motor GCS. Conclusions: This study adds to the sparse research characterizing the heterogeneous temporal trends of sympathetic nervous system activation during the acute phase following TBI. This may open avenues for early identification of at-risk patients to receive tailored interventions to limit secondary brain injury associated with autonomic dysfunction and thereby improve TBI patient outcomes.

Complete Third Nerve Palsy: A Rare Occurrence in Fulminant IIH Case Report.

Idiopathic Intracranial Hypertension (IIH) is a condition characterized by elevated intracranial pressure of unknown cause. Classic symptoms include headache, vision loss, transient visual obscurations (TVOs), diplopia (often from sixth nerve palsy), divergence insufficiency, and pulsatile tinnitus. However, atypical presentations can occur, including asymmetric or unilateral papilledema, oculomotor disturbances such as third and fourth nerve palsies, internuclear ophthalmoplegia, and olfactory dysfunction, among others. Fulminant IIH is a subtype of IIH defined as acute onset of rapid worsening of vision over days (less than 4 weeks between symptom onset and severe vision loss). This case report details a rare presentation of fulminant IIH with unilateral complete third nerve palsy.

Enhancing therapeutic potential: Human adipose-derived mesenchymal stem cells modified with recombinant adeno-associated virus expressing VEGF165 gene for peripheral nerve injury.

This study aimed to investigate the therapeutic potential of human adipose-derived mesenchymal stem cells (hADSCs) modified with recombinant adeno-associated virus (rAAV) carrying the vascular endothelial growth factor 165 (VEGF165) gene in peripheral nerve injury (PNI). The hADSCs were categorized into blank, control (transduced with rAAV control vector), and VEGF165 (transduced with rAAV VEGF165 vector) groups. Subsequently, Schwann cell differentiation was induced, and Schwann cell markers were assessed. The sciatic nerve injury mouse model received injections of phosphate-buffered saline (PBS group), PBS containing hADSCs (hADSCs group), rAAV control vector (control-hADSCs group), or rAAV VEGF165 vector (VEGF165-hADSCs group) into the nerve defect site. Motor function recovery, evaluated through the sciatic function index (SFI), and nerve regeneration, assessed via toluidine blue staining along with scrutiny of Schwann cell markers and neurotrophic factors, were conducted. Modified hADSCs exhibited enhanced Schwann cell differentiation and elevated expression of Schwann cell markers [S100 calcium-binding protein B (S100B), NGF receptor (NGFR), and glial fibrillary acidic protein (GFAP)]. Mice in the VEGF165-hADSCs group demonstrated improved motor function recovery compared to those in the other three groups, accompanied by increased fiber diameter, axon diameter, and myelin thickness, as well as elevated expression of Schwann cell markers (S100B, NGFR, and GFAP) and neurotrophic factors [mature brain-derived neurotrophic factor (BDNF) and glial cell-derived neurotrophic factor (GDNF)] in the distal nerve segment. rAAV-VEGF165 modification enhances hADSC potential in PNI, promoting motor recovery and nerve regeneration. Elevated Schwann cell markers and neurotrophic factors underscore therapy benefits, providing insights for nerve injury strategies.

Cellular senescence: A novel therapeutic target for central nervous system diseases.

The underlying mechanisms of diseases affecting the central nervous system (CNS) remain unclear, limiting the development of effective therapeutic strategies. Remarkably, cellular senescence, a biological phenomenon observed in cultured fibroblasts in vitro, is a crucial intrinsic mechanism that influences homeostasis of the brain microenvironment and contributes to the onset and progression of CNS diseases. Cellular senescence has been observed in disease models established in vitro and in vivo and in bodily fluids or tissue components from patients with CNS diseases. These findings highlight cellular senescence as a promising target for preventing and treating CNS diseases. Consequently, emerging novel therapies targeting senescent cells have exhibited promising therapeutic effects in preclinical and clinical studies on aging-related diseases. These innovative therapies can potentially delay brain cell loss and functional changes, improve the prognosis of CNS diseases, and provide alternative treatments for patients. In this study, we examined the relevant advancements in this field, particularly focusing on the targeting of senescent cells in the brain for the treatment of chronic neurodegenerative diseases (e.g., Alzheimer's disease, Parkinson's disease, and multiple sclerosis) and acute neurotraumatic insults (e.g., ischemic stroke, spinal cord injury, and traumatic brain injury).

A novel concern from two sample Mendelian randomization study: The effects of air pollution exposure on the cardiovascular, respiratory, and nervous system.

BACKGROUND: Cardiovascular, respiratory, and nervous system diseases have high morbidity and mortality rates, but the causal relationship between air pollution and these diseases remains controversial. METHODS: We conducted a large-scale genome-wide association (GWAS) study using Mendelian randomization (MR) to investigate the association between air pollution like Nitrogen dioxide (NO2), Nitrogen oxides (NOX), Particulate matter with diameter<2.5µm (PM2.5), Particulate matter with diameter<10µm (PM10) and cardiovascular, respiratory, and nervous system diseases, including acute myocardial infarction, heart failure, asthma, chronic obstructive pulmonary disease (COPD), pneumonia, stroke and Parkinson's disease. This study included 337,199 patients with acute myocardial infarction, 178,726 patients with heart failure, 463,010 patients with asthma, 462,933 patients with COPD, 486,484 patients with pneumonia, 484,598 patients with stroke, and 482,730 patients with Parkinson's disease. All genetic tools were identified from GWAS. The association effects of environmental pollution and these diseases were investigated using MR analysis, sensitivity analysis with heterogeneity, pleiotropy test, and leave-one-out test. RESULTS: Our MR analysis showed the association between NOX and the development of COPD and stroke (Odds ratio (OR)=1.010, 95 % Confidence interval (CI): 1.000～1.020, P=0.046; OR=1.017, 95 %CI:1.003-1.031, P=0.019), the association between PM2.5 and the development of asthma, COPD and stroke (OR=1.013, 95 %CI:1.003-1.024, P=0.011; OR=1.010, 95 %CI:1.000-1.019, P=0.035; OR=1.019, 95 %CI:1.004-1.033, P=0.012). No significant associations were found between the rest of the air pollution exposures and diseases. Leave-one-out sensitivity analysis showed stable results. CONCLUSIONS: The study clarifies the relationship between air pollution and cardiovascular, respiratory, and nervous system diseases, providing valuable evidence for environmental pollution prevention and population health monitoring, and provides a clear direction and evidence for the subsequent investigation of the association between air pollution and diseases.

The role of chemotherapy in hematopoietic stem cell transplantation for autoimmune disorders: From lymphoablative to myeloablative conditioning protocols.

Hematopoietic stem cell transplantation (HSCT) is a medical procedure used mainly for the treatment of onco-hematologic disorders. Over the last two decades, autologous HSCT has been explored for the treatment of neurologic autoimmune diseases (ADs), being multiple sclerosis (MS) the most frequent indication in this setting. HSCT is characterized by the sequential administration of a conditioning regimen (CR) and the infusion of hematopoietic stem cells (HSCs), previously collected either by the individual himself in the autologous transplant (AHSCT), or by a healthy donor in allogeneic HSCT. CR consists of the administration of high-dose chemotherapy and/or total body irradiation (TBI), that in ADs is usually associated with an immunodepleting serotherapy, either by an animal-derived polyclonal serum or a monoclonal antibody (MoAb), to induce intense immunosuppression. CRs are classified according to the European Society for Blood and Marrow Transplantation (EBMT) guidelines for HSCT in ADs in three grades of intensity according to the degrees of depletion of the hemato-lymphopoietic system induced. In the present chapter, after a brief overview of mobilization and CR adopted in the neurologic autoimmune setting, the role of chemotherapy in HSCT will be discussed, providing a historical perspective on the use of different regimens and summarizing the available evidence on potential associations between CR and outcomes.

End-tidal carbon dioxide and arterial to end-tidal carbon dioxide gradient are associated with mortality in patients with neurological injuries.

Pre-hospital end-tidal carbon dioxide (EtCO2) monitoring and arterial to end-tidal carbon dioxide gradient (Pa-EtCO2) have been associated with mortality in patients with traumatic brain injury. Our study aimed to analyze the association between alveolar EtCO2 or Pa-EtCO2 and mortality in patients admitted in intensive care unit (ICU) with neurological injuries. In our retrospective analysis from using large de-identified ICU databases (MIMIC-III and -IV and eICU databases), we included 2872 ICU patients with neurological injuries, identified according to the International Classification of Diseases (ICD-9 and -10), who underwent EtCO2 monitoring. We performed logistic regression and extended Cox regression to assess the association between mortality and candidate covariates, including EtCO2 and Pa-EtCO2. In-hospital mortality was 26% (n = 747). In univariate analysis, both the Pa-EtCO2 gradient and EtCO2 levels during the first 24 h were significantly associated with mortality (for a 1 mmHg increase: OR = 1.03 [CI95 1.016-1.035] and OR = 0.94 [CI95 0.923-0.953]; p < 0.001). The association remained significant in multivariate analysis. The time-varying evolution of EtCO2 was independently associated with mortality (for a 1 mmHg increase: HR = 0.976 [CI95 0.966-0.985]; p < 0.001). The time-varying Pa-EtCO2 gradient was associated with mortality only in univariate analysis. In neurocritical patients, lower EtCO2 levels at admission and throughout the ICU stay were independently associated with mortality and should be avoided.

Combined generalized and focal epilepsy with reflex features in Adaptor protein complex 4-associated hereditary spastic paraplegias: A cohort observational study.

BACKGROUND: Patients with genetic deficiency of the adaptor protein complex 4 (AP-4) exhibit earlyonset developmental delay, spastic diplegia, intellectual disability, speech impairment. The phenotype overlaps with other hereditary spastic paraplegias and cerebral palsies. Febrile seizures are common at onset. Epilepsy has been described in more than half of cases, arising in early infancy often with status epilepticus, but no typical seizure semiology or electroencephalographic features have been identified thus far. PURPOSE: We aimed to specifically investigate the epileptological characteristics of the syndrome to unveil possible biomarkers of seizure development and prognosis in AP-4 deficiency. METHODS: Observational cohort study on patients with bi-allelic pathogenic variants in AP-4 subunits and epilepsy. We focused on the seizure semiology, electroencephalographic characteristics and response to antiseizure medications. RESULTS: Patients harboured pathogenic variants in AP4S1 (n = 5) or AP4M1 (n = 1). The phenotype included spastic paraparesis, intellectual disability, speech/language impairment, microcephaly, and MRI evidence of hypoplasia of the corpus callosum. In 66 % of the patients, febrile seizures preceded the onset of epilepsy, which spanned from infancy to adolescence (range=14 months-13 years). Absences (66 %) and focal motor seizures (50 %) were common. No patient met the criteria for drug-resistance. Peculiar electroencephalographic features arose after the epilepsy onset and persisted at long-term follow-up: bilateral and asynchronous focal discharges combined with independent diffuse spike-wave-discharges (100 %) and reflex abnormalities (66 %). CONCLUSION: In AP-4 complex disease, epilepsy could arise beyond early infancy, until adolescence, with variable combination of generalized and focal seizures. The prognosis was favourable. We observed a common electroencephalographic signature - combined focal/generalized and reflex abnormalities - which may constitute a biomarker of AP-4 deficiency with epilepsy, applicable to inform genetic testing and disentangle the differential diagnosis.

Hand cold stress testing among Arctic open-pit miners: a clinical study.

Objectives. This study aimed to evaluate the influence of individual characteristics (sex, age, body mass index [BMI] and smoking habits) on the tolerance time, pain ratings and rewarming time of hand cold stress testing (CST). Methods. We included 153 subjects (63% men) working in a Swedish open-pit mine (participation rate 41%). The right hand was immersed in 3 °C circulating water for up to 45 s. Pain ratings were registered every fifth second using a visual analog scale. Results. The tolerance time (mean ± standard deviation) was 35 ± 12 s for men and 29 ± 14 s for women (p = 0.007). The youngest age group (18-29 years) had the longest tolerance time, while the oldest group (54-65 years) had the shortest (p = 0.005). Women had significantly higher pain ratings than men after 5, 10 and 25 s. The group with the highest BMI had the shortest rewarming time (p < 0.001). Conclusions. Age and sex influenced the tolerance time of hand CST, while only sex affected the pain ratings and BMI the rewarming time. When performing CST in future studies, these parameters should be considered.

The Effects of Sport Participation for Adults With Physical or Intellectual Disability: A Scoping Review.

BACKGROUND: Adults with physical or intellectual disability are less active than those without disability. OBJECTIVE: To review literature regarding sport participation in adults with physical or intellectual disability. Specifically, to examine characteristics of available studies including participants, interventions, outcomes, and impact. METHODS: A scoping review was completed. Searches of 6 databases and a trial registry plus citation tracking were undertaken. Two independent reviewers screened items for eligibility and extracted data about the studies, participants, interventions, and outcomes. A single reviewer extracted data to quantify impacts of sport participation, classified as favorable, insignificant, or unfavorable. RESULTS: 164 studies involving 11,642 participants were included. Most studies (128/164) used a cross-sectional design. Most participants were men (81%) with physical disability (135/164), and spinal cord injury was the most prevalent underlying health condition (54%). Most studies evaluated a mix of sports (83/164) in a disability-specific context (159/164), with basketball or wheelchair basketball being the most common individual sport (28/164). Physical impairment was the most frequently reported outcome domain (85/334 results). Sports participation impact was classified as 55% favorable, 42% insignificant, and 3% unfavorable. CONCLUSIONS: There were many favorable and few unfavorable outcomes for participation in sport for adults with physical or intellectual disability. More research is needed to address the evidence gaps of gender, health condition, and type of sport, and to use more rigorous research designs to evaluate the effects of sport participation. While new evidence is generated, we suggest adults with physical or intellectual disability be encouraged to engage in sport. REGISTRATION: PROSPERO registration number CRD42018104379.

The application of extracorporeal shock wave therapy on stem cells therapy to treat various diseases.

In the last ten years, stem cell (SC) therapy has been extensively used to treat a range of conditions such as degenerative illnesses, ischemia-related organ dysfunction, diabetes, and neurological disorders. However, the clinical application of these therapies is limited due to the poor survival and differentiation potential of stem cells (SCs). Extracorporeal shock wave therapy (ESWT), as a non-invasive therapy, has shown great application potential in enhancing the proliferation, differentiation, migration, and recruitment of stem cells, offering new possibilities for utilizing ESWT in conjunction with stem cells for the treatment of different systemic conditions. The review provides a detailed overview of the advances in using ESWT with SCs to treat musculoskeletal, cardiovascular, genitourinary, and nervous system conditions, suggesting that ESWT is a promising strategy for enhancing the efficacy of SC therapy for various diseases.

Elaborating the knowledge structure and emerging research trends of physical activity for multiple sclerosis: A bibliometric analysis from 1994 to 2023.

BACKGROUND: Multiple sclerosis is a common inflammatory neurological disease among young adults and is the tenth leading cause of the global burden of disease. Existing common treatments such as pharmacological and palliative therapies do not control the neurodegenerative process or cure multiple sclerosis. Numerous epidemiological surveys, randomised controlled trials, and systematic reviews with meta-analyses support the effects of physical activity on health-related outcomes among patients with multiple sclerosis. Moreover, bibliometric analysis can provide a broad evidence synthesis beyond systematic reviews and meta-analyses, allowing researchers and other stakeholders to obtain a one-stop overview of this research field. Therefore, this bibliometric analysis aims to provide insight into the knowledge structure of the field of physical activity for multiple sclerosis over the past three decades, and to predict emerging research trends. METHODS: This study strictly complied with step-by-step guidelines of bibliometric analysis, combining performance analysis and science mapping. Four indexes from the Web of Science Core Collection were selected as data sources, and articles and review articles in the field of physical activity for multiple sclerosis from 1994 to 2023 were included in this analysis. Mircrosoft Excel, RStudio, VOSviewer 1.6.20, and CiteSpace 6.3.R1 (64-bit) Advanced were used to perform performance analysis and science mapping. RESULTS: Over the past three decades, this field published a total of 1,271 documents, with the scientific output showing a rapid upward trend over the past two decades. Robbert W Motl was the most prolific author in this field, with a total of 300 publications. The USA contributed nearly half of the publications in this field (549 documents), and the University of Illinois System was the institution with the highest number of publications (222 documents). Multiple Sclerosis and Related Disorders was the journal that published the highest number of documents in this field (117 documents), while more than a third of this field's publications were included in the category: Clinical Neurology (438 documents). The Reference co-citation analysis identified three main research trends, including shifts in research methodology, changes in health outcomes in randomised controlled trials, and shifts in different types of physical activity interventions. Combining the results from reference co-citation analysis and citation burst analysis, the combination of behaviour change technique and telerehabilitation may be the emerging research trend. CONCLUSION: This bibliometric analysis identifies rapid growth in the field of physical activity for multiple sclerosis over the past two decades. Moreover, the combination of performance analysis and science mapping provides insight into knowledge structure in this field and informed future research trends for researchers and the relevant stakeholders.
