A cross-sectional study: correlation of forehead morphology and dentoskeletal malocclusion in Chinese people.

BACKGROUND: The lateral profile is an important indicator of facial attractiveness. This study explored the general characteristics of the forehead profile and protrusion, and their relationship with related factors in structure and development. METHODS: Four hundred fourteen Chinese participants in the Yangtze River Delta region were involved. Including 206 males (17.15 ± 7.68 years old) and 208 females (18.35 ± 8.06 years old); 94 children (8.54 ± 2.21 years old, ranging from 4 to 12 years old), 166 adolescents (14.83 ± 1.50 years old, ranging from 13 to 17 years old), and 154 adults (25.52 ± 4.89, 18 years or older). The frontal section of the forehead was used to explore its shape. The straight distance between the vertical line of the FH plane through the nasal root point and its parallel line, which is tangential to the forehead, indicates the forehead prominence. Frontal sinus width was measured using the method described by Mahmood. RESULTS: The general shape of the forehead was straight and slightly bulged near the eyebrow arch in males but rounder in females. The average forehead protrusion in males was higher than that in females in adults. Significant differences in forehead protrusion between the dentoskeletal classifications and growth phases were notable. Frontal protrusion significantly correlated with frontal sinus depth, especially in males, adults, Class I, and those whose convex points were located in the lower section of the forehead. CONCLUSIONS: Age, race, and sex affect the forehead protrusion and frontal sinus width. Forehead protrusion may be an indicator of dentoskeletal deformities in the early stage. And dentoskeletal deformities may impair the correlation between the frontal sinuses and forehead protrusion during development. TRIAL REGISTRATION: This retrospective, cross-sectional study was reviewed and approved by the Research Ethical Committee (T2020008), and registered at ClinicalTrial.gov with an identified number (ChiCTR2100041913).

Self-Sensing Cementitious Composites with Hierarchical Carbon Fiber-Carbon Nanotube Composite Fillers for Crack Development Monitoring of a Maglev Girder.

In view of high-performance, multifunctional, and low-carbon development of infrastructures, there is a growing demand for smart engineering materials, making infrastructures intelligent. This paper reports a new-generation self-sensing cementitious composite (SSCC) incorporated with a hierarchically structured carbon fiber (CF)-carbon nanotube (CNT) composite filler (CF-CNT), which is in situ synthesized by directly growing CNT on CF. Various important factors including catalyst, temperature, and gas composition are considered to investigate their kinetic and thermodynamic influence on CF-CNT synthesis. The reciprocal architecture of CF-CNT not only alleviates the CNT aggregation, but also significantly improves the interfacial bonding between CF-CNT and matrix. Due to the synergic and spatially morphological effects of CF-CNT, that is, the formation of widely distributed multiscale reinforcement networks, SSCCs with CF-CNTs exhibit high mechanical properties and electrical conductivity as well as excellent self-sensing performances, particularly enhanced sensing repeatability. Moreover, the SSCCs with CF-CNTs are integrated into a full-scale maglev girder to devise a smart system for crack development monitoring. The system demonstrates high sensitivity and fidelity to capture the initiation of cracks/damage, as well as progressive and sudden damage events until the complete failure of the maglev girder, indicating its considerable potential for structural health monitoring of infrastructures.

A hospital-based retrospective study: early recognition of neuronal surface antibodies by clinical manifestations and CSF inflammation indicators in patients with unexplained epilepsy.

BACKGROUND: There is a lack of actual and comprehensive data on the detection rate of neuronal surface antibodies in patients with unexplained epilepsy in China. Thus, we attempted to analyze the differences in clinical manifestations, cerebrospinal fluid (CSF) characteristics, seizure types and other aspects of antibody-positive and negative patients, to identify suspected antibody-positive epilepsy patients. METHODS: In total, 137 inpatients with unexplained epilepsy were consecutively included, and neuronal surface antibodies (NSAbs) were detected by serological and/or CSF evaluations. The clinical features and seizure characteristics were analyzed between the NSAb-positive and negative patients. In addition, patients were divided into four groups based on CSF and blood antibody titers. CSF cell count and protein content were analyzed in relation to antibody titers. RESULTS: There were 45 (32.8%) patients tested positive for antibodies. Multivariate analyses revealed that age, mental status changes or memory deterioration, CSF protein, CSF cell count, treatment, days of hospitalization, outcome, duration of symptoms before hospitalization, status epilepticus, and number of antiepileptic drugs were significantly associated with the NSAb-positive group and changes in inflammatory indicators in routine CSF analysis were associated with antibody titers. CONCLUSIONS: A relatively high proportion of patients with unexplained epilepsy have positive NSAbs. Patients with the above clinical characteristics need to be highly suspected of NSAbs positivity and should be tested for antibodies in time to assist treatment. The decrease of CSF cell count and protein content has suggestive value for the decrease of antibody titer, which should be evaluated in the follow-up.

Response of human periodontal ligament to orthodontic force using superb microvascular imaging.

INTRODUCTION: Remodeling of the periodontal ligament (PDL) during orthodontic tooth movement is closely related to the vascularity of the PDL, which has not been thoroughly investigated in humans. This study aimed to measure the width and vascular parameters of human PDL using superb microvascular imaging for the first time. METHODS: Patients aged 18-25 years were selected for participation. The intervention was randomly allocated from the maxillary canines to the first molars on both sides using 50 g or 150 g of force. The width and vascular parameters of the PDL were measured using superb microvascular imaging at different time intervals (baseline, 30 minutes, and 1, 3, 7, and 14 days). RESULTS: Before the intervention, the width of the PDL ranged from 0.14 to 0.25 mm, and the vascular index ranged from 9.40% to 13.54%. After applying orthodontic forces, the cervical and middle PDL widths increased. The vascular index decreased slightly in 30 minutes, decreased to a minimum value after 1 day, increased to the maximum in 3-7 days, and returned to baseline values in 14 days. The values of other vascular parameters showed similar trends. CONCLUSIONS: The width and vascular parameters of the PDL changed slightly after force application, underwent changes in the period of reconstruction for 3-7 days, and eventually returned to baseline in 14 days.

External validation and comparison of two prediction models for seizure recurrence after the withdrawal of antiepileptic drugs in adult patients.

OBJECTIVE: The models currently available for predicting the risk of seizure recurrence after antiepileptic drug (AED) withdrawal in adult epilepsy patients include the prediction model developed by Lamberink et al (Lamberink model, 2017) and the Medical Research Council prediction model (MRC model, 1993). However, there was no external validation for the two models. The purpose of this study was to perform an independent external validation and a comparison of the Lamberink model and the MRC model in adult patients. METHODS: The study population was recruited from the Wenzhou Epilepsy Follow-up Registry Database (WEFURD). All the predictors of the Lamberink and MRC models and the occurrence of seizure recurrence in the participants were collected based on the WEFURD. Participants' predicted probabilities of seizure recurrence were obtained by a Web-based tool and the prognostic index formula. The external validation of the Lamberink model and the MRC model were quantified by discrimination, calibration, and decision curve analysis (DCA). RESULTS: Of 212 patients, 126 (59.4%) had seizure recurrence after AED withdrawal. The Lamberink 2-year model, the Lamberink 5-year model, the MRC 1-year model, and the MRC 2-year model had areas under the curve of 0.71 (95% confidence interval [CI] = 0.64-0.78), 0.68 (95% CI = 0.60-0.76), 0.60 (95% CI = 0.50-0.69), and 0.58 (95% CI = 0.50-0.66), respectively. Additionally, the Lamberink 2-year model had a significantly better integrated discrimination improvement than the MRC 2-year model (P < .001). Regarding calibration, the Lamberink 2-year model (P = .121) and the MRC 1-year model (P = .264) were well calibrated, but the Lamberink 5-year model (P = .022) and the MRC 2-year model (P = .008) were not. In the DCA, the Lamberink 2-year model performed well at threshold probabilities of 30%-65%. SIGNIFICANCE: This external validation shows that the Lamberink 2-year model might be more accurate and has greater clinical benefit than others for guiding drug withdrawal in adult epilepsy clinics.

Comparison of the performance of two depression rating scales in patients with epilepsy in southern China.

OBJECTIVE: The aim of this study was to evaluate and compare the performance of the Chinese version of the Neurological Disorder Depression Inventory for Epilepsy (CNDDI-E) with that of the depression subscale of the Hospital Anxiety and Depression Scale (C-HADS-D) as screening tools for depression in the same patients with epilepsy (PWE). METHODS: A total of 213 consecutive PWE were evaluated. Receiver operating characteristic (ROC) analysis was performed using the C-NDDI-E and C-HADS-D as predictors and the Chinese version of the Mini International Neuropsychiatric Interview (C-MINI) as the gold standard. RESULTS: The area under the curve (AUC) for the C-NDDI-E was 0.870, and the optimal cutoff score was >11 (sensitivity 85.71%, specificity 79.78%); for the C-HADS-D, the AUC was 0.804, and the optimal cutoff score was >5 (sensitivity 85.71%, specificity 62.36%). The AUC for the C-NDDI-E was larger than the AUC for the C-HADS-D, but the comparison of the AUCs revealed no significant differences (P = 0.1444). CONCLUSION: Our findings indicate that the C-NDDI-E and C-HADS-D have high validity and support the use of these screening tools for depression in PWE. Moreover, the C-NDDI-E is a better screening scale for diagnosing depression than the C-HADS-D according to the results of this study.

Comparison of the performance of suicide ideation scales in adult patients with epilepsy in China.

OBJECTIVE: The aims of this study were to evaluate and compare the performance of the Chinese version of the Suicide Ideation Scale-Current (SSI-C) and the Suicide Ideation Scale-Worst (SSI-W) as suicide ideation screening tools in patients with epilepsy (PWE). METHODS: A consecutive sample of Chinese adult PWE recruited from a tertiary hospital completed the SSI-C and SSI-W and the suicidality module of the Chinese version of the Mini International Neuropsychiatric Interview (MINI) Plus 5.0.0. RESULTS: A total of 260 consecutive PWE were recruited. The area under the curve (AUC) for the SSI-C was 0.831, and the optimal cutoff score was >1 (sensitivity 73%, specificity 91%); for the SSI-W, the AUC was 0.958, and the optimal cutoff score was >2 (sensitivity 94.6%, specificity 87.4%). The AUC for the SSI-W was larger than that for the SSI-C, and the two-factor structure was considered significant. CONCLUSION: Our results showed that the SSI-C and SSI-W had good validity as suicidal ideation screening tools in PWE in southern China and can be recommended for clinical suicidal ideation screening. The SSI-W is a better suicidal ideation screening tool than the SSI-C according to the results of our study.

Risk factors for suicidal tendency in adult patients with epilepsy in China.

OBJECTIVE: The major cause of premature mortality in people with epilepsy (PWE) is suicide. Actual data on the risk of suicidal tendency in adult PWE in China are scarce. In our study, associations between possible risk factors and suicidal tendency in adult PWE in China were investigated. METHODS: People with epilepsy (n = 251) were recruited, and their demographic and clinical characteristics were evaluated. Suicide risk was examined using the suicidality module (SM) of the Mini International Neuropsychiatric Interview (MINI) Plus Chinese Version 5.0.0. RESULTS: Suicidal tendency was present in 36 (14.3%) of the 251 PWE. On the basis of the results of univariate analyses, family relationship (P < 0.001), age at epilepsy onset (P = 0.037), seizure-free period (P = 0.041), seizures/month (P = 0.015), depressive disorders (P < 0.001), and number of antiepileptic drugs (AEDs) (P = 0.017) were associated with suicidal tendency. Multivariate analysis revealed that moderate or poor family relationships (odds ratio (OR): 6.468, 95% confidence interval (CI): 2.418-17.300) and depressive disorders (OR: 3.548, 95% CI: 1.575-7.995) were associated with high odds of suicidal tendency. CONCLUSION: Suicidal tendency is common among adult PWE. This study reveals that family relationships and depressive disorders are independent risk factors for suicidal tendency among adult PWE. Therefore, while maintaining treatment of epilepsy, more attention should be directed to the social support and mental state of PWE to prevent suicide.

Validation of the Chinese version of the Scale for Suicide Ideation-Worst in adult patients with epilepsy.

OBJECTIVE: The aim of this study was to validate the Chinese version of the Scale for Suicide Ideation-Worst (SSI-W) for screening suicide ideation in Chinese adult patients with epilepsy (PWE). METHOD: A consecutive sample of Chinese adult PWE from a tertiary hospital completed the SSI-W and the suicidality module of the Chinese version of the Mini International Neuropsychiatric Interview (MINI) Plus 5.0.0. RESULTS: A total of 269 PWE completed the scales. According to the MINI, 59 patients (21.9%) had suicidal ideation. The Cronbach's α coefficient for the SSI-W was 0.96. Receiver operating characteristic (ROC) curve analysis showed that the area under the curve (AUC) for the SSI-W was 0.957 (95% confidence interval [CI] = 0.935-0.980). With a cutoff score of 2 points, the SSI-W demonstrated the best psychometric properties: a sensitivity of 95.8%, a specificity of 87.3%, a positive predictive value (PPV) of 56.7%, and a negative predictive value (NPV) of 99.0%. The scores for items 11 (Reason for attempt) and 18 (Final acts) were not significantly different (p > 0.05) in patients with suicidal ideation, while the scores for the other items were significantly different between these groups of patients. CONCLUSION: The Chinese version of the SSI-W proved to be a reliable and effective assessment tool for screening suicidal ideation in Chinese adult PWE.

Reliability and validity of the Chinese version of the Patient Health Questionnaire 9 (C-PHQ-9) in patients with epilepsy.

OBJECTIVE: The aim of this study was to evaluate the clinical reliability and validity of the Chinese version of the Patient Health Questionnaire 9 (C-PHQ-9) in patients with epilepsy. METHODS: A total of 213 consecutive adult patients with epilepsy were evaluated. Receiver operating characteristic (ROC) analysis was performed using C-PHQ-9 and Chinese version of Patient Health Questionnaire 2 (C-PHQ-2) as predictors and the Mini International Neuropsychiatric Interview Plus Version 5.0.0 as the gold standard. RESULTS: The C-PHQ-9 was easily understood and quickly finished by the patients. According to the gold standard, the prevalence of current major depressive disorder in this population was 16.4%. Cronbach's α coefficient for the C-PHQ-9 was 0.860. The ROC analysis showed an area under the curve (AUC) of 0.888 (95% confidence interval [CI] = 0.838-0.927). At a cutoff score of >6, the C-PHQ-9 had a sensitivity of 82.86%, a specificity of 84.27%, a positive predictive value of 50.9%, and a negative predictive value of 96.2%. The C-PHQ-2 at a cutoff score of >1 resulted in the greatest balance of sensitivity and specificity (77.14% and 75.28%, respectively). CONCLUSION: Our findings support a high reliability and validity for the C-PHQ-9 as a screening tool for the detection of current major depression in Chinese patients with epilepsy.

Validation of the Chinese version of the Hamilton Rating Scale for Depression in adults with epilepsy.

OBJECTIVE: This study aimed to validate the Chinese version of the 17-item Hamilton Rating Scale for Depression (C-HRSD-17) for use in adult patients with epilepsy (PWE). METHODS: A consecutive sample of Chinese adult PWE from a tertiary hospital was examined using the C-HRSD-17 and the Mini International Neuropsychiatric Interview (MINI) Plus Chinese Version 5.0.0. RESULTS: A total of 191 PWE completed the assessment of depression. According to the MINI, thirty patients (15.7%) had current major depressive disorder (MDD). The Cronbach's α coefficient for the C-HRSD-17 was 0.832. Receiver operating characteristic (ROC) analysis showed an area under the curve (AUC) of 0.983 (95% CI = 0.968-0.998). With a cutoff score of 9, the C-HRSD-17 demonstrated the best psychometric properties, with a sensitivity of 96.7%, a specificity of 93.8%, a positive predictive value (PPV) of 74.4%, and a negative predictive value (NPV) of 99.3%. CONCLUSION: The C-HRSD-17 proved to be a valid and reliable assessment tool, with a cutoff score of 9 for screening of current MDD in Chinese adult PWE.

Sinusoidal phase-modulating laser diode interferometer for wide range displacement measurement.

A sinusoidal phase-modulating laser diode interferometer for wide range displacement measurement is proposed. To realize wide range displacement measurement, a signal processing method utilizing a look-up table to estimate the dynamic value of the effective sinusoidal phase-modulating depth is detailed, and the error caused by the residual amplitude modulation and the effective sinusoidal phase-modulating depth in wide range displacement measurement can be eliminated. It is discussed that the extended measurement range depends on the monotone intervals of several specific functions. The simulation and experimental results prove that the sinusoidal phase-modulating laser diode interferometer with the proposed method could realize centimeter level displacement measurement range.

Sinusoidal phase-modulating interferometer with ellipse fitting and a correction method.

In a sinusoidal phase-modulating interferometer, sinusoidal modulation of the phase of the laser or the reference wave is necessary. However, modulation of the phase also involves an intensity modulation of the light, which leads to a measurement error if conventional signal processing is used. In addition, the error of modulation depth and the phase delay of demodulation also increase the measurement error. A novel signal processing, with ellipse fitting and a correction method, is proposed. Numerical simulation results and experimental results prove that the novel signal processing can compensate for the measurement error caused by the intensity modulation, the error of modulation depth, and the phase delay of demodulation.

Late-onset cerebellar ataxia and a new frameshift L2HGDH mutation in a Chinese adult with L-2-hydroxyglutaric aciduria: a case report.

L-2-Hydroxyglutaric aciduria (L2HGA) is a rare, autosomal recessive neurometabolic disease, which presents with elevated L-2-hydroxyglutarate acid. Generally, L2HGA appear as slowly progressing central nervous system function deterioration during infancy, and a rapid progression in adulthood is uncommon for the syndrome's classic phenotype.

Environmental microbial diversity and water pollution characteristics resulted from 150 km coastline in Quanzhou Bay offshore area.

As a typical transitional area between the land and sea, the offshore area is subjected to the triple synergistic pressure from the ocean, land, and atmosphere at the same time, and has obvious characteristics such as complex and diverse chemical, physical, and biological processes, coupled and changeable environmental factors, and sensitive and fragile ecological environment. With the deepening of the urbanization process, the offshore area has gradually become the final receptions of pollutants produced by industry, agriculture, and service industries, and plays a key role in the global environmental geochemical cycle of pollutants. In this study, the Quanzhou Bay offshore area was selected as the research object. Sediment and water samples were collected from 8 sampling points within about 150 km of coastline in the Quanzhou Bay offshore area. 16s rDNA high-throughput sequencing method was used to investigate the variation rule of microbial diversity in the offshore area, and multi-parameter water quality analysis was carried out at the same time. The results showed that the distribution characteristics of microbial communities and water quality in the Quanzhou Bay offshore area showed significant differences in different latitudes and longitudes. This difference is closely related to the complexity of offshore area. This study can provide scientific support for protecting and improving the ecological environment of offshore areas.

Realize Generative Yet Complete Latent Representation for Incomplete Multi-View Learning.

In multi-view environment, it would yield missing observations due to the limitation of the observation process. The most current representation learning methods struggle to explore complete information by lacking either cross-generative via simply filling in missing view data, or solidative via inferring a consistent representation among the existing views. To address this problem, we propose a deep generative model to learn a complete generative latent representation, namely Complete Multi-view Variational Auto-Encoders (CMVAE), which models the generation of the multiple views from a complete latent variable represented by a mixture of Gaussian distributions. Thus, the missing view can be fully characterized by the latent variables and is resolved by estimating its posterior distribution. Accordingly, a novel variational lower bound is introduced to integrate view-invariant information into posterior inference to enhance the solidative of the learned latent representation. The intrinsic correlations between views are mined to seek cross-view generality, and information leading to missing views is fused by view weights to reach solidity. Benchmark experimental results in clustering, classification, and cross-view image generation tasks demonstrate the superiority of CMVAE, while time complexity and parameter sensitivity analyses illustrate the efficiency and robustness. Additionally, application to bioinformatics data exemplifies its practical significance.

Ubiquitin-specific proteases: From biological functions to potential therapeutic applications in gastric cancer.

Deubiquitination, a post-translational modification regulated by deubiquitinases, is essential for cancer initiation and progression. Ubiquitin-specific proteases (USPs) are essential elements of the deubiquitinase family, and are overexpressed in gastric cancer (GC). Through the regulation of several signaling pathways, such as Wnt/ß-Catenin and nuclear factor-κB signaling, and the promotion of the expression of deubiquitination- and stabilization-associated proteins, USPs promote the proliferation, metastasis, invasion, and epithelial-mesenchymal transition of GC. In addition, the expression of USPs is closely related to clinicopathological features, patient prognosis, and chemotherapy resistance. USPs therefore could be used as prognostic biomarkers. USP targeting small molecule inhibitors have demonstrated strong anticancer activity. However, they have not yet been tested in the clinic. This article provides an overview of the latest fundamental research on USPs in GC, aiming to enhance the understanding of how USPs contribute to GC progression, and identifying possible targets for GC treatment to improve patient survival.

Long Non-Coding RNAs in Drug Resistance of Gastric Cancer: Complex Mechanisms and Potential Clinical Applications.

Gastric cancer (GC) ranks as the third most prevalent malignancy and a leading cause of cancer-related mortality worldwide. However, the majority of patients with GC are diagnosed at an advanced stage, highlighting the urgent need for effective perioperative and postoperative chemotherapy to prevent relapse and metastasis. The current treatment strategies have limited overall efficacy because of intrinsic or acquired drug resistance. Recent evidence suggests that dysregulated long non-coding RNAs (lncRNAs) play a significant role in mediating drug resistance in GC. Therefore, there is an imperative to explore novel molecular mechanisms underlying drug resistance in order to overcome this challenging issue. With advancements in deep transcriptome sequencing technology, lncRNAs-once considered transcriptional noise-have garnered widespread attention as potential regulators of carcinogenesis, including tumor cell proliferation, metastasis, and sensitivity to chemo- or radiotherapy through multiple regulatory mechanisms. In light of these findings, we aim to review the mechanisms by which lncRNAs contribute to drug therapy resistance in GC with the goal of providing new insights and breakthroughs toward overcoming this formidable obstacle.

Meta-analysis of randomized controlled trials of the effects of synbiotics, probiotics, or prebiotics in controlling glucose homeostasis in non-alcoholic fatty liver disease patients.

Background: Probiotics, prebiotics, and synbiotics have been suggested as a possible therapy for non-alcoholic fatty liver disease (NAFLD). However, their efficacy in improving blood glucose levels in NAFLD patients remains uncertain. Objective: The aim of this study was to assess the effects of supplementation with probiotics, prebiotics, or synbiotics on fasting blood glucose (FBG) levels in NAFLD patients. Methods: We searched PubMed, Web of Science, and Google Scholar for relevant trials published up to March 2024. Out of 3369 identified studies, 24 randomized controlled trials (RCTs) were included. Results: Probiotic, prebiotic, or synbiotic supplementation substantially reduced FBG (n = 23; standard mean difference (SMD) = -0.17; 95% confidence interval (CI): -0.30, -0.03; P = 0.02), fasting insulin levels (n = 12; SMD = -0.28; 95% CI: -0.49, -0.07; P = 0.01), and homeostatic model assessment for insulin resistance (HOMA-IR; n = 14; SMD = -0.28; 95% CI: -0.47, -0.09; P = 0.004). However, glycosylated hemoglobin (HbA1c; n = 3; SMD = -0.17; 95% CI: -0.48, 0.13; P = 0.27) was not significantly affected. The FBG-decreasing effect diminished as the body mass index (BMI) of volunteers increased in the baseline. Additionally, the number of probiotic strains and geographic region were shown to significantly affect FBG levels. Conclusion: This meta-analysis indicates that supplementation with probiotics, prebiotics, or synbiotics may aid in controlling glucose homeostasis in patients with NAFLD.

Efficacy of Wearable low-intensity pulsed Ultrasound treatment in the Movement disorder in Parkinson's disease (the SWUMP trial): protocol for a single-site, double-blind, randomized controlled trial.

BACKGROUND: Parkinson's disease (PD) is a progressive, neurodegenerative illness marked by the loss of dopaminergic neurons, causing motor symptoms. Oral levodopa replacement therapy remains the gold standard in the treatment of PD. It is, nevertheless, a symptomatic treatment. There is currently no effective treatment for PD. Therefore, new therapies for PD are highly desirable. Low-intensity pulsed ultrasound (LIPUS) has been shown to improve behavioral functions in PD animal models. It is a new type of neuromodulation approach that combines noninvasiveness with high spatial precision. The purpose of this study is to establish a new clinical protocol for LIPUS in the treatment of movement disorders in patients with PD. METHODS: This protocol is a single-site, prospective, double-blind, randomized controlled trial (RCT). Forty-eight participants with clinically confirmed PD will be randomly allocated to one of two groups: LIPUS group or sham group. All of the participants continue to use pharmacological therapy as a fundamental treatment. The primary outcome is the difference between groups from baseline to 4 months in the change in the Unified Parkinson's Disease Rating Scale (UPDRS) motor score (part III). The secondary outcomes include the rating scales such as the Mini-Mental State Examination (MMSE), and other three rating scales, and medical examinations including high-density electroencephalography (hdEEG) and functional magnetic resonance imaging (fMRI). The primary safety outcome will be assessed at 4 months, and adverse events will be recorded. DISCUSSION: This study represents the clinical investigation into the efficacy of therapeutic LIPUS in the treatment of PD for the first time. If LIPUS is determined to be effective, it could offer a practical and innovative means of expanding the accessibility of ultrasound therapy by using a wearable LIPUS device within a home setting.
