Introduction: Restless legs syndrome (RLS) is a common non-motor symptom in Parkinson's disease (PD), but its pathogenesis remains unclear. This study aimed to explore the potential neural substrates of RLS in a large sample of patients with PD.

Methods: A total of 42 patients with PD with RLS and 124 patients with PD without RLS were prospectively recruited at our hospital between February 2019 and October 2020 and underwent structural and resting-state functional magnetic resonance imaging. Differences between the two patient groups were assessed using voxel-based morphometry and functional connectivity analysis. PD duration, Part III of the Movement Disorder Society's Unified Parkinson's Disease Rating Scale (MDS-UPDRS-III) score, and levodopa equivalent daily dose were treated as covariates.

Results: Patients with PD with RLS had significantly larger gray matter volume in the bilateral posterior cingulate cortex than patients with PD without RLS (FDR-adjusted P < 0.05). Compared to patients without RLS, those with RLS had significantly lower functional connectivity between the left central opercular cortex and the bilateral precentral gyri and postcentral gyri (FDR-adjusted P < 0.001).

Conclusion: Our study provides the first evidence that in patients with PD, RLS is associated with significantly larger gray matter volume in the posterior cingulate cortex and lower resting-state functional connectivity within the sensorimotor network. Our results may help clarify the pathophysiology of RLS in PD and identify possible therapeutic targets.

Introduction: There is increasing prevalence of single-use flexible laryngoscopes in Otolaryngology. This study aims to quantify and compare the environmental outcomes of single-use disposable flexible laryngoscopes (SUD-Ls) and reusable flexible laryngoscope (R-Ls).

Methods: The ISO 14040 standardized Life Cycle Assessment (LCAs) was utilized to estimate the environmental footprint of SUD-L and R-L.

Patients with obstructive sleep apnea (OSA), restless legs syndrome (RLS), or both may exhibit varied manifestations of depressive and anxiety symptomatology, reflecting the complex interplay between sleep disturbances, neurotransmitter imbalances, and psychosocial stressors in these often overlapping conditions. The aim of this study was to compare depressive and anxiety symptomatology, insomnia severity, and sleepiness in these conditions. Patients were enrolled and subdivided into those with OSA, RLS, and OSA + RLS.

Objective: Through resting state functional magnetic resonance imaging (rs-fMRI) we evaluate the spontaneous brain activity changes of maintenance hemodialysis (MHD) patients with restless legs syndrome (RSL) and analyzed the imaging features and related mechanisms of RLS in patients with MHD.

Method: We select 27 MHD patients with RLS and 27 patients without RSL matched by age, gender, cognitive function. Both groups underwent neuropsychological tests and MRI scans.

Post-operative transesophageal echocardiography (TEE) is standard of care to evaluate for residual disease and quality of surgical repair. The residual lesion score (RLS) as defined by the pediatric heart network explored the impact of residual lesions on outcomes using discharge transthoracic echocardiogram (TTE). In tetralogy of fallot with pulmonary stenosis (TOF/PS), the residual right ventricular outflow tract (RVOT) gradient is one marker of quality of repair.
