Effect of EGCG-Methacrylate-Functionalized Resin Infiltrant on White Spot Lesions: An In Vitro Study.

This study evaluated the color change (ΔE) and penetration depth (PD) of white spot lesions (WSLs) infiltrated with the resin infiltrant (Icon) functionalized with methacrylate epigallocatechin-3-gallate (EGCG). To introduce polymerizable double bonds, EGCG was reacted with methacryloyl chloride (EM). Subsequently, the Icon resin infiltrant (I) was loaded with neat EGCG (IE) or EGCG-methacrylate (IEM) at 2 wt% each.

Validation of the Portuguese version of the Movement Disorder Society non-motor rating scale (MDS-NMS) in Parkinson's disease.

Background: The Movement Disorder Society Non-Motor Rating Scale (MDS-NMS) serves as a comprehensive clinical assessment tool for non-motor symptoms in Parkinson's disease (PD) OBJECTIVES: This study aims to validate the Portuguese version of the MDS-NMS, addressing the critical need for culturally adapted rating scales in Portuguese-speaking populations.

Methods: This multicenter, cross-sectional study engaged native Portuguese-speaking PD patients from 16 Movement Disorders Centers across Portugal and Brazil. We conducted a meticulous translation process into Portuguese, including forward-backward translation and cognitive pretesting.

Access to healthcare: waiting time until the surgical procedure.

Background: Understanding the determinants that limit the population's access to surgical care in health services is highly relevant in order to provide data to support political interventions.

Objective: This study aimed to evaluate the time between diagnosis and elective surgery in adult patients with the longest waiting lists in Brazil; identify the determinants that interfere with access to the health service to perform surgery; and analyze the quality of life after the indicative diagnosis of surgical intervention.

Methods: A cross-sectional study was conducted with adult patients treated at three hospitals in the Southeast, North and South regions of Brazil, from October 2020 to October 2022.

Changes in sensor recorded activity patterns and neuropsychiatric symptoms after deep brain stimulation for Parkinson's disease: 5 case reports.

Background: Effects of subthalamic nucleus deep brain stimulation (STN-DBS) on neuropsychiatric symptoms of Parkinson's disease (PD) remain debated. Sensor technology might help to objectively assess behavioural changes after STN-DBS.

Case Presentation: 5 PD patients were assessed 1 before and 5 months after STN-DBS with the Movement Disorders Society Unified Parkinson's Disease Rating Scale part III in the medication ON (plus postoperatively stimulation ON) condition, the Montreal Cognitive Assessment, the Questionnaire for Impulsive-Compulsive Behaviors in Parkinson's Disease Rating Scale present version, the Hospital Anxiety and Depression Scale and the Starkstein Apathy Scale.
