Hyposmia correlates with axial signs and gait disorder in Parkinson's disease: an Italian Olfactory Identification Test study.

Background: Olfactory dysfunction is a non-motor symptom and an important biomarker of Parkinson's disease (PD) because of its high prevalence (> 90%). Whether hyposmia correlates with motor symptoms is unclear. In the present study, we aim to investigate the relationship between olfactory impairment with both motor and non-motor features and disease variables (disease duration, stage, and severity).

Evaluation and Treatment of Dysphagia in Public and Private Intensive Care Units (ICUs) in Greece.

 Dysphagia is a significant but underrecognized clinical issue in the intensive care unit (ICU), and it is associated with various complications. Despite its clinical importance, there is limited research and no Greek ICU-specific guidelines for managing dysphagic patients. Additionally, only a few ICUs in Greece have dysphagia specialists, specifically speech-language pathologists (SLPs) providing their expertise.

The effect of vitamin D and magnesium supplementation on clinical symptoms and serum inflammatory and oxidative stress markers in patients with COVID-19: a structured summary of a study protocol for a randomized controlled trial.

Objectives: This study aims to evaluate the effect of vitamin D and magnesium supplementation on clinical symptoms and serum inflammatory and oxidative stress markers in patients with COVID-19.

Trial Design: This study is a 4-arm randomized, double-blind, placebo-controlled clinical trial with a factorial design and the intervention period is 3 weeks.

Participants: This study is conducted on COVID-19 patients admitted to the Shahid Mohammadi hospital in Bandar Abbas, Iran, who are eligible for inclusion in the study.

Impulse Control Disorders and Levodopa-Induced Dyskinesias in Parkinson's Disease: Pulsatile versus Continuous Dopaminergic Stimulation.

Background: Dopaminergic medications in Parkinson's disease (PD) are usually associated with the development of both levodopa-induced dyskinesias (LID) and impulse control and repetitive behavior disorders (ICRB).

Objective: To assess the prevalence and the severity of ICRB in a cohort of moderate and advanced PD patients and to investigate the potential interplay between ICRB, LID and dopaminergic therapies.

Methods: 117 PD patients were consecutively recruited.

T2*-weighted MRI values correlate with motor and cognitive dysfunction in Parkinson's disease.

Brain iron load is one of the main neuropathologic hallmarks of Parkinson's disease (PD). Previous studies indicated that iron in the substantia nigra (SN) is related to disease duration and motor impairment. We explore, through a cross-sectional study, the association between brain iron distribution, evaluated by T2*-weighted magnetic resonance imaging (T2*), and clinical features in a cohort of patients with PD.
