Objective: To describe demographic and clinical characteristics in a group of Parkinson's disease (PD) patients with non-motor fluctuations (NMF) and to evaluate the management of medications proposed to treat NMF.
Methods: Three hundred and three PD patients (mean age, 66 ± 10.3 years; mean disease duration, 10.1 ± 6.5 years) were enrolled. Each patient was interviewed in a non-directed fashion about the main NMF manifestations, i.e. dysautonomic, mental, and sensory symptoms. Both groups of patients with and without NMF were compared. Dysautonomia, motor fluctuations, age, disease duration, and LEDD were included in a multiple regression to determine which were predictive of NMF.
Results: NMF were found in 57 (19%) patients, mean age 65 ± 10.1 years, mean age at onset of PD 53.7 ± 10.9 years, mean disease duration 12.5 ± 6.9 years. NMF occurred on average 9.8 ± 7.7 years after the onset of PD. Fifty patients (86%) with NMF had also MF and 10 (21%) had PDD. Twenty-five (44%) patients suffered from sensory, 28 (49%) from autonomic and 25 (44%) from neuropsychiatric symptoms. Both disease and L-Dopa treatment durations, and LEDD were significantly higher in NMF patient's group. Motor fluctuations (p = 0.0016) and presence of dysautonomia (p = 0.007) were found to be two independent predictors of NMF.
Conclusion: The development of new instruments to assess NMF is crucial for optimized management of advanced PD.

Introduction: Since the dawn of the new millennium, Candida species have been increasingly implicated as a cause of both healthcare-associated as well as opportunistic yeast infections, due to the widespread use of indwelling medical devices, total parenteral nutrition, systemic corticosteroids, cytotoxic chemotherapy, and broad-spectrum antibiotics. Candida tropicalis is a pathogenic Candida species associated with considerable morbidity, mortality, and drug resistance issues on a global scale.

Neovascular age-related macular degeneration and diabetic macular edema are leading causes of vision-loss evoked by retinal neovascularization and vascular leakage. The glycoprotein microfibrillar-associated protein 4 (MFAP4) is an integrin αβ ligand present in the extracellular matrix. Single-cell transcriptomics reveal MFAP4 expression in cell-types in close proximity to vascular endothelial cells including choroidal vascular mural cells and retinal astrocytes and Müller cells.

Objective: The objective of this study is to assess the predictive utility of perioperative P-wave parameters in patients with paroxysmal atrial fibrillation (PAF) undergoing catheter ablation, and to develop a predictive model using these parameters.
Methods: A total of 213 patients with PAF undergoing catheter ablation were retrospectively analyzed. P-wave parameters were measured within 3 days preoperatively and on the day postoperatively to determine their predictive significance for postoperative PAF recurrence.
