Enhancing Privacy-Preserving Cancer Classification with Convolutional Neural Networks.

Precision medicine significantly enhances patients prognosis, offering personalized treatments. Particularly for metastatic cancer, incorporating primary tumor location into the diagnostic process greatly improves survival rates. However, traditional methods rely on human expertise, requiring substantial time and financial resources.

α-Synuclein Oligomers in Skin Biopsies Predict the Worsening of Cognitive Functions in Parkinson's Disease: A Single-Center Longitudinal Cohort Study.

α-synuclein oligomers within synaptic terminals of autonomic fibers of the skin reliably discriminate Parkinson's disease (PD) patients from healthy controls. Nonetheless, the prognostic role of oligomers for disease progression is unknown. We explored whether α-synuclein oligomers evaluated as proximity ligation assay (PLA) score may predict the worsening of cognitive functions in patients with Parkinson's disease.

Sarcopenia, low muscle strength, cognitive functions, and quality of life in parkinsonian syndromes.

Objectives: Parkinsonian syndromes are disabling neurodegenerative diseases resulting in reduced muscle function/performance and sarcopenia, but clinical manifestations could be systemic, including deterioration of cognitive function. As studies have reported an association between muscle dysfunction and cognitive decline yet no information on these syndromes is available, we investigated the relationship between sarcopenia, its components, and cognitive function, fatigue, and quality of life (QoL).

Methods: Consecutive patients affected by parkinsonian syndromes were assessed for the presence of sarcopenia using the European Working Group on Sarcopenia in Older People-2 algorithm: low strength (handgrip strength: <27 kg [men]; <16 kg [women]) and low appendicular skeletal muscle index by impedance (<7.

Facial expressions and identities recognition in Parkinson disease.

Parkinson's Disease (PD) is associated with motor and non-motor symptoms. Among the latter are deficits in matching, identification, and recognition of emotional facial expressions. On one hand, this deficit has been attributed to a dysfunction in emotion processing.

An Optimized U-Net for Unbalanced Multi-Organ Segmentation.

Medical practice is shifting towards the automation and standardization of the most repetitive procedures to speed up the time-to-diagnosis. Semantic segmentation repre-sents a critical stage in identifying a broad spectrum of regions of interest within medical images. Indeed, it identifies relevant objects by attributing to each image pixels a value representing pre-determined classes.

Clinical correlates of serum 25-hydroxyvitamin D in Parkinson's disease.

Background: Parkinson's disease (PD) patients have lower levels of serum 25-hydroxyvitamin D (25(OH)D) than the general population. Previous studies have suggested a negative association between 25(OH)D and clinical features of PD, but the data are inconsistent.

Materials And Methods: We conducted a cross-sectional, observational study.

Finding a new therapeutic approach for no-option Parkinsonisms: mesenchymal stromal cells for progressive supranuclear palsy.

Background: The trophic, anti-apoptotic and regenerative effects of bone marrow mesenchymal stromal cells (MSC) may reduce neuronal cell loss in neurodegenerative disorders.

Methods: We used MSC as a novel candidate therapeutic tool in a pilot phase-I study for patients affected by progressive supranuclear palsy (PSP), a rare, severe and no-option form of Parkinsonism. Five patients received the cells by infusion into the cerebral arteries.

Dementia in Parkinson's disease: Is male gender a risk factor?

Background: The rates of cognitive decline in patients with Parkinson's disease (PD) are higher than in the general population. Age and disease duration have been associated with increasing rates of dementia in PD. However, the role of other factors including gender has been poorly investigated.

Long-term cognitive follow-up of Parkinson's disease patients with impulse control disorders.

This study investigated cognitive functions in Parkinson's disease (PD) patients with impulse control disorders (ICDs) and aimed to identify possible predictors of behavioral outcome. In this longitudinal cohort study, 40 PD outpatients with ICDs and 40 without, were matched for sex, age at PD onset, age and disease duration at cognitive assessment. All patients had two neuropsychological assessments at least 2 years apart (mean, 3.
