Efficacy and safety of safinamide in Parkinson's disease patients with motor fluctuations without levodopa dosage escalation over 18 weeks: KEEP study.

This multicentre, prospective, single-arm study evaluated safinamide as add-on therapy to levodopa in Korean patients with Parkinson's disease (PD) with motor fluctuations with ≥ 1.5 h of "off" time daily, who took levodopa ≥ 3 times/day (n = 199). Baseline levodopa and dopamine agonist doses were maintained without escalation during the 18-week treatment period.

Role of Peroxisome Proliferator-Activated Receptor α-Dependent Mitochondrial Metabolism in Ovarian Cancer Stem Cells.

Peroxisome proliferator-activated receptors (PPARs), including PPAR-α, PPAR-β/δ, and PPAR-γ, are involved in various cellular responses, including metabolism and cell proliferation. Increasing evidence suggests that PPARs are closely associated with tumorigenesis and metastasis. However, the exact role of PPARs in energy metabolism and cancer stem cell (CSC) proliferation remains unclear.

Mechanism of Action and Pharmacokinetics of Approved Bispecific Antibodies.

Bispecific antibodies represent a significant advancement in therapeutic antibody engineering, offering the ability to simultaneously target two distinct antigens. This dual-targeting capability enhances therapeutic efficacy, especially in complex diseases, such as cancer and autoimmune disorders, where drug resistance and incomplete target coverage are prevalent challenges. Bispecific antibodies facilitate immune cell engagement and disrupt multiple signaling pathways, providing a more comprehensive treatment approach than traditional monoclonal antibodies.

Taltirelin Hydrate in Patients with Ataxia Due to Spinocerebellar Degeneration.

Objective: We conducted this study to assess the efficacy and safety of taltirelin hydrate (TH) in spinocerebellar degeneration (SCD).

Methods: Patients were randomly assigned to either the taltirelin group (5 mg orally, twice daily) or the control group. The primary endpoint was changes in the Korean version of Scale for the Assessment and Rating of Ataxia (K-SARA) scores at 24 weeks.

Clinical Characteristics of Patients with De Novo Parkinson's Disease and a Positive Family History.

: A family history of Parkinson's disease (PD) is an important risk factor for developing PD. Because only a few studies have investigated the clinical characteristics of PD patients based on family history, this study compared the clinical characteristics of PD patients with and without a family history of PD. : The study involved 356 patients with de novo PD.

Restless Legs Syndrome Affects Sleep in de novo Parkinson's Disease Patients.

Background: Restless legs syndrome (RLS) is common in Parkinson's disease (PD) patients and can affect the motor symptoms and non-motor symptoms (NMSs) of PD patients.

Objective: This study aimed to identify the clinical factors affected by RLS in patients with PD.

Methods: We included 369 de novo PD patients.

Differences in Cognitive Trajectories of Dementia: Comparison of Alzheimer's Disease Dementia and Dementia with Lewy Bodies in a Korean Patient Cohort.

Introduction: Prediction of the dementia progression is important for patient management. We aimed to investigate the cognitive trajectories of Alzheimer's disease dementia (ADD) and dementia with Lewy bodies (DLB) according to the initial structural change measured by comprehensive visual rating scales (CVRS).

Methods: We retrospectively included the patients who initially visited the Dementia Clinic of Chonnam National University Hospital between 2010 and 2012.

BBT-877, a Novel Autotaxin Inhibitor, Abrogates Drug Resistance in Epithelial Ovarian Cancer Stem Cells.

Background/aim: Cancer stem cells (CSCs) contribute significantly to the poor prognosis of patients with epithelial ovarian cancer (EOC) due to their roles in drug resistance and tumor metastasis. Autotaxin (ATX) plays a pivotal role in the maintenance of the CSC-like properties of EOC tumors. BBT-877 is a novel ATX inhibitor used in clinical treatment of idiopathic pulmonary fibrosis.

ATN Classification and Clinical Progression of the Amyloid-Negative Group in Alzheimer's Disease Neuroimaging Initiative Participants.

Alzheimer's disease has recently been classified using three biological markers (amyloid [A], tau [T], and neurodegeneration [N]) to help elucidate its progression. We aimed to investigate whether there were differences between cognitive function and the clinical dementia symptoms over time relative to the ATN classification in the amyloid-negative group. In the Alzheimer's Disease Neuroimaging Initiative (ADNI) cohort, 310 participants who underwent all the tests required for ATN classification were enrolled.

Restless legs syndrome affects sleep in de novo Parkinson's disease patients.

Restless legs syndrome (RLS) is common in Parkinson's disease (PD) patients and can affect the motor symptoms and non-motor symptoms (NMSs) of PD patients. The aim of this study was to identify the clinical factors affected by RLS in patients with PD. We included 369 de novo PD patients.

A Case Report of Pseudotumor Cerebri Syndrome with a Huge Retroperitoneal Cyst.

: Aside from primary pseudotumor cerebri syndrome (PTCS) with an unknown etiology (i.e., idiopathic intracranial hypertension), which typically occurs in association with obesity, several conditions including cerebral venous abnormalities, drug use, and hormonal imbalance may be a secondary cause of PTCS.

Clinical value of vestibulo-ocular reflex in the differentiation of spinocerebellar ataxias.

The diagnosis of spinocerebellar ataxia (SCA) currently depends upon genetic testing. Although genetic testing for SCA is highly specific, clinical parameters for the differentiation of SCAs are still insufficient. We aimed to assess the vestibulo-ocular reflex (VOR) parameters of various SCA subtypes to determine whether they have substantial value in differential diagnosis.

Clinical analysis in patients with hereditary spastic paraplegia.

Background: To analyze the clinical phenotype of hereditary spastic paraplegia (HSP) caused by mutations (SPG11-HSP).

Methods: Among the 17 patients with sporadic HSP who performed whole exome sequencing analysis, six were diagnosed with SPG11-HSP. The clinical and radiologic findings and the results of the electrodiagnostic and neuropsychologic tests were reviewed retrospectively.

Older adult-onset Alexander disease with atypical clinicoradiological features: a case report.

Alexander disease (AxD) is a rare autosomal dominant astrogliopathy caused by mutations in the gene encoding for glial fibrillary acidic protein. AxD is divided into two clinical subtypes: type I and type II AxD. Type II AxD usually manifests bulbospinal symptoms and occurs in the second decade of life or later, and its radiologic features include tadpole-like appearance of the brainstem, ventricular garlands, and pial signal changes along the brainstem.

Deep learning-based personalised outcome prediction after acute ischaemic stroke.

Background: Whether deep learning models using clinical data and brain imaging can predict the long-term risk of major adverse cerebro/cardiovascular events (MACE) after acute ischaemic stroke (AIS) at the individual level has not yet been studied.

Methods: A total of 8590 patients with AIS admitted within 5 days of symptom onset were enrolled. The primary outcome was the occurrence of MACEs (a composite of stroke, acute myocardial infarction or death) over 12 months.

Mesenchymal stem cell spheroids alleviate neuropathic pain by modulating chronic inflammatory response genes.

Chronic neuropathic pain is caused by dysfunction of the peripheral nerves associated with the somatosensory system. Mesenchymal stem cells (MSCs) have attracted attention as promising cell therapeutics for chronic pain; however, their clinical application has been hampered by the poor survival and low therapeutic efficacy of transplanted cells. Increasing evidence suggests enhanced therapeutic efficacy of spheroids formed by three-dimensional culture of MSCs.

Movement Disorders Associated With Cerebral Artery Stenosis: A Nationwide Study.

Background: Studies of secondary movement disorder (MD) caused by cerebrovascular diseases have primarily focused on post-stroke MD. However, MD can also result from cerebral artery stenosis (CAS) without clinical manifestations of stroke. In this study, we aimed to investigate the clinical characteristics of MD associated with CAS.
