Return of individual research results to participants with and at risk for Parkinson's disease.

In a prospective, remote natural history study of 277 individuals with (60) and genetically at risk for (217) Parkinson's disease (PD), we examined interest in the return of individual research results (IRRs) and compared characteristics of those who opted for versus against the return of IRRs. Most ( = 180, 65%) requested sharing of IRRs with either a primary care provider, neurologist, or themselves. Among individuals without PD, those who requested sharing of IRRs with a clinician reported more motor symptoms than those who did not request any sharing (mean (SD) 2.

Semi automatic quantification of REM sleep without atonia in natural sleep environment.

Polysomnography, the gold standard diagnostic tool in sleep medicine, is performed in an artificial environment. This might alter sleep and may not accurately reflect typical sleep patterns. While macro-structures are sensitive to environmental effects, micro-structures remain more stable.

A Model for Predicting Severe Intra-Abdominal Adhesions following Prior Cesarean Sections.

Modality-Specific and Amodal Language Processing by Single Neurons.

According to psycholinguistic theories, during language processing, spoken and written words are first encoded along independent phonological and orthographic dimensions, then enter into modality-independent syntactic and semantic codes. Non-invasive brain imaging has isolated several cortical regions putatively associated with those processing stages, but lacks the resolution to identify the corresponding neural codes. Here, we describe the firing responses of over 1000 neurons, and mesoscale field potentials from over 1400 microwires and 1500 iEEG contacts in 21 awake neurosurgical patients with implanted electrodes during written and spoken sentence comprehension.

Methods: In this multicenter retrospective study, children treated with upadacitinib for induction of remission of active UC or IBD-U from 30 centers worldwide were enrolled.

Radiological Changes in the Spinal Cord and Brain of Patients with HTLV-1-Associated Myelopathy/Tropical Spastic Paraparesis (HAM/TSP).

HTLV-1-associated myelopathy/tropical spastic paraparesis (HAM/TSP) is a chronic, progressive neurological disorder and shares many radiological and clinical features with other more prevalent myelopathies. Here, we quantified spinal cord and brain volumes in adults with HAM/TSP in comparison with healthy volunteers (HVs) and individuals diagnosed with relapsing-remitting or progressive multiple sclerosis (RRMS or P-MS). Clinical disability and MRI were assessed in 24 HVs, 43 HAM/TSP subjects, and 46 MS subjects.

Greater Tuberosity Healing Rate and Clinical Results Following RSA Are Similar for Two Fracture-Specific Implant Systems.

Various fracture-specific reverse shoulder arthroplasty (RSA) systems exist on the market. We set out to examine whether the type of prosthesis used and the means of fixation (cemented or non-cemented) influenced the rate of tuberosity healing or the functional outcome of the operation. This retrospective cohort multicenter study included 146 patients who underwent RSA for an acute three- or four-part proximal humerus fracture and had a minimum follow-up of one year.

Safety and Effectiveness of a Novel Liposomal Intra-Articular Lubricant in Symptomatic Knee Osteoarthritis: A First-in-Human Study.

ICG-guided sentinel lymph node biopsy in melanoma is as effective as blue dye: A retrospective analysis.

Introduction: Sentinel lymph node biopsy (SLNB) is a key procedure in the staging and management of melanoma. Traditionally, it is performed using a dual-mapping technique combining a radioactive isotope (RI) and blue dye (BD). Fluorescence-guided surgery with indocyanine green (ICG) has emerged as an alternative tracer, offering potential advantages in real-time visualization and operative efficiency.

Outcomes by Retrospective Eligibility for Maintenance Therapy of Patients With Advanced Urothelial Carcinoma: Post Hoc Analysis of the Phase 3 KEYNOTE-361 Trial.

Introduction: The phase 3 KEYNOTE-361 trial of first-line pembrolizumab with or without chemotherapy versus chemotherapy alone in patients with locally advanced or metastatic urothelial carcinoma (la/mUC) completed enrollment before the approval of postchemotherapy maintenance avelumab for patients without progressive disease. This post hoc analysis evaluated the outcomes of patients who received chemotherapy alone in KEYNOTE-361 by retrospective eligibility for subsequent maintenance therapy.

Patients And Methods: Patients in the chemotherapy alone arm were retrospectively categorized as maintenance eligible (received ≥4 cycles of chemotherapy and did not die or experience disease progression within 10 weeks of chemotherapy completion), maintenance ineligible (received <4 cycles of chemotherapy or had progressive disease or died within 0-10 weeks after completion of ≥4 cycles of chemotherapy), and indeterminate eligibility for maintenance therapy (if neither maintenance eligible or ineligible).

Enhancing cognitive function after traumatic brain injury in male mice: The benefits of running regardless of intervention timing.

The significant benefits of physical activity are well-documented in academic literature, with growing evidence highlighting its positive effects (among others) on memory and cognitive function. Exercise, particularly aerobic activities, has been shown to mitigate neuroinflammatory processes, promote neuronal regeneration, facilitate recovery from cerebral trauma, and reduce the risk of neurodegenerative diseases. Among neurological conditions, traumatic brain injury (TBI) is the most common in individuals under 50, with 80-90 % of cases categorized as mild traumatic brain injury (mTBI).
