Falls in Huntington's Disease: A Cross‐Sectional Analysis of Clinical Features and Potential Contributors

Movement Disorders Clinical Practice, EarlyView.
Abstract Background Falls occur across all stages of Huntington's disease (HD) and are associated with poor quality of life and injury. However, there is limited information on falls in HD. Objective The aim was to investigate the clinical features potentially associated with falls in HD. Methods We conducted a cross‐sectional, analytical observational

Altered Cerebrospinal Fluid Tryptophan–Kynurenine Pathway Metabolism in Multiple System Atrophy

Movement Disorders, EarlyView.
Abstract Background Alterations in tryptophan–kynurenine (TRP‐KYN) metabolism, which is associated with neuroinflammation, remain unclear in multiple system atrophy (MSA). Objective The aim was to investigate cerebrospinal fluid (CSF) TRP metabolites in MSA and their associations with other biomarkers.

Ecosystem retrogression enhances cross‐domain microbial stability and increases the genetic potential for nutrient cycling

mLife, EarlyView.
Abstract Ecosystem retrogression drives nutrient depletion, reduced productivity, and profound reorganization of soil microbial communities. Using amplicon sequencing and genome‐resolved metagenomics, we examined how cross‐domain microbial networks and functional gene potential respond to long‐term phosphorus and nitrogen limitation along the well ...

Training Deep Learning Based Dynamic MR Image Reconstruction Using Synthetic Fractals

Magnetic Resonance in Medicine, EarlyView.
ABSTRACT Purpose To investigate whether synthetically generated fractal data can be used to train deep learning (DL) models for dynamic MRI reconstruction, thereby avoiding the privacy, licensing, and availability limitations associated with cardiac MR training datasets.

Seed co‐occurrence caused by shared frugivores leaves a long‐lasting signal in the spatial co‐occurrence among plants

Oikos, EarlyView.
By dispersing seeds, frugivorous animals affect spatial co‐occurrence of plants, ultimately influencing plant community dynamics. Frugivorous animals are intrinsically involved in plant community dynamics, by dispersing seeds of fleshy‐fruited plants and influencing their spatial co‐occurrence.

Hypovitaminosis D in acute inpatient cancer rehabilitation: Prevalence, predictors, and practical implications

PM&R, EarlyView.
Abstract Background Hypovitaminosis D is associated with adverse health outcomes, including increased mortality in patients with cancer. Although vitamin D insufficiency (23%–72%) and deficiency (20%–71%) are common among patients admitted to inpatient rehabilitation, their prevalence and predictors in cancer‐specific inpatient rehabilitation ...

Disease–Drug–Drug Interaction of Imatinib in COVID‐19 ARDS: A Pooled Population Pharmacokinetic Analysis

CPT: Pharmacometrics &Systems Pharmacology, Volume 14, Issue 3, Page 583-595, March 2025.
ABSTRACT Prior pharmacokinetic (PK) analysis revealed that increased alpha‐1‐acid glycoprotein (AAG) levels are associated with decreased imatinib unbound fraction in coronavirus disease 2019 (COVID‐19) patients. This study aimed to investigate the PK of total and unbound concentrations of imatinib and the metabolite N‐desmethyl imatinib in ...

The Size Problem of Bootstrap Tests when the Null isNon- or Semiparametric El problema del tamaño de los contrastes bootstrap cuando la hipótesis nula es No- o semiparamétrica

Revista Colombiana de Estadística, 2010
In non- and semiparametric testing, the wild bootstrap is a standard method for determining the critical values of tests. If the null hypothesis is also semi- or nonparametric, then we know that at least asymptotically oversmoothing is necessary in the ...
