Newton-type methods for REML estimation in genetic analysis of quantitative traits

Journal of Computational Methods in Sciences and Engineering, 2008
Robust and efficient optimization methods for variance component estimation using Restricted Maximum Likelihood (REML) models for genetic mapping of quantitative traits are considered. We show that the standard Newton-AI scheme may fail when the optimum is located at one of the constraint boundaries, and we introduce different approaches to remedy this

The majority of elite and professional athletes return to the preinjury level of activity after ACL reconstruction: A systematic review and meta‐analysis

Knee Surgery, Sports Traumatology, Arthroscopy, EarlyView.
Abstract Purpose To compare return to play (RTP), time to RTP, level of RTP, and anterior cruciate ligament (ACL) graft failure among elite and professional athletes from different sports after anterior cruciate ligament reconstruction (ACLR). Methods The PubMed, Embase and Cochrane Library databases were searched to identify potentially relevant ...

ChatGPT provides accurate and safe responses to patient questions on hip arthroscopy, while completeness remains variable: A systematic review and single‐arm meta‐analysis

Knee Surgery, Sports Traumatology, Arthroscopy, EarlyView.
Abstract Purpose Large language models, such as ChatGPT, are increasingly used by patients seeking information on hip arthroscopy (HAS) and femoroacetabular impingement (FAI). Despite their linguistic fluency, the accuracy, completeness and safety of procedure‐specific patient information remain unclear.

Radiotherapy‐Induced Otitis Media With Effusion in Nasopharyngeal Carcinoma: A Meta‐Analysis

The Laryngoscope, EarlyView.
This meta‐analysis of eight studies comprising 582 NPC patients provides the first quantitative synthesis of radiotherapy‐induced otitis media with effusion (OME), demonstrating a significant overall risk difference of 0.18 (95% CI: −0.06 to 0.42, p < 0.0001) in OME naive ears.

Genetic parameters and genetic and phenotypic trends of performance traits of equines from the Brazilian Army

Revista Brasileira de Zootecnia, 2012
The objective of this research was to compare the magnitude of genetic parameters (coefficients of heritability and genetic correlation) as estimated by the Restricted Maximum Likelihood (REML) method and Bayesian Inference, and to estimate the genetic ...

Temporal Interference Stimulation Modulates Resting State Functional Connectivity of Motor Circuit in Parkinson's Disease

Movement Disorders, EarlyView.
Abstract Background Transcranial temporal interference stimulation (TIs) targeting the subthalamic nucleus (STN) is a novel noninvasive neuromodulation approach with potential to improve motor symptoms in Parkinson's disease (PD). However, its underlying neuroimaging mechanisms remain unclear.

Speech and Deep Brain Stimulation in Parkinson's Disease, Essential Tremor, and Dystonia: A Systematic Review and Meta‐analysis

Movement Disorders, EarlyView.
Abstract Deep brain stimulation (DBS) effectively treats motor symptoms in movement disorders but often compromises speech through incompletely defined mechanisms. We conducted a PROSPERO‐registered systematic review and meta‐analysis of publications through August 2024 (CRD42024527738).

Functional diversity in agricultural landscapes: evidence of long‐term clustering and multi‐scale effects of land use on avian communities

Oikos, EarlyView.
Functional diversity (FD) is an essential community property connecting biodiversity, ecosystem functioning, and conservation objectives. In agricultural landscapes, avian communities, which play key functional roles, are facing large‐scale biodiversity erosion, largely due to land‐use changes.
