Optimal sigmoid function models for analysis of transspinal evoked potential recruitment curves recorded from different muscles.

Recruitment input-output curves of transspinal evoked potentials that represent the net output of spinal neuronal networks during which cortical, spinal and peripheral inputs are integrated as well as motor evoked potentials and H-reflexes are used extensively in research as neurophysiological biomarkers to establish physiological or pathological motor behavior and post-treatment recovery. A comparison between different sigmoidal models to fit the transspinal evoked potentials recruitment curve and estimate the parameters of physiological importance has not been performed. This study sought to address this gap by fitting eight sigmoidal models (Boltzmann, Hill, Log-Logistic, Log-Normal, Weibull-1, Weibull-2, Gompertz, Extreme Value Function) to the transspinal evoked potentials recruitment curves of soleus and tibialis anterior recorded under four different cathodal stimulation settings.

Translational Outcomes Project in Neurotrauma (TOP-NT) Pre-Clinical Consortium Study: A Synopsis.

Traumatic brain injury (TBI) has long been a leading cause of death and disability, yet research has failed to successfully translate findings from the pre-clinical, animal setting into the clinic. One factor that contributes significantly to this struggle is the heterogeneity observed in the clinical setting where patients present with injuries of varying types, severities, and comorbidities. Modeling this highly varied population in the laboratory remains challenging.

Sex Differences in Long COVID.

Importance: A substantial number of individuals worldwide experience long COVID, or post-COVID condition. Other postviral and autoimmune conditions have a female predominance, but whether the same is true for long COVID, especially within different subgroups, is uncertain.

Objective: To evaluate sex differences in the risk of developing long COVID among adults with SARS-CoV-2 infection.

Dual Biological Role and Clinical Impact of De Novo Chromatin Activation in Chronic Lymphocytic Leukemia.

Previous studies have reported that chronic lymphocytic leukemia (CLL) shows a de novo chromatin activation pattern as compared to normal B cells. Here, we explored whether the level of chromatin activation is related to the clinical behavior of CLL. We identified that in some regulatory regions, increased de novo chromatin activation is linked to clinical progression whereas, in other regions, it is associated with an indolent course.

Depressive Symptoms and Amyloid Pathology.

Importance: Depressive symptoms are associated with cognitive decline in older individuals. Uncertainty about underlying mechanisms hampers diagnostic and therapeutic efforts. This large-scale study aimed to elucidate the association between depressive symptoms and amyloid pathology.

Prevalence and Risk Factors for Medial Meniscus Ramp Lesions in the Setting of Pediatric Anterior Cruciate Ligament Injuries: A Systematic Review and Meta-analysis.

Background: Medial meniscus ramp lesions (MMRLs) are commonly associated with anterior cruciate ligament (ACL) injuries and may increase the risk of graft failure after ACL reconstruction (ACLR) if undiagnosed or left untreated. Although MMRLs have been extensively reported in adults, there are limited studies describing them in pediatric patients undergoing ACLR. The purpose of this study was to perform a systematic review and meta-analysis to determine the pooled prevalence of and risk factors for MMRLs in pediatric patients with ACL injuries.

Initial clinical experience with [Lu]Lu-PNT2002 radioligand therapy in metastatic castration-resistant prostate cancer: dosimetry, safety, and efficacy from the lead-in cohort of the SPLASH trial.

Introduction: SPLASH (NCT04647526) is a multicenter phase III trial evaluating the efficacy and safety of [Lu]Lu-PNT2002 radioligand therapy in metastatic castration-resistant prostate cancer (mCRPC). This study leveraged a lead-in phase to assess tissue dosimetry and evaluate preliminary safety and efficacy, prior to expansion into a randomized phase. Here we report those results.

Current practices in MRI screening in early onset scoliosis.

Purpose: Early onset scoliosis (EOS) has traditionally been an indication for MRI because of its association with neural axis abnormalities (NAAs). Because these abnormalities are often clinically silent and concerns regarding sedation in young children are growing, routine MRI for EOS is debated. This study investigates the current practices of EOS MRI screening among surgeons in the Pediatric Spine Study Group (PSSG).

Durability of response of UGN-101: Longitudinal follow up of multicenter study.

Purpose: UGN-101, a reverse thermal mitomycin gel for upper tract instillation, recently became the first FDA approved treatment for upper tract urothelial carcinoma (UTUC). However, the durability of UGN-101 treatment has not been well described. Here we present long term outcomes from our multi-institutional cohort for patients who initially responded to treatment.

Background: The contribution of MTHFR and TP53 genetic variants to breast carcinoma (BC) susceptibility has been examined, but their findings have been inconclusive. This work is designed to explore the potential roles of the MTHFR (rs1801131, rs1801133) and TP53 (rs1042522) variants with increased risk of BC using genetic and bioinformatic approaches.

Methods: This work included a total of 242 female participants [142 BCE patients and 100 healthy controls].

Use of Claims to Assess Outcomes and Treatment Effects in the Evolut Low Risk Trial.

Background: Food and Drug Administration-mandated postmarket studies for transcatheter aortic valve replacement in low-risk populations plan to use passively collected registry data linked to claims for long-term follow-up out to 10 years. Therefore, it is critically important to understand the validity of these claims-based end points. We sought to evaluate the ability of administrative claims with () codes to identify trial-adjudicated end points and reproduce treatment comparisons of aortic valve replacement in the Evolut Low Risk Trial.

Manipulating Fano Coupling in an Opto-Thermoelectric Field.

Fano resonances in photonics arise from the coupling and interference between two resonant modes in structures with broken symmetry. They feature an uneven and narrow and tunable lineshape and are ideally suited for optical spectroscopy. Many Fano resonance structures have been suggested in nanophotonics over the last ten years, but reconfigurability and tailored design remain challenging.

Return to Sport and Graft Failure Rates After Primary Anterior Cruciate Ligament Reconstruction With a Bone-Patellar Tendon-Bone Versus Hamstring Tendon Autograft: A Systematic Review and Meta-analysis.

Background: Anterior cruciate ligament (ACL) tears are frequent injuries in athletes that often require surgical reconstruction so that patients may return to their previous levels of performance. While existing data on patient-reported outcomes are similar between bone-patellar tendon-bone (BTB) and hamstring tendon (HT) autografts, the literature regarding return to sport (RTS), return to previous levels of sport activity, and graft failure rate remains limited.

Purpose: To compare rates of RTS, return to previous activity levels, and graft retears among athletes undergoing primary ACL reconstruction using a BTB versus HT autograft.

C-Reactive Protein Changes in Adult and Pediatric People With Cystic Fibrosis During Treatment of Pulmonary Exacerbations.

Objective: Although studies have examined changes in C-reactive protein (CRP) during pulmonary exacerbations (PEX) in people with cystic fibrosis (PwCF), few have evaluated CRP profiles across age groups. Here, we characterize age-related CRP responses to PEX treatment.

Methods: We measured CRP concentrations at the beginning and end of intravenous (IV) antibiotic therapy for PEX in 100 pediatric and 147 adult PwCF at 10 US CF Centers.

Comparing quantitative imaging biomarker alliance volumetric CT classifications with RECIST response categories.

Purpose: To assess agreement between CT volumetry change classifications derived from Quantitative Imaging Biomarker Alliance Profile cut-points (ie, QIBA CTvol classifications) and the Response Evaluation Criteria in Solid Tumors (RECIST) categories.

Materials And Methods: Target lesions in lung, liver, and lymph nodes were randomly chosen from patients in 10 historical clinical trials for various cancers, ensuring a balanced representation of lesion types, diameter ranges described in the QIBA Profile, and variations in change magnitudes. Three radiologists independently segmented these lesions at baseline and follow-up scans using 2 software tools.

DISCOntinuation of disease-modifying therapies in MS: The DISCOMS extension trial.

Background: In the DISCOMS (DISCOntinuation of disease-modifying therapies (DMTs) in multiple sclerosis (MS)) randomized clinical trial, we could not demonstrate that discontinuing MS DMTs in older, stable adults was not inferior to continuing DMTs. Relapses were rare in both groups, and most new disease activity was one to two new brain magnetic resonance imaging (MRI) lesions unassociated with clinical changes.

Objective/aims: Describe results of the DISCOMS extension study.

Lack of TRIC-B dysregulates cytoskeleton assembly, trapping β-catenin at osteoblast adhesion sites.

The trimeric intracellular cation channel B (TRIC-B), encoded by TMEM38B, is a potassium (K) channel present in the endoplasmic reticulum membrane, where it counterbalances calcium (Ca) exit. Lack of TRIC-B activity causes a recessive form of the skeletal disease osteogenesis imperfecta (OI), namely OI type XIV, characterized by impaired intracellular Ca flux and defects in osteoblast (OB) differentiation and activity. Taking advantage of the OB-specific Tmem38b knockout mouse (Runx2Cre;Tmem38b; cKO), we investigated how the ion imbalance affects the osteogenetic process.
