Running performance in Australopithecus afarensis.

The evolution of bipedal gait is a key adaptive feature in hominids, but the running abilities of early hominins have not been extensively studied. Here, we present physics simulations of Australopithecus afarensis that demonstrate this genus was mechanically capable of bipedal running but with absolute and relative (size-normalized) maximum speeds considerably inferior to modern humans. Simulations predicted running energetics for Australopithecus that are generally consistent with values for mammals and birds of similar body size, therefore suggesting relatively low cost of transport across a limited speed range.

Association between modifiable and nonmodifiable risk factors with paralumbar muscle health in patients with lower back pain.

Background: Prior studies have linked sarcopenia and fat infiltration in paraspinal muscles with lumbar pain, spinal pathology, and adverse postoperative outcomes in lumbar spine surgery. A recent magnetic resonance imaging (MRI)-based method for assessing muscle health, incorporating parameters such as Goutallier Classification (GC) and the Paralumbar Muscle Cross-Sectional Area to Body Mass Index ratio (PL-CSA/BMI), has shown that higher muscle grades correlate with significant improvements in patient-reported outcomes. Despite these advancements, there is limited research on the associations between paralumbar muscle health and factors such as age, BMI, walking tolerability, and spondylolisthesis.

The purpose of this article is to evaluate the ability of computed tomography (CT)-based preoperative templating to accurately predict implant sizes. A total of 724 Stryker MAKO robotic-assisted TKA cases were retrospectively evaluated from a prospectively collected database between January 2020 and October 2023.

ItpCtrl-AI: End-to-end interpretable and controllable artificial intelligence by modeling radiologists' intentions.

Using Deep Learning in computer-aided diagnosis systems has been of great interest due to its impressive performance in the general domain and medical domain. However, a notable challenge is the lack of explainability of many advanced models, which poses risks in critical applications such as diagnosing findings in CXR. To address this problem, we propose ItpCtrl-AI, a novel end-to-end interpretable and controllable framework that mirrors the decision-making process of the radiologist.

Bile acid-induced metabolic changes in the colon promote Enterobacteriaceae expansion and associate with dysbiosis in Crohn's disease.

Bile acids (BAs) affect the growth of potentially pathogenic commensals, including those from the Enterobacteriaceae family, which are frequently overrepresented in inflammatory bowel disease (IBD). BAs are normally reabsorbed in the ileum for recycling and are often increased in the colonic lumina of patients with IBD, including those with Crohn's disease (CD). Here, we investigated the influence of BAs on gut colonization by Enterobacteriaceae.

Profile of Ofatumumab in the Treatment of Multiple Sclerosis: Design, Development and Place in Therapy.

Targeting B cells through monoclonal antibodies against CD20 has emerged as a highly effective strategy in managing disease activity in patients with relapsing forms of multiple sclerosis. This efficacy was initially demonstrated with rituximab and further affirmed with ocrelizumab. Ofatumumab is the first fully human IgG1 monoclonal antibody (mAb) approved for the treatment of MS.

A telerehabilitation program to improve visual perception in children and adolescents with hemianopia consecutive to a brain tumor: a single-arm feasibility and proof-of-concept trial.

Background: Brain tumor in children can induce hemianopia, a loss of conscious vision, profoundly impacting their development and quality of life, yet no effective intervention exists for this pediatric population. This study aimed to explore the feasibility, safety, and potential effectiveness of a home-based audiovisual stimulation in immersive virtual-reality (3D-MOT-IVR) to improve visual function and functional vision.

Methods: In a phase 2a, open-labeled, nonrandomized, single-arm study, conducted from July 2022 to October 2023 (NCT05065268), 10 children and adolescents with stable hemianopia were enrolled to perform 20-min sessions of 3D-MOT-IVR every other day for six weeks from home.

Identifying Demographic and Clinical Determinants of Ischemic Workup in Patients with Heart Failure.

Coronary artery disease (CAD) is a common and treatable cause of heart failure (HF), but ischemic evaluation is often overlooked when evaluating patients with new-onset HF. Here, we sought to discern demographic and clinical predictors of ischemic workup in patients with newly diagnosed HF. A retrospective study of 200 consecutive patients with new-onset HF admitted to our safety-net hospital between 2011 and 2015 was performed.

Single-View Fluoroscopic X-Ray Pose Estimation: A Comparison of Alternative Loss Functions and Volumetric Scene Representations.

Many tasks performed in image-guided procedures can be cast as pose estimation problems, where specific projections are chosen to reach a target in 3D space. In this study, we construct a framework for fluoroscopic pose estimation and compare alternative loss functions and volumetric scene representations. We first develop a differentiable projection (DiffProj) algorithm for the efficient computation of Digitally Reconstructed Radiographs (DRRs) from either Cone-Beam Computerized Tomography (CBCT) or neural scene representations.

Fungal biomarkers in HIV-associated disseminated histoplasmosis: a multicenter diagnostic accuracy study on the Guiana shield.

Methods: We performed a diagnostic accuracy study using frozen primary serum specimens issued from consecutive hospitalized people living with HIV (PLWH) and blindly tested for BDG and GM using Fungitell and PlateliaAspergillus, respectively.

Left of sternum compressions are associated with higher systolic blood pressure than lower half of sternum compressions in cardiac arrest.

Introduction: Limited evidence supports guidelines to perform chest compressions at the lower half of the sternum. Imaging studies suggest this location may obstruct blood flow. Our primary aim was to compare the highest arterial line systolic blood pressure (SBP) during lower-half-of-sternum chest compressions (CC) versus those left-of-sternum, where the left ventricle is more likely located.

Elemental profiling and genome-wide association studies reveal genomic variants modulating ionomic composition in leaves.

The ionome represents elemental composition in plant tissues and can be an indicator of nutrient status as well as overall plant performance. Thus, identifying genetic determinants governing elemental uptake and storage is an important goal for breeding and engineering biomass feedstocks with improved performance. In this study, we coupled high-throughput ionome characterization of leaf tissues with high-resolution genome-wide association studies (GWAS) to uncover genetic loci that modulate ionomic composition in leaves of poplar ().
