The effects of sex and load on quantifying the bilateral force deficit during an upper body Wingate test.

Introduction: The bilateral deficit (BLD) is a reduction in the amount of force during a bilateral task vs. the total force from the unilateral limbs performing the same task. We quantified the BLD during an upper body Wingate Anaerobic Test (WAnT) and evaluated the influence of sex and load on the BLD in force.

Sex-related differences in corticospinal excitability outcome measures of the biceps brachii during a submaximal elbow flexor contraction.

The purpose of this study was to investigate the effects of sex, muscle thickness, and subcutaneous fat thickness (SFT) on corticospinal excitability outcome measures of the biceps brachii. Eighteen participants (10 males and 8 females) completed this study. Ultrasound was used to assess biceps brachii muscle thickness and the overlying SFT.

Neuromechanical Differences between Pronated and Supinated Forearm Positions during Upper-Body Wingate Tests.

Arm-cycling is a versatile exercise modality with applications in both athletic enhancement and rehabilitation, yet the influence of forearm orientation remains understudied. Thus, this study aimed to investigate the impact of forearm position on upper-body arm-cycling Wingate tests. Fourteen adult males (27.

Adapting the Gamified Educational Networking Online Learning Management System to Test a Decentralized Simulation-Based Education Model to Instruct Paramedics-in-Training on the Emergency Intraosseous Access and Infusion Skill.

Intraosseous (IO) access and infusion is a safe and rapid alternative to intravenous access in obtaining vascular access for administering fluids and drugs. Healthcare professionals, such as primary and advanced care paramedics, use IO access and infusion in emergency circumstances where peripheral intravenous routes are inaccessible. IO access skills require hands-on training, which can be done remotely if the participants have access to simulation, instructions, guidance, and feedback.

The Effects of Load, Crank Position, and Sex on the Biomechanics and Performance during an Upper Body Wingate Anaerobic Test.

Introduction: The upper body Wingate Anaerobic Test (WAnT) is a 30-s maximal effort sprint against a set load (percentage of body mass). However, there is no consensus on the optimal load and no differential values for males and females, even when there are well-studied anatomical and physiological differences in muscle mass for the upper body. Our goal was to describe the effects of load, sex, and crank position on the kinetics, kinematics, and performance of the upper body WAnT.

Nursing Informatics: Competency Challenges for Nursing Faculty.

Nursing is the largest workforce in health care with nurses increasingly required to work with digital health technologies. However, despite the adoption of nursing informatics in Australia in the mid-1980s, nursing graduates are not being adequately equipped to use these technologies in a way that benefits the profession and improves patient care. Using a scoping review approach, this paper presents an analysis of contemporary published literature and describes the barriers to faculty engagement with digital health technologies in undergraduate nursing education.

Adolescent Residential Addiction Treatment In The US: Uneven Access, Waitlists, And High Costs.

Drug overdose deaths among adolescents are increasing in the United States. Residential treatment facilities are one treatment option for adolescents with substance use disorders, yet little is known about their accessibility or cost. Using the Substance Abuse and Mental Health Services Administration's treatment locator and search engine advertising data, we identified 160 residential addiction treatment facilities that treated adolescents with opioid use disorder as of December 2022.

Neuroanatomy of the late Cretaceous Thescelosaurus neglectus (Neornithischia: Thescelosauridae) reveals novel ecological specialisations within Dinosauria.

Ornithischian dinosaurs exhibited a diversity of ecologies, locomotory modes, and social structures, making them an ideal clade in which to study the evolution of neuroanatomy and behaviour. Here, we present a 3D digital reconstruction of the endocranial spaces of the latest Cretaceous neornithischian Thescelosaurus neglectus, in order to interpret the neuroanatomy and paleobiology of one of the last surviving non-avian dinosaurs. Results demonstrate that the brain of Thescelosaurus was relatively small compared to most other neornithischians, instead suggesting cognitive capabilities within the range of extant reptiles.

The Use of Elastic Resistance Bands to Reduce Dynamic Knee Valgus in Squat-Based Movements: A Narrative Review.

Unlabelled: An elastic band wrapped around the distal thighs has recently been proposed as a method for reducing dynamic knee valgus (medial movement of the knee joint in the frontal/coronal plane) while performing squats. The rationale behind this technique is that, by using an external force to pull the knees into further knee valgus, the band both exaggerates the pre-existing movement and provides additional local proprioceptive input, cueing individuals to adjust their knee alignment. If these mechanisms are true, then elastic bands might indeed reduce dynamic knee valgus, which could be promising for use in injury prevention as excessive knee valgus may be associated with a greater risk of sustaining an ACL rupture and/or other knee injuries.

The Perceived Effectiveness of Various Forms of Feedback on the Acquisition of Technical Skills by Advanced Learners in Simulation-Based Health Professions Education.

Simulation-based health professions education (SBHPE) is a valuable approach for healthcare professionals to develop and refine technical skills in a safe environment. Feedback plays a crucial role in the acquisition of these skills, but little research has explored the effectiveness of augmented (knowledge of results (KR) and knowledge of performance (KP) versus intrinsic feedback types for advanced learners. Therefore, this study aimed to determine what type of feedback is perceived to be most effective by advanced learners when acquiring complex technical skills in SBHPE.

Defining the Nature of Augmented Feedback for Learning Intraosseous Access Skills in Simulation-Based Health Professions Education.

In the field of health professions education, acquiring technical skills involves three stages: 1) receiving instructions, 2) engaging in practice, and 3) receiving feedback. Simulation serves as a valuable tool that encompasses all three stages, enhancing the effectiveness of health professions education. This work focuses on feedback, which can be categorized as intrinsic (perceived by the learner through their senses) or augmented (provided by an external perspective).

Sex Difference in Lower-limb Electromyography and Kinematics when Using Resistance Bands during a Barbell Back Squat.

The aim of this study was to compare the muscle activity of the gluteus medius (GMe), gluteus maximus (GMa), biceps femoris (BF), vastus lateralis (VL), vastus medialis (VM) and erector spinae (ES) as well as medial knee displacement (MKD) while using varying stiffness resistance bands (red: 1.68 kg; black: 3.31 kg; gold: 6.

Two weeks of arm cycling sprint interval training enhances spinal excitability to the biceps brachii.

The present study aimed to investigate whether a 2-wk arm cycling sprint interval training (SIT) program modulated corticospinal pathway excitability in healthy, neurologically intact participants. We employed a pre-post study design with two groups: ) an experimental SIT group and ) a nonexercising control group. Transcranial magnetic stimulation (TMS) of the motor cortex and transmastoid electrical stimulation (TMES) of corticospinal axons were used at baseline and post-training to provide indices of corticospinal and spinal excitability, respectively.

Challenging the Myth of the Digital Native: A Narrative Review.

Background And Aims: Nurses are increasingly engaging with digital technologies to enhance safe, evidence-based patient care. Digital literacy is now considered a foundational skill and an integral requirement for lifelong learning, and includes the ability to search efficiently, critique information and recognise the inherent risk of bias in information sources. However, at many universities, digital literacy is assumed.

Aqueous Cold Sintering of Li-Based Compounds.

Aqueous cold sintering of two lithium-based compounds, the electrolyte LiLaZrAlO (LLZAO) and cathode material LiCoO (LCO), is reported. For LLZAO, a relative density of ∼87% was achieved, whereas LCO was sintered to ∼95% with 20 wt % LLZAO as a flux/binder. As-cold sintered LLZAO exhibited a low total conductivity (10 S/cm) attributed to an insulating grain boundary blocking layer of LiCO.

Multiple pathways to herbivory underpinned deep divergences in ornithischian evolution.

The extent to which evolution is deterministic is a key question in biology, with intensive debate on how adaptation and constraints might canalize solutions to ecological challenges. Alternatively, unique adaptations and phylogenetic contingency may render evolution fundamentally unpredictable. Information from the fossil record is critical to this debate, but performance data for extinct taxa are limited.

Substance use disorder treatment and technology access among people who use drugs in rural areas of the United States: A cross-sectional survey.

Purpose: To evaluate how technology access affected substance use disorder (SUD) treatment prior to COVID-19 for people who use drugs in rural areas.

Methods: The Rural Opioid Initiative (January 2018-March 2020) was a cross-sectional study of people with prior 30-day injection drug or nonprescribed opioid use from rural areas of 10 states. Using multivariable mixed-effect regression models, we examined associations between participant technology access and SUD treatment.

Hacking Intraosseous Infusion Skills Training With 3D Printing: maxSIMIO Drilling System.

Intraosseous (IO) infusion is an alternative way to access the vascular system to administer drugs and fluids, which is particularly helpful when the commonly used peripheral intravenous route is inaccessible. The IO procedure can be done using a drill that involves disinfecting the area, landmarking the insertion point, seating the needle in a firm and stable position in the bone, and then delivering a smooth fluid flush. However, in the current medical training landscape, access to commercially available IO drills such as the Arrow® EZ-IO® Power Driver (EZ-IO; Teleflex, Morrisville, North Carolina, United States) is difficult, especially for rural and remote areas, due to the high costs.

Development of Simple and Advanced Adult Proximal Tibia Simulators for a Decentralized Simulation-Based Education Model to Teach Paramedics-in-Training the Intraosseous Infusion Procedure.

Introduction During the COVID-19 pandemic, public health had advised practicing social distancing which led to the temporary shutdown of simulation laboratories or centralized simulation-based education model, shared spaces that healthcare workers such as paramedics use to train on important hands-on clinical skills for the job. One such skill is intraosseous (IO) access and infusion, the delivery of fluids and medication through the marrow or medullary cavity of the bone which provides fast and direct entry into the central venous system. This skill is critical in emergencies when peripheral access is not immediately available.

A novel rhesus macaque model of Huntington's disease recapitulates key neuropathological changes along with motor and cognitive decline.

We created a new nonhuman primate model of the genetic neurodegenerative disorder Huntington's disease (HD) by injecting a mixture of recombinant adeno-associated viral vectors, serotypes AAV2 and AAV2.retro, each expressing a fragment of human mutant () into the caudate and putamen of adult rhesus macaques. This modeling strategy results in expression of mutant huntingtin protein (mHTT) and aggregate formation in the injected brain regions, as well as dozens of other cortical and subcortical brain regions affected in human HD patients.
