Sacroplasty with or without screw fixation for sacral metastatic tumors.

Introduction: Cementation (sacroplasty) with or without ablation has been shown to improve pain and function for patients with sacral metastatic disease. Percutaneous screw fixation with sacroplasty (PSFS) may provide superior outcomes in select patients.

Methods: Thirty patients with sacral metastases who underwent sacroplasty with or without ablation and screw fixation at a single institution were retrospectively reviewed.

Making sense of feelings.

Internal feeling states such as pain, hunger, and thirst are widely assumed to be drivers of behaviours essential for homeostasis and animal survival. Call this the 'causal assumption'. It is becoming increasingly apparent that the causal assumption is incompatible with the standard view of motor action in neuroscience.

Limited information is available regarding the knowledge of Cardiovascular Disease (CVD) risk factors and the actual risk behaviors among African American (AA) older women living in rural areas of Alabama. A pilot study of needs assessment for CVD prevention behaviors was conducted to collect such data from rural AA women. This paper reports the quantitative part of the needs assessment of this pilot study.

Surface and Bulk Stabilization of Silicon Anodes with Mixed-Multivalent Additives: Ca(TFSI) and Mg(TFSI).

Silicon is drawing attention as an emerging anode material for the next generation of lithium-ion batteries due to its higher capacity compared with commercial graphite. However, silicon anions formed during lithiation are highly reactive with binder and electrolyte components, creating an unstable SEI layer and limiting the calendar life of silicon anodes. The reactivity of lithium silicide and the formation of an unstable SEI layer are mitigated by utilizing a mixture of Ca and Mg multivalent cations as an electrolyte additive for Si anodes to improve their calendar life.

Monitoring Structural Changes during Electrochemical Cycling of Solid-Solution Spinel Oxide MgCrVO.

Rechargeable magnesium-ion batteries (MIBs) hold significant promise as an alternative to conventional lithium-ion technology driven by their natural abundance and low-cost, high-energy density, and safety features. Spinel oxides, including MgCrVO, have emerged as a prospective cathode material for MIBs due to their promising combination of capacity, operating potential, and cation mobility. However, the structural evolution, phase stability, and processes of Mg mobility in MgCrVO during electrochemical cycling are poorly understood.

Mixed-Anion Contact Ion-Pair Formation Enabling Improved Performance of Halide-Free Mg-Ion Electrolytes.

Discovery of stable and efficient electrolytes that are compatible with magnesium metal anodes and high-voltage cathodes is crucial to enabling energy storage technologies that can move beyond existing Li-ion systems. Many promising electrolytes for magnesium anodes have been proposed with chloride-based systems at the forefront; however, Cl-containing electrolytes lack the oxidative stability required by high-voltage cathodes. In this work, we report magnesium trifluoromethanesulfonate (triflate) as a viable coanion for Cl-free, mixed-anion magnesium electrolytes.

Auto-Brewery Syndrome and General Anesthesia: A Case Report.

Auto-brewery syndrome (ABS) is a rare condition in which ethanol is endogenously fermented by fungi in the gut following a carbohydrate-rich meal, resulting in intoxication. We present a case of a patient with ABS successfully undergoing general anesthesia for symptomatic wisdom tooth extraction. During previous anesthetics, the patient had experienced postoperative nausea and vomiting (PONV) and awareness under anesthesia.

Quantitative Analysis of Origin of Lithium Inventory Loss and Interface Evolution over Extended Fast Charge Aging in Li Ion Batteries.

During the extreme fast charging (XFC) of lithium-ion batteries, lithium inventory loss (LLI) and reaction mechanisms at the anode/electrolyte interface are crucial factors in performance and safety. Determining the causes of LLI and quantifying them remain an essential challenge. We present mechanistic research on the evolution and interactions of aging mechanisms at the anode/electrolyte interface.

Musculoskeletal Interventional Oncology: A Contemporary Review.

Musculoskeletal interventional oncology is an emerging field that addresses the limitations of conventional therapies for bone and soft-tissue tumors. The field's growth has been driven by evolving treatment paradigms, expanding society guidelines, mounting supportive literature, technologic advances, and cross-specialty collaboration with medical, surgical, and radiation oncology. Safe, effective, and durable pain palliation, local control, and stabilization of musculoskeletal tumors are increasingly achieved through an expanding array of contemporary minimally invasive percutaneous image-guided treatments, including ablation, osteoplasty, vertebral augmentation (with or without mechanical reinforcement via implants), osseous consolidation via percutaneous screw fixation (with or without osteoplasty), tumor embolization, and neurolysis.

Synthesis, structural and electrochemical properties of VO cathode for lithium batteries.

Single-phase three-dimensional vanadium oxide (VO) was synthesized by reduction of VO using a gas stream of ammonia/argon (NH/Ar). The as-synthesized oxide, prepared by this simple gas reduction method was subsequently electrochemically transformed into a disordered rock salt type-"Li3.7V4O9" phase while cycling over the voltage window 3.

Cone-Beam CT With Enhanced Needle Guidance and Augmented Fluoroscopy Overlay: Applications in Interventional Radiology.

Digital flat-panel detector cone-beam CT (CBCT), introduced in the early 2000s, was historically used in interventional radiology primarily for liver-directed therapies. However, contemporary advanced imaging applications, including enhanced needle guidance and augmented fluoroscopy overlay, have evolved substantially over the prior decade and now work synergistically with CBCT guidance to overcome limitations encountered with other imaging modalities. CBCT with advanced imaging applications has become increasingly used to facilitate a broad range of minimally invasive procedures, particularly relating to pain and musculoskeletal interventions.

Functionalized Silicon Particles for Enhanced Half- and Full-Cell Cycling of Si-Based Li-Ion Batteries.

Vinylene carbonate (VC) and polyethylene oxide (PEO) have been investigated as functional agents that mimic the solid electrolyte interphase (SEI) chemistry of silicon (Si). VC and PEO are known to contribute to the stability of Si-based lithium-ion batteries as an electrolyte additive and as a SEI component, respectively. In this work, covalent surface functionalization was achieved via a facile route, which involves ball-milling the Si particles with sacrificial VC and PEO.

Development and implementation of a novel peer mentoring program for undergraduate nursing students.

Objectives: Given the dynamic and high-stress environment of nursing education today, the need arose for the development and implementation of a novel peer mentoring program to support undergraduate nursing students. Peer mentoring refers to a network of support in which a more skilled or experienced person serves as a role model for a less skilled person for professional development and personal growth. Peer mentoring provides a support system that encourages self-confidence and increases self-worth for both the mentee and the mentor.

Physical activity programs for cardiovascular outcomes in community wheelchair users: A systematic review.

Purpose: Physical inactivity is one of the important factors leading to chronic diseases including cardiovascular disease (CVD) in individuals with disabilities. However, not many Physical Activity (PA) interventions are available for improving the efficacy of PA and cardiovascular outcomes among community wheelchair users. Therefore, this systematic review will appraise the existing PA interventions for the community dwelling wheelchair users; we especially examined features of the PA programs that showed the improvements in PA and the CVD outcomes compared to the interventions that did not show any improvements in these outcomes among these population.

Local Control of Cancers With Various Ablation Techniques.

Metastatic disease to the bone and soft tissue creates significant morbidity because of pain resulting in decreased functional status. Palliative chemotherapy and radiation therapy were historically the mainstays of pain reduction. Minimally invasive technologies such as image-guided ablation and cementoplasty have become common in interventional radiology.

A First Principles Approach to Subjective Experience.

Understanding the neural bases of subjective experience remains one of the great challenges of the natural sciences. Higher-order theories of consciousness are typically defended by assessments of neural activity in higher cortical regions during perception, often with disregard to the nature of the neural computations that these regions execute. We have sought to refocus the problem toward identification of those neural computations that are necessary for subjective experience with the goal of defining the sorts of neural architectures that can perform these operations.

Acute ischemic stroke or migraine with aura? Triage considerations.

Vertebroplasty, Kyphoplasty, and Implant-Based Mechanical Vertebral Augmentation.

Vertebral compression fractures are a global public health issue with a quantifiable negative impact on patient morbidity and mortality. The contemporary approach to the treatment of osteoporotic fragility fractures has moved beyond first-line nonsurgical management. An improved understanding of biomechanical forces, consequential morbidity and mortality, and the drive to reduce opioid use has resulted in multidisciplinary treatment algorithms and significant advances in augmentation techniques.

Connecting Evidence-Based Practice and Clinical Practice Guidelines With Bachelor of Science in Nursing Students.

Research has demonstrated the ability of evidence-based practice (EBP) to enhance quality and reliability of health care, improve health outcomes, and reduce cost and health disparities. Nursing curricula often lack best practices for teaching EBP, as well as actual EBP course content, objectives, and activities, to advance student understanding of EBP. The unfortunate results are nurse graduates who do not value or perceive that they can use EBP.

Probing the Reactivity of the Active Material of a Li-Ion Silicon Anode with Common Battery Solvents.

Calculations and modeling have shown that replacing the traditional graphite anode with silicon can greatly improve the energy density of lithium-ion batteries. However, the large volume change of silicon particles and high reactivity of lithiated silicon when in contact with the electrolyte lead to rapid capacity fading during charging/discharging processes. In this report, we use specific lithium silicides (LS) as model compounds to systematically study the reaction between lithiated Si and different electrolyte solvents, which provides a powerful platform to deconvolute and evaluate the degradation of various organic solvents in contact with the active lithiated Si-electrode surface after lithiation.

Neural Design Principles for Subjective Experience: Implications for Insects.

How subjective experience is realized in nervous systems remains one of the great challenges in the natural sciences. An answer to this question should resolve debate about which animals are capable of subjective experience. We contend that subjective experience of sensory stimuli is dependent on the brain's awareness of its internal neural processing of these stimuli.
