Two widely applied unloading therapies are a valgus unloader brace and a high tibial osteotomy (HTO). We aimed to compare the effects of a valgus unloader knee brace with an HTO on knee pain after 1 year in patients with symptomatic medial knee OA.

Radiotherapy and surgery: can this combination be further optimized for patients with metastatic spine disease?

This narrative review provides a comprehensive overview of the current status, recent advancements, and future directions in the management of metastatic spine disease using both radiotherapy and surgery. Emphasis has been put on the integrated use of radiotherapy and surgery, incorporating recent developments such as separation surgery, active dose sparing of the surgical field, and the implementation of carbon fiber-reinforced polymer implants. Future studies should explore the effects of minimizing the time between radiotherapy and surgery and investigate the potential of vertebral re-ossification after radiotherapy to obviate the need for stabilization surgery.

Integrated artificial neurons from metal halide perovskites.

Hardware neural networks could perform certain computational tasks orders of magnitude more energy-efficiently than conventional computers. Artificial neurons are a key component of these networks and are currently implemented with electronic circuits based on capacitors and transistors. However, artificial neurons based on memristive devices are a promising alternative, owing to their potentially smaller size and inherent stochasticity.

Approaches to Incorporation of Preferences into Health Economic Models of Genomic Medicine: A Critical Interpretive Synthesis and Conceptual Framework.

Introduction: Genomic medicine has features that make it preference sensitive and amenable to model-based health economic evaluation. Preferences of patients, caregivers, and clinicians related to the uptake and delivery of genomic medicine technologies and services that are not captured in health state utility weights can affect the intervention's cost-effectiveness and budget impact. However, there is currently no established or agreed-on approach for integrating preference information into economic evaluations.

Optimized breath analysis: customized analytical methods and enhanced workflow for broader detection of VOCs.

Introduction: Breath Volatile organic compounds (VOCs) are promising biomarkers for clinical purposes due to their unique properties. Translation of VOC biomarkers into the clinic depends on identification and validation: a challenge requiring collaboration, well-established protocols, and cross-comparison of data. Previously, we developed a breath collection and analysis method, resulting in 148 breath-borne VOCs identified.

Road coverage as demand metric for ambulance allocation.

Ambulances must be strategically placed to ensure timely patient care and save lives. The allocation problem considered in the current paper optimally distributes a fixed number of ambulances over predetermined bases with limited capacity. Ambulance allocation problems are usually solved through historical demand.

Relationship of maternal ophthalmic artery Doppler with uterine artery Doppler, hemodynamic indices and gestational age: prospective MATERA study.

Objectives: To examine the relationship of ophthalmic artery (OA) Doppler indices with uterine artery (UtA) Doppler indices, selected maternal hemodynamic parameters and gestational age, and to evaluate the intraobserver reproducibility of OA Doppler indices.

Methods: This was a prospective cohort study of women recruited between 11 + 0 and 23 + 6 weeks' gestation using a stratified and random sampling approach to ensure adequate distribution across the gestational-age range. OA pulsatility index (PI), first peak systolic velocity (PSV1), second peak systolic velocity (PSV2) and peak systolic velocity ratio (PSV ratio), calculated as PSV2/PSV1, were measured twice in each eye by the same observer.

Unmet needs in the management of patients with bilateral synchronous renal masses: the rationale for clinical decision-making.

Background: Bilateral synchronous renal masses (BSRMs) are a rare finding, and the optimal treatment strategy remains undetermined. This study depicts the management of BSRM at eight European high-volume centers.

Methods: This is a retrospective analysis of prospective institutional databases collecting all patients presenting with clinical T1-2 N0 M0 BSRMs between 1993 and 2020 at 8 tertiary referral high-volume centers for renal cancer treatment in Europe.

Androgens differentially modulate glucocorticoid effects on adipose tissue and lean mass.

Glucocorticoids and androgens affect each other in several ways. In metabolic organs such as adipose tissue and the liver, androgens enhance glucocorticoid-induced insulin resistance and promote fat accumulation in male mice. However, the direct contribution of the androgen receptor (AR) to these effects is unknown.

Highly Efficient and Stable CsPbI Perovskite Quantum Dots Light-Emitting Diodes Through Synergistic Effect of Halide-Rich Modulation and Lattice Repair.

Currently, CsPbI quantum dots (QDs) based light-emitting diodes (LEDs) are not well suited for achieving high efficiency and operational stability due to the binary-precursor method and purification process, which often results in the nonstoichiometric ratio of Cs/Pb/I. This imbalance leads to amounts of iodine vacancies, inducing severe non-radiative recombination processes and phase transitions of QDs. Herein, red-emitting CsPbI QDs are reported with excellent optoelectronic properties and stability based on the synergistic effects of halide-rich modulation passivation and lattice repair.

The impact of radiofrequency thermocoagulation on brain connectivity in drug-resistant epilepsy: Insights from stereo-electroencephalography and cortico-cortical evoked potentials.

Objective: To investigate whether local lesions created by stereo-electroencephalography (SEEG)-guided radiofrequency thermocoagulation (RFTC) affect distant brain connectivity and excitability in patients with focal, drug-resistant epilepsy (DRE).

Methods: Ten patients with focal DRE underwent SEEG implantation and subsequently 1 Hz bipolar repetitive electrical stimulation (RES) for 30 s before and after RFTC. Root mean square (RMS) of cortico-cortical evoked potentials (CCEPs) was calculated for 15 ms to 300 ms post-stimulation with baseline correction.

Influence of solution stoichiometry on the thermodynamic stability of prenucleation FeS clusters.

The significance of iron sulphide (FeS) formation extends to "origin of life" theories, industrial applications, and unwanted scale formation. However, the initial stages of FeS nucleation, particularly the impact of solution composition, remain unclear. Often, the iron and sulphide components' stoichiometry in solution differs from that in formed particles.

How Do Nurses Decide on Missed Nursing Care? A Grounded Theory Study of Grassroots Arrangement of Nursing Care.

Aims: To explore the complete decision-making process and action logic of nurses making autonomous decisions that result in missed nursing care.

Background: The complex characteristics of patients in Intensive Care Units place higher demands on the allocation of nursing resources, as well as on the professional skills, resilience and ethics of nursing staff. Preventing missed nursing care is particularly crucial in Intensive Care Units.

Plant species, inundation, and sediment grain size control the development of sediment stability in tidal marshes.

Tidal marshes can contribute to nature-based shoreline protection by reducing the wave load onto the shore and reducing the erosion of the sediment bed. To implement such nature-based shoreline erosion protection requires the ability to quickly restore or create highly stable and erosion-resistant tidal marshes at places where they currently do not yet occur. Therefore, we aim to identify the drivers controlling the rate by which sediment stability builds up in young pioneer marshes.

"Showing the Best Version of Yourself": The Importance of Dynamic Assessment for Trainees Undergoing Workplace-Based Assessments in Postgraduate Training.

Workplace-based assessments (WPBAs) in postgraduate training may not always provide an accurate representation of a trainee's capability to perform a given task, or a true measure of a trainee's overall competence in clinical practice settings. This article describes how trainers can use a theory-driven and evidence-based intervention called dynamic assessment for providing an individual with the best opportunity to demonstrate a more accurate representation of their performance, and ultimately present the best version of themselves when undergoing an observed WPBA, such as a Direct Observation of Procedural Skills (DOPS) or Mini Consultation Evaluation Exercise (MiniCEX). Dynamic assessment simultaneously combines educational support with assessment as the trainee undergoes the WPBA by using focussed questions as prompts to facilitate an individual trainee's essential coordination of their motivational and thinking processes since this is often challenged during assessments.
