Convergent-beam attosecond x-ray crystallography.

Sub-ångström spatial resolution of electron density coupled with sub-femtosecond to few-femtosecond temporal resolution is required to directly observe the dynamics of the electronic structure of a molecule after photoinitiation or some other ultrafast perturbation, such as by soft X-rays. Meeting this challenge, pushing the field of quantum crystallography to attosecond timescales, would bring insights into how the electronic and nuclear degrees of freedom couple, enable the study of quantum coherences involved in molecular dynamics, and ultimately enable these dynamics to be controlled. Here, we propose to reach this realm by employing convergent-beam x-ray crystallography with high-power attosecond pulses from a hard-x-ray free-electron laser.

Surgical Site Infection After Sacral Neuromodulation: Impact of Postoperative Antibiotics.

Importance: There are limited data to guide practices to reduce surgical site infections following sacral neuromodulation; however, many surgeons prescribe prophylactic postoperative antibiotics after device implantation.

Objective: The aim of the study was to compare the proportion of patients with sacral neuromodulation device-associated surgical site infections after use of prophylactic postoperative antibiotics versus none.

Study Design: This was a multicenter retrospective cohort study of patients undergoing sacral neuromodulation device implantation at 11 institutions from January 2014 to December 2023, comparing outcomes in patients who did versus did not receive prophylactic postoperative antibiotic treatment.

Fast and efficient hard X-ray projection imaging below 10 nm resolution.

High-resolution X-ray imaging of noncrystalline objects is often achieved through the approach of scanning coherent diffractive imaging known as ptychography. The imaging resolution is usually limited by the scattering properties of the sample, where weak diffraction signals at the highest scattering angles compete with parasitic scattering. Here, we demonstrate that X-ray multilayer Laue lenses with a high numerical aperture (NA) can be used to create a strong reference beam that holographically boosts weak scattering from the sample over a large range of scattering angles, enabling high-resolution imaging that is tolerant of such background.

Development of MHz X-ray phase contrast imaging at the European XFEL.

We report on recent developments that enable megahertz hard X-ray phase contrast imaging (MHz XPCI) experiments at the Single Particles, Clusters, and Biomolecules and Serial Femtosecond Crystallography (SPB/SFX) instrument of the European XFEL facility (EuXFEL). We describe the technical implementation of the key components, including an MHz fast camera and a modular indirect X-ray microscope system based on fast scintillators coupled through a high-resolution optical microscope, which enable full-field X-ray microscopy with phase contrast of fast and irreversible phenomena. The image quality for MHz XPCI data showed significant improvement compared with a pilot demonstration of the technique using parallel beam illumination, which also allows access to up to 24 keV photon energies at the SPB/SFX instrument of the EuXFEL.

Considerations in Prescribing and De-Prescribing in Pediatric Functional Neurological Disorders.

Functional neurological disorder (FND) is common among children and adolescents, results in significant impairments in quality of life, and places a substantial burden on healthcare systems. Despite this, there is minimal literature to guide prescribing for this population. The purpose of this article is to provide common sense prescribing recommendations for providers who treat pediatric FND.

Social connection in long-term care homes: a qualitative study of barriers and facilitators.

Background: Social connection is a basic human need and is essential to quality of life. It is associated with better mental and physical health outcomes for long-term care (LTC) home residents and is a key aspect of quality of care and person-centred care. There are considerations for LTC homes that may present obstacles to and opportunities for social connection.

Development of crystal optics for X-ray multi-projection imaging for synchrotron and XFEL sources.

X-ray multi-projection imaging (XMPI) is an emerging experimental technique for the acquisition of rotation-free, time-resolved, volumetric information on stochastic processes. The technique is developed for high-brilliance light-source facilities, aiming to address known limitations of state-of-the-art imaging methods in the acquisition of 4D sample information, linked to their need for sample rotation. XMPI relies on a beam-splitting scheme, that illuminates a sample from multiple, angularly spaced viewpoints, and employs fast, indirect, X-ray imaging detectors for the collection of the data.

This is the protocol for a Campbell systematic review. This review's objectives are to find out (in relation to health and/or social care): (1) What is known about the outcomes and impact of completing (or not completing) a professional doctorate in health and/or social care on the individual professional? (2) What is known about the outcome and impact of completing (or not completing) a professional doctorate in health and/or social care on the employing organisation? (3) What is known about the outcome and impact of completing (or not completing) a professional doctorate in health and/or social care on the profession? (4) What is known about the outcome and impact of completing (or not completing) a professional doctorate in health and/or social care on service users and the wider society? (5) How do we use the findings from this review to inform educators, higher education institutions, professionals, investors in employing organisations and policymakers? (6) What further research will be needed to answer any knowledge gaps or recommendations? (7) Where possible, we will identify and report on any demographic data and discuss their relevance to the impact and outcomes from professional doctorates.

Assessing social connection for long-term care home residents: A scoping review of measure content.

Introduction: Social connection comprises distinct but interrelated aspects describing how individuals connect to each other. Various measures have assessed multiple aspects of social connection in long-term care (LTC) home populations, but they use inconsistent terminology, making it unclear what aspects are measured. This scoping review describes how social connection is assessed by measures that have been used in LTC home residents.

Characterization of Effects of mTOR Inhibitors on Aging in Caenorhabditis elegans.

Pharmacological inhibition of the mechanistic target of rapamycin (mTOR) signaling pathway with rapamycin can extend lifespan in several organisms. Although this includes the nematode Caenorhabditis elegans, effects in this species are relatively weak and sometimes difficult to reproduce. Here we test effects of drug dosage and timing of delivery to establish the upper limits of its capacity to extend life, and investigate drug effects on age-related pathology and causes of mortality.

Assessing social connection for long-term care home residents: Systematic review using COnsensus-based Standards for the selection of health Measurement INstruments guidelines.

Unlabelled: Social connection is important for long-term care (LTC) residents' quality of life and care. However, there is a lack of consensus on how to measure it and this limits ability to find what improves and impairs social connection in LTC homes. We therefore aimed to systematically review and evaluate the measurement properties of existing measures of social connection for LTC residents, to identify which, if any, measures can be recommended.

Allosensitisation in NHP results in cross-reactive anti-SLA antibodies not detected by a lymphocyte-based flow cytometry crossmatch.

Xenotransplantation is a potential option for individuals for whom an acceptable human allograft is unavailable. Individuals with broadly reactive HLA antibodies due to prior exposure to foreign HLA are potential candidates for a clinical xenotransplant trial. It remains controversial if allosensitisation results in the development of cross-reactive antibodies against SLA.

The present work examines the prevalence, presentation, and clinical associations of substance use disorders in U.

A fibroblast-dependent TGF-β1/sFRP2 noncanonical Wnt signaling axis promotes epithelial metaplasia in idiopathic pulmonary fibrosis.

Reciprocal interactions between alveolar fibroblasts and epithelial cells are crucial for lung homeostasis, injury repair, and fibrogenesis, but underlying mechanisms remain unclear. To investigate, we administered the fibroblast-selective TGF-β1 signaling inhibitor epigallocatechin gallate (EGCG) to interstitial lung disease (ILD) patients undergoing diagnostic lung biopsy and conducted single-cell RNA-Seq on spare tissue. Biopsies from untreated patients showed higher fibroblast TGF-β1 signaling compared with nondisease donor or end-stage ILD tissues.
