Introduction: Ultrasound-guided regional anaesthesia enhances pain control, patient outcomes and lowers healthcare costs. However, teaching this skill effectively presents challenges with current training methods. Simulation-based medical education offers advantages over traditional methods.

Birth weight and head circumference for 22-29 weeks gestation neonates from an international cohort.

Objective: Size at birth is a key indicator of in utero growth. Our objective was to generate sex-specific percentiles for birth weight and head circumference in neonates born between 22 and 29 weeks gestation from pregnancies without hypertension or diabetes and assess differences between vaginal and caesarean births and between singletons and twins.

Methods: We used data from 12 countries participating in the International Network for Evaluating Outcomes in Neonates database from 2007 to 2021.

Tract-specific white matter hyperintensities and neuropsychiatric syndromes: a multicentre memory clinic study.

Background: White matter hyperintensities (WMH) have been implicated in the pathogenesis of neuropsychiatric symptoms of dementia but the functional significance of WMH in specific white matter (WM) tracts is unclear. We investigate whether WMH burden within major WM fibre classes and individual WM tracts are differentially associated with different neuropsychiatric syndromes in a large multicentre study.

Method: Neuroimaging and neuropsychiatric data of seven memory clinic cohorts through the Meta VCI Map consortium were harmonised.

Magnetic resonance imaging based anatomy of the conus medullaris: variations of location and morphology.

Background: In adults, the conus medullaris( CM) tip usually terminates at the mid aspect of the L1 vertebra. However, variations exist. Beside the location, differences in the CM's shape are believed to be closely related to neurological conditions.

Application of Automated face coding (AFC) in older adults: a pilot study.

By examining the seven fundamental emotions, the study sought to understand how these emotions manifest and their potential implications for dental care in this population.

Methods: Fifty care-dependent older adults' (mean-age: 78.

Accuracy of digital and conventional implant impressions in edentulous jaws: a clinical comparative study.

Objectives: This clinical study aimed to evaluate the accuracy of digital and conventional implant impressions in a fully edentulous maxilla and mandible.

Methods: A 53-year-old edentulous patient with four maxillary and two mandibular implants was selected. Ten intraoral scans (IOS) and a conventional impression per jaw were taken.

High-resolution microCT analysis of sclerotic subchondral bone beneath bone-on-bone wear grooves in severe osteoarthritis.

Osteoarthritis (OA) is associated with sclerosis, a thickening of the subchondral bone plate, yet little is known about bone adaptations around full-thickness cartilage defects in severe knee OA, particularly beneath bone-on-bone wear grooves. This high-resolution micro-computed tomography (microCT) study aimed to quantify subchondral bone microstructure relative to cartilage defect location, distance from the joint space, and groove depth. Ten tibial plateaus with full-thickness cartilage defects were microCT-scanned to determine defect location and size.

Impact of coronary artery tortuosity on outcomes following stenting with newer-generation drug-eluting stents. An analysis of the randomized BIOFLOW trials.

Introduction And Objectives: Patients undergoing percutaneous coronary intervention in vessels with moderate-to-severe tortuosity are at higher risk of adverse outcomes, but data are scarce in the era of newer-generation stents. We compared outcomes following percutaneous coronary intervention in vessels with moderate-to-severe tortuosity using a bioresorbable-polymer sirolimus-eluting stent (BP-SES) vs a durable-polymer everolimus-eluting stent.

Methods: A total of 2350 patients from the BIOFLOW II, IV, and V randomized trials were stratified into 2 groups based on target-vessel tortuosity: none-to-mild and moderate-to-severe.

Evaluation of self-collected dried blood spots for detection of SARS-CoV-2 nucleocapsid antibodies shows low sensitivity.

Background And Aims: Dried blood spots (DBS) have been proposed as a cost-effective surveillance method for population-wide screening of SARS-CoV-2 immunity but sensitivity of DBS based on self-collected DBS samples is unknown. To evaluate the success of vaccination strategies, it is necessary to differentiate vaccination from natural infection. Therefore, a test for antibodies against the viral nucleocapsid protein (anti-N) is desirable.

From microalgae to gastropods: Understanding the kinetics and toxicity of silver nanoparticles in freshwater aquatic environment.

Silver nanoparticles (AgNPs) are increasingly used in various consumer products and industrial applications, raising concerns about their environmental impact on aquatic ecosystems. This study investigated the physicochemical stability, trophic transfer, and toxic effects of citrate-coated AgNPs in a freshwater food chain including the diatom Cyclotella meneghiniana and the gastropod Lymnaea stagnalis. AgNPs remained stable in the exposure medium, with a minimal dissolution (<0.

Optimum diagnostic pathway and pathologic confirmation rate of early stage lung cancer: Results from the VIOLET randomised controlled trial.

Background: Pathologic confirmation of lung cancer influences treatment selection for suspected early-stage lung cancer. High pre-treatment tissue confirmation rates are recommended. We sought to define management and outcomes of patients undergoing surgery for primary lung cancer in a UK multi-centre clinical trial.

Assessing the Risk for Falls in Older Adults After Initiating Gabapentin Versus Duloxetine.

Background: The evidence informing the harms of gabapentin use are at risk of bias from comparing users with nonusers.

Objective: To describe the risk for fall-related outcomes in older adults starting treatment with gabapentin versus duloxetine.

Design: New user, active comparator study using a target trial emulation framework.

Plasma pTau181 and amyloid markers predict conversion to dementia in idiopathic REM sleep behaviour disorder.

Blood-based biomarkers for Alzheimer's disease (AD) pathology have been intensively investigated as markers for AD-related neurodegeneration. Comorbid AD pathology is common in dementia with Lewy bodies (DLB). Accordingly, we hypothesized that plasma biomarkers associated with AD pathology might be useful to predict DLB in a cohort of idiopathic/isolated REM sleep behavior disorder (iRBD), an incipient synucleinopathy.

Longitudinal changes of macular neurodegenerative and vascular abnormalities on OCTA in sickle cell disease.

Purpose: To evaluate the presence and progression of maculopathy in patients with sickle cell disease (SCD) using Optical Coherence Tomography (OCT) and OCT-Angiography (OCTA), and to identify clinical/laboratory risk factors for progression during follow-up.

Methods: Complete ophthalmic examination, including fundoscopy and macular SD-OCT/OCTA scans, was performed in consecutive SCD-patients (HbSS/HbSβ0/HbSβ+/HbSC genotype) during baseline and follow-up visits. SCR stage was based on fundoscopy instead of the Goldberg classification, since fluorescein angiography was not routinely used.

Intraocular Inflammation (IOI) Associated with Faricimab Therapy: One-year Real World Outcomes.

Purpose: To report one-year real-world evidence on intraocular inflammation (IOI) adverse events (AEs) in patients undergoing faricimab therapy in a tertiary care hospital.

Methods: A retrospective review of electronic medical records was conducted for patients receiving faricimab treatment for neovascular age-related macular degeneration (nAMD) and diabetic macular edema (DME) at Moorfields Eye Hospital between September 1st, 2022, and August 31st, 2023. The primary outcome was the incidence of IOI (excluding endophthalmitis).

A Core Outcome Set for Adult General ICU Patients.

Objectives: Randomized clinical trials informing clinical practice (e.g., like large, pragmatic, and late-phase trials) should ideally mostly use harmonized outcomes that are important to patients, family members, clinicians, and researchers.

Completion of lunar magma ocean solidification at 4.43 Ga.

Crystallization of the lunar magma ocean yielded a chemically unique liquid residuum named KREEP. This component is expressed as a large patch on the near side of the Moon and a possible smaller patch in the northwest portion of the Moon's South Pole-Aitken basin on the far side. Thermal models estimate that the crystallization of the lunar magma ocean (LMO) could have spanned from 10 and 200 My, while studies of radioactive decay systems have yielded inconsistent ages for the completion of LMO crystallization covering over 160 My.

Pan-European atmospheric lead pollution, enhanced blood lead levels, and cognitive decline from Roman-era mining and smelting.

Ancient texts and archaeological evidence indicate substantial lead exposure during antiquity that potentially impacted human health. Although lead exposure routes were many and included the use of glazed tablewares, paints, cosmetics, and even intentional ingestion, the most significant for the nonelite, rural majority of the population may have been through background air pollution from mining and smelting of silver and lead ores that underpinned the Roman economy. Here, we determined potential health effects of this air pollution using Arctic ice core measurements of Roman-era lead pollution, atmospheric modeling, and modern epidemiology-based relationships between air concentrations, blood lead levels (BLLs), and cognitive decline.

Proton Accumulation Modulated Surface Potential in Proton Conducting Ceramics Revealed by Near-Ambient Pressure X-ray Photoelectron Spectroscopy.

Proton conducting electrochemical cells (PCECs) are efficient and clean intermediate-temperature energy conversion devices. The proton concentration across the PCECs is often nonuniform, and characterizing the distribution of proton concentration can help to locate the position of rate-limiting reactions. However, the determination of the local proton concentration under operating conditions remains challenging.

Modelling the health labour market outlook in Kenya: Supply, needs and investment requirements for health workers, 2021-2035.

Kenya is committed to achieving Universal Health Coverage (UHC) within its devolved health system in which significant investments have been made in health infrastructure, workforce development, and service delivery. Despite these efforts, the country faces considerable health workforce challenges. To address these, the Ministry of Health undertook a comprehensive Health Labour Market Analysis (HLMA) in 2022 to generate evidence supporting the development of responsive health workforce policies.

Role and modulation of various spinal pathways for human upper limb control in different gravity conditions.

Humans can perform movements in various physical environments and positions (corresponding to different experienced gravity), requiring the interaction of the musculoskeletal system, the neural system and the external environment. The neural system is itself comprised of several interactive components, from the brain mainly conducting motor planning, to the spinal cord (SC) implementing its own motor control centres through sensory reflexes. Nevertheless, it remains unclear whether similar movements in various environmental dynamics necessitate adapting modulation at the brain level, correcting modulation at the spinal level, or both.

Fragment-to-Lead Medicinal Chemistry Publications in 2023.

This Perspective summarizes successful fragment-to-lead (F2L) studies that were published in 2023 and is the ninth installment in an annual series. A tabulated summary of the relevant articles published in 2023 is provided (17 entries from 16 articles), and a comparison of the target classes, screening methods, and overall fragment or lead property trends for 2023 examples and for the combined entries over the years 2015-2023 is discussed. In addition, we identify several trends and innovations in the 2023 literature that promise to further increase the success of fragment-based drug discovery (FBDD), particularly in the areas of NMR and virtual screening, fragment library design, and fragment linking.
