Contextual cues can be used to predict the likelihood of and reduce interference from salient distractors.

Atten Percept Psychophys

Department of Psychology, The Ohio State University, 1835 Neil Ave, Columbus, OH, 43210, USA.

Our attention can sometimes be disrupted by salient but irrelevant objects in the environment. This distractor interference can be reduced when distractors appear frequently, allowing us to anticipate their presence. However, it remains unknown whether distractor frequency can be learned implicitly across distinct contexts.

Deaths of parents and grandparent caregivers threaten child well-being owing to losses of care, financial support, safety and family stability, but are relatively unrecognized as a public health crisis. Here we used cause-specific vital statistics death registrations in a modeling approach to estimate the full magnitude of orphanhood incidence and prevalence among US children aged 0-17 years between 2000 and 2021 by cause, child age, race and ethnicity, sex of deceased parent and state, and also accounted for grandparent caregiver loss using population survey data. In 2021, we estimate that 2.

Department of Oral Medicine, Guy´s and St Thomas´ NHS Foundation Trust, London, UK; Faculty of Dentistry, Oral and Craniofacial Sciences, King´s College London, London, UK.

Artificial intelligence (AI) is a rapidly evolving area, having had a transformative effect within some areas of medicine and dentistry. In dentistry, AI systems are contributing to clinical decision-making, diagnostics and treatment planning. Ongoing advances in AI technology will lead to further expansion of its existing applications and more widespread use within the field of dentistry.

SNOMED-CT and learning health systems for NHS dentistry - a dream needing to become reality.

Br Dent J

January 2025

Professor of Oral and Maxillofacial Surgery, Faculty of Medicine and Dentistry, Queen Mary University of London, London, UK; Bloomsbury Trust, London, UK.

There has been discussion and confusion about SNOMED-CT (systematised nomenclature of medicine clinical terminology), learning health systems (LHSs) and their relevance in dentistry. This article aims to provide an overview of SNOMED-CT, LHSs and the all-too-often omitted patient and service benefits from their use. LHSs are delivering impactful benefits to patients and services globally in medicine.

Gene expression quantitative trait loci are widely used to infer relationships between genes and central nervous system (CNS) phenotypes; however, the effect of brain disease on these inferences is unclear. Using 2,348,438 single-nuclei profiles from 391 disease-case and control brains, we report 13,939 genes whose expression correlated with genetic variation, of which 16.7-40.

The COVID-19 pandemic exposed a global deficiency of systematic, data-driven guidance to identify high-risk individuals. Here, we illustrate the utility of routinely recorded medical history to predict the risk for 1741 diseases across clinical specialties and support the rapid response to emerging health threats such as COVID-19. We developed a neural network to learn from health records of 502,489 UK Biobank participants.

Thermosensory signals may contribute to the sense of body ownership, but their role remains highly debated. We test this assumption within the framework of pathological body ownership, hypothesising that skin temperature and thermoception differ between right-hemisphere stroke patients with and without Disturbed Sensation of Ownership (DSO) for the contralesional plegic upper limb. Patients with DSO exhibit lower basal hand temperatures bilaterally and impaired perception of cold and warm stimuli.

Background: Fabry disease is an X-linked lysosomal storage disorder due to a deficiency of α-galactosidase A (α-gal A) activity. Our goal was to correct the enzyme deficiency in Fabry patients by transferring the cDNA for α-gal A into their CD34+ hematopoietic stem/progenitor cells (HSPCs). Overexpression of α-gal A leads to secretion of the hydrolase; which can be taken up and used by uncorrected bystander cells.

Physiological basis of non-invasive ventilation in the newborn.

Semin Perinatol

December 2024

Department of Women and Children's Health, School of Life Course Sciences, Faculty of Life Sciences and Medicine, King's College London, London, United Kingdom; Neonatal Intensive Care Unit, University of Patras, Patras, Greece. Electronic address:

Non-invasive ventilation (NIV) is a form of respiratory support provided primarily to preterm born infants in an effort to avoid any endotracheal intubation or as a weaning step following invasive ventilation. In the context of the respiratory distress syndrome of the newborn, NIV could target and partially reverse specific pathophysiological phenomena, by improving alveolar recruitment and establishing adequate functional residual capacity. It can also assist in minimizing lung injury by avoiding excessive pressure delivery, which can be harmful for the developing lung.

The α-synuclein seed amplification assay: Interpreting a test of Parkinson's pathology.

Parkinsonism Relat Disord

December 2024

Department of Translational Neuroscience and the Muhammad Ali Parkinson Center, Barrow Neurological Institute, Phoenix, AZ, USA.

The α-synuclein seed amplification assay (αSyn-SAA) sensitively detects Lewy pathology, the amyloid state of α-synuclein, in the cerebrospinal fluid (CSF) of patients with Parkinson's disease (PD). The αSyn-SAA harnesses the physics of seeding, whereby a superconcentrated solution of recombinant α-synuclein lowers the thermodynamic threshold (nucleation barrier) for aggregated α-synuclein to act as a nucleation catalyst ("seed") to trigger the precipitation (nucleation) of monomeric α-synuclein into pathology. This laboratory setup increases the signal for identifying a catalyst if one is present in the tissue examined.

The influence of phosphoinositide lipids in the molecular biology of membrane proteins: recent insights from simulations.

J Mol Biol

January 2025

Institute of Biological Chemistry, Academia Sinica, Taipei 115 Taiwan; Department of Chemistry, University of Oxford, South Parks Road, Oxford OX1 3QZ UK.

The phosphoinositide family of membrane lipids play diverse and critical roles in eukaryotic molecular biology. Much of this biological activity derives from interactions of phosphoinositide lipids with integral and peripheral membrane proteins, leading to modulation of protein structure, function, and cellular distribution. Since the discovery of phosphoinositides in the 1940s, combined molecular biology, biophysical, and structural approaches have made enormous progress in untangling this vast and diverse cellular network of interactions.

The genetic architecture of differentiating behavioral and emotional problems in early life.

PsychGen Center for Genetic Epidemiology and Mental Health, Norwegian Institute of Public Health, Oslo, Norway; Psychiatric Genetic Epidemiology group, Research Department, Lovisenberg Diaconal Hospital, Oslo, Norway; MRC Integrative Epidemiology Unit, Bristol Medical School, University of Bristol, Bristol, UK. Electronic address:

Background: Early in life, behavioral and cognitive traits associated with risk for developing a psychiatric condition are broad and undifferentiated. As children develop, these traits differentiate into characteristic clusters of symptoms and behaviors that ultimately form the basis of diagnostic categories. Understanding this differentiation process - in the context of genetic risk for psychiatric conditions, which is highly generalized - can improve early detection and intervention.

Amyotrophic lateral sclerosis (ALS) presents a substantial challenge due to its complex nature, limited effective treatment options, and modest benefits from current therapies in slowing disease progression. This study explores the potential of intranasal (IN) delivery to enhance the CNS delivery of riluzole (RLZ), a standard ALS treatment which is subject to blood-brain barrier efflux mechanisms. Additionally, the impact of elacridar (ELC), an efflux pump inhibitor, on IN RLZ CNS bioavailability was examined.
