High-level cognition is supported by information-rich but compressible brain activity patterns.

To efficiently yet reliably represent and process information, our brains need to produce information-rich signals that differentiate between moments or cognitive states, while also being robust to noise or corruption. For many, though not all, natural systems, these two properties are often inversely related: More information-rich signals are less robust, and vice versa. Here, we examined how these properties change with ongoing cognitive demands.

SOMAScience: A Novel Platform for Multidimensional, Longitudinal Pain Assessment.

Chronic pain is one of the most significant health issues in the United States, affecting more than 20% of the population. Despite its contribution to the increasing health crisis, reliable predictors of disease development, progression, or treatment outcomes are lacking. Self-report remains the most effective way to assess pain, but measures are often acquired in sparse settings over short time windows, limiting their predictive ability.

Heterogeneous Fenton's-like catalyst potentiation of hydrogen peroxide disinfection: an investigation into mechanisms of action.

Aims: This study aimed to establish the mechanisms of action (MOA) of a novel surface-functionalized polyacrylonitrile (PAN) catalyst, which was previously shown to have potent antimicrobial activity in conjunction with hydrogen peroxide (H2O2).

Methods And Results: Bactericidal activity was determined using a disinfectant suspension test. The MOA was investigated by measuring the loss of 260 nm absorbing material, membrane potential, permeability assays, analysis of intra- and extracellular ATP and pH, and tolerance to sodium chloride and bile salts.

A multidisciplinary simulation programme to improve advance care planning skills and engagement across primary and secondary care.

Background: In the context of an ageing population, many healthcare professionals have limited experience and confidence in having necessary advance care planning (ACP) conversations.

Methods: We conducted nine half-day simulation sessions, using professional actors. One-hundred and thirty-two participants attended from multidisciplinary backgrounds across primary and secondary care.

Preserved motor memory in Parkinson's disease.

Patients with Parkinson's disease, who lose the dopaminergic projections to the striatum, are impaired in certain aspects of motor learning. Recent evidence suggests that, in addition to its role in motor performance, the striatum plays a key role in the memory of motor learning. Whether Parkinson's patients have impaired motor memory and whether motor memory is modulated by dopamine at the time of initial learning is unknown.

Health care worker knowledge and attitudes towards uniform laundering during the COVID-19 pandemic.

Background: The COVID-19 pandemic raised concerns towards domestic laundering of healthcare worker (HCW) uniforms; this is common practice in countries such as the United Kingdom (UK) and United States. Previous research suggested 4-32% of nurses did not adhere to laundry policies, which could be an infection control risk. This study aimed to investigate the knowledge and attitudes of UK healthcare workers towards domestic laundering of uniforms during the COVID-19 pandemic.

Porous surfaces: stability and recovery of coronaviruses.

The role of indirect contact in the transmission of SARS-CoV-2 is not clear. SARS-CoV-2 persists on dry surfaces for hours to days; published studies have largely focused on hard surfaces with less research being conducted on different porous surfaces, such as textiles. Understanding the potential risks of indirect transmission of COVID-19 is useful for settings where there is close contact with textiles, including healthcare, manufacturing and retail environments.

Antiviral plant-derived natural products to combat RNA viruses: Targets throughout the viral life cycle.

There is a need for new effective antivirals, particularly in response to the development of antiviral drug resistance and emerging RNA viruses such as SARS-CoV-2. Plants are a significant source of structurally diverse bioactive compounds for drug discovery suggesting that plant-derived natural products could be developed as antiviral agents. This article reviews the antiviral activity of plant-derived natural products against RNA viruses, with a focus on compounds targeting specific stages of the viral life cycle.

Distributed Subnetworks of Depression Defined by Direct Intracranial Neurophysiology.

Major depressive disorder is a common and disabling disorder with high rates of treatment resistance. Evidence suggests it is characterized by distributed network dysfunction that may be variable across patients, challenging the identification of quantitative biological substrates. We carried out this study to determine whether application of a novel computational approach to a large sample of high spatiotemporal resolution direct neural recordings in humans could unlock the functional organization and coordinated activity patterns of depression networks.

High-level cognition during story listening is reflected in high-order dynamic correlations in neural activity patterns.

Our thoughts arise from coordinated patterns of interactions between brain structures that change with our ongoing experiences. High-order dynamic correlations in neural activity patterns reflect different subgraphs of the brain's functional connectome that display homologous lower-level dynamic correlations. Here we test the hypothesis that high-level cognition is reflected in high-order dynamic correlations in brain activity patterns.

Investigation of the stability and risks of fomite transmission of human coronavirus OC43 on leather.

Limited research exists on the potential for leather to act as a fomite of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) or endemic coronaviruses including human coronavirus (HCoV) OC43; this is important for settings such as the shoe manufacturing industry. Antiviral coating of leather hides could limit such risks. This study aimed to investigate the stability and transfer of HCoVOC43 on different leathers, as a surrogate for SARS-CoV-2, and assess the antiviral efficacy of a silver-based leather coating.

The Stability of Model Human Coronaviruses on Textiles in the Environment and during Health Care Laundering.

Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) persists on stainless steel and plastic for up to 7 days, suggesting that coronavirus disease 2019 (COVID-19) could be spread by fomite transmission. There is limited research on the stability of SARS-CoV-2 on textiles, with the risk of textiles acting as fomites not being well understood. To date, there does not appear to be any published research on the stability of coronaviruses during laundering, which is required to determine the efficacy of current laundering policies in the decontamination of health care textiles.

The role of textiles as fomites in the healthcare environment: a review of the infection control risk.

Background: Infectious diseases are a significant threat in both healthcare and community settings. Healthcare associated infections (HCAIs) in particular are a leading cause of complications during hospitalisation. Contamination of the healthcare environment is recognised as a source of infectious disease yet the significance of porous surfaces including healthcare textiles as fomites is not well understood.

A Gaussian Process Model of Human Electrocorticographic Data.

We present a model-based method for inferring full-brain neural activity at millimeter-scale spatial resolutions and millisecond-scale temporal resolutions using standard human intracranial recordings. Our approach makes the simplifying assumptions that different people's brains exhibit similar correlational structure, and that activity and correlation patterns vary smoothly over space. One can then ask, for an arbitrary individual's brain: given recordings from a limited set of locations in that individual's brain, along with the observed spatial correlations learned from other people's recordings, how much can be inferred about ongoing activity at other locations throughout that individual's brain? We show that our approach generalizes across people and tasks, thereby providing a person- and task-general means of inferring high spatiotemporal resolution full-brain neural dynamics from standard low-density intracranial recordings.

Advance care planning: the who, what, when, where and why.

Advance care planning is an opportunity for patients to express their priorities for future care. NHS England has outlined a commitment to end-of-life care, advocating a shift towards more patient-centred care. The NHS is encouraging the workforce to engage patients in conversations about what is important to them, shifting the focus from 'what is wrong with you' to 'what matters to you'.

From formulation to in vivo model: A comprehensive study of a synergistic relationship between vancomycin, carvacrol, and cuminaldehyde against Enterococcus faecium.

Vancomycin-resistant Enterococcus faecium (VRE) has become endemic in healthcare settings, reducing treatment options for enterococcal infections. New antimicrobials for VRE infections are a high priority, but the development of novel antibiotics is time-consuming and expensive. Essential oils (EOs) synergistically enhance the activity of some existing antibiotics, suggesting that EO-antibiotic combinations could resensitise resistant bacteria and maintain the antibiotic repertoire.

Advance care planning: what do patients want?

Introduction: Advance care planning is the process by which patients can make decisions about their future health care should they lose capacity. Such conversations are shown to improve quality of life and reduce institutionalization. This article explores the preferences and wishes of patients in terms of advance care planning.

Characterisation and screening of antimicrobial essential oil components against clinically important antibiotic-resistant bacteria using thin layer chromatography-direct bioautography hyphenated with GC-MS, LC-MS and NMR.

Introduction: The antimicrobial activity of many essential oils (EOs) is well established, indicating that EOs may be a source of compounds for antimicrobial drug development. Thin layer chromatography-direct bioautography (TLC-DB) can quickly identify antimicrobial components in complex mixtures and can be applied to the screening of EOs for lead compounds.

Objectives: This study aimed to identify antimicrobial components of oregano, rosewood and cumin EOs against antibiotic-sensitive and -resistant bacteria using TLC-DB and a multi-faceted approach of GC-MS, LC-MS and NMR techniques to characterise bioactive compounds.

Synchronous application of antibiotics and essential oils: dual mechanisms of action as a potential solution to antibiotic resistance.

Antibiotic resistance has increased dramatically in recent years, yet the antibiotic pipeline has stalled. New therapies are therefore needed to continue treating antibiotic resistant infections. One potential strategy currently being explored is the use of non-antibiotic compounds to potentiate the activity of currently employed antibiotics.

Structure-activity modelling of essential oils, their components, and key molecular parameters and descriptors.

Many essential oil components are known to possess broad spectrum antimicrobial activity, including against antibiotic resistant bacteria. These compounds may be a useful source of new and novel antimicrobials. However, there is limited research on the structure-activity relationship (SAR) of essential oil compounds, which is important for target identification and lead optimization.

Delirium, Frailty, and Mortality: Interactions in a Prospective Study of Hospitalized Older People.

Background: It is unknown whether the association between delirium and mortality is consistent for individuals across the whole range of health states. A bimodal relationship has been proposed, where delirium is particularly adverse for those with underlying frailty, but may have a smaller effect (perhaps even protective) if it is an early indicator of acute illness in fitter people. We investigated the impact of delirium on mortality in a cohort simultaneously evaluated for frailty.

A Multifactorial Comparison of Ternary Combinations of Essential Oils in Topical Preparations to Current Antibiotic Prescription Therapies for the Control of Acne Vulgaris-Associated Bacteria.

Acne vulgaris, a chronic condition associated with overgrowth of Propionibacterium acnes and Staphylococcus epidermidis, is commonly treated with antibiotics. However, the emergence of antibiotic resistance has resulted in a need for alternative therapies. The aim of this study is to develop a topical preparation incorporating essential oils (EOs) for use against acne-associated bacteria and assess its efficacy against prescription therapies Dalacin T and Stiemycin.

Parent-child relationships and the psychological well-being of 18-year-old adolescents conceived by in vitro fertilisation.

This article presents the findings of the first study to have followed up children conceived by in vitro fertilisation (IVF) to late adolescence. As close as possible to their eighteenth birthday, standardised interviews and questionnaires were administered to 26 adolescents conceived by IVF and comparison groups of 27 adolescents adopted in infancy and 56 adolescents conceived naturally by previously infertile parents. IVF adolescents were found to have good relationships with their parents that did not differ from those of adopted and natural conception adolescents.
