Unraveling the Atomistic Mechanism of Electrostatic Lateral Association of Peptide β-Sheet Structures and Its Role in Nanofiber Growth and Hydrogelation.

Guiding molecular assembly of peptides into rationally engineered nanostructures remains a major hurdle against the development of functional peptide-based nanomaterials. Various non-covalent interactions come into play to drive the formation and stabilization of these assemblies, of which electrostatic interactions are key. Here, the atomistic mechanisms by which electrostatic interactions contribute toward controlling self-assembly and lateral association of ultrashort β-sheet forming peptides are deciphered.

A clinical trial evaluation of handwashing products and educational resources to improve hand hygiene in paediatric patients and school children.

Introduction: It is widely acknowledged that good hand hygiene (HH) is an important non-pharmaceutical method for reducing the transmission of infectious diseases. Children are at high risk of infection due to their immature immune systems. Hospital transmitted infections are a cause for concern worldwide, with poor HH suggested to be responsible for up to 20% of cases.

The longitudinal effect of disseminating handwashing public health education to children in India via co-created, culturally relevant resources.

Infectious diseases are a leading cause of death for children from low- and middle-income countries (LMICs), often due to inadequate hand-hygiene. This study evaluates culturally relevant educational resources as a vehicle to disseminate the importance of handwashing amongst children in India. Employing a participatory action research (PAR) model and mixed methods, this follow-up longitudinal study evaluates a set of innovate educational handwashing resources and workshops specifically co-created for use in the State of Gujarat, and how they aid teachers in the teaching of hand-hygiene over a 3 year period.

Disturbed sleep is associated with reduced verbal episodic memory and entorhinal cortex volume in younger middle-aged women with risk-reducing early ovarian removal.

Introduction: Women with early ovarian removal (<48 years) have an elevated risk for both late-life Alzheimer's disease (AD) and insomnia, a modifiable risk factor. In early midlife, they also show reduced verbal episodic memory and hippocampal volume. Whether these reductions correlate with a sleep phenotype consistent with insomnia risk remains unexplored.

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.

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.

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.

Conscious dance can be defined as unchoreographed, intentionally nonevaluative mindful movement commonly practiced in a group setting for purposes of authentic self-expression, self-discovery, interpersonal connectedness, and personal healing or growth.

Objective: To assess perceived effects of conscious dance practice (e.

Microemulsification of essential oils for the development of antimicrobial and mosquito repellent functional coatings for textiles.

Aims: To develop an essential oil (EO)-loaded textile coating using an environmentally friendly microemulsion technique to achieve both antimicrobial and mosquito repellent functionalities.

Methods And Results: Minimum inhibitory concentrations and fractional inhibitory concentrations of litsea, lemon and rosemary EOs were determined against Staphylococcus aureus, Escherichia coli, Staphylococcus epidermidis, Pseudomonas aeruginosa and Trichophyton rubrum. A 1 : 2 mixture of litsea and lemon EOs inhibited all the microorganisms tested and was incorporated into a chitosan-sodium alginate assembly by a microemulsification process.

Hepatic artery aneurysm in the setting of focal nodular hyperplasia.

Hepatic artery aneurysms (HAA) are rare and may be seen in the setting of infection and vascular disease. Clinical presentation is variable but many are found incidentally during imaging studies. The association of HAA with focal nodular hyperplasia (FNH) is rarely reported in literature.

The incidence of hydrocephalus among patients with and without spinal muscular atrophy (SMA): Results from a US electronic health records study.

Background: The incidence of hydrocephalus in the spinal muscular atrophy (SMA) population relative to the general population is currently unknown. Since the approval of nusinersen, an intrathecally administered drug for SMA, a small number of hydrocephalus cases among nusinersen users have been reported. Currently, the incidence of hydrocephalus in untreated SMA patients is not available, thereby making it difficult to determine if hydrocephalus is a side effect of nusinersen or part of SMA's natural history.

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.

Written expressive disclosure in adults with irritable bowel syndrome: A randomized controlled trial.

Background: The benefits of written expressive disclosure (WED) to health are documented in a variety of healthy and clinical populations. This study investigates the effect of WED on health-related outcomes in irritable bowel syndrome (IBS).

Methods: Adults (N = 189) meeting Rome III criteria for IBS were randomly assigned to write about their: (1) deepest thoughts and feelings about the most stressful life event of the past five years (n = 67), (2) deepest thoughts and feelings about their IBS (n = 61) or (3) daily activities in an objective manner (control condition; n = 61).

The effect of climbing chalk powder on the infectivity of human coronavirus OC43.

There does not appear to be any studies in the published literature on the stability of SARS-CoV-2 in climbing chalk powder (magnesium carbonate and/or calcium carbonate), which has been hypothesized to pose a potential risk of fomite transmission of coronavirus disease 2019 (COVID-19) within climbing gyms. The aim of this study was to determine the infectivity of a model human coronavirus HCoV-OC43 in the presence of climbing chalk powder on a dry plastic surface. The stability of HCoV-OC43 on a plastic surface dusted with climbing chalk powders (magnesium carbonate, calcium carbonate or a blended chalk) was determined by titration on BHK-21 fibroblast cells.

Improving young children's handwashing behaviour and understanding of germs: The impact of A Germ's Journey educational resources in schools and public spaces.

Context: Effective handwashing can prevent the spread of germs, including Covid-19. However, young children can lack a fundamental understanding of germ transfer. A Germ's Journey educational resources were designed to support young children in learning about germs and handwashing.

Evaluating approaches to designing effective Co-Created hand-hygiene interventions for children in India, Sierra Leone and the UK.

Effective and culturally appropriate hand-hygiene education is essential to promote health-related practices to control and prevent diseases such as Diarrhoea, Ebola and COVID-19. In this paper we outline and evaluate the Co-Creation processes underpinning a handwashing intervention for young children (A Germ's Journey) developed and delivered in India, Sierra Leone and the UK, and consider the implications surrounding Imperialist/Colonial discourse and the White Saviour Complex. The paper focuses both on the ways Co-Creation was conceptualised by our collaborators in all three countries and the catalysts and challenges encountered.
