This work implements computational chemistry as a screening tool to aid in the coating and resin formulation process. Conceptual Density Functional theory (DFT) reactivity descriptors like the global chemical hardness and the dual descriptor Fukui function identify the tendency of polyester-melamine coatings to undergo electrophilic and nucleophilic attack during weathering exposure. Coatings were subjected to natural and accelerated weathering tests, with periodic infrared spectroscopy, colour, and gloss measurements to assess for the degree of changes brought about through photodegradation.

Article Synopsis
  • Organically coated steels are important for outdoor applications due to their need for strong corrosion resistance, typically enhanced by fossil fuel-derived clearcoats.
  • A study explored using tetraethoxysilane (TEOS)-based sol-gel coatings on polyurethane-coated steels, varying TEOS concentration to assess effectiveness.
  • The 10% TEOS concentration produced dense, uniform coatings with significantly better corrosion resistance, while the 2.5% concentration resulted in poor coating quality, indicating the need for optimal TEOS levels in future sol-gel research.

A cornerstone of asthma management is maintaining physical activity (PA), but this may lead to increased exposure to, and deeper inhalation of, pollutants. Furthermore, children and adolescents may be more susceptible to the deleterious impacts of such exposures. Despite the recent air quality campaigns and media coverage surrounding the dangers of air pollution to respiratory health, few target children and their understanding of such issues.

Background: Air pollution is the second largest risk to health in Africa, and children with asthma are particularly susceptible to its effects. Yet, there is a scarcity of air pollution exposure data from cities in sub-Saharan Africa. We aimed to identify potential exposure reduction strategies for school children with asthma living in urban areas in sub-Saharan Africa.

Promoting online peer support beyond the informal sector to statutory health services requires ethical considerations and evidence-based knowledge about its impact on patients, health care professionals, and the wider health care system. Evidence on the effectiveness of digital interventions in primary care is sparse, and definitive guidance is lacking on the ethical concerns arising from the use of social media as a means for health-related interventions and research. Existing literature examining ethical issues with digital interventions in health care mainly focuses on apps, electronic health records, wearables, and telephone or video consultations, without necessarily covering digital social interventions, and does not always account for primary care settings specifically.

Objectives: The emergency department (ED) represents a place and moment of opportunity to provide interventions to improve long-term asthma outcomes, but feasibility, effectiveness and mechanisms of impact are poorly understood. We aimed to review the existing literature on interventions that are delivered in the ED for adults and adolescents, targeting asthma outcomes beyond the ED, and to code the interventions according to theory used, and to understand the barriers and facilitators to their implementation.

Methods: We systematically searched seven electronic databases and research registers, and manually searched reference lists of included studies and relevant reviews.

Background: There is limited evidence of the longer-term impact of the COVID-19 pandemic on acute admissions for psychosis in the UK.

Aims: We examined the impact of COVID-19 on rates of admissions for first and repeated episode psychosis, and changes in patient profile and seasonal patterns, over a period of 12 months.

Method: We conducted a retrospective case note review of all patients admitted with a primary psychosis (F20-29 ICD 10 diagnosis) to an NHS psychiatric inpatient unit.

Objectives: The objectives of this systematic review are to identify studies that assess the effectiveness of patient-directed financial incentive interventions to improve asthma management behaviours, determine overall effectiveness of financial incentives, identify design characteristics of effective interventions and assess the impact on longer-term outcomes in the context of asthma.

Design: Systematic review with narrative synthesis.

Data Sources: Electronic databases (MEDLINE, Embase, Global Health, PsycINFO, CINAHL, PubMed and Web of Science) and grey literature sources (NHS Digital, CORE, ProQuest, Clinical Trials Register and EU Clinical Trials Register) were searched in November 2021 and updated March 2023.

Article Synopsis
  • About 4.3 million adults in the UK have asthma, and many of them struggle to manage it well, which can lead to more doctor visits and a lower quality of life.
  • The project focuses on creating a program for doctors to help patients connect with an online community for asthma support, aiming to improve self-management.
  • The study will gather feedback through surveys from about 3,000 asthma patients and will invite 50 interested individuals to participate in a meeting to learn about online support options.

Background: Overprescription of short-acting beta-agonist (SABA) inhalers and blood eosinophil count have strong associations with exacerbation risk in asthma. However, in the authors' recent publication only a minority of patients overprescribed SABA (≥6 inhalers in 12 months) were eosinophilic (≥0.3 x 10 cells/l).

Background: Since the previous Cochrane Review on this topic in 2016, debate has continued surrounding a potential role for vitamin D in reducing risk of asthma exacerbation and improving asthma control. We therefore conducted an updated meta-analysis to include data from new trials completed since this date.

Objectives: To evaluate the effectiveness and safety of administration of vitamin D or its hydroxylated metabolites in reducing the risk of severe asthma exacerbations (defined as those requiring treatment with systemic corticosteroids) and improving asthma symptom control.

Introduction: The successful scale-up of a latent tuberculosis (TB) infection testing and treatment programme is essential to achieve TB elimination. However, poor adherence compromises its therapeutic effectiveness. Novel rifapentine-based regimens and treatment support based on behavioural science theory may improve treatment adherence and completion.

Some subpopulations of migrants to Europe are generally healthier than the population of the country of settlement, but are at increased risk of key infectious diseases, including tuberculosis, HIV, and viral hepatitis, as well as under- immunisation. Infection screening programmes across Europe work in disease silos with a focus on individual diseases at the time of arrival. We argue that European health-care practitioners and policy makers would benefit from developing a framework of universal health care for migrants, which proactively offers early testing and vaccinations by delivering multi-disease testing and catch-up vaccination programmes integrated within existing health systems.
