Forensic science: Where to from Here?

'Where to from Here' (WTFH) was the theme chosen for the 2023 meeting of the International Association of Forensic Sciences (IAFS). This theme reflects the fact that forensic science is evolving rapidly, not only within individual sub-disciplines but, critically, across the whole forensic science landscape. Identifying and predicting evolutionary change will enable a more focused and constructive future for forensic science.

Toothbrushing programme in Saudi Arabia 'TOPS': a study protocol for a cluster randomised controlled trial in kindergartens, Riyadh.

Introduction: Dental caries among children is a major global health problem and is a particular public health challenge in Saudi Arabia. Dental caries cause pain, infection and negatively impact quality of life. As part of population oral health improvement efforts in Saudi Arabia, this project aims to evaluate the effectiveness of a supervised toothbrushing programme in kindergartens.

Metabolic changes in response to varying whole-grain wheat and rye intake.

Epidemiological studies have shown associations between whole-grain intake and lowered disease risk. A sufficient level of whole-grain intake to reach the health benefits has not been established, and there is limited knowledge about the impact of whole-grain intake on metabolite levels. In this clinical intervention study, we aimed to identify plasma and urine metabolites associated with two different intake levels of whole-grain wheat and rye and to correlate them with clinical plasma biomarkers.

Healthy grocery delivery in the usual care for adults recovering from an acute coronary event: protocol for a three-arm randomised controlled trial.

Introduction: Coronary heart disease is a major contributor to the global burden of disease. Appropriate nutrition is a cornerstone of the prevention and treatment of coronary heart disease; however, barriers including cost and access to recommended foods limits long-term adherence for many. We are conducting, in adults with coronary heart disease, a randomised controlled trial comparing usual care with two dietary interventions in which usual care is augmented by 12 weeks free delivered groceries.

Worms and welfare: Behavioural and physiological changes associated with gastrointestinal nematode parasitism in lambs.

Parasitism with gastrointestinal nematodes (GIN) is a worldwide issue impacting negatively on animal production, health, and welfare. Therefore, early diagnostic signs of parasitism are required to allow for timely interventions. The objective of this study was to evaluate the behavioural and physiological changes in lambs associated with GIN infection.

Metabolomic evolution of the postpartum dairy cow uterus.

High rates of early pregnancy loss are a critical issue in dairy herds, particularly in seasonal, grazing systems. Components of the uterine luminal fluid (ULF), on which the early embryo depends for sustenance and growth, partly determine early pregnancy losses. Here, changes in ULF from early to mid-postpartum in crossbred dairy cows were explored, linking them with divergent embryo development.

Quality Management in forensic science: A closer inspection.

An international survey was conducted on the benefits and limitations of accreditation to ISO17025 in forensic science, and how quality management could be improved to reflect the complexities of the end-to-end process. The survey was in response to growing concern within the forensic science community that the standard ISO17025 (and ISO17020), which is the backbone of forensic science accreditation, does not have sufficient depth and reach to properly address the quality of both the inputs (crime scene traces) and outputs (e.g.

Efficacy of Electrochemotherapy in Breast Cancer Patients of Different Receptor Status: The INSPECT Experience.

Electrochemotherapy has been proven to be an efficient treatment for cutaneous metastases of various cancers. Data on breast cancer (BC) patients with cutaneous metastases were retrieved from the INSPECT database. Patients were divided by their receptor status: HER2+, HR+ (ER/PgR+), and TN (triple negative).

European e-Delphi process to define expert consensus on electrochemotherapy treatment indications, procedural aspects, and quality indicators in melanoma.

Background: Skin metastases are an important co-morbidity in melanoma. Despite broad adoption, electrochemotherapy implementation is hindered by a lack of treatment indications, uncertainty regarding procedural aspects, and the absence of quality indicators. An expert consensus may harmonize the approach among centres and facilitate comparison with other therapies.

The Relationship between Whole-Grain Intake and Measures of Cognitive Decline, Mood, and Anxiety-A Systematic Review.

Greater intake of whole grains, compared to refined grains, is consistently associated with a reduced risk of cardiovascular disease and type 2 diabetes, both of which are associated with cognitive decline. To better understand the relationship between whole-grain intake, cognition, mood, and anxiety, a systematic review was conducted to synthesize available evidence linking whole grains to these outcomes. Four electronic databases were searched from inception to August 2021 for potentially relevant observational and interventional studies.

Perspectives on the future of dissemination and implementation research in oral and craniofacial sciences.

Dissemination and implementation science is a field of research that promotes the adoption and maintenance of evidence-based interventions in healthcare delivery and community settings and seeks to understand the processes by which such adoption and maintenance occur. While dissemination and implementation science is an established field in health services research, it is relatively new and making inroads in dental, oral and craniofacial research. This article summarizes the proceedings from a scientific panel on 'Dissemination and Implementation Science for Oral and Craniofacial Health' that was held during the international Behavioral and Social Oral Health Sciences Summit.

Molecular insights into quality and authentication of sheep meat from proteomics and metabolomics.

Sheep meat (encompassing lamb, hogget and mutton) is an important source of animal protein in many countries, with a unique flavour and sensory profile compared to other red meats. Flavour, colour and texture are the key quality attributes contributing to consumer liking of sheep meat. Over the last decades, various factors from 'farm to fork', including production system (e.

Evaluating childsmile, Scotland's National Oral Health Improvement Programme for children.

In the early 2000s, a Scottish Government Oral Health Action Plan identified the need for a national programme to improve child oral health and reduce inequalities. 'Childsmile' aimed to improve child oral health in Scotland, reduce inequalities in outcomes and access to dental services, and to shift the balance of care from treatment to prevention through targeted and universal components in dental practice, community and educational settings. This paper describes how an embedded, theory-based research and evaluation arm with multi-disciplinary input helps determine priorities and provides important strategic direction.

Risk prediction models for head and neck cancer: A rapid review.

Background: Cancer risk assessment models are used to support prevention and early detection. However, few models have been developed for head and neck cancer (HNC).

Methods: A rapid review of Embase and MEDLINE identified  = 3045 articles.

A qualitative study of organisational resilience in care homes in Scotland.

Providing care for the dependent older person is complex and there have been persistent concerns about care quality as well as a growing recognition of the need for systems approaches to improvement. The I-SCOPE (Improving Systems of Care for the Older person) project employed Resilient Healthcare (RHC) theory and the CARE (Concepts for Applying Resilience) Model to study how care organisations adapt to complexity in everyday work, with the aim of exploring how to support resilient performance. The project was an in-depth qualitative study across multiple sites over 24 months.

Rapid Evaporative Ionisation Mass Spectrometry fingerprinting can discriminate lamb meat due to different ageing methods and levels of dehydration.

Dry-ageing is a technique for developing characteristic dry-aged flavour through the interplay of dehydration, lipid oxidation and microbial activities. In this study, we tested the hypothesis that the extent of drying influences the metabolite profile and the final flavour of lamb using an "Age-and-Dry" regime; and that Rapid Evaporative Ionisation Mass Spectrometry (REIMS) fingerprinting can be used to discriminate the metabolic fingerprints of lambs due to ageing methods and dehydration levels. Lamb loins (n = 60) were dehydrated with low (12%), medium (17%) and high (22%) weight losses and compared with the wet-aged equivalents using REIMS and evaluated by 12-member sensory panel.

Head and neck cancer in the UK: what was the stage before COVID-19? UK cancer registries analysis (2011-2018).

Introduction People who present with more advanced stage head and neck cancer (HNC) are associated with poorer outcomes and survival. The burden and trends of advanced stage HNC are not fully known at the population level. The UK national cancer registries routinely collect data on HNC diagnoses.

Mass Spectrometry-Based Lipidomics of Brown Adipose Tissue and Plasma of New-Born Lambs Subjected to Short-Term Cold Exposure.

During cold exposure, brown adipose tissue (BAT) holds the key mechanism in the generation of heat, thus inducing thermogenic adaptation in response to cooler environmental changes. This process can lead to a major lipidome remodelling in BAT, where the increase in abundance of many lipid classes plays a significant role in the thermogenic mechanisms for heat production. This study aimed to identify different types of lipids, through liquid chromatography-mass spectrometry (LC-MS), in BAT and plasma during a short-term cold challenge (2-days), or not, in new-born lambs.

Differences in Metabolite Composition of Mill. Extracts Lead to Differential Effects on Human Blood T Cell Activity In Vitro.

Mill. (Aloe) is used for diverse therapeutic properties including immunomodulation. However, owing to the compositionally complex nature of Aloe, bioactive component(s) responsible for its beneficial properties, though thought to be attributed to polysaccharides (acemannan), remain unknown.

UV and visible light exposure to hair leads to widespread changes in the hair lipidome.

Objective: Scalp hair is among the most exposed parts of the human body, yet the impact of visible and UV light on hair lipids, an important structural component of hair, is poorly researched. We have used lipidomics, a broad-based approach to measure lipids in samples, which has hitherto not been applied to UV-exposed hair in the published literature, and could allow for a wider understanding of how UV light impacts on specific hair lipids.

Methods: Mixed blonde Caucasian hair switches were divided into two groups of five, with half of the hair switches exposed to UV and visible light mimicking normal daytime exposure and half left unexposed.

GENESISS 2-Generating Standards for In-Situ Simulation project: a systematic mapping review.

Background: In-situ simulation is increasingly employed in healthcare settings to support learning and improve patient, staff and organisational outcomes. It can help participants to problem solve within real, dynamic and familiar clinical settings, develop effective multidisciplinary team working and facilitates learning into practice. There is nevertheless a reported lack of a standardised and cohesive approach across healthcare organisations.

GENESISS 1-Generating Standards for In-Situ Simulation project: a scoping review and conceptual model.

Background: In-Situ Simulation (ISS) enables teams to rehearse and review practice in the clinical environment to facilitate knowledge transition, reflection and safe learning. There is increasing use of ISS in healthcare organisations for which patient safety and quality improvement are key drivers. However, the effectiveness of ISS interventions has not yet been fully demonstrated and requires further study to maximise impact.

Metabolic fingerprinting using Rapid evaporative ionisation mass spectrometry can discriminate meat quality and composition of lambs from different sexes, breeds and forage systems.

Assurance of food quality and allied farming systems is increasingly sought by consumers and food processors. Yet, there are no validated analytical approaches for food-based verification of farming systems. Rapid evaporative ionisation mass spectrometry (REIMS) is an emerging analytical tool that can provide sufficient details to meet this need.
