Risk-based management of international sporting events during the COVID-19 pandemic.

Mass gatherings include a diverse range of events such as sporting competitions, religious ceremonies, entertainment activities, political rallies and cultural celebrations, which have important implications for population well-being. However, if not managed properly, these events can amplify health risks including those related to communicable diseases, and place undue strain on health systems in host countries and potentially in attendees' home countries, upon their return. The coronavirus disease 2019 (COVID-19) pandemic has provided a unique opportunity to evaluate the risk factors associated with mass gatherings and the effectiveness of applying mitigation measures during infectious disease emergencies. The pandemic has also allowed event organizers and health officials to identify best practices for mass gathering planning in host countries. To guide decisions about whether to hold, postpone, modify or cancel a mass gathering during the COVID-19 pandemic, the World Health Organization and its partners developed normative guidance and derivative tools promoting a risk-based approach to mass gathering planning. This approach involves three steps to guide decision-making around mass gatherings: risk evaluation, risk mitigation and risk communication. The approach was applied in the planning and execution of several mass gathering events, including the Tokyo 2020 and Beijing 2022 Olympic and Paralympic Games. Lessons identified from these large-scale international events offer insights into the planning and implementation of mass gathering events during a pandemic, and the broader impacts of such events on society. These lessons may also further inform and refine planning for future mass gatherings.

Les rassemblements de masse désignent un large éventail d'événements tels que des compétitions sportives, cérémonies religieuses, activités de divertissement, manifestations politiques et fêtes culturelles. Tous ont un impact considérable sur le bien-être de la population. Toutefois, s'ils ne sont pas gérés correctement, ils peuvent augmenter les risques sanitaires, notamment concernant les maladies transmissibles, et exercer une pression excessive sur les systèmes de santé des pays hôtes, voire sur ceux des pays d'origine des participants après leur retour. La pandémie de maladie à coronavirus 2019 (COVID-19) a offert une occasion unique d'évaluer les facteurs de risque associés aux rassemblements de masse, ainsi que l'efficacité des mesures visant à limiter la propagation dans des situations d'urgence liées à des maladies infectieuses. Cette pandémie a également permis aux organisateurs d'événements et responsables de santé d'identifier les bonnes pratiques à appliquer dans les pays hôtes pendant les rassemblements de masse. Afin de guider les décisions relatives au maintien, au report, à la modification ou à l'annulation d'un rassemblement de masse durant la pandémie de COVID-19, l'Organisation mondiale de la Santé et ses partenaires ont mis au point des orientations normatives et des outils dérivés favorisant une approche tenant compte des risques au moment de la planification. Cette approche comprend trois étapes contribuant à la prise de décision: l'évaluation, la réduction et la communication des risques. Elle a été déployée lors de la planification et de l'exécution de nombreux rassemblements de masse, comme les Jeux olympiques et paralympiques de Tokyo 2020 et Beijing 2022. Les leçons tirées de ces événements internationaux à grande échelle fournissent des informations sur leur organisation et leur mise en œuvre en cas de pandémie, ainsi que les impacts de tels événements sur la société. Elles sont en outre susceptibles de faciliter et d'améliorer la planification des futurs rassemblements de masse.

Las concentraciones masivas incluyen una gran variedad de eventos, como competiciones deportivas, ceremonias religiosas, actividades de entretenimiento, mítines políticos y celebraciones culturales, que tienen importantes implicaciones para el bienestar de la población. Sin embargo, si no se gestionan adecuadamente, estos eventos pueden amplificar los riesgos para la salud, incluidos los relacionados con las enfermedades transmisibles, y suponer una carga excesiva para los sistemas sanitarios de los países anfitriones y, potencialmente, de los países de origen de los participantes a su regreso. La pandemia de la enfermedad por coronavirus de 2019 (COVID-19) ha brindado una oportunidad única para evaluar los factores de riesgo asociados a las concentraciones masivas y la eficacia de aplicar medidas de mitigación durante las emergencias por enfermedades infecciosas. La pandemia también ha permitido a los organizadores de eventos y a las autoridades sanitarias identificar las mejores prácticas para la planificación de concentraciones masivas en los países anfitriones. Para orientar las decisiones sobre la celebración, el aplazamiento, la modificación o la cancelación de una concentración masiva durante la pandemia de la COVID-19, la Organización Mundial de la Salud y sus asociados elaboraron orientaciones normativas y herramientas derivadas que promueven un enfoque de la planificación de concentraciones masivas basado en los riesgos. Este enfoque consta de tres pasos para orientar la toma de decisiones en torno a las concentraciones masivas: la evaluación, la mitigación y la comunicación de riesgos. El enfoque se aplicó en la planificación y ejecución de varias concentraciones masivas, incluidos los Juegos Olímpicos y Paralímpicos de Tokio 2020 y Pekín 2022. Las conclusiones extraídas de estos eventos internacionales a gran escala permiten comprender mejor la planificación y ejecución de concentraciones masivas durante una pandemia, así como las repercusiones más generales de estos eventos en la sociedad. Estas lecciones también pueden informar y perfeccionar la planificación de futuras concentraciones masivas.

A high fiber diet or supplementation with Lactococcus lactis subspecies cremoris to pregnant mice confers protection against intestinal injury in adult offspring.

The diet during pregnancy, or antenatal diet, influences the offspring's intestinal health. We previously showed that antenatal butyrate supplementation reduces injury in adult murine offspring with dextran sulfate sodium (DSS)-induced colitis. Potential modulators of butyrate levels in the intestine include a high fiber diet or dietary supplementation with probiotics. To test this, we supplemented the diet of pregnant mice with high fiber, or with the probiotic bacteria Lactococcus lactis subspecies cremoris or Lactobacillus rhamnosus GG. We then induced chronic colitis with DSS in their adult offspring. We demonstrate that a high fiber antenatal diet, or supplementation with Lactococcus lactis subspecies cremoris during pregnancy diminished the injury from DSS-induced colitis in offspring. These data are evidence that antenatal dietary interventions impact offspring gut health and define the antenatal diet as a therapeutic modality to enhance offspring intestinal health.

Just-in-time adaptive interventions for adolescent and young adult health and well-being: protocol for a systematic review.

INTRODUCTION: Health behaviours such as exercise and diet strongly influence well-being and disease risk, providing the opportunity for interventions tailored to diverse individual contexts. Precise behaviour interventions are critical during adolescence and young adulthood (ages 10-25), a formative period shaping lifelong well-being. We will conduct a systematic review of just-in-time adaptive interventions (JITAIs) for health behaviour and well-being in adolescents and young adults (AYAs). A JITAI is an emerging digital health design that provides precise health support by monitoring and adjusting to individual, specific and evolving contexts in real time. Despite demonstrated potential, no published reviews have explored how JITAIs can dynamically adapt to intersectional health factors of diverse AYAs. We will identify the JITAIs' distal and proximal outcomes and their tailoring mechanisms, and report their effectiveness. We will also explore studies' considerations of health equity. This will form a comprehensive assessment of JITAIs and their role in promoting health behaviours of AYAs. We will integrate evidence to guide the development and implementation of precise, effective and equitable digital health interventions for AYAs. METHODS AND ANALYSIS: In adherence to Preferred Reporting Items for Systematic Review and Meta-Analysis guidelines, we will conduct a systematic search across multiple databases, including CENTRAL, MEDLINE and WHO Global Index Medicus. We will include peer-reviewed studies on JITAIs targeting health of AYAs in multiple languages. Two independent reviewers will conduct screening and data extraction of study and participant characteristics, JITAI designs, health outcome measures and equity considerations. We will provide a narrative synthesis of findings and, if data allows, conduct a meta-analysis. ETHICS AND DISSEMINATION: As we will not collect primary data, we do not require ethical approval. We will disseminate the review findings through peer-reviewed journal publication, conferences and stakeholder meetings to inform participatory research.

Understanding the behavioral determinants of adolescents' water consumption: A cross-country comparative study.

Substituting the consumption of sugar-sweetened beverages (SSB) with that of water can have a positive effect on adolescents' health. However, despite the attention on this topic in the Global North, it is relatively understudied in other regions of the world, such as the Caribbean. To guide the development of future interventions, understanding the factors determining water consumption among Caribbean adolescents is important. This study examined the behavioral determinants of water consumption among adolescents in Aruba (the Caribbean) and compared them to those in the Netherlands (Western Europe). We used a theoretical model that integrates the dominant theoretical perspectives in the field of public health, including theories of planned behavior, social norms, and intrinsic motivation. This cross-country study included 1,584 adolescents from Aruba and the Netherlands (52% girls; M = 12.34 years; SD = 2.14). The data were analyzed using regression analyses. This study found that in Aruba, adolescents with higher scores of intrinsic motivation, friends' descriptive norms, attitudes, and behavioral control regarding water consumption drank more water. Moreover, the associations between water consumption and both intrinsic motivation as well as friends' descriptive norms for adolescents in Aruba were stronger than those found in the Netherlands. These associations imply that it is even more important for Aruban adolescents than Dutch adolescents to be intrinsically motivated or to perceive their friends often consuming water to drink more water. The cross-country comparison implies that future interventions in Aruba aimed at increasing adolescents' water consumption as an alternative to SSB should focus on enhancing their intrinsic motivation while considering their friends' social norms.

Harlequin Ichthyosis in a 4-year-old male: Case report

@#Harlequin ichthyosis (HI) is a rare type of congenital keratinization disorder that, when left untreated, usually leads to early neonatal demise. A clinical diagnosis of HI is considered when a patient presents with thick plate-like scaling of the skin together with eclabium, ectropion, and nasal hypoplasia. The diagnosis can be confirmed by genetic testing to determine mutation in the adenosine triphosphate-binding cassette A12 (ABCA12) gene. Early administration of systemic retinoids to promote desquamation and emollients to control excessive scaling and dryness of the skin lead to better prognosis in most cases of HI. We present the case of a 4-year-old male with HI who has been successfully managed with bland emollients and systemic acitretin therapy, which we started when he was 1 year old.
