Pulmonary delivery of silver nanoparticles prevents influenza infection by recruiting and activating lymphoid cells.

Silver nanoparticles (AgNPs) are a potential antiviral agent due to their ability to disrupt the viral particle or alter the virus metabolism inside the host cell. In vitro, AgNPs exhibit antiviral activity against the most common human respiratory viruses. However, their capacity to modulate immune responses during respiratory viral infections has yet to be explored. This study demonstrates that administering AgNPs directly into the lungs prior to infection can reduce viral loads and therefore virus-induced cytokines in mice infected with influenza virus or murine pneumonia virus. The prophylactic effect was diminished in mice with depleted lymphoid cells. We showed that AgNPs-treatment resulted in the recruitment and activation of lymphocytes in the lungs, particularly natural killer (NK) cells. Mechanistically, AgNPs enhanced the ability of alveolar macrophages to promote both NK cell migration and IFN-γ production. By contrast, following infection, in mice treated with AgNPs, NK cells exhibited decreased activation, indicating that these nanoparticles can regulate the potentially deleterious activation of these cells. Overall, the data suggest that AgNPs may possess prophylactic antiviral properties by recruiting and controlling the activation of lymphoid cells through interaction with alveolar macrophages.

Informação e prevenção não farmacológica da COVID-19 no território de uma unidade de saúde da família em Pernambuco / Information and non-pharmacological prevention of COVID-19 in the territory of a family health unit in Pernambuco / Información y prevención no farmacológica del COVID-19 en el territorio de una unidad de salud de la familia en Pernambuco

Introdução: O conhecimento da magnitude em que a população implementa medidas de proteção emitidas pelas autoridades de saúde pública é essencial na prevenção da doença do novo coronavírus (COVID-19). A eficácia de medidas não farmacológicas de prevenção e das políticas públicas destinadas a reduzir o contágio pela COVID-19 depende de quão bem os indivíduos são informados sobre as consequências da infecção e as medidas que devem adotar para reduzir sua propagação. O entendimento, as atitudes e as práticas das pessoas em relação à COVID-19 e sua prevenção são basilares para a compreensão da dinâmica epidemiológica, demandando a realização de pesquisas sobre o cumprimento de medidas não farmacológicas de prevenção do contágio em diversos territórios. Para isso, em 2020, medidas não farmacológicas contra a COVID-19 foram divulgadas por fontes diversas, estatais e privadas, para a maior parte da população brasileira, com a finalidade de orientar comportamentos para conter a crise sanitária. As equipes da Estratégia Saúde da Família têm um papel fundamental neste processo de educação em saúde, pois compreendem elementos socioculturais das suas comunidades, alcançando-as tanto em capilaridade quanto em adequação local da informação técnico-científica. Este artigo abrange uma pesquisa de campo, parte de um projeto multicêntrico nacional. Objetivo: Avaliar se a população do território de uma unidade da Estratégia Saúde da Família da cidade de Condado-PE entende e aplica as informações que recebeu sobre medidas não farmacológicas de prevenção em suas práticas de proteção contra a COVID-19. Mais especificamente, a pesquisa visou determinar que informações foram recebidas pelos respondentes, quais as suas fontes, o grau de confiabilidade atribuído a estas, além da adesão deles às medidas não farmacológicas e sua relação com variáveis sociodemográficas. Métodos: O modelo do estudo foi observacional e descritivo, com abordagem quantitativa, a partir da coleta de dados primários com 70 usuários por entrevista presencial com questionário estruturado. Resultados: Os resultados mostraram que a população recebeu vasta informação sobre prevenção da doença. Conclusão: Com níveis variados de confiabilidade das fontes, atribuindo importância relevante às medidas de prevenção e adotou a maioria delas, com exceção do isolamento social total.

Introduction: Knowledge of the magnitude to which the population implements protective measures issued by public health authorities is essential in preventing coronavirus disease 2019 (COVID-19). The effectiveness of non-pharmacological prevention measures (NPM) and public policies aimed at reducing the spread of COVID-19 depends on how well individuals are informed about the consequences of the infection and the measures they must adopt to reduce its spread. The understanding, attitudes, and practices of people in relation to COVID-19 and its prevention are fundamental for understanding the epidemiological dynamics, demanding research on compliance with NPM to prevent contagion in different territories. To this end, in 2020, NPM against COVID-19 were released by various sources, state and private, for most of the Brazilian population, with the aim of guiding behaviors to contain the health crisis. The Family Health Strategy (FHS) teams play a key role in this health education process, as they comprise sociocultural elements of their communities, reaching them both in capillarity and in local adequacy of technical-scientific information. This article covers field research, part of a national multicenter project. Objective: To evaluate whether the population of the territory of an FHS unit in the city of Condado, Pernambuco, understands and applies the information it received about NPM prevention in their practices to protect against COVID-19. More specifically, the research aimed to determine what information was received by the respondents, what are their sources, the degree of reliability attributed to these, in addition to their adherence to the NPM and their relationship with sociodemographic variables. Methods: The study model was observational and descriptive, with a quantitative approach, based on the collection of primary data with 70 users through face-to-face interviews with a structured questionnaire. Results: The results showed that the population received extensive information on disease prevention. Conclusion: With varying levels of reliability of the sources, attributing relevant importance to prevention measures and adopted most of them, with the exception of total social isolation.

El conocimiento de la magnitud con la que la población implementa las medidas de protección emitidas por las autoridades de salud pública es fundamental en la prevención de la enfermedad por coronavirus 2019 (COVID-19). La efectividad de las medidas de prevención no farmacológicas (MFN) y de las políticas públicas dirigidas a reducir la propagación de la COVID-19 depende de qué tan bien se informe a las personas sobre las consecuencias de la infección y las medidas que deben adoptar para reducir su propagación. La comprensión, actitudes y prácticas de las personas con relación al COVID-19 y su prevención son fundamentales para comprender la dinámica epidemiológica, exigiendo investigaciones sobre el cumplimiento de las MNF para prevenir el contagio en diferentes territorios. Con ese fin, en 2020, MNF contra el COVID-19 fueron divulgados por diversas fuentes, estatales y privadas, para la mayoría de la población brasileña, con el objetivo de orientar comportamientos para contener la crisis sanitaria. Los equipos de la Estrategia de Salud de la Familia (ESF) juegan un papel fundamental en este proceso de educación en salud, ya que integran elementos socioculturales de sus comunidades, alcanzándolas tanto en la capilaridad como en la adecuación local de la información técnico-científica. Este artículo aborda una investigación de campo, parte de un proyecto multicéntrico nacional, con el objetivo de evaluar si la población del territorio de una unidad de la ESF en la ciudad de Condado-PE comprende y aplica la información recibida sobre la prevención de MNF en sus prácticas de protección contra el COVID -19. Más específicamente, la investigación tuvo como objetivo determinar qué información recibieron los encuestados, cuáles son sus fuentes, el grado de confiabilidad atribuido a estas, además de su adherencia al MNF y su relación con variables sociodemográficas. El modelo de estudio fue observacional y descriptivo, con enfoque cuantitativo, basado en la recolección de datos primarios con 70 usuarios a través de entrevistas cara a cara con un cuestionario estructurado. Los resultados mostraron que la población recibió amplia información sobre prevención de la enfermedad, con diversos niveles de confiabilidad de las fuentes, atribuyendo importancia relevante a las medidas de prevención y adoptando la mayoría de ellas, con excepción del aislamiento social total.

Objetivo: O estudo teve por objetivo avaliar o Programa Nacional de Controle do Tabagismo (PNCT) em Mato Grosso do Sul, taxas de cobertura, abandono, cessação, uso de medicamentos, rede de serviços de saúde e as razões pelas quais algumas Equipes de Saúde da Família de Campo Grande ainda não aderiram ao programa. Métodos: Trata-se de uma pesquisa descritiva, com abordagem quantitativa, baseada em dados primários e secundários sobre o PNCT em Mato Grosso do Sul. Os dados primários foram obtidos por meio de questionário aplicado aos profissionais das Equipes de Saúde da Família (ESF) de Campo Grande, sem oferta do programa e avaliados quanto à frequência e presença de correlação entre as variáveis analisadas utilizando V de Cramer e teste de χ2. Os dados secundários foram obtidos do consolidado do Instituto Nacional de Câncer José Alencar Gomes da Silva com os registros produzidos pelos serviços. Resultados: As taxas de adesão, efetividade e apoio farmacológico na capital e interior foram: 66,80 e 59,79%; 20,58 e 34,91%; 32,14 e 99,86%, respectivamente. A oferta do programa ocorreu em 49,37% municípios e 43,85% das Unidades Básicas de Saúde (UBS) estimadas. Houve correlações entre ser capacitado e implantar o programa; treinamento de ingresso e oferta na UBS. As dificuldades relatadas pelos profissionais foram a pandemia de COVID-19, a sobrecarga e/ou equipe pequena e/ou falta de tempo e a ausência de capacitação/treinamento. Conclusões: O PNCT em Mato Grosso do Sul apresenta baixa cobertura e oferta restrita na rede de saúde, além do desempenho mediano de assistência aos tabagistas. Evidencia-se a necessidade de investimento em capacitação/treinamento, prioritariamente para as ESF de Campo Grande, dando-lhes condições de responder às necessidades de promoção da saúde, reconhecendo o programa como de maior custo-efetividade.

Objective: The objective of this study was to evaluate the National Tobacco Control Program (PNCT) in Mato Grosso do Sul, coverage rates, dropout, cessation, use of medication, the health services network and the reasons why Family Health Teams in Campo Grande have not yet joined the program. Methods: This was a descriptive study with a quantitative approach, based on primary and secondary data on the PNCT in Mato Grosso do Sul. The primary data were obtained by means of a questionnaire administered to Family Health Teams (ESF) in Campo Grande, which did not offer the program and evaluated the frequency and presence of correlation between the variables analyzed using Cramer's V test and the χ2 test. The secondary data were obtained from the consolidated records of the José Alencar Gomes da Silva National Cancer Institute with the records produced by the services. Results: The rates of adherence, effectiveness and pharmacological support in the capital and interior were: 66.80 and 59.79%; 20.58 and 34.91%; and 32.14 and 99.86%, respectively. The program was offered in 49.37% of the municipalities and 43.85% of the Basic Health Units (UBS) estimated. There were correlations between being trained and implementing the program and entry training and provision in the UBS. The difficulties reported by professionals were the COVID-19 pandemic, overload and/or a small team and/or lack of time and the absence of training. Conclusions: The PNCT in Mato Grosso do Sul has low coverage and restricted supply in the health network, in addition to average performance in assisting smokers. There is a clear need to invest in capacitation/training, primarily for the ESF in Campo Grande, enabling them to respond to the needs of health promotion, recognizing the program as more cost-effective.

Role of the screening with coronary computed tomography angiography on lipid management and risk factors control in an asymptomatic Chinese population: a community-based, parallel-group, open-label, randomized clinical trial (RESPECT2).

BACKGROUND: Lipid management based on cardiovascular risk level is the cornerstone of primary prevention of coronary artery disease (CAD), while the accuracy and adherence of traditional cardiovascular risk stratification have been questioned. Prevention strategies based on imaging screening for atherosclerotic plaques are found to be more objective and adherent in recent studies. This trial aims to investigate the role of coronary computed tomography angiography (CCTA) in guiding the primary prevention of CAD in a randomized controlled design. METHODS: Approximately 3400 middle-aged asymptomatic community participants will be recruited and randomized in a 1:1 ratio to a traditional cardiovascular risk score-guided (usual care group) or CCTA-guided (CCTA group) strategy. Participants with cardiovascular disease, prior lipid-lowering therapy, CCTA contraindication, or serious diseases that affect life span will be excluded. The intervention strategy includes blood pressure, blood glucose, and lipid management and lifestyle modifications. Blood pressure and glucose targets and lifestyle modification recommendations keep the same in both strategies, while lipid management is personalized based on traditional risk level or CCTA results, respectively. The primary outcome is the proportion of participants taking lipid-lowering medication regularly at both 6 and 12 months. The secondary outcomes include the proportion of participants achieving low-density lipoprotein cholesterol lowering targets at 12 months, mean changes in lipid levels from baseline to 12 months, barriers to adherence, adverse reactions related to CCTA examination, and cardiovascular events. DISCUSSION: The study is the first randomized clinical trial to examine the effectiveness of a CCTA-guided versus a traditional risk score-guided primary prevention strategy in an asymptomatic community-based population. TRIAL REGISTRATION: ClinicalTrials.gov NCT05725096. Registered on 2 February 2023.

Validation of a Community-Based Approach Toward Personalized Dementia Risk Reduction: The Kimel Family Centre for Brain Health and Wellness.

BACKGROUND/OBJECTIVES: The Kimel Family Centre for Brain Health and Wellness is a research-driven community centre testing the efficacy of personalized dementia risk reduction programming on dementia risk and cognition. The objective of this protocol is to validate this approach by following people for two years. DESIGN/SETTING: Participants will receive a comprehensive dementia risk assessment, including nonmodifiable and modifiable risk factors, from which they will receive a Personalized Dementia Risk Report and Program Strategy, indicating their health conditions increasing and their risk level in five modifiable risk domains: physical activity, brain-healthy eating, cognitive engagement, social connections, and mental wellbeing. Equipped with this information, participants will enroll in programs within the Centre to address their risk factors. Changes to their dementia risk, cognition, and Personalized Program Strategy will be communicated through re-assessments of risk factors every six months (risk and cognition) and every year (comprehensive assessment). PARTICIPANTS: Participants (n = 450) will be 50 years of age or older, without a diagnosis of dementia, and sufficiently fluent in English to complete the assessments and understand program instructors. One goal is that our participant sample will include people of low income (with fundraising providing free community centre membership), and from various ethno-racial backgrounds. INTERVENTION: Participants will select programs to meet their Personalized Program Strategy. For physical activity, they will gradually work toward the Canadian Society for Exercise Physiology guidelines. For brain-healthy eating, they will learn about the Brain Health Food Guide and food label reading, and then take additional programs. For cognitive engagement and mental wellbeing, they will take at least one hour of relevant programming per week. Social connections will be reinforced throughout all programs. All participants will also have access to the Canadian Consortium on Neurodegeneration's CAN-THUMBS Up online, educational program on modifiable dementia risk factors, called Brain Health PRO. MEASUREMENTS: The comprehensive assessment includes numerous dementia risk factors, but the primary measures are risk in the five domains, health conditions proximal to those five risk domains, and cognition, and how these are affected by adherence and quality of goal-directed future simulation. We hypothesize a reduced risk in the five domains within six months, improvements in health biomarkers within a year, and maintenance of cognition within two years, with these benefits accruing with greater adherence, but only up to a point, at which benefits will plateau, and greater benefits among participants whose goal-directed simulations are more vivid, personally-relevant, achievable, and positive. CONCLUSIONS: This innovative approach overcomes a number of limitations present in prior multidomain dementia prevention trials. Adapting a preference clinical trial that is embedded in a community centre, where participants have autonomy to choose programs to address their modifiable dementia risk factors, has real-world applicability in the global effort to reduce dementia risk.

A Pilot Study of BRAIN BOOTCAMP, a Low-Intensity Intervention on Diet, Exercise, Cognitive Activity, and Social Interaction to Improve Older Adults' Dementia Risk Scores.

BACKGROUND: Little is known about the impact of short, low-intensity multidomain dementia risk reduction interventions in older adults. OBJECTIVES: To examine the effectiveness and feasibility of a low-intensity multidomain lifestyle intervention on dementia risk and dementia literacy in Australian older adults. DESIGN: Single-group pre-post design. SETTING: Community-dwelling. PARTICIPANTS: A total of 853 older Australians (Mean age=73.3 years, SD=6.1) recruited from the community. INTERVENTION: A 3-month dementia risk reduction program, BRAIN BOOTCAMP, including education, personalised risk information, physical cues for healthier choices and goal setting and planning to target four modifiable risk factors of diet, exercise, cognitive activity and social interaction in older adults. MEASUREMENTS: The 'LIfestyle for BRAin health' (LIBRA) index was used to assess participants' modifiable dementia risk based on 12 factors, with higher scores indicating greater risk. Dementia literacy was measured using a modified questionnaire derived from Dutch and British surveys, encompassing knowledge, risk reduction, and awareness aspects. Paired t-tests were used to compare dementia risk scores and dementia literacy before and after the program. Multivariate regressions were performed to identify sociodemographic and psychological factors associated with change in the LIBRA index. RESULTS: Program attrition was high (58.3%). Participants who completed the program had decreased dementia risk scores (Cohen's d=0.59, p<0.001), increased dementia literacy and awareness (Cohen's d=0.64, p<0.001) and increased motivation to change lifestyle behaviors (Cohen's d=0.25-0.52, p<0.016). Participants with higher motivational beliefs had greater dementia risk reduction. CONCLUSIONS: Improving older adults' motivation and knowledge may help modify lifestyle behaviors to reduce dementia risk. However, program attrition remains a challenge, suggesting the need for strategies to enhance participant engagement and retention in such interventions.

Potentially Modifiable Dementia Risk Factors in Canada: An Analysis of Canadian Longitudinal Study on Aging with a Multi-Country Comparison.

BACKGROUND: It has been suggested that up to 40% of dementia cases worldwide are associated with modifiable risk factors; however, these estimates are not known in Canada. Furthermore, sleep disturbances, an emerging factor, has not been incorporated into the life-course model of dementia prevention. OBJECTIVE: To estimate the population impact of 12 modifiable risk factors in Canadian adults including sleep disturbances, by sex and age groups, and to compare with other countries. DESIGN: Cross-sectional analysis of Canadian Longitudinal Study on Aging baseline data. SETTING: Community. PARTICIPANTS: 30,097 adults aged 45 years and older. MEASUREMMENTS: Prevalence and Population Attributable Fractions (PAFs) associated with less education, hearing loss, traumatic brain injury, hypertension, excessive alcohol, obesity, smoking, depression, social isolation, physical inactivity, diabetes, and sleep disturbances. RESULTS: The risk factors with the largest PAF were later life physical inactivity (10.2%; 95% CI, 6.8% to 13%), midlife hearing loss (6.5%; 3.7% to 9.3%), midlife obesity (6.4%; 4.1% to 7.7%), and midlife hypertension (6.2%; 2.7% to 9.3%). The PAF of later life sleep disturbances was 3.0% (95% CI, 1.8% to 3.8%). The 12 risk factors accounted for 51.9% (32.2% to 68.0%) of dementia among men and 52.4% (32.5% to 68.7%) among women. Overall, the combined PAF of all risk factors was 49.2% (31.1% to 64.9%), and it increased with age. CONCLUSION: Nearly up to 50% of dementia cases in Canada are attributable to 12 modifiable risk factors across the lifespan. Canadian risk reduction strategies should prioritize targeting physical inactivity, hearing loss, obesity, and hypertension.

[Analysis of the Effectiveness of a Fall Prevention Program Incorporating an Interprofessional Team Collaboration Model on Reducing Fall Risk in Elderly Living in Long-term Care Facilities].

BACKGROUND: Concurrent with population ageing, falls have become a significantly more challenging public health issue among older adults. Three years of data collected recently from a nursing home in northern Taiwan reveals an increasing trend in fall density that is primarily associated with aging, physiological decline, chronic diseases, polypharmacy, osteoporosis, and lack of exercise. The percentage of nursing home residents at high risk of falls is currently at 12.6%, and the fall rate has been reported as reaching as high as 30% annually. PURPOSE: A fall prevention program was implemented to reduce the fall incidence rate to 18%, with secondary goals of improving fall prevention awareness, behavior, self-efficacy, lower limb muscle strength, balance, and gait by 10% on average, respectively, between pre-test and post-test. RESOLUTION: From September 30, 2023 to February 29, 2024, a health promotion activity and fall prevention exercise course were implemented using an interdisciplinary team collaboration model over a six-week period, providing individualized exercise for the participants. RESULTS: The study included 20 older adults with an average age of 88 years. Most (90%; n = 18) had chronic diseases, 25% (n = 5) were on more than nine medications, 70% (n = 14) had reduced bone mass, and 40% (n = 8) were at high risk of falls, with a fall incidence rate of 30% during the immediately preceding year. Post-intervention, the fall incidence rate dropped to 5%, fall prevention awareness, behavior, and self-efficacy increased by 18.3%, and lower limb muscle strength, balance, and gait improved by 11.7%. The post-test results in fall prevention awareness, behavioral changes, self-efficacy, and lower limb strength, balance, and gait were all significantly better than pre-test results, with all results achieving statistical significance. CONCLUSIONS: The project results support the positive effects of the developed intervention effectively on elderly physical fitness and fall risk, providing valuable insights for the implementation of fall prevention strategies in nursing homes.

Who should be screened for colorectal cancer and how can it be prevented more effectively?

In this editorial, we comment on the article published by Agatsuma et al in a recent issue of the World J Gastroenterol (2024; 30: 1368-1376). We firmly concur with Agatsuma et al regarding the vital significance of colorectal cancer (CRC) screening as a public health strategy to diminish disease burden. Individuals exposed to risk factors for CRC, those with comorbid conditions, and those with limited health literacy should undergo screening. However, we believe that more regular screenings should be accompanied by a greater focus on primary prevention (PP) of CRC. CRC remains a significant global health challenge, and its incidence is strongly linked to age, lifestyle, and socioeconomic factors. It is particularly noteworthy that the majority of CRC patients are diagnosed outside of established screening pathways and frequently at an advanced stage of the disease, and the majority of patients possess inadequate or even nonexistent knowledge regarding CRC, which significantly impacts the prognosis and imposes a substantial economic burden. This study revealed that CRC identified during hospital visits for comorbid conditions was typically diagnosed at an earlier stage than detected via symptomatic pathways. Remarkably, early incidental detection of CRC aligns closely with the timing of discovery through routine cancer screenings. This suggests that by adopting more inclusive screening protocols that combine opportunistic testing with traditional screening methods, health care systems can create a more comprehensive safety net for individuals at risk of CRC. However, before maximizing the health benefits of screening programs, it is essential to make additional efforts prior to screening, such as raising awareness via public education, risk assessment, and personalized recommendations, enhancing the knowledge and skills of health care professionals, optimizing the accessibility and convenience of screening processes, ensuring the quality and safety of screening services, strengthening follow-up and support systems, and providing policy support and financial investment. The establishment of a comprehensive screening system often requires substantial investment in human, material, and financial resources, which can be challenging to achieve in regions with limited health care resources. Strengthening PP strategies can reduce the disease burden by targeting the cause, representing a more cost-effective and impactful approach. Establishing a comprehensive cancer PP service platform that integrates authoritative public education on malignant tumor PP, individualized malignant tumor risk assessment, and self-health management assistance accessible to the entire population will significantly enhance the overall effectiveness of CRC PP strategies.

Postoperative delirium: A tragedy for elderly cancer patients.

In this editorial, we comment on the article by Hu et al entitled "Predictive modeling for postoperative delirium in elderly patients with abdominal malignancies using synthetic minority oversampling technique". We wanted to draw attention to the general features of postoperative delirium (POD) as well as the areas where there are uncertainties and contradictions. POD can be defined as acute neurocognitive dysfunction that occurs in the first week after surgery. It is a severe postoperative complication, especially for elderly oncology patients. Although the underlying pathophysiological mechanism is not fully understood, various neuroinflammatory mechanisms and neurotransmitters are thought to be involved. Various assessment scales and diagnostic methods have been proposed for the early diagnosis of POD. As delirium is considered a preventable clinical entity in about half of the cases, various early prediction models developed with the support of machine learning have recently become a hot scientific topic. Unfortunately, a model with high sensitivity and specificity for the prediction of POD has not yet been reported. This situation reveals that all health personnel who provide health care services to elderly patients should approach patients with a high level of awareness in the perioperative period regarding POD.

Generation Rx: evaluation of medication misuse prevention education for older adults.

Objective: Increased medication misuse over the last two decades has prompted extensive discussion about the lack of evidence-based and evidence-informed prevention education programs targeting the topic. As older adults are high utilizers of medications, this is an important population to reach with such educational programming. This study was designed to assess the change in knowledge and behavioral intentions of older adult participants after attending an educational session focused on safe medication use utilizing the Generation Rx Older Adult Toolkit (GROAT) resources. Methods: The Generation Rx team at The Ohio State University College of Pharmacy (OSU COP) partnered with The Ohio State University Extension offices (OSU Extension) across the state of Ohio to provide GROAT educational programming in their communities. OSU Extension Educators were trained via the standardized virtual training program, Generation Rx Ambassadors. Program participants were surveyed immediately before and after the educational events. Pre- and post-survey data was then analyzed to assess knowledge gain and behavioral intentions about safe medication practices, as well as program perception and program satisfaction. Results: Programming occurred between May 2022 and September 2022. In total, OSU Extension Educators collectively engaged 843 individuals in a prevention education program utilizing the GROAT materials. After excluding participants under 50 years of age, there were 297 pre surveys and 245 post surveys included in the data analysis. Knowledge gains from pre- to post-survey showed a significant increase in correct responses in seven of the eight questions asked regarding safe medication practices. All five questions evaluating behavioral intentions demonstrated positive results after the programming (p < 0.001). Participants' perceptions and program satisfaction were also favorable. Conclusion: This study found through pre- and post-survey results that the Generation Rx Older Adult Toolkit programming delivered by Generation Rx trained OSU Extension Educators significantly increased older adult participants' knowledge and favorably impacted behavioral intentions around safe medication use practices.

Eligibility for marine omega-3 fatty acid supplementation after acute coronary syndromes.

Background and aims: The 2019 European Society of Cardiology guidelines for the management of dyslipidemia consider the use of high-dose marine omega-3 fatty acid (FA) eicosapentaenoic acid (EPA) supplementation (icosapent ethyl 2 × 2g/day) to lower residual cardiovascular risk in high-risk patients with hypertriglyceridemia. This study aimed to assess the eligibility for omega-3 FA-EPA supplementation in patients with acute coronary syndromes (ACS). Methods: In a prospective Swiss cohort of patients hospitalized for ACS, eligibility for marine omega-3 FA-EPA, defined as plasma triglyceride levels ranging from 1.5 to 5.6 mmol/l, was assessed at baseline and one-year follow-up and compared across subgroups. Lipid-lowering therapy intensification with statin and ezetimibe was modelled to simulate a hypothetical systematic treatment and its effect on omega-3 FA-EPA supplementation eligibility. Results: Of 2643 patients, 98 % were prescribed statin therapy at discharge, including 62 % at a high-intensity regimen; 93 % maintained it after one year, including 53 % at a high-intensity regimen. The use of ezetimibe was 3 % at discharge and 7 % at one year. Eligibility was observed in 32 % (32 % men, 29 % women) one year post-ACS. After modelling systematic treatment with statins, ezetimibe, and both, eligibility decreased to 31 %, 25 % and 24 %, respectively. Eligibility was higher in individuals aged <70 (34 vs 25 %), smokers (38 vs 28 %), diabetics (46 vs 29 %), hypertensive (35 vs 29 %), and obese patients (46 vs 22 % for normal weight), all with p-values <0.001. Conclusion: In a contemporary Swiss cohort of patients with ACS, up to 32 % would be eligible for omega-3 FA-EPA supplementation one year after ACS, highlighting an opportunity to mitigate residual cardiovascular risk in patients with ACS and hypertriglyceridemia.

Effect of community attitudes on suicide mortality in South Korea: a nationwide ecological study.

Background: Attitudes toward suicide are essential in suicide prevention, as suicide is socio-culturally nuanced. Although the relationship between individual attitudes and suicidal behavior has been extensively studied, the effect of community attitudes-aggregated by region-on suicide mortality remains ambiguous. This study explored the association between community attitudes and real-world suicide mortality. Methods: Data on attitudes toward suicide from the 2018 Korea National Suicide Survey (N = 1500) and individual mortality data from the MicroData Integrated System were obtained. Confirmatory factor analysis supported a factor structure with three factors: "Permissiveness," "Unjustified behavior," and "Readiness to help/Preventability." Thirty regional units in South Korea aggregated the data for ecological analysis. We used negative binomial models to examine the association at the regional level, and stratified analysis by gender and age group was conducted. Results: "Permissiveness" was associated with reduced suicide rates in a univariate model (P < 0.001). Adjusting for gender, age, and additional sociodemographics did not alter the association. Additionally, this relationship was observed in males and individuals under 60 years of age after stratification. However, "Unjustified Behavior" and "Readiness to help/Preventability" exhibited no significant association with suicide in any model or stratum. Conclusion: The observed inverse association between permissive community attitudes and suicide contradicts the findings of previous research that links permissive individual attitudes to increased suicidal behavior. Our findings suggest that attitudes may operate differently at the individual and group levels. Although the cross-sectional design and single-country focus of this study warrant further investigation, our findings indicate that attitudes are significant contextual factors in the process of suicide, which could lead to novel approaches in suicide prevention.

Recognizing and preventing complications regarding bioresorbable scaffolds during coronary interventions.

The evolution of coronary intervention techniques and equipment has led to more sophisticated procedures for the treatment of highly complex lesions. However, as a result, the risk of complications has increased, which are mostly iatrogenic and often include equipment failure. Stent dislodgement warrants vigilance for the early diagnosis and a stepwise management approach is required to either expand or retrieve the lost stent. In the era of bioresorbable scaffolds that are not radiopaque, increased caution is required. Intravascular imaging may assist in detecting the lost scaffold in cases of no visibility fluoroscopically. Adequate lesion preparation is the key to minimizing the possibility of equipment loss; however, in the case that it occurs, commercially available and improvised devices and techniques may be applied.

Implementation of the cervical cancer prevention policy in one of the regions of Lithuania.

INTRODUCTION: Although the Lithuanian government increases funding for the cervical cancer prevention program every year, the incidence and mortality rates of cervical cancer are among the highest in Europe. In order to improve the prevention policy regarding cervical cancer, it is necessary to investigate the implementation of the cervical cancer prevention policy in one of the regions in Lithuania. METHODS: A quantitative survey method using a questionnaire, was applied in one of the regions of Lithuania. The study was conducted in the period 1-18 April 2022. During the study, 213 residents of the investigating region were interviewed. RESULTS: Respondents evaluated the cervical cancer prevention program in the investigated region positively, but not all women received invitations to participate in this program. The research revealed that the residents of the city of investigation have received this invitation more often than the women living in other districts. CONCLUSIONS: Women's opinion about the effectiveness of the cervical cancer prevention program is positive. Still, there is an emphasis on the wish that this program could be used from an the age of 25 years and continue to 59 years. The prevention program could be carried out more often than is currently established.

A systematic review and network meta-analysis on the effectiveness of exercise-based interventions for reducing the injury incidence in youth team-sport players. Part 1: an analysis by classical training components.

OBJECTIVES: The primary purposes were (a) to estimate the pooled effects of injury prevention programs (IPPs) on reducing overall and some specific body regions (lower extremity, thigh, knee, and ankle) injury incidence rates (IIRs) and (b) to compare the effects of single- and multi-component IPPs on mitigating injury risk in youth team sport athletes. A secondary objective was to explore the individual effects of different components on these IIRs. MATERIALS AND METHODS: Searches were performed up to 15 January 2024 in PubMed, Web of Science, SPORTDiscus, and Cochrane Library. Eligible criteria were: exercise-based interventions evaluated against a control group, overall IIRs were reported, and youth (≤19 years old) team sport players. Two reviewers extracted data and assessed trial quality using the Consolidated Standards of Reporting Trials (CONSORT) statement, the Physiotherapy Evidence Database Scale (PEDro), and a risk of bias tool (Cochrane Back and Neck Group). Pooled effects were calculated by Frequentist random effects pairwise and network meta-analyses. RESULTS: Twenty-one studies were included. IPPs reduced overall, lower extremities, thigh, knee, and ankle IIRs by an average of approximately 35%. Most of the IPPs demonstrated statistically significant risk mitigation effects for overall and lower extremity injuries compared to control group. Interventions comprised exclusively of strength ([IRR = 0.3 [95%CI = 0.10-0.93]) and flexibility (IRR = 0.49 [95%CI = 0.36-0.68]), as well as those including stability exercises, were the most effective measures for reducing injuries in youth team sports. CONCLUSIONS: The implementation of current IPPs in training sessions for several weeks has shown to be an effective strategy for reducing the risk of injury in youth team sport athletes by one-third. Indirect evidence suggests that strength, flexibility, and stability might be exercise components with the highest risk mitigation effects; however, more research is crucial to confirm our estimates with direct evidence.

Injury prevention programs could reduce around one-third the incidence of injuries occurring in youth team sport athletes.Strength, flexibility, and stability seem to be key exercise-based components to be included in any training program aimed at minimizing the risk of injury in youth.Further research comparing head-to-head injury prevention programs in youth athletes is needed to make more founded conclusions on their true risk mitigation effects.

What is known about suicide prevention gatekeeper training and directions for future research.

INTRODUCTION: Suicide prevention training that teaches skills to support a person experiencing thoughts of suicide and create community support networks, often termed, "gatekeeper" training (GKT), has been a longstanding pillar of international, national, and local suicide prevention efforts. GKT aims to improve knowledge, attitudes, and self-efficacy in identifying individuals at risk for suicide, hopefully enhancing one's willingness and ability to intervene with a person experiencing a crisis. However, little is known about GKT's effectiveness in creating the essential behavior change (e.g., increase in intervening behaviors) it sets out to accomplish. METHODS: This paper explores the history and theoretical background of GKT, reviews the current state of research on GKT, and provides framing and recommendations for next steps to advance research and practice around GKT. RESULTS & CONCLUSION: Through positioning GKT appropriately within the field of suicide prevention, we argue that the field of suicide prevention needs more rigorous research around GKT that includes long-term follow-up data on usage of skills learned during training, data on outcomes of those who have received an intervention from a trained gatekeeper, and the integration of implementation science to further our understanding of which trainings are appropriate for which helpers.

A Multi-State Examination of School District Policies to Address Teen Dating Violence.

In 2021, 13.6% of United States (U.S.) high school students reported experiencing teen dating violence (TDV). Most states have at least one law for addressing TDV in high schools through policies and/or educational programs. Limited research has been done to analyze the content and variability of school district TDV policies across the U.S., and its association with TDV victimization. Twenty-three large urban school districts across the U.S. were included in the analysis. School district TDV policies were obtained through an online search and were coded for the presence or absence of information pertaining to the scope, prevention education, response to TDV, and implementation of the policy. Self-reported TDV victimization was also obtained for each school district from the 2021 Youth Risk Behavior Survey. Overall, 18 school districts had a written TDV policy available online, with 15 school districts defining TDV in the policy. In terms of prevention education, only two school districts used culturally responsive language for diverse populations in the policy. Although 17 school districts included disciplinary consequences for TDV perpetration in the policy, only 6 school districts specified the consequences. All school districts with a TDV policy designated a liaison for TDV coordination. Overall, the prevalence and odds of self-reported TDV victimization was higher in school districts without a TDV policy compared to school districts with a TDV policy. Although most of the school districts had a TDV policy, there was substantial variation in the content of these TDV policies. Identifying and addressing gaps in school district TDV policies can potentially lead schools to preventing and responding to TDV more comprehensively, ultimately creating safer school environments.

Occurrence of adverse events following vaccination in patients with allergies: a prospective study.

OBJECTIVES: Allergic patients may be concerned about more frequent and/or more severe adverse events following vaccination, which may lead to the refusal of vaccines among these patients. The aim of this study is to assess whether allergic patients have more frequent adverse events (AEs) after vaccination than healthy individuals. METHODS: Study participants (N = 591) underwent vaccination of their choice at a selected Vaccination and Travel Medicine Centre. At a 10 to 14-day interval, they were contacted for a telephone questionnaire survey on the occurrence of AEs after vaccination. A group of allergic patients (n = 188) and healthy controls (n = 403) were followed in the study. RESULTS: No significant difference was found in the occurrence of AEs between study and control group. Only in redness and swelling, which was more common in allergic patients, but only in a few individuals. All side effects were minor, such as pain at the injection site or fatigue. No participant experienced a serious or life-threatening adverse event. In the studied group, no statistically significant differences were found even in the occurrence of AEs after singular vs. simultaneous administration of vaccines (p = 0.094), nor after vaccination with inactivated vs. attenuated vaccines (p = 0.655), or after vaccination against bacterial vs. viral infections (p = 0.140). CONCLUSIONS: Vaccination of allergic patients did not cause more frequent and/or more serious adverse events in our study compared to healthy people. If general contraindications are observed, then vaccination of allergic patients is considered safe.
