Did the health care vaccine mandate work? An evaluation of the impact of the COVID-19 vaccine mandate on vaccine uptake and infection risk in a large cohort of Canadian health care workers.

BACKGROUND: We aimed to evaluate the impact of health care vaccine mandates on vaccine uptake and infection risk in a cohort of Canadian health care workers (HCWs). METHODS: We conduct interrupted time series analysis through a regression discontinuity in time approach to estimate the immediate and delayed impact of the mandate. Multilevel mixed effect modeling fitted with restricted maximum likelihood was used to estimate impact on infection risk. RESULTS: The immediate and sustained effects of the mandate was a 0.19% (P < .05) and a 0.012% (P < .05) increase in the daily proportion of unvaccinated HCWs getting their first dose, respectively. An additional 623 (95% confidence interval: 613-667) HCWs received first doses compared to the predicted uptake absent the mandate. Adjusted test positivity declined by 0.053% (95% confidence interval: 0.035%, 0.069) for every additional day the mandate was in effect. DISCUSSION: Our results indicate that the mandate was associated with significant increases in vaccine uptake and infection risk reduction in the cohort. CONCLUSIONS: Given the benefit that vaccination could bring to HCWs, understanding strategies to enhance uptake is crucial for bolstering health system resilience, but steps must be taken to avert approaches that sacrifice trust, foster animosity, or exacerbate staffing constraints for short-term results.

Public health and economic benefits of seasonal influenza vaccination in risk groups in France, Italy, Spain and the UK: state of play and perspectives.

BACKGROUND: Seasonal influenza epidemics have a substantial public health and economic burden, which can be alleviated through vaccination. The World Health Organization (WHO) recommends a 75% vaccination coverage rate (VCR) in: older adults (aged ≥ 65 years), individuals with chronic conditions, pregnant women, children aged 6-24 months and healthcare workers. However, no European country achieves this target in all risk groups. In this study, potential public health and economic benefits achieved by reaching 75% influenza VCR was estimated in risk groups across four European countries: France, Italy, Spain, and the UK. METHODS: A static epidemiological model was used to estimate the averted public health and economic burden of increasing the 2021/2022 season VCR to 75%, using the efficacy data of standard-dose quadrivalent influenza vaccine. For each country and risk group, the most recent data on population size, VCR, pre-pandemic influenza epidemiology, direct medical costs and absenteeism were identified through a systematic literature review, supplemented by manual searching. Outcomes were: averted influenza cases, general practitioner (GP) visits, hospitalisations, case fatalities, number of days of work lost, direct medical costs and absenteeism-related costs. RESULTS: As of the 2021/2022 season, the UK achieved the highest weighted VCR across risk groups (65%), followed by Spain (47%), France (44%) and Italy (44%). Based on modelling, the 2021/2022 VCR prevented an estimated 1.9 million influenza cases, avoiding 375,200 GP visits, 73,200 hospitalisations and 38,400 deaths. To achieve the WHO 75% VCR target, an additional 24 million at-risk individuals would need to be vaccinated, most of which being older adults and patients with chronic conditions. It was estimated that this could avoid a further 918,200 influenza cases, 332,000 GP visits, 16,300 hospitalisations and 6,300 deaths across the four countries, with older adults accounting for 52% of hospitalisations and 80% of deaths. An additional €84 million in direct medical costs and €79 million in absenteeism costs would be saved in total, with most economic benefits delivered in France. CONCLUSIONS: Older adults represent most vaccine-preventable influenza cases and deaths, followed by individuals with chronic conditions. Health authorities should prioritise vaccinating these populations for maximum public health and economic benefits.

State legislation and policies to improve perinatal mental health: a policy review and analysis of the state of Illinois.

Introduction: Maternal mental health problems, such as perinatal depression, are a major public health issue. In the U.S., several states have policies related to mental health during pregnancy and postpartum. The extent of these laws at the state level needs to be further explored and described. Methods: We systematically searched the Illinois General Assembly to determine all existing legislation on the topic of perinatal mental health. Results: This search uncovered two major Acts that 1) require universal perinatal depression screening and 2) raise awareness of the symptoms and treatment options related to maternal mental health. We also discovered provisions in the law that allow for untreated or undiagnosed postpartum depression or psychosis to be considered as a mitigating factor for women who commit forcible felonies. Discussion: Through legislation, states can lead change at the systems-level to improve perinatal mental health outcomes.

Cost-effectiveness of population-based screening for chronic obstructive pulmonary disease in China: a simulation modeling study.

Background: China has the highest disease burden of chronic obstructive pulmonary disease (COPD) in the world; however, the diagnosis rate remains low. Screening for COPD in the population may improve early diagnosis and long-term health outcomes for patients with COPD. In this study, we aimed to evaluate the cost-effectiveness of population-based COPD screening policies in China. Methods: We developed a microsimulation model that simulated incidence, natural history, and clinical management of COPD over a lifetime horizon among the general population aged 35-80 years in China. We evaluated population-based screening policies with different screening methods (one-step with COPD Screening Questionnaire or two-step with additional portable spirometer test) and frequencies (one-time or every 1-10 years). We calculated the incremental cost-effectiveness ratio (ICER) of the screening policies compared with the status quo (without screening) and identified the most cost-effective screening policy. Scenario and sensitivity analyses were performed to assess the impact of key parameters and the robustness of model results. Findings: Compared with the status quo, all population-based COPD screening policies were cost-effective with estimated ICERs ranging between $8034 and $13,209 per quality-adjusted-life-year (QALY), all under the willingness-to-pay value of $38,441/QALY (three times China's gross domestic product per capita). A total of 0.39%-8.10% of COPD-related deaths and 0.58%-2.70% of COPD exacerbations were projected to be averted by COPD screening. Among all screening policies, annual two-step screening was the most cost-effective. Improving the linkage from screening to diagnosis and treatment could further increase population health benefits and the cost-effectiveness of COPD screening. Interpretation: Population-based screening for COPD could be cost-effective in China. Offering public programs for COPD screening similar to existing preventive health services for other chronic diseases could be a promising strategy to improve population health outcomes and mitigate the disease burden of COPD in China.

An unintended consequence of COVID-19 immunity passports-quasi-experimental evidence of moral hazard observed after implementing the domestic Green Pass policy during the second wave of the COVID-19 pandemic in Italy.

Objectives: Amidst the second wave of the COVID-19 pandemic, Italian policymakers mandated to exhibit evidence of vaccination or immunity (the Green Pass) as a condition to access retail premises and public offices. This study aims to offer evidence, in a quasi-experimental setting, suggesting that an unintended consequence of this policy was the emergence of moral hazard. Methods: Google visit duration data measured the time customers typically spend on retail premises or public offices. A pairwise comparison of median visit time per premise was performed at a six-week interval before and after the introduction of the Green Pass. Results: This study is the first to provide evidence of "ex-post" moral hazard associated with introducing a domestic Green Pass policy. The median visiting time on premises that required digital immunity control significantly increased after introducing the domestic Green Pass policy, contrary to other public premises where access remained free of limitations. The increase in median visit time in premises with faster customer turnaround, such as coffee shops (+49%) and fast-food restaurants (+45%), was lower than the increase observed for fine-dining restaurants (+74%) and pizzerias (+163%). No significant increase in median visit time was observed in premises where the Green Pass was not required, such as food supermarkets, retail non-food shops, post offices, banks, pharmacies, and gas stations. Conclusion: The evidence of moral hazard highlights the critical issue of unintended consequences stemming from public health policies. This discovery is pivotal for policymakers, indicating that unforeseen behavioral adjustments could offset the intended benefits despite the intent to reduce risk through measures like the Green Pass.

Deciphering Trends in Cancer Mortality: A Comprehensive Analysis of Brazilian Data From 1979 to 2021 With Emphasis on Breast and Prostate Cancers.

Background: This study examined cancer mortality trends in Brazil from 1979 to 2021, emphasizing breast and prostate cancers. Methods: Utilizing data from the Brazilian Mortality Information System and the Brazilian Institute of Geography and Statistics, it analyzed cancer deaths nationally and regionally, highlighting gender-specific and regional disparities. Results: The research finds that cancer death rates have been growing at an average of 12% per year, contrasting with the population growth rate of 2.2%. This trend is more pronounced in the southern and southeastern regions of Brazil. A comparison of cancer mortality rates between Brazil, the USA, and China reveals that while the Brazilian and Chinese rates exhibit slower growth, the US rate shows a continuous decline since the 1990s. Conclusions: The study adopts a novel approach by focusing on growth rates and employing polynomial interpolation, revealing a deceleration in cancer death growth over the last 15 years across all malignant neoplasms. The study also contextualizes these findings within Brazil's cancer control policies, tracing the evolution of preventive measures and treatment advancements. It highlights the significant role of the National Cancer Institute and the Unified Health System in implementing effective strategies. The decreasing trend in cancer mortality rates in Brazil, despite population growth, illustrates the effectiveness of comprehensive cancer control and prevention measures, underlining their importance in public health policy.

Leveraging Policy Solutions for Diabetes Disparities: Suggestions for Improving the National Clinical Care Commission Report's Recommendations for Hispanic/Latino Populations.

In the U.S., Hispanic/Latino populations face increased disparities in both the prevalence and management of type 2 diabetes mellitus (T2DM). This article critically examines the multifaceted nature of T2DM disparities among Hispanic/Latino populations in the U.S. and identifies key factors contributing to T2DM prevalence within these communities, including socioeconomic status, cultural influences, and healthcare access. Utilizing a modified expert consensus procedure, we evaluate the ways in which the National Clinical Care Commission (NCCC) recommendations apply to the Hispanic/Latino community as well as propose recommendations for improved efficacy. Through a comprehensive analysis of government-community health initiatives, food security, environmental exposures, and housing inequalities, we emphasize the need for targeted interventions and health policies to effectively address and dismantle these disparities. Overall, while the National Clinical Care Commission's recommendations provide a valuable framework for the implementation of policies pertaining to diabetes management and prevention in the general population, our analysis suggests that recommendations may be strengthened by considering the unique cultural, social, and economic needs of the Hispanic/Latino population moving forward.

Advancing Evidence-Based Public Health Policy: How Core Component Thinking Can Illuminate the Multilevel Nature of Public Health Policy.

A growing body of literature uses the concept of core components to better understand small-scale programmatic interventions. Instead of interventions being viewed as unitary "black boxes," interventions are viewed as configurations of core components, which are the parts of interventions that carry their causal potential and therefore need to be reproduced with fidelity to produce the intended effect. To date, the concept of core components has not been as widely applied to public health policy interventions as it has to programmatic interventions. The purpose of this topical review is to familiarize public health practitioners and policy makers with the concept of core components as applied to public health policy interventions. Raising the profile of core component thinking can foster mindful adaptation and implementation of public health policy interventions while encouraging further research to enhance the supporting evidence base. We present 3 types of multilevel interactions in which the core components of a public health policy intervention produce effects at the population level by (1) seeking to directly affect individual behavior, (2) facilitating adoption of programmatic interventions by intermediaries, and (3) encouraging intermediaries to take action that can shape changes in upstream drivers of population health. Changing the unit of analysis from whole policies to core components can provide a basis for understanding how policies work and for facilitating novel evidence-generating strategies and rapid evidence reviews that can inform future adaptation efforts.

Health policy and regulations in Seychelles - barriers and opportunities for oral health inclusion.

BACKGROUND: Successful and inclusive policies that embrace oral health as part of the health agenda have the potential to alleviate the burden of oral diseases and to promote dental public health. This study aimed to understand the factors influencing the inclusion of oral health in health and public policy and regulations in the Seychelles. The barriers and opportunities for inclusion / non-inclusion as well as the impact thereof were explored. METHODOLOGY: A qualitative approach was adopted using document analysis and interviews as data collection strategies to allow for a complete analysis of the research problem. Using a purposive sampling approach, individual face to face interviews were conducted with patients, dental staff and representatives of the upper management. Policy and related oral health statistical documents were reviewed to ascertain how oral health was located and implemented from a national to a district level. Thematic analysis and content analysis were used to analyse and interpret the qualitative data. RESULTS: The study provided insight on how oral health is contextualised in the Seychelles and how public policy and strategic documents influences the oral health outcomes. There is fragmentation in how the health and oral health agendas are managed and it is coupled with a severe lack of involvement and commitment to address the latter. CONCLUSION: Oral health needs to be integrated in all relevant policies and public health programmes as part of the broader national NCDs in Seychelles in order reduce the incidence of oral diseases in the population.

Interactive network visualization of opioid crisis research: a tool for reinforcing data linkage skills for public health policy researchers.

Background: Public health policy researchers face a persistent challenge in identifying and integrating relevant data, particularly in the context of the U.S. opioid crisis, where a comprehensive approach is crucial. Purpose: To meet this new workforce demand health policy and health economics programs are increasingly introducing data analysis and data visualization skills. Such skills facilitate data integration and discovery by linking multiple resources. Common linking strategies include individual or aggregate level linking (e.g., patient identifiers) in primary clinical data and conceptual linking (e.g., healthcare workforce, state funding, burnout rates) in secondary data. Often, the combination of primary and secondary datasets is sought, requiring additional skills, for example, understanding metadata and constructing interlinkages. Methods: To help improve those skills, we developed a 2-step process using a scoping method to discover data and network visualization to interlink metadata. Results: We show how these new skills enable the discovery of relationships among data sources pertinent to public policy research related to the opioid overdose crisis and facilitate inquiry across heterogeneous data resources. In addition, our interactive network visualization introduces (1) a conceptual approach, drawing from recent systematic review studies and linked by the publications, and (2) an aggregate approach, constructed using publicly available datasets and linked through crosswalks. Conclusions: These novel metadata visualization techniques can be used as a teaching tool or a discovery method and can also be extended to other public policy domains.

The approach to developing Ireland's first national health protection strategy and lessons learnt, December 2021 to October 2022.

The COVID-19 pandemic highlighted the importance of strengthening health protection worldwide. To address this as a public health priority in Ireland, between December 2021 and October 2022 the first national Health Protection Strategy (2022-2027) for the Irish Health Service Executive (HSE) was developed. We describe the approach taken to develop a first national health protection strategy for Ireland, and highlight the key lessons learned. Key steps in strategy formation included detailed stakeholder analysis, exploration of the context for the strategy and development of a comprehensive consultation plan. Two stakeholder consultation workshops were held. The first focused on defining strategic vision, aim and objectives, the second verified objectives and identified enablers. A subsequent e-consultation invited feedback from wider stakeholders. The published strategy outlines 10 strategic objectives and 11 enablers. Key lessons identified from the strategy development process include the importance of clear leadership and oversight, the value of identifying the context for change, ensuring adequate consultation planning, taking a multidisciplinary approach with strong stakeholder engagement and the need to maintain a strategic perspective. Lessons from our experience can support colleagues internationally to strategically set out their priorities for health protection beyond COVID-19.

The role of religion and COVID-19 vaccine uptake in England.

BACKGROUND: While many countries have successfully deployed COVID-19 vaccination programmes, there are disparities in their uptake. One factor influencing vaccine coverage is religion. Existing research has found a link between religious beliefs and vaccine hesitancy. This study looks at religion in England to examine its relationship with public health. METHODS: This analysis used data from a survey of over 12,000 respondents in England, conducted through the YouGov Online Panel. Respondents were asked whether they identified with a religion, and if so which, and the number of COVID-19 vaccinations they had received. We employed logistic regressions to analyse the data, accounting for age, gender, education, generalised trust, trust in government, and political ideology. RESULTS: We find that respondents who identify as part of the Church of England have had significantly more COVID-19 vaccinations. Conversely, adherents to the Pentecostal Evangelical and Islamic faiths have had significantly fewer COVID-19 vaccinations. These relationships hold even when adjusting for age, education, level of trust, and political affiliation. CONCLUSION: This research indicates a potential influence of religious affiliation on vaccine uptake, highlighting the need for more carefully-tailored public health programmes. Recognizing the diverse associations of different religious affiliations on health behaviour is important for shaping future vaccination campaigns and policy interventions. Engaging with religious communities and leaders may be one method through which to deal with vaccine hesitancy and improve public health.

The U-Shaped Curve of Health Inequalities Over the 20th and 21st Centuries.

This article examines historical trends in health inequalities over the 20th and 21st centuries. Drawing on studies from the United States, United Kingdom, Sweden, and Western Europe, it concludes that there is evidence of a u-shaped curve in (relative) health inequalities. These trends in health inequalities broadly parallel those identified by economists with regards to the u-shaped curve of income and wealth inequalities across the 20th and 21st centuries. The article argues that-as with income inequalities-health inequalities generally decreased across the twentieth century through to the early 1980s. They then started to increase and accelerated further from 2010, particularly in the United Kingdom and the United States. The article sets out four distinct policy periods that shaped the evolution of trends in health inequalities: the Interbellum Era, 1920-1950; the Trente Glorieuse, 1950-1980; Neoliberalism, 1980-2010; and the Crisis Age, 2010-present. The u-shaped curve of health inequalities over this period suggests that social policies, health care access, and political incorporation have driven changes over time. Taking this long view of changes in health inequalities emphasizes the importance of politics and policy for future health improvement.

Correlation Between the Cost and Safety of Corneal Graft Types.

Background Corneal diseases are the fourth most common cause of blindness worldwide. In the majority of these diseases, vision reduction is reversible and can be restored to a large extent by replacing the cornea through specific surgery and, in particular, transplantation. In Greece, due to a lack of organized eye banks as well as donors, the grafts intended for corneal transplantation usually come from eye banks abroad. This study focuses on the dynamics of cost versus value in the decision-making process for the procurement of corneal grafts, ultimately investigating the safety that the procured grafts provide to patients. Methodology A total of 267 patients with severe vision problems who underwent 301 corneal and amniotic membrane transplants from years 2020 to 2023 at the Transplant Unit of the Athens General Hospital "Georgios Gennimatas" were included in this study. All patients who were deemed appropriate to undergo corneal transplant operations, the diagnosis that led to the specific surgery, and other relevant data were recorded and evaluated. Results There was no significant difference in the ratio between males and females (51.3% male and 48.7% female). The mean age of the patients was 66.5 years (SD = 13.7 years). Graft problems were faced by 13.9% of the patients, with the amniotic membrane by 1.5% (in the total number of surgical operations) and both eyes by 4.5% of patients. The majority of the patients had undergone only one surgery (88.8%). Reoperation was needed in 14% of the cases, and 7.6% of the cases were surgeries that occurred due to graft rejection or non-functioning grafts from surgeries performed at another hospital or clinic. In the majority of surgeries (60.8%), a Descemet's stripping automated endothelial keratoplasty graft was used. The mean cost was 3,167 euro (SD = 960.3 euro). Furthermore, in 35.8% of the surgeries, the graft was preserved with amphotericin. Conclusions The present study draws useful conclusions about the effectiveness of surgical interventions through the correlation of cost and safety of the grafts that are approved and finally used in corneal transplants, as well as the submission of proposals to improve the procedures and lead to patient benefits.

SARS-CoV-2 seroprevalence in Nova Scotia blood donors.

Background: SARS-CoV-2 seroprevalence monitors cumulative infection rates irrespective of case testing protocols. We aimed to describe Nova Scotia blood donor seroprevalence in relation to public health policy and reported data over the course of the COVID-19 pandemic (May 2020 to August 2022). Methods: Monthly random Nova Scotia blood donation samples (24,258 in total) were tested for SARS-CoV-2 infection antibodies (anti-nucleocapsid) from May 2020 to August 2022, and vaccination antibodies (anti-spike) from January 2021 to August 2022. Multivariable logistic regression for infection antibodies and vaccination antibodies separately with month, age, sex, and racialization identified independent predictors. The provincial nucleic acid amplification test (NAAT)-positive case rate over the pandemic was calculated from publicly available data. Results: Anti-N seroprevalence was 3.8% in January 2022, increasing to 50.8% in August 2022. The general population COVID-19 case rate was 3.5% in January 2022, increasing to 12.5% in August 2022. The percentage of NAAT-positive samples in public health laboratories increased from 1% in November 2021 to a peak of 30.7% in April 2022 with decreasing numbers of tests performed. Higher proportions of younger donors as well as Black, Indigenous, and racialized blood donors were more likely to have infection antibodies (p < 0.01). Vaccination antibodies increased to 100% over 2021, initially in older donors (60+ years), and followed by progressively younger age groups. Conclusions: SARS-CoV-2 infection rates were relatively low in Nova Scotia until the more contagious Omicron variant dominated, after which about half of Nova Scotia donors had been infected despite most adults being vaccinated (although severity was much lower in vaccinated individuals). Most COVID-19 cases were detected by NAAT until Omicron arrived. When NAAT testing priorities focused on high-risk individuals, infection rates were better reflected by seroprevalence.

Historique: La séroprévalence du SRAS-CoV-2 permet de surveiller les taux d'infection cumulatifs, quels que soient les protocoles de dépistage des cas. Les chercheurs voulaient décrire la séroprévalence chez les donneurs de sang néo-écossais par rapport aux politiques sanitaires et aux données déclarées tout au long de la pandémie de COVID-19 (mai 2020 à août 2022). Méthodologie: Les chercheurs ont mesuré les anticorps à l'infection par le SRAS-CoV-2 (antinucléocapsidiques) de manière aléatoire tous les mois dans des échantillons de dons de sang de la Nouvelle-Écosse (pour un total de 24 258) entre mai 2020 et août 2022, de même que les anticorps aux vaccins (antispiculaires) (entre janvier 2021 et août 2022). La régression logistique multivariable effectuée séparément pour les anticorps contre l'infection et les anticorps aux vaccins, par rapport au mois, à l'âge, au genre et à la race, ont permis d'établir les prédicteurs indépendants. Les chercheurs ont calculé le taux de cas provinciaux positifs aux tests d'amplification des acides nucléiques (TAAN) à partir des données publiques tout au long de la pandémie. Résultats: La séroprévalence anti-N, qui s'élevait à 3,8 % en janvier 2022, était passée à 50,8 % en août 2022. Le taux de cas de COVID-19 dans la population générale se situait à 3,5 % en janvier 2022 et était monté à 12,5 % en août 2022. Le pourcentage d'échantillons positifs au TAAN dans les laboratoires de santé publique est passé de 1 % en novembre 2021 à un pic de 30,7 % en avril 2022, conjointement à une diminution du nombre de tests effectués. De plus fortes proportions de donneurs plus jeunes et de donneurs noirs, autochtones et racisés étaient susceptibles de posséder des anticorps contre l'infection (p < 0,01). Les anticorps attribuables à la vaccination ont atteint 100 % en 2021, d'abord chez les donneurs plus âgés (de plus de 60 ans), puis dans les tranches d'âges progressivement plus jeunes. Conclusions: Les taux d'infection par le SRAS-CoV-2 sont demeurés relativement faibles en Nouvelle-Écosse jusqu'à la domination du variant Omicron plus contagieux, puis environ la moitié des donneurs néo-écossais ont été infectés, même si la plupart des adultes étaient vaccinés (la gravité de la maladie était toutefois beaucoup plus faible chez les personnes vaccinées). La plupart des cas de COVID-19 ont été dépistés par TAAN jusqu'à l'apparition du variant Omicron. Lorsque les priorités de dépistage par TAAN ont été limitées aux personnes à haut risque, les taux d'infection étaient mieux reflétés par la séroprévalence.

Pattern of Virtual Consultations in the Kingdom of Saudi Arabia: An Epidemiological Nationwide Study.

BACKGROUND: In the Kingdom of Saudi Arabia (KSA), little is known about the adoption of virtual consultations (VCs), with most studies being survey-based leading to varying results. This study aims to utilise secondary collected data on the use of both kinds of VCs currently available, and to epidemiologically describe the adoption of these consultations. METHODS: This retrospective study analysed data provided by the Ministry of Health between January 1st 2021 and June 30th 2022. For both the home-based and the hospital-based consultations, variables included the age and sex of patients, date of consultation, duration in minutes, closure status for the appointment and the governorate in which the patient is residing. A heat map was drawn to present patterns of utilisation across the country. RESULTS: The total number of VCs for both types were 1,008,228. For both types, females were higher adopters (54.73%). Of the total number of consultations, 751,156 were hospital-based. Of these consultations, family medicine consultations were the most common (20.42%), followed by internal medicine. Maternity follow-up clinics were higher in home-based clinics. The proportion of patient no-shows was high overall (48.30%). Utilisation was high in urban governorates, and low in rural ones. CONCLUSION: Findings have several implications on health policy. It provides further evidence of the importance of family medicine, where it was the most common speciality even in hospital-based settings. The high variability in the adoption of consultations across rural and urban areas as well as the extremely high number of patient-no-shows warrants further investigation.

The prevalence of developmental defects of enamel in people with cystic fibrosis: a systematic review.

BACKGROUND: Oral health impacts systemic health, individual well-being, and quality of life. It is important to identify conditions that may exacerbate oral disease to aid public health and policy development and promote targeted patient treatment strategies. Developmental defects can increase an individual's risk of dental caries, hypersensitivity, premature tooth wear, erosion, and poor aesthetics. As part of an ongoing study assessing oral health in adults with cystic fibrosis at Cork University Dental School and Hospital, a systematic review of available literature was conducted to assess the prevalence of enamel defects in people with cystic fibrosis. AIMS: To critically evaluate the literature to determine if the prevalence of developmental defects of enamel is higher in people with cystic fibrosis (PwCF). METHODS: Data Sources: Three online databases were searched Embase, Scopus, and Web of Science Core Collection. Studies that examined an association between cystic fibrosis and developmental defects of enamel were included in this systematic review. RESULTS: The initial search identified 116 publications from the following databases Embase, Web of Science Core Collection, and Scopus. Eleven studies were included for qualitative analysis. Nine studies concluded that PwCF had a higher prevalence of enamel defects than control people and one study found no difference in cystic fibrosis (CF) status. All studies had a risk of bias that may influence study results and their interpretation. CONCLUSIONS: The results of the systematic review show a consistent pattern that PwCF have a higher prevalence of DDE than people without CF. Genetic dysfunction, chronic systemic infections, and long-term antibiotic use are possible aetiological causes. This review highlights the need for future studies to investigate if DDEs are caused by the underlying CFTR mutation or as a consequence of disease manifestations and/or management.

Taxing sugar-sweetened beverages: Knowledge, beliefs and where should the money go?

Background: The Sugar-Sweetened Beverage (SSB) industry consciously and subconsciously influences consumers to buy its products. Countering unhealthy messaging and behaviour could be tackled through the SSB levy and allocation of revenue toward healthy lifestyle programs. Given the limited information in the UAE on demographic and consumer knowledge and beliefs and allocation of SSB levy, we conducted a study to explore this further. The study objectives were to a) explore the association between demographic factors (nationality, income and education) with knowledge and beliefs for SSB and b) explore participants' views on allocating SSB levy toward healthy lifestyle programs. Methods: A cross-sectional study of adults in the United Arab Emirates. Results: The findings suggest knowledge was high for Sugar-Sweetened Beverages (SSB), obesity, and diabetes (1,231, 96.1%), and there was a high awareness of SSB tax (1,066, 83.2%). Knowledge and beliefs about Sugar-Sweetened Beverages were statistically significant for two demographic factors. There was support for the tax revenue to be spent on government programs and greater support for spending to be directed toward specific healthy lifestyle programs such as school health programmes (514, 39.8%), children's diet and nutrition programmes (497, 38.5%), physical activity programmes (480, 37.2%), among others. Conclusions: The findings shed light on the influence demographic factors have on knowledge and beliefs, public health gaps and potential areas for SSB levy expenditure. Further research is needed to understand how best to implement healthy lifestyle programs within the community to optimise coverage, cost-effectiveness, and health outcomes.

Researchers should no longer delay implementation of Pap screening in low and middle income countries pending research into novel screening approaches.

A study coordinated by Groesbeck Parham and Mark Schiffman describes a novel approach to single-visit, point-of-care cervical screening and triage for low and middle income countries (LMICs) that uses an HPV screening test that is not affordable in LMICs combined with a triage test that is not available at the point of care. Pap smears are feasible, affordable, and well-suited for single-visit, point-of-care cervical screening and triage in LMICs. Research into a discredited cervical screening test, funded by the US National Cancer Institute, contributed to at least 500,000 preventable cervical cancer deaths by delaying implementation of Pap screening throughout India for 18 years. Researchers should no longer delay implementation of Pap screening in LMICs pending research into novel screening approaches. Instead, researchers should prioritize cervical screening approaches that will save as many lives as quickly as possible in LMICs. To that end, Parham et al. should implement good-quality, single-visit, point-of-care Pap smear screening in LMICs until better-quality, single-visit, point-of-care HPV screening becomes widely affordable in LMICs.

Assessment of Human Health Impacts from Invasive Pufferfish (Attacks, Poisonings and Fatalities) across the Eastern Mediterranean.

The silver-cheeked toadfish Lagocephalus sceleratus (Gmelin 1789), and to a lesser degree the orange spotted toadfish Torquigener hypselogeneion (Bleeker, 1852), pose threats to human health from physical attacks and poisonings in the Eastern Mediterranean Sea. This study reviewed human health-related impacts resulting from these pufferfish, compiling and assessing records from online sources, the peer-reviewed literature, medical records, personal interviews, and observations across the Eastern Mediterranean in the years 2004 to 2023. A total of 198 events impacting human health were documented: 28 records of physical attacks, at least 144 non-lethal poisoning episodes, and 27 human fatalities resulting from consumption. The majority of the reported incidences occurred in Syria, Türkiye, and Lebanon. Most physical attacks occurred in summer, while most poisoning events occurred during winter. The number of recorded incidents greatly increased after 2019, especially with regard to poisonings, yet whether this is related to greater media attention, or to increased fish abundance is unclear. This is the first comprehensive study to collate findings on attacks, poisonings and fatalities caused by these pufferfish in the Mediterranean Sea, and may help in improving national health policies. We urge the continuation of national campaigns to caution residents and tourists of these species' high toxicities and potential aggressiveness.
