Estimating the Potential Public Health Value of BCG Revaccination.

An upcoming trial may provide further evidence that adolescent/adult-targeted BCG revaccination prevents sustained Mycobacterium tuberculosis infection, but its public health value depends on its impact on overall tuberculosis morbidity and mortality, which will remain unknown. Using previously calibrated models for India and South Africa, we simulated BCG revaccination assuming 45% prevention-of-infection efficacy, and we evaluated scenarios varying additional prevention-of-disease efficacy between +50% (reducing risk) and -50% (increasing risk). Given the assumed prevention-of-infection efficacy and range in prevention-of-disease efficacy, BCG revaccination may have a positive health impact and be cost-effective. This may be useful when considering future evaluations and implementation of adolescent/adult BCG revaccination.

The economic argument for hepatitis B treatment simplification and expansion.

One component of decisions regarding hepatitis B virus (HBV) treatment simplification and expansion is the economic perspective. Literature was reviewed for studies which provide estimates for the economic impact of simplifying and expanding treatment eligibility. Eight published studies and four unpublished studies were included and all but one subset of one study found that expanding treatment criteria would result in programs that would be at minimum cost-effective and most often highly cost-effective.

Time-dependent cost comparison and health economic impact analysis of second-line interventions for transplant-ineligible patients with relapsed or refractory diffuse large B cell lymphoma.

OBJECTIVES: Novel interventions (axicabtagene ciloleucel [axi-cel], lisocabtagene maraleucel [liso-cel], tafasitamab-lenalidomide [Tafa-L], polatuzumab-rituximab-bendamustine [pola-BR]) improve clinical outcomes in second-line (2 L) treatment of transplant-ineligible patients with early relapse or refractory (R/R) diffuse large B cell lymphoma (DLBCL). The costs vary depending on the respective treatment regimen and the treatment duration, difficult comparability in reimbursement decisions. The objective was to analyze the health economic impacts of novel 2 L interventions and conventional immunochemotherapies (bendamustine-rituximab [BR], rituximab-gemcitabine-oxaliplatin [R-GemOx]) from a German healthcare payer's perspective as a function of treatment duration. METHODS: An economic model was developed to compare treatment costs of 2 L interventions depending on the treatment duration. Treatment duration was measured by progression-free survival (PFS), identified based on a systematic review. Total and average costs were calculated over 5 years to evaluate incremental costs at median PFS for each intervention. RESULTS: Average costs per month at median PFS ranged from €2846 (95% CI: 5067-1641) to €40 535 (95% CI: 91180-N/A) for BR and liso-cel, respectively. Incremental costs at the lowest median PFS (R-GemOx: 5.3 months) revealed -€664, €5560, €11 817, €53 145, and €67 745 for BR, Tafa-L, pola-BR, axi-cel, and liso-cel as compared to R-GemOx, respectively. CONCLUSIONS: Analyses uncovered a variation of incremental costs of 2 L transplant-ineligible DLBCL interventions as a function of time leading to amortization of high-priced interventions.

Clinical and Economic Impact of CMV Infection in Allogeneic Hematopoietic Stem Cell Transplantation: Perspectives from a Middle-Income Nation.

BACKGROUND: Cytomegalovirus infection (CMV) is a common complication after allogeneic hematopoietic stem cell transplantation (AHSCT). CMV infection increases transplantation costs; however, the extent of the financial burden may vary in different countries. This study aims to determine the clinical and economic impact of CMV infection in patients undergoing AHSCT in a middle-income country. METHODS: A total of 150 adult and pediatric patients post-AHSCT were included for analysis. In addition to incidence of CMV infections, data on graft versus host disease (GVHD) were also collected. Standard hospital charges for AHSCT and any additional transplantation-related expenditure within 12 months were also retrieved in 104 patients. RESULTS: CMV infection, acute GVHD and chronic GVHD occurred in 38.7%, 60.7%, and 22.0% of patients, respectively. Patients with CMV infections had higher readmission rates compared to those who did not (67.2% vs. 47.8%; p = 0.020). Additional expenditure was seen in HLA-haploidentical AHSCT and CMV infection (MYR11 712.25/USD2 504.49; p < 0.0001 and MYR5 807.24/USD1 241.79; p = 0.036), respectively. CONCLUSION: This single-center study demonstrated that patients who underwent HLA-haploidentical AHSCT and subsequently developed CMV infection had higher transplantation expenditures compared to those who had matched-related transplantation. Further studies should be conducted to evaluate if primary prophylaxis against CMV is cost-effective, especially in patients who undergo HLA-haploidentical AHSCT.

New reimbursement models to promote better patient outcomes and overall value in laboratory medicine and healthcare.

The most widespread healthcare reimbursement models, including diagnostic laboratory services, are Fee-for-Service, Reference Pricing and Diagnosis-Related Groups. Within these models healthcare providers are remunerated for each specific service or procedure they operate. Healthcare payers are increasingly exploring alternative models, such as bundled payments or value-based reimbursement to encourage value of patient care rather than the simple amount of delivered services. These alternative models are advised, as they are more efficient in promoting cost-effective, high-quality laboratory testing, thereby improving patient health outcomes. If outcomes-based evaluation is a pillar in a new vision of "Value-Based Healthcare", an active policy of Value-Based Reimbursement in laboratory medicine will assure both an efficiency-based sustainability and a high-quality effectiveness-based diagnostic activity. This review aims to evaluate current and alternative reimbursement models, to support a wider agenda in encouraging more Value-Based Healthcare and Value-Based Reimbursement in laboratory medicine.

COVID-19 induced shocks and its implications for human capital development.

BACKGROUND: COVID-19 has delivered an enormous shock to the global economy, triggering the deepest recession in eight decades, almost three times as deep as the 2009 global recession. Of all the nations in Africa, Nigeria remains one of the nations with a huge and significant impact on the human capital. METHODS: Hence, here we employed the recent nationally representative data from Nigeria - the COVID-19 National Longitudinal Phone Survey 2020-World Bank Living Standards Measurement Study Integrated Agriculture Survey (LSMS-ISA), a harmonized dataset to explore how the COVID-19 induced shocks affected households' human capital development (using health and education outcomes). RESULTS: The results indicate that the COVID-19 induced shocks impact on both health and education in Nigeria. Interestingly, access to social safety nets had a positive association with the health and education outcomes. The study concludes that households' access to social safety nets, particularly during the COVID-19 pandemic aids in the development of the nation's human capital. Therefore, effectively enhancing household's resilience and strengthening human capital development require positive and considerable innovation, maybe over a period of years. Hence, just an access to the national social safety nets programs or social programs may not be as effective as expected. Therefore, it may not be as successful as intended to just have access to national social safety net programs or social programs that contribute or transfer negligible amounts to the vulnerable recipients over short time frames.

Non-pharmacological therapeutic needs in people with Dravet syndrome.

Dravet syndrome (DS) is a genetic rare disease, which is usually caused by a mutation in the SCN1A gene. DS is characterised by a drug-resistant epilepsy and by cognitive and behavioural disturbances. Thus, DS patients require both pharmacological and non-pharmacological treatments. However, there is a paucity of studies on non-pharmacological therapies and their potential benefits. The main aim of this study was to describe the non-pharmacological therapy modalities received by DS patients and their socio-economic impact on the family. Thus, we designed an online survey addressed to caregivers of DS patients. Our results indicated that up to 91.9% of the surveyed patients required non-pharmacological therapies, which were mainly directed to treat cognitive, sensory and motor impairments. In many cases, the economic costs of these therapies were borne entirely by the families. Nevertheless, patients required a deployment of resources not only at a health care level, but also at an educational level.

Nutritional, environmental and economic implications of children plate waste at school: a comparison between two Italian case studies.

OBJECTIVE: This study aims at comparing two Italian case studies in relation to schoolchildren's plate waste and its implications, in terms of nutritional loss, economic cost and carbon footprint. DESIGN: Plate waste was collected through an aggregate selective weighting method for 39 d. SETTING: Children from the first to the fifth grade from four primary schools, two in each case study (Parma and Lucca), were involved. RESULTS: With respect to the served food, in Parma, the plate waste percentage was lower than in Lucca (P < 0·001). Fruit and side dishes were highly wasted, mostly in Lucca (>50 %). The energy loss of the lunch meals accounted for 26 % (Parma) and 36 % (Lucca). Among nutrients, dietary fibre, folate and vitamin C, Ca and K were lost at most (26-45 %). Overall, after adjusting for plate waste data, most of the lunch menus fell below the national recommendations for energy (50 %, Parma; 79 %, Lucca) and nutrients, particularly for fat (85 %, Parma; 89 %, Lucca). Plate waste was responsible for 19 % (Parma) and 28 % (Lucca) of the carbon footprint associated with the food supplied by the catering service, with starchy food being the most important contributor (52 %, Parma; 47 %, Lucca). Overall, the average cost of plate waste was 1·8 €/kg (Parma) and 2·7 €/kg (Lucca), accounting respectively for 4 % and 10 % of the meal full price. CONCLUSION: A re-planning of the school meals service organisation and priorities is needed to decrease the inefficiency of the current system and reduce food waste and its negative consequences.

The economic burden of diseases in the Nordic countries: A systematic review.

BACKGROUND: Economic burden studies can provide insights into the drivers leading to increasing healthcare costs. It can also provide a more holistic view of how diseases impact the welfare of patients and their families. Having concrete estimates of the economic burden across multiple diseases can help policymakers determine which diseases are economically more burdensome. This study aimed to review and summarise comprehensively economic burden studies across multiple diseases in the Nordic countries between 2000 and 2020. METHODS: According to the 2020 PRISMA statement, a systematic literature review was conducted in PubMed, CINAHL, Academic Search Premier and Global Health databases using key terms related to the economic burden of any disease in Denmark, Finland, Greenland, Iceland, Norway and Sweden. Grey literature was also reviewed. RESULTS: A total of 10,050 potential titles and abstracts were identified and screened, and 254 full-text papers that met the inclusion criteria were evaluated by two independent reviewers. Of these, 119 articles were included in a qualitative synthesis. Twenty-nine had clearly defined comparison groups, thus able to attribute the costs to the disease. Large variations concerning methodology and cost components were noted. Across diseases, the economic burden ranged from EUR 1668 per patient annually for chronic obstructive pulmonary disease to EUR 93,041 for multiple sclerosis. However, estimates varied widely, even within each disease. CONCLUSIONS: Our review highlights the need for more comparable economic burden studies. Future studies should focus on applying robust methodology and homogeneous cost-reporting methods to inform policymakers about which diseases are economically more burdensome.

Clinical and economic burden of acute exacerbations of idiopathic pulmonary fibrosis: a prospective observational study in Spain (OASIS study).

BACKGROUND: Idiopathic pulmonary fibrosis (IPF) is a fatal progressive lung disease entailing significant impairment in health-related quality of life (HRQoL) and high socioeconomic burden. The course of IPF includes episodes of acute exacerbations (AE-IPF) leading to poor outcomes. This study aimed to compare management, costs and HRQoL of patients with AE-IPF to patients without AE-IPF during one year in Spain. MATERIALS AND METHODS: In a 12-month, prospective, observational, multicenter study of IPF patients, healthcare resource use was recorded and costs related to AE-IPF were estimated and compared between patients with and without AE-IPF. HRQoL was measured with the St. George's Respiratory Questionnaire (SGRQ), EuroQoL 5 dimensions 5 levels questionnaire (EQ-5D-5L), EQ-5D visual analogue scale (EQ-VAS) and the Barthel Index. RESULTS: 204 IPF patients were included: 22 (10.8%) experienced ≥ 1 acute exacerbation, and 182 (89.2%) did not. Patients with exacerbations required more primary care visits, nursing home visits, emergency visits, hospital admissions, pharmacological treatments and transport use (p < 0.05 for all comparisons). Likewise, patients with exacerbations showed higher annual direct health AE-IPF-related costs. In particular, specialized visits, emergency visits, days of hospitalization, tests, palliative care, transport in ambulance and economic aid (p < 0.05 for all comparisons). Exploratory results showed that patients with AE-IPF reported a non-significant but substantial decline of HRQoL compared with patients without AE-IPF, although causality can be inferred. CONCLUSION: We observed significantly higher resource use and cost consumption and lower HRQoL among patients suffering exacerbations during the study. Thus, preventing or avoiding AE-IPF is key in IPF management.

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.

Positive and negative aspects of the COVID-19 pandemic among a diverse sample of US adults: an exploratory mixed-methods analysis of online survey data.

BACKGROUND: The COVID-19 pandemic had a profound social and economic impact across the United States due to the lockdowns and consequent changes to everyday activities in social spaces. METHODS: The COVID-19's Unequal Racial Burden (CURB) survey was a nationally representative, online survey of 5,500 American Indian/Alaska Native, Asian, Black/African American, Latino (English- and Spanish-speaking), Native Hawaiian/Pacific Islander, White, and multiracial adults living in the U.S. For this analysis, we used data from the 1,931 participants who responded to the 6-month follow-up survey conducted between 8/16/2021-9/9/2021. As part of the follow-up survey, participants were asked "What was the worst thing about the pandemic that you experienced?" and "Was there anything positive in your life that resulted from the pandemic?" Verbatim responses were coded independently by two coders using open and axial coding techniques to identify salient themes, definitions of themes, and illustrative quotes, with reconciliation across coders. Chi-square tests were used to estimate the association between sociodemographics and salient themes. RESULTS: Commonly reported negative themes among participants reflected disrupted lifestyle/routine (27.4%), not seeing family and friends (9.8%), and negative economic impacts (10.0%). Positive themes included improved relationships (16.9%), improved financial situation (10.1%), and positive employment changes (9.8%). Differences in themes were seen across race-ethnicity, gender, and age; for example, adults ≥ 65 years old, compared to adults 18-64, were more likely to report disrupted routine/lifestyle (37.6% vs. 24.2%, p < 0.001) as a negative aspect of the pandemic, and Spanish-speaking Latino adults were much more likely to report improved relationships compared to other racial-ethnic groups (31.1% vs. 14.8-18.6%, p = 0.03). DISCUSSION: Positive and negative experiences during the COVID-19 pandemic varied widely and differed across race-ethnicity, gender, and age. Future public health interventions should work to mitigate negative social and economic impacts and facilitate posttraumatic growth associated with pandemics.

The Burden of Pelvic Pain Associated with Endometriosis among Women in Selected European Countries and the United States: A Restricted Systematic Review.

OBJECTIVE: To evaluate the burden of endometriosis-associated pelvic pain (EAPP) on health-related quality of life (HRQoL) among women living in similar socio-economic conditions. DATA SOURCES: Searches were performed in PubMed and Embase on September 26, 2022. The review was performed in conformity with the Preferred Reporting Items for Systematic Reviews and Meta-Analysis protocol (PRISMA-P) and was registered on PROSPERO (ID: CRD42023370363). METHODS OF STUDY SELECTION: Due to the high volume of eligible publications following initial review, inclusion criteria were restricted to studies undertaken in France, Germany, Italy, Spain, the United Kingdom, and the United States. This restriction was applied before screening as these countries have broad social and economic similarities, and previous studies in the literature suggest pain reporting and experience are influenced by numerous socio-cultural factors. Eligible studies were those published between 2013 and 2022 and include a sample size of ≥50 participants. The search strategy identified all relevant publications relating to the burden of illness due to EAPP. A variety of terms are used in the literature to describe pain associated with endometriosis, and this was considered in the design of the search strategy and screening procedure. TABULATION, INTEGRATION, AND RESULTS: The database searches resulted in a total of 6139 records. After removal of duplicates, 3855 records were assessed further. A total of 27 publications were identified as eligible. Fourteen (52%) were from Italy, 5 (19%) were multinational studies, 4 (15%) were from the United States, 3 (11%) were from Spain, and 1 (4%) was from Germany. Most studies were cross-sectional (n = 15; 56%); 7 (26%) were case-control studies; 3 (11%) were cohort studies; and 2 (7%) were longitudinal studies. These publications collectively highlighted an association between EAPP and reduced HRQoL. Several studies showed that EAPP was associated with lower HRQoL when compared with endometriosis without pain and potentially with chronic pelvic pain caused by other conditions, although the evidence is limited in this case. Moreover, the studies reported detrimental effects on general HRQoL, mental health functioning, and sexual functioning, culminating in reduced work productivity and difficulties in performing everyday activities. The associations were generally similar across study populations, including adolescents, as well as younger and older women. Results were consistent across the range of different patient-reported outcome tools used to assess HRQoL. CONCLUSION: The existing literature suggests that, among women in selected European countries and the United States, EAPP is associated with reduced HRQoL, including impaired mental and sexual functioning, as well as reduced work performance and productivity; each of which may contribute to the societal burden of endometriosis.

Manual versus automated chemotherapy preparation: A retrospective pharmaco-economic analysis.

INTRODUCTION: The National Oncology Institute of Morocco's (NIO) shift to an automated cytotoxic drug preparation system (PHARMODUCT®) has prompted an evaluation of its economic and clinical impacts compared to traditional manual methods. METHODS: A retrospective cost-benefit analysis over six months, extrapolated to annual projections, assessed initial investments, labour, equipment, drugs and consumables. Four commonly used chemotherapy drugs were analyzed, with a focus on the cost implications of drug waste in manual preparation versus the efficiency of vial-sharing in automated methods. RESULTS: The automated system incurred a higher initial cost $2,934,098.74, but reduced annual drug consumption costs by 19.74% and drug-related expenses by $41,228.27. It also decreased personnel costs by $48,073.35. Despite the upfront investment, the system is projected to break even within two years, with no medication waste due to its vial-sharing capability. CONCLUSION: The initial higher investment in pharmaceutical automation promises considerable long-term savings and efficiency gains. Despite the study's limited scope and duration, the findings endorse the adoption of automated systems in oncology pharmacy settings for sustainable financial management and improved clinical outcomes.

Expanding vaccination competencies to community pharmacists: modelling the organizational and economic impacts of new human papilloma virus (HPV) vaccine pathways in France.

BACKGROUND: The vaccine coverage rate (VCR) for human papillomavirus (HPV) in France is one of the lowest in Europe, well below the target of 80% announced in the French Cancer Plan 2021-2030. The extension of vaccination competencies (prescription and administration) to new health care providers, such as community pharmacists (CPs), was a decisive step by the French Health Authority (HAS) in 2022 to simplify access to vaccination and improve the VCR. This research assessed the economic and organizational impacts (OIs) of the extension of vaccination competencies in France. METHODS: A model was developed in Excel® to compare the current HPV vaccination pathway focused on general practitioners (GPs) to a mix of pathways (new and current) that extends pharmacists' competencies (prescription and/or injection). The simulated population corresponded to girls and boys targeted by the French recommendations. The model was run from 2023 to 2030. HAS guidelines were used to identify OIs related to these new pathways. Model inputs were collected from national data sources and an acceptability study. The results focused on three OIs (HPV vaccination ability [defined as the number of adolescents who could be vaccinated in each pathway], the VCR projection, and flows of activity between health care professionals]). The economic impact was evaluated from the National Health Insurance (NHI) perspective in 2022. RESULTS: With a mix of vaccination pathways, including an increasing role of pharmacists, the target of an 80% VCR could be reached in 2030 (versus 2032 with the current pathway) with lower investment than the current situation, resulting in cost savings for the NHI of €212 million. Expanding vaccination competencies will provide pharmacists with additional revenue (an average of €755,000/month for all vaccinating pharmacies) and will free up medical time for GPs (average of 603,000 consultations/year for all GPs). CONCLUSIONS: Expanding vaccination competencies to pharmacists has a positive impact on the entire ecosystem. From a public health perspective, the national VCR target can be achieved and better access to care can be provided, freeing up medical time. From an economic perspective, this approach can provide savings for the NHI and additional revenue for pharmacists.

The Economic Impact of Atopic Dermatitis.

Atopic dermatitis (AD) is a chronic inflammatory disorder that affects over 30 million people in the United States. Given the large and growing prevalence of AD, the associated economic burden is significant. It has been estimated that AD costs over $5 billion dollars annually. These costs include both direct and indirect costs. Direct costs include prescription medicines, visits to health-care providers, hospitalizations, and transportation. Indirect costs include missed days or lost productivity at work or school, career modification, and reduced quality of life. Understanding and measuring these costs can be accomplished through rigorous economic evaluation, which is the organized process of considering inputs and outcomes of various activities. Economic evaluation has been used to contextualize the burden of AD in society. It has also been used to inform patients, providers, and other stakeholders on how to deliver the most evidence-based, efficient way possible. Understanding the economic impact of atopic dermatitis is an important aspect of delivering high-quality care.

Wolves make roadways safer, generating large economic returns to predator conservation.

Recent studies uncover cascading ecological effects resulting from removing and reintroducing predators into a landscape, but little is known about effects on human lives and property. We quantify the effects of restoring wolf populations by evaluating their influence on deer-vehicle collisions (DVCs) in Wisconsin. We show that, for the average county, wolf entry reduced DVCs by 24%, yielding an economic benefit that is 63 times greater than the costs of verified wolf predation on livestock. Most of the reduction is due to a behavioral response of deer to wolves rather than through a deer population decline from wolf predation. This finding supports ecological research emphasizing the role of predators in creating a "landscape of fear." It suggests wolves control economic damages from overabundant deer in ways that human deer hunters cannot.

The economic and fiscal impact of incremental use of cell-based quadrivalent influenza vaccine for the prevention of seasonal influenza among healthcare workers in Italy.

BACKGROUND: Seasonal influenza has a significant impact on public health, generating substantial direct healthcare costs, production losses and fiscal effects. Understanding these consequences is crucial to effective decision-making and the development of preventive strategies. This study aimed to evaluate the economic and the fiscal impact of implementing an incremental strategy for seasonal influenza prevention using the cell-based quadrivalent influenza vaccine (QIVc) among healthcare workers (HCWs) in Italy. METHODS: To estimate the economic impact of implementing this strategy, we performed a cost analysis that considered direct healthcare costs, productivity losses and fiscal impact. The analysis considered a 3-year time horizon. A deterministic sensitivity analysis was also conducted. RESULTS: Assuming a vaccination coverage rate of 30% among HCWs, the analysis considered a total of 203 018 vaccinated subjects. On analysing the overall differential impact (including direct costs, indirect costs and fiscal impact), implementing QIVc vaccination as a preventative measure against influenza among HCWs in Italy would yield societal resource savings of €23 638.78 in the first year, €47 277.56 in the second year, and €70 916.35 in the third year, resulting in total resource savings of €141 832.69. CONCLUSIONS: The study demonstrated that implementing the incremental use of QIVc as part of a preventive strategy for seasonal influenza among HCWs in Italy could yield positive economic outcomes, especially in terms of indirect costs and fiscal impact. The resources saved could be utilized to fund further public health interventions. Policy-makers should consider these findings when making decisions regarding influenza prevention strategies targeting HCWs.

Effect of Fungicide and Timing of Application on Management of Phoma Black Stem of Cultivated Sunflowers in the United States.

Phoma black stem (PBS), caused by Phoma macdonaldii Boerema (teleomorph Leptosphaeria lindquistii Frezzi), is the most common stem disease of sunflower (Helianthus annuus L.) in the northern Great Plains region of the United States. However, the impact of PBS on sunflower yield in the United States is unclear, and a near complete absence of information on the impact of fungicides on disease management exists. The objectives of this study were to determine the impact of PBS on sunflower yield, the efficacy of available fungicides, the optimal fungicide application timing, and the economic viability of fungicides as a management tool. Fungicide timing efficacy was evaluated by applying single and/or sequential applications of pyraclostrobin fungicide at three sunflower growth stages in 10 field trials between 2017 and 2019. Efficacy of 10 fungicides from the Fungicide Resistance Action Committee (FRAC) groups 3, 7, and 11 were evaluated in four field trials between 2018 and 2019. The impact of treatments on PBS were evaluated by determination of incidence, severity, maximum lesion height, disease severity index (DSI), and harvested yield. Nine of the 10 fungicides evaluated and all fungicide timings that included an early bud application resulted in disease reductions when compared with the nontreated controls. The DSI was negatively correlated to sunflower yield in high-yield environments (P = 0.0004; R2 = 0.3425) but not in low- or moderate-yield environments. Although FRAC 7 fungicides were generally most efficacious, the sufficient efficacy and lower cost of FRAC 11 fungicides make them more economically viable in high-yielding environments at current market conditions.

Economic costs of non-native species in Türkiye: A first national synthesis.

Biological invasions are increasingly recognised as a major global change that erodes ecosystems, societal well-being, and economies. However, comprehensive analyses of their economic ramifications are missing for most national economies, despite rapidly escalating costs globally. Türkiye is highly vulnerable to biological invasions owing to its extensive transport network and trade connections as well as its unique transcontinental position at the interface of Europe and Asia. This study presents the first analysis of the reported economic costs caused by biological invasions in Türkiye. The InvaCost database which compiles invasive non-native species' monetary costs was used, complemented with cost searches specific to Türkiye, to describe the spatial and taxonomic attributes of costly invasive non-native species, the types of costs, and their temporal trends. The total economic cost attributed to invasive non-native species in Türkiye (from 202 cost reporting documents) amounted to US$ 4.1 billion from 1960 to 2022. However, cost data were only available for 87 out of 872 (10%) non-native species known for Türkiye. Costs were biased towards a few hyper-costly non-native taxa, such as jellyfish, stink bugs, and locusts. Among impacted sectors, agriculture bore the highest total cost, reaching US$ 2.85 billion, followed by the fishery sector with a total cost of US$ 1.20 billion. Management (i.e., control and eradication) costs were, against expectations, substantially higher than reported damage costs (US$ 2.89 billion vs. US$ 28.4 million). Yearly costs incurred by non-native species rose exponentially over time, reaching US$ 504 million per year in 2020-2022 and are predicted to increase further in the next 10 years. A large deficit of cost records compared to other countries was also shown, suggesting a larger monetary underestimate than is typically observed. These findings underscore the need for improved cost recording as well as preventative management strategies to reduce future post-invasion management costs and help inform decisions to manage the economic burdens posed by invasive non-native species. These insights further emphasise the crucial role of standardised data in accurately estimating the costs associated with invasive non-native species for prioritisation and communication purposes.
