Multiple Acquisitions of XopJ2 Effectors in Populations of Xanthomonas perforans.

Type III effectors (T3Es) are major determinants of Xanthomonas virulence and targets for resistance breeding. XopJ2 (synonym AvrBsT) is a highly conserved YopJ-family T3E acquired by X. perforans, the pathogen responsible for bacterial spot disease of tomato. In this study, we characterized a new variant (XopJ2b) of XopJ2, which is predicted to have a similar three-dimensional (3D) structure as the canonical XopJ2 (XopJ2a) despite sharing only 70% sequence identity. XopJ2b carries an acetyltransferase domain and the critical residues required for its activity, and the positions of these residues are predicted to be conserved in the 3D structure of the proteins. We demonstrated that XopJ2b is a functional T3E and triggers a hypersensitive response (HR) when translocated into pepper cells. Like XopJ2a, XopJ2b triggers HR in Arabidopsis that is suppressed by the deacetylase, SOBER1. We found xopJ2b in genome sequences of X. euvesicatoria, X. citri, X. guizotiae, and X. vasicola strains, suggesting widespread horizontal transfer. In X. perforans, xopJ2b was present in strains collected in North America, Africa, Asia, Australia, and Europe, whereas xopJ2a had a narrower geographic distribution. This study expands the Xanthomonas T3E repertoire, demonstrates functional conservation in T3E evolution, and further supports the importance of XopJ2 in X. perforans fitness on tomato.

Digital Health Literacy Enhancement Strategies Across Diverse Groups: A Scoping Review

Abstract Background The COVID-19 pandemic has accelerated the use of digital health technologies. Digital health literacy (DHL) is essential for effectively understanding and applying electronic health information. However, unequal access and use of these technologies require interventions to improve DHL for fair healthcare access. Objectives This scoping review aimed to identify strategies to enhance DHL in patients and the general population. Methods The review used the Joanna Briggs Institute Scoping Review Methodology and PRISMA-ScR guidelines. Eligibility criteria included a wide population, interventions aimed at improving DHL, with no restrictions on outcomes. The search strategy included electronic databases (MEDLINE, PsycINFO, Web of Science), and AI-based software, AS Review, was used for screening. Results The review found 5149 articles, 44 met the eligibility criteria. Studies focused on different demographic groups and health conditions. Most interventions were in North America and Europe. The study designs varied. Interventions via mobile apps, online platforms, and in-person sessions aimed at various conditions yielded positive results, including increases in DHL, self-management skills, and health-related behaviors. These interventions involved either independent interventions that focused on DHL or integrated interventions that were part of another intervention that aimed at a health outcome and had an element of DHL enhancement. Conclusions The review highlights the importance of DHL in informed decision-making and navigating digital health environments. While many interventions had positive outcomes, methodological limitations challenge the findings, emphasizing the need for more rigorous study designs. Future research should address sustainability, scalability, and the impact of DHL on health disparities, considering cultural sensitivity when developing interventions. Key messages • Scoping review identifies strategies to enhance Digital Health Literacy (DHL), crucial for effective use of health technology. • Despite positive outcomes, methodological limitations exist. Future research should focus on sustainability and scalability.

LANDSLIDE DETECTION AND MONITORING TECHNIQUES: A BIBLIOMETRIC ANALYSIS AND FUTURE DIRECTIONS

The devastating consequences of landslides demand rigorous assessment and effective management strategies to minimise risks. In this context, landslide detection and monitoring are crucial in identifying potential hazards and implementing proactive mitigation measures. This study uses the Scopus database to present a bibliometric analysis of 1,112 peer-reviewed journal articles on landslide detection and monitoring techniques published between 2002 and 2022. The analysis reveals a remarkable surge in publications, from 4 in 2002 to 180 in 2022, with the last five years (2018-2022) accounting for over 60% of the total publications. Over 3,259 unique researchers from 75 countries contributed to this field, with a significant portion originating from Asia, Europe, and North America. China and Italy emerged as the leading countries, producing over half of the articles. Nicola Casagli, from Italy, authored the most publications and garnered the highest number of citations. Remote Sensing emerged as the most preferred journal for authors, while Landslides garnered the highest total citations, and Geomorphology has the most normalised citations per article. The Chinese Academy of Sciences, China University of Geosciences, and the University of Florence in Italy were the most productive research institutions. The Natural Science Foundation of China (NSFC) emerged as the top funding agency. “Landslide”, “landslide monitoring”, and “early warning systems” were the top three most frequently used keywords. Keyword analysis identified landslide detection and monitoring advancements in remote sensing, analytical methods, and in-situ techniques. Co-occurrence analysis of trending research terms highlighted three distinct thematic clusters: remotely sensed data with machine learning and image analysis for landslide detection, field instrumentation for continuous deformation monitoring, and development of early warning systems for landslide hazard assessment and mitigation.

Non-Chemical Control of Nymphal Longhorned Tick, Haemaphysalis longicornis Neumann 1901 (Acari: Ixodidae), Using Diatomaceous Earth

The longhorned tick (LHT), Haemaphysalis longicornis Neumann (Acari: Ixodidae), is a serious invasive pest in North America where its geographical range is expanding with high densities associated with commercial animal production. There are only a few chemical pesticides available for LHT control, which can lead to the evolution of resistant strains. Diatomaceous earth (DE) was shown to be effective in killing some important tick species but was not examined for LHTs. When LHT nymphs were dipped for about 2–4 s into DE, transferred to Petri dishes (one tick/dish), and incubated at 30 °C and 70% relative humidity, the median survival time was 4.5 h. A locomotor activity assay showed that there was no difference in the overall distance traveled between the DE-treated and control ticks except during the first 2 h after exposure. In a field-simulated study in which a dose of 5.0 g DE/m2 was applied to pine needle litter infested with LHT, all the LHTs were dead at 24 h with no control mortality. Scanning electron micrographs showed the mineral adhering to all surfaces of the tick. The results indicated that DE is effective in killing nymphal LHTs and could be an alternative to the use of chemical acaricides with the advantage of managing pesticide resistance through the killing by a different mode of action and could be used for organically certified animal husbandry.

Indicators of the clinical utility of genetic or genomic testing: a scoping review

Abstract Background Genetic or genomic tests are the cornerstones of personalized prevention. Previous reviews primarily focused on theoretical frameworks rather than actual assessments and assessed dimensions rather than specific indicators within these dimensions. Our scoping review aimed to review the dimensions and the specific indicators measured in the published assessment reports of genetic or genomic tests. Methods We selected formal assessments of genetic and genomic test used for prevention through PubMed, Web of Science, Scopus, websites of 20 different organizations, Google, and Google Scholar. Also, through a separate analysis we identified ten comprehensive dimensions of clinical utility through an analysis of 30 theoretical frameworks for genetic and genomic tests. From the included assessments, we extracted all the indicators, clustering them based on the comprehensive dimensions. Results From 3054 unique references and 12000 grey literature search results, we collected 57 assessments, all from high income-countries (in Europe (53%) and North America (47%)). The assessment methods were HTA (42%), EGAPP (25%), ACCE (21%) and other (12%). 951 disease-specific indicators were extracted from the assessments. Analytic validity (60%), clinical validity (79%) clinical efficacy (79%), economic impact (58%) were the most common dimensions (had at least one indicator). However, only 12 assessments (21%) include indicators that compared health outcomes between tested and untested groups. Equity, acceptability, legitimacy, and personal value were evaluated in less than 15% of the documents. Conclusions Our study illustrate that, although dimensions such as equity and acceptability, are significantly emphasized in traditional evaluation frameworks, these are often not considered in the assessments. Additionally, our study has underscored a significant dearth of primary evidence concerning the clinical efficacy of these technologies. Key messages • Our study highlights the prevalence of evaluations lacking indicators for equity, acceptability, and legitimacy dimensions and a lack of direct evidence of clinical efficacy. • The catalog of indicators was openly provided as a resource for researchers and institutions working in evidence-based evaluations of personalized preventive healthcare.

Clinical outcomes in patients with unintended pregnancy after liver transplantation: A multicenter registry cohort study.

The consequences of unintended pregnancy in liver transplant (LT) recipients, a growing part of the high-risk obstetric population, remain unknown. To fill this gap, we conducted a retrospective registry cohort study to describe the risk factors, obstetric and neonatal morbidity, and graft outcomes associated with unintended pregnancy after LT. This study utilized the Transplant Pregnancy Registry International (TPRI) and included 565 pregnancies of LT recipients between 1967 and 2019 from 289 hospitals, primarily in North America. The primary outcome of acute cellular rejection (ACR) and secondary outcomes of graft loss, severe maternal morbidity, and neonatal composite morbidity were compared by pregnancy intention. The study population included 60.9% with intended pregnancies and 39.1% unintended pregnancies. Recipients with unintended pregnancy were more likely to self-report as Black race, to be younger, nulliparous, and have exposure to teratogenic immunosuppression. ACR was more common with unintended pregnancy (3.7% vs 1.2%, p=0.047). Unintended pregnancies had lower median birth weight (2806.6 vs 2948.4 grams, p=0.033). Unintended pregnancy was not associated with increased neonatal morbidity or severe maternal morbidity. These findings underscore the importance of family planning counseling, access to safe and effective contraceptive options, as well as multidisciplinary prenatal care in the growing population of reproductive-aged LT recipients.

Fluoride exposure and risk of fractures: a systematic review and dose-response meta-analysis

Abstract Introduction Fluoride (F) is a widespread natural element, whose exposure occurs mostly through drinking water, fluoridated foods and use of toothpastes. At high levels, it may adversely affect human health by altering thyroid and cognitive function in children, and inducing dental and skeletal fluorosis. Since bone health significantly impacts quality of life, we performed a systematic review and meta-analysis to evaluate the effect of F exposure on risk of bone fractures. Methods We conducted a literature search in online databases and selected studies that were carried out in humans and reported risk estimates with 95% confidence intervals for bone fractures according to F exposure. We eventually performed a meta-analysis using a random effects model, comparing the highest versus the lowest exposure, and one-stage dose-response model, to explore the shape of the association. Results Of the 1052 potentially eligible articles, 28 were included in the quantitative analyses. Most studies were conducted in adults (n = 26) and in Western countries (North America=16, Europe=11) and assessed fluoride exposure in drinking water, urine, serum, toenail or diet. The preliminary dose-response curve showed a positive non-linear relation between F exposure through drinking water and bone fracture risk, regardless of site, starting at 1.5 mg/L. Sex-stratified analyses, based on a lower number of studies, showed similar trends, with an indication of higher susceptibility in males compared with females. Conclusions Overall, risk of bone fractures appears to non-linearly increase along with exposure to fluoride in drinking water, regardless of bone site and sex, at levels of exposure above the WHO standard and similar to those that have associated to altered thyroid and cognitive function. Under a public health perspective, fluoride in drinking water should be kept below 1.5 mg/L to prevent bone fractures. Key messages • Our analysis revealed a positive non-linear association between fluoride in drinking water and bone fracture risk. • Public Health actions should be oriented in keeping fluoride in drinking water below 1.5 mg/L to prevent bone fractures.

Mapping and evaluating spatiotemporal patterns of urban expansion in global earthquake-affected areas: a nighttime light remote sensing perspective

ABSTRACT Amidst the backdrop of frequent global earthquakes, assessing the spatiotemporal dynamics of urban expansion in earthquake-affected areas is imperative for sustainable development insights. The current analyses, however, are primarily focused on administrative units or some specific natural units. Here, we quantified spatiotemporal patterns of urban expansion from 2000 to 2020 in global earthquake-affected areas globally. Specifically, we delineated such areas using data from earthquakes of magnitude 5.5 and above since 1965. Then, employing nighttime light remote sensing data, we extracted urban entities and systematically evaluated the spatiotemporal patterns of urban expansion in earthquake-affected areas. The findings indicate a phase-based differential growth in urban expansion in earthquake-affected areas from 2000 to 2020. The average deceleration factor for urban areas in earthquake-affected areas over the past 20 years is 128.67%. Urban expansion in earthquake-affected areas is growing at a rapid pace, except for Europe and North America. In addition, 66.7% of urban expansion in global earthquake-affected areas presents low-density sprawl and solitary edge expansion trends, potentially affecting population density and land use efficiency. This study offers the most exhaustive analysis of urban expansion in earthquake-affected areas in recent decades and calls for administration beyond administrative boundaries to some extent.

Stakeholder perspectives on supplemental milk for infants under six months with growth faltering

Abstract Background Growth faltering is a significant public health issue among infants aged <6 months (m). Supplemental milk is commonly used for infants with growth faltering, with variations in type and duration. We synthesized qualitative evidence on stakeholder perspectives about equity, feasibility, and acceptability of the type and duration of supplemental milk for infants aged <6m with growth faltering. Methods We conducted a comprehensive search of six electronic databases in addition to manual searches to identify all qualitative studies published during January 2000-June 2022. Identified articles were screened in two stages against an inclusion criteria with titles and abstract screened first followed by full-text screening. Included studies were quality appraised using the Critical Appraisal Skills Programme checklist. The primary outcome was equity, feasibility, and acceptability of various supplemental milk for infants <6mwith growth faltering. Results Eighteen studies, reporting perspectives of mothers, fathers, grandmothers and healthcare providers were included. Studies were conducted in North America (9), Africa (5) and Asia (3) and South Australia (1). Donor human milk (DHM) (13) and infant formula(9) were the main supplementary milk reported followed by cow/goat milk (2). Key sub-themes derived were: education/awareness, socio-economic status (SES), race and religion, practicality, availability of resources, sustainability, cost, affective attitude, perceived effectiveness and ethicality. Maternal/caregiver SES was a key sub-theme across all three supplemental milk feeds, acting either as a barrier or facilitator for uptake. Conclusions DHM and infant formula were the most commonly reported supplemental feed for infants aged <6m with growth faltering. Maternal/care giver factors were perceived as key to ensure equity, feasibility, and acceptability with respect to type and duration of supplemental milk for infants aged <6m with growth faltering. Key messages • Stakeholders perceived donor human milk and infant formula as main supplemental milk for infants aged <6 months with growth faltering. • Maternal/care giver factors are key to ensure equity, feasibility, and acceptability of supplemental milk for infants aged <6 months with growth faltering.

National early warning systems for emerging AMR in high-income countries: a systematic review

Abstract Background An urgent need of implementing national surveillance systems for timely detection and reporting of emerging antimicrobial resistance (AMR) was recently advocated by the World Health Organization (WHO). However, public information on existing national early warning systems (EWSs) is often incomplete. Furthermore, when findings are available, understanding these systems is challenging due to different approaches used for data collection, reporting and definitions, with a comprehensive overview on this topic currently lacking. The aim of this study was to map existing EWSs for emerging AMR, focusing on high-income countries, and describe their main characteristics. Methods A systematic review was performed on bibliographic databases, and a targeted search was conducted on national websites. Any article, report or webpage describing national EWSs in high-income countries was eligible for inclusion. EWSs were identified considering the emerging AMR reporting WHO framework. Results We identified seven national EWSs in 72 high-income countries: two (Australia, Japan) in the East Asia and Pacific Region, three (France, Sweden, United Kingdom) in Europe and Central Asia, and two (United States, Canada) in North America. The systems were established quite recently; in most cases they covered both community and hospital settings, but their main characteristics varied widely across countries in terms of organization and microorganisms under surveillance, with also different definitions of emerging AMR and alert functioning. A formal system assessment was available only in Australia. Conclusions A broader implementation and investment of national surveillance systems that allow early detection of emerging AMR is still needed to establish EWSs in countries and regions lacking such capabilities. A more standardized data collection and reporting is also advisable to improve cooperation on a global scale. Key messages • This study provides a synthesis of publicly available information on national EWSs for emerging AMR in high-income countries, highlighting the urgent need for a broader implementation of such systems. • Main characteristics of EWSs have been outlined, varying widely across countries. Findings could help stakeholders in strengthening current standard national AMR surveillance systems.

Economic evaluation of Polygenic Risk Scores in healthcare interventions: a systematic review

Abstract Background Polygenic Risk Scores (PRS) quantify genetic susceptibility to diseases, promising personalized healthcare. This review explores current evidence regarding the economic evaluation of strategies based on PRS or other polygenic risk stratification approaches, scrutinizing their methodologies. Methods The study protocol was registered in PROSPERO (CRD42023442780). A systematic search in PubMed, Scopus, and Web of Science identified full economic evaluations of intervention based on polygenic risk stratification strategies. The quality of the included articles was assessed using the Drummond checklist. This study was supported by the EC and MUR under PNRR - M4C2-I1.3 Project PE_00000019 ‘HEAL ITALIA”. Results Nineteen articles were included in the analysis, with oncological conditions being the most frequently investigated (13), followed by cardiovascular conditions (3). In nearly 80% of the studies, PRS was employed for screening interventions, with the general population being the primary target in 14 out of the 19 studies. All the economic analysis models investigated cost-utility in terms of QALYs, with Markov models and microsimulations being the most common structures. The majority of these models were based on simulated cohorts derived mostly from North American or European data, with 9 adopting a healthcare system perspective and 6 a societal perspective. Although delivery strategies for PRS testing were rarely addressed, PRS costs were included in nearly all studies. Indirect costs were examined in fewer than half of the studies. In 12 out of 19 studies, the conclusions claimed the cost utility of PRS involving strategies. Conclusions Despite the technique’s potential, evaluations of various strategies based on PRS approaches yield heterogeneous conclusions regarding cost-utility. Our study highlights the factors contributing to this heterogeneity and underscores the need for further exploration, ideally prioritizing real-world data. Key messages • PRS strategies evaluations vary in cost-utility conclusions, highlighting the need for further investigation. • Real-world data and practical implications should be prioritised in PRS research.

Association of race with incidence, characteristics, and mortality from incidental prostate cancer: Analysis of two North American contemporary cohorts.

Non-Hispanic Black (NHB) men are at higher risk both for incidence and mortality from prostate cancer (PCa) compared to Non-Hispanic White (NHW) men, but these findings arise from biopsy-detected PCa reports. We aimed to compare the incidence, subsequent management and cancer-specific mortality (CSM) of incidental PCa among NHB and NHW men, using two different North American cohorts. The Surveillance, Epidemiology and End-Result (SEER: 2004-2017) and our institutional Henry Ford Health (HFH: 1995-2022) databases were queried to identify men diagnosed with incidental PCa. Cumulative incidence estimates were used to calculate CSM differences between NHB and NHW men. Competing-risk multivariable regression analysis tested the impact of race on CSM, after accounting for all available covariates. A total of 418 and 6,124 incidental PCa cases were recorded in HFH and SEER database respectively. No pathological differences were observed between NHB and NHW men in both the cohorts, except for prostate-specific antigen (PSA) value at diagnosis, which was higher in NHB men. At 10-years, the CSM rates were 5.5% vs 7.2% in our cohort and 8.6% vs 10.3% in the SEER cohort for NHW and NHB men, respectively (all Gray's test p-value > 0.05). At multivariable, race was not an independent predictor of CSM in our HFH cohort (HR: 1.46, 95% CI: 0.57-3.71, p = 0.6). In the SEER cohort, NHB men were 34% less likely to die from PCa from 1 year to the next (95% CI: 0.49-0.90, p = 0.008), when compared with NHW men. In the comparison of incidental PCa findings between NHB and NHW men, both groups had similar pathological characteristic and survival outcomes. These findings are different from the 'conventional' screening-detected PCa and suggest that racial differences have minimal to no adverse effects on PCa-specific mortality after incidental diagnosis.

Update on surveillance guidelines in emerging Wilms tumor predisposition syndromes.

Wilms tumors are commonly associated with predisposition syndromes. Many of these syndromes are associated with specific phenotypic features and are discussed in the related paper from the AACR Pediatric Cancer Working Group. Guidelines for surveillance in this population were published in 2017 but since then several studies have identified new genes with recurrent pathogenic variants associated with increased risk for Wilms tumor development. In general, variants in these genes are less likely to be associated with other phenotypic features. Recently, members of the AACR Pediatric Cancer Working Group met to update surveillance guidelines for patients with a predisposition to Wilms tumors with a review of recently published evidence and risk estimates. Risk estimates for Wilms tumor for the more recently described genes are discussed here along with suggested surveillance guidelines for these populations. Several other emerging clinical scenarios associated with Wilms tumor predisposition are also discussed including patients with family histories of Wilms tumor and no identified causative gene, patients with bilateral tumors, and patients with somatic mosaicism for chromosome 11p15.5 alterations. This perspective serves to update pediatric oncologists, geneticists, radiologists, counselors and other healthcare professionals on emerging evidence and harmonize updated surveillance recommendations in the North American and Australian context for patients with emerging forms of Wilms tumor predisposition.

Quality of life measures with etripamil self-administration for acute episodes of paroxysmal supraventricular tachycardia in a medically unsupervised setting: patient-reported outcomes from NODE-303

Abstract Background Etripamil nasal spray (NS) is a fast-acting, self-administered calcium-channel blocker in development for the conversion of AV-nodal dependent paroxysmal supraventricular tachycardia (PSVT) in a medically unsupervised setting. Prior studies show favorable safety and efficacy in converting single episodes of PSVT to sinus rhythm (SR). Purpose In NODE-303, patient-reported outcome (PRO) instruments assessed quality of life (QoL) over multiple etripamil-treated episodes of PSVT. Methods NODE-303 was an event-driven, multi-center, open-label Phase 3 study in North and South American patients with documented PSVT that evaluated the safety and efficacy of etripamil in PSVT termination, over multiple episodes and without the need for prior test dosing. Enrolled patients who perceived PSVT symptoms applied an ambulatory ECG cardiac monitoring system (CMS), performed a pre-trained vagal maneuver and, if symptoms persisted, self-administered etripamil NS 70 mg. A study amendment allowed a repeat dose (etripamil NS, 70 mg) if symptoms persisted 10 min after the first dose. Each patient could self-treat up to 4 episodes. Safety was assessed through adverse events, clinical data, and ECG CMS recordings. The Treatment Satisfaction Questionnaire for Medication (TSQM; validated for acute episodic assessments) and other PROs were administered, and healthcare utilization data were acquired. Patients completed PROs at baseline (BL), monthly, and per PSVT episode, which collected information on symptoms, episode characteristics, rescue medications, and emergency room visits. Additional PROs were the Brief Illness Perception Questionnaire (BIPQ), Cardiac Anxiety Questionnaire (CAQ), and 36-Item Short Form Health Survey (SF-36). Results There were higher proportions of patients reporting mild, minimal or no disease severity, every 6 months, than at BL; extremely severe, severe, and moderate disease severity was reported by smaller proportions of patients than at BL, though incomplete surveys at later visits may limit this analysis. Anxiety and stress about future PSVT episodes were consistently reduced from BL. Measures of treatment satisfaction, effectiveness, and convenience were consistent across multiple episodes, and were at levels considered favorable for the TSQM instrument (Table 1). Rates of emergency-room visits and hospital admissions across multiple, treated PSVT episodes were similar to those observed in trials assessing single episodes (Table 2). The BIPQ, CAQ or SF-36 had no notable changes from BL. Conclusions Etripamil self-administration was associated with patient-reported improvements in degree of disease severity, decreased anxiety and stress over future PSVT episodes, and levels of treatment satisfaction, effectiveness, and convenience considered favorable for respective PRO instrument. Using a symptom-prompted, self-administered treatment for PSVT could potentially improve QoL measures and reduce healthcare resource utilization.

Nonstationarity in the global terrestrial water cycle and its interlinkages in the Anthropocene

Climate change and human activities alter the global freshwater cycle, causing nonstationary processes as its distribution shifting over time, yet a comprehensive understanding of these changes remains elusive. Here, we develop a remote sensing-informed terrestrial reanalysis and assess the nonstationarity of and interconnections among global water cycle components from 2003 to 2020. We highlight 20 hotspot regions where terrestrial water storage exhibits strong nonstationarity, impacting 35% of the global population and 45% of the area covered by irrigated agriculture. Emerging long-term trends dominate the most often (48.2%), followed by seasonal shifts (32.8%) and changes in extremes (19%). Notably, in mid-latitudes, this encompasses 34% of Asia and 27% of North America. The patterns of nonstationarity and their dominant types differ across other water cycle components, including precipitation, evapotranspiration, runoff, and gross primary production. These differences also manifest uniquely across hotspot regions, illustrating the intricate ways in which each component responds to climate change and human water management. Our findings emphasize the importance of considering nonstationarity when assessing water cycle information toward the development of strategies for sustainable water resource usage, enhancing resilience to extreme events, and effectively addressing other challenges associated with climate change.

Agroecological importance of smooth brome in managing wheat stem sawfly (Hymenoptera: Cephidae) via associated braconid parasitoids.

Wheat stem sawfly (WSS), Cephus cinctus Norton (Hymenoptera: Cephidae), is a major pest of cereal crops throughout the Northern Great Plains of North America. Native parasitoids, Bracon cephi (Gahan) and B. lissogaster Muesebeck (Hymenoptera: Braconidae), play a key role in suppressing WSS populations and limiting associated damage. Smooth brome grass (Bromus inermis Leyss.) serves as a potential trap reservoir for WSS when grown in areas surrounding wheat (Triticum aestivum L.) fields in Montana. Its unique biology allows it to support high WSS infestation while promoting significant larval mortality throughout the growing season. Late-season WSS survivors can then serve as hosts for WSS parasitoids. Our study investigated smooth brome as a host refuge for WSS parasitoids. We measured WSS larval infestation and survival rate inside smooth brome grown within WSS-inclusion cages, finding a maximum infestation of 66.5% and an end-of-year WSS survival of 5.7%. In addition, we collected stems from sites in central and north-central Montana to measure the WSS infestation and parasitoid prevalence in wheat and adjacent smooth brome. WSS infestation was high in both Big Sandy (64.5% smooth brome, 65.7% adjacent wheat) and Moccasin, MT (50.6%, 38.6%). Year-end WSS larval mortality was 43.6% greater in smooth brome compared to adjacent wheat at both field sites, but both hosted similar numbers of WSS parasitoids. This research underscores the importance of smooth brome in providing a sustainable host refuge for WSS parasitoids and highlights its significant role in supporting the economics of wheat cultivation.

Shifting cold regions streamflow regimes in North America affect flood frequency analysis

ABSTRACT Over threshold flood events in seventy years of data from 202 reference hydrometric stations in Canada and the United States were separated into nival, mixed, and pluvial flood types. While Mann-Kendall trend tests showed few significant trends in flood magnitude, significant changes in flood type fraction were found over time, with annual mean temperature, and with annual precipitation. Nival events decreased in frequency over the seventy-year period in 16% of sites, while mixed and pluvial events increased (5%, 12%). These changes indicate a shift from nival events towards more pluvial dominated systems. Fewer significant changes in flood type fraction were found with analysis against four climate indices. Flood frequency analysis using a combined distribution approach with the three flood types resulted in larger magnitude design flow estimates (median increase of 20 – 30 %) in comparison with the results from considering the data to be a single population.

Epidemiological profile and mortality of infective endocarditis over the past decade: a systematic review and meta-analysis of 133 studies comprising 132,355 cases

Abstract Background Understanding the epidemiology of infective endocarditis (IE) is crucial in the context of an aging population, increased comorbidities, and the heightened occurrence of healthcare-associated cases. Comprehensive data on causative agents, affected valves, and associated mortality are essential for current clinical practice. Methods This systematic review was conducted according to the PRISMA guidelines. A random effects model meta-analysis was conducted. Eligible studies reporting outcomes on IE were identified through a search of the PubMed/Medline database from 2010 to 2021. Results One hundred-thirty-three studies with 132,584 patients from six continents were included in the analysis. The most common causative agents of IE were Staphylococci species in 36% of cases, followed by Streptococci species in 26% of cases and Enterococci species in 10% of cases. Of the studies providing further speciation, the predominant species was Staphylococcus aureus with an incidence of 29%, followed by Viridans Streptococcus with an incidence of 12%. We found an in-hospital/30-day mortality of 17% (CI: 16%-19%) from 109 studies worldwide. In the subgroup analysis, the highest mortality rates were observed in Latin America 33% (CI: 28%-38%) and Africa 25% (CI: 21%-30%), while the lowest mortality rates were reported in Oceania 13% (CI: 8%-19%), followed by North America 14% (CI: 11%-18%), Asia 15% (CI: 12%-18%), and Europe 17% (CI: 16%-19%). The aortic valve was affected in 46% of cases, followed by the mitral valve in 43%. Tricuspid valve IE and multivalvular IE were identified in 7% and 14% of the cases, respectively. Conclusion Our study highlights the shift in epidemiological profile of IE over the last decade with S. aureus identified as the most common causative microorganism of IE in almost one third of cases. IE remains a highly morbid and fatal condition with high mortality rates even in tertiary and high-expertise centers worldwide. While left-sided IE is by far more common, right-sided IE and multivalvular IE are not rare entities and should be considered early in the differential of patients presenting with suspected IE to decrease the risk of future complications.Global burden of infective endocarditis.
