Fusarium species,Scedosporium species, and Lomentospora prolificans: A systematic review to inform the World Health Organization priority list of fungal pathogens
Marinelli T , Kim HY , Halliday CL , Garnham K , Bupha-Intr O , Dao A , Morris AJ , Alastruey-Izquierdo A , Colombo A , Rickerts V , Perfect J , Denning DW , Nucci M , Hamers RL , Cassini A , Oladele R , Sorrell TC , Ramon-Pardo P , Fusire T , Chiller TM , Wahyuningsih R , Forastiero A , Al-Nuseirat A , Beyer P , Gigante V , Beardsley J , Sati H , Alffenaar JW , Morrissey CO . Med Mycol 2024 62 (6) Recognizing the growing global burden of fungal infections, the World Health Organization established a process to develop a priority list of fungal pathogens (FPPL). In this systematic review, we aimed to evaluate the epidemiology and impact of infections caused by Fusarium spp., Scedosporium spp., and Lomentospora prolificans to inform the first FPPL. PubMed and Web of Sciences databases were searched to identify studies published between January 1, 2011 and February 23, 2021, reporting on mortality, complications and sequelae, antifungal susceptibility, preventability, annual incidence, and trends. Overall, 20, 11, and 9 articles were included for Fusarium spp., Scedosporium spp., and L. prolificans, respectively. Mortality rates were high in those with invasive fusariosis, scedosporiosis, and lomentosporiosis (42.9%-66.7%, 42.4%-46.9%, and 50.0%-71.4%, respectively). Antifungal susceptibility data, based on small isolate numbers, showed high minimum inhibitory concentrations (MIC)/minimum effective concentrations for most currently available antifungal agents. The median/mode MIC for itraconazole and isavuconazole were ≥16 mg/l for all three pathogens. Based on limited data, these fungi are emerging. Invasive fusariosis increased from 0.08 cases/100 000 admissions to 0.22 cases/100 000 admissions over the time periods of 2000-2009 and 2010-2015, respectively, and in lung transplant recipients, Scedosporium spp. and L. prolificans were only detected from 2014 onwards. Global surveillance to better delineate antifungal susceptibility, risk factors, sequelae, and outcomes is required. |
WHO global antimicrobial resistance surveillance for Neisseria gonorrhoeae 201718: a retrospective observational study
Unemo M , Lahra MM , Escher M , Eremin S , Cole MJ , Galarza P , Ndowa F , Martin I , Dillon JAR , Galas M , Ramon-Pardo P , Weinstock H , Wi T . Lancet Microbe 2021 2 (11) e627-e636 Background: Gonorrhoea and antimicrobial resistance (AMR) in Neisseria gonorrhoeae are major health concerns globally. Increased global surveillance of gonococcal AMR is essential. We aimed to describe the 2017–18 data from WHO's global gonococcal AMR surveillance, and to discuss priorities essential for the effective management and control of gonorrhoea. Methods: We did a retrospective observational study of the AMR data of gonococcal isolates reported to WHO by 73 countries in 2017–18. WHO recommends that each country collects at least 100 gonococcal isolates per year, and that quantitative methods to determine the minimum inhibitory concentration of antimicrobials, interpreted by internationally standardised resistance breakpoints, are used. Findings: In 2017–18, 73 countries provided AMR data for one or more drug. Decreased susceptibility or resistance to ceftriaxone was reported by 21 (31%) of 68 reporting countries and to cefixime by 24 (47%) of 51 reporting countries. Resistance to azithromycin was reported by 51 (84%) of 61 reporting countries and to ciprofloxacin by all 70 (100%) reporting countries. The annual proportion of decreased susceptibility or resistance across countries was 0–21% to ceftriaxone and 0–22% to cefixime, and that of resistance was 0–60% to azithromycin and 0–100% to ciprofloxacin. The number of countries reporting gonococcal AMR and resistant isolates, and the number of examined isolates, have increased since 2015–16. Surveillance remains scarce in central America and the Caribbean and eastern Europe, and in the WHO African, Eastern Mediterranean, and South-East Asian regions. Interpretation: In many countries, ciprofloxacin resistance was exceedingly high, azithromycin resistance was increasing, and decreased susceptibility or resistance to ceftriaxone and cefixime continued to emerge. WHO's global surveillance of gonococcal AMR needs to expand internationally to provide imperative data for national and international management guidelines and public health policies. Improved prevention, early diagnosis, treatment of index patients and partners, enhanced surveillance (eg, infection, AMR, treatment failures, and antimicrobial use or misuse), and increased knowledge on antimicrobial selection, stewardship, and pharmacokinetics or pharmacodynamics are essential. The development of rapid, accurate, and affordable point-of-care gonococcal diagnostic tests, new antimicrobials, and gonococcal vaccines is imperative. Funding: None. © 2021 The Author(s).

The importance of binomial nomenclature for the identification of pollen aeroallergens
Ramon GD , Green BJ , Levetin E , Makra L , Bielory L . J Allergy Clin Immunol Pract 2021 9 (7) 2642-2644 The diagnosis and treatment of atopic disorders associated with specific aerobiological triggers require basic botanical training. However, the identification of specific pollen can often be confounded by broad naming conventions that range from categorized colloquial, to scientific names based on either higher taxonomic levels, or in some cases binomial nomenclature. Physicians specializing in allergy often lack a comprehensive understanding with respect to plant taxonomy and botanical nomenclature that are critical skills required for clinical practice and research programs evaluating pollen and airborne fungal spores. In addition, binomial and current family designation and synonyms, including author citation are often misused, causing a misinterpretation of existing plants species or pollen types. It is critical that the correct botanical name is linked to a validated specimen, and scientific naming conventions are used where possible by the clinician and researcher. In relation to pollen identification, we propose that clinicians and researchers should provide the currently accepted binomial nomenclature, offer relevant synonyms, and use the Angiosperm Phylogeny Group names. |
World Health Organization Global Gonococcal Antimicrobial Surveillance Program (WHO GASP): review of new data and evidence to inform international collaborative actions and research efforts
Unemo M , Lahra MM , Cole M , Galarza P , Ndowa F , Martin I , Dillon JR , Ramon-Pardo P , Bolan G , Wi T . Sex Health 2019 16 (5) 412-425 Antimicrobial resistance (AMR) in Neisseria gonorrhoeae is a serious public health problem, compromising the management and control of gonorrhoea globally. Resistance in N. gonorrhoeae to ceftriaxone, the last option for first-line empirical monotherapy of gonorrhoea, has been reported from many countries globally, and sporadic failures to cure especially pharyngeal gonorrhoea with ceftriaxone monotherapy and dual antimicrobial therapies (ceftriaxone plus azithromycin or doxycycline) have been confirmed in several countries. In 2018, the first gonococcal isolates with ceftriaxone resistance plus high-level azithromycin resistance were identified in England and Australia. The World Health Organization (WHO) Global Gonococcal Antimicrobial Surveillance Program (GASP) is essential to monitor AMR trends, identify emerging AMR and provide evidence for refinements of treatment guidelines and public health policy globally. Herein we describe the WHO GASP data from 67 countries in 2015-16, confirmed gonorrhoea treatment failures with ceftriaxone with or without azithromycin or doxycycline, and international collaborative actions and research efforts essential for the effective management and control of gonorrhoea. In most countries, resistance to ciprofloxacin is exceedingly high, azithromycin resistance is present and decreased susceptibility or resistance to ceftriaxone has emerged. Enhanced global collaborative actions are crucial for the control of gonorrhoea, including improved prevention, early diagnosis, treatment of index patient and partner (including test-of-cure), improved and expanded AMR surveillance (including surveillance of antimicrobial use and treatment failures), increased knowledge of correct antimicrobial use and the pharmacokinetics and pharmacodynamics of antimicrobials and effective drug regulations and prescription policies (including antimicrobial stewardship). Ultimately, rapid, accurate and affordable point-of-care diagnostic tests (ideally also predicting AMR and/or susceptibility), new therapeutic antimicrobials and, the only sustainable solution, gonococcal vaccine(s) are imperative. |

Early childhood education to promote health equity: A Community Guide economic review
Ramon I , Chattopadhyay SK , Barnett WS , Hahn RA . J Public Health Manag Pract 2017 24 (1) e8-e15 CONTEXT: A recent Community Guide systematic review found that early childhood education (ECE) programs improve educational, social, and health-related outcomes and advance health equity because many are designed to increase enrollment for high-risk children. This follow-up economic review examines how the economic benefits of center-based ECE programs compare with their costs. EVIDENCE ACQUISITION: Kay and Pennucci from the Washington State Institute for Public Policy, whose meta-analysis formed the basis of the Community Guide effectiveness review, conducted a benefit-cost analysis of ECE programs for low-income children in Washington State. We performed an electronic database search using both effectiveness and economic key words to identify additional cost-benefit studies published through May 2015. Kay and Pennucci also provided us with national-level benefit-cost estimates for state and district and federal Head Start programs. EVIDENCE SYNTHESIS: The median benefit-to-cost ratio from 11 estimates of earnings gains, the major benefit driver for 3 types of ECE programs (ie, state and district, federal Head Start, and model programs), was 3.39:1 (interquartile interval [IQI] = 2.48-4.39). The overall median benefit-to-cost ratio from 7 estimates of total benefits, based on all benefit components including earnings gains, was 4.19:1 (IQI = 2.62-8.60), indicating that for every dollar invested in the program, there was a return of $4.19 in total benefits. CONCLUSIONS: ECE programs promote both equity and economic efficiency. Evidence indicates there is positive social return on investment in ECE irrespective of the type of ECE program. The adoption of a societal perspective is crucial to understand all costs and benefits of ECE programs regardless of who pays for the costs or receives the benefits. |
Epidemiology of chikungunya in the Americas
Yactayo S , Staples JE , Millot V , Cibrelus L , Ramon-Pardo P . J Infect Dis 2016 214 S441-s445 Chikungunya virus (CHIKV) emerged in the Americas in late 2013 to cause substantial acute and chronic morbidity. About 1.1 million cases of chikungunya were reported within a year, including severe cases and deaths. The burden of chikungunya is unclear owing to inadequate disease surveillance and underdiagnosis. Virus evolution, globalization, and climate change may further CHIKV spread. No approved vaccine or antiviral therapeutics exist. Early detection and appropriate management could reduce the burden of severe atypical and chronic arthritic disease. Improved surveillance and risk assessment are needed to mitigate the impact of chikungunya. |
A Bacillus anthracis Genome Sequence from the Sverdlovsk 1979 Autopsy Specimens.
Sahl JW , Pearson T , Okinaka R , Schupp JM , Gillece JD , Heaton H , Birdsell D , Hepp C , Fofanov V , Noseda R , Fasanella A , Hoffmaster A , Wagner DM , Keim P . mBio 2016 7 (5) ![]() Anthrax is a zoonotic disease that occurs naturally in wild and domestic animals but has been used by both state-sponsored programs and terrorists as a biological weapon. A Soviet industrial production facility in Sverdlovsk, USSR, proved deficient in 1979 when a plume of spores was accidentally released and resulted in one of the largest known human anthrax outbreaks. In order to understand this outbreak and others, we generated a Bacillus anthracis population genetic database based upon whole-genome analysis to identify all single-nucleotide polymorphisms (SNPs) across a reference genome. Phylogenetic analysis has defined three major clades (A, B, and C), B and C being relatively rare compared to A. The A clade has numerous subclades, including a major polytomy named the trans-Eurasian (TEA) group. The TEA radiation is a dominant evolutionary feature of B. anthracis, with many contemporary populations having resulted from a large spatial dispersal of spores from a single source. Two autopsy specimens from the Sverdlovsk outbreak were deep sequenced to produce draft B. anthracis genomes. This allowed the phylogenetic placement of the Sverdlovsk strain into a clade with two Asian live vaccine strains, including the Russian Tsiankovskii strain. The genome was examined for evidence of drug resistance manipulation or other genetic engineering, but none was found. The Soviet Sverdlovsk strain genome is consistent with a wild-type strain from Russia that had no evidence of genetic manipulation during its industrial production. This work provides insights into the world's largest biological weapons program and provides an extensive B. anthracis phylogenetic reference. IMPORTANCE: The 1979 Russian anthrax outbreak resulted from an industrial accident at the Soviet anthrax spore production facility in the city of Sverdlovsk. Deep genomic sequencing of two autopsy specimens generated a draft genome and phylogenetic placement of the Soviet Sverdlovsk anthrax strain. While it is known that Soviet scientists had genetically manipulated Bacillus anthracis with the potential to evade vaccine prophylaxis and antibiotic therapeutics, there was no genomic evidence of this from the Sverdlovsk production strain genome. The whole-genome SNP genotype of the Sverdlovsk strain was used to precisely identify it and its close relatives in the context of an extensive global B. anthracis strain collection. This genomic identity can now be used for forensic tracking of this weapons material on a global scale and for future anthrax investigations. |

Obon-Santacana M , Lujan-Barroso L , Freisling H , Cadeau C , Fagherazzi G , Boutron-Ruault MC , Kaaks R , Fortner RT , Boeing H , Ramon Quiros J , Molina-Montes E , Chamosa S , Castano JM , Ardanaz E , Khaw KT , Wareham N , Key T , Trichopoulou A , Lagiou P , Naska A , Palli D , Grioni S , Tumino R , Vineis P , De Magistris MS , Bueno-de-Mesquita HB , Peeters PH , Wennberg M , Bergdahl IA , Vesper H , Riboli E , Duell EJ . Eur J Nutr 2016 56 (3) 1157-1168 PURPOSE: Acrylamide was classified as 'probably carcinogenic' to humans in 1994 by the International Agency for Research on Cancer. In 2002, public health concern increased when acrylamide was identified in starchy, plant-based foods, processed at high temperatures. The purpose of this study was to identify which food groups and lifestyle variables were determinants of hemoglobin adduct concentrations of acrylamide (HbAA) and glycidamide (HbGA) in 801 non-smoking postmenopausal women from eight countries in the European Prospective Investigation into Cancer and Nutrition (EPIC) cohort. METHODS: Biomarkers of internal exposure were measured in red blood cells (collected at baseline) by high-performance liquid chromatography/tandem mass spectrometry (HPLC/MS/MS) . In this cross-sectional analysis, four dependent variables were evaluated: HbAA, HbGA, sum of total adducts (HbAA + HbGA), and their ratio (HbGA/HbAA). Simple and multiple regression analyses were used to identify determinants of the four outcome variables. All dependent variables (except HbGA/HbAA) and all independent variables were log-transformed (log2) to improve normality. Median (25th-75th percentile) HbAA and HbGA adduct levels were 41.3 (32.8-53.1) pmol/g Hb and 34.2 (25.4-46.9) pmol/g Hb, respectively. RESULTS: The main food group determinants of HbAA, HbGA, and HbAA + HbGA were biscuits, crackers, and dry cakes. Alcohol intake and body mass index were identified as the principal determinants of HbGA/HbAA. The total percent variation in HbAA, HbGA, HbAA + HbGA, and HbGA/HbAA explained in this study was 30, 26, 29, and 13 %, respectively. CONCLUSIONS: Dietary and lifestyle factors explain a moderate proportion of acrylamide adduct variation in non-smoking postmenopausal women from the EPIC cohort. |
The Caribbean response to chikungunya
Olowokure B , Francis L , Polson-Edwards K , Nasci R , Quenel P , Aldighieri S , Rousset D , Gutierrez C , Ramon-Pardo P , Santos TD , Hospedales CJ . Lancet Infect Dis 2014 14 (11) 1039-40 As of Oct 6, 2014, the Caribbean Public Health Agency (CARPHA) has reported 7981 confirmed cases of chikungunya since December, 2013, when the first cases were reported from the French Caribbean island of Saint Martin.1 These are the first occurrences of autochthonously transmitted chikungunya to be identified in the region. As with several other viruses that have spread as a result of human behaviour and globalisation, local spread was probably originated in a traveller returning from an affected area overseas. | In an editorial, The Lancet commented that “The region [Caribbean] currently lacks adequate surveillance and virological testing infrastructure, which could hinder efforts to contain the virus.”2 The Caribbean has a long history of well established regional networks and has successfully eliminated viruses causing polio and measles, with extensive ongoing epidemiological and laboratory surveillance to maintain these achievements.3, 4, 5 Additionally, the countries of the Caribbean, CARPHA, Pan American Health Organization/WHO (PAHO/WHO), US Centers for Disease Control and Prevention (CDC), Institut Pasteur in French Guiana, and others have initiated preparedness and response efforts in relation to the International Health Regulations 2005 (IHR 2005).6 |
Disparities in current cigarette smoking prevalence by type of disability, 2009-2011
Courtney-Long E , Stevens A , Caraballo R , Ramon I , Armour BS . Public Health Rep 2014 129 (3) 252-260 OBJECTIVES: Smoking, the leading cause of disease and death in the United States, has been linked to a number of health conditions including cancer and cardiovascular disease. While people with a disability have been shown to be more likely to report smoking, little is known about the prevalence of smoking by type of disability, particularly for adults younger than 50 years of age. METHODS: We used data from the 2009-2011 National Health Interview Survey to estimate the prevalence of smoking by type of disability and to examine the association of functional disability type and smoking among adults aged 18-49 years. RESULTS: Adults with a disability were more likely than adults without a disability to be current smokers (38.8% vs. 20.7%, p<0.001). Among adults with disabilities, the prevalence of smoking ranged from 32.4% (self-care difficulty) to 43.8% (cognitive limitation). When controlling for sociodemographic characteristics, having a disability was associated with statistically significantly higher odds of current smoking (adjusted odds ratio = 1.57, 95% confidence interval 1.40, 1.77). CONCLUSIONS: The prevalence of current smoking for adults was higher for every functional disability type than for adults without a disability. By understanding the association between smoking and disability type among adults younger than 50 years of age, resources for cessation services can be better targeted during the ages when increased time for health improvement can occur. |
