Item Open Access Chagas disease: "the new HIV/AIDS of the Americas".(PLoS Negl Trop Dis, 2012) Hotez, Peter J; Dumonteil, Eric; Woc-Colburn, Laila; Serpa, Jose A; Bezek, Sarah; Edwards, Morven S; Hallmark, Camden J; Musselwhite, Laura W; Flink, Benjamin J; Bottazzi, Maria ElenaItem Open Access Geographic analysis of latent tuberculosis screening: A health system approach.(PloS one, 2020-01) Bonnewell, John P; Farrow, Laura; Dicks, Kristen V; Cox, Gary M; Stout, Jason EBackground
Novel approaches are required to better focus latent tuberculosis infection (LTBI) efforts in low-prevalence regions. Geographic information systems, used within large health systems, may provide one such approach.Methods
A retrospective, cross-sectional design was used to integrate US Census and Duke Health System data between January 1, 2010 and October 31, 2017 and examine the relationships between LTBI screening and population tuberculosis risk (assessed using the surrogate measure of proportion of persons born in tuberculosis-endemic regions) by census tract.Results
The median proportion of Duke patients screened per census tract was 0.01 (range 0-0.1, interquartile range 0.01-0.03). The proportion of Duke patients screened within a census tract significantly but weakly correlated with the population risk. Furthermore, patients residing in census tracts with higher population tuberculosis risk were more likely to be screened with TST than with an IGRA (p<0.001).Conclusion
The weak correlation between patient proportion screened for LTBI and our surrogate marker of population tuberculosis risk suggests that LTBI screening efforts should be better targeted. This type of geography-based analysis may serve as an easily obtainable benchmark for LTBI screening in health systems with low tuberculosis prevalence.Item Open Access Global guideline for the diagnosis and management of the endemic mycoses: an initiative of the European Confederation of Medical Mycology in cooperation with the International Society for Human and Animal Mycology.(The Lancet. Infectious diseases, 2021-12) Thompson, George R; Le, Thuy; Chindamporn, Ariya; Kauffman, Carol A; Alastruey-Izquierdo, Ana; Ampel, Neil M; Andes, David R; Armstrong-James, Darius; Ayanlowo, Olusola; Baddley, John W; Barker, Bridget M; Lopes Bezerra, Leila; Buitrago, Maria J; Chamani-Tabriz, Leili; Chan, Jasper FW; Chayakulkeeree, Methee; Cornely, Oliver A; Cunwei, Cao; Gangneux, Jean-Pierre; Govender, Nelesh P; Hagen, Ferry; Hedayati, Mohammad T; Hohl, Tobias M; Jouvion, Grégory; Kenyon, Chris; Kibbler, Christopher C; Klimko, Nikolai; Kong, David CM; Krause, Robert; Lee Lee, Low; Meintjes, Graeme; Miceli, Marisa H; Rath, Peter-Michael; Spec, Andrej; Queiroz-Telles, Flavio; Variava, Ebrahim; Verweij, Paul E; Schwartz, Ilan S; Pasqualotto, Alessandro CThe global burden of the endemic mycoses (blastomycosis, coccidioidomycosis, emergomycosis, histoplasmosis, paracoccidioidomycosis, sporotrichosis, and talaromycosis) continues to rise yearly and these infectious diseases remain a leading cause of patient morbidity and mortality worldwide. Management of the associated pathogens requires a thorough understanding of the epidemiology, risk factors, diagnostic methods and performance characteristics in different patient populations, and treatment options unique to each infection. Guidance on the management of these infections has the potential to improve prognosis. The recommendations outlined in this Review are part of the "One World, One Guideline" initiative of the European Confederation of Medical Mycology. Experts from 23 countries contributed to the development of these guidelines. The aim of this Review is to provide an up-to-date consensus and practical guidance in clinical decision making, by engaging physicians and scientists involved in various aspects of clinical management.Item Open Access Leptospirosis among hospitalized febrile patients in northern Tanzania.(Am J Trop Med Hyg, 2011-08) Biggs, Holly M; Bui, Duy M; Galloway, Renee L; Stoddard, Robyn A; Shadomy, Sean V; Morrissey, Anne B; Bartlett, John A; Onyango, Jecinta J; Maro, Venance P; Kinabo, Grace D; Saganda, Wilbrod; Crump, John AWe enrolled consecutive febrile admissions to two hospitals in Moshi, Tanzania. Confirmed leptospirosis was defined as a ≥ 4-fold increase in microscopic agglutination test (MAT) titer; probable leptospirosis as reciprocal MAT titer ≥ 800; and exposure to pathogenic leptospires as titer ≥ 100. Among 870 patients enrolled in the study, 453 (52.1%) had paired sera available, and 40 (8.8%) of these met the definition for confirmed leptospirosis. Of 832 patients with ≥ 1 serum sample available, 30 (3.6%) had probable leptospirosis and an additional 277 (33.3%) had evidence of exposure to pathogenic leptospires. Among those with leptospirosis the most common clinical diagnoses were malaria in 31 (44.3%) and pneumonia in 18 (25.7%). Leptospirosis was associated with living in a rural area (odds ratio [OR] 3.4, P < 0.001). Among those with confirmed leptospirosis, the predominant reactive serogroups were Mini and Australis. Leptospirosis is a major yet underdiagnosed cause of febrile illness in northern Tanzania, where it appears to be endemic.Item Open Access Zoonotic causes of febrile illness in malaria endemic countries: a systematic review.(The Lancet. Infectious diseases, 2020-02) Halliday, Jo EB; Carugati, Manuela; Snavely, Michael E; Allan, Kathryn J; Beamesderfer, Julia; Ladbury, Georgia AF; Hoyle, Deborah V; Holland, Paul; Crump, John A; Cleaveland, Sarah; Rubach, Matthew PFever is one of the most common reasons for seeking health care globally and most human pathogens are zoonotic. We conducted a systematic review to describe the occurrence and distribution of zoonotic causes of human febrile illness reported in malaria endemic countries. We included data from 53 (48·2%) of 110 malaria endemic countries and 244 articles that described diagnosis of 30 zoonoses in febrile people. The majority (17) of zoonoses were bacterial, with nine viruses, three protozoa, and one helminth also identified. Leptospira species and non-typhoidal salmonella serovars were the most frequently reported pathogens. Despite evidence of profound data gaps, this Review reveals widespread distribution of multiple zoonoses that cause febrile illness. Greater understanding of the epidemiology of zoonoses in different settings is needed to improve awareness about these pathogens and the management of febrile illness.
