Mortality and demographic recovery in early post-black death epidemics: Role of recent emigrants in medieval Dijon
2020
International audience; Objective and methodsWe analyze the influence of population movement on susceptibility to death and resilience during two epidemics occurring in Dijon soon after the Black Death. Using a specific program designed to propose links between entries in annual tax registers, we define tentative heads of household, the elapsed time since their first registration and their ties with other persons within the city.ResultsDuring the 1400 epidemic heads of household who were registered for 1–3 years die in large numbers, whereas during years without epidemics, their death rate is lower than that of heads of household who were registered longer. Recent registration is an epidemi…

In order to minimize risks of pathogen transmission with the development of ecotourism in Gabon, a seasonal inventory has been performed in five contrasted biotopes in Ivindo (INP) and Moukalaba-Doudou (MDNP) National Parks. A total of 10,033 hematophagous flies were captured. The Glossinidae, with six different species identified, was the most abundant group and constitutes about 60% of the captured flies compared to the Stomoxys (6 species also identified) and Tabanidae with 28% and 12%, respectively. The Glossinidae showed a higher rate of capture in primary forest and in research camps. In INP, the Stomoxys showed a higher rate of capture in secondary forest and at village borders, wher…
A divergent Anaplasma phagocytophilum variant in an Ixodes tick from a migratory bird; Mediterranean basin
2020
Anaplasma phagocytophilum (AP) has vast geographical and host ranges and causes disease in humans and domesticated animals. We investigated the role of northward migratory birds in the dispersal of tick-borne AP in the African-Western Palearctic. Ticks were collected from northward migratory birds trapped during spring migration of 2010 at two localities in the central Mediterranean Sea. AP DNA was detected by PCR (gltA and 16S rRNA) and variant determination was performed using ankA sequences. In total, 358 ticks were collected. One of 19 ticks determined as Ixodes was confirmed positive for AP DNA. The tick was collected from a woodchat shrike (Lanius senator senator) trapped in Greece, a…

Nanodaļiņu nogādāšana uz audzēju šūnām mezenhimālo cilmes šūnu un MDA-MB-231 šūnu 3D kopkultūras modelī
2016
Nanodaļiņas tiek uzskatītas par potenciālām transporta molekulām, kuras varētu nogādāt pretvēža zāles tieši uz audzēju šūnām. Bakalaura darba mērķis bija analizēt vai notiek nanodaļiņu pārnese uz audzēja šūnām mezinhimālo cilmes šūnu un MDA-MB-231 šūnu 3D kopkultūru modelī. Abas šūnu kultūras tika kultivēts S10 barotnē. Šūnu kultūru diferenciēšanai tika izvēlēts CD90 marķieris. MCŠ tika iezīmētas ar QD655 un pēc 6h inkubācijas tika veikta plūsmas citometrijas analīze. 3D kopkultūras modelis tika izveidots izmantojot PolyHEMA pārklājumu. QD pārnese uz vēža šūnām tika analizēta ar plūsmas citometriju pēc 48h kultivēšanas 3D kopkultūras modelī. 97% MCŠ 2D kultūrā pēc 6h inkubācijas uzņem QD655…
Epidemiology and surveillance of human (neuro)cysticercosis in Europe: is enhanced surveillance required?
2020
To report on relevant national surveillance systems of (N)CC and taeniasis (the infection with the adult tapeworm) in the European Union/European Economic Area and to assess the magnitude of (N)CC occurrence by retrieving information on cases for the period 2000-2016.(N)CC cases were retrieved via national reporting systems, a systematic literature search, contact with clinicians and a search for relevant 'International Statistical Classification of Diseases and Related Health Problems' (ICD)-based data.Mandatory notification systems for (N)CC were found in Hungary, Iceland and Poland. Ten cases were reported in Poland and none in Hungary and Iceland. Through the systematic literature revie…
Who should get COVID-19 vaccine first? A survey to evaluate hospital workers’ opinion
2021
Prospective planning of COVID-19 vaccines allocation will be essential to maximize public health and societal benefits while preserving equity. Decisions about how to allocate limited supplies of vaccines need to be clear about the criteria used in setting priorities, with a specific commitment to transparency and communication. The aim of our study was to think through these competing demands, focusing on the opinion of healthcare workers (HCWs). The primary endpoint of the study was to assess the opinion of all the HCWs in a University based Italian Hospital about the fairest priority order to COVID 19 vaccines and to understand on which criteria the prioritization preferences of HCWs are…
Abstract B041: A novel nanoparticular formulated tetravalent RNA cancer vaccine for treatment of patients with malignant melanoma
2016
Abstract Immunotherapeutic approaches have evolved as promising and valid alternatives to available conventional cancer treatments. Amongst others, vaccination with tumor antigen-encoding RNAs by local administration is currently successfully employed in various clinical trials. To allow for a more efficient targeting of antigen-presenting cells (APCs) we have developed a novel RNA immunotherapeutic for systemic application based on a fixed set of four liposome complexed RNA drug products (RNA(LIP)) each encoding one shared melanoma-associated antigen. Similar to other liposomal drugs, the four injectable RNA(LIP) products constituting the investigational medicinal product will be prepared …
Dracunculiasis: water-borne anthroponosis vs. food-borne zoonosis.
2019
Abstract Dracunculiasis is the first parasitic disease set for eradication. However, recent events related to the Dracunculus medinensis epidemiology in certain African countries are apparently posing new challenges to its eradication. Two novel facts have emerged: the existence of animal reservoirs (mainly dogs but also cats and baboons), and possibly a new food-borne route of transmission by the ingestion of paratenic (frogs) or transport (fish) hosts. Therefore, instead of being exclusively a water-borne anthroponosis, dracunculiasis would also be a food-borne zoonosis. The existence of a large number of infected dogs, mainly in Chad, and the low number of infected humans, have given ris…
Scientometrics analysis of research activity and collaboration patterns in Chagas cardiomyopathy.
2018
Background Chagas cardiomyopathy is a serious and common complication of Chagas disease. Methods Through bibliometric and Social Network Analysis, we examined patterns of research on Chagas cardiomyopathy, identifying the main countries, authors, research clusters, and topics addressed; and measuring the contribution of different countries. Results We found 1932 documents on Chagas cardiomyopathy in the MEDLINE database. The most common document type was ‘journal article’, accounting for 79.6% of the total (n = 1538), followed by ‘review’ (n = 217, 11.2%). The number of published records increased from 156 in 1980–1984 to 311 in 2010–2014. Only 2.5% were clinical trials. Brazil and the USA …
