Project description:We describe a dataset of account information and detailed transaction records for a digital complementary currency in Kenya. This "Sarafu system" initially encompassed several local, physical community currencies, which began transitioning to a feature-phone mobile interface in 2017. One unit of "Sarafu" is roughly equivalent in value to a Kenyan shilling. The published data includes anonymized account information for around 55,000 users and records of all Sarafu transactions conducted from January 25, 2020 to June 15, 2021. Transactions totaling around 300 million Sarafu capture various economic and financial activities such as purchases, transfers, and participation in savings and lending groups. So-called "chamas" are key to the operation of the Sarafu system and many such groups are labeled in the data. Describing this data contributes to research on the operation of community currencies, monetary systems, and economic networks in marginalized, food insecure areas. The observation period includes the first year of the COVID-19 pandemic and several documented pilot projects and interventions.
Project description:Yellow fever virus remains a major threat in low resource countries in South America and Africa despite the existence of an effective vaccine. In Senegal and particularly in the eastern part of the country, periodic sylvatic circulation has been demonstrated with varying degrees of impact on populations in perpetual renewal. We report an outbreak that occurred from October 2020 to February 2021 in eastern Senegal, notified and managed through the synergistic effort yellow fever national surveillance implemented by the Senegalese Ministry of Health in collaboration with the World Health Organization, the countrywide 4S network set up by the Ministry of Health, the Institut Pasteur de Dakar, and the surveillance of arboviruses and hemorrhagic fever viruses in human and vector populations implemented since mid 2020 in eastern Senegal. Virological analyses highlighted the implication of sylvatic mosquito species in virus transmission. Genomic analysis showed a close relationship between the circulating strain in eastern Senegal, 2020, and another one from the West African lineage previously detected and sequenced two years ago from an unvaccinated Dutch traveler who visited the Gambia and Senegal before developing signs after returning to Europe. Moreover, genome analysis identified a 6-nucleotide deletion in the variable domain of the 3'UTR with potential impact on the biology of the viral strain that merits further investigations. Integrated surveillance of yellow fever virus but also of other arboviruses of public health interest is crucial in an ecosystem such as eastern Senegal.
Project description:ObjectiveTo report summative data from the American College of Veterinary Emergency and Critical Care (ACVECC)-Veterinary Committee on Trauma (VetCOT) registry, with further individual evaluation of university and private practices and level I and II Veterinary Trauma Centers (VTCs).DesignMulti-institutional registry data report, January 1, 2020, to December 31, 2021.SettingVTCs identified and verified by ACVECC-VetCOT.AnimalsDogs and cats with evidence of trauma.InterventionsData were input to a web-based data capture system (REDCap) by data entry personnel trained in registry software use and operational definitions of data variables. Patient data on demographics, trauma type, preadmission care, trauma severity assessment at presentation (modified Glasgow Coma Score and Animal Trauma Triage score), key laboratory parameters, interventions, and outcome were collected. Summary descriptive data for each species are reported.Measurements and main resultsTwenty-two VTCs contributed data to the VetCOT registry during a 24-month period, culminating in a total of 9758 complete trauma case records for dogs and 11734 for cats. Head trauma in dogs and cats was seen at a higher percentage in both university-only VTCs (encompassing both level I and II) (20.1% and 24.1%, respectively) and level I-only VTCs (24.3% and 24.1%, respectively), in comparison to private-only VTCs (encompassing both level I and II) (13.5% and 16.2%, respectively) and individual level II VTCs (14.1% and 18.9%, respectively). Canine and feline surgical procedures were performed at a higher percentage at university VTCs (50% and 40.5%, respectively) compared to private VTCs (39.2% and 28.6%, respectively). Overall survival to discharge for dogs and cats remains high at 93.1% and 83.6%, respectively.ConclusionsThe VetCOT registry has continued to show powerful potential in collating a large, multifaceted, international dataset in trauma for both dogs and cats. As published in previous VetCOT registry reports, survival to discharge has remained static across both university and private practice veterinary hospitals; however, further breakdown has identified university and level I VTCs admitting and managing a higher number of head traumas, as well as university VTCs performing a higher proportion of surgical procedures. Data from this registry will continue to aid in the design of clinical trials, prospective observational studies, and translational research, which will improve the understanding and outcome of trauma patients.
Project description:This overview of severe acute respiratory syndrome coronavirus 2 circulation over 1.5 years in Guinea demonstrates that virus clades and variants of interest and concern were progressively introduced, mostly by travellers through Conakry, before spreading through the country. Sequencing is key to following virus evolution and establishing efficient control strategies.
