Hypersensitivity Pneumonitis Associated with Environmental Mycobacteria

A previously healthy man working as a machine operator in an automotive factory developed respiratory symptoms. Medical evaluation showed abnormal pulmonary function tests, a lung biopsy showed hypersensitivity pneumonitis, and his illness was traced to his work environment. His physician asked the employer to remove him from exposure to metalworking fluids. Symptoms reoccurred when he was later reexposed to metalworking fluids, and further permanent decrement in his lung function occurred. Investigation of his workplace showed that five of six large reservoirs of metalworking fluids (cutting oils) grew Mycobacterium chelonae (or Mycobacterium immunogenum), an organism previously associated with outbreaks of hypersensitivity pneumonitis in automaking factories. His lung function remained stable after complete removal from exposure. The employer, metalworking fluid supplier, union, and the National Institute for Occupational Safety and Health were notified of this sentinel health event. No further cases have been documented in this workplace

From easing lockdowns to scaling up community-based coronavirus disease 2019 screening, testing, and contact tracing in Africa-shared approaches, innovations, and challenges to minimize morbidity and mortality

CITATION: Nachega, J. B. et al. 2021. From easing lockdowns to scaling up community-based coronavirus disease 2019 screening, testing, and contact tracing in Africa-shared approaches, innovations, and challenges to minimize morbidity and mortality. Clinical infectious diseases, 72(2):327–331. doi:10.1093/cid/ciaa695The original publication is available at https://academic.oup.com/cid/The arrival of coronavirus disease 2019 (COVID-19) on the African continent resulted in a range of lockdown measures that curtailed the spread of the infection but caused economic hardship. African countries now face difficult choices regarding easing of lockdowns and sustaining effective public health control measures and surveillance. Pandemic control will require efficient community screening, testing, and contact tracing; behavioral change interventions; adequate resources; and well-supported, community-based teams of trained, protected personnel. We discuss COVID-19 control approaches in selected African countries and the need for shared, affordable, innovative methods to overcome challenges and minimize mortality. This crisis presents a unique opportunity to align COVID-19 services with those already in place for human immunodeficiency virus, tuberculosis, malaria, and non communicable diseases through mobilization of Africa's interprofessional healthcare workforce. By addressing the challenges, the detrimental effect of the COVID-19 pandemic on African citizens can be minimized.https://academic.oup.com/cid/article/72/2/327/5849218?login=truePublishers versio

The Microsoft Geospatial Library

In SQL Server 2008, Microsoft introduced support for geospatial data, with a rich set of spatial queries and constructions, in both Cartesian and geodetic coordinates. Most of this functionality is also available as an independent (free download) .NET library. This talk will focus on this library, touching on the differences in functionality between its TSQL and C# interfaces
