Outbreaks of Non-tuberculous Mycobacterium Infection in the United States

To date, 114 known outbreaks of human infection by non-tuberculous mycobacteria (NTM) have been associated with medical / other invasive procedures.  37 of these (32%) have reported from the United States.  The following chronology is abstracted from the Gideon e-book series. [1]   Primary references are available from the author.  1987     17 cases of Mycobacterium chelonae otitis media in Louisiana caused by contaminated water used by an ENT practice  1988    8 cases of Mycobacterium chelonae infection associated with a contaminated jet injector used in a Podiatry office.  1989 – 1990   16 cases of  Mycobacterium fortuitum respiratory tract colonization in Washington, D.C. among patients on an alcoholism rehabilitation ward  1991 *     6 cases of Mycobacterium fortuitum infection in Washington, related to contaminated electromyography needles  1995 – 1996    87 cases (in 16 states) of Mycobacterium abscessus soft tissue infection associated with use of a contaminated adrenal cortex extract  1998     6 cases of Mycobacterium mucogenicum  bacteremia among bone marrow transplant and oncology patients in Minnesota, related to use of  contaminated water in a hematology-oncology unit.  1999     10 cases of Mycobacterium abscessus arthritis  in Texas associated with  contaminated benzalkonium chloride used ...

Conclusion: The use of a microtunnel MEA enables the monitoring of the long-term development of human neuronal networks of cell populations that are relatively natural given their lack of astrocyte feeders. Significance: We report a more accurate method for culturing cortical neurons differentiated from hiPSCs, validating their use in elucidating cortical development and pathogenic mechanisms in humans.

(Aldert) PiersmaAbstractIn vivo, neural crest (NC) cells contribute critically to heart formation. The embryonic stem cells in the cardiac Embryonic Stem cell Test (ESTc) differentiate into a heterogeneous cell population including non-cardiomyocyte cells. The use of molecular biomarkers from different mechanistic pathways can refine quantitative embryotoxicity assessment. Gene expression levels representing different signalling pathways that could relate to beating cardiomyocyte for...

AbstractLow birth weight is associated with perinatal and long-term morbidity and mortality, and may be a result of abnormal placental development and function. In studies of singletons, associations have been reported between features of placental morphology and birth weight. Evaluating similar associations within twin pairs offers a unique opportunity to control for key confounders shared within a twin pair, including gestational age, parental characteristics, and intrauterine environment. Data from 3 studies in the United States that were completed from 2012 to 2013, 2006 to 2008, and 1959 to 1966 were used in our analy...

AbstractSelection due to survival or attrition might bias estimates of racial disparities in health, but few studies quantify the likely magnitude of such bias. In a large national cohort with moderate loss to follow-up, we contrasted racial differences in 2 stroke risk factors, incident hypertension and incident left ventricular hypertrophy, estimated by complete-case analyses, inverse probability of attrition weighting, and the survivor average causal effect. We used data on 12,497 black and 17,660 white participants enrolled in the United States (2003 –2007) and collected incident risk factor data approximately 10...

CONCLUSIONS: Human B1 cells are the key blood group A-specific B cells that have a moderate correlation with anti-A antibody titer and therefore constitute a potential therapeutic target for successful ABO-incompatible transplantation. PMID: 31432639 [PubMed - in process]
