What Causes Irritability?
Discussion Child abuse or non-accidental trauma is a clinical diagnosis. It is the constellation of history, physical examination, radiographic evaluation, laboratory testing and investigation that determines if child abuse has occurred. Irritability caused by fractures or other trauma can be a presenting symptom of abuse. Fractures can be a presentation but they are also common problems not associated with abuse. Femoral shaft fractures are estimated to account for only 1.6% of all fractures in children, therefore they are potentially more suspicious for child abuse. A review of femur fractures can be found here. A review...

Does high adherence to contact precautions lead to low in-hospital transmission of multi-drug-resistant micro-organisms in the endemic setting?
Conclusion: High adherence coupled with continuous monitoring of CPs correlated with a very low in-hospital transmission rate. These results indicate that CPs are highly effective if routine monitoring of adherence is implemented. (Source: Current Awareness Service for Health (CASH))

Shrinking to survive: Bacteria adapt to a lifestyle in flux
(Washington University in St. Louis) E. coli adapt to survive sudden starvation. Biologists from Washington University in St. Louis and Stanford showed that when E. coli cells lack nutrients, the cytoplasm becomes more dense as its volume decreases, probably because of water loss. At the same time, the periplasm increases in volume as the inner membrane pulls away from the outer membrane. (Source: EurekAlert! - Biology)

Type III secretion system effectors form robust and flexible intracellular virulence networks
Infections with many Gram-negative pathogens, including Escherichia coli, Salmonella, Shigella, and Yersinia, rely on type III secretion system (T3SS) effectors. We hypothesized that while hijacking processes within mammalian cells, the effectors operate as a robust network that can tolerate substantial contractions. This was tested in vivo using the mouse pathogen Citrobacter rodentium (encoding 31 effectors). Sequential gene deletions showed that effector essentiality for infection was context dependent and that the network could tolerate 60% contraction while maintaining pathogenicity. Despite inducing very different co...
