Discordance rates between preliminary and final radiology reports on cross-sectional imaging studies at a level 1 trauma center.

Rationale And Objectives: The goal was to determine discordance rates between preliminary radiology reports provided by on-call radiology house staff and final reports from attending radiologists on cross-sectional imaging studies requested by emergency department staff after hours.

Materials And Methods: A triplicate carbon copy reporting form was developed to provide permanent records of preliminary radiology reports and to facilitate communication of discrepant results to the emergency department. Data were collected over 21 weeks to determine the number of discordant readings.

Fission yeast dam1-A8 mutant is resistant to and rescued by an anti-microtubule agent.

The Dam1/DASH outer kinetochore complex is required for high-fidelity chromosome segregation in budding and fission yeast. Unlike budding yeast, the fission yeast complex is non-essential, however it promotes bipolar microtubule attachment in conjunction with microtubule-depolymerising kinesin-8 Klp5 and Klp6. Here, we screened for dam1 temperature sensitive mutants in a klp5 null background and identified dam1-A8 that contains two amino acid substitutions in the C-terminus (H126R and E149G).

Comparison of minimally invasive and conventional open posterolateral lumbar fusion using magnetic resonance imaging and retraction pressure studies.

Objective: To determine whether minimally invasive lumbar spinal fusion results in less paraspinal muscle damage than conventional open posterior fusion.

Methods: The maximum intramuscular pressure (IMP) generated by a minimally invasive and standard open retractor was compared in cadavers using an ultra-miniature pressure transducer. In a second clinical study, eight patients with either minimally invasive or open posterolateral lumbar spinal fusion underwent magnetic resonance imaging (MRI) scanning approximately 6 months post surgery.

Assessment of severe malnutrition among hospitalized children in rural Kenya: comparison of weight for height and mid upper arm circumference.

Context: Severe malnutrition has a high mortality rate among hospitalized children in sub-Saharan Africa. However, reports suggest that malnutrition is often poorly assessed. The World Health Organization recommends using weight for height, but this method is problematic and often not undertaken in practice.

Recombinant BCG exporting ESAT-6 confers enhanced protection against tuberculosis.

The live tuberculosis vaccines Mycobacterium bovis BCG (bacille Calmette-Guérin) and Mycobacterium microti both lack the potent, secreted T-cell antigens ESAT-6 (6-kDa early secretory antigenic target) and CFP-10 (10-kDa culture filtrate protein). This is a result of independent deletions in the region of deletion-1 (RD1) locus, which is intact in virulent members of the Mycobacterium tuberculosis complex. To increase their immunogenicity and protective capacity, we complemented both vaccines with different constructs containing the esxA and esxB genes, which encode ESAT-6 and CFP-10 respectively, as well as a variable number of flanking genes.
