Abstract

Microscopic identification of active pulmonary tuberculosis (PTB) from direct smears of sputum (DS) is widely used for detection, but has limited sensitivity. Here, we assessed the yield of acid-fast bacilli (AFB) detection in processed sputum smears (PSS). Sputum samples were simultaneously analyzed by direct sputum smearing and after chemical treatment and spontaneous sedimentation. Of the 1,719 samples analyzed, 16.4% were positive for AFB in conventional DS and 21.4% in PSS, corresponding to a 30% increase in detection. Increased sensitivity from analyzing PSS and better safety protocols will contribute to improved detection and control of the disease.

Attention Score in Context

Attention Score in Context

This research output has an Altmetric Attention Score of 1. This is our high-level measure of the quality and quantity of online attention that it has received. This Attention Score, as well as the ranking and number of research outputs shown below, was calculated when the research output was last mentioned on 17 May 2018.
All research outputs
#20,663,600
of 25,382,440 outputs
Outputs from Revista da Sociedade Brasileira de Medicina Tropical
#740
of 1,193 outputs
Outputs of similar age
#268,557
of 343,807 outputs
Outputs of similar age from Revista da Sociedade Brasileira de Medicina Tropical
#7
of 12 outputs
Altmetric has tracked 25,382,440 research outputs across all sources so far. This one is in the 10th percentile – i.e., 10% of other outputs scored the same or lower than it.
So far Altmetric has tracked 1,193 research outputs from this source. They receive a mean Attention Score of 2.9. This one is in the 20th percentile – i.e., 20% of its peers scored the same or lower than it.
Older research outputs will score higher simply because they've had more time to accumulate mentions. To account for age we can compare this Altmetric Attention Score to the 343,807 tracked outputs that were published within six weeks on either side of this one in any source. This one is in the 11th percentile – i.e., 11% of its contemporaries scored the same or lower than it.
We're also able to compare this research output to 12 others from the same source and published within six weeks on either side of this one. This one is in the 25th percentile – i.e., 25% of its contemporaries scored the same or lower than it.
