BACKGROUND The aim of this multicentric prospective study in India was to assess the performance of the QuantiFERON TB-Gold in tube (QFT-GIT), Tuberculin Skin Test (TST) and microbiological results as additional tools for diagnosing active tuberculosis (TB) and latent infection (LTBI) according to Human Immunodeficiency Virus (HIV) status. METHODS Individuals with and without active TB and HI...
We introduce the concept of a quantum background and a functor QFT. In the case that the QFT moduli space is smooth formal, we construct a flat quantum superconnection on a bundle over QFT which defines algebraic structures relevant to correlation functions in quantum field theory. We go further and identify chain level generalizations of correlation functions which should be present in all qua...

QuantiFERON® TB Gold In-Tube (referred to hereafter as QFT-3G), an improved version of the QuantiFERON® TB-2G (QFT-2G), was approved in April 2009 as a diagnostic kit for extracorporeal tuberculosis (TB) infection. QFT-3G was available for purchase in July 2009. Subsequent problems with blood collection tubes led to the withdrawal of QFT-3G sales; however, it was re-released in January 2010 and...
BACKGROUND There is limited data on the effect of HIV status and CD4 counts on performance of Interferon-g Release assays (IGRAs) for diagnosis of latent tuberculosis infection (LTBI). METHODS A cross sectional study was conducted to assess the prevalence of and risk factors for a positive diagnostic test for LTBI, using tuberculin skin test (TST) and IGRAs among HIV-discordant couples in Zam...
Health care workers (HCW's) are always at an increased risk of contracting tuberculosis (TB) infection. In Saudi Arabia, Interferon Gamma Release Assay (IGRA) has not been evaluated as a screening tool for latent TB infection (LTBI) among HCW's considering their high demographic diversity. During February 2012 to January 2015 a cross sectional study has been conducted in a tertiary care center ...
We show that there are significant conceptual differences between QM and QFT which make it difficult to view QFT as just a relativistic extension of the principles of QM. The root of this is a fundamental distiction
The quantum string emission by Black Holes is computed in the framework of the “string analogue model” (or thermodynamical approach), which is well suited to combine QFT and string theory in curved backgrounds (particulary here, as black holes and strings posses intrinsic thermal features and temperatures). The QFT-Hawking temperature TH is upper bounded by the string temperature TS in the blac...
OBJECTIVES To address whether the effect of BCG vaccination against tuberculosis (TB) infection lasts to adulthood. METHODS A cross-sectional study on the prevalence of latent TB infection (LTBI) among HIV-negative men, using QuantiFERON-TB Gold In-tube (QFT-IT), was conducted at a prison in northern Taiwan with >3000 inmates. A QFT-IT ≥0.35 IU/ml was defined as LTBI. A QFT-IT ≥0.7 IU/ml was ...
