New blood test for human TB may also identify people at most risk

(National Institute for Health Research) A new study conducted by researchers in Leicester and Nottingham has shown the potential for a new blood test to not only diagnose human tuberculosis (TB) but also identify those at most risk of developing the disease, according to findings published in medical journal Clinical Infectious Diseases.

LutzUrine cell-free DNA (cfDNA) is a valuable noninvasive biomarker for detecting cancer mutation, diagnosing infectious disease (eg, tuberculosis), monitoring organ transplantation, and prenatal screening. Conventional silica DNA extraction does not efficiently capture urine cfDNA, which is dilute (ng/mL) and highly fragmented (30 to 100 nt). The clinical sensitivity of urine cfDNA detection increases with decreasing target length, motivating us...

We describe a pediatric intensive care unit nurse with latent TB infection who developed hemoptysis and a lung infiltrate concerning for active TB. Her evaluation and contact investigation were facilitated by our institution's command center. Although TB was ultimately ruled out, this case tested our team-based care in response to a suspected high-consequence pathogen.

The objective of this study was to determine the prevalence of malaria/TB coinfection among bacteriologically confirmed adult TB patients at a national TB treatment centre in Uganda. Using a cross-sectional study design we enrolled 363 bacteriologically confirmed adult TB patients, and data on demographics and medical history was collected. Blood samples were tested for malaria blood smear, rapid malaria diagnostic test (RDT), complete blood count, haematological film analysis, HIV serology, and CD4+ and CD8+ cell counts. Malaria was defined as either a positive blood smear or RDT. The study participants were mostly male (...

Introduction: Despite the known association between the use of biologic medications and reactivation of latent tuberculosis infection (LTBI) the rate of LTBI among indigent Hispanic psoriatic patients living in the U.S. has not been studied. Little is known about the overall impact LTBI may pose on their treatment of psoriasis and/or psoriatic arthritis.

Human immunodeficiency virus (HIV), tuberculosis (TB) and malaria are commonly encountered when working in tropical countries and may have an impact upon anaesthesia, either as a direct result of the condition or due to interaction with the ...

Kannan, K.S. SubramanianAbstractFacile synthesis of Mg(OH)2 nanomaterials using seaweed Turbinaria ornata is reported herein. X-ray powder diffraction (XRD) analysis infer that crystal structures of Mg(OH)2 nanomaterials exhibit hexagonal brucite structure with thickness and lateral dimension around 7.75 nm and 16.29 nm (measured with Scherrer equation) respectively. FE-SEM images reveal that the flakes like structure were well ...

Abstract The causative agents of zoonotic bovine tuberculosis (bTB), Mycobacterium bovis and M. caprae, are members of the M. tuberculosis complex (MTC). Wildlife such as red deer infected with bTB are often without pathological findings, thus meat thereof may be classified as safe for human consumption. The culturing of MTC is time consuming and inappropriate to be applied with fresh meat and food. Therefore, a rapid method "PMA qPCR" to differentiate living and dead cells of MTC was developed in this study. By treating with 50 μM PMA™ dye, dead M. bovis BCG (≤104 cells/ml meat suspensio...
