Question: Context: Associations between multidrug resistance and the Mycobacterium tuberculosis Beijing genotype have been described mainly in populations with poor tuberculosis (TB) control such as prisons and inner cities, and may reflect shared risk factors rather than a biological association.', 'To study the association between genotype and drug resistance among TB patients in a population with adequate TB control.', 'Three rural districts in Vietnam. The study was performed at the Pham Ngoc Thach Tuberculosis and Lung Disease Hospital, Ho Chi Minh City, and the Tien Giang Provincial Tuberculosis and Lung Disease Hospital, My Tho, Vietnam.', 'Pretreatment sputum specimens were collected for culture, drug susceptibility testing and spoligotyping of all sputum smear-positive pulmonary TB patients consecutively diagnosed over a 3-year period.', 'Beijing genotype infections were observed in 614 of 1744 (35%) patients. Beijing strains were more common among female (adjusted odds ratio [aOR] 1.4, P = 0.005), young (aOR 2.8, P < 0.001) and previously treated patients (aOR 2.4, P < 0.001). The Beijing genotype was associated with any resistance (aOR 3.7, P < 0.001) and multidrug resistance (aOR 6.8, P < 0.001) among new patients, and with any resistance (aOR 2.7, P = 0.005) but not with multidrug resistance (aOR 1.4, P = 0.545) among previously treated patients.
Answer: In Vietnam, Beijing genotype is associated with young age and in new patients with multidrug resistance despite adequate TB control, suggesting a biological association. This potentially undermines the effectiveness of TB control in countries where Beijing genotype infections are common.

Answer: Is the Beijing genotype associated with young age and multidrug-resistant tuberculosis in rural Vietnam?

Question: Context: Accumulating evidences indicated that lncRNAs play crucial regulatory roles in oncogenesis and progression of cancers. BRAF activated non-coding RNA (BANCR) has been identified to contribute to the progression of some human cancers. However, the relationship between BANCR and bladder cancer (BC) is largely unclear.', 'BANCR expression levels in BC, paired non-cancer tissues and BC cell lines were detected by real-time quantitative RT-PCR (qRT-PCR). The relationships between BANCR expression levels and the clinical characteristics were evaluated. BANCR expression was enhanced by transfecting a pcDNA-BANCR vector. We used both CCK-8 assay and Edu assay to detect cell proliferation. We also detect cell apoptosis and migration by using ELISA assay, Flow cytometry and transwell assay, respectively. All statistical analyses were executed by using the SPSS 20.0 software.', 'BANCR expression levels were remarkably decreased in BC tissues compared with adjacent noncancerous tissues. BANCR expression levels in two BC cell lines were also significantly down-regulated. Clinicopathologic analysis revealed that low BANCR expression was positively correlated with TNM stage, but not associated with other clinicopathological characteristics. BANCR has been successfully overexpressed in BC cell lines (T24 and SW780) by transfecting a pcDNA-BANCR vector. Cell proliferation inhibition, apoptosis induction and migration suppression were also observed in pCDNA-BANCR-transfected T24 and SW780 cells.
Answer: These data suggested that BANCR represents a tumor suppressor player in bladder cancer, contributes to tumor proliferation, apoptosis and migration, and may serve as a new candidate biomarker and a potential therapeutic target for patients with BC.

Answer: Does over-expression of long noncoding RNA BANCR inhibit malignant phenotypes of human bladder cancer?

Question: Context: Childhood uveitis is a vision-threatening inflammatory eye disease commonly attributed to juvenile idiopathic arthritis (JIA). The pathogenesis is poorly understood, which makes clinical management challenging. We analyzed soluble mediators in ocular fluid (aqueous humor [AqH]) and serum from children with JIA-associated uveitis and common childhood uveitis to identify potential biomarkers and investigate the ocular microenvironment of this sight-threatening eye disease.', 'AqH (n=73) and paired serum (n=66) samples were analyzed for 51 soluble mediators of inflammation by multiplex immunoassay. Twenty-one children with JIA-associated uveitis were compared to 15 children with chronic anterior uveitis without arthritis, 29 children with noninfectious idiopathic uveitis, and 8 children with noninflammatory conditions (controls). For visualization of the joint effect of multiple mediators, we used the radial coordinate visualization (Radviz) method. Optimal biomarker level cutoffs were also determined.', 'The levels of interleukin-29 (IL-29)/interferon-1 (IFN1) were decreased (P<0.001) and the levels of latency-associated peptide and osteoprotegerin were increased (P=0.002 and P=0.001, respectively) in samples of AqH, but not serum, from patients with JIA-associated uveitis. Multivariate analysis correcting for disease activity and treatment revealed that intraocular levels of IL-29/IFN1 were specifically decreased in patients with JIA-associated uveitis as compared to those with idiopathic uveitis. Indeed, JIA-associated uveitis patients and idiopathic uveitis patients showed distinct profiles of intraocular soluble mediators. IL-29/IFN1 showed a high area under the curve value (0.954), with 23.5 pg/ml as the optimal cutoff value.
Answer: We identified IL-29/IFN1 as an intraocular biomarker for JIA-associated uveitis, which suggests that aberrant IFN signaling might be important in JIA-associated uveitis and distinct from other forms of childhood uveitis.

Answer:
Does ocular Fluid Analysis in Children reveal Interleukin-29/Interferon-1 as a Biomarker for Juvenile Idiopathic Arthritis-Associated Uveitis?
