OBJECTIVE To investigate the prognostic factors of tuberculous meningitis (TBM) and develop strategies for the improvement of clinical efficacy. METHODS A total of 156 TBM patients were retrospectively reviewed. The demographic characteristics, underlying diseases, clinical features, laboratory findings, bacteriologic test, images, use of steroids, mannitol and anti-TB drugs, surgery or drain...
The aim of this study was to examine the performance of T-SPOT.TB on cerebrospinal fluid (CSF) and peripheral blood (PB) in diagnosis of tuberculous meningitis (TBM) in China. Of 100 patients with presumed TBM prospectively enrolled from Sep 2012 to Oct 2014, 53 were TBM (21 definite and 32 probable TBM cases) and 37 were non-TBM cases; the other 10 patients were excluded from analysis due to i...
Although tribimaximal mixing (TBM) and quark-lepton complementarity (QLC) are both compatible with experimental data within one standard deviation (1σ), the TBM and QLC assumptions are mutually exclusive by 56σ. [email protected] [email protected] Two popular assumptions in particle phenomenology model building are tribimaximal mixing (TBM) and quark-lepton complementarity(QLC). In t...
Testing TBM (Test Blanket Modules) is one of important engineering test objectives in ITER project. China is performing the TBM design and R&D based on Chinese development strategy of fusion DEMO. Helium-cooled test blanket module concept with ceramic breeder for testing on ITER will be one of the basic options in China. The current progress and status on design and R&D of CH HC-SB (Chinese Hel...
Tuberculous meningitis (TBM) and acute bacterial meningitis (ABM) cause substantial mortality and morbidity in both children and adults. Identification of poor prognostic factors at patient's admission could prepare physicians for more aggressive monitoring of patients with meningitis. The objective of this study was to determine the predictive value of neurological features to differentiate AB...
We present novel multivariate tensor-based morphometry (TBM) for characterizing white matter abnormalities. Traditionally TBM is used in quantifying tissue volume changes in a massive univariate fashion. At each voxel, the Jacobian determinant obtained from TBM is used as the response variable in a general linear model (GLM) and a test statistic is constructed. However, this obvious approach ca...
BACKGROUND Tuberculous meningitis (TBM) is a severe complication of tuberculosis predominantly affecting young children. Early treatment is vital to prevent morbidity and mortality, emphasizing the importance of early diagnosis. The lack of sensitive methods for early diagnosis is the most common cause of delay. Attempts have been made to develop simplified tests for tuberculosis, but their dia...
Tuberculous meningitis (TBM), the most devastating manifestation of tuberculosis, is often missed or overlooked because of nonspecific symptoms and difficulties in diagnosis. It continues to be an important cause of neurologic handicap in resource-poor countries. Owing to the suboptimal performance of diagnostic tests of TBM, diagnosis relies on thorough history, clinical examination, and relev...
BACKGROUND Tuberculous meningitis (TBM) is difficult to diagnose promptly. The utility of the Xpert MTB/RIF test for the diagnosis of TBM remains unclear, and the effect of host- and sample-related factors on test performance is unknown. This study sought to evaluate the sensitivity and specificity of Xpert MTB/RIF for the diagnosis of TBM. METHODS AND FINDINGS 235 South-African patients with...
حفاری مکانیزه تمام مقطع تونل‌ها توسط ماشین، دارای تاریخچه‌ای نزدیک به پنجاه سال می‌باشد. بررسی عملکرد، بخش مهمی از هر پروژه حفر تونل بوده و می‌تواند نقش اساسی در انتخاب روش و ماشین حفاری داشته باشد. در این مقاله پیش‌بینی سرعت نفوذ TBM برمبنای روش NTH در تونل قمرود مورد مطالعه قرار گرفته است. مهمترین مزیت این روش منظور کردن تأثیر شرایط زمین و خواص توده‌سنگ می‌باشد. محاسبات انجام گرفته سرعت نفوذ ...
