AIMTo apply the Frontal Assessment Battery to cirrhotic patients with or without overt hepatic encephalopathy (OHE) and controls. METHODSThe frontal assessment battery (FAB) was applied to 87 patients with liver cirrhosis (16 with and 71 without OHE) and 40 control subjects without cirrhosis treated at the alcohol and liver outpatient clinics and the gastroenterology ward of the Cassiano Antônio de Moraes University Hospital (Hospital Universitário Cassiano Antônio de Moraes - HUCAM), Espírito Santo, Brazil. RESULTSThe average FAB score was lower for the cirrhotic than for the non-cirrhotic patients (10.6 ± 3.67 vs 12.25 ± 2.72, P = 0.015). The FAB score was lower for the cirrhotic patients with OHE than for the patients without OHE (8.25 ± 4.55 vs 11.14 ± 3.25, P = 0.027). The total FAB score was lower for the cirrhotic patients without OHE than for the non-cirrhotic patients, although this difference was not significant (11.14 ± 3.25 vs 12.25 ± 2.72, P = 0.067). Nevertheless, the difference in the scores on the subtest that assessed the ability to inhibit a response previously conditioned to a stimulus was significant (1.72 ± 0.93 vs 2.2 ± 0.85, P = 0.011). CONCLUSIONThe present study indicates that the FAB is a promising tool for outpatient minimal HE screening and the assessment of HE severity.

Dual Scheimpflug imaging as a screening method for occludable angles-a comparison with gonioscopy

International Journal of Ophthalmology(English edition) 2019年第2期12卷 241-245页

AIM: To evaluate dual Scheimpflug analyzer(Galilei) as a screening method for the diagnostic of gonioscopically narrow anterior chamber angles(ACA). METHODS: In 40 eyes of 40 patients with different ACA range, the ACA, anterior chamber volume(ACV) and anterior chamber depth(ACD) were analyzed using the dual Scheimpflug analyzer(Galilei G6 system). Correspondence between these parameters and Shaffer's classification based on gonioscopy were studied. Receiving operator characteristic(ROC) curves and partition analysis were used to determine the efficacy of the Galilei system in screening for narrow angles. Agreement(Kappa statistics), sensitivity, and specificity for each eye, according to Galilei measures, were also assessed. RESULTS: Shaffer's grade(from 0 to 4) were significantly associated with each of the measurements(Pder the ROC curve was largest(0.90) when ACD was used as the reference, and partition analysis demonstrated that those eyes were most adequately partitioned with an ACD of 2.86 mm with 100% sensitivity and 80% specificity. CONCLUSION: The Galilei is a secure, repeatable and noncontact screening method for narrow angles. However it does not provide sufficient information about the ACA anatomy to be considered a substitute for gonioscopy.

Probabilistic Approach in the Investigation of the Dynamics of a Duffing Oscillator

引用

Applied Mathematics 2015年第8期6卷 1282-1293页

作者： Jessé Rebello de souza Junior Claudio gomes Fernandes Naval Engineering department University of S&atilde o Paulo S&atilde o Paulo Brazil

We develop in this text a probabilistic approach to deterministic nonlinear systems. By studying the spectral properties of the Frobenius-Perron operator of a Duffing oscillator, relevant dynamic properties of the system are identified. Using the characteristics of the Dirac operator, the evolution of the probability density function is obtained for the Duffing oscillator, allowing important aspects of this system to be investigated analytically. A comparison with numerical simulation is carried out in order to validate the results obtained by the analytical approach as well as to verify the nonsymmetric features of the oscillator response.
