Background of Study: The reliability of microscopic techniques has become questionable in most endemic regions in Africa leading to its decreased utilization and increased utilization of RDT kits and other laboratory-based methods. Objective: To evaluate the performance of Rapid Diagnostic Test (RDT) kits and nest Polymerase Chain Reaction (nPCR) methods in detecting malaria infections among pregnant women visiting private hospitals in Onitsha district area of Anambra State, South-Eastern Nigeria. Methods: A total of 100 blood samples of pregnant women submitted to medical laboratory units of private maternal hospitals for malaria diagnosis in Onitsha district area were randomly selected for this study. Diagnosis was through microscopy, RDT kit (SD Bioline Pf-only test) and nPCR. Results: Pregnant cohorts had 95, 90 and 12 positive samples confirmed through microscopy RDT and nPCR respectively. RDT had a sensitivity and specificity of 89.47% and 0% while nPCR recorded sensitivity and specificity of 12.63% and 100% respectively. RDT and nPCR have a positive predictive value (PPV) of 94.44% of 100% respectively. Conclusion: This study revealed that nPCR is more efficient and reliable when compared with RDT in the diagnosis of malaria infection, having recorded the highest value for positive predictive value (PPV) and specificity than the RDT among pregnant women.

Perimesencephalic subarachnoid hemorrhage (P-SAH) is a benign subset of subarachnoid hemorrhage. Only two cases of P-SAH during pregnancy have been reported in the literature. We describe a case of P-SAH detected at 29 weeks’ gestation, arose with severe bilateral frontal headache, neck rigidity, and vomiting. A diagnosis of P-SAH was confirmed on magnetic resonance angiography with no evidence of vascular malformation or bleeding sources and conservatively treated. Hemorrhage, vasospasm, and cerebellar edema observed on initial magnetic resonance angiography resolved after two months. The clinical course of P-SAH during pregnancy appears to be favorable. Our case shows for the first time in literature that magnetic resonance angiography is a valid diagnostic test for P-SAH during pregnancy that circumvents radiological risk associated with conventional imaging.

Stability of PD/PID Control for Robot Arm Tracking: Lyapunov Analysis and Input-output Interpretations

Stability of PD/PID Control for Robot Arm Tracking: Lyapunov...

＜正＞ In this paper, we investigate the stability feature of PD/PID control for the trajectory tracking of robot manipulators. Instead of studying the ordinary position and velocity errors, we focus on the generalized tracking errors associated with the error dynamics proposed by [14]. Using the Lyapunov approach, the stability conditions are obtained in terms of controller gains and the bounds of dynamic parameters and reference trajectory. We also show that the problem can be well interpreted from input-output property point of view. Using the input-output formulation, the PD/PID tracking can be expressed as a regulator problem for a nonlinear feedback system whose forward block is a finite gain map in L2e and feedback block is a nonlinear finite gain map in L∞e. The gain condition obtained therefore can be regarded as a nonlinear version of the small-gain theorem [5].

作者： Wang Dianhui Department of Computer Science and Computer Engineering, LaTrobe University,Melbourne , vic3086,Australia

＜正＞This paper aims at developing rule-based fault diagnosis （RBFD） systems using data mining techniques,where we address a problem of generating rules for faults with low probability of occurrence but considerable conceptual importance. Main technical contributions include a multilayer structure of rule generation and use,and a regularization model embedding some information on recognition rate,coverage rate and generalization capability for rule optimization. A case study is carried out by an engine diagnostics to illustrate effectiveness of our methodology.

两个比一个好：ISO 9001和SOX的共同点有助于加强内部控制

最近，出于管理需要和个人的好奇，我仔细研读了《萨班斯法案》（SOX）。我所从事的工作让我发现ISO 9001和SOX之间存在许多相似和不同之处，并列出了一个ISO 9001条款的清单，这些条款如果付诸实施能够直接对SOX的合规性起到支持作用。

Hepatitis C virus genotypes distribution and transmission risk factors in Luxembourg from 1991 to 2006

World Journal of Gastroenterology 2008年第8期14卷 1237-1243页

作者： Francois Roman Karin Hawotte Daniel Struck Anne-Marie Ternes Jean-Yves Servais vic Arendt Patrick Hoffman Robert Hemmer Thérèse Staub Carole Seguin-Devaux Jean-Claude Schmit Retrovirology Laboratory CRP-Santé 84 rue Val fleuri L-1526 Luxembourg Centre Hospitalier de Luxembourg 4 rue Barblé L-1210 Luxembourg Centre Pénitentiaire de Luxembourg UmKuelebierg L-5299 Schrassig Luxembourg Retrovirology Laboratory CRP-Santé 84 rue Val fleuri L-1526 Luxembourg Centre Hospitalier de Luxembourg 4 rue Barblé L-1210 Luxembourg

AIM： To analyze the Hepatitis C virus （HCV） genotype distribution and transmission risk factors in a population of unselected patients in Luxembourg.METHODS： Epidemiological information （gender, age and transmission risks） were collected from 802 patients newly diagnosed for hepatitis C and living in Luxembourg, among whom 228 patients referred from prison. Genotyping using 5＇noncoding （5＇NC） sequencing was performed. We compared categorical data using the Fisher＇s exact F-test and odds ratios （OR） were calculated for evaluating association of HCV genotype and risk factors.RESULTS： The sex ratio was predominantly male （2.2） and individuals aged less than 40 years represented 49.6% of the population. Genotype 1 was predominant （53.4%） followed by genotype 3 （33%）. Among risk factors, intravenous drug usage （IVDU） was the most frequently reported （71.4%） followed by medical-related transmission （17.6%） including haemophilia, transfusion recipients and other nosocomial reasons. Genotype 3 was significantly associated to IVDU （OR = 4.84, P 〈 0.0001） whereas genotype 1 was significantly associated with a medical procedure （OR = 2.42, P 〈 0.001）. The HCV genotype distribution from inmate patients differed significantly from the rest of the population （Chi-square test with four degrees of freedom, P 〈 0.0001） with a higher frequency of genotype 3 （46.5% vs 27.5%） and a lower frequency of genotype 1 and 4 （44.7% vs 56.8% and 5.3% vs 9.6%, respectively）. IVDU was nearly exclusively reported as a risk factor in prison.CONCLUSION： We report the first description of the HCV genotype distribution in Luxembourg. The repartition is similar to other European counties, with one of the highest European prevalence rates of genotype 3 （33%）. Since serology screening became available in 2992, IVDU remains the most common way of HCV transmission in Luxembourg.
