A case of vitamin B12 deficiency neurological syndrome in a young adult due to late-onset cobalamin C (CblC) deficiency: a diagnostic challenge

Vitamin B12 deficiency can present with neurologic and psychiatric symptoms without macrocytic anaemia. We describe a case of late-onset cobalamin C deficiency which typically presents with normal serum vitamin B12 concentrations, posing an additional diagnostic challenge. A 23-year-old woman with decreased muscle strength and hallucinations was diagnosed with ‘catatonic depression’ and admitted to a residential mental health facility. She was referred to our hospital for further investigation 3 months later. Heteroanamnesis revealed that the symptoms had been evolving progressively over several months. Magnetic resonance imaging (MRI) of the brain showed diffuse symmetrical white matter lesions in both hemispheres. Routine laboratory tests including vitamin B12 and folic acid were normal except for a slight normocytic, normochromic anaemia. Over the next 6 weeks her symptoms deteriorated, and she became unresponsive to stimuli. A new MRI scan showed progression of the white matter lesions. The neurologist requested plasma homocysteine (Hcys) which was more than 8 times the upper limit of normal. Further testing revealed increased methylmalonic acid and the patient was diagnosed with adult-onset cobalamin C deficiency. This case illustrates that Hcys and/or methylmalonic acid should be determined in patients presenting with neuropsychiatric symptoms suggestive of vitamin B12 deficiency with a normal serum vitamin B12 to rule out a late-onset cobalamin C deficiency.     

美国在网络主权问题上的立场变化及启示

[目的/意义]在网络空间这个新颖而又无处不在的领域中,主权原则如何运作一直是国家实践和学界理论研究中的硬核问题。厘清美国在该问题上的立场变化对我国参与网络空间国际治理具有积极意义。[方法/过程]利用历史分析法、文献研究法和对比分析法对美国《情报活动中的国际法律问题评估》(1999年)、《网络行动国际法塔林手册2.0》和《在军事行动中使用网络能力的国际法框架》(2017年)进行法律考察。[结果/结论]研究表明,为应对美国在网络主权问题上的立场转变,我国应坚持领土主权原则的拘束力,平等地尊重各国网络主权,并积极参与网络空间国际规则制定的实践,推动网络空间命运共同体理念的国际法构建。     

英美两项高等教育系统职能分化政策的比较分析

美国加州的"三重制"和英国的"双重制",都是产生于20世纪60年代的高教系统职能分化政策。通过比较分析可以看出:政策环境的差异在很大程度上影响了它们的发展方向,政策的合法性程度是决定它们运行稳定与否的关键。     

关于企业铁路C62A型号货车增载的可行性探讨

随着国民经济的发展,铁路车辆的需求矛盾日益突出,从增加运输能力的角度考虑,对现有的车辆进行增载是一个投资少、见效快的途径,根据企业铁路目前使用的C62A型车辆的主要技术参数及状况,从垂直动载荷及技术指标分析,在标记载重60t的基础上增重5t是可行的,并能产生较大的经济效益,可以在企业铁路上进行推广。

News or Noise?

This study investigates the quality of the U.S. News annual ranking of national universities and liberal arts colleges. The main finding is that current rankings changes have a strong tendency to revert over the following two rankings. Using a simple model, this study estimates that about 70 to 80 percent of the variation in rankings changes is transitory and reversible. Thus, most of the news in the annual rankings is essentially meaningless noise. An analysis of possible explanations suggests that the noise in annual ranking changes is most likely due to various measurement, estimation, and other information processing errors in the rankings' underlying components.
