Medium‐Chain Acyl‐CoA Dehydrogenase Deficiency in Adulthood: A Potential Diagnosis in a Patient with Mental Status Changes Suspected of Drug Toxicity

Medium‐chain acyl‐CoA dehydrogenase (MCAD) deficiency is a rare but important component of the differential diagnosis for adults with a history of premortem mental status changes and the postmortem finding of hepatic steatosis. This case report describes a 30‐year‐old white man who, following a period of nausea and vomiting, was admitted to the hospital with sudden mental status deterioration followed rapidly by clinical deterioration and death. Treating physicians in this case suspected acute illicit drug toxicity with synthetic cathinones based on social history. Clinicians and medical examiners should be aware that the presentation, signs, and symptoms described may indicate an underlying inborn error of metabolism such as MCAD deficiency and take action accordingly.     

The Use of Tooth Crown Measurements in the Assessment of Ancestry

As the hardest tissue in the body, teeth have the potential to offer a wealth of biological information to the forensic anthropologist, which can include the assessment of ancestry. Using a large data set of dental measurements, the efficacy of mesiodistal and buccolingual tooth dimensions to discriminate between broad, geographically based groups is explored. A general pattern is identified: African populations have the largest teeth, Asians possess teeth of intermediate size, and Europeans have the smallest teeth. In a discriminant function analysis using crown measurements of all teeth (mandibular and maxillary and excluding the third molar), individuals were correctly classified in 71.3% of cases. When the sex of the individual is known, classification is improved up to 88.1% in females and 71.9% of males (cross‐validated). Based on these results, we argue that dental metrics can be regularly employed as part of the development of the biological profile.     

Information Transmission Among World Major Gold Futures Markets： Evidence From High Frequency Synchronous Trading Data

This study examines the international information transmission among three major gold futures markets namely New York Mercantile Exchange in division of Commodity Exchange （COMEX）, Multi Commodity Exchange （MCX）, and Tokyo Commodity Exchange （TOCOM）. The main concept of this research is no matter where gold futures traded, they share the same underlying asset. Two well-documented approaches, which are vector error correction model and information share, are utilized to measure the process of price discovery under this trivariate system. The uniqueness of this study is that it employs synchronous intraday time series which can mitigate the stale price problem from daily observations. The evidences indicate that the three gold futures prices are cointegrated and driven by the same fundamental factors. New arrival information disseminates efficiently among the three markets and the pricing information transmission among exchanges is very rapid. However, the lead-lag relationship among markets still exists with the dominance of COMEX gold futures as the centre of price discovery The US gold futures market is the most efficient in processing information. Its role on price discovery and information can be attributed to COMEX＇s massive trading volume.
