Cardiomyopathy Secondary to Thyroid and Parathyroid Dysfunction: Case Report and Literature Review
Heart failure due to metabolic derangements is not common in clinical practice. However, outcome is usually positive given that the precipitating factor is recognized and treatment is initiated in a timely fashion. We report an unusual case of reduced left ventricular systolic function as a result of hypocalcemia and long standing untreated primary hypothyroidism in a patient without structural heart disease. Delay in seeking appropriate medical attention for both disorders has culminated in cardiac dysfunction that was favorably altered with correction of underlying etiologies. Therefore, early recognition and expedient management of hypocalcemia and hypothyroidism can result in an imminent improvement of cardiac function

Futures trading, spot price volatility and market efficiency: evidence from European real estate securities futures
In 2007 futures contracts were introduced based upon the listed real estate market in Europe. Following their launch they have received increasing attention from property investors, however, few studies have considered the impact their introduction has had. This study considers two key elements. Firstly, a traditional Generalized Autoregressive Conditional Heteroskedasticity (GARCH) model, the approach of Bessembinder & Seguin (1992) and the Gray’s (1996) Markov-switching-GARCH model are used to examine the impact of futures trading on the European real estate securities market. The results show that futures trading did not destabilize the underlying listed market. Importantly, the results also reveal that the introduction of a futures market has improved the speed and quality of information flowing to the spot market. Secondly, we assess the hedging effectiveness of the contracts using two alternative strategies (naïve and Ordinary Least Squares models). The empirical results also show that the contracts are effective hedging instruments, leading to a reduction in risk of 64 %
