Drug-induced LQTS is a significant concern and has resulted in drug withdrawals from the market in the past.

Clinical and laboratory findings and etiologies of genetic homocystinemia: a single-center experience.

Background: Homocysteine (Hcy) is an endogenous nonprotein sulfur-containing amino acid biosynthesized from methionine by the removal of its terminal methyl group. Hyperhomocysteinemia (HHcy) has been linked to many systemic disorders, including stroke, proteinuria, epilepsy, psychosis, diabetes, lung disease, and liver disease. The clinical effects of high serum Hcy level, also known as hyperhomocysteinemia, have been explained by different mechanisms.

Background: Neuromyelitis optica spectrum disorders (NMOSD) are immune-mediated inflammatory disorders of the central nervous system (CNS) mostly presenting as optic neuritis and acute myelitis. NMOSD can be associated with seropositivity for aquaporin 4 antibody (AQP4 IgG), myelin oligodendrocyte glycoprotein antibody (MOG IgG), or can be seronegative for both. In this study, we retrospectively examined our seropositive and seronegative pediatric NMOSD patients.

ESG investing and the financial performance: a panel data analysis of developed REIT markets.

This study investigates the empirical link between the social and financial performance of the Real Estate Investment Trusts (REITs) by utilizing the PVAR-Granger causality model and a fixed-effects panel data model with a rich dataset comprising 234 ESG-rated REITs across five developed economies from 2003 to 2019. The results suggest that investors pay attention to individual E/S/G metrics and price each component of ESG investing differently, with E-investing and S-investing practices being the significant financial performance factors of REITs. This study is the first attempt to test the social impact and risk mitigation hypotheses of the stakeholder theory of the corporation and the neoclassic trade-off argument to explore the association between corporate social responsibility and the market valuation of REITs.
