Fatal Hypermagnesemia in Patients Taking Magnesium Hydroxide.

Hypermagnesemia is a rare but potentially fatal electrolyte disorder often overlooked because of its unfamiliarity. Magnesium is regulated through a balance of bone, intestinal absorption, and renal excretion. Hypermagnesemia typically arises from excessive magnesium intake or reduced renal excretion; however, it also occurs in patients with normal kidney function.

Startup of Demo-Scale Anaerobic Digestion Plant Treating Food Waste Leachate: Process Instability and Recovery.

A demo-scale (600 m3 working volume) anaerobic digester treating food waste leachate was monitored during its startup period. The operation strategy was adjusted twice (i.e.

Environmental Risk and Credit Ratings, and the Moderating Effect of Market Competition.

This study examines the relationship between environmental risk and corporate bond credit ratings, and the moderating effect of market competition. We focus on Korean firms that are facing increasing risk of environmental crisis after the COVID-19 pandemic. Recently, the Korean government has been controlling businesses while promoting policies to transform the economy into a low-energy, low-carbon economy.

Real-world evidence of levofloxacin prophylaxis in elderly patients with newly diagnosed multiple myeloma who received bortezomib, melphalan, and prednisone regimen.

Background: Although survival outcomes of multiple myeloma (MM) have improved with the development of new and effective agents, infection remains the major cause of morbidity and mortality. Here, we evaluated the efficacy of levofloxacin prophylaxis (in a real-world setting) during bortezomib, melphalan, and prednisone (VMP) therapy in elderly patients with newly diagnosed MM.

Methods: This study retrospectively analyzed the records of patients with newly diagnosed MM treated with the VMP regimen between February 2011 and September 2020 at three institutes of the Republic of Korea.

Shift in methanogenic community in protein degradation using different inocula.

Anaerobic digestion (AD) of protein-rich wastes is problematic due to production of ammonia and hydrogen sulfide. In this work, eight inocula were used in batch AD of solutions of gelatin and gluten at 3 g COD substrate/1g VSS inoculum. AD plants from which inocula originated were treating food waste or food wastewater, wastewater sludge, or a combination of them.

Shift in bacterial diversity in acidogenesis of gelatin and gluten seeded with various anaerobic digester inocula.

The aim of this study was to investigate divergence of bacteria degrading model proteins of food-processing wastewater. Gelatin and gluten were used as substrate to represent animal and plant proteins from food wastes, respectively. The inocula were obtained from eight full-scale anaerobic digestion reactors.
