Highlights From the Annual Meeting of the American Epilepsy Society 2022
With more than 6000 attendees between in-person and virtual offerings, the American Epilepsy Society Meeting 2022 in Nashville, felt as busy as in prepandemic times. An ever-growing number of physicians, scientists, and allied health professionals gathered to learn a variety of topics about epilepsy. The program was carefully tailored to meet the needs of professionals with different interests and career stages. This article summarizes the different symposia presented at the meeting. Basic science lectures addressed the primary elements of seizure generation and pathophysiology of epilepsy in different disease states. Scientists congregated to learn about anti-seizure medications, mechanisms of action, and new tools to treat epilepsy including surgery and neurostimulation. Some symposia were also dedicated to discuss epilepsy comorbidities and practical issues regarding epilepsy care. An increasing number of patient advocates discussing their stories were intertwined within scientific activities. Many smaller group sessions targeted more specific topics to encourage member participation, including Special Interest Groups, Investigator, and Skills Workshops. Special lectures included the renown Hoyer and Lombroso, an ILAE/IBE joint session, a spotlight on the impact of Dobbs v. Jackson on reproductive health in epilepsy, and a joint session with the NAEC on coding and reimbursement policies. The hot topics symposium was focused on traumatic brain injury and post-traumatic epilepsy. A balanced collaboration with the industry allowed presentations of the latest pharmaceutical and engineering advances in satellite symposia
Effect of biosolids from municipal sewage sludge composted with rice husk on soil functionality
Two different biosolids were obtained composting
anaerobic (A) and aerobic (B) municipal sewage sludge
(SS) with rice husk. Higher amounts of SS (1:1 v/v) could be
used in this composting process than in conventional ones.
The two biosolids were characterized by chemical analysis
and compared with a conventional green manure plus municipal
solid waste and municipal SS compost. The effect of
these products on soil functionality was studied in a 14-
week incubation experiment by their addition to two
different soils (silty clay—Ustic Endoaquert—and sandy
loam—Aquic Xeropsamment). The total organic C
ranged from 20 to 26 % and total N from 1.6 to
2.5 % in the two biosolids. The most relevant difference
was due to dissolved organic C that was lower in the
anaerobic biosolid (1 mgCkg−1) than in the other products
(5–6 mgCkg−1). The total trace elements (Cd, Cr,
Cu, Ni, Pb and Zn) contents were under the limits fixed
by the European legislation for soil application of SS
(EC Directive 86/278/EEC, 1986). The three biosolids
did not show strong negative effects on soil functionality
during the incubation experiment, although some
significant differences were found. The aerobic biosolid
B mainly increased cumulative N release, microbial
activity, basal respiration rate, microbial biomass-C-tototal
organic C ratio, β-glucosidase, alkaline phosphomonoesterase
and aryl-sulphatase activities. The anaerobic
one (B) decreased basal respiration rate, microbial
biomass-C-to-total organic C ratio and aryl-sulphatase
activity. DTPA soil bioavailable heavy metals were not
affected by biosolids additions
