Inductive Characterization of ENDS-Associated Adverse Events Among California Young Adults.

Introduction: Previous studies have identified numerous adverse events experienced with the use of ENDS or E-cigarettes. However, much remains unknown about adverse event frequency, duration, and response experienced by users. The purpose of this study was to inductively characterize ENDS-attributed adverse events among young adults.

Health professionals' preferences with the use of pegfilgrastim on-body injector at oncology centers in 8 cities in Colombia.

Background: Febrile neutropenia associated with some chemotherapy regimens can lead to potentially fatal complications and high health care costs. Administration of pegfilgrastim using an On-Body Injector (OBI) may be more convenient for cancer patients and physicians in countries with limited access to high-complexity healthcare. This study aims to describe physician and nurse preferences regarding different options for administration of pegfilgrastim at cancer centers, the chemotherapy schemes for which pegfilgrastim is most frequently prescribed and how healthcare providers prioritize certain administration schemes according to patients' access to healthcare services.

Variables Affecting Delignification of Corn Wastes Using Urea for Total Reducing Sugars Production.

In this work, a combination of mechanical and chemical pretreatments using urea on corn residues (leaves and stems) was evaluated to obtain total reducing sugars (TRSs). The residues were characterized via high-performance liquid chromatography (HPLC) to quantify biomass composition. During the mechanical pretreatment, the particle size of the biomass was reduced to 0.

Environmental and Safety Assessments of Industrial Production of Levulinic Acid via Acid-Catalyzed Dehydration.

These days, there is a need to develop novel and emerging processing pathways that permit production of value-added substances and fuels considering sustainability aspects. In this sense, levulinic acid (LA) is one of the most promising biorefinery products. This paper presents environmental and safety assessments of LA production via acid-catalyzed dehydration (ACD) of biomass.
