Mechanism of biochar composite (BNZBC) activated peracetic acid for efficient antibiotic degradation: Synergistic effect between free radicals and non-free radicals.

This study utilized corn straw as the feedstock to synthesize biochar (BC) loaded with cobalt-zeolitic imidazolate framework nanoparticles and boron nitride quantum dots. The prepared BC composite, named BNZBC, efficiently activated peracetic acid (PAA), resulting in the degradation of 94.8% of sulfadiazine (SDZ) in five minutes.

Simultaneous removal of sulfamethoxazole during fermentative production of short-chain fatty acids.

This study explores the simultaneous sulfamethoxazole (SMX) removal and short-chain fatty acids (SCFAs) production by a Clostridium sensu stricto-dominated microbial consortium. SMX is a commonly prescribed and persistent antimicrobial agent frequently detected in aquatic environments, while the prevalence of antibiotic-resistant genes limits the biological removal of SMX. Under strictly anaerobic conditions, sequencing batch cultivation coupled with co-metabolism resulted in the production of butyric acid, valeric acid, succinic acid, and caproic acid.

Integration of microalgae cultivation and anaerobic co-digestion with dairy wastewater to enhance bioenergy and biochemicals production.

A sequential anaerobic digestion and phycoremediation process was employed to recover nutrients and remove pollutants from dairy wastewater (DW), while simultaneously producing biomethane and biochemicals. Anaerobic digestion of 100% DW achieved a methane content and production rate of 53.7% and 0.

Antibiotic sulfadiazine degradation by persulfate oxidation: Intermediates dependence of ecotoxicity and the induction of antibiotic resistance genes.

To preserve the water resources, this study has analyzed the ecotoxicity and antibiotic resistance genes (ARGs) induction capacity of sulfadiazine degradation intermediates resulting from persulfate activation oxidation enhanced by ultraviolet, ultrasound and microwave. The five degradation pathways caused by the contribution discrepancy of electron transfer and singlet oxygen (O) and variations in the ecotoxicity of different degradation products were analyzed. Microcosm experiment exhibited that the microbial community in actual water changed significantly with SDZ and degradation intermediates, in which the dominant genera were Aeromonas, Cupriavidus, Elizabethkingia and Achromobacter.

High-cell-density heterotrophic cultivation of microalga Chlorella sorokiniana FZU60 for achieving ultra-high lutein production efficiency.

Chlorella sorokiniana has received particular attention as a promising candidate for microalgal biomass and lutein production. In this work, heterotrophic cultivation was explored to improve the lutein production efficiency of a lutein-rich microalga C. sorokiniana FZU60.

Enhanced sulfonamides removal via microalgae-bacteria consortium via co-substrate supplementation.

Both co-cultivation and co-substrate addition strategies have exhibited massive potential in microalgae-based antibiotic bioremediation. In this study, glucose and sodium acetate were employed as co-substrate in the cultivation of microalgae-bacteria consortium for enhanced sulfadiazine (SDZ) and sulfamethoxazole (SMX) removal. Glucose demonstrated a two-fold increase in biomass production with a maximum specific growth rate of 0.

Lutein production by microalgae using corn starch wastewater pretreated with rapid enzymatic hydrolysis.

The main purpose of this study was to explore the pretreatment process of corn starch wastewater (CSW) and engineered microalgae cultivation strategy to improve the nutrient recovery from wastewater and the yield of microalgae lutein. One-stage enzymatic hydrolysis utilizing α-amylase and glucoamylase simultaneously was established to efficiently harvest a maximum concentration of reducing sugar content of 7.26 g/L from CSW in 50 min.

Reporting of Perioperative Adverse Events by Pediatric Anesthesiologists at a Tertiary Children's Hospital: Targeted Interventions to Increase the Rate of Reporting.

Background: Incident reporting systems (IRSs) are important patient safety tools for identifying risks and opportunities for improvement. A major IRS limitation is underreporting of incidents. Perioperative anesthesia IRSs have been established at multiple pediatric institutions and a national pediatric anesthesia IRS for perioperative serious adverse events (SAEs) is maintained by Wake Up Safe (WUS), a patient safety organization dedicated to pediatric anesthesia quality improvement.

Implementation of a standardized postanesthesia care handoff increases information transfer without increasing handoff duration.

Background: In the transition of a patient from the operating room (OR) to the postanesthesia care unit (PACU), it was hypothesized that (1) standardizing the members of sending and receiving teams and (2) requiring a structured handoff process would increase the overall amount of patient information transferred in the OR-to-PACU handoff process.

Methods: A prospective cohort study was conducted at a 311-bed freestanding academic pediatric hospital in Northern California. The intervention, which was conducted in February-March 2013, consisted of (1) requiring the sending team to include a surgeon, an anesthesiologist, and a circulating nurse, and the receiving team to include the PACU nurse; (2) standardizing the content of the handoff on the basis of literature-guided recommendations; and (3) presenting the handoff verbally in the I-PASS format.

Variability of characteristics and outcomes following cardiopulmonary resuscitation events in diverse ICU settings in a single, tertiary care children's hospital*.

Objective: The primary objective of this study was to compare and contrast the characteristics and survival outcomes of cardiopulmonary resuscitation for "monitored" events in pediatric patients treated with chest compressions more than or equal to 1 minute in varied ICU settings.

Design: Retrospective observational study.

Setting: Three different specialized ICUs in a single, tertiary care, academic children's hospital.

Improving code team performance and survival outcomes: implementation of pediatric resuscitation team training.

Objective: To determine whether implementation of Composite Resuscitation Team Training is associated with improvement in survival to discharge and code team performance after pediatric in-hospital cardiopulmonary arrest.

Design, Setting, And Subjects: We conducted a prospective observational study with historical controls at a 302-bed, quaternary care, academic children's hospital. Inpatients who experienced cardiopulmonary arrest between January 1, 2006, and December 31, 2009, were included in the control group (123 patients experienced 183 cardiopulmonary arrests) and between July 1, 2010, and June 30, 2011, were included in the intervention group (46 patients experienced 65 cardiopulmonary arrests).

Nursing mortality and morbidity and journal club cycles: paving the way for nursing autonomy, patient safety, and evidence-based practice.

The ability to perform professional scrutiny is a required component of autonomous practice, and the ability to use science to guide care delivery is a hallmark of professional practice. The cardiovascular intensive care unit staff initiated a forum for peer review to encourage the use of the best available evidence to guide system and practice changes. A focus group was formed, resulting in development and implementation of a specific process for regular cycles of nursing mortality and morbidity (M & M) conferences, a journal club, and interdisciplinary educational sessions in staff meetings.

Effect of a rapid response team on hospital-wide mortality and code rates outside the ICU in a Children's Hospital.

Context: Introduction of a rapid response team (RRT) has been shown to decrease mortality and cardiopulmonary arrests outside of the intensive care unit (ICU) in adult inpatients. No published studies to date show significant reductions in mortality or cardiopulmonary arrests in pediatric inpatients.

Objective: To determine the effect on hospital-wide mortality rates and code rates outside of the ICU setting after RRT implementation at an academic children's hospital.
