Accessibility of polycyclic aromatic hydrocarbon content in fishes from the region of the 2019 oil spill on the northeast Brazil coast.

In August 2019, Brazil experienced its largest large oil spill, which impacted extensive areas and significantly affected the northeastern region, particularly Pernambuco. Polycyclic aromatic hydrocarbons (PAHs), major oil components, are critical for assessing fish contamination risks. This study presents two sample pretreatment methods for fish samples - ultrasound-enhanced air-assisted liquid-liquid microextraction (UE-AA-LLME) for low molar mass PAHs, and matrix solid-phase dispersion for high molar mass PAHs - followed by a Gas-Chromatography coupled to Mass Spectrometry (GC-MS) detection.

Effective Nitrate Electroconversion to Ammonia Using an Entangled CoO/Graphene Nanoribbon Catalyst.

There has been huge interest among chemical scientists in the electrochemical reduction of nitrate (NO) to ammonia (NH) due to the useful application of NH in nitrogen fertilizers and fuel. To conduct such a complex reduction reaction, which involves eight electrons and eight protons, one needs to develop high-performance (and stable) electrocatalysts that favor the formation of reaction intermediates that are selective toward ammonia production. In the present study, we developed and applied CoO/graphene nanoribbon (GNR) electrocatalysts with excellent properties for the effective reduction of NO to NH, where NH yield rate of 42.

A 7-point evidence-based care discharge protocol for patients hospitalized for exacerbation of COPD: consensus strategy and expert recommendation.

Acute exacerbations of COPD (ECOPD) are an important event in the life of a COPD patient as it causes significant deterioration of physical, mental, and social health, hastens disease progression, increases the risk of dying and causes a huge economic loss. Preventing ECOPD is therefore one of the most important goals in the management of COPD. Before the patient is discharged after hospitalization for ECOPD, it is crucial to offer an evidence-based care bundle protocol that will help minimize the future risk of readmissions and death.

Comparison between 2- and 4-plate fixation in Le Fort I osteotomy: a mixed methods systematic review.

Objective: Achieving postsurgical skeletal stability is crucial for successful outcomes and patient satisfaction. Precision maxillofacial surgery, which integrates precision techniques with minimally invasive approaches, is increasingly recognized for its potential to enhance long-term stability and reduce surgical risks and complications. This study aimed to comprehensively evaluate the impact of fixation techniques (2 vs 4 plates) during Le Fort I osteotomy in orthognathic surgery on skeletal stability.

Characterization of notifications of violence against women living in rural contexts in Brazil from 2011 to 2020.

Objective: To describe and analyze notifications and the temporal trend of violence against women living in rural contexts in Brazil, from 2011 to 2020.

Methods: Ecological time-series study of a descriptive and analytical nature, with data from the Notifiable Diseases Information System on violence against women aged 18 to 59 years, in rural areas, from 2011 to 2020, in Brazil. The analyses were descriptive and trend-related, with the regression model using inflection points (joinpoint) and calculation of the annual percent change (APC) and the average annual percent change (AAPC).
