Sustainable photocatalytic degradation of antibiotic norfloxacin using microfibrillated cellulose@ZnO nanocomposites.

Antibiotics from the fluoroquinolone class, such as norfloxacin (NOR), are emerging contaminants with significant environmental and human health impacts. Their safe degradation from water remains a global challenge due to their persistence, lack of biodegradability, and ability to induce resistant bacteria. To the best of our knowledge, for the first time, this work reports the development of highly efficient photocatalytic degradation of NOR using environmentally friendly microfibrillated cellulose@ZnO (MFC@ZnO) photocatalysts.

Cardiac autonomic responses to high-intensity kettlebell training in untrained young women: A pilot study.

Background: and purpose: The autonomic recovery after exercise provides information about the cardiovascular overload employed during the training session. The autonomic response over a training course is unclear in exercises performed at high intensities, such as kettlebell training. The study aimed to characterize the cardiac autonomic modulation after exercise in three distinct phases of a high-intensity kettlebell training program in young women.

Effect of a driving pressure-limiting strategy for patients with acute respiratory distress syndrome secondary to community-acquired pneumonia: the STAMINA randomised clinical trial.

Background: This study aimed to assess whether a driving pressure-limiting strategy based on positive end-expiratory pressure (PEEP) titration according to best respiratory system compliance and tidal volume adjustment increases the number of ventilator-free days within 28 days in patients with moderate to severe acute respiratory distress syndrome (ARDS).

Methods: This is a multi-centre, randomised trial, enrolling adults with moderate to severe ARDS secondary to community-acquired pneumonia. Patients were randomised to a driving pressure-limiting strategy or low PEEP strategy based on a PEEP:FiO table.

The global issue of metal contamination in sharks, rays and skates and associated human health risks.

Elasmobranchs, including sharks, rays, and skates, are a global protein source but face threats from overfishing and population declines. Despite their lower market value, increased consumption raises sustainability and public health concerns. Commonly landed species like the Blue Shark, Shortfin Mako, and Spiny Dogfish are particularly vulnerable to bioaccumulation of metals such as mercury (Hg), lead (Pb), cadmium (Cd), and arsenic (As), posing health risks to consumers.

Two Years Post-COVID-19: An Ecologic Study Evaluating the Impact on Brazil's Mammographic Screening Program.

Objectives: The objective of this study was to assess the impact of the COVID-19 pandemic, after 2 years, on mammographic screening in Brazil evaluating BIRADS® results, breast cancer diagnosis rates, and breast cancer stage.

Study Design: This was an ecological observational study based on retrospective data from Brazil's mammographic screening program from 2015 to 2023.

Methods: Data were obtained from the national screening database DATASUS - SISCAN (Cancer System Information) and retrieved in March 2024.
