RESUMO
Cyanobacterial algal hepatotoxins, called microcystins (MCs), are a global health concern, necessitating research on effective removal methods from contaminated water bodies. In this study, we synthesized non-fluorine MIL-100(Fe) using an environmentally friendly room-temperature method and utilized it as an adsorbent to effectively remove microcystin-LR (MC-LR), which is the most toxic MC congener. MIL-100(Fe) was thoroughly characterized, and its adsorption process was investigated under various conditions. Results revealed rapid MC-LR adsorption, achieving 93% removal in just 5 min, with the pseudo-second-order kinetic model indicating chemisorption as the primary mechanism. The Langmuir isotherm model demonstrated a monolayer sorption capacity of 232.6 µg g-1 at room temperature, showing favorable adsorption. Furthermore, the adsorption capacity increased from 183 µg g-1 at 20 °C to 311 µg g-1 at 40 °C, indicating an endothermic process. Thermodynamic parameters supported MC-LR adsorption's spontaneous and feasible nature onto MIL-100(Fe). This study highlights MIL-100(Fe) as a promising method for effectively removing harmful biological pollutants, such as MC-LR, from contaminated water bodies in an environmentally friendly manner.

The occupational well-being of healthcare providers is crucial for safe and effective patient care, especially in the complex, high acuity operating room (OR) setting. There has been a recent proliferation of interventions to improve teamwork in the OR setting, but the impact of these interventions on clinician occupational well-being has yet to be systematically assessed. This systematic review aimed to summarize the impact of interprofessional teamwork interventions on occupational well-being among perioperative healthcare providers. We included all qualitative or quantitative peer-reviewed studies assessing a multidisciplinary teamwork intervention including members of at least two professions. We included seven studies which involved checklists (n = 2), simulation-based training (n = 2), and various teamwork development and training programs (n = 3). Five of the seven included studies reported no significant effect on job satisfaction, while one found a significant negative association between the intervention and job satisfaction (p < .0001), and another showed significant decrease in worker stress. Our findings highlight the gaps in our understanding of the impact of interprofessional teamwork interventions on healthcare worker well-being in the perioperative environment and the multi-level factors influencing OR teamwork, intervention implementation, and well-being across the different professions.
