This paper presented the preparation, characterization, and adsorption properties of Brazil nut shell activated carbon for catechol removal from aqueous solutions. The equilibrium adsorption of catechol molecules on this activated was experimentally quantified at pH 6 and temperatures ranging from 25 to 55 °C, and at 25 °C and pH ranging from 6 to 10. These results were utilized to elucidate the role of surface functionalities through statistical physics calculations.

Objective: To examine the association between baseline multisite pain (two and three or more sites) and longitudinal risk of fall and recurrent falls among older adults with or at risk of knee osteoarthritis (OA).

Design: This prospective longitudinal cohort study included older adults with or at risk of knee OA. Fall, including the history of falls, number of falls, and recurrent falls, were assessed at baseline and during six follow-up visits at 12, 24, 36, 48, 72, and 96 months.

Article Synopsis
  • - Dexmedetomidine (DEX) is a sedative used for critically ill COVID-19 patients due to its benefits like reduced respiratory depression and potential anti-inflammatory effects, prompting a study on its safety and efficacy in this context.
  • - In a study involving 155 ICU patients with COVID-19 who did not need invasive ventilation, DEX did not significantly reduce the incidence of respiratory failure, but those receiving DEX had a statistically shorter time until they required mechanical ventilation.
  • - Outcomes related to ICU and hospital stays, as well as mortality rates within 30 days, showed no significant differences between DEX users and the control group, indicating the need for further studies to explore DEX's effects.
