Differences in cognitive decline between men, women

A pooled analysis of five studies reveals significant differences in cognitive decline between men and women, with women experiencing a more rapid decline. The study suggests that women's brains may be more susceptible to age-related cognitive changes, with potential implications for gender-specific interventions.

Showcasing the green construction sites of tomorrow

A new project, Future Green Construction Sites, is being launched in Denmark to demonstrate elements of a green construction site of the future. The project involves experts from six companies and researchers from Aarhus University, who will test various climate-friendly initiatives to promote a green transition for construction sites.

Guideline for reducing opioid use post-surgery leads to high pain management satisfaction

A new guideline for reducing opioid use post-surgery has led to a high pain management satisfaction rate of over 90%, with 83% of patients properly disposing of unused pills. The guideline takes into account individual patients' perception of pain, setting expectations and prescribing non-opioid analgesics to minimize opioid use.

Computer training to reduce trauma symptoms

Researchers from Ruhr-University Bochum found that computerised training can reduce PTSD symptoms by helping patients reappraise trauma memories. Patients who underwent the 'Cognitive Bias Modification-Appraisal' training showed fewer trauma-relevant symptoms and lower stress hormone levels compared to those in a control group.

Lethal house lures reduce incidence of malaria in children

Researchers found that installing window screening and insecticide-laced screens under eaves can significantly reduce clinical malaria incidence among children. The intervention, called In2Care EaveTube, was effective in areas with highly resistant mosquitoes, with a 38% overall reduction in malaria incidence.
