This week Dr Ray O’Connor considers some recent papers which touch on disease prevention Vaccine preventable Community Acquired Pneumonia (CAP)This was a prospective, population-based CAP surveillance study1 at three hospitals in Germany. All patients admitted with clinically suspected CAP were tested for vaccine preventable infections. These included streptococcus pneumoniae, respiratory syncytial virus (RSV), influenza virus … Read more
Research suggests that caffeine may help restore social memory impaired by sleep deprivation by acting on one specific brain circuit that is impacted by disrupted rest. The finding offers insight into how sleep loss affects memory-related brain pathways and could inform future dietary strategies to address cognitive impairment. Researchers at the Yong Loo Lin School … Read more
Drinking 2 to 4 cups of coffee a day was linked to a modest reduction in heart failure risk in this updated meta-analysis, with the lowest estimated risk at 1 to 2 cups and the strongest message being moderation, not excess. Key takeaways Drinking 2 to 4 cups of coffee a day was associated with … Read more

In one of the largest prospective cohort studies to date, moderate consumption of caffeinated coffee (2-3 cups a day) or tea (1-2 cups a day) correlated with reduced dementia risk and modest improvements in cognitive function, although decaffeinated coffee showed no protective effect. Zhang et al. determined that moderate caffeinated coffee and tea intake can … Read more

Coffee can help you stay awake, but what does caffeine actually do to your brain once you’re asleep? Using AI, a team of researchers has an answer: it affects the brain’s ‘criticality’. The effects of caffeine on brain dynamics were significantly more pronounced in young adults than middle-aged participants.(Pixabay) In a study published in April … Read more
Summary: A new study reveals that caffeine increases the complexity of brain activity during sleep, especially in younger adults, potentially disrupting the brain’s ability to recover overnight. Researchers used EEG and AI to analyze sleep in 40 adults after caffeine or placebo intake, identifying less predictable brain signals and increased wake-like brainwave patterns. Caffeine altered … Read more
