The study suggests a fundamental difference in brain responses between genders, which may lead to the development of more effective and non-addictive pain treatments for women.
A clinical trial revealed that regular aspirin was as effective as sibrafiban in preventing blood clots, while high-dose sibrafiban showed increased risk of death and second heart attacks. Aspirin's minimal risks make it a hard-to-beat option.
A new study reveals that sleep disruption is a primary reason older adults with arthritis seek medical care, outweighing other symptoms like reduced mobility. The research suggests addressing sleep issues can be crucial in managing arthritis, particularly for those who may not connect their pain with sleep disruptions.
A study found that top hospitals in the US are falling short in stroke prevention, with 40% of patients not receiving necessary clot-preventing medications. The study, which analyzed data from 961 patients, also showed that certain groups, such as older adults and those with major heart disease, were more likely to receive treatment.
