The study suggests that using other healthcare professionals to take blood pressure readings could help red...
A study of nearly 300,000 adults found that adding glycated hemoglobin (HbA1c) information to conventional cardiovascular risk factors had little impact on predicting cardiovascular disease risk. Higher HbA1c levels were previously associated with increased CVD incidence, but this analysis did not find clinically meaningful improvement.

The study reveals a strong relationship between item frequency and detection rates, highlighting how rare objects can slip past us despite intense searching.
A new analysis suggests that economic development can only buy happiness up to a certain level of wealth. Once income reaches around $36,000 GDP per capita, life satisfaction levels peak before dipping slightly in the very rich countries. This finding contradicts previous studies that showed a flat relationship between GDP and happiness.
Researchers in Denmark investigated oral fluoroquinolone use and found no association with an increased risk of retinal detachment. The study analyzed data from a nationwide register and compared fluoroquinolone use to nonuse, concluding that current use would account for only 11 additional cases per 1,000,000 treatment episodes.
The NHS 111 service increased emergency ambulance calls, attendances at emergency care departments, and use of urgent care services during its first year of operation. Despite being designed to direct patients to the most appropriate level of care, NHS 111 did not reduce these pressures.
