IMMUNE REACTION: An overactive immune system could trigger the debilitating condition chronic fatigue syndrome (CFS), a study has found. CFS — also known as ME (myalgic encephalomyelitis) — is a long-term illness characterised by extreme tiredness. The underlying biology of the condition has remained a mystery, although many patients report their illness starting following an infection such as a viral illness. Scientists at King’s College London have found that an immune system overreacting to an infection could help explain how the condition is contracted. Lead researcher Dr Alice Russell said: “Our findings suggest that people who have an exaggerated immune response to a trigger may be more at risk of developing CFS.” CERVICAL TEST: A new test for cervical cancer that could “revolutionise screening” has been found to outperform current tests at a reduced cost, according to a study. The “epigenetics-based” test detected 100% of the cancers that developed in 15,744 women in a screening trial led by Queen Mary University of London. It performed “significantly better” than the Pap smear or human papillomavirus (HPV) test, and the study’s authors believe it would be cheaper if fully rolled out. The Pap smear detected one quarter, while the HPV test detected half of the cancers in the group of women aged 25-65 in Canada. The study was published in the International Journal of Cancer. SILENT DISCO: People attending festive parties have been urged to wear earplugs to protect their hearing while in noisy pubs, bars, or concerts. Revellers should also avoid standing for too long near speakers and take breaks from the noise. Exposure to loud noise can lead to tinnitus, often described as ringing in the ears . Loud noise exposure can damage the hair cells in the cochlea, leading to hearing loss and tinnitus. Symptoms of the condition can last anywhere from a few hours to permanent damage.
