When your immune system meddles in your love life
About a decade ago, evolutionary psychologists suggested that humans have evolved a first line of defense against disease: a behavioural immune system (BIS). This system is thought to be unconsciously activated, to varying degrees, when an individual perceives, rightly or wrongly, that there is a…
Childhood Measles Linked to Increased Risk of Later Lung Disease
In a new Respirology study, having measles—a highly contagious respiratory infection—during early childhood was linked with an increased risk of developing chronic obstructive pulmonary disease in middle age, but only in adults with asthma and a considerable history of smoking.
Re-Introducing an ‘Old’ Antibiotic May Help Fight Multi-Drug Resistant Bacteria
A new study indicates that the drug fosfomycin may be effective for treating multidrug-resistant bacterial infections. In most European countries, the oral formulation is only approved as a 3 gram single dose for the treatment of uncomplicated cystitis; however the Pharmacology Research & Perspectives study…
Three or More Cups of Coffee Daily Halves Mortality Risk in Patients with Both HIV and HCV
Novel five-year study highlights importance of behaviors such as coffee drinking and not smoking on health and survival of HIV-infected patients, report investigators in the Journal of Hepatology
Chikungunya virus infection in Italy
The European Centre for Disease Prevention and Control issued a risk assessment on the ongoing outbreak of chikungunya virus infection in Italy. Two related clusters of autochthonous transmission of chikungunya virus have been detected in Italy in the city of Anzio and in Rome, two…
Nurses’ regular use of disinfectants is associated with developing COPD
Regular use of disinfectants is linked to a higher risk of developing chronic obstructive pulmonary disease (COPD), according to new research looking at incidence of the disease in over 55,000 nurses in the USA.
