DNA DYSFUNCTION: Scientists have discovered a confirmed genetic link to erectile dysfunction. Researchers pinpointed a stretch of DNA where variations made it more difficult for men to perform as expected. The finger of suspicion points to a gene called SIM1 which could be a target for new impotence treatments. Lead researcher Dr Eric Jorgenson said: “Identifying this SIM1 locus as a risk factor for erectile dysfunction is a big deal because it provides the long sought-after proof that there is a genetic component to the disease.” Besides having a potential influence on men’s erections, SIM1 is thought to play a role in brain development. The research is reported in the journal Proceedings Of The National Academy Of Sciences. TACKLING DIABETES: More evidence has come to light about patients “reversing” their Type 2 diabetes by changing their diets. A new article details how three patients in Canada were able to stop their diabetes medication after following a “therapeutic fasting” diet. The new cases, detailed in the journal BMJ Case Reports, include three patients from Toronto who were referred to an intensive dietary management clinic. The patients were put on “therapeutic fasting” diets which “reversed” their insulin resistance, the Canadian authors wrote. The authors recommend that anyone with Type 2 diabetes who is considering making drastic changes to their diet speak to their healthcare professional first. MIND DRAIN: Mental health disorders are expected to drain €14 trillion per year from the global economy by 2030, experts have said. The Lancet Commission on Global Mental Health and Sustainable Development urged high-income countries to spend 10% of their health care budget on mental health. Currently, mental health receives less than 5%, even in these richer nations. Low and middle-income countries should raise their spending on mental health from less than 1% of the budget to at least 5%, said the Commission, which brought together 28 experts from around the world.
