A new study published in The BMJ has found that antidepressant use may be associated with weight gain over time. “Patients who were normal weight were more likely to transition to overweight, and overweight patients were more likely to transition to obesity if they were treated with antidepressants,” said study co-author Rafael Gafoor, a primary care and public health researcher at King’s College London, in an email to TIME.

According to the head of medical charity Doctors Without Borders (MSF) mission in the city, two out of three Ebola patients who escaped quarantine in the Democratic Republic of the Congo's Mbandaka have died.

Meanwhile, the WHO said on Wednesday it was speeding up efforts with nine countries neighbouring the Democratic Republic of Congo(DRC) to attempt to prevent the spread of the current Ebola outbreak beyond its borders. The UN agency said teams are being deployed to assess how prepared the countries are.
