Here are some of the latest health and medical news developments, compiled by the editors of HealthDay:
No More Confirmed Ebola Cases in Liberia
There are no more confirmed cases of Ebola in Liberia, but more than 100 people are still under surveillance, a health official said Friday.
The last four patients infected during the West African country's recent string of Ebola cases have recovered and will be discharged Monday, according to Deputy Health Minister Tolbert Nyenswah.
"There are no Ebola cases anywhere in Liberia as we speak," he told the Associated Press.
But Nyenswah added that it "is still too early to say it is over," noting that 123 people who were in contact with the infected patients are being monitored.
Liberia was declared Ebola transmission-free on May 9, but a 17-year-old boy died from the disease in late June. There were five more cases, including a woman who died earlier this week and the four patients who have recovered, the AP reported.
Retirement Good For You: Study
Retirement can be good for your health, according to a new study.
Researchers looked at thousands of American retirees and found that many showed notable improvements in health and happiness immediately after leaving the workforce, and that those positive effects endured over time, NBC News reported.
"Retirement has long lasting benefits to individual well-being," concluded the study by the National Bureau of Economic Research.
It should be noted that the people in the study were not disabled, unemployed or forced into early retirement by poor health, and had worked for at least 20 years and retired when they were eligible for a pension or Social Security, NBC News reported.
Pilots Should Undergo Psychological Tests: Task Force
Psychological tests should be given to all airline pilots, an expert panel says.
It also said that airlines should conduct random drug and alcohol tests on pilots and that there should be "robust" oversight of yearly pilot medical checks, NBC News reported.
The task force conducted a review that was ordered after a Germanwings pilot crashed an airliner into the French Alps in March, killing all 150 people on board. The results were released Friday.
The panel included experts from airlines, flight crews, doctors and aviation officials, and was led by Europe's aviation safety regulator, EASA. It called for an international medical database with details of medical check-ups done to assess whether pilots are fit to fly, NBC News reported.
Another recommendation was to have two pilots in the cockpit at all times.
