Higher blood pressure may be linked to brain disease and Alzheimer’s

first_imgShare LinkedIn Share on Twitter For the study, 1,288 older people were followed until they died, which was an average of eight years later. The average age at death was 89 years. Blood pressure was documented yearly for each participant and autopsies were conducted on their brains after death. The average systolic blood pressure for those enrolled in the study was 134 mmHg and the average diastolic blood pressure was 71 mmHg. Two-thirds of the participants had a history of high blood pressure, and 87 percent were taking high blood pressure medication. A total of 48 percent of the participants had one or more brain infarct lesions.Researchers found that the risk of brain lesions was higher in people with higher average systolic blood pressure across the years. For a person with one standard deviation above the average systolic blood pressure, for example 147 mmHg versus 134 mmHg, there was a 46 percent increased risk of having one or more brain lesions, specifically infarcts. For comparison, the effect of an increase by one standard deviation on the risk of having one or more brain infarcts was the equivalent of nine years of brain aging.Those with one standard deviation above the average systolic blood pressure also had a 46 percent greater chance of having large lesions and a 36 percent greater risk of very small lesions. Arvanitakis noted that an important additional result of the study was that people with a declining systolic blood pressure also had an increased risk of one or more brain lesions, so it was not just the level but also the declining blood pressure that was associated with brain lesions.Separately, higher average diastolic blood pressure was also related to brain infarct lesions. People who had an increase of one standard deviation from an average diastolic blood pressure, for example from 71 mmHg to 79 mmHg, had a 28 percent greater risk of one or more brain lesions.The results did not change when researchers controlled for other factors that could affect the risk of brain lesions, such as whether they used high blood pressure drugs.When looking for signs of Alzheimer’s disease in the brain at autopsy, researchers found a link between higher average late-life systolic blood pressure across the years before death and a higher number of tangles, but not plaques. Arvanitakis said this link is difficult to interpret and will need more research.“While our findings may eventually have important public health implications for blood pressure recommendations for older people, further studies will be needed to confirm and expand on our findings before any such recommendations can be made,” said Arvanitakis.Limitations of the study include that researchers did not have access to blood pressure of participants in middle age, only in later life, and that blood pressure information was recorded only once a year and not more frequently.

Researchers also found a link between higher blood pressure and more markers of Alzheimer’s disease, tangles in the brain.“Blood pressure changes with aging and disease, so we wanted to see what kind of impact it may have on the brain,” said study author Zoe Arvanitakis, MD, MS, of the Rush Alzheimer’s Disease Center at Rush University Medical Center in Chicago, and a Fellow of the American Academy of Neurology. “We researched whether blood pressure in later life was associated with signs of brain aging that include plaques and tangles linked to Alzheimer’s disease, and brain lesions called infarcts, areas of dead tissue caused by a blockage of the blood supply, which can increase with age, often go undetected and can lead to stroke.”Healthy blood pressure is less than 120/80 millimeters of mercury (mmHg). High blood pressure is above 140/90 mmHg. The higher number is called systolic blood pressure, the pressure in the blood vessels when the heart beats. The lower number is called diastolic blood pressure, the pressure when the heart is at rest.last_img read more

17 passengers turned back or quarantined in Jamaica over yellow fever worry

first_imgHealthNewsRegionalTravel 17 passengers turned back or quarantined in Jamaica over yellow fever worry by: Caribbean 360 – June 28, 2016 Share Share Share Tweetcenter_img Sharing is caring! The government has said it is trying to prevent the yellow fever virus from reaching Jamaica, where the disease does not occur but where the mosquito vector and human hosts are present.KINGSTON, Jamaica, Tuesday June 28, 2016 (Caribbean 360) – Nine passengers who flew into Jamaica yesterday were refused entry, while another eight were quarantined because of yellow fever concerns.The 17 were among travellers who flew into the island from Trinidad & Tobago and Panama and were unable to produce evidence that they were vaccinated against the virus, according to the Jamaica Gleaner newspaper.It quoted Minister of Health Dr. Christopher Tufton as confirming that five of the passengers arrived on Caribbean Airlines from the twin-island republic and they were all sent back home, while the other 12 came in from Panama. Of those 12, four were refused entry and the other eight quarantined.Tufton said Jamaica has to take the threat of yellow fever seriously. Yellow fever is an acute viral disease transmitted by infected mosquitoes. Symptoms include fever, headache, jaundice, muscle pain, nausea, vomiting and fatigue, and according to the World Health Organization (WHO), a small proportion of patients who contract the virus develop severe symptoms and approximately half of those die within seven to 10 days.Earlier this month, the Jamaica government issued a statement indicating that all travellers over the age of one year who arrive in Jamaica from countries where there is risk of yellow fever transmission – including those passengers transiting those countries – would be required to produce a valid certificate to show they have been vaccinated.It said it was taking the step to prevent the importation of the virus into Jamaica where the disease does not occur but where the mosquito vector and human hosts are present.“Failure to produce a valid yellow fever vaccination certificate at a Jamaican point of entry may lead to refusal of entry, or quarantine until the traveller’s certificate is produced,” the government advised.The countries for which the certificate is required for entry into Jamaica are based on a WHO advisory. Those countries are: Angola, Argentina, Benin, Bolivia, Brazil, Burkina Faso, Burundi, Cameroon, Central African Republic, Chad, Colombia, Congo, Côte d’Ivoire, Democratic Republic of the Congo, Ecuador, Equatorial Guinea, Ethiopia, French Guinea, Gabon, Gambia, Ghana, Guinea, Guinea-Bissau, Guyana, Kenya, Liberia, Mali, Mauritania, Niger, Nigeria, Panama, Paraguay, Peru, Senegal, Sierra Leone, South Sudan, Suriname, Togo, Trinidad and Tobago, Uganda and Venezuela. 73 Views   no discussionslast_img read more

Confident Woods plays practice round ahead of comeback

first_imgTiger Woods declared it was all systems go after sneaking in nine quick holes at Torrey Pines on Tuesday, two days ahead of his official PGA Tour comeback at the Farmers Insurance Open.On a sparkling winter morning in southern California, with not a cloud in the sky and barely a ripple on the Pacific Ocean, Woods showed he is still an early bird when he teed off shortly after the sun had risen over the Laguna Mountains.He played the back nine on the South Course and was finished by 9.30 A.M.Woods did not speak to reporters after his round, but had a quick word with ESPN while he was playing. He was confident that his game – and body – was heading in the right direction.“You have to beat balls for a little bit of time to build up your endurance and muscles. I feel like I’ve done that and now it’s time to play a tournament,” he said.Woods, who has barely played in three years due to a serious back injury, returned after a 10-month absence when he took part in the unofficial Hero World Challenge, finishing a respectable ninth out of 18 players and swinging with apparent freedom.“I’ve had a little more time to get ready for this event,” he said. “I’ve played a lot more golf and overall I feel like I’ve made some nice changes. I feel good.”Woods, 42, will play the first two rounds with fellow Americans Patrick Reed and Charley Hoffman.He hardly needs a practice round at Torrey Pines to know his way around. He has won on eight occasions here, seven times at the PGA Tour event and most notably at the 2008 U.S. Open.That 14th major title was perhaps his greatest achievement, coming as it did as he carried multiple leg injuries.Few thought at the time that nearly 10 years later he would not have added to his major haul.The US Open was played on Torrey Pines’ South Course, while the Farmers uses the South for three rounds while one round is contested on the easier North Course.Two years ago Woods gingerly limped off the course after playing just 11 holes of the first round, a week after shooting a career-worst 82 at the Phoenix Open.He returned last year but missed the cut, before playing one round at the European Tour’s Dubai Desert Classic and withdrawing due to back spasms.Soon afterwards, with multiple microdiscectomy surgeries seemingly having failed, Woods decided to have a spinal fusion operation last April in an attempt to reduce his searing back pain and allow him to play golf again.He will get a look at the North Course on Wednesday in the pro-am.Woods has won 79 times on the PGA Tour, second only to Sam Snead’s 82.last_img read more
