An experimental treatment happens to be the solution to delay Alzheimer's symptoms in some people. These people are the ones who are genetically destined to get the disease in their 40s or 50s. These new findings form ongoing research has now been caught up in Trump administration funding delas. The early results of the study has been published on Wednesday and the participants too are worried that politics could cut their access to a possible lifeline.
One of the participants had said, "It is still a study but it has given me an extension to my life that I never banked on having." The participant is named Jake Henrichs, form New York City, who is 50 years old. He is one of them to be treated in that study for more than a decade now and has remained symptom-free despite inheriting an Alzheimer's-causing gene that had killed his father and brother around the same age.
Two drugs which can modestly slow down early-stage Alzheimer's are sold in the United States. These drugs clear the brain of one of its hallmarks, a sticky gunk-like part called the amyloid. However, there have not been any hints that removing amyloid far earlier, way many years before the first symptoms appear, may postpone the disease.
The research is led by Washington University in St Louis, which involved families that passed down rare gene mutation as participants. This meant it was almost guaranteed that they will develop symptoms at the same age their affected relatives did.
The new findings is based on a subset of 22 participants who received amyloid-removing drugs the longest, on average eight years. Long-term amyloid removal cut in half their risk of symptom onset. The study is published in the journal Lancet Neurology.
Washington University's Dr Randall Bateman, who directs the Dominantly Inherited Alzheimer's Network of studies involving families with these rare genes says, "What we want to determine over the next five years is how strong is the protection. Will they ever get the symptoms of Alzheimer’s disease if we keep treating them?”
The researchers before though did not know what exactly caused Alzheimer's which affects nearly 7 million Americans, most of them in their later life. However, it is clear that these silent changes occur in the brain at least two decades before the first symptom shows up. The big contributor. At some point amyloid buildup can trigger a protein named tau that then starts to kill neurons, which can lead to cognitive decline.
Researchers are now thus studying the Tau-fighting drugs and are looking into other factors, like inflammation, brain's immune cells and certain virus.
The National Institute of Health (NIH) has expanded its focus as researchers have found more reasons for Alzheimer's. In 2013, the NIH's National Institute on Aging funded 14 trials of possible Alzheimer's drugs over a third targeting amyloid. By last fall, there were 68 drugs and 18% of them target amyloid. However, there are scientists too who think that amyloid is not everything and their is way more in the brain tissue, immune cells, and more which can be studied.

Three suspected hantavirus patients have been evacuated from the ship and are on their way to receive medical care in the Netherlands, said Dr Tedros Adhanom Ghebreyesus, WHO Director-General, today.
The three patients evacuated from the MV Hondius cruise ship include
The WHO chief noted that the global health agency “continues to work with the ship’s operators to closely monitor the health of passengers and crew, working with countries to support appropriate medical follow-up and evacuation where needed”.
“Monitoring and follow-up for passengers on board and for those who have already disembarked has been initiated in collaboration with the ship’s operators and national health authorities,” Dr Ghebreyesus said.

Some passengers aboard the Hondius began experiencing serious health complications after the ship, carrying about 150 passengers, departed Argentina on April 1.
Initially, it was considered a severe acute respiratory infection; later, three people died.

According to the WHO, hantaviruses are zoonotic viruses that naturally infect rodents and are occasionally transmitted to humans.
Symptoms include:
A team of scientists at South Africa’s National Institute for Communicable Diseases identified the strain of hantavirus linked to the cases.
In a presentation to parliament, the South African health minister said the Andes strain of hantavirus, which can spread human-to-human, had been identified in two people who disembarked from the cruise ship.
The Andes virus is the only hantavirus strain with documented human-to-human transmission and is more commonly found in South America.

Some people love tea, some can't get enough of coffee, but rarely does one think about if the same could influence disease risk later in life. According to a new study, women's risk of osteoporosis could be influenced by their choice of tea or coffee. Osteoporosis is a common occurrence in women aged 50 years and above. Statistics suggest that one in three women will likely be diagnosed with the disease, which renders the body incapable of replacing old bone after it undergoes wear and tear. This means bones become weak, brittle, and more prone to fractures. Bone problems at an advanced age in women can also slow down healing.
Older women are at a higher risk of osteoporosis, and that is because of oestrogen. Oestrogen supports bone metabolism, and its levels drop after menopause. Surgery can help remove a woman's ovaries, thereby resulting in the same effect. Researchers at Flinders University in Australia evaluated tea- and coffee-drinking habits of approximately 9,700 US women aged 65 years and above. Participants were required to self-report their tendencies in the survey on four occasions over a 10-year period.
The study also gathered data on women's bone health, measuring bone mineral density in the hip and the narrow connection to the hip with X-ray beams to deduce mineral levels in the bone. Researchers found that women who regularly drank tea had significantly higher hip BMD than those who did not. This could be because of tea compounds known as catechins that could provide the boost cells need to build strong bones. Even smaller differences can significantly improve bone health.
Researchers noted that tea intake could be particularly beneficial for women dealing with obesity. Coffee habits, alternatively, had a different impact on BMD. Studies suggest that women who drank more than five cups of coffee a day were more likely to have lower BMD levels, thereby suggesting that caffeine can negatively affect calcium absorption in the body. Furthermore, experts noted that drinking any amount of coffee can reduce BMD levels in women, especially those who consumed high levels of alcohol.
Scientists note that, because of the limited scope of the study, more research is required in this area to ascertain the results. However, the study offers insights into the possible benefits of drinking tea for women living with osteoporosis. It can go a long way in improving overall wellness and long-term bone health in women.

A team of scientists at South Africa’s National Institute for Communicable Diseases has identified the strain of the Hantavirus that has caused three deaths and infected seven so far aboard the MV Hondius ship in the Atlantic Ocean.
In a presentation to the parliament today, the South African Health Minister revealed that the Andes strain of hantavirus, which spreads human-to-human, has been identified in two people who came off the cruise ship.
“Incredible work of @nicd_sa, South Africa, in sequencing the #hantavirus. There has been excellent collaboration as @WHO
works to coordinate efforts and actions of governments, experts around the world, the Ship to keep people safe,” said Dr. Maria Van Kerkhove, director of epidemic and pandemic preparedness and prevention at the World Health Organization (WHO), in a post on social media platform X.
The NICD scientists found that the Andes strain was the cause of infection in a Dutch woman who died in Johannesburg, and a British man who is still in hospital. Both had become ill on the ship, Reuters reported.
“This is the only strain that is known to cause human-to-human transmission, but such transmission is very rare and, as said earlier, only happens due to very close contact,” the Minister said.
Other strains of hantavirus are more commonly transmitted to humans through contact with infected rodents or their urine, droppings, or saliva.

As per the WHO, hantaviruses are zoonotic viruses that naturally infect rodents and are occasionally transmitted to humans.
Globally, an estimated 100,000 to 200,000 hantavirus infections occur each year. The majority of these cases are in Asia, particularly China. Most are sporadic or occur in small clusters, linked to contact with infected rodents.
“Hantaviruses are a group of viruses carried by rodents that can cause severe disease in humans. Infection with hantaviruses is found in many parts of the world. Thousands of infections are estimated to occur each year," Van Kerkhove said.
The Ande virus is the only strain of virus with documented human-to-human transmission. It is more common in South America.

"Although uncommon, limited human‑to‑human transmission of HPS due to the Andes virus has been reported in community settings involving close and prolonged contact. Secondary infections among healthcare workers have been previously documented in healthcare facilities, though they remain rare,” WHO said in its situation report.
The WHO also currently assesses the risk to the global population from this event as low and will continue to monitor the epidemiological situation and update the risk assessment as more information becomes available.
"People really do need to understand that there are different degrees of person-to-person transmission," said Angela Rasmussen, a virologist with the University of Saskatchewan's Vaccine and Infectious Disease Organization, as quoted by CBS News.

In the case of hantavirus, individual people are usually the end of the line, Rasmussen said, noting that this makes this cluster of cases unusual.
"So this virus — right now anyways — doesn't seem to be as big a risk as something like flu," the expert said.
While symptoms might not appear for weeks, the strain can escalate quickly, leading to severe respiratory failure with a death rate of roughly 40 per cent.
