Battling Alzheimer’s
The Story: The data from the latest experimental drug designed to treat Alzheimer’s disease, shows strong evidence of slowing cognitive decline. The latest drug, Donanemab, showed a 29% slower rate of decline in cognitive function.
What is Alzheimer’s Disease?
Alzheimer’s disease is a form of progressive dementia often beginning with memory loss, which worsens until an individual may be unable to speak or move. It is estimated that over 6 million Americans live with Alzheimer’s, for which there is no cure. In Alzheimer’s disease, many changes occur in the brain tissue. There is profound shrinkage of the brain and loss of function of brain cells. This is thought to be due to an increase in a toxic protein, called beta-amyloid, which clumps together and forms plaques. Donanemab specifically targets beta-amyloid proteins, to lower levels of these plaques in the brain.
Risk Factors for Alzheimer’s
Like many conditions, Alzheimer’s disease is related to many different factors, such as genetics and lifestyle. One genetic factor is the apolipoprotein E (APOE) gene, which can be inherited from the mother and father. Those possessing either the e3 or e4 subtypes of APOE are at an elevated risk for developing Alzheimer’s disease. This is such an influential factor, that if one inherits APOE e4 from both their mother and father, this may increase their risk by 8-12fold. Chris Hemsworth, an actor who is often a picture of health for many, received the shocking news that he carries a copy of the APOE e4 gene. He, and many others, can rest assured that genetics is just one part of the whole story. The presence of other vascular and metabolic diseases, such as heart disease, and diabetes, can put an individual at risk for developing Alzheimer’s disease, so managing one’s blood pressure, weight, blood sugar, and remaining physically active, are all viable ways to reduce the risk of developing Alzheimer’s disease. While folks continue to try and lower their risk, the development of drugs to treat Alzheimer’s is a blossoming field, with lots of success to come.
Bariatric Complications
A recent autopsy report has shed light on Lisa Marie Presley’s cause of death in early 2023, a complication due to a bariatric surgery she underwent years earlier. Presley, the daughter of famed rock and roll star Elvis Presley, passed due to a bowel obstruction, which transpired as a result of her previous bariatric surgery and resulted in a buildup of acids in her body.
Bariatric surgeries alter the digestive system to assist with weight loss. There are many types of bariatric surgery, but the majority work by minimizing the stomach size, so that less food is ingested. Aside from bowel obstructions, these surgeries carry many long-term risks, such as malnutrition, hernias, and internal bleeding. Nevertheless, these risks are relatively rare, and many celebrities, including famed singer Mariah Carey, have opted to undergo this surgery and emerged free from complications.
Long-term weight loss is incredibly difficult due to the body’s propensity to regain weight, and bariatric surgery provides a long-lasting solution to this problem. It is, however, a very invasive procedure, and so the race to develop a drug to assist in weight loss is on. Drugs such as Ozempic and Saxenda, work by reducing appetite and increasing feelings of fullness, and have shown results in helping patients lose weight. In June 2023, a new drug candidate, retatrutide, showed an astounding 25% reduction in body weight in obese individuals after 48 weeks. As the development of these medications continues, it is possible that bariatric surgeries become less common, in favor of more convenient medications.
Heat Wave Woes
Fans of country star Jason Aldean flocked to Connecticut for the start of his latest tour. Midway through his performance, Aldean ran off stage and did not return. It turns out, Aldean suffered from a bout of heat exhaustion, a condition that happens when the body overheats. Fortunately, Aldean recovered after rehydrating with intravenous (IV) fluids and went on to continue the tour.
The summer of 2023 has brought with it extreme weather conditions including unprecedented heat waves. Phoenix, AZ, recorded 19 consecutive days over 110 degrees Fahrenheit. This is a story shared by many Americans this summer, who are struggling to stay cool. While everyone enjoys sunshine and nice weather to an extent, it is important to be aware of the risks posed by extreme heat.
These risks include dehydration, heat exhaustion, heat stroke, and rhabdomyolysis, where the body’s muscle tissue dies and damages the kidneys. In order to prevent these potentially life-threatening conditions, steps must be taken. Drinking fluids to stay hydrated, can prevent dehydration as the body cools itself by producing sweat. As well, taking frequent breaks from doing physical activity outside, can help the body recover from the demands of exertion in high heat. It is important to know the signs and symptoms of heat-related illnesses. Heat exhaustion, like what Jason Aldean experienced, can come with heavy sweating, nausea, headaches, or even fainting. In those situations, it is important to rehydrate and visit a hospital if necessary.
And it wasn’t just Jason Aldean. Israeli Prime Minister Benjamin Netanyahu experienced a similar incident when he was rushed to the hospital after a day in the sun. Fortunately, he recovered from this episode of dehydration and dizziness, and encouraged his country to drink more water during their own heat wave, advice that is relevant around the world.
Not-So-Prime Energy Drinks
After taking the world by storm in 2022, Prime sports drinks have made headlines once more. The brand, launched by content creators Logan Paul and KSI, sells sports drinks aiming to hydrate consumers. As of late, versions of these drinks with high caffeine content, have been sold in Canada. These drinks have been recalled by Health Canada, as they exceed the limit of caffeine tolerated by the Canadian authorities. In New York, Sen. Charles Schumer called for a probe into the company’s marketing, since it is popular among children despite selling a product with caffeine levels notably higher than even a cup of coffee.
Caffeine is a stimulant compound that is widely consumed around the world for its wakefulness-promoting qualities. While commonly found in coffee, it is also present in smaller quantities in tea, and some sodas. Aside from its ability to promote mental alertness, caffeine has a number of other effects, including relieving headaches and enhancing athletic performance. Up to 400 mg per day is considered a safe dose in most healthy adults, which approximately equates to 4 cups of coffee.
Prime energy drinks contain 200mg of caffeine, which exceeds the Canadian limit of 180mg per drink. Large doses of caffeine can come with dangerous side effects, including insomnia, anxiety, nausea, and even seizures. Caffeine is not recommended for children in the USA, and even in Canada, guidelines recommend much lower amounts than are safe in adults. Energy drinks have been associated with increases in emergency department visits, as well as in binge-drinking episodes among college students.
Energy drinks can also have high levels of sugar, which is linked to weight gain, cardiovascular disease, and the development of type 2 diabetes. Energy drinks may also contribute to the development of aggressive behavior, and high blood pressure, which is particularly concerning considering that between 30-50% of adolescents have reported consuming energy drinks. Responsible consumption of caffeine and energy drinks is vital to minimize any risks, especially in children.
