Watch out for tall, fast-moving cars. The height of a vehicle, not only its speed, determines its potential danger to a pedestrian, new research shows. “Multiple factors — in this case speed and vehicle height—converge to create negative outcomes on the road,” said David Harkey, president of the Insurance Institute for Highway Safety (IIHS). Measurements of the vehicles involved were used to examine the moderating effect of hood height.  “Our fondness for tall SUVs and pickups has intensified [the consequences of speeding],” Harkey noted in an IIHS news release. The report involved an analysis of 202 crashes involving people ages 16 and older in cities across the United States. The accidents occurred between 2015 and 2022. In general, higher vehicle front ends increased the likelihood of both moderate and serious pedestrian injuries, data showed. At 27 mph, the average speed of the crashes, a median-height car had a 60% chance of causing moderate injuries to a pedestrian and a 30% chance of causing serious injuries. Risks rose along with hood height, however: A median-height pickup — with a front end 13 inches higher than that of a median car — had an 83% chance of causing moderate injuries and a 62% chance of causing serious injuries. This tracks with earlier IIHS research that found that vehicles with taller front ends are more likely to kill…  read on >  read on >

Holiday travel is always stressful, but particularly so for people with food allergies. Airlines don’t always honor requests to protect the health of people with food allergies during flights, a new study published Dec. 5 in the Journal of Allergy and Clinical Immunology. found. Many people with food allergies say that airlines promise to take steps to protect their health, but then don’t follow through: 20% were promised food allergy-related cabin announcements that didn’t happen 17% were promised allergen-free buffer zones that weren’t established 23% were promised allergy-free food options that weren’t offered “We are not asking for the moon and stars, we just want reasonable accommodations that are promised in advance of travel to be honored at 30,000 feet,” said study co-author Lianne Mandelbaum, founder of the non-profit No Nut Traveler. “On every flight it is uncertain if and how crew members will accommodate nut allergies, and this adds tremendous unnecessary stress,” Mandelbaum said. “Flying with food allergies is akin to a game of roulette, each flight a random spin around the wheel.” For this study, researchers surveyed more than 4,700 individual patients and families around the world to assess their concerns related to air travel with food allergies. Travelers with food allergies said they were most often worried about whether airlines would follow through on accommodations arranged during the flight-booking process. They also…  read on >  read on >

WEDNESDAY, Nov. 27, 2024 — Thanksgiving travel is a must for millions of Americans, but those plans will be complicated for some because they’re traveling with a loved one who has Alzheimer’s disease or dementia. “A family trip to visit a loved one, friend, or favorite destination can be a great way to spend Thanksgiving, including for those affected by Alzheimer’s disease and other dementia-related illnesses,” Jennifer Reeder, director of educational and social services for the Alzheimer’s Foundation of America, said in a news release. “Whether traveling near or far, there are preparations and adaptations family caregivers can make to help their loved one feel more comfortable and relaxed throughout the trip,” she added. Some tips to help holiday travel stay focused on family and joy include: Before embarking, family and friends should make sure that their loved one can travel at all, Reeder said. As dementia progresses, travel may become too difficult. It’s worth consulting with their doctor to make sure travel is recommended, based on how long the trip will be and the stage of the person’s illness. If the person can travel, make plans that take their abilities into account. Plan travel to minimize their anxiety and stress — for example, they might travel better at specific times of the day, or travel better by plane or by car. During travel, companions…  read on >  read on >

Next time you’re on a cruise, be wary of your (or your neighbor’s) private balcony hot tub, researchers warn. These luxe cabin features were pinpointed as a source of outbreaks of the respiratory illness Legionnaires disease that broke out on two ships. The Legionella bacterium thrives in wet, warm conditions, so “hot tubs offer favorable conditions for Legionella growth and transmission when maintained and operated inadequately, regardless of location,” said a team of researchers from the U.S. Centers for Disease Control and Prevention. And while more public bathing spots onboard may be rigorously cleaned by staff, “private hot tubs on cruise ships are not subject to the same maintenance requirements as are public hot tubs in common areas,” said a team led by Sooji Lee, an epidemiologist at the CDC’s National Center for Immunization and Respiratory Diseases. Legionnaires disease is a rare form of pneumonia caused by Legionella bacteria. The germ is sometimes found in fountains, spray parks, hot tubs, showers and faucets. People can contract the disease by breathing in a mist or vapor containing the bacteria.  The first cruise ship outbreak covered by the new report occurred on an unnamed vessel during a two-week cruise in November 2022. By May of 2023, five passengers who took part in that cruise had gotten sick with Legionnaires, the researchers reported. Three more passengers on the same ship,…  read on >  read on >

Folks with peanut allergies don’t have to worry that someone might be munching on the nuts during an airline flight, researchers report. It turns out there’s no evidence to the commonly held belief that nut allergens can be spread through aircraft ventilation systems, a new review concluded. “In fact, food-induced allergic reactions are around 10–100 times less common during flights than ’on the ground’, perhaps because of the multiple precautions food-allergic passengers take when flying,” wrote the research team led by Paul Turner, a clinical professor of allergy and immunology with the Imperial College London’s National Heart & Lung Institute. For the review, published Oct. 15 in the Archives of Disease in Childhood, researchers compiled all published evidence on the subject dating back to 1980. Overall, any allergic reactions to food caused by airborne particles are rare, researchers found. Notable exceptions include vapors from fish or seafood and exposure to wheat flour at work. Peanut allergens can be detected at very low levels in the air while shelling nuts, researchers said, but the dust settles quickly and can only be detected close to the nuts. That means very little peanut dust circulates in the air. What’s more, air is completely exchanged every three to four minutes during a flight by the cabin’s ventilation system. Half of the cabin’s air intake is recirculated air that has…  read on >  read on >
