New Swedish research suggests that up to 5% of 70-year-olds have glaucoma, and half of those diagnosed didn’t even know they had the disease. “Of those who were diagnosed with glaucoma via the study, 15 people — or 2.7% of all participants — were unaware that they had the disease before being examined,” said study author Lena Havstam Johansson, a PhD student at the University of Gothenburg and a specialist nurse at Sahlgrenska University Hospital, both in Gothenburg, Sweden. “So half of those who turned out to have glaucoma were diagnosed because they took part in the study.” Those who received this diagnosis were able to start treatment with daily eye drops that lower the pressure in the eye and slow optic nerve damage. Researchers noted that those with glaucoma had similar levels of physical activity and did not smoke more or drink more alcohol than those without the disease. Their overall quality of life was as good as the others. They were not more tired or more depressed. “This was a positive surprise, and was a finding that I hope can bring comfort to many people who have been diagnosed with glaucoma. It’s hard to live with a disease that gradually impairs vision, but life can still be good in many ways,” Havstam Johansson said in a University of Gothenburg news release. Yet, those…  read on >  read on >

Some people mistrust the safety and effectiveness of human vaccines for COVID-19 and other diseases, a fact that became abundantly clear during the pandemic. Now, a new survey of 2,200 dog owners shows this mistrust may often extend to canine vaccinations. The finding suggests there is spillover between the issues, with those who have negative feelings about human vaccines more likely to hold these same views about vaccinating their pets, even when it comes to deadly conditions like rabies. “We knew that this phenomenon existed, but we didn’t know how prevalent it was. We didn’t know where it came from and what policy and public health implications might be, and that’s why we set out to do this research,” said Matt Motta, an assistant professor of health law, policy & management at Boston University School of Public Health, who conducted the research with his sister, Dr. Gabriella Motta, a veterinarian at Glenolden Veterinary Hospital in Pennsylvania. “A lot of our motivation for this project was born out of conversation that she and I had, her lived experience as a vet, encountering folks who didn’t want to vaccinate their pets and trying to understand why,” he explained. What they found is that nearly 40% of dog owners think dog vaccines aren’t safe. About 20% think they’re not effective. And 30% think they aren’t medically necessary. About…  read on >  read on >

The blockbuster drug Ozempic has become a household name for its ability to spur weight loss. Now an early study hints at an intriguing possibility: The drug might allow people newly diagnosed with type 1 diabetes to drop their daily insulin shots. Experts emphasized that the findings are based on only 10 patients, and larger, longer-term studies are necessary. However, all 10 patients were able to stop their meal-time insulin injections after starting semaglutide, the active ingredient in Ozempic. And most were also able to drop their long-acting insulin, which is used to keep overnight blood sugar levels in check. “It sounds like science fiction, that people with type 1 diabetes can stop taking insulin,” said lead researcher Dr. Paresh Dandona of the State University of New York at Buffalo. “This really opens up a new area of research,” he said. “Could we use this drug to change the natural course of type 1 diabetes?” Type 1 diabetes arises when the immune system mistakenly goes after cells in the pancreas that produce the hormone insulin. Insulin has the critical job of moving sugars from food into the body’s cells to be used as fuel. In order to survive, people with type 1 diabetes have to take synthetic insulin, via daily injections or a pump attached to the body. The disease is far less common than…  read on >  read on >

Your thinking and memory skills may take a hit decades after recovering from a concussion, a new study indicates. Scientists who studied male twins, from an average age of 67, found that earlier concussions were tied to lower scores on tests of thinking and memory. These men also had a more rapid decline in their cognitive skills — skills needed for reasoning and the acquisition of knowledge. “It is concerning and, honestly, since previous studies had not been able to capture the cognitive decline, it was not something I really was expecting to see,” said study author Marianne Chanti-Ketterl, a gerontologist at Duke University Medical Center in Durham, N.C. “But it is also promising because it’s something that we can intervene on.” Studying identical twins makes sense because they share the same genes and many of the same early life exposures. In this research, one person from each pair had sustained a traumatic brain injury (TBI) during their lifetime and the other hadn’t been injured. This study worked with data from nearly 7,200 white, male World War II veterans who were twins. The men took a thinking skills test when the study began, at age 67 on average. They took the tests three more times over 12 years. Those with a history of concussion had the brain injury 34 years earlier on average. Participants started…  read on >  read on >

The two “freezing” episodes that Sen. Mitch McConnell experienced recently weren’t strokes or seizures, the Capitol physician said in a new letter released Tuesday. “My examination of you following your August 30, 2023, brief episode included several medical evaluations: brain MRI imaging, EEG study and consultations with several neurologists for a comprehensive neurology assessment. There is no evidence that you have a seizure disorder or that you experienced a stroke, TIA [transient ischemic attack] or movement disorder such as Parkinson’s disease. There are no changes recommended in treatment protocols as you continue recovery from your March 2023 fall,” wrote Dr. Brian Monahan. Monahan had already cleared McConnell for work after the Senate Republican Leader froze for the second time in a month during a briefing last Wednesday in Kentucky. Monahan said in that earlier statement that he had talked with McConnell and his neurology team, and that McConnell can continue his work schedule. McConnell, 81, was injured in March when he fell at a dinner event at a Washington, D.C. hotel. The senator had a concussion and a broken rib. On two separate occasions since then, McConnell has frozen while speaking publicly, including for about 30 seconds on Wednesday, the Associated Press reported. He was “momentarily lightheaded,” McConnell’s office told the AP. “Occasional lightheadedness is not uncommon in concussion recovery and can also be expected…  read on >  read on >

You might think you know what a normal body temperature is, but there is no such thing. Analyzing the age-old belief that 98.6 Fahrenheit is normal human temperature, scientists at Stanford Medicine found that your temperature is personal. It also depends on age, sex, height and weight, and changes throughout the day. “Most people, including many doctors, still think that everyone’s normal temperature is 98.6 F. In fact, what’s normal depends on the person and the situation, and it’s rarely as high as 98.6 F,” said senior study author, Dr. Julie Parsonnet, a professor of medicine. The normal temperature of a tall, underweight 80-year-old man in the morning could be a degree lower than the afternoon temperature of a 20-year-old woman who is obese, she explained in a Stanford news release. Past research at Stanford found that Americans’ average body temperature has dropped from 98.6 F by about 0.05 F every decade since the 19th century. This is likely due to better health and living conditions that reduce inflammation. Today, a so-called normal body temperature is nearer to 97.9 F, the researchers noted. The idea of 98.6 F comes from a German study published in the 1860s. But even then, researchers noted that men and the elderly had lower temperatures than women and young adults. Temperatures in that study were also higher in the afternoon.…  read on >  read on >

A stressful or traumatic childhood experience — anything from parents divorcing to a sibling’s drug problem — may have long-term effects on a woman’s sexual health. These adverse childhood experiences may be linked to sexual inactivity and dysfunction in women later in life, a recent study reports. Health care providers should screen their patients with sexual dysfunction for adverse childhood experiences, researchers recommend. Doctors should offer these women treatment that could include a referral for counseling. “This research adds to the literature exploring sexual function in women,” said senior author Dr. Ekta Kapoor, assistant director of the Mayo Clinic Center for Women’s Health in Rochester, Minn. “Sexual dysfunction has a significant impact on a woman’s quality of life. Based on these findings, we encourage health care providers to screen for adverse childhood experiences in women with sexual dysfunction and offer multidisciplinary treatment including referral for counseling as needed. If the consequences of childhood adversity are not adequately addressed, other interventions to improve sexual function may not be successful,” Kapoor said. The study included more than 1,500 women, aged 40 to 65, who visited the Menopause and Women’s Sexual Health Clinic at the Mayo Clinic in Minnesota between 2015 and 2016. The women had concerns related to menopause and sexual health. Before their visit, they were asked to complete a survey that included questions about any…  read on >  read on >

Lots of children and adolescents have the condition known as ADHD, or attention-deficit/hyperactivity disorder. What should parents know? A number of treatments exist to help with functioning, including medications approved by the U.S. Food and Drug Administration. Typically, ADHD begins between ages 3 and 6, according to the U.S. National Institute of Mental Health. It can continue into adulthood. People can experience one of three types of ADHD. They are predominantly inattentive, with trouble focusing, following instructions and finishing tasks; predominantly hyperactive/impulsive, with behavior of being “constantly on the go,” talking excessively and interrupting others; and a combination of those symptoms. An increasing number of children are being diagnosed with ADHD. About 10% of children aged 3 to 17, about 6 million kids, have been diagnosed with ADHD as of 2019, according to the U.S. Centers for Disease Control and Prevention. Boys, at 13%, are more likely than girls, at 6%, to be diagnosed with ADHD. “Boys are also more likely to have the hyperactive-impulsive type. This type of ADHD is easier to spot than the quieter child who is inattentive,” said child psychiatrist Dr. Tiffany Farchione, who reviews ADHD drugs at the FDA. Untreated ADHD can have serious consequences, the FDA warns, including falling behind in school, having difficulties with friendships and experiencing conflicts with parents. Children with untreated ADHD also have more emergency…  read on >  read on >

FRIDAY, Sept. 1, 2023 (HealthDay News) – After Sen. Republican Leader Mitch McConnell froze for the second time during a Wednesday briefing in Kentucky, Congress’ attending physician has cleared him to continue working. Dr. Brian Monahan said in a statement that he had talked with McConnell and his neurology team, and that McConnell can continue his work schedule. McConnell, 81, was injured in March when he fell at a dinner event at a Washington hotel. The senator had a concussion and a broken rib. On two separate occasions since then, McConnell has frozen while speaking publicly, including for about 30 seconds on Wednesday, the Associated Press reported. He was “momentarily lightheaded,” McConnell’s office told the AP. “Occasional lightheadedness is not uncommon in concussion recovery and can also be expected as a result of dehydration,” Monahan noted. McConnell has revealed little about his health, but was known to have called his deputies in leadership after the Wednesday incident, the AP reported. His health has visibly declined in recent months. Some Republican senators have concerns about McConnell’s health and whether he will run for reelection in 2026, the AP reported. Most Republican senators have been publicly supportive of McConnell. The U.S. Senate is not in session at the moment, but it will reconvene soon.
