Neurosurgons propose a new framework for assessing traumatic brain injuries
Each year in the United States, nearly 5 million adults and children seek medical care for a traumatic brain injury.
Now after more than half a century, based on a mountain of data, and a team of international experts, a new proposal published in Lancet Neurology sets forth a new framework to overhaul how to more precisely assess the injuries, and to do a better job in caring for the patients.
Corresponding author for the new criteria is Dr. Geoff Manley. Manley is chief of neurosurgery at Zuckerberg General Hospital and a professor of neurosurgery at UC San Francisco. He is also a member of the UCSF Weill Institute for Neurosciences.
Manley said the current clinical guidelines are not very precise.
For years, trauma centers have used what's called the Glasgow Coma Scale to assess patients. Typically, and generally speaking, the measurement devices patients into three categories of TBIs: mild, moderate, or severe, and the patients are then treated accordingly, and that's a problem according to Manley. He explained how some patients categorized as having 'severe" TBI are often approached with a bias in prognosis, and the families are guided to consider withdrawing life support. Some of these patients have recovered and gone on to live full lives. He added on the other side of the spectrum, some patients diagnosed with "mild" TBIs, or a concussion are often just disregarded and sent home to recover.
"And we know from studies that we've done over the last 10 to 15 years, that a number of people with so-called mild TBA actually they're not mild at all," said the neurologist.
A case in point: Sean Sanford of San Francisco. Sanford writes fiction and music reviews, is a substitute teacher, and is currently getting his master's in creative writing.
He also really loves skateboarding. 8 years ago, he was about to show his good friends a new trick, but he slipped, fell, and hit his head on a concrete ledge.
Sean was knocked unconscious. When he came to, he saw his friends and his wife Candice standing over him asking him if he recognized any of them.
"I kept repeating myself and being like what are we don't like where are we? What's going on?" Sanford recounted.
His friends brought him to Zuckerberg Emergency. Clinicians used the Glasgow Coma Scale and assessed Sean with a bad concussion. Sean told CBS News Bay Area that he would be released, and that the concussion should be able to resolve with rest and time.
But Sanford told us the ER team decided, that before they are releasing him, that they would scan his brain. The next thing he knew, he was wheeled into surgery.
"They sent me into a surgery room, they called Dr. Manley who wasn't working that day. They called him in and they said we've got a patient who's cracked his skull and its bad and if he doesn't get treatment right now, he's going to die," remembered Sanford
Dr. Manley told CBS News Bay Area how SF General follows advanced protocols, but that he would like to provide the benefits and treatments to other trauma centers, especially those located in rural areas, and the patients they serve better tools and more precise chance of a proper assessment. Some patients with mild or moderate TBIs often develop symptoms long after they are dismissed from the hospital, and without follow-up or care, they go on to live debilitating lives.
An international coalition of experts and patients came up with the criteria. Manley is one of the corresponding authors. The new framework will soon be phased in at trauma centers across the U.S. on a volunteer basis.
The new criteria involve what Manley and the report called the "4 pillars": a clinical exam, biomarker blood tests which can show levels of tissue damage, imaging needed by patients who show certain levels of tissue damage, and then "modifiers" that include a patient's age, gender, mental health, support system, and even prior head injuries.
"We know that it's not just what the injury brings to the patient but what the patient brings to the injury," explained Manley on the inclusion of "modifiers".
As for Sanford, he needed follow-up care. After the accident, he developed epilepsy and depression. He is getting better, but it's a very slow process. Sanford now meditates and at the family store on Divisadero, helps his wife develop handmade products that promote relaxation.
"It's really a place of magic and a place of healing," noted the writer.
He still skateboards, but now, always with a helmet.

Bed Bugs May Have Been The First Urban Pest to Ever Plague Humans
Humans were letting the bed bugs bite long before beds existed, and while they do live on other species, we're the main reason this notorious parasite is still going strong. In fact, bed bugs might have been the first pest to plague our cities – earlier than the black rat, for instance, which joined us in urban life about 15,000 years ago, and even the German cockroach, which only got the memo about 2,100 years ago. Researchers think the blood-sucking pests – Cimex lectularius – first jumped from their bat hosts onto a passing human some 50,000 years ago, a move which would change the course of the insect species forever. Human bed bugs, it turns out, have boomed since the Last Glacial Maximum about 20,000 years ago. But it's a different story for those populations that continued living on bats. "Initially with both populations, we saw a general decline that is consistent with the Last Glacial Maximum; the bat-associated lineage never bounced back, and it is still decreasing in size," says entomologist Lindsay Miles, from Virginia Tech. "The really exciting part is that the human-associated lineage did recover and their effective population increased." The researchers were able to track this evolution because the human bed bugs have a much narrower genetic diversity, since only a few 'founders' probably came with us when we abandoned life in caves. But our move into cities around 12,000 years ago is what really kicked off the human bed bug boom. This was only briefly interrupted when DDT was invented in the 1940s. Populations crashed, humans slept sweetly, and then five years later, the bed bugs were back. Since then, bed bugs have travelled around the world with us, and even become resistant to our pesticides. For now, it seems, bed bugs are here to stay. It's been a long-term relationship, after all. The research is published in Biology Letters.

The #1 Anti-Inflammatory Diet Habit You Should Start, According to Dietitians
Eating more colors is a simple and effective way to eat a more anti-inflammatory diet. Each color adds a unique mix of phytonutrients, vitamins, minerals and fiber to your diet. Adding color is as simple as throwing spinach into a smoothie or having berries for you're trying to eat a more anti-inflammatory diet to reduce the risk of chronic disease or help manage symptoms of an inflammatory condition, the best place to start may be adding more color to your plate. 'An anti-inflammatory diet focuses on colorful, nutrient-dense foods like fruits and vegetables, healthy fats, and inflammation-fighting herbs and spices,' says Julie Pace, RDN. 'This pattern of eating can benefit most anyone, but is especially helpful for those managing health conditions such as autoimmune disorders, heart disease, menopause and digestive issues.', While there are plenty of anti-inflammatory foods that may not be vibrantly colored, such as nuts, seeds and grains, incorporating a wider range of colors in your diet is an easy and effective way to get started. Eating the rainbow not only makes your food look more appealing, but it effortlessly adds a wide variety of nutrients, antioxidants, and powerful plant compounds to your diet, helping to fight inflammation, support a healthy gut, and keep your immune system strong. 'Fruits and vegetables are different colors not just to look nice on our plates, but because each color has different health benefits,' says Marita Radloff, M.S., RDN. Phytonutrients are bioactive compounds found in plants that are responsible for vibrant hues, flavors, and smells, with each color representing a different nutrient with unique benefits. Anthocyanins are a family of flavonoids responsible for red, pink, blue and purple hues in fruits and vegetables, and they have powerful anti-inflammatory properties. 'For example, the deep blue-purple hue of blueberries comes from anthocyanins, natural antioxidants that reduce inflammation and protect your cells from damage,' says Melissa Jaeger, RD, LD. Carotenoids are another group of colorful phytonutrients, found in yellow and orange fruits and vegetables as well as leafy greens. As a precursor to vitamin A, carotenoids help protect cells and reduce inflammation caused by oxidative damage while also decreasing the production of inflammatory cytokines. Data suggests that 85 percent of the United States population is not getting the recommended amount of fruit each day, while 90 percent is falling short on vegetables. Focusing on more color in your diet will naturally help you eat more fruits and veggies, both of which play a significant role in overall health and reducing the risk of inflammatory diseases. While most research on fruit and vegetable intake and disease prevention is observational, studies repeatedly show a connection between higher intakes and a lower risk of inflammatory chronic diseases, such as metabolic syndrome, type 2 diabetes, osteoporosis, neurodegeneration, and cancer., 'Fruits and vegetables are rich in fiber, which plays a crucial role in maintaining a healthy gut microbiome. A balanced microbiome supports the body's immune system and has been linked to a reduced risk of chronic inflammatory diseases,' says Jaegar. As fiber is fermented by the bacteria in your gut, inflammation-fighting short-chain fatty acids are produced. Butyrate, a particularly beneficial short-chain fatty acid, provides energy to the cells in the gut lining, helping to strengthen its integrity and keeping inflammatory substances from leaking out of the gut into the rest of the body. Numerous vitamins and minerals, including vitamins A, D, C, E, B6, zinc, iron, copper, selenium, and magnesium, play key roles in combating inflammation. While you could take a supplement to boost your micronutrient intake, it probably won't have the same powerful anti-inflammatory effect as getting them from your diet. Research suggests that various compounds found in plants activate and intensify the inflammation-fighting power of various vitamins and minerals. For example, resveratrol, a polyphenol found in cranberries, blueberries, and plums, has anti-inflammatory and antipoxidant effects, and also acts synergistically with vitamins A and C. Aside from adding the rainbow to your plate, here are some other simple and effective ways to get more anti-inflammatory foods into your diet: Use more: 'Try adding a dash of turmeric to salad dressings, sprinkle cardamom over berries, or mix in parsley and oregano into your favorite dishes. These small additions to your meals can make a significant difference when it comes to fighting inflammation,' says Pace. Stock your freezer: Fresh isn't always best, especially when it comes to keeping nutrients intact. 'Frozen foods are often picked at the peak of ripeness and can be very convenient since they're already cut and you can pop them into the microwave to round out the colors on your plate,' says Radloff. Increase your colors one by one: If you're barely getting one serving of fruits or vegetables per day, don't overcomplicate it by adding too many at once. 'Set a goal to include at least one additional serving of fruits or vegetables in your diet each day,' says Jaeger. Get inspired by the Mediterranean diet: If you'd rather have a guideline to follow than just picking up more fruits and vegetables from the grocery store, following a simple Mediterranean meal plan can help. Eating more colors is a simple and effective way to eat a more anti-inflammatory diet, without overhauling your entire routine. Each color adds a unique mix of phytonutrients, vitamins, minerals and fiber to your diet to support your body's natural inflammation-fighting abilities. Additions as simple as blueberries and green spinach in your smoothie, red peppers with your snack, sweet potatoes for dinner, and blackberries in dessert can help you enjoy the benefits and incredible flavors of a more colorful diet.

Exactly How Many Times a Week To Walk To Improve Your Heart Health, According to Cardiologists
Exactly How Many Times a Week To Walk To Improve Your Heart Health, According to Cardiologists originally appeared on Parade. One of the best ways to support your heart is free, easy and can be done anywhere: walking. There's no shortage of scientific studies showing the many ways that walking benefits health. Some of the highlights: Walking regularly has been found to lower blood pressure, assist with weight loss, support cognitive health and lower depression. Pretty impressive for something that only requires a pair of sneakers!Perhaps you already know that walking supports health, but you're wondering how often you should do it to truly reap the benefits. Here's what cardiologists say it's important to keep in mind in terms of how often to walk a week, how long your walks should be and how fast you should When it comes to walking for heart health, Virginia Heart cardiologist Dr. Jonathan Segal, MD, says that any amount of walking is better than none at all. 'At the very simplest, do what you can,' he shares, adding that the more you do, the better. In terms of how many times a week you should walk if you want to improve your heart health, UT Southwestern Medical Center cardiologistDr. Ijeoma Eleazu,MD, says the gold standard of advice to follow comes from the American Heart Association, which recommends aiming for at least 150 minutes per week of moderate-intensity aerobic activity, such as brisk walking, or 75 minutes of vigorous-intensity activity. 'This breaks down to about 30 minutes a day, five days a week—enough to significantly reduce the risk of heart disease and stroke,' she explains. Related: With this in mind, people who want to improve their heart health should walk as much as possible, but at the very least walk for 30 minutes, five days a week. But even with this guideline in mind, it's important to do what you can. '[The general] recommendation should be adjusted depending on your overall health, previous fitness or activity level or any orthopedic or balance problems that may make you prone to falling, any lung disease or any other health issues,' says Dr. Louise Spadaro, MD, a cardiologist at St. Francis Hospital, The Heart Center, adding that it's best to talk with your healthcare provider before starting a new exercise program. Related: While 30-minute walks are especially beneficial, Dr. Eleazu says that shorter walks support heart health too. 'The key is consistency and hitting the recommended total duration each week. Longer walks—up to or even longer than 30 minutes—are great and can make time for reflection that can clear the mind, but shorter walks (even as short as 5 to 10 minutes multiple times a day) help break up activity into shorter, manageable sessions,' she explains. In terms of how quickly you should walk, Dr. Eleazu says should notice an increase in your heart rate, explaning, 'Walking at a moderate pace—where you breathe heavier but can still hold a conversation—is linked to better cardiovascular outcomes. A brisker pace increases heart rate and circulation more effectively than a casual stroll." Related: If you want to take your walks to the next level and do even more to support your heart, all three cardiologists say there are a few ways to do it. Dr. Eleazu recommends doing speed walking intervals, alternating between bursts of quick walking followed by slower walking. This is a way to get your heart up, allow yourself time to recover and get your heart rate up once again. Dr. Spadaro says you can also increase the distance of your walk. For example, if you currently walk one mile a day, you can gradually increase the distance to 1.5 miles. She adds that another way to up your walking game is to hit the trails because the rougher terrain requires more effort. If there are no trails near you, opt for a hillier route. 🩺SIGN UP for tips to stay healthy & fit with the top moves, clean eats, health trends & more delivered right to your inbox twice a week💊 According to Dr. Eleazu, another way you can make your walks more challenging is by wearing a weighted vest. This makes the body work harder, which will benefit the heart. 'I believe that any amount of activity has heart health benefits, so if you can't follow the recommendations exactly, try to find ways during the day to take some extra steps,' Dr. Spardo says. 'Use the stairs instead of the elevator, park farther from the entrance to stores or work, take a walk on your breaks and try not to sit in one place for too long.' The more active you are, the more your entire body will benefit—heart included.
