Teens Oversleeping Post-Concussion May Have Worse Recovery
Kids and teens sleeping longer, even as little as an hour more, during the first week after a concussion were more likely to have worse cognitive and somatic symptoms. Sleeping longer was also linked to persistent symptoms and slower recovery.
METHODOLOGY:
Researchers used data from a randomized clinical trial that took place across three emergency pediatric departments in Ontario, Canada, over a 2-year period beginning in March 2017.
The study included 291 kids and teens between the ages of 10 and 18 years (median age, 13.2 years; 44% female) who received treatment for a concussion within 48 hours of injury.
Each patient wore an accelerometer on their waist 24 hours a day for 2 weeks and completed sleep logs to monitor sleep patterns.
Symptoms were tracked using the Health and Behavior Inventory (HBI), a questionnaire that measures cognitive and somatic symptoms at 1 , 2 , and 4 weeks following their concussion.
Symptom change was measured using conservative (z score ≥ 1.65) and liberal (z score ≥ 1.28) cutoffs; estimates were measured in HBI units.
TAKEAWAY:
Kids and teens who slept 10.5 vs 9.5 hours per night during the first week after a concussion had higher symptom scores at 1 week (estimate, 1.3; 95% CI, 0.25-2.28).
Longer sleep duration was linked to higher odds of persisting symptoms at 4 weeks (conservative: odds ratio [OR], 1.73; 95% CI, 0.91-3.26; liberal: OR, 1.93; 95% CI, 1.07-3.47).
Teens who slept 10.9 vs 9.9 hours were more likely to have increased symptoms at 4 weeks (estimate, 2.2; 95% CI, 0.85-3.47).
IN PRACTICE:
'Long sleep duration may be associated with increased odds of being reliably symptomatic at 4 weeks, therefore a greater risk of PSAC [persisting symptoms after a concussion],' the study authors wrote. 'Clinicians should monitor youths' sleep after concussion.'
SOURCE:
This study was led by Lauren Butterfield, MSc, of the Children's Hospital of Eastern Ontario Research Institute in Ottawa, Canada. It was published online on June 18 in JAMA Network Open.
LIMITATIONS:
The HBI used for symptom assessment is not validated for youths older than 16.99 years, and 16 participants were older than 17 years. Recruitment from three Canadian pediatric emergency departments may have introduced sampling bias.
DISCLOSURES:
Various study authors reported receiving stipend support, research grants, and travel awards from the Children's Hospital of Eastern Ontario Research Institute, the Canadian Institutes of Health Research, and the Canadian Concussion Network, among others.

What a new study suggests about pregnancy diet and type 1 diabetes—and why it's not about being perfect
It's not about being perfect—it's about having the tools to make informed choices. When you're pregnant, it can feel like everything comes with a warning label. And now, a new study adds another layer to the conversation—this time linking a mom's diet during pregnancy to the risk of type 1 diabetes in her child. But before this sparks anxiety over your last bite of pizza or bowl of pasta, let's take a breath—and break down what this research actually means for you and your baby. Because while the study's findings are significant, they aren't meant to shame—they're meant to empower. It's not about being perfect. It's about having the tools to make informed choices. Researchers behind a large-scale Danish study, published in the Journal of Epidemiology & Community Health, analyzed data from more than 67,000 mother-child pairs over a 17-year period. They discovered that when pregnant women ate diets higher in inflammation-promoting foods—like processed meats, sugary drinks, and refined carbs—their children were observed to have a 16% higher risk of developing type 1 diabetes for every one-point increase in the diet's inflammatory score. This does not mean the diet caused diabetes, only that a pattern was observed. This dietary score, called the EDII (Empirical Dietary Inflammatory Index), was calculated using food frequency questionnaires filled out around 25 weeks into pregnancy. Type 1 diabetes is an autoimmune condition—often diagnosed in childhood—where the immune system mistakenly attacks the body's insulin-producing cells. While genetics play a role, the rising number of cases in developed countries suggests that environmental factors, including prenatal exposures, may also be at play. The study also found that high gluten intake and maternal smoking during mid-pregnancy were independently associated with increased diabetes risk in children—pointing to this stage of pregnancy as a potentially critical window for fetal immune development. Related: New study: Cutting sugar in the first 1,000 days could shape your baby's health for life 'Inflammatory' doesn't just mean sugary foods. In this study, higher EDII scores were associated with frequent intake of: Processed or red meats Refined grains (like white bread and pastries) Fried foods Sugary beverages Foods containing trans fats In contrast, lower EDII scores—indicating a more anti-inflammatory diet—were linked to greater consumption of: Leafy greens and cruciferous vegetables Garlic and tomatoes Fruits and whole grains Coffee and tea These food patterns closely resemble the Mediterranean diet, long celebrated for its role in supporting heart health and reducing chronic inflammation. Related: Eating a Mediterranean diet could increase your chances of becoming pregnant, studies show It's easy to read a study like this and feel an onslaught of food guilt. But here's the reality: this isn't about moral judgment—it's about informed awareness. It's also important to remember that many parents whose children develop type 1 diabetes followed healthy or typical diets. Autoimmune conditions are complex, and no one decision during pregnancy can guarantee or prevent an outcome.' Importantly, the researchers emphasized that their findings are observational—meaning they show associations, not direct cause-and-effect. Still, the patterns were strong enough to suggest that diet during mid-pregnancy may have a meaningful influence on the developing immune system. So what can you do with this information? You don't need to toss your cravings out the window or obsess over every ingredient. Instead, you can take small, sustainable steps that feel good to you and your body. If you're pregnant (or planning to be), consider these realistic, non-restrictive shifts: Add before you subtract. Focus on including more fiber-rich, whole foods before worrying about cutting things out. Make swaps where it feels easy. Choose brown rice or quinoa instead of white rice; opt for olive oil instead of butter when you can. Don't stress over every meal. It's what you do most of the time—not all of the time—that matters. Small shifts count. If access to fresh produce or high-quality ingredients is limited, know that every small shift still counts. Frozen vegetables, canned beans, or even simple substitutions like whole-grain bread are powerful steps. Ask for support. A registered dietitian or your OB-GYN can help you personalize your approach based on your cravings, health needs, and energy levels. This study doesn't mean that every food decision during pregnancy needs to be scrutinized or optimized. It means that we're learning more—and that knowledge can be powerful. Especially when it comes from a place of support, not shame. By understanding how inflammation works and how certain foods may influence a child's risk of developing autoimmune conditions like type 1 diabetes, moms can feel more confident making the choices that are right for them. If you're learning this after your pregnancy—or after a diagnosis—it's never too late to apply that knowledge in ways that support your child or future pregnancies. Growth is a sign of strength, not regret. Because you deserve to feel informed, supported—and never judged—for doing the best you can with the knowledge you have.

CFIA confirms Prince Edward Island's 1st case of dermo, in oysters from Egmont Bay
Canadian Food Inspection Agency lab tests have confirmed the presence of the highly damaging mollusc disease dermo in oysters from P.E.I.'s Egmont Bay. "This is the first confirmed case of dermo in P.E.I.," the agency said in a news release issued Friday evening. "Dermo does not pose a risk to human health or food safety, but it can cause increased oyster mortality and decreased growth rates." In a separate email, CFIA also said that tests had confirmed the first cases of both dermo and MSX for the province of Quebec, in oyster samples collected in Chaleur Bay. It's been eight months since what was considered the first detection of dermo in Canadian waters, in oysters from Spence Cove, about five kilometres west of the Confederation Bridge in New Brunswick. Dermo disease or Perkinsosis, caused by a parasite called Perkinsus marinus, had previously been detected in Atlantic waters between Mexico and Maine. It affects both cultured and wild American oysters (Crassostrea virginica). "Outbreaks of Perkinsosis usually occur with warm summer water temperatures above 20 C," a British government fact sheet on the disease says. "Clinical signs may include pale digestive glands, gaping, shrinking of the mantle away from the outer edge of the shell and stunted growth." The CFIA news release said dermo "does not affect other bivalves in this area, including mussels, scallops or clams." Already dealing with MSX News of the positive test results from Egmont Bay will be another blow to the Island's oyster industry, which has been reeling from last July's discovery of MSX, short for multinucleate sphere unknown. That oyster disease was first detected in samples from P.E.I.'s Bedeque Bay, with more cases confirmed in other areas of the province in the months that followed. Like dermo, it affects only oysters and not the humans eating oysters from waters known to have MSX. The Canadian Food Inspection Agency says the parasite that causes dermo is easily transmitted among oysters, mostly when they are between one and three years of age. "Mortality rates are variable but are typically 50 per cent to 75 per cent," the agency says in a factsheet on its website. CFIA has power to limit movement In a statement to CBC News last month, the Canadian Food Inspection Agency acknowledged that it had been asked to test P.E.I. oyster samples for dermo, but said it had no results to share at that time. The agency did go on to outline what would happen if the samples did test positive. If a product in a PCZ [primary control zone] is deemed to be a potential risk, its movement would be controlled. — Canadian Food Inspection Agency "To prevent the spread of dermo or any other animal diseases, the CFIA may establish a primary control zone (PCZ) in areas where a disease is suspected to occur," the statement said. That kind of move would let the agency control how oysters are handled and shipped within and outside the zone. "For example, if a product in a PCZ is deemed to be a potential risk, its movement would be controlled; this means that a permit from the CFIA would be required to move this product within, through and outside of the PCZ," the statement said. "Any new PCZs would be posted as soon as possible on CFIA's website. When a new PCZ is put in place, the CFIA also notifies its provincial partners, stakeholders, Indigenous communities and industry through pre-existing communications channels."
