Good morning!
Few things that can ruin a picnic, a camping trip, or life in a basement apartment faster than bugs. Before you reach for the swatter, though, remember that most insect species are beneficial, or even essential, to healthy ecosystems. A 2019 global analysis found that more than 40% of insect species are in decline, with 1/3 now considered endangered. Wasps, for example, do more than ruin sandwiches. Many feed on aphids, cabbage white caterpillars, and other larvae that would otherwise chew through crops. Even pest control comes with collateral damage: spraying invasive insects can also kill harmless native moths and butterflies. Mosquitoes, though? They're open season. Aim for those little blood-sucking jerks and execute.
Today’s issue takes 5 minutes to read. Only got 1? Here’s what to know:
Reflux care without a pharmacy
Mindfulness shows promise for back pain
Brain injury complicates Alzheimer blood tests
McMaster targets brain metastases earlier
Bleeding powder seals wounds in seconds
Ontario overdose calls surge sharply
Let’s get into it.
Staying #Up2Date 🚨
1: The Reflux Prescription You Can’t Fill at the Pharmacy
A cohort study of 145 patients with laryngopharyngeal reflux found that following an antireflux diet and focusing on stress-reduction activities may be highly effective for reducing symptoms. Strict adherence to a low-fat, low-quick-release sugar, high-protein diet, combined with a wellness activity program, helped tame reflux after 3 months compared to conventional medical therapies, including proton pump inhibitors, antacids, or alginates. The next step to confirm the best way to reduce reflux would be a randomized controlled trial comparing each regimen.
2: Telling Back Pain to Back Off… Virtually?
A randomized controlled trial of 451 patients with chronic low back pain examined the efficacy of a telehealth-delivered mindfulness group for reducing pain intensity. Compared to usual care, patients who attended the group program reported significant improvements in pain, enjoyment of life, and general activity after 6 and 8 weeks. The delivery of the program was also accessible, offering a scalable nonpharmacological option for chronic back pain management.
3: When Brain Injury Muddies the Biomarker Waters
A cross-sectional cohort study looked at how traumatic brain injuries affected the accuracy of Alzheimer disease blood biomarkers. In 272 older veterans, the plasma p-tau217/Aβ42 ratio test was highly accurate in those without TBI history, but significantly less sensitive in those with a history of brain trauma. These findings suggest that brain injury history and severity may influence AD blood test accuracy and should be considered when interpreting results.
Guiding Your Patients to Supportive Mental Health Care
Supporting patients on their path to finding the right therapist can be overwhelming and complex.
Layla Care helps streamline the referral process by thoughtfully matching patients with registered therapists - online or in-person - aligned to their unique needs and preferences.
From a diverse community of 500+ qualified therapists across Ontario, Alberta, British Columbia, and Nova Scotia, patients receive around 2–3 personalized therapist recommendations and typically begin therapy within 1–2 weeks.
To date, Layla has guided more than 25,000 people to therapy and facilitated over 250,000 therapy sessions. On average, patients have rated their quality of care 9.5 out of 10, and the quality of their therapist match a 9.3 out of 10.
Every patient referral is supported by a dedicated Care Coordinator who guides the process, helping connect each person with a therapist who aligns with their goals, preferences, and needs. This personalized, human approach helps ensure patients feel supported throughout their care.
Patients can self-refer at www.layla.care/get-started, or practitioners can directly refer through most EMRs.
The Brain’s New Bodyguard 🧠
Stopping cancer before it spreads to the brain
What happened: Researchers at McMaster University have developed new preclinical drug candidates aimed at stopping cancer cells before they form brain metastases.
Why it matters: Once cancer spreads to the brain, treatment options become limited. The new approach targets inosine monophosphate dehydrogenase 2 (IMPDH2), an enzyme that appears to play a key role in helping lung, breast, skin, and other cancers spread to the brain.
Current treatment for metastatic brain cancer is largely palliative, with about 90% of patients dying within the first year of diagnosis, according to a professor in McMaster’s Department of Surgery. Once cancer cells cross the blood-brain barrier and form tumours, the disease becomes extremely difficult to treat. Radiation can also damage healthy brain tissue, leaving some survivors with lasting cognitive effects.

The McMaster team’s strategy is different: instead of treating brain metastases after they develop, they are trying to prevent them from forming in the 1st place.
The researchers are targeting IMPDH2, which appears to be critical to the cells that initiate brain metastases. IMPDH has been studied previously as a potential cancer drug target, but earlier IMPDH-blocking drugs caused significant side effects because they also affected healthy cells. IMPDH2 may offer a more targeted approach because it is not abundant in healthy tissue and appears to be produced at much higher levels in brain metastasis–initiating cells.
So, what’s next? The research is still in the preclinical stage, but the team has already designed and synthesized several hundred IMPDH2-targeting drug candidates. The goal is to refine the most promising compounds into a treatment that could one day be used in patients at high risk of brain metastases after lung, breast, melanoma, or other cancers.
Human trials have not yet begun, and experts say it could still take years before a drug reaches patients. However, researchers report that their leading candidates already show several characteristics needed for clinical development, including the ability to remain active in the body, cross the blood-brain barrier, and work alongside existing cancer therapies.
Bottom line: This is not a cure for brain cancer. But it represents a potential shift in strategy: rather than waiting for cancer cells to invade the brain and then trying to treat the damage, researchers are working toward stopping that spread before it begins.
Hot Off The Press

1:🩸 Forget gauze and pressure. This powder stops severe bleeding in about 1 second flat, just by reacting with calcium in blood to form an instant hydrogel seal, according to a study published in Advanced Functional Materials. It's made from alginate, gellan gum, and chitosan, and unlike flat patch-style products, it molds itself into deep, irregular wounds and soaks up more than 7 times its own weight in blood. In surgical liver injury models, it beat commercial hemostatic agents on blood loss and time-to-stop, caused no systemic toxicity, and still worked after 2 years sitting in heat and humidity. It started as a battlefield fix and it’s still early-stage animal-model research, but researchers say it's got a shot at civilian ORs and under-resourced emergency settings too.
2: 💉 Health Canada is temporarily allowing the import and sale of a Chinese-aprroved version of ifosfamide to ease a critical shortage of the injectable chemo drug, marking the 1st time it's permitted an exceptional import from a Chinese source. The drug, used to treat soft tissue sarcoma, pancreatic cancer, and cervical cancer, matches the Canadian version in active ingredient, strength, and dosage form, though it requires different (lower) storage temperatures, and Health Canada is asking hospitals to add extra labelling to avoid mix-ups. The shortage isn't just a Canadian problem either, with the European Medicines Agency flagging an ongoing shortage of Baxter's ifosfamide products expected to run into early 2027.
3: 🚨 Opioid overdose calls have risen sharply in 4 Ontario cities compared with last year, according to a CBC analysis. In the first 5 months of 2026, calls were up 20% in Thunder Bay and 199% in Hamilton. Toronto’s non-fatal opioid overdose calls increased nearly 115%, while Ottawa saw a 52% rise in overdose calls overall, including non-opioid cases. Researchers and harm-reduction workers point to several possible factors, including a more toxic drug supply — with substances such as medetomidine, a veterinary sedative, increasingly detected — and the closure of some supervised consumption sites. Ontario says it is investing $560 million in 29 abstinence-based HART Hubs as part of a shift in its approach to addiction care.
4: 🌎 Soundgarden’s “Black Hole Sun” may not be the scientifically accurate prediction we once thought. Scientists have long predicted that in roughly 5 billion years, the Sun will expand into a red giant before eventually becoming a white dwarf — a process that was expected to destroy Earth. Now, new research published in Astronomy & Astrophysics suggests our planet may survive the Sun’s transformation if the Sun loses enough mass and Earth’s orbit drifts farther outward. The models still carry uncertainty, especially around how the dying Sun will evolve, but for now, the theory suggests one thing: Earth is a fighter.
