đź’Š Drug prices changed fills. But where?

August 27, 2026

Good morning dispensers of wisdom!

If mosquitoes seem to love you while completely ignoring everyone else, it turns out you might just be their type. 🦟 Recently, researchers tested 119 people against 3 mosquito species and found there’s no universal “mosquito magnet.” Instead, each species was attracted to different combinations of human odours and skin bacteria, meaning someone irresistible to one mosquito species might barely register to another. The findings could help researchers better understand how mosquitoes choose their next meal and potentially improve strategies for preventing bites and mosquito-borne disease. So if you’re the only one getting eaten alive at the cottage this weekend, take it as a compliment.

Today’s issue takes 5 minutes to read. Only got 1? Here’s what to know:

  • 💰 Lower drug costs may boost prescription fills

  • 💊 Oral GLP-1 improves HbA1c and weight

  • ⚠️ Hydromorphone Contin 18 mg shortage

  • 💉 Admelog shortage resolved

  • ✈️ Flight crews face higher cancer risk

  • 🤖 AI predicts risk for 348 diseases

Let’s get into it.

Staying #Up2Date 🚨

1: Can Drug Prices Change Whether Patients Fill a Prescription?

A new JAMA Health Forum analysis looked at more than 38,000 prescriptions and found that giving prescribers real-time information on lower-cost alternatives didn’t significantly improve fill rates overall. But for the most expensive drug classes, fill rates jumped 14.5 percentage points, with the biggest gains among patients from lower-income communities. A good reminder that sometimes adherence starts with affordability.

2: An Oral GLP-1 Takes on Insulin-Treated Diabetes

The phase 3 ACHIEVE-5 trial tested oral orforglipron in adults with type 2 diabetes inadequately controlled with insulin glargine. Adding the once-daily GLP-1 receptor agonist produced greater HbA1c reductions and weight loss than placebo over 40 weeks. Orforglipron is still investigational, but an oral, nonpeptide GLP-1 could eventually add another option to the increasingly crowded incretin shelf.

3: A New Treatment Target for Dengue?

A randomized JAMA Network Open trial tested an investigational monoclonal antibody in adults with dengue, a disease that still has no approved specific antiviral treatment. The early-stage study evaluated safety and preliminary efficacy, making this one far from pharmacy shelves, but it offers an interesting glimpse at where dengue treatment could be headed.

The Risk at 35,000 Feet ✈️

Cancer risk at cruising altitude

What happened: A new study found that flight attendants and pilots have a higher risk of dying from radiation-linked cancers, raising questions about what decades spent at cruising altitude may be doing to flight crews.

Why it matters: Ionizing radiation is a known carcinogen, and exposure increases at altitude because there’s less atmosphere shielding people from high-energy cosmic radiation. A JAMA Internal Medicine study analyzed more than 12 million death certificates with occupational information. Of more than 500 occupations examined, flight attendants had the highest proportion of deaths from radiation-related cancers, with pilots close behind.

Compared with the general population, flight attendants had about 50% higher odds of dying from these cancers, while pilots had about 36% higher odds. And radiation may not be the only factor at play.

But: The study still has some extra baggage. It can show an association, not prove cosmic radiation caused the excess cancer deaths, and occupations recorded on death certificates may not always have been accurate. Flight crews also face another potential carcinogenic exposure: years of circadian disruption from irregular schedules and crossing time zones.

And despite the known exposure, the US currently has no federal occupational dose limits or routine radiation-monitoring requirements for aircrew. Canada isn’t much further ahead: Transport Canada recommends airlines track and manage cosmic-radiation exposure, with a suggested annual limit of 20 mSv, but those measures remain voluntary.

Bottom line: The findings add to concerns about the long-term health effects of working at altitude and may give physicians another occupational exposure worth asking about. Researchers say more work is needed to untangle how much of the excess risk comes from cosmic radiation versus other features of life in the air. For doctors with pilots or flight attendants in their practice, “What do you do for work?” may carry a little more weight than it seems.

Hot Off The Press 🗞️

1: 🤖 AI may be getting better at predicting what comes next for your patients. Harvard researchers have developed a machine-learning model that estimates a patient’s risk of 348 diseases using existing health records and genetic risk data. Trained and validated on more than 683,000 patient records, it updates predictions as patients age and outperformed established cardiovascular and breast cancer risk models. It’s only been tested retrospectively, but researchers say it could eventually help physicians spot disease earlier and rethink who gets screened, and when. Curious what made the cut? Check out the full list in the study.

2: 🥬 Food recalls are having quite a summer. In Canada, prepared foods sold at Whole Foods were recently recalled over possible Salmonella contamination, while the US has seen major recalls and outbreaks involving everything from eggs and lettuce to blueberries and jalapeños. It certainly feels like we’re hearing about contaminated food more often, but are foodborne illnesses actually becoming more common? Experts say there’s more going on than meets the eye. So, is our food getting riskier, or are we just getting better at catching it?

3: 🇨🇦 Looking for a clinical trial in Canada just got easier. Health Canada has launched a new Canadian Clinical Trial Search Portal, swapping out its old clinical trials database with a much more searchable tool. Physicians and patients can look for authorized trials by disease, drug, trial status, province, city or approval date, with information on trial locations, eligibility basics and links to fuller registry records. It currently covers drug trials approved since April 2013, and it’s regularly updated with new trials and status changes. Curious what’s recruiting near you? Try the search yourself.
