Driving these numbers: This past week saw the US and CA indices hit their all-time highs again due to tech being back in full swing. We expect good news to continue rolling, as Apple, Alphabet, Microsoft, Amazon, and Meta all release their earnings (and cost-cutting measures). Non-tech sectors are still growing, but are a bit below their all-time highs.

The Rexulti Code🕵️🖼️

Guess who’s got a new gig? Health Canada just threw Rexulti (brexpiprazole), the multitasker for schizophrenia and depression, into the ring to tackle agitation in Alzheimer’s patients.

What happened: Cooked up by Otsuka Pharmaceutical Canada Inc. and Lundbeck Canada Inc., Rexulti got the green light after three 12-week randomized studies. With agitation affecting half of Alzheimer’s patients, manifesting as pacing, gesturing, shouting, and hitting, Rexulti is now approved for treating aggressive agitation resistant to non-pharmacological approaches. It’s a once-daily prescription with common side effects: headaches, urinary tract infections, and sleep disturbances.

Why it’s interesting: Greenlighting Rexulti for agitation is a game-changer, given the issue’s limited options. The approval could also open doors for future meds targeting Alzheimer’s psychiatric symptoms.

This becomes crucial with a recent ASC study highlighting a rise in "young-onset dementia.” By 2050: a projected 187% spike, hitting 40,000 under-65 folks dealing with dementia in Canada, with 273% for Indigenous communities. As for why, more research needs to be done.

Rexulti, a miracle pill?: Pause. In May 2023, the FDA gave the nod for our US pals, but the BMJ questions its benefits. 

• Clinical trials showed agitation symptoms with a 5.3-point difference on a 174-point scale (vs. 17 points experts consider indicative of real-world change). 

• Death risk spiked 4x vs. a placebo over 16 weeks. 

• The BMJ hinted the FDA might’ve lowered their standards on Rexulti.

Otsuka argued it's safer than its antipsychotic alternatives. But with $1 billion in sales at stake, the BMJ thinks maybe commercial interests talk louder than science.

Bottom line: As of now, Public Citizen Health says Rexulti's perks don't outweigh safety concerns. But if Postcall’s last issue on antibiotics is any hint, an unprepared 2050 might be the new 2012🌋.

Things your attending might pimp you on 🙋🏽‍♀️👨‍⚕️ 

1. GAS me up! 

JK! — getting a Group A Strep (GAS) infection is the last thing anyone needs right now. While GAS is typically associated with strep throat, a much more severe, systemic version of the illness known as invasive GAS (iGAS) is on the rise. Over 4,600 cases were recorded in Canada in 2023, raising alarm bells from Northern Ontario to BC, where four children have died from iGAS. The recent spike in cases may be related to the seasonal flu epidemic given that viruses can precede and facilitate invasive disease. However, the possibility of a more aggressive strain of GAS remains. 

2.  Guideline watch  👀

The American Gastroenterology Society has a new clinical practice guideline for using vasoactive agents and IV albumin in cirrhosis. Here’s a roundup of the relevant takeaways: 

• Initiate vasoactive drugs (octreotide) as soon as you suspect variceal hemorrhage and preferably before endoscopy. Continue for 2 to 5 days to prevent rebleeding.

• Give IV albumin at the time of large-volume (>5 L) paracentesis, but not for uncomplicated ascites. IV albumin can be considered in patients with SBP. 

• IV albumin is the volume expander of choice in hospitalized patients with cirrhosis and ascites who present with AKI.

3. Gabapentin? More like gaba-pantin’

A retrospective cohort study with over 10,000 participants has found that gabapentinoids are associated with severe COPD exacerbation. Gabapentinoid use was associated with significantly higher risk for severe COPD exacerbations requiring hospitalization (15.1% vs. 8.3% annually; adjusted hazard ratio, 1.4). New users of gabapentinoids also had significantly higher risks for respiratory failure (5.7% vs. 3.6% annually, aHR, 1.3) and moderate-to-severe COPD exacerbations (53% vs. 29% annually; aHR, 1.1). Gabapentin did not differ from pregabalin in risk for severe COPD exacerbations. This comes after a 2019 FDA warning about gabapentinoids causing breathing difficulties. 

The Doctor (and their scribe) Will See You Now 👩🏻‍⚕️ 🖥️

What happened? Some doctors say they’re fed up with spending more time taking illegible notes than listening to patient’s concerns.

Maybe they didn’t say exactly that, but 42% of doctors did say paperwork burnout makes them want to quit clinical practice. Lucky for them, companies like Microsoft and Amazon have created AI tech that can help reduce fatigue and increase productivity.

Why it’s interesting: Tools like Innovaccer and IRIS have the ability to transcribe, analyze, and summarize conversations between doctors and patients. The conversation is then converted into a “provider template” where it creates a list of tasks for the patient’s treatment. Before the information is filed, it’s reviewed by trained specialists and clinicians to ensure patient accuracy for doctor approval.

Like lab coats, one size does not fit all, and the same can be said about this new tech. While many doctors agree that the use of a transcriber can improve overall care, the fear of the “black box effect,” which occurs when AI produces results or advice without explanation, have some physicians second-guessing their decision to use the tech. This issue might cause doctors to misdiagnose a patient, or misunderstand the patient’s needs – as it can be difficult to trace the system’s thought processes.

Bottom line: Transcriber tools can be useful to alleviate doctors' heavy workload, but you shouldn’t start chanting “no more pencils, no more books” yet! Doctors and AI must work together in order to defeat their common enemy… paperwork. 

🍔 Quick Bites

1: 🧠 The future is… last weekend? According to X, the first human successfully received a Neuralink implant over the weekend. Though the “initial results show promising neuron spike detection,” Elon Musk added no more details about the patient.

2: 🎾 Jannik Sinner rallied from two sets down to win the men’s Australian Open final over Daniil Medvedev — his first grand slam title. (It probably won’t be his last.)

3: 🌿 Bayer has been ordered to pay $2.25B USD in the latest trial concerning its weedkiller, Roundup. The plaintiff said he developed non-Hodgkins lymphoma as a result of using Roundup for yard work at his house for several years.

4: 🏅 Almost two years after the Beijing 2022 Winter Olympics, Russian figure skater Kamila Valieva will be disqualified due to doping — including TMZ (used to treat angina).

5: 🦟 Last week, RTS,S — the world’s first malaria vaccine — began to roll out in routine immunizations for babies and children under 5 in Cameroon. According to WHO, the vast majority of malaria deaths worldwide occur in Africa, and kids under 5 are at high risk.

6: 👶🏽 A new study says that babies exposed to COVID in the womb are 3x more likely to develop respiratory distress. Infants whose mother received at least one dose of an mRNA vaccination were 67% less likely to suffer serious breathing problems, compared to unvaccinated mothers.

7: ⚠️ The government is looking to delay the expansion of MAID to cover those suffering solely from mental illnesses. Health Minister Mark Holland says, "Although the guidelines are set, there has not been enough time for people to be trained on them.”

❓Trivia Answer❓

Because of the apothecary system. This system of weights and measures came from England and France during the early Middle Ages. The base weight was the weight of a grain of barleycorn, or 64.8 mg. Aspirin was 5 grains (gr.) or 325 mg. But then, why Tylenol? It’s just following aspirin. 🤷‍♀️
