1: Cracking the Egg Allergy Problem

A cross-sectional study looked at the impact of updated allergy prevention guidelines regarding earlier egg introduction on population prevalence of egg allergy. In 1-year-old infants, the prevalence of egg allergy decreased from 9.2% in 2007-2011 to 7.6% in 2018-2019 (adjusted absolute difference -1.6, [95% CI, -3.3 to -0.005]). These findings suggest that effective implementation of food allergy guidelines can indeed translate to real-world reductions in food allergy prevalence in the population. 

2: It’s Not About When Kids Get a Phone, It’s About How They Use It

A cohort study of ~2000 adolescents found that acquiring a smartphone at age 13 was not associated with depression or obesity, but was associated with poor sleep at age 14 compared to those who had not yet gotten a phone. Greater overall use in those who did acquire phones was associated with depression, obesity and insufficient sleep. Placing the phone outside of the bedroom at bedtime helped combat poor sleep. These results suggest that behavioural interventions may be key to mitigate smartphone use risks in adolescents. 

3: The Bitter Reality of Sugar-Free Diets

An animal model study suggests that completely eliminating sugar may have unintended metabolic consequences. Over a 16-week period, mice on a completely sucrose-free, low-fat diet exhibited poorer glucose control, insulin resistance, and intestinal inflammation compared to a control group consuming a low-fat diet with sucrose.  The sugar-restricted mice also showed significant gut microbiota imbalances and early markers associated with fatty liver disease, despite maintaining a similar body weight to the control group.

Finishing residency is both exhilarating and terrifying. Overnight, the structure falls away and you’re suddenly responsible for decisions that residency never really prepared you for: clinical, professional, and financial.  

Looking back, there are a few financial lessons I wish I had learned earlier. They would have saved me stress, money, and a fair bit of trial and error. If you’re stepping into independent practice, here are the top five things I wish I knew from day 1:

1. Billing Is Far More Important (and Complex) Than Anyone Tells You 

Early on, I underestimated how much money I was leaving on the table simply because I didn’t fully understand billing rules. 

The single most helpful (and painfully boring) thing I eventually did was read the General Preamble of my provincial Schedule of Benefits that most of us never look at.

Beyond self-study, ask mentors, senior colleagues, or your department’s business manager about common billing mistakes. Attend billing education sessions or simply choose a billing provider that offers ongoing support from experienced billing agents for recovering rejections and optimizing claims.

2. If You Don’t Track Your Work, You Can’t Improve It 

In the beginning, focus on clinical care first, but over time, start tracking your own data. Simple metrics like: 

Patterns emerge quickly when you look at your own numbers. You may discover that certain shifts or types of work play to your strengths, or that efficiency changes dramatically depending on context. The more you understand how you work, the more intentional you can be about shaping a practice that fits you. 

3. Insurance Decisions Early On Matter More Than You Think 

As physicians, we’re familiar with liability protection through organizations like the CMPA, but disability insurance is often an afterthought. This is a mistake. 

Locking in disability coverage while you’re young and healthy can protect your assets for decades. Once your health changes, options narrow quickly. 

4. Lifestyle Creep Can Quietly Erase Financial Freedom 

A sudden jump in income makes it incredibly easy to upgrade everything: house, car, travel, lifestyle. The danger isn’t spending, it’s spending too fast. 

Physicians who delay large lifestyle jumps and invest early often gain a massive long-term advantage. Early contributions to RRSPs, TFSAs, and corporate investing benefit enormously from time and compounding. 

5. Taxes Are Your Largest “Expense” and Incorporation Isn’t Always the Answer 

Many new physicians are surprised to learn that marginal tax rates can exceed 50% in provinces like Ontario. Instalments, HST obligations, and deductions add another layer of complexity. 

Incorporation is often discussed too early. A professional corporation can defer taxes and provide flexibility, but its biggest advantages appear once you’re earning more than you need to live on.

A Final Thought: Think Beyond One Income Stream 

Medicine offers incredible opportunities and it’s wise to think long-term. Physician “side gigs” aren’t exit strategies; they’re longevity strategies.

Side projects can safeguard against changes in health or your field, provide additional flexibility, and even reignite your passion for medicine. They give you options… and options matter over a long career.

No one expects you to master finance overnight. But a little attention early on, especially around billing, insurance, taxes, and lifestyle choices can profoundly shape your future. Your career is a marathon, not a sprint. Set it up to last.

1: ⚽ All eyes are on Vancouver as Canada hunts for its 1st-ever World Cup win. Following a historic, hard-fought 1-1 draw against Bosnia-Herzegovina in their tournament opener last week, the co-hosts are getting ready to face Qatar this Thursday at BC Place. Group B is currently locked in a perfect, wide-open deadlock, with all 4 teams sitting at exactly 1 point after Switzerland and Qatar also played to a dramatic 1-1 tie. Analysts heavily favour Canada's attacking depth to overwhelm the Qatari back four on home turf. 

2:🚰 Down it with tap water, not the fancy stuff. A new study found that the liquid you use to swallow your meds can drastically change how well they work. While patients are routinely told to use water, researchers found that trendy alkaline mineral and medicinal waters can prematurely dissolve a pill's protective coating before it hits the right spot in your gut. If standard tap water isn't available, the study surprisingly recommends apple juice, as its natural acidity pairs well with the stomach's environment. Bottom line: skip the high-pH wellness waters when it’s time to take your prescriptions.

3: 🔬 Burn surgeons in Hamilton have successfully saved a Western University student’s face using a revolutionary, world-first treatment. Injured in a severe London, Ont. frat house fire, the 18-year-old became the first person globally to receive an injection of one trillion exosomes, which are microscopic biological particles that signal surrounding cells to rapidly coordinate healing and tissue repair. Thanks to the experimental therapy, which allowed doctors to bypass traditional, invasive skin graft surgery completely, the patient healed at an unprecedented speed with remarkably minimal scarring.

4: 🧃Energy drinks are officially grounded in Quebec. The province has become the 1st jurisdiction in North America to ban the sale of caffeinated energy drinks to anyone under 16. Named the "Zachary Miron Act," the legislation was prompted by the tragic 2024 death of a 15-year-old on ADHD medication who consumed a Red Bull. The law targets drinks with 150 mg/L of caffeine or more, carrying fines up to $62,500 for non-compliance. While the move aims to protect youth from risky heart complications, whether other provinces will follow Quebec’s regulatory buzz remains to be seen.

1.1 trillion: the estimated personal net worth of Elon Musk, who officially became the world’s first-ever trillionaire following SpaceX’s Wall Street debut. Driven by a massive surge in SpaceX stock during its 1st day of trading, Musk's fortune now outstrips the next 5 richest people on Earth combined and eclipses the entire annual economic output of countries like Saudi Arabia and Sweden.

154,000: the number of participants analyzed in a massive BMJ meta-analysis evaluating the true efficacy of routine bone supplements. Reviewing data across 69 clinical trials, researchers found that daily calcium and Vitamin D supplementation provided little to no meaningful protection against fractures or falls for the general aging population.

26%: the reduced likelihood that women with traumatic brain injuries will receive specialized trauma care compared to men. A new decade-long Ontario study of over 55K patients highlights a critical systemic triage bias, revealing that women frequently receive less specialized emergency care despite having identical injury severities.
