1: Polluted Minds: Air Pollution Exposure Impacts Brain Development  

This longitudinal study analyzed how childhood exposure to air pollution affects brain volume development. Higher exposure to copper and particulate matter (<2.5 μm) during pregnancy and early childhood was associated with smaller hippocampal volumes at age 8. However, as children grew, hippocampal volume showed rapid, compensatory growth. Otherwise, no associations were found between air pollution and volumes of white matter, cortical grey matter, or the cerebellum.

2: Quit While You’re Ahead? Safety of Smoking Cessation during Pregnancy

This retrospective cohort study of 5.2 million live births examined whether smoking cessation therapies used in the first trimester increase the risk of major congenital malformations. Compared with unexposed infants, there were no significant differences in MCM prevalence following exposure to nicotine replacement therapy (37.6 vs 34.4 per 1000 live births), varenicline (32.7 vs 36.6 per 1000 live births), or bupropion (35.5 vs 38.8 live births). These findings are reassuring, given the extensive harms of prenatal smoking.

3: A Closer Look at Postpartum Hemorrhage (PPH)

This systematic review and meta-analysis studied causes and risk factors for PPH — the leading cause of maternal mortality worldwide. Based on data from 327 studies, top causes included uterine atony, genital tract trauma, retained placenta, abnormal placentation, and coagulopathy. Risk factors included anemia, previous PPH, and caesarean delivery.

Mind the Care Gap 🏥

6.5 million people don’t have a family doctor, a sign that Canada’s healthcare system is on life support. Many turn to overcrowded ERs for routine care, while growing gaps in the system fuel the rise of private healthcare. But for patients and doctors alike, will privatization offer relief, or simply deepen the cracks in care?

What is privatization?

Many clinics are privately owned but still bill public health insurance. Meanwhile, public hospitals sometimes offer services patients must pay for, so privatization isn’t black and white. Canada already has a two-tiered system for things like dental care, physiotherapy, and elective surgeries, which are not publicly funded. What’s new is the expansion of private options into traditionally public spaces, like diagnostic imaging and some surgeries.

Today, about 70% of Canadian healthcare is publicly funded, while the rest comes from private insurance or out-of-pocket payments. As more private services pop up, the debate grows louder: is privatization a lifeline for burned-out family doctors — or a shift that leaves public care even more under strain? 

The case for privatization

Privatization can mean shorter wait times and more flexible schedules. Some physicians are drawn to private practice to avoid burnout, set their own hours, and potentially earn more. Dr. Kevin Wang estimates family doctors working in private may earn 30 to 50% more than in public settings, while still offering the same amount of care. Fewer rostered patients can also allow for more time per visit, improving care quality.

Private doctors often bill patients directly instead of going through provincial health plans. While starting an independent clinic is challenging, most physicians join larger private firms, like Telus Health, that provide infrastructure and branding.

The case against privatization

But critics warn that privatization worsens access for those who can’t pay. As private clinics lure physicians away, the public system is left with fewer providers — and often sicker patients who can't afford private fees. Dr. Wang notes some doctors quietly shift to private billing “under the table,” further straining public resources. Going private also means facing overhead costs and negotiating with insurers, which not every doctor is prepared to do.

Family medicine’s squeeze

Of all the specialties facing pressure, family doctors may have it the worst. “Privatization will worsen workforce shortages,” says Dr. Alexandra Ginty, a retired family physician. Already burdened by admin work, many family doctors find additional strain as privatization pushes more responsibilities onto them. Ginty adds that one example of many is how even procedures like plastic surgery are being rerouted to family physicians, as specialists face overwhelming demand. 

As the public system weakens, family doctors are left at the centre of Canada’s healthcare crossroads. It’s a tough spot — stay in a stretched-thin system, or go private for more breathing room (and fewer 10-minute appointments).

Presented by CCFP Ready

Guesswork isn’t evidence-based.

Did you know that in 2021 the NIH published a study stating that students that use more active studying techniques tend to perform better on exams?

At CCFP Ready we took this research to heart and created test resources that are perfected to prepare learners for the family medicine board exam (our materials closely mimic the real test).

We offer practice SAMPs (short answer questions) and SOOs (virtual practice OSCEs) that are marked and created by experienced family doctors. We ensure that our practice tests are up-to-date and tailored to prepare you for the exam day. Don’t leave your exam success to chance — start preparing today with CCFP Ready.

Hot Off The Press

1: 🏜️ Canada’s expansion of medical assistance in dying (MAiD) to include people with non-terminal illnesses is drawing fire from the United Nations. A new report warns the law risks endangering vulnerable groups, particularly people with disabilities — and urges repeal. The UN says these patients should be offered support, not an exit. Health Canada responded, noting that “robust safeguards” are already in place. With public trust and ethics on the line, the pressure is mounting.

2: 🫀 The world’s smallest pacemaker just dropped — and it’s light-activated, dissolvable, and tiny enough to fit in a syringe. Designed for newborns with heart defects, the wireless device sits on the chest, delivers pacing via pulses of infrared light, and dissolves when it’s no longer needed — no surgery required. In preclinical trials, it worked across human donor hearts and multiple animal models.

3: 👩🏻‍⚕️ Independent MLA Elizabeth Smith-McCrossin is sounding the alarm over staffing levels at Nova Scotia hospitals, claiming doctors are leaving due to pay cuts. Community members say it’s disheartening to lose rural physicians. But the province calls those claims false — arguing the new model actually increases wages for family doctors.

4: 💘 Tinder just released Game Game — an AI-powered flirting simulator built with OpenAI’s voice model that scores users on their rizz in roleplay scenarios. It’s meant to be awkward on purpose, but early tests reveal buggy audio, robotic convos, and AI avatars accidentally talking to themselves on Bluetooth speakers. Tinder insists it’s “low-pressure practice,” but right now it’s more glitch than game.

Notable Numbers 🔢

34%: of BC nurses say they’re exposed to weapons at least once a month. A BC Nurses’ Union survey also found 81% have faced verbal or emotional abuse on the job. After 3 assault incidents at Eagle Ridge Hospital since November, security has been increased — but nurses say it’s still not enough.

20%: the lowered dementia risk of older adults who received the Zostavax shingles vaccine. A massive Welsh study found the strongest evidence yet linking shingles vaccination to reduced dementia — especially in women. Researchers say the findings could have major public health implications, even if the mechanism isn’t fully understood.

895: career goals for Alex Ovechkin — officially passing Wayne Gretzky to become the NHL’s all-time leading scorer. The 39-year-old fired a power-play rocket past fellow Russian Ilya Sorokin on Sunday, marking a record-breaking goal 20 seasons in the making. Gretzky called it “truly incredible.”
