WHO issues new guidelines expanding contraceptive options

Extended-use pills, longer-lasting implants and mifepristone as emergency contraception are now recommended.

The World Health Organization published guidelines on 23 September 2026 recommending a broader range of contraceptive methods, including combined pills usable continuously for up to a year and implants effective for up to five years. It also recommends mifepristone as emergency contraception within five days of unprotected sex. WHO estimates 164 million women who want to avoid pregnancy are not using contraception.

What holds up

✓The guideline publication and date are confirmed on WHO's website.
✓The 164 million unmet-need figure is WHO's own estimate.

What doesn't yet

?Safety and effectiveness claims for low-dose mifepristone rest on WHO's own evidence review.
?Real-world rollout in low-resource settings is an aspiration, not a documented outcome.

Ask before you share

→How quickly will national health systems adopt the recommendations?
→Will regulators approve mifepristone for emergency contraception?
→What barriers — cost, stigma, supply — will limit uptake?

Multi-cancer blood test boosts early detection 6.5-fold in a large study

PATHFINDER 2 results, published in Nature Medicine, support GRAIL's Galleri test ahead of an FDA advisory review.

Oregon Health & Science University researchers published PATHFINDER 2 results on 22 September 2026 showing GRAIL's Galleri test substantially increased cancer detection when added to standard screening. The findings appeared in Nature Medicine and were due to be presented to an FDA advisory committee. The test looks for signals of more than 50 cancer types in cell-free DNA.

What holds up

✓Publication in Nature Medicine and the lead author are confirmed by OHSU.
✓An FDA advisory committee review was scheduled after the study's release.

What doesn't yet

?The '6.5-fold' figure is the study's own result and has not yet been assessed by regulators.
?Performance in more diverse, real-world populations is unresolved.
?GRAIL, the manufacturer, has a commercial interest in favorable results.

Ask before you share

→Will the FDA panel endorse approval?
→How will the test perform in groups with different risk profiles?
→What will it cost, and who will be able to access it?

DR Congo Ebola toll passes 3,700 as health workers strike

WHO says the outbreak remains uncontrolled, with cases rising sharply in North Kivu even as other provinces improve.

WHO said on 24 September 2026 that DR Congo's Ebola outbreak had reached 7,773 confirmed cases and 3,759 deaths, citing government figures. Cases fell 26% in Ituri and 15% in Haut-Uele from 31 August to 20 September, but rose 73% in North Kivu, where a health workers' strike is hampering the response.

What holds up

✓WHO officials confirmed the totals and the diverging provincial trends.
✓A strike and insecurity were cited as constraints in North Kivu.

What doesn't yet

?That the outbreak will surpass the 2014–16 West Africa epidemic is a projection.
?The share of deaths in communities versus treatment centers rests on partial surveillance.

Ask before you share

→What is being done to end the health workers' strike?
→Why has North Kivu diverged so sharply from other provinces?
→Is international funding enough to reverse the trend?

Ask before you share

→What was vaccine coverage before the outbreak, and what catch-up is planned?
→Which areas and groups are hit hardest?

French study links common food preservatives to higher blood pressure

Eight widely used additives were associated with hypertension and heart disease in a large observational study.

Researchers at INSERM and Paris universities, led by Mathilde Touvier, published in the European Heart Journal an analysis of long-term preservative exposure, finding eight preservatives associated with higher rates of hypertension and cardiovascular disease.

What holds up

✓Published in the European Heart Journal by named INSERM-affiliated researchers.
✓The authors describe it as observational — associations, not proven causes.

What doesn't yet

?That these preservatives cause hypertension is not established, by the authors' own account.
?Exposure levels needed for harm are not detailed in coverage.

Ask before you share

→Which confounders were controlled for?
→Which foods account for most exposure?
→Should regulators act before causal evidence exists?
