Obstructive sleep apnea (OSA) is characterized by repeated airway collapses during sleep and is associated with a lower success rate in in vitro fertilization (IVF) in women with polycystic o***y syndrome (PCOS).

A prospective study at the Beijing Center for Reproductive Medicine included 360 infertile patients with PCOS between 2019 and 2022, who were evaluated using the Home Sleep Apnea Test (HSAT) before initiating fertility treatment.

The prevalence of OSA was 30% in this population, with significantly lower rates of clinical pregnancy and live births after the first embryo transfer cycle compared to those without OSA. Multivariate analysis confirmed that OSA is an independent risk factor for the reduced live birth rate.

This group presented lower levels of anti-Müllerian hormone (AMH) and higher rates of insulin resistance, hyperlipidemia, and metabolic syndrome—endocrine-metabolic alterations that appear to affect ovarian function, endometrial receptivity, and IVF success.

This finding reinforces the importance of diagnosing and treating OSA to improve reproduction.

For years I thought history was built on speeches, wars, and famous names. Today I know that lesson is incomplete. History is also built on silent decisions, on small acts of dignity that never make the headlines.

Pancreatic cancer

Pancreatic cancer is widely considered the deadliest cancer on the planet. By the time it’s discovered, it’s usually already too late.
But a Spanish scientist named Mariano Barbacid may have just cracked the code.

For decades, researchers have known that a mutation in a gene called KRAS is what fuels the cancer’s explosive growth. But doctors labeled it “undruggable.” They insisted it was impossible to stop.

Now, after six relentless years, Barbacid has delivered a breakthrough that defies everything we thought we knew.

His team genetically engineered mice to develop the exact same lethal pancreatic cancer found in humans. Then, they completely eliminated a single enzyme — c‑RAF — that the cancer depends on to survive.

The result was staggering.

The cancer didn’t just slow down… it stopped.

In every mouse treated with this method, the tumors fully regressed. The cancer vanished.

For the first time in history, scientists have witnessed a total remission of advanced pancreatic cancer in a living mammal.

Barbacid cautions that we are still years away from a pill for humans, but he has proven one monumental truth:
This “incurable” disease… might not be incurable after all.
