Psilocybin may make postpartum depression worse, study finds

Published

on

Psilocybin may heighten anxiety and depression in new mothers rather than help treat postpartum mental health conditions, research suggests.

Scientists found that giving mouse mothers the psychedelic drug – the active compound in magic mushrooms – increased anxiety and depressive-like behaviour linked to perinatal mood disorders, which are mental health conditions that can develop during or after pregnancy.

The results challenge assumptions about psilocybin’s therapeutic use, indicating it may not be suitable for all patient groups.

David E. Olson, director of the IPN and professor of chemistry, biochemistry and molecular medicine at UC Davis, said: “The IPN has done a lot of work demonstrating that a single dose of a psychedelic can lead to long-lasting, beneficial effects.

“But it’s a little more nuanced than that in terms of who can really benefit and who might be at risk.

“There are different patient populations.”

Researchers at the University of California, Davis Institute for Psychedelics and Neurotherapeutics tested the drug in a mouse model of postpartum depression.

In this model, mothers could escape into a separate cage, mimicking the infant avoidance seen in human postpartum depression.

The negative effects persisted for two weeks after a single dose.

More concerning, pups raised by psilocybin-treated mothers also showed anxiety and depression-like symptoms into adulthood, suggesting harmful effects were passed on through lactation and altered brain development.

Co-author Danielle Stolzenberg, associate professor of psychology at UC Davis, said: “One of the things that’s discussed consistently in the clinical literature is that mums often feel like they have trouble bonding with their infants when they’re experiencing depressive symptoms.

“The mouse mums in the social stress paradigm spend significantly more time in the cage without the pups.

“They will often run back and forth to check on them but tend to actively avoid their infants for long periods of time.”

The team had expected positive results given psilocybin’s reported benefits for other mental health conditions.

“Psilocybin was of such interest for us because it’s been demonstrated to be useful across a whole host of mental disorders, including addressing anxiety and depression,” said first author Cassandra Hatzipantelis, a postdoctoral fellow at the IPN.

“We thought it could have the ability to address things that go wrong in postpartum depression, like the parent-infant connection.”

Instead, the mouse mothers continued to avoid their offspring and showed persistent symptoms even after separation.

Psilocybin-treated mice were also at higher risk of behavioural impairments and depressive-like symptoms.

Nine weeks after weaning, both male and female offspring showed heightened anxiety and depression compared with control groups.

Their brains also contained traces of psilocin, the metabolite produced when the body processes psilocybin.

“We now know that even low doses of exposure can impact offspring for long periods of time,” Stolzenberg said.

“These could be really important therapeutics, but we also realise they have limitations, and we have to conduct rigorous science to understand what those limitations are,” Olson added.

AstraZeneca drug approved for breast cancer in EU

Published

on

AstraZeneca’s breast cancer drug Etcamah has been approved in the EU as part of a combination treatment for advanced disease.

The European Commission acted on a positive opinion from the Committee for Medicinal Products for Human Use, the Cambridge, England-based drug maker said.

The decision followed positive results from the Serena-6 phase III trial, which showed a 56 per cent reduction in the risk of disease progression in advanced oestrogen receptor-positive breast cancer.

A phase III trial is a large, late-stage study used to assess a treatment’s safety and effectiveness before wider regulatory approval.

Oestrogen receptor-positive breast cancer is a form of the disease that can grow in response to the hormone oestrogen.

Etcamah, whose generic name is camizestrant, was tested in combination with a cyclin-dependent kinase 4/6 inhibitor.

Known as CDK4/6 inhibitors, these medicines block proteins that help cancer cells grow and divide.

AstraZeneca said the Etcamah combination has also been approved in Japan, the UAE and Saudi Arabia based on the Serena-6 trial results.

The company said breast cancer remains the leading cause of cancer death among women in Europe, with more than 140,000 deaths and more than 540,000 patients diagnosed in 2024.

AstraZeneca shares were down 0.6 per cent at 12,628 pence in London on Thursday.

From Hologic to Ark Surgical: Why Joseph LaBruzzo is betting on the future of women’s surgical innovation

Published

on

After more than two decades leading organisations at some of the world’s most respected medical device companies, including Hologic, SenoRx Breast Care, and BTL Industries, Joseph B. LaBruzzo is embarking on a new chapter as President & CEO of U.S. Operations and Board Member at Ark Surgical.

We sat down with Joseph to discuss what drew him to Ark Surgical, why he believes women’s surgical innovation is entering a transformative era, and what it takes to bring meaningful technologies from concept to standard of care.

You have held leadership positions at some of the biggest names in MedTech. What attracted you to Ark Surgical?

Throughout my career, I’ve been fortunate to work with organisations that developed technologies capable of changing the standard of care.

What attracted me to Ark Surgical is the opportunity to help address a meaningful unmet need in gynecologic surgery with an innovation that has the potential to improve patient outcomes while preserving the benefits of minimally invasive surgery.

Opportunities like that don’t come along very often.

FemTech World recently highlighted that many women remain unaware of gynecologic cancers and that unexpected diagnoses continue to have a profound impact on patients and families.

How has your own experience shaped the way you think about innovation in women’s health?

Earlier in my career, I witnessed many women receive life-changing cancer diagnoses.

Those experiences stayed with me and reinforced my belief that if there’s an opportunity to reduce risk through better innovation, it’s one worth pursuing.

That’s one of the reasons I was drawn to Ark Surgical.

The vast majority of minimally invasive gynecologic procedures are performed for conditions believed to be benign. Unfortunately, in rare cases, pathology later reveals an unexpected malignancy.

LapBox was designed with a proprietary dual-wall tissue containment system to help facilitate contained specimen retrieval and minimise the risk of tissue spillage during laparoscopic procedures.

I believe innovations like this can help surgeons manage the unexpected while preserving the many benefits of minimally invasive surgery for women.

Women’s health has gained significant momentum in recent years, yet surgical innovation often receives less attention than diagnostics or therapeutics. Why do you think that is?

Women’s health has historically been underfunded and underserved across many areas of medicine, and surgery is no exception.

While we’ve seen tremendous advances in diagnostics and pharmaceuticals, there are still important opportunities to improve the surgical experience for both physicians and patients.

Innovation that enhances safety, efficiency, and outcomes has the potential to make a lasting impact.

What excites you most about LapBox?

LapBox addresses a very real challenge that gynecologic surgeons face during minimally invasive procedures.

It was thoughtfully designed to integrate seamlessly into the surgical workflow while providing an added layer of confidence when tissue retrieval is required.

I believe technologies that solve real clinical challenges in a practical way have the greatest potential to become part of the standard of care.

What do you see as the biggest unmet needs in minimally invasive gynecologic surgery today?

The future of surgery isn’t simply about making procedures less invasive. It’s about making them smarter and safer.

Surgeons need technologies that integrate seamlessly into their workflow while helping them navigate increasingly complex clinical situations.

Every advancement that helps reduce risk while preserving the benefits of minimally invasive surgery has the potential to improve outcomes for both physicians and patients.

That’s where I believe the greatest opportunities for innovation exist.

As you take on this new role, what are your priorities over the next 12 months?

Our focus over the next 12 months is to build a strong foundation for growth. That means expanding physician partnerships, driving early clinical adoption, growing our team, and ensuring that more surgeons have access to technologies like LapBox.

At the same time, we’re focused on building strategic relationships with investors, healthcare systems, and industry partners that support our long-term vision.

What advice would you give entrepreneurs building the next generation of women’s health companies?

Start with a real clinical problem and never lose sight of the patient.

Great technology alone isn’t enough. You also need strong clinical evidence, physician advocates, and a clear market strategy. The companies that succeed are the ones that bring all of those pieces together while remaining focused on improving patient care.

Pregnancy complications may increase risk for artery disease, study finds

Published

on

Pregnancy complications may increase women’s risk of peripheral artery disease later in life, new research suggests.

The study analysed data from more than two million women in Sweden who gave birth to single babies between 1973 and 2015.

Led by Casey Crump, the research examined the long-term risk of peripheral artery disease among women who experienced preterm delivery, pre-eclampsia, gestational diabetes or other adverse pregnancy outcomes.

Crump, professor in the department of family and community medicine at McGovern Medical School at UTHealth Houston, said: “Our prior work has already shown that adverse pregnancy outcomes are associated with long-term risks of heart disease, stroke, and heart failure.

“This study builds on that work by showing that these women have an increased risk of peripheral artery disease, an important but understudied cardiovascular condition.”

Peripheral artery disease is often a precursor to long-term cardiovascular complications, including stroke, ischaemic heart disease and premature death.

The condition affects millions of people worldwide and occurs when narrowed arteries reduce blood flow, most commonly to the legs and feet.

Ischaemic heart disease occurs when the heart does not receive enough blood and oxygen, usually because the arteries have narrowed.

Symptoms of peripheral artery disease can include leg pain, cramps while walking, numbness, cold feet and sores on the feet or legs that are slow to heal.

Crump said women who experience pregnancy complications have an important opportunity after giving birth to make plans with their primary care doctor to monitor long-term risks.

Women who have experienced complicated pregnancies should speak with their doctor about possible future cardiovascular health risks.

Checks for blood pressure, diabetes and cholesterol are important.

While the period after childbirth is an important time for women to monitor their health, Crump said it is never too late to lower the risk of peripheral artery disease.

He said: “Women with a history of adverse pregnancy outcomes who seem to be doing well may still have a higher risk that can emerge later in life.”

Crump also suggested preventive steps such as avoiding smoking, maintaining a healthy weight and following a healthy lifestyle.

He stressed the importance of long-term follow-up care and conversations with healthcare providers to help protect cardiovascular health later in life.
