Treating moms with postpartum depression helps their babies' brains
Psychiatric help for mothers with postpartum depression results in healthy changes in the brains of their babies

(Press-News.org) New research from McMaster University has found that psychiatric help for mothers with postpartum depression results in healthy changes in the brains of their babies.
The study, published in the journal Depression and Anxiety this week, found treating mothers who had postpartum depression with cognitive behavioural therapy (CBT) not only helped the moms, but resulted in adaptive changes in the brains and behaviour of their infants.
More specifically, after the mothers' treatment, their infants showed healthy changes in their nervous and cardiovascular systems, and they were observed to better regulate their behaviours and emotions by both mothers and fathers.
"In fact, we found that after their moms were treated that their infant's brain activity normalized to the levels seen in our healthy infants," said Ryan Van Lieshout, senior author of the study, a psychiatrist, and associate professor of psychiatry and behavioural neuroscience at McMaster's Michael G. DeGroote School of Medicine.
He added that it is well-known that the children of women with postpartum depression have changes in the functioning of their brains that make it more likely that they will develop emotional and behavioural problems later in life. However, it had not been known before if treating the mother's postpartum depression could reverse these changes.
"We believe that this is the first time that anyone has shown that treating moms' postpartum depression can lead to healthy changes in the physiology of the brains of their infants, a finding that we think provides a lot of good news," he said.
"This study shows that cognitive behavioural therapy, a treatment that is short, cost-effective and preferred by women, could potentially reduce the intergenerational transmission of risk from mother to child."
For the study 40 infants of women diagnosed with postpartum depression were matched with 40 infants of non-depressed mothers on infant age, gender and socioeconomic status. The mothers with postpartum depression received nine weeks of group CBT. The infants were all tested before the treatment and nine weeks later, including a questionnaire on the infant behaviour completed by the mother and her partner.

As the number of people who have fought off SARS-CoV-2 climbs ever higher, a critical question has grown in importance: How long will their immunity to the novel coronavirus last? A new Rockefeller study offers an encouraging answer, suggesting that those who recover from COVID-19 are protected against the virus for at least six months, and likely much longer.
The findings, published in Nature, provide the strongest evidence yet that the immune system "remembers" the virus and, remarkably, continues to improve the quality of antibodies even after the infection has waned. Antibodies produced ...

BIRMINGHAM, Ala. - University of Alabama at Birmingham polymer and radionuclide chemists report what they say "may represent a major step forward in microcapsule drug delivery systems."
The UAB microcapsules -- labeled with radioactive zirconium-89 -- are the first example of hollow polymer capsules capable of long-term, multiday positron emission tomography, or PET, imaging in vivo. In previous work, UAB researchers showed that the hollow capsules could be filled with a potent dose of the cancer drug doxorubicin, which could then be released by therapeutic ultrasound that ruptures the microcapsules.
PET imaging with zirconium-89 -- which has a half-life of 3.3 days -- allowed the capsules to be traced in test mice up to seven days. The major ...

NASA-funded research on the 11 largest freshwater lakes in the world coupled field and satellite observations to provide a new understanding of how large bodies of water fix carbon, as well as how a changing climate and lakes interact.
Scientists at the Michigan Tech Research Institute (MTRI) studied the five Laurentian Great Lakes bordering the U.S. and Canada; the three African Great Lakes, Tanganyika, Victoria and Malawi; Lake Baikal in Russia; and Great Bear and Great Slave lakes in Canada.
These 11 lakes hold more than 50% of the surface freshwater that millions of people and countless other creatures rely on, underscoring the importance of understanding how they are being altered by climate change and other factors.
The two Canadian lakes ...

BUFFALO, N.Y. -- In the dark waters of Lake Superior, a fish species adapted to regain a genetic trait that may have helped its ancient ancestors see in the ocean, a study finds.
The research focuses on kiyis, which inhabit Lake Superior at depths of about 80 to over 200 meters deep. These fish, known to scientists as "Coregonus kiyi," belong to a group of closely related salmonids known as ciscoes.
In contrast to three other Lake Superior ciscoes that dwell and feed in shallower regions of water, the kiyis are far more likely to carry a version of the rhodopsin gene that probably improves vision in dim "blue-shifted" waters, ...

Curtin University researchers have uncovered a method of making silicon, found commonly in electronics such as phones, cameras and computers, at room temperature.
The new technique works by replacing extreme heat with electrical currents to produce the same chemical reaction that turns silica into silicon at a reduced economic and environmental cost.
Lead researcher, PhD candidate Song Zhang from Curtin's School of Molecular and Life Sciences said that while the team's discovery was made at the nanoscale, it defines a way of replacing thermochemical processes with electrochemical processes, which ...

With the recent explosive demand for data storage, ranging from data centers to various smart and connected devices, the need for higher-capacity and more compact memory devices is constantly increasing. As a result, semiconductor devices are now moving from 2D to 3D. The 3D-NAND flash memory is the most commercially successful 3D semiconductor device today, and its demand for supporting our data-driven world is now growing exponentially.
The scaling law for 3D devices is achieved by stacking more and more semiconductor layers, well above 100 layers, in a more reliable way. As each layer thickness corresponds to the effective channel length, accurate characterization and control of layer-by-layer thickness is critical. To date, ...

Giant ambush-predator worms, possible ancestors of the 'bobbit worm', may have colonized the seafloor of the Eurasian continent around 20 million years ago. The findings, based on the reconstruction of large, L-shaped burrows from layers of seafloor dating back to the Miocene (23 million to 5.3 million years ago) of northeast Taiwan, are reported in Scientific Reports this week.
Ludvig Löwemark and colleagues reconstructed a new trace fossil, which they name Pennichnus formosae, using 319 specimens preserved within layers of seafloor formed during the Miocene era across northeast Taiwan. Trace fossils are geological features such as burrows, track marks and plant root cavities preserved ...

BOSTON - Four years after patients with melanoma were treated with a personalized cancer vaccine, the immune response kindled by the vaccine remains robust and effective in keeping cancer cells under control, researchers at Dana-Farber Cancer Institute, Brigham and Women's Hospital, and the Broad Institute of MIT and Harvard report in a new study.
The findings, published online today by the journal Nature Medicine, demonstrate the staying power of the immune response generated by the vaccine, known as NeoVax, which works by targeting specific proteins on each patient's tumor cells. The researchers found that, nearly four ...

While it has been reported that opioid overdose deaths have increased during the COVID-19 pandemic, a new study looking at data in Philadelphia showed that this hardship has been overwhelmingly suffered by Black individuals. Researchers from the Perelman School of Medicine at the University of Pennsylvania analyzed the period of time after the city's stay-at-home order was announced in 2020 and showed that, compared to the year before, the number of fatal overdoses suffered by Black individuals spiked by more than 50 percent. At the same time, the rate for white individuals actually fell by 31 percent over the same period. This research ...

PORTLAND, OR - A first-of-its-kind randomized clinical trial found that patients with pancreatic cancer didn't live any longer than expected after receiving pre-operative chemotherapy from either of the two standard regimens, according to trial results published in JAMA Oncology.
While the trial findings did not show a direct patient benefit, they do show that it's possible to safely administer chemotherapy prior to pancreatic cancer surgery. They also pave the way for better treatment testing for this notorious killer. With no symptoms in the early stages, and few effective therapies, pancreatic cancer is the fourth-most deadly cancer type in the United ...
