Antidepressant use in pregnancy tied to affective disorders in offspring; no causal link
2021-04-12
(Press-News.org) New York, NY - Major depressive disorder is highly prevalent, with one in five people experiencing an episode at some point in their life, and is almost twice as common in women than in men. Antidepressants are usually given as a first-line treatment, including during pregnancy, either to prevent the recurrence of depression, or as acute treatment in newly depressed patients. Antidepressant use during pregnancy is widespread and since antidepressants cross the placenta and the blood-brain barrier, concern exists about potential long-term effects of intrauterine antidepressant exposure in the unborn child.
Using the Danish National Registers to follow more than 42,000 singleton babies born during 1998-2011 for up to 18 years, researchers at the Icahn School of Medicine at Mount Sinai investigated whether exposure to antidepressants in the womb would increase the risk of developing affective disorder like depression and anxiety in the child. In a study published April 5 in Neuropsychopharmacology, the scientists found that children whose mothers continued antidepressants during pregnancy had a higher risk of affective disorders than children whose mothers stopped taking antidepressants before pregnancy. However, to understand whether the underlying disorder for which the antidepressant was given or the medication itself was linked to the child's risk of developing an affective disorder, they also studied the effect of paternal antidepressant use during pregnancy and similarly, found that children of fathers who took antidepressants throughout pregnancy had a higher risk for affective disorders. Thus, the research team speculates that rather than being an intrauterine effect, the observed link is most likely due to the parental mental illness underlying the antidepressant use.
"Approximately half of women who use antidepressants before pregnancy decide to discontinue use either before or during pregnancy due to concerns about the negative consequences for their child," said Anna-Sophie Romel, PhD, an instructor in the Department of Psychiatry at Icahn Mount Sinai and first author of the paper. "Our study does not provide evidence for a causal relationship between in-utero exposure to antidepressants and affective disorders in the child. So, while other long-term effects of intrauterine exposure to antidepressants remain to be investigated, our work supports antidepressant continuation for women with severe symptoms or a high risk of relapse because untreated psychiatric illness during pregnancy can have negative consequences on the health and development of the child. Women and their health care providers should carefully weigh all of the treatment options and jointly decide on the best course of action."

Stress alters brain activity in self-inhibition areas yet doesn't trigger binge-eating, according to new research published in JNeurosci.
People who binge-eat, a hallmark symptom of several eating disorders, can feel out of control and unable to stop, and often binge after stressful events. This led scientists to theorize stress impairs the brain regions responsible for inhibitory control -- the ability to stop what you are about to do or currently doing -- and triggers binge-eating.
Westwater et al. tested this theory by using fMRI to measure the brain activity of women with anorexia, bulimia, or without ...

A unique residential study has concluded that, contrary to perceived wisdom, people with eating disorders do not lose self-control - leading to binge-eating - in response to stress. The findings of the Cambridge-led research are published today in the Journal of Neuroscience.
People who experience bulimia nervosa and a subset of those affected by anorexia nervosa share certain key symptoms, namely recurrent binge-eating and compensatory behaviours, such as vomiting. The two disorders are largely differentiated by body mass index (BMI): adults affected by anorexia nervosa tend to have BMI of less than 18.5 kg/m2. More than 1.6 million people in ...

In a new study published in Cell Stem Cell, a team led by USC Stem Cell scientist Michael Bonaguidi, PhD, demonstrates that neural stem cells - the stem cells of the nervous system - age rapidly.
"There is chronological aging, and there is biological aging, and they are not the same thing," said Bonaguidi, an Assistant Professor of Stem Cell Biology and Regenerative Medicine, Gerontology and Biomedical Engineering at the Keck School of Medicine of USC. "We're interested in the biological aging of neural stem cells, which are particularly vulnerable to the ravages of time. This has implications for the normal cognitive decline that ...

Researchers have used a technique similar to MRI to follow the movement of individual atoms in real time as they cluster together to form two-dimensional materials, which are a single atomic layer thick.
The results, reported in the journal Physical Review Letters, could be used to design new types of materials and quantum technology devices. The researchers, from the University of Cambridge, captured the movement of the atoms at speeds that are eight orders of magnitude too fast for conventional microscopes.
Two-dimensional materials, such as graphene, ...

New research from McMaster University suggests the pandemic has created a paradox where mental health has become both a motivator for and a barrier to physical activity.
People want to be active to improve their mental health but find it difficult to exercise due to stress and anxiety, say the researchers who surveyed more than 1,600 subjects in an effort to understand how and why mental health, physical activity and sedentary behavior have changed throughout the course of the pandemic.
The results are outlined in the journal PLOS ONE.
"Maintaining a regular exercise program is difficult at the best of times and the conditions surrounding the COVID-19 pandemic ...

A new algorithm can predict which genes cause cancer, even if their DNA sequence is not changed. A team of researchers in Berlin combined a wide variety of data, analyzed it with "Artificial Intelligence" and identified numerous cancer genes. This opens up new perspectives for targeted cancer therapy in personalized medicine and for the development of biomarkers.
In cancer, cells get out of control. They proliferate and push their way into tissues, destroying organs and thereby impairing essential vital functions. This unrestricted growth is usually induced by an accumulation of DNA changes in cancer ...

In the earliest stage of life, animals undergo some of their most spectacular physical transformations. Once merely blobs of dividing cells, they begin to rearrange themselves into their more characteristic forms, be they fish, birds or humans. Understanding how cells act together to build tissues has been a fundamental problem in physics and biology.
Now, UC Santa Barbara professor Otger Campàs, who also holds the Mellichamp Chair in Systems Biology and Bioengineering, and Sangwoo Kim, a postdoctoral fellow in professor Campàs lab, have approached this question, with surprising findings.
"When you have many cells physically interacting with each other, how does the system behave collectively? What is the physical state of the ensemble?" said ...

Evidence is growing that health care delivered by teams is superior to services delivered by a single practitioner. Published in the Journal of the American Board of Family Medicine -- University of Minnesota, University of North Carolina, American Board of Family Medicine and the American Academy of Family Physicians researchers compared key elements from the practice of a pharmacist providing comprehensive medication management to the foundational components defined for primary care.
Based on a common health care team framework -- the Four C's of Primary Care (first contact, continuity, comprehensiveness, and coordination) -- this team ...

UNIVERSITY PARK, Pa. -- When the COVID-19 pandemic hit in early 2020, many families found themselves suddenly isolated together at home. A year later, new research has linked this period with a variety of large, detrimental effects on individuals' and families' well-being and functioning.
The study -- led by Penn State researchers -- found that in the first months of the pandemic, parents reported that their children were experiencing much higher levels of "internalizing" problems like depression and anxiety, and "externalizing" problems such as disruptive and aggressive behavior, than ...

Young scientists from NUST MISIS have presented multilayer antibacterial coatings with a prolonged effect and a universal spectrum of action. The coating is based on modified titanium oxide and several antiseptic components. The coatings can be used in modern implantology as a protective layer for the prevention of concomitant complications - inflammation or implant rejection. The results of the work have been published in the international scientific journal Applied Surface Science.
Antibacterial coatings are currently being actively researched, as the search for alternatives to traditional antibiotics is growing. They can be applied to implants, thereby preventing inflammation caused by nosocomial infections.
Nevertheless, the creation of antibacterial, but at the same time biocompatible ...
