    Genome-wide association studies of coffee intake in UK/US participants of European ancestry uncover cohort-specific genetic associations

    Researchers are interested in understanding the biology of why some people are more likely to overconsume substances. Some substances are difficult to study—people might not admit to illegal substance abuse or to how much alcohol they drink. But Americans are more likely to accurately recall and share how much coffee they drink—which is related to how much caffeine they consume. And so a team of researchers paired up with the company 23 and Me to try to understand genetic differences among a large set of people, to try to tease out any genetic similarities that could be correlated with coffee consumption. Sandra Sanchez-Roige is an associate professor in the department of psychiatry at the University of California San Diego, and she’s one of the study’s authors. Abraham Palmer is a professor and vice chair of basic research in the department of psychiatry at UC San Diego, and he’s another of the study’s authors.  Read their full study here: https://www.nature.com/articles/s41386-024-01870-x Hosted on Acast.

    C-reactive protein moderates associations between racial discrimination and ventromedial prefrontal cortex activation during attention to threat in Black American women

    Scientists have been amassing an increasing amount of evidence about the impact of racial discrimination and racial trauma, including how it can have an impact on brain regions involved with threat vigilance and emotional regulation. At the same time, there’s evidence that increased engagement in those areas has been linked to increased risk of mental health problems like depression, and they also suspect it could be a vulnerability for brain health issues such as dementia and Alzheimer’s disease.  Negar Fani is an associate professor in the department of psychiatry and behavioral sciences at Emory University School of Medicine, and she worked with Aziz Elbasheir, a PhD candidate at Emory University in the neuroscience program, on the study. They knew that C-reactive proteins, or CRPs, are a marker of immune activation in the blood. Read their full study here: https://www.nature.com/articles/s41386-023-01737-7 Hosted on Acast.

    Ghrelin decreases sensitivity to negative feedback and increases prediction-error related caudate activity in humans, a randomized controlled trial

    There’s a hormone called ghrelin that’s secreted in the stomach, and when someone is hungry it contributes to that feeling of hunger and the need to search for food. But neurological studies have suggested that ghrelin might also play a role in compulsivity and impulsivity, and it might be related to substance use disorders. Rebecca Boeme is an assistant professor at Linkoping University in Sweden. She and her colleagues decided to use human subjects to investigate how ghrelin affects reinforcement learning, basically how ghrelin influences decision making when subjects receive positive and negative feedback —and also how it might actually be affecting the brain.  Read the full study here: https://www.nature.com/articles/s41386-024-01821-6 Hosted on Acast.

    Spotlighting SHAPERS: Sex hormones associated with psychological and endocrine roles

    Dr. Nicole Petersen is an assistant professor in the department of psychiatry and behavioral sciences at UCLA. Her commentary is a new paper in the journal Neuropsychopharmacology, called “Spotlighting SHAPERS: sex hormones associated with psychological and endocrine roles.” Dr. Petersen starts the paper describing an unnamed signaling molecule that can affect the physical structure of the brain and that seems to be related to a wide number of psychological and neurological conditions. Then she reveals that this is estradiol. The point she makes in the paper is that estrogen isn’t the only neuroactive substance that affects the brain in ways that we just don’t understand.

    Comparable roles for serotonin in rats and humans for computations underlying flexible decision-making

    Serotonin is a critical chemical when it comes to a number of psychiatric conditions, such as OCD, where it seems to play a particular role in cognitive flexibility. That is, serotonin levels are related to the fact that someone is perseverating on intrusive thoughts or compulsions and isn’t able to be as flexible as otherwise would be necessary. Trevor Robbins, professor of cognitive neuroscience at the University of Cambridge, is one of the authors of a recent study titled Comparable roles for serotonin in rats and humans for computations underlying flexible decision-making, and he says such cognitive flexibility also plays a role in depression and schizophrenia.

    Integrating public health and translational basic science to address challenges of xylazine adulteration of fentanyl

    The drug naloxone, otherwise known as Narcan, is a critical tool in reversing fentanyl overdoses and reducing mortality. But now fentanyl is appearing on the streets adulterated with a drug called xylazine.  Justin Strickland, assistant professor at Johns Hopkins University School of Medicine, and Cassandra Gipson-Reichardt, associate professor in the department of pharmacology nutritional sciences at the University of Kentucky, are the coauthors of a new paper in the journal Neuropsychopharmacology about the importance of integrating public health and translational science to address the challenges of xylazine adulteration of fentanyl.  Read the full study here: https://www.nature.com/articles/s41386-023-01680-7 Hosted on Acast.

    The why, when, where, how, and so what of so-called rapidly acting antidepressants

    Sanjay Mathew is a professor and vice chair for research at Baylor College of Medicine and director of the Mood and Anxiety Disorders Program. He’s one of the two authors of a recent review paper in the journal Neuropsychopharmacology, “The why, when, where, how, and so what of so-called rapidly acting antidepressants.” With his colleague Alan Schatzberg, professor of psychiatry and behavioral sciences and director of the Mood Disorders Center at Stanford University, they explore both the drugs that have been studied as rapidly-acting anti-depressants to date, and they also review the challenges and opportunities in how such research is conducted. They say that a version of ketamine has changed the field. Read the full study here: https://www.nature.com/articles/s41386-023-01647-8 Hosted on Acast. See acast.com/privacy for more information.

    AI-based analysis of social media language predicts addiction treatment dropout at 90 days

    In-person treatment for substance use disorders is an incredibly important tool, but there’s a high failure rate — more than 50 percent of people who enter drop out within the first month. There hasn’t been a highly accurate method of identifying who might leave and who might succeed, and knowing this could help centers allocate resources to give the right type of assistance to the right people at the right time. One tool available is called the Addiction Severity Index, which is used to help identify the severity of the addiction and thus customize treatment, but it wasn’t developed to gauge whether a patient might drop out entirely. So a team of researchers decided to mine something known as a digital phenotype.  Dr. Brenda Curtis is a clinical researcher at the National Institute on Drug Abuse Intramural Research Program, and she’s one of the paper’s authors.
