Study Reveals Sources of Opioid Poisoning Among Children

Original post: Newswise - Substance Abuse Study Reveals Sources of Opioid Poisoning Among Children

A dog’s pain medication, a grandparent’s pill organizer, even a discarded tissue: Rutgers Health research reveals they’re all potential sources of opioid poisoning for young children.

Researchers at the New Jersey Poison Control Center examined 230 cases of opioid exposure in children ages 1 month to 6 years over a five-year period. Their findings in the Journal of Pediatrics show how children access these dangerous drugs.

“We’re seeing this in our clinical practice,” said Diane Calello, the medical director of the poison control center and senior author of the study. “I’ve seen too many kids in my practice at University Hospital who have gotten severely poisoned because they got opioids in their house.”

An overwhelming majority of exposures (97 percent) were unintentional. More than 91 percent occurred in the child’s home, and 84.3 percent resulted in the child being admitted to a health care facility.

While many cases involved a child accessing a parent’s medication, the study uncovered several unexpected sources of exposure. Grandparents’ medications were implicated in 17.4 percent of cases, highlighting what the researchers described as an often-overlooked risk factor: exposure to older adults who may not be as vigilant as parents about securing their medications.

Another significant risk came from pet medications, which were involved in 4.3 percent of cases. Children sometimes accessed these opioids directly and sometimes accessed pet medication that had been mixed with food, such as peanut butter, and then left out.

Children ages 2 and under accounted for 80 percent of all exposures. Kids in this age group face particularly high risk because of their exploratory behavior and inability to distinguish between safe and dangerous substances.

The study drew data from reports to the New Jersey Poison Control Center between January 2018 and December 2022. Researchers manually extracted and analyzed information from the center’s database, focusing on single opioid exposures in young children.

While prescription opioid pills were the most common source of danger, the study uncovered other scenarios. Children accessed used fentanyl patches, illicit drug paraphernalia and even opioid residue left on discarded items such as tissue paper and cotton balls.

The study highlights the importance of proper medication storage and disposal, Calello said.

“One opioid pill could actually kill a 2-year-old,” she said. “And yet, a parent who may take that opioid pill every day may not realize that even though it’s very familiar to them, it is deadly.”

The study authors said there is a need for more comprehensive education about the dangers of opioids in the home. Calello suggested it should include grandparents and anyone who might bring medications into a home where children are present.

One potential solution is increasing access for parents and caregivers to naloxone, a medication that can reverse opioid overdoses, Calello said.

“I’ve seen several cases of young children where I thought that if this mom or dad had naloxone with them, they could have given it, and this child may have had a better outcome,” she said.

Looking forward, the study team is preparing to publish data on how children nationwide are exposed to opioids. Those figures show more pediatric exposures to illicit opioids and medications for treating opioid addiction.

Calello added that she hopes to study the effects of distributing naloxone more widely to parents.

“That would be a good next step,” she said. “It could make a big difference.”

Rutgers and New Jersey Partner to Provide Integrated Behavioral Health in Primary Care Practices in Newark and Elizabeth

Newswise — Behavioral health professionals at Rutgers will work with the state to increase and improve the delivery of mental health and substance use services to the underserved communities of Newark and Elizabeth under a $4.5 million federal grant.

The New Jersey Division of Mental Health and Addiction Services has received the funding and will work with the Rutgers University Behavioral Health Care’s Center for Integrated Care (CIC).

The center will assist in a plan to bring more behavioral care providers directly into primary care offices. Those in the industry refer to this particular integrated care system as the  Collaborative Care Model. The idea is to assess the patient and connect him with behavioral health and psychiatry immediately without the need for referrals. The approach would save patients time, increase their access to care, ease the workload of the primary care doctors and save medical costs.

“This is an exciting partnership with the state that allows us to not only improve treatment and treatment access in medically underserved areas, but to also have the opportunity to impact state planning and advance collaborative care across state health programs,” said Holly Lister, a psychologist and program manager for the center.

The project is designed to increase the identification and treatment of people with behavioral health disorders, improve engagement and retention in care and use measurement-based care to improve the treatment of serious mental illness, child and adolescent emotional disturbance and co-occurring physical health conditions – directly in primary care.

This is the fourth grant to assist the CIC in increasing integrated behavioral health services and promote education about integrated care models throughout New Jersey.

The funding will also include educating healthcare providers and the public about the collaborative care approach to providing care.

Patients with Alcohol Use Disorder at Risk of Liver Disease May be Less Commonly Referred for Liver Treatment if they are primarily seen for Mental Health Disorders

Newswise — People with alcohol use disorder (AUD) who are at risk of advanced liver disease are less likely to be referred for liver evaluation and care if they present primarily with alcohol-related mental health issues or a mental health diagnosis, according to a study of referral practices in Virginia’s largest health system. The findings point to the possibility of widespread missed opportunities for treating three conditions that commonly co-occur: AUD, mental health disorders, and liver disease. Recent years have seen notable increases in the USA in alcohol-related deaths, mental health disorders, and hospital admissions relating to alcohol use and concurrent mental health conditions. AUD is a significant cause of liver disease, and both addiction and co-occurring mental illness can be barriers to successful liver treatment. Integrating AUD treatment, mental health care, and hepatology (liver care) is necessary to improve outcomes, but data suggests this approach is not the norm. For the study in Alcohol: Clinical & Experimental Research, investigators evaluated which patients with excessive alcohol use and potentially advanced liver disease were referred to hepatology for evaluation and treatment.

Researchers worked with data representing 316 patients experiencing excessive alcohol use who were treated between 2013 and 2023. All the patients in the study had results from FIB-4—a blood test included in routine lab work—correlating to a high risk of advanced liver fibrosis. The researchers collected information on the participants’ demographics, alcohol-related hospital admissions, predicted mortality, referral patterns, and mental health diagnoses and hospitalizations. They used statistical analysis to explore factors associated with referral to hepatology.

Most patients were men, and the average age was 60. Six in 10 were Caucasian, and nearly 4 in 10 African American. Only 37% of patients with excessive alcohol use and a high risk of advanced liver disease were referred for liver care. Referrals to hepatology were associated with higher FIB-4 scores, more co-occurring health conditions, and hospitalization due to AUD-related liver issues or gastrointestinal concerns. Patients less likely to be referred for liver care included those admitted to the hospital for physical injury or alcohol-related mental health concerns, who presented with mental health disorders, or who were older. Of these, patients with depression or suicidal ideation were more frequently referred to hepatology than patients with other mental health diagnoses.

The study identified an opportunity to increase integration of care across specialties serving patients with alcohol-related liver disease and mental health conditions. People presenting with primarily mental health or addiction issues were especially unlikely to be referred for appropriate liver care. The findings highlight the need for healthcare providers to be educated about the importance of multispecialty care, including hepatology and GI referrals. Managing liver disease is necessary for reducing the risk of cirrhosis, cancer, and other conditions and for liver transplant evaluation. Similarly, early identification of AUD in patients with liver disease is essential for improving outcomes.

Referral to hepatology is lower in patients with excessive alcohol use who have mental health disorders despite a high FIB-4 index. K. Houston, S. Harris, A.Teklezghi, S. Silvey, A. D. Snyder, A. J. Arias, J. S. Bajaj.

Ultra-Low-Dose Ketamine Can Curb Opioid Withdrawal

Newswise — Drug overdose is the leading cause of injury deaths in young adults in the United States, with fentanyl causing over 70,000 deaths annually.

Many people who use fentanyl become trapped in their addiction out of fear and a low tolerance for the withdrawal symptoms, which include muscle cramps, nausea, chills, sweats and intense cravings. 

They can’t stop using fentanyl, and they also have trouble starting either of the two medications, methadone and buprenorphine, that can dramatically reduce their risk of overdose death.

Research findings published Aug. 29 in Addiction Science & Clinical Practice may offer hope. A pilot study showed that a small amount of ketamine can reduce or eliminate the withdrawal symptoms associated with quitting fentanyl.

“The main takeaway is that we have found an easier way for people trapped in the grip of fentanyl addiction to get started in treatment,” said Dr. Lucinda Grande, a clinical assistant professor of family medicine at the University of Washington School of Medicine. She was the study’s lead author. 

“Methadone can be difficult to access due to strict federal regulations, and starting buprenorphine can cause severe withdrawal symptoms before those who start it become stabilized,” added study co-author Dr. Tom Hutch. He is the medical director of the opioid treatment program at We Care Daily Clinics in Auburn, Wash. “Ketamine, at an imperceptibly low dose, helps bridge that gap.” 

Over 14 months, Grande and colleagues in Auburn and Olympia prescribed ketamine to 37 fentanyl-addicted patients whose fear of withdrawal symptoms had deterred them from trying buprenorphine. Twenty-four patients actually tried the drug, and 16 completed the transition to buprenorphine. 

Most patients reported a reduction or elimination of withdrawal symptoms after each ketamine dose, the effect of which lasted for hours. Of the last 12 who completed the transition, 92% remained in treatment for at least 30 days.

Patients placed a ketamine lozenge or syrup under the tongue. The 16 mg dose is a small fraction of that typically used for anesthesia, the main clinical role of ketamine for 50 years, according to Grande. That dosage also is less than half of the smallest ketamine dose prescribed for depression treatment, an increasingly common use of this medication.

Researchers monitored patients daily or almost daily, and refined the treatment strategy based on patient response and prescriber experience.

Grande developed the concept after she learned that emergency-medicine physician and coauthor Dr. Andrew Herring of Oakland, California, used a higher, sedating dose of ketamine successfully in his emergency department to resolve a patient’s severe case of withdrawal from fentanyl addiction. 

Grande is a primary-care and addiction doctor in practice near Olympia who, in the past dozen years, has used low-dose ketamine to treat more than 600 patients for chronic pain and depression. 

Ketamine has gained prominence in the news since actor Matthew Perry of the sitcom “Friends” overdosed on the drug and drowned. Perry had undergone high-dose ketamine treatment for depression, news reports have suggested.

“Our study underscores the enormous potential of this medication for addressing important health problems such as depression, chronic pain and now fentanyl-use disorder,” said Grande. Ketamine’s positive attributes have been overshadowed by Perry’s death, she said.

Grande hopes this pilot study’s results will be confirmed by larger studies. “I am excited about these results,” she said. “This is a wonderful opportunity to save lives.”

Cannabis and older adults: Poll shows current use patterns, beliefs and risks

Original post: Newswise - Substance Abuse Cannabis and older adults: Poll shows current use patterns, beliefs and risks

Newswise — Whether they’re using it for recreational or medical reasons, a sizable percentage of people in their 50s and older have smoked, eaten, drunk or applied to their skin at least one form of cannabis in the past year, a new poll shows.

In all, 21% of people age 50 and older said they used a form of cannabis that contains the psychoactive compound THC at least once in the past year, according to new findings from the University of Michigan National Poll on Healthy Aging. The poll report focuses on use of cannabis products with psychoactive amounts of THC, not CBD-only products.

More than half of those who used a cannabis product did so frequently: 12% of adults aged 50 and older said they did so at least once a month. Those aged 50 to 64, and those who are in fair or poor physical health, or in lower income households were more likely to report using cannabis at least monthly. 

As for the reasons older adults use cannabis, many cited sleep (68%), help with pain (63%) or mental health (53%), and/or to relax or feel good (81%).

The poll also reveals potential risky behaviors related to cannabis use. 

Among those who use cannabis at least once a year, 20% said they had driven a vehicle within two hours of consumption; many experts recommend waiting two or even three times that long. And the rate of such driving was even higher – 27% – among those who use cannabis at least once a month. 

In addition, nearly half of older adults who use cannabis products at least monthly had not discussed their use with their health care provider. And more than 20% reported at least one sign of potential dependence on cannabis.

The poll is based at the U-M Institute for Healthcare Policy and Innovation, and supported by AARP and Michigan Medicine, U-M’s academic medical center. 

Erin E. Bonar, Ph.D., a U-M addiction psychologist who worked with the poll team on the report, says the findings suggest a need for action at the policy, clinical and community levels to identify those who may need treatment for cannabis addiction and to discourage driving or other risky behaviors after consumption. 

“With some form of cannabis use now legalized in 38 states and on the ballot this November in several others, and the federal rescheduling process under way, cannabis use is likely to grow,” she said. “But as this poll shows, it is not risk-free, and more attention is needed to identify and reduce those risks.”

Bonar is a member of IHPI, the U-M Addiction Center and the U-M Injury Prevention Center as well as a professor in the Medical School Department of Psychiatry

In addition to the national poll report, the team compiled data for Michigan adults age 50 and older compared with those in other states; a summary is available at https://michmed.org/JYJer and an interactive data visualization is available at https://michmed.org/4e2KW. 

Cannabis potency and addiction: Views of all older adults

The poll team also asked all older adults – including those who don’t use cannabis – about their views of cannabis. The results suggest a need for more public awareness efforts, Bonar says. 

People in their 50s and beyond may have familiarity with cannabis from decades ago, whether through direct use or indirect knowledge during a time when it was illegal for any use in all states. Because of this, the poll team asked whether they believe cannabis is stronger today than it was 20 to 30 years ago.

The vast majority – 79% — of older adults said they thought this was true. But Bonar notes that this means 21% aren’t currently aware of the major increases in THC levels found in cannabis available today, compared with levels in the 1990s and before. 

Meanwhile, 72% of all older adults said they believe people can become addicted to cannabis. But, Bonar notes, this means more than a quarter of older adults aren’t currently aware that research has shown conclusively that cannabis addiction is real and can affect someone’s life and health just as addiction to other substances can. 

Importance of discussing with health care providers 

For those who use cannabis, especially those who use it often, poll director Jeffrey Kullgren, M.D., M.P.H., M.S. says the poll findings show the importance of communicating with their health care provider about their use. 

In all, 56% of those who use cannabis with THC at least monthly said they had spoken with their regular health care provider about their use. Most of them said they had brought the topic up. 

Talking openly with a provider about use could help identify risky drug interactions, and spot those experiencing signs of cannabis dependence or addiction. 

In all, 22% of those who use cannabis at least monthly said in the past year they had had to use more cannabis to feel the effect they wanted, and 21% said using the same amount of cannabis had less of an effect on them than it had before, while 17% said they had increased the amount or frequency of their cannabis use. Another sign of potential addiction – strong desires or cravings to use cannabis with THC – was reported by 13% of those who use cannabis at least monthly.

“Even if your doctor, nurse practitioner or pharmacist doesn’t ask if you’re using cannabis products, it’s important to offer this information, no matter whether you’re using it to address a physical or mental health concern, or simply for pleasure,” says Kullgren, a primary care physician at the VA Ann Arbor Healthcare System and associate professor of internal medicine at U-M. “Many prescription medications and over-the-counter drugs, as well as alcohol, can interact with cannabis and cause unexpected or unwanted effects. And there are only a few conditions where we have good evidence of a medical benefit from cannabis, though this could change with time.”

The current process at the federal level to change how cannabis is listed on the schedule of controlled substances may free more researchers to do studies of cannabis-derived products in clinical trials involving human volunteers. Right now, such research is very limited because of federal restrictions. 

The poll report is based on findings from a nationally representative survey conducted by NORC at the University of Chicago for IHPI and administered online and via phone in February and March 2024 among 3,379 adults ages 50 and older. The sample was subsequently weighted to reflect the U.S. and Michigan populations. Read past National Poll on Healthy Aging reports and about the poll methodology.

Virtual learning detrimental to school attendance, especially in districts with higher poverty rates, study finds

BYLINE: Tracy DeStazio

Newswise — Since the COVID-19 pandemic, rates of chronic absenteeism have nearly doubled across the nation for students in kindergarten through grade 12.

This increase was tied to the mode of instruction during the early years of the pandemic. In particular, schools that employed virtual learning as the primary teaching mode during the 2020-21 school year experienced a greater increase in chronic absenteeism in the following year. That increase was significantly greater in school districts with higher levels of poverty, according to new research from the University of Notre Dame.

William Evans, the Keough-Hesburgh Professor of Economics and co-founder of Notre Dame’s Wilson Sheehan Lab for Economic Opportunities, co-authored the study with current undergraduate student Kathryn Muchnick and 2024 graduate Olivia Rosenlund. Their work was recently published in the scientific journal JAMA Network Open.

The study analyzed data for two years from more than 11,000 school districts across the United States and found that chronic absenteeism rates increased from 16 percent in 2018-19 to nearly 30 percent in the 2021-22 school year. Students whose schools had full virtual instruction during the pandemic had chronic absenteeism rates that were nearly 7 percentage points higher than those schools that were fully in person, according to the research.

A student is considered chronically absent if he or she misses at least 10 percent of the instructional days in any given school year. That equates to more than three weeks of absences during a 180-day academic year.

As reported in the study, chronic absenteeism has been shown to lead to lower test scores, reduced social and educational interactions, lower rates of high school graduation and increased substance use. The increase in chronic absenteeism began to occur as public schools in the U.S. were attempting to return to pre-pandemic modes of in-person teaching.

Previous studies have indicated that moving away from in-person instruction during the 2020-21 school year to online teaching methods reduced student achievement and educational development, adversely affected children’s mental well-being and decreased school enrollment.

“We’ve learned a lot from the pandemic,” Evans said, “and a lot of work has gone into researching what effects virtual learning has had on students. It’s really difficult when you disrupt their educational experience by going remote.”

Both of Evans’ co-authors were high school students during the pandemic, giving them a uniquely personal perspective on the study’s results. Rosenlund said that when she entered the end of her senior year with fully virtual classes, she and her classmates “definitely had lower motivation to learn during that time compared to when class was fully in person.”

Muchnick added, “The shift in student motivation after online learning [back to in-person] was palpable.”

The research also indicated that chronic absenteeism rates hit at-risk students and school districts with the highest levels of poverty the hardest. Those school districts saw chronic absenteeism soar more than 10 percentage points higher among students who had participated in fully remote instruction, versus in-person learning.

“There is growing evidence that those in the most precarious situations were the ones that were really hurt the most by virtual instruction,” Evans said. “The districts with higher levels of poverty had higher rates of chronic absenteeism already, and they were much more aggressive at using virtual learning during COVID. So you took a vulnerable population, used this method of delivery for educational instruction, and the outcomes for these children are substantially worse.”

Households with lower incomes or fewer resources were less likely to have reliable or high-speed internet service and had far less access to quality computers or technology, making for a less-than-ideal virtual learning environment. “It was pretty detrimental for those kids who were most at risk in the first place,” Evans added, “and now they’ve been pushed further behind as a result of these policies.”

Although the study did not specifically explore the reasons behind the drop in school attendance, it did offer several possible explanations. First, roughly 10 to 20 percent of students were experiencing post-COVID-19 symptoms and may have elected not to go to school for medical and health reasons. Second, there was a corresponding increase in teacher absences and substitute teacher shortages that made students less compelled to go to school. Third, a greater occurrence of mental health issues, which is often coupled with an increased preoccupation with social media, may have kept students at home. Finally, following the pandemic, parents appear to be more willing to allow their children to miss school for a variety of reasons.

With the worst of the pandemic behind us, many parents, school teachers and administrators believe that virtual instruction is here to stay and will continue as a major component of K-12 education, potentially being used as a substitute for in-person teaching under certain circumstances, such as snow days.

“It’s going to be really difficult to put the genie back in the bottle in this context,” Evans said.

Finding a balance of how to use virtual learning in a way that does not negatively impact the students’ overall educational experience will be crucial, according to the researchers.

Rosenlund added, “It’s disheartening that students are still suffering from the negative effects of online learning. I hope that we can consider its implications more carefully going forward.”

The researchers suggest that educators and policymakers examine the evidence when establishing policies and practices related to online learning, particularly for those communities supporting at-risk students, in order to achieve equitable outcomes for all students.

“I think we need to take a more holistic approach in thinking about how to deal with these pandemics in the future,” Evans said.

Sleep-deprived, cyberbullied teenagers addicted to smartphones now a common global phenomenon

Newswise — Combine cyberbullying, smartphone use, lack of sleep and poor mental health, and you have the perfect storm for a teenage meltdown.

Australian researchers have polled more than 50,000 primary and secondary school students aged 7-19 years about the link between their sleep and nighttime phone habits, experience of cyberbullying and stress levels.

Researchers from the Behaviour-Brain-Body Research Centre at the University of South Australia found that across all genders and age groups, phone use overnight not only robbed children of sleep, but it also had a negative impact on their mental health, especially among those who had been cyberbullied.

Whether one habit causes or stems from another is not crystal clear, but the study findings should send a clear signal to parents about the need to manage digital device use at home.

Approximately 66% of teenage girls and 58% of teenage boys (aged 12-19 years) reported being cyberbullied at least once in the preceding school term. Among the girls, 17% said they slept less than eight hours a night and the corresponding figure for the teenage boys was 13%.

Stress levels in the moderate-to-severe range were reported by 38% of teenage girls and 23% of teenage boys.

While cyberbullying and lack of sleep were not as common in primary aged children (7-11 years), one in five reported moderate-to-severe stress.

For the purposes of the study, “nighttime” refers to phone use when children are supposed to be sleeping, not prior to bed.

UniSA researcher and co-author Dr Stephanie Centofanti says that girls are particularly vulnerable because their smartphone use at night is higher than other age groups and they start using social media at a younger age.

“We found that frequency of nighttime phone use and getting less than eight hours sleep a night not only peaked in early adolescence but was also more evident in young girls,” Dr Centofanti says.

“Pre-teens are at higher risk for socio-emotional disorders because they are at a developmental stage where they are less prepared cognitively, behaviourally and neurobiologically.”

The researchers say that outside of the digital environment, boys are more likely to be physically bullied, while girls normally resort to psychological or relational bullying, which is more easily enabled online.

Approximately 15% of children in the study reported being cyberbullied, with a higher frequency of boys in primary school and girls in secondary school.

More than one third of primary school children and over 60% of teenagers in the study reported using their phone at night when they were supposed to be sleeping.

Of the children who experienced cyberbullying, almost 75% admitted they checked their phone throughout the night, compared to less than half for those who had never been cyberbullied.

“It is clear that parents need to pay closer attention to managing smartphone use at night, particularly if their children are more vulnerable to cyberbullying, and to ensure their children get enough sleep,” Dr Centofanti says.

The findings are published in the journal Adolescents.

Physical health has its yardsticks. Mental health is still searching for the right ruler

Original post: Newswise - Substance Abuse Physical health has its yardsticks. Mental health is still searching for the right ruler

Newswise — While doctors can track cancer progression at the cellular level or use a blood test to obtain precise blood cholesterol levels, talk therapy’s impact on mental health is still largely reliant on gut feelings more than hard data. 

A national initiative led by the National Institute of Mental Health is now underway to find figurative “rulers” that can accurately measure and compare the quality of the various mental health treatments available. To lead off this effort, UCLA Health researchers were awarded a four-year, $2.1 million federal grant to study and test whether such a quality measure can be created and applied across all social groups in the United States. 

“We have so many problems with mental health in this country that are only getting worse,” said Dr. Alexander Young, professor at UCLA Health’s Department of Psychiatry and Biobehavioral Sciences. “We really need to be able to provide access to high quality care for all the diverse populations that we serve.” 

Demand for mental health care in America has soared in recent years, with a majority of psychologists reporting having waiting lists for new patients, according to a recent survey by the American Psychological Association. Meanwhile, more treatment options are available including numerous evidence-based psychotherapies, neuromodulation including Transcranial Magnetic Stimulation, new medications and telehealth services among others.  

While some larger health care providers have made efforts to address the issue, the effectiveness and quality of these treatments have generally not been accurately monitored at a national level, resulting in a scarcity of clinical data on patient outcomes, Young said.  

As a result, governmental organizations, provider organizations, insurance companies, patients and families have little information to gauge the quality of the mental health services they are supporting or receiving, Young said. 

As part of a national initiative, UCLA researchers will aim to create accurate quality measurement based on routine, regular patient reports of their symptoms. To develop and test this, Young and his colleagues will utilize a unique database of more than 5 million symptom assessments from 500,000 patients collected during mental health treatment. The data are being analyzed in conjunction with the ACORN Collaboration, an international consortium that includes mental health and substance abuse treatment centers.  

One important aspect of the project will work to ensure that the quality measure supports improvement in socioeconomic disparities in both the access to and quality of mental health treatment. 

“We need to come up with a measurement that’s consistent across social groups and accurate given the diversity of people and situations in the United States,” Young said. 

Other collaborators in the study from UCLA include Li Cai, Nick Jackson, April Thames and Lucinda Leung. 

Three Concepts Key to Recovery from Substance Use Disorders Identified Via Reviewing 30+ Years of Scientific Findings

Newswise — Certain concepts have a demonstrated basis for aiding recovery from dangerous alcohol or substance use, according to an analysis of scientific literature since 1990. Self-efficacy (a belief in one’s ability to achieve a goal), social support, and managing cravings are among the treatment elements best supported by evidence. Effective treatment for alcohol use disorder (AUD) and other substance use disorders (SUDs) depends on understanding how human behaviors change and incorporating that knowledge into clinical practice. An ongoing research effort continues to investigate varying treatment approaches and how they relate to recovery outcomes, but those findings have not been well synthesized into a useful format. For the new review published in Alcohol: Clinical & Experimental Research, researchers from around the USA reviewed published studies, identified the treatment elements best supported by data, and evaluated their potential as key factors in behavior change. The researchers drew on existing study design criteria for validating conclusions about treatment elements.

The researchers explored reviews of studies published between 2008 and 2023 involving AUD and SUD treatments and the effects on substance use and related outcomes in adults. Three constructs involved in treatment were the most well-supported by data from 11 studies: self-efficacy, social support, and craving (coping skills, also well-supported, did not suit the current review process). They then reviewed 48 studies published between 1990 and 2023 that focused on one or more of these three concepts in adults’ recovery, and that met rigorous methodology standards. The 48 studies used varied research designs, participant samples, and contexts.

The analyzed studies provided support for self-efficacy, social support, and craving as factors that likely influence people’s behaviors in treatment or recovery. The researchers called for these three constructs to be incorporated into AUD and SUD treatment and clinical training. Such an approach could improve recovery interventions, inform new treatments and clinical training, help clinicians align patients with approaches likely to work for them, and hone community-based recovery programs.

The researchers called for additional research on how these three concepts drive behavior change and for mining existing science to identify other evidence-based approaches. They recommended several directions for future research. These included expanding the examined outcomes to other manifestations of mental and physical health and experimenting with key elements of treatment to generate direct evidence of associations between those constructs and outcomes. Investigating the roles of context (such as policies, incentives, social norms, and settings) and combinations of influences could improve outcomes across varied real-world situations. Specifying how behavioral change occurs—such as the relevant neurological and biological pathways—is a critical gap that needs to be addressed.

UC Irvine-led team finds that compound in rosemary extract can reduce cocaine sensitivity

Newswise — Irvine, Calif., Aug. 20, 2024 — A team of researchers led by the University of California, Irvine has discovered that an antioxidant found in rosemary extract can reduce volitional intakes of cocaine by moderating the brain’s reward response, offering a new therapeutic target for treating addiction.

The study, recently published online in the journal Neuron, describes team members’ focus on a region of the brain called the globus pallidus externus, which acts as a gatekeeper that regulates how we react to cocaine. They discovered that within the GPe, parvalbumin-positive neurons are crucial in controlling the response to cocaine by changing the activity neurons releasing the pleasure molecule dopamine.

“There are currently no effective therapeutics for dependence on psychostimulants such as cocaine, which, along with opioids, represent a substantial health burden,” said corresponding author Kevin Beier, UC Irvine associate professor of physiology and biophysics. “Our study deepens our understanding of the basic brain mechanisms that increase vulnerability to substance use disorder-related outcomes and provides a foundation for the development of new interventions.”

Findings in mice revealed that globus pallidus externus parvalbumin-positive cells, which indirectly influence the release of dopamine, become more excitable after being exposed to cocaine. This caused a drop in the expression of certain proteins that encode membrane channels that usually help keep the globus pallidus cell activity in check. Researchers found that carnosic acid, an isolate of rosemary extract, selectively binds to the affected channels, providing an avenue to reduce response to the drug in a relatively specific fashion.

“Only a subset of individuals are vulnerable to developing a substance use disorder, but we cannot yet identify who they are. If globus pallidus cell activity can effectively predict response to cocaine, it could be used to measure likely responses and thus serve as a biomarker for the most vulnerable,” Beier said. “Furthermore, it’s possible that carnosic acid could be given to those at high risk to reduce the response to cocaine.”

The next steps in this research include thoroughly assessing negative side effects of carnosic acid and determining the ideal dosage and timing. The team is also interested in testing its efficacy in reducing the desire for other drugs and in developing more potent and targeted variants.

In addition to UC Irvine researchers, scientists from the University of West Virginia and the University of Colorado participated in the study. See the full list here.
