Misuse of Psychiatric Meds Common in Teens

On By ModernMedia

A study into the use and misuse of psychoacttive drugs by US teens has found that about a fifth report misusing their prescribed medications.

Israel Agaku, PhD, of Harvard School of Dental Medicine in Boston, and colleagues used data from a survey of adolescents aged 12-17 prescribed opioids, stimulants, tranquilizers, or sedatives, and found that 20.9% reported using them not as prescribed or directed. There has been considerable concern in recent years over whether adolescents in the United States were being overprescribed psychiatric medication, although a 2018 study concluded that they are not. However, as with adults, the prospect of misuse, possibly leading to substance use disorders is a concern.
Of these youths, 3.4% reported having substance misuse disorders, and this proportion increased to nearly half when youths were taking two or more prescribed medications.

Some 25% of 12-17 year olds reported receiving a psychiatric prescription in the past year. The most common psychoactive prescription in the past year was opioids in 19% of all youth, followed by stimulants (7.2%), tranquilisers (4.3%), and sedatives (2.2%). Tranquilisers were the most commonly misused (40.1%), with substance use disorder in 7%. Stimulants were misused by 24.2%, 3% having a substance use disorder.
Among adults aged 18-25, 41% had been prescribed and had used psychoactive medication, with a third saying they had used opioids in the past year, Similarly to the 12-17 age group, stimulants and tranquilisers were most likely to be misused. 

“The largely overlapping population profiles for medical use versus misuse indicates the high abuse liability of these prescription substances,” the researchers noted. “Having serious psychological distress was consistently associated with misuse of every assessed psychoactive prescription medication.”

The researchers suggested that an open-minded, collaborative approach by healthcare providers was the best approach to dealing with the situation.

“Rather than asking only about cigarette smoking, pediatric practitioners should screen for different commonly used substances, including ‘social use.’ Specifically asking youth and young adults if they have used certain substances, including occasional use, is important as those who use such substances infrequently or only occasionally may not self-identify as users if asked in generic terms,” the researchers explained.

Opioid Deaths Drop when Cannabis Stores are Near

On By ModernMedia

A new US study suggests that opioid-related mortality rates fall in counties where there are legal cannabis stores.

Cannabis was first legalised for medical use in the US in 1996; recreational legalisation began in 2012 with a number of states following suit. Previous research on the effect of legal access to cannabis on opioid overdose mortality had produced conflicting results, with a 2014 study showing a slow increase in deaths, but a subsequent study showing that it reversed over time.

Data on opioid mortality for adults 21 and over was drawn from 2014-2018 CDC data, and a website called Weedmaps for cannabis dispensary details in the 23 states plus the District of Columbia where cannabis dispensaries were allowed to operate as of 2017.

The number of cannabis dispensaries in a county was negatively related to log-transformed age-adjusted opioid mortality rate (β -0.17, 95% CI -0.23 to -0.11). An increase in the number of storefront dispensaries from one to two was linked to a 17% reduction in death rates of all opioid types, and an increase from two to three stores was associated with a further 8.5% drop in mortality.

Eight states plus the District of Columbia allowed recreational storefronts and 15 allowed only medical dispensaries. An increase in medical dispensaries from one to two resulted in a 15% drop in mortality rate; an increase in recreational dispensaries from one to two led to an 11% drop.

Co-author Balázs Kovács, PhD, of Yale University School of Management, said: “We find this relationship holds for both medical dispensaries, which serve only patients who have a state-approved medical card or doctor’s recommendation, as well as for recreational dispensaries, which sell to adults 21 years and older.”

An accompanying editorial pointed out that the relationship was not clear, noting that were was no evidence of substitution. Additionally, individual experiences of benefits and harms could not be inferred.

Although findings are suggestive of a possible link between the increased prevalence of cannabis dispensaries and reduced opioid-related mortality, they do not show causality, Kovács emphasised. “While we find a particularly strong association between the prevalence of storefront dispensaries and fentanyl-related opioid deaths, it is not clear whether cannabis use and fentanyl mortality rates are more specifically linked, or if the strength of the association is due to the rise in fentanyl use and mortality rates during the study period,” he said. 
He added that the potential harms of cannabis, including cognitive development of adolescents, schizophrenia and other medical conditions, and public safety risks, should not be ignored.

New Study Challenges the Need for Some Post-surgical Opioids

On By ModernMedia

Doctors must carefully weigh the pain relief value of opioids for patients against their potential for misuse and inducing opioid addiction even in patients with no history of substance abuse. Now, a new study challenges current practice by showing the effectiveness of an approach that takes a middle way to giving opioids.

Some 16 million people around the world suffer from opioid use disorder, which can result from opioid administration from surgery and for chronic pain. Opioids are highly addictive, with tolerance reached in days and addiction can occur within a matter of weeks, so there is every incentive to minimise exposure of patients to these effective but potentially dangerous medications.

To investigate the effectiveness of minimising opioid use, a team from Michigan Medicine at the University of Michigan conducted a study with 620 patients who had surgery in hospitals across Michigan, had their anaesthetic usage tracked, and filled in surveys within one to three months following their surgeries. The patients were split equally into two groups.
The first group received pre-surgery counseling emphasising non-opioid pain treatment as their first option. Some patients in this group received small, “just in case” prescriptions, but a third of them didn’t receive any opioid prescription at all after surgery.

The patients in the other group received standard care, that is, receiving the usual amount of opioids prescribed after such operations. The prescriptions received in fact were larger than in the opioid sparing group. Most patients didn’t take all of the pills, which if left lying around could be used inappropriately.

Patients in the two groups had the same surgery: either gallbladder removal, full or partial thyroid removal or hernia repair. However, both groups reported equal levels of quality of life and satisfaction with care when followed-up. Most surprisingly, the opioid-sparing group reported less pain overall.

First author Maia Anderson, MD, a resident in the U-M Department of Surgery, said: “It’s so exciting to think about the potential for opioid sparing postoperative pathways to not only reduce the risk of opioids for our patients, but also to substantially decrease the risk of opioid diversion into our communities.”

Senior author Ryan Howard, MD, Surgical Resident, Michigan Medicine commented: “We know that opioids pose serious risks to patients after surgery. We can protect patients from those risks by reducing or eliminating opioids after surgery. But that idea always raises the concern that patients will have uncontrolled pain and feel miserable. This study suggests that’s not the case – patients who get small opioid prescriptions, or even no prescription, are just as satisfied with their recovery after surgery.”

Alcohol Linked to A High Proportion of Cancers

On By ModernMedia

A new study shows that cancer is attributable to a significant proportion of cancer cases across the United States.

It is well known that alcohol is linked to cancers, but the state-level data shows for first time the impact of different levels of alcohol consumption and its cancer effects. This is also concerning for South Africa as the country has high rates of alcohol use, consuming 5 billion litres of alcohol annually, around 9 to 10 litres of pure alcohol for each individual (and likely more if sorghum beer is counted).

From data spanning 2013 to 2016, the percentage of cancer cases that are linked to alcohol ranged from a high of 6.7% in Delaware to a low of 2.9% in Utah. Following this pattern, Delaware also had the highest proportion of alcohol-related cancer deaths (4.5%) and Utah had the lowest (1.9%).
Farhad Islami, MD, PhD, and a team at the American Cancer Society, said: “This information is important for prioritising state-level cancer prevention and control efforts to reduce alcohol consumption and the burden of alcohol-related cancers.”

Alcohol use was more tightly linked to certain cancers: the proportion of oral cavity/pharyngeal cancer cases attributable to alcohol ranged from 36% in Utah to 62.5% in Delaware and was over 45% in all but five US states.

The majority of cases and deaths from the examined cancer types were found more in men, reflecting men’s higher consumption of alcohol.

Overall, alcohol was attributable to 8% of all cancer cases and 3.2% of cancer deaths. The American Cancer Society’s guideline for Diet and Physical Activity for Cancer Prevention states that it is best to abstain from alcohol entirely, and if not to limit drinks to 2 per day for men and 1 per day for women.

Withdrawal Symptoms of Discontinuing Medical Cannabis

On By ModernMedia

A new study on the long terms effects of having used medical cannabis show that over half of people who used it experience withdrawal symptoms between use. And about one in ten experienced worsening alterations in sleep, mood, mental state, energy and appetite over two years.

Patients who use cannabis usually turn to it because of the failure of other pain medications, or to avoid the long-term risks of opioid use. However, the perception that it is “harmless” is incorrect, as it has cannabinoids that act on receptors in the brain, and from which the brain can experience withdrawal symptoms. This can even lead to cannabis use disorder.

Addiction psychologist Lara Coughlin, PhD, who led the analysis said, “Some people report experiencing significant benefits from medical cannabis, but our findings suggest a real need to increase awareness about the signs of withdrawal symptoms developing to decrease the potential downsides of cannabis use, especially among those who experience severe or worsening symptoms over time.”

After they had gone a significant time without cannabis, the 527 participants in the study were asked whether they had any one of 15 symptoms, ranging from irritability to nausea. Using an analytic method, they empirically grouped them into three groups ranging from mild or moderate symptoms to severe, with most of the symptoms. They then surveyed the patients again after one year and then again after two years. Those in the mild class showed the most stability in symptoms over time.

Younger participants were more likely to be in the severe group, and were more likely to have a worsening trajectory. Coughlin concluded that patients seeking cannabis use for pain need to discuss it with their health care providers, and seek psychosocial treatments such as cognitive behavioural therapy.

Nearly a Fifth of Cancer Patients on Opioids Misuse Them

On By ModernMedia

A new report reveals that 19% of cancer patients receiving opioids are misusing them, referred to a nonmedical opioid use (NMOU) behaviour. 

Opioid addiction remains a persistent and serious problem in the United States, and is growing elsewhere in the world, with some 16 million individuals worldwide suffering from opioid misuse disorder.
The study,  led by Sriram Yennurajalingam, MD, MS, of MD Anderson Cancer Center in Houston, included 1554 patients at a supportive care clinic for a comprehensive cancer centre. Of those engaging in NMOU behaviour, the most common (29%) was an early request for a refill, followed by self-directed dose escalation (15%), co-using illicit or non-prescribed drugs (13%), and impaired daily function due to opioids (11%).

Independent risk factors that increased the risk of NMOU behaviour included being single or divorced, as well as pain levels, opioid risk screening score, and morphine equivalent daily dose.

In their recommendations, Yennurajalingam and co-authors wrote: “Based on these findings, a universal screening, setting limits on opioid use by limiting supply, more intense follow-up with an interdisciplinary team to provide optimal use of medications for pain and symptom management, and the provision of counseling and support to patients and their family members may help prevent the development of these NMOU behaviors.”

Opioid Use Linked to Pancreatic Cancer Risk

On By ModernMedia

New research has shown that the use and misuse of the highly addictive opioid class of medications may pose an additional threat – pancreatic cancer. 

In the United States, opioid misuse has spiralled into one of the biggest healthcare epidemics facing the country. Of 70 000 deaths from substance abuse in the country in 2017, 68% involved opioids. Among patients prescribed opioids for chronic pain, 29% are misusing them and 12% have developed an opioid misuse disorder. Rates of pancreatic cancer are also on the increase in the US. In West Central Asia, opium use recently been linked to pancreatic cancer.Using Centres for Disease Control (CDC) data, the study’s researchers controlled for confounding variables, took opioid death rates as a surrogate for proscription and misuse, and compared it to incidences of pancreatic cancer. 

Analysing the dataset, they found that opioid use was associated with pancreatic cancer rates, with the opioid use rates predicting the pancreatic cancer trends years later.Faraz Bishehsari, MD, Ph.D., the corresponding author of the study, said: “Our mechanistic studies could provide further insights on the pathways that opioid could potentially impact progression of cancer.”

In order to confirm the findings, there is a need for sizeable population-based studies or longitudinal datasets that reliably track long-term outcomes in opioid users. Once these findings are confirmed by population-based studies, these will have an impact in considering alternative pain management methods in patients.Adding credence to this link is a recent post-hoc analysis of advanced cancer patients that showed patients receiving regular opioid antagonists had a significantly improved survival rate over placebo.

Unmedicated Autism Associated With Substance Abuse

On By ModernMedia

A Taiwanese study has shown that individuals diagnosed with untreated autism spectrum disorder (ASD) have higher rates of substance abuse compared to those on treatment.

The researchers used inpatient and outpatient data of 6 599 individuals with ASD who had at least 3 outpatients visits for ASD, drawn from the Taiwan National Health Insurance Research Database. They found an increased risk of substance use disorder (SUD) among those who were not receiving medication for ASD (adjusted hazard ratio 2.33, 95% CI 1.89-2.87). The risk for drug abuse was three times higher, and the risk for alcohol abuse was two times higher.

Additionally, those with comorbid SUD had over a three times greater risk of death over a follow-up period of 8.1 years.Those taking psychotropic agents had a 40% reduction for SUD risk when taking one agent, and a 63% reduction with a multiagent.

There were several comorbidities of psychiatric disorders seen in patients with ASD, such as intellectual disability, attention deficit hyperactivity disorder, tic disorder, epilepsy, obsessive-compulsive disorder, mood disorder, anxiety disorder, and impulse control disorder. However, individuals with ASD had a higher risk of SUD even compared with matched controls with the same comorbidities. SUD risk was highest with certain comorbidities; untreated ASD with comorbid tic disorder was 6 times higher; with a comorbid impulse control disorder, it was five times higher.

The researchers stated that these are critical findings, but of limited use due to the “umbrella term” of substance use disorder, and further studies will be needed to examine the specific types of drug use amongst individuals with ASD. Future research could investigate whether non-pharmaceutical treatments such as behavioural therapy had the same effect.They conclude that screening  individuals with ASD for SUD is important, given the findings of the study.

Ask Patients about Any Cannabis Use Frankly

On By ModernMedia

With legalisation and increasingly widespread use of cannabis, healthcare providers should be as open-minded about cannabis use in their patients as possible

Marian Wilson, registered nurse and associate professor at the Washington State University College of Nursing, argues in a recent paper that enquiring about it like they would alcohol or tobacco is necessary to obtain adequate patient histories and build trust.

Many studies have indicated that patients are using it to treat pain in much the same way they do opioids. Since they are using it in this way, they need to be asked about it for pain management. Since patients are reluctant to disclose this information with clinicians, there is currently a lack of information on prevalence and usage habits.

“We want this paper to guide providers in how they can start opening up this conversation and normalising it,” Wilson said. “Central to patient-centred conversations is understanding the top priorities of patients. Researchers have suggested that clinicians should ask ‘What matters to you?’ as well as ‘What is the matter?'”

Il-10 Found to be Involved in Alcoholism

On By ModernMedia

Researchers have discovered that the anti-inflammatory IL-10 plays a direct role in alcoholism. Neurological research into addiction and alcohol has focused on the amygdala, which plays a key role in drives, emotions and behaviours.

Alcoholism is a growing problem in need of effective treatment. Interleukin 10 (IL-10) is an immune protein that has strong anti-inflammatory properties and is known to protect the brain from inflammation resulting from disease or injury.

In the brains of mice which chronically used alcohol, the amount of IL-10 was lowered in the amygdala and did not correctly signal neurons, and so was partly responsible for alcohol consumption behaviours. This was despite the overall higher level of IL-10 throughout the brains of chronic alcohol using mice.

“We found that chronic alcohol exposure compromises brain immune cells, which are important for maintaining healthy neurons,” said first author of the study Reesha Patel, PhD. “The resulting damage fuels anxiety and alcohol drinking that may lead to alcohol use disorder.”

The researchers counteracted the decrease of IL-10 amounts and signalling in mice, and the mice’s excessive alcohol use declined, and a decrease in anxiety was also noted.

Marisa Roberto, PhD, a professor in Scripps Research’s Department of Molecular Medicine, led the research. She said, “We’ve shown that inflammatory immune responses in the brain are very much at play in the development and maintenance of alcohol use disorder. But perhaps more importantly, we provided a new framework for therapeutic intervention, pointing to anti-inflammatory mechanisms.”
