This study is a pragmatic clinical trial examining the comparative effectiveness of two stimulant medications (methylphenidate and amphetamine) in the treatment of ADHD in children and adolescents with autism. Using a sequential, multiple assignment randomization trial (SMART) design the study will not only assess these two medications but also the role of an increasingly popular class of ADHD medication, the alpha-2 agonists. Findings from this study will help improve clinicians' approach to medication selection and reduce the repeated trials of multiple medications that are current standard care.

Do we need urine drug screens in opioid addiction treatment: An observational study on self-report versus urine drug screens

Article

Author: Hudson, Jacqueline ; Thabane, Lehana ; Dennis, Brittany B ; Worster, Andrew ; Samaan, Zainab ; McEvoy, Alannah ; Marsh, David C ; Rodrigues, Myanca

BackgroundThe substance use crisis continues to progress. Medication for Opioid Use Disorder (MOUD) are prescribed to reduce opioid use and related harms; however, many individuals continue to use substances while on treatment. The objective of this study was to describe the temporal and demographic trends of the agreement between self-reported and urine tested substances.MethodsThe current study is a retrospective secondary analysis of three phases of a prospective cohort study (Pilot 2011, Genetics of opioid addiction (GENOA) 2013-2017, and Pharmacogenetics of opioid substitution treatment (POST)) 2018-2022) spanning 2011-2022. We compared the self-reported substance use data for opioids, benzodiazepines, amphetamine/methamphetamine (AMP/MET), and cocaine with urine drug results. We compared the positive predictive value (PPV), false omission rate (FOR), sensitivity, and specificity between (i) different drugs; (ii) by sex, and (iii) age group at enrollment in each phase of the study using self-reported substance use at baseline and retrospective electronic health record data on urine drug screenings collected over the same time period.ResultsOverall, the average PPV and FOR for any drug across all phases was 80.7 % and 37.9 %, respectively. Sensitivity and specificity were highest for cocaine and lowest for benzodiazepines. We found no specific trend by sex. Lastly, we found a higher sensitivity for opioids and AMP/MET in those under 25 years of age compared to other age groups. PPV increased over time for benzodiazepines, AMP/MET and cocaine and FOR was higher during the pilot and POST phases than the GENOA phase.ConclusionOur study highlights the unique challenges associated with ascertaining substance use behaviour for individuals receiving MOUD, indicating many patients will accurately report substance use while others do not. It is therefore important to consider the context of the patient, and the type of the co-substance used to select patient-centred testing as indicated. Therefore, the answer to the question of do we need urine drug screen is yes in some cases.

ABSTRACTObjectiveThis study aims to examine the changes in metabolic profiles in patients with patent foramen ovale (PFO) and migraine, as well as in patients with isolated migraine, before and after surgical intervention using metabolomics.MethodsPatients were categorized into four groups: the simple migraine (SM) group, the PFO with migraine preoperative group (PRE), the PFO with migraine postoperative Day 3 group (POST_3d), and the PFO with migraine postoperative Day 30 group (POST_30d). Untargeted metabolomics using liquid chromatography–mass spectrometry (LC‐MS) were employed to identify differential metabolites across these groups. Differential metabolites were identified, their clinical diagnostic value was assessed, and a correlation analysis was conducted to examine changes in metabolic pathways before and after surgery.ResultsThe expression levels of metabolites such as linoleic acid, quinolinic acid, homophenylalanine, and amphetamine showed significant changes in patients with PFO and migraine following surgery. Notably, linoleic acid demonstrated strong diagnostic potential for this patient population. Trend analysis revealed that the levels of 3‐phenylpropionic acid and caffeine decreased on postoperative Day 3 and subsequently increased by postoperative Day 30, whereas gallic acid continuously declined. Compared to the PRE group, differential metabolites in the SM group were primarily associated with α‐linolenic acid metabolism, niacin and nicotinamide metabolism, sphingolipid signaling, and tyrosine metabolism. In contrast, differential metabolites in the POST_3d group were predominantly enriched in phenylalanine metabolism, niacin and nicotinamide metabolism, protein digestion and absorption, and caffeine metabolism.ConclusionLinoleic acid may serve as a potential biomarker, and the activation of inflammation and oxidative stress‐related pathways could contribute significantly to the development of complicated migraine in patients with PFO.

Assessment of impulsivity using an automated, self-adjusting delay discounting procedure

Article

Author: Pattij, Tommy ; Carr, Madison R ; de Vries, Taco J ; Gómez-Sotres, Paula ; Solinas, Marcello ; van Mourik, Yvar

Modelling delay discounting behavior in rodents is important for understanding the neurobiological mechanisms underlying cognitive control and associated impulsivity disorders. Conventional rodent delay discounting procedures require extensive training and frequent experimenter interaction, as rodents are tested in separate operant chambers away from their home cage. To address these limitations, we adapted and characterize here a self-adjusting delay discounting procedure to an automated CombiCage setup. Rodents were trained during the most active phase of the light-dark cycle, completing 120 trials daily. During each session, we measured large reward preference, mean adjusted delay, and trial participation across multiple delays. Results showed that rodents exhibited discounting behavior after two weeks, with performance stability increasing at 7 weeks training with delay. We also evaluated the influence of altering the consecutive choice criteria (ccc), number of trial choices for a delay step to adjust up or down. Lower ccc (3 vs 8) increased both the number of delay steps encountered per session and task participation. Additionally, we examined the effects of pharmacological interventions, including the psychostimulant amphetamine and the dopamine D1 receptor antagonist, SCH23390. A high dose amphetamine reduced preference for large immediate and short delayed rewards and decreased the mean adjusted delay in a non-dose dependent manner, while SCH23390 did not affect task performance. Together, this novel automated self-adjusting procedure enables high-throughput collection of delay discounting data, with potential applications for investigating impulsivity across the lifespan. However, the current extended session design may limit its suitability for pharmacological evaluations.

Montana: A Trailblazer in Eliminating Regulatory Barriers for Opioid Use Disorder Treatment, According to Community Medical Services

HELENA, Mont., Oct. 24, 2024 /PRNewswire/ -- When the Substance Abuse and Mental Health Services Administration (SAMHSA) updated their recommendations governing Opioid Treatment Programs (OTPs) in April 2024, Montana was among the first to implement significant changes for OTPs in the state. Community Medical Services (CMS) currently provides care to Montana residents at 4 clinics, (Billings, Bozeman, Kalispell and Missoula), and has been working to adjust their clinical guidance to institute these changes aimed at improving patient safety and retention in treatment programs. This is a crucial step forward in addressing the opioid epidemic, providing more effective care for individuals struggling with opioid use disorder. Extended Take-Home Doses Under the new rules, patients are no longer required to come to a clinic at the same frequency as they have historically needed to. Medical providers can determine the appropriate number of take-home doses based on individual patient needs and criteria, including: Absence of active substance use disorders or other health conditions that increase the risk of patient harm Regular attendance for supervised medication administration Absence of serious behavioral problems Absence of known recent diversion activity Safe transportation and storage of take-home medication Higher Initial Dosing The initial dose of methadone, which was historically capped on the first day, can now be titrated more quickly at the medical provider's discretion, allowing patients with higher opioid tolerance to get to a therapeutic dose more quickly. This change acknowledges the varying levels of opioid tolerance among patients, exacerbated by the increased presence of fentanyl in the illicit drug supply, and enables medical providers to tailor treatment to individual needs. Drug Screens The presence of unprescribed amphetamine or cocaine on drug screen results will no longer be the sole limiting factor to requiring patients to not have to come into clinics daily, unless it increases the risk of overdose. This change recognizes that patients with opioid use disorder may also struggle with other substance use disorders and requires medical providers to assess each patient's unique situation. Conclusion The SAMHSA Final Rule changes mark a crucial step forward in enhancing Opioid Treatment Programs in Montana. By providing more flexible and individualized treatment options, these changes aim to improve patient safety and retention, decrease daily patient volumes at clinics, and ultimately support individuals in their journey towards recovery. How CMS is Implementing SAMHSA's Changes At its 4 clinics in Montana, CMS has proactively implemented the SAMHSA Final Rule changes. Our approach focuses on balancing patient safety with reducing barriers to treatment, ensuring that any changes benefit our patients and their recovery outcomes. Triweekly dosing—allowing patients to come to the clinic only three times per week—has become the new standard. This means that most patients, even those who might test positive for stimulants or miss some clinic days, are not required to visit the clinic more than three times a week. For patients who meet certain stability criteria, the option to advance to weekly clinic visits is available after just two weeks of triweekly dosing. This provides immense relief to patients who previously struggled to balance daily trips to the clinic with their other responsibilities, such as work or family.

DEA raises production limits on Takeda's ADHD drug Vyvanse and generics as shortages continue

To address an ongoing shortage of ADHD drugs, the Drug Enforcement Administration has increased the production quota on Takeda's Vyvanse and its generic versions by 24%. Less than four months after Teva’s Adderall was erased from the FDA shortage list, supply problems with another attention-deficit/hyperactivity disorder (ADHD) treatment, Takeda’s Vyvanse and its generic versions, are such that the U.S. Drug Enforcement Administration (DEA) has increased (PDF) production quotas on the drug by 24%.The move comes eight weeks after an FDA request to the DEA to bump up production limits. As Schedule 2 controlled substances, Vyvanse (lisdexamfetamine) and Adderall (amphetamine/dextroamphetamine) are subject to DEA limitations that help prevent them from being abused.The DEA has raised the aggregate production quota on lisdexamfetamine by 6,236 kilograms, according to a final order set to be published Thursday in the Federal Register. Of that figure, 1,558 kg has been allocated to domestic demand for medications, while the remaining 4,678 kg addresses foreign demand for the products.“These adjustments are necessary to ensure that the United States has an adequate and uninterrupted supply of lisdexamfetamine to meet legitimate patient needs both domestically and globally,” the DEA wrote in its notice. Because the drugs are so tightly controlled, there is a ripple effect when one has a supply issue. Shortages of ADHD drugs have persisted since the summer of 2022 when a labor problem on Teva’s packaging line reduced the supply of Adderall. That issue then triggered increased demand and supply issues with most of the 11 companies making generic versions of Adderall, including Sandoz, Amneal and Sun Pharma. Then, in June of last year, Takeda reported in a statement on its website that it was experiencing “low inventory” for Vyvanse brought on by increased demand and a manufacturing delay. In addition, the timing of Vyvanse's shortage raises a question around the economics of producing the medicine in the aftermath of generic launches. Takeda reported its Vyvanse supply shortfall last June, and the first U.S. generics ⁠launched two months later. Lawmakers and industry watchers have repeatedly flagged that ⁠economic factors can drive drug shortages when companies don't see a potential profit motive in dedicating their manufacturing equipment to low-margin—or even loss-making—products. Meanwhile, on the DEA's manufacturing allocation, the agency last summer committed to “reviewing and improving” the quota process. In 2022, that limit was not met, and drugmakers sold only 70% of their allotted quota for the year, making for some 1 billion extra doses that could have been produced, the FDA and the DEA revealed in a joint letter (PDF).At the time, the agencies said they had called on manufacturers to confirm production increases and asked that those that opt to no longer produce the meds “relinquish” their remaining quota so the DEA can redistribute it.

US Justice Dept cracks down on healthcare fraud schemes linked to $2.75bn loss

The US Justice Department has charged 193 people in a major enforcement action, accusing them of participating in healthcare fraud schemes worth $2.75bn. The two-week crackdown involved 76 doctors, nurses, and other medical professionals. The defendants are accused of several scams, such as illegally distributing millions of Adderall (amphetamine) pills and other stimulants. This also included fraudulent activity that involved corporate executives distributing tainted and misbranded HIV medication, which amounted to $90m in losses. Ruthia He, founder and CEO of San Francisco-based digital technology company Done Global, was arrested on 13 June. He has been charged with participating in a scheme to distribute Adderall (amphetamine / dextroamphetamine) over the internet and conspired to commit healthcare fraud in connection with the submission of fraudulent claims for reimbursement for the drug and other stimulants. Adderall is a drug used to treat attention deficit hyperactivity disorder (ADHD). Also included in this crackdown were three executives of a pharmaceutical distributor who allegedly bought HIV medications through fraudulent schemes and resold them with falsified documents to pharmacies nationwide. This led to patients unknowingly receiving mislabelled drugs, one of whom fell unconscious for 24 hours after taking the wrong medication. Attorney General Garland said in a statement: “It does not matter if you are a trafficker in a drug cartel or a corporate executive or medical professional employed by a healthcare company. If you profit from the unlawful distribution of controlled substances, you will be held accountable.” See Also: CHMP recommends authorisation for Pfizer-BioNTech’s Covid-19 vaccine Verona scores FDA approval for Ohtuvayre as COPD maintenance therapy Other instances involve allegations against two owners of wound care firms who allegedly accepted over $330m in kickbacks in a scheme to fraudulently bill Medicare for amniotic wound grafts— biological dressings used to promote the healing of wounds. In Arizona, a woman is accused by prosecutors of improperly billing the state’s Medicaid agency for substance abuse treatment services that either lacked genuine benefit or were never actually administered. The agency announced that they had also seized $230m in cash, luxury vehicles, gold, and other assets in connection with these cases, adding the schemes resulted in $1.6bn in losses. “Through this action, we in federal law enforcement send a clear and strong message—that we will hold accountable those healthcare providers and prescribers who prey on their patients for profit and disregard the first rule of medical care: do no harm,” said US Secretary of Homeland Security Alejandro Mayorkas.
