Importance: Driving is a complex occupation requiring the interplay of high-level cognitive, physical, sensory, and behavioral skills for safe performance. Occupational therapists need to routinely address driving with adults as an occupational performance area. Further research is needed to determine whether performance-based assessment tools can support occupational therapists in screening client driving potential.

Psychedelic-assisted therapy (PAT) has shown preliminary efficacy for psychiatric and physical health conditions. Although some people report naturalistic psychedelic use with so-called "underground" practitioners, little is known about PAT that occurs outside of controlled clinical settings or perspectives of these practitioners. We conducted an anonymous online survey of individuals who reported providing psychedelic support services (e.

Weaning age in primates has been challenging to measure and new methods, involving molecular biomarkers in feces, tissue, or teeth have contributed to a solution. Here, we used a direct approach by briefly anesthetizing 442 female toque macaques (Macaca sinica) of Sri Lanka (over a 17-year period) and manually testing their mammary tissue for the presence or absence of milk. Milk tests were related to known offspring ages and maternal care behaviors and indicated that older infants suckled milk well past the weaning age of 7 months that is often reported for food-provisioned primates.

Introduction: In chronic pain conditions such as fibromyalgia (FM), pain amplification within the central nervous system, or "central sensitization," may contribute to the development and maintenance of chronic pain. Chronic pain treatments include opioid therapy, and opioid therapy may maladaptively increase central sensitization, particularly in patients who take opioids long-term. However, it has remained unknown how central sensitization is impacted in patients who use opioids long-term.

Following infection with SARS-CoV-2, a substantial minority of people develop lingering after-effects known as 'long COVID'. Fatigue is a common complaint with a substantial impact on daily life, but the neural mechanisms behind post-COVID fatigue remain unclear. We recruited 37 volunteers with self-reported fatigue after a mild COVID infection and carried out a battery of behavioural and neurophysiological tests assessing the central, peripheral and autonomic nervous systems.

Objective: Chronic pain involves alterations in brain gray matter volume (GMV). Moreover, opioid medications are known to reduce GMV in numerous brain regions involved in pain processing. However, no research has evaluated (1) chronic pain-related GMV alterations in the spinal cord or (2) the effect of opioids on spinal cord GMV.

Neuroimaging research has begun to implicate alterations of brain reward systems in chronic pain. Previously, using functional magnetic resonance imaging (fMRI) and a monetary incentive delay (MID) task, Martucci et al. (2018) showed that neural responses to reward anticipation and outcome are altered in fibromyalgia.

Brain corticostriatal circuits are important for understanding chronic pain and highly relevant to motivation and cognitive processes. It has been demonstrated that in patients with chronic back pain, altered nucleus accumbens (NAcc)-medial prefrontal cortex (MPFC) circuit fMRI-based activity is predictive of patient outcome. We evaluated the NAcc-MPFC circuit in patients with another chronic pain condition, fibromyalgia, to extend these important findings.

Article Synopsis
  • Chronic pain and reward processing are intertwined, but previous research had inconsistent results, especially since sex differences were often overlooked.
  • This study used fMRI to investigate how male and female participants with chronic back pain and healthy controls respond to monetary incentives, focusing on striatal activation.
  • Results showed that healthy males had greater striatal responses to rewards compared to chronic pain males, indicating that chronic pain affects reward processing differently in men versus women, emphasizing the need to consider sex in future studies.

Article Synopsis
  • Major depressive disorder (MDD) and opioid use disorder (OUD) are common genetic disorders that often occur together and can be fatal.
  • A study with 144 healthy participants examined the relationship between genetic risk for these disorders and the behavior of the µ-opioid receptor (MOR) under stress.
  • Findings showed that MDD and OUD genetic risks were linked to how the opioid system activates during stress, particularly in females, indicating a potential pathway for combined treatment approaches.

Unlabelled: Emerging infectious diseases are on the rise in many different taxa, including, among others, the amphibian batrachochytrids, the snake fungal disease and the Severe Acute Respiratory Syndrome coronavirus 2 (SARS-CoV-2) virus, responsible for Coronavirus disease 2019 (COVID-19) in mammals. Following the onset of the pandemic linked to COVID-19, eastern Asia has shown strong leadership, taking actions to regulate the trade of potential vector species in several regions. These actions were taken in response to an increase in public awareness, and the need for a quick reaction to mitigate against further pandemics.

µ-Opioid receptors (MOR) are a major target of endogenous and exogenous opioids, including opioid pain medications. The µ-opioid neurotransmitter system is heavily implicated in the pathophysiology of chronic pain and opioid use disorder and, as such, central measures of µ-opioid system functioning are increasingly being considered as putative biomarkers for risk to misuse opioids. To explore the relationship between MOR system function and risk for opioid misuse, 28 subjects with chronic nonspecific back pain completed a clinically validated measure of opioid misuse risk, the Pain Medication Questionnaire (PMQ), and were subsequently separated into high (PMQ > 21) and low (PMQ ≤ 21) opioid misuse risk groups.

Drivers with medical conditions may need to demonstrate their fitness by participating in clinical and on-road assessments. Scores from the clinic-based occupational therapy-drive home maze test (OT-DHMT) can contribute to fitness-to-drive recommendations. The OT-DHMT is a short, timed test that has previously been shown to be valid and reliable, and norms are available for completion with a driver's dominant hand.

Objective: Despite the heightened urgency of the current prescription opioid crisis, few psychotherapies have been evaluated for chronic pain patients receiving long-term opioid analgesics. Current psychological pain treatments focus primarily on ameliorating negative affective processes, yet basic science suggests that risk for opioid misuse is linked with a dearth of positive affect. Interventions that modulate positive psychological processes may produce therapeutic benefits among patients with opioid-treated chronic pain.

Through autonomic and affective mechanisms, adverse childhood experiences (ACEs) may disrupt the capacity to regulate negative emotions, increasing craving and exacerbating risk for opioid use disorder (OUD) among individuals with chronic pain who are receiving long-term opioid analgesic pharmacotherapy. This study examined associations between ACEs, heart rate variability (HRV) during emotion regulation, and negative emotional cue-elicited craving among a sample of female opioid-treated chronic pain patients at risk for OUD. A sample of women (N = 36, mean age = 51.
