This study examined perceptions of children and parents about a new web-based CARD (Comfort, Ask, Relax, Distract) game that teaches children how to cope with needle-related pain and fear. A convenience sample of 15 child-parent dyads (children, 6-12 years) participated. Children played the game on a handheld device while being virtually monitored. Activity tracking revealed most children engaged with multiple components. Children reported they understood the game, it was easy to play, they learned coping strategies and believed they could implement them. Children reported lower fear of needles after playing. Parents liked the simplicity and variety of game activities. Most children and parents reported they would use the game or its coping strategies for future needles and would recommend the game. In summary, children and parents found the CARD web game acceptable and appropriate. Future studies can evaluate its effectiveness when integrated into upcoming needle procedures like COVID-19 vaccinations.

Assessing family supportive responses to pain behaviors is paramount, as these may help or hinder chronic pain (CP) adjustment. Current self-report measures of pain-specific family supportive dynamics are scarce, covering a limited range of responses. To address this gap, this paper aimed at the psychometric validation of a (revised) novel measure – the Informal Social Support for Autonomy and Dependence in Pain Inventory (ISSADI-PAIN). Three-hundred and three adults participated in this study (53.3% women; M=49.31), 53.5% with current CP, 20.1% with acute pain (AP) in the previous week and 26.4% with no current pain. All participants completed the revised ISSADI-PAIN. Participants reporting AP/CP in the previous week also filled out measures of pain coping/outcomes. Exploratory and confirmatory factor analyzes supported a 3-factor structure: Perceived Promotion of Dependence (PPD; 5 items; α=.82), Perceived Promotion of Autonomy-Emotional (PPA-Emot; 3 items; α=.78), PPA-instrumental (PPA-Inst; 3 items; α=.82). Higher PPD was associated with higher AP disability and less wellness-focused coping; higher PPA-Emot was associated with more wellness-focused CP coping; PPA-Inst was associated with better/worse AP/CP outcomes and more frequent use of wellness-focused CP coping. Men with AP reported more PPD than women. The revised ISSADI-PAIN is an innovative, valid, and reliable measure of relevant functions of pain-related social support, which may influence pain persistence and adaptation. Perspective: This article presents a novel self-report measure (ISSADI-PAIN) that assesses family support for functional autonomy and dependence in pain contexts. This measure may contribute to further research on the complexities of family supportive dynamics surrounding individuals with AP/CP, clarifying their role on pain persistence and adaptation processes.

Lumbar disc herniation (LDH) is a global issue associated with potentially debilitating long-term consequences, including chronic low back pain (LBP). Short-term outcomes (< 2 years) of LDH patients have been extensively studied and demonstrate improvements in back and leg pain for both operative and conservative management. However, these improvements may not be sustained long-term (>2 years); LDH patients may develop recurrent disc herniations, progressive degenerative disc disease, and LBP regardless of management strategy. Therefore, our objective is to determine the prevalence of chronic LBP after LDH, understand the relationship between LDH and chronic LBP, and investigate the relationship between radiological findings and postoperative pain outcomes.

As the ability to capture single-cell expression profiles has grown in recent years, neuroscientists studying a wide gamut of brain regions have discovered remarkable heterogeneity within seemingly related populations (Saunders et al., 2018a; Zeisel et al., 2015). These "molecular subtypes" have been demonstrated even within brain nuclei expressing the same neurotransmitter (Saunders et al., 2018a; Poulin et al., 2020; Ren et al., 2019; Okaty et al., 2020). Recently, dopamine (DA) neurons of the substantia nigra pars compacta (SNc) and adjacent ventral tegmental area (VTA) have been revealed to be diverse not only when comparing between these two dopaminergic nuclei, but within them, and with the distribution of identified subtypes often agnostic to traditional neuroanatomical boundaries (Saunders et al., 2018a; Hook et al., 2018; Kramer et al., 2018; La Manno et al., 2016; Poulin et al., 2014; Tiklova et al., 2019; Poulin et al., 2018). Such molecularly defined subpopulations have been the subject of several recent studies. Investigations of these subtypes have ultimately unveiled many distinctive properties across several domains, such as their axonal projections and functional properties (Poulin et al., 2018; Wu et al., 2019; Pereira Luppi et al., 2021; Evans et al., 2017; Evans et al., 2020). These key differences between subtypes have begun to corroborate the biological relevance of DA neuron taxonomic schemes. We hypothesize that these putative molecular subtypes, with their distinctive circuits, could shed light on the wide variety of dopamine-related symptoms observed across several diseases including depression, chronic pain, addiction, and Parkinson's Disease. While it is difficult to reconcile how a single neurotransmitter can be involved in so many seemingly unrelated phenotypes, one solution could be the existence of several individual dopaminergic pathways serving different functions, with molecular subtypes serving as distinct nodes for these pathways. Indeed, this conceptual framework is already the dogma for anatomically distinct DA pathways, including the mesocortical, mesolimbic and mesostriatal pathways (Bjorklund & Dunnett, 2007). Here, we discuss our existing knowledge of DA neuron subtypes and attempt to provide a roadmap for how their distinctive properties can provide novel insights into the motor symptoms of Parkinson's disease (PD) (Fig. 1A). By exploring the differences between molecular subtypes and correlating this to their relative degeneration within the SNc, we may gain a deeper understanding of the cell-intrinsic mechanisms underlying why some DA neurons degenerate more than others in PD. Similarly, by mapping the inputs, projections, and functions of individual subtypes, we may better understand their individual roles in the circuit-level dysfunction of dopaminergic diseases.

The present study investigated the involvement of mediodorsal thalamic (MD) GABA-A receptors in cetirizine/morphine-induced anti-allodynia using a rat model of neuropathic pain. To assess the importance of the prefrontal cortex (PFC) for chronic pain processing, its expression level changes of glial fibrillary acidic protein (GFAP) were measured following drug treatments. Each animal was subjected to chronic constriction of the sciatic nerve surgery simultaneously with the MD cannulation under stereotaxic surgery. The results showed that the administration of morphine (3-5mg/kg) or cetirizine (1-3mg/kg) produced significant analgesia in neuropathic rats. Systemic administration of cetirizine (2.5mg/kg) potentiated the analgesic response to a low and intolerance dose of morphine (3mg/kg). Intra-MD microinjection of muscimol, a selective GABA-A receptor agonist (0.005-0.01μg/rat), increased the cetirizine/morphine-induced anti-allodynia, while muscimol by itself did not affect neuropathic pain. The neuropathic pain was associated with the increased PFC expression level of GFAP, suggesting the impact of chronic pain on PFC glial management. Interestingly, the anti-allodynia was associated with a decrease in the PFC expression level of GFAP under the drugs' co-administration. Thus, cetirizine has a significant potentiating effect on morphine response in neuropathic pain via interacting with the MD GABA-A receptors. It seems that neuropathic pain affects the prefrontal cortex GFAP signaling pathway. In clinical studies, these findings can be considered to create a combination therapy with low doses of GABA-A receptor agonist plus cetirizine and morphine to manage neuropathic pain.

In healthy people and people with nonspecific chronic spinal pain (nCSP) and/or insomnia, participation in physical activity on a regular basis has several physical and psychological health benefits. However, people with chronic conditions often tend to reduce physical activity participation which can lead to deconditioning over time. Currently, there are no known predictors for an (in)active lifestyle (before and after physical therapy treatment) in people with chronic spinal pain and comorbid insomnia.

Persistent low back pain (PLBP) is the biggest global cause of disability. Persons with PLBP experience biographic disruption and existential crisis. Guidelines recommend a biopsychosocial approach to management, with the emphasis on coping strategies.

Postoperative pain after video-assisted thoracoscopic surgery (VATS) is common in lung cancer patients, and it is unclear whether cancer itself participates in pain regulation. Programmed cell death ligand-1 (PD-L1) expressed by tumors may be analgesic. Our study aimed to detect the association between PD-L1 and acute postoperative pain.

Although various coronavirus disease 2019 (COVID-19) vaccines have been delivered to the public worldwide, data on cancer populations are limited. Vaccine hesitancy related to safety concerns is observed among cancer patients. We report the perception of COVID-19 vaccines and their safety profile after vaccination among cancer patients.
