Pain is a private experience, whose assessment relies on subjective self-reporting. Inaccurate communication renders pain evaluation unreliable in individuals with alteration of consciousness, lack of verbal interaction, cognitive dysfunction or simple malingering, hence the importance of developing reliable objective assessment tools.

Cambodian Americans have complex, interrelated and persistent medical and mental health problems stemming from genocide and the social determinants of health. We examined changes in multiple domains of self-reported health outcomes from a diabetes prevention trial.

Transverse myelitis and cerebral venous thrombosis represent some of the described neurological complications of coronavirus disease. A woman in her early 30s presented with headache, left-sided sensory symptoms and voiding difficulty. The patient also reported dry cough, fever, nasal congestion, anosmia and ageusia 2 weeks before presentation. The clinical examination showed sensory disturbances on the left side of the body, starting from the lower abdomen and extending to the left leg, which was consistent with transverse myelitis. The laboratory assessment confirmed a previous infection with coronavirus disease and excluded autoimmune entities. Radiological investigations revealed left transverse sinus thrombosis with no spinal cord abnormalities. The treatment was started with therapeutic anticoagulation and intravenous high-dose steroids. The patient showed significant improvement, and the neurological deficits resolved after 3 months. This is the first documented case of imaging-negative myelitis associated with cerebral venous thrombosis after coronavirus disease.

The structural impact of chronic pain on amygdala in chronic pain (CP) patients remains unclear although major depression and anxiety are known to be associated with its increase and decrease in size, respectively. This study aimed at examining the relationship between emotional stress and amygdala size in CP patients. The effects of mediating and moderating variables were also examined. The PubMed, Embase, and Web of Science databases were searched for English clinical trials from inception to February 2022 using the appropriate keyword strings. We compared the differences in amygdala size assessed with magnetic resonance imaging between CP patients with emotional stress and healthy counterparts. Of the 49 full-text articles identified, 13 studies enrolling 1551 participants including 738 CP patients with emotional stress and 813 controls were analyzed. Emotional stress evaluated with questionnaires based on Beck depression inventory, Hamilton depression/anxiety scale, state-trait anxiety inventory, and hospital anxiety and depression scale revealed significant differences between CP patients with emotional stress and controls, indicating a subclinical but significant level of emotional stress in CP patients. The results demonstrated an amygdala shrinkage among CP patients with emotional stress compared to the controls, especially the right side (p = 0.02). Besides, pain from a single body region was more likely to impact the amygdala size compared to diffuse pain (p = 0.02). Regression analysis revealed no significant association between continuous variables (age, gender, pain duration/intensity) and amygdala size. Our findings demonstrated that emotional stress was associated with a reduced right amygdala size in CP patients.

Patients within the safety net, defined as gap healthcare services for un- or under-insured persons, disproportionately suffer high impact chronic pain. The purpose of this review was to examine pain-related outcomes from multidisciplinary programs for patients with chronic pain within the safety net. A scoping review was conducted based on the Arksey and O'Malley framework coupled with the Preferred Reporting Items for Systematic reviews and Meta-Analyses-Scoping Review checklist. CINAHL, MEDLINE, PubMed, and Google Scholar were searched for eligible articles published between January 1st, 2010 and December 31st, 2020. Grey literature was searched by typing relevant keywords into Google. Quantitative and qualitative outcomes were included. Data collected were charted and analyzed. Ten articles were included, with five demonstrating primarily quantitative results, three demonstrating primarily qualitative results, and the remaining two demonstrating primarily mixed results. Of the studies that utilized qualitative measures, themes included reduction in pain symptoms and the positive reception of a group-based pain management approach. Of the studies that employed quantitative measures, most demonstrated improvements in pain-related outcomes post-intervention, though not all statistically significant. Multidisciplinary pain programs may be of benefit to safety net patients with chronic pain. Further data collection is needed to determine the efficacy of these programs.

In some patients, the inflammatory-immune response to surgical injury progresses to a harmful, dysregulated state. We posit that postoperative systemic inflammatory dysregulation forms part of a pathophysiological response to surgical injury that places patients at increased risk of complications and subsequently prolongs hospital stay. In this narrative review, we have outlined the evolution, measurement and prediction of postoperative systemic inflammatory dysregulation, distinguishing it from a healthy and self-limiting host response. We reviewed the actions of glucocorticoids and the potential for heterogeneous responses to peri-operative corticosteroid supplementation. We have then appraised the evidence highlighting the safety of corticosteroid supplementation, and the potential benefits of high/repeated doses to reduce the risks of major complications and death. Finally, we addressed how clinical trials in the future should target patients at higher risk of peri-operative inflammatory complications, whereby corticosteroid regimes should be tailored to modify not only the a priori risk, but also further adjusted in response to markers of an evolving pathophysiological response.

Headache disorders are globally prevalent and insufficient treatment contribute to low quality of life, increased disability, and socioeconomic costs. However, headache can to a large extent be treated appropriately by general practitioners.

Occupational ApplicationsThe coronavirus disease pandemic has changed the setting of many jobs, forcing people to switch to remote work. In turn, telework is associated with an increased risk of musculoskeletal disorders, as it is difficult to ensure an ergonomically correct work environment at home. Complaints of headaches, neck pain, and dizziness are reported by both young and old people. One of the reasons for such complaints might be an incorrect head position and prolonged tension in the neck muscles that is directly correlated with a spatially misaligned computer monitor and peripherals. We examined biomechanical parameters of the sternocleidomastoid muscle and found that it is possible to reduce tension in this muscle by keeping the head in an appropriate angular range to minimize potential health risks.

Male circumcision is the most common surgical procedure worldwide and is often carried out for religious, cultural, medical and public health reasons. It is commonly performed during the neonatal period. Many studies have now shown that pain is a common intra- and post-operative complication. To ensure proper analgesia during the procedure, many surgeons opt for the use of pacifiers as an adjunct to anaesthesia during neonatal circumcision. The aim of this study is to compare nutritive pacifiers (NPs) versus non-NPs (NNPs) as adjuncts to local anaesthesia in male neonatal circumcision using the Plastibell technique.

Paclitaxel-treated patients frequently experience chemotherapy-induced peripheral neuropathy (CIPN) and mood changes, such as anxiety. Layer II/III of the medial prefrontal cortex (mPFC) is vital for generating pain and emotions. However, it is unclear whether glutamatergic neurons in layer II/III of the mPFC are involved in regulating paclitaxel-induced neuropathic pain and anxiety. Here, we determined the role of glutamatergic neurons in layer II/III of the mPFC in paclitaxel (4 mg/kg/d, consecutive 8 days, intraperitoneal injection, cumulative dose: 32 mg/kg)-induced pain and anxiety by using a combination of behavior testing's, immunostaining, chemogenetics, optogenetics, fiberphotometry, and morphological approaches. The number of c-Fos-positive neurons expressing calcium/calmodulin-dependent protein kinase II (CaMKII) (CaMKII-positive neurons) were increased in layer II/III of the mPFC in paclitaxel-treated mice. Selectively inhibiting CaMKII-positive neurons in layer II/III of the mPFC with chemogenetic or optogenetic approaches relieved paclitaxel-induced neuropathic pain and anxiety. Furthermore, paclitaxel treatment increased calcium signals in layer II/III of the mPFC CaMKII-positive neurons expressed GCaMP6m. In addition, Golgi staining was performed to analize that basal and apical dendrites of pyramidal neurons in layer II/III of the mPFC. Compared with vehicle-treated mice, paclitaxel-treated mice displayed longer and more branches and increased spine density in layer II/III of the mPFC. Further electron microscopy analysis revealed that asymmetrical synapses and postsynaptic density 95 thickness were significantly increased in layer II/III of the mPFC in paclitaxel-treated mice. These data suggest that CaMKII neurons in the mPFC layer II/III are importantly involved in paclitaxel-induced pain and anxiety.
