RESUMO
OBJECTIVE: The objective of this study was to compare trigger point (TrP) dry needling, TrP electroacupuncture and motor point electroacupuncture of the trapezius muscle for the treatment of myofascial pain syndrome (MPS). METHODS: This randomised clinical trial included 90 patients divided into three groups. Group 1 was treated with dry needling of TrPs, group 2 with intramuscular electrical stimulation of TrPs, and group 3 with electroacupuncture of motor points and/or the spinal accessory nerve. Each group received seven treatment sessions. The outcomes were the pain score measured by visual analogue scale (VAS) and quality of life evaluated by the 12-item short form (SF-12) health questionnaire. We compared the pain outcome over serial time points using growth curve analysis methods. RESULTS: Participants in the three groups experienced significant improvements in pain scores over time. The average pain level of participants in group 3 across the repeated assessments was 0.98 units lower than in group 1 (mean difference (95% confidence interval (CI) = 1.74-0.23)), p = 0.012). There were no significant differences in pain scores between participants in groups 1 and 2, and there were no significant differences in quality of life across the three groups at the end of the treatment period. CONCLUSION: Our results provide evidence that electrical stimulation of motor points and/or of the spinal accessory nerve may be superior in terms of pain relief (but not quality of life) to dry needling and possibly electrical stimulation of trigger points for the management of MPS involving the trapezius. TRIAL REGISTRATION NUMBER: TRIAL-RBR-43R7RF (Brazilian Clinical Trials Registry).

BACKGROUND: There are few studies related to Coronavirus Disease 2019 (COVID-19) on the prevalence and nature of pain symptoms after hospital discharge, especially in individuals who develop moderate to severe disease forms. Therefore, this study aimed to evaluate the presence of chronic pain in patients discharged after hospitalization for COVID-19, and the relationship between the presence of chronic pain and intensive care stay, demographics, and risk factors for the worst Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) outcome. METHODS: A cross-sectional observational study was carried out on patients with COVID-19 who recovered after hospitalization. Patients were recruited at the least 3 months after discharge and their hospital's health files were prospected. The variables evaluated were demographics, the severity of SARS-CoV-2 infection (considering the need for intensive care), and the presence of chronic pain. The results were shown in a descriptive manner, and multivariate analysis expressed as Odds Ratios (ORs) and respective Confidence Intervals (CIs) for the outcomes studied. Statistical significance was set at p < 0.05. RESULTS: Of 242 individuals included, 77 (31.8%) reported chronic pain related to COVID-19, with no correlation with the severity of infection. Female sex and obesity were associated with a higher risk for chronic pain with ORs of 2.69 (Confidence Interval [95% CI 1.4 to 5.0]) and 3.02 (95% CI 1.5 to 5.9). The limbs were the most affected areas of the body. CONCLUSION: Chronic pain is common among COVID-19 survivors treated in hospital environments. Female sex and obesity are risk factors for its occurrence.
RESUMO
INTRODUCTION: Chronic pain causes disability and is prevalent in the general population. Opioids are a part of a multimodal strategy for pain management. Methadone, a cheap and long-acting synthetic opioid, may represent an option for those who have limited access to the aforementioned class of analgesics. We aimed to provide a real-world evidence for the analgesic use of methadone, compared with morphine. METHODS: We conducted a noninferiority, retrospective observational single center study of patients with chronic pain, managed with either methadone or morphine at an outpatient specialized clinic. We extracted data from the electronic health records of patients who underwent an active treatment between August 2012 and January 2020 and were examined for at least 2 consecutive medical visits, after the administration of one of the aforementioned drugs. Data were analyzed using a generalized additive model with random-effects mixed linear method to account for the individual-related, time-related, and drug-related variations. The numeric verbal scale (0-10) was used to assess the pain severity. RESULTS: From the database of 3373 patients, we included 262 patients (175 methadone and 87 morphine). In an unadjusted analysis, methadone was superior to morphine, and the mean worst pain was 0.86 points lower (95% confidence interval, -1.29 to -0.43). Moreover, methadone was superior to morphine in the adjusted analysis, with the worst pain mean being 1.24 points lower. This provided evidence for the noninferiority of methadone than morphine. CONCLUSION: Methadone was superior to morphine in a 20% noninferiority margin for reducing worst pain.
RESUMO
OBJECTIVE: This study aimed to investigate the association between professional characteristics and the prevalence of advance directives among palliative care professionals. METHODS: This is a descriptive cross-sectional study. A diverse sample of 327 healthcare professionals completed an online survey investigating demographic variables, length of time working in palliative care, post-graduate qualifications in palliative care, and development of their own advance directives. RESULTS: The prevalence of advance directives among professionals working in palliative care was associated with factors such as higher academic qualifications, holding a post-graduate qualification in palliative care, and working in palliative care for a longer time. Furthermore, psychologists were most likely to have registered their own advance directives, compared with other healthcare professionals. SIGNIFICANCE OF RESULTS: Post-graduate palliative care education and professional experience in this area appear to be important factors associated with palliative care professionals writing of their own advance directives. However, our study suggests that just being involved in or familiar with the context of palliative and end-of-life care does not guarantee that health professionals register their advance directives.

Pain is associated with emotional and physical suffering that severely impacts quality of life. Many guidelines for the treatment of moderate to severe cancer pain indicate the use of opioids. For a small proportion of the global population, opioids are readily accessible, but are consequently also subject to risk of overuse and misuse. On the other hand, many regions provide limited access to licensed opioid therapeutics and patients struggle for better pain management. The use of prescription opioids for treatment of severe cancer and acute pain is well established, but opioid use in chronic non-cancer pain is controversial and not supported by the literature. The opioid crisis and the increasing overdose fatalities in some countries have resulted in a resurgence of opiophobia in these countries, but even worse, amplified opiophobia in countries with lower opioid consumption. In this narrative review, we highlight how the opioid crisis of overuse in some countries can negatively impact appropriate access to opioids elsewhere. The availability of opioids for clinical and recreational use differs between countries worldwide-this is an important factor in determining the occurrence of a 'crisis of recreational use of opioids' or a 'crisis of under-prescription of opioids' for pain management.

OBJECTIVES: The aim of this study was to translate, culturally adapt, and psychometrically evaluate the Brazilian version of the "End-of-Life Professional Caregiver Survey" (BR-EPCS). METHOD: This is an observational cross-sectional study. The sample was composed of 285 Brazilian healthcare professionals who work or worked in the palliative care area. A minimum number of 280 participants were established, following the recommendation of 10 subjects for each instrument item. The European Organisation for Research and Treatment of Cancer - Quality of Life Group Translation Procedure protocol was used for the translation and the cultural adaptation. For the precise/reliable evaluation of factors measured by the BR-EPCS, Cronbach's alpha (α) and composite reliability coefficients were used. The factorial analyses were made by means of the exploratory structural equation modeling methods and confirmatory factor analysis. We have conducted a multiple linear regression analysis to evaluate the sociodemographic variables' capabilities in the result prediction measured by BR-EPCS factors. RESULTS: The factorial analysis showed the relevance of two factors: Factor 1 - "Given care effectiveness" (18 items; Cronbach's α = 0.94; Composite Reliability = 0.95) and Factor 2 - "Mourning and ethical and cultural values" (10 items; Cronbach's α = 0.89; Composite Reliability = 0.88). Multiple linear regression analyses revealed that the working time, sex, palliative care training, and its own advance directives are predictors of the constructs assessed by the BR-EPCS. SIGNIFICANCE OF RESULTS: The BR-EPCS is a reliable, valid, and culturally appropriate tool to identify the educational needs of healthcare professionals who work with palliative care. This instrument can be used for educational and research reasons.

BACKGROUND AND OBJECTIVES: There are few data in the literature characterizing the pattern of analgesic use in Latin American countries, including Brazil. Little is known about the undertreatment of pain and its influence on the habit of self-medication with analgesics. The aim of this study is to define the pattern of analgesic use among chronic pain patients and its potential association with self-medication with analgesics. METHOD: Cross-sectional observational study with an urban population sample. Chronic pain was defined as a pain lasting for at least 90 days. The study was approved by the Research Ethics Committee of the institution. RESULTS: 416 subjects were included; 45.7% (n=190) had chronic pain, with females (72.3%; p=0.04) being the most affected. Self-medication with analgesics is practiced by 78.4% of patients with chronic pain. The most common current analgesic treatment consists of non-steroidal anti-inflammatory drugs (dipyrone and acetaminophen). Weak opioids are rarely used and only 2.6% of subjects with chronic pain were taking these analgesics. None of the subjects were taking potent opioids. CONCLUSIONS: The practice of self-medication with analgesics is frequent among patients with chronic pain, which may be due to the underprescription of more potent analgesics, such as opioids. It can also be said that, given the data presented, there is no crisis of recreational opioid use in the studied population.

BACKGROUND: The N-methyl-d-aspartate receptor antagonist ketamine and its active enantiomer, S(+)-ketamine, have been injected in the epidural and subarachnoid spaces to treat acute postoperative pain and relieve neuropathic pain syndrome. In this study we evaluated the effects of a single dose of preservative-free S(+)-ketamine, in doses usually used in clinical practice, in the spinal cord and meninges of dogs. METHODS: Under anesthesia (IV etomidate (2 mg/kg) and fentanyl (0.005 mg/kg), 16 dogs (6 to 15 kg) were randomized to receive a lumbar intrathecal injection (L5/6) of saline solution of 0.9% (control group) or S(+)-ketamine 1 mg/kg(-1) (ketamine group). All doses were administered in a volume of 1 mL over a 10-second interval. Accordingly, injection solution ranged from 0.6% to 1.5%. After 21 days of clinical observation, the animals were killed; spinal cord, cauda equina root, and meninges were removed for histological examination with light microscopy. Tissues were examined for demyelination (Masson trichrome), neuronal death (hematoxylin and eosin) and astrocyte activation (glial fibrillary acidic protein). RESULTS: No clinical or histological alterations of spinal tissue or meninges were found in animals from either control or ketamine groups. CONCLUSION: A single intrathecal injection of preservative-free S(+)-ketamine, at 1 mg/kg(-1) dosage, over a concentration range of 6 to 15 mg/mL injected in the subarachnoid space in a single puncture, did not produce histological alterations in this experimental model.
