Study Objectives: We undertook a study to describe and compare sleep deficiency and symptoms of pain, fatigue, and depressed mood in youth with childhood systemic lupus erythematosus (cSLE) to a healthy comparison group of youth and test the associations between sleep and symptoms of pain, fatigue, and depressed mood in youth with cSLE., Methods: Forty-three youth (23 youth with cSLE; 20 age- and sex-matched healthy youth) wore actigraphs and completed sleep diaries for 10 days and completed self-report questionnaires on sleep quality, pain, fatigue, and depressed mood., Results: On average, both groups had a total sleep time of less than 7 hours. Youth with cSLE had worse sleep efficiency (73.3%) and sleep regularity index scores (55.4) compared to the healthy comparison group of youth (79.2% and 60.1, respectively). Youth with cSLE had worse pain ( P = .03) and fatigue ( P = .004) compared to the healthy comparison group. Negative associations were found among self-reported sleep quality, sleep satisfaction, and symptoms of pain, fatigue, and depressed mood in youth with cSLE and wake after sleep onset was positively associated with fatigue., Conclusions: Poor sleep efficiency and sleep irregularity accompanied by symptoms of pain, fatigue, and depressed mood was prevalent in youth with cSLE. Youth with lupus should be encouraged to maintain a regular sleep schedule. Because this is the first study to incorporate objective sleep and sleep regularity measures in youth with cSLE, additional studies with objective and self-reported sleep measures are needed to replicate our findings., Citation: Wi D, Palermo TM, Stevens A, Ward TM.

Introduction: Pain experience, physical reaction, image quality and adverse events during Gel Instillation Sonohysterography (GIS) can differ using gels with different compositions. As a result, patient satisfaction can also be affected. The effect of two instillation gels, Endosgel versus ExEmgel, using both the Visual Analogue Scale (VAS) and a Continuous Pain Score Meter (CPSM) was therefore compared., Methods: This single centre double blind randomised controlled trial included 80 women planned for outpatient GIS, diagnosed with abnormal intrauterine bleeding or fertility disorders and suspicion on an intrauterine abnormality. Patients were randomly allocated to the instillation of Endosgel containing chlorhexidine or ExEmgel without chlorhexidine. Primary outcome was reported pain during the procedure using VAS. Secondary outcomes included pain score measured using CPSM, satisfaction to the procedure and preference at 3 weeks and 3 months after the procedure and image quality. A cost benefit analysis was also performed., Results: The reported median VAS concerning pain during gel instillation was comparable in the Endosgel and ExEmgel group, 2.50 (IQR 0.00-5.00) and 2.00 (IQR 0.00-5.75) respectively (p = 0.69). The median VAS of the entire procedure was also similar: both 2.00 (IQR 0.00-5.00) (p = 0.86). CPSM-scores were not significantly different either. Both groups were similar in image quality (p = 0.83) and patient's satisfaction (p = 0.36)., Conclusion: Concerning the pain experienced during a GIS procedure and patients' satisfaction, the ExEmgel was not proven to be superior to the Endosgel. Our advice is to use the gel that is available at the lowest costs, as the image quality is the same for both Endosgel and ExEmgel., Competing Interests: Declaration of competing interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2024 The Authors.

The skin injuries pose a substantial public health challenge, not only due to their physical trauma but also the accompanying pain and complexities in wound healing. In the current research, Inula helenium extract and lidocaine were loaded into electrospun PVA/calcium alginate nanofibers to promote skin wounds healing and alleviate the resulting pain. Various in vitro experiments were utilized to characterize these dressings. Wound healing potential of these constructs and their analgesic effects were studied in a rat model of skin wounds. Our developed scaffolds released the loaded drugs in a slow manner and showed antioxidative and anti-inflammatory activities. Fiber size measurement showed that drug-loaded and drug-free scaffolds had around 418.025 ± 140.11 nm and 505.51 ± 93.29 nm mean fiber size, respectively. Bacterial penetration assay confirmed that drug-loaded scaffolds reduced bacterial infiltration through the matrices. Wound healing study showed that on day 14 th , the dressings loaded with inula helenium extract and lidocaine could close the wounds up to 91.26 ± 5.93%. In addition, these scaffolds significantly reduced the animals pain sensitivity. ELISA assay results implied that these dressings modulated inflammation and reduced tissue's oxidative stress., Competing Interests: Declaration of conflicting interestsThe author(s) declared no potential conflicts of interest with respect to the research, authorship, and/or publication of this article.

Sickle cell disease (SCD) is a lifelong monogenic, autosomal-recessive blood disease that predominantly affects individuals of African descent and those who self-identify as Black or Hispanic. Common SCD pathophysiological processes include adhesion, hemolysis, hypoxia, ischemia, oxidative stress, and vaso-occlusion, which often lead to substantial comorbidities and complications. Pain is one of the most common and significant clinical complications for individuals with SCD. Despite advancements in understanding the pathophysiology of SCD, the ways in which SCD pathophysiological processes contribute to nociception and pain signaling, processing, and perception remain largely unclear. Pain management for individuals with SCD is complex and presents unique challenges that must be considered depending on the presenting pain type (eg, acute pain episode vs chronic pain). Racism, stigma (including stigma associated with opioid use), and limited resources present additional challenges. Limited research has been conducted on major clinical features of SCD pain such as its ischemic, inflammatory, and neuropathic components; on its transition from acute to chronic form and across the lifespan; and on factors influencing SCD pain perception. Research on and management of SCD pain requires a whole-person approach, bringing together investigators from multiple disciplines such as hematologists, organ biologists, pain experts, physiologists, neuroscientists, psychologists, geneticists, microbiologists, immunologists, behavioral scientists, and clinicians. Multidisciplinary cross-training, with different platforms for information dissemination and communication, could help promote basic, mechanistic, and translational research to inform the optimization of current treatment strategies and the development of novel therapies for SCD pain. PERSPECTIVE: This review presents the research challenges and negative impact of SCD pain, a grossly understudied condition in a highly underserved population. It also highlights the barriers and opportunities in SCD pain research and could help clinicians better understand current treatment strategies from the whole-person perspective., (Published by Elsevier Inc.)

Background: Intensive care unit (ICU) patients experience several symptoms, yet patterns of symptoms and their relationship with demographic and clinical characteristics have not previously been investigated., Objectives: To identify and compare subgroups (i.e. latent symptom classes) of intensive ICU patients based on prevalence of co-occurring symptoms over seven days., Research Methodology: Prospective cohort study of adult ICU patients' self-reports of five symptoms during seven days in ICU. Latent class analysis was applied to identify subgroups of ICU patients., Setting: Multicenter study with patients from six mixed ICUs in Norway., Main Outcome Measures: Patient Symptom Survey was used to assess five symptoms (i.e., thirst, pain, anxiousness, tiredness, shortness of breath)., Results: Among 353 included patients, median age was 63 years and 60.3 % were male. Subgroups of patients were identified in a Low class (n = 126, 35.7 %), Middle Class (n = 177, 50.1 %) and High Class (n = 50, 14.2 %) based on reporting of the prevalence of five symptoms. Patients in the Low class had a low prevalence of all symptoms. Middle Class patients had a high prevalence of thirst and tiredness and a low prevalence of pain, anxiousness and shortness of breath. The High class patients had a high prevalence of all symptoms. Symptom prevalence remained stable in the Low and Middle class over time and increased over time in the High class. There were significant differences among symptom classes in use of mechanical ventilation (p = 0.012), analgesics (p < 0.001), alpha-2 agonists (p = 0.004) and fluid restriction (p = 0.006). Patients in the High class received more of these ICU-treatments., Conclusions: Findings suggest that subgroups of ICU patients with distinct symptom experiences can be identified. The High prevalence class patients had consistently high levels of all symptoms across seven ICU days and received more ICU-related interventions., Implication for Clinical Practice: Some ICU patients experience a consistently high prevalence of co-occurring symptoms. Clinicians should be aware of treatment factors that could be linked to a high burden of symptoms., Competing Interests: Declaration of competing interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2024 The Authors.

Purpose of this study is to evaluate patient characteristics, treatments and outcomes in bone metastasis radiotherapy practice. Patients for whom radiotherapy for bone metastasis was planned at 26 institutions in Japan between December 2020 and March 2021 were consecutively registered in this prospective, observational study. Study measures included patient characteristics, pain relief, skeletal-related events (SREs), overall survival and incidence of radiation-related adverse events. Pain was evaluated using a numerical rating scale (NRS) from 0 to 10. Irradiated dose was analyzed by the biologically effective dose (BED) assuming α/β = 10. Overall, 232 patients were registered; 224 patients and 302 lesions were fully analyzed. Eastern Cooperative Oncology Group Performance Status was 0/1/2/3/4 in 23%/38%/22%/13%/4%; 59% of patients had spinal metastases and 84% had painful lesions (NRS ≥ 2). BED was <20 Gy (in 27%), 20-30 Gy (24%), 30-40 Gy (36%) and ≥ 40 Gy (13%); 9% of patients were treated by stereotactic body radiotherapy. Grade 3 adverse events occurred in 4% and no grade 4-5 toxicity was reported. Pain relief was achieved in 52% at 2 months. BED is not related to pain relief. The cumulative incidence of SREs was 6.5% (95% confidence interval (CI) 3.1-9.9) at 6 months; no factors were significantly associated with SREs. With spinal lesions, 18% of patients were not ambulatory at baseline and 50% of evaluable patients in this group could walk at 2 months. The 6-month overall survival rate was 70.2% (95% CI 64.2-76.9%). In conclusion, we report real-world details of radiotherapy in bone metastasis., (© The Author(s) 2024.

Background: Neonates undergo numerous painful procedures throughout their hospitalization. Repeated procedural pain may cause adverse long-term effects. Glucose as a non-pharmacological analgesia, is used for neonate pain management. In this study, potential mechanism of attenuate pain induced by glucose in neurodevelopment effect of neonate pain stimulus was investigated., Methods: Neonatal rats to perform a repetitive injury model and glucose intervention model in the postnatal day 0-7(P0-7). Pain thresholds were measured by von Frey test weekly. The puberty behavioral outcome, tissue loss and protein expression in hippocampus were analyzed., Results: Oral administration of glucose after repeated pain stimulation can maintain the hippocampal structure in, and reduce the expressions of corticotropin releasing factor (CFR) and glucocorticoid receptor (GR), therefore, resulted in long-term threshold of pain and cognitive improvement., Conclusion: Exposure to neonatal repeated procedural pain causes persistent mechanical hypersensitivity and the dysfunction of spatial memory retention at puberty. In addition, glucose can relieve these adverse effects, possibly via decreasing CRF/GR levels to change the hypothalamus-pituitary-adrenal (HPA) axis., Competing Interests: Declaration of competing interest The authors declare no competing interests., (Copyright © 2024 The Authors.

Aim: To explore whether ultrasound (US) can be employed to identify the underlying characteristics associated with pain in patients with podagra by evaluating the relationship between ultrasound findings and clinical pain., Material and Methods:  Patients with podagra were recruited and grouped into a pain group (G1, 82 patients) and a non pain group (G2, 123 patients). US features were collected and compared. US data were analyzed by binary logistic regression analysis and ROC analysis. Interobserver reliability was assessed, too., Results: A total of 205 patients (196 male and 9 female) were enrolled in this study. In multivariate analysis, the thickness of the synovium (OR=1.928, CI=1.074-3.463), CD (color Doppler) signal of the synovium (OR=1.458, CI=1.011-2.103), and CD signal of the tophi (OR=1.576, CI=1.142-2.177) were identified as risk factors for clinical pain. Areas under the ROC curves (AUC) were 0.713, 0.686 and 0.641 for the three indicators, respectively. The best cutoff points were 1 mm for the thickness of the synovium, grade 1 for the CD signal of the synovium and grade 2 for the CD signal of the tophi., Conclusions: Ultrasound can provide valuable information for determining underlying features associated with pain in patients with podagra.

Context: Heel prick is one among the common painful procedures in neonates. We performed a systematic review and network meta-analysis (NMA) to compare the efficacy of different interventions for analgesia during heel prick in neonates., Evidence Acquisition: Medline, Cochrane, Embase and CINAHL databases were searched from inception until February 2023. Randomized and quasi-randomized trials that evaluated different pharmacological and non-pharmacological interventions for analgesia during heel prick for neonates were included. Data from the included trials were extracted in duplicate. A NMA with a frequentist random-effects model was used for data synthesis. Certainty of evidence (CoE) was assessed using GRADE. We adhered to the PRISMA-NMA guidelines., Results: One-hundred-and-three trials comparing 51 different analgesic measures were included. Among the 38 interventions, for pain "during" heel prick, non-nutritive suckling (NNS) plus sucrose [SMD -3.15 (-2.62, -3.69)], followed by breastfeeding, glucose, expressed breast milk (EBM), sucrose, NNS and touch massage, had a high certainty of evidence (CoE) to reduce pain scores when compared to no intervention. Among the 23 interventions for pain at 30 seconds after heel-prick, moderate CoE was noted for facilitated tucking plus NNS plus music, glucose, NNS plus sucrose, sucrose plus swaddling, mother holding, EBM, sucrose and NNS., Conclusions: Oral sucrose 2 minutes before combined with NNS during the procedure, was the best intervention for reducing pain during heel prick. It also effectively reduced pain scores 30 seconds and 1 minute after the procedure. Other interventions with moderate to high CoE for a significant reduction in pain during and at 30 seconds after heel prick are oral sucrose, oral glucose, EBM and NNS. All these are low-cost and feasible interventions for most of the settings.

Pain is a prevalent symptom among cancer patients and survivors. Psychoactive substance use (PSU) is associated with both the presence and severity of pain. However, little is known about this association in the context of cancer. The primary objective was to compare the prevalence of PSU and its relationship with pain during and after cancer. PSU was defined as the use of nonmedication substances (alcohol, tobacco, e-cigarettes, cannabidiol, and cannabis), with frequency categorized as at least yearly, monthly, weekly, or daily. Secondary objectives aimed to explore the relationships between PSU and pain characteristics, health-related quality of life, anxiety, depression, deprivation, and individual characteristics. Among the 1041 individuals included, pain prevalence was 44.7% (95% confidence interval [CI] 41.6%-47.8%). The overall prevalence of PSU at least monthly was 67.0% (95% CI 64.0%-69.8%). The proportions of chronic and neuropathic pains were higher for at least monthly use of cannabidiol compared to nonuse (70.0% vs. 39.3% and 55.7% vs. 28.1%, p < .001). In multivariate analysis, the monthly uses of tobacco and cannabidiol were higher in painful individuals than in nonpainful ones (odds ratio: 2.85 [95% CI 1.22-6.64] and 3.76 [95% CI 1.13-12.44], p < .05). From the point of view of the patient care, the study underscores the need for physicians to prioritize smoking cessation and pay attention to the use of cannabidiol during and after cancer., (© 2024 UICC.)

Background: Trigger finger, or stenosing tendovaginitis, is one of the most common causes of hand disability, where a finger or thumb painfully snaps and locks due to a tendon-sheath size mismatch at the A1 pulley. The exact aetiology of trigger finger is unknown, though it is associated with factors like diabetes, rheumatic disease and carpal tunnel syndrome. The main purpose of this prospective study was to explore clinical characteristics and comorbidities in a cohort of 139 patients who underwent surgery for trigger finger and find factors of importance for the outcome 1 year postoperatively., Methods: Pain, range of motion, hand function evaluated by the Disabilities of the Arm Shoulder and Hand questionnaire as well as Quinnell grade of triggering were examined preoperatively. Symptom duration, working status, medical history and comorbidities at baseline were also noted. Further, range of motion was evaluated 3 months after surgery, pain and hand function were evaluated 3 and 12 months after surgery. An outcome scale with three levels was defined. The development of any new comorbidities was monitored during an extended postoperative observation period, with a mean duration of 70 months (range: 56-88 months)., Results: Poor outcome was strongly associated with younger age ( P = 0.0009), a high level of preoperative pain in the operated hand ( P = 0.0027), psoriatic arthritis ( P = 0.021) and atopic disease ( P = 0.028; odds ratio [OR]: 3.87, 95% confidence interval [CI]: 1.15-13.04). A low range of motion preoperatively did not affect the outcome. Carpal tunnel syndrome was the most common comorbidity but did not affect the outcome. A good preoperative range of motion, good hand function and less pain were associated with better outcomes., Conclusion: Younger age, a high level of preoperative pain, psoriatic arthritis and atopic disease were factors associated with a worse outcome of trigger finger surgery. Pain and disability decreased 3 months postoperatively and continued to decrease between 3 and 12 months., Competing Interests: The authors report no conflict of interest., (© 2024 The Author(s).

Objective: To analyze the effect of breastfeeding on reducing Pentavalent vaccination pain in infants and to identify the necessary breastfeeding interval for antinociceptive action., Method: Open parallel randomized clinical trial. Ninety mother-infant dyads participated, distributed into intervention group 1 (n = 30), which breastfed five minutes before vaccination; intervention group 2 (n = 30), which breastfed five minutes before and during vaccination; and control group (n = 30), which did not breastfeed. The outcome variable was the pain level measured by the FLACC Scale. Data analysis was conducted using descriptive and inferential statistics, applying Fisher's Exact, Kolmogorov-Smirnov, Kruskal-Wallis and Dunn's multiple comparison tests, with 0.05 significance level., Results: Pain induced by the Pentavalent vaccine was reduced in intervention groups 1 and 2 (mean pain of 6.06 versus 3.83, respectively) compared to the control group (mean of pain of 7.43), which was significant for intervention group 2 (p < 0.001), indicating that, to achieve lower levels of pain, breastfeeding should be carried out before and during vaccination., Conclusion: Longer breastfeeding, conducted five minutes before and during vaccination, reduces the pain induced by the Pentavalent vaccine. No vaccination risks were identified to outweigh the benefits. These results endorse that health professionals should encourage breastfeeding at least five minutes before and during vaccine injection for an antinociception effect.

Background: Venipuncture is one of the most commonly performed medical procedures in paediatric care, but it can also be one of the most painful and distressing experiences for patients. Finding effective strategies to manage pain and fear associated with venipuncture is crucial for improving the paediatric patient experience and promoting positive health outcomes. This study aimed to evaluate the efficacy of a combined approach using a topical analgesic cream (TKTX cream) and a distraction technique (Trace Image and Colouring for Kids-Book, TICK-B) in reducing pain intensity and fear levels in children undergoing venipuncture procedures., Methods: We conducted this randomised controlled trial among 176 children aged 6-12 years undergoing venipuncture. Participants were randomly assigned to four groups: TICK-B, TKTX cream, TICK-B+TKTX cream and a control group. Pain and fear were measured using the Wong-Baker FACES Pain Rating Scale and Children's Fear Scale. The study was carried out from 20 February 2024 to 1 June 2024 at the emergency unit of Heevi paediatric teaching hospital in the Kurdistan region of Iraq. In the intervention groups, TICK-B was applied for 2-3 min before needle insertion, and TKTX cream was applied 20 min before the venipuncture procedure. All outcome measures were evaluated 2-3 min after the completion of the venipuncture procedure., Results: The combined TICK-B (colouring book) and TKTX cream (topical anaesthetic) intervention was the most effective in reducing both pain intensity (mean score 2.80 vs 7.24 in the control, p<0.001) and fear levels (mean score 0.93 vs 2.83 in the control, p<0.001) during and after venipuncture procedures compared with individual interventions and control., Conclusions: The combined TICK-B distraction and TKTX cream topical anaesthetic intervention was the most effective in reducing pain intensity and fear during and after venipuncture in children, providing a practical strategy for healthcare providers to optimise needle procedure management., Trial Registration Number: NCT06326125., Competing Interests: Competing interests: None declared., (© Author(s) (or their employer(s)) 2024.

Pain is a widespread and troubling clinical and social problem with important effects on society and individuals. The purpose is to assess the relationship between pain and eating behavior, macro-micronutrient intake, and dietary inflammation index. The study was carried with a total of 80 patients, consisting of 40 patients diagnosed with pain and 40 patients not diagnosed with pain, who applied to a private hospital in Istanbul as outpatients with a questionnaire face-to-face consisting of questions about sociodemographic characteristics, anthropometric measurements, pain-related information, Eating Attitude Test (EAT-19), and 24-hour food consumption record. The statistical analysis of the data was conducted with SPSS v27 package program. People who had pain had higher levels of disrupted eating attitudes than those who did not have pain. The "Bulimia" subfactor mean score of the EAT-19 was higher in those with pain (P < .05). No difference was found between the case-control groups regarding the mean dietary inflammation index (DII) score and energy, macro- and micronutrient consumption values (P > .05). No difference was detected between the case-control groups with disrupted eating attitudes regarding the median DII score (P > .05). The median DII score was significantly higher in individuals with pain and normal eating attitudes than in those without pain and with disrupted eating attitudes (P < .05). There is a relationship between pain, eating attitudes, and DII, the median DII score of those who had pain and had normal eating attitudes was higher., Competing Interests: The authors declared no potential conflicts of interest with respect to the research, authorship, and/or publication of this article., (Copyright © 2024 the Author(s).

In a randomized, controlled study, whole-body electromyostimulation (WB-EMS) was investigated as a promising alternative treatment technique compared to conventional strength training for the management of knee osteoarthritis (OA). Seventy-two overweight participants with symptomatic knee OA were randomly assigned to WB-EMS (n = 36) or a usual care group (UCG, n = 36). For seven months, the WB-EMS group received three times per fortnight a WB-EMS training, while the UCG was prescribed six-times physiotherapeutic treatments. We observed significant effects for the primary outcome "pain", as determined by the Knee injury and Osteoarthritis Outcome Score (KOOS), with more favourable changes in the WB-EMS group vs UCG (between-group difference 9.0 points, 95%CI 2.9-15.1, p = 0.004). Secondary outcomes, including the other KOOS subscales (symptoms, function in daily living, function in sports/recreational activities and quality of life), 7 day pain diary, hip/leg extensor strength and lower limb function (30s sit-to-stand test), were also statistically significant in favour of the WB-EMS group. Overall, WB-EMS was found to be effective in relieving knee pain symptoms and improving physical function in individuals with symptomatic knee OA compared to usual care treatment. WB-EMS could be used as an alternative therapy in the management of knee OA; particularly for patients that cannot be motivated for conventional training., (© 2024. The Author(s).)

Background: The use of self-report pain scales in persons with aphasia can be challenging due to communication and cognitive problems, while for assessing pain self-report pain is considered the gold standard (Harrison RA, Field TS. Post stroke pain: identification, assessment, and therapy. Cerebrovasc Dis. 2015;39(3-4):190-201.). An observational scale may be used as an alternative. This study examines the validity and reliability of the observational Pain Assessment in Impaired Cognition (PAIC15) scale in persons with aphasia., Methods: Persons with aphasia were observed during rest and transfer by two observers using the PAIC15. The PAIC15 comprises 15 items covering the three domains of facial expressions, body movements, and vocalizations. When able, the participant completed four self-report pain scales after each observation. The observations were repeated within one week. For criterion validity, correlations between the PAIC15 and self-report pain scales were calculated and for construct validity, three hypotheses were tested. Reliability was determined by assessing internal consistency, and intra- and interobserver agreement., Results: PAIC15 observations were obtained for 71 persons (mean age 75.5 years) with aphasia. Fair positive correlations (rest: 0.35-0.50; transfer: 0.38-0.43) were reported between PAIC15 and almost all self-report pain scales. Results show that significantly more pain was observed in persons with aphasia during transfer than during rest. No differences were found for observed pain between persons with aphasia who use pain medication and those without, or persons who have joint diseases compared to those without. Results showed acceptable internal consistency. Intra- and interobserver agreement was high for most PAIC15 items, particularly for the domains body movements and vocalizations during rest and transfer., Conclusions: Recognition of pain in persons aphasia using the PAIC15 showed mixed yet promising results., (© 2024.

Abstract: There is an urgent and unmet clinical need to develop nonpharmacological interventions for chronic pain management because of the critical side effects of opioids. Low-intensity transcranial focused ultrasound (tFUS) is an emerging noninvasive neuromodulation technology with high spatial specificity and deep brain penetration. Here, we developed a tightly focused 128-element ultrasound transducer to specifically target small mouse brains using dynamic focus steering. We demonstrate that tFUS stimulation at pain-processing brain circuits can significantly alter pain-associated behaviors in mouse models in vivo. Our findings indicate that a single-session focused ultrasound stimulation to the primary somatosensory cortex (S1) significantly attenuates heat pain sensitivity in wild-type mice and modulates heat and mechanical hyperalgesia in a humanized mouse model of chronic pain in sickle cell disease. Results further revealed a sustained behavioral change associated with heat hypersensitivity by targeting deeper cortical structures (eg, insula) and multisession focused ultrasound stimulation to S1 and insula. Analyses of brain electrical rhythms through electroencephalography demonstrated a significant change in noxious heat hypersensitivity-related and chronic hyperalgesia-associated neural signals after focused ultrasound treatment. Validation of efficacy was carried out through control experiments, tuning ultrasound parameters, adjusting interexperiment intervals, and investigating effects on age, sex, and genotype in a head-fixed awake model. Importantly, tFUS was found to be safe, causing no adverse effects on motor function or the brain's neuropathology. In conclusion, the validated proof-of-principle experimental evidence demonstrates the translational potential of novel focused ultrasound neuromodulation for next-generation pain treatment without adverse effects., (© 2024 American Society of Hematology.

Aim: Pain and anxiety levels in palliative care patients negatively impact their quality of life, highlighting the need for research on non-pharmacological methods. This study aimed to evaluate the effects of music and aromatherapy interventions on pain, anxiety, and stress levels in these patients., Material and Methods: The research was designed as a single-blind, four-group, randomized controlled trial. The sample consisted of 88 patients hospitalized in a palliative care center (receiving palliative care services with terminal or advanced diseases). Patients were randomly assigned to four groups (n = 22, music, aromatherapy, music and aromatherapy, and control group). Patients in the experimental groups received the intervention to which they were assigned for 20 min each day for three consecutive days: music, aromatherapy, or music accompanied by aromatherapy. No intervention was applied to the control group. The patients' levels of pain, anxiety, and stress were assessed before and after the intervention using the Visual Analog Scale (VAS), the Facial Anxiety Scale (FAS), and the Distress Thermometer., Results: No significant differences were found in the demographic characteristics of the groups (p > 0.05). The Wilcoxon Signed-Rank and Kruskal-Wallis tests indicated statistically significant differences in pre- and post-intervention scores for VAS, FAS, and Distress across all experimental groups on all follow-up days (p < 0.05)., Conclusion: Implementing music, aromatherapy, and their combination effectively reduced pain, anxiety, and stress levels in palliative care patients, suggesting these non-pharmacological interventions can improve their quality of life., Trial Registration: ClinicalTrails.gov (Registration number: NCT06024954) at 05-SEP-2024., (© 2024.

Background: Paediatric circumcision is a standard surgical procedure that frequently induces anxiety, fear, and pain in young patients. Child-friendly nursing has shown potential in alleviating psychosocial distress in paediatric care settings. However, its specific impact on patients undergoing circumcision remains underexplored. This study aimed to evaluate the effectiveness of child-friendly nursing in reducing patients' anxiety, fear and pain in patients undergoing paediatric circumcision., Methods: Clinical data of paediatric patients who underwent circumcision at Taizhou Hospital of Zhejiang Province from January 2022 to November 2023 were retrospectively analysed. Patients were divided into the traditional nursing (January 2022 to December 2022) and child-friendly nursing (January 2023 to November 2023) groups. Psychosocial parameters, including anxiety, depression, pain, and fear, were assessed using the Children's Anxiety Meter-State (CAM-S), Children's Depression Inventory (CDI), Wong-Baker FACES Pain Rating Scale (WBFPRS), and Children's Fear Scale (CFS), respectively., Results: No significant differences were found in CAM-S, CDI, WBFPRS, and CFS scores between the two groups before intervention ( p > 0.05). However, post-intervention scores for all parameters in the child-friendly nursing group were significantly lower than those in the traditional nursing group ( p < 0.001). The results suggest that child-friendly nursing effectively reduces anxiety, depression, fear and pain in children undergoing circumcision., Conclusions: This study provides compelling evidence supporting the effectiveness of child-friendly nursing in enhancing surgical experiences and improving psychosocial outcomes for paediatric patients undergoing circumcision., Competing Interests: The authors declare no conflict of interest., (© 2024 The Author(s).)

To examine the relationship between Achilles-tendon (AT) and patellar-tendon (PT) structure, clinical-examination and tendon pain in young gymnasts; and, to explore the associations between these factors and age, maturation, and training-load. Two hundred and seventy-four female gymnasts (aged 12.1±1.9 yrs) were assessed for anthropometric measures, pubertal-stage, and training-load. They had clinical-tests (pain-on-palpation for AT and pain-on-palpation and Royal-London Hospital-Test for PT), were asked about tendon-pain during-loading and were assessed for tendon-structure. Gymnasts with positive clinical-tests (with and without pain during-loading) presented a significantly higher prevalence of disorganized AT and PT compared to gymnasts with negative clinical-tests (with and without pain during-loading) ( p <0.05). A significant pubertyXpositive clinical-test interaction was found for disorganized PT structure, whereby a disorganized structure was more prevalent among post-pubertal gymnasts with positive clinical-tests compared to pre-pubertal participants with negative clinical-tests (F (1, 263) =9.436, p =0.002). In gymnasts with positive clinical-tests, significant correlations were found between disorganized AT and PT structures and age, and training-load ( p <0.05). An increased prevalence of disorganized tendon structure (regardless of pain during-loading) was seen in participants with positive clinical-tests. This disorganized tendon-structure was found to be significantly related to increased age, post-pubertal stage, and higher training hours in gymnasts with positive clinical-tests.

C-C Motif Chemokine Ligand 17 (CCL17) is a chemokine that binds and signals through the G-protein coupled CC-chemokine receptor 4 and has been implicated in the development of inflammatory and arthritic pain. GSK3858279 is a high-affinity, first-in-class, monoclonal antibody, binding specifically to CCL17 and inhibiting downstream signaling. In this phase I, randomized, single-center, double-blind, placebo-controlled, three-period, incomplete-block crossover study (NCT04114656), the analgesic effects and safety of intravenous GSK3858279 were assessed in a battery of evoked acute pain assessments on healthy, adult (aged ≥18 years), male participants. Participants were randomized 1:1 to receive either one placebo (0.9% w/v NaCl) dose followed by two GSK3858279 doses (PAA treatment sequence), or one GSK3858279 dose followed by two placebo doses (APP treatment sequence). The co-primary end points were ultraviolet B heat pain detection threshold (°C), cold pressor time to pain tolerance threshold (PTT, sec), and electrical PTT (mA, single stimulus). Twenty-one participants were enrolled (PAA = 11; APP = 10). Mean age (standard deviation) was 29.3 (7.9) years for PAA, 31.1 (7.7) years for APP. No significant differences were observed in the analgesic effect between GSK3858279 and placebo for any end point. Exposure to GSK3858279 was similar between Period 1 (APP sequence), and Periods 2 and 3 (PAA sequence), with some GSK3858279 carry-over. Changes in serum CCL17 levels were consistent with the expected GSK3858279 activity. All drug-related adverse events were mild in intensity and caused no discontinuations. The absence of an efficacy signal in this acute pain model does not preclude efficacy in chronic pain states., (© 2024 GSK.

Objective: To examine the relationship between C-reactive protein (CRP) and knee pain, and further explore whether this association is mediated by obesity., Methods: The population was derived from 1999 to 2004 National Health and Nutrition Examination Survey. Logistic regression was used to analyze the relationship between CRP and knee pain in three different models, and the linear trend was analyzed. A restricted cubic spline model to assess the nonlinear dose-response relationship between CRP and knee pain. Mediation analyses were used to assess the potential mediating role of obesity. Subgroup analyses and sensitivity analyses were performed to ensure robustness., Results: Compared with adults with lower CRP (first quartile), those with higher CRP had higher risks of knee pain (odds ratio 1.39, 95% confidence interval 1.12-1.72 in third quartile; 1.56, 1.25-1.95 in fourth quartile) after adjusting for covariates (except body mass index [BMI]), and the proportion mediated by BMI was 76.10% (p < .001). BMI and CRP were linear dose-response correlated with knee pain. The odds ratio for those with obesity compared with normal to knee pain was 2.27 (1.42-3.65) in the first quartile of CRP, 1.99 (1.38-2.86) in the second, 2.15 (1.38-3.33) in the third, and 2.92 (1.72-4.97) in the fourth., Conclusion: Obesity mediated the systemic inflammation results in knee pain in US adults. Moreover, higher BMI was associated with higher knee pain risk in different degree CRP subgroups, supporting an important role of weight loss in reducing knee pain caused by systemic inflammation., (© 2024 The Author(s).

Objective: This study was designed to compare discomfort/pain after periodontal and peri-implant probing in patients with titanium compared with zirconium implants., Methods: One examiner recruited and examined 70 patients, each of whom had a dental implant with a contralateral tooth; 37 patients had titanium implants of various types and 33 patients had zirconium implants; one implant was analyzed for each patient. Periodontal and peri-implant probing pocket depth (PPD) and clinical attachment level (CAL) were assessed. Immediately after probing, patients rated their discomfort/pain with a visual analog scale (VAS). The emergence profiles of implant crowns were assessed on periapical radiographs of the implants., Results: Seventy patients with a median age of 55 years (interquartile range [IQR]: 42-65 years), including 43 females and 16 current smokers, were examined. The mean PPD and bleeding on probing (BOP) were higher around implants than around teeth (p < .001). CAL and suppuration were well-balanced between implants and teeth. Peri-implant probing caused significantly more discomfort/pain than periodontal probing [median VAS score: 12.5 (IQR 4-22) vs. 9 (2-15); p < .001]. Logistic regression revealed that discomfort/pain after peri-implant probing was less intense in patients who had taken analgesic medication (p = .021) and around titanium implants (p = .037)., Conclusions: Peri-implant probing caused significantly more discomfort/pain than periodontal probing. Patients who had taken analgesic medication experienced less discomfort and pain with peri-implant probing than those who had not; furthermore, titanium implants were associated with less pain than zirconium implants., (© 2024 The Author(s).

Heel pain is a prevalent issue in young athletes, often arising from overuse and increased sporting demands. While Sever's Disease is the predominant cause, various other entities, including stress-related injuries and pathologies like tumors and bone lesions, contribute to this condition. The complex hind foot anatomy, encompassing ossicles, physis, and soft tissues, may lead to heel pain. This study aims to provide physicians with a clinically oriented narrative review of adolescent heel pain, supported by illustrative cases. CONCLUSION: This study aims to offer physicians a comprehensive understanding of the concepts surrounding heel pain in adolescents. By presenting clinically relevant information and illustrated cases, it seeks to enhance medical practitioners' ability to diagnose and manage heel pain effectively in this specific demographic., Competing Interests: Declaration of Competing Interest Authors declare that they have no conflict of interest., (Copyright © 2024 Elsevier Ltd.

Introduction: Sickle cell disease is an inherited disorder characterized by hemoglobin S polymerization leading to vaso-occlusion and hemolytic anemia. These result in a variety of pathological events, causing both acute and chronic complications. Millions around the world are affected by sickle cell disease with predominance in sub-Saharan Africa. Hydroxyurea was the first drug approved for use in sickle cell disease to reduce the occurrence of painful crises and blood transfusions in patients with frequent, moderate to severe painful crises., Areas Covered: With the development of new therapeutics, the role of hydroxyurea is evolving. This narrative review aims to provide clinical data, safety information, and supplementary evidence for the role of hydroxyurea in the current era of sickle cell disease. A comprehensive literature search of databases, including PubMed and Cochrane Library, was conducted from 1963 to 2024., Expert Opinion: Even though new medications have been approved for sickle cell disease, hydroxyurea remains the gold standard. Hydroxyurea is not only a disease modifier but it has additional clinical benefits, it is affordable, and its longevity has prompted expanded research in areas such as underutilization and pharmacogenomics. As the treatment landscape evolves, hydroxyurea's long-standing record of efficacy and safety continues to support its role as a key agent in disease management.

Introduction: Rheumatoid arthritis (RA) is a chronic inflammatory disease characterized by symmetric polyarthritis. RA is routinely treated by various systemic drugs; on the other hand, administration of intra-articular corticosteroids or different types of synovectomies can be used in case of systemic medication's failure. Chemical, radio isotopic, and surgical synovectomies are being used as therapeutic options for chronic synovitis to improve joint function. Chemical synovectomy is not well tolerated, and the long-term response is relatively low. Surgical synovectomy has a better success rate, but it recommends higher expenses. In radiation synovectomy, radioactive labeled particles are applied directly in the articular cavity, followed by homogeneous distribution in joint. Next, the radioactive particles are transported in the depth of synovia and phagocytized by inflammatory cells. Finally, the radiation leads to fibrosis and sclerosis of formerly inflamed synovial membrane; thus, it stops the inflammation and reduces the symptoms. It has a success rate of 40-100% and its effect can be similar to surgical synovectomy., Materials and Methods: Thirty-one patients with resistant monoarthritis of the knee were enrolled in this study. One millicurie of phosphorus-32 was injected into patients' knee via US guide. Saline was injected afterwards to prevent leakage. Direct pressure was performed after removing the needle and the knee was flexed slowly to ensure homogenous distribution and fixed with a splint for 1 to 2 weeks. Patients were followed up after 2 weeks, 1 month, 2 months, and 6 months. The following variables were assessed by the treating rheumatologist: patients' pain, joint tenderness, effusion, and ROM. At the time of injection and after the first week, patients were investigated for any complication including infection, necrosis, pain, and swelling. The effect of clinical characteristics and demographic data on existing complications and the changes of pain, joint tenderness, effusion, and ROM was assessed., Results: Thirty-one patients with the mean age of 54.5 ± 12.2 years and the mean disease duration of 12 ± 6.5 years were enrolled in this study. Mean DAS-28 ESR score for our patients was 4 ± 0.7. The pain, effusion, and reduced ROM were decreased significantly after all follow-up intervals. Knee tenderness was not affected in the first 2 weeks, but it was reduced significantly after 1, 2, and 6 months. No serious complications like infection and necrosis were reported through our study. 51.6% and 54.8% of our patients reported pain and swelling in the administration site. Furthermore, 19.4% and 16.1% of patients reported deterioration of pain and effusion in the first week of injection., Conclusion: In our study, we demonstrated that pain, tenderness, effusion, and ROM are improved after radiation synovectomy with phosphorus-32. We also showed that there was no serious adverse effect like infection and necrosis. However, more than half of our patients experienced pain and swelling of injection site at the time of administration. Key points • We demonstrated the efficacy of radiation synovectomy as a medication for monoarthritis. • The results of our study can lead to a bigger clinical trial to assess the benefits and adverse effects of radiation synovectomy in comparison to treatment with local or systemic corticosteroids., (© 2024.

Purpose of Review: This focused, narrative review mostly describes our team's investigations into the potential inflammatory mechanisms that contribute to the development of cancer-related gastrointestinal (GI) mucositis and its associated symptoms. This review summarizes details of our clinical and preclinical findings to test the role of inflammation in the development and occurrence of these cancer-related conditions., Recent Findings: GI mucositis (GIM) is a common, distressing condition reported by cancer patients. GIM is often clustered with other behaviors including fatigue, pain, anorexia, depression, and diarrhea. It is hypothesized that there is a common biologic mechanism underpinning this symptom cluster. Our multi-platform investigations revealed that GIM and its associated cluster of behaviors may be triggered by local inflammation spreading systemically causing pro-inflammatory-mediated toxicities, leading to alterations in immune, metabolic, and nervous system functions and activities. For example, behavioral toxicities related to local irradiation for non-metastatic cancer may be triggered by mGluR5 activation influencing prolonged T cell as well as NF-κB transcription factor activities. Thus, interventions targeting inflammation and associated pathways may be a reasonable strategy to alleviate GIM and its symptom cluster., Summary: GIM may be a sign of a broader systemic inflammatory response triggered by cancer or its treatment. Addressing GIM and its associated symptoms primarily involves supportive care strategies focused on relieving symptoms, promoting healing, and preventing complications., (Copyright © 2024 The Author(s).

Background: Abnormal uterine bleeding (AUB) affects women of all ages and is one of the most common reasons for referral to a gynaecological clinic. Operative hysteroscopic procedures allow for a see-and-treat approach to AUB, and these techniques have been shown to be feasible and acceptable in the outpatient setting., Objective: To assess if there is an increase in pain scores for women who are undergoing an operative hysteroscopic procedure with Myosure LITE® (Hologic; mechanical hysteroscopic tissue removal system) compared to outpatient diagnostic hysteroscopy alone., Study Design: A prospective cohort study was performed. All participants attending the outpatient hysteroscopy clinic at Mercy Hospital for Women completed a pre-and post-procedure questionnaire. This included a visual analogue scale (VAS) for any pre-existing pain, anticipated pain, and actual pain experienced during procedure. Factors influencing overall satisfaction and willingness to attend again were also assessed. Data was entered into RedCap® for analysis. A difference in VAS of 10 mm or more was considered clinically significant. An alpha of p < 0.05 was assigned for statistical significance., Results: Between February 2020 and November 2022, 208 women underwent outpatient diagnostic hysteroscopy followed by an operative hysteroscopy with MyoSure®. To allow for standardisation of analgesia, only participants who had a cervical block before their Myosure® procedure were included for analysis (n = 111). There was statistical evidence (t(111) = 2.36, p = 0.02) of a lower mean VAS pain score for operative Myosure (36.5 mm, 95 % CI: 31.1-41.8 mm) compared to outpatient diagnostic hysteroscopy (44.1 mm, 95 % CI: 39.0-49.2 mm). The mean difference in VAS pain score was estimated as 7.7 mm (95 % CI: 1.2-14.1 mm) lower for Myosure compared to hysteroscopy. Given the threshold for clinical significance was considered as 10 mm difference in VAS, the variance in pain scores is under the likely clinically significant range. There was no significant difference in pain scores for diagnostic hysteroscopy with or without paracervical block (mean difference = 1.42; 95 % CI: -6.35 to 9.20). There was no association between pre-existing pain, and actual pain for hysteroscopy, or Myosure (p = 0.997 and p = 0.065 respectively). The anticipated pain score was weakly associated with actual pain during the operative Myosure procedure (p = 0.02), and with outpatient diagnostic hysteroscopy (p = 0.019)., Conclusion: Outpatient hysteroscopy procedures are generally well tolerated. The pain experience with operative Myosure was less than that reported during the diagnostic hysteroscopy by the same patient although this is unlikely of clinical significance. Importantly, Myosure was not more painful than the initial diagnostic procedure, and most patients were satisfied with the outcome and would choose to have the procedure again in an outpatient setting. This is in keeping with other studies which have shown a high degree of patient tolerance and satisfaction with this approach., Competing Interests: Declaration of competing interest The authors declare the following financial interests/personal relationships which may be considered as potential competing interests: Dr Samantha Mooney, Dr Lenore Ellett and Dr Emma Readman have completed paid consultancy work with Hologic.

Objective: Despite the high prevalence, mild traumatic brain injury (mTBI)-induced chronic headache and cognitive deficits are poorly understood and lack effective treatments. Low-dose interleukin-2 (LD-IL-2) treatment soon after mTBI or overexpressing IL-2 in brain astrocytes prior to injury protects mice from developing post-traumatic headache (PTH)-related behaviors and cognitive decline. The present study addresses a clinically relevant knowledge gap: whether LD-IL-2 treatment long after the initial injury is still effective for chronic PTH and cognitive deficits., Methods: mTBI was induced by a noninvasive closed-head weight drop method. LD-IL-2 was administered 4-6 weeks post-mTBI to assess its effects on chronic PTH-related facial mechanical hypersensitivity as well as mTBI-induced impairment in novel object recognition and object location tests. Endogenous regulatory T (Treg) cells were depleted to investigate the mechanism of action of LD-IL-2., Results: Delayed LD-IL-2 treatment abolished chronic PTH-related behaviors. It also completely reversed mTBI-induced cognitive impairment in both male and female mice. Treg cell depletion not only prolonged PTH-related behaviors but also abolished the effects of LD-IL-2. Interestingly, LD-IL-2 treatment significantly increased the number of Treg cells in dura but not in brain tissues., Interpretation: These results suggest that the beneficial effects of LD-IL-2 treatment are mediated through the expansion of meningeal Treg cells. Collectively, our study identifies Treg as a cellular target and LD-IL-2 as a promising therapy for both chronic PTH and mTBI-induced cognitive impairment for both males and females, with a wide therapeutic time window and the potential of reducing polypharmacy in mTBI treatment.

Objectives: To evaluate the efficacy of pain management of 1 ml of 24% sucrose given orally compared to routine care given one minute before vaccination for reduction of pain., Methods: This double-blind randomized controlled trial included term neonates visiting Pediatric OPD for immunization. Neonates were randomly assigned into two groups (Group A- Sucrose, Group B- Swaddling). Commercially available sucrose solution (StayHappi solution 24%) was given in a dose of 1 ml to the neonates. Video recording of the neonate's facial expression was done during the procedure. Duration of cry, latency of onset of cry as well Modified Neonatal Facial Coding Score (MFCS) were the outcome variables., Results: The mean (SD) of birth weight and gestational age was 2729 (321.6) g and 38.24 (0.84) d, respectively. Analysis showed significant difference in total MFCS across the groups (P <0.001). Total MFCS was significantly lower in sucrose group [4.88 (1.07) vs. 7.17 (0.95)]. The duration of cry (in seconds) was also found to be significantly lower in sucrose group., Conclusions: Administration of 1 ml 24% sucrose one minute prior to immunization is efficacious in pain management during injectable immunization., (© 2023.

Previous studies on pain experiences in retired contract sport athletes have been cross-sectional, leaving gaps in our understanding of the evolution of pain interference (PI) and factors that influence trajectories decades after sport discontinuation. This study investigated the longitudinal course of PI in former male National Football League (NFL) players over a 19-year period following sport discontinuation and examined factors influencing overall levels and trajectories of PI. Former NFL players completed health surveys in 2001, 2010, and 2019, with PI ratings measured using the 36-Item Short Form Health Survey (2001 and 2010) and the Patient-Reported Outcomes Measurement Information System (2019). Unconditional latent growth curve models analyzed overall PI severity and trajectories. Conditional latent growth curve models explored the influence of musculoskeletal injuries, osteoarthritis (OA), and depression diagnosis on PI. Over 19 years (N = 338; mean age = 48.96 ± 9.35), PI significantly increased (slope = .179, P < .001; mean Patient-Reported Outcomes Measurement Information System PI t-scores 2001 = 54.19, 2010 = 54.64, 2019 = 57.38). Cumulative musculoskeletal injuries (B = .092, P < .001) and baseline depression diagnosis (B = 4.463, P < .001) were associated with overall PI levels but not change over time. OA was significantly associated with overall PI levels (B = 6.536, P < .001) and trajectory (B = -.253, P < .001); those endorsing OA in 2001 had lower PI increases over 19 years. The body region of injury and level of play during injuries mirrored overall injury effects. PI mildly increased over 19 years, with multiple factors independently influencing overall PI levels. Enhancing former contact sport athletes' daily functionality may be achieved through holistic biopsychosocial interventions addressing musculoskeletal injuries, OA, and depression. Future research should identify factors influencing elevated trajectories of long-term PI post-sport discontinuation. PERSPECTIVE: This study assessed PI in former NFL athletes over 2 decades, revealing notable interindividual variability in trajectories over time. Musculoskeletal injuries, depression, and OA correlated with overall PI. Prevention and intervention in these 3 areas present the potential to improve disruptions in daily living due to pain in former athletes., Competing Interests: Disclosures This study (NFL-LONG) was funded by the National Football League (NFL).

While over 40 neonatal pain assessment scales have been published, owing to a lack of consensus and standardized metrics, there are more than 100 assessment indicators with varying descriptors and quality differences. This study aims to reach a consensus on optimal and comprehensive variables for neonatal pain assessment, leading to the development of a multidimensional neonatal pain response variable set. This study consisted of three phases: (1) A literature review was conducted to identify influencing factors and assessment indicators of neonatal pain response. (2) Panel meetings involving neonatal healthcare professionals evaluated and screened factors and indicators to develop an initial draft of the variable set. (3) Through two rounds of Delphi study achieved consensus, and determined the neonatal pain response variable set. Through a literature review and a panel meeting, the identified factors and indicators were categorized into contextual, physiological, and behavioral variables, forming an initial draft of the variable set. Sixteen professionals participated in two rounds of the Delphi study, with response rates exceeding 70%, and authority coefficients surpassing 0.7 in both rounds. The final iteration of the variable set includes 9 contextual variables, 2 physiological variables, and 5 behavioral variables.   Conclusion: Neonatal pain response variable set developed in this study is scientific, comprehensive, and multidimensional, aligning with the characteristics of neonatal pain response and clinically applicable. The inclusion of contextual variables enhances the ability to confront the complexity of clinical environments and individual differences. It can provide a practical and theoretical basis for clinical research on neonatal pain assessment. What is Known: • Neonatal pain assessment relies on scales used by healthcare professionals currently. But there is no "gold standard" for neonatal pain assessment. • While over 40 neonatal pain assessment scales have been published, owing to a lack of consensus and standardized metrics, there are more than 100 assessment indicators with varying descriptors and quality differences. Most of scales overlook the clinical environment complexity individual differences in pain responses, diminishing the accuracy and applicability. What is New: • In addition to the commonly used physiological and behavioral variables in the scales, we have incorporated contextual variables to better address the complexity of clinical environments and individual differences in pain responses. • Through an evidence-based approach, developed a neonatal pain response variable set comprising 9 contextual variables, 2 physiological variables, and 5 behavioral variables., (© 2024.

This population-based study investigated the prevalence of de novo, multitype, post-coronavirus disease (COVID) pain and its associated risk factors in previously hospitalized coronavirus disease 2019 (COVID-19) survivors. The nationwide, cross-sectional study included a cohort of Danish residents previously hospitalized due to severe acute respiratory syndrome coronavirus-2 infection between March 2020 and December 2021. Demographic data, preexisting medical comorbidities, previous pain-related symptoms, medication use for pain management, pain intensity (4-point scale), and development of de novo, multitype, post-COVID pain were collected by a self-reported survey distributed via e-Boks (a secured national digital mail system used in Denmark to provide public information to residents). The sample comprised 4,712 previously hospitalized COVID-19 survivors (48.6% women, mean age: 60.1 ± 15.6 years). At the time of the study (21 ± 6 months after hospitalization), 18.0% (847) reported the presence of de novo, multitype, post-COVID pain, and 38.6% of any pain. A multivariate analysis revealed that female sex (Odds Ratio (OR) 1.711, 95% Confidence Interval (CI) 1.444-2.023), higher body mass index (OR 1.032, 95% CI 1.019-1.045), intensive care unit admission (OR 1.597, 95% CI 1.324-1.926), previous history of whiplash (OR 2.471, 95% CI 1.004-6.081), anxiety (OR 3.626, 95% CI 1.335-9.708), and younger age (OR .982, 95% CI .976-.987) were factors associated with development of de novo, multitype, post-COVID pain. High income (OR .635, 95% CI .494-.817) and high educational level (OR .774, 95% CI .609-.984) were protective factors. In conclusion, multitype pain as a de novo post-COVID symptom was present in 18.0% of previously hospitalized COVID-19 survivors more than 1 year after hospital discharge and as such can be considered as adding to the global burden of chronic pain. PERSPECTIVE: The study investigates the prevalence of de novo, multitype, post-COVID pain in previously hospitalized COVID-19 survivors. This article presents potential risk factors associated with developing new pain symptoms. The results will contribute to understanding the possibility of predicting postinfectious pain from COVID-19 for future analysis., (Copyright © 2024 United States Association for the Study of Pain, Inc.

Background: Pain is routinely measured on mechanically ventilated ICU patients. However, the tools used are not designed to discriminate between pain and non-pain discomfort, a distinction with therapeutic implications., Objectives: To evaluate whether clinical measurement tools can discern both pain and non-pain discomfort., Methods: A prospective observational cohort study was conducted in a General ICU at a tertiary Medical Center in Israel. The Behavior Pain Scale (BPS) and Visual Analog Scale (VAS) of Discomfort were simultaneously assessed by a researcher and bedside nurse on thirteen lightly sedated patients during 71 routine nursing interventions in lightly sedated, mechanically ventilated, adult patients. Patients were asked whether they were in pain due to these interventions., Results: Statistically significant increases from baseline during interventions were observed [median change: 1.00 (-1-5), 1.5(-4-8.5), p < 0.001] as measured by BPS and VAS Discomfort Scale, respectively. BPS scores ranged between 4 and 6 when the majority (53 %) of the patients replied that they had no pain but were interpreted by the clinicians as discomfort. Endotracheal suctioning caused the greatest increase in BPS and VAS, with no statistically significant differences in BPS and VAS Discomfort Scale scores whether patients reported or did not report pain. A BPS>6 had a higher sensitivity and specificity to reported pain (accuracy of 76 %) compared to a BPS of 4-6., Conclusions: Standard assessments are sensitive to pain caused by routine nursing care interventions. However, this study presents evidence that among lightly sedated ICU patients, moderate BPS scores could also measure non-pain discomfort. ICU nurses should be aware that signs of unpleasantness measured by a pain scale could reflect non-pain discomfort., Competing Interests: Declaration of competing interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this manuscript, (Copyright © 2024.

Chemotherapy-induced peripheral neuropathy (CIPN) and associated pain are prevalent adverse effects of pediatric cancer treatment, significantly affecting the patient's quality of life. Their impact and risk factors have yet to be assessed in our country. This study aimed to assess the prevalence and clinical characteristics of CIPN, as well as to explore associations with patient- and treatment-related variables, within a cohort of Argentinean pediatric oncology patients. Sixty-six patients diagnosed with malignant hematopoietic tumors and receiving the neurotoxic agent vincristine were included in this observational study. Variables analyzed included age, gender, anthropometric measurements, tumor type, chemotherapy treatment, development of pain and other symptoms, severity, and analgesic treatment. The study population consisted of 39 boys and 27 girls. Most patients received two or three neurotoxic drugs. Symptoms consistent with CIPN were identified in 15 children, reflecting a prevalence of 23%. The main symptom was pain in the lower limbs, with some patients reporting jaw or generalized body pain. Pain was categorized as moderate or severe in 60% and 27% of cases, respectively. NSAIDs, anticonvulsants, and/or opioids were prescribed. Among the patient- and treatment-related variables analyzed as potential risk factors, the use of vincristine in conjunction with cytarabine and the administration of a higher number of neurotoxic drugs demonstrated significant association with the development of CIPN., Conclusions: Combination therapy stands out as a risk factor for clinical CIPN. The high prevalence of moderate/severe pain underscores the importance of close vigilance given its potential to compromise the patient's overall well-being., What Is Known: • Chemotherapy-induced peripheral neuropathy (CIPN) is a frequent adverse effect and dose-limiting factor in pediatric cancer treatment. • Prevalence varies among regions and risk factors are still under study., What Is New: • Prevalence of symptomatic CIPN is 23% among pediatric patients undergoing treatment for hematopoietic tumors in a referral hospital in Argentina. Most patients report moderate or severe pain. • Combining vincristine with cytarabine and using a higher number of neurotoxic drugs in combination therapies exhibit significant association with the development of CIPN-related symptoms., (© 2024.

Objective: To examine the moderation effects of daily behavior on the associations between symptoms and social participation outcomes after burn injury., Design: A 6-month prospective cohort study., Setting: Community., Participants: Twenty-four adult burn survivors., Interventions: Not applicable., Main Outcome Measures: Symptoms and social participation outcomes were assessed weekly using smartphone surveys, including symptoms of pain (Patient-Reported Outcomes Measurement Information System [PROMIS] Pain Intensity and Pain Interference), anxiety (PROMIS Anxiety), and depression (Patient Health Questionnaire), as well as outcomes of social interactions and social activities (Life Impact Burn Recovery Evaluation [LIBRE] Social Interactions and Social Activities). Daily behaviors were automatically recorded by a smartphone application and smartphone logs, including physical activity (steps, travel miles, and activity minutes), sleep (sleep hours), and social contact (number of phone calls and message contacts)., Results: Multilevel models controlling for demographic and burn injury variables examined the associations between symptoms and social participation outcomes and the moderation effects of daily behaviors. Lower (worse) LIBRE Social Interactions and LIBRE Social Activities scores were significantly associated with higher (worse) PROMIS Pain Intensity, PROMIS Pain Interference, PROMIS Anxiety, and Patient Health Questionnaire-8 scores (P<.05). Additionally, daily steps and activity minutes were associated with LIBRE Social Interactions and LIBRE Social Activities (P<.05), and significantly moderated the association between PROMIS Anxiety and LIBRE Social Activities (P<.001)., Conclusions: Social participation outcomes are associated with pain, anxiety, and depression symptoms after burn injury, and are buffered by daily physical activity. Future intervention studies should examine physical activity promotion to improve social recovery after burns., (Copyright © 2024 American Congress of Rehabilitation Medicine.

Objectives: To study whether poor sleep and comorbidities are associated with high symptom levels of patient-reported outcomes (PROs) pain, patient global assessment and fatigue in patients with rheumatoid arthritis (RA) and psoriatic arthritis (PsA), in a nation-wide cross-sectional setting., Methods: Clinical data were extracted from The Finnish Rheumatology Quality Register between 1.2021 and 9.2022. Self-reported sleep was categorized as "good" (little/no difficulties) or "poor" (great difficulties/can't) sleep. Data concerning comorbidities were collected from national registers. Descriptive statistics were used. Regression analyses were applied to analyze independent associations of sleep status, comorbidities and disease activity with pain in RA and PsA, adjusting for age and sex., Results: Among 13,512 patients with RA, 6052 [mean (SD) age 62 (13), 71% female] had sleep status reported; in PsA 1861/3636 [age 55 (13), 48% female]. In RA, 5072 (84%) reported good and 980 (16%) poor sleep; the corresponding numbers in PsA were 1460 (78%) and 401 (22%). Median values for objective disease activity were low and similar in patients with poor sleep and good sleep in both diseases. Among patients with no swollen joints, the median values for PROs were approximately three times higher for patients with poor sleep vs. good sleep in both diagnoses (P<0.001). In regression analyses, "poor" sleep was independently associated with higher symptoms in pain [B (95%CI) 20 (18,22) in RA and 23 (19, 26) in PsA], followed by comorbid fibromyalgia, as well as depression in RA and sleep apnea in PsA., Conclusion: "Poor" sleep quality and comorbidities are independently associated with pain. Patient's sleep status is important to know especially in patients with severe symptoms without objective disease activity., (Copyright © 2024 The Author(s). Published by Elsevier Masson SAS..

Purpose: In correlation with magnetic resonance imaging (MRI), this study attempts to assess the effectiveness of the diagnostic of ultrasonography (US) features and shear wave elastography (SWE) in determining the different causes of heel pain., Materials and Methods: 55 heels with a mean age of 38.33 ± 10.8 were included in the study (10 control cases and 41 cases, 4 of which had bilateral heel pain). There were 23 female cases (56.1%) and 18 male cases (43.95%). Examinations using shear wave elastography (SWE) and ultrasound (US) were done in different positions. MRI and the obtained data were correlated., Results: When used to diagnose different heel pain causes, ultrasound demonstrated great sensitivity and specificity. SWE demonstrated a good correlation with MRI findings and enhanced the ultrasound's diagnostic precision in identifying plantar fasciitis early on (increased accuracy from 88.9 to 93.33% with 100% sensitivity and 83.3% specificity) and Achilles tendinopathy (increased accuracy from 88.9 to 97.8 with 94.7% sensitivity and 100% specificity)., Conclusion: In summary, we concluded that heel pain can be efficiently examined by both ultrasound (US) and shear wave elastography (SWE) with the former being used as the primary effective tool and the latter being done to increase diagnostic accuracy. We also concluded that SWE improved the ultrasound's diagnostic precision in identifying patients with early plantar fasciitis and Achilles tendinopathy and showed a robust relationship with clinical outcomes, enhancing patient evaluation and follow-up., (© 2024.
