Complications after primary and revision shoulder arthroplasty: a matched cohort study

BackgroundPatients who undergo total shoulder arthroplasty typically have excellent clinical outcomes, though some patients require revision shoulder arthroplasty to address complications such as infection, instability, and persistent pain. The purpose of this study was to compare the rates and types of complications, as well as patient-reported outcomes, following primary and revision shoulder arthroplasty. MethodsRetrospective chart review was conducted for patients who underwent revision anatomic or reverse shoulder arthroplasty between January 2015 and May 2021 (N = 152). A cohort of patients who underwent primary shoulder arthroplasty in the same period was generated by matching 1:1 for implant type (anatomic/reverse), age, and surgery date. Demographic data, patient-reported outcomes, surgical details, surgical complications, and reoperations were collected for both cohorts (N = 304). Chi-square, t-test, Fisher’s exact test, and Mann-Whitney test were used as appropriate. ResultsThe revision cohort had a significantly higher rate of surgical complications than the primary cohort (N = 58, 38.2% vs. N = 22, 14.5%; P < .0001). The distribution of complication types differed significantly between the primary and revision cohorts (P = .018). Revision patients reported less improvement in Single-Assessment Numeric Evaluation score from baseline to 2-year follow-up compared to primary patients (postoperative and preoperative scores 33.9 ± 35.9 vs. 52.3 ± 32.5; P = .036). Patients in the primary cohort who underwent a previous shoulder surgery before their shoulder arthroplasty were more likely to experience complications than those who did not (P < .001). The most common surgical complications in the revision cohort were persistent pain (N = 20) and periprosthetic joint infection (N = 10), while the most common complications in the primary cohort were persistent pain (N = 6) and instability (N = 4). 63.6% of complications in primary patients and 55.2% of complications in revision patients necessitated reoperation. Total procedure time was higher on average in revision patients (120 ± 68 min) than primary patients (94 ± 31 min; P < .0001). Revision patients were more likely than primary patients to have had cemented humeral stems in their primary arthroplasty (P = .043). ConclusionPatients undergoing revision shoulder arthroplasty are at an increased risk for subsequent surgical complications and worse clinical improvement compared to primary shoulder arthroplasty patients. The differing profiles of postoperative complication types following primary and revision shoulder arthroplasty should be considered when advising patients on the risks of surgery and creating preoperative surgical plans to minimize these risks.

Matching males and females undergoing non mesh primary unilateral inguinal hernia repair: evaluating sex differences in preoperative and acute postoperative pain.

The objective was to compare pain and related psychological factors during the preoperative and acute postoperative period between male and female patients, who underwent non mesh primary unilateral inguinal hernia repair. After ethics approval, informed consent was obtained, and data were collected. Male and female participants were compared by manually matching one-to-one on 10 variables. Descriptive statistics (mean ± standard deviation and frequency) as well as numerical rating scales from 0 to 10 were used. Comparison tests were performed using Chi-square or Fisher's Exact test for categorical data and independent samples t-test or non-parametric equivalent tests for numerical scores. p < 0.05 is reported as statistically significant. To control type I error, Bonferroni correction was used. 72 participants with 36 matched pairs were included. Sex differences were found for operation length (p = .006), side of operation (p = .002), and hernia type (p = .013). Significant differences between the sexes were not found at the preoperative or postoperative time for resilience, pain interference or pain severity related measures, postoperative hernia pain incidence, pain catastrophizing, depression and anxiety symptoms, or return to normal activities. When controlling for known confounders and using a conservative Type I error rate, pain and related factors between the sexes did not differ significantly.

Exploratory pharmacodynamics and efficacy of PF-06817024 in a Phase 1 study of patients with chronic rhinosinusitis and atopic dermatitis

PF-06817024 is a humanized antibody against interleukin-33 that has the potential to inhibit type 2 inflammation. An exploratory analysis of the pharmacodynamics and clinical effects of single and repeat doses of PF-06817024 was assessed in patients with chronic rhinosinusitis with nasal polyps (CRSwNP) and patients with moderate-to-severe atopic dermatitis (AD), respectively, as part of a Phase 1, first-in-human study. Rhinosinusitis symptoms were improved, and nasal polyps were decreased in size following treatment with PF-06817024 in patients with CRSwNP. In patients with AD, PF-06817024, in aggregate, reduced disease severity and improved symptoms, as demonstrated by greater percentage decrease from baseline in Eczema Area and Severity Index (EASI) scores and reduced pruritus numerical rating scores, compared with placebo. The efficacy in AD appeared to be bimodal with a sub-group of participants exhibiting high levels of improvement (EASI75 and EASI90) for a sustained period of time after dosing. In patients with CRSwNP, a consistent trend of decrease in eosinophil levels was observed in the PF-06817024 group, compared with placebo. Further research would be needed to confirm the clinical benefit and safety of PF-06817024 as a treatment for allergic diseases.Trial registration ClinicalTrials.gov, NCT02743871.

Thick-shell sulcus-deepening trochleoplasty for recurrent patellar dislocation leads to clinically meaningful improvements and high patient satisfaction in adolescents with open physes

ObjectivesTo evaluate clinical and radiological outcomes of thick-shell, sulcus-deepening trochleoplasty in patients with open distal femoral physes and less than two years of growth remaining. We hypothesized that patients would have clinical and radiographic improvements in addition to high patient-reported outcomes following thick-shell, sulcus-deepening trochleoplasty. MethodsBone age was determined on preoperative magnetic resonance imaging (MRI) using the Pennock Knee Bone Age Atlas. Pre- and postoperative radiographs were used to measure the anatomic lateral distal femoral angle (aLDFA) and Blumensaat angle. International Knee Documentation Committee (IKDC), Kujala, and numerical patient satisfaction scores were assessed. Pre- and postoperative aLDFA and Blumensaat angles as well as patient-reported outcomes were analyzed via the Wilcoxon signed-rank test. ResultsSeventeen adolescents (21 knees) with DeJour Types B and D trochlear dysplasia and open distal femoral physes underwent Dejour thick-shell, sulcus-deepening trochleoplasty at a single institution. In twelve females (16 knees, 76.2%) the median chronological and bone ages at the time of operation were 14.9 and 14.3 years, respectively. In 5 males (5 knees, 27.7%), the median chronological and bone ages at the time of operation were 15.7 and 15.2 years, respectively. Mean follow-up time was 64 months postoperatively. Physes were closed in all knees at the time of final clinical and radiographic follow-up. The mean change in aLDFA and Blumensaat Angle was 0.73 (p ​= ​0.1074, 95% CI -0.09–1.57) and 0.88° (p ​= ​0.0477, 95% CI 0.10–1.88), respectively. Median IKDC scores improved from 57.3 preoperatively to 90.9 postoperatively, for a mean difference of 26.1 (p ​= ​0.00064, 95% CI 18.0–34.2). Median Kujala scores improved from 55.0 preoperatively to 95.0 postoperatively, for a mean change of 30.2 (p ​= ​0.0008, 95% CI 19.6–40.8). Overall mean numerical patient satisfaction was high (mean 9.26/10). One of 21 knees (4.8%) underwent additional surgery to address recurrent patellar instability. ConclusionThick-shell sulcus-deepening trochleoplasty for addressing recurrent lateral patellar instability in patients with open distal femoral physes and less than two years of growth remaining is safe and provides clinically meaningful improvements in addition to high patient satisfaction when combined with other patellar stabilization procedures.

Comparative analysis of four upper gastrointestinal bleeding scoring systems for predicting multiple outcomes: an observational study in the emergency department

Objective: Numerous scoring systems have been developed to assess the risk associated with upper gastrointestinal bleeding (UGIB), and several studies have investigated their comparative accuracy in predicting patient outcomes. This study was undertaken to compare four well-known scoring systems, namely the pre-endoscopy Rockall score, full Rockall score, Glasgow-Blatchford Bleeding score (GBS), and AIMS65, with the aim of predicting five distinct outcomes in cases of non-variceal UGIB. Methods: This prospective observational study was conducted focusing on adult patients with UGIB presenting to the emergency department (ED). The primary endpoints of this study included in-hospital mortality, the need for re-endoscopy, the requirements for packed red blood cell (PRBC) transfusion, massive transfusion, and one-month rebleeding. Results: A total number of 320 patients were enrolled, with 44 (13·75%) in-hospital deaths. Based on the area under the curves (AUC), while certain scores outperformed others in specific outcome prediction, the AIMS65 scoring system demonstrated superior predictive capability for both in-hospital mortality (0.91) and massive transfusion (0.71). Regarding PRBC transfusion requirements, both AIMS65 and GBS exhibited similar predictive capacities (AUC=0.67 and 0.68, respectively). In terms of re-endoscopy and one-month rebleeding, the GBS scoring system displayed slightly better performance compared to the other systems (AUC=0.61 and 0.63, respectively). In the composite outcome, all scores had significant associations, and among them, the AIMS-65 score had the highest AUC (0.76). Conclusion: The AIMS65 scoring system was the most reliable tool for predicting in-hospital mortality and, to a lesser extent, massive transfusion requirements, while GBS and AIMS65 could be moderately and cautiously relied on for preparations regarding the need for PRBC transfusion.

Cryo-Pneumatic Compression Results in a Significant Decrease in Opioid Consumption After Shoulder Surgery: A Multicenter Randomized Controlled Trial.

The management of pain after shoulder surgery typically includes the use of cryotherapy and the prescription of opioid analgesics. Much focus has been placed lately on the opioid epidemic, which in part is fueled by excessive prescription of opioid medication. Previous studies have found a combination of cryotherapy and compression effective at reducing analgesic consumption and increasing recovery in patients undergoing knee and spine surgery; however, efficacy in patients undergoing shoulder surgery has not been evaluated. To evaluate the effectiveness of a cryo-pneumatic compression device on postoperative shoulder pain, narcotic use, and quality of life when compared with standard care cryotherapy. Randomized controlled trial; Level of evidence, 2. In total, 200 patients older than 18 years scheduled for unilateral shoulder surgery were enrolled. Patients were randomized to receive either postoperative cryo-pneumatic compression or standard care. The intervention group received a cryo-pneumatic device, while the standard care group received the treating surgeon's preferred method of postoperative care, including standard cryotherapy. Narcotic use was evaluated by the number of oral morphine milligram equivalents consumed during the postoperative period, as well as the time to cessation of narcotic use. Patient-reported outcome measures consisted of a numeric rating scale pain score, 36-item Short Form Survey, patient experience assessed using the net promoter score, and adverse events. Outcomes were evaluated at 2, 6, and 12 weeks postoperatively. Patients receiving cryo-pneumatic compression reported a significant decrease in opioid consumption when compared with standard care (oral morphine milligram equivalents median, 56.1 vs 112; P = .02468). A significant increase in self-reported function was seen in the cryo-pneumatic compression group at 2 weeks when compared with standard care (mean, 61.2 vs 54.2; P = .0412). In patients undergoing unilateral shoulder surgery, the use of cryotherapy with pneumatic compression, when compared with standard care, resulted in significantly decreased opioid consumption as well as increased function at 2 weeks.

Based on these findings, it can be inferred that utilising drill and game techniques can enhance the educational achievements in passing content for VB class students at SDN Putat Gede 1/94 Surabaya.

Real-world evidence evaluation on consumer experience and prescription journey of diclofenac gel in Sweden.

The aim of this study was to understand profiles of topical Voltaren gel diclofenac (VGD) 2.32 and 1.16% consumers through analyzing prescription patterns and to characterize treatment satisfaction, functional impairment, and pain relief after over-the-counter (OTC) VGD use in Sweden under real-world conditions. This observational, real-world study conducted in Sweden had retrospective and prospective segments. The retrospective secondary data segment utilized 12-month diclofenac gel prescription data from the Swedish eHealth Agency (E-hälsomyndigheten). The prospective segment included electronic surveys completed at baseline and weeks 4 and 12 by adult consumers who purchased OTC VGD to treat their pain. Secondary data analyses (n = 12,145) showed that 56.7% of patients receiving diclofenac gel were females ≥70 years old. Most patients did not switch pain treatments; the mean time between diclofenac gel refills was about 2.5 months. From the surveys (n = 264), VGD provided pain relief, indicated by improvement in 11-point pain numeric rating scale scores. Average pain severity at baseline was 5.8 - improving by a mean of 1.3 and 1.9 points at weeks 4 and 12, respectively. The majority of consumers reported improvement in daily functioning (i.e., health-related quality of life [HRQoL]), and most were at least somewhat satisfied with VGD treatment results. This real-world study provides important insights into the prescription patterns of diclofenac gel and the consumer experience with OTC VGD in Sweden. Patients rarely switched to other topical nonsteroidal anti-inflammatory drugs, and VGD consumers reported pain relief and improved HRQoL compared to baseline - resulting in treatment satisfaction.

A machine learning-based simulation metamodeling method for dynamic scheduling in smart manufacturing systems

Conventional Digital Twins (DTs) in smart manufacturing rely on complex and time-intensive simulation models, hindering real-time DT-based decision-making. However, the availability of big data in Manufacturing Execution Systems (MES) enables training different Machine Learning (ML) models for fast and accurate predictions and decision assessments. Accordingly, this paper proposes an ML-Based Simulation Metamodeling Method (MLBSM) to facilitate DT-based decision-making for dynamic production scheduling in complex Stochastic Flexible Job Shop (SFJS) environments. The proposed MLBSM integrates three modules: a novel data vectorizing method (SPBM), multi-output Adaptive Boosting Regressor (ABR) models, and a new statistical risk evaluation method. SPBM converts unstructured production log data into numerical vectors for ABR training by calculating numeric penalty scores for each job based on the position of operations in the schedule queue. Each trained ABR predicts mean job completion times for various dynamic scenarios based on shift schedules. The risk evaluation method estimates the standard deviation of job completion times and calculates the delay probability scores for each job, aiding DT in promptly evaluating production schedules. Working seamlessly together, MLBSM modules present a novel way of using production log data for ML training and ultimately bypassing several computationally intensive simulation replications. In this research, a simulation model generates the synthetic MES data, focusing on the machining process at a photolithography workstation in the semiconductor manufacturing. Experiments demonstrate the MLBSM’s accuracy and efficiency, predicting high-risk jobs with over 80% recall and being at least 70 times faster than conventional simulation runs. Sensitivity analyses also confirm the MLBSM’s consistency under different workstation conditions.

Australian adaptation and external validation of Commissioning for Quality in Rheumatoid Arthritis-RA-Patient Reported Experience Measure (CQRA-RA-PREM).

To evaluate the reliability and validity of an adapted Commissioning for Quality in Rheumatoid Arthritis-RA-Patient-Reported Experience Measure (CQRA-RA-PREM) for assessing care experience in an Australian rheumatology outpatient cohort. Individual patient interviews were performed to check the language and completion time of the CQRA-RA-PREM before modification. Australian Rheumatology Association Database (ARAD) participants completed the CQRA-PREM-Australian version (CQRA-PREM-AU) (22 items, 5 domains), disease activity measure (RAPID-3, BASDAI) and Assessment of Quality of Life (AQOL-6D) index. Exploratory factor analysis (EFA) assessed item correlation. Cronbach's α assessed internal consistency. Individual patient interviews (n = 8, 62% male, mean age 50 years, mean disease duration 4.5 years) informed CQRA-RA-PREM modification. The ARAD survey response rate was 707/1124 (63%); 459 (65%) RA, 134 (19%) PsA, 114 (16%) AS; 67% female, mean age 62 years, mean disease duration 22 years. The median instrument completion time was 299 s (interquartile range 284-414). Scoring of responses allowed an averaged overall score. EFA extracted five factors: all items loading similarly onto factor 1, indicating validity of the overall score. The CQRA-PREM-AU score correlated with the AQOL-6D score (ρ = 0.23, P < 0.01); partial correlation with disease activity was not significant (ρ = 0.03, P = 0.45), indicating divergent validity. Reliability was comparable across disease subgroups (Cronbach's α >0.94). The mean overall score did not differ by disease subgroup [4.1 (s.d. 0.6, P = 0.73) and there was no floor/ceiling effect. CQRA-PREM-AU is a valid and reliable instrument to measure self-reported care experience in Australian rheumatology patients and may be interpreted as an average overall numerical score.

Claudin-2: A marker for a better evaluation of histological mucosal healing in inflammatory bowel diseases

BackgroundHistological mucosal healing has become a paramount target goal to achieve in the treatment of inflammatory bowel diseases. However, there is still a lack of agreement on the best way to reach this goal, since numerous histological scores are available worldwide. AimsWe investigated whether claudin-2, a member of claudin family involved in the regulation of intestinal tight junctions, might be useful to assess the presence of active disease in patients with inflammatory bowel diseases. MethodsBiopsies from 123 patients with ulcerative colitis, Crohn's disease, infectious colitides and irritable bowel syndrome patients where tested with immunohistochemistry for claudin-2. ResultsClaudin-2 appeared to be a very sensitive marker of disease activity in inflammatory bowel diseases, but was negative in the other kinds of patients. In addition, immunohistochemistry for claudin-2 showed good reproducibility by different pathologists. ConclusionsShould these findings be confirmed in more numerous cohorts of patients, and especially in those with minimal or focal residual disease activity, this simple assessment could be useful in the routine daily practice to facilitate the task of pathologists and clinicians in the diagnosis and management of patients with inflammatory bowel diseases.

Response processes for patients providing quantitative self-report data: a qualitative study.

To identify factors that influence response processes for patients providing quantitative self-report data. Secondly, due to the lack of integrative and explanatory models in this area, to develop a model of patients' response processes that can guide what to look for when considering validity evidence and interpreting scores on individual items. Participants (n = 13) were recruited from a specialized substance use disorder treatment clinic and interviewed while responding to items from a clinical feedback system implemented for routine outcome monitoring in that setting. The interview approach was based on cognitive interviewing. Data collection and analysis were inspired by a grounded theory approach. We identified several variables that influenced the participants' response processes. The variables were organized into five categories: context-related variables; item-related variables; response base variables; reasoning strategies; and response selection strategies. We also found that the participants' responses for many items were affected by different aspects of the response process in ways that are relevant to interpretation but not necessarily discernible from the numerical scores alone, and we developed response categories to capture this. The findings suggest that patients providing quantitative self-report data encounter conditions in the response process that challenge and influence their ability to convey meaning and accuracy. This results in responses that for many of the items reflect messages important for interpretation and follow-up, even if it does not appear from the numerical scores alone. The proposed model may be a useful tool when developing items, assessing validity, and interpreting responses.

The prevalence and predictors of discharge opioid overprescribing in opioid-naïve patients after breast, gynecologic, and head and neck cancer surgery: a prospective cohort study.

The management of pain following cancer-related surgeries involves the use of opioid analgesics. Nevertheless, there is little evidence characterizing the utility and prescription patterns of opioids after these procedures. Our primary aim was to identify patients from three types of cancer surgery who were overprescribed with opioids. The secondary aim was to determine the potential predictors of overprescribing in the same period. We conducted the study at a single cancer referral hospital. Opioid-naïve patients with breast, gynecologic, or head and neck cancer were studied. Patients were considered opioid-naïve if they had a history of opioid use ≤ 30mg oral morphine equivalent daily dose for less than seven days in the preceding three months before surgery. We recruited eligible participants by convenience sampling on the wards until at least 102 patients were included in the final analysis. After discharge, we followed up on the participants on day 7 via telephone using a structured proforma including questions to identify the last date and amount of opioid dose taken. The equivalent days of opioid use were calculated by their 24-hr use before discharge and the number of doses prescribed for discharge. Our primary outcome was the prevalence of overprescribing in the three surgical specialties defined as the number of patients taking less than 50% of discharge opioids within the first seven days after discharge. We examined the predictors on incidents of overprescribing using multivariable Poisson regression as the secondary outcome. We recruited 119 patients, and 107 patients were included in the final analysis. There were 59/107 (55%) patients found to be overprescribed with opioids. At discharge, they exhibited lower mean numerical rating scale pain scores, lower mean pain severity scores, higher equivalent days of opioids prescribed, and not used opioids in the last 24hr before discharge. The incidence of overprescribing was 2.4 times greater for patients prescribed with opioids without 24-hr opioid use (relative risk [RR], 2.38; 95% confidence interval [CI], 1.30 to 4.35; P = 0.005). Similarly, the incidence of overprescribing was 1.7 times greater for patients who had opioids 24hr before discharge and were supplied with opioids for five equivalent days or more at the time of discharge (RR, 1.67; 95% CI, 1.09 to 2.56; P = 0.02). Our study shows that the majority of recruited patients undergoing breast, gynecologic, or head and neck cancer surgery were overprescribed opioids. Individualized assessments on patients' 24-hr opioid requirements before discharge and supplying for less than five days are important considerations to reduce overprescribing in opioid-naïve patients after cancer surgery.

Association Between Non-spinal Comorbid Medical Conditions and Neuropathic Low Back Pain. - A Further Unravelling of Pain Complexities in the Context of Back Pain.

Prospective cohort study. Understanding the complex nature of low back pain (LBP) is crucial for effective management. The PainDETECT questionnaire is a tool that distinguishes between neuropathic (NeP) and nociceptive (NoP) low back pain. Traditionally NeP and NoP have been primarily attributed to patho-anatomical abnormalities within the lumbar spine. However, increasing evidence points to multifaceted involvement, encompassing a range of physical, biomechanical, chemical, and psychosocial factors. The study aimed to determine the independent relationship between NeP as assessed by the PainDETECT questionnaire and non-spinal comorbid medical conditions. A prospective cohort study was conducted involving 400 patients suffering from chronic LBP (>6months), aged >18years, who complete the PainDETECT questionnaire and provided responses regarding the presence of any comorbid conditions. A binary logistic regression model was used to analyse the confounding status of comorbid medical conditions and pain severity measured by NRS to determine independent relationships between specific conditions and neuropathic pain. The study included 143 and 257 patients suffering from NeP and NoP, respectively. The NeP group had a 38% higher mean numerical rating scale score compared to the NoP group (8.10 1.55 vs 5.86 2.26, P < 0.001). The odds of developing NeP were 2.9 Exp(B) = 2.844, 95%C.I. [1.426-5.670], P < 0.01), 2.7 (Exp(B) = 2.726, 95%C.I. [1.183-6.283], P < 0.05) and 2.8 (Exp(B) = 2.847, 95%C.I. [1.473-5.503], P < 0.05) times higher in patients suffering from gastrointestinal conditions, rheumatoid arthritis, and depression, respectively. NeP as determined by the PainDETECT questionnaire, is associated with gastrointestinal conditions, rheumatoid arthritis, and depression. This pioneering study has shed light on the potential involvement of the gut microbiome as a common factor connecting non-spinal comorbidities and NeP. These findings underscore the importance of formulating personalized management plans tailored to individual pain and medical profiles, rather than relying on a blanket approach to pain management.

Integrative Korean medicine treatment for inpatients with osteoarthritis of the knee: An observational study.

The use of integrative Korean medicine treatment (IKMT) for patients with knee osteoarthritis (OA) has been reported previously; however, to date, no studies have investigated the long-term prognosis of these patients following IKMT for primary knee OA. We aimed to examine the long-term effects of IKMT in patients diagnosed with primary knee OA and receiving IKMT during hospitalization. This retrospective observational study, complemented by a follow-up survey, included patients with primary knee OA who received IKMT during hospitalization across 7 Korean medicine hospitals. The primary outcome was the Numerical Rating Scale knee-pain score, whereas the secondary outcomes were the Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC), EuroQol-5 dimension-5 level questionnaire (EQ-5D-5L), and Patient Global Impression of Change scores. Patients were evaluated at admission, discharge, and during follow-up. Of the 180 included patients, 81 responded to the survey. Compared with the corresponding values at admission, the Numerical Rating Scale score decreased by 2.44 (2.08-2.81) points at discharge and 1.89 (1.5-2.26) points at follow-up. Additionally, compared with their scores at admission, the WOMAC score decreased by 17.20 (13.68-20.71) points at discharge and 25.74 (22.22-29.26) points at follow-up, whereas the EuroQol-5 dimension-5 level questionnaire score improved by -0.15 (-0.18 to -0.12) points at discharge and -0.12 (-0.15 to -0.09) points at follow-up. The patients expressed high satisfaction with pharmacopuncture (65.4%), acupuncture (54.03%), physical therapy (35.8%), and herbal medicine (34.6%). Regarding Patient Global Impression of Change, 96.30% of the patients reported improvement. IKMT was effective in improving pain, functional disability, and quality of life in patients with primary knee OA. Its effects were maintained throughout the long-term follow-up period, and physical functions continuously improved.

Insomnia among patients with chronic pain: A retrospective study.

Insomnia can coexist with chronic pain and is a major cause of rapidly increasing medical expenses. However, insomnia has not been fully evaluated in patients with chronic pain. This retrospective study aimed to identify the risk factors for insomnia in patients with chronic non-cancer pain. A total of 301 patients with chronic non-cancer pain were enrolled. Patients with the Athens insomnia scale scores ≥ 6 and < 6 were classified into insomnia (+) and insomnia (-) groups, respectively. All patients completed self-report questionnaires as part of their chronic pain treatment approach. Univariate and multivariate analyses were performed to predict insomnia. We found that 219 of 301 (72.8%) patients met the AIS criteria for insomnia. Significant differences were depicted between patients with and without insomnia in terms of body mass index, numeric rating scale, pain catastrophizing scale, hospital anxiety, and depression scale (HADS), pain disability assessment scale, EuroQol 5 dimension (EQ5D), and pain self-efficacy questionnaire. Multiple regression analysis identified the numeric rating scale, HADS, and EQ5D scores as factors related to insomnia in patients with chronic non-cancer pain. Anxiety, depression, and disability were associated with a greater tendency toward insomnia. HADS and EQ5D scores are useful screening tools for preventing insomnia in patients with chronic non-cancer pain.

This case series evaluates changes in numeric pain scores, opioid use, and other measures before, during, and 30 days after computed tomography–guided percutaneous cryoneurolysis in patients with rib injury.

Comparison of the preclinical quality of analgesia of emergency physicians and paramedics based on trauma patients

Adequate prehospital pain management is acritical component of emergency medical services. With the introduction of the paramedic profession and the Paramedics Act in Germany, the basis for more extensive competencies of paramedics was established. In many emergency medical service areas it is thus possible for paramedics to perform analgesia and sedation with esketamine/midazolam according to pre-established instructions and/or standard operating procedures. This study assessed the quality of analgesia administered to trauma patients by paramedics compared to emergency medical service physicians. The study included trauma patients who received prehospital administration of analgesia by either emergency medical service physicians or paramedics and were subsequently admitted to the central emergency department of the Saarland University Hospital. Astandardized data collection form was used to collect information from the emergency service protocol and initial emergency department assessment. The evaluation employed descriptive statistical methods and a total of 207 completed records were analyzed. Both professional groups achieved significant pain reduction and fulfilled the criteria for effective pain management (pain reduction: emergency medical service physicians 5.5 ± 2.0/paramedic 4.4 ± 2.1, p < 0.001). Emergency medical service physicians, however, more frequently attained ahigher reduction in numerical rating scale scores and administered oxygen. Notable differences were observed in the range of medications used and the dosages. This study could show that prehospital analgesia is comparable between emergency medical service physicians and paramedics in terms of effectiveness for trauma patients if the indications are correctly set, while observing pre-existing instructions. With their competencies paramedics are able to perform an effective and safe analgesic treatment within the framework of preformulated procedural instructions, which can be equal to that of an emergency medical service physician.

Low molecular weight 35 kDa hyaluronan fragment HA35 in the treatment of bone metastasis pain: A case report.

Late-stage cancer patients often experience severe pain due to bone metastasis, caused by structural damage and cancer-induced inflammation. Hyaluronan, known to alleviate pain by blocking the TRVP1 calcium channel, faces limitations due to its high molecular weight. However, 35 kDa low molecular weight hyaluronan fragment (HA35) have shown promise in relieving various pains, including cancer-related pain. Nonetheless, evidence regarding their efficacy in bone metastasis pain remains scarce. A 52-year-old female with a rectal malignant tumor and multiple secondary tumors in the sacrum and lungs, accompanied by bone metastasis pain. Despite undergoing radiotherapy, her pain relief was unsatisfactory. Before treatment with HA35, her numerical rating scale score was 10, severely affecting her sleep, appetite, and daily activities. The patient was diagnosed with rectal malignant tumor with multiple metastases, presenting symptoms such as sacral metastasis pain, anal pain, lower limb pain, and anterior abdominal pain. Sacral metastasis pain and lower limb pain indicated a clear diagnosis of bone metastasis pain. Treatment involved subcutaneous injection into the deep fat tissue layer of the abdomen. A subcutaneous injection of 100 mg/5 mL of HA35 was administered once into the deep fat tissue of the abdomen, with subsequent injections repeated every 3 days. Following 1 injection, the patient's pain score decreased to 6 points within 20 minutes, providing 40% pain relief. After 40 minutes, the score further dropped to 4 points, with 60% pain relief. After 50 injections, pain was consistently controlled at around 3 points. Subcutaneous injection of HA35 into the abdominal fat tissue effectively alleviates pain in cancer and bone metastasis patients resistant to conventional treatments. Additionally, it helps alleviate anxiety and fatigue, and improves diet and sleep, thereby offering crucial palliative care for advanced cancer patients.

Single session and repeated anodal transcranial direct current stimulation over the right dorsolateral prefrontal cortex increases reflective thinking but not working memory updating performance

BackgroundAnodal transcranial direct current stimulation (tDCS) over the right dorsolateral prefrontal cortex (DLPFC) has shown to have effects on different domains of cognition yet there is a gap in the literature regarding effects on reflective thinking performance. ObjectiveThe current study investigated if single session and repeated anodal tDCS over the right DLPFC induces effects on judgment and decision-making performance and whether these are linked to working memory (updating) performance or cognitive inhibition. MethodsParticipants received anodal tDCS over the right DLPFC once (plus sham tDCS in a second session) or twice (24 h apart). In the third group participants received a single session of sham stimulation only. Cognitive characteristic measures were administered pre-stimulation (thinking disposition, impulsivity, cognitive ability). Experimental tasks included two versions of the Cognitive Reflection Test (numeric vs verbal-CRT), a set of incongruent base-rate vignettes, and two working memory tests (Sternberg task and n-back task). Forty-eight participants (mean age = 26.08 ± 0.54 years; 27 females) were recruited. ResultsSingle sessions of tDCS were associated with an increase in reflective thinking performance compared to the sham conditions, with stimulation improving scores on incongruent base rate tasks as well as marginally improving numeric CRT scores (compared to sham), but not thinking tasks without a numeric component (verbal-CRT). Repeated anodal stimulation only improved numeric CRT scores. tDCS did not increase working memory (updating) performance. These findings could not be explained by a practice effect or a priori differences in cognitive characteristics or impulsivity across the experimental groups. ConclusionThe current results demonstrate the involvement of the right DLPFC in reflective thinking performance which cannot be explained by working memory (updating) performance or general cognitive characteristics of participants.
