Chronic thoracic pain after cardiac surgery: role of inflammation and biomechanical sternal stability.

The pathogenesis of chronic chest pain after cardiac surgery has not been determinate. If left untreated, postoperative sternal pain reduces the quality of life and patient satisfaction with cardiac surgery. The purpose of the study was to examine the effect of chest inflammation on postoperative pain, risk factors for chronic pain after cardiac surgery and to explore how chest reconstruction was associated with the intensity of pain. The authors performed a study of acute and chronic thoracic pain after cardiac surgery in patients with and without sternal infection and compared different techniques for chest reconstruction. 42 high-risk patients for the development of mediastinitis were included. Patients with mediastinitis received chest reconstruction (group 1). Their demographics and risk factors were matched with no-infection patients with chest reconstruction (group 2) and subjects who underwent conventional sternal closure (group 3). Chronic pain was assessed by the numeric rating scale after surgery. The assessment of the incidence and intensity of chest pain at 3 months post-surgery demonstrated that 14 out of 42 patients across all groups still experienced chronic pain. Specifically, in group 1 with sternal infection five patients had mild pain, while one patient experienced mild pain in group 2, and eight patients in group 3. Also, follow-up results indicated that the highest pain score was in group 3. While baseline levels of cytokines were increased among patients with sternal infection, at discharge only the level of interleukin 6 remained high compared to no infection groups. Compared to conventional closure, after chest reconstruction, we found better healing scores at 3-month follow-up and a higher percentage of patients with the complete sternal union. Overall, 14 out of 42 patients have chronic pain after cardiac surgery. The intensity of the pain in mediastinitis patients significantly decreased at 3 months follow-up after chest reconstruction. Thus, post-surgery mediastinitis is not a determining factor for development the chronic chest pain. There is no correlation between cytokines levels and pain score except interleukin 6 which remains elevated for a long time after treatment. Correlation between sternal healing score and chronic chest pain was demonstrated.

Comparison of procedure-related pain and patient satisfaction according to catheter size and insertion site in peripheral intravenous catheterization.

Peripheral intravenous catheterization is a painful and uncomfortable procedure and is the most commonly used invasive procedure in healthcare institutions. Compare procedure-related pain and patient satisfaction according to catheter size and insertion site in peripheral intravenous catheterization. The study was comparative prospective randomized study. Individual Information Form, Visual Analog Scale, and Patient Satisfaction Scale about Catheterization were used for data collection. The highest pain score and the lowest patient satisfaction were determined in 20 gage insertion in the dorsum of the hand. It was less painful to perform the procedure in the forearm than in the dorsum of the hand. Moreover, there was a significant negative correlation between the level of pain experienced due to peripheral intravenous catheterization and patient satisfaction with catheterization. A smaller peripheral intravenous catheter inserted in the forearm resulted in less pain sensation and higher patient satisfaction.

Aseptic Glenoid Baseplate Loosening after Reverse Total Shoulder Arthroplasty with a Single Prosthesis.

Early reverse total shoulder arthroplasty (rTSA) designs had high failure rates, mainly from loosening of the glenoid baseplate. The purpose of this study is to determine the incidence of aseptic glenoid baseplate loosening after primary rTSA using a contemporary medialized glenoid/lateralized humeral system and identify significant risk factors associated with loosening. 7,162 primary rTSA were treated with a single platform rTSA system between April 2007 and August 2021, from which 3,127 primary rTSA patients with a minimum 2-year follow-up were identified. Patients with aseptic glenoid baseplate loosening were compared to all other primary rTSA without loosening. Univariate and multivariate analyses were performed to compare these cohorts and identify the demographic, comorbidities, operative, and implants associated aseptic glenoid loosening after rTSA. Odds ratios were calculated for each significant risk factor and for multiple combinations of risk factors. Irrespective of minimum follow-up, fifty-three (31F/22M) of 7,162 primary rTSA shoulders experienced aseptic glenoid loosening, for an overall rate of 0.74%. At latest 2-year minimum follow-up, thirty of 3,127 patients experienced aseptic glenoid loosening and had significantly lower clinical scores, function, active ROM, and higher pain scores as compared to patients without loosening. Univariate analysis identified that patients with rheumatoid arthritis (RA, p=0.029, OR = 2.74) and diabetes (p=0.028, OR=1.84) and multivariate analysis identified Walch glenoid types B2 (p=0.002, OR= 4.513) and B3 (p=0.002, OR=14.804), use of expanded lateralized glenospheres (p=0.025, OR=2.57) and use of augmented baseplates (p=0.001, OR=2.50) as significant risk factors for aseptic glenoid loosening after rTSA. The incidence of aseptic glenoid baseplate loosening was 0.74% for this medialized glenoid/lateralized humeral rTSA system. Numerous risk factors for aseptic loosening were identified, including: RA, diabetes, Walch B2 and B3 glenoids, posterior/superior augmented baseplates, and expanded lateralized glenospheres. Finally, analysis of multiple combinations of risk factors identified patients and implant configurations with the greatest risk of aseptic glenoid loosening.

Do physical tests have a prognostic value in chronic midportion Achilles tendinopathy?

To determine whether baseline physical tests have a prognostic value on patient-reported outcomes in Achilles tendinopathy. Prospective cohort study, secondary analysis of data from a randomized trial. Patients with chronic midportion Achilles tendinopathy performed a progressive calf muscle exercise program. At baseline and after 2, 6, 12 and 24 weeks, patients completed the Victorian Institute of Sports Assessment-Achilles questionnaire and performed the following physical tests: ankle dorsiflexion range of motion with a bent knee or an extended knee, calf muscle strength, jumping height and pain on palpation (Visual Analogue Scale; 0-100) and after 10 hops (Visual Analogue Scale-10-hops). Associations between baseline test results and improvement (Victorian Institute of Sports Assessment-Achilles scores) were determined using a Mixed Linear Model. 80 patients were included. The mean Victorian Institute of Sports Assessment-Achilles score improved 20 points (95 % confidence interval, 16-25, P < .001) after 24 weeks. There were significant associations between the baseline ankle dorsiflexion range of motion with a bent knee (β 0.2, 95 % confidence interval 0.001 to 0.3, P = .049), the baseline pain provocation tests (Visual Analogue Scale palpation: β -0.2; 95 % confidence interval: -0.4 to -0.1; P < .001, Visual Analogue Scale-10-hops: β -0.3; 95 % confidence interval: -0.4 to -0.2; P < .001) and the change in the Victorian Institute of Sports Assessment-Achilles score. In patients with chronic midportion Achilles tendinopathy, easy-to-perform pain provocation tests have a clinically relevant prognostic value on patient-reported improvement. Patients with less pain during pain provocation tests at baseline have a better improvement in pain, function and activities after 24 weeks than patients with high baseline pain scores.

Cystoscopy, an indispensable tool for the diagnosis and prognosis of bladder pain syndrome, takes nomograms for predicting recurrence.

We aimed to illustrate the importance of cystoscopy for the diagnosis and prognosis of bladder pain syndrome (BPS) or interstitial cystitis (IC). We designed a 4-year prospective follow-up study. Patients who underwent cystoscopy between May 2011 and July 2021 with a diagnosis of BPS/IC before surgery or positive cystoscopic findings during initial surgery at Peking University People's Hospital were enrolled. Data related to symptom recurrence were obtained through clinic visits and telephone follow-up. We compared the differences in clinical features of BPS/IC subtypes differentiated by cystoscopy and first created clinical predictive nomograms for BPS/IC. A total of 141 patients were included. There was an 8.51% chance of BPS/IC being misdiagnosed as other diseases or other diseases being misdiagnosed as BPS/IC without cystoscopy. Patients with HIC had higher pain scores and ICPI, higher residual urine volume, lower first-sense-to-void, and maximum cystometric bladder capacities than NHIC. Nomogram Models showed that patients who with higher ICPI, ICSI and lower AMBC have a greater recurrence probability, and lesions in the trigone may indicate a greater likelihood of recurrence than lesions in other bladder walls. Timely detection of bladder cancer and other diseases using cystoscopy can avoid poor treatment effects. BPS/IC subtypes can be classified according to mucosal changes under cystoscopy. Lesions in the bladder triangle can indicate a higher recurrence risk, which is important in follow-up treatment. We strongly recommend that cystoscopy should be included in the international BPS/IC diagnostic criteria.

Self-Reported Pain and Pain Observations in People with Korsakoff's Syndrome: A Pilot Study.

Korsakoff's syndrome (KS) is a chronic neuropsychiatric disorder. The large majority of people with KS experience multiple comorbid health problems, including cardiovascular disease, malignancy, and diabetes mellitus. To our knowledge pain has not been investigated in this population. The aim of this study was to investigate self-reported pain as well as pain behavior observations reported by nursing staff. In total, 38 people diagnosed with KS residing in a long-term care facility for KS participated in this research. The Visual Analogue Scale (VAS), Pain Assessment in Impaired Cognition (PAIC-15), Rotterdam Elderly Pain Observation Scale (REPOS), and the McGill Pain Questionnaire-Dutch Language Version (MPQ-DLV) were used to index self-rated and observational pain in KS. People with KS reported significantly lower pain levels than their healthcare professionals reported for them. The highest pain scores were found on the PAIC-15, specifically on the emotional expression scale. Of importance, the patient pain reports did not correlate with the healthcare pain reports. Moreover, there was a high correlation between neuropsychiatric symptoms and observational pain reports. Specifically, agitation and observational pain reports strongly correlated. In conclusion, people with KS report less pain than their healthcare professionals indicate for them. Moreover, there is a close relationship between neuropsychiatric symptoms and observation-reported pain in people with KS. Our results suggest that pain is possibly underreported by people with KS and should be taken into consideration in treating neuropsychiatric symptoms of KS as a possible underlying cause.

Cross-cultural adaptation and validation of the Spanish version of the Oswestry disability index for Mexican population

Purpose This study aimed to adapt a Spanish translation of the Oswestry Disability Index (ODI) into a cross-cultural version for the Mexican population. The objectives were to verify the validity and reliability of the adapted ODI and to compare pain perception between patients with and without obesity. Material and methods We included 102 patients with low back pain from two neurosurgery departments in Mexico. The ODI questionnaire was translated and culturally adapted. Validity and construct were evaluated using exploratory factor analysis, and the external convergent validity was assessed by correlating ODI scores with pain intensity, age, and obesity. Test-retest reliability was calculated using the intraclass correlation coefficient, and confirmatory analysis was employed to validate the factorial structure. Results Patients with obesity were older and had higher pain scores than patients without obesity. The exploratory analysis of the ODI in Mexican Spanish showed good reliability (Cronbach’s alpha of 0.923) and validity (factorial loading range, 0.681 − 0.818). The confirmatory analysis showed almost null or very low discrepancy between the proposed model and the real data. Conclusions A Spanish translation of ODI was cross-culturally adapted for the Mexican population. The Mexican version of the ODI showed good reliability and validity in Mexican culture.

Influence of the Dose and Frequency of Administration of Tramadol on Analgesia, Hematological, Biochemical Parameters, and Oxidative Status of Cats Undergoing Ovariohysterectomy

This study aimed to evaluate the effects of the repeated administration of tramadol subcutaneously on postoperative analgesia, liver, kidneys, and oxidative status in the postoperative period of cats undergoing ovariohysterectomy. Thirty-seven cats were randomly assigned to 5 groups, according to the postoperative analgesic treatment: NaCl 0.9%, GC; tramadol at 2 mg/kg, T2B (q12h) and T2T (q8h); or 4 mg/kg, T4B (q12h) and T4T (q8h). Oxidative status was assessed at baseline, 12 hours and 24 hours after the final administration of tramadol by the activity of superoxide dismutase (SOD), catalase (CAT), myeloperoxidase (MPO), butyrylcholinesterase (BuChE), and lipoperoxidation (MDA). Total blood count, serum biochemistry and urinalysis were compared between baseline and 12 hours posttramadol. Postoperative pain was evaluated by applying the Glasgow Feline Composite Measure Pain Scale at baseline, 3 (T3), 6 (T6), 8 (T8), 12 (T12), 24 (T24) e 36 (T36) hours after extubation. No side effects were observed. Tramadol increased SOD activity while CAT varied among groups in all time points but not over time. MDA levels increased from baseline to 12 hours in all groups but T4T. MPO activity decreased from baseline to 24 hours in some groups, including GC. Creatinine and phosphatase alkaline decreased in T2T, T4B, and T4T at 12 hours. Higher pain scores were observed from T3 to T8, except for GC. Rescue analgesia was administered only at T3. No difference in pain scores was observed from T8 onwards. Based on the findings, it is suggested that tramadol at 2 mg/kg every 8 hours is recommended for postoperative analgesia of cats undergoing ovariohysterectomy.

Pain assessment in women with or without endometriosis during the IVF process: a prospective study

Research questionHow does the typology and effect of pain vary between infertile patients with or without endometriosis during the different stages of the IVF process? DesignA prospective, monocentric, observational cohort study was conducted at Lille University Hospital between November 2019 and June 2021. The study was proposed to all patients starting an IVF cycle. Pain assessment questionnaires using validated scales (about type of pain, without specific location), were completed by patients at key points during IVF: before starting treatment, at the end of stimulation and on the day of oocyte retrieval. ResultsA total of 278 patients were analysed: 73 patients with endometriosis and 205 without. At the start of the IVF process, patients with endometriosis had higher pain scores than disease-free women (mean numerical scale score 3.47 versus 1.12 [P < 0.0001]) and 17.81% of patients with endometriosis had neuropathic pain. For mental disorders before starting treatment, 22% of patients with endometriosis had suspected or confirmed depression, and 33% had anxiety compared with 8% and 20% in patients without endometriosis, respectively. During IVF, for patients without endometriosis, pain increased significantly between the baseline, the end of stimulation and on the day of retrieval (P ≤ 0.05). In patients with endometriosis, however, pain did not significantly vary during these times. ConclusionEndometriosis is associated with higher pain scores, but no increase in pain was observed during IVF for these patients. It seems essential to screen and characterize pain phenotypes in all patients before starting treatment and during stimulation to improve pain management.

Ultrasound findings in painful spastic hip. Muscle thickness in children with cerebral palsy

BackgroundIn cerebral palsy (CP), spasticity is the dominant symptom and hip pain is one of the most common secondary conditions. Aetiology is not clear. Musculoskeletal ultrasound (MSUS) is a low-cost, non-invasive imaging technique that allows assessment of structural status, dynamic imaging, and quick contralateral comparison.ObjectiveA retrospective case-matched-control study. To investigate associated factors with painful spastic hip and to compare ultrasound findings (focusing on muscle thickness) in children with CP vs. typically developing (TD) peers.SettingPaediatric Rehabilitation Hospital in Mexico City, from August to November 2018.Participants21 children (13 male, 7 + 4.26 years) with CP, in Gross Motor Function Classification System (GMFCS) levels IV to V, with spastic hip diagnosis (cases) and 21 children age- and sex-matched (7 + 4.28 years) TD peers (controls).Characteristically dataSociodemographic data, CP topography, degree of spasticity, mobility arch, contractures, Visual Analog Scale (VAS), GMFCS, measurements of the volumes of eight major muscles of the hip joint and MSUS findings of both hips.ResultsAll children with CP group reported chronic hip pain. Associated factors for hip pain (high VAS hip pain score) were degree of hip displacement (percentage of migration), Ashworth Level, GMFCS level V. No synovitis, bursitis or tendinopathy was found. Significant differences (p < 0.05) were found in muscle volumes in all hip muscles (right and left) except in the right and left adductor longus.ConclusionThough possibly the most important issue with diminished muscle growth in CP children is the influence on their long-term function, it is likely that training routines that build muscle size may also increase muscle strength and improve function in this population. To improve the choice of treatments in this group and maintain muscle mass, longitudinal investigations of the natural history of muscular deficits in CP as well as the impact of intervention are needed.

Post-surgical discharge opioid prescribing, use and handling after introduction of a stewardship program.

SummaryOpioids are often used to provide postsurgical analgesia but may cause harm if used inappropriately. We introduced an opioid stewardship program in three Melbourne hospitals to reduce the inappropriate use of opioids after patient discharge. The program had four pillars: prescriber education, patient education, a standardised quantity of discharge opioids, and general practitioner (GP) communication. Following introduction of the program, we undertook this prospective cohort study. The study aimed to describe post-program discharge opioid prescribing, patient opioid use and handling, and the impact of patient demographics, pain and surgical treatment factors on discharge prescribing. We also evaluated compliance with the program components. We recruited 884 surgical patients from the three hospitals during the ten-week study period. Discharge opioids were dispensed to 604 (74%) patients, with 20% receiving slow-release opioids. Junior medical staff undertook 95% of discharge opioid prescribing, which was guideline-compliant for 78% of patients. Of the patients discharged with opioids, a GP letter was sent for only 17%. Follow-up at two weeks was successful in 423 (70%) patients and in 404 (67%) at three months. At the three-month follow-up, 9.7% of patients reported ongoing opioid use; in preoperatively opioid naïve patients, the incidence was 5.5%. At the two-week follow-up, only 5% reported disposal of excess opioids, increasing to 26% at three months. Ongoing opioid therapy at three months in our study cohort (9.7%; 39/404) was associated with preoperative opioid consumption and higher pain scores at the three-month follow-up. The introduction of the opioid stewardship program resulted in highly guideline-compliant prescribing, but hospital-to-GP communication was uncommon and opioid disposal rates were low. Our findings suggest that opioid stewardship programs can improve postoperative opioid prescribing, use and handling, but the realisation of these gains will require effective program implementation.

Comparison of the effects of Valsalva maneuver, EMLA cream, and the combination of both in relieving pain of needle insertion on totally implantable access port: A randomized controlled study.

Totally implantable access port (TIAP) is a subcutaneously implanted, long-term infusion device that is widely used in oncology patients. However, multiple needle insertions into TIAP may lead to pain, anxiety, and dread in patients. This study aimed to compare the effectiveness of Valsalva maneuver, eutectic mixture of local anesthetics (EMLA) cream, and the combination of both in relieving pain of cannulations on TIAP. This was a prospective randomized controlled study. We included 223 patients treated with antineoplastic drugs and randomized them into four groups: EMLA Group (Group E), control Group (Group C), Valsalva maneuver Group (Group V), and EMLA cream combing with Valsalva maneuver Group (Group EV). Each group was given the corresponding intervention before non-coring needle insertion. The data on pain scores and overall comfort were collected by numerical pain rating scale (NPRS) and visual analog scale (VAS). Group E and Group EV experienced the least amount of pain scores in needle insertion, which was significantly lower than Group V and Group C (p < 0.05). Meanwhile, Group E and Group EV obtained the highest comfort level, which was significantly higher than group C (p < 0.05). Fifteen patients developed localized skin erythema after the application of medical Vaseline or EMLA cream and subsided within half an hour after rubbing. EMLA cream is a safe and effective way to alleviate pain during non-coring needle insertion in TIAP and enhance the overall comfort of patients. We recommend applying EMLA cream 1 h before needle insertion of TIAP, especially in patients having needle phobia or high pain scores from previous non-coring needle insertion.

Joint tenderness at 3 months follow-up better predicts long-term pain than baseline characteristics in early rheumatoid arthritis patients.

To investigate pain course over time and to identify baseline and 3-month predictors of unacceptable pain with or without low inflammation in early RA. A cohort of 275 patients with early RA, recruited in 2012-2016, was investigated and followed for 2 years. Pain was assessed using a visual analogue scale (VAS; 0-100 mm). Unacceptable pain was defined as VAS pain >40, and low inflammation as CRP <10 mg/l. Baseline and 3-month predictors of unacceptable pain were evaluated using logistic regression analysis. After 2 years, 32% of patients reported unacceptable pain. Among those, 81% had low inflammation. Unacceptable pain, and unacceptable pain with low inflammation, at 1 and 2 years was significantly associated with several factors at 3 months, but not at baseline. Three-month predictors of these pain states at 1 and 2 years were higher scores for pain, patient global assessment, and the health assessment questionnaire, and more extensive joint tenderness compared with the number of swollen joints. No significant associations were found for objective inflammatory measures. A substantial proportion of patients had unacceptable pain with low inflammation after 2 years. Three months after diagnosis seems to be a good time-point for assessing the risk of long-term pain. The associations between patient reported outcomes and pain, and the lack of association with objective inflammatory measures, supports the uncoupling between pain and inflammation in RA. Having many tender joints, but more limited synovitis, may be predictive of long-term pain despite low inflammation in early RA.

SAFETY AND EFFICACY OF DULOXETINE IN PATIENTS UNDERGOING TOTAL HIP OR KNEE ARTHROPLASTY: A SYSTEMATIC REVIEW AND META-ANALYSIS OF RANDOMIZED CONTROLLED TRIALS.

Patients undergoing total hip or knee arthroplasty (THA/TKA) are commonly associated with high pain scores and narcotic use. Duloxetine is effective in relieving chronic pain. The aim of this study was to evaluate the safety and efficacy of duloxetine for pain management following THA/TKA.Five major databases (PubMed, Embase, Scopus, Cochrane, and Web of Science) were searched for randomised controlled trials (RCTs) that compared duloxetine to placebo in patients that underwent THA/TKA. The primary outcome was pain reduction with rest and movement at short-term and long-term time intervals. Secondary outcomes were the use of analgesics, length of stay, and safety profile. The risk of bias was assessed using the Cochrane tool. Data were pooled using RevMan 5.4. The results were reported as mean difference (MD) or standardised MD (SMD) and 95% confidence intervals (CI).Eight RCTs with 767 patients were included. 50.2% (n=385/767) of patients received duloxetine. After one day, duloxetine was superior to the control regarding pain reduction with rest (SMD= −0.22 [−0.41, −0.03], p=0.02) after sensitivity analysis and pain reduction at movement (SMD= −0.39 [−0.55, −0.24], p&lt;0.001). Similarly, after 12 weeks, duloxetine significantly reduced pain with rest (SMD= −0.3 [−0.52, −0.09], p=0.006) and pain with movement (SMD= −0.52 [−0.87, −0.17], p=0.003). In addition, after sensitivity analysis, duloxetine was associated with less analgesic use after one day (MD= −4.65 [−7.3, −2.01], p&lt;0.001) and two days (MD= −5.65 [−10.62, −0.67], p=0.03). Patients who received duloxetine also required fewer analgesics after three days. However, there was no significant difference between the duloxetine and control groups in analgesic use after one week, length of stay, and adverse events.Duloxetine was superior to the placebo regarding short-term and long-term pain reduction with rest and movement following THA/TKA. Duloxetine reduced postoperative analgesic use. There was no significant difference between duloxetine and placebo regarding adverse events and length of stay.

Adverse Events of Light-Assisted Hair Removal: An Updated Review.

With light-assisted hair removal becoming widely used, reports of adverse effects are increasing. To review all the reported optical incidents and cutaneous complications of laser or intense pulse light-assisted hair removal. A PubMed database systematic search was performed to identify studies reporting such adverse events before July 2022 using the Mesh terms "adverse effects" AND "hair removal" AND ("laser" OR "intense pulse light"). Altogether, 358 references were identified. After excluding duplicates, unrelated articles, guidelines, and conference abstracts, then adding references from studies bibliography, 104 publications were included. Ocular incidents consisted of anterior uveitis, iritis and iris atrophy, pupillary distortion, posterior synechiae, anterior chamber pigment, and cataracts in the anterior subcapsular region. Cutaneous complications consisted of pain, burns, folliculitis, leukotrichia, paradoxical hypertrichosis, pigmentary changes, changes in nevi, pili bigemini, herpes infection, hyperhidrosis, bromhidrosis, Fox-Fordyce disease, and frostbite from the cooling system. They were mostly correlated to skin type and body area as well as to light device and set parameters. Intense pulse light devices were found to be less painful than alexandrite laser, yet more painful than diode laser; Nd:YAG laser had the highest pain score. Optical incidents can be systematically avoided. Cutaneous complications are usually related to professional errors and patient characteristics. Better knowledge of laser physics and adequate training of laser operators are key recommendations to avoid undesirable side effects. Safety recommendations help prevent most of the reported complications.

Technology-guided assessment of vocalisations and their diagnostic value as pain indicators for people living with dementia.

during pain assessment in persons unable to self-report, such as people living with dementia, vocalisations are commonly used as pain indicators. However, there is a lack of evidence from clinical practice regarding their diagnostic value and relationship with pain. We aimed to explore vocalisations and pain in people with dementia undergoing pain assessments in clinical practice settings. a total of 22,194 pain assessments were reviewed in people with dementia (n = 3,144) from 34 different Australian aged care homes and two dementia specific programs. Pain assessments were conducted by 389 purposely trained health care professionals and cares using PainChek pain assessment tool. Vocalised expressions were determined based on nine vocalisation features included in the tool. Linear mixed models were used to examine the relationship of pain scores with vocalisation features. Using a single pain assessment for each of the 3,144 people with dementia, additional data analysis was conducted via Receiver Operator Characteristic (ROC) analysis and Principal Component Analysis. vocalisation scores increased with increasing pain intensity. High pain scores were more likely with the presence of sighing and screaming (8 times). The presence of vocalisation features varied depending on the intensity of pain. The ROC optimal criterion for the voice domain yielded a cut-off score of ≥2.0 with a Youden index of 0.637. The corresponding sensitivity and specificity were 79.7% [confidence interval (CI): 76.8-82.4%] and 84.0% (CI: 82.5-85.5%), respectively. we describe vocalisation features during presence of different levels of pain in people with dementia unable to self-report, therefore providing evidence in regard to their diagnostic value in clinical practice.

Adherence to Opioid Patient Prescriber Agreements at a Safety Net Hospital.

Patient prescriber agreements, also known as opioid contracts or opioid treatment agreements, have been recommended as a strategy for mitigating non-medical opioid use (NMOU). The purpose of our study was to characterize the proportion of patients with PPAs, the rate of non-adherence, and clinical predictors for PPA completion and non-adherence. This retrospective study covered consecutive cancer patients seen at a palliative care clinic at a safety net hospital between 1 September 2015 and 31 December 2019. We included patients 18 years or older with cancer diagnoses who received opioids. We collected patient characteristics at consultation and information regarding PPA. The primary purpose was to determine the frequency and predictors of patients with a PPA and non-adherence to PPAs. Descriptive statistics and multivariable logistic regression models were used for the analysis. The survey covered 905 patients having a mean age of 55 (range 18-93), of whom 474 (52%) were female, 423 (47%) were Hispanic, 603 (67%) were single, and 814 (90%) had advanced cancer. Of patients surveyed, 484 (54%) had a PPA, and 50 (10%) of these did not adhere to their PPA. In multivariable analysis, PPAs were associated with younger age (odds ratio [OR] 1.44; p = 0.02) and alcohol use (OR 1.72; p = 0.01). Non-adherence was associated with males (OR 3.66; p = 0.007), being single (OR 12.23; p = 0.003), tobacco (OR 3.34; p = 0.03) and alcohol use (OR 0.29; p = 0.02), contact with persons involved in criminal activity (OR 9.87; p < 0.001), use for non-malignant pain (OR 7.45; p = 0.006), and higher pain score (OR 1.2; p = 0.01). In summary, we found that PPA non-adherence occurred in a substantial minority of patients and was more likely in patients with known NMOU risk factors. These findings underscore the potential role of universal PPAs and systematic screening of NMOU risk factors to streamline care.

Low- and high-frequency spinal cord stimulation and arterial blood pressure in patients with chronic pain and hypertension: a retrospective study.

Evidence suggests that traditional low-frequency spinal cord stimulation (LF-SCS) reduces arterial blood pressure (BP) in patients with chronic pain and hypertension independent of improved pain symptoms. However, it remains unclear whether high-frequency spinal cord stimulation (HF-SCS) also lowers BP in chronic pain patients with hypertension. Therefore, in a retrospective study design, we tested the hypothesis that clinic BP would be significantly reduced following implantation of HF-SCS in patients with chronic pain and hypertension. Clinic BP within 3months before and after surgical implantation of either a LF-SCS or HF-SCS device between 2010 and 2020 were collected from electronic medical records at The University of Kansas Health System (TUKHS). A total of 132 patients had available records of clinic BP (64 ± 13years of age). Patients with hypertension (n = 32) demonstrated a significantly greater reduction in systolic BP (-8 ± 12 versus 2 ± 9mmHg, P < 0.001) following implantation compared with normotensive patients (n = 100). Importantly, the change in BP was inversely related to baseline BP independent of age and sex following implantation of HF-SCS (n = 70, R = -0.50, P < 0.001) or LF-SCS (n = 62, R = -0.42, P = 0.001). Higher pain scores before implantation were not associated with reduction in systolic BP (R = 0.10, P = 0.43) or diastolic BP (R = -0.08, P = 0.53) (n = 69) after implantation. These findings confirm previous studies showing reduced BP following implantation of LF-SCS in patients with chronic pain and hypertension and provide novel data regarding reduced BP following implantation of newer generation HF-SCS devices.

Development and validation of a nomogram for postoperative sleep disturbance in adults: a prospective survey of 640 patients undergoing spinal surgery

BackgroundPostoperative sleep disturbance (PSD) is a prevalent clinical complication that may arise due to various factors. The purpose of this investigation is to identify the risk factors for PSD in spinal surgery and establish a risk prediction nomogram.MethodsThe clinical records of individuals who underwent spinal surgery from January 2020 to January 2021 were gathered prospectively. The least absolute shrinkage and selection operator (LASSO) regression, along with multivariate logistic regression analysis, was employed to establish independent risk factors. A nomogram prediction model was devised based on these factors. The nomogram’s effectiveness was evaluated and verified via the receiver operating characteristic (ROC) curve, calibration plot, and decision curve analysis (DCA).ResultsA total of 640 patients who underwent spinal surgery were analyzed in this investigation, among which 393 patients experienced PSD with an incidence rate of 61.4%. After conducting LASSO regression and logistic regression analyses using R software on the variables in training set, 8 independent risk factors associated to PSD were identified, including female, preoperative sleep disorder, high preoperative anxiety score, high intraoperative bleeding volume, high postoperative pain score, dissatisfaction with ward sleep environment, non-use of dexmedetomidine and non-use of erector spinae plane block (ESPB). The nomogram and online dynamic nomogram were constructed after incorporating these variables. In the training and validation sets, the area under the curve (AUC) in the receiver operating characteristic (ROC) curves were 0.806 (0.768–0.844) and 0.755 (0.667–0.844), respectively. The calibration plots indicated that the mean absolute error (MAE) values in both sets were respectively 1.2% and 1.7%. The decision curve analysis demonstrated the model had a substantial net benefit within the range of threshold probabilities between 20% and 90%.ConclusionsThe nomogram model proposed in this study included eight frequently observed clinical factors and exhibited favorable accuracy and calibration.Trial registrationThe study was retrospectively registered with the Chinese Clinical Trial Registry (ChiCTR2200061257, 18/06/2022).

Association Between ACEs and Postoperative Pain After Gynecologic Surgery [ID: 1377683

INTRODUCTION: Adverse childhood experiences (ACEs) are instances of abuse or household dysfunction that occur prior to 18 years of age. Numerous studies have demonstrated an increased risk of morbidity and mortality with increasing ACE scores. An association between ACEs and chronic pelvic pain has also been described; however, data for acute pain are lacking. This study evaluates the relationship between ACEs and acute postoperative pain after benign minimally invasive hysterectomies. METHODS: Institutional review board approval was obtained at a large academic health center. Consenting participants completed the ACEs survey prior to hysterectomy. Patient data were collected by retrospective chart review, including postoperative care unit pain scores. Descriptive statistics, Kruskal-Wallis tests, and Spearman’s correlation coefficients were utilized for analysis. Enrollment is ongoing with a recruitment goal of 112 participants. RESULTS: Preliminary analysis included 47 participants. Average patient age was 39.2±11.4 years. The average ACE score was 3.5±2.9 and 46.8% of participants had high ACE scores, defined as 4 or more. Although not statistically significant, patients with high ACE scores trended towards higher pain scores and morphine milligram equivalents (MME) usage. Maximum pain scores and required MME were 5.86 and 16.50 MME in the high-ACE group versus 4.88 and 7.50 MME in the low-ACE group, respectively (P=.41, P=.40). CONCLUSION: High ACE scores are greater than threefold more prevalent in our surgical study population compared to previously reported general population rates. Although preliminary data suggest ACE scores and postoperative pain are not associated, further data are needed.
