Association Between Systemic Neuroinflammation, Pain Perception and Clinical Status in Fibromyalgia Patients: Cross-Sectional Study.

Fibromyalgia (FM) is characterized by chronic pain and a complex array of symptoms, with neuroinflammation implicated in its pathophysiology. This study aimed to explore the association between neuroinflammation, measured through interleukin levels (IL-1, IL-6, IL-8), and clinical outcomes in FM patients. Using a cross-sectional study design, blood levels of these interleukins were correlated with pain severity and disability, assessed via the Fibromyalgia Impact Questionnaire (FIQ) and pain measures. Results indicated that IL-6 and IL-8 may particularly serve as biomarkers for pain severity and disability in FM patients, showing significant associations with worse clinical outcomes. Elevated IL-8 levels, for instance, correlated strongly with increased pain perception and higher disability scores. These findings suggest that specific interleukins are not only elevated in FM but are actively involved in the modulation of pain and disability, underscoring the role of systemic neuroinflammation in the clinical severity of FM. This study contributes to a deeper understanding of the inflammatory mechanisms in FM and underscores the potential of targeting interleukins in therapeutic strategies.

Investigating the Association between Catechol-O-Methyltransferase Gene Activity and Pain Perception in South African Patients with Different Temporomandibular Disorders Diagnoses.

Background: Temporomandibular disorders (TMD) affect a significant portion of the population, with profound psychological, behavioral, and social repercussions. Recent investigations have explored the genetic basis underlying pain perception in individuals with TMD, aiming to elucidate the role of specific genetic factors in modulating the condition. Notably, genetic variations have been implicated in the pathogenesis of TMD, particularly genes involved in pain perception pathways. One of the primary candidates is the Catechol-O-Methyltransferase (COMT) gene, which plays a crucial role in the catecholaminergic system and has been associated with the regulation of nociceptive processes. This study seeks to investigate the correlation between COMT gene activity and pain perception among South African patients diagnosed with varying forms of TMD. Methodology: In this study, a total of 196 participants were enrolled, comprising 97 patients diagnosed with TMD and 99 control participants. The control group was meticulously matched with the TMD group for age, gender, and ethnicity. Data collection involved clinical and radiological investigations, and saliva sampling. The English version of the Diagnostic Criteria for Temporomandibular Disorders (DC/TMD) Axis I was utilized to evaluate all TMD participants, focusing on standard diagnostic measures based on clinical signs and symptoms of TMD, which primarily describe common physical manifestations of the disorder. Genomic DNA was extracted from saliva samples, enabling the analysis of single-nucleotide polymorphisms (SNPs) in the COMT gene, specifically targeting polymorphisms rs165774, rs9332377, rs6269, rs4646310, rs165656, and rs4680. Results: The current study demonstrated a pronounced gender disparity, with 80.41% of the participants being female and 19.59% male, suggesting that women in South Africa either exhibit a higher susceptibility to TMD or are more likely to seek treatment for the condition compared to men. The highest prevalence of TMD was observed in the white population (58.76%). Additionally, over 65% of TMD patients were diagnosed with at least two Axis I diagnoses, a figure that increased to 89% for those diagnosed with three Axis I diagnoses. The findings further indicated significant associations between several single-nucleotide polymorphisms (SNPs) in the Catechol-O-Methyltransferase (COMT) gene-specifically rs165656, rs9332377, rs4646310, rs6269, and rs165774-and both TMD and TMD-related pain. Myofascial pain with referral and myalgia showed a strong association with the COMT SNPs rs9332377 and rs4646310. Furthermore, COMT SNP rs4646310 was also associated with disability related to TMD. Conclusions: This study substantiates the hypothesis that pain is prevalent in a considerable proportion of patients affected by TMD. Furthermore, the findings reveal a significant association between COMT gene activity and pain perception in South African patients diagnosed with TMD.

Assessment of Computer-Controlled Starpen Device and Conventional Aspirating Cartridge on Pain Perception in Paediatric Dental Patients – A Split-Mouth Crossover Study

Abstract Background: Local anaesthesia (LA) is the cornerstone for pain management of invasive dental procedures, but the process of delivering it may itself induce anxiety, especially in paediatric patients that can affect the pain perception. Advances such as the computer-controlled LA delivery system have expanded the horizons of LA and can serve as an alternative for painless injections. Objective: To examine the pain perception and anxiety reduction along with patient preference between computer-controlled Starpen device and conventional aspirating cartridge in LA administration for inferior alveolar nerve block. Materials and Methods: The patients were randomly allotted into two groups: Starpen and Septodont syringe where the LA injections were given using both the methods in the 1st week. After a washout period of 1 week, the crossover was performed and the other mode of LA administration was performed in the 2nd week. Pain scores were objectively recorded by the observer using the Face, Legs, Activity, Cry and Consolability (FLACC) scale during LA administration and extraction. Patients were asked to record the pain scores using the Visual Analogue Scale at three phases: (a) mucosa perforation, (b) needle insertion and (c) solution injection. The effect of pain perception on the vital parameters and the preference between the two techniques were assessed. Statistical Package for the Social Sciences (SPSS) version 23.0, Armonk, NY, USA: IBM Corp was used for statistical analysis, and Mann–Whitney U-test and unpaired t-test were utilised to compare the mean difference of two groups at significance level of 0.05. Results and Observations: Intergroup differences among the Starpen and Septodont syringe groups were found to be statistically significant (P < 0.001) during both LA and extraction when pain was objectively assessed using FLACC. Conclusion: Computerised devices such as Starpen offer controlled release of local anaesthetics, effectively decreasing pain perception in paediatric patients and can form a mainstay for the behaviour management of young patients.

Pain Perception, Knowledge, Attitude, and Diet Diversity in Patients Undergoing Fixed Orthodontic Treatment: A Pilot Study.

This study aimed to determine the correlation between pain perception and knowledge, attitude, and diet diversity in patients undergoing fixed orthodontic treatment. A total of 103 patients (15-40 yrs.; 67 females, 36 males) undergoing orthodontic treatment with a 0.022-inch slot (MBT prescription) in both arches were recruited. Information on pain perception, knowledge, attitude, and diet diversity scores was collected through validated questionnaires using visual analogue scale and close-ended questions at one time point. The correlation between variables was analyzed using the Pearson's correlation coefficient. Of the patients, 48.5% were aged 15 to 19 years old, with 65% females and 73.8% of Chinese ethnicity. Approximately 90% of the orthodontic patients perceived low levels of pain from orthodontic treatment, and 98% had a positive attitude toward orthodontic treatment. The patients had a good level of knowledge (Mean: 6±0.65). Approximately 49.5% of patients reported having moderate diet diversity. No significant correlation was found between pain perception and knowledge, or pain perception and diet diversity (r=0.062, p=0.534). However, a significant weak negative correlation (r=-0.289, p<0.05) between pain perception and attitude was observed. Patients undergoing fixed orthodontic treatment presented with overall low pain perception, a positive attitude, and good knowledge about their treatment with moderate diet diversity. Informing the patient in advance about different orthodontic procedures encourages a positive attitude and facilitates patient cooperation. An interprofessional approach involving nutritionists can provide a holistic patient approach during orthodontic treatment.

Effects of Music Therapy on Postoperative Pain Perception in Patients Undergoing Abdominal Surgeries Under General Anesthesia: A Prospective Controlled Randomized Comparative Clinical Study.

Background Music therapy has been shown to reduce the need for sedation and analgesics, as well as lower plasma cortisol and epinephrine levels in patients undergoing regional anesthesia. This study evaluates the efficacy of perioperative music therapy in reducing pain perception and its impact on cortisol levels. Materials and methods This prospective randomized control trial was conducted at the tertiary care center in Western Maharashtra. Sixty adult patients (males/females) undergoing elective lower abdomen surgery were included and randomized equally into two groups to listen to music using headphones at a preselected volume (Group M) or to use only headphones without any music played (Group C) for 2 hours in the preoperative, intraoperative, and postoperative periods. Demographic information, anthropometric (height, weight), and biochemical (serum cortisol) measurements were performed. American Society of Anesthesiologists (ASA) grades 1 and 2, and patients aged 18 to 65 years were included. Pain perception was assessed using the Visual Analog Scale (VAS). Results The demographic data, including mean age, BMI, ASA status, average duration of anesthesia, and average duration of surgery, were comparable between the two groups. Group M showed improved control of systolic blood pressure (SBP) at 10- and 30-minutepost-induction of general anesthesia and had a significantly lower VAS score (p < 0.05). Additionally, patient satisfaction was higher in Group M (81.4%) compared to Group C (51.4%) with a p-value of < 0.05. Intraoperative awareness was non-significant between the groups. Conclusion Music therapy is a safe, cost-effective, and efficacious method for reducing pain perception and can be used in conjunction with other treatments for postoperative pain management.

Effects of a telehealth-delivered Mediterranean diet intervention in adults with Rheumatoid Arthritis (MEDRA): a randomised controlled trial

ObjectiveTo compare the effects a Mediterranean diet (MedDiet) versus the Irish Healthy Eating Guidelines (HEG) on physical function and quality of life in adults with rheumatoid arthritis (RA) in Ireland.MethodsForty-four adults with RA were randomised (1:1) to the MedDiet or HEG for 12 weeks. The intervention included three video teleconsultations and two follow-up telephone calls facilitated by a Registered Dietitian (RD). Changes in physical function by Health Assessment Questionnaire- Disability Index (HAQ-DI) and quality of life by Rheumatoid Arthritis Quality of Life Questionnaire (RAQoL) were the primary outcomes measured. Secondary outcomes included changes in dietary adherence, physical activity by Yale Physical Activity survey (YPAS), patient-perceived pain and general health, and anthropometric measures. All measurements were administered at baseline and repeated at 6 and 12 weeks.ResultsForty participants completed the study. Participants were primarily females (87.5%), mean age was 47.5 ± 10.9 years. At the end of the intervention, participants in the MedDiet group reported significantly better physical function (p = 0.006) and quality of life (p = 0.037) compared to HEG group. From baseline to 12 weeks, physical function significantly improved in both diet groups, MedDiet (0.9 ± 0.5 to 0.5 ± 0.4 units, p < 0.001) and HEG (1.4 ± 0.7 to 1.0 ± 0.6 units, p < 0.001). Quality of life also significantly improved in the MedDiet (10.1 ± 7.5 to 4.0 ± 4.7 units, p < 0.001) and HEG group (11.25 ± 7.2 to 7.9 ± 6.4 units, p = 0.048). Physical activity improved significantly in the MedDiet (56.7 ± 28.6 to 70.6 ± 33.5 points, p = 0.01) but not within the HEG group despite similar recommendations.ConclusionAdhering to the MedDiet and Irish Healthy Eating Guidelines resulted in improvements in RA patient-reported outcomes. The changes observed in both diet groups are likely due to the improvement in overall diet quality irrespective of dietary prescription.Trial registration numberNCT04262505.

Comprehensive assessment of pain characteristics, quality of life, and pain management in cancer patients: a multi-center cross-sectional study

IntroductionPain is the most common complaint among cancer patients, significantly impairing their health-related quality of life (HRQOL). There is limited evidence on the characteristics of pain among cancer patients in Nepal with low-resource settings.ObjectivesThe primary objective of this study was to evaluate the clinical characteristics of pain, factors influencing pain intensity, and the association of pain severity with quality of life (QoL) among cancer patients. Secondary objectives included investigating perceived barriers to pain management and medication adherence among these patients.MethodsThis multi-center, cross-sectional study enrolled adult patients (over 18 years old) with reported cancer diagnoses experiencing pain. Socio-demographic characteristics (e.g., age, gender, educational status), clinical characteristics (e.g. cancer diagnosis, staging), and pain characteristics (e.g., duration, type, location, medicines used for pain management, etc.) were recorded. Outcomes were assessed using the Numeric rating scale (NRS), Pain management Index, European Organization for the Research and Treatment of Cancer Quality of Life Questionnaire, Barriers Questionnaire II, Medication Adherence Rating Scale, and Hospital Anxiety and Depression Scale.ResultsFour hundred and eight patients participated in the study. The mean ± SD age was 54.87 ± 15.65, with 226 patients (55.4%) being female. The most common cancer diagnoses were cervical (17.6%), lung (11.8%), and colon/rectum (12.0%) cancers. The most common pain locations were the head and neck (27.0%); a majority (55.6%) reported pain duration of more than 3 months. Nociceptive pain was reported by 42.4% of patients; the mean ± SD of NRS was 4.31 ± 2.69, with 32.4% of patients experiencing moderate pain. Patients with mixed pain type (B = 1.458, p < 0.001) or pain in multiple sites (B = 1.175, p < 0.001), lower Karnofsky Performance Status (KPS) (B = -1.308, p < 0.001), and specific cancer diagnoses such as prostate (B = -2.045, p = 0.002), pancreatic (B = 1.852, p = 0.004), oesophageal (B = 1.674, p = 0.012), and ovarian cancer (B = 1.967, p = 0.047), experienced varying degrees of increased NRS score. The combined chemotherapy and radiotherapy treatment modality was associated with a lower NRS score (B = -0.583, p = 0.017). A significant inverse relationship was observed between pain severity and global health status/QoL (B = -37.36, p < 0.001. Key barriers to pain management included moderate perceptions of physiological effects, communication issues between doctors and patients, and concerns about the harmful effects of pain medicine. The prevalence of non-adherence to pain medications was 13.97%.ConclusionIn conclusion, this study highlights the multi-faceted nature of pain management and QoL for cancer patients in Nepal with low-resource settings. These findings underscore the multifactorial nature of pain perception in cancer patients, with mixed pain types, pain in multiple sites, lower KPS, and specific cancer diagnoses, all contributing significantly to pain severity. Additionally, pain severity was associated with declining QoL. These findings contribute valuable insights into the complex aspects of cancer pain and its broader implications for the well-being of patients, offering a foundation for targeted interventions and improved pain management strategies in the context of cancer care in low-resource settings.

Evaluation of a novel blood collection set for venipuncture in oncology patients with difficult venous access: Impact on sample quality, phlebotomist satisfaction and patient pain perception

PurposeDifficult venous access (DVA), characterized by non-visible and non-palpable veins, is common in oncology patients. The objectives of this study were to compare the performances of two blood collection sets in an oncology phlebotomy setting: BD Vacutainer® UltraTouch™ Push Button (UT-PBBCS) and BD Vacutainer® Safety-Lok™ Blood Collection Set (SLBCS). The two sets were evaluated to assess whether use of a smaller gauge (G) needle (down-gauging) may reduce patient pain and improve peripheral venous access experience during phlebotomy in oncology patients. MethodsQuestionnaires were used to record patient data (age, gender), phlebotomy procedural observations (venipuncture site, number of collected tubes, blood flow, needle repositioning, underfilled tubes), patient pain perception and phlebotomist difficulty perception scores (0–10 points scale). Specimen quality was evaluated by hemolysis index (HI) on Roche Cobas® 6000. ResultsSubject groups showed no statistical difference. SLBCS (21/23G) or UT-PBBCS (23/25G) were used in 264 (45.8%) and 313 (54.2%) subjects respectively. Lower gauge was preferred for DVA (hand venipuncture), and DVA was associated with tube underfilling but no with type of blood collection set. For UT-PBBCS, pain perception, patients' anxiety level and phlebotomists’ difficulty grade were lower when compared to SLBCS (p < 0.001). Blood samples collected with UT-PBBCS showed less hemolysis compared to samples collected with SLBCS (p < 0.001). ConclusionProvision of a smaller gauge UT-PBBCS option during phlebotomy in oncology patients with DVA reduces procedural pain and anxiety and improved phlebotomist’ experience during sample collection. Despite the down-gauging, hemolysis was lower for UT-PBBCS, keeping sample quality while improving DVA patient comfort.

Circulating microRNAs as potential biomarkers of physical activity in geriatric patients with HCV

BackgroundCirculating microRNAs have been implicated in a diverse array of biological and pathological phenomena. Their potential utility as noninvasive biomarkers for screening and diagnosing various diseases has been proposed.ObjectiveThis study aimed to explore the potential role of the miRNAs miR-122 and miR-486 as molecular biomarkers in the pathogenesis of hepatitis C virus (HCV) infection. Thus, miR-122 and miR-486 were detected in the serum of HCV patients and healthy controls. Moreover, the potential correlations of miR-122 and miR-486 with viral complications, such as physical activity, pain, muscle fatigue, and HCV infection, were identified.MethodsA total of 150 subjects aged 30 to 66 years were included in this study. The patients were classified as patients with chronic hepatitis C virus (CHC) (n = 110) or healthy controls (n = 40). Real-time polymerase chain reaction (PCR) analyses were performed to determine miR-122 and miR-486 expression. Physical activity (PA), pain score, HCV genotyping, viral overload, aspartate transaminase (AST), alanine transaminase (ALT), lactic acid dehydrogenase (LDH), creatine kinase (CK), and antioxidant status were also estimated by using prevalidated questionnaires, PCR, and spectrophotometric analyses.ResultsCompared with those in normal controls, significant increases in the serum levels of miR-122 and miR-486 were reported in patients with CHC. In physically active CHC patients, there was a significant correlation between the expression of miRNAs and increased alanine transaminase (ALT), aspartate transaminase (AST), fibrosis scores, and inflammation activity, but no association was reported for hepatitis C virus (HCV) RNA or viral load. Additionally, significant decreases in LDH, CK, GSSG, and pain scores and increases in TAC, GSH, and the GSH/GSSG ratio were reported. Moreover, the expression of miR-122 and miR-486 was positively correlated with changes in body mass index (BMI) and liver fibrosis stage, as well as negatively correlated with sex, PA, TAC, GSH, GSSG, and the GSH/GSSG ratio.ConclusionMiR-122 and miR-486 expression levels were strongly correlated with physical activity, pain perception, and muscle fatigue biomarkers in HCV-infected patients. These miRNA levels were associated with elevated AST, ALT, fibrosis scores, LDH, CK, and antioxidant status, thus suggesting their potential as biomarkers for disease severity and oxidative stress. However, no correlation was observed with viral load or HCV-RNA expression, thus implying that these miRNAs may impact disease progression and symptoms through host factors, rather than directly affecting viral replication. In summary, the results demonstrated that molecular studies of miR-22 and miR-468 and their associations with PA, pain, adiposity, sex differences, and muscle fatigue, as well as routine biomarkers, could be useful as prognostic nanoninvasive biomarkers, thus providing novel therapeutic targets for CHC infection.

Perioperative pain perception in patients undergoing dermatologic surgery with local anesthesia - A prospective observational study.

Dermatosurgical procedures are predominantly performed under local anesthesia, yet there are few studies on perioperative pain management for extensive or staged procedures under local anesthesia. The purpose of this study was to assess pain during dermatologic surgery, describe perioperative pain management, and identify factors that influence pain perception. This prospective, monocentric study included inpatients undergoing dermatologic surgery under local anesthesia from April to December 2021. Preoperative demographic data, a pain questionnaire, and four psychometric questionnaires (PCS, LOT-R, SFQ, PHQ-9) were collected. Postoperative pain and analgesic use during the first 24hours were recorded. A total of 120 patients (with a total of 191 interventions) were included in the study. Mean postoperative pain was reported to be very low (NRS <2). Preoperative pain and expected postoperative pain were found to be predictive of postoperative pain. There was a strong correlation between catastrophizing and preoperative anxiety (r=0.65) and a moderate correlation between depression and preoperative anxiety (r=0.46). Dermatologic surgery under local anesthesia is generally considered painless. During preoperative counseling and assessment, attention should be paid to patients who fear surgery, report pain, or anticipate postoperative pain, as they have an increased risk of experiencing postoperative pain.

Association of Body Mass Index with Pain Perception, Anxiety, Depression, and Disability in Fibromyalgia Patients

Background: A disorder of uncertain origin, Fibromyalgia (FM) is accompanied by pervasive pain, tiredness, disturbed sleep, and cognitive deficit. It has been related to depression, manic-depressive illness, and chronic fatigue. FM is negatively affected by obesity on both clinical and biological parameters. Methods: A total of n=150 FM patients (132 Female and 18 Male) were included in the study. Initially, informed consent and demographic data were gathered from the participants. Afterwards, each patient's Body Mass Index (BMI) was calculated and classified into average weight, overweight, and obese categories. The Numeric Pain Rating Scale (NPRS) was used to quantify the intensity of pain, the Hamilton Anxiety Scale (HAM-A) was used to determine the participants’ anxiety levels, the Hamilton Rating Scale for Depression (HAM-D) was used to examine their depression levels, and Health Assessment Questionnaire Disability Index (HAQ-DI) was used to measure their functional status. All these questionnaires were self-administered by the participants. Results: In the NPRS, HAM-A, HAM-D, and HAQ-DI categories, no significant differences were found (p&gt;0.05). However, between the BMI level and anxiety, a weak positive correlation was detected (r=0.195, p=0.017). BMI levels were not statistically significantly correlated with pain, depression, or disability (r=0.011, p=0.0897; r=0.048, p=0.562; r=0.072, p=0.383). Conclusion: The results of the study revealed that there is no significant association of pain perception, anxiety, depression and disability with increasing BMI among FM patients except for a weak positive correlation with anxiety.

Donor site wound healing following free gingival graft surgery using platelet rich fibrin: A randomized controlled trial.

The primary purpose of this two-arm, parallel design, randomized controlled study is to compare healing of the palatal tissue donor site when platelet-rich fibrin (PRF) is used as a wound dressing compared to the use of a hemostatic agent. Secondary outcomes of patient pain perception and analgesic intake were also evaluated. Seventy-four patients receiving free gingival grafts were randomized to receive either PRF (test) or hemostatic agent (control) as a palatal wound dressing by patients selecting a sealed envelope containing their group assignment (initially 37 envelopes for PRF group and 37 for hemostatic agent group). Patient pain assessment and analgesic consumption were documented using a 21-point numerical scale (NMRS-21) at 24, 48, and 72hours post-surgery. At 1-, 2-, 3-, and 4-week follow-up appointments palatal early healing index (PEHI) scores including wound color, epithelialization, presence or absence of swelling, granulation tissue, and bleeding on gentle palpation were generated by direct intraoral examination by a blinded examiner unaware of the patients' treatment group. NMRS-21 pain scores showed a significant reduction in pain over time in both groups, with no significant difference between groups at any time point. No significant between-group difference was found in the amount of analgesics taken by patients at 24, 48, and 72hours. There was significant improvement in PEHI scores over the 4-week time period in both groups, but there was no significant difference in PEHI score at each time point (1, 2, 3, 4weeks) between groups. CONCLUSIONS: Study findings suggest that there is no difference in early palatal wound healing, patient pain perception, or analgesic consumption between use of PRF or a hemostatic agent as donor-site wound dressings.

The Effectiveness of Islamic Spiritual Therapy on the Perception of Pain Intensity and Catastrophic Pain in Female Patients with Chronic Pain

Background Chronic pain is an important medical problem that is associated with significant negative effects in many aspects of life. Based on prior studies, certain religious behaviors and having religion-based beliefs help coping with chronic diseases. this research aimed to investigate the effectiveness of Islamic spiritual therapy on the perception of pain intensity and catastrophizing of pain in patients with pain. Methods The research population included all female patients suffering from chronic pain who referred to physiotherapy and pain clinics in Shiraz in 2022; finally, 30 female patients were selected from 3 clinics using available sampling method. After meeting the inclusion criteria, they entered into the treatment process. In the pretest stage, research questionnaires including Pain catastrophizing questionnaire (pcs) (1995) and Pain Intensity Perception Questionnaire were completed and randomly assigned. The participants underwent 10 sessions of Islamic spirituality therapy, each lasted 45 min; during this time, the control group did not receive any intervention. After the end of the treatment program, the questionnaires were administered again to both groups in the form of a post-test. The data were analyzed using multivariate analysis of covariance (MANCOVA) in SPSS version 22. Result the average values of pain intensity and pain catastrophizing exhibited a reduction in the post-assessment in contrast to the pre-assessment. This disparity demonstrated statistical significance within the experimental cohort, whereas the difference between the mean values of the pre- and post-assessment in the control group were not statistically significant. It affirmed the efficacy of the intervention on the experimental group. Conclusions Based on the findings of this study, Islamic spiritual therapy approaches decrease pain intensity and pain catastrophizing in women with chronic pain and represents new horizons in clinical interventions and thus could be used as an effective interventional method to reduce psychosocial problem and increase pain tolerance.

A bundle of opioid-sparing strategies to eliminate routine opioid prescribing in a urogynecology practice

BackgroundCurrent evidence supports that many patients do not use prescribed opioids following reconstructive pelvic surgery, yet it remains unclear if it is feasible to eliminate routine opioid prescriptions without a negative impact on patients or providers. ObjectiveTo determine if there is a difference in the proportion of patients discharged without opioids after implementing a bundle of opioid-sparing strategies and tiered prescribing protocol (BOSS) compared to usual care after minimally invasive pelvic reconstructive surgery (transvaginal, laparoscopic or robotic). Secondary objectives include measures of patient-perceived pain control and provider workload. Study DesignThe BOSS intervention was implemented as a division-wide evidence-based practice change on August 1, 2022. This retrospective cohort compares a 6-month post-intervention (BOSS) cohort to 6- month pre-intervention (usual care) of patients undergoing minimally invasive pelvic reconstructive surgery. A 3-month wash out period was observed after BOSS initiation. We excluded patients <18 years, failure to consent to research, combined surgery with other specialties, urge urinary incontinence or urinary retention procedures alone, and minor procedures not typically requiring opioids. Primary outcome was measured by proportion discharged without opioids and total oral morphine equivalents (OME) prescribed. Pain control was measured by pain scores, post-discharge prescriptions and refills, phone calls and visits related to pain, and satisfaction with pain control. Provider workload was demonstrated by phone calls and post-discharge prescription refills. Data were obtained through chart review on all patients who met inclusion criteria. Primary analysis only included patients prescribed opioids according to the BOSS protocol. Two sample t tests compared continuous variables and chi-square tests compared categorical variables. Results416 patients were included in the primary analysis (207 BOSS, 209 Usual Care). Baseline demographics were similar between groups, except a lower proportion of IBS (13% vs 23%; p<0.01) and pelvic pain (15% vs 24.9%; p=0.01), and higher history of prior gynecologic surgery (69.1% vs 58.4%; p=0.02) in the BOSS cohort. The BOSS cohort was more likely to be discharged without opioids (68.1% vs 10.0%; p<.01). In those prescribed opioids, total OME on discharge was significantly lower in the BOSS cohort (48.1 vs 81.8; p<.01). The BOSS cohort had a 20.6 greater odds (CI 11.4, 37.1) of being discharged without opioids after adjusting for surgery type, arthritis/joint pain, IBS, pelvic pain, and contraindication to NSAIDs. The BOSS cohort was also less likely to receive a rescue opioid prescription after discharge (1.4% vs 9.5%; p=0.03). There were no differences in opioid prescription refills (19.7% vs 18.1%; p=0.77), emergency room visits for pain (3.4% vs 2.9%; p=0.76), postoperative pain scores (mean 4.7 vs 4.0; p=0.07), or patient satisfaction with pain control (81.5% vs 85.6%; p=0.21). After BOSS implementation, the proportion of postoperative phone calls for pain also decreased (12.6% vs 21.5%; p=0.02). Similar results were identified when non-adherent prescribing was included in the analysis. ConclusionsA bundle of evidence-based opioid sparing strategies and tiered prescribing based on inpatient use increases the proportion of patients discharged without opioids after minimally invasive pelvic reconstructive surgery without evidence of uncontrolled pain or increased provider workload.

Effect of early weight bearing program with conventional physiotherapy on functional outcomes in surgically treated proximal tibia fracture: a pilot randomized controlled trial.

Patients are often instructed to avoid weight bearing on the proximal tibia for 6 - 12 weeks post-surgery to avoid fracture fixation failure. However, delayed weight bearing leads to delayed mobility, causing difficulties in daily activities; problems such as pain, limited knee ROM, reduced quadriceps muscle strength, and impaired functional outcomes are reported in long-term follow-up. This study primarily aimed to evaluate the feasibility and explore the effect size. The secondary aim was to determine the effectiveness of early weight bearing along with conventional physiotherapy on functional outcomes. A single-blinded pilot randomized controlled trial with 30 participants with proximal tibia type I, II, and III fractures were included; they were randomized using computer-based software. Seven patients were lost to follow-up. Group I received early weight bearing along with conventional physiotherapy whereas Group II received restricted weight bearing along with conventional physiotherapy. Assessments were made on post-operative day 3 (POD-03), at discharge, at 6 weeks, and at 12 weeks. Radiographs were recorded immediately after the operation, at discharge, and at 12 weeks. A full-scale RCT is feasible with an effect size between 0.3 - 0.7. A statistically significant difference (p < 0.05) was found within both groups 12 weeks post-surgery in all outcome measures; the difference was more prominent in the intervention group. A statistically significant difference (p < 0.05) was found between both the groups post-12 weeks in all outcome measures except quadriceps isometric muscle strength. A full-scale RCT for early weight bearing along with conventional physiotherapy for patients operated for Type I, II, and III proximal tibia fracture is feasible. Early weight bearing along with conventional physiotherapy could have a positive effect on reducing patient's pain perception and increasing knee joint mobility, quadriceps isometric muscle strength, knee function, and quality of life without any adverse effects.

Salivary Testosterone Levels and Pain Perception Exhibit Sex-Specific Association in Healthy Adults But Not in Patients With Migraine

This study investigated the sex-specific associations between pain perception and testosterone levels in healthy controls (HCs) and patients with migraine. Male and female HCs and migraine patients were recruited. A series of questionnaires were completed by the participants to evaluate their psychosocial profiles, which included data on mood, stress, and sleep quality. Heat pain thresholds and suprathreshold pain ratings at 45 °C (referred to as the pain perception score [PPS]) were assessed using the Thermode system. Salivary testosterone levels were analyzed using a commercial enzyme-linked immunosorbent assay kit. A total of 88 HCs (men/women: 41/47, age: 29.9 ± 7.7 years) and 75 migraine patients (men/women: 30/45, age: 31.1 ± 7.7 years) completed all assessments. No significant differences were observed in either the psychosocial profiles or heat pain thresholds and PPSs between the sexes in the control and migraine groups. A positive correlation between testosterone levels and PPSs was identified in the male controls (r = .341, P = .029), whereas a negative correlation was identified in the female controls (r = −.407, P = .005). No such correlations were identified in the migraine group. This study confirms that a negative association is present between PPSs and testosterone levels in female controls, which is in line with the findings that testosterone is associated with reduced pain perception. Our study is the first to demonstrate a sex-specific association between PPSs and testosterone levels in HCs. Moreover, this study also revealed that the presence of migraine appears to disrupt this association. PerspectiveThis study revealed that testosterone levels demonstrate opposite associations with pain perception in healthy men and women. However, the presence of migraine appears to disrupt this sex-specific association.

Substance P concentration is associated with the inflammatory response and pain perception in patients with chronic pain in peripheral artery disease.

&lt;b&gt;Introduction:&lt;/b&gt; Previous studies indicate a significant role of the inflammatory response in the etiopathogenesis of peripheral artery disease (PAD) and chronic pain (CP).&lt;b&gt;Aim:&lt;/b&gt; The aim of the study was to determine the relationship between the concentration of SP and the level/concentration of inflammatory mediators (pro-inflammatory cytokines, positive and negative acute phase protein, anti-inflammatory cytokines) and pain intensity in people suffering from chronic pain (CP) in the course of PAD.&lt;b&gt;Material and methods:&lt;/b&gt; We examined 187 patients of the Department of Vascular Surgery. As many as 92 patients with PAD and CP (study group) were compared to 95 patients with PAD without CP (control group). The relationship between SP and the level/concentration of fibrinogen, C-reactive protein (CRP), antithrombin III (AT), serum albumin, interleukin 10 (IL-10), tumor necrosis factor alpha (TNF-α) and pain intensity (Numeric Rating Scale; NRS) was analyzed. Statistical analysis was performed using the R program, assuming the level of statistical significance of α = 0.05.&lt;b&gt;Results:&lt;/b&gt; Patients with CP had significantly higher levels of fibrinogen (P &lt; 0.001), CRP (P &lt; 0.001), SP (P &lt; 0.001), IL-10 (P &lt; 0.001), and lower serum albumin levels (P &lt; 0.023). Higher SP concentration was associated with higher levels of IL-10, CRP, and pain intensity. In both groups, SP concentration correlated negatively with the level of fibrinogen (P &lt; 0.001) as well as with albumin in the control group (P &lt; 0.001).&lt;b&gt;Conclusions:&lt;/b&gt; Thus, there is a relationship between the concentration of SP and fibrinogen, along with CRP, IL-10, and the intensity of pain in people suffering from CP in the course of PAD, and the level of albumin in the group without CP.

Comparative study of arthrocentesis with concentric-needle cannula with classic concentric needle: A randomized single-blind controlled clinical trial

This study aimed to assess and compare the efficacy of two distinct single-puncture techniques in temporomandibular joint (TMJ) arthrocentesis for managing disk displacement without reduction (DDwoR).Sixty patients with DDwoR were randomly and blindly assigned to two treatment groups (n = 30 each): group 1 — TMJ arthrocentesis with the classic concentric needle; and group 2 — TMJ arthrocentesis with the concentric needle-cannula system. The following variables were recorded and compared across the groups: patient's pain perception (visual analog scale — VAS, 0–10); maximal interincisal distance (MID, mm); facial edema (FE, presence or absence); and operation duration (OP, minutes).Patients in group 2 presented significantly lower values of VAS score and presence of FE (p < 0.05) when examining the data at 24 and 48 h after the arthrocentesis. They also showed an increase in MID values (p = 0.024) after 6 months. With regard to OP, no significant difference was observed between the groups.Performing a single-puncture TMJ arthrocentesis using a concentric needle-cannula system significantly reduced the patients’ pain perception, and mitigated the presence of facial edema during the immediate postoperative period (at 24 and 48 h). Furthermore, it resulted in a notable increase in the MID after 6 months.

The impact of a single music therapy session on pain perception of patients with sickle cell disease

Sickle Cell Disease (SCD) is a genetic condition characterized by pain. The neuromatrix theory of pain suggests pain is a multimodal experience, recognizing the importance of interventions like music therapy (MT), which address the physical and emotional pain experience. This study examined the impact of a MT session on 21 hospitalized patients’ self-reported VOC and its overall benefits. Utilizing a convergent mixed methods design, pain scores were collected prior to, during, and after sessions, with a follow-up interview. Significant changes were observed. Patients reported an average 3.03-point difference between their pre-intervention and MT-intervention score (p&lt;0.001). When pre- and post-intervention scores were compared, patients reported an average 1.9-point pain reduction (p&lt;0.001). Five themes emerged: decreased pain, increased insight, openness in verbal engagement, improved mood, and expressive freedom. The ways in which patients engaged suggest the importance of simultaneously addressing the physical, cognitive and emotional pain experience. When patients became agents of their own pain management, it engaged them in a reflexive process that altered their pain perception, improved their mood, and changed their relationship with SCD. MT is beneficial in reducing pain, simultaneously addressing the multidimensional pain experience. Further research is needed to evaluate mechanisms of impact, including addressing medication dosage.
