The Numeric Rating Scale for Clinical Pain Measurement: A Ratio Measure?

Musculoskeletal pain intensity and perceptions during distance learning: A cross-sectional study

Technological developments and the pandemic have popularized the distance learning model at universities. In this educational model, students spend more time in front of screens, and screen-related health conditions have become important. This cross-sectional study of 177 undergraduate students was designed to investigate the effect of block and traditional scheduling in online distance education (ODE) on their musculoskeletal pain and to investigate their perceptions of block scheduling. A two-stage method was used: a quantitative design to compare pain levels, and a qualitative design to determine the students' perceptions of block scheduling using an online survey. Pain intensity was assessed using the Numeric Rating Scale (NRS-11). Data were collected in the university health sciences department. Pain intensity following the block and traditional lessons was analyzed using a paired t-test. Students in the block schedule had significantly more pain, with a large effect size on the whole trunk and upper limbs. Pain levels were also clinically meaningful for the upper (5.73 ± 2.75), lower (5.59 ± 2.87), and neck (4.92 ± 2.60) regions. Students reported positive experiences with block scheduling in ODE such as saving time (43%) and maintaining subject integrity (26%), but also negative experiences such as distraction (56%), fatigue (33%), pain (17%), and boredom (11%). Block scheduling in ODE could cause clinically significant neck and back pain. In distance learning, keeping the course duration short and ensuring student mobility in the classroom are important.

Athletes and Experimental Pain: A Systematic Review and Meta-Analysis

The evidence that athletes respond to and report indices of experimental pain differently to non-athlete populations was analysed. Databases screened were SPORTDiscus, PubMED, PsycArticles, the Cochrane Library (Cochrane Database of Systematic Reviews), Web of Science, Scopus, and CINAHL. Studies that compared experimentally induced pain responses (threshold, tolerance, intensity, unpleasantness, bothersomeness, and effect on performance) in athletes and controls were included. Meta-analyses were performed where appropriate and effects were described as standardised mean differences, pooled using random effects models. Thirty-six studies (2,492 participants) met the inclusion criteria comprising 19 pain tolerance, 17 pain threshold, 21 pain intensity, 5 pain unpleasantness, 2 performance in pain and 1 bothersomeness study. Athletes demonstrated greater pain tolerance (g = .88 [95% confidence interval [CI] .65, .13]) and reported less pain intensity (g = -.80, [95% CI -1.13, -.47]) compared to controls; they also had higher pain threshold but with smaller effects (g = .41, [95% CI .08, .75]). Differences for unpleasantness did not reach statistical significance but the effects were large (g = -1.23 [95% CI -2.29, .18]). Two studies reported that performance in pain was better in contact athletes than non-athletes, and one concluded that athletes find pain less bothersome than controls. There were considerable inconsistencies in the methods employed that were reflected in the meta-analyses' findings. Sub-group analyses of tolerance and intensity were conducted between endurance, contact, and other athlete groups, but were not significant. The data suggest that athletic participation is associated with altered pain responses, but mechanisms remain unclear and more transparent methods are recommended.This study was registered on the PROSPERO site in January 2019 (ref ID: CRD42019119611). PERSPECTIVE: This review examined differences in pain outcomes (threshold, tolerance, intensity, unpleasantness, bothersomeness) and the effect of pain on performance, in athletes versus controls. Meta-analyses revealed athletes had higher threshold and tolerance and found pain less intense than controls; there was some evidence of differences in bothersomeness and performance.

Inter-rater reliability of the dynamic neuromuscular stabilization diaphragm tests among individuals with non-specific low back pain and neck pain

BACKGROUND

The Dynamic Neuromuscular Stabilization (DNS) diaphragm test and intra-abdominal pressure regulation test (IAPRT) are qualitative clinical tests that assess postural stability provided by the diaphragm.

OBJECTIVE

Evaluate the inter-rater reliability of the diaphragm test and IAPRT between an experienced and novice DNS clinician among individuals with non-specific low back pain (LBP) and neck pain.

METHODS

Forty-five participants with non-specific LBP and/or neck pain were assessed by an experienced and novice DNS physiotherapist in the diaphragm test and IAPRT, and scored on a visual analog scale (VAS) according to five different criteria.

RESULTS

Moderate reliability was noted when assessing LBP and neck pain patients in the diaphragm test and IAPRT (p < 0.001). Moderate reliability also existed when assessing only LBP (p < 0.001) or neck pain (p = 0.002, p = 0.009) independently. Patients with lower pain (NPRS score of 5 or < ) demonstrated lower intra-class correlation coefficients, yet still moderate reliability in the diaphragm test (p = 0.004) and IAPRT (p = 0.001). Patients with higher pain (NPRS score of 6 or > ) demonstrated greater intra-class correlation coefficients, with the diaphragm test resulting in good reliability (p < 0.001).

CONCLUSIONS

The diaphragm test and IAPRT demonstrate moderate reliability between an experienced and novice DNS clinician when evaluating LBP and neck pain patients, with a greater degree of reliability noted in patients suffering from higher reported pain.

Reduced Gray Matter Volume and Cortical Thickness in Patients With Small-Fiber Neuropathy

Small-fiber neuropathy (SFN) is defined by degeneration or dysfunction of peripheral sensory nerve endings. Central correlates have been identified on the level of gray matter volume (GMV) and cortical thickness (CT) changes. However, across SFN etiologies knowledge about a common structural brain signature is still lacking. Therefore, we recruited 26 SFN patients and 25 age- and sex-matched healthy controls to conduct voxel-based- and surface-based morphometry. Across all patients, we found reduced GMV in widespread frontal regions, left caudate, insula and superior parietal lobule. Surface-based morphometry analysis revealed reduced CT in the right precentral gyrus of SFN patients. In a region-based approach, patients had reduced GMV in the left caudate. Since pathogenic gain-of-function variants in voltage-gated sodium channels (Nav) have been associated with SFN pathophysiology, we explored brain morphological patterns in a homogenous subsample of patients carrying rare heterozygous missense variants. Whole brain- and region-based approaches revealed GMV reductions in the bilateral caudate for Nav variant carriers. Further research is needed to analyze the specific role of Nav variants for structural brain alterations. Together, we conclude that SFN patients have specific GMV and CT alterations, potentially forming potential new central biomarkers for this condition. Our results might help to better understand underlying or compensatory mechanisms of chronic pain perception in the future. PERSPECTIVE: This study reveals structural brain changes in small-fiber neuropathy (SFN) patients, particularly in frontal regions, caudate, insula, and parietal lobule. Notably, individuals with SFN and specific Nav variants exhibit bilateral caudate abnormalities. These findings may serve as potential central biomarkers for SFN and provide insights into chronic pain perception mechanisms.

The coexistence of diabetes, hypertension and obesity is associated with worse pain outcomes following exercise for osteoarthritis: A cohort study on 80,893 patients

OBJECTIVES

To investigate how the co-occurrence of diabetes, hypertension and overweight/obesity is associated with pain following an exercise intervention for knee and hip osteoarthritis (OA).

METHODS

Register-based cohort study. We included people from the Swedish Osteoarthritis Register who underwent education and exercise for knee or hip OA. Diabetes and hypertension were defined using medical records and dispensation of medication. Body Mass Index (BMI) was used to identify people with overweight (≥25 to <30), and obesity (≥30). We used linear mixed-effect models with patients nested into clinics to estimate the associations between the exposures and pain (Numeric Rating Scale 0-10), adjusting for age, sex, education, and physical activity.

RESULTS

We analysed 80,893 patients with knee or hip OA. The accumulation of metabolic conditions was associated with worse pain at baseline and follow-ups. When obesity, hypertension and diabetes coexisted, patients treated for knee OA reported more pain at baseline (adjusted mean pain difference 0.9 [95 %CI: 0.8; 1.0]), 3 months (1.0 [0.9; 1.1]) and 12 months (1.3 [1.1; 1.4]) compared to those without any of the conditions. Similar results were observed for patients treated for hip OA when obesity, hypertension and diabetes coexisted (baseline (0.7 [0.5; 0.8], 3 (0.8[0.6; 1.0]) and 12 months (1.1[0.8; 1.3]).

CONCLUSIONS

When diabetes, hypertension and obesity coexist with OA, patients not only experience heightened baseline pain compared to metabolically healthy individuals, but the disparity increases after an education and exercise intervention suggesting that a one-size-fits-all approach may be inadequate in addressing the complex interplay between metabolic health and OA.

Phenotyping of chronic pain in breast cancer survivors: an original study using the cancer pain phenotyping (CANPPHE) Network multidisciplinary international guidelines

PURPOSE

The primary aim of this cross-sectional study is to examine the prevalence of pain phenotypes in breast cancer survivors (BCS). A secondary aim entails examining whether health related quality of life differs between the main pain phenotypes in BCS.

METHODS

BCS who experienced chronic pain were asked to complete the numeric pain rating scale for pain, Margolis pain diagram, and short form 36 (SF-36). Following administration of questionnaires and quantitative sensory examinations were applied. To determine the prevalence of the predominant type of pain, a recently proposed classification system by the Cancer Pain Phenotyping (CANPPHE) Network was used.

RESULTS

Of the 86 female participants, 19 (22.09%) had dominant neuropathic pain, 18 (20.93%) had dominant nociceptive pain and 14 (16.28%) had dominant nociplastic pain. 35 participants (40.70%) were classified as having mixed pain. One-way ANOVA revealed a significant difference between the four pain groups for the SF-36 general health (F = 3.205, p = 0.027), social functioning (F = 4.093, p = 0.009), and pain (F = 3.603, p = 0.017) subscale scores.

CONCLUSION

This study found that pain in BCS was mostly of mixed phenotype, followed by predominantly neuropathic and nociplastic pain. Furthermore, it was found that, compared to BCS with predominant neuropathic and nociceptive pain, BCS with predominant nociplastic pain have lower health related quality of life in the areas of bodily pain and social functioning.

Dimensional versus standard 2-D laparoscopy for benign hysterectomy: A randomized clinical trial

OBJECTIVE

Our aim was to evaluate possible short and long-term benefits of 3-dimensional (3-D) compared to 2-dimensional (2-D) laparoscopy for benign hysterectomy. Primary outcomes were long-term quality of life and postoperative pain. Secondary outcomes were operative time, surgical complications, time to return to work and length of hospitalization.

STUDY DESIGN

A randomized controlled trial conducted at two Danish university hospitals. In each arm, 190 patients were needed for an alpha of 3.3 % and a power of 90 %. For various reasons, however, the study was prematurely terminated after including 97 patients. Patients were randomized to either 2-D (n = 48) or 3-D (n = 49) laparoscopy. A laparoscopic hysterectomy was performed. Quality of life was assessed by the Short Form Health Survey 36 (SF-36) questionnaire at the time of inclusion and 6 weeks postoperatively. Postoperative pain was assessed using a Numeric Rating Scale (NRS) and by monitoring the amount of analgesic consumption.

RESULTS

Out of the 97 randomized patients, 77 patients completed both SF-36 questionnaires. No significant differences in mental (p = 0.5) and physical status (p = 0.9) were found. The 2-D group had significantly higher pain-score registered in the post anesthesia care unit (PACU) (p = 0.004) and higher consumption of oral morphine equivalent dose (MEqD) (p = 0.003) than the 3-D group. This regardless a higher rate of minilaparotomies in the 2D (n = 7) than in the 3D (n = 1) group (p < 0.03). The 2-D group had also higher rate of Clavien-Dindo 2 (CD2) (n = 2) and Clavien-Dindo 3 (CD3) complications (n = 3) (p = 0.03) than 3-D (n = 0). The other secondary outcome parameters did not vary between groups.

CONCLUSIONS

The results are severely hampered by the premature termination of the study, as less than 25 percent of the patients were recruited. Thus, no firm conclusions can be drawn regarding the quality of life and many of the secondary outcomes, as the lack of difference may be attributed to a type 2 error. However, the significant differences in postoperative pain and in complication rates suggest a greater advantage of 3-D laparoscopy than originally expected. Despite the methodological problems, the current data deserve attention in a sparsely investigated field, emphasizing the urgent need for further studies.

Non-pharmacological interventions to prevent PICS in critically ill adult patients: a protocol for a systematic review and network meta-analysis

BACKGROUND

Postintensive care syndrome (PICS) is common in critically ill adults who were treated in the intensive care unit (ICU). Although comparative analyses between types of non-pharmacological measures and usual care to prevent PICS have been performed, it remains unclear which of these potential treatments is the most effective for prevention.

METHODS

To obtain the best evidence for non-pharmaceutical interventions in preventing PICS, a systematic review and Bayesian network meta-analyses (NMAs) will be conducted by searching nine electronic databases for randomized controlled trials (RCTs). Two reviewers will carefully screen the titles, abstracts, and full-text papers to identify and extract relevant data. Furthermore, the research team will meticulously check the bibliographic references of the selected studies and related reviews to discover any articles pertinent to this research. The primary focus of the study is to examine the prevalence and severity of PICS among critically ill patients admitted to the ICU. The additional outcomes encompass patient satisfaction and adverse effects related to the preventive intervention. The Cochrane Collaboration's risk-of-bias assessment tool will be utilized to evaluate the risk of bias in the included RCTs. To assess the efficacy of various preventative measures, traditional pairwise meta-analysis and Bayesian NMA will be used. To gauge the confidence in the evidence supporting the results, we will utilize the Confidence in NMA tool.

DISCUSSION

There are multiple non-pharmacological interventions available for preventing the occurrence and development of PICS. However, most approaches have only been directly compared to standard care, lacking comprehensive evidence and clinical balance. Although the most effective care methods are still unknown, our research will provide valuable evidence for further non-pharmacological interventions and clinical practices aimed at preventing PICS. The research is expected to offer useful data to help healthcare workers and those creating guidelines decide on the most effective path of action for preventing PICS in adult ICU patients.

Total knee arthroplasty following lateral closing-wedge high tibial osteotomy versus primary total knee arthroplasty: a propensity score matching study

BACKGROUND

The disparity in patient-reported outcomes between total knee arthroplasty (TKA) following high tibial osteotomy (HTO) and primary TKA has yet to be fully comprehended. This study aims to compare the patient-reported outcomes, radiological parameters and complication rates between TKA following HTO and primary TKA.

METHODS

Sixty-five patients who underwent TKA following lateral closing-wedge HTO were compared to a matched group of primary TKA at postoperative 6-months and 1-year. Between-group confounders of age, gender, smoking status, Body Mass index, preoperative Numeric Rating Scale (NRS) pain in rest, Knee injury and Osteoarthritis Outcome Score-Physical function Shortform (KOOS-PS), EuroQol five-dimensional (EQ-5D) overall health score, and Oxford Knee Score (OKS) were balanced by propensity score matching. Patient-reported outcome measures were NRS pain in rest, KOOS-PS, EQ-5D overall health score, and OKS. Radiological parameters were femorotibial angle, medial proximal tibial angle, anatomical lateral distal femoral angle, posterior tibial slope, and patellar height assessed by Insall-Salvati ratio. The complication rates of TKA were compared between the two groups. The HTO survival time, the choice of staple removal before or during TKA in patients who underwent TKA following HTO patients, and the rate of patellar resurfacing were assessed. The p value < 0.0125 indicates statistical significance after Bonferroni correction.

RESULTS

After propensity score matching, no significant between-group differences in the patient-reported outcome measures, radiographical parameters and complication rates were found (p > 0.0125). In the TKA following HTO group, with an average HTO survival time of 8.7 years, staples were removed before TKA in 46 patients (71%) and during TKA in 19 patients, and 11 cases (17%) had patella resurfacing. In the primary TKA group, 15 cases (23%) had patella resurfacing.

CONCLUSION

The short-term assessment of TKA following HTO indicates outcomes similar to primary TKA. A previous HTO does not impact the early results of subsequent TKA, suggesting that the previous HTO has minimal influence on TKA outcomes.

Exercise induced hypoalgesia during different intensities of a dynamic resistance exercise: A randomized controlled trial

INTRODUCTION

Exercise produces an immediate lessening of pain sensitivity (Exercise-Induced Hypoalgesia (EIH)) in healthy individuals at local and distant sites, possibly through a shared mechanism with conditioned pain modulation (CPM). Dynamic resistance exercise is a recommended type of exercise to reduce pain, yet limited research has examined the effects of intensity on EIH during this type of exercise. Therefore, the primary purpose of this study is to compare changes in PPT at a local and distant site during a leg extension exercise at a high intensity, a low intensity, or a quiet rest condition. A secondary purpose is to examine if CPM changes after each intervention. The final purpose is to examine if baseline pain sensitivity measures are correlated with response to each intervention.

METHODS

In a randomized controlled trial of 60 healthy participants, participants completed baseline pain sensitivity testing (heat pain threshold, temporal summation, a cold pressor test as measure of CPM) and were randomly assigned to complete a knee extension exercise at: 1) high intensity (75% of a 1 Repetition Maximum (RM), 2) low intensity (30% 1RM), or 3) Quiet Rest. PPT was measured between each set at a local (quadriceps) and distant (trapezius) site during the intervention. CPM was then repeated after the intervention. To test the first purpose of the study, a three-way ANOVA examined for time x site x intervention interaction effects. To examine for changes in CPM by group, a mixed-model ANOVA was performed. Finally, a Pearson Correlation examined the association between baseline pain sensitivity and response to each intervention.

RESULTS

Time x site x intervention interaction effects were not significant (F(5.3, 150.97) = 0.87, p = 0.51, partial eta2 = 0.03). CPM did not significantly change after the interventions (time x intervention F(1,38) = 0.81, p = 0.37, partial eta2 = 0.02. EIH effects at the quadriceps displayed a significant, positive moderate association with baseline HPT applied over the trapezius (r = 0.61, p<0.01) and TS (r = 0.46, p = 0.04).

DISCUSSION

In healthy participants, PPT and CPM did not significantly differ after a leg extension exercise performed at a high intensity, low intensity, or quiet rest condition. It is possible pre-intervention CPM testing with a noxious stimuli may have impaired inhibitory effects frequently observed during exercise but future research would need to examine this hypothesis.

Prevalence of frailty and pain in hospitalised cancer patients: implications for older adult care

A hospital-wide point prevalence study investigated frailty and pain in patients with a cancer-related admission. Modifiable factors associated with frailty in people with cancer were determined through logistic regression. Forty-eight patients (19%) with cancer-related admissions were 2.65 times more likely to be frail and 2.12 more likely to have moderate pain. Frailty and pain were highly prevalent among cancer-related admissions, reinforcing the need for frailty screening and importance of pain assessment for patients with cancer.

Long-term outcomes of extracorporeal shock wave therapy for acute Peyronie's disease: a 10-year retrospective analysis

The aim of this paper was to describe the long-term outcomes of extracorporeal shock wave therapy (ESWT) in patients with acute Peyronie'disease (PD). An observational retrospective study was conducted in men with acute PD who underwent ESWT between 2009-2013 at a single institution. ESWT protocol consisted of 1 session (3000 shock waves, 0.10-0.25 mJ/mm^2, 4-6 Hz) per week for 4 weeks. Penile pain was chosen as the primary outcome. Penile curvature angle, erectile function, and satisfaction with ESWT were selected as secondary long-term outcomes. A total of 194 patients were included. The mean follow-up duration after ESWT was 125.6 months. Mean penile curvature worsened significantly at 3 months (18.3 vs. 21.5 degrees; p = 0.023) and 12 months (21.5 vs. 28.6 degrees; p = 0.001) and stabilized over the long-term (28.6 vs. 28.8 degrees; p = 0.335). Mean penile pain improved significantly at 3 months (6.5 vs. 3.1 points; p < 0.001) and 12 months (3.1 vs. 1.0 points; p = 0.001), remaining stable over time (1.0 vs. 1.0 points; p = 0.074). The mean five-item version of the International Index of Erectile Function (IIEF-5) increased significantly at 3 months (14.5 vs. 17.9 points; p = 0.001), remaining stable at 12 months (17.9 vs. 18.5 points; p = 0.082), and deteriorating in the long-term (18.5 vs. 15.8 points; p = 0.003). A high satisfaction rate with ESWT was recorded at 3 months (92.3%), remaining similar at 12 months (91.2%) and over the long-term (90.2%). No new acute phase and low rate of PD surgery (4.1%) were recorded in the long-term analysis. In patients with acute PD, ESWT seems to be associated with early and persistent relief of penile pain, transient improvement in erectile function, no significant effect on penile curvature, and a high rate of patient satisfaction constant over time.

The severity of second-degree perineal tears and perineal pain during three months postpartum: A prospective cohort study

BACKGROUND

Second-degree perineal tears are common and can vary widely in the extent of tissue trauma. Therefore, a better understanding of perineal pain based on tissue trauma severity in second-degree tears is needed.

AIM

The primary aim of this study was to assess differences in perineal pain according to the severity of perineal tears, with a focus on subcategories of second-degree tears, during the first three months postpartum. The secondary aim was to assess the use of pain medication and breastfeeding patterns according to the severity of the second-degree tears.

METHODS

In this observational cohort study, nulli- and multiparous women with singleton pregnancies were included during pregnancy. After birth, perineal tears were classified using the latest international classification system. In addition, second-degree tears were subcategorised according to percentage of damage to the perineum (<50 %=2A,>50 % but less than entire perineum=2B, affecting entire perineum, anal sphincter not involved=2C). Perineal pain, use of pain medication and breastfeeding patterns were assessed during a phone interview seven to ten days postpartum and through an electronic questionnaire three months postpartum.

FINDINGS

Out of 880 vaginal births, 852 participants completed the phone interview and 715 answered the electronic questionnaire. During the first three months postpartum, women with 2C-tears reported statistically significantly higher pain scores and more frequent use of pain medication compared to women with 2A-tears. There was no statistically significant difference between the number of participants not breastfeeding between second-degree tear subcategories.

CONCLUSION

Women with 2C-tears reported higher perineal pain scores and more use of pain medication compared to those with less severe tears during three months postpartum.

Health-related quality of life following trauma: Prevalence of problems and factors associated with six-month outcomes in a New Zealand cohort

Injury is a leading cause of health loss in Aotearoa me Te Waipounamu (New Zealand; NZ). The NZ Trauma Registry was established in 2015 to monitor outcomes in those experiencing severe injury and to identify ways of improving the quality of care for these patients. Few NZ studies have assessed outcomes in trauma patients using patient-reported outcome measures (PROMs) despite increasing recognition that the impacts of injury are better understood through PROMs. Our aim was to estimate the prevalence of self-reported problems with health-related quality of life (HRQoL) outcomes six months post-injury, and identify factors associated with these, in a cohort of Māori (the Indigenous population of NZ) and non-Māori individuals who had experienced major trauma. HRQoL outcomes were measured according to the five dimensions of the EQ-5D-5L. This information, along with sociodemographic data, was collected via structured telephone interviews. Participants (n = 870), aged 16 years or more, were recruited following admission to a trauma hospital in one of three (of NZ's four) trauma regions. Multivariable models were developed using modified Poisson Regression to identify factors associated with outcomes for both Māori and non-Māori patients. The prevalence and severity of problems across each of the five EQ-5D-5L dimensions was similar for Māori and non-Māori except for Anxiety/Depression. The prevalence and severity of problems with Anxiety/Depression was greater for Māori. Factors associated with HRQoL problems at six-months were also largely similar for each cohort. Those commonly associated with outcomes were age, hospital length of stay, adequacy of household income, and participants' expectations regarding recovery from injury. Further research examining recovery expectations in trauma patients to determine which factors contribute to formulating recovery expectations, and the potential impact of recovery expectations on treatment and rehabilitation, would be of value. Should expectations, at least in part, influence HRQoL outcomes, then routinely collecting data on patients' recovery expectations, adequacy of household income and potential barriers to treatment and rehabilitation, could help inform post-hospital treatment plans, and identify those who may require additional support following discharge from hospital.

How Does the Breastfeeding Environment Affect Satisfaction? A Scale Development Study

BACKGROUND

Women need a safe and comfortable environment to breastfeed their babies. The quality of breastfeeding environments in social areas is important for women's breastfeeding satisfaction.

AIM

The aim of this study was to develop a measurement tool for the evaluation of breastfeeding environments and to examine the impact of the quality of breastfeeding environments in social areas on breastfeeding satisfaction.

METHOD

The first phase of the study was conducted in methodological design and the second phase in cross-sectional design. The draft scale was applied to 365 women who had breastfeeding experiences in social environments during the postpartum 6 months-3 years period. In the first stage, scale development analyses were applied. In the second stage, the developed scale was applied to 255 women. Frequency, percentage, Cronbach's α coefficient, and correlation analysis were used in the analysis of the data.

RESULTS

The Ideal Breastfeeding Environment Assessment Scale, consisting of 23 items and four subdimensions, was obtained in the study. As a result of the application of the scale in the second stage, the mean score of the breastfeeding environments evaluated by the women was 23.43 ± 8.36. A statistically significant moderate-weak correlation was found between the ideality of breastfeeding environments and the satisfaction levels of women (p < .001).

CONCLUSION

It was determined that the developed scale is a valid and reliable measurement tool that can be used to evaluate breastfeeding environments. As the quality of breastfeeding environments increases, women's breastfeeding satisfaction increases.

Hip chronic pain: ultrasound guided ablation of anterior articular branches plus posterior neurolysis of the nerve to the quadratus femoris versus the alone anterior approach-a retrospective observational study

INTRODUCTION

Chronic hip pain is a common painful condition in the elderly population. A mini invasive technique that is increasingly being considered for management of CHP is the percutaneous denervation of hip articular branches via radiofrequency ablation. We described a new ultrasound-guided technique based on the combination of 90° ultrasound-guided anterior radiofrequency ablation of the articular branches of femoral nerve, accessory obturator nerve and obturator nerve for anterior hip, combined with 90° ultrasound-guided ablation of the articular branches of the nerve of the quadratus femoris for posterior pericapsular neurolysis of the hip.

MATERIAL E METHODS

We retrospectively analyzed the medical records of patients from September 2022 to September 2023 treated for chronic hip pain in the ambulatory of Pain Management, identifying 22 patients who underwent ultrasound guided radiofrequency denervation of anterior hip articular branches alone (Group B); and 22 patients in which was also applied a radiofrequency denervation of the posterior articular branches, in addition to the anterior denervation (Group A). We analysed the pain intensity of both groups measured with numeric rating scale.

RESULT

The combined anterior plus posterior approach ensured that the results obtained were maintained 6 months after the procedure (T3) with excellent pain control and an average NRS of 1455 for group A. While for the group B, with the anterior approach alone, the NRS at six months showed an upward trend with an average NRS of 3818. The dual approach is more effective in pain relief at 6 months with a statistically significant difference in NRS values (p < 0.001).

CONCLUSION

This retrospective observational study highlighted the greater impact of the double approach (anterior plus posterior) in the denervation of the hip joint, compared to anterior neurolysis alone.

Effects of short-term upper extremity exercise training in office workers during COVID-19 restrictions: A randomized controlled trial

BACKGROUND

During COVID-19 pandemic, physical inactivity and inactivity-related health problems have deepened in many individuals, including office workers. It is not yet known whether there are exercise programs through telerehabilitation that will provide rapid relief in a short time in office workers who apply part or full-time teleworking system.

OBJECTIVE

To comparatively investigate influences of short-term upper extremity exercise trainings (UEET) on pain, musculoskeletal discomforts (MSD), physical activity (PA), mood, and quality of life (QOL) in office workers during COVID-19 restrictions.

METHODS

Thirty office workers were divided into exercise (EG) (UEET and walking advice) and control (CG) (walking advice) groups. The UEET was applied for at least 20-40 minutes/day, 5-7 days/week for a one week between February 2022 and June 2022. Office workers' pain, MSD, PA level, mood and QOL were measured.

RESULTS

Baseline characteristics of groups (EG: 37.8±7.04 years, CG: 41.6±7.97 years) were similar (p >  0.05). Following UEET, scores of office workers in EG on total step count, vigorous PA, moderate-intensity PA, walking, total PA, physical functioning, and body pain subscales of QOL significantly increased compared to scores of office workers in CG, while scores on neck, back and hip discomforts and anxiety and depression significantly decreased (p <  0.05).

CONCLUSIONS

One-week UEET and walking advice can improve office workers' daily step counts, MSD, PA levels, mood, and QOL. Office workers who have a busy work schedule may do these UEET and walking exercises in break times to relieve perception of discomfort.

Opioid use in cancer patients compared with noncancer pain patients in a veteran population

BACKGROUND

Opioid safety initiatives may secondarily impact opioid prescribing and pain outcomes for cancer care.

METHODS

We reviewed electronic health record data at a tertiary Veterans Affairs system (VA Palo Alto) for all patients from 2015 to 2021. We collected outpatient Schedule II opioid prescriptions data and calculated morphine milligram equivalents (MMEs) using Centers for Disease Control and Prevention conversion formulas. To determine the clinical impact of changes in opioid prescription, we used the highest level of pain reported by each patient on the 0-to-10 Numeric Rating Scale in each year, categorized into mild (0-3), moderate (4-6), and severe (7 and above).

RESULTS

Among 89 569 patients, 9073 had a cancer diagnosis. Cancer patients were almost twice as likely to have an opioid prescription compared with noncancer patients (69.0% vs 36.7%, respectively). The proportion of patients who received an opioid prescription decreased from 27.1% to 18.1% (trend P < .01) in cancer patients and from 17.0% to 10.2% in noncancer patients (trend P < .01). Cancer and noncancer patients had similar declines of MMEs per year between 2015 and 2019, but the decline was more rapid for cancer patients (1462.5 to 946.4, 35.3%) compared with noncancer patients (1315.6 to 927.7, 29.5%) from 2019 to 2021. During the study period, the proportion of noncancer patients who experienced severe pain was almost unchanged, whereas it increased among cancer patients, reaching a significantly higher rate than among noncancer patients in 2021 (31.9% vs 27.4%, P < .01).

CONCLUSIONS

Our findings suggest potential unintended consequences for cancer care because of efforts to manage opioid-related risks.

Effectiveness analysis of herbal medicine for gastroesophageal reflux disease: A retrospective study

This study aimed to identify the clinical features of gastroesophageal reflux disease (GERD) in primary clinics and the effectiveness and safety of herbal medicine (HM). Thirty-five patients with gastroesophageal-reflux symptom who visited the 16 Korean medicine (KM) primary clinics from June 2022 to October 2022 were included in the study. We retrospectively analyzed the charts of 35 patients and collected clinical characteristics, HM, and outcome variables such as the numerical rating scale, gastroesophageal reflux disease questionnaire, frequency scale for symptoms of gastroesophageal reflux disease, Euro-Quality Of Life-5 Dimension, and adverse events. Of the 35 patients, 12 (34.3%) were men, and the average age of all patients was 47.0 ± 14.3 years. HM was prescribed for all 35 patients; Pinelliae Tuber (n = 31, 88.57%), Zingiberis Rhizoma Recens (n = 30, 85.71%), and Poria Sclerotium (n = 28, 80%) were the most prescribed herbs. All scores including numerical rating scale, frequency scale for symptoms of gastroesophageal reflux disease, gastroesophageal reflux disease questionnaire, and Euro-Quality Of Life-5 Dimension after 30 and 60 days from baselines showed significant improvement, and there were only a few adverse events. This study supports the effectiveness and safety of HM in reducing GERD symptoms in primary Korean medicine clinics. The most frequently used herbs may play significant roles in GERD symptom management.

Insomnia, Fatigue, Bladder Disorders and Mood Disorders among Polish Patients with Multiple Sclerosis: Cross-Sectional Study

BACKGROUND

To investigate the prevalence of sleep disorders in patients with multiple sclerosis (PwMS) in comparison to healthy controls (HCs), we aim to explore the correlation between sleep disorders and fatigue, bladder dysfunction, mood disorders in PwMS.

METHODS

This study involved 175 PwMS and 115 HCs. We conducted a self-administered survey using questionnaires (the authors' questionnaire, the Athens Insomnia Scale (AIS), the Epworth Sleepiness Scale (ESS), the Modified Fatigue Impact Scale (MFIS), the Fatigue Severity Scale (FSS), the Hospital Anxiety and Depression Scale (HADS), and the Numerical Rating Scale (NRS). The neurological disability was determined using Expanded Disability Status Scale. Logistic regression was used to estimate odds ratios (ORs) with 95% confidence intervals (CIs).

RESULTS

According to AIS, insomnia was found in 20.6% of PwMS compared to 9.6% of HCs (p < 0.001). Comparing female and male PwMS, we observed that insomnia was more prevalent among female PwMS (25.95% vs. 4.55%, respectively, p < 0.05). Excessive daytime sleepiness was more prevalent in female PwMS (p < 0.05). Female PwMS were more fatigue based on the FSS and the MFIS (p < 0.05). Bladder disorders were observed in 39.43% of PwMS and were significantly linked to MS (p < 0.001). Sleep disturbances were associated with anxiety disorders (OR = 0.22, 95% CI 0.12-0.32 p < 0.001), bladder dysfunction (OR = 0.52 95% CI 0.16-0.87 p < 0.05), and female gender (OR = 0.49, 95% CI 0.037-0.94 p < 0.05).

CONCLUSIONS

Insomnia is prevalent among PwMS. Our study revealed independent predictors of sleep disturbances among PwMS: female gender, bladder disorders, and anxiety.

Analysis of the factors influencing moderate to poor performance status in patients with cancer after chemotherapy: a cross-sectional study comparing three models

There are no models for assessing the factors that determine moderate to poor performance status in patients with cancer after chemotherapy. This study investigated the influencing factors and identified the best model for predicting moderate-poor performance status. A convenience sampling method was used. Demographic and clinical data and evaluation results for fatigue, pain, quality of life and Eastern Cooperative Oncology Group status were collected three days after the end of chemotherapy. Decision tree, random forest and logistic regression models were constructed. Ninety-four subjects in the case group had moderate to poor performance status, and 365 subjects in the control group had no or mild activity disorders. The random forest model was the most accurate model. Physical function, total protein, general quality of life within one week before chemotherapy, hemoglobin, pain symptoms and globulin were the main factors. Total protein and hemoglobin levels reflect nutritional status, and globulin levels are an index of liver function. Therefore, physical function, nutritional status, general quality of life and pain symptoms within one week before chemotherapy and liver function can be used to predict moderate-poor performance status. Nurses should pay more attention to patients with poor physical function, poor nutritional status, lower quality of life and pain symptoms after chemotherapy.

Technical Challenges for Laryngeal Electromyography

BACKGROUND/OBJECTIVE

Laryngeal electromyography (LEMG) is a useful diagnostic test in the evaluation of vocal fold paralysis (VFP). This study investigates factors that can make LEMG challenging to perform.

METHODS

Patients with subacute unilateral VFP presented for LEMG were prospectively enrolled. Demographic data including BMI, previous neck surgery, and anatomic factors were collected. Patient-reported pain related to the procedure was recorded on a visual analogue scale (VAS). Electromyographer and otolaryngologist recorded a consensus rating of the perceived difficulty in performing the test and confidence in using the results for clinical decision-making.

RESULTS

A total of 111 patients (56.8% female) were enrolled between August 2015 and August 2018. The mean age was 55 ± 14 years, and the average body mass index (BMI) was 28.5 ± 6.4. The mean patient-reported VAS score for pain was 35 ± 24. Notably, 31.2% of the tests were considered "very easy," 32.1% were considered "mildly challenging" and 23.9% and 12.8% were considered "moderately challenging" and "extremely challenging," respectively, by the clinicians. Common factors affecting LEMG difficulty included poorly palpable surface anatomy (50.5%) and patient intolerance (15.6%). Clinicians felt confident in 76.1% of the test findings. Bivariate analyses showed that prior neck surgery is associated with elevated VAS (p = 0.02), but clinician-perceived difficulty of performing the test is not associated with elevated VAS scores (p = 0.55).

CONCLUSIONS

Majority of LEMG tests are well tolerated by patients. Physicians reported more confidence using LEMG for clinical decision-making when the test was easier to perform. Difficult surface anatomy and patient intolerance affects clinician confidence in integrating the test results with clinical care.

Characteristics and clinical challenges in patients with substance use disorder in palliative care-experience from a tertiary center in a high-income country

BACKGROUND

Access to palliative care is often limited for challenging and vulnerable groups, including persons with substance use disorders. However, with optimized healthcare options and liberal substitution policies, this patient group is likely to increase over the upcoming years, and comorbidities will also influence the need for palliative support. Here, we aim at analyzing characteristics and specific challenges associated with substance use disorders (SUD) in palliative care.

METHODS

We retrospectively reviewed all patients diagnosed with substance use disorder that were treated at our Competence Center Palliative Care within the University Hospital Zurich, Switzerland between 2015 and 2021. Patient characteristics, including age, gender, duration of hospitalization, as well as specific metrics like body mass index, distinct palliative care assessment scores, and in-hospital opioid consumption were retrieved from the electronic patient files. Demographics and clinical data were analyzed by descriptive statistics, and compared to those of a control group of palliative care patients without SUD. An opioid calculator was used to standardize opioid intake based on morphine equivalents for meaningful comparisons.

RESULTS

The primary characteristics revealed that the majority of individuals were single (56%), had no children (83%), lived alone (39%), and were either unemployed or recipients of a disability pension (in total 50%). Nicotine (89%), opioids (67%), and alcohol (67%) were the most used substances. We identified various comorbidities including psychiatric illnesses alongside SUD (56%), hepatitis A, B, or C (33%), and HIV infection (17%). Patients with SUD were significantly younger (p < 0.5), predominantly male (p < 0.05), and reported a higher prevalence of pain (p < 0.5) compared to the standard cohort of palliative patients. Regarding the challenges most frequently reported by healthcare practitioners, non-compliance, multimorbidity, challenging communication, biographical trauma, lack of social support, and unstable housing situations played a key role.

CONCLUSION

Patients with SUD represent a complex and vulnerable group dealing with multiple comorbidities that profoundly affect both their physical and psychological well-being. Understanding their unique characteristics is pivotal in providing precise and suitable palliative care.

Natural History of Mandibular Function in Spinal Muscular Atrophy Types 2 and 3

Background

Hereditary proximal spinal muscular atrophy (SMA) is characterized by abnormal alpha motor neuron function in brainstem and spinal cord. Bulbar dysfunction, including limited mouth opening, is present in the majority of patients with SMA but it is unknown if and how these problems change during disease course.

Objective

In this prospective, observational, longitudinal natural history study we aimed to study bulbar dysfunction in patients with SMA types 2 and 3.

Methods

We included 44 patients with SMA types 2 and 3 (mean age was 33.6 (95% CI 28.4;38.9) and re-examined them after on average 4 years. None were treated with SMN-modulating treatments before or during the course of this study. Longitudinal assessments included a questionnaire on mandibular and bulbar function, the Mandibular Function Impairment Questionnaire (MFIQ), and a clinical examination of masticatory performance, maximum voluntary bite force, and mandibular movements including the active maximal mouth opening.

Results

We found significant higher MFIQ scores and a significant decrease of all mandibular movements in patients with SMA type 2 (p < 0.001), but not in SMA type 3. Masticatory performance and maximum voluntary bite force did not change significantly. Mean reduction of active maximal mouth opening at follow-up was 3.5 mm in SMA type 2 (95% CI: 2.3; 4.7, p < 0.001). SMA type 2 was an independent predictor for a more severe reduction of the mouth opening (β= -2.0 mm (95% CI: -3.8; -0.1, p = 0.043)).

Conclusions

Bulbar functions such as mandibular mobility and active maximum mouth opening decrease significantly over the course of four years in patients with SMA type 2.

The effects of virtual reality environmental enrichments on craving to food in healthy volunteers

RATIONALE

Environmental enrichment (EE) is a non-pharmacological approach that has been shown to be effective in reducing food-taking in rats. Studies in human volunteers are still in their infancy, given the difficulty to translate the complexity of EE in clinical practice. Virtual reality (VR) is a promising methodological approach, but no study has yet applied it to model and test EE in humans.

OBJECTIVES

The present study is the first to assess the effects of virtual EE on craving for palatable food.

METHODS

Eighty-one healthy volunteers (43 women) were divided into three groups: (i) exposure to a virtual EE (VR-EE), (ii) exposure to a virtual neutral environment (VR-NoEE), and (iii) without exposure to VR (No VR). Craving for palatable food at basal level and evoked by neutral and palatable food images was assessed before and after the VR simulation. Behavior during VR exposure and subjective measures related to the experience were also collected.

RESULTS

VR-EE group showed a significantly greater decrease in pre-post craving difference compared to No VR for all assessments and at basal level compared to VR-NoEE. Interestingly, an inverse correlation between craving and deambulation in the VR simulation emerged in VR-EE group only.

CONCLUSIONS

The study highlighted the feasibility of exposing human subjects to an EE as a virtual simulation. Virtual EE induced effects on basal craving for food that suggest the potential for further improvements of the protocol to extend its efficacy to palatable food cues.

Medium-term Results After Femoral Head Resection and Subtrochanteric Valgus Osteotomy in Children and Adolescents With Neuromuscular Disorders

BACKGROUND

Various salvage surgical procedures for painful hip dislocation in adolescent patients with cerebral palsy exist. To date, no significant differences among these surgical techniques have been described. In our institution the McHale procedure is the standard of care for painful chronically dislocated hips with or without deformity of the femoral head in patients with cerebral palsy. This study focuses on mid-term results after surgical treatment.

METHODS

Surgical reports and patient charts were analyzed retrospectively. All x-rays were evaluated and migration of the proximal femur and heterotopic ossification according to Brooker were recorded. In addition, we conducted a telephone interview with the caretakers with special reference to pain preoperatively and postoperatively and after implant removal, sitting tolerance, range of motion, mobility, quality of life, and personal hygiene.

RESULTS

Fifty-two patients (65 hips) with a mean age of 13.5 ± 3.6 years (range: 4 to -20 y) were included. Mean surgery time was 178.4 ± 63.4 minutes (range: 45 to 380 min) and mean follow-up was 45.17 ± 30.6 months (range: 12 to 204 mo). A significant difference between preoperative and postoperative pain levels was found, P <0.001. Personal hygiene ( P =0.02) and quality of life ( P =0.013) improved significantly. Eighty-five percent of the caregivers would have the surgery performed on their child again and 81% of the caregivers would recommend the surgery to others. The removal of implants leads to a significant improvement in pain ( P =0.011). A total of 22 complications in 65 McHale procedures (33.9%) were related to the procedures.

CONCLUSIONS

A significant reduction in pain and a significant improvement of hygiene as well as quality of life can be achieved with the McHale procedure in painful chronically dislocated hips in patients with cerebral palsy. Overall, the procedure is predominantly experienced as helpful by the caregivers and recommended to others. The removal of the implants improves pain significantly, but complications may occur in one third of the patients.

Pre-Diagnosis Pain in Patients With Pancreatic Cancer Signals the Need for Aggressive Symptom Management

OBJECTIVE

This study assessed the impact of pancreatic cancer (PC) pain on associated symptoms, activities, and resource utilization from 2016 to 2020 in an online patient registry.

PATIENTS AND METHODS

Responses from PC patient volunteers (N = 1978) were analyzed from online surveys in a cross-sectional study. Comparisons were performed between PC patient groups reporting, (1) the presence vs. absence of pre-diagnosis PC pain, (2) high (4-8) vs. low (0-3) pain intensity scores on an 11-point numerical rating scale (NRS), and (3) year of PC diagnosis (2010-2020). Descriptive statistics and all bivariate analyses were performed using Chi-square or Fisher's Exact tests.

RESULTS

PC pain was the most frequently reported pre-diagnosis symptom (62%). Pre-diagnostic PC pain was reported more frequently by women, those with a younger age at diagnosis, and those with PC that spread to the liver and peritoneum. Those with pre-diagnostic PC pain vs. those without reported higher pain intensities (2.64 ± 2.54 vs.1.56 ± 2.01 NRS mean ± SD, respectively, P = .0039); increased frequencies of post-diagnosis symptoms of cramping after meals, feelings of indigestion, and weight loss (P = .02-.0001); and increased resource utilization in PC pain management: (ER visits N = 86 vs. N = 6, P = .018 and analgesic prescriptions, P < .03). The frequency of high pain intensity scores was not decreased over a recent 11-year span.

CONCLUSIONS

PC pain continues to be a prominent PC symptom. Patients reporting pre-diagnosis PC pain experience increased GI metastasis, symptoms burden, and are often undertreated. Its mitigation may require novel treatments, more resources dedicated to ongoing pain management and surveillance to improve outcomes.

Perceived Injustice in Cancer Survivors: Population-Specific Cut-Off Score and Relations with Personal Factors, Symptoms and Quality of Life-A Cross-Sectional Study

Fatigue and pain are the most common side effects impacting quality of life (QoL) in cancer survivors. Recent insights have shown that perceived injustice (PI) can play a substantial role in these side effects, but research on cancer survivors is scarce. Furthermore, guidelines for recognizing clinically relevant levels of PI in cancer survivors are missing. The aims of this study are to provide a clinically relevant cut-off for PI and to explore relationships between personal characteristics, symptoms, and QoL with PI. This multicenter, cross-sectional study uses the Injustice Experience Questionnaire (IEQ), Numeric Pain Rating Scale (NPRS), Patient-Specific Complaints (PSC), Multidimensional Fatigue Index (MFI), and European Organization for Research and Treatment of Cancer QoL Questionnaire-C30 (EORTC-QLQ-C30). A clinical cut-off for PI was identified based on the 75th percentile of IEQ scores. Univariate and multivariate regressions explored the relationship between PI and personal characteristics (sex, age, cancer type, treatment type), symptoms (pain intensity, fatigue), and QoL (daily activity complaints, cancer-related QoL). Cancer survivors (n = 121) were included, and a cut-off of 20 was identified. Significant indirect associations were found between chemotherapy, NPRS, PSC, MFI, and EORTC-QLQ-C30 with PI. In the multivariate model, only MFI (B = 0.205; 95% CI: 0.125-0.018) and age (B = 0.086; 95% CI: -0.191-0.285) maintained a significant association with PI.

Quadratus lumborum block for postoperative pain management in patients undergoing total hip arthroplasty: a systematic review and meta-analysis

BACKGROUND

The use of quadratus lumborum nerve blocks (QLB) for pain control following elective total hip arthroplasty (THA) has increased substantially in recent years. The objective of this systematic review and meta-analysis was to compare outcomes from randomised controlled trials (RCTs) utilising QLBs following elective THA.

METHODS

MEDLINE, EMBASE, and Cochrane databases were searched for RCTs perioperative QLBs for THA. Quantitative synthesis was conducted for pain scores, opioid consumption and adverse events.

RESULTS

A total of 7 RCTs with 429 patients undergoing THA were included. No differences in pain scores were demonstrated between QLBs and control interventions. Subgroup analysis demonstrated no differences between QLBs and sham procedures or active comparators. No differences in postoperative opioid consumption between QLB and control interventions was found. In trials reporting adverse events, they were rare and similar between groups. Overall, the certainty of the evidence was graded as low or very low.

CONCLUSIONS

The current literature suggests that a QLB for THA does not reduce pain or opioid consumption compared to sham or active comparators.

Cold Plasma Therapy in Chronic Wounds-A Multicenter, Randomized Controlled Clinical Trial (Plasma on Chronic Wounds for Epidermal Regeneration Study): Preliminary Results

Chronic wounds (CWs) pose a significant health challenge in clinical practice. Standard wound therapy (SWT) is currently considered the gold standard. However, recent evidence suggests that cold plasma therapy (CPT) holds promise for improving CWs. In light of this, the POWER study was conducted as a multicenter, randomized clinical trial to investigate the effect of large-area plasma application compared with SWT in patients with chronic, non-healing arterial or venous wounds on the lower leg. To analyze the interim results, we employed a comprehensive range of statistical tests, including both parametric and non-parametric methods, as well as GLS model regression and an ordinal mixed model. Our findings clearly demonstrate that CPT therapy significantly accelerates wound closure compared with SWT. In fact, complete wound closure was exclusively observed in the CPT group during the intervention period. Additionally, the CPT group required significantly less antibiotic therapy (4%) compared with the SWT group (23%). Furthermore, CPT led to a significant reduction in wound pain and improved quality of life compared with SWT. In conclusion, the study highlights that the combination of CPT and SWT surpasses monotherapy with SWT alone.

Transcutaneous auricular branch vagal nerve stimulation as a non-invasive add-on therapeutic approach for pain in systemic sclerosis

OBJECTIVE

Systemic sclerosis (SSc) is an autoimmune disease with health-related quality of life (HRQoL) high impairment. Pain is of paramount importance to be targeted by therapeutical approaches. Our study aim was to perform an add-on device-based non-invasive neuromodulatory treatment through transcutaneous auricular vagal nerve stimulation (tVNS) in patients with SSc, assessing its effects on pain as primary endpoint and on inflammation, cardiovascular autonomic control and HRQoL.

METHODS

Thirty-two patients with SSc were enrolled based on reported pain assessed through Numeric Rating Scale (NRS). Twenty-one (90% with limited cutaneous SSc) completed a randomised, cross-over, patient-blind trial, in which interventional and active control were used in random order for 4 weeks, interspersed with 4 weeks washout. NRS, Patient-Reported Outcomes Measurement Information System-29 (PROMIS-29) Item4 for pain interference, heart rate variability (HRV), serum cytokines and HRQoL questionnaires (Health Assessment Questionnaire, Patient Health Questionnaire-9, University of California, Los Angeles Gastrointestinal Tract, Pittsburgh Sleep Quality Index) were assessed at baseline, at T1 (after 1 month of tVNS or active control), at T2 (after washout) and at T3 (after 1 month of active control or tVNS). T-test for paired data and Wilcoxon signed-rank test for non-normally distributed parameters were performed to compare the effect of tVNS and active control.

RESULTS

NRS pain was significantly reduced by tVNS and not by active control (Mean±SD: -27.7%±21.3% vs -7.7%±26.3%, p=0.002). Interleukin-6 was downregulated in tVNS versus active control (p=0.029). No significant differences were observed in tVNS versus active control for PROMIS-29 Item4, QoL scales and HRV with both spectral and symbolic analyses.

CONCLUSION

tVNS demonstrated to be a safe and non-invasive add-on tool to reduce pain in SSc.

Post-operative pain following percutaneous nephrolithotripsy- clinical correlates

OBJECTIVES

Management of postoperative pain following percutaneous nephrolithotripsy (PCNL) is a significant goal. We sought to identify risk factors and clinical correlates of postoperative pain in order to improve perioperative management and patient satisfaction.

MATERIALS AND METHODS

A single-center, retrospective analysis, from a prospectively maintained database, of all consecutive patients who underwent PCNL for renal calculi between January 2011 and August 2018. Postoperative pain was assessed using the visual analog scale (VAS) and analgesic use. We considered VAS score above 4 as meaningful. Pain management was standardized according to patirnt reported VAS scores. Multivariable logistic regression was performed to identify risk factors and clinical correlates.

RESULTS

A total of 496 patients were analyzed. Younger age was associated with VAS above 4 on the operative day and the first postoperative following PCNL (p = 0.003 and p < 0.001, respectively). Female gender was associated with VAS above 4 in the first 2 days following the operation (p < 0.001).

CONCLUSIONS

Younger age and female gender would most likely benefit from pre-emptive improved pain management protocols following PCNL.

The Usefulness of a Three-Microneedle Device for Indocyanine Green Fluorescence Lymphography

Background: Indocyanine green (ICG) fluorescence lymphography is widely used to diagnose lymphedema. There is little consensus on the appropriate injection method for ICG fluorescence lymphangiography. We used a three-microneedle device (TMD) for skin injection of ICG solution and investigated its usefulness. Methods and Results: Thirty healthy volunteers were injected with ICG solution using a 27-gauge (27G) needle in one foot and a TMD in the other foot. Injection-related pain was evaluated using the Numerical Rating Scale (NRS) and Face Rating Scale (FRS). The skin depth of the injected ICG solution was evaluated by injecting the solution into the skin of amputated lower limbs using a 27G needle or TMD using ICG fluorescence microscopy. The median and interquartile range of the NRS scores was 3 (3-4) and 2 (2-4) in the 27G needle and TMD groups, respectively; that of the FRS scores was 2 (2-3) and 2 (1-2) in the 27G needle and TMD groups, respectively. Injection-related pain was significantly lower with the TMD than with the 27G needle. The lymphatic vessels were similarly visible using both needles. The depth of the ICG solution varied for each injection with a 27G needle (400-1200 μm) and was consistent at ∼300-700 μm below the skin surface using the TMD. Injection depth was significantly different between the 27G needle and the TMD. Conclusions: Injection-related pain decreased using the TMD, and ICG solution depth was consistent on fluorescence lymphography. A TMD may be useful for ICG fluorescence lymphography.

Randomised controlled trials of non-pharmacological interventions to improve patient-reported outcomes of colonoscopy: a scoping review

BACKGROUND AND AIMS

Non-pharmacological interventions to improve patient-reported outcomes of colonoscopy may be effective at mitigating negative experiences and perceptions of the procedure, but research to characterise the extent and features of studies of these interventions is limited.

METHODS

We conducted a scoping review searching multiple databases for peer-reviewed publications of randomised controlled trials conducted in adults investigating a non-pharmacological intervention to improve patient-reported outcomes of colonoscopy. Study characteristics were tabulated and summarised narratively and graphically.

RESULTS

We screened 5939 citations and 962 full texts, and included 245 publications from 39 countries published between 1992 and 2022. Of these, 80.8% were full publications and 19.2% were abstracts. Of the 41.9% of studies reporting funding sources, 11.4% were unfunded. The most common interventions were carbon dioxide and/or water insufflation methods (33.9%), complementary and alternative medicines (eg, acupuncture) (20.0%), and colonoscope technology (eg, magnetic scope guide) (21.6%). Pain was as an outcome across 82.0% of studies. Studies most often used a patient-reported outcome examining patient experience during the procedure (60.0%), but 42.9% of studies included an outcome without specifying the time that the patient experienced the outcome. Most intraprocedural patient-reported outcomes were measured retrospectively rather than contemporaneously, although studies varied in terms of when outcomes were assessed.

CONCLUSION

Research on non-pharmacological interventions to improve patient-reported outcomes of colonoscopy is unevenly distributed across types of intervention and features high variation in study design and reporting, in particular around outcomes. Future research efforts into non-pharmacological interventions to improve patient-reported outcomes of colonoscopy should be directed at underinvestigated interventions and developing consensus-based guidelines for study design, with particular attention to how and when outcomes are experienced and measured.

Efficacy of Subchondroplasty in the Treatment of Pain Associated With Bone Marrow Lesions in the Osteoarthritic Knee

Background

Bone marrow lesions (BMLs) are common subchondral defects revealed by magnetic resonance imaging (MRI) in patients with osteoarthritis, often associated with pain and functional limitation. Subchondroplasty (SCP) is a relatively new technique in which bone substitute material (BSM) is injected inside BML areas to provide structural support to the subchondral bone, preventing its collapse and reducing pain.

Purpose/Hypothesis

The purpose of this study was to characterize changes in pain, functional and radiological outcomes, conversion to knee replacement, and complications after SCP. We hypothesized that ≥70% of patients would achieve a reduction in pain of ≥4 points on a numeric rating scale (NRS) at a 6-month follow-up after SCP.

Study Design

Case series; Level of evidence, 4.

Methods

Patients with symptomatic knee BMLs who underwent SCP were prospectively evaluated preoperatively and at 1, 6, 12, and 24 months postoperatively. Functional outcomes were measured with the NRS for pain, Knee Society Score (KSS), Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC), and International Knee Documentation Committee (IKDC) scores. Radiographs and MRI were performed preoperatively and at 6- and 12-month follow-ups to verify edema healing and changes in bone structure.

Results

A total of 50 patients were included in the study. The mean follow-up was 26 months (24-30 months). Compared with preoperative values, the mean NRS score decreased at every follow-up point (P < .0001 for all) and the IKDC, WOMAC, and KSS scores improved significantly at 6- and 12-month follow-ups. At 6 months postoperatively, 27 patients (54%) registered a reduction on the NRS of ≥4 points. Postoperative MRI revealed a hypointense zone surrounded by a hyperintense signal at the injection site. Standard radiography showed osteoarthritis grade worsening in 4 (8%) patients. Knee replacement was performed in 11 patients -in 7 patients due to the worsening or persistence of disabling symptoms and in 4 patients due to the progression of osteoarthritis. The leakage of BSM occurred in 6 patients without any clinical consequences during the study period.

Conclusion

About half of the study patients achieved a reduction in the NRS of 4 points at the 6-month follow-up after SCP.

Technological Aspects and Evaluation Methods for Polymer Matrices as Dental Drug Carriers

The development of polymer matrices as dental drug carriers takes into account the following technological aspects of the developed formulations: the composition and the technology used to manufacture them, which affect the properties of the carriers, as well as the testing methods for assessing their behavior at application sites. The first part of this paper characterizes the methods for fabricating dental drug carriers, i.e., the solvent-casting method (SCM), lyophilization method (LM), electrospinning (ES) and 3D printing (3DP), describing the selection of technological parameters and pointing out both the advantages of using the mentioned methods and their limitations. The second part of this paper describes testing methods to study the formulation properties, including their physical and chemical, pharmaceutical, biological and in vivo evaluation. Comprehensive in vitro evaluation of carrier properties permits optimization of formulation parameters to achieve prolonged retention time in the dynamic oral environment and is essential for explaining carrier behavior during clinical evaluation, consequently enabling the selection of the optimal formulation for oral application.

Effectiveness of personalized treatment stage-adjusted digital therapeutics in colorectal cancer: a randomized controlled trial

BACKGROUND

Colorectal cancer survivors often experience decline in physical performance and poor quality of life after surgery and during adjuvant therapies. In these patients, preserving skeletal muscle mass and high-quality nourishment are essential to reduce postoperative complications and improve quality of life and cancer-specific survival. Digital therapeutics have emerged as an encouraging tool for cancer survivors. However, to the best of our knowledge, randomized clinical trials applying personalized mobile application and smart bands as a supportive tool to several colorectal patients remain to be conducted, intervening immediately after the surgical treatment.

METHODS

This study is a prospective, multi-center, single-blinded, two-armed, randomized controlled trial. The study aims to recruit 324 patients from three hospitals. Patients will be randomly allocated to two groups for one year of rehabilitation, starting immediately after the operation: a digital healthcare system rehabilitation (intervention) group and a conventional education-based rehabilitation (control) group. The primary objective of this protocol is to clarify the effect of digital healthcare system rehabilitation on skeletal muscle mass increment in patients with colorectal cancer. The secondary outcomes would be the improvement in quality of life measured by EORTC QLQ C30 and CR29, enhanced physical fitness level measured by grip strength test, 30-sec chair stand test and 2-min walk test, increased physical activity measured by IPAQ-SF, alleviated pain intensity, decreased severity of the LARS, weight, and fat mass. These measurements will be held on enrollment and at 1, 3, 6 and 12 months thereafter.

DISCUSSION

This study will compare the effect of personalized treatment stage-adjusted digital health interventions on immediate postoperative rehabilitation with that of conventional education-based rehabilitation in patients with colorectal cancer. This will be the first randomized clinical trial performing immediate postoperative rehabilitation in a large number of patients with colorectal cancer with a tailored digital health intervention, modified according to the treatment phase and patient condition. The study will add foundations for the application of comprehensive digital healthcare programs focusing on individuality in postoperative rehabilitation of patients with cancer.

Factors associated with clinically relevant pain reduction after a self-management program including education and exercise for people with knee and/or hip osteoarthritis: Data from the BOA register

AIM

To examine the associations between individual- and disease-related factors and the odds of reaching a clinically relevant pain reduction in people with knee and/or hip osteoarthritis (OA) who underwent a first-line self-management program.

MATERIALS AND METHODS

An observational registry-based study including people with knee (n = 18,871) and hip (n = 7,767) OA who participated in a self-management program including education and exercise and had data recorded in the Better Management of patients with Osteoarthritis (BOA) register. We used multivariable logistic regression models to study the association between sex, age, body mass index (BMI), education, comorbidity, pain frequency, walking difficulties, willingness to undergo surgery and the odds of reaching a clinically relevant pain reduction (decrease of >33% on a 0-10 NRS scale) 3 and 12 months after the intervention. All analyses were stratified by joint (knee/hip).

RESULTS

Both in the short- and long-term follow-up, a younger age (18-65 years), a lower BMI (< 25), a higher level of education (university), the absence of comorbidities impacting the ability to walk, less frequent pain and not being willing to undergo surgery were associated with higher odds of reaching a clinically relevant pain reduction in people with knee OA. We found similar results for people with hip OA, but with larger uncertainty in the estimates (wider 95% CI).

CONCLUSION

Our study suggests that early fist line self-management interventions delivered when people have unilateral hip or knee OA with less frequent pain and are unwilling to undergo surgery, may be important for reaching a clinically relevant pain reduction after participation. Providing the most appropriate treatment to the right patient at the right time is a step in reducing the burden of OA for society and the patient.

Pain phenotyping and investigation of outcomes in physical therapy: An exploratory study in patients with low back pain

Phenotypes have been proposed as a method of characterizing subgroups based on biopsychosocial factors to identify responders to analgesic treatments. This study aimed to, first, confirm phenotypes in patients with low back pain receiving physical therapy based on an a priori set of factors used to derive subgroups in other pain populations. Second, an exploratory analysis examined if phenotypes differentiated pain and disability outcomes at four weeks of physical therapy. Fifty-five participants completed psychological questionnaires and pressure pain threshold (PPT). Somatization, anxiety, and depression domains of the Symptom-Checklist-90-Revised, and PPT, were entered into a hierarchical agglomerative cluster analysis with Ward's method to identify phenotypes. Repeated measures ANOVAs assessed pain ratings and disability by phenotype at four weeks. Three clusters emerged: 1) high emotional distress and pain sensitivity (n = 10), 2) low emotional distress (n = 34), 3) low pain sensitivity (n = 11). As an exploratory study, clusters did not differentiate pain ratings or disability after four weeks of physical therapy (p's>0.05). However, trends were observed as magnitude of change for pain varied by phenotype. This supports the characterization of homogenous subgroups based on a protocol conducted in the clinical setting with varying effect sizes noted by phenotype for short-term changes in pain. As an exploratory study, future studies should aim to repeat this trial in a larger sample of patients.

Translation, cross-cultural adaptation and validation of the Italian version of the knee outcome survey - activities of daily living scale

PURPOSE

The Knee Outcome Survey - Activities of Daily Living Scale (KOS-ADLS) is a joint-specific questionnaire measuring symptoms and functional limitations experienced by individuals with painful knee disorders. The original version of the KOS-ADLS has been shown to be reliable, valid and responsive to change. The purpose of this study was to perform a translation and cross-cultural adaptation of the KOS-ADLS into Italian and to assess its reliability and validity.

METHODS

In accordance with standard procedures, the original version of the KOS-ADLS was translated and cross-culturally adapted into Italian (KOS-ADLS-I). Then, the KOS-ADLS-I was administered to 150 patients with knee disorders. A subsample of patients compiled the KOS-ADLS-I again after five/seven days later to evaluate test-retest reliability. Symptoms and function-oriented questionnaires were also completed to evaluate construct validity. Structural validity (Explanatory Factor Analysis [EFA]), internal consistency (Cronbach's alpha), test-retest reliability (Intraclass Correlation Coefficient [ICC]), measurement error (Standard Error of the Measurement [SEM], Minimal Detectable Change [MDC]), and construct validity (hypothesis testing) were assessed.

RESULTS

The cross-cultural adaptation procedure revealed no major problems. EFA revealed a unidimensional structure. Internal consistency was high (Cronbach's alpha = 0.976) and the test-retest reliability was excellent (ICC = 0.990, 95%CI: 0.980-0.995) with low measurement error (SEM = 2.6 points; MDC = 7.1 points). The construct validity resulted to be satisfactory, as 100% a-priori hypothesis were met.

CONCLUSIONS

The KOS-ADLS-I is a reliable and valid questionnaire for the assessment of symptoms and functional limitations in individuals with musculoskeletal knee disorders and it can be used in clinical practice and research.

Heart rate variability is not suitable as surrogate marker for pain intensity in patients with chronic pain

ABSTRACT

The search towards more objective outcome measurements and consequently surrogate markers for pain started decades ago; however, no generally accepted biomarker for pain has qualified yet. The goal is to explore the value of heart rate variability (HRV) as surrogate marker for pain intensity chronic pain setting. Pain intensity scores and HRV were collected in 366 patients with chronic pain, through a cross-sectional multicenter study. Pain intensity was measured with both the Visual Analogue Scale and Numeric Rating Scale, while 16 statistical HRV parameters were derived. Canonical correlation analysis was performed to evaluate the correlation between the dependent pain variables and the HRV parameters. Surrogacy was determined for each HRV parameter with point estimates between 0 and 1 whereby values close to 1 indicate a strong association between the surrogate and the true endpoint at the patient level. Weak correlations were revealed between HRV parameters and pain intensity scores. The highest surrogacy point estimate was found for mean heart rate as marker for average pain intensity on the Numeric Rating Scale with point estimates of 0.0961 (95% CI from 0.0384 to 0.1537) and 0.0209 (95% CI from 0 to 0.05) for patients without medication use, and medication use respectively. This study indicated that HRV parameters as separate entities are no suitable surrogacy candidates for pain intensity, in a population of chronic pain patients. Further potential surrogate candidates and clinical robust true endpoints should be explored, in order to find a surrogate measure for the highly individual pain experience.

Effect of monopolar capacitive resistive radiofrequency in treating stress urinary incontinence: A pilot randomized control trial

Objective

To assess the effectiveness of 448 kHz monopolar capacitive resistive radiofrequency (MCRR) in the treatment of females with stress urinary incontinence (SUI).

Materials and methods

Forty females with SUI complaints were separated randomly into two equal groups. Group A with 20 females received the MCRR therapy for 20 min and performed pelvic floor exercises for 20 min. Group B with 20 females received placebo treatment by applying the same application as in Group A without emitting any waves for 20 min, three times a week, for 4 weeks. The patients in both groups were instructed to pause the treatment during their menstruation; the patients were instructed to maintain home pelvic floor exercises. Both groups were assessed by a perineometer that was used to assess the strength of the pelvic floor muscles (PFM), the visual analogue scale (VAS), and the Incontinence Symptom Severity Index to assess the frequency of urinary incontinence symptoms as described by each patient before treatment and after 4 weeks of treatment.

Results

There was a significant reduction (p < 0.05) in VAS and the Incontinence Symptom Severity Index and a significant increase in the strength of the PFM in both groups post-treatment compared with the pre-treatment. Regarding between-subject effects, there was a significant difference in VAS, the Incontinence Symptom Severity Index, and the perineometer between both groups (p < 0.05), and this significant improvement favored Group A.

Conclusion

MCRR and pelvic floor exercises are more effective methods for the treatment of SUI than just pelvic floor exercises of females with SUI.

Effectiveness of a personalized digital exercise and nutrition-based rehab program for patients with gastric cancer after surgery: Study protocol for a randomized controlled trial

Background

Patients with gastric cancer often encounter impaired quality of life and reduced tolerability to adjuvant treatments after surgery. Weight preservation is crucial for the overall prognosis of these patients, and exercise and supplemental nutrition play the main role. This study is the first randomized clinical trial to apply personalized, treatment stage-adjusted digital intervention with wearable devices in gastric cancer rehabilitation intervention for 12 months, commencing immediately after surgery.

Methods

This is a prospective, multicenter, two-armed, randomized controlled trial and aims to recruit 324 patients from two hospitals. Patients will be randomly allocated to two groups for 1 year of rehabilitation, starting immediately after the operation: a personalized digital therapeutic (intervention) group and a conventional education-based rehabilitation (control) group. The primary objective is to clarify the effect of mobile applications and wearable smart bands in reducing weight loss in patients with gastric cancer. The secondary outcomes are quality of life measured by the EORTC-QLQ-C30 and STO22; nutritional status by mini nutrition assessment; physical fitness level measured by grip strength test, 30-s chair stand test and 2-min walk test; physical activity measured by IPAQ-SF; pain intensity; skeletal muscle mass; and fat mass. These measurements will be performed on enrollment and at 1, 3, 6, and 12 months thereafter.

Conclusions

Digital therapeutic programs include exercise and nutritional interventions modified by age, body mass index, surgery type and postoperative days. Thus, expert intervention is pivotal for precise and safe calibration of this program.

Assessment of visceral pain with special reference to chronic pancreatitis

A thorough pain assessment is of utmost importance when managing pain in clinical practice as it is the foundation for defining pain in need of treatment, either interventional or pharmacological. Pain characteristics can also guide interventional strategies and help evaluate the effect of treatment. In research settings, standardized pain assessment is crucial to improve comparability across studies and facilitate meta-analysis. Due to the importance of thorough visceral pain assessment, this manuscript describes the key elements of pain evaluation focusing on chronic pancreatitis. Most studies in pain assessment have focused on somatic pain, and although chronic pain often shares characteristics between etiologies, some differences must be addressed when assessing visceral pain. Especially differences between somatic and visceral pain are apparent, where visceral pain is diffuse and difficult to localize, with referred pain aspects and often autonomic symptoms dominating the clinical picture. These aspects need to be incorporated into the pain assessment instrument. The manuscript will discuss the different ways of assessing pain, including unidimensional measurement scales, multidimensional questionnaires, and quantitative sensory testing. The advantages and challenges linked to the different methods will be evaluated.

The influence of local pain on balance control in patients with chronic ankle instability

Background

Local pain around the ankle joint is a common symptom in patients with chronic ankle instability (CAI). However, whether the local pain would impose any influence on the balance control performance of CAI patients is still unknown.

Methods

A total of twenty-six subjects were recruited and divided into the following two groups: pain-free CAI (group A) and pain-present CAI (group B). Subjects in both groups received two independent tests: the star excursion balance test and the single-leg stance test, in order to reflect their balance control ability more accurately.

Results

Compared with group A, the group B showed significantly more episodes of the history of sprains, decreased ankle maximum plantarflexion angle, and lower Cumberland scores (all p < 0.05). In the star excursion balance test, group B demonstrated a significantly reduced anterior reach distance than group A (p < 0.05). During the single leg stance test, group B showed a significant increase in the magnitude of electromyographic signals both in peroneus longus and soleus muscles than group A (each p < 0.05). Additionally, group B had a significantly more anterolaterally positioned plantar center of pressure than group A (p < 0.05).

Conclusion

CAI patients with local pain around the ankle joint had more episodes of sprains and lower functional scores when compared to those without pain. The balance control performance was also worse in the pain-present CAI patients than those without pain.

Relationship between Facial Color Changes and Psychological Problems Associated with Lower Back Pain

Background and Objectives: The aim of this study was to determine whether a non-contact sensor that detects complexion changes can be used to assess the psychological state of patients with chronic lower back pain (LBP). Materials and Methods: Twenty-six patients with LBP (LBP group; mean age = 68.0 ± 13.9 years) and 18 control subjects without LBP (control group; mean age = 60.8 ± 16.1 years) were included in the study. All the subjects in the two groups wore headphones when asked LBP-related and LBP-unrelated questions. During questioning, the facial image of the subjects was captured using a video camera, and the complexion of the subjects was converted into red, green, and blue (RGB) values. RGB correlation coefficients (RGBCCs; range: 0-1) represent the difference in complexion between LBP-related and LBP-unrelated questions. A high RGBCC indicates that the brain is more activated by LBP-related questions than by LBP-unrelated questions. We also noted the scores of subjects on the Numerical Rating Scale (NRS), Japanese Orthopedic Association Back Pain Evaluation Questionnaire (JOABPEQ), Pain Catastrophizing Scale (PCS), and Hospital Anxiety and Depression Scale (HADS). Results: There were no significant differences in RGBCC between the control and LBP groups (0.64 versus 0.56, p = 0.08). In the LBP group, no correlation was observed between RGBCC and each examination item of NRS, JOABPEQ, and HADS. In contrast, a correlation was observed between RGBCC and the rumination subscale of PCS in the LBP group (Spearman's rank correlation coefficient = 0.40, p = 0.04). Conclusions: The complexion of patients with catastrophic thinking changes when the patients are asked LBP-related questions.

Sequential Ultrasound Assessment of Peri-Articular Soft Tissue in Adhesive Capsulitis of the Shoulder: Correlations with Clinical Impairments—Sequential Ultrasound in Adhesive Capsulitis

Recently, ultrasound measurements of the shoulder such as thickening of the rotator interval (RI) and the axillary recess (AR) are suggested as specific indicators of adhesive capsulitis. Herein, we evaluated the sequential changes in ultrasound parameters and clinical impairments and the correlation between the two in the case of adhesive capsulitis through a prospective observational study of 56 patients with adhesive capsulitis. Clinical assessments and ultrasound parameters, including the thicknesses of the RI and AR, were surveyed at baseline and after 1, 3, and 6 months. In 56 patients with adhesive capsulitis, the thickness of the AR significantly decreased at each follow-up evaluation, but the thickness of the RI showed a significant decrease only between the baseline and 1-month evaluation. In repeated analyses of correlation, the thickness of the AR was strongly correlated with all clinical impairments except the pain at rest and range of internal rotation in the affected shoulder. The thickness of AR was correlated with clinical impairments in patients with adhesive capsulitis during the 6 months follow up and could be useful as a surrogate marker in patients with adhesive capsulitis.

Headache: What to ask, how to examine, and which scales to use. Recommendations of the Spanish Society of Neurology's Headache Study Group

INTRODUCTION

Headache is the most common neurological complaint at the different levels of the healthcare system, and clinical history and physical examination are essential in the diagnosis and treatment of these patients. With the objective of unifying the care given to patients with headache, the Spanish Society of Neurology's Headache Study Group (GECSEN) has decided to establish a series of consensus recommendations to improve and guarantee adequate care in primary care, emergency services, and neurology departments.

METHODS

With the aim of creating a practical document, the recommendations follow the dynamics of a medical consultation: clinical history, physical examination, and scales quantifying headache impact and disability. In addition, we provide recommendations for follow-up and managing patients' expectations of the treatment.

CONCLUSIONS

With this tool, we aim to improve the care given to patients with headache in order to guarantee adequate, homogeneous care across Spain.
