Investigating the relationship between pain and discomfort and quality of life, using the WHOQOL

Health-Related Quality of Life with Six Domains: A Comparison of Healthcare Providers without Chronic Diseases and Participants with Chronic Diseases

Background/Objectives: This study aims to compare the health-related quality of life (HRQOL) between healthcare providers without chronic diseases and participants with chronic diseases presenting with one of the four different primary diagnoses on the health-related quality of life with six domains (HRQ-6D) scale. Methods: This is a cross-sectional study to compare the HRQOL between healthcare providers without chronic diseases and participants with chronic diseases. Data collection was performed from May 2022 to May 2023. Data for the comparison group were taken from healthcare providers without chronic diseases, and for the participant group with chronic diseases, the data were collected from actual patients with one of four types of primary diagnoses who were recruited from specialist cardiology, oncology, psychiatry, and nephrology clinics. All the participants of this study filled in the HRQ-6D. Results: There were 238 (58.6%) healthcare providers without chronic diseases who participated in this study, as well as 41 (10.1%) patients with end-stage renal disease (ESRD), 48 (11.8%) patients with cancer, and 40 (9.9%) patients who were depressed, and the remaining patients had heart disease. The means (SD) of HRQ-6D scores among healthcare providers without chronic diseases for pain, physical strength, emotion, mobility, self-care, perception of future health, and overall HRQ-6D score were 75.3% (19.8), 74.5% (21.1), 85.6% (18.4%), 93.0% (12.3), 91.6% (13.9), 74.2% (23.3), and 82.4% (13.6), respectively. In comparisons between healthcare providers without chronic diseases and participants with chronic diseases, all mean differences of the overall HRQ-6D score and its domains and dimensions were statistically significant (p < 0.001). Conclusions: The overall score of the HRQ-6D, as well as its domains and dimensions are sensitive in detecting the study participants with chronic diseases from among those without chronic diseases. Therefore, the HRQ-6D is a reliable and valid scale to measure HRQOL. Future studies may use this scale for interventional, observational, and cost-effectiveness studies.

Correlation Between Cancer Pain and Quality of Life in Patients With Advanced Cancer Admitted to a Palliative Care Unit

INTRODUCTION

Cancer pain is one of the most prevalent manageable symptoms in patients with advanced cancer, and it has a negative impact on quality of life (QoL).

OBJECTIVE

The aim of this study is to examine the correlation between cancer pain and QoL in patients with advanced cancer who are hospitalized in a palliative care unit.

METHODS

This study is a cross-sectional analysis of patients with advanced cancer who were hospitalized with cancer pain at a specialized palliative care unit between June 2021 and February 2022. Pain intensity and its impact on daily activities were assessed using the Brief Pain Inventory (BPI), while the European Organization for Research and Treatment of Cancer (EORTC) Quality of Life Questionnaire Core 15 PAL (QLQ-C15-PAL) was used to evaluate QoL.

RESULTS

A total of 104 patients with cancer pain were included, with a mean age of 53.6 years (±14.1). Most of the patients were female (65.38%), and the most common primary tumor site was in the gastrointestinal tract (22.11%). The most frequently reported site of cancer pain was the abdomen (32.69%). The mean duration of cancer pain was 52.3 days (±6.2). The domains of QoL most strongly correlated with cancer pain were weakness (coefficient = .52, P < .001), nausea (coefficient = .36, P < .001), and the physical domain (coefficient = -.30, P < .001).

CONCLUSION

Cancer pain is strongly correlated with a deterioration in QoL in patients with advanced cancer, and its management should be pursued as a strategy for optimizing QoL.

Preoperative Counseling in Spinal Cord Stimulation: A Designated Driver in Implantable Pulse Generator-Related Inconveniences?

BACKGROUND

Spinal cord stimulation (SCS) has been reported to cause substantial pain relief and improved quality of life (QoL) in patients with persistent spinal pain syndrome (PSPS). Despite implantable pulse generator (IPG)-related inconveniences such as pain, shame, and discomfort affecting QoL and patient satisfaction, these are often neglected. Hence, the current study aims to determine the associations between patient satisfaction, IPG-related inconveniences, and preoperative counseling in a homogeneous group of patients with PSPS receiving SCS with IPG implantation in the gluteal or abdominal area.

MATERIALS AND METHODS

Retrospective data on sample characteristics were gathered from the EPIC (electronic health record software) digital patient data base. Prospective data on patient satisfaction were obtained with a questionnaire that covered various topics such as shame, pain, disturbances in daily/intense activities, night rest and/or sleep, discomfort caused by clothing, and preoperative counseling. The exact location of the IPG and its scar were determined with photo analysis. Thereafter, the site of IPG placement was classified into separate quadrants within the gluteal and abdominal area. Patient satisfaction was defined as accepting the current location of the IPG without having the wish to undergo revision surgery.

RESULTS

In total, 81 participants (50.9 ± 10 years) were included in this analysis, with patient satisfaction observed in 61 patients (75.3%). Among satisfied patients, more extensive preoperative counseling concerning IPG pain and discomfort was reported compared with patients who were not satisfied (p < 0.001). When comparing the two groups, significant differences were found in shame (8/81, 9.9%), IPG site pain (21/81, 25.9%), disturbance of activities (42/81, 51.9%), and clothing-related discomfort (42/81, 51.9%).

CONCLUSIONS

On the basis of the current results, shared decision-making and comprehensive preoperative provision of information are recommended to optimize patient satisfaction regarding IPG pain, discomfort, and inconveniences. Although many patients experience these disadvantages despite successful SCS for pain related to PSPS, most of them accept this if they have received adequate preoperative information about expectations.

Efficacy of soothing cream gel in the range of motion and chronic pain at the shoulder and elbow: protocol of a double-blinded, randomised, placebo-controlled trial

INTRODUCTION

Upper limb problems have a significant impact on the global population leading to pain and restricted joint mobility, ultimately impacting their quality of life. Traditional treatments, such as non-steroidal anti-inflammatory drugs and corticosteroids, often come with undesirable side effects, prompting patients to seek alternative therapies. In this trial, we hypothesise that soothing cream gel (SCG) will improve range of motion and chronic pain in the shoulder and elbow. The objective of this trial is to evaluate the efficacy of SCG in improving the range of motion and chronic pain in the shoulder and elbow.

METHODS AND ANALYSIS

A double-blinded, randomised, placebo-controlled trial is conducted to compare the effects of SCG and placebo gel. SCG contains Vitis vinifera essence, Melaleuca viridiflora essential oil, etc, and is manufactured according to Good Manufacturing Practice standards. The placebo gel will be processed with similar appearance, texture and scent but will lack active ingredients. 70 participants with upper limb problems will be recruited from four study sites, including clinical centres and a sport department at the Chinese University of Hong Kong (CUHK). Participants will be randomly assigned to either treatment group or placebo group for 2 weeks. Primary outcome will be the range of motion in the upper limb, assessed by a goniometer, to measure active flexion and abduction for the shoulder, and active flexion and extension for the elbow. The primary efficacy analyses will be based on the full analysis set following the intention-to-treat principle.

ETHICS AND DISSEMINATION

The trial has obtained approval from the joint CUHK-New Territories East Cluster (CRE-2023.142), and the patient enrolment commenced in July 2023. Written informed consent will be obtained from all participants prior to participation. Study results will be disseminated through publication in peer-reviewed journals and presentations at conference.

Systemic antibiotics for symptomatic apical periodontitis and acute apical abscess in adults

BACKGROUND

Dental pain can have a detrimental effect on quality of life. Symptomatic apical periodontitis and acute apical abscess are common causes of dental pain and arise from an inflamed or necrotic dental pulp, or infection of the pulpless root canal system. Clinical guidelines recommend that the first-line treatment for these conditions should be removal of the source of inflammation or infection by local operative measures, and that systemic antibiotics are currently only recommended for situations where there is evidence of spreading infection (cellulitis, lymph node involvement, diffuse swelling) or systemic involvement (fever, malaise). Despite this, there is evidence that dentists frequently prescribe antibiotics in the absence of these signs. There is concern that this could contribute to the development of antibiotic-resistant bacteria. This review is the second update of the original version first published in 2014.

OBJECTIVES

To evaluate the effects of systemic antibiotics provided with or without surgical intervention (such as extraction, incision and drainage of a swelling, or endodontic treatment), with or without analgesics, for symptomatic apical periodontitis and acute apical abscess in adults.

SEARCH METHODS

We searched Cochrane Oral Health's Trials Register (26 February 2018 (discontinued)), CENTRAL (2022, Issue 10), MEDLINE Ovid (23 November 2022), Embase Ovid (23 November 2022), CINAHL EBSCO (25 November 2022) and two trials registries, and performed a grey literature search. There were no restrictions on language or date of publication.

SELECTION CRITERIA

Randomised controlled trials of systemic antibiotics in adults with a clinical diagnosis of symptomatic apical periodontitis or acute apical abscess, with or without surgical intervention (considered in this situation to be extraction, incision and drainage, or endodontic treatment) and with or without analgesics.

DATA COLLECTION AND ANALYSIS

Two review authors independently screened the results of the searches against inclusion criteria, extracted data and assessed risk of bias. We used a fixed-effect model in the meta-analysis as there were fewer than four studies. We contacted study authors to request missing information. We used GRADE criteria to assess the certainty of the evidence.

MAIN RESULTS

There was one new completed trial on this topic since the last update in 2018. In total, we included three trials with 134 participants. Systemic antibiotics versus placebo with surgical intervention and analgesics for symptomatic apical periodontitis or acute apical abscess One trial (72 participants) compared the effects of a single preoperative dose of clindamycin versus a matched placebo when provided with a surgical intervention (endodontic chemo-mechanical debridement and filling) and analgesics to adults with symptomatic apical periodontitis. We assessed this study at low risk of bias. There were no differences in participant-reported pain or swelling across trial arms at any time point assessed. The median values for pain (numerical rating scale 0 to 10) were 3.0 in both groups at 24 hours (P = 0.219); 1.0 in the antibiotic group versus 2.0 in the control group at 48 hours (P = 0.242); and 0 in both groups at 72 hours and seven days (P = 0.116 and 0.673, respectively). The risk ratio of swelling when comparing preoperative antibiotic to placebo was 0.50 (95% confidence interval (CI) 0.10 to 2.56; P = 0.41). The certainty of evidence for all outcomes in this comparison was low. Two trials (62 participants) compared the effects of a seven-day course of oral phenoxymethylpenicillin (penicillin VK) versus a matched placebo when provided with a surgical intervention (total or partial endodontic chemo-mechanical debridement) and analgesics to adults with acute apical abscess or symptomatic necrotic tooth. Participants in both trials also received oral analgesics. We assessed one study at high risk of bias and the other at unclear risk of bias. There were no differences in participant-reported pain or swelling at any time point assessed. The mean difference for pain (short ordinal numerical scale 0 to 3, where 0 was no pain) was -0.03 (95% CI -0.53 to 0.47) at 24 hours; 0.32 (95% CI -0.22 to 0.86) at 48 hours; and 0.08 (95% CI -0.38 to 0.54) at 72 hours. The standardised mean difference for swelling was 0.27 (95% CI -0.23 to 0.78) at 24 hours; 0.04 (95% CI -0.47 to 0.55) at 48 hours; and 0.02 (95% CI -0.49 to 0.52) at 72 hours. The certainty of evidence for all the outcomes in this comparison was very low. Adverse effects, as reported in two studies, were diarrhoea (one participant in the placebo group), fatigue and reduced energy postoperatively (one participant in the antibiotic group) and dizziness preoperatively (one participant in the antibiotic group). Systemic antibiotics without surgical intervention for adults with symptomatic apical periodontitis or acute apical abscess We found no studies that compared the effects of systemic antibiotics with a matched placebo delivered without a surgical intervention for symptomatic apical periodontitis or acute apical abscess in adults.

AUTHORS' CONCLUSIONS

The evidence suggests that preoperative clindamycin for adults with symptomatic apical periodontitis results in little to no difference in participant-reported pain or swelling at any of the time points included in this review when provided with chemo-mechanical endodontic debridement and filling under local anaesthesia. The evidence is very uncertain about the effect of postoperative phenoxymethylpenicillin for adults with localised apical abscess or a symptomatic necrotic tooth when provided with chemo-mechanical debridement and oral analgesics. We found no studies which compared the effects of systemic antibiotics with a matched placebo delivered without a surgical intervention for symptomatic apical periodontitis or acute apical abscess in adults.

Spasmodic Dysphonia Patients' Perception of Pain with Botulinum Toxin Injections

OBJECTIVES

To evaluate spasmodic dysphonia patients' perception of pain associated with laryngeal botulinum toxin (BTX) injections and to determine factors associated with higher pain scores relative to other included patients.

METHODS

Prospective cohort study. Adult patients with adductor spasmodic dysphonia that presented to a tertiary laryngology practice for BTX injections were recruited from March to July 2022. Patients completed the visual analog scale (VAS) pre-procedure to quantify predicted pain. Ten minutes post-procedure they completed VAS and the short form McGill Pain Questionnaire (SF-MPQ). Factors that may affect pain were extracted from charts. Descriptive statistics, univariate, and multivariate analyses were conducted (alpha = 0.05).

RESULTS

One hundred and nineteen patients were included (63 ± 14 yo, 26% Male). SF-MPQ reported mild pain (4.12 ± 4.05 out of 45) with a pain intensity of none to mild (0.70 ± 0.89 out of 5). Bilateral injections yielded significantly higher SF-MPQ scores (5.19 ± 4.66) than unilateral injections (3.30 ± 3.30) (p = 0.012). There was a significant VAS reduction from pre 28.9 ± 24.6 mm (out of 10 mm) to post 24.5 ± 22.3 (p < 0.001). On multiple regression analyses, receiving a bilateral injection significantly (p < 0.05) contributed to a model that predicted higher pre-VAS (p = 0.013). Bilateral injections (p < 0.05) and higher VHI-10 (p < 0.05) contributed to a model that predicted higher total SF-MPQ (p = 0.001) and affective SF-MPQ (p = 0.001) scores. Not being a professional voice user (PVU) significantly (p < 0.05) contributed to a model that predicted higher post-VAS (p = 0.008) scores.

CONCLUSIONS

BTX injections were well tolerated with low pain scores. Factors associated with higher relative predicted or experienced pain included bilateral versus unilateral injection, PVU status, and higher VHI-10.

Assessing the content validity of the Manchester-Oxford Foot Questionnaire in surgically treated ankle fracture patients: a qualitative study

BACKGROUND

Roughly 10% of fractures in adults are ankle fractures. These injuries are found in both sexes and present with different fracture characteristics. The treatment varies with the patients' biology and fracture type, and the goals are to restore stability, prevent pain and maintain ankle function. Clinicians generally use outcomes like assessment of radiography, pain level, or function. The use of patient-reported outcome measures is increasing, and the Manchester-Oxford Foot Questionnaire (MOXFQ) has been shown to have good measurement properties when validated in patients with foot and ankle disorders. However, the instrument has not been validated for ankle fracture patients. This study aims to assess the content validity of the items in MOXFQ in surgically treated ankle fracture patients.

METHODS

A qualitative deductive design was used to investigate patients' response process of the MOXFQ. Individual interviews were conducted using cognitive interviewing based on the theoretical framework of the 4-step model by Tourangeau. Adult patients that were surgically treated for an ankle fracture between four weeks and 18 months were purposively sampled, and interviews followed a semi-structured interview guide. The predetermined categories were comprehension, retrieval, judgement, and response.

RESULTS

Seventeen respondents (65% females) were interviewed. Respondents' age ranged from 27 to 76 years. Some of the respondents in the early recovery phase were limited by post-operative restrictions and did not find the items in the walking/standing domain relevant. Respondents that were allowed weight-bearing as tolerated (WBAT) were able to recall relevant information for most items. Respondents with time since surgery more than 12 months had less pain and remembered fewer relevant episodes in the recall period. Items in the social interaction domain contained ambiguous questions and were generally considered less important by respondents. The summary index score lacked important concepts in measuring overall quality of life.

CONCLUSIONS

Pain was a central concept in the post-operative recovery of ankle fracture patients. The MOXFQ-subscales for pain and walking/standing had acceptable content validity in patients that were allowed WBAT. The social interaction-subscale and the summary index score had insufficient content validity for this patient population.

Measuring population health and quality of life: Developing and testing of the significant quality of life measure (SigQOLM)

Quality of life (QOL) should ideally be determined by a broader spectrum of measurable parameters. This study aims to develop and validate a study instrument that is designed to determine a holistic measure of health and non-health aspects of QOL, and it is called the 'Significant Quality of Life Measure' (SigQOLM). This study involves five phases which aim to (i) explore and understand the subject matter content, (ii) develop a questionnaire, (iii) assess its content validity and face validity, (iv) conduct a pilot study, and lastly (v) perform a field-test by using the questionnaire. For the field-testing phase, a cross-sectional study was conducted which elicited responses from healthcare workers via a self-administered survey for all the SigQOLM items. Based on the results, the overall framework of the SigQOLM consists of four elements, 18 domains with 69 items. The element of "Health" is measured by nine domains, while "Relationships", "Functional activities, and "Survival" are measured by three domains respectively. The SigQOLM has been developed successfully and then validated with a high level of reliability, validity, and overall model fit. Therefore, the SigQOLM will provide researchers and policymakers another viable option to elicit a more comprehensive outcome measure of QOL which shall then enable them to implement specific interventions for improving the QOL of all the people, both healthy or otherwise.

Resilience is associated with cortical gray matter of the antinociceptive pathway in people with chronic pain

Resilience is an important personal characteristic that influences health and recovery. Previous studies of chronic pain suggest that highly resilient people may be more effective at modulating their pain. Since brain gray matter in the antinociceptive pathway has also been shown to be abnormal in people with chronic pain, we examined whether resilience is related to gray matter in regions of interest (ROIs) of the antinociceptive pathway (rostral and subgenual anterior cingulate cortex (rACC, sgACC), anterior insula (aINS), dorsolateral prefrontal cortex (dlPFC)) normally and in people who are experiencing chronic pain. We extracted gray matter volume (GMV) and cortical thickness (CT) from 3T MRIs of 88 people with chronic pain (half males/females) and 86 healthy controls (HCs), who completed The Resilience Scale and Brief Pain Inventory. We found that resilience scores were significantly lower in people with chronic pain compared to HCs, whereas ROI GMV and CT were not different between groups. Resilience negatively correlated with average pain scores and positively correlated with GMV in the bilateral rACC, sgACC, and left dlPFC of people with chronic pain. Mediation analyses revealed that GMV in the right rACC and left sgACC partially co-mediated the relationship between resilience and average pain in people with chronic pain. The resilience-pain and some resilience-GMV relationships were sex-dependent. These findings suggest that the antinociceptive pathway may play a role in the impact of resilience on one's ability to modulate chronic pain. A better understanding of the brain-resilience relationship may help advance evidence-based approaches to pain management.

Development of a Quality-of-Life Instrument to Measure Current Health Outcomes: Health-Related Quality of Life with Six Domains (HRQ-6D)

Health-related quality of life (HRQOL) is one of the most important outcome measures to be assessed by medical research. This study aims to develop and validate an instrument called the "health-related quality of life with six domains" (HRQ-6D), which aims to measure an individual's health-related quality of life within a 24 h period of time. This is a questionnaire development study involving five phases, which are (i) to explore the subject matter content for gaining a better understanding of the topic, (ii) to develop the questionnaire, (iii) to assess both its content validity and face validity, (iv) to conduct a pilot study, and finally, (v) to undertake a field testing of the questionnaire. For the field-testing phase, a cross-sectional study involving a self-administered survey for HRQ-6D items was conducted among healthcare workers with various health conditions. Exploratory factor analysis was initially applied to construct the major dimensions of the HRQ-6D. Confirmatory factor analysis was subsequently applied to evaluate the model fit of the overall framework of the HRQ-6D. The clinical utility of this HRQ-6D was also assessed via its association with actual clinical evidence. A total of 406 respondents participated in the survey. Six domains were identified from the analysis, namely "pain", "physical strength", "emotion", "self-care", "mobility", and "perception of future health" comprising two items in each domain. Each domain was reported to have a minimum value of Cronbach's alpha of 0.731, and the model fit for the overall framework of the HRQ-6D was also found to be excellent. Exploratory factor analysis was undertaken for the 12 items of the HRQ-6D. All the domains can be categorized into three major dimensions, namely "health", "body function", and "future perception", with a minimum value for their factor loadings of at least 0.507. A notable finding was that the HRQ-6D was significantly associated with an individual's existing comorbidities and current status of health (p < 0.05). This study successfully validated the HRQ-6D, and we found it to possess both excellent levels of reliability and validity and a satisfactory degree of model fit; it was also significantly associated with actual clinical evidence.

Equity Reporting in Systematic Reviews of Opioid Treatment of Chronic Non-Cancer Pain with Patient-Reported Outcomes

Chronic non-cancer pain can affect a patient's social life, ability to work, and overall quality of life (QoL). Opioid therapy is often prescribed as therapeutic treatment in chronic pain. Systematic reviews (SRs)-the pinnacle of research quality-are often used in guideline development; however, pain may differ across cultures and communities. Thus, examination of equity reporting in such SR is necessary. This study examines reporting using the PROGRESS (Place of resident, Race, Occupation, Gender, Religion, Education, Socioeconomic status, Social capital)-Plus framework to examine equity within SRs with patient reported outcomes of chronic, non-cancer pain. A systematic search for SRs was conducted, which were evaluated for PROGRESS-Plus items and study characteristics were extracted. Among the 46 included SRs, seven did not include any PROGRESS-Plus items. The most commonly reported items were age, included within 34 SRs, followed by gender (30/46), and duration of pain (14/46). All other items were reported in five or less studies. Our investigation revealed a deficiency in SR's reporting of equity measures for opioid treatment of chronic non-cancer pain. Given the need to address healthcare disparities among minorities, implementing the PROGRESS-Plus framework may influence QoL and patient-centered care.

Investigating the Relationship between Empowerment and Chronic Pain Acceptance and the Resulting Limitations in the Elderly with Diabetes living Southwest of Iran

BACKGROUND AIM

Considering the importance of pain acceptance in adjusting to chronic pain among diabetic patients, this study was conducted to determine the relationship between the empowerment scale and the level of chronic pain acceptance among the elderly with diabetes and the resulting limitations.

METHOD

This is a descriptive-analytical study on 250 older patients (65 years and older) with diabetes. The samples were selected through random convenience sampling, performed during 2019 to 2020 in the health centers of Ahvaz, Iran. The data were collected using the demographic information checklist and standard questionnaires including chronic pain acceptance questionnaire (CPAQ), the scale of chronic pain-related limitations, and the diabetes empowerment scale-short form (DES-SF). The data were analyzed using SPSS V24.

RESULTS

The majority of the samples were male (56%) and the mean age of the participants was 70.96 ± 8.95 years. The results showed that the mean and standard deviation were reported to be 20.04 ± 4.63 for pain acceptance, 46.16 ± 10.85 for chronic pain-related limitations, and 27.24 ± 9.65 for the empowerment scale. According to regression coefficients, the mean score of empowerments of patients with diabetes has no significant relationship with pain acceptance (p = .199, b = -0.327) and pain-related limitations (p = .925, b = 0.004).

CONCLUSIONS

Based on the results of this study, the level of empowerment, pain acceptance, and pain-related limitations in the older patients with diabetes was moderate and there was no significant relationship between them. Identifying vulnerable groups in the field of chronic pain and preventive, educational and therapeutic interventions will help increase patients' self-care capacity and reduce the limitations and the disability caused by pain.

Assessment and management of pain/nociception in patients with disorders of consciousness or locked-in syndrome: A narrative review

The assessment and management of pain and nociception is very challenging in patients unable to communicate functionally such as patients with disorders of consciousness (DoC) or in locked-in syndrome (LIS). In a clinical setting, the detection of signs of pain and nociception by the medical staff is therefore essential for the wellbeing and management of these patients. However, there is still a lot unknown and a lack of clear guidelines regarding the assessment, management and treatment of pain and nociception in these populations. The purpose of this narrative review is to examine the current knowledge regarding this issue by covering different topics such as: the neurophysiology of pain and nociception (in healthy subjects and patients), the source and impact of nociception and pain in DoC and LIS and, finally, the assessment and treatment of pain and nociception in these populations. In this review we will also give possible research directions that could help to improve the management of this specific population of severely brain damaged patients.

Assessing shoulder disability in orthopaedic specialist care: Introducing the Copenhagen Shoulder Abduction Rating (C-SAR)

BACKGROUND

Differences in shoulder-disability among common shoulder-disorders in orthopaedic specialist care is unknown. Furthermore, rating of shoulder-disability using patient-reported outcomes is time-consuming, and a faster approach is needed.

OBJECTIVES

First, compare shoulder-disability among common shoulder-disorders. Secondly, rate shoulder-disability according to the new and quick Copenhagen Shoulder Abduction Rating (C-SAR) and investigate criterion validity of C-SAR.

METHODS

Cross-sectional study including 325 consecutive patients with shoulder-disorders in orthopaedic specialist care. We assessed shoulder abduction range-of-motion and pain during testing (NRS:0-10), and shoulder-disability using Shoulder Pain and Disability Index (SPADI) subscales. Patients were sub-grouped using C-SAR, which is based on shoulder abduction range-of-motion and pain during testing: Severe (range-of-motion ≤90°), Medium (range-of-motion >90°, NRS:>5), Mild (range-of-motion >90°, NRS:≤5). Shoulder-disability was compared among diagnostic categories and C-SAR subgroups using ANCOVA-models.

RESULTS

Most patients were diagnosed with either subacromial impingement (n = 211) or full-thickness/complete rotator-cuff tear (n = 18), but adhesive capsulitis (n = 22) was the diagnostic category related to worst SPADI scores. Data for C-SAR subgrouping were available from 187/229 (82%) patients with rotator-cuff related disorders (subacromial impingement or rotator-cuff tears). C-SAR subgrouping was not feasible for patient with adhesive capsulitis or glenohumeral injury. Differences in shoulder-disability between Mild (n = 67) and Medium (n = 56) C-SAR subgroups were large for both SPADI-subscales (ES: 1.0, p < .0001). Only SPADI-function differed significantly between Severe (n = 64) and Medium C-SAR subgroups (ES: 0.4, p = .017).

CONCLUSION

In orthopaedic specialist care, adhesive capsulitis relates to highest level of shoulder-disability, while C-SAR is a promising test to rate shoulder-disability for most patients, namely those with rotator-cuff related disorders.

Chiropractic Care and Quality of Life Among Office Workers With Nonspecific Pain: A Cross-Sectional Study

Objective

The aim of this study was to evaluate the quality of life by a self-administered World Health Organization Quality of Life short version survey (WHOQoL-BREF) among office workers with nonspecific pain receiving chiropractic care in Istanbul, Turkey.

Methods

This cross-sectional study included 77 office workers (age interval, 18-65) with nonspecific neck, thoracic, back and/or extremity pain who underwent chiropractic care. Two weeks later, the quality of life was evaluated by a self-administered WHOQoL-BREF. The Numeric Pain Scale to evaluate the perceived pain was administered to all of the participants in the beginning and at the end of the study. Group-level changes on WHOQoL-BREF total score and subdimensions were compared according to descriptive data of office workers. The significance level was set at P ≤ .05.

Results

WHOQoL-BREF scale scores after chiropractic care (mean ± standard deviation) were 71.21% ± 7.91% (total score), 81.49% ± 14.43% (general health), 80.38% ± 10.49% (physical health), 73.16% ± 11.68% (psychological), 70.41% ± 12.43% (social), and 65.58% ± 10.91% (environment). Numeric Pain Scale scores decreased in a statistically significant way when compared with baseline (P ≤ .05). The descriptive statistical analysis of WHOQoL-BREF dimensions revealed that women had significantly higher scores than men, the 18-to-35 age group had higher scores compared with the 50-to-65 age group, and those married had significantly higher scores than those who were not married (P ≤ .05).

Conclusion

The findings of our study suggest that chiropractic care had positive effects on the quality of life of office workers.

A Comparative study of osteoarthritic knee patients between urban and rural areas in knee severity and quality of life

Osteoarthritis Knee (OA) is the leading cause of pain and disability. This may affect the patient’s quality of life (QoL) and lead to the onset of mental disorders. The aim of this study was 1) To find the correlation between the severity of OA, depression, and QoL. 2) To compare the severity of OA knee and QoL between urban and rural areas. 199 patients were diagnosed with OA. All patients had self-assessment with questionnaires in terms of 1) demographic data, 2) the knee severity by using Oxford Knee Score, 3) Depression screening by using Patient Health Questionnaire, and 4) World Health Organization Quality of Life Brief-Thai. The results revealed that OA knee patients had excellent (no abnormal symptoms) and good (mild symptoms) levels of severity were 34.2% and 32.2%, respectively. They also had a good level of QoL. The correlation between residential area and other variables were age group (p < 0.01), severity of osteoarthritis (p < 0.01), and depression (p < 0.05). The severity of OA knee and QoL in the mental health aspect was a significant difference in patients in each age group. (p < 0.01 and p < 0.05, respectively). Depression and QoL were not correlated. The conclusion was patients had less severity of osteoarthritis, good QoL, and no anxiety or depression. Residential areas had no impact on QoL but healthcare providers should explain the treatment plan. The next study should focus on the long term of the patient’s QoL.

French Survey on Pain Perception and Management in Patients with Locked-In Syndrome

Patients with locked-in syndrome (LIS) may suffer from pain, which can significantly affect their daily life and well-being. In this study, we aim to investigate the presence and the management of pain in LIS patients. Fifty-one participants completed a survey collecting socio-demographic information and detailed reports regarding pain perception and management (type and frequency of pain, daily impact of pain, treatments). Almost half of the LIS patients reported experiencing pain (49%) that affected their quality of life, sleep and cognition. The majority of these patients reported that they did not communicate their pain to clinical staff. Out of the 25 patients reporting pain, 18 (72%) received treatment (60% pharmacological, 12% non-pharmacological) and described the treatment efficacy as 'moderate'. In addition, 14 (56%) patients were willing to try other non-pharmacological treatments, such as hypnosis or meditation. This study provides a comprehensive characterization of pain perception in LIS patients and highlights the lack of guidelines for pain detection and its management. This is especially pertinent given that pain affects diagnoses, by either inducing fatigue or by using pharmacological treatments that modulate the levels of wakefulness and concentration of such patients.

What Does the Future Hold? Health-Related Quality of Life 3-12 Years Following a Youth Sport-Related Knee Injury

Knee trauma can lead to poor health-related quality of life (HRQoL) and osteoarthritis. We aimed to assess HRQoL 3–12 years following youth sport-related knee injury considering HRQoL and osteoarthritis determinants. Generic (EQ-5D-5L index, EQ-VAS) and condition-specific (Knee injury and Osteoarthritis Outcome Score quality of life subscale, KOOS QOL) HRQoL were assessed in 124 individuals 3–12 years following youth sport-related knee injury and 129 uninjured controls of similar age, sex, and sport. Linear regression examined differences in HRQoL outcomes by injury group. Multivariable linear regression explored the influence of sex, time-since-injury, injury type, body mass index, knee muscle strength, Intermittent and Constant Osteoarthritis Pain (ICOAP) score, and Godin Leisure-Time Exercise Questionnaire (GLTEQ) moderate-to-strenuous physical activity. Participant median (range) age was 23 years (14–29) and 55% were female. Injury history was associated with poorer KOOS QOL (−8.41; 95%CI −10.76, −6.06) but not EQ-5D-5L (−0.0074; −0.0238, 0.0089) or EQ-VAS (−3.82; −8.77, 1.14). Injury history (−5.14; −6.90, −3.38), worse ICOAP score (−0.40; −0.45, −0.36), and anterior cruciate ligament tear (−1.41; −2.77, −0.06) contributed to poorer KOOS QOL. Worse ICOAP score contributed to poorer EQ-5D-5L (−0.0024; −0.0034, −0.0015) and higher GLTEQ moderate-to-strenuous physical activity to better EQ-VAS (0.10; 0.03, 0.17). Knee trauma is associated with poorer condition-specific but not generic HRQoL 3–12 years post-injury.

Effects of a single dose of tablets containing lactononadecapeptide on cognitive function in healthy adults: a randomized, double-blind, cross-over, placebo-controlled trial

Lactononadecapeptide (LNDP; NIPPLTQTPVVVPPFLQPE) is a memory-improving peptide. The current study aimed to determine the effects of a single dose of tablets containing LNDP on cognitive function in healthy Japanese men aged 30-59 years. A randomized, double-blind, cross-over, placebo-controlled trial was conducted in participants randomly assigned to receive LNDP or placebo tablets. The Uchida-Kraepelin test was used to induce cognitive load in participants as a model of work load. Cognitive function was evaluated using the Japanese version of the CNS Vital Signs. Composite memory and verbal memory were significantly higher following consumption of LNDP than placebo tablets. Carryover effects were observed in attention and concentration domains so that period 1 data was analyzed. LNDP consumption led to higher processing speed, executive function, and cognitive flexibility than placebo. Thus, supplementation with a single dose of LNDP tablets may improve cognitive functions including memory, attention, concentration, and information processing in daily life.

The impact of the number of lifetime stone events on quality of life: results from the North American Stone Quality of Life Consortium

To evaluate the impact of chronic stone recurrence on an individual's quality of life using the validated Wisconsin Stone Quality of Life (WISQOL) questionnaire. We collected cross-sectional data on patients with kidney stones from 14 institutions in North America. A stone event was defined as renal colic, stone-related procedure or emergency department visit. The regression analyses using general linear models and pairwise comparison determined the impact of the number of stone events on quality of life. The median number of stone events among the 2205 patients who completed the questionnaire was 3 (IQR 1-6). The mean total score was 107.4 ± 28.7 (max 140 points). The number of lifetime stone events was an independent predictor of lower quality of life (p < 0.001), specifically, score declined significantly beyond five events. Compared with patients who experienced a single stone event, there was a 0.4, 2.5, and 6.9 point decline in the adjusted mean WISQOL score after 2-5, 6-10, or > 10 events, respectively. The cumulative number of lifetime stone events was associated with a lower quality of life when more than five stone events were occurred. These findings underscore the importance of efforts to determine the underlying metabolic etiology of urolithiasis in the recurrent stone former, and the institution of a regimen to place their stone disease in remission.

Can adequate analgesia be achieved in patients with cirrhosis without precipitating hepatic encephalopathy? A prospective study

Aim of the study

Analgesic use in patients with liver cirrhosis can be associated with increased morbidity and mortality and presents clinicians with a significant and challenging management issue. We evaluated the efficacy of opiate analgesia in patients with cirrhosis, while closely monitoring the side effect profile.

Material and methods

This prospective cohort pilot study compared inpatients with cirrhosis who required regular opiate analgesia to non-cirrhotic patients requiring opiates and patients with cirrhosis who did not require opiates. Participants completed daily surveys to assess for analgesic efficacy and encephalopathy.

Results

Fifty-two patients were initially recruited, of whom 50 patients were analysed in three groups (40 male, 10 female, median age 52 years). These included 13 cirrhotic patients (69% Child-Pugh B or C) requiring regular opiate analgesia, 18 cirrhotic patients (67% Child-Pugh B or C) not receiving regular opiate analgesia, and 19 non-cirrhotic controls. Two patients were excluded due to past stroke and acquired brain injury. All cirrhotic patients received regular lactulose. There was no statistical difference in the adequacy of analgesia between the three groups. The modified orientation log score for encephalopathy remained in the normal range in all but two cirrhotic patients receiving regular opiate analgesia.

Conclusions

Effective pain control is achievable with opiate analgesia in most patients with advanced liver disease without precipitating hepatic encephalopathy.

Work Ability and Quality of Life in Patients with Work-Related Musculoskeletal Disorders

This study aimed to investigate level of work ability and quality of life (QOL) as well as the relationship between them among patients suffering from work-related musculoskeletal disorders (WMSDs) in Taiwan. A cross-sectional study design with continuous sampling and a questionnaire were used to obtain the research data. Controlling for personal characteristics, pain, psychological distress, and social support, multiple linear regressions were adopted to explore the relationship between work ability and overall QOL. Further analyses were also made to clarify the relationships between work ability and each domain of QOL. In total, 165 patients with WMSDs were recruited. Compared with general workers, the participants reported a lower level of work ability and overall QOL. Work ability was significantly associated with overall QOL when covariates were controlled. Among the four domains of QOL, work ability was significantly associated with both the physical and psychological domains. The conclusion was that work ability is a definite factor of QOL for patients with WMSDs; the essence of work ability may be beyond economic function or social support. Strategies to help workers with WMSDs enhance their work ability to fit their new or temporary jobs would be beneficial to their QOL.

Physical Activity and Health-Related Quality of Life in People With Back Pain: A Population-Based Pooled Study of 27,273 Adults

BACKGROUND

To investigate the association between moderate- to vigorous-intensity physical activity (MVPA) and health-related quality of life (HRQoL) in people with back pain.

METHODS

The sample comprised adults aged 16 years and older who participated in the Welsh Health Survey (2011-2015). The HRQoL was evaluated using the 36-item short form. Participants were categorized into 4 groups based on minutes per week of MVPA: inactive (no MVPA), insufficiently active (<150 min/wk), sufficiently active (≥150 and <300 min/wk), and very active (≥300 min/wk). The authors investigated the association between MVPA and HRQoL using generalized linear models and multiple linear regression.

RESULTS

Of the 74,578 adults in the survey cohorts, 27,273 participants diagnosed with back pain were included in the analyses. Consistent direct curvilinear associations between MVPA and HRQoL were demonstrated for all 36-item short form domains (P < .001), in both the minimally and fully adjusted models, with the highest scores observed for sufficiently active and very active participants. Compared with the inactive group, those who were insufficiently active; sufficiently active; and very active had an average difference of 6.31 (95% confidence interval, 5.70-6.92), 7.72 (95% confidence interval, 7.04-8.41), and 8.00 (95% confidence interval, 7.12-8.89) points in the overall HRQoL, respectively.

CONCLUSION

The authors found a consistent direct curvilinear association between MVPA and HRQoL.

Experienced pain after stroke: a cross-sectional 5-year follow-up study

Background

Stroke is one of the most common cause of disability worldwide. Pain is common in both stroke survivors and in the general population. Consequences of post-stroke pain (PSP) include reduced quality of life and are important to consider. The aim of the current study was to explore the experience of pain 5 years after stroke, and factors associated with the experience of pain.

Methods

Inclusion criteria were: First ever stroke, treated at Sahlgrenska University Hospital, Sweden, during an 18 months period in 2009–2010, aged 18 years or older. Furthermore, the participants had to respond to a set of questionnaires 5 years post-stroke. Baseline data were collected from medical records and follow-up data from the set of questionnaires. The primary outcome was based on the question Do you experience pain? Predictors and explanatory factors for experiencing more frequent pain were analysed with logistic regression.

Results

A total of 281 participants were included. Almost 40% experienced pain to some degree 5 years post-stroke (15% reported pain frequently), and 25% felt that their needs for pain treatment were not met. The participants experiencing more frequent pain reported poorer quality of life, self-perceived health status and recovery post-stroke. Functional dependency at discharge from hospital, experiencing depression at follow up and restricted mobility at follow up were all associated with more frequent pain.

Conclusion

Pain is common 5 years post-stroke and the treatment is not perceived as optimal. The persons experiencing more frequent pain seem to rate their health and recovery worse than the persons experiencing less frequent pain. Most of the factors associated with more frequent pain were treatable and this emphasize the importance of standardised follow-up care that takes pain into consideration.

Towards the assessment of quality of life in patients with disorders of consciousness

PURPOSE

To generate foundational knowledge in the creation of a quality-of-life instrument for patients who are clinically diagnosed as being in a vegetative or minimally conscious state but are able to communicate by modulating their brain activity (i.e., behaviourally nonresponsive and covertly aware). The study aimed to identify a short list of key domains that could be used to formulate questions for an instrument that determines their self-reported quality of life.

METHODS

A novel two-pronged strategy was employed: (i) a scoping review of quality-of-life instruments created for patient populations sharing some characteristics with patients who are behaviourally nonresponsive and covertly aware was done to compile a set of potentially relevant domains of quality of life; and (ii) a three-round Delphi consensus process with a multidisciplinary panel of experts was done to determine which of the identified domains of quality of life are most important to those who are behaviourally nonresponsive and covertly aware. Five expert groups were recruited for this study including healthcare workers, neuroscientists, bioethicists, quality-of-life methodologists, and patient advocates.

RESULTS

Thirty-five individuals participated in the study with an average response rate of 95% per round. Over the three rounds, experts reached consensus on 34 of 44 domains (42 domains were identified in the scoping review and two new domains were added based on suggestions by experts). 22 domains were rated as being important for inclusion in a quality-of-life instrument and 12 domains were deemed to be of less importance. Participants agreed that domains related to physical pain, communication, and personal relationships were of primary importance. Based on subgroup analyses, there was a high degree of consistency among expert groups.

CONCLUSIONS

Quality of life should be a central patient-reported outcome in all patient populations regardless of patients' ability to communicate. It remains to be determined how covertly aware patients perceive their circumstances and quality of life after suffering a life-altering injury. Nonetheless, it is important that any further dialogue on what constitutes a life worth living should not occur without direct patient input.

Working in a cold environment, feeling cold at work and chronic pain: a cross-sectional analysis of the Tromsø Study

AIM

The aim of this study was to investigate if working in a cold environment and feeling cold at work are associated with chronic pain (ie, lasting ≥3 months).

METHODS

We used data from the sixth survey (2007-2008) of the Tromsø Study. Analyses included 6533 men and women aged 30-67 years who were not retired, not receiving full-time disability benefits and had no missing values. Associations between working in a cold environment, feeling cold at work and self-reported chronic pain were examined with logistic regression adjusted for age, sex, education, body mass index, insomnia, physical activity at work, leisure time physical activity and smoking.

RESULTS

779 participants reported working in a cold environment ≥25% of the time. This exposure was positively associated with pain at ≥3 sites (OR 1.57; 95% CI 1.23 to 2.01) and with neck, shoulder and leg pain, but not with pain at 1-2 sites. Feeling cold sometimes or often at work was associated with pain at ≥3 sites (OR 1.58; 95% CI 1.22 to 2.07 and OR 3.90; 95% CI 2.04 to 7.45, respectively). Feeling cold often at work was significantly and positively associated with pain at all sites except the hand, foot, stomach and head.

CONCLUSION

Working in a cold environment was significantly associated with chronic pain. The observed association was strongest for pain at musculoskeletal sites and for those who often felt cold at work.

The short-term effect and safety of duloxetine in osteoarthritis: A systematic review and meta-analysis

BACKGROUND

Previous clinical trials indicated that duloxetine may be effective in the treatment of osteoarthritis (OA) pain. This meta-analysis is conducted to evaluate short term analgesic effect and safety of duloxetine in the treatment of OA.

METHODS

Electronic databases were searched in February 2019, including PUBMED, EMBASE, Cochrane Database of Systematic Reviews, Cochrane Central Register of Controlled Trials, Web of Science. All eligible studies should be randomized controlled trials (RCTs) comparing duloxetine treatment group to placebo about OA pain relief and safety outcomes.

RESULTS

Five RCTs with 2059 patients were involved in this systematic review and meta-analysis. Compared to placebo, duloxetine treatment showed significant better result, with higher reduction pain intensity (mean difference [MD] = -0.77, P < .00001), higher rates of both 30% and 50% reduction in pain severity (risk ratio [RR] = 1.42, P < .00001; RR = 1.62, P < .00001), lower mean Patient Global Improvement-Inventory (PGI-I) score (MD = -0.48, P < .00001). The results of the Western Ontario and McMaster Universities (WOMAC) score change from baseline to endpoint also favored duloxetine treatment group in all four categories, including total (MD = -5.43, P < .00001), pain (MD = -1.63, P = .001), physical function (MD = -4.22, P < .00001), and stiffness score (MD = -0.58, P < .00001). There were higher rates of treatment-emergent adverse events (TEAEs) (RR = 1.32, P < .00001) and discontinuation (RR = 1.88, P < .00001) in duloxetine group. However, there was no significant difference in the incidence of severe adverse events (SAEs) between these 2 groups (RR = 0.84, P = .68).

CONCLUSION

Duloxetine was an effective and safe choice to improve pain and functional outcome in OA patients. However, further studies are still needed to find out the optimal dosage for OA and examine its long-term efficacy and safety.

Development and validation of a short version of Chronic Oral Mucosal Disease Questionnaire (COMDQ-15)

BACKGROUND

The adoption of the Chronic Oral Mucosal Disease Questionnaire (COMDQ) into clinical practice has been low, despite its rigorous development process. A potential limitation of the COMDQ is the high response burden to patients. Therefore, the aim of the present study was to develop and validate a short version of the 26-item COMDQ.

METHODS

The COMDQ data of 520 patients with chronic oral mucosal diseases were randomly divided into two subsamples. Descriptive item analysis and exploratory factor analysis (EFA) were performed using data from the first subsample for item reduction and development of the shortened COMDQ. The resulting short version was then validated using confirmatory factor analysis (CFA) on the other subsample. Internal consistency reliability of the short-form COMDQ was assessed using Cronbach's alpha. Criterion validity of this new scale was examined against its original version.

RESULTS

Based upon item analysis, 11 items were dropped. EFA results on the remaining 15 items extracted four factors consistent with the original COMDQ, and CFA results displayed acceptable goodness-of-fit indices of this factor structure on different sample. The COMDQ-15 was then created. Cronbach's alpha of four subscale scores ranged from 0.7 to 0.91, indicating good internal consistency reliability of the COMDQ-15. Correlations between total and subscale scores of the COMDQ-15 and its parent scale were high, supporting good criterion validity of this shortened scale.

CONCLUSION

The COMDQ-15 is a brief, valid and reliable instrument that can give an overview of the patient's quality of life related to their chronic oral mucosal conditions.

What Determines the Quality of Life of Terminally Ill Cancer Patients from Their Own Perspective?

Background

Although several instruments have been developed to measure the quality of life (QOL) of palliative care patients, a rigorous research study has not specifically asked patients themselves what is important to their QOL. It is, therefore, not clear whether these instruments measure what is most important to these patients’ QOL.

Purpose

To understand the primary determinants of the QOL of palliative care patients with cancer.

Method

The study used a qualitative paradigm. Participants were interviewed concerning what was important to their QOL. A systematic content analysis of the transcripts was carried out by all the investigators.

Results

Five broad domains were found to be important determinants of patient QOL: (1) the patient's own state, including physical and cognitive functioning, psychological state, and physical condition; (2) quality of palliative care; (3) physical environment; (4) relationships; and (5) outlook.

Conclusions

Existing instruments cover many of these domains, but no single instrument includes all of the relevant content. The McGill Quality of Life Questionnaire, which we developed previously, has been revised based on these data.

The three-dimensional shoulder pain alignment (3D-SPA) mobilization improves pain-free shoulder range, functional reach and sleep following stroke: a pilot randomized control trial

Background and purpose: Following a stroke, three-dimensional clavicular/scapular/humeral joint rotations may become restricted and contribute to post-stroke shoulder pain. This study examined whether a treatment group provided with current standard treatment plus the proposed "Three-dimensional Shoulder Pain Alignment" mobilization protocol demonstrated improved pain-free shoulder range, functional reach and sleep compared to a control group provided with standard treatment alone.Methods: In this double-blinded parallel-group randomized control trial, treatment and control subjects with moderate/severe post-stroke upper extremity impairment and shoulder pain were treated 3x/week for 4 weeks. Outcome measures included changes in pain-free three-dimensional clavicular/scapular/humeral range (using computerized digitization), pain during sleep and functional reach (using the Pain Intensity-Numerical Rating Scale), and pain location/prognostic indicators (using the Chedoke-McMaster Stroke Assessment-Shoulder Pain Inventory).Results: Compared to controls (n = 10) the treatment group (n = 10) demonstrated significantly improved three-dimensional clavicular/scapular/humeral pain-free range during shoulder flexion and abduction (p < 0.05; Hedges g > 0.80), large effect sizes for decreased pain during sleep and functional reach to the head and back (OR range: 5.44-21.00), and moderate effect size for improved pain/prognostic indicators (OR = 3.86).Conclusions: The Three-Dimensional Shoulder Pain Alignment mobilization protocol significantly improved pain-free range of motion, functional reach and pain during sleep in shoulders with moderate/severe post-stroke upper-extremity impairment.Implications for rehabilitationAlthough three-dimensional clavicular/scapular/humeral rotations are an essential component of normal pain-free shoulder range of motion, current guidelines for treatment of post-stroke shoulder pain only includes uni-dimensional mobilizations for joint alignment and pain management.The Three-Dimensional Shoulder Pain Alignment (3D-SPA) mobilization protocol incorporates multi-dimensional mobilizations in various planes of shoulder movement.The current study results demonstrate proof-of-concept regarding the 3D-SPA mobilization, and this approach should be considered as an alternative to the uni-dimensional mobilizations currently used in clinical treatment guidelines for post-stroke shoulder pain.

Catastrophizing, pain, and functional outcomes for children with chronic pain: a meta-analytic review

Pediatric chronic pain is associated with numerous negative outcomes including increased physical disability, increased rates of depression and anxiety, and decreased quality of life (QOL). Pain catastrophizing-broadly conceptualized as including rumination, magnification, and helplessness cognitions surrounding one's pain-has been linked with poor functional outcomes in children with chronic pain. Pain catastrophizing in pediatric chronic pain is often considered a key factor on which to focus treatment efforts. However, absent a systematic review that integrates the relevant literature, this call for routine assessment and targeted treatment may be premature. This study aimed to: (1) meta-analytically quantify the relationship between catastrophizing and pain and functional/psychosocial outcomes (functional disability/physical functioning, anxiety, depression, and QOL) in children with chronic pain, and (2) examine potential moderators of these relationships. Using a random-effects model, a total of 111 effect sizes from 38 studies were analyzed. Effect sizes ranged from medium to large, with anxiety, depression, and QOL demonstrating a strong association with catastrophizing. Pain intensity and physical disability had a moderate association with catastrophizing. These relationships were robust, minimizing potential publication bias. None of the examined moderators were significant. The strong relationships found between catastrophizing and anxiety, depression, and QOL suggest that successfully intervening on catastrophizing could have far reaching implications in improving pain outcomes in pediatric chronic pain.

Adherence to Consolidated Standards of Reporting Trials (CONSORT) Guidelines for Reporting Safety Outcomes in Trials of Cannabinoids for Chronic Pain: Protocol for a Systematic Review

Background

Chronic pain affects a significant proportion of the population and presents a major challenge to clinicians and pain specialists. Despite the availability of pharmacologic treatment options such as opioids, many patients continue to experience persistent pain. Cannabinoids present an alternative option with some data on efficacy; however, to date, a systematic review of adverse events (AEs) assessment and reporting in randomized clinical trials (RCTs) involving cannabinoids has not been performed. As a result, it is unclear whether a clear profile of cannabinoid-associated AEs has been accurately detailed in the literature. As cannabinoids are likely to become readily available for patients in the near future, it is important to study how well AEs have been reported in trials so that the safety profile of cannabinoids can be better understood.

Objective

With a potentially enormous shift toward cannabinoid use for managing chronic pain and spasticity, this study aims to reveal the adequacy of AE reporting and cannabinoid-specific AEs in this setting. Spasticity is a major contributor to chronic pain in patients with multiple sclerosis (MS), with a comorbidity of 75%. Many cannabinoid studies have been performed in MS-related painful spasticity with relevant pain outcomes, and these studies will be included in this review for comprehensiveness. The primary outcome will be the quality of AE assessment and reporting by adherence to the Consolidated Standards of Reporting Trials (CONSORT) guidelines. Secondary outcomes will include the type of AE, method of AE reporting, severity of AE, frequency of AEs, patient withdrawals, and reasons for withdrawals.

Methods

We will perform a systematic review by searching for primary reports of double-blind, randomized controlled trials of cannabinoids compared with placebo and any active comparator treatments for chronic pain, with a primary outcome directly related to pain (eg, pain intensity, pain relief, and pain-related interference). We will search the following databases: MEDLINE, Embase, Cochrane Library, and PsycINFO. RevMan software will be used for meta-analysis.

Results

The protocol has been registered on the International Prospective Register of Systematic Reviews (CRD42018100401). The project was funded in 2018 and screening has been completed. Data extraction is under way and the first results are expected to be submitted for publication in January or February 2019.

Conclusions

This review will better elucidate the safety of cannabinoids for the treatment of chronic pain and spasticity through identifying gaps in the literature for AE reporting. Like in any new therapy, it is essential that accurate information surrounding the safety and efficacy of cannabinoids be clearly outlined and identified to balance the benefit and harm described for patients.

Impact of 1% malic acid spray on the oral health-related quality of life of patients with xerostomia

Dry mouth sensation, also known as xerostomia, is a common clinical problem with an increasing prevalence. Although recent studies have reported promissory results of malic acid, none have evaluated the impact of malic acid on the oral health-related quality of life (OHRQoL) of patients with xerostomia. Thus, this study aimed to evaluate the impact of 1% malic acid, combined with fluoride and xylitol, on the OHRQoL of patients with xerostomia. We enrolled 70 patients and randomly allocated them into two groups: the intervention group (applied topical sialogogue with 1% malic acid) and the control group (applied a placebo). We assessed the OHRQoL and severity of xerostomia before and after treatment with the Spanish version of the Oral Health Impact Profile-14 questionnaire (OHIP-14sp) and a visual analogue scale (VAS), respectively. In addition, stimulated and non-stimulated salivary flow rates before and after treatments were also measured. In total, 60 patients completed the study. According to the VAS, both sprays significantly improved dry mouth sensation (P < 0.001). However, OHIP-14sp total scores decreased significantly in the intervention group from 20.8 ± 10.4 to 16.5 ± 9.5 (P < 0.001), indicating an improvement in the OHRQoL. No significant differences were observed in the control group (P > 0.05). Furthermore, non-stimulated salivary flow rates significantly increased in the intervention group from 0.25 ± 0.22 to 0.33 ± 0.33 mL/min (P < 0.001). Overall, this study demonstrated that malic acid improves the OHRQoL and dry mouth sensation in patients with xerostomia.

Systemic antibiotics for symptomatic apical periodontitis and acute apical abscess in adults

BACKGROUND

Dental pain can have a detrimental effect on quality of life. Symptomatic apical periodontitis and acute apical abscess are common causes of dental pain and arise from an inflamed or necrotic dental pulp, or infection of the pulpless root canal system. Clinical guidelines recommend that the first-line treatment for teeth with these conditions should be removal of the source of inflammation or infection by local, operative measures, and that systemic antibiotics are currently only recommended for situations where there is evidence of spreading infection (cellulitis, lymph node involvement, diffuse swelling) or systemic involvement (fever, malaise). Despite this, there is evidence that dentists frequently prescribe antibiotics in the absence of these signs. There is concern that this could contribute to the development of antibiotic-resistant bacterial colonies within both the individual and the community. This review is an update of the original version that was published in 2014.

OBJECTIVES

To evaluate the effects of systemic antibiotics provided with or without surgical intervention (such as extraction, incision and drainage of a swelling, or endodontic treatment), with or without analgesics, for symptomatic apical periodontitis and acute apical abscess in adults.

SEARCH METHODS

Cochrane Oral Health's Information Specialist searched the following databases: Cochrane Oral Health's Trials Register (to 26 February 2018), the Cochrane Central Register of Controlled Trials (CENTRAL; 2018, Issue 1) in the Cochrane Library (searched 26 February 2018), MEDLINE Ovid (1946 to 26 February 2018), Embase Ovid (1980 to 26 February 2018), and CINAHL EBSCO (1937 to 26 February 2018). The US National Institutes of Health Ongoing Trials Register (ClinicalTrials.gov) and the World Health Organization International Clinical Trials Registry Platform were searched for ongoing trials. A grey literature search was conducted using OpenGrey (to 26 February 2018) and ZETOC Conference Proceedings (1993 to 26 February 2018). No restrictions were placed on the language or date of publication when searching the electronic databases.

SELECTION CRITERIA

Randomised controlled trials of systemic antibiotics in adults with a clinical diagnosis of symptomatic apical periodontitis or acute apical abscess, with or without surgical intervention (considered in this situation to be extraction, incision and drainage or endodontic treatment) and with or without analgesics.

DATA COLLECTION AND ANALYSIS

Two authors screened the results of the searches against inclusion criteria, extracted data and assessed risk of bias independently and in duplicate. We calculated mean differences (MD) (standardised mean difference (SMD) when different scales were reported) and 95% confidence intervals (CI) for continuous data. A fixed-effect model was used in the meta-analysis as there were fewer than four studies. We contacted study authors to obtain missing information.

MAIN RESULTS

We included two trials in this review, with 62 participants included in the analyses. Both trials were conducted in university dental schools in the USA and compared the effects of oral penicillin V potassium (penicillin VK) versus a matched placebo when provided in conjunction with a surgical intervention (total or partial pulpectomy) and analgesics to adults with acute apical abscess or symptomatic necrotic tooth. The patients included in these trials had no signs of spreading infection or systemic involvement (fever, malaise). We assessed one study as having a high risk of bias and the other study as having unclear risk of bias.The primary outcome variables reported in both studies were participant-reported pain and swelling (one trial also reported participant-reported percussion pain). One study reported the type and number of analgesics taken by participants. One study recorded the incidence of postoperative endodontic flare-ups (people who returned with symptoms that necessitated further treatment). Adverse effects, as reported in one study, were diarrhoea (one participant, placebo group) and fatigue and reduced energy postoperatively (one participant, antibiotic group). Neither study reported quality of life measurements.Objective 1: systemic antibiotics versus placebo with surgical intervention and analgesics for symptomatic apical periodontitis or acute apical abscessTwo studies provided data for the comparison between systemic antibiotics (penicillin VK) and a matched placebo for adults with acute apical abscess or a symptomatic necrotic tooth when provided in conjunction with a surgical intervention. Participants in one study all underwent a total pulpectomy of the affected tooth, while participants in the other study had their tooth treated by either partial or total pulpectomy. Participants in both trials received oral analgesics. There were no statistically significant differences in participant-reported measures of pain or swelling at any of the time points assessed within the review. The MD for pain (short ordinal numerical scale 0 to 3) was -0.03 (95% CI -0.53 to 0.47) at 24 hours; 0.32 (95% CI -0.22 to 0.86) at 48 hours; and 0.08 (95% CI -0.38 to 0.54) at 72 hours. The SMD for swelling was 0.27 (95% CI -0.23 to 0.78) at 24 hours; 0.04 (95% CI -0.47 to 0.55) at 48 hours; and 0.02 (95% CI -0.49 to 0.52) at 72 hours. The body of evidence was assessed as at very low quality.Objective 2: systemic antibiotics without surgical intervention for adults with symptomatic apical periodontitis or acute apical abscessWe found no studies that compared the effects of systemic antibiotics with a matched placebo delivered without a surgical intervention for symptomatic apical periodontitis or acute apical abscess in adults.

AUTHORS' CONCLUSIONS

There is very low-quality evidence that is insufficient to determine the effects of systemic antibiotics on adults with symptomatic apical periodontitis or acute apical abscess.

Effect of Using a Sit-Stand Desk on Ratings of Discomfort, Fatigue, and Sleepiness Across a Simulated Workday in Overweight and Obese Adults

BACKGROUND

Limited research examines the influence of sit-stand desks on ratings of discomfort, sleepiness, and fatigue. This study evaluated the time course of these outcomes over 1 day.

METHODS

Adults (N = 25) completed a randomized cross-over study in a laboratory with two 8-hour workday conditions: (1) prolonged sitting (SIT) and (2) alternating sitting and standing every 30 minutes (SIT-STAND). Sleepiness was assessed hourly. Discomfort, physical fatigue, and mental fatigue were measured every other hour. Linear mixed models evaluated whether these measures differed across conditions and the workday. Effect sizes were calculated using Cohen's d.

RESULTS

Participants were primarily white (84%) males (64%), with mean (SD) body mass index of 31.9 (5.0) kg/m² and age 42 (12) years. SIT-STAND resulted in decreased odds of discomfort (OR = 0.37, P = .01) and lower overall discomfort (β = -0.19, P < .001, d = 0.42) versus SIT. Discomfort during SIT-STAND was lower in the lower and upper back, but higher in the legs (all Ps< .01, d = 0.26-0.42). Sleepiness (β = -0.09, P = .01, d = 0.15) and physical fatigue (β = -0.34, P = .002, d = 0.34) were significantly lower in SIT-STAND. Mental fatigue was similar across conditions.

CONCLUSIONS

Sit-stand desks may reduce acute levels of sleepiness, physical fatigue, and both overall and back discomfort. However, levels of lower extremity discomfort may be increased with acute exposure.

Statistical Alchemy: Conceptual Validity and Mapping to Generate Health State Utility Values

Mapping between non-preference- and preference-based health-related quality-of-life instruments has become a common technique for estimating health state utility values for use in economic evaluations. Despite the increased use of mapped health state utility estimates in health technology assessment and economic evaluation, the methods for deriving them have not been fully justified. Recent guidelines aim to standardise reporting of the methods used to map between instruments but do not address fundamental concerns in the underlying conceptual model. Current mapping methods ignore the important conceptual issues that arise when extrapolating results from potentially unrelated measures. At the crux of the mapping problem is a question of validity; because one instrument can be used to predict the scores on another, does this mean that the same preference for health is being measured in actual and estimated health state utility values? We refer to this as conceptual validity. This paper aims to (1) explain the idea of conceptual validity in mapping and its implications; (2) consider the consequences of poor conceptual validity when mapping for decision making in the context of healthcare resource allocation; and (3) offer some preliminary suggestions for improving conceptual validity in mapping.

Sublingual, transdermal and intravenous patient-controlled analgesia for acute post-operative pain: systematic literature review and mixed treatment comparison

OBJECTIVE

To conduct a systematic literature review (SLR) and quantitative analysis to assess the comparative efficacy and safety of the sufentanil sublingual tablet system (SSTS) against other available patient controlled analgesia (PCA) options for post-operative analgesia.

METHODS

An SLR was conducted for studies published between 2004 and 2016. Due to study heterogeneity, subgroup analyses were conducted controlling for differences in imputation methods for missing values, baseline pain severity, and type of surgery. Where sufficient data was available, a mixed treatment comparison (MTC) was performed.

RESULTS

The MTC and subgroup analyses used 13 studies. In direct meta-analysis, there was a statistically significant difference in favor of SSTS compared with intravenous (IV) PCA (morphine) at 24 hours for the patient global assessment (PGA) scores of "good" or "excellent". For the Pain Intensity Score, there were numerical but not statistically significant differences in favor of the SSTS versus IV PCA (morphine) and the patient controlled transdermal system (PCTS) (fentanyl) in the MTC at 6 hours (standardized mean difference -0.27 [credible interval -2.78, 2.09] and -0.36 [-3.89, 3.03], respectively). The onset of pain relief was earlier with the SSTS versus IV PCA (morphine) as shown by the Pain Intensity Difference. Likewise, the onset was earlier compared with PCTS (fentanyl) where data was available. There was a significant difference in favor of SSTS compared with IV PCA (morphine) and with PCTS (fentanyl) for any adverse event, and numerical improvements for withdrawals due to adverse events.

CONCLUSIONS

This meta-analysis shows that SSTS is an option for non-invasive management of moderate-to-severe post-operative pain which can be more effective, faster in onset and better tolerated than IV PCA (morphine) and PCTS (fentanyl).

Indirect treatment comparison of two non-invasive patient-controlled analgesia treatments for acute post-operative pain management

OBJECTIVES

To evaluate the relative clinical efficacy, safety, and tolerability associated with two non-invasive patient-controlled analgesia (PCA) treatments, sufentanil sublingual tablet system (SSTS) and fentanyl iontophoretic patient-controlled transdermal system (PCTS). These two treatments have recently been approved in the EU for the management of acute moderate-to-severe post-operative pain in adult patients.

METHODS

As no head-to-head trials comparing SSTS and PCTS currently exist, indirect treatment comparison (ITC) analyses were conducted to evaluate SSTS or PCTS versus intravenous (IV) morphine PCA.

RESULTS

Five studies, four assessing PCTS and one assessing SSTS, were included in this analysis. SSTS had statistical or numerical advantages over PCTS for both patient global assessment (PGA) and healthcare professional global assessment (HPGA) outcomes at all time points investigated. SSTS was also associated with greater patient ease of use (weighted mean difference [WMD]: 0.13; 95% confidence interval [CI]: -0.02-0.28) and a higher patient satisfaction score (WMD: 0.31; 95% CI: 0.05-0.57; p = .019) compared with PCTS. In terms of tolerability, all-cause withdrawals from treatment were reported to be less likely with SSTS (risk ratio: 0.65; 95% CI: 0.42-1.02). No significant differences were observed between SSTS and PCTS in terms of safety and adverse events.

CONCLUSIONS

In the absence of direct head-to-head data, the combination of promising phase III trial results compared to IV morphine PCA, a SLR comparison against other opioid treatments, and the results of this exploratory analysis present a strong rationale in support of SSTS as a key option for management of post-operative pain.

Activity Pacing in Chronic Pain Management: One Aim, but Which Method? Part One: Introduction and Literature Review

People with chronic pain often adopt activity patterns that can exacerbate their pain and undermine their quality of life. Activity pacing is considered an essential component of occupational therapy in pain management and other clinical areas to counteract the overactivity-underactivity cycle.

Part one of this paper provides an introduction and literature review on the subject of activity pacing in chronic pain management. Based on case histories, the psychosocial issues arising from underactivity or overactivity, or a combination of the two, are explained. It is demonstrated that activity pacing is ill-defined and subject to discrepancies in practice. In particular, guidance regarding quota-based practice to prevent pain-contingency remains unresolved. Part one concludes that research is needed to clarify both the theory and the practice of activity pacing.

Part two of this paper will present the outcomes of a national occupational therapy survey on activity pacing.

Impact of the number of painful stimuli on life satisfaction among Korean industrial accident workers completing convalescence: dual mediating effects of self-esteem and sleeping time

This study examined the impact of the number of painful stimuli on life satisfaction among workers who experienced an industrial accident and investigated how self-esteem and sleeping time affected life satisfaction. The Korea Workers' Compensation & Welfare Service conducted the first nationwide panel survey on occupational health and safety insurance in 2013-2014 through a stratified systematic sampling on 2,000 industrial accident workers who completed convalescence. Based on the dataset, our study analyzed 1,832 workers experiencing an industrial accident after excluding 168 disease patients. For the research model analysis, a four-stage hierarchical regression analysis technique was applied using the SPSS regression analysis Macro program of PROCESS Procedure. To test mediated indirect effects of the self-esteem and sleeping time, the bootstrapping technique was applied. Life satisfaction, self-esteem and sleeping time decreased as the number of painful stimuli increased. Life satisfaction decreased as self-esteem and sleeping time decreased. On balance, the partial mediation model confirmed that self-esteem and sleeping time both mediate the impact of the number of painful stimuli on life satisfaction.

The impact of chronic orofacial pain on daily life: the vulnerable patient and disruptive pain

OBJECTIVE

To identify patient and pain characteristics associated with negative impacts on daily life among patients with chronic orofacial pain (COFP).

STUDY DESIGN

Medical records of 200 COFP patients were analyzed.

RESULTS

Diagnostic categories included temporomandibular disorders (85; 42.7%), headaches (47; 23.6%), neuropathic pain (37; 18.5%), trigeminal neuralgia (16; 8.0%), and painful posttraumatic trigeminal neuropathy (PTTN) (14; 7.0%). Of these, 47 (23.7%) had medical and 13 (6.5%) had psychiatric comorbidities and 71 (35.7%) experienced physical trauma. Seven (5%) had stopped working, and mean days absent from work was 3.3 ± 19.3. Patients were previously treated by 2.7 ± 1.4 caregivers. Mean scores on a 0-10 scale were as follows: pain (7.13 ± 2.3), sleep quality (6.6 ± 2.4), and quality of life (5.58 ± 3.1). PTTN patients were more likely to quit work (P = .009) and had more days absent from work (mean 24.3; P = .009). We identified patient and pain profiles that predict these poor outcomes. The "vulnerable patient" profile includes health and psychiatric comorbidities and trauma history, particularly PTTN. The "disruptive pain" profile includes severe, continuous, burning, electrical pain accompanied by systemic signs. These profiles intersect in a complex manner, creating a complex feedback loop.

CONCLUSIONS

A multidisciplinary team approach is recommended to manage COFP patients, in order to improve treatment outcomes and avert more serious consequences.

Impact of indoor facilities management on the quality of life of the elderly in public housing

Purpose

The aging population is growing rapidly, causing significant increases in the demand for public housing. Normally, the elderly rely heavily on the facilities available in their living environment to maintain their quality of life (QoL). However, most public housing is not purposely designed for the elderly, and, thus, has inappropriate facilities, which often have a negative impact upon the physical and psychological health of residents. This paper aims to investigate the relationships between the indoor facilities management (FM) of public housing and the QoL of elderly persons.

Design/methodology/approach

Based on an extensive literature review, a questionnaire has been designed and distributed among elderly residents of different public housing buildings. To investigate the impact of indoor FM on the QoL of the senior residents in public housing, statistical analysis methods including reliability analysis and multiple regression modeling were adopted.

Findings

The study identified 12 indoor FM factors and six QoL domains (i.e. overall QoL, physical and psychological health, independence, social relationship and living environment). The results also reveal that space planning and bathroom influence most QoL domains, including overall QoL, physical/psychological health, independence and living environment of the elderly; electricity and noise mainly affect physical health and independence, while noise is negatively related to elderly QoL; and supporting facilities (including windows and doors, indoor decoration, non-slip floors and accessibility) have a positive impact on psychological health and social relationships.

Practical implications

Based on the current findings, several practical recommendations are made for the designers and facilities managers, including wide corridors for individuals with wheelchairs, the installation of single-lever-type mixers to provide a stable hot water supply and a window designed to get as much natural light as possible.

Originality/value

This paper provides a clear picture about elderly special requirements on indoor FM and their QoL. It can assist architects, engineers and facilities managers in public housing to understand elderly needs and improve FM during design and operation stages for enhancing QoL of elderly residents in public housing buildings.

Quality of Life in Hospice Patients with Terminal Illness

To better understand quality of life (QOL) and its important correlates among patients with terminal illness, a cross-sectional correlational design was used in a study based on Stewart, Teno, Patrick, and Lynn’s conceptual model of factors affecting QOL of dying patients and their families. Sixty participants were recruited from two local hospice programs in the midwestern region of the United States. Data were collected at the participants’ homes. The participants had an above average QOL. Living with the caregiver, spirituality, pain intensity, physical performance status, and social support as a set explained 38% of the variance in their QOL. Among these five predictors, living with the caregiver, spirituality, and social support statistically were significant predictors of the QOL of these participants. Participants who did not live with their caregivers experienced less pain intensity, perceived higher spirituality, had more social support, and had a significantly better QOL. Important contributions of these findings are discussed.

[Pain in the elderly: Quality of life, functionality and associated factors. SABE Study, Bogotá, Colombia]

OBJECTIVE

To determine the impact of pain on the quality of life in older adults and its association with functionality.

MATERIALS AND METHODS

Data was taken from SABE Bogota study. A cross-sectional study was carried out during 2012, interviewing 2,000 individuals of 60 years and older, as a probabilistic cluster and representative sample. The variable 'presence of pain' to was used to identify associations with sociodemographic factors, self-rated health, comorbidities, functional status, cognitive status, and quality of life. The latter was estimated using a visual analogue scale of the EuroQOL tool (EQ-VAS).

RESULTS

The majority of older adults were women (63.4%); the mean age was 71.17 years (SD=8.05), with a higher frequency of individuals in the age group between 60 and 69years (48%). When comparing groups with pain vs. no pain, significantly lower scores were found in the group with pain (P<.001) in both the functionality and quality of life EQ-VAS scales. The strongest associations with pain were: joint diseases (OR: 3.08 [2.24-4.23]), severe depression (OR: 2.80 [1.63-4.79]) and functional impairment of the Basic Activities of Daily Living (BADL) (OR: 2.45 [1.31-4.58]).

CONCLUSIONS

Pain negatively impacts the functional independence and the perception of the quality of life in older adults, predisposing them to adverse outcomes.

Correlates of a Single-Item Quality-of-Life Measure in People Aging with Disabilities

Objective

Practical quality-of-life (QOL) screening methods are needed to help focus clinical decision-making on what matters to individuals with disabilities.

Design

A secondary analysis of a database from a large study of adults aging with impairments focused on four diagnostic groups: cerebral palsy (n = 134), polio (n = 321), rheumatoid arthritis (n = 99), and stroke (n = 82). Approximately 20% of cases were repeated measures of the same individuals 3–5 yrs later. Functional levels, depression, and social interactions were assessed. The single-item, subjective, seven-point Kemp Quality of Life Scale measured QOL. For each diagnostic group, Kemp Quality of Life Scale responses were divided into low, average, and high QOL subgroups. Analysis of variance and Tukey honestly significant difference tests compared clinical characteristics among these subgroups.

Results

Duration of disability varied among the four groups. Within each group, QOL subgroups were similar in age, sex, and duration of disability. Low mean QOL was associated with lower functional level, higher depression scores, and lower social interaction (P < 0.001) in all four groups. In contrast, high mean QOL was associated with higher social interaction (P < 0.001).

Conclusion

The Kemp Quality of Life Scale relates significantly to clinically relevant variables in adults with impairments. The scale’s utility in direct clinical care merits further examination.
